Specifically, the first filter 12 can separate the dust-containing gas in the cleaning device 100 from the dust and gas, and the dust cup 11 is covered on the outside of the first filter 12 to collect the dust collected by the first filter 12. The end of the cup cover 112 is provided with an ash pouring port, the cup cover 112 covers the ash pouring port and can be opened, the dust in the cup body 111 can be discharged from the ash pouring port, and the dust in the cup body 111 can be cleaned. More specifically, the air inlet pipe 18 and the cup body 111 are arranged side by side and extend in the same direction, which can be beneficial to space arrangement and improve the compactness of the device structure. At least a portion of the scraping assembly is sleeved on the outside of the first filter 12 and is suitable for reciprocating along the axial direction of the first filter 12 to scrape the first filter 12, thereby scraping off the dust on the outside of the first filter 12 to prevent the first filter 12 from being blocked, achieving a cleaning effect, and helping to improve the use effect of the first filter 12 and facilitate dust collection. Specifically, the cup body 111, the first filter 12, the scraping assembly and the air inlet pipe 18 extend in the same direction, which is beneficial to reducing the size of the cleaning device 100 and facilitating space arrangement on the one hand, and on the other hand, the air inlet pipe 18 can be arranged on the outer peripheral wall of the cup body 111 and extend along the axial direction of the cup body 111, so that the airflow can flow in a spiral after entering the cup body 111 from the air inlet pipe 18, which is beneficial to improving the separation effect, and the scraping assembly can scrape off the separated dust from the first filter 12, thereby helping to improve the cleaning effect and facilitate dust collection and cleaning.

According to the cleaning device 100 of the embodiment of the present application, by providing a dust scraping component, it is possible to facilitate cleaning of the filter, improve the cleaning effect of the first filter 12, and provide convenience for users.

In actual application, during the cleaning process of the cleaning device 100, dust and dirt are constantly accumulated on the first filter 12. If it is not cleaned for a long time, the filter is easily blocked, thereby reducing the filtering effect or reducing the dust suction wind force. Therefore, during use, the scraping component can be driven to move so that the scraping component can move on the outside of the first filter 12 to scrape off the dust and dirt on the outer surface of the filter. The scraped dust and dirt can be directly collected in the cup body 111. The scraping component can be manually driven or automatically or electrically driven. For example, the user can scrape the dust by manually moving the scraping component, or by pressing a button to drive the scraping component to run. Alternatively, a detection device can be set in the dust cup. When there is a lot of dust on the first filter 12, the scraping component is automatically started or the user is prompted to clean the first filter 12, etc. The present application is not limited to this.

For example, when a lot of dust accumulates on the outside of the first filter 12, the user can feel that the scraping component encounters resistance when it moves. As the cleaning work proceeds, the dust on the outside of the first filter 12 is cleaned, and the movement of the scraping component gradually becomes smoother. The user can confirm the cleaning effect by feeling the changes in the hand feel during the cleaning process.

In conjunction with FIG. 2 and FIG. 3 , in some embodiments of the present application, further, the cleaning device 100 includes a scraping unit 20 and an operating unit 30. Specifically, the scraping unit 20 is sleeved on the outer peripheral surface of the first filter 12, and is suitable for reciprocating along the axial direction of the first filter 12 to scrape dust, and is used to scrape dust on the outside of the first filter 12, which can improve the scraping effect, and occupies less space, which is conducive to space layout. The operating unit 30 is connected to the scraping unit 20 in a transmission manner, and is used to drive the scraping unit 20 to move, and the operating unit 30 is configured to drive the cup cover 112 to open. In other words, the operating unit 30 can not only drive the scraping assembly to move to clean the first filter 12, but also can be used to open the cup cover 112. The user does not need to open the cover manually, which can avoid dust and secondary pollution, and provide convenience for the user.

In the related art, the user needs to hold the cleaning device with one hand to open the cover, and the user needs to hold the cover with one hand to open the cover, which easily causes dust and is inconvenient to operate. According to the cleaning device 100 of the embodiment of the present application, after the cleaning device 100 has been working for a period of time, there is a lot of dust in the cup body 111. When cleaning is needed, the cup cover 112 can be driven to open by the control operation unit 30, which can facilitate cleaning of the dust in the cup body 111. The user can operate it with one hand to drive the operating part 30 to automatically open the lid, which brings convenience to the user. When cleaning the cup body 111, the ash pouring port can be aligned with the dust collecting device or the garbage bag in advance. When the operating part 30 drives the cup lid 112 to open, the dust in the cup body 111 can directly enter the dust collecting device or the garbage bag to avoid dust overflow.

The guide portion 60 is provided with a guide hole for the guide rod 21 to pass through, and guides the axial movement of the guide rod 21, so that the scraper assembly can extend axially on the main body 10, which can save space and improve the compactness of the device. In addition, the guide portion 60 can limit the guide rod 21 in the radial direction to prevent the scraper assembly from shaking during use.

In conjunction with FIG. 3 , in some embodiments of the present application, the scraping assembly further includes a spring 24, which is sleeved on the guide rod 21, and the two ends of the spring 24 are respectively against the guide portion 60 and the support portion 23, and the spring 24 is configured to have a force to drive the scraping assembly to move in a direction away from the cup cover 112, so as to provide a reset force for the scraping portion 20, so that the scraping portion 20 can automatically reset, which is convenient for users to use. When in use, the operating portion 30 can drive the scraping assembly to move in a direction close to the cup cover 112, so as to scrape the dust through the outer side of the first filter 12, at which time, the support portion 23 also moves in a direction close to the cup cover 112 or the guide portion 60, and the spring 24 is abutted between the support portion 23 and the guide portion 60 and is compressed. When the driving force disappears, the reset force of the spring 24 can drive the support portion 23 and the scraping portion 20 to reset, so as to simplify the operation.

In conjunction with FIG. 2 and FIG. 3 , in some embodiments of the present application, the operating portion 30 is configured to be suitable for driving the cup cover 112 to open; the dust cup 11 also includes a locking portion 14, one side of the cup cover 112 is hinged to the cup body 111, and the other side is locked with the cup body 111 by the locking portion 14, and the operating portion 30 includes a resisting portion 31, and the resisting portion 31 is suitable for resisting the locking portion 14 to open the cup cover 112, which can realize automatic opening of the cover and avoid manual operation. Specifically, the locking portion 14 can lock the cup cover 112 when the cup cover 112 closes the ash pouring port, and when the cover needs to be opened, the operating portion 30 resists the locking portion 14 to realize unlocking of the locking portion 14, and the locking portion 14 can release the cup cover 112, thereby, one side of the cup cover 112 is connected to the cup body 111, and the other side is separated from the cup body 111, so that the ash pouring port can be opened.

In conjunction with FIG. 4 , in some embodiments of the present application, the locking portion 14 is rotatably connected to the dust cup 11, and the locking portion 14 has a trigger end 141 and a lock hook 142. The lock hook 142 hooks the cup cover 112, and the abutment portion 31 is suitable for abutting the trigger end 141 to allow the lock hook 142 to unlock the cup cover 112. Specifically, the lock hook 142 has a locked state and an unlocked state. The lock hook 142 can be used to lock the cup cover 112 in the locked state. The trigger end 141 is in transmission connection with the lock hook 142, so that the trigger end 141 can control the state of the lock hook 142, and the lock hook 142 can be adjusted from the locked state to the unlocked state, so that the lock hook 142 releases the cup cover 112.

In conjunction with FIG. 1 and FIG. 3, in some embodiments of the present application, the scraping assembly has a first position, a second position and a third position in the axial direction, and the distance of the scraping assembly relative to the cup cover 112 gradually decreases in the first position, the second position and the third position, and drives the cup cover 112 to open in the third position. That is to say, the operating part 30 can drive the scraping assembly to move between the first position and the third position, and the effect of scraping and opening the cover can be achieved. For example, since the first filter 12 is arranged in the cup body 111, and the cup cover 112 is arranged at the end of the cup body 111, therefore, when the operating part 30 controls the scraping assembly to move between the first position and the second position, the scraping assembly passes through the outside of the first filter 12, and has a scraping effect; when the operating part 30 controls the scraping assembly to gradually move to the third position, it gradually approaches the cup cover 112, so that the operating part 30 can resist the unlocking member. In addition, by setting the third position, and the third position is closer to the cup cover 112 relative to the second position, during the scraping operation, the resistance part 31 and the locking part 14 are at a certain distance, which can prevent the user from accidentally touching the operating part 30 and opening the cup cover 112 during the scraping operation, thereby improving the reliability of use.

Furthermore, the dust scraping assembly is configured such that the damping from the first position to the second position is smaller than the damping from the second position to the third position, so that the user can scrape dust easily and can easily identify the control state of the operating unit 30. Specifically, the dust scraping assembly has a small damping when moving between the first position and the second position, so that the user can control the operating unit 30 with a small force, and the dust scraping assembly has a large damping when moving from the second position to the third position, so that when the user manually operates, some force is required to control the operating unit 30 to open the cup cover 112, which can avoid accidental touch and opening of the cover, and due to the different damping sizes, a prompt can also be provided to the user, and the user can judge the position and state of the dust scraping assembly according to different hand feelings.

Of course, a limiting structure may be provided between the second position and the third position, and the operating portion 30 needs to go over the limiting structure to contact the locking portion 14, which can provide operation feedback to the user and improve the use effect.

In some embodiments of the present application, the cleaning device 100 further includes a damping structure, which is configured to provide damping for the movement of the operating part 30 from the second position to the third position. That is, there is no damping effect when the operating part 30 moves between the first position and the second position, so that the user can more easily drive the scraping assembly to move between the first position and the second position; when the operating part 30 moves from the second position to the third position, it is necessary to overcome the damping force. When the operating part 30 reaches the third position, the resistance part 31 can trigger the locking part 14 to open the cup cover 112, which can avoid opening the cup cover 112 due to operating errors, and can also obtain a hand feeling that can distinguish the operating state of the operating part 30, so that it is convenient for the user to judge the working state of the scraping assembly.

The first position and the second position are arranged at two ends of the axial direction of the first filter 12 , so that the dust scraping assembly can scrape off the dust on the outside of the first filter 12 when moving between the first position and the second position.

Specifically, the power supply assembly 73 can be used to support the main body 10, and when the cleaning device 100 is placed, the power supply assembly 73 is supported on the table for easy storage. The handle 71 is connected between the power supply assembly 73 and the main body 10, which can not only play a supporting role, but also the user can put his hand into the interval between the power supply assembly 73 and the main body 10, so that the user can hold the cleaning device 100 and carry out mobile cleaning. Further, when the user needs to use the scraping assembly, the user can directly pull the finger forward to the operating part 30 connected to the air inlet pipe 18, so that the user can operate with one hand, which provides convenience for the user.

2 , a battery is also provided in the power supply component 73 to provide a storage space for the battery, so that the user can use the battery energy to drive the cleaning device 100 to work when the power is off, and placing the battery in the power supply component 73 is beneficial to improving the stability of the power supply component 73, so that the center of gravity of the cleaning device 100 is lower, which is conducive to stable placement.

In conjunction with Figure 1, in some embodiments of the present application, the inlet 108 of the air inlet duct 18 and the ash discharge port of the cup body 111 face in the same direction, which is beneficial to improving the cleaning effect of the cleaning device 100. Generally, when using it, the user will align the inlet 108 with the position that needs to be cleaned, so that the surface to be cleaned is in contact with the inlet 108 to improve the cleaning effect. When this side of the cleaning device 100 contacts the surface to be cleaned, the fit effect between the cleaning device 100 and the surface to be cleaned can be improved, and it is also easier for the user to move, which is convenient for the user to operate and is beneficial to improving the dust collection effect.

Specifically, the second filter 13 is located in the front part of the motor 40 on the airflow path. When in use, the airflow first enters the second filter 13 for filtering and then flows toward the motor 40, which is beneficial to improve the cleaning effect and protect the motor 40. Therefore, in order to improve the filtering effect and facilitate the user to quickly disassemble and clean the second filter 13, a handle 131 can be provided on the second filter 13 and cooperate with the dust cup 11 to improve the assembly efficiency. When in use, the second filter 13 can be inserted into the main body 10, and the main body 10 is provided with a clamping part, which can improve the stability of the installation of the second filter 13, and a sealing ring is provided between the second filter 13 and the main body 10 and the cup cover 112. Alternatively, after the second filter 13 is inserted, the second filter 13 is rotated to find the docking portion, and the filter 13 is abutted or engaged with the docking portion.

Furthermore, the main body 10 also includes a third filter 15, which is located at the rear of the motor 40 in the air flow path. When in use, the air flow flows toward the motor 40 and is discharged from the third filter 15, which is beneficial to improve the cleanliness of the exhaust gas and avoid secondary pollution.

A cleaning device according to a specific embodiment of the present application is described below with reference to the accompanying drawings.

In conjunction with Figures 1 to 5, the cleaning device 100 according to the embodiment of the present application includes: a main body 10, a dust cup 11 connected to the main body 10, a handle 71, a motor 40, a power supply assembly 73, an air inlet pipe 18, a first filter 12, and a second filter 13 and a third filter 15 connected to the motor 40. In this embodiment, the cleaning device 100 adopts side air intake, so the inlet 108 is located on one side of the dust cup 11. The second filter 13 and the third filter 15 are respectively located in front and rear of the motor 40 on the airflow path for filtering the airflow respectively, and the third filter 15 may overlap with the motor 40 in space according to actual conditions. The dust cup 11, the motor 40, and the third filter 15 are arranged in sequence along the longitudinal axis direction of the dust cup 11, and the second filter 13 is located inside the dust cup 11. The power supply assembly 73 is located at the bottom of the cleaning device 100 and can support the entire device. The handle 71 is located between the motor 40 and the power supply assembly 73. The axis of the handle 71 does not pass through the motor 40. The motor 40 is further rearward relative to the axis of the handle 71, and the center of gravity is backward to avoid the user's wrist exerting extra force when using it, which is conducive to improving the feel of use. The cleaning device 100 has a relative distal end and a proximal end, the inlet 108 is located at the distal end, and the third filter 15 is located at the proximal end. In conjunction with Figure 2, the distal end can be the front end and the proximal end can be the rear end.

The dust cup 11 includes a cup body 111 and a cup cover 112 for pouring dust. The first filter 12 is arranged in the cup body 111, wherein the first filter 12 can be a filter screen with a plurality of through holes on the surface for filtering dust with larger particle sizes. A multi-cone cyclone can also be provided in the dust cup 11. The multi-cone cyclone includes a plurality of small cones, which are arranged in the dust cup 11 and downstream of the first filter 12 to perform further filtering and improve the filtering effect. The dust cup 11 is also provided with a locking portion 14 for locking and unlocking the cup cover 112.

In conjunction with Figure 3, the cleaning device 100 also includes a scraping assembly, which includes an operating part 30, a connecting rod 50 connected to the operating part 30, a supporting part 23 fixed inside the main body 10, and a scraping part 20 connected to the supporting part 23. The scraping part 20 is in contact with the outer wall of the first filter 12 and is located at one end of the first filter 12 close to the motor 40 in the initial position.

Specifically, three guide rods 21 are arranged between the support part 23 and the scraper part 20 to connect and transmit the movement of the operating part 30. One end of the connecting rod 50 is connected to the operating part 30, and the other end of the connecting rod 50 is connected to at least one of the guide rods 21, so as to drive the scraper part 20 to move when the connecting rod 50 moves. The support part 23 is arranged around the periphery of the motor housing 16 and can move along the motor housing 16 when the operating part 30 is pushed. Since the scraper part 20 is connected to the support part 23 through the guide rods 21, when the support part 23 moves along the motor housing 16, the scraper part 20 moves in the same direction and scrapes the dust on the periphery of the first filter 12.

Furthermore, a spring 24 is sleeved on the guide rod 21. When scraping dust, the movement of the support part 23 compresses the spring 24. When the scraping action is finished, the scraping part 20 automatically resets due to the restoring force of the spring 24. The operating part 30 is located below the dust cup 11. This position can make it more convenient for users to push and pull, making the push and pull action smoother.

According to the cleaning device 100 of the embodiment of the present application, the dust cup 11 does not move during the scraping process, and only the scraping part 20 moves inside the dust cup 11. The principle of scraping dust is: during the scraping operation, the user pushes the operating part 30, and the operating part 30 drives the connecting rod 50 to move. The movement of the connecting rod 50 drives the supporting part 23 to move along the outer periphery of the motor cover 16, and the movement of the supporting part 23 drives the scraping part 20 to contact the outer periphery of the first filter 12 to scrape dust. At this time, the spring 24 is compressed, and the push-pull action of scraping dust can be operated multiple times. By repeatedly moving the scraping part 20, the dust on the outside of the first filter 12 can be scraped more cleanly; at the end of the scraping operation, under the action of the elastic restoring force of the spring 24, the operating part 30 returns to the initial position, and then drives the scraping part 20 to move to the initial position. By setting up the scraping assembly, the dust and dirt accumulated on the first filter 12 can be scraped every time the dust is poured, and regular cleaning can be carried out to avoid clogging of the filter net and affecting the dust suction wind force of the cleaning device 100; and there is no need to disassemble the dust cup 11, the operation is simple and convenient, and the dust removal effect is good.

In addition, the scraping assembly has no connection or matching relationship with the outer wall or inner wall of the dust cup 11, and the inner wall of the entire dust cup 11 is a complete annular wall. This arrangement ensures the continuity of the airflow inside the dust cup 11 and avoids disruption of the airflow.

Furthermore, the operating part 30 also includes a resistance part 31, which is located at the end of the connecting rod 50 near the operating part 30. When the scraping part 20 moves to the end of the stroke (the third position) or moves close to the end of the stroke (the third position), the resistance part 31 presses against the locking part 14 of the dust cup 11 to unlock it, so that the cup cover 112 opens. After the scraping operation is completed or during the process, the cup cover 112 is opened to achieve scraping and dust dumping operations. At this time, the user will operate the trash can. Since the dust cup 11 is placed horizontally in the present application, the garbage is directly poured into the trash can from the front end of the dust cup 11, which avoids dust overflowing and preventing dust from falling back on the clean floor. At the same time, the user only needs to push the operating part 30 and does not need to touch the vicinity of the cup cover 112, thereby avoiding contact with dust and improving the user experience.

During actual use, the airflow path of the entire device is as follows: the airflow enters the air inlet pipe 18 from the inlet 108, the dust and air enter the dust cup 11 from the side of the dust cup 11, and the dust falls into the first dust collecting space after being filtered by the first filter 12. The airflow containing a small amount of dust continues to enter the multi-cone cyclone for filtration, and the filtered fine dust falls into the second dust collecting space. The airflow continues to enter the second filter 13 for filtration and flows toward the motor 40, and finally passes through the third filter 15 and is discharged from the outlet 109.

Specifically, dust and air enter from the suction port and enter the dust cup 11 tangentially along the air duct. Under the action of centrifugal force, dust and debris rotate along the wall of the dust cup 11 to the first dust collecting space of the dust cup 11. A flange at a certain angle to the horizontal direction is set below the filter screen cover. The flange at the bottom of the filter screen cover can prevent the dust that enters the bottom due to centrifugal force from entering the multi-cone cyclone again, effectively reducing the total amount of dust entering the multi-cone cyclone. Part of the dust passes through the filter screen cover and enters the multi-cone cyclone. Similarly, under the action of centrifugal force, the dust rotates along the wall of the multi-cone cyclone to the second dust collecting space at the bottom. At the dust-gas separation port, the gas enters the second filter 13 through the porous air passage and then enters the motor 40. It is then filtered by the third filter 15 and discharged. In this case, by setting up two cyclone filtrations and using a multi-cone cyclone mechanism for secondary filtration, the separation efficiency of dust and air can be greatly increased, the number of times the filter is cleaned, and the service life of the filter can be extended.

The second filter 13 is located inside the first filter 12. A handle 131 is provided at the end of the second filter 13, and the handle 131 is used to take out the second filter 13 along the longitudinal axis of the dust cup 11. The handle 131 of the second filter 13 is provided near the cup cover 112, and the second filter 13 is disassembled in a direction away from the cup cover 112. The third filter 15 can be disassembled backwards, and such an arrangement can facilitate the cleaning of the second filter 13 and the third filter 15. The second filter 13 is coaxially arranged with the first filter 12. The second filter 13 includes filter cotton and a filter bracket. After being filtered by the filter cotton, the airflow enters the interior through a number of through holes on the filter bracket, and flows from the internal channel toward the motor 40. As stated above, in order to allow the second filter 13 to be quickly disassembled and cleaned, the second filter 13 is located in the middle of the dust cup 11, and is connected to the fan assembly through a sealing ring at the top. The gas after dust and gas separation enters the first filter 12 through the porous air passage and then enters the motor 40 before being discharged. Usually, a small amount of fine ash will be attached to the outer wall of the second filter 13. When the second filter 13 needs to be cleaned, just hold the handle 131 of the second filter 13 at the opening at the bottom of the dust cup 11 and pull it out. After cleaning, it can be assembled in the same way. In this way, the second filter 13 can be quickly cleaned or replaced without disassembling any other components, thereby greatly improving user convenience and satisfaction.

A power switch is provided above the handle 71, which is located on the housing or where the screen is located. The cleaning device 100 is also provided with a rear end cover, and the display screen faces rearward and is provided on the rear end cover. When disassembling, the rear end cover is first removed, and then the third filter 15 is removed for cleaning.

In combination with Figures 1 to 7, the cleaning device 100 according to the embodiment of the present application includes: a main body 10 and a dust cup 11. The main body 10 has a first filter 12. The first filter 12 can separate the gas containing dust in the cleaning device 100 from the dust and gas. The dust cup 11 is connected to the main body 10. The dust cup 11 is covered on the outside of the first filter 12, so that the dust cup 11 can be used to collect dust generated after filtering by the first filter 12.

Furthermore, the dust generated by the filtration of the first filter 12 is distributed in the space formed between the first filter 12 and the dust cup 11. Since the first filter 12 may filter out some lighter dust, the dust is distributed in a flocculent state between the dust cup 11 and the first filter 12, which not only easily blocks the first filter 12 and affects the dust collection effect, but also adheres to the wall of the dust cup 11 when cleaning the dust cup 11 and cannot be poured out, or generates dust when the user pours it out, causing secondary pollution. Therefore, the cleaning device 100 is also provided with a scraping assembly, which is used to squeeze the dust between the first filter 12 and the dust cup 11 to facilitate dust collection. Specifically, the scraping assembly has a scraping part 20, which is arranged between the dust cup 11 and the first filter 12, and a dust pressing space 101 is formed between the scraping part 20 and the bottom wall of the dust cup 11. The scraping part 20 covers one end of the dust pressing space 101 and is movable along the axis of the first filter 12. That is to say, the scraping part 20 can move in the dust pressing space 101. During the movement of the scraping part 20, the scattered flocculent dust in the dust pressing space 101 can be collected to one end of the dust pressing space 101. In this way, it can prevent flocculent or lighter dust from affecting the operation of the first filter 12. After the dust is compacted by the scraping part 20, the dust scattered in the dust pressing space 101 is compressed, which reduces the space occupied by the dust in the dust pressing space 101, and is conducive to increasing the dust collection capacity of the dust cup 11. In this way, the user does not need to frequently dump the dust in the dust cup 11, which can reduce the cleaning time and provide convenience for the user. In addition, when the scraping component collects and compresses dust, it can also improve the cleanliness of the dust cup 11, which can avoid dust or dust when the user cleans or opens the dust cup 11. The phenomenon of dust spraying.

According to the cleaning device 100 of the embodiment of the present application, by setting a dust scraping assembly between the first filter 12 and the dust cup 11, the dust in the dust cup 11 can be collected and compressed, which is beneficial to improve the cleaning effect of the dust cup 11 and avoid the problem of dust spraying or dust raising when the dust cup 11 is opened, thereby avoiding secondary pollution and facilitating user use.

In conjunction with FIG. 3 and FIG. 5 , in some embodiments of the present application, the scraping part 20 is sleeved on the outside of the first filter 12, and the scraping part 20 has an extrusion piece 25 extending toward the inner wall of the dust cup 11 and adjacent to the inner wall of the dust cup 11, and the extrusion piece 25 is suitable for moving along the axial direction of the first filter 12 to squeeze the dust in the dust pressing space 101. In other words, the extrusion piece 25 can extend from the outside of the first filter 12 to a position adjacent to the inner wall of the dust cup 11, which is conducive to expanding the pressure gray space 101, facilitating the compression of more dust, and improving the collection and compression effect of dust. Specifically, when the distance between the extrusion piece 25 and the inner wall of the dust cup 11 is reduced, the cleaning effect of the extrusion piece 25 on the dust near the inner wall of the dust cup 11 and the dust attached to the inner wall of the dust cup 11 can be improved, and the dust cup 11 can be cleaned while the dust is compressed, thereby reducing the work of the user to clean the dust cup 11. Of course, the size of the extrusion piece 25 can also be adjusted according to the actual situation, which is conducive to the size of the first filter 12 or the dust cup 11 or the actual application scenario, and the present application is not limited thereto.

In conjunction with FIG. 5 , in some embodiments of the present application, the extrusion piece 25 has a first side wall and a second side wall that are arranged opposite to each other in the axial direction, the first side wall is arranged opposite to the outer side of the first filter 12 in the radial direction of the first filter 12, and the second side wall is arranged opposite to the inner wall of the dust cup 11 in the radial direction of the first filter 12. Specifically, the extrusion piece 25 may be in a form having a certain thickness in the axial direction of the first filter 12, so that the structural stability and operational stability of the extrusion piece 25 can be improved, the extrusion effect of the extrusion piece 25 on dust can be improved, and dust can be compacted. The contact area when the extrusion piece 25 cooperates with the first filter 12 or the inner wall of the dust cup 11 can also be increased to improve the cleaning effect.

3 to 6 , in some embodiments of the present application, a scraper 22 is connected to the first side wall. The scraper 22 extends along the axial direction of the first filter 12 and is suitable for gap fitting with the outer side of the first filter 12 .

Specifically, the scraper 22 is sleeved on the outer peripheral surface of the first filter 12, and is suitable for reciprocating along the axial direction of the first filter 12 to scrape dust, and is used to scrape dust on the outside of the first filter 12, which can improve the cleaning effect of the first filter 12, and the scraper 22 is integrated in the scraper assembly, which occupies less space and is conducive to space layout. In other words, the scraper 20 can clean the outer surface of the first filter 12 to prevent dust from adhering to the outside of the first filter 12 and affecting the filtering effect or the cleaning effect of the cleaning device 100. At the same time, the scraper 20 can also collect dust in the dust pressing space 101. In particular, when the scraper 20 is working, after the scraper 22 scrapes off the dust on the outside of the first filter 12, the dust is scattered in the dust pressing space 101 and can be directly collected and compressed by the extruder 25, thereby further improving the cleaning effect and improving the functionality of the scraper assembly.

In some embodiments of the present application, the first side wall and the outer side of the first filter 12 are matched with a gap, that is, the first side wall and the outer side of the first filter 12 can be matched with a gap (including a minimum gap equal to zero). The gap between the first side wall and the outer side of the first filter 12 can improve the movement flexibility of the extrusion member 25 and facilitate user use. In conjunction with Figure 6, when the gap between the first side wall and the first filter 12 is small or zero, the matching effect between the first side wall or the scraper 22 on the first side wall and the first filter 12 can be improved, which is conducive to cleaning the first filter 12. Among them, the scraper 22 can be integrated on the first side wall, or the scraper 22 and the first side wall can be in a form of being integrally formed, etc., and the present application is not limited to this.

In some embodiments of the present application, the second side wall and the inner wall of the dust cup 11 are matched with a gap, that is, there can be a gap (including a minimum gap equal to zero) between the second side wall and the inner wall of the dust cup 11. When there is a gap between the second side wall and the inner wall of the dust cup 11, the movement flexibility of the extrusion member 25 can be improved, which is convenient for users to use. When the gap between the second side wall and the inner wall of the dust cup 11 is small or zero, the matching effect between the second side wall and the inner wall of the dust cup 11 can be improved, and the inner wall of the dust cup 11 can be cleaned during the process of squeezing and scraping dust.

In some embodiments of the present application, the scraping part 20 is a flexible structure and/or the scraping part 20 has bristles (not shown in the figure), which can protect the components in the cleaning device 100, improve the flexibility during movement or use, and also help to improve the cleaning effect, wherein the bristles can be arranged toward the inner wall of the dust cup 11, so as to clean the inner wall of the dust cup 11 during the movement of the scraping part 20, thereby improving the cleaning effect of the dust cup 11. For example, the scraping part 20 can be a soft rubber strip or a ring-shaped soft rubber strip, so as to reduce the weight of the scraping part 20 and the flexibility during movement. In actual use, since the scraping part 20 is in contact with dust for a long time and is easily contaminated, the soft rubber strip is easy to replace and purchase, and the user can also replace the rubber strip after using it for a period of time to improve the cleanliness of the device.

The scraper 20 may also have bristles, which may be arranged on one side close to the inner wall of the dust cup 11, so that when the scraper 20 moves, it can clean the inner wall of the dust cup 11, and can clean off the dust attached to the inner wall of the dust cup 11, and squeeze the dust through the extruder 25, so as to improve the cleaning effect of the dust in the dust cup 11, and help improve the automatic cleaning effect of the dust cup 11. Therefore, when the user cleans the dust cup 11, the dust in the dust cup 11 is squeezed into blocks, which can be poured out directly, and the squeezed dust will not be raised when it is poured, which can avoid causing the second At the same time, the inner wall of the dust cup 11 is also cleaned by the scraping part 20, which provides convenience for the user to clean the dust cup 11.

In combination with Figures 4 and 5, in some embodiments of the present application, the scraper assembly also includes: a guide rod 21 and a support portion 23. The support portion 23 is connected to the scraper member 22 through the guide rod 21, and can axially support the scraper member 22 to prevent the scraper member 22 from shaking during movement, thereby improving the structural stability and operational stability of the scraper member 22. In this way, when larger dirt is attached to the outside of the first filter 12, the scraper member 22 can also scrape it off, which is beneficial to improving the cleaning effect and durability.

Furthermore, the guide rod 21 extends along the axial direction of the first filter 12, and one end of the guide rod 21 is connected to the scraper 20; the support portion 23 is connected to the other end of the guide rod 21 and is movably supported on the main body 10, wherein the support portion 23 is transmission-connected to the operating portion 30. The guide rod 21 extends along the axial direction, can guide the scraper 22 to move along the axial direction, and can also play a supporting role between the support portion 23 and the scraper 22, which is conducive to dispersing the force.

Specifically, the support portion 23 can be arranged between the motor housing 16 and the outer shell of the cleaning device 100, which is convenient for accommodating the support portion 23, and the support portion 23 can move axially along the motor housing 16, and when the support portion 23 moves, the dust scraping member 22 can also move axially outside the first filter 12.

In conjunction with FIG. 3 , in some embodiments of the present application, the scraping assembly further includes a spring 24, which is sleeved on the guide rod 21, and the two ends of the spring 24 are respectively against the guide portion 60 and the support portion 23, and the spring 24 is configured to have a force to drive the scraping portion 20 to reset, so as to provide a reset force for the scraping member 22, so that the scraping member 22 can automatically reset, which is convenient for users to use. When in use, the operating portion 30 can drive the scraping assembly to move toward the direction close to the cup cover 112 to scrape the dust through the outer side of the first filter 12. At this time, the support portion 23 also moves toward the direction close to the cup cover 112 or the guide portion 60, and the spring 24 is abutted between the support portion 23 and the guide portion 60 and is compressed. When the driving force disappears, the reset force of the spring 24 can drive the support portion 23 and the scraping member 22 to reset, so as to simplify the operation.

In conjunction with FIG. 1 and FIG. 2, in some embodiments of the present application, the cleaning device 100 includes an air inlet pipe 18, the air inlet pipe 18 and the dust cup 11 are arranged side by side, the scraping assembly and the air inlet pipe 18 extend in the same direction, and the scraping assembly is located outside the air inlet pipe 18. Specifically, the air inlet pipe 18 and the dust cup 11 are arranged side by side and extend in the same direction, which can be beneficial to space arrangement and improve the compactness of the device structure. Among them, the scraping assembly is located outside the air inlet pipe 18, and the dust cup 11, the first filter 12, the scraping assembly and the air inlet pipe extend in the same direction. On the one hand, it is beneficial to reduce the size of the cleaning device 100 and facilitate space arrangement. On the other hand, the air inlet pipe can be arranged on the outer peripheral wall of the dust cup 11 and extend along the axial direction of the dust cup 11. In this way, the airflow can flow in a spiral after entering the dust cup 11 from the air inlet pipe 18, which is beneficial to improve the separation effect. The scraping assembly can collect and compress the dust in the dust pressing space 101, thereby improving the cleaning effect and facilitating the collection and cleaning of dust.

In conjunction with Figure 2, in some embodiments of the present application, the cleaning device includes a motor pre-filter 13, which is at least partially located in the dust cup 11, which can improve the filtering effect. The scraping part 20 moves along the axial direction of the motor pre-filter 13, which is beneficial to spatial arrangement and easy to assemble.

A cleaning device 100 according to a specific embodiment of the present application will be described below with reference to the accompanying drawings.

1 to 6, the cleaning device 100 according to the embodiment of the present application includes a main body 10, a dust cup 11 connected to the main body 10, Handle 71, motor 40, power supply assembly 73, air inlet pipe 18, second filter 13 and third filter 15. In the present application, the cleaning device 100 adopts side air intake, so the inlet 108 is located on one side of the dust cup 11. The second filter 13 and the third filter 15 are respectively located in the front and rear of the motor 40 on the airflow path for filtering the airflow respectively. The third filter 15 can overlap with the motor 40 in space according to actual conditions. The dust cup 11, the motor 40 and the third filter 15 are arranged in sequence along the longitudinal axis of the dust cup 11, and the second filter 13 is located inside the dust cup 11. The power supply assembly 73 supports the entire cleaning device 100, the handle 71 is located between the motor 40 and the power supply assembly 73, the axis of the handle 71 does not pass through the motor 40, and the motor 40 is further rearward relative to the axis of the handle 71. The handheld vacuum cleaner has a relative distal end and a proximal end, the inlet 108 is located at the distal end, and the third filter 15 is located at the proximal end.

Further, in combination with Figure 2, the dust cup 11 includes a cup body 111 and a dust cup cover 112 for pouring dust, and a first filter 12 and a fourth filter 19 are provided in the cup body 111, wherein the first filter 12 is a filter mesh cover having a plurality of through holes on its surface for filtering dust with larger particle sizes, and the fourth filter 19 is a multi-cone cyclone, and the fourth filter 19 includes a plurality of small cones, which are arranged around the dust cup 11 and are located downstream of the first filter 12.

In conjunction with FIG7 , the cleaning device 100 further includes a scraping assembly, which includes a scraping portion 20, and the scraping portion 20 is used to move toward the dust cup cover 112 to squeeze the dust. The scraping portion 20 includes an extrusion piece 25 extending toward the inner wall of the dust cup 11 and adjacent to the inner wall of the dust cup 11, and the extrusion piece 25 extends close to the dust cup 11 in a direction perpendicular to the axis of the dust cup 11. With such a configuration, the extrusion piece 25 squeezes the dust, and the volume of the collected dust can be compressed, freeing up more space for dust separation or collection, avoiding excessive dust accumulation without dumping, resulting in excessive reduction in suction or separation efficiency, and after the dust is squeezed, the user does not need to frequently dump the dust in the dust cup 11, which can reduce the time of the cleaning process, reduce the labor of the customer, and improve the user experience.

In conjunction with FIG. 7 , in one embodiment, the extended end of the extrusion piece 25 can contact the inner wall of the dust cup 11 to scrape off the dust on the inner wall of the dust cup 11, and the edge of the extrusion piece 25 contacting the inner wall of the dust cup 11 can be a soft rubber strip structure or a bristle structure. On the other hand, by cleaning the inner wall of the dust cup 11, the dust cup 11 can be made cleaner and dust can be prevented from remaining on the inner wall.

In one embodiment, the scraping part 20 further includes a scraping member 22, which is disposed close to the first filter 12. The scraping member 22 may extend along the axial direction of the first filter 12, or may extend obliquely in a direction close to the first filter 12, so as to cooperate with the outer side of the first filter 12 to improve the scraping effect. When the scraping member 22 squeezes and scrapes the dust toward the dust cup cover 112, the dust floating on the surface of the first filter 12 may be cleaned up at the same time. The scraping member 22 may be at a certain distance from the first filter 12 but close enough. With such a configuration, the floating dust attached to the surface of the first filter 12 may be cleaned up to avoid docking on the first filter 12 and affecting the efficiency of airflow.

The scraping assembly includes an operating part 30 for controlling the movement of the scraping part 20, the operating part 30, a connecting rod 50 and a supporting part 23 fixed inside the main body 10. The scraping part 20 is located at one end of the first filter 12 close to the motor 40 in the initial position.

In conjunction with Figure 5, in one embodiment, three guide rods 21 are set between the support part 23 and the scraping part 20 to connect and transmit the movement of the operating part 30. One end of the connecting rod 50 is connected to the operating part 30, and the other end of the connecting rod 50 is connected to at least one of the guide rods 21, which is used to drive the scraping part 20 to move when the connecting rod 50 moves.

In conjunction with Figure 3, in one embodiment, the support portion 23 is arranged around the periphery of the motor housing 16 and can move along the motor housing 16 when the operating portion 30 is pushed. Since the extrusion member 25 is connected to the support portion 23 through the guide rod 21, when the support portion 23 moves along the motor housing 16, the scraping portion 20 moves in the same direction, so as to scrape off the dust on the periphery of the first filter 12 and collect and compress the dust in the dust pressing space 101.

In one embodiment, a spring 24 is sleeved on the guide rod 21. When scraping dust, the movement of the support portion 23 compresses the spring 24. When the action of scraping dust ends, the dust scraping portion 20 automatically resets due to the restoring force of the spring 24.

In conjunction with FIG. 1 , in one embodiment, the operating portion 30 is located below the dust cup 11 . This position can make it more convenient for the user to push and pull, making the pushing and pulling action smoother.

Specifically, during the cleaning process, the user can squeeze the dust multiple times to release more dust collection space, without the user having to dump the dust in the dust cup 11 multiple times.

During actual operation, in combination with Figures 1 and 2, the airflow path of the cleaning device 100 is as follows: the airflow enters the air inlet pipe 18 from the inlet 108, dust and air enter the dust cup 11 from the side of the dust cup 11, and the dust falls into the first dust collecting space after being filtered by the first filter 12. The airflow containing a small amount of dust continues to enter the fourth filter 19 for filtration, and the filtered fine dust falls into the second dust collecting space. The airflow continues to enter the second filter 13 for filtration and flows toward the motor 40, and finally passes through the third filter 15 and is discharged from the outlet.

Specifically, dust and air enter the device from the inlet 108 and enter the dust cup 11 tangentially along the air duct. Under the action of centrifugal force, dust and debris rotate down along the wall of the dust cup 11 to the first dust collecting space of the dust cup 11. Part of the dust passes through the first filter 12 and enters the fourth filter 19. Similarly, under the action of centrifugal force, the dust rotates down along the inner wall of the fourth filter 19 to the second dust collecting space at the bottom, and the gas enters the second filter 13 through the porous air passage at the dust-gas separation port, then enters the motor 40, and is filtered by the third filter 15 before being discharged. By setting up two cyclone filtrations and the fourth filter 19 adopting a multi-cone cyclone mechanism, the separation efficiency of dust and air can be greatly increased, the number of times the filter is cleaned can be reduced, and the service life of the filter can be extended.

In conjunction with Figure 2, the second filter 13 is located inside the first filter 12. The vacuum cleaner is provided with the second filter 13. The pre-filter 13 is provided with a handle 131. The handle 131 is used to take out the pre-filter 13 along the longitudinal axis of the dust cup 11. The handle 131 is provided near the dust cup cover 112. The pre-filter 13 is removable in a direction away from the dust cup cover 112. The third filter 15 can be disassembled backwards. Such an arrangement can facilitate the cleaning of the second filter 13 and the third filter 15. The second filter 13 is coaxially arranged with the first filter 12, and the scraping part 20 moves along the axial direction of the second filter 13. More specifically, the second filter 13 includes filter cotton and a filter bracket. After being filtered by the filter cotton, the airflow enters the interior through a number of through holes on the filter bracket and flows from the internal channel toward the motor 40.

As stated above, in order to allow the second filter 13 to be quickly disassembled and cleaned, as shown in Figure 2, the second filter 13 is located in the middle of the dust cup 11, and is connected to the fan assembly through a sealing ring at the top. The gas after dust and gas separation enters the pre-filter 13 through the porous air passage and then enters the motor 40 before being discharged. Usually, there will be a small amount of fine ash attached to the outer wall of the second filter 13. When the pre-filter 13 needs to be cleaned, just hold the handle 131 at the opening at the bottom of the dust cup 11 and pull it out. After cleaning, it can be assembled in the same way. In this way, the second filter 13 can be quickly cleaned or replaced without disassembling any other components, which provides convenience for users.

As shown in FIGS. 8 to 15 , according to the cleaning device 100 in the embodiment of the present application, the cleaning device 100 can be used to suck dust to clean the environment. The cleaning device 100 may include a main body 10 , a driving assembly, a rear cover 80 , and a display assembly 90 .

Among them, the main body 10 has an air flow channel 110, and at least a part of the driving component is arranged in the air flow channel 110 to drive the air flow; the rear cover 80 is detachably covered at the outlet of the air flow channel 110, and the display component 90 is installed on the driving component and separated from the rear cover 80. The display component 90 is configured to display information toward the outside of the rear cover 80. In other words, it can be used to display the operating information or other information of the cleaning device 100. This arrangement can improve the working stability of the display component 90 and avoid damage to the display component 90.

Specifically, the display component 90 is installed on the drive component, and the drive component is arranged in the air flow channel 110. When the rear cover 80 is connected to the main body 10, the rear cover 80 can cover the outlet of the air flow channel 110 to encapsulate the drive component and the display component 90 on the main body 10. The rear cover 80 can protect the structural components in the cleaning device 100, so that the drive component can be stably connected to the main body 10. At the same time, the display component 90 can display information toward the outside of the rear cover 80, and the rear cover 80 can facilitate the display component 90 to display information to the outside. For example, at least a portion of the rear cover 80 can be constructed with an opening 81, and the display component 90 can display information to the outside through the opening 81. For example, at least a portion of the rear cover 80 can be constructed as a transparent structure, and the display component 90 can display information to the outside through the transparent structure to improve user convenience. When the third filter 15 needs to be cleaned, the back cover 80 can be removed from the main body 10. At this time, the display component 90 installed on the driving component can be separated from the back cover 80 to prevent the display component 90 from falling and being damaged when the back cover 80 is removed. In addition, the display component 90 installed on the driving component can arrange and hide the circuits between the display component 90 and the driving component to ensure the working stability of the display component 90.

In addition, at least a portion of the driving assembly is disposed in the air flow channel 110 , so that the cleaning device 100 has a more compact structure and a smaller volume.

Therefore, according to the cleaning device 100 in the embodiment of the present application, the working stability of the display assembly 90 can be improved and damage to the display assembly 90 can be avoided.

As shown in FIG. 2 , in some embodiments of the present application, the rear cover 80 can be configured to be detachable from the main body 10 independently of the display assembly 90, that is, the rear cover 80 can be detached from the main body 10 independently, and the display assembly 90 does not need to be detached from the main body 10 when the rear cover 80 is detached from the main body 10. This arrangement can improve the working stability of the display assembly 90, avoid damage to the display assembly 90, and facilitate cleaning of the third filter 15.

Specifically, after the cleaning device 100 has been used for a period of time, dust and other garbage carried by the airflow will accumulate on the third filter 15. The user can remove the back cover 80 from the main body 10 separately relative to the display component 90 to repair and maintain the interior of the cleaning device 100. At the same time, the display component 90 can be stably installed on the driving component to prevent the display component 90 from falling and being damaged during disassembly and assembly of the back cover, and can also maintain the electrical connection between the display component 90 and the main body 10 to ensure the normal operation of the display component 90.

In some embodiments of the present application, the driving assembly may include a motor 40, and the display assembly 90 may be installed on the air outlet side of the motor 40. It can be understood that in the cleaning device 100, the motor 40 may be installed in the air flow channel 110, the air inlet side of the motor 40 may correspond to the inlet 108 of the air flow channel 110, the air outlet side of the motor 40 may correspond to the outlet 109 of the air flow channel 110, and the rear cover 80 may cover the air flow channel 110. At the outlet 109, therefore, the display component 90 can be installed on the air outlet side of the motor 40 so that the display component 90 can display information toward the outside of the rear cover 80, making it convenient for users to obtain the working information of the device.

Furthermore, the display component 90 can be installed at the end of the motor 40 close to the outlet 109. In other words, the display component 90 can be close to the outlet 109 of the air flow channel 110 so that the display component 90 can display information toward the outside of the rear cover 80.

Alternatively, a mounting bracket 151 may be provided on the air outlet side of the motor 40, and the display component 90 may be installed on the mounting bracket 151. This arrangement can prevent the display component 90 from blocking the air outlet side of the motor 40, making it convenient for the motor 40 to drive the airflow through the airflow channel 110 while the display component 90 displays information toward the outside of the rear cover 80.

In some embodiments of the present application, the driving assembly may further include a third filter 15 .

The third filter 15 may be disposed on the air outlet side of the motor 40 and located at the outlet 109 of the air flow channel 110 , and the display component 90 may be mounted on the third filter 15 to realize the dust removal function of the cleaning device 100 .

Specifically, during the operation of the cleaning device 100, the motor 40 can drive the airflow to pass through the inlet 108 of the airflow channel 110, the airflow channel 110 and the outlet 109 of the airflow channel 110 in sequence, and be filtered by the third filter 15 at the outlet 109, so that dust and other garbage entrained in the airflow can be filtered out by the third filter 15, thereby realizing the cleaning function of the cleaning device 100.

In some embodiments of the present application, at least a portion of the third filter 15 can extend out of the outlet 109, and the rear cover 80 is disposed on the outside of the third filter 15. It can be understood that the display component 90 is installed on the outside of the third filter 15, and the display component 90 can be located on the air outlet side of the motor 40. In other words, the display component 90 can face the outlet 109 of the air flow channel 110. At this time, at least a portion of the third filter 15 can be extended out of the outlet 109, so that the display component 90 can better display information toward the outside of the rear cover 80, thereby improving user convenience.

As shown in Figures 8 to 12, in some embodiments of the present application, the main body 10 can extend in the front-to-back direction, and the outlet 109 of the airflow channel 110 can be arranged at the rear end of the main body 10, and the display component 90 is arranged on the motor 40 and displays information toward the rear of the main body 10. This arrangement can facilitate the user to obtain the working information of the cleaning device 100, thereby improving the user's convenience.

Among them, the inlet 108 of the airflow channel 110 can be set at the front end of the main body 10. In other words, the airflow enters the inlet 108 of the airflow channel 110 from the front end of the main body 10, and after passing through the airflow channel 110, it is discharged from the outlet 109 set at the rear end of the main body 10; or, the main body 10 has a side wall extending in the front-to-back direction, and the inlet 108 of the airflow channel 110 can be set on the side wall of the main body 10. After entering the airflow channel 110, it can flow along the tangential direction of the side wall of the main body 10 to filter part of the dust for the first time through cyclone separation, and then it can be discharged from the outlet 109 and filtered for the second time through the third filter 15 to achieve dust removal of the cleaning device 100.

For example, in the front-to-back direction, the inlet 108 of the airflow channel 110 is arranged at the front end of the main body 10, and the outlet 109 of the airflow channel 110 is arranged at the rear end of the main body 10. It can be understood that when the user uses the cleaning device 100, the front end of the main body 10, that is, the inlet 108 of the airflow channel 110 can be aligned with the area to be cleaned, and the airflow driving action of the motor 40 can be used to complete the cleaning of the cleaning area by the cleaning device 100. In addition, the outlet 109 of the airflow channel 110 can be arranged at the rear end of the main body 10, and the display component 90 can be arranged on the motor 40 so that the display component 90 can be facing the user himself, so that when the user uses the cleaning device 100, the user can obtain the operating parameters of the cleaning device 100 through the display component 90, and can also control the operation of the cleaning device 100 through the display component 90, thereby improving the user's convenience.

As shown in Figure 14, in some embodiments of the present application, a display area may be provided on the back cover 80, wherein the display area has an opening 81, a transparent area or a translucent area, and when the back cover 80 is installed on the main body 10, the display area may be opposite to the display component 90 to facilitate the display component 90 to display information, thereby improving user convenience.

Specifically, the third filter 15 can be arranged on the rear side of the main body 10. When the rear cover 80 is installed on the main body 10, the rear cover 80 can be arranged on the outside of the third filter 15 to encapsulate the third filter 15 on the main body 10 to protect the third filter 15. In addition, a display area is provided on the rear cover 80. When the rear cover 80 is installed on the main body 10, the display area can be opposite to the display component 90 on the third filter 15, so that the display component 90 can display information toward the rear of the main body 10 through the opening 81, so that the user can obtain the operating parameters of the cleaning device 100 when using the cleaning device 100.

As shown in Figures 9 to 12, in some embodiments of the present application, the display component 90 may be arranged on the inside of the display area, at least a portion of it may be embedded in the display area or extend out of the display area. It can be understood that the display component 90 is installed on the third filter 15. When the back cover 80 is installed at the rear end of the main body 10, the display component 90 may be arranged on the inside of the display area, and the display area may be a transparent area or a semi-transparent area, so that the user can obtain the information on the display component 90 through the display area; or, at least a portion of the display component 90 may be embedded in the opening 81 of the display area to position the display component 90 through the opening 81, and the portion of the display component 90 embedded in the opening 81 may display information, that is, through the opening 81, the display component 90 may display information to the outside to improve the user's convenience. In addition, indirectly, the back cover 80 may be provided to the third filter 15. The three filters 15 serve as positioning; alternatively, at least a portion of the display assembly 90 may extend out of the display area to display information toward the rear side of the cleaning device 100, thereby facilitating the user to obtain operating parameters of the cleaning device 100 and improving user convenience.

In other embodiments of the present application, the display surface of the display assembly 90 may be flush with the rear side surface of the rear cover 80. This arrangement can make the rear side structure of the cleaning device 100 flat, making it easier for the user to clean.

In some other embodiments of the present application, at least a portion of the display component 90 is embedded in the opening 81, so that the display component 90 can be positioned and it can be ensured that the display component 90 can stably display information. At the same time, the display surface of the display component 90 is flush with the rear side surface of the rear cover 80, so that the rear side structure of the cleaning device 100 is flat, which is convenient for users to clean.

As shown in Figures 8 to 12, in some embodiments of the present application, the third filter 15 can be installed at the end of the main body 10. In other words, in combination with the aforementioned embodiments, the third filter 15 can be installed at the rear end of the main body 10 to filter the airflow passing through the outlet 109 of the airflow channel 110 to achieve the dust removal effect of the cleaning device 100.

Furthermore, at least a portion of the third filter 15 can be embedded in the main body 10. This arrangement can increase the contact area between the third filter 15 and the main body 10, thereby increasing the connection strength between the third filter 15 and the main body 10 to ensure that the third filter 15 can work normally.

Furthermore, the rear cover 80 can be connected to the main body 10 and position the third filter 15; specifically, the rear cover 80 includes a peripheral wall extending in the front-to-back direction, and has a first end and a second end relative to each other, wherein the first end of the rear cover 80 is open, and the rear cover 80 can be installed on the main body 10 through the first end, and is arranged on the outside of the third filter 15 to achieve the installation of the cleaning device 100 shell, so as to protect the third filter 15 and the display component 90. In addition, a closed surface is provided on the second end of the rear cover 80, and an opening 81 can be provided on the closed surface, so that when the rear cover 80 is installed on the main body 10, the display component 90 can be opposite to the opening 81, so that the display component 90 can display information toward the rear of the main body 10, so that the user can obtain the operating parameters of the cleaning device 100, and an abutment portion can also be provided on the closed surface, and the abutment portion can protrude forward. When the rear cover 80 is installed on the main body 10, the abutment portion can abut on the rear side of the third filter 15 to position the third filter 15 and ensure that the first positioning component can work normally.

As shown in Figure 13, in some embodiments of the present application, the third filter 15 can be installed on the outside of the motor 40, and the third filter 15 partially overlaps with the motor 40 in the projection in a predetermined direction, and the predetermined direction is perpendicular to the axis of the motor 40. It can be understood that at least part of the motor 40 can be mounted on the inner side of the third filter 15 to reduce the volume of the assembly of the motor 40 and the third filter 15, improve the integration, and realize the miniaturization of the cleaning device 100.

In some embodiments of the present application, the third filter 15 is detachably mounted on the main body 10. It can be understood that the third filter 15 and the main body 10 are split structures. Such an arrangement can facilitate the processing and manufacturing of the cleaning device 100 and reduce the complexity of the manufacturing process.

Of course, the third filter 15 and the main body 10 may be an integrated structure, so as to enhance the structural strength of the cleaning device 100 .

In addition, in combination with the above-mentioned embodiment, the rear cover 80 and the third filter 15 are detachably mounted on the main body 10, that is, by disassembling and assembling the third filter 15 and the main body 10, the rear cover 80 and the third filter 15 can be simultaneously disassembled and assembled on the main body 10.

As shown in FIG. 9 and FIG. 15 , in some embodiments of the present application, the third filter 15 may include a bracket 151 and a filter element 152 .

Among them, the bracket 151 has a hollow structure 1511, the bracket 151 is connected to the main body 10, the hollow structure 1511 is connected to the air flow channel 110, and the filter 152 shields the hollow structure 1511. Therefore, the air flow in the air flow channel 110 can be filtered to achieve dust removal and display functions of the cleaning device 100.

Specifically, the third filter 15 is installed on the outside of the motor 40. When the cleaning device 100 is working, the motor 40 can drive the airflow in the airflow channel 110 to flow to the hollow structure 1511. At this time, the filter element 152 can cover the hollow structure 1511 on the bracket 151. When the airflow channel 110 has the hollow structure 1511, the filter element 152 can filter the airflow to filter out dust and other garbage entrained in the airflow, thereby realizing the dust removal function of the cleaning device 100.

Furthermore, the bracket 151 has a first end and a second end relative to each other, the hollow structure 1511 is arranged between the first end and the second end of the bracket 151, the first end of the bracket 151 is connected to the main body 10, and the display component 90 is arranged at the second end of the bracket 151 to realize the dust removal function of the cleaning device 100.

Specifically, the first end and the second end are opposite to each other along the front-to-back direction (wherein the front-to-back direction is the same as the direction of the axis), and the second end is arranged rearward relative to the first end. At this time, the display component 90 can be arranged on the second end of the bracket 151. In other words, the display component 90 is arranged on the rear side of the third filter 15 so that the display component 90 can face backward to display the operating parameters of the cleaning device 100 to the user, thereby improving the convenience of user use.

In addition, a hollow structure 1511 is provided between the first end and the second end, and the hollow structure 1511 can be perpendicular to the predetermined direction and can be aligned with the airflow. The channel 110 is connected so that the airflow of the airflow channel 110 can be discharged in a predetermined direction. It can be understood that the display component 90 is installed at the second end and displays information rearward along the axial direction of the motor 40. At the same time, the airflow can be discharged in a predetermined direction through the hollow structure 1511, and the filter element 152 arranged on the hollow structure 1511 can filter the airflow. Therefore, the bracket 151 can guide the airflow to be discharged and filtered while realizing the information display of the display component 90. Compared with reserving installation space separately for the display component 90 and the filter element 152, the present application improves the space utilization rate of the cleaning device 100.

As shown in Figure 15, in some embodiments of the present application, the first end of the bracket 151 may be provided with a positioning ring 1512, and the second end may be provided with an end cover 1513. The positioning ring 1512 and the end cover 1513 are connected by a connecting rib 1514 to form a hollow structure 1511 between the positioning ring 1512 and the end cover 1513.

Therefore, the installation strength of the display assembly 90 can be improved by the annular rib 15131 .

Specifically, an annular rib 15131 is provided on the end cover 1513, and the annular rib 15131 extends along the axial direction of the motor 40 to protrude relative to the surface of the end cover 1513, thereby forming a groove 15132. At this time, the display assembly 90 can be installed in the groove 15132 to achieve the installation of the display assembly 90. In addition, when the rear cover 80 is installed on the main body 10, part of the structure of the rear cover 80 can abut against the end cover 1513 to position the bracket 151 and improve the installation strength of the bracket 151.

Furthermore, an opening 81 is provided on the rear cover 80, and the annular rib 15131 is embedded in the opening 81, so that the display component 90 installed in the groove 15132 can display information to the rear side of the cleaning device 100 through the opening 81, thereby improving the convenience for users to obtain operating information.

In some specific examples of the present application, the cleaning device 100 has a bracket 151, the display screen (i.e., the display assembly 90) is mounted at the end of the bracket 151 and faces the rear, and the rear cover 80 is provided with a through hole or a transparent structure at a position corresponding to the display screen, so that the content of the display screen can be observed through the rear cover. In this embodiment, the rear cover is provided with a through hole, and of course in other embodiments, a transparent structure can be used to see through the content displayed on the display screen.

In some specific examples of the present application, the motor post-filter (i.e., the third filter 15) may include two parts. Since the end of the bracket 151 is used to install the display screen, there is still space on both sides. Therefore, through the structural design of the bracket 151 and the two-part post-filter structural design, the structure of the bracket 151 and its internal space can be fully utilized, and the structural layout can be reasonably arranged, so that the overall structure of the vacuum cleaner is more compact, which is conducive to the miniaturization of the machine.

In some specific examples of the present application, a filter assembly may be provided in the main body 10, and the filter assembly includes a first filter 12, a fourth filter 19 and a motor pre-filter (i.e., a second filter 13), wherein a first dust collecting space is provided between the first filter 12 and the fourth filter 19, and a second dust collecting space is provided between the fourth filter 19 and the motor pre-filter, and the first dust collecting space and the second dust collecting space can be used to collect dust and other garbage filtered out from the airflow.

The airflow path of the cleaning device 100 can be as follows: the airflow enters the air inlet duct from the inlet 108, dust and air enter the main body 10 from the side of the main body 10, the dust falls into the first dust collecting space after being filtered by the first filter 12, the airflow containing a small amount of dust continues to enter the fourth filter 19 for filtration, the filtered fine dust falls into the second dust collecting space, the airflow continues to enter the motor pre-filter for filtration and then flows toward the motor, and finally passes through the motor post-filter (i.e., the third filter 15) and is discharged from the outlet 109.

Specifically, dust and air enter from the suction port 108, and enter the main body 10 tangentially through the inlet 108. Under the action of centrifugal force, dust and debris rotate down along the side wall of the main body 10 to the first dust collecting space of the main body 10. A flange that forms a certain angle with the horizontal direction (wherein the horizontal direction is the same as the direction of the axis) is provided below the filter screen cover (i.e., the first filter 12). The lower flange of the filter screen cover (i.e., the first filter 12) can prevent dust that enters the bottom due to centrifugal force from entering the multi-cone cyclone (i.e., the fourth filter 19) again, thereby effectively reducing the total amount of dust that enters the multi-cone cyclone (i.e., the fourth filter 19). A portion of the dust passes through the filter screen cover (i.e., the first filter 12) and enters the multi-cone cyclone (i.e., the fourth filter 19). Cone cyclone (i.e., the fourth filter 19); similarly, under the action of centrifugal force, dust swirls down the wall of the multi-cone cyclone (i.e., the fourth filter 19) to the second dust collecting space at the bottom, and the gas enters the motor pre-filter through the porous air passage at the dust-gas separation port, then enters the motor, and is filtered by the motor post-filter before being discharged. In this case, two cyclone filters are set up, and the secondary filtration uses a multi-cone cyclone mechanism, which can greatly increase the separation efficiency of dust and air, reduce the number of times the filter is cleaned, and extend the service life of the filter.

In this case, by setting up a motor pre-filter and a motor post-filter, filtering is arranged at both the motor air inlet and outlet ends to improve the separation efficiency.

In this case, the display screen is arranged on the bracket 151, and the motor post-filter is installed by utilizing the structure of the bracket 151, so that the space is reasonably utilized, the structure of the whole machine is more compact, and the display screen is prevented from falling and being damaged.

The handheld vacuum cleaner (i.e., the cleaning device 100) includes a main body 10, a dust cup connected to the main body 10, a handle, a motor, a battery, an air inlet, a motor pre-filter, and a motor post-filter (i.e., a third filter 15). The handheld vacuum cleaner of the present application can adopt side air intake, so the air inlet is located on the side of the dust cup. The motor pre-filter and the motor post-filter are respectively located at the front and rear of the motor on the airflow path for filtering the airflow respectively. The motor pre-filter is located in the dust cup and at least partially located in the primary filter.

The post-motor filter can overlap with the motor in space according to actual conditions. The dust cup, motor, and post-motor filter are arranged in sequence along the longitudinal axis of the dust cup. The battery supports the entire handheld vacuum cleaner, and the handle is located between the motor and the battery. The axis of the handle does not pass through the motor, and the motor is further back relative to the axis of the handle. The handheld vacuum cleaner has a relative distal end and a proximal end, the air inlet is located at the distal end, and the post-motor filter is located at the proximal end.

The dust cup includes a cup body, a dust cup cover for pouring dust, a first filter and a fourth filter 19 arranged in the cup body, wherein the first filter 12 is a filter screen with a plurality of through holes on the surface for filtering dust with larger particle size, and the fourth filter 19 is a multi-cone cyclone, which includes a plurality of small cones, which are arranged around the dust cup and located downstream of the first filter 12. The dust cup is also provided with an unlocking button for unlocking the dust cup cover.

The motor pre-filter is located inside the first filter 12. The vacuum cleaner is provided with a motor pre-filter handle for taking out the pre-filter along the longitudinal axis of the dust cup. The pre-filter handle is located near the ash dump cover, and the pre-filter is disassembled in the direction away from the dust cup cover. The motor post-filter can be disassembled from the rear, so that the motor pre-filter and the motor post-filter can be cleaned conveniently. The motor pre-filter is coaxially arranged with the first filter 12. The motor pre-filter includes a filter bracket 151 and filter cotton arranged on the filter bracket 151. After being filtered by the filter cotton, the airflow enters the interior through a number of through holes on the filter bracket 151 and flows from the internal channel toward the motor.

As stated above, in order to allow the motor pre-filter to be quickly disassembled and cleaned, the pre-filter is designed with a quick disassembly function (without removing the entire dust cup). The motor pre-filter is located in the middle of the dust cup and is connected to the fan assembly through a sealing ring on the top. The gas after dust and gas separation enters the pre-filter through the porous air channel and then enters the motor and is discharged. Usually, there will be a small amount of fine ash attached to the outer wall of the motor pre-filter. When the pre-filter needs to be cleaned, just hold the handle of the filter at the opening at the bottom of the dust cup and pull it out. After cleaning, it can be assembled in the same way. In this way, the motor pre-filter can be quickly cleaned or replaced without disassembling any other components, greatly improving user convenience and satisfaction.
