It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 3, a vacuum cleaner 100 according to a first embodiment of the present invention includes an airflow inlet 101 for holding, a handle assembly 20, a dust cup assembly 40, a motor assembly 140 for providing power, and the airflow inlet 101, wherein the motor assembly 140 is located between the airflow inlet and the dust cup assembly 40 for generating negative pressure for dust collection, and the airflow inlet 101 is used for introducing airflow containing dust into the dust cup assembly 40. The dirt cup assembly 40 is disposed in an air duct formed between the airflow inlet 101 and the air outlet of the cleaner. The motor assembly 140 includes a motor, which may be a brush motor or a brushless motor. The motor assembly further comprises a stationary impeller and a wind guiding cavity. The cleaner further comprises a battery unit 150, the battery unit 150 being provided below the motor assembly 140. The airflow inlet 101 is disposed at the front end of the dirt cup assembly 40 and the motor assembly 140 is disposed at the rear end of the dirt cup assembly. I.e., the dirt cup assembly, is disposed between the airflow inlet 101 and the motor assembly 140. The motor assembly 140 communicates with an airflow passage outlet 115 described below and a suction cleaner air outlet, and the airflow filtered by the filter 110 enters the motor assembly 140 to cool the motor, and finally, the hot air is discharged through the suction cleaner air outlet.

As shown in fig. 1 and 3, the dirt cup assembly 40 includes a cup 41, a cyclone 120 disposed within the cup 41, a filter 110 disposed within the cyclone 120, and a dirt collection chamber 130. The filter 110 is a water-resistant filter, which in one embodiment is a water-resistant HEPA unit.

As shown in fig. 1, the cyclone separator 120 includes a cylindrical main body 122, the main body 122 circumferentially surrounds the side of the filter, and the airflow entering from the airflow inlet of the cleaner is guided by the main body 122 to form a circulating cyclone. The utility model discloses a dust catcher is wet and dry dual-purpose dust catcher, and wet and dry dual-purpose dust catcher will require than dry-type dust catcher's sea handkerchief specific surface area to the specific surface area requirement of sea handkerchief unit and require that the specific surface area of sea handkerchief unit is big promptly, because general waterproof sea handkerchief needs the coating film, so dust absorption area can diminish, so in order to reach the performance requirement of dust catcher, need increase sea handkerchief area, the utility model discloses a filter 110 that will possess waterproof function sets up in cyclone 120's inside, and filter 110's extending direction is unanimous with cyclone 120's extending direction, has increased the shape surface area of filter for the dust catcher can satisfy wet and dry user demand.

In one embodiment, the body portion 122 is a spiral channel that spirals downward around the filter. In one embodiment, the height of the body portion 122 is less than the height of the filter 110, such that the sides of the filter 110 can be circumferentially surrounded only within a limited height range, such as circumferentially surrounding a middle section of the filter 110, leaving one section of the filter 110 above and one section below (i.e., not surrounded by the body portion 122).

As shown in fig. 1 and 3, the filter 110 and the bottom of the body portion 122 are located within the dirt collection chamber 130.

In the vacuum cleaner, the sucked air flow enters the main body 122 from the air flow inlet 101, forms a cyclone downwardly surrounding the filter 110 under the guidance of the main body 122, and enters the dust collecting chamber 130. In this process, the larger dust particles (and other larger foreign materials, liquids, etc.) fall toward the bottom of the dust collecting chamber 130 due to their own weight. And the air flow also enters the interior of the filter 110 due to the negative pressure. During the passage through the filter 110, the remaining smaller dust particles and minute liquid droplets are blocked by the filter 110. Since the large dust particles and liquid are separated into the dust collecting chamber 130 by the cyclone 120, the filter 110 is less burdened and can be clogged over a longer period of time.

In the vacuum cleaner 100, the cyclone separator 120 is installed on the dirt cup assembly 40, so that the dirt can be prevented from being jammed in the dirt cup assembly 40, and the dust suction capability of the vacuum cleaner can be prevented from being reduced.

The cyclone separator 120 may be sleeved on the filter 110 of the vacuum cleaner to form the dust cup assembly 40 together with the filter 110 for filtering dust, and the cyclone separator 120 may perform preliminary filtering on the airflow entering the filter 110 and prevent dust from being accumulated on the filter 110.

In one embodiment, the cyclone separator 120 is a single stage cyclone configuration. In other embodiments, the cyclone separator 120 may have a multi-stage cyclone structure, that is, in the flowing direction of the airflow, the cyclone chamber for cyclone separation includes multiple stages of cyclone chambers connected in sequence, so that the airflow entering the main body 122 may pass through the multiple stages of cyclone chambers in sequence for multiple dust-air separations, thereby improving the dust removal effect.

In one embodiment, the cyclone separator 120 circumferentially surrounds the sides of the filter 110. In one embodiment, the cyclone 120 has a filtering hole 213 formed at a side surface thereof and an air inlet formed at a bottom thereof. The aperture of the filter holes 213 should be significantly larger than the particle size of the particles that the hypa body 114 can pass through, and it is understood that the filter hole size shown in the drawing is designed with the purpose of being directly recognizable to the human eye and does not represent the actual size of the filter hole.

As shown in fig. 3 and 4, the filter 110 includes a supporter 112 and a hypaete body 114 fixed to the supporter 112. The filter 110 is formed with an air flow passage outlet 115, and is also formed with a passage 113 extending downward from the air flow passage outlet 115. In one embodiment, the airflow channel outlet 115 is disposed at the top of the filter 110, and the channel 113 is a reverse cone with a large top and a small bottom.

The HEPA body 114 is columnar and is surrounded by laminated waterproof HEPA to form a hollow column, the pleat width is 2-20 mm, and the pleat width is the width of the laminated part of the waterproof HEPA; and/or, the area of the lateral surface of the pillar of the HEPA body 114 is 15000-; and/or the expansion area of the HEPA body 114 is 80000-120000 square millimeters. Preferably, the pleat width is 10 mm. In one embodiment, baghouse 130 has a volume of 0.6-1 liters.

The HEPA body 114 is waterproof HEPA, and the waterproof HEPA can be obtained by forming a waterproof film on the surface of the HEPA body 114. In one embodiment, a waterproof membrane covers the outer surface of the HEPA body 114. The HEPA body 114 is HEPA reaching the H12 grade standard or HEPA reaching the H13 grade standard.

The utility model discloses a set up cyclone 120, can make the air current earlier through cyclone 120's filtration, then reentrant sea handkerchief body 114 is filtered once more by sea handkerchief body 114, can further improve the jam condition of sea handkerchief body 114, improves sea handkerchief body 114's life.

As shown in fig. 3, 5 and 6, the cyclone separator 120 includes a flow guide structure 211 for guiding flow, two ends of the main body 122 are respectively provided with an air inlet and an air outlet which are oppositely communicated and respectively located at two ends of the main body 122, a filter cavity 210 is arranged between the cyclone separator 120 and the filter 110, and the flow guide structure 211 is arranged at the air inlet and forms the filter cavity 210 together with the main body 122. The flow guiding structure 211 comprises a plurality of guiding ribs 127 arranged at intervals along the circumferential direction, and an air flow channel 212 is formed between adjacent guiding ribs 127. The gas flow passage 212 communicates with the filter cavity 210. The air inlet of the filter is the space between the adjacent guide ribs 127.

In one embodiment, the extending direction of the guide rib 127 from the top to the bottom is the same as the rotating direction of the main body 122 around the cyclone. By combining the filter 110 with the flow guide structure, the flow guide structure can block dust on one hand, so that excessive dust is prevented from rising to enter the water handkerchief unit 110, and the service life of the filter 110 is prolonged; on the other hand, after the dust collector sucks a large amount of liquid, the water blocked by the water HEPA unit 110 after the dust collector stops falls down due to the action of gravity, and finally falls down through an air flow channel between the guide ribs 127 of the flow guide structure and is collected by the dust cup assembly.

On the other hand, when the vacuum cleaner 100 provided with the cyclone separator 42 stops operating, due to the arrangement of the air flow passage 4222, dust on the filter 44 engaged with the cyclone separator 42 can fall out of the filter cavity 426 in time through the air flow passage 4222 along the guide rib 4224 by gravity, thereby preventing the dust from remaining on the flow guide structure 422 and then reattaching to the filter 44 by gravity due to the deflection of the vacuum cleaner 100. Thus, the service life of the dirt cup assembly 40 is increased, and the cost of the vacuum cleaner 100 provided with the cyclone separator 42 is reduced

Thus, the dusty airflow enters the dirt cup assembly 40 from the airflow inlet, the airflow is rotated and separated around the cyclone separator 120, a part of the airflow passes through the filter holes 213 to reach the filter cavity 210 of the cyclone separator 120, another part of the airflow enters the filter cavity 210 of the cyclone separator 120 from the bottom of the dirt cup assembly 40, and the airflow entering the filter cavity 210 flows upwards after being secondarily filtered by the filter 110 in the filter cavity 210 and is discharged to the motor assembly 140.

The dust collector can prevent dust from blocking the dust cup component 40 because the dust cup component 40 is provided with the cyclone separator 120, avoid the reduction of the dust collecting capability of the dust collector,

as shown in FIG. 1, the bottom of the dust collecting chamber 130 is opened with a dust pouring port, and the dust collector includes a dust pouring cover 132. The dust dumping cover 132 is opened when the cleaner is in a horizontal state, so that the dust dumping port is communicated with the expanded dust box 160; when the cleaner is in a hand-held type, the dust discharge opening is closed by the dust discharge cover 132.

As shown in figure 1, the dust collector also comprises a dust dumping cover release button. The front end of the dust dumping cover 132 is rotatably connected with the bottom of the front end of the dust collecting chamber 130, and the rear end of the dust dumping cover 132 is clamped with the bottom of the rear end of the dust collecting chamber 130. When the dust dumping cover release button is pressed, the button releases the clamping state of the dust dumping cover 132 and the dust collecting chamber 130, and the rear end of the dust dumping cover 132 naturally falls due to gravity, so that the dust dumping port is communicated with the expanded dust box 160. In one embodiment, the ash cover release button is provided on the vacuum cleaner 100. The main body and the dust expansion box 160 are engaged with each other by the engaging portion 134, and when the main body release button is pressed, the main body release button releases the engagement state between the engaging portion 134 and the dust expansion box 160, and the box expansion box 160 is separated from the main body.

As shown in FIG. 1, in one embodiment, the bottom of the support frame 112 is a wind-blocking structure, i.e., the bottom of the support frame 112 is not ventilated. Thus, an air stream rising from the bottom of the filter 110 (e.g., an air stream entering from the filter inlet) is blocked by the bottom of the shelf 112, and dust particles entrained in the air stream fall downward, and the air stream bypasses the bottom of the shelf 112 and continues to rise around the bottom of the shelf 112 and into the filter from the side of the filter 110.

When the vacuum cleaner provided with the cyclone separator 120 stops operating, due to the arrangement of the airflow channel 212, dust on the filter 110 engaged with the cyclone separator 120 can fall out of the filter chamber 210 in time through the airflow channel 212 along the guide rib 127 under the action of gravity, thereby preventing the dust from remaining on the flow guide structure 211 and then reattaching to the filter 110 under the action of gravity due to the deflection of the vacuum cleaner. Thus, the lifetime of the dirt cup assembly 40 is increased, and the cost of the vacuum cleaner provided with the cyclone 120 is reduced.

As shown in fig. 3-6, the main body 122 has a substantially circular cross-section, and an inner diameter gradually increases from the flow guide 211 to a side away from the flow guide 211. The body 122 has a plurality of filter holes 213 formed therethrough, and the filter holes 213 communicate the filter chamber 210 with the outside. Thus, when the airflow carrying dust passes through the filter holes 213, the airflow passes through the filter holes 213 and enters the filter cavity 210, and part of the dust can be blocked by the region of the main body 122 where the filter holes 213 are not formed, so that the pre-filtering of the dry and wet dust-containing airflow is completed, only the airflow with less dust content passes through the filter 110, the blockage of the filter 110 is avoided, the service life of the filter 110 is prolonged, and the dust removal performance is improved.

Further, the cyclone separator 120 further comprises a flow guide assembly 4244, the flow guide assembly 4244 is arranged at one end of the main body portion 122, which is far away from the flow guide structure 211, the flow guide assembly 4244 forms a spiral flow guide channel which bypasses the central axis of the filter cavity 210 to guide the airflow so that the airflow surrounds the main body portion 122, and then the airflow enters the filter cavity 210 through the plurality of filter holes 213 which are circumferentially arranged on the main body portion 122, so that the air intake efficiency of the cyclone separator 120 is improved.

As shown in fig. 4-6 and 9, the deflector structure 211 includes a cylindrical wind deflector 125. Each guide rib 127 comprises a head portion 4224a and a root portion 4224b which are oppositely arranged, the head portion 4224a is connected to the inner wall of the main body portion 122, and the root portions 4224b of the plurality of guide ribs 127 are converged on the outer periphery of the wind deflector 125 from the main body portion 122 to the central axis of the filter cavity 210 to form a radial structure.

As shown in fig. 9, the guiding rib 127 further includes a first side 4224c and a second side 4224d connecting the head 4224a and the root 4224b and disposed opposite to each other. The first side 4224c is disposed at a side close to the air inlet, the second side 4224d is disposed at a side far from the air inlet, and orthographic projections of the first side 4224c and the second side 4224d on a plane perpendicular to the central axis of the filter cavity 210 are not coincident. That is, the guide rib 127 extends obliquely from the first side 4224c to the second side 4224d, rather than vertically in a direction parallel to the central axis of the filter cavity 210 (i.e., the projection of the first side 4224c and the second side 4224d onto a plane perpendicular to the central axis of the filter cavity 210 coincide).

As shown in fig. 9, the dust falling on the flow guiding structure 211 can slide from the end of the first side 4224c to the end of the second side 4224d under the action of gravity, and finally fall off the guiding rib 127, so that the cyclone separator 120 has a good dust accumulation preventing effect. Meanwhile, when dust attempts to enter the filter chamber 210 from the central axis direction of the filter chamber 210, since the first and second sides 4224c and 4224d have a distance between their projections on a plane perpendicular to the central axis of the filter chamber 210, it is likely that the dust is blocked by the guide rib 127 and cannot enter the filter chamber 210, thereby improving the blocking effect of the cyclone separator 120 on dust outside the filter chamber 210. It is to be understood that the arrangement of the guide ribs 127 is not limited thereto, and different arrangements may be selected as needed.

As shown in fig. 9, further, in an orthogonal projection of the guide ribs 127 on a plane perpendicular to the central axis of the filter cavity 210, an orthogonal projection of the first side 4224c of any one guide rib 127 is located between orthogonal projections of the first side 4224c and the second side 4224d in adjacent guide ribs 127 close to the first side 4224c. An orthographic projection of the second side 4224d of any one of the guide ribs 127 is positioned between orthographic projections of the first side 4224c and the second side 4224d in the adjacent blocking leaves 4224 close to the second side 4224d. That is, orthographic projections of adjacent guide ribs 127 on a plane perpendicular to the central axis of the filter chamber 210 coincide with each other.

In this way, the projection of the flow guiding structure 211 on the plane of the central axis of the filter cavity 210 has no gap, so that the air flow can easily pass through the air flow channel 212 in the process that the air with dust enters the filter cavity 210 through the flow guiding structure 211, and when the dust tries to enter the filter cavity 210 from the direction parallel to the central axis of the filter cavity 210, the dust is inevitably blocked by the guiding ribs 127 on the traveling route, and in addition, the dust is subjected to the action of gravity in the direction opposite to the direction of entering the filter cavity 210, so that the dust is difficult to enter the filter cavity 210, thereby further improving the primary filtering effect, and simultaneously, the falling of the dust in the filter cavity 210 is not influenced.

As shown in fig. 9, in the present embodiment, a blocking surface 4224e is formed between the first side edge 4224c and the second side edge 4224d, and an orthographic projection of the blocking surface 4224e on the main body 122 is an inclined straight line. That is, blocking surface 4224e is a plane that is inclined with respect to a plane perpendicular to the central axis of filter cavity 210, and blocking surface 4224e makes an angle of 10 ° to 45 ° with respect to the plane perpendicular to the central axis of filter cavity 210. In this way, the blocking surface 4224e can guide dust to slide off and prevent dust in the outside air flow from entering the filter cavity 210.

In another embodiment, as shown in fig. 9, an orthographic projection of a blocking surface 4224e formed between the first side edge 4224c and the second side edge 4224d on the body portion 122 is an arc. That is, the blocking surface 4224e is a curved surface extending from the first side 4224 to the second side 4224d, so that dust in the filter cavity 210 is prevented from falling off and the dust entering the filter cavity 210 is prevented from entering the filter cavity.

In another embodiment, as shown in fig. 9, an orthographic projection of a blocking surface 4224e formed between the first side edge 4224c and the second side edge 4224d on the body portion 122 is a wavy line. That is, blocking surface 4224e presents an undulating wavy surface, thereby further increasing the difficulty of dust entering filter chamber 210 without affecting the dust fall in filter chamber 210.

It is understood that the shape of the blocking surface 4224e is not limited to the above-mentioned embodiments, and may be configured into different shapes according to actual needs to meet different requirements.

In the cyclone separator 120, the guide ribs 127 are arranged on the flow guide structure 211, and the bent airflow channel 212 is formed between the adjacent guide ribs 127, so when the dust collector provided with the cyclone separator 120 stops working, dust in the filter cavity 210 can leave the filter cavity 210 through the airflow channel 212 under the action of gravity, thereby preventing excessive dust from being accumulated on the dust cup assembly 40 matched with the cyclone separator 120, and prolonging the service life of the dust collector. In the working process of the vacuum cleaner provided with the cyclone separator 120, the airflow can be preliminarily filtered while being allowed to enter the filter cavity 210 for further filtering, dust cannot enter the filter cavity 210 under the blocking action of the guide ribs 127, and the cyclone separator 120 can prevent the dust outside the filter cavity 210 from flowing back into the filter cavity 210.

In the dirt cup assembly 40, since the filter 110 is inserted into the cyclone 120, the cyclone 120 can block dust while allowing dust falling from the filter 110 to leave the filter chamber 210, thereby preventing dust from staying in the filter chamber 210 and returning to the filter 110 when the dirt cup assembly 40 is tilted. As such, the dirt cup assembly 40 is less prone to dirt accumulation and has a longer operating life.

As shown in fig. 7, fig. 7 is a schematic view of a cleaner 200 of a second embodiment, which cleaner 200 differs from the cleaner 100 of the first embodiment in the location of the motor assembly 140 between the airflow inlet 101 and the dirt cup assembly. However, the structure of the dirt cup assembly in the cleaner of the second embodiment is identical to that of the dirt cup assembly in the first embodiment, and the description thereof is omitted here. An air inlet channel 203 is arranged below the motor component 140, and air flow enters the dust cup component through the air inlet channel 203 after entering from the air flow inlet 101, enters the motor component 140 after being filtered by the dust cup component, and is finally discharged from the air outlet of the dust collector. It should be noted that fig. 7 is only a schematic diagram for illustrating the position of the motor assembly 140, and therefore, a simplified drawing method is adopted for other structures (such as a dust cup assembly), the contour lines of partial structures are incomplete, and the edge positions of partial structures are overlapped. Figure 7 also shows the direction of airflow within the cleaner.

As shown in fig. 8, when cleaning with a vacuum cleaner indoors, users often need both a handheld vacuum cleaner that cleans a small area and a special location and a canister vacuum cleaner that cleans a large area. In response to this need, the inventors have provided a dual mode vacuum cleaner based on any of the above embodiments. The dust collector is a double-working-mode dust collector, and the double-working mode comprises a handheld type dust collector which works independently and a horizontal type dust collector which is matched and connected with the expanded dust box. When the cleaner is removed from the expansion dust bin 160, the cleaner is in a handheld mode of operation; when the cleaner is mated with the expansion dust box 160, the cleaner is in a horizontal mode of operation. In the embodiment shown in fig. 8, rollers are mounted on the bottom of the expansion dust box 160 to facilitate movement of the cleaner.

When the dust collector is in a horizontal working mode, the environment with much dust and accumulated water needs to be cleaned. Therefore, the expansion dust box 160 is required to increase the dust space and to contain the sucked dirty water. The airflow sucked by the cleaner enters the main body 122 from the airflow inlet 101, and forms a cyclone downwardly around the filter 110 under the guidance of the main body 122. In this process, larger dust particles (and other larger foreign matters, liquid, etc.) fall toward the bottom of the dust collecting chamber 130 due to their larger gravity, and fall into the expanded dust box 160 through the dust pouring port following a part of the airflow; a portion of the air flow, after passing through the filter 124, passes through the hypa body 114 into the interior of the filter 110 due to the negative pressure. As a result, most of the dust and dirty water will fall into the dust bin 160, and the remaining smaller dust particles (and other smaller foreign objects, droplets) will be blocked by the hypa body 114. Since the large dust particles and most of the water are separated into the dust collecting chamber 130 by the cyclone 120, the burden of the HEPA body 114 is small, and it can be used for a longer time to generate clogging.

In one embodiment, the battery unit 150 contacts the expansion dust bin 160 when the cleaner is in the horizontal position. That is, the extension dust box 160 may have a support for the battery unit 150. The position of the battery unit 150 is set such that the structure of the cleaner is more stable.

As shown in fig. 10 to 17, a vacuum cleaner 300 of a third embodiment is provided, which is substantially the same in structure as the vacuum cleaner 200 of the second embodiment except for the shape of the filter, and the positional relationship between the filter and the cyclone separator and the position of the motor assembly are the same as those of the vacuum cleaner of the second embodiment, and will be described in detail with reference to the accompanying drawings.

As shown in fig. 10, 11 and 13, a dirt cup assembly 40 of the present preferred embodiment includes a cup body 41, a dust pouring lid 42, a first sealing ring 43 and a second sealing ring 44. The dirt cup assembly 40 is adapted to be mounted within a vacuum cleaner 300, such as a vacuum cleaner, to filter and collect dirt, solid waste, and liquids.

Wherein, one end of the cup body 41 is provided with a dust pouring opening for pouring dust. The dust pouring cover 42 cooperates with the dust pouring port to open or close the dust pouring port. When the dust pouring cover 42 closes the dust pouring opening, the dust pouring cover 42 and the cup body 41 form a dust collecting chamber 412 together. As shown in fig. 13 and 15, the first seal ring 43 is folded inward, and when the dust collection chamber 412 receives liquid, the first seal ring 43 deforms in a direction to improve the sealing performance of the dust collection chamber 412. The second sealing ring 44 is closer to the dust pouring cover 42 than the first sealing ring 43, and when negative pressure air current exists in the dust collection chamber 412, the second sealing ring 44 is deformed toward a direction of improving the sealing performance of the dust collection chamber 412.

In the dust cup assembly 40, when the dust pouring cover 42 closes the dust pouring port and liquid exists in the dust collection chamber 412, the first sealing ring 43 deforms in a direction of improving the sealing performance of the dust collection chamber 412 so as to prevent the liquid from leaking from the dust collection chamber 412; when negative pressure air flow exists in dust collection chamber 412, second sealing ring 44 deforms in a direction to improve the sealing performance of dust collection chamber 412 to prevent external air with higher pressure from entering dust collection chamber 412. In this way, the first sealing ring 43 and the second sealing ring 44 cooperate with each other in a time division manner, so that the dust cup assembly 40 in different dry and wet states has good sealing performance, and liquid or gas leakage is effectively prevented.

As shown in fig. 14 and 15, in the present preferred embodiment, the first sealing ring 43 circumferentially surrounds the ash pouring port to be fixed to the ash pouring port. The first sealing ring 43 includes a first fixing portion 432 and a first abutting portion 434, the first fixing portion 432 is connected to the cup 41, and the first abutting portion 434 is bent and extended from the first fixing portion 432 toward a central axis of the dust collecting chamber 412. When the dust pouring cover 42 closes the dust pouring opening of the cup body 41, the first abutting portion 434 of the first sealing ring 43 deforms to press the surface of the dust pouring cover 42 facing the dust collecting chamber 412 (i.e. generates deformation toward the direction of improving the sealing performance of the dust collecting chamber 412), thereby forming an inner sealing wall in the dust collecting chamber 412.

It is understood that in other embodiments, the first sealing ring 43 circumferentially surrounds the ash pouring cap 42 to be fixed to the ash pouring cap 42.

As shown in fig. 12, 13 and 15, the dust pouring lid 42 includes an upper end surface and a lower end surface which are oppositely arranged, and when the dust pouring lid 42 closes the dust pouring opening, the upper end surface of the dust pouring lid 42 forms a bottom wall of the dust collecting chamber 412, is in close contact with the first abutting portion 434 of the first sealing ring 43, and applies a pressure to the first abutting portion 434 in a direction toward the dust collecting chamber 412. Moreover, the distance between the inner side of the orthographic projection edge of the first sealing ring 43 on the dust dumping cover 42 and the edge of the central axis of the dust collecting chamber 412 is smaller than the distance between the inner side of the orthographic projection edge of the cup body 41 on the dust dumping cover 42 and the central axis of the dust collecting chamber 412. Thus, the liquid in the dust collecting chamber 412 can apply pressure to the surface of the first abutting portion 434 away from the dust pouring cover 42, so that the first abutting portion 434 is tightly contacted with the upper end surface of the dust pouring cover 42 to prevent the liquid from leaking. Moreover, the greater the depth of the liquid amount is, the greater the pressure applied by the first abutting portion 434 to the dust pouring lid 42 is, thereby achieving a better leakage prevention effect.

Further, a fixed edge 414 protrudes from the inner side wall of the cup body 41 in the dust collecting chamber 412 along the circumferential direction, and the fixed edge 414 bends towards the dust pouring opening direction to form a first clamping groove extending along the circumferential direction of the inner side wall of the cup body 41 together with the inner side wall of the cup body 41. When the dust pouring cover 42 seals the dust pouring opening, the first retaining groove is located in the dust collecting chamber 412 and the opening of the first retaining groove faces the dust pouring cover 42. The first fixing portion 432 is accommodated in the first retaining groove in a compressed state so as to fix the first sealing ring 43 on the cup body 41, and the first abutting portion 434 extends out of the first retaining groove and extends obliquely toward the dust pouring lid 42 so as to press the upper end surface of the dust pouring lid 42. In this way, the first seal 43 is firmly attached to the cup 41. It is to be understood that the fixing method of the first sealing ring 43 is not limited thereto, and may be provided as needed.

As shown in fig. 13, 14 and 15, since the negative pressure environment is formed due to the large flow velocity of the air flow in the dirt cup assembly 40 when only the inner sealing wall is provided and when no liquid or a small amount of liquid exists in the dirt cup assembly 40, the external air with a large pressure is likely to burst the first sealing ring 43 to open the inner sealing wall, in the present embodiment, the dirt cup assembly 40 further includes the second sealing ring 44 circumferentially surrounding the dust pouring cover 42, and when the dust pouring cover 42 closes the dust pouring opening, the second sealing ring 44 abuts between the dust pouring cover 42 and the cup body 41 to form an outer sealing wall located outside the dust collecting chamber 412.

As shown in fig. 13 and 15, the dust pouring lid 42 is provided with a second retaining groove located outside the dust collecting chamber 412, and the second retaining groove is circumferentially opened on the outer peripheral edge of the upper end surface and the lower end surface of the dust pouring lid 42 facing the cup body 41, so as to limit the second sealing ring 44 outside the dust collecting chamber 412 to form an outer sealing wall located outside the inner sealing wall together with the cup body 41 and the dust pouring lid 42.

Specifically, in the preferred embodiment, the second sealing ring 44 includes a second fixing portion 442 and a second abutting portion 444, the second fixing portion 442 is in a compressed state and is received in the second retaining groove, the second abutting portion 444 extends out of the second retaining groove to be in close contact with the inner sidewall of the cup body 41, and is deformed in a compressed state (i.e., deformed toward the direction of improving the sealing performance of the dust collecting chamber 412) under the combined action of the cup body 41 and the dust pouring cover 42, so as to further close the gap between the dust pouring cover 42 and the cup body 41 to form an outer sealing wall.

Further, the second abutting portion 444 of the second sealing ring 44 is bent and extended from the second fixing portion 442 in a direction away from the central axis of the dust collecting chamber 412 and gradually gets away from the dust collecting chamber 412. When the dust pouring cover 42 closes the dust pouring opening, a side surface of the second abutting portion 444 away from the second retaining groove is in close contact with an inner side wall of the cup body 41 forming the dust pouring opening to form an outer sealing cavity. Thus, when the external atmospheric pressure acts on the first sealing ring 43, the second abutting portion 444 is further compressed in the direction of the dust collecting chamber 412, so that the second abutting portion 444 is in closer contact with the inner side wall of the cup body 41, thereby further preventing gas leakage.

In another embodiment, as shown in fig. 16 and 17, the second sealing ring 44 has a substantially rectangular cross section and each cross section has substantially the same shape and size, the second abutting portion 444 can extend linearly from the first fixing portion 442 to a side away from the central axis of the dust collecting chamber 412, and when the dust pouring lid 42 closes the dust pouring opening, the second abutting portion 444 can be deformed to abut between the bottom wall of the cup 41 forming the dust pouring opening and the dust pouring lid 42 to form an outer sealing wall.

In the present embodiment, the first seal ring 43 and the second seal ring 44 are both made of an elastic material and have a certain elasticity, so that they can be compressed and deformed under pressure to be held in contact with each other.

Thus, the outer sealing wall and the inner sealing wall are sequentially arranged around the central axis along the circumference of the dust pouring cover 42, and when the outside air flow tries to enter the dust collecting chamber 412 from the space between the dust pouring cover 42 and the dust pouring port, the outside air flow first passes through the outer sealing wall (i.e. passes through the gap between the second sealing ring 44 and the cup body 41) and then passes through the inner sealing wall (i.e. passes through the gap between the first sealing ring 43 and the dust pouring cover 42), and finally enters the dust collecting chamber 412.

Therefore, when there is no liquid or a small amount of liquid in the dirt cup assembly 40, although there is a negative pressure airflow in the dirt cup assembly 40, the external air with a larger pressure is still blocked outside the dirt collection chamber 412 by the outer sealing wall, and cannot directly act on the inner sealing wall to push away the first sealing ring 43, thereby causing air leakage. Thus, the outer sealing wall and the inner sealing wall jointly form a double-sealing structure, so that the dust cup assembly 40 can play a good sealing role under the condition of liquid existence.

In fig. 15, in order to reflect that the first abutting portion 434 is in an interference fit with the dust pouring lid 42, the first abutting portion 434 partially intersects with the dust pouring lid 42 and the second seal ring 43. In fig. 15 and 16, the second seal 43 partially intersects the cup 41 to reflect the interference fit state of the second seal 43 with the cup 41. In practical applications, the first abutting portion 434 abuts against the ash pouring cover 42 in a compressed state without extending into the ash pouring cover 42 and the second sealing ring 43, and the second sealing ring 43 abuts against the cup 41 in a compressed state without extending into the cup 41.

As shown in fig. 10 and 11, the dust pouring lid 42 is rotatably coupled to the cup body 41 so that the dust pouring port can be easily opened or closed. As shown in fig. 13, 14 and 15, in particular, the dirt cup assembly 40 further includes a retaining member 45, the retaining member 45 is disposed on an outer side wall of the cup body 41, the dust pouring lid 42 is provided with a buckle 422 matching with the retaining member 45, and when the dust pouring lid 42 closes the dust pouring opening, the buckle 422 is retained on the retaining member 45 to fix the dust pouring lid 42 relative to the cup body 41. When the ash pouring opening needs to be opened, the buckle 422 can be separated from the clamping piece 45 so that the ash pouring cover 42 can be turned relative to the cup body 41 to open the ash pouring opening, and the inner side wall of the cup body 41 can be cleaned through the ash pouring opening.

Further, in the present embodiment, one end of the dust pouring lid 42 is hinged to the cup body 41 through a rotating shaft so as to be rotatable with respect to the cup body 41. The buckle 422 is arranged at the other end of the ash pouring cover 42, and the buckle 422 protrudes out of the outer side wall of the ash pouring cover 42 and bends and extends towards the direction away from the cup body 41. The middle part of the retaining member 45 is rotatably connected to the cup body 41 to form a lever structure, one end of the retaining member 45 away from the dust collecting chamber 412 is provided with a hook 452 bent towards the dust pouring cover 42, and one side surface of the hook 452 facing towards the dust collecting chamber 412 can be abutted against one side surface of the buckle 422 away from the dust pouring port to prevent the buckle 422 from moving towards the direction away from the dust collecting chamber 412, so that the dust pouring cover 42 is limited at the position for closing the dust pouring port.

Thus, when the ash pouring lid 42 needs to be opened, an operator can press the clamping member 45 to approach one end of the ash pouring opening (i.e. the end without the clamping hook 452), and the clamping hook 452 rotates towards the direction away from the ash pouring lid 42 by taking the joint with the cup body 41 as a rotation center to separate from the buckle 422, so that the buckle 422 loses the support of the clamping hook 452, and the ash pouring lid 42 rotates towards the direction away from the ash pouring opening relative to the cup body 41 to open the ash pouring opening. When closing the cover 42, the operator can push the cover 42 to rotate relative to the cup 41, so that the buckle 422 on the cover 42 slides relative to the hook 452, and simultaneously push the retaining member 45 to rotate and retain the hook 452. It is understood that the installation and opening and closing manner of the dust pouring cover 42 is not limited thereto, and may be set as required.

The dust cup assembly 40 is provided with the outer sealing cavity and the inner sealing cavity which have different functions, so that the dust cup assembly 40 can have good sealing effect under the condition of no accumulated water in the dust cup assembly 40, and liquid or gas leakage is avoided. Moreover, since the dust pouring lid 42 is only in contact with the first sealing ring 43 and not held by it, the dust pouring lid 42 can be easily opened, so that the dust pouring lid 42 can be easily opened and closed without affecting the sealing performance, thereby facilitating the cleaning of the inside of the dirt cup assembly 40.

As shown in fig. 10 and 11, a vacuum cleaner 300 of the present preferred embodiment includes the above-mentioned dirt cup assembly 40. In the present embodiment, the vacuum cleaner 300 is a hand-held wet and dry vacuum cleaner. An operator may hold the cleaner 300 to clean dust, solid debris, and liquids.

Specifically, in the preferred embodiment, the vacuum cleaner 300 includes a handle assembly 20 for gripping, a dirt cup assembly 40, a motor assembly 60 for providing power, and an airflow inlet 80, wherein the motor assembly 60 is located between the airflow inlet and the dirt cup assembly 40 for generating a suction negative pressure, the airflow inlet 80 is used for introducing a dust-laden airflow into the dirt cup assembly 40, and a filter is disposed in the dirt cup assembly 40. As such, the dusty gas stream enters the dirt cup assembly 40 from the gas stream inlet, is filtered by the filter within the dirt cup assembly 40, flows upward, and is discharged toward the motor assembly 60.

Above-mentioned dust catcher 300, because it installs that sealing performance is good and open and shut convenient dirt cup subassembly 40, consequently can prevent the condition that liquid, gas leakage from appearing, and can easily open inside dirt cup subassembly 40 in order to wash dirt cup subassembly 40, consequently increased this dust catcher 300's job stabilization nature, improved user experience.

When the dust collector of any embodiment works, the extension pipe and the dust collection head can be connected. The dust collector is directly or indirectly detachably connected with the extension pipe, one end of the extension pipe is communicated with an airflow inlet of the dust collector, the other end of the extension pipe is communicated with the dust collection head, and the dust collection head is provided with a suction channel communicated with the interior of the extension pipe, so that dust enters the extension pipe through the suction channel and then enters the airflow inlet along the extension pipe. The extension pipe can be a hard pipe, a hose, a combination of a soft pipe and a hard pipe, or an extension pipe, and when the extension pipe is used in specific work, a user can select the accessory according to actual application scenes. When the cleaner does not require an extension tube for cleaning, for example other accessories such as a crevice nozzle, a mite removal nozzle etc. are required, the extension tube can be removed from the airflow inlet of the hand-held cleaner and the required accessories fitted to the airflow inlet of the cleaner. One end of the extension pipe is detachably and directly connected with the airflow inlet of the dust collector, for example, the extension pipe can be installed on the airflow inlet and detached from the airflow inlet through a snap quick-release structure. Therefore, the disassembly and assembly are convenient.
