The extending end of the guide rail 331 is provided with a protruding portion 332, and a third spring 333 engaged with the protruding portion 332, the extending direction of the third spring 333 is perpendicular to the axis X, and when the third spring 333 is in a stretched state, the protruding portion 332 is driven by the third spring 333 to protrude outwards beyond the upper surface of the guide rail 331. When the user presses so that the third spring is compressed 333, the protrusion 332 moves in a direction approaching the axis X and is lower in height than the upper surface of the guide rail 331. The end of the connecting portion 33 is further provided with a second hook portion 334. The second hook 334 and the guide 331 are located on the same line.

The front inner wall of the connecting portion 33 is further provided with a wiper 335, and the wiper 335 is provided in a circular ring shape. The wiper 335 is a deformable resilient material, and preferably the wiper 335 may be a resilient rubber or a brush.

Preferably, a sealing ring is further arranged on the bottom cover 32, and the sealing ring is matched with the cup body 31 to form a sealing space.

Referring to fig. 3A-3B, a filter 40 of a vacuum cleaner according to an embodiment of the present invention is shown, and the entire filter 40 has a substantially conical shape. It comprises a body 41, a first separator 42 arranged at the front end of the body 41, an air inlet channel 43 positioned at the front end of the first separator 42, and a second separator 44 accommodated in the body 41. The first separator 42 is a coarse ash separator and the second separator 44 is a fine ash separator. The first separator 42 is a metal mesh enclosure with a plurality of meshes on the surface, and the second separator 44 is a HEPA. The surface of the first separator 42 is further provided with a rectangular opening 421. The filter device 40 further comprises an air guiding wall 45 inside the first separator 41. The upstream of the air inlet channel 43 is connected to the air inlet 323 on the bottom cover 32, the downstream of the air inlet channel 43 is connected to the upstream of the air guiding wall 45, and the downstream of the air guiding wall 45 is connected to the opening 421 on the first separator 42. When the cleaner 100 is in operation, a dust-laden air stream is drawn in from the air inlet 323 in the bottom cover 32, enters the air guide wall 45 along the air inlet channel 43, is thrown out from the opening 421 in the first separator 42 at a high speed by the rotational separation of the air guide wall 45, and continues to flow through the first separator 42, wherein larger particles of dust in the air stream cannot pass through the mesh openings in the surface of the first separator 42 and are retained in the cup 31. The air flow with the small particle dust separated by the first separator 42 passes through the mesh and then continues to be separated by the second separator 44 located downstream, and the air flow with the small particle dust removed is discharged through the rear end of the body 41.

The filter device 40 is further provided with a driving device 45, the driving device 45 being configured to provide a driving force for driving the dirt cup assembly 30 to move, such that the dirt cup assembly 30 moves forward in the axial direction. Specifically, the driving device 45 includes an annular elastic block 451 sleeved on the body 41, and a fourth spring 452 cooperating with the elastic block 451. The annular elastic piece 451 is movable back and forth in the axial direction on the body portion 41. One end of the fourth spring 452 abuts against the rear end boss 411 of the body 41, and the other end abuts against the elastic block 451. The front end of the body 41 is further provided with a protrusion 411, and the protrusion 411 is used to limit the elastic block 451 from moving forward excessively. As the elastic block 451 moves rearward in the axial direction, the fourth spring 452 is gradually compressed to accumulate elastic potential energy. The fourth spring 452 releases the accumulated elastic potential energy when in a stretched state and pushes the elastic block 451 forward rapidly, so that the elastic block 451 is located at the forefront end of the body portion 41 and abuts against the projection 412 at the front end of the body portion 41.

The driving device 45 adopts a spring driving mode, and has simple structure and low cost.

With continued reference to fig. 3B, the inner side wall of the extending end of the main body 41 is further provided with a plurality of fastening portions 413, and the fastening portions 413 are used to fix the filtering device 40 to the main body 10, and for details, reference will be made to the following description.

Referring to fig. 4A-4B, a main body 10 according to an embodiment of the present invention includes a tubular outer case 11 and a power unit 12 accommodated in the outer case 11. The power device 12 is a motor 121 and an impeller 122 driven by the motor 121, and the impeller 122 is driven by the motor 121 to rotate at a high speed to generate a negative pressure, so that a suction force is formed to suck dust-containing air from the air inlet 323 and finally discharge the dust-containing air from the air outlets on both sides of the outer shell 11. The housing 11 has a receiving cavity 111 formed therein at a front end of the power unit 12, and the receiving cavity 111 is configured to receive the connection portion 33 of the dirt cup assembly 30 and the body portion 41 of the filter device 40. The front end of the power unit 12 is provided with an engaging portion 123 that engages with a locking portion 412 on the main body 41, and is configured to fix the filter unit 40 to the main body 10 by means of a rotational locking, as shown in fig. 6.

The inner wall of the outer case 11 is provided with a guide groove 113 which is fitted to the guide rail 331 of the connecting portion 33. It is easily conceivable that a person skilled in the art may provide guide rails on the side walls of the outer housing 11 and guide grooves on the connection portion 33 according to actual needs. In addition, the number of the guide rail 331 and the guide rail 113 is one in the present embodiment, but one or two pairs of guide rail guides or more may be provided according to actual needs by those skilled in the art. The guide rail 331 of the connecting portion 33 is accommodated in the guide groove 113 and slides back and forth in the axial direction. Further, in order to prevent the connection portion 33 from sliding outwards excessively, the dust cup assembly 30 is broken when falling from the main body portion 10, the front end of the corresponding outer housing 11 is provided with a blocking portion 114, and the blocking portion 114 is matched with the protruding portion 332 on the connection portion 33. The interference fit between the blocking portion 114 and the protruding portion 332 is used to prevent the connecting portion 33 from sliding outwards, so as to prevent the dust cup assembly 30 from falling.

The outer shell 11 is provided with a locking part 115 matched with a second clamping hook part 334 on the connecting part 33, and the dust cup assembly 40 is fixedly mounted on the main body 10 through the clamping fit of the locking part 115 and the second clamping hook part 334.

The main body 10 is further provided with a trigger device for controlling the locking portion 115 to unlock at one end near the grip portion 20, and the trigger device includes a release button 116 provided on the outer housing 11 and a fifth spring 117 engaged with the release button 116. The release button 116 is disposed near the grip 20, so that the user can toggle the release button 116 by thumb when operating the cleaner with one hand, thereby facilitating the use of the user. The extending direction of the fifth spring 117 is parallel to the axis X. In the stretched state of the fifth spring 117, the release button 116 is driven by the fifth spring 117 to engage with the locking portion 115, and the locking portion 115 is always engaged with the second hook portion 334 under the engagement of the release button 116. When the user operates the release button 116, the fifth spring 117 is compressed, the release button 116 moves backward along the axial direction, and at the same time, the release button 116 drives the locking portion 115 to move, the locking portion 115 contacts the second hook portion 334 to be in snap fit, at this time, the elastic compression force provided by the fourth spring 452 of the driving device 45 drives the elastic block 451 to move forward and pop out rapidly along the axial direction, and at the same time, the elastic block 451 drives the connecting portion 33 to move forward axially along the guide rail 331 until the protruding portion 332 on the guide rail 331 is in interference fit with the blocking block 114 on the outer housing, so as to prevent the dust cup assembly 40 from moving forward continuously.

The grip portion 20 accommodates therein a power supply unit 21 and a control circuit board 22, and the control circuit board 22 is used for controlling the power supply unit 21 to supply power to the motor in the main body portion 10. The outer surface of the further grip portion 20 is further provided with a switch 23, and the switch 23 is electrically connected to the control circuit board 22, so that a user can switch on or off the power supply of the cleaner 100 by touching the switch 23.

The preferred power supply assembly 21 is a lithium battery. The end of the holding part 20 is also provided with a charging port through which the power supply assembly 21 is charged.

Referring to fig. 6-8, in the whole installation process of the dust collector 100 according to the embodiment of the invention, the filter 40 is fixed in the outer shell 11 of the main body 10 by rotating and fastening, then the dust cup assembly 30 is sleeved on the filter 40, the guide rail 331 on the connecting part 33 is aligned with the guide groove 113 in the outer shell 111 of the main body 10, the protruding part 332 is pressed downwards so that the guide rail 331 can be smoothly installed in the guide groove 113, the dust cup assembly 30 is continuously pushed backwards along the axial direction, at this time, the connecting part 33 drives the driving device 45 to move backwards together, the fourth spring 452 is gradually compressed, the second matching part 3132 of the connecting rod 313 on the cup 31 is abutted with the front end wall of the outer shell 11, and the second spring 315 is compressed to enable the lock catch 311 to be in a fastening fit with the first catch 322, the dust cup assembly 30 continues to move backwards until the second catch 332 on the connecting part 33 is snapped with the locking part 114 on the main body 10, at this time, the whole dust collector 100 is assembled.

Referring to the schematic views of the cleaner shown in fig. 9 and 10 in the in-use and dust-pouring states, the entire dirt cup assembly 30 is movable in the axial direction relative to the main body 10 between a first position and a second position. In the first position, the rear end wall of the cup 31 abuts against the front end wall of the outer case 11, and at the same time, the connecting portion 33 is completely accommodated in the accommodating chamber 111, and the second hook portion 334 is snap-fitted with the locking portion 115. In the second position, the rear end wall of the cup 31 is separated from the front end wall of the outer case 11, the second catching portion 334 is released from the snap fit with the locking portion 115, and the protruding portion 332 is interference fit with the blocking piece 114 while the connecting portion 33 is mostly exposed to the outside of the housing cavity 111.

The wiper 335 is capable of sliding relative to the surface of the first separator 42 as the dirt cup assembly 30 moves in an axial direction, i.e., from the first position to the second position. Some of the dirt within the mesh of the first separator 42 or hair entangled with the first separator surface 42 is removed by the relative movement of the wiper 31 and the first separator surface 42.

The inner diameter of the wiper 335 is preferably smaller than or equal to the outer diameter of the first separator 42, so that the wiper 335 rubs against the surface of the first separator 42, and the dust scraping effect is better.

The preferred distance traveled by the connecting portion 33 from the first position to the second position is greater than the axial length of the mesh coverage of the first separator 42, and the wiper 335 is positioned at the end of the first separator 42 when the connecting portion 33 is in the first position, such that the wiper 335 cleans the entire surface mesh of the first separator 42 when the connecting portion 33 is moved from the first position to the second position. Incomplete cleaning of the surface of the first separator 42 with mesh dust or hair accumulation at the front end of the first separator can be avoided. Avoid the unclean user to need to carry out secondary clearance.

As will be described below with reference to fig. 9 and 10, when the user needs to clean the dust in the cup 31 after completing the dust collection operation, the release button 116 is only pushed backward, so that the release button 116 drives the locking portion 115 to move, so that the locking portion 115 is disengaged from the second hook 334 of the connecting portion 33, at this time, the driving device 45 drives the connecting portion to move, that is, the fourth spring 452 in a compressed state releases elastic potential energy to make the elastic block 451 pop out rapidly along the axial direction, and at the same time, the popped elastic block 451 drives the connecting portion 33 to move rapidly forward along the axial direction until the protrusion 334 on the end of the connecting portion 33 interferes with the blocking block 114 on the outer housing 11, and the whole process dust cup assembly 30 completes moving from the first position to the second position, and at the same time, the wiper 335 performs relative sliding friction with the surface of the first separator 42, so as to scrape the dust on the surface of the first separator 42 or in the mesh. When the dust cup assembly 30 moves from the first position toward the second position, since the rear end wall of the cup body 31 is separated from the front end wall of the outer case 11, the second spring 315 in a compressed state drives the second fitting portion 3132 of the link 313 to move backward and drives the first fitting portion 3131 of the link 313 to move backward at the same time, the inclined surface 3133 of the first fitting portion 311 presses the latch 311 and compresses the first spring 312, so that the latch 311 is released from the snap fit with the first catch portion 322 of the bottom cover 32, the bottom cover 32 is sprung open by the torsion spring, and dust in the cup body 31 is poured out from the opening of the bottom cover 32. The user can finish one-touch operation through one hand in the whole operation process, and the user does not need to touch the bottom cover and the dust cup component in the whole operation process, so that the possibility that the hands of the user are polluted is avoided, and the operation experience of the user is improved.

After the ash pouring operation is completed, the user operates the dust cup assembly 30 to move backwards along the axial direction, at this time, the fourth spring 452 in the driving device 45 is gradually compressed until the rear end wall of the cup body 31 abuts against the front end wall of the outer shell 11, the second matching portion 3132 of the connecting rod 313 is pressed by the front end wall of the outer shell 11 to move forwards, meanwhile, the second spring 315 is compressed to drive the first matching portion 3131 to move forwards, the inclined surface 3133 of the first matching portion 3131 is disengaged from the lock catch 311, the first spring 312 is changed from a compressed state to a stretched state, and the lock catch 311 and the first clamping hook portion 322 of the bottom cover 32 are mutually buckled again. At the same time, the second hook 334 of the connecting part 33 cooperates with the locking part 115 to generate a click sound to alert the user that the dirt cup assembly 30 has moved to the first position and to complete the fixing with the main body 10. At this time, the whole operation process is completed, and the user can continue to perform dust collection work or store the dust collector.

Of course, if the user cannot completely discharge the dust in the cup 31 after operating the release button 116 once, the above-mentioned dust pouring operation may be repeated several times until the dust in the cup 31 is completely discharged.
