The air outlet is provided with an air outlet, air flow can flow into the machine body assembly 40 from the dust collection opening 101, then is discharged out of the machine body assembly 40 from the air outlet on the air outlet, and the air outlet is internally provided with an air outlet filter.

The suction assembly 401 is configured to form a suction airflow in operation, the suction airflow can suck the dust near the dust suction opening 101 into the dust bin 10, the airflow with the solid dust entering through the dust suction opening 101 is subjected to gas-solid separation by the separator 402, for example, the separator 402 can be a cyclone separator, dust enters the cyclone separator along with the airflow from the dust suction opening 101 at a high speed and tangentially, and the high-speed rotating airflow can effectively centrifugally separate most of dust particles, so that most of the solid dust in the airflow is trapped in the dust bin 10. Then, the air flows from the dust bucket 10 to the suction assembly 401 through the air flow channel between the separator 402 and the suction assembly 401, and then flows into the air outlet part and flows out through the air outlet.

When dust in the dust bucket 10 is accumulated much, cleaning of the dust bucket 10 is required. For example, referring to fig. 3 to 7 in conjunction with fig. 1 and 2, in fig. 3, the dust bucket 10 is located at the first position, and at this time, the bottom cover 30 is engaged with the latch assembly 20 and covers the dust outlet 11. The user can normally perform a cleaning operation, such as a dust suction operation, using the cleaning apparatus, and the sucked dust falls into the dust bucket 10.

When cleaning the dust barrel 10 is required, referring to fig. 1 and fig. 5, a user can drive the dust barrel 10 to move from the first position to the second position relative to the machine body assembly 40 through the unlocking assembly 50, and when the dust barrel 10 moves relative to the machine body assembly 40, the unlocking trigger 42 can trigger the lock catch assembly 20 to unlock, and the bottom cover 30 is unlocked and can rotate relative to the dust barrel 10 around the hinged connection, the dust outlet 11 can be opened by the bottom cover 30, and the opened state of the bottom cover 30 can be referred to fig. 6 and fig. 7. After the bottom cover 30 is opened, the dust in the dust bucket 10 can be poured out of the dust bucket 10 to complete cleaning of the dust bucket 10.

In the case of gas-solid separation, the surface of the separator 402 may be stained with dust, hair, etc. which is not easy to clean, and in order to clean the separator 402, further, in the embodiment of the present invention, referring to fig. 5 and 7, the scraping strip 12 is disposed on the inner wall of the mounting opening in a ring, and one end of the scraping strip 12 abuts against the outer wall of the separator 402. When the dust bucket 10 moves relative to the machine body assembly 40, the scraping strip 12 also moves relative to the separator 402, and during the movement, substances such as dust on the outer wall of the separator 402 can be scraped from the outer wall of the separator 402 so as to be poured out from the dust outlet 11. When the unlocking assembly 50 drives the dust barrel 10 to move relative to the machine body assembly 40, the unlocking operation of the bottom cover 30 and the dust scraping operation of the separator 402 are completed simultaneously, and a user can realize a plurality of functions through one-key operation, so that the user is prevented from contacting the interior of the dirty dust barrel 10, and the dust barrel is more convenient for the user to use.

Further, referring to fig. 8 and 9 in conjunction with fig. 2 and 3, in the embodiment of the present invention, a clamping buckle 31 is disposed at one end of the bottom cover 30 corresponding to the latch assembly 20. One implementation manner of the latch assembly 20 is that the latch assembly 20 includes a swing link cover 21, two swing links 22 symmetrically disposed, and a first elastic structure 23.

The two swing rods 22 are rotatably connected in the switching space, and two ends of the swing rods 22 extend out of the switching space respectively. The first elastic structures 23 are respectively connected with the two swing rods 22. The implementation manner of the first elastic structure 23 includes various types, and the first elastic structure 23 includes, but is not limited to, a compression spring, a torsion spring and a shrapnel, and two acting ends of the first elastic structure 23 are respectively connected with two swing rods 22.

Referring to fig. 3, when the dust bucket 10 is located at the first position, the two swing rods 22 clamp the clamping buckle 31 under the action of the first elastic structure 23.

Referring to fig. 4, when the dust bucket 10 moves into the second position, the unlocking trigger 42 drives the swing link 22 to rotate to release the snap fastener 31. When the dust bucket 10 moves relative to the machine body assembly 40, such as along the direction in fig. 4, the dust bucket 10 moves downward, and the unlocking trigger 42 can drive the two swing rods 22 to rotate, so as to release the clamping buckle 31. The clamping buckle 31 loses clamping force, and the bottom cover 30 rotates around the hinge part relative to the dust barrel 10 under the action of gravity, so that the dust outlet 11 is opened. The bottom cover 30 is opened as shown in fig. 6 and 7.

With continued reference to fig. 2 and fig. 3, referring to fig. 8 and fig. 9, in one implementation manner of the swing rod, the swing rod 22 includes a switching portion 221, and a first swing arm 222 and a second swing arm 223 disposed at two ends of the switching portion 221, where the swing rod 22 is rotatably connected in the switching space through the switching portion 221, and the first swing arm 222 and the second swing arm 223 at least partially extend out of the switching space respectively.

Further, when the housing groove 41 is provided on the body assembly 40, the unlocking trigger piece 42 is disposed on two opposite groove walls of the housing groove 41, the two unlocking protrusions can narrow the space between the groove walls on both sides, when the two first swing arms 222 move and contact with the unlocking protrusions, the two first swing arms 222 are pressed by the unlocking protrusions, and the two second swing arms 223 are far away from each other, so as to release the bottom cover 30. The unlocking protrusion may be disposed at the opening 43 of the corresponding dust outlet 11 of the receiving groove 41.

Further, in order to prevent the first swing arm 222 from being damaged when it contacts with the unlocking protrusion, a guiding surface is provided along the axial direction of the dust bucket 10 at least toward one side in the accommodating groove 41. The guide surface may be an inclined surface or an arc surface, and when the first swing arm 222 contacts with the unlocking protrusion, the first swing arm 222 may move along the guide surface, so as to perform smooth or sleek movement, thereby reducing hard contact between the first swing arm 222 and the unlocking protrusion, and avoiding damage to the first swing arm 222. Further, the end of the first swing arm 222 far from the second swing arm 223 may be arc-shaped or spherical, so as to further prevent damage. If the latch assembly 20 is to be moved out of the accommodating groove 41, the unlocking protrusion may have a guiding surface on the side facing the outside of the accommodating groove 41 in addition to the guiding surface on the side facing the inside of the accommodating groove 41, so as to guide the first swing arm 222 into the accommodating groove 41. Of course, the opposite side of the two unlocking protrusions may also be provided with a guiding surface.

Further, in embodiments of the present invention, the unlocking assembly 50 may be implemented in a variety of ways, for example, referring to fig. 2, and in one implementation, the unlocking assembly 50 includes at least one pair of driving gears 51 and a pull rod 52. The dust barrel 10 is driven to move relative to the machine body assembly 40 through the transmission gear 51. Alternatively, referring to FIG. 15, the unlocking assembly 50 includes an unlocking pushrod 55 by which the dust bucket 10 is movable relative to the housing assembly 40.

The following describes the implementation of the two unlocking assemblies 50.

Referring to fig. 10 and 11 in combination with fig. 2 and 3, the unlocking assembly 50 includes at least one pair of driving gears 51 and a pull rod 52. At least one pair of drive gears 51 are rotatably coupled to the body assembly 40. The two sides of the pull rod 52 corresponding to the transmission gears 51 are respectively provided with a pull rod rack 521, the pull rod 52 extends into the space between the two transmission gears 51 in the pair, and the pull rod rack 521 is meshed with the two transmission gears 51 in the pair.

Referring to fig. 9 and 12 in combination with fig. 2 and 3, two opposite sliding rails 13 are provided on the outer side wall of the dust barrel 10, a dust barrel rack 14 is provided on the opposite side of the two sliding rails 13, and the sliding rails 13 are respectively engaged with the paired transmission gears 51 through the dust barrel rack 14.

Referring to fig. 3 to 7, when the pull rod 52 moves along the second position toward the first position, the transmission gear 51 is driven to rotate, and the transmission gear 51 drives the dust bucket 10 to move from the first position toward the second position through the dust bucket rack 14.

The dust barrel rack 14 on the dust barrel 10 is linked with the rack on the pull rod 52 through the transmission gear 51, and when the pull rod 52 moves up and down, the dust barrel 10 can be driven to move in the opposite direction through the transmission gear 51. When the pull rod 52 moves upwards, the dust barrel 10 is driven to move downwards relatively, and when the pull rod 52 moves downwards, the dust barrel 10 is driven to move upwards relatively. By the gear and rack transmission principle, stable and high-precision transmission can be realized, so that the pull rod 52 and the dust barrel 10 can move more stably.

For example, referring to fig. 3, when the dust bucket 10 is in the first position, the bottom cover 30 is engaged with the latch assembly 20 and covers the dust outlet 11.

When the dust bucket 10 needs to be cleaned, referring to fig. 4 and 5, taking the direction of the drawing as an example, the user can pull the pull rod 52 upwards, and when the pull rod 52 moves upwards, the pull rod rack 521 drives the two transmission gears 51 to rotate respectively, for example, the left transmission gear 51 rotates anticlockwise, and the right transmission gear 51 rotates clockwise. When the transmission gear 51 rotates, the dust barrel rack 14 drives the dust barrel 10 to move downwards, that is, the dust barrel 10 moves from the first position to the second position relative to the machine body assembly 40, the unlocking trigger 42 can trigger the lock catch assembly 20 to unlock, and the unlocking process can refer to the content in the above embodiment, which is not described herein. After the latch assembly 20 is unlocked, the bottom cover 30 loses clamping force and can rotate around the hinged connection point relative to the dust bucket 10, the bottom cover 30 can open the dust outlet 11, and the bottom cover 30 can be opened as shown in fig. 6 and 7. After the bottom cover 30 is opened, the dust in the dust bucket 10 can be poured out of the dust bucket 10 to complete cleaning of the dust bucket 10.

When the dust bucket 10 is cleaned, the unlocking assembly 50 is configured to allow movement of the dust bucket 10 relative to the body assembly 40 from the second position to the first position. The user can push the pull rod 52 downwards, and when the pull rod 52 moves downwards, the pull rod rack 521 drives the two transmission gears 51 to rotate respectively, for example, the transmission gear 51 on the left rotates clockwise, and the transmission gear 51 on the right rotates anticlockwise. When the transmission gear 51 rotates, the dust barrel rack 14 drives the dust barrel 10 to move upwards, namely, the dust barrel 10 moves to the first position relative to the machine body assembly 40, and the separator 402 can extend into the dust barrel 10 from the mounting hole. When the dust bucket 10 returns to the first position, the bottom cover 30 can be rotated and the bottom cover 30 can clamp the clamping buckle 31 on the bottom cover 30 through the locking assembly 20, so that the bottom cover 30 covers the dust outlet 11. Another way to move the dust barrel 10 back to the first position is that the user can push the dust barrel 10 back to the first position while covering the dust outlet 11 through the bottom cover 30, and the pull rod 52 correspondingly moves back when pushing the dust barrel 10.

In order to further ensure smooth movement between the dust bucket 10 and the machine body assembly 40, in the embodiment of the present invention, referring to fig. 2 and 12, the machine body assembly 40 is provided with a guide bar 44, and the guide bar 44 extends along the moving direction of the dust bucket 10. The surface of the slide rail 13, which is away from the dust barrel rack 14, is provided with a guide groove 15 corresponding to the guide bar 44, and the guide bar 44 is slidably connected in the guide groove 15. The relative position between the dust barrel 10 and the machine body assembly 40 can be limited through the guide strip 44 and the guide groove 15, meanwhile, the dust barrel 10 and the machine body assembly 40 can only move along the extending direction of the guide strip 44, dislocation between the dust barrel 10 and the machine body assembly 40 in the relative movement process is avoided, and meanwhile, the relative movement process can be more stable.

Further, the side of the sliding rail 13 facing away from the dust barrel rack 14 is also provided with a avoiding groove 16. The contact area between the sliding rail 13 and the groove wall of the accommodating groove 41 can be reduced through avoiding the groove 16, so that the friction force between the sliding rail 13 and the groove wall of the accommodating groove 41 is reduced, and the relative movement between the dust bucket 10 and the machine body assembly 40 is smoother.

When the dust bin 10 is located at the first position, in order to lock the relative position between the dust bin 10 and the machine body assembly 40, referring to fig. 2, 11 and 13, the unlocking assembly 50 further includes at least one pair of positioning members 53 and a second elastic structure 54, the positioning members 53 include a rotation hole 531, and clamping teeth 532 and hook portions 533 disposed at two ends of the rotation hole 531, the positioning members 53 are rotatably connected to the machine body assembly 40 through the rotation hole 531, and the second elastic structure 54 is located between the two hook portions 533 and connected to the two hook portions 533 respectively. Referring to fig. 10, positioning grooves 522 are respectively formed on two sides of the pull rod 52 corresponding to the positioning pieces 53, and the pull rod 52 is located between the two positioning pieces 53 in the pair. The implementation manner of the second elastic structure 54 includes various types, and the second elastic structure 54 includes, but is not limited to, a compression spring, a torsion spring, and a spring sheet, and two acting ends of the second elastic structure 54 are respectively connected to two hook portions 533.

Referring to fig. 13 in conjunction with fig. 3 and 10, when the dust bucket 10 is located at the first position, the dust bucket 10 is not moved upwards due to the restriction of the suction assembly 401, and meanwhile, under the action of the second elastic structure 54, the positioning member 53 is clamped in the positioning slot 522 by the clamping teeth 532, and the clamping hook 533 is clamped with the bottom of the sliding rail 13. Under the action of the second elastic structure 54, the two hook portions 533 are far away from each other and extend into the bottom of the sliding rail 13. When the two hook portions 533 are separated from each other, the two engaging teeth 532 are close to each other according to the lever principle and are engaged into the positioning slot 522. In the absence of other forces exerted on the pull rod 52 or the dust bucket 10, the positioning member 53 prevents the dust bucket 10 from moving downward relative to the machine body assembly 40, and the suction assembly 401, in combination, ensures a stable relative position between the dust bucket 10 and the machine body assembly 40.

Referring to fig. 14 in conjunction with fig. 4, when the pull rod 52 moves in the second position toward the first position, the engaging teeth 532 are disengaged from the positioning groove 522, and the hook 533 is disengaged from the bottom of the slide rail 13. Taking the orientation of fig. 14 as an example, when the pull rod 52 moves upward, the engaging teeth 532 are pressed by the pull rod 52 to be away from each other, the two hook portions 533 are close to each other, the two hook portions 533 are separated from the bottom of the slide rail 13, and the dust bucket 10 can move relative to the machine body assembly 40 without limitation of the positioning member 53.

When the unlocking component 50 comprises the positioning piece 53, the cleaning process of the dust barrel 10 is that firstly, the pull rod 52 drives the clamping teeth 532 on the positioning piece 53 to be separated from the positioning groove 522, and the clamping hook 533 is separated from the bottom of the sliding rail 13, so that the position limitation between the dust barrel 10 and the machine body component 40 is released. Then, the pull rod 52 drives the transmission gear 51 to rotate, so that the dust barrel 10 is driven to move from the first position to the second position, the lock catch assembly 20 is triggered to unlock, the bottom cover 30 is opened, and dust can be poured out from the dust outlet 11.

In the embodiment of the invention, the positioning piece 53 and the transmission gear 51 are arranged at intervals along the length direction of the pull rod 52, so that interference between the positioning piece and the transmission gear is avoided. Alternatively, the positioning members 53 and the transmission gears 51 may be arranged in a stacked manner along the thickness direction of the tie rod 52, and each positioning member 53 corresponds to one transmission gear 51 and shares one rotation shaft 534 with the corresponding transmission gear 51 when arranged in a stacked manner. The positioning member 53 and the transmission gear 51 have relatively independent rotation spaces, which do not interfere with each other, and the number of rotation shafts 534 can be reduced. Further, in the embodiment of the present invention, referring to fig. 11, the thickness of the hook portion 533 is greater than the thickness of the clamping tooth 532, so as to form a transfer slot, and the transmission gear 51 may be located in the transfer slot.

In order to reduce the abrasion between the positioning piece 53 and the transmission gear 51, a gasket is arranged between the positioning piece 53 and the transmission gear 51, so that the friction between the positioning piece 53 and the transmission gear 51 can be prevented by arranging the gasket, the abrasion probability of the positioning piece 53 and the transmission gear 51 is reduced, and the service life is prolonged.

With continued reference to fig. 10, one possible implementation of the pull rod 52 is that the pull rod 52 includes a body section 523 and an active section 524 connected in sequence. The action section 524 faces the face of the transmission gear 51 and is divided into a transmission area and an unlocking area along the thickness direction, and the transmission area is provided with a pull rod rack 521. The unlocking zone is of a planar structure, and after the clamping teeth 532 are separated from the positioning grooves 522, the clamping teeth slide along the unlocking zone. For convenience of operation, an operation handle is disposed at an end of the main body section 523 away from the acting section 524, such that the operation handle and the main body section 523 form a T-shaped structure, and the user pulls and pushes the pull rod 52 through the operation handle. When the user pulls the pull rod 52 upwards, the clamping teeth 532 are separated from the positioning groove 522 and are abutted against the unlocking region, and the clamping teeth 532 are extruded by the unlocking region to be away from each other, so that the two clamping hook portions 533 are driven to be close to each other. When the pull rod 52 continues to move upwards, the pull rod rack 521 drives the two transmission gears 51 to rotate respectively, so as to drive the dust bucket 10 to move downwards, and thus the unlocking trigger 42 can trigger the lock catch assembly 20 to unlock.

Further, the housing groove is formed in the housing assembly 40 corresponding to the operating handle, and when the dust bucket 10 is located at the first position, the operating handle is housed in the housing groove, so that the end face of the operating handle does not exceed the surface of the housing assembly 40, and the space occupied by the housing assembly 40 is prevented from being increased.

Further, when the unlocking assembly 50 includes the positioning member 53, the positioning member 53 needs to be unlocked first, and then the pull rod 52 drives the transmission gear 51 to rotate, so as to better achieve the above effect, and in the embodiment of the present invention, a buffer slot 525 is further provided between the main body section 523 and the action section 524, as shown in fig. 10, on the transmission area. When the dust bucket 10 is in the first position, the transmission gear 51 is positioned in the buffer tank 525. The buffer groove 525 is spaced from the pull rod rack 521 by a certain distance, that is, the pull rod rack 521 and the transmission gear 51 can be engaged with each other after the pull rod 52 is moved by a certain distance. The pull rod 52 with the structure can realize the effect that the locking of the positioning piece 53 to the dust barrel 10 is firstly released and then the transmission gear 51 is driven to rotate. When the pull rod 52 moves along the second position toward the first position, i.e., moves upward, the clamping teeth 532 are disengaged from the positioning groove 522, the hook 533 is disengaged from the bottom of the slide rail 13, and at this time, the transmission gear 51 is still located in the buffer slot 525 and is not engaged with the pull rod rack 521, so that the pull rod 52 does not drive the transmission gear 51 to rotate, and the dust bucket 10 does not move relative to the machine body assembly 40. When the pull rod 52 continues to move upwards, at this time, the pull rod rack 521 is meshed with the transmission gear 51, and the pull rod 52 can drive the transmission gear 51 to rotate, so as to drive the dust barrel 10 to move.

Further, in order to protect the transmission gear 51 and the positioning member 53 from interference caused by other components, referring to fig. 2, in the embodiment of the present invention, the housing assembly 40 further includes a housing cover 404, and the housing cover 404 is connected to the housing assembly 40 and forms an installation cavity. The transmission gear 51 and the positioning piece 53 are both positioned in the mounting cavity, and a through hole 4041 for extending the transmission gear 51 and the positioning piece 53 is arranged on the machine body cover plate 404. The pull rod 52 extends into the mounting cavity and is connected with the transmission gear 51 and the positioning piece 53. The housing groove 41 can be covered by the housing cover 404 while protecting the transmission gear 51 and the positioning member 53, so as to prevent other parts of the housing assembly 40 from being exposed.

Further, referring to fig. 5 and fig. 7 in conjunction with fig. 2 and fig. 10, a limiting groove 526 extending along the length direction is provided on a side of the pull rod 52 facing the body cover 404 to limit the moving distance of the pull rod 52. The body cover 404 is provided with a limiting block 4042 corresponding to the limiting groove 526, and the limiting block 4042 extends into the limiting groove 526 to limit the moving distance of the pull rod 52. When the pull rod 52 moves upwards, the limiting block 4042 can be abutted on the groove wall below the limiting groove 526, so that the maximum distance of the upward movement of the pull rod 52 is limited, when the pull rod 52 moves downwards, the limiting block 4042 can be abutted on the groove wall above the limiting groove 526, so that the maximum distance of the downward movement of the pull rod 52 is limited, and the situation that the pull rod 52 moves upwards and downwards, and the transmission gear 51 and the positioning piece 53 are separated from each other to influence the opening of the bottom cover 30 is avoided.

Further, the body cover 404 is provided with an unlocking trigger 42 at a position corresponding to the latch assembly 20. The machine body cover 404 can be used as a part of the machine body assembly 40, two opposite sides of the machine body cover 404 are respectively provided with a gear groove and a locking groove, the machine body cover 404 is covered with a transmission gear 51 and a positioning piece 53 through the gear groove, the transmission gear 51 and the positioning piece 53 can act in the gear groove, and the groove wall of the gear groove is provided with a through hole 4041. The body cover 404 is used for locking the locking assembly 20 through the locking groove cover, the locking assembly 20 can act in the locking groove, and the unlocking trigger piece 42 is arranged in the locking groove. The latch assembly 20 and the positioning piece 53 of the transmission gear 51 can be separated by the machine body cover 404, so that mutual interference is avoided during the action.

In addition to the above manner, the unlocking assembly 50 may be further implemented in a manner that, referring to fig. 15 and 16, the unlocking assembly 50 includes an unlocking push rod 55, where the unlocking push rod 55 is fixedly connected to the dust bucket 10, for example, the unlocking push rod 55 may be fixedly connected to the dust bucket 10 by a screw 56, and the unlocking push rod 55 may drive the dust bucket 10 to move relative to the machine body assembly 40. In this way, the dust bucket 10 does not need to be provided with the slide rail 13, and the latch assembly 20, the bottom cover 30 and the body assembly 40 are arranged in the same manner as the above embodiments except for the implementation of the unlocking assembly 50.

Referring to fig. 15 and 16, the dust bucket 10 is located at the first position, and at this time, the bottom cover 30 is engaged with the latch assembly 20 and covers the dust outlet 11. The user can normally perform a cleaning operation, such as a dust suction operation, using the cleaning apparatus, and the sucked dust falls into the dust bucket 10.

When cleaning the dust barrel 10 is required, referring to fig. 17 to 20, the user can move downward through the unlocking push rod 55 to drive the dust barrel 10 to move from the first position to the second position relative to the machine body assembly 40, and when the dust barrel 10 moves relative to the machine body assembly 40, the unlocking trigger 42 can trigger the lock catch assembly 20 to unlock, at this time, the bottom cover 30 is unlocked and can rotate relative to the dust barrel 10 around the hinged connection, the dust outlet 11 can be opened by the bottom cover 30, and the open state of the bottom cover 30 can be referred to fig. 22. After the bottom cover 30 is opened, the dust in the dust bucket 10 can be poured out of the dust bucket 10 to complete cleaning of the dust bucket 10. Of course, when the dust bucket 10 moves relative to the machine body assembly 40, the scraping strip 12 also moves relative to the separator 402, and during the movement, the dust and other substances on the outer wall of the separator 402 can be scraped off the outer wall of the separator 402 to be poured out from the dust outlet 11.

Further, when the dust bucket 10 is located at the first position, in order to lock the relative position between the dust bucket 10 and the body assembly 40, see fig. 15 and 16, the unlocking push rod 55 includes a push rod main body 551 and a rotating rod 552. One end of the push rod body 551 is connected to the dust barrel 10, and the other end is rotatably connected to the rotating rod 552. When the dust bucket 10 is located at the first position, the rotating rod 552 can rotate relative to the push rod main body 551 and is connected to the machine body assembly 40. Since the suction unit 401 restricts the dust barrel 10 from moving upward, when the rotating lever 552 is coupled to the body unit 40, the dust barrel 10 is restricted from moving downward, and the suction unit 401 is engaged to ensure a relatively stable position between the dust barrel 10 and the body unit 40.

When the dust barrel 10 needs to be cleaned, referring to fig. 17 and 18, the rotating rod 552 can be separated from the machine body assembly 40, then the rotating rod 552 is rotated relative to the push rod body 551 to form a straight rod with the push rod body 551, then the user can push the rotating rod 552 downwards, the push rod body 551 is driven to move by the rotating rod 552, and the dust barrel 10 is driven to move relative to the machine body assembly 40 by the push rod body 551. Referring to fig. 19 and 20, when the dust bucket 10 is moved to the second position, the unlocking trigger 42 triggers the latch assembly 20 to unlock, so that the bottom cover 30 is opened. In order to prevent the dust barrel 10 from moving in place relative to the machine body assembly 40, the bottom cover 30 is not opened, and after the unlocking push rod 55 drives the dust barrel 10 to move to the second position relative to the machine body assembly 40, the unlocking push rod 55 can further drive the dust barrel 10 to move relative to the machine body assembly 40, so that the lock catch assembly 20 completely moves out of the accommodating groove 41, and the lock catch assembly 20 is separated from the bottom cover 30, so that the bottom cover 30 is opened. Of course, when the latch assembly 20 is not required to be moved out of the accommodating groove 41, the latch assembly 20 may not be completely moved out of the accommodating groove 41 when the latch assembly 20 and the bottom cover 30 are also enabled.

With continued reference to fig. 18, one way to connect the rotating rod 552 and the machine body assembly 40 is to provide the machine body assembly 40 with a fixing slot 45, a first fixing portion 46 is provided in the fixing slot 45, a second fixing portion is provided on the rotating rod 552, the rotating rod 552 can be accommodated in the fixing slot 45, and the first fixing portion 46 is connected with the second fixing portion. The first fixing portion 46 and the second fixing portion may be a limiting protrusion and a limiting groove, for example, the rotating rod 552 is provided with a limiting protrusion, the fixing groove 45 is provided with a limiting groove, and when the rotating rod 552 is accommodated in the fixing groove 45, the limiting protrusion is connected with the limiting groove so as to fix the rotating rod 552 in the fixing groove 45. After the rotating rod 552 is fixed, the relative position of the dust bucket 10 and the machine body assembly 40 can be limited.

Further, to limit the movement distance of the push rod body 551, the body assembly 40 is provided with a limiting structure to limit the movement distance of the unlocking push rod 55 from the first position to the second position. The limiting structure may refer to the implementation manner of the limiting groove 526 and the limiting block 4042 in the above embodiment, for example, the push rod main body 551 is provided with the limiting groove 526, the body assembly 40 is provided with the limiting block 4042, and the limiting block 4042 extends into the limiting groove 526 to limit the moving distance of the unlocking push rod 55.

Accordingly, in conjunction with fig. 1 to 22, an embodiment of the present invention further provides a dust collector, including: the dust bucket 10, the body assembly 40 and the unlocking assembly 50.

The bottom of the dust barrel 10 in the axial direction is provided with a dust outlet 11, the dust barrel 10 is provided with a lock catch assembly 20 and a bottom cover 30, and the bottom cover 30 is clamped with the lock catch assembly 20 to cover the dust outlet 11.
