As shown in fig. 1, an embodiment provides a dust box structure 1000 that can be used in a surface cleaning apparatus. It will be appreciated that the dirt tray structure 1000 can be used to collect dirt swept by the surface cleaning apparatus during operation of the surface cleaning apparatus.

As shown in fig. 1 and 2, the dirt box structure 1000 can include a dirt box assembly 100 and a first mating buckle 200. Wherein the first mating fastener 200 is floatingly mounted to one side of the dust box assembly 100, i.e., the first mating fastener 200 can be close to and away from the dust box assembly 100. In an embodiment, the first mating buckle 200 may include a first locked state and a first unlocked state.

When the first engaging latch 200 is in the first locked state, the first engaging latch 200 may protrude from a side of the dust box assembly 100 and may be used to limit a host computer connected to the surface cleaning apparatus. Thus, the connection between the dust box structure 1000 and the host can be realized, and the dust box structure 1000 is fixed relative to the host.

When the first mating buckle 200 is in the first unlocked state, the first mating buckle 200 can be retracted relative to the dust box assembly 100 and can be disengaged from the host computer. Therefore, the unlocking between the dust box structure 1000 and the host can be realized, and the dust box structure 1000 is conveniently detached from the host.

It is understood that, in the present application, the first mating buckle 200 is floatingly mounted on the dust box assembly 100, and the first mating buckle 200 can be switched between the first locked state and the first unlocked state by driving the first mating buckle 200 to float with respect to the dust box assembly 100. In this process, the first engaging buckle 200 is not subjected to the acting force for driving the first engaging buckle to deform, so that the problem that the first engaging buckle 200 is broken due to stress deformation can be avoided, the possibility that the first engaging buckle 200 is damaged can be reduced, and the service life of the first engaging buckle 200 is prolonged.

As shown in fig. 1-3, the dust box assembly 100 may include a dust box 110 and an adaptor housing 120.

The adapting shell 120 can be fixedly connected to one side of the dust collecting box 110 by means of bonding, clipping, or screwing. A first mounting groove 121 may be formed at a side of the adaptor shell 120 away from the dust box 110. One end of the first mounting groove 121 remote from the dust box 110 may be open. The first engaging button 200 is floatingly mounted in the first mounting groove 121, and is retractable with respect to an opening of one end of the first mounting groove 121, which is far from the dust box 110.

In an embodiment, the dust box assembly 100 can include an assembly orientation. The dust box assembly 100 is removable from the host computer at a corresponding location along the assembly direction. The floating direction of the first coupling buckle 200 may be perpendicular to the assembly direction of the dust box assembly 100. When the first engaging button 200 is in the first locking state, one end of the first engaging button 200, which is far away from the dust collecting box 110, may protrude from an opening of one end of the first mounting groove 121, which is far away from the dust collecting box 110, and may be inserted into a slot limited at a corresponding position of the host to limit the dust box structure 1000 to move along the assembling direction, thereby realizing the fixed mounting of the dust box structure 1000 to the host.

As shown in fig. 2 to 4, the first mating buckle 200 may include a first mating buckle body 210 and a first insertion portion 230. The first inserting portion 230 may be protruded from an end of the first engaging button body 210 away from the dust collecting box 110. When the first engaging buckle 200 is in the first locking state, the first inserting portion 230 may protrude relative to the first mounting groove 121 and be inserted into a slot located at a corresponding position of the host. When the first engaging button 200 is in the first unlocking state, the first inserting portion 230 can be received in the first mounting groove 121.

In some embodiments, the dust box structure 1000 further includes a first elastic member 410, and the first elastic member 410 can be received in the first mounting groove 121. Specifically, one end of the first elastic member 410 may abut against a groove bottom of one end of the first mounting groove 121 close to the dust box 110. The other end of the first elastic member 410 can abut against one end of the first engaging buckle body 210 close to the dust collecting box 110. In an embodiment, the first elastic member 410 can drive the first fitting buckle 200 to move in a direction away from the dust collecting box 110, so that the first insertion part 230 protrudes relative to the first mounting groove 121. When the first coupling buckle 200 is in the first locked state, the first elastic member 410 may be in a natural extension state or a compression state. In some embodiments, the first elastic member 410 may be a spring.

In other embodiments, the first elastic element 410 may also be a spring or a flexible block.

As shown in fig. 3 and 4, the adaptor housing 120 further includes a positioning groove 122 communicating with the first mounting groove 121. The positioning groove 122 may be formed by a groove bottom of the first mounting groove 121 depressed in a direction approaching the dust box 110.

In an embodiment, an end of the first elastic element 410 close to the bottom of the first mounting groove 121 can be received in the positioning slot 122. Therefore, the positioning groove 122 can provide radial limitation for the first elastic element 410, and the first elastic element 410 is prevented from randomly shaking relative to the transfer case 120, so as to ensure that the first elastic element 410 provides stable and reliable driving force for the first mating buckle 200.

Correspondingly, the first mating buckle 200 further includes a positioning post (i.e., the first positioning post 220). The first positioning pillar 220 can be protruded from one side of the first engaging button body 210 near the bottom of the first mounting groove 121. In an embodiment, an end of the first elastic element 410 close to the first engaging buckle 200 may be sleeved on a circumference of the first positioning post 220. Therefore, the first positioning post 220 can provide radial position limitation for the first elastic element 410, and the first elastic element 410 is prevented from freely swinging relative to the first mating buckle 200, so as to ensure that the first elastic element 410 can provide stable and reliable driving force for the first mating buckle 200.

As shown in fig. 3 and 4, the adapter housing 120 further includes a first limit groove 123. The first position-limiting groove 123 may be opened on a side wall of the first mounting groove 121, and an extending direction of the first position-limiting groove 123 may be parallel to a floating direction of the first engaging buckle 200. Correspondingly, the first engaging fastener 200 further includes a first limiting block 241. The first limiting block 241 can be located on a side surface of the first engaging buckle body 210, and the first limiting block 241 can be slidably mounted in the first limiting groove 123. In an embodiment, the first limiting groove 123 may cooperate with the first limiting block 241 to limit the floating stroke of the first engaging buckle 200. When the first engaging button 200 is in the first locking state, the first limiting block 241 can abut against the sidewall of the first limiting groove 123 far away from the end of the dust collecting box 110, so as to limit the first engaging button 200 from being separated from the first mounting groove 121, and thus the first engaging button 200 can be prevented from being separated from the adaptor shell 120.

In some embodiments, the first stopper 241 may be connected to the first mating buckle body 210 by a resilient arm 242. Specifically, one end of the elastic arm 242 may be fixedly connected to one end of the first engaging buckle body 210 away from the dust collecting box 110 by way of integral molding. The elastic arm 242 may extend in a direction to approach the dust box 110 in the floating direction of the first coupling button 200. The first limiting block 241 can be fixedly connected to one end of the elastic arm 242 close to the dust collecting box 110 by way of integral molding, and the first limiting block 241 is located at one side of the elastic arm 242 far from the first matching buckle body 210, so that the first limiting block 241 is matched with the first limiting groove 123 to provide a limiting function.

Referring to fig. 2, in an embodiment, the first engaging button 200 may be made of plastic. When assembling the dust box structure 1000, the elastic arm 242 can elastically deform to assemble the first limiting block 241 in the first limiting groove 123, and also to assemble the first engaging buckle 200 in the first mounting groove 121.

As shown in fig. 4 and 5, the adaptor shell 120 further includes a first guide rail 124 parallel to the floating direction of the first coupling buckle 200. Correspondingly, the first engaging buckle 200 further includes a second guide rail 250 parallel to the floating direction of the first engaging buckle 200. The second guiding rail 250 can be disposed around the first buckle body 210 and can be matched with the first guiding rail 124. In an embodiment, the first guide rail 124 and the second guide rail 250 may be slidably engaged to provide a guiding function for the floating of the first engaging latch 200, so as to prevent the first engaging latch 200 from being tilted relative to the adaptor shell 120 to cause the problem of jamming, and further ensure the smooth switching of the first engaging latch 200 between the first locked state and the first unlocked state. In some embodiments, the first rail 124 and the second rail 250 may be similar in structure and may each be formed by two spaced apart guide bars parallel to the floating direction, wherein the guide bars of one rail may cooperate to form a guide slot parallel to the floating direction and the other rail may slidably fit within the guide slot.

Referring to fig. 2 and 3, when the first engaging button 200 is switched from the first locking state to the first unlocking state, the first engaging button 200 can be pressed against the elastic force of the first elastic member 410, so that the first engaging button 200 moves toward the dust collecting box 110, and the first inserting portion 230 of the first engaging button 200 can be separated from the host and contained in the first mounting 121, so as to conveniently detach the dust box structure 1000 from the host. When the user releases the first engaging latch 200, the first engaging latch 200 can be switched to the first locking state by the elastic force of the first elastic member 410.

As shown in fig. 1, 2 and 6, the interior of the dust box 110 is hollow and may form a dust chamber 111. One end of the dust collection box 110 may be opened with a first through hole 112 communicating with the dust collection chamber 111, and the first through hole 112 may be used as an input port of the dust collection box 110. The other end of the dust collection box 110 can be opened with a second through hole 113 communicated with the dust collection cavity 111, and the second through hole 113 can be used as an output port of the dust collection box 110.

Dust box structure 1000 is applied to a surface cleaning apparatus that, when providing a cleaning function, carries dirt with flowing gas through first through-hole 112 into dust collection chamber 111. When the surface cleaning apparatus enters the base station, dirt in the dust collection chamber 111 can be transported into the dust collection bucket of the base station through the second through hole 113. It is understood that the door panel 500 may be installed at the second through hole 113, and may be used to control the opening and closing of the second through hole 113. When the surface cleaning apparatus provides a cleaning function, the second through hole 113 may be closed by the door panel 500 to prevent air leakage from affecting the suction force of the surface cleaning apparatus.

As shown in fig. 2 and 6, the dust box 110 may include a bottom plate 116, and the bottom plate 116 may be located at a side of the dust box 110 away from the adaptor shell 120. In one embodiment, the bottom plate 116 may be gradually inclined away from the adaptor shell 120 from an end near the first through hole 112 to an end near the second through hole 113, so that the dirt may be collected toward the second through hole 113 under the flow guiding effect of the bottom plate 116.

In addition, the dust collecting box 110 further comprises two symmetrical guide side plates 117. The distance between the two flow guide side plates 117 can gradually decrease from the end near the first through hole 112 to the end near the second through hole 113. Accordingly, the dirt in the dust collecting chamber 111 can be further guided to be collected to a position close to the second through hole 113. Further, the dust collecting barrel in the base station can conveniently suck away the dirt in the dust collecting box 110. In some embodiments, the two flow guiding side plates 117 may be symmetrical curved plates, and the two flow guiding side plates 117 may be recessed away from each other. Therefore, dead angles in the dust collecting chamber 111 can be reduced, and the dirt in the dust collecting chamber 111 can be smoothly output.

As shown in fig. 1, 2 and 6, an opening structure 114 may be formed at a side of the dust box 110 adjacent to the adaptor shell 120. To avoid the opening structure 114, the adaptor shell 120 may be substantially U-shaped, and the adaptor shell 120 may be disposed on the periphery of the opening structure 114. In addition, the dust box assembly 100 further includes a cover plate 130 for covering the opening structure 114 of the dust box 110.

Referring again to fig. 7, the cover plate 130 may include a first end 1301 and a second end 1302. Wherein, the first end 1301 can be hinged to one end of the dust collection box 110 near the first through hole 112. The second end 1302 of the cover plate 130 can be detachably connected to the adaptor shell 120 through the second mating buckle 300. When cleaning or the like of dust collection chamber 111 is required, cover 130 may be flipped over to open opening structure 114. When the dust box assembly 100 is in normal use, the opening structure 114 can be closed by the cover plate 130, and the cover plate 130 is connected to the adapting shell 120, so that the cover plate 130 is relatively fixed with respect to the dust box 110.

In some embodiments, a side of the cover plate 130 away from the dust box 110 may be formed with a second mounting groove 131, and the second mounting groove 131 may be located at the second end 1302 of the cover plate 130. The second engaging button 300 is slidably mounted in the second mounting groove 131, and the sliding direction of the second engaging button 300 can be parallel to the direction from the first end 1301 to the second end 1302. When the cover plate 130 covers the opening structure 114, the second engaging button 300 can move close to or away from the position of the transition shell 120 opposite to the second engaging button 300 when sliding relative to the second mounting groove 131. In the embodiment, both the side of the second mounting groove 131 far away from the dust box 110 and the end of the second mounting groove 131 near the second end 1302 are open.

In some embodiments, the second mating buckle 300 may include a second locked state and a second unlocked state. When the second engaging latch 300 is in the second locking state, the second engaging latch 300 may protrude from an end of the second mounting groove 131 close to the second end 1302 and be connected to the adaptor shell 120 in a limiting manner. When the second mating buckle 300 is in the second unlocked state, the second mating buckle 300 can be separated from the adaptor shell 120 and retracted into the second mounting groove 131.

As shown in fig. 2, 5, 7, and 9, in some embodiments, the second mating buckle 300 may include a second mating buckle body 310 and a second socket 320. The second inserting portion 320 can be protruded from an end of the second engaging buckle body 310 near the second end 1302. An insertion groove 125 may be formed in the adaptor shell 120 at a position opposite to the second coupling buckle 300. When the cover plate 130 covers the opening structure 114, the insertion groove 125 may be opposite to the second insertion portion 320.

When the second engaging latch 300 is in the second locked state, the second inserting portion 320 protrudes from an end of the second mounting groove 131 close to the second end 1302, and is inserted into the inserting groove 125 of the adaptor shell 120 to limit the cover plate 130 to rotate around the first end 1301. When the second engaging button 300 is in the second unlocked state, the second engaging portion 320 can be disengaged from the engaging slot 125 and retracted into the second mounting slot 131, so that the user can pull the cover 130 to rotate to open the opening structure 114 of the dust collecting box 110.

In an embodiment, the dust box structure 1000 further includes a second elastic member 420. The second elastic member 420 can be accommodated in the second mounting groove 131, one end of the second elastic member 420 can abut against the sidewall of the second mounting groove 131 near the first end 1301, and the other end of the second elastic member 420 can abut against the end of the second buckle body 310 near the first end 1301. In one embodiment, the second elastic member 420 can be used to drive the second inserting portion 320 to protrude relative to the end of the second mounting groove 131 near the second end 1302. In an embodiment, when the second engaging fastener 300 is in the second locked state, the second elastic member 420 may be in a compressed state or a natural extension state. In some embodiments, the second elastic member 420 may be a spring.

In other embodiments, the second elastic member 420 may also be a spring or a flexible block.

In some embodiments, the second mating buckle 300 further includes a second positioning post 330, and the second positioning post 330 can be protruded from an end of the second mating buckle body 310 close to the first end 1301. One end of the second elastic member 420 close to the second engaging buckle 300 may be sleeved on the second positioning pillar 330. Therefore, the second positioning post 330 can provide radial position limitation for the second elastic member 420, and prevent the second elastic member 420 from freely swinging relative to the second mating buckle 300, so as to ensure that the second elastic member 420 provides stable and reliable driving force for the second mating buckle 300.

Referring to fig. 8, a second limiting groove 132 may be formed on a side wall of the second mounting groove 131, and an extending direction of the second limiting groove 132 may be parallel to a sliding direction of the second engaging buckle 300. Correspondingly, the second engaging fastener 300 may further include a second limiting block 340, the second limiting block 340 may be protruded from a side surface of the second engaging fastener body 310, and the second limiting block 340 may be disposed in cooperation with the second limiting groove 132. Specifically, the second stopper 340 is slidably assembled in the second stopper groove 132. It can be understood that the sliding direction of the second stopper 340 in the second stopper groove 132 is parallel to the sliding direction of the second fitting buckle 300. When the second engaging latch 300 is in the second locked state, the second stopper 340 can abut against a wall of the second stopper groove 132 near the second end 1302, so as to limit the second engaging latch 300 from being separated from the second mounting groove 131.

In some embodiments, the side wall of the second mounting groove 131 is further formed with a guide groove 133 parallel to the sliding direction of the second engaging button 300. The second engaging buckle 300 further includes a guiding rod 350 protruding from the side of the second engaging buckle body 310. The guide bar 350 is slidably installed in the guide groove 133. In an embodiment, the guiding rod 350 may cooperate with the guiding groove 133 to provide a guiding function for the sliding of the second engaging button 300, so as to prevent the second engaging button 300 from tilting relative to the cover plate 130, thereby reducing the probability of the second engaging button 300 being jammed.

When the second engaging latch 300 needs to be switched from the second locked state to the second unlocked state, the elastic force of the second elastic member 420 can be overcome, and the second engaging latch 300 is pushed toward the first end 1301, so that the second inserting portion 320 is separated from the inserting groove 125 and is retracted into the second installing groove 131. When the second engaging button 300 is switched to the second unlocking state, the user can pull the cover plate 130 smoothly to rotate to open the opening structure 114 of the dust collecting box 110. When the user releases the second engaging latch 300, the second engaging latch 300 can be switched from the second unlocked state to the second locked state by the second elastic member 420.

As shown in fig. 2 and 7, in some embodiments, the cover plate 130 further defines an air outlet 134 communicating with the dust collecting chamber 111. Specifically, air outlet 134 may be in communication with dust collection chamber 111 through opening structure 114. When the surface cleaning apparatus provides a cleaning function, airflow through dust collection chamber 111 may be delivered to the host computer sequentially through opening structure 114 and exhaust port 134. It will be appreciated that a screen 135 may be integrated into the cover plate 130 to filter the flow of air passing between the open structure 114 and the exhaust port 134.

Referring to fig. 6, in an embodiment, the dust box structure 1000 further includes a sealing ring 600 for sealing the cover plate 130 and the opening structure 114 to prevent air leakage, so as to ensure the suction force of the surface cleaning apparatus during cleaning and to make dirt be smoothly sucked into the dust collecting cavity 111. Illustratively, the opening structure 114 may be provided with a ring of support rim 115 protruding in the circumferential direction. Sealing ring 600 may be fixedly disposed on a side of support rim 115 remote from dust collection chamber 111. When the cover plate 130 covers the opening structure 114, the sealing ring 600 can be compressed between the cover plate 130 and the supporting rim 115. Wherein, the supporting rim 115 can be formed by extending the dust box 110 or the adaptor shell 120.

In one embodiment, the seal ring 600 may be made of ethylene-vinyl acetate copolymer, silicone, or rubber.
