Usually, a space for a handhold position is reserved on the side of the dust box close to the main machine, so that the user can touch the connecting structure between the dust box and the main machine to disassemble and assemble the dust box and the main machine. It can be understood that the handhold position needs to occupy a certain space, which reduces the space utilization rate of the dust box and is not conducive to the miniaturization design of the floor sweeping machine.

[0040] In addition, the terms "first", "second", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an ordered ranking of the indicated technical features. Thus, features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0041] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be directly above or obliquely above the first feature, or only indicate that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature can be directly below or obliquely below the first feature, or only indicate that the horizontal height of the first feature is less than that of the second feature.

[0043] As shown in Figure 1 A Cartesian coordinate system is established, the length direction of the dust box is parallel to the direction indicated by the x-axis, the width direction of the dust box is parallel to the direction indicated by the y-axis, and the height direction of the dust box is parallel to the direction indicated by the z-axis. It can be understood that the above definition is only for the purpose of understanding the relative position relationship of each part of the dust box, and should not be understood as a limitation of the present application.

[0044] A dust box is provided in the embodiment, which can be used in a surface cleaning device. During the operation of the surface cleaning device, the dust box can be used to store dirt.

[0045] As shown in Figures 1 to 3 The dust box can include a shell assembly 100, a plug-in buckle 200, an execution buckle 300 and a transmission assembly 400.

[0046] The shell assembly 100 can include a dirt discharge channel 112 in communication with the outside. When the surface cleaning device enters the base station (not shown), the dirt in the dust box can be transported to the dust collecting bucket of the base station through the dirt discharge channel 112.

[0047] AgainFigure 4 and Figure 5 The insertion buckle 200 and the execution buckle 300 are both floatingly installed in the shell assembly 100, and the floating direction of the insertion buckle 200 and the floating direction of the execution buckle 300 are parallel.

[0048] In the embodiment, one end of the insertion buckle 200 can be telescopically arranged relative to one side of the shell assembly 100, that is, the one end of the insertion buckle 200 can be extended out of the one side of the shell assembly 100 or retracted into the shell assembly 100. When the dust box is assembled to the main machine (not shown in the figure) of the surface cleaning device, the one end of the insertion buckle 200 extended out of the shell assembly 100 can be inserted into the corresponding slot of the main machine, so as to realize the detachable connection of the dust box and the main machine.

[0049] One end of the execution buckle 300 can be telescopically arranged relative to the pollution discharge channel 112, that is, the one end of the execution buckle 300 can be extended out of the pollution discharge channel 112 or retracted into the shell assembly 100.

[0050] The transmission assembly 400 can be drivingly connected between the execution buckle 300 and the insertion buckle 200, so as to realize the linkage between the execution buckle 300 and the insertion buckle 200. Specifically, when the one end of the execution buckle 300 close to the pollution discharge channel 112 is retracted into the shell assembly 100, the insertion buckle 200 can also be retracted into the shell assembly 100 through the transmission assembly 400, so as to realize the unlocking between the insertion buckle 200 and the main machine, and facilitate the disassembly of the dust box from the main machine.

[0051] In specific applications, when the user needs to disassemble the dust box from the main machine, the user's fingers can be inserted into the pollution discharge channel 112 to press the execution buckle 300 to retract into the shell assembly 100, thereby driving the insertion buckle 200 to retract into the shell assembly 100, so that the dust box is unlocked from the main machine, and the dust box can be taken off from the main machine.

[0052] In the present application, the pollution discharge channel 112 is used as a buckle position to control the insertion buckle 200 through the execution buckle 300, without reserving an additional buckle position on the side of the shell assembly 100 close to the main machine for the user to operate the insertion buckle 200, so that the space of the dust box can be saved. Therefore, the dust box provided by the present application can significantly improve the space utilization rate, so as to reserve more space for storing dirt or other substances, etc., and is beneficial to the miniaturization design of the surface cleaning device and improves the user experience.

[0053] As Figure 1 and Figure 2As shown, further, in some embodiments, the shell assembly 100 can include a main shell 110, an adapter shell 120, and a cover plate 130. Among them, the main shell 110 can be configured with a dust collecting cavity 111, which can be used to store dirt. A dirt discharge channel 112 can be provided at one end of the main shell 110 and communicate with the dust collecting cavity 111. The end of the dirt discharge channel 112 away from the dust collecting cavity 111 is an open end 1121, which can be used to communicate with the base station so as to discharge the dirt in the dust collecting cavity 111. In addition, part of the dirt discharge channel 112 can be a notch structure 1122, that is, the inner surface of the dirt discharge channel 112 is generally in a U-shaped structure.

[0054] The adapter shell 120 can be fixedly connected to the end of the main shell 110 close to the dirt discharge channel 112 by screw connection, clamping or adhesion, etc. And the adapter shell 120 can be located on the side of the main shell 110 close to the notch structure 1122 in the dirt discharge channel 112. In the embodiment, the adapter shell 120 can cover at least the notch structure 1122 of the dirt discharge channel 112 and close the notch structure 1122 of the dirt discharge channel 112.

[0055] Further combined Figure 3 , the adapter shell 120 away from the main shell 110 can be provided with a mounting cavity 121. The side of the mounting cavity 121 away from the main shell 110 is an open structure, and the cover plate 130 can close the open structure of the mounting cavity 121.

[0056] Further combined Figure 4 and Figure 5 , the plug-in buckle 200 and the execution buckle 300 can be floatingly installed in the mounting cavity 121. And the floating direction of the plug-in buckle 200 and the execution buckle 300 is parallel to the height direction of the dust box. In some embodiments, one end of the plug-in buckle 200 can be provided through the cover plate 130 and can be telescopically arranged relative to the side of the cover plate 130 away from the main shell 110. Correspondingly, the cover plate 130 can be provided with a first through hole 131 communicating with the mounting cavity 121, and the plug-in buckle 200 can be slidably provided through the first through hole 131.

[0057] One end of the execution buckle 300 can be provided through the adapter shell 120 and can be telescopically arranged relative to the side of the adapter shell 120 close to the dirt discharge channel 112. Correspondingly, the adapter shell 120 can be provided with a second through hole 122 communicating the mounting cavity 121 and the dirt discharge channel 112. The execution buckle 300 can be slidably provided through the second through hole 122.

[0058] As shown, Figures 3 to 6 , the plug-in buckle 200 can include an integral plug-in block 210 and a limiting flange 220. Among them, the plug-in block 210 can be slidably provided through the first through hole 131, and the shape of the first through hole 131 can be adapted to the shape of the plug-in block 210, so that the plug-in block 210 can be smoothly telescoped relative to the first through hole 131.

[0059] The limiting flange 220 can be located at one end of the mating block 210 near the mounting cavity 121. The limiting flange 220 can also protrude radially from the periphery of the mating block 210. In this embodiment, the outer diameter of the limiting flange 220 can be larger than the diameter of the first through hole 131. Therefore, the end of the mating buckle 200 near the limiting flange 220 can be confined within the mounting cavity 121, preventing the mating buckle 200 from disengaging from the mounting cavity 121, i.e., preventing the mating buckle 200 from separating from the housing assembly 100. It is understood that when both the limiting flange 220 and the first through hole 131 are non-circular structures, the outer diameters of both refer to their corresponding circumscribed circle diameters.

[0060] like Figure 4 and Figure 5 As shown, in some embodiments, the cross-sectional area of ​​the first through hole 131 near the mounting cavity 121 may be larger than the cross-sectional area of ​​the first through hole 131 away from the mounting cavity 121. The cross-sectional area of ​​the first through hole 131 refers to the cross-sectional area perpendicular to the height of the dust box. That is, the first through hole 131 generally has a tapering structure from the end near the mounting cavity 121 to the end away from the mounting cavity 121.

[0061] Correspondingly, the cross-sectional area of ​​the end of the mating block 210 near the limiting flange 220 can be larger than the cross-sectional area of ​​the end of the mating block 210 away from the limiting flange 220. Here, the cross-sectional area of ​​the mating block 210 refers to the cross-sectional area perpendicular to the height of the dust box. Accordingly, the end of the mating block 210 away from the limiting flange 220 can be designed with a tapered structure adapted to the first through hole 131. Therefore, when the mating block 210 extends or retracts relative to the first through hole 131, the extension and retraction stroke of the mating block 210 can be further limited, preventing the mating block 210 from detaching from the mounting cavity 121.

[0062] like Figure 3 , Figure 4 and Figure 7 As shown, the adapter shell 120 also includes a limiting buckle 124, which protrudes from the base plate 123 of the mounting cavity 121. The end of the limiting buckle 124 away from the base plate 123 can be located on the floating path of the limiting flange 220. When the latch 200 extends relative to one side of the cover plate 130, the limiting buckle 124 abuts against the side of the limiting flange 220 near the latching block 210 to limit the floating stroke of the latch 200 and further prevent the latch 200 from disengaging from the mounting cavity 121. The number of limiting buckles 124 can be set as needed. For example, in some embodiments, four limiting buckles 124 can be provided, symmetrically distributed around the periphery of the latch 200.

[0063] In other embodiments, the limit buckle 124 may be set to one, two, three or five, etc.

[0064] In this embodiment, there may be a height difference between the limiting buckle 124 and the cover plate 130, that is, there is a gap between the limiting buckle 124 and the cover plate 130. When the snap fastener 200 extends out relative to one side of the cover plate 130, a gap may also be reserved between the limiting flange 220 and the cover plate 130.

[0065] like Figures 3 to 6 As shown, the dust box also includes a first elastic element 510. The first elastic element 510 can abut between the adapter housing 120 and the latch 200, and can be used to drive the latch 200 to extend relative to the side of the cover plate 130 away from the main housing 110, even if the latch 200 extends out of the housing assembly 100.

[0066] Specifically, one end of the first elastic member 510 may abut against the base plate 123. The other end of the first elastic member 510 may abut against the end of the mating block 210 near the limiting flange 220. When the mating block 210 extends relative to the housing assembly 100, the first elastic member 510 may be in a naturally extended state or a compressed state.

[0067] Understandably, when the latch 200 retracts into the mounting cavity 121, the first elastic element 510 can compress and store a certain amount of elastic potential energy. When the user releases the actuator 300, the latch 200 can be reset under the action of the first elastic element 510 and extend relative to the side of the cover plate 130 away from the main housing 110. In some embodiments, the first elastic element 510 may be a spring.

[0068] In other embodiments, the first elastic element 510 may also be a sheet, a flexible column, or other structure.

[0069] In some embodiments, a guide post 211 may be provided at one end of the mating block 210 near the limiting flange 220. One end of the first elastic member 510 near the mating buckle 200 may be sleeved on the periphery of the guide post 211 to prevent tilting misalignment between the first elastic member 510 and the mating buckle 200, and to ensure that the first elastic member 510 provides a stable and reliable driving force for the mating buckle 200.

[0070] Combined again Figure 7 Furthermore, the guide post 211 is also provided with a guide groove 2111 opposite to the base plate 123. A guide block 127 may be protruded on the base plate 123, and the guide block 127 can be slidably inserted into the guide groove 2111. Thus, through the cooperation of the guide block 127 and the guide groove 2111, the floating of the snap fastener 200 can be guided, preventing the snap fastener 200 from getting stuck due to tilting.

[0071] like Figure 2 ,Figures 4 to 6 As shown, the actuator 300 may include an actuator body 310. One end of the actuator body 310 is slidably inserted into the second through hole 122. The inner wall of the second through hole 122 may be in contact with the peripheral surface of the actuator body 310 or have a small gap, so that the actuator body 310 can float smoothly.

[0072] Additionally, a stepped structure may be provided on the periphery of the actuator body 310, forming a stepped surface 311. Along the height direction of the dust box, the stepped surface 311 may be approximately located in the middle of the actuator body 310, and may face the side of the second through hole 122. In the embodiment, the outer diameter of the stepped surface 311 may be larger than the diameter of the second through hole 122. When the actuator body 310 extends relative to the drain channel 112, the stepped surface 311 may abut against the bottom plate 123 of the adapter shell 120 to confine the other end of the actuator body 310 within the mounting cavity 121, preventing the actuator 300 from separating from the housing assembly 100. It is understood that when both the stepped surface 311 and the second through hole 122 are non-circular structures, the outer diameter of the stepped surface 311 and the diameter of the second through hole 122 both refer to their corresponding circumscribed circle diameters.

[0073] In some embodiments, the end face of the actuator body 310 near the sewage channel 112 may be provided with anti-slip texture to prevent the user from slipping when operating the actuator 300.

[0074] like Figures 3 to 6 As shown, the dust box also includes a second elastic element 520. The second elastic element 520 can abut between the actuator body 310 and the cover plate 130. The second elastic element 520 can be used to drive the actuator body 310 to extend relative to the drain channel 112.

[0075] Specifically, one end of the second elastic element 520 abuts against the end of the actuator body 310 near the mounting cavity 121. The other end of the second elastic element 520 may abut against the cover plate 130. When the actuator body 310 extends relative to the drain channel 112 and the stepped surface 311 abuts against the base plate 123, the second elastic element 520 may be in a naturally extended state or a compressed state. In some embodiments, the second elastic element 520 may be a spring.

[0076] In other embodiments, the second elastic element 520 may also be a structure such as a spring sheet or a flexible column.

[0077] When the user presses the actuator body 310, the second elastic element 520 is compressed and stores a certain amount of elastic potential energy. When the user releases the actuator body 310, the actuator body 310 can be reset under the action of the second elastic element 520 and extend relative to the drain channel 112.

[0078] In addition, in some embodiments, the execution buckle body 310 is further provided with a limiting groove 312 at one end close to the installation cavity 121. The second elastic member 520 close to one end of the execution buckle body 310 can be accommodated in the limiting groove 312, and the second elastic member 520 can be prevented from being inclined and misaligned relative to the execution buckle body 310, so as to ensure that the second elastic member 520 can provide a stable and reliable driving force for the execution buckle body 310.

[0079] As shown in Figure 3 , Figure 6 and Figure 7 , in some embodiments, the bottom plate 123 is further provided with two opposite guide plates 125 at one side close to the installation cavity 121. The two guide plates 125 can cooperatively form a guide groove 126, which can be parallel to the height direction of the dust box. The guide groove 126 can be located at one side of the execution buckle 300. Correspondingly, the execution buckle 300 further includes a guide block 320. The guide block 320 can be protruded at one side of the execution buckle body 310 close to the guide groove 126, and one end of the guide block 320 away from the execution buckle body 310 can be slidably inserted into the guide groove 126 and can slide along the guide groove 126.

[0080] When the execution buckle body 310 floats relative to the shell assembly 100, the guide block 320 can cooperate with the guide groove 126 to provide a guide function for the execution buckle body 310, so as to prevent the execution buckle body 310 from being inclined and the like, so as to ensure that the execution buckle body 310 can smoothly float relative to the shell assembly 100.

[0081] In some embodiments, the guide groove 126 and the guide block 320 can be provided in pairs and can be provided in two pairs. Along the width direction of the dust box, the two pairs of guide grooves 126 and guide blocks 320 can be separately provided at two ends of the execution buckle body 310.

[0082] In other embodiments, the guide groove 126 and the guide block 320 can also be provided in one pair, three pairs or five pairs, etc. according to needs.

[0083] As shown in Figures 4 to 6 , in some embodiments, the transmission assembly 400 can include a transmission frame 410. The transmission frame 410 can be located between the plug-in buckle 200 and the execution buckle 300, and the transmission frame 410 can be rotatably installed in the installation cavity 121. In an embodiment, the rotation axis L of the transmission frame 410 can be parallel to the width direction of the dust box.

[0084] In addition, the transmission frame 410 further includes a first end 4101 and a second end 4102. The first end 4101 and the second end 4102 can be separately provided at two sides of the rotation axis L. Correspondingly, the transmission frame 410 can form a lever structure.

[0085] In some embodiments, the first end 4101 of the transmission frame 410 can be located at a side of the rotation axis L close to the execution buckle 300, and the first end 4101 of the transmission frame 410 can abut against an end of the execution buckle body 310 away from the pollution discharge channel 112. The second end 4102 of the transmission frame 410 can be located at a side of the rotation axis L close to the plug-in buckle 200, and the second end 4102 of the transmission frame 410 can abut against a side of the limiting flange 220 close to the plug-in block 210. In some embodiments, the transmission frame 410 can be used to realize linkage between the execution buckle 300 and the plug-in buckle 200.

[0086] When the user presses the execution buckle 300, the execution buckle 300 can be pushed to move towards the cover plate 130. In turn, the transmission frame 410 can be pushed to rotate, and the first end 4101 of the transmission frame 410 can be moved towards the cover plate 130. At the same time, the second end 4102 of the transmission frame 410 can be moved away from the cover plate 130, and the plug-in buckle 200 can be driven to move towards the bottom plate 123, so that the plug-in buckle 200 is retracted into the installation cavity 121, thereby facilitating separation of the main machine.

[0087] When the user releases the execution buckle 300, the execution buckle 300 and the plug-in buckle 200 can be reset under the action of the corresponding elastic members, and at the same time, the transmission frame 410 can also be reset to rotate.

[0088] In some embodiments, the transmission frame 410 can include an integral rod portion 411 and two connecting arms 412. The rod portion 411 can extend along the width direction of the dust box.

[0089] An avoiding groove 313 can be formed at an end of the execution buckle body 310 close to the cover plate 130, and the avoiding groove 313 can be located at a side of the execution buckle body 310 close to the transmission frame 410. In some embodiments, the rod portion 411 of the transmission frame 410 can be accommodated in the avoiding groove 313 and can abut against the groove bottom of the avoiding groove 313. In this way, the internal space of the installation cavity 121 can be saved, thereby improving the space utilization of the dust box.

[0090] The two connecting arms 412 can be respectively arranged at two ends of the rod portion 411. The two connecting arms 412 can respectively extend from the first end 4101 to the second end 4102. The two connecting arms 412 can be respectively arranged at two sides of the plug-in buckle 200. In addition, the two connecting arms 412 can respectively protrude the abutting protrusions 413 at a side close to the plug-in buckle 200. In the width direction of the dust box, one abutting protrusion 413 can abut against one end of the limiting flange 220, and the other abutting protrusion 413 can abut against the other end of the limiting flange 220.

[0091] In this embodiment, the limiting flange 220 and the cover plate 130 are spaced apart, thereby providing a receiving space for the abutting protrusion 413 so that the abutting protrusion 413 abuts against the side of the limiting flange 220 near the insertion block 210, thereby pushing the insertion buckle 200 to move.

[0092] In other embodiments, the end of the connecting arm 412 away from the rod 411 may directly abut against the side of the limiting flange 220 near the insertion block 210.

[0093] It is understood that the transmission frame 410 also includes two rotating shafts 414. The two rotating shafts 414 can be respectively disposed on the opposite sides of the two connecting arms 412. The two rotating shafts 414 can be arranged along the rotation axis L of the transmission frame 410. In the embodiment, the end of the rotating shaft 414 away from the connecting arm 412 can be rotatably connected to the housing assembly 100. Specifically, the end of the rotating shaft 414 away from the connecting arm 412 can be rotatably connected to the connection between the cover plate 130 and the adapter shell 120.

[0094] like Figure 3 and Figure 8 As shown, in some embodiments, the transmission assembly 400 may include a first rack 421, a second rack 422, and a gear 423. The first rack 421 may be fixedly mounted on the side of the actuating latch 300 near the engaging latch 200. The second rack 422 may be fixedly mounted on the side of the engaging latch 200 near the actuating latch 300. The gear 423 may be rotatably mounted in the mounting cavity 121. The gear 423 may be located between the first rack 421 and the second rack 422, and the gear 423 may mesh with both the first rack 421 and the second rack 422.
