Description

Technical Field

[0002] Cleaning robots with cleaning functions such as washing, mopping, and sweeping can replace users to perform cleaning tasks such as washing the floor, bringing many conveniences to users, and are therefore widely used. With the increase in user demand, user experience has become an important indicator for measuring the quality of cleaning robots. Cleaning robots equipped with rag trays usually face the situation where users need to disassemble and assemble the rag tray by themselves. As the disassembly and assembly of the rag tray by users is an important part of the interaction between users and cleaning robots, the ease of disassembly and assembly of the rag tray directly affects the user experience.

[0003] At present, the rag tray is usually installed by screws (such as cross-slot screws, hexagon screws, torx screws, etc.). When the rag tray needs to be disassembled, the user needs to prepare appropriate tools (such as screwdrivers, hexagon wrenches, etc.) to disassemble the rag tray. This means that the preparation and management of the corresponding tools will bring inconvenience to the user, and the screw locking method also brings the defects of time-consuming and labor-intensive disassembly and assembly process. The above factors make it inconvenient for users to disassemble and assemble the rag tray. Summary of the invention

[0034] The present application provides a cleaning device, which is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0035] See also Figure 1 , Figure 1 It is a schematic cross-sectional structure diagram of the first embodiment of the cleaning component of the present application. Figure 1 FIG. 2 shows that the cleaning assembly 10 of this embodiment is in a connected state with the positioning member 30 and the driving assembly 50 described below.

[0036] In one embodiment, the cleaning device may be a cleaning robot with a cleaning function. The cleaning device can move on the surface to be cleaned 20 by itself to clean the area where it passes. The surface to be cleaned 20 may be the ground, or the surface of other objects to be cleaned. Of course, in other embodiments of the present application, the cleaning device may also be a cleaning machine, a floor scrubber or other cleaning equipment, and the user holds the cleaning device and pushes the cleaning device to move on the surface to be cleaned 20, so that the cleaning device cleans the area where it passes. The embodiments of the present application are described using a cleaning robot as an example, which is only for the purpose of discussion and is not intended to be limiting.

[0037] Specifically, the cleaning device includes a device body, which can move on the surface to be cleaned 20 to clean the area it passes through. The device body can be provided with a driving mechanism such as a driving wheel and a driving track to drive the device body to move on the surface to be cleaned 20.

[0038] The cleaning device further includes a cleaning assembly 10. The cleaning assembly 10 includes a support 11 and a cleaning member 12. The support 11 is rotatably connected to the device body. The cleaning member 12 is disposed on the support 11 and can rotate with the support 11. The cleaning member 12 is used to clean the surface 20 to be cleaned. The support 11 is configured to be able to rotate relative to the device body around a rotation axis (such as Figure 1 The cleaning member 12 rotates by itself (shown by the dashed line O, the same below) to drive the cleaning member 12 to rotate synchronously to clean the surface 20 to be cleaned. The cleaning member 12 can be a rag, a brush, etc.

[0039] Please also read Figure 2 , Figure 2 yes Figure 1 A schematic structural diagram of the cleaning component A area is shown.

[0040] In one embodiment, the cleaning assembly 10 is detachably connected to the device body. The user can remove the cleaning assembly 10 for cleaning, maintenance or replacement of a new cleaning assembly 10, and then the user can install the cleaned, maintained or new cleaning assembly 10 back into the device body.

[0041] Specifically, the cleaning device further includes a first limiting structure and a second limiting structure. The first limiting structure is connected to the device body, and the second limiting structure is connected to the support member 11. One of the first limiting structure and the second limiting structure is a limiting surface 31, and the limiting surface 31 is arranged obliquely or parallel to the surface to be cleaned 20, and the other is a retractable limiting member 41. By retracting the limiting member 41, the second limiting structure can be moved to the side of the first limiting structure facing away from the surface to be cleaned 20, and by extending the limiting member 41, the limiting member 41 and the limiting surface 31 can cooperate to limit the cleaning component 10 from moving toward the surface to be cleaned 20.

[0042] In the above manner, the embodiment realizes the detachable design between the cleaning component 10 and the device body by cooperating with the retractable limiting member 41 and the limiting surface 31, replacing the prior art method of disassembling and assembling the rag plate by screw locking, avoiding the user from using auxiliary tools such as screwdrivers and hexagonal wrenches to disassemble and assemble the cleaning component 10. The embodiment can conveniently disassemble and assemble the cleaning component 10, thereby helping to improve the user experience.

[0043] In one embodiment, the first limiting structure is a limiting surface 31, and the second limiting structure corresponds to a limiting member 41. Specifically, the cleaning device further includes a positioning member 30. The positioning member 30 is disposed on the device body. The positioning member 30 has a limiting surface 31, and the limiting surface 31 faces away from the surface to be cleaned 20. The limiting member 41 is retractably disposed on the support member 11. The limiting member 41 abuts against the limiting surface 31 to limit the movement of the cleaning component 10 toward the surface to be cleaned 20. The limiting member 41 is moved in a direction parallel to the surface to be cleaned 20 (such as Figure 2 The device can be telescopically moved (as indicated by the arrow X in the middle).

[0044] During the process of assembling the cleaning assembly 10, the cleaning assembly 10 moves in a direction away from the surface to be cleaned 20. During the movement of the cleaning assembly 10, the stopper 41 retracts relative to the support member 11, and at this time, the orthographic projection of the stopper 41 on the surface to be cleaned 20 does not overlap with the orthographic projection of the stopper surface 31 on the surface to be cleaned 20, so that the stopper 41 can move to the side of the stopper surface 31 facing away from the surface to be cleaned 20. Afterwards, the stopper 41 extends relative to the support member 11, and at this time, the orthographic projection of the stopper 41 on the surface to be cleaned 20 overlaps with the orthographic projection of the stopper surface 31 on the surface to be cleaned 20, and the stopper 41 abuts against the stopper surface 31 at least under the action of the gravity of the cleaning assembly 10 as a whole, so as to limit the movement of the cleaning assembly 10 toward the surface to be cleaned 20, that is, to limit the separation of the cleaning assembly 10 from the device body, and the assembly operation of the cleaning assembly 10 is completed. During the process of disassembling the cleaning component 10, the limiting member 41 retracts relative to the supporting member 11, so that the orthographic projection of the limiting member 41 on the surface to be cleaned 20 and the orthographic projection of the limiting surface 31 on the surface to be cleaned 20 do not overlap, so as to allow the cleaning component 10 to move toward the surface to be cleaned 20, and then the cleaning component 10 is disassembled from the device body.

[0045] Of course, in other embodiments of the present application, the first limiting structure may be the limiting member 41, and the second limiting structure may be the limiting surface 31, that is, the limiting member 41 may be retractably arranged on the device body, and the limiting surface 31 may be arranged on the support member 11, and the limiting surface 31 may face the surface to be cleaned 20. The limiting surface 31 abuts against the limiting member 41 at least under the gravity of the cleaning assembly 10 as a whole, so as to limit the movement of the cleaning assembly 10 toward the surface to be cleaned 20. The embodiment of the present application is described by taking the first limiting structure as the limiting surface 31 and the second limiting structure as the limiting member 41 as an example, which is only for the purpose of discussion and does not constitute a limitation.

[0046] Please also refer to Figure 3The supporting member 11 includes a transmission part 111, a connecting part 112 and a supporting part 113. The transmission part 111 is rotatably connected to the device body. The connecting part 112 is transmission-connected to the transmission part 111, and the limiting member 41 is telescopically arranged on the connecting part 112. The supporting part 113 is transmission-connected to the connecting part 112, and the cleaning member 12 is arranged on the supporting part 113.

[0047] Please also read Figure 4 and Figure 5 , Figure 4 is a structural schematic diagram of the first embodiment of the positioning member of the present application, Figure 5 It is a structural schematic diagram of an embodiment of an output sleeve of the present application.

[0048] In one embodiment, the positioning member 30 includes a positioning body 35, and the positioning body 35 is surrounded to form a positioning hole 32, wherein at least part of the hole wall of the positioning hole 32 is a limiting surface 31. The cleaning device also includes a driving assembly 50. The driving assembly 50 is arranged on the device body, and the driving assembly 50 is located on the side of the positioning member 30 facing away from the surface to be cleaned 20. The supporting member 11 of the cleaning assembly 10 passes through the positioning hole 32 and is transmission-connected with the driving assembly 50, wherein the supporting member 11 is disposed in the positioning hole 32 and is also transmission-connected with the driving assembly 50. The driving assembly 50 is used to drive the supporting member 11 to rotate, and then drive the cleaning member 12 to rotate synchronously to clean the surface to be cleaned 20.

[0049] Specifically, the driving assembly 50 includes a power member (not shown) and an output sleeve 52. The power member is arranged on the main body of the device. The output sleeve 52 is connected to the power member in a transmission manner. The output sleeve 52 has a transmission cavity 53 inside, and the transmission part 111 of the support member 11 is embedded in the transmission cavity 53, so that the transmission part 111 is connected to the output sleeve 52 in a transmission manner. The power member drives the transmission part 111 to rotate through the output sleeve 52, that is, drives the support member 11 to rotate. The power member can be a power element such as a motor.

[0050] During the process of assembling the cleaning assembly 10, the support member 11 moves from the side of the positioning member 30 away from the driving assembly 50 toward the positioning member 30, so that the support member 11 passes through the positioning hole 32 and is transmission-connected with the driving assembly 50. Specifically, the transmission portion 111 of the support member 11 passes through the positioning hole 32 and is embedded in the transmission cavity 53 of the output sleeve 52; the connecting portion 112 enters the positioning hole 32 as the cleaning assembly 10 moves, so that the limiting member 41 provided on the connecting portion 112 can cooperate with the limiting surface 31 to limit the movement of the cleaning assembly 10 toward the surface 20 to be cleaned.

[0051] It should be noted that the inner wall surface of the output sleeve 52 facing the transmission cavity 53 is composed of a plurality of prismatic surfaces. Correspondingly, the outer peripheral surface of the transmission part 111 is composed of a corresponding number of prismatic surfaces. For example, the inner wall surface of the output sleeve 52 has six prismatic surfaces, and the overall shape of the transmission part 111 is a hexagonal prism, that is, the outer peripheral surface of the transmission part 111 also has six prismatic surfaces. After the transmission part 111 is embedded in the transmission cavity 53 of the output sleeve 52, the prismatic surfaces inside the output sleeve 52 and the prismatic surfaces on the periphery of the transmission part 111 are mutually limited and matched, so that the transmission part 111 is connected to the output sleeve 52 in transmission, and the transmission mode is reliable in force. In addition, the prismatic surfaces inside the output sleeve 52 and the prismatic surfaces on the periphery of the transmission part 111 can also guide the output sleeve 52 to dock with the transmission part 111, which can further facilitate the assembly of the cleaning component 10. Of course, in other embodiments of the present application, the transmission part 111 and the output sleeve 52 may also be connected to each other through other limiting matching structures, which is not limited here.

[0052] Please also read Figure 6 , Figure 6 yes Figure 4 The cross-sectional structure diagram of the positioning member in the BB direction is shown.

[0053] In one embodiment, the positioning hole 32 includes a first hole section 321 and a second hole section 322 that are connected to each other, and the first hole section 321 is located on the side of the second hole section 322 facing the surface to be cleaned 20. The cross-sectional area of ​​the first hole section 321 perpendicular to the rotation axis is smaller than the cross-sectional area of ​​the second hole section 322 perpendicular to the rotation axis, so that the limiting surface 31 is formed on the hole wall of the second hole section 322.

[0054] Specifically, during the process of assembling the cleaning assembly 10, the cleaning assembly 10 moves in a direction away from the surface to be cleaned 20, and the limiting member 41 retracts relative to the supporting member 11, so that the limiting member 41 can pass through the first hole section 321 and move to the side of the limiting surface 31 facing away from the surface to be cleaned 20. The limiting member 41 moves to the second hole section 322, and the limiting member 41 extends relative to the supporting member 11. The limiting member 41 abuts against the limiting surface 31 at least under the action of the gravity exerted on the cleaning assembly 10 as a whole, so as to limit the movement of the cleaning assembly 10 toward the surface to be cleaned 20. During the process of disassembling the cleaning assembly 10, the limiting member 41 retracts relative to the supporting member 11, so as to allow the limiting member 41 to pass through the second hole section 322 and the first hole section 321 in sequence and escape from the positioning hole 32, that is, to allow the cleaning assembly 10 to move toward the surface to be cleaned 20.

[0055] Furthermore, the positioning member 30 also has a guide surface 34. The guide surface 34 is closer to the surface to be cleaned 20 relative to the limiting surface 31. The guide surface 34 is arranged obliquely relative to the rotation axis, and the guide surface 34 also faces the rotation axis, and the guide surface 34 is used to guide the limiting member 41 to retract relative to the support member 11. In this way, during the process of assembling the cleaning component 10, the cleaning component 10 moves in a direction away from the surface to be cleaned 20, and the guide surface 34 guides the limiting member 41 to retract relative to the support member 11, so that the limiting member 41 can pass through the first hole section 321 and move to the side of the limiting surface 31 facing away from the surface to be cleaned 20.

[0056] Furthermore, the positioning hole 32 further includes a third hole section 323. The third hole section 323 is located on the side of the first hole section 321 facing the surface to be cleaned 20, and the first hole section 321 and the third hole section 323 are connected to each other. The cross-sectional area of ​​the first hole section 321 perpendicular to the rotation axis is smaller than the cross-sectional area of ​​the third hole section 323 perpendicular to the rotation axis, so that the guide surface 34 is formed on the hole wall of the third hole section 323.

[0057] It should be noted that, in the embodiment of the present application, the limiting surface 31 is preferably arranged to be inclined relative to the rotation axis. During the process of disassembling the cleaning assembly 10, the limiting surface 31 can guide the limiting member 41 to retract relative to the support member 11, so as to allow the limiting member 41 to escape from the positioning hole 32. The angle α between the limiting surface 31 and the rotation axis is greater than the angle β between the guide surface 34 and the rotation axis. Figure 6 As shown. In this way, the angle α between the limiting surface 31 and the rotation axis is large, which means that the limiting member 41 can reliably abut against the limiting surface 31, which can reduce the risk of the cleaning component 10 falling due to abnormal conditions such as vibration causing the limiting member 41 to be guided and retracted by the limiting surface 31; and the angle β between the guide surface 34 and the rotation axis is small, which makes it easier for the guide surface 34 to guide the limiting member 41 to retract, which means that the user only needs to apply a small force to the cleaning component 10 to drive the limiting member 41 to retract, further facilitating the user to assemble the cleaning component 10.

[0058] Regarding the above-mentioned angle α between the limiting surface 31 and the rotation axis being greater than the angle β between the guiding surface 34 and the rotation axis, it should be understood that the angle between the tangent at least part of the limiting surface 31 and the rotation axis is greater than the angle between the tangent at at least part of the guiding surface 34 and the rotation axis.

[0059] In one embodiment, the cleaning device further includes an elastic member 42. The limiting member 41 is retractably disposed on the supporting member 11 through the elastic member 42. When the limiting member 41 moves to the side of the limiting surface 31 facing away from the surface to be cleaned 20, the elastic member 42 drives the limiting member 41 to extend relative to the supporting member 11.

[0060] Specifically, during the process of assembling the cleaning assembly 10, the cleaning assembly 10 moves in a direction away from the surface to be cleaned 20, and the guide surface 34 guides the limiting member 41 to retract relative to the supporting member 11. At this time, the limiting member 41 causes the elastic member 42 to undergo elastic deformation, and the limiting member 41 can pass through the first hole section 321 and move to the side of the limiting surface 31 that is away from the surface to be cleaned 20. The limiting member 41 moves to the second hole section 322, and the elastic member 42 drives the limiting member 41 to extend relative to the supporting member 11 in response to its own elastic restoring force. The limiting member 41 abuts against the limiting surface 31 at least under the action of the gravity exerted on the cleaning assembly 10 as a whole, so as to limit the movement of the cleaning assembly 10 toward the surface to be cleaned 20. During the process of disassembling the cleaning assembly 10, the limiting surface 31 guides the limiting member 41 to retract relative to the supporting member 11, so as to allow the limiting member 41 to pass through the second hole section 322 and the first hole section 321 in sequence and escape from the positioning hole 32. After the limiting member 41 passes through the first hole section 321 , the elastic member 42 drives the limiting member 41 to gradually extend relative to the supporting member 11 in response to its own elastic restoring force.

[0061] Optionally, the elastic member 42 may be an elastic element such as a compression spring. When the limiting member 41 retracts relative to the supporting member 11, the limiting member 41 squeezes the elastic member 42 and causes the elastic member 42 to undergo elastic deformation. The service life of the elastic member 42 is much longer than the service life of the screws used in the screw locking method in the prior art. Of course, in other embodiments of the present application, the elastic member 42 may also be an elastic element such as a tension spring, and the limiting member 41 causes the elastic member 42 to undergo elastic deformation by stretching the elastic member 42. At this time, the setting position of the elastic member 42 needs to be adaptively adjusted. The embodiment of the present application is described by taking the elastic member 42 as a compression spring as an example, which is only for the purpose of discussion and does not constitute a limitation.

[0062] Furthermore, the number of the limiting members 41 may be at least two. The limiting members 41 are evenly spaced along the circumference of the rotation axis, and the elastic member 42 is used to drive the limiting members 41 to move in a direction away from the rotation axis, so that the limiting members 41 extend relative to the support member 11. In this way, the present embodiment can reduce the risk of the cleaning assembly 10 falling due to abnormal conditions such as vibration by cooperating with the at least two limiting members 41 and the limiting surface 31.

[0063] For example, Figure 2 As shown, for the example in which the elastic member 42 is a compression spring, the number of the limiting members 41 is two. A limiting member 41 is provided at opposite ends of the elastic member 42. The interior of the support member 11 has a cavity. The elastic member 42 is accommodated in the cavity. A through hole structure is provided at opposite sides of the connecting portion 112 of the support member 11. A portion of each limiting member 41 is accommodated in the cavity to be connected to the elastic member 42, and each limiting member 41 extends or retracts relative to the support member 11 through the corresponding hole structure.

[0064] The above-mentioned limiting surface 31 and guide surface 34 are both arranged around the outer circumference of the rotation axis. During the process of assembling the cleaning assembly 10, the cleaning assembly 10 moves in a direction away from the surface to be cleaned 20, and the guide surface 34 guides the two limiting members 41 to retract relative to the support member 11. At this time, the two limiting members 41 cooperate to squeeze the elastic member 42, and the two limiting members 41 pass through the first hole section 321 and move to the side of the limiting surface 31 that is away from the surface to be cleaned 20. When the two limiting members 41 move to the second hole section 322, the elastic member 42 drives the two limiting members 41 to extend relative to the support member 11 in response to its own elastic restoring force. The two limiting members 41 abut against the limiting surface 31 at least under the action of the gravity of the cleaning assembly 10 as a whole, so as to limit the cleaning assembly 10 from moving toward the surface to be cleaned 20. During the process of disassembling the cleaning assembly 10, the limiting surface 31 guides the two limiting members 41 to retract relative to the supporting member 11. At this time, the two limiting members 41 cooperate to squeeze the elastic member 42 and allow the two limiting members 41 to pass through the second hole section 322 and the first hole section 321 in sequence and escape from the positioning hole 32. After the two limiting members 41 pass through the first hole section 321, the elastic member 42 drives the two limiting members 41 to gradually extend relative to the supporting member 11 in response to its own elastic restoring force.

[0065] It should be noted that the angle between the limit surface 31 and the rotation axis, the angle between the guide surface 34 and the rotation axis, and the elastic modulus of the elastic member 42 affect the force required for the user to assemble or disassemble the cleaning assembly 10. The embodiment of the present application reasonably sets the angle between the limit surface 31 and the rotation axis, the angle between the guide surface 34 and the rotation axis, and the elastic modulus of the elastic member 42, so that the user can easily assemble and disassemble the cleaning assembly 10.

[0066] In one embodiment, when the driving assembly 50 drives the support member 11 to rotate, the limiting member 41 rotates synchronously with the support member 11. Since the limiting member 41 is in contact with the limiting surface 31 of the positioning member 30 for a long time, the positioning member 30 is preferably rotatably arranged on the device body in this embodiment to reduce the relative movement between the limiting member 41 and the positioning member 30, thereby reducing the wear degree of the limiting member 41 and the positioning member 30.

[0067] In this embodiment, it is further preferred that the limiting member 41 and the positioning member 30 rotate synchronously, so that there is no relative displacement between the limiting member 41 and the positioning member 30, thereby minimizing the degree of wear of the limiting member 41 and the positioning member 30. For details, please refer to Figure 7The positioning member 30 also has a limiting hole 33. The limiting hole 33 is away from the to-be-cleaned surface 20 relative to the first hole section 321, and the limiting hole 33 is connected to the second hole section 322. When the limiting member 41 is located in the second hole section 322, the limiting member 41 can extend and embed into the limiting hole 33 to drive the positioning member 30 to rotate synchronously. The limiting hole 33 is provided in the positioning body 35, and the limiting hole 33 is located at the outer periphery of the second hole section 322. The limiting hole 33 can be a blind hole or a through hole that penetrates the positioning body 35. Figure 7 The limiting hole 33 is exemplarily shown to be a through hole penetrating the positioning body 35 .

[0068] It should be noted that when the limiting member 41 is located in the second hole section 322, if the limiting member 41 is not aligned with the limiting hole 33, the support member 11 and the limiting member 41 thereon can rotate in the positioning hole 32, that is, the limiting member 41 is allowed to extend and embed into the limiting hole 33 as the support member 11 rotates, so as to drive the positioning member 30 to rotate synchronously. When the limiting member 41 is aligned with the limiting hole 33 as the support member 11 rotates, the limiting member 41 further extends relative to the support member 11 and embeds into the limiting hole 33. In other words, this embodiment allows the cleaning component 10 to be clamped at any angle, that is, the support member 11 of the cleaning component 10 can pass through the positioning hole 32 on the positioning member 30 at any angle, and the limiting member 41 can be embedded in the limiting hole 33 and installed in place by appropriately rotating the support member 11.

[0069] Furthermore, in the case where the positioning member 30 is rotatably disposed on the device body, the cleaning device further includes a rotating bearing (not shown), and the positioning member 30 is rotatably disposed on the device body via the rotating bearing. Alternatively, the output sleeve 52 of the driving assembly 50 and the positioning member 30 are an integral structure. In the process of the power member driving the output sleeve 52 to rotate, the positioning member 30 rotates synchronously with the output sleeve 52. At this time, since the output sleeve 52 and the support member 11 maintain synchronous rotation, that is, the support member 11 and the positioning member 30 also maintain synchronous rotation, the positioning member 30 can eliminate the limiting hole 33, thereby simplifying the structure of the positioning member 30 and ensuring the structural strength of the positioning member 30.

[0070] In one embodiment, the limiting surface 31 is arranged around the outer periphery of the rotation axis, so that the limiting member 41 can move along the limiting surface 31 with the rotation of the supporting member 11. In other words, this embodiment allows the cleaning component 10 to be clamped at any angle, that is, the supporting member 11 of the cleaning component 10 can pass through the positioning hole 32 on the positioning member 30 at any angle, and the limiting member 41 on the supporting member 11 can abut against the limiting surface 31, and the limiting surface 31 supports the design that the limiting member 41 rotates with the supporting member 11.

[0071] Furthermore, the positioning member 30 can be fixed to the device body. In the above manner, the present embodiment omits the design of the rotational connection between the positioning member 30 and the device body in the above embodiment, which is conducive to simplifying the structure related to the positioning member 30, thereby simplifying the structure of the cleaning device and reducing the manufacturing cost.

[0072] The technical solution provided in the embodiment of the present application is described below in conjunction with specific application scenarios.

[0073] Application scenario 1:

[0074] The cleaning device is specifically a cleaning robot. The cleaning device includes a device body. The cleaning device also includes a cleaning assembly 10. The cleaning assembly 10 includes a support 11 and a cleaning member 12, the support 11 is rotatably connected to the device body, the cleaning member 12 is arranged on the support 11 and can rotate with the support 11, and the cleaning member 12 is used to clean the surface to be cleaned 20. The cleaning device also includes a first limiting structure, and the first limiting structure is connected to the device body. The cleaning device also includes a second limiting structure, and the second limiting structure is connected to the support 11. Among them, one of the first limiting structure and the second limiting structure is a limiting surface 31, and the limiting surface 31 is inclined or parallel to the surface to be cleaned 20, and the other is a retractable limiting member 41; by retracting the limiting member 41, the second limiting structure can be moved to the side of the first limiting structure that is opposite to the surface to be cleaned 20, and by extending the limiting member 41, the limiting member 41 and the limiting surface 31 can cooperate to limit the movement of the cleaning assembly 10 toward the surface to be cleaned 20.

[0075] When the user needs to assemble the cleaning assembly 10 to the main body of the cleaning device, the user needs to place the cleaning assembly 10 on the side (i.e., the bottom) of the main body of the device facing the surface 20 to be cleaned, and the user drives the cleaning assembly 10 to move in a direction away from the surface 20 to be cleaned, so that the cleaning assembly 10 is assembled to the main body of the device. Specifically, during the process of assembling the cleaning assembly 10, the cleaning assembly 10 moves in a direction away from the surface 20 to be cleaned, and the guide surface 34 of the positioning member 30 guides the two limiting members 41 on the support member 11 to retract relative to the support member 11. At this time, the two limiting members 41 cooperate to squeeze the elastic member 42, and the two limiting members 41 pass through the first hole section 321 of the positioning hole 32 of the positioning member 30 and move to the side of the limiting surface 31 of the positioning member 30 facing away from the surface 20 to be cleaned. When the two limiting members 41 move to the second hole section 322, the elastic member 42 drives the two limiting members 41 to extend relative to the supporting member 11 in response to its own elastic restoring force. The two limiting members 41 abut against the limiting surface 31 at least under the action of the gravity exerted on the cleaning component 10 as a whole, so as to limit the movement of the cleaning component 10 toward the surface to be cleaned 20, thereby completing the assembly operation of the cleaning component 10.

[0076] When the user needs to remove the cleaning component 10 from the device body, the user drives the cleaning component 10 to move toward the surface to be cleaned 20, so that the cleaning component 10 is separated from the device body. Specifically, in the process of removing the cleaning component 10, the limiting surface 31 guides the two limiting members 41 to retract relative to the support member 11. At this time, the two limiting members 41 cooperate to squeeze the elastic member 42, and allow the two limiting members 41 to pass through the second hole section 322 and the first hole section 321 in turn and escape from the positioning hole 32. After the two limiting members 41 pass through the first hole section 321, the elastic member 42 drives the two limiting members 41 to gradually extend relative to the support member 11 in response to its own elastic restoring force. At this point, the disassembly operation of the cleaning component 10 is completed.
