Description

Technical Field

[0001] This application relates to the field of cleaning technology, and particularly to a cleaning device. Background Art

[0002] Cleaning devices can assist users in cleaning during household life. Some existing cleaning devices, such as floor mopping machines and sweeping robots, generally drive a cleaning belt to mop the surface to be cleaned by rolling a roller. The cleaning belt cooperates with an inclined plane to convey garbage, and the inclined plane is provided to support the cleaning belt, reducing the acting force between the cleaning device and the surface to be cleaned, and thus resulting in a poor cleaning effect between the cleaning device and the surface to be cleaned. Summary of the Utility Model

[0003] This application provides a cleaning device. The cleaning device includes a main frame and a cleaning module. A wheel body is provided on the main frame, and the wheel body forms a support plane for contacting the surface to be cleaned. The cleaning module is provided on the main frame. The main frame is provided with a conveying inclined plane. The cleaning module includes a first roller, a second roller, a connecting rod assembly, and a cleaning belt. One end of the first roller and the connecting rod assembly is rotatably supported on the main frame. The first roller can rotate around a first axis, and the connecting rod assembly can swing around a second axis parallel to the first axis. The second roller is supported at the other end of the connecting rod assembly and can rotate around a third axis parallel to the first axis. The cleaning belt is annularly arranged around the outer periphery of the first roller and the second roller. The cleaning belt abuts against the front side of the conveying inclined plane for conveying garbage from the lower end of the conveying inclined plane to the upper end of the conveying inclined plane. The second roller is adjacent to the lower end of the conveying inclined plane. In a reference section perpendicular to the support plane and the first axis, the conveying inclined plane includes a first conveying section adjacent to the lower end of the conveying inclined plane. The first conveying section is disposed opposite to the second roller and is recessed away from the second roller.

[0004] The beneficial effect brought by this application is that by recessing the first conveying section, the second roller can extend into the recessed area, reducing the supporting acting force of the first conveying section on the cleaning module, increasing the acting force between the cleaning module and the surface to be cleaned, and thus improving the cleaning effect between the cleaning device and the surface to be cleaned.

[0025] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0026] The present application describes a cleaning system. The cleaning system can be used in daily cleaning work and can clean the surface to be cleaned. For example, it can clean the garbage that affects the floor cleaning, such as particulate matter, linear matter, debris, strip-shaped matter, sheet-shaped matter, liquid, stains, etc. on the surface to be cleaned. Specifically, based on the design requirements of the cleaning system, the cleaning system can clean the garbage corresponding to the design requirements.

[0027] The surface to be cleaned can exist on the ground, stairs, floor, tabletop, etc., on various structures where garbage may exist and may need to be cleaned, which will not be elaborated.

The user can control the cleaning main body 103 through the handle 104 for cleaning and / or moving. In some embodiments, the cleaning main body 103 and the handle 104 can cooperate to accommodate liquids, batteries, processors, control panels, and / or control buttons for cleaning, etc.

[0030] In Figure 2 , the user can hold the handle 104 and control the cleaning main body 103 to move in the front-back direction, such as moving forward, moving backward, or moving back and forth, and of course, can also control the cleaning main body 103 to turn.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0032] In some embodiments, the handle 104 may be omitted, and the cleaning body 103 may be cleaned and / or moved under intelligent control.

[0033] Please refer to Figure 3 and Figure 4 , Figure 3 which is Figure 2 a schematic structural view of the cleaning body 103 in some of the illustrated embodiments, Figure 4 and Figure 3 a partial exploded view of the cleaning body 103 in some of the illustrated embodiments.

The wheel body 13 can enable the base 11 to move on the surface to be cleaned.

[0035] It should also be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element present at the same time. When an element is referred to as "connected" to another element, it can be directly connected to the other element or there may be an intermediate element present at the same time.

[0036] Please refer to Figure 3 , Figure 4 and Figure 5 , Figure 5 which is Figure 4 a schematic structural view of the cooperation between the base 11 and the scraper 30 in some of the illustrated embodiments. The base 11 can be a shell structure or a frame structure. In some embodiments, the base 11 may include a bottom wall 111, a top wall 112, a first side wall 113, and a second side wall 114. The bottom wall 111 and the top wall 112 are oppositely arranged. The first side wall 113 and the second side wall 114 are oppositely arranged. The bottom wall 111, the first side wall 113, the top wall 112, and the second side wall 114 may be sequentially connected. In some embodiments, the base 11 is provided with an installation space 1001 to carry and install the cleaning module 20, the scraper 30, and the storage box 40. In some embodiments, the installation space 1001 may be at least formed by enclosing the bottom wall 111, the top wall 112, the first side wall 113, and the second side wall 114.

[0037] Of course, in some embodiments, the base 11 may further include other side walls, which will not be elaborated herein.

[0038] In some embodiments, Figure 3 a card slot 1111 is provided on the bottom wall 111 of the base 11 for positioning and limiting cooperation with the base station 102, so as to improve the stability of the cleaning body 103 when placed on the base station 102. In some scenarios, the card slot 1111 may also be provided on other structures in the base 11, for example, it may be provided on the first side wall 113 and the second side wall 114. Of course, the card slot 1111 may also be provided on other structures in the cleaning body 103 according to design requirements, which will not be elaborated herein.

[0039] In some embodiments, Figure 3 a first electrical connection terminal 1131 is provided on the first side wall 113 of the base 11, so that the cleaning device 101, such as the cleaning body 103, is electrically connected to the base station 102 or other devices through the first electrical connection terminal 1131. Furthermore, charging operation of the cleaning device 101 can be realized, control of the base station 102 or other devices by the cleaning device 101 can be realized, interaction between the cleaning device 101 and the base station 102 or other devices can also be realized, and system upgrade or maintenance of the cleaning device 101, such as the cleaning body 103, can also be realized. Of course, the first electrical connection terminal 1131 can also be selectively provided on other parts of the cleaning device 101, such as the cleaning body 103, according to the needs of those skilled in the art.

[0040] It can be understood that the structural setting of the base 11 is not limited to the above embodiments, and the structure can also be set in other ways, which will not be elaborated herein.

[0041] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , Figure 6 which are Figure 3 a cross-sectional schematic view of the cleaning body 103 at the line VI-VI in the embodiment shown, Figure 7 and Figure 6 a structural schematic view of the cleaning body 103 on the surface to be cleaned in the embodiment shown. The base 11 is provided with a conveying part 115 inside the installation space 1001. The conveying part 115 can cooperate with the cleaning module 20 to pick up and / or convey garbage.

[0042] In some embodiments, the conveying part 115 can scrape the surface to be cleaned to gather garbage. In some embodiments, the conveying part 115 can cooperate with the cleaning module 20 to pick up the garbage on the surface to be cleaned. In some embodiments, the conveying part 115 can cooperate with the cleaning module 20 to convey the garbage to the storage box 40 for conveying.

[0043] The conveying part 115 can divide the installation space 1001 into a containing space 1002 and a storage space 1003. The containing space 1002 is located on the front side of the conveying part 115 and is used to contain the cleaning module 20. The storage space 1003 is located on the rear side of the conveying part 115 and is used to contain the storage box 40. The conveying part 115 can cooperate with the cleaning module 20 to convey the garbage from the containing space 1002 to the storage space 1003.

[0044] A conveying inclined plane 1151 is arranged on the front side of the conveying part 115. The conveying inclined plane 1151 can cooperate with the cleaning module 20 so that the garbage can be conveyed from the lower end of the conveying inclined plane 1151 to the upper end of the conveying inclined plane 1151.

[0045] The upper end of the conveying inclined plane 1151 is more backward than the lower end of the conveying inclined plane 1151, while the lower end of the conveying inclined plane 1151 is more forward than the upper end of the conveying inclined plane 1151. The combination of the slope of the conveying inclined plane 1151 and the parameters of the upper end of the conveying inclined plane 1151 can ensure the garbage conveying height while meeting the garbage conveying capacity of the cleaning main body 103, so that the storage box 40 has a deeper garbage cavity.

[0046] A dropping port 1004 is arranged on the base 11. The dropping port 1004 is arranged near the upper end of the conveying inclined plane 1151 and can communicate the containing space 1002 and the storage space 1003. Thus, when the garbage is located at the upper end of the conveying inclined plane 1151, it can fall into the storage box 40 in the storage space 1003 from the dropping port 1004.

[0047] Please refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7 ., an introducing part 116 can be arranged at the bottom of the conveying part 115 on the base 11. The introducing part 116 is located on one side of the conveying inclined plane 1151 extending towards the surface to be cleaned. In some embodiments, the introducing part 116 can contact the surface to be cleaned or can have a small distance from the surface to be cleaned.

[0048] The introducing part 116 can be used to perform at least one of the following functions: scraping the garbage on the surface to be cleaned, cooperating with the cleaning module 20 to pick up the garbage on the surface to be cleaned, and cooperating with the cleaning module 20 to convey the garbage to the conveying inclined plane 1151.

[0049] The introducing part 116 is arranged near the lower end of the conveying inclined plane 1151, and the surface of the introducing part 116 cooperating with the cleaning module 20 can be in transitional connection with the conveying inclined plane 1151. The introducing part 116 can cooperate with the cleaning module 20 to clean the garbage on the surface to be cleaned and convey the garbage to the conveying inclined plane 1151.

[0050] When the cleaning body 103 cleans the surface to be cleaned, the introduction part 116 scrapes the garbage on the surface to be cleaned or can gather the garbage together. The introduction part 116 cooperates with the cleaning module 20 to pick up the garbage on the surface to be cleaned and can convey the garbage to the transfer inclined plane 1151.

[0051] In some embodiments, when at least part of the functions of the introduction part 116 can be achieved by the transfer part 115, the introduction part 116 can be omitted.

[0052] Please refer to Figure 4 , Figure 6 and Figure 7 , the flip cover 12 can be used to perform maintenance, assembly and cleaning of the cleaning body 103. The flip cover 12 can be connected to the base 11 at the front side of the base 11.

[0053] An assembly opening can be formed at the front side of the base 11, and the flip cover 12 can be covered at the assembly opening to cover the assembly opening. The assembly opening can communicate with the accommodation space 1002.

[0054] In some embodiments, the assembly opening can be formed at the front side of the base 11 when the bottom wall 111, the top wall 112, the first side wall 113 and the second side wall 114 enclose. In some embodiments, the assembly opening can be arranged on the top wall 112.

[0055] It can be understood that in this application, the descriptions involving "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" can explicitly or implicitly include at least one of such features.

[0056] In some embodiments, the flip cover 12 can be connected to at least one of the top wall 112, the first side wall 113 and the second side wall 114. In some embodiments, the flip cover 12 can be a part of the base 11.

[0057] Please refer to Figure 3 , the wheel body 13 can be arranged on the base 11, such as on the bottom wall 111. The wheel body 13 can roll, and thus the movement of the cleaning body 103 can be realized. In some embodiments, a motor can be arranged inside the cleaning body 103 to drive the wheel body 13 to rotate. In some embodiments, the wheel body 13 can also be arranged on other structures in the base 11, such as on the first side wall 113 and the second side wall 114, which will not be elaborated.

[0058] The arrangement of the wheel body 13 can form a support plane PL (as Figure 6 shown) for contacting the surface to be cleaned.

[0059] In some embodiments, the wheel body 13 may include a front wheel body 131 and a rear wheel body 132. The front wheel body 131 is further forward than the rear wheel body 132, and the rear wheel body 132 is further backward than the front wheel body 131. In some embodiments, the slot 1111 may be located between the front wheel body 131 and the rear wheel body 132. In some embodiments, the introduction portion 116 may be further forward than the front wheel body 131. In some embodiments, the forward direction may be the traveling direction.

[0060] See also Figure 3 and Figure 4 The cleaning module 20 can be mounted on the base 11 and can be against the front side of the introduction portion 116 and / or the conveying slope 1151. The cleaning module 20 can extend from the accommodating space 1002 from the assembly port to contact the surface to be cleaned to achieve garbage cleaning.

[0061] See also Figure 4 , Figure 6 and Figure 7 The cleaning module 20 may include a first roller 21, a second roller 22, a connecting rod assembly 23 and a cleaning belt 24. One end of the first roller 21 and the connecting rod assembly 23 are rotatably supported on the base 11, and the second roller 22 is supported on the other end of the connecting rod assembly 23. The cleaning belt 24 is annularly arranged around the periphery of the first roller 21 and the second roller 22. When the first roller 21 and / or the second roller 22 rotates, the cleaning belt 24 is driven to rotate.

[0062] The first roller 21 can be rotatably connected to the base 11, for example, rotatably connected to the first side wall 113 and the second side wall 114. Of course, under the structural requirements of the base 11, the first roller 21 can also be rotatably connected to other parts of the base 11.

[0063] In some embodiments, the first roller 21 may be disposed adjacent to the upper end of the conveying slope 1151. In some embodiments, the first roller 21 may be located above the drop opening 1004.

[0064] The connecting rod assembly 23 can be rotatably connected to the base 11. For example, it can be rotatably connected to the first side wall 113 and the second side wall 114. Of course, under the structural requirements of the base 11, the connecting rod assembly 23 can also be rotatably connected to other parts of the base 11.

[0065] It can be understood that when the connecting rod assembly 23 is rotatably connected to the base 11, the connecting rod assembly 23 can swing when rotating.

[0066] In some embodiments, a motor may be provided in the connecting rod assembly 23, and the motor may be in transmission connection with the first roller 21 and / or the second roller 22, so as to drive the first roller 21 and / or the second roller 22 to rotate, thereby driving the cleaning belt 24 to rotate. In some embodiments, the motor may be provided on the base 11.

[0067] In some embodiments, the connecting rod assembly 23 may not be rotatably connected to the base 11, but rotatably connected to the first roller 21, so as to be indirectly rotatably connected to the base 11 through the first roller 21. In some embodiments, the first roller 21 may not be rotatably connected to the base 11, but rotatably connected to the connecting rod assembly 23, so as to be indirectly rotatably connected to the base 11 through the connecting rod assembly 23.

[0068] In some embodiments, both the first roller 21 and the connecting rod assembly 23 can rotate about a first axis. In some embodiments, the first roller 21 can rotate about a first axis, and the connecting rod assembly 23 can rotate about a second axis. The second axis is parallel to the first axis.

[0069] In some embodiments, the second axis may be coaxially arranged with the first axis or may not be coaxially arranged. That is, the second axis and the first axis are the same line.

[0070] The second roller 22 can be rotatably connected to the connecting rod assembly 23 and can rotate about a third axis. In some embodiments, the third axis is arranged parallel to the first axis. In some embodiments, the second roller 22 is disposed adjacent to the lower end of the transfer inclined surface 1151.

[0071] The cleaning belt 24 can be abutted against the front side of the guiding portion 116 and / or the transfer inclined surface 1151, or can be abutted against the surface to be cleaned.

[0072] When the cleaning belt 24 rotates, it can clean the garbage on the surface to be cleaned, and can cooperate with the guiding portion 116 to clean and pick up the garbage on the surface to be cleaned, and can convey the garbage to the transfer inclined surface 1151. The cleaning belt 24 cooperates with the transfer inclined surface 1151 to convey the garbage from the lower end of the transfer inclined surface 1151 to the upper end of the transfer inclined surface 1151, and further convey it to the storage box 40.

[0073] The cleaning belt 24 can be pressed against the surface to be cleaned by the second roller 22 to increase the pressure between the cleaning belt 24 and the surface to be cleaned and improve the cleaning effect. In some embodiments, during the process of placing the cleaning main body 103 on the surface to be cleaned, the connecting rod assembly 23 can swing to support the cleaning module 20 by the surface to be cleaned as much as possible, so that the second roller 22 presses the cleaning belt 24 against the surface to be cleaned. In some embodiments, when the cleaning main body 103 cleans the garbage on the surface to be cleaned, it will contact the garbage and can be supported by the garbage, and then the connecting rod assembly 23 can swing to lift the second roller 22 and the cleaning belt 24 to cross the garbage on the surface to be cleaned. The cleaning belt 24 can be made of a water-absorbing material. Of course, in order to improve the cleaning effect, the cleaning belt 24 can also be provided with a multi-layer structure.

[0074] Please refer to Figure 8 , Figure 8 For Figure 6Schematic diagram of the structure of the middle cleaning module 20 cooperating with the conveying part 115 and the introducing part 116. The cleaning belt 24 may include a base layer 241 wound around the outer peripheries of the first roller 21 and the second roller 22, and a fluff layer 242 provided on the outer peripheral surface of the base layer 241. The base layer 241 can serve as the main body of the cleaning belt 24 to realize the arrangement of the cleaning belt 24 on the first roller 21 and the second roller 22, and is used for arranging the fluff layer 242. The fluff layer 242 serves as the cleaning layer of the cleaning belt 24. When the cleaning belt 24 is stressed, an interference amount will be generated on the fluff layer 242, causing the fluff layer 242 to be compressed. The arrangement of the fluff layer 242 can improve the cleaning ability of the cleaning belt 24.

[0075] It should be noted that regardless of the state of the cleaning belt 24, without being worn, the fluff length of the fluff layer 242 remains unchanged, and the fluff length of the fluff layer 242 mentioned in this article refers to the length of the fluff when it is not worn and in a natural stretched state.

[0076] And the cleaning belt 24 described in this application may be in three states:

[0077] The first state is that the cleaning belt 24 is in the factory state, the cleaning belt 24 is not wetted by liquid and is in a dry state. At this time, the fluff layer 242 is relatively fluffy, and when the fluff layer 242 is pressed against the ground to be cleaned, there will be a large deformation.

[0078] The second state is that after the cleaning belt 24 has run for a period of time after leaving the factory state, and the cleaning belt 24 is not wetted by liquid and is in a dry state. For example, running in a fixed direction (such as Figure 6 the counterclockwise direction or the clockwise direction in

[0079] for at least 5 hours), the fluff layer 242 will be relatively compacted. When the fluff layer 242 is pressed against the ground to be cleaned, the degree of deformation is relatively reduced.

[0080] The third state is that after the cleaning belt 24 has run for at least 5 hours after leaving the factory state, the cleaning belt 24 is wetted with liquid. When the cleaning belt 24 is pressed against the ground to be cleaned, the degree of deformation will be further reduced.

[0080] Furthermore, in the description of this application, the interference amount of any component on the fluff layer 242 refers to the difference obtained by subtracting the distance between the component and the base layer 241 from the fluff length of the fluff layer 242. In addition, if the distance between the component and the base layer 241 is variable, the minimum distance between the component and the base layer 241 can be used to calculate the interference amount on the fluff layer 242.

[0081] In the above second state, when the cleaning belt 24 is naturally wound around the first roller 32 and the second roller 33 and is not subjected to force (such as the force between the surface to be cleaned, the conveying part 115 or the guiding part 116), it can be considered to be in a natural state. Furthermore, both the cleaning belt 24 and the fluff layer 242 can have a natural thickness (which can also be called "the thickness in the natural state").

[0082] Please refer to Figure 6 and Figure 7 , when the cleaning module 20 is not in contact with the surface to be cleaned, the link assembly 23 can swing, enabling a part of the cleaning module 20, such as the cleaning belt 24, to be located below the support plane PL. At this time, based on the gravity of the cleaning module 20, the cleaning belt 24 can be pressed against the guiding part 116 and / or the conveying inclined plane 1151. Of course, at this time, part of the second roller 22 can also be located below the support plane PL, or the second roller 22 can be entirely located above the support plane PL.

[0083] Optionally, when the cleaning module 20 mentioned in this application is located below the support plane PL, it can be the lowest point of the cleaning module 20, that is, the lowest point of the cleaning belt 24 is located below the support plane PL, or it can be a part of the cleaning module 20, that is, a part of the cleaning belt 24 is located below the support plane PL, or it can be a part of the cleaning module 20, that is, a part of the cleaning belt 24 and the second roller 22 are located below the support plane PL. There is no limitation here.

[0084] When the cleaning module 20 is in contact with the surface to be cleaned, the cleaning module 20 can be supported by the surface to be cleaned and can be located on the support plane PL. Of course, due to the structural limitations of the surface to be cleaned, the cleaning module 20 will deviate from the support plane PL, but it can still be supported by the surface to be cleaned. At this time, based on the gravity of the cleaning module 20 being shared by the surface to be cleaned, when the cleaning belt 24 is pressed against the guiding part 116 and / or the conveying inclined plane 1151, compared with the situation where the cleaning module 20 is not in contact with the surface to be cleaned, the pressure of the cleaning belt 24 on the guiding part 116 and / or the conveying inclined plane 1151 decreases.

[0085] In addition, compared with the situation where the cleaning module 20 is in contact with the surface to be cleaned, when the cleaning module 20 is not in contact with the surface to be cleaned, it can better increase the interference amount between the cleaning belt 24 and the guiding part 116, and / or the interference amount between the cleaning belt 24 and the conveying inclined plane 1151.

[0086] Please refer to Figure 6 and Figure 7 , when the cleaning module 20 is not in contact with the surface to be cleaned, the second roller 22 and the cleaning belt 24 are in a suspended state without contacting the surface to be cleaned. Furthermore, the cleaning main body 103 can start the self-cleaning mode to clean the guiding part 116 and / or the conveying inclined plane 1151 through the cleaning belt 24.

[0087] It can be understood that the suspended state refers to the state in which the second roller 22 and the cleaning belt 24 do not contact structures other than the cleaning device 101 and are supported by the cleaning device 101, such as the introduction part 116 and / or the conveying inclined plane 1151. At this time, it can also be said that the cleaning module 20 is in a suspended state.

[0088] Optionally, in some scenarios, the cleaning module 20 is carried on the introduction part 116 and / or the conveying inclined plane 1151 under the action of gravity and is subjected to the pulling force of the main frame 10. The cleaning module 20, such as the cleaning belt 24, is arranged at an interval from the surface to be cleaned.

[0089] In some embodiments, in the self-cleaning mode, the second roller 22 can rotate in the first direction, thereby driving the cleaning belt 24 to rotate in the first direction. Furthermore, the cleaning belt 24 can clean the introduction part 116 and / or the conveying inclined plane 1151, and further clean the garbage remaining on the introduction part 116 and / or the conveying inclined plane 1151 and convey it to the storage box 40.

[0090] In some embodiments, the first direction can be Figure 6 the counterclockwise direction in

[0091] In some embodiments, in the self-cleaning mode, the second roller 22 can rotate in the second direction, thereby driving the cleaning belt 24 to rotate in the second direction. Furthermore, the cleaning belt 24 can clean the introduction part 116 and / or the conveying inclined plane 1151, and further clean the garbage remaining on the introduction part 116 and / or the conveying inclined plane 1151, and can be conveyed to the storage box 40 when the cleaning belt 24 rotates in the first direction.

[0092] In some embodiments, the second direction can be Figure 6 the clockwise direction in

[0093] In some embodiments, in the self-cleaning mode, the second roller 22 can rotate in the first direction or the second direction, thereby driving the cleaning belt 24 to rotate. Furthermore, the cleaning belt 24 can be cleaned by the scraper 30 to achieve the cleaning of the cleaning belt 24.

[0094] In some embodiments, in the self-cleaning mode, the second roller 22 can rotate in the first direction or the second direction, thereby driving the cleaning belt 24 to rotate. Furthermore, the cleaning belt 24 can be cleaned by the cleaning liquid, and the garbage on the introduction part 116 and / or the conveying inclined plane 1151 can also be cleaned by the cleaning liquid.

[0095] In some embodiments, the self-cleaning mode can include multiple stages, and different cleaning matters can be carried out in different stages. When starting the self-cleaning mode, at least one stage in the self-cleaning mode can be executed.

[0096] In some embodiments, in the first stage of the self-cleaning mode, the second roller 22 can rotate alternately in the first direction and the second direction opposite to the first direction, while driving the cleaning belt 24 to rotate, so as to clean the garbage remaining on the introduction part 116 and / or the conveying inclined plane 1151, which can improve the effect of removing the difficult-to-remove garbage. In some embodiments, in the first stage, the displacement of the cleaning belt 24 relative to the conveying inclined plane 1151 is less than the length of the conveying inclined plane 1151, so as to realize the friction cleaning of the garbage by the cleaning belt 24. In some embodiments, in the first stage, the cleaning belt 24 can clean the garbage on the introduction part 116 and / or the conveying inclined plane 1151 by means of a cleaning liquid.

[0097] In some embodiments, the length of the conveying inclined plane 1151 can be the straight-line distance between the upper and lower ends of the conveying inclined plane 1151, or the distance extended between the upper and lower ends of the conveying inclined plane 1151.

[0098] In some embodiments, in the second stage of the self-cleaning mode, the second roller 22 can rotate continuously in the first direction or the second direction, while driving the cleaning belt 24 to rotate. The displacement of the cleaning belt 24 relative to the conveying inclined plane 1151 is greater than the length of the conveying inclined plane 1151. In some embodiments, in the second stage, when the cleaning belt 24 rotates continuously in the first direction, it can clean the garbage remaining on the introduction part 116 and / or the conveying inclined plane 1151, and the cleaning belt 24 can be cleaned by the scraper 30, or the cleaning belt 24, the introduction part 116 and / or the conveying inclined plane 1151 can be cleaned by means of a cleaning liquid. In some embodiments, in the second stage, when the cleaning belt 24 rotates continuously in the second direction, the cleaning belt 24 can be cleaned by the scraper 30, or the cleaning belt 24 can be cleaned by means of a cleaning liquid.

[0099] When Figure 6 the cleaning module 20 in contacts the surface to be cleaned, the working mode can be started. The second roller 22 can rotate continuously in the first direction, while driving the cleaning belt 24 to rotate, with the forward direction as the traveling direction. At the same time, the cleaning belt 24 cooperates with the introduction part 116 and the conveying inclined plane 1151 to realize garbage transfer, and the introduction part 116 and the conveying inclined plane 1151 have a good supporting effect on the cleaning belt 24, without wind power drive, which is beneficial to reducing the noise and cost of the cleaning main body 103.

[0100] Please refer to Figure 4 and Figure 5 , the scraper 30 can be arranged on the base 11 and used to press against the cleaning belt 24 to clean the garbage on the cleaning belt 24, so that the garbage drops off.

[0101] Please refer to Figure 6, the squeegee 30 can be installed on the base 11, such as the top wall 112, and can be pressed against the cleaning belt 24 respectively.

[0102] The squeegee 30 can be arranged above the dropping port 1004 and can press the cleaning belt 24 against the outer peripheral surface of the first roller 21. The squeegee 30 can clean the garbage on the cleaning belt 24, so that the garbage drops and enters the storage space 1003 from the dropping port 1004. In some embodiments, the interference amount between the squeegee 30 and the cleaning belt 24 is greater than or equal to 30% of the natural thickness of the fluff layer 242. The interference amount refers to the part where the squeegee 30 intersects or overlaps with the cleaning belt 24.

[0103] The squeegee 30 can be arranged at the rear side of the cleaning belt 24. In some embodiments, the squeegee 30 can be used to clean the garbage on the cleaning belt 24 in the working mode or the self-cleaning mode. In some embodiments, the squeegee 30 can be used to clean the garbage on the cleaning belt 24 and can also be used to comb and restore the fluff layer 242 in the self-cleaning mode. For example, in the second stage of the self-cleaning mode, the second roller 22 can rotate continuously in the second direction, and the squeegee 30 can comb the fluff layer 242 to make the cleaning belt 24 return to the natural state as much as possible.

[0104] It can be understood that in the working mode, the cleaning belt 24 can rotate in the first direction, and the squeegee 30 can scrape the fluff layer 242, so that the fluff on the fluff layer 242 is tilted in the second direction. In the second stage of the cleaning mode, the squeegee 30 can scrape the fluff layer 242 and comb the fluff tilted in the second direction on the fluff layer 242 in the first direction, so that the fluff on the fluff layer 242 can be reopened. At the same time, the garbage remaining in the fluff layer 242 can also be cleaned.

[0105] In an alternative embodiment, the second axis and the first axis are the same axis.

[0106] In addition, with the cooperation of the squeegee 30, when the second roller 22 rotates in the second direction, the cleaning belt 24 exerts a force F1 on the squeegee 30 (as Figure 9 shown), and the squeegee 30 can generate a force F2 opposite to the force F1 on the cleaning belt 24 (as Figure 9 shown), so that the link assembly 23 swings under the action of the force F2, and the second roller 22 presses the cleaning belt 24 against the transfer inclined surface 1151, making the contact more sufficient and improving the self-cleaning ability.

[0107] Please refer to Figure 6 , the storage box 40 can be placed in the storage space 1003 to receive the garbage. When the garbage enters from the dropping port 1004, it can directly fall into the storage box 40.

[0108] The base 11 can form a placement opening, and the placement opening can communicate with the storage space 1003. The storage box 40 can extend into the storage space 1003 from the placement opening. In some embodiments, the placement opening can be formed at the rear side of the base 11 when the bottom wall 111, the top wall 112, the first side wall 113, and the second side wall 114 enclose.

[0109] In some embodiments, the storage box 40 can be inserted into the base 11 and can be connected to the base 11.

[0110] In some embodiments, the bottom wall 111 can be reduced in size, so that the bottom of the storage box 40 acts as the bottom wall 111 and cooperates with the bottom wall 111 as the bottom of the cleaning main body 103, which can reduce the size of the cleaning main body 103 or make the storage box 40 have a deeper garbage cavity.

[0111] In some embodiments, the storage box 40 can be omitted, and the storage space 1003 can be directly used to hold garbage. In some embodiments, the storage box 40 can also be part of the main frame 10. In some embodiments, the storage box 40 can also be an integral structure with the base 11.

[0112] Please refer to Figure 5 and Figure 6 , the edge 117 of the dropping opening 1004 can facilitate the entry of garbage into the storage space 1003. Furthermore, the size of the edge 117 can determine the size of the garbage to be collected. Furthermore, the collection of large particulate matter, large strip-shaped objects and other garbage can be achieved by controlling the edge 117.

[0113] Please refer to Figure 6 and Figure 9 , Figure 9 For Figure 6 is a partial structural schematic diagram of the cleaning main body 103 in the illustrated embodiment. The edge 117 can include a first front-side edge 1171 near the upper end of the conveying inclined surface 1151 and a first rear-side edge 1172 far from the upper end of the conveying inclined surface 1151. Among them, the first front-side edge 1171 and the first rear-side edge 1172 are oppositely arranged. The distance between the first front-side edge 1171 and the first rear-side edge 1172 can determine the size of the garbage to be collected. Furthermore, the collection of large particulate matter, large strip-shaped objects and other garbage can be achieved by controlling the distance between the first front-side edge 1171 and the first rear-side edge 1172.

[0114] In some embodiments, the first front-side edge 1171 can be arranged on the conveying part 115.

[0115] In some embodiments, the first rear-side edge 1172 can be arranged on the main frame 10, such as the base 11. In some embodiments, the first rear-side edge 1172 can be arranged on the top wall 112.

[0116] Please refer to Figure 6 , since the cleaning module 20 swings as the link assembly 23 swings, when the collected garbage is particulate matter, the size of the garbage is restricted by the distance between the upper end of the transfer inclined plane 1151 and the periphery of the first roller 21. Specifically, the minimum distance between the upper end of the transfer inclined plane 1151 and the periphery of the first roller 21 is the first minimum distance L. During the process of the cleaning module 20 swinging as the link assembly 23 swings, the position of the first roller 21 does not change. Therefore, the first minimum distance L does not change during the swinging of the link assembly 23. Thus, whether the garbage can pass through between the upper end of the transfer inclined plane 1151 and the first roller 21 is affected by the first minimum distance L. Further, when the cleaning module 20 is swingable, the cleaning belt 24 is also swingable. Thus, the natural thickness of the cleaning belt 24 can also affect the size of the collected garbage. Further, according to the design parameters of the garbage cleaning by the cleaning main body 103, the size of the collected garbage can be generally limited to the difference between the distance from the upper end of the transfer inclined plane 1151 to the periphery of the first roller 21 and the natural thickness of the cleaning belt 24. The natural thickness of the cleaning belt 24 can be measured in the second state.

[0117] Please refer to Figure 9 , the minimum distance between the upper end of the transfer inclined plane 1151 and the periphery of the first roller 21 is the first minimum distance L, and the minimum distance between the first front edge 1171 and the first rear edge 1172 is the second minimum distance M. Thus, the size of the garbage collected by the cleaning main body 103 can be restricted by the first minimum distance L and the second minimum distance M, and further can also be restricted by the natural thickness of the cleaning belt 24. Then, in order to enable the cleaning main body 103 to collect large garbage, it can be achieved by adjusting the first minimum distance L, the second minimum distance M, and the natural thickness of the cleaning belt 24.

[0118] In some embodiments, the first front edge 1171 can be formed by the upper end of the transfer inclined plane 1151. Thus, the second minimum distance M can be the minimum distance between the upper end of the transfer inclined plane 1151 and the first rear edge 1172.

[0119] In some embodiments, by matching the design of the edge 41 of the dropping port 1004, the upper end of the transfer inclined plane 1151, and the position of the first roller 21, the second minimum distance L at the dropping port 1004 is better matched with the first minimum distance M, so as to make the internal structure of the cleaning device 101 more compact and reasonable as much as possible and reduce redundancy.

[0120] In some embodiments, the ratio of the first minimum distance L to the second minimum distance M is between 0.7 and 1.3.

[0121] In some embodiments, the difference between the first minimum distance L and the natural thickness of the cleaning belt 24 is less than the second minimum distance M. By balancing the relationship among the first minimum distance L, the second minimum distance M, and the natural thickness of the cleaning belt 24, the situation where large garbage is conveyed to the upper end of the transfer inclined plane 1151, gets stuck at the rim 117, and cannot enter the storage box 40 is improved. By improving the interference of the second minimum distance M on large garbage, the cleaning main body 103 can collect large garbage as much as possible, highlighting the feature that the cleaning device 101 can clean large garbage. The natural thickness of the cleaning belt 24 can be measured in the second state.

[0122] In some embodiments, when the cleaning belt 24 is squeezed, the thickness of the cleaning belt 24 will be adjusted from the natural thickness to the incompressible thickness, and the difference between the first minimum distance L and the incompressible thickness of the cleaning belt 24 can be further less than the second minimum distance M. Optionally, the incompressible thickness of the cleaning belt 24 is greater than or equal to 3 mm and less than or equal to 5 mm.

[0123] In some embodiments, the first minimum distance L is between 18 - 26 mm. When the interference of the second minimum distance M on large garbage is small or even has no effect, the size of the garbage collected by the cleaning main body 103 is defined by the first minimum distance L.

[0124] In some embodiments, the first minimum distance L is not less than 22 mm.

[0125] In some embodiments, the first minimum distance L can be 22 mm.

[0126] In some embodiments, the first minimum distance L is less than the second minimum distance M.

[0127] Please refer to Figure 4 and Figure 6 , the storage box 40 has a box opening 4001, and the box opening 4001 can be docked with the dropping opening 1004, so that the garbage enters the storage box 40 in sequence through the dropping opening 1004 and the box opening 4001.

[0128] The storage box 40 has a rim 41 at the box opening 4001. When the box opening 4001 can be docked with the dropping opening 1004, the rim 41 can be docked with the rim 117 to realize the cooperation between the storage box 40 and the base 11.

[0129] In some embodiments, the rim 41 may include a second front side rim 411 and a second rear side rim 412. When the rim 41 is docked with the rim 117, the second front side rim 411 can be cooperatively docked with the first front side rim 1171, and the second rear side rim 412 can be cooperatively docked with the first rear side rim 1172.

[0130] Please refer to Figure 9, the minimum distance between the second front mouth edge 411 and the second rear mouth edge 412 is the third minimum distance N. Furthermore, the size of the garbage collected by the cleaning main body 103 can also be limited by the third minimum distance N. Further, it can be simultaneously limited by the first minimum distance L, the second minimum distance M, the natural thickness of the cleaning belt 24, and the third minimum distance N. Then, in order to enable the cleaning main body 103 to collect large garbage, it can also be achieved by adjusting the third minimum distance N.

[0131] The third minimum distance N can improve the situation where large garbage is transported to the upper end of the transfer inclined plane 1151 and gets stuck at the box opening 4001 and cannot enter the storage box 40. By improving the interference of the second minimum distance M on large garbage, the cleaning main body 103 can collect large garbage as much as possible, highlighting the feature of the cleaning device 101 for cleaning large garbage.

[0132] In some embodiments, the first minimum distance L is less than the third minimum distance N, which can prevent the box opening 4001 from being too large, resulting in an increase in the volume of the cleaning main body 103 and reducing redundancy. Of course, it can also prevent the liquid garbage in the storage box 40 from shaking out due to the overly large box opening 4001.

[0133] In some embodiments, the third minimum distance N can be greater than the second minimum distance M, less than the second minimum distance M, or equal to the second minimum distance M.

[0134] In some embodiments, when the third minimum distance N is greater than the second minimum distance M, the second front mouth edge 411 can be located on the side of the first front mouth edge 1171 close to the transfer inclined plane 1151, and the second rear mouth edge 412 can be located on the side of the first rear mouth edge 1172 away from the transfer inclined plane 1151, so that the mouth edge 41 is docked with the mouth edge 117, reducing the probability of liquid garbage directly entering the gap between the storage box 40 and the base 11 from the drop opening 1004. Of course, it can also facilitate improving the sealing performance between the storage box 40 and the base 11.

[0135] In some embodiments, the display of the cleaning main body 103 in the reference section perpendicular to the support plane PL can be as Figure 6As shown in the figure. On a reference cross-section perpendicular to the support plane PL, the line connecting the upper and lower ends of the transfer inclined plane 1151 is line X1, and the line connecting the first front-side edge 1171 and the first rear-side edge 1172 is line X2. The angle formed by line X1 and the support plane PL can be greater than the angle formed by line X2 and the support plane PL. When the overall volume of the cleaning main body 103 is fixed, that is, under the condition of the height and the front-back length of the cleaning main body 103, by adjusting the angle formed by line X2 and the support plane PL, the adjustment of the second minimum distance M can be realized, so as to maximize the second minimum distance M as much as possible. It can be understood that in all embodiments of the present application, the reference cross-section perpendicular to the support plane PL can also be perpendicular to the first axis and / or the second axis and / or the third axis at the same time. In some embodiments, the reference cross-section perpendicular to the support plane PL can also be parallel to the front-back direction at the same time.

[0136] Please refer to Figure 9 , a first guiding surface 118 is provided on the transfer part 115. The first guiding surface 118 is adjacent to the first front-side edge 1171, and thus can guide the garbage, so that the garbage is conveyed from the upper end of the transfer inclined plane 1151 to the dropping port 1004.

[0137] Please refer to Figure 9 , a second guiding surface 1121 is provided on the base 11. The second guiding surface 1121 is adjacent to the first rear-side edge 1172, and thus can guide the garbage, so that the garbage is conveyed to the dropping port 1004. In some embodiments, when the scraper 30 cleans the cleaning belt 24, the fallen garbage can be guided by the second guiding surface 1121 and conveyed to the dropping port 1004.

[0138] In some embodiments, the second guiding surface 1121 can be provided on the top wall 112.

[0139] In some embodiments, the first rear-side edge 1172 is higher than the first front-side edge 1171. Since the garbage can have inertia driven by the cleaning belt 24, it can then hit the second guiding surface 1121. The second guiding surface 1121 guides the garbage, so that the garbage is conveyed to the dropping port 1004. In addition, the first rear-side edge 1172 being higher than the first front-side edge 1171 can make the storage box 40 have a deeper garbage cavity.

[0140] In some embodiments, the second front-side edge 411 is located below the first guiding surface 118, which is convenient for the first guiding surface 118 to guide the garbage, so that the garbage is conveyed into the storage box 40. Further, setting the second front-side edge 411 below the first guiding surface 118 can reduce the probability of liquid garbage directly entering the gap between the storage box 40 and the base 11 from the dropping port 1004. Of course, it can also facilitate improving the sealing performance between the storage box 40 and the base 11.

[0141] In some embodiments, the second rear edge 412 is located at the rear side of the second guiding surface 1121, facilitating the second guiding surface 1121 to guide the garbage, so that the garbage is conveyed into the storage box 40. Since the garbage is conveyed from the conveying inclined surface 1151 to the side close to the second guiding surface 1121, the second rear edge 412 is arranged at the rear side of the second guiding surface 1121, which can reduce the probability of liquid garbage directly entering the gap between the storage box 40 and the base 11 from the dropping port 1004. Of course, it can also facilitate improving the sealing performance between the storage box 40 and the base 11.

[0142] Please refer to Figure 9 , the minimum distance from the upper end of the conveying inclined surface 1151 to the abutting position of the scraper 30 on the cleaning belt 24 is the fourth minimum distance P. Since the garbage collected by the cleaning module 20 can also be in the form of strips or flakes, the length of the garbage collected by the cleaning module 20 can be limited by the fourth minimum distance P. Further, according to the design parameters of the garbage cleaning by the cleaning main body 103, the length of the collected garbage can be generally limited to the fourth minimum distance P. Then the length of the garbage collected by the cleaning main body 103 can be limited by the second minimum distance M and the fourth minimum distance P. In order to enable the cleaning main body 103 to collect longer garbage, it can be achieved by adjusting the second minimum distance M and the fourth minimum distance P.

[0143] In some embodiments, the second minimum distance M is greater than the fourth minimum distance P. By balancing the relationship between the second minimum distance M and the fourth minimum distance P, the situation that longer garbage is conveyed to the upper end of the conveying inclined surface 1151 and gets stuck at the edge 117 and cannot enter the storage box 40 is improved. By improving the interference of the second minimum distance M on the longer garbage, the cleaning main body 103 can collect large garbage as much as possible, highlighting the feature of the cleaning device 101 for cleaning large garbage.

[0144] Please refer to Figure 9 , an installation part 1122 is arranged on the base 11, and the installation part 1122 can be used to install the scraper 30. In some embodiments, the installation part 1122 is arranged adjacent to the upper end of the second guiding surface 1121. When the scraper 30 cleans the cleaning belt 24, the fallen garbage can be guided by the second guiding surface 1121 and conveyed into the dropping port 1004.

[0145] In some embodiments, at least part of the second guiding surface 1121 is recessed toward the side away from the upper end of the conveying inclined surface 1151 to realize the conveying of the garbage and reduce the interference of the second guiding surface 1121 on the longer garbage. In some embodiments, the middle part of the second guiding surface 1121 is recessed toward the side away from the upper end of the conveying inclined surface 1151.

[0146] In some embodiments, the second introduction surface 1121 may intersect with an extended surface of the conveying slope 1151 to reduce the interference of the second introduction surface 1121 with the longer garbage.

[0147] In some embodiments, the first minimum distance L is smaller than the radius of the second roller 22. The second roller 22 can pass over the garbage, and the radius of the second roller 22 determines whether the garbage can be passed over and collected. When the first minimum distance L defines the size of the garbage collected by the cleaning body 103, it is particularly necessary to define the first minimum distance L to be smaller than the radius of the second roller 22. In addition, the smaller the difference between the radius of the second roller 22 and the size of the garbage, the more difficult it is to pass over the garbage, and the larger the difference between the radius of the second roller 22 and the size of the garbage, the easier it is to pass over the garbage.

[0148] In some embodiments, the ratio of the first minimum distance L to the radius of the second roller 22 is limited to 0.8-0.95, which can reduce the size of the second roller 22, avoid the cleaning body 103 from becoming larger and heavier, and reduce redundancy. In some embodiments, the ratio of the first minimum distance L to the radius of the second roller 22 is limited to 0.82, 0.84, 0.86, 0.90 or 0.92, etc.

[0149] See also Figure 8 The second roller 22 presses the cleaning belt 24 against the introduction portion 116 and / or the conveying inclined surface 1151. Furthermore, the length of the cleaning body 103 in the front-to-back direction is limited by the cooperation between the second roller 22 and the conveying inclined surface 1151.

[0150] See also Figure 10 , Figure 10 for Figure 8 The transmission part 115 in some embodiments is shown in the embodiment. The transmission part 115 on the reference cross section perpendicular to the support plane PL can be shown as follows: Figure 10 shown.

[0151] In a reference cross-section perpendicular to the support plane PL, the transfer inclined plane 1151 may include a first transfer section 1152 disposed adjacent to the lower end of the transfer inclined plane 1151. The first transfer section 1152 may be disposed opposite to the second roller 22 so that the second roller 22 can press the cleaning belt 24 against the first transfer section 1152. Then, when the first transfer section 1152 is recessed toward the side away from the second roller 22, the second roller 22 can extend into the recessed area. When the cleaning main body 103 is supported by the surface to be cleaned, the recessed area on the first transfer section 1152 corresponds to the second roller 22. Compared with the case where the first transfer section 1152 is not recessed, the recessed area on the first transfer section 1152 can reduce the supporting force of the first transfer section 1152 on the second roller 22 and the cleaning belt 24, so that the second roller 22 and the cleaning belt 24 are supported by the surface to be cleaned as much as possible, improving the cleaning effect of the cleaning main body 103 on the surface to be cleaned. In addition, the recessed area on the first transfer section 1152 allows the second roller 22 to extend into the recessed area, thereby reducing the length of the cleaning main body 103 in the front-rear direction, making the cleaning main body 103 miniaturized and facilitating the user to operate the cleaning device 101.

[0152] In some embodiments, both the upper and lower ends of the first transfer section 1152 may be disposed between the upper and lower ends of the transfer inclined plane 1151. In some embodiments, the upper end of the first transfer section 1152 may be the upper end of the transfer inclined plane 1151. In some embodiments, the lower end of the first transfer section 1152 may be the lower end of the transfer inclined plane 1151.

[0153] Please refer to Figure 11 , Figure 11 For Figure 8 the structural schematic diagram of the cooperation of the cleaning module 20 with the transfer part 115 and the introduction part 116 in the illustrated embodiment. The display of the cleaning module 20, the transfer part 115, and the introduction part 116 in a reference cross-section perpendicular to the support plane PL may be as shown in Figure 11 shown.

[0154] In a reference cross-section perpendicular to the support plane PL, the first transfer section 1152 may be arc-shaped to match the arc-shaped outer periphery of the second roller 22. In some embodiments, the ratio of the sum of the radius of the second roller 22 and the thickness of the cleaning belt 24 in the natural state to the radius of curvature of the first transfer section 1152 is between 0.8 and 1.1, which can enable the first transfer section 1152 to better adapt to the shape of the second roller 33, so that the second roller 22 can press the cleaning belt 24 against the first transfer section 1152 for sufficient contact, improving the cleaning effect of the cleaning main body 103. The thickness of the cleaning belt 24 in the natural state can be measured in the second state.

[0155] In some embodiments, the ratio of the sum of the radius of the second roller 22 and the thickness of the cleaning belt 24 in the natural state to the radius of curvature of the first conveying section 1152 may be 0.8, 0.83, 0.85, 0.89, 0.9, 0.92, 0.96, 0.98, 1, 1.02, 1.04, 1.08, 1.1, etc.

[0156] In some embodiments, the sum of the radius of the second roller 22 and the thickness of the cleaning belt 24 in the natural state may be slightly smaller than the radius of curvature of the first conveying section 1152. As a result, when the cleaning belt 24 is pressed against the first conveying section 1152, the cleaning belt 24 can better conform to the first conveying section 1152 and thus can better convey garbage.

[0157] In some embodiments, the third axis O1 of the second roller 22 coincides with the center O2 of the first conveying section 1152, so that the second roller 22 can press the cleaning belt 24 against the first conveying section 1152 for sufficient contact, improving the cleaning effect of the cleaning main body 103.

[0158] In some embodiments, the third axis O1 of the second roller 22 does not coincide with the center O2 of the first conveying section 1152. Instead, the extension line of the perpendicular connection line between the center O2 of the first conveying section 1152 and the third axis O1 of the second roller 22 can pass through the position where the cleaning belt 24 abuts against the first conveying section 1152.

[0159] Please refer to Figure 12 , Figure 12 for Figure 8 the schematic structural diagram of the cooperation of the cleaning module 20 with the conveying part 115 and the introducing part 116 in the illustrated embodiment. The display of the cleaning module 20, the conveying part 115, and the introducing part 116 in the reference cross-section perpendicular to the support plane PL can be as shown in Figure 12 the figure.

[0160] In the reference cross-section perpendicular to the support plane PL, the ratio of the distance Q from the center O2 of the first conveying section 1152 to the third axis O1 to the radius R1 of the second roller 22 is less than or equal to 0.3. In some embodiments, when the ratio of the distance Q to the radius R1 of the second roller 22 is 0, the third axis O1 of the second roller 22 can coincide with the center O2 of the first conveying section 1152. In some embodiments, the ratio of the distance Q to the radius R1 of the second roller 22 is 0.03, 0.06, 0.09, 0.12, 0.15, 0.18, 0.21, 0.24, 0.27, or 0.29.

[0161] In some embodiments, when designing the cleaning body 103, the third axis O1 of the second roller 22 can be made to coincide with the center O2 of the first conveying section 1152. However, during the assembly and production process, there are inevitable errors, which lead to the existence of the distance Q. The ratio between the distance Q and the radius R1 of the second roller 22 can determine the coordination effect between the cleaning module 20 and the first conveying section 1152. The error can be reduced and the cleaning effect of the cleaning body 103 can be improved by limiting the ratio between the distance Q and the radius R1 of the second roller 22.

[0162] In addition, the distance Q also defines the distribution of interference between the cleaning belt 24 and the first conveying section 1152. Figure 12 In the embodiment, the center O2 is biased backwards compared to the third axis O1, so that the portion with a larger interference amount between the cleaning belt 24 and the first conveying section 1152 is close to the upper end of the first conveying section 1152. Furthermore, the center O2 is biased forwards compared to the third axis O1, so that the portion with a larger interference amount between the cleaning belt 24 and the first conveying section 1152 is close to the lower end of the first conveying section 1152. Furthermore, the distribution of the interference amount between the cleaning belt 24 and the first conveying section 1152 can be adjusted by the distance Q.

[0163] See also Figure 13 , Figure 13 for Figure 12 The cleaning module 20, the conveying part 115 and the introduction part 116 in some embodiments are shown in the schematic diagram of the structure of the cleaning module 20, the conveying part 115 and the introduction part 116 in some embodiments. The display of the cleaning module 20, the conveying part 115 and the introduction part 116 on the reference section perpendicular to the support plane PL can be as follows: Figure 13 shown.

[0164] A first reference line CK1 and a second reference line CK2 are provided on a reference section perpendicular to the support plane PL. The first reference line CK1 passes through the third axis O1 and is perpendicular to the support plane PL, the second reference line CK2 passes through the third axis O1 and the upper end of the first conveying section 1152, and the angle c between the first reference line CK1 and the second reference line CK2 is between 50-85°. The size of the angle c can determine the length of the first conveying section 1152, and thus the angle c needs to be limited to avoid the excessive length of the first conveying section 1152 as much as possible, reduce redundancy, and also reduce the influence of the excessive length of the first conveying section 1152 on the cleaning effect of the cleaning body 103. The length of the first conveying section 1152 can be reasonably set by the angle c, so that the first conveying section 1152 preferentially matches the second roller 22.

[0165] In some embodiments, the angle c is 52°, 55°, 58°, 60°, 63°, 65°, 67°, 68°, 70°, 73°, 76°, 78°, 79°, 80°, 82° or 84°, etc.

[0166] Please refer to Figure 10 , on the reference section perpendicular to the support plane PL, the connection line between the point on the first transfer section 1152 and the lower end of the transfer inclined plane 1151 forms a first included angle a1 with the reference plane PL1, and the first included angle a1 is between 48.6 - 52.5°. The reference plane PL1 is arranged parallel to the support plane PL. The maximum value of the first included angle a1 can be determined based on the upper end and / or the lower end of the first transfer section 1152. Furthermore, the maximum value of the first included angle a1 can be the included angle between the transfer inclined plane 1151 and the support plane PL, or the included angle between other transfer sections on the transfer inclined plane 1151 and the support plane PL. The minimum value of the first included angle a1 determines the degree of depression of the first transfer section 1152, and the span between the minimum value and the maximum value of the first included angle a1 determines the form of the recessed setting of the first transfer section 1152. In some embodiments, the first included angle a1 is 49°, 49.5°, 50°, 50.5°, 51°, 51.5° or 52°.

[0167] Please refer to Figure 10 , on the reference section perpendicular to the support plane PL, the connection line between the upper and lower ends of the transfer inclined plane 1151 forms a second included angle a2 with the reference plane PL1, and the difference between the second included angle a2 and the first included angle a1 is between 4 - 13°. In some embodiments, the difference between the second included angle a2 and the first included angle a1 is 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12° or 13°, etc.

[0168] In some embodiments, the smaller the difference between the second included angle a2 and the first included angle a1, the smoother the transfer inclined plane indicates. The interference amount distribution between the cleaning belt 24 and the transfer inclined plane 1151 can be adjusted by the difference between the second included angle a2 and the first included angle a1, the gap between the cleaning belt 24 and the transfer inclined plane 1151 can be reduced, and the cleaning effect of the cleaning main body 103 can be improved.

[0169] Please refer to Figure 10 , on the reference section perpendicular to the support plane PL, the ratio of the chord length of the first transfer section 1152 to the length between the upper and lower ends of the transfer inclined plane 1151 is between 0.3 - 0.6. By the ratio of the chord length of the first transfer section 1152 to the length between the upper and lower ends of the transfer inclined plane 1151, the size and the maximum degree of depression of the first transfer section 1152 are defined, and further, the length of the cleaning main body 103 in the front - rear direction can be adjusted.

[0170] In some embodiments, on the reference section perpendicular to the support plane PL, the ratio of the chord length of the first transfer section 1152 to the length between the upper and lower ends of the transfer inclined plane 1151 is 0.33, 0.35, 0.38, 0.4, 0.42, 0.45, 0.47, 0.5, 0.52, 0.55 or 0.58, etc.

[0171] In some embodiments, on a reference cross-section perpendicular to the support plane PL, the chord length of the first conveying section 1152 is between 8 - 12 mm. In some embodiments, on a reference cross-section perpendicular to the support plane PL, the chord length of the first conveying section 1152 is between 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, or 11.5 mm, etc.

[0172] Please refer to Figure 10 , on a reference cross-section perpendicular to the support plane PL, the conveying inclined plane 1151 may further include a second conveying section 1153, and the lower end of the second conveying section 1153 may be connected to the upper end of the first conveying section 1152. In some embodiments, the upper end of the second conveying section 1153 may be disposed between the upper end of the conveying inclined plane 1151 and the upper end of the first conveying section 1152. In some embodiments, the upper end of the second conveying section 1153 may be the upper end of the conveying inclined plane 1151.

[0173] In some embodiments, on a reference cross-section perpendicular to the support plane PL, the second conveying section 1153 may be recessed toward the side away from the cleaning belt 24 to reduce the interference amount between the second conveying section 1153 and the cleaning belt 24. Additionally, it can also enable the cleaning module 20 to be supported by the surface to be cleaned as much as possible in the working mode, improving the cleaning effect of the cleaning main body 103. In some embodiments, on a reference cross-section perpendicular to the support plane PL, the second conveying section 1153 may be arc-shaped to improve the conveying effect of the garbage.

[0174] In some embodiments, on a reference cross-section perpendicular to the support plane PL, the radius of curvature of the second conveying section 1153 is greater than that of the first conveying section 1152 to control the interference degree between the second conveying section 1153 and the cleaning belt 24.

[0175] In some embodiments, on a reference cross-section perpendicular to the support plane PL, the second conveying section 1153 may be a plane. The upper end and / or the lower end of the first conveying section 1152 may be located on the extension plane of the second conveying section 1153. In some embodiments, on a reference cross-section perpendicular to the support plane PL, the second conveying section 1153 may be a plane. The upper end and / or the lower end of the first conveying section 1152 may be located on the side of the extension plane of the second conveying section 1153 away from the second roller 22, so as to further reduce the length of the cleaning main body 103 in the front-back direction, enabling the cleaning main body 103 to be miniaturized and facilitating the user to operate the cleaning device 101.

[0176] In some embodiments, the upper end of the first conveying section 1152 and the lower end of the second conveying section 1153 may be smoothly and transitionally connected, or connected through other conveying sections.

[0177] Please refer to Figure 14 ,Figure 14 In Figure 8 the embodiment shown, it is a schematic structural diagram of the cooperation of the cleaning module 20 with the conveying part 115 and the introducing part 116 in some embodiments. The display of the cleaning module 20, the conveying part 115, and the introducing part 116 in a reference section perpendicular to the support plane PL can be as shown in Figure 14 the figure

[0178] The conveying inclined plane 1151 may have a connected first inclined plane section 1156 and a second inclined plane section 1157. Compared with the first inclined plane section 1156, the second inclined plane section 1157 may be closer to the upper end of the conveying inclined plane 1151. Compared with the second inclined plane section 1157, the first inclined plane section 1156 may be closer to the lower end of the conveying inclined plane 1151.

[0179] In some embodiments, the lower end of the first inclined plane section 1156 may be the lower end of the conveying inclined plane 1151, and the upper end of the second inclined plane section 1157 may be the upper end of the conveying inclined plane 1151.

[0180] In some embodiments, the first inclined plane section 1156 may be provided with the first conveying section 1152 in the above embodiment. In some embodiments, the first inclined plane section 1156 may be the first conveying section 1152 in the above embodiment. In some embodiments, the second inclined plane section 1157 may be provided with the second conveying section 1153 in the above embodiment. In some embodiments, the second inclined plane section 1157 may be the second conveying section 1153 in the above embodiment.

[0181] Please refer to Figure 15 , Figure 15 In Figure 14 the embodiment shown, it is a schematic structural diagram of the conveying part 115. The display of the conveying part 115 in a reference section perpendicular to the support plane PL can be as shown in Figure 15 the figure

[0182] In a reference section perpendicular to the support plane PL, the connection line of the upper and lower ends of the first inclined plane section 1156 forms a first angle b1 with the reference plane PL2, the connection line of the upper and lower ends of the second inclined plane section 1157 forms a second angle b2 with the reference plane PL1, and the connection line 1158 of the lower end of the first inclined plane section 1156 and the upper end of the second inclined plane section 1157 forms a third angle b3 with the reference plane PL1. The first angle b1 is less than the third angle b3, and the third angle b3 is less than the second angle b2. The reference plane PL2 is arranged parallel to the support plane PL.

[0183] In Figure 14 it, the first inclined plane section 1156 can be set only based on the first angle b1, and the first inclined plane section 1156 can replace the second inclined plane section 1157 and be implemented into Figure 6In the cleaning body 103, the transfer inclined plane 1151 cooperates with the cleaning module 20, such as the cleaning belt 24, to convey the garbage to the dropping port 1004. The acting force at the contact part between the transfer inclined plane 1151 and the cleaning module 20 becomes smaller, and the cleaning module 20 is supported by the surface to be cleaned as much as possible in the working mode. However, this will increase the gap between the upper part of the transfer inclined plane 1151 and the cleaning module 20, such as the cleaning belt 24. As a result, when the upper part of the transfer inclined plane 1151 cooperates with the cleaning module 20, such as the cleaning belt 24, it is impossible to convey the garbage smaller than the gap. Furthermore, by cooperating the second inclined plane section 1157 with the cleaning module 20, such as the cleaning belt 24, the ability to convey the garbage is improved.

[0184] Figure 15 In [the relevant part], the first inclined plane section 1156 is set based on the first included angle b1, and the second inclined plane section 1157 is set based on the second included angle b2, which can reduce the acting force at the contact part between the transfer inclined plane 1151 and the cleaning module 20, and the cleaning module 20 is supported by the surface to be cleaned as much as possible in the working mode. At the same time, the second inclined plane section 1157 also reduces the gap between the upper part of the transfer inclined plane 1151 and the cleaning module 20, such as the cleaning belt 24. As a result, when the upper part of the transfer inclined plane 1151 cooperates with the cleaning module 20, such as the cleaning belt 24, it is possible to convey the smaller garbage.

[0185] In some embodiments, please refer to Figure 15 , the difference between the second included angle b2 and the first included angle b1 is between 1 - 10 degrees. In the working mode, in order to reduce the acting force between the surface to be cleaned and the cleaning module 20 supported by the second inclined plane section 1157, it is necessary to limit the second included angle b2. In addition, the selection of the garbage size can be realized by adjusting the difference, and the garbage of the preset target size can be cleaned. In some embodiments, the difference between the second included angle b2 and the first included angle b1 is 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, 5.5°, 6°, 6.5°, 7°, 7.5°, 8°, 8.5° or 9°, etc.

[0186] In some embodiments, please refer to Figure 15 , the first included angle b1 is between 48 - 54 degrees, which can improve the cooperation state between the first inclined plane section 1156 and the cleaning module 20 in the working mode. In addition, the supporting effect on the cleaning module 20 can also be adjusted by adjusting the first included angle b1. In some embodiments, the first included angle b1 is 48.5°, 49°, 49.5°, 50°, 50.5°, 51°, 51.5°, 52°, 52.5°, 53.5° or 53°.

[0187] In some embodiments, the ratio of the length of the line connecting the upper and lower ends of the first inclined surface segment 1156 to the length of the line connecting the upper and lower ends of the second inclined surface segment 1157 is between 0.5 and 1.5. The second included angle b2 can be adjusted by adjusting the ratio, and further, the cooperation between the second inclined surface segment 1157 and the cleaning module 20, such as the cleaning belt 24, can be adjusted to realize the conveyance of smaller garbage. In addition, the cleaning main body 103 can be miniaturized by adjusting the ratio, which is convenient for the user to control the cleaning device 101. In some embodiments, the ratio of the length of the line connecting the upper and lower ends of the first inclined surface segment 1156 to the length of the line connecting the upper and lower ends of the second inclined surface segment 1157 is 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3, 1.35, 1.4 or 1.45, etc.

[0188] Please refer to Figure 15 , since the upper end of the first inclined surface segment 1156 is connected to the lower end of the second inclined surface segment 1157, in order to ensure the effective contact between the cleaning belt 24 and the conveying inclined surface 1151 and realize garbage conveyance, the cleaning belt 24 can be made to contact the lower end of the first inclined surface segment 1156 and the upper end of the second inclined surface segment 1157. Furthermore, the outer surface of the fluff layer 242 provided on the base layer 241 can be parallel to the line connecting the lower end of the first inclined surface segment 1156 and the upper end of the second inclined surface segment 1157. The upper end of the first inclined surface segment 1156 and the lower end of the second inclined surface segment 1157 must be the parts farthest from the base layer 241. Therefore, the fluff layer 242 needs to contact the upper end of the first inclined surface segment 1156 and the lower end of the second inclined surface segment 1157. The ratio of the perpendicular distance from the upper end of the first inclined surface segment 1156 or the lower end of the second inclined surface segment 1157 to the line 1158 to the fluff length of the fluff layer 242 is between 0.7 and 0.9. The effective contact between the conveying inclined surface 1151 and the cleaning belt 24 is realized by adjusting the ratio.

[0189] In some embodiments, to ensure effective contact between the cleaning belt 24 and the conveying inclined plane 1151 and achieve waste conveying, the cleaning belt 24 can be made to contact the lower end of the first inclined plane section 1156 and the upper end of the second inclined plane section 1157. Then, between the lower end of the first inclined plane section 1156 and the upper end of the second inclined plane section 1157, the change amount of the interference amount of the conveying inclined plane 1151 on the fluff layer 242 (the difference between the maximum interference amount and the minimum interference amount of the conveying inclined plane 1151 on the fluff layer 242) and the ratio of the maximum interference amount (the maximum interference amount of the conveying inclined plane 1151 on the fluff layer 242) are between 0.2 and 0.7. By adjusting the ratio, effective contact between the conveying inclined plane 1151 and the cleaning belt 24 can be achieved, and the cleaning ability can also be improved by adjusting the ratio. In some embodiments, the measurements of the maximum interference amount and the minimum interference amount of the conveying inclined plane 1151 on the fluff layer 242 need to be carried out in the same state among the above-mentioned first state, second state, and third state. In some embodiments, the measurements of the maximum interference amount and the minimum interference amount of the conveying inclined plane 1151 on the fluff layer 242 need to be carried out in the second state.

[0190] Please refer to Figure 14 , on the side of the first roller 21 and the second roller 22 close to the conveying inclined plane 1151, there is a common tangent plane PM, and the common tangent plane PM forms a fourth included angle b4 with the reference plane PL3. The reference plane PL3 is parallel to the support plane PL. When the cleaning belt 24 is pressed by the second roller 22 against the surface to be cleaned, the fourth included angle b4 is less than the second included angle b2 and greater than the first included angle b1. Thus, effective contact between the second inclined plane section 1157 and the cleaning belt 24 can be achieved, the cleaning ability can be improved, and in addition, the pressure of the cleaning module 20 on the first inclined plane section 1156 can be reduced, so that the cleaning module 20 is supported by the surface to be cleaned as much as possible.

[0191] In some embodiments, when the second roller 22 is suspended, the second roller 22 can be in a suspended state. The second roller 22 can press the cleaning belt 24 against the conveying inclined plane 1151, so that the cleaning main body 103 can enter the self-cleaning mode. The fourth included angle b4 is greater than the second included angle b2, which can increase the acting force between the conveying inclined plane 1151 and the cleaning module 20 for self-cleaning to ensure the self-cleaning effect.

[0192] In some embodiments, the absolute value of the difference between the second included angle b2 and the first included angle b1 and the difference between the fourth included angle b4 when the second roller 22 is suspended and the angle change amount when the cleaning belt 24 is pressed by the second roller 22 against the surface to be cleaned is between 1° and 7° to ensure effective contact between the transfer inclined surface 1151 and the cleaning belt 24. In some embodiments, the absolute value of the difference between the second included angle b2 and the first included angle b1 and the difference between the fourth included angle b4 when the second roller 22 is suspended and the angle change amount when the cleaning belt 24 is pressed by the second roller 22 against the surface to be cleaned is 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, 5.5°, 6° or 6.5°, etc. It can be understood that when the second roller 22 is suspended, the second roller 22 can be in a suspended state.

[0193] In some embodiments, the first inclined surface segment 1156 and the second inclined surface segment 1157 can be smoothly connected in a transitional manner, or connected through other inclined surface segments. In some embodiments, the first inclined surface segment 1156 and the second inclined surface segment 1157 are connected in an arc-shaped transitional manner.

[0194] Please refer to Figure 1 and Figure 16 , Figure 16 is Figure 1 a schematic cross-sectional view of the cleaning system 100 at the line XV-XV in the illustrated embodiment. A bearing surface 1021 is provided on the base station 102, and the bearing surface 1021 can be used to support the cleaning main body 103. When placing the cleaning main body 103 on the base station 102, it can be specifically placed on the bearing surface 1021.

[0195] Please refer to Figure 16 , when the cleaning main body 103 is placed on the bearing surface 1021, the cleaning module 20 can be in a suspended state. The cleaning main body 103 can start the self-cleaning mode, causing the second roller 22 to rotate, and further driving the cleaning belt 24 to rotate. Of course, the second roller 22 can also press the cleaning belt 24 against the base station 102, and make part of the cleaning module 20 located below the support plane PL, and then the self-cleaning mode can be started, causing the second roller 22 to rotate, and further driving the cleaning belt 24 to rotate.

[0196] It can be understood that (1) in the working mode, Figure 16 the cleaning main body 103 in is not placed on the bearing surface 2001, but on the surface to be cleaned. The cleaning module 20 is in contact with the surface to be cleaned, and the link assembly 23 can drive the second roller 22 and the cleaning belt 24 to swing in a direction away from the transfer inclined surface 1151, so that the cleaning module 20 is located on the support plane PL. At this time, based on the surface to be cleaned sharing at least part of the gravity of the cleaning module 20, the contact effect between the cleaning belt 24 and the transfer inclined surface 1151 is worse than that in the self-cleaning mode.

[0197] (2) In the self-cleaning mode, Figure 16 the cleaning body 103 therein is placed on the bearing surface 2001 and is in contact with the bearing surface 2001. The cleaning module 20 is in contact with the bearing surface 2001. The link assembly 23 can drive the second roller 22 and the cleaning belt 24 to swing, and can further swing in the direction closer to the conveying inclined plane 1151 on the basis of the above (1), so that part of the cleaning module 20 is located below the support plane PL. At this time, the acting force between the bearing surface 2001 and the cleaning module 20 is smaller than the acting force between the surface to be cleaned and the cleaning module 20 in the above (1). The contact effect between the cleaning belt 24 and the conveying inclined plane 1151 at this time is better than that in the above (1). Furthermore, the self-cleaning mode can be further started. In the self-cleaning mode, the cleaning efficiency can be improved, and the removal rate of the accumulated garbage of the cleaning device 101 can be improved.

[0198] (3) In the self-cleaning mode, Figure 16 the cleaning body 103 therein is placed on the bearing surface 2001 and is in contact with the bearing surface 2001. The cleaning module 20 is arranged at an interval from the bearing surface 2001. The link assembly 23 can drive the second roller 22 and the cleaning belt 24 to swing, and can further swing in the direction closer to the conveying inclined plane 1151 on the basis of the above (2), so that part of the cleaning module 20 is located below the support plane PL. At this time, the acting force between the bearing surface 2001 and the cleaning module 20 is 0. The contact effect between the cleaning belt 24 and the conveying inclined plane 1151 at this time is better than that in the above (1) and (2). Furthermore, the self-cleaning mode can be further started. In the self-cleaning mode, the cleaning efficiency is improved, and the removal rate of the accumulated garbage of the cleaning device 101 is improved.

[0199] Please refer to Figure 16 , a storage groove 1022 is provided on the base station 102. When the cleaning body 103 is supported on the bearing surface 1021, at least part of the projection of the second roller 22 in the direction of gravity falls into the storage groove 1022. The cleaning belt 24 wound around the second roller 22 extends into the storage groove 1022 and is arranged at an interval from the groove wall of the storage groove 1022.

[0200] In some embodiments, the receiving groove 1022 may be provided on the bearing surface 1021 and extend downward below the support plane PL to be spaced apart from the cleaning belt 24 wound around the second roller 22. In some embodiments, the receiving groove 1022 may be omitted, and the cleaning module 20, such as the second roller 22 and the cleaning belt 24, may be kept in a suspended state by other means. In some embodiments, the cleaning belt 24 wound around the second roller 22 extends into the receiving groove 1022 and contacts the groove wall of the receiving groove 1022, and the cleaning module 20 is limited by the receiving groove 1022. In some embodiments, the cleaning belt 24 wound around the second roller 22 extends into the receiving groove 1022, and the second roller 22 presses the cleaning belt 24 against the groove wall of the receiving groove 1022, and the cleaning module 20 is limited by the receiving groove 1022. In some embodiments, when the cleaning belt 24 wound around the second roller 22 extends into the receiving groove 1022 and is spaced apart from the groove wall of the receiving groove 1022, the receiving groove 1022 can receive the garbage dropped on the cleaning belt 24 and also the garbage sliding down from the transfer slope 1511.

[0201] Optionally, by keeping the cleaning module 20 in a suspended state and spaced apart from the groove wall of the receiving groove 1022, at this time the cleaning belt 24 does not contact the groove wall of the receiving groove 1022. When the cleaning belt 24 rotates in the first direction, it will not form a frictional force away from the transfer slope 1151 with the groove wall of the receiving groove 1022, and thus will not have a moment away from the transfer slope 1151, thereby ensuring the pressure of the cleaning module 20 on the transfer slope 1151 and effectively improving the cleaning strength.

[0202] In some embodiments, Figure 16 the cleaning main body 103 is placed on the bearing surface 1021, and the cleaning belt 24 wound around the second roller 22 extends into the receiving groove 1022 and is spaced apart from the groove wall of the receiving groove 1022, so that the cleaning module 20 is in a suspended state. Relative to Figure 6 when the cleaning main body 103 is placed on the surface to be cleaned and supported by the surface to be cleaned, Figure 16 when the cleaning module 20 in the suspended state can swing under the link assembly 23, structures in the cleaning module 20 other than the cleaning belt 24, such as the second roller 22, press the cleaning belt 24 against the guiding portion 116 and / or the transfer slope 1151, so that the supporting force of the guiding portion 116 and / or the transfer slope 1151 on the cleaning module 20 becomes larger, and the distance between the cleaning belt 24 and the guiding portion 116 and / or the transfer slope 1151 is adjusted to facilitate the cleaning of the garbage on the guiding portion 116 and / or the transfer slope 1151 in the self-cleaning mode.

[0203] On one side edge of the base station 102, a guiding inclined surface 1023 connected to the bearing surface 1021 is provided. Further, the cooperation between the bearing surface 1021 and the surface to be cleaned or the ground can be achieved through the guiding inclined surface 1023, so that the cleaning main body 103 can roll from the surface to be cleaned or the ground to the guiding inclined surface 1023 under the rolling of the wheel body 13, and further roll onto the bearing surface 1021 to realize the placement of the cleaning main body 103.

In some embodiments, one of the first limiting groove 1025 and the second limiting groove 1026 can be omitted. In some embodiments, on a reference section perpendicular to the support plane PL defined by the front wheel body 131 and the rear wheel body 132, the groove wall of the first limiting groove 1025 is arranged in an arc shape adapted to the outer peripheral surface of the front wheel body 131, which can better limit the front wheel body 131 and reduce the occurrence of the shaking of the cleaning main body 103. Of course, when the user controls the cleaning main body 103, it is also convenient for the front wheel body 131 to slide out of the first limiting groove 1025. In some embodiments, on a reference section perpendicular to the support plane PL defined by the front wheel body 131 and the rear wheel body 132, the groove wall of the second limiting groove 1026 is arranged in an arc shape adapted to the outer peripheral surface of the rear wheel body 132, which can better limit the rear wheel body 132 and reduce the occurrence of the shaking of the cleaning main body 103. Of course, when the user controls the cleaning main body 103, it is also convenient for the rear wheel body 132 to slide out of the second limiting groove 1026.

[0206] In some embodiments, the first limiting groove 1025 is disposed adjacent to the receiving groove 1022, and the depression depth of the first limiting groove 1025 is smaller than that of the receiving groove 1022. In some embodiments, the receiving groove 1022 may be formed at the bottom of the first limiting groove 1025, so as to guide the garbage in the first limiting groove 1025 to the receiving groove 1022. In some embodiments, the first limiting groove 1025 is closer to the receiving groove 1022 than the second limiting groove 1026.

[0207] A limiting protrusion 1027 may be provided on the base station 102. When the cleaning main body 103 is placed on the base station 102, the limiting protrusion 1027 can cooperate with the cleaning main body 103 to limit the cleaning main body 103, and can keep the cleaning main body 103 stable and non-shaking when the cleaning main body 103 starts the self-cleaning mode, thereby ensuring the use safety of the cleaning main body 103. In some embodiments, the limiting protrusion 1027 may be a part of the limiting mechanism 1024. In some embodiments, the limiting protrusion 1027 may be provided corresponding to the card slot 1111. When the cleaning main body 103 is placed on the base station 102, the limiting protrusion 1027 is located in the card slot 1111. In some embodiments, the setting positions of the limiting protrusion 1027 and the card slot 1111 can be interchanged. Furthermore, the card slot 1111 may also be a part of the limiting mechanism 1024. In some embodiments, the limiting protrusion 1027 can be omitted. In some embodiments, the limiting protrusion 1027 may be provided on the bearing surface 1021.

[0208] In some embodiments, the limiting protrusion 1027 may be located between the first limiting groove 1025 and the second limiting groove 1026.

[0209] In some embodiments, under the control of the user, the handle 104 can keep the front wheel body 131 suspended and the rear wheel body 132 slides. The cleaning main body 103 is pushed above the bearing surface 1021 along the guiding inclined surface 1023 by the rear wheel body 132. When the rear wheel body 132 moves to be limited by the limiting mechanism 1024 and the front wheel body 131 contacts the bearing surface 1021, the limiting protrusion 1027 extends into the card slot 1111. Of course, the manner of placing the cleaning main body 103 on the bearing surface 1021 is not limited to this, and it can also be through other ways, which will not be elaborated.
