[0024] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application and do not limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application and not all embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0026] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0027] This application describes a cleaning system that can be used in daily cleaning tasks and can clean a surface to be cleaned, such as particles, threads, debris, strips, flakes, liquids, stains, and other debris that can affect the cleanliness of the surface. The cleaning system can specifically clean debris that meets the design requirements based on the cleaning system's design requirements.

[0028] The surface to be cleaned may be on the ground, on stairs, on the floor, on a table, or on any other structure that may contain garbage and may need to be cleaned, which will not be elaborated here.

The cleaning system 100 may include a cleaning device 101 and a base station 102. The cleaning device 101 can be used to clean the surface to be cleaned and remove garbage on the surface to be cleaned. The base station 102 can be used to store the cleaning device 101. Of course, the cleaning device 101 may not be stored on the base station 102. In some embodiments, the cleaning device 101 may have an operating mode. In operating mode, the cleaning device 101 can be used to clean the surface to be cleaned. In some embodiments, the cleaning device 101 may have a self-cleaning mode. When the cleaning device 101 is placed on the base station 102, the cleaning device 101 can start the self-cleaning mode under the control of the user and / or intelligent control. When the cleaning device 101 is cleaning garbage, garbage may remain on part of the structure of the cleaning device 101 due to reasons such as being not transported into place or being solidified, adhered, or having a small size, causing part of the structure of the cleaning device 101 to become dirty. In the self-cleaning mode, the cleaning device 101 can be used to clean up garbage that is not transported to the correct location or is solidified, stuck, or small in size, and to clean part of its own structure. Of course, the cleaning device 101 can also perform the self-cleaning mode without the cooperation of the base station 102, but with the cooperation of other structures or users.

[0030] See also Figure 1 and Figure 2 , Figure 2 for Figure 1 Schematic diagram of the structure of the cleaning device 101 in the illustrated embodiment. The cleaning device 101 may include a cleaning body 103 and a handle 104. The cleaning body 103 may serve as the main body of the cleaning device 101 for cleaning the surface to be cleaned. The cleaning body 103 may be placed on the base station 102. The handle 104 may be connected to the cleaning body 103. The handle 104 may be gripped by a user. The user may control the cleaning body 103 via the handle 104 to perform cleaning and / or movement. In some embodiments, the cleaning body 103 and the handle 104 may cooperate to accommodate liquid, batteries, a processor, a control panel and / or control buttons, etc. for cleaning.

[0031] exist Figure 2 In the embodiment, the user can hold the handle 104 to control the cleaning body 103 to move in the front-back direction, such as forward movement, backward movement, or back-and-forth movement. Of course, the cleaning body 103 can also be controlled to move in a turning direction.

The storage box 40 can collect and store the trash.

[0035] The main frame 10 may include a base 11, a flip cover 12, and a wheel 13. The flip cover 12 and wheel 13 may be mounted on the base 11. The base 11 may form an installation space 1001 for mounting the cleaning module 20, the scraper 30, and the storage box 40. The flip cover 12 is connected to the base 11. The wheel 13 enables the base 11 to move over the surface to be cleaned.

[0036] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0037] See also Figure 3 、 Figure 4 and Figure 5 , Figure 5 for Figure 4Schematic diagram of the structure of the base 11 and the scraper 30 in the illustrated embodiment. The base 11 may 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 arranged opposite to each other. The first side wall 113 and the second side wall 114 are arranged opposite to each other. The bottom wall 111, the first side wall 113, the top wall 112 and the second side wall 114 can be connected in sequence. 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 formed by at least the bottom wall 111, the top wall 112, the first side wall 113 and the second side wall 114.

[0038] Of course, in some embodiments, the base 11 may further include other side walls, which will not be described in detail.

[0039] In some embodiments, Figure 3 The bottom wall 111 of the base 11 is provided with a slot 1111 for cooperating with the base 102 for positioning and limiting, thereby improving the stability of the cleaning body 103 when placed on the base 102. In some scenarios, the slot 1111 can also be provided on other structures in the base 11, such as the first side wall 113 and the second side wall 114. Of course, the slot 1111 can also be provided on other structures in the cleaning body 103 according to design requirements, which will not be described in detail here.

[0040] In some embodiments, Figure 3 A first electrical connection terminal 1131 is provided on the first side wall 113, so that the cleaning device 101, such as the cleaning body 103, is electrically connected to the base station 102 or other equipment via the first electrical connection terminal 1131, thereby enabling charging of the cleaning device 101, and enabling the cleaning device 101 to control the base station 102 or other equipment. Of course, the cleaning device 101 can also interact with the base station 102 or other equipment, and further, the system upgrade or maintenance of the cleaning device 101, such as the cleaning body 103, can be achieved. Of course, the first electrical connection terminal 1131 can also be selectively provided at other locations of the cleaning device 101, such as the cleaning body 103, according to the needs of those skilled in the art.

[0041] It is understandable that the structural arrangement of the base 11 is not limited to the above embodiment, and the structural arrangement can also be performed in other ways, which will not be described in detail.

[0042] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , Figure 6 for Figure 3 A schematic cross-sectional view of the cleaning body 103 at line VI-VI in the embodiment shown, Figure 7 for Figure 6 The cleaning body 103 is shown as a schematic diagram of the structure of the cleaning body 103 on the surface to be cleaned in the embodiment shown. The base 11 is provided with a conveying portion 115 inside the installation space 1001. The conveying portion 115 can cooperate with the cleaning module 20 to pick up and / or transport garbage.

[0043] In some embodiments, the conveyor 115 can scrape the surface to be cleaned to collect garbage. In some embodiments, the conveyor 115 can cooperate with the cleaning module 20 to pick up garbage on the surface to be cleaned. In some embodiments, the conveyor 115 can cooperate with the cleaning module 20 to transport garbage to the storage box 40.

[0044] The conveyor unit 115 can divide the installation space 1001 into a storage space 1002 and a storage space 1003. The storage space 1002 is located at the front of the conveyor unit 115 and is used to accommodate the cleaning module 20. The storage space 1003 is located at the rear of the conveyor unit 115 and is used to accommodate the storage box 40. The conveyor unit 115 can cooperate with the cleaning module 20 to transport garbage from the storage space 1002 to the storage space 1003.

[0045] A conveying slope 1151 is provided on the front side of the conveying portion 115 . The conveying slope 1151 can cooperate with the cleaning module 20 so that garbage can be transported from the lower end of the conveying slope 1151 to the upper end of the conveying slope 1151 .

[0046] The upper end of the conveying slope 1151 is further back than the lower end of the conveying slope 1151, while the lower end of the conveying slope 1151 is further forward than the upper end of the conveying slope 1151. The combination of the slope of the conveying slope 1151 and the parameters of the upper end of the conveying slope 1151 can ensure that the cleaning body 103 meets the garbage conveying capacity while ensuring the garbage conveying height, so that the storage box 40 has a deeper garbage cavity.

[0047] The base 11 is provided with a drop opening 1004. The drop opening 1004 is provided near the upper end of the conveying inclined surface 1151 and can connect the accommodating space 1002 and the storage space 1003. When the garbage is at the upper end of the conveying inclined surface 1151, it can fall from the drop opening 1004 into the storage box 40 in the storage space 1003.

[0048] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The base 11 may be provided with an introduction portion 116 at the bottom of the conveying portion 115. The introduction portion 116 is located on one side of the conveying inclined surface 1151 extending toward the surface to be cleaned. In some embodiments, the introduction portion 116 may contact the surface to be cleaned or may be slightly spaced from the surface to be cleaned.

[0049] The introduction portion 116 can be used to perform at least one of the following functions: scraping garbage on the surface to be cleaned, cooperating with the cleaning module 20 to pick up garbage on the surface to be cleaned, and cooperating with the cleaning module 20 to transfer garbage to the transfer slope 1151.

[0050] The introduction portion 116 can be disposed near the lower end of the conveying inclined surface 1151, and the surface of the introduction portion 116 that cooperates with the cleaning module 20 can be transitionally connected to the conveying inclined surface 1151. The introduction portion 116 can cooperate with the cleaning module 20 to clean the garbage on the surface to be cleaned and can transport the garbage to the conveying inclined surface 1151.

[0051] 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 gathers 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 transport the garbage to the conveying slope 1151.

[0052] In some embodiments, when the delivery portion 115 can achieve at least some of the capabilities of the introduction portion 116 , the introduction portion 116 may be omitted.

[0053] See also Figure 4 、 Figure 6 and Figure 7 The flip cover 12 can be used to realize the inspection, 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.

[0054] The front side of the base 11 may form an assembly opening, and the flip cover 12 may be disposed on the assembly opening to cover the assembly opening. The assembly opening may be communicated with the accommodating space 1002.

[0055] In some embodiments, the assembly opening can be formed on 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 are surrounded. In some embodiments, the assembly opening can be provided on the top wall 112.

[0056] It is understood that the terms "first," "second," and so on, used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0057] In some embodiments, the flip cover 12 may 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 may be a part of the base 11 .

[0058] See also Figure 3The wheel 13 can be mounted on the base 11, such as the bottom wall 111. The wheel 13 can roll, thereby enabling the movement of the cleaning body 103. In some embodiments, a motor can be installed in the cleaning body 103 to drive the wheel 13 to rotate. In some embodiments, the wheel 13 can also be mounted on other structures in the base 11, such as the first side wall 113 and the second side wall 114, which will not be described in detail.

[0059] The wheel body 13 is provided to form a support plane PL (such as Figure 6 shown).

[0060] 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 positioned forward of the rear wheel body 132, while the rear wheel body 132 is positioned rearward of the front wheel body 131. In some embodiments, the retaining groove 1111 may be located between the front wheel body 131 and the rear wheel body 132. In some embodiments, the guide portion 116 may be positioned forward of the front wheel body 131. In some embodiments, the forward direction may be the direction of travel.

[0061] 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.

[0062] 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 arranged in an annular shape and is wound around the periphery of the first roller 21 and the second roller 22. When the first roller 21 and / or the second roller 22 rotate, the cleaning belt 24 is driven to rotate.

[0063] The first roller 21 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 first roller 21 can also be rotatably connected to other parts of the base 11.

[0064] In some embodiments, the first roller 21 may be disposed adjacent to an upper end of the conveying slope 1151. In some embodiments, the first roller 21 may be located above the drop opening 1004.

[0065] 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.

[0066] 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.

[0067] 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 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.

[0068] In some embodiments, the connecting rod assembly 23 may not be rotatably connected to the base 11, but may be 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 may be 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.

[0069] In some embodiments, the first roller 21 and the connecting rod assembly 23 can both rotate about a first axis. In some embodiments, the first roller 21 can rotate about the first axis, and the connecting rod assembly 23 can rotate about a second axis. The second axis is parallel to the first axis.

[0070] In some embodiments, the second axis may be coaxial with the first axis or may be non-coaxial with the first axis, that is, the second axis and the first axis are on the same line.

[0071] 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 arranged adjacent to the lower end of the conveying inclined surface 1151.

[0072] The cleaning belt 24 may be pressed against the front side of the introduction portion 116 and / or the conveying inclined surface 1151 , or may be pressed against the surface to be cleaned.

[0073] When the cleaning belt 24 rotates, it can clean the garbage on the surface to be cleaned, and can cooperate with the introduction part 116 to clean and pick up the garbage on the surface to be cleaned, and can transport the garbage to the conveying inclined surface 1151. The cleaning belt 24 cooperates with the conveying inclined surface 1151 to transport the garbage from the lower end of the conveying inclined surface 1151 to the upper end of the conveying inclined surface 1151, and further transport it to the storage box 40.

[0074] 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, when the cleaning body 103 is placed on the surface to be cleaned, the connecting rod assembly 23 can swing to support the cleaning module 20 as much as possible from the surface to be cleaned, so that the second roller 22 presses the cleaning belt 24 against the surface to be cleaned. In some embodiments, when the cleaning body 103 cleans the garbage on the surface to be cleaned, it will come into contact with the garbage and can be supported by the garbage. Then, the connecting rod assembly 23 can swing to lift the second roller 22 and the cleaning belt 24 over 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.

[0075] See also Figure 8 , Figure 8 for Figure 6 Schematic diagram of the structure of the middle cleaning module 20 cooperating with the conveying part 115 and the introduction part 116. The cleaning belt 24 may include a base layer 241 wound around the periphery of the first roller 21 and the second roller 22, and a fluff layer 242 arranged 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, enabling the arrangement of the cleaning belt 24 on the first roller 21 and the second roller 22, and is used to arrange the fluff layer 242. The fluff layer 242 serves as the cleaning layer of the cleaning belt 24. When the cleaning belt 24 is subjected to force, the fluff layer 242 will be subjected to force to generate interference, causing the fluff layer 242 to be compressed. The arrangement of the fluff layer 242 can enhance the cleaning ability of the cleaning belt 24.

[0076] It should be noted that no matter what state the cleaning belt 24 is in, the length of the fluff layer 242 remains unchanged when it is not worn. 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 is in a naturally stretched state.

[0077] The cleaning belt 24 described in this application may be in three states:

[0078] In the first state, the cleaning belt 24 is in the factory state. The cleaning belt 24 is not soaked by liquid and is in a dry state. At this time, the fluff layer 242 is relatively fluffy. When the fluff layer 242 is pressed against the floor to be cleaned, it will be greatly deformed.

[0079] In the second state, the cleaning tape 24 has been running for a period of time after leaving the factory, and the cleaning tape 24 is not wetted by liquid and is in a dry state, for example, along a fixed direction (for example, Figure 6 The fleece layer 242 is relatively compacted when the fleece layer 242 is pressed against the floor to be cleaned, and the degree of deformation is relatively reduced.

[0080] In the third state, the cleaning belt 24 is operated for at least 5 hours after leaving the factory, and the cleaning belt 24 is soaked with liquid. When the cleaning belt 24 is pressed against the floor to be cleaned, the degree of deformation is further reduced.

[0081] Furthermore, in the description of this application, the interference amount of any component on the pile layer 242 refers to the difference between the pile length of the pile layer 242 and the distance between the component and the base layer 241. 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 pile layer 242.

[0082] In the above-mentioned second state, the cleaning belt 24 is naturally wound on the first roller 32 and the second roller 33, and can be considered to be in a natural state when it is not subject to force (for example, the force between the ground to be cleaned, the conveying part 115 or the inlet part 116), and thus the cleaning belt 24 and the fluff layer 242 can both have a natural thickness (also called "thickness in the natural state").

[0083] See also Figure 6 and Figure 7 When the cleaning module 20 is not in contact with the surface to be cleaned, the connecting rod assembly 23 can swing, allowing a portion of the cleaning module 20, such as the cleaning belt 24, to be positioned below the support plane PL. At this point, the cleaning belt 24 can be pressed against the introduction portion 116 and / or the conveying ramp 1151 due to the weight of the cleaning module 20. Of course, the second roller 22 can also be partially positioned below the support plane PL, or the entire second roller 22 can be positioned above the support plane PL.

[0084] Optionally, the cleaning module 20 mentioned in this application is located below the support plane PL. 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 part of the cleaning module 20, that is, part of the cleaning belt 24 is located below the support plane PL, or part of the cleaning module 20, that is, part of the cleaning belt 24 is located below the support plane PL. There is no limitation here.

[0085] When the cleaning module 20 contacts 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 may deviate from the support plane PL, but it can still be supported by the surface to be cleaned. At this time, because the gravity of the cleaning module 20 is shared by the surface to be cleaned, when the cleaning belt 24 presses against the introduction portion 116 and / or the conveying inclined surface 1151, the pressure of the cleaning belt 24 on the introduction portion 116 and / or the conveying inclined surface 1151 is reduced compared to the case where the cleaning module 20 is not in contact with the surface to be cleaned.

[0086] In addition, compared to the case where the cleaning module 20 contacts the surface to be cleaned, the cleaning module 20 not contacting the surface to be cleaned can further increase the interference between the cleaning belt 24 and the introduction portion 116 and / or the transmission slope 1151 .

[0087] See also Figure 6 and Figure 7 The cleaning module 20 does not contact the surface to be cleaned, the second roller 22 and the cleaning belt 24 do not contact the surface to be cleaned and are in a suspended state, and then the cleaning body 103 can start the self-cleaning mode and clean the introduction part 116 and / or the conveying inclined surface 1151 through the cleaning belt 24.

[0088] It is understood that the suspended state refers to a state in which the second roller 22 and the cleaning belt 24 are not in contact with structures outside the cleaning device 101, but are supported by the cleaning device 101, such as the introduction portion 116 and / or the conveying inclined surface 1151. At this time, the cleaning module 20 can also be said to be in a suspended state.

[0089] As an option, in some scenarios, the cleaning module 20 is supported on the introduction portion 116 and / or the conveying slope 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 spaced apart from the surface to be cleaned.

[0090] 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. The cleaning belt 24 can then clean the inlet 116 and / or the conveying inclined surface 1151, and further remove the garbage remaining on the inlet 116 and / or the conveying inclined surface 1151 and transport it to the storage box 40.

[0091] In some embodiments, the first direction may be Figure 6 in the counterclockwise direction.

[0092] 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. The cleaning belt 24 can then clean the inlet portion 116 and / or the conveying inclined surface 1151, and further remove the garbage remaining on the inlet portion 116 and / or the conveying inclined surface 1151, and transport it to the storage box 40 when the cleaning belt 24 rotates in the first direction.

[0093] In some embodiments, the second direction may be Figure 6 Clockwise direction in .

[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. Then, the cleaning belt 24 can be cleaned by the scraper 30 to achieve cleaning of the cleaning belt 24.

[0095] 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. The cleaning belt 24 can then be cleaned by the cleaning liquid, and the garbage on the introduction portion 116 and / or the conveying inclined surface 1151 can also be cleaned by the cleaning liquid.

[0096] In some embodiments, the self-cleaning mode may include multiple stages, and different cleaning tasks may be performed in different stages. When the self-cleaning mode is activated, at least one stage in the self-cleaning mode may be performed.

[0097] In some embodiments, during the first stage of the self-cleaning mode, the second roller 22 can rotate alternately in a first direction and a second direction opposite the first direction, simultaneously driving the cleaning belt 24 to rotate, thereby removing trash remaining on the inlet 116 and / or the conveyor ramp 1151, thereby improving the removal of difficult-to-remove trash. In some embodiments, during the first stage, the displacement of the cleaning belt 24 relative to the conveyor ramp 1151 is less than the length of the conveyor ramp 1151, thereby achieving frictional removal of trash by the cleaning belt 24. In some embodiments, during the first stage, the cleaning belt 24 can clean trash on the inlet 116 and / or the conveyor ramp 1151 using a cleaning liquid.

[0098] In some embodiments, the length of the conveying slope 1151 may be the straight-line distance between the upper and lower ends of the conveying slope 1151 , or may be the distance extended between the upper and lower ends of the conveying slope 1151 .

[0099] In some embodiments, during the second stage of the self-cleaning mode, the second roller 22 may continuously rotate in the first direction or the second direction, while driving the cleaning belt 24 to rotate, and the displacement of the cleaning belt 24 relative to the conveying ramp 1151 is greater than the length of the conveying ramp 1151. In some embodiments, during the second stage, the cleaning belt 24 continuously rotates in the first direction to clean up garbage remaining on the introduction portion 116 and / or the conveying ramp 1151, and the cleaning belt 24 may be cleaned by the scraper 30, or the cleaning belt 24, the introduction portion 116, and / or the conveying ramp 1151 may be cleaned by a cleaning liquid. In some embodiments, during the second stage, the cleaning belt 24 continuously rotates in the second direction to clean the cleaning belt 24 by the scraper 30, or the cleaning belt 24, the conveying ramp 1151 may be cleaned by a cleaning liquid.

[0100] when Figure 6When the cleaning module 20 contacts the surface to be cleaned, the operating mode is activated, and the second roller 22 continuously rotates in the first direction, simultaneously driving the cleaning belt 24 to rotate forward. Simultaneously, the cleaning belt 24 cooperates with the inlet 116 and the conveying ramp 1151 to convey the waste. The inlet 116 and the conveying ramp 1151 provide good support for the cleaning belt 24, eliminating the need for wind power, thereby reducing noise and costs associated with the cleaning body 103.

[0101] See also Figure 4 and Figure 5 The scraper 30 can be provided on the base 11 for pressing against the cleaning belt 24 to clean the garbage on the cleaning belt 24 so that the garbage falls off.

[0102] See also Figure 6 The scraper 30 can be installed on the base 11, such as the top wall 112, and can be pressed against the cleaning belt 24 respectively.

[0103] The scraper 30 can be positioned above the drop opening 1004 and can contact the cleaning belt 24 against the outer circumference of the first roller 21. The scraper 30 can remove trash from the cleaning belt 24, causing it to fall through the drop opening 1004 and enter the storage space 1003. In some embodiments, the amount of interference between the scraper 30 and the cleaning belt 24 can be greater than or equal to 30% of the natural thickness of the fluff layer 242. The interference refers to the portion where the scraper 30 and the cleaning belt 24 intersect or overlap.

[0104] The scraper 30 may be disposed on the rear side of the cleaning belt 24. In some embodiments, the scraper 30 may be used to clean debris from the cleaning belt 24 in either operating mode or self-cleaning mode. In some embodiments, the scraper 30 may be used to clean debris from the cleaning belt 24 in self-cleaning mode, or to comb and restore the lint layer 242. For example, in the second stage of the self-cleaning mode, the second roller 22 may continuously rotate in the second direction, and the scraper 30 may comb the lint layer 242 to restore the cleaning belt 24 to its natural state as much as possible.

[0105] It can be understood that in the working mode, the cleaning belt 24 can rotate in the first direction, and the scraper 30 can scrape the fluff layer 242 so that the fluff on the fluff layer 242 falls in the second direction. In the second stage of the cleaning mode, the scraper 30 can scrape the fluff layer 242 and comb the fluff on the fluff layer 242 that falls in the second direction toward 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.

[0106] In an alternative embodiment, the second axis is the same axis as the first axis.

[0107] In addition, with the cooperation of the scraper 30, when the second roller 22 rotates in the second direction, the cleaning belt 24 applies a force F1 (such as Figure 9 As shown in FIG), the scraper 30 can generate a force F2 (as shown in FIG) on the cleaning belt 24 that is opposite to the force F1. Figure 9 As shown), the connecting rod assembly 23 swings under the action of the force F2, and the second roller 22 presses the cleaning belt 24 against the conveying inclined surface 1151, so that the contact is more complete and the self-cleaning ability is improved.

[0108] See also Figure 6 The storage box 40 can be placed in the storage space 1003 to store garbage. When the garbage enters from the drop port 1004, it can directly fall into the storage box 40.

[0109] The base 11 may have a placement opening that communicates with the storage space 1003. The storage box 40 may extend through the placement opening into the storage space 1003. In some embodiments, the placement opening may be formed on the rear side of the base 11 when the bottom wall 111, top wall 112, first side wall 113, and second side wall 114 are enclosed.

[0110] In some embodiments, the storage box 40 can be inserted into the base 11 and can be connected to the base 11 .

[0111] In some embodiments, the bottom wall 111 can be reduced in size so that the bottom of the storage box 40 serves as the bottom wall 111, and together with the bottom wall 111 serves as the bottom of the cleaning body 103, which can reduce the size of the cleaning body 103 or make the storage box 40 have a deeper garbage cavity.

[0112] In some embodiments, the storage box 40 can be omitted and the storage space 1003 can be directly used to store garbage. In some embodiments, the storage box 40 can also be a part of the main frame 10. In some embodiments, the storage box 40 can also be an integrated structure with the base 11.

[0113] See also Figure 5 and Figure 6 The edge 117 of the drop port 1004 can facilitate the entry of garbage into the storage space 1003, and the size of the edge 117 can determine the size of the collected garbage, and the collection of large particles, large strips and other garbage can be achieved by controlling the edge 117.

[0114] See also Figure 6 and Figure 9 , Figure 9 for Figure 6A schematic diagram of a portion of the cleaning body 103 in the illustrated embodiment. The lip 117 may include a first front lip 1171 located near the upper end of the conveying ramp 1151 and a first rear lip 1172 located away from the upper end of the conveying ramp 1151. The first front lip 1171 and the first rear lip 1172 are disposed opposite each other. The distance between the first front lip 1171 and the first rear lip 1172 determines the size of the collected waste. By controlling the distance between the first front lip 1171 and the first rear lip 1172, large particles, large strips of waste, and other waste can be collected.

[0115] In some embodiments, the first front edge 1171 may be disposed on the conveying portion 115 .

[0116] In some embodiments, the first rear edge 1172 may be disposed on the main frame 10 , such as the base 11 . In some embodiments, the first rear edge 1172 may be disposed on the top wall 112 .

[0117] See also Figure 6 Because the cleaning module 20 swings with the swing of the connecting rod assembly 23, when the collected garbage is particulate matter, the size of the garbage is limited by the distance between the upper end of the conveying inclined surface 1151 and the outer periphery of the first roller 21. Specifically, the minimum distance between the upper end of the conveying inclined surface 1151 and the outer periphery of the first roller 21 is a first minimum distance L. While the cleaning module 20 swings with the swing of the connecting rod assembly 23, the position of the first roller 21 does not change, and thus the first minimum distance L does not change during the swing of the connecting rod assembly 23. Therefore, whether the garbage can pass between the upper end of the conveying inclined surface 1151 and the first roller 21 is affected by the first minimum distance L. Furthermore, when the cleaning module 20 is swingable, the cleaning belt 24 can also swing, and the natural thickness of the cleaning belt 24 can also affect the size of the collected garbage. Then, according to the design parameters of the cleaning body 103 for garbage cleaning, the size of the collected garbage can be roughly limited to the difference between the distance between the upper end of the conveying slope 1151 and the outer 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.

[0118] See also Figure 9The minimum distance between the upper end of the conveying slope 1151 and the outer periphery of the first roller 21 is a first minimum distance L, and the minimum distance between the first front edge 1171 and the first rear edge 1172 is a second minimum distance M. Consequently, the size of the garbage collected by the cleaning body 103 is limited by the first minimum distance L and the second minimum distance M, and further by the natural thickness of the cleaning belt 24. To enable the cleaning body 103 to collect large garbage, this can be achieved by adjusting the first minimum distance L, the second minimum distance M, and the natural thickness of the cleaning belt 24.

[0119] In some embodiments, the first front edge 1171 may be formed by the upper end of the conveying slope 1151 , and the second minimum distance M may be the minimum distance between the upper end of the conveying slope 1151 and the first rear edge 1172 .

[0120] In some embodiments, by matching the edge 41 of the drop port 1004, the upper end of the conveying slope 1151, and the position of the first roller 21, the second minimum distance L at the drop port 1004 is better matched with the first minimum distance M, making the internal structure of the cleaning device 101 more compact and reasonable as much as possible and reducing redundancy.

[0121] In some embodiments, a ratio of the first minimum distance L to the second minimum distance M is between 0.7 and 1.3.

[0122] 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 between 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 transported to the upper end of the conveying slope 1151 and becomes stuck at the edge 117, preventing it from entering the storage box 40, is improved. By reducing the interference of the second minimum distance M with large garbage, the cleaning body 103 is able to collect as much large garbage as possible, highlighting the cleaning device 101's ability to clean large garbage. The natural thickness of the cleaning belt 24 can be measured in the second state.

[0123] In some embodiments, when the cleaning tape 24 is squeezed, the thickness of the cleaning tape 24 is 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 tape 24 may be further smaller than the second minimum distance M. Optionally, the incompressible thickness of the cleaning tape 24 is greater than or equal to 3 mm and less than or equal to 5 mm.

[0124] In some embodiments, the first minimum distance L is between 18 and 26 mm. When the second minimum distance M has little interference with or even no effect on large garbage, the size of the garbage collected by the cleaning body 103 is limited by the first minimum distance L.

[0125] In some embodiments, the first minimum distance L may be no less than 22 mm.

[0126] In some embodiments, the first minimum distance L may be 22 mm.

[0127] In some embodiments, the first minimum distance L is less than the second minimum distance M.

[0128] See also Figure 4 and Figure 6 The storage box 40 has a box opening 4001, which can be docked with the drop opening 1004, so that garbage enters the storage box 40 through the drop opening 1004 and the box opening 4001 in sequence.

[0129] The storage box 40 has a rim 41 at the box opening 4001 . When the box opening 4001 can be docked with the drop opening 1004 , the rim 41 can be docked with the rim 117 , thereby achieving the matching between the storage box 40 and the base 11 .

[0130] In some embodiments, the rim 41 may include a second front rim 411 and a second rear rim 412. When the rim 41 is docked with the rim 117, the second front rim 411 may be docked with the first front rim 1171, and the second rear rim 412 may be docked with the first rear rim 1172.

[0131] See also Figure 9 The minimum distance between the second front edge 411 and the second rear edge 412 is the third minimum distance N. Therefore, the size of the garbage collected by the cleaning body 103 may also be limited by the third minimum distance N. Furthermore, the size of the garbage collected by the cleaning body 103 may also be 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. Therefore, in order to allow the cleaning body 103 to collect large garbage, the third minimum distance N can also be adjusted.

[0132] The third minimum distance N can improve the situation where large garbage is transported to the upper end of the conveying slope 1151, 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 body 103 can collect large garbage as much as possible, highlighting the feature of the cleaning device 101 in cleaning large garbage.

[0133] In some embodiments, the first minimum distance L is smaller than the third minimum distance N, which can prevent the box opening 4001 from being too large, causing the volume of the cleaning body 103 to increase, reducing redundancy, and of course, it can also prevent the box opening 4001 from being too large, causing liquid waste in the storage box 40 to be shaken out.

[0134] In some embodiments, the third minimum distance N may be greater than the second minimum distance M, may be less than the second minimum distance M, or may be equal to the second minimum distance M.

[0135] In some embodiments, the third minimum distance N may be greater than the second minimum distance M, so that the second front edge 411 is located on the side of the first front edge 1171 close to the conveying slope 1151, and the second rear edge 412 is located on the side of the first rear edge 1172 away from the conveying slope 1151, so that the edge 41 is docked with the edge 117, reducing the probability of liquid waste directly entering the gap between the storage box 40 and the base 11 from the drop port 1004, and of course it can also facilitate improving the sealing of the storage box 40 and the base 11.

[0136] In some embodiments, the display of the cleaning body 103 on the reference cross section perpendicular to the support plane PL may be as follows: Figure 6 As shown. On a reference cross section perpendicular to the support plane PL, the line connecting the upper and lower ends of the conveying inclined surface 1151 is line X1, and the line connecting the first front edge 1171 and the first rear 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. Within the overall volume of the cleaning body 103, that is, within the limits of the height and front-to-back length of the cleaning body 103, the second minimum distance M can be adjusted by adjusting the angle formed by line X2 and the support plane PL to maximize the second minimum distance M. It will 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. In some embodiments, the reference cross section perpendicular to the support plane PL can also be parallel to the front-to-back direction.

[0137] See also Figure 9 A first introduction surface 118 is provided on the conveying portion 115 , and the first introduction surface 118 is arranged adjacent to the first front side edge 1171 , thereby guiding the garbage so that the garbage is transported from the upper end of the conveying slope 1151 to the drop port 1004 .

[0138] See also Figure 9 The base 11 is provided with a second introduction surface 1121, which is disposed adjacent to the first rear edge 1172, thereby guiding the garbage so that the garbage is transported into the drop opening 1004. In some embodiments, when the scraper 30 cleans the cleaning belt 24, the garbage that falls off can be guided by the second introduction surface 1121 and transported into the drop opening 1004.

[0139] In some embodiments, the second introduction surface 1121 may be disposed on the top wall 112 .

[0140] In some embodiments, the first rear edge 1172 is higher than the first front edge 1171. As the garbage, driven by the cleaning belt 24, has inertia, it may collide with the second introduction surface 1121. The second introduction surface 1121 guides the garbage so that it is transported into the drop opening 1004. Furthermore, the first rear edge 1172 being higher than the first front edge 1171 allows the storage box 40 to have a deeper garbage cavity.

[0141] In some embodiments, the second front edge 411 is located below the first introduction surface 118, so that the first introduction surface 118 can guide the garbage and transport it into the storage box 40. Furthermore, the second front edge 411 is located below the first introduction surface 118 to reduce the probability of liquid garbage directly entering the gap between the storage box 40 and the base 11 through the drop opening 1004, and of course, it can also help improve the sealing between the storage box 40 and the base 11.

[0142] In some embodiments, the second rear edge 412 is located behind the second introduction surface 1121, so that the second introduction surface 1121 can guide the garbage and transport it into the storage box 40. Since the garbage is transported from the conveying inclined surface 1151 to the side closer to the second introduction surface 1121, the second rear edge 412 is located behind the second introduction surface 1121. This can reduce the probability of liquid garbage directly entering the gap between the storage box 40 and the base 11 through the drop opening 1004, and of course, it can also help improve the sealing between the storage box 40 and the base 11.

[0143] See also Figure 9 The minimum distance between the upper end of the conveying inclined surface 1151 and the contact position of the scraper 30 on the cleaning belt 24 is a fourth minimum distance P. Since the garbage collected by the cleaning module 20 may also be in the form of strips or sheets, the length of the garbage collected by the cleaning module 20 may be limited by the fourth minimum distance P. Furthermore, based on the design parameters of the cleaning body 103 for garbage cleaning, the length of the collected garbage may be generally limited to the fourth minimum distance P. Furthermore, the length of the garbage collected by the cleaning body 103 may be limited by the second minimum distance M and the fourth minimum distance P. Therefore, in order to enable the cleaning body 103 to collect longer garbage, the second minimum distance M and the fourth minimum distance P can be adjusted.

[0144] 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 in which longer garbage is transported to the upper end of the conveying slope 1151, stuck at the edge 117, and unable to enter the storage box 40 is improved. By improving the interference of the second minimum distance M with longer garbage, the cleaning body 103 can collect large garbage as much as possible, highlighting the feature of the cleaning device 101 in cleaning large garbage.

[0145] See also Figure 9 The base 11 is provided with a mounting portion 1122 for mounting the scraper 30. In some embodiments, the mounting portion 1122 is disposed adjacent to the upper end of the second introduction surface 1121, so that when the scraper 30 cleans the cleaning belt 24, the fallen garbage can be guided by the second introduction surface 1121 and transported into the drop port 1004.

[0146] In some embodiments, at least a portion of the second introduction surface 1121 is recessed away from the upper end of the conveying inclined surface 1151 to facilitate the conveying of waste and reduce interference with longer waste by the second introduction surface 1121. In some embodiments, the middle portion of the second introduction surface 1121 is recessed away from the upper end of the conveying inclined surface 1151.

[0147] In some embodiments, the second introduction surface 1121 may intersect with an extension of the conveying inclined surface 1151 to reduce interference of the second introduction surface 1121 with long garbage.

[0148] 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 garbage, and the radius of the second roller 22 determines whether it can pass over and collect the garbage. Therefore, when the first minimum distance L defines the size of the garbage collected by the cleaning body 103, it is particularly necessary to limit the first minimum distance L to be smaller than the radius of the second roller 22. Furthermore, 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; 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.

[0149] 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, minimize the size and weight of the cleaning body 103, 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.

[0150] 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 .

[0151] See also Figure 10 , Figure 10 for Figure 8 The structure diagram of the transmission part 115 in some embodiments is shown in the embodiment shown in FIG. The transmission part 115 is displayed on a reference cross section perpendicular to the support plane PL as shown in FIG. Figure 10 shown.

[0152] On a reference cross section perpendicular to the support plane PL, the conveying slope 1151 may include a first conveying section 1152 disposed adjacent to the lower end of the conveying slope 1151. The first conveying section 1152 may be disposed opposite the second roller 22 so that the second roller 22 can press the cleaning belt 24 against the first conveying section 1152. Therefore, when the first conveying 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 body 103 is supported by the surface to be cleaned, the recessed area on the first conveying section 1152 corresponds to the second roller 22. Compared to a case where the first conveying section 1152 does not have a recessed area, the recessed area on the first conveying section 1152 can reduce the supporting force of the first conveying section 1152 on the second roller 22 and the cleaning belt 24, thereby allowing the second roller 22 and the cleaning belt 24 to be supported as much as possible by the surface to be cleaned, thereby improving the cleaning effect of the cleaning body 103 on the surface to be cleaned. In addition, the recessed area on the first conveying section 1152 allows the second roller 22 to extend into the recessed area, thereby reducing the length of the cleaning body 103 in the front-to-back direction, miniaturizing the cleaning body 103 and facilitating user operation of the cleaning device 101.

[0153] In some embodiments, the upper and lower ends of the first conveying section 1152 may be disposed between the upper and lower ends of the conveying slope 1151. In some embodiments, the upper end of the first conveying section 1152 may be the upper end of the conveying slope 1151. In some embodiments, the lower end of the first conveying section 1152 may be the lower end of the conveying slope 1151.

[0154] See also Figure 11 , Figure 11 for Figure 8 The cleaning module 20, the conveying portion 115 and the introduction portion 116 are shown in the following diagrams: Figure 11 shown.

[0155] On a reference cross-section perpendicular to the support plane PL, the first conveying section 1152 can be arranged in an arc shape to match the arc-shaped 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 its natural state to the radius of curvature of the first conveying section 1152 is between 0.8 and 1.1. This allows the first conveying section 1152 to better adapt to the shape of the second roller 33, allowing the second roller 22 to press the cleaning belt 24 against the first conveying section 1152, achieving full contact and improving the cleaning effect of the cleaning body 103. The thickness of the cleaning belt 24 in its natural state can be measured in the second state.

[0156] 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 curvature radius 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 or 1.1, etc.

[0157] In some embodiments, the sum of the radius of the second roller 22 and the thickness of the cleaning belt 24 in its natural state can be slightly smaller than the curvature radius of the first conveying section 1152, so that when the cleaning belt 24 is pressed against the first conveying section 1152, the cleaning belt 24 can fit better with the first conveying section 1152 and can better guide the garbage.

[0158] 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 full contact, thereby improving the cleaning effect of the cleaning body 103 .

[0159] In some embodiments, the third axis O1 of the second roller 22 may not coincide with the center O2 of the first conveying section 1152, but the extension line of the vertical line connecting the center O2 of the first conveying section 1152 and the third axis O1 of the second roller 22 may pass through the position where the cleaning belt 24 abuts the first conveying section 1152.

[0160] See also Figure 12 , Figure 12 for Figure 8 The cleaning module 20, the conveying portion 115 and the introduction portion 116 are shown in the following diagrams: Figure 12 shown.

[0161] On a 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 and the center O2 of the first conveying section 1152 can coincide. 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.

[0162] 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.

[0163] In addition, the distance Q also defines the distribution of the interference between the cleaning belt 24 and the first conveying section 1152. Figure 12 In the embodiment, if the center O2 is offset backward relative to the third axis O1, the portion with greater interference between the cleaning belt 24 and the first conveying section 1152 can be positioned closer to the upper end of the first conveying section 1152. Furthermore, if the center O2 is offset forward relative to the third axis O1, the portion with greater interference between the cleaning belt 24 and the first conveying section 1152 can be positioned closer to the lower end of the first conveying section 1152. The distance Q can be used to adjust the distribution of interference between the cleaning belt 24 and the first conveying section 1152.

[0164] See also Figure 13 , Figure 13 for Figure 12 The cleaning module 20, the conveying portion 115 and the introduction portion 116 are shown in the following diagrams: Figure 13 shown.

[0165] A first reference line CK1 and a second reference line CK2 are defined on a reference cross 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. The angle c between the first reference line CK1 and the second reference line CK2 is between 50° and 85°. The size of the angle c determines the length of the first conveying section 1152, which necessitates limiting the angle c to minimize excessive length of the first conveying section 1152, reduce redundancy, and minimize the impact of an excessively long first conveying section 1152 on the cleaning performance of the cleaning body 103. The angle c can be used to rationally adjust the length of the first conveying section 1152 so that it preferentially matches the second roller 22.

[0166] 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.

[0167] See also Figure 10 On a reference cross section perpendicular to the support plane PL, a line connecting a point on the first conveying section 1152 and the lower end of the conveying slope 1151 forms a first angle a1 with the reference plane PL1, and the first angle a1 ranges from 48.6 to 52.5 degrees. The reference plane PL1 is arranged parallel to the support plane PL. The maximum value of the first angle a1 can be determined based on the upper end and / or lower end of the first conveying section 1152. Furthermore, the maximum value of the first angle a1 can be the angle between the conveying slope 1151 and the support plane PL, or the angle between other conveying sections on the conveying slope 1151 and the support plane PL. The minimum value of the first angle a1 determines the degree of concavity of the first conveying section 1152, and the span of the first angle a1 between the minimum and maximum values ​​determines the form of the concavity of the first conveying section 1152. In some embodiments, the first angle a1 is 49°, 49.5°, 50°, 50.5°, 51°, 51.5°, or 52°.

[0168] See also Figure 10 On a reference cross section perpendicular to the support plane PL, a line connecting the upper and lower ends of the conveying inclined surface 1151 forms a second angle a2 with the reference plane PL1. The difference between the second angle a2 and the first angle a1 is between 4 and 13 degrees. In some embodiments, the difference between the second angle a2 and the first angle a1 is 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, 11 degrees, 12 degrees, or 13 degrees.

[0169] In some embodiments, the smaller the difference between the second angle a2 and the first angle a1, the smoother the conveying slope. The difference between the second angle a2 and the first angle a1 can be used to adjust the interference distribution between the cleaning belt 24 and the conveying slope 1151, reduce the gap between the cleaning belt 24 and the conveying slope 1151, and improve the cleaning effect of the cleaning body 103.

[0170] See also Figure 10 On a reference cross section perpendicular to the support plane PL, the ratio of the chord length of the first conveying section 1152 to the upper and lower lengths of the conveying inclined surface 1151 is between 0.3 and 0.6. This ratio determines the size and maximum concavity of the first conveying section 1152, thereby adjusting the length of the cleaning body 103 in the front-to-back direction.

[0171] In some embodiments, on a reference section perpendicular to the support plane PL, the ratio of the chord length of the first conveying segment 1152 to the lengths of the upper and lower ends of the conveying slope 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.

[0172] In some embodiments, the chord length of the first transmission segment 1152 on a reference cross section perpendicular to the support plane PL is between 8 and 12 mm. In some embodiments, the chord length of the first transmission segment 1152 on a reference cross section perpendicular to the support plane PL is between 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, or 11.5 mm, etc.

[0173] See also Figure 10 On a reference cross section perpendicular to the support plane PL, the conveying slope 1151 may further include a second conveying section 1153, the lower end of which 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 slope 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 slope 1151.

[0174] In some embodiments, the second conveying section 1153 may be recessed on a side away from the cleaning belt 24 on a reference cross section perpendicular to the support plane PL to reduce interference between the second conveying section 1153 and the cleaning belt 24. This also allows the cleaning module 20 to be supported as much as possible by the surface to be cleaned during operation, thereby improving the cleaning performance of the cleaning body 103. In some embodiments, the second conveying section 1153 may be curved on a reference cross section perpendicular to the support plane PL to improve waste conveying efficiency.

[0175] In some embodiments, on a reference section perpendicular to the supporting plane PL, the curvature radius of the second conveying section 1153 is greater than the curvature radius of the first conveying section 1152 to control the degree of interference between the second conveying section 1153 and the cleaning belt 24 .

[0176] In some embodiments, the second conveying section 1153 may be a plane on a reference cross section perpendicular to the support plane PL. The upper end and / or lower end of the first conveying section 1152 may be located on an extension of the second conveying section 1153. In some embodiments, the second conveying section 1153 may be a plane on a reference cross section perpendicular to the support plane PL. The upper end and / or lower end of the first conveying section 1152 may be located on a side of the extension of the second conveying section 1153 that faces away from the second roller 22, thereby further reducing the length of the cleaning body 103 in the front-to-back direction, allowing the cleaning body 103 to be miniaturized and making it easier for the user to operate the cleaning device 101.

[0177] In some embodiments, the upper end of the first conveying section 1152 and the lower end of the second conveying section 1153 can be connected by a smooth transition, or can be connected through other conveying sections.

[0178] See also Figure 14 , Figure 14 for Figure 8 The cleaning module 20, the conveying portion 115 and the introduction portion 116 are shown in the following diagrams: Figure 14 shown.

[0179] The conveying slope 1151 may have a first slope section 1156 and a second slope section 1157 connected thereto. The second slope section 1157 may be closer to the upper end of the conveying slope 1151 than the first slope section 1156. The first slope section 1156 may be closer to the lower end of the conveying slope 1151 than the second slope section 1157.

[0180] In some embodiments, the lower end of the first slope section 1156 may be the lower end of the conveying slope 1151 , and the upper end of the second slope section 1157 may be the upper end of the conveying slope 1151 .

[0181] In some embodiments, the first inclined surface section 1156 can be provided as the first conveying section 1152 in the above-described embodiment. In some embodiments, the first inclined surface section 1156 can be the first conveying section 1152 in the above-described embodiment. In some embodiments, the second inclined surface section 1157 can be provided as the second conveying section 1153 in the above-described embodiment. In some embodiments, the second inclined surface section 1157 can be the second conveying section 1153 in the above-described embodiment.

[0182] See also Figure 15 , Figure 15 for Figure 14 The structure diagram of the transmission part 115 in the embodiment shown is as follows. The transmission part 115 is shown on a reference cross section perpendicular to the support plane PL. Figure 15 shown.

[0183] On a reference cross section perpendicular to support plane PL, a line connecting the upper and lower ends of first sloped surface segment 1156 forms a first angle b1 with reference plane PL2. A line connecting the upper and lower ends of second sloped surface segment 1157 forms a second angle b2 with reference plane PL1. A line 1158 connecting the lower end of first sloped surface segment 1156 and the upper end of second sloped surface segment 1157 forms a third angle b3 with reference plane PL1. The first angle b1 is smaller than the third angle b3, and the third angle b3 is smaller than the second angle b2. Reference plane PL2 is parallel to support plane PL.

[0184] exist Figure 14 The first slope segment 1156 can be set based on the first included angle b1, and the first slope segment 1156 can replace the second slope segment 1157, and the first slope segment 1156 can be implemented. Figure 6In the cleaning body 103, the conveying slope 1151 cooperates with the cleaning module 20, such as the cleaning belt 24, to transport garbage to the drop port 1004. The force at the contact point between the conveying slope 1151 and the cleaning module 20 decreases, and the cleaning module 20 is supported as much as possible by the surface to be cleaned in the working mode. However, this also increases the gap between the upper portion of the conveying slope 1151 and the cleaning module 20, such as the cleaning belt 24. Consequently, when the upper portion of the conveying slope 1151 cooperates with the cleaning module 20, such as the cleaning belt 24, garbage cannot be transported even if the gap is smaller than the gap. Furthermore, the second slope section 1157 cooperates with the cleaning module 20, such as the cleaning belt 24, to improve the garbage transport capability.

[0185] Figure 15 The first inclined surface section 1156 is set based on the first angle b1, and the second inclined surface section 1157 is set based on the second angle b2, so that the force at the contact part between the conveying inclined surface 1151 and the cleaning module 20 can be reduced, and the cleaning module 20 can be supported by the surface to be cleaned as much as possible in the working mode. At the same time, the second inclined surface section 1157 is also used to reduce the gap between the upper part of the conveying inclined surface 1151 and the cleaning module 20, such as the cleaning belt 24, so that the upper part of the conveying inclined surface 1151 and the cleaning module 20, such as the cleaning belt 24, can cooperate to realize the transportation of smaller garbage.

[0186] In some embodiments, see Figure 15 , the difference between the second angle b2 and the first angle b1 is between 1-10 degrees. In working mode, in order to reduce the force between the surface to be cleaned and the supporting cleaning module 20 caused by the second inclined surface section 1157 supporting the cleaning module 20, it is necessary to limit the second angle b2. In addition, the selection of garbage size can also be achieved by adjusting the difference, and garbage of a preset target size can be cleaned. In some embodiments, the difference between the second angle b2 and the first 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.

[0187] In some embodiments, see Figure 15 The first angle b1 is between 48 and 54 degrees, which can improve the fit between the first sloped surface section 1156 and the cleaning module 20 in the working mode and can also adjust the support effect of the first angle b1 on the cleaning module 20. In some embodiments, the first angle b1 is 48.5°, 49°, 49.5°, 50°, 50.5°, 51°, 51.5°, 52°, 52.5°, 53.5°, or 53°.

[0188] In some embodiments, the length ratio of the line connecting the upper and lower ends of the first slanted section 1156 to the line connecting the upper and lower ends of the second slanted section 1157 is between 0.5 and 1.5. By adjusting the length ratio, the second angle b2 can be adjusted, thereby adjusting the cooperation between the second slanted section 1157 and the cleaning module 20, such as the cleaning belt 24, to achieve the conveyance of smaller garbage. In addition, by adjusting the length ratio, the cleaning body 103 can be miniaturized, making it easier for users to operate the cleaning device 101. In some embodiments, the length ratio of the line connecting the upper and lower ends of the first slanted section 1156 to the line connecting the upper and lower ends of the second slanted section 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.

[0189] See also Figure 15 Since the upper end of the first inclined surface section 1156 is connected to the lower end of the second inclined surface section 1157, in order to ensure that the cleaning belt 24 is in effective contact with the conveying inclined surface 1151 and realize garbage transportation, the cleaning belt 24 can be in contact with the lower end of the first inclined surface section 1156 and the upper end of the second inclined surface section 1157, and 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 section 1156 and the upper end of the second inclined surface section 1157. The upper end of the first inclined surface section 1156 and the lower end of the second inclined surface section 1157 must be the farthest part from the base layer 241, and the fluff layer 242 needs to be in contact with the upper end of the first inclined surface section 1156 and the lower end of the second inclined surface section 1157. The ratio of the vertical distance from the upper end of the first inclined surface section 1156 or the lower end of the second inclined surface section 1157 to the connecting line 1158 to the fluff length of the fluff layer 242 is between 0.7 and 0.9. By adjusting the ratio, the conveying inclined surface 1151 can be effectively contacted with the cleaning belt 24.

[0190] In some embodiments, to ensure effective contact between the cleaning belt 24 and the conveying inclined surface 1151 and to achieve garbage conveying, the cleaning belt 24 can be brought into contact with the lower end of the first inclined surface section 1156 and the upper end of the second inclined surface section 1157. Furthermore, between the lower end of the first inclined surface section 1156 and the upper end of the second inclined surface section 1157, the ratio of the change in the interference amount of the conveying inclined surface 1151 on the fluff layer 242 (the difference between the maximum interference amount and the minimum interference amount of the conveying inclined surface 1151 on the fluff layer 242) to the maximum interference amount (the maximum interference amount of the conveying inclined surface 1151 on the fluff layer 242) is between 0.2 and 0.7. By adjusting the ratio, the conveying inclined surface 1151 and the cleaning belt 24 can be effectively contacted, and the cleaning ability can also be improved by adjusting the ratio. In some embodiments, the measurement of the maximum interference amount and the minimum interference amount of the conveying inclined surface 1151 on the fluff layer 242 must be performed in the same state among the first state, the second state, and the third state. In some embodiments, the measurement of the maximum interference amount and the minimum interference amount of the conveying inclined surface 1151 on the fluff layer 242 must be performed in the second state.

[0191] See also Figure 14 The first roller 21 and the second roller 22 have a common section PM on the side near the conveying inclined surface 1151. The common section PM forms a fourth angle b4 with the reference plane PL3. The reference plane PL3 is arranged parallel to the support plane PL. When the cleaning belt 24 is pressed against the surface to be cleaned by the second roller 22, the fourth angle b4 is less than the second angle b2 and greater than the first angle b1. This allows effective contact between the second inclined surface segment 1157 and the cleaning belt 24, thereby improving cleaning performance. It also reduces the pressure of the cleaning module 20 on the first inclined surface segment 1156, allowing the cleaning module 20 to be supported by the surface to be cleaned as much as possible.

[0192] In some embodiments, when the second roller 22 is suspended, the second roller 22 can be in a suspended state, and the second roller 22 can press the cleaning belt 24 against the conveying inclined surface 1151, so that the cleaning body 103 can perform self-cleaning mode. The fourth angle b4 is greater than the second angle b2, which can increase the force between the conveying inclined surface 1151 and the cleaning module 20 to perform self-cleaning and ensure the self-cleaning effect.

[0193] In some embodiments, the absolute value of the difference between the second angle b2 and the first angle b1 and the difference between the angular change of the fourth angle b4 when the second roller 22 is suspended and when the cleaning belt 24 is pressed against the surface to be cleaned by the second roller 22 is between 1 and 7 degrees, so as to ensure effective contact between the conveying inclined surface 1151 and the cleaning belt 24. In some embodiments, the absolute value of the difference between the second angle b2 and the first angle b1 and the difference between the angular change of the fourth angle b4 when the second roller 22 is suspended and when the cleaning belt 24 is pressed against the surface to be cleaned by the second roller 22 is 1.5 degrees, 2 degrees, 2.5 degrees, 3 degrees, 3.5 degrees, 4 degrees, 4.5 degrees, 5 degrees, 5.5 degrees, 6 degrees, or 6.5 degrees, etc. It is understood that when the second roller 22 is suspended, the second roller 22 can be in a suspended state.

[0194] In some embodiments, the first bevel segment 1156 and the second bevel segment 1157 can be connected by a smooth transition or by passing through another bevel segment. In some embodiments, the first bevel segment 1156 and the second bevel segment 1157 are connected by an arc-shaped transition.

[0195] See also Figure 1 and Figure 16 , Figure 16 for Figure 1 The cleaning system 100 is shown in a cross-sectional view taken along line XV-XV in the embodiment shown. A supporting surface 1021 is provided on the base station 102, and the supporting surface 1021 can be used to support the cleaning body 103. When the cleaning body 103 is placed on the base station 102, it can be placed on the supporting surface 1021.

[0196] See also Figure 16 When the cleaning body 103 is placed on the supporting surface 1021, the cleaning module 20 can remain suspended, and the cleaning body 103 can activate the self-cleaning mode, causing the second roller 22 to rotate, 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, so that part of the cleaning module 20 is located below the supporting plane PL, and then the self-cleaning mode can be activated, causing the second roller 22 to rotate, further driving the cleaning belt 24 to rotate.

[0197] It is understandable that (1) in working mode, Figure 16 In the example, the cleaning body 103 is placed not on the support surface 2001 but on the surface to be cleaned. The cleaning module 20 contacts the surface to be cleaned, and the connecting rod assembly 23 drives the second roller 22 and the cleaning belt 24 to swing away from the conveyor ramp 1151, so that the cleaning module 20 is positioned on the support plane PL. In this case, because the surface to be cleaned shares at least part of the weight of the cleaning module 20, the contact between the cleaning belt 24 and the conveyor ramp 1151 is less effective than in the self-cleaning mode.

[0198] (2) In self-cleaning mode, Figure 16 The cleaning body 103 is placed on the carrying surface 2001 and contacts the carrying surface 2001. The cleaning module 20 contacts the carrying surface 2001. The connecting rod assembly 23 can drive the second roller 22 and the cleaning belt 24 to swing. On the basis of the above (1), it can further swing toward the direction close to the conveying inclined surface 1151, so that part of the cleaning module 20 is located below the supporting plane PL. At this time, the force between the carrying surface 2001 and the cleaning module 20 is smaller than the 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 surface 1151 at this time is better than the contact effect in the above (1). Then, the self-cleaning mode can be further activated. 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.

[0199] (3) In self-cleaning mode, Figure 16 The cleaning body 103 is placed on the carrying surface 2001 and contacts the carrying surface 2001. The cleaning module 20 is spaced apart from the carrying surface 2001. The connecting rod assembly 23 can drive the second roller 22 and the cleaning belt 24 to swing. On the basis of the above (2), it can further swing toward the direction close to the conveying inclined surface 1151, so that part of the cleaning module 20 is located below the supporting plane PL. At this time, the force between the carrying surface 2001 and the cleaning module 20 is 0. The contact effect between the cleaning belt 24 and the conveying inclined surface 1151 at this time is better than the contact effect of the above (1) and (2). Then, the self-cleaning mode can be further activated to improve the cleaning efficiency in the self-cleaning mode and improve the removal rate of the accumulated garbage of the cleaning device 101.

[0200] See also Figure 16 A receiving groove 1022 is provided on the base station 102. When the cleaning body 103 is supported on the supporting surface 1021, the projection of the second roller 22 along the direction of gravity at least partially falls into the receiving groove 1022, and the cleaning belt 24 wrapped around the second roller 22 extends into the receiving groove 1022 and is spaced apart from the groove wall of the receiving groove 1022.

[0201] In some embodiments, the receiving groove 1022 can be provided on the bearing surface 1021, extending below the support plane PL so as to be spaced apart from the cleaning belt 24 wrapped around the second roller 22. In some embodiments, the receiving groove 1022 can be omitted, and the cleaning module 20, such as the second roller 22 and the cleaning belt 24, can be kept suspended in other ways. In some embodiments, the cleaning belt 24 wrapped 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 wrapped 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 wrapped 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 garbage dropped from the cleaning belt 24 and can also receive garbage sliding down the conveying inclined surface 1511.

[0202] Optionally, by keeping the cleaning module 20 in a suspended state and spaced apart from the wall of the receiving groove 1022, the cleaning belt 24 does not contact the wall of the receiving groove 1022. At this time, when the cleaning belt 24 rotates along the first direction, it will not form a friction force with the wall of the receiving groove 1022 away from the conveying inclined surface 1151, and thus will not have a torque away from the conveying inclined surface 1151, thereby ensuring the pressure of the cleaning module 20 on the conveying inclined surface 1151 and effectively improving the cleaning force.

[0203] In some embodiments, Figure 16 The cleaning body 103 is placed on the carrying surface 1021, and the cleaning belt 24 wrapped 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. Figure 6 The middle cleaning body 103 is placed on the surface to be cleaned and supported by the surface to be cleaned. Figure 16 The cleaning module 20 in a suspended state can be swung by the connecting rod assembly 23. The 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 introduction part 116 and / or the conveying inclined surface 1151, so that the supporting force of the introduction part 116 and / or the conveying inclined surface 1151 on the cleaning module 20 becomes larger, and the distance between the cleaning belt 24 and the introduction part 116 and / or the conveying inclined surface 1151 is reduced, so as to facilitate the cleaning of garbage on the introduction part 116 and / or the conveying inclined surface 1151 in the self-cleaning mode.

[0204] The base station 102 is provided with a guide slope 1023 on one edge thereof, which is connected to the supporting surface 1021. The guide slope 1023 allows the supporting surface 1021 to be aligned with the surface to be cleaned or the ground, so that the cleaning body 103 can be rolled from the surface to be cleaned or the ground onto the guide slope 1023 and further onto the supporting surface 1021 under the rolling of the wheel body 13, thereby placing the cleaning body 103. In some embodiments, the guide slope 1023 can be omitted.

[0205] The base station 102 is provided with a limiting mechanism 1024. When the cleaning body 103 is placed on the base station 102, the limiting mechanism 1024 cooperates with the cleaning body 103 to limit the position of the cleaning body 103. This can keep the cleaning body 103 stable and prevent shaking when the cleaning body 103 activates the self-cleaning mode, thereby ensuring the safe use of the cleaning body 103. In some embodiments, the limiting mechanism 1024 can be provided on the supporting surface 1021.

[0206] In some embodiments, the limiting mechanism 1024 may be one or more of a groove, a bump, or a baffle. In some embodiments, the limiting mechanism 1024 may be a limiting groove to accommodate the wheel body 13, thereby limiting the position of the wheel body 13 and further limiting the position of the cleaning body 103. In some embodiments, the limiting mechanism 1024 may include a first limiting groove 1025 and a second limiting groove 1026. The first limiting groove 1025 may be provided corresponding to the front wheel body 131, and the second limiting groove 1026 may be provided corresponding to the rear wheel body 132. When the cleaning body 103 is placed on the base station 102, the front wheel body 131 is located in the first limiting groove 1025, and the rear wheel body 132 is located in the second limiting groove 1026. In some embodiments, one of the first limiting groove 1025 and the second limiting groove 1026 may be omitted. In some embodiments, on a reference cross 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 configured in an arc shape that matches the outer circumference of the front wheel body 131. This can better limit the position of the front wheel body 131, reduce the shaking of the cleaning body 103, and facilitate the front wheel body 131 to slide out of the first limiting groove 1025 when the user manipulates the cleaning body 103. In some embodiments, on a reference cross 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 configured in an arc shape that matches the outer circumference of the rear wheel body 132. This can better limit the position of the rear wheel body 132, reduce the shaking of the cleaning body 103, and facilitate the rear wheel body 132 to slide out of the second limiting groove 1026 when the user manipulates the cleaning body 103.

[0207] In some embodiments, the first limiting groove 1025 is disposed adjacent to the receiving groove 1022, and the first limiting groove 1025 is recessed less deeply than the receiving groove 1022. In some embodiments, the receiving groove 1022 may be formed at the bottom of the first limiting groove 1025, thereby directing trash within the first limiting groove 1025 toward 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.

[0208] The base station 102 may be provided with a limiting protrusion 1027. When the cleaning body 103 is placed on the base station 102, the limiting protrusion 1027 cooperates with the cleaning body 103 to limit the position of the cleaning body 103. This helps keep the cleaning body 103 stable and prevents shaking when the cleaning body 103 activates the self-cleaning mode, thereby ensuring safe use of the cleaning body 103. In some embodiments, the limiting protrusion 1027 may be part of the limiting mechanism 1024. In some embodiments, the limiting protrusion 1027 may correspond to the retaining slot 1111, so that when the cleaning body 103 is placed on the base station 102, the limiting protrusion 1027 is located within the retaining slot 1111. In some embodiments, the positioning of the limiting protrusion 1027 and the retaining slot 1111 may be interchangeable, and the retaining slot 1111 may also be part of the limiting mechanism 1024. In some embodiments, the limiting protrusion 1027 may be omitted. In some embodiments, the limiting protrusion 1027 may be provided on the supporting surface 1021.

[0209] In some embodiments, the limiting protrusion 1027 may be located between the first limiting groove 1025 and the second limiting groove 1026 .

[0210] In some embodiments, under the control of the user, the handle 104 can keep the front wheel body 131 suspended in the air, while the rear wheel body 132 slides, and the cleaning body 103 is pushed onto the supporting surface 1021 along the guiding inclined surface 1023 by the rear wheel body 132. When the rear wheel body 132 moves to a position limited by the limiting mechanism 1024 and the front wheel body 131 contacts the supporting surface 1021, the limiting protrusion 1027 extends into the locking groove 1111. Of course, the method of placing the cleaning body 103 on the supporting surface 1021 is not limited to this, and other methods can also be used, which will not be described in detail.

[0211] See also Figure 17 , Figure 17 for Figure 16 The base station 102 is a schematic structural diagram of the embodiment shown.

The fan 60 can provide a circulating airflow for the cleaning body 103, and of course can also provide a drying airflow or an airflow with a disinfectant according to the needs of technical personnel in this field. The airflow can be generated by the fan 60 in the self-cleaning mode, and can be blown toward the cleaning belt 24 to accelerate the drying and / or disinfection of the cleaning belt 24. In some embodiments, the airflow can be guided into the storage groove 1022 by the supporting base 50, and blow the cleaning belt 24 extending into the storage groove 1022. In some embodiments, the fan 60 can operate in the self-cleaning mode. In some embodiments, the fan 60 can be omitted.

[0212] The support base 50 includes a main housing 51 and a tray 52 detachably mounted on the main housing 51. The main housing 51 and the tray 52 can cooperate to support the base station 102. Alternatively, the main housing 51 alone can support the base station 102. In some embodiments, the tray 52 can be omitted. In some embodiments, the main housing 51 and the tray 52 can be integrally formed.

[0213] The main housing 51 may include a support portion 511 and sidewall portions (e.g., a first sidewall portion 512, a second sidewall portion 513, and a third sidewall portion 514). The support portion 511 may be provided with a bearing surface 1021 to support the cleaning body 103. The sidewall portions may be disposed around the support portion 511 to define a space within which the cleaning body 103 is placed and to limit airflow. In some embodiments, the sidewall portions, such as the first sidewall portion 512, the second sidewall portion 513, and the third sidewall portion 514, may be omitted.

[0214] The edge of one side of the support portion 511 is provided with a guide slope 1023 connected to the bearing surface 1021, and the bearing surface 1021 can be matched with the surface to be cleaned or the ground through the guide slope 1023, so that the cleaning body 103 can roll from the surface to be cleaned or the ground to the guide slope 1023 under the rolling of the wheel body 13, and further roll to the bearing surface 1021, so as to realize the placement of the cleaning body 103.

In some embodiments, at least one of the first sidewall portion 512, the third sidewall portion 514, and the second sidewall portion 513 is an integral structure with the support portion 511.

[0217] The first side wall portion 512 and the second side wall portion 513 are disposed on opposite sides of the support portion 511, and the third side wall portion 514 and the guide slope 1023 are disposed between the first side wall portion 512 and the second side wall portion 513. The guide slope 1023 is disposed on one side of the support portion 511, such that the third side wall portion 514 is disposed on a side of the support portion 511 away from the guide slope 1023.

[0218] In some embodiments, when the cleaning body 103 is placed on the base station 102, the first side wall portion 512 is located on a side of the cleaning body 103 where the second side wall 114 is provided, and is disposed opposite to the second side wall 114.

Of course, the cleaning device 101 and the base station 102 may also interact, and further, the cleaning device 101, such as the cleaning body 103, may be upgraded or repaired. Of course, the second electrical connection end 5131 may also be selectively provided at other locations of the base station 102, such as the supporting base 50, according to the needs of those skilled in the art.

[0220] In some embodiments, when the cleaning body 103 is placed on the base station 102, the second electrical connection end 5131 and the first electrical connection end 1131 can be automatically electrically connected. In some embodiments, when the cleaning body 103 and the limiting mechanism 1024 are cooperated to be limited on the base station 102, the second electrical connection end 5131 and the first electrical connection end 1131 can be automatically electrically connected.

[0221] In some embodiments, the cleaning device 101 can control the fan 60 through the first electrical connection terminal 1131 and the second electrical connection terminal 5131 .
