[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-Figure 3 As shown, the embodiment of the utility model provides a cleaning device 100, including a chassis 10, a cleaning member 20 and an anti-winding member 30. The cleaning member 20 is mounted on the chassis 10, and the cleaning member 20 can rotate relative to the surface to be cleaned, so as to clean the surface to be cleaned. The anti-winding member 30 is rotatably mounted on the chassis 10 and interferes with the cleaning member 20. The anti-winding member 30 is used to interfere with the long strips of garbage on the cleaning member 20 and rotate when the cleaning member 20 rotates, so as to collect the long strips of garbage on the cleaning member 20.

[0035] In an optional embodiment, the cleaning component 20 may include a fixed bracket, and a rolling brush or an annular belt, etc., which are arranged on the bracket, or other cleaning components available on the market.

[0036] The cleaning device 100 proposed in the embodiment of the utility model can collect the long strips of garbage such as hair and floccules on the cleaning member 20 through the setting of the anti-winding member 30, and the anti-winding member 30 can be turned around to help wind the long strips of garbage such as hair around the anti-winding member 30, thereby preventing the cleaning member 20 from being entangled by the hair and getting stuck, thereby affecting the cleaning effect. At the same time, when the cleaning member 20 rotates and interferes with the anti-winding member 30, the anti-winding member 30 can rotate with it, thereby winding up the long strips of garbage on the cleaning member 20, thereby realizing the collection of the long strips of garbage.

[0037] Optionally, when the anti-winding member 30 and the cleaning member 20 rotate, they interfere with the cleaning member 20 and rotate along with it, which can also reduce the interference with the rotation of the cleaning member 20.

[0038] Exemplarily, both axial ends of the anti-winding member 30 can be rotatably connected to the chassis 10 . Of course, a rotating shaft can also be provided on the chassis 10 , and the anti-winding member 30 can be directly rotatably sleeved on the rotating shaft to achieve rotational connection to the chassis 10 .

[0039] In some embodiments, the anti-winding member 30 is configured to rotate under the drive of the cleaning member 20 when the cleaning member 20 rotates and interferes with the cleaning member 20. In this embodiment, the anti-winding member 30 and the chassis 10 are rotatably arranged, and the movement of the cleaning member 20 can drive the anti-winding member 30 to rotate, thereby facilitating the winding of long strips of garbage such as hair and floccules on the anti-winding member 30, so as to collect the long strips of garbage on the cleaning member 20, thereby preventing the cleaning member 20 from getting stuck and affecting the cleaning effect.

[0040] Of course, the anti-winding member 30 can also be actively rotated when needed. For example, in other embodiments, the anti-winding member 30 is used to be connected to a driving device, so that when the cleaning member 20 rotates and interferes with the cleaning member 20, the anti-winding member 30 is driven to rotate by the driving device. In this embodiment, the driving device can be a motor, and the motor provides a driving force to drive the anti-winding member 30 to actively rotate, so that the hair, floccules and other long strips of garbage on the cleaning member 20 are wound around the anti-winding member 30, so as to collect the long strips of garbage on the cleaning member 20, thereby preventing the cleaning member 20 from getting stuck and affecting the cleaning effect.

[0041] In some embodiments, Figure 5As shown, the anti-winding member 30 may include a mounting member 31 and a first hooking member 32 which are separately arranged, and the mounting member 31 is mounted on the chassis 10 and close to the cleaning member 20. The first hooking member 32 is arranged on the outer wall of the mounting member 31, and the first hooking member 32 is installed by the mounting member 31. The first hooking member 32 is used to interfere with the long strips of garbage on the cleaning member 20 when the cleaning member 20 rotates, and rotates relative to the mounting member 31 or rotates simultaneously with the mounting member 31, so that the long strips of garbage on the cleaning member 20 can be wound around the first hooking member 32. Exemplarily, the mounting member 31 can be fixedly mounted on the chassis 10, and the first hook member 32 is configured to be rotatable relative to the mounting member 31, so that the long strips of garbage on the cleaning component 20 can be wound around the first hook member 32. Of course, the mounting member 31 can also be rotatably connected to the chassis 10, and the first hook member 32 is fixedly mounted on the mounting member 31. At this time, the first hook member 32 can rotate synchronously with the mounting member 31, and the long strips of garbage on the cleaning component 20 can also be wound around the first hook member 32.

[0042] It should be noted that the fixed installation may be a detachable fixed installation or a non-detachable fixed installation.

[0043] In some embodiments, the first hooking member 32 is detachably mounted on the mounting member 31. In this embodiment, the first hooking member 32 is detachably mounted, so that after the long strips of garbage such as hair and floccules on the cleaning member 20 are entangled with the first hooking member 32, only the first hooking member 32 can be disassembled without disassembling the mounting member 31, thereby simplifying the disassembly and assembly steps, realizing the reuse of the mounting member 31, and saving costs. The first hooking member 32 can be directly recycled to facilitate the replacement of a new first hooking member 32, or it can be reused after cleaning the garbage.

[0044] As an embodiment, the first hook member 32 can be tightly mounted on the outer peripheral wall of the mounting member 31 so that no relative movement occurs between the first hook member 32 and the mounting member 31. At this time, the mounting member 31 is rotationally connected to the chassis, and when interference occurs with the cleaning component 20, the first hook member 32 and the mounting member 31 rotate together.

[0045] As another embodiment, the first hooking member 32 can be movably mounted on the outer peripheral wall of the mounting member 31, so that the first hooking member 32 and the mounting member 31 can rotate relative to each other. At this time, the mounting member 31 is fixedly installed on the chassis, and the first hooking member 32 rotates relative to the mounting member 31 when interference occurs with the cleaning component 20.

[0046] In some embodiments, Figure 6As shown, the first hooking member 32 includes a hook surface 321 capable of hooking long strips of garbage, and the hook surface 321 is provided with a plurality of first hook-shaped protrusions 3211. In this embodiment, the first hooking member 32 can be a Velcro with a hook surface 321, which has a simple structure, is convenient for disassembly and assembly, and reduces the use cost. The plurality of first hook-shaped protrusions 3211 make it have strong adhesion to the long strips of garbage such as hair, so that the hair can be easily adhered to the first hooking member 32, and then the hair can be firmly wrapped around the first hooking member 32 by rotation. The mounting member 31 can be a rod-shaped structure, so that the first hooking member 32 is conveniently sleeved on the mounting member 31, and the hook surface 321 of the Velcro is arranged outward, and the long strips of garbage such as hair and floccules on the cleaning member 20 are hooked by the plurality of first hook-shaped protrusions 3211 on the hook surface 321, and the long strips of garbage such as hair and floccules can be wrapped around the first hooking member 32 by the rotation of the first hooking member 32, so as to collect the long strips of garbage on the cleaning member 20.

[0047] In some embodiments, the first hooking member 32 extends along the width direction of the surface of the cleaning member 20, and the extension length of the first hooking member 32 is consistent with the width of the surface of the cleaning member 20. In this embodiment, the extension length of the first hooking member 32 is set to be consistent with the width of the surface of the cleaning member 20, so that the entire width area of ​​the surface of the cleaning member 20 can be covered by the first hooking member 32, so that it is convenient to collect the long strips of garbage on the entire surface of the cleaning member 20, thereby achieving a better anti-entanglement effect on the cleaning member 20.

[0048] It should be noted that the anti-winding member 30 is not limited to the installation member 31 and the first hooking member 32. For example, in other embodiments, Figure 7 and Figure 8 As shown, the anti-winding member 30 may also adopt a second hooking member 33, which is rotatably mounted on the chassis 10 and close to the cleaning member 20. The second hooking member 33 is used to interfere with the long strips of garbage on the cleaning member 20 and rotate when the cleaning member 20 rotates, so that the long strips of garbage on the cleaning member 20 can be wound around the second hooking member 33. In this embodiment, the second hooking member 33 can also be directly used to achieve installation and collect the long strips of garbage, simplifying the number of components and making the anti-winding member 30 structure simpler. Exemplarily, the long strips of garbage can be hooked by the second hooking member 33, and through the rotatable setting of the second hooking member 33, when the cleaning member 20 rotates and interferes with the second hooking member 33, it can rotate with it, thereby facilitating the winding of the long strips of garbage around the second hooking member 33 and avoiding affecting the rotation of the cleaning member 20.

[0049] In some embodiments, the second hook member 33 is detachably connected to the chassis 10, so that the second hook member 33 can be easily disassembled to clean up garbage, thereby facilitating the reuse of the second hook member 33 and saving usage costs.

[0050] In some embodiments, Figure 4 , Figure 7 and Figure 8 As shown, the cleaning device 100 further includes a cleaning auxiliary member 40, which is configured to be movably mounted on the second hook member 33 or to be separated from the second hook member 33. When the cleaning auxiliary member 40 moves along the first direction on the second hook member 33, it interferes with the long strips of garbage wound on the second hook member 33, thereby separating the long strips of garbage from the second hook member 33. The first direction is the length direction of the second hook member 33. In this embodiment, after the second hook member 33 is removed from the chassis 10, the cleaning auxiliary member 40 can cooperate with the second hook member 33 to separate the long strips of garbage such as hair for processing, so that the cleaned second hook member 33 can be installed on the chassis 10 again, so that the second hook member 33 can be reused, thereby saving costs.

[0051] In some embodiments, Figure 7 and Figure 8 As shown, the second hooking member 33 includes a body 331 and a plurality of hook-shaped protrusion groups 332 protruding from the outer peripheral wall of the body 331. The plurality of hook-shaped protrusion groups 332 are arranged at intervals around the circumference of the body 331, and each hook-shaped protrusion group 332 includes a plurality of second hook-shaped protrusions 3321 arranged along the first direction. In this embodiment, the body 331 can be a cylindrical structure, and a plurality of hook-shaped protrusion groups 332 are arranged around the outer peripheral wall of the body 331 with the axis of the body 331 as the center, and each hook-shaped protrusion group 332 is provided with a plurality of second hook-shaped protrusions 3321 arranged in an arranged manner, so as to facilitate the hooking of the long strip of garbage on the cleaning member 20, and the long strip of garbage is wound around the second hooking member 33 during the rotation of the second hooking member 33.

[0052] In some embodiments, Figure 7-Figure 9As shown, the outer peripheral wall of the body 331 is concavely provided with a plurality of limiting grooves 333 along the circumferential direction, and the plurality of limiting grooves 333 are staggered with the plurality of hook-shaped protrusion groups 332. The cleaning auxiliary member 40 includes a limiting hole 41 for the second hooking member 33 to pass through, and a limiting protrusion 42 adapted to the limiting groove 333 is convexly provided on the inner wall of the limiting hole 41. The limiting protrusion 42 is used to insert into the limiting groove 333 when the cleaning auxiliary member 40 moves along the first direction on the second hooking member 33 to interfere with the long strip of garbage wrapped on the second hooking member 33, thereby separating the long strip of garbage from the second hooking member 33. In this embodiment, a plurality of limiting grooves 333 are arranged on the outer peripheral wall of the main body 331 with the axis of the main body 331 as the center and are arranged at intervals, and the limiting grooves 333 and the hook-shaped protrusion groups 332 are staggered so that any limiting groove 333 is located between two adjacent hook-shaped protrusion groups 332, thereby facilitating the insertion of the limiting protrusion 42 into the limiting groove 333 while avoiding interference between the limiting protrusion 42 and the second hook-shaped protrusion 3321. Through the cooperation between the limiting protrusion 42 and the limiting groove 333, the long strips of garbage wrapped around the second hook member 33 can be separated, thereby facilitating the reuse of the second hook member 33.

[0053] In some embodiments, the second hooking member 33 extends along the width direction of the surface of the cleaning member 20, and the extension length of the second hooking member 33 is consistent with the width of the surface of the cleaning member 20. In this embodiment, the extension length of the second hooking member 33 is set to be consistent with the width of the surface of the cleaning member 20, so that the entire width area of ​​the surface of the cleaning member 20 can be covered by the second hooking member 33, so that it is convenient to collect the long strips of garbage on the entire surface of the cleaning member 20, thereby achieving a better anti-entanglement effect on the cleaning member 20.

[0054] In some embodiments, Figure 1 As shown, the chassis 10 includes an upper cover 11 and a bottom shell 12, and the cleaning member 20 is rotatably mounted on the bottom shell 12 so that the cleaning member 20 can adjust the gap between the cleaning member 20 and the surface to be cleaned. The upper cover 11 is connected to the bottom shell 12 and is arranged on the side of the cleaning member 20 that is opposite to the surface to be cleaned. In this embodiment, the cleaning member 20 is rotatably mounted on the bottom shell 12, so that the cleaning member 20 can be lifted or reset, thereby adjusting the gap between the cleaning member 20 and the surface to be cleaned, and the garbage is transferred to the recovery container of the cleaning device 100 in the gap.

[0055] In some embodiments, the upper cover 11 is configured to rotate synchronously with the cleaning component 20 when the cleaning component 20 adjusts the gap between it and the surface to be cleaned. The setting of the upper cover 11 can protect the cleaning component 20 and can rotate synchronously when the cleaning component 20 rotates and adjusts, thereby preventing interference with the rotation of the cleaning component 20.

[0056] Optionally, the upper cover 11 can flexibly abut against the cleaning component 20, or abut against the cleaning component 20 under gravity, or be spaced apart from the cleaning component 20. When the cleaning component 20 rotates toward the upper cover 11, if it abuts against the upper cover 11, it can drive the upper cover 11 to rotate together.

[0057] It should be noted that the interference prevention here does not mean that there is no influence at all, but that within a certain rotation range, compared with the rigidly fixed upper cover, it will not affect the rotatable range of the cleaning component 20 (such as 20°). Depending on the specific situation, when the upper cover 11 is abutted when the cleaning component 20 rotates, the upper cover 11 will still apply a force to the cleaning component 20, which may reduce the rotation amplitude of the cleaning component 20. Of course, if the cleaning component 20 is rigidly rotated (such as it must rotate 5° or 15° due to external influences), then the upper cover 11 will have no effect on it.

[0058] Optionally, the upper cover 11 can be fixedly connected to the cleaning member 20, so as to rotate synchronously with the cleaning member 20 when the cleaning member 20 rotates, and can protect the cleaning member 20. Of course, in other embodiments, the upper cover 11 can also be rotatably connected to the bottom shell 12 through a rotating member, such as a rotating shaft.

[0059] Optionally, when the cleaning device 100 is cleaning garbage from the surface to be cleaned, the cleaning member 20 can automatically adjust the gap between the cleaning member 20 and the surface to be cleaned according to the size of the garbage, that is, the gap between the bottom of the cleaning member 20 and the surface to be cleaned can be automatically adjusted according to the size of the garbage. In a specific application, when the cleaning device 100 is moving on the surface to be cleaned to clean, if it encounters large garbage, the bottom of the cleaning member 20 can be lifted up, so that the large garbage can pass through the working area of ​​the cleaning member 20 and be transferred to the recovery container of the cleaning device by the cleaning member 20, thereby achieving the effect that the cleaning member 20 can automatically adjust the gap between the cleaning member 20 and the surface to be cleaned according to the size of the garbage, so that the cleaning device 100 can remove garbage of different sizes.

[0060] In some embodiments, the upper cover 11 is detachably connected to the bottom shell 12. In this embodiment, the upper cover 11 is detachably arranged to facilitate assembly and disassembly of the upper cover 11.

[0061] In some embodiments, Figure 1-Figure 2As shown, the anti-winding member 30 is installed on the side of the upper cover 11 facing the cleaning member 20. In this embodiment, since the upper cover 11 can keep synchronous rotation with the cleaning member 20 and is relatively close to the cleaning member 20, the anti-winding member 30 is installed on the upper cover 11, which can be more conducive to hooking the long strips of garbage on the cleaning member 20, and since the bottom shell 12 needs to be used to install other components such as recycling containers, the anti-winding member 30 is set on the upper cover 11, without occupying the installation space of the bottom shell 12, thereby increasing the installation space of the bottom shell 12 for other components.

[0062] In some embodiments, Figure 3 and Figure 4 As shown, the anti-winding member 30 is detachably connected to the upper cover 11. In this embodiment, the anti-winding member 30 is detachably arranged, and the anti-winding member 30 can be removed when the anti-winding member 30 needs to be cleaned or replaced, which is convenient for disassembly, cleaning or replacement.

[0063] In some embodiments, Figure 3 and Figure 4 As shown, the anti-winding member 30 includes a first end 30a and a second end 30b that are arranged oppositely, and the upper cover 11 includes a first side plate 111 and a second side plate 112 that are arranged oppositely. The first side plate 111 is provided with a first mounting structure 13 that is detachably connected to the first end 30a, and the second side plate 112 is provided with a second mounting structure 14 that is detachably connected to the second end 30b, so that the anti-winding member 30 can be detachably connected to the upper cover 11. In this embodiment, by setting the first mounting structure 13 and the second mounting structure 14, they cooperate with the first end 30a and the second end 30b of the anti-winding member 30, so as to realize the detachable mounting of the anti-winding member 30 on the upper cover 11.

[0064] In some embodiments, Figure 2-Figure 4As shown, the anti-winding member 30 also includes a limiting boss 34 provided at the first end 30a, the first mounting structure 13 includes a first mounting groove 131 adapted to the limiting boss 34, and the second mounting structure 14 includes a second mounting groove 141 adapted to the second end 30b, the first end 30a is inserted into the first mounting groove 131 through the limiting boss 34, and the second end 30b is inserted into the second mounting groove 141, so that the anti-winding member 30 can be detachably connected to the upper cover 11. In this embodiment, when installing, the second end 30b is first inserted into the second mounting groove 141, and then the limiting boss 34 of the first end 30a is snapped into the first mounting groove 131 to complete the installation of the anti-winding member 30. When disassembling, the limiting boss 34 of the first end 30a is first detached from the first mounting groove 131, and then the second end 30b is detached from the second mounting groove 141 to complete the disassembly of the anti-winding member 30. The anti-winding component 30 can be assembled and disassembled by the cooperation between the limiting boss 34 and the first installation groove 131 , and the cooperation between the second end 30 b and the second installation groove 141 .

[0065] In some embodiments, the outer diameter of the limiting boss 34 provided at the first end 30a is less than or equal to the inner diameter of the first mounting groove 131, and the outer diameter of the first end 30a is greater than the inner diameter of the first mounting groove 131. In this embodiment, through the above arrangement, the limiting boss 34 can be inserted into the first mounting groove 131, and the first end 30a is blocked outside the limiting groove 333, so that the limiting boss 34 can be firmly inserted into the first mounting groove 131, and the side of the second mounting groove 141 facing away from the second end 30b can be sealed. During installation, the second end 30b can be inserted into the second mounting groove 141 and can abut against the inner wall of the second mounting groove 141, and then the limiting boss 34 is inserted into the first mounting groove 131, which is convenient for installation.

[0066] In some embodiments, Figure 2-Figure 4 As shown, the first side plate 111 is provided with an open groove 113 connected to the first mounting groove 131. When the second end 30b is inserted into the second mounting groove 141, the open groove 113 is used to allow the limiting boss 34 to enter the first mounting groove 131 or to be separated from the first mounting groove 131. In this embodiment, through the provision of the open groove 113, it is convenient to insert the limiting boss 34 into the first mounting groove 131 from the radial direction through the open groove 113, so as to facilitate the disassembly and assembly of the anti-winding member 30.

[0067] Of course, in other embodiments, the opening groove 113 may not be provided, but the axial depth of the second mounting groove 141 may be deepened so that the second end 30b can be axially moved a certain distance after being inserted into the second mounting groove 141, so that the limiting boss 34 can be arranged relative to the first mounting groove 131, and then the second end 30b is moved in the direction opposite to the insertion direction without leaving the second mounting groove 141, so that the limiting boss 34 is inserted into the first mounting groove 131, thereby realizing the disassembly and assembly of the anti-winding component 30.

[0068] It should be noted that the anti-winding member 30 is not limited to only providing the limiting boss 34 at the first end 30a. For example, in other embodiments, the anti-winding member 30 also includes a first limiting boss provided at the first end 30a and a second limiting boss provided at the second end 30b. The first mounting structure 13 includes a first mounting groove 131 adapted to the first limiting boss, and the second mounting structure 14 includes a second mounting groove 141 adapted to the second limiting boss. The first end 30a is inserted into the first mounting groove 131 through the first limiting boss, and the second end 30b is inserted into the second mounting groove 141 through the second limiting boss, so that the anti-winding member 30 can be detachably connected to the upper cover 11. In this embodiment, the first limiting boss and the second limiting boss can be provided at the first end 30a and the second end 30b, respectively. During installation, the second limiting boss is first inserted into the second mounting groove 141, and then the first limiting boss is snapped into the first mounting groove 131 to complete the installation of the anti-winding member 30. During disassembly, the first limiting boss is first disengaged from the first mounting groove 131, and then the second limiting boss is disengaged from the second mounting groove 141 to complete the disassembly of the anti-winding member 30. The first limiting boss and the second limiting boss cooperate with the first mounting groove 131 and the second mounting groove 141 respectively to achieve the disassembly and assembly of the anti-winding member 30.

[0069] Of course, the anti-winding component 30 is not limited to the above-mentioned method of clamping the limiting boss and the installation groove to achieve disassembly and assembly. For example, in other examples, the anti-winding component 30 can also adopt other snap-fit ​​methods, or adopt threaded connection or interference fit methods to achieve detachable connection. In specific applications, in order to achieve rotation, it can be detachably connected to a rotating structure such as a hinge, and connected to the chassis through a hinge to achieve the disassembly and rotation of the anti-winding component 30.

[0070] In some embodiments, Fig.10As shown, the cleaning member 20 includes an endless belt 21 and at least two rollers 22, the endless belt 21 can be rotatably wrapped around the at least two rollers 22 to clean the surface to be cleaned, and the anti-winding member 30 is used to interfere with the long strips of garbage on the cleaning member 20 when the endless belt 21 is wrapped around the two rollers 22 to collect the long strips of garbage on the cleaning member 20. In this embodiment, the number of rollers 22 can be two, three or more. The arrangement of at least two rollers 22 can be used to support and tension the endless belt 21 on the one hand, so that the endless belt 21 forms a preset annular structure, and can be used to guide the endless belt 21 to rotate on the other hand. In a specific application, when the ring-shaped belt 21 is pressed against the surface to be cleaned and rotates, the surface to be cleaned can be cleaned and the garbage on the surface to be cleaned can be transferred to a preset position. The preset position can be a recovery container of the cleaning device 100. When the ring-shaped belt 21 rotates, it interferes with the anti-winding component 30, so that the long strips of garbage on the ring-shaped belt 21 are collected by the anti-winding component 30. At this time, the anti-winding component 30 also rotates to wind the long strips of garbage to prevent the long strips of garbage from returning to the ring-shaped belt 21, thereby preventing the ring-shaped belt 21 from being entangled by long strips of garbage such as hair and flocs, thereby preventing the ring-shaped belt 21 from getting stuck and affecting the cleaning effect.

[0071] In some embodiments, Figure 1-Figure 4 As shown, the cleaning device 100 also includes a handheld rod body 50 ( Figure 1 Only the lower end of the hand-held rod body 50 is shown, and the overall structure of the hand-held rod body 50 is not shown). The hand-held rod body 50 is rotatably connected to the bottom shell 12, and the upper cover 11 is provided with an avoidance groove 114 in the middle of one side facing the hand-held rod body 50 to avoid interference with the hand-held rod body 50 when the hand-held rod body 50 rotates. In this embodiment, the hand-held rod body 50 can be used to facilitate user operation to control the moving direction of the cleaning device 100. The chassis 10 plays a bearing role to facilitate the installation of components such as the cleaning member 20.

[0072] like Figures 11 to 13 As shown, the embodiment of the utility model provides a cleaning device 100, which includes a chassis 10 and a cleaning member 20, the cleaning member 20 is mounted on the chassis 10, and the cleaning member 20 can rotate relative to the surface to be cleaned, so as to clean the surface to be cleaned 200. The chassis 10 includes an upper cover 11 and a bottom shell 12, the cleaning member 20 is mounted on the bottom shell 12, and the upper cover 11 is connected to the bottom shell 12 and is located on the side of the bottom shell 12 facing away from the surface to be cleaned 200.

[0073] The cleaning device 100 proposed in the embodiment of the utility model can effectively reduce the splashing of garbage and sewage remaining on the cleaning component 20 during the rotation of the cleaning component 20 by setting the upper cover 11 to cover the cleaning component 20, that is, it can maintain a good cleaning effect on the cleaning surface 200, and the user experience is also better.

[0074] In one embodiment, the upper cover 11 is detachably connected to the bottom shell 12. In this embodiment, when the cleaning member 20 needs to be cleaned or disassembled, the upper cover 11 can be removed first, and then the cleaning member 20 can be cleaned or disassembled. This embodiment facilitates the cleaning or disassembly of the cleaning member 20 and improves the convenience of use of the cleaning device 100.

[0075] like Fig.11 and Fig.13 As shown, in one embodiment, the cleaning member 20 includes an upper surface 20a, and the upper surface 20a includes a cleaning surface 20b opposite to the surface to be cleaned 200. In a specific embodiment, the upper surface 20a can be partially or completely covered by the upper cover 11, which can be determined according to actual design requirements.

[0076] like Fig.13 As shown, in one embodiment, the cleaning member 20 includes an obliquely disposed annular belt 21 , and a side of the annular belt 21 away from the surface 200 to be cleaned is an upper surface 20 a .

[0077] like Fig.13 As shown, in one embodiment, when the upper cover 11 is disassembled relative to the bottom shell 12, the cleaning surface 20b is partially exposed. In another embodiment, when the upper cover 11 is disassembled relative to the bottom shell 12, the cleaning surface 20b is fully exposed. In this embodiment, when the upper cover 11 is disassembled relative to the bottom shell 12, whether the cleaning surface 20b is partially exposed or the cleaning surface 20b is fully exposed, the cleaning component 20 can be placed under the faucet for washing. Specifically, after the operator disassembles the upper cover 11, the annular belt 21 of the cleaning component 20 is moved to the bottom of the faucet, and the annular belt 21 is driven to rotate. During the process of washing the annular belt 21 with water from the faucet, the annular belt 21 rotates continuously, so that the garbage or sewage on the entire annular belt 21 can be completely washed away. Compared with the existing method of removing the entire annular belt 21 as a whole for washing, the solution proposed in this embodiment greatly improves the convenience of washing the annular belt 21, and can effectively improve the user's experience.

[0078] In one embodiment, the cleaning member 20 is rotatably mounted on the bottom shell 12, so that the cleaning member 20 can adjust the gap between it and the surface to be cleaned 200. In this embodiment, when the cleaning device 100 moves on the surface to be cleaned 200 to perform cleaning work, if it encounters large-volume garbage, the bottom of the cleaning member 20 can be lifted up, so that the large-volume garbage can be guided to the main cleaning member 20 or the working area of ​​the main cleaning member 20 through the cleaning member 20, thereby achieving the effect that the cleaning member 20 can automatically adjust the gap between it and the surface to be cleaned 200 according to the size of the garbage, so that the cleaning device 100 can remove garbage of different sizes.

[0079] In one embodiment, the upper cover 11 is configured to rotate synchronously with the cleaning member 20 when the cleaning member 20 adjusts the gap between the cleaning member 20 and the surface to be cleaned 200. In this embodiment, the upper cover 11 can be kept close to the cleaning member 20. In some embodiments, the upper cover 11 is installed with a structure that acts on the cleaning member 20. For example, the upper cover 11 is installed with an anti-winding member that can clean up the long strips of garbage on the cleaning member 20. By setting the upper cover 11 to rotate synchronously with the cleaning member 20, the cleaning effect of the anti-winding member on the cleaning member 20 can be maintained. Moreover, by setting the upper cover 11 to rotate synchronously with the cleaning member 20, the anti-winding member can be kept in interference with the cleaning member 20 and rotate with the rotation of the cleaning member 20, thereby reducing the interference with the rotation of the cleaning member 20.

[0080] like Figures 11 to 13 As shown, in one embodiment, the upper cover 11 includes a movable cover 121 and a free cover 122, the movable cover 121 is detachably connected to the bottom shell 12, one end of the free cover 122 is a free end, and the other end is movably connected to one end of the movable cover 121. In this embodiment, by setting the free cover 122 and the movable cover 121 so that the movable cover 121 is connected, when the cleaning component 20 rotates relative to the bottom shell 12, the free cover 122 can move with the cleaning component 20. Similarly, in some embodiments, the free cover 122 is installed with a structure that acts on the cleaning component 20. For example, the free cover 122 is installed with an anti-winding component that can clean up the long strips of garbage on the cleaning component 20. By setting the upper cover 11 to rotate synchronously with the cleaning component 20, the cleaning effect of the anti-winding component on the cleaning component 20 can be maintained. At the same time, by setting the free cover 122 to rotate synchronously with the cleaning component 20, the anti-winding component can maintain interference with the cleaning component 20 and rotate with the rotation of the cleaning component 20, thereby reducing the interference with the rotation of the cleaning component 20.

[0081] like Fig.14 and Fig.15As shown, in one embodiment, a disassembly structure is provided between the movable cover 121 and the bottom shell 12, and the disassembly structure includes a plug-in structure 101 and at least one positioning structure 102, and the plug-in structure 101 is configured so that the movable cover 121 and the bottom shell 12 are concave-convexly matched in the direction of the forward and backward movement of the cleaning device 100, and the movable cover 121 is fixedly connected to the bottom shell 12 when the free cover 122 and the cleaning member 20 follow the movement. The positioning structure 102 is configured so that the movable cover 121 and the bottom shell 12 are positioned and installed.

[0082] like Fig.14 and Fig.15 As shown, in one embodiment, the plug-in structure 101 includes a groove 1011 and a plug-in 1012, the bottom shell 12 is provided with the groove 1011, and the movable cover 121 is provided with the plug-in 1012, and the plug-in 1012 and the groove 1011 are plugged in the direction in which the cleaning device 100 moves forward and backward. It should be noted that the positions of the groove 1011 and the plug-in 1012 can be interchanged, that is, the bottom shell 12 is provided with a disassembly part, and the movable cover 121 is provided with the groove 1011, which can be determined according to actual design needs.

[0083] like Fig.14 and Fig.15 As shown, in one embodiment, the positioning structure 102 includes a positioning hole 1021 and a positioning member 1022, the bottom shell 12 is provided with the positioning hole 1021, the movable cover 121 is provided with the positioning member 1022, and the positioning member 1022 and the positioning hole 1021 are plugged in the thickness direction of the movable cover 121. It should be noted that the positions of the positioning hole 1021 and the positioning member 1022 can be interchanged, that is, the bottom shell 12 is provided with the positioning member 1022, and the movable cover 121 is provided with the positioning hole 1021, which can be determined according to actual design needs.

[0084] like Fig.14 and Fig.15 As shown, in one embodiment, the positioning structure 102 is located on the side of the plug-in 1012 away from the free cover 122. It should be noted that the positioning structure 102 is located on the side of the plug-in 1012 away from the free cover 122, and the positioning structure 102 and the plug-in 1012 may be arranged in a straight line one after the other in the direction in which the cleaning device 100 advances, or the positioning structure 102 and the plug-in 1012 may be arranged in a straight line one after the other in the direction in which the cleaning device 100 advances, but not in a straight line, and the positioning structure 102 and the plug-in 1012 are staggered.

[0085] In an optional embodiment, the number of the positioning structure 102 and the number of the plug-in 1012 are both one, and the positioning structure 102 and the plug-in 1012 are arranged in a straight line or staggered in the direction of the cleaning device 100. Alternatively, the number of the plug-in 1012 is one, the number of the positioning structure 102 is two or more, and the positioning structure 102 and the plug-in 1012 can be staggered in the direction of the cleaning device 100, or one of the positioning structures 102 and the plug-in 1012 can be arranged in a straight line in the direction of the cleaning device 100, and the remaining positioning structures 102 and the plug-in 1012 can be staggered in the direction of the cleaning device 100. Or the number of plug-ins 1012 is two or more, the number of positioning structures 102 is two or more, the positioning structures 102 and the plug-ins 1012 may be all staggered in the direction of advancement of the cleaning device 100, or the positioning structures 102 and the plug-ins 1012 may be all aligned one-to-one in the direction of advancement of the cleaning device 100, or at least one positioning structure 102 and at least one plug-in 1012 may be arranged in a straight line in the direction of advancement of the cleaning device 100, and the remaining positioning structures 102 and plug-ins 1012 may be staggered in the direction of advancement of the cleaning device 100.

[0086] like Fig.14 and Fig.15 As shown, in one embodiment, two positioning structures 102 are provided, and the connection line of the two positioning structures 102 and the plug-in structure 101 is arranged in a triangle. Optionally, the connection line of the two positioning structures 102 and the plug-in structure 101 is arranged in an isosceles triangle, or in other words, the two positioning structures 102 are symmetrically arranged in the left and right directions of the cleaning device 100.

[0087] Taking the plug-in 1012 and the positioning member 1022 provided on the movable cover 121 as an example, the installation and disassembly process between the movable cover 121 and the bottom shell 12 is as follows: when installing the movable cover 121, the operator aligns the plug-in 1012 on the movable cover 121 with the groove 1011 on the bottom shell 12, and then pushes the movable cover 121 toward the rear side of the bottom shell 12 until the plug-in 1012 is embedded in the groove 1011. When the plug-in 1012 is installed in place, the positioning member 1022 on the movable cover 121 can be automatically embedded in the positioning hole 1021 or manually pressed by the operator to be embedded in the positioning hole 1021, that is, the installation of the movable cover 121 is completed. It should be noted that due to the limiting effect of the plug-in 1012 and the groove 1011, when the operator manually flips the free cover 122 upward, or the free cover 122 rotates upward together with the cleaning member 20, the movable cover 121 will not fall off from the bottom shell 12. When the movable cover 121 needs to be removed from the bottom shell 12, the operator can bend the side of the movable cover 121 away from the free cover 122 upward, and the positioning member 1022 withdraws from the positioning hole 1021. When the operator continues to bend the side of the movable cover 121 away from the free cover 122 upward, the plug 1012 automatically withdraws from the groove 1011, and the entire movable cover 121 can be removed from the bottom shell 12. It can be seen that the structural design of the plug 1012 and the groove 1011, the positioning member 1022 and the positioning hole 1021 makes it very simple to disassemble and assemble the movable cover 121 and the bottom shell 12, thereby improving the usability of the cleaning device 100.

[0088] Optionally, since the plug-in 1012 and the groove 1011 are plugged into each other along the direction of the forward and backward movement of the cleaning device 100, when the operator manually flips the free cover 122 upward, or the free cover 122 rotates upward together with the cleaning component 20, the force direction of the free cover 122 is upward, and at the same time, the force on the end of the movable cover 121 close to the free cover 122 is also upward, so it will be restricted by the plug-in 1012 and the groove 1011, and the plug-in 1012 and the groove 1011 will not be separated, thereby ensuring that even if the movable cover 121 is subjected to force at the end close to the free cover 122, it will not be affected.

[0089] Furthermore, by providing the positioning member 1022 and the positioning hole 1021 , which are located on the side of the plug 1012 and the groove 1011 away from the free cover 122 , a triangular stable structure is achieved.

[0090] like Figures 14 to 16 As shown, in one embodiment, the movable cover 121 is provided with a plug-in 1012, and the side of the plug-in 1012 facing away from the free cover 122 includes a guide limit surface 1013, the guide limit surface 1013 extends downward from the movable cover 121 in a direction away from the free cover 122 and toward the bottom of the chassis 10, and the groove 1011 is provided with a guide surface 1014 adapted to the guide limit surface 1013.

[0091] It should be noted that the cooperation between the guide limit surface 1013 and the guide surface 1014 plays a guiding role in the process of installing the movable cover 121 on the bottom shell 12. Specifically, since the guide limit surface 1013 extends downward from the movable cover 121 in a direction away from the free cover 122 and toward the bottom of the chassis 10, the extension direction of the guide surface 1014 is consistent with that of the guide limit surface 1013. Therefore, in the process of the operator pushing the movable cover 121 toward the rear side of the bottom shell 12, under the guidance of the cooperation between the guide surface 1014 and the guide limit surface 1013, the movable cover 121 has a gradual descending process, which can guide the positioning member 1022 to embed into the positioning hole 1021.

[0092] like Fig.16 As shown, in one embodiment, the guide limit surface 1013 is a convex arc surface or a concave arc surface. The "convex arc surface" refers to the guide limit surface 1013 being a surface with an upward arch in the middle, and conversely, the "concave arc surface" refers to the guide limit surface 1013 being a surface with a downward depression in the middle. It should be noted that the coordination between the arc surfaces has a better fit, so that the movable cover 121 has better stability after being installed on the bottom shell 12, and reduces the deflection of the two sides of the movable cover 121 due to the poor fit between the plug 1012 and the groove 1011.

[0093] It should also be noted that the guide limit surface 1013 and the guide surface 1014 are not limited to being set as downwardly inclined surfaces. For example, in some other embodiments, the guide limit surface 1013 and the guide surface 1014 may also be horizontally extending surfaces, which can be determined according to actual design requirements.

[0094] It should be noted that the above-mentioned “downward”, “upward”, “rear”, “forward”, “left and right”, and “horizontal” all refer to the orientation of the cleaning device 100 in a normal use state.

[0095] like Fig.11 As shown, in one embodiment, the cleaning device 100 further includes a handheld rod body 50 , which is connected to the bottom shell 12 , and an operator drives the cleaning device 100 forward, backward and turns by means of the handheld rod body 50 .

[0096] like Fig.11 and Fig.15As shown, in one embodiment, the bottom shell 12 further includes a hinged portion 60 for hinged connection with the hand-held rod body 50, and the groove 1011 is provided on the side of the hinged portion 60 facing the forward direction of the cleaning device 100. The movable cover 121 further includes an avoidance groove 1211 for avoiding the hinged portion 60, and the plug-in 1012 is located in the avoidance groove 1211. It should be noted that the plug-in 1012 can also be provided on the side of the hinged portion 60 facing the forward direction of the cleaning device 100, and the groove 1011 is located in the avoidance groove 1211, which can be determined according to actual design needs.

[0097] In one embodiment, the disassembly and assembly structure further includes a magnetic attraction structure (not shown), which is configured to cooperate with the plug-in structure 101 and / or the positioning structure 102 to magnetically attract the movable cover 121 and the bottom shell 12. In this embodiment, by providing the magnetic attraction structure, the connection between the movable cover 121 and the bottom shell 12 is more stable.

[0098] like Figures 17 to 19 As shown, in one embodiment, the upper cover 11 further includes a rotation connection structure 70, and the other end of the free cover 122 is rotationally connected to one end of the movable cover 121 through the rotation connection structure 70. In this embodiment, the other end of the free cover 122 is rotationally connected to one end of the movable cover 121 through the rotation connection structure 70, and when the cleaning member 20 rotates relative to the bottom shell 12, the free cover 122 can be turned upward together with the cleaning member 20. Similarly, in some embodiments, the free cover 122 is equipped with a structure that acts on the cleaning member 20, for example, the free cover 122 is equipped with a cleaning structure that can clean up the long strips of garbage on the cleaning member 20. By setting the upper cover 11 to rotate synchronously with the cleaning member 20, the cleaning effect of the cleaning structure on the cleaning member 20 can be maintained. It should be noted that by setting the other end of the free cover 122 to be rotatably connected to one end of the movable cover 121 through the rotating connection structure 70, in a usage scenario, when the cleaning component 20 needs to be cleaned, the operator can flip the free cover 122 upward to expose the cleaning component 20, thereby improving the convenience of cleaning the cleaning component 20.

[0099] In one embodiment, the rotating connection structure 70 includes at least one of a hinge structure, a flexible structure, an elastic structure, and a pleated structure.

[0100] like Fig.17As shown, in one embodiment, the rotating connection structure 70 includes a pleated buckle structure 71, and the other end of the free cover 122 is integrally formed with one end of the movable cover 121 through the pleated buckle structure 71. In a specific embodiment, the pleated buckle structure 71 connects the sheet of the movable cover 121 and the free cover 122, and the thickness of the sheet is thinner than that of the movable cover 121 and the free cover 122, so that the movable cover 121 and the free cover 122 can be relatively repeatedly bent at the sheet, similar to the connection structure between the lid and the lock of a plastic lunch box. Optionally, the movable cover 121, the free cover 122 and the pleated buckle structure 71 are integrally formed with plastic material.

[0101] like Fig.18 As shown, in one embodiment, the rotating connection structure 70 includes a flexible structure 72, which is a flexible or soft connection member, and opposite ends of the connection member are respectively connected to the movable cover 121 and the free cover 122.

[0102] like Fig.18 and Fig.19 As shown, in one embodiment, the rotating connection structure 70 includes a flexible structure 72 and a hinge structure 73, the flexible structure 72 is a flexible or soft connecting member, the opposite ends of the connecting member are respectively connected to the movable cover 121 and the free cover 122, and the free cover 122 is hinged to the movable cover 121 through the hinge structure 73.

[0103] like Fig.18 and Fig.19 As shown, in one embodiment, when the rotating connection structure 70 includes a flexible structure 72 and a hinge structure 73, two connecting members are provided; the hinge structure 73 is located in the middle part of the other end of the free cover 122, and the two connecting members are respectively located on opposite sides of the hinge structure 73 and are arranged in parallel along the width direction of the movable cover 121.

[0104] Of course, it is not limited to the above implementation mode. For example, in another embodiment, there is one connecting member and two hinge structures 73. The connecting member is located in the middle of one end of the movable cover 121, and the two hinge structures 73 are respectively located on opposite sides of the connecting member.

[0105] like Fig.18 and Fig.19 As shown, in one embodiment, when the rotating connection structure 70 includes a flexible structure 72 and a hinge structure 73, or when the rotating connection structure 70 includes a hinge structure 73, the hinge structure 73 includes a rotating shaft portion 731 and a rotating groove 732, one of the one end of the movable cover 121 and the other end of the free cover 122 is provided with a rotating shaft portion 731, and the other is provided with a rotating groove 732, the rotating shaft portion 731 and the rotating groove 732 are matched in a concave-convex manner, and can rotate in the rotating groove 732 and around the central axis of the rotating shaft portion 731.

[0106] In one embodiment, the rotating connection structure 70 is also used to provide the free cover 122 with an elastic force toward the cleaning member 20. In this embodiment, the free cover 122 can be kept close to the cleaning member 20 by the elastic force of the elastic force. Optionally, the elastic force can be provided by a torsion spring installed on the hinge structure 73. Of course, it is not limited to a torsion spring. In the above-mentioned structures of the flexible structure 72 and the pleated buckle structure 71, the flexible structure 72 and the pleated buckle structure 71 can be provided with a certain elastic force or a restorable deformation force, so that the free cover 122 can be kept close to the cleaning member 20.

[0107] like Fig.19 As shown, in one embodiment, the rotation groove 732 is recessed at the other end of the free cover 122 , and the rotation shaft portion 731 is connected to one end of the movable cover 121 .

[0108] In one embodiment, the hinge structure 73 further includes a limiting member (not shown), which is used to cooperate with the rotation groove 732 to limit the rotation of the rotation shaft portion 731 in the rotation groove 732 .

[0109] like Fig.15 and Fig. 20 As shown, in one embodiment, the bottom shell 12 includes two first side panels 111 arranged opposite to each other, and the free cover 122 includes two second side panels 112 arranged opposite to each other, and the two second side panels 112 are respectively nested with the two first side panels 111. Among them, "the two second side panels 112 are respectively nested with the two first side panels 111" can mean that the two second side panels 112 are arranged between the two first side panels 111, or the two first side panels 111 are arranged between the two second side panels 112, or the two second side panels 112 and the two first side panels 111 are staggered, which can be determined according to actual design needs.

[0110] In one embodiment, the rotation connection structure 70 is specifically an elastic rotation structure, which can be used to provide an elastic restoring force for the free cover 122 to twist toward the cleaning member 20 .

[0111] Optionally, by applying an elastic restoring force to the free cover 122 to twist it toward the cleaning component 20, the free cover 122 can maintain abutment with the cleaning component 20 or maintain a suitable distance, thereby reducing the movement space of garbage / sewage and effectively enhancing the abutment effect between the anti-winding component 30 and the cleaning component 20 to improve the processing capacity of the anti-winding component 30.

[0112] In an optional embodiment, by applying an elastic restoring force to the free cover 122 to twist the cleaning member 20 , the free cover 122 can drive the anti-winding assembly 30 to directly elastically abut against the cleaning member 20 , thereby improving the processing capacity of the anti-winding assembly 30 .

[0113] In an optional embodiment, the free cover 122 may also be directly elastically abutted against the bottom shell 12 (spaced apart from the cleaning component 20). When the cleaning component 20 adjusts the gap between it and the surface to be cleaned, the cleaning component 20 will rotate toward the free cover 122. At this time, an elastic restoring force is applied to the free cover 122 to twist the cleaning component 20, so that it can elastically abut against the anti-winding component 30 on the rotating free cover 122.

[0114] In an alternative embodiment, the cleaning member 20 may include a support frame, and a roller or an endless belt disposed on the support frame.

[0115] In an optional embodiment, the cleaning component 20 includes a soft surface or a deformable structure (taking an annular belt as an example, it is soft in itself, and on the other hand, the annular belt is rotatably arranged between two rollers, and the middle part thereof is deformable), so the free cover 122 drives the anti-winding component 30 to elastically abut against the cleaning component 20. Since the cleaning component 20 also has a certain deformation ability, the cleaning component 20 and the anti-winding component 30 are elastically abutted against each other. It should be noted that the elastic force of this elastic abutment can be generated by the cleaning component 20 and / or (the free cover 122), which is not limited here.

[0116] Optionally, since the cleaning member 20 is a deformable structure, the free cover 122 drives the anti-winding assembly 30 to elastically abut against the cleaning member 20 , so that the cleaning member 20 is deformed, and the free cover 122 can abut against the bottom shell 12 .

[0117] In an optional embodiment, the rotating structure can be a flexible part, which achieves elasticity through the flexible part's inherent recoverable deformation ability, or it can be a hinged structure, which achieves elasticity by adding a torsion spring to the hinged structure, or it can be other structures that can provide elastic torsional force, which is not specifically limited here.

[0118] It should be noted that the two second side panels 112 and the two first side panels 111 are not limited to the above-mentioned nested implementation. For example, in another embodiment, the two second side panels 112 are overlapped with the two first side panels 111 respectively.

[0119] like Fig.15As shown, in one embodiment, the cleaning device 100 further includes an anti-winding member 30, which is disposed on the side of the free cover 122 facing the cleaning member 20, and the opposite ends of the anti-winding member 30 are respectively connected to the two second side plates 112, and elastically press the upper surface 20a of the cleaning member 20. In this embodiment, the anti-winding member 30 can hook the long strips of garbage on the cleaning member 20, such as hair, floccules, etc., during the rotation of the cleaning member 20, to prevent the cleaning member 20 from being entangled by the long strips of garbage, causing jamming and affecting the cleaning effect.

[0120] It should be noted that, in the above-mentioned embodiment, the free cover 122 is configured to rotate synchronously with the cleaning member 20 when the cleaning member 20 adjusts the gap between it and the surface to be cleaned 200. In this embodiment, the positions of the anti-winding member 30 and the cleaning member 20 remain unchanged, so that no matter how the cleaning member 20 moves, the cleaning effect of the anti-winding member 30 on the long strips of garbage on the cleaning member 20 can be maintained.

[0121] In one embodiment, the anti-winding member 30 is rotatably mounted on the chassis 10 and is arranged to interfere with the cleaning member 20. The anti-winding member 30 is used to interfere with the long strips of garbage on the cleaning member 20 and rotate when the cleaning member 20 rotates, so as to collect the long strips of garbage on the cleaning member 20.

[0122] like Fig.15 and Fig.21 As shown, in one embodiment, the anti-winding member 30 includes a mounting member 31 and a hook member 32. The mounting member 31 is mounted on the chassis 10 and close to the cleaning member 20. The hook member 32 is arranged on the outer wall of the mounting member 31. The hook member 32 is used to interfere with the long strips of garbage on the cleaning member 20 when the cleaning member 20 rotates, and rotate relative to the mounting member 31 or rotate simultaneously with the mounting member 31, so that the long strips of garbage on the cleaning member 20 can be entangled on the hook member 32.

[0123] like Fig. 22 As shown, in one embodiment, the mounting member 31 is a rod-shaped member, and the mounting member 31 can be detachably mounted on the upper cover 11. The hook member 32 includes a sleeve 321 and a strip 322 that is unfolded into a long strip. The sleeve 321 can be detachably mounted on the mounting member 31, and the strip 322 is spirally wound around the outer wall of the sleeve 321.

[0124] like Fig.23As shown, in some embodiments, the cleaning member 20 includes an endless belt 21 and at least two rollers 22, the endless belt 21 can be rotatably wrapped around the at least two rollers 22 to clean the surface to be cleaned 200, and the anti-winding member 30 is used to interfere with the long strips of garbage on the cleaning member 20 when the endless belt 21 is wrapped around the two rollers 22 to collect the long strips of garbage on the cleaning member 20. In this embodiment, the number of rollers 22 can be two, three or more. The arrangement of at least two rollers 22 can be used to support and tension the endless belt 21 on the one hand, so that the endless belt 21 forms a preset annular structure, and can be used to guide the endless belt 21 to rotate on the other hand. In a specific application, when the ring-shaped belt 21 is pressed against the surface 200 to be cleaned and rotates, the surface 200 to be cleaned can be cleaned and the garbage on the surface 200 to be cleaned can be transferred to a preset position. The preset position can be a recovery container of the cleaning device 100. When the ring-shaped belt 21 rotates, it interferes with the anti-winding component 30, so that the long strips of garbage on the ring-shaped belt 21 are collected by the anti-winding component 30. At this time, the anti-winding component 30 also rotates to wind the long strips of garbage to prevent the long strips of garbage from returning to the ring-shaped belt 21, thereby preventing the ring-shaped belt 21 from being entangled by long strips of garbage such as hair and flocs, thereby preventing the ring-shaped belt 21 from getting stuck and affecting the cleaning effect.
