[0003] Traditional cleaning devices include a rotary brush, and the rotation of the rotary brush can perform cleaning operations on the ground. However, after the rotary brush runs for a period of time, the bristles on the rotary brush are prone to collapse or even stick together, resulting in poor cleaning effect of the rotary brush subsequently. Summary of the Invention

[0009] Wherein, the cleaning main body has a first state in which the rotary brush rotates forward and the dirt scraping member is used to scrape the dirt on the rotary brush, and a second state in which the rotary brush rotates in the reverse direction and the dirt scraping member is used to comb the bristles on the rotary brush.
[0010] In one embodiment, a recess extending along the preset direction is provided on either the dirt scraping member or the seat body, and a convex portion capable of slidingly cooperating with the recess is provided on the other of the dirt scraping member and the seat body.
[0011] In one embodiment, the dirt scraping assembly further includes an elastic member, the elastic member is connected between the seat body and the dirt scraping member, and the elastic member is configured to provide an elastic force for driving the dirt scraping member to abut against the outer peripheral surface of the rotary brush along the preset direction.
[0012] In one embodiment, a guiding channel extending along the preset direction is formed in the scraping member, the elastic member is limited in the guiding channel, and its opposite ends are respectively in contact with the inner wall of the guiding channel and the seat body.
[0013] In one embodiment, the seat body includes a seat main body and an assembly body. The assembly body is rotatably assembled on the seat main body. The scraping member is connected to the assembly body, and the elastic member is connected between the assembly body and the scraping member.
[0014] The rotation axis of the assembly body is arranged parallel to the rotation axis of the roller brush.
[0015] In one embodiment, the seat body further includes a limiting body provided on the seat main body. The cleaning main body further includes a reset member. The reset member and the limiting body are located on the rotation path of the assembly body and are respectively arranged on opposite sides of the assembly body.
[0016] The reset member is configured to provide a reset force for driving the assembly body to abut against the limiting body. When the cleaning main body is in the first state, the assembly body abuts against the limiting body. When the cleaning main body is in the second state, the assembly body is separated from the limiting body.
[0017] In one embodiment, a rotating shaft is formed on the assembly body, and a rotating hole is formed in the seat main body. The rotating shaft is rotatably inserted into the rotating hole.
[0018] The reset member is a torsion spring. The torsion spring has a torsion spring coil and a first end and a second end protruding relative to the torsion spring coil. The torsion spring coil is sleeved on the rotating shaft. The first end abuts against the seat main body, and the second end abuts against the assembly body.

When the cleaning main body is in the second state, the roller brush rotates reversely relative to the seat body, and the dirt scraping member can comb the roller brush reversely. Since the dirt scraping member is telescopically assembled on the seat body, the dirt scraping member can always abut against the outer peripheral surface of the roller brush. In this way, even if the bristles on the outer surface of the roller brush are collapsed under the action of the dirt scraping member, resulting in a decrease in the outer diameter of the roller brush, the dirt scraping member can still abut against the outer peripheral surface of the roller brush and effectively comb the bristles, so as to reduce the risk of collapse and caking, thereby helping to reduce the risk of poor cleaning effect caused by the collapse of the bristles.

[0038] Please refer to Figure 1 , this application provides a cleaning device that can be used to clean the ground. Among them, the cleaning device can be a floor washer, a sweeping robot, a mopping robot, etc. The cleaning main body 1 is the part of the cleaning device that can walk on the ground and perform cleaning operations. The following embodiments will be described by taking the cleaning device as a floor washer as an example.
[0039] The cleaning device includes a frame (not shown in the figure), a clean water tank (not shown in the figure), a suction assembly (not shown in the figure), a sewage tank (not shown in the figure), a cleaning main body 1, and a control system (not shown in the figure). Among them, the cleaning main body 1 is arranged at the bottom of the frame, the clean water tank is arranged on the frame and is in fluid communication with the cleaning main body 1 to supply clean water to the cleaning main body 1; the sewage tank is arranged on the frame and is in fluid communication with the cleaning main body 1; the suction assembly is arranged on the frame and is connected to the sewage tank, and the suction assembly can create a negative pressure in the sewage tank to recover the sewage after cleaning by the cleaning main body 1 to the sewage tank; the control system controls the clean water tank to supply clean water to the cleaning main body 1 and controls the suction assembly to recover the sewage after cleaning by the cleaning main body 1 into the sewage tank.
[0040] Please refer to Figure 2 and Figure 3 at the same time. Among them, the cleaning main body 1 includes a seat body 10, a rotary brush 20, and a dirt scraping assembly 30. The rotary brush 20 is rotatably connected to the seat body 10. The dirt scraping assembly 30 includes a dirt scraping member 31. The dirt scraping member 31 is telescopically assembled on the seat body 10 and abuts against the outer peripheral surface of the rotary brush 20 along a preset direction. Among them, the cleaning main body 1 has a first state in which the rotary brush 20 rotates forward and the dirt scraping member 31 is used to scrape the dirt on the rotary brush 20, and a second state in which the rotary brush 20 rotates reversely and the rotary brush 20 is used to comb the bristles 23 on the rotary brush 20.
[0041] It can be understood that the dirt can be liquid dirt, such as sewage, or it can also be solid dirt. In the following embodiments, the dirt is taken as sewage as an example for illustration.
[0042] The seat body 10 is connected to the frame, and a rotary brush cavity 15 is formed on the seat body 10. The rotary brush 20 is rotatably arranged in the rotary brush cavity 15. The clean water tank is in communication with the rotary brush cavity 15 and is used to supply clean water to the rotary brush 20. The sewage tank is in fluid communication with the rotary brush cavity 15 and recovers sewage under the action of the suction assembly.
[0043] The dirt scraping member 31 can be a telescopic plate, a telescopic sheet, or other forms of telescopic dirt scraping structures. The dirt scraping member 31 can always abut against the outer peripheral surface of the rotary brush 20 along a preset direction through telescoping. Among them, the preset direction can be the radial direction of the rotary brush 20, or it can also be other directions that intersect both the radial direction of the rotary brush 20 and the extending direction of the rotary brush 20. In the following embodiments, the extending direction of the rotary brush 20 is taken as the first direction (such as Figure 2 the direction indicated by arrow X), the radial direction of the rotary brush 20 and the preset direction are both the second direction (such as Figure 1 the direction indicated by arrow Y), the dirt scraping member 31 extends along the first direction, and the dirt scraping member 31 abuts against the outer peripheral surface of the rotary brush 20 along the second direction as an example for illustration. Taking Figure 1 as an example, both the first direction and the second direction are horizontal directions.
[0044] The forward rotation of the rotary brush 20 can be represented by one of clockwise rotation and counterclockwise rotation, and the reverse rotation is the other of clockwise rotation and counterclockwise rotation, which is specifically determined according to the relative position between the rotary brush 20 and the dirt scraping member 31. The following embodiments are all based on Figure 1 the clockwise rotation of the middle rotary brush 20 as the forward rotation (such as Figure 1 the rotation direction indicated by the arrow a in Figure 1 ), and the counterclockwise rotation of the rotary brush 20 as the reverse rotation (such as
[0045] the rotation direction indicated by the arrow b in
[0046] for illustration. Figure 4 and Figure 5 In traditional cleaning devices, after the rotary brush 20 operates for a period of time, the bristles 23 on the rotary brush 20 are prone to collapse or even agglomerate, resulting in poor subsequent cleaning effect of the rotary brush 20. Moreover, the collapsed rotary brush 20 is also prone to wear, has a short service life, and after the cleaning operation is completed, the drying time of the rotary brush 20 is also long, and the user experience is poor.
[0047] Please refer to
[0048] simultaneously. In this application, when the cleaning main body 1 is in the first state, the rotary brush 20 rotates forward relative to the seat body 10, and the ground can be cleaned. The dirt scraping member 31 abuts against the rotary brush 20, and can scrape off the sewage on the rotary brush 20, and the scraped sewage can be recycled into the sewage tank. When the cleaning main body 1 is in the second state, the rotary brush 20 rotates reversely relative to the seat body 10, and the dirt scraping member 31 can comb the rotary brush 20 reversely. Since the dirt scraping member 31 is telescopic, the dirt scraping member 31 can always abut against the outer peripheral surface of the rotary brush 20. In this way, even if the bristles 23 on the outer surface of the rotary brush 20 are collapsed under the action of the dirt scraping member 31, resulting in a decrease in the outer diameter of the rotary brush 20, the dirt scraping member 31 can still abut against the outer peripheral surface of the rotary brush 20 and effectively comb the bristles 23, thereby helping to reduce the risk of a series of problems caused by the collapse of the bristles 23, making the cleaning main body 1 have a better user experience, the rotary brush 20 in the cleaning main body 1 has a longer service life, good cleaning effect, and fast drying speed.
[0049] It is worth mentioning that the cleaning main body 1 can be switched to the second state after each execution of the first state is completed, or it can also be switched to the second state after multiple executions of the first state, which can be specifically set according to needs.
[0050] Among them, the elastic member 32 can be a spring, a highly elastic rubber or other elastic components. The choice of the material for manufacturing the elastic member 32 can be set according to requirements, as long as it is ensured that the scraping member 31 can always be in contact with the rolling brush 20 under the action of the elastic member 32.
[0051] During initial assembly, by compressing the elastic member 32, the scraping member 31 is contracted, so that the scraping member 31 can be installed between the elastic member 32 and the rolling brush 20; thereafter, the scraping member 31 elongates under the rebound action of the elastic member 32 and abuts against the outer peripheral surface of the rolling brush 20.
[0052] By providing the elastic member 32, the scraping member 31 can automatically expand and contract and abut against the outer peripheral surface of the rolling brush 20. In this way, it can be ensured that the scraping member 31 can always abut against the outer peripheral surface of the rolling brush 20 and perform scraping or brushing the bristles.
[0053] Please refer to again Figure 2 and Figure 3 , in some embodiments of the present application, a guiding channel 311 extending along a preset direction is formed on the scraping member 31. The elastic member 32 is limited in the guiding channel 311, and its opposite ends are respectively in contact with the inner wall of the guiding channel 311 and the seat body 10.
[0054] Among them, the guiding channel 311 can be a blind hole, a notch or other shapes, and the elastic member 32 is a spring.
[0055] The guiding channel 311 extends along the second direction and is used to accommodate the elastic member 32. By providing the guiding channel 311, the elastic member 32 is directly compressed and placed into the guiding channel 311, and then the external force is released. The elastic member 32 can abut between the seat body 10 and the scraping member 31 and drive the elastic member 32 to abut against the rolling brush 20. By providing the guiding channel 311, on the one hand, the assembly of the elastic member 32 can be facilitated, and on the other hand, the guiding member can guide the deformation of the elastic member 32 so that the elastic member 32 can deform stably. Furthermore, the movement of the scraping member 31 is also more stable.
[0056] In some embodiments, both the guiding channel 311 and the elastic member 32 are two and correspond one by one. The two guiding channels 311 are spaced apart at opposite ends of the scraping member 31, and each elastic member 32 is received in the corresponding guiding channel 311. In this setting, the two elastic members 32 can cooperate to stably push the scraping member 31 to move.
[0057] Of course, in some other embodiments, the number of the guiding channels 311 and the elastic members 32 is not limited to the above one. For example, there may be one elastic member 32 and one guiding channel 311. The guiding channel 311 is disposed at the middle position of the scraping member 31, and the elastic member 32 is located within the guiding channel 311. Alternatively, there are more than three conducting channels and elastic members 32 which correspond to each other one by one. All the guiding channels 311 are spaced along the extending direction of the scraping member 31, and each elastic member 32 is disposed within the corresponding guiding channel 311.
[0058] In some embodiments, either the scraping member 31 or the seat body 10 is provided with a recess 312 extending along a preset direction, and the other one of the scraping member 31 and the seat body 10 is provided with a convex portion 121 capable of slidingly mating with the recess 312.
[0059] For example, the convex portion 121 may be formed on the scraping member 31, and the recess 312 may be formed on the seat body 10; or alternatively, the recess 312 may be formed on the scraping member 31, and the convex portion 121 may be formed on the seat body 10. The following embodiments will be described by taking the example that the convex portion 121 is formed on the seat body 10 and the recess 312 is formed on the scraping member 31. Among them, the recess 312 may be a convex column, a convex block or other convex structures, and the recess 312 may be a strip-shaped hole, a groove or other recessed structures.
[0060] The number of the recesses 312 and the convex portions 121 is equal and they correspond to each other one by one. Among them, the number of the recesses 312 and the convex portions 121 may be set according to requirements. For example, there are two recesses 312 and two convex portions 121. The two recesses 312 are located at opposite ends of the scraping member 31 and cooperate with the two convex portions 121 correspondingly. Also for example, there are more than three recesses 312 and coatings. All the recesses 312 are spaced along the extending direction of the scraping member 31 and cooperate with all the convex portions 121 correspondingly. The convex portion 121 is inserted into the recess 312 and is clamped with the recess 312, so that the connection between the scraping member 31 and the seat body 10 can be realized, and the assembly is simple and convenient. When the cleaning main body 1 is in the first state, the roller brush 20 works and the bristles 23 thereon are easily collapsed, resulting in a smaller diameter of the roller brush 20. At this time, the elastic member 32 can push the scraping member 31 to move along the preset direction and abut against the roller brush 20. Since the recess 312 extends along the preset direction, under the action of the elastic member 32, while the convex portion 121 is embedded into the recess 312, it can also slide relative to the recess 312 along the preset direction to avoid interfering with the movement of the scraping member 31. At the same time, the cooperation between the convex portion 121 and the recess 312 can also guide the movement of the scraping member 31, which helps to improve the stability of the movement of the scraping member 31 and reduce the risk of the scraping member 31 deviating from the roller brush 20.
[0061] In some embodiments, the seat body 10 includes a seat main body 11 and an assembly body 12. The assembly body 12 is rotatably assembled on the seat main body 11. The dirt scraping member 31 is coupled to the assembly body 12, and the elastic member 32 is connected between the assembly body 12 and the dirt scraping member 31. The rotation axis of the assembly body 12 is arranged parallel to the rotation axis of the roller brush 20.
[0062] Wherein, the rotation axis of the assembly body 12 extends in the first direction. The dirt scraping member 31 drives the assembly body 12 to rotate relative to the seat main body 11 under the action of the roller brush 20, and the rotation directions of the assembly body 12 and the roller brush 20 are opposite.
[0063] For example, Figure 1 taking [the following] as an example, when the cleaning main body 1 is in the first state, the roller brush 20 rotates clockwise, and it exerts an upward acting force on the dirt scraping member 31, so that the dirt scraping member 31 can drive the assembly body 12 to rotate counterclockwise relative to the seat main body 11; when in the second state, the roller brush 20 rotates counterclockwise, and it exerts a downward acting force on the dirt scraping member 31, so that the dirt scraping member 31 can drive the assembly body 12 to rotate clockwise relative to the seat main body 11.
[0064] Of course, whether the assembly body 12 rotates counterclockwise or clockwise relative to the seat main body 11, the rotation angle is relatively small to ensure that the dirt scraping member 31 can always be in contact with the roller brush 20 and be used for scraping dirt or combing the bristles 23. Wherein, the assembly body 12 can limit the rotation angle by being rotationally connected to the seat main body 11 in a damped manner, or the assembly body 12 can also limit the rotation angle by a limiting member provided on the seat main body 11 to ensure that the dirt scraping member 31 does not rotate at too large an angle and separate from the roller brush 20.
[0065] The roller brush 20 includes a roller brush shaft 21 and a flexible sleeve 22 sleeved outside the roller brush shaft 21. The flexible sleeve 22 can be formed by materials such as nylon, coral fleece, and sponge. When the dirt scraping member 31 abuts against the outer peripheral surface of the roller brush 20, a pit will be formed on the outer peripheral surface of the flexible sleeve 22. If the elastic force of the elastic member 32 is greater, the pit formed by the dirt scraping member 31 on the outer peripheral surface will be deeper, and the frictional force between the dirt scraping member 31 and the roller brush 20 will also be greater. Then, during the forward or reverse rotation of the roller brush 20, the resistance exerted by the dirt scraping member 31 will be greater. And the action of force is mutual, so no matter whether the roller brush 20 rotates forward or backward, the dirt scraping member 31 will be subjected to a reaction force exerted by the roller brush 20 that is equal in magnitude and opposite in direction to the resistance. Under the action of this reaction force, the dirt scraping member 31 is prone to breakage.
[0066] In this application, by arranging the assembly body 12 to be rotatably disposed on the seat main body 11, under the action of the force exerted by the roller brush 20, the dirt scraping member 31 and the assembly body 12 rotate synchronously relative to the seat main body 11. Figure 1For example, when the cleaning main body 1 is in the first state, the rotary brush 20 rotates clockwise and applies an upward force to the scraping member 31, so that the scraping member 31 rotates counterclockwise; when the cleaning main body 1 is in the second state, the rotary brush 20 rotates counterclockwise and applies a downward force to the scraping member 31, so that the scraping member 31 rotates clockwise. When the scraping member 31 rotates, the depth of the concave pit formed by the scraping member 31 pressing against the outer peripheral surface of the rotary brush 20 becomes smaller. Furthermore, the force applied by the rotary brush 20 to the scraping member 31 also becomes smaller, thereby reducing the risk of the scraping member 31 breaking under the force applied by the rotary brush 20.
[0067] In some embodiments, the seat body 10 further includes a limiting body 13 provided on the seat main body 11, and the cleaning main body 1 further includes a reset member 40. The reset member 40 and the limiting body 13 are located on the rotation path of the assembly body 12 and are respectively disposed on opposite sides of the assembly body 12; the reset member 40 is configured to provide a reset force for driving the assembly body 12 to abut against the limiting body 13; when the cleaning main body 1 is in the first state, the assembly body 12 abuts against the limiting body 13; when the cleaning main body 1 is in the second state, the assembly body 12 is separated from the limiting body 13.
[0068] Among them, the reset member 40 can be a sleeve spring, a torsion spring, a highly elastic rubber or other elastic members. The limiting body 13 is a convex structure protruding from the surface of the seat main body 11. When the cleaning main body 1 is in the first state, the assembly body 12 abuts against the limiting body 13 under the action of the reset force. In this way, the scraping member 31 can be located at a fixed position relative to the seat main body 11 and scrape the sewage on the rotary brush 20; when the cleaning main body 1 is in the second state, under the action of the rotary brush 20, the assembly body 12 is separated from the limiting body 13, and the assembly body 12 has a tendency to rotate to a position where it abuts against the limiting body 13 under the action of the reset force; when the cleaning main body 1 is switched to the first state again, under the action of the reset force, the assembly body 12 can rotate relative to the seat main body 11 until it abuts against the limiting body 13.
[0069] For Figure 1For example, the limiting body 13 and the reset member 40 are respectively distributed on opposite sides of the scraping member 31. Among them, the limiting body 13 is located on the upper side, and the reset member 40 is located on the lower side. When the cleaning main body 1 is in the first state, the rotary brush 20 rotates clockwise, and the scraping member 31 receives an upward acting force exerted by the rotary brush 20. However, under the action of the limiting body 13 and the reset member 40, the scraping member 31 and the assembly 12 can always maintain a horizontally arranged state and scrape the rotary brush 20. When the cleaning main body 1 is in the second state, the rotary brush 20 rotates counterclockwise, and the scraping member 31 receives a downward acting force exerted by the rotary brush 20, so that the scraping member 31 can drive the assembly 12 to rotate clockwise relative to the seat main body 11. During this process, the assembly 12 is separated from the limiting body 13, and the reset member 40 is further deformed. It is worth mentioning that the angle at which the scraping member 31 and the assembly 12 rotate relative to the seat main body 11 is fixed to ensure that the scraping member 31 can always abut against the rotary brush 20 and comb the bristles 23 on the rotary brush 20. When the cleaning main body 1 is switched to the first state again, the acting force exerted by the rotary brush 20 on the scraping member 31 is upward. Under the action of this acting force and the restoring force, the scraping member 31 drives the assembly 12 to rotate counterclockwise until the assembly 12 abuts against the limiting body 13.
[0070] It can be seen that by providing the reset member 40 and the limiting body 13, on the one hand, it can ensure that the scraping member 31 can float up and down under the action of the rotary brush 20 to prevent fracture due to excessive stress concentration. Moreover, the assembly 12 can also drive the scraping member 31 to rotate under the action of the reset member 40 until the assembly 12 returns to the position where it abuts against the limiting body 13, so that the scraping member 31 can stably perform scraping.
[0071] In some embodiments, a rotating shaft 122 is formed on the assembly 12, and a rotating hole 112 is formed in the seat main body 11. The rotating shaft 122 is rotatably inserted into the rotating hole 112; the reset member 40 is a torsion spring, and the torsion spring has a torsion spring coil 41 and a first end 42 and a second end 43 protruding relative to the torsion spring coil 41. The torsion spring coil 41 is sleeved on the rotating shaft 122, the first end 42 abuts against the seat main body 11, and the second end 43 abuts against the assembly 12.
[0072] The rotating shaft 122 is rotatably inserted into the rotating hole 112 to realize the rotational connection between the assembly 12 and the seat main body 11. The torsion spring coil 41 is sleeved on the rotating shaft 122, the first end 42 abuts against the seat main body 11, and the second end 43 abuts against the assembly 12, which can realize the assembly of the torsion spring.
[0073] When the cleaning body 1 is in the first state, the torsion spring coil 41 is twisted, and the reset member 40 can apply a reset force to the assembly 12, enabling the assembly 12 to abut against the limiting body 13; when the cleaning body 1 is in the second state, the torsion spring coil 41 is further twisted and continues to apply a reset force to the assembly 12. At this time, although the assembly 12 is separated from the limiting body 13, the assembly 12 has a tendency to rotate and move towards the limiting body 13.
[0074] In the present application, by arranging the torsion spring coil 41 sleeved on the rotating shaft 122, with the first end 42 abutting against the seat main body 11 and the second end 43 abutting against the assembly 12, the torsion spring assembly is simple, and the rotation of the scraping member 31 can be realized.
[0075] Please refer to again Figure 2 , in some embodiments, a limiting groove 111 is provided on the seat main body 11, and the torsion spring coil 41 is limited in the limiting groove 111.
[0076] For example, the limiting groove 111 extends in the first direction and has a first groove wall and a second groove wall oppositely arranged in the first direction. The torsion spring coil 41 is located in the limiting groove 111 and abuts between the first groove wall and the second groove wall. Another example is that the limiting groove 111 extends in the first direction and has a first groove wall and a second groove wall oppositely arranged in the first direction, and also has a third groove wall and a fourth groove wall oppositely arranged in the second direction. The torsion spring coil 41 abuts between the first groove wall and the second groove wall and also abuts between the third groove wall and the fourth groove wall. By providing the limiting groove 111, the limiting groove 111 can limit the torsion spring coil 41, so that the torsion spring has better installation stability, thereby reducing the risk of the torsion spring falling off from the rotating shaft 122, enabling the reset member 40 to stably apply a force to the scraping member 31 through the assembly 12 to drive the scraping member 31 to rotate.
[0077] In some embodiments, the seat body 10 further includes a stop body 14 provided on the seat main body 11. The stop body 14 is arranged on the rotation path of the assembly 12 and is on the same side of the assembly 12 as the reset member 40; when the cleaning body 1 is in the first state, the assembly 12 is separated from the stop body 14; when the cleaning body 1 is in the second state, the assembly 12 abuts against the stop body 14.
[0078] When the cleaning body 1 is in the second state, the scraping member 31 is subjected to the acting force of the roller brush 20. The scraping member 31 drives the assembly 12 to rotate relative to the seat main body 11 in the direction towards the stop body 14 until the assembly 12 abuts against the stop body 14. At this time, under the combined action of the stop force of the stop body 14, the acting force of the roller brush 20, and the reset force of the reset member 40, the assembly 12 abuts against the stop body 14, enabling the scraping member 31 to be located at a fixed position and comb the bristles 23 on the roller brush 20.
[0079] In summary, the limiting body 13 and the stop body 14 cooperate with each other to limit the rotation angle of the scraping member 31. Therefore, regardless of whether the cleaning main body 1 is in the first state or the second state, the scraping member 31 can stably act on the roller brush 20. It is worth mentioning that the limiting body 13 and the stop body 14 jointly form the above-mentioned limiting component.
[0080] Please refer to again Figure 3 , in some embodiments, the assembly 12 is a hollow structure with one end open and one end closed. The scraping member 31 has a connected mounting end 313 and a scraping end 314. The mounting end 313 extends into the assembly 12 and is connected to the assembly 12, and the scraping end 314 is located outside the assembly 12 and abuts against the roller brush 20.
[0081] Among them, the assembly 12 and the scraping member 31 extend in the same direction. The inner wall of the assembly 12 is provided with the above-mentioned convex portion 121, and the mounting end 313 of the scraping member 31 is provided with the above-mentioned concave portion 312. After the mounting end 313 extends into the assembly 12, the concave portion 312 and the convex portion 121 are in sliding fit.
[0082] In the present application, by setting, by extending the mounting end 313 of the scraping member 31 into the assembly 12 and connecting it to the assembly body, the assembly 12 can limit the scraping member 31 along the extension direction of the scraping member 31, thereby helping to improve the installation stability of the scraping member 31.
[0083] For the above-mentioned cleaning main body 1 and cleaning device, when the cleaning main body 1 is in the first state, the roller brush 20 rotates forward relative to the seat body 10, and the ground can be cleaned. The scraping member 31 abuts against the roller brush 20, and can scrape the sewage on the roller brush 20, and the scraped sewage can be recycled into the sewage tank. When the cleaning main body 1 is in the second state, the roller brush 20 rotates reversely relative to the seat body 10, and the scraping member 31 can comb the roller brush 20 reversely. The setting of the elastic member 32 enables the scraping member 31 to always abut against the outer peripheral surface of the roller brush 20. In this way, even if the bristles 23 on the outer surface of the roller brush 20 are crushed under the action of the scraping member 31, resulting in a decrease in the outer diameter of the roller brush 20, the scraping member 31 can still abut against the outer peripheral surface of the roller brush 20 and effectively comb the bristles 23 to reduce the risk of collapse and caking, thereby helping to reduce the risk of a series of problems caused by the collapse of the bristles 23.
[0084] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered to be within the scope described in this specification.
[0085] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
