[0002] A sweeping robot is a type of smart home appliance. With a certain degree of artificial intelligence, a sweeping robot can automatically complete floor cleaning in a room. A sweeping robot can use brushing and vacuuming to absorb debris on the ground into its own garbage collection box, thereby completing the function of floor cleaning. Generally, robots that complete sweeping, vacuuming, and mopping are also collectively classified as cleaning robots. A cleaning robot usually has a sewage tank, a sewage trough, a scraper, and a mopping assembly. The mopping assembly has a mopping bracket and a mop disposed on the mopping bracket. The mop rotates to achieve mopping and cleaning of the ground. The mop needs to be replaced after a period of use. How to conveniently replace the mop is a problem that all existing cleaning robots have.

[0058] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0059] In some of the processes described in the specification and claims of the present invention and the above-mentioned figures, multiple operations that appear in a specific order are included, but it should be clearly understood that these operations may not be executed in the order in which they appear in this article or executed in parallel. The sequence numbers of the operations, such as S101, S102, etc., are only used to distinguish between different operations, and the sequence numbers themselves do not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be executed in sequence or in parallel. It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., do not represent the order of precedence, and do not limit the "first" and "second" to be different types.

[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0061] like Figures 1 to 3 As shown, the present invention provides a mopping assembly 100, which includes a mopping bracket 110 and a mop 120, wherein the mopping bracket 110 includes a first bracket 10, a second bracket 20 and an intermediate shaft 30, and the first bracket 10 and the second bracket 20 can be relatively fixed by the intermediate shaft 30, and the first bracket 10 and / or the second bracket 20 can rotate around the intermediate shaft 30, so that the mopping bracket 110 has a flat state in the same plane and a relatively rotating folded state. Figure 1This is a schematic diagram of a mop being mounted on a mopping bracket. Figure 2 and Figure 3 It is a schematic diagram of the mopping bracket, where: Figure 2 The middle mopping bracket is in a flat state. Figure 3 The middle mopping bracket is in a folded state.

[0062] When the mopping bracket 110 is in a flat state, the mop cloth 120 is stretched on the surface of the mopping bracket 110 and abuts against the first roller 40 and the second roller 50 on the mopping bracket 110. When the first roller 40 and / or the second roller 50 are driven, the first roller 40 and the second roller 50 actively or passively rotate around the central axis of the roller. Since the mop cloth 120 is stretched on the first roller 40 and the second roller 50, when the first roller 40 or the second roller 50 rotates around the central axis of the roller, the mop cloth 120 drives the mop cloth 120 to rotate based on the friction between the first roller 40 and the second roller 50, thereby forming a crawler mopping assembly 100.

[0063] When the first bracket 10 and / or the second bracket 20 are rotated around the intermediate shaft 30, the mopping bracket 110 can be in a folded state. At this time, the mop cloth 120 is not stretched on the mopping bracket 110, and there is a gap between the mopping bracket 110 and the mop cloth 120, so that the mop cloth 120 and the mopping bracket 110 can be separated.

[0064] After the mop 120 is separated from the mop bracket 110, the user can use a new mop 120 to be mounted on the folded mop bracket 110. At this time, the first bracket 10 and / or the second bracket 20 are rotated around the intermediate shaft 30, and the mop bracket 110 can be switched from the folded state to the flat state. At this time, the mop 120 is stretched on the mop bracket 110, and the user can put the assembled mop bracket 110 into the mop slot of the cleaning robot. When the first roller 40 and / or the second roller 50 are driven, the mop 120 will be driven to rotate by the assembled mop bracket 110, and the replaced mop 120 can act on the work surface.

[0065] Among them, a first roller 40 is provided on one side of the first bracket 10, and the two ends of the first roller 40 are relatively fixed on the first bracket 10, and the first roller 40 can rotate on the first bracket 10 around the central axis of the roller; a first mounting member 401 is provided on the other side of the first bracket 10 (the side opposite to the first roller 40). A second roller 50 is provided on one side of the second bracket 20, and the two ends of the second roller 50 are relatively fixed on the second bracket 20, and the second roller 50 can rotate on the second bracket 20 around the central axis of the roller; a second mounting member 501 is provided on the other side of the second bracket 20. The first mounting member 401 on the first bracket 10 and the second mounting member 501 on the second bracket 20 are relatively fixed through the intermediate shaft member 30 (the fixing method can be seen in the following description), and the first bracket 10 and / or the second bracket 20 can rotate around the intermediate shaft member 30 through the first mounting member 401 and the second mounting member 501.

[0066] In this embodiment, the mutual cooperation of the first mounting member 401, the second mounting member 501 and the intermediate shaft member 30 can realize the mutual rotation of the first bracket 10 and the second bracket 20. In other examples, there can be multiple matching components (the first mounting member 401, the second mounting member 501 and the intermediate shaft member 30) as shown in the figure, so that the first bracket 10 and the second bracket 20 can be relatively fixed and stable and not easy to be damaged. When there are two such matching components, they are respectively located on the first bracket 10 (second bracket 20) near the two ends of the bracket; when there are three such matching components, the three matching components can divide the first bracket 10 (second bracket 20) equally, or two matching components can be respectively located on the first bracket 10 (second bracket 20) near the two ends of the bracket, and the other matching component is located in the middle of the first bracket 10 (second bracket 20); when there are four such matching components, two matching components are respectively located on the first bracket 10 (second bracket 20) near the two ends of the bracket, and the other two matching components are respectively located on both sides of the middle of the first bracket 10 (second bracket 20). Of course, there are other settings, which will not be described here.

[0067] Among them, one of the first roller 40 and the second roller 50 can be an active roller driven by a driving motor, and the other can be a driven roller rotated by the mop 120, or both the first roller 40 and the second roller 50 can be active rollers. When the mopping bracket 110 is in a flat state, the first roller 40 and the second roller 50 are respectively located on both sides of the mop bracket 120.

[0068] The mop 120 bracket provided in the embodiment of the present invention can be switched between a flat state and a folded state based on the rotation of the first and second brackets 20. In the folded state, it is convenient to replace the mop 120. In the flat state, the mop 120 bracket can remain flat and the mop 120 can be spread out to clean the work surface.

[0069] Please see Figure 4 , Figure 4 Schematic diagram of the second bracket, in some examples, the second mounting member 501 of the second roller 50 on the second bracket 20 includes a first component 501a and a second component 501b, and the first component 501a and the second component 501b have a through hole E. Correspondingly, the first mounting member 401 on the first bracket 10 has a through hole E, the first mounting member 401 is located between the first component 501a and the second component 501b, and the intermediate shaft member 30 passes through each through hole E to relatively fix the first mounting member 401 and the second mounting member 501. The second mounting member 501 also includes a limiting protrusion 501c located between the first component 501a and the second component 501b. A limiting groove 401c is provided on the first mounting member 401 on the first bracket 10. When the first bracket 10 and / or the second bracket 20 rotates around the intermediate shaft member 30, the limiting protrusion 501c of the second mounting member 501 on the second bracket 20 can be inserted into the limiting groove 401c of the first mounting member 401 on the first bracket 10 or can be released from the limiting groove 401c, so that the mopping bracket 110 can remain in a flat state or a folded state.

[0070] In some examples, the first mounting member 401 of the first bracket 10 is provided with two limiting grooves (a first limiting groove 401a and a second limiting groove 401b), see Figure 5 , Figure 6 When the mopping bracket 110 is in a flat state, the limiting protrusion 501c of the second mounting member 501 on the second bracket 20 can be inserted into the first limiting groove 401a of the first mounting member 401 on the first bracket 10, as shown in FIG. Figure 5 When the mopping bracket 110 is in the folded state, the limiting protrusion 501c of the second mounting member 501 on the second bracket 20 can be disengaged from the first limiting groove 401a and inserted into the second limiting groove 401b of the first mounting member 401 on the first bracket 10. Figure 6 , so that the mopping bracket 110 remains in a flat state or a folded state. Figure 5 The mopping bracket is shown in a flat state. Figure 6 The mopping bracket is shown in folded state

[0071] Please see Figure 7 , Figure 8 and Fig. 9 The mop 120 includes an inner lining 121, a cloth 122, and twisted edges 123 at both ends of the mop 120. The cloth 122 is on one side of the mop 120 facing the work surface, and the inner lining 121 is on the other side (inner side) of the mop 120. The inner lining 121 has a row of multiple mop convex teeth d. The material of the mop convex teeth d is the same as that of the inner lining 121. When the mop 120 is tied up into a tube, the row of multiple mop convex teeth d forms a ring (such as Figure 8), the inner side of the mop 120 has a plurality of mop convex teeth d arranged in a ring shape. In some other examples, the mop 120 has a plurality of rows of mop convex teeth d (such as Fig. 9 ), that is, multiple rows of mop convex teeth d arranged in an annular shape. The twisted edge 123 is a device used to interweave the warp and weft yarns at the edge of the mop 120 during the weaving process to prevent the yarns at the edge of the fabric from loosening and falling apart, so as to form a tight edge structure.

[0072] Please see Fig.10 The first roller 40 has a first annular groove 402 that is recessed toward the roller center axis. The first annular groove 402 has a plurality of roller convex teeth F that are arranged in a ring shape with the roller center axis as the center. The second roller 50 may have no annular groove or may have an annular groove. The outer side of the cylindrical mop 120 is the side that acts on the working surface (the side where the cloth on the mop is located). The inner side of the cylindrical mop 120 can be sleeved with the mopping bracket 110. The other side of the mop 120 relative to the working surface (the inner side of the mop 120) has a plurality of mop convex teeth d arranged in a ring shape. When the mop 120 is sleeved on the mopping bracket 110, the roller convex teeth F on the first roller 40 of the mopping bracket 110 and the convex teeth on the inner side of the mop 120 can mesh with each other (see Fig.11 ), when the first roller 40 is driven to rotate around the central axis of the roller, the mop 120 can be driven to rotate relative to the mopping bracket 110. Since the first roller and / or the second roller are provided with toothed grooves, they can mesh with the convex teeth of the mop, thereby preventing the mop from slipping during the rotation process.

[0073] Of course, the second roller 50 may also have an annular groove (second annular groove 502) that is recessed toward the roller center axis, and in this case, the first roller 40 has no annular groove. Similarly, the annular groove has a plurality of roller shaft convex teeth F, which are arranged in a ring shape with the roller center axis as the center. When the mop 120 is sleeved on the mopping bracket 110, the roller shaft convex teeth F on the second roller 50 of the mopping bracket 110 and the mop convex teeth d on the inner side of the mop 120 can mesh with each other, and when the second roller 50 is driven to rotate around the roller center axis, the mop 120 can be driven to rotate relative to the mopping bracket 110.

[0074] Alternatively, the first roller 40 may have a first annular groove 402 that is concave toward the roller center axis, the second roller 50 may have a second annular groove 502 that is concave toward the roller center axis, the first and second annular grooves 502 may have a plurality of roller shaft convex teeth F, the roller shaft convex teeth F may be arranged in an annular shape with the roller center axis as the center, and the connecting line of the annular grooves on the first roller 40 and the second roller 50 may be perpendicular to the first roller 40 and the second roller 50. When the mop 120 is sleeved on the mopping bracket 110, the mop convex teeth d on the inner side of the mop 120 may be meshed with the roller shaft convex teeth F of the annular grooves on the first roller 40 and the second roller 50, respectively, and when the first roller 40 and / or the second roller 50 are driven to rotate around the roller center axis, the mop 120 may be driven to rotate relative to the mopping bracket 110.

[0075] In order to facilitate the driving of the mop 120 to rotate, N annular grooves (N is a positive integer greater than 1) can be provided on the first roller 40, and the corresponding second roller 50 has no annular groove; or N annular grooves can be provided on the second roller 50, and the corresponding first roller 40 has no annular groove. Here, N annular grooves are provided on the first roller 40 as an example, and each annular groove has a plurality of roller convex teeth F. The mop 120 has N rows of annularly arranged mop convex teeth d on the other side of the working surface (the inner side of the mop 120). When the mop 120 is sleeved on the mopping bracket 110, the roller convex teeth F on each annular groove on the first roller 40 correspond to each row of mop convex teeth d on the mop 120, and the roller convex teeth F on each annular groove are respectively meshed with the mop convex teeth d on the mop 120. In the following description, N is equal to 2, and two annular grooves are provided on the first roller 40, and the two annular grooves are respectively located on the first roller 40 at positions close to the two ends of the first roller 40. The two annular grooves are provided with a plurality of roller teeth F. Correspondingly, the other side of the mop 120 relative to the working surface (the inner side of the mop 120) has two rows of annularly arranged mop teeth d. The roller teeth F on the two annular grooves can respectively mesh with the two rows of annularly arranged mop teeth d on the mop 120.

[0076] In some other examples, in order to facilitate driving the mop 120 to rotate, N annular grooves (N is a positive integer greater than 1) can be provided on the first roller 40, and N annular grooves can also be provided on the second roller 50. The straight line connecting at least one first annular groove 402 and a second annular groove 502 is perpendicular to the first roller 40, and each annular groove has a plurality of roller convex teeth F. The mop 120 has N rows of annularly arranged mop convex teeth d on the other side of the working surface (the inner side of the mop 120). When the mop 120 is sleeved on the mopping bracket 110, the roller convex teeth F on each annular groove on the first roller 40 correspond to each row of mop convex teeth d on the mop 120, and the roller convex teeth F on each annular groove are respectively meshed with the mop convex teeth d on the mop 120.

[0077] Of course, in order to save costs, N annular grooves (N is a positive integer greater than 1) can be provided on the first roller 40, and M second annular grooves 502 can be provided on the second roller 50. The straight line connecting at least one first annular groove 402 and one second annular groove 502 is perpendicular to the first roller 40. N and M are positive integers greater than 1, and M and N are not equal. In this example, the first and second annular grooves 502 have multiple roller convex teeth F, and the mop 120 has multiple rows of mop convex teeth d arranged in an annular shape. Multiple rows refers to the larger one of M and N. At this time, the roller convex teeth F on each annular groove are respectively meshed with N or M rows of mop convex teeth d arranged in an annular shape on the mop 120. For example, the first roller 40 has two annular grooves and corresponding roller convex teeth F, and the second roller 50 has only one annular groove and corresponding roller convex teeth F. The straight line connecting the one second annular groove 502 and one of the first annular grooves 402 is perpendicular to the first roller 40. The mop 120 has two rows of mop teeth d arranged in an annular shape. When the mop 120 is sleeved on the mopping bracket 110 and the mopping bracket 110 is in a flat state, the mop teeth d on the mop 120 correspond to the roller shaft teeth F of the two annular grooves on the first roller 40 respectively, and the roller shaft teeth F of one annular groove on the second roller 50 correspond to the roller shaft teeth F of one of the two annular grooves on the first roller 40.

[0078] In order to keep the first roller 40 on the mopping bracket 110 stable and not deformed, in some examples, a support member G is provided on the side of the first bracket 10 close to the first roller 40 (i.e., the side different from the first mounting member 401), and a first support groove 403 is provided on the corresponding first roller 40, the support groove 403 is annular, and the support member G is connected to the bottom of the first support groove 403. Similarly, in order to keep the second roller 50 on the mopping bracket 110 stable and not deformed, a support member G is provided on the side of the second bracket 20 close to the second roller 50 (i.e., the side different from the first mounting member 401), and a second support groove 503 is provided on the corresponding second roller 50, the second support groove 503 is annular, and the support member G is connected to the bottom of the second support groove 503. Of course, the support member G can be provided on both the first bracket 10 and the second bracket 20, and the first support groove 403 and the second support groove 503 are provided on the corresponding first roller 40 and the second roller 50, and the support member G can be connected to the bottom of the first support groove 403 and the second support groove 503. The connection here may mean that the support bracket and the bottom of the support groove may have a distance of 0 to 1 mm, or may mean that the support bracket contacts the bottom of the support groove 403 after being subjected to other forces.

[0079] In some other examples, the first roller 40 and the second roller 50 include a metal shaft and a roller cast on the metal shaft, and the annular groove and the roller convex teeth F on the first roller 40 and the second roller 50 are integrally formed by casting to form a roller. The metal shaft (the center axis of the roller) can be driven to rotate, and the first roller 40 and the second roller 50 can rotate around the metal shaft (the center axis of the roller). In some examples, the support groove can be a groove on the roller formed by casting the material on the metal shaft, and the groove is cast by the casting material, and the bottom material of the support groove is the casting material; in some other examples, the support groove can also be a groove formed by casting the material on the metal shaft and the metal shaft, and the bottom material of the support groove is the metal shaft, and the casting material surrounds the metal shaft to form a groove thereon.

[0080] In order to increase the stability of the first roller 40 and the second roller 50 on the mopping bracket 110, P support members G may be provided on one side of the first bracket 10 or / and the second bracket 20 close to the first roller 40, and P annular support grooves 403 are provided on the corresponding first roller 40, and each support member G is connected to the bottom of each support groove 403, wherein P is a positive integer greater than 1. The P support members G may divide the first or second bracket 20 equally.

[0081] Please see Fig.12 In some embodiments, the support member G includes a support rod and an arc-shaped support bracket, and the arc-shaped support bracket is connected to the bottom of the annular support groove 403 on the first roller 40 and / or the second roller 50. The connection here may refer to the support bracket and the bottom of the support groove 403 having a distance of 0 to 1 mm, or may refer to the support bracket contacting the bottom of the support groove 403 after being subjected to other forces. At least part of the support bracket on the support member G is made of a material with a low friction coefficient, so that after the support bracket contacts the bottom of the support groove 403 on the first roller 40 and / or the second roller 50, the support bracket does not affect or reduces the impact on the rotation of the first roller 40 and / or the second roller 50. In some other examples of this embodiment, the arc-shaped support bracket may be a circle, which is sleeved on the support groove 403 to fix the first roller 40 or the second roller 50; the arc-shaped support bracket may also be a semicircle, which just fits the arc of the support groove 403 and fits the support groove 403. The support member G may be fixed to the bracket using screws or strong glue.

[0082] A resisting member H is provided on the first bracket 10 and / or the second bracket 20 at a side different from the supporting member G (i.e., the side of the first mounting member 401 or the second mounting member 501) and at a position corresponding to the supporting member G on the first bracket 10 (see Figure 3), the resisting member H is used to resist the second bracket 20 and / or the first bracket 10. Here, the resisting member H is provided on the side of the first bracket 10 different from the support member G and corresponding to the position of the support member G on the first bracket 10 for introduction - when the first roller 40 is subjected to a force perpendicular to the first roller 40, the force can be transmitted to the first bracket 10 through the support member G on the first bracket 10, and the force can be further transmitted to the second bracket 20 through the resisting member H on the first bracket 10. Similarly, when the first bracket 10 is subjected to a force perpendicular to the first roller 40, the force can be transmitted to the second bracket 20 through the resisting member H. In this way, the first roller 40 or the first bracket 10 can be prevented from being deformed by the force and causing damage to the mop 120. Since the resisting member H is provided on the first bracket and / or the second bracket, the bracket has a support point, and when the first roller and the second roller on the first bracket and / or the second bracket are subjected to the mop binding force, it is not easy to deform, and the mop will not deviate left or right.

[0083] In order to facilitate the installation of the mopping assembly 100 on the cleaning robot, at least one end of the first bracket 10 or the second bracket 20 of the mopping assembly 100 has a telescopic buckle 60 (see Fig.10 ), the mopping assembly 100 can be detachably fixed on the cleaning robot by the telescopic buckle 60. A cavity is provided at at least one end of the first bracket 10 or the second bracket 20, and the telescopic buckle 60 includes an elastic member 601 and a buckle 602. One end of the elastic member 601 is fixed to the bottom of the cavity, and the other end is fixed to the buckle 602. When the elastic member 601 is compressed, the buckle 602 is accommodated in the cavity, and when the elastic member 601 is extended, the buckle 602 is pushed out of the cavity by the elastic member 601. The corresponding cleaning robot has a mopping assembly slot. When the buckle is pressed and the elastic member is compressed, the buckle is accommodated in the cavity. At this time, the mopping assembly 100 can be placed in the mopping assembly slot; when the buckle is released, the elastic member extends, and the buckle is pushed out of the cavity by the elastic member, so that the mopping assembly 100 is relatively fixed in the mopping assembly slot. When the buckle is pressed, the elastic member is compressed, and the buckle can be accommodated in the cavity. At this time, the mopping assembly 100 can be taken out of the mopping assembly slot, so that the mopping assembly 100 can be detachably installed on the cleaning machine. Fig.10 In some examples, in order to prevent the buckle from being completely pushed out of the cavity by the elastic member, a buckle limit 6021 can be set on the buckle 602, and the cavity opened on the corresponding first bracket 10 or the second bracket 20 has a limit window 603. The buckle limit 6021 is placed in the limit window 603 and can move in the limit window as the buckle moves, thereby limiting the buckle from being completely pushed out of the cavity by the elastic member.

[0084] Generally, there are twisted edges 123 on both sides of the mop 120. The twisted edges 123 are formed by interweaving the warp and weft yarns at the edge of the fabric to prevent the yarns at the edge of the fabric from loosening or falling apart during the weaving process of the mop 120. Figure 2 , Figure 3 , Fig.10 In order to prevent the twisted edge 123 of the mop from being worn, both ends of the first bracket 10 and the second bracket 20 on the mopping bracket 110 have receiving grooves 70 , and the receiving grooves 70 are used to receive the twisted edge 123 of the mop 120 .

[0085] The present invention further provides a cleaning robot, which comprises a mopping assembly 100, and the mopping assembly 100 is detachably mounted on the cleaning machine.

[0086] The user can remove the mopping assembly 100, at which time the mopping assembly 100 is in a flat state (the mop 120 is not stretched on the mopping bracket 110), and the user can pull the first bracket 10 and / or the second bracket 20 to rotate around the middle shaft 30, so that the mopping bracket 110 is in a folded state, at which time the mop 120 is not stretched on the mopping bracket 110, and there is a gap between the mopping bracket 110 and the mop 120, so that the mop 120 and the mopping bracket 110 can be separated. After the mop 120 and the mopping bracket 110 are separated, the user can use a new mop 120 to be sleeved on the mopping bracket 110 in the folded state, and the user can pull the first bracket 10 and / or the second bracket 20 to rotate around the middle shaft 30, and the mopping bracket 110 can be switched from the folded state to the flat state, at which time the mop 120 is stretched on the mopping bracket 110, and the user can put the assembled mopping bracket 110 into the mopping assembly slot of the cleaning robot. When the first roller 40 and / or the second roller 50 are driven, the mop cloth 120 will be driven to rotate by the assembled mop bracket 110, and the replaced mop cloth 120 can act on the work surface.

[0087] The present invention also provides a cleaning system, comprising the cleaning robot described above, and a base station connected to the cleaning robot for communication. The base station is a device used in conjunction with the cleaning robot and has multiple functions. Its core purpose is to provide support for the cleaning robot to improve the cleaning efficiency and convenience of the robot. The base station can achieve one or more of the following functions:

[0088] Automatic charging function. When the battery level of the cleaning robot is below a certain threshold, it will use the built-in positioning system to find the location of the base station and automatically return to the base station for charging. The base station has a charging port and a corresponding charging circuit inside, which can provide an adaptive power supply for the cleaning robot. For example, the charging port of some base stations adopts a metal contact design. After the charging contacts at the bottom of the cleaning robot are precisely docked with it, it can be charged, just like a mobile phone placed on a wireless charger.

[0089] Dust collection function. After the cleaning robot completes its cleaning task, it will return to the base station and dump the collected dust, hair and other garbage into the dust collection device of the base station. The dust collection device of the base station has a relatively large capacity, and some can hold weeks or even months of garbage. For example, some high-end base stations use cyclonic dust collection technology, which uses high-speed rotating airflow to suck dust and debris out of the robot's dust box and collect them in the dust bag of the base station. This method can efficiently clean the robot's dust box and reduce the frequency of users dumping garbage.

[0090] Cleaning mop function. For cleaning robots that sweep and mop, the base station can clean the mop at the bottom of the cleaning robot. When the robot returns to the base station, the cleaning system in the base station will start. It usually cleans the mop by spraying water, rotating friction, etc. For example, some base stations are equipped with high-speed rotating cleaning brushes. After the mop is soaked with water, the cleaning brush will be in close contact with the mop and rotate to clean the stains on the mop, and then the sewage will be discharged through the drainage system.

[0091] Drying function. After cleaning the mop, some high-end base stations also have a drying function to prevent bacteria and odor from growing on the mop. The drying function is generally achieved by blowing hot air over the mop. For example, there will be a heating device and a fan inside the base station, and the hot air generated can dry the mop in a short time, leaving it dry and convenient for next use.
