[0052] To further illustrate the principle and structure of the present disclosure, the preferred embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0053] The present disclosure provides a cleaning base station that can be used for automatic cleaning of a cleaning robot, which includes a base station body and a cleaning rotating assembly disposed in a cleaning tank of the cleaning base station. The cleaning rotating assembly can be a turntable, a rotary brush, or other rotating mechanisms for scraping the bottom of the cleaning robot, and the component can be a traveling wheel or a cleaning cloth of the cleaning robot. The cleaning structure of the cleaning base station will be described below by taking the cleaning cloth as an example. In one embodiment, the cleaning rotating assembly is a rotary brush, as Figure 1 and Figure 2 shown, Figure 1 is a three-dimensional schematic diagram of the cleaning base station of the present disclosure at an angle, Figure 2 is a three-dimensional schematic diagram of the cleaning base station of the present disclosure at another angle. The cleaning base station 100 includes a base station body 20 and a rotary brush 10.

[0054] The base station body 20 is generally in the shape of a cuboid. In other embodiments, the base station body 20 can also be designed in the shape of a cylinder, and its external shape can be changed according to the actual application site or aesthetic requirements.

[0055] One side of the base station body 20 is provided with a receiving cavity 26 for receiving the cleaning robot. A cleaning tank 24 is formed at the bottom of the receiving cavity 26 for installing the rotary brush 10 and temporarily storing sewage. The size and dimensions of the cleaning tank 24 can be determined according to the size and dimensions of the cleaning cloth at the bottom of the cleaning robot. A guiding inclined plate 25 is provided at the front of the cleaning tank 24 for guiding the cleaning robot into the receiving cavity 26.

[0056] At the top of the base station body 20, there are a clean water tank 21, a sewage tank 22, and a deep cleaning tank 23 with a cleaning agent. When the cleaning robot is cleaning, it can first be cleaned with the water containing the cleaning agent in the deep cleaning tank 23, and then be cleaned again with the water in the clean water tank 21. The sewage after cleaning is sucked into the sewage tank 22. The number of water tanks at the top of the base station body 20 can be changed according to the requirements of the cleaning degree to meet different cleanliness requirements.

[0057] An inlet 201 is provided on the side of the front of the cleaning tank 24. The clean water tank 21 or the deep cleaning tank 23 is communicated with the inlet 201 through an inlet channel inside the base station body 20, so that the water in the clean water tank 21 or the deep cleaning tank 23 can enter the cleaning tank 24 through the inlet 201. On the other side opposite to the inlet 201, an outlet 202 is provided. The sewage tank 22 is communicated with the outlet 202 through a water suction channel provided inside the base station body 20, so that the sewage after cleaning in the cleaning tank 24 is pumped to the sewage tank 22 by a water pump through the outlet 202.

[0058] The roller brush 10 is arranged in the cleaning tank 24. The roller brush 10 can be arranged along the length direction of the base station body 20 or along the width direction of the base station body 20. The length and number of the roller brush 10 can be changed according to the layout direction of the roller brush 10. For example, if the roller brush 10 is arranged along the length direction of the base station body 20, in order to be able to evenly scrape or dry each position of the cleaning cloth at the bottom of the cleaning robot, the length of the roller brush 10 is approximately equal to the length of the cleaning cloth, and the number of the roller brush 10 can be two. The total width of the two roller brushes 10 in the horizontal direction is also approximately equal to the width of the cleaning cloth. In this way, it can be ensured that each position of the cleaning cloth can be contacted by the roller brush 10 for comprehensive scraping and drying. Another example is that if the roller brush is arranged along the width direction of the base station body 20, the length of the roller brush 10 is shorter and can be approximately equal to the width of the cleaning cloth, and the number of the roller brush 10 can be appropriately increased to ensure that each position of the cleaning cloth can be contacted by the roller brush 10, or the number of the roller brush 10 remains unchanged, and the roller brush 10 moves back and forth along the length direction during rotation. In one embodiment, as Figure 1 shown, there are two roller brushes 10, and the rotation directions of the two roller brushes can be the same. For example, they both rotate clockwise or both rotate counterclockwise. The rotation directions of the two roller brushes can also be relatively rotated in opposite directions. In this way, the wind power generated during the rotation can be simultaneously converged to the middle position between each other, increasing the wind power output.

[0059] An air outlet structure is formed on the roller brush 10. The air outlet structure can be formed by an enclosure wall, and the enclosure wall can be a straight plate, an arc plate, a bent plate formed by splicing arc plates, a bent plate formed by splicing a straight plate and an arc plate, or other plates that can enclose a wall. During the rotation of the roller brush 10, the enclosure wall of the air outlet structure squeezes the air to form an air flow blowing towards the cleaning cloth.

[0060] In one embodiment, the air outlet structure has a wiper blade, the wiper blade has a plurality of air-catching grooves, the groove walls of the air-catching grooves protrude in the radial direction of the roller brush, so that the groove wall of the air-catching groove facing the rotating side of the roller brush forms the surrounding wall of the air outlet structure, and the surrounding wall is an arc-shaped plate or a bent plate capable of forming a groove. When the roller brush rotates, the groove wall of the air-catching groove (i.e., the surrounding wall of the air outlet structure) squeezes the air to form an air flow blowing towards the cleaning cloth, and at the same time, the air flow converged by the air-catching grooves makes the air flow upward along the groove wall, generating an upward wind force to take away the moisture on the cleaning cloth.

[0061] The air outlet structure or the air-catching grooves of the roller brush have various embodiments. Several embodiments are listed below for illustration. This is only an exemplary illustration and not exhaustive.

[0062] The first embodiment of the roller brush

[0063] As Figure 3 and Figure 4 shown, Figure 3 is a schematic structural diagram of the roller brush according to the first embodiment of the present disclosure, Figure 4 and Figure 3 is a partial enlarged view of area A in

[0064] The roller brush 10 includes a roller shaft 11 and a plurality of spaced wiper blades 12 disposed on the outer surface of the roller shaft 11 and extending along the axial direction of the roller shaft 11.

[0065] Among the plurality of wiper blades 12, some wiper blades are flat and some wiper blades are wrinkled. The wrinkled wiper blade 122 includes a wave crest wall 1222 and a wave trough wall 1221 alternately arranged along the axial direction of the roller shaft 11. The wave crest wall 1222 is recessed in one direction (for example, the clockwise direction of the roller shaft 11), enclosing an air-catching groove 1223 relative to the roller shaft 11. The wave trough wall 1221 is recessed in the other opposite direction (for example, the counterclockwise direction of the roller shaft 11), enclosing another air-catching groove 1223 relative to the roller shaft 11. The wave crest wall 1222 and the wave trough wall 1221 are the groove walls of the air-catching groove. The air-catching groove 1223 converges the air flow during the rotation of the roller shaft 11, enhancing the wind force. Thus, after the cleaning cloth is washed, the wind force generated by rotating the roller shaft 11 can dry the cleaning cloth in time, avoiding the generation of peculiar smell and the breeding of bacteria.

[0066] The wave crest wall 1222 and the wave trough wall 1221 form a wavy shape along the axial direction of the roller shaft 11, and the wavy shape conforms to the flow trend of the air flow, making the flow of the air flow smoother and enhancing the wind force.

[0067] The flat-shaped wiper blade 121 is plate-shaped as a whole and can be made of a hard rubber, such as hard silicone. This flat-shaped wiper blade 121 can be used to scrape off the water on the cleaning cloth.

[0068] The flat-shaped wiper blade 121 and the corrugated wiper blade 122 are alternately distributed on the outer peripheral surface of the roller 11. In this way, the rotary brush 10 can scrape off the water on the cleaning cloth through the wiper blade 121 and generate wind to air-dry the cleaning cloth through the wiper blade 122, thereby accelerating the removal of the water on the cleaning cloth and improving the dryness.

[0069] The corrugated wiper blade 122 can be made of a soft rubber, such as soft silicone. The flat-shaped wiper blade 121 and the corrugated wiper blade 122 are alternately arranged, which can reduce the damage to the cleaning cloth during cleaning, and at the same time ensure that the cleaning has sufficient scraping force to ensure the cleaning degree.

[0070] Each wiper blade of the rotary brush 10 can also be used to scrape off the water in the cleaning tank 24. When the wiper blade 12 rotates to a suitable position during the rotation of the roller 11, it can contact the bottom surface of the cleaning tank 24. After the cleaning cloth is washed or the water is scraped off, each wiper blade rotates in the direction of the water outlet 202 to scrape the water in the cleaning tank 24 towards the sewage outlet 202 to remove the water in the cleaning tank 24.

[0071] After the cleaning robot enters the base body 20, the rotary brush 10 rotates slowly at a first speed to scrape the cleaning cloth to remove the stains or stubborn garbage on the cleaning cloth. Since the adhesion of the stains is relatively strong, the first speed of the rotation of the rotary brush 10 should not be too fast. After the cleaning is completed, the rotary brush 10 rotates quickly at a second speed, and the second speed is greater than the first speed, so that the flat-shaped wiper blade 121 can quickly scrape off the water on the cleaning cloth, and the corrugated wiper blade 122 generates wind under the quick rotation of the rotary brush 10 to accelerate the air-drying of the cleaning cloth.

[0072] In one embodiment, the second speed is 2-3 times the first speed.

[0073] The second embodiment of the rotary brush

[0074] As Figure 5 and Figure 6 shown, Figure 5 is a schematic structural diagram of the rotary brush in the second embodiment, Figure 6 is Figure 5 a side schematic diagram. The rotary brush 10b includes a roller 11b and a plurality of spaced wiper blades 12b provided on the outer surface of the roller 11b and extending along the axial direction of the roller 11b.

[0075] Among the multiple wiper blades 12b, some wiper blades are the first wiper blades 121b and some are the second wiper blades 122b. The first wiper blades 121b are sheet-shaped, and the second wiper blades 122b include a plurality of arc-shaped wind-catching walls 120b connected to each other. The arc-shaped wind-catching walls 120b enclose a wind-catching groove 1225b.

[0076] The arc-shaped wind-catching wall 120b includes an arc-shaped wall 1221b extending in the radial direction of the roller 11b and an arched cover wall 1222b bent from the arc-shaped wall 1221b towards the roller 11b. The arched cover wall 1222b is bent towards the direction close to the roller 11b relative to the arc-shaped wall 1221b, that is, the arched cover wall 1222b is inclined forward relative to the arc-shaped wall 1221b, and the bending radian of the arched cover wall 1222b is greater than that of the arc-shaped wall 1221b to enhance the air flow convergence ability of the wind-catching groove 1225b, that is, the wind-catching ability, and enhance the wind force.

[0077] The bending radians of both the arc-shaped wall 1221b and the arched cover wall 1222b are less than π, so as to avoid too large a radian from blocking the air flow and further increase the wind force.

[0078] Two adjacent arc-shaped wind-catching walls 120b are connected by an arc-shaped transition wall 1220b to make the air flow smoother.

[0079] The arc length of the arc-shaped transition wall 1220b is less than that of the arc-shaped wind-catching wall 120b to increase the area of the arc-shaped wind-catching wall 120b within a limited space and increase the wind-catching ability.

[0080] The arc-shaped transition wall 1220b includes a first arc segment 1224b connecting two adjacent arc-shaped walls 1221b and a second arc segment 1223b connecting two adjacent arched cover walls 1222b. The bending direction of the first arc segment 1224b is opposite to that of the arc-shaped wall 1221b, and the bending direction of the second arc segment 1223b is opposite to that of the arched cover wall 1222b, and the bending radian of the second arc segment 1223b is greater than that of the first arc segment, so that the arc-shaped wall 1221b forms two connecting walls with different radian to transition with the arc-shaped wall 1221b and the arched cover wall 1222b of the arc-shaped wind-catching wall 120b respectively, thus forming a smoother curve transition surface and allowing the air flow to pass through more smoothly.

[0081] The first wiper blade 121b is integrally plate-shaped and can be made of a hard glue, such as hard silicone. The first wiper blade 121b can be used to scrape off the moisture on the cleaning cloth.

[0082] The first wiper blades 121b and the second wiper blades 122b are alternately distributed on the outer peripheral surface of the roller 11b. In this way, the roller brush 10b can scrape off the moisture on the cleaning cloth through the first wiper blades 121b and generate wind force through the second wiper blades 122b to air-dry the cleaning cloth, thereby accelerating the drying of the cleaning cloth and improving the dryness.

[0083] As Figure 5 shown, from the side view, the first wiper blade 121b and the second wiper blade 122b are radially distributed relative to the roller 11b, and the bending directions of the second wiper blades 122b are the same direction, for example, all in the counterclockwise direction.

[0084] The working mode of this roller brush 10b is similar to that of the first embodiment, and will not be elaborated again here.

[0085] The third embodiment of the roller brush

[0086] As Figure 7 and Figure 8 shown, Figure 7 FIG. is a schematic structural diagram of the roller brush in the third embodiment, Figure 8 is Figure 7 a side schematic view of. The roller brush 10c includes a roller 11c and a plurality of spaced wiper blades 12c provided on the outer surface of the roller 11c and extending along the axial direction of the roller 11c.

[0087] Among the plurality of wiper blades 12c, some wiper blades are the first wiper blades 121c, and some wiper blades are the second wiper blades 122c. The structure and function of the second wiper blade 122c are the same as those of the second wiper blade 122b in the second embodiment, and will not be elaborated one by one here.

[0088] The first wiper blade 121c includes a flat plate portion 1211c extending along the axial direction of the roller 11c and an arc portion 1212c bent from the flat plate portion 1211c towards the roller 11c. The bending direction of the arc portion 1212c is the same as the bending direction of the arched cover wall 1222c of the second wiper blade 122c, that is, if the arched cover wall 1222c of the second wiper blade 122c is bent counterclockwise, then the arc portion 1212c is also bent counterclockwise. Thus, the cross-section of this roller brush 10c is in the shape of a propeller, enhancing the wind force.

[0089] The fourth embodiment of the roller brush

[0090] As Figure 9 and Figure 10 shown, Figure 9 FIG. is a schematic structural diagram of the roller brush in the fourth embodiment, Figure 10 is Figure 9 a side schematic view of. The roller brush 10d includes a roller 11d and a plurality of spaced wiper blades 12d provided on the outer surface of the roller 11d and extending along the axial direction of the roller 11d.

[0091] Among the plurality of wiper blades 12d, some wiper blades are the first wiper blades 121d, and some wiper blades are the second wiper blades 122d.

[0092] The second wiper blade 122d includes a plurality of arc-shaped wind-catching walls 120d connected to each other, and the arc-shaped wind-catching walls 120d enclose a wind-catching groove 1225d.

[0093] The arc-shaped wind-catching wall 120d includes an arc-shaped wall 1221d extending in the radial direction of the roller 11d and an arched cover wall 1222d bent from the arc-shaped wall 1221d towards the roller 11d. The arched cover wall 1222d is bent towards the roller 11d relative to the arc-shaped wall 1221d, that is, the arched cover wall 1222d is tilted forward relative to the arc-shaped wall 1221d, and the bending radian of the arched cover wall 1222d is greater than that of the arc-shaped wall 1221d to enhance the air flow convergence ability of the wind-catching groove 1225d, that is, the wind-catching ability, and enhance the wind force.

[0094] The bending radians of the arc-shaped wall 1221d and the arched cover wall 1222d are less than π, so as to avoid excessive radians from blocking the air flow and further increase the wind force.

[0095] Two adjacent arc-shaped wind-catching walls 120b are directly connected without a transition surface therebetween.

[0096] The first wiper 121d includes a flat plate portion 1211d extending along the axial direction of the roller 11d and an arc portion 1212d bent from the flat plate portion 1211d towards the roller 11d. The bending direction of the arc portion 1212d is the same as the bending direction of the arched cover wall 1222d of the second wiper 122d. In this way, the cross-section of the rotary brush 10d is in the shape of a propeller, enhancing the wind force.

[0097] The fifth embodiment of the rotary brush

[0098] As Figure 11 and Figure 12 shown, Figure 11 FIG. is a schematic structural diagram of the rotary brush in the fifth embodiment, Figure 12 is Figure 11 a side schematic diagram of. The rotary brush 10e includes a roller 11e and a plurality of spaced wipers 12e arranged on the outer surface of the roller 11e and extending along the axial direction of the roller 11e.

[0099] The wiper 12e is an arc-shaped plate, and the bending radian of the arc-shaped plate is less than π, so as to avoid excessive radians from blocking the air flow and further increase the wind force. The arc-shaped plate forms a wind-catching groove 125e, and the groove wall of the wind-catching groove (i.e., the arc-shaped plate) extends in the radial direction of the roller 11e to form a radial air outlet structure. When the rotary brush 10e rotates, the groove wall of the wind-catching groove squeezes the air to form a directional air flow. The wind-catching groove 125e converges the air flow and makes the air flow upward along the groove wall, generating an upward wind force to take away the moisture on the cleaning cloth.

[0100] Looking at the cross-section of the rotary brush 10e, the arc-shaped plates are radially distributed around the roller 11e, and the bending directions of the arc-shaped plates are the same, that is, the centers of the arcs of the arc-shaped plates are on the same side. For example, they are all bent counterclockwise. The cross-sectional shape of the rotary brush 10e is in the shape of a propeller to enhance the wind force.

[0101] The sixth embodiment of the rotary brush

[0102] As Figure 13 and Figure 14 shown, Figure 13 FIG. is a schematic structural diagram of the rotary brush in the sixth embodiment, Figure 14 is Figure 13 a side schematic diagram. The rotary brush 10f includes a roller 11f and a plurality of spaced blades 12f provided on the outer surface of the roller 11f and extending along the axial direction of the roller 11f.

[0103] Each blade 12f is a corrugated plate. In this way, it is closer to the direction and trend of the airflow, making the airflow more smooth during the rotation of the rotary brush 10f, thereby enhancing the wind force. The corrugated plates are radially distributed around the roller 12f. The blade 12f includes alternately distributed peak portions 121f and valley portions 122f, and both the peak portions 121f and the valley portions 122f enclose a wind-catching groove 125f. The groove wall of the wind-catching groove 125f (i.e., the corrugated plate) extends along the radial direction of the roller 11e. When the rotary brush 10e rotates, the corrugated plate squeezes the air to form a directional airflow, and a plurality of air outlet structures converge the airflow and make the airflow flow upward along the groove wall, generating an upward wind force to take away the moisture on the cleaning cloth.

[0104] The radian of both the peak portion 121f and the valley portion 122f is less than π, so as to avoid excessive radian blocking the flow of the airflow and further increasing the wind force.

[0107] One end of the rotary brush 10g is connected to the air duct 15g through the joint 14g, and the air duct 15g is connected to the blower. The blower is arranged inside the base body 10 and blows air into the air cavity 111g of the rotary brush 10g through the air duct 15g. The air flow flows out from each air outlet hole 13g through the air cavity 111g and flows upward to the cleaning cloth to air-dry the cleaning cloth.

[0108] The above is an exemplary embodiment of the rotary brush forming an air flow to air-dry the cleaning cloth. Any equivalent changes made by applying the present disclosure specification and drawings, such that the rotary brush forms an air flow to air-dry the cleaning cloth, are within the protection scope of the present disclosure.

[0109] The present disclosure further provides a cleaning system, as Figure 16 shown, Figure 16 is a schematic structural diagram of the cleaning system of the present disclosure. The cleaning system 1 includes the above-mentioned cleaning base station 100 and the cleaning robot 300. The outer shape of the cleaning base station 100 can be changed to a cylindrical shape. The cleaning robot 300 includes a robot body 31 and a cleaning cloth 32 arranged at the bottom of the robot body 31. The cleaning robot 30 enters the accommodation cavity 26 of the cleaning base station 100 through the guiding inclined plate 25. When the cleaning robot 300 docks at the cleaning base station 100, the cleaning cloth 32 covers the cleaning rotating assembly, and the cleaning rotating assembly can be any one of the rotary brushes in the above embodiments.

[0110] During operation, the rotary brush first brushes off the stains on the cleaning cloth 32, and after the cleaning is completed, the rotary brush blows air to air-dry the cleaning cloth 32.

[0111] In one embodiment, the rotary brush rotates at a first speed to brush off the stains on the cleaning cloth and rotates at a second speed to air-dry the cleaning cloth 32, wherein the second speed is greater than the first speed.

[0112] In one embodiment, the second speed is 2 - 3 times the first speed. Of course, in other embodiments, the second speed is any value greater than the first speed, such as the second speed is 1.1 times, 1.5 times, 4 times or 5 times the first speed, etc.

[0113] The above is only a preferred and feasible embodiment of the present disclosure, and does not limit the protection scope of the present disclosure. Any equivalent structural changes made by using the content of the present disclosure specification and drawings are included in the protection scope of the present disclosure.
