[0046] In order to further illustrate the principle and structure of the present disclosure, preferred embodiments of the present disclosure are now described in detail with reference to the accompanying drawings.

[0047] The present disclosure provides a cleaning base station that can be used for automatic cleaning by a cleaning robot, which includes a base station body and a cleaning rotating assembly arranged in a cleaning tank of the cleaning base station. The cleaning rotating assembly can be a rotating mechanism of a turntable, a roller brush or other parts for scraping the bottom of the cleaning robot. The parts can be the walking wheels or cleaning cloth of the cleaning robot. The cleaning structure of the cleaning base station is described below using a cleaning cloth as an example. In one embodiment, the cleaning rotating assembly is a roller brush, such as Figure 1 and Figure 2 As shown, Figure 1 It is a three-dimensional schematic diagram of the cleaning base station disclosed in the present invention at an angle. Figure 2 The cleaning base station 100 of the present invention is a three-dimensional schematic diagram at another angle. The cleaning base station 100 includes a base station body 20 and a roller brush 10 .

[0048] The base station body 20 is roughly in the shape of a cuboid. In other embodiments, the base station body 20 can also be designed to be in the shape of a cylinder. Its shape can be changed according to the actual application location or aesthetic requirements.

[0049] A receiving chamber 26 is provided on one side of the base station body 20 for receiving the cleaning robot. A cleaning groove 24 is formed at the bottom of the receiving chamber 26 for installing the roller brush 10 and temporarily storing sewage. The size and dimensions of the cleaning groove 24 can be determined according to the size and dimensions of the cleaning cloth at the bottom of the cleaning robot. A guide inclined plate 25 is provided at the front of the cleaning groove 24 for guiding the cleaning robot into the receiving chamber 26.

[0050] The top of the base station body 20 is provided with a clean water tank 21, a dirty water tank 22 and a deep cleaning tank 23 with a detergent. When the cleaning robot cleans, it can first be cleaned with the water containing the detergent in the deep cleaning tank 23, and then cleaned again with the water in the clean water tank 21, and the dirty water after cleaning is sucked into the dirty water tank 22. The number of water tanks on the top of the base station body 20 can be changed according to the requirements of the cleaning degree to meet different cleanliness requirements.

[0051] A water inlet 201 is provided on the side in front of the cleaning tank 24, and the clean water tank 21 or the deep cleaning tank 23 is connected to the water inlet 201 through the water 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 water inlet 201. A water outlet 202 is provided on the other side opposite to the water inlet 201, and the sewage tank 22 is connected to the water outlet 202 through the water suction channel provided inside the base station body 20, so that the sewage cleaned in the cleaning tank 24 is pumped into the sewage tank 22 through the water outlet 202 by the water pump.

[0052] The roller brush 10 is arranged in the cleaning groove 24, and the roller brush 10 can be arranged along the length direction of the base station body 20, or along the transverse 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, the roller brush 10 is arranged along the length direction of the base station body 20. In order 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 roughly equal to the length of the cleaning cloth, and the number of roller brushes 10 can be two, and the total width of the two roller brushes 10 in the transverse direction is also roughly 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, so as to facilitate comprehensive scraping and drying. For another example, 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, which can be roughly equal to the width of the cleaning cloth, and the number of roller brushes 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 roller brushes 10 remains unchanged, and the roller brush 10 moves back and forth along the length direction during rotation. In one embodiment, if Figure 1 As shown, there are two roller brushes 10, and the rotation directions of the two roller brushes can be the same, for example, both rotate clockwise or both rotate counterclockwise. The rotation directions of the two roller brushes can also rotate relative to each other in opposite directions, so that the wind force generated during the rotation process can be simultaneously gathered to the middle position of each other, thereby increasing the wind output.

[0053] The roller brush 10 is provided with an air outlet structure, which can be formed by a surrounding wall, which can be a straight plate, an arc plate, a curved plate formed by arc plates, a bent plate formed by straight plates and arc plates, or other plates that can form a wall. When the roller brush 10 rotates, the surrounding wall of the air outlet structure squeezes the air to form an airflow that blows toward the cleaning cloth.

[0054] In one embodiment, the roller brush has a scraper blade, and the scraper blade has a plurality of air vents, and the groove wall of the air vent protrudes in the radial direction of the roller brush, that is, the groove wall of the air vent facing the rotating side of the roller brush forms the surrounding wall of the air outlet structure, and the surrounding wall is an arc plate or a curved plate that can form a groove. When the roller brush rotates, the groove wall of the air vent (that is, the surrounding wall of the air outlet structure) squeezes the air to form an airflow blowing toward the cleaning cloth, and at the same time, the air vent converges the formed airflow and makes the airflow flow upward along the groove wall, generating an upward wind force to take away the moisture on the cleaning cloth.

[0055] The air outlet structure or the air venting groove of the roller brush 10 has various implementations, and several implementations are listed below for illustration, which are merely exemplary and not exhaustive.

[0056] First embodiment of the roller brush

[0057] like Figure 3 and Figure 4 As shown, Figure 3 is a schematic structural diagram of a roller brush according to a first embodiment of the present disclosure, Figure 4 for Figure 3 The roller brush 10 comprises a roller 11 and a plurality of spaced scrapers 12 which are arranged on the outer surface of the roller 11 and extend axially along the roller 11 .

[0058] Among the multiple scrapers 12, some scrapers are flat and some are wrinkled. The wrinkled scraper 122 includes a crest wall 1222 and a trough wall 1221 alternately arranged along the axial direction of the roller 11. The crest wall 1222 is recessed in one direction (for example, the clockwise direction of the roller 11) to form a ventilation groove 1223 relative to the roller 11. The trough wall 1221 is recessed in another opposite direction (for example, the counterclockwise direction of the roller 11) to form another ventilation groove 1223 relative to the roller 11. The crest wall 1222 and the trough wall 1221 are the groove walls of the ventilation groove. The ventilation groove 1223 gathers airflow during the rotation of the roller 11 to enhance wind force. In this way, after the cleaning cloth is cleaned, the wind force generated by the rotating roller 11 can dry the cleaning cloth in time to avoid the generation of odor and the breeding of bacteria.

[0059] The wave crest wall 1222 and the wave trough wall 1221 form a wave shape along the axial direction of the roller 11 , and the wave shape conforms to the flow trend of the airflow, making the airflow flow smoother and enhancing the wind force.

[0060] The crest wall 1222 and the trough wall 1221 are arc-shaped, and the curvature a of the crest wall 1222 and the trough wall 1221 is smaller than π, so that the excessive curvature can be prevented from blocking the flow of airflow, thereby increasing the wind force.

[0061] The flat scraper blade 121 is in the shape of a plate as a whole and can be made of hard rubber, such as hard silica gel. The flat scraper blade 121 can be used to scrape off the moisture on the cleaning cloth.

[0062] The flat scraper blade 121 and the pleated scraper blade 122 are alternately distributed on the outer peripheral surface of the roller 11, so that the roller brush 10 can scrape the moisture on the cleaning cloth through the scraper blade 121 and generate wind to dry the cleaning cloth through the scraper blade 122, thereby accelerating the removal of moisture from the cleaning cloth and improving the dryness.

[0063] The pleated scraper blade 122 can be made of soft glue, such as soft silica gel. The flat scraper blade 121 and the pleated scraper blade 122 are arranged alternately, which can reduce the damage to the cleaning cloth during cleaning, and also ensure that the cleaning has sufficient scraping force to ensure the cleanliness.

[0064] The scrapers of the roller brush 10 can also be used to scrape off the moisture in the cleaning tank 24. When the roller 11 rotates to a suitable position, the scraper 12 can contact the bottom surface of the cleaning tank 24. After the cleaning cloth has finished cleaning or scraping the water, the scrapers rotate toward the water outlet 202 to scrape the moisture in the cleaning tank 24 toward the sewage outlet 202 to remove the moisture in the cleaning tank 24.

[0065] After the cleaning robot enters the base station body 20, the roller brush 10 rotates slowly at a first speed to scrape the cleaning cloth to remove stains or stubborn garbage on the cleaning cloth. Since the stains have strong adhesion, the first speed of the roller brush 10 should not be too fast. After the cleaning is completed, the roller brush 10 rotates quickly at a second speed, which is greater than the first speed, so that the flat scraper 121 can quickly scrape off the moisture on the cleaning cloth, and the wrinkled scraper 122 can blow air under the rapid rotation of the roller brush 10 to speed up the drying of the cleaning cloth.

[0066] The base station body 20 is provided with a motor and a control circuit board, the motor is electrically connected to the control circuit board, and the motor is connected to the roller brush 10 to drive the roller brush 10 to rotate. The control circuit board controls the rotation speed and rotation direction of the motor, thereby controlling the rotation speed and rotation direction of the roller brush 10.

[0067] The rotation speed of the roller brush 10 and its cleaning time and air-drying time can be factory default settings or can be set by the user through a terminal device such as a mobile phone or a computer. The cleaning time refers to the time for cleaning the cleaning cloth when the roller brush rotates at the first speed; the air-drying time refers to the time for scraping and air-drying the cleaning cloth when the roller brush rotates at the second speed.

[0068] 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. The roller brush of the present disclosure rotates at different speeds, so that the roller brush can not only fully scrape the cleaning cloth at the first speed to remove stubborn stains and garbage, but also quickly scrape off moisture and quickly blow air to dry the cleaning cloth at the second speed. In this way, the cleaning cloth can not only be fully cleaned, but also the moisture of the cleaning cloth can be quickly removed, thereby improving the cleaning efficiency and drying efficiency, avoiding the generation of odor, and reducing the growth of bacteria.

[0069] Second embodiment of the roller brush

[0070] like Figure 5 and Figure 6 As shown, Figure 5 is a schematic diagram of the structure of the roller brush in the second embodiment, Figure 6 for Figure 5 The roller brush 10b includes a roller shaft 11b and a plurality of spaced scrapers 12b disposed on the outer surface of the roller shaft 11b and extending axially along the roller shaft 11b.

[0071] Among the multiple scraper blades 12b, some of the scraper blades are first scraper blades 121b, and some of the scraper blades are second scraper blades 122b. The first scraper blade 121b is in sheet shape, and the second scraper blade 122b includes a plurality of arcuate wind-driving walls 120b connected to each other, and the arcuate wind-driving walls 120b form a wind-driving groove 1225b.

[0072] The arc-shaped wind-shaking 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 toward the roller 11b. The arched cover wall 1222b is bent relative to the arc-shaped wall 1221b toward the roller 11b, that is, the arched cover wall 1222b is inclined forward relative to the arc-shaped wall 1221b, and the curvature of the arched cover wall 1222b is greater than the curvature of the arc-shaped wall 1221b, so as to enhance the airflow convergence capability of the wind-shaking groove 1225b, that is, the wind-shaking capability, and enhance the wind force.

[0073] The curvature of the curved wall 1221b and the arched cover wall 1222b are both smaller than π, so as to avoid the excessive curvature blocking the flow of airflow, thereby increasing the wind force.

[0074] Two adjacent arc-shaped ventilation walls 120b are connected by an arc-shaped transition wall 1220b to make the air flow smoother.

[0075] The arc length of the arc-shaped transition wall 1220b is smaller than the arc length of the arc-shaped ventilating wall 120b, so as to increase the area of ​​the arc-shaped ventilating wall 120b within a limited space, thereby increasing the ventilating capacity.

[0076] 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 arch-shaped 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 arch-shaped cover wall 1222b, and the bending curvature 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 curvatures, which respectively transition with the arc-shaped wall 1221b and the arch-shaped cover wall 1222b of the arc-shaped ventilation wall 120b, thereby forming a smoother curved transition surface, and the airflow passes more smoothly.

[0077] The first scraper blade 121b is in the shape of a plate and can be made of hard rubber, such as hard silica gel. The first scraper blade 121b can be used to scrape off the moisture on the cleaning cloth.

[0078] The first scraper blade 121b and the second scraper blade 122b are alternately distributed on the outer circumference of the roller 11b, so that the roller brush 10b can scrape the moisture on the cleaning cloth through the first scraper blade 121b and generate wind to dry the cleaning cloth through the second scraper blade 122b, thereby accelerating the drying of the cleaning cloth and improving the dryness.

[0079] like Figure 5 As shown, from a side angle, the first scraper blades 121b and the second scraper blades 122b are radially distributed relative to the roller 11b, and the bending direction of each second scraper blade 122b is the same direction, for example, all are counterclockwise.

[0080] After the cleaning robot enters the base station body 20, the roller brush 10b rotates slowly at a first speed to fully scrape the cleaning cloth to remove stains or stubborn garbage on the cleaning cloth. After the cleaning is completed, the roller brush 10b rotates rapidly at a second speed, which is greater than the first speed, so that the first scraper 121b quickly scrapes off the moisture on the cleaning cloth, and the second scraper 122b increases the wind force under the rapid rotation of the roller brush 10b to accelerate the drying of the cleaning cloth.

[0081] The third embodiment of the roller brush

[0082] like Figure 7 and Figure 8 As shown, Figure 7 is a schematic diagram of the structure of the roller brush in the third embodiment, Figure 8 for Figure 7 The roller brush 10c includes a roller shaft 11c and a plurality of spaced scrapers 12c disposed on the outer surface of the roller shaft 11c and extending axially along the roller shaft 11c.

[0083] Among the plurality of scrapers 12c, some scrapers are first scrapers 121c, and some scrapers are second scrapers 122c. The structure and function of the second scraper 122c are the same as those of the second scraper 122b in the second embodiment, and will not be described in detail here.

[0084] The first scraper blade 121c includes a flat plate portion 1211c extending axially along the roller shaft 11c and an arc portion 1212c bent from the flat plate portion 1211c toward the roller shaft 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 scraper blade 122c, that is, if the arched cover wall 1222c of the second scraper blade 122c is bent counterclockwise, the arc portion 1212c is also bent counterclockwise, so that the cross section of the roller brush 10c is propeller-shaped, which enhances the wind force.

[0085] After the cleaning robot enters the base station body 20, the roller brush 10c rotates slowly at a first speed to fully scrape the cleaning cloth to remove stains or stubborn garbage on the cleaning cloth. After the cleaning is completed, the roller brush 10c rotates rapidly at a second speed, which is greater than the first speed, so that the first scraper 121c quickly scrapes away the moisture on the cleaning cloth, and the second scraper 122c increases the wind force under the rapid rotation of the roller brush 10c to accelerate the drying of the cleaning cloth.

[0086] Fourth embodiment of the roller brush

[0087] like Fig. 9 and Fig.10 As shown, Fig. 9 is a schematic diagram of the structure of the roller brush in the fourth embodiment, Fig.10 for Fig. 9 The roller brush 10d includes a roller shaft 11d and a plurality of spaced scrapers 12d disposed on the outer surface of the roller shaft 11d and extending axially along the roller shaft 11d.

[0088] Among the plurality of scraper blades 12d, some scraper blades are first scraper blades 121d, and some scraper blades are second scraper blades 122d.

[0089] The second scraper blade 122d includes a plurality of arc-shaped ventilation walls 120d connected to each other, and the arc-shaped ventilation walls 120d form a ventilation groove 1225d.

[0090] The arc-shaped wind-shaking 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 toward the roller 11d. The arched cover wall 1222d is bent relative to the arc-shaped wall 1221d toward the roller 11d, that is, the arched cover wall 1222d is inclined forward relative to the arc-shaped wall 1221d, and the curvature of the arched cover wall 1222d is greater than the curvature of the arc-shaped wall 1221d, so as to enhance the airflow convergence capability of the wind-shaking groove 1225d, that is, the wind-shaking capability, and enhance the wind force.

[0091] The curvature of the curved wall 1221d and the arched cover wall 1222d is less than π, so as to avoid the excessive curvature blocking the flow of airflow, thereby increasing the wind force.

[0092] Two adjacent arc-shaped ventilation walls 120b are directly connected, and no transition surface is provided between them.

[0093] The first scraper blade 121d includes a flat plate portion 1211d extending axially along the roller shaft 11d and an arc portion 1212d bent from the flat plate portion 1211d toward the roller shaft 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 scraper blade 122d, so that the cross section of the roller brush 10d is propeller-shaped to enhance wind force.

[0094] After the cleaning robot enters the base station body 20, the roller brush 10d rotates slowly at a first speed to fully scrape the cleaning cloth to remove stains or stubborn garbage on the cleaning cloth. After the cleaning is completed, the roller brush 10d rotates rapidly at a second speed, which is greater than the first speed, so that the first scraper 121d can quickly scrape the moisture on the cleaning cloth, and the second scraper 122d increases the wind force under the rapid rotation of the roller brush 10d to speed up the drying of the cleaning cloth.

[0095] Fifth embodiment of the roller brush

[0096] like Fig.11 and Fig.12 As shown, Fig.11 is a schematic diagram of the structure of the roller brush in the fifth embodiment, Fig.12 for Fig.11 The roller brush 10e includes a roller shaft 11e and a plurality of spaced scrapers 12e disposed on the outer surface of the roller shaft 11e and extending axially along the roller shaft 11e.

[0097] The scraper 12e is an arc-shaped plate, and the curvature of the arc-shaped plate is less than π, so that the curvature can avoid blocking the flow of airflow due to excessive curvature, thereby increasing the wind force. The arc-shaped plate forms a ventilation groove 125e, and the groove wall of the ventilation 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 roller brush 10e rotates, the arc-shaped plate squeezes the air to form an airflow, and the ventilation groove 125e gathers the airflow and makes the airflow flow upward along the groove wall, generating an upward wind force to take away the moisture on the cleaning cloth.

[0098] From the cross section of the roller brush 10e, the arc plates are radially distributed with the roller shaft 11e as the center, and the bending directions of the arc plates are the same, that is, the arc centers of the arc plates are located on the same side, for example, all bend in the counterclockwise direction. The cross section of the roller brush 10e is propeller-shaped to enhance wind force.

[0099] After the cleaning robot enters the base station body 20, the roller brush 10e rotates slowly at a first speed to fully scrape the cleaning cloth to remove stains or stubborn garbage on the cleaning cloth. After the cleaning is completed, the roller brush 10e rotates rapidly at a second speed, which is greater than the first speed, so that the scraper 12e increases the wind force under the rapid rotation of the roller brush 10e, thereby accelerating the drying of the cleaning cloth.

[0100] Sixth embodiment of the roller brush

[0101] like Fig.13 and Fig.14 As shown, Fig.13 is a schematic diagram of the structure of the roller brush in the sixth embodiment, Fig.14 for Fig.13 The roller brush 10f includes a roller shaft 11f and a plurality of spaced scrapers 12f disposed on the outer surface of the roller shaft 11f and extending axially along the roller shaft 11f.

[0102] Each scraper blade 12f is a corrugated plate, which is closer to the direction and trend of the air flow, so that the air flow of the roller brush 10f during the rotation process is smoother, thereby enhancing the wind force. Each corrugated plate is radially distributed with the roller 12f as the center. The scraper blade 12f includes alternating peaks 121f and troughs 122f, and the peaks 121f and the troughs 122f are both surrounded by a ventilation groove 125f. The groove wall of the ventilation groove 125f (i.e., the corrugated plate) extends along the radial direction of the roller 11e. When the roller brush 10e rotates, the corrugated plate squeezes the air to form an airflow. The multiple ventilation grooves 125f 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.

[0103] The curvature of the crest portion 121f and the trough portion 122f are both smaller than π, so as to avoid the excessive curvature blocking the flow of airflow, thereby increasing the wind force.

[0104] After the cleaning robot enters the base station body 20, the roller brush 10f rotates slowly at a first speed to fully scrape the cleaning cloth to remove stains or stubborn garbage on the cleaning cloth. After the cleaning is completed, the roller brush 10f rotates rapidly at a second speed, which is greater than the first speed, so that the scraper 12f increases the wind force under the rapid rotation of the roller brush 10f, thereby accelerating the drying of the cleaning cloth.

[0105] Seventh embodiment of the roller brush

[0106] In the above-mentioned embodiments 1 to 6, the roller brush has a vent groove formed thereon and realizes air discharge by rotating. In this embodiment, the air discharge of the roller brush can be realized by a fan, and the air discharge structure on the roller brush can be an air outlet. Fig.15 As shown, Fig.15Schematic diagram of the structure of the roller brush in the seventh embodiment. The roller brush 10g includes a roller 11g and a plurality of spaced scrapers 12g (only one scraper is shown in the figure) disposed on the outer surface of the roller 11g and extending axially along the roller 11g. An air cavity 111g extending axially along the roller 11g is formed inside the roller 11g, and a plurality of air outlet holes 13g communicating with the air cavity 111g are disposed on the roller 11g and located between two adjacent scrapers 12g, i.e., an air outlet structure.

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

[0108] The above is an exemplary embodiment of a roller brush forming an airflow to dry a cleaning cloth. Any equivalent changes made by applying the specification and drawings of this disclosure so that a roller brush forms an airflow to dry a cleaning cloth shall fall within the protection scope of this disclosure.

[0109] The present disclosure further provides a cleaning system, such as Fig.16 As shown, Fig.16 Schematic diagram of the structure of the cleaning system disclosed in the present invention. The cleaning system 1 includes the above-mentioned cleaning base station 100 and a 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 accommodating cavity 26 of the cleaning base station 100 through the guide inclined plate 25. When the cleaning robot 300 is docked at the cleaning base station 100, the cleaning cloth 32 covers the cleaning rotating assembly, and the cleaning rotating assembly can be any roller brush in the above-mentioned embodiments.

[0110] During operation, the roller brush first removes the stains on the cleaning cloth 32 , and after the cleaning is completed, the roller brush blows out air to dry the cleaning cloth 32 .

[0111] In one embodiment, the roller brush rotates at a first speed to remove stains on the cleaning cloth, and rotates at a second speed to quickly scrape off moisture or quickly blow air to 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 implementations, 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.

[0113] The above are only preferred feasible embodiments of the present disclosure and are not intended to limit the protection scope of the present disclosure. All equivalent structural changes made using the contents of the present disclosure and the drawings are included in the protection scope of the present disclosure.
