Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a base station for a floor sweeping robot and a cleaning system. Background Art

[0002] The base station for a floor sweeping robot is used for operations such as the automatic return of the floor sweeping robot for charging and the cleaning of the mop. Currently, the alignment during the return charging of the floor sweeping robot is basically achieved by guiding lights or other sensors. When the floor sweeping robot searches for the charging pile for automatic charging, due to factors such as sensor accuracy, algorithm limitations, or environmental interference, the alignment may be inaccurate, and it is impossible to accurately dock with the charging pile or there is an error during alignment, resulting in poor contact between the charging contacts, which affects the charging efficiency; moreover, the surface of the charging contact spring piece is prone to oxidation when encountering water or water vapor, and if the position is slightly off, it will cause poor contact and inability to charge, with a low error tolerance.

[0003] In view of this, the purpose of the utility model is to provide a new technical solution to solve the existing technical problems. Content of the Utility Model

[0049] The following is combined with Figures 1-14 The utility model is further described.

[0050] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0051] Reference Figures 1 to 3, the present utility model provides a base station for a floor sweeping robot, which is used to improve the accuracy and fault tolerance rate of the floor sweeping robot when docking with the base station for charging, thereby reducing the problem of charging failure caused by poor contact. The base station for the floor sweeping robot is used in conjunction with the floor sweeping robot. The floor sweeping robot is a prior art and includes conventional structures such as driving wheels and charging contacts, so the specific structure and working principle of the floor sweeping robot will not be described in detail here. The base station for the floor sweeping robot includes a tray main body 2 and a connector assembly 7. Among them, the tray main body 2 is the base of the base station for the floor sweeping robot. The tray main body 2 has a laterally open receiving cavity. Generally, functional components for charging, adding cleaning liquid, and cleaning garbage are arranged in the receiving cavity. During operation, the floor sweeping robot enters the receiving cavity to dock with these functional components for charging, cleaning, and other operations; the tray main body 2 is inclined with a climbing surface 21, and the climbing surface 21 is used to guide at least part of the floor sweeping robot into the receiving cavity for charging, cleaning, and other operations. The connector assembly 7 is arranged on the tray main body 2 and is located in the receiving cavity. When the floor sweeping robot enters the receiving cavity and the charging contact of the floor sweeping robot contacts and conducts with the connector assembly 7, the floor sweeping robot can be charged. The connector assembly 7 is movably arranged on the tray main body 2. The connector assembly 7 includes a charging elastic piece 71 and an elastic piece bracket 72, and the elastic piece bracket 72 is fixedly connected to the tray main body 2. When the floor sweeping robot enters the receiving cavity for charging, if the floor sweeping robot fails to return to the charging position accurately, that is, there is an alignment error between the charging contact of the floor sweeping robot and the charging elastic piece 71, since the connector assembly 7 and the tray main body 2 can be deflected, the charging elastic piece 71 will automatically adjust the deflection angle when contacting the charging contact of the floor sweeping robot to ensure that the charging contact of the floor sweeping robot can accurately contact and conduct with the charging elastic piece 71, thereby improving the accuracy and fault tolerance rate of the return charging.

[0052] Referring to Figure 2 and Figure 3 , further, the elastic piece bracket 72 includes a bracket front end 721 and a bracket tail end 722, and the bracket front end 721 and the bracket tail end 722 are sequentially connected to form the overall elastic piece bracket 72. The charging elastic piece 71 is installed on the side of the bracket front end 721 facing away from the bracket tail end 722, and the bracket front end 721 is floatingly connected to the bracket tail end 722. When the floor sweeping robot returns to the charging position for alignment, the bracket front end 721 is subjected to the force of the floor sweeping robot, and the relative position between the bracket front end 721 and the floor sweeping robot is finely adjusted up, down, left, and right, so that the charging elastic piece 71 is aligned with the charging contact of the floor sweeping robot for contact, so as to facilitate the charging operation. The surface of the charging elastic piece 71 is provided with charging protrusions, which contact and conduct with the charging contacts of the floor sweeping robot during charging. In this embodiment, a pin 711 is fixedly connected to the charging elastic piece 71, and a hole groove is opened on the pin 711. A buckle position matching the hole groove is arranged on the inner wall of the bracket front end 721. During installation, the pin 711 of the charging elastic piece 71 is inserted into the bracket front end 721, and at this time, the buckle position is snapped into the hole groove to realize the connection and fixation of the charging elastic piece 71 to the bracket front end 721.

[0053] Further, an infrared lens 28 for mounting the shrapnel bracket 72 is fixedly arranged on the tray body 2. An installation hole 281 for mounting the shrapnel bracket 72 is formed in the infrared lens 28. The installation hole 281 communicates with the accommodation cavity. The shrapnel bracket 72 is installed in the installation hole 281. The tail end 722 of the bracket is fixedly installed on the infrared lens 28 and located on the side of the installation hole 281 facing away from the accommodation cavity. The front end 721 of the bracket is movable in the installation hole 281, and the front end 721 of the bracket can extend from the installation hole 281 into the accommodation cavity.

[0054] The front end 721 of the bracket is floatingly connected to the tail end 722 of the bracket. Specifically, a second spring 73 is arranged between the front end 721 and the tail end 722 of the bracket. A guide post 74 is fixedly connected to the side of the front end 721 of the bracket facing the tail end 722 of the bracket. The second spring 73 is sleeved on the guide post 74. One end of the second spring 73 is fixedly connected to the front end 721 of the bracket, and the other end is fixedly connected to the tail end 722 of the bracket. A relief hole 7221 is formed in the tail end 722 of the bracket. The shape and size of the relief hole 7221 are adapted to the guide post 74. When the charging shrapnel 71 is squeezed, the second spring 73 is elastically compressed. At this time, the guide post 74 slides in the relief hole 7221. A bracket limit block is fixedly connected to the side of the front end 721 of the bracket close to the tail end 722 of the bracket. When the second spring 73 elastically releases, the bracket limit block abuts against the side of the infrared lens 28 facing away from the accommodation cavity. The bracket limit block restricts the movement of the front end 721 of the bracket to reduce the possibility of the front end 721 of the bracket being separated from the infrared lens 28. The front end 721 and the tail end 722 of the bracket are floatingly connected through the second spring 73. When the sweeper returns to charge and aligns, pressure is applied to the charging shrapnel 71, and the second spring 73 elastically contracts, so that the charging shrapnel 71 has a floating space in the axial direction of the guide post 74, ensuring the precise alignment between the charging shrapnel 71 and the charging contact of the sweeper; under the elastic action of the second spring 73, the charging shrapnel 71 can also be pressed against the charging contact of the sweeper to ensure full contact between the charging shrapnel 71 and the charging contact of the sweeper, effectively reducing the possibility of the sweeper charging failure due to poor contact. In other embodiments, the front end 721 and the tail end 722 of the bracket can be floatingly connected through other connection structures, such as elastomers made of rubber, polyurethane or other polymer materials, which are not uniquely defined herein.

[0055] In this embodiment, two guiding columns 74 are provided on the front end 721 of the bracket. Second springs 73 are sleeved on both of the two guiding columns 74. Correspondingly, relief holes 7221 corresponding to the two guiding columns 74 are formed in the rear end 722 of the bracket. Moreover, the front end 721 of the bracket has a certain curvature. Correspondingly, the charging elastic sheet 71 is also arranged with a certain curvature. The curvatures of the front end 721 of the bracket and the charging elastic sheet 71 match the curvature of the shape of the floor sweeper. When the floor sweeper comes into contact with the joint assembly 7 for charging, the curved shape can make the charging elastic sheet 71 fit better with the floor sweeper. Two second springs 73 are provided, and the two second springs 73 can be adjusted independently, thereby changing the inclination angle of the charging elastic sheet 71, further ensuring that the charging elastic sheet 71 is in contact with the charging contacts on the floor sweeper and improving the alignment error tolerance rate.

[0056] Referring to Figure 1 and Figure 4 , the climbing surface 21 is inclinedly arranged on the tray main body 2. Since the receiving cavity is usually arranged at a certain height from the ground, the climbing surface 21 is provided on the tray main body 2. The floor sweeper climbs along the climbing surface 21 to enter the receiving cavity. Usually, the floor sweeper extends into the receiving cavity in an inclined posture. The climbing surface 21 is connected to the receiving cavity, and a guiding groove 22 is formed on the climbing surface 21. The guiding groove 22 is used for the driving wheels of the floor sweeper to pass through and guides the floor sweeper to move along the guiding groove 22 to at least partially enter the receiving cavity.

[0057] Furthermore, there are two guiding grooves 22. The two guiding grooves 22 are symmetrically arranged on the climbing surface 21 and are in a "V" - shaped structure. The distance between the two guiding grooves 22 is adapted to the distance between the driving wheels of the floor sweeper. Moreover, the width of each guiding groove 22 gradually becomes narrower along the direction in which the floor sweeper crawls into the receiving cavity. The guiding grooves 22 are provided to limit the climbing direction of the floor sweeper to ensure that the floor sweeper climbs at the correct angle, which is beneficial to improving the alignment accuracy of the floor sweeper. The width of the guiding groove 22 gradually becomes narrower along the crawling direction of the floor sweeper, further increasing the guiding property of the floor sweeper entering the receiving cavity and enabling the floor sweeper to accurately drive into the predetermined position.

[0058] It should be noted that in the original text, the description of the "V" - shaped structure in the translation of item is based on the understanding of the text. If there is an error in the original text's description of the structure, please adjust it according to the actual situation.Further, a positioning groove 23 is also formed on the climbing surface 21, and the positioning groove 23 is formed on the side of the guiding groove 22 close to the accommodating cavity. The opening shape of the positioning groove 23 is adapted to the shape of the driving wheel of the floor sweeper. The positioning groove 23 further positions the floor sweeper for recharging alignment, so as to further ensure the accurate positioning of the floor sweeper and the accuracy of alignment. Moreover, through the arrangement of the positioning groove 23, the floor sweeper can be parked in the accommodating cavity in an inclined posture for charging operation with a simple structure. Two balance clamping points 25 are fixedly arranged on the climbing surface 21, and the two guiding grooves 22 are located between the two balance clamping points 25. The balance clamping points 25 on both sides support the floor sweeper. When the floor sweeper is parked in the positioning groove 23 for charging, it is in an inclined posture. The balance clamping points 25 are arranged to effectively support the floor sweeper, effectively reducing the possibility that the floor sweeper tilts or shakes during charging, resulting in inaccurate alignment and poor contact between the charging elastic sheet 71 and the charging contact of the floor sweeper, which affects the normal charging.

[0059] In one embodiment, anti-slip rib strips 24 are arranged at intervals in the advancing direction of the floor sweeper on the surfaces of the guiding groove 22 and the positioning groove 23. The free ends of the anti-slip rib strips 24 are in a wedge-shaped tip structure inclined towards the accommodating cavity. The arrangement of the anti-slip rib strips 24 can improve the grip ability of the driving wheel of the floor sweeper, making its climbing process smoother. It can be understood that in other embodiments, the friction between the floor sweeper and the guiding groove 22 and the positioning groove 23 can also be increased by other forms such as setting frosted surfaces, patterns or anti-slip layers on the surfaces of the guiding groove 22 and the positioning groove to ensure the smooth climbing of the driving wheel.

[0060] Furthermore, guiding surfaces 221 are also arranged on the climbing surface 21 on the sides where the two guiding grooves 22 are away from each other. The guiding surfaces 221 are inclined to the guiding grooves 22, and the inclination degree of the guiding surfaces 221 increases along the climbing of the guiding grooves 22. The guiding surfaces 221 are arranged to guide the driving wheels of the floor sweeper, so that the driving wheels of the floor sweeper can accurately enter the guiding grooves 22. Positioning inclined surfaces 231 are also formed on the climbing surface 21 on the sides where the positioning grooves 23 are away from each other. The positioning inclined surfaces 231 guide the driving wheels of the floor sweeper, so that the floor sweeper can accurately be stuck into the positioning grooves 23 when climbing along the guiding grooves 22.

[0061] In one embodiment, a limiting boss 26 matching the bottom bone position of the floor sweeper is fixedly connected to the bottom of the base body. When the driving wheel of the floor sweeper is stuck into the positioning groove 23, the limiting boss 26 abuts against the bottom bone position of the floor sweeper to mechanically position the floor sweeper, further ensuring the accuracy of the floor sweeper's recharging alignment. The top of the limiting boss 26 is in an arc chamfer structure. Setting the top in an arc chamfer structure is beneficial to reducing the possibility of the limiting boss 26 scratching the floor sweeper when the floor sweeper abuts against the limiting boss 26.

[0062] Currently, the base stations with and without automatic water supply and drainage on the market cannot be shared. The water tanks that only support one mode limit the application scope of the base stations. If you need to change from one mode to another, professional personnel need to come to your home for evaluation, installation, etc. The manufacturing cost and repair cost are relatively high, and the user experience is also poor.

[0063] Refer to Figures 4 to 14 According to, the sweeping robot base station of the present utility model further includes a base station main body 1, a tray main body 2 is arranged below the base station main body 1, a joint assembly 7 is electrically connected to the base station main body 1, and a water tank, a control unit and a water control module 4 are arranged on the base station main body 1. Its water tank is compatible with the functions of sweeping and the base station with and without automatic water supply and drainage. When the sweeping robot base station moves to a place where it is inconvenient to use the automatic water supply and drainage function, the base station can be manually filled or drained without affecting the normal use of sweeping and the base station. The water tank can be set as any one of the clean water tank 3 and the sewage tank 6 or both. Correspondingly, the sweeping robot base station is also provided with a clean water pumping pipeline 5 connected to the clean water tank 3 and a sewage pumping pipeline connected to the sewage tank.

[0064] Refer to Figures 4 to 6 Among them, the base station main body 1 is the main part of the base station device, used to accommodate and install various components of the sweeping robot base station; the tray main body 2 is the base part of the sweeping robot base station. When the sweeping robot returns to its position, it is on the tray main body 2. At this time, operations such as charging, cleaning the mopping cloth, and filling clean water can be carried out; the clean water tank 3 is connected to the clean water pumping pipeline 5. When the sweeping robot returns to its position and needs to clean the mopping cloth, the clean water tank 3 conveys clean water to the tray main body 2 through the clean water pumping pipeline 5 to clean the mopping cloth of the sweeping robot, and can also add water to the water tank of the sweeping robot; the sewage tank is connected to the sewage pumping pipeline, used to collect and store the sewage in the tray main body 2 and discharge the sewage into a specific pipeline. A drain port 27 is also opened on the tray main body 2, and the sewage for cleaning the mopping cloth can also be discharged from the drain port 27 to the outside of the base station main body 1. Conventional structures such as a dust collection and ash cleaning module and a control unit are also arranged on the base station main body 1. For details, reference can be made to the prior art, and the specific structure and working principle thereof will not be elaborated here.

[0065] Refer to Figure 7 According to, the water control module 4 is detachably arranged on the base station main body 1. The water control module 4 is connected to the water inlet or outlet of the water tank, that is, the water control module 4 can be installed in the clean water tank 3 to control the automatic filling of the clean water tank 3, and the water control module 4 can also be installed in the sewage tank 6 to control the automatic drainage of the sewage tank. When the water control module 4 is connected to the clean water tank 3, the water control module 4 is used to control whether the external pipeline fills the clean water tank 3. When the water control module 4 is installed on the base station main body 1, the water control module 4 is electrically connected to the base station main body 1.

[0066] Refer to Figure 7 and Figure 13, specifically, the water control module 4 includes a housing 41, a first solenoid valve 42 and a DC connector 43 fixedly arranged inside the housing 41. The input end of the first solenoid valve 42 is connected to an external water injection pipe, the output end of the first solenoid valve 42 is connected to the inside of the clean water tank 3, and the first solenoid valve 42 is electrically connected to the DC connector 43. A DC socket 11 is arranged on the base station main body 1, and the DC connector 43 is inserted into the DC socket 11 and conducts with it. When the water supply and drainage module is inserted onto the base station main body 1, it conducts with the control unit on the base station main body 1, and the control unit can control the opening or closing state of the first solenoid valve 42, thereby controlling whether to inject water into the clean water tank 3. When the base station is set at a location where automatic water supply is not available (such as no water injection pipe is reserved at the installation location of the base station), the water control module 4 can be disassembled. At this time, the clean water tank 3 can be taken out of the base station main body 1, and the clean water tank 3 can be filled with water by itself. And by integrating the DC plug and the first solenoid valve 42, when the water control module 4 is inserted onto the base station main body 1, it can conduct with the base station main body 1, and there is no need to connect the power supply to the first solenoid valve 42 separately, that is, only by supplying power to the base station main body 1, the first solenoid valve 42 can be powered on at the same time, effectively simplifying the overall structure.

[0067] Furthermore, a pipe joint 44 communicating the inside and outside of the housing 41 is arranged on the housing 41. The output end of the first solenoid valve 42 is connected to one end of the pipe joint 44 located inside the housing 41. The end of the pipe joint 44 communicating with the outside of the housing 41 protrudes out of the housing 41. An installation jack 14 is opened on the base station main body 1, and the installation jack 14 is adapted to the end of the pipe joint 44 protruding out of the housing 41. A water tank jack 322 (i.e., the water inlet of the clean water tank 3) is opened at the corresponding position of the clean water tank 3, and the water tank jack 322 communicates with the installation jack 14. The end of the pipe joint 44 away from the first solenoid valve 42 is inserted into the vertical jack and communicates with the inside of the water tank. When the control unit controls the first solenoid valve 42 to be in the open state, the water injection pipe communicates with the inside of the clean water tank 3, and the inside of the clean water tank 3 is filled with water through the water control module 4; when the control unit controls the first solenoid valve 42 to be in the closed state, the water injection pipe is not communicated with the inside of the clean water tank 3, and at this time, the water injection pipe cannot inject water into the clean water tank 3.

[0068] Further, the water control module 4 is detachably arranged on the base station main body 1. Specifically, on opposite sides of the housing 41, there are movably arranged clamping blocks 412 protruding outside the housing 41. The clamping blocks 412 are provided with a clamping portion 4122 and a pressing portion 4121. On the housing 41, there are provided a clamping hole 45 and a pressing hole 413. The clamping blocks 412 are movably arranged inside the housing 41, and the clamping portion 4122 and the pressing portion 4121 respectively protrude outside the housing 41 through the clamping hole 45 and the pressing hole 413. Inside the housing 41, there is also provided a first spring 414. On opposite sides inside the housing 41, there are fixedly arranged abutting plates. One end of the first spring 414 is connected to the abutting plate, and one end is connected to the clamping block 412. When pressing the pressing portion 4121 on the clamping blocks 412 on both sides of the housing 41, the first spring 414 elastically contracts, and the clamping portion 4122 of the clamping block 412 retracts into the housing 41. When the first spring 414 elastically releases, it drives the clamping block 412 to move, so that the clamping portion 4122 protrudes outside the housing 41. On the base station main body 1, there is provided a clamping hole 16, and the clamping portion 4122 of the clamping block 412 can be clamped with the clamping hole 16. When installing the water control module 4, first press the pressing portions 4121 on both sides to make the clamping portion 4122 retract, then align the pipe joint 44 with the installation jack 14, and make the clamping portion 4122 and the clamping hole 16 be on the same plane, then insert the water control module 4, and finally release the hand, so that the clamping portion 4122 is clamped with the clamping hole 16 to realize the installation and fixation of the water control module 4 on the base station main body 1.

[0069] In one embodiment, an installation groove 17 is provided on the base station main body 1. The installation groove 17 communicates with the installation jack 14. The clamping hole 16 is clamped on opposite side walls of the installation groove 17, and a part of the water control module 4 is installed in the installation groove 17.

[0070] In one embodiment, an insertion switch 15 is provided on the base station main body 1. Specifically, an insertion hole 18 is provided on the base station main body 1. The insertion switch 15 is arranged in the insertion hole 18 and is electrically connected to the control unit. An abutting column 411 is fixedly connected to the outside of the housing 41. The shape and size of the abutting column 411 are adapted to the insertion hole 18. When the pipe joint 44 is inserted into the water tank jack 322, the abutting column 411 is inserted into the insertion hole 18 to make the insertion switch 15 closed and conduct with the control unit. The insertion switch 15 is provided to protect the sweeping robot base station to prevent the accidental touch and activation of the automatic water supply and drainage mode of the control unit in the case of not applying the automatic water supply and drainage mode. When the insertion switch 15 is not closed and conducted, the control unit cannot activate the automatic water supply and drainage mode. Only when the insertion switch 15 is conducted and the DC plug is inserted into the DC socket 11, can the control unit activate the automatic water supply and drainage mode.

[0071] Refer to Figure 11 and Figure 12, a sensing member 323 for sensing the water level in the water tank 3 is arranged in the water tank 3. The sensing member 323 includes an upper water level sensor and a lower water level sensor. Among them, the lower water level sensor is fixedly arranged on one side of the water tank 3 close to the bottom, and the upper water level sensor is fixedly arranged on one side of the water tank 3 close to the opening. The sensing member 323 is signal-connected to the control unit in the base station main body 1. When the water level in the water tank 3 drops to the lower water level sensor (i.e., the preset low water level), the lower water level sensor sends a signal to the control unit, and the control unit starts the mechanical valve. At this time, the water injection pipe injects water into the water tank 3; when the water level rises to the upper water level sensor (i.e., the preset high water level), the upper water level sensor sends a signal to the control unit, and the control unit controls the mechanical valve to close. At this time, the water injection stops. The upper water level sensor and the lower water level sensor are arranged to monitor the water level in the water tank 3 in real time and can add water to the water tank 3 in a timely manner.

[0072] Furthermore, a ball valve 325 is also arranged in the water tank 3. The input end of the ball valve 325 is connected to the pipe joint 44. When the water level in the water tank 3 is relatively low, the ball valve 325 is in an open state. When water is injected into the water tank 3, the ball valve 325 is lifted under the action of water buoyancy. When the water level reaches the predetermined high water level, the ball valve 325 is in a closed state. At this time, even if the first solenoid valve 42 is in an open state, the water in the water injection pipe cannot enter the water tank 3. The coordinated use of the sensing member 323, the first solenoid valve 42 and the ball valve 325 provides double protection for the water injection process. Even if the upper water level sensor fails to timely sense that the water level reaches the preset high water level and sends a signal for the control unit to control the first solenoid valve 42 to close, the pipe joint 44 can be blocked by the mechanical structure of the ball valve 325, effectively reducing the possibility of water overflowing from the water tank 3 due to excessive water injection.

[0073] A first accommodation cavity 12 is formed on the base station main body 1. The base station main body 1 is provided with a positioning boss 121 located in the first accommodation cavity 12. The water tank 3 is provided with a positioning recess 321. The positioning boss 121 is adapted to the positioning recess 321. An outlet column 122 is arranged on the positioning boss 121. The water tank 3 is provided with an outlet hole 326. The outlet hole 326 is arranged on the positioning recess 321. When the water tank 3 is installed in the first accommodation cavity 12, the outlet column 122 is inserted into the outlet hole 326. One end of the outlet column 122 facing away from the outlet hole 326 is connected to the water pumping pipeline 5. A water outlet pipe (not shown in the figure) connected to the bottom of the water tank 3 is arranged at the outlet hole 326 of the water tank 3. The water in the water tank 3 is pumped into the water pumping pipeline 5 through the water outlet pipe. In order to ensure the sealing performance between the outlet column 122 and the outlet hole 326, a tower-shaped sealing ring is sleeved on the outlet column 122. When the water tank 3 is installed in the first accommodation cavity 12, the tower-shaped sealing ring abuts between the outlet hole 326 and the positioning boss 121, realizing the connection seal between the water tank 3 and the base station main body 1.

[0074] In one embodiment, referring to Figure 7 , the clean water pumping pipeline 5 (only the main components are shown in the figure) includes a clean water pump, a clean water pipe, and a reversing valve. The clean water pump is fixedly arranged on the base station main body 1 and is electrically connected to the control unit. The clean water pump and several clean water pipes are connected to form a first pumping branch and a second pumping branch. The first pumping branch is connected to the water path of the nozzle of the tray main body 2 to clean the mop of the floor sweeper; when the floor sweeper returns to its position, the second pumping branch can be docked with the water tank inlet joint of the floor sweeper to fill the water tank of the floor sweeper. The reversing valve is connected to the confluence of the first pumping branch and the second pumping branch to realize the switching between the two branches.

[0075] In one embodiment, referring to Figure 12 , the clean water tank 3 includes a clean water tank body 32 and a clean water tank upper cover 31. The clean water tank upper cover 31 is rotatably connected to the clean water tank body 32. A clean water tank seal 33 is connected between the clean water tank body 32 and the clean water tank upper cover 31. The clean water tank seal 33 is in interference fit with the clean water tank upper cover 31. When the clean water tank upper cover 31 completely covers the clean water tank body 32, the clean water tank seal 33 is in interference fit with the upper end face of the clean water tank body 32 to realize the sealing of the clean water tank 3. The clean water tank upper cover 31 and the clean water tank body 32 can be connected and fixed through a snap structure or the like, which is not uniquely limited here. To facilitate the handling of the clean water tank 3, a clean water tank handle 34 is fixedly arranged on the upper end face of the clean water tank upper cover 31. The provision of the clean water tank handle 34 facilitates taking out the clean water tank 3 from the base station main body 1.

[0076] In one embodiment, a filter 324 is arranged at the bottom of the clean water tank 3, and slow-release particles are arranged in the filter 324 to sterilize and disinfect the inside of the clean water tank 3.

[0077] Referring to Figure 7 , Figure 11 and Figure 14, in one embodiment, it further includes a sewage tank 6 for collecting and storing sewage in the tray body 2. The base station body 1 is provided with a sewage pumping pipeline connected to the sewage tank 6 (only the main components of the sewage pumping pipeline are shown in the figure). Specifically, a second accommodation cavity 13 is formed on the base station body 1. The base station body 1 is provided with a sewage discharge boss 131 and an air inlet / outlet boss 134 in the second accommodation cavity. The sewage tank 6 is arranged in conformity with the second accommodation cavity 13 and substantially fills the second accommodation cavity 13. A sewage suction column 133 and a sewage discharge column 132 are arranged on the sewage discharge boss 131. The corresponding positions on the sewage tank 6 are provided with a sewage suction hole 622 and a sewage discharge hole 623. The sewage suction hole 622 and the sewage discharge hole 623 are respectively in corresponding communication with the sewage suction column 133 and the sewage discharge column 132. An air inlet / outlet column 135 is arranged on the air inlet / outlet boss 134. An air inlet / outlet hole 621 is arranged at the corresponding position of the sewage tank 6, and the air inlet / outlet hole 621 is in conduction with the air inlet / outlet column 135. The sewage pumping pipeline includes an air extraction branch 8, a sewage discharge branch 9 and a sewage suction branch 10. The air extraction branch 8 is connected to the air inlet / outlet column 135, the sewage discharge branch 9 is connected to the sewage discharge column 132, and the sewage suction branch 10 is connected to the sewage suction column 133. The air extraction branch 8 forms a positive pressure or negative pressure environment in the sewage tank to realize the working state of discharging or sucking sewage from the sewage tank 6. The water control module 4 can also be installed on the sewage tank 6 (such as connected to the water outlet of the sewage tank 6) to control the sewage tank 6 to drain automatically. The setting method refers to the connection structures of the above-mentioned water tank 3 and the water control module 4 and will not be elaborated here.

[0078] In one embodiment, the air extraction branch 8 is composed of an air extraction pump 81, two micro solenoid valves 82 (for air) and several air pipes. An air pump bracket for fixing the air extraction pump 81 and the micro solenoid valves 82 is arranged on the base station body 1. The air extraction pump 81 and the micro solenoid valves 82 are electrically connected to the control unit. The air inlet and outlet of the air extraction pump 81 are respectively and hermetically connected to different interfaces of the two micro solenoid valves 82 through air pipes. Each micro solenoid valve 82 is provided with three air ports. The two micro solenoid valves 82 are then connected to the air inlet / outlet hole 621 of the sewage tank through air pipes and a three-way pipe. Different air ports are connected to switch different paths when the micro solenoid valves 82 are energized and de-energized, so as to realize a positive pressure environment or a negative pressure environment in the sewage tank 6.

[0079] Refer to Figure 9 and Figure 11, the sewage suction branch 10 and the sewage discharge branch 9 are respectively composed of a one-way valve and several water pipes. The sewage suction one-way valve of the sewage suction branch 10 is arranged along the sewage suction path direction, and the sewage suction water pipes are connected to both ends of the sewage suction one-way valve, communicating the sewage suction column 133 and the tray main body 2. By setting the sewage suction one-way valve, the sewage on the tray main body 2 can only enter the sewage tank 6 from the tray main body 2 through the sewage suction one-way valve, and will not flow back from the sewage tank 6 to the tray main body 2, effectively ensuring the sealing of the overall structure during sewage suction. Similarly, the sewage discharge water pipes of the sewage discharge branch 9 are arranged along the sewage discharge path direction, and the sewage can only be discharged from the sewage discharge water pipes outside the sewage tank 6, and will not flow back from the sewage discharge water pipes to the sewage tank 6.

[0080] In one embodiment, referring to Figure 11 and Figure 14 The sewage tank 6 includes a sewage tank body 62 and a sewage tank upper cover 61. The sewage tank upper cover 61 is rotatably connected to the sewage tank body 62, and a sewage tank seal 63 buoy 624 is connected between the sewage tank body 62 and the sewage tank upper cover 61; the sewage tank seal 63 buoy 624; is in interference fit with the sewage tank upper cover 61. When the sewage tank upper cover 61 is completely covered on the sewage tank body 62, the sewage tank seal 63 buoy 624; is in interference fit with the upper end face of the sewage tank body 62 to achieve the sewage tank seal. The sewage tank upper cover 61 and the sewage tank body 62 can be connected and fixed through a snap structure or the like, which is not uniquely limited here. In order to facilitate the handling of the sewage tank 6, a sewage tank handle 64 is fixedly arranged on the upper end face of the sewage tank upper cover 61. By setting the sewage tank handle 64, it is convenient to take out the sewage tank 6 from the base station main body 1.

[0081] A buoy 624 is also arranged in the sewage tank 6. The buoy 624 is signal-connected to the control unit. When the water level in the sewage tank 6 reaches a predetermined maximum value, the buoy 624 sends a signal to the control unit. When receiving the signal, the control unit controls the sewage tank 6 to automatically discharge sewage (when having the function of automatic water supply and drainage), or issues a sewage full signal (when not having the function of automatic water supply and drainage) to remind the user to pour out the sewage.

[0082] The working principle of the floor sweeping robot base station of the present utility model is as follows:

[0083] At least a fresh water tank 3 is detachably provided on the base station main body 1. The base station main body 1 can also be equipped with both a fresh water tank 3 and a sewage tank 6. When only the fresh water tank 3 is provided on the base station main body 1 without the sewage tank 6, the drain port 27 on the tray main body 2 can be externally connected with a pipeline to directly lead the sewage generated by the sweeping robot base station to a floor drain or a place where sewage can be discharged, and directly discharged. When the base station main body 1 has both a fresh water tank 3 and a sewage tank 6, the sewage pumping pipeline is connected to the drain port 27 of the tray main body 2 to lead the sewage generated by the sweeping robot base station into the sewage tank 6 for collection and then discharged. When the base station main body 1 is in the non-automatic water supply and drainage mode (that is, the water control module 4 is not inserted into the base station main body 1), at this time, the fresh water tank 3 cannot be automatically filled with water, and the sewage tank 6 cannot be automatically drained of sewage. At this time, it is necessary to manually disassemble the fresh water tank 3 and the sewage tank 6 respectively to add fresh water and pour out sewage. When the base station main body 1 is in the automatic water supply and drainage mode (that is, the water control module 4 is inserted into the base station main body 1), at this time, the base station main body 1 can automatically perform the water supply and sewage discharge operations. The sweeping robot base station provided by the present utility model is compatible with both the water supply and drainage function and the non-water supply and drainage function, effectively improving the applicable range of the sweeping robot base station. Users can choose whether to have the automatic water supply and drainage function by themselves, and there is no need to replace the base station main body 1, the fresh water tank 3 and the sewage tank 6, effectively improving the user experience.

[0084] The present utility model also provides:

[0085] A cleaning system, including a sweeping robot base station with the above-mentioned structure.
