A base station according to an embodiment of the present utility model, which includes a base station body 100, a water blocking valve 200, and a water tank 300, is exemplarily described with reference to fig. 1 to 6.

The base station body 100 may be connected to an external water supply unit to receive water supply of the external water supply unit. The external water supply unit may be a tap, a tap water pipe, or other means or structure capable of supplying clean water, and the water tank 300 is detachably connected to the base station body 100, and the base station body 100 serves to convey clean water from the external water supply unit to the water tank 300, thereby replenishing the water tank on a cleaning device (such as a mopping robot, a sweeping robot) entering the base station body 100 through the water tank 300.

Specifically, in the embodiment of the present utility model, the base station body 100 includes a first housing 110, a second housing 120, and a water inlet control unit 130. The first housing 110 includes a first receiving space 113, and a water outlet port 111 and a first through hole communicating with the first receiving space 113. The second housing 120 is detachably connected to the first housing 110, and includes a second receiving space 122, and a socket part 121 and a second through hole communicating with the second receiving space 122. The first end and the second end of the plugging portion 121 are both cylindrical, the first end of the plugging portion 121 extends from the second housing 120 into the second accommodating space 122, and the second end of the plugging portion 121 extends from the second housing 120. When the second housing 120 is connected to the first housing 110, the second end of the plugging portion 121 protrudes into the first receiving space 113 through the first through hole. The water inlet control unit 130 is connected with the water outlet 111 at one end and the other end, and the other end is used for being connected with an external water supply unit, the water inlet control unit 130 is used for controlling the connection and disconnection of a liquid path between the external water supply unit and the water outlet 111, when the liquid path between the external water supply unit and the water outlet 111 is connected, clean water from the external water supply unit can be output to the outside of the base station main body 100 through the water outlet 111, and when the liquid path between the external water supply unit and the water outlet 111 is disconnected, clean water from the external water supply unit cannot be output to the outside of the base station main body 100 through the water outlet 111. In the embodiment of the present utility model, the water supply of the external water supply unit has a certain water pressure, and the water inlet control unit 130 includes a controller, a solenoid valve 131, a first connection pipe 132, and a second connection pipe 133. The first connection pipe 132 is a plastic hose partially located in the second receiving space 122, a first end of the first connection pipe 132 is connected with a first end of the socket 121, and a second end of the first connection pipe 132 may pass through the second through hole to be connected with an external water supply unit. The second connection pipe 133 is a plastic hose, and is disposed in the first accommodating space 113, a first end of the second connection pipe 133 is connected to the water outlet 111, and a second end of the second connection pipe 133 is connected to the second end of the plugging portion 121. Accordingly, the fresh water from the external water supply unit may be sequentially transferred to the water outlet 111 through the first connection pipe 132, the socket part 121, and the second connection pipe 133, and outputted to the outside of the base station main body 100 through the water outlet 111. The electromagnetic valve 131 is disposed on the first connection pipe 132, which can be switched between an open state and a closed state, when the electromagnetic valve 131 is in the open state, the first connection pipe 132 is smooth, that is, the liquid path between the external water supply unit and the water outlet port 111 is communicated, and the clean water from the external water supply unit can be sequentially transferred to the water outlet port 111 through the first connection pipe 132, the plugging portion 121 and the second connection pipe 133; when the solenoid valve 131 is in the closed state, the first connection pipe 132 is closed, that is, the liquid path between the external water supply unit and the water outlet port 111 is opened, and the clean water from the external water supply unit cannot pass through the first connection pipe 132 and cannot be outputted to the outside of the base station main body 100 through the water outlet port 111. The controller may be a single chip microcomputer or other suitable control device connected to the solenoid valve 131 for controlling the solenoid valve 131 to switch between an open state and a closed state to control the connection and disconnection of the liquid path between the external water supply unit and the water outlet port 111.

In other embodiments, when the water supply of the external water supply unit has a certain water pressure, the solenoid valve 131 may be replaced with a clamping mechanism located outside the first connection pipe 132 for clamping or unclamping the first connection pipe 132, and when the clamping mechanism clamps the first connection pipe 132, the first connection pipe 132 is closed, and the fresh water from the external water supply unit cannot pass through the first connection pipe 132; when the clamping mechanism releases the first connection pipe 132, the first connection pipe 132 is unobstructed, and clear water from the external water supply unit may pass through the first connection pipe 132. A controller is coupled to the clamping mechanism for controlling the clamping or unclamping of the first connecting tube 132. In other embodiments, when the water supply of the external water supply unit does not have the water pressure or the water pressure is low, the electromagnetic valve 131 may be replaced with a water pump provided on the first connection pipe 132 for pumping the clean water from the external water supply unit to the water outlet 111 to be outputted to the outside of the base station main body 100 when in operation, and when the operation is stopped, the clean water from the external water supply unit cannot flow to the water outlet 111 through the first connection pipe 132, the socket 121 and the second connection pipe 133 due to the lack of the water pressure or the low water pressure.

In the embodiment of the present utility model, the controller, the solenoid valve 131 and the first connection pipe 132 are disposed in the second housing 120 detachably connected to the first housing 110, so that the controller, the solenoid valve 131 and the first connection pipe can be integrally assembled as one module of the base station, thereby realizing the modular design of the base station and being convenient to detach for maintenance or replacement. In other embodiments, the base station may have only the first housing 110, the water inlet control unit 130 is disposed in the first housing 110, and the water inlet control unit 130 may include a connection pipe having a first end connected to the water outlet 111 and a second end connected to the external water supply unit through the first through hole, a solenoid valve 131 (or a clamping mechanism, or a water pump), and a controller.

In the embodiment of the present utility model, the water outlet 111 is tubular, and has a first end with a water inlet 1110, a second end with a water outlet 1111, and a first flow channel 1112 between the water inlet 1110 and the water outlet 1111. The first end of the second connecting pipe 133 is sleeved on the water outlet 111, and the clean water from the second connecting pipe 133 is discharged out of the base station main body 100 through the water inlet 1110, the first flow channel 1112 and the water outlet 1111 in sequence. In the embodiment of the present utility model, the circumferential edge of the second end of the water outlet 111 is further provided with a tubular extension 1113 extending away from the water outlet 1111, and the cross-sectional area of the extension 1113 along the extension direction of the first flow channel 1112 is larger than the area of the water inlet 1110, which is used to increase the contact area between the second connecting pipe 133 sleeved on the water outlet 111 and the water outlet 111, and improve the combination firmness of the two.

The water blocking valve 200 is provided at the water outlet port 111 and is configured to be switchable between a first position, in which the water outlet port 111 is opened, and a second position, in which the water outlet port 111 is closed. Specifically, the water trap 200 includes a first end 210, a second end 220, and a connecting section 230 connecting the first end 210 and the second end 220. The first end 210 is located outside the water inlet 1110, the second end 220 is located outside the water outlet 1111, the connection section 230 is disposed through the first flow channel 1112, and the cross-sectional area of the connection section 230 along the extending direction of the first flow channel 1112 is smaller than the cross-sectional area of the first flow channel 1112, and the length of the connection section 230 along the extending direction of the first flow channel 1112 is longer than the length of the first flow channel 1112, so that although the connection section 230 is disposed in the first flow channel 1112, there is sufficient flow space in the first flow channel 1112. The first end 210 is tapered with a sectional area gradually increasing in a direction from the first end 210 to the second end 220, and an area of an end surface of the first end 210 toward the water inlet 1110 is larger than an area of the water inlet 1110. The second end 220 has a disc shape, and a hollow portion 221 is disposed on the second end, so that clean water flowing out of the water outlet 1111 can flow from the second end 220 to a side of the second end 220 away from the water outlet 1111 through the hollow portion 221. The water blocking valve 200 may be moved in the extending direction of the first flow channel 1112 to switch between a first position and a second position, when the water blocking valve 200 is in the first position, the first end 210 of the water blocking valve 200 is separated from the water inlet 1110, the water inlet 1110 is opened, and the clean water from the second connection pipe 133 may enter the first flow channel 1112 from the gap between the first end 210 and the water inlet 1110, and further flow out from the water outlet 1111. When the water blocking valve 200 is at the second position, the side of the first end 210 facing the water inlet 1110 is attached to the water inlet 1110 to cover and close the water inlet 1110, and the clean water from the second connecting pipe 133 cannot enter the first flowing channel 1112, and cannot flow out of the water outlet 1111.

In the embodiment of the present utility model, the base station further includes a spring 400, where the spring 400 is disposed between the second end 220 of the water blocking valve 200 and the base station main body 100 outside the water outlet 1111, and is used to push the water blocking valve 200 to move in a direction from the water inlet 1110 to the water outlet 1111 by self-elasticity when the second end 220 is not acted on by external force, so that the water blocking valve 200 is kept at the second position, and the water outlet 1111 is closed. When the second end 220 is subjected to an external force from the water outlet 1111 toward the water inlet 1110, the spring 400 is compressed, so that the water blocking valve 200 can move in a direction from the water outlet 1111 toward the water inlet 1110 to move from the second position to the first position, opening the water outlet 1111. In other embodiments, the spring 400 may be replaced with a silicone washer, a metal spring plate, or other suitable resilient member.

The water tank 300 is detachably connected to the base station body 100, and in particular, the water tank 300 may be detachably connected to the base station body 100 by a plug-in connection, a snap-in connection, or other connection means known to those skilled in the art. The water tank 300 is provided with a tubular water inlet port 310, a second flow channel 312 is arranged in the water inlet port 310, a third accommodating space 320 for accommodating clean water is arranged in the water tank 300, and the third accommodating space 320 is communicated with the outside of the water tank 300 through the second flow channel 312. The base station body 100 further includes a socket 114 communicating with the water outlet 1111, and the water outlet 1111 and the second end 220 of the water blocking valve 200 are positioned at the bottom of the socket 114. Referring to fig. 4, when the water tank 300 is connected to the base station main body 100, the water inlet port 310 is inserted into the insertion slot 114, and presses the second end 220 to push the water blocking valve 200 to move to the first position, the water inlet 1110 is opened, and the hollowed-out portion 221 is communicated with the second circulation channel 312 in the water inlet port 310, so that water from the water outlet port 111 enters the second circulation channel 312 in the water inlet port 310 through the hollowed-out portion. At this time, the spring 400 is compressed, and the fresh water from the second connection pipe 133 may sequentially pass through the water inlet 1110, the first flow channel 1112, the water outlet 1111, the hollowed-out portion 221, and the second flow channel 312 to enter the receiving space in the water tank 300, that is, the base station main body 100 may supply water to the water tank 300 through the water outlet 111 and the water inlet 310. Referring to fig. 6, when the water tank 300 is separated from the base station body 100, the water inlet port 310 is separated from the second end 220, and the second end 220 is not pressed, the spring 400 pushes the water blocking valve 200 to move in a direction from the water inlet 1110 to the water outlet 1111 by self-elasticity, so that the water blocking valve 200 moves to the second position and is maintained at the second position, closing the water inlet 1110, and at this time, the clean water from the second connection pipe 133 cannot enter the first flow channel 1112 through the water inlet 1110, and cannot leave the base station body 100. Thus, with the base station according to the embodiment of the present utility model, if the user accidentally lifts the water tank 300 to separate the water tank 300 from the base station body 100 while the base station body 100 supplies water to the water tank 300 through the water outlet port 111 and the water inlet port 310, the spring 400 may push the water blocking valve 200 to move to the second position to block the water inlet 1110 when the water inlet port 310 is separated from the second end 220, cutting off the water flow, and effectively preventing the water supply of the water inlet control unit 130 from leaking from the water outlet port 111 of the base station body 100.

In the embodiment of the present utility model, when the water tank 300 is connected to the base station main body 100, the water inlet port 310 and other parts of the water tank 300 may close the notch of the insertion groove 114 (i.e., the upper opening of the insertion groove 114), so that the clean water flowing out from the water outlet port 111 will not leak out through the insertion groove 114. In other embodiments, the water inlet port 310 or other portion of the water tank 300 may not close the top opening of the mating groove 114 when the spring 400 is replaced with an elastic member (e.g., a silicone gasket or other suitable elastic member) that is capable of forming a seal between the second end 220 and the water outlet 1111.

In other embodiments, if the water pressure in the second connection pipe 133 is sufficiently large, the spring 400 or other elastic member may not be provided between the second end 220 of the water blocking valve 200 and the base station body 100 outside the water outlet 1111. When the water tank 300 leaves the base station main body 100, the water inlet 310 is separated from the second end 220, and the second end 220 is not pressed any more, and the water flow in the second connecting pipe 133 pushes the first end 210 to move toward the water inlet 1110, so that the water inlet 1110 is closed.

In an embodiment of the present utility model, a one-way valve is disposed in the second flow channel 312 in the water inlet port 310 and is configured to allow fluid to enter the third receiving space 320 in the water tank 300 through the second flow channel 312, and to restrict fluid in the water tank 300 from flowing out of the water tank 300 through the second flow channel 312. The one-way valve may be a duckbill valve or other suitable one-way valve. The one-way valve is provided so that water in the water tank 300 does not leak out through the water inlet port 310 when the water tank 300 is separated from the base station main body 100.

In the embodiment of the present utility model, the base station body 100 further includes a bit detection unit 140. The bit detection unit 140 is used to detect whether the water tank 300 is separated from the base station main body 100. Specifically, the in-situ detection unit 140 may include a hall sensor, an infrared sensor, or an ultrasonic sensor. When the in-place detecting unit 140 includes a hall sensor, the water tank 300 is provided with a magnetic member corresponding to the hall sensor. In some embodiments, to include a switch circuit and a trigger (e.g., switch, contact, etc.) connected to the switch circuit in the presence detection unit 140, when the water tank 300 is connected to the base station main body 100, the water tank 300 triggers the trigger to turn on the switch circuit; when the water tank 300 is separated from the base station body 100, the switching circuit is turned off. In some embodiments, the in-situ detection unit 140 may also be other suitable contact sensors and proximity sensors.

The water inlet control unit 130 is connected to the in-place detecting unit 140 and the water inlet port 111, for supplying water to the water tank 300 through the water inlet port 310 and the water outlet port 111 when the water tank 300 is connected to the base station body 100, and for stopping supplying water to the water tank 300 through the water inlet port 310 and the water outlet port 111 when the water tank 300 is separated from the base station body 100. Specifically, in the embodiment of the present utility model, the controller is connected to the in-situ detecting unit 140 for acquiring whether the water tank 300 is separated from the base station main body 100. When the controller obtains that the water tank 300 does not leave the base station main body 100 (i.e., the water tank is connected to the base station main body), the controller can control the electromagnetic valve 131 to be opened, so that the liquid path between the external water supply unit and the water outlet port 111 is communicated, and clean water from the external water supply unit can enter the third accommodating space 320 in the water tank 300 through the water outlet port 111 and the water inlet port 310, so that water supply to the water tank 300 is realized. When the controller obtains that the water tank 300 does not leave the base station main body 100, the controller may control the solenoid valve 131 to close so as to disconnect the liquid path between the external water supply unit and the water outlet 111, for example, when the water tank 300 is filled with water. When the controller obtains that the water tank 300 is separated from the base station main body 100 (i.e., when the water tank 300 is separated from the base station main body 100), the controller controls the electromagnetic valve 131 to be closed, so that the liquid path between the external water supply unit and the water outlet port 111 is disconnected, and clean water from the external water supply unit cannot pass through the first connecting pipe 132 and cannot be output to the outside of the base station main body 100 through the water outlet port 111. Note that, if the solenoid valve 131 is already in the closed state at this time, the solenoid valve 131 is controlled to remain in the closed state. Thus, if the user accidentally lifts the water tank 300 to separate the water tank 300 from the base station body 100 while the base station body 100 supplies water to the water tank 300 through the water outlet port 111 and the water inlet port 310, the controller may control the liquid path between the external water supply unit and the water outlet port 111 to be disconnected when the in-situ detection unit 140 detects that the water tank 300 is separated from the base station body 100, thereby preventing the user from accidentally lifting the water tank 300 to cause water leakage from the water outlet port 111 of the base station body 100. The embodiment of the utility model realizes double protection of water leakage of the base station main body 100 through the cooperation of the water inlet control unit 130 and the in-situ detection unit 140 and the arrangement of the water retaining valve 200. In addition, the water inlet control unit controls the liquid path between the external water supply unit and the water outlet port 111 to be disconnected when the water tank 300 is separated from the base station body 100, so that the clear water from the external water supply unit can be prevented from leaking from the water outlet port 111 when the water blocking valve 111 fails.

In an embodiment of the present utility model, the water tank 300 further includes a liquid level detection unit for detecting a liquid level in the water tank 300. Specifically, the liquid level detecting unit includes a liquid-air detecting sensor 330 disposed at the bottom of the third accommodating space 320 and a liquid-full detecting sensor 340 disposed at the upper portion of the third accommodating space 320, where the liquid-air detecting sensor 330 is configured to be triggered when the liquid level reaches or falls below a first height, and the liquid-full detecting sensor 340 is configured to be triggered when the liquid level reaches or exceeds a second height, and the second height is higher than the first height. In some embodiments, the liquid level detection unit may further include a float disposed in the third receiving space 320. The float may move synchronously with the change in the level of the liquid in the tank 300, the float triggering the liquid empty detection sensor 330 when the liquid level reaches or falls below a first level, and the float triggering the liquid full detection sensor 340 when the liquid level reaches or falls above a second level. The liquid-air detection sensor 330 and the liquid-full detection sensor 340 may be an infrared sensor, an ultrasonic sensor, or a hall sensor. In some embodiments, the liquid level detection unit may be a capacitive sensor provided at different heights outside the water tank 300, which may detect the liquid level according to different capacitance changes in the water-present state and the water-free state. In some embodiments, the liquid level detecting unit may be a ranging sensor provided at the top of the third receiving space 320, for transmitting a detection signal to the bottom of the third receiving space 320, receiving the reflected detection signal, and then calculating the current liquid level of the water tank 300 according to the signal flight time. The detection signal may be, for example, an ultrasonic signal or other suitable detection signal.

The water inlet control unit 130 is connected with the liquid level detection unit, and is used for controlling the communication of the liquid path between the external water supply unit and the water outlet interface 111 when the water tank 300 is connected to the base station main body 100 and the liquid level in the water tank 300 reaches or is lower than the first height; when the water tank 300 is connected to the base station body 100 and the liquid level in the water tank 300 is higher than the second height, the disconnection of the liquid path between the external water supply unit and the water outlet port 111 is controlled. Specifically, when the water tank 300 is connected to the base station main body 100, the controller in the water inlet control unit 130 is electrically connected to the liquid level detection unit, and the detection result of the liquid level detection unit is obtained. When the liquid level detection unit detects that the liquid level in the water tank 300 reaches or falls below the first height, the controller controls the solenoid valve 131 to open, and fresh water from the external water supply unit may enter the third receiving space 320 in the water tank 300 through the water outlet port 111 and the water inlet port 310, that is, the water inlet control unit 130 supplies water to the water tank 200 through the water outlet port 111 and the water inlet port 210; when the liquid level detection unit detects that the liquid level in the water tank 300 reaches or exceeds the second height, the controller controls the solenoid valve 131 to be closed, and the fresh water from the external water supply unit cannot pass through the first connection pipe 132 and cannot be output to the water tank 300 through the water outlet port 111, that is, the water inlet control unit 130 stops supplying water to the water tank 200 through the water outlet port 111 and the water inlet port 210. Thus, the embodiment of the present utility model can realize automatic water replenishment of the water tank 300 when the water tank 300 is connected to the base station main body 100.

In this embodiment, the base station main body 100 further includes an accommodating space for accommodating a cleaning device (e.g., a floor mopping robot, a floor sweeping robot, etc.), and a cleaning device water replenishing assembly for supplying clean water in the water tank 300 into a clean water tank on the cleaning device after the cleaning device enters the accommodating space, so as to replenish the clean water tank of the cleaning device with water by the base station. The specific construction of the refill assembly of the cleaning device is known to those skilled in the art and will not be described in detail herein.

The embodiment of the utility model also provides a cleaning system which comprises the base station and the cleaning equipment. The cleaning device may be a mopping robot, a sweeping robot or the like, the cleaning device having a fresh water tank in which fresh water may be used to wet a roller, mop or the like on the cleaning device. The base station is used for supplying water to a clean water tank of the cleaning apparatus through the water tank 300 when the cleaning apparatus travels to a preset position in the base station, so as to realize water replenishment of the clean water tank.
