All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The present inventors have long studied and found that cleaning systems often require a cleaning fluid, such as water, for cleaning activities or self-cleaning. The base station of the cleaning system is often provided with a water tank for supplying water for cleaning or self-cleaning activities of the cleaning system. In the prior art, a user is required to add water to the water tank, which certainly consumes time and effort of the user. Even if the water tank is in communication with the mains, it is necessary for the user to open and close the mains valve to control the amount of water in the water tank. In order to solve this technical problem, the present application provides the following examples.

As shown in fig. 1, the cleaning system 3 comprises a cleaning device 2 and a base station 1, which can clean a scene to be cleaned. The cleaning device 2 may have the function of one or more of sweeping, washing, mopping, and cleaning. For example, the cleaning device 2 may be a floor sweeping robot, a floor mopping robot, a washing and mopping robot, a sweeping and mopping robot, a floor washing machine, or the like.

The base station 1 described in the base station embodiments of the present application is used in connection with a cleaning device 2, and may be used to clean the cleaning device 2, for example, to clean a side sweeping and/or mopping mechanism on the cleaning device 2. For example, the base station 1 may further clean the cleaning device 2 after sucking the refuse objects stored in the cleaning device 2, so that the cleaning device 2 may be dispensed with manually cleaning. Further, the base station 1 may be connected to a tap water pipe in a scene to be cleaned to automatically obtain clean water, or may be connected to a sewer pipe in a scene to be cleaned to automatically drain sewage.

Alternatively, the base station 1 can charge the cleaning device 2. For example, the cleaning device 2 can be automatically moved to the base station 1, and can be charged after being connected to each other. Alternatively, the base station 1 may also suck up the objects of waste stored by the cleaning device 2, which may be referred to as a dust collection base station. In this way, the cleaning device 2 can be cleaned of waste without the need for manual work. The functions of the base station 1 may be numerous, the above list being merely an example. The following is an exemplary structure of the base station 1 described in the base station embodiment of the present application.

As shown in fig. 2 and 3, the base station 1 includes a base station body 20 and a float assembly 10. The base station body 20 includes a water tank 21 and a liquid inlet pipe 22 communicating with the inside of the water tank 21. The float assembly 10 is disposed inside the water tank 21, and the float assembly 10 includes a fixing member 200, the fixing member 200 is connected to the liquid inlet pipe 22, and the liquid inlet channel 201 communicates with the liquid inlet pipe 22 to receive the liquid flowing out of the liquid inlet pipe 22.

One end of the liquid inlet pipe 22 far away from the water tank 21 can be connected with a tap water pipe in a normally open state in a scene to be cleaned so as to automatically obtain clean water. The water tank 21 may contain a cleaning liquid for cleaning the cleaning device 2. The cleaning liquid is, for example, clear water, or a mixed liquid between water and a cleaning agent, or a mixed liquid between water and a disinfectant, or a mixed liquid between water, a cleaning agent and a disinfectant. Of course, the cleaning liquid may be another liquid.

The float assembly 10 is disposed within the water tank 21 such that there is a threshold level of liquid within the water tank 21, and when the liquid level within the water tank 21 is below the threshold level, the float assembly 10 allows liquid flowing out of the liquid inlet channel 201 to flow into the water tank 21. When the liquid level in the tank 21 reaches a threshold, the float assembly 10 is buoyant to prevent liquid flowing from the liquid inlet channel 201 from entering the tank 21.

Alternatively, the base station 1 may comprise a base 30. The base station body 20 is connected to the base 30. For example, the base station body 20 may be disposed at one side of the base 30, or the base station body 20 may be disposed above the base 30. The base 30 may be used to carry the cleaning device 2. For example, the cleaning device 2 may walk to the base 30 and rest on the base 30. The base station body 20 can suck up the objects of the waste in the cleaning device 2 carried on the base 30.

Alternatively, the base station 1 may have a dust box 23, a sewage box 24, a suction mechanism 25, a water pumping mechanism 26, a liquid supply mechanism 27, and a gas supply mechanism 28. Specifically, the base station body 20 has a dust box 23, a sewage box 24, a suction mechanism 25, a water pump mechanism 26, a liquid supply mechanism 27, and a gas supply mechanism 28. Further, the base station body 20 may further have a first housing 29. The dust box 23, the water tank 21, the sewage tank 24, and the air supply mechanism 28 may be provided in the first housing 29 at a distance from each other. The suction mechanism 25 is used to suck the objects of dust in the cleaning apparatus 2 into the dust box 23. The dust bin 23 serves to retain the dust objects sucked from the cleaning apparatus 2. The sewage tank 24 is used for containing sewage or waste liquid generated after washing the cleaning apparatus 2. The water pump 26 pumps the sewage generated after washing the cleaning apparatus 2 into the sewage tank 24. The water pump 26 may also be connected to a sewer line in the scene to be cleaned to automatically pump sewage to the sewer line. The liquid supply mechanism 27 is used to convey or pump the cleaning liquid of the water tank 21 to the cleaning apparatus 2. The air supply mechanism 28 is used for supplying a drying air, and thus can dry the corresponding area after the cleaning device 2 is cleaned.

Alternatively, the base station 1 may comprise a cleaning assembly 31, which may be provided for example on the base 30. The cleaning assembly 31 may be used to clean the mopping mechanism of the cleaning device 2. The cleaning assembly 31 may communicate with the water tank 21 provided in the base station body 20 to obtain the cleaning liquid, and then spray the cleaning liquid toward the mopping mechanism of the cleaning apparatus 2.

In particular, the base 30 is configured to carry the cleaning device 2, which in turn may enable the cleaning assembly 31 to be positioned opposite the mopping mechanism. The cleaning assembly 31 may be disposed in the cleaning tank 32, and the first pipeline t1 of the water tank 21 may extend into the cleaning tank 32 to provide cleaning solution, so as to clean the cleaning device 2. The sewage generated after the washing may flow into the washing tank 32, and thus may flow into the sewage tank 24 through the pipe of the sewage tank 24.

Optionally, the base station 1 further includes a switching mechanism 33 disposed on the first pipeline t1 of the liquid supply mechanism 27 and the second pipeline t2 of the air supply mechanism 28, for selectively conducting or switching the first pipeline t1 and the second pipeline t 2. When the second line t2 is turned on, the gas supply mechanism 28 can output the dry gas to the outside through the second line t 2.

For a detailed description of the above-described float assembly 10, reference may be made to the float assembly 10 described in the float assembly embodiments of the present application below.

As shown in fig. 4 to 7, the float assembly 10 includes a float seat 100, a fixing member 200, and a first abutting member 220. The float seat 100 is provided with a liquid inlet cavity 101 and a first liquid outlet 103 for communicating the liquid inlet cavity 101 with the water tank 21. The fixing piece 200 can be movably connected with the float seat 100, and is provided with a liquid inlet channel 201 for receiving liquid inflow and a liquid outlet 202 communicated with the liquid inlet channel 201, wherein the liquid outlet 202 is used for being communicated with the liquid inlet cavity 101. The first abutting piece 220 is disposed on the fixing piece 200, and is used for blocking or opening the first liquid outlet 103.

Wherein the float seat 100 is adapted to be movable between a first position and a second position relative to the fixing member 200 by buoyancy of the liquid in the water tank 21. The first abutment 220 opens the first drain 103 when the float seat 100 is in the first position to allow liquid flowing out through the liquid outlet 202 to flow to the tank 21 through the liquid inlet 101 and the first drain 103. The first abutting piece 220 seals the first liquid outlet 103 when the float seat 100 is at the second position, so as to prevent the liquid flowing out from the liquid outlet 202 from flowing to the water tank 21 through the liquid inlet cavity 101 and the first liquid outlet 103.

The liquid inlet cavity 101 is used for selectively communicating with the water tank 21, and the liquid inlet cavity 101 is communicated with the water tank 21 when the float seat 100 is at the first position, so that the liquid flowing out through the liquid outlet 202 can flow into the water tank 21 through the liquid inlet cavity 101. The liquid inlet cavity 101 is blocked by the first abutting piece 220 when the float seat 100 is at the second position and is not communicated with the water tank 21, so that liquid flowing out through the liquid outlet 202 cannot flow into the water tank 21 through the liquid inlet cavity 101.

When the liquid level in the water tank 21 is below the set threshold, the float assembly 10 allows the liquid flowing out of the liquid inlet channel 201 to flow into the water tank 21 through the first liquid discharge port 103. When the liquid level in the water tank 21 reaches a set threshold, the float assembly 10 is subjected to buoyancy to prevent liquid flowing out of the liquid inlet channel 201 from entering the water tank 21 from the first liquid outlet 103.

In some embodiments, the liquid outlet 202 remains in communication with the liquid inlet chamber 101 during movement of the float seat 100 relative to the mount 200 such that liquid flowing out through the liquid outlet 202 can flow into the liquid inlet chamber 101.

The source of liquid in the tank 21 may flow from the inlet chamber 101 into the tank 21, and during the flow of liquid from the inlet chamber 101 into the tank 21, the level of liquid in the tank 21 increases, causing the float seat 100 to move to the second position. The liquid level decreases when the liquid in the tank 21 is consumed, so that the float seat 100 falls back toward the first position. When the liquid inlet cavity 101 is communicated with the water tank 21, liquid can sequentially pass through the liquid inlet channel 201, the liquid outlet 202 and the liquid inlet cavity 101 and then enter the water tank 21, and the liquid inlet cavity 101 plays a role of a liquid flow channel. When the liquid inlet cavity 101 is blocked by the first abutting piece 220, the liquid enters the liquid inlet cavity 101 from the liquid outlet 202 when the liquid entering the liquid inlet cavity 101 reaches a certain amount due to the limited capacity of the liquid inlet cavity 101.

Specifically, when a pressure difference exists between the liquid inlet channel 201 and the liquid inlet cavity 101, the pressure difference causes the liquid in the liquid inlet channel 201 to enter the liquid inlet cavity 101. When the liquid enters the liquid inlet cavity 101 and cannot be discharged, the pressure in the liquid inlet cavity 101 increases until the liquid is balanced with the pressure in the liquid inlet channel 201, so that the liquid cannot enter the liquid inlet cavity 101 from the liquid outlet 202.

Further, when the liquid inlet cavity 101 is blocked by the first abutting piece 220, gas can exist in the liquid inlet cavity 101, and when liquid enters the liquid inlet cavity 101, the gas can be compressed, so that the air pressure and the hydraulic pressure in the liquid inlet cavity 101 are balanced finally.

In the process of plugging the liquid inlet cavity 101, the pressure in the liquid inlet cavity 101 is gradually increased, compared with the way of directly plugging the liquid outlet 202, the way of plugging the liquid inlet cavity 101 can avoid the situation that the plugging port is not sealed caused by pressure mutation, and the reliability of flow plugging can be improved.

Alternatively, the fixing member 200 is detachably and fixedly provided to the water tank 21 and connected to the inlet pipe 22 such that the inlet channel 201 is stably communicated with the inlet pipe 22.

Alternatively, the float assembly 10 may be assembled with the inlet pipe 22 after completion of assembly, and then integrally assembled to the water tank 21.

The float seat 100 is provided with a liquid inlet cavity 101 and a first liquid outlet 103 used for communicating the liquid inlet cavity 101 with the water tank 21, the fixing piece 200 can be movably connected with the float seat 100, the fixing piece 200 is provided with a liquid inlet channel 201 used for receiving liquid inflow and a liquid outlet 202 communicated with the liquid inlet channel 201, the liquid outlet 202 is used for communicating the liquid inlet cavity 101, the first abutting piece 220 is arranged on the fixing piece 200 and used for blocking or opening the first liquid outlet 103, wherein the float seat 100 is used for being acted by the liquid buoyancy of the water tank 21 and can move between a first position and a second position relative to the fixing piece 200, the first abutting piece 220 is used for opening the first liquid outlet 103 when the float seat 100 is in the first position, so as to allow liquid flowing out through the liquid inlet cavity 101 and the first liquid outlet 103 to flow into the water tank 21, the first abutting piece 220 is used for blocking the first liquid outlet 103 when the float seat 100 is in the second position, the liquid outlet 103 flows out through the liquid inlet cavity 101 and the first liquid outlet 103, when the liquid level in the water tank 21 is lower than the liquid level in the water tank 21, the float seat can be automatically set, the liquid level in the water tank 21 can be prevented from flowing into the water tank 21, the liquid level can be automatically set to the water tank 21 can be prevented from flowing into the water tank 21, the water tank can be stably, and the liquid level can be prevented from flowing into the water tank 21 can be stably, and the liquid level can be stably set in the water tank can be prevented from flowing into the water tank 21 by the liquid tank 21, and the liquid level can be automatically and stable, and the liquid level can be automatically and stable liquid level can be kept in the liquid level can be automatically and stable liquid level can be stable, and the liquid level can be stable, and stable liquid level can and stable.

In some embodiments, when the float seat 100 moves to the state that the liquid inlet cavity 101 is blocked by the first abutting piece 220, the liquid in the liquid inlet cavity 101 can break the blocking of the liquid inlet cavity 101 by the fixing piece 200 and then flow into the water tank 21 due to the pressure in the liquid inlet cavity 101 becoming larger. Then, the liquid level in the water tank 21 will rise, and since the float seat 100 is limited to the second position at this time, the archimedes principle can know that the buoyancy force borne by the float seat 100 will become greater during the rising of the liquid level in the water tank 21, so the blocking effect of the fixing member 200 is improved, and finally the pressure and buoyancy force in the liquid inlet cavity 101 reach an equilibrium state, so that the liquid in the liquid inlet cavity 101 cannot break through the blocking of the fixing member 200 to the liquid inlet cavity 101.

In other embodiments, when the float seat 100 moves to the position where the liquid inlet cavity 101 is blocked by the first abutting member 220, the liquid level in the liquid inlet cavity 101 continues to rise, so that the weight of the liquid becomes large, and the liquid in the liquid inlet cavity 101 can break the blocking of the liquid inlet cavity 101 by the fixing member 200 and then flow into the water tank 21. Then, the liquid level in the water tank 21 will rise, and finally the pressure and the buoyancy in the liquid inlet cavity 101 reach an equilibrium state, so that the liquid in the liquid inlet cavity 101 cannot break through the sealing of the fixing piece 200 to the liquid inlet cavity 101.

Alternatively, the material of the float seat 100 may be a low density foam material. Of course, other materials with a density lower than that of the liquid may be used for the float seat 100.

Alternatively, the inlet chamber 101 communicates with the tank 21 when the float seat 100 is between the first position and the second position.

As shown in fig. 6 and 7, optionally, a portion of the fixing member 200 is disposed in the liquid inlet cavity 101, and the first abutment member 220 is located in the liquid inlet cavity 101.

Further, the first abutment 220 protrudes from the portion of the fixing member 200 located in the liquid inlet cavity 101, and the first abutment 220 is limited in the liquid inlet cavity 101. The first abutting piece 220 is spaced apart from the first liquid discharge port 103 when the float seat 100 is in the first position to open the first liquid discharge port 103. The first abutment 220 seals the first drain 103 in the liquid inlet chamber 101 when the float seat 100 is in the second position.

The fixing piece 200 is partially arranged in the liquid inlet cavity 101, and can limit the float seat 100 when the float seat 100 moves relative to the fixing piece 200 so as to prevent the float seat 100 from deviating from the liquid inlet cavity 101, thereby ensuring the blocking effect. The fixing member 200 is partially disposed in the liquid inlet chamber 101, and can also reduce the volume of the float assembly 10 to increase the amount of liquid stored in the water tank 21, which has the advantage of small volume compared to the conventional float valve float.

During the process of liquid flowing from the liquid inlet cavity 101 to the water tank 21 through the first liquid outlet 103, the float seat 100 moves to the second position, so that the first abutting piece 220 seals the first liquid outlet 103 in the liquid inlet cavity 101. When the liquid level in the water tank 21 drops, the first abutting piece 220 and the first liquid outlet 103 are far away from each other until the float seat 100 moves to the first position, the first abutting piece 220 and the first liquid outlet 103 are arranged at intervals, and at this time, the first liquid outlet 103 is communicated with the liquid inlet cavity 101 and the water tank 21.

Optionally, the outer peripheral dimension of the first liquid outlet 103 is smaller than the outer peripheral dimension of the first abutting piece 220, so that the first abutting piece 220 cannot pass through the first liquid outlet 103, and therefore the first abutting piece 220 is limited in the liquid inlet cavity 101.

Further, the first abutment 220 is provided at the outer periphery of the fixing member 200.

Alternatively, the float seat 100 is sleeved on the fixing member 200 when the float assembly 10 is installed for use. With the change of the liquid level in the water tank 21, the float seat 100 is slidable along the length direction of the fixing member 200 under the action of buoyancy or self gravity.

Alternatively, as the fixing member 200 and the float seat 100 slide relatively, the portion of the fixing member 200 located within the float seat 100 may be changed, and accordingly the shape of the liquid inlet chamber 101 may be changed.

Alternatively, the fixing member 200 is slidably disposed through the float seat 100 in the length direction through the first drain port 103. When the float seat 100 is at the first position, the liquid inlet cavity 101 is communicated with the outside through a gap between the inner wall of the first liquid outlet 103 and the fixing piece 200. At this time, the liquid in the liquid inlet chamber 101 flows to the outside through the gap between the inner wall of the first liquid outlet 103 and the fixing member 200. When the float seat 100 is at the second position, the gap between the inner wall of the first liquid discharge port 103 and the fixing member 200 is blocked by the first abutting member 220 from communicating with the outside. At this time, the inlet chamber 101 is blocked from communication with the outside.

Optionally, the fixing member 200 is further provided with a liquid inlet 206, and the liquid inlet 206 is communicated with the liquid inlet channel 201 and is used for receiving liquid input, so that the liquid flows from the liquid inlet 206 into the liquid inlet cavity 101 through the liquid inlet channel 201 and the liquid outlet 202 in sequence. The liquid inlet 206 may be in communication with the liquid inlet tube 22 such that liquid may enter the liquid inlet channel 201 through the liquid inlet tube 22 via the liquid inlet 206.

In other embodiments, when the float seat 100 is in the first position, the liquid outlet 202 is located outside the liquid inlet chamber 101, and the liquid can flow out of the liquid outlet 202 and then fall into the liquid inlet chamber 101.

Alternatively, the float seat 100 includes a first step 120. When the float seat 100 is at the first position, the first abutting piece 220 and the first step portion 120 are spaced apart from each other to open the first liquid drain 103. When the float seat 100 is at the second position, the first abutting piece 220 abuts against the first step portion 120 to block the first liquid drain 103.

Further, a first step 120 is provided at a communication point between the first drain 103 and the liquid inlet 101.

During the process of flowing the liquid from the liquid inlet cavity 101 into the water tank 21 through the first liquid outlet 103, the float seat 100 moves to the second position, so that the first abutting piece 220 and the first step portion 120 approach each other, and finally the first abutting piece 220 abuts against the first step portion 120. When the liquid level in the water tank 21 drops, the float seat 100 moves to the first position, so that the first abutment 220 and the first step 120 are away from each other, and then the first abutment 220 and the first step 120 are spaced apart.

Alternatively, the fixing member 200 includes a rod-shaped body 230 and a first boss 221. The liquid inlet channel 201 and the liquid outlet 202 are formed in the rod-shaped body 230. The first boss 221 is convexly provided at the outer circumference of the rod-shaped body 230. Wherein, the first abutting piece 220 is coated on the periphery of the first protruding portion 221.

The first protrusion 221 may provide support for the first abutment 220 when the first abutment 220 abuts the first step 120. The first abutment 220 may be located between the first boss 221 and the first step 120 to have a sealing effect. The first abutting piece 220 is wrapped on the outer periphery of the first protruding portion 221, so that the first abutting piece 220 can be fixed.

Optionally, the rod-shaped body 230 may be provided with a liquid inlet 206. Further, the liquid inlet 206 may be formed at one end of the rod-shaped body 230. The liquid inlet channel 201 may extend along the axial direction of the rod-shaped body 230, and the liquid inlet 206 and the liquid inlet channel 201 may be coaxially arranged with the rod-shaped body 230.

Optionally, the first abutment member 220 is an elastic member, and when the float seat 100 is in the second position, the first abutment member 220 elastically abuts against the inner wall of the float seat 100 to seal the first drain 103.

Optionally, the first abutment 220 is made of an elastic material, such as silicone, rubber, etc. The elastic material is selected to enhance the sealing effect and facilitate the cladding installation of the first abutting element 220.

Alternatively, the first abutment 220 includes a first elastic coating portion 223 and a first elastic sealing portion 224 connected to the first elastic coating portion 223. The first elastic coating portion 223 is circumferentially coated on the outer circumference of the first boss 221. The first elastic sealing portion 224 is sleeved on the outer periphery of the rod-shaped body 230, and extends from the second elastic coating portion 213 in a direction away from the second protruding portion 211.

Alternatively, the first protrusion 221 is in the shape of an annular column, the inner ring of the first protrusion 221 is connected to the rod-shaped body 230, and the first elastic coating portion 223 may coat the remaining three surfaces of the first protrusion 221.

Alternatively, the first elastic sealing portion 224 is configured to be elastically deformable, thereby generating pressure on the contact surface with the first stepped portion 120. For example, the first elastic sealing portion 224 has two second elastic arms 226 that are elastically foldable, one end of the two second elastic arms 226 being connected and the other end being remote. The other end of one of the second elastic arms 226 surrounds the first elastic coating portion 223 and is connected to the first elastic coating portion 223, and the other second elastic arm 226 can be abutted against the first step portion 120. In some embodiments, the two second resilient arms 226 are integrally formed together, and have a "U" shaped cross-section in a plane passing through the central axis.

Alternatively, the first elastic sealing portion 224 is spaced apart from the first stepped portion 120 when the float seat 100 is in the first position. When the float seat 100 is at the second position, the first elastic sealing portion 224 abuts against the first step portion 120 to close the first liquid outlet 103.

During the process of flowing the liquid from the liquid inlet cavity 101 into the water tank 21 through the first liquid outlet 103, the float seat 100 moves to the second position, so that the first elastic sealing portion 224 and the first step portion 120 approach each other, and finally the first elastic sealing portion 224 abuts against the first step portion 120. When the liquid level in the water tank 21 drops, the float seat 100 moves to the first position, so that the first elastic sealing portion 224 and the first step portion 120 are away from each other, and then the first elastic sealing portion 224 and the first step portion 120 are spaced apart from each other.

Alternatively, the first step portion 120 is disposed in a frustum shape, one end of which is connected to the inner wall of the liquid inlet cavity 101, and the other end of which is connected to the inner wall of the first liquid outlet 103.

Alternatively, the first step portion 120 is disposed in a frustum shape, one end of which is connected to the inner wall of the liquid inlet cavity 101, and the other end of which is connected to the inner wall of the first liquid outlet 103. Compared with the right-angle-shaped steps, the frustum-shaped steps can reduce the angle of direction conversion when the liquid flows into the first liquid outlet 103 from the liquid inlet cavity 101, and are beneficial to smooth flow of the liquid.

Alternatively, the angle of the cone mesa to the axis may be from 20 degrees to 80 degrees, such as 30 degrees, 45 degrees or 60 degrees.

Optionally, the float seat 100 is further provided with a second liquid outlet 102 communicated with the liquid inlet cavity 101, and the second liquid outlet 102 is spaced from the first liquid outlet 103.

When the float seat 100 is at the first position, the liquid inlet cavity 101 is communicated with the water tank 21 through the second liquid outlet 102 and the first liquid outlet 103. When the float seat 100 is in the second position, both the second liquid discharge port 102 and the first liquid discharge port 103 are blocked so that the liquid inlet chamber 101 is not communicated with the water tank 21.

In the process that the liquid in the liquid inlet cavity 101 flows into the water tank 21 through the first liquid outlet 103, a gap between the inner wall of the second liquid outlet 102 and the fixing piece 200 can be used as an air flow channel, so that the air pressure in the liquid inlet cavity 101 is balanced with the air pressure in the water tank 21.

In the process that the liquid in the liquid inlet cavity 101 flows into the water tank 21 through the first liquid outlet 103, if the flow rate of the liquid in the liquid inlet channel 201 is greater than the flow rate at the first liquid outlet 103, the liquid can flow into the water tank 21 through the gap between the inner wall of the second liquid outlet 102 and the fixing piece 200.

In some embodiments, when a portion of the fixing member 200 is disposed in the liquid inlet cavity 101 through the second liquid outlet 102, correspondingly, the liquid in the liquid inlet channel 201 passes through the liquid inlet channel 201 and enters the liquid inlet cavity 101 through the second liquid outlet 102.

Optionally, the float assembly 10 further includes a second abutment 210, where the second abutment 210 is disposed on the fixing member 200 and spaced apart from the first abutment 220.

When the float seat 100 is in the second position, the second abutment 210 seals the second drain 102.

During the process of flowing the liquid from the liquid inlet cavity 101 into the water tank 21 through the first liquid outlet 103, the float seat 100 moves to the second position, so that the second abutting piece 210 and the second liquid outlet 102 are close to each other, and finally the second abutting piece 210 seals the second liquid outlet 102. When the liquid level in the water tank 21 drops, the float seat 100 moves to the first position, so that the second abutting piece 210 and the second liquid outlet 102 are far away from each other, and then the second liquid outlet 102 is communicated with the liquid inlet cavity 101 and the water tank 21.

Alternatively, the second abutment 210 is provided at the outer circumference of the fixing member 200.

Alternatively, the float seat 100 may include an upper end float 106 and a lower end float 107, the upper end float 106 and the lower end float 107 being connected by ultrasonic welding. The second liquid outlet 102 may be opened to the upper float 106, and the first liquid outlet 103 may be opened to the lower float 107. The upper end float 106 and the lower end float 107 may form the inlet chamber 101 after being connected.

Optionally, the second abutment 210 is located outside the float seat 100.

Further, the second abutment 210 is located outside the liquid inlet chamber 101. When the float seat 100 is at the first position, the second abutting piece 210 and the outer periphery of the float seat 100 surrounding the second liquid outlet 102 are spaced apart from each other so as to open the second liquid outlet 102. The second abutment 210 abuts the outer peripheral edge when the float seat 100 is in the second position.

When the float seat 100 is at the first position, the second abutting piece 210 and the float seat 100 enclose the outer periphery of the second liquid outlet 102 to be spaced from each other, and the first abutting piece 220 and the first liquid outlet 103 are spaced from each other, so that the second liquid outlet 102 and the first liquid outlet 103 are both communicated with the liquid inlet cavity 101 and the water tank 21. When the float seat 100 is at the second position, the second abutting piece 210 abuts against the outer periphery of the second liquid outlet 102 surrounded by the float seat 100 outside the liquid inlet cavity 101, and the first abutting piece 220 seals the first liquid outlet 103 inside the liquid inlet cavity 101.

Alternatively, the upper end float 106 may have a second step 110 and the lower end float 107 may have a first step 120.

When the float seat 100 is at the first position, the first abutting piece 220 abuts against the second step portion 110 or is arranged at intervals from both the second step portion 110 and the first step portion 120, and the second abutting piece 210 is arranged at intervals from the second liquid drain port 102 away from the periphery of the second step portion 110. When the float seat 100 is at the second position, the first abutting piece 220 abuts against the first step portion 120 to block the first liquid outlet 103, and the second abutting piece 210 abuts against the second liquid outlet 102 away from the periphery of the second step portion 110 to block the second liquid outlet 102.

In some embodiments, the inner ring size of the second step portion 110 is smaller than the outer circumference size of the first abutment member 220, so when the second step portion 110 is far away from the second abutment member 210, the first abutment member 220 can abut against the second step portion 110 to limit the float seat 100 to the first position. In other embodiments, the float seat 100 is limited at the first position during the process of moving the second step portion 110 away from the second abutment member 210, and the first abutment member 220 is spaced apart from both the second step portion 110 and the first step portion 120.

During the process of flowing the liquid from the liquid inlet cavity 101 into the water tank 21 through the first liquid outlet 103, the float seat 100 moves to the second position, so that the second abutting piece 210 and the second liquid outlet 102 are close to each other away from the periphery of the second step portion 110, meanwhile, the first abutting piece 220 and the first step portion 120 are close to each other, finally, the second abutting piece 210 abuts against the periphery of the second liquid outlet 102 away from the second step portion 110, and the first abutting piece 220 abuts against the first step portion 120. When the liquid level in the water tank 21 drops, the float seat 100 moves to the first position, so that the second abutting piece 210 and the second liquid outlet 102 are far away from the periphery of the second step portion 110, and meanwhile, the first abutting piece 220 and the first step portion 120 are far away from each other, and then the first abutting piece 220 and the first step portion 120 are arranged at intervals, and the second abutting piece 210 and the second liquid outlet 102 are far away from the periphery of the second step portion 110 at intervals.

Optionally, when the float seat 100 is at the second position, the liquid level in the liquid inlet cavity 101 is higher than the bottom surface of the second step portion 110, so that the second step portion 110 is subjected to upward buoyancy at the bottom surface, and the buoyancy can resist the pressure of the second abutment member 210 on the second step portion 110 at the periphery of the second liquid outlet 102 far from the second step portion 110, which is beneficial to improving the sealing effect.

Alternatively, the fixing member 200 includes a rod-shaped body 230 and a second boss 211. The liquid inlet channel 201 and the liquid outlet 202 are formed in the rod-shaped body 230. The second protrusion 211 is convexly provided at the outer circumference of the rod-shaped body 230. The first abutting piece 220 is disposed on the rod-shaped body 230.

The second protruding portion 211 may provide support for the second abutment 210 when the second abutment 210 abuts against the second step portion 110. The second abutment 210 may be located between the second raised portion 211 and the second stepped portion 110 to have a sealing effect. The second abutting piece 210 is wrapped on the outer periphery of the second protruding portion 211, so that the second abutting piece 210 can be fixed.

Alternatively, the second protrusion 211 and the first protrusion 221 are disposed at intervals along the length direction of the rod-shaped body 230 in the rod-shaped body 230.

Optionally, the second abutment 210 is made of an elastic material, such as silicone, rubber, etc. The elastic material is selected to not only enhance the sealing effect, but also facilitate the cladding installation of the second abutting piece 210.

Alternatively, the second abutment 210 includes a second elastic coating 213 and a second elastic sealing portion 214 connected to the second elastic coating 213. The second elastic coating portion 213 is circumferentially coated on the outer periphery of the second protrusion portion 211. The second elastic sealing portion 214 is sleeved on the outer periphery of the rod-shaped body 230, and extends from the second elastic coating portion 213 in a direction away from the second protruding portion 211.

The second elastic sealing portion 214 is spaced apart from the outer peripheral edge when the float seat 100 is in the first position. The second elastic sealing portion 214 abuts against the outer peripheral edge when the float seat 100 is in the second position.

During the process of flowing the liquid from the liquid inlet cavity 101 into the water tank 21 through the first liquid outlet 103, the float seat 100 moves to the second position, so that the second elastic sealing portion 214 and the outer periphery are close to each other, meanwhile, the first elastic sealing portion 224 and the first step portion 120 are close to each other, finally, the second elastic sealing portion 214 abuts against the outer periphery, and the first elastic sealing portion 224 abuts against the first step portion 120. When the liquid level in the water tank 21 drops, the float seat 100 moves to the first position, so that the second elastic sealing portion 214 is away from the outer periphery, and meanwhile, the first elastic sealing portion 224 is away from the first step portion 120, so that the first elastic sealing portion 224 is spaced from the first step portion 120, and the second elastic sealing portion 214 is spaced from the outer periphery.

Optionally, the second protruding portion 211 is an annular column, the inner ring of the second protruding portion 211 is connected to the rod-shaped body 230, and the second elastic coating portion 213 may cover the remaining three surfaces of the second protruding portion 211.

Alternatively, the second elastic sealing portion 214 is configured to be elastically deformable, thereby generating pressure on the contact surface with the second stepped portion 110. For example, the second elastic sealing portion 214 has two first elastic arms 225 that are elastically foldable, one end of the two first elastic arms 225 being connected and the other end being remote. The other end of one of the first elastic arms 225 surrounds the second elastic coating portion 213 and is connected to the second elastic coating portion 213, and the other first elastic arm 225 can abut against the second step portion 110. In some embodiments, the two first resilient arms 225 are integrally formed, and have a "U" shaped cross-section in a plane passing through the central axis.

Alternatively, when the float seat 100 is at the first position, the second elastic sealing portion 214 is spaced apart from the periphery of the second liquid drain port 102 away from the second step portion 110, and the first elastic sealing portion 224 is spaced apart from the first step portion 120. When the float seat 100 is at the second position, the second elastic sealing portion 214 abuts against the periphery of the second liquid outlet 102 far from the second step portion 110 to seal the second liquid outlet 102, and the first elastic sealing portion 224 abuts against the first step portion 120 to seal the first liquid outlet 103.

Alternatively, the second liquid outlet 102 and the first liquid outlet 103 are respectively disposed at two ends of the liquid inlet cavity 101, and the fixing member 200 is disposed through the second liquid outlet 102, the liquid inlet cavity 101 and the first liquid outlet 103 and is disposed on the float seat 100. The second drain 102 is located between the first abutment 220 and the second abutment 210. The outlet 202 is configured at least to: when the float seat 100 is in the second position, the liquid outlet 202 is located within the float seat 100.

Further, the liquid outlet 202 is located between the first abutting piece 220 and the second abutting piece 210, and is closer to the first abutting piece 220 than the second abutting piece 210.

When the float seat 100 is at the first position, the liquid inlet chamber 101 communicates with the water tank 21 through the gap between the inner walls of the second liquid outlet 102 and the first liquid outlet 103 and the fixing member 200.

Alternatively, the second liquid outlet 102 and the first liquid outlet 103 are disposed opposite to each other along the length direction of the fixing member 200, and the fixing member 200 is slidably disposed through the float seat 100 along the length direction of the fixing member 200 via the second liquid outlet 102 and the first liquid outlet 103.

Further, the second liquid outlet 102, the liquid inlet chamber 101 and the first liquid outlet 103 may be sequentially distributed along the length direction of the fixing member 200.

When the float assembly 10 is installed for use, the float seat 100 is sleeved on the fixing member 200. With the change of the liquid level in the water tank 21, the float seat 100 is slidable along the length direction of the fixing member 200 under the action of buoyancy or self gravity. As the fixing member 200 and the float seat 100 slide relatively, the portion of the fixing member 200 located within the float seat 100 may change, and accordingly the shape of the liquid inlet chamber 101 may also change.

Optionally, the liquid inlet chamber 101 is located between the second liquid outlet 102 and the first liquid outlet 103, and the outer peripheral dimensions of the second liquid outlet 102 and the first liquid outlet 103 are smaller than the outer peripheral dimensions of the first abutting piece 220, so that the first abutting piece 220 cannot pass through the second liquid outlet 102 or the first liquid outlet 103, and therefore the first abutting piece 220 is limited in the liquid inlet chamber 101.

Alternatively, the liquid outlet 202 is located between the second boss 211 and the first boss 221 such that the liquid inlet chamber 101 surrounds the liquid outlet 202 when the float seat 100 is in the second position. The liquid outlet 202 is closer to the first boss 221 than the second boss 211 can shorten the travel of the liquid into the tank 21. When the float seat 100 is in the first position, the liquid outlet 202 is located in the second liquid outlet 102 or in the liquid inlet cavity 101, and liquid can enter the liquid inlet cavity 101 through the second liquid outlet 102 or directly enter the liquid inlet cavity 101. When the float seat 100 is in the second position, the liquid outlet 202 is located in the liquid inlet cavity 101. Thus, the outlet 202 may be stopped from flowing out of the liquid by blocking the inlet chamber 101.

Optionally, the float assembly 10 further comprises a blocking member 300, the blocking member 300 being connected to the fixing member 200 and adapted to hold the float seat 100. Specifically, the stopper 300 is used to support the float seat 100 in a state where the float seat 100 is not subjected to the buoyancy of the liquid, and the float seat 100 falls down onto the stopper 300 based on its own weight in a state where the float seat 100 is not subjected to the buoyancy of the liquid.

Optionally, a blocking member 300 may be disposed at an end of the rod-shaped body 230 remote from the fluid inlet 206, which may further prevent the float seat 100 from being disengaged from the fixing member 200 during movement relative to the fixing member 200.

Optionally, the blocking member 300 includes a connection portion 310 and a blocking portion 320, and an end portion of the fixing member 200, specifically, an end of the fixing member 200 remote from the second liquid outlet 102 is provided with a connection hole 203 mated with the connection portion 310, and an end of the connection portion 310 is connected in the connection hole 203. The blocking part 320 is disposed at the other end of the connecting part 310, and the blocking part 320 is located outside the liquid inlet cavity 101 and is used for supporting the float seat 100.

Specifically, one end of the connection portion 310 has an external thread, and the connection hole 203 has an internal thread therein, and the connection portion 310 is screwed with the connection hole 203. When the blocking member 300 is connected with the fixing member 200, the blocking portion 320 is at the other end of the fixing member 200, and when the float seat 100 is at the second position, the blocking portion 320 abuts against the float seat 100, preventing the float seat 100 from being separated from the fixing member 200.

Alternatively, the connection hole 203 extends in the axial direction of the fixing member 200, and the blocking member 300 and the fixing member 200 may be coaxially connected.

Optionally, the blocking portion 320 is located outside the first drain 103. In order to prevent the blocking portion 320 from blocking the gap between the inner wall of the first drain port 103 and the fixing member 200, the float seat 100 may be provided with a capacity expansion channel 208, and the capacity expansion channel 208 communicates between the first drain port 103 and the water tank 21. Further, the float seat 100 is circumferentially distributed with a plurality of expansion passages 208. It will be appreciated that in other embodiments, the blocking member 300 may be omitted, and the first abutment member 220 may be used to hold the float seat 100 to prevent the float seat 100 from being separated from the fixing member 200.

Optionally, the number of the liquid outlets 202 is at least two, and the at least two liquid outlets 202 are disposed on the fixing member 200 at intervals along the length direction and/or the circumferential direction of the fixing member 200. The number of the liquid outlets 202 may be two, three or four or more, and the plurality of liquid outlets 202 are circumferentially spaced. Further, at least two of the liquid outlets 202 are uniformly distributed in the circumferential direction. For example, the number of the liquid outlets 202 is two, the two liquid outlets 202 are arranged at intervals along the circumferential direction of the fixing piece 200, the central connecting line of the two liquid outlets 202 passes through the central axis of the fixing piece 200, and the flowing directions of the liquid at the two liquid outlets 202 are opposite, so that the acting forces of the liquid entering the liquid inlet cavity 101 and the float seat 100 and the fixing piece 200 can be offset, and meanwhile, the acting forces between the liquid at the two liquid outlets 202 can also be offset, so that the flowing of the liquid is smoother.

Optionally, the fixing member 200 may be provided with at least two liquid outlet channels 207, and each liquid outlet channel 207 communicates with the liquid inlet channel 201 and one liquid outlet 202. The liquid can flow from the liquid inlet channel 201 to the liquid outlet channel 207 and then to the liquid outlet 202. The axis of the liquid outlet channel 207 forms an angle of 30 degrees to 90 degrees with the axis of the fixing member 200. Further, the angle between the axis of the liquid outlet channel 207 and the axis of the fixing member 200 is 90 degrees.

The liquid outlet 202 may be formed on the outer peripheral side of the fixing member 200, and an included angle exists between the liquid flowing direction at the liquid outlet 202 and the axial direction of the fixing member 200, so that the liquid at the liquid outlet 202 does not directly impact the float seat 100 in the axial direction of the fixing member 200. Because the float seat 100 moves along the axial direction of the fixing piece 200 to block or unblock the liquid inlet cavity 101, the liquid outlet 202 is formed on the side surface of the outer periphery of the fixing piece 200, so that the impact of the liquid at the liquid outlet 202 can be prevented from affecting the blocking of the liquid inlet cavity 101.

In some embodiments, the number of the liquid outlets 202 is two, each group of liquid outlets 202 is evenly distributed along the circumferential direction, and the two groups of liquid outlets 202 are distributed along the length direction. In other embodiments, the number of the liquid outlets 202 is three, each group has two liquid outlets 202, each group has a uniform interval distribution along the circumferential direction, and the three groups of liquid outlets 202 have an interval distribution along the length direction.

The limiting rib 205 may be disposed at the outer circumference of the fixing member 200. The stop rib 205 may also function as a guide in the length direction.

Alternatively, the fixing member 200 is provided with guide ribs 204 extending in the length direction of the fixing member 200, and the guide ribs 204 are disposed at intervals in the circumferential direction of the fixing member 200. The guide rib 204 is used to cooperate with the inner wall of the second liquid outlet 102 to guide the relative sliding of the float seat 100 in the length direction of the fixing member 200.

The guide rib 204 may be provided at the outer circumference of the fixing member 200. By arranging the guide rib 204, the surface contact between the fixing piece 200 and the inner wall of the second liquid outlet 102 can be converted into line contact, the distance between the periphery of the fixing piece 200 and the inner wall of the second liquid outlet 102 is increased while the float seat 100 is kept from sliding and not deflecting, and the relative sliding of the fixing piece 200 and the float seat 100 in liquid is facilitated.

Alternatively, during assembly of the float assembly 10, the second abutment 210 may be first wrapped around the second boss 211, then the upper end float 106 is installed (fig. 9), then the first abutment 220 is wrapped around the first boss 221 (fig. 10), and finally the lower end float 107 is assembled and the lower end float 107 is connected to the upper end float 106 (fig. 11).

In some embodiments, installation of barrier 300 may be performed after lower end float 107 is assembled, connecting barrier 300 to mount 200 (fig. 11).
