Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment, and particularly relates to a water tank and a cleaning equipment. Background Art

[0002] Existing cleaning equipment generally needs to be equipped with a water tank. However, in existing cleaning equipment, the clean water tank and the sewage tank are generally arranged independently. The dirty liquid generated after the cleaning liquid in the clean water tank is discharged for operation is sucked into the sewage tank. As the cleaning work progresses, the cleaning liquid in the clean water tank gradually decreases, and the dirty liquid in the sewage tank gradually increases. The clean water tank and the sewage tank will not be filled at the same time, resulting in a waste of the volume space of the water tank. And the water tank usually occupies a large space of the cleaning equipment, making the cleaning equipment large in volume, which easily limits the passability of the cleaning equipment and has high requirements for the space of the use environment, especially not conducive to use in a narrow space. But if the water storage capacity is sacrificed and a small-volume water tank is used to keep the cleaning equipment small in volume, it will result in a small amount of cleaning water per unit area, or the need to frequently add cleaning liquid to the water tank of the cleaning equipment and discharge the dirty liquid, resulting in a deterioration of the cleaning effect or user experience.

Specific embodiments

[0071] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

[0072] It should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the conditions under which the present utility model can be implemented. Therefore, they do not have any substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are only for the convenience of clear narration, and are not used to limit the scope in which the present utility model can be implemented. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope in which the present utility model can be implemented.

[0073] See Figures 1 to 5 、 Figure 12 and Figure 13 , in some alternative embodiments, the present application provides a water tank, including a first box body 1 and a second box body 2. The second box body 2 is installed inside the first box body 1; the second box body 2 has a first chamber 23, and a second chamber 11 is formed between the outer wall of the second box body 2 and the inner wall of the first box body 1; wherein, the second box body 2 includes a rigid part 22 and a flexible part 21, the rigid part 22 and the flexible part 21 are connected to enclose the first chamber 23, and the flexible part 21 can deform to change the volume ratio of the first chamber 23 and the second chamber 11.

[0074] The rigid part can be made of a material that is less likely to deform when subjected to the force of a fluid, and the flexible part can be made of a material that is more likely to deform when subjected to the force of a fluid, so that the flexible part can deform when subjected to the force of the liquid in the first chamber or the second chamber, changing the volume ratio of the first chamber and the second chamber.

[0075] Optionally, the flexible part 21 can be a component with a flexible deformation function or an elastic deformation function. It can be understood that the flexible deformation function means that the flexible part 21 can undergo flexible deformation, but the surface area of the flexible part 21 will not change, will not be stretched, and is not easily torn. The elastic deformation function means that the flexible part 21 can undergo elastic deformation, and the flexible part 21 can expand under the action of an external force to increase the surface area of the flexible part 21. When the external force disappears, the surface area of the flexible part 21 shrinks back to the initial state. The shape structure and the material used for the flexible part 21 can be flexibly selected according to requirements.

[0076] For example, the structure of the second box body formed by the rigid part 22 and the flexible part 21 is as Figure 3 shown. When there is liquid in the first chamber 23 and no liquid in the second chamber 11, affected by the force of the liquid in the first chamber 23, the flexible part 21 is in Figure 3In this state, as the liquid contained in the second chamber 11 increases, the liquid in the second chamber 11 also exerts a force on the flexible part 21. For any position of the flexible part, the first force exerted by the liquid in the second chamber 11 on the flexible part 21 points to the first chamber 23, and the second force exerted by the liquid in the first chamber 23 on the flexible part 11 points to the second chamber 11; when the first force is greater than the second force, the flexible part deforms and depresses into the first chamber 23, causing the volume of the second chamber 11 to decrease and the volume of the first chamber 23 to increase, thereby changing the volume ratio of the first chamber 23 and the second chamber 11. The above is only an example and does not constitute a specific limitation on the solution provided by the embodiments of the specification. Figure 3 The state towards the first chamber 23 causes the volume of the second chamber 11 to decrease and the volume of the first chamber 23 to increase, changing the volume ratio of the first chamber 23 and the second chamber 11. The above is only an example and does not constitute a specific limitation on the solution provided by the embodiments of the specification.

[0077] The arrangement and connection method of the rigid part 22 and the flexible part 21 in the second box body 2 are not limited. For example, the rigid part can be a shell with an opening, and the flexible part covers at least part of the rigid part and the entire opening of the rigid part; alternatively, the second box body 2 includes multiple unconnected rigid parts, the flexible part is arranged between the rigid parts, and the flexible part and the rigid part are fixed by screws or glue to form the first chamber 23.

[0078] It can be set that the volume of the first box body 1 cannot change. For example, the first box body 1 is entirely a rigid part; the first box body 1 can also not be limited to being entirely a rigid part. The cleaning device is usually configured with a storage chamber for the water tank, and the inner wall of the storage chamber is entirely a rigid part, which is used to limit the volume of the first box body 1 from changing. Of course, it can also be set that the volume of the first box body 1 can change to change the overall volume of the water tank according to the demand for the overall liquid contained in the water tank; correspondingly, changing the volume ratio of the first chamber 23 and the second chamber 11 can mean that when the volume of the first box body 1 is fixed at a certain value, as the flexible part 21 deforms, the volume of the first chamber 23 increases and the volume of the second chamber 11 decreases; or, when the volume of the first box body 1 is fixed at a certain value, as the flexible part 21 deforms, the volume of the first chamber 23 decreases and the volume of the second chamber 11 increases.

[0079] The water tank and the cleaning device can be a separable structure. The water tank can also be fixed in the cleaning device. For example, the shell of the first box body 1 can be formed by the wall of the storage chamber of the water tank of the cleaning device.

[0080] The second box body 2 is detachably installed in the first box body 1, which is convenient for disassembly and assembly and facilitates taking out the second box body 2 for cleaning the first box body 1 or the second box body 2. After the cleaning device has been performing cleaning for a period of time, dirt residues are likely to remain on the walls of the first box body 1 and / or the second box body 2 and the functional mechanisms in the water tank. If not cleaned thoroughly, it is easy to get moldy and smelly. By detachably installing the second box body 2 in the first box body 1, it is convenient for users to take out the second box body 2 to clean the first box body 1, the second box body 2 and the functional mechanisms in the water tank, effectively reducing the phenomenon of the water tank getting moldy and smelly. At the same time, taking out the second box body 2 also facilitates the maintenance of the functional mechanisms in the water tank. Of course, the second box body 2 can also be fixedly installed in the first box body 1, which is not limited here.

[0081] One of the first chamber 11 and the second chamber 23 is used to hold the cleaning liquid, and the other is used to hold the dirty liquid.

[0082] For example, the water tank can be installed on the cleaning robot. The cleaning liquid can be, for example, clean water, or a cleaning liquid added with a bactericide or a dirt remover, which is not limited. The cleaning liquid in the water tank can be added to the mop of the cleaning robot to perform floor cleaning. The dirty liquid can be, for example, the dirty liquid suctioned from the mop of the cleaning robot. Generally, during the cleaning process of the cleaning robot on the ground, the cleaning liquid gradually decreases and the dirty liquid gradually increases. Based on the water tank provided in the embodiments of this specification, the second box body has a soft part, and the soft part can be flexibly deformed so that the volume ratio between the first chamber and the second chamber can change relatively. When one of the first chamber and the second chamber is used to hold the cleaning liquid and the other is used to hold the dirty liquid, the above structure can make the volume of the chamber holding the cleaning liquid gradually decrease and the volume of the chamber holding the dirty liquid gradually increase, so as to meet the cleaning requirements and improve the user experience without changing the overall volume of the water tank. Of course, the above scenario examples are only preferred examples for illustration and do not constitute a limitation on the solutions of the embodiments of this specification. For example, the water tank can also be installed on the cleaning base station.

[0083] The water tank provided in the embodiments of this specification not only ensures the liquid storage capacity to meet the cleaning requirements, but also saves the space required by the water tank for the cleaning device. Moreover, in the water tank of the above embodiments, the second box body 2 is installed in the first box body 1, making the second box body 2 relatively independent of the first box body 1 and making the installation of the box body more flexible. For example, the second box body 2 can be fixedly connected or detachably connected to the first box body 1. In addition, the second box body 2 has a hard part 22, and the shape and structure of the hard part 22 are stable, which can serve as an installation carrier to provide a stable installation space and support for the components, facilitating improving the overall reliability of the water tank.

[0084] See Figure 3 、 Figure 5 、Figure 8 and Figure 9 In some optional embodiments, the hardware part 22 has a first accommodating area 231 with a first opening 224 at one end, and the software part 21 is arranged at the first opening 224, and the first accommodating area 231 and the software part 21 form a first chamber 23; when the software part 21 is recessed in the first accommodating area 231, the hardware part 22 has an installation part staggered from the software part 21, and the installation part is for installing the functional mechanism of the first chamber 23 and / or the second chamber 11.

[0085] Functional mechanisms may refer to water pipes, liquid level detection mechanisms, valves, gas-liquid separation structures, control circuits, and the like. When the soft part is deformed, it may interfere with the functional mechanism in the water tank, causing damage to the soft part, or the soft part may affect the normal operation of the valve, liquid level detection mechanism, and gas-liquid separation structure. The water tank of this embodiment is arranged such that when the soft part 21 is recessed in the first accommodating area 231, the hard part 22 has an installation portion staggered from the soft part 21, and the installation portion is provided for the functional mechanism of the first chamber 23 and / or the second chamber 11 to be installed, thereby avoiding the soft part 21 from interfering with the functional mechanism, ensuring the normal operation of the functional mechanism, and avoiding possible damage to the soft part, thereby improving the reliability of the water tank.

[0086] The soft portion 21 may be a film covering the first opening 224 .

[0087] Alternatively, the soft body 21 may also be formed with a cavity, such as a soft bag, a soft shell or other structures with a cavity, see Figure 3 , Figure 5 , Figure 8 and Figure 9 In some optional embodiments, when the software part 21 is not recessed in the first accommodating area 231, the software part 21 has a second accommodating area 232 with a second opening 211 at one end, and the second opening 211 of the software part 21 is sealed and connected to the first opening 224 of the hardware part 22; and the first accommodating area 231 and the second accommodating area 232 are connected to form a first chamber 23.

[0088] Optionally, the hardware part 22 and the software part 21 can be sealed by bonding, locking parts or other connection methods. Further, part of the software part 21 is covered on the part of the hardware part 22 protruding from the edge of the first opening 224, and then the software part 21 and the hardware part 22 are locked with screws so that the part of the software part 21 connected to the hardware part 22 is squeezed to form a seal, and the soft material of the software part 21 itself is used to achieve the seal, the structure is simple, and the sealing connection is simple and convenient; or, the software part 21 and the hardware part 22 are sealed by applying glue and locking parts, and the sealing connection is reliable.

[0089] For the water tank of the above embodiment, the flexible part 21 has a structural form that can form a cavity, which can further increase the deformation space of the flexible part 21. The deformation of the flexible part 21 is a flexible deformation, which not only has low requirements for the material of the flexible part 21, but also helps to reduce the risks of the flexible part 21 being pulled, torn and damaged, avoid the long-term deformation of the flexible part 21 from falling off the rigid part 22, and is beneficial to extending the service life.

[0090] See Figure 1 、 Figure 3 、 Figure 5 、 Figure 8 and Figure 9 , in some alternative embodiments, when the flexible part 21 is not recessed in the first accommodating area 231, the flexible part 21 and the rigid part 22 are arranged in the horizontal direction, and the first opening 224 can be arranged to extend in the vertical direction. Or, the flexible part 21 and the rigid part 22 are arranged in the vertical direction. Or, the first opening 224 can also be inclined.

[0091] Optionally, when the flexible part 21 is not recessed in the first accommodating area 231, the first opening 224 is located above the flexible part 21.

[0092] For example, the first opening 224 can be arranged to extend in the horizontal direction, and the rigid part 22 can be located directly above the flexible part 21. Specifically, when the flexible part 21 is not recessed in the first accommodating area 231, the first opening 224 is located above the flexible part 21, and the flexible part 21 is located below the rigid part 22. Even when the liquid in the first chamber 23 is less, the liquid acts on the flexible part 21 preferentially. The flexible part 21 sags under its own gravity or under the action of the contained liquid and moves away from the first accommodating area 231, reducing the interference with the first accommodating area 231, which is convenient for the installation of the functional mechanism and also helps to further reduce the risk of interference between the flexible part 21 and the functional mechanism.

[0093] Or, the first opening 224 can be inclined, and the rigid part 22 can be located above the side of the flexible part 21. When the first opening 224 is inclined, the flexible part 21 has a side wall extending in the vertical direction and a bottom wall extending in the horizontal direction, so that the flexible part 21 will generate deformation when being squeezed by fluids in both the horizontal and vertical directions, improving the flexibility of the flexible part 21 to generate deformation, and thus more effectively changing the volume ratio of the first chamber 23 and the second chamber 11. In addition, the inclined arrangement of the first opening 224 enables the first opening 224 to be located on one side of the flexible part 21 in the circumferential direction, so that at least one side of the flexible part 21 will not be squeezed in the horizontal direction, and it can also effectively prevent the four sides of the flexible part from being squeezed in the horizontal direction and moving closer to the middle to block the liquid flow path.

[0094] Optionally, when the soft part 21 is not deformed by depression and is in its natural initial state, the first chamber 23 formed by the hard part 22 and the soft part 21 can be in the shape of a cuboid, and the second box body 2 can also be in the shape of a cuboid. However, it can be understood that the shapes of the first chamber 23 and the second box body 2 are not limited to the cuboid shape and can also be other shapes.

[0095] It can be understood that in this application, the orientation definitions such as up, down, horizontal direction, and vertical direction are based on the orientation of the water tank in the normal operating state of the cleaning device; among them, the vertical direction includes the Z direction in the drawings, and the horizontal direction includes the X direction and the Y direction in the drawings.

[0096] See Figures 5 to 7 , in some alternative embodiments, a recessed avoidance area 223 is provided on the side wall at the upper end of the hard part 22. The installation part includes the avoidance area 223, and the avoidance area 223 is located above the soft part 21. As a part of the installation part, the avoidance area 223 can be used to install the functional mechanism, further saving space and making the structure compact.

[0097] See Figures 1 to 5 , in some alternative embodiments, the functional mechanism includes a sewage suction channel 5. At least part of the sewage suction channel 5 is formed between the avoidance area 223 and the inner wall of the first box body 1, and / or the avoidance area 223 is for installing at least part of the sewage suction channel 5; one end of the sewage suction channel 5 is communicated with the outside of the water tank, and the other end is connected to a negative pressure pumping device 41. The negative pressure pumping device 41 is adapted to pump the sewage suction channel 5 into a negative pressure to suck the dirty liquid into the chamber for containing the dirty liquid through the sewage suction channel 5. Part of the sewage suction channel 5 is formed in the avoidance area 223 or installed in the avoidance area 223, making the structure more compact. The negative pressure pumping device 41 can be, for example, a blower, etc., and is not limited.

[0098] See Figures 1 to 5 , in some alternative embodiments, the first chamber 23 is used to contain the cleaning liquid, and the second chamber 11 is used to contain the dirty liquid, making the setting of the sewage suction channel 5 simpler and more convenient, without the need to set up many openings and sealing structures. Specifically, when the first chamber 23 contains the cleaning liquid and the second chamber 11 contains the dirty liquid, a recessed avoidance area 223 is provided on the side wall at the upper end of the hard part 22. At least part of the sewage suction channel 5 is formed between the avoidance area 223 and the inner wall of the first box body 1. With the above structure, the setting of the sewage suction channel 5 is made simpler and more convenient, without the need to set up many openings and sealing structures; and it can also effectively avoid the interference of the deformation of the soft part 21 on the sewage suction channel 5 while making the water tank structure more compact.

[0099] See Figure 5 , Figure 6 , Figure 10 andFigure 11 , in some alternative embodiments, it further includes a gas-liquid separation device 42 disposed in the avoidance area 223. The gas-liquid separation device 42 includes a housing 421 having a liquid inlet 4211, a gas outlet 4212, and a liquid drain 4213. The liquid inlet 4211 is communicated with the sewage suction channel 5; the liquid drain 4213 is communicated with a chamber for accommodating dirty liquid, the gas outlet 4212 is communicated with the air inlet of the negative pressure pumping device 41, and the liquid drain 4213 is lower than the gas outlet 4212. The gas-liquid separation device 42 is disposed in the avoidance area 223, which more effectively avoids the deformation of the soft part 21 from affecting the fluid channels of the gas-liquid separation device 42.

[0100] See Figure 5 , Figure 6 , Figure 10 and Figure 11 , in some alternative embodiments, the gas-liquid separation device 42 includes at least one baffle member 43 disposed in the housing 421. Among them, the baffle member 43 may include a plurality of baffle plates, and the baffle plates include straight plates and / or bent plates having an arc structure. The baffle plates can be arranged at different positions in the housing 421 according to requirements, so that the liquid velocity in the gas-liquid mixture is less than the gas velocity. After the gas flow containing liquid hits the baffle plate and turns sharply, due to the different inertia of gas and liquid, the gas flow is more likely to change its direction and continue to flow downstream, while the small liquid droplets will hit the baffle plate and converge. The liquid has a greater mass than the gas, and generally deposits below after convergence, so that the liquid in the gas-liquid mixture will be deposited successively during the transportation process. It is also possible to set the liquid drain 4213 lower than the gas outlet 4212, so that the liquid can be discharged into the chamber for containing dirty liquid through the liquid drain 4213 based on gravity. When the gas-liquid mixture reaches near the air inlet of the negative pressure pumping device 41, there is basically no liquid or only a small amount of liquid, reducing the impact on the outside air or the internal components of the cleaning device. Of course, a simple gas-liquid separation mechanism can also be configured in the negative pressure pumping device 41 to further perform gas-liquid separation and reduce the impact on the outside air or the internal components of the cleaning device.

[0101] Optionally, when the baffle member 43 is a baffle plate with an arc-shaped structure, the baffle member 43 has at least one arc-shaped surface 431. The arc-shaped surface 431 is recessed from the side of the liquid inlet 4211 towards the side of the gas outlet 4212. The fluid in the dirt suction channel 5 sequentially passes through the liquid inlet 4211 and the arc-shaped surface 431, and then the liquid in the fluid is discharged through the liquid outlet 4213, and the gas in the fluid is discharged through the gas outlet 4212. The baffle member 43 adopts an arc-shaped baffle plate recessed towards the gas outlet 4212, which can make the flow direction of the fluid change more gently without splashing. At the same time, by using the arc-shaped baffle plate recessed towards the gas outlet 4212, the fluid can be more concentrated after turning, and then the liquid is easier to converge and deposit. At the same time, in the case of arranging multiple baffle plates on the fluid path, by using the arc-shaped baffle plate recessed towards the gas outlet 4212, it is also possible to avoid excessive deceleration of the gas-liquid mixture at the beginning, which affects the flow effect of the gas-liquid mixture.

[0102] Optionally, the number of the liquid outlets 4213 can be one or more. Baffle plates corresponding to each liquid outlet 4213 are provided in the housing 421, and baffle plates can be provided at positions corresponding to the liquid outlets 4213 in the housing 421. The gas-liquid separation effect is good, and the separated liquid can be discharged in time.

[0103] See Figure 5 、 Figure 6 、 Figure 10 and Figure 11 , in some alternative embodiments, the liquid outlet 4213 is located below the arc-shaped surface, and the gas outlet 4212 is located above the arc-shaped surface. By arranging the liquid outlet 4213 below the arc-shaped surface and the gas outlet 4212 above the arc-shaped surface, the liquid has a greater mass than the gas, and the convergence will generally deposit below, which can prevent the negative pressure generated by the negative pressure pumping device 41 from bringing the liquid into the gas outlet. At the same time, it is also convenient for the converged liquid to directly fall into the chamber for containing dirty liquid by gravity, improving the gas-liquid separation effect.

[0104] Baffle plates can be arranged on the fluid flow path. See Figure 5 、 Figure 6 、 Figure 10 and Figure 11, in some alternative embodiments, the baffle member 43 includes at least one first baffle plate. The liquid discharge port 4213 and the gas outlet 4212 are located on one side of the first baffle plate, and the liquid inlet 4211 is located on the other side of the first baffle plate. One end of the first baffle plate is fixed to the housing 421, and a communication port is formed between the other end and the side wall of the housing 421, so that the cavities on both sides of the first baffle plate in the housing 421 are communicated. Arranging at least one first baffle plate in the fluid flow path in the housing 421 is conducive to converging the liquid in advance and further improving the gas-liquid separation effect. At the same time, one end of the first baffle plate is fixed to the housing of the gas-liquid separation device, and a communication port is formed between the other end and the side wall of the housing of the gas-liquid separation device, and the side wall of the housing of the gas-liquid separation device can also be used to change the flow direction of the fluid, reduce the number of baffle members provided, and reduce the structural complexity.

[0105] See Figure 5 , Figure 6 , Figure 10 and Figure 11 , in some alternative embodiments, the baffle member 43 includes a second baffle plate. The gas outlet 4212 is provided on the side wall of the housing 421, the liquid discharge port 4213 is provided on the bottom wall of the housing 421, and the arc surface of the second baffle plate is provided on the inner wall surface of the side wall where the gas outlet 4212 is located. Arranging a baffle plate at a position directly below the gas outlet 4212 in the housing 421 is conducive to further reducing the liquid entering the gas outlet 4212.

[0106] See Figure 5 , Figure 6 , Figure 10 and Figure 11 , in some alternative embodiments, a guiding portion is provided at one end of the first baffle plate close to the communication port, and the guiding portion is bent towards the arc surface of the rear first baffle plate or the second baffle plate located on the gas flow path. In the case where there are multiple first baffle plates, in the fluid flow path, the guiding portion of the front first baffle plate can be bent towards the arc surface of the rear first baffle plate located on the gas flow path; the guiding portion of the last first baffle plate can be bent towards the arc surface of the second baffle plate to guide the fluid to flow in the direction of the rear baffle plate on the gas flow path, ensuring that each baffle plate can effectively achieve the gas-liquid separation effect.

[0107] See Figure 3 , Figures 5 to 7, in some alternative embodiments, an overflow port 24 communicating the first chamber 23 and the second chamber 11 is provided on the rigid part 22, and the overflow port 24 is located on the fluid flow path of the sewage suction channel 5. Among them, the overflow port 24 is located on the fluid flow path within the housing 421, which is beneficial for the air flow overflowing from the overflow port 24 to flow along the gas flow of the fluid flow path and be discharged out of the water tank from the air inlet of the negative pressure pumping device 4. The air pressure environment of the fluid flow path within the housing 421 can also assist in accelerating the flow rate of the air flow overflowing from the overflow port 24.

[0108] See Figures 3 to 6 , in some alternative embodiments, an overflow port 24 communicating the first chamber 23 and the second chamber 11 is provided at the upper part of the second box body 2.

[0109] Optionally, the overflow port 24 is located at the upper part of the side wall of the rigid part 22, which can not only avoid the interference of the soft part 21, but also does not need to close the overflow port 24 when the water tank performs the operation of sucking sewage to form negative pressure, simplifying the structure and making the operation more simple. Specifically, when the water tank performs the operation of sucking sewage, a negative pressure environment will be formed, and the air flow in the chamber filled with the cleaning liquid can be directly discharged into the chamber filled with the dirty liquid through the overflow port 24 and sucked away by the negative pressure, without the need to additionally set a separate exhaust valve; even if the liquid in the chamber filled with the cleaning liquid overflows due to air pressure, the water will directly overflow into the chamber filled with the dirty liquid and will not enter other spaces to damage the equipment.

[0110] For the water tank of the above embodiments, an overflow port 24 communicating the first chamber 23 and the second chamber 11 is provided at the upper part of the second box body 2, so that one of the first chamber 23 and the second chamber 11 can receive the water overflowing from the other. For example, when the water in the first chamber 23 is the cleaning liquid, the cleaning liquid in the first chamber 23 can directly overflow into the second chamber 11 through the overflow port 24; in addition, the overflow port 24 can also make the air pressures of the first chamber 23 and the second chamber 11 consistent, so that the soft part 21 can move normally to deform.

[0111] See Figures 3 to 7, in some alternative embodiments, a second liquid level monitoring member adapted to monitor a preset maximum liquid level in the second chamber 11 is installed in the second chamber 11. The preset maximum liquid level monitored by the second liquid level monitoring member is lower than the liquid discharge port 4213, the liquid discharge port 4213 is lower than the gas outlet 4212, and the liquid discharge port 4213 is lower than the overflow port 24. When the second liquid level monitoring member monitors that the water in the second chamber 11 exceeds the preset maximum liquid level, the negative pressure pumping device 41 is turned off, the second chamber 11 is no longer pumped with negative pressure, the dirty liquid in the second chamber 11 no longer increases, an alarm is given to remind, and the dirty liquid in the second chamber 11 is discharged, thereby preventing the dirty liquid in the second chamber 11 from flowing back through the liquid discharge port 4213 and entering the first chamber, the sewage suction channel, the gas-liquid separation device 42, and the negative pressure pumping device 41, which is beneficial to preventing damage to the negative pressure pumping device 41 and other circuits in the device.

[0112] See Figure 1 , Figure 5 , Figure 12 and Figure 13 , in some alternative embodiments, the number of the sewage suction channels 5 can also be set according to requirements, for example, it can be one, two, or more.

[0113] See Figures 3 to 7 , in some alternative embodiments, the sewage suction channel 5 includes a first section 51 and a second section 52 connected to the first section 51. The second section 52 is formed by enclosing the space between the avoidance area 223 and the inner wall of the first box body 1, and / or the avoidance area 223 is provided for installing the second section 52. The second section 52 is connected to the negative pressure pumping device 41, and the first section 51 communicates with the outside of the water tank. Among them, the second section 52 is formed by enclosing the space between the avoidance area 223 and the inner wall of the first box body 1, which can not only simplify the structure but also reduce the influence of the air pressure in the second section 52 on the deformation of the soft part 21; the avoidance area 223 is provided for installing the second section 52 to avoid interference between the second section 52 and the soft part 21.

[0114] See Figures 3 to 7 , in some alternative embodiments, the first section 51 is formed on the outer side wall of the first box body 1, which can reduce the occupation of the internal space of the first box body 1 and save space; or, the first section 51 is defined by enclosing a part of the outer side wall of the hard part 22 and a part of the inner side wall of the first box body 1, which not only has a simple and compact structure but also avoids interference of the soft part 21 on the first section 51.

[0115] In addition, the first section 51 can be arranged at the corner position of the first box body 1, the middle of the side wall of the first box body 1, or other positions.

[0116] Optionally, the first box body 1 can be in the shape of a cuboid. In the length direction of the first box body 1, the first section 51 is located in the middle of one side of the first box body 1, and the first section 51 is located in the middle of the side wall of the first box body 1. In this application, the length direction of the first box body 1 can be the X direction in the drawings, the width direction of the first box body 1 can be the Y direction in the drawings, and the height direction of the first box body 1 can be the Z direction in the drawings.

[0117] For the water tank in the above embodiment, the first section 51 can be flexibly arranged according to requirements. In particular, the first section 51 is arranged in the middle of the side wall of the first box body 1, so that the first section 51 is located at a relatively central position in the first box body 1, which is beneficial to shortening the conveying path. The first section 51 is convenient to set and is conducive to being processed into a straight pipe structure.

[0118] See Figure 1 、 Figure 5 、 Figure 12 and Figure 13 , in some alternative embodiments, the first section 51 extends vertically in a straight pipe structure. The first section 51 adopting a straight pipe structure can reduce the risk of blockage of the first section 51, facilitate dredging and maintenance, reduce the loss of air volume and reduce noise.

[0119] Optionally, the first section 51 can adopt a top water spraying method or a side water spraying method. Among them, the first section 51 has a lower end inlet 511 and an upper end outlet 512. When adopting the side water spraying method, a turning joint can be connected at the upper end outlet 512, which is beneficial to adapting to various installation environments and reducing the requirements for the installation environment.

[0120] See Figures 3 to 7 , in some alternative embodiments, the gas-liquid separation device 42 is arranged in the second section 52, and the liquid discharge port 4213 is arranged on the bottom wall of the second section 52. The second section 52 extends horizontally, which is beneficial to separating the gas and liquid in the fluid and enabling the liquid to be discharged from the liquid discharge port 4213 in time. The gas is drawn away and discharged from the air inlet of the negative pressure pumping device 41, reducing the influence of air pressure on the deformation of the soft part 21.

[0121] Optionally, the liquid discharge ports 4213 can be distributed at different positions on the bottom wall of the second section 52 according to requirements, so that the sewage can fall into the second chamber 11 in time under the action of its own gravity after sedimentation.

[0122] See Figures 3 to 7, in some alternative embodiments, the upper end outlet 512 of the first section 51 connected to the second section 52 is lower than the liquid discharge port 4213. Generally, when the second liquid level monitoring member monitors that the liquid level in the second chamber 11 reaches the preset maximum liquid level, the controller will control the negative pressure pumping device 41 to close, and no more dirty liquid will be sucked into the second chamber 11. However, there may be a special situation where the water in the second chamber 11 continues to rise when the second liquid level monitoring member monitors that the liquid level reaches the preset maximum liquid level. For example, the cleaning liquid in the first chamber 23 overflows from the overflow port 24, resulting in the liquid level in the second chamber 11 still rising after reaching the preset maximum liquid level, which easily causes the water in the second chamber 11 to rise and backflow from the liquid discharge port 4213. By setting the position of the upper end outlet 512 of the first section 51 lower than the liquid discharge port 4213, the backflow liquid can flow back to the ground from the upper end outlet 512 of the first section 51, so that in extreme cases, the liquid in the second chamber 11 can be prevented from flowing into the negative pressure pumping device 41 and damaging the equipment.

[0123] Optionally, the detection principle and detection structure of the second liquid level monitoring member are not limited. The second liquid level monitoring member can be a float type liquid level sensor, a float drum type liquid level sensor, etc.

[0124] See Figures 3 to 7 , in some alternative embodiments, the gas-liquid separation device 42 can be embedded between the outer side wall of the rigid part 22 and the inner side wall of the first water tank.

[0125] See Figure 1 , Figure 3 , Figure 5 , Figure 12 and Figure 13 , in some alternative embodiments, the water tank is installed in the cleaning device, and the cleaning device further includes a cleaning component 81, a dirt suction port, and a sewage discharge port 82. The dirt suction port is used to suck the dirty liquid on the cleaning component or the dirty liquid on the working surface cleaned by the cleaning component; the sewage discharge port 82 communicates with the dirt suction port and the dirt suction channel 5 to suck the dirty liquid into the second chamber 11; the dirt suction ports are arranged along the preset direction of the cleaning component with the sewage discharge port 82 as the center, and the first section 51 extends vertically and is formed with a lower end inlet 511 communicating with the sewage discharge port 82.

[0126] Optionally, the cleaning component 81 includes a sewage collection component of the host, a wet cleaning part, or a cleaning tray of the base station. A plurality of sewage suction ports are evenly arranged on the cleaning component 81, and the dirty liquid enters through the plurality of sewage suction ports and is concentrated through the sewage discharge port 82 to enter the first section 51 from the lower end inlet 511 of the first section 51; wherein, the plurality of sewage suction ports are evenly arranged at the bottom of the cleaning component 81. Further, the cleaning component 81 can be in a long strip shape or an arc shape. The cleaning component 81 designed in this structure is beneficial to increasing the sewage suction area. It can be understood that the shape of the cleaning component 81 is not limited to the shapes exemplified above, and can also be designed into other shapes according to requirements.

[0127] For the water tank of the above embodiment, the sewage suction ports are evenly arranged on the cleaning component 81 and are arranged along the preset direction of the cleaning component 81 with the sewage discharge port 81 as the center, which is beneficial to evenly distributing the suction force to each sewage suction port through the sewage discharge port 82, making the air pressure of each sewage suction port the same, facilitating uniform sewage suction, reducing air volume loss, improving sewage suction efficiency, enabling a smaller number of the first sections 51 to also ensure the sewage suction effect, and being beneficial to simplifying the structure and reducing costs.

[0128] See Figures 3 to 5 、 Figures 8 to 12 In some alternative embodiments, the functional mechanism of the first chamber 23 includes a valve 33 and / or a delivery pipeline assembly 31 and / or a first liquid level monitoring member 32. The valve 33 is adapted to open unidirectionally to communicate the first chamber 23 and the second chamber 11, so that the cleaning liquid flows to the chamber for accommodating the dirty liquid; the delivery pipeline assembly 31 is used for communicating the first chamber 23 with the outside of the water tank; the first liquid level monitoring member 32 is used for monitoring the liquid level in the first chamber 23.

[0129] See Figure 5 、 Figures 8 to 12 In some alternative embodiments, the top wall of the hardware part 22 is further provided with a third opening 221 communicating with the first chamber 23. The third opening 221 includes a placement space for accommodating the fixed platform 222 and a reserved operation space; the fixed platform 222 is installed on the installation part, and the fixed platform 222 is for installing the functional mechanism of the first chamber 23. The operation space can be a space for operating the functional mechanism of the first chamber 23, such as disassembling, assembling, and maintaining the functional mechanism of the first chamber 23; the operation space can also be a space for adding liquid to the first chamber 23. It is not only simple and convenient to install and operate, but also has a compact structure layout, which is beneficial to reducing the occupied space.

[0130] See Figure 5 、 Figures 8 to 12In some optional embodiments, part of the fixed platform 222 is formed as a water and electricity compartment 225, and a transfer component suitable for external connection of at least part of the functional mechanism is sealed and installed in the water and electricity compartment 225. The water and electricity compartment 225 can be sealed by a sealing cover. The transfer component can be used to provide a transfer interface for external connection of the conveying pipeline assembly 31 and / or the circuit for powering the first liquid level monitoring component 32 and / or the circuit for powering the valve 33 and / or other components, thereby realizing the transfer of the functional mechanism and the components located outside the water tank.

[0131] In the water tank of the above embodiment, part of the fixed platform 222 is formed into a water and electricity compartment 225, which can not only provide space to realize the connection between the functional mechanism inside the water tank and the components outside the water tank, but also the space of the water and electricity compartment 225 is relatively closed, which can reduce the influence of water vapor on the components installed in the water and electricity compartment 225, especially reduce the influence on components such as circuits, thereby improving safety and reliability.

[0132] See also Figures 3 to 5 , Figures 8 to 12 In some optional embodiments, the functional mechanism of the first chamber 23 includes a delivery pipeline assembly 31, and the first chamber 23 is connected to the outside of the water tank through the delivery pipeline assembly 31. The liquid in the first chamber 23 can be delivered to the outside of the water tank through the delivery pipeline assembly 31.

[0133] Optionally, when cleaning liquid is accumulated in the first chamber 23, the cleaning liquid may be clean water or clean water with added detergent or other liquid with cleaning ability. The delivery pipe assembly 31 is connected to the cleaning assembly 81 outside the water tank, and the cleaning liquid in the first chamber 23 is delivered to the cleaning assembly 81 through the delivery pipe assembly 31, so that the cleaning assembly 81 performs the cleaning operation.

[0134] Optionally, the delivery pipeline assembly 31 includes components such as a water pipe (not shown in the figure) and / or a valve and / or a water inlet and / or a water pump; wherein the water pump provides suction power to transport the water in the first chamber 23 to the outside of the water tank through the water pipe.

[0135] Optionally, some components of the delivery pipeline assembly 31 can be installed on the bottom wall of the hardware part 22, for example, the water inlet end of the delivery pipeline assembly 31 is installed on the bottom wall of the hardware part 22, which is conducive to the full drainage of the liquid in the first chamber 23; some components of the delivery pipeline assembly 31 can be installed on the fixed platform 222, for example, the water outlet end of the delivery pipeline assembly 31 is installed on the fixed platform 222.

[0136] For the water tank of the above embodiment, by installing the conveying pipeline assembly 31 on the installation part of the rigid part 22, not only can a stable and reliable support be provided for the conveying pipeline assembly 31, the installation is simple and convenient, but also the interference of the soft part 21 on the conveying pipeline assembly 31 can be effectively avoided, thus affecting the normal operation of the conveying pipeline assembly 31, and the reliability of the conveying pipeline assembly 31 can be improved.

[0137] See Figure 4 、 Figure 5 、 Figures 8 to 11 , in some alternative embodiments, the functional mechanism of the first chamber 23 includes a valve 33 adapted to open unidirectionally to communicate the first chamber 23 and the second chamber 11, so that the cleaning liquid flows into the chamber for containing the dirty liquid. The valve 33 adopts a unidirectional opening mode to prevent the dirty liquid from flowing back and contaminating the cleaning liquid.

[0138] Optionally, the valve core 331 of the valve 33 is installed on the bottom wall of the rigid part 22. One end of the valve stem 332 of the valve 33 is movably arranged on the fixed platform 222, the other end of the valve stem 332 is connected to the valve core 331, and the pull ring 333 of the valve 33 is installed at one end of the valve stem 332 and exposed at the third opening 221. By driving the pull ring 333 to move the valve stem 332, the valve core 331 at the bottom of the valve stem 332 is driven to move to open or close the valve 33, and the operation is simple. Further, the valve core 331 can be a plug. A liquid discharge hole is formed on the rigid part 22. The valve stem 332 is connected to the plug and can drive the plug to block and open the liquid discharge hole. It can be understood that the structure of the valve 33 is not limited to the mechanical valve 33 exemplified above, and an electric valve 33 can also be adopted so that the valve 33 can be automatically opened and closed according to instructions.

[0139] For the water tank of the above embodiment, by providing the valve 33 capable of communicating the first chamber 23 and the second chamber 11, cleaning liquid can be introduced into the chamber to be cleaned for cleaning. The water tank can be cleaned without disassembling and assembling parts, especially for cleaning the chamber containing dirty liquid, and the cleaning operation is simple and convenient. In addition, by installing the valve 33 on the installation part of the rigid part 22, not only a stable and reliable support is provided for the valve 33, the installation is simple and convenient, but also the interference of the soft part 21 on the valve 33 can be effectively avoided, thus affecting the normal operation of the valve 33, and the reliability of the valve 33 can be improved.

[0140] See Figure 4 、 Figure 5 、 Figures 8 to 11 , in some alternative embodiments, the functional mechanism of the first chamber 23 includes a first liquid level monitoring member 32, and the first liquid level monitoring member 32 is adapted to monitor the liquid level in the first chamber 23.

[0141] Optionally, the bottom end of the first liquid level monitor 32 is supported and fixed on the bottom wall of the rigid part 22, and the top end of the first liquid level monitor 32 is supported and fixed on the fixed platform 222.

[0142] Optionally, the detection principle and detection structure of the first liquid level monitor 32 are not limited. The first liquid level monitor 32 can be a float type liquid level sensor, a float drum type liquid level sensor, etc.

[0143] For the water tank of the above embodiment, by installing the first liquid level monitor 32 on the installation part of the rigid part 22, the rigid part 22 can not only provide stable and reliable support for the first liquid level monitor 32, with simple and convenient installation, but also effectively avoid the interference of the flexible part 21 on the first liquid level monitor 32 and affect the normal operation of the first liquid level monitor 32, improving the reliability of the first liquid level monitor 32.

[0144] See Figure 1 、 Figure 5 and Figure 6 In some alternative embodiments, the second box body 2 is detachably installed in the first box body 1.

[0145] Optionally, a handle 25 is provided at the top of the second box body 2 to facilitate the taking and placing of the second box body 2. Further, the handle 25 is provided on the top wall of the rigid part 22 and outside the first chamber 23.

[0146] Optionally, the top edge of the second box body 2 has a flanging that bends outward. When the second box body 2 is installed in the first box body 1, the second box body 2 is suspended in the first box body 1 by the limit of the flanging and the top end of the first box body 1. This structural design is not only convenient for disassembly and assembly, but also facilitates the installation of a sealing ring at the assembly position to achieve a sealed fit, avoiding the water vapor in the second chamber 11 from overflowing and affecting other components. It can be understood that the assembly method of the second box body 2 and the first box body 1 is not limited to the above-listed methods, and other assembly methods can also be used to stably install the second box body 2 in the first box body 1.

[0147] For the water tank of the above embodiment, the second box body 2 is detachably installed in the first box body 1. Given the above arrangement of the second box body 2, it is also relatively easy to disassemble and assemble. The second box body 2 can be very conveniently taken out without affecting the various functional components of the water tank, and the first box body 1, the second box body 2 and the functional mechanisms in the water tank can be cleaned, or the functional mechanisms in the water tank can be maintained.

[0148] See Figure 1 and Figure 5, in some alternative embodiments, the water tank further includes a tank cover 12 which is pivotally mounted on the first box body 1. The tank cover 12 can be pivoted open and closed. When the tank cover 12 is opened, the second box body 2 can be taken and placed. When the tank cover 12 is closed, it can cover the top of the second box body 2.

[0149] See Figures 3 to 11 , in some alternative embodiments, the water tank further includes a protective bracket 6 which is installed in the second chamber 11. When the soft part 21 is not recessed in the first accommodating area 231, the protective bracket 6 is used to support the soft part 21; the protective bracket 6 is provided with a through water-permeable hole 61 which communicates the side of the protective bracket 6 facing the soft part 21 and the side facing away from the soft part 21.

[0150] Optionally, the protective bracket 6 can be fixedly connected to the hard part 22 by screws, bonding or other connection means, and the hard part 22 provides installation support for the protective bracket 6; or, the protective bracket 6 can be fixedly connected to the side wall of the first box body 1 by screws, bonding or other connection means, and the first box body 1 provides installation support for the protective bracket 6; or, the protective bracket 6 can be placed and fixed on the bottom wall of the first box body 1 and fixed by screws, bonding or other means.

[0151] For the water tank of the above embodiment, the protective bracket 6 is suitable for supporting the soft part 21, preventing the soft part 21 from shaking during operation, and reducing the excessive deformation of the soft part 21 caused by the large force exerted by the liquid in the first chamber on the soft part 21 when the liquid in the second chamber is less and the liquid in the first chamber is more, or preventing the loosening of the fixation between the soft part and the hard part, thereby increasing the service life of the soft part 21. And the water-permeable hole 61 is suitable for communicating the side of the protective bracket 6 facing the soft part 21 and the side facing away from the soft part 21, so that the liquid in the second chamber 11 can enter the protective bracket 6 from the water-permeable hole 61 to squeeze the soft part 21 to cause the soft part 21 to generate a flexible deformation, thereby reducing the volume space of the first chamber 23 and further increasing the volume space of the second chamber 11.

[0152] See Figures 3 to 11 、 Figure 14 and Figure 15 , in some alternative embodiments, the bottom of the soft part 21 and / or the bottom of the protective bracket 6 are designed with an inclined surface structure, and the position of the inclined surface structure close to the functional mechanism is lower than the position of the inclined surface structure far from the functional mechanism, so as to guide the liquid in the first chamber 23 to flow towards the functional mechanism.

[0153] Optionally, one side of the protective bracket 6 facing the soft part 21 has a first inclined surface 62. The position of the first inclined surface 62 close to the functional mechanism is lower than the position of the first inclined surface 62 away from the functional mechanism. The first inclined surface 62 is adapted to fit with the bottom surface of the soft part 21 to guide the liquid in the first chamber 23 to flow towards the functional mechanism in the first chamber 23. Further, the height where the first inclined surface 62 is located gradually decreases from the position away from the functional mechanism to the position close to the functional mechanism. Specifically, the height where the first inclined surface 62 is located gradually decreases from the water inlet end of the conveying pipeline assembly 31 away from the functional mechanism to the water inlet end of the conveying pipeline assembly 31 close to the functional mechanism, so that the water inlet end of the conveying pipeline assembly 31 is at the lowest position in the second chamber 11, so that the water in the second chamber 11 can be fully discharged.

[0154] Optionally, the conveying pipeline assembly 31, the first liquid level monitoring member 32, and the valve 33 are all arranged on the same side of the hard part 22. The bottom wall of the hard part 22 can be at the lowest position in the second chamber 11, so that the conveying pipeline assembly 31 and the valve 33 can discharge the water in the second chamber 11 to the maximum extent to avoid waste; the first liquid level monitoring member 32 can monitor the lowest liquid level in the second chamber 11.

[0155] When the first chamber is used to accommodate the cleaning liquid and the second chamber is used to accommodate the dirty liquid, the first box body is provided with a sewage outlet communicating the second chamber with the outside of the water tank. The bottom of the second chamber has a second inclined surface. The position of the second inclined surface close to the sewage outlet is lower than the position of the second inclined surface away from the sewage outlet. The second inclined surface is adapted to guide the dirty liquid in the second chamber to flow towards the sewage outlet, so as to completely discharge the dirty liquid.

[0156] In some alternative embodiments, the first box body 1 is further provided with a sewage outlet 13. The sewage outlet 13 communicates the second chamber 11 with the outside of the water tank. The bottom of the second chamber 11 has a second inclined surface 14. The position of the second inclined surface 14 close to the sewage outlet 13 is lower than the position of the second inclined surface 14 away from the sewage outlet 13. The second inclined surface 14 is adapted to guide the dirty liquid in the second chamber 11 to flow towards the sewage outlet 13, which is beneficial to discharging the dirty liquid in the second chamber 11. The height where the second inclined surface 14 is located gradually decreases from the position away from the sewage outlet 13 to the position close to the sewage outlet 13. This structural design is beneficial to fully discharging the dirty liquid in the second chamber 11.

[0157] See Figure 14 and Figure 15, in some alternative embodiments, the water tank includes a first box body 1, a separating member 7 and a protective bracket 6. The first box body 1 has a liquid storage cavity. The separating member 7 is installed in the first box body 1. The separating member 7 has a soft part 21. The soft part 21 divides the liquid storage cavity into a first chamber 23 and a second chamber 11 with relatively variable volume ratios. One of the first chamber 23 and the second chamber 11 is used to hold the cleaning liquid, and the other is used to hold the dirty liquid; the protective bracket 6 is installed in the first box body 1. The protective bracket 6 is located on one side of the soft part 21 facing away from the concave direction of the soft part 21 and supports the soft part 21; the protective bracket 6 is provided with a through water-permeable hole 61, and the water-permeable hole 61 communicates with one side of the protective bracket 6 facing the soft part 21 and the side facing away from the soft part 21.

[0158] For the water tank of the above embodiment, the separating member 7 has a soft part 21, so that the volumes of the first chamber 23 and the second chamber 11 can change relatively, reducing space waste and facilitating the production of the water tank in a smaller volume. In addition, a protective bracket 6 suitable for supporting the soft part 21 is provided to prevent the soft part 21 from shaking during operation, and to reduce the excessive deformation of the soft part 21 caused by the large force exerted on the soft part 21 by the liquid in the first chamber when the liquid in the second chamber is less and the liquid in the first chamber is more, or to prevent the fixing between the soft part and the hard part from loosening, thereby increasing the service life of the soft part 21. The water-permeable hole 61 is suitable for communicating the side of the protective bracket 6 facing the soft part 21 and the side facing away from the soft part 21, so that the liquid in the second chamber 11 can enter the protective bracket 6 from the water-permeable hole 61 to squeeze the soft part 21 to cause the soft part 21 to generate a flexible deformation, thereby reducing the volume space of the first chamber 23 and further increasing the volume space of the second chamber 11.

[0159] See Figure 14 and Figure 15 , in some alternative embodiments, the separating member 7 is detachably installed in the first box body 1.

[0160] Optionally, the separating member 7 is provided with a handle 25 for easy taking and placing.

The first chamber 23 and the second chamber 11 are adapted to communicate when the valve 33 is open, so that the clean liquid can flow into the chamber containing the dirty liquid. By providing the valve 33 that can connect the first chamber 23 and the second chamber 11, clean liquid can be introduced into the chamber to be cleaned for cleaning, and the water tank can be cleaned without disassembling and assembling parts, especially for the chamber containing dirty liquid, and the cleaning operation is simple and convenient.

[0163] See Figure 14 , in an alternative embodiment, the first chamber 23 and the second chamber 11 are distributed horizontally.

[0164] See Figure 14 , in an alternative embodiment, the first chamber 23 and the second chamber 11 are distributed vertically.

[0165] Optionally, the first chamber 23 is located above the second chamber 11, or the first chamber 23 is located below the second chamber 11. Further, when the first chamber 23 is located above the second chamber 11, the first chamber 23 is used to contain clean liquid, and the second chamber 11 is used to contain dirty liquid.

[0166] See Figure 14 and Figure 15 , in some alternative embodiments, an overflow port 24 adapted to connect the first chamber 23 and the second chamber 11 is provided at the upper part of the isolation member 7. The overflow port 24 that connects the first chamber 23 and the second chamber 11 is provided on the isolation member 7, so that one of the first chamber 23 and the second chamber 11 can receive the liquid overflowing from the other. For example, when the water in the first chamber 23 is clean liquid, the clean liquid in the first chamber 23 can directly overflow into the second chamber 11 through the overflow port 24; in addition, the overflow port 24 can also make the air pressures in the first chamber 23 and the second chamber 11 consistent, so that the soft part 21 can move and deform normally.

[0167] See Figure 1 and Figure 5 、 Figure 14 and Figure 15 , in some alternative embodiments, the water tank further includes a tank cover 12, which is flip-mounted on the first box body 1. The tank cover 12 can be flipped open and closed. When the tank cover 12 is open, the second box body 2 can be taken and placed. When the tank cover 12 is closed, it can cover the top of the second box body 2.

[0168] See Figures 3 to 11 、 Figure 14 and Figure 15, in some alternative embodiments, the part of the flexible part 21 in contact with the protective bracket 6 has an interference amount, and the part of the flexible part 21 placed on the protective bracket 6 has redundancy, ensuring that the flexible part 21 can be in full contact with the protective bracket 6, avoiding the failure of the flexible part 21 caused by shaking or dropping of the flexible part 21, which is beneficial to extending the service life of the flexible part 21 and ensuring the performance of the flexible part 21.
