The present invention provides a cleaning device including, but not limited to, a power mop and a floor scrubbing robot. As shown in fig. 1 and 4, the cleaning apparatus of the present embodiment includes a water tank 100, and the water tank 100 includes a tank 10 and a partition 20. The box 10 in this embodiment is a square column and is vertically disposed, the partition 20 is disposed inside the box 10, and the partition 20 divides the inside of the box 10 into a first cavity 111 and a second cavity 112 which are disposed vertically and are not communicated with each other. The first cavity 111 is used for collecting sewage, and the second cavity 112 is used for storing clean water. The lateral wall position that is close to the top of first cavity 111 is equipped with first through-hole (be equipped with first subassembly of intaking in the first through-hole in the drawing, therefore do not mark), and the lateral wall position that is close to the bottom of second cavity 112 is equipped with the second through-hole (be equipped with the second subassembly of intaking in the second through-hole in the drawing, therefore do not mark), and baffle 20 can be followed the axial direction motion of box 10 under the effect of hydraulic pressure in first cavity 111 to adjust the volume of first cavity 111 and second cavity 112.

According to the water tank 100 of the present invention, the inside of the tank body 10 is divided into the first cavity 111 and the second cavity 112 which are arranged up and down and are not communicated with each other by the partition plate 20, wherein the first cavity 111 above the tank body 10 is used as a sewage cavity for collecting sewage, the second cavity 112 below the tank body 10 is used as a clean water cavity for supplying clean water, the clean water is injected into the second cavity 112, and simultaneously the partition plate 20 moves upwards along the axial direction of the tank body 10 until the partition plate is close to the top surface of the first cavity 111, so as to increase the volume of the second cavity 112, so that the clean water of the tank body 10 gradually fills the volume of the tank body 10, thereby effectively ensuring the supply of clean water. Meanwhile, the clean water in the second cavity 112 is discharged through the second through hole for clean water supply, along with the gradual reduction of the clean water amount in the second cavity 112, the partition plate 20 gradually moves towards the bottom of the second cavity 112, so that the volume of the second cavity 112 is reduced, the volume of the first cavity 111 is increased, the first cavity 111 reflows the generated sewage into the first cavity through the first through hole, and as the sum of the volumes of the first cavity 111 and the second cavity 112 is not changed, the sum of the clean water amount in the second cavity 112 and the generated sewage amount is not changed or is reduced, the first cavity 111 can ensure that the generated sewage is completely collected into the first cavity 111, so that the storage amount of the clean water in the second cavity 112 is effectively increased under the condition that the whole volume of the water tank 100 is not changed, the supply amount of the clean water and the satisfactory effective collection of the sewage are ensured, and the client degree is increased.

In this embodiment, when the clean water is introduced into the second cavity 112, the partition 20 is prevented from completely adhering to the top of the box 10, so that a certain gap is left between the partition 20 and the top of the box 10, thereby effectively collecting the sewage which is not converted from the clean water in the second cavity 112.

Referring to fig. 1 to 4, the case 10 of the present embodiment includes a main body 11, a first cover 12, and a second cover 13. The body 11 includes a first opening end 113 and a second opening end 114, which are oppositely disposed, the first opening end 113 is disposed at the upper end of the body 11, and the second opening end 114 is disposed at the lower end of the body 11. The first cover 12 is detachably connected to the first open end 113, so that a first cavity 111 is formed between the first cover 12 and the partition 20. The second cover plate 13 is removably attached to the second open end 114 such that a second cavity 112 is formed between the second cover plate 13 and the baffle plate 20. In this embodiment, the first through hole is formed at a position close to the first cover plate 12 on the inner wall of the body 11, so that the sewage is conveniently collected into the first cavity 111, and the sewage is prevented from flowing back to the outside of the tank 10. The second through hole is arranged on the inner wall of the body 11 and close to the second cover plate 13, so that the clean water can be conveniently supplied, the clean water in the second cavity 112 can be completely discharged as far as possible, and the supply amount of the clean water can be ensured. In other embodiments of the present application, the first through hole may be disposed on the first cover 12, and the second through hole may be disposed on the second cover 13, which can also achieve the above-mentioned object.

Because in this embodiment, the first cover plate 12 and the second cover plate 13 can be detachably connected to the body, clear water can be quickly injected into the second cavity 112 by detaching the second cover plate 13, and the interior of the first cavity 111 can be cleaned by detaching the first cover plate 12. In other embodiments of the present application, if the first cover plate 12 and the second cover plate 13 at the two ends of the body 11 cannot be detached, the first through hole and the second through hole can be used to introduce clean water into the first cavity 111 and the second cavity 112, respectively, so as to achieve the purpose of storing clean water into the second cavity 112 or cleaning the first cavity 111.

In this embodiment, to facilitate the detachment and assembly between the first cover 12 and the body 11, one end of the first cover 12 is pivotally connected to the body 11, and the other end of the first cover 12 is connected to the body 11 in a snap-fit manner. As shown in fig. 5 to 7, a first connecting end 115 and a second connecting end 116 are respectively disposed on the top of two opposite outer sidewalls of the body 11 in a protruding manner, a first protruding end 121 and a second protruding end 122 are disposed on the first cover plate 12 and extend toward the body 11 along the axial direction of the body 11, and the second protruding end 122 is inserted into the second connecting end 116 and is connected to the second protruding end 122 and the second connecting end 116 by a pin, so as to ensure that the first cover plate 12 can rotate around the pin. The inner side surface of the first protruding end 121 is recessed to form a mounting groove, and the first connection end 115 can be inserted into the mounting groove of the first protruding end 121 and is clamped with the first protruding end 121 through interference fit, so that the first cover plate 12 is fixed above the body 11. When the first cover plate 12 needs to be opened, the first connection end 115 is extended from the mounting groove of the first extension end 121 by rotating the first cover plate 12. In this embodiment, the second cover plate 23 has the same structure as the first cover plate 12, the bottom of two opposite outer side walls of the body 11 are also respectively provided with a first connecting end 115 and a second connecting end 116, and the connecting mode of the second cover plate 13 and the body 11 is the same as that of the first cover plate 12 and the body 11, which is not described herein again.

As shown in fig. 4 and 5, in the present embodiment, a plurality of sliding grooves 117 are disposed in the body 11 along the axial direction of the body 11, a plurality of protrusions 21 adapted to the plurality of sliding grooves 117 are disposed on the partition plate 20, and the plurality of protrusions 21 are respectively disposed in the plurality of sliding grooves 117 in a one-to-one correspondence manner. However, in order to ensure the smooth movement of the boss 21 in the slide groove 117, the inner wall surface of the slide groove 117 in the present embodiment is an arc surface, and the mating surface of the boss 21 with the slide groove 117 is an arc surface as well. In order to facilitate the arrangement of the sliding groove 117 and the partition board 20, the sliding groove 117 is disposed at the corner connection position of the four inner wall surfaces of the body 11 in the present embodiment, and the protrusions 21 on the partition board 20 are also disposed at the corner connection position of the partition board 20.

In this embodiment, in order to ensure that the partition plate 20 does not generate a gap with the inner wall surface of the body 11 during the movement along the axial direction of the body 11, and the sewage in the first cavity 111 pollutes the clean water in the second cavity 112, the outer surface of the partition plate 20 in this embodiment is wrapped with an elastic sealing member. The specific baffle 20 in this embodiment is a hard plastic-coated structure, the baffle 20 is made of hard plastic, and the surface of the baffle 20 is coated with hard rubber, so as to ensure that the center of the baffle 20 has a certain strength and is not easy to deform, and meanwhile, the rubber on the surface of the baffle 20 is completely sealed under the extrusion of the inner wall surfaces of the baffle 20 and the box body 10, so that the first cavity 111 and the second cavity 112 are effectively ensured to be not communicated with each other in the moving process of the baffle 20. In other embodiments of the present application, the elastic sealing element may be attached to the peripheral inner wall of the body 11, and the partition plate 20 presses the elastic sealing element on the inner wall of the body 11 during the moving process, so as to effectively separate the first cavity 111 from the second cavity 112.

As shown in fig. 6 and 7, in the present embodiment, the first cover 12 is provided with a vent hole 123 penetrating the first cover 12. The vent hole 123 is extremely small in size, does not cause liquid loss, and is only used for communicating the external atmosphere with the first cavity 111 to keep the air pressure stable. The structure of the vent 123 is somewhat enlarged in the drawing to show it. The vent 123 is provided to keep the air pressure in the tank 10 stable, and to prevent the first chamber 111 from sucking a large amount of external sewage (sewage converted from clean water supplied from the tank 100) and the clean water in the first chamber 111 is not discharged yet to press the tank 10. Another aspect is to keep the negative pressure suction force of the first chamber 111 to the diaphragm 20 stable. The second cover plate 13 is provided with no vent structure.

Referring to fig. 2 and 3, a pull ring 22 is provided at the bottom of the partition board 20 in the present embodiment, and the second cover plate 13 can be conveniently taken out after being opened by the pull ring 22. In other embodiments of the present application, the pull ring 22 may also be placed on top of the separator 20 to facilitate removal of the separator 20 after the first cover panel 12 is opened.

As shown in fig. 2 and 3, the water tank 100 of the present embodiment further includes a first water inlet assembly 31 and a second water inlet assembly 32, the first water inlet assembly 31 and the second water inlet assembly 32 are respectively inserted into the first through hole and the second through hole, and the first water inlet assembly 31 and the second water inlet assembly 32 are only capable of supplying water to the inside of the tank 10 in one direction.

As shown in fig. 8 and 9, the first water inlet unit 31 of the present embodiment includes a first mounting portion 311, a second mounting portion 312, a valve body 313, a spring 314, and a connecting portion 315. The connection portion 315 is a plate-shaped member disposed on an outer side surface of the first mounting portion 311, and the connection portion 315 is provided with a mounting hole so as to couple and fix the first water inlet assembly 31 to a side wall of the body 11. The second mounting portion 312 is sleeved outside the first mounting portion 311, the valve core 313 is arranged in a mounting cavity formed by the first mounting portion 311 and the second mounting portion 312, a spring 314 is arranged between the valve core 313 and the first mounting portion 311, the second mounting portion 312 and the valve core 313 are coaxially arranged. Wherein, the front end of the valve core 313 is provided with a diversion hole 3131, and the middle section of the valve core 313 is provided with a diversion groove 3132 communicated with the diversion hole 3131. When the water tank 100 of the present embodiment is used to collect sewage, the sewage is introduced into the guide hole 3131 through the connection pipe and is input into the guide groove 3132, and the water pressure generated in the guide groove 3132 pushes the valve element 313 to move toward the first mounting portion 311 and compresses the spring 314. Since the diameter of the valve core 313 is smaller than the diameter of the inner cavity of the first mounting portion 311, a gap exists between the valve core 313 and the first mounting portion 311, and the sewage flows into the inner cavity of the first mounting portion 311 through the gap between the valve core 313 and the first mounting portion 311, and finally flows into the first cavity 111 through the through hole 3111 of the first mounting portion 311, and is collected by the water tank 100. When the sewage is collected, no water pressure acts in the guide groove 3132, the spring 314 is deformed again, and pushes the spool 313 to move toward the second mounting part 312, and finally returns to the position shown in fig. 9. The distal end surface of the spool 313 abuts against the inner cavity of the second mounting portion 312, thereby preventing the sewage from flowing out of the first cavity 111. In this embodiment, the second water inlet assembly 32 and the first water inlet assembly 31 have the same structure, and are not described herein again.

As shown in fig. 5, the water tank 100 of the present embodiment further includes a first fixing member 118 and a second fixing member (not shown), the first fixing member 118 is disposed on an inner wall surface of the tank 10 near the first through hole, the second fixing member is disposed on an inner wall surface of the tank 10 near the second through hole, and the first water inlet assembly 31 and the second water inlet assembly 32 are connected to the first fixing member 118 and the second fixing member, respectively.

The first fixing member 118 in this embodiment is a mounting plate provided at an interval on the inner wall surface of the body 11, and the first water inlet unit 31 is fixed to the body 11 by connecting the first water inlet unit 31 to the mounting plate by a bolt. In this embodiment, the second fixing member has the same structure as the first fixing member 118, and the connection manner of the second water inlet assembly 32 and the second fixing member is also the same as the connection manner of the first water inlet assembly 31 and the first fixing member 118, which is not described herein again.

In addition, the first fixing member 118 is provided to limit the position of the end point of the partition board 20 in the moving process towards the first cover plate 12, so as to effectively prevent the partition board 20 from being attached to the first cover plate 12. The arrangement of the second fixing member can also limit the position of the end point of the partition board 20 in the moving process towards the second cover plate 13, so that the partition board 20 is effectively prevented from being attached to the second cover plate 13.

For the first use, the water tank 100 is removed from the cleaning apparatus, and the partition 20 is slidably mounted inside the body 11. The first cover plate 12 is fixedly connected to the body 11, and the water tank 100 is inverted, so that the second chamber 112 is disposed above the first chamber 111. The second cover 13 is opened and the partition 20 is pressed down close to the first cover 12, but leaving a space for external sewage (sewage converted from fresh water not supplied from the tank 100). The clean water is injected into the second cavity 112 until the second cavity 112 is nearly filled, and the filled clean water is nearly filled in the second cavity 112, so that the automatic adjustment effect of the water tank 100 is better. After the clean water is filled, the second cover plate 13 is fastened, the water tank 100 is aligned again, so that the first cavity 111 is arranged above the second cavity 112, and the water tank is put into the cleaning device for use.

The second water inlet assembly 32 is in fluid communication with the cleaning apparatus during use. Specifically, the valve core 313 may be pressed outside the housing 10 to form a gap between the valve core 313 and the wall surface of the inner cavity of the first mounting portion 311, and clean water may be pumped out of the second cavity 112 by a water pump for cleaning. While the sewage generated during the cleaning process is continuously sucked into the first chamber 111. In this process, as the amount of clean water in the second chamber 112 decreases, negative pressure is generated in the second chamber 112 to draw the diaphragm 20 downward in the axial direction of the body 11. In the process, the volume of the second cavity 112 is dynamically reduced along with the use of the fresh water, and is always consistent with the residual fresh water, and no space is wasted. The volume of the first cavity 111 is dynamically increased along with the use of the clean water, so that the collection work of the sewage is guaranteed.

After cleaning, the water tank 100 is taken down, and the first water inlet assembly 31 and the second water inlet assembly 32 are automatically closed. The first cavity 111 is opened to pour out the sewage, and then other actions are performed. The second chamber 112 may or may not be opened to allow the remaining fresh water to drain and the diaphragm 20 to be removed for cleaning. The first chamber 111 is typically cleaned and rinsed with fresh water. If the remaining fresh water is poured out and the partition 20 is removed, the entire water tank 100 can be directly flushed.

And after the cleaning is finished, when the cleaning device needs to be used again, the water filling step is repeated.
