In some embodiments of the present application, features in the following examples and examples may be combined with each other without conflict.

The water tank 300 provided by the embodiment of the present application is installed on a cleaning device, referring to fig. 1, the cleaning device 10 has a main body 100 and a chassis 200, the main body 100 is rotatably disposed on the chassis 200, the main body 100 may have a handle 110 for a user to hold, and during operation of the cleaning device 10, the user holds the handle 110 and pushes the chassis 200 by using the main body 100 to control the cleaning device 10 to move forward, backward or turn, so as to clean a surface to be cleaned by using the cleaning member 210 on the chassis 200. Typically, the cleaning device 10 has a clean water tank that supplies water to the cleaning elements 210 or the floor surface, and a dirty water tank that allows the cleaning elements 210 to better clean the dirt on the floor surface. During cleaning, the cleaning device 10 can utilize the first suction device 400 (e.g., a negative pressure source such as a fan) to recycle the generated dirt to a water tank (e.g., a waste water tank).

The first suction device 400 is usually a fan or other device capable of generating negative pressure in the cleaning apparatus 10, and the first suction device 400 is used for providing power for sucking dirt generated during the operation of the cleaning apparatus 10 back to the water tank, however, the dirt usually contains water or vapor, and the water or vapor is easy to pass through into the first suction device 400, so as to cause damage to the first suction device 400 or liquid leakage. Therefore, the embodiment of the application is improved as follows:

as shown in fig. 2 to 6, the housing 310a is formed with a receiving chamber 310; the housing 310a may be provided with a suction port 317, and the suction port 317 serves to communicate the first suction device 400 with the receiving chamber 310. The first suction device 400 provides a suction power to the receiving chamber 310 through the suction port 317 so that external contaminants can be sucked into the receiving chamber 310. It should be noted that, in order to reduce the possibility of water entering the first suction device 400, a hypaete device 500 capable of blocking water vapor may be arranged between the air suction port 317 and the first suction device 400.

Illustratively, as shown in fig. 4 to 5, the housing 310a includes a top wall 310b and a side wall 310c, wherein the suction port 317 is provided at the top wall 310b with a space between an edge of the suction port 317 and the side wall 310 c. During the suction of the first suction apparatus 400, water on the sidewall 310c may enter the first suction apparatus 400 by moving upward along the sidewall 310c according to the suction force of the first suction apparatus 400. The present embodiment can reduce the probability of liquid entering the first suction device 400 directly from the suction port 317 by maintaining a distance between the edge of the suction port 317 and the side wall 310c, so that the water on the side wall 310c can be blocked by the top wall 310b between the edge of the suction port 317 and the side wall 310c when moving upwards along the side wall 310c, that is, the distance forms a space for the liquid to drop in a buffering manner, so as to prevent the water from directly entering the suction port 317 upwards along the side wall 310 c.

In an alternative embodiment, a soil pick-up pipe 112 is further included, and an outlet of the soil pick-up pipe 112 is communicated with the accommodating chamber 310 to allow external liquid to enter the accommodating chamber 310. The outlet 112c of the soil pick-up pipe 112 communicates with the housing chamber 310. The soil suction pipe 112 may include a soil suction pipe (not shown) and a soil inlet pipe 112b, the soil suction pipe 112a is disposed outside the water tank at the bottom chassis 200 and the main body 100 of the cleaning device 10, and the soil inlet pipe 112b is disposed inside the water tank 300, and a water outlet of the soil inlet pipe 112b, i.e., an outlet 112c of the soil suction pipe, is used to drive soil from the outside into the receiving chamber 310. The first suction device 400 can suck gas to form a negative pressure through the suction port 317, the accommodating chamber 310, and the dirt suction duct 112 in order to suck external dirt into the accommodating chamber 310.

It should be noted that the external liquid described in the embodiments of the present application may be dirt (dirt includes a solid-liquid mixture and sewage), or may be clean water. The first pumping device 400 of the embodiment of the present application mainly provides driving power for external liquid to enter the accommodating chamber 310. Wherein the outside means a portion other than the water tank.

When the sucked liquid is sewage or a solid-liquid mixture, the water tank 300 is a sewage tank, and the first suction device 400 can recycle the sewage generated during the cleaning process of the cleaning apparatus 10 to the sewage tank for the convenience of the subsequent treatment of the user.

When the sucked liquid is clean water, at this time, the first suction means 400 may suck external clean water into the accommodating chamber 310. The clean water may clean the holding chamber 320 for maintenance of the water tank.

Hereinafter, the following description will be given mainly taking an example in which the external liquid is a solid-liquid mixture or sewage.

The first suction device 400 can be used for sucking external dirt (including solid-liquid garbage, sewage and the like) in the cleaning process of the cleaning device 10 into the accommodating cavity 310 so as to recover dirt, oil stain or impurities on the ground. The cleaning device 10 may further pump a mixture of external solid waste and sewage into the accommodating cavity 310, which is not limited in this application. The chassis 200 of the cleaning device 10 is provided with a cleaning element 210 for cleaning a surface to be cleaned, the cleaning element 210 may be a cleaning member such as a rolling brush, one end of the main body 100 is provided with a handle 110 for a user to hold, and the user holds the handle 110 to drive the main body 100 to push the chassis 200 to move forward and backward or turn. The first suction device 400 communicates with the receiving chamber 310 such that the first suction device 400 can provide a power to drive external liquid into the receiving chamber 310. For example, the first suction device 400 may be a fan or the like capable of providing a large negative pressure, so as to be capable of sucking the contaminated water generated by the cleaning of the surface to be cleaned by the cleaning apparatus or the contaminated water mixed with the solid impurities into the accommodating chamber 310.

The top wall 310b of the first housing 310a is provided with a water blocking structure 318, and the water blocking structure 318 is used for blocking liquid from entering the air suction opening 317.

For example, as shown in fig. 3, the water blocking structure 318 may include a first water blocking portion 318a, and the first water blocking portion 318a is located at the rear side of the air suction opening 317 to block the liquid oscillating from the rear side to the air suction opening 317 in the accommodating chamber 310, especially when the main body 100 is inclined or laid down, the liquid flowing to the rear side results in a high base water level, and when the liquid may further oscillate upwards along with the oscillation, the liquid can be blocked by the first water blocking portion 318a located at the rear side of the air suction opening 317. Alternatively, the first water guard portion 318a is disposed in the left-right direction.

In an alternative embodiment, as shown in fig. 3, the water blocking structure 318 includes a second water blocking portion 318b, the second water blocking portion 318b is located between the air suction opening 317 and the side wall 310c of the housing 310a, and a gap is formed between the second water blocking portion 318b and the side wall 310c of the housing 310a to block the wall-hanging liquid on the top wall 310b and the side wall 310 c. For example, the second water retaining portion 318b is a wall surface extending downward from the top wall 310b, the wall surface may be a flat surface or an arc-shaped surface, and is disposed on the peripheral side of the suction port 317, so that during the suction process of the suction port 317 on the accommodating chamber 310, water drops or a water film may be sucked upward along the side wall 310c due to the surface tension of water, and the second water retaining portion 318b can prevent the water drops or the water film from continuously flowing along the top wall 310b and entering the suction port 317.

In some embodiments, the water-retaining structure 318 further comprises a third water-retaining portion 318c, and the third water-retaining portion 318c is located between the suction opening 317 and the outlet 112c of the dirt suction duct 112.

In an alternative embodiment, the outlet 112c of the dirt suction pipe communicates with the accommodating chamber 310, and the water blocking structure 318 includes a fourth water blocking portion 318d (fig. 6), the fourth water blocking portion 318c is located between the suction opening 317 and the outlet 112c of the dirt suction pipe, and is used for blocking the liquid at the outlet 112c of the dirt suction pipe from being directly drawn into the suction opening 317. Illustratively, as shown in fig. 4b and 5, the fourth water-blocking portion 318d is an annular enclosure disposed at the top of the accommodating chamber 310, and the lower edge thereof is located below the outlet 112c of the sewage suction pipe.

It should be noted that the first water stopper 318a, the second water stopper 318b and the third water stopper 318c may be integrally connected to each other; the whole may be arranged around at least part of the suction opening 317. Illustratively, the entirety is cylindrical. The water blocking structure may be a circular ring, a rectangular frame, or a polygonal frame, and is disposed around the suction port 317. The purpose of the water-retaining portion 318 is mainly to block the liquid from entering the air suction opening 317 from the first chamber 310, and as for the structural form thereof, the present application is not limited as long as the function of blocking the liquid from entering the air suction opening 317 from the first chamber 310 can be achieved. In some embodiments, only one or two of the first water stopper portion 318a, the second water stopper portion 318b, and the third water stopper portion 318c may be provided.

Illustratively, the fourth water stopper 318d is closer to the outlet 112c of the sewage suction pipe 112 than the third water stopper 318c along the left-right direction of the housing, and the lower edge of the third water stopper 318c is higher than the lower edge of the fourth water stopper 318 d. In this way, the liquid coming out of the outlet 112c of the dirt suction pipe 112 can flow directly to the position below the accommodating chamber 310 as much as possible, and the risk of the liquid bypassing the fourth water stop 318d and entering the air suction port 317 is reduced.

In an alternative embodiment, referring to fig. 4, the air inlet 317 may be located at the front side of the accommodating chamber 310 to reduce the probability of liquid flowing into the air inlet 317 from the accommodating chamber 310 when the main body 100 is in a tilted or lying state, and when the main body 100 is lying down, the air inlet 317 located at the front side can be located above the accommodating chamber 310 in the lying state and is far away from the liquid level in the lying state to prevent the liquid in the accommodating chamber 310 from flowing into the air inlet 317 in the lying state.

In an alternative embodiment, there are two suction ports 317, the two suction ports 317 are respectively located at the two sides of the outlet 112c of the dirt suction pipe in the left-right direction, the arrangement is made in sequence to make the space inside the accommodating chamber 310 more compact, and the dirt suction pipe 112 and the suction ports 317 can be arranged at the same side of the accommodating chamber 310 (i.e. both located at the front side of the accommodating chamber 310); when the dirt suction pipe 112 and the suction opening 317 are arranged at the front side of the accommodating cavity 310, when the main body 100 lies down, the outlet 112c and the suction opening 317 of the dirt suction pipe can both be located at the upper side of the accommodating cavity 310, and are far away from the liquid level in the accommodating cavity 310 at the moment, so that the liquid in the accommodating cavity 310 is prevented from flowing back to the suction opening 317 or flowing back to the surface to be cleaned along the outlet 112c of the dirt suction pipe.

In an alternative embodiment, the outlet 112c of the dirt suction pipe is located at the front side of the accommodating chamber 310 to prevent the liquid in the accommodating chamber 310 from flowing back to the ground along the outlet 112c of the dirt suction pipe when the main body 100 is in the inclined or lying state, and the outlet 112c of the dirt suction pipe is located at the upper side of the accommodating chamber 310 far from the liquid level in the accommodating chamber 310.

In an alternative embodiment, the outlet 112c of the dirt suction pipe is located above the lower edge of the fourth water retaining portion 318d, and can change the direction of the fluid (including the water flow and the air flow) by 180 degrees, change the fluid from upward to downward, change the fluid from downward to upward after being sucked through the upper air suction port 317, and throw the liquid mixed in the air flow out through two changes of direction, thereby assisting the liquid-gas separation in the accommodating chamber 310.

The fourth water blocking portion 318d may have a circular, rectangular, or polygonal shape and is disposed around the outlet 112c of the sewage suction pipe. In some embodiments, the number of the fourth water-retaining portions 318d may be at least two, and the number of the first water-retaining portion 318a, the second water-retaining portion 318b and the third water-retaining portion 318c is not limited.

In some embodiments, the outlet 112c of the dirt suction pipe has a height higher than the height of the rear side (as shown in fig. 2), so that the dirt coming out from the dirt suction pipe 112 can be guided to the rear side, and because the dirt suction pipe 112 is disposed at the front side, the dirt flowing out from the outlet 112c of the dirt suction pipe can enter a larger space at the rear side of the dirt suction pipe 112, and the outlet 112c of the dirt suction pipe is prevented from being blocked.

In other embodiments, the height of the rear side of the outlet 112c of the dirt suction pipe is higher than that of the front side, when the main body 100 tilts and lies down, the height of the rear side of the outlet 112c of the dirt suction pipe is higher than that of the front side, so that a barrier can be formed in the outlet from the rear side to the front side, and the risk that liquid in the accommodating cavity 310 flows back from the front side of the outlet of the dirt suction pipe 112 closer to the liquid level when the main body 100 is in a tilting and lying down state can be effectively reduced.

It will be appreciated that the outlet 112c of the dirt suction pipe is inclined to redirect the flow of gas or liquid out of the outlet of the dirt suction pipe 112 and prevent the gas or liquid from directly impacting the ceiling of the receiving chamber 310.

As shown in fig. 1, the present embodiment also provides a cleaning device 10, which includes a chassis 200, a main body 100, and a first suction device; the main body 100 is rotatably coupled to the chassis 200, and a water tank as provided in the above embodiment.

It should be noted that the structure and function of the water tank in the cleaning device provided in the embodiment of the present application are the same as those in the above embodiment, and specific reference may be made to the description of the above embodiment, and details are not repeated in this embodiment.

While the invention has been described with reference to specific embodiments, the scope of the invention is not limited thereto, and those skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the invention. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
