Cleaning devices are typically equipped with a water tank to provide an adequate source of water when mopping the floor. The water tank is communicated with the water pumping power device through a water pipe, and water in the water tank is controllably supplied to a water using part of the cleaning equipment through the water pumping power device. After the water pumping power unit stops supplying water to the water using site, there are generally the following problems: (1) After the water pumping power device stops supplying water to the water using part, the water in the water tank still flows out all the time under the siphon effect; (2) When the water pipe is broken due to uncontrollable factors, water in the water tank can flow outwards all the time under the siphon action. If the leaked water is light, the floor inside the household is damaged, if the leaked water is heavy, the household is flooded, and potential safety hazards can occur when the leaked water touches the electrified components.

To solve the above problems, cleaning apparatuses are generally provided with an anti-siphon structure, such as:

in some related technologies, an air charging power device is installed at the highest position of a water pipe, and after the water pumping power device stops supplying water to a water using position, the air charging power device charges air into the water pipe, so that water in the water pipe flows back to a water tank under the action of air pressure, and a siphon effect is blocked. However, the cost of installing the inflation power device is high, and the cost performance of the product can be greatly reduced.

In other related art, a one-way valve is provided at an outlet of the pumping power unit, and after the pumping power unit stops supplying water to the water using part, water inside the water tank stops flowing under the effect of blocking capacity of the one-way valve. However, the limitation of arranging the one-way valve is large, and if the one-way valve has strong blocking capability, the flow of the pumping power device can be influenced; if the blocking capability of the one-way valve is weak, the anti-siphon effect is not obvious.

In view of this, the present utility model provides, in order to at least partially solve the above-mentioned problems, a cleaning apparatus comprising: a liquid storage tank for storing cleaning liquid; the pipeline component is arranged on the liquid storage tank; the power piece is communicated with the pipeline assembly and is used for extracting the cleaning liquid in the liquid storage tank; the pipeline assembly is provided with an air inlet hole, and the air inlet hole is used for enabling air to enter the pipeline assembly through the air inlet hole to block siphoning after the power piece stops extracting cleaning liquid in the liquid storage tank.

According to the cleaning equipment disclosed by the utility model, after the power piece stops extracting the cleaning liquid in the liquid storage tank, gas enters the pipeline assembly through the air inlet, and the cleaning liquid below the air inlet in the pipeline assembly flows back into the liquid storage tank under the action of the gas pressure, so that the siphon blocking effect is achieved.

In order to provide a thorough understanding of the present utility model, detailed structures will be presented in the following description in order to illustrate the technical solutions presented by the present utility model. Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

The cleaning apparatus 100 may be a cleaning robot, a hand-held cleaning device, a base station, or the like, which is not limited.

The cleaning liquid may be water, a cleaning agent or a mixture of water and cleaning agent, etc., and accordingly, the power member 130 may be a water pump or other liquid delivery device, and the power member 130 may be selected according to the type of cleaning liquid, which is not limited.

When the power piece 130 works, the cleaning liquid in the liquid storage tank 110 is pumped through the pipeline assembly 120 and is conveyed to a water use part; after the power piece 130 stops working, air enters the inside of the pipeline assembly 120 through the air inlet hole 140 on the pipeline assembly 120, the cleaning liquid in the pipeline assembly 120 is divided into an upper part and a lower part from the air inlet hole 140, the cleaning liquid above the air inlet hole 140 continuously flows to the power piece 130, the cleaning liquid below the air inlet hole 140 flows back to the liquid storage tank 110 under the action of air pressure, so that the liquid level in the liquid storage tank 110 and the liquid level in the pipeline assembly 120 tend to be consistent, and the siphon blocking effect is achieved.

Based on this, a cleaning device 100 having an anti-siphon function is provided. According to the cleaning device 100 of the present utility model, after the power member 130 stops pumping the cleaning liquid in the liquid storage tank 110, the gas enters the inside of the pipeline assembly 120 through the gas inlet 140, and the cleaning liquid under the gas inlet 140 in the pipeline assembly 120 flows back into the liquid storage tank 110 under the action of the gas pressure, so as to achieve the effect of blocking siphoning. The air inlet hole structure adopted by the utility model is a pure mechanical device without electric control, and has the advantages of simple structure, small occupied space, extremely low cost and longer service life.

Taking the cleaning apparatus 100 as a handheld cleaning device for example, the water-using portion may be a floor to be cleaned, and the power unit 130 may draw the cleaning liquid in the liquid storage tank 110 to the floor to be cleaned when working, so that the handheld cleaning device performs wet cleaning on the floor to be cleaned.

In one embodiment of the present utility model, the air inlet 140 is located at a height higher than the level of the cleaning liquid in the liquid storage tank 110. Specifically, after the power piece 130 stops pumping the cleaning liquid in the liquid storage tank 110, the air inlet hole 140 should be located above the liquid surface of the cleaning liquid so that the air can enter the pipe assembly 120 through the air inlet hole 140.

In one embodiment of the present utility model, the cleaning apparatus 100 further includes a filter 150, where the filter 150 is disposed on the pipe assembly 120 and corresponds to the air inlet 140, and is configured to filter the air before the air enters the air inlet 140. By providing the filter 150, the gas entering the gas inlet hole 140 from the outside of the pipe assembly 120 can be filtered to remove large particle impurities in the gas, thereby avoiding blocking the gas inlet hole 140. The filter 150 may be a filter plate, a screen, or the like, and is not limited thereto.

In one embodiment of the present utility model, the pipe assembly 120 includes a pipe body 121 and a pipe bracket 122 communicating with each other, the pipe body 121 is assembled to the tank 110 through the pipe bracket 122, and the power member 130 communicates with the pipe body 121 through the pipe bracket 122.

In one example, the tank 110 includes a tank case 111 having an accommodation space for accommodating the cleaning liquid and a tank case cover 112 mounted to the tank case 111 for closing the accommodation space. Wherein, the pipeline bracket 122 can be assembled on the liquid storage tank cover 112, the pipeline main body 121 is located inside the liquid storage tank 110, one end of the pipeline bracket 122 is located inside the liquid storage tank 110 and is communicated with the pipeline main body 121, and the other end is located outside the liquid storage tank 110 and is communicated with the power piece 130. It should be noted that, in order to ensure that the cleaning liquid can enter the pipe body 121, the bottom of the pipe body 121 is not abutted against the inner bottom wall of the liquid storage tank 110, and a certain gap exists between the bottom and the bottom, so that the cleaning liquid can enter the pipe body 121; alternatively, the bottom of the pipe body 121 may be abutted against the inner bottom wall of the liquid storage tank 110, but a liquid inlet hole for the cleaning liquid to enter is provided at the bottom of the pipe body 121; or the bottom of the pipe body 121 may be abutted against the inner bottom wall of the liquid storage tank 110, but the bottom of the pipe body 121 is configured as a bevel through which the cleaning liquid may enter the pipe body 121; alternatively, the cleaning liquid may be introduced into the pipe body in other configurations, which are not limited thereto.

In one example, the air intake aperture 140 is provided in the conduit bracket 122. It should be understood that the air inlet hole 140 may be located on the pipe support 122 inside the liquid storage tank 110 or on the pipe support 122 outside the liquid storage tank 110, which is not limited.

In another example, the air intake hole 140 is provided in the pipe body 121.

In one embodiment of the present utility model, the pipeline bracket 122 includes a bracket body 1221 and a bracket inner tube 1222 disposed in the bracket body 1221, the bracket inner tube 1222 is assembled to the liquid storage tank 110 through the bracket body 1221, and the bracket inner tube 1222 is connected with the pipeline body 121 in an interference manner.

In one example, the tank cover 112 is provided with a through hole, the inner tube 1222 of the bracket is inserted into the through hole, one end of the inner tube 1222 of the bracket located inside the tank 110 is communicated with the pipe body 121, and one end located outside the tank 110 is communicated with the power unit 130. The inner tube 1222 is fixedly connected to the tank cover 112 through the main body 1221, wherein the fixing connection may be a bolt connection, welding, gluing, etc., which is not limited thereto.

In one example, the interference connection between the bracket inner tube 1222 and the pipe body 121 may be, but not limited to, that between the bracket inner tube 1222 and the pipe body 121, the bracket inner tube 1222 is assembled in the pipe body 121, or that between the pipe body 121 and the bracket inner tube 1222, the bracket inner tube 1222 is assembled in the pipe body 121.

In one embodiment of the present utility model, the bracket body 1221 has a bracket opening 1223 thereon, and the air intake hole 140 is provided in the bracket inner tube 1222 and corresponds to the bracket opening 1223. The bracket opening 1223 is provided to avoid the bracket inner tube 1222 from covering the air intake hole 140, so that the inside of the bracket inner tube 1222 may communicate with the outside through the air intake hole 140 and the bracket opening 1223.

In one embodiment of the utility model, the filter 150 is disposed in the bracket opening 1223. The filter 150 may be detachably disposed in the bracket opening 1223, or may be fixedly disposed in the bracket opening 1223. The gas entering the bracket opening 1223 from the outside of the manifold assembly 120 is filtered by the filter 150, thereby avoiding the gas from clogging the inlet vents 140.

In one embodiment of the present utility model, the aperture of the inlet aperture 140 is positively correlated with the height at which it blocks siphoning. In other words, the larger the aperture of the air intake hole 140, the higher the height of blocking the siphon. Of course, it is understood that the bore diameter of the inlet aperture 140 cannot be infinite, and cannot exceed the pipe inner diameter of the pipe assembly 120 at maximum. Illustratively, the air intake aperture 140 is provided in the inner tube 1222 of the holder, and the aperture of the air intake aperture 140 cannot exceed the inner diameter of the inner tube 1222 of the holder at maximum.

In one embodiment of the utility model, the power member 130 may be in communication with the bracket inner tube 1222 through a drain tube. When the power piece 130 works, cleaning liquid in the liquid storage tank 110 enters the bracket inner pipe 1222 through the main body 121, then enters the power piece 130 through the liquid outlet pipe, and is conveyed to a water using position by the power piece 130, and the state of the cleaning liquid in the pipeline assembly 120 is shown in fig. 4 (a); when the power piece 130 stops working, the gas enters the air inlet hole 140 after being filtered by the filtering piece 150, and then enters the inner tube 1222 of the bracket through the air inlet hole 140, the cleaning liquid in the inner tube 1222 of the bracket is divided into an upper part and a lower part by the air inlet hole 140 under the action of the gas pressure, and the state of the cleaning liquid in the pipeline assembly 120 is shown in fig. 4 (b); the cleaning liquid above the air inlet 140 continues to flow to the power unit 130, and the cleaning liquid below the air inlet 140 flows back to the liquid storage tank 110 under the action of the air pressure, so as to achieve the effect of blocking siphoning, and the state of the cleaning liquid in the pipeline assembly 120 is shown in fig. 4 (c).

In summary, according to the cleaning device of the embodiment of the utility model, after the power piece stops extracting the cleaning liquid in the liquid storage tank, the gas enters the pipeline assembly through the gas inlet, and the cleaning liquid below the gas inlet in the pipeline assembly flows back into the liquid storage tank under the action of the gas pressure, so that the siphon blocking effect is achieved. The air inlet hole structure adopted by the utility model is a pure mechanical device without electric control, and has the advantages of simple structure, small occupied space, extremely low cost and longer service life.
