[0002] In artificially constructed water storage and swimming areas, regular cleaning is required. Pool robots are automatic pool cleaning devices that can clean pools automatically, freeing up manpower.

[0003] In related technologies, after a pool robot completes its pool cleaning task, the user needs to retrieve the robot from the pool and clean its internal filter basket. Otherwise, excessive accumulation of dirt in the filter basket will cause the pool robot to lose its cleaning ability. However, manually cleaning the filter basket inside the robot is a rather cumbersome process.

[0004] Therefore, it is essential to design an automatic water tank cleaning device and base station capable of automatically cleaning the filter basket. Utility Model Content

[0005] The present invention aims to solve one of the technical problems of the prior art to a certain extent. To this end, the present invention provides an automatic water tank cleaning device and base station capable of automatically cleaning filter baskets.

[0006] Firstly, in order to achieve the above-mentioned objectives, this utility model proposes an automatic water tank cleaning device, including a housing and a filter.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain the invention and should not be construed as limiting the scope of this utility model.

[0029] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this patent. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0030] like Figure 1 As shown, this embodiment proposes an automatic water tank cleaning device, including a housing and a filter 150. The bottom of the housing is provided with a suction port 110 and a water flow channel 120. One end of the water flow channel 120 is connected to the suction port 110, and the other end is connected to the filter 150. A first valve 130 and a second valve 140 are provided on the water flow channel 120. The first valve 130 and the second valve 140 are used to control the on / off state of the water flow channel 120.

[0031] Wherein, the first valve 130 and the second valve 140 are configured as follows:

[0032] When the automatic water tank cleaning equipment cleans the water tank, a water flow is formed in the water flow channel from the suction port 110 to the filter 150, the first valve 130 is closed, and the second valve 140 is opened.

[0033] When the automatic water tank cleaning equipment discharges sewage to an external base station, a water flow is formed in the water flow channel, flowing from the filter 150 to the sewage suction port 110. The first valve 130 is opened and the second valve 140 is closed.

[0034] In this technical solution, a suction port 110 is provided at the bottom of the housing. The housing is recessed inward from the suction port to form a water flow channel 120, thereby connecting the filter 150. That is, one end of the water flow channel 120 is connected to the suction port 110, and the other end is connected to the filter 150. Furthermore, by setting a first valve 130 and a second valve 140 on the water flow channel 120 or the filter 150, the on / off state between the filter 150 and the external environment can be controlled. For example, when the cleaning equipment cleans the pool, the force of the water can open the second valve, and the dirt in the pool enters the filter through the opening after the second valve is opened with the water flow. When the cleaning equipment automatically cleans the filter, the first valve is opened, at which time the water flow channel can connect the filter and the outside, so that the dirt in the filter can be discharged from the water flow channel. When the automatic water tank cleaning equipment switches between water tank cleaning and filter basket self-cleaning, the opening and closing status of the first valve and the second valve are controlled to enable the water tank cleaning equipment to automatically perform water tank cleaning operations, and to discharge dirt from the filter when the dirt accumulates to a certain extent.

[0035] like Figure 2 , 3 As shown, the first valve 130 has an opening, and the second valve 140 is used to open or close the opening. Specifically, the first valve 130 is configured as a hinged door that rotates around a fixed axis, and the second valve 140 is located at the opening of the first valve 130 and controls the opening and closing state of the opening. When the second valve 140 is closed, it covers the opening of the first valve 130, thus closing the opening and blocking the water flow channel 120. When the second valve 140 is open, it opens the opening of the first valve 130, thus connecting the water flow channel 120. By controlling the state of the second valve 140, the on / off control of the water flow channel 120 can be achieved. When the automatic cleaning equipment for the water tank is performing a vacuuming operation, the second valve 140 is opened and the first valve 130 is closed.

[0036] Specifically, such as Figure 2 As shown, the second valve 140 is fixedly connected to the first valve 130, and the second valve 140 is located on the side of the first valve 130 away from the suction port 110. When the automatic pool cleaning equipment performs suction operation, water flows into the equipment through the suction port 110. To facilitate the opening of the second valve 140 during suction operation, the second valve 140 is located on the side of the first valve 130 away from the suction port 110. Flipping the second valve 140 away from the suction port 110 will open the opening on the first valve 130.

[0037] In some embodiments, the first valve 130 is configured as an electric valve; and / or, the second valve 140 is configured as a one-way valve. Specifically, the first valve 130 is driven by a motor to rotate along a fixed shaft, and the rotation direction of the motor's output shaft is controlled by a controller. By controlling the rotation direction of the motor output, the opening and closing state of the first valve 130 can be controlled. The second valve 140 is configured as a one-way valve. When the second valve 140 is open, water can only flow from the suction port 110 along the water flow channel 120 to the filter 150. If water flows from the filter 150 along the water flow channel 120 to the suction port 110, the second valve 140 is forcibly closed. It should be noted that in other embodiments, the first valve 130 can also be configured as an electric valve that extends and closes along one side. The structure shown in the accompanying drawings of this embodiment is only an example and is not intended to limit the specific structure of the first valve 130 and the second valve 140.

[0038] In some embodiments, such as Figure 1 As shown, a drive pump is also installed inside the housing. The drive pump guides water flow into the housing, and the force of the water flow driven by the drive pump can open the second valve 140. The drive pump drives the water in the pool to form a water flow, and drives the water flow from the suction port 110 along the water flow channel 120 into the housing (flowing through the filter 150). When the water flows through the second valve 140, it can push the second valve 140 to flip open into the housing. When the cleaning equipment performs suction operation, the drive pump works, guiding the water flow to open the second valve 140, allowing the water to enter the filter 150. The filter 150 filters out and collects the dirt in the water. The second valve 140 can be made of a soft material such as resin, rubber or silicone. Under the action of water flow (from the outside of the shell to the inside), the second valve 140 made of soft material can be opened relatively easily. At the same time, when water flow is formed from the inside of the shell to the outside and the first valve 130 is closed, the second valve 140 adheres to the first valve 130 due to the obstruction of the first valve 130, so that the opening of the first valve 130 is closed, preventing dirt in the filter basket from flowing out of the second valve 140 when the first valve 130 is closed.

[0039] In some embodiments, the first valve 130 is disposed on the filter 150 or the housing. The first valve 130 may be disposed on the filter 150 or on the housing; in this embodiment, the filter 150 is a filter basket.

[0040] In some embodiments, such as Figure 4 , 5As shown, when the automatic water tank cleaning device is connected to the base station 200, the automatic water tank cleaning device remains in a vertical state. At this time, the dirt in the filter 150 will move to the side of the lowest position of the filter due to gravity, thereby setting the first valve 130 at the lowest position of the filter 150 in this vertical state. When the water flow channel is connected, the dirt accumulated near the first valve 130 is more likely to flow out with the water flow.

[0041] In some embodiments, the filter includes a dirt collection area, and when the automatic water tank cleaning device discharges wastewater to an external base station, the dirt in the filter flows to the dirt collection area, and the first valve 130 is located in or near the dirt collection area.

[0042] Specifically, the filter can be an irregular structure, for example, at least part of the side wall is inclined relative to the horizontal or vertical direction, so that the dirt in the filter flows to the dirt collection area along the inclined side wall.

[0043] In some embodiments, the first valve 130 is rotatably connected to the filter 150, and the automatic water tank cleaning device further includes a control device for controlling the rotation of the first valve 130 to open or close the water flow channel 120.

[0044] Furthermore, this embodiment also proposes a base station, which includes a sludge extraction device configured to extract sludge from the filter 150 in the automatic water tank cleaning equipment as described in any of the above embodiments. Figure 4 , 5 As shown, the base station is equipped with a sludge suction device. When the automatic water tank cleaning equipment runs to the base station, the sludge suction device of the base station is aligned with the sludge suction port 110 of the cleaning equipment. The drive pump inside the cleaning equipment stops working, and the control device of the cleaning equipment controls the first valve 130 to open. The sludge suction device starts working and sucks out the dirt collected in the filter 150 along the water flow channel 120.

[0045] In summary, the above embodiments of this application control whether the filter 150 is spatially connected to the outside by setting a first valve 130 and a second valve 140 in the water flow channel 120 between the suction port 110 and the filter 150, so that when the cleaning equipment cleans the pool, the dirt in the pool is sucked into the filter 150; when the filter 150 needs to be automatically cleaned, the dirt in the filter 150 can be discharged from along the water flow channel.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this invention will be included within the scope of the claims.
