[0047] The first channel 70 forms a flow path for the liquid. The liquid enters from one end of the first channel 70 and leaves the first channel 70 from the first opening 60 at the other end, thereby realizing the flow of the liquid. The shape of the first plug 40 can be a sphere, a cube, a cylinder and a cone. The first plug 40 is movable in the first channel 70, and can move from the other end of the first channel 70 to the first opening 60; it can also move from the first opening 60 of the first channel 70 to the other end of the first channel 70. When the first plug 40 moves to the first opening 60, the first plug 40 blocks the first opening 60, the liquid suction component 2 is in the first blocking state, and the liquid suction component 2 stops sucking liquid, which can prevent empty suction; when the first plug 40 leaves the first opening 60, the first plug 40 no longer blocks the first opening 60, the liquid suction component 2 releases the first blocking state, and the liquid suction component 2 continues to suck liquid.

[0048] In one embodiment, the liquid suction component 2 includes a first tube body 50 and a first plug body 40. The first tube body 50 encloses a first channel 70.

The first tube body 50 is provided with a first liquid inlet hole 30, and the first liquid inlet hole 30 is connected to the first channel 70 for suction.

[0049] Optionally, the first tube body 50 and the first plug body 40 in this solution can be regarded as valves to control the entry of liquid. The first tube body 50 encloses the first channel 70 and opens the first liquid inlet hole 30. The opening of the first liquid inlet hole 30 can be drilling, cutting, laser cutting, injection molding. The first liquid inlet hole 30 is opened as the inlet of the liquid. The liquid enters the first channel 70 through the first liquid inlet hole 30 and leaves the first channel 70 from the first opening 60. The cross-sectional shape of the first tube body 50 can be circular, square, or hexagonal. Preferably, the cross-sectional shape of the first tube body 50 in the utility model is circular.

In a preferred embodiment, the side of the first tube body 50 away from the first opening 60 gradually widens and expands. In the utility model, the flared extension design can change the cross-sectional area of ​​the first tube body 50 and adjust the liquid flow rate. When the inner diameter is enlarged, the space for the liquid to flow increases, the flow rate can be slowed down, and the overall flow rate can be adjusted; the speed of liquid passage can be reduced, the pressure of the liquid can be reduced, and the pressure change generated when the liquid flows can be reduced; the expansion of the pipeline can reduce the resistance of the liquid when it passes through, and the liquid can flow smoothly through the pipeline, reducing the energy loss when the fluid flows.

The benefit of the detachable connection is that the first tube body 50 and the second tube body 51 can be easily disassembled and replaced with the connector 22, which is conducive to maintaining and repairing the system. The first tube body 50, the second tube body 51 and the connector 22 can be formed separately, and then detachably connected and assembled to reduce the manufacturing difficulty.

[0073] In one embodiment, the detachable connection between the first tube body 50 and the second tube body 51 and the connecting member 22 is a threaded connection, and at least a portion of the first tube body 50 and / or the second tube body 51 extends into the connecting member 22 .

[0074] Please refer to Fig.14 and Fig.15AA is the cross section of the first tube 50. The first tube 50 and the second tube 51 are connected to the connector 22 by threads. The threaded connection provides a firm connection method, so that the first tube 50 and the second tube 51 are tightly connected to the connector 22 and are not easy to loosen; it provides good liquid sealing performance to prevent liquid leakage; the threaded connection is easy to operate, and the connection or disassembly can be completed by rotating the first tube 50 and the second tube 51 and the connector 22, which is convenient and practical. At least part of the first tube 50 and / or the second tube 51 extends into the connector 22, which can increase the connection depth and improve the stability and reliability of the connection.

[0075] In one embodiment, the connector 22 includes a three-way connector 22A and a third tube body 22B. The three-way connector 22A has three connection ports. The three-way connector 22A is respectively connected to the first tube body 50, the second tube body 51 and the third tube body 22B.

[0076] The first tube body 50, the second tube body 51 and the third tube body 22B are connected to the three-way joint 22A respectively. The three-way joint 22A merges the liquid absorbed from the first channel 70 and the second channel 71 into the third channel 72. The three-way joint 22A can reduce the connection points between the first channel 70, the second channel 71 and the third channel 72, reduce the risk of leakage of the system, and improve the reliability and stability of the entire system. The third tube body 22B connects the liquid absorbed in the third channel 72 to the outside and outputs it to the outside of the liquid suction component. The first tube body 50 and the second tube body 51 are respectively connected to the opposite ends of the connecting member 22. The first tube body 50 and the second tube body 51 are arranged in a divergent manner. When the liquid storage tank 10 tilts and drives the liquid surface to tilt, there is a height difference between the first channel 70 and the second channel 71. At least part of the first channel 70 and / or the second channel 71 is below the liquid surface, providing at least one flow channel, which can prevent empty suction when going up and down the slope.

[0077] In one implementation, the first plug body 40 is a sphere, and the diameter of the first plug body 40 is greater than the inner diameter of the first opening 60 .

[0078] The first plug body 40 is designed to be able to roll, so the shape is designed to be a sphere. The benefit of the sphere in the utility model is that the rolling resistance of the sphere is smaller than that of other shapes, which can reduce the flow resistance of the liquid in the channel and maintain the stable flow of the fluid; balance the flow of the liquid and reduce the unevenness of the liquid flow; the rolling of the sphere can partially or completely cover the opening, thereby controlling the flow of the liquid. The diameter of the first plug body 40 is larger than the inner diameter of the first opening 60, which can accurately control the liquid flow, limit the amount of liquid passing through the first opening 60, and ensure that the liquid can be more reliably controlled when flowing; effectively block the first opening 60 to reduce the risk of liquid leakage or uncontrolled outflow.

[0079] In one implementation, please refer to Fig.16 and Fig.17 , AA is the cross section of the first tube body 50. In the uphill working condition, the liquid in the liquid storage tank 10 flows to the end close to the first tube body 50 under the action of gravity. In the uphill working condition, the first plug body 40 moves away from the first opening 60 under the action of gravity, and the first opening 60 is opened. The second plug body 41 in the second tube body 51 moves close to the second opening 61 under the action of gravity, and the second opening 61 is closed. The first tube body 50 absorbs liquid, and the second tube body 51 does not absorb liquid. In the downhill working condition, the liquid in the liquid storage tank 10 flows to the end close to the second tube body 51 under the action of gravity. In the downhill working condition, the first plug body 40 in the first tube body 50 moves close to the first opening 60 under the action of gravity, and the first opening 60 is closed. The second plug body 41 in the second tube body 51 moves away from the second opening 61 under the action of gravity, and the second opening 61 is opened. The first tube body 50 does not absorb liquid, and the second tube body 51 absorbs liquid.

The shape of the liquid storage tank 10 can be rectangular, cylindrical, elliptical, or square. Optionally, the shape of the liquid storage tank 10 can be rectangular or cylindrical. Preferably, the shape of the liquid storage tank 10 can be rectangular.
