[0037] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Example 1:
[0038] like Figures 1 to 6As shown, a hydrodynamic quantitative liquid supply device includes a main body 10, which has a movable component 20. One side of the movable component 20 cooperates with the main body 10 to form a compression chamber 11, and the other side of the movable component 20 cooperates with the main body 10 to form a liquid suction chamber 12. It also includes a water inlet channel 13. The movable component 20 can move under the water pressure of the water inlet channel 13. During the water intake process of the water inlet channel 13, the movable component 20 is pushed to move in the positive direction to compress the compression chamber 11 and cause the liquid suction chamber 12 to generate negative pressure. It also includes a liquid suction channel 14 and a liquid outlet channel 15 connected to the liquid suction chamber 12. When the liquid suction chamber 12 generates negative pressure, liquid can be drawn into the liquid suction chamber 12 through the liquid suction channel 14. When the water inlet channel 13 is cut off, the movable component 20 moves in the opposite direction and squeezes the liquid suction chamber 12. The liquid in the liquid suction chamber 12 is discharged through the liquid outlet channel 15.
[0039] In this embodiment, a reset spring 30 is provided in the compression chamber 11. The reset spring 30 provides an elastic force to the movable member 20 to move in the opposite direction. Specifically, the reset spring 30 abuts between the main body 10 and the movable member 20. When water enters the water inlet channel 13, the movable member 20 moves in the forward direction to compress the reset spring 30. When the water inlet channel 13 is cut off, the reset spring 30 resets and pushes the movable member 20 to move in the opposite direction.
[0040] In this embodiment, the main body 10 is provided with a water inlet cavity 16, which is connected to the water inlet channel 13. The movable component 20 is provided with a driving part 21 corresponding to the water inlet cavity 16. The main body 10 is also provided with a movable cavity 17. The driving part 21 moves along the movable cavity 17. The water pressure of the water inlet cavity 16 drives the driving part 21, thereby driving the movable component 20 to move.
[0041] In this embodiment, a water inlet diaphragm 40 is provided between the water inlet cavity 16 and the drive unit 21, and the water inlet diaphragm 40 seals and isolates the water inlet cavity 16 and the drive unit 21.
[0042] In this embodiment, the main body 10 includes a liquid-absorbing body 10a, which includes an upper mounting part and a lower mounting part, as well as a liquid-absorbing tube 14a and a liquid-discharging tube 15a located on both sides.

The main body also includes an upper cover 11a and a lower cover 12a. The upper cover 11a is fixedly installed on the upper mounting part and cooperates with the movable part 20 to form the compression cavity 11.

The liquid absorption cavity 12 is located on the outer periphery of the movable cavity 17. Specifically, the lower cover 12a is provided with a water inlet pipe 13a, and the water inlet channel 13 is disposed in the water inlet pipe 13a. The liquid absorption body 10a is provided with an annular partition 16a. The partition 16a radially separates the inner cavity of the liquid absorption body 10a into the movable cavity 17 and the liquid absorption cavity 12.
[0043] In this embodiment, the movable component 20 includes a liquid-absorbing membrane 22, the outer periphery of which is fixed to the body. The compression chamber 11 is located on one side of the liquid-absorbing membrane 22, and the liquid-absorbing chamber 12 is located on the other side of the liquid-absorbing membrane 22. Specifically, the outer periphery of the liquid-absorbing membrane 22 is pressed between the liquid-absorbing body 10a and the upper cover 11a.
[0044] In this embodiment, a first one-way valve 60 is installed on the liquid suction channel 14, and a second one-way valve 70 is installed on the liquid outlet channel 15. When the liquid suction channel 14 suctions liquid, the first one-way valve 60 is opened and the second one-way valve 70 is closed. When the movable member 20 squeezes the liquid suction chamber 12, the first one-way valve 60 is closed and the second one-way valve 70 is opened.
[0045] The specific working process of this embodiment:
[0046] like Figure 5 As shown, during the water intake process, the movable part 20 is pushed to compress the return spring 30 and move in the positive direction. By compressing the compression chamber 11, the volume of the liquid suction chamber 12 is expanded, thereby generating negative pressure in the liquid suction chamber 12. Under the action of negative pressure, the liquid suction chamber 12 is drawn into the liquid suction chamber 12 by the liquid suction channel 14.
[0047] like Figure 6 As shown, when the water inlet channel 13 is cut off, the movable part 20 moves in the opposite direction under the restoring force of the return spring 30 and squeezes the liquid suction chamber 12, so that the liquid in the liquid suction chamber 12 is discharged through the liquid outlet channel 15. Example 2:
[0048] like Figure 7 and Figure 8As shown, the main difference between this embodiment and the first embodiment is that the main body 10 includes a lower body 10b and an upper cover 11b. The lower body 10b has a movable cavity 17 at its bottom and a liquid absorption cavity 12 located on the outer periphery of the movable cavity 17. The movable component 20 is located on the upper part of the lower body 10b and cooperates with the upper cover 11b to form the compression cavity 11. In this embodiment, a sealing component 50 is provided between the driving part 21 and the movable cavity 17. The driving part 21 and the movable cavity 17 are in a sealed sliding fit. Specifically, the driving part 21 has a limiting groove on its outer periphery, and the sealing component 50 is a sealing ring fitted on the limiting groove.
[0049] In this embodiment, the bottom of the lower body 10b is provided with a water inlet channel 13, and the liquid suction channel 14 and the liquid outlet channel 15 are located at the bottom of the lower body 10b.
[0050] The specific working process of this embodiment is the same as that of Embodiment 1. Example 3:
