[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1: An anti-clogging automatic rebound pump head, such as Figure 1 - Figure 4 As shown, the device includes a storage cylinder 1 and a piston rod 2 slidably installed inside the storage cylinder 1. A connecting cylinder 3 is installed at the lower end of the piston rod 2, and a spring 4 is installed at the lower end of the connecting cylinder 3. A piston ball 5 is provided in the middle of the lower end of the spring 4. The piston rod 2 extends out of the upper end of the storage cylinder 1. A pressing connecting block 8 is inserted into the upper half of the outer side of the piston rod 2. An elastic contact block 9 is provided above the pressing connecting block 8 and is inserted into the piston rod 2. A support cylinder 7 is provided on the upper surface of the storage cylinder 1. A pressure block 10 is slidably provided in the middle of the support cylinder 7 and is inserted into the piston rod 2. A transmission rod 11 is slidably provided inside the support cylinder 7 and extends out of the upper end of the support cylinder 7. A second spring 15 is provided below the transmission rod 11, and the pressure block 10 is located below the pressing connecting block 8, while the transmission rod 11 is located below the elastic contact block 9.

[0026] When the pressure head 6 is pressed, the piston rod 2 initially presses the connecting barrel 3, causing the spring 4 to move downward and contract, and at the same time, the pressing connecting block 8 and the pressure block 10 are in extrusion contact, driving the multiple transmission rods 11 on the side to move downward synchronously, causing the second spring 15 to move downward and contract. When the pressure on the pressure head 6 is released, the spring 4 and the second spring 15 are stretched due to their own elasticity, causing the connecting barrel 3 and the elastic contact block 9 to stretch synchronously, causing the lower end of the piston rod 2 and the upper half of the outer side to be stretched by the elastic force, causing the piston rod 2 to rise quickly. Through the combined use of the multiple transmission rods 11 and the second spring 15, the elastic strength of the pressure head 6 when it rebounds is improved, effectively preventing the pressure head 6 from being limited in its return distance due to insufficient elasticity of the spring 4, thereby preventing blockage. By providing an elastic component on the upper end of the storage barrel 1, the device can be easily maintained and replaced from the outside, improving the convenience of use.

[0027] As shown in Figure 1 - Figure 4 The outer diameter of the pressing connecting block 8 is the same as that of the pressure block 10, the outer diameter of the elastic contact block 9 is the same as that of the support barrel 7, and the outer diameter of the pressing connecting block 8 is smaller than that of the elastic contact block 9. The pressure block 10 is located between the multiple transmission rods 11.

[0028] By pressing the pressing connecting block 8 and the pressure block 10, the pressing connecting block 8 and the pressure block 10 can be fully contacted, improving the pressing effect and ensuring uniform pressing and transmission of the outer transmission rod 11. The elastic contact block 9 and the support barrel 7 are in close contact, improving the uniformity of the multiple transmission rods 11 when they are in elastic contact with the elastic contact block 9, and ensuring stable and efficient pressing and resetting.

[0029] As shown in Figure 1 - Figure 4 The support barrel 7 has a plurality of guide grooves 14 on the inner wall, and the connecting plate 13 is slidably arranged in the guide grooves 14.

[0030] The connecting plate 13 extends to the middle of the side of the support barrel 7, and the transmission rod 11 is mounted on the upper end surface of the connecting plate 13.

[0031] Under the guidance and support of the guide grooves 14, and the double connection of the connecting plate 13 to the pressure block 10 and the transmission rod 11, the transmission rod 11 can move synchronously and accurately with the pressure block 10. Under the distance limitation of the guide grooves 14, the movement distance of the pressure block 10 and the transmission rod 11 can be limited, ensuring accurate and reliable movement during pressing and resetting.

[0032] Example two: an anti-clogging automatic rebound pump head, as shown in Figure 1 - Figure 4As shown, the second spring 15 is mounted on the lower end surface of the connecting plate 13, the lower end of the second spring 15 is provided with a guide barrel 16, and the second spring 15 is slidingly arranged in the guide barrel 16.

[0033] A telescopic rod is arranged in the middle of the guide barrel 16 and located in the middle of the second spring 15.
