[0041] Please refer to the following for details. Figures 1-4 The non-metallic spring includes a first support body, a second support body, a first helical body 4, a second helical body 5, a connector 3, a first connecting body 6, and a second connecting body 7. Specifically, the first and second support bodies are annular structures, with the second support body positioned opposite to the first support body; the first helical body 4 and the second helical body 5 are spiral "U" shaped structures, with two first helical bodies 4 and two second helical bodies 5 respectively positioned between the first and second support bodies, and their ends connected to the first and second support bodies respectively; the connector 3 is a hollow cylindrical structure, connected to and communicating with the first support body, and has a connecting part 301 on its outer wall; the first connecting body 6 and the second connecting body 7 are arc-shaped structures, with their ends connected to the middle positions of the first helical body 4 and the second helical body 5 respectively.

[0042] In this embodiment, the connecting part 301 is a raised rib arranged around the outer wall of the connector 3, which can match the annular groove on the emulsion pump valve core 8. That is, the metal-free spring can be fixed to the emulsion pump valve core 8 through the snap-fit ​​engagement of the connecting part 301 and the annular groove. In actual use, it works with the emulsion pump to realize the function of repeatedly pressing the emulsion pump to extract liquid, and can ensure that the metal-free spring will not separate from the emulsion pump valve core 8 and will not shake, thereby improving the stability of the emulsion pump during operation and ensuring the pumping efficiency.

[0043] In this embodiment, the first support and the second support have the same specifications.

[0044] In the embodiment, the diameter of the connecting head 3 is smaller than the diameter of the first support body 1 or the second support body 2.

[0045] Further, the thickness ratio of the first connecting body 6 and the second connecting body 7 to the first support body or the second support body is 1:2.4, that is, the thickness of the first connecting body 6 and the second connecting body 7 is only two fourths of the thickness of the first support body or the second support body. The thickness of the first connecting body 6 and the second connecting body 7 is made smaller, so that the spiral body can be compressed more limitedly (the spiral body can be compressed more flatly), the force provided by the spring during the spring return is improved, and the discharging is more efficient.

[0046] Further, the first support body or the second support body is provided with a limiting portion 101. When the non-metallic spring is fixed with the emulsion pump valve core 8, the limiting portion 101 can limit the position of the non-metallic spring, and prevent the occurrence of the condition that the non-metallic spring is excessively installed.

[0047] Further, the first connecting body 6 and the second connecting body 7 are respectively inclinedly connected between the first spiral body 4 and the second spiral body 5. The first connecting body 6 and the second connecting body 7 connect the middle positions of the first spiral body 4 and the second spiral body 5, strengthen the strength of the spiral body, and prolong the service life of the non-metallic spring.

[0048] Further, the first support body 1, the second support body 2, the first spiral body 4, the second spiral body 5, the connecting head 3, the first connecting body 6 and the second connecting body 7 are of an integrated structure, and are integrally injection molded.
