- 1. Field of the Invention
- The present invention relates generally to an emulsion squeeze head, and more particularly to an innovative squeeze head with a double-piston mechanism mounted onto the suction pipe of an actuating cylinder.
- 2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
- The emulsion squeeze head is structurally designed in a manner that the pumping action is implemented by the lifting and sliding action of a piston in an actuating cylinder. The pumping quality and service life of the emulsion squeeze head is closely related to wear and tear of the piston.
- In addition to the quality of the materials for the piston, the concentration of emulsion is also a crucial influential factor to the wear and tear of piston. As the emulsion with a higher concentration always contains fine articles, a close friction will occur between the sliding piston and the wall of the actuating cylinder, leading to possible wear and tear of the piston, failure of air-tightness, degraded pumping effect, poorer endurance and shorter service life of the emulsion squeeze head.
- Thus, to overcome the aforementioned problems of the prior art, it would be an advancement in the art to provide an improved structure that can significantly improve efficacy.
- Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
- There is enhanced efficacy of the present invention.
- Based on the present invention, the double-piston mechanism of the emulsion squeeze head is mainly composed of a first and a second piston. It is possible to improve the robustness and extend the life span of the piston mechanism of the emulsion squeeze head with better applicability.
- The improvements brought about by this invention are as follows:
- Based on the structure of the present invention, the first tube of the first piston and the second tube of the second piston can be set into different lengths. The first flange of the first piston and the second flange of the second piston are provided with space or without space, thus adapting itself to different suction spaces and strengths of the emulsion squeeze heads.
- Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.

-
FIGS. 1-3 depict preferred embodiments of a double-piston mechanism of the emulsion squeeze head of the present invention. The embodiments are not provided for only explanatory purposes with respect to the claims. - The emulsion squeeze head A comprises an actuating
syringe 10 and asuction pipe 20 in the actuatinggroove 11 of the actuatingsyringe 10. The top of thesuction pipe 20 is connected with apressing head 30, while an elastic resetter 40 (a spring) is arranged between the bottom of thesuction pipe 20 and the bottom wall of the actuatinggroove 11. Moreover, a stopper 50(a steel ball) is placed at the bottom of the actuatinggroove 11. Thesuction pipe 20 is also provided with apiston set 60. - The piston set includes a
first piston 61, including a first connectingportion 611 and afirst flange 612. The first connectingportion 611 is assembled onto thesuction pipe 20, and thefirst flange 612 is abutted on the wall of the actuatinggroove 11. The piston set also includes asecond piston 62, which is placed at one end of thefirst piston 61, including a second connectingportion 621 and asecond flange 622. The second connectingportion 621 is assembled onto thefirst piston 61, and thesecond flange 622 is abutted on the wall of the actuatinggroove 11. - Based on the aforementioned structures, the key design of the present invention is that the piston set 60 is a double-piston mechanism composed of
first piston 61 andsecond piston 62. When thesliding piston set 60 is lifted in the actuatinggroove 11 of the actuating syringe 10 (referring toFIG. 1 ), thefirst piston 61 andsecond piston 62 are air-sealed synchronously with the wall of the actuatinggroove 11. Meanwhile, the emulsion attached on the wall of the actuatinggroove 11 will be fully erased by the lowersecond piston 62. In such case, the possible tear and wear (high friction caused by dense emulsion) only occurs on thesecond flange 622 of thesecond piston 62, thereby maintaining the optimum air-tightness and pumping function. - Referring to
FIGS. 1-3 , thefirst piston 61 can be combined with thesecond piston 62, so that afirst tube 613 is formed at one end of the first connectingportion 611 of thefirst piston 61, and afirst groove 614 formed at the other end of the first connectingportion 611. Asecond tube 623 is formed at one end of the second connectingportion 621 of thesecond piston 62, and asecond groove 624 formed at the other end of the second connectingportion 621. Moreover, thefirst tube 613 can be inserted into thesecond groove 624, and thesecond tube 623 can be inserted into thefirst groove 614, enabling thefirst piston 61 to be mated with thesecond piston 62. - Furthermore, the
first tube 613 of thefirst piston 61 and thesecond tube 623 of thesecond piston 62 can be set into different lengths. Thefirst flange 612 of thefirst piston 61 and thesecond flange 622 of thesecond piston 62 are provided with space or without space. In this preferred embodiment, thefirst tube 613 of thefirst piston 61 is shorter than thesecond tube 623 of thesecond piston 62. Referring toFIGS. 2-3 , when thesecond piston 62 is assembled onto the bottom of thefirst piston 61, a space W1 will be formed between thefirst flange 612 of thefirst piston 61 and thesecond flange 622 of thesecond piston 62. Referring also toFIG. 4 , when thesecond piston 62 is assembled onto the top of thefirst piston 61, thefirst flange 612 of thefirst piston 61 is closely abutted with thesecond flange 622 of the second piston 62 (shown inFIG. 5 ). - The
first piston 61 andsecond piston 62 can also be prefabricated.
