BACKGROUND OF THE INVENTION
[0005] 1. Field of the Invention
[0006] 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.
[0007] 2. Description of Related Art Including Information
Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 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.
BRIEF SUMMARY OF THE INVENTION
[0012] There is enhanced efficacy of the present invention.
[0013] 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.
[0014] The improvements brought about by this invention are as
follows:
[0015] 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.
[0016] 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.

DETAILED DESCRIPTION OF THE INVENTION
[0022] The features and the advantages of the present invention
will be more readily understood upon a thoughtful deliberation of
the following detailed description of a preferred embodiment of the
present invention with reference to the accompanying drawings.
[0023] 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.
[0024] The emulsion squeeze head A comprises an actuating syringe
10 and a suction pipe 20 in the actuating groove 11 of the
actuating syringe 10. The top of the suction pipe 20 is connected
with a pressing head 30, while an elastic resetter 40 (a spring) is
arranged between the bottom of the suction pipe 20 and the bottom
wall of the actuating groove 11. Moreover, a stopper 50(a steel
ball) is placed at the bottom of the actuating groove 11. The
suction pipe 20 is also provided with a piston set 60.
[0025] The piston set includes a first piston 61, including a first
connecting portion 611 and a first flange 612. The first connecting
portion 611 is assembled onto the suction pipe 20, and the first
flange 612 is abutted on the wall of the actuating groove 11. The
piston set also includes a second piston 62, which is placed at one
end of the first piston 61, including a second connecting portion
621 and a second flange 622. The second connecting portion 621 is
assembled onto the first piston 61, and the second flange 622 is
abutted on the wall of the actuating groove 11.
[0026] 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 and second piston 62. When
the sliding piston set 60 is lifted in the actuating groove 11 of
the actuating syringe 10 (referring to FIG. 1), the first piston 61
and second piston 62 are air-sealed synchronously with the wall of
the actuating groove 11. Meanwhile, the emulsion attached on the
wall of the actuating groove 11 will be fully erased by the lower
second piston 62. In such case, the possible tear and wear (high
friction caused by dense emulsion) only occurs on the second flange
622 of the second piston 62, thereby maintaining the optimum
air-tightness and pumping function.
[0027] Referring to FIGS. 1-3, the first piston 61 can be combined
with the second piston 62, so that a first tube 613 is formed at
one end of the first connecting portion 611 of the first piston 61,
and a first groove 614 formed at the other end of the first
connecting portion 611. A second tube 623 is formed at one end of
the second connecting portion 621 of the second piston 62, and a
second groove 624 formed at the other end of the second connecting
portion 621. Moreover, the first tube 613 can be inserted into the
second groove 624, and the second tube 623 can be inserted into the
first groove 614, enabling the first piston 61 to be mated with the
second piston 62.
[0028] Furthermore, the first tube 613 of the first piston 61 and
the second tube 623 of the second piston 62 can be set into
different lengths. The first flange 612 of the first piston 61 and
the second flange 622 of the second piston 62 are provided with
space or without space. In this preferred embodiment, the first
tube 613 of the first piston 61 is shorter than the second tube 623
of the second piston 62. Referring to FIGS. 2-3, when the second
piston 62 is assembled onto the bottom of the first piston 61, a
space W1 will be formed between the first flange 612 of the first
piston 61 and the second flange 622 of the second piston 62.
Referring also to FIG. 4, when the second piston 62 is assembled
onto the top of the first piston 61, the first flange 612 of the
first piston 61 is closely abutted with the second flange 622 of
the second piston 62 (shown in FIG. 5).
[0029] The first piston 61 and second piston 62 can also be
prefabricated.
