In figure: volume body 1, upper cover 2, bottom 3, pressure lever mechanism 4, air inlet storehouse 5, containing liquid chamber 6, cavity 7, hollow depression bar 8, liquid outlet 9, a check valve 10, piston 11, No. two pistons 12, No. two check valves 13, elastic component 14, extension spring 15, a seal ring 16, No. two seal rings 17, induction opening 18.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
Embodiment.
See Fig. 1, the extrusion equipment of the present embodiment mainly comprises volume body 1, upper cover 2, bottom 3, pressure lever mechanism 4, air inlet storehouse 5, containing liquid chamber 6, No. two pistons 12, No. two check valves 13 and elastic component 14.
Upper cover 2 in the present embodiment is connected with the oral area of volume body 1, bottom 2 is connected to the bottom of volume body 1, pressure lever mechanism 4 comprises hollow depression bar 8, liquid outlet 9 and a check valve 10, hollow depression bar 8 is connected with a check valve 10, liquid outlet 9 and this check valve 10 is communicated with, liquid outlet 9 is above vessel, and a check valve 10 has the function of only export but no import, thus reaches the effect that extraneous air can not be back to volume body 1.
A piston 11 in the present embodiment and No. two pistons 12 are all arranged in volume body 1, a piston 11 contacts with elastic component 14, there are No. two check valves 13 below of a piston 11, a piston 11 is connected with hollow depression bar 8, a piston 11 there is the seal ring 16 mated with it, No. two pistons 12 there are No. two seal rings 17 mated with it, bottom 2 has induction opening 18, air inlet storehouse 5 is formed between bottom 2 and No. two pistons 12, containing liquid chamber 6 is formed between No. two pistons 12 and No. two check valves 13, cavity 7 is formed between a piston 11 and No. two check valves 13, hollow depression bar 8 is connected with a piston 11 through after upper cover 2.
One end of elastic component 14 in the present embodiment contacts with a piston 11, the other end of this elastic component 14 contacts with upper cover 2, and the upper end of a piston 11 is connected with the lower end of hollow depression bar 8, and elastic component 14 adopts extension spring 15, also the structures such as spring can be adopted, as long as this effect can be reached.
During use, the hollow depression bar 8 in pressure lever mechanism 4 is pressed with hand, hollow depression bar 8 drives a piston 11 down to move, the volume of the cavity 7 of sealing is diminished, pressure increase, simultaneously the bottom of cavity 7 is provided with No. two check valves 13 of only import but no export, and the air therefore under the effect of the pressure in cavity 7 or liquid can flow out along hollow depression bar 8 from a check valve 10, due to the setting of a check valve 10, the air flowed out from a check valve 10 or liquid cannot be back in cavity 7; Hand unclamps depression bar 9, under the effect of extension spring 15, a piston 11 slowly rises, and makes the volume of the cavity 7 of sealing become large, pressure reduces, pressure in cavity 7 is less than the pressure in containing liquid chamber 6 and air inlet storehouse 5, thus the liquid 7 of containing liquid chamber flows into cavity 7 by No. two check valves 13, and the pressure of containing liquid chamber 6 has the trend of reduction simultaneously, under atmospheric pressure, promote No. two piston 12 upward movements, make cavity 7, containing liquid chamber 6 and air inlet storehouse 5 three reach dynamical equilibrium, once extruded; Extruding repeats above-mentioned steps again.
Pressure lever mechanism 4 in the present embodiment can according to different purposes, be designed to different shapes and size etc., can control the liquid outlet quantity of each pressing, the liquid at every turn extruding several milliliters is all feasible, the most applicable liquid drug, cosmetics, shower cream etc., little crowded amount very easy to use.
The mode of the present embodiment just citing wherein a kind of direct promotion piston 11, also can adopt the modes such as electronic, air pressure to realize, all belong to protection scope of the present invention.
By above-mentioned elaboration, those skilled in the art can implement.
In addition, it should be noted that, the specific embodiment described in this specification sheets, the shape, institute's title of being named etc. of its parts and components can be different, and the above content described in this specification sheets is only to structure example of the present invention explanation.The equivalence change that structure, feature and the principle of all foundations described in inventional idea of the present invention are done or simple change, be included in the protection domain of patent of the present invention.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment; only otherwise depart from structure of the present invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
