There is a discharge valve 71 on circumferential surface, there is a conduit 72 in the bottom of piston 7, communicate therewith to be arranged in the cylinder 1；
Finally, the upperpush rod 6 correspondence one pressure head 8 of connection and communicate therewith, the pressure head 8 is hollow form, the pressure head 8 stretches out a nozzle
81, there is an adapter 82 in the bottom of pressure head 8, the inner ring surface of the adapter 82 is provided with the second snap ring 83, to upperpush rod 6
The clamping of first snap ring 63, the piston 7 is coated on wherein；It is as shown in Figure 3 that its combination completes figure.
Fig. 4 A～Fig. 4 C are referred to, is the continuous diagram of the operation chart of the present invention.As shown in Figure 4 A, in start pressing
After the pressure head 8 is moved down, upperpush rod 6 is now driven to move down to S1 regions in icon, while the piston portion of piston rod 3
31 by the internal face of cylinder 1 friction effects and transfixion, now make the outlet valve of the piston 7 because pressure head 8 is moved down
Door 71 is gradually connected with the nozzle 81, and works as the pressure head 8 and be moved to behind Sl regions and can offset with the top of piston 7, goes out this
Material valve 71 oneself completely to should nozzle 81, now because the lid 21 of pressure dependence check (non-return) valve 2 can downwards close the pan feeding port
17；Such as Fig. 4 B, then after the pressure head 8 enters S2 regions, the pressure head 8 drives upperpush rod 6 to press the spring 34, until upperpush rod
6 internal screw thread 62 is butted on after the locking closure thread 54 of the locking closure 5, and the air inside cylinder 1 is because of the piston portion 31 of piston rod 3
Extrude the space of cylinder 1 and derived by nozzle 81, it is related that derived liquid will be wanted also to derive from the nozzle 81；As Fig. 4 C and work as
When the pressure head 8 is intended to be resetted, the upperpush rod 6 is subject to the elastic force of spring 34 to push against upwards, and the piston portion 31 of the piston rod 3 is received
The internal face frictional force transfixion of cylinder 1, after the pressure head 8 is continued up with upperpush rod 6, the piston rod of the upperpush rod 6 hooks 61
The upper terminal block rank 33 of piston rod 3 is propped up, and drives piston rod 3 together upwards, while the upperpush rod 6 closes the piston 7
Discharge valve 71, finally the lower terminal block rank 32 of the piston rod 3 offset with the limit rank 53 of the locking closure 5 and stop, it is multiple to complete
Position；At the same time, the space increase of cylinder 1, therefore liquid pushes lid open because pressurized relation flows into storage tank 16 via perforation 151
21, pan feeding port 17 is gradually opened, make liquid enter cylinder 1 via check (non-return) valve 2, it is that next stock is prepared.
In addition when the pressure head 8 is resetted, now the discharge valve 71 is gradually closed, the pressure of the inner space of pressure head 8
Gradually increase, cause generation pull of vacuum, produce back the liquid stayed in inside nozzle 81 and be taken as using, prevent whereby in nozzle 81
The liquid in portion is affected to flow out by centrifugal force.
Fig. 5 is referred to, is the continuous diagram of another operation chart of the present invention.As illustrated, the vapour-pressure type of the present invention
Ejecting device also has locking, leakproof and blocking function.As shown in figure 5, press the pressure head 8 down moving by the Sl and S2 areas
Behind domain, and the pressure head 8 that turns clockwise makes the internal screw thread 62 of the inner peripheral surface of upperpush rod 6 and the locking closure thread of locking closure 5 to the S3 regions
54 screw locking, and now the check (non-return) valve 2 is extruded by piston rod 3, and the storage tank 16 for making the cylinder 1 is become by the elastomer 223
Shape is simultaneously filled and forms sealing state, to prevent liquid from oozing out.
Fig. 6 A～Fig. 6 C are referred to, is another embodiment of the present invention structure sectional view.Elasticity on the check (non-return) valve 2
In addition to previous embodiment is toroidal, the elastomer 223 also may be designed as > shapes as shown in Figure 6A to body 223, as shown in Figure 6B
Semicircle, or the squared design shown in Fig. 6 C；In addition, referring to the another example structure sectional view of Fig. 7, the aforementioned piston
Piston portion 31 on one end of connecting rod 3 is integrally formed with the piston rod 3, also may be designed as the button of piston portion 31 located at the piston
On the one end of connecting rod 3.
Only embodiments described above, be for preferably embodiment, when the scope of the present invention can not be limited with this,
If the equivalence changes made according to scope of the present invention patent and description or modification, should all belong to the following patent of the present invention
Covering scope.
