When the variable container 200 is filled with the undiluted solution, the inner volume can be increased by expanding the vertical wrinkle 230 until it becomes circular as shown by the outline broken line in FIG. Also, as the undiluted solution of the variable container 200 is ejected, the inner volume of the vertical jar 230 may be reduced as shown by an inner dotted line in FIG. Accordingly, the flow of the variable container 200 in the pressure vessel 300 can be suppressed or prevented. In addition, the raw liquid filled in the variable container 200 can be discharged through the lateral wrinkles 220 or the vertical wrinkles 230.

In the pressure vessel 300, the variable vessel 200 is inserted. The pressure vessel 300 is filled with a compressed fluid.

The injection button 500 is formed with a communication groove portion communicating with the undiluted solution supply path portion 520 and the fluid supply path portion 530 from the outer circumferential surface of the injection button 500, Is formed to protrude. At least the source liquid supply path portion 520 among the source liquid supply path portion 520 and the fluid supply path portion 530 is connected to the stepped groove portion 510 or the stem path portion 72 along the discharge direction of the undiluted solution. As shown in FIG.

The injection port 600 is coupled to the injection button 500 and includes a spray hole 610 through which the undiluted solution is discharged. The injection port 600 may form a space communicating with the undiluted solution supply path portion 520. In addition, the injection hole 610 can mix and discharge the raw liquid and the compressed fluid. The injection port 600 communicates the undiluted solution supply path portion 520 and the fluid supply path portion 530 to form a space in which the undiluted solution and the compressed fluid are mixed. At this time, mixing projections 620 protrude from at least one of the jetting protrusion and the inner wall of the jetting port 600 to stir the stock solution or stir the stock solution and the compressed fluid.

The container fixing part 700 restricts the flow of the variable container 200 in the pressure container 300. The container fixing part 700 includes a container protrusion 710 protruded from one of the outer bottom of the variable container 200 and the inner bottom of the pressure container 300 and the container protrusion 710 And a container groove portion 720 formed in the other of the outer bottom of the variable container 200 and the inner bottom of the pressure container 300.

The protective cap 800 is detachably coupled to the inlet 310 of the pressure vessel 300. The protective cap 800 is connected to the mounting cup 400 exposed at the inlet 310 of the pressure vessel 300, the divide stem 70, the source solution stem 80, the injection button 500 ) And the jetting port (600).

Hereinafter, the operation of the fluid ejection apparatus according to one embodiment of the present invention will be described. The injection valve unit 100 is coupled to the variable container 200 with the end of the divide stem 70 being spaced apart from the end of the undiluted solution switch 60, The injection control valve unit 100 and the pressure vessel 300 are coupled to each other. The injection button 500 is coupled to an exposed portion of the divide stem 70. At this time, the variable container 200 is inserted into and supported by the pressure vessel 300 while the transverse wrinkle 220 is open, and the container protrusion 710 provided in the variable container 200 is pressurized by the pressure And is inserted into the container groove portion 720 provided in the container 300.

When the injection button 500 is pressed, the state of the first pressing step is reached. In the first step, the end of the divide stem (70) is brought into contact with the end of the stock solution switch (60). At this time, the sealing ring 102 surrounding the divide stem 70 maintains a state of being in close contact with the undiluted solution transfer path portion 11, and the undiluted solution switch 60 is in close contact with the hermetic portion 103 The switch guide 14 does not move. In addition, the stem gasket 90 is bent to communicate the fluid transmission path portion 12 and the fluid separation path portion 82.

Then, the undiluted solution transfer path part 11 is cut off along the switch guide 14, and the compressed fluid moved to the fluid transfer path part 12 flows through the fluid separation path part 82 and the fluid supply path 12, And is discharged to the injection port 600 through the nozzle 530. Accordingly, a space for mixing the undiluted solution and the compressed fluid can be cleanly secured at the injection port 600 side.

Subsequently, when the injection button 500 is further depressed, the state of the pushing step 2 is reached. In the second step, the source valve (60) is separated from the hermetic portion (103) by the divide stem (70). The sealing ring 102 wrapping the divide stem 70 is brought into close contact with the restriction jaw 17 to allow the undiluted solution delivery path portion 11 and the undiluted solution separation path portion 81 to communicate with each other. Further, the stem gasket 90 is further bent to maintain the fluid communication path portion 12 and the fluid separation path portion 82 in a connected state.

The internal volume of the variable container 200 is reduced due to the pressure applied to the variable container 200 by the compressed fluid in the pressure container 300. The width of the variable container 200 is reduced, The length of the variable container 200 can be prevented from varying and the variable container 200 can be held in the pressure container 300. [ In addition, since the flow of the variable container 200 is prevented, a gap is prevented from being generated between the variable container 200 and the variable housing 10 to allow the pressurized fluid to flow into the variable container 200 .

At this time, the vertical wrinkle portion 230 is also deformed to smoothly change the inner volume of the variable container 200, and to prevent the variable container 200 from being bent in the longitudinal direction. Also, the undiluted solution is moved toward the injection port 600 via the undiluted solution delivery path portion 11, the undiluted solution separation path portion 81, and the undiluted solution supply path portion 520. Then, the undiluted solution is stirred with the compressed fluid by the mixing protrusion 620, and is discharged as a mist through the injection hole 610. The sealing ring 102 wrapping the divide stem 70 is brought into close contact with the inner wall of the undiluted solution transport path part 11 and the limiting jaw part 17 when the injection button 500 is pressed in step 2, Thereby improving the sealing force of the undiluted solution delivery path portion 11 and restricting the movement of the divide stem 70.

On the other hand, when the pressing force of the injection button 500 is released, the pressing step is switched from the pressing step 2 to the pressing step 1. As a result, the undiluted solution delivery path portion 11 is shut off, and the compressed fluid is continuously discharged.

At this time, a relative negative pressure (vacuum) is generated in the undiluted solution separation path portion 81 and the undiluted solution supply path portion 520. Then, the undiluted solution transferred to the injection port 600 may flow back to the undiluted solution supply path portion 520, or the undiluted solution transferred to the injection port 600 may be discharged together with the compressed fluid. Further, the undiluted solution remaining in the undiluted solution supply path portion 520 flows back at least toward the undiluted solution separation path portion 81 side. Due to the backflow phenomenon and discharge, it is possible to prevent or prevent the undiluted solution from remaining at least at the injection port 600, thereby preventing the droplet of the undiluted solution from being formed in the injection hole 610.

In other words, when the pressurization fluid is transferred through the fluid supply path portion 530 and discharged through the injection hole 610, the compressed fluid remains in the undiluted solution supply path portion 520, The undiluted solution and at least the undiluted solution transferred to the injection opening 600 among the undiluted solution transferred to the injection opening 600 are discharged together with the compressed fluid according to the Bernoulli principle. By virtue of this Bernoulli principle, droplet formation of the undiluted solution in the injection hole 610 is prevented.

When the pushing force of the injection button 500 is completely released, the initial state is established, and the stem gasket 90 returns to its original position and closes the opening / closing hole 76.

According to the above-described fluid ejection apparatus, even if the variable container 200 is deformed by pressure, it is possible to prevent the variable container 200 from shaking in the pressure container 300, Can be prevented from flowing. In addition, it is possible to improve the uprightness of the variable container 200 and suppress or prevent the flexible container 200 from being bent. In addition, when the pressure vessel 300 is shaken, it is possible to suppress or prevent noise from being generated in the pressure vessel 300, to suppress or prevent the bottom of the variable vessel 200 from flowing in the initial position, Even if the variable container 200 swings, the bottom of the variable container 200 can be naturally returned to the initial position.

Further, it is possible to provide a strong jetting force to the raw liquid filled in the variable vessel 200 through the detailed structure of the fluid injecting apparatus, and to stabilize the original liquid in accordance with the pressing event even when the variable vessel 200 is in the reverse position or lying down Can be sprayed. In addition, the raw liquid and the compressed fluid are separated and stored, and as the raw liquid and the compressed fluid are mixed in the injection port 600, the raw liquid having a high viscosity can be sprayed in a mist form. In addition, since only the undiluted solution is filled in the variable container 200 in a sealed state without any external contact, deterioration or denaturation of the undiluted solution can be prevented.

In addition, it is possible to prevent leakage of the undiluted solution in the injection hole 610 and to prevent the undiluted solution from solidifying in the injection hole 600 or the injection hole 610.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Modify or modify the Software.
