The present invention pistol-type gas injector according to the drawings consists of a gas injector main body 100 and a nozzle bundle 200.

The water spraying machine main body 100 includes a barrel 120 in which a compressed gas chamber 112 is formed on the gripper 110 side, and a passage 122 through which the compressed gas is discharged above the gripper 110 is formed. Other constructions such as bursting gunpowder are omitted.

The nozzle bundle 200 forms a blowout groove 226 which is circumferentially circumferentially communicating with the upper portion of the compressed gas chamber 112, and communicates with the central passage 222 in the horizontal direction, and in the central passage 222. A communication hole 224 is formed and the nozzle pin 210 is slidably inserted into the trigger 130 at the front, and the pressure drop is pressed by the nozzle pin 210 at the rear of the center passage 222. 231, the chamber 230a in which the coil spring 234 is wound, and the housing 230 forming the inlet hole 232 through which the compressed gas flows are coupled to the gas in the compressed gas chamber 112. To be fired along 122.

More specifically, the launching means 200 forms a central passage 222 through which the nozzle pin 210 is inserted / guided, and forms a communication hole 224 to the outside, but the ejection groove portion is formed around the outside of the communication hole 224. It is preferable to make the nozzle bundle 220 having the 226 formed thereon long and detachable.

The nozzle bundle 220 is a sealing member 223 is coupled to the inner center passage 222 and the outer front, rear surface to block the leakage of the gap.

In particular, the nozzle bundle 220 and the chamber 230 are fitted with a screw 235, the screw is also formed correspondingly to the rear end of the nozzle bundle 200.

The pressure drop 231 forms an inserting portion 231a and a mounting groove 231b, and is separated into a rubber cap 233 inserted into the mounting groove 231b.

The nozzle pin 210 forms an inlet hole 212 and an outlet hole 213 in the center of the body, but a space 211 is provided therein, and the front end side of the body forms a wide diameter rim 214 but contacts the trigger. To form a contact surface 215.

6A and 6B are cross-sectional views of a pistol-type gas injector according to the present invention.

The action of the gas injector of the present invention according to the drawing is that the compressed gas in the gripping portion 110 is released by pulling the trigger 130.

That is, the nozzle pin 210 is moved backwards along the center passage 222 as the nozzle pin 210 contact surface 215 of the grip portion 110 is pressed by the trigger 130, so that the center passage 222 is pulled. The inner coil spring 234 and the suppressor 231 of the housing 230 coupled to the rear end are suppressed.

Since the compressed gas flows into the chamber 230a through the inlet hole 232 before the backward movement of the pressure drop 231 and is filled in the chamber 230a, when the pressure drop 231 moves, the inflow of the nozzle pin 210 flows in. Since the ball 212 is located in the chamber 230a, the compressed gas is instantaneously introduced.

At the same time, the compressed gas introduced into the inlet hole 212 is moved to the outlet hole 213 side while the high pressure compressed gas is spouted into the communication hole 224 of the nozzle bunch 220 communicating with the ejection groove 226. Riding along the passage 122 extending to the barrel 120 is to be launched with a strong compression force.

Compressed gas is continuously injected while the trigger 130 is pulled, and the release of the compressed gas is stopped when the trigger 130 is released.

The present invention forms a communication hole 224 to the outside, but the nozzle bundle 220 formed by injecting the ejection groove 226 to the outside of the communication hole 224 is formed or easily mounted in the holding unit 110 The detachable structure has a simple structural advantage assembling as compared to the conventional gripping portion 110 as a whole triggered.

In addition, the pressure-sensitive opening 231 of the housing 230 of the present invention forms the inserting portion 231a and the mounting groove 231b, so that the rubber cap 233 inserted into the mounting groove 231b can be assembled / removed. When contact wear due to contact with the pin 210, the rubber cap 233 can be replaced, so the rubber cap at the end of its life can be replaced.

As described above, the pistol-type gas injector according to the present invention operates as a compressed gas chamber, a firing means, and a nozzle pin as a trigger to inject compressed gas into the main body, thereby injecting compressed gas, and thus, a conventional gas injection machine of a chemical injection type. This provides a significantly improved gas injector compared to their pistol structure.

The present invention provides a trigger / nozzle structure in which the holding part of the pistol is a compressed gas chamber as a gas injector closest to the pistol type, and the pressurized gas of the compressed gas chamber is opened and closed through an upper trigger of the compressed gas chamber. In the prefabricated structure of the detachable nozzle bundle, a pressure suppression structure required for inflow of the compressed gas is further provided, thereby providing a pistol-type gas injector having an improved power output.

The present invention has the effect of providing a prefabricated gas injector in which the nozzle / pressure structure for ejecting the compressed gas is assembled and at the same time easy to install, detach.
