Description

  The present invention relates to a toy gun air valve structure, and more particularly to a toy gun air valve structure that extends the service life and saves costs.

  Advances in science and technology have also increased the fidelity of toy guns, such as the ability to exchange magazines and the provision of backward reaction. Of these, many mechanisms (for example, magazines) need to be completed using the pressure of the high-pressure gas gas. In general, some air valves for assisting the filling of the gas gas use a spring to assist the sealing. In many cases, this assistance prevents the air valve from leaking. However, if the spring is used for a long time, fatigue occurs, the service life of the spring is shortened, and the cost is high even when the spring is replaced.

  The present invention mainly uses a pressure difference between the second air chamber and the intake passage to press the valve body, and selectively opens and closes the intake passage, so that the toy gun air valve has a long service life and can save costs. It is an object to provide a structure.

  With the above-described structure, when the high-pressure gas filling member is connected to the main body, high-pressure gas is introduced into the intake passage, and at this time, the air pressure in the intake passage is higher than the air pressure in the second air chamber. And the valve body is moved by pressing the intake pressure portion so that the communication between the intake passage and the first air chamber is not blocked, and the high pressure gas passes through the valve body passage and the through hole. The air enters the first air chamber, further enters the second air chamber from the first air chamber, and is injected into the space of the toy gun body.

  On the other hand, when the high-pressure gas filling member is not connected to the main body or when the high-pressure gas is not supplied, the air pressure in the second air chamber becomes higher than the air pressure in the intake passage, and the exhaust pressure And the valve body is moved to shut off the communication between the first air chamber and the intake passage. In this way, by controlling the valve body in place of the spring, there is no need to use the spring, so there is no problem of life due to the fatigue of the spring, and there is no need to install and replace the spring. The effect of saving can also be achieved.
