Piston structure of toy gun
A piston structure of a toy gun is disclosed. An air induction passage and at least an air inlet are formed on the piston. In addition, a control device is applied to the piston for correspondingly opening or closing the air inlet according to the movement of the piston. As a result, much more air can be sucked into an air storage chamber immediately after the backward movement of the piston. Therefore, the air capacity of the air storage chamber of the cylinder tube can be increased so as to produce larger air pressure for pushing the bullet to the outside of the toy gun, thereby simulating the recoil effect of the real shooting and improving the shooting performance of the toy gun.

The present invention relates to a piston structure of a toy gun, and more particularly to a toy gun with increased air suction area and air suction speed so as to produce larger air pressure for pushing the bullet away from the toy gun.
BACKGROUND OF THE INVENTIONThe conventional toy gun includes a cylinder tube embedded securely in a gun body, wherein a rack is mounted on the bottom of the piston extending to the outside of the cylinder tube for driving the piston by a gear set. The gear set includes a driving gear, a steering gear and a final gear, wherein the final gear is a semi-gear with an incomplete gear ring, whereby the air can be compressed and exhausted by disengaging a releasing arc edge of the final gear from the rack after backward driving the rack and the piston by the final gear.
Due to the fast movement of the piston in the air suction process, the amount of air sucked into the cylinder tube via the gun muzzle is insufficient. As a result, the shooting performance of the toy gun is reduced.
SUMMARY OF THE INVENTIONIt is a main object of the present invention to provide a piston structure of a toy gun, wherein an air induction passage and at least an air inlet are formed on the piston for increasing the area of air suction such that much more outside air can be sucked into the air storage chamber immediately after the backward movement of the piston. As a result, the air capacity of the cylinder tube can be increased so as to produce larger air pressure for pushing the bullet away from the toy gun, thereby providing the simulated recoil effect, which simulates the real shooting, and improving the shooting performance of the toy gun.
Referring to
In order to improve the shooting performance of the toy gun for simulating the recoil effect of real shooting, much more air must be accumulated in the cylinder tube so as to produce larger air pressure for pushing the bullet away from the toy gun. In order to inhale much more air rapidly and improve the efficiency of air suction, the present invention is characterized in that an air induction passage and at least an air inlet are formed on the piston for increasing the air suction area, and that a control device is applied to the air inlet for correspondingly opening or closing the air inlet according to the forward or backward movement of the piston. Therefore, in the air suction state, the air suction amount and the air capacity of the cylinder tube can be increased. Besides, in the shooting state, the air inlet is closed by the control device so as to produce larger air pressure for pushing the bullet to the outside of the toy gun.
