Cylinder tube of toy gun
A cylinder tube of a toy gun is disclosed. A cylinder head is mounted on the cylinder tube of the toy gun. A tube passage is formed to penetrate through the cylinder head. Several air induction passages are formed circularly around the tube passage. A control device is applied to the air induction passages for opening or closing the air induction passages according to the forward or backward movement of the piston. As a result, much more air can be sucked into the air storage chamber immediately after the backward movement of the piston. Accordingly, the air capacity 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 improving the shooting performance of the toy gun and providing the simulated recoil effect, which simulates the real shooting.

The present invention relates to a cylinder tube 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.
The air capacity of the cylinder tube is affected by the size of the gun body. Besides, the air suction ability of the cylinder tube is also affected by the size of the gun body. Due to the fast movement of the piston in the air suction process, the amount of air sucked into the cylinder tube via the tube passage of the cylinder head is insufficient. As a result, the shooting performance of the toy gun is reduced.
SUMMARY OF THE INVENTIONWhereas the foregoing description, the present inventor makes diligent studies in providing an improved structure so as to overcome the conventional problems.
It is a main object of the present invention to provide a cylinder tube of a toy gun, wherein air induction passages are formed circularly on a cylinder head 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.
