The invention relates to air-soft guns and more particularly to an air-soft gun including a device for releasing remaining compressed air in the pistol-grip so that a subsequent release of compressed air from an air canister in a firing operation can be made easy.
Conventionally, compressed air may remain in a space between an air canister and an inner surface of a pistol-grip of an air-soft gun after firing. This has disadvantages of a great force being required to exert in a next firing, and increased probability of being hurt.
Thus, the need for improvement still exists.
It is therefore one object of the invention to provide an air-soft gun comprising a pistol-grip; a high-pressure air canister disposed in the pistol-grip; and a remaining compressed air release device comprising an externally threaded, cylindrical channel member threadedly secured to an end of the air canister and including an axial channel and a sealing ring; a rotatable cap releasably secured to the channel member; a biasing member fastened between the cap and the channel member and urging against the channel member; a striker including a needle on a first end, an internal passageway, an inlet proximate the needle and communicating with the passageway, an outlet proximate a second end and communicating with the passageway, internal threads on the passageway proximate the second end, and a threaded fastener driven through the cap into the internal threads to secure the cap to the striker; wherein the inlet is blocked by the sealing ring in an inoperative position of the remaining compressed air release device; and wherein a clockwise rotation of the cap causes the sealing ring to unblock the inlet, thereby flowing compressed air in the pistol-grip to the outlet through both the inlet and the passageway.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.

and a remaining compressed air release device 3 including an externally threaded, cylindrical channel member 4 threadedly secured to an end of the air canister 2 and including an axial channel 41 and a sealing ring 42; a rotatable cap 5 releasably secured to the cylindrical channel member 4; a compression spring 6 fastened between the cap 5 and the cylindrical channel member 4 and urging against the cylindrical channel member 4; a striker 7 including a needle 71 on a first end, an internal passageway 73, an inlet 72 proximate the needle 71 and communicating with the passageway 73, an outlet 74 proximate a second end and communicating with the passageway 73, internal threads 75 on the passageway 73 proximate the second end, and a screw 76 driven through the cap 5 into the internal threads 75 to secure the cap 5 to the striker 7. The inlet 72 is blocked by the sealing ring 42 in an inoperative position of the air-soft gun (see
