A firing device of airsoft gun includes, in combination a butt including a chamber, a passage, a front section, a sleeve member, a port at a front end of the sleeve member, a space in the chamber, a main disc at a rear end of the sleeve member, and a hole in a rear of the sleeve member communicating the sleeve member with the space; a firing mechanism including a sleeve, a stem in the sleeve and having a rear flange member, a disc in front of the sleeve, exit ports at the disc member, a flange member at a rear end of the stem, a flange in rear of the sleeve, and ports in rear of the stem; a valve; and a pressurized air canister in a rear end of the butt. A tunnel interconnects the air canister and a passage which communicate with the chamber. |

1. A firing device of an airsoft gun comprising, in combination:
a magazine (5) provided with a plurality of plastic pellets (50); a butt (1) including a chamber (10), a passage (11), a front section (12), a sleeve member (13), a port (14) at a front end of the sleeve member (13), an intermediate space (15) in the chamber (10), a main disc (16) at a rear end of the sleeve member (13), a hole (17) in a rear of the sleeve member (13) communicating the sleeve member (13) with the intermediate space (15), a tunnel (18), and a passageway (19); a firing mechanism (2) disposed at a joining portion of the chamber (10) and the magazine (5) and including a sleeve (21), a stem (22) in the sleeve (21) and having a rear flange member (26), a disc member (23) in a front of the sleeve (21) and releasably secured to a forward end (24) of the stem (22), a plurality of exit ports (25) at the disc member (23), a flange member (26) at a rear end of the stem (22), a flange element (27) in a rear of the sleeve (21) having an area greater than that of the flange member (26), a plurality of ports (28) in a rear of the stem (22), and a space member (29) disposed between the flange element (27) and the chamber (10); a valve (3) disposed adjacent to the sleeve (21) and communicating with the front section (12), the valve (3) including a moveable stem member (31); and a high pressure air canister (4) disposed in a rear end of the butt (1) and including a passage (40) communicating with the chamber (10) via an outlet (41), the high pressure air canister (4) communicating with the valve (3) via the passage (11); wherein the tunnel (18) is disposed between the passage (40) and the high pressure air canister (4) and communicates with both; wherein the passageway (19) is adjacent to the valve (3) and serves as a downstream of the valve (3); wherein in a pressurized air supplying operation the valve (3) is opened by pressurized air supplied from the high pressure air canister (4) via the passage (11), the firing mechanism (2) is activated by the pressurized air passing through the passageway (19) to move rearward to push the sleeve member (13) rearward, the main disc (16) is configured to stop the moving sleeve (21) from moving further rearward, a topmost one of the plastic pellet (50) is pushed to dispose at a front end of the chamber (10), a forward end (24) of the stem (22) blocks the port (14), and the pressurized air passes the hole (17) to flow back to the intermediate space (15); and wherein in a firing operation the valve (3) is closed to stop the pressurized air from flowing to the front section (12), the pressurized air pushes the firing mechanism (2) forward, the firing mechanism (2) moves forward to cause the flange member (26) to allow the pressurized air to flow out of the outlet (41), the pressurized air in the intermediate space (15) flows through a path between the sleeve member (13) and the stem (22) and further flows through the ports (28) to enter a space between the sleeve (21) and the stem (22), the pressurized air passes through the port (14) to enter the exit ports (25), and the pressurized air pushes the plastic pellet (50) at the front end of the chamber (10) out of the chamber (10) to fire. |
