There are not only ammunition consumptions but also problems with the wear and tear of the firearms themselves. Especially in the field of national defense education, live ammunition not only has high training costs but also safety risks, as well as a series of problems such as the purchase, transportation, and management of firearms and ammunition.

[0003] Under this background, laser training systems powered by electricity or compressed gas have been widely used. However, whether driven by electricity or compressed gas, the simulation effects in terms of sound, light, heat, and recoil are far from reaching the level of real firearms, which greatly reduces the simulation effect during actual training. To solve this problem, we have invented a recoil simulation system powered by gas. Summary of the Invention

[0022] As a preferred technical solution of the present invention: The combustible gas includes one of butane, propane, natural gas, and hydrogen.

[0023] A method for using a gas-powered recoil simulation system, characterized by comprising the following steps: S1. Initial stage In the initial state, there is no combustible gas in the gas-powered launcher. After the combustible gas in the gas cylinder enters the rear-end channel and the first connection channel of the metering valve seat through the gas supply pipe, it is blocked by the metering valve core. When the recoil slider is pulled backward to compress the recoil spring, at this time, the metering valve core moves backward in the stroke channel under the action of the metering valve return spring. When it moves to a preset position, the second connection channel and the third connection channel can be made to communicate. At this time, the gas supply pipe installed in the rear-end channel inputs the combustible gas into the gas transportation channel formed by the metering valve core and the metering valve cap through the second connection channel and the third connection channel. When the recoil slider is released, the recoil spring drives the recoil slider to accelerate forward and impact the metering valve cap. The metering valve core and the metering valve cap move forward to the initial position. At this time, the first connection channel and the third connection channel communicate, the metering valve core seals the second connection channel, and the combustible gas in the gas transportation channel enters the front-end channel through the third connection channel and the first connection channel. The combustible gas conduit installed in the front-end channel transports the combustible gas to the gas-powered generator, completing the state of being ready to fire; S2. Combustion and work stage S21. Adjust the mode knob to select the single-shot mode. After pulling the trigger, the firing mode control board generates an ignition signal. At this time, after receiving the ignition signal, the ignition control board controls the battery to charge the capacitor. After the charging is completed, the ignition control board controls the high-voltage ignition voltage component of the capacitor to generate an arc in the gas power generator, igniting the combustible gas inside. The gas power generator pushes the recoil slider backward. The recoil slider compresses the recoil spring and impacts the housing to generate a recoil force. The metering valve core moves backward under the action of the metering valve return spring, and the combustible gas enters the gas delivery channel formed by the metering valve core and the metering valve cap from the rear of the metering valve core. S22. Adjust the mode knob to select the burst mode. After pulling the trigger, the firing mode control board continuously emits ignition pulse signals. At this time, after receiving the ignition signal, the ignition control board controls the battery to continuously charge the capacitor. The ignition control board then controls the high-voltage ignition voltage component of the capacitor to continuously generate an arc in the gas power generator. Once the recoil slider impacts the metering valve assembly, combustible gas will enter the gas power generator. At this time, the combustible gas can be ignited. Keep pulling the trigger, and continuous shooting will occur until the combustible gas in the gas cylinder is exhausted. S23. Adjust the mode knob to select the safety mode. At this time, the firing mode control board is short-circuited, and no ignition signal can be generated even if the trigger is pulled. The ignition control board does not receive the ignition signal and will not perform ignition and firing. S3. Reset stage After completing the ignition and firing, after the recoil slider impacts the housing, the recoil spring drives the recoil slider to accelerate forward and impact the metering valve cap. The metering valve core and the metering valve cap move forward, opening the front channel of the metering valve seat and closing the rear channel, allowing the combustible gas to enter the gas power generator through the combustible gas conduit to complete the cocked state. Pulling the trigger again can complete the next firing.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention can utilize combustible gases such as propane, butane, and hydrogen to burn to generate power, simulating the recoil force generated during the firing process of automatic firearms, automatic guns, etc., enabling users to have a more realistic experience during national defense education and training. Moreover, it has a low production cost, is easy to use, has a simple operation, and a low safety risk, and is very worthy of popularization and use. Description of the drawings

The combustible gas in the gas cylinder (5-3) enters the rear end channel (3-13) and the first connecting channel (3-10) of the quantitative valve seat (3-4) through the gas supply pipe (5-1), and is blocked by the quantitative valve core (3-3). When the recoil slider (4-1) is pulled backward to compress the return spring (4-3), the quantitative valve core (3-3) moves backward in the stroke channel (3-9) under the action of the quantitative valve return spring (3-5). When it moves to a preset position, the second connecting channel (3-11) and the third connecting channel (3-15) are connected. At this time, the gas supply pipe (5-1) installed in the rear end channel (3-13) inputs the combustible gas from the second connecting channel (3-11) and the third connecting channel (3-15) to the quantitative valve core. (3-3) and the quantitative valve cap (3-6), when the recoil slider (4-1) is released, the recoil slider (4-1) is driven by the recoil spring (4-3) to accelerate forward movement and hit the quantitative valve cap (3-6), the quantitative valve core (3-3) and the quantitative valve cap (3-6) move forward to the initial position, at which time the first connecting channel (3-10) and the third connecting channel (3-15) are connected, the quantitative valve core (3-3) seals the second connecting channel (3-11), the combustible gas in the gas delivery channel (3-14) enters the front channel (3-12) through the third connecting channel (3-15) and the first connecting channel (3-10), and the combustible gas conduit (3-1) installed in the front channel (3-12) conveys the combustible gas to the gas power generator (2), completing the standby state; S2, combustion and work stage; S21, adjust the mode knob (6-2) to select the single-shot mode, and after pulling the trigger (6-1), the firing mode control board (6-3) generates an ignition signal. At this time, after receiving the ignition signal, the ignition control board (6-4) controls the battery (6-6) to charge the capacitor (6-5). After the charging is completed, the ignition control board (6-4) controls the high-voltage ignition voltage element of the capacitor (6-5) to generate an arc in the gas-powered generator (2), thereby igniting the combustible gas inside the gas-powered generator (2). The gas-powered generator (2) pushes the recoil slider (4-1) to move backward, and the recoil slider (4-1) compresses the return spring (4-3) and hits the housing (1) to generate recoil force. The quantitative valve core (3-3) moves backward under the action of the quantitative valve return spring (3-5), and the combustible gas enters the gas delivery channel (3-14) formed by the quantitative valve core (3-3) and the quantitative valve cap (3-6) from the rear of the quantitative valve core (3-3).
