Problems solved by technology

[0004] 1. The traditional tear gas injector is for one-time use, which leads to a large waste of materials and high cost of use;
[0005] 2. Existing refilling tear gas injectors need external equipment, such as air pumps, when infusing high-pressure gas
[0006] 3. Even if it is a refillable tear gas injector, in the storage state, the gas is always in a compressed state in the tank, and its sealing performance cannot ensure that the gas in the tank will not leak in a long-term high-pressure environment, which will affect the safety of emergency situations. use
