When the face of a specific person being sprayed is sprayed, the slow shooting speed and short spray distance make it easy for the person being sprayed to avoid the shot and not hit the face, which greatly affects the law enforcement effect, and the criminal suspect cannot be quickly and effectively controlled. Therefore, the initial speed of the single police equipment for spraying tear gas will be compulsorily regulated to be 90 to 180 meters per second. According to the requirements of the single police equipment for spraying tear gas to be issued by the public security department, the high-pressure spring 5 is used as the power. The utility model adopts a special fastener which can withstand a large pressure instantaneously, and the special fastener is the locking tab 6. When the driving motor 13 and the cam 14 are started, the locking tab 6 is driven to be separated.

[0043] The lower part of the locking piece 6 is provided with a through hole and exposed outside through the sleeve 3, the switch unit comprises a battery 12, a driving switch and a driving motor 13 connected in sequence, the driving switch is used for controlling the start and stop of the driving motor 13, the driving motor 13 is drivingly connected with a cam 14, the cam 14 is matched with the lower part of the locking piece 6, when the driving motor 13 controls the rotation of the cam 14, the cam 14 abuts against the locking piece 6, so that the locking piece 6 is separated from the annular clamping groove 11. The existing police configuration hand-held tear gas sprayer is gas-powered, because the gas pressure is low, the initial velocity of the spray is only about 3 meters per second, and the spray distance is not more than five meters. When the face of a specific person is sprayed with tear gas, because the shooting speed is slow and the spray distance is not far, the person being sprayed can easily avoid the shot and not hit the face, which greatly affects the law enforcement effect and cannot quickly and effectively control the criminal suspect. Therefore, the initial velocity of the single police tear gas sprayer equipment to be introduced by the public security department is forced to be 90-180 meters per second. According to the requirements of the single police tear gas sprayer equipment to be introduced, the high-pressure spring 5 is used as the power. The utility model adopts a special fastener which can instantly bear a large pressure, and the special fastener is the locking piece 6. When the driving motor 13 and the cam 14 are started, the locking piece 6 is moved to be separated. When the high-pressure spring 5 is instantly released to generate a large pressure, the outer plug 31 provided with a silica gel sealing ring rapidly sprays the tear gas liquid preassembled in the front part of the lumen to the outside of the launch hole, the initial velocity can reach 118 meters per second, which fully meets the requirements of the single police tear gas sprayer equipment that the initial velocity is 90-180 meters per second.

The sleeve 3 has a launching chamber that forms a sealing piston fit with the launching piston 41. The launching chamber has a liquid cavity 33 between the launching piston 41 and the locking head 7 to contain tear gas liquid. The liquid cavity 33 and the tear gas liquid in the liquid cavity 33 constitute the tear gas unit. When the tear gas liquid is launched along the launching hole, the outer plug 31 is impacted and detached from the launching hole. The setting of the elastic connecting strip 32 can play a corresponding limiting role for the outer plug 31, effectively preventing the outer plug 31 from being impacted and flying out and hitting the human face.
