[0002] A fire extinguisher is a portable fire-fighting tool. Chemical substances are placed inside the fire extinguisher to extinguish fires. Fire extinguishers are one of the common fire prevention facilities and are stored in public places or where fires may occur. Different types of fire extinguishers are filled with different components and are designed for different causes of fires. Similarly, a large number of fire extinguishers need to be configured in mine safety production.

[0003] Chinese Patent (authorized announcement number: CN 212536670 U) proposed a fire extinguisher valve. The patent includes a valve body, a valve stem, a handle, a pressure handle, and a safety pin. The characteristics are as follows: an extension plate is provided at one end of the handle away from the valve body, one end of the extension plate is fixed to the handle, and the other end of the extension plate extends in a suspended manner. The utility model has the advantage of more comfortable use.

[0004] However, the seal of the fire extinguisher in the above patent seals the bottle mouth by the elastic action of a spring, and the sealing performance is poor. If the fire extinguisher is not used for a long time, the outside of the valve body is prone to aging under the long-term action, and a gap is likely to be generated between the valve body and the bottle body, thereby affecting the sealing performance. To improve the sealing performance of the mine fire extinguisher, we propose a triggering device for a mine fire extinguisher. Summary of the Utility Model
