The fire extinguisher siphon is implemented through the siphon phenomenon, and its working principle is similar to the principle of drinking water from the drinking pipe. When the pressure in the pressure cylinder of the fire extinguisher is lower than atmospheric pressure, the fire extinguishing agent inside the fire extinguisher will be sucked out through the siphon and sprayed to the fire source. The internal tilt design of the siphon can ensure that the fire extinguishing agent is more easily sucked out and the fire extinguishing effect is better

Fire extinguisher siphon is an important part of the fire extinguisher, its shape structure is relatively simple, siphon is usually made of plastic or metal and other materials, the finished size is small, easy to store and carry. When the fire extinguisher is used, the siphon needs to be inserted in the nozzle of the fire extinguisher and is responsible for sucking the fire extinguishing agent such as dry powder or carbon dioxide into the nozzle and spraying it out, so as to achieve the purpose of extinguishing the fire
