Abstract
The utility model discloses an automatic fire extinguisher, which comprises a pressurized barrel body and a guide pipe, wherein fire extinguishing material is arranged in the pressurized barrel body; the guide pipe is made of fusible metal or glass or plastics; the pressurized barrel body is connected with one end of the guide pipe by a control valve, and the other end is sealed. The utility model has simple structure; when a fire accident occurs, local temperature is ascended rapidly; when a designed temperature range is obtained, a part of the guide pipe positioned at the accident fire position immediately fuses and then the fire extinguishing material in the pressurized barrel body is sprayed to the accident fire position. Thus, fire behavior is extinguished at the first time. In addition, the utility model solves the disadvantage that the existing control valve of a fire extinguisher can not be in a normally open state. According to the needs of the transportation and the operation of the utility model, the conducting and the cutting-off states of the controlling valve can be adjusted. When the utility model is conducted to work, the utility model is in a fire extinguishing state at any time and can be automatically extinguished accidental fires.
