摘要： The present invention relates to an automatic fire extinguishing system for small spaces using fire extinguishing agents comprising the automatic fire extinguishing system to be installed in a small space, wherein the moving member is moved by an elastic body installed in the housing when the glass bulb installed in the housing is broken by heat from a fire; the fire extinguishing agents breaks the membrane of the tank storing the pressurized fire extinguishing agents with the striking member connected with the moving member; the striking member connected with the moving member breaks the membrane of the tank which stores pressurized fire extinguishing agents; and the pressurized fire extinguishing agents are spread to the small space, which leads to suppressing the fire at an early stage. When a fire breaks out in a small space susceptible for a fire such as distribution boxes, substation boxes, refrigerators, server racks, etc., the glass bulb installed inside the housing will be broken by heat; the moving member is moved by the elastic force of the elastic body; the striking member breaks the membrane blocking the opening of the tank; and the fire extinguishing agents pressurized in the tank are dispersed, which makes it easier to suppress a fire at an early stage.

摘要： An automatic fire extinguishing system has a tank that contains fire extinguishing agents, and a housing. The housing has a glass bulb retained therein where the glass bulb is exposed by a side connecting hole, and contacted by a moving member that is biased by an elastic body against the glass bulb. When heat is transferred via the side connecting hole to the glass bulb to break the glass bulb, the elastic body biases the moving member to cause the guiding bars to push a striking member so that a striking protrusion on the striking member breaks a membrane that covers the opening of the tank, thereby allowing the pressurized fire extinguishing agents to escape.
