A plurality of lower through holes which are circumferentially distributed along the axis of the cylinder sleeve are formed in the side wall of the cylinder sleeve. The side wall of the piston is provided with side holes with the outer ends being in one-to-one correspondence with the lower through holes, and the number of the side holes is the same as that of the lower through holes. The lower end of the piston is provided with a connecting hole with the upper end communicating with the inner ends of the side holes. The upper end of the compressed gas storage tank is provided with a gas outlet pipe opposite to the connecting hole. The gas outlet pipe is provided with a sealing membrane. The suspension-type automatic fire extinguisher can be automatically started for putting out a fire when the fire breaks out.

Description

Technical field [0001] The invention relates to the field of fire fighting equipment, in particular to a suspended automatic fire extinguisher. Background technique [0002] The fire hazard is great. It is found that the fire extinguishing device used to extinguish the fire in time can reduce the loss. The fire extinguisher is a commonly used fire extinguishing device; the invention of the Chinese patent application number: CN200480035270.0 discloses a fire extinguisher with at least one indicating device located on it. The indicating device provides visual and / or audible signals so as to allow the user to quickly find the fire extinguisher in an emergency. Although the fire extinguisher can alarm in time when a fire occurs, it has the shortcoming that it cannot automatically start fire extinguishing when used in unattended situations; therefore, the design of a suspended automatic fire extinguisher that can automatically start fire extinguishing when a fire occurs has become an ...
