Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a bottle mouth structure of a fire extinguishing device. Background Technique

[0002] Fire fighting is to eliminate potential hazards and prevent disasters, that is, the general term for preventing and solving man-made and natural and accidental disasters encountered in the process of people's life, work and study. Of course, the narrow meaning in the initial stage of people's understanding is: the meaning of extinguishing fires. There is an existing patent, patent publication number CN211327903U, which discloses a non-pressure-stored automatic fire extinguishing device, including a fire extinguishing agent tank and a gas generating tank; the fire extinguishing agent tank is in the shape of a grenade, and an isolation cup is embedded and sealed at the bottle mouth of the fire extinguishing agent tank. A liquid fire extinguishing agent is filled in the cavity between the isolation cup and the fire extinguishing agent tank. A gas generating tank filled with a gas generating agent is installed inside the isolation cup, and a thermal sensitive wire built in the gas generating tank passes through the plug of the gas generating tank and extends to the outer wall of the fire extinguishing agent tank for detecting fire signals and starting the fire extinguishing device. The utility model adopts a structure with a pre-crack set on the fire extinguishing agent tank body, so that the fire extinguishing agent tank does not generate fragments during the operation of the fire extinguishing device, and the opened part can only move in the vertical direction, which not only improves the use efficiency of the fire extinguishing agent, but also avoids the damage to surrounding items when the fire extinguishing agent tank bursts.

[0003] In view of the above related technologies, the inventor believes that there are the following defects: in the actual application process, manual operation is required to carry out fire extinguishing operations. When a fire breaks out, the bottle mouth cannot be automatically opened for fire extinguishing operations, which affects the normal use of the subsequent bottle mouth structure and reduces the use convenience of this structure. Therefore, we propose a bottle mouth structure of a fire extinguishing device to solve the above existing problems. Content of the Utility Model

[0033] During operation, the structure is installed at the position to be protected. When a fire occurs, the fire causes the gas inside the horizontal pipe 5 to heat up and expand, and then drives the conical rod 8 on the piston 6 to squeeze the glass plate 9, causing the glass plate 9 to break. Subsequently, the return spring 10 returns the insertion rod 7 on the piston 6, so that the insertion rod 7 cancels the limit on the cover body 4, and then the mouth of the gas tank 3 is opened, so as to facilitate the subsequent use process.
