Automatic trigger type fire extinguisher

Abstract

The invention relates to a fire extinguisher, in particular to an automatic trigger type fire extinguisher. The automatic trigger type fire extinguisher comprises a film breaking device capable of breaking a sealing film. The film breaking device is a seal pressure-resistant film, or the film breaking device is a temperature-sensing piercing assembly, or the film breaking device is a temperature-sensing piercing assembly with a temperature control circuit, or the film breaking device is a plasma high-temperature discharging assembly, or the film breaking device is a comprehensive film breaking device comprising the seal pressure-resistant film, the temperature-sensing piercing assembly and the plasma high-temperature discharging assembly; combustion film breaking, film piercing and breaking and film breakdown and breaking of the sealing film can be triggered automatically, and therefore automatic fire extinguishing is achieved; and control over valve opening fire extinguishing at the voltage of 5 V below is achieved, and a control circuit with the voltage of 5 V below can be connected directly. By the adoption of the technical scheme, for the combustion point detection range, the application is wide, the structure is simple, the manufacturing and use cost is low, and the automatic trigger type fire extinguisher is suitable for fire protection engineering in multiple fields in the reality, and popularization is easy.

Description

technical field [0001] The invention relates to a fire extinguisher, in particular to an automatic trigger fire extinguisher. Background technique [0002] Fire extinguishing equipment is an important equipment in the event of a fire, especially automatic fire extinguishing equipment. By placing it in public facilities, industrial and mining enterprises, aerospace railway ships, buildings and other environments, it can immediately extinguish the burning point and avoid further expansion of the fire. [0003] Automatic fire extinguishing equipment in the prior art is roughly divided into two ways to trigger automatic fire extinguishing. One is to use electronic equipment, such as temperature detection, smoke detectors, etc., to detect the occurrence of a fire, so as to open the solenoid valve switch of the automatic fire extinguishing device, so that the fire extinguishing material is sprayed out, and the other is to use glass bubbles similar to thermometers as the nozzles of...

AI Technical Summary

Problems solved by technology

[0004] No matter what kind of automatic fire extinguishing equipment, there are limitations in the actual application range, such as: temperature detection and / or smoke detector, solenoid valve control automatic fire extinguishing equipment, in larger warehouses, temperature detection and / or smoke detectors Sensors can only be installed on walls, pillars, and beams on the top of warehouses. Once a burning point appears far away from walls, pillars, and beams, the temperature or dense smoke will be transmitted to temperature detection and / or smoke detectors. For a certain period of time, the burning point cannot be extinguished in time

Another example: the glass bubble is used as a fire extinguishing device for sealing the nozzle. When the glass bubble is far from the burning point, it cannot be broken in time, and the fire cannot be extinguished in time.
