Title:
TEMPERATURE-SENSING SELF-STARTING GAS SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/248760
Kind Code:
A1
Abstract:
A temperature-sensing self-starting gas source device, comprising a composite solid propellant (11), a needle puncture percussion cap (12), a firing pin (13), springs (14), a linkage mechanism (15) and a fire-fighting temperature-sensing glass bulb (16); the composite solid propellant is encapsulated in a housing, the composite solid propellant at the bottom of the housing is connected to the needle puncture percussion cap, and an opening is provided at the top of the housing and is used for the escape of gas generated when the composite solid propellant is decomposed; the firing pin is provided at the bottom end of the needle puncture percussion cap and is at a predetermined distance from the bottom end of the needle puncture percussion cap, and the firing pin strikes the needle puncture percussion cap by means of a stroke movement so that the needle puncture percussion cap ignites the composite solid propellant; the linkage mechanism is connected to the firing pin, the fire-fighting temperature-sensing glass bulb and the springs; the linkage mechanism enables the springs to form a compression force in the direction of connection with the fire-fighting temperature-sensing glass bulb; and when the fire-fighting temperature-sensing glass bulb senses a temperature and breaks, the spring tension is released, and the linkage mechanism drives the movement of the firing pin to generate a force for striking the needle puncture percussion cap.
