Fire extinguishing gas spray device and disaster warning system

Abstract

The invention relates to a fire extinguishing gas spray device and a disaster warning system for jetting the fire extinguishing gas to the origin of a fire and informing where the fire extinguisher is when a fire or earthquake occurs. The fire extinguishing gas spray device is provided with: a gas cylinder that charges pressurized fire extinguishing gas therein and attaches a sealing plate on an opening thereof; a seal breaking member that can break the sealing plate; a cylinder holder that is detachably attached with the gas cylinder and movably housing the seal breaking member therein; a seal breaking member holder that is attached the seal breaking member and regularly, biases in the opposite side to the gas cylinder; a communication passage that can communicates a guide hole with an introduction hole opened to the outside, the fire extinguishing gas being jetted out from the introduction hole after the breaking. The disaster warning system can output disaster warning according to the fire disaster detection signal or the vibration detection signal; an annunciator is used for receiving the disaster warning and outputting warning sound or optical signal.

Description

[0001] This application is a divisional application of a Chinese patent application whose application number is 200780001614.X, the application date is April 18, 2007, the applicant is "Yoshida Hideo", and the invention name is "fire extinguishing gas injector". technical field [0002] The invention relates to a fire extinguishing gas injector and a disaster alarm system, which is suitable for simple fire extinguishers used in homes, offices or vehicles, which can make the filled small gas cylinders easy to break, and use the valve to temporarily stop the fire extinguishing of the spray The outflow of gas prevents the waste of fire extinguishing gas, realizes the effective use of fire extinguishing gas and the effect of fire extinguishing. Or inform the location of the fire extinguisher when an earthquake occurs, so as to promote the rapid use of fire extinguishers and initial fire extinguishing. Background technique [0003] For example, ordinary fire extinguishers that ar...

AI Technical Summary

Problems solved by technology

[0008] However, among the above-mentioned simple fire extinguishers, the fire extinguisher that rotates the cylinder or cover has the following problems: the displacement of the striker relative to the amount of rotation is relatively small. In order to fully break the seal of the sealing plate, the rotation amount of the cylinder or cover must be increased. Closing time takes time and cannot quickly extinguish the fire

[0009] In addition, the fire extinguisher that pushes down the operation block has the following problems: the operation of retracting the safety block and the operation of pressing the operation surface are required, and the operation at the time of fire extinguishing becomes complicated.

[0010] In addition, the fire extinguisher that hits the top or bottom of the cylinder is relatively simple to extinguish the fire and can quickly extinguish the fire. However, since the safety plate is exposed to the outside, if the plate is pulled out by pranks or by mistake, the sealing plate may be broken. possibility of

[0011] Moreover, the above-mentioned fire extinguishers have the following problem: Although they all face the fire source with the nozzle port and then break the seal, it is difficult to reliably direct the nozzle port toward the fire source because the fire extinguishing operation is concentrated on breaking the seal, and as a result, the initial blown gas is wasted. , or it cannot be effectively used for fire extinguishing, and the opportunity of initial fire extinguishing is missed. On the other hand, since the residual gas is used for substantial fire extinguishing, the fire extinguishing effect corresponding to the filling amount of the gas cannot be obtained, and the gas cannot be effectively used.

[0015] However, the above-mentioned fire extinguisher has the following problems: a switch is provided on the safety bolt, and the safety bolt is pulled out to make the switch open (ON), which is based on the premise of knowing the location of the fire extinguisher, so it is not helpful to know the location of the fire extinguisher. The fire extinguisher cannot be used if the location of the fire extinguisher is not known, and human hands are required to send the alarm, so it takes time and cannot be used quickly, etc.
