Fire extinguishing gas spray device

Abstract

A fire extinguishing gas spray device having a gas container (11) in which a pressurized fire extinguishing gas is placed and where a sealing plate (13) is attached to an opening of the container, cases (1, 10) that can receive the gas container (11), a seal breaking member (45) that has a point section (45a) capable of breaking the seal of the sealing plate (13), a seal breaker holder (21) wherethe seal breaking member (45) is installed, and a container holder (15) to which a mouth portion of the gas container (11) is removably attached and that has inside a through-hole (17) that receives the seal braking member (45) in a movable manner. The seal breaker holder (21) and the container holder (15) are approachable relative to each other. Communication paths (31-33) that interconnect the through-hole (17) and a spray hole (3) in an exterior portion are provided with a control valve (38) that can block the communication paths (31-33). A lighting device (48) that can be lit when the sealing of the sealing plate is broken is placed exposed on the surface of the cases (1, 10). The fire extinguishing gas spray device has an annunciator (53) that issues an alarm based on a fire occurrence signal or an earthquake occurrence signal from a disaster alarm device.

Description

technical field [0001] The invention relates to a fire extinguishing gas injector, which is suitable for simple fire extinguishers such as households or offices or vehicles, which can make the filled small gas cylinders easy to break, and use a valve to temporarily prevent the outflow of the sprayed fire extinguishing gas. Prevent the waste of fire extinguishing gas, realize the effective use of fire extinguishing gas and the effect of fire extinguishing, at the same time, spray the fire extinguishing gas toward the fire source effectively and reliably when extinguishing the fire, realize effective fire extinguishing and reliable initial fire extinguishing, and notify the fire extinguisher when a fire occurs The location of the fire extinguisher is promoted to use the fire extinguisher quickly and to put out the fire at the beginning. Background technique [0002] For example, ordinary fire extinguishers that are usually installed in homes or offices are large and heavy, req...

AI Technical Summary

Problems solved by technology

[0007] However, among the above-mentioned simple fire extinguishers, the fire extinguishers that rotate the cylinder or cover have the following problems: the displacement of the striker relative to the amount of rotation is relatively small, so that the sealing plate can be fully broken. , it is necessary to increase the amount of rotation of the cylinder or cover, so that it takes time to break the seal and cannot quickly extinguish the fire

[0008] In addition, the fire extinguisher that pushes down the operation block has the following problems: the operation of moving the safety block back and pressing the operation surface is required, and the operation during fire extinguishing becomes complicated

[0009] 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

[0010] Moreover, there is the following problem in the above-mentioned fire extinguishers: although the nozzles are all directed towards the fire source to break the seal, the operation is concentrated on breaking the seal during fire extinguishing, so it is difficult to reliably release the fire extinguisher. The nozzle faces the fire source, and as a result, the initial ejected gas is wasted, or it cannot be effectively used for fire extinguishing, and the opportunity for initial fire extinguishing is missed. The fire extinguishing effect corresponding to the filling volume cannot effectively use the gas

[0014] 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 it is time-consuming and cannot be used quickly because it requires manpower to send an alarm, etc.
