とするガス付臭装置である。According to the present invention, that is, in a gas fire extinguisher, the mouth of a container containing an odorous substance is sealed at the tip of a nozzle through a sealing plate, and gas is discharged from the nozzle. The gas odor device is characterized in that the sealing plate is opened, the odorous substance in the container is agitated, and the fire extinguishing gas and the odorous substance are jetted from a side port communicating with the nozzle side from the nozzle tip.

い。[Function] When a fire occurs, a person in the area is evacuated by an alarm of an audio lamp and the door windows and the like of the area are closed and hermetically closed, and a fire extinguishing device is activated to start extinguishing gas (gas such as CO 2 gas). )
Is sent to the nozzle. With this gas pressure, the sealing plate at the tip of the nozzle is opened by this gas pressure, and the odorous substance in the container is agitated by the radiant gas, and the fire extinguishing gas is odorized and radiated from the nozzle side mouth to fill the area. After the fire is extinguished, the odor will remain and will not attract people unless the air in the area is completely replaced.

向に放射する。FIG. 1 shows a second embodiment of the invention. The nozzle 1 has a discharge port 2 and a side port 4 communicating with the outside of the nozzle 1 at the tip portion 3 thereof. Reference numeral 8 is a port connected to the gas supply pipe of the gas fire extinguisher, and 5 is an opening of the side port 4.
The nozzle 1 seals the container 6 at its tip 3 by facing the mouth of the container 6 containing the odorous substance with a sealing plate 7 therebetween. The discharge port 2 communicates with the side port 4 through the passage 2a. In the first invention, the passage 2a is not provided. Reference numeral 9 is a horn that emits the gas discharged from the side port 4 in a predetermined direction.

は極めて小型とすることができる。Furfuryl mercaptan, for example, is used as the odorous substance. This substance easily emits an odor that is repellent to humans if it is only a few ppm in the air. Since a large number of nozzles are provided in one device in a gas-based fire extinguisher, the container provided with nozzles is only a few cc, and this device can be made extremely small.
【００１０】放射ガスで容器６の封板が容易に開封する
ように、容器６は必ず空気容積を残して臭い物質を収容
するようにする。In order for the sealing plate of the container 6 to be easily opened by the radiant gas, the container 6 must be left with an air volume to contain the odorous substance.
