Odor generation alarm and method for informing unusual situation

摘要

An odor generation alarm and a method for informing an unusual situation having a high attention attracting effect and a high degree of safety are provided. An odor generation alarm includes an odorant receptacle, a drive section, a detector and a circuit section which is a controller. The odorant receptacle contains an odorant. A concentration of the odorant in air at which a person can no longer tolerate a strength of smell is lower than a no observed effect concentration of the odorant. The drive section causes the odorant to be emitted from the odorant receptacle. The detector detects occurrence of an unusual situation, and outputs a detection signal. When the detection signal from the detector is inputted, the controller causes the drive section to emit the odorant in accordance with the detection signal.

主权项

1. An odor generation alarm, comprising:
an odorant receptacle which includes a nozzle head and a pressure container containing an odorant; a tubular casing which houses the odorant receptacle therein; a drive section which emits the odorant from the odorant receptacle; a detector which detects occurrence of an emergency, and outputs a detection signal to a controller, wherein the odorant includes allyl isothiocyanate, the controller causes the drive section to emit the odorant into an object section in which the odor generation alarm is used in accordance with the detection signal, when the detection signal is inputted from the detector, and the drive section causes the odorant to be emitted from the odorant receptacle, and makes concentration in air of allyl isothiocyanate in the object section by 5 ppm or more and 20 ppm or less by amount of substance when the odorant is diffused evenly in the object section, wherein the nozzle head is fixed to the casing, and the pressure container is movable in an axial direction of the casing toward the nozzle head, the drive section includes a piston movable in the axial direction of the casing, and the piston, upon being activated, displaces the pressure container toward the nozzle head to emit the odorant from the odorant receptacle.
