Abstract:
An adsorbing device comprising:a main body having an intake port and an exhaust port and accommodating therein an adsorbing composition capable of adsorbing a gaseous specific substance; regenerating means attached to the main body for releasing the specific substance from the adsorbing composition; a sensor capable of detecting the specific substance arranged at least near the exhaust port of the main body; and a control unit for instructing the regenerating means to operate when the sensor detects the specific substance at a higher value than a predetermined value, the sensor comprising a first sensor arranged near the exhaust port and a second sensor arranged near the intake port, the regenerating means being a magnetron capable of emitting a microwave which heats the adsorbing composition, and the control unit instructing the magnetron to operate on the basis of the relative difference between a value detected by the first sensor and a value detected by the second sensor.
