CHEMICAL EVAPORATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a chemicals evaporation device for evaporating various chemicals such as insecticide in air, especially provide an improved means for informing of the life of a carrier impregnated or filled with the chemicals. SOLUTION: A working time memory composed of a plurality of resistance fuses is incorporated in a chemicals cartridge 2 and the fuses are melted by a controller 5 of the evaporation device one by one according to the lapse of working time. The worked time of the chemicals cartridge 2 in the past can be estimated from the number of molten fuses even by removing the cartridge from the device and setting again to the device. Sure management and information of the usable time limit can be performed by the device.
