PURPOSE:To automatically and efficiently deodorize a passenger room after parking for a predetermined time, by outputting a parking confirming signal to a timer circuit when the absent time of a person becomes a predetermined time and supplying driving power to a fine pulverization means from a storage battery body only for a definite time. CONSTITUTION:When a driver's seat becomes empty, the output signal from a detection apparatus 50 becomes a low level from a high level. A time monitor circuit 60 operates a timer in timing wherein the output signal of the detection apparatus 50 becomes a low level from a high level and, when the output signal of the detection apparatus does not become a high level within a predetermined time, a high level parking confirming signal is outputted to a timer circuit 40 at the point of time when a certain timer operating time is elapsed and the timer circuit 40 receives said signal to operate and connects an input side and an output side only for a definite time to supply driving power to a motor 21 and a heat generator 33 from a battery 70. By this constitution, a deodorizing liquid is heated and evaporated by the heat generator 33 and the generated vapor is mixed with inflow air by the wind pressure formed by a fan to be sent out from an air outlet and diffused into a passenger room of the vehicle. |
