A third problem solving means is that the drive of the air purifier body is controlled by the signal of the indicator light detector.

[0011]

According to the first means for solving the above problems, the present invention provides:
Whether or not the vehicle is being driven can be detected based on whether or not the foot brake is stepped on within a certain time, and the operation of the air purifier body can be continued only when the vehicle is being driven.

According to the second means for solving the problems described above, according to the present invention, it is possible to detect whether or not the vehicle is being driven by whether or not the turn signal has been used within a predetermined time. Only the air purifier can continue to operate.

According to the third means for solving the problems described above, according to the present invention, it can be detected whether or not the vehicle is being driven depending on whether or not the foot brake or the direction indicator has been used within a predetermined time, and the vehicle can be driven. The operation of the air purifier can be continued only when

[0023]

As is apparent from the above embodiments, according to the present invention, a stop lamp detector for detecting a change in the potential of the power wiring of a stop lamp of an automobile and a control circuit for controlling the drive of the air purifier body. Since the drive of the main body of the air purifier is controlled by the signal of the stop lamp detector, whether or not the vehicle is in a driving state depending on the potential change of the power wiring of the stop lamp wired at the rear of the vehicle. Can be detected and only one detection line is required,
The air purifier main body can be started and stopped very easily without using the wiring dedicated to the vehicle interior.

Further, in place of the stop lamp detector, there is provided an indicator light detector for detecting the potential change of the power supply wiring of the indicator light of the automobile direction indicator, and the air purifier main body is provided by the signal of the indicator light detector. It requires two detection lines because it controls the driving of the car.However, in some cases, such as highways, the foot brake may not be stepped on for a long time, but in the case of overtaking or entering the service area, the lane is changed. Since the direction indicator switch is used more frequently, the air cleaner body can be started and stopped more reliably.

Further, in addition to the above stop lamp detector, an indicator light detector for detecting a potential change in the power supply wiring of the indicator light of the turn indicator of the automobile is provided, and the air purifier main body is provided by the signal of the indicator light detector. Since the drive of the air cleaner is controlled, it is possible to reliably start and stop the main body of the air purifier according to various operating conditions by using the signals of both the stop lamp detector and the indicator light detector. .
