Claims

[Scope of utility model registration request]

A passage 20 that communicates with the space outside the vehicle and the space inside the vehicle and allows outside air and inside air to circulate; and a passage 20 that is arranged inside the passage 20 and selectively directs the outside air and inside air into the inside of the passage 20 according to the direction of rotation. A fan 22 that causes air to flow into the air, a DC motor 23 that rotates the fan 22, a gas sensor 21 that is disposed inside the passage 20 and outputs the concentration of contaminants in the outside air and inside air that flow into the passage 20, and the DC motor 23 is supplied with driving power to change the rotation direction of the passage 20 at a predetermined period.
It has a detection control means 24 that detects the concentration of contaminants in the outside air and inside air flowing into the interior by the gas sensor 21 in synchronization with the predetermined period, and the one gas sensor 21 accurately detects the concentration of contaminants in the outside air and inside air. A vehicle interior and exterior air pollution detection device characterized by the following.
