Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, a main body case (hereinafter referred to as a main body) constituting an outer shell of the vehicle-mounted air purifier is formed of a lower main body 21, an upper main body 22, and a lid 23, and a filter 24 is provided therein.
A box-shaped filter support (corresponding to a dust collecting unit) 25 for mounting a fan, and a box-shaped fan chamber (corresponding to a fan unit) 28 having a built-in blower fan 26 and fixing a blower fan drive motor 27 are respectively provided in the main body. And are independently formed and deployed. The lid 23 has an intake port 30 at a position facing the filter 24, and an exhaust port 31 on the side of the upper body 22. The filter 24 is composed of a charging filter 32 formed into a thick plate by bending a thin filter material into a folding screen shape and surrounding the outer periphery with a reinforcing material, and a flat activated carbon filter 34, and is attached and detached when the lid 23 is opened. be able to. The filter support 25 has a box-like shape in which the outer periphery of the filter 24 is tightly covered and the bottom surface is opened, and a U-shaped rib (corresponding to a wall) 3 is provided below.
5 is formed so as to open toward the fan chamber 28. The motor 27 is fixed to the top of the fan chamber 28, and the suction port 3 is
6, a discharge port 37 is formed in the side wall. Further, from the bottom surface of the fan chamber 28, a U-shaped rib (corresponding to a wall) 38 which is in contact with the lower main body 21 is formed so as to open toward the filter support 25, and a U-shaped rib 35 is formed. The U-shaped rib 38 and the lower body 21 form an air passage communicating the filter 24 and the fan chamber 28.

In the above configuration, when the motor 27 is driven, the air inside the vehicle sucked through the air inlet 30 absorbs dirt into the charging filter 32, and the odor particles are absorbed into the activated carbon filter 34.
