The invention belongs to a vehicle
air purifier, which is composed of a blower fan; and a first structural member component is formed by a pedestal, a base plate, a ring cover loop and the blower fan. A second structural member component is formed by a
composite filter component, and a third structural member component is formed by a top cover and a primary filter. An upper
transverse plane of the first structural member component and the upper
transverse plane of the second structural member component are flattened, a top sealed cover at the lower
transverse plane of the periphery of the top cover is capable of capping the upper transverse plane of the first structural member component and the second structural member component through
magnetic actuation. The upper transverse plane of the ring cover loop and the upper transverse plane of the blower fan are positioned at same plane; a
filter material is folded to a sawtooth annular body by connecting end to end, and the front transverse plane and the rear transverse plane of the
filter material are a front ventilation supporting piece and a rear ventilation supporting piece, and an intermediate
filter material between the front ventilation supporting piece and the rear ventilation supporting piece is an
active carbon mixing adsorption layer. The vehicle
air purifier has the advantages of small volume, reasonable
filter design, high purifying efficiency, mute performance, and convenient connection, the replacing of the filter material saves labor and saves the time, ventilation is smooth, purifying efficiency is high, security is good, and usage effect is good.
