The present invention relates to a vehicle-mounted air purifier. A vehicle-mounted air purifier according to the present invention includes M (M >；= 2) photocatalytic panels, each of which is molded in a form of a panel having specified thickness T (T >；= 5) mm by integrating a plurality of silicon component beads coated with a photocatalytic material； a panel arrangement frame part for disposing and fixing the M photocatalytic panels in a specified geometrical structure so as to form an air passage in an empty space for flowing air between the M photocatalytic panels； an ultraviolet (UV) lamp part provided at a specified position on the air passage formed in the empty space between the M photocatalytic panels to emit UV light having a wavelength of 320 nm to 405 nm； a suction part for sucking surrounding air； a fan part for allowing the air sucked through the suction part to flow into the air passage formed in the empty space between the M photocatalytic panels； a fan arrangement frame part for disposing and fixing the fan part in a geometrical structure to generate vortex or turbulence in air flowing through the air passage between the M photocatalytic panels by the fan part； and a discharge part for discharging purified air to an outside, wherein the purified air includes a component decomposed through a specified chemical reaction based on the catalytic action of the photocatalytic material coated on the beads based on the UV emitted from UV lamp part, and the beads constituting the photocatalytic panel flow through the air passage between the M photocatalytic panels.본 발명은 차량 거치형 공기청정기에 관한 것으로, 본 발명에 따른 차량 거치형 공기청정기는, 광촉매 물질이 코팅된 복수의 규소 성분 구슬들을 집적하여 지정된 두께 T(T≥5㎜)의 패널 형태로 성형한 M(M≥2)개의 광촉매 패널와, M개의 광촉매 패널 사이에 공기를 유동시키는 빈 공간의 공기 통로를 형성하도록 상기 M개의 광촉매 패널을 지정된 기하학 구조로 배치 고정하는 패널배치프레임부와, 상기 M개의 광촉매 패널 사이의 빈 공간에 형성된 공기 통로 상의 지정된 위치에 구비되며 320~405nm 파장의 UV(UltraViolet)를 방출하는 UV램프부와, 주변의 공기가 흡입되는 흡입부와, 상기 흡입부를 통해 흡입된 공기를 상기 M개의 광촉매 패널 사이의 빈 공간에 형성된 공기 통로로 유동시키는 팬부와, 상
