A vehicle-mounted air purifier 1 includes a main unit incorporating an ion generator. The main unit is removably arranged within a passenger space inside a vehicle. For example, if a beverage container holder 90 is provided inside the vehicle, the main unit can be removably arranged within the passenger space when given a cylindrical shape that permits it to be held in the beverage container 90. The power from which the vehicle-mounted air purifier 1 operates can be taken from a cigarette lighter power outlet 91 provided inside the vehicle through a connection cable 92. The main unit is thus arranged directly within the passenger space, and the ions generated by the ion generator inside are fed into the passenger space with higher efficiency. The main unit is removably arranged as an independent unit. Thus, even when the ion generator breaks down or otherwise its replacement becomes necessary, the arranged ion generator can be removed readily and replaced easily.

The invention claimed is: 1. An air purifier for mounting on a vehicle, comprising a main unit incorporating an ion generator that generates positive ions, negative ions, or both positive and negative ions, wherein the main unit is removably arranged within a passenger space inside the vehicle, wherein the main unit further includes a blower for sucking in air outside the main unit to feed the air to the ion generator, wherein, in the ion generator, a discharge surface on which ions are generated by electric discharge is arranged along a direction in which air is blown out by the blower, wherein the main unit further includes a guide plate for guiding the air blown out from the blower so that the air strikes the discharge surface at an acute angle, and wherein the main unit further includes a display section on which an indication corresponding to an operation mode of the ion generator is displayed. 2. The air purifier of claim 1, wherein the main unit is so shaped as to fit in a beverage container holder provided inside the vehicle. 3. The air purifier of claim 1, wherein the main unit is formed in a shape that fits in a beverage container holder provided inside the vehicle. 4. The air purifier of claim 3, wherein the main unit is cylindrical. 5. The air purifier of claim 2, wherein the beverage container holder is located below a first outlet through which air for air-conditioning of an inside of the vehicle is blown out, wherein the main unit includes a second outlet through which air containing ions generated by the ion generator is blown out, and wherein the second outlet is so located that, when the main unit is held in the beverage container holder, the air containing the ions is mixed with the air for air-conditioning that is blown out through the first outlet. 6. The air purifier of claim 1, wherein the main unit further includes a compressing member for compressing air that is discharged out of the main unit through the ion generator. 7. The air purifier of claim l, wherein the main unit is composed of a plurality of separate housing members bonded together, and wherein the display section is formed along a face at which the separate housing members are bonded together. 8. The air purifier of claim 7, wherein the display section is so formed as to extend over a plurality of faces forming the main unit. 9. The air purifier of claim l, further comprising: a light-emitting device that emits light of a color displayed on the display and that feeds the light to the display section; and a display circuit board that supports the light-emitting device, wherein the display circuit board has a corner thereof cut out to form a cut portion, and wherein the display circuit board supports the light-emitting device so that the light emitted from the light-emitting device travels through the cut portion to behind the display circuit board. 10. The air purifier of claim 1, wherein the main unit further includes a connection portion that is connected to a cigarette lighter power outlet provided inside the vehicle. 11. The vehicle mounted air purifier of claim 10, wherein the main unit includes a plurality of ports through which to run a cable for connecting between the cigarette lighter power outlet and the connection portion, the ports being located at different levels in a height direction of the main unit. 12. The air purifier of claim 1, wherein the main unit further includes a voltage step-up coil for stepping up a voltage fed from a power source to drive the ion generator and a shielding member that covers the voltage step-up coil. 13. The air purifier of claim 12, wherein the shielding member covers the voltage step-up coil from both sides of a circuit board on which the voltage step-up coil is arranged. 14. The air purifier of claim 1, wherein an operation mode of the ion generator is changed according to a traveling speed of the vehicle in which the main unit is mounted. 15. The air purifier of claim 1, further comprising: monitoring means for monitoring vibration commensurate with a traveling speed of the vehicle in which the main unit is mounted, and a controller that changes the operation mode of the ion generator according to a degree of the vibration monitored by the monitoring means. 16. The air purifier of claim 1, further comprising: a light-emitting device that is lit according to an operation mode of the ion generator; a light guide member that propagates light emitted from the light-emitting device; and a circuit board that supports the light-emitting device, wherein the light guide member is formed substantially in a U-like shape so as to extend along a top and circumferential faces of the main unit, wherein the circuit board is arranged parallel to the top face of the main unit, and supports the light-emitting device such that the light emitted from the light-emitting device reaches not only a surface of the circuit board facing the light-emitting device but also, through a cut portion formed by cutting off a corner part of the circuit board, an opposite face thereof. 17. The air purifier of claim 1, further comprising a circuit selectable to select a selected operation mode of the ion generator that generates one of positive ions, negative ions, or both positive and negative ions.
