[0036] The second preferred embodiment of this invention is a vertical vehicular photoelectron air purifier. It uses a polarization end ultraviolet ray radiation tube to radiate the polarization end ultraviolet ray which can eliminate virus, bacillus and mildew contained in the air flowing through the polarization end ultraviolet ray radiation tube, and meanwhile the negative ion in the air can be increased through the operation of the anion machine.

[0037] The vertical vehicular photoelectron air purifier of this invention mainly includes: extractor fan, polarization end ultraviolet ray radiation tube and cathodal high-voltage discharging carbonized fiber wire. When the air is drawn into this photoelectron air virus and bacillus killing device, two continuously alternating working modes are available; the first one is intermittent (about 3 to 4 minutes) cathodal high-voltage output discharging via the carbonized fiber, the ionized air produces negative ion and is exhausted through the fan; the other one is intermittent (about 7 to 10 minutes) igniting the polarization end ultraviolet ray radiation tube to radiate the polarization end ultraviolet ray which can eliminate virus, bacillus and mildew in the air that flows through the tube. This photoelectron air purifier is equipped with one air inlet and one air outlet. The cathodal high-voltage discharging fiber wire is mounted at the air outlet, the polarization end ultraviolet ray radiation tube is mounted at the said air inlet in the body, and the fan is fixed at the air outlet in the body. When the air containing virus, bacillus and mildew is drawn into the body through the air outlet, the flowing air can easily enter and traverse through the air intake frame trellis device of the photoelectron air purifier and then reach the air exhaust frame trellis device so that the air containing virus, bacillus and mildew must contact with the polarization end ultraviolet ray radiation tube and thus the polarization end ultraviolet ray eliminates virus, bacillus and mildew contained in the air; then the air is purified by the anion machine, and the clean air containing the negative ion is exhausted out of the air outlet so as to improve the air quality indoor.

[0038] This product has a square-columnar structure, with air inlet, extractor fan, polarization end ultraviolet ray radiation tube, and air outlet etc. arranged vertically.

[0043] In the practice, when the vertical vehicular photoelectron air purifier is operated, the air containing virus, bacillus and mildew is drawn by the extractor fan 10 into the air collecting wall 18 (behind which there are many long grids) in the body 1 through the dustproof net 7 , so the flowing air can easily enter into the air collecting wall 18 and then reaches the air exhaust frame trellis device 2 . The polarization end ultraviolet ray radiation tube 16 is provided in the center of the air collecting wall 18 ; this means that when the air containing virus, bacillus and mildew flows and enters the air collecting walls 18 and 19 , and then enters into the air inlet 20 between the polarization end ultraviolet ray radiation tube 16 and the air collecting wall 19 , the polarization end ultraviolet ray radiation tube 16 will radiate polarization end ultraviolet ray so as to eliminate virus, bacillus and mildew contained in the air; now the purified air is drawn into the cathodal high-voltage discharging carbonized fiber wire 23 of the air exhaust frame trellis device 2 to produce negative ion, and then the clean air containing the negative ion is exhausted out of the air exhaust frame trellis device 2 so as to improve the air quality indoor.

[0044] The sheltering walls 21 are provided at the front and rear of the said air collecting wall 18 and used for prohibiting user's eyes from injure by the polarization end ultraviolet ray radiating to the outside of the body 1 .

[0045] The circuit principle of the vertical vehicular photoelectron air purifier is as follows: the input power supply is supplied to an anion high-voltage generating circuit through the switch 15 , providing a negative high-voltage output. The input power supply is also supplied to the extractor fan 10 via the speed control circuit followed after a full wave band rectifying circuit, and operating the full wave rectifying circuit of the polarization end ultraviolet ray radiation tube 16 via a DC-AC converting circuit. Another input current, via a DC voltage-stabilizing circuit, is supplied to the automatic circulation control circuit of the anion generating circuit and the active circuit of the polarization end ultraviolet ray radiation tube 16 so as to control the alternative operation of the anion generating circuit and the polarization end ultraviolet ray radiation tube 16 . The anion high-voltage output of the electronic circuit system is available within a scope of 4.5 kv-8.5 kv. This control circuit belongs to the prior art, the detailed description is omitted here.

[0046] The potable photoelectric air virus and bacillus killing machine of this invention uses an polarization end ultraviolet radiation ray tube to produce polarization end ultraviolet ray with wavelength of 253.7 nm. The scientific research proves that such ultraviolet ray can eliminate virus, bacillus and mildew contained in the air most effectively; the negative ion in the air can be increased through the operation of the anion machine so as to facilitate the biochemical action and reduce the secretion of the hormone that makes people feel dumps and fatigue.

[0047] The above is only a description over the technical scheme and the preferred embodiments of this invention and not a limitation to the technical scheme of this application. It is obvious that this invention can be realized by many means.
