     BACKGROUND OF THE PRESENT INVENTION  
      1. Field of the Present Invention  
      The present invention relates to a vehicular photoelectron air purifier, and more particularly, it relates to an air purifier with a replaceable UVC emitting light, which can eliminate virus,  bacillus  and mildew and etc. in the air through purifying the air by a polarization end ultraviolet ray, with a vehicular power supply besides the municipal power supply.  
      2. Description of Related Arts  
      Insufficient ventilation of indoor or an enclosed room readily makes the air dreggy and leads to the virus and  bacillus  propagated and spread. In a public and an air conditioning room, therefore, it is necessary to manually purify the air and eliminate virus and  bacillus  without delay for keeping fresh air in a given room or an area. In an air conditioning room during summer period, purification of indoor air is also a very important problem that is difficult to deal with. More and more attentions are drawn to indoor air purification due to wide diffusion of SARS virus. In a conventional method, an ultraviolet light for eliminating  bacillus  may cause injure by irradiating human body. In addition, the present conventional ventilating and air conditioning equipment have no air purifying function, which generally are equipped with simple deducting and filtering devices, and it is not cost effective to replace one during mass production. In addition, insufficient ventilation of car, train, airplane, and ship department will also cause the same concerns as described and conventional methods are not sufficient to provide solution. Moreover, none of the present conventional air purifier provides any mean of replaceable UVC emitting device for consumer to replace any malfunction UVC emitting light.  
     SUMMARY OF THE PRESENT INVENTION  
      A main object of the present invention is to provide an air purifier with a replaceable UVC emitting light to overcome the defects in the prior art, and to provide vehicular photoelectron air purifier for purifying the air with high efficiency through the ultraviolet and through such way as combing the ultraviolet and the negative ion by a power supply powered of transportation vehicles such as cars and ships.  
      Accordingly, a vehicular photoelectron air purifier is disclosed; a main body is a square-columnar structure comprises a plurality of extractor fan, a plurality of transformer, a plurality of circuit board, and a plurality of polarization end, a plurality of ultraviolet ray radiation tube (an UVC emitting device), a plurality of an assembly of an assembly of replaceable ultraviolet ray radiation tubes. Said body is equipped with one air inlet and one air outlet; said air outlet locates at front portion of said body and an air exhaust frame trellis device is provided on a plane of a front end surface of said body; said air inlet locates at a rear portion of said body and said air intake frame trellis device is provided at said rear end of said body; said intake frame trellis device provides an air inlet and is used as a fixed dustproof frame, dustproof net and dustproof cover; said extractor fan is kept close to an inner surface of said air exhaust frame trellis device; there is an air collector between said air inlet and said extractor fan; said polarization end ultraviolet ray radiation tube lies in a center portion of said air collector.  
      According to another aspect of the present invention, a vehicular photoelectron air purifier is provided, a main body of which is a square-columnar structure comprising a plurality of extractor fan, a plurality of transformer, a plurality of circuit board, a plurality of polarization end ultraviolet ray radiation tube, (an UVC emitting device), a plurality of an assembly of an assembly of replaceable ultraviolet ray radiation tubes and a plurality of cathodal high-voltage discharging carbonized fiber wire.

      Since ultraviolet has outstanding effect for eliminating virus,  bacillus  and mildew, the air, under actions of said extractor fan, is forced to pass through around said ultraviolet light tube for the purpose of eliminating virus,  bacillus  and mildew; because there are two extractor fans arranged abreast along a linear direction of said polarization end ultraviolet ray tube, the air flow increases in amount and treating capacity strengthens so as to sufficiently eliminate virus,  bacillus  and mildew in the air.  
      The present invention, employs said polarization end ultraviolet ray to eliminate virus,  bacillus  and mildew in air; meanwhile, said cathodal high-voltage discharging carbonized fiber wire can increase negative ions in the environment; when the air is drawn into said purifier by said fan, two continuously alternating working modes are available, i.e.; both said ultraviolet radiation and said high voltage ionization negative ion are automatically and alternatively operated so as to provide ideal air purifying effect. A sheltering wall and said air collector are provided around said polarization end ultraviolet ray radiation tube in said main body of the present invention, therefore, said ultraviolet ray shall not irradiate to outside of said main body and thus preventing eye injure of users from leakage of ultraviolet; said purifier of the present invention can use both the municipal power supply and any power supply of transportation vehicles, so it is convenient for carrying and using and applicable for various places.  
      The present invention employs said assembly of an assembly of replaceable ultraviolet ray radiation tubes to provide a mean of replacing used and dirty ultraviolet ray radiation tube for consumers without the hassle of open up said air purifier when replacing said used and dirty ultraviolet ray radiation tube
