In technical scheme preferably, described air inlet is the side plate that is provided with cellular through hole.

In technical scheme preferably, filter disc group from left to right respectively: metallic sieve, active carbon filter screen, HEPA screen pack and photo-catalytic filtering screen.

In technical scheme preferably, the brush of anion generator is located at gas outlet place.

In technical scheme preferably, housing adopts aluminium alloy or PVC material.

In technical scheme preferably, in face shield, be provided with activated charcoal strainer.

In technical scheme preferably, battery is the battery that can discharge and recharge continuously.

The utility model efficiently solves the problems such as pure air, detergent power that existing portable air purifier is difficult to provide enough be weak, and easy to carry, uses simply, has greatly reduced the probability that people are attacked by a disease due to atmosphere pollution.

Detailed description of the invention

As shown in Fig. 1,2,4, the utility model provides a kind of portable air purifier, comprise independently a filter, face shield and for connecting the wireway of filter and face shield, filter comprises that one is provided with the housing, filter disc group 2, uviol lamp 5, air pump 7, anion generator 9 of air inlet 1 and gas outlet 8, battery 3, control circuit 6 and a switch 11 that power supply is provided at opposite side.

As Fig. 1, shown in Fig. 3, filter disc group 2 is located at air inlet 1 one sides, filter disc group 2 is successively respectively: metallic sieve 21, active carbon filter screen 22, HEPA screen pack 23 and photo-catalytic filtering screen 24, outermost metallic sieve 21 can blocks air in floating paper scrap, fallen leaves etc., the activated charcoal strainer 22 of the second layer can be removed most smell substances in air, fine particle, pernicious gas, formaldehyde, benzene and ammonia etc., what the HEPA screen pack 23 of the 3rd layer adopted in the present embodiment is the HEPA screen pack of medical grade, can reach 99.7% for 0.1 micron to the efficient of 0.3 micron particles, can effectively purify smog, dust is the pollutant such as bacterium even, what the photo-catalytic filtering screen 24 of the 4th layer adopted in this example is efficient nano photocatalyst net, the uviol lamp 5 on it and side is used in conjunction with, under the ultraviolet effect of 380nm of launching at uviol lamp 5, photocatalyst has superpower redox ability, airborne organic pollution can be resolved into carbon dioxide and water, and can destroy the cell membrane of bacterium and solidify viral protein, sterilization and deodorizing effectively.

As Figure 1 and Figure 4, the brush 91 of anion generator 9 is located at 8 places, gas outlet, anion generator 9 by brush 91 at high speed to purify after air discharge a large amount of electronics, and be combined with airborne oxygen molecule and then produce a large amount of anions and be mixed in the air after purification, and anion can make oxygen content in blood increase, enhance metabolism.Housing comprises makes that the air inlet 1 of cellular side plate, the right side flap backplate 10, the upside that are located at gas outlet 8 one sides are shielded with one's own body plate 4, downside is shielded with one's own body plate 12, front shroud 13 and back shroud, front shroud 13 is fixed by several screws, the present embodiment is 4, the object of doing is like this for convenience detach in order to change filter disc group, when maintenance, and whole housing adopts aluminium alloy or PVC material.It should be noted that, the present embodiment is made air inlet 1 cellular, is conducive to air dispersion, large area enters, and reduces air drag, can improve again the filter efficiency of filter disc group simultaneously, increases air inflow.After switch 11 is opened, under the suction of air pump 7, the air inlet 1 of air cellular from making (also can be arranged to louvered) enters, then undertaken entering in air pump 7 after multiple filtration by filter disc group 2, the air outlet 71 of air pump 7 is connected with the gas outlet 8 of housing, 8 places, gas outlet are provided with a joint (not shown), for connecting one end of wireway; Under the pressure-acting of air pump 7, the air after purification is pressed in wireway, and the other end of wireway is connected with air inlet pipe 14, and the air after purification is sent to air inlet pipe 14 and is then entered into the hollow nose support 15 of face shield by wireway.
