Abstract

The vehicle air purifier includes a casing, blower and filter screen. On the casing, there are two wind inlets on two sides, two characteristic blowers at the wind inlets to produce air flow from outside to inside and one wind outlet on the upper part; and the filter screen is set between the wind outlet and the blowers. The filter screen is in sawtooth arrangement preferably. There may be a negative ion generator set near the wind outlet. Each of the blower may consists of a centrifugal fan and a volute with wind outlet at the bottom of the casing. The two blowers set oppositely and the unique volute structure makes it possible to produce two independent circular air flows, which form one strong circular air flow with reinforced filtering and purifying effect.

Description

A kind of vehicle air purifier

Technical field

The present invention relates to a kind of air purification unit, particularly a kind of air purifier that is suitable for use in the various vehicles.

Background technology

The use of various vehicle Yin Chenei air-conditionings or because of on express highway, exercising, vehicle window must be closed, thereby in car, form the space of a relative closure, air is dirty because of the circulation of no fresh air in the car, it is dizzy that frame takes advantage of personnel therefore to occur easily, larynx is done and is waited discomfort, even occur feeling sick, carsick symptoms such as vomiting, for this reason, vehicle air purifier arises at the historic moment, as notification number is that the Chinese utility model patent " vehicle air purifier " of CN2171531Y discloses a kind of dust removal by filtration, the vehicle air purifier of effluve sterilization, it is by high-pressure discharging device, the suction air device, the peculiar smell smoke removing device, dust collector and advancing, air extractor duct is formed, wherein admission port is arranged on the front of casing, air extractor duct is arranged on the both sides of casing, the central part of casing is a high-pressure discharging device, its back is provided with the motor of band fan blade, and the air extractor duct inboard of both sides is a peculiar smell, smog is eliminated band, and the outside is for removing dust lane.Similarly, notification number is that the Chinese utility model patent " a kind of Vehicular air clean-up device " of CN2063897U also discloses a kind of dust removal by filtration, the vehicle air purifier of ultraviolet sterilization and deodour with drugs, it includes both sides and respectively has an air intake, the front has the housing of an air discharge port, two air filter units that are placed on the air intake inner side, a ultraviolet-sterilization unit that is fixed in the housing, a drug unit and an air inducing blowing unit that is fixed in the housing that is fixed in the housing, wherein the air inducing blowing unit includes a DC machine, two plastics centrifugal wind wheel and deflector shields that are installed in respectively on the same axle of the DC machine two ends.These two kinds of designs all have following common defective, the one, the two all only within it central part a blower fan is set, can't forcibly form a tangible air-flow within it, so its air inducing, air-supply poor effect; The 2nd, the both has only a flat filter element, thereby filter effect is not good.

Summary of the invention

Technical matters to be solved by this invention is to provide at above-mentioned prior art present situation that a kind of circulating current is obvious, the better air purifier of clean-up effect.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: this vehicle air purifier includes housing and is arranged on housing interior blower fan and filtering net, described housing is provided with ventilation inlet in its both sides, it is characterized in that respectively being provided with one at contiguous described two ventilation inlet places produces the blower fan of air-flow from outside to inside, and described housing is provided with air outlet at an upper portion thereof, is provided with filtering net between air outlet and blower fan.

For strengthening open area, described filtering net is arranged as good with the indentation cross section;

For further strengthening filter effect, elementary air inlet grating can be set at the ventilation inlet place of housing;

For further having sterilizing function, also can be provided with quartz burner at the bottom position of housing;

For having air refreshing function more further, also can be provided with anion generator at the wind outlet of contiguous housing;

Described blower fan can cover its outer spiral case by centrifugal blower and cover and constitute, and the ventilation inlet side of spiral case i.e. ventilation inlet with housing is relative, and the outlet of spiral case is good to be positioned at lower part of frame; The outlet of described two volute of blower produces the effect of cancelling out each other to be good towards the front side and the rear side of housing respectively to prevent the air-flow that both produce; On this basis, the air outlet that is arranged on housing top is good along the limit with limit, forward position or the back that is separately positioned on housing top, with corresponding with the outlet of two volute of blower respectively; Simultaneously, described quartz burner also can have two groups of front and back, respectively with corresponding with the outlet of two volute of blower.

Compared with prior art, the present invention is owing to be provided with two relative blower fans, and by unique scroll casing type blower fan design, make and in housing, form two strands of non-interfering circulating currents, make a concerted effort to form a stronger circulating current, thereby the circulation of air in the acceleration car, the filtering net of serrated crosssection layout has increased open area greatly simultaneously, has strengthened the filtration, purification effect.

The specific embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 2, vehicle air purifier includes housing 1 and is arranged on blower fan 3 and filtering net 7 in the housing 1, described housing 1 is provided with ventilation inlet 11 in its both sides, be provided with elementary air inlet grating 2 at ventilation inlet 11 places, and respectively be provided with one at contiguous described two ventilation inlet 11 places and produce the blower fan 3 of air-flow from outside to inside, and described housing 1 limit, forward position at an upper portion thereof and back respectively are provided with an air outlet 12 along the place, limit, between air outlet 12 and blower fan 3, be provided with filtering net 7, and these filtering net 7 indentation cross sections are arranged;

Described blower fan 3 covers its outer spiral case 32 by centrifugal blower 31 and cover and constitutes, the ventilation inlet side of spiral case 32 i.e. ventilation inlet 11 with housing is relative, the air outlet of spiral case 32 is positioned at the bottom of housing 1, and respectively towards the front side and the rear side of housing, referring to Fig. 2 (the spiral case air outlet of offside is then just in time with opposite shown in Fig. 2)
