Abstract

The present invention relates to an air purifier for a vehicle, which comprises a shell (1), a fan (3) which is arranged in the shell, and a filtering net (7), wherein both sides of the shell (1) are provided with air inlet ports (11). The present invention is characterized in that fans (3) which generate airflow from inside to outside are respectively arranged in the position which is close to two air inlet ports (11), and the upper part of the shell (1) is provided with an air outlet port (12). The filtering net (7) is arranged between the air outlet port (12) and the fans (3). The filtering net (7) had better be arranged in a saw tooth-shaped cross section. A negative ion generator (6) can also be arranged in the position of air inlet close to the shell. The fan (3) can be composed of a centrifugal fan (31) and a spiral shell (32) which is covered on the outside of the centrifugal fan (31), and an air outlet port of the spiral shell (32) is positioned on the lower part of the shell. The air outlet port of the spiral shell respectively face to the front side and the rear side of the shell. Because two opposite fans are arranged by the present invention, two strands circulating airflow without mutual interference are led to form in the shell through the unique design of the spiral shell type fan to form stronger circulating airflow by means of resultant force. Consequently, the circulation of air in a vehicle is accelerated, and simultaneously, the filtering net which is arranged according to the saw tooth-shaped cross section adds filtering areas, and enhances filtering and purifying effects.

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, between air outlet and blower fan, be provided with filtering net, described blower fan covers its outer spiral case by centrifugal blower and cover and constitutes, the ventilation inlet side of spiral case i.e. ventilation inlet with housing is relative, the outlet of spiral case is positioned at lower part of frame, and the outlet of described two volute of blower is respectively towards the front side and the rear side of housing.

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;

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.
