Description

Air purger for vehicle

The utility model belongs to the passenger-cargo chamber air-treatment of vehicle technical field.

Before the utility model, the Vehicular air clean-up device often adopts modes such as electrostatic precipitation, active carbon layer deodour by adsorber, ultraviolet sterilization.As the electrostatic Vehicular air defecator of the smart device (strain) in the Japanese Northeast first design portion, the PT150 type air purifier of U.S. TECTRONIC company and the automobile air cleaner (clear 60-132616) etc. of Japanese Matsushita Electric Industrial company.Electrostatic precipitation has dust removing effects preferably to following dust of micron and the lower air of dust content, but require when using automobile storage battery voltage is risen to high pressure about 10 kilovolts, this will manufacture to equipment and bring certain difficulty, and may bring adverse influence with safety to the work of people and Che Nei electronic machine.Active carbon has adsorption preferably to multiple gases; but influence because of the long-pending size of its deodour by adsorber ability receptor 1 activity carbon surface; institute thinks its deodour by adsorber ability of raising; activated carbon adsorption layer must be done very closely knit; this will increase greatly air by the time resistance; and when dealing with improperly, micro activated carbon particle also falls into air easily, makes through concentration of floating in the air of dedusting.Ultraviolet sterilization can reduce bacterial concentration in the air, and its bactericidal effect depends primarily on ultraviolet irradiation intensity and irradiation time.Because the electric power and the installing space that can provide on the automobile are limited, are difficult to guarantee enough big exposure intensity and sufficiently long irradiation time, so the simple air sterilization effect that reaches satisfied of being difficult to by ultraviolet sterilization.For the deficiency that overcomes air cleaning in the prior art, sterilization, deodorization device has designed a kind of new Vehicular air clean-up device.

The purpose of this utility model provides a kind of be used for air cleaning in the car compartment, degerming, deodorization processing, sends the Vehicular air clean-up device of fragrant fresh air.Its volume is little, light weight, safe in utilization, efficient rapidly, is a kind of multifunctional vehicle air purification unit.

Main points of the present utility model are: the Vehicular air clean-up device includes both sides and has the housing that air intake, front have 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, one is fixed on the drug unit in the housing and is fixed on the interior air inducing blowing unit of housing.Air unit after filtration can intercept big foreign matter, removals such as paper scrap big particulate, filtering floating dust below 10 microns and the parts of fine bacteria microorganism more than 10 microns that is mingled with in the air successively.Airguide air discharge port direction after the air inducing blowing unit will filter through ultraviolet irradiation and after with sterilization, deodorization, fragrant drug treating, is sent fragrant fresh air by air outlet.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is that the Vehicular air clean-up device is overlooked cross-sectional view.A metal shell (3) oad is 280 * 220 * 140 millimeters, metal shell each side have an air intake (1), the front has an air discharge port (2).On two air intake inner sides, respectively place an air filter unit (4).The micronic filter (10) that the rough filter (9) that air filter unit is become by a metal lath (8) of outside in placing successively, poly-ester fibres felt and polypropylene non-woven fabric filter material are made is formed.Metal lath can intercept big foreign matter such as the paper scrap that is mingled with in the air and enter in the housing, and rough filter can be removed in the air big particulate more than 10 microns, and the thickness of used poly-ester fibres felt is 4 millimeters, can be set in the metal sheet screen frame.But floating dust and the parts of fine bacteria microorganism of micronic filter filtering below 10 microns, used polypropylene non-woven fabric filter material are made the corrugated of reciprocal folding and are done in advance and add Electrostatic Treatment, and its thickness is 0.4 millimeter, can be set in the metal sheet frame.Rough filter and micronic filter were changed once about general half a year.On the middle position of housing bottom surface, be fixed with an air inducing blowing unit (7).It includes the DC machine (17) of 30 watts of power, at the same axle of DC machine two ends a plastics centrifugal wind wheel (18) is housed respectively, also has a metal deflector shield (19) that is fixed on the approximate involute shape on the housing and power supply wiring socket (20), speed change resistance (21), Gear-shift switch (22) in addition.Utilize the automobile storage battery power supply, DC machine drives two centrifugal wind wheels and rotates, and at first air is introduced housing from the both sides air intake, is sent to the air outlet direction through the air filter unit filtered air behind the deflector shield change of direction.Can obtain two kinds of motor speeds of height by speed change resistance and Gear-shift switch.Air after the filtration passes through ultraviolet-sterilization unit (5) sterilization again.The ultraviolet-sterilization unit pack contains 7 watts of ultraviolet germicidal lamps of a ZYX7 type (11) and an inverter plate (13).Fig. 2 is mounted in the saturated push-pull circuit schematic diagram of common cascode on the inverter plate, mainly comprises transistor Q ₁, Q ₂, speed-up capacitor C ₂, the protection capacitor C ₁, filter capacitor C, sensitizing tube Q ₃, light-emitting diode Q ₄Form.Utilize the automobile storage battery power supply, provide ultraviolet germicidal lamp required trigger voltage 1000V, operating voltage 280V.An other anti-dazzle device (12) that is fixed in the housing is used for preventing that UV light from shining outside the housing.Also fix a drug unit (6) in housing, it includes plastic casing (15) and Polyurethane foam that soaked medicine (16) that is placed in the box that both sides have medicine sending-out hole (14).It is sterilization, the deodorization aromatic of main body that medicine can be selected hydrogen peroxide and lemon for use.Forwards flow air is taken said medicine out of, is dispersed into from sending-out hole and carries out air disinfection, deodorization, fragrance processing the air, sends fragrant fresh air from air discharge port at last.

Vehicular air purifying device of the present utility model is installed in the car compartment, utilizes automobile storage battery to make power supply, and air is carried out dedusting, degerming, deodorization processing, sends fragrant fresh air. This device purified treatment ability of air is per hour 200 cubic metres, 6 kilograms of gross masses, and power consumption is 30 watts, and it is many to have function, and quality is light, uses safety, rapidly efficient advantage, also applicable to fields such as train box, ward, bedrooms.
