Description

A kind of vehicular air purifier
Technical field
The present invention relates to technical field of air purification, be specifically related to a kind of vehicular air purifier.
Background technology
In recent years, along with popularizing of self-propelled vehicle, increasing family starts to have various self-propelled vehicle.But along with the high speed of self-propelled vehicle is popularized, the problem of in-vehicle air pollution is more and more appeared in one's mind in face of customer.
In-vehicle air pollution refers to the situation of the air quality difference that automotive interior causes due to reasons such as stuffy, car body finishings.In-vehicle air pollution source is mainly from car body itself, decorative material etc., and wherein the toxic substance pollution effect such as formaldehyde, dimethylbenzene, benzene is the most serious.In September, 2012, a " healthy automobile examining report " shows that 11 sections of mainstream car design may exist carcinogenic risk, and carcinogen contains carcinogenic substance from in-car air quality.
The domestic technical standard for in-vehicle air pollution, only has " in manned vehicle Air Quality Evaluation guide " that in March, 2012 formally implements." in manned vehicle Air Quality Evaluation guide " is according to the kind of volatile organic matter in air in car, source and the analysis to the boiling characteristics of the main interior material of vehicle own, determine 8 kinds mainly by control material, define the concentration requirement of benzene in air in car, toluene, dimethylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde, acrolein.
But, " in manned vehicle Air Quality Evaluation guide " be a Technical specifications just, and permissive legislation.And relative to too low American-European standard, have employed the upper limit level of room air standard.According to the environment inside car standard that Germany works out, content of formaldehyde can not more than 0.08 milligram/cubic meter, and China's standard is can not more than 0.1 milligram/cubic meter.
At present, for the purification of air in car, most customer puts the porous mass such as active carbon, pomelo peel, the characteristic of the porous of this kind of matter utilization own car is built-in, can adsorb the partial aromatic hydrocarbon in car in air, but it can not purify and point takes off described aromatic pollution.
Separately there is some consumers, in car, put the volatile matters such as perfume, with the fragrance atmosphere of volatile matter itself, cover the sharp aroma of in-vehicle exposure thing.But these class methods do not reduce the concentration of benzene in air, toluene, dimethylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde, acrolein in car, on the contrary because the volatile matters such as the perfume that adopts contain ethanol, methyl alcohol etc., air in car is caused and again pollutes.
Summary of the invention
The object of the invention is to propose a kind of in-car air purifier, it first carries out catalysis to air in car, benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, acrolein are decomposed or oxidation, then enters follow-up adsorbed layer, carry out adsorbing and sterilization.
For reaching this object, the present invention by the following technical solutions:
A kind of vehicular air purifier, comprise housing, centrifugal blower, catalytic member, filtration adsorption element, wherein centrifugal blower, catalytic member, filtration adsorption element are arranged in the cavity of housing, and centrifugal blower is arranged on the middle part of housing hollow; The both sides of housing offer air outlet respectively, and the side, bottom of housing is provided with power interface; Housing upper end offers several air intake vent, and the below of air intake vent is provided with catalytic member, and the below of catalytic member is provided with filtration adsorption element.
