Description

A kind of air purifier

Technical field

This utility model relates to gas cleaning plant, specifically a kind of air purifier.

Background technology

In the environment for human survival, have all kinds of harmful gass and tool volatile injurant matter, as waste gas of newly-decorated house, some chemical enterprise emission etc., in public indoor as hospital, station etc. exists each viroid and antibacterial especially in the air.Therefore, air purifier miscellaneous just arises at the historic moment, it mainly can reduce 2 big classes: 1, the air purifier that is used of HEPA air filting material and activated carbon, HEPA high density filter material can filter and adsorb the pollutant more than 0.3 micron, and activated carbon then plays adsorption to abnormal flavour, harmful gas.But there is following shortcoming in this scheme: after using certain hour, air filting material must in time be changed, otherwise, not only can not purify air, can cause secondary pollution to air on the contrary, and the absorption that is replaced the air filting material of various pathogenic bacterias, harmful gas can pollute environment.2, the air purifier that photocatalyst airstrainer and Burdick lamp are used, photocatalyst is under the irradiation of ultraviolet, produce strong catalytic degradation function, the toxic and harmful in the air of degrading effectively, kill various bacteria virus, the effect of air cleaning depends on intensity and air and the photocatalyst surface area contacted size of ultraviolet to the photocatalyst irradiation, for the surface area that makes airstrainer is realized maximization, the shape of drainage screen is processed into honeycomb shape usually or other are similar to the shape of honeycomb effect, and being coated with photocatalyst material thereon, Burdick lamp shines on the drainage screen.But there is following shortcoming in this scheme: ultraviolet illumination is mapped on the airstrainer, having part light can see through honeycomb hole is wasted, and behind the use certain hour, airstrainer can gather dust, covered photocatalyst, clean-up effect is reduced greatly, because the boring ratio of cellular drainage screen is less, be difficult to dust is cleaned up, therefore safeguard cumbersome.

Summary of the invention

The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art part, and a kind of air purifier is provided, and it is simple in structure, and is easy to use, can be used for purifying air, and kill bacteria is improved people's living environment.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of air purifier, comprise cavity, and its cavity inner wall is coated with the titanium dioxide active material layer, is provided with Burdick lamp in the cavity; Cavity one side is provided with exhaust fan, and the side that cavity is relative with exhaust fan is provided with air intake vent.

In technique scheme, described air intake vent place is provided with air quality Intelligent Measurement control unit, this unit is made up of single-chip microcomputer, Detection of Air Quality monitoring induction module and control module, the input of described single-chip microcomputer links to each other with the outfan of Detection of Air Quality monitoring induction module, the outfan of single-chip microcomputer links to each other with control module, and the outfan of control module links to each other with the on and off switch of Burdick lamp and exhaust fan respectively.

In technique scheme, the titanium dioxide active material particle degree that described cavity inner wall covers is smaller or equal to 10 nanometers.

This utility model compared with prior art has the following advantages: 1, simple in structure, easily manufactured.2, Environmental Safety, titanium dioxide active material (being photocatalyst) itself is a kind of material of food stage, the air that shone through Burdick lamp does not have any injury to the person yet.3, purification efficiency height, Burdick lamp also can effectively be killed airborne pathogenic bacteria when the triggering photocatalyst works.4, energy-conservation, the working time of the present utility model is controlled automatically according to air quality, to greatest extent saves energy.

The specific embodiment

The utility model will be further described below in conjunction with drawings and Examples.

As shown in Figure 1, a kind of air purifier of this utility model comprises cavity 1, and it is photocatalyst that its cavity 1 inwall is coated with the titanium dioxide active material layer, is provided with Burdick lamp 2 in the cavity 1; Cavity 1 one sides are provided with exhaust fan 3, and cavity 1 and exhaust fan 3 relative sides are provided with air intake vent 4.This utility model is to utilize 2 pairs of photocatalysts of Burdick lamp to shine, make photocatalyst produce strong catalytic degradation function, fast with the air cleaning in the cavity 1, ultraviolet also can be apace with airborne killing bacteria in the cavity 1 simultaneously, exhaust fan 3 is discharged the air that has purified in the cavity 1, simultaneously cavity 1 outer air is sucked cavity 1 and purifies.So constantly circulation is until with the whole spatial air cleaning outside the cavity 1.

In the above-described embodiments, the titanium dioxide active material particle degree of described cavity 1 inwall covering is smaller or equal to 10 nanometers.

In the above-described embodiments, described air intake vent 4 places are provided with air quality Intelligent Measurement control unit 5.As shown in Figure 2, this unit is made up of single-chip microcomputer a, Detection of Air Quality monitoring induction module b and control module c, the effect of Detection of Air Quality monitoring induction module b is that the concentration with contained pollutant in the air converts digital signal transfers to and handles for single-chip microcomputer a, single-chip microcomputer a sends control signal according to the pollution level of air, makes control module c control exhaust fan 3 and Burdick lamp 2 start or stop work.This utility model embodiment has adopted common chip AT89C52 as single-chip microcomputer a, and the signal output part of Detection of Air Quality monitoring induction module b is connected with 23,24 pins of AT89C52 chip, and the control signal of control module c is picked out by pin 14.

In the above-described embodiments, Burdick lamp 2 can send wavelength be 250 nanometers to the ultraviolet between 400 nanometers, the working power of Burdick lamp 2 is controlled by the control module c in the air quality Intelligent Measurement control unit 5.

In the above-described embodiments, exhaust fan 3 is the 220V radiator fan, and its working power is controlled by the control module c in the air quality Intelligent Measurement control unit 5.

The operation principle of this utility model embodiment is: when needs use air purifier, connect its power supply, single-chip microcomputer a outputs signal to control module c control exhaust fan 3 work certain hours and plays pre-heat effect, simultaneously because the work of exhaust fan 3, attract air in depurator cavity 1, to assemble, the data of Detection of Air Quality monitoring induction module b are more reliable, when detecting air pollution arranged, control module c then starts Burdick lamp 2 and works with exhaust fan 3, and ceaselessly reads the contamination data signal from the outfan of Detection of Air Quality monitoring induction module b.There is pollution then to control exhaust fan 3 and Burdick lamp 2 works on, do not pollute and then control exhaust fan 3 and Burdick lamp 2 quits work.Go round and begin again and constantly circulate, reach the purpose that starts or stops according to air quality control depurator automatically.
