Abstract

The utility model discloses an air purifier with a good filter effect and high safety factor. The air purifier comprises a box body and a filter passage in the box body, wherein a plasma filter, a ULPA filter, a filtering layer consisting of pure diatom, a photocatalyst device for sterilizing and filtering pollutants and a blower for air exhaust, which are sequentially arranged in the filter passage from the front to the back, wherein the photocatalyst device comprises a titanium dioxide photocatalyst layer and at least one ultraviolet light source. When the air purifier is in use, the blower sucks air outside the box body into the filter passage, then the air sequentially passes through the plasma filter, the ULPA filter, the filtering layer and the photocatalyst device for adsorption, filtering, sterilization and other purification functions, and finally, clean air is discharged through the blower. According to the utility model, particles, smog, granules and the like in air are filtered through the plasma filter and the ULPA filter, and then pollutants, bacteria, dust and harmful gases in the air are filtered through the pure diatom filtering layer and the photocatalyst device, so that the purpose of air purification is achieved.

Description

A kind of air purifier

Technical field

The utility model relates to field of Environment Protection, is specifically related to a kind of air purifier for filtered air.

Background technology

The frequent movable indoor environment of the mankind is standing various pollutions at present, and they have had influence on the every aspect of our life.Some pollution can make children dizzy, the symptom such as feel sick, thereby have a strong impact on people's operating efficiency.Especially organic contamination and germ contamination have produced serious restriction to the raising of quality of life.The technology such as existing filtration, absorption, negative oxygen ion and ozone, are all difficult to lasting and effectively purifying organic polluted.And the technology such as thimerosal, ultraviolet lamp sterilization, ozone sterilization all exist the side effect of human body and the low problem of germicidal efficiency.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of good filtration effect, air purifier that safety coefficient is high.

The utility model solves the technical scheme that its technical problem adopts:

An air purifier, comprises casing and the filtration channel that is positioned at casing, in filtration channel, is provided with successively from front to back:

Plasma filter for filtering contaminants;

Ulpa filter for filter particulates, smog and microorganism;

For filtering contaminants, bacterium, dust and by the pure filter course forming of diatom;

For the photocatalyst device of sterilization and filtering contaminants, described photocatalyst device comprises photocatalyst of titanium dioxide layer and at least one ultraviolet light source;

For the blower fan of bleeding.

In the utility model, described photocatalyst of titanium dioxide layer periphery is provided with four ultraviolet light sources.

In the utility model, described plasma filter, ulpa filter, filter course and photocatalyst device are tabular.

In the utility model, interval 2 ~ 10mm between described plasma filter and ulpa filter.

In the utility model, described ulpa filter is close to filter course.

In the utility model, interval 10 ~ 20mm between described filter course and photocatalyst device.

The beneficial effects of the utility model are: in use, blower fan sucks filtration channel by watertight aircase external body, then successively by plasma filter, ulpa filter, filter course and photocatalyst device to air adsorb, the catharsis such as filtration, sterilization, then by blower fan by clean Bas Discharged.The utility model is by the particulate in plasma filter and ulpa filter filtered air, smog, particle etc., then by the pure filter course of diatom and photocatalyst device filtering contaminants, bacterium, dust and pernicious gas, thereby reach the object purifying air.This clarifier can be widely used in the places such as household, meeting-place, court, suitable for large-scale promotion.

Accompanying drawing explanation

Below in conjunction with drawings and embodiments, the utility model is further illustrated:

Fig. 1 is structural representation of the present utility model.

The specific embodiment

With reference to Fig. 1, a kind of good filtration effect provided by the utility model, the air purifier that safety coefficient is high, comprise casing and the filtration channel that is positioned at casing, is provided with successively from front to back: for the plasma filter 1 of filtering contaminants in filtration channel; Ulpa filter 2 for filter particulates, smog and microorganism; For filtering contaminants, bacterium, dust, and by the pure filter course forming 3 of diatom; For the photocatalyst device of sterilization and filtering contaminants, described photocatalyst device comprises photocatalyst of titanium dioxide layer 4 and four ultraviolet light sources 5; For the blower fan 6 of bleeding.In the present embodiment, described plasma filter 1, ulpa filter 2, filter course 3 and photocatalyst device are tabular, and the placement that is parallel to each other.

Described plasma filter 1, photocatalyst device are all connected with a controller, by controller, open or close plasma filter 1 and photocatalyst device, and can control the quantity that ultraviolet light source 5 is opened, thus reach different clean-up effects, be applicable to various places.After opening plasma filter 1, not only reach better bactericidal effect, and make in air, with electron ion, to make air quality better.

In order to reach better filter effect, interval 2 ~ 10mm between described plasma filter 1 and ulpa filter 2, optimum is 9mm, makes it have enough distances and filters; Described ulpa filter 2 is close to filter course 3; Interval 10 ~ 20mm between described filter course 3 and photocatalyst device, optimum is 15mm, before contact photocatalyst of titanium dioxide layer 4, by ultraviolet light source 5, carries out sterilizing in advance.

In the utility model, described diatom is pure to be contained in a screen frame, and diatom is pure is graininess, and the diameter of each particle is 3 ~ 5mm.Diatom is pure has extremely strong physical absorption performance and ion-exchange performance, thereby can effectively adsorb and eliminate airborne pernicious gas.It can full-automatic, round-the-clock long-acting lasting absorption and decontamination chamber in, the pernicious gas such as the formaldehyde in Che Nei and other enclosure spaces, benzene, dimethylbenzene, TVOC, effectively avoided adsorbing the generation of saturated and secondary pollution problems simultaneously.

The foregoing is only preferential embodiment of the present utility model, as long as within the technical scheme that realizes the utility model object with basic identical means all belongs to protection domain of the present utility model.
