Abstract

The utility model discloses a compound air purifier, belonging to the technical field of indoor air purifier. The technical key point is as follows: the compound air purifier comprises a casing which is internally provided with a ventilation machine; an air inlet is arranged on the casing wall at one side of the air inlet end of the ventilation machine; and an air outlet is arranged on the casing wall at one side of the air outlet end of the ventilation machine, wherein an air filter screen is arranged between the air inlet end of the ventilation machine and the air outlet; the air filter screen consists of a polypropylene filter screen layer, an HEPA high-efficiency filter screen layer, a cold accelerant layer and an active carbon layer that are bonded with one another; and a negative ion generator is arranged on the casing at the internal side of the air outlet. The compound air purifier has simple structure, can be used for filtering various impurities in the air, has good filtering effect and can be used for purifying indoor air.

Description

Compound air purifier

Technical field

The utility model relates to a kind of air cleaning facility, more particularly, relates in particular to a kind of compound air purifier.

Background technology

Traditional air purifier can roughly be divided into by operation principle: filter absorbent-type, electrostatic precipitation type, photocatalyst type, negative ion type and ozone type.In the air purifier of the above-mentioned type, filtering absorbent-type exists filter screen structure single, can only filter the shortcoming of the air plankton of minority, and because screen pack is too simple, filter effect to air plankton is not good enough, and the air purifier of other types, function is all single relatively, and air plankton is had stronger specific aim, and can be subjected to the influence of environment, as the photocatalyst type, general only at indoor formaldehyde, pernicious gases such as jasmine, and can be to indoor colored metope, furniture surface paint is influential, in addition, photocatalyst material needs regular hour and illumination when purifying the air of a room.These have all restricted the development of air purifier.

The utility model content

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of simple in structure, compound air purifier that can filter multiple air plankton and good filtration effect is provided.

The technical solution of the utility model is achieved in that a kind of compound air purifier, comprise casing, in casing, be provided with ventilation blower, on the enclosure wall of air intake one side of ventilation blower, be provided with fresh air inlet, on the enclosure wall of ventilation blower outlet air end one side, be provided with exhaust vent, wherein, be provided with airstrainer between described ventilation blower air intake and the fresh air inlet, described airstrainer is made of polypropylene filter mesh layer, HEPA high efficiency filter stratum reticulare, cold catalyst layer and the active carbon layer of mutual applying, also is provided with anion generator on the casing of exhaust vent inboard.

In the above-mentioned compound air purifier, described HEPA high efficiency filter stratum reticulare is folded by electret and static electrification superfine polypropylene and constitutes.

In the above-mentioned compound air purifier, described active carbon layer is the cellular particle active carbon layer, is filled in the paper wasp nest by modified activated carbon and constitutes.

After the utility model adopts said structure, by by the polypropylene filter mesh layer, HEPA high efficiency filter stratum reticulare, the four-layer structure screen pack that cold catalyst layer and active carbon layer constitute, can effectively remove indoor pollutant, as bacterium, peculiar smell, virus, flue dust, ammonia, pollen, formaldehyde, dust, hair etc., and cooperation anion generator, produce a large amount of anions, combine with airborne germ cell, the cell interior energy is shifted, structural change, cause its death, it also can make cigarette floating in the air, dirt, suction particles such as pollen gather and natural subsidence, reach the purpose that purifies air.

Description of drawings

The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.

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

Fig. 2 is the structural representation of the utility model screen pack.

Among the figure: casing 1, ventilation blower 2, fresh air inlet 3, exhaust vent 4, airstrainer 5, polypropylene filter mesh layer 5a, HEPA high efficiency filter stratum reticulare 5b, cold catalyst layer 5c, active carbon layer 5d, anion generator 6.

The specific embodiment

Consult Fig. 1, shown in Figure 2, a kind of compound air purifier of the present utility model, comprise casing 1, in casing 1, be provided with ventilation blower 2, on casing 1 wall of air intake one side of ventilation blower 2, be provided with fresh air inlet 3, on casing 1 wall of ventilation blower 2 outlet air ends one side, be provided with exhaust vent 4, between ventilation blower 2 air intakes and fresh air inlet 3, be provided with airstrainer 5, airstrainer 5 is by the polypropylene filter mesh layer 5a of mutual applying, HEPA high efficiency filter stratum reticulare 5b, cold catalyst layer 5c and active carbon layer 5d constitute, the hair of polypropylene filter mesh layer 5a in can filtered air, dirts such as big dust particle more than 20 microns, can alleviate the burden of the micro particle filtering layer 3 of its back, prolong its service life, HEPA high efficiency filter stratum reticulare 5b is the fine particle more than 0.3 micron in the filtered air effectively, to smog, pollen, bacterium, the purifying rate of virus reaches 96%, cold catalyst layer 5c can be unglazed according under the situation, remove airborne pernicious gas, active carbon layer 5d can remove airborne formaldehyde, jasmine and various peculiar smell, PARA FORMALDEHYDE PRILLS(91,95), the purifying rate of foul gas such as hydrogen sulfide reaches 95%, and it is big that it has adsorption capacity, the advantage that adsorption rate is fast.Wherein, HEPA high efficiency filter stratum reticulare 5b is folded by electret and static electrification superfine polypropylene and constitutes; Active carbon layer 5d is the cellular particle active carbon layer, is filled in the paper wasp nest by the modified activated carbon of iodine number＞950mg/g and constitutes.

During concrete the use, connect power supply, start air purifier, ventilation blower 2 and anion generator 6 start, ventilation blower 2 will suck in the fresh air inlet 3 of room air from the casing 1, make the air that contains pollutant pass through polypropylene filter mesh layer 5a in regular turn, HEPA high efficiency filter stratum reticulare 5b, cold catalyst layer 5c and active carbon layer 5d, by four layers of filter course different air pollutants are filtered, fresh air after the filtration mixes anion that anion generators 6 produce together in indoor circulation by ventilation blower 2 from the exhaust vent 4 of housing 1, air pollutants are purified, purify in the time of by dual mode, remove airborne pollutant fast.
