Abstract
The utility model relates to an air filter used in an air exchange fan. A filter main body comprises double layers of metal nets and a dustproof layer sandwiched between the metal net layers, wherein the filter main body is fixedly arranged on the air exchange fan; the center of the filter main body is outwards bulged; ash-cleaning back-flushing devices are uniformly distributed at the periphery of the filter main body; each of the ash-cleaning back-flushing devices comprises a back-flushing tube and a spray nozzle; a pressure sensor is arranged inside one side of the filter main body; a solenoid valve, a gas pump, an instruction warning lamp and an integrated circuit are arranged outside the filter main body; the integrated circuit is covered in a dustproof cover. V-shaped glass fiber filter paper is used for filtering moisture, oil and impurities in the air, and retaining dried air. A bamboo charcoal adsorption layer is used for absorbing and decomposing harmful substances, dust and peculiar smell by virtue of the super-strong adsorption function thereof; the back-flushing device is used for carrying out dust-clearing treatment on the filter. And therefore, filter effect of the air filter is effectively improved, and service life of the air filter is also prolonged.
Description
Technical field
The utility model relates to a kind of air cleaning unit, the air cleaner of particularly using in a kind of ventilation fan.
Background technology
Room ventilation deficiency will cause room air pollution more and more serious, affects the healthy of people.In order to make room air keep pure and fresh, most families are all provided with ventilation fan, and the outside of most of ventilation fans is provided with air inlet louvers, in order to dustproof.But, along with social progress, the raising of people's Living Water product, air pollution is also increasing the weight of.Only use shutter dustproof, effect is not fine, and airborne micronic dust inevitably can enter into indoor, outdoor oil smoke etc. through shutter also can be indoor with flowing into of air.Long-time use, need to unload cleaning by shutter, and handling are cleaned very inconvenient.
Utility model content
For the problems referred to above, the utility model provides the air cleaner of using in a kind of ventilation fan.
Realize the technical solution of the utility model as follows:
An air cleaner of using in ventilation fan, comprises filtration body, and described filtration body comprises double-level-metal net and be folded in one deck dust layer between metal net layer, and described filtration body is fixedly mounted on ventilation fan; Filter body center outwardly convex, be evenly equipped with deashing back-blowing device in the surrounding of filtering body, described deashing back-blowing device includes anti-blowpipe and nozzle; In a side inside of filtering body, pressure sensor is installed, outside is provided with magnetic valve, air pump, prompting emergency warning lamp and integrated circuit, and described integrated circuit is coated in dust cap.
Described dust layer comprises two-layer, and skin is made glass fiber filter paper for glass fiber material, and internal layer is bamboo Charcoal Adsorption layer.
Glass fiber filter paper in described dust layer is V-shaped folding.
Described anti-blowpipe and nozzle are movable connection.
Between described anti-blowpipe and nozzle, be provided with sealing ring.
The beneficial effects of the utility model are: moisture, oil content, magazine in V-type glass fiber filter paper filtered air, retain and hand over dry air; Bamboo Charcoal Adsorption layer utilizes its superpower adsorption function, and harmful substance, micronic dust, peculiar smell are absorbed, decomposed; Back-blowing device carries out dirt processing clearly to filter; These have all effectively improved the filter effect of air cleaner, the service life of also having improved air cleaner simultaneously.
Brief description of the drawings
Fig. 1 is that the utility model is arranged on the structural representation on ventilation fan;
Fig. 2 is the utility model A-A face schematic diagram;
Fig. 3 is filtration body of the present utility model;
In accompanying drawing, 1 is ventilation fan, and 2 is shutter, and 3 is wire netting, and 4 is dust layer, 5 is air pump, and 6 is dust cap, and 7 is pressure sensor, and 8 is prompting emergency warning lamp, and 9 is magnetic valve, 10 is nozzle, and 11 is anti-blowpipe, 12 sealing rings, and 13 is glass fibre filter paper, 14 is the fine adsorption layer of bamboo charcoal.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described;
Shown in Fig. 1-Fig. 3, the air cleaner of using in a kind of ventilation fan, comprises filtration body, and described filtration body comprises double-level-metal net 3 and be folded in one deck dust layer 4 between 3 layers of wire nettings, and described filtration body is fixedly mounted on ventilation fan 1; Filter body center outwardly convex, be evenly equipped with deashing back-blowing device in the surrounding of filtering body, described deashing back-blowing device includes anti-blowpipe 11 and nozzle 10; In a side inside of filtering body, pressure sensor 7 is installed, outside is provided with magnetic valve 9, air pump 5, prompting emergency warning lamp 8 and integrated circuit, and described integrated circuit is coated in dust cap 6.
Described dust layer 4 comprises two-layer, and skin is made glass fiber filter paper 13 for glass fiber material, and internal layer is bamboo Charcoal Adsorption layer 14.
Glass fiber filter paper 13 in described dust layer 4 is V-shaped folding.
Described anti-blowpipe 11 and nozzle 10 are movable connection, can be to be threaded, and facilitate the replacement of nozzle 10.
Between described anti-blowpipe 11 and nozzle 10, be provided with sealing ring 12.
Moisture, oil content, magazine in V-type glass fiber filter paper 13 filtered airs, retain and hand over dry air; Bamboo Charcoal Adsorption layer 14 utilizes its superpower adsorption function, and harmful substance, micronic dust, peculiar smell are absorbed, decomposed.Outdoor air goes out shutter 2 and enters, and through the effect of wire netting 3, glass fibre filter paper 13, the fine adsorption layer 14 of bamboo charcoal, is purified.
Filter uses the dust that can deposit for a long time, and ventilation flow will reduce, and while reaching the preset value of pressure sensor 7, pressure sensor 7 is passed to integrated circuit by signal and sent prompting warning; After ventilation fan 1 quits work, people is for closing prompting warning, and integrated circuit will transmit deashing signal, and magnetic valve 9 is worked with air pump 5, sprays gas and carry out deashing to filtering body in nozzle 10.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model openly in scope; still can do some corrections or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
