Abstract
The invention relates to an air filter used in a ventilating fan. A filtering body comprises a double-layer metal mesh and a dust layer sandwiched between layers of the metal mesh, and the filtering body is fixedly installed on the ventilating fan; the center of the filtering body protrudes outwards, deashing back flushing devices are uniformly distributed on the periphery of the filtering body, and the deashing back flushing devices comprise back flushing pipes and nozzles; and a pressure sensor is installed inside one side of the filtering body, an electromagnetic valve, an air pump, a prompt warning lamp and an integrated circuit are installed on the outer side of the filtering body, and the integrated circuit is arranged in a dust cover in a wrapping manner. Moisture, oil and impurities in air are filtered by V-shaped glass fiber filter paper, and relatively dry air is retained; a bamboo charcoal adsorption layer absorbs and decomposes harmful substances, dust and peculiar smell by utilizing a super-strong adsorption function of the bamboo charcoal adsorption layer; the back flushing devices carry out dust cleaning treatment on the filter; therefore, the filtering effect of the air filter is effectively improved, and the service life of the air filter is also prolonged simultaneously.
Description
Technical field
The present invention relates to a kind of air cleaning unit, the air cleaner particularly 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 family is all provided with ventilation fan, and the outside of most of ventilation fan is provided with air inlet louvers, in order to dust-proof.But along with the progress of society, the raising of people's Living Water product, air pollution is also increasing the weight of.Only use shutter dust-proof, effect is not very well, and the micronic dust in air inevitably enters into indoor through shutter, and outdoor oil smoke etc. also can flow into indoor with air.Long-time use, needs shutter to unload cleaning, and handling cleaning is very inconvenient.
Summary of the invention
For the problems referred to above, the invention provides the air cleaner in a kind of ventilation fan.
Realize technical scheme of the present invention as follows:
An air cleaner in ventilation fan, comprises filtering body, and described filtering body comprises double-level-metal net and is folded in one deck dust layer between metal net layer, and described filtering body is fixedly mounted on ventilation fan; Filtering body center outwardly convex, is evenly equipped with deashing back-blowing device in the surrounding of filtering body, and described deashing back-blowing device includes anti-blowpipe and nozzle; Be provided with pressure sensor in the inside, side of filtering body, 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, outer makes 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.
Sealing ring is provided with between described anti-blowpipe and nozzle.
The invention has the beneficial effects as follows: moisture, oil content, magazine in V-type glass fiber filter paper filtered air, retain and hand over dry air; The adsorption function that bamboo Charcoal Adsorption layer utilizes it superpower, absorbs harmful substance, micronic dust, peculiar smell, decomposes; Back-blowing device carries out dirt process clearly to filter; These all effectively improve the filter effect of air cleaner, also improve the service life of air cleaner simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention is arranged on ventilation fan;
Fig. 2 is A-A face of the present invention schematic diagram;
Fig. 3 is filtering body of the present invention;
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 fiber filter paper, and 14 is the fine adsorption layer of bamboo charcoal.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described;
Shown in Fig. 1-Fig. 3, the air cleaner in a kind of ventilation fan, comprises filtering body, and described filtering body comprises double-level-metal net 3 and is folded in one deck dust layer 4 between wire netting 3 layers, and described filtering body is fixedly mounted on ventilation fan 1; Filtering body center outwardly convex, is evenly equipped with deashing back-blowing device in the surrounding of filtering body, and described deashing back-blowing device includes anti-blowpipe 11 and nozzle 10; Be provided with pressure sensor 7 in the inside, side of filtering body, 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, outer makes 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 threaded, facilitate the replacement of nozzle 10.
Sealing ring 12 is provided with between described anti-blowpipe 11 and nozzle 10.
Moisture, oil content, magazine in V-type glass fiber filter paper 13 filtered air, retain and hand over dry air; The adsorption function that bamboo Charcoal Adsorption layer 14 utilizes it superpower, absorbs harmful substance, micronic dust, peculiar smell, decomposes.Outdoor air goes out shutter 2 and enters, and through the effect of wire netting 3, glass fiber 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 when reaching the preset value of pressure sensor 7, signal is passed to integrated circuit and sent prompting warning by pressure sensor 7; After ventilation fan 1 quits work, artificial closedown points out warning, and integrated circuit will transmit deashing signal, and magnetic valve 9 and air pump 5 work, and spray gas and carry out deashing to filtering body in nozzle 10.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
