46a, 46b, has reached the purpose of dehumidifying and dedusting.Yet the noise of outdoor generation is divided into senior middle school's low frequency noise, after being accompanied by air and flowing into together, effect by the geometry grid ring of band V-arrangement, the geometry grid ring of being with Y shape and the sound-absorbing of set sound-absorbing back-up ring and center sound-absorbing back-up ring, constructional sound equipment retroeflection and bounce-back, rectification passage 22, when flowing into indoor high intermediate frequency noise and little by little weakened, played sound-absorbing and noise reduction again, flow into indoor air quality via room ventilation grid 10 and can obtain improving quite fully.

Because the indoor/outdoor temperature-difference in the north changes greatly and a variety of causes such as sandstorm, uses adjustable room ventilation baffle plate 11 to play and closes and conditioning chamber air draught amount outward, reduce the indoor temperature difference.Moreover when adjustable room ventilation baffle plate 11 was used to stop outdoor air intake manually, the air quantity of adjusting by adjustable room ventilation baffle plate 11 flow into indoor micro-ly.

Device is through after a while use, via dust removal filter cloth 9a, 9b, the moisture and the dust that are recovered in the negative pressure region 57 that eight one-levels in 9c and the one-level dust removal by filtration purifier 6 are filtered, and by the dust removal filter cloth 9a of two layers of cascade filtration dedusting and purifying device 7 front and back, the dust that 9b is adsorbed, also have the moisture and the dust that are reclaimed in the negative pressure region 58 of 16 cascade filtrations in the second level dedusting and purifying device 7, and be set at the adsorbed dust of dust removal filter cloth 9c behind the cascade filtration dedusting and purifying device 7, can become flexible and dismantle connecting screw rod 18 indoor, adjustable room ventilation baffle plate 11, room ventilation grid 10, dust removal filter cloth 9c, the supporting baffle 8a of each layer, 8b, 8c, 8d, 8e, cascade filtration dedusting and purifying device 7, outside rectification sleeve pipe 21 in the rectification passage 22, connecting screw rod intermediate casing 20, dust removal filter cloth 9b, first order dedusting and purifying device 6, the parts that dust removal filter cloth 9a is fixing together disassemble, can change dust removal filter cloth 9a, 9b, 9c, and water can clean after the dust in one-level dust removal by filtration purifier 6 and the cascade filtration dedusting and purifying device 7 repeatedly, installs and reuses.

Obvious technical effects of the present invention, simple, compact and reasonable for structure; Be installed in and implement the gravity-flow ventilation ventilation on the ventilating opening of residential architecture body of wall, in airtight performance lower no energy consumption in shape, and utilize indoor and outdoor atmospheric pressure difference as driving power, collect rainproof and insect protected, dehumidifying and dedusting, sound-absorbing and decrease of noise functions are integrated technology, effectively utilizing natural resources to make it to reach dehumidification rate is 50%, dust removing effects is 90%, the dedusting particle diameter is smaller or equal to 10 μ m, after noise reduction capability is 35dB, flowing into indoor air quality can be fully improved, reduce Indoor Air Pollution with outdoor Air Pollution to the harm of health, reach the building energy-conserving and environment-protective, the remarkable advantage of non-carbon-emitting.
