Abstract
The utility model discloses a fresh air ventilator. According to the technical scheme, a fresh air opening is square, sliding grooves which are formed in the flowing direction of air of the fresh air opening are formed in the two sides of the fresh air opening, and inserting plates matched with the sliding grooves are arranged in the sliding grooves. The sides, opposite to outlets of the sliding grooves, are respectively provided with a dustproof part which can be folded in the direction of the fresh air opening, the two dustproof parts form a dustproof cover, and the dustproof parts are hinged to the inserting plates. Stopping blocks which prevent the inserting plates from sliding out from the sliding grooves are arranged on the edges, opposite to the sliding grooves, of an outer shell, and one ends of the stopping blocks are movably riveted with the outer shell. When the fresh air ventilator is not used for a long time, the inserting plates can be drawn out, then the dustproof parts are folded, the two dustproof parts form a dustproof structure, and a good dustproof effect is achieved. The stopping blocks can prevent the inserting plates from moving out from the sliding grooves. When the fresh air ventilator needs to be used, the stopping blocks are moved away, then the dustproof parts are folded, the surfaces of the dustproof parts are made to be flush with the surfaces of the inserting plates, and thus the inserting plates and the dustproof parts can be both stored in the sliding grooves. The overall appearance of the fresh air ventilator is not influenced, and operation is easy and quick.

Utility model content
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of can fine dustproof fresh air ventilator in the time not using for a long time.
For achieving the above object, the utility model provides following technical scheme: a kind of fresh air ventilator, comprise housing, the both sides of housing are separately installed with air inlet, exhaust outlet, return air inlet and fresh wind port, in described housing, be provided with exchange core body, motor exhaust and new wind turbine, four faces of described exchange core body respectively with air inlet, exhaust outlet, return air inlet is corresponding with fresh wind port, described fresh wind port is square, the both sides of described fresh wind port are equipped with the chute arranging along fresh wind port gas flow direction, in described chute, be equipped with the plate being mated, the relative chute of described plate exports a side and is equipped with the dustproof portion that can turn down towards fresh wind port direction, described two dustproof portions form dust cap, described dustproof portion and plate are hinged, the edge of the relative chute of described housing is equipped with the block that stops that plate skids off from chute, all rivet with housing is movable described block one end.
By adopting technique scheme, in the time not using fresh air ventilator for a long time, can extract the plate of both sides out, turn down again two dustproof portions, two dustproof portions form dustproof construction, can play good dustproof effect, block can prevent that plate from shifting out from chute, make dust cap more stable, dust-proof effect is better, in the time that needs use fresh air ventilator, remove block, turn down again two dustproof portions, dustproof portion surface is flushed with plate surface, so just plate and dustproof portion all can be received in chute, do not affect the overall appearance of fresh air ventilator, and simple and quick.
The utility model is further set to: the upper surface of described dustproof portion is all established projection.
By adopting technique scheme, in the time of the dustproof portion of turnover, hand can turn down the portion of preventing dust by projection, more laborsaving like this convenience.
The utility model is further set to: the opposite side of the relative plate of described dustproof portion is equipped with the magnet of strip.
By adopting technique scheme, in the time that the turnover of two dustproof portions is formed to dustproof construction, two dustproof portions can inhale by magnet fixing mutually, and stablizing effect is better.
The utility model is further set to: described air inlet place is provided with filter; described filter comprises roughing efficiency air filter, medium effeciency filter, high efficiency particulate air filter; described roughing efficiency air filter is primarily efficient filter wool, and medium effeciency filter is active carbon sea base cotton, and high efficiency particulate air filter is HEPA screen pack.
By adopting technique scheme; primarily efficient filter wool filters volume larger particles in air; active carbon sea base is adsorbed the particle of small volume in air by cotton; high efficiency particulate air filter adopts the screen pack that reaches HEPA standard; reach 99.7% for the efficient of 0.1 micron and 0.3 micron; the feature of HEPA net is that air can pass through, but tiny particulate cannot pass through.
