Utility model content
The deficiency existing for prior art, the fresh air ventilator that provides a kind of convenient exchange core body to install is provided the purpose of this utility model.
For achieving the above object, the utility model provides following technical scheme: a kind of fresh air ventilator, comprise body, air channel and exchange core body, body one upper lateral part is provided with new wind entrance, bottom is provided with dirty wind outlet, body opposite side top is provided with dirty wind entrance, bottom is provided with new wind outlet, described internal body is provided with cavity, described cavity and air channel communicate, described exchange core body is positioned at cavity, the sidewall of described body is provided with opening, described opening and cavity communicate, described opening part is provided with the pressing plate suitable with it, described pressing plate and body removably connect by screw, the upper and lower both ends of the surface of described exchange core body are equipped with roller, the sidewall of described cavity is provided with the raceway rolling for roller.
By adopting technique scheme, in packing exchange core body into, roller in the upper and lower both ends of the surface of exchange core body is aimed to raceway, then exchange core body is pushed away in cavity, in promoting exchange core body, roller on exchange core body rolls in raceway, the frictional force that exchange core body is subject to is less, after exchange core body is pushed in cavity, cover pressing plate, make pressing plate prop up exchange core body, preventing from exchanging core body slides, and then tighten screw, in installing, can easier exchange core body be packed in cavity, and the frictional force that exchange core body is subject in the process that packs cavity into is little, wear extent is little.
The utility model is further set to: described roller is made up of elastic caoutchouc.
By adopting technique scheme, can reduce the vibrations that ventilator produces in the course of the work.
The utility model is further set to: the side of the relative opening of described exchange core body is provided with handle.
By adopting technique scheme, by handle, can very easily exchange core body be extracted out in cavity.
The utility model is further set to: described new wind porch is provided with filter.
By adopting technique scheme, enter indoor air and filter outdoor, keep the pure and fresh of air, ensure the air cleaner in flowed into chamber.
The utility model is further set to: described filter comprises roughing efficiency air filter, medium effeciency filter, high efficiency particle air filter successively; described roughing efficiency air filter is primarily efficient filter wool; medium effeciency filter is active carbon sea base cotton, and high efficiency particle air filter is HEPA screen pack.
By adopting technique scheme; primarily efficient filter wool can filter volume larger particles in air; active carbon sea base is adsorbed the particle of airborne small volume by cotton; high efficiency particle air filter; employing reaches the screen pack of HEPA standard; the efficient feature that reaches 99.7%, HEPA net for 0.1 micron and 0.3 micron is that air can pass through, but tiny particulate cannot pass through.

Detailed description of the invention
Referring to figs. 1 through Fig. 5, the utility model fresh air ventilator embodiment is described further.
A kind of fresh air ventilator, comprise body 3, air channel 5, exchange core body 8 and the outdoor air inlet communicating with new wind entrance 1, body 3 one upper lateral parts are provided with new wind entrance 1, bottom is provided with dirty wind outlet 2, body 3 opposite side tops are provided with dirty wind entrance 6, bottom is provided with new wind outlet 7, described new wind entrance 1 place is provided with filter 14, described filter 14 comprises roughing efficiency air filter 141 successively, medium effeciency filter 142, high efficiency particulate air filter 143, described roughing efficiency air filter 141 is primarily efficient filter wool, medium effeciency filter 142 is active carbon sea base cotton, high efficiency particulate air filter 143 is HEPA screen pack, described body 3 inside are provided with cavity 4, described cavity 4 and air channel 5 communicate, described exchange core body 8 is positioned at cavity 4, the sidewall of described body 3 is provided with opening 12, described opening 12 and cavity 4 communicate, described opening 12 places are provided with the pressing plate suitable with it 13, described pressing plate 13 removably connects by screw 15 with body 3, described exchange core body Shang Xia 8 both ends of the surface be equipped with elastic caoutchouc roller 9, the sidewall of described cavity 4 is provided with the raceway 10 rolling for roller 9, the side of described exchange core body 8 relative openings 12 is provided with handle 11.
