Abstract
The invention relates to the field of air purifiers, in particular to a fresh air type air purifier. The fresh air type air purifier comprises a fan, a shell and an air filtering unit, wherein the air filtering unit is placed in the shell; space of the inner wall of the shell is divided by the air filtering unit; a fresh air opening, an air returning opening and an air outlet are formed in the shell; the fresh air opening and the air returning opening are positioned in one side of the air filtering unit; the air outlet is positioned in the other side of the air filtering unit; and the fan is placed at the air outlet. Outdoor air can enter an indoor environment through the fresh air opening, and the oxygen content of indoor air is increased; the air filtering unit has a multilayered structure comprising an HEPA (high-efficiency particulate air) filtering layer, the service life of the HEPA filtering layer is prolonged, and the using cost is reduced; and a PM (particulate matter) 2.5 concentration detecting device and an air valve are arranged at the air outlet, the fresh air flow of the air valve is adjusted according to the concentrate of PM 2.5 of external air, and the loss of the air filtering unit is reduced.
Description
Technical field
The present invention relates to air purifier field, is especially a kind of new wind type air purifier.
Background technology
The indoor circulation wind filter type that existing common air purifier adopts carrys out airborne pollutant in filter chamber, this air purifier will shut the window to reach result of use in use, so just caused in the situation that some density of personnel are large (as classroom, hospital etc.), use existing air purifier can not guarantee indoor oxygen content, caused the sense of discomfort of indoor occupant.If adopt, introduce new wind, be also faced with at present outdoor air sometimes seriously polluted, how to guarantee service life, and how to guarantee that noise of equipment reaches service efficiency in the reasonable scope.
Summary of the invention
The object of the invention be to provide a kind of can be to the air purifier of the new wind of indoor introducing, specifically as follows by following technical scheme:
New wind type air purifier, comprise blower fan, housing and filter wind unit, described filter wind unit is placed in enclosure interior, by inner walls space partition, described housing is provided with and is positioned at fresh wind port, the return air inlet of filter wind unit one side and the air outlet that is positioned at filter wind unit opposite side, and described blower fan is placed in described air outlet place.
Described new wind type air purifier, it further designs and is, and described filter wind unit comprises pre-filtering layer, active carbon layer and the HEPA filter course being fixedly connected sequentially from fresh wind port, return air inlet one side direction air outlet one side.
Described new wind type air purifier, it further designs and is, and described fresh wind port place is provided with air-valve, and this air-valve is connected with the PM2.5 concentration detection apparatus that is arranged at fresh wind port outside.
Described new wind type air purifier, it further designs and is, and described air-valve is electric multiblade control valve.
By fresh wind port is set, that outdoor air can be entered is indoor in the present invention, has improved the oxygen content of room air; Filter wind unit is set to include the sandwich construction of HEPA filter course, in the service life of having improved HEPA filter course, has reduced use cost; By PM2.5 concentration detection apparatus and air-valve are set at air outlet, according to the new wind flow of the PM2.5 concentration adjustment air-valve of extraneous air, reduce the loss of filter wind unit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with Figure of description and embodiment, the present invention is further described:
New wind type air purifier comprises blower fan 8, housing 10 and filter wind unit 11, filter wind unit 11 is placed in enclosure interior, housing 10 inner wall spaces are cut off, housing 10 is provided with and is positioned at fresh wind port 1, the return air inlet 4 of filter wind unit 11 1 sides and the air outlet 9 that is positioned at filter wind unit 11 opposite sides, and blower fan 8 is placed in air outlet 9 places.
Filter wind unit 11 comprises pre-filtering layer 5, active carbon layer 6 and the HEPA filter course 7 being fixedly connected sequentially from fresh wind port 1, return air inlet 4 one side direction air outlet 9 one sides.
During blower fan operation, to hull outside delivery air, filter wind unit forms negative pressure near a side of air outlet, and air partly supplements negative pressure after filtering through pre-filtering layer, active carbon layer and HEPA filter course successively from fresh wind port and return air inlet, finally from air outlet output, enters indoor.
Fresh wind port place is provided with air-valve 2, and this air-valve is connected with the PM2.5 concentration detection apparatus 3 that is arranged at fresh wind port outside.Air-valve is electric multiblade control valve,
The output interface of PM2.5 concentration detection apparatus is connected with electric multiblade control valve by D/A converting circuit and power amplification circuit, regulates in real time the angle of the upper valve disc of electric multiblade control valve then the wind flow of fresh wind port to be regulated according to PM2.5 concentration.When PM2.5 concentration is high, reduce the flow of new wind, when PM2.5 concentration is low, increase new wind flow.
By fresh wind port is set, that outdoor air can be entered is indoor in the present invention, has improved the oxygen content of room air; Filter wind unit is set to include the sandwich construction of HEPA filter course, in the service life of having improved HEPA filter course, has reduced use cost; By PM2.5 concentration detection apparatus and air-valve are set at air outlet, according to the new wind flow of the PM2.5 concentration adjustment air-valve of extraneous air, reduce the loss of filter wind unit.
