The passing through of this ultra -thin pair of wind wheel forced draught blower set up two wind wheels realize simultaneously about the air inlet, improved air supply efficiency for it is more frivolous that the box can be done, sets up the wind -guiding inclined plane simultaneously and carry out the wind -guiding, makes the air inlet more smooth and easy, its structure simple, and it is efficient to supply air.
Description
Technical field
This utility model belongs to technical field of electric appliances, relates to a kind of indoor scavenging machine, particularly a kind of ultra-thin pair of wind wheel pressure fan.
Background technology
Pressure fan and exhaust blower are to adopt driven by motor wind wheel to rotate, thus thinking indoor conveying fresh air or to outdoor discharge air pollution, to reach ventilation, keep the effect that room air is fresh, for varying environment occasion, different size of space, its scavenging efficiency requires different, it is thus desirable to install pressure fan or the exhaust blower of different capacity, power of motor is more big, then air draft and air-supply efficiency are more high, corresponding wind wheel is also big, and the occasion that furred ceilings are shorter is fitted up for some, blower fan causes that too greatly pressure fan cannot be installed, small-sized fan is adopted to be unable to reach again effect of effectively blowing. the small-sized pressure fan of multiple stage can only being adopted at present to blow be effective simultaneously, and the noise of pressure fan own is relatively big, multiple stage pressure fan uses the noise of generation too big simultaneously, has a strong impact on life comfortableness.
Summary of the invention
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that a kind of compact conformation, the ultra-thin pair of wind wheel pressure fan that scavenging efficiency is high.
The purpose of this utility model can be realized by following technical proposal: a kind of ultra-thin pair of wind wheel pressure fan, including casing, described casing is respectively provided on two sides with air inlet and air outlet, it is provided with ducting assembly in described casing, described ducting assembly is respectively provided on two sides with air-ducting ring, being provided with motor in described ducting assembly, described motor two is respectively equipped with wind wheel, and the outlet of described ducting assembly is connected with air outlet.
By arranging double end motor, it is respectively provided with a wind wheel in the both sides of motor so that ducting assembly can realize upper and lower air intake, improves the space availability ratio in casing, thus improve air-supply efficiency in limited space.
In ultra-thin pair of above-mentioned wind wheel pressure fan, described ducting assembly is additionally provided with the wind-guiding inclined-plane being obliquely installed near air inlet. By arranging this inclined-plane in the side near air inlet so that fresh air can be guided to air-ducting ring place by air inlet along this inclined-plane, facilitates the blower fan in air-ducting ring to blow, further increases air-supply efficiency.
In ultra-thin pair of above-mentioned wind wheel pressure fan, described ducting assembly adopts plastic material to make.The air channel that plastic material is made can be one-body molded, simplifies assembly technology, alleviates the complete machine weight of pressure fan simultaneously.
In ultra-thin pair of above-mentioned wind wheel pressure fan, described air outlet place is additionally provided with check (non-return) valve.
In ultra-thin pair of above-mentioned wind wheel pressure fan, described check (non-return) valve includes the central shaft and the non-return blade of two panels that are arranged at air outlet, described central shaft is provided with torsion spring, described torsion spring two ends act on respectively with on non-return blade, and described air outlet place is additionally provided with the step that non-return blade is stopped.
Compared with prior art, this ultra-thin pair of wind wheel pressure fan realize upper and lower air intake by arranging two wind wheels simultaneously, improve air-supply efficiency, what make that casing can do is more frivolous, arranges wind-guiding inclined-plane simultaneously and carries out wind-guiding so that air intake is more smooth and easy, its framework is simple, and air-supply efficiency is high.

Detailed description of the invention
The following is specific embodiment of the utility model and in conjunction with accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments.
As depicted in figs. 1 and 2, this ultra-thin pair of wind wheel 5 pressure fan includes casing 1, casing 1 is respectively provided on two sides with air inlet 11 and air outlet 12, ducting assembly 2 it is provided with in casing 1, ducting assembly 2 is respectively provided on two sides with air-ducting ring 3, being provided with motor 4 in ducting assembly 2, motor 4 two is respectively equipped with wind wheel 5, and the outlet of ducting assembly 2 is connected with air outlet 12. Ducting assembly 2 is additionally provided with the wind-guiding inclined-plane 21 being obliquely installed near air inlet 11 place, described ducting assembly 2 adopts plastic material to make, described air outlet 12 place is additionally provided with check (non-return) valve 6, this check (non-return) valve 6 includes the central shaft and the non-return blade of two panels that are arranged at air outlet 12, described central shaft is provided with torsion spring, described torsion spring two ends act on respectively with on non-return blade, and described air outlet 12 place is additionally provided with the step that non-return blade is stopped.
By arranging double end motor 4, it is respectively provided with a wind wheel 5 in the both sides of motor 4 so that ducting assembly 2 can realize upper and lower air intake, improves the space availability ratio in casing 1, thus improve air-supply efficiency in limited space.
