The existing exhaust fan is often only provided with a single air inlet and a single air outlet, so that the installation of air inlet and outlet pipelines and the form of the air inlet are limited.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims to provide a many inlet air duct air discharge fan to prior art's is not enough to realize many inlet air duct's structural style.
The technical scheme is as follows: the utility model relates to a multi-air inlet channel exhaust fan, which comprises a fan volute, wherein a wind wheel is arranged inside the fan volute and is connected with a motor; an air outlet is formed in the side portion of the fan volute, and a gas collection box is arranged at the bottom of the fan volute; the side part of the gas collection box is provided with a plurality of air inlets; the bottom of the gas collection box is provided with a self-drooping flow guide panel, and the self-drooping flow guide panel is provided with self-drooping blades.
Preferably, a motor heat dissipation protective cover is arranged on the motor.
Preferably, the air inlet is provided with a detachable cover plate.
Preferably, the gas collection box is fixed to the bottom of the fan volute through threads.
Preferably, a sealing rubber strip is arranged between the gas collection box and the fan volute.
Preferably, the self-hanging flow guide panel is fixed to the bottom of the gas collecting box through threads.
Preferably, a sealing rubber strip is arranged between the gas collecting box and the self-hanging flow guide panel.
Preferably, the bottom edge of the gas collection box is provided with a clamping groove for fixedly mounting the exhaust fan.
The utility model discloses in, from the water conservancy diversion panel that hangs down can be according to the needs of interior decoration style, change for closing the apron.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the utility model discloses on original air discharge fan basis, set up the gas collection box, just the gas collection box sets up a plurality of air intakes to realize many inlet air channel's structural style.
(2) When the utility model works, if a plurality of air inlets of the air collection box are not used, the self-hanging blades can be automatically opened to exhaust air due to the negative pressure effect generated by the rotation of the fan; if the air inlet of the air collection box is used, the ventilation quantity passing through the air inlet and the ventilation quantity passing through the self-hanging flow guide panel can be adjusted by adjusting the opening degree of the connected air inlet, so that the multi-channel air inlet exhaust fan structure is realized.
(3) As the preferred scheme, set up removable cover on the air intake, adjust the aperture of a plurality of air intakes through adjusting removable cover.
