In a kind of above-mentioned wind scooper, the conical baffle lower end is located in interconnecting piece.The lower end of conical baffle
There are when certain distance in interconnecting piece and with fan outlet, the diversion effect of conical baffle is preferable.
It is circumferentially spaced on the medial surface in the cover body lower end portion to be equipped with multiple and blower in a kind of above-mentioned wind scooper
The mounting portion of shell connection, the mounting portion pass through the connecting rod and blower that are radially arranged centered on the central axes of cover
Shell is connected.Mounting portion and the connection type being attached by connecting rod can reduce the connection knot of cover and Blower Housing
Influence of the structure to air draft is conducive to improve ventilation efficiency.
In a kind of above-mentioned wind scooper, there are six the mounting portions, and circular array is uniformly fixed on cover body lower end portion
Medial surface on.The mounting portion of circular array setting can be improved the stability of wind scooper installation, reduce the generation of noise.
Compared with the prior art, the utility model has prominent and beneficial technical effects that:
It can first be struck in conical baffle when utility model works from the air-flow that blower comes out, by leading for deflector
Stream is discharged downwards along the inner wall of cover, and the air-flow for avoiding blower from coming out vertically strikes on the top plate of cover, reduces air-flow and hits
Beat the noise that cover top plate generates；Ascending air rises along conical baffle inside simultaneously, and down current is in the cover of outer
Wall decline, avoids interfering for ascending air and down current, is conducive to improve exhaust effect.
