Abstract:
A new type fan air regulating device, comprising an air supply fan body (1) and a stabilizing frame (2), wherein the stabilizing frame (2) is located on the surface of the front end of the air supply fan body (1); a sliding plate (3) is arranged on a side surface of the stabilizing frame (2); a limiting mechanism (4) is arranged at the middle of an edge side of the surface of the front end of the stabilizing frame (2); the limiting mechanism (4) comprises a fixing column (8), a pull rod (9) and a first spring (10); limiting blocks (5) are respectively arranged at the top and the bottom of a side surface of the stabilizing frame (2); retracting mechanisms (6) are respectively arranged inside the top end and the bottom end of the stabilizing frame (2); and each retracting mechanism comprises a first retracting rod (61), a second retracting rod (62), a third retracting rod (63) and a second spring (64). After the sliding plate (3) slides to a proper position, the pull rod (9) is loosened, one end of the pull rod (9) inserts into a through hole in the surface of the sliding plate (3) so as to stabilize the sliding plate (3); the size of the air blowing area of the air supply fan body (1) is regulated by moving the sliding plate (3); and a dustproof mesh (72) covers the surface of the front end of the air supply fan body (1), thereby avoiding the situation where cleaning is inconvenient due to dust entering the air supply fan body (1) and accumulating on fan blades.
