The utility model discloses, can solve the weak point among the prior art, can the noise reduction.
Description
Technical field
This utility model relates to Fan Equipment field, especially relates to a kind of fan blade on axial flow blower.
Background technology
Blower fan generally comprises fan blade and air-ducting ring, and air-ducting ring is used for fixing fan blade, and just wind produced by fan blade carries outward by air-ducting ring, plays certain assosting effect；So while air-ducting ring plays fixing fan blade, also function to certain auxiliary wind-guiding, and be typically all between existing air-ducting ring and fan blade and be fixed by bolt or screw, additionally when fan blade is under long-term operating at a high speed, compare thin with only adding by screw between air-ducting ring to be solidly connected and be easy to breakage, particularly at the position connected, cause fan blade to loosen and then produce the biggest noise, so the applicant proposes improvement with regard to this, prestige can solve problem present in these existing products.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, it is provided that a kind of fan blade on axial flow blower, it is possible to solve weak point of the prior art, can reduce noise.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
A kind of fan blade on axial flow blower, including installation end, the outer wall at described installation end is formed around the fan blade arranged at equal intervals, it is characterised in that: described fan blade includes blade, one end of described blade is fixed with described installation end, and the other end end of described blade is provided with reinforcement；Forming toothed edge on the side side of described blade, the opposite side side of described blade forms arc point limit；It is needle-like in the longitudinal cross-section of described blade, increases successively to described arc point limit thickness from described toothed edge；It is provided with wind guide tank in described blade upper and lower surface.
Doing this utility model further preferably, the bottom surface of described wind guide tank is arcuate groove, and one end is stub end, and the other end is little head end, and described stub end is positioned at described toothed edge, and described little head end is positioned at described arc point limit.
This utility model is done further preferably, between described installation end and described fan blade, be provided with reinforcement.
Doing this utility model further preferably, described wind guide tank has 3.
Doing this utility model further preferably, the outer surface of described blade is provided with noise reduction layer.
Doing this utility model further preferably, the outer surface of described blade is provided with antirust coat.
Compared with prior art this utility model is reached to provide the benefit that:
Fan blade described in this utility model includes that blade, one end of described blade are fixed with described installation end, and the other end end of described blade is provided with reinforcement；Forming toothed edge on the side side of described blade, the opposite side side of described blade forms arc point limit；It is needle-like in the longitudinal cross-section of described blade, increases successively to described arc point limit thickness from described toothed edge；It is provided with wind guide tank in described blade upper and lower surface；Wind is cut by this utility model by toothed edge, reduce the wind resistance to blade, and then reduction noise, the wind of fan blade both sides is owing to easily blocking up after toothed edge effect simultaneously, cause producing noise in blade both sides, so this utility model carries out wind-guiding by the wind guide tank arranged, and then reduce noise.It addition, wind-guiding effect can also be played in the arc point limit formed on this utility model fan blade, the wind of both sides utilizes the arc-shaped side of both sides, arc point limit carry out wind-guiding, and then reduces noise.
It follows that this utility model can solve the problem that weak point of the prior art, noise can be reduced.
