Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1 Fig. 2 and Fig. 3, a kind of cooling fan of motor, including motor housing 1 and electric machine main shaft 2 are please referred to, outside motor The surface of shell 1 has been bolted silencer cover 12, and the inner surface of silencer cover 12 has been bolted funnel air hose 9, electricity The left end surface of owner's axis 2 is fixed with the first positioning round frame 10, and the surface of the first positioning round frame 10 is symmetrically welded with flabellum 11, the The inside of funnel air hose 9 is arranged in flabellum 11 for one setting circle frame 10, and the surface portion of electric machine main shaft 2 is fixed with ventilation base 3, The centre of surface position of ventilation base 3 is provided with the second positioning round frame 6, is fixed with electric machine main shaft 2 on the inside of the second positioning round frame 6, The surface of ventilation base 3 is evenly arranged with the first air inlet 4 and the second air inlet 5, and the second air inlet 5 goes out with funnel air hose 9 Air port is corresponding, and the side of ventilation base 3 is welded with rotary table air hose 7, and the inner wall surface of rotary table air hose 7 is provided with tilting piece of blowing 8, tilting piece 8 of blowing to be set to the first air inlet 4 corresponding.

Fig. 1 and Fig. 4 is please referred to, the surface and side of silencer cover 12 are provided with bloop 15, make an uproar by the mitigation of bloop 15 Sound unofficial biography, the surface of silencer cover 12 have been bolted filter mantle 17, and the surface of filter mantle 17 is provided with installing port 20, installation Mouthfuls 20 inside is provided with filter screen 19, and the inside of filter mantle 17 is provided with silencing cotton 16, the inner wall surface of funnel air hose 9 and tiltedly The surface for setting piece 8 of blowing is provided with silencing cotton 16, is absorbed by silencing cotton 16 to noise.

Referring to Fig. 1, the surface of silencer cover 12 is provided with gas outlet 13, the inside of gas outlet 13 is equipped with Air Filter 14, Prevent dust from entering.

When the utility model is specifically implemented: because rotary table air hose 7 is fixed on 2 surface of electric machine main shaft by ventilation base 3 And flabellum 11 is fixed on the left-hand face of electric machine main shaft 2 by the first positioning round frame 10, so solving cooling blower revolving speed Problem, when motor operating, electric machine main shaft 2 just will drive the tilting rotation of piece 8 of blowing of rotary table air hose 7 and its inner wall surface setting Turn, the tilting wind-force that the rotation of piece 8 generates of blowing is right along 3 surface the first air inlet 4 of ventilation base is passed through between tilting piece 8 of blowing Motor carries out blow-through cooling, because flabellum 11 and electric machine main shaft 2 be in the inside of funnel air hose 9, when electric machine main shaft 2 drives flabellum 11 When rotation, the wind of generation can be side-blown to motor one along the inside of funnel air hose 9, because of the shape feature of funnel air hose 9, fan The wind-force that 11 leaves generate is able to accelerate then to cool down to motor surface by the second air inlet 5 on the inside of funnel air hose 9, because For flabellum 11 generate wind accelerate by funnel air hose 9 and cooperate tilting piece 8 of blowing to generate wind to solve cooling effect undesirable Problem；The noise that electric machine main shaft 2 drives rotary table air hose 7 and the rotation of flabellum 11 to generate, disappears because the design principle of silencer cover 12 is same Soundboard design principle is identical, is all according to Principles of Acoustics by allowing material itself to become porous structure, in this way when sound is transferred to When plate surface, they can be entered in hole, then be cut out, so the bloop 15 by 12 surface of silencer cover can It is effective to mitigate noise unofficial biography, and pass through 17 inner wall surface of filter mantle, 9 inner wall surface of funnel air hose and tilting 8 surface of piece of blowing The silencing cotton 16 of setting can effectively absorb the noise of generation, when reaching mitigation flabellum 11 and the rotation of rotary table air hose 7 The effect of the noise of generation.
