The technological scheme of the utility model is following:
A kind of motor radiating fan; Be applied on the vacuum cleaner; Said fan comprises axial flow fan and centrifugal fan, and said axial flow fan is fixedly connected with said centrifugal fan and is positioned on the same center line, and said axial flow fan and said centrifugal fan are one-body molded.
Preferably, said axial flow fan comprises body and outer ring, and said axial flow fan air intake one side is provided with dust-proof cover, and said dust-proof cover comprises support and Air Filter, and said support is fixedly connected with said outer ring.
Preferably, each crest line place of said axial flow fan and said centrifugal fan is arcuate structure.
Preferably, the internal diameter of said support is consistent with the outside dimension of said outer ring, and said support inboard is provided with internal thread, and said collar wall is provided with the outside thread that is complementary with said internal thread.
Preferably, the internal diameter of said support is consistent with the outside dimension of said outer ring, and said support inboard is provided with at least one circle convex edge, and said collar wall is provided with the groove that is complementary with said convex edge.
The disclosed motor radiating fan of the utility model comprises axial flow fan and centrifugal fan, through axial flow fan and centrifugal fan is one-body molded; With the two effective combination, make fan both possess radiating efficiency efficiently, can commutate through centrifugal fan again; Improve the Applicable scope of fan, guarantee the radiating efficiency of motor, avoid the mistake cause thermal damage of motor; Reduce user cost; And axial flow fan and the centrifugal fan structure that is formed in one, simplify production stage, enhance productivity.

Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technological scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model discloses a kind of motor radiating fan,, enlarge the purpose of using scope to reach the raising radiating efficiency.
Like Fig. 1, shown in 2; A kind of motor radiating fan is applied on the vacuum cleaner, and this fan comprises axial flow fan 1 and centrifugal fan 2; Axial flow fan 1 is fixedly connected with centrifugal fan 2 and is positioned on the same center line, and axial flow fan 1 is one-body molded with centrifugal fan 2.Axial flow fan 1 is axially carried air-flow along it, improves the radiating efficiency of fan, after through centrifugal fan 2 axial flow is carried out 90 degree ground and reflects away; Make air-flow carry along different direction; Be adapted to the demand of different air-supply structures, enlarging application range, the damage of effectively having avoided motor overheating to cause; Improve the working life of motor, reduce use, maintenance, administration cost.Axial flow fan and the centrifugal fan structure that is formed in one simultaneously, through the employing specialized mould, but once-through integral type fan is enhanced productivity.
In addition; Axial flow fan 1 is arcuate structure with each crest line place of centrifugal fan 2; Some tiny dust granules see through probably in the dust-proof cover 3 entering fans and are prone in some corner angle corners, pile up generally speaking; Be set to arcuate structure through each crest line place, effectively avoid or reduce the accumulation of dust, guarantee fan life.
The internal diameter of support 31 is consistent with the outside dimension of outer ring 12, and through being provided with internal thread in support 31 inboards, outer ring 12 walls are provided with the outside thread that is complementary with this internal thread, spins dust-proof cover 3 and outer ring 12 fixing.
All the other are identical with embodiment 1, and difference is that the internal diameter of support 31 is consistent with the outside dimension of outer ring 12, and support 31 inboards are provided with at least one circle convex edge 13, and outer ring 12 walls are provided with the groove 14 that is complementary with convex edge 13.Effectively that dust-proof cover 3 is fixing with outer ring 12 through convex edge 13 with the clamping of groove 14; When the more dust of dust-proof cover 3 surface adhesion; For guaranteeing the cooling effectiveness of fan, need dust-proof cover 3 disassembly, cleaning or replacing, through clamping is adopted in dust-proof cover 3 and outer ring 12; Be convenient to dismounting, improve and change efficient.
Except that the foregoing description, also can be directly with dust-proof cover directly through screw on the outer ring, or adopt alternate manner to fix, as long as can realize quick detachablely, specifically depend on the circumstances, do not limit at this.
The disclosed motor radiating fan of the utility model comprises axial flow fan and centrifugal fan, through axial flow fan and centrifugal fan is one-body molded; With the two effective combination, make fan both possess radiating efficiency efficiently, have and can commutate through centrifugal fan; Improve the Applicable scope of fan, guarantee the radiating efficiency of motor, avoid the mistake cause thermal damage of motor; Reduce user cost; And axial flow fan and the centrifugal fan structure that is formed in one, simplify production stage, enhance productivity.
In addition, through dust-proof cover is set, effectively avoids or reduce dust granule to get into fan inner, the corrosion and damage that causes in the working life of improving equipment, has guaranteed the working efficiency of fan simultaneously.
More than be description,, make related domain professional and technical personnel can realize or use the utility model through above-mentioned explanation to the disclosed embodiments to the utility model embodiment.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiments shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
