Embodiment
Below by the mode of execution of specific instantiation explanation the utility model, those skilled in the art can be understood the advantage and the effect of the utility model easily by the content that this specification is set forth.
Notice; The appended graphic structure that illustrates of this specification, ratio, size etc.; The content of all only setting forth in order to the cooperation specification for those skilled in the art's understanding and reading, is not in order to limit the enforceable qualifications of the utility model; Event is the technical essential meaning of tool not; The adjustment of the modification of any structure, the change of proportionate relationship or size is not influencing under effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model sets forth and get in the scope that can contain.Simultaneously; That is quoted in this specification reaches terms such as " second " like " preceding ", " back ", " side ", " periphery ", " cover cap ", " end ", " horn-like ", " first "; Also be merely be convenient to narrate clear, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment; Under no essence change technology contents, when also being regarded as the enforceable category of the utility model.
As shown in Figure 2, it is the sectional view of the fan assembly of the utility model.
The fan assembly of the utility model comprises fan base 2; It comprises annular solid 20 and establishes the first annular retaining edge 21 and the second annular retaining edge 22 respectively at annular solid 20 two ends; Annular solid 20 has the through hole 200 that runs through; And the through hole 200 of annular solid 20 has uniform diameter, and the first annular retaining edge 21 has the first relative opening end 21a and the second opening end 21b.The second annular retaining edge 22 has the first relative opening end 22a and the second opening end 22b.The first opening end 22a of the first opening end 21a of the first annular retaining edge 21 and the second annular retaining edge 22 is the two ends of connecting through hole 200 respectively; The diameter of one end of connected this through hole 200 of diameter of the first opening end 21a of the first annular retaining edge 21 is identical; The diameter of one end of connected this through hole 200 of diameter of the first opening end 22a of the second annular retaining edge 22 is identical; And the diameter of the first opening end 21a of the first annular retaining edge 21 is identical with the diameter of the first opening end 22a of the second annular retaining edge 22; And the first annular retaining edge 21 and the second annular retaining edge 22 from its first opening end 21a and 22a to its second opening end 21b and 22b its diameter that increases, constitute trumpet-shaped body.
In addition, fan base 2 also is formed with framework 23, and this framework 23 has opposite first 23a and second surface 23b and runs through first surface 23a and the perforate 230 of second surface 23b.The second opening end 21b of the first annular retaining edge 21 connects the second surface 23b of framework 23, and the perforate 230 of its through hole 200 corresponding frameworks 23.
In addition; Fan assembly also comprises flabellum 3; It is placed in the through hole 200 of annular solid 20; As shown in Figure 2, flabellum 3 do not protrude in the second opening end 21b of the first annular retaining edge 21 and the second annular retaining edge 22 the second opening end 22b, or do not protrude in the first opening end 21a and the second annular first opening end 22a that keeps off edge 22 of the first annular retaining edge 21.
Hold above-mentioned; Because flabellum 3 does not protrude in the second opening end 21b and the 22b or the first opening end 21a and the 22a of the first annular retaining edge 21 and the second annular retaining edge 22; Thereby air-flow is down guided from the top when passing through hole 200 when flabellum 3; Most of air-flows all can pass through via flabellum 3, and then can collect mass air flow, to promote the usefulness of whole fan.
Cooperate and consult Fig. 3, it is the three-dimensional exploded view of the fan assembly of the utility model.Fan assembly also comprises rack 4, motor bracket 5 and motor 6 except fan base as shown in Figure 22 and flabellum 3.
As shown in Figure 3, the periphery of rack 4 has second engagement portion 40, and its netting twine that can be rack 4 is terminal.And framework 23 first surface 23a as shown in Figure 2 have one expose this perforate 230 alcove 231, the sidewall 232 of alcove 231 is provided with first engagement portion 233, for example hole.Rack 4 is sticked in first engagement portion 233 of framework 23 with second engagement portion 40, with cover cap alcove 231.
Following table is in order to the comparison of the actual test result of the fan assembly that shows the utility model and existing fan assembly:
It is as shown in the table; The motor of the utility model fan assembly amasss thick (silicon steel plate thickness; The thick then motor driven power that heals is bigger) lacked about 20% than the motor that has fan assembly now is long-pending thick; But how the air quantity of air draft and air draught has distinguished 8.1% and 21.7%, and the power consumption of air draft and air draught has also lacked 24% and 21.99% respectively.
In sum; Because the fan base of the fan assembly of the utility model has annular solid and is located at first annular solid and second annular solid of the first relative opening end of having of annular solid two ends and second opening end respectively; This first annular solid is connected the two ends of this annular solid and expands its diameter to its second opening end with its first opening end with second annular solid; So wind-force in the ability active set; Promoting the suction/air draft effect of fan, and can be with reaching preferable suction/air draft effect than the motor of low power consumption power, and then reach power saving and the high effect of usefulness.
The foregoing description is only in order to the principle and the effect thereof of illustrative the utility model, but not is used to limit the utility model.Any those skilled in the art all can make amendment to the foregoing description under the spirit and category of the utility model.So the rights protection scope of the utility model, should be listed like claims.
