Description
Technical field
The present invention relates to field of power tools, especially a kind of impeller composite structure.
Background technique
It is noisy noise that powerful hair dryer is often adjoint, after carefully studying noise source, it has been found that air duct
Noise part with impeller have substantial connection.
In general, the flabellum of electric fan is more, and air-supply effect is better, although will increase load, but, flabellum
It is more, " wind " can be cut to obtain more fritter, keep the wind produced by boasting softer, muting function is more preferable, but since impeller is one
Structure considers that will not be designed between blade is more close for demoulding.Secondly traditional blade wheel structure is used in air duct, is inhaled
The air entered can direct vertical direction toward impact to fan blade face generate biggish noise, also the air duct of some machines is curved, but most
Whole air can also vertical direction toward impact to impeller.
Summary of the invention
The purpose of the present invention is being directed to the existing above problem, a kind of impeller composite structure is provided.
Object of the invention can be realized by the following technical scheme: a kind of impeller composite structure, including several blades
Unit, each blade unit circumferential direction split are an impeller, and impeller strut rail is in the chamber of air duct, which is characterized in that blade unit includes
Splice main body and tilting blade, the two sides for splicing main body are plane, and the plane of contiguous concatenation main body mutually lead by adjoint patch, each splicing
Body surround an annulus and it is intermediate be it is hollow, the upper and lower position for splicing main body is equipped with groove, upper bottom after splicing main body splicing
It sets to form annular groove, the concentric dome of restriction effect is inserted in annular groove；Splice rear blade along the array axis of annulus, in circle
In the axial direction of ring, adjacent front vane lower end and rear blade upper end local stacking.
The top edge of blade and lower edge are S-shaped.
Be equipped with pod in air duct, pod be it is horn-like, the big mouth of pod is towards air inlet side, and impeller center is to air inlet
Side is equipped with the taper lid of frustum cone structure, and taper lid is all or part is located in pod, outside pod medial surface and taper lid
Side will enter the wind multi-angle remission.
The annulus that the splicing main body surrounds has up-small and down-big taper.
For the big end cover of the taper lid on the small end face of annulus, taper lid large end face is not more than small end face diameter.
The blade and splicing main body is integrally formed.
Compared with prior art, the present invention can increase the blade quantity on impeller, can be while increasing suction air volume
" wind " cuts to obtain more fritter, and muting function is more preferable, and impeller and pod inclined-plane can rebound to enter the wind and form vortex, and air is made not hang down
It is straight to hit the blade surfaces of revolution, and reduce noise.
Detailed description of the invention
Fig. 1 is position view of the invention.

Fig. 3 is blade wheel structure schematic diagram.
Fig. 4 is impeller cut-away illustration.
In figure, 1 air inlet；2 sponge sheets；3 air duct chambers；4 pods；5 motors；6 impellers；7 blower inlet casings；8 air outlets；9 cones
Degree lid；10 concentric domes；11 blades；12 splicing main bodys；13 annular grooves
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
The inside of hair dryer in Fig. 1-Fig. 2, including air duct chamber 3, air inlet 1 and air outlet 8, air inlet 1 are designed as being open
Downwards, influence when holding in this way to operator is minimum.Sponge sheet 2 is equipped in air duct chamber 3, sponge sheet 2 will be filled out in air duct chamber 3
It is flat, relief region in air duct chamber 3 is eliminated, birdie will not be thus generated.Since sponge sheet 2 is self-contained porous, sponge
There are also the effects of sound-absorbing for piece 2.
6 strut rail of impeller of the invention is equipped with 5 impeller 6 of motor and rotates, set in front of the impeller 6 in air duct chamber 3
Have pod 4, the pod 4 be it is horn-like, for the big mouth of pod 4 towards air inlet 1, the big mouth of pod 4 is with chamfering
Square configuration.6 center of impeller is equipped with the taper lid 9 of frustum cone structure, and for 9 part of taper lid in pod 4, taper lid 9 is located at leaf
Center is taken turns, taper lid 9 is all or part is located in pod, will enter the wind outside pod medial surface and taper lid 9 polygonal
Degree reflection.Eddy flow can be generated, gas out of plumb is made to pour blade 11.
Shown in Fig. 3-Fig. 4, impeller 6 includes several blade unit, and blade unit includes splicing main body 12 and blade 11, leaf
Piece 11 and splicing main body 12 are integrally formed, and the two sides of splicing main body 12 are plane, the mutual adjoint patch of the plane of contiguous concatenation main body 12,
Each splicing main body 12 surround an annulus and it is intermediate be it is hollow, annulus has taper to cooperate taper lid 9.Splice main body 12
Upper and lower position be equipped with groove, upper and lower position forms annular groove 13 after splicing main body 12 is spliced, and sets concentric dome on annular groove 13
10.Then 5 axis of motor passes through concentric dome 10 and taper lid 9, and nut is set on 5 axis of motor by concentric dome 10 and taper lid 9
It compresses, drop out blade unit will not.The big end cover of the taper lid 9 is on the small end face of annulus, and 9 large end face of taper lid is not
Greater than small end face diameter, guarantee has taper in the same direction.The small end face of taper lid 9 is towards 1 direction of air inlet.
Blade 11 is located at the outside of contiguous concatenation main body 12, blade 11 along annulus array axis, with the axial for base of annulus
Quasi- direction, then the upper and lower end of blade 11 and the upper and lower endlap of left and right adjacent blades 11 add.The top edge of blade 11 and lower edge
It is S-shaped.The above structure increases intake, and using not having to consider the problems of to demould after blade unit, therefore blade 11 can be with
As S-shaped, also can 11 partial stack of adjacent blades, increase blade 11 quantity.
In the blower inlet casing 7 of a closed warhead form, 5 axis of motor is pierced by blower inlet casing 7 and connects described 5 sets of motor
Impeller 6, the tip of blower inlet casing 7 is towards air outlet 8.Therefore the streamline that 8 air of air outlet forms " several " word is entered from impeller 6,
Transversal shock is greatly reduced, and can increase intake.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
