Description
Technical field
The present invention relates to garden instrument field, the mute air channel structure of especially a kind of hair dryer.
Background technique
As in greenbelt waste paper, fallen leaves, cleaning get up it is very difficult, be always sanitationman very headache the problem of.
Hair dryer wind-force is powerful, need to only blow a few minutes in opposite greenbelt, sundries is just blown out on greenbelt to road to clean.
It is noisy noise that this powerful hair dryer is often adjoint, after carefully studying noise source, it has been found that
The noise in air duct is generated by 3 lumpy structures.
1, the generation of noise is mainly uneven caused in machine air duct, in recess after air impact to shell
Birdie occurs, and air duct is done and puts down and can not reach；2, traditional blade wheel structure is used in air duct, the air being inhaled into can be straight
It connects vertical direction toward impact and generates biggish noise to fan blade face, also the air duct of some machines is curved, but final air can also hang down
Directly strike impeller；3, in general, the flabellum of electric fan is more, and air-supply effect is better, although will increase load, no
It crosses, flabellum is more, " wind " can be cut to obtain more fritter, keep the wind produced by boasting softer, and muting function is more preferable, but due to impeller
It is integral structure, considers for demoulding, what will not be designed between blade is more close.
Summary of the invention
The purpose of the present invention is being directed to the existing above problem, a kind of mute air channel structure of hair dryer is provided.
Object of the invention can be realized by the following technical scheme: a kind of mute air channel structure of hair dryer, including wind
Road chamber, air inlet and air outlet are equipped with impeller strut rail in the chamber of air duct, are equipped with motor impeller and rotate, which is characterized in that
Software piece is equipped in the chamber of air duct, software piece is covered on the cavity wall of air duct, will fill and lead up the embossed area of air duct cavity wall
Domain.Mainly solve first defect of background technique.
The software on piece is equipped with the porous of sound-absorbing.
The software piece includes sponge sheet.
Pod is equipped in front of the impeller, which is horn-like, the big mouth direction air inlet side of pod, water conservancy diversion
The big mouth of cover is the square configuration with chamfering, and impeller center is equipped with the taper lid of frustum cone structure to air inlet side, and taper lid is complete
Portion or part are located in pod, and pod medial surface and taper outer side of lid side will enter the wind multi-angle remission.Mainly solve background
Second defect of technology.
The impeller includes several blade unit, and blade unit includes splicing main body and tilting blade, blade and spelling
Main body integrated molding is connect, the two sides for splicing main body are plane, and mutually adjoint patch, each main body of splicing surround the plane of contiguous concatenation main body
One annulus and it is intermediate be it is hollow, the upper and lower position for splicing main body is equipped with groove, and upper and lower position is formed after splicing main body splicing
Annular groove, is inserted in the concentric dome of restriction effect in annular groove, blade along annulus array axis, in the axial direction of annulus,
Adjacent front vane lower end and rear blade upper end local stacking.Solve the third defect of background technique.
The top edge of the blade and lower edge are S-shaped.
The annulus that the splicing main body surrounds has up-small and down-big taper, and the big end cover of the taper lid is in annulus
On small end face, taper lid large end face is not more than small end face diameter.In order to cooperate the wind-guiding of taper lid.
For the motor set in the blower inlet casing of a closed warhead form, motor shaft is pierced by blower inlet casing and connection leaf
Wheel, the tip of blower inlet casing is towards air outlet.
Compared with prior art, the present invention is designed in the structure for using sound-isolating sponge, makes the bump of air duct cavity wall
Position is filled and led up, and birdie is not likely to produce.Secondly, increasing taper shut off and the increase technology of blade quantity makes air frontal impact
Reduce, reduces noise.

Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Shown in Fig. 1-Fig. 2, the present invention is located at the inside of hair dryer, including air duct chamber 3, air inlet 1 and air outlet 8, air inlet
Mouthful 1 is designed as that Open Side Down, influence minimum when holding in this way to operator.Sponge sheet 2 is equipped in air duct chamber 3, sponge sheet 2 will
It is filled and led up in air duct chamber 3, eliminates relief region in air duct chamber 3, will not thus generate birdie.Since sponge sheet 2 is self-contained more
Hole, therefore there are also the effects of sound-absorbing for sponge sheet 2.
Equipped with 6 strut rail of impeller in air duct chamber 3, it is equipped with 5 impeller 6 of motor and rotates, be equipped with and lead in front of the impeller 6
Stream cover 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 the rectangular of chamfering
Shape.6 center of impeller is equipped with the taper lid 9 of frustum cone structure, and in pod 4, taper lid 9 is located in impeller 9 part of taper lid
Heart position, taper lid 9 is all or part is located in pod, and it is anti-to enter the wind multi-angle outside pod medial surface and taper lid 9
It penetrates.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.
