Description
Technical field
Household electrical appliance technical field is the utility model is related to, more particularly, to a kind of hair-dryer axle sleeve heat abstractor.
Background technology
Hair-dryer is mainly used in the drying and shaping of hair, but also is available for laboratory, psyciotherapy room and industrial production, art designing etc.
Aspect is made local desiccation, heating and physiotherapy and is used.Hair-dryer directly drives fan blade rotation by motor driving rotor, when fan blade revolves
When turning, air is sucked from air inlet, and the air-flow being consequently formed is blown out by mouth before air duct again;Air by when, if in the tuyere
Heating support on heating wire energization heating then blows out is hot blast, if selecting switch does not make heating wire heating power,
Blowout is cold wind, is achieved in the purpose of drying and shaping;Although hair-dryer species is a lot, structure is similar, all
It is made up of housing, handle, motor, fan blade, electric heating element, deep bead, switch, power line etc., such as such as entitled " blowing
Machine "(Publication No.:CN103717105A)Public technology shown in structure;Wherein, fan blade is often directly set on motor shaft, example
Such as entitled " fan blade and the hair-dryer with the fan blade "(Publication No.:CN104544885A)Public technology shown in fixed knot
Structure, in the disclosure technology, fan blade is set in the rotary shaft of hair-dryer intrinsic motivation to be revolved by engine driving
Turn, so as to produce wind-force.
In actual applications, most operation duration of hair-dryer is shorter, such as family expenses, though there is certain heat inside hair-dryer
Amount, but it is not enough to influence the comfort of user, the performance of internal main devices is nor affected on, can be protected after kinsfolk's use
Hold good operating condition;But for the more use environment of number of users, such as dormitory, number of users is more, several
It is continuously to run, run time length is larger, and the temperature inside hair-dryer is higher, and the heat of high temperature of motor accumulation passes through electricity
Arbor is transferred to fan blade, and for lightweight, fan blade uses plastic material mostly, is worked under long term high temperature, is easy to fatigue deformation,
Cause hair-dryer hydraulic performance decline.
The content of the invention
The utility model main purpose is to provide a kind of axle sleeve heat abstractor suitable for hair-dryer long-play.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals:Hair-dryer axle sleeve dissipates
Thermal, it includes the fan blade and motor shaft in hair-dryer housing, and the shaft end of motor shaft is fixed with radiating sleeve;The radiating
Cover and abutted in for tube structure, inner peripheral wall on the excircle of motor shaft;There is fixing hole in the middle part of fan blade, and pass through the fixing hole
It is placed on the periphery of radiating sleeve.
Fan blade is fixed on motor shaft by the utility model by copper radiating sleeve, and the heat transmission accumulated on motor shaft arrives
On radiating sleeve, externally distributed by radiating sleeve, reduce the heat being transferred on fan blade, fan blade is not likely to produce high temperature deformation and caused
Fan blade rocks the phenomenon that even fan blade comes off with respect to motor shaft, makes hair-dryer in running order for a long time, greatly improved
The stability of hair-dryer.
Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Accompanying drawing 2 is enlarged drawing at the A of accompanying drawing 1, shows a kind of structure of radiating sleeve.
Accompanying drawing 3 is another structural representation of radiating sleeve.
Wherein:1st, hair-dryer housing;2nd, fan blade;3rd, motor shaft;4th, the first flat key;5th, the second flat key;6th, radiating sleeve;7th, ring
Shape boss;8th, back-up ring;9th, platform part;10th, convex portion;11st, passage.
Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment:The utility model hair-dryer axle sleeve heat abstractor, as shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, it includes setting
In fan blade 2 and motor shaft 3 in hair-dryer housing 1, the shaft end of motor shaft 3 is fixed with radiating sleeve 6;The radiating sleeve 6 is cylinder
Structure, inner peripheral wall are abutted on the excircle of motor shaft 3;The middle part of fan blade 2 has fixing hole, and is placed on by the fixing hole scattered
On the periphery of hot jacket 6.Radiating sleeve 6 is the integrative-structure that copper or aluminum material is made, and heat transfer is quick, and radiating effect is more
It is good.
During blower operation, wind-force is sent to hair-dryer air outlet by fan blade 2, and the active force that fan blade and radiating sleeve 6 are subject to refers to
To air intake vent;Therefore, radiating sleeve 6 sets annular groove from the shaft end of motor shaft motor shaft 3, back-up ring 8, back-up ring 8 are caught in annular groove
Abut in the end of radiating sleeve 6.Back-up ring 8 bears the axial force of radiating sleeve transmission, keeps radiating sleeve during blower operation
Axial location.
Radiating sleeve 6 can have different structures, be that radiating sleeve 6 is cylinder, interior as a kind of preferably selection scheme
Keyway is set on circumference, the second flat key 5 is set on excircle;The keyway being adapted to the second flat key 5, motor are set in the fixing hole of fan blade 2
There is the first flat key 4 being adapted to the keyway of radiating sleeve 6, as shown in Figure 2 on axle 3;This structure, it is easy to make, is easy to fill
Match somebody with somebody.The end of radiating sleeve 6, which radially extends, forms annular boss 8, and annular boss 8 abuts in the sidepiece of fan blade 2;The setting of annular boss 8,
Make fan blade 2 axially more stable, be less prone to the phenomenon of axial dipole field.
Preferred version as another radiating nested structure is that radiating sleeve 6 is column, and its periphery includes the convex portion of arc
10 and platform part 9;In the circumference of radiating sleeve 6, convex portion 10 and platform part 9 are in be staggered;The fixing hole of fan blade 2 is circular hole,
Inner peripheral wall is formed with the periphery of convex portion 10 and is fixedly connected;Inner peripheral wall, convex portion 10 and the platform part 9 of fan blade 2 wrap into air-flow stream
Logical passage 11;As shown in Figure 3.Passage 11 improves the contact area of radiating sleeve and air, can accelerate radiating sleeve and air
Heat exchange, while reduce the contact area of radiating sleeve and fan blade, reduce further the temperature of fan blade.
The setting of the top of convex portion 10 is raised, in the inner peripheral wall of the embedded fan blade 2 of projection;Projection can be from two sides of axial and circumferential
Upwards, it is spacing to fan blade and lock, fan blade and relative movement of the radiating sleeve on this two direction are prevented, improves the stabilization of complete machine
Property.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses
Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with the power
The protection domain that profit requires is defined.
