Description

Air blower structure

Technical field

The utility model provides a kind of air blower structure, comprise the main chamber seat being located at hair-dryer enclosure interior, enter vane and heat insulation inner bag, make somebody a mere figurehead at main chamber seat inside center axis and an assembling base is set, this assembling base is that a circuit arranges chamber forward, inner stator towards the rear then for fixing for brushless motor internal stator and power supply circuit assembling thereof arranges chamber, and the outside of stator is the vaned rotation outer rotor of a tool, this built on stilts assembling base outer wall arranged be then the individual flow deflectors of all-in-one-piece majority both being connected between the seat inwall of main chamber, after the seat of main chamber can clamping one hollow enter vane, front then can the heat insulation inner bag of clamping one hollow.

Background technology

The technical application of known hair-dryer is novel nothing more than utilizing motor driving fan blade to suck air-flow by hair-dryer air intake vent, thermal current blowout is formed through electrically-heated coil heating, visible in these known techniques utility models, each portion spare part is not integrated, cause spare part many and dispersion, therefore to produce in assembling not only cost high and time-consumingly to take a lot of work, relative product effect is low, economic benefit is also low.

Simultaneously, in utility model in early days, the motor of hair-dryer all adopts carbon brush motor, and carbon brush motor is limited to owing to being subject to the abrasion life-span restriction of carbon brush, so in rotation setting hour (as about 500 hours running lives of d.c. motor, alternating current motor is about 1000-2000 hour running life) after, namely cannot operate because of carbon brush abrasion, cause the inconvenience in actual use and maintain and replace loss.Therefore, relevant utility model to change with brushless motor to replace life-span shorter carbon brush motor, makes to be able to the service life of hair-dryer longer (as 5000-20000 hour).But because the traditional concept of known hair-dryer internal structure affects, cause the air supply direction of blower fan blade and internal gas flow channel cannot reach linearity without the smoothness obstructed, also result in larger blower fan and the noise of air-flow.

Therefore, how to simplify hair-dryer internal structure and integrate spare part, how reducing costs and promotes to produce and imitate, then by industry urgency technical application new bottleneck to be broken through and target.

Utility model content

The utility model air blower structure is for comprising main chamber seat, entering vane and heat insulation inner bag, and its utility model object is: the service life promoting hair-dryer; Simplify the structure of hair-dryer; Make the air-flow Vomitory of hair-dryer smooth and easy; That reduces hair-dryer produces cost, and promotes product effect; The Practical Benefit of effective lifting hair-dryer and economic worth.

In order to achieve the above object, the utility model provides a kind of air blower structure, comprise be located at hair-dryer enclosure interior main chamber seat, enter vane and heat insulation inner bag, wherein main chamber seat inside center axis is maked somebody a mere figurehead and is arranged an assembling base fixed for the assembling of brushless motor inner stator, the outside of inner stator is a built on stilts rotatable outer rotor, the internal face of outer rotor is provided with magnet, and outer wall is one-body molded has multiple blade, in built on stilts setting assembling base outer wall be then all-in-one-piece most flow deflectors both being connected between the seat inwall of main chamber.

Further, the assembling base that wherein this main chamber seat inside center axis makes somebody a mere figurehead setting is that a circuit arranges chamber forward, and the inner stator towards the rear then for fixing for brushless motor inner stator and power supply circuit assembling thereof arranges chamber.

Further, wherein this main chamber seat rear clamping one hollow enter vane.

Further, the heat insulation inner bag of wherein this seat front, main chamber then clamping one hollow.

Be arranged at hair-dryer inside by this structure utility model, must make that hair-dryer reaches long service life, structure is simplified, air-flow channel is smooth and easy, cost is low and novelty that benefit promotes and progressive.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.

Refer to this case air blower structure embodiment shown in graphic middle Fig. 1 to Fig. 2, comprise the main chamber seat 1 being located at hair-dryer enclosure interior, enter vane 2 and heat insulation inner bag 3, wherein as shown in Fig. 3 to Fig. 6 and Fig. 7 to Fig. 9, make somebody a mere figurehead at main chamber seat 1 inside center axis and an assembling base 11 is set, this assembling base 11 is that a circuit arranges chamber 111 forward, inner stator towards the rear then for fixing for brushless motor inner stator 4 and power supply circuit assembling thereof arranges chamber 112, and the outside of inner stator 4 is a built on stilts and rotatable outer rotor 5, the outer wall of this outer rotor 5 is one-body molded has multiple blade 51, the internal face of outer rotor 5 is provided with the magnet 52 with the effect of inner stator 4 coil, in built on stilts setting assembling base 11 outer wall be then most the flow deflectors 12 of all-in-one-piece both being connected between seat 1 inwall of main chamber, after main chamber seat 1 can clamping one hollow enter vane 2, seat 1 front, main chamber then can the heat insulation inner bag 3 of clamping one hollow.

Be arranged at hair-dryer enclosure interior by this structure utility model, following actual benefit must be reached and promote:

(1) rotation motor set by seat inside, main chamber is Brushless DC motor, therefore there is not the problem of carbon brush abrasion restricted lifetime, so long service life.

(2) by conjunction with motor inner stator assembling base with most flow deflectors and main chamber seat one-body molded, therefore really reach simplifying of structure.

(3) enter by rear the air-flow that vane enters, after the blade suction that outer rotor of motor is wholely set, directly send into heat insulation inner bag by the guiding of flow deflector with straight line path and blown out by hair-dryer air outlet, therefore whole inlet air and air-out path very unobstructed, direct, so air channel intercepts few, effectively noise can be reduced.

(4) main chamber seat is one-body molded, and after the seat of main chamber can clamping one hollow enter vane, front then can the heat insulation inner bag of clamping, and therefore assembling is rapidly, to produce effect fast, and the cost that really can reach time and labour saving reduces.

(5) owing to becoming instinct effectively to reduce, and produce effect soon, therefore can effectively promote industry utilization benefit and economic worth.

(6) comprehensively above-mentioned, really can promote the novel novelty of hair-dryer technical application and practical improvement.

The above embodiment is only for absolutely proving the preferred embodiment that the utility model is lifted, and protection domain of the present utility model is not limited thereto.The equivalent alternative or conversion that those skilled in the art do on the utility model basis, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
