Problems solved by technology

In practice, it was found that similar figure 1 When the centrifugal fan blade is driven by a 19,000rpm AC motor at high speed, the fan blade will be deformed due to the stress of the air flow, reducing the compression ratio
[0010] figure 2 Due to the increased number of blades and the balance between the air inlet area and the stiffness of the blades, the centrifugal fan blade design shown in the figure will generate greater noise due to the increase in air volume when applied to a high-speed AC motor, and its lifespan will also be shortened. relatively short
And this kind of centrifugal blade design is also difficult to match the shape of the hair dryer on the market
[0011] image 3 The shown design of axial fan blades requires large air inlet size and low compression ratio, which cannot meet the high performance, large air volume and high wind speed requirements of professional hair stylists

Embodiment 1

[0029] The present embodiment is a kind of fan blade of centrifugal hair dryer, such as Figure 4 As shown in -5, it includes a fixed base 1 and blades arranged circumferentially on the top surface of the fixed base 1; the blades include long blades 2 and short blades 3 shorter than the long blades, and the short blades 3 are set on the outer edge of the top surface of the fixed base.

[0030] The increase of blades will reduce the pressure difference between the windward side and the leeward side of a single blade in the hair dryer blade, and increase the slip factor (Slipfactor) of the hair dryer blade, thereby improving the compression ratio and wind speed output of the hair dryer blade . However, in the novel hair dryer fan blade in this embodiment, the blade combination design of the long blade and the short blade whose length is shorter than the long blade and is arranged on the outer edge of the top surface of the fixed base can increase the number of blades and achiev...

Embodiment 2

[0038] This embodiment 2 is an axial type hair dryer fan blade, the overall structure is the same as image 3 The structure of the axial hair dryer blades shown is similar, but the blades adopt the same blade design as that of Embodiment 1, including long blades and short blades. Similarly, the number of blades can be increased to achieve an increase in the output of the same motor While maintaining the compression ratio of the hair dryer fan blades, the weight of the hair dryer fan blades will not be greatly increased.

[0039] In this embodiment, similar to Embodiment 1, the long blades and short blades are paired and connected to each other, which can increase the overall rigidity of the battery wind blade and reduce the noise during the operation of the hair dryer blade.

Abstract

The invention discloses a novel electric hair drier blade. The novel electric hair drier blade comprises a fixed base and blades distributed on the top surface of the fixed based in the circumferential direction, wherein the blades comprise a long blade and a short blade with the length being smaller than that of the long blade; the short blade is arranged at the outer edge of the top surface of the fixed base. The novel electric hair drier blade realizes the fact of effectively improving the air speed output of the electric hair drier blade, improves the overall rigidity of the blade on the premise of not greatly increasing the weight of the blade, reduces the vibration and jittering of the blade during high-speed running, and reduces the overall noise of an electric hair drier.

Description

technical field [0001] The invention relates to the technical field of hair dryer products, in particular to a novel hair dryer blade. Background technique [0002] At present, the existing hair dryers on the market can be divided into two types according to the air supply mode of the fan blades: centrifugal air supply hair dryers and axial air supply hair dryers. [0003] Centrifugal wind-supply hair dryers rely on the motor to drive the centrifugal blades to rotate, so that the air entering the hair dryer obtains inertial centrifugal force and continuously exhausts the air. The disadvantage of this type of hair dryer is that the exhausted wind does not all flow through the motor, and the motor tends to heat up higher, and the advantage is that the noise is lower. [0004] Axial air supply hair dryers rely on axial flow motors to drive axial fan blades to rotate, pushing the air entering the hair dryer to flow axially and continuously exhausting air. Its advantage is that...
