Problems solved by technology

[0005] The disadvantage of the leafless high-speed hair dryer technology solution currently on the market is that the circuit board is placed on the top and rear of the hair dryer, the air flow here is not very smooth, and the heat dissipation problem has always been a big problem
I haven't seen the actual product on the market, so I don't know how it works

Embodiment 2

[0042] Such as Figure 6 As shown, the difference from Embodiment 1 is that the composition surface of the internal guide structure 12 that surrounds the annular cavity 13 is a smooth arc surface, and the structure and size of the annular gap 14 are supported by setting the support member 9 to support The member 9 may include 3, 4, 6 or 8 supporting points 10, and the supporting points 10 are evenly arranged in the annular gap 14 around the circumference.

Embodiment 1

[0043] For Example 1, the experimental test was done with a hand-held hair dryer with support 9 including 3 support points 10, as follows:

[0044] Wind speed: remove the air nozzle, on the axis of the air outlet tube, at a distance of 0mm, 100mm, and 200mm from the air outlet, use an anemometer to test the highest wind speed;

[0045] Air volume: Remove the air nozzle, measure the wind force (that is, air volume) with an electronic scale on the axis of the air outlet, 10mm, 100mm, and 200mm away from the air outlet;

[0046] Electronic scale measurement range: 0 ~ 500 grams;

[0047] Measuring range of anemometer: 0.3m / s~45m / s;

[0048] Ambient temperature: 26.8°.

Abstract

A handheld electric hair dryer is disclosed in the invention, and comprises a hair dryer body and a handle, the hair dryer body comprises a body shell part and an internal flow guide structure, the body shell part and the internal flow guide structure form an internal annular cavity and a through air outlet channel surrounding the central axis of the hair dryer body, and a heating unit is arrangedin the annular cavity; the annular cavity is provided with an air outlet, the air outlet is an annular gap and is used for guiding circulating air in the annular cavity to the air outlet channel, thebody shell part comprises an air inlet opening part, the air inlet opening part is communicated with one end of the handle, the handle is of a hollow structure, the hollow structure is an air inlet channel, a fan unit and a single-chip microcomputer control unit are arranged in the hollow structure, and a filtering device is arranged at the end, away from the blower body, of the handle. Accordingto the invention, the loss of wind speed and wind pressure can be reduced, and a coanda effect is generated, so that the wind speed is higher and more stable and can reach 20m / s, and the hair can bedried more quickly.

Description

technical field [0001] The invention relates to the field of hair dryers, in particular to a hand-held high-speed motor and fan blades driven by electric heating hot air hair dryers, such as hair dryers and hair dryers in the field of small household appliances. Background technique [0002] Hair dryers are mainly used for drying and shaping hair, and can also be used for partial drying, heating and physical therapy in laboratories, physiotherapy rooms, industrial production, and art. [0003] Usually, a motor and fan blades are provided, which suck air into the body, and blow it out after being heated by a heating wire. Typically such hair dryer appliances are provided with a collecting or diffuser nozzle which can be attached to or detached from the hair dryer appliance and which changes the speed and direction of the air flow expelled from the hair dryer appliance. [0004] Dyson patent CN201621361236.9 discloses a handheld product using a high-speed motor. The rotation...
