[0003] The present invention relates to hair driers, more
specifically, to a touch hair drier.
[0004] 2. Description of the Related Art
[0005] A hair drier is mainly used for hair treatment and
hair-drying, however, it is being widely employed in laboratory,
physiotherapy rooms, industrial production and in art design as
well for the application of partially drying, heating and
physiotherapy. Hair driers are substantially composed of three
major components: motors and blades thereof, heating elements and
electric-control switch elements, even with huge differences
between various hair driers in terms of sizes, types and
appearances. A micro hair drier is formed by the combination of
motors, blades and housing. Hair driers are directly driven by
motors of which rotors rotate blades. While the blades are
rotating, air is sucked in from the inlets, thus centrifugal air
flow is formed, then the air flow is transferred out by the front
mouths of the hair driers. During the air passing through the hair
drier, if the heating wires on the heating supports in the mouths
are heated, the wind turns to heated wind. Otherwise, it is cold
wind. Therefore, the purposes of hair drying and hair treatment are
achieved.
[0006] The general power switches of said hair driers are normally
arranged on the handle. And after the switches are pressed, blades
and heating elements turn to be power on and in operation. During
the use of the hair drier, if the user stop using the hair drier
and forgets to turn off the power and leave it for a long time, the
fire disaster caused by the combustible near the heat may
occur.
[0007] To solve the above safety issue, Chinese Patent (CN
203493012 U) disclosed a smart outage safe hair drier. As shown in

and a Second Switch 106 are arranged on the handle. A First
Microswitch 107 and a Second Microswitch 108 are arranged on the
two sides of Shell Body 101 respectively. The electric hair drier
obtains power and works only when the two relevant Microswitches
107 and 108 are not in contact with each other, only when the
electric hair drier is held by hands, the electric hair drier can
work.
[0008] Although the above hair drier solve the safety issue of the
exiting hair driers to some extent, if the drier is put in a lumpy
surface of an object and thus the microswitches are therefore not
touched with each other, the safety issue may still be
occurred.
