Breakdown index is as high as 20KV/mm.Micarex 4 rolls into shape corresponding with shell, is arranged on shell, is used for and shell
It is fixedly connected, for the fixed setting of ceramic block 1 on micarex 4, when heat generating device works long hours, temperature is higher, shell occurs
The case where body generates heat is reduced damage of the heat generating device to shell, is improved 5 shell of hair dryer due to the high-temperature insulation of micarex 4
The service life of body.
Wherein, heat generating device further includes anion module, and anion module is arranged on micarex 4, and negative ion device can
To be arranged among micarex 4, it also can be set in the top of micarex 4, be arranged with specific reference to actual needs.Hair dryer 5 exists
It can be heated in work, it is dry that the wind produced by boasting makes hair, and comb is also unavoidably used in use, and so hair just holds very much
It is easy to produce static electricity, and electrostatic can make hair modification, bending, or tilt, negative ion device can produce electronegative ionic particles (by
Anion generator generates) and vapor particle (being generated by semiconductor cooling device), the positive charge often having in hair is neutralized, from
And smooth and distribute arbituarily, keep its docile smooth, electrostatic can also be eliminated, allow the more smooth easy comb of healthy hair, modeling effect is more preferable.
Wherein, micarex 4 is equipped with fuse for protecting heating film, and fuse is mainly by melt and fusion tube and outer
Filled equal part forms.In use, the electric appliance of disjunction circuit using metallic conductor as melt, is series in circuit, has served as
When load or short circuit current pass through melt, melt itself will generate heat and fuse, thus to electric system, various electrical equipments and family
Electrical appliance all plays certain protective effect.With inverse time delay characteristics, when overload current is small, fusing time is long；Overload electricity
When flowing big, fusing time is short.Therefore, restore normal to electric current within the scope of certain overload current, fuse will not fuse, can be with
It continues to use.
A kind of hair dryer 5 installs the shape of heat generating device position according to hair dryer 5 including above mentioned heat generating device
Micarex 4 is rolled, the outside of the micarex 4 rolled is fixedly mounted on the case inside of hair dryer 5, and the shape of ceramic block 1 is
