Heating is generally performed by using a heating wire, and the heating wire is mainly prepared from iron-chromium-aluminum alloy and nickel-chromium alloy series materials. However, the heating wire has low thermal efficiency, generally 15% of thermal efficiency output and high energy consumption; the heating wire is easy to redly and easily cause inflammable substances to burn, and the risk is high; the heating wire is easy to generate heat radiation, which is not beneficial to the health of users; the heating wire has slow heating rate and heat dissipation rate, and needs long waiting time to reach the use temperature or to be cooled to the room temperature; the high thermal conductivity of the heating wire enables the peripheral non-heating parts to generate high temperature, so that the temperature of the holding part of the appliance is too high, and the use experience of a user is affected.

In the embodiment, the electric heating coating 7 is a superconducting alloy coating, the heat efficiency of the superconducting alloy is high, the heat efficiency output is 95%, the energy consumption is low, and the use effect can be achieved under the condition of smaller power; the heating is not easy to reddening and does not generate heat radiation, the safety performance is high, the danger of inflammable substances can be effectively prevented, surrounding oxygen can not be burnt, the generation of hot or dry taste is avoided, and the dry and comfortable surrounding environment is kept; the heating rate is high, the use temperature can be reached within 1 second after the power is on, the heat is instantaneously generated, and accurate and high-efficiency heat energy can be generated; the heat dissipation rate is high, and the room temperature can be restored after 2-3 seconds of power failure; the heat conductivity is low, and heat is not easy to diffuse to peripheral components, so that the probability of scalding the holding part 2 is effectively reduced, and the use experience of a user is improved; the superconducting alloy has high self-melting point, can resist 1200 ℃ high temperature and has longer service life.

The thickness of the electrically heated coating 7 ranges from 1 to 200 μm. The airflow generating assembly 4 operates to generate an airflow using the extremely thin electrically heated coating 7 as a heat source, with about 90% of the heat of the electrically heated coating 7 being used to heat the airflow. The specific thickness of the electrically heated coating 7 may be set according to actual needs, and is not particularly limited herein. When the thickness of the electric heating coating 7 is less than 1 μm, the thickness thereof is too thin, the service life thereof is short, and when the thickness of the electric heating coating 7 is more than 200 μm, the heat dissipation efficiency thereof is slowed down, which is unfavorable for the high-efficiency heat dissipation thereof.

In one embodiment, the electrically heated coating 7 is formed on at least a portion of the inner wall of the duct housing 15 between the airflow generating assembly 4 and the air outlet 14, thereby preventing the heated airflow from causing heat loss during the flow-through process to reduce the hair drying efficiency.

The wires may be high temperature resistant wires to increase their useful life and enable low maintenance of blower 100. It is obvious that the wires are provided in two, which can be glued to the electrically heated coating 7 with conductive silver paste and connected to the switch 6 and the power supply.

The switch 6 is electrically connected with the electric heating coating 7, the switch 6 controls whether the electric heating coating 7 is powered or not so as to realize whether the electric heating coating 7 heats the air flow, and a user can selectively use cold air or hot air to blow.

The thickness-to-width ratio of the heating element is 1:40-2500. The thickness-to-width ratio of the heating element is too small, so that the heating element is too thin, the difficulty of a preparation process is increased, the heating element is easy to break, and the service life is limited. When the thickness-to-width ratio of the heating element is too large, the surface size of the heating element is smaller, the power consumption is large, and the air flow is heated to the same temperature, so that more energy is consumed. Therefore, the heating element is simple in preparation process, not easy to break, long in service life and low in power consumption.

In a preferred embodiment, the thickness of the heating element is 0.02-0.05mm, and the width is 2-5mm, so that the heating element has better heating effect, no self-damage and uniform heating.
