Embodiment Construction
[0010] like figure 1 , 2 As shown, the electric heating hair dryer includes an insulating housing 1, a heating element 2 and an air supply device 3, and the housing 1 is made of a heat-insulating, insulating material such as plastic. The housing 1 is provided with a cavity and a handle for installing the heating component 2 and the air supply device 3. The openings at both ends of the cavity of the housing 1 constitute an air inlet 101 and an air outlet 102 respectively, and a power switch is provided on the handle. 4. like image 3 As shown, the heating element 2 includes a heating cylinder 201 and a helical coil 202 made of steel material. The heating cylinder 201 is a cylindrical structure with two ends open. The wind speed of the air outlet 102, the helical coil 202 is sleeved on the outer cylinder wall of the heating cylinder 201, or can be wound around a cylindrical frame, and the helical coil is made of enameled copper wire. An insulating layer is provided between t...

The invention relates to an electric heating hair drier. The electric heating hair drier comprises an insulating shell, a heating component and an air supply device, wherein the shell is provided with an air inlet, an air outlet and a handle part which a user can hold, and the heating component is arranged in an inner cavity of the shell. The electric heating hair drier is characterized in that the heating component comprises a heating barrel and a spiral coil, the heating barrel is made of steel and iron materials, the outer barrel wall of the heating barrel is sleeved with the spiral coil, an insulating layer is arranged between the spiral coil and the outer barrel wall and the heating barrel, and a power switch is arranged on the handle part. According to the electric heating hair drier, a high-frequency alternating power supply is arranged in the spiral coil, so that an induced eddy current is generated on the tube wall of the heating barrel to generate heat, air flowing in through the air inlet is rapidly heated by making direct contact with the tube wall of the heating barrel, and the efficiency is higher; meanwhile, due to the fact that the heating component of the electric heating hair drier is made of the steel and iron materials, the electric heating hair drier will not be damaged easily and is longer in service life.
Description
technical field [0001] The present invention relates to an electric heating hair dryer. Background technique [0002] The traditional electric hair dryer usually includes an insulating shell, a heating part and an air supply device. The heating part is composed of an insulating frame made of mica sheets and a heating wire erected on the insulating frame. The heating wire heats up, and the outside air is sucked in by the air supply device and blown through the heating wire, and the heated air is sent out from the outlet. The heating component of the traditional electric hair dryer, namely the heating wire, is mounted on an insulating frame made of mica sheets, which is very easy to damage and has a short service life, and the heating method using the heating wire is less efficient and wastes energy. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an electric heating hair dryer with high efficiency and longer service life in order to ove...
