Technical Field
The utility model relates to a device and hairdryer generate heat.
Background
At present, a typical hair dryer comprises a shell similar to a cylinder, a fan, a motor driving the fan to rotate and a movement for heating; the movement has two types in the prior art:
the first is to make the linear heating wire into a broken string. The air duct has the advantages that the air receiving area of the machine core in the air duct is wide, and the heat dissipation state is good; the electric hair drier has the advantages that the broken-line electric heating wires are adopted, so that the length of the electric heating wires is limited to a great extent, meanwhile, the folding cost is high, the yield is low, and the electric hair drier can only be suitable for low-power electric hair driers.
The second one is to process the heating wire into a round straight spring shape and wind the heating wire around the outer edge of the bracket. The structure has the advantages that the length of the electric heating wire can be increased and the power of the electric hair drier can be effectively increased because the electric heating wire is processed into the shape of the round straight spring. The structure has the disadvantages that along with the increase of power, the structure is limited by the space of the wind tunnel, the diameter of the spring made of the electric heating wire is limited, the length of the electric heating wire is limited, and the design of high power on the small-volume electric hair drier is difficult to realize; moreover, the electric heating wire is wound on the outer edge of the bracket, which is not beneficial to heat dissipation.
The hairdryer can not be used due to the fact that the movement is burnt out frequently in the using process, the service life of the heating device is short, after the hairdryer is damaged, if the hairdryer is maintained, the cost performance is not high, most users purchase the hairdryer again, and the hairdryer cannot be maintained.
