Embodiment Construction
[0019] Now describe the hair dryer of an embodiment of the present invention according to the accompanying drawings. Fig. 1 shows the structure of the hair dryer according to this embodiment, which includes: a casing 2 with a cylindrical wind tunnel, a fan 4 and a motor 3 for driving the fan 4, and a core 1 for generating heat. The core 1 is supported inside the air outlet baffle 10, the switch 9 is located on the handle 8, the motor 3 is started through the switch 9 to make the fan 4 rotate to generate air flow, and the heat generated by the core 1 passes through the wind tunnel of the shell 2 from the outlet. The tuyere baffle 10 flows to the outside.
[0020] In more detail, Fig. 2, Fig. 3, Fig. 4, Fig. 5, and Fig. 6 directly or indirectly show the structure of the movement 1, which includes a bracket 5 and a heating element spirally wound on the bracket 5 11 (referring to Fig. 2, 4), support 5 is fixed by the gear rib in the wind tunnel of shell 2 to prevent whole movemen...

The invention discloses an electric hot wind device, and in particular relates to an electric hair drier. The prior cassette mechanism structure is not suitable for manufacturing an electric hair drier with small volume and large power. A heating body of the electric hair drier is in a spiral spring shape of which the cross section is in an elliptical shape made by winding electrically heated wires. The heating body is wound on the outer edge of a supporting frame, and the long axis direction of the cross section of the heating body is pointed to the interior of the wound cassette mechanism. Because the heating body is in the spiral spring shape of which the cross section is in the elliptical shape made by winding the electrically heated wires, the power of the electric hair drier can be adjusted by changing the proportion of the elliptical long axis and the short axis of the cross section of the heating body in the spiral spring shape, and is not limited by the wind hole space. Alongwith the increase of the power and the lengthening of the elliptical long axis of the cross section of the heating body in the spiral spring shape, the heat radiation of the cassette mechanism is more uniform, the hour temperature deviation of the wind hole is smaller so as to ensure that the temperature distribution of the wind hole of the electric hair drier is more uniform, thereby reducing the deformation state of the electrically heated wires caused by non-uniform heat, and prolonging the service life of the electric hair drier.
Description
technical field [0001] The invention relates to an electric heating air device, in particular to an electric hair dryer which improves the core structure to adapt to high power and uniformly dissipates heat from the core. Background technique [0002] At present, a typical hair dryer includes a cylindrical shell, a fan, a motor that drives the fan to rotate, and a core for heating; there are two types of cores in the prior art: [0003] The first is to make the linear heating wire into a broken line string. Its advantage is that the core has a wide wind-receiving area in the air duct and good heat dissipation; its disadvantage is that the length of the heating wire is largely limited due to the use of broken-line heating wires. At the same time, the discount cost is high and the yield rate is low. Suitable for low-power hair dryers. [0004] The second is to process the heating wire into a circular straight spring shape, which is wound around the outer edge of the support....
