Technical Field

[0001] The utility model relates to the technical field of hair dryer structures, in particular to a hair dryer with a noise reduction structure. Background Art

[0002] A hair dryer consists of a heating wire and a small, high-speed fan. When powered, the heating wire generates heat, and the air blown by the fan passes through the heating wire and becomes hot air. If only the fan rotates without the heating wire heating up, the air blown out is just air, not heat.

[0003] Due to the characteristics of hair dryers that can quickly style and dry clothes, they have a large audience. The fan unit in the hair dryer can draw air from the air inlet of the hair dryer and send the drawn air out from the air outlet opposite to the air inlet, thereby achieving the purpose of drying. However, the hair dryer generates a lot of noise when it is running, and long-term use affects people's hearing health.

[0004] Therefore, how to achieve low-noise operation of the hair dryer is a technical problem that needs to be solved urgently in the industry. Utility Model Content

[0009] Preferably, a heating component is fixedly connected to the front end of the main body tube.

[0010] Preferably, the front portion of the outer surface of the main tube is fixedly connected to an outer frame body that matches its outer contour, a cavity is formed between the outer frame body and the outer surface of the main tube, and the interior of the cavity is filled with sound insulation cotton.

[0011] Preferably, a gripping handle is vertically fixedly connected to the bottom end of the rear portion of the outer surface of the main body tube, and the outer surface of the gripping handle is covered with an anti-slip cover.
