The present invention proposes a hairdryer 100.

Referring to fig. 1 to 3, and fig. 6, in an embodiment of the present invention, the hairdryer 100 includes a housing 10, a fan and a casing 20, an air duct is formed in the housing 10, and the housing 10 has an air inlet 1231 and an air outlet 112 which are communicated with the air duct; the fan is arranged in the shell 10 and positioned in the air duct; the outer shell 20 is sleeved and fixed on the outer side of the shell 10, and a silencing gap 10A is formed between the outer surface of the shell 10 and the inner surface of the outer shell 20.

Wherein, the fan may specifically be a motor driving a blade to perform rotary suction, and in order to improve the safety of using the hair dryer 100, the casing 10 may be made of plastic materials, for example: ABS, POM, PS, PMMA, PC, PET, other insulating materials may be used. Thus, when the hair dryer 100 leaks electricity, a user holds the handle 12 so as not to easily get an electric shock, and the safety of using the hair dryer 100 by the user is improved. Meanwhile, the housing 20 may be made of elastic material such as rubber, so that a user can obtain a better hand feeling when holding the hair dryer 100 for use. It should be noted that, when the noise reduction gap 10A is larger, the noise reduction effect is better, but the volume of the hair dryer 100 is correspondingly increased, so the present application only needs to ensure that the noise reduction gap 10A exists between the housing 10 and the shell 20, and the size of the noise reduction gap 10A can be selected according to those skilled in the art, which is not limited herein. In addition, the hair dryer 100 further includes a power cord 60, and the power cord 60 is connected to the housing 10 and extends out of the housing 10, so that it can be connected to an external power source to increase the endurance time.

The hair dryer 100 according to the present invention includes a housing 10, a fan and a casing 20, wherein an air duct is formed in the housing 10, and an air inlet 1231 and an air outlet 112 are provided in the housing 10, which are communicated with the air duct, the fan is disposed in the housing 10 and is located in the air duct, the casing 20 is sleeved and fixed on the outer side of the housing 10, and a silencing gap 10A is formed between the outer surface of the housing 10 and the inner surface of the casing 20. So when fan during operation produced sound can pass through casing 10 in proper order, amortization clearance 10A, shell 20 just passes in the external environment at last, can diffuse in the air when this in-process produced sound can pass through amortization clearance 10A, therefore the loudness of the produced sound of fan during operation weakens behind amortization clearance 10A, and then transmits the loudness of external environment less, so can reduce the noise of dry hair ware 100 during operation effectively, the degree that is influenced by fan noise when reducing the user and using dry hair ware 100, and then improve the comfort level that the user used dry hair ware 100.
