Description

Technical Field

[0001] The utility model relates to the field of hair dryers, in particular to a hair dryer with double air ducts. Background Art

[0002] A hair dryer is a common household appliance with a drying function. A hair dryer is used to style hair in a wet or dry environment. Generally speaking, a hair dryer includes two main components: a motor and a heating component. The operation mode is to suck the fluid into the hair dryer body through the motor, and the sucked fluid is heated by the heating component, so that the cold air becomes hot air and flows out from the hair dryer outlet to achieve the purpose of drying. Existing hair dryers can be roughly divided into two types according to the different air inlet positions: one is a rear air inlet hair dryer, in which the motor of this type of hair dryer is located at the rear end of the hair dryer body and sucks the fluid from the rear end, and the sucked fluid is heated by the heating component at the front end of the hair dryer body and then flows out of the body. Traditional hair dryers mostly use this air inlet method, but due to the influence of the motor and the heating component, the central flow velocity of the airflow in the hair dryer is slow and the temperature is high, which brings disadvantages such as poor consumer experience and affected life of the motor and the heating component. The second is a handle air inlet hair dryer, in which the fluid is sucked in from the bottom of the handle and passes through the handle, and the fluid path turns and enters the air outlet before flowing out. There is already a design in the prior art that sets the motor inside the handle, but the heating component is set at the air outlet unit. This design will make the temperature of the hot air and the cold air blown out by the hair dryer too high, affecting user use. Utility Model Content
