Title:
HAIR DRIER WITH HIGH HEAT DISSIPATION EFFICIENCY
Document Type and Number:
WIPO Patent Application WO/2020/186854
Kind Code:
A1
Abstract:
Disclosed is a hair drier with a high heat dissipation efficiency. The hair drier comprises a machine body (1), and a heating device (2) arranged in the machine body (1), wherein the machine body (1) is internally provided with an air channel (11). The hair drier further comprises a heat dissipation device (3) made of a heat-conducting material, wherein the heating device (2) is located outside the air channel (11), and the heat dissipation device (3) is in heat-conducting connection with the heating device (2) and is at least partially arranged in the air channel (11). The hair drier with a high heat dissipation efficiency can utilize cold wind, such as natural wind, with a temperature lower than that of the heat dissipation device (3) to take away heat from the heat dissipation device (3), thereby achieving the effect of dissipating heat of the heating device (2), such that the problem that a main control board of an existing hair drier cannot dissipate heat well is solved.
