WIPO Patent Application WO/2020/186855
Kind Code:

Abstract:
A hair drier, relating to the technical field of home appliances. The hair drier comprises an air blowing cylinder (100) and a handle (200). An air blower assembly (13) and an electronic control PCB board (14) sleeved on the air blower assembly (13) are provided in the air blowing cylinder (100). The electronic control PCB board (14) is electrically connected to the air blower assembly (13). The electronic control PCB board (14) is located outside a main air channel of the air blowing cylinder (100). The electronic control PCB board (14) is connected to a heat dissipation structure. In the hair drier, the air blower assembly (13) and the electronic control PCB board (14) are located in the air blowing cylinder (100), and the electronic control PCB board (14) is designed to be annular, and is sleeved on the air blower assembly (13), so that the air blower assembly (13) and the electronic control PCB board (14) are assembled in a compact manner, and the space occupied by the air blower assembly (13) and the electronic control PCB board (14) is reduced. The layout is rational and allows a reduction in the size of the air blowing cylinder (100), and the air blowing cylinder (100) has the same size as or can even be smaller than an air blowing cylinder (100) in a hair drier in the prior art in which a fan is disposed in a handle (200). For the same size air blowing cylinder (100), providing the air blower assembly (13) in the handle (200) and providing the air blower assembly (13) in the air blowing cylinder (100) reduces the length of the air channel, thereby improving the efficiency of the hair drier.
