This invention discloses a dual-motor hair dryer, relating to the field of hair dryer technology. It includes a housing, a handle, and a mounting cover installed inside the housing. It also includes a dual-system blowing assembly, a drive assembly, a first adjustment assembly, and a second adjustment assembly located inside the mounting cover. In use, the right-side main motor fan system, through the cooperation of the air guide tube, main air duct, and inner air duct, delivers gas to the inner cylinder, evenly passing through the heating element. Simultaneously, the left-side auxiliary motor fan system delivers gas to the outer air duct through the air guide tube, auxiliary air duct, and flow equalization pipe. The gas flows through the annular air cavity, forming an annular air curtain that surrounds the hot air along the central axis. The annular cold air curtain and the hot air along the central axis are coaxially superimposed. Furthermore, the main and auxiliary air ducts are isolated, ensuring that the high temperature of the main air duct does not affect the auxiliary motor, resulting in high operating efficiency for the auxiliary motor. The main motor also experiences stable load due to the smooth air duct, significantly improving the overall energy efficiency and further achieving energy savings.
