In the present application, the main body of the casing 100 is mainly block-shaped, and the corners are chamfered; in fact, the two ends of the casing 100 are arc-shaped, so that the whole casing 100 is more beautiful, small and smooth. Wherein the hollow hole 110 is mainly formed at one end of the casing 100, which facilitates the structural arrangement of the air duct assembly 200. According to bernoulli's principle, the flow velocity of the air outlet 120 is larger than the air flow velocity in the area directly opposite to the hollow hole 110, so that the air pressure around the air outlet 120 is lower than the air pressure in the area directly opposite to the hollow hole 110, and then the end face of the hollow hole 110 corresponding to one end of the whole air outlet 120 forms a negative pressure area, and further the air in the hollow hole 110 can be sucked, so that the part of air is accelerated by the air flow ejected by the air outlet 120, and further the air output of the whole hair dryer is improved. It should be noted that, the air in the side of the hollow hole 110 far from the air outlet 120 is substantially static, but after the air is sucked by the negative pressure generated at the side of the air outlet 120, the air is driven to form an air flow, but the flow rate of the air flow is difficult to match the high-speed air flow coming out of the air outlet 120, which inevitably results in unstable air flow blown out by the whole hair dryer, overall air flow disturbance, and reduction of the use experience of the hair dryer.
