The central air duct 107 and the main air duct 106 may or may not communicate with each other. The number of the main air ducts 106 is 3 in this example. It is understood that the number of primary air ducts 106 is two, four, five, etc.
Further, as shown in fig. 2, 3 and 4, the partition plates 105 have free ends 1051, and the free ends 1051 of two adjacent partition plates 105 define a central air passage 107 communicating with the main air passage 106. On the same cross section, a virtual separation line is formed by connecting two adjacent free ends 1051, a virtual separation surface 108 is formed by a plurality of virtual separation lines along the central line direction of the outer cylinder 101, and the central air duct 106 and the main air duct 107 are communicated at the virtual separation surface 109.

The central duct 107 has an inlet and an outlet, the area of the inlet being larger than the area of the outlet. The central air duct 107 is a space that penetrates from the first inlet to the outlet, and a part of the air flow received by the air nozzle 1 enters the central air duct from the first inlet and is blown out from the outlet. In this example, the cross-sectional area of the center duct 107 gradually decreases in the direction of the center line of the outer cylinder 101.
The main duct 106 has a second inlet and a second outlet, and the area of the second inlet is larger than that of the second outlet. The air inlet has the advantages that the area of the second inlet is larger, so that more air flow can enter the main air duct, and the air quantity in the main air duct is increased; the area of the second outlet is reduced, the sectional area of the main air duct is changed, the speed of air flow blown out from the main air duct is improved, the strength of the air flow blown out is improved, wet hair is scattered, the contact area of warm air and the wet hair is increased, and the drying efficiency is improved.

In this example, the partition plate 105 is formed by radially inwardly recessing the side wall of the outer cylinder 101, and the side wall of the outer cylinder 101 is formed with an inward recess 109, and the inward recess 109 partitions the partition plate 105 into a first partition plate and a second partition plate.
The slope of the partition plate 105 becomes smaller along the direction of the center line of the outer cylinder 101, and the structure enables the partition plate 105 to be in a streamline shape, so that the wind resistance is reduced, and the wind loss is reduced. The partition 105 includes a first side 1052 and a second side 1053, the first side 1052 or the second side 1053 includes a first surface 5 and a second surface 6 having different slopes, the slope of the first surface 5 is greater than that of the second surface 6, the first surface 5 is close to the air inlet 102, which has the advantage that the first surface 5 guides more air into the main air duct 106, and the second surface 6 changes the direction of the air flow, so that the air flow is blown out from the air outlet 103 according to a preset angle, thereby increasing the air flow of the air flow blown out from the main air duct 106, facilitating the wet hair spreading and drying the hair quickly. In this example, the first side 1052 and the second side 1053 each have a first face 5 and a second face 6. It will be appreciated that the sides of the divider plate 105 may be comprised of a plurality of surfaces having different slopes, with the slope of the surface adjacent the air inlet 102 being the greatest and the slope of the surface adjacent the air outlet 103 being the least.
In this example, the first side 1052 and the second side 1053 are the surfaces of the first partition plate and the second partition plate near the main air duct 106.
