Their structures and the conditions required to be met are the same as those in Example 2 (such as Figure 4 ) to achieve the swingability of the inner air nozzle.

[0058] As a preferred embodiment, not only the inner air nozzle can be swung, but also the inner air nozzle has two states: a locked state and a swung state, and the user can choose according to the needs. Figures 18-19 They respectively represent the swingable state and the locked state of the nozzle of this embodiment. A first locking portion 13 is provided below the inner nozzle fixing portion 12, and a second locking portion 21 is provided on the outer nozzle seat body 2 and below the first locking portion 13. In this embodiment, the first locking portion 13 and the second locking portion 21 are only provided on one side of the front and rear sides of the hair dryer nozzle. In other embodiments, they can also be provided on both sides. When the inner nozzle housing 11 is pushed, the reset button 123 is fixed to the lower fixing hole 322, the second locking portion 21 is inserted into the first locking portion 13, and the inner nozzle 1 is locked relative to the outer nozzle; when the inner nozzle housing 11 is pulled, the reset button 123 is fixed to the upper fixing hole 321, the second locking portion 21 is away from the first locking portion 13, and the inner nozzle 1 can swing relative to the outer nozzle.
