[0033] See Figure 1 - Figure 2 , the present utility model provides a hair dryer with a swinging air structure, including a hair dryer body 1 and a rotating nozzle. A first air outlet 11 is provided on the hair dryer body 1. The rotating nozzle includes a nozzle body 2 and a nozzle seat 3 with openings at both ends. One end of the nozzle seat 3 is inserted into the hair dryer body 1, and the nozzle body 2 is rotatably connected to the other end of the nozzle seat 3. A second air outlet 21 is provided on the nozzle body 2, and the second air outlet 21 is in communication with the first air outlet 11. A rotation driving structure is provided on the rotating nozzle, and the air outlet part of the first air outlet 11 blows towards the rotation driving structure to drive the nozzle body 2 to rotate relative to the nozzle seat 3.

[0034] Specifically, a fan assembly is provided on the hair dryer body 1. The air outlet end of the fan assembly is in communication with the first air outlet 11. The airflow generated by the operation of the fan assembly blows towards the rotating nozzle through the first air outlet 11. Part of the air blows out from the second air outlet 21 towards the target object, and part blows towards the rotation driving structure. The rotation driving structure is driven by the airflow to drive the nozzle body 2 to rotate, so that the blowing range of the second air outlet 21 is wider, the blowing is more uniform, and the blowing efficiency is improved.

[0035] Furthermore, the second air outlet 21 is inclined outward. During the rotation of the second air outlet 21, a larger area range can be radiated, and the blowing efficiency is improved.

[0036] Further, a first bracket is provided on the inner wall of the nozzle seat 3, and a rotating shaft 31 is provided on the first bracket. A second bracket is provided on the inner wall of the nozzle body 2, and a shaft hole is provided on the second bracket. The rotating shaft 31 is rotatably inserted into the shaft hole, and the nozzle body 2 is inserted into an opening of the nozzle seat 3. It should be noted that both the first bracket and the second bracket are hollow structures that can allow air to pass through. The nozzle body 2 is a hollow structure. Through the cooperation and insertion of the rotating shaft 31 and the shaft hole, the nozzle body 2 can rotate relative to the nozzle seat 3.

[0037] Embodiment 1:

[0038] See Figure 3 and Figure 4 , the second air outlets 21 are two and are distributed vertically on the front side wall of the nozzle body 2. The rotation driving structure includes a first diversion block 22 and a second diversion block 23. Part of the right side of one second air outlet 21 is cut off to form the first diversion block 22, and part of the left side of the other second air outlet 21 is cut off to form the second diversion block 23. The inner wall and the outer wall of the first diversion block 22 are parallel and are both inclined wall surfaces. The inner wall and the outer wall of the second diversion block 23 are parallel and are both inclined wall surfaces. The air from the first air outlet 11 blows into the interior of the nozzle body 2, and part of it hits the inner walls of the first diversion block 22 and the second diversion block 23, so that a tangential component force is formed on the nozzle body 2 to drive the nozzle body 2 to rotate relative to the nozzle seat 3.

[0039] Further, the first diversion block 22 and the second diversion block 23 are symmetrically arranged about the center, which is beneficial to the nozzle body 2 maintaining balanced rotation.

[0040] Further, the nozzle seat 3 includes a nozzle seat main body 32 and a housing 33 provided on the outer peripheral wall of the nozzle seat main body 32. An elastic block is provided on the side wall of the nozzle seat main body 32, and an abutting block is provided on the inner wall of the housing 33. The inner wall of the elastic block abuts against the outer side wall of the nozzle body 2, and the abutting block is used to squeeze the elastic block so that the elastic block deforms towards the nozzle body 2 to adjust the rotation speed of the nozzle body. Specifically, when it is necessary to reduce the rotation speed of the nozzle body 2, rotate the housing 33 so that the abutting block abuts against the elastic block, and the elastic block undergoes elastic deformation to squeeze the outer side wall of the nozzle body 2, so that the rotational friction force between the nozzle body 2 and the nozzle seat main body 32 becomes larger, making it more difficult for the nozzle body 2 to rotate, thereby reducing the rotation speed of the nozzle body 2; when it is necessary to increase the rotation speed of the nozzle body 2, rotate the housing 33 so that the abutting block disengages from the elastic block, and the elastic block undergoes elastic reset after losing the external force, so that the rotational friction force between the nozzle body 2 and the nozzle seat main body 32 becomes smaller, making it easier for the nozzle body 2 to rotate, thereby increasing the rotation speed of the nozzle body 2.

[0041] Example Two:

[0042] Refer to Figure 5 - Figure 8 , the nozzle seat 3 includes a nozzle seat body 32 and a housing 33 provided on the outer peripheral wall of the nozzle seat body 32. The rotation driving structure includes a plurality of first air outlets 321 provided on the front end wall of the nozzle seat body 32 and a plurality of flow guide grooves 24 provided on the nozzle body 2. The nozzle body 2 is connected to the nozzle seat body 32. The first air outlets 321 are respectively communicated with the first air outlet 11 and the flow guide grooves 24. The flow guide grooves 24 are used to guide the air to form a tangential air flow component. Part of the air coming out of the first air outlet 11 is blown out obliquely upward after passing through the first air outlets 321 and the flow guide grooves 24, forming a tangential air flow component, which drives the nozzle body 2 to rotate relative to the nozzle seat 3.

[0043] Further, a plurality of inclined arc-shaped protrusions 25 are provided on the outer peripheral wall of the nozzle body 2. The plurality of arc-shaped protrusions 25 are evenly distributed in a ring shape. Each two arc-shaped protrusions 25 are spaced apart to form the flow guide groove 24. The flow guide groove 24 is used to guide the air to form an obliquely upward air flow force.

[0044] Further, a plurality of stoppers 331 are provided on the inner wall of the housing 33. One end of the stopper 331 abuts against the front end wall of the nozzle seat body 32, and the other end of the stopper 331 is connected to the rear end wall of the nozzle body 2. The stopper 331 is used to block the first air outlets 321 to adjust the rotation speed of the nozzle body 2.

[0045] Example Three:

[0046] Refer to Figure 9 - Figure 11 , the rotation driving structure is a second air outlet 26 provided on the side wall of the nozzle body 2. The second air outlet 26 is communicated with the first air outlet 11. Part of the air coming out of the first air outlet 11 is blown out from the second air outlet 26, forming a tangential air flow force, which drives the nozzle body 2 to rotate relative to the nozzle seat 3.

[0047] Further, the side wall of the nozzle body 2 extends outward to form the second air outlet 26, and a cover plate 27 is rotatably connected to the second air outlet 26, and a vent 271 is provided on the cover plate 27, and the cover plate 27 is used to rotate and block the second air outlet 26 to adjust the rotation speed of the nozzle body 2. Specifically, the second air outlet 26 is a semicircular air outlet, and the vent 271 is also a semicircular air outlet. When the vent 271 completely overlaps with the second air outlet 26, the air volume of the second air outlet 26 reaches a maximum value, and the nozzle body 2 reaches a maximum rotation speed. When the vent 271 is completely staggered with the second air outlet 26, the sealing portion on the cover plate 27 completely blocks the second air outlet 26, and the second air outlet 26 cannot discharge air, and the nozzle body 2 cannot rotate.

[0048] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model.
