The movable clip member 22 is pivotally connected to the movable clip pivot seat 212 of the main body housing member 21. Moreover, the main body housing member 21 and the movable clip member 22 can relatively open / close, so that the main body housing member 21 and the movable clip member 22 form a clamping structure. That is, the movable clip member 22 serves as one half of the clamping structure, and the main body housing member 21 serves as the other half of the clamping structure. It can be understood that a torsion spring (not shown in the figure) is provided between the movable clip member 22 and the main body housing member 21, and this torsion spring keeps the movable clip member 22 and the main body housing member 21 in a closed state when not stressed.

Moreover, the fan blade 152 is surrounded by the cylindrical outer contour structure of the motor 151; the motor 151 of the fan assembly 15 is accommodated and fixed in the air duct structure 10 of the air duct housing assembly, and specifically, the motor 151 can be fixed in the main air duct housing member 11 by means of a buckle or adhesive.

[0034] Specifically, a pivot seat 111 is provided on the side surface of the main air duct housing member 11 of the air duct housing assembly. The pivot seat 111 can be integrally formed on the main air duct housing member 11 or can be an independent component and is fixed to the main air duct housing member 11 by screws or buckles; one end of the main housing member 21 of the main body unit 2 is provided with a pivot shaft 211. In this embodiment, the pivot shaft 211 is a shaft-shaped member made of engineering plastic buckled on the main housing member 21; the pivot seat 111 of the main air duct housing member 11 cooperates with the pivot shaft 211 of the main housing member 21 of the main body unit 2, so that the air duct housing assembly of the air outlet unit 1 is pivotally connected to one end of the main housing member 21 of the main body unit 2. In this way, it is realized that the air outlet unit 1 can swing in the pitch angle relative to the main housing member 21.

[0035] It can be understood that by changing the direction of the pivot shaft 211 of the main housing member 21, it is possible to realize that the air outlet unit 1 can swing in the left and right angles relative to the main housing member 21; by setting the pivot shaft 211 of the main housing member 21 as a ball shaft and setting the pivot seat 111 of the main air duct housing member 11 as a ball socket, it is possible to simultaneously realize that the air outlet unit 1 can swing in the pitch angle and the pitch angle relative to the main housing member 21.

[0036] Furthermore, in the main body unit 2: on one side of the main housing member 21 relative to the movable clamping member 22, and / or on one side of the movable clamping member 22 relative to the main housing member 21, an elastic member 25 is provided; specifically, the elastic member 25 is one of rubber material, silicone material or foam material, and is fixed to the surface of the main housing member 21 and / or the movable clamping member 22 by adhesive; in this embodiment, elastic members 25 are provided at both the main housing member 21 and the movable clamping member 22.

[0037] Further, in the main body unit 2: A switch 241 is mounted on the circuit board 24. The switch 241 is a micro switch and is mounted on the circuit board 24 in a plug-in form; A key 213 is embedded in the main body shell member 21. The key 213 is a key made of engineering plastic; The key 213 at the main body shell member 21 is aligned with the switch 241 on the circuit board 24. When the key 213 is pressed, the switch 241 can be triggered, thereby realizing the on / off of the clip fan and the adjustment of the wind speed gear.

[0038] It can be understood that a charging interface (not shown in the figure), such as a Type-C interface or a Micro USB interface, is also mounted on the circuit board 24, and the charging interface extends from the main body shell member 21 to charge the battery 23.

[0039] When the clip fan of this embodiment is in use, the circuit board 24 is powered by the battery 23. Press the key 213 to trigger the switch 241 of the circuit board 24 to realize the startup and wind speed gear adjustment of the clip fan; The circuit board 24 supplies power to the motor 151 of the fan assembly 15. The motor 151 runs and drives the fan blade 152 to rotate. The air flow is sucked from the rear air inlet net member 13 into the main air duct shell member eleven, and then enters the air duct structure 10. After the air flow passes through the fan blade 152 and the motor 151 in sequence, it reaches the large end of the air collecting hood member 14. After being gathered by the air collecting hood member 14, it is blown out from the small end of the air collecting hood member 14 and finally blown out of the air duct structure 10 through the front air outlet cover member 12; Opening the main body shell member 21 and the movable clip member 22 can make the main body unit 2 clamp fixed objects such as the edge of a table, the wall of a cabinet, the back of a chair, and a railing, thereby fixing the entire clip fan; The elastic member 25 provides buffering and greater friction for the main body shell member 21 and the movable clip member 22.

[0040] In the clip fan of this embodiment, the fan assembly 15 is accommodated and fixed in the air duct structure 10 of the air duct shell assembly, so that the air flow driven by the fan assembly 15 is gathered in the air duct structure 10 and jets out along the central axis of the air duct structure 10, which is not easy to diverge, improving the degree of air flow aggregation and flow velocity, thereby providing a structurally reasonable air outlet unit 1 for the clip fan and improving the air outlet effect of the air outlet unit 1; The battery 23 and the circuit board 24 are both accommodated and fixed in the main body shell member 21. The main body shell member 21 provides a dedicated accommodation space with sufficient volume for the battery 23, so that the clip fan can be configured with a battery 23 with sufficient capacity, improving the battery life of the clip fan; The main body shell member 21 and the movable clip member 22 can be opened / closed relatively, so that the main body shell member 21 and the movable clip member 22 form a clamping structure. Using the main body shell member 21 as half of the clamping structure, the clamping structure is ingeniously simplified, the volume of the clamping structure is reduced, and then the overall volume of the clip fan is reduced, improving the portability of the clip fan.
