[0037] To make the technical content, the purposes and effects of the present application clear, the following will be described in combination with the embodiments and the drawings.

[0038] Please refer to Figs. 1-3 A fan, comprising a swing head 1 and a swing device 2; the swing head 1 is connected with the swing device 2. The swing device 2 comprises a chassis assembly 21, a rotating assembly 22, a driving assembly 23 and a twistable power supply assembly 24; the driving assembly 23 is arranged in the rotating assembly 22, and the rotating assembly 22 and the chassis assembly 21 are relatively rotatably connected through the driving assembly 23; one end of the power supply assembly 24 is arranged in the chassis assembly 21, and the other end of the power supply assembly 24 is inserted into the rotating assembly 22 and is electrically connected with the driving assembly 23.

[0039] It can be understood that, by arranging the driving assembly 23 and the twistable power supply assembly 24, the rotating assembly 22 and the chassis assembly 21 can be reciprocally swung 360° under the driving of the driving assembly 23, the range of the swing head 1 of the fan is expanded, and the blowing range is expanded. Since the twistable power supply assembly 24 is arranged, the power supply assembly 24 does not interfere with the rotation of the rotating assembly 22, and the fluency of the rotation of the rotating assembly 22 is ensured.

[0040] In some embodiments, the driving assembly 23 has a fixed end 231 and a movable end 232; the fixed end 231 of the driving assembly 23 is connected with the chassis assembly 21, and the movable end 232 of the driving assembly 23 is drivingly connected with the rotating assembly 22, for driving the rotating assembly 22 to rotate relative to the chassis assembly 21.

[0041] In some embodiments, the driving assembly 23 comprises a driving member 233, a driving gear 235 and a driven gear 236; one end of the driving member 233 is in driving connection with the driven gear 236, the driven gear 236 is in meshing connection with the driving gear 235; the driving gear 235 is connected with the chassis assembly 21. Preferably, the driving member 233 is a stepping motor. By arranging the driving gear 235 on the chassis assembly 21 and arranging the driven gear 236 and the driving member 233 in the rotating assembly 22, the driving member 233 drives the driven gear 236 to rotate relative to the driving gear 235, so as to drive the rotating assembly 22 to rotate relative to the chassis assembly 21, and further drive the swing head 1 to swing in the range of 0°-360°, thereby expanding the air outlet range.

[0042] In some embodiments, the driving assembly 23 further comprises a control circuit board; the control circuit board is arranged in the rotating assembly 22, and the power supply assembly 24 is in electrical connection with the control circuit board. Preferably, the control circuit board is a PCB board. The power supply assembly 24 is in electrical connection with the control circuit board, and the control circuit board is in electrical connection with the driving member 233, which is used to supply power to the driving member 233 and control the operating state of the driving member 233, so as to control the position and swing state of the swing head 1.

[0043] In some embodiments, the power supply assembly 24 comprises a fixed power line 241 and a spring wire 242; the fixed power line 241 is embedded in the chassis assembly 21, and the spring wire 242 is in electrical connection with the output end of the fixed power line 241; the spring wire 242 passes through the driving gear 235 of the driving assembly 23 in sequence and is in electrical connection with the control circuit board. Since the spring wire 242 has the characteristic of being twistable, one end of the spring wire 242 is in electrical connection with the control circuit board, which avoids interference with the rotation of the driving assembly 23 and the rotating assembly 22 and expands the rotation range; and the fixed power line 241 is fixed in the chassis assembly 21, which can ensure the stability of the input end of the power supply assembly 24 and the service life of the power supply assembly 24. Alternatively, in other equivalent embodiments, the spring wire 242 can be replaced by a rotary joint. Further, a wire pressing plate 243 is arranged at the end of the fixed power line 241 close to the spring wire 242, which is used to press the fixed power line 241 to prevent the fixed power line 242 from being warped and rubbing against the driving gear 235, thereby preventing noise.

[0044] In some embodiments, the rotating assembly 22 comprises a bottom cover 221 and a top cover 222; the swing head 1 is connected with the top cover 222, the top cover 222 is arranged on the bottom cover 221, and the driving assembly 23 is located in the accommodation cavity formed between the top cover 222 and the bottom cover 221.

[0045] In some embodiments, the chassis assembly 21 includes a chassis body 211 and a gasket 212. The gasket 212 is embedded in the chassis body 211 and presses against the rotating assembly 22. Specifically, a receiving groove 2211 is defined on the side of the rotating assembly 22 facing the chassis assembly 21, allowing the gasket 212 to be embedded in both the chassis body 211 and the bottom of the rotating assembly 22. Due to the provision of the gasket 212, a rotational clearance exists between the chassis assembly 21 and the rotating assembly 22 in the axial direction of the chassis assembly 21. To reduce the frictional resistance encountered by the rotating assembly 22 and the chassis assembly 21 during rotation, grease or lubricating oil may be applied to the groove of the chassis body 211 and the receiving groove 2211 of the rotating assembly 22 to fully lubricate the gasket. This allows the gasket to provide shock absorption and cushioning between the rotating assembly 22 and the chassis assembly 21, support the rotating assembly 22, and improve sealing.

[0046] In some embodiments, the rotating assembly 22 and the chassis assembly 21 are interlocked in the radial direction of the chassis assembly 21. Accordingly, a rotation groove 2212 is defined on the side of the rotating assembly 22 facing the chassis assembly 21, and the chassis assembly 21 is embedded in the rotation groove 2212, so that the chassis assembly 21 and the rotating assembly 22 are interlocked in the radial direction. This means that the rotating assembly 22 and the chassis assembly 21 are mutually restrained in the radial direction of the chassis assembly 21, maintaining a relatively stable positional relationship between the two.

[0053] In the embodiment, the chassis assembly 21 comprises a chassis body 211 and a gasket 212; the gasket 212 is embedded on the chassis body 211, and the gasket 212 is abutted against the rotating assembly 22, so that the rotating assembly 22 and the chassis assembly 21 have a rotating gap. Specifically, a receiving groove 2211 is formed on the side of the rotating assembly 22 facing the chassis assembly 21, so that the gasket 212 is embedded on the chassis body 211 and the bottom of the rotating assembly 22. The fixed gear 235 is locked on the chassis body 211 by a plurality of screws.
