[0035] like Figure 1-Figure 3As shown, the embodiment provides a clip fan, which comprises a swing head assembly 1, a fixed shaft 2, an air outlet assembly 3 and a control assembly 4. The swing head assembly 1 comprises a swing head part 11, a driving part 12 and a photoelectric detection switch 13. The photoelectric detection switch 13 and the driving part 12 are arranged on the swing head part 11. The photoelectric detection switch 13 is provided with a detection groove 131. The fixed shaft 2 is provided with a baffle 211. The driving part 12 is used for driving the swing head part 11 to rotate relative to the fixed shaft 2. The air outlet assembly 3 is connected to the swing head part 11. The air outlet assembly 3 can swing to a first limit working position, an intermediate working position and a second limit working position along with the swing head assembly 1. The intermediate working position is located in the middle of the first limit working position and the second limit working position. When the air outlet assembly 3 swings to between the first limit working position and the intermediate working position along with the swing head assembly 1, the baffle 211 is located in the detection groove 131, and the photoelectric detection switch 13 outputs a first signal. When the air outlet assembly 3 swings to between the intermediate working position and the second limit working position along with the swing head assembly 1, the baffle 211 is located outside the detection groove 131, and the photoelectric detection switch 13 outputs a second signal. The control assembly 4 is electrically connected to the photoelectric detection switch 13 and the driving part 12.

[0036] During the working process of the clip fan, the control assembly 4 can acquire the signal of the photoelectric detection switch 13. When the photoelectric detection switch 13 outputs the first signal, the baffle 211 is located in the detection groove 131 at this time, and the air outlet assembly 3 swings to between the first limit working position and the intermediate working position along with the swing head part 11. When the photoelectric detection switch 13 outputs the second signal, the baffle 211 is located outside the detection groove 131 at this time, and the air outlet assembly 3 swings to between the intermediate working position and the second limit working position along with the swing head part 11. When the first signal and the second signal output by the photoelectric detection switch 13 are switched, the air outlet assembly 3 swings to the intermediate working position along with the swing head part 11 at this time. Through the output signal of the photoelectric detection switch 13, the control assembly 4 can accurately detect the current position of the air outlet assembly 3, and the control assembly 4 can also control the swing angle of the air outlet assembly 3 through the driving part 12.

[0037] In this embodiment, the control component 4 includes an MCU42 (Microcontroller Unit). The key points of the structural design of the baffle 211 are that when the air outlet component 3 swings between the first extreme position and the middle position, the baffle 211 is located in the detection slot 131. The baffle 211 blocks the transmitting and receiving channels of the photoelectric detection switch 13, blocking the signal. The MCU42 of the control component 4 records the first signal when blocked as a low level; when the air outlet component 3 swings between the middle position and the second extreme position, the baffle 211 is located outside the detection slot 131 and does not block the photoelectric detection switch 13. The MCU42 of the control component 4 records the second signal when not blocked as a high level. When the air outlet component 3 swings left and right, the detection signal of the photoelectric detection switch 13 allows the MCU42 to accurately capture the high and low changes of the signal, and the mutation point of the signal from high level to low level or from low level to high level will be recorded by the MCU42 as the center point of the air outlet component 3 shaking left and right.

[0038] Furthermore, the oscillating component 11 includes a connecting base 111 and a mounting base 112 that are interconnected. The driving component 12 is connected to the connecting base 111, and the air outlet assembly 3 is connected to the mounting base 112. The mounting base 112 is provided with a first through-hole 1121, through which the fixed shaft 2 is passed, and the mounting base 112 is rotatably connected to the fixed shaft 2. In this embodiment, the photoelectric detection switch 13 is connected to the connecting base 111, and a bearing 113 is provided between the first through-hole 1121 and the fixed shaft 2. The mounting base 112 is rotatably connected to the fixed shaft 2 via the bearing 113. The connecting base 111 and the mounting base 112 can be connected by screws. When the air outlet assembly 3 swings with the oscillating component 11, the fixed shaft 2 remains stationary.

[0039] Furthermore, the drive component 12 includes a drive member 121 and a drive gear 122. The connecting base 111 is provided with a connecting hole, and the drive member 121 is connected to the connecting hole. The drive member 121 is drivingly connected to the drive gear 122. The top end of the fixed shaft 2 is provided with a semi-annular portion 21. Part of the semi-annular portion 21 is a blocking plate 211, and the other part is provided with a toothed groove 212. The drive gear 122 is meshed and connected to the toothed groove 212. When the drive member 121 drives the drive gear 122 to rotate, the drive gear 122 meshes with the toothed groove 212 for transmission. Since the position of the toothed groove 212 does not change, the drive member 121 and the oscillating component 11 rotate, thereby enabling the drive member 12 to drive the oscillating component 11 to rotate relative to the fixed shaft 2. In this embodiment, the drive member 121 is a stepper motor.

[0040] In this embodiment, Figure 2-Figure 4As shown, the top end of the mounting base 112 is provided with a receiving groove 1122, the semi-ring-shaped part 21 is located in the receiving groove 1122, the groove bottom of the receiving groove 1122 is provided with a first stop protrusion 1123, the semi-ring-shaped part 21 is provided with two second stop protrusions 213 at the side close to the groove bottom of the receiving groove 1122, the first stop protrusion 1123 is located between the two second stop protrusions 213, and when the air outlet assembly 3 is swung to the first limit position or the second limit position, the first stop protrusion 1123 respectively abuts against the two second stop protrusions 213, so as to prevent the swing angle of the air outlet assembly 3 from being too large. It should be noted that in the swing structure design of the air outlet assembly 3, the two second stop protrusions 213 are used as the limit position structure of the left and right swing of the air outlet assembly 3, and the air outlet assembly 3 is limited to swing after being swung to the first limit position or the second limit position, at this time, the current of the stepping motor is increased, and when the air outlet assembly 3 is swung to the limit position structure, the control assembly 4 can detect the current change signal of the limited stepping motor, so as to determine that the air outlet assembly 3 reaches the first limit position or the second limit position.

[0041] In the embodiment, the air outlet assembly 3 comprises a cover 31, a fan blade 32 and a fan blade motor, the cover 31 covers the fan blade 32 and is connected to the mounting base 112, the fan blade motor is drivingly connected to the fan blade 32, and the fan blade motor is electrically connected to the control assembly 4. In the embodiment, the control assembly 4 comprises at least two buttons 41, and the at least two buttons 41 are used to make the MCU 42 control the rotation signal of the fan blade 32 in the air outlet assembly 3 and the swing angle signal of the air outlet assembly 3 when triggered. In the embodiment, the swing part 11 further comprises an outer cover 114, and the buttons 41 are arranged at the top end of the outer cover 114.

[0042] Further, as shown in FIG. 6, the air outlet assembly 3 is provided with a plurality of air outlet nozzles 33, and the air outlet nozzles 33 are arranged in the form of an array. Figure 1 and Figure 2As shown, the clip fan also includes a clamping assembly 5, which includes a knob 51, a connecting member 52, and a clamping member 53. One end of the connecting member 52 is connected to the fixed shaft 2, and the other end is hinged to the clamping member 53. The knob 51 is used to adjust the relative angle between the connecting member 52 and the clamping member 53. Specifically, the first end of the clamping member 53 is used to clamp a predetermined position, and the second end of the clamping member 53 is provided with a hinge groove. One end of the connecting member 52 is connected to the fixed shaft 2, and the other end is provided with a hinge protrusion, which is hinged within the hinge groove. One of the opposing side walls of the hinge groove is provided with a first through hole 1121, and the other is provided with a threaded hole. The hinge protrusion is provided with a second through hole. The knob 51 is inserted through the first through hole 1121 and the second through hole and is threadedly connected to the threaded hole. The knob 51 is used to adjust the distance between the opposing side walls of the hinge groove. The clip fan can be clamped to a predetermined position by the first end of the clamping member 53, facilitating the fixing of the clip fan. When it is necessary to adjust the pitch angle of the air outlet component 3, loosen the knob 51. At this time, the connecting component 52 can rotate relative to the clamping component 53 to achieve pitch adjustment. When the air outlet component 3 is adjusted to the preset pitch angle, tighten the knob 51. At this time, the distance between the opposite side walls of the hinge groove is reduced, and the opposite side walls of the hinge groove clamp the connecting component 52. At this time, the connecting component 52 is fixed relative to the clamping component 53 to keep the air outlet component 3 at the preset pitch angle.

[0043] In this embodiment, the connecting component 52 includes a connecting arm 521 and a connecting shell 522 . The fixed shaft 2 , the connecting arm 521 and the connecting shell 522 are connected in sequence, and a hinge protrusion is provided on the connecting shell 522 .

[0044] In this embodiment, a clamp 531 is provided at one end of the clamping component 53 away from the connecting component 52. Preferably, the clamp 531 is provided with a clamping hole 5312, and the clamping hole 5312 is square.
