It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0049] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0051] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0052] like Figure 1-Figure 5 As shown, this embodiment provides a fan shaking angle adjustment method, which is applied to a fan, wherein the fan includes an air outlet component 3, and the air outlet component 3 can swing to a first extreme position, an intermediate position, and a second extreme position, wherein the intermediate position is located between the first extreme position and the second extreme position; the fan shaking angle adjustment method includes the following steps:

[0053] S1, controlling the air outlet component 3 to swing between the first extreme position and the second extreme position, and obtaining the signal sent by the fan in real time;

[0054] S21, when the first signal from the fan is obtained, it is determined that the air outlet assembly 3 swings to between the first limit position and the middle position;

[0055] S22, when the fan sends a second signal, it is determined that the air outlet assembly 3 swings to between the middle position and the second limit position;

[0056] S23, when the first signal and the second signal sent by the fan are switched, it is determined that the air outlet component 3 swings to the middle position.

[0057] When the fan is working, the air outlet component 3 is controlled to swing between the first extreme position and the second extreme position; when the first signal is obtained, it is determined that the air outlet component 3 swings between the first extreme position and the middle position; when the second signal is obtained, it is determined that the air outlet component 3 swings between the middle position and the second extreme position; when the first signal and the second signal are switched, it is determined that the air outlet component 3 swings to the middle position. The present invention solves the problem that the existing fan cannot accurately detect the center point of the fan's head swing and cannot determine whether the fan swings to the left or right side of the center point. By obtaining the information of the first signal and the second signal, the current swing position of the air outlet component 3 is accurately detected, reducing the difficulty of controlling the subsequent swing angle of the air outlet component 3.

[0058] Furthermore, the fan swing angle adjustment method further includes:

[0059] S31, controlling the air outlet assembly 3 to swing from the middle position to the first limit position;

[0060] S32, obtaining the time T1 of the air outlet component 3 swinging from the middle position to the first limit position;

[0061] S33, setting the shaking angle of the air outlet component 3 to M gears;

[0062] S34, when the Nth gear is controlled to work, the time for the air outlet component 3 to swing from the middle position to the left and right is N*T1 / M. In this embodiment, according to the gear number of the shaking head, the time from the middle position to the first extreme position and the second extreme position on the left and right is symmetrically divided to achieve precise control of the swing angle of the air outlet component 3 at different gears, and to achieve the left and right equidistant swing of the air outlet component 3 based on the middle position.

[0063] For example: when the shaking angle of the air outlet component 3 is set to 3 gears, when the first gear is controlled to work, the time for the air outlet component 3 to swing left and right from the middle position is 1*T1 / 3; when the second gear is controlled to work, the time for the air outlet component 3 to swing left and right from the middle position is 2*T1 / 3; when the third gear is controlled to work, the time for the air outlet component 3 to swing left and right from the middle position is 3*T1 / 3.

[0064] Preferably, the fan shaking angle adjustment method further includes:

[0065] S41, setting limit limit structures at both ends of the swing stroke of the air outlet component 3;

[0066] S42, using a stepping motor to drive the air outlet assembly 3 to swing;

[0067] S43, obtaining the current change value of the stepper motor, and when the current of the stepper motor increases, determining whether the air outlet component 3 swings to the first limit position or the second limit position.

[0068] This embodiment uses a stepper motor to drive the air outlet component 3 to swing. When the air outlet component 3 swings to the first limit position or the second limit position, the limit limit structure restricts the air outlet component 3 from continuing to swing. At this time, it can be identified that the current of the stepper motor increases, and then it is determined that the air outlet component 3 has swung to the first limit position or the second limit position.

[0069] In other embodiments, the method for setting the shaking angle includes the following steps:

[0070] S51, controlling the stepper motor to drive the air outlet assembly 3 to swing from the middle position to the first limit position;

[0071] S52, obtaining the number of steps A of the stepper motor when the air outlet component 3 swings from the middle position to the first limit position;

[0072] S53, setting the shaking angle of the air outlet component 3 to M gears;

[0073] S54, when controlling the Nth gear position, the number of steps of the air outlet assembly 3 swinging left and right from the middle position is N*A / M.

[0074] In this embodiment, the steps of the stepper motor from the middle position to the first extreme position and the second extreme position on the left and right are symmetrically divided according to the number of gears of the shaking head, so as to achieve precise control of the swing angles of the air outlet component 3 at different gears, and realize the equidistant left and right swing of the air outlet component 3 based on the middle position.

[0075] like Figure 2-Figure 4 As shown, the present embodiment also provides a fan, which is applied to the above-mentioned fan shaking angle adjustment method, and the fan includes a shaking assembly 1, a fixed shaft 2, an air outlet assembly 3 and a control assembly 4. The shaking assembly 1 includes a shaking component 11, a driving component 12 and a photoelectric detection switch 13. The photoelectric detection switch 13 and the driving component 12 are both arranged on the shaking component 11, and the photoelectric detection switch 13 is provided with a detection slot 131; the fixed shaft 2 is provided with a baffle 211, and the driving component 12 is used to drive the shaking component 11 to rotate relative to the fixed shaft 2; the air outlet assembly 3 is connected to the shaking component 11, and the air outlet assembly 3 can As the shaking head assembly 1 swings to the first extreme position, the middle position and the second extreme position, the middle position is located between the first extreme position and the second extreme position. When the air outlet assembly 3 swings between the first extreme position and the middle position along with the shaking head assembly 1, the baffle 211 is located in the detection slot 131, and the photoelectric detection switch 13 outputs a first signal; when the air outlet assembly 3 swings between the middle position and the second extreme position along with the shaking head assembly 1, the baffle 211 is located outside the detection slot 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 component 12.

[0076] During the operation of the fan, the control component 4 can obtain 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 slot 131, and the air outlet component 3 swings to between the first extreme position and the middle position with the shaking component 11; when the photoelectric detection switch 13 outputs the second signal, the baffle 211 is located outside the detection slot 131, and the air outlet component 3 swings to between the middle position and the second extreme position with the shaking component 11; when the first signal and the second signal output by the photoelectric detection switch 13 are switched, the air outlet component 3 swings to the middle position with the shaking component 11. The present invention uses the output signal of the photoelectric detection switch 13 to enable the control component 4 to accurately detect the current swing position of the air outlet component 3, and the control component 4 can also control the swing angle of the air outlet component 3 through the driving component 12.

[0077] In this embodiment, the control component 4 includes 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, and 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, does not block the photoelectric detection switch 13, and 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.

[0078] Further, the oscillating component 11 includes a connecting seat 111 and a mounting seat 112 which are connected to each other, the driving component 12 is connected to the connecting seat 111, the air outlet component 3 is connected to the mounting seat 112, the mounting seat 112 is provided with a first through hole 1121, the fixed shaft 2 is passed through the first through hole 1121, and the mounting seat 112 is rotatably connected to the fixed shaft 2. In this embodiment, the photoelectric detection switch 13 is connected to the connecting seat 111, a bearing 113 is provided between the first through hole 1121 and the fixed shaft 2, the mounting seat 112 is rotatably connected to the fixed shaft 2 through the bearing 113, the connecting seat 111 and the mounting seat 112 can be connected by screws, and when the air outlet component 3 swings with the oscillating component 11, the fixed shaft 2 remains stationary.

[0079] Furthermore, the driving component 12 includes a driving member 121 and a driving gear 122. The connecting seat 111 is provided with a connecting hole. The driving member 121 is connected to the connecting hole. The driving member 121 is drivingly connected to the driving gear 122. The top of the fixed shaft 2 is provided with a semi-annular portion 21. A part of the semi-annular portion 21 is a baffle 211, and the other part is provided with a toothed groove 212. The driving gear 122 is meshedly connected to the toothed groove 212. When the driving member 121 drives the driving gear 122 to rotate, the driving gear 122 meshes with the toothed groove 212 for transmission. Since the position of the toothed groove 212 remains unchanged, the driving member 121 and the oscillating member 11 rotate, so that the driving member 12 drives the oscillating member 11 to rotate relative to the fixed shaft 2. In this embodiment, the driving member 121 is a stepping motor.

[0080] In this embodiment, Figure 3-Figure 5 As shown, a receiving groove 1122 is provided at the top of the mounting seat 112, the semi-annular portion 21 is located in the receiving groove 1122, a first stop protrusion 1123 is provided at the bottom of the receiving groove 1122, and two second stop protrusions 213 are provided at intervals on one side of the semi-annular portion 21 close to the 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 component 3 can swing to the first extreme position or the second extreme position along with the shaking head component 1, the first stop protrusion 1123 respectively contacts the two second stop protrusions 213 to prevent the air outlet component 3 from swinging too large. It should be noted that in the design of the swing structure of the air outlet component 3, two second stop protrusions 213 are set, and the two second stop protrusions 213 serve as the limit limiting structures for the left and right swinging of the air outlet component 3. After the air outlet component 3 swings to the first limit position or the second limit position, the swinging will be restricted. At this time, the current of the stepper motor increases. When the air outlet component 3 swings to the limit limiting structure, the control component 4 can detect the current change signal after the stepper motor is restricted, thereby judging that the air outlet component 3 has reached the first limit position or the second limit position.

[0081] In this embodiment, the air outlet assembly 3 includes a cover 31, a fan blade 32 and a fan blade motor. The cover 31 is covered by the fan blade 32 and connected to the mounting seat 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 this embodiment, the control assembly 4 includes at least two buttons 41, and the at least two buttons 41 are used to enable the MCU 42 to 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 respectively when triggered. In this embodiment, the shaking head component 11 also includes an outer cover 114, and the button 41 is arranged at the top of the outer cover 114.

[0082] Furthermore, if Figure 2 and Figure 3As shown, the fan further includes a clamping assembly 5, which includes a knob 51, a connecting member 52 and a clamping member 53.

The knob 51 is penetrated 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 spacing between the opposite side walls of the hinge groove. The fan can be clamped at a preset position by the first end of the clamping member 53, which is convenient for fixing the 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 side walls opposite to the hinge groove is reduced, and the side walls opposite to 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 preset pitch angle of the air outlet component 3.

[0083] 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 .
