[0003] Traditional fans are started directly with high current, but even if the fan is driven with high current, the fan may not be able to break the ice.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] like Figures 1 to 6At least one embodiment provides an intelligent control device for a fan, which includes: a controller and an electromagnetic component 1; wherein the electromagnetic component 1 is located between a fan unit 23 and a shell 21 in a fan component 2, and the electromagnetic component 1 is connected to the fan unit 23; the electromagnetic component 1 is electrically connected to the controller; when the fan component 2 fails to start, the controller drives the electromagnetic component 1 to energize to heat the fan component 2 to melt the attachments on the fan unit 23 and the obstacles on the inner wall of the shell 21, and the controller drives the motor unit 22 in the fan component 2 to reciprocate and swing the fan unit 23 within a set angle range until the output signal of the controller is consistent with the feedback signal, and the controller drives the motor unit 22 to rotate the fan unit 23 normally.

[0029] Specifically, when most of the fan unit 23 in the fan assembly 2 is covered or frozen, the motor unit 22 cannot drive the fan unit 23 to rotate. At this time, the motor unit 22 sends a feedback signal to the controller, that is, the fan assembly 2 fails to start. At this time, the controller drives the electromagnetic assembly 1 to continue to be energized, and the electromagnetic assembly 1 will generate heat, thereby heating the fan unit 23 and the shell 21, so that the attachments on the fan unit 23 and the obstacles on the inner wall of the shell 21 gradually melt. When the controller drives the motor unit 22 to try to drive the fan unit 23 to rotate, the controller sends an output signal to the motor unit 22, that is, to rotate the set angle within the set time. Then the motor unit 22 sends a feedback signal to the controller, indicating the actual rotation angle within the set time, and gradually increases the set angle until the rotation angle within the set time is equal to the actual rotation angle within the set time, that is, the output signal of the controller is consistent with the feedback signal. At this time, the controller can accurately control the motor unit 22, and finally the controller drives the motor unit 22 to rotate the fan unit 23 normally.

[0030] In at least one embodiment, by arranging the electromagnetic component 1 on the fan assembly 2, when the fan assembly 2 is covered with snow or frozen, the electromagnetic component 1 generates heat, which can melt the attachments on the fan unit 23 and the obstacles on the inner wall of the shell 21, thereby overcoming the problem of the fan being damaged under continuous large current, and repeatedly debugging before the fan assembly 2 starts normally until the fan assembly 2 meets the control accuracy and starts normally, thereby improving the control accuracy and operation safety.

[0031] In at least one embodiment, when the fan assembly 2 is blocked from starting, the controller drives the motor unit 22 to accelerate the rotation of the fan unit 23 to clean the attachments on the fan unit 23 and the obstructions on the inner wall of the shell 21; when the controller drives the motor unit 22 to slow down the rotation of the fan unit 23, the controller drives the electromagnetic assembly 1 to energize so that the electromagnetic assembly 1 generates suction to the shell 21, thereby hindering the rotation of the fan unit 23 until the set speed is reached.

[0032] Specifically, when a small part of the fan unit 23 in the fan assembly 2 is covered, the motor unit 22 can drive the fan unit 23 to rotate. That is, at this time, the controller sends an output signal to the motor unit 22, that is, sets the set rotation speed of the motor unit 22. At this time, the motor unit 22 sends a feedback signal to the controller, that is, the actual rotation speed of the motor unit 22. However, the actual rotation speed is not equal to the set rotation speed. At this time, the controller determines that the start-up of the fan assembly 2 is obstructed, and drives the motor unit 22 to accelerate the rotation of the fan unit 23 through the controller, so as to throw out the attachments on the fan unit 23 or scrape off the obstacles on the inner wall of the shell 21.

[0033] Specifically, since there may be attachments on the fan unit 23, the controller cannot accurately control the motor unit 22 to drive the fan unit 23 to rotate. When the controller drives the motor unit 22 to slow down, the fan unit 23 is definitely overweight due to the attachments. If the motor unit 22 is driven only by the controller, there is a risk of loss of control. By driving the electromagnetic component 1 to be continuously energized by the controller, the electromagnetic component 1 will generate a magnetic field, that is, the electromagnetic component 1 generates suction on the shell 21, which can provide additional resistance to the fan unit 23, offset the additional gravity on the fan unit 23, and thereby eliminate the risk of loss of control.

[0034] In at least one embodiment, the electromagnetic component 1 includes: a plurality of electromagnetic modules 11; each of the electromagnetic modules 11 is respectively arranged on the fan unit 23, and each of the electromagnetic modules 11 is electrically connected to the controller; when the controller obtains a feedback signal and senses that the motor unit 22 fails to start, the controller drives each of the electromagnetic modules 11 to be powered on for heating to melt the attachments on the fan unit 23 and the obstacles on the inner wall of the shell 21; when the controller drives the motor unit 22 to reduce the speed of the fan unit 23, the controller drives each of the electromagnetic modules 11 to be powered on so that each of the electromagnetic modules 11 generates suction to the shell 21.

[0035] Specifically, the electromagnetic module 11 generates heat when powered on, which can melt the attached objects on the fan unit 23 and the blocking objects on the inner wall of the housing 21 .

[0036] Specifically, the electromagnetic module 11 is energized to generate a magnetic field, and the fan unit 23 is braked by suction.

[0037] In at least one embodiment, each electromagnetic module 11 is electrically connected to the slip ring inside the motor unit 22; when the motor unit 22 and each electromagnetic module 11 are powered on at the same time, the motor unit 22 is divided by each electromagnetic module 11 to reduce the rotation speed of the motor unit 22.

[0038] Specifically, the electromagnetic module 11 and the motor unit 22 are powered by slip rings, so that each electromagnetic module 11 is connected in series with the motor unit 22. When the motor unit 22 is decelerating, each electromagnetic module 11 can divide the voltage, thereby reducing the voltage on the motor unit 22 and improving the speed reduction effect of the motor unit 22.

[0039] In at least one embodiment, the electromagnetic module 11 includes: an electromagnet 111; the electromagnet 111 is arranged in a strip or sheet shape, the electromagnet 111 is connected to the fan unit 23, and the electromagnet 111 is electrically connected to the controller; a magnetic metal layer 211 is arranged on the inner wall of the shell 21, and the electromagnet 111 is located next to the magnetic metal layer 211.

[0040] Specifically, the electromagnet 111 can generate heat and a magnetic field when powered on, and cooperate with the magnetic metal layer 211 to provide a braking force on the fan unit 23 .

[0041] Based on the same technical concept, at least one embodiment also provides a control system, which includes: a controller, a fan assembly 2 and an electromagnetic assembly 1; wherein the electromagnetic assembly 1 is located between the fan unit 23 and the shell 21 in the fan assembly 2, and the electromagnetic assembly 1 is connected to the fan unit 23; the electromagnetic assembly 1 is electrically connected to the controller; when the fan assembly 2 fails to start, the controller drives the electromagnetic assembly 1 to energize and heat the fan assembly 2 to melt the attachments on the fan unit 23 and the obstacles on the inner wall of the shell 21, and the controller drives the motor unit 22 in the fan assembly 2 within a set angle range The fan unit 23 is swung back and forth until the output signal of the controller is consistent with the feedback signal, and the controller drives the motor unit 22 to rotate the fan unit 23 normally; when the start-up of the fan assembly 2 is blocked, the controller drives the motor unit 22 to accelerate the rotation of the fan unit 23 to clean the attachments on the fan unit 23 and the obstructions on the inner wall of the shell 21; when the controller drives the motor unit 22 to reduce the speed of the fan unit 23, the controller drives the electromagnetic assembly 1 to energize, so that the electromagnetic assembly 1 generates suction to the shell 21, thereby hindering the rotation of the fan unit 23 until the set speed is reached.

[0042] Specifically, the controller cooperates with the fan assembly 2 and the electromagnetic assembly 1 to achieve closed-loop control.

[0043] In at least one embodiment, the fan assembly 2 includes: a housing 21, a motor unit 22 and a fan unit 23; the motor unit 22 is installed in the housing 21, the fan unit 23 is movably connected to the motor unit 22, and the motor unit 22 is electrically connected to the controller; the controller sends a corresponding output signal to the motor unit 22 so that the motor unit 22 rotates according to the output signal; the motor unit 22 obtains rotation data and forms a corresponding feedback signal to send to the controller.

[0044] In at least one embodiment, the motor unit 22 includes: a motor drive module and a rotating motor 221; the rotating motor 221 is electrically connected to the motor drive module, and the rotating motor 221 is installed in the shell 21; the motor drive module is electrically connected to the controller; the controller sends a corresponding output signal to the motor drive module, so that the motor drive module drives the rotating motor 221 to rotate according to the output signal; the motor drive module collects the rotation data of the rotating motor 221 to form a corresponding feedback signal and send it to the controller; the fan unit 23 includes: a rotating shaft 231 and a plurality of fan blades 232; one side of the rotating shaft 231 is connected to the rotating motor 221, and each of the fan blades 232 is circumferentially arranged on the other side of the rotating shaft 231; the rotating motor 221 drives the rotating shaft 231 and each fan blade 232 to rotate.

[0045] Specifically, the motor driving module plays a role in driving the rotating motor 221 on the one hand, and can feed back the state of the rotating motor 221 to the controller on the other hand.

[0046] In at least one embodiment, the electromagnetic assembly 1 includes: a plurality of electromagnetic modules 11; each of the electromagnetic modules 11 is respectively arranged at the distal end of the corresponding fan blade 232, and each of the electromagnetic modules 11 is electrically connected to the controller; when the controller obtains a feedback signal and senses that the rotating motor 221 fails to start, the controller drives each electromagnetic module 11 to energize to heat the fan assembly 2 to melt the attachments on each of the fan blades 232 and the obstacles on the inner wall of the shell 21; when the controller drives the rotating motor 221 to reduce the speed of each fan blade 232 through the motor drive module, the controller drives each electromagnetic module 11 to energize so that each of the electromagnetic The module 11 generates suction force on the shell 21; each electromagnetic module 11 is electrically connected to the slip ring inside the rotating motor 221; when the rotating motor 221 and each electromagnetic module 11 are energized at the same time, the rotating motor 221 is divided by each electromagnetic module 11 to reduce the rotation speed of the rotating motor 221; the electromagnetic module 11 includes: an electromagnet 111; the electromagnet 111 is arranged in a strip or sheet shape, the electromagnet 111 is connected to the distal end of the fan blade 232, and the electromagnet 111 is electrically connected to the controller; a magnetic metal layer 211 is arranged on the inner side wall of the shell 21, and the electromagnet 111 is located next to the magnetic metal layer 211.

[0047] Based on the same technical concept, at least one embodiment also provides a control method using a control system as described above, which includes: when the fan assembly 2 fails to start, the controller drives the electromagnetic assembly 1 to energize for heating to melt the attachments on the fan unit 23 and the obstructions on the inner wall of the shell 21, and the controller drives the motor unit 22 in the fan assembly 2 to swing the fan unit 23 back and forth within a set angle range until the output signal of the controller is consistent with the feedback signal, and the controller drives the motor unit 22 to rotate the fan unit 23 normally; when the fan assembly 2 is blocked from starting, the controller drives the motor unit 22 to accelerate the rotation of the fan unit 23 to clean the attachments on the fan unit 23 and the obstructions on the inner wall of the shell 21; when the controller drives the motor unit 22 to reduce the speed of the fan unit 23, the controller drives the electromagnetic assembly 1 to energize so that the electromagnetic assembly 1 generates suction to the shell 21, thereby hindering the rotation of the fan unit 23 until the set speed is reached.
