[0002] With the development of technology, people have higher requirements for product experience, especially for the intelligent processing of products. Currently, the circulating fans on the market have a shaking head function. In order to meet the aesthetics of the whole fan in the end state, after starting the shaking head of the fan and entering the standby state, the function of returning the shaking head of the fan to the correct position is started, and the fan head is swung to the front of the whole fan. However, some users need to fix the shaking head angle of the fan to blow air when the whole fan does not move, but each time the fan is turned off, the function of returning to the correct position will be executed. When the user turns it on again, the shaking head angle needs to be readjusted and fixed, which cannot meet the user's needs, the logical judgment is not intelligent enough, and the user experience is poor.

[0038] Figure 1 The flowchart of a fan return control method according to an embodiment of the present invention is schematically shown. Referring to Figure 1 , the fan return control method according to the embodiment of the present invention specifically includes the following steps:

[0039] S11. Determine the shaking execution mode when the fan turns on the shaking function;

[0040] In this embodiment, the shaking function includes: turning on the up-and-down or left-and-right shaking function and having a functional action with a cyclic sweeping angle.

[0041] S12. If the shaking execution mode is a single shaking function, detect the angle change information of the fan in the second direction when executing the shaking function in the first direction;

[0042] Further, the single shaking function is a left-and-right shaking function or an up-and-down shaking function;

[0043] The first direction is the left-and-right direction or the up-and-down direction. When the first direction is the left-and-right direction, the second direction is the up-and-down direction. When the first direction is the up-and-down direction, the second direction is the left-and-right direction.

[0044] Further, the method further includes: when the fan does not turn on the shaking function and only turns on the wind speed gear adjustment function, no return operation is performed when the fan shuts down.

[0045] Further, the method further includes: if the shaking execution mode is that both the up-and-down shaking function and the left-and-right shaking function are turned on, a return operation is performed when the fan shuts down.

[0046] Further, the detecting the angle change information of the fan in the second direction when executing the shaking function in the first direction includes:

[0047] Detect the amplitude and frequency of angle change of the fan in the second direction within a preset time duration when the fan performs the head - shaking function in the first direction.

[0048] In this embodiment, a sensor can be used to detect the angle of the fan in the second direction within a preset time duration when the fan performs the head - shaking function in the first direction. The sensor can be arranged on the fan column or the head - shaking component; the head - shaking drive motor can be a stepper motor; the fan has two drive power supplies, one is the drive power supply for head - shaking, and the other is the power supply for the fan motor.

[0049] In this embodiment, if the head - shaking execution mode is that both the up - and - down head - shaking function and the left - and - right head - shaking function are turned on, it is determined that the user has no need to blow air at a specific position, and an automatic alignment operation is performed when the fan is turned off.

[0050] S13. Determine whether the angle change information meets the preset angle fine - tuning control condition;

[0051] Further, determining whether the angle change information meets the preset angle fine - tuning control condition includes:

[0052] When the fan continuously has angle fine - tuning control operations with the amplitude of angle change less than or equal to the preset angle threshold in the second direction for n times, it is determined that the angle change information meets the preset angle fine - tuning control condition; otherwise, it is determined that the angle change information does not meet the preset angle fine - tuning control condition; n is greater than the preset number threshold.

[0053] In this embodiment, the preset number threshold can be 5 times.

[0054] S14. If the angle change information does not meet the preset angle fine - tuning control condition, perform an alignment operation when the fan is turned off.

[0055] Further, the method further includes: if the angle change information meets the preset angle fine - tuning control condition, do not perform an alignment operation when the fan is turned off.

[0056] In this embodiment, detect the amplitude and frequency of angle change of the fan in the second direction when the fan performs the head - shaking function in the first direction. If there is no angle change, perform an automatic alignment operation when the fan is turned off.

[0057] In this embodiment, detect the amplitude and frequency of angle change of the fan in the second direction within a preset time duration when the fan performs the head - shaking function in the first direction, start the fixed fine - tuning azimuth angle function, perform fine - tuning control on the left - right or up - down direction angle of the fan, and determine whether to perform an automatic alignment operation when the fan is turned off by fine - tuning the size area of the azimuth sweeping angle.

[0058] In this embodiment, a special logic fan model is involved. The functions of this type of model are different from those of the models with the up / down or left / right swing functions, and it has a special function technology for fixing and finely adjusting the orientation angle. By the user turning on the up / down or left / right swing function and adjusting the position at another angle without swinging, if it is detected that the angle without the swing action does not change for a continuous period of time, it is intelligently determined that the fan does not return to the upright position when turned off, meeting the user's experience requirements.

[0059] In this embodiment, the amplitude and frequency of the angle change of the fan in the second direction when performing the swing function in the first direction are detected. If it is detected that the amplitude of the angle change A≤10° in the up / down or left / right direction occurs more than 5 times continuously, it is determined that the user has a need for blowing air at a specific position, and the fan does not perform the return-to-upright operation when turned off; if it is detected that the amplitude of the angle change A≤10° or A>10° in the up / down or left / right direction occurs no more than 5 times continuously, the fan performs the automatic return-to-upright operation when turned off.

[0060] For example, when the user is using a circulation fan and turns on the up / down swing function, the user adjusts the angle position of the left / right swing. During the working process, it is detected that the amplitude of the angle change A = 5° in the direction occurs 6 times continuously. It is determined that the user has a need for a specific position, and the fan does not perform the automatic return-to-upright operation when turned off, meeting the experience of some users.

[0061] In this embodiment, turning off refers to the overall shutdown of the fan, rather than the shutdown of the swing component. The reset key of the swing component can have a drop-down menu, which includes: left / right centered, up / down centered, etc. for the user to select.

[0062] A fan return-to-upright control method provided by an embodiment of the present invention detects the rotation angle of the fan when turning on a single swing function and a special function for fixing and finely adjusting the orientation angle according to the swing execution method when the fan turns on the swing function. By analyzing the angle change information of the fan in the second direction when performing the swing function in the first direction, it is determined whether the user needs air supply at a specific position, so as to judge whether the fan performs the return-to-upright operation when turned off, more intelligently realizing the return-to-upright control of the fan, meeting the user's usage habits, and improving the user experience.

[0063] Figure 2 It is a flowchart of another fan return-to-upright control method provided by an embodiment of the present invention. As Figure 2As shown, determine the shaking execution mode when the fan turns on the shaking function; if the shaking execution mode is a single shaking function, detect the angle change amplitude and angle change frequency of the fan in the second direction within a preset time period when executing the shaking function in the first direction; when the fan continuously has n angle fine-tuning control operations in the second direction with the angle change amplitude less than or equal to the preset angle threshold, determine that the angle change information meets the preset angle fine-tuning control condition, otherwise determine that the angle change information does not meet the preset angle fine-tuning control condition; the n is greater than the preset number threshold; if the angle change information does not meet the preset angle fine-tuning control condition, perform a straightening operation when the fan shuts down; if the angle change information meets the preset angle fine-tuning control condition, do not perform a straightening operation when the fan shuts down; when the fan does not turn on the shaking function and only turns on the wind speed gear adjustment function, do not perform a straightening operation when the fan shuts down; if the shaking execution mode is that both the up-and-down shaking function and the left-and-right shaking function are turned on, perform a straightening operation when the fan shuts down.

[0069] The execution module 304 is used to perform a straightening operation when the fan shuts down when the angle change information does not meet the preset angle fine-tuning control condition.

[0070] Furthermore, the single shaking function is a left-and-right shaking function or an up-and-down shaking function;

[0071] The first direction is the left - right direction or the up - down direction. When the first direction is the left - right direction, the second direction is the up - down direction; when the first direction is the up - down direction, the second direction is the left - right direction.

[0072] Further, the device further includes a configuration module not shown in the drawings. When the fan does not turn on the swing function but only turns on the air volume adjustment function, the configuration module does not perform the straightening operation when the fan is turned off.

[0073] Further, the device further includes a configuration module not shown in the drawings.
