[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] Head shaking is a common function of a fan, and with the improvement of user experience and the demand of use scenarios, the setting of the head shaking angle becomes an indispensable part. Most of the control of the fan is through user operation control instructions to drive the head shaking motor to continuously shake and blow, if the user needs the head shaking mechanism to stop at different positions, the user needs to observe the head shaking mechanism running to the corresponding position and then operate the control instruction to turn off the head shaking motor to achieve it. Moreover, the fan cannot blow based on the user's position during the head shaking blowing process, and the range of the head shaking blowing is too large. Obviously, the fan in such a head shaking blowing use process will cause the user's experience to be poor.

[0023] In order to solve the above-mentioned problems of the fan, the present application first proposes a control method of a fan, which is applied to a fan. The fan includes a head shaking mechanism, and a plurality of receiving devices are arranged at different positions of the head shaking mechanism. In the present embodiment, the head shaking mechanism of the fan can be the upper air outlet part of a bladeless fan, or the fan head of a floor fan, or the moving part of the head shaking driving mechanism, which is not limited here. Please refer to Figure 1 , Figure 1 is a flowchart of a first embodiment of the control method of the fan of the present application. As shown in Figure 1 , the control method of the fan of the present embodiment specifically includes steps S101 to S103:

[0024] Step S101: Determine whether the receiving device has received a control signal, wherein the control signal includes multiple data frames.

[0025] In this embodiment, multiple receiving devices are installed at different positions on the fan's oscillation mechanism, and the receiving devices are connected to the fan's controller. In this application, the receiving devices can be installed at equal angles according to the air delivery range of the oscillation mechanism. In other embodiments, the receiving devices can also be installed on the fan body according to the air delivery range of the oscillation mechanism; this is not a limitation.

[0026] When a user controls the fan using an infrared remote control, a control signal is sent to the receiver on the oscillation mechanism. In this embodiment, the control signal may include multiple data frames; that is, each time the user presses a button on the remote control, the remote control will continuously transmit multiple identical data frames. When the controller controls the fan, it first needs to determine whether the receiver has received such a control signal.

[0027] Step S102: In response to multiple receiving devices receiving control signals, determine user location information based on the data frames received by the receiving devices.

[0028] If multiple receivers on the oscillating mechanism receive control signals from the remote control, the user's position information can be determined based on the data frames received by the receivers. In other words, the fan controller combines the data from the multiple receivers and the order in which the control signals were received to determine the user's position information.

[0029] Optionally, in this embodiment, the method for determining user location information based on the data frames received by the receiving device can be to determine user location information based on the number of data frames received by the receiving device.

[0030] Because the receiving devices are installed at equal angles to the airflow range of the oscillating mechanism, the number of data frames received by each receiving device per unit time may differ due to the angle. If the number of data frames received by each receiving device per unit time is different, the orientation of the receiving device that receives the most data frames is the user's position. Based on this, the user's position information when operating the remote control to transmit control signals can be determined.

[0031] Step S103: Control the oscillating mechanism to deliver airflow based on the user's location information.

[0032] After obtaining the user's location information based on the control signal as described above, the fan controller can control the oscillation mechanism to deliver airflow based on the user's location information.

[0033] For example, when the fan is in the spot blowing mode, the user position information can be used as the center point of the head-shaking blowing to remotely blow air to the user based on the head-shaking control instruction and the user position information. When the fan is in the head-shaking blowing mode, the fan can be controlled to move to the user position to blow air to the user based on the spot control instruction and the user position information.

[0034] Different from the prior art, the fan control method of the application can determine the user position information based on the data frames received by the receiving devices in response to the control signals being received by the receiving devices, and control the head-shaking mechanism to blow air based on the user position information. Through the above method, the fan control method of the application can more accurately obtain the user position information based on the data frames received by the receiving devices, thereby more accurately blowing air to the user, and improving the blowing effect of the fan head-shaking blowing and the user experience.

[0035] As shown in Figure 2 , please refer to Figure 2 , Figure 2 is Figure 1 a flowchart of a specific embodiment of step S102. The embodiment can implement the step of determining the user position information based on the number of data frames received by the receiving devices through the method as shown in Figure 2 , and the specific implementation steps include steps S201 to S203:

[0036] Step S201: Determine whether the number of data frames received by all the receiving devices that receive the data frames is the same.

[0037] Since the receiving devices are installed at equal angles in combination with the blowing range of the head-shaking mechanism, the number of data frames of the control signals received by each receiving device in a unit time may be different due to the angle problem when receiving the control signals of the remote controller.

[0038] After the judgment processing, the controller of the fan can obtain all the control signals after determining that the obtained infrared signals come from a plurality of specific infrared receiving heads, and determine whether the number of data frames received by all the receiving devices that receive the data frames is the same.

[0039] If the number is different, step S202 is performed; if the number is the same, step S203 is performed.

[0040] Step S202: Perform the step of determining the user position information based on the number of data frames received by the receiving devices.

[0041] In response to the number of data frames received by all the receiving devices being different, the step of determining the user position information based on the number of data frames received by the receiving devices is performed. That is, the position of the receiving device that receives the largest number of data frames in a unit of time is obtained, and the user position information can be obtained based on the position of the receiving device that receives the largest number of data frames.

[0042] Step S203: determining the user position information based on the order of the data frames received by the receiving devices.

[0043] In response to the number of data frames received by all the receiving devices being the same, the control system of the fan can determine the user position information based on the order of the data frames received by the receiving devices. That is, the controller obtains the position information of the receiving device that first receives the data frame of the control signal, and the user position information can be obtained based on the orientation of the receiving device.

[0044] Compared with the prior art, the fan control method of the application can more accurately determine the position of the user and obtain the user position information by judging the order of receiving the control signal and the number of data frames of receiving the infrared emission signal, which is beneficial to improving the air supply efficiency of the fan and improving the convenience and intelligence of the fan use.

[0045] Optionally, referring to Figure 3 , Figure 3 is Figure 1 a flowchart of a specific implementation of step S103 in the embodiment. The embodiment can implement step S103 by the method shown in Figure 3 , and the specific implementation steps include steps S301 to S302.

[0046] Step S301: obtaining the working state of the head-rotating mechanism.

[0047] After obtaining the user position information, the controller of the fan can obtain the current working state of the head-rotating mechanism before controlling the head-rotating mechanism to perform fan air supply based on the user position information.

[0048] Step S302: controlling the head-rotating mechanism to perform fan air supply based on the working state and the user position information.

[0049] The controller of the fan can control the head-rotating mechanism to perform fan air supply based on the working state and the user position information.

[0050] Specifically, in response to the working state being the head-rotating state, the head-rotating mechanism is controlled to perform fan head-rotating air supply with the position corresponding to the user position information as the center point.

[0051] That is, if the working state of the fan is the oscillating blowing state, at this time, if the receiving device on the oscillating mechanism receives the control signal of the user setting the angle of oscillation, the controller of the fan will obtain the user position information based on the method described above through the control signal, and the oscillating blowing is performed with the position corresponding to the user position information as the midpoint, thereby improving the blowing effect of the fan oscillating blowing.

[0052] In response to the working state being the non-oscillating state, the oscillating mechanism is controlled to move to the position corresponding to the user position information for the fan to perform the spot blowing.

[0053] When the fan is in the non-oscillating state, if the receiving device on the oscillating mechanism receives the control signal of the user setting the spot blowing, the controller of the fan will obtain the user position information based on the method described above through the control signal, and the control instruction corresponding to the position of the user position information is transmitted to the driving motor of the oscillating mechanism, the oscillating motor drives the fan to move in the position direction of the signal sent by the user, if the oscillating mechanism moves to the position of the control signal sent by the user, the driving motor is automatically stopped, and the fan blows at this position to the user.

[0054] In the prior art, if the user needs to perform the spot blowing, the general way is to turn on the oscillating function of the fan, wait for the fan to oscillate to the position of the user, and then turn off the oscillating function to stop the spot blowing at the position of the user. Different from the prior art, the above-mentioned method can reduce the operation of the user's spot blowing, and improve the convenience and intelligence of the fan.

[0055] Optionally, please refer to Figure 4 , Figure 4 is the flowchart of the second embodiment of the control method of the fan. As shown in the figure, the control method of the fan of the embodiment specifically includes steps S401 to S404:

[0056] Step S401: judging whether the receiving device receives the control signal, wherein the control signal includes a plurality of data frames.

[0057] Step S401 is the same as step S101, and will not be described again.

[0058] Step S402: in response to only one receiving device receiving the control signal, judging whether the received control signal is valid.

[0059] If only one receiving device of the oscillating mechanism receives the control signal of the remote controller, at this time, the controller of the fan needs to judge whether the received control signal is valid.

[0060] If valid, go to step S403.

[0061] Step S403: determining the user position information based on the position information of the receiving device receiving the control signal.

[0062] If the control signal is valid, the controller of the fan can determine the user position information based on the position information of the only receiving device receiving the control signal.

[0063] Step S404: controlling the swing mechanism to blow air by the fan based on the user position information.

[0064] Step S404 is consistent with step S103, and will not be described again.

[0065] In an application scenario, please refer to Figure 5 , Figure 5 is a flowchart of a specific embodiment of the fan control method of the present application. As shown in Figure 5 , the embodiment specifically includes steps S501 to S504:

[0066] Step S501: the receiving device starts to work and acquires the control signal.

[0067] Step S502: determining whether the receiving device receives the control signal.

[0068] The user operates the remote controller to emit the control signal, and the receiving device arranged on the swing mechanism receives the control signal. The controller of the fan determines whether the receiving device receives the control signal.

[0069] If yes, go to step S503, and if no, go back to step S502.

[0070] Step S503: determining whether only one receiving device receives the control signal.

[0071] If only one, go to step S504; if not only one, go to step S505.

[0072] Step S504: determining whether the control signal received by the receiving device is valid.

[0073] If valid, go to step S506, and if invalid, go to step S501.

[0074] Step S505: determining the user position information based on the color number, frame number and sequence of the control signal received by all receiving devices.

[0075] Step S506: acquiring the user position information based on the position information of the only receiving device receiving the control signal.

[0076] Step S507: controlling the swing mechanism to blow air by the fan based on the user position information.

[0077] If the working state of the fan is the oscillating air supply state, at this time, the controller of the fan takes the position corresponding to the user position information as the midpoint for oscillating air supply; if the fan is in a non-oscillating state, the controller of the fan will deliver the control instruction corresponding to the position of the user position information to the drive motor of the oscillating mechanism, and the oscillating motor drives the fan to move in the position direction of the signal sent by the user for point air supply.
