Description

Technical Field

[0001] This application relates to the field of household appliances, and more particularly to a fan and a method for controlling the fan thereto. Background Technology

[0002] Currently, the smart home industry is maturing, and smart fans have stood out among environmental products, gaining popularity among consumers. Most existing smart fans are equipped with functions such as up-and-down and left-and-right oscillation of the fan head, and can also be called circulation fans. Currently, most circulation fans connect the fan head load and the base via wiring harnesses, enabling the base to control the fan head.

[0003] However, using the above-mentioned wiring harness connection method will cause the following problems. On the one hand, the wire may be scratched during the oscillation of the fan head, affecting the operation of the fan. On the other hand, in order to better realize the control of the fan head by the base, the wiring harness will be increased accordingly. The increase of wiring harness not only increases the cost, but also increases the difficulty of production and processing. In addition, in order to meet the wire output requirements, the structural slot for the fan head oscillation is large, which may cause users to be pinched or scratched when they come into contact with the inside of the fan guard during the use of the fan. There is an urgent need for improvement. Summary of the Invention

[0032] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0033] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0034] The terms “first,” “second,” etc., used in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0036] Figure 1This is a schematic diagram of the structure of a smart fan; for example... Figure 1 As shown, the fan may include: a fan base, a fan head, and a structural support connecting the fan base and the fan head.

[0037] For example, the fan head can be connected to the fan base via two structural brackets on the left and right. The front and rear grilles of the fan head are typically made of plastic, while the structural brackets are made of a material that meets rigidity requirements to support the fan head, such as plastic or metal. By slotting the rear grille of the fan head and installing a wiring harness to control the fan head, multiple functions, including the up-and-down oscillation of the fan head, are achieved. The motor inside the fan base drives a connecting rod to achieve the left-and-right oscillation function of the fan. During the oscillation of the circulating fan head, there may be issues with wire snagging. Furthermore, to accommodate the wiring harness exit, the structural slots in the oscillation area cannot be made too small, potentially causing accidental injury to the user due to contact with the inside of the fan grille during fan use.

[0038] Based on this, the following embodiments of the present invention are proposed.

[0039] Figure 2 This is a schematic diagram of the fan's structural composition according to an embodiment of the present invention; combined with Figure 1 and Figure 2 As shown, the fan 10 includes: a first control component 21 and a signal transmitting module 22 disposed within the fan base 11; and a second control component 23, a signal receiving module 24, and a load component 25 disposed within the fan head 13. The fan base 11 and the fan head 13 are fixedly connected by a metal bracket 12, which can transmit power supply signals to power the second control component 23 and the load component 25.

[0040] The first control component 21 is used to acquire the user's first operation information and send the first operation information through the signal transmission module 22;

[0041] The second control component 23 is used to receive the first operation information through the signal receiving module 24, and control the load component 25 to run or stop running according to the first operation information.

[0042] In this embodiment, the fan body includes a fan head 13, a fan base 11, and a metal bracket 12 connecting the fan head and the fan base. The fan base 11 is provided with a first control component 21 and a signal transmitting module 22. The fan head 13 is provided with a second control component 23, a signal receiving module 24, and a load component 25.

[0043] Specifically, the fan head 13 includes fan blades and a mesh cover that surrounds the fan blades. The mesh cover of the fan head 13 can be made of non-conductive plastic. The fan head 13 contains a second control component 23, a signal receiving module 24, and a load component 25. The load component 25 is used to implement some functions of the fan, such as a main motor (or a first motor), which drives the fan blades to rotate to achieve the blowing function; or an oscillating motor (or a second motor), which drives the fan head to oscillate up and down to achieve the fan's oscillation function, etc. That is, the corresponding functions of the fan head can be achieved by controlling the load component 25 through the second control component 23.

[0044] In this embodiment, the metal bracket 12 is a structural bracket made of metal. On one hand, it supports the fan head; on the other hand, utilizing its metallic properties, it transmits power signals to power the second control component 23 and the load component 25 within the fan head. One end of the metal bracket 12 is connected to the output terminal of the power module within the fan base 11. The metal bracket 12 penetrates the top of the fan base 11, passes through the mesh portion of the fan head 13, and is fixedly connected to the structural components within the fan head 13. Furthermore, the metal bracket 12 is electrically connected to the second control component 23 and the load component 25 via multiple contacts, thereby supplying power to both components. This replaces the traditional wire harness power supply method, reducing the need for control wire routing.

[0045] In this embodiment, the fan base can be made of non-conductive plastic material, and a first control component 21 and a signal transmission module 22 are provided inside the fan base; the first control component 21 serves as the master control terminal, and can send operation information to the second control component 23 so that the second control component 23 can control the fan head to achieve various functions based on the operation information.

[0046] In this embodiment, the first control component 21 located on the fan base serves as the main control component. It needs to first acquire the user's first operation information. This first operation information can be control information (i.e., UI information) set by the user and collected by the first control component 21 through the user interface (UI) on the front of the fan base. In practical applications, the UI panel can be located on the front of the fan base 11, and the first control component 21 is electrically connected to the UI panel. For example, the first control component 21 can detect the operation buttons triggered by the user on the UI panel and identify the operation information (including the first operation information) corresponding to the operation buttons.

[0047] In this embodiment, the first operation information is operation information corresponding to the function of the fan head. For example, the first operation information may include user-set fan speed level, oscillation mode and frequency, timing, etc. After obtaining the first operation information, the first control component 21 sends the first operation information through the signal transmitting module 22 located on the fan base, so as to control the fan head to realize the fan-related functions corresponding to the settings entered by the user in the UI panel. After the first control component 21 sends the first operation information, the second control component 23 located on the fan head receives the first operation information through the signal receiving module 24, and controls the start or stop of the load component 25 located on the fan head 13 according to the first operation information, so as to realize the corresponding function of the fan head based on the first operation information.

[0048] In some alternative embodiments, the signal transmitting module 22 is disposed at the top of the fan base 11, and the signal receiving module 24 is disposed in the lower part of the fan head 13, with the signal transmitting range of the signal transmitting module 22 corresponding to the signal receiving range of the signal receiving module 24.

[0049] In this embodiment, a signal transmitting module 22 and a corresponding signal receiving module 24 are respectively provided on the fan base 11 and the fan head 13 to realize information transmission between the first control component 21 in the fan base 11 and the second control component 23 in the fan head 13.

[0050] For example, in this embodiment of the invention, the signal transmitting module 22 can be an infrared transmitting module, and the signal receiving module 24 can be an infrared receiving module, that is, information is transmitted via infrared. Furthermore, the signal transmission range of the signal transmitting module 22 needs to correspond to the signal receiving range of the signal receiving module 24, so that the signal receiving range of the signal receiving module 24 completely or partially includes the signal transmission range of the signal transmitting module 22. This ensures that the signal transmitted by the signal transmitting module 22 can be completely received by the signal receiving module 24, or that the signal transmitting module 22 can transmit a signal according to a portion of the corresponding receiving range of the signal receiving module 24, thereby ensuring the stability of the infrared information transmission. For example, the signal transmitting module 22 and the signal receiving module 24 can be arranged facing each other. Specifically, the signal transmitting module 22 can be placed at the axial center position at the top inside the fan base 11, and the signal receiving module 24 can be placed at the axial center position at the bottom inside the fan head 13, that is, keeping the transmitting tube of the signal transmitting module 22 and the receiving tube of the signal receiving module 24 facing each other. In addition, the infrared pair can also be replaced with radio frequency transmission and reception to achieve wireless communication. In other alternative embodiments, the signal transmitting module 22 and the signal receiving module 24 may also use other wireless transmission methods to transmit operation information, such as Bluetooth, Zigbee, etc. This embodiment does not specifically limit the wireless transmission method used by the signal transmitting module 22 and the signal receiving module 24.

[0051] In this embodiment, taking the infrared transmission method of the signal transmitting module 22 and the signal receiving module 24 as an example, the first control component 21 sends the first operation information to the signal transmitting module 22 in the form of an electrical signal. The signal transmitting module 22 needs to convert the electrical signal carrying the first operation information into an infrared signal and send the converted infrared signal carrying the first operation information to the signal receiving module 24 in the fan head 13. After receiving the infrared signal carrying the first operation information, the signal receiving module 24 converts the infrared signal into an electrical signal and then transmits the electrical signal carrying the first operation information to the second control component 23, so that the second control component 23 controls the load component 25 based on the first operation information.

[0052] In this embodiment of the invention, by using a wireless transmission method with signal transmitting module 22 and signal receiving module 24, the first operation information obtained by the first control group 21 is sent to the second control component 23 wirelessly, achieving true wireless isolation and preventing mutual interference. Wireless control reduces the number of wires threaded through the harness, thereby reducing the overall thickness of the bracket and the width of the slot in the rear mesh cover, reducing the risk of accidental injury caused by the user's fingers being inserted into the slot, and enhancing safety performance.

[0053] In some alternative embodiments, the load component 25 includes: a first motor and a second motor; the first motor is used to drive the fan blades to rotate, and the second motor is used to drive the fan head 13 to rotate back and forth in a first dimension; the second control component 23 is used to control the operation of the first motor according to the first operation information; and / or to control the operation of the second motor according to the first operation information.

[0054] In this embodiment, the load component 25 disposed on the fan head 13 may include a first motor and a second motor. The first motor serves as the main motor of the fan and can be used to drive the fan blades to rotate. The second motor serves as a swing motor of the fan and can be used to drive the fan head 13 to rotate back and forth in a first dimension. The first dimension may be the vertical dimension when the fan base 11 is placed on a flat surface (e.g., a desktop), that is, the second motor can be used to drive the fan head 13 to swing up and down repeatedly in the vertical dimension. The second control component 23 can control the operation of the first motor and / or the second motor in the load component 25 according to the received first operation information, thereby realizing the fan blade rotation and / or up and down swing function.

[0055] For example, when the first operation information only includes the instruction to start the fan, the second control component 23 can control the first motor in the load component 25 to operate according to the first operation information, so that the first motor drives the fan blades to rotate, thereby realizing the fan start; when the first operation information includes both the instruction to start the fan and the instruction to start the fan to swing up and down, the second control component 23 can control the first motor and the second motor in the load component 25 to operate according to the first operation information, so that the first motor drives the fan blades to rotate, and the second motor drives the fan head 13 to rotate vertically and repeatedly, thereby realizing the fan start and the fan head swinging up and down repeatedly.

[0056] In other alternative embodiments, in addition to the first motor and the second motor, the load component 25 may also include load components capable of performing other functions, such as a plasma generator for generating plasma ions to purify the air.

[0057] In some alternative embodiments, the signal receiving module 24 is attached to the second motor, and whether the second motor is running or not, the signal transmission range of the signal transmitting module 22 corresponds to the signal receiving range of the signal receiving module 24.

[0058] In this embodiment, the second motor can be fixedly installed at the axial center position in the fan head 13, and its position is relatively fixed relative to that of the metal bracket 12. In order to ensure that the signal transmission range of the signal transmitting module 22 corresponds to the signal receiving range of the signal receiving module 24, the signal receiving module 24 can be installed at the axial center position at the bottom of the fan head. Therefore, the signal receiving module 24 can be installed near the second motor, that is, attached to the second motor, so that when the fan head 13 rotates, the signal transmission range of the signal transmitting module 22 can always be maintained to correspond to the signal receiving range of the signal receiving module 24, thereby maintaining the stable transmission of infrared signals.

[0059] In some optional embodiments, the second control component 23 includes a second control module, a first motor drive module for driving the first motor, and a second motor drive module for driving the second motor; the second control module 23 is configured to send first drive information to the first motor drive module according to the first operation information, so that the first motor drive module drives the first motor to operate; and / or, send second drive information to the second motor drive module according to the first operation information, so that the second motor drive module drives the second motor to operate.

[0060] In this embodiment, the second control component 23 located at the fan head 13 serves as a slave control component, specifically including a second control module, a first motor drive module, and a second motor drive module. The second control module acts as the execution entity that receives first operation information and controls the load component according to the first operation information; the first motor drive module drives the first motor to operate according to the control instructions or drive information from the second control module; and the second motor drive module drives the second motor to operate according to the control instructions or drive information from the second control module.

[0061] For example, the second control module may be a central processing unit (CPU), a digital signal processor (DSP), a microcontroller unit (MCU), or a field-programmable gate array (FPGA), etc.

[0062] As an example, Figure 3 This is a schematic diagram of the composition structure of the second control component according to an embodiment of the present invention; as shown... Figure 3 As shown, the second control component 23 includes a second control module 31, a first motor drive module 32, and a second motor drive module 33, combined with... Figure 2The second control module 31 in the second control component 23 is electrically connected to the signal receiving module 24. After receiving the first operation information through the signal receiving module 24, the second control module 31 can generate corresponding control commands or drive information according to the first operation information. For example, it can send the first control command or the first drive information to the first motor drive module 32 to control the first motor in the load component 25 to rotate, thereby realizing the rotation of the fan blades. It can also send the second control command or the second drive information to the second motor drive module 33 according to the first operation information to control the second motor in the load component 25 to rotate, thereby realizing the vertical rotation of the fan head.

[0063] In other alternative embodiments, the second control component 25 may further include a generator drive module, and the second control module 31 is further configured to send fourth drive information to the generator drive module according to the first operation information, so as to control the generator drive module to drive the ion generator in the load component 25 to operate and generate ions.

[0064] It should be noted that after the second control module 31 receives the electrical signal carrying the first operation information through the signal receiving module 24, it needs to parse the electrical signal to obtain the first operation information including one or more function instructions. The embodiments of the present invention do not impose specific restrictions on the method of parsing the electrical signal.

[0065] In some alternative embodiments, the fan base 11 is mounted on a chassis, and a third motor is also provided inside the fan base 11. The third motor is used to drive the fan base 11 to rotate back and forth in a second dimension.

[0066] In this embodiment, a third motor can also be provided inside the fan base 11. The third motor, as another swing motor of the fan, can be used to drive the connecting rod to make the fan base 11 rotate back and forth in the second dimension. The second dimension can be the horizontal dimension when the fan base 11 is placed parallel to the plane (such as a desktop). That is, the third motor can be used to drive the fan base 11 to swing left and right repeatedly in the horizontal dimension.

[0067] It is understood that the fan base 11 can be mounted on the chassis. When the third motor drives the fan base 11 to swing left and right repeatedly in the horizontal dimension, the chassis remains fixed, and only the fan base 11 swings left and right repeatedly under the drive of the third motor.

[0068] In some alternative embodiments, the first control component 21 is further configured to acquire second operation information from the user and control the operation of the third motor based on the second operation information.

[0069] In this embodiment, the first control component 21 can also acquire the user's second operation information and control the operation of the third motor inside the fan base 11 according to the second operation information.

[0070] It is understood that the second operational information may be operational information related to the fan base 11, which may be collected directly through the UI panel located on the front of the fan base 11. For example, the second operational information may include left and right oscillation mode and frequency, etc.

[0071] For example, when the second operation information is an instruction to start the fan to swing left and right, the second control component 23 can control the third motor to operate according to the second operation information, thereby driving the fan base 11 to rotate repeatedly in the horizontal direction, so as to realize the fan head swinging left and right repeatedly.

[0072] In some optional embodiments, the first control component 21 includes a first control module and a third motor drive module; the first control module is used to send third drive information to the third motor drive module according to the second operation information, so that the third motor drive module drives the third motor to operate.

[0073] In this embodiment, the first control component 21 located inside the fan base 11 serves as the main control component, specifically including a first control module and a third motor drive module. The first control module acts as the execution entity that receives first operation information and / or second operation information and controls the third motor drive module according to the second operation information; the third motor drive module drives the third motor to operate according to the control instructions or drive information from the first control module. For example, the first control module may be a CPU, DSP, MCU, or FPGA, etc.

[0074] As an example, Figure 4 This is a schematic diagram of the composition structure of the first control component according to an embodiment of the present invention; as shown... Figure 4 As shown, the first control component 21 includes a first control module 41, a third motor drive module 42, and a UI panel 43, combined with... Figure 2 The first control module 41 in the first control component 21 is electrically connected to the signal transmission module 22. The first control module 41 can send third drive information to the third motor drive module 42 according to the received second operation information, so as to control the third motor drive module 42 to drive the third motor in the fan base 11 to operate, so as to realize the linkage drives the fan base 11 to rotate horizontally.

[0075] In some alternative embodiments, the metal bracket 12 includes a first metal bracket and a second metal bracket, wherein the first metal bracket is used to provide a power signal to the second control component 23 and the load component 25; and the second metal bracket is used to provide a ground signal to the second control component 23 and the load component 25.

[0076] In this embodiment, the metal bracket 12 for connecting the fan head 13 and the fan base 11 may include a first metal bracket and a second metal bracket. The first metal bracket is used to provide a power signal to the second control component 23 and the load component 25 disposed on the fan head 13, and the second metal bracket is used to provide a ground signal to the second control component 23 and the load component 25, thereby maintaining the circuit path when the fan is powered on.

[0077] As an example, Figure 2 As shown, facing the front of the fan, the metal bracket on the right can be a first metal bracket, used to provide a power signal to the second control component 23 and the load component 25. For example, the power signal can be referred to as the supply voltage (VCC, Voltage Current Condenser) signal. The metal bracket on the left can be a second metal bracket, used to provide a ground signal to the second control component 23 and the load component 25. For example, one end of the second metal bracket can be connected to a ground wire or a zero line (GND, Ground) terminal, that is, the second control component 23 and the load component 25 are connected to the ground potential through the second metal bracket to provide a ground signal. It can be understood that by using the first metal bracket as the VCC terminal and the second metal bracket as the GND terminal, power is supplied to the second control component 23 and the load component 25.

[0078] In this embodiment, two metal brackets are used as power supply lines, dividing the load end and main control end of the fan into two independent parts, upper and lower. By using the wireless connection between the fan head 13 and the fan base 11, the number of ribbon cables caused by communication and power supply between the upper and lower parts is reduced, thereby reducing the overall thickness of the brackets and the width of the slot in the rear fan cover. The width of the rear fan cover that needs to be cleared is the thickness of the bracket, so that the user's fingers cannot be inserted into the slot. This ensures that the user cannot touch the bracket during the fan's oscillation, avoiding pinching injuries, enhancing safety performance, and improving the fan's practicality and versatility.

[0079] Based on the fan described in the above embodiments, this invention also provides a fan control method. Figure 5 This is a flowchart illustrating the fan control method according to an embodiment of the present invention; as shown. Figure 5 As shown, the method includes:

[0080] Step 201: The first control component located inside the fan base acquires the user's first operation information;

[0081] Step 202: Send the first operation information through the signal transmission module;

[0082] Step 203: The second control component located inside the fan head receives the first operation information through the signal receiving module;

[0083] Step 204: Based on the first operation information, control the load components inside the fan head to start or stop operating.

[0084] In this embodiment, when the fan is running, the first control component located on the fan base acquires the user's first operation information and sends it to the second control component on the fan head via a signal transmitting module connected to the first control component in the fan base. The first operation information may be user-set control information (i.e., UI information) collected by the first control component through the UI panel located on the fan base. This control information may include user-set fan speed level, oscillation mode and frequency, timing, and other information.

[0085] In some optional embodiments, after step 201, the method further includes: the first control component determining whether the first operation information is updated operation information;

[0086] Accordingly, sending the first operation information through the signal transmission module includes: when the first control component determines that the first operation information is updated operation information, sending the first operation information through the signal transmission module.

[0087] In this embodiment, after obtaining the first operation information, the first control component needs to determine whether the first operation information is updated operation information, so as to determine whether the first operation information needs to be sent.

[0088] Specifically, the first control component can compare the first operation information acquired in the current round with the first operation information acquired in the previous round. If they are completely consistent, it means that the first operation information in the current round has not been updated. In this case, the first control component only needs to send the original control signal carrying the first operation information of the previous round to the second control component, without having to send the first operation information to the second control component. If the first operation information acquired in the current round is different from the first operation information acquired in the previous round, it means that the first operation information in the current round has been updated. In this case, the first control component needs to send the first operation information of the current round to the second control component through the signal transmission module.

[0089] In this embodiment, after the first control component obtains the user's first operation information, it needs to send the first operation information to the second control component located at the fan head through the signal transmission module located at the fan base, so as to control the fan head to realize the relevant functions of the fan head through the first operation information.

[0090] In some optional embodiments, taking the infrared transmission method as an example, the first control module in the first control component located on the fan base sends the first operation information to the signal transmitting module in the form of an electrical signal. The signal transmitting module needs to convert the electrical signal carrying the first operation information into an infrared signal and send the converted infrared signal carrying the first operation information to the signal receiving module located on the fan head. After receiving the infrared signal carrying the first operation information, the signal receiving module converts the infrared signal into an electrical signal and then transmits the electrical signal carrying the first operation information to the second control component.

[0091] In this embodiment, after the first control component sends the first operation information, the second control component located at the fan head receives the first operation information through the signal receiving module, and controls the start or stop of the load component set at the fan head according to the first operation information, so as to realize the corresponding function of the fan head based on the first operation information.

[0092] In some optional embodiments, after step 203, the method further includes: the second control component determining whether the first operation information is updated operation information;

[0093] Accordingly, controlling the load component inside the fan head to run or stop running according to the first operation information includes: when the second control component determines that the first operation information is updated operation information, controlling the load component to run or stop running according to the first operation information.

[0094] In this embodiment, after receiving the first operation information through the signal receiving module, the second control component needs to determine whether the first operation information is updated operation information, so as to determine whether the first operation information needs to be sent to the load component.

[0095] Specifically, the second control component needs to compare the first operation information received through the signal receiving module with the first operation information received in the previous round. If they are completely consistent, it means that the first operation information in the current round has not been updated. In this case, the second control component only needs to continue sending the first operation information of the previous round to the load component, without having to send the first operation information to the load component. If the first operation information received in the current round is different from the first operation information received in the previous round, it means that the first operation information in the current round has been updated, and the second control component needs to send the first operation information of the current round to the load component.

[0096] It should be noted that after the second control module receives the electrical signal carrying the first operation information through the signal receiving module, it needs to parse the electrical signal to obtain the first operation information including one or more function instructions. The embodiments of the present invention do not impose specific restrictions on the method of parsing the electrical signal.

[0097] In this embodiment, the second control component can control the operation of the first motor and / or the second motor in the load component according to the received first operation information.

[0098] Specifically, the second control module in the second control component can send first drive information to the first motor drive module in the second control component according to the received first operation information, so as to control the first motor drive module to drive the first motor in the load component to rotate, thereby driving the fan blades to rotate; it can also send second drive information to the second motor drive module in the second control component according to the first operation information, so as to control the second motor drive module to drive the second motor in the load component to rotate, thereby driving the fan head to rotate repeatedly in the first dimension. The first dimension can be the vertical dimension when the fan base is placed on a plane (such as a desktop), that is, driving the fan head to swing up and down repeatedly in the vertical dimension.

[0099] The second control module serves as the execution entity that receives the first operation information and controls the load component according to the first operation information; the first motor drive module is used to drive the first motor to operate according to the control instructions or drive information of the second control module; and the second motor drive module is used to drive the second motor to operate according to the control instructions or drive information of the second control module.

[0100] In other alternative embodiments, the second control component may further include a generator drive module, and the load component may further include a load component capable of performing other functions, such as a plasma ion generator. The second control module may also send fourth drive information to the generator drive module according to the first operation information to control the generator drive module to drive the plasma ion generator to operate, generate plasma ions, and realize the air purification function.

[0101] In some alternative embodiments, the first control component may also acquire second operation information from the user and control the operation of a third motor inside the fan base based on the second operation information.

[0102] Specifically, after obtaining the second operation information, the first control module in the first control component can send the third drive information to the third motor drive module in the first control component according to the second operation information, so as to control the third motor drive module to drive the third motor located on the fan base to operate, thereby driving the connecting rod to make the fan base rotate back and forth in the second dimension. The second dimension can be the horizontal dimension when the fan base is placed on a plane (such as a desktop), that is, to drive the fan base to swing left and right repeatedly in the horizontal direction.

[0103] The second operation information can be operation information related to the fan base, which can be collected directly through the UI panel on the front of the fan base. For example, the second operation information may include left-right oscillation mode and frequency, etc. The fan base can be mounted on a chassis. When the third motor drives the fan base to oscillate left and right repeatedly in the horizontal dimension, the chassis remains stationary, and only the fan base oscillates left and right under the drive of the third motor. The first control module acts as the execution body for receiving the first operation information and / or the second operation information, and controlling the third motor drive module according to the second operation information. The third motor drive module is used to drive the third motor to operate according to the control instructions or drive information of the first control module.

[0104] The following example illustrates the fan control method. Figure 6 This is a flowchart illustrating a fan control method in an application example of an embodiment of the present invention; as shown below. Figure 6 As shown, combined with Figure 3 and Figure 4 The schematic diagram of the physical structure shown illustrates the specific process of controlling the operation of the fan head as follows:

[0105] Step 301: The first control module in the first control component obtains the user's operation information.

[0106] Step 302: The first control module determines whether the current operation information has been updated based on the operation information obtained in the previous round. If it determines that the current operation information has not been updated, it will not execute the subsequent steps and will directly obtain the operation information for the next round.

[0107] Step 303: If the first control module determines that the operation information has been updated, it sends the operation information to the signal receiving module at the fan head through the signal transmitting module.

[0108] In this example, the operation information can be equivalent to the first operation information in the above embodiments, that is, the first operation information is the corresponding operation information for the function of the fan head. In other optional examples, when the operation information is recognized by the first control module as the corresponding operation information for the load component in the fan base (that is, equivalent to the second operation information in the above embodiments), the first control module can directly control the load component (e.g., the third motor in the above embodiments) in the fan base to run or stop running based on the operation information.

[0109] Step 304: After receiving the operation information, the signal module transmits the operation information to the second control module in the second control component.

[0110] Step 305: The second control module determines whether the currently received operation information has been updated based on the operation information received in the previous round. If it determines that the current operation information has not been updated, it will not execute the subsequent steps.

[0111] Step 306: If the second control module determines that the current operation information has been updated, it sends first drive information to the first motor drive module in the load component according to the operation information to control the corresponding first motor to rotate, and / or sends second drive information to the second motor drive module according to the first operation information to control the corresponding second motor to rotate, thereby controlling the operation of the load component.

[0112] It should be noted that this invention proposes a fan control method. The first control component of the fan obtains the user's first operation information and sends the first operation information to the second control component through a signal transmitting module. The second control component of the fan receives the first operation information through a signal receiving module and controls the load component inside the fan head to run or stop running according to the first operation information. The signal transmitting module and the signal receiving module are used to realize the wireless connection between the fan head and the fan base, so as to reduce the overall thickness of the bracket, thereby reducing the width of the slot in the rear mesh cover, reducing the risk of accidental injury caused by the user's fingers sticking into the slot, and enhancing safety performance.
