[0002] Circulation fans are a new generation of fans that are designed by improving the air duct of traditional electric fans. They are popular among users because of their smaller size, multi-angle shaking, longer air supply distance, and quieter operation.

[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] The control method of the fan provided in the embodiment of the present application can be applied to the fan as shown in Figure 1. The fan includes a controller 102, a fan assembly 103, a heating assembly 104 and a detection assembly 105. The fan assembly 103 includes an air inlet and an air outlet, an air duct is formed between the air inlet and the air outlet, and the heating assembly 104 is arranged in the air duct of the fan assembly 103. The fan assembly 103, the heating assembly 104 and the detection assembly 105 are all connected to the controller 102, and the detection assembly 105 is used to detect the angle parameters of the heating assembly 104 and the fan assembly 103 and send them to the controller 102.

[0055] Specifically, the fan assembly 103 is the part of the fan responsible for generating airflow, and mainly includes a fan drive module, a fan blade assembly and an air duct. The air inlet is the entrance for the air flow to enter the fan, and the air outlet is the outlet of the air duct where the air flow is blown out. The air duct formed between the air inlet and the air outlet provides a circulation path for the air flow.

[0056] When the fan is started, the controller 102 drives the fan blades to rotate through the fan driving module, thereby generating airflow, which can be directed to a specific direction or area through the air duct to achieve ventilation, heat dissipation or other purposes.

[0057] The heating component 104 can generate heat and is arranged in the air duct of the fan component 103, so that when the fan is working, the generated airflow will pass through the heating component 104 and be heated to take away the heat generated by the heating component 104. Therefore, the addition of the heating component 104 enables the fan system to not only have a heat dissipation function, but also provide a heating function in certain application scenarios, such as winter heating, equipment preheating, etc.

[0058] Specifically, the heating component 104 may include a heating element and a heating drive module connected to the controller 102. The heating element may be a PTC (Positive Temperature Coefficient) heating element, a semiconductor heating element, or a heating wire, etc. When the controller 102 controls the operation of the heating component 104, it may include controlling the heating element to heat or not heat, and also includes controlling the heating drive module to drive the heating element to move, so as to adjust the position of the heating element.

[0059] The detection component 105 is used to detect the angle parameters of the heating component 104 and the fan component 103 and output them to the controller 102. The structure of the detection component 105 can be set according to actual conditions. In one embodiment, the detection component 105 includes a first detection unit arranged on the heating component 104, and the first detection unit is connected to the controller 102. The first detection unit is used to detect and transmit the first angle parameter of the heating component 104 to the controller 102.

[0060] The first detection unit may include a tilt angle sensor disposed on the heating element of the heating component 104, which is connected to the controller 102 and is used to detect and transmit a tilt angle parameter of the heating element relative to the plane where the fan is located (eg, the ground), and the tilt angle parameter may be used as a first angle parameter.

[0061] The second angle parameter can characterize the angle between the air outlet of the fan assembly and the plane where the fan is located (such as the ground), or the angle between the airflow path of the air duct and the plane where the fan is located (such as the ground). In some embodiments, the fan can only shake its head left and right, so the angle between the air outlet of the fan assembly 103 and the plane where the fan is located is the initial angle and remains unchanged. Exemplarily, when the angle between the air outlet of the fan assembly 103 and the plane where the fan is located is the initial angle, the air outlet is perpendicular to the ground. In this embodiment, the initial angle can be used as the second angle parameter, or the angle between the airflow path of the air duct and the plane where the fan is located is obtained according to the initial angle as the second angle parameter.

[0062] In other embodiments, the fan has functions such as shaking head up and down, left and right, 270 degrees or 360 degrees. In actual implementation, the controller 102 controls the rotation of the driving gear through the fan driving module to drive the fan assembly 103 to move through the driving gear, thereby realizing the shaking head function. In these embodiments, the detection assembly 105 also includes a second detection unit disposed on the fan assembly 102, and the second detection unit is connected to the controller 102.

[0063] In some embodiments, the second detection unit includes an angle detection sensor disposed in the fan assembly 103, the angle detection sensor is connected to the controller 102, and the angle detection sensor is used to detect the rotation angle of the driving gear of the fan assembly 103 and transmit the rotation angle to the controller 102. The controller 102 obtains the second angle parameter according to the rotation angle.

[0064] Furthermore, the controller 102 receives operation control instructions; the operation control instructions include cool air mode instructions and warm air mode instructions; the first angle parameter of the heating component is obtained through the first detection unit in the detection component 105, and the second angle parameter of the fan component is obtained; the operation of the heating component is controlled according to the first angle parameter, the second angle parameter and the operation control instructions, so that the relative position state between the heating component and the fan component matches the operation control instructions.

[0065] In an exemplary embodiment, as shown in FIG2 , a fan control method is provided, which is described by taking the method applied to the controller 102 in FIG1 as an example, and includes the following steps 202 to 206 . Among them:

[0066] Step 202: Receive an operation control instruction.

[0067] The operation control instruction may be sent to the controller by the user through an input device such as a control panel, a remote controller, or a terminal device (such as a mobile phone, a tablet computer, a wearable device, etc.) of the fan. The operation control instruction may be input when the fan is powered on for the first time, or may be input before the current power-on, such as input and saved when the user last used the fan.

[0068] The operation control instruction includes a cool air mode instruction and a warm air mode instruction. In the cool air mode, the user expects the fan to only blow air (without heating). In the warm air mode, the user expects the fan to heat and blow air, and the air blown out at this time is warm air. It can be understood that the operation control instruction may also include information such as the target blowing time of the cool air mode or the warm air mode, the target blowing temperature of the warm air mode, etc.

[0069] Step 204, obtaining a first angle parameter of the heating component and a second angle parameter of the fan component.

[0070] Among them, the first angle parameter represents the inclination angle parameter of the heating element in the heating component relative to the plane where the fan is located (such as the ground). The second angle parameter can represent the angle between the air outlet of the fan component and the plane where the fan is located (such as the ground), or the angle between the airflow path of the air duct and the plane where the fan is located (such as the ground). In this embodiment, the second angle parameter is used to represent the angle between the air outlet of the fan component and the plane where the fan is located (such as the ground).

[0071] Step 206: Control the heating component according to the first angle parameter, the second angle parameter and the operation control instruction, so that the relative position state between the heating component and the fan component matches the operation control instruction.

[0072] Specifically, the reference angle between the airflow path of the air duct and the plane where the fan is located can be first determined according to the second angle parameter. It can be understood that when the structure of the fan assembly is determined, the angle between the airflow path of the air duct and the air outlet is determined, usually in a vertical relationship. Therefore, the reference angle between the airflow path and the plane where the fan is located can be calculated according to the second angle parameter.

[0073] Then, based on the first angle parameter of the heating element's inclination and the reference angle, the angle difference required to move the heating element to the target position is calculated, and then the motor in the heating drive module controls the heating component to move according to the calculated angle difference, and the heating element reaches the target position after movement.

[0074] Among them, the target position needs to be determined in combination with the operation control instruction. In one embodiment, if the power-on instruction is a cool air mode instruction, as shown in Figure 3 (the dotted line indicates the airflow direction), the target position can be a position where the extension direction of the heating element in the heating component is parallel to the airflow path of the fan component. Correspondingly, step 206 may include: based on the first angle parameter and the second angle parameter, controlling the heating component to move to a position where its extension direction is parallel to the airflow path of the fan component.

[0075] In actual implementation, the heating element may be a long strip structure, with its length direction being the extension direction, which is conducive to heat dissipation. By making the extension direction of the heating element parallel to the airflow path of the fan assembly, the influence of the heating element on the airflow can be minimized, ensuring that the airflow of the fan can pass through the heating element smoothly without obstruction, thereby improving the air output efficiency. It is understandable that during this process, the heating element may remain in a closed state without generating heat.

[0076] If the power-on instruction is a warm air mode instruction, as shown in Figure 4, the target position may be a position where the extension direction of the heating element in the heating component is perpendicular to the airflow path. Step 206 may include: based on the first angle parameter and the second angle parameter, controlling the heating component to move to a position where the extension direction is perpendicular to the airflow path of the fan component, and controlling the heating component to turn on.

[0077] By moving the heating element in the heating component to a position perpendicular to the airflow path in its extension direction, the heating element can cover the air inlet and outlet paths to the maximum extent, so that the airflow is quickly and evenly heated when passing through the heating component, thereby improving the hot air outlet effect. In this process, the controller controls the heating component to turn on, and the controller can also determine the heating power of the heating component according to the target blowing temperature, and control the heating element to operate based on the heating power to provide gas at the temperature required by the user.

[0078] In this embodiment, the precise first angle parameter of the heating component and the second angle parameter of the fan component are first determined, and then the position of the heating component is controlled to be adjusted based on these angle parameters, which can ensure that the adjusted position is more precise, so that in different modes, the effect of the heating element on the airflow can meet expectations, thereby improving the efficiency of the cool or warm air output.

[0079] The control method of the above-mentioned fan can adjust the position of the heating component according to the type of operation control instruction, so that the position state between the heating component and the fan component can match the warm air mode instruction and the cool air mode instruction respectively. When the fan component emits cool air, the blocking of the air duct by the position-adjusted heating component can be reduced, thereby improving the cool air output efficiency. When the fan component emits warm air, the blocking of the air duct by the position-adjusted heating component can be strengthened to increase the outlet air temperature. Therefore, by adjusting the position of the heating component in a targeted manner according to the actual operation control instruction, it is ensured that the fan component can achieve the best air output effect in different operation modes.

[0080] In an exemplary embodiment, as shown in FIG. 5 , before step 206 , the fan control method further includes step 302 : judging whether the fan assembly is in an initial return state based on the second angle parameter.

[0081] If not, then execute step 304: based on the second angle parameter, control the fan assembly to return to the initial return state. If yes, then execute step 206.

[0082] It can be understood that after step 304, the controller can directly execute step 206, or return to execute step 302, which can be set according to actual needs.

[0083] In the initial return state, the airflow path of the fan assembly is parallel to the plane where the fan is located (such as the ground). In this embodiment, it is first determined whether the airflow path of the fan assembly is parallel to the ground. If it is not parallel to the ground, the angle difference required to move the fan assembly parallel to the ground is calculated based on the second angle parameter, and then the motor in the fan drive module controls the fan assembly to move according to the angle difference. After the movement, the airflow path of the fan assembly is parallel to the ground. The airflow path parallel to the ground can have lower resistance and higher flow, which is more in line with user expectations and the fan's air outlet effect is more reliable.

[0084] In this embodiment, by judging whether the fan assembly is in the initial return state based on the second angle parameter, and controlling its return when it is not returned, it can be ensured that the fan assembly is in a known and stable state each time the machine is turned on and operated, thereby improving the accuracy and reliability of subsequent control operations. At the same time, it also provides users with a more consistent and predictable use experience.

[0085] In an exemplary embodiment, as shown in FIG. 6 , after step 206 , the fan control method further includes steps 402 and 404 .

[0086] Step 402, determining the swing path of the fan assembly.

[0087] The shaking path of the shaking component can be determined based on the target shaking direction and the target shaking angle range. The target shaking direction and the target shaking angle range can be determined according to the shaking instruction, which can be a separate instruction issued by the user or issued by the user through a running control instruction.

[0088] Step 404: Control the heating component and the fan component to rotate synchronously according to the shaking path.

[0089] During the synchronous rotation, the relative position between the heating component and the fan component remains unchanged. If the current mode is cool air, the heating element in the heating component is parallel to the airflow path of the shaking component while the fan component is shaking based on the shaking path. If the current mode is warm air, the heating element in the heating component is perpendicular to the airflow path of the shaking component while the fan component is shaking based on the shaking path.

[0090] There is no unique way to control the synchronous rotation of the heating component and the fan component according to the shaking path. In some implementations, the controller determines the movement path of the heating component according to the shaking path of the fan component, and then controls the motor in the fan drive module and the heating drive module motor according to the shaking path, so that the relative position between the heating component and the shaking component remains unchanged. In other embodiments, the mechanical structure of the heating component and the shaking component can achieve synchronous operation so that the relative position of the two remains unchanged.

[0091] In this embodiment, during the rotation of the fan assembly, the relative position state between the heat generating assembly and the fan assembly is kept unchanged, thereby ensuring the consistency and stability of the air outlet effect.

[0092] In one embodiment, as shown in Figure 7, after step 206, the fan control method also includes step 502: when it is determined that the position of the fan component is abnormally changed according to the second angle parameter, the heating component is controlled according to the first angle parameter, the second angle parameter and the operation control instruction so that the position state between the heating component and the fan component matches the operation control instruction.

[0093] In actual implementation, after the fan assembly and the heating assembly start running, the controller will continue to obtain the first angle parameter of the heating assembly and the second angle parameter of the fan assembly, and compare the second angle parameter obtained in real time with the shaking path of the fan assembly. If it is found that the current second angle parameter does not match the shaking path, it is determined that the position of the fan assembly has been abnormally changed, for example, the position of the fan assembly has been artificially changed by a person, as shown in Figure 8.

[0094] When the controller detects that the fan assembly is abnormally positioned, it will immediately take measures to restore the normal position relationship. Specifically, the controller recalculates and adjusts the position of the heating assembly according to the current first angle parameter and the second angle parameter, and the position state between the heating assembly and the fan assembly after adjustment matches the operation control instruction, that is, ensuring that the heating element can correctly cover or be perpendicular to the airflow path.

[0095] In this embodiment, during the operation of the fan, abnormal position of the fan component is continuously monitored to ensure that the positional relationship between the heat generating component and the fan component always meets the expected requirements, thereby improving the reliability of the fan.

[0096] In actual implementation, the fan control method may further include: receiving a shutdown instruction, and controlling the fan component to return to a normal state.

[0097] The shutdown command can be sent to the controller by the user through the fan's control panel, remote control, or input device such as a terminal device. After receiving the shutdown command, the controller will control the fan assembly to stop blowing air and the heating element to stop heating. At the same time, the controller will also control the fan assembly to return to the normal state, which helps to keep the device clean, reduce energy consumption, and prepare for the next use.

[0098] In order to better understand the above embodiment, a detailed explanation is provided below in conjunction with a specific embodiment. In one embodiment, after receiving the operation control instruction, the controller first obtains the first angle parameter of the heating component and the second angle parameter of the fan component; based on the second angle parameter, it is determined whether the fan component is in the initial return state, and if the fan component is not returned, its position is adjusted to return it. When the fan component is in the return state, the airflow path of the fan component is parallel to the ground.

[0099] At the same time, the controller will also adjust the position of the heating element in the heating component according to the first angle parameter, the second angle parameter and the operation control instruction. If the power-on instruction is a cool air mode instruction, the heating component is adjusted to move parallel to the airflow path of the fan component based on the first angle parameter and the second angle parameter; if the power-on instruction is a warm air mode instruction, the heating component is controlled to move perpendicular to the airflow path of the fan component based on the first angle parameter and the second angle parameter, and the heating element is controlled to start heating.

[0100] Furthermore, the controller will also determine whether the shaking head function is turned on. When the shaking head function is turned on, it will first determine the shaking head path of the fan assembly; then, the heating assembly and the fan assembly will be controlled to rotate synchronously according to the shaking head path. During the synchronous rotation process, the relatively vertical position state or the relatively parallel position between the heating assembly and the fan assembly remains unchanged.

[0101] When the fan assembly shakes its head, the controller will also obtain the first angle parameter and the second angle parameter in real time to determine whether the fan assembly has been artificially changed according to the second angle parameter. Once it is found that the fan assembly has been artificially changed, the position of the heating assembly is adjusted according to the first angle parameter and the second angle parameter so that the heating assembly and the fan assembly continue to remain relatively vertical or relatively parallel.

[0102] The above-mentioned fan control method can reduce the obstruction of the heating element to the air inlet when the heating element is not heated, and allow the shaking function to be turned on. The heating element component rotates synchronously and always remains perpendicular to the air outlet, so that the whole machine has a larger air intake in the same power and the same scene in the cool wind mode, and the effect of blowing and cooling is better. After the heating element is turned on, in order to provide hot air to the user more directly, the heating element is parallel to the air outlet, so that the heating element covers the entire air inlet to the greatest extent, making the temperature of the blown air higher and the heating effect better. In this way, the fan's air outlet effect is maximized and it is more energy-saving.

[0103] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0104] Based on the same inventive concept, the embodiment of the present application also provides a fan control device for implementing the fan control method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in the embodiments of the control device for one or more fans provided below can refer to the limitations of the fan control method above, and will not be repeated here.

[0105] In an exemplary embodiment, as shown in FIG9 , a fan control device is provided, wherein the fan comprises a fan assembly and a heating assembly, wherein the heating assembly is arranged in an air duct of the fan assembly. The fan control device comprises: an instruction acquisition module 902, an angle acquisition module 904 and an operation control module 906, wherein:

[0106] The instruction acquisition module 902 is used to receive the operation control instruction; the operation control instruction includes a cool air instruction and a warm air instruction;

[0107] An angle acquisition module 904, used to acquire a first angle parameter of the heating component and a second angle parameter of the fan component;

[0108] The operation control module 906 is used to control the heating component according to the first angle parameter, the second angle parameter and the operation control instruction, so that the position state between the heating component and the fan component matches the operation control instruction.

[0109] In one embodiment, the operation control module 906 is also used to control the heating component to move to a direction in which its extension is parallel to the airflow path of the fan component based on the first angle parameter and the second angle parameter if the operation control instruction is a cool air mode instruction; if the operation control instruction is a warm air mode instruction, then based on the first angle parameter and the second angle parameter, control the heating component to move to a direction perpendicular to the airflow path of the fan component and control the heating component to turn on.

[0110] In one embodiment, the operation control module 906 is further used to determine whether the fan assembly is in an initial return state based on the second angle parameter; in the initial return state, the airflow path of the fan assembly is parallel to the plane where the fan is located;

[0111] The operation control module 906 is further used to control the fan assembly to return to an initial return state based on the second angle parameter.

[0112] In one embodiment, the operation control module 906 is also used to determine the swing path of the fan assembly; control the synchronous rotation of the heating assembly and the fan assembly according to the swing path; during the synchronous rotation process, the relative position state between the heating assembly and the fan assembly remains unchanged.

[0113] In one embodiment, the operation control module 906 is also used to control the heating component according to the first angle parameter, the second angle parameter and the operation control instruction when it is determined that the position of the fan component is abnormally changed according to the second angle parameter, so that the position state between the heating component and the fan component matches the operation control instruction.

[0114] Each module in the above-mentioned fan control device can be implemented in whole or in part by software, hardware or a combination thereof. Each of the above-mentioned modules can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute operations corresponding to each of the above modules.

[0115] In an exemplary embodiment, a fan is provided, and the fan may be a cooling and heating circulation fan. Referring to FIG. 1 , the fan includes a controller 102, a fan assembly 103, a heating assembly 104, and a detection assembly 105. The fan assembly 103 includes an air inlet and an air outlet, and an air duct is formed between the air inlet and the air outlet. The heating assembly 104 is disposed in the air duct of the fan assembly 103. The fan assembly 103, the heating assembly 104, and the detection assembly 105 are all connected to the controller 102, and the detection assembly 105 is used to detect the angle parameters of the heating assembly 104 and the fan assembly 103 and send them to the controller 102.

[0116] Specifically, the fan assembly 103 is the part of the fan responsible for generating airflow, and mainly includes a fan drive module, a fan blade assembly and an air duct. The air inlet is the entrance for the air flow to enter the fan, and the air outlet is the outlet of the air duct where the air flow is blown out. The air duct formed between the air inlet and the air outlet provides a circulation path for the air flow.

[0117] When the fan is started, the controller 102 drives the fan blades to rotate through the fan driving module, thereby generating airflow, which can be directed to a specific direction or area through the air duct to achieve ventilation, heat dissipation or other purposes.

[0118] The heating component 104 can generate heat and is arranged in the air duct of the fan component 103, so that when the fan is working, the generated airflow will pass through the heating component 104 and be heated to take away the heat generated by the heating component 104. Therefore, the addition of the heating component 104 enables the fan system to not only have a heat dissipation function, but also provide a heating function in certain application scenarios, such as winter heating, equipment preheating, etc.

[0119] Specifically, the heating component 104 may include a heating element and a heating drive module connected to the controller 102. The heating element may be a PTC (Positive Temperature Coefficient) heating element, a semiconductor heating element, or a heating wire, etc. When the controller 102 controls the operation of the heating component 104, it may include controlling the heating element to heat or not heat, and also includes controlling the heating drive module to drive the heating element to move, so as to adjust the position of the heating element.

[0120] The detection component 105 is used to detect the angle parameters of the heating component 104 and the fan component 103 and output them to the controller 102. The structure of the detection component 105 can be set according to actual conditions. In one embodiment, the detection component 105 includes a first detection unit arranged on the heating component 104, and the first detection unit is connected to the controller 102. The first detection unit is used to detect and transmit the first angle parameter of the heating component 104 to the controller 102.

[0121] The first detection unit may include a tilt angle sensor disposed on the heating element of the heating component 104, which is connected to the controller 102 and is used to detect and transmit a tilt angle parameter of the heating element relative to the plane where the fan is located (eg, the ground), and the tilt angle parameter may be used as a first angle parameter.

[0122] In one embodiment, as shown in FIG. 10 , the first detection unit includes an angle detection component 106 , a carrier 107 and a conductive moving body 108 .

[0123] The carrier 107 is used to be disposed on the heating component 104. In the carrier 107, a plurality of conductive positions 109 are disposed along a direction consistent with the extension direction of the heating component 104. Each conductive position 109 is connected to the controller 102 via the detection component 106. The conductive moving body 108 is movably disposed in the carrier 107.

[0124] The carrier 107 is used to support the conductive moving body 108. The carrier 107 is fixed to the heating element of the heating component. When the heating element is tilted, the conductive moving body 108 in the carrier 107 moves and contacts the corresponding conductive position 109. When the conductive moving body 108 contacts the corresponding conductive position 109, the angle detection component 106 transmits the corresponding first angle parameter to the controller 102.

[0125] The structure of the conductive moving body 108 can be set according to specific conditions. Optionally, the conductive moving body 108 is a conductive sphere. The carrier 107 can be a container capable of supporting the conductive sphere so that the conductive sphere moves within a desired range.

[0126] In actual implementation, when the heating element is parallel to the ground, the conductive sphere stays at an initial conductive position 109 due to gravity. When the heating element is tilted, the conductive sphere rolls along the carrier 107 under the action of gravity until it contacts the corresponding conductive position, as shown in Figures 11 and 12. At this time, the angle detection component 106 outputs corresponding parameters to the controller 102 according to the current conductive position 109, thereby obtaining the tilt angle parameters of the heating element relative to the ground.

[0127] In this embodiment, the first detection unit can monitor the tilt state of the heating element in the heating component in real time and accurately, and provide the controller 102 with an accurate first angle parameter to provide reliable data support for subsequent control.

[0128] The structure of the angle detection component 106 can be set according to specific circumstances. In one embodiment, referring to FIG. 10 again, the angle detection component 106 includes a grounding resistor R0 and a plurality of detection resistors R1, the number of the detection resistors R1 is the same as the number of the conductive positions 109, each conductive position 109 is connected to a first end of a detection resistor R1, the second end of each detection resistor R1 is connected to the first end of the grounding resistor R0, the first end of the grounding resistor R0 is connected to the controller 102, and the second end of the grounding resistor R0 is grounded.

[0129] In this embodiment, the conductive moving body 108 is connected to the power supply through a conductive spring, and the resistance values ​​of the detection resistors R1 are different. When the heating component (the heating body in it) is parallel to the ground, the conductive sphere contacts the initial conductive position 109, and the initial conductive position 109 is connected to the grounding resistor R0 through the detection resistor R1. The controller 102 can determine that the conductive sphere is currently contacting the initial conductive position by monitoring the received voltage parameters.

[0130] When the heating component is tilted, the conductive sphere rolls and contacts a conductive position 109, the conductive position 109 is connected to the grounding resistor R0 through the corresponding detection resistor R1. The controller 102 can determine which conductive position 109 the conductive sphere is currently contacting by monitoring the voltage change, and then calculate the tilt angle of the heating component and perform corresponding control operations accordingly.

[0131] The second angle parameter can characterize the angle between the air outlet of the fan assembly and the plane where the fan is located (such as the ground), or the angle between the airflow path of the air duct and the plane where the fan is located (such as the ground). In some embodiments, the fan can only shake its head left and right, so the angle between the air outlet of the fan assembly 103 and the plane where the fan is located is the initial angle and remains unchanged. Exemplarily, when the angle between the air outlet of the fan assembly 103 and the plane where the fan is located is the initial angle, the air outlet is perpendicular to the ground. In this embodiment, the initial angle can be used as the second angle parameter.

[0132] In other embodiments, the fan has functions such as shaking head up and down, left and right, 270 degrees or 360 degrees. Specifically, the controller 102 controls the rotation of the driving gear through the fan driving module to drive the fan assembly 103 to move through the driving gear, thereby realizing the shaking head function. In these embodiments, the detection assembly 105 also includes a second detection unit disposed on the fan assembly 102, and the second detection unit is connected to the controller 102.

[0133] In some embodiments, the detection component 105 further includes a second detection unit disposed in the fan component 103, and the second detection unit is connected to the controller 102. Specifically, the second detection unit may include an angle detection sensor connected to the controller 102, and the angle detection sensor is disposed in the fan component 103, and is used to detect the rotation angle of the driving gear in the fan component 103, and transmit the rotation angle to the controller 102; the controller 102 is used to determine the second angle parameter according to the rotation angle. Thus, the accuracy of the second angle parameter can be guaranteed, so that the position adjustment accuracy of the heating component (heating element) is higher.

[0134] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. In one embodiment,

[0135] The fan is powered on and the whole machine starts to work. At this time, the controller 102 detects the angle of the components on the heating element to ensure that the air outlet is perpendicular to the ground and the head of the machine has returned to the center state.

[0136] At this time, the heating element assembly 104 is parallel to the ground, and the conductive sphere in the first detection unit is not affected by any tension and does not change its position. At this time, the output parameter value received by the controller 102 is Ux1 (the value can be set according to different circuit requirements, and the overall calculation formula is Uxn=VCC*(R0R0+R1), where VCC represents the power supply voltage and Uxn represents the parameter received by the controller.

[0137] After the machine head is confirmed to be in the normal state, it is determined whether the whole machine is in the heating mode at this time. If the heating is not turned on, the whole machine is in the state of blowing cool air, and the heating component 104 remains in the normal state. And the controller 102 needs to determine whether the user has pressed the up and down shaking function at this time. If not, the parameter value received by the controller 102 at this time should always remain as the Ux1 received last time. If yes, the angle of the heating component 104 and the angle of the up and down shaking should be kept in synchronization at this time. The controller 102 will turn on the stepper motors of the two components at the same time. During this process, the angle parameter value received by the controller 102 will follow the cycle of the up and down shaking, and will always output the corresponding level signal.

[0138] If the controller 102 receives an instruction from the user to turn on the heating function, the heating component 104 will rotate to a state parallel to the air outlet. At this time, it is also necessary to determine whether to turn on the up and down shaking. After turning on, the heating component 104 and the up and down shaking stepper motor work simultaneously, and the heating element and the air outlet remain in a vertical state. During the entire working process, the parameter value received by the controller 102 will change with the change of the component movement angle. Due to the downward force of gravity, the greater the rotation angle, the more the conductive sphere moves downward, and the output parameter value changes repeatedly within a certain range (the range of parameter value changes during this rotation process can be set according to the specific conditions such as the size of the spring deformation and the synchronization accuracy requirements with the shaking rotation).

[0139] When the fan is not heating, it reduces the obstruction of the air inlet and allows the up and down shaking function to be turned on. The heating element component rotates synchronously and always remains perpendicular to the air outlet, so that the whole machine has a larger air intake in the same power and the same scene in the cool air mode, and the effect of blowing and cooling is better. After turning on the heating, the heating element is parallel to the air outlet, so that the heating element covers the entire air inlet to the greatest extent, making the air blown out at a higher temperature and better heating effect. This maximizes the air outlet effect of the fan and saves more electricity.
