[0026] The voltage detection module 240 can be selected in a conventional resistance type voltage dividing circuit, and the energy storage module 260 can be selected in a conventional storage battery, and in the normal use state, the air outlet module 210, the control module 220 and the induction receiving piece 230 can be powered by the power supply, and after the power supply is powered off, the energy storage module 260 is used to supply power to the air outlet module 210, the control module 220 and the induction receiving piece 230.

[0027] The power supply switching module 250 can be selected in a conventional charge-discharge circuit. In the first working state, the energy storage end of the power supply switching module 250 and the output end of the power supply switching module 250 are disconnected, the power supply can be rectified and voltage-regulated through the charge-discharge circuit to adjust the appropriate voltage to supply power to the air outlet module 210, the control module 220, and the induction receiver 230, and at the same time, the energy storage module 260 is charged. In the second working state, the power supply end of the power supply switching module 250 and the energy storage end of the power supply switching module 250 are disconnected, the power supply end of the power supply switching module 250 and the output end of the power supply switching module 250 are disconnected, and the energy storage module 260 supplies power to the air outlet module 210, the control module 220, and the induction receiver 230 through the charge-discharge circuit.

[0028] In addition, the control module 220 and the main control module 120 can be wirelessly connected through Bluetooth, radio frequency, infrared, WiFi, and the like.

[0029] The control method comprises controlling the power supply switching module to be in the first working state, and controlling the air outlet module to operate at a set air outlet speed and a set air outlet direction. When the fluctuation amplitude of the power supply voltage reaches a fluctuation threshold value, a wind continuation control step is performed, such as Figure 4 As shown, the wind continuation control step comprises: S310, determining an air outlet direction range according to the interaction direction, the air outlet direction range being used to limit the range of the air outlet direction of the air outlet module; S320, controlling the air outlet module to rotate to traverse different air outlet direction position points in the air outlet direction range, and correspondingly acquiring the wind flow speed fed back by the wind speed sensor at each air outlet direction position point; S330, screening the air outlet direction corresponding to the air outlet direction position point corresponding to the maximum wind flow speed to set as the wind continuation direction, and controlling the air outlet module to rotate to the wind continuation direction; S340, when the power supply voltage is zero, controlling the power supply switching module to switch to the second working state, and controlling the air outlet module to operate at the regulated air outlet speed to blow air.

[0030] In the normal use state, the air outlet speed of the air outlet module 210 can be adjusted by adopting stepless modulation or multi-grade adjustment. The air outlet module 210 controls the motor to rotate to the corresponding direction according to the set air outlet direction, and then controls the fan to rotate to blow air according to the set air outlet speed.

[0031] It can be understood that the user will place the induction terminal 100 near the user during use, and therefore, the wind flow speed detected by the induction terminal 100 is approximately the wind flow speed at the position of the user.

[0032] When the air outlet module 200 is placed in the environment, there is also natural wind flow flowing in the environment. Since the user sets the air outlet direction at will, the air outlet module 210 blows air according to the set air outlet direction, and the wind flow and the natural wind are mixed. The wind flow speed at the user's location may not reach a large value.

[0033] The voltage detection module 240 samples the power supply voltage. When the fluctuation amplitude of the power supply voltage reaches the fluctuation threshold, it means that there is a risk of power failure in the future. The power supply can be direct current or three-phase alternating current according to the actual local power consumption. The fluctuation threshold can be set to 10-30V, or the fluctuation threshold can be set to ±10% of the local standard power supply voltage. At this time, the wind continuation control step is executed, the interaction direction of the inductive receiving part 230 inductively cooperating with the inductive matching part 130 is obtained to roughly determine the direction of the user relative to the air outlet module 200, and the air outlet direction range is determined according to the interaction direction. Then the air outlet module 200 traverses different air outlet position points in the air outlet direction range, and the wind speed sensor 110 on the inductive terminal 100 feeds back the wind flow speed to determine which air outlet position point the air outlet module 200 rotates to. The wind flow speed near the user is larger, that is, as the wind continuation direction, the control air outlet module 210 rotates to the wind continuation direction and blows air according to the user's set air outlet speed. If the power supply is powered off in the future, the power supply voltage is zero, the power supply switching module 250 is switched to the second working state, the energy storage module 260 is powered, and the air outlet module 210 is controlled to blow air according to the control air outlet speed. Generally, the control air outlet speed is less than the set air outlet speed. The actual situation of the use area can be set by the manufacturer, or it can be set by the user according to his own needs. Of course, when the control air outlet speed can be changed, the higher the initial value of the control air outlet speed, the faster the consumption of electric energy. In addition, since the air outlet module 210 has been rotated and adjusted to the wind continuation direction, the wind flow output by the air outlet module 200 according to the control air outlet speed combined with the wind flow in the environment can maintain a reasonable wind flow to provide the user with basic heat dissipation supply. The design maintains the wind flow supply and improves the wind flow utilization rate, reasonably uses energy storage, reduces electric energy consumption, and prolongs the wind continuation time.

[0034] It should be noted that before power failure, as long as the fluctuation amplitude of the power supply voltage reaches the fluctuation threshold, the control air outlet module 210 rotates to traverse each wind detection position point in the wind detection direction range. It is possible that power failure occurs during the traversal of each wind detection position point in the wind detection direction range. If power failure occurs at this time, power supply is performed by the energy storage module 260 to continue the operation of traversing each wind detection position point in the wind detection direction range. If the operation of traversing each wind detection position point in the wind detection direction range is completed and power failure still does not occur, the air outlet module 210 can be controlled to rotate to the wind continuation direction and blow air at the set air outlet speed, so as to ensure that after power failure, no other actions of the air outlet module 210 are required to waste electric energy, and only the air outlet speed needs to be adjusted. When a second fluctuation does not occur after a period of time, it can be considered that the fluctuation is only occasional. Therefore, in some embodiments of the present application, when the power supply voltage is zero, the power supply switching module 250 is switched to the second working state, and the air outlet module 210 is controlled to run and blow air at the regulated air outlet speed. The delay time is recorded when the fluctuation amplitude of the power supply voltage reaches the fluctuation threshold. When the power supply voltage is zero, the power supply switching module 250 is switched to the second working state, and the air outlet module 210 is controlled to run and blow air at the regulated air outlet speed. When the delay time reaches the delay threshold, the air outlet module 210 is controlled to resume running at the set air outlet direction. When the fluctuation amplitude of the power supply voltage reaches the fluctuation threshold again during the recording of the delay time, the delay time is cleared.

[0035] The delay threshold can be set to 60s, 80s, 120s, etc. The air outlet module 200 can be provided with a timer. When the fluctuation amplitude of the power supply voltage reaches the fluctuation threshold, the delay time of the timer is cleared, and then the delay time is recorded again. When the power supply voltage is zero at this time, it means that the power supply is powered off, the power supply switching module 250 is switched to the second working state, and the air outlet module 210 runs at the regulated air outlet speed. If the delay time reaches the delay threshold, it means that the fluctuation is only an accidental event, and the wind continuation regulation step is cancelled. If fluctuation occurs again, it means that the risk has not been eliminated, and the delay is restarted to prepare for the possible power failure in the future.

[0036] In some embodiments of the present application, as shown in Figure 2 The wind detection direction range is determined according to the interaction direction. The wind detection direction range a is determined by a sector region centered on the interaction direction and having a preset angle.

[0037] The preset angle of the fan-shaped area can be set by the manufacturer and the user according to actual conditions, for example, 60°, 80° or 120°, and the air outlet module 210 can rotate in the wind detection direction range to find a position point at which the wind speed at the user's location is relatively fast as the next wind direction.

[0038] Considering that the set wind direction set by the user at the beginning has a certain reference value, in some embodiments of the present application, as shown in FIG. 2B, the wind detection direction range is determined according to the interaction direction and the set wind direction. Figure 3 The balanced direction is obtained according to the center between the interaction direction and the set wind direction. The wind detection direction range β is determined according to the balanced direction as the center and the fan-shaped area with a preset angle.

[0039] Considering the user's setting, the center between the interaction direction and the set wind direction is calculated as the balanced direction, and then the balanced direction is taken as the center to determine the wind detection direction range in cooperation with the fan-shaped area with a preset angle. At this time, the determined wind detection direction range can be compatible to the direction set by the user and the direction near the interaction direction, so as to find a position point at which the wind speed at the user's location is relatively fast as the next wind direction.

[0040] In some embodiments of the present application, the control of the rotation of the air outlet module 210 to traverse the wind detection position points in the wind detection direction range, and the acquisition of the wind flow speed feedback by the wind speed sensor 110 at each wind detection position point include: The wind detection direction range is evenly divided into a preset number of direction intervals, and the nodes at the two ends of the wind detection direction range and the nodes between adjacent direction intervals are taken as the wind detection position points. The air outlet module 210 is rotated to the wind detection position point at the head end of the wind detection direction range, and the air outlet module 210 is controlled to rotate towards the wind detection position point at the tail end of the wind detection direction range starting from the wind detection position point at the head end of the wind detection direction range, and after staying at each wind detection position point for a wind detection time, the air outlet module 210 rotates to the next wind detection position point, wherein the air outlet speed of the air outlet module 210 is the same at each wind detection position point. The wind flow speed feedback by the wind speed sensor 110 is acquired when staying at each wind detection position point.

[0041] ​Taking the wind detection direction range of 60° as an example, the span of the direction interval can be equally divided to be 5°, 10°, etc., the air outlet module 210 is first rotated to a wind detection position point at the first end of the wind detection direction range, i.e., a position of 0°, the air outlet module 210 stays at this position for a wind detection time and keeps air outlet, the air outlet speed at each wind detection position point is the same, which can be a set air outlet speed or an additional wind detection air outlet speed, and the specific value is set by the manufacturer or the user, during the stay time, the wind speed sensor 110 detects multiple wind flow speeds and feeds back to the control module 220, each wind detection position point adopts the same way to collect, and finally the size of the wind flow speed at each wind detection position point is judged.

[0042] Specifically, in the wind speed sensor 110 feedback wind flow speed obtained when staying at each wind detection position point includes: N wind flow speed values are obtained at each wind detection position point at a preset frequency; The average value of the N wind flow speed values is calculated as a wind flow reference value; The air outlet direction of the wind detection position point corresponding to the maximum wind flow speed is screened out and set as the continuous air outlet direction. The maximum value is screened out from the wind flow reference values at each wind detection position point, and the air outlet direction of the wind detection position point corresponding to the maximum value is set as the continuous air outlet direction.

[0043] The preset frequency can be set by the manufacturer or the user according to the actual situation, and it can be understood that the period corresponding to the preset frequency can be set to 0.2s, 0.5s, etc., which means that one wind flow speed value is collected in each period, and the wind detection time can also be set by the manufacturer or the user according to the actual situation, for example, the wind detection time is 2s, the period corresponding to the preset frequency is 0.2s, and 10 wind flow speed values can be collected, i.e., N=10, and the average value of the 10 wind flow speed values is calculated as the wind flow reference value, it can be understood that there is natural wind flow in the environment, although the wind flow in the environment is constantly changing, but the wind detection time is set for a certain period of time to reduce the influence of the change of the wind flow, at the same time, the combined wind flow after the air outlet wind flow and the natural wind flow can also be combined, the wind flow speed feedback by the wind speed sensor 110 is used to represent the influence of the combined wind flow on the position of the user, and the better continuous air outlet direction of the air outlet module 210 is found.
