Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flow chart of an electric fan control method according to an exemplary embodiment. As shown in fig. 1, the electric fan control method includes the following steps:
step 101: receiving a rotation signal corresponding to the position of a target user, wherein the rotation signal has a target rotation amplitude and target rotation position information;
step 104: and controlling the fan head of the electric fan to rotate back and forth in the target rotating amplitude angle towards the target rotating azimuth.
For example, when the target user is located in the southeast direction of the fan, the rotation signal received by the electric fan is the southeast direction as the target rotation direction, and the target rotation amplitude angle is 90 degrees for example; the target rotation amplitude may be a default setting of the fan control system or set by the user as desired. Accordingly, the fan head of the electric fan is controlled to rotate back and forth within 90 degrees toward the southeast direction.
For another example, when the target user is located in the south-plus-south direction, the rotation signal received by the electric fan is the target rotation direction in the south-plus-south direction, and the target rotation amplitude is, for example, 120 degrees. Accordingly, the fan head of the electric fan is controlled to rotate back and forth within 120 degrees towards the south-facing direction.
In the electric fan control method of the embodiment, the electric fan rotates in a target rotating amplitude angle with a specified size and automatically faces to a target rotating direction, so that a rotating area for useless air supply is reduced, the air supply use efficiency of the electric fan is maximized, and user experience is optimized.
Fig. 2 is a flowchart of an electric fan control method according to another exemplary embodiment. As shown in fig. 2, the electric fan control method includes:
step 201: receiving a rotation signal corresponding to the position of a target user, wherein the rotation signal comprises a first control signal representing a starting angle and a second control signal representing a stopping angle;
step 202: when the first control signal is received, controlling the fan head to rotate from the starting angle in the direction opposite to the original rotation direction;
step 203: controlling the fan head to rotate from the end angle towards the start angle direction when the second control signal is received;
step 204: and controlling the fan head to face a target rotation azimuth pointed by the starting angle and the ending angle and to rotate back and forth within a target rotation amplitude angle defined by the starting angle and the ending angle.
For example: after the electric fan is powered on, a starting signal sent by a physical key of the electric fan, WiFi (wireless fidelity) of a mobile phone or infrared rays is received, and non-rotation air supply is carried out; when a signal of a rotation command is received, the fan head rotates in a fixed direction (for example, clockwise or anticlockwise direction); the target user may send a first control signal indicating a start angle and a second control signal indicating an end angle, respectively, according to a desired blowing range while the fan head is oriented toward itself. When the electric fan receives a first control signal, the angle of the fan head is the starting angle, and then the fan head rotates from the starting angle in the direction opposite to the original rotating direction. When the electric fan receives the second control signal again, the angle of the fan head is the ending angle, and then the fan head rotates from the ending angle to the starting angle. The area between the ending angle and the starting angle represents the target rotation azimuth, and the angle difference between the ending angle and the starting angle is the target rotation amplitude.
In the electric fan control method of the embodiment, the electric fan receives the starting angle and the ending angle set during the period that the fan head faces the target rotating direction, so that the fan head is controlled to rotate back and forth in the selected target rotating amplitude angle towards the target rotating direction, the rotating angle of the electric fan is free from redundancy, the air supply use efficiency of the electric fan is maximized, and the user experience is optimized.

step 304: and controlling the fan head of the electric fan to rotate back and forth in the target rotating amplitude angle towards the target rotating azimuth.
For example, the target user turns on a fan control APP on a smart phone or a PAD, and after drawing a target rotation direction and a target rotation argument (see a shaded sector area in fig. 7) on a fan control interface, transmits the target rotation direction and the target rotation argument to the electric fan control device in a wireless manner. At this time, the electric fan control device receives the target rotating amplitude and the target rotating azimuth which are selected and set in the fan control interface of the mobile terminal, and further controls the fan head of the electric fan to rotate back and forth in the target rotating amplitude towards the target rotating azimuth.
In the electric fan control method of the embodiment, the electric fan receives the target rotation direction and the target rotation amplitude set by the target user on the fan control interface, so that the fan head is controlled to rotate back and forth in the selected target rotation amplitude towards the target rotation direction, the rotation angle of the electric fan is free from redundancy, the air supply use efficiency of the electric fan is maximized, and the user experience is optimized.
Fig. 4A is a flowchart of an electric fan control method according to yet another exemplary embodiment. As shown in fig. 4A, the electric fan control method includes:
step 400: detecting the position of a target user, and determining a target rotation amplitude and a target rotation direction by taking a virtual connecting line of the fan head and the position of the target user as a reference;
in this step, when the target user is a single user, as shown in the left diagram of fig. 4B, a virtual connection line between the fan head a and the target user B is an angular bisector (broken line) of the target rotation argument (β 1+ β 2), that is, the target rotation argument β 1+ β 2, and β 1 ═ β 2; alternatively, as shown in the right diagram of fig. 4B, when the target users are a plurality of target users B1 to Bn dispersed at a plurality of positions, a virtual connecting line (broken line) between a midpoint position between a first target user B1 located on one side and a second target user Bn located on the other side and the fan head a is an angular bisector of a target rotation argument (that is, a target rotation argument β 3+ β 4 and β 3 β 4) that is larger than the rotation argument β 0 corresponding to the distance between the first target user and the second target user.
Step 401: receiving a rotation signal corresponding to the position of a target user, wherein the rotation signal has a target rotation amplitude and target rotation position information;
step 404: and controlling the fan head of the electric fan to face the target rotating azimuth and rotate back and forth in the target rotating amplitude.
In the electric fan control method of the embodiment, the electric fan automatically detects the position of the target user, and the target rotation amplitude and the target rotation direction are determined by taking the virtual connecting line between the fan head and the position of the target user as a reference, so that the fan head is controlled to rotate back and forth towards the target rotation direction in the selected target rotation amplitude, the rotation angle of the electric fan is free from redundancy, the air supply use efficiency of the electric fan is maximized, and the user experience is optimized.
