[0001] The present invention relates to the technical field of fans, and in particular to an intelligent environment-aware fan and a control method thereof. Background Art

[0002] Traditional fans have a single function and cannot automatically adjust the wind direction according to environmental changes. In actual use, users often need to manually adjust the angle of the fan to adapt to different environmental requirements. For example, when the window is opened, users hope that the fan can automatically adjust the angle to achieve a convection effect. Summary of the invention

[0003] The purpose of the present invention is to provide an intelligent environment-aware fan and a control method thereof, aiming to solve the technical problem in the prior art that the fan cannot automatically adjust the angle when the window is opened.

[0004] In order to solve the above technical problems, the technical solution of the present invention is:

[0005] An intelligent environment-sensing fan comprises a base, a fan head, a fan controller, and a first driving mechanism for driving the fan head to rotate, wherein the fan head comprises fan blades and a second driving mechanism for driving the fan blades to rotate; a detection element for detecting whether the window sash is open is provided on the window; the fan controller is electrically connected to the first driving mechanism and the second driving mechanism, and the fan controller is signal-connected to the detection element.

[0006] Preferably, a support shaft is installed at the bottom of the fan head, the support shaft is rotatably installed on the base, and the first driving mechanism drives the support shaft to rotate.

[0007] Preferably, the first driving mechanism includes a driven gear sleeved on the lower end of the supporting shaft, a driving gear rotatably mounted on the base, and a motor driving the driving gear to rotate, and the driving gear and the driven gear are meshingly connected.

[0008] Preferably, the detection element is a contact sensor mounted on the window frame.

[0009] Preferably, an infrared sensor is provided on the fan, and the infrared sensor is connected to the fan controller signal.

[0012] Preferably, the fan controller is mounted on the base.

[0013] The intelligent environment-aware fan control method uses an intelligent environment-aware fan and includes the following steps:

[0014] Step 1: The detection element detects whether the window is open. If the window is open, the detection element transmits a signal to the fan controller;

[0015] Step 2: After receiving the signal, the fan controller controls the first driving mechanism to adjust the angle of the fan head so that the fan head faces the window;

[0016] Step 3: The fan controller controls the second driving mechanism to drive the fan blades to rotate to achieve a convection effect.

[0017] Preferably, in step one, if the detection element detects that the window is closed, when the air conditioner turns on the cooling mode, the infrared sensor detects the infrared signal emitted by the air conditioner and transmits the signal to the fan controller; the fan controller controls the action of the first drive mechanism, and the first drive mechanism drives the fan head to shake its head; the fan controller controls the action of the second drive mechanism, and the second drive mechanism drives the fan blades to rotate, thereby realizing whole-house circulation.

[0018] After adopting the above technical solution, the beneficial effects of the present invention are:

[0019] 1. The intelligent environment-sensing fan of the present invention can detect whether the window is open. When the window is open, the fan is directed toward the window to achieve a convection effect.

[0020] 2. The intelligent environment-sensing fan of the present invention can control the fan head to shake and the fan blades to rotate when the windows are closed and the air conditioner is turned on the cooling mode, thereby achieving whole-house circulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] Step 3: The fan controller 12 controls the second driving mechanism to drive the fan blades to rotate to achieve a convection effect.

[0068] Among them, in step one, if the detection element detects that the window 2 is closed, when the air conditioner 3 turns on the cooling mode, the infrared sensor 19 detects the infrared signal emitted by the air conditioner 3 and transmits the signal to the fan controller 12; the fan controller 12 controls the action of the first drive mechanism, and the first drive mechanism drives the fan head 11 to shake its head; the fan controller 12 controls the action of the second drive mechanism, and the second drive mechanism drives the fan blades to rotate to realize whole-house circulation.
