Abstract

The invention discloses a control device for a fan. The control device comprises a shell (1); the internal surface (2) of the shell (1) is provided with a metal layer; a metal contact piece (4) which can sense a change signal and control the fan to work according to the sensing signal when parts of a human body (8) approach the fan is arranged on the internal surface (2); the metal contact piece (4) is connected with a controller (6) of the fan (7) through a wire; and the controller (6) is connected with the fan (7). When a hand of the human body approaches the internal surface of the shell, the hand and the internal surface serve as two poles of a capacitance, and the hand and the internal surface are electrified for a high-frequency signal. The high-frequency signal is applied to the internal surface of the shell by the controller, when the parts of the human body approach the internal surface, micro current flows from the internal surface of the shell to the parts of the human body, and if only the controller senses the change of the micro current, the controller controls the fan to change the rotation speed. The control device realizes the non-contact control and is convenient to control.

Description

technical field [0001] The invention is a fan control device, which belongs to the transformation technology of the fan control device. Background technique [0002] Existing traditional fan control methods include mechanical, remote control, light touch, etc., but these control methods require fingers to press the control buttons to control the work of the fan, and their disadvantages are troublesome operation and inconvenient control. Contents of the invention [0003] The object of the present invention is to provide a fan control device that realizes non-contact control and is simple and convenient in consideration of the above problems. The invention is reasonable in design, convenient and practical. [0004] The technical solution of the present invention is: the fan control device of the present invention includes a casing, and a metal layer is provided on the inner surface of the casing, wherein when the human body part is close to the fan, the change signal can ...
