Abstract

A music fan based on swing blade wind change and its control method. The music fan includes a power unit, a support unit, a humidification unit, a swing blade drive unit and a control unit; the power unit includes two fans, and the power unit is located in the casing; the support The unit includes a support structure and a shell; the moisture of the humidification unit is introduced into the shell through the moisture air inlet; the swing leaf drive unit includes: a front beam, a rear beam, a stepper linear screw motor, two optical axes, eight screws, Six swing axes, six fasteners, six rotating shafts, screw nuts, partitions, six connecting pieces, and six swing leaves; the present invention uses an open-loop control linear screw motor that converts electrical pulse signals into linear displacement. . Under non-overload conditions, the motor's speed and stopping position only depend on the frequency and number of pulses of the pulse signal, and are not affected by load changes. The angular displacement is controlled by controlling the number of pulses to achieve accurate positioning. .

Description

technical field

[0001] The invention belongs to the technical field of electromechanical integration, and in particular relates to a music fan based on swinging leaves to change wind and a control method thereof. Background technique

[0002] Household electric fans on the market mainly include ceiling fans, desk fans, and floor fans, which are mainly composed of fan motors, fan blades, front and rear grilles, connectors, swing mechanisms, bases, and switch control mechanisms. The rotation of the fan motor is controlled by the switch to drive the movement of the fan blades to achieve the effect of blowing air. At the same time, the fan blades can swing air supply within a certain range through the swing mechanism, or change the air supply direction by rotating the direction blades.

[0003] There is also a floor fan with a humidifier on the market, which consists of a base, a support base, a fan head and a humidifier. The base and the support base are detachably connected; ...
