Abstract
Described are an oscillation amplitude control component, home electrical equipment and an oscillation amplitude control method and device. The component includes: a V-shaped grooved gear, a pressure pump, a roller with a pre-formed groove and a transmission belt; the V-shaped grooved gear includes a central shaft and two frustoconical members mounted on the central shaft; lateral surfaces of two frustoconical members and the central shaft enclose a V-shaped groove; a gear is arranged on a circumference of a frustoconical member, and joined with an oscillating switch selectively; the transmission belt is configured to surround the V-shaped groove and the pre-formed groove; two frustoconical members regulate a surrounding radius of the transmission belt surrounding the V-shaped groove under control of pressure generated by the pressure pump; and the roller is fixed in an oscillating plate, and controls an oscillation amplitude of the home electrical equipment through the oscillating plate.
