Abstract
Disclosed are an acoustic wave type electric cleaning and care tool and a pressure warning device for same. Upper and lower drive shaft bearings are fixed on a drive shaft. The upper bearing is fixed in left and right brackets by a fixed surface and is stationary. The lower bearing is fixed in the brackets by a upper fixed surface and perform a relative movement such that the lower bearing is separated from or contact with the upper fixed surface. The alarm device comprises a lever, a light-emitting element and a photosensitive element. The lever is provided with a shielding surface and/or a light-shielding protrusion. Light energy is changed by the change of gap between the shielding surface and/or the light-shielding protrusion and the photosensitive element. The change in electrical performance parameters of the photosensitive element is detected to acquire a load pressure on a cleaning element and realize pressure alarm.
