摘要： 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.

摘要： The present disclosure relates generally to oral health products, such as electric toothbrushes. In one example, the electric toothbrush includes a housing, an output shaft positioned within and extending out of the housing, a magnetic assembly positioned within the housing and configured to impart an oscillation motion to the output shaft, and a spring positioned within the housing. The spring includes a first end non-rotatably coupled to the housing and a second end non-rotatably coupled to the output shaft, such that the spring twists as the magnetic assembly oscillates the output shaft to amplify the oscillation motion of the output shaft generated by the magnetic assembly.

摘要： An electric toothbrush that detects plaque on the teeth, ensures accurate plaque detection, and performs cleaning of plaque. The electric toothbrush may include a body having a gripping part and a stem with a brush unit detachably coupled to the body. The electric toothbrush may include a light emitting element for emitting light onto the tooth and a light receiving element for receiving light that reflects off of the tooth. A controller may be included to determine an amount of plaque on the tooth based on the amount of reflected light detected. The electric toothbrush may also include a fluid dispensing system that dispenses fluid based on the amount of reflected light detected. In some aspects, the electric toothbrush may operate in multiple oscillation modes, and it may only dispense fluid in some of the modes but not all of the modes.
