Abstract

The invention relates to a light-emitting device utilizing piezoelectric ceramic bidirectional coupling power generation. The light-emitting device comprises LED lamps, two electrode plates and a piezoelectric ceramic plate. The two electrode plates are electrically connected with the LED lamps and comprise the upper electrode plate and the lower electrode plate. The piezoelectric ceramic plate is clamped between the upper electrode plate and the lower electrode plate. A buffer is arranged among the LED lamps and the upper electrode plate, and an energy taking ring is arranged below the lower electrode plate. The upper electrode plate, the lower electrode plate, the piezoelectric ceramic plate, the buffer and the energy taking ring are all of a hollow annular structure. The light-emitting device has the beneficial effects that by means of the light-emitting device, the structure of an energy converter handle is simplified, and arrangement is easier; and meanwhile a mainframe circuit module of an ultrasonic scaler or a piezosurgery machine is simplified, cost is reduced, and the risk that feedback errors of a mainframe happen due to abnormal power supply of the LED lamps is eliminated. The invention further discloses a handle of ultrasonic dental treatment equipment with the light-emitting device.

Description

technical field [0001] The invention relates to a light-emitting device which uses piezoelectric ceramics to generate electricity through two-way coupling and a handle containing the same. Background technique [0002] Ultrasonic dental treatment equipment is used for dental clinical cleaning and surgery. Its types include ultrasonic tooth scaler, ultrasonic periodontal treatment instrument, ultrasonic bone cutting surgery equipment, etc. The working principle of these equipment is to transfer electric energy through transducers. The mechanical energy converted into ultrasonic vibration is transmitted to different types of working heads connected to the transducer to realize the functions of its equipment. For example, ultrasonic dental scalers can be used to remove dental calculus, smoke spots, and bacterial plaque. At present, ultrasonic dental treatment equipment is mainly composed of a host, a power supply, a foot switch, a handle connection and a handle, and a transduce...
