The invention relates to a transmission structure of an electric toothbrush and the electric toothbrush. The transmission structure comprises a vibration rod and a motor, wherein an inner cavity of the vibration rod is provided with a half coupler, a pressure spring, a transmission rod and an eccentric wheel; input and output ends of the eccentric wheel are cylinders on the same axis, and the axisof the eccentric wheel and the axes of the input and output ends of the eccentric wheel are not located on the same straight line; the input end of the eccentric wheel is connected with an output endof the transmission rod. The transmission structure has the advantages that due to the arrangement of the pressure spring, the problems are effectively solved that an electric toothbrush motor is overstressed, generated current is overlarge, the electric quantity of a battery is wasted, and the service life of the electric toothbrush is influenced; the service life of the battery is prolonged, and the service life of the electric toothbrush is prolonged.; through improvement of the eccentric wheel structure, the vibration effect of the electric toothbrush is effectively improved, and the cleaning capability of the electric toothbrush is enhanced.
Description
technical field [0001] The invention relates to the field of daily necessities, in particular to a transmission structure of an electric toothbrush and the electric toothbrush. Background technique [0002] In the prior art, the motor of the electric toothbrush and the eccentric wheel are tightly connected through the transmission rod, presenting an integrated fastening assembly method. This type of connection method has no elastic buffer zone. The assembly method of this type of connection structure must require the motor, transmission The centers of the rod, eccentric wheel and vibrating rod are guaranteed to be on the same straight line. During the production and assembly process, it is easy to appear that the centers of the motor, power transmission rod, eccentric wheel and vibrating rod are not on the same straight line, which will cause the vibrating rod to press the eccentric wheel. tight, resulting in excessive stress on the motor, excessive current, waste of electri...
