Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Example 1: as shown in fig. 1 and 2, an electric device for an electric toothbrush includes a holder shaft 1 and a driving part 2, wherein,
the support shaft 1 is integrally formed and comprises a vibration shaft 101 and a support 102, the vibration shaft 101 is arranged at the top end of the support 102, a mounting groove 1011 matched with the brush head is formed in the vibration shaft 101, the integrally formed support shaft is strong in overall structure and not prone to damage, and the service life of the support shaft is prolonged; in order to install the brush head in a matched manner and facilitate that the brush head is not easy to fall off from the vibration shaft after being installed, the vibration shaft is provided with an installation groove in a matched manner, and the installation groove is matched with the structure in the brush head;
the bracket 102 is provided with a driving part 2; the driving part 2 is a vibration motor, the vibration motor is in a model of 130, 612 or 1220, two ends of a rotor shaft of the vibration motor 2 are respectively provided with a group of adjustable eccentric blocks 201, and the centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks is utilized to obtain an excitation force, so that the vibration frequency range of the vibration motor is large; the vibration of the vibration motor drives the bracket 102 to vibrate, the vibration of the bracket 102 drives the vibration shaft 101 at the top end to vibrate, and the vibration shaft 101 drives the brush head arranged on the vibration shaft to vibrate, so that the toothpaste is finally decomposed into fine foams to deeply clean teeth gaps.
In the present application, the support 102 is circular, specifically, the support 102 is a cylinder, and a hollow portion 1021 is arranged inside the support 102, a vibration motor is arranged in the hollow portion 1021, an opening 1023 is arranged at one end of the support 102 where the vibration shaft is not arranged, so that the motor can be conveniently installed into the support from the opening 1023; in order to match the shape of the electric toothbrush handle, the support can be set to be cylindrical, in order to reduce the size, the structure is optimized, a hollow part 1021 matched with the vibration motor is arranged in the support, and in such a setting mode, the corresponding vibration motor space is not required to be arranged in the handle, so that the size reduction of the electric toothbrush is realized, and the occupied space is reduced. Specifically, a groove 1022 may be disposed at a top end of the hollow portion 1021, and the top end of the eccentric motor is disposed in the groove 1022 in a matching manner, that is, the accommodation and fixation of the eccentric motor are achieved through the groove, so that the motor is prevented from falling out of the hollow portion, and the firmness of fixation of the vibration motor is achieved.
