Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.

In this embodiment, as shown in fig. 1 to 6, an electric toothbrush with a reciprocating rotating brush head comprises a handle 1, a forward and reverse rotating motor 2 arranged in the handle 1, a brush rod 3 movably connected with the handle 1, and a brush head 4 movably connected with the brush rod 3, wherein a deflection mechanism 5 and a rotating mechanism 6 are arranged in the brush rod 3, a rotating shaft of the forward and reverse rotating motor 2 is connected with one end of the deflection mechanism 5, the other end of the deflection mechanism 5 is connected with one end of the rotating mechanism 6, the other end of the rotating mechanism 6 is connected with the brush head 4, and the forward and reverse rotating motor 2 drives the deflection mechanism 5, the rotating mechanism 6 and the brush head 4 to rotate in a reciprocating manner.

Furthermore, the deflecting mechanism 5 comprises an eccentric wheel 51, an eccentric column 52 is arranged on the eccentric wheel 51, and the eccentric column 52 is connected with one end of the rotating mechanism 6.

Furthermore, the rotating mechanism 6 includes a rotating seat 61 and a rotating rod 62, one end of the rotating rod 62 is fixedly connected with the rotating seat 61, and the eccentric column 52 is inserted into the rotating seat 61.

Furthermore, a groove 63 is formed at the bottom of the rotating seat 61, the eccentric column 52 is inserted into the groove 63, and the other end of the rotating rod 62 is movably connected with the brush head 4; wherein, the eccentric column 52 drives the rotating seat 61, the rotating rod 62 and the brush head 4 to rotate in a reciprocating manner.

It should be noted that the eccentric column is far away from the center of a circle of the eccentric wheel, is clamped with the long groove, generates a rotating force when the forward and reverse rotation motor rotates forward and reverse, and drives the rotating rod connected with the eccentric wheel to rotate in a reciprocating manner.

In this embodiment, a cavity is formed in the brush rod 3, the rotating mechanism 5 is disposed in the cavity, and the brush rod 3 rotates reciprocally relative to the cavity.
