According to the electric toothbrush head of the present invention, the production and assembly processes are effectively simplified, the existing restriction factors of complicated structure, multiple fault points, poor safety, high production cost and the like which influence the large-scale production and use of the double-rod sequential electric toothbrush head in the assembly mode are overcome, and the low-cost and large-scale production of an enterprise are facilitated. The hidden troubles that the bristles are fell off and the bristles and the front parts of the drive rods are separated from the brush rod partition board are eliminated, so the use safety is improved.Linvention concerne une tête de brosse à dents électrique pour lhygiène buccale, et, en particulier, lamélioration dune tête de brosse à dents électrique séquentielle à deux tiges.
