摘要： A head structure of a brush appliance comprises a frame movably connected with a head driving shaft, driving bristle retainers connected with and driven by the head driving shaft, and driven bristle retainers which and the driving bristle retainers are alternatively arranged with each other. In the head structure, the driven bristle retainers are driven by the driving bristle retainers from the frame in a constrained mode and move around a respective motion axis. The driving bristle retainers have protrusions. The driven bristle retainers have bevel surfaces which correspondingly cooperate with the protrusions. At least one driven point on at least one of bevel surfaces is closer to the driving bristle retainers than a contact point or a contact line or a contact surface of the at least bevel surface and the corresponding protrusions. Thereby the driven bristle retainers are driven by the driving bristle retainers in the moving process.
