The invention provides an electric toothbrush head, which comprises a brush rod, a guide sleeve, a transmission drive rod, a square-head brush, a bracket, a rotary round-head brush and a rotating shaft, wherein the guide sleeve is arranged in the brush rod; the transmission drive rod is arranged in the guide sleeve; the bracket is arranged at one end of the brush rod; the square-head brush is arranged on the bracket in a manner of swinging up and down; the rotary round-head brush is rotationally arranged at one end of the brush rod, and is adjacent to the square-head brush; the transmission drive rod penetrates through the square-head brush and is connected with the rotary round-head brush; the rotating shaft is arranged at the lower end of the rotary round-head brush; a drive shaft is arranged at one end of the rotary round-head brush; and a curved surface matched with the drive shaft is arranged on the back surface of the square-head brush. The electric toothbrush head is simple in structure and good in cleaning effect; the transmission drive rod extends into a transmission clamping groove of the rotary round-head brush to directly drive the rotary round-head brush to carry out rotary movement; and meanwhile, the square-head brush is driven to vertically swing up and down by virtue of the action force of the drive shaft of the rotary round-head brush on the curve of the square-head brush which swings up and down, so as to realize three-dimensional multi-directional movement of bristles.
Description
technical field [0001] The invention relates to the technical field of toothbrushes, in particular to an electric toothbrush head. Background technique [0002] Toothbrush is a kind of utensil for cleaning teeth that is used in people's daily life. Common electric toothbrushes currently on the market mainly have brush head vibration motion, brush head clockwise and counterclockwise rotation, brush head relative to toothbrush carrier sideways and forward, backward linear motion and other motion modes. The movement mode of these toothbrush heads, the drive mechanism of the brush head and the movement of the toothbrush change from relatively simple to relatively complex, and the movement mode still stays in the two-dimensional movement of the bristles. How to break the original design concept and make the brush head realize three-dimensional movement? While cleaning the teeth, the bristles automatically press up and down to massage the gums and gums. Many R&D personnel have al...
