[0002] Different from sonic electric toothbrushes, rotary electric toothbrushes clean by rotating the bristle disk in the plane of the toothbrush. Common rotary motors are mostly electric toothbrush series produced by Oral-B. Existing rotary electric toothbrushes are arranged with a rotary motor for unidirectional rotation or reciprocating rotation at a limited angle, and a conversion mechanism is connected to convert the axial motion of the motor in the vertical direction into rotation of the bristle disk in another direction.

[0003] Currently common rotating toothbrush heads, such as Figure 1 As shown, the hair planting plate 100 is buckled into the base 200, and the base 200 is enclosed on the outer peripheral side of the hair planting plate 100. After the buckle is pre-positioned, the industry practice is to fix the contact part of the hair planting plate 100 and the base 200 by ultrasonic welding. This method will reduce the hair planting area of ​​the hair planting plate, which is not conducive to the fixation of the brush in the front-end process; secondly, there will be a circle of welding gaps on the hair planting surface, which will cause mold to grow in the welding gaps and blacken in a long-term brushing environment, affecting hygiene and appearance. Summary of the invention
