Electric toothbrush head

Abstract

The invention relates to an electric toothbrush head, belonging to the field of electric toothbrushes. When an existing electric toothbrush is used for brushing teeth, the tooth brushing effect is not good, and the good effect of massaging relevant positions in the mouth cavity in an oscillatory way cannot be achieved. The electric toothbrush head comprises a brush head casing, a transmission shaft, a bristle seat and a connection mechanism arranged between the bristle seat and the brush head casing. The transmission shaft comprises a transitional section, a supporting section and a transmission section, which are sequentially connected into a whole. The bristle seat is respectively provided with a right transmission arm, a left transmission arm and a bump. The bump is provided with a through groove. The transmission section of the transmission shaft is assembled between the right transmission arm and the left transmission arm. The transitional section of the transmission shaft is assembled with the through groove on the bump. The supporting section of the transmission shaft arranged between the bristle seat and the brush head casing is assembled with the connection mechanism. The electric toothbrush head, together with a toothbrush barrel, a toothbrush handle and the like, are combined into a toothbrush product. When people use the toothbrush, satisfactory tooth brushing effect can be achieved, and the good effect of massaging the relevant positions in the mouth cavity in an oscillatory way can also be achieved.

Description

technical field [0001] The invention relates to the field of electric toothbrushes, in particular to an electric toothbrush head. Background technique [0002] The Chinese Utility Model Patent No. 02271490.1 discloses an electric toothbrush, which includes a brush cylinder, a brush handle and a brush head with bristles. The rod is characterized in that the end of the connecting rod is provided with a swing mechanism that drives the brush head to perform reciprocating yaw motion. The swing mechanism is composed of a crank-shaped hook on the upper part of the connecting rod and a hook groove on the inner wall of the brush head where the hook can be clamped, wherein the width of the hook groove is slightly larger than the diameter of the connecting rod. Driven by the hook on the upper part of the connecting rod, the brush head can swing back and forth along the brush handle. This electric toothbrush and its similar electric toothbrush that adopts rotary transmission shaft tra...

AI Technical Summary

Problems solved by technology

This electric toothbrush and similar electric toothbrushes that adopt rotary transmission shaft transmission, the supporting section of its transmission shaft is mostly arranged in the end of the brush handle, the deficiency of this structure is: transmission shaft does not extend to the hair seat and the brush head The space between the casings, the supporting section of the transmission shaft is offset in the end of the brush handle, the design of the transmission shaft cannot use the space between the hair seat and the brush head casing, the brush head can only reciprocate along the brush handle, people use When this electric toothbrush and similar electric toothbrushes that adopt rotary drive shaft transmission are used for brushing teeth, the brushing effect is not ideal, and the good effect of vibration massage on the relevant parts in the oral cavity cannot be reached.
