Abstract
A toothbrush head includes: a brush rod and a brush head assembly connected to the brush rod. The brush head assembly includes a bristle fixing member and a body. The bristle fixing member includes a first side surface and a second side surface. The first side surface is provided with a plurality of bristles. The body includes a first end and a second end. The second end is connected to the brush rod, and the first end is extended to form a supporting beam. The supporting beam is located on a side of the bristle fixing member away from the plurality of bristles. An elastomer is filled between the supporting beam and the bristle fixing member, and a pivot-forming structure is provided on the supporting beam and/or the bristle fixing member.

A toothbrush head, comprising a brush rod and a brush head assembly connected to the brush rod;
- the brush head assembly comprising:
- a bristle fixing member comprising a first side surface and a second side surface opposite to each other, the first side surface being provided with a plurality of bristles;
- a body comprising a first end and a second end opposite to each other, the second end being connected to the brush rod, a supporting beam extending from the first end, the supporting beam being located on a side of the bristle fixing member away from the plurality of bristles;
- an elastomer being provided between the supporting beam and the bristle fixing member, and a pivot-forming structure being provided on the supporting beam to allow the supporting beam and the bristle fixing member to oscillate relative to each other along an axis defined by the pivot-forming structure;
- wherein the supporting beam comprises a first surface and a second surface opposite to each other, the first surface of the supporting beam faces the bristle fixing member, a first protrusion is provided on the first surface of the supporting beam;
