Abstract

The utility model relates to an all-dimensional toothbrush for cleaning back teeth, and belongs to the technical field of oral cavity and tooth cleaning tools. According to the technical scheme, bristles on a back toothbrush head (2) are integrally of a plane structure and are perpendicular to the toothbrush head; bristles on a front toothbrush head (3) are integrally of a V-shaped structure, in other words, the bristles are separated in the middle in the length direction of the toothbrush head, the bristles in the middle are shortest, the bristles on the two sides become longer and longer, the included corner between two lines of the V-shaped structure is in a V shape, the V-shaped corner of the bristles, close to the back toothbrush head, on the front toothbrush head is largest, the V-shaped corner of the bristles, far away from the back toothbrush head, of the front toothbrush head is smallest, and the V-shaped angle smoothly changes from large to small. The included angle between the bristles on the front toothbrush head and the front toothbrush head vertical line ranges from 5 degrees to 10 degrees, and the bristles on the front toothbrush head incline outwards. The all-dimensional toothbrush has the advantages that the internal space of the oral cavity is fully utilized, all-dimensional cleaning can be effectively carried out on the oral cavity and the teeth, a user can feel very comfortable when the back teeth are cleaned, the oral cavity and the teeth cannot be hurt, and the back teeth are cleaned conveniently and cleanly.
