Description

Toothbrush with trapezoid-face brush head Technical Field The utility model relates to the technical field of toothbrushes, in particular to a toothbrush with a trapezoid-face brush head. Background In the field of oral care, toothbrushes are used as daily cleaning tools, and the rationality of their design directly affects cleaning effectiveness and oral health. Along with the improvement of the degree of importance of oral hygiene, the limitations of the traditional toothbrush in the aspects of cleaning efficiency, comfort level and the like are gradually highlighted, in professional oral care, the problems of dental caries, gingivitis and the like are easily caused by incomplete cleaning of hidden areas such as tooth gaps, gingival sulcus and the like, and the damage of gums and the abrasion of tooth enamel can be caused by excessive hard brushing or unreasonable bristle design, so how to realize omnibearing, efficient and mild oral cleaning becomes the key of toothbrush research and development through innovative brush head structure and bristle layout. The existing toothbrush mainly comprises a brush handle, a brush head and bristles fixed on the brush head, wherein the bristle layout is designed in a planar arrangement mode and is fixed on the plane of the brush head through glue or a bristle planting process. Some powered toothbrushes have improved cleaning by rotating or vibrating, but still have bristle arrangements that are predominantly planar in conventional manner. However, the existing toothbrushes generally have the problem that the cleaning of the tooth surfaces and gaps is difficult to achieve, the oral cavity health maintenance effect is seriously affected, the heights of the bristles of the traditional plane brush head are consistent, and in the tooth brushing process, the teeth surfaces can be cleaned only, the gaps between the teeth are ignored, or the teeth are damaged due to the fact that the teeth are deep in the gaps between the teeth with excessive force. Even if part of toothbrushes are designed with high and low bristles, the staggered arrangement lacks pertinence, and the cleaning requirements of different areas of teeth cannot be accurately matched, so that food residues and dental plaque accumulate at the parts of the teeth slits, gingival sulcus and the like for a long time, which becomes a main cause of causing oral diseases, especially in complex areas such as wisdom teeth, grinding teeth and the like, the problem of incomplete cleaning is more remarkable, and therefore, the toothbrush with the trapezoidal-surface brush head is provided to solve the problem. Disclosure of utility model In order to make up for the defects, the utility model provides a toothbrush with a trapezoid-face brush head, and aims to solve the problems that the heights of bristles of a plane brush head in the prior art are consistent, the cleaning of tooth surfaces and gaps is difficult to achieve, and the oral cavity health maintenance effect is affected.
