Description

Rotatable brush head type tooth-protecting toothbrush

Technical Field

The utility model belongs to the field of tooth cleaning appliances, in particular to a rotatable brush head type tooth-protecting toothbrush.

Background

Current toothbrushes, whether unpowered or powered, are essentially identical in their form, namely: the structures of the brush handle, the brush head and the bristles, and the brush handle and the brush head are basically vertical toothbrushes (the brush head extends along the brush handle, and the bristles are attached to the brush head, or the brush head and the brush handle are integrated and are in a relatively straight shape). The difference mainly lies in the form and the material of the brush hair, and the difference of the material mainly lies in nylon, polypropylene, nano-wire or pet composite material and the like; the shape difference mainly includes single-head toothbrush, three-head toothbrush, single-side bristle toothbrush, double-side bristles on the front and back sides, and the like. However, these different toothbrushes are used in a manner that their brushing postures are basically the same, and basically, they are moved laterally from side to side (lateral brushing method).

Scientific studies indicate that when brushing front teeth (the outer side surface after occlusion of teeth), a vertical reciprocating mode (repeated from upper gingiva to lower gingiva) (pasteur tooth brushing method) is suitable, but in practice, due to the structure of the toothbrush, the posture of holding the toothbrush by hand and the physiological structure of arms, the vertical reciprocating mode is not easy to use, while the horizontal tooth brushing mode is generally adopted and mostly adopted, which causes damage to the tooth surface during tooth brushing, serious damage to enamel, dentin, gingiva and periodontal, and is not beneficial to cleaning of front teeth crevice (not beneficial to removing plaque near gingival margin and in gingival sulcus).

However, if the design of the brush head is entirely transverse, i.e. the head is perpendicular to the handle (horizontal toothbrush) (similar to a rake configuration), such a configuration facilitates the swinging up and down of the arm during brushing. Although the horizontal toothbrush can effectively reduce the damage to the teeth and can effectively clean the vicinity of the gingival margin and the gingival sulcus, the horizontal toothbrush is very inconvenient to clean the cut surface, the side surface and the inner part of the teeth, the arms are not easy to swing, and the horizontal toothbrush is difficult to reach the inner side of the oral cavity; if the horizontal toothbrush and the vertical toothbrush are used respectively, the consumption of toothpaste is increased, and the toothpaste occupies space and wastes time and labor in use.

Researches have proved that the pasteurization tooth brushing method is a more scientific and effective tooth brushing mode, and one core action of the pasteurization tooth brushing method is to adopt a reciprocating tooth brushing posture from upper gum to lower gum when the outer surface of teeth is brushed, so that the damage to the teeth caused by tooth brushing can be effectively avoided, and the cleaning effect of the vicinity of the gingival margin and the gingival sulcus can be improved. In real life, most of the people adopt a left-right horizontal type tooth brushing mode. In addition, when the fixed horizontal toothbrush is used for cleaning the cut surfaces, the side surfaces and the inner surfaces of teeth, the toothbrush is not easy to swing, the inner side of the oral cavity is difficult to reach, and great limitation exists in the use.
