Description

Technical Field

[0001] The utility model relates to the technical field of toothbrushes, and particularly relates to a toothbrush. Background Art

[0002] Generally speaking, a toothbrush is used to wipe teeth by applying a direct force to the user to remove food residues adhering to the teeth after eating, thereby preventing dental plaque from adhering to the tooth surface.

[0003] Most of the existing toothbrushes are of an integral fixed structure. When brushing teeth, the angle of the toothbrush can only be adjusted by the wrist, which brings inconvenience to the brushing operation. When a user uses an existing toothbrush to brush teeth, the crown top, the inner and outer sides of the crown, the interdental spaces between teeth, and the inner and outer gingival crevices in the oral cavity and other brushing areas need to be cleaned by brushing. However, due to the narrow space in the oral cavity, it is difficult for the user to change the brushing posture or angle of the brush handle by hand, and thus it is difficult to change the brushing angle, brushing orientation or brushing posture of the brush head, so it is difficult to meet the all-round brushing angle requirements, resulting in incomplete cleaning of some brushing areas in the oral cavity, such as dirt in the gingival crevices near the inner part of the oral cavity that cannot be cleaned.
