TOOTHBRUSH
Document Type and Number:
WIPO Patent Application WO/2023/020001
Kind Code:
A1
Abstract:
A toothbrush, comprising a brush handle (1); a connecting seat (2), one end of which is hinged to the brush handle (1); a brush head (3), which is connected to the other end of the connecting seat (2); and an elastic member (4), which is mounted on the connecting seat (2), one end of the elastic member being connected to the brush handle (1), and the other end of the elastic member (4) being connected to the connecting seat (2). A limiting structure is provided between the connecting seat (2) and the brush handle (1). During teeth brushing, when an external force is applied to the brush head (3), the brush head (3) swings within a certain range on the brush handle (1) by means of the connecting seat (2); and when the external force applied to the brush head (3) disappears, the brush head (3) and the connecting seat (2) may be restored to an initial position state under an elastic pulling action of the elastic member (4), so as to repeat a subsequent teeth brushing operation. Therefore, the brush head (3) and the brush handle (1) are connected by means of the connecting seat (2) and the elastic member, so that the brush head (3) has a certain elastic deformation capability, which helps to improve the comfort of teeth brushing. In addition, the swing angle of the brush head (3) can be limited by means of a limiting structure, preventing the swing angle of the brush head (3) from being excessively large.
