WIPO Patent Application WO/2021/238620
Kind Code:
A1
Abstract:
The present application provides a toothbrush, comprising a toothbrush body (10), a limiting member (20), and a service period indicating ring (30). The toothbrush body (10) has a start mark; the service period indicating ring (30) is sleeved outside the limiting member (20) and can rotate in a forward direction with respect to the limiting member (20), an outer ring wall of the service period indicating ring (30) has a service period scale representing a date, and a plurality of limiting grooves (301) arranged at intervals along a circumferential direction of the service period indicating ring (30) are formed in an inner ring wall of the service period indicating ring (30); the limiting member (20) comprises a fixed body (21) connected to the toothbrush body (10), and at least one elastic arm (22) connected to a side wall of the fixed body (21) and extending outwards; the elastic arm (22) can be switched between a state of being engaged into the corresponding limiting groove (301) and a state of being elastically abutted against the inner ring wall of the service period indicating ring (30) by means of elastic deformation in the rotating process of the service period indicating ring (30). When a user starts to use the toothbrush, the current date on the service period scale can be made to correspond to the start mark by rotating the service period indicating ring (30); when a calculated usage duration reaches three months, the toothbrush can be replaced, thereby preventing the user from forgetting the usage duration of the toothbrush.
