Referring further to fig. 1 and 7, the outer annular wall of the deadline ring 30 has a deadline scale 31 for indicating a date, and the deadline scale 31 may include 12 scale marks, which may be 1 to 12 numeral marks, each of which indicates a month corresponding thereto, and the numeral marks may be arabic numerals, roman numerals, english letters, chinese characters, etc., including but not limited thereto. The term ring 30 is provided with a plurality of limiting grooves 301 on the inner wall, and the limiting grooves 301 are arranged along the circumference of the term ring 30 at intervals. Correspondingly, 12 limiting grooves 301 are formed, and one limiting groove 301 corresponds to one scale mark.

The elastic arm 22 can be switched between being clamped in the limiting groove 301 and elastically abutting against the inner annular wall of the limit ring 30 through elastic deformation. The deadline ring 30 can rotate relative to the limiting member 20, so that the elastic arm 22 is switched between being clamped in the limiting groove 301 and elastically abutting against the inner annular wall of the deadline ring 30, and the limiting groove 301 enables the deadline ring 30 to form a plurality of clamping points in the rotating process, so as to improve the operation hand feeling.

Referring to fig. 8, the elastic arm 22 has a limit state clamped in the limit groove 301 and an over state elastically abutting against the inner annular wall of the term ring 30, and the term ring 30 can rotate to elastically deform the elastic arm 22 and switch from the limit state to the over state, or rotate to reset the elastic arm 22 and switch from the over state to the limit state. The term scale 31 can correspond to the start mark 11 when the resilient arm 22 is in the limiting state, it being understood that when the resilient arm 22 is in the limiting state, the mark can point to a certain number of the term scale 31 to indicate the starting month. The respective limiting grooves 301 thus form a click point during rotation of the timing ring 30.

In one embodiment, the timing ring 30 can rotate in a forward direction, and the resilient arms 22 can restrict the timing ring 30 from rotating in a reverse direction when in the limit position, so as to achieve unidirectional rotation of the timing ring 30. Referring to fig. 6, the elastic arm 22 is in the shape of a strip, wherein the elastic arm can be in the shape of a straight strip or a curved strip. The elastic arm 22 has a connection end 221 connected to the fixed body 21 and an extension end 222 spaced from the fixed body 21, a connection line between the extension end 222 and the circle center corresponding to the term ring 30 and a connection line between the extension end 222 and the connection end 221 form an included angle, and the extension end 222 can abut against the bottom of the limiting groove 301. It will be appreciated that the resilient arms 22 extend generally helically outwardly relative to the fixed body 21 so that their outwardly facing side walls can form a guiding ramp. Wherein, the elastic arm 22 and the limit ring 30 are on the same plane to enhance the stability of the two abutting. One or more elastic arms 22 may be provided, and in this embodiment, two elastic arms 22 are provided to enhance the locking effect. The two elastic arms 22 are preferably arranged in a central symmetry manner, so that the time limit ring 30 is uniformly stressed and can achieve the same positioning effect, and when the elastic arms 22 are in a limiting state, the two elastic arms 22 are respectively clamped in one limiting groove 301.

The elastic arm 22 is not elastically deformed when in the position-limiting state, and at this time, the elastic arm 22 and the extending end 222 thereof are located in the position-limiting groove 301, and at this time, the extending end 222 can be suspended to reduce noise. In the present embodiment, the elastic arm 22 is elastically deformed, and at this time, the elastic arm 22 can elastically abut against the edge of the limiting groove 301, preferably the groove bottom of the limiting groove 301, so as to generate sound during the rotation process, thereby improving the operation feeling of the user.

When the user rotates the term ring 30 in the forward direction, the inner annular wall of the term ring 30 applies a force to the guiding inclined surface, so that the elastic arms 22 are elastically deformed inward, that is, the extending end 222 moves toward the fixing body 21, so that the extending end 222 moves from the inside of the limit groove 301 to elastically abut against the inner annular wall of the term ring 30 during the rotation of the term ring 30, and when the term ring 30 wants to rotate in the reverse direction, the tip formed by the extending end 222 abuts against the groove wall of the limit groove 301, so that the term ring 30 cannot rotate.

The limit ring 30 can rotate forward relative to the limiting member 20, and the elastic arm 22 is continuously switched between the limiting state and the transition state during the forward rotation, when the elastic arm 22 is in the limiting state, the limit scale 31 corresponds to the start mark 11, and at this time, the elastic arm 22 can limit the limit ring 30 to rotate reversely. When a user starts to use the toothbrush, the current date on the time limit scale 31 corresponds to the starting mark 11 by rotating the time limit ring 30, so that the use starting time of the user can be marked, after the user uses the toothbrush for a period of time, the user can calculate the use duration of the toothbrush by subtracting the marked starting time from the current time, and the use duration can be replaced when the calculated use duration reaches three months, so that the user is prevented from forgetting the use duration of the toothbrush, and the user can be ensured to replace the toothbrush regularly.

Due to the limiting effect of the elastic arm 22, the limit ring 30 can only realize one-way rotation, and the possibility of misoperation of personnel is reduced. Preferably, the rotation direction of the term ring 30 is opposite to the arrangement direction of the numbers from small to large. For example, the time limit ring 30 can only rotate clockwise, and the number marks from 1 to 12 are arranged from small to large in a counterclockwise manner, so that even if the time limit ring 30 is rotated by misoperation of personnel, the number pointed by the mark is a smaller number, namely, the starting date is advanced, when the service life calculated by the user reaches three months, the user only uses two months actually, the user can replace the service life in advance, and the condition that the service life is not replaced after more than three months due to misoperation of personnel is avoided.

Referring to fig. 5 and 8, to further improve the operation feeling of the user, the limiting member 20 further includes a protrusion 23, and the protrusion 23 is connected to one side of the elastic arm 22 close to the term ring 30 and can abut against the inner annular wall of the term ring 30 when the elastic arm 22 is in the limiting state. It can be understood that when the elastic arm 22 is elastically restored until the extension end 222 is caught at the bottom of the stopper groove 301, the protrusion 23 is also caught at the inner circumferential wall of the term ring 30, thereby increasing the sound when the term ring 30 reaches a certain point, so that the user's operational feeling is stronger.

In another embodiment, the extending direction of the resilient arm 22 is not limited, and the opposite side of the extending end 222 has a guiding surface 2221, the guiding surface 2221 forms an acute angle with the bottom surface of the limit ring 301 when the limit ring 30 is in the limit state, at this time, the limit ring 30 can make the guiding surface 2221 of the resilient arm 22 abut against the corner where the groove wall of the limit ring 301 meets the inner annular wall of the limit ring 30 through forward rotation, at this time, the limit ring 30 continues to rotate forward, and the corner can apply pressure to the guiding surface 2221, so that the resilient arm 22 is resiliently deformed and is switched to the transition state.

In another embodiment, referring to fig. 9, the extending end 222 of the elastic arm 22 has two guiding surfaces 2221, the two guiding surfaces 2221 are respectively disposed on the forward side and the reverse side of the elastic arm 22, and form an acute angle with the bottom surface of the limit groove 301 when the limit ring 30 is in the limit state, at this time, no matter the limit ring 30 rotates forward or reversely, one of the guiding surfaces 2221 of the elastic arm 22 can be abutted against the connecting corner between the groove wall of the limit groove 301 and the inner annular wall of the limit ring 30, and at this time, the limit ring 30 continues to rotate forward or reversely, and the corner can apply pressure to the guiding surface 2221, so that the elastic arm 22 elastically deforms and switches to the transition state. This achieves a bi-directional rotation of the life ring 30.

Referring to fig. 8, in the present embodiment, the central axis of the term ring 30 extends in the same direction as the handle, so as to better conform to the usage habit of the user. The term ring 30 is adapted to the mounting groove 101, that is, in the embodiment, referring to fig. 1, the term ring 30 and the limiting member 20 are disposed at an end of the brush handle close to the brush head, in another embodiment, referring to fig. 2, the term ring 30 and the limiting member 20 are disposed at a middle portion of the brush handle, and in still another embodiment, referring to fig. 3, the term ring 30 and the limiting member 20 can be disposed at an end of the brush handle far from the brush head.

In order to make the date marked more accurate, the term ring 30 is provided in plurality, and the central axes of the plurality of term rings 30 coincide. The plurality of time limit rings 30 may be connected to a limiting member 20, or a plurality of limiting members 20 may be correspondingly disposed, and one time limit ring 30 is connected to one limiting member 20.
