[0024] like Figures 1-9 As shown, a toothbrush with a rotatable brush head 1 includes a brush head 1 and a brush handle 2. The brush head 1 and the brush handle 2 are rotatably assembled. The brush head 1 has a connecting head 3 and also includes a pushing member 4 for driving the brush head 1 to rotate relative to the brush handle 2. The pushing member 4 is movably assembled inside the brush handle 2, and one end of the pushing member 4 is rotatably connected to the connecting head 3. When the pushing member 4 is pushed, the pushing member 4 drives the brush head 1 to rotate relative to the brush handle 2.

[0025] The brush handle 2 is provided with a limiting groove 5 at one end of the brush head 1 to limit the rotation angle of the connector 3, thereby limiting the rotation angle of the brush head 1.

[0026] The brush head 1 has a mounting groove 6, and the connector 3 is placed in the mounting groove 6 and slides relative to the mounting groove 6. The limiting groove 5 of the brush handle 2 has a positioning groove 7 on its groove wall. When the pusher 4 pushes the brush head 1 to rotate to the position of the positioning groove 7, the pusher 4 is pushed or pulled so that the end of the pusher 4 connected to the connector 3 is embedded in the positioning groove 7 for positioning, thereby restricting the rotation of the brush head 1.

[0027] There are at least two positioning slots 7, meaning there are at least two positions where the connector 3 can be inserted, thereby restricting the rotation of the brush head 1.

[0028] Preferably, the brush handle 2 includes a first brush handle 21 and a second brush handle 22, the pusher 4 is disposed between the first brush handle 21 and the second brush handle 22, the brush head 1 is rotatably connected to the first brush handle 21, the limiting groove 5 is disposed on the first brush handle 21, and the groove wall of the limiting groove 5 is provided with a positioning groove 7. The first brush handle 21 is also provided with a limiting protrusion 8, and the corresponding pusher 4 is provided with a trajectory groove 9 for accommodating the limiting protrusion 8. The limiting protrusion 8 is disposed in the trajectory groove 9 and can be tracked. Sliding within groove 9; when the pusher 4 is not pushed, the limiting protrusion 8 is in the middle of the track groove 9. Since the track groove 9 is U-shaped, the middle part is exactly the inflection point of the track groove 9. At this time, the limiting protrusion 8 abuts against the inflection point of the track groove 9. When the pusher 4 needs to be pushed, since the limiting protrusion 8 abuts against the inflection point of the track groove 9, a force perpendicular to the length direction of the first brush handle 21 needs to be applied to the pusher 4 so that the limiting protrusion 8 enters the slots on both sides of the inflection point of the track groove 9, and the pusher 4 can be pushed.

[0029] Preferably, the pusher 4 has a locking protrusion 10 on one end face near the first brush handle 21, and the corresponding first brush handle 21 has a locking groove 11 that cooperates with it. When the pusher 4 is not pushed, the locking protrusion 10 is located in the locking groove 11. The first brush handle 21 also has a movable groove 12. When the pusher 4 is pushed, the locking protrusion 10 is dislodged from the locking groove 11 and enters the movable groove 12, and can move within the movable groove 12.

[0030] Preferably, the second brush handle 22 is provided with a limiting baffle 13 at one end near the brush head 1. Correspondingly, the brush head 1 is provided with a track 14 for the limiting baffle 13 to move at the edge near the second brush handle 22. The limiting baffle 13 is located in the track 14. When the brush head 1 rotates relative to the second brush handle 22, the limiting baffle 13 moves along the track 14.

[0031] Preferably, the groove wall of the limiting groove 5 is provided with a notch 15. When the pushing member 4 is not pushed, the connector 3 is located in the notch 15. When the pushing member 4 is pushed, the connector 3 is dislodged from the notch 15 and enters the limiting groove 5.

[0032] Preferably, the mounting groove 6 is provided with a limiting part 16. When the pushing member 4 is not pushed, the connector 3 is located in the limiting part 16. When the pushing member 4 is pushed, the connector 3 is dislodged from the limiting part 16 and enters the mounting groove 6.

[0033] Preferably, the pusher 4 is provided with an anti-slip part 17.

[0034] Working principle: When the pusher 4 is not pushed, the limiting protrusion 8 is in the middle of the track groove 9. Since the track groove 9 is U-shaped, the middle part is exactly the inflection point of the track groove 9. At this time, the limiting protrusion 8 abuts against the inflection point of the track groove 9, the locking protrusion 10 is located in the locking groove 11, the connector 3 is located in the notch 15, the connector 3 is located in the limiting part 16, the length direction of the brush head 1 is consistent with the length direction of the brush handle 2, and the brush head 1 cannot be rotated at this time.

[0035] When the pusher 4 is pushed, since the limiting protrusion 8 abuts against the inflection point of the track groove 9, a force perpendicular to the length direction of the first brush handle 21 needs to be applied to the pusher 4 first, so that the limiting protrusion 8 enters the grooves on both sides of the inflection point of the track groove 9, and then the pusher 4 can be pushed. The pusher 4 moves along the cavity in the brush handle 2 towards the brush head 1. At this time, the locking protrusion 10 disengages from the locking groove 11 and enters the movable groove 12, moving within the movable groove 12. The connector 3 disengages from the notch 15 and enters the limiting groove 5. The connector 3 disengages from the limiting part 16 of the mounting groove 6 and enters the mounting groove 6. Under the push of the pusher 4, the connector 3 moves along the extension direction of the groove wall of the limiting groove 5 and slides within the mounting groove 6 of the brush head 1, thereby driving the brush head 1 to rotate.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Simple modifications and substitutions made by those skilled in the art without departing from the spirit and scope of this utility model are within its protection scope.
