[0026] Refer to Figures 1-4 as shown, which is a preferred embodiment provided by the present utility model.

[0027] The assembled bamboo toothbrush includes a toothbrush head 1 and a toothbrush handle 2. At one end where the toothbrush head 1 and the toothbrush handle 2 are close to each other, a first connecting block 3 and a second connecting tube 4 are respectively installed. The outer wall surface of the first connecting block 3 is in contact with the inner wall surface of the second connecting tube 4. A first connecting groove 5 is formed on the first connecting block 3. The first connecting groove 5 is annularly formed on the outer curved surface of the first connecting block 3. A plurality of connecting holes 6 are formed on the second connecting tube 4. A ball 7 is slidably fitted in each of the plurality of connecting holes 6. A spring 8 is sleeved on the outer curved surface of the second connecting tube 4. A push ring 9 is arranged outside the spring 8. The push ring 9 is slidably connected to the second connecting tube 4. A limiting ring 10 is installed on the inner wall surface of the push ring 9. The limiting ring 10 corresponds to the position of the first connecting groove 5.

[0028] By moving the toothbrush head 1 towards the toothbrush handle 2 and moving the push ring 9 towards the toothbrush handle 2, the limiting ring 10 is driven to move synchronously, thereby releasing the limiting state of the limiting ring 10 on the plurality of balls 7, so that the first connecting block 3 can move into the second connecting tube 4. Then, the push ring 9 is released, and the spring 8 resets to push the limiting ring 10 to move towards the toothbrush head 1 until the limiting ring 10 contacts the plurality of balls 7, thereby restricting the balls 7 between the first connecting groove 5 and the plurality of connecting holes 6, thus completing the installation of the toothbrush head 1 and the toothbrush handle 2. When it is necessary to disassemble the toothbrush head 1 from the toothbrush handle 2, only need to move the push ring 9 towards the toothbrush handle 2 and control the toothbrush head 1 to move in the direction opposite to the toothbrush handle 2, then the toothbrush head 1 can be disassembled from the toothbrush handle 2. The installation and disassembly of the toothbrush head 1 and the toothbrush handle 2 in this toothbrush are simple and fast, which is convenient to meet the need of frequent replacement of the toothbrush head 1 under long-term use. And both the toothbrush head 1 and the toothbrush handle 2 are made of bamboo products, which is energy-saving and environment-friendly.

[0029] Specifically, in this embodiment, an installation groove 11 is formed at one end of the toothbrush handle 2 close to the toothbrush head 1. The first connecting block 3, the second connecting tube 4 and the push ring 9 are all located inside the installation groove 11, so that when the toothbrush head 1 needs to be movably installed on the toothbrush handle 2, the connection between the toothbrush head 1 and the toothbrush handle 2 can be completed through the installation groove 11, thus avoiding the need for additional installation space when installing the toothbrush head 1 and the toothbrush handle 2 and reducing the use performance of the toothbrush.

[0030] Specifically, in this embodiment, a third connecting ring 13 is installed between the first connecting block 3 and the second connecting tube 4. A second connecting groove 14 is formed on the first connecting block 3. The third connecting ring 13 is adapted to the second connecting groove 14, so that the toothbrush handle 2 can be inserted into the second connecting groove 14 through the third connecting ring 13, thereby increasing the connection area between the toothbrush head 1 and the toothbrush handle 2 and further improving the connection stability between the two.

[0031] Specifically, in this embodiment, the outer diameter of the push ring 9 is smaller than the size of the installation groove 11, and the inner diameter of the limit ring 10 is adapted to the outer diameter of the second connecting pipe 4, so that the push ring 9 can move normally on the brush handle 2 without being restricted, thereby driving the limit ring 10 to move on the second connecting pipe 4, and further realizing the locking between the brush head 1 and the brush handle 2.

[0032] Specifically, in this embodiment, the wall thickness of the limit ring 10 is greater than the wall thickness of the spring 8, and the inner wall diameter of the limit ring 10 is smaller than the inner diameter of the spring 8, so that the limit ring 10 moves towards the brush handle 2 direction, thereby driving the spring 8 to be compressed. When the spring 8 is compressed and reset, it can drive the limit ring 10 to move towards the brush head 1 direction, thus facilitating the installation and disassembly between the brush head 1 and the brush handle 2.

[0033] Specifically, in this embodiment, several connecting holes 6 are all spherical holes, and the size of the opening at one end of several connecting holes 6 close to the first connecting pipe 3 is smaller than the diameter of the ball 7, so that the ball 7 can move in the connecting hole 6 and part of it is stuck in the first connecting groove 5, rather than completely falling into the first connecting groove 5 from the connecting hole 6, thereby ensuring the stable connection between the first connecting pipe 3 and the second connecting pipe 4.

[0034] Specifically, in this embodiment, a fourth connecting ring 15 is installed at one end of the second connecting pipe 4 close to the brush head 1. The fourth connecting ring 15 is adapted to the opening formed between the push ring 9 and the limit ring 10. When the spring 8 is reset, it drives the push ring 9 to move towards the brush head 1 direction. During the movement, the push ring 9 and the limit ring 10 come into contact with the fourth connecting ring 15 and are blocked by the fourth connecting ring 15, so that the push ring 9 is always slidably connected to the second connecting pipe 4, thereby avoiding the situation that the push ring 9 and the brush head 1 fall off the toothbrush when the brush head 1 and the brush handle 2 are in a non-connected state.

[0035] Specifically, in this embodiment, a pull rod 16 is installed at one end of the push ring 9 far from the brush head 1. The length of the pull rod 16 is smaller than the length from the end of the brush handle 2 far from the brush head 1 to the push ring 9, so that when assembling the toothbrush, the pull rod 16 can be pulled towards the end far from the brush head 1, thereby driving the push ring 9 to move, and further facilitating the connection between the brush head 1 and the brush handle 2.

[0036] Specifically, in this embodiment, a prolongation shaft 17 is rotatably connected to one end of the pull rod 16 far from the brush head 1. The end of the prolongation shaft 17 far from the pull rod 16 is arc-shaped and fits the shape of the back of the brush handle 2, so that the length of the pull rod 16 can be extended through the prolongation shaft 17, facilitating the user to drive the pull rod 16 to move by pulling the prolongation shaft 17.

[0037] Specifically, in this embodiment, an L-shaped notch 18 is formed at one end of the brush handle 2 away from the brush head 1. The L-shaped notch 18 communicates with the installation groove 11, and both the pull rod 16 and the extension shaft 17 are located within the L-shaped notch 18. After the toothbrush is assembled, the extension shaft 17 can be rotated, and then the extension shaft 17 and the pull rod 16 are pushed into the L-shaped notch 18, thereby reducing the occupied space of the pull rod 16 and the extension shaft 17 and improving the practicality of the toothbrush.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
