[0018] In order to facilitate understanding of the technical solution of the present utility model, the following is a detailed description with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1-3 As shown, a disposable environmentally friendly toothbrush includes a brush head 1, a brush handle 2 and bristles 3. The brush head 1 is made of plastic and is easy to process, avoiding the complicated cutting process of the toothbrush head and saving processing costs. The interior of the brush head 1 is a hollow structure, with a connecting hole 11 provided on one side, and a mounting hole 12 for accommodating the bristles 3 provided on the upper surface of the brush head 1; the brush handle 2 is made of degradable material, and one end is provided with a connecting head 21 located inside the brush head 1, wherein the brush handle 2 is made of bamboo or wood. Since the brush handle 2 occupies more than half of the total volume of the toothbrush product, the disposable toothbrush of this embodiment has a good environmental protection effect.

[0021] The bristles 3 are positioned within the mounting holes 12 and are pressed against the connector 21. A plurality of bristles 3 are positioned within each mounting hole 12. In other words, a plurality of bristles 3 are mounted within each mounting hole 12 using a bristle mounting device, ensuring that the bristles 3 fill the mounting holes 12 and prevent the bristles 3 from falling out during use. Furthermore, the bristles 3 are pressed against the connector 21 to achieve a secure connection between the brush head 1 and the brush handle 2, resulting in a simple structure.

[0022] like Figure 4 As shown, in order to prevent the bristles 3 from falling out of the mounting hole 12, a limiting plate 4 is provided between the inner wall of the mounting hole 12 and the bristles 3. During installation, the limiting plate 4 is installed into the mounting hole 12 together with several bristles 3 to increase the friction between the bristles 3 and the mounting hole 12; or a limiting plate 4 is provided between several bristles 3 in the same mounting hole 12 to squeeze the bristles 3 against the inner wall of the mounting hole 12 to increase the friction between the bristles 3 and the mounting hole 12.

[0023] The connecting head 21 has a recessed portion formed by the bristles 3 being tightly pressed. When installing the bristles 3, the bristles 3 are installed into the mounting hole 12 through a bristle installation device. Since the bristles 3 are relatively thin and the installation pressure is relatively large, the bristles 3 can press out a recessed portion or a local tiny crack on the wooden or bamboo connecting head 21, so that the bristles 3 are tightly pressed on the connecting head 21, preventing the connecting head 21 from detaching from the connecting hole 11 of the brush handle 2.

[0024] Example 2

[0025] like Figure 5-6 As shown, the difference between Example 2 and Example 1 is that a limiting protrusion 22 is provided on the connecting head 21, and a matching limiting groove 13 is provided in the connecting hole 11. The limiting protrusion 22 is located at the inner end of the connecting head 21 and is connected to the body of the brush handle 2, which can improve the strength of the connection between the connecting head 21 and the body of the brush handle 2. In addition, the limiting protrusion 22 cooperates with the limiting groove 13 to limit the position of the brush head 1 and the brush handle 2 when the bristles 3 are installed in the machine, preventing the brush handle 2 from detaching from the brush head 1, and also improving the connection strength between the brush head 1 and the brush handle 2.

[0026] The above are only preferred embodiments of the present invention. The scope of protection of the present invention shall be based on the scope defined by the claims. Several improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall also be regarded as the scope of protection of the present invention.
