[0002] A toothbrush is an everyday personal care product, primarily used for cleaning teeth and maintaining oral hygiene. It is an essential item in daily life. To maintain the cleaning effect and oral health of a toothbrush, experts recommend replacing it every three months. There are many types and brands of toothbrushes on the market, but none of them can both adjust the angle of the brush head and have barbs at the ends of the bristles. Therefore, inventing a toothbrush that can solve the above problems would be of great significance to people who have difficulty cleaning between their teeth. Utility Model Content
[0003] A toothbrush with a flexible head and barbed bristles is a daily oral hygiene tool. Specifically, it features an adjustable head angle and barbed bristles at the ends to effectively clean food debris from tooth surfaces and between teeth. It primarily consists of a toothbrush head assembly, a handle, and bristles. Figure 1 , Figure 2 As shown.
[0004] The toothbrush described above, with a flexible head and barbed bristles, consists of a toothbrush head assembly mounted on the front end of the handle, and the toothbrush head assembly having several sets of bristles, such as... Figure 1 , Figure 2 As shown.
[0005] The toothbrush head assembly is characterized by having a toothbrush head push-pull bending rod and a toothbrush head connecting rod fixed to the upper and lower sides of the toothbrush head end, respectively. A toothbrush head anti-reverse tooth of a certain length is provided on the upper surface of the tail end of the push-pull bending rod, and a push-pull button is provided on the upper surface of the middle part of the push-pull bending rod. Figure 6 As shown.
[0006] The toothbrush handle is characterized by having a square hole at the front end, with a certain length of anti-reverse teeth on the top surface of the bottom of the square hole, and a push-pull button limiting hole on the upper front surface of the handle, which is perpendicularly connected to the square hole at the front end. Figure 7 , Figure 8 As shown.
[0007] As a further optimization of this solution, the toothbrush head assembly of this utility model has a plurality of bristle mounting holes arrayed on the bottom surface of the toothbrush head. Each bristle mounting hole contains a set of bristles, and each set of bristles consists of a plurality of barbed bristles with barbs at the tail and a plurality of straight bristles. During brushing, the straight bristles clean the tooth surface, while the barbed bristles hook out fibrous food debris from between the teeth. Figure 6 , Figure 9 As shown.
[0008] As a further optimization of this solution, the toothbrush head connecting rod of this utility model is fixedly installed at the lower side of the front end face of the toothbrush handle, and the toothbrush head push-pull bending rod is inserted into the square hole at the end of the handle.

Detailed Implementation
[0021] This utility model relates to a toothbrush with a flexible head and barbed bristles, a daily tool for oral hygiene. Specifically, it is a daily tool with an adjustable head angle and barbed bristles at the ends, designed to clean food debris from the tooth surface and between teeth. The tool mainly consists of a toothbrush head assembly 10, a toothbrush handle 20, and bristles 30. Figure 1 , Figure 2 As shown.
[0022] This utility model features a toothbrush head assembly 10 mounted on the front end of a toothbrush handle 20. The toothbrush head assembly 10 is composed of several sets of bristles 30. Figure 1 , Figure 2 As shown.
[0023] The toothbrush head assembly 10 of this utility model has a toothbrush head push-pull bending rod 13 and a toothbrush head connecting rod 12 fixed to the upper and lower sides of the end of the toothbrush head 11, respectively. A toothbrush head anti-reverse tooth 14 of a certain length is provided on the upper surface of the tail of the toothbrush head push-pull bending rod 13, and a push-pull button 15 is provided on the upper surface of the middle part of the toothbrush head push-pull bending rod 13. Figure 6 As shown.
[0024] The toothbrush handle 20 of this utility model has a square hole 21 at the front end, and a toothbrush handle anti-reverse tooth 22 of a certain length is provided on the top surface of the bottom of the square hole 21. A push-pull button limiting hole 23 is opened on the upper surface of the front part of the toothbrush handle 20, and the push-pull button limiting hole 23 is perpendicularly connected to the square hole 21 at the handle end. Figure 7 , Figure 8 As shown.
[0025] The toothbrush head assembly 10 of this invention has a plurality of bristle mounting holes arranged in an array on the bottom surface of the toothbrush head 11. Each bristle mounting hole contains a set of bristles 30. Each set of bristles 30 is composed of a plurality of barbed bristles 31 with barbs at the tail and a plurality of straight bristles 32. During brushing, the straight bristles 32 clean the tooth surface, while the barbed bristles 31 hook out fibrous food debris from between the teeth. Figure 6 , Figure 9 As shown.
[0026] In this invention, the toothbrush head connecting rod 12 of the toothbrush head assembly 10 is fixedly installed at the lower side of the front end face of the toothbrush handle 20. The toothbrush head push-pull bending rod 13 is inserted into the square hole 21 at the end of the handle. The toothbrush head anti-retraction tooth 14 and the toothbrush handle anti-retraction tooth 22 form an anti-retraction engagement. The push-pull button 15 is embedded in the push-pull button limiting hole 23 at the front of the toothbrush handle 20. Figure 3 , Figure 4 , Figure 5 As shown.
[0027] In this invention, the toothbrush head connecting rod 12 and the toothbrush head push-pull bending rod 13 in the toothbrush head assembly 10 are both made of a spring-loaded and deformable material. During use, when the push-pull button 15 is pushed towards the toothbrush head 11, the toothbrush head push-pull bending rod 13 and the toothbrush head connecting rod 12 will bend inward, and the toothbrush head 11 will bend inward at a certain angle. After releasing the push-pull button 15, the toothbrush head will stop retracting due to the spring-loaded action of the toothbrush head push-pull bending rod 13. 14 engages with the toothbrush handle's anti-retraction tooth 22, keeping the toothbrush head 11 in its current bent position. Pressing down the push-pull button 15 disengages the toothbrush head anti-retraction tooth 14 from the toothbrush handle's anti-retraction tooth 22. Under the rebound action of the toothbrush head connecting rod 12 and the toothbrush head push-pull bending rod 13, the toothbrush head anti-retraction tooth 14 returns to the bottom position of the square hole 21 at the end of the handle, and the toothbrush head 11 returns to the same straight position as the toothbrush handle 20. Figure 3 , Figure 4 , Figure 5 As shown.
[0028] The working process of a toothbrush with a bendable head and barbed bristles is as follows: When the toothbrush is in its normal state, the toothbrush head 11 and the toothbrush handle 20 are in a straight line, and the toothbrush head anti-reverse teeth 14 are located in the square hole 21 at the end of the handle and at the bottom of the hole. When the user needs the toothbrush head 11 to bend inward at a certain angle, the user needs to use their finger to move the push-pull button 15 towards the toothbrush head 11, so that the toothbrush head 11, which is fixedly connected to the toothbrush head push-pull bending rod 13, bends inward. When the degree of bending of the toothbrush head 11 meets the user's requirements, the user releases the push-pull button 15, and the toothbrush head 11 bends inward. The push-pull bending rod 13 of the brush head springs back outward, causing the toothbrush head anti-retraction tooth 14 to engage with the toothbrush handle anti-retraction tooth 22. The toothbrush head 11 and the toothbrush handle 20 form the bending angle required by the user. When the toothbrush head 11 needs to return to its original position, simply press the push-pull button 15 inward. The toothbrush head push-pull bending rod 13, which is located in the square hole 21 at the end of the handle, will then press down. The toothbrush head anti-retraction tooth 14 will disengage from the toothbrush handle anti-retraction tooth 22, and the bent toothbrush head push-pull bending rod 13 will return to a straight state. The toothbrush head 12 will also return to the same straight position as the toothbrush handle 20.
[0029] Because the toothbrush head 11 of the toothbrush head assembly 10 of this utility model has several sets of bristles 30 embedded on its bottom surface, consisting of barbed bristles 31 and several straight bristles 32, when using this utility model to brush teeth, the straight bristles 32 can clean the dirt on the tooth surface, while the barbed bristles 31 with barbs at the tail can go deep into the gaps between teeth and hook out the fibrous food residue in the gaps between teeth, thus achieving effective cleaning of the tooth surface and the gaps between teeth.
