[0031] Embodiment:

[0032] As Figures 1-4 , the toothbrush head of the application comprises a brush head body 100, a bristle 200 and a soft rubber coating layer 300, the brush head body 100 comprises a brush head 101 and a brush handle 102 integrally formed with the brush head 101, the brush head 101 is provided with a bristle part 1011, the bristle 200 is arranged on the bristle part 1011, and the soft rubber coating layer 300 covers the brush head 101 to the edge of the bristle part 1011. The end surface of the soft rubber coating layer 300 is located on the same horizontal plane as the end surface of the bristle part 1011. Through the above structural design, the application comprises the brush head body 100 integrally formed by the brush head 101 and the brush handle 102, the bristle 200 and the soft rubber coating layer 300, which has few parts and simple production and assembly process. The soft rubber coating layer 300 covers the brush head to the edge of the bristle part 1011, and the end surface of the soft rubber coating layer 300 is located on the same horizontal plane as the end surface of the bristle part 1011, so that there is no gap or corner on the surface of the brush head 101, which is convenient for cleaning and not easy to breed bacteria, thereby reducing the risk of oral diseases.

[0033] Specifically, there is a height difference between the outer surface of the brush head 101 and the outer surface of the brush handle 102, that is, the height of the outer surface of the brush head 101 is lower than the height of the outer surface of the brush handle 102. After the soft rubber coating layer 300 covers the brush head 101, the outer surface of the soft rubber coating layer smoothly transitions to the outer surface of the brush handle, thereby ensuring the quality and comfort of the product.

[0034] Specifically, the bristle part 1011 is provided with a plurality of bristle implantation holes 1012, and each bristle implantation hole 1012 is provided with a plurality of bristle bundles 201. The bristle bundles 201 are implanted into the bristle implantation holes 1012 through a copper-free bristle implantation technology, so that the combination of the bristle bundles 201 and the bristle part 1011 is more firm and not easy to fall off. Since there is no metal part, rusting is not easy to occur, thereby prolonging the service life of the brush head.

[0035] Specifically, the plurality of bristle bundles 201 have a height difference, and the height difference is in the range of 0.2mm-2mm. The height difference of the plurality of bristle bundles 201 has a bristle curved surface with an arc. The bristle curved surface cooperates with the curved surface shape of the teeth, so that the bristle bundles 201 can better fit the teeth and improve the cleaning effect.

[0036] The embodiment is prepared by the following steps:

[0037] S1, a horizontal injection molding machine is used to injection mold the brush head body 100, and the brush head body 100 is made of ABS material;

[0038] S2, implanting the bristles 200 on the brush head 101 by a copper-free bristle implanting technology; the bristles 101 adopt DuPont 612 or sharpened wire PBT material.

[0039] S3, forming the soft glue covering layer 300 by a vertical glue injection molding machine; the soft glue covering layer 300 adopts TPE or TPR or food-grade silica gel.

[0040] In summary, the utility model discloses the structure design above, solve the deficiency in the prior art, with reasonable structure, safe and sanitary etc.

[0041] The above content is further detailed description of the utility model made in combination with specific preferred embodiments, and the specific implementation of the utility model cannot be limited to these descriptions. For ordinary skilled persons in the technical field to which the utility model belongs, on the premise of not departing from the concept of the utility model, a plurality of simple deductions or substitutions can be made, and all should be regarded as the protection scope of the utility model.
