[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figs. 1 to 3 As shown, the present invention provides a brush head including a body 1, a brush plate 2 and multiple sets of bristles 3. The brush plate 2 is disposed on the body 1 and has multiple brush holes 4. The multiple sets of bristles 3 are arranged one-to-one with the multiple brush holes 4. The body 1 and the brush plate 2 are integrally formed by injection molding. The brush plate 2 is provided with a covering 5 and the covering 5 is connected to the body 1.

[0021] In this invention, the brush plate 2 and the body 1 are integrally formed during the molding process, so that the subsequent bristle insertion and coating operations are all carried out on the whole body 1 and the brush plate 2. Thus, during the coating operation, only the whole body needs to be placed into the mold, which improves efficiency and ensures the coating quality.

[0022] In this embodiment, the bristles 3 are inserted into the brush holes 4 and then welded to the brush plate 2. The covering part 5 covers the end of the bristles 3 that is welded to the brush plate 2. The covering part 5 is made by TPE overmolding process.

[0023] After the bristles 3 are inserted into the brush plate 2, the bottom of the bristles 3 will protrude out of the bottom of the brush plate 2, and then the protruding part is melted by hot melting or other conventional process, so that the bristles 3 are bonded to the brush plate 2, realizing the positioning effect of the bristles 3 and the brush plate 2. The welding position is covered by the TPE coating process.

[0024] In the embodiment, the bottom of the brush plate 2 is provided with a glue containing groove 6, and a plurality of positioning columns 7 are arranged in the glue containing groove 6; the covering piece 5 is used to fill the glue containing groove 6 and is connected with the positioning columns 7. Through the arrangement of the glue containing groove 6 and the positioning column 7, when the TPE coating process forms the covering piece 5, the covering piece 5 will have a structure corresponding to the glue containing groove 6 and the positioning column 7, thereby increasing the contact area between the brush plate 2 and the covering piece 5 and ensuring the stability and firmness of the bonding therebetween.

[0025] In the embodiment, the side edge of the brush plate 2 is provided with a plurality of positioning grooves 8, and the covering piece 5 has a plurality of positioning protrusions 9, which are arranged one by one corresponding to the plurality of positioning grooves 8. Through the cooperation of the positioning grooves 8 and the positioning protrusions 9, the contact area between the brush plate 2 and the covering piece 5 is further increased, and the positioning clamping effect is realized, avoiding separation of the two.

[0026] In the embodiment, the plurality of brush holes 4 are divided into straight brush holes 10 and inclined brush holes 11, the straight brush holes 10 are arranged vertically to the brush plate 2, and the angle between the inclined brush holes 11 and the brush plate 2 is θ, 85° < θ < 90°.

[0027] In actual application, the inclined brush holes 11 are distributed on the periphery, so that the bristles 3 inserted into the inclined brush holes 11 also have a certain inclination angle with the brush plate 2, which can make the bristles 3 have better tooth brushing effect in use.

[0028] In the embodiment, the brush plate 2 includes a connecting part 12, a base part 13 and a protruding part 14, the connecting part 12 is connected with the body 1, the base part 13 is connected to one end of the connecting part 12 away from the body 1, and the protruding part 14 is arranged on the top of the base part 13, and the brush hole 4 penetrates through the base part 13 and the protruding part 14; the bottom of the bristle 3 is welded and fixed with the base part 13 after penetrating through the protruding part 14 and the base part 13.

[0029] In actual use, the connecting part 12, the base part 13 and the protruding part 14 are integrally formed. The width of the connecting part 12 is smaller than the width of the body 1, which realizes the connection and fixation between the brush plate 2 and the body 1, and the protruding part 14 is used for accommodating the bristles 3, which has the advantage of improving the strength of the brush plate 2, so that the arrangement of the brush hole 4 will not cause the strength of the brush plate 2 to decrease too much.

[0030] Specifically, the covering member 5 covers the connecting portion 12 base 13, and the protruding portion 14 protrudes out of the covering member 5 by 1 / 3-1 / 2 of the height, effectively avoiding the bristles 3 from being covered by the covering member 5, and ensuring the softness of the bristles 3 and the user's experience.

[0031] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application is disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the technical solution of the present application, and any equivalent embodiment with equivalent changes is equivalent to the above embodiment. Any simple modification, equivalent change and modification of the above embodiment within the scope of the present application are within the scope of the present application.
