[0024] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thoroughly and comprehensively understood.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. In this application, "each" includes one and more than two quantities.

[0026] First embodiment

[0027] Figure 1 is a schematic diagram of a toothbrush head according to the first embodiment. Figure 2 FIG. 1 is a schematic diagram of a toothbrush head according to the first embodiment without illustrating the wrapping layer. Figure 1 and Figure 2 As shown, the toothbrush head of this embodiment includes bristles 11, a hair-implanted head piece 12, a brush head body 13 and a wrapping layer 14.

[0028] The fixed end 111 of the bristle 11 is fixed to the side of the hair implantation head piece 12 facing away from the free end of the bristle 11, and is melted into a whole sheet. The brush head body 13 includes a rod body 131 and a support member 132 located at the front end of the rod body 131. The rod body 131 is connected to the hair implantation head piece 12. The support member 132 is located on the side of the hair implantation head piece 12 facing away from the free end of the bristle 11, and supports the fixed end 111 of the bristle 11. The area of ​​the support member 132 is smaller than the area of ​​the hair implantation head piece 12. The wrapping layer 14 wraps the hair implantation head piece 12 and exposes at least a portion of the support member 132.

[0029] The present application adopts a copper-free hair planting method, passes the bristles 11 through the hair planting holes 123 and melts them into a whole piece, and then supports the support 132 on the brush head body 13 to prevent the bristles 11 from shifting during use, thereby improving the fixing strength of the bristles 11. At the same time, when the wrapping layer 14 is injection molded, the support 132 can serve as a support in the mold to ensure that the wrapping layer material can fully fill the cavity in the ultra-thin space, thereby realizing an ultra-thin toothbrush head by using a copper-free hair planting method, which is more environmentally friendly and can realize the design of the wrapping layer 14. The wrapping layer 14 uses soft glue to improve the comfort of use.

[0030] In this embodiment, the rod body 131 and the support member 132 are integrally formed. The rod body 131 can be used for hand-held or connected to the base of an electric toothbrush. In this embodiment, the support member 132 is arranged at the front end of the rod body 131 and supported in the middle area of ​​the fixed end 111 of the bristles 11, thereby providing uniform supporting force. In actual implementation, the support member 132 can be one or more, and can also be designed into a specific pattern to support different areas or provide different supporting forces for different areas. Since the area of ​​the support member 132 is smaller than the area of ​​the hair-implanted head piece 12, the wrapping layer 14 wraps the hair-implanted head piece 12 while exposing at least a portion of the support member 132, thereby reducing the thickness of the wrapping layer 14 and ensuring that the main area of ​​the toothbrush head in contact with the oral cavity can be wrapped by the wrapping layer 14, reducing the bumps on the teeth and improving the comfort of use.

[0031] In this embodiment, the support member 132 includes a first area 1321 and a second area 1322, the first area 1321 is connected to the rod body 131, and the second area 1322 extends forward from the first area 1321 to the side of the free end of the implanted head piece 12 facing away from the bristles 11, and the thickness of the first area 1321 is greater than the thickness of the second area 1322. In this way, the connection strength between the support member 132 and the rod body 131 can be improved through the first area 1321, and the thickness of the front end of the toothbrush head is reduced through the thinner thickness of the second area 1322, so that the oral cavity can be better cleaned in depth. In this embodiment, the thickness of the second area 1322 is consistent, and the surface of the wrapping layer 14 is flush with the surface of the support member 132, so that the thickness of the wrapping layer 14 can be reduced.

[0032] like Figure 3 As shown, the hair implantation head piece 12 includes a hair implantation portion and a connection portion 124, the hair implantation portion is provided with a hair implantation hole 123 for implanting the bristles 11, and the connection portion 124 is used to connect with the rod body 131. Optionally, the connection portion 124 and the rod body 131 are assembled by a clamping structure, or the rod body 131 is directly wrapped with the connection portion 124 by injection molding to connect with the connection portion 124.

[0033] Combination Figure 3 and Figure 4 The hair implantation head piece 12 includes a metal sheet 121 and a hard plastic layer 122. The metal sheet 121 is provided with a connecting portion 124 and a plurality of through holes 1231. The hard plastic layer 122 wraps the surface of the metal sheet 121 and exposes the side of the free end of the metal sheet 121 facing away from the bristles 11, so that the plurality of through holes 1231 form hair implantation holes 123 for implanting the bristles 11. That is to say, the side wall of the hair implantation head piece 12 corresponding to the hair implantation hole 123 wraps the hard plastic layer 122, and the portion of the metal sheet 121 wrapped by the hard plastic layer 122 serves as the hair implantation portion.

[0034] In this way, by embedding the metal sheet 121 in the hair-implanting head piece 12, the strength of the hair-implanting head piece 12 can be improved. At the same time, the connection part 124 is arranged on the metal sheet 121, which can improve the connection strength between the hair-implanting head piece 12 and the rod body 131. When applied to an electric toothbrush, it can also well transmit the vibration of the motor to obtain a better tooth cleaning effect. In addition, after the hair is implanted and the wrapping layer 14 is formed, the metal sheet 121 is completely wrapped, ensuring the environmental protection of the brush head.

[0035] In actual implementation, combined with Figure 3 and Figure 5 When the hard plastic layer 122 wraps the edge of the metal sheet 121, a retaining rib is formed at the edge of the metal sheet 121, which is convenient for accommodating the fixed end 111 formed when the bristles 11 are melted and ironed, and positioning the fixed end 111. Combined with the supporting function of the support member 132, it can better prevent the bristles from shifting during use.

[0036] Second embodiment

[0037] like Figure 6 As shown, the main difference between this embodiment and the first embodiment is that the second area of ​​the support member includes a thin area and a thick area 2322, and the thickness of the thick area 2322 is greater than that of the thin area. The thick area 2322 is exposed outside the wrapping layer 14 and is flush with the wrapping layer 14, and the thin area is wrapped inside the wrapping layer 14. For example, the thin area extends forward from the first area 2321 to the side of the free end of the hair implantation head piece facing away from the bristles, and the thick area 2322 is a protruding point on the thin area, thereby increasing the support strength of the thin area.

[0038] Based on the above structure, the thickness of the wrapping layer 14 can be reduced, and while ensuring the supporting force of the support member, the exposed area of ​​the support member can be reduced, so that the flexible wrapping area of ​​the toothbrush head is increased, further improving comfort.

[0039] The other structures of the toothbrush head of this embodiment are the same as those of the first embodiment and will not be described in detail.

[0040] The present application also provides a toothbrush, comprising a toothbrush head as described in any of the above embodiments.

[0041] The toothbrush head and toothbrush of the present application, the toothbrush head includes: bristles, a hair-implanted head piece, a brush head body and a wrapping layer; the fixed end of the bristles is fixed to the side of the hair-implanted head piece that faces away from the free end of the bristles, and is in the shape of a whole piece; the brush head body includes a rod body and a support member located at the front end of the rod body, the rod body is connected to the hair-implanted head piece, the support member is located on the side of the hair-implanted head piece that faces away from the free end of the bristles, and supports the fixed end of the bristles, and the area of ​​the support member is smaller than the area of ​​the hair-implanted head piece; the wrapping layer wraps the hair-implanted head piece and exposes at least a portion of the support member. After the bristles are melted into a whole piece, the fixing strength of the bristles is improved by the support of the support member. At the same time, the support member can serve as a support in the mold when the wrapping layer is injection molded, ensuring that the wrapping layer material can be fully filled into the cavity in the ultra-thin space, thereby realizing an ultra-thin toothbrush head by using a copper-free hair-implanting method, which is more environmentally friendly, and can also realize the design of the wrapping layer to improve the comfort of use.

[0042] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
