[0026] 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.

[0027] 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.

[0028] First embodiment

[0029] like Figures 1 to 3 As shown, the toothbrush head with ribs of this embodiment includes bristles 11, a brush head body 12 and a wrapping layer 13. The brush head body 12 includes a hair-planting hole 121 and a rib 122. The bristles 11 are inserted into the hair-planting hole 121, and the fixed end 111 of the bristles 11 is fixed to the side of the free end 112 of the brush head body 12 facing away from the bristles 11. The ribs 122 are formed on the side of the free end 112 of the brush head body 12 facing away from the bristles 11. The ribs 122 are located between the hair-planting holes 121 and at least a portion of the ribs 122 are connected to each other. The wrapping layer 13 at least wraps the side of the free end 112 of the brush head body 12 facing away from the bristles 11.

[0030] The technical solution of the present application is to set ribs 122 on the brush head body 12, which can enhance the strength of the toothbrush head. After the brush head body 12 is thinned, the strength of the brush head body 12 can still be guaranteed. At the same time, when the bristles 11 are melted, the ribs 122 and the fixed ends 111 of the bristles 11 form a mutually combined structure during melting, which can enhance the pull-off strength of the bristles 11, which is conducive to the thinning design of the toothbrush head, and is particularly suitable for the thinning design of copper-free bristle toothbrushes.

[0031] In one embodiment, a groove is provided on the side of the brush head body 12 facing away from the free end 112 of the bristles 11, and the groove is used to receive the fixed end 111 formed after the bristles 11 are melted and scalded, and the hair planting hole 121 and the rib 122 are located in the groove. Figure 1 and Figure 4 , a retaining rib 123 is provided at the edge of the sink, the implanting hole 121 and the rib 122 are located in the sink, and the rib 122 is connected or not connected to the retaining rib 123. In this embodiment, the top surface of the rib 122 is flush with the top surface of the retaining rib 123, that is, the height of the rib 122 is equal to the depth of the sink.

[0032] In this embodiment, the ribs 122 are connected to each other to form a honeycomb structure, which has a good strength enhancement effect. In actual implementation, the ribs 122 can also be connected to each other to form an irregular structure.

[0033] In this embodiment, the ribs 122 divide each hair implantation hole 121 into a separate area, and in each area divided by the ribs 122, the fixed end 111 of the bristle 11 is melted into a whole piece. Figure 2 As shown, the end of the bristle 11 in each implanting hole 121 is melted into an area separately and combined with the surrounding ribs 122 to improve the pull-off strength of the bristle 11.

[0034] In one embodiment, the wrapping layer 13 is a soft wrapping layer, and the ribs 122 are at least partially higher than the fixed ends 111 of the bristles 11. When the bristles 11 are melted, the top surface of the fixed ends 111 of the bristles 11 formed after melting is lower than or equal to the top surface of the ribs 122, that is, after the bristles 11 are melted, the fixed ends of the bristles 11 are not covered with the ribs 122, so that at least a portion of the ribs 122 are exposed. In this way, when the soft wrapping layer 13 is formed, the wrapping layer 13 can be well combined with the ribs 122, solving the problem of insufficient bonding between the soft wrapping layer 13 and the fixed ends 111 of the bristles 11. In this way, the strength of the toothbrush head can be enhanced, while reducing the gap between the parts and improving the vibration transmission of the sonic motor.

[0035] In actual implementation, the height of the rib 122 may also be greater than the depth of the groove, and may also be combined with the wrapping layer 13 .

[0036] Second embodiment

[0037] like Figure 5 As shown, the difference between this embodiment and the first embodiment is that the ribs 322 divide the adjacent multiple hair implantation holes into one area, and the ribs 322 are interconnected to form an irregular structure.

[0038] A groove is arranged on one side of the free end of the brush head body facing away from the bristles, and a retaining rib 323 is arranged at the edge of the groove. The hair planting holes and the ribs 322 are located in the groove, and the ribs 322 are connected or not connected to the retaining ribs 323.

[0039] like Figure 6 As shown, in each area divided by the ribs 322, the fixed ends 312 of the bristles are melted into a whole piece, so that in each area divided by the ribs, the fixed ends 312 of the bristles in adjacent hair-planting holes are connected to each other and form a combined structure with the surrounding ribs 322, further improving the pull-off strength of the bristles. At the same time, the design of the ribs 322 can be simplified and the strength of the brush head body can be guaranteed.

[0040] It can be understood that according to the different requirements for the pull-off strength of the bristles in different areas, in a toothbrush head, the ribs 322 can also divide a part of the hair transplantation holes into a separate area, or divide multiple adjacent hair transplantation holes in a part of the hair transplantation holes into a area.

[0041] Third embodiment

[0042] like Figure 7 As shown, the difference between this embodiment and the first embodiment or the second embodiment is that the height of the rib is lower than the depth of the groove. After the bristles are melted, the fixed end 212 covers the rib, exposing the retaining rib 123 at the edge of the groove, which can enhance the bonding force between the rib and the fixed end 212 of the bristles, further improving the pull-off strength of the bristles.

[0043] It can be understood that, according to different requirements for the bonding strength between the fixed end and the wrapping layer in different areas, in a toothbrush head, a portion of the fixed ends are the same height as the ribs, and a portion of the fixed ends are lower than the ribs.

[0044] The present application also provides a toothbrush, comprising a toothbrush head with ribs as described in any of the above embodiments.

[0045] The toothbrush head and toothbrush with ribs of the present application, the toothbrush head includes bristles, a brush head body and a wrapping layer; the brush head body includes hair-planting holes and ribs; the bristles are inserted into the hair-planting holes, and the fixed ends of the bristles are fixed to the side of the free end of the brush head body facing away from the bristles; the ribs are formed on the side of the free end of the brush head body facing away from the bristles, the ribs are located between the hair-planting holes and at least a part of the ribs are interconnected; the wrapping layer at least wraps the side of the free end of the brush head body facing away from the bristles. The ribs are arranged on the brush head body of the present application, which can enhance the strength of the toothbrush head and enhance the pull-off strength of the bristles, which is conducive to the thinning design of the toothbrush head.

[0046] 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.
