[0001] This application relates to the technical field of toothbrushes, and particularly to a toothbrush head. Background Art

[0002] Toothbrushes are the main tools for people to maintain oral hygiene and are essential items in daily life. There are many types of toothbrushes. In the market, they can be divided into ordinary manual toothbrushes, electric toothbrushes, and sonic toothbrushes according to the driving method; they can be divided into single-head toothbrushes, interdental brushes, and tail-shaped toothbrushes according to the contact surface; according to the shape and structure, toothbrushes can be divided into linear toothbrushes and T-shaped toothbrushes; according to the bristles, toothbrushes can be divided into flat bristles, wavy bristles, and full-contact bristles; products are emerging in an endless stream and are dazzling.

[0003] Among them, the structure of the toothbrush head is particularly important for the comfort and hygienic effect during oral cleaning. The bristle structure of the existing toothbrush heads is simple. In order to improve the cleaning effect, some toothbrush heads have an arc-shaped surface or multiple arc-shaped surfaces with the same height on the head surface. When deeply cleaning the posterior molars on both sides, it is difficult for the arc surface of the toothbrush head to fit the teeth in this area, and the comfort and cleaning effect still need to be improved. In addition, the sizes of the head holes of the existing toothbrush heads are the same, making it difficult to reasonably and effectively utilize the head space, and the number of toothbrush heads that can be set still needs to be improved, which affects the user experience. Summary of the Utility Model

[0004] The purpose of the present utility model is to solve the above technical problems and provide a toothbrush head. The bristles of the toothbrush head of this application are adapted to the teeth in various regions of the oral cavity, with hair implantation in different areas, precise and efficient cleaning, and high comfort.

[0005] To achieve the above purpose, the technical solution of the present utility model is as follows:

[0006] A toothbrush head includes a head body and a connecting handle. The head body is provided with a plurality of mounting holes and is fixed with a bristle group composed of toothbrush heads.

[0019] The embodiment of the present application provides a toothbrush head, which is used to solve the problems that the bristle structure of the existing toothbrush head is simple and it is difficult to adapt to the teeth in various areas of the oral cavity, resulting in poor cleanliness and comfort.

[0020] In order to make the invention purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0021] Please refer to Figures 1 to 4 , the embodiment of the present application provides a toothbrush head, including a brush head body 100 and a connecting handle 200. The brush head body 100 is provided with a plurality of mounting holes 110 and is fixed with a bristle group 300 composed of brush heads. The end face of the bristle group 300 includes a first arc surface 310, a connecting arc surface 320 and a second arc surface 330. The first arc surface 310 is located at one end away from the connecting handle 200; the starting end height of the first arc surface 310 is higher than the two end heights of the connecting arc surface 320 and the second arc surface 330. The arc surface depth D1 formed between the first arc surface 310 and the connecting arc surface 320 is smaller than the arc surface depth D2 formed between the second arc surface 330 and the connecting arc surface 320; the mounting holes 110 include a first mounting hole 111 covering the brush head body 100 and a second mounting hole 112 surrounding the first mounting hole 111, and the size of the first mounting hole 111 is smaller than that of the second mounting hole 112.

[0022] Specifically, the mounting holes 110 provided on the brush head body 100 are used to fix the bristles. The upper end surfaces of the formed bristle groups 300 are respectively the first arc surface 310, the connecting arc surface 320 and the second arc surface 330 from the end far away from the connecting handle 200; the first arc surface 310 and the second arc surface 330 are concave arc surfaces, and the connecting arc surface 320 is a convex arc surface. Thus, the entire end surface of the brush head is an arc surface. When brushing teeth, the first arc surface 310 and the second arc surface 330 can be more closely attached to the tooth surface for cleaning, and the connecting arc surface 320 can clean the tooth gaps between teeth; among them, the starting end height of the first arc surface 310 is higher than the two end heights of the connecting arc surface 320 and the second arc surface 330, so that the starting end of the upper end of the brush head end surface is the highest end. When deeply cleaning the posterior molar area on both sides of the oral cavity, the starting end of the first arc surface 310 can clean the inner side of the posterior molar, with a better cleaning effect. At the same time, due to the different arc depths formed between the first arc surface 310, the second arc surface 330 and the connecting arc surface 320, that is, the arc depth D1 of the first arc surface 310 is less than the arc depth D2 of the second arc surface 330, when cleaning the posterior molar area, it can be better attached to the tooth surface for cleaning, further improving the cleaning effect and making the use more comfortable; in addition, the size of the second mounting hole 112 located on the outer circle is larger than that of the first mounting hole 111, so that a denser first mounting hole 111 can be arranged on the inner circle of the brush head body 100, increasing the amount of bristles implanted on the brush head and improving the use experience of the brush head.

[0023] Furthermore, the first mounting hole 111 is square, and the second mounting hole 112 is oval. The outer edges of the brush head body 100 are all arc-shaped. The second mounting holes 112 arranged around the first mounting hole 111 are oval, and can be arranged to better fit the edge shape of the brush head body 100. For example, the shape of the second mounting hole 112 provided at the top of the brush head body 100 fits the edge of the brush head body 100, and the space of the brush head body 100 can be better utilized; the square shape of the second mounting hole 112 can be adjusted in angle arrangement to better utilize the gap between them, so that more bristles can be implanted on the brush head.

[0024] Still further, the starting end of the first arc surface 310 is an inclined surface 311. The starting end of the first arc surface 310 has the highest height, and an inclined surface 311 is formed at the connection between the starting end and the middle concave arc surface of the first arc surface 310. So that when cleaning the posterior molar area, the inclined surface 311 can contact the inner side of the tooth for cleaning, thereby improving the cleaning effect of the brush head.

[0025] As an embodiment, the height range of the bristles on the inclined surface 311 is 9 - 12 mm, and the diameter range of the bristles is 0.15 to 0.2 mm; the height range of the bristles in the first mounting hole 111 except for the inclined surface 311 is 8.5 to 10 mm, and the bristle diameter is 0.13 to 0.18 mm; the height range of the bristles in the second mounting hole 112 except for the inclined surface 311 is 8.5 to 11.5 mm, and the bristle diameter is 0.13 to 0.15 mm; the material of the bristles fixed in the first mounting hole 111 is nylon; the material of the bristles fixed in the second mounting hole 112 is nylon or PBT material. The corresponding material and the corresponding bristle diameter are adapted according to the use area, with high adaptability, improving the cleaning comfort and the user experience.

[0026] As an embodiment, referring to Figure 4 , the bottom of the connecting handle 200 is a connecting hole 210, and an arc-shaped clamping groove 220 is provided in a ring on the inner wall of the connecting hole 210; the bottom of the connecting handle 200 is a tapered hole with a gradually increasing diameter, and the annular clamping groove 220 provided on the inner wall is an arc-shaped groove, which can be quickly connected to the toothbrush handle for the convenience of users. Moreover, the connection between the clamping groove 220 and the inner wall of the connecting hole 210 is inclined, making the installation process smoother.

[0027] According to the disclosure and teaching of the above specification, those skilled in the art of the present invention can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
