[0025] 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.
[0026] 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.
[0027] First embodiment
[0028] Figure 1 is a schematic diagram of a toothbrush head according to the first embodiment. Figure 2 FIG. 1 is an exploded view of the structure of the toothbrush head according to the first embodiment. Figure 1 and Figure 2 As shown, a toothbrush head with a pattern structure in this embodiment includes bristles 11, a brush head body 12 and a transparent wrapping layer 15. The fixed end 111 of the bristles 11 is fixed to the side of the free end of the brush head body 12 facing away from the bristles 11, and the fixed end 111 of the bristles 11 is formed with a pattern structure 13. The transparent wrapping layer 15 wraps the side of the free end of the brush head body 12 facing away from the bristles 11 and the pattern structure 13.
[0029] According to the technical solution of the present application, a pattern structure 13 is formed on the fixed end 111 of the bristle 11, which is then wrapped with a transparent wrapping layer 15 to show the pattern. The fixed end 111 of the bristle 11 is used to embed the pattern in the toothbrush head, thereby preventing the pattern from falling off or being damaged during use, ensuring the durability of the pattern and being more environmentally friendly.
[0030] In this embodiment, the pattern structure 13 includes a substrate and a printing layer 131, the substrate is composed of the fixed end 111 of the bristle 11, and the printing layer 131 is formed on the substrate. Optionally, the printing layer 131 can be formed on the substrate by hot melting, gluing, stickers, laser printing, etc. Since the fixed end 111 of the bristle 11 is used as the substrate, a surface for forming the printing layer 131 is provided, which reduces the difficulty of forming the printing layer 131. At the same time, there is no need to set up other additional structures for providing the substrate, which is conducive to reducing the thickness of the toothbrush head.
[0031] After one end of the bristle 11 passes through the planting hole on the brush head body 12, the end is melted to form a fixed end 111 to fix the bristle 11 on the brush head body 12. In this embodiment, the fixed end 111 of the bristle 11 is melted into a whole piece, and the surface of the fixed end 111 facing the transparent wrapping layer 15 is flat, so that it is easier to form the printed layer 131. Optionally, the printed layer 131 can be used to display the brand logo, or to define the logo of different categories (such as functions, applicable objects, etc.) of toothbrush heads or other patterns for decoration.
[0032] In this embodiment, the transparent wrapping layer 15 refers to a material layer with a certain degree of transparency, and it only needs to be able to show the embedded pattern structure 13 so that the pattern structure 13 can play a display function, and it does not need to be completely transparent. Optionally, the transparent wrapping layer 15 can be a soft material layer or a hard material layer. Preferably, the transparent wrapping layer 15 is a soft material layer, so that it can further prevent the hard part of the toothbrush head from colliding with the oral cavity, thereby improving the user experience.
[0033] In actual implementation, the color of the bristles 11 can also be a color corresponding to the pattern structure 13, for example, as a background color, or combined with the pattern of the printed layer 131, thereby reducing the area of the printed layer 131 and being more environmentally friendly.
[0034] Second embodiment
[0035] The main difference between this embodiment and the first embodiment is that the fixed ends of the bristles are melted into a whole piece, and the surface on the side facing the transparent wrapping layer has protrusions and / or depressions forming a pattern.
[0036] Optionally, the step of forming the pattern of protrusions and / or depressions can be performed after the fixed end of the bristles is melted into a flat whole piece, for example, by laser engraving the fixed end. It can also be performed simultaneously with the melting of the fixed end of the bristles, using a three-dimensional melting head to directly melt the fixed end with protrusions and / or depressions.
[0037] Optionally, the pattern of the printed layer can cooperate with the protrusions and / or depressions that form the pattern to present a three-dimensional pattern structure, for example, presenting three-dimensional effects such as water ripples and clouds, so as to be suitable for displaying richer pattern content.
[0038] Third embodiment
[0039] like Figure 3 As shown, the pattern structure 23 includes a substrate and a printing layer 231. The substrate is composed of the fixed end 211 of the bristle 21. The main difference between this embodiment and the first embodiment is that the fixed end 211 of the bristle 21 includes multiple independent parts, and the printing layer 231 is formed in the multiple independent parts respectively.
[0040] An independent part means that the fixed ends 211 of different parts are not connected to each other. For example, the multiple independent parts include a first part 232 and a second part 233, and the first part 232 and the second part 233 are not connected to each other. Each independent part can be a fixed end 211 formed by melting a single bundle of bristles 21, that is, the end of a bundle of bristles 21 is independently melted into a fixed end 211. Each independent part can also be a fixed end 211 formed by melting multiple bundles of bristles 21, that is, the ends of multiple bundles of bristles 21 are melted together to form a fixed end 211. In this case, the pulling force of the bristles 21 of this part can be increased. Therefore, when designing the pattern structure 23, the number of bristle bundles required for each independent part can be designed in combination with the requirements of the pulling force of the bristles 21 in various areas of the toothbrush head.
[0041] The shapes of the first part 232 and the second part 233 can be different, so that the first part 232 and the second part 233 can be matched to form a desired pattern, for example, a first part 232 and four surrounding second parts 233 can form a cat's paw shape, but it is not limited to this. Figure 4 A bristle melting head with a three-dimensional cavity can be used to melt the ends of the bristles 21. During the melting process, each independent part is formed at one time, and the required shape of each part is obtained.
[0042] Please refer to Figure 5 The brush head body 22 is provided with a hair planting hole, one end of the bristle 21 passes through the hair planting hole and then melts to form a fixed end 211. The through-hole shapes of different hair planting holes correspond to the shapes of the corresponding independent parts. For example, the shape of the first hair planting hole 221 corresponds to the first part 232, and the shape of the second hair planting hole 222 corresponds to the second part 233. Thus, the combination Figure 4 The bristle melting head with three-dimensional concave cavities of different shapes can be melted into the desired shape more easily.
[0043] The printing layer 231 is formed in a plurality of independent parts, that is, the printing layer 231 also includes a plurality of independent parts, so that a richer and more vivid pattern structure 23 is formed by matching the shape of the fixing end 211 with the pattern of the printing layer 231. The method for forming the printing layer 231 is as described in the first embodiment and will not be repeated.
[0044] Fourth embodiment
[0045] The main difference between this embodiment and the aforementioned embodiment is that the pattern structure is formed by the fixed ends of the bristles, that is, the printing layer may not be provided.
[0046] In this embodiment, the fixed end of the bristle includes a plurality of independent parts, and the plurality of independent parts form a pattern structure. Figure 3The toothbrush heads shown are the same. The independent parts in the pattern structure refer to the fixed ends of different parts that are not connected to each other. Each independent part can be a fixed end formed by melting a single bundle of bristles, that is, the end of a bundle of bristles is independently melted into a fixed end. Each independent part can also be a fixed end formed by melting multiple bundles of bristles, that is, the ends of multiple bundles of bristles are melted together to form a fixed end.
[0047] The shapes of the individual parts can be different, so that the desired pattern can be matched, such as forming a cat's paw shape, etc., but not limited to this. Figure 4 The bristle melting head with a three-dimensional cavity melts the ends of the bristles. During the melting process, each independent part is formed at one time and the required shape of each part is obtained.
[0048] The brush head body is provided with a hair planting hole, and one end of the bristle passes through the hair planting hole and then melts to form a fixed end. Similar to the third embodiment, the through-hole shape of the different hair planting holes corresponds to the shape of the corresponding independent part, so that the combination Figure 4 The bristle melting head with three-dimensional concave cavities of different shapes can be melted into the desired shape more easily.
[0049] In actual implementation, the color of the bristles can also be the color corresponding to the pattern structure. For example, different independent parts of the fixed end can use different or the same colors. Combined with the shape of the fixed end, a richer and more vivid embedded pattern can be formed without setting a printing layer.
[0050] Fifth embodiment
[0051] The main difference between this embodiment and the fourth embodiment is that the pattern structure is formed by the fixed ends of the bristles, the fixed ends of the bristles are melted into a whole piece, and have protrusions and / or depressions forming the pattern structure on the side facing the transparent wrapping layer.
[0052] Similar to the second embodiment, the step of forming the pattern of protrusions and / or depressions can be performed after the fixed end of the bristles is melted into a flat whole piece, for example, by laser engraving the fixed end. It can also be performed simultaneously with the melting of the fixed end of the bristles, using a three-dimensional melting head to directly melt the fixed end with protrusions and / or depressions.
[0053] Optionally, the color of the bristles can also be a color corresponding to the pattern structure, so as to cooperate with the protrusions and / or depressions that form the pattern to present a three-dimensional pattern structure, such as presenting three-dimensional effects such as water ripples and clouds. Even when a printing layer is not set, a richer and more vivid embedded pattern can be formed.
[0054] The present application also provides a toothbrush, comprising a toothbrush head with a patterned structure as described in any of the above embodiments.
[0055] The toothbrush head and toothbrush with a pattern structure of the present application, the toothbrush head includes bristles, a brush head body and a transparent wrapping layer; the fixed end of the bristles is fixed to the side of the brush head body facing away from the free end of the bristles; the fixed end of the bristles is formed with a pattern structure; the transparent wrapping layer wraps the side of the brush head body facing away from the free end of the bristles and the pattern structure. The present application sets ribs on the brush head body, 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. The technical solution of the present application uses the fixed end of the bristles to realize the embedded pattern in the toothbrush head, which can ensure the durability of the pattern and is more environmentally friendly.
[0056] 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.
