Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oral care tools, in particular to a toothbrush and a preparation method thereof. BACKGROUND

[0002] Some existing toothbrushes have a detachable brush head and handle, and the handle is provided with a non-slip pad. The non-slip pad is generally fixed by sleeving or bonded on the handle by glue. However, the toothbrush needs to be frequently contacted with water and toothpaste foam in daily use. In a long-term water soaking environment, on the one hand, the bonded layer of glue will accelerate failure, the fitting gap between the non-slip pad and the handle, and the connection gap between the brush head and the handle are easy to penetrate water stains, which destroys the assembly stability of the non-slip pad and the handle, and makes the non-slip pad prone to displacement, loosening or even overall falling off, directly losing the non-slip function. On the other hand, the long-term soaking of water stains will cause the corrosion and aging of the non-slip pad, affecting the mildew resistance and stain resistance of the non-slip pad, and the connection gap between the non-slip pad and the handle will also hide dirt, limiting the service life of the handle.

[0003] The present application is proposed to solve the problems in the prior art. SUMMARY

[0036] Embodiment two: The embodiment two provides another optional embodiment of the toothbrush, and the difference between the embodiment two and the above-mentioned embodiment one is that the anti-skid piece 3 is integrally formed with the brush head handle 1 through the first portion 31, and the second portion 32 extends from the first portion 31 along the axial direction of the brush head handle 1 to form the holding handle 2.

[0037] In the embodiment, during processing, the anti-skid piece 3 can be injection molded on the brush head handle 1 through a gluing process, which simplifies the assembly process between the anti-skid piece 3 and the brush head handle 1, improves the production efficiency of the anti-skid piece 3 and the brush head handle 1, and is also convenient for users to disassemble and assemble the brush head handle 1 and the anti-skid piece 3 in actual application. Moreover, the integrally formed structure between the anti-skid piece 3 and the brush head handle 1 fundamentally avoids the connection loosening problem of the anti-skid piece 3 caused by assembly process error, external force impact or long-term use aging, thereby improving the durability and anti-skid performance of the anti-skid piece 3. In addition, the integrally formed structure between the anti-skid piece 3 and the brush head handle 1 reduces the gap or connection interface between the anti-skid piece 3 and the brush head handle 1, effectively avoids the accumulation of dirt such as water stains and toothpaste residues in the gap between the anti-skid piece 3 and the brush head handle 1, improves the sanitary performance of the toothbrush, further improves the anti-aging and anti-corrosion ability of the anti-skid piece 3 in a humid environment, and prolongs the service life of the whole brush head handle 1. Furthermore, by arranging the first portion 31 and the second portion 32 of the anti-skid piece 3 in the axial direction, the structure of the anti-skid piece 3 and the mounting cavity 21 can be simplified, thereby simplifying the connection structure between the brush head handle 1 and the holding handle 2 and ensuring the smoothness of disassembly and assembly between the brush head handle 1 and the holding handle 2.

[0038] In the embodiment, the anti-skid piece 3 is arranged as a linear anti-skid piece, which simplifies the structure of the anti-skid piece 3, thereby reducing the injection difficulty of the anti-skid piece 3, improving the processing efficiency of the anti-skid piece 3, and reducing the injection mold cost of the anti-skid piece 3.

[0039] Example 3: This third embodiment provides another optional embodiment of the toothbrush. The difference between this third embodiment and the first and second embodiments is that the anti-slip component 3 is mounted on the brush head handle 1 through the first part 31, and the second part 32 is disposed on one side of the first part 31 along the axial direction of the brush head handle 1. In this embodiment, the anti-slip component 3 can be fixedly connected to the brush head handle 1 by ultrasonic welding or adhesive bonding, so that the anti-slip component 3 can be integrated into the brush head handle 1, ensuring that the user can disassemble and replace the brush head handle 1 and the anti-slip component 3 together. In addition, it is beneficial to enhance the processing flexibility of the anti-slip component 3 during the production and processing process. Secondly, in this embodiment, the anti-slip component 3 is treated as a component independent of the brush head handle 1. During the production and processing process, the material, shape or size of the anti-slip component 3 can be flexibly adjusted to meet the anti-slip needs of different user groups. In addition, by setting the first part 31 and the second part 32 of the anti-slip component 3 along the axial direction, the structure of the anti-slip component 3 and the mounting cavity 21 can be simplified, thereby simplifying the connection structure between the brush head handle 1 and the grip handle 2, and ensuring the smooth disassembly and assembly between the brush head handle 1 and the grip handle 2.

[0040] Example 4: On the other hand, such as Figure 7 As shown, the present invention also provides a method for preparing a toothbrush, comprising at least the following steps: The brush head handle 1 is manufactured using a one-piece molding process; An anti-slip component 3 is integrally formed on the brush head handle 1, or an anti-slip component 3 is installed on the brush head handle 1; wherein, the anti-slip component 3 is embedded in the brush head handle 1 through the first part 31. The grip 2 is manufactured by a one-piece molding process; wherein, the grip 2 has a mounting cavity 21 corresponding to the second part 32 of the anti-slip part 3.

[0041] The brush head handle 1 and grip handle 2 can be manufactured separately using an integrated molding process, avoiding the complex process of assembling the brush head handle 1 and grip handle 2 after undergoing multiple processing steps (such as cutting, grinding, and splicing) in traditional toothbrush production. This solution simplifies the process flow of the brush head handle 1 and grip handle 2, thereby improving the production and assembly efficiency of the brush head handle 1 and grip handle 2, as well as enhancing the structural strength and durability of the brush head handle 1 and grip handle 2. At the same time, the anti-slip component 3 is integrated and embedded in the brush head through the first part 31. The anti-slip component 3 is integrated into the brush head handle 1 or mounted on the brush head handle 1, so that the anti-slip component 3 can be installed and removed synchronously with the brush head handle 1 relative to the grip handle 2. This improves the convenience for users to replace the brush head handle 1 and the anti-slip component 3, and also improves the durability and hygiene performance of the grip handle 2. Furthermore, the anti-slip performance of the toothbrush can be improved by replacing the anti-slip component 3. In addition, the toothbrush is manufactured through the above steps, which significantly shortens the production cycle of a single toothbrush and improves the efficiency and capacity of large-scale toothbrush production.

[0042] As an optional embodiment of the present application, the brush head handle 1 can be formed by injection molding or mold pressing of hard material such as plastic, and then the anti-skid member 3 is processed on the brush head handle 1, wherein the anti-skid member 3 can be directly injection molded on the brush head handle 1, or the anti-skid member 3 can be first processed, and then fixedly connected on the brush head handle 1 by ultrasonic welding or glue bonding.

[0043] As an optional embodiment of the present application, the holding handle 2 can be formed by plastic injection molding, or by cutting or smelting of metal material, or by ceramic sintering, which is not specifically limited here; after the holding handle 2 is completely processed, the surface of the holding handle 2 can be treated by electroplating, paint spraying or electrophoresis for corrosion protection.

[0044] As an optional embodiment of the present application, the anti-skid member 3 is preferably injection molded on the brush head handle 1 by encapsulation process, and the injection mold has an injection cavity corresponding to the anti-skid member 3; since an injection gate is usually formed on the surface of the injection molded part during injection molding, in the present embodiment, soft material is injected on the back side of the brush head handle 1 (i.e. the side opposite to the anti-skid member 3), the soft material flows along the corresponding injection cavity and is formed on the brush head handle 1 to form the anti-skid member 3 with the sealing portion 33; after the injection is completed, the injection gate is formed on the back surface of the sealing portion 33, avoiding the injection gate on the surface of the anti-skid member 3, which is beneficial to the appearance of the surface of the anti-skid member 3.

[0045] The above is only used as an embodiment to further illustrate the technical content of the present application, so that the reader can more easily understand, but it does not mean that the embodiments of the present application are limited to this, any technical extension or re-creation made according to the present application is protected by the present application.
