[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 4. This embodiment provides a toothbrush, including a rigid toothbrush handle 1. The rigid toothbrush handle 1 includes a brush head connecting part 11, a handle part 12, and a grip part 13 connected in sequence. The handle part 12 has a handle recess 121 recessed inward from the circumference. The handle recess 121 is provided with a soft covering 2. The soft covering 2 has a plurality of anti-slip protrusions 21 and / or anti-slip grooves 22. The toothbrush of this embodiment achieves an anti-slip effect through the anti-slip protrusions 21 and / or anti-slip grooves 22 on the soft covering 2. At the same time, the soft covering 2 provides elastic cushioning for the user's fingers, so that the user will not feel finger pain when pressing hard during brushing, resulting in high comfort and a good user experience.

[0026] Specifically, the soft covering 2 completely covers the outer periphery of the hand part 12, which can effectively block the flow lines generated at the hand part 12 during injection molding.

[0027] Specifically, the soft cover 2 may only have anti-slip protrusions 21, or only have anti-slip grooves 22, or may have both anti-slip protrusions 21 and anti-slip grooves 22. Preferably, the soft cover 2 in this embodiment has both anti-slip protrusions 21 and anti-slip grooves 22.

[0028] Furthermore, the height difference between the top surface of the anti-slip protrusion 21 and the surface of the soft cover 2 is ≤0.3mm, and the height difference between the bottom surface of the anti-slip groove 22 and the surface of the soft cover 2 is ≤0.3mm. A height difference of ≤0.3mm achieves the anti-slip effect while preventing a decrease in user experience due to excessive height difference.

[0029] Furthermore, the anti-slip protrusions 21 and / or anti-slip grooves 22 have polygonal cross-sections. The structure is simple and aesthetically pleasing. Preferably, in this embodiment, the anti-slip protrusions 21 and / or anti-slip grooves 22 are hexagonal.

[0030] Furthermore, the anti-slip protrusions 21 and / or anti-slip grooves 22 are provided on the front end face of the soft cover 2. When brushing teeth, the thumb mainly presses on the front end face of the soft cover 2, and the anti-slip protrusions 21 and / or anti-slip grooves 22 are correspondingly concentrated on the front end face of the soft cover 2, which can achieve a better anti-slip effect.

[0031] Furthermore, to address the issue of reduced bending resistance of the hand-operated part 12 due to increased comfort, the thickness of the soft cover 2 is ≤2.5mm. Specifically, increasing the thickness of the soft cover 2 can improve finger pressing comfort; however, as the thickness of the soft cover 2 increases, the thickness of the hand-operated part 12 decreases accordingly. When the thickness of the hand-operated part 12 decreases to a certain extent, it will lead to a decrease in the bending resistance of the hand-operated part 12. Therefore, a thickness of ≤2.5mm for the soft cover 2 is preferable.

[0032] Furthermore, to enhance user comfort, the surface of the soft cover 2 is smoothly connected to the surface of the brush head connection portion 11 without any steps, and the surface of the soft cover 2 is smoothly connected to the surface of the grip portion 13 without any steps.

[0033] Furthermore, the hand grip 12 is provided with a connecting reinforcing rib 122, which is located at the connection between the hand grip 12 and the brush head connection 11 and / or at the connection between the hand grip 12 and the grip part 13. The connecting reinforcing rib 122 can reduce stress concentration at the two connecting ends of the hand grip 12, thereby improving the overall bending resistance of the hand grip 12.

[0034] Furthermore, since the front and rear faces of the connection between the hand-holding part 12 and the brush head connecting part 11, as well as the front face of the connection between the hand-holding part 12 and the grip part 13, are areas that are easily bent under stress when brushing teeth, it is preferable that the connecting reinforcing rib 122 is provided at least on the front and rear faces of the connection between the hand-holding part 12 and the brush head connecting part 11 and / or on the front face of the connection between the hand-holding part 12 and the grip part 13.

[0035] Preferably, the connecting reinforcing rib 122 extends obliquely from the connection point between the hand grip 12 and the brush head connection 11 to the hand grip 12, and the connecting reinforcing rib 122 extends obliquely from the connection point between the hand grip 12 and the grip 13 to the hand grip 12.

[0036] Furthermore, to improve the comfort and anti-slip properties of the grip portion 13 when held by fingers, the rear end face of the grip portion 13 is provided with a grip groove 131 extending along the length direction of the grip portion 13, and a soft covering strip 3 is provided on the grip groove 131. On the one hand, the soft covering strip 3 can increase the fit and friction between the fingers and the rear end face of the grip portion 13, thereby achieving a better anti-slip effect. On the other hand, the soft covering strip 3 can appropriately reduce the thickness of the grip portion 13, thereby reducing the shrinkage that occurs during the injection molding of the grip portion 13.

[0037] Furthermore, to enhance the anti-slip effect, the grip groove 131 is connected to the press-grip cavity 121. The soft cover 2 and the soft cover strip 3 are integrally formed. The soft cover strip 3 has a first anti-slip protrusion 31 protruding from its surface, and the soft cover 2 has a second anti-slip protrusion 23 protruding from its surface and connected to the first anti-slip protrusion 31. The first anti-slip protrusion 31 and the second anti-slip protrusion 23 can further increase the fit and friction between the fingers and the press-grip part 12 and the rear end face of the grip part 13, achieving a better anti-slip effect.

[0038] Furthermore, the hard toothbrush handle 1 is made of PP, POM, or PBT, while the soft covering sleeve 2 and soft covering strip 3 are made of TPE. PP is polypropylene, a semi-crystalline thermoplastic polymer made from propylene monomers through an addition polymerization reaction, possessing properties such as lightness, wear resistance, and antibacterial properties. POM is polyoxymethylene, also known as acetal resin, polyoxymethylene, or polyacetal, a thermoplastic crystalline polymer with similar hardness, strength, and rigidity to metals. It exhibits excellent self-lubrication, good fatigue resistance, and elasticity over a wide range of temperature and humidity. PBT is polybutylene terephthalate, a translucent or opaque crystalline thermoplastic polyester resin, characterized by high temperature resistance, moisture resistance, oil resistance, chemical corrosion resistance, and ease of molding. TPE is a thermoplastic elastomer, a new type of polymer material between rubber and resin, possessing the dual properties and broad characteristics of both rubber and plastic.
