[0046] Electric toothbrushes primarily rely on a built-in motor to transmit vibration or rotational force through an axial brush head. The brush disc structure on the brush head is the key component for power transmission, directly affecting the amplitude of the bristles and the cleaning power.

[0047] The existing toothbrush brush plate structure mostly adopts a simple one-piece design. When applied to toothbrushes, especially electric toothbrushes, it is difficult to balance cleaning effect and user comfort in terms of power transmission, swing amplitude control, and vibration stability, resulting in a poor user experience.

[0048] The purpose of this invention is to provide a brush head, toothbrush, and electric toothbrush that, through the reasonable arrangement of bristles on the brush plate 2, balances cleaning effect and user comfort in terms of power transmission, swing amplitude control, and vibration stability, thus greatly improving the user experience.

[0049] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] Example 1

[0051] This utility model embodiment provides a brush head, which includes: a base 1; the base 1 includes: a brush disc 2 and a brush rod 3 connected to each other; the brush disc 2 includes: a rib 6 and a plurality of bristle implantation components 8; the bristle implantation components 8 are provided with at least one bristle implantation hole 4; at least one pair of adjacent bristle implantation components 8 are connected by the rib 6; each bristle implantation hole 4 is provided with a bristle bundle; wherein, the bristle implantation holes 4 are arranged according to at least one preset arrangement rule.

[0052] For details, see Figure 1 The above-view diagram shows a brush head structure provided in this embodiment of the present invention, in which the brush disc 2 and the brush rod 3 are connected to each other.

[0053] Further, see Figure 2 The schematic diagram shown in this embodiment of the present invention provides a brush disk structure. The brush disk 2 is provided with multiple bristle-planting components 8, and adjacent bristle-planting components 8 are connected by ribs 6 to improve the relative stability between the bristle-planting components 8. Each bristle-planting component 8 has at least one bristle-planting hole 4 arranged sequentially. For example... Figure 2 The brush plate 2 shown in the figure has three hair implantation holes 4 on the left and right sides of the hair implantation component 8, and the remaining hair implantation components 8 have four hair implantation holes 4.

[0054] Further, see Figure 3 The diagram shows a top view of another brush disk provided in this embodiment of the present invention. Each bristle implantation component 8 in the brush disk 2 is provided with a bristle implantation hole 4.

[0055] In some preferred embodiments of this invention, the bristle implantation hole 4 can be a through hole penetrating the brush plate 2; in some preferred embodiments of this invention, the bristle implantation hole 4 is a concave structure with an opening on the front side of the brush plate 2; the bristle implantation holes 4 are arranged according to a preset arrangement rule. Bristle bundles can be set inside the bristle implantation hole 4, and appropriate bristles can be selected according to the specific usage scenario to provide moderate pressure when cleaning the tooth surface, without damaging the gums, and effectively removing dirt.

[0056] Furthermore, the bristle holes 4 are connected by ribs 6, which are located on the front of the brush plate 2, and can improve the stability of the brush plate 2 during the user's brushing process.

[0057] Specifically, the two hair implantation holes 4 are connected by a rib 6, and the height of the rib 6 is slightly lower than the height of the hair implantation hole 4. This ensures that the tooling used during the hair implantation process can be stably placed on the rib 6, thereby avoiding slippage or tilting of the tooling due to unstable support. The height of the hair implantation hole 4 above the rib 6 is between 0.8 and 1.2 mm.

[0058] Furthermore, the preset arrangement rules include at least one of the following: strip arrangement, concentric circle arrangement, or arc arrangement. The projection of the hair-implanting holes 4 onto the front of the brush plate 2 forms an orderly pattern.

[0059] The strip arrangement rule is that the axes of symmetry of at least one pair of adjacent ordered shapes lie on the same straight line. The number of straight lines is not specifically limited in this embodiment, but is preferably three. For example, see [link to example]. Figure 4 The diagram shown illustrates the relative positions of the bristle implantation holes 4 arranged in a strip-like pattern according to an embodiment of the present invention. In this diagram, the bristle implantation holes 4 on the brush plate 2 are arranged in three straight lines. This arrangement increases the density and contact area of ​​the bristles, enhancing their cleaning efficiency in the vertical direction. Furthermore, because the bristle implantation holes 4 in each row are linear, they effectively disperse lateral stress, making it less likely for the brush plate 2 to shift during vibration, thereby reducing wear on the electric toothbrush structure caused by vibration.

[0060] The concentric circle arrangement rule is that the centers of multiple ordered graphics are arranged in concentric circles. The number of concentric circles is not specifically limited in this embodiment of the invention, but is preferably four. For example, see [link to example]. Figure 5 The diagram shown is a schematic representation of the relative positions of the implantation holes 4 arranged in a concentric circle pattern according to an embodiment of the present invention. The diagram includes four concentric circles, with the multiple implantation holes 4 spaced at preset intervals and not aligned on any of the concentric circles. This arrangement helps to evenly distribute stress during vibration. Because the stress concentration point of each circle expands outward along the radius, vibration transmission is more stable, avoiding deformation or fatigue of the brush plate 2 due to excessive local stress.

[0061] The arc arrangement rule is that the centers of at least one pair of adjacent ordered shapes lie on the same arc. The number of arcs is not specifically limited in this embodiment, but is preferably five. For example, see [link to example]. Figure 6 The diagram shown illustrates the relative positions of the implanted bristles 4 arranged in an arc-shaped pattern according to an embodiment of this invention. The diagram shows five arcs, with three implanted bristles 4 on each arc. This arrangement of the implanted bristles 4 allows the bristles to be optimized according to the curvature of the user's oral cavity, increasing the contact area with the tooth surface. During vibration, the arc-shaped arrangement can evenly distribute stress, avoiding damage to the brush plate 2 caused by localized stress concentration. Furthermore, the arc-shaped arrangement allows for adjustment of the pore density in different areas, controlling the amplitude and frequency of vibration, thereby improving the cleaning effect.

[0062] Furthermore, in the usage scenario of electric toothbrushes, the brush plate 2 is the part that carries the bristles. The power system of the electric toothbrush transmits the force of vibration or rotation to the bristles through the brush plate 2. Therefore, the design of the brush plate 2 must not only take into account the arrangement of the bristles, but also ensure the contact effect between the bristles and the teeth. Different shapes can change the density of the bristle arrangement and the contact area, thereby adapting to different cleaning needs.

[0063] A well-designed 4-hole arrangement can reduce energy loss during vibration transmission and improve the power transmission efficiency of the electric toothbrush. The optimized 4-hole arrangement also reduces motor load and battery consumption, thereby extending the electric toothbrush's battery life.

[0064] A well-designed arrangement of the bristle holes 4 enables a lightweight design, making the brush plate 2 structure more flexible and reducing vibration shift and noise issues caused by uneven mass of the brush plate 2 during operation. Different arrangements, such as concentric circles, strips, and arcs, can help the electric toothbrush more effectively distribute and transmit stress during vibration, preventing fatigue or damage to the brush plate 2 due to prolonged use.

[0065] Furthermore, through a well-designed arrangement of the hair follicle holes 4, manufacturers can flexibly adjust the vibration frequency and amplitude of the electric toothbrush to suit the cleaning needs of different users. For example, for users with sensitive gums, the amplitude can be reduced by optimizing the arrangement of the hair follicle holes 4; while for users with severe plaque, the amplitude can be increased through a specific hair follicle hole 4 layout to improve cleaning efficiency.

[0066] This utility model provides a brush head, which includes: a base 1; the base 1 includes: a brush disc 2 and a brush rod 3 connected to each other; the brush disc 2 includes: a rib 6 and a plurality of bristle-planting components 8; each bristle-planting component 8 is provided with at least one bristle-planting hole 4; at least one pair of adjacent bristle-planting components 8 are connected by the rib 6; each bristle bundle is provided in the bristle-planting hole 4; wherein, the bristle-planting holes 4 are arranged according to at least one preset arrangement rule; by reasonably arranging the bristles on the brush disc 2, the cleaning effect and user comfort are taken into account in terms of power transmission, swing amplitude control, and vibration stability, which greatly improves the user experience.

[0067] Example 2

[0068] This utility model provides another brush head, implemented based on the above embodiments. In some preferred embodiments of this utility model, the brush head further includes: a retaining element 5; the retaining element 5 is disposed within the bristle implantation hole 4; and a bristle bundle is disposed within the retaining element 5.

[0069] For details, see Figure 7 The left view of another brush head provided in this embodiment of the present invention is shown, with the original component still set inside the hair implantation hole 4.

[0070] Furthermore, in some preferred embodiments of this utility model, the bristle bundle is pressed into the bristle implantation hole 4 by a retainer, and the bristle implantation hole 4 has a fixing structure that fits into the retainer.

[0071] Specifically, the bristle bundle can be directly pressed into the bristle implantation hole 4 using a retainer, with the middle portion of the bristles pressed into the hole 4 and the two ends of the bristles protruding from the hole 4. The fixing structure can be a protrusion on the inner wall of the bristle implantation hole 4. In some preferred embodiments of this invention, the protrusion can be an annular protrusion. After pressing the bristle bundle down below the annular protrusion, the retainer is fixed in the bristle implantation hole 4 by the protrusion.

[0072] Furthermore, the fixing structure can also be formed by heating the fixing device to melt part of the inner wall of the hair implantation hole 4 after the fixing device enters the hair implantation hole 4.

[0073] Furthermore, in some preferred embodiments of this utility model, the fixing structure is a recessed fitting groove on the inner wall of the hair implantation hole 4; the bristle bundle is pressed down by the fixing device until the end of the fixing device is embedded in the fitting groove.

[0074] Specifically, the retainer can be slightly larger than the diameter of the inner wall of the hair implantation hole 4. The corresponding fixing structure is a recessed fitting groove on the inner wall of the hair implantation hole 4. The retainer is pressed down until it can be just embedded in the fitting groove. For example, the structure of the retainer can be a cross-shaped structure or a mesh structure. The hair can pass through the mesh structure and remain in a position parallel to the extension direction of the hair implantation hole 4.

[0075] Furthermore, in some preferred embodiments of this invention, the shape of the projection of the hair implantation hole 4 onto the front of the brush disk 2 includes at least one of the following: a circle or a polygon.

[0076] Specifically, the pore 4 can be any of the following shapes: circular, polygonal, arc-shaped, or multi-arc; for example, see [link to example]. Figure 8 The diagram shown is a schematic representation of the shape of a circular hair implantation hole provided in this embodiment of the present invention. Figure 9 The schematic diagram shown is of a rhomboid hair-planting hole shape provided by the embodiment of this utility model. Figure 10 The diagram shown illustrates an oval-shaped bristle implantation hole according to an embodiment of the present invention. These hole shapes can be optimized based on the arrangement of the bristles and the cleaning angle. The variety and precision of the bristle implantation holes 4 are designed to ensure that the bristles contact the teeth at the optimal angle during use, thereby improving the cleaning effect.

[0077] The bristle implantation hole 4 set on a brush plate 2 can have only one shape or be a combination of multiple shapes. The structure of the corresponding retainer is also deformed according to the shape of the bristle implantation hole 4, as long as the bristles can be pressed into the bristle implantation hole 4 and fixed.

[0078] For example, the spacing between the hair implantation holes 4 is between 0.7-1mm, the diameter of the hair implantation holes 4 is less than 3mm and the length-to-width ratio is less than 2:1.

[0079] Furthermore, in some preferred embodiments of this utility model, the brush head further includes: an elastic element 7; the elastic element 7; the elastic element 7 covers the outer side of the substrate 1.

[0080] For details, please refer to [link / reference]. Figure 7 The elastic element 7 is mainly used to cover the brush head and neck. Its excellent resilience provides moderate softness and cushioning, increasing user comfort during use and preventing direct contact between the hard material of the brush head and teeth, reducing friction and discomfort. The elastic element 7 also has anti-slip and drop-resistant functions, making the toothbrush more durable. The lightweight and resilient elastic element 7 reduces energy loss during vibration transmission, optimizes the motor's vibration output efficiency, improves the toothbrush's cleaning effect, and simultaneously reduces noise and vibration wear on the toothbrush structure.

[0081] Furthermore, in some preferred embodiments of this utility model, the elastic element 7 is made of transparent rubber.

[0082] Specifically, the transparent coating can be customized into various shapes on the brush plate 2 to create brand uniqueness. At the same time, the transparency allows users to see the internal structure or the brush head fixing situation, which helps to showcase the design details and quality of the toothbrush, enhance user trust, and the transparent coating makes it easier to observe whether there is dirt accumulation, making it convenient for users to clean in time.

[0083] Furthermore, in some preferred embodiments of this utility model, the elastic element 7 is made of non-transparent rubber.

[0084] Specifically, non-transparent overlays offer a wide range of color options, which is beneficial for personalized brand design and allows users to distinguish toothbrushes from different family members. Non-transparent overlays can incorporate matte, pearlescent, and other effects to enhance the tactile and visual appeal, while also reducing fingerprint and water stain residue.

[0085] Furthermore, in some preferred embodiments of this utility model, the hardness of the elastic element 7 is greater than 30 degrees, and the hardness of the elastic element 7 is less than 70 degrees.

[0086] Specifically, the elastic element 7 has a hardness between 30-70°, with 40° being the preferred option. This effectively balances comfort and durability. A hardness of 40° falls within a moderate range of softness, ensuring that the elastic element 7 is neither too hard nor too soft, providing good cushioning during toothbrush use and preventing the hard materials of the brush head from directly contacting the teeth. This hardness makes the brush head gentler when cleaning teeth, reducing discomfort caused by friction, making it particularly suitable for users with sensitive teeth or gums. Furthermore, the 40° hardness of the elastic element 7 also provides appropriate anti-slip properties. It increases the stability of the user's grip, preventing the toothbrush from slipping when hands are wet or in contact with water, thus improving safety and convenience. Finally, the 40° hardness of the elastic element 7 provides moderate elasticity and good deformation recovery ability, allowing it to be repeatedly compressed and quickly return to its original shape during use. This characteristic effectively reduces energy loss during the vibration process of the electric toothbrush, improving cleaning effectiveness.

[0087] Furthermore, in some preferred embodiments of this invention, the height of the retaining element 5 protruding from the front of the brush disk 2 is higher than the height of the rib 6 protruding from the front of the brush disk 2. The rib 6 is lower than the height of the retaining element 5, allowing the elastomer to effectively wrap around the rib 6. This enhances the structural stability of the brush head and improves comfort and extends its service life.

[0088] Furthermore, in some preferred embodiments of this utility model, the substrate 1 is manufactured based on an integral molding process, which increases the stability between the brush plate 2 and the brush rod 3.

[0089] This utility model embodiment provides a brush head that, through technical optimization of the arrangement and combination of bristle holes 4, can achieve lightweighting while maintaining the strength of the brush disk 2, thereby improving vibration transmission efficiency and swing amplitude consistency, and providing users with a more efficient cleaning experience.
