Description

Technical Field

[0001] This utility model relates to the field of toothbrush technology, and in particular to a toothbrush that can clean deep between teeth. Background Technology

[0002] The main function of a toothbrush is to remove plaque and food debris. Using a toothbrush correctly can effectively clean the mouth, prevent oral diseases, and maintain oral health. Toothbrushes can be divided into soft-bristled toothbrushes and hard-bristled toothbrushes according to the softness or hardness of the bristles. Generally speaking, soft-bristled toothbrushes are less irritating to the gums and are suitable for most people. Hard-bristled toothbrushes have stronger cleaning power but can damage the gums and are not suitable for long-term use. Traditional toothbrush bristle bundles have a circular or elliptical structure, which limits the bristle planting area per unit area and restricts the effectiveness of the toothbrush. In addition, the uniform softness and hardness of traditional toothbrush bristles leads to an unreasonable functional design of the toothbrush head, making it difficult for the bristles to clean food residue and plaque in the gaps between teeth. To address these issues, this utility model discloses a toothbrush that can deeply clean between teeth. Utility Model Content

[0003] The purpose of this invention is to provide a toothbrush that can deeply clean between teeth, solving the technical problems of traditional toothbrush bristle bundles having a circular or elliptical structure, which results in a limited bristle planting area per unit area, thus limiting the effectiveness of the toothbrush. In addition, the uniform softness and hardness of traditional toothbrush bristles leads to unreasonable functional design of the toothbrush head, making it difficult for the bristles to clean food residue and dental plaque between teeth.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A toothbrush capable of deep cleaning between teeth includes a toothbrush head, a bristle-embedded surface on one side of the toothbrush head, and a bristle tuft assembly disposed on the bristle-embedded surface. The bristle tuft assembly includes a tooth surface bristle tuft group located in the middle region of the bristle-embedded surface and a tooth interdental bristle tuft group located in the top and bottom regions of the bristle-embedded surface. The cross-section of the bristles in the bristle tuft assembly is a regular hexagonal structure, and the hardness of the bristles in the tooth interdental bristle tuft group is greater than that of the bristles in the tooth surface bristle tuft group.

[0005] Beneficial effects: This toothbrush, capable of deep cleaning between teeth, features stiffer interdental bristles distributed on either side of softer tooth surface bristles. This allows the tooth surface bristles to deform easily under pressure during brushing, better conforming to the curved surfaces of teeth. It provides a gentle yet thorough cleaning of plaque and stains on the tooth surface, while the interdental bristles, with their ability to reach deeper into the gaps between teeth and provide sufficient support, effectively cleans within these spaces, removing food debris and plaque. The copper-embedded bristles securely hold the bristles in place, ensuring their stability and extending the toothbrush's lifespan. The hexagonal cross-section of the bristles increases the contact area between the bristles and the tooth surface and gaps. Compared to bristles with a circular cross-section, the hexagonal structure has more angles, which better conform to the shape of the gaps during brushing, thus improving cleaning efficiency.

[0006] Furthermore, the bristle bundles within the bristle bundle assembly are mirror-distributed about the central axis of the toothbrush head, and the bristles located on the same side of the central axis of the toothbrush head are equidistantly distributed.

[0007] Furthermore, the width of the bristle bundles within the interdental brush bristle bundle group gradually increases from the top or bottom area of ​​the toothbrush head towards the middle area.

[0008] Furthermore, each bristle bundle in the bristle bundle assembly has a free end away from the bristle planting surface, and adjacent bristle bundles are arranged parallel to each other.

[0009] Furthermore, the bristle implantation surface is provided with multiple bristle implantation holes, and the bristle bundles in the bristle bundle assembly are inserted into the corresponding bristle implantation holes through copper sheets.

[0010] Furthermore, the copper sheet of each bristle bundle in the bristle bundle assembly is used to bind multiple bristles. Attached Figure Description

[0013] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0014] See Figures 1 to 2 As shown, a toothbrush that can clean deep between teeth includes a toothbrush head 1, a bristle-embedded surface 2 disposed on one side of the toothbrush head 1, and a bristle bundle assembly 3 disposed on the bristle-embedded surface 2. Specifically, the toothbrush head 1 has two free ends, one of which is flat and the other is rod-shaped. The bristle-embedded surface 2 is located on one side of the flat end of the toothbrush head 1. The rod-shaped end of the toothbrush head 1 can be fixed as one piece or detachably connected to the toothbrush handle.

[0015] Furthermore, the bristle bundle assembly 3 includes a tooth surface bristle bundle group 31 located in the middle region of the bristle implantation surface 2 and an interdental bristle bundle group 32 located in the top and bottom regions of the bristle implantation surface 2. The bristle bundle hardness of the interdental bristle bundle group 32 is greater than that of the tooth surface bristle bundle group 31. Furthermore, the cross-section of the bristle bundles in the bristle bundle assembly 3 is a regular hexagonal structure; Specifically, compared to traditional circular or elliptical cross-sections, the hexagonal cross-section provides a larger contact area, allowing for more bristles to be distributed per unit area, which effectively improves brushing results. Furthermore, the hexagonal shape has more edges and corners than a circular cross-section, which better conform to the shape of the gaps between teeth during brushing, thereby improving cleaning efficiency.

[0016] Furthermore, the bristle bundles in the bristle bundle assembly 3 are mirror-distributed about the central axis of the toothbrush head 1, and the bristles located on the same side of the central axis of the toothbrush head 1 are equidistantly distributed. Specifically, the mirrored distribution design ensures that the bristles on both sides can evenly contact the tooth surface when cleaning teeth, thus providing a consistent cleaning effect. The equidistant distribution further optimizes the layout of the bristle bundles, ensuring that each bristle bundle can effectively participate in cleaning and avoiding uneven cleaning results caused by bristle bundles that are too dense or too sparse.

[0017] Furthermore, the width of the bristle bundles in the interdental brush bristle bundle group 32 gradually increases from the top or bottom area of ​​the toothbrush head 1 towards the middle area. Specifically, the bristle bundles near the top and bottom of the toothbrush head 1 are arranged narrower, while the bristle bundles near the middle area of ​​the toothbrush head 1 are arranged wider, so that the interdental bristle bundle group 32 has a triangular or semi-circular structure, and the top and bottom areas of the toothbrush head 1 can better clean the edges and corners of the teeth.

[0018] Furthermore, each bristle bundle in the bristle bundle assembly 3 has a free end that is away from the bristle planting surface 2, and adjacent bristle bundles are arranged parallel to each other. Specifically, the direction and position of each bristle bundle are designed to be parallel to each other, forming an orderly arrangement to avoid a decrease in cleaning effect due to mutual interference between bristle bundles. Furthermore, the part of the bristles outside the fixed point of the bristle implantation surface 2 is free, and can move and bend freely so as to better conform to the tooth surface and interdental spaces when brushing.

[0019] Furthermore, the bristle-planting surface 2 is provided with multiple bristle-planting holes, and the bristle bundles in the bristle bundle assembly 3 are inserted into the corresponding bristle-planting holes through copper sheets. Specifically, the bristle planting holes are hexagonal in shape, and the copper sheet is inserted into the bristle planting holes with an interference fit to ensure that the bristle bundles are firmly fixed.

[0020] Furthermore, the copper sheet of each bristle bundle in the bristle bundle assembly 3 is used to bind multiple bristles. Specifically, the copper sheet is in the form of a strip. When the ends of the strip are connected and pressed together, they can be enclosed to form a regular hexagonal structure. This structure contains densely arranged bristles, which allows the bristles to form a regular hexagonal structure, maintaining a good shape during use and better performing its cleaning function.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
