Description

Technical Field

[0001] This utility model relates to the field of toothbrushes, specifically a toothbrush with highly efficient cleaning performance. Background Technology

[0002] In the field of oral care, the toothbrush, as a daily cleaning tool, directly affects its cleaning effectiveness, ease of use, and user experience through its structural design. Traditional toothbrushes generally suffer from the following technical pain points:

[0003] I. Limitations of the cleaning performance of brush bristles

[0004] Most existing toothbrush bristles use a single shape (such as a round tuft), which is insufficient for cleaning complex areas such as between teeth and the gingival sulcus. Round bristles have weak cohesion and rounded tips, making it difficult to reach narrow gaps between teeth to remove food debris and plaque. Long-term use can easily lead to tartar buildup or increased risk of cavities. Furthermore, traditional bristle layouts lack targeted zone design, failing to address the cleaning needs of different areas such as the tooth surface, occlusal surface, and gum line, resulting in lower cleaning efficiency.

[0005] II. Functional defects in the brush head structure

[0006] Hygiene risks associated with non-removable designs: Most toothbrushes have a fixed connection between the brush head and the handle, making it difficult to thoroughly clean the connection between the bottom of the brush head and the handle after use. This damp environment can easily breed bacteria and create unsanitary corners.

[0007] Traditional toothbrushes rely solely on the simple raised or flat structures on the back of the bristles to clean the tongue coating. This results in a small contact area, insufficient friction, and a lack of targeted design that conforms to the physiological curvature of the tongue, leading to limited cleaning effectiveness. Therefore, we have proposed a toothbrush with highly efficient cleaning performance. Utility Model Content

[0008] In view of the shortcomings of the existing technology, this utility model provides a toothbrush with high cleaning performance, which solves the above-mentioned problems.

[0009] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a toothbrush with high cleaning performance, including a grip, the end of which is provided with a detachable brush head, and a bristle area on one side of the brush head; the bristle area includes fan-shaped brush head parts located on the upper and lower sides and several sets of parallelogram brush head parts located in the middle area.

[0010] Preferably, a suction cup is fixedly installed at the end of the gripping part.

[0011] Preferably, the back of the brush head is provided with multiple sets of back rubber parts at equal intervals, and the cross-section of the back rubber parts is triangular.

[0012] Preferably, the end of the gripping part is integrally formed with a plug-in part, and the inside of the brush head is provided with a bolt structure, which is threadedly connected to the plug-in part.

[0013] Preferably, a circular groove is provided at the bottom of the brush head and a circular groove is provided at the top of the brush head. The bolt structure includes a circular part and a threaded rod, and the threaded rod is threadedly connected to the plug part.

[0014] Preferably, the end of the circular portion is provided with a rubber bonding portion.

[0015] Preferably, an inner groove is formed on the inner wall of the circular groove, and a side protrusion is integrally formed on the insertion part corresponding to the position of the inner groove, and the side protrusion is engaged with the inner groove.

[0016] Compared with the prior art, this utility model provides a toothbrush with highly efficient cleaning performance, which has the following beneficial effects:

[0017] Highly efficient cleaning performance: The brush head features a combination of parallelogram and fan-shaped bristles, resulting in strong bristle clusters and pointed tips that effectively reach between teeth. Compared to traditional round bristles, it offers better cleaning guidance, more thoroughly removing food debris and plaque from tooth surfaces, interdental spaces, and gingival sulci, thus improving oral hygiene efficiency. The different bristle shapes are strategically distributed to cover various parts of the teeth, meeting the cleaning needs of different areas such as tooth surfaces, occlusal surfaces, and the gum line.

[0018] Convenient to use and store: The suction cup installed at the end of the grip can be firmly attached to smooth surfaces such as bathroom countertops, making it convenient for users to pick up and store. It prevents the toothbrush from sliding due to water stains on the countertop, solving the problem of unstable placement of traditional toothbrushes. It is especially suitable for special groups such as children and the elderly, improving the convenience of use.

[0019] Multifunctional integrated design: The triangular cross-section rubber part on the back of the brush head conforms to the physiological curvature of the tongue, which can effectively increase the contact area and friction with the tongue. Compared with the simple raised structure of traditional toothbrushes, it can clean the tongue more efficiently, remove bad breath, and realize the integration of brushing teeth and cleaning tongue.

[0020] Reliable detachable connection: The brush head and grip are connected via a plug-in joint and bolt structure, secured by a threaded connection. The inner groove and side protrusions effectively prevent brush head rotation, ensuring stability during use. The rubber seal at the rounded end seals any gaps after connection, preventing foreign objects from entering and avoiding bacterial growth due to moisture. This design facilitates brush head removal and replacement while ensuring the sealing and durability of the connection structure. Attached Figure Description
