Description

Technical Field

[0001] This utility model relates to a dental instrument, and more particularly to a toothbrush. Background Technology

[0002] With the improvement of people's living standards and increased attention to oral health, people are paying more and more attention to cleaning their teeth. Current toothbrushes use a single, rigid plastic brush head with bristles. Because human teeth are curved, and the brush head is made of rigid plastic, the brush head cannot deform and is a single piece, making it difficult for the brush head to reach deep into the mouth. The brush head cannot fully conform to the curved shape of the teeth, especially the molars, resulting in incomplete cleaning and affecting the efficiency and effectiveness of brushing. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a toothbrush.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] like Figures 1 to 6 The toothbrush shown includes a brush head 1 and a handle 2 connected to each other. The brush head 1 includes at least two brush plate units 101, which are arranged sequentially from top to bottom. Adjacent brush plate units 101 are connected by a connector 102. Each brush plate unit 101 and the connector 102 are made of a deformable material. The included angle at the intersection of the extension lines of two adjacent brush plate units 101 is an obtuse angle. Each brush plate unit 101 is covered with bristles 103.

[0025] In use, the toothbrush of this invention features an obtuse angle at the intersection of the extended lines of adjacent brush plate units 101 connected by a connector 102. This results in an overall arc-shaped brush head, with a fixed bending angle between adjacent brush plate units. This allows the brush head to better conform to the arc-shaped structure of human teeth, especially when cleaning molars. The deformable brush plate units and the overall arc-shaped brush head facilitate a close fit to the tooth surface, allowing the brush head to penetrate deep into the oral cavity for thorough cleaning of the molars, thus improving cleaning efficiency and effectiveness. Both the brush plate units 101 and the connector 102 are made of PP material, ensuring both deformation capability and safety during use. When cleaning teeth, the brush plate units 101 deform according to the curvature of the tooth surface and the brushing force, providing a gentle pressure relief while also better conforming to the teeth, thus improving cleaning comfort and efficiency.

[0026] In a preferred embodiment, the brush head 1 in this application further includes a brush plate sleeve 104, which is fitted onto the outer wall of the brush plate unit 101. The brush plate sleeve 104 protects the brush plate unit 101 and also enhances the overall integrity and structural strength of the multiple brush plate units 101, extending their service life. The brush plate sleeve 104 is made of soft rubber material, which ensures that the brush plate unit can deform while improving the comfort and safety of the toothbrush during use. The brush plate sleeve 104 in this application is made of TPR, silicone, or TPE material to ensure the safety of the brush head during use.

[0027] In a preferred embodiment, the angle α at the intersection of the extended lines of two adjacent brush plate units 101 is 150-179°. The angle at the intersection of the extended lines of two adjacent brush plate units 101 can be adjusted according to user needs to improve the fit between the brush head and the tooth surface, thereby increasing teeth cleaning efficiency. Figure 5 The brush head shown includes two brush plate units with an included angle α of 170° between them. This type of brush head containing two brush plate units can be used to make children's toothbrushes; for example... Figure 6 The brush head shown includes three brush plate units, with an included angle α of 170° between two adjacent brush plate units. This type of brush head containing two or more brush plate units can be used to make adult toothbrushes, and the number of brush plate units 101 can be adjusted as needed.

[0028] The brush plate unit 101 and the connector 102 described in this application are integrally formed, which helps to improve the integrity and structural strength of the brush head; and the thickness of the connector 102 is less than the thickness of the brush plate unit 101, which facilitates the deformation of two adjacent brush plate units 101, improves the flexibility of the brush plate unit 101 during use, and makes it easier for the brush plate unit 101 to fit the tooth surface more closely.

[0029] In a preferred embodiment, the brush handle 2 is provided with a gripping part 3, located 40mm-55mm from the tip of the brush head to the handle, and the gripping part 3 has a hole 4. During use, the gripping part 3 allows users, especially children, to easily grip the brush in the correct position. Users can insert their thumb or index finger into the hole 4, and then grip the handle 2 with their remaining four fingers. This prevents the toothbrush from falling from the user's hand due to insufficient grip strength, especially for children, thus improving the stability of the user's grip and brushing efficiency. Furthermore, the gripping part 3 also helps limit the length of the handle 2 entering the mouth, improving the safety of children using the toothbrush. The diameter of the hole 4 in this application is 18-25mm, which is convenient for matching the size of the index finger of users, especially children; more preferably, the diameter of the hole can be set to 20mm, allowing the index finger to be quickly inserted into the hole 4, improving the stability and efficiency of children's grip on the toothbrush.

[0030] As a preferred embodiment, the outer contour of the gripping part 3 is circular, making the outer contour of the gripping part more rounded, which improves the comfort of children while avoiding injury to children's hands; the gripping part 3 in this application is made of elastic material, which facilitates the deformation of the gripping part 3 and makes it easy to match the insertion of fingers of different thicknesses into the hole 4.

[0031] In a preferred embodiment, the brush handle 2 of this application includes a straight brush handle 201 and a curved brush handle 202 connected to each other. The straight brush handle 201 is connected to the brush head 1, and the curved brush handle 202 protrudes from the side with the gripping part 3 to the other side. The curved brush handle 202 is designed to fit the curvature of a child's grip, improving the stability and comfort of the child's grip on the toothbrush. The straight brush handle 201, curved brush handle 202, and gripping part 3 are integrally molded, improving the structural stability between the curved brush handle and the gripping part. Specifically, the curved brush handle and the gripping part can be integrally injection molded for ease of manufacturing.

[0032] The arc of the curved brush handle 202 in this application is 105-120°, which makes it easy to fit the palm of a child's hand and improve the comfort of the child gripping the curved brush handle; more preferably, the arc of the curved brush handle in this application is 110°, which is more in line with the curve of a child's hand gripping and improves the comfort and stability of gripping.
