Abstract
Description
Technical Field
[0001] This utility model relates to the field of toothbrush technology, specifically to a novel toothbrush. Background Technology
[0002] A toothbrush consists of bristles, a handle, and a brush head. The difference in bristle diameter lies in the fact that coarser bristles are stiffer, while finer bristles are softer. The handle is generally made using a two-stage injection molding process, where thermoplastic resin is coated with a layer of elastomer. The brush head is typically square or diamond-shaped; a square brush head can effectively clean every surface of the teeth. Toothbrushes with any shape of brush head can clean teeth.
[0003] Current toothbrush heads and handles are generally fixed, and the rotation of the brush head depends on the handle. This limits its rotational ability within the mouth, hindering effective cleaning of the oral cavity without leaving any blind spots. Therefore, there is an urgent need to design a new type of toothbrush to solve these problems. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] like Figure 1-6 As shown in the figure, a novel toothbrush provided by this utility model embodiment includes a handle 1, a bend 2 is provided at the top of the handle 1, and a composite functional component 3 is provided at the top of the bend 2; a brush head 4 is provided on one side of the composite functional component 3, and the brush head 4 can be rotated and disassembled at the top of the bend 2 at least through the composite functional component 3; a bristle 5 is provided on the outer wall of one side of the brush head 4, and the bristle 5 is used at least for cleaning the teeth in the oral cavity.
[0028] In this embodiment, a brush handle 1 is included, which is the user's handheld part. A ball head 11 is fixedly provided at the bottom of the brush handle 1. The ball head 11 makes it easier for people to hold the brush handle 1, so that the brush head 4 can be used to rub the teeth in the mouth. A suction cup 12 is installed at the bottom of the ball head 11. The suction cup 12 allows the toothbrush to be attached to the table or cup when not in use, which is convenient for placing the toothbrush. An anti-slip pad 13 is provided on one side of the brush handle 1. The anti-slip pad 13 is located on the front side of the brush handle 1. When people hold the brush handle 1, the thumb side can contact the anti-slip pad 13 to achieve a better grip on the brush handle 1.
[0029] In this embodiment, the top end of the brush handle 1 is provided with a bend 2, and the top end of the bend 2 is provided with a composite functional component 3.
[0030] Specifically, the composite functional component 3 includes a connecting plate 31 integrally formed with the top of the elbow 2. The connecting plate 31 has a central hole 32 inside. The core column 36 and the elastic rings 35 on both sides are inserted into the central hole 32 to connect the brush head 4 to the elbow 2 component. Several annularly distributed limiting grooves 33 are provided on one outer wall of the connecting plate 31. The protrusions 37 are engaged inside the limiting grooves 33 to adjust and limit the angle of the brush head 4. There are four limiting grooves 33.
[0031] Specifically, a fixing plate 34 is provided on one side of the outer wall of the brush head 4. The fixing plate 34 is fixedly installed on the back of the brush head 4. Two symmetrically distributed elastic rings 35 are provided on one side of the outer wall of the fixing plate 34, and a stop plate 38 is provided at the end of the elastic ring 35. A core column 36 located in the middle of the two elastic rings 35 is provided on one side of the outer wall of the fixing plate 34. There is a gap between the elastic rings 35 and the core column 36. The core column 36 has a conical structure. The elastic rings 35 on both sides can converge toward the core column 36 to reduce its diameter and can be inserted into the interior of the central hole 32.
[0032] Specifically, a protrusion 37 located outside the elastic ring 35 is provided on one side of the outer wall of the fixing plate 34. The protrusion 37 is engaged inside the limiting groove 33. The engagement of the protrusion 37 inside the limiting groove 33 at different positions realizes the change and limitation of the angle of the brush head 4.
[0033] In this embodiment, a brush head 4 is provided on one side of the composite functional component 3. The brush head 4 can be rotated and disassembled at least at the top of the elbow 2 via the composite functional component 3.

[0034] In this embodiment, a brush 5 is provided on one side of the outer wall of the brush head 4. The brush 5 is used for cleaning the teeth in the oral cavity. The brush 5 is composed of rectangular bristles 51 located in the middle and circular bristles 52 located on both sides. The use of rectangular bristles 51 and circular bristles 52 improves the cleaning effect on the oral cavity.
[0035] Operating steps: When using the toothbrush, the user can use the composite functional component 3 to install the brush head 4 on the elbow 2. Specifically, the elastic rings 35 on both sides are pressed inward, reducing the diameter of the stop plate 38 and allowing it to pass through the central hole 32. Under the rebound of the elastic rings 35, the stop plate 38 is engaged with the connecting plate 31. At this time, the protrusion 37 is precisely engaged in the corresponding limiting groove 33. When the user needs to adjust the angle of the brush head 4, the brush head 4 can be pulled outward along the elbow 2 by hand, causing the protrusion 37 to disengage from the limiting groove 33. Then, the brush head 4 is rotated to the specified angle, and the brush head 4 is released. The elastic rings 35 return to their elasticity, causing the protrusion 37 to engage again in the corresponding limiting groove 33, thus realizing the quick installation and removal of the brush head 4 on the elbow 2 and the adjustment of the angle of the brush head 4.
[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
