Description

Technical Field

[0001] This utility model relates to the field of toothbrush technology, specifically to a toothbrush with a curved brush head. Background Technology

[0002] A toothbrush is a cleaning product with a handle. It is used to apply toothpaste to the brush and then use the bristles to repeatedly brush all parts of the teeth to maintain oral hygiene.

[0003] Most toothbrushes on the market are currently designed with a single-sided brush. When using them, the user manually rotates the handle to flip the brush inside the mouth to clean different surfaces of the teeth. With a three-sided toothbrush, multiple surfaces of the teeth can be cleaned simultaneously.

[0004] However, most existing three-sided toothbrush heads are difficult to rotate and use, lack flexibility during operation, and usually cannot ensure that the bristles of the three-sided toothbrush make full contact with the teeth, thus having certain defects in use. Therefore, we propose a toothbrush with a curved brush head to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a toothbrush with a curved brush head to solve the problems mentioned in the background art, such as that most existing three-sided toothbrush heads are difficult to rotate and use, have poor flexibility during operation, and are usually inconvenient to ensure that the bristles of the three-sided toothbrush make full contact with the teeth.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a toothbrush with a curved brush head, comprising a handle assembly, the handle assembly including a holding part and a brush head, a connecting block fixedly disposed on the outer end face of the brush head, and a movable connecting unit connected to the outer side of the connecting block, a first brush head assembly fixedly connected to the end face of the movable connecting unit away from the brush head, the first brush head assembly including a first bristle block fixedly disposed on the outer end of the movable connecting unit, a second brush head assembly connected to the outer side of the first bristle block, and the second brush head assembly including a second bristle block symmetrically disposed on the outer side of the first bristle block.

[0007] As a preferred technical solution of this utility model, the brush handle assembly further includes a connecting part, one end of which is fixedly connected to the holding part, and the other end of which is fixedly connected to the brush head. The outer surface of the connecting part is set in a concave arc shape.

[0008] As a preferred embodiment of the present invention, the movable connecting unit further includes a connecting hole opened inside the rubber connecting block, and one side of the connecting hole is connected to an opening opened inside the rubber connecting block.

[0009] As a preferred technical solution of this utility model, the rubber connecting block is rotatably connected to the connecting block through the connecting hole, and the axial sections of both the connecting block and the connecting hole are arranged in a "T" shape.

[0010] As a preferred technical solution of this utility model, the first bristle block is arranged in a "U" shape, and an installation cavity is opened inside the first bristle block. The first brush head assembly also includes a connecting piece movably arranged inside the installation cavity, and the first end face bristles are evenly arranged on one side of the outer surface of the connecting piece.

[0011] As a preferred embodiment of the present invention, the second brush head assembly further includes a connecting rod rotatably connected inside the first bristle block, and the connecting rod is fixedly connected to the top of the second bristle block.

[0012] As a preferred embodiment of the present invention, the second brush head assembly further includes second end face bristles evenly disposed on the end face of the second bristle block near the first end face bristles, and the second bristle block is rotatably connected to the outside of the first bristle block via a connecting rod.

[0013] As a preferred embodiment of the present invention, the second brush head assembly further includes a connecting piece fixedly connected to the outer surface of the connecting rod. The connecting piece is bent and rotatably disposed inside the mounting cavity, with one end of the connecting piece overlapping the top surface of the connecting piece.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the toothbrush with the curved brush head can ensure that the bristles of the three sides of the toothbrush are in full contact with the teeth when in use, resulting in better cleaning of the tooth surface. At the same time, it solves the problem that most existing three-sided toothbrush heads are difficult to rotate and have poor flexibility during operation.

[0015] 1. With the first and second end face bristles positioned on the outer side of the tooth, the tooth can be cleaned on all three sides simultaneously. One end of the connecting piece overlaps with the top surface of the connecting piece. When the first end face bristles contact the tooth end face, the first end face bristles are pressed, causing the connecting piece to move inside the mounting cavity. This causes the connecting piece to touch the connecting piece, which in turn causes the second bristle block to rotate around the axis of the connecting rod via the connecting rod. This causes the second brush head assembly to rotate relative to the first brush head assembly, thereby bringing the second end face bristles closer to the two sides of the tooth. The second end face bristles are in close contact with the pressure surface for cleaning, resulting in a better cleaning effect on the tooth surface.

[0016] 2. A slit is made inside the rubber connecting block through one side of the connecting hole. By opening the slit inside the rubber connecting block, the connecting block and the movable connecting unit can be separated. At the same time, the rubber connecting block and the connecting block form a rotating connection through the connecting hole. The axial sections of both the connecting block and the connecting hole are set in a "T" shape. In use, the movable connecting unit rotates around the connecting block, which makes the first bristle block rotate relative to the brush handle, making it more flexible to use.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a toothbrush with a curved brush head, including a handle assembly 100, the handle assembly 100 including a holding part 101 and a brush head 102, and a connecting block 2 fixedly disposed on the outer end face of the brush head 102, such as... Figure 1 As shown, the brush handle assembly 100 also includes a connecting part 103, one end of which is fixedly connected to the holding part 101, and the other end of which is fixedly connected to the brush head 102. The outer surface of the connecting part 103 is in the shape of a concave arc. Because the outer surface of the brush head 102 is in the shape of a concave arc, when brushing teeth, the connecting part 103 contacts the lips, reducing the pressure and wear on the lips, making it more comfortable to use.

[0025] Combination Figure 4 and Figure 5 As shown, a movable connecting unit 300 is connected to the outer side of the connecting block 2. The first brush head assembly 400 is fixedly connected to the end face of the movable connecting unit 300 away from the brush head 102. The movable connecting unit 300 also includes a connecting hole 302 opened inside the rubber connecting block 301. One side of the connecting hole 302 is connected to an opening 303 opened inside the rubber connecting block 301. By prying open the opening 303 inside the rubber connecting block 301, the connecting block 2 and the movable connecting unit 300 can be separated, thereby separating the first brush head assembly 400 from the brush handle assembly 100. At the same time, the rubber connecting block 301 forms a rotatable connection with the connecting block 2 through the connecting hole 302. The axial sections of both the connecting block 2 and the connecting hole 302 are T-shaped. In use, the movable connecting unit 300 can rotate around the connecting block 2, so that the first brush head assembly 400 can rotate relative to the brush handle assembly 100, making it more flexible to use.

[0026] Specific examples Figure 2 and Figure 4 As shown, the first brush head assembly 400 includes a first bristle block 401 fixedly disposed at the outer end of the movable connecting unit 300. A second brush head assembly 500 is connected to the outer side of the first bristle block 401. The second brush head assembly 500 includes second bristle blocks 501 symmetrically disposed on the outer side of the first bristle block 401, as shown in the figure. Figure 1 and Figure 4 As shown, the first bristle block 401 is U-shaped and has an internal mounting cavity 402. The first brush head assembly 400 also includes a connecting piece 403 movably disposed inside the mounting cavity 402. The connecting piece 403 has a first end face bristle 404 evenly disposed on one side of its outer surface. The second brush head assembly 500 also includes a second end face bristle 504 evenly disposed on the end face of the second bristle block 501 near the first end face bristle 404. With the first end face bristle 404 and the second end face bristle 504 disposed on the outer side of the teeth, the teeth can be cleaned on all three sides at the same time when brushing.

[0027] Specific examples Figure 2 and Figure 3As shown, the second brush head assembly 500 further includes a connecting rod 502 rotatably connected inside the first bristle block 401, and the connecting rod 502 is fixedly connected to the top of the second bristle block 501. The second bristle block 501 is rotatably connected to the outside of the first bristle block 401 through the connecting rod 502. The second brush head assembly 500 also includes a connecting piece 503 fixedly connected to the outer surface of the connecting rod 502. The connecting piece 503 is bent and is disposed inside the mounting cavity 402. One end of the connecting piece 503 overlaps the top surface of the connecting piece 403, and the connecting piece 503 plays a transmission role.

[0028] like Figure 2 As shown, when the first end face bristles 404 contact the tip of the tooth, the first end face bristles 404 are squeezed, which in turn drives the connecting piece 403 to move towards the connecting piece 503 side inside the mounting cavity 402. The connecting piece 403 touches the connecting piece 503, causing the connecting piece 503 to rotate relative to the connecting rod 502 inside the mounting cavity 402. This, in turn, drives the second bristle block 501 to rotate inward around the axis of the connecting rod 502 outside the first bristle block 401. The second brush head assembly 500 rotates relative to the first brush head assembly 400 towards the first end face bristles 404 side, thereby causing the second end face bristles 504 to move closer to the two sides of the tooth, and cleaning is performed by the second end face bristles 504 adhering to the tooth surface.

[0029] The working principle of this invention is as follows: When using this toothbrush with a curved brush head, first hold the holding part 101, then insert the brush head 102 into the mouth. The connecting part 103 contacts the lips, reducing pressure and wear on the lips, making it more comfortable to use. Specifically, as follows... Figure 1 and Figure 3 As shown, since one end of the connecting piece 503 overlaps the top surface of the connecting piece 403, when the first end face bristles 404 contact the tooth end face, the first end face bristles 404 are pressed and drive the connecting piece 403 to move inside the mounting cavity 402, thereby causing the connecting piece 403 to touch the connecting piece 503. The connecting piece 503 drives the second bristle block 501 to rotate around the axis of the connecting rod 502 through the connecting rod 502, thereby causing the second brush head assembly 500 to rotate relative to the first brush head assembly 400, so that the second end face bristles 504 move closer to the two sides of the tooth and clean the tooth surface by adhering to the tooth surface. With the first end face bristles 404 and the second end face bristles 504 on the outer side of the tooth, the three sides of the tooth can be cleaned at the same time.

[0030] like Figure 4 and Figure 5As shown, a movable connecting unit 300 is rotatably connected to the outside of the connecting block 2. In use, the movable connecting unit 300 can rotate around the connecting block 2, which allows the first brush head assembly 400 to rotate relative to the brush handle assembly 100, making it more flexible to use. By opening the slit 303 inside the rubber connecting block 301, the connecting block 2 and the movable connecting unit 300 can be separated, thereby separating the first brush head assembly 400 from the brush handle assembly 100. The first brush head assembly 400 or the brush handle assembly 100 can be replaced according to usage requirements.

[0031] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
