[0003] As an innovative form of oral care tools, U-shaped toothbrushes have received widespread attention and application in the field of oral health care, especially in the field of children's oral care in recent years. Its unique design aims to better adapt to the contours of children's mouths through the wrapped brush head structure and effectively clean tooth surfaces and hard-to-reach areas, such as slits between teeth and posterior dental regions, thereby improving brushing efficiency and cleanliness. The existing U-shaped toothbrush improves the comfort, flexibility and fun of children's toothbrushing through innovative structural design, and promotes the development of good oral hygiene habits.

[0004] The existing U-shaped toothbrush usually adopts a brush head made of soft or elastic materials to adapt to the changes in the size and shape of the oral cavity of children of different ages. Fine and soft bristles are embedded in the brush head to clean teeth in a mild way. A handle portion is designed to be easy to hold. Some are also equipped with anti-slip materials or cute cartoon images to increase children's interest in use. The basic structure includes a fixed U-shaped brush head connected to a handle, and the user mainly controls the direction and intensity of brushing manually during use.

[0005] However, although the existing U-shaped toothbrush improves convenient and interest of children's toothbrushing to a certain extent, it still reveals some significant defects during actual use. The design of traditional children's toothbrushes is often single, and the connection between the brush head and the handle is fixed. The fixed angle of the brush head often makes it difficult to ensure that each child can find the most suitable toothbrushing posture, thereby affecting the comfort and effect of toothbrushing. At the same time, it is difficult to adapt to the differences in oral structure and toothbrushing habits of different children, resulting in poor toothbrushing effect or children's resistance to toothbrushing. Although there are some adjustable toothbrushes on the market, most of them have limited adjustment ranges and cannot meet children's diverse needs for the angles of the handle and the brush head during toothbrushing.SUMMARY

[0006] The objective of the present invention is to solve the above defects and provide a 360-degree rotary adjustable U-shaped toothbrush to solve the technical problem of the existing U-shaped toothbrush in the background art that it is difficult to adjust the relative angle between the handle and the brush head during toothbrushing, thereby affecting the comfort and effect of toothbrushing.

The end of the rotating connector 500 forms a “T” shaped insertion portion, and the brush head 100 is paired and inserted into the insertion portion through the insertion slot.

[0053] Specifically, through an adjustment mechanism of the rotating connector 500, children can choose to brush teeth by lifting their hands or lowering their hands or with any other comfortable toothbrushing posture, which can effectively adapt to different oral sizes, shapes and toothbrushing habits, and improve the cleaning efficiency. At the same time, the rotary adjustable process itself has a certain degree of playability, and the adoption of different colored brush heads 100 or decorative members or handles 400 can further stimulate children's interest in toothbrushing and increase the fun.

[0054] Optionally, in some embodiments, the handle 400 is designed into a cartoon image, such as rabbit ears and other shapes, to increase appeal.

[0055] The specific connection structure in this embodiment is:

[0056] The limiting seat 800 is inserted into the accommodating cavity 201. The guide hole 801 of the limiting seat 800 extends toward the sliding groove 203. The sliding groove 203 is composed of a baffle formed in the accommodating cavity 201 by injection molding. The control member 600 is arranged in the accommodating cavity 201 and matched with the sliding groove 203. The control member 600 is sleeved with the spring through the guide post 604 and matched with the guide hole 801, so that the unlocking portion 602 of the control member 600 is exposed. Outside the mounting hole 202, pass one end of the rotating connector 500 through the limiting hole 603 on the control member 600 and butt it with the bottom wall of the accommodating cavity 201, and connect it to the bottom wall through the limiting groove 501 on the rotating connector 500. The locking portion 601 in the limiting hole 603 is clamped and matched, and the shell cover 300 is matched and installed on the shell 200, so that the other end of the rotating connector 500 passes through the through hole 30B and is inserted and matched with the brush head 100;

[0057] in the unlocked state, the unlocking portion 602 is only simply pressed to make the control member 600 slide toward the limiting seat 800 along the sliding groove 203. At this time, the locking portion 601 inside the limiting hole 603 releases the clamping of the limiting groove 501, allowing the angle of the brush head 100 to be easily adjusted to meet the children's needs for diversified angles between the handle 400 and the brush head 100 during toothbrushing, which is simple and fast to operate. When the pressure is released, the spring elastically resets to make the locking portion 601 of the control member 600 re-lock the limiting groove 501 of the rotating connector 500, thereby ensuring the stability and safety of the toothbrush during use.Embodiment 2

[0058] In this embodiment, with reference to FIGS. 7-8, the difference between the second embodiment and the first embodiment is that the handle 400 and the shell 200 are separated, a connection hole is provided at the bottom of the shell 200, and one end of the rotating connector 500 is connected to the handle 400 through the connecting hole, and the other end of the rotating connector 500 is engaged with the inner side of the shell cover 300 through the connecting portion. A protrusion 30A for connecting the brush head 100 is formed on the top of the shell cover 300.

[0059] The top of the shell cover 300 is connected to the brush head 100 through the protrusion 30A. The handle 400 and the shell 200 are separate and movable. The end of the rotating connector 500 extending toward the accommodating cavity 201 is connected to the handle 400 through the connecting hole. The other end of the rotating connector 500 is connected to the inner side of the shell cover 300;

[0060] In the unlocked state, the unlocking portion 602 is only simply pressed to make the control member 600 slide toward the limiting seat 800 along the sliding groove 203. At this time, the locking portion 601 inside the limiting hole 603 releases the clamping of the limiting groove 501, allowing the angle of the handle 400 to be easily adjusted to meet the children's needs for diversified angles between the handle 400 and the brush head 100 during toothbrushing, which is simple and fast to operate. Specially, after the angle of the handle 400 is adjusted, the angle of holding the handle 400 changes, so that the angle of the brush head 100 can be adjusted relative to the handle 400. Or exemplarily, when the handle 400 is held, and the unlocking portion 602 is pressed, since the handle 400 is held and limited, at this time, the shell 200 and the shell cover 300 can be rotationally adjusted, so that the angle of the brush head 100 can be easily adjusted. When pressure is released, the spring elastically resets to make the locking portion 601 of the control member 600 re-lock the limiting groove 501 of the rotating connector 500, thereby ensuring the stability and safety of the toothbrush during use.

[0061] In summary, the problem that the angle of the conventional brush head 100 is fixed is solved through the rotating connector 500, so that the toothbrushing angle of children's toothbrushing angle can be adjusted to be optimal according to the personal oral structure, toothbrushing habits, and comfort level, thereby improving the toothbrushing effect and the comfort level, and the brush head 100 or the handle 400 can be driven to rotate through the rotating connector 500, so that children can personally explore and try different toothbrushing angles during toothbrushing, and this interaction and participation can increase the fan of toothbrushing.

The locking portion 601 in the limiting hole 603 is clamped and matched, and the shell cover 300 is matched and installed on the shell 200, so that the other end of the rotating connector 500 passes through the through hole 30B and is inserted and matched with the brush head 100;

[0057] in the unlocked state, the unlocking portion 602 is only simply pressed to make the control member 600 slide toward the limiting seat 800 along the sliding groove 203. At this time, the locking portion 601 inside the limiting hole 603 releases the clamping of the limiting groove 501, allowing the angle of the brush head 100 to be easily adjusted to meet the children's needs for diversified angles between the handle 400 and the brush head 100 during toothbrushing, which is simple and fast to operate. When the pressure is released, the spring elastically resets to make the locking portion 601 of the control member 600 re-lock the limiting groove 501 of the rotating connector 500, thereby ensuring the stability and safety of the toothbrush during use.Embodiment 2

[0058] In this embodiment, with reference to FIGS. 7-8, the difference between the second embodiment and the first embodiment is that the handle 400 and the shell 200 are separated, a connection hole is provided at the bottom of the shell 200, and one end of the rotating connector 500 is connected to the handle 400 through the connecting hole, and the other end of the rotating connector 500 is engaged with the inner side of the shell cover 300 through the connecting portion. A protrusion 30A for connecting the brush head 100 is formed on the top of the shell cover 300.

[0059] The top of the shell cover 300 is connected to the brush head 100 through the protrusion 30A. The handle 400 and the shell 200 are separate and movable. The end of the rotating connector 500 extending toward the accommodating cavity 201 is connected to the handle 400 through the connecting hole. The other end of the rotating connector 500 is connected to the inner side of the shell cover 300;

[0060] In the unlocked state, the unlocking portion 602 is only simply pressed to make the control member 600 slide toward the limiting seat 800 along the sliding groove 203. At this time, the locking portion 601 inside the limiting hole 603 releases the clamping of the limiting groove 501, allowing the angle of the handle 400 to be easily adjusted to meet the children's needs for diversified angles between the handle 400 and the brush head 100 during toothbrushing, which is simple and fast to operate. Specially, after the angle of the handle 400 is adjusted, the angle of holding the handle 400 changes, so that the angle of the brush head 100 can be adjusted relative to the handle 400. Or exemplarily, when the handle 400 is held, and the unlocking portion 602 is pressed, since the handle 400 is held and limited, at this time, the shell 200 and the shell cover 300 can be rotationally adjusted, so that the angle of the brush head 100 can be easily adjusted. When pressure is released, the spring elastically resets to make the locking portion 601 of the control member 600 re-lock the limiting groove 501 of the rotating connector 500, thereby ensuring the stability and safety of the toothbrush during use.

[0061] In summary, the problem that the angle of the conventional brush head 100 is fixed is solved through the rotating connector 500, so that the toothbrushing angle of children's toothbrushing angle can be adjusted to be optimal according to the personal oral structure, toothbrushing habits, and comfort level, thereby improving the toothbrushing effect and the comfort level, and the brush head 100 or the handle 400 can be driven to rotate through the rotating connector 500, so that children can personally explore and try different toothbrushing angles during toothbrushing, and this interaction and participation can increase the fan of toothbrushing.
