Description

Technical Field

[0001] The invention relates to the field of toothbrushes, in particular to a 360-degree rotating adjustable U-shaped toothbrush. Background Art

[0002] As an innovative form of oral care tool, the U-shaped toothbrush has received extensive 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 oral cavity through a wrapped brush head structure, effectively clean the tooth surface and hard-to-reach areas such as the gaps between teeth and the back teeth, thereby improving brushing efficiency and cleanliness. The existing U-shaped toothbrush improves the comfort, flexibility and fun of children's brushing through innovative structural design, and promotes the formation of good oral hygiene habits.

[0003] Existing U-shaped toothbrushes usually use soft or elastic materials to make the brush head to adapt to the size and shape of the mouth of children of different ages. The brush head is embedded with soft bristles to clean the teeth in a gentle way. The handle 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 using it. The basic structure includes a fixed U-shaped brush head connected to the handle. During use, the user mainly controls the direction and strength of brushing teeth manually.

[0004] However, although the existing U-shaped toothbrushes have improved the convenience and fun of children's toothbrushing to a certain extent, some significant defects are still exposed in actual use. Traditional children's toothbrushes are often of a single design, with a fixed connection between the brush head and the handle. The fixed brush head angle often makes it difficult to ensure that every child can find the most suitable brushing posture for themselves, thus affecting the comfort and effect of brushing. At the same time, it is difficult to adapt to the differences in oral structures and brushing habits of different children, resulting in poor brushing effects or children's resistance to brushing. Although there are some adjustable toothbrushes on the market, most of them have a limited adjustment range and cannot meet the diverse needs of children for the handle and brush head angle during brushing. Summary of the invention

[0005] The purpose of the present invention is to solve the above defects and provide a 360-degree rotating adjustable U-shaped toothbrush to solve the technical problem that the relative angle between the handle and the brush head is difficult to adjust during brushing, thereby affecting the comfort and effect of brushing.

[0006] The object of the present invention is achieved in the following ways:

[0020] Optionally, by connecting the rotating connecting piece to the handle and pressing the control piece, the locking part can release the rotating connecting piece, thereby driving the handle to rotate through the rotating connecting piece, releasing the control piece so that the locking part and the limit groove are locked, and the relative angle between the brush head and the handle can be quickly adjusted.

[0021] Optionally, when holding the handle, the control part is pressed, and the handle is manually fixed, and its shell drives the brush head to rotate as a whole, so that the relative angle between the brush head and the handle can be quickly adjusted.

[0022] Further in the above description, a protective cover is detachably inserted on the shell cover, and a cavity for covering the brush head is formed in the protective cover.

[0023] In the above description, the limiting grooves are distributed at intervals on the outer surface of the rotating connector, and a positioning part for matching the rotating connector is formed in the accommodating cavity. The positioning part is used to match and insert the rotating connector, so that the rotating connector can rotate stably, improving the stability and reliability of the connection.

[0024] The beneficial effects of the present invention are as follows: the rotating connecting piece is provided so that the brush head or the handle can rotate relative to the housing, thereby solving the problem of the fixed angle of the traditional brush head, so that children can adjust to the best brushing angle according to their personal oral structure, brushing habits and comfort, thereby improving the brushing effect and comfort. The locking part and the unlocking part designed on the control part, and the reset part matched therewith, constitute a rotation adjustment structure;

[0025] In the unlocked state, the angle of the brush head or handle can be easily adjusted by simply applying pressure to the unlocking part, which meets the children's diverse needs for the handle and brush head angles during brushing. The operation is simple and quick. When the pressure is released, the reset part causes the locking part of the control part to re-lock the rotating connection part to ensure the stability and safety of the toothbrush during use.

[0053] Specifically, through the adjustment mechanism of the rotating connector 500, children can choose to brush their teeth with their hands raised, brush their teeth with their hands lowered, or any other comfortable brushing posture, effectively adapting to different oral sizes, shapes, and brushing habits, and improving cleaning efficiency. At the same time, the rotation adjustment process itself has a certain degree of playfulness, and the use of different colored brush heads 100 or decorative pieces or handles 400 further stimulates children's interest in brushing their teeth and enhances the fun.

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

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

[0056] Insert the limit seat 800 into the accommodating cavity 201, and the guide hole 801 of the limit seat 800 extends to the slide groove 203. The slide groove 203 is composed of a baffle formed by injection molding in the accommodating cavity 201. The control member 600 is arranged in the accommodating cavity 201 and is installed in pair with the slide groove 203. The control member 600 is connected with the spring through the guide column 604 and is matched with the guide hole 801, so that the unlocking portion 602 of the control member 600 is exposed outside the installation hole 202, and one end of the rotating connecting member 500 passes through the limit hole 603 on the control member 600 and docks with the bottom wall of the accommodating cavity 201, and the limit groove 501 on the rotating connecting member 500 is clamped and matched with the locking portion 601 in the limit hole 603, and the shell cover 300 is installed on the shell 200, so that the other end of the rotating connecting member 500 passes through the through hole 30B and is plugged and assembled with the brush head 100;

[0057] In the unlocked state, one only needs to simply press the unlocking portion 602 to make the control member 600 slide along the slide groove 203 toward the limiting seat 800. At this time, the locking portion 601 in the limiting hole 603 releases the clamping of the limiting groove 501, and the angle of the brush head 100 can be easily adjusted, which can meet the children's diverse needs for the angles of the handle 400 and the brush head 100 during brushing. At the same time, the operation is simple and quick. When the pressure is released, the spring elastically resets the locking portion 601 of the control member 600 to re-lock the limiting groove 501 of the rotating connector 500, thereby ensuring the stability and safety of the toothbrush during use.

[0058] Embodiment 2:

[0059] In this embodiment, refer to Figure 7-Figure 8 The difference between the second embodiment and the first embodiment is that the handle 400 and the shell 200 are separately arranged, a connecting hole is opened at the bottom of the shell 200, one end of the rotating connecting member 500 passes through the connecting hole to be connected to the handle 400, and the other end of the rotating connecting member 500 is clamped with the inner side surface of the shell cover 300 through the connecting part, and a protrusion 30A for connecting the brush head 100 is formed on the top of the shell cover 300.

[0060] 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 to the accommodating cavity 201 passes through the connecting hole to connect with the handle 400, and the other end of the rotating connector 500 is clamped and connected with the inner side of the shell cover 300;

[0061] In the unlocked state, the unlocking portion 602 is simply pressed to make the control member 600 slide along the slide groove 203 toward the limiting seat 800. At this time, the locking portion 601 in the limiting hole 603 releases the clamping of the limiting groove 501, and the angle of the handle 400 can be easily adjusted, which meets the diversified needs of children for the angles of the handle 400 and the brush head 100 during brushing. At the same time, the operation is simple and fast. Specifically, after adjusting the angle of the handle 400, the angle of holding the handle 400 changes, and the angle of the brush head 100 can be adjusted relative to the handle 400. Or, for example, when holding the handle 400 and pressing the unlocking portion 602, the handle 400 is held and limited. At this time, the shell 200 and the shell cover 300 can be rotated and adjusted, so that the angle of the brush head 100 can be easily adjusted. When the pressure is released, the spring elastically resets the locking portion 601 of the control member 600 to re-lock the limiting groove 501 of the rotating connector 500, thereby ensuring the stability and safety of the toothbrush during use.

[0062] In summary, the problem of fixed angle of the traditional brush head 100 is solved by the rotating connector 500, so that children can adjust to the best brushing angle according to their personal oral structure, brushing habits and comfort, thereby improving the brushing effect and comfort. The rotating connector 500 can drive the rotation of the brush head 100 or the handle 400, so that children can personally explore and try different brushing angles during the brushing process. This interactivity and sense of participation can increase the fun of brushing.
