Description

A toothbrush with an adjustable brush head angle Technical Field

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

[0002] In the field of oral care, people are increasingly demanding higher functionality and better user experience from toothbrushes. Micro-adjustable toothbrushes are a new type of oral cleaning tool that allows for flexible adjustment of the brush head angle during use. As people place greater emphasis on oral health, traditional fixed-angle toothbrushes can no longer meet diverse cleaning needs. For example, different areas inside the mouth, such as molars and interdental spaces, require different cleaning angles. A toothbrush with a flexible adjustable angle can better conform to the tooth surface, thoroughly clean every corner, effectively remove plaque, prevent cavities and periodontal disease, improve oral hygiene, and meet the needs of refined oral care.

[0003] Traditional toothbrush technology has several shortcomings. First, the fixed-angle brush head makes it difficult to precisely reach complex areas of the mouth, easily creating blind spots and leading to poor oral hygiene with long-term use. Second, due to the inability to adjust the angle, traditional toothbrushes have poor bristle-to-tooth contact during use, resulting in low cleaning efficiency and potential damage to gums due to improper force, affecting oral health. Furthermore, traditional toothbrushes have limited storage options and lack convenient organization, taking up space and easily breeding bacteria, hindering hygiene. These drawbacks significantly limit the user experience and oral care effectiveness. Therefore, we have proposed a toothbrush with an adjustable brush head angle. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a toothbrush with an adjustable brush head angle, thus solving the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a toothbrush with an adjustable brush head angle, including a handle, a connector on one side of the handle, a circular hole at the bottom of the inner wall of the connector, the circular hole extending to the bottom of the connector, a polygonal hole at the top of the connector, the polygonal hole being directly above the circular hole, a brush head at the top of the connector, a turntable fixedly connected to the middle of the outer wall of one side of the brush head, a round head fixedly connected to the outer wall of the turntable away from the brush head, and multiple sets of bristles evenly distributed in a rectangular shape on the outer wall of the brush head away from the turntable.

[0006] Preferably, the outer wall of the turntable is a regular hexagon, the outer wall of the round head is inserted into the inner wall of the round hole, the outer wall of the turntable is fitted with the inner wall of the polygonal hole, and the turntable and the polygonal hole are in a transition fit.

[0007] Preferably, the bottom of the brush handle is provided with a spherical seat, the top of the spherical seat is provided with a slot, and the bottom of the brush handle is inserted into one end of the inner wall of the slot.

[0008] Preferably, the bottom of the spherical base is provided with a suction cup.

[0009] Preferably, the outer wall of the brush handle near the brush head has thumb-pressing grooves, which are multiple sets of equally spaced arc-shaped grooves.

[0010] Preferably, the outer wall of the brush handle away from the thumbprint has a back fingerprint, which is an irregular circular groove in the shape of a fingerprint.

[0011] Preferably, an anti-slip grip silicone pad is fixedly connected to the outer wall of one end of the bottom of the brush handle, and multiple sets of irregular wavy stripes are formed on the outer wall of one end of the anti-slip grip silicone pad.

[0012] Compared with the prior art, this utility model provides a toothbrush with an adjustable brush head angle, which has the following beneficial effects:

[0013] 1. This micro-angle adjustable toothbrush, unlike traditional toothbrushes with a fixed brush head angle, struggles to precisely conform to the tooth surface when cleaning complex areas inside the mouth, such as the inside of molars, around wisdom teeth, and between teeth. This can leave cleaning blind spots, potentially leading to plaque buildup and oral diseases like cavities and periodontitis with long-term use. This device achieves micro-angle adjustment of the brush head through the interaction of round and polygonal holes on the inner wall of the head with the rotating platform and round head of the brush head. Users can flexibly adjust the brush head angle according to the cleaning needs of different parts of the mouth, allowing the bristles to better conform to the tooth surface, thoroughly clean every corner, effectively remove plaque, improve oral hygiene, reduce the risk of oral diseases, and provide users with a more comprehensive and efficient oral cleaning experience.

[0014] 2. This micro-angle adjustable toothbrush differs from traditional toothbrushes, which often have a simpler grip design and lack sufficient consideration for ergonomics. Prolonged use can easily lead to hand fatigue, and the toothbrush may slip during brushing due to an unstable grip, affecting the user experience. This device features several optimizations to the handle. The outer wall near the brush head has thumb-pressing grooves in multiple evenly spaced arc-shaped grooves, conforming to ergonomic design and effectively conforming to the shape of the thumb. The outer wall away from the thumb-pressing grooves has irregular circular grooves resembling fingerprints, providing comfortable pressure points for the other fingers. A non-slip silicone grip pad is also fixedly attached to the bottom outer wall, with irregular wavy stripes on its surface further increasing friction. These designs work together to make the hand grip more natural and stable, effectively preventing the toothbrush from slipping even when hands are wet or sweaty, greatly reducing hand fatigue, and significantly improving the comfort and stability of the grip during brushing.

[0015] 3. This micro-angle adjustable toothbrush addresses the common problem of traditional toothbrushes being placed haphazardly, typically directly on a wash cup or countertop. This not only allows the brush to roll easily and take up space, but also leaves water stains and moisture residue on the brush, fostering bacterial growth and compromising oral hygiene. This device effectively solves these problems through its spherical base and suction cup design. The brush handle inserts into a slot at the top of the spherical base, and the suction cup at the bottom of the base adheres firmly to smooth surfaces such as washbasins and mirrors, allowing the toothbrush to stand stably upright. This saves space and avoids direct contact between the toothbrush and the surface, reducing bacterial growth. This convenient and hygienic placement method makes it easy for users to access and store the toothbrush, helps maintain its cleanliness, and provides stronger protection for oral health.

[0044] Working Principle: First, the basic structure of the toothbrush is established by connecting the handle 1 and the connector 2. The connector 2 is located on one side of the handle 1, providing a basic framework for subsequent component connections. The round hole 3 at the bottom and the polygonal hole 4 at the top of the inner wall of the connector 2 are key structures for adjusting the angle of the brush head 5. The round hole 3 extends to the bottom of the connector 2, and the polygonal hole 4 is located directly above the round hole 3, enabling the connector 2 to accommodate and connect other components. The micro-angle adjustment of the brush head 5 is achieved through the cooperation of the turntable 6 with the polygonal hole 4 and the round head 7 with the round hole 3. The turntable 6 is fixedly connected to the middle of one side of the outer wall of the brush head 5, and the round head 7 is fixedly connected to the outer wall of the turntable 6 away from the brush head 5. The outer wall of the turntable 6 is a regular hexagon, and one end of the outer wall of the round head 7 is inserted into the inner wall of one end of the round hole 3. The outer wall of the turntable 6 and the inner wall of the polygonal hole 4 are fitted together, with a transitional fit between the turntable 6 and the polygonal hole 4. This structure allows the brush head 5 to rotate within a certain range to adapt to different oral cleaning needs. When the angle of the brush head 5 needs to be adjusted, the turntable 6 can rotate within the polygonal hole 4 at a certain angle by manually rotating the brush head 5. Due to the transition fit between the turntable 6 and the polygonal hole 4, the brush head 5 can maintain the corresponding angle after rotation. At the same time, the round head 7 rotates within the round hole 3, providing stable support for the rotation of the turntable 6, making the angle adjustment of the brush head 5 more flexible and stable. The turntable 6 is located in the middle of the brush head 5 to reduce the force between the turntable and the rotating hole during brushing, reducing the probability of the connector 2 breaking and the probability of the turntable 6 slipping out of the polygonal hole 4. The connection between the brush handle 1 and the ball seat 9 achieves convenient toothbrush placement. The bottom of the brush handle 1 has a ball seat 9, and the top of the ball seat 9 has a slot 10. The bottom of the brush handle 1 is inserted into one end of the inner wall of the slot 10. This connection method allows the toothbrush to be placed on the ball seat 9. The suction cup 11 at the bottom of the ball seat 9 can fix the ball seat 9 to a smooth surface, making it convenient for users to put the toothbrush away after use and preventing the toothbrush from rolling or falling. The thumb pressing groove 12, the back finger pressing groove 13, and the anti-slip grip silicone pad 14 are designed to achieve a comfortable and stable grip. The outer wall of the handle 1 near the brush head 5 has a thumb pressing groove 12, which is a set of equidistant arc grooves, conforming to ergonomic design, making it easy for the thumb to press and increasing the comfort of the grip. The outer wall of the handle 1 away from the thumb pressing groove 12 has a back finger pressing groove 13, which is an irregular circular groove in the shape of a fingerprint, providing a comfortable gripping point for other fingers. A non-slip grip silicone pad 14 is fixedly connected to the outer wall of one end of the brush handle 1. The outer wall of one end of the non-slip grip silicone pad 14 has multiple sets of irregular wavy stripes, which further increases the grip friction, making the user more stable when using the toothbrush and less likely to slip.
