Description

Technical Field:

[0001] This utility model relates to an oral hygiene dental tool, specifically to a toothbrush with a "Q"-shaped combined structure for all-round cleaning of teeth. Background technology:

[0002] Dental health is an important symbol of human civilization, and maintaining clean teeth and fresh breath is key to maintaining a good personal image. Dentists recommend brushing your teeth within 30 minutes after each meal, brushing for at least 3 minutes each time, and brushing three times a day using the "3-3-3" brushing method to reduce plaque buildup and prevent various gum health problems. Dentists also suggest brushing in the direction of tooth growth, not by forcefully pulling back and forth horizontally. The areas that should be cleaned during brushing are the three surfaces of the teeth: the outer surface (labial and buccal), the inner surface (palatal and lingual), and the occlusal surface. This ensures thorough cleaning of the teeth while avoiding damage to the gums.

[0003] Currently, the most commonly used toothbrush is a straight-line design where the brush head and handle are integrated into one piece. This type of toothbrush has the following problems:

[0004] The first problem with the toothbrush mentioned above is that the straight-line design creates an angle between the brush head and the teeth at any point in the mouth due to the U-shaped arrangement of the teeth. Only a portion of the bristles of the brush head come into contact with the teeth, making it impossible to achieve full-range contact of the bristles for efficient and comprehensive cleaning.

[0005] The second problem with the aforementioned toothbrushes is that while existing straight-line toothbrushes with integrated brush heads and handles can easily clean the occlusal surfaces and outer surfaces of the incisors, canines, and premolars, they struggle to clean the inner surfaces of these teeth, as well as the areas deep within the mouth where the second and third molars are in close contact with the cheek muscles. Furthermore, food debris tends to accumulate more easily in the lower teeth and on the hidden and exposed surfaces created by variations in tooth curvature and size. Existing straight-line toothbrushes with integrated brush heads and handles not only make cleaning difficult but also prevent thorough cleaning. Failure to clean these areas promptly can easily lead to tartar buildup, affecting gum health and causing periodontal disease.

[0006] The third problem with the toothbrushes mentioned above is that straight toothbrushes are more suitable for brushing horizontally back and forth on the teeth. However, brushing up and down along the direction of tooth growth feels awkward, which greatly reduces the brushing experience and can easily damage the gums, making it easier to develop unhealthy brushing habits.

[0007] The fourth problem with the toothbrushes mentioned above is that their use is limited and their appearance is prominent. They must be stored and used in specific places such as bathrooms and toilets, which would be unsuitable and unsightly to use in other places. In addition, their large size makes them inconvenient to use and carry when going out for social occasions or when there is an urgent need to clean teeth and remove bad breath.

[0008] The fifth problem with the toothbrushes mentioned above is that, during use, the user applies varying pressure to the teeth, and the angle between the brush head and the teeth changes constantly. This makes it impossible to maintain a stable pressure and angle that is beneficial to the teeth. As a result, this usage habit can damage the gums of some teeth that are frequently subjected to high pressure due to habitual angles.

[0009] The sixth problem with the aforementioned toothbrush is that after brushing, the bristles of this straight, one-piece toothbrush cannot fully contact the teeth, resulting in an angle. Furthermore, this toothbrush structure cannot thoroughly clean the inner surfaces of the teeth, causing users to worry about whether their teeth are not cleaned properly. They will habitually need to use a mirror or other tools to check the cleaning effect. Therefore, the existing toothbrush can only be used in places such as bathrooms with mirrors, which greatly limits the choice of brushing location. Summary of the Invention:

[0010] Technical issues

[0011] The main objective of this invention is to provide a toothbrush with a "Q"-shaped combined structure. This "Q"-shaped structure allows all the bristles of the toothbrush head to contact the occlusal surface and sides of the teeth and clean them in the direction of tooth growth. At the same time, the soft toothbrush neck can change its angle according to changes in the oral cavity and tooth shape, ensuring that the brush head always makes appropriate and comprehensive contact with the teeth, achieving all-round cleaning. Furthermore, this structure can consistently and stably maintain an optimal brushing force, achieving scientific and healthy teeth cleaning.

[0012] Technical solution

[0013] To solve the above-mentioned technical problems, this utility model provides a toothbrush with a "Q"-shaped combined structure, comprising:

[0014] The toothbrush head consists of two horizontally arranged cylindrical bristles with openings, and the ends of the cylindrical bristles have teeth.

[0015] A toothbrush handle is a tube with a through hole along its length.

[0016] The toothbrush neck is an elastic strip that connects the toothbrush head and the toothbrush handle.

[0017] An elastic strip is used to connect the toothbrush head and the toothbrush handle. The elastic strip also has scale markings to record the magnitude of the resultant force between the two cylindrical bristles of the toothbrush head.

[0018] A cylindrical toothed brush has teeth at both ends. When brushing, the teeth rotate the brush by biting down, which helps to remove food debris from between teeth, improving cleaning effectiveness and user experience.

[0019] The "Q"-shaped toothbrush head assembly structure, formed by connecting two cylindrical brushes with an elastic strip, allows the bristles to fully contact the occlusal surface and sides of the teeth during the cleaning process.

[0020] Beneficial effects

[0021] The aforementioned "Q"-shaped combination toothbrush head structure is designed to address the distribution characteristics of the oral cavity's dental arch and exposed tooth surfaces, allowing the bristles to make full contact with the tooth surface and clean all exposed surfaces simultaneously. This not only easily achieves thorough cleaning without blind spots but also significantly saves brushing time. According to usage tests, each brushing session, at a biting speed of once per second, takes approximately 19 seconds to clean all teeth. This brushing time does not include repetitive cleaning actions on any particular tooth due to habit.

[0022] The combined structure of the cylindrical bristles of the toothbrush head and the toothed structure at both ends of the bristles of this utility model form a healthy brushing method that combines brushing up and down along the growth direction of the teeth and brushing in a rotating manner under the biting action of the teeth, greatly improving the experience and enjoyment of brushing teeth.

[0023] The present invention allows users to adjust the combined force between the two cylindrical bristles of the brush head by dragging the elastic strip inside the tubular toothbrush handle, thus finding the most suitable brushing pressure for the user. It can maintain the optimal brushing pressure consistently and stably, without any disorderly changes in pressure, achieving scientific, healthy and stable teeth cleaning and providing better protection for teeth.

[0024] The above-mentioned utility model is small in size and easy to carry. It can be used in any situation, even when face to face with others, to clean the mouth and teeth elegantly. It plays a key role in dealing with unexpected situations in social situations where it is necessary to clean teeth and remove bad breath, and greatly improves personal image.

[0025] The present invention allows for brushing teeth without the need for hand intervention, requiring only the assistance of cheek and tongue muscles. Therefore, it can clean teeth while also exercising oral muscles.

[0026] The present invention, through the opening structure of the cylindrical brush, allows for easy insertion or removal of the elastic strip, making it convenient to replace the toothbrush head and handle. This enables personalized combinations of different colors for the toothbrush, thus improving the enjoyment of brushing.

[0027] The present invention can use the I, II, III grade scale symbols on the elastic strip to remember the most suitable brushing pressure for the user, making healthy brushing more intuitive and convenient.

[0028] The present invention can be made into different sizes to suit a wider range of people, based on the different age groups of children and adults and the differences in oral cavity size. Attached image description:

[0039] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] Example 1: As Figures 1 to 4The toothbrush shown is a "Q"-shaped combined toothed structure, including: 1. a toothbrush head; 2. a toothbrush handle; 3. a toothbrush neck; 4. an elastic strip; 5. graduation symbols; 6. the toothbrush head consists of two horizontally arranged cylindrical brushes with openings, each cylindrical brush having teeth at both ends; 7. the toothbrush handle is a tube with through holes along its length; 8. the toothbrush neck is an elastic strip connecting the toothbrush head and the toothbrush handle; 9. the elastic strip connects the toothbrush head and the toothbrush handle, and has graduation symbols to record the magnitude of the resultant force between the two cylindrical brushes of the toothbrush head.

[0041] like Figures 1 to 3 As shown, the toothbrush head consists of two horizontally arranged cylindrical brushes 1 and 2 with openings 7 and 8. The ends of the cylindrical brushes 1 and 2 have teeth 1a, 1b, 1c, 1d, 1e, 1f, 2a, 2b, 2c, 2d, 2e, and 2f. An elastic strip 3 connects the toothbrush head and handle 4 in a "Q"-shaped structure through the openings 7 and 8 of the cylindrical brushes 1 and 2. The toothbrush neck 5 is composed of a flexible elastic strip, allowing the toothbrush head and handle to maintain a straight line. Figure 1 It can also present various angles. Figure 2 , Figure 3 By dragging the lower end of the elastic strip 3, the elastic strip drag point 6 can be adjusted to change the combined force between the two cylindrical bristles 1 and 2 of the toothbrush head to obtain the best and healthiest user experience.

[0042] Example 2: Obtain the optimal force level for your toothbrush head, such as... Figure 1 , Figure 4 As shown, place the toothbrush head on the chewing surface of your teeth. As you bite down, the two cylindrical bristles 1 and 2 of the toothbrush head will gradually separate to the sides due to the elasticity of the elastic strip 3 until the bristles are in close contact with the sides of your teeth. By repeatedly biting down, feel whether the force between the two cylindrical bristles 1 and 2 is comfortable. Adjust the force between the two cylindrical bristles 1 and 2 to the most suitable level by repeatedly biting down and dragging the elastic strip 3 at the drag point 6 inside the toothbrush handle 4. Then, remember this most suitable force level by using the elastic strip force level scale on the elastic strip for future use.

[0043] Example 3: Figure 1 , Figure 4As shown, check if the force level on the elastic strip 3 is at the most suitable level for you. Then, place the toothbrush head on the chewing surface of your teeth. With the help of your cheek and tongue muscles, you can move the toothbrush head to the third molar or any other chewing surface deep in your mouth to begin cleaning. Under the pressure of the chewing action, the two horizontally arranged cylindrical brushes 1 and 2 will separate to the sides. The soft and elastic bristles 9 and 10 of the cylindrical brushes 1 and 2 will sequentially touch the chewing surface and sides of the teeth under the pressure of the force and the teeth. During the chewing action, the chewing surface and sides of the teeth will simultaneously touch the teeth 1a, 1b, 1c, 1d, 1e, 1f, and 2a at the upper and lower ends of the cylindrical brushes 1 and 2 in sequence. Steps 2b, 2c, 2d, 2e, and 2f propel the cylindrical brushes 1 and 2 to rotate, allowing the brushes to clean teeth through both linear and rotary cleaning. For the hard-to-reach areas deep in the mouth, such as the sides of the second and third molars, simply use the cheek and tongue muscles to push the brush head to the occlusal surface of the third molars, coordinating with the biting motion to easily clean the area. Because the toothbrush can clean both sides and the occlusal surface of the teeth simultaneously from back to front, the brushing time is very short. Based on the user's experience of one second per biting motion, the entire brushing process only takes about 19 seconds to complete a thorough cleaning of the teeth. This brushing time does not include other habitual repetitive cleaning actions on a particular tooth.
