Abstract
Description
Technical Field
[0001] The utility model relates to the field of toothbrushes, and particularly to a toothbrush head and an electric toothbrush. Background Art
[0002] A toothbrush head is an oral care tool for cleaning teeth. It is usually composed of a brush handle and bristles. The brush handle facilitates people's grasping and operation, and the bristles are mostly made of soft but tough materials. By brushing on the tooth surface and between the teeth, food residues, dental plaque, etc. on the teeth can be removed, keeping the oral cavity clean and preventing oral diseases.
[0003] The existing toothbrush heads still have the following problems: The existing toothbrush heads generally have a flat design and cannot well adapt to the different contours of teeth. This requires users to constantly change their brushing techniques when brushing teeth to ensure that all parts of the teeth can be relatively thoroughly cleaned. However, frequently changing techniques not only makes the brushing process cumbersome but also greatly increases the user's fatigue. At the same time, even if users try their best to adjust their techniques, it is difficult to ensure uniform cleaning of teeth every time. There are often situations where some parts are over-cleaned while some parts are under-cleaned, ultimately resulting in poor overall cleaning effect, unable to effectively remove food residues and dental plaque on the teeth, and bringing potential risks to oral health; the ordinary bristle structure is prone to problems such as loosening and deformation under the rapid vibration of an electric toothbrush. First of all, this will affect the cleaning effect because the bristles cannot maintain a stable state to effectively clean the tooth surface and between the teeth. Secondly, the loose and deformed bristles are likely to allow residues to flow into the bristles. When the vibration stops, the residues will accumulate in the bristles. This accumulation of residues further leads to uneven vibration transmission of the bristles, thereby again causing incomplete cleaning of the tooth surface and between the teeth. Moreover, for difficult-to-clean parts such as between the teeth and the gum edges, due to the limitations of their own structures, the bristles of ordinary electric toothbrushes may be difficult to flexibly penetrate, so the cleaning accuracy is poor. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a toothbrush head that increases the effective cleaning surface of teeth and achieves the purpose of comprehensively cleaning teeth.
[0005] The technical solution adopted by the utility model to solve its technical problems is: A toothbrush head includes a brush head body and bristles.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] For the convenience of those skilled in the art to understand, the present utility model will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model. The present utility model will be described in detail below in conjunction with the drawings.
[0025] Example 1
[0026] As Figure 1 shown, the toothbrush head of Example 1 includes a brush head body 1 and bristles 2, and the bristles 2 are inserted into the brushing surface of the brush head body 1.
[0027] The bristles 2 at least include a first-layer bristle body 2a, a second-layer bristle body 2b, and a third-layer bristle body 2c arranged in sequence from outside to inside. The bristle heights of the first-layer bristle body 2a, the second-layer bristle body 2b, and the third-layer bristle body 2c gradually decrease from outside to inside, so as to achieve a comprehensive wrapping of the tooth surface, greatly increasing the effective cleaning surface of the teeth, achieving the purpose of comprehensively cleaning the teeth, and the three-layer bristle body can make the bristles 2 denser, the overall gradient smoother, and better conform to the tooth contour, greatly increasing the effective cleaning surface of the teeth.
[0028] Preferably, as Figure 1 shown, this design is particularly suitable for a "sweeping and vibrating" electric toothbrush, specifically an electric toothbrush including a main body with an output shaft, and the toothbrush head is mounted on the output shaft.
[0029] A brush handle for installing with the base of the "sweeping and vibrating" electric toothbrush can be installed at the lower end of the brush head body 1. In reality, the brush head body 1 and the brush handle are integrally injection-molded.
[0030] The advantages of installing a three-layer bristle body on the "sweeping and vibrating" electric toothbrush are as follows: First, when the electric toothbrush is working, the three-layer bristle body can better withstand and disperse the vibration force, ensuring that the vibration is evenly transmitted to each bristle 2, so as to more effectively clean the tooth surface and interdental spaces. Second, during the "sweeping and vibrating" process, the three-layer bristle body can more flexibly penetrate into various parts of the teeth, especially the difficult-to-clean interdental spaces and the gingival margins, improving the cleaning accuracy. Third, the inverted U-shaped three-layer bristle body is dense and has a smooth gradient, which can adapt to the rapid vibration frequency of the electric toothbrush, and will not reduce the cleaning effect due to excessive looseness. Instead, it can maintain a stable cleaning force during vibration, greatly improving the brushing efficiency.
[0031] Example 2
[0032] The toothbrush head of Example 2 has basically the same structure as that of Example 1, including a brush head body 1 and bristles 2. The bristles 2 include a first layer of bristle body 2a, a second layer of bristle body 2b, and a third layer of bristle body 2c. The difference is that the bristles 2 further include a fourth layer of bristle body located inside the third layer of bristle body, and the bristle height of the fourth layer of bristle body is lower than that of the third layer of bristle body. The addition of the fourth layer of bristle body, on the one hand, further increases the density of the bristles 2, enabling the toothbrush to better contact the tooth surface and interdental spaces during tooth cleaning and improving the cleaning effect. The structure in which the four layers of bristles 2 gradually decrease inward in sequence makes the gradient of the entire bristles 2 more delicate and smooth, and can better fit various complex tooth contours, achieving comprehensive cleaning whether it is the front, side, or occlusal surface of the teeth.
[0033] On the other hand, for an electric toothbrush, the addition of the fourth layer of bristle body can better adapt to the vibration mode of the electric toothbrush. When the electric toothbrush is working, the more layers of bristles 2 can more evenly disperse the vibration force, enhancing the stability and effectiveness of cleaning. At the same time, different layers of bristle bodies 2 can target different degrees of stains and dental calculus for targeted cleaning, improving the brushing efficiency.
[0034] In addition, the fourth layer of bristle body can penetrate deeper into the gum area. During the brushing process, the fourth layer of bristle body can buffer the impact of the vibration of the electric toothbrush on the gums, reducing the risk of gum damage.
[0035] Example 3
[0036] The toothbrush head of Example 3 has basically the same structure as the three-layer bristle body of Example 1 and the four-layer bristle body toothbrush head of Example 2. The difference is that, as Figures 5 - 6 shown, the toothbrush head of Example 3 includes an elastic bristle sleeve 4 for protecting the brush head body 1 and the bristles 2.
[0037] Specifically, as Figures 5 - 6 shown, the elastic bristle sleeve 4 includes auxiliary bristles 4a and a side edge 4b. The side edge 4b is sleeved on the edge of the brush head body 1, and the auxiliary bristles 4a are arranged on the side of the side edge 4b and have the same extending direction as the bristles. The side edge 4b can be made of an elastic material such as silicone, and the auxiliary bristles 4a can also be made of materials such as nylon, pig hair, carbon fiber, or silicone. When selecting the bristles 2, the bristle 2 material can be selected according to one's own oral cavity needs and taste preferences, or the auxiliary bristles 4a and the side edge 4b can be integrally formed using silicone.
[0038] The edge wrapping 4b and the auxiliary bristles 4a have two usage methods. One is that after brushing teeth, the edge wrapping 4b is wrapped around the edge of the brush head body 1, and the auxiliary bristles 4a are wrapped around the outer-layer bristles 2, effectively preventing the bristles 2 from splitting and greatly increasing the service life of the toothbrush. The other is that the edge wrapping 4b is also directly wrapped around the edge of the brush head body 1, and the auxiliary bristles 4a are wrapped around the outermost-layer bristles 2. But at this time, the auxiliary bristles 4a and the bristles 2 clean the teeth together. The addition of the auxiliary bristles 4a increases the cleaning surface area, enabling the toothbrush to more comprehensively cover all parts of the teeth when cleaning the teeth, thus greatly improving the cleaning efficiency and bringing a more efficient and thorough oral cleaning experience to users. Preferably, the height of the auxiliary bristles 4a is not limited and can be set to a suitable height according to the needs of users, providing a more personalized cleaning experience for users.
[0039] Specifically, as Figure 6 shown, anti-slip patterns 4c are provided on the inner walls of the edge wrapping 4b. The setting of the anti-slip patterns 4c facilitates the edge wrapping 4b to firmly fit on the brush head body 1, enhancing the connection tightness between the edge wrapping 4b and the brush head body 1, thereby improving the stability of the fit and ensuring that there will be no loosening or other situations during use, bringing a more reliable use experience to users.
[0040] Embodiment Four
[0041] The toothbrush head of Embodiment Four is basically the same as the three-layer bristle body of Embodiment One and the four-layer bristle body toothbrush head of Embodiment Two. The difference is that, as Figures 5 - 6 shown, the toothbrush head of Embodiment Four includes a groove 5 and a hair implanting sheet 6. The third-layer bristle body or the fourth-layer bristle body is arranged on the hair implanting sheet.
[0042] Preferably, the inner wall of the groove 5 is wavy, and the side surface of the hair implanting sheet 6 is provided with a mating surface that mates with the inner wall of the wavy groove 5. This wavy shape increases the mating area between the hair implanting sheet 6 and the groove 5, thereby improving the installation stability. At the same time, the operation is simple, and the hair implanting sheet 6 can be easily replaced by direct plugging and unplugging. This design makes the toothbrush head more flexible in structure. It is not only convenient to replace the worn hair implanting sheet 6 to extend the service life, but also can arbitrarily select the model of the hair implanting sheet 6 according to the needs of users. Preferably, the third-layer bristle body or the fourth-layer bristle body is arranged on the hair implanting sheet to meet personalized needs.
[0043] Embodiment Five
[0044] The toothbrush head of Embodiment Five is basically the same as the three-layer bristle body of Embodiment One. The difference is that, as Figures 1 - 4As shown, the brush tip ends of the first layer of bristle bodies 2a, the brush tip ends of the second layer of bristle bodies 2b, and the brush tip ends of the third layer of bristle bodies 2c are set to cross the brush opening 3, and the first layer of bristle bodies 2a, the second layer of bristle bodies 2b, and the third layer of bristle bodies 2c are successively vertically and centripetally recessed along the cross brush opening 3.
[0045] The setting of crossing the brush opening 3 facilitates the teeth to bite into the three layers of bristle bodies, enabling the three layers of bristle bodies to fit the tooth contour, greatly increasing the effective cleaning area of the teeth. During the process of cleaning teeth, it ensures that the three layers of bristle bodies can clean the teeth smoothly back and forth without obstruction, thus guaranteeing the high efficiency of cleaning. In addition, the three layers of bristle bodies are vertically and centripetally recessed along the cross brush opening 3, making the three layers of bristle bodies closely fit the tooth contour, and further capable of achieving the purpose of comprehensively cleaning teeth.
[0046] Preferably, as Figure 1 shown, this design is particularly suitable for a "sweeping and vibrating" electric toothbrush, specifically an electric toothbrush including a main body with an output shaft, and the toothbrush head is installed on the output shaft. The setting of crossing the brush opening 3 enables the three layers of bristle bodies to move back and forth more smoothly when the electric toothbrush vibrates, cleaning the teeth without obstruction, and fully exerting the high-efficiency cleaning ability of the "sweeping and vibrating" electric toothbrush. The design that the three layers of bristle bodies are vertically and centripetally recessed along the cross brush opening 3 can, under the vibration of the electric toothbrush, fit the tooth contour more closely, achieving a full wrap of the tooth surface and further improving the cleaning effect. In addition, the brush opening is located in the middle of the three layers of bristle bodies, and this design provides a good channel for the vibration conduction of the "sweeping and vibrating" electric toothbrush, enabling the vibration to be transmitted more evenly to all parts of the three layers of bristle bodies, thereby improving the brushing efficiency.
[0047] The first layer of bristle body 2a is composed of soft bristle bodies, and the soft bristle bodies are used to penetrate deep into parts such as the gums and tooth gaps to make the cleaning more comprehensive and in-depth. The second layer of bristle body 2b is composed of medium bristle bodies, and the medium bristle bodies 3b are used to brush the sides of the teeth. The third layer of bristle body 2c is composed of hard bristle bodies, and the hard bristles are used to brush the occlusal surfaces of the teeth. The settings of the soft bristle bodies, medium bristle bodies, and hard bristle bodies are conducive to respectively adapting to different structures of the teeth.
[0048] The heights of the soft bristle bodies, the medium bristle bodies, and the hard bristle bodies gradually decrease inward in sequence. The soft bristle bodies are the highest, and using pointed filaments, double-pointed filaments, or soft bristles 2 can not only avoid irritating the gums but also effectively clean the tooth gaps. The medium bristle bodies and the hard bristle bodies decrease in height in sequence to clean the crown part of the teeth. The three bristle 2 bodies together form an inverted "U" shape structure to wrap the teeth, so as to improve the brushing efficiency. Different types of bristles 2 correspond to different tooth parts, and better oral cleaning effects can be achieved during cleaning.
[0049] Preferably, as Figures 1 - 4As shown, the height of the soft bristle body is 11 mm, the height of the medium bristle body is 8 mm, and the height of the hard bristle body is 5 mm. Multiple soft bristle bodies, medium bristle bodies, and hard bristle bodies with different heights can also be set, which can make the gradient of the brush bristles 2 denser and smoother, increasing the surface area for cleaning teeth. During the cleaning process, it can more effectively contact the tooth surface, thus significantly improving the effect of cleaning teeth and bringing a better oral cleaning experience to users.
[0050] Specifically, the brush tooth ends of the soft bristle body are rounded. The rounded soft bristle body can effectively reduce the damage to the gums during the cleaning process, play a role in protecting the gums, and further improve the overall cleanliness, bringing a safe and high-quality oral cleaning experience to users.
[0051] The above content is a further detailed description of the present utility model in combination with specific further embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as the protection scope of the present utility model.
