New description: [New technical field] This work is about a toothbrush, especially a toothbrush for the prevention of periodontal disease. [Prior Art] Periodontal disease and tooth decay are two common diseases in the oral cavity. The attack rate of Chinese people is as high as 90% or more. The periodontal disease is caused by the inaccurate cleaning of teeth, which makes bacteria in the teeth and gums. The plaque is formed to form plaque, and if the tartar is not removed at this time, the accumulation of tartar will cause the gums to shrink and form a periodontal pocket. At this time, the food residue is likely to accumulate in the periodontal period. The capsular bag is not easy to remove, which causes inflammation of the gums, which further damages the periodontal tissues such as the gums, periodontal ligaments, and alveolar bones, and eventually causes the teeth to loosen or even fall off. Therefore, the first step in the prevention and treatment of periodontal disease is to brush your teeth frequently, especially the correct brushing. It is not only necessary to clean the tooth body, interdental teeth, but also the cleaning of the periodontal sulcus between the teeth and the gums. However, currently available toothbrushes have a wide range of toothbrushes designed for different purposes and functions. However, there are few specially designed toothbrushes for cleaning periodontal sulcus, so there is no special prevention for periodontal disease. help. The so-called "workers must first sharpen their tools when they want to do something good". A toothbrush that can effectively clean the periodontal fangs will have a "do more with less" effect on the prevention of periodontal disease. In view of the fact that the existing toothbrush design can not provide effective periodontal sulcus cleaning function, the inventor of the professional dentist has developed a kind of tooth cleaning tooth in addition to the general toothbrush cleaning experience after years of 硏M435862 research and combined with his own professional dental medical knowledge. In addition to the efficacy of the body and interdental teeth, it can effectively clean the periodontal sulcus to achieve a toothbrush that prevents periodontal disease. [New content] The purpose of this creation is to provide a toothbrush that can simultaneously provide the function of preventing the periodontal disease by simultaneously providing the tooth body and interdental tooth cleaning function and effectively cleaning the periodontal sulcus function. The above object of the present invention can be attained by a periodontal disease preventing toothbrush comprising: a toothbrush handle; a long toothbrush head formed at one end of the toothbrush handle; and a plurality of toothbrush heads disposed on the toothbrush head a bristles on a surface, wherein the bristles comprise: a first set of bristles disposed longitudinally along a central longitudinal axis of the brush head and having a first height, a second set of bristles longitudinally along the toothbrush The two sides of the head are disposed and have a second height lower than the first height, and a third set of bristles disposed longitudinally between the first set of bristles and the second set of bristles and having a lower The first height is higher than the third height of the second height. According to an embodiment of the present invention, the first set of bristles comprises very fine tapered bristles, and the second set and the third set of bristles comprise rounded bristles. Preferably, the first height differs from the third height About 3mm. In addition, the sides of the toothbrush handle each include a beveled configuration at an angle of 45 degrees to facilitate attachment of the bristles to the tooth surface at 45 degrees during use. Other features and advantages of the present invention will become apparent from the following detailed description of the appended claims. -4- M435862 [Embodiment] The present invention provides a periodontal disease prevention toothbrush 1 according to the embodiment shown in FIG. 1 to FIG. 4, wherein FIG. 1 is a top plan view of the periodontal disease prevention toothbrush 1 of the present invention. 2 is a side view of the periodontal disease prevention toothbrush 1 of the present invention, FIG. 3 is an end view of the periodontal disease prevention toothbrush 1 of the present invention, and FIG. 4 is a schematic end view showing the use state of the periodontal disease prevention toothbrush 1 of the present invention. . φ As shown in FIG. 1 to 4, the present periodontal disease prevention toothbrush 1 mainly comprises a toothbrush handle 10, an elongated toothbrush head 12 formed at one end of the toothbrush handle 1 and a plurality of toothbrush heads disposed thereon. The bristles 20 on a surface of 12. The toothbrush handle 1 has a beveled configuration of 18 degrees on both sides of the handle body. As shown, the bristles 20 include a first set of bristles 22 disposed longitudinally along a central longitudinal axis of the head 12 and having a first height Η1, a second set of bristles 24, longitudinally along The two sides of the toothbrush head 12 are disposed and have a second height Η2 lower than the first height Η1, and a third group of bristles 26 longitudinally disposed on the first group of bristles 22 and the second Between the set of bristles 24 and having a third height Η3 lower than the first height Η 1 but higher than the second height Η 2, ie Η 2 < Η 3 < Η 1, so that the arrangement of the bristles is formed in the toothbrush head in the end view The bristles at the center of the 1 2 are the highest and gradually become smaller toward the sides of the brush head 12 into a spire design, as shown in Figure 3. In addition, since the healthy gums and teeth (i.e., periodontal sulcus) have a depth of about 3 mm, the height of the first set of bristles 22 (i.e., Η1) and the height of the third set of bristles 26 (g卩, The height difference between H3) is preferably about 2-4 mm to facilitate penetration of the first set of bristles 22 into the periodontal sulcus for -5-M435862 cleaning. In a preferred embodiment, the first height HI is about 13 mm, the three heights H3 are about 10 mm, and the second height H2 is about 8 mm. In this embodiment, the type of first set of bristles 22 is different than the type of second bristles 24 and third set of bristles 26. For example, the first set of bristles is preferably a very thin, tapered bristles (as shown in the portion of circle A of Figure 3), whereby the longest first set of bristles 22 can be more easily accessed into the periodontal sulcus. The more accurate sulcus cleaning is carried out, while the second set of bristles and the third set of bristles 26 are round-headed bristles (as shown in the enlarged view of the circle B and the circle in Fig. 3), to the tooth surface and the tooth gap. clean. In use, the user can naturally approach the toothbrush head at an angle of about 45 degrees when brushing the teeth through the aid of the beveled configuration of the upper side of the toothbrush handle 10 to form a 45, so that the bristles 20 can The angle shown in the figure is attached to the teeth for brushing. At this point, as shown in Figure 4, the longest first set of bristles 22 are naturally closest to the teeth and gum joints (i.e., periodontal sulcus), and since the first set of bristles 22 are composed of thin pointed bristles Therefore, it can be easily penetrated into the periodontal sulcus for cleaning, thereby achieving an effective periodontal disease prevention effect. In addition, the shorter second and third sets of bristles 24, 26, which are comprised of rounded hairs, are also capable of cleaning the teeth while the long first set of bristles 22 are cleaning the periodontal sulcus. In other words, the toothbrush of the present invention can perform a positive cleaning action on the periodontal sulcus and the tooth surface at the same time, and at the same time, the double effect of tooth cleaning and periodontal prevention, which is a kind of tooth cleaning and periodontal. Novel creation of disease prevention effects. Although the present invention for the periodontal disease prevention toothbrush 1 has been described above with reference to the preferred embodiment shown in the accompanying group 22, the 24 C degree 12 4 phase cleaning brush, the clear figure -6-M435862 is shown. This does not mean that the present invention is limited only to the structures and features described above and shown in the drawings. In fact, the present invention may be variously modified and varied under the principles and spirit of the teachings disclosed above. For example, as shown in Fig. 5, in another embodiment according to the present invention, the bristle configuration of the periodontal disease preventing toothbrush 1' is different from the bristle configuration of the embodiment described above. In detail, in the embodiment shown in FIG. 5, the bristles also include a first set of bristles 22', a second set of bristles 24' φ and a third set of bristles 26' and the relative relationship between the three sets of bristles is also The foregoing embodiment is the same, and differs from the embodiment described above in that the front, middle and rear sections of the first set of bristles 22' have a higher bristle height, and the bristle height during the period is lower, thereby forming a wavy shape. In addition, the heights of the second set of bristles 24' and the third set of bristles 26' also have a height variation corresponding to the first set of bristles 22', thus forming the bristles configuration shown in FIG. In addition to cleaning the periodontal sulcus and flank, this bristle configuration enhances the cleaning of the interdental seam. # All of these and other possible modifications and variations are within the true scope of the present invention as defined by the scope of the claims below.
