Abstract

To provide a toothbrush that allows for accurate and reliable brushing.SOLUTION: A toothbrush of the present invention is structured such that a head 2 and a brush part 3 of the toothbrush 8 are separated, and a brush base part 4 in which the brush part 3 is flocked is slid inside a sliding part 5 formed on the head 2. Specifically, the present invention makes use of a difference between a width of the brush base part 4 associated with movement of a user's hand and a width of the sliding part 5, namely a difference between a moving width of the user's hand and a moving width of the brush base part 4. The head structure 1 enables accurate and reliable brushing of vibrating finely with a small time difference between movement of the hand and movement of the brush base part 4.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a toothbrush head structure in which a brush head slides. [Background technology]

[0002] Currently, periodontal disease is not considered to be a particularly serious lifestyle-related disease, as it is neither painful nor directly life-threatening. However, it is beginning to be recognized as a cause of systemic diseases. It is also widely known that daily brushing of the teeth and regular removal of plaque and tartar by a dentist are essential to preventing periodontal disease.

[0003] First of all, brushing your teeth is a form of oral care that people perform themselves, and it is an important act of holding a toothbrush in your hand to remove dirt from your teeth and massage your gums. In addition, there are several ways to brush your teeth using a toothbrush, depending on the angle and movement of the brush relative to the teeth and gums. The first method is the relatively recommended Charters method, in which the bristles are placed against the teeth at a 45 degree angle and rotated while being vibrated finely. The second method is the Bass method, in which the tip of the brush is placed between the teeth and gums at a 45-degree angle and moved back and forth in quick motions. The third method involves scrubbing by placing the bristles at a 90-degree angle between the teeth and gums and moving them back and forth in quick motions. The fourth method is the roll method, in which the bristles of the toothbrush are placed parallel to the gums and rotated from the gums toward the tips of the teeth. There are also various other brushing methods, such as loosely inserting the bristles and vibrating them, moving the bristles in a circular motion, and the toothpick method in which the bristles are inserted between the teeth and gums. On the other hand, electric toothbrushes that utilize the vibration and rotational motion of the brush and ultrasonic toothbrushes that use ultrasound to break down plaque are also in use.

[0004] However, the brushing method in which the user brushes with their own hands requires a technique that involves moving the brush part in small, rapid movements against the teeth, between the teeth, and on the gums, and vibrating it finely. This is a highly difficult movement that requires delicate skill on the part of the user, and there is a significant discrepancy between the ideal brushing method and the actual brushing that is performed on a daily basis. On the other hand, brushing with electric or ultrasonic toothbrushes has been criticized for having the drawbacks of over-grinding the teeth and damaging the gums due to the high-performance vibrations and rotation, and users are required to adjust the pressure on the teeth and gums, making it a delicate method of brushing that requires skill from the user. To address this issue, electric toothbrushes have been improved to include built-in sensors and be managed by an app, but the economic viability of this has come into question. On the other hand, for manual toothbrushes, improvements have been made to the size of the brush head, the arrangement of the brushes, and the use of ultra-fine bristles, but the structure and usage of the toothbrush has not changed at present. The bottom line is that people are not brushing their teeth properly today, as evidenced by the prevalence of tooth decay and periodontal disease.

[0005] This is the subject of a proposal in Japanese Patent Laid-Open Publication No. 2000-116438. This proposal seeks to solve the problem by having the grip of the toothbrush and the bristles fixing part of the toothbrush body slide, so that the range of movement of the bristles is reduced by only the length of the width of the notch formed in the grip, compared to the range of movement of the hand. In other words, the stopper provided at the bristle tip fixing section of the toothbrush body slides vertically within the grip section and within the range of the notch, resulting in a toothbrush that does not damage the gums.

[0006] Furthermore, there is a proposal in Japanese Patent Application Laid-Open No. 2000-157340. This proposal aims to make the movement of the brush part during tooth brushing gentler and to make the movement of the hand more auxiliary. In other words, the cushioning members at the front and rear of the gripping part attached to the handle rebound against the front and rear balance parts attached to the handle on which the brush is attached, slowing down the movement of the hand and assisting the back and forth movement, thereby achieving a massage action.

[0007] These proposals are improvements from a perspective not seen in conventional toothbrush improvements, and are proposals that aim to solve a basic problem when brushing, focusing on the fact that the range of movement of the toothbrush bristles recommended by dentists does not match the range of movement of the user's hand.

[0008] However, the first proposal has a structure in which the toothbrush body slides inside the notch in the grip, but the force required to slide the long structure in which the brush head and toothbrush are integrated inevitably puts pressure on the teeth and gums. In other words, unfortunately, there is no solution to the biggest problem when brushing teeth, which is the pressure on the teeth and gums caused by the user's hands.

[0009] However, the second proposal has a structure aimed at moving the toothbrush back and forth by utilizing the rebound force of the cushion member, but in order to obtain the rebound force of the cushion member, it is necessary to press the toothbrush hard and move it, which inevitably puts pressure on the teeth and gums. In other words, unfortunately, there is no solution to the biggest problem when brushing teeth, which is the pressure on the teeth and gums caused by the user's hands.

[0010] [Patent Document 1] JP 2000-116438 A [Patent Document 2] JP 2000-157340 A Summary of the Invention [Problem to be solved by the invention]

[0011] Periodontal disease is now recognized as one of the causes of various diseases. Therefore, the removal of plaque by daily brushing with a toothbrush, interdental brush, floss, etc. is recommended as an important preventive measure. On the other hand, brushing teeth with a toothbrush only removes about 50% of plaque, confirming the importance of regular removal of tartar by a dentist. Therefore, the importance of daily tooth brushing, using a toothbrush and making sure to brush teeth carefully and properly, has been pointed out and praised in order to remove plaque. However, the brushing method, which involves small, wiggly movements of the brush and fine vibrations, is a complex and difficult movement that requires skill, and special training is required from an early age to be able to perform the hand movements reliably. In other words, the way people typically brush their teeth involves sliding the toothbrush over a relatively large area and pressing the toothbrush against them, which can result in damage to the teeth and gums due to the pressure from the brush, and inaccurate brushing does not achieve the full effect of brushing and can actually cause damage. In addition, the problem of pressure on the teeth and gums caused by the brushing parts of the toothbrush is a common issue shared by those who brush their teeth with electric toothbrushes.

[0012] The object of the present invention is to provide a toothbrush structure that improves the efficiency of brushing when a user uses a toothbrush to brush their teeth, and that eliminates the problem of pressure on the teeth and gums when brushing. In other words, the objective is to provide a toothbrush structure that is gentle on the teeth and gums and that enables the user to perform an accurate and reliable brushing method by moving the brush part in small, quick movements and fine vibrations. [Means for solving the problem]

[0013] The present invention provides a head structure (1) for sliding a brush part (3) formed on a head part (2) of a toothbrush (8), The brush part (3) has bristles planted in a brush base part (4), The head structure (1) is composed of the head (2) and the brush base (4), The head structure (1) is formed by separately forming the head (2) and the brush base (4), The head portion (2) forms a slide portion (5) having a function of storing and holding the brush base portion (4), The brush base (4) is disposed on the inner side of the slide portion (5), The brush base (4) is configured to slide on the inner portion of the slide portion (5), The slide portion (5) forms an opening (6) through which the brush portion (3) moves, The slide portion (5) has a space (7) formed in an inner portion thereof, The space (7) is formed between the brush base (4) and the slide portion (5), The brush base (4) is configured to move in the space (7), The space (7) forms a gap (7a) penetrating the head (2) from the space (7), The slide portion (5) forms the space portion (7) in the longitudinal direction of the toothbrush (8), The slide portion (5) is characterized in that the brush base portion (4) slides in the longitudinal direction of the toothbrush (8).

[0014] In the present invention, the sliding portion (5) forms the space portion (7) in the short side direction of the toothbrush (8), The slide portion (5) is characterized in that the brush base portion (4) slides in the lateral direction of the toothbrush (8).

[0015] In the present invention, the sliding portion (5) forms the space portion (7) in the longitudinal direction of the toothbrush (8), The slide portion (5) forms the space portion (7) in the short side direction of the toothbrush (8), The slide portion (5) is characterized in that the brush base portion (4) slides in the longitudinal direction and the lateral direction of the toothbrush (8).

[0016] In the present invention, the sliding portion (5) forms the space portion (7) in the longitudinal direction of the toothbrush (8), The slide portion (5) forms the space portion (7) in the short side direction of the toothbrush (8), The slide portion (5) forms the space portion (7) in the thickness direction of the toothbrush (8), The slide portion (5) is characterized in that the brush base portion (4) slides in the longitudinal direction, lateral direction, and thickness direction of the toothbrush (8). Effect of the Invention

[0017] The first effect of the present invention is that the toothbrush is formed by separating the brush part from the head, the brush part is attached to the brush base, and the brush base can be slid relative to the head, thereby making it possible to reduce the range of movement of the brush part compared to the range of hand movement when brushing teeth. In other words, the range of movement of the brush part is smaller than the range of movement of the user's hand when brushing, thereby achieving the small, wiggly movements and fine vibrations required for accurate and delicate brushing. Furthermore, the structure for sliding the brush base is designed so that if the brush part is pressed too hard against the teeth or gums, the brush base will not slide smoothly, resulting in accurate and delicate brushing that does not damage the teeth or gums.

[0018] The second effect of the present invention is that, because the brush part can be slid in the lengthwise, widthwise, and thicknesswise directions of the toothbrush, it is possible to provide a large number of toothbrushes having a variety of brush parts that can accommodate the various brushing methods of users.

[0019] The third effect of the present invention is that the brush part can be freely slid in the lengthwise, widthwise and thicknesswise directions of the toothbrush, thereby providing a brush part that prevents excessive pressure on the teeth and gums, particularly when applied to an electric toothbrush.

[0020] The fourth advantage of the present invention is that the structure of the toothbrush head and the brush base part on which the head and brush part are attached can be replaced, reducing consumption of the neck and handle parts of the toothbrush, thereby addressing environmental issues.

[0021] The fifth effect of the present invention is that it provides a new structure that is an improvement to the brush part of a toothbrush, providing a new variety of toothbrush options, thereby revitalizing the toothbrush market and further realizing the oral health of users.

[0024] First, an example of a head structure 1 and a toothbrush 8 according to the present invention will be shown and described with reference to FIG. FIG. 1 shows an example of a toothbrush 8 and a brush base 4 of a head structure 1. FIG.

[0025] Next, a toothbrush 8 shown in FIG. 1 is an example that is composed of a head portion 2, a neck portion 9, and a handle portion 10. Moreover, the toothbrush 8 shown in FIG. 1 is an example in which a sliding portion 5 is formed on the head 2, a brush base portion 4 having a brush portion 3 attached thereto is disposed on the sliding portion 5, and a void portion 7a is formed which penetrates the head 2 from a space portion 7 formed in the sliding portion 5. Moreover, the toothbrush 8 shown in FIG. 1 illustrates an example in which a brush base portion is placed on the head portion 2 in advance. Furthermore, the toothbrush 8 shown in FIG. 1 shows an example in which a head connecting portion 11 formed on the head 2 and a neck connecting portion 12 formed on the neck 9 are detachably connected to form the toothbrush 8; however, the connecting means is not specified or limited, and a suitable means can naturally be selected and adopted from among known connecting means. This shows an example in which economic benefits can be achieved by reusing the neck 9 and handle 10 of the toothbrush 8, and further shows an example in which it also contributes to environmental issues.

[0026] Next, the toothbrush 8 shown in Figure 1 is configured so that the head 2 is connected to the neck 9 and handle 10, but it may also be configured so that they are not connected, and the head 2, neck 9 and handle 10 may be formed as a single unit, the slide portion 5 of the present invention may be formed in the head 2 of the toothbrush 8, the brush base 4 may be disposed inside, and the brush base 4 may be freely attached and detached from the slide portion 5, and this is not limited to any particular configuration. Furthermore, the head structure 1 of the toothbrush 8 of the present invention shown in FIG. 1 is characterized in that a slide portion 5 formed on the head 2 slides the brush base portion 4, and is not specific to or limited to the configuration of this embodiment. An embodiment of the head structure 1 of the present invention will be described below. EXAMPLES

[0027] Next, referring to FIG. 2, the brush base 4 of the head structure 1 according to the first embodiment is aligned in the longitudinal direction of the toothbrush 8. We will explain this by showing an example of sliding. FIG. 2-1 is a schematic cross-sectional view of an example of the head structure 1 in the longitudinal direction of the toothbrush 8, showing a roughly central portion thereof. FIG. 2-2 is a schematic cross-sectional view of an example of the head structure 1 in the short side direction of the toothbrush 8, showing a roughly central portion thereof.

[0028] Next, the head structure 1 according to the first embodiment will be described with reference to FIG. In addition, the head structure 1 shown in Figure 2 shows an example in which the brush base portion 4, which is placed on the inner part of the slide portion 5 formed in the head 2, is configured to slide the slide portion 5 in the longitudinal direction of the toothbrush 8. In addition, the head structure 1 shown in Figure 2 shows an example in which the brush base portion 4 is arranged on the inner part of the sliding portion 5, and space portions 7 are formed on both sides of the brush base portion 4 in the longitudinal direction of the toothbrush 8, and shows an example in which the brush base portion 4 is configured to slide in the space portions 7.

[0029] Next, the head structure 1 shown in Figure 2-1 shows an example in which the brush base portion 4 slides through the space portions 7 formed on both sides of the toothbrush 8 in the longitudinal direction, and the brush base portion 4 slides in the longitudinal direction of the toothbrush 8. Moreover, the head structure 1 shown in FIG. 2-2 is a structure in which the brush base 4 does not form a space 7 in the lateral direction of the toothbrush 8, and shows an example of a configuration in which the toothbrush does not slide in the lateral direction. Moreover, the head structure 1 shown in Figs. 2-1 and 2-2 is a structure in which the brush base portion 4 does not form a space portion 7 in the thickness direction of the toothbrush 8, and shows an example of a configuration in which the toothbrush does not slide in the thickness direction.

[0030] Next, the head structure 1 shown in FIG. 2 shows an example of a structure in which the brush base part 4 slides in the longitudinal direction of the toothbrush 8. In other words, the head structure 1 shown in FIG. 2 is a structure that corresponds to the Bass method, which is a brushing method in which the head portion of the brush unit 3 is moved in small movements in the longitudinal direction of the toothbrush 8 at a 45 degree angle to the teeth and gums, but is not specific or limited to this structure, and since the movement of the brush unit 3 is smaller than the movement of the user's hand, small movements are achieved.Furthermore, the head structure 1 shown in FIG. 2 is also suitably adapted to the scrubbing method in which the head portion of the brush unit 3 is moved at a 90 degree angle to the teeth and gums.

[0031] Next, the brush part 3 shown in Figure 2 has bristles attached to the brush base part 4, and is configured so that the brush part 3 comes into contact with the teeth and gums when brushing, and slides together with the brush base part 4. For example, the way the brush part 3 shown in Figure 1 moves is that the user moves the toothbrush 8, and the brush base part 4 moves together with the brush part 3 which is in contact with the teeth and gums, and when the brush base part 4 comes into contact with the sliding part 5, the toothbrush 8 is moved in the reverse direction, repeating the brushing motion. The feature of the present invention is that a space 7 is formed between the brush base portion 4 and the sliding portion 5 when the brush base portion 4 abuts the sliding portion, so that when a user moves the toothbrush 8, the difference in the width of movement between the brush base portion 4 and the sliding portion 5 is utilized. In other words, the width of movement of the brush head 3 is narrower than the width of the toothbrush 8 moved by the user, thereby enabling quick brushing. Furthermore, a feature of the present invention is that the brush base portion 4 is configured to abut and slide against the sliding portion, and in this case, if the brush portion 3 is pressed hard against the teeth or gums, the brush base portion 4 naturally becomes less likely to slide. This makes it possible to prevent the brush portion 3 from being pressed hard when brushing, thereby preventing damage to the teeth and gums. Moreover, the brush portion 3 shown in FIG. 2 is naturally made of a known material, and is not limited to any particular material. In addition, the brush part 3 shown in Figure 2 is an example in which the bristles are planted on the brush base part 4, and are formed in five rows in the longitudinal direction and three rows in the transverse direction of the toothbrush 8, but the number and position are not specified or limited, and the present invention shows an example in which the bristles are planted on the brush base part 4 and the brush base part 4 slides. In addition, the brush portion 3 shown in FIG. 2 is naturally selected from known specifications such as the material, length, hardness, number of bristles, and number of bristle bundles of the brush portion 3, and is not specified or limited here. In addition, the brush part 3 shown in Figure 2 is configured to slide together with the brush base part 4 when it slides, and an opening 6 that does not hinder the movement of the brush part 3 at that time is formed in advance in the sliding part 5.

[0032] Next, the brush base portion 4 shown in Figure 2 is the part on which the brush part 3 is attached, and shows an example configured to be placed on a sliding portion 5 formed on the head part 2, characterized in that the brush base portion 4 is configured to slide along with the movement of the brush part 3 that is in contact with the teeth and gums during brushing. In addition, the brush base portion 4 shown in Figure 2 shows an example in which it is pre-positioned on the inner part of the slide portion 5 formed on the head portion 2, but this is not specific or limited to this, and it is natural that it may be formed into a structure that is easily detachable from the slide portion 5. In other words, the brush base 4 shown in FIG. 2 is configured to slide on the inner part of the sliding part 5, but it goes without saying that suitable known technologies, such as materials, are selected and adopted to make the brush base 4 and the sliding part 5 easy to slide, and this is not specified or limited here. In addition, the thickness and width of the brush base 4 shown in Figure 2 are selected and configured from a variety of factors, such as the brush part 3 to which the bristles are attached and the function and shape of the head 2 used, and are not specified or limited here. Furthermore, the shape of the brush base portion 4 shown in Figure 2 is placed on the sliding portion 5 formed on the head 2 of the toothbrush 8, and it is natural that it is formed in a shape that conforms to the shape of the sliding portion 5, and it is natural that it is configured on the premise of a brush portion 3 that is compatible with a variety of toothbrushes 8, and is not specified or limited here. In addition, the material of the brush base 4 shown in Figure 2 may or may not be made of the same material as the toothbrush 8, and is not specified or limited, and it is natural that specifications that make it difficult to slide the slide portion 5 formed on the head 2 should be avoided.

[0033] Next, the slide portion 5 shown in FIG. 2 is an example that is formed on the head portion 2 and has a function of storing and holding the brush base portion 4. In addition, the slide portion 5 shown in Figure 2 is formed into a structure that stores, arranges, and holds the brush base portion 4, and the specifications can naturally be suitably selected from known means, and are not specified or limited here. Furthermore, the slide portion 5 shown in FIG. 2 naturally has a structure and strength that allows the brush base portion 4 to slide and not fall off, and naturally employs suitable materials and specifications selected from well-known technologies, and is not specified or limited here.

[0034] Next, the opening 6 shown in Figure 2 shows an example in which the brush part 3 is planted on the brush base part 4 and is formed as the part through which the brush part 3 slides when the brush base part 4 slides. Furthermore, the opening 6 shown in Figure 2 is naturally formed taking into consideration the sliding width when the brush base 4 slides and the bristles width of the brush part 3, and is not specified or limited here. Furthermore, the opening 6 shown in Figure 2 is characterized in that the head structure 1 of the present invention slides the brush base portion 4 formed on the slide portion 5, and the dimensions of the opening 6 formed are determined by the specifications of the brush base portion 4 and the brush portion 3 which can accommodate a variety of brushing methods, and are not specified or limited here.

[0035] Next, the space 7 shown in FIG. 2 is an example characterized in that it is formed as a portion that provides a width for the brush base 4 to slide. 2 is characterized in that the brush base 4 slides on the inner side of the sliding portion 5. As shown in FIG. Furthermore, the space 7 shown in FIG. 2 is formed as a means for sliding the sliding portion 5 in the longitudinal direction of the toothbrush 8, and is naturally configured to accommodate the various hand movements of the user, and is not specified or limited here. In addition, the volume of the space 7 shown in Figure 2 corresponds to the width of movement of the brush base 4 when it slides, and the volume is not specified or limited here; it corresponds to different hand movements of the user in advance, and the volume of the sliding part determines the width of movement of the brush base 4, so it is natural that a selection can be made from a number of different volumes and is not specified or limited here.

[0036] Next, the void portion 7a shown in FIG. 2 is formed in the head portion 2 and has a structure penetrating the head portion 2 from the space portion 7, and an example is shown in which four void portions are formed, but the size, shape, number, position, etc. are not specified or limited. In addition, the gap 7a shown in Figure 2 is configured between the slide portion 5 and the brush base portion 4 to allow impurities such as water, toothpaste, saliva, food debris, flaked plaque, and tartar to be expelled when brushing. In addition, the gap 7a shown in FIG. 2 is naturally formed and configured so as not to affect the sliding of the brush base 4, and a suitable known technology may be adopted for the shape, number, etc., and is not specified or limited here. In addition, the gap 7a shown in Figure 2 may be designed and formed by high-density design of the slide portion 5 and the brush base portion 4, and a variable valve structure for the gap 7 may be adopted as a measure against the air in the space portion 7 being compressed during sliding.It is not specified or limited to a penetrating gap 7a or valve structure, and it is natural that any known technology that does not interfere with the sliding of the brush base portion 4 may be adopted. EXAMPLES

[0037] Next, referring to FIG. 3, the brush base 4 of the head structure 1 according to the second embodiment is in the lateral direction of the toothbrush 8. We will explain this by showing an example of sliding. FIG. 3-1 is a schematic cross-sectional view of a roughly central portion showing an example of the toothbrush 8 in the longitudinal direction of the head structure 1 according to the second embodiment. FIG. 3-2 is a schematic cross-sectional view of an example of the head structure 1 in the short side direction of the toothbrush 8, showing a roughly central portion thereof.

[0038] Next, the head structure 1 according to the second embodiment will be described with reference to FIG. Moreover, the head structure 1 shown in Figure 3 shows an example in which the brush base portion 4, which is arranged on the inner part of the sliding portion 5 formed in the head 2, is configured to slide the sliding portion 5 in the short direction of the toothbrush 8. In addition, the head structure 1 shown in Figure 3 shows an example in which the brush base portion 4 is arranged on the inner part of the sliding portion 5, and space portions 7 are formed on both sides of the brush base portion 4 in the short direction of the toothbrush 8, and shows an example in which the brush base portion 4 is configured to slide in the space portions 7.

[0039] Next, the head structure 1 shown in FIG. 3-1 is a structure in which the brush base 4 does not form a space 7 in the longitudinal direction of the toothbrush 8, and shows an example of a configuration in which the toothbrush does not slide in the longitudinal direction. In addition, the head structure 1 shown in Figure 3-2 shows an example in which the brush base portion 4 slides through the space portions 7 formed on both sides of the short side of the toothbrush 8, and the brush base portion 4 slides in the short side direction of the toothbrush 8. Moreover, the head structure 1 shown in Figures 3-1 and 3-2 is a structure in which the brush base portion 4 does not form a space portion 7 in the thickness direction of the toothbrush 8, and shows an example of a configuration in which the toothbrush does not slide in the thickness direction.

[0040] Next, the head structure 1 shown in FIG. 3 shows an example of a structure in which the brush base part 4 slides in the lateral direction of the toothbrush 8. In other words, the head structure 1 shown in FIG. 3 is a structure corresponding to the Chaws method, which is a brushing method in which the head part of the brush unit 3 is brought into contact with the teeth at a 45-degree angle and rotated while vibrating finely from the teeth to the gums, but is not specific or limited to this structure, and since the movement of the brush unit 3 is smaller than the movement of the user's hand, it realizes small, wiggly movements.
