[0026] 作为刷毛的材质,没有特别限制,可使用牙刷的刷毛中通常所使用的。 [0026] As the material of the bristles is not particularly limited, and may use a toothbrush bristles generally used. 可举例如, 6-12尼龙、以及6-10尼龙等的聚氨酯、PET、聚对苯二甲酸丁二醇酯(PBT)、聚对苯二甲酸丙二醇酯(PTT)、聚萘二甲酸乙二醇酯(PEN)以及聚萘二甲酸丁二醇酯(PBN)等聚酯,PP等聚烯烃,以及烯烃系弹性体,以及苯乙烯系弹性体等树脂材料。 As can be exemplified, nylon 6-12, nylon 6-10, etc., and polyurethane, PET, polyethylene terephthalate, polybutylene terephthalate (PBT), polyethylene terephthalate (the PTT), poly (ethylene naphthalate) ester resin material (PEN) and polybutylene terephthalate polyethylene naphthalate (PBN) and other polyesters, PP and other polyolefins, and olefin-based elastomer, and styrene elastomer. 这些树脂材料可以单独使用1种, 也可以2种以上并用。 These resin materials may be used alone, or two or more kinds.

[0027] 刷毛的横截面形状优选圆形。 [0027] Preferably the bristles of a circular cross-sectional shape. 此外,刷毛的截面形状并不限于圆形,也可以是例如椭圆形、多边形(例如三角形、四边形、五边形或六边形等)或者特殊形状(例如星形、三叶草形或者四叶草形)等。 Further, the sectional shape of the bristles is not limited to circular, for example, may be elliptical, polygonal (e.g., triangular, quadrangular, pentagonal or hexagonal, etc.) or special shapes (e.g., star-shaped, clover-shaped or clover shape )Wait. 形成第1毛束16a的刷毛的数量,可考虑刷毛直径和刷毛粗细适当选择。 Number 16a forming the first tufts of bristles, the bristles can be considered appropriately selected diameter and thickness of the bristles. 例如,第1实施方式中,优选20~28根,更优选22~28根。 For example, in the first embodiment, preferably 20 to 28, more preferably from 22 to 28. 第1毛束16a中,考虑使用感、刷扫感、清洁效果或者耐久性等,可将粗细不同的多根刷毛任意组合使用。 The first tuft 16a, in consideration of the use of flu, flu sweeping brush, and other cleaning effect or durability may be of different thickness plurality of bristles in any combination.

[0028]第1毛束群16中的毛束16a间的最短距离,即从毛束16a的中心轴到相邻的毛束16a 的中心轴的距离,在群内最短处优选1.4~2.8mm,更优选1.7~2.5mm。 [0028] The shortest distance between 16a, the distance from the central axis of the central axis 16a of the tufts tufts 16a adjacent to the first group of 16 tuft tufts, preferably at the shortest in the group 1.4 ~ 2.8mm , more preferably 1.7 ~ 2.5mm.

[0029][第2毛束群] 第2毛束群18在头部12的植毛面12a上,夹住第1毛束群16,在头部12的前端13侧和后端侧设置一对。 [0029] [2 tufts group] group of second tufts 18 on the head of the anchoring surface 12a 12, sandwiching the first group of tufts 16, 13 in front of the head side and the rear side 12 of a pair . 一对第2毛束群18相互分离。 A pair of second tufts 18 are separated from each group. 也就是说,形成一对第2毛束群18的第2毛束18a, 并非被设置为围住第1毛束群16的宽度方向的两侧,而是被设置为围住其长度方向的两侧。 That is, a pair of the second group of bristle tufts 18a 18 2, not surrounded on both sides is set as a first group of tufts 16 in the width direction, but is provided to surround the longitudinal direction thereof both sides. 如此一来,通过不将第2毛束18a设置为围住第1毛束群16的宽度方向的两侧,使得一对第2毛束群18中,各第2毛束18a的毛端容易进入牙间和牙颈部等的空隙。 Thus, not by the second tufts 18a disposed to surround the sides of the first group of tufts 16 in the width direction, such that a pair of the second group of tufts 18, each of the second tuft 18a Yi Mao Duanrong into the gap between the teeth and tooth neck and the like. 其结果是,由于第2 毛束群18,牙间和牙颈部等的空隙中存在的牙垢可被高效扫出并除去。 As a result, due to the gap of the second group of tufts 18, between the teeth and the tooth neck or the like in the presence of tartar can be efficiently swept out and removed. 形成第2毛束群18的第2毛束18a,也可被植入头部12的植毛面12a的中央区域。 Forming the second group of tufts 18 of second tufts 18a, it may be implanted in the head of the anchoring surface of the central region 12a 12.

[0030] 第2毛束群18是通过植入多根第二毛束18a而形成的,那些多根第2毛束18a的刷毛长度,被对齐于比第1毛束群16更高的刷毛长度。 [0030] The second group of tufts 18 is formed by implanting a plurality of second tufts 18a is formed, and those of the second plurality of tufts of bristles length 18a is aligned with the group than the first tufts of bristles 16 higher length. 据此,第1毛束群16和第2毛束群18的边界部分形成了高度差。 Accordingly, the first group of tufts 16 and second tufts of the cluster boundary portion 18 is formed a height difference. 通过第1毛束群16和第2毛束群18形成高度差,可高效扫出牙间和牙颈部等的空隙中存在的牙垢,因而牙垢除去效果提高。 Height difference is formed by the first group of tufts 16 and the second group of tufts 18 can be efficiently swept out of the gap between the teeth and the tooth neck or the like in the presence of plaque, tartar and thus improve the removal effect.

[0031] 第2毛束群18是以敞开植毛面12a的中央方向,将第1毛束群16在长度方向上围住的样子排列各个第2毛束18a而形成的。 [0031] The second group of tufts 18 are open tufting surface 12a of the central direction, the first group of tufts 16 in the longitudinal direction are arranged to surround the way each of the second tufts 18a formed. 具体地,本例中,第2毛束群18是以敞开植毛面12a的中央方向,将第1毛束群16在长度方向上围住的样子,被设置为俯视呈V字状。 Specifically, in this case, the second group of tufts 18 is a central direction of the open anchoring surface 12a of the first group of tufts 16 in the longitudinal direction surrounded by the way, a plan is set in a V-shape. 此处,"敞开中央方向"的意思是,第2毛束群18并非被设置为相对宽度方向平行(沿宽度方向直线设置), 且第2毛束群18中,配置于植毛面的宽度方向的两端的毛束18a被配置于,比配置于中央的毛束18a更接近中央区域的中心的位置。 Here, "open center direction" means that the second bristle group 18 is not being set to the opposite widthwise parallel (along the width direction of the line set), and the second tuft groups 18 disposed in the width direction of the tufting surface the ends of the tufts 18a is disposed, than in its central bristles 18a at a position closer the center of the central region. 具体意思是,从侧面观察头部12时,存在第1毛束群16和第2毛束群18在长度方向上不重叠的区域,和第1毛束群16和第2毛束群18在长度方向上重叠的区域。 Specifically means, viewed from the side of the head 12, the presence of the first group of tufts 16 and the second group of tufts 18 in the longitudinal direction of the non-overlapping regions, and the first group of tufts 16 and second tufts 18 in the group area overlapping the longitudinal direction. 从侧面观察头部12时,第1毛束群16和第2毛束群18在长度方向上重叠的区域的宽度,在每1个所述区域上优选〇.〇~3.0mm。 Observed width of the head 12, the first group of tufts 16 and the second group of tufts 18 in the longitudinal direction of the overlap region from the side, preferably 〇.〇 - in every one of the region 3.0mm. 此外,本例中,V字状的第2毛束群18的角度(V字状的内角),与第1毛束群16的菱形中的第2毛束群18侧的两条边所形成的角度不同。 In addition, in this case, the second group of tufts V-shaped angle of 18 (V-shaped inner corner), with the first group of diamond tufts 16 in the second group of tufts 18 side of the two sides formed different angles. 此外,V字状的第2毛束群18的角度,与第1毛束群16的菱形中的第2毛束群18侧的两条边所形成的角度也可以相同。 Additionally, the second group of tufts V-shaped angle 18, the angle of the first group of tufts 16 in the diamond-shaped tufts of the second group 18 side of the two sides may be formed by the same.

[0032] 第2毛束群18像上述那样,通过被配置为敞开植毛面12a的中央方向,在长度方向上围住第1毛束群16,由第2毛束群18扫出的牙垢等污垢,易于向第2毛束群18的宽度方向的中央部分集中。 [0032] 2 tufts group 18 as described above, by being configured to open tufting surface 12a of the central direction in the longitudinal direction of the enclosed first tufts group 16, the second bristle group 18 swept out of tartar, etc. dirt, easy to the central portion of the second group of tufts 18 in the width direction of focus. 因此,在被第2毛束群18扫出的途中,可抑制污垢从第2毛束群18的宽度方向的两侧逃出,残留在牙间等的空隙中的情况。 Thus, on the way to the second group of tufts 18 swept out to suppress the dirt from both sides of the second group of tufts 18 in the width direction of the escape, the residual space between the teeth and the like in the case.

[0033] 此外,本例中,第2毛束群18的各个第2毛束18a,也包括第1毛束群16的第1毛束16a,被设置为千鸟状配置,但不限于这样的排列。 [0033] In addition, in this case, the second tufts each second tufts 18a group 18 also includes a first bristle group 16 first tufts 16a, is set to Chidori-shaped configuration, but not limited to such arrangement.

[0034] 第2毛束群18的排列形状不限于V字状,例如也可以是圆弧状。 [0034] The second group of tufts 18 arranged in the shape of a V shape is not limited to, for example, it may be arcuate. 第2毛束群18的排列形状,由于从牙间和牙颈部等的空隙将牙垢扫出的效果较好,优选V字状。 The second group of tufts 18 arranged in the shape, since the gap between the teeth and the tooth neck like tartar will sweep out the better, preferably V-shaped.

[0035] 本例中,1个第2毛束群18中,每组5个、共计10个第2毛束18a在长度方向上被设置成两组(两列)。 [0035] In this example, a second group of tufts 18, each set of five, a total of 10 second tufts 18a is set to two (two) in the longitudinal direction. 形成第2毛束群18的第2毛束18a的数量并不限于10根,可以是9根以下,也可以是11根以上。 Forming a second group of bristle tufts 18a of the second amount 18 is not limited to 10, it may be 9 or less, may be 11 or more. 形成第2毛束群18的第2毛束18a的数量,可以考虑第2毛束18a的直径等适当设定,优选3~18根,更优选5~10根。 Forming a second group of bristle tufts 18a of the second number of 18 can be considered the second tufts 18a is appropriately set the diameter, preferably 3 to 18, more preferably 5 to 10. 此外,第2毛束群18可由第2毛束18a在长度方向上配置为一组(一列)而形成,也可配置成三组以上(三列以上)而形成。 Additionally, the second group of tufts 18 by the second tufts 18a in the longitudinal direction is configured as a group (a) is formed, may also be configured as three or more (three or more) is formed. 第2毛束18a被配置为多列时,前端侧或后端侧的毛束18a的刷毛长度可形成为比中央区域侧的列的毛束18a的刷毛长度更长。 When the second tufts 18a is configured as a plurality of rows, tufts of bristles 18a of the front end side or rear end side of the length of the tufts may be formed as a central region than the side 18a of the longer length of the bristles of the column.

[0036] -对第2毛束群18的方式,在不损害本发明的效果的范围内,可以是不对称的。 [0036] - on the way to the second group of tufts 18, does not impair the effect of the present invention range can be asymmetric. 即, 前端侧的第2毛束群18和后端侧的第2毛束群18,在不损害本发明的效果的范围内,可以为不同形式。 That is, the second group of tufts 18 and the front end side of the rear end side of the second group of tufts 18, in a not impair the effects of the present invention ranges, for different forms. 此处的"对称"的意思是,以穿过植毛面12a的中心且在宽度方向上引的线为轴左右对称(轴对称)。 "Symmetry" means here is to pass through the center of tufting surface 12a and in the width direction of the symmetrical axis lead line (axis of symmetry). 例如,前端侧的第2毛束群18和后端侧的第2毛束群18中,第2毛束18a的数量可以不同, 第2毛束18a的排列形状也可以不同。 For example, the second group of tufts 18 and the front end side of the second group of tufts 18 in the rear end side, the second tufts may be different from the number 18a, 18a of the second arrangement of tuft shape may be different. 一对第2毛束群18中,优选第2毛束18a的数量、排列形状相同且对称。 A pair of second bristle group 18, the second number of tufts 18a preferably arranged in the same shape and symmetry.

[0038] 形成第2毛束18a的刷毛的横截面形状可举例如第1毛束16a中举出的,优选圆形。 [0038] the formation of the cross-sectional shape of the second tufts of bristles 18a may be, for example as in the first tuft 16a include, preferably circular. 第2毛束18a中,考虑使用感、刷扫感、清洁效果或者耐久性等,可将粗细不同的多根刷毛任意组合使用。 2 tuft 18a, in consideration of the use of flu, flu sweeping brush, and other cleaning effect or durability may be of different thickness plurality of bristles in any combination.

[0039] 第2毛束18a优选比第1毛束16a更容易挠曲。 [0039] Preferably the second tufts 18a more easily bent than the first tufts 16a. 据此,第2毛束18a的毛端容易进入牙间和牙颈部的空隙,牙垢除去的效果提高。 Accordingly, the second tufts 18a of Mao Duanrong easily enter the space between the tooth and the tooth neck, increase the effect of removing tartar. 可适当设定形成第2毛束18a的刷毛的数量,从而使第2毛束18a的直径为期望值。 May be appropriate to set the amount of the second tufts of bristles 18a is formed so that the second tufts 18a diameter expectations. 例如, 优选10~15根,更优选11~14根。 For example, preferably 10 to 15, more preferably from 11 to 14.

[0040] 第2毛束群18中的毛束18a间的最短距离,即从毛束18a的中心轴到相邻的毛束18a 的中心轴的距离,在最短处优选1.4~2.8mm,更优选1.8~2.2mm。 From the center axis of the [0040] second group of bristle tufts 18 in the shortest distance between 18a, i.e., from the central axis 18a of the bristle tufts 18a adjacent to, and in the shortest possible treatment is preferably 1.4 ~ 2.8mm, more preferably 1.8 ~ 2.2mm. 第2毛束18a和第1毛束16a的距离,即,从第2毛束18a的中心轴到相邻的第1毛束16a的中心轴的距离,优选1.5~4.0mm,更优选2.5~3.2mm。 Second tufts 18a and 16a of the first tufts distance, i.e., the distance from the central axis of the second tufts 18a adjacent to the first center axis 16a of the tufts, preferably 1.5 ~ 4.0mm, more preferably from 2.5 to 3.2mm.

[0041] [第3毛束群] 第3毛束群20在头部12的植毛面12a中,将第1毛束群16及夹住其的一对第2毛束群18从前端侧和后端侧夹住,在头部12的前端13侧和后端侧设有一对。 [0041] [3 tufts group] 3 bristle group 20 in the head anchoring surface 12a 12's, the first group of tufts 16 and clamped thereto a pair of second tufts group and 18 from the front side the rear end side of the grip, in front of the head 13 side and the rear side 12 is provided with a pair. 一对第3毛束群20相互分离。 One pair of the third group of tufts 20 separated from each other. 也就是说,形成一对第3毛束群20的第3毛束20a不被配置为围住第1毛束群16的宽度方向的两侧及第2毛束群18的宽度方向的两侧的样子。 That is, both sides are formed a pair of third tufts 320 of the first group of tufts 20a is not configured to surround the widthwise direction of the group of tufts 16 and second tufts on both sides in the width direction 18 of the group look. 如此一来,通过不配置为围住第1毛束群16的宽度方向的两侧及第2毛束群18的宽度方向的两侧的样子,与第2毛束群18相同地,各个第3毛束20a的毛端容易进入牙间和牙颈部等的空隙,其结果是,牙垢除去效率提高。 Thus, by the way is not configured to enclose both sides of the first group of tufts 16 in the width direction on both sides of the second group of tufts 18 in the width direction, and the second group of tufts 18 in the same manner, each of the first 3 tufts 20a of Mao Duanrong easily enter the space between the tooth and the tooth neck, etc., as a result, tartar removal efficiency is improved. 形成第3毛束群20的第3毛束20a,也可被植入头部12的植毛面12a的中央区域。 Forming the third group of the third tufts tufts 20a 20 also can be implanted in the head tufting surface 12a of the central region 12.

[0042] 第3毛束群20是通过植入多根第3毛束20a而形成的,那些多根第3毛束20a的刷毛长度,被对齐于比第2毛束群18更高的刷毛长度。 [0042] 3 bristle group 20 is formed by implanting a plurality of third tufts 20a formed by those third plurality of tufts of bristles 20a length, it is aligned in higher than the second group of tufts of bristles 18 length. 据此,第2毛束群18和第3毛束群20的边界部分形成了高度差。 Accordingly, the second group of tufts 18 and the third group of tufts boundary portion 20 forms a height difference. 通过第2毛束群18和第3毛束群20形成高度差,可高效扫出牙间和牙颈部等的空隙中存在的牙垢,因而牙垢除去效果提高。 By the second group of tufts 18 and the third gap 20 is formed tufts group difference in height can be efficiently swept out interdental tooth neck and the like in the presence of plaque, tartar removal effect and thus improved.

[0043]第3毛束群20是以敞开植毛面12a的中央方向,在第2毛束群18的外侧(前端侧及后端侧),将第1毛束群16在长度方向上围住的样子,排列各个第3毛束20a而形成的。 [0043] the third group of tufts 20 are Central direction open tufting surface 12a, in the second group of tufts 18 of the outer (front side and the rear side), the first group of tufts 16 surrounded in the longitudinal direction look, I arrange the third tufts 20a formed. 也就是说,第3毛束群20被形成为将第1毛束群16及第2毛束群18在长度方向上围住的样子。 That is, the third group of tufts 20 are formed as the first group of tufts 16 and second tufts 18 in the longitudinal direction of the group surrounded like. 此处, "敞开中央方向"的意思是,第3毛束群20并非被设置为相对宽度方向平行(沿宽度方向直线设置),且第3毛束群20中,配置于宽度方向两端的毛束20a被配置于,比配置于中央的毛束20a更接近中央区域侧的位置。 Here, "open center direction" means that the third group of tufts 20 are not disposed parallel to the opposite widthwise (width direction along a straight line set), and the third group of tufts 20 are disposed at both ends of the width direction of the hair 20a is arranged in the beam than in its central portion 20a at a position closer tufts central region side. 具体意思是,从侧面观察头部12时,存在第2毛束群18和第3 毛束群20在长度方向上不重叠的区域,和第2毛束群18和第3毛束群20在长度方向上重叠的区域。 Specifically means, as viewed from the side of the head 12, there is a second group of tufts 18 and the third group of tufts 20 in the longitudinal direction of the non-overlapping area, and the second group of tufts 18 and the third group of tufts 20 area overlapping the longitudinal direction. 第2毛束群18和第3毛束群20在长度方向上重叠的区域的宽度,在每1个所述区域上优选0·0~3·5mm〇具体地,本例中,第3毛束群20是以敞开植毛面12a的中央方向,在第2毛束群18的外侧(前端侧及后端侧)将第1毛束群16在长度方向上围住的样子,被设置为V字状。 The second group of tufts 18 and the third group of tufts 20 in the longitudinal direction of the width of the overlapping area, on each one of the regions preferably from 0 · 0-3 · 5mm〇 Specifically, in this case, the third batt group 20 is a central beam direction open tufting surface 12a, in the second group of outer tufts 18 (the front end side and the rear side) of the first group of tufts 16 in the longitudinal direction surrounded by the way, is set to V shape. 此外,本例中,V字状的第3毛束群20的角度,和第2毛束群18的角度相同。 Further, in this embodiment, the same third group of tufts 20 of the angle, and the second group of tufts V-shaped angle of 18. 此外,V字状的第3毛束群20的角度,也可以和第2毛束群18的角度不同。 Additionally, tuft cluster angle V-shaped section 320 to be first and second group of tufts 18 different angles.

[0044]像这样,通过将第3毛束群20配置成敞开植毛面12a的中央方向,将第1毛束群16在长度方向围住的样子,与第2毛束群18相同,污垢难以从第3毛束群20的宽度方向的两侧逃离,因而牙垢除去效果提高。 [0044] As described above, by the third tufts group 20 is configured to open tufting surface 12a of the central direction of the first tufts group 16 in the longitudinal direction surrounded by the way, and the second bristle group 18 are the same, the dirt is hard from both sides of the third group of tufts 20 in the width direction of escape, and thus increase the effect of removing tartar.
