Description

一种防静电保健梳子 技术领域
本发明涉及梳理头发用的梳子，具体涉及一种防静电保健梳子。
背景技术
人们在梳头时，由于梳子的梳齿会与头发产生大量的摩擦，产生的静电会使得头发打卷，梳理困难；而且静电会伤害头皮，损伤发质，断发更容易产生。现有技术中的防静电梳子设计主要有两种思路，一种是抑制起电，如选用本身含有适量水分且摩擦不易起电的材料来制作梳子，如木梳，牛角梳；另一种是导引电荷，使电荷不易大量聚集而形成静电，如加湿抗静电、负离子抗静电或其他导电材料抗静电。
对于第一种设计而言，梳发体验和材料的价格成为制约此种产品广泛推广的因素，例如牛角梳之类的抗电梳大多只有单排梳齿，梳发体验不够好，原材料的获取和加工都较难，导致价格也较昂贵，普通消费者难以消费；
而对于第二种设计来说，加湿抗静电基本是在梳子头部的空腔内加入液体(如水)，从而减少静电的产生。然而，加湿梳发易有不适感，特别是天气寒冷时，使用局限性较大。而导电材料抗静电则是使用导电材料制作梳齿，将产生的电荷通过梳齿导引而使之电荷无法顺利聚集形成静电。但梳子整体采用导体材料制成，且需导电线路将电荷导去导电区域，不仅使梳子制作成本昂贵，也使得内部结构复杂，并且梳子的主要造型也多为单排梳齿的扁梳，不具备按摩保健的功能，纯导体材料也有安全隐患。此外，还有在塑胶原料加盐类离子的注塑梳子，在吸收空气中的水分后，附于梳子的表面，梳头时可以迁移电荷，但当室内湿度环境发生变化，即空气干燥、含水量低时，这些梳子迁移电荷的能力就会大大降低。还有采用负离子发生器的梳子，该种设计防静电功能性很好，但成本高昂，且当正负离子碰撞时，发出的嗤嗤声音容易对使用者造成惊吓，用户体验不好。
针对梳发时会产生静电，而现有设计存在的或是材料昂贵，或是导电效果不佳，或是导电设计复杂等局限性而无法大力推广使用的问题，本发明设计了一种防静电保健梳子，利用在梳子主体上涂覆多层膜，在梳子表面形成导电更快的复合半导结构的产品，提高电子的迁移率，使产生的电荷得到更快地疏导，从而防止静电的产生，导电效果好且成本较低，也更安全可靠。
发明内容
本发明针对现有技术中的不足，提供了一种防静电保健梳子，本梳子整体上涂覆一层 导电金属膜，以及在导电金属膜上涂覆一层树脂保护膜，树脂保护膜层的树脂骨架实体挡住了部分在导电金属膜层游离的电子，二者复合使金属膜的导电性能部分下降，由原本的纯导体转变成了复合半导结构的产品，而具备半导体材料迁移电荷速度更快的性能，整体涂膜形成整体导通，并通过人手的握持，将电荷更快地疏导引走，使之无法顺利在梳齿的尖端聚集形成静电，伤害头皮及头发。
一种防静电保健梳子，梳子主体包括梳齿部及握持部，所述握持部、梳齿部的外表面均涂覆有第一中间导电层，所述第一中间导电层上又涂覆有第一降导保护层。所述梳子可以是多排梳齿的梳子或传统单排梳齿的扁梳，只需具有握持部可用于握持梳子即可，即所述梳子可以是带手柄的或不带手柄的。所述第一中间导电层和第一降导保护层形成导电更快的产品，称为复合半导结构。该复合半导结构使梳子表面的阻值处于半导体材料的阻值范围，具备半导体材料可更快迁移电荷的性能。
优选地，所述握持部和梳齿部是一体成型的空心结构，其内表面均涂覆有第二中间导电层，所述第二中间导电层上又涂覆有第二降导保护层。梳子的握持部和梳齿部内部中空且具有与外表面相同的涂膜复合半导结构，可提高整体导通的稳定性，更好地实现更快迁移电荷的技术目的。
优选地，所述梳齿部的头部的正面设有开口，开口设置有向上拱起的气囊皮，所述气囊皮上开有气囊通孔及固定置入有多个以梳齿部的中心环形地分布的梳齿。气囊通孔的设置使得气囊皮与空心结构的梳子形成的半封闭空腔有空气的进出，使得气囊皮更好地根据头部的不同位置收缩伸展，起到按摩头皮，舒缓紧张的效果。
优选地，所述气囊皮为橡胶皮，向上拱起外凸的橡胶皮与梳齿部头部的开口的内壁紧密贴合；所述橡胶皮接近握持部的一端开设有气囊通孔；所述橡胶皮的内外表面均涂覆有第一中间导电层或第二中间导电层，其上又涂覆有第一降导保护层或第二降导保护层。第一中间导电层与第二中间导电层优选是相同材质的涂层，第一降导保护层与第二降导保护层优选是相同材质的涂层。橡胶皮价格低廉，方便易得，且在橡胶皮上涂覆软膜的工艺也比较成熟，可以与梳子主体形成整体导通，使在梳齿上产生的电荷顺着梳齿、气囊皮、梳齿部和握持部流淌，经人手导走。
优选地，所述第一中间导电层和第一降导保护层的复合半导结构的表面阻值为103Ω至1011Ω，所述第二中间导电层和第二降导保护层的复合半导结构的表面阻值为103Ω至1011Ω。表面电阻测试仪测得此表面阻值控制在了半导体状态的阻值范围内。由于小孩在玩梳子时可能会误将梳子齿插进插座的插孔中，这样设计的目的是降低了纯导体材料制成的梳子发生触电伤害的风险，更安全可靠。
优选地，所述第一中间导电层和第一降导保护层的复合半导结构的表面阻值为104Ω至 109Ω，所述第二中间导电层和第二降导保护层的复合半导结构的表面阻值为104Ω至109Ω。表面电阻测试仪测得此表面阻值控制在了半导体状态的阻值范围内。由于小孩在玩梳子时可能会误将梳子齿插进插座的插孔中，这样设计的目的是降低了纯导体材料制成的梳子发生触电伤害的风险，更安全可靠。且复合半导结构的表面阻值处于此范围时，快速导电的性能得到较大的提升；而这表面阻值决定于复合半导结构的膜层材料，膜层厚度，梳子表面曲率等因素。
优选地，所述握持部及梳齿部的正面和背面均分布有多个半球形体的凸起。凸起的设置不仅可以在按压时带来按摩保健的功效，更重要的是，在增加了降导保护层的厚度后，使透过树脂间隙的自由电荷减少，而凸起的形状可改变表面电荷密度，使导电层表面的自由电荷更多地发生转移，从而降低梳子表面的阻值，使之更接近于半导体的阻值范围，增强抗静电效果。
优选地，所述第一中间导电层和第二中间导电层材质相同，均是一层涂覆在所述梳子主体表层的导电金属膜或导电合金膜，其膜厚不低于2μm。导电金属膜或导电合金膜的膜厚小于2μm时，所形成的的复合产品导电性能较差，表现在速度慢或稳定性不佳，一定程度上，随着膜厚的增大，导电效果也会越好。
优选地，所述第一降导保护层和第二降导保护层材质相同，均是一层透明的树脂保护膜，其膜厚不低于3μm。树脂保护膜的设置一方面是为了与导电金属膜或导电合金膜复合形成复合半导结构的产品，降低部分导电性能，但导电速率更快；另一方面也是为了防止导电金属膜或导电合金膜的氧化，保障了导电效果和耐用性，也延长了梳子的使用寿命。
优选地，所述导电金属膜或导电合金膜和所述树脂保护膜的涂覆方法是采用水电镀或真空电镀，且所述透明的树脂保护膜可使用不同的色剂着色。透明的树脂保护膜容易着色，可在后工序加工中添加不同的色剂，制造出任意色泽的梳子，消费者可选择的颜色更多，而不再局限于普通防静电梳的单一色彩，满足了市场的需求。
本发明的有益效果在于：
相对于现有技术而言，使用导电材料整体成型的梳子抗静电性能是最优的，然而成本高，制造难；本发明的防静电保健梳子通过在梳子的握持部、梳齿部的外表面均覆盖有一层导电金属膜和一层树脂保护膜，树脂保护膜层的树脂骨架实体挡住了部分在导电金属膜层游离的电子，二者复合使金属膜的导电性能部分下降，由原本的纯导体转变成了复合半导结构的产品，而具备半导体材料迁移电荷速度更快的性能，整体涂膜形成整体导通，并通过人手的握持，将电荷更快地疏导引走，使之无法顺利在梳齿的尖端聚集形成静电，伤害头皮及头发，起到防止静电形成的效果，保护头发，使梳理头发时更顺畅，不发生打卷 现象；其次，本发明还具备一定的按摩保健功能，由于梳理头发会有一定的按压动作，气囊皮上的气囊通孔会在梳发过程中往空腔内吸入和排出适量的空气，使气囊皮波动，从而多圈梳齿的梳理能根据头部的不同接触位置而变化，让头皮感到舒适而无压迫感，克服了单排梳齿给人感觉比较轧硬的问题，达到按摩保健的效果。

具体实施方式
下面结合附图和实施例对本发明作进一步说明。
如图所示，一种防静电保健梳子，梳子主体3包括梳齿部及手柄部；手柄部、梳齿部及梳齿的主体由塑料或其他非导电性材料制成。
梳子的握持部、梳齿部及梳齿的外表面均涂覆有第一中间导电层2，第一中间导电层2上又涂覆有第一降导保护层1。如附图所示，本发明的梳子可以是具有多排梳齿的梳子或传统单排梳齿的扁梳，只需具有握持部可用于握持梳子即可，即所述梳子可以是带手柄的或不带手柄的(不带手柄的扁梳的握持部10，不带手柄的扁梳的梳齿部11，带手柄的扁梳的握持部12，带手柄的扁梳的梳齿部13)。本发明的第一中间导电层2加第一降导保护层1形成导电更快的产品，称为复合半导结构。该复合半导结构使梳子表面阻值处于半导体材料的阻值范围，具备半导体材料可更快迁移电荷的性能。
梳子的握持部和梳齿部是一体成型的空心结构，其内表面均涂覆有第二中间导电层4，且第二中间导电层4上又涂覆有第二降导保护层5。梳子的握持部和梳齿部内部中空且具有与外表面相同的涂膜复合半导结构，可提高整体导通的稳定性，更好地实现更快迁移电荷 的技术目的。
梳子的握持部、梳齿部的内外表面均涂覆有一层第一中间导电层2或第二中间导电层4，第一中间导电层2和第二中间导电层4实际上都是一层导电金属膜，例如铜膜、铝膜或合金膜，也可以是银膜；根据产品的不同定位，普通梳子产品使用铜膜，高端梳子产品使用银膜等导电性能更好但成本更高的金属膜，即产品本身该金属膜层不仅局限于铜，而铝，镍，银，金或合金等均可根据产品的需要而选用不同的中间镀层；本发明的梳子可以是具有多排梳齿的梳子或传统单排梳齿的扁梳。
梳子的梳齿部的头部的正面设有椭圆形或圆形开口，开口中设置有向上略微拱起的气囊皮，气囊皮上开有气囊通孔8及固定置入有多个以梳齿部的中心环形地分布的梳齿。梳子的梳齿与气囊皮固定连接，但由于气囊皮是柔性材料制成，如橡胶皮等，梳齿可以在气囊皮上摆动；气囊通孔8的设置使得气囊皮与空心结构的梳子形成的半封闭空腔有空气的进出，使得气囊皮更好地根据头部的不同位置收缩伸展，加上可以摆动的梳齿，可起到按摩头皮，舒缓紧张的效果。
本发明使用的气囊皮优选为橡胶皮，向上拱起外凸的橡胶皮的外边缘与梳齿部头部的圆形开口或椭圆形开口的内壁紧密贴合，且在橡胶皮接近握持部的一端开设有气囊通孔8；橡胶皮的内外表面也涂覆有第一中间导电层2或第二中间导电层4，其上又覆盖有第一降导保护层1或第二降导保护层5。第一中间导电层2与第二中间导电层4优选是相同材质的涂层，第一降导保护层1与第二降导保护层5优选是相同材质的涂层。即材质相同时，两者是同样的东西，只是定义的说明名称不同而已。不同于现有的加导电剂改良的导电橡胶皮，本发明的橡胶皮可采用天然橡胶皮，无需增加改良工艺，直接在其上涂覆一层导电金属软膜和一层树脂保护软膜，其金属和树脂的选择与前面所讲的导电金属膜的金属和树脂保护膜的树脂是一致的，属于同一个涂覆产品。且橡胶皮价格低廉，方便易得，且在橡胶皮上涂覆软膜的工艺也比较成熟，可以与梳子主体形成整体导通，使在梳齿上产生的电荷顺着梳齿、气囊皮、梳齿部和握持部流淌，经人手导走。
第一中间导电层2加第一降导保护层1的复合半导结构的表面阻值为103Ω至1011Ω，第二中间导电层4加第二降导保护层5的复合半导结构的表面阻值为103Ω至1011Ω。根据欧姆定律，阻值越大，阻碍电流的能力越大。也就是说，阻值越小，迁移电荷的能力也就越强。导体、半导体与绝缘体通常以电阻率区分；所谓的电阻率，即常温下20℃的电阻与横截面积的乘积与长度的比值，与导体的长度、横截面积等因素无关，是导体材料本身的电学性质，由导体的材料决定，且与温度有关；通过本申请的复合半导结构，改变了原来梳子导电层表面的电阻率，也是改变了原来导电层表面的电阻。因为表面电阻简单易懂，且手持的表面电阻测试仪比台式的电阻率测试仪更方便携带和测算，所以在阐述时利用表 面电阻的变化，以说明梳子表面涂覆多层膜形成的复合半导结构可防静电的原理。需要明确的是，导电性能与电荷迁移性能是不同的。金属的导电性比半导体更好，是因为金属体的内部场强均匀，而半导体内部会感应出反向电荷，出现电位移，形成逆向场，所以宏观上来看，通过金属的电流比半导体的强，即导电性更好；而半导体由于存在空穴、电子，电荷的迁移率是比金属体还高的，即电荷在半导体中的定向运动速度更快，能更快地将电荷迁移疏导走。所以，利用这点本申请的梳子表面的复合半导结构可实现防止梳发时静电的产生。
第一中间导电层2加第一降导保护层1的复合半导结构的表面阻值更优选地为104Ω至109Ω，第二中间导电层4加第二降导保护层5的复合半导结构的表面阻值更优选地为104Ω至109Ω。表面电阻测试仪测得此表面阻值控制在了半导体状态的阻值范围内，因为梳子是家庭用品，随处可放，幼童随时有可能拿到并当成玩具。因此，梳子主体3表面设计成复合半导结构可降低部分导电性能，使通过梳子的电流减小，从而降低幼童拿梳子碰触电源插孔发生触电的危险性，使用会更安全可靠。且复合半导结构的表面阻值处于此范围时，快速导电的性能得到较大的提升；而这表面阻值决定于复合半导结构的膜层材料，膜层厚度，梳子表面曲率等因素。
握持部及梳齿部的正面和背面均分布有多个半球形体凸起9。凸起的设置不仅有提供按压时带来的按摩保健功效；更重要的是，根据高斯定律，在静电场中，穿过任一封闭曲面的电场强度通量只与封闭曲面内的电荷的代数和有关，且等于封闭曲面的电荷的代数和除以真空中的电容率。换言之，导体表面有电荷堆积时,电荷密度与导体表面的形状有关。在凹的部位电荷密度接近零,在平缓的部位小,在尖的部位最大。考虑到梳子主体3表面会接触到人手或头皮，故设置成凸起的半圆状球体，而不是一味地为了更快迁移电荷而设置成尖锐的凸起，且此形状由模具注塑是非常容易实现的。所以当在增厚降导保护层的厚度后，使透过树脂间隙的自由电荷减少，而凸起的形状可改变表面电荷密度，使导电层表面的自由电荷更多地发生转移，降低表面阻值(实际降低表面电阻率)，使之更接近于半导体的阻值范围，增强抗静电效果。
第一中间导电层2和第二中间导电层4材质相同，均是一层涂覆在梳子主体3表层的导电金属膜或导电合金膜，其膜厚不低于2μm。导电金属膜或导电合金膜的膜厚小于2μm时，所形成的的复合半导结构导电性能较差，表现在速度慢或稳定性不佳，一定程度上，随着膜厚的增大，导电效果也会越好。考虑成本时，可根据产品的定位适当选用合适的膜原料和膜厚度。
第一降导保护层1和第二降导保护层5材质相同，均是一层透明的树脂保护膜，用以降低部分导电性能，其膜厚不低于3μm。树脂保护膜的设置一方面是为了与导电金属膜或 导电合金膜复合形成复合半导结构的产品，降低部分导电性能但提升梳子表面迁移电荷能力，使导电更快；另一方面也是为了防止导电金属膜或导电合金膜的氧化，保障了导电效果和耐用性，也延长了梳子的使用寿命。由于树脂保护膜采用的是离子型的大孔弱酸丙烯酸酯清漆等，此类树脂本身在树脂骨架实体6间存在许多树脂孔隙7，第一或第二中间导电层上的自由电荷可经过树脂孔隙7游离到梳子表面，达到我们需要降低部分导电性能而又不失去导电性能的作用，且使之与导电金属膜或导电合金膜形成的复合半导结构的产品具备半导体迁移电荷更快的性能。
为保证复合半导结构的表面阻值处于半导体范围，具备半导体优秀的电荷迁移性能的要求，其导电金属膜或导电合金膜的膜厚不低于2μm，树脂保护膜的膜厚不低于3μm。在室温25度，相对湿度65度的环境下，测试出梳子的表面阻值需在103到10 11Ω之间，更优的在104到10 9Ω之间。同时可以适当增厚降导保护膜的厚度而增加产品的耐用性和寿命。
导电金属膜或导电合金膜和所述树脂保护膜的涂覆方法是采用水电镀或真空电镀，相比较现有的牛角梳或导电碳纤维梳在成型加工过程中工序繁多且着色难的问题，色彩单调，难以满足不同顾客的审美要求；本发明的梳子表面是一层透明的树脂保护膜，在后工序加工中可添加不同的色剂，树脂容易着色，可制造出任意色泽的梳子，满足市场需求。
根据上述说明书的揭示和教导，本发明所属领域的技术人员还可以对上述实施方式进行变更和修改。因此，本发明并不局限于上面揭示和描述的具体实施方式，对本发明的一些修改和变更也应当落入本发明的权利要求的保护范围内。此外，尽管本说明书中使用了一些特定的术语，但这些术语只是为了方便说明，并不对本发明构成任何限制。
