Description

一种卫生巾
技术领域
本发明属于卫生制品技术领域，尤其是涉及一种卫生巾。
背景技术
女人每月都会有月经，这是女人正常的生理现象，但是，为了防止无意中流出来的经血给衣物等带来的不便，人们设计出了多种样式和规格的卫生巾，来解决每月经血带来的不便和尴尬。但是，公知的卫生巾具有吸附性高，防水性能好的特性，在防水的同时，阴部的潮气等也不易排出来，结果，就容易造成阴部和屁股上长有痈疮等，严重影响了卫生巾的舒适性能。如何让女人在使用卫生巾时，既可以满足不渗漏，造成不必要的污染和尴尬，又可以具有较大的通气性能，为女人的阴部营造一个舒适的空间成为急需解决的一大难题。
发明内容
有鉴于此，本发明旨在提出一种卫生巾，以克服现有技术的不足，提供透气性能好，透气体验性能佳的卫生巾。
为达到上述目的，本发明的技术方案是这样实现的：
一种卫生巾，包括面层、吸收性本体和底膜，所述吸收性本体位于所述面层和所述底膜之间，所述面层和所述吸收性本体之间设有导流层，所述吸收性本体包括芯体以及包覆芯体的包覆层，所述芯体上开设有通气孔。
进一步的，所述芯体与底膜之间还包括泡腾剂芯片，所述泡腾剂芯片包括上隔离层、泡腾剂颗粒、下隔离层，各层间经热合或胶合结合在一起。
进一步的，所述上隔离层、下隔离层选自湿强纸、无尘纸、多亲无纺布中的一种或几种。
进一步的，所述泡腾剂芯片位于芯体和底膜之间。
进一步的，所述泡腾剂芯片位于芯体和包覆层之间。
进一步的，所述泡腾剂芯片位于包覆层和底膜之间；
进一步的，所述泡腾剂芯片长度小于或等于芯体长度；
进一步的，所述泡腾剂芯片宽度小于或等于芯体宽度；
进一步的，所述通气孔沿卫生巾长度和宽度方向均不连续。
进一步的，所述通气孔在所述芯体的宽度方向上等间隔分布。
进一步的，所述通气孔在所述芯体的宽度方向上非等间隔分布，所述通气孔在所述芯体宽度方向上由两侧向中心分布密度逐渐增大。
进一步的，所述通气孔的深度小于或等于所述芯体的厚度。
进一步的，所述导流层位于卫生巾宽度方向的中央，在卫生巾长度方向上延伸。
进一步的，所述包覆层在面向底膜的面上有一个部分重叠的部位。
进一步的，所述面层为无纺布，所述无纺布为打孔无纺布或添加有无味的凉味剂的无纺布。
进一步的，所述底膜为透气底膜。
相对于现有技术，本发明所述的卫生巾具有以下优势：
本发明所述的卫生巾，在芯体内设置通气孔和采用透气底膜，增强了透气性能；采用无味的凉味剂的无纺布或打孔无纺布，具有极好的透气展示性能；芯体与底膜间还包括泡腾剂芯片，使用期间，液体触发泡腾剂后，会有气体产生，加强气体流动，使用过程更舒适。
