Description

一种立体杯罩 技术领域
本实用新型涉及一种口罩，特别是涉及一种立体结构的杯罩。
背景技术
在日常生活和医疗领域中，口罩的应用越来越广泛。现有的口罩主要为平面结构。授权公告号为CN201384073Y的中国实用新型专利于2010年1月20日公开了一种“医用口罩”,其技术方案是：一种医用口罩，涉及卫生防护用品，由绑带、纺织材料缝合而成，设有多层纺织材料，纺织材料之间设有骨架。既保留了传统口罩的防尘、防寒、防飞沫功 能，又增加了防毒、防臭、防病菌和可根据季节使用不同一侧进行调节温度的功能。可广泛应用于医院医务人员为防止各种病毒和环卫工人防止各种垃圾气味和厕所臭气时佩带。
技术问题
但是由于这种医用口罩为非立体结构，佩戴时口罩会压在鼻子和嘴唇上，从而导致佩戴舒适性差、呼吸不畅、气密性不好，还会影响正常的交谈。
技术解决方案
本实用新型所要解决技术问题是，提供一种佩戴舒适、过滤效果好、不会影响正常交谈的杯罩。
为解决以上技术问题，本实用新型的技术方案是：一种立体杯罩，包括相互叠合的无纺布层和过滤层，所述立体杯罩中设有凹形支撑架。
优选的，所述过滤层为过滤棉层。
作为本实用新型的改进，所述无纺布层包括前无纺布层、中间无纺布层和后无纺布层，所述立体杯罩包括依次叠合的前无纺布层、支撑架、中间无纺布层、过滤棉层和后无纺布层。
作为本实用新型进一步的改进，所述支撑架包括不在同一个平面内且相互连接的第一环和第二环。
作为本实用新型更进一步的改进一，所述支撑架还包括与所述第二环直接或者间接连接的若干次级环，所述若干次级环所围成的面积依次减小，所述若干次级环之间以及所述第二环与第一级次级环之间均为镂空结构连接。
作为本实用新型更进一步的改进二，所述第一环和所述第二环之间为镂空结构。
优选的，所述第二环所围成的面积小于所述第一环所围成的面积。
作为本实用新型更进一步的改进三，所述第二环同镂空架连接，所述镂空架为十字架结构。
 有益效果
通过实施本实用新型可取得以下有益效果：
一种立体杯罩，包括相互叠合的无纺布层和过滤层，所述立体杯罩中设有凹形支撑架，凹形支撑架可以保证立体杯罩的内侧和口鼻之间有一定的间隙，从而不会影响到日常的言语交谈。所述过滤层为过滤棉层，所述无纺布层包括前无纺布层、中间无纺布层和后无纺布层，所述立体杯罩包括依次叠合的前无纺布层、支撑架、中间无纺布层、过滤棉层和后无纺布层，依次相互叠合在一起的多个过滤层使得口罩的过滤效果更好。
所述支撑架包括不在同一个平面内且相互连接的第一环和第二环，所述第二环同镂空架连接，所述镂空架为十字架结构，所述第一环和所述第二环之间为镂空结构，所述第二环所围成的面积小于所述第一环所围成的面积。这种结构在保证立体杯罩的内侧和口鼻之间有足够间隙的前提下大大降低了杯罩的重量，使得口罩更为轻巧，佩戴更为舒适。
所述支撑架还包括与所述第二环直接或者间接连接的若干次级环，所述若干次级环所围成的面积依次减小，所述若干次级环之间以及所述第二环与第一级次级环之间均为镂空结构连接，所述第一环和所述第二环之间为镂空结构。这种近似于半球状的镂空结构最大限度地增加了过滤面积，保证了吸气的顺畅，避免了闷气。
