Abstract

本发明公开了一种立体口罩，包括口罩本体和位于口罩本体两侧的橡筋耳带，口罩本体具有由左半部分和右半部分压制而成的立体结构，口罩本体内层和外层均为无纺布层，口罩本体由外至内分别包括外无纺布层、高效过滤层、抗菌层和内无纺布层，外无纺布层、高效过滤层、抗菌层和内无纺布层压制成一体结构。本发明内层设置抗菌层，对人体无刺激、无致敏作用，设置在高效过滤层中的折线型的褶皱可以降低气流流速，从而提高过滤效率。设计为立体状的口罩，使得使用者的鼻子部位不直接与口罩接触，避免闷热。本发明可以阻隔细菌、流感病毒和PM2.5的危害。

Description

一种立体口罩
技术领域
本发明涉及一种立体口罩。
背景技术
口罩一般指戴在口鼻部位用于过滤进出口鼻的空气，以达到阻挡有害的气体、气味、飞沫进出佩戴者口鼻的用具，多以布或纸等制成。现有的口罩结构较简单，不透气，过滤效果低，容易使人有不舒适感，并且无法阻止流感病菌和PM2.5的危害。
发明内容
本发明为了克服上述技术问题的不足，提供了一种立体口罩，可以完全解决上述技术问题。
解决上述技术问题的技术方案如下：
一种立体口罩，包括口罩本体和位于口罩本体两侧的橡筋弹性耳带，所述的口罩本体具有由左半部分和右半部分压制而成的立体结构，所述的口罩本体内层和外层均为无纺布层，所述的口罩本体由外至内分别包括外无纺布层、高效过滤层、抗菌层和内无纺布层，所述的外无纺布层、高效过滤层、抗菌层和内无纺布层压制成一体结构。
所述的高效过滤层上设置有折线型的褶皱。
所述的橡筋弹性耳带具有与口罩本体的连接部和环状部。
本发明结构简单，设置在高效过滤层中的折线型的褶皱，加大了高效过滤层的比表面积，降低了气流流速，从而提高了过滤效率，过滤效率达到96.9％，降低了呼吸阻力，气流阻力为9.1mmH2O。设计为立体状的口罩，使得使用者的鼻子部位不直接与口罩接触，避免闷热。本发明可以阻隔细菌、流感病毒和PM2.5的危害。
附图说明
下面结合附图和具体实施方式对本发明作进一步详细的说明。
图1为本发明的结构示意图；
图2为本发明的四层结构示意图；
图3为高效过滤层的褶皱示意图；
图中：1为口罩本体，2为弹性耳带，3为外无纺布层，4为高效过滤层，5为抗菌层，6为内无纺布层，7为褶皱。
具体实施方式
如图1所示的一种立体口罩，包括口罩本体1和位于口罩本体1两侧的橡筋弹性耳带2，所述的口罩本体1具有由左半部分和右半部分压制而成的立体结构，所述的口罩本体1内层和外层均为无纺布层，所述的口罩本体1由外至内分别包括外无纺布层3、高效过滤层4、抗菌层5和内无纺布层6，所述的外无纺布层3、高效过滤层4、抗菌层5和内无纺布层6压制成一体结构。所述的高效过滤层4上设置有折线型的褶皱7。所述的褶皱7布满整个高效过滤层4。所述的高效过滤层4为活性炭纤维材料层。所述的橡筋弹性耳带2具有与口罩本体的连接部和环状部。
本发明结构简单，设置在高效过滤层中的折线型的褶皱，加大了高效过滤层的比表面积，降低了气流流速，从而提高了过滤效率，降低了呼吸阻力。设计为立体状的口罩，使得使用者的鼻子部位不直接与口罩接触，避免闷热。本发明可以阻隔细菌、流感病毒和PM2.5的危害。
