Description

一种新型无带口罩 技术领域
本发明涉及口罩领域，具体为一种新型无带口罩。
背景技术
2013年PM2.5空气危害概念的出现，引发公众对空气污染问题的重视，使得口罩等防护用品在雾霾天气期间甚为畅销。口罩一般佩戴在口鼻部用于过滤进入口鼻的空气，以达到阻挡有害的气体、气味、飞沫，口罩可分为空气过滤式口罩和供气式口罩。用于防治PM2.5的口罩为空气过滤式口罩。
现有技术中的口罩，佩戴方式分为耳带式、头戴式、无带式，耳带式和头戴式均采用系带绳套在耳朵或头上，取戴均十分不便。现有的无带式口罩，如中国专利申请号为CN200820062155.8，公开了一种无绳口罩，由口罩罩体和粘耳组成，在传统口罩罩体四角，各设置一个内层涂有医用可反复使用、清洗的胶粘剂的粘耳。虽然解决了佩戴不方便的问题，但是粘耳使用多次后不具有粘性，同时口罩在取下时，粘耳与脸部撕扯，造成脸部疼痛。无论过滤材料在阻止有害颗粒物多么有效，口罩边缘上的任何泄露都可以导致过滤材料的优点失去意义。如中国专利申请号CN201320653195.0，公开了一种无系带口罩，包括用于覆盖口鼻的口罩主体，所述口罩主体内侧外沿具有压敏胶贴层，所述压敏胶贴层将口罩主体保持在面部，并封闭面部皮肤与口罩主体之间的缝隙，采用热敏胶黏贴，同样有口罩取下时产生疼痛感，同时热敏胶粘附在脸上时，产生不适，夏天出汗时容易脱落。这 些口罩的不足，常常给佩戴者带来健康的威胁，所以，开发一款没有边缘泄漏、可牢固施用于面部的新型口罩，满足广大使用者的健康需求，意义非常重大。
发明内容
为解决上述问题，本发明公开了一种新型无带口罩，该口罩不使用带子，穿戴方便；密封性好，边缘无泄漏；呼吸顺畅，舒适度高；可牢固适用于面部，粘附性好。
为了达到以上目的，本发明提供如下技术方案：
一种新型无带口罩，所述口罩包括由内至外依次缝合设置的保护层、透气层、过滤层、防护层，所述保护层内侧设有支撑凸起、粘性压紧条、弹性牵引带，所述支撑凸起呈凸起状，所述支撑凸起设置在保护层与人体鼻翼接触的位置或/和保护层与人体下颌接触的位置，所述支撑凸起为硅胶支撑凸起；所述粘性压紧条设置在保护层的边缘，所述弹性牵引带的两端缝合在保护层上，所述弹性牵引带设置在保护层与人体鼻梁接触的位置；所述透气层为网格状，所述过滤层为高效活性炭布层，所述口罩的下端设置成能兜住下巴的弧形，所述口罩的下端缝合弹性绳。
作为优选，所述口罩设置鼻梁铝条，所述鼻梁铝条连接在所述防护层外侧，所述鼻梁铝条的中部向前弯折呈弧形与人体的鼻梁相吻合，所述鼻梁铝条与弹性牵引带的位置错开设置。
作为优选，所述防护层表面设有防雾涂层。在防护层外侧表面喷涂防雾涂层，可防止冬天的雾气进入口罩，起到除雾效果。
进一步的，所述粘性压紧条为硅胶压紧条、凝胶压紧条、树脂压紧条的其中一种。采用硅胶压紧条、凝胶压紧条或树脂压紧条，使得口罩与脸型更吻合，同时硅胶、凝胶材质温和，不会挤压到脸部。
进一步的，所述粘性压紧条表面覆有同样大小的解离纸层。在不适用后，将解离纸层覆盖在粘性压紧条上，保持粘性压紧条的清洁卫生，可实现重复口罩的使用。
进一步的，所述口罩的上部设置成能兜住鼻子的V型。上部设置呈V型，能更好的兜住鼻子。
进一步的，所述保护层采用棉布层，所述透气层采用硬质纱布层，所述防护层采用无纺布层。防护层采用无纺布层，具有防潮、透气、柔软、价格低廉的特点；透气层采用硬质纱布，通透性好，起到支撑效果；保护层直接接触人体面部，采用棉布层，柔软，舒适。
本发明的工作过程及原理：空气经防护层、过滤层、透气层、保护层过滤后进入到人体的口鼻，防护层为第一层过滤层，可过滤大颗粒粉尘，过滤层由高效活性炭布构成过滤层，可进一步的过滤MP2.5粉尘、有机物气体及其他有害气体，保证口罩的过滤效果；透气层设置在过滤层和与人体脸部直接接触的保护层之间，一方面起到支撑的作用，将过滤层与保护层有效的分离，形成空气流动空间，使得人体呼吸顺畅，空气流通性好，另一方面，避免过滤层与保护层的直接接触，直接避免了活性炭吸附的有害物质与保护层的直接接触；保护层直接与人体脸部接触，在保护层内侧设有支撑凸起、粘性压紧条、弹性牵引带，支撑凸起设置在保护层与人体鼻梁接触的位置或/和保护 层与人体下颌接触的位置，使得人体的口鼻与口罩之间留有一定的间隙，一方面可增强空气的流通性，使得呼吸顺畅，口罩的保护层直接接触到脸部，会生热，使人体燥热，尤其是夏天，不仅呼吸不畅，还十分闷热，另一方面凸起使用硅胶，硅胶的材质柔软，具有一定的粘附性，增强人体与口罩之间的粘附效果，口罩不易脱落；同时粘性压紧条设置在保护层的边缘，粘性压紧条可使得口罩与人体脸部的更紧密的接触，口罩的密合性更好，能够将口罩直接罩在脸上而不会脱落，弹性牵引带具有弹性起到牵引的作用，避免口罩滑落；三重防滑设置，无需使用带子挂在耳朵或头上，佩戴简单方便，同时相比于现有技术中采用松紧绳的做法来说，不会挤勒脸部，佩戴舒适；口罩的下端设置成能兜住下巴的弧形并缝合弹性绳，一方面可增强密封性，另一方面可使得口罩更加牢固的施用于面部。不采用现有技术中使用的压敏胶、粘耳等，增强佩戴者的舒适度。
本发明具有如下优点：
(1)本发明的无带口罩，不使用带子，可牢固施用于面部，佩戴方便，舒适度高，不勒不紧；
(2)本发明新型无带口罩，过滤性能好，能有效过滤PM2.5粉尘、有机物气体及其他有害杂质；
(3)本发明的无带口罩，密封性能好，边缘没有泄漏；
(4)本发明的新型无带口罩，透气性能好，佩戴后呼吸顺畅。
