背景技术Background technique

因科技发达使工商业快速发展，使人类生活文明提升，进而带动工业以及汽车业的发达，诸如飞机、船舶以及汽车等交通工具则因人类商业活动频繁而已成为不可缺少的交通工具，此些交通工具虽带给人类便利，但使用所排放的废气已严重污染人类赖以为生的空气，并严重威胁人类的健康，且在空气中存在各种眼睛看不见有害的汽车废气微尘粒子以及毛发、纤维以及各种工业污染有害烟气味等物，因此，人类在各个场所空间内一直不断的吸入这些有害健康的空气异质，进而产生了各种疾病。近年来多种致命性的流行病毒都是以空气传播感染他人。The development of science and technology has led to the rapid development of industry and commerce, the improvement of human civilization, and the development of industry and the automobile industry. Vehicles such as airplanes, ships, and automobiles have become indispensable vehicles due to frequent human business activities. These vehicles Although it brings convenience to human beings, the exhaust gas emitted by the use has seriously polluted the air on which human beings live and seriously threatened human health, and there are various harmful car exhaust dust particles, hair, and fibers in the air that are invisible to the eyes. As well as various industrial pollution and harmful smoke smells, etc. Therefore, human beings have been inhaling these harmful air heterogeneities in various places and spaces, and various diseases have been produced. In recent years, a variety of deadly epidemic viruses are transmitted through the air to infect others.

长久以来，人类为避免吸入受污染的有害空气，除室内使用的各种空气过滤净化设备外，大多数外出和群众场所则以配戴口罩来避免吸入受污染的有害空气或以空气散布的流行病毒，而口罩的种类也相当多，依所需用途以及要求各有不同，其分为一般用、医护用、工业用、疫区用来及火场使用等，且因等级不同而使其售价不同，但尽管配戴口罩可避免吸入受污染的有害空气或以空气散布的流行病毒，但实际上口罩可避免吸入受污染的有害空气的功效相当有限，且配戴时因为密封式阻绝空气的方式，配戴者必需用力吸气才能得到充足的空气，使配戴时产生不舒适感，特别是在空气品质恶劣或空气稀少的地方配戴者将因闷热以及空气不足而感到不舒适，此也为口罩长久以来存在的问题。For a long time, in order to avoid inhaling polluted and harmful air, in addition to various air filtration and purification equipment used indoors, most of the outdoors and public places wear masks to avoid inhaling polluted and harmful air or air-dispersed epidemics. Viruses, and there are quite a lot of types of masks, which vary according to the required use and requirements. They are divided into general use, medical use, industrial use, epidemic area use and fire use, etc., and the price varies according to the grade. Different, but although wearing a mask can prevent inhalation of polluted harmful air or airborne epidemic viruses, in fact, the effectiveness of masks to prevent inhalation of polluted harmful air is quite limited, and when worn because of the airtight barrier In this way, the wearer must inhale hard to get enough air, which will cause discomfort when wearing it, especially in places with poor air quality or scarce air, the wearer will feel uncomfortable due to stuffy heat and insufficient air. It is also a problem that masks have existed for a long time.
