Embodiment Construction

[0009] according to figure 1 The main body (1) of the breathing mask made of medical silicone is attached to the skin around the mouth and nose of the human face to form a partially enclosed space. The space formed by the arc-shaped cup prevents the mouth and nose from directly touching the mask wall while meeting hygiene, comfort needs. Under the arc-shaped cover wall, open a cover main hole (6) with a standard aperture. The aperture is slightly smaller than the diameter of the card (2) of the detachable and assembled card filter element made of medical plastic, and the medical plastic is fixed by the stretching elasticity of silica gel. Make the card (2) of the card-type filter element that can be assembled and disassembled, and seal the edges. A replaceable filter element and a filter material (3) are fixed in the card (2) of the card type filter element which is made of medical plastic and can be assembled and disassembled. When changing the filter element, the card (2) ...

Abstract

The invention discloses a multipurpose epidemic prevention mask which can be stored for a long time, can be quickly produced in a special period and can increase the supply amount of replaceable filter element filter materials. According to the technology, the telescopic elasticity of medical silica gel is used for being attached to the face, and the replaceable filter element is fixed. A breathing mask main body is manufactured by utilizing the hygienic characteristics that medical silica gel can be stored for a long time, used for multiple times and convenient to clean and disinfect; and a card type filter element that is simple in main production process and high in raw material utilization rate is produced in a special period. The supply pressure is reduced in a special period, and theallocating efficiency is improved. The specific filter element position of the multipurpose breathing mask can guide an exhaled air flow to automatically sink, the area of the filter element making contact with droplet foreign matters on the same layer is reduced, and the resistance of the flat-shot foreign matter is increased. The penetrating power of the droplets is reduced. And the probabilityof cross infection is reduced; and when epidemic diseases occur frequently, epidemic prevention and disease prevention of groups are carried out in the places where the epidemic diseases occur frequently.

Description

technical field [0001] This design involves a multi-purpose anti-epidemic mask that can replace various filter materials and filter elements in time during the epidemic prevention period to help filter harmful substances when breathing. Background technique [0002] The basic form of the mask since it is used for the general population to prevent epidemic diseases is to cover the mouth, nose and its surrounding parts with a large piece of filter material that can filter foreign matter. With the development of social economy and the change of people's living habits, masks all over the world have basically become a disposable disposable appliance. Various standards at home and abroad are basically divided according to the filtration performance of the filter element material. In January 2020, the epidemic caused by the new coronavirus in my country caused a shortage of anti-epidemic masks and medical masks. Even if global Chinese purchase globally and factories across the co...
