Description
Technical Field
The utility model relates to a medical protection field, especially a nanometer melt-blown fabric environmental protection gauze mask that air resistance is low.
Background
The mask is a sanitary article, generally refers to a device which is worn at the mouth and nose part and used for filtering air entering the mouth and nose so as to prevent harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer, and is made of gauze or paper and the like. The mask has a certain filtering function on air entering the lung, and has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like.
The body of the medical mask used at present adopts multilayer melt-blown cloth to stack, and particles, viruses and droplets in the air are blocked by the melt-blown cloth, so that the effect of preventing infectious diseases is achieved. The mask in the prior art has the following defects: (1) the mask is attached to the face, so that a good germ separation effect can be achieved, and meanwhile, due to the fact that the melt-blown cloth is good in air tightness, particularly when the mask exhales, the air resistance of the mouth and the nose of a person is high when the mask breathes, and the mask is not smooth in breathing. When the check valve is attached to the mask, the air resistance is low, but the cost is high, which is not favorable for widespread use. (2) When infectious diseases (particularly respiratory infectious diseases) are prevalent, masks are not in demand in the market and are in shortage as a means for effective protection. Under the condition of the mask lacking rapidly, people need to keep the mask taken off properly when having meals, cleaning faces and having a short rest so as to be reused later, but due to the particularity of the mask, the inner side of the mask is in contact with the mouth and the nose and cannot be placed at will, if bacteria are adhered, the health of a human body is directly harmed, and therefore the mask which is rapid and convenient to store needs to be developed.
