Embodiment Construction
[0026] The duckbill-shaped mask in the embodiment of the present invention is composed of an upper side 1 of the mask, a lower side 2 of the mask, an elastic band 5 of the mask, a bridge line of the nose 3, and an inner plastic film sheet 4 .
[0027] The upper side 1 of the mask and the lower side 2 of the mask are both inverted trapezoidal structures of the same shape and size; the upper side 1 of the mask has a built-in nose bridge line 3 near the top of the inverted trapezoid (that is, the opening surface of the mask); The inner plastic film sheet 4 is pasted on the upper part of the single side 1; the inner plastic film sheet 4 is only pasted on the lower side 2 of the mask; The edge of the open face of the face. The upper side 1 of the mask and the lower side 2 of the mask with the plastic film 4 are superimposed on each other; except for the open side, the attached figure 1 , 2 The A side shown in is not bonded, and the edges of the remaining positions are bonded as ...

A duckbilled-shaped respirator is characterized in that the respirator is composed of an upper single face (1) of the respirator, a lower single face (2) of the respirator, a fastening belt (5) of the respirator, a nose bridge line (3) and an inner plastic film sheet (4). The upper single face of the respirator and the lower single face of the respirator are both same in shapes and sizes and of an inverted-taper structure formed by overlapping two layers PP anti-sticking non-woven fabrics, a layer of 50g / m<2> melt-blow non-woven fabrics and a layer of ventilation films. The nose bridge line is built in the upper single face of the respirator, and the inner plastic film sheet is bonded with the upper single face and the lower single face of the respirator. The upper single face of the respirator and the lower single face of the respirator are overlapped, positions excepting for an upper side of the inverted taper are integrally bonded, and two ends of the fastening belt of the respirator are bonded with positions of two ends of an opening face of the respirator in a natural state without exogenous process. The duckbilled-shaped respirator can effectively filter particles in air and separate sprays, blood, body fluid and secreta. The duckbilled-shaped respirator is applicable to use of medical staff and health protection of the masses.
Description
[0001] Technical field [0002] The invention involves a duckbill mask and its preparation method, which is the field of sanitary materials technology. Background technique [0003] The mask has a certain filtering effect on the air entering the lungs. When the respiratory disease is popular, when operating in a polluted environment such as dust, wearing a mask has a very good effect. [0004] Masks include activated carbon masks, air filter masks and gas supply masks.Air filter masks are the most widely used categories in our daily work.For good protective masks, the following three conditions should be available. One is that the filter efficiency is high when the mask is well -tightly integrated with the user's facial facial facial, and the other is that the respiratory resistance is small, and the third is that the user feels comfortable.There are many materials for dust -proof mask filter materials, including ordinary fabrics, animal hair, non -woven fabrics, etc.The struct...
