The specific implementation mode is as follows:
the utility model discloses a realize through following mode:
the utility model provides a do not reveal safe gauze mask includes lower floor's filter cloth 1, upper filter cloth 2, nasal obstruction component 3, and lower floor's filter cloth 1 and upper filter cloth 2 are in the same place through respective periphery border interconnect to form a filter chamber between the two, nasal obstruction component 3 is fixed on anterior aperture 22 position in upper filter cloth 2, the utility model discloses the gauze mask is that the nose stopper head 31 on through the gauze mask blocks up the nostril and realizes that the gas in the respiratory track passes through nasal obstruction pipe 32 and with the gaseous interchange in the filter chamber.
The lower-layer filter cloth 1 is a concave surface, and two ends of the two ear ropes 11 are connected with the left outer side surface and the right outer side surface of the lower-layer filter cloth 1.
The upper layer of filter cloth 2 is a concave surface, the front part of the concave surface is provided with two filter cloth straight line joints 21, the filter cloth near the inner ends of the filter cloth straight line joints 21 is provided with two small holes 22 with the same size, and the upper layer of filter cloth 2 is positioned above the lower layer of filter cloth 1.
The nose plug member 3 is composed of two nose plug heads 31, two nose plug catheters 32, two support plates 33 and an extrusion support body 34, the nose plug head 31 which is approximately in the shape of a circular truncated cone is made of soft material, the middle part of the nose plug member is provided with a vent hole 311, the lower side surface of the nose plug head 31 is tightly close to the upper side surface of the lower support plate 33, the lower part of the nose plug catheter 32 is provided with a hose 321, the upper part of the nose plug catheter is provided with a hard tube 322, the upper end of the hose 321 is sleeved on the lower end of the hard tube 322, the middle part of the nose plug member 3 is provided with two rectangular support plates 33, the support plate 33 is provided with two round holes 331, the upper layer filter cloth 2 is clamped between the two support plates 33, the two small holes 22 on the upper layer filter cloth 2 are the same as the two round holes 331 on the support plate 33 in size and are superposed in position, the extrusion support, the upper parts of the hoses 321 are respectively positioned in the round holes 331 of the upper and lower supporting plates 33 and the small holes 22 of the upper layer filter cloth 2.
