The beneficial effect of present technique: during use, the medial branch of barrier film is attached to people's face, (use with the better soft resin of human body compatibility and make) is because people's nostril difference in size is bigger, so concentric reducer nose conduit is made big or small capitiform, to adapt to the use of nostril size, concentric reducer nose conduit small end partly stretches in people's the nostril, along with the variation of inserting the nostril degree of depth, diameter is also increasing, and concentric reducer nose conduit and nostril wall are combined closely, thereby have sealed inner air and outer air.Air by respiratory, through concentric reducer nose conduit, the outside air flue that arrives barrier film enters filter course, and filter course can increase area and density arbitrarily, enough big filter area and density are arranged, can filter, purify the breathe air that contains airborne dust, flue dust, chemical peculiar smell, carries disease germs effectively.Inboard owing to can not enter barrier film by the gas of respiratory that is to say that the gas that does not have breathing turns back to face, does not also have the water vapour wet skin, does not have sticky feeling; Like this, the people who wears glasses is when using this nose catheter type mouth mask, and the gas of breathing can not arrive lens by the space between face and the barrier film, so lens can be because of no steam, it is clear to remain.
Above-mentioned nose catheter type mouth mask, the peripheral projection of barrier film, filter course embeds in the projection.Embedding or replacing filter course are very convenient.It also comprises and is arranged on the cover plate that has a plurality of ventilative through holes on the projection; Filter course is between cover plate and support column.The cover plate periphery is pressed on salable filter course periphery on the projection, does not allow contaminated air directly enter in the nose from peripheral slit, owing on the air flue many support columns are arranged, cover plate compresses filter course, and also not influence filter course ventilative; Can beautify the mouth mask appearance again.
Above-mentioned nose catheter type mouth mask, barrier film and concentric reducer nose conduit, support column are one.
Above-mentioned nose catheter type mouth mask, barrier film profiling and people's face curve, its middle face laterally protrudes, the inside edgewise bend in both sides, has formed the curve with the fine combination of people's face curved surface.Like this, barrier film can be better and the human face fit.
Above-mentioned nose catheter type mouth mask, barrier film is the resin barrier film.Resin barrier film quality softness has on comfortable.
