This invention discloses a miniature glasses-style
nasal mask, relating to the field of respiratory protective equipment. The
nasal mask includes: a frame, an inner tube, an outer tube, filter cotton, a fixing cap, and a one-way valve. The frame is integrally formed in a sheet shape. The two temples form an angle of ≤15 degrees with the inner tube to clamp the sides of the
nose, and the two inner tubes clamp the
nasal septum, working together to ensure the
nasal mask fits snugly and is not easily dislodged. The inner and outer tubes are located on the inner and outer sides of the frame, coaxial, and integrally connected. A one-way valve is located inside a thin tube with a cover and side holes protruding from the
root surface of the outer tube. The inner tube is short and fitted with a thin latex tube, which is inserted into the
nostril and seals the
nasal cavity. The filter cotton is conventional, round, and has the same cross-section as the outer tube opening. The fixing cap presses the filter cotton to seal the outer tube opening and is preferably fixed to the outer tube opening by screwing. A round hole is opened at the center of the cap. Beneficial effects: Air is inhaled through the filter cotton and exhaled through the one-way valve, ensuring unobstructed
breathing; easy to seal and fill, the whole structure is not easily dislodged, miniature and simple, with a simple structure and low cost.
