  • FIG. 2 is a schematic diagram illustrating a mask body according to an exemplary embodiment of the present invention.
  • a mask 100 includes a mask body 10, an inhalation module 20, and an exhalation module 30.
  • the inhalation module 20 performs a function of an inflow passage in which outside air is injected when inhaling upon using the mask 100
  • the exhalation module 30 performs a function of a discharge passage in which air is discharged to the outside when exhaling.
  • the mask body 10 performs a function of supporting the inhalation module 20 and the exhalation module 30, and the mask body 10 is formed to have a predetermined curvature to close contact with a face when using the mask 100, thereby enabling outside air not to be injected to a periphery of the mask 100.
  • the exhalation module 30 is formed in a central portion of the mask 100, and the inhalation module 20 is formed in symmetry at both sides of the mask 100 based on the exhalation module 30.
  • the exhalation module 30 is disposed adjacent to respiratory organs, i.e., a nose and a mouth, when the user exhales, discharge air does not stay for a long time period within the mask 100 and is rapidly discharged to the outside of the mask 100.
  • an inhalation module inserting port 12 and an exhalation module inserting port 13 for inserting the inhalation module 20 and the exhalation module 30, respectively, are formed. Diameters of the inhalation module inserting port 12 and the exhalation module inserting port 13 are formed identical to exterior diameters of the inhalation module 20 and the exhalation module 30, and thus the inhalation module inserting port 12 and the exhalation module inserting port 13 are inserted by forced insertion.

That is, when the user wear the mask 100 and breathes, inhalation and exhalation are injected and discharged through the inhalation module 20 and the exhalation module 30, respectively, and air is not injected and ejected through the mask body 10 and thus a virus can be effectively intercepted.
  • the mask body 10 includes an adhesive module 11 that is formed along an edge of the mask body 10.
  • the adhesive module 11 is formed with a double-sided adhesive tape that may be easily attached to and removed from a skin, and the mask 100 close contacts with a face through the adhesive module 11. Because outside air is not injected into or ejected from the periphery of the mask 100 due to a configuration of the adhesive module 11, air is injected and discharged through the inhalation module 20 and the exhalation module 30.
