Mask apparatus

A mask apparatus comprising:

• a mask body that defines a suction hole configured to receive external air from an outside of the mask apparatus and a discharge hole configured to discharge air to the outside, the mask body comprising a rear body and a front body that is coupled to a front surface of the rear body;
• a face guard detachably coupled to a rear surface of the rear body by magnetic force and configured to be in contact with a face of a user, the face guard defining a breathing space;
• and
• an air cleaning module disposed at the rear body and configured to filter the external air received through the suction hole and to supply the filtered air to the breathing space, the air cleaning module comprising a filter housing configured to accommodate a filter,
• wherein the face guard comprises:
• a coupling portion that faces the rear surface of the rear body,
• a plurality of magnetic bodies disposed at a front surface of the coupling portion,
• a close contact portion configured to be in contact with the face of the user, and
• a connection portion that connects the coupling portion to the close contact portion, the connection portion defining one or more widths of the face guard in a front-rear direction,
• wherein the plurality of magnetic bodies comprise:
• a first magnetic body disposed at an upper portion of the front surface of the coupling portion, the first magnetic body being disposed at a center of the upper portion of the front surface of the coupling portion, and
• a second magnetic body and a third magnetic body that are disposed at a lower portion of the front surface of the coupling portion, the second and third magnetic bodies being spaced apart from each other and disposed at sides of a center of the lower portion of the front surface of the coupling portion, respectively,
• wherein the face guard defines a plurality of magnetic body mounting portions that receive the plurality of magnetic bodies, respectively,
• wherein each of the plurality of magnetic body mounting portions comprises:
• a mounting portion body that protrudes forward from the front surface of the coupling portion toward one of a plurality of magnet mounting grooves of the rear body, and
• an insertion guide rib disposed inside the mounting portion body, and
• wherein the mounting portion body and the insertion guide rib are spaced apart from each other to thereby define an insertion hole that receives one of the plurality of magnetic bodies between the mounting portion body and the insertion guide rib.
