Abstract

A mask apparatus includes a mask body that defines a suction hole and a discharge hole, a face guard coupled to a rear surface of the mask body and configured to contact a face of a user, and an air cleaning module filter external air and to supply the filtered air into a breathing space in the face guard. The face guard includes a coupling portion that faces the rear surface of the rear body, a close contact portion configured to be in contact with the face of the user, a connection portion that connects the coupling portion to the close contact portion and defines one or more widths of the face guard in a front-rear direction, and a spacing protrusion that protrudes from an outer surface of the connection portion to thereby separate at least a portion of the connection portion from the suction hole.

First claim

What is claimed is:

1 . 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 coupled to a rear surface of the rear body 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 into the breathing space, wherein the face guard comprises:
a coupling portion that faces the rear surface of the rear body,
a close contact portion configured to be in contact with the face of the user,
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, and
a spacing protrusion that protrudes from an outer surface of the connection portion to thereby separate at least a portion of the connection portion from the suction hole.

2 . The mask apparatus according to claim 1 , wherein the spacing protrusion has a convex shape or a rounded shape.

3 . The mask apparatus according to claim 1 , wherein the spacing protrusion extends along the outer surface of the connection portion in the front-rear direction.

4 . The mask apparatus according to claim 3 , wherein a length of the spacing protrusion in the front-rear direction is equal to one of the one or more widths of the connection portion.

5 . The mask apparatus according to claim 1 , wherein the spacing protrusion is one of a plurality of spacing protrusions that are spaced apart from one another.

6 . The mask apparatus according to claim 5 , wherein the plurality of spacing protrusions extend in parallel to one another.

7 . The mask apparatus according to claim 5 , wherein the plurality of spacing protrusions are spaced apart from one another in a vertical direction crossing the front-rear direction.

8 . The mask apparatus according to claim 5 , wherein the plurality of spacing protrusions comprise:
a first protrusion disposed at a lower part of the connection portion, the first protrusion having a first length in the front-rear direction; and a second protrusion disposed above the first protrusion, the second protrusion having a second length in the front-rear direction greater than the first length.

9 . The mask apparatus according to claim 8 , wherein the plurality of spacing protrusions further comprise:
a third protrusion disposed above the second protrusion, the third protrusion having a third length in the front-rear direction greater than the second length.

10 . The mask apparatus according to claim 1 , wherein the air cleaning module comprises:
a filter housing that is disposed at the rear body and is in fluid communication with the suction hole, the filter housing being configured to accommodate a filter disposed at the suction hole.

11 . The mask apparatus according to claim 10 , wherein the filter housing comprises:
a filter frame configured to surround a side surface of the filter; and a filter cover disposed at a rear surface of the filter frame, the filter cover defining a suction grille that is in fluid communication with the suction hole.

12 . The mask apparatus according to claim 11 , wherein the spacing protrusion is disposed at a position corresponding to the filter cover.

13 . The mask apparatus according to claim 12 , wherein the spacing protrusion is one of a plurality of spacing protrusions that are spaced apart from one another in a vertical direction crossing the front-rear direction, and
wherein the plurality of spacing protrusions comprise:
a first protrusion facing a lower end of the filter cover; and
a second protrusion that is disposed above the first protrusion in the vertical direction and faces a middle portion of the filter cover disposed above the lower end of the filter cover.

14 . The mask apparatus according to claim 13 , wherein the first protrusion has a first length in the front-rear direction, and
wherein the second protrusion has a second length in the front-rear direction greater than the first length.

15 . The mask apparatus according to claim 14 , wherein the plurality of spacing protrusions further comprise a third protrusion that is disposed above the second protrusion in the vertical direction and faces an upper end of the filter cover, the third protrusion having a third length in the front-rear direction greater than the second length.

16 . The mask apparatus according to claim 1 , wherein the suction hole is defined outside the breathing space, and the discharge hole is defined inside the breathing space.

17 . The mask apparatus according to claim 16 , wherein the suction hole is one of a plurality of suction holes comprising:
a left suction hole defined at a left side of the face guard; and a right suction hole defined at a right side of the face guard, and wherein the spacing protrusion is one of a plurality of spacing protrusions comprising:
a left protrusion that protrudes from a left surface of the connection portion at the left side of the face guard, and
a right protrusion that protrudes from a right surface of the connection portion at the right side of the face guard.

18 . The mask apparatus according to claim 1 , wherein the face guard separates the discharge hole from the suction hole.

19 . The mask apparatus according to claim 18 , wherein the outer surface of the connection portion faces and is exposed to the air cleaning module, and
wherein an inner surface of the connection portion is defined at an opposite side of the outer surface of the connection portion and faces the breathing space.

20 . The mask apparatus according to claim 1 , wherein the rear body defines the suction hole, the front body covering a front side of the suction hole, and
wherein the air cleaning module comprises:
a fan disposed at the suction hole; and
a filter housing disposed rearward relative to the fan and configured to accommodate a filter, the filter housing defining a suction grille that is in fluid communication with the suction hole.
