Abstract

A mask apparatus includes a mask body including an air duct disposed at a front surface of the mask body, and a fan module mounting portion disposed at a suction-side of the air duct, a fan module disposed at the fan module mounting portion and configured to supply external air to the air duct, a mask body cover that is coupled to the front surface of the mask body and covers the fan module and the air duct, a seal coupled to a rear surface of the mask body and configured to contact a user's face and define a breathing space for the user, a sealing bracket that fixes a portion of the seal to the rear surface of the mask body, and a pad configured to be disposed inside the breathing space.

First claim

What is claimed is:

1 . A mask apparatus comprising:
a mask body comprising an air duct disposed at a front surface of the mask body, and a fan module mounting portion disposed at a suction-side of the air duct; a fan module disposed at the fan module mounting portion and configured to supply external air to the air duct; a mask body cover that is coupled to the front surface of the mask body and covers the fan module and the air duct; a seal coupled to a rear surface of the mask body and configured to contact a user's face and define a breathing space for the user; a sealing bracket that fixes a portion of the seal to the rear surface of the mask body; and a pad configured to be disposed inside the breathing space.

2 . The mask apparatus according to claim 1 , wherein the pad defines an air-passing portion.

3 . The mask apparatus according to claim 2 , wherein the air-passing portion comprises:
a first air-passing portion configured to supply the external air introduced into the breathing space through the air duct to the user; and a second air-passing portion configured to discharge air exhaled by the user to an outside of the breathing space.

4 . The mask apparatus according to claim 3 , wherein the first air-passing portion comprises a plurality of opening holes that are defined above the second air-passing portion, and
wherein the second air-passing portion comprises (i) a groove that is recessed toward the first air-passing portion from a lower end of the pad, or (ii) a hole that passes through a lower region of the pad.

5 . The mask apparatus according to claim 4 , wherein the first air-passing portion comprises:
a left air-passing portion defined at a left region of the pad with respect to a position of the seal; and a right air-passing portion defined at a right region of the pad with respect to the position of the seal.

6 . The mask apparatus according to claim 1 , wherein the seal comprises:
a coupling portion that is pressed by the sealing bracket and coupled to the mask body; a side surface portion that extends from the coupling portion rearward relative to the rear surface of the mask body; and a contact portion that is curved or bent from an end of the side surface portion and extends toward the coupling portion, and wherein an edge of the pad is disposed in a space defined between the side surface portion and the contact portion.

7 . The mask apparatus according to claim 6 , wherein the pad is configured to be detached from the breathing space.

8 . The mask apparatus according to claim 7 , wherein the edge of the pad defines a size of the pad, and is configured to contact an inner surface of the side surface portion.

9 . The mask apparatus according to claim 6 , wherein the edge of the pad is configured to couple to an inner surface of the side surface portion, or the pad and the side surface portion are parts of one body.

10 . The mask apparatus according to claim 6 , wherein the pad is configured to couple to the sealing bracket, or the pad and the sealing bracket are parts of one body.

11 . The mask apparatus according to claim 10 , wherein the sealing bracket comprises:
a first sealing support configured to bring the coupling portion into contact with the rear surface of the mask body; and a second sealing support disposed at an inner edge of the first sealing support.

12 . The mask apparatus according to claim 11 , wherein the second sealing support extends in a direction crossing the first sealing support and supports an inner edge of the coupling portion.

13 . The mask apparatus according to claim 12 , wherein the pad is provided in one body with the first sealing support or the second sealing support.

14 . The mask apparatus according to claim 3 , wherein the mask body defines:
an air outlet configured to supply air blown by the fan module to the breathing space; and air exhaust holes configured to discharge air exhaled by the user to the outside of the breathing space, wherein the first air-passing portion is defined at a position corresponding to the air outlet, and wherein the second air-passing portion is defined at a position corresponding to each of the air exhaust holes.

15 . The mask apparatus according to claim 1 , wherein the mask body cover defines:
a filter mounting portion that is recessed from a front surface of the mask body cover; and an air suction hole that is defined inside the filter mounting portion.

16 . The mask apparatus according to claim 15 , wherein the filter mounting portion comprises:
a first filter mounting portion defined at a right side of the mask body cover with respect to a position of the seal; and a second filter mounting portion defined at a left side of the mask body cover with respect to the position of the seal.

17 . The mask apparatus according to claim 16 , further comprising:
a first filter and a second filter, each of the first filter and the second filter being configured to be accommodated in the first filter mounting portion or the second filter mounting portion; a first filter cover coupled to the first filter mounting portion and configured to cover the first filter, the first filter cover defining one or more first air inlets at a side surface of the first filter cover; and a second filter cover coupled to the second filter mounting portion and configured to cover the second filter, the second filter cover defining one or more second air inlets at a side surface of the second filter cover.

18 . The mask apparatus according to claim 16 , wherein the first filter cover or the second filter cover defines a filter cover opening, and comprises a manipulation portion disposed at the filter cover opening.

19 . The mask apparatus according to claim 1 , wherein the mask body defines a cover coupling groove at an edge of the front surface of the mask body, the cover coupling groove receiving an edge of the mask body cover.

20 . The mask apparatus according to claim 1 , further comprising:
hook mounting portions disposed side ends of the mask body; and bands, each of the bands being connected to one of the hook mounting portions and configured to surround an occipital region of the user or an ear of the user.
