Abstract

A mask apparatus includes a mask body and a mask body cover coupled to the mask body. The mask body includes a front surface, a rear surface, and a pair of air ducts disposed at left and right sides of the front surface. The mask body is configured to mount a pair of fan modules at suction sides of the pair of air ducts. The mask body cover covers the pair of air ducts and the pair of fan modules. The mask body defines a cover coupling groove along an edge of the mask body, and the cover coupling groove is coupled to an edge of the mask body cover.

First claim

What is claimed is:

1 . A mask apparatus comprising:
a mask body comprising:
a front surface,
a rear surface disposed at an opposite side of the front surface of the mask body, and
a pair of air ducts disposed at left and right sides of the front surface of the mask body, respectively, wherein the mask body is configured to mount a pair of fan modules at suction sides of the pair of air ducts, the pair of fan modules being configured to supply external air to the pair of air ducts; and
a mask body cover that is coupled to the mask body and covers the pair of air ducts and the pair of fan modules, wherein the mask body defines a cover coupling groove along an edge of the mask body, the cover coupling groove being coupled to an edge of the mask body cover.

2 . The mask apparatus according to claim 1 , wherein the mask body comprises:
a main body configured to be in contact with a face of a user; a bent portion that extends along an edge of the main body; and a cover coupling end that is bent from an end of the bent portion and that defines the cover coupling groove.

3 . The mask apparatus according to claim 2 , wherein the cover coupling end comprises a stepping portion that defines the cover coupling groove, and
wherein the edge of the mask body cover is inserted into the cover coupling groove.

4 . The mask apparatus according to claim 3 , wherein the cover coupling groove has an L-shaped cross-section or a V-shaped cross-section.

5 . The mask apparatus according to claim 1 , wherein each of the pair of air ducts defines a suction hole configured to receive a side surface of one of the pair of fan modules, the side surface defining an outlet of the one of the pair of fan modules.

6 . The mask apparatus according to claim 1 , wherein each of left and right sides of the rear surface of the mask body defines a cutoff portion, and
wherein at least a portion of the cutoff portion defines an outlet of one of the pair of air ducts.

7 . The mask apparatus according to claim 6 , further comprising:
a seal coupled to the rear surface of the mask body and configured to define a breathing space therein; and a sealing bracket that couples the seal to the rear surface of the mask body.

8 . The mask apparatus according to claim 7 , wherein the sealing bracket comprises:
a sealing insertion portion having a closed loop shape; and a bracket insertion portion that extends from an inner edge of the sealing insertion portion and is configured to cover a first portion of the cutoff portion, wherein the outlet is defined by a second portion of the cutoff portion outside of the first portion.

9 . The mask apparatus according to claim 8 , wherein the bracket insertion portion defines a rear surface of the one of the pair of air ducts, and
wherein the outlet is configured to communicate with the breathing space.

10 . The mask apparatus according to claim 1 , wherein the mask body further comprises an air discharge portion that protrudes from the front surface of the mask body and has a tunnel shape.

11 . The mask apparatus according to claim 10 , wherein the air discharge portion includes a curved surface or a plurality of bent sections defining the tunnel shape.

12 . The mask apparatus according to claim 10 , wherein the mask body further comprises a rib that extends forward from a lower end of the mask body, and
wherein the cover coupling groove is defined along an end of the rib.

13 . The mask apparatus according to claim 12 , wherein the mask body defines:
a first air exhaust hole at a lower portion of the mask body; and a second air exhaust hole that is disposed below the first air exhaust hole and passes through the rib.

14 . The mask apparatus according to claim 13 , wherein the air discharge portion surrounds the first air exhaust hole,
wherein the air discharge portion has a left lower end and a right lower end that are connected to a top surface of the rib, and wherein the left lower end and the right lower end of the air discharge portion define a left edge and a right edge of the second air exhaust hole, respectively.

15 . The mask apparatus according to claim 13 , further comprising a check valve configured to selectively block the first air exhaust hole.

16 . The mask apparatus according to claim 15 , wherein the check valve is spaced apart from the second air exhaust hole.

17 . The mask apparatus according to claim 15 , further comprising a check valve cover that extends from the rear surface of the mask body cover to an inner space of the air discharge portion.

18 . The mask apparatus according to claim 17 , wherein the check valve cover comprises:
a main cover that horizontally extends toward the mask body and supports an upper end of the check valve; and an auxiliary cover that extends downward from each of ends of the main cover.

19 . The mask apparatus according to claim 18 , wherein the auxiliary cover is in contact with an inner surface of the air discharge portion.

20 . The mask apparatus according to claim 10 , wherein a rear surface of the mask body cover covers an opened front surface of the air discharge portion.
