Abstract

A mask apparatus including a mask body that defines a communication hole, a sensor mounting portion that extends from a front surface of the mask body, that surrounds the communication hole, and that defines an installation space therein, a seal coupled to a rear surface of the mask body and configured to define a breathing space between the mask body and a user, a pressure sensor accommodated in the installation space and configured to sense air pressure inside the breathing space that is in communication with the communication hole, and a film disposed in the installation space and configured to restrict permeation of moisture from the breathing space into the installation space through the communication hole.

First claim

What is claimed is:

1 . A mask apparatus comprising:
a mask body that defines a communication hole; a sensor mounting portion that extends from a front surface of the mask body and surrounds the communication hole, the sensor mounting portion defining an installation space therein; a seal coupled to a rear surface of the mask body and configured to define a breathing space between the mask body and a user; a pressure sensor accommodated in the installation space and configured to sense air pressure inside the breathing space that is in communication with the communication hole; and a film disposed in the installation space and configured to restrict permeation of moisture from the breathing space into the installation space through the communication hole.

2 . The mask apparatus according to claim 1 , wherein the film comprises a porous film.

3 . The mask apparatus according to claim 2 , wherein the film further comprises an edge portion disposed along an edge of the porous film.

4 . The mask apparatus according to claim 3 , wherein the sensor mounting portion comprises a seating surface that is disposed at an inside of the sensor mounting portion and supports the edge portion of the film.

5 . The mask apparatus according to claim 1 , wherein the film is disposed between the pressure sensor and the communication hole.

6 . The mask apparatus according to claim 1 , wherein the sensor mounting portion comprises:
a first portion that extends forward from the front surface of the mask body; a pair of second portions that extend downward from ends of the first portion; and a third portion that connects lower ends of the pair of second portions to each other.

7 . The mask apparatus according to claim 6 , wherein the third portion comprises an inclined portion that is inclined with respect to the front surface of the mask body and that extends toward the first portion.

8 . The mask apparatus according to claim 7 , wherein the communication hole is disposed closer to the third portion than to the first portion.

9 . The mask apparatus according to claim 6 , further comprising a sensor sealing member configured to apply pressure to the film.

10 . The mask apparatus according to claim 9 , wherein the sensor sealing member comprises:
a cover portion that covers an opening defined at a front surface of the sensor mounting portion; and an extension portion that extends from a rear surface of the cover portion and is configured to apply pressure to the film.

11 . The mask apparatus according to claim 10 , wherein an outer surface of the extension portion is in contact with an inner surface of the sensor mounting portion.

12 . The mask apparatus according to claim 10 , further comprising a control substrate mounted on the mask body and configured to apply pressure to the cover portion,
wherein the pressure sensor is mounted on a rear surface of the control substrate.

13 . The mask apparatus according to claim 12 , wherein the cover portion defines a sensor opening that receives the pressure sensor.

14 . The mask apparatus according to claim 12 , further comprising a support rib that extends from the front surface of the mask body, the support rib comprising a hook disposed at an end of the support rib and configured to apply pressure to an upper end of the control substrate.

15 . The mask apparatus according to claim 1 , further comprising a mask body cover that is coupled to the front surface of the mask body and covers the pressure sensor.

16 . The mask apparatus according to claim 1 , further comprising:
a pair of fan modules mounted at a left side and a right side of the front surface of the mask body, respectively; and a pair of air ducts disposed on the front surface of the mask body, each of the pair of air ducts being disposed at an outlet side of one of the pair of fan modules, wherein the mask body defines a plurality of air outlets in the rear surface of the mask body, the plurality of air outlets being in communication with the outlet sides of the pair of air ducts.

17 . The mask apparatus according to claim 16 , wherein the plurality of air outlets comprise a pair of air outlets that are spaced apart from each other in a horizontal direction, and
wherein the communication hole is defined at a position in a horizontal line that passes through upper ends of the pair of air outlets.

18 . The mask apparatus according to claim 16 , wherein the communication hole is defined at a position in a vertical line that bisects the mask body into left and right sides.

19 . The mask apparatus according to claim 18 , wherein the plurality of air outlets comprise a pair of air outlets that are spaced apart from each other in a horizontal direction, and
wherein the communication hole is defined at an intersection between the vertical line and a horizontal line that passes through upper ends of the pair of air outlets.

20 . The mask apparatus according to claim 16 , wherein the plurality of air outlets comprise a pair of air outlets that are defined in the breathing space.
