Abstract

A mask device includes a mask body including a front cover to form an outer appearance of the mask body, a frame coupled to the front cover, the frame located in front of a user's nose and mouth when the mask device is worn by the user, the frame including at least one inlet and at least one outlet located below the inlet, and a partition plate between the frame and the front cover, the partition plate forming an upper space and a lower space in the mask body. A first air cleaner is coupled to one side of the mask body and a second air cleaner is coupled to an other side of the mask body, where the first air cleaner and the second air cleaner filters outside air sucked in from an outside environment and supplies the filtered air to the mask body. The upper space of the mask body is in communication with the first air cleaner, the second air cleaner, and the at least one inlet, and the lower space of the mask body is in communication with the at least one outlet.

First claim

What is claimed is:

1. A mask device comprising:
a mask body including
a front cover to form an outer appearance of the mask body,
a rear cover coupled to the front cover to define a space between the rear cover and the front cover, the rear cover located in front of a user's nose and mouth when the mask device is worn by the user, the rear cover including at least one inlet and at least one outlet located below the inlet, and
at least one partition plate disposed between the rear cover and the front cover, the at least one partition plate includes a first partition plate and a second partition plate, the first partition plate being disposed above the second partition plate and the second partition plate being disposed to partition the space between the rear cover and the front cover into an upper space and a lower space, and
a first air cleaner and a second air cleaner to filter outside air sucked in from an outside environment and to supply the filtered air to the upper space of the mask body, the first air cleaner coupled to one side of the mask body and the second air cleaner coupled to an other side of the mask body,
wherein the upper space of the mask body is in communication with the first air cleaner, the second air cleaner, and the at least one inlet, and the lower space of the mask body is in communication with the at least one outlet.

2. The mask device of claim 1 , wherein
the upper space of the mask body includes
a first flow passage disposed at the one side of the mask body through which the filtered air of the first air cleaner flows toward the at least one inlet, and
a second flow passage disposed at the other side of the mask body through which the filtered air of the second air cleaner flows toward the at least one inlet.

3. The mask device of claim 2 , wherein
the at least one inlet includes a first inlet and a second inlet, and
the upper space includes at least one inflow guide to separate the first flow passage and the second flow passage,
wherein the first flow passage flows the filtered air of the first air cleaner to the first inlet and the second flow passage flows the filtered air of the second air cleaner to the second inlet.

4. The mask device of claim 3 , wherein
the at least one inflow guide includes a first inflow guide and a second inflow guide, the first inflow guide is inclined towards the first inlet, and the second inflow guide is inclined towards the second inlet.

5. The mask device of claim 4 , wherein the first inlet and the second inlet are disposed at the rear cover in front of the user's nose when the mask device is worn by the user.

6. The mask device of claim 2 , wherein
the first air cleaner includes a first suction opening and a first air flow hole; and
the second air cleaner includes a second suction opening and a second air flow hole, wherein the outside air is sucked in through the respective first suction opening and second suction opening, the filtered air from the first air cleaner flows from the first air flow hole towards the first passage, and the filtered air from the second air cleaner flows from the second air flow hole towards the second passage.

7. The mask device of claim 6 , further comprising:
a first air duct to couple the first air flow hole to the first passage; and
a second air duct to couple the second air flow hole to the second passage.

8. The mask device of claim 1 , wherein the at least one outlet includes a plurality outlets disposed at the rear cover in front of the user's mouth when the mask device is worn by the user.

9. The mask device of claim 1 , wherein
the mask body includes at least one discharge port to discharge air from the lower space of the mask body to the outside environment, the at least one discharge port is coupled to the at least one outlet through the lower space.

10. The mask device of claim 9 , wherein the at least one discharge port disposed at the mask body discharges the air from the lower space vertically from the mask body.

11. The mask device of claim 9 , wherein at least one of the at least one outlet and the at least one discharge port includes a check valve.

12. The mask device of claim 1 , further comprising a packing disposed at an outer circumferential surface of the rear cover.

13. The mask device of claim 12 , wherein a portion of the packing that is located at the user's nose when the mask device is worn by the user has a thickness thicker than a thickness of a remaining portion of the packing.

14. A mask device comprising:
a mask body includes
a front cover,
a rear cover coupled to the front cover to define a space between the rear cover and the front cover, and defining a breathing space in which a user's nose and mouth are positioned when the mask device is worn by the user,
at least one partition plate disposed between the rear cover and the front cover, the at least one partition plate includes a first partition plate and a second partition plate, the first partition plate being disposed above the second partition plate and the second partition plate being disposed to partition the space between the rear cover and the front cover into an upper space and a lower space,
a first air cleaner and a second air cleaner to filter outside air sucked in from an outside environment and to supply the filtered air to the upper space of the mask body; and
a first fixing part and a second fixing part, the first fixing part coupling the first air cleaner to one side of the mask body, and the second fixing part coupling the second air cleaner to an other side of the mask body,
wherein the mask body further including at least one inlet disposed at the rear cover and in communication with the upper space, at least one outlet disposed at the rear cover and in communication with the lower space, and at least one discharge port disposed at the mask body and in communication with the lower space.

15. The mask device of claim 14 , wherein the at least one inlet is disposed in front of the user's nose and the at least one outlet is disposed in front of the user's mouth when the mask device is worn by the user.

16. The mask device of claim 14 , wherein
the at least one inlet includes a first inlet and a second inlet;
the mask body includes a first passage and a second passage at the upper space, the first passage is in communication with the first fixing part and the second passage is in communication with the second fixing part; and
a first inflow guide and a second inflow guide at the upper space, the first inflow guide to guide a flow of air in the first passage to the first inlet, and the second inflow guide to guide a flow of air in the second passage to the second inlet.

17. The mask device of claim 16 , further comprising:
a first duct at the first fixed part, wherein the filtered air of the first air cleaner is supplied to the first passage of the mask body through the first duct; and
a second duct at the second fixed part, wherein the filtered air of the second air cleaner is supplied to the second passage of the mask body through the second duct.

18. The mask device of claim 14 , wherein at least one of the at least one outlet and the at least one discharge port includes a check valve.
