Abstract

A mask apparatus includes a mask body, a pair of hook mounting portions at side ends of the mask body, a seal coupled to a rear surface of the mask body, and a pair of ear hook portions connected to the hook mounting portions. Each hook mounting portion includes an upper hook mounting portion, a lower hook mounting portion below the upper hook mounting portion, a hook pin at each of the upper hook mounting portion and the lower hook mounting portion, and a through-hole defined in each of the upper hook mounting portion and the lower hook mounting portion. Each ear hook portion includes a strap portion, a first hook portion connecting the strap portion to one of the upper and lower hook mounting portions, and a second hook portion connecting the strap portion to the other of the upper and lower hook mounting portions.

First claim

What is claimed is:

1 . A mask apparatus comprising:
a mask body; a pair of hook mounting portions that are disposed at side ends of the mask body, respectively; a mask body cover coupled to a front surface of the mask body; a seal coupled to a rear surface of the mask body and configured to define a breathing space therein; and a pair of ear hook portions that are configured to be connected to the pair of hook mounting portions, respectively, wherein each of the pair of hook mounting portions comprises:
an upper hook mounting portion disposed at one of the side ends of the mask body,
a lower hook mounting portion disposed at the one of the side ends of the mask body and positioned vertically below the upper hook mounting portion,
a hook pin disposed at each of the upper hook mounting portion and the lower hook mounting portion, and
a through-hole defined in each of the upper hook mounting portion and the lower hook mounting portion, and wherein each of the pair of ear hook portions comprises:
a strap portion,
a first hook portion configured to connect a first end of the strap portion to one of the upper hook mounting portion or the lower hook mounting portion, and
a second hook portion configured to connect a second end of the strap portion to the other of the upper hook mounting portion or the lower hook mounting portion.

2 . The mask apparatus according to claim 1 , wherein each of the first hook portion and the second hook portion comprises:
a hook body having a cylindrical shape, the hook body being configured to be coupled to the hook pin; and a hook extension portion that extends from an outer circumferential surface of the hook body.

3 . The mask apparatus according to claim 2 , wherein the hook body defines:
a hook groove configured to receive the hook pin; and a guide opening that is recessed from the outer circumferential surface of the hook body configured to guide the hook pin to the hook groove.

4 . The mask apparatus according to claim 3 , wherein a first width of the guide opening at the hook groove is less than a second width of the guide opening at the outer circumferential surface of the hook body.

5 . The mask apparatus according to claim 3 , wherein at least a portion of the hook body is configured to be accommodated in the through-hole.

6 . The mask apparatus according to claim 5 , wherein a width of the through-hole corresponds to an outer diameter of the hook body, and
wherein a length of the through-hole corresponds to a length of the hook body.

7 . The mask apparatus according to claim 3 , wherein the hook pin is configured to be inserted into the hook groove in a first direction, and
wherein the hook extension portion extends in a second direction intersecting the first direction.

8 . The mask apparatus according to claim 7 , wherein an angle defined between the first direction and the second direction is less than or equal to 90 degrees.

9 . The mask apparatus according to claim 3 , wherein the hook extension portion defines one or more hook through-holes configured to receive the first end or the second end of the strap portion.

10 . The mask apparatus according to claim 9 , wherein each of the pair of ear hook portions further comprises a first band configured to couple the first end of the strap portion to a body portion of the strap portion, the first end of the strap portion passing through the one or more hook through-holes.

11 . The mask apparatus according to claim 10 , wherein each of the pair of ear hook portions further comprises a second band configured to receive the second end of the strap portion.

12 . The mask apparatus according to claim 10 , further comprising a length adjustment portion member configured to adjust a length of the strap portion disposed around an ear of a user, and
wherein the length adjustment portion member includes an opening configured to allow the second end of the strap portion and the body portion of the strap portion to pass therethrough.

13 . The mask apparatus according to claim 12 , wherein the hook extension portion of the first hook portion defines one hook through-hole among the one or more hook through-holes, and
wherein the hook extension portion of the second hook portion defines two hook through-holes among the one or more hook through-holes.

14 . The mask apparatus according to claim 13 , wherein the first band is configured to couple the first end of the strap portion, which passes through the one hook through-hole, to the body portion of the strap portion.

15 . The mask apparatus according to claim 14 , wherein each of the pair of ear hook portions further comprises a second band configured to receive the second end of the strap portion that passes through the two hook through-holes.

16 . The mask apparatus according to claim 1 , further comprising a neck band configured to connect the pair of ear hook portions to each other.

17 . The mask apparatus according to claim 16 , wherein the neck band comprises:
a band body; and a pair of hooking portions that are bent from ends of the band body and extend toward each other.

18 . The mask apparatus according to claim 17 , wherein the neck band further comprises a hook protrusion that protrudes from an end of each of the pair of hooking portions.

19 . The mask apparatus according to claim 1 , wherein the through-hole is configured to communicate air with an inner space defined between the mask body and the mask body cover and to decrease a temperature in the inner space.

20 . The mask apparatus according to claim 19 , wherein each of the first hook portion and the second hook portion is configured to, based on a user wearing the mask apparatus, block at least a portion of the through-hole.
