Abstract

A mask apparatus includes: a mask body including a rear body and a front body coupled to a front surface of the rear body and providing an inlet and an outlet, a face guard coupled to the rear body and defining a respiration space, and an air cleaning module purifying air introduced into the inlet and supplying the purified air to the respiration space. Each of left and right edges of the rear body provides a strap connection portion into which a strap is coupled. The strap connection portion includes: a strap recess provided at a rear surface of the rear body, a strap hole defined in the strap recess, a strap bar connecting upper and lower surfaces of the strap recess and spaced apart from the strap hole, and a waterproof sleeve extending from the front surface of the rear body along an edge of the strap hole.

First claim

What is claimed is:

1 . A mask apparatus comprising:
a mask body having an inlet and an outlet and including a rear body and a front body, the front body being coupled to a front surface of the rear body; a face guard that is coupled to a rear surface of the rear body, that is configured to accommodate a portion of user's face, and that defines a respiration space at an inner side thereof; and an air cleaning module that is mounted on the rear body, that is configured to purify air introduced into the inlet, and that is configured supply the purified air to the respiration space, wherein a portion of the rear body protrudes toward the front body and defines an accommodation portion configured to accommodate the air cleaning module, wherein the inlet and the outlet are respectively provided in the rear surface of the mask body to thereby (i) introduce air into the mask body through the rear surface of the mask body and (ii) supply the introduced air to the respiration space through the rear surface of the mask body, wherein each of a left edge and a right edge of the rear body provides a strap connection portion into which a strap is coupled, and wherein the strap connection portion includes:
a strap recess provided at the rear surface of the rear body,
a strap hole defined in the strap recess,
a strap bar that connects an upper surface of the strap recess to a lower surface of the strap recess and that is spaced apart from the strap hole, and
a waterproof sleeve extending from the front surface of the rear body along an edge of the strap hole.

2 . The mask apparatus of claim 1 , wherein an end portion of the waterproof sleeve is in contact with a rear surface of the front body.

3 . The mask apparatus of claim 2 , wherein the accommodation portion includes:
a fastening surface extending forward from a side end portion of the rear body, a seating surface that extends from an end portion of the fastening surface in a central direction of the rear body and that is configured to accommodate the air cleaning module, an air guide surface connecting an end portion of the seating surface to the front surface of the rear body, an upper surface connecting upper ends of the fastening surface, the seating surface, and the air guide surface to the front surface of the rear body, and a lower surface connecting lower ends of the fastening surface, the seating surface, and the air guide surface to the front surface of the rear body, and wherein a first surface of the waterproof sleeve extends along the upper surface or the lower surface of the accommodation portion.

4 . The mask apparatus of claim 3 , wherein the first surface of the waterproof sleeve is (i) integrated with the upper surface or the lower surface of the accommodation portion or (ii) defined by the upper surface or the lower surface of the accommodation portion.

5 . The mask apparatus of claim 4 , wherein the accommodation portion includes:
a left accommodation portion provided at a left side from a center of the rear body, and a right accommodation portion provided at a right side from the center of the rear body, and wherein the air cleaning module is mounted on each of the left accommodation portion and the right accommodation portion.

6 . The mask apparatus of claim 3 , wherein the air cleaning module includes:
a fan module that is disposed at the seating surface and that is configured to move air through a rear surface thereof, and a filter that is disposed at the rear surface of the fan module and that is configured to purify air supplied to the fan module, and wherein the fan module is a centrifugal fan configured to intake air in an axial direction and discharge air in a radial direction.

7 . The mask apparatus of claim 6 , wherein the air cleaning module further includes:
a flow guide that is disposed between the filter and the fan module and that defines a space configured to accommodate the filter at a rear surface thereof, and a filter housing that is mounted on the rear body and that covers the filter.

8 . The mask apparatus of claim 7 , wherein:
a rear surface of the fan module defines an opening, the flow guide shields the opening at the rear surface of the fan module, and the flow guide defines a communication hole configured to guide air passing through the filter to the fan module.

9 . A mask apparatus comprising:
a mask body having an inlet and an outlet and including a rear body and a front body, the front body being coupled to a front surface of the rear body; a face guard that is coupled to a rear surface of the rear body, that is configured to accommodate a portion of user's face, and that defines a respiration space at an inner side thereof; and an air cleaning module that is mounted on the rear body, that is configured to purify air introduced into the inlet, and that is configured supply the purified air to the respiration space, wherein a portion of the rear body protrudes toward the front body and defines an accommodation portion configured to accommodate the air cleaning module, wherein the inlet and the outlet are respectively provided in the rear surface of the mask body to thereby (i) introduce air into the mask body through the rear surface of the mask body and (ii) supply the introduced air to the respiration space through the rear surface of the mask body, wherein the outlet is spaced apart from the inlet toward a center of the rear body by a predetermined distance, wherein each of a left edge and a right edge of the rear body provides a strap connection portion into which a strap is coupled, and wherein the strap connection portion includes:
a strap recess provided at the rear surface of the rear body,
a strap hole defined in the strap recess,
a strap bar that connects an upper surface of the strap recess to a lower surface of the strap recess and that is spaced apart from the strap hole, and
a waterproof sleeve extending from the front surface of the rear body along an edge of the strap hole.

10 . The mask apparatus of claim 9 , wherein an end portion of the waterproof sleeve is in contact with a rear surface of the front body.

11 . The mask apparatus of claim 10 , wherein the accommodation portion includes:
a fastening surface extending forward from a side end portion of the rear body, a seating surface that extends from an end portion of the fastening surface in a central direction of the rear body and that is configured to accommodate the air cleaning module, an air guide surface connecting an end portion of the seating surface to the front surface of the rear body, an upper surface connecting upper ends of the fastening surface, the seating surface, and the air guide surface to the front surface of the rear body, and a lower surface connecting lower ends of the fastening surface, the seating surface, and the air guide surface to the front surface of the rear body, and wherein a first surface of the waterproof sleeve extends along the upper surface or the lower surface of the accommodation portion.

12 . The mask apparatus of claim 11 , wherein the first surface of the waterproof sleeve is (i) integrated with the upper surface or the lower surface of the accommodation portion or (ii) defined by the upper surface or the lower surface of the accommodation portion.

13 . The mask apparatus of claim 12 , wherein the accommodation portion includes:
