A mask apparatus includes a mask body, a seal disposed at a rear surface of the mask body, a fan module disposed at a front surface of the mask body, and a mask body cover that covers the fan module and is coupled to the front surface of the mask body. The mask body includes an air duct configured to guide external air from the fan module to a breathing space inside the seal, and an air exhaust hole configured to discharge air exhaled into the breathing space to an outside of the mask body. An area of a duct outlet of the air duct is greater than an area of a duct inlet of the air duct.

A mask apparatus includes a mask body, a fan module configured to be disposed at a front surface of the mask body, a mask body cover that is coupled to the mask body and configured to cover the fan module and that includes a filter mounting portion, a seal that is disposed at a rear surface of the mask body and defines a breathing space therein, a filter configured to be disposed at the filter mounting portion, and a filter cover coupled to the filter mounting portion and configured to cover the filter from an outside of the mask body cover. The filter cover includes a front surface portion, and a side surface portion that is disposed rearward relative to the front surface portion and extends along an edge of the front surface portion, the side surface portion defining an air inlet.

A blower includes a first extension having a first discharge port formed in a first wall, a second extension having a second discharge port formed in a second wall facing and spaced apart from the first wall, a fan provided below the first and second extensions to guide air toward each of the first tower and the second tower, a first gate provided inside the first tower or protruding from the first wall, a second gate provided inside the second tower or protruding from the second wall, a first guide motor to change a position of the first gate, and a second guide motor to change a position of the second gate.

A blower may include a body or case having a suction hole through which air passes, a fan provided inside the body and causing a flow of air, and a filter provided inside the body. The filter may be positioned upstream of the fan and extend in a longitudinal direction of the body. A longitudinal axis of the filter may be shifted or displaced with respect to a longitudinal axis of the body.

A mask apparatus includes a mask body including an air duct and a fan module mounting portion disposed at a suction-side of the air duct, a fan module disposed at the fan module mounting portion, and a mask body cover that is coupled to the front surface of the mask body and covers the fan module and the air duct. The mask body cover defines an air suction hole configured to communicate air with a fan inlet, and the fan module has a first end inserted into the air duct and a second end coupled to the mask body. The fan module mounting portion includes a fan module coupling portion that protrudes from the front surface of the mask body and that couples the second end of the fan module to the mask body.

A mask apparatus includes a mask body configured to receive a battery at a center region of a front surface of the mask body, a plurality of electronic components that are disposed at the mask body and that include a pair of fan modules configured to be disposed at left and right sides of the battery, respectively, and a control module configured to be disposed between the battery and at least one of the pair of fan modules, and a mask body cover that is coupled to the mask body and covers the plurality of electronic components. The center region configured to receive the battery, the pair of fan modules, and the control module are arranged along a widthwise direction of the mask body.

A mask apparatus includes a mask body including an air duct disposed at a front surface of the mask body, and a fan module mounting portion disposed at a suction-side of the air duct, a fan module disposed at the fan module mounting portion and configured to supply external air to the air duct, a mask body cover that is coupled to the front surface of the mask body and covers the fan module and the air duct, a seal coupled to a rear surface of the mask body and configured to contact a user's face and define a breathing space for the user, a sealing bracket that fixes a portion of the seal to the rear surface of the mask body, and a pad configured to be disposed inside the breathing space.

A mask apparatus includes a mask body including a body front surface and a body rear surface configured to cover at least a portion of a user's face, a fan module disposed at the body front surface, a mask body cover that is coupled to the mask body and defines an inner space accommodating the fan module, a seal coupled to the body rear surface and configured to define a breathing space between the mask body and the user's face. The mask body defines an opening that passes through the mask body and that connects the inner space of the mask body cover to the breathing space. A pressure sensor is disposed in the opening and configured to sense air pressure in the breathing space.

Mask apparatus and method for controlling the same

A blower is provided that includes a lower case having a suction hole through which air flows into the blower; an upper case which is disposed at an upper side of the lower case and which has a discharge port through which the air is discharged from the blower; a fan motor that provides a rotational force; and a fan disposed inside of the lower case and fixed to a motor shaft of the fan motor.
