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.

An air purifier according to the present disclosure includes a first blower having a first fan configured to generate an air flow from a first suction part toward a first discharge part, a second blower having a second fan configured to generate an air flow from a second suction part toward a second discharge part, an installation space part configured to be formed between the first blower and the second blower, a power transmitter configured to be positioned inside the installation space part, to be fixed to any one of the first blower and the second blower, and to transmit wireless power, and a power receiver configured to be positioned inside the installation space part, to be fixed to the other one of the first blower and the second blower, and to receive wireless power transmitted from the power transmitter.

Air purifier

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.

An air conditioning apparatus according to an aspect of the present invention includes a main body including a suction part through which air is suctioned and a discharge part through which the air suctioned through the suction part is discharged, a fan disposed in the main body to allow the air to flow, an electric charge device coupled to the main body outside the main body to charge dust in the air, and a filter device disposed between the suction part and the discharge part in the main body to collect the charged dust particles.

Air conditioning apparatus

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 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 mask apparatus includes: a mask body including an air duct disposed at a front surface of the mask body, a fan module disposed at the front surface of the mask body to correspond to a suction hole of the air duct, and configured to suction external air to supply the suctioned air to the air duct, and a mask body cover that is coupled to the front surface of the mask body and that covers the fan module and the air duct. An air passage through which air suctioned by the fan module flows is provided in the air duct, and an embossed portion is disposed on at least a portion of a surface of the air duct that is configured to be in contact with the air flowing through the air passage.

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.

A mask apparatus includes a mask body and a mask body cover coupled to the mask body. The mask body includes a front surface, a rear surface, and a pair of air ducts disposed at left and right sides of the front surface. The mask body is configured to mount a pair of fan modules at suction sides of the pair of air ducts. The mask body cover covers the pair of air ducts and the pair of fan modules.
