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. A portion of the rear body defines an accommodation portion accommodating the air cleaning module. The air cleaning module includes a fan module disposed at a seating portion of the accommodation portion, a filter disposed at a rear side of the fan module and purifying air flowing into the fan module, and a filter housing including a filter frame surrounding a side surface of the filter and a filter cover covering a rear surface of the filter. The inlet is provided at the filter cover.

Mask apparatus with rear surface inlet, outlet and filter assembly

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.

Mask apparatus

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, accommodating a user's face, 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. A portion of the rear body protrudes toward the front body and defines an accommodate portion. The air cleaning module includes: a fan module disposed at the accommodation portion and defining an opening, a flow guide covering the opening, a filter disposed at a rear surface of the flow guide, and a filter housing covering a rear surface of the filter. The flow guide defines a communication hole guiding air passing through the filter to an inside of the fan module.

Mask apparatus with filtered rear fan inlet

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.

An air flow controller for an air cleaner and an air cleaner are provided. The air flow controller may include a fan, and a housing, the fan being provided in the housing and the housing being movable from an initial horizontal position in which the air flow controller directs air flow in a vertical direction to an inclined position in which the air flow controller directs air flow in a diagonal direction.

Air cleaner

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.

An air cleaner is provided that may include a case including a first suction inlet, the case having a cylindrical or cone shape; a fan housing provided inside of the case, the fan housing accommodating a fan therein; a filter provided at a suction side of the fan, the filter filtering foreign materials in air which is suctioned through the first suction inlet; and a housing suction flow path formed between an outer surface of the fan housing and an inner surface of the case, the housing suction flow path allowing air which is suctioned through the first suction inlet to flow toward and through the filter. The housing suction flow path may include a first flow path inlet having a predetermined first width, and a second flow path inlet through which air having passed through the first flow path inlet flows, the second flow path inlet having a second width greater than the first width.

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. The mask body defines a cover coupling groove along an edge of the mask body, and the cover coupling groove is coupled to an edge of the mask body cover.

An air cleaner is provided that may include a main body having at least one cylindrical filter and at least one filter frame that forms a mounting space for the at least one filter; and a cylindrical case coupled to an outside of the main body, the cylindrical case having at least one suction inlet through which air is suctioned toward the at least one filter, so that air may be suctioned in 360-degree directions. If the cylindrical case is opened, the at least one filter may be extracted to the outside in a radial direction from the mounting space, thereby facilitating attachment/detachment of the at least one filter.

According to an embodiment of the present disclosure, a ceiling fan includes a shaft coupled to a ceiling or a wall surface, a housing cover provided at a central axis thereof with a shaft and receiving a motor assembly and an electronic unit, and a blade coupled to the housing cover. The electronic unit is provided in a multi-stage.

Ceiling fan and method for controlling the same

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.

An air cleaner is provided that may include a first air cleaning module having a first fan that generates air flow from a first suction inlet toward a first discharge outlet; a second air cleaning module having a second fan that generates air flow from a second suction inlet toward a second discharge outlet; a dividing plate provided between the first air cleaning module and the second air cleaning module; and a display provided at inside of the dividing plate and in which a light source is provided.

A ceiling fan may include a shaft coupled to a ceiling, a cover to surround the shaft, a main blade having a blade hole which is a space open inward, and a sub-blade positioned in the blade hole. The sub-blade is disposed to have an angle of attack different from an angle of attack of the main blade. The ceiling fan may resolve a red zone of the air flow and may improve air volume and the flow rate due to the dual blades.
