Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An air cleaner is provided. The air cleaner may include at least one air cleaning module including a fan, a filter and an inlet through which air is suctioned into the filter; an air flow controller configured to be movably disposed on the at least one air cleaning module and including an air flow control fan to control a flow of the air discharged from the at least one air cleaning module. The air flow controller may be movable from a first position at which the air is discharged in an upward direction to a second position at which the air is discharged in a diagonally upward direction.
