The present disclosure relates to a portable air purifier. In the portable air purifier, a fan base is disposed between a fan module including a mixed flow fan and a filter, and forms a passage that connects between the filter and the fan module while coupling the filter and the fan module. Accordingly, the portable air purifier can ensure improvement in air purification performance with no increase in the size of the portable air purifier.

A high elongated portable air-conditioner is disclosed. The air-conditioner comprises a compressor, a condenser, and an evaporator located inside a housing. The air conditioner further comprises a cool air inlet and outlet and a warm air inlet and outlet. The air-conditioner has an axial evaporator fan and a radial condenser fan and the housing of the air-conditioner has an elongated shape where the end sections of the elongated air conditioner housing forms a top section and a bottom section, respectively. Other features of a portable air-conditioner are also disclosed.

Disclosed is an air cleaner, more specifically, an air cleaner including a blower that inhales air from the outside, filters the inhaled air, and discharges the filtered air, a flow adjusting device disposed on the blower to inhale the air discharged from the blower, adjust a discharge direction of the inhaled air, and discharge the air, and a guide member disposed below the flow adjusting device to change a state of the flow adjusting device. The guide member may include a plurality of gears arranged inside the guide member to be rotatable, some of the plurality of gears may be connected to each other to be rotatable in engagement with each other, and the flow adjusting device may change the discharge direction of the air by rotations of the plurality of gears of the guide member.

An air cooler includes a body having a top portion, a bottom portion, and a middle portion situated between the top and bottom portions. The air cooler further includes a fan disposed in the top portion of the body. The fan includes a fan hub and a plurality of fan blades centrally attached to the fan hub. The air cooler also includes a first mister disposed at a first location within the body. The first location is in front of the plurality of fan blades in the top portion of the body. The air cooler further includes a second mister disposed at a second location within the body. The second location is in front of the plurality of fan blades in the top portion of the body and different from the first location.

An air purifying system may include a main air purifier that has a flat upper surface configured to support at least two cylindrical portable air purifiers. Each of the main and portable air purifiers may have a fan to suction air and a filter to filter suctioned air. The upper surface of the main air purifier may include a seating groove, an elastic member provided in the seating groove, and a seating plate resting on top of the elastic member. When a portable air purifier is seated on the seating groove, the elastic member may be compressed and the seating plate may be lowered such that the portable air purifier may be supported within an inner wall of the seating groove. When the portable air purifier is removed from the seating groove, the elastic member may expand and raise the seating plate back to an initial position.

A system and method for creating a microenvironment within an ambient environment is disclosed. The first outlet is configured for expelling a gas at a first velocity sufficient for producing a gas curtain that separates the microenvironment from the ambient environment. The second outlet is configured for expelling the gas at a second velocity within the microenvironment. An inlet is spaced apart from the first outlet and the second outlet and is in fluid communication with a suction unit. The suction unit is positioned downstream of the inlet and configured for removing gas from the microenvironment through the inlet. The first velocity is greater than the second velocity.

Disclosed herein is a humidifier including an improved structure of a water collection tank. The humidifier includes a main body, a water supply tank provided in an upper portion of the main body, a humidifying fabric arranged in an inside of the main body and disposed below the water supply tank to receive water, a fan configured to move air through the humidifying fabric, a water collection tank configured to collect water from the humidifying fabric, a pump configured to pump water from the water collection tank to the water supply tank, and a humidifier lower cover coupleable to and decoupleable from a lower end of the main body. The water collection tank includes a water collection tank top cover provided in an upper portion of the water collection tank, and a water collection tank lower cover configured to be accessible through the lower end of the main body.

A mister-fan apparatus includes: a housing having a fan end and a reservoir end; at the fan end, a fan unit; at the reservoir end, a reservoir; a motor; a pump; an inlet conduit from the reservoir to the pump; and an outlet conduit from the pump to the fan unit, collectively configured for, through the use of the inlet and outlet conduits, pumping fluid from the reservoir to the fan unit so that the fan can output mist; a track peripherally surrounding the housing at least partway around; an attaching device having an attaching end and an extension end; a tongue having a track end, and a connection end connected to the extension end; and, within the track, a retaining slider connected to the track end; wherein the attaching end is configured for removably attaching to an external structure for supporting the apparatus. The track may include a pair of ridges, rigidly connected to the housing, that extend initially outwardly from the housing, and later toward each other but only to an extent of leaving a separation serving as a slot.

Disclosed is an air cleaner, more specifically, an air cleaner including a blower that inhales air from the outside, and filters the inhaled air, and discharges the filtered air, a flow adjusting device disposed on the blower to inhale the air discharged from the blower, adjust a discharge direction of the inhaled air, and discharge the air, and a guide member disposed below the flow adjusting device to change a state of the flow adjusting device. An angle formed between a top surface of the flow adjusting device and a top surface of the blower may increase or decrease based on operations of the plurality of links, so that the state of the flow adjusting device may be changed from an orientation in which the top surface of the flow adjusting device is horizontal with the top surface of the blower to an orientation in which the top surface of the flow adjusting device is perpendicular to the top surface of the blower.
