Provided is a rotator structure of a nanomist-generating device which generates a nanomist by rotating a rotator having a conical shape, wherein a lower portion of the rotator is immersed in water and mist-scattering ports are disposed in an upper portion; the device generates a nanomist by scattering the water through the ports, the water being drawn up along an inner wall surface of the rotator by rotating the rotator; and a radius at an upper end of the ports is an upper portion radius R1, a height to the upper end of the ports from a waterline L is a drawing height H, and a mean angle between a horizontal line and the inner wall surface is a side surface mean angle 1; and the angle 1 is set within 5% of for satisfying a basic structure equation R1 sin.sup.3 +2 H cos sin.sup.2 +H cos.sup.3 =0.

Provided is an air conditioner. The air conditioner includes a water tank to store water, a visual body disposed over the water tank and formed of a transparent material, a watering housing to draw water stored in the water tank and to spray the drawn water to the visual body, a water level sensor to measure a water level of the water tank in a multi-stage, a top cover assembly disposed over the visual body and having a water supply hole to supply water to the water tank, and a water level display unit disposed beside the water supply hole of the top cover assembly to display a water level measured by the water level sensor in a multi-stage.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a water tank storing water; a watering housing disposed in the water tank and suctioning water stored in the water tank to spray suctioned water to the outside; a watering motor providing a torque to the watering housing; a pump groove protruding inside the watering housing, suctioning water of the water tank into the watering housing when rotating, and pumping the suctioned water to an upper side of the watering housing; and a nozzle disposed in the watering housing and spraying the upwardly pumped water to the outside of the watering housing.

A water dispersing system (WDS) that allows a selectable quantity of water to be dispersed into an environment. The WDS utilizes a fan and a water supply assembly. The fan has a frame inside of which are two rotating blades, and preferably a stand. The water supply assembly includes a reservoir, a water tube, and a water dispersing head. Water is gravity fed from the reservoir, through the water tube and out of the head. Water from the head is directed into the first fan's rotating blades. Once the water hits the blades, the water is re-directed back out through a front grill on the fan. The second fan blades project air outward. The amount of water that comes from the WDS can be selectably chosen, from a light mist to a heavier spray, and the temperature of the water can be lowered by placing ice into the reservoir with the water. An excess water basin catches any water that drips downward from the blades.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a base body including an upper body and a lower body coupled to a lower part of the upper body, a water tank disposed at an upper part of the upper body, storing water, and including a water housing spraying water to the inside, a watering motor installed at the upper body and providing a torque to the watering housing; and a blower motor installed at the lower body. Here, the lower body, the upper body, and the water tank are stacked sequentially. The blower motor, and the watering motor are disposed vertically inside the base body. The watering motor, and the blower motor are spaced a predetermined interval away from each other and disposed on the same axis.

A personal cooling device utilizes a portable container for retaining a liquid that is wicked into a wicking, material and a fan to draw air into the container through a plurality of apertures to produce a flow of cool air. Air drawn into the container through the apertures flows through the wicking material and is cooled by evaporative cooling. The air then flows out of the top of the container and through the air moving device. A funnel is configured around the outer perimeter of the container to capture any liquid that spills out of the apertures and direct it back into the container. A battery pack may be coupled to the air moving device by an extension cable for storing the battery pack in a more convenient location, such as on a belt.

A pump-fan assembly of an air modification device may include a fan, a pump and a disk. The fan may include a central hub disposed on a top surface of the disk, and a plurality of blades extending from the hub towards an outer circumferential edge of the disk. The pump may include a hollow pump body defining an inner tubular passage between an inlet end and a discharge end. An impeller may be arranged at the inlet end and an outlet port may be arranged at the discharge end. The pump and the fan may be coupled at an interface between the discharge end of the pump body and a bottom surface of the disk. The outlet port may be disposed in the interface and arranged to guide a stream of pumped liquid along the bottom surface of the disk. The disk may define a liquid barrier.
