There is disclosed a misting apparatus (10) for producing a mist from a pressurized liquid, comprising: a fan shaft (134) having a rotational axis (104); a rotary jet assembly (130) configured to drive the fan shaft (134) and comprising a radially extending arm (136) configured to convey the pressurized liquid to a jet nozzle (138), wherein the jet nozzle (138) is configured to eject the pressurized liquid in a jet to generate a jet reaction force having a tangential component; a fan 140 coupled to the fan shaft (134) for driving an airflow; and a spray nozzle (152) configured to eject the pressurized liquid into the airflow to produce a mist.

A chemical discharging fan system has a ducted fan adapted and configured to generate a flow of air from an inlet of the fan into a duct of the fan and through the outlet of the fan. A spray gun is arranged on the fan in the flow of the air generated by the fan. The spray gun has a fluid inlet adapted and configured to receive a pressurized fluid from a fluid supply source. The spray gun is configured to intermittently discharge the fluid from the fluid source into the flow of air generated by the fan. A control is in communication with the spray gun. The control is configured to generate a pulse width modulated signal to cycle the spray gun, which causes the fluid to vaporize upon being discharged from the spray gun into the flow of air generated by the fan.

A boom for a sprayer vehicle includes a fluid-carrying medium; at least one nozzle fluidly coupled to the fluid-carrying medium; and at least one unmanned aerial vehicle tethered to the fluid-carrying medium. The at least one unmanned aerial vehicle includes a plurality of fans, and the nozzle is arranged to discharge material through a fan. Related methods and sprayer vehicles are also disclosed.

A personal and portable misting device having at least a pump unit operatively coupled to an inlet tube and an outlet tube with a misting nozzle attached to the outlet tube is described. The inlet tube includes a distal end that is to be coupled to a water source. The distal end has a plug attached to it that is designed to be received in the end of a drain spout of a hard-sided cooler to utilize the melted ice-water typically contained in the cooler as the water source.

Spray nozzle systems and methods of use are described herein. The spray nozzle system may include a stationary tube, a rigid rotor, and a sub-medium supply source. The stationary tube may be in fluid communication with a pressurized air source. The substantially rigid rotor is in fluid communication with the pressurized air source. The substantially rigid rotor includes a substantially rigid conduit that is in fluid communication with the passages of the stationary tube and the rotor. A portion of the conduit is substantially arched such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis. Pressurized air ejected from the outlet produces directional components of the pressurized air in the direction of rotation about the rotor axis; and during use, the pressurized air rotates the rotor and sucks sub-medium from the sub-medium supply source into the stationary tube passage.

Provided is a fragrance discharge device. The fragrance discharge device includes a storage configured to store a fragrance material; a body to which the storage is mounted; a discharge portion configured to discharge, to an outside of the body, at least a portion of the fragrance material supplied from the storage; and a controller configured to control the discharge portion to discharge the fragrance material based on context information including at least one of user information and environmental information around the body.

Provided is a mobile fragrance discharge device. The mobile fragrance discharge device includes a body configured to be movable; a storage mounted to the body and configured to store a fragrance material; a discharge portion configured to connect to the storage and to discharge, to an outside of the body, at least a portion of the fragrance material supplied from the storage; a location detector configured to detect a location or a travel route of the body; and a controller configured to determine a discharge characteristic of the fragrance material based on location information or travel route information of the body and to control the discharge portion to discharge the fragrance material based on the determined discharge characteristic.

Provided is a fragrance discharge device and control method thereof, the fragrance discharge device including a body configured to be wearable by a user; a storage provided to the body and configured to store a fragrance material; a discharge portion configured to discharge, to an outside of the body, the fragrance material supplied from the storage; and a controller configured to control the discharge portion to selectively discharge the fragrance material based on a result of detecting a motion of the user.

An air cleaning apparatus with a moist filter is disclosed. More particularly, the present invention relates to an air cleaning apparatus with a moist filter, being operated such that: water stored in a bottom reservoir tank flows upward in a centrifugal manner; water molecules are finely cleaved in a microfine state and injected through multiple injection holes in the same centrifugal manner to become moist; under such conditions, water flowing into a rotational column, to which a centrifugal force is applied, is filtered while circulating a cycle wherein external air inflowing through air input holes formed below a moist layer is adhered to water molecules in the moist layer and drops down, thereby enabling ultrafine dust as well as fine dust to be filtered with high efficiency and excellent economic advantage.

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.
