The present invention relates to systems and methods for producing mist and/or for otherwise providing a fluid to a desired location. More particularly, some implementations relate to a system that is configured to use a portable pumping system to spray a mist of water in a desired location. In some implementations, the pumping system includes one or more fluid containers, pressurizers, nozzles, and/or control mechanisms. In some cases, the system is configured to spray mist for a set period of time, to spray pulses of mist, to regulate mist flow based on ambient temperature and/or humidity, and/or to otherwise control or optimize mist flow. Other implementations are also described.

The personal cooling misting system disclosed provides for a wearable fluid reservoir to contain a volume of misting fluid, and an electrically operated pump proximate to the reservoir to pump the misting fluid from the reservoir to a misting head. The misting head facilitates atomizing the misting fluid. The system further provides for feed tubing to direct the misting fluid from the reservoir to the pump, and distributive tubing to direct the misting fluid from the pump to the misting head. The system also includes a pump control to control at least one of a pressure and a flow rate of the misting fluid through at least one of the feed tubing and distributive tubing, and the system includes a programmable circuit board to facilitate system control via the pump control, as well as directing to the pump control a misting distribution pattern for at least one of a consistent or intermittent misting pattern.

An umbrella with environmental control systems uses an environmental control system, an electrical control system (ECS), and a fluid delivery system to modify the local environment beneath the umbrella's canopy. The environmental control system has multiple spray nozzles, multiple fans, and multiple heating elements. The spray nozzles mist water onto the user, the fans blow air onto the user, and the heating elements heat up the air beneath the umbrella's canopy. To accomplish this, all of the components of the environmental control system are arranged advantageously beneath the umbrella's canopy. The umbrella has a handle, a support rod, multiple rib members, and a canopy. The support rod acts as a rigid connection channel through which the hoses that connect the spray nozzles to the fluid delivery system run. The ECS is the system that enables the user to selectively activate the various electrical components of the environmental control system.

A cleaning device is provided that includes a cleaning element, a cleaning head, a housing, an electric pump, a battery, a container of cleaning fluid, an activation button, and a spray nozzle. The cleaning element and the cleaning head have spray openings that are in registration with one another. The container forms a fluid and air tight connection with the pump. The activation button places the pump and the battery in electrical communication. The spray nozzle forms a fluid tight and air tight connection with the pump so that the pump is configured to spray fluid from the container through the first and second spray openings onto a surface to be cleaned. The cleaning head, the cleaning element, and the spray nozzle define a cavity that traps spray from the spray nozzle between the cleaning device and the surface to be cleaned.

A method and apparatus for depositing a fluid over an interface. A nozzle may comprise a body having a first end and a second end, an input located at the first end of the body, an output located at the second end of the body, and a plurality of channels located within the body. The input may be configured to receive a fluid. The plurality of channels may have a configuration that causes the fluid received through the input to flow through the plurality of channels and exit the output to form a deposition having a desired shape over an interface.

Sprayer devices and related methods. The sprayer devices can be of a type that may be carried or worn on the back of a user. Each sprayer device has a tank, a spray outlet (e.g., a spray nozzle or spray wand) and either a manual or power pump. The sprayers may also incorporate one or more of the following: a) a brace member for deterring bending or deformation of a bottom bracket on the sprayer, b) a pump axle with redundant rotation-limiting stop members useable for either right-handed or left-handed operation, c) system for selective and/or controlled agitation or non-agitation of liquid within the sprayer tank and/or d) an information card holding niche with removable information card.

A tank holding a quantity of liquid releasably connects to an electric pump module through a connector to provide a portable sprayer. The tank connects to a feed line that supplies spray nozzle with the liquid. The connector combines a quick disconnect connector with a pressure relief valve. The electric pump module includes an electric pump, a switch assembly, and a check valve. The electric pump module directs gas through the check valve into the connector to increase the gas pressure in the tank and force the liquid in the tank to flow through the feed line and out the spray nozzle. The switch assembly turns off the electric pump when the gas pressure in the tank exceeds a predetermined limit while maintaining the flow of liquid through the spray nozzle.

An authentication reader and a dispenser comprising the authentication reader for authenticating a product having a taggant ink disposed on the product's surface.

A cleaning device is provided that includes a cleaning element, a cleaning head, a housing, an electric pump, a battery, a container of cleaning fluid, an activation button, and a spray nozzle. The cleaning element and the cleaning head have spray openings that are in registration with one another. The container forms a fluid and air tight connection with the pump. The activation button places the pump and the battery in electrical communication. The spray nozzle forms a fluid tight and air tight connection with the pump so that the pump is configured to spray fluid from the container through the first and second spray openings onto a surface to be cleaned. The cleaning head, the cleaning element, and the spray nozzle define a cavity that traps spray from the spray nozzle between the cleaning device and the surface to be cleaned.

A wearable fluid-dispensing apparatus that includes a flexible wristband coupled to and surrounding a wrist-arm area of a user, with the wristband having a frame disposed along an outer surface of the wearable wristband and at a ventral side of the user's wrist, an enclosed cartridge coupled to the frame for housing a fluid therein, and a fluid transfer conduit disposed within the enclosed cartridge for transporting the fluid from the enclosed cartridge to a nozzle port on a finger-activatable pump assembly coupled to the frame. The pump assembly defines a nozzle port disposed above a top end of the wristband and angled toward the user's palm, defining a fluid extraction passageway fluidly coupled to the nozzle port and the fluid transfer conduit, and operably configured to translate downwardly toward the fluid extraction passageway fluidly to generate a vacuum therein and emit the fluid on the user's inner hand.
