This disclosure relates to nozzles, in particular bath and shower wands that may be hand held and which generate microbubbles from water saturated with air. The bath and shower wands comprise an elongate body comprising an inlet, an elongate outlet and internal flow constriction that can generate micro bubbles from water passing through the wand.

An air treatment system is provided which includes an appliance and a replaceable cartridge installable therein. The replaceable cartridge contains a liquid compound to be aerosolized and has a cartridge outlet through which the aerosolized compound is discharged during operation. A pump is provided to supply air to the replaceable cartridge to generate the aerosolized compound from the liquid compound contained in the replaceable cartridge, and a controller is provided for controlling the pump to supply the air to the replaceable cartridge to generate and discharge the aerosolized compound from the appliance. The appliance may further include a lift mechanism to assist in receiving the cartridge and moving the cartridge from a loading position to an operational position. The appliance may also communicate with a smartphone or other external device to provide additional functionality.

The present technology presents an apparatus for cleaning the air and surfaces within an enclosed space of a viral, microbial, or malodor contamination. In an exemplary embodiment, the apparatus includes: a container configured to contain a water and a solid or gel pack that releases the gaseous cleaning agent upon contact with the water; an aerator housed in the base of the container; an air distributor in the container configured to distribute air from the aerator into the container to cause agitation of the water and release of gaseous agent; and a lid on the container having an opening configured to accelerate an air-borne spray of gaseous agent and water droplets therethrough into the surroundings.

A system and method is provided for demand-based control of a cold water spray system of an exhaust ventilation system. Embodiments include determining a demand load of a cooking appliance that generates cooking effluent in a vicinity of an exhaust hood, and determining a temperature of water in the cold water spray system. The cold water spray system is controlled in response to at least one of the determined appliance demand load and the determined temperature of water in the cold water spray system to maintain a low temperature of water in the cold water spray system below a predetermined temperature threshold, thereby enabling efficient removal of contaminants from the exhaust hood by the cold water spray system.

The appliance may also communicate with a smartphone or other external device to provide additional functionality.

A removable cartridge for use with a liquid diffusion device is provided. The removable cartridge includes a cartridge housing defining an internal housing cavity, partially filled with a liquid to be diffused, and a diffusion head positioned within the internal housing cavity with a venturi device for generating diffused liquid from the liquid contained in the internal housing cavity. The diffusion head defines at least a portion of a gas supply conduit that extends from a bottom end of the removable cartridge to the venturi device through the liquid to be diffused to enable the venturi device to be supplied with pressurized gas from an external source via the bottom end of the removable cartridge.
