Abstract: A handheld extraction cleaner system includes a wet cleaning head including a wet suction nozzle, a dry cleaning head including a dry suction nozzle. A handheld base includes a modular receiver configured to interchangeably couple to the wet cleaning head and the dry cleaning head. A suction source is configured to generate a suction air stream through the wet suction nozzle when the wet cleaning head is coupled to the modular receiver and through the dry suction nozzle when the dry cleaning head is coupled to the modular receiver. A fluid delivery system includes a fluid distributor configured to dispense a cleaning solution on a surface to be cleaned, where at least one of the handheld base and the dry cleaning head is configured to at least partially prevent the fluid delivery system from dispensing the cleaning solution when the dry cleaning head is coupled to the modular receiver.

Abstract: An accessory tool usable with an extraction cleaner having fluid delivery and recovery systems includes a conduit body, spray nozzle, and first and second valves. The conduit body contains a fluid delivery pathway and an airflow pathway. The fluid delivery pathway connects to the fluid delivery system at a hose end of a wand. The airflow pathway connects to the fluid recovery system at the same hose end. The spray nozzle is in fluid communication with the fluid delivery pathway. The second valve is operable for selectively directing a liquid stream, i.e., cleaning fluid provided by the extraction cleaner, to the spray nozzle when the hose end is attached to the extraction cleaner via an accessory hose. The first valve is operable for selectively diverting the liquid stream into the airflow pathway to clean the hose.

Abstract: A media basket assembly for use with an air purifier, such as but not necessarily limited to media basket assembly suitable for use with a vertical airflow type of air purifier. The media basket assembly may include a filter media configured to filter the airflow and a basket for positioning the filter media relative to a lower fan shroud of the air purifier.

Abstract: A game control system is adapted for tracking game statistics such as balls, strikes, and outs, and for operably controlling a scoreboard for displaying this information, and a pitch clock. The system has a device housing that is sized and shaped to be readily hand-held, and which includes an input device for entering game statistics. The device housing contains a transceiver device operably connected with a power source, the transceiver device enabling communication with the scoreboard and the pitch clock. The device housing further includes a pitch clock display that displays the time remaining on the pitch clock, and a pitch clock reset button which enables a reset of the pitch clock display, and also the pitch clock, during the course of the game.

Abstract: An air purifier includes an interior volume divided into upper and lower chambers, with a motorized fan assembly being positioned within the upper chamber. An ultraviolet (UV) light source is positioned within the lower chamber. A lower fan shroud includes concentric annular ribs that extend axially into the lower chamber and terminate in respective flared distal ends. The flared distal ends deflect light from the UV light source to reduce leakage of the light into the upper chamber. A diffuser can surrounds the UV light source, is affixed to the fan shroud, and has angled louvers deflecting the light to further reduce leakage thereof. Embodiments include a cylindrical media basket surrounding the diffuser can and having a media material disposed therein or thereon. The louvers are oriented to direct the light from the UV light source toward the media material.
