US 11,135,606 B1 · Fluid applicator assemblies

Abstract

Fluid applicator assemblies which can be attached to or fabricated integrally with a blowing apparatus such as a leaf blower as a source of flowing air to atomize and eject atomized liquids into spaces and/or onto surfaces may include a nozzle having a nozzle body. At least one air flow cavity may be provided in the nozzle body. An air inlet slot may extend through the nozzle body and may be disposed in fluid communication with the at least one air flow cavity. A fluid ejection portion may be carried by the nozzle body. The fluid ejection portion may include an ejection head support extending from the nozzle body. A fluid ejection head may be carried by the ejection head support. A tube opening may extend through the fluid ejection portion. A fluid ejection slot may be provided in the fluid ejection head and disposed in fluid communication with the tube opening. A liquid container may be disposed in fluid communication with the fluid ejection slot through the tube opening. Other embodiments of the fluid applicator assemblies are disclosed.
