Abstract: An apparatus for adapting a blower system to the dispersing of liquid material is partially housed within an extension tube of a portable blower and includes a pressurizing tub with an inlet for accepting airflow discharged by the blower. The pressurizing tube discharges into a liquid container thus increasing pressure within the container. An extraction tube exits the container and meets a Venturi tube that also accepts airflow discharge by the blower. A vacuum is created in the extraction tube through first and second apertures that allow fluid communication between the Venturi tube and the extraction tube. The vacuum created in the extraction tube extracts liquid from the liquid container and the liquid is drawn out of the extraction tube through the Venturi hole into the Venturi tube mixing with air flowing there through and discharging into airflow by-passing the spray adapter apparatus.

Abstract: An entraining device in the nature of a paint gun receives pressurized air, which entrains a hair treatment formulation into the stream of pressurized air.

The hair treatment formulation may be supplied by a storage chamber which is part of or connected to the entraining device. The system could also be used for applying various treatments to the skin or to other mammals.

Abstract: The invention includes a spraying device (10) for producing a precise degree of liquid droplet generation on a repeatable basis by combining a specified rate of regulated flow of liquid material with a regulated flow of high-pressure air. The spraying device (10) includes an electric or engine driven direct drive compressor (12.) Coupled to the compressor (12) is an air storage tank (14) providing air pulsation reduction to the regulated air and serves as a reservoir for excess airflow generation. A Venturi nozzle (18) is connected to the compressor (12.) A liquid supply tube (24) uses a fixed or variable restriction to regulate the liquid flow to the nozzle (18.) The vacuum in the liquid supply line (24) draws this liquid flow and mixes the liquid externally with the regulated air in exacting proportions forming specified liquid droplet sizes. The device (10) uses air and liquid regulation combined with a Venturi nozzle (18) and is able to generate extremely consistent liquid droplet sizes.

Abstract: Embodiments of the present invention are directed to a fluid dispenser for dispensing landscape maintenance fluids or the like which contain products such as fertilizers, herbicides, and pesticides. The fluid dispenser injects the fluids directly into the mainstream of an irrigation system. The dispensing system operates by shunting a portion of the main irrigation water stream through a bypass to the dispenser containing the product to be dispensed. The water dilutes the product to be applied, and is injected back into the main irrigation stream by the back pressure of the irrigation system. When the irrigation is completed, the fluid flow in the main irrigation stream is reduced or terminated and the pressure drops. After the pressure drops, the fluid ceases to be diverted to the container, and the main irrigation stream drains.
