A spraying apparatus, used for connecting a high-pressure liquid supply device to receive a high-pressure liquid conveyed by the high-pressure liquid supply device, includes a container, a delivery pipe, a liquid-mixing fitting, a pressurized fitting and a foam-generating element. The container, used for accommodating a detergent. The liquid-mixing fitting is connected with the high-pressure liquid supply device. When the high-pressure liquid flows by, the detergent is inhaled to the liquid-mixing fitting via the delivery pipe to mix the high-pressure liquid for forming a detergent mixture. An inner wall of the pressurized fitting is furnished with at least one helical groove for pressurizing the detergent mixture to form a pressurized detergent mixture. As the pressurized detergent mixture flows by the foam-generating element, a plurality of cleaning foams are formed for enhance cleaning effect.

A bottle includes a squeezable main chamber configured to dispense a bulk liquid; a cap that dispenses the bulk liquid; and a bulkhead between the main chamber and cap, wherein the bulkhead supports a cartridge containing an additive liquid that is dosed into the bulk liquid.

A hose end spray head apparatus includes a spread head body and a hose coupling. The spray head body includes a mixing body and a spray outlet arm formed as a unitary construction. The spray outlet arm extends outwardly from the mixing body and includes a spray bore to discharge a mixed fluid. The spray bore communicates with atmosphere via a first radial sidewall bore and a first offset top surface bore. An axial bottom surface bore extends from the bottom surface to the spray bore and is draws product from a container so as to inject the product into the spray bore. A second radial sidewall bore is configured to communicate an open interior of the container with atmosphere. The hose coupling is secured to the mixing body and mounts to a fluid supply to form the mixed fluid which is discharged through the spray bore.

A stationary fertilizer sprayer assembly for watering or fertilizing a selected area includes a container that is comprised of a fluid impermeable material to contain a fluid fertilizer. A base is coupled to the container and the base rests on a support surface adjacent to an area to be fertilized. A dispensing nozzle is removably coupled to the container such that the dispensing nozzle is in fluid communication with the container and the dispensing nozzle is fluidly attachable to a water source to receive water. The dispensing nozzle includes a mixture valve that is positionable in a mixing position of a non-mixing position. In this way the dispensing nozzle can spray either pure water or a mixture of the fluid fertilizer and water.

A bottle includes a squeezable main chamber configured to dispense a bulk liquid; a cap that dispenses the bulk liquid; and a bulkhead between the main chamber and cap, wherein the bulkhead supports a cartridge containing an additive liquid that is dosed into the bulk liquid.

A trigger sprayer is described which utilizes a ball valve to control the flow of a carrier fluid such as water. The ball valve is actuated by a trigger which is biases to the open position by a torsion spring. Provision is made for the trigger sprayer to draw a chemical solution from a supply container and meter it through one or more outlet devices for providing streams in the form of fan or mist sprays, or other shaped sprays.

A portable chemical dispenser for dispensing a chemical with a diluent includes a valve housing having a valve with an opened position and a closed position, an eductor housing coupled to the valve housing and including one or more eductors, and a nozzle coupled to the eductor housing and configured to direct the flow of a chemical solution to a receptacle, wherein the joint between the valve housing and the eductor housing permits relative rotations between the two housings. The portable chemical dispenser may also be devoid of metering elements that control the dosing of the chemical. A method of using the portable chemical dispenser is also disclosed.

The sprayer includes a sprayer housing defining a chamber, and a cylinder within the chamber. The cylinder defines more than one discharge tube positioned in a longitudinal direction within the sprayer housing, the cylinder being selectively rotatable within the chamber. More than one suction tube extends from a lower portion of the sprayer housing. The more than one suction tube is in selective fluid communication with the more than one discharge tube of the cylinder, as the cylinder is rotated within the chamber. The foam sprayer attachment includes a major body defining a discharge channel and a screen traversing the discharge channel. The major body includes a base with a connecting structure that is a raised lip or a cut-out area that conforms the base to a raised ridge on a discharge connection of the sprayer. The connecting structure includes a pair of non-raised lips bracketing each connecting structure.

The invention relates to a hose end sprayer configured for connecting to a hose and at least one container. The hose end sprayer includes a main housing sub-assembly having a main housing bore, a flow tube assembly and a nozzle. The flow tube assembly is disposed within the main housing bore and slideably displaceable relative thereto between a first position allowing delivery of neither of the first substance and the second substance through the main bore outlet, and a second position allowing delivery of a mixture of the first and second substances through the main bore outlet. The nozzle includes an interference member configured to selectively interfere with the downstream end of the flow tube assembly when the flow tube assembly is in the second position.

A fluid dispensing spraying assembly for adding a fluid to a stream of water includes a conduit that is fluidically coupled to a water supply line. A spray head that is coupled to the conduit is in fluidic communication with the water supply line. A valve, which is Venturi type, is positioned inline with the conduit. A set of tubes that is operationally coupled to the valve is in fluidic communication with the valve. The valve is configured to generate a pressure in the set of tubes that is lower than a pressure in the conduit. Each of a set of reservoirs is selectively fluidically couplable to the valve via a respective tube so that a fluid that is positioned in the reservoir is drawn into the valve and sprayed through the spray head.
