The element comprises: a hollow body (19); a delivery nozzle (32) for delivering a first liquid carried by the hollow body (19); a dispensing nozzle (50) for dispensing a second liquid carried by the hollow body (19); The dispensing nozzle (50) is suitable for producing droplets having a diameter less than 1 mm, particularly comprised between 1 m and 1000 m and the delivery nozzle (32) is suitable for producing droplets having a diameter greater than 1 mm, and particularly comprised between 1 mm and 5 mm.

A dual mode spray gun has a mixing valve with two inlets and two outlets. A handle assembly extending proximally from the valve couples the first inlet to pressurized water and provides means for manually starting and stopping flow. The second inlet draws detergent from a reservoir mounted to the valve. A barrel extending distally from the valve terminates at spray and foam ports connected respectively to the first and second outlets via first and second channels formed through the barrel, the second channel defining an aeration port upstream of the foam port. A mode switch on the mixing valve in a first position allows flow from the first inlet to the spray port, stops flow from the second inlet and stops flow to the foam port, and in a second position stops flow to the spray port and allows flow from the first and second inlets to mix and aerate en route to the foam port.

A therapeutic substance dispensing shower head system has a shower head and a therapeutic substance carrying cartridge that is removably inserted into the shower head to diffuse the therapeutic substance into the water flowing through the shower head. The cartridge is configured for single hand manipulation and is inserted into a cartridge socket that is provided in the face of the shower head to make operation simple. The diffusion rate of the substance into the water flow is variably controlled by turning the cartridge while it is inserted in the cartridge socket. The diffusion is not predicated on aspiration or venturi concepts and thus is not sensitive to different water pressures and flow rates.

A dosing dispenser system and a dosing dispenser include a rotatable control configured to allow a user to select a desired mixing ratio for a product contained in a container attached to the dosing dispenser with a transport medium, such as water, flowing through the dosing dispenser.

A shower caddy includes a 4-way diverter for attachment to a shower arm and to divert water received from the shower arm to a circuit of pipes within the shower caddy. The shower caddy further includes a heating circuit within a basin. The basin holds bathing fluids, and the heating circuit transfers heat from water traveling via the circuit of pipes to the bathing fluids within the basin. The shower caddy further includes an additive infuser attached to the circuit of pipes that infuses an additive into the water flowing through the circuit of pipes when the additive infuser is activated by a user. The circuit of pipes is further connected to a showerhead that outputs the water received from the shower arm following it being used for the heating circuit and/or having an additive infused therein.

A dosing dispenser system and a dosing dispenser include a slidable control configured to allow a user to select a desired mixing ratio for a product contained in a container attached to the dosing dispenser with a transport medium, such as water, flowing through the dosing dispenser.

The embodiments disclosed herein provide a check valve aspirator including a venturi pipe having a converging section with a converging inlet and a converging outlet, and a diverging section with a diverging inlet and a diverging outlet. The converging outlet is in fluid communication with the diverging inlet. An outlet channel is in fluid communication with the venturi pipe and has an outlet port.

An aerosol perfume dispenser that uses a negative pressure pipette in communication with a fragrance bottle and a gas delivery device to continuously deliver gas over the top side of the negative pressure pipette for causing a venturi effect to generate negative pressure adsorption in the negative pressure adsorption hole of the negative pressure pipette. Subject to this negative pressure adsorption effect, the molecules of the fluid fragrance are carried through the opposite drainage hole of the negative pressure pipette into the inside of an air duct around the negative pressure adsorption hole and delivered by the gas from the delivery device through an air outlet toward the outside open air. Based on the negative pressure adsorption structure, the aerosol perfume dispenser is safe in use.

A system of a special volume control manifold, containment case and changeable multi-pack solution containers for carpet cleaning and other solution needs. It is portable and relates commercial-grade mixers and a hand-carried spray wand that connects directly to a pressure system having a diluent such as water. The additives are controlled at a manifold header for precise dispersal to the sprayer wand and nozzle. The proportional flow system is made of the control manifold, a hose to each of the solution containers, a control valve for each solution container, a wand with a control valve, nozzle and means to connect an mixed solution hose, and the mixed solution hose between the wand and the manifold. This configuration facilitates the system attachment to a pressured diluent and additive solution containers to provide controlled mixing of the diluent and additive solution which is then transferred to the sprayer wand.
