A device to wash an underside of an automobile comprises a handle comprising a first end and a second end, wherein a fluid flow through the first end of the handle is regulated via a valve member, wherein the handle comprises a canister to store and dispense one or more detergents during the wash. A pipe section fixedly attached to and extending obliquely from the second end of the handle to couple with a horizontal member via an elbow section and the horizontal member comprising a spraying head positioned at a distal end of the horizontal member, wherein the spraying head comprises a plurality of nozzles to spray the fluid in the underside of the automobile during the wash. A method of washing an underside of an automobile using the device is also disclosed.

A chemical salt composition dispensing system for dispensing controlled concentrations of aqueous chemical salt compositions to a user includes an outer housing having proximal and distal ends. The outer housing includes a base member located at the distal end of the outer housing. A sieve member is releasable to and insertable into the outer housing member. A spatially adjustable positioning member is connected to the outer housing and is flexibly secured to a shower head for positioning the outer housing and the sieve member at a selected distance between a user and the shower head. The dispensing system includes a flow control mechanism connected to the base member and is manually operated by the user to control the flow rate of the aqueous chemical composition dispensed to the user.

A mixing apparatus including a mixing region can have an inlet and an outlet. The mixing region can be operable to couple with a solution housing, thereby defining a mixing chamber. A stem can extend from a surface of the mixing region and the inlet can be disposed at a distal end of the stem. A wing can disposed at a proximal end of the stem and adjacently engaged with the surface of the mixing region and have a leading edge and a trailing edge.

The irrigation system includes a threaded neck, a main chamber, a 360-degree tube coupling, a set of directional flow tubes, a flow tube nozzle adjustment, a chamber pressure control, and a pulse flow control dial. The multi-flow system is useful for providing a direct watering system in a garden will not damage or over-water plants. Further, the system decreases water loss, and helps maintain proper plant health by adding fertilizer to the system if so desired.

A spray wand for use with a chemical or chemical formulation in solid form. The wand hose end has a wand hose end valve for control of water flow from a hose. A refill cartridge having a swirl chamber may be attached to the hollow tube. The refill cartridge has at least one nub, indent and/or external channel or groove on its external surface.

The element comprises: a hollow body; a receptacle (40) for receiving a cosmetic product, housed in the hollow body; a conduit (42) for supplying water into the receptacle (40); a nozzle (50) for dispensing the mixture of water and cosmetic product from the dispensing element.

The element comprises an inner water dispensing nozzle (44), connected to the water supply conduit (42), the inner nozzle (44) protruding into the receptacle (40) to define a chamber (46) for mixing water and the cosmetic product contained in the receptacle (40).

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 dental hygiene system includes a feed line for a liquid that engages and dissolves a dental cleansing compound before being discharged from a nozzle connected to the feed line and sprayed on the teeth for cleaning.

Hand-held solid chemical applicator assemblies for various cleaning applications such as coil cleaning utilizing specially-configured chemical tablet chamber and assembly hydraulics. In some cases, the hand-held solid chemical applicator assemblies are configured to include a cylindrical flow diverter to facilitate proper chemical tablet dissolution.

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.
