A shower head with an inner core includes a shower head body, an inlet valve core assembly, an inner core assembly, and a water outlet panel. The inlet valve core assembly is fitted in an inlet valve chamber of the shower head body. A return spring of the inlet valve core assembly abuts against an inner wall of the inlet valve chamber and one end of an inlet valve core. The inner core assembly is detachably fitted inside an inner core chamber. The water outlet panel is connected with the shower head body and provided with a functional water chamber communicating with a water outlet passage. The shower head can prevent the inner core assembly from flying out of the inner core chamber due to the impact of the water flow to hurt the user.

The reusable dry erase spray paint can is a can having a removable base and a replaceable color cartridge. The can resembles an ordinary spray paint can with a nozzle on top. The base comprises a battery-operated compressor that draws air in through an inlet on the bottom of the can and forces pressurized air up into the can through the color cartridge. The color cartridge couples to the top of the base and contains a dry erase color medium. When the nozzle is depressed while the compressor is operating, a mix of dry erase color medium and pressurized air is expelled from the nozzle.

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 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.

A sprayer head may be removably mounted onto a concentrate tank of a hose end sprayer. The sprayer head may include a valve assembly having a valve body having a first axis of rotation selectively movable between a closed orientation, a wet mode orientation, and a dry mode orientation. A metering plate may include a first annular series of spaced-apart flow-metering holes with each successive respective flow-metering hole has an increasing hole diameter adapted to withdraw a selectively adjustable amount of a concentrate from the concentrate tank when the valve body is in either the wet mode orientation or the dry mode orientation. The metering plate has a second axis of rotation which is non-coaxial with the first axis of rotation.

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.

A shower head that includes a spigot having threads for the assembly of a shower hose having an entrance point with a hollow structure for the passage of a water stream, a shower head handle having a spigot connected to the inferior position of the handle, an internally embedded soap dispenser having a chamber that is positioned in the internal structure of the shower head, along with a head connection leading from the superior position of the shower head handle which is opposite of the end of the shower head handle where the spigot is connected, and also includes a pattern plate accompanied with one or more pattern hole(s).

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 dispensing attachment for a shower head 1 has an attachment means 2, 3, 4 configured to allow the dispensing attachment 1 to be removably and repeatably connected to and disconnected from a shower head in normal use without modification of the shower head; a product container 6 configured to hold a quantity of body product in use, the product container 6 comprising a water receiving aperture 7, a main body 8 within which body product is located in use, and a plurality of outlet apertures 9, the attachment means 2, 3, 4 and product container 6 further configured so that when connected to a shower head, the water receiving aperture 7 will receive at least some of the water stream from the shower head, the water stream passing through the product container 6 to intermix with the contents therein and then pass through the outlet apertures 9.

A shower head that includes a spigot having threads for the assembly of a shower hose having an entrance point with a hollow structure for the passage of a water stream, a shower head handle having a spigot connected to the inferior position of the handle, an internally embedded soap dispenser having a chamber that is positioned in the internal structure of the shower head, along with a head connection leading from the superior position of the shower head handle which is opposite of the end of the shower head handle where the spigot is connected, and also includes a pattern plate accompanied with one or more pattern hole(s).
