A device for installation in the water supply pipe to a bath shower head comprising a venturi aspirator connected to a vented measuring chamber, said chamber connected to a supply container for liquid additive. Restricting the vent to the measuring chamber creates a pressure differential causing additive liquid to flow into said chamber. With the vent reopened, the liquid additive flows by gravity and differential pressure into the duct connected to the venturi aspirator, mixing the air and water flowing to the shower head and producing an aerated shower spray with liquid additive dispersed therein.
The present invention is a shower device which simplifies the showering process by allocating soap, moisturizers, fragrances, and other detergent-type fluids through a shower head using the venturi concept so as to integrate the substance with the regularly dispensed water flow.
A device to air entrain and add liquid soap or some other liquid to the water stream which flows through a shower head. There is a secondary liquid additive passageway leading into a constricted reduced pressure area of the main flow passageway of the shower water. There is a container rotatably mounted in a manner to either shut off flow of the liquid soap or other liquid, or to selectively meter the flow into the main water stream by selectively aligning aspirating air holes with an aspirating air passageway that leads into the secondary passageway.
Provided in the shower spray, which may also be connected, as a hand-held shower with a handle piece (110'), to a flexible water hose, are two optionally activable reservoirs (150') and two storage and supply chambers (160') which are assigned to said reservoirs and are intended for receiving ingredients. By means of a venturi nozzle arranged in the shower spray, with appropriate setting, ambient air can be taken in through the ingredients and aromatized as a result. This aromatized air is admixed to the through-flowing water jet at the venturi nozzle. There is no need for any external, voluminous containers or complicated valve mechanisms. The quantity and type of the ingredients to be admixed can be set directly on the hand-held shower spray by a control lever and metering screws (170').
This invention will allow an individual to take a shower or bath and apply a moisturizer at the same time by moving a shaft into a particular position on the device. The movement of the shaft section will align a series of internal cavities or internal grooves to produce a vacuum in a connected bottle of moisturizer.
A chemical intake system has an aperture plate with apertures of varying fluid flow resistance all connected to a first fluid source. A first tube is connected to one of the apertures in the aperture plate and to a suction tube. A second tube is connected to a second fluid source and to the suction tube. The amount of the first fluid flowing into the suction tube is regulated by attaching the first tube to various apertures in the plate. The amount of fluid flowing through the first tube also regulates the amount of the second fluid flowing through the second tube and into the suction tube.
