Abstract (en)
The proposed showerhead comprises a showerhead housing having a handle with a water delivery duct, and also a nozzle in the form of a head for separating a flow into jets at the end of the showerhead. Arranged inside the housing are a reservoir for a washing agent, a precisely adjustable valve for regulating the quantity of washing agent, and a filling duct for introducing gel from outside. Also arranged inside the housing are a switch for switching between a washing mode and a rinsing mode, and two check valves in the washing agent filling duct and a washing mixture delivery duct respectively. The separating head comprises, in addition to holes in the nozzle itself for allowing the passage of water, a smaller-sized mesh for mixing the washing mixture with air. In a piston delivery embodiment, the reservoir, which has a water delivery hole on the shower hose side, contains two rigidly interconnected pistons of different diameters, and the reservoir itself is formed from two volumes corresponding to the diameter of a large piston and a small piston respectively. In a spring-loaded piston delivery embodiment, the reservoir has a single diameter and, instead of a large piston, a spring is used in the reservoir, the moving end of which has a small piston attached thereto.
