Flexible handheld shower head sprayer system

摘要

The embodiments herein provide a handheld shower head sprayer with a flexible hose arrangement that automatically expands or contracts according to user convenience. The handheld shower head sprayer comprises shower arm, handheld shower sprayer, and flexible shower hose. The shower hose comprises an elastic inner tube concentrically positioned inside a non-elastic outer tube. When shower water valve is opened, water passes through the shower hose and expands the shower hose up. The radial expansion of the inner tube is constrained by maximum diameter of the outer tube. When the shower water valve is closed, the water pressure inside the shower hose is released and the shower hose automatically contracts to the unexpanded length of the hose.
