Abstract
A shower head with check valves is mainly composed of a rear cover, a front cover and a pressing piece. The rear cover is provided with a rear cover hole connected with a water supply pipeline. A switch controlling the shower head to be opened is arranged on the water supply pipeline. The check valves are arranged on through holes of the pressing piece. The opened end of each check valve faces a water inlet end, and the closed end of each check valve faces a water outlet end. A tearing opening is formed in the closed end of each check valve. When water flow impact exists, the tearing openings are bent and deformed in the water outlet direction, and water flow passes through the tearing openings, flows into spray holes and is sprayed outwards. When no water flow impact exists, the tearing openings reset so that negative pressure can be generated in the spray holes and water in the spray holes can be sucked, the shower head can rapidly stop dripping water downwards after the switch is turned off, and the dripping and sprinkling phenomenon caused after the switch is turned off is reduced.
