Anti-clogging showerhead device

An anti-clogging showerhead device comprising a head with a surface plate defining outlet spray holes therethrough, and including a ball-adapter with a threaded section at a first end thereof configured to engage a threaded terminal portion of a supply line extending upstream of said head, said showerhead device further characterized by:

• said threaded section of said ball-adapter including an annular shoulder rest portion;
• said head is mounted on said ball-adapter at a second end of said ball-adapter;
• said head and said ball-adapter configured to define therein a continuously open water pathway from said supply line through said outlet spray holes, said ball-adapter having upstream and downstream portions wherein said ball-adapter first end is open to said supply line located generally at said upstream portion and said plate defining spray holes is located generally at said downstream portion of said water pathway;
• said ball-adapter first end having defined therethrough at least one air pathway along said water pathway upstream portion, wherein said at least one defined air pathway extends from an internal surface of said ball-adapter adjacent said water pathway to a point external of said ball-adapter and opening to generally atmospheric pressure;
• a flexible valve element extending adjacent said internal surface of said ball-adapter, said valve element having an outwardly flexed condition where it is pressed against and substantially blocks said air pathway and a generally relaxed condition where it is spaced slightly from said ball adapter inner surface and air pathway;
• said flexible valve element further including an open substantially annular mounting ring portion positioned at said annular shoulder rest portion of said ball-adapter so as to serve as a sealing washer between said ball-adapter upstream portion and said supply line threaded terminal portion;
• whereby during typical operation of said showerhead device pressure of water flowing from said open supply line along said pathway expands said flexible valve element against said at least one air pathway preventing water seepage therefrom and, when water flow is shut off upstream of said supply line, the valve element retracts to open said air pathway immediately relieving suction within said showerhead device, thus permitting water retained in said showerhead and supply line to escape rather than be retained for evaporation resulting in mineral deposits.
