A hand held shower head with filter replacing alarm device comprising a shower head shell 100, a handle filter 60, an internal lid/plate 70, an impeller 80, a hood 90, a detachable alerting pod 200 and a signal circuit device 300. The shower head shell is a plastic hollow casing extruded into unitary piece and having an obverse side 101 and a reverse side 102 and a handle butt 104. A hollow water entry 105 is created in the handle butt and a receptacle 107 is inwardly created into the obverse side. An impeller well 108 with an impeller hub notch 110 is further provided. The handle filter 60 is a filter cartridge disposed in a detachable handle to be mated with a set of threads of the handle butt. The impeller is a body with plural curved vanes and two central protruding hubs being coaxially disposed at a top side and bottom side thereof respectively. A magnetic element is embedded in the top of one vane. The shower head shell 100 has a round recess socket 113 inwardly created into the reverse side to have the detachable alerting pod embedded therein. A terminal latching nick is created in the recess socket. The alerting pod is a capsule with lid and a mounting cavity formed into a hermetically watertight body having two recharging electrodes inset internal a bottom wall of the mounting cavity with each one individual end of the two recharging electrodes protruding out of the mounting cavity. The signal circuit device 300 includes a microprocessor, a LCD display circuit electrically connected to the microprocessor, a rechargeable battery electrically connected to the microprocessor, and a magnetic reed switch or Hall effect component is inset on the internal bottom side of the mounting cavity. Advantageously frequent replacement of the shower head is avoided thereby saving on resources and expense. |
