Abstract
The present invention provides a “warning device dedicated for replacing aged-filter in a handheld showerhead”, which comprises a showerhead stem, an impeller mount, an impeller, a signal circuit device and a transparent lid. The showerhead stem includes an upper adapting section, a lower adapting section, and a mounting cavity for containing parts of impeller and signal circuit device. With upper adapting section and lower adapting section, the warning device can be easily sandwiched between showerhead and filter cylinder of conventional “handheld showerhead with built-in filter”. Other than inherent measuring display for quantity of shower water and alerting function for timely replacing filter cartridge, the warning device also solves all issues of “top-heavy awkwardness”, “quickened aging fatigue” and “redundant purchase waste”, which happened in the prior arts of “handheld showerhead with filter replacing pre-alarm device” or “handheld showerhead with filter replacing pre-display device” and conventional “handheld showerhead with built-in filter”.
