Abstract

This invention relates to a handheld showerhead with a pre-warning function for replacement of filter cartridge. The design mainly includes a blade wheel set with a signal-emitting element installed in the water inlet passageway inside the showerhead, a signal receiver corresponding to the signal-emitting element, and a numeral displayer connected to the signal receiver. When the total accumulated amount of the water that has flowed through filter installed inside the handle of the showerhead reaches the maximum filtering capacity of the filter cartridge, the showerhead set will provide a pre-warning function to remind the user to replace the filter inside the showerhead handle so as to ensure the water quality.
