The invention discloses a
hand held shower head with a descaling function. The
hand held shower head comprises a shell, a waterway, a water outlet fixing base, a small water distributing disc, a largewater distributing disc, a descaling pin disc, a water outlet
surface cover and a screw. Penetrating holes are formed in the circumferential edge of the large water distributing disc. Guide
sprue pins are arranged on the back face of the descaling pin disc, guide holes are formed in one sides of the guide
sprue pins correspondingly, and descaling pins are arranged on the front face of the descaling pin disc. A nut column is arranged in the center of the back face of the water outlet
surface cover, water outlets and guide columns are formed in and arranged on the periphery of the nut column, the guide columns penetrate through the guide holes in the descaling pin disc correspondingly, and the guide
sprue pins on the upper end surface of the descaling pin disc penetrate through the penetrating holes of the large water distributing disc correspondingly. Bidirectional bevel bayonets are arranged at the upper ends of the guide sprue pins correspondingly, a guide rail is arranged at the edge of the lateral vertical face of the water outlet fixing base, arched portions and sunken portions are arranged on the guide rail, and notches are formed in the centers of the sunken portions correspondingly. The bidirectional bevel bayonets on the guide sprue pins are clamped to the guide rail. According to the
hand held shower head with the descaling function, descaling is performed by means ofthe guide rail in a guided mode, spring mounting is avoided, no other exogenous acting force exists, and the descaling function is not affected in a long time.
