This case is a kind of birds drinking device for having self water feeding function,Include: a water inlet,Use one external water source of connection； One sink,It uses and contains water,It is drunk for a small bird； One check (non-return) valve,System connects the water inlet,And it sets on the what sink； One touches tongue piece,Have a shaft,One touches piece and a protrusion,The touch piece and the protrusion system set two sides of the what shaft respectively,And the touch piece system extends in the sink,The protrusion system extends to the lower section of check (non-return) valve； Wherein,When small bird drinking-water touches the touch piece set in the what sink,System enables the protrusion of the position what shaft other side rise and push up the check (non-return) valve,Check (non-return) valve unlatching is promoted to enable the external water source that can be injected water into the sink via the water inlet,Thereby reach the effect of automatic water filling.本案為一種具自動給水功能之鳥類飲水裝置，包含：一進水口，藉以連接一外部水源；一水槽，藉以裝盛水，供一鳥兒飲用；一止逆閥，係連接該進水口，並設於該水槽上；一觸動舌片，具一轉軸、一觸動片及一凸部，該觸動片與該凸部係分別設於該轉軸之二側，且該觸動片係延伸至該水槽內，該凸部係延伸至止逆閥之下方；其中，該鳥兒飲水碰觸到設於該水槽中之該觸動片時，係令位於該轉軸另一側之該凸部升起而向上推動該止逆閥，促使該止逆閥開啟令該外部水源能經由該進水口將水注入該水槽中，藉此達到自動注水之效果。
