Abstract

The utility model relates to an automatic closing device capable of warning when a solar water heater is filled with water, in particular to an overflow warning automatic shut-off device of the solar water heater. When water is fed into an existing solar water heater, people need to watch over the solar water heater and close a water valve after the solar water heater is filled with water, and sometimes tap water is wasted due to negligence of people. In order to overcome the defect, on the premise that a pipeline is not changed, only one device needs to be additionally arranged. By means of the action of water gravity, a four-bar mechanism drives a water valve handle to automatically close the water valve after the solar water heater is filled with the water. By means of impact force of the water, a water wheel is impacted, a lever is poked, a pendulum spring and a steel ball are driven, a bell is struck, the bell rings to warn, and the aim of saving the water is achieved.
