Estimating the term…
An automatic protection device for an inlet valve or drain valve includes an inlet, an outlet, an on-off component, a control circuit, a control component, a water level inductor of the water tank and a water level inductor of the toilet. The water level inductor of the water tank and the water level inductor of the toilet are respectively connected to the control circuit, the control circuit drives the control component, the control component is connected to the on-off component to control the on-off component to open or close, thus connecting or disconnecting the inlet and the outlet. The automatic protection device will sound an alarm and automatically cut off the water supply when the drain valve fails to discharge, or when the toilet is plugged up and is unable to drain water.
An automatic protect device when the inlet valve or the drain valve is failed or when the toilet is plugged up comprising an inlet, an outlet, an on-off component, a control circuit, a control component, a water level inductor of the water tank and a water level inductor of the toilet, the water level inductor of the water tank and the water level inductor of the toilet are respectively connected to the control circuit, the control circuit drives the control component, the control component is connected to the on-off component to control the on-off component to open or close, thus implementing the connection or the disconnection of the inlet and the outlet, thereinto, the inlet, the outlet, the on-off component, the control circuit and the control component compose a main controller, the main controller is assembled between the water resource pipe and the inlet end of the inlet valve.
