<p>Disclosed are a self-closing water saving device, method, and toilet, wherein the goal of using a high-pressure water source or a low-pressure external water source for both flushing the toilet and saving water can be satisfied. A primary valve and a secondary valve are both float control valves. The water inlet of the secondary valve is in communication with the water outlet of the primary valve; the upper edge of the float of the secondary valve is higher than the upper edge of the float of the primary valve; the upper portion of the float of the primary valve is in communication with the float of the secondary valve through a communicating vessel; the degree of opening of the unidirectional valve of the float of the secondary valve is smaller than that of the unidirectional valve of the float of the primary valve; the connecting rod mechanism of the secondary valve opens the hole on the valve cover of the secondary valve as the float floats upward, while the connecting rod mechanism of the primary valve closes the hole on the valve cover of the secondary valve as the float floats upward; the water outlet of the secondary valve is in communication with a jet-propelled orifice; the secondary valve is also provided with a water outlet trough higher than the valve port; the water outlet trough of the secondary valve is in communication with the water outlet that discharges water to the water tank; and the valve core of the secondary valve blocks both ends of the water outlet trough and the water outlet portion of the secondary valve.</p> |
