Because the valve core of the drainage relief valve is elastically and movably arranged on the valve body cavity to block the water inlet, when the pressure in the cavity of the water storage tank is smaller than the pressure in the cavity when the water storage tank is full of water, the drainage relief valve blocks the water diversion valve and the hose connected with the self-cleaning structure to prevent water leakage, and when the pressure in the water storage cavity is greater than the pressure in the cavity when the water storage tank is full of water, the liquid in the water storage cavity can be communicated to the drainage relief valve through the soft channel and pushes away the valve core blocking the water inlet to release the pressure, thereby reducing the pressure in the cavity of the water storage tank. As a preferable scheme of the embodiment, the opening pressure of the drain relief valve is preferably 15KPa-25 KPa. The design only needs to arrange the drainage relief valve between the water outlet of the shunt valve and the self-cleaning structure, and compared with the embodiment, the design does not need additional hose connection, and is favorable for simplifying the layout connection of the internal pipeline of the toilet.
The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
