[0002] In the technical field of hidden water tanks of toilets, the water inlet valve and the drain valve are important components of the hidden water tank equipment of toilets, and their main function is to control the inflow and discharge of water. The traditional fixing method is usually to directly install the water inlet and drain valve on the inner wall of the toilet water tank. Although this method is simple, it has poor stability and is easy to cause the water inlet and drain valve to shake during use, affecting the use effect. In order to solve the above problems, the existing technical solution is usually to set an inlet and drain valve fixing plate on the inner wall of the toilet water tank, and then assemble the water inlet valve and the drain valve on the fixing plate through a snap structure. This design can improve the stability of the water inlet and drain valve and reduce its shaking during use. At the same time, this design can also simplify the structure of the valve fixing device, making it easier to install and disassemble. However, there are still some problems with the existing technical solutions.
