The utility model discloses the water route of water intaking valve switches theory of operation as follows: when the working water level of the water tank is reduced, the brush ring buoy component 22 is driven by an external mechanism to rapidly press down to squeeze out water in the brush ring inner cavity 42, and the brush ring water stopping component 21 is opened to enable water in the main water inlet flow channel 11 to enter a brush ring water channel, so that the toilet bowl is brushed. Meanwhile, the water in the inner cavity 41 of the water tank is slowly discharged through the delay small hole 51 of the delay one-way valve 5, when the water in the inner cavity 41 of the water tank is emptied, the float assembly 32 of the water tank descends, and the water tank water stop assembly 31 is opened to enable the water in the main water inlet flow passage 11 to enter the water path of the water tank. Part of water in the water channel of the water tank enters the brush ring inner cavity 42 through the brush ring water supplementing pipeline 173, and the brush ring buoy component 22 slowly floats upwards to close the brush ring water stopping component 21 because the bottom of the brush ring inner cavity 42 is closed; the other part of the water in the water channel of the water tank enters the inner cavity 41 of the water tank through the first water replenishing port 171, and the water tank working water level will rise slowly and gradually fill the inner cavity 41 of the water tank because the water discharging hole is arranged at the bottom of the inner cavity 41 of the water tank, and the float assembly 32 of the water tank floats upwards to close the water stopping assembly 31 of the water tank after the inner cavity 41 of the water tank is filled with water. When the working water level of the water tank reaches the preset height, the water level of the inner cavity 42 of the brush ring is higher than the working water level of the water tank, and the brush ring water stopping assembly 21 and the water tank water stopping assembly 31 are both in a closed state.
