Based on whether the first water inlet 301 and the second water inlet 302 are filled with water and the size of the water inlet pressure, the valve core 50 is pushed to be in the first position or the second position, so that the waterway switching device is respectively in the first state in which the first water inlet 301 is connected to the second water outlet 402 via the inner flow channel 20 and the flow passage 501, and in the second state in which the first water inlet 301 is connected to the first water outlet 401 via the flow passage 501, and the second water inlet 302 is connected to the second water outlet 402 via the inner flow channel 20.

[0033] In this embodiment, when only the first water inlet 301 is taking in water, the valve core 50 is in the first position, and the water circuit switching device is in the first state, which is suitable for the working state in which only the brush ring of the toilet discharges water to clean the pot surface; when the water inlet pressure of the first water inlet 301 is not greater than the water inlet pressure of the second water inlet 302, the valve core 50 is in the second position, and the water circuit switching device is in the second state, which is suitable for the working state in which the toilet brush ring discharges water and the jet discharges water at the same time to discharge the dirt in the toilet.

[0034] Therefore, the water circuit switching device proposed in the utility model can realize switching between different water circuits based on whether water is flowing into the first water inlet 301 and the second water inlet 302 and the size of the water inlet pressure, avoiding the use of solenoid valves and motors, and requiring no additional power supply. It has a simple structure and can reduce production and maintenance costs while meeting the water needs of toilet spray water and brush ring water.

[0035] In this embodiment, the valve core 50 is provided with a baffle 502, and the valve body 10 is provided with a receiving cavity. When the valve core 50 is located at the first position, Figure 3 As shown, the baffle 502 is located outside the accommodating cavity and the baffle 502 closes the first water outlet 401, so that only the second water outlet 402 discharges water, meeting the use requirements of single water outlet, especially, meeting the working state of the toilet only discharging water from the brush ring; when the valve core 50 is in the second position, as shown in FIG. Figure 4 As shown, the baffle 502 is located in the accommodating cavity, opening the first water outlet 401 , so that the first water inlet 301 is connected to the second water outlet 402 through the flow channel 501 .

[0036] In this embodiment, the radial dimension of the first water outlet 401 is greater than that of the second water outlet 402, so that the water flow direction of the first water outlet 401 is greater than that of the second water outlet 402, meeting the requirements of different water flow rates of different waterways and expanding its adaptability. In particular, it meets the different requirements of the brush circle waterway and the jet waterway for water flow during toilet flushing.

[0037] In this embodiment, the first water inlet 301 and the second water inlet 302 are arranged at both ends of the valve body 10, and the water inlet directions of the first water inlet 301 and the second water inlet 302 are in a relative state, and the first water outlet 401 and the second water outlet 402 are arranged on the side of the valve body 10. Further, the first water inlet 301 faces the water inlet end of the inner flow channel 20, and the second water inlet 302 faces the other side of the valve core 50, thereby pushing the valve core 50 to move in the inner flow channel 20. Further, the water outlet end of the inner flow channel 20 faces the side of the valve body 10, so that when the valve core 50 is in the first position and the second position, the water outlet end of the inner flow channel 20 can be connected to the second water outlet 402 and the first water outlet 401 respectively. Further, the inner flow channel 20 is L-shaped, so that the water pressure of the water inlet of the first water inlet 301 can act vertically on the wall surface of part of the inner flow channel 20, which is convenient for pushing the valve core 50 to move. The inner flow channel 20 may also be in other shapes, as long as the water inlet end of the inner flow channel 20 faces the first water inlet 301 and the water outlet end faces the side wall of the valve body 10 .

It also includes a return spring 60, one end of the return spring 60 abuts against the valve core 50, and the other end of the return spring 60 abuts against the cover body 102. The valve core 50 is in the second position under the action of the return spring 60. Further, the valve core 50 is provided with a first mounting groove 701, and the cover body 102 is provided with a second mounting groove 702. The two ends of the return spring 60 are respectively installed in the first mounting groove 701 and the second mounting groove 702 to prevent the return spring 60 from being displaced during the compression process and ensure its normal use.

[0039] The working principle of a waterway switching device proposed in the present invention is as follows:

[0040] When water enters the first water inlet 301, the water pressure pushes the valve core 50 to move upward, so that the first water inlet 301 is connected to the second water outlet 402 through the internal flow channel 20 and the flow channel 501. At the same time, the baffle 502 is separated from the receiving groove to close the first water outlet 401. Figure 3As shown; when the first water inlet 301 and the second water inlet 302 are simultaneously fed with water, and the water inlet pressure of the first water inlet 301 is not greater than the water inlet pressure of the second water inlet 302, the first water inlet 301 is connected to the first water outlet 401 through the flow channel 501, and the second water inlet 302 is connected to the second water outlet 402 through the inner flow channel 20, as shown Figure 4 shown.

Of course, the first water supply source can also be the pressurized water flow of the municipal water supply pressurized by the booster pump 110. The spray outlet end is provided with a spray nozzle 1001 , the brush ring outlet end is provided with a brush ring nozzle 1002 , the first water outlet 401 is connected to the spray nozzle 1001 , and the second water outlet 402 is connected to the brush ring nozzle 1002 .

[0042] The working principle of a toilet proposed by the utility model is as follows:

[0043] When only brush ring water is needed to clean the pot surface of the toilet body 80, start the booster pump 110, pressurize the water in the water tank 90, and then pass through the first water inlet 301 and the second water outlet 402, and finally spray out from the brush ring nozzle 1002; when brush ring water and jet water are needed to be discharged at the same time, start the booster pump 110 and the water inlet valve, and the water is sprayed out from the first water outlet 401 and the second water outlet 402 respectively, and finally sprayed out by the jet nozzle 1001 and the brush ring nozzle 1002, and the dirt is discharged.
