DETAILED DESCRIPTION

[0032] Combine the following Figure 1-8 The utility model is described in detail.

[0033] A water path switching device includes a valve body 10, the valve body 10 is provided with an inner flow channel 20, the valve body 10 is also provided with a water inlet 301, a first water outlet 401 and a second water outlet 402 connected to the inner flow channel 20; a slidable valve core 50 is provided in the inner flow channel 20, the valve core 50 is provided with a flow channel 501, and an elastic device 70 is provided between the valve core 50 and the valve body 10.

[0034] Specifically, when the water pressure of the water inlet 301 is not greater than the elastic force of the elastic device 70, the water circuit switching device is in the first state of the second water outlet 402; when the water pressure of the water inlet 301 is greater than the elastic force of the elastic device 70, the water circuit switching device is in the second state of the first water outlet 401. Further, when the water inlet pressure of the water inlet 301 is not greater than the elastic force of the elastic device 70, the inlet water flow cannot push the valve core 50, at which time the valve core 50 is in the first position, the water inlet 301 is connected to the second water outlet 402 through the flow channel 501, and the water circuit switching device is in the first state; when the water inlet pressure of the water inlet 301 is greater than the elastic force of the elastic device 70, the inlet water flow pushes the valve core 50 to make it in the second position, the water inlet 301 is connected to the first water outlet 401 through the inner flow channel 20 and the flow channel 501, and the water circuit switching device is in the second state.

[0035] Therefore, the water circuit switching device is based on whether the water inlet pressure of the water inlet 301 is greater than the elastic force of the elastic device 70, so that the water circuit switching device is in the first state or the second state respectively. By controlling the water inlet pressure of the water inlet 301, switching between different water circuits can be achieved, avoiding the use of solenoid valves and motors, thereby reducing production and maintenance costs while meeting the water needs of toilet spray water and brush ring water.

[0036] In this embodiment, the valve core 50 is provided with a baffle 502, and the valve body 10 is provided with a receiving cavity 1011. When the valve core 50 is located at the first position, the baffle 502 is located in the receiving cavity 1011, and the baffle 502 opens the first water outlet 401. Figure 3When the valve core 50 is in the second position, the baffle 502 is separated from the accommodating chamber 1011, and the baffle 502 closes the first water outlet 401, as shown Figure 4 shown.

[0037] In this embodiment, when the valve core 50 is in the first position, the water inlet end of the inner flow channel 20 is sealed and adapted to one end of the water inlet 301 located in the valve body 10, so as to avoid the problem of water pressure loss at the second water outlet 402 caused by water leakage from the gap between the valve core 50 and the valve body 10. Furthermore, a sealing groove is provided on the outer side of the water inlet end of the inner flow channel 20, and a sealing ring 60 is provided in the sealing groove. When the valve core 50 is in the first position, the sealing ring 60 is adapted to the water inlet 301.

[0038] In this embodiment, the valve body 10 includes a main body 101 and a cover body 102 connected to each other, an inner flow channel 20 and a water inlet 301 are provided along the axial direction of the main body 101, and a first water outlet 401 and a second water outlet 402 are provided along the radial direction of the main body 101, and the second water outlet 402 is close to the water inlet 301. The water inlet 301 faces the water inlet end of the inner flow channel 20, so that the inlet water flow can push the valve core 50 to move in the inner flow channel 20. 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 first water outlet 401 and the second water outlet 402 respectively. Further, the inner flow channel 20 is L-shaped, so that the inlet water flow of the water inlet 301 acts 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 water inlet 301 and the water outlet end faces the side wall of the valve body 10 .

[0039] In this embodiment, the elastic device 70 is a compression spring, one end of the elastic device 70 abuts against the valve core 50, and the other end of the elastic device 70 abuts against the cover body 102. Specifically, the valve core 50 is provided with a first mounting groove 801, and the cover body 102 is provided with a second mounting groove 802. The two ends of the elastic device 70 are respectively installed in the first mounting groove 801 and the second mounting groove 802 to prevent the elastic device 70 from being displaced during the compression process and ensure its normal use. In addition, the first water outlet 401 and the second water outlet 402 have different radial dimensions. Specifically, the radial dimension of the first water outlet 401 is smaller than the radial dimension of the second water outlet 402, which meets the requirements of different water outlet flow rates of different waterways and expands its adaptability.

[0040] The working principle of a waterway switching device proposed in the present invention is as follows:

[0041] When the water pressure at the water inlet 301 is not greater than the elastic force of the elastic device 70, the water flow pressure cannot push the valve core 50. At this time, the valve core 50 is in the first position, so that the water inlet 301 is connected to the second water outlet 402 through the flow channel 501. At the same time, the baffle 502 is in the accommodating cavity 1011. Figure 3 As shown; when the water inlet pressure of the water inlet 301 is greater than the elastic force of the elastic device 70, the water flow pressure pushes the valve core 50 to move, and the elastic device 70 is compressed. At this time, the valve core 50 is in the second position, and the first water inlet 301 is connected to the first water outlet 401 through the internal flow channel 20 and the flow channel 501. At the same time, the baffle 502 is separated from the accommodating chamber 1011 and closes the second water outlet 402, as shown in FIG. Figure 4 By adjusting the water inlet pressure of the water inlet 301, the water flow is switched to be ejected from the first water outlet 401 or the second water outlet 402, thereby realizing the switching between different waterways.

[0043] In this embodiment, a water tank 100 and a booster pump 120 are provided in the toilet, the water inlet 301 is connected to the water outlet of the water tank 100 through the booster pump 120, and a water inlet valve is provided in the water tank 100 for supplying water to the water tank 100. Therefore, the water supply source is the pressurized water flow after the water in the water tank 100 is pressurized by the booster pump 120. In other embodiments, it can also be the pressurized water flow of municipal water supply after the booster pump 120 is pressurized. A spray nozzle 1101 is provided at the spray water outlet end, a brush ring nozzle 1102 is provided at the brush ring water outlet end, the first water outlet 401 is connected to the brush ring nozzle 1102, and the second water outlet 402 is connected to the spray nozzle 1101.
