Figure 3 shown.

[0003] In the whole system, the pressure reducing valve 20 and the flushing valve 10 are generally used at the same time, and the flushing valve 10 and the pressure reducing valve 20 are generally used independently. Even if the two are connected, it is only necessary to simply connect the water inlets of the two, that is, to use a pressure reducing valve 20. Figure 4 In the combination valve shown, the two valves only share the water inlet, and other structures are not fully integrated (the flushing valve vacuum breaking device 100 and the pressure reducing valve vacuum breaking device 200 need to be independently provided on the combination valve). The overall structure is complex, the volume is large, and the cost is high. [Summary of the invention]

[0028] See Figures 5 to 8 The present invention provides a flush valve pressure reducing integrated valve, comprising a flush valve 10 and a pressure reducing valve 20. The flush valve 10 has a first water inlet channel 101, a first water outlet channel 102, and a second water outlet channel 103. The pressure reducing valve 20 includes a switch valve assembly 21 and a pressure reducing assembly 22. The flush valve 10 is also provided with a pressure reducing valve inlet channel 201 connecting the switch valve assembly 21 and the pressure reducing assembly 22. The inlet end of the pressure reducing valve inlet channel 201 is connected to the first water inlet channel 101 through a first outlet. The switch valve assembly 21 is used to block or open the first outlet. The outlet end of the pressure reducing valve inlet channel 201 is connected to the pressure reducing valve outlet channel 202 through a second outlet. The pressure reducing assembly 22 is arranged between the pressure reducing valve inlet channel 201 and the pressure reducing valve outlet channel 202.

[0029] Further, see Figures 6 to 8 The switch valve assembly 21 is disposed at the inlet end of the pressure reducing valve water inlet channel 201, which is integrated with the first water inlet channel 101 of the flush valve 10. The pressure reducing assembly 22 is disposed at the outlet end of the pressure reducing valve water inlet channel 201 and is installed in the gap between the first water outlet channel 102 and the second water outlet channel 103 of the flush valve 10. In this embodiment, the switch valve assembly 21 and the pressure reducing assembly 22 are respectively disposed on two opposite sides of the flush valve 10.

[0030] Further, see Figures 9 to 11 , also includes a vacuum breaking device 30, which has an air vent 300. The pressure reducing valve 20 and the flushing valve 10 share the air vent 300. The vacuum breaking device 30 is internally installed with a valve core A31, a valve core B32, and a valve core C33. The valve core A31 is used to connect or disconnect the passage between the water outlet channel 202 of the pressure reducing valve and the air vent 300. The valve core B32 and the valve core C33 are respectively used to connect or disconnect the passage between the first water outlet channel 102 and the air vent 300, and the passage between the second water outlet channel 103 and the air vent 300.

[0031] Furthermore, the pressure reducing valve 20 is provided with a pressure reducing valve outlet 203. The pressure reducing valve outlet channel 202 is connected to the pressure reducing valve outlet 203 through a water outlet chamber 204. The outlet end of the pressure reducing valve outlet channel 202 is provided with a third outlet 2021 connected to the water outlet chamber 204. The water outlet chamber 204 is also provided with a third air inlet 2041 connected to the air vent 300. The valve core A31 is movably installed between the third outlet 2021 and the third air inlet 2041 to block or open the third air inlet 2041. In this embodiment, the valve core A31 is provided with a first sealing member 311.

[0032] Furthermore, the first water outlet channel 102 and the second water outlet channel 103 are connected to the air vent 300 through the first air inlet 104 and the second air inlet 105, respectively. The first water outlet channel 102 and the second water outlet channel 103 are respectively equipped with valve cores B32 and C33 for blocking or opening the first air inlet 104 and the second air inlet 105. In this embodiment, the first air inlet 104 and the second air inlet 105 are both equipped with second sealing members 34, and the valve cores B32 and C33 are diaphragms.

[0033] Working process of the present invention:

[0034] When the flush valve 10 is in operation, the corresponding flush control valve on the first water outlet channel 102 or the second water outlet channel 103 is opened, allowing water to flow in through the first water inlet channel 101 and out through the first water outlet channel 102 or the second water outlet channel 103, completing the toilet flush. If a siphon occurs, the valve cores B32 and C33 disengage from the first air inlet 104 and the second air inlet 105, allowing the first water inlet channel 101 to connect to the air vent, thus breaking the vacuum.

[0035] When pressure-reducing valve 20 is in operation, the on-off valve assembly 21 and pressure-reducing assembly 22 are opened, allowing water to enter through the first water inlet channel 101. Water then flows through the pressure-reducing valve water inlet channel 201, the pressure-reducing valve water outlet channel 202, and the water outlet chamber 204, before being discharged through the pressure-reducing valve water outlet 203. When siphoning occurs, valve core A31 disengages from its position against the third air inlet 2041, connecting the pressure-reducing valve water inlet channel 201 and the first water inlet channel 101 to the air vent, thus breaking the vacuum.

[0036] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
