[0050] like Figure 1-Figure 2 As shown, the embodiment of the present application provides a toilet flushing device 100, including a mixing flushing valve A and a water tank assembly B. The water tank assembly B includes a first water tank 7 and a second water tank 8. The first water tank 7 is provided with an overflow port 70 connected to the second water tank 8, so that the water in the first water tank 7 overflows from the overflow port 70 to the second water tank 8 to replenish the second water tank 8. Figure 6 , Fig.12 As shown, the mixing flushing valve A includes a first water inlet channel 11 and a second water inlet channel 12 , a brush ring water outlet channel 13 and a spray water outlet channel 14 , and a water replenishment water outlet channel 15 .

[0051] like Figure 8 As shown, the first water inlet channel 11 is configured to be connected to a municipal water source (tap water) to realize the tap water supply mode of the mixed flush valve A. The second water tank 8 is connected to the second water inlet channel 12 through the first booster pump P1 and supplies water to the second water inlet channel 12 to realize the boosted water supply mode of the mixed flush valve A. The water inlet end of the replenishment water outlet channel 15 is connected to the first water inlet channel 11, and the replenishment water outlet channel 15 (see Fig.12 ) is connected to the first water tank 7 and supplies water to the first water tank 7, thereby realizing the water replenishment mode of the mixing flushing valve A for the water tank assembly.

[0052] The toilet flushing device 100 of the embodiment of the present application is configured to allow the first water tank 7 to be filled with water by overflowing the second water tank 8, thereby reducing water inlet components, reducing the complexity of connection and control, and reducing costs and saving space. At the same time, the toilet flushing device 100 of the embodiment of the present application is connected to the water tank assembly B by providing a mixed flushing valve A, and the mixed flushing valve A can realize multiple working modes, further reducing the complexity of the connection.

[0053] like Figure 1-Figure 3 As shown, in this embodiment, the first water tank 7 is a small water tank mainly used for human body washing, and the second water tank 8 is a large water tank mainly used for toilet flushing. The first water tank 7 is arranged inside the second water tank 8 to save space; of course, it can also be hung outside the second water tank 8, which is not limited here.

[0054] like Figure 3 As shown, the water tank assembly B also includes a buoyancy liquid level switch 71 provided in the first water tank 7 and electrically connected to the mixing flush valve A, and a floating member 81 provided in the second water tank 8. The floating member 81 is configured to move in accordance with the water level changes in the second water tank 8, and cooperates with the buoyancy liquid level switch 71 to control the working state of the mixing flush valve A.

[0055] In this embodiment, the floating member 81 is a buoy. When the water level of the second water tank 8 drops to a predetermined water level, the floating member 81 presses against the buoyancy liquid level switch 71 to trigger a water replenishment signal. The controller D controls the drive assembly 4 to move, and the water replenishment outlet flow channel 15 of the mixing flushing valve A is opened to replenish the first water tank 7, and the first water tank 7 then replenishes the second water tank 8. When the water replenishment of the second water tank 8 is completed, the floating member 81 releases the pressure on the buoyancy liquid level switch 71. If the first water tank 7 does not need to be replenished at this time, the controller D controls the drive assembly 4 to move, and the water replenishment outlet flow channel 15 of the mixing flushing valve A is closed, and the water replenishment of the first water tank 7 is stopped.

[0056] The toilet flushing device 100 of the embodiment of the present application can feedback and control the water level inlet of the second water tank 8 by setting a buoyancy liquid level switch 71 and a floating member 81, so that the mixing flushing valve A indirectly controls the water inlet of the second water tank 8, thereby realizing the control of the water inlet and water level of the first water tank 7 and the second water tank 8, and achieving the purpose of continuous water use.

[0057] like Figure 2 , Figure 5 As shown, the mixing flush valve A includes a human body cleaning system connected to the first water tank 7, and the human body cleaning system includes a second boosting pump P2, a heating device 91, and a cleaning device 92. The second boosting pump P2 pressurizes the water in the first water tank 7 and transports it to the cleaning device 92 for cleaning the human body. The heating device 91 is used to heat the water in the first water tank 7 and supply it to the cleaning device 92.

[0058] like Figure 2 As shown, the toilet flushing device 100 of the embodiment of the present application further includes a base C installed at the port of the water tank assembly, and the mixed flushing valve A, the controller D and the human body cleaning system are all installed on the base C. By providing the base C, the aforementioned components can be integrated and installed, further reducing the complexity of the connection.

[0059] like Figure 6 , Figure 7 As shown, the mixing flushing valve A comprises a valve body 1, a first valve membrane assembly 2, a second valve membrane assembly 3 and a drive assembly 4 provided on the valve body 1. The first valve membrane assembly 2 is configured to control the on-off of the first water inlet flow channel 11, and the second valve membrane assembly 14 is configured to control the on-off of the brush ring flow channel 13 and the spray flow channel 14. The drive assembly 4 is configured to control the working states of the first valve membrane assembly 2 and the second valve membrane assembly 3.

[0060] The mixed flushing valve 100 of the embodiment of the present application realizes the selective water inlet of the first water inlet channel 11 and the second water inlet channel 12, and the selective water outlet of the brush ring channel 13 and the spray channel 14 by setting the first valve membrane assembly 2 and the second valve membrane assembly 3, so that the mixed flushing valve 100 can realize multiple water outlet modes, reliable operation and cost saving. Figure 7 , Figure 8 As shown, the first water inlet channel 11 is provided with a first pressure control chamber 110 and a first pressure relief chamber 111 connected to the first pressure control chamber 110. The first valve membrane assembly 2 includes a first back pressure diaphragm 21 that separates the first pressure control chamber 110, a first sealing assembly that blocks or opens the first pressure relief chamber 111, and a first swing rod 20 connected to the first sealing assembly. The driving assembly 4 drives the first swing rod 20 to move to control the working state of the first valve membrane assembly 2.

[0061] The first sealing assembly includes a fixed seat 27, a plugging member 24, 25 mounted on the fixed seat 27, an elastic element 26 for driving the plugging members 24, 25 to reset, and a pull rod 29 that is equipped with the plugging members 24, 25 and drives the plugging members 24, 25 to move, and the pull rod 29 is connected to the first swing rod 20. The plugging members 24, 25 in this embodiment are assembled from two parts, and of course, one part can also be used, which is not limited here. A sealing ring 28 is installed on the outer wall of the fixed seat 27 for sealing the flow channel. The first valve membrane assembly 2 also includes a water stop float 22 and an anti-blocking needle 23. When the driving assembly 4 drives the first swing rod 20 to move, the first swing rod 20 drives the pull rod 29 to move, and the pull rod 29 presses or releases the plugging members 24, 25, thereby opening or sealing the first pressure relief chamber 111, and then realizing the pressure relief or back pressure of the first pressure control chamber 110 to realize opening or blocking the first water inlet channel 11.

[0062] like Figure 7 , Figure 8As shown, the brush ring flow channel 13 is provided with a second pressure control chamber 130 and a second pressure relief chamber 131 connected to the second pressure control chamber 130. The second valve diaphragm assembly 3 includes a second back pressure diaphragm 31 that separates the second pressure control chamber 130, a second sealing assembly that blocks or opens the second pressure relief chamber 131, a second swing rod 30 connected to the second sealing assembly, and a blocking rod 3A that moves with the second sealing assembly. The driving assembly 4 drives the second swing rod 30 to move to control the working state of the second valve diaphragm assembly 3.

[0063] The second sealing assembly includes a fixed seat 37, a blocking member 34, 35 mounted on the fixed seat 37, an elastic element 36 for driving the blocking members 34, 35 to reset, and a pull rod 39 that is equipped with the blocking members 34, 35 and drives the blocking members 34, 35 to move, and the pull rod 39 is connected to the first swing rod 30. The blocking members 34, 35 in this embodiment are assembled from two parts, and of course, one part can also be used, which is not limited here. A sealing ring 38 is installed on the outer wall of the fixed seat 37 for sealing the flow channel. The second valve membrane assembly 3 also includes a water stop float 32 and an anti-blocking needle 33. When the driving assembly 4 drives the first swing rod 30 to move, the first swing rod 30 drives the pull rod 39 to move, and the pull rod 39 presses or releases the blocking members 34, 35, thereby opening or sealing the first pressure relief chamber 131, and then realizing the pressure relief or back pressure of the first pressure control chamber 130 to realize opening or blocking the brush ring flow channel 13.

[0064] The second valve membrane assembly 3 is different from the first valve mold assembly 2 in that the second valve membrane assembly has a blocking rod 3A, which can follow the movement of the second back pressure membrane 31 to block or open the spray flow channel 14. Generally, when the brush ring flow channel 13 is blocked, the spray flow channel 14 is opened; in other words, when the brush ring flow channel 13 is opened, the spray flow channel 14 is blocked, thereby realizing the brush ring and flushing functions of the toilet. The blocking rod 3A includes a rod portion 302, a blocking end portion 301 and a sealing member 303.

[0065] Of course, the second valve membrane assembly 2 can also be arranged in the spray flow channel 14 to control the on-off of the spray flow channel 14. Correspondingly, the blocking rod 3A is used to open or block the brush circle flow channel 13. In this embodiment, the first back pressure membrane 21 and the second back pressure membrane 31 are both provided with rubber pads.

[0066] like Figure 8 As shown, the driving assembly 4 includes a rotor 40 and a motor module for controlling the rotation of the rotor 40. The motor module includes a motor 41 and a sealing ring 42. The mixing flushing valve 100 also includes an end cover 1c for fixing the driving assembly 4 on the valve body 1. The first swing arm 20 and the second swing arm 30 are respectively arranged corresponding to the circumference of the rotor 40. The rotor 40 is provided with a first toggle portion 401 and a second toggle portion 402 ( Fig.14When the rotor rotates, the first toggle portion 401 can toggle or release the first swing rod 20 to control the working state of the first valve membrane assembly 2; the second toggle portion 402 can toggle or release the second swing rod 30 to control the working state of the second valve membrane assembly 3.

[0067] In the embodiment of the present application, the driving assembly 4 is rotated and installed correspondingly with the first swing arm 20 and the second swing arm 30 , so that the first valve membrane assembly 2 and the second valve membrane assembly 3 can be controlled.

[0068] like Figure 8 , Fig.12 As shown, the mixing flushing valve 100 further includes a switch assembly 5 installed on the valve body 1 and used to control the on and off of the water replenishment outlet flow channel 15. The driving assembly 4 is installed in conjunction with the switch assembly 5 and controls the working state of the switch assembly 5.

[0069] The switch assembly 5 includes a third sealing assembly for blocking or opening the water supply outlet flow channel 15, and a third swing rod 50 connected to the third sealing assembly. The driving assembly 4 drives the third swing rod 50 to move to control the working state of the switch assembly 5. The rotor 40 is provided with a third toggle portion 403 (see Fig.15 ), when the rotor 40 rotates, the third toggle portion 403 can toggle the third swing lever 50 to control the working state of the switch assembly 5. The difference between the switch assembly 5 and the first valve membrane assembly 2 and the second valve membrane 3 is that the switch assembly 5 is not provided with a back pressure component, because the water flow rate of the water replenishment outlet flow channel 15 is small, and there is no need to provide a back pressure component. Of course, the structure of the switch assembly 5 can also be the same as that of the first valve membrane assembly 2 and the second valve membrane 3, which is not limited here.

[0070] The third sealing assembly includes a fixed seat 57, a blocking member 54, 55 mounted on the fixed seat 57, an elastic element 56 for driving the blocking members 54, 55 to reset, and a pull rod 59 that is equipped with the blocking members 54, 55 and drives the blocking members 54, 55 to move, and the pull rod 59 is connected to the third swing rod 50. The blocking members 54, 55 in this embodiment are assembled from two parts. A sealing ring (not shown) is installed on the outer wall of the fixed seat 57 for sealing the flow channel. When the driving assembly 4 drives the third swing rod 50 to move, the third swing rod 50 drives the pull rod 59 to move, and the pull rod 59 presses or releases the pressure on the blocking members 54, 55 to open or block the water replenishment outlet flow channel 15.

[0071] like Figure 9-11As shown, the downstream of the first water inlet channel 11 and the second water inlet channel 12 extend vertically and are arranged side by side, the first valve membrane assembly 2 and the second valve membrane assembly 3 are arranged vertically up and down, and the drive assembly 4 is arranged between the first valve membrane assembly 2 and the second valve membrane assembly 3. The switch assembly 5 and the first valve membrane assembly 2 are arranged horizontally left and right. The above arrangement of the mixing flushing valve 100 of the embodiment of the present application is not only compact in structure, but also can realize the control of the working states of the three components of the first valve membrane assembly 2, the second valve membrane assembly 3 and the switch assembly 5 by using a single drive assembly 4.

[0072] like Figure 8 As shown, the first swing rod 20 includes a vertical connecting rod 201 and a lateral extension 202. The vertical connecting rod 201 is connected to the pull rod 29, and the lateral extension rod 202 is installed in cooperation with the circumference of the rotor 40. The second swing rod 30 and the third swing rod 50 have the same structure as the first swing rod 20, and are not described here.

[0073] like Fig.11 As shown, the outlet ports of the first water inlet channel 11 and the second water inlet channel 12 are flush. The mixing flush valve 100 further includes an anti-siphon member 6 provided at the outlet ports of the first water inlet channel 11 and the second water inlet channel 12. The valve body 1 includes a first valve body 1a and a second valve body 1b spliced ​​with the first valve body 1a in a transverse direction. The first valve body 1a and the second valve body 1b are spliced ​​to form a first pressure control chamber 110 and a second pressure control chamber 130.

[0074] like Fig.10 As shown, when the tap water brushing mode is started, water enters the first water inlet 11 (tap water inlet), the driving assembly 4 controls the switching rotor 40 to rotate clockwise, the first swing rod 20 lifts the first connecting rod 29, the pressure in the back pressure chamber of the first pressure relief chamber 111 and the first pressure control chamber 110 is less than the pressure at the water inlet end, the water flows against the first back pressure diaphragm 21, and the first water inlet channel 11 is opened. The water flows into the valve body 1 and flows out from the brushing channel 13, and the brushing channel 13 is in a normally open state.

[0075] like Fig.14 As shown, when the tap water flushing mode is started, the driving module 4 controls the switching rotor 40 to rotate counterclockwise, the first swing arm 20 lifts the connecting rod 29, the pressure relief channel 111 opens, the pressure in the back pressure chamber of the first pressure control chamber 130 is less than the pressure at the water inlet end, and the water flow lifts up the first back pressure diaphragm 21 to enter the valve body. At the same time, the second swing arm 30 of the second valve diaphragm assembly 3 is lifted, the pressure relief channel 131 opens, the pressure in the back pressure chamber of the second pressure control chamber 130 is less than the pressure at the water inlet end, the water flow lifts up the second back pressure diaphragm 31, and at the same time pulls the blocking rod 3A to block the brush ring channel 13 to stop water, so that the water flow enters the brush ring channel 14 (jet channel).

[0076] When the brush ring mode of the first booster pump P1 is started, the second water inlet channel 12 is connected to the first booster pump P1, and the first booster pump P1 pumps water into the valve body 1 and flows out from the brush ring channel 13, and the brush ring channel 13 is in a normally open state.

[0077] like Fig.11 As shown, when the spray washing mode with the first booster pump P1 pressurized water supply is adopted, water enters the second water inlet channel 12, the driving component 4 controls the switching rotor 40 to rotate counterclockwise, the second rocker arm 30 is lifted, the second pressure relief channel 131 is opened, and the pressure in the back pressure chamber of the second pressure control chamber 130 is lower than the water inlet pressure.
