Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other.

[0041] like Figure 1 . Figure 2 As shown, this embodiment of the present invention provides a mixing flush valve 100, including a valve body 1, a first valve diaphragm assembly 2, a second valve diaphragm assembly 3, a drive assembly 4, and a switch assembly 5 installed on the valve body 1. The mixing flush valve 100 can be installed in a toilet to achieve toilet flushing control.

[0042] The valve body 1 is provided with a first water inlet channel 11, a second water inlet channel 12, a spray channel 13, a brush ring channel 14, and a human body cleaning water supply channel 15. The water inlet ends of the spray channel 13, the brush ring channel 14, and the human body cleaning water supply channel 15 are all connected to the water outlet ends of the first water inlet channel 11 and the second water inlet channel 12. The human body cleaning water supply channel 15 is configured to supply water to the human body cleaning system.

[0043] The first water inlet channel 11 is configured to connect to a tap water source (tap water) to provide tap water for toilet cleaning, and the second water inlet channel 12 is configured to connect to the first booster device 7 (see reference). Figure 11 The connection provides pressurized water for flushing the toilet. In this embodiment, the pressurization device 7 is a water pump, but an air pump or similar device can also be used; it is not limited here.

[0044] The first valve diaphragm assembly 2 and the second valve diaphragm assembly 3 are both located on the valve body 1. The first valve diaphragm assembly 2 is configured to control the opening and closing of the first water inlet channel 11, and the second valve diaphragm assembly 14 is configured to control the opening and closing of the spray channel 13 and the brush ring channel 14. The switch assembly 5 controls the opening and closing of the human body cleaning water supply channel 15. The drive assembly 4 is located on the valve body 1 and is configured to control the working state of the first valve diaphragm assembly 2, the second valve diaphragm assembly 3, and the switch assembly 5.

[0045] The mixing flushing valve 100 of this embodiment of the invention achieves selective water intake through the first inlet channel 11 and the second inlet channel 12, and selective water output through the spray channel 13 and the brush ring channel 14 by setting a first valve diaphragm assembly 2 and a second valve diaphragm assembly 3. The mixing flushing valve 100 of this embodiment of the invention also includes a human body cleaning water supply channel 15 and a switch assembly 5 for controlling the human body cleaning water supply channel 15. Furthermore, a drive assembly 4 controls the spray channel 13, the brush ring channel 14, and the human body cleaning water supply channel 15. This design not only results in a compact structure but also enables multiple operating modes of the mixing flushing valve 100, ensuring reliable operation and cost savings.

[0046] like Figure 2 , Figure 3As shown, the first water inlet channel 11 is provided with a first pressure control chamber 110 and a first pressure relief chamber 111 communicating with the first pressure control chamber 110. The first valve diaphragm assembly 2 includes a first back pressure diaphragm 21 that divides the first pressure control chamber 110, a first sealing assembly that blocks or opens the first pressure relief chamber 111, and a first rocker arm 20 connected to the first sealing assembly. The drive assembly 4 drives the first rocker arm 20 to move to control the working state of the first valve diaphragm assembly 2.

[0047] The first sealing assembly includes a fixed base 27, sealing elements 24 and 25 mounted on the fixed base 27, an elastic element 26 that drives the sealing elements 24 and 25 to reset, and a pull rod 29 that is fitted with and drives the sealing elements 24 and 25 to move. The pull rod 29 is connected to the first rocker arm 20. In this embodiment, the sealing elements 24 and 25 are assembled from two parts, but they can also be assembled from a single part. The outer wall of the fixed base 27 is equipped with a sealing ring 28 for sealing the flow channel. The first valve diaphragm assembly 2 also includes a water-stop float 22 and an anti-blocking needle 23. When the drive assembly 4 drives the first rocker arm 20 to move, the first rocker arm 20 drives the pull rod 29 to move. The pull rod 29 presses against or releases the sealing elements 24 and 25, thereby opening or sealing the first pressure relief chamber 111, thus realizing the pressure relief or back pressure of the first pressure control chamber 110 to open or block the first water inlet flow channel 11.

[0048] like Figure 2 , Figure 3 As shown, the spray channel 13 is provided with a second pressure control chamber 130 and a second pressure relief chamber 131 communicating with the second pressure control chamber 130. The second valve diaphragm assembly 3 includes a second back pressure diaphragm 31 that divides the second pressure control chamber 130, a second sealing assembly that blocks or opens the second pressure relief chamber 131, a second rocker arm 30 connected to the second sealing assembly, and a blocking rod 3A that moves with the second sealing assembly. The drive assembly 4 drives the second rocker arm 30 to move in order to control the working state of the second valve diaphragm assembly 3.

[0049] The second sealing assembly includes a fixed base 37, sealing elements 34 and 35 mounted on the fixed base 37, an elastic element 36 that drives the sealing elements 34 and 35 to reset, and a pull rod 39 that is fitted with and drives the sealing elements 34 and 35 to move. The pull rod 39 is connected to the first swing rod 30. In this embodiment, the sealing elements 34 and 35 are assembled from two parts, but they can also be assembled from one part, which is not limited here. A sealing ring 38 is installed on the outer wall of the fixed base 37 for sealing the flow channel. The second valve diaphragm assembly 3 also includes a water-stop float 32 and an anti-clogging needle 33. When the drive assembly 4 drives the first swing rod 30 to move, the first swing rod 30 drives the pull rod 39 to move. The pull rod 39 presses against or releases the sealing elements 34 and 35, thereby opening or sealing the first pressure relief chamber 131, thereby realizing the pressure relief or back pressure of the first pressure control chamber 130 to open or seal the spray flow channel 13.

[0050] The second valve diaphragm assembly 3 differs from the first valve diaphragm assembly 2 in that it has a sealing rod 3A. The sealing rod 3A moves with the second back pressure diaphragm 31 to seal or open the brush ring flow channel 14. Generally, when the spray flow channel 13 is sealed, the brush ring flow channel 14 is open; conversely, when the spray flow channel 13 is open, the brush ring flow channel 14 is sealed, thus achieving the functions of the toilet's brush ring and flushing. The sealing rod 3A includes a rod portion 302, a sealing end 301, and a sealing element 303.

[0051] Of course, the second valve diaphragm assembly 2 can also be installed in the brush ring flow channel 14 to control the opening and closing of the brush ring flow channel 14. Correspondingly, the sealing rod 3A is used to open or block the spray washing flow channel 13. In this embodiment, both the first back pressure diaphragm 21 and the second back pressure diaphragm 31 are equipped with adhesive pads.

[0052] like Figure 3 As shown, the drive 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 cap 1c for fixing the drive assembly 4 to the valve body 1. The first rocker arm 20 and the second rocker arm 30 are respectively arranged corresponding to the periphery of the rotor 40, and the rotor 40 is provided with a first actuating part 401 and a second actuating part 402. Figure 9 When the rotor rotates, the first actuating part 401 can actuate or release the first rocker arm 20 to control the working state of the first valve diaphragm assembly 2; the second actuating part 402 can actuate or release the second rocker arm 30 to control the working state of the second valve diaphragm assembly 3.

[0053] In this embodiment of the invention, the rotation of the drive component 4 is correspondingly installed with the first swing arm 20 and the second swing arm 30, thereby enabling control of both the first valve diaphragm component 2 and the second valve diaphragm component 3.

[0054] like Figure 3 , Figure 7 , Figure 11 As shown, the drive assembly 4 is installed in conjunction with the switch assembly 5 and controls the working state of the switch assembly 5. The switch assembly 5 includes a third sealing assembly for blocking or opening the human body cleaning water supply channel 15, and a third rocker arm 50 connected to the third sealing assembly. The drive assembly 4 drives the third rocker arm 50 to move to control the working state of the switch assembly 5. The rotor 40 is provided with a third actuating part 403 (see Figure 1). Figure 10 When the rotor 40 rotates, the third actuating part 403 can actuate the third rocker arm 50 to control the working state of the switch assembly 5.

[0055] The difference between the switch assembly 5 and the first valve diaphragm assembly 2 and the second valve diaphragm assembly 3 is that the switch assembly 5 does not have a back pressure component. This is because the water flow rate in the human body cleaning water supply channel 15 is relatively low, making a back pressure component unnecessary. Of course, the structure of the switch assembly 5 can also be the same as that of the first valve diaphragm assembly 2 and the second valve diaphragm assembly 3, and is not limited here.

[0056] The third sealing assembly includes a fixed base 57, sealing elements 54 and 55 mounted on the fixed base 57, an elastic element 56 that drives the sealing elements 54 and 55 to reset, and a pull rod 59 that is fitted with and drives the sealing elements 54 and 55 to move. The pull rod 59 is connected to the third rocker arm 50. In this embodiment, the sealing elements 54 and 55 are assembled from two parts. A sealing ring (not shown) is installed on the outer wall of the fixed base 57 for sealing the flow channel. The switch assembly 3 also includes a water-stop float 52 and an anti-clogging pin 53. When the drive assembly 4 drives the third rocker arm 50 to move, the third rocker arm 50 drives the pull rod 59 to move. The pull rod 59 presses against or releases the pressure on the sealing elements 54 and 55 to open or block the human body cleaning water supply channel 15.

[0057] like Figures 4-6 As shown, the downstream of the first inlet channel 11 and the second inlet channel 12 extend vertically and are arranged side by side. The first valve diaphragm assembly 2 and the second valve diaphragm assembly 3 are arranged vertically upwards and downwards, and the drive assembly 4 is located between the first valve diaphragm assembly 2 and the second valve diaphragm assembly 3. The switch assembly 5 is arranged horizontally with the first valve diaphragm assembly 2. The above arrangement of the mixing flushing valve 100 of this embodiment is not only compact in structure, but also enables the control of the working state of the first valve diaphragm assembly 2, the second valve diaphragm assembly 3 and the switch assembly 5 using a single drive assembly 4.

[0058] like Figure 3 As shown, the first rocker arm 20 includes a vertical connecting rod 201 and a horizontal extension 202. The vertical connecting rod 201 is connected to the tie rod 29, and the horizontal extension rod 202 is fitted to the circumference of the rotor 40. The second rocker arm 30 and the third rocker arm 50 have the same structure as the first rocker arm 20, and will not be described in detail here.

[0059] like Figure 6 As shown, the outlet ports of the first inlet channel 11 and the second inlet channel 12 are flush. The mixing flushing valve 100 also includes an anti-siphon component 6 disposed at the outlet ports of the first inlet channel 11 and the second inlet channel 12. The valve body 1 includes a first valve body 1a and a second valve body 1b spliced ​​to the first valve body 1a in the lateral 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.

[0060] like Figure 5 As shown, when the tap water brush ring mode is activated, water (tap water) enters through the first inlet 11. The drive assembly 4 controls the switching rotor 40 to rotate clockwise, the first swing arm 20 lifts the first connecting rod 29, and 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 inlet end. The water flows over the first back pressure diaphragm 21, opening the first inlet flow channel 11. The water enters the valve body 1 and flows out through the brush ring flow channel 14, which is normally open.

[0061] like Figure 9 As shown, when the tap water flushing mode is activated, the drive module 4 controls the switching rotor 40 to rotate counterclockwise. The first swing arm 20 lifts the connecting rod 29, opening the pressure relief channel 111. The pressure in the back pressure chamber of the first pressure control chamber 130 is less than the pressure at the inlet end, and the water flow pushes up the first back pressure diaphragm 21 into the valve body. At the same time, the second swing arm 30 of the second valve diaphragm assembly 3 is lifted, opening the pressure relief channel 131. The pressure in the back pressure chamber of the second pressure control chamber 130 is less than the pressure at the inlet end, and the water flow pushes up the second back pressure diaphragm 31. Simultaneously, the sealing rod 3A is pulled to stop the water flow in the brush ring channel 14, thereby allowing the water flow to enter the spray flushing channel 13.

[0062] When the booster device 7 is activated in water supply brush ring mode, the second water inlet channel 12 is connected to the booster device 7, and the booster device 7 draws water into the valve body 1 and flows out from the brush ring channel 14. The brush ring channel is normally open.

[0063] like Figure 6 As shown, when the pressurization device 7 is activated to supply water for spraying, water enters the second water inlet channel 12, the drive component 4 controls the switching rotor 40 to rotate counterclockwise, the second swing arm 30 is lifted, the second pressure relief channel 131 is opened, 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 pushes up the second back pressure diaphragm 31, and at the same time pulls the second connecting rod 39 to stop the water in the brush ring channel 14, so that the water flow in the second water inlet channel 12 enters the spray channel 13.

[0064] like Figure 8As shown, when the human body cleaning system is started, water (tap water) enters through the first water inlet 11, the drive component 4 controls the switching rotor 40 to rotate clockwise, the third swing arm 50 is raised, and the human body cleaning water supply channel 15 is opened to supply water to the human body cleaning system.

[0065] This utility model embodiment also provides a toilet, including a toilet body (not shown) and a mixing flush valve 100 as described in any of the above embodiments, installed on the toilet body. The toilet body is provided with a brush ring interface and a spray interface (not shown). The water outlet of the spray channel 13 of the water inlet valve 100 is connected to the spray interface, and the water outlet of the brush ring channel 14 is connected to the brush ring interface. The toilet also includes a first pressurizing device 7 and a water tank 8. A second water inlet channel 12 is connected to the water outlet of the first pressurizing device 7, and the water inlet of the first pressurizing device 7 is connected to the water tank 8.

[0066] like Figure 11 As shown, the toilet includes a base 9 mounted on the toilet body, a mixing flush valve 100 mounted on the base 9 of the water tank 8, and a human body washing system on the base 9. The human body washing system includes a second pressurization device 91, a heating device 92, and a cleaning device 93. The second pressurization device 91 pressurizes the water in the water tank and delivers it to the cleaning device 93 for washing the human body. The heating device 92 heats the water in the water tank 8 and supplies it to the cleaning device 93. The cleaning device 93 is a device used for washing the human body; its specific structure can be found in existing technology and will not be described in detail here.
