Description

Technical Field

[0001] The present invention belongs to the technical field of sanitary equipment, and specifically relates to a connection structure of an intelligent sewage discharge device. Background Art

[0002] With the continuous improvement of social living standards, toilets have been widely used. Modern toilets are usually common sanitary equipment for dealing with urine and feces. The commonly seen toilets on the market usually use flushing to deal with the generated urine, feces and other dirt. However, as water resources become increasingly precious or in some occasions where it is inconvenient to use a large amount of water flow for flushing, traditional toilets are becoming less and less applicable.

[0003] In order to reduce water resource waste or be able to use toilets in occasions where it is inconvenient to use a large amount of water flow for flushing, vacuum sewage discharge technology has been widely used. Vacuum sewage discharge technology is widely applied in high-end shopping malls, high-class hotels, high-equipped public toilets and rural sewage systems. Urine and feces can be discharged through vacuum toilets; grey water used in households can be discharged through a grey water collection end via a vacuum pipeline; rural outdoor grey water collection can also be discharged through a vacuum pipeline. During the working process of the vacuum sewage discharge system, a vacuum pump makes the whole system form a vacuum. There must be an interface valve for each toilet leading to the system to isolate it from the vacuum system. One side of the interface valve is the vacuum of the system, and the other side is the normal pressure of the toilet. When flushing the toilet, the interface valve is opened, and relying on the pressure difference between the negative pressure of the system and the atmospheric pressure, the things in the toilet are taken away.

[0004] In the prior art, on the one hand, the vacuum interface valves in the above-mentioned traditional vacuum sewage discharge systems all use negative pressure as the power source, which requires the use of a vacuum pump, and the negative pressure is used to assist the sealing of the interface valve. In the case of a power outage, the vacuum interface valve cannot be opened, and the vacuum sewage discharge system cannot be used normally. The vacuum pump has a high cost and high noise; on the other hand, the existing vacuum sewage discharge systems on the market are not compatible with traditional flushing toilet systems and cannot be used in scenarios with rich water resources. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned defects existing in the existing vacuum sewage discharge systems, and provide a connection structure of an intelligent sewage discharge device for connecting various components of the intelligent sewage discharge device. The intelligent sewage discharge device uses high-pressure fluid such as tap water as the driving force, without the need to use a vacuum pump to create a vacuum. In the case of a water outage or power outage, the intelligent sewage discharge device can still be used normally. The entire sewage discharge device saves product costs and water resources, reduces noise, can be used in both negative pressure and normal pressure states, and has a wide range of applicable scenarios. Technical Solution

[0006] To achieve the above object, the present invention designs a connection structure for an intelligent sewage discharge device, which is characterized in that: the mechanical control unit includes a button water valve, a negative pressure water valve and a waterway controller. The water pump outlet of the water pump is divided into two paths. One path is connected to the pressure water inlet of the waterway controller, and the other path is connected to the energy storage tank through a check valve. The pressure water inlet of the button water valve and the negative pressure water inlet of the negative pressure water valve are both connected to the energy storage water inlet of the energy storage tank. The outlet of the button water valve and the negative pressure water outlet of the negative pressure water valve are both connected to the pressurizing water inlet of the waterway controller. The interface valve connection port of the waterway controller is connected to the water source interface of the interface valve. The interface valve water discharge port of the waterway controller is connected to the interface valve drain port on the overflow cavity in the toilet unit. The first flushing water inlet of the waterway controller is connected to the flushing port at the bottom of the toilet inner tank assembly in the toilet unit. The second flushing water inlet of the waterway controller is connected to several high-pressure nozzles on the toilet inner tank assembly in the toilet unit. The pressure relief water inlet of the waterway controller is connected to the waterway controller drain port on the overflow cavity in the toilet unit through a throttle valve. The sewage inlet of the interface valve is connected to the sewage outlet on the toilet inner tank assembly in the toilet unit. The sewage discharge port of the interface valve is connected to the interface valve sewage discharge end interface on the overflow cavity in the toilet unit.

[0007] The electrical control unit includes an electric button, a circuit board, a negative pressure fan assembly, a battery and a power adapter. The electric button and the negative pressure fan assembly are both connected to the circuit board through signal lines. The air inlet end of the negative pressure fan assembly is connected to the negative pressure fan assembly suction interface on the overflow cavity in the toilet unit. The air outlet end of the negative pressure fan assembly is connected to the negative pressure fan assembly exhaust interface on the overflow cavity in the toilet unit. The battery supplies power to the negative pressure fan assembly and the water pump. The power adapter charges the battery.

[0008] In one embodiment, the negative pressure hole on the negative pressure water valve is connected to the negative pressure water valve air outlet hole on the overflow cavity in the toilet unit.

[0009] In one embodiment, the pressure water distribution port of the waterway controller is connected to the water supply of the intelligent toilet seat assembly.

[0010] In one embodiment, the water pump is externally connected to the main water source.

[0011] In one embodiment, the power adapter is externally connected to the commercial power supply.

[0086] All the vacuum toilets on the market now use a vacuum interface valve to separate the atmosphere and the vacuum pipeline, and a vacuum pump must be used to create a vacuum in order to open the vacuum interface valve. This means that if there is a power outage, the vacuum interface valve will never be able to open and the vacuum toilet will never be able to be used. Moreover, the cost of the vacuum pump is relatively high, and it is difficult to isolate the noise during use.

[0087] To solve this problem, as shown in the appendix Figure 1a This embodiment provides an intelligent sewage discharge device, which includes a toilet unit, a mechanical control unit and an electrical control unit. When urinating, the mechanical control unit can control the corresponding water circuit timing to clean the corresponding parts of the toilet unit. When defecating, the electrical control unit cooperates with the mechanical control unit to create negative pressure to suck the dirt while controlling the corresponding water circuit timing to clean the corresponding parts of the toilet unit. At the same time, the mechanical control unit and the electrical control unit can ensure the normal use of the intelligent sewage discharge device in the case of power failure and water cut-off through their own water storage and power storage functions.

[0088] As shown in the appendix Figure 1bAs shown in the figure, the connection relationship of this intelligent sewage discharge device is as follows: The mechanical control unit includes a button water valve 1, a negative pressure water valve 2, and a water path controller 3. The water pump outlet of the water pump 4 is divided into two paths. One path is connected to the pressure water inlet of the water path controller 3, and the other path is connected to the energy storage tank 6 through a check valve 5. The pressure water inlet of the button water valve 1 and the negative pressure water valve inlet of the negative pressure water valve 2 are both connected to the energy storage water inlet of the energy storage tank 6. The outlet of the button water valve 1 and the negative pressure water valve outlet of the negative pressure water valve 2 are both connected to the pressurization water inlet of the water path controller 3. The interface valve connection port of the water path controller 3 is connected to the water source interface of the interface valve 7. The interface valve water discharge port of the water path controller 3 is connected to the interface valve drainage port on the overflow cavity 8 in the toilet unit. The first flushing water inlet of the water path controller 3 is connected to the flushing port at the bottom of the toilet inner tank assembly 9 (mainly including the toilet inner tank) in the toilet unit. The second flushing water inlet of the water path controller 3 is connected to several high-pressure nozzles 10 on the toilet inner tank assembly 9 in the toilet unit. The pressure relief water inlet of the water path controller 3 is connected to the water path controller drainage port on the overflow cavity 8 in the toilet unit through a throttle valve 11. The sewage inlet of the interface valve 7 is connected to the sewage outlet on the toilet inner tank assembly 9 in the toilet unit. The sewage discharge port of the interface valve 7 is connected to the interface valve sewage discharge end interface on the overflow cavity 8 in the toilet unit; The electrical control unit includes an electric button 12, a circuit board 13, a negative pressure fan assembly 14, a battery 15, and a power adapter 16. The electric button 12 and the negative pressure fan assembly 14 are both connected to the circuit board 13 through signal lines. The air inlet end of the negative pressure fan assembly 14 is connected to the negative pressure fan assembly suction interface on the overflow cavity 8 in the toilet unit. The air outlet end of the negative pressure fan assembly 14 is connected to the negative pressure fan assembly exhaust interface on the overflow cavity 8 in the toilet unit. The battery 15 supplies power to the negative pressure fan assembly 14 and the water pump 4. The power adapter 16 charges the battery 15. The negative pressure hole on the negative pressure water valve 2 is connected to the negative pressure water valve air outlet hole on the overflow cavity 8 in the toilet unit. The pressure water distribution port of the water path controller 3 is connected to the water supply on the intelligent toilet seat assembly. The water pump 4 is externally connected to the total water source. The power adapter 16 is externally connected to the commercial power supply.

[0089] The following further details the installation connection methods, structures, and functions of each component in the intelligent sewage discharge device with reference to the accompanying drawings.

[0090] As shown in the attached Figure 1c figure, the toilet unit includes an intelligent toilet seat assembly 17, a toilet body assembly 18, and an overflow cavity 8. One end side of the intelligent toilet seat assembly 17 is fixedly installed at the corresponding position on the upper end of the toilet body assembly 18. The overflow cavity 8 is located in the inner cavity of the toilet body assembly 18. The toilet body assembly 18 and the overflow cavity 8 are connected by a magnetic attraction method. As shown in the attached Figure 1d and 1eAs shown, the electric button 12 and the button water valve 1 of the control unit red in the mechanical control unit and the electric control unit are installed on one side of the intelligent toilet seat assembly 17. In this embodiment, for the convenience of operation, the electric button 12 and the button water valve 1 are installed on the right side of the intelligent toilet seat assembly 17. The execution units of the mechanical control unit and the electric control unit are placed on one side of the overcurrent cavity and located in the inner cavity of the toilet body assembly 18.

[0091] As shown in the appendix Figure 1c , 1d and 1e, a more specific installation structure is as follows: one end side of the intelligent toilet seat assembly 17 is locked and installed in the threaded installation hole 1801 at the upper end of the toilet body assembly 18 through the screw 19. The threaded installation hole 1801 is covered with a decorative cover 20. An installation buckle 1802 is provided on the upper end side of the toilet body assembly 18, and a buckle hole 1701 is provided at the corresponding position on the intelligent toilet seat assembly 17. The installation buckle 1802 is snapped into the buckle hole 1701. A number of iron screws 21 are arranged at the bottom of the toilet body assembly 18, and a perforated round magnet 22 is provided at the corresponding position on the overcurrent cavity 8 corresponding to the number of iron screws 21.

[0092] Furthermore, as shown in the appendix Figure 2a , 2b and 2c, the toilet body assembly 18 includes a toilet inner tank 18a, an inner tank bracket 18b and a toilet outer shell 18c. The toilet inner tank 18a is fixedly installed in the corresponding inner tank groove of the inner tank bracket 18b, and the inner tank bracket 18b is fixedly installed in the inner cavity of the toilet outer shell 18c. As shown in the appendix Figure 5a and 5b shown, the inner tank bracket 18b fixes the toilet inner tank 18a in its corresponding inner tank groove from bottom to top along the upper edge side with the screw 23. As shown in the appendix Figure 6a , 6b, 6c, 6d, an iron screw installation hole 18c01 is provided at the bottom of the toilet outer shell 18c. A number of iron screws 21 pass through the iron screw installation hole 18c01 and are fixed corresponding to the perforated round magnet 22 with a flat washer 24 and a nut 25. The inner tank bracket 18b and the toilet outer shell 18c are locked together with the screw 26 at the bottom of the toilet outer shell 18c. As shown in the appendix Figure 4a , 4b, 4c, screw installation holes 18a01 corresponding to the toilet outer shell 18c are provided on the toilet inner tank 18a. The screw 27 passes through the screw installation holes 18a01 to lock and install the toilet outer shell 18c and the toilet inner tank 18a together. Among them, the installation buckle 1802 on the toilet inner tank 18a is fixed with a buckle screw 28 and an expansion nut 29. As shown in the appendix Figure 4a shown, three high-pressure nozzles 10 are installed on the inner surface of the toilet inner tank 18a, and the high-pressure nozzles 10 are fixed with nuts 30. As shown in the appendix Figure 4d, As shown in 4e, 4f, and 4g, in this embodiment, the high-pressure nozzle 10 includes a nozzle head 10a, which is inserted into the nozzle head mounting hole 10b01 of the threaded fastener 10b, and the nozzle head screw 10c presses the nozzle head 10a and the threaded fastener 10b to be fixedly connected. A first nozzle head seal ring 10d is installed between the end face of the head of the nozzle head screw 10c and the nozzle head 10a to prevent water seepage. A second nozzle head seal ring 10e is installed in the groove on the end face of the nozzle head 10a to seal the end face where the nozzle head 10a touches the threaded fastener 10b. Water flows from the nozzle water inlet 10f on the threaded fastener 10b through the nozzle through hole 10g on the threaded fastener 10b and then shoots out from the high-pressure nozzle passage 10h on the nozzle head 10a.

[0093] As shown in the appendix Figure 7a, as shown in Figures 7b and 7c, the button water valve 1 in the mechanical control unit includes a button unit 1-a and a water valve unit 1-b. The button unit 1-a includes a button housing 1-1. One end of a key 1-2 is placed in the inner cavity of the button housing 1-1. The key 1-2 can slide back and forth in the inner cavity of the button housing 1-1. A permanent magnet 1-3 is installed on the key 1-2. During the process of the permanent magnet 1-3 sliding back and forth in the inner cavity of the button housing 1-1 with the key 1-2, it can drive the corresponding movement of the iron core in the water valve unit 1-b. The water valve unit 1-b includes a water valve housing 1-7. One end of an iron core assembly 1-b1 is installed in the inner cavity of the water valve housing 1-7, and the other end extends into the button housing 1-1. A switch execution assembly 1-b2 is arranged in the water valve housing 1-7. The switch execution assembly 1-b2 and the partition rib 1-701 in the inner cavity of the water valve housing 1-7 divide the inner cavity of the water valve housing 1-7 into a pressure balance chamber 1-7a, a pressure charging chamber 1-7b, and a pressure relief chamber 1-7c. A pressure inlet 1-702 and an outlet 1-703 are arranged on the water valve housing 1-7. The pressure inlet 1-702 is in constant communication with the pressure balance chamber 1-7a and the pressure charging chamber 1-7b. The outlet 1-702 is in constant communication with the pressure relief chamber 1-7c. The iron core assembly 1-b1 can close or open a pressure relief hole 1-I on the switch execution assembly 1-b2 for communicating the pressure balance chamber 1-7a and the pressure relief chamber 1-7c. Further, the iron core assembly 1-b1 includes an iron core housing 1-b101. One end of the iron core housing 1-b101 is fixed in the water valve housing 1-7, and the other end extends into the inner cavity of the button housing 1-1 and is located in a guide groove in the key 1-2. An iron core 1-b102 is installed in the iron core housing 1-b101. One end of the iron core 1-b102 is connected with an iron core reset part two 1-b103 and corresponds to the permanent magnet 1-3. The other end is equipped with a silica gel head 1-b104 and corresponds to the pressure relief hole 1-I on the switch execution assembly 1-b2. The iron core 1-b102 can move back and forth in the iron core housing 1-b101 under the action of the permanent magnet 1-3 and the iron core reset part two 1-b103. The silica gel head 1-b104 can close or open the pressure relief hole 1-I during the movement of the iron core 1-b102. In this embodiment, the switch execution assembly 1-b2 is a diaphragm assembly. The pressure inlet is in constant communication with the pressure balance chamber 1-7a through an upper pressure hole 1-III on the diaphragm assembly. The pressure relief hole 1-I and the upper pressure hole 1-III are arranged on a diaphragm disk 1-b202. The aperture of the upper pressure hole 1-III is smaller than the aperture of the pressure relief hole 1-I, which can ensure that a pressure difference is formed between the pressure balance chamber 1-7a and the pressure charging chamber 1-7b after the pressure relief hole 1-I is opened. Specifically, the upper pressure hole III is a capillary hole. In the original state: As shown in Appendix Figure 7bAs shown, the silicone head 1-b104 seals the pressure relief hole 1-I. After the pressure water enters through the pressure water inlet 1-702, it will fill the pressure charging chamber 1-7b. At the same time, the pressure water will enter the pressure-equalizing chamber 1-7a through the upper pressure hole 1-III. At this time, since the force-bearing area of the pressure-equalizing chamber 1-7a is larger than the force-bearing area of the pressure-charging chamber 1-7b, and the water pressures of both are the same, the pressure of the pressure-equalizing chamber 1-7a is greater than the pressure of the pressure-charging chamber 1-7b, and the diaphragm 1-b201 is maintained in the original state. The pressure-charging chamber 1-7b is isolated from the pressure-releasing chamber 1-7c by the diaphragm 1-b201.

[0094] When the button water valve 1 is in the started state, press the button 1-2, and when the permanent magnet 1-3 descends and approaches the iron core 1-10, the iron core 1-b102 will instantly overcome the reset part 1-b103 and move upward, thereby opening the pressure relief hole 1-I, so that the pressure water inside the equalizing chamber 1-7a flows into the pressure relief chamber 1-7c through the pressure relief hole 1-I. At this moment, the equalizing chamber 1-7a is instantly depressurized, so that the water pressure is zero, and the pressure charging chamber 1-7b remains pressurized. Since the aperture of the upper pressure hole 1-III is extremely small compared to the pressure relief hole 1-I, the pressure water has no time to replenish the equalizing chamber 1-7a, and the diaphragm 1-b201 is affected by the upper and lower pressure differences, driving the diaphragm plate 1-b202 to move upward instantly, thereby opening the flow channel 1-II, so that the pressure water inlet 1-702 and the water outlet 1-703 are directly connected through the flow channel 1-II, and the pressure water is released through the water outlet 1-703 as shown in the attached figure. Figure 7c shown.

[0095] When the button water valve 1 is in the restored state, the button 1-2 is released, and the permanent magnet 1-3 and the button 1-2 are rebounded under the reset force of the reset member 1-4, and the permanent magnet 1-3 moves away from the iron core 1-b102. Under the action of the reset member 1-b103, the iron core 1-b102 moves down to seal the pressure relief hole 1-I, and the pressure water is replenished into the equalizing pressure chamber 1-7a through the upper pressure hole 1-III, so that the pressure of the equalizing pressure chamber 1-7a is greater than the pressure of the charging chamber 1-7b again, and the diaphragm 1-b201 drives the diaphragm disk 1-b202 to move down and restore to the original state, and the diaphragm 1-b201 seals the flow channel 1-II, and the pressure water inlet 1-702 is isolated from the water outlet 1-703, and no water flows out of the water outlet 1-703 as shown in the attached figure. Figure 7b shown.

[0096] As attached Figure 3aAs shown in FIGS. , 3b, and 3c, the execution unit includes a waterway controller 3, an interface valve 7, a power adapter 16, a battery 15, an overcurrent cavity 8, a power supply installation box 31, a water pump 4, a sealing cover 32, a circuit board 13, an energy storage tank 6, a circuit board installation box 33, a negative pressure water valve 2, a negative pressure water valve bracket 34, and a negative pressure fan assembly 14.

The circuit board 13 is placed in the circuit board installation box 33 and sealed with the sealing cover 32 to prevent moisture. The power adapter 16 and the battery 15 are placed in the power supply installation box 31. The sewage inlet 7a of the interface valve 7 is connected to the sewage discharge port 18a03 of the toilet inner tank 18a at its upper flange 701a by screws and nuts 35, and a suction inlet sealing ring 36 is provided at the interface connection to prevent air leakage and water leakage at the sewage inlet 7a. The sewage discharge port 7b of the interface valve 7 is sleeved with a discharge port sealing ring 37, and the sewage discharge port 7b of the interface valve 7 sleeved with the discharge port sealing ring 37 is inserted into the interface valve discharge end interface on the overcurrent cavity 8. The water pump 4 is locked to the bottom plate of the overcurrent cavity 8 with screw three 38. The waterway controller 3 is installed on the waterway controller installation guide rail on the surface of the overcurrent cavity 8 shell. The negative pressure water valve bracket 34 is fixedly installed on the stepped side of the overcurrent cavity 8 shell with bracket screws 39, and the negative pressure water valve 2 is fixedly installed on the negative pressure water valve bracket 34 with negative pressure water valve screws 40. The installation position of the energy storage tank 6 is flexible, and a rigid pipe is provided at its installation port for connection to the corresponding pipeline.

[0097] Among them, as shown in the attached Figure 9aAs shown in FIGS. 0, 9b, and 9c, the waterway controller 3 includes a waterway controller housing 3-1. The inner cavity of the waterway controller housing is partitioned into several chambers, which include an interface valve stamping chamber 3-a, an interface valve pressure relief chamber 3-b, a first flushing opening and closing chamber 3-c, a first flushing chamber 3-d, a pressure water opening and closing chamber 3-e, a pressure water chamber 3-f, a second flushing opening and closing chamber 3-g, an atmospheric pressure chamber 3-h, and a stamping start chamber 3-i. The interface valve stamping chamber 3-a and the interface valve pressure relief chamber 3-b are connected through a first passage 3-I. The interface valve stamping chamber 3-a and the first flushing opening and closing chamber 3-c are connected through a second passage 3-II. The first flushing opening and closing chamber 3-c and the first flushing chamber 3-d are connected through a third passage 3-III. The first flushing opening and closing chamber 3-c and the pressure water opening and closing chamber 3-e are connected through a fourth passage 3-IV. The pressure water opening and closing chamber 3-e and the pressure water chamber 3-f are connected through a fifth passage 3-V. The pressure water chamber 3-f and the second flushing opening and closing chamber 3-g are connected through a sixth passage 3-VI. A diaphragm assembly 3-j partitions the space in the inner cavity of the waterway controller housing 3-1 below the second flushing opening and closing chamber 3-g into an atmospheric pressure chamber 3-h and a stamping start chamber 3-i. Specifically, in this embodiment, the second passage 3-II and the fourth passage 3-IV are kept in an open state. An interface valve connection port 3-101 for connecting an interface valve is provided at the position corresponding to the interface valve stamping chamber 3-a on the waterway controller housing 3-1. An interface valve water discharge port 3-102 is provided at the position corresponding to the interface valve pressure relief chamber 3-b on the waterway controller housing 3-1. A first flushing port 3-103 is provided at the position corresponding to the first flushing chamber 3-d on the waterway controller housing 3-1. A pressure water port 3-104 and a pressure water distribution port 3-105 are respectively provided at the position corresponding to the pressure water chamber 3-f on the waterway controller housing 3-1. A second flushing port 3-106 is provided at the position corresponding to the second flushing opening and closing chamber 3-g on the waterway controller housing 3-1. A pressure charging port 3-107 and a pressure relief port 3-108 are respectively provided at the position corresponding to the stamping start chamber 3-i on the waterway controller housing 3-1. An atmospheric pressure air port 3-109 is provided at the position corresponding to the atmospheric pressure chamber 3-h on the waterway controller housing 3-1. A first shaft seal assembly 3-2 is provided at the first passage 3-I, and the first shaft seal assembly 3-2 is connected with a first return spring 3-3. A second shaft seal assembly 3-4 is provided at the third passage 3-III, and the second shaft seal assembly 3-4 is connected with a second return spring 3-5. Shaft seal pairs 3-6 are correspondingly provided at the fifth passage 3-V and the sixth passage 3-VI.Specifically, in this embodiment, one end of the main shaft 3-7 of the waterway controller is connected to the diaphragm assembly 3-j, and the other end is connected with a first return spring 3-8. The main shaft 3-7 of the waterway controller can move back and forth in the inner cavity 3-1 of the waterway controller housing under the action of the diaphragm assembly 3-j and the first return spring 3-8. Specifically, in this embodiment, the diaphragm assembly 3-j includes a diaphragm 3-j01. The atmospheric pressure chamber h and the stamping start chamber 3-i are separated by the diaphragm 3-j01. A diaphragm gasket 3-j02 is placed on the diaphragm 3-j01 and moves synchronously with the diaphragm 3-j01. One end of the main shaft 3-7 of the waterway controller is inserted into the diaphragm gasket 3-j02. This structure can ensure the pressure difference between the atmospheric pressure chamber 3-h and the stamping start chamber 3-i. To increase the tightness, the waterway controller 3-7 is equipped with a controller sealing ring at the corresponding connection.

[0098] In the original state, as shown in the appendix Figure 9d : Pressure water is introduced into the pressure water inlet 3-104, other water using inlets are connected to the pressure water outlet 3-105, the interface valve connection port 3-101 is connected to the interface valve, the button is connected to the pressure charging water inlet 3-107, and the pressure relief water outlet 3-108 is connected to the flow regulating valve. At this time, the first passage 3-I is sealed by the first shaft seal assembly 3-2, and the interface valve stamping chamber 3-a and the interface valve pressure relief chamber 3-b are isolated; the third passage 3-III is sealed by the second shaft seal assembly 3-4, and the first flushing opening and closing chamber 3-c is isolated from the first flushing chamber 3-d; the fifth passage 3-V is opened; the sixth passage 3-VI is sealed by one side end of the shaft seal pair assembly 3-6, and the pressure water chamber 3-f is isolated from the second flushing opening and closing chamber 3-g; the second passage 3-II and the fourth passage 3-IV are always open. The pressure water chamber 3-f is filled with pressure water, the fifth passage 3-V, the fourth passage 3-IV, and the second passage 3-II are in the open state, and the pressure water fills the first flushing opening and closing chamber 3-c and the interface valve stamping chamber 3-a.

[0099] In the fully open state, as shown in the appendix Figure 9e : When the button is pressed instantaneously, pressure water enters the pressure charging start chamber 3-i, and the shaft seal retaining rings two 3-11 at various positions on the main shaft of the waterway controller move upward to the bottom along with the main shaft 3-7 of the waterway controller. The first shaft seal assembly 3-2, the second shaft seal assembly 3-4, and the shaft seal pair assembly 3-6 all move upward in sequence. The sixth passage 3-VI, the third passage 3-III, and the first passage 3-I are opened successively, and the fifth passage 3-V is sealed by one side end of the shaft seal pair assembly 3-6. At this time, the water inside the interface valve flows through the first passage 3-I to the interface valve pressure relief chamber 3-b and flows out through the interface valve water discharge port 3-102. At this time, the interface valve is opened. The pressure water flows through the sixth passage 3-VI to the second flushing opening and closing chamber 3-g and flows out through the second flushing water outlet 3-106, realizing the flushing link of the second flushing water outlet 3-106.

[0100] During the delayed recovery state: As shown in the appendix Figure 9f When the shutdown button is closed, the external pressurized water is isolated from the pressurized start-up chamber 3-i. The pressurized water inside the pressurized start-up chamber 3-i slowly flows out through the capillary of the pressure relief water port 3-108. The main shaft 3-7 of the waterway controller moves downward under the action of the return spring 3-8. The shaft seal retaining ring 3-11 at each part on the main shaft 3-7 of the waterway controller slowly moves downward along with the main shaft 7 of the waterway controller. At this time, the first passage 3-I is sealed by the first shaft seal assembly 3-2, the pressurization chamber 3-a of the interface valve is isolated from the pressure relief chamber 3-b of the interface valve, and the water inside the interface valve cannot continue to drain.

[0101] Continue the delayed recovery: As shown in the appendix Figure 9g When the shaft seal retaining ring 3-11 at each part on the main shaft of the waterway controller continues to move downward, due to the different distances between the shaft seal retaining ring 3-11 and the corresponding shaft seal assemblies, the moving shaft seal in the fifth passage 3-V opens, the pressure water opening and closing chamber 3-e communicates with the pressure water chamber 3-f, and the pressure water opening and closing chamber 3-e communicates with the first flushing opening and closing chamber 3-c via the fourth passage 3-IV. At this time, the first flushing opening and closing chamber 3-c communicates with the first flushing chamber 3-d, and the pressurized water flows out through the first flushing water port 3-103, realizing the flushing process of the first flushing water port 3-103. The pressure water chamber 3-f and the second flushing opening and closing chamber 3-g are closed by the other end of the shaft seal pair assembly 3-6, and the pressurized water cannot flow to the second flushing opening and closing chamber 3-g via the sixth passage 3-VI, and the pressure water at the second flushing water port 3-106 stops flowing out.

[0102] Restore the original state: As shown in the appendix Figure 9h When the shaft seal retaining ring 3-11 continues to move downward to the bottom along with the main shaft 3-7 of the waterway controller, the first flushing opening and closing chamber 3-c and the first flushing chamber 3-d are closed by the second shaft seal assembly 3-4, and the pressurized water cannot flow to the first flushing opening and closing chamber 3-c via the third passage 3-III, and the pressure water at the first flushing water port 3-103 stops flowing out; the pressurized water can only flow to the pressurization chamber 3-a of the interface valve via the fifth passage 3-V, the fourth passage 3-IV, and the second passage 3-II. The pressurized water flows to the interface valve via the interface valve connection port 3-101, and the interface valve closes.

[0103] As shown in the appendix Figure 8a and 8bAs shown, the interface valve 7 includes a driving unit 7-a and a sewage discharging unit 7-b. The driving unit 7-a can drive the opening and closing of the sewage inlet of the sewage discharging unit 7-b through a linkage mechanism 7-c. The driving unit 7-a includes a driving housing 7-1. A diaphragm assembly 7-2 divides the inner cavity of the driving housing 7-1 into an upper chamber 7-101 and a lower chamber 7-102. The diaphragm assembly 7-2 can move up and down in the inner cavity of the driving housing 7-1. The upper chamber 7-101 is connected to the outside through a water source interface 7-103. A reset member 7-3 is arranged in the lower chamber 7-102 to provide a reset force for the upward movement of the diaphragm assembly 7-2. More specifically, one end of the interface valve main shaft 7-4 in the linkage mechanism 7-c is fixedly connected to the diaphragm assembly 7-2. The diaphragm assembly 7-2 includes a diaphragm 7-201. The diaphragm 7-201 is placed on a diaphragm cover 7-202. One end of the interface valve main shaft 7-4 passes through the diaphragm cover 7-202 and is locked with a nut 7-5. A protective cover 7-6 is installed at the position where the interface valve main shaft 7-4 passes through the diaphragm cover 7-202 and is locked with the nut 7-5. Specifically, as shown in the appendix Figure 8c and 8dAs shown, the other end of the interface valve main shaft 7-4 passes through the bottom of the drive housing 7-1 and extends into the sewage discharge unit 7-b. The other end of the interface valve main shaft 7-4 passes through the bottom of the drive housing 7-1 and extends into the sewage discharge housing 7-9 in the sewage discharge unit 7-b, where it is hinged to a lever 7-7. One end of the lever 7-7 is provided with a first rotating shaft 7-10, and the first rotating shaft 7-10 is installed in a first groove 7-901 on the sewage discharge housing 7-9 and can rotate. Among them, it is preferred that the first rotating shaft 7-10 can only rotate when installed in the first groove 7-901 on the sewage discharge housing 7-9. The other end of the lever 7-7 is provided with a roller shaft 7-11, and a roller 7-12 is installed on the roller shaft 7-11. The roller shaft 7-11 is installed in sliding grooves 7-801 on both sides of the back of the flap 7-8, and the roller shaft 7-11 can roll in the sliding grooves 7-801, and the roller 7-12 can roll between the sliding grooves 7-801 on both sides of the back of the flap 7-8. An arc surface 7-802 matching the outer shape of the roller 7-12 is provided at the bottom of the part between the sliding grooves 7-801 on both sides of the back of the flap 7-8. A second rotating shaft 7-13 is provided on one side of the flap 7-8, and the second rotating shaft 7-13 is installed in a second groove 7-902 on the sewage discharge housing 7-9 and can rotate. In this embodiment, it is preferred that the second rotating shaft 7-13 can only rotate when installed in the second groove 7-902 on the sewage discharge housing 7-9. A gas port 7-104 is provided on the drive housing 7-1 corresponding to the lower chamber 7-102, and this gas port 7-104 is used to communicate with the outside. When needed, it can also be used to connect to an external air pump to provide high-pressure air flow. Specifically, a shaft seal 7-14 is installed between the interface valve main shaft 7-4 and the bottom of the drive housing 7-1 to ensure the seal between the drive housing 7-1 and the sewage discharge housing 7-9. A linear bearing 7-15 is installed on the part of the interface valve main shaft 7-4 located inside the drive housing 7-1. Specifically, the other end of the interface valve main shaft 7-4 is connected to the lever 7-7 by a pin 7-26 to form a hinge connection. The pin 7-26 passes through an oblong hole 7-701 provided on the lever 7-7, and the shape of the oblong hole 7-701 corresponds and fits with the movement track of the hinge point between the interface valve main shaft and the lever during the movement of the lever 7-7, thus ensuring that the interface valve main shaft and the lever 7-7 will not be stuck, or the flap 7-8 cannot seal the sewage discharge port 7-904. A clip 7-30 is locked on the front of the flap 7-8 by self-tapping screws 7-29, and a gasket 7-31 is clamped between the flap 7-8 and the clip 7-30 to further improve the sealing performance when the sewage inlet 7-903 of the sewage discharge housing 7-9 is closed.

[0104] As shown in the appendix Figure 8bAs shown, when the interface valve is in its original state, i.e., the interface valve is open circuit, high-pressure water (such as tap water) is introduced through the water source interface 7-103. The upper chamber 7-101 above the diaphragm 7-201 is filled with high pressure, while the lower chamber 7-102 below the diaphragm 7-201 is in communication with the outside (atmosphere or low pressure) through the gas port 7-104. This causes the pressure above the diaphragm 7-201 to be much higher than the pressure below, thereby compressing the reset member 7-3 and causing the diaphragm cover 7-202 to move downward. The interface valve main shaft 7-4 connected to the diaphragm cover 7-202 also moves downward at the same time. The other end of the interface valve main shaft 7-4 firmly presses against the lever 7-7, causing the lever 7-7 to rotate downward around the first rotating shaft 7-10. While the roller 7-12 at the other end of the lever 7-7 rolls and slides on the back of the flap 7-8, the flap 7-8 rotates downward around the second rotating shaft 7-13, thereby tightly covering the sewage inlet and isolating the sewage inlet from the sewage outlet.

[0105] As shown in the Figure 8e attachment, when the interface valve is in the startup state, i.e., the interface valve is closed circuit: The high-pressure water (such as tap water) is released through the water source interface. The reset member 7-3 immediately pushes the diaphragm cover 7-202 upward. The diaphragm cover 7-202 pulls the interface valve main shaft 7-4 upward. The interface valve main shaft 7-4 pulls the lever 7-7 to rotate upward around the first rotating shaft 7-10. The roller 7-11 at the other end of the lever 7-7 slides in the chute 7-801 on the back of the flap 7-8. The roller 7-11 causes the flap 7-8 to rotate upward around the second rotating shaft 7-13 through the chute 7-801, thereby opening the sewage inlet and making the sewage inlet communicate with the sewage outlet. In this embodiment, metal gaskets are actually installed at the joints of the interface valve to increase the sealing and reliability of the product.

[0106] As shown in the Figure 10a, As shown in Figures 10b and 10c, the negative pressure water valve 2 includes a water valve body unit 2-a. The water valve body unit 2-a is connected to a pneumatic control unit 2-b. The pneumatic control unit 2-b includes a pneumatic unit housing 2-1. A slider 2-2 is installed in the inner cavity 2-101 of the pneumatic unit housing 2-1 and can move up and down. A pressure-producing diaphragm 2-3 is tightly fastened to the upper end head of the slider 2-2 and the edge of the opening of the pneumatic unit housing 2-1 to seal the inner cavity of the pneumatic unit housing 2-1. A magnet 2-4 is installed at the lower end of the slider 2-2. The magnet 2-4 can move up and down in the inner cavity of the pneumatic unit housing 1 along with the slider 2-2. During the downward movement of the magnet 2-4, it can trigger the opening of the water valve body unit 2-a. The pneumatic unit housing 2-1 is connected to an external vacuum system through a capillary check valve 2-5. The magnet 2-4 is connected to a return spring 2-14 which can provide a return force for its upward movement. The capillary check valve 2-5 includes a check rubber cover 2-501. The check rubber cover 2-501 is installed on the side of the pneumatic unit housing 2-1. A negative pressure hole 2-501a is opened on the check rubber cover 2-501. An air flow hole 2-102 is provided on the pneumatic unit housing 2-1 corresponding to the check rubber cover 2-501. The inner cavity of the pneumatic unit housing 2-1 is connected to the outside through the air flow hole 2-102 and the negative pressure hole 2-501a. A check rubber 2-502 is inserted into the installation groove of the check rubber cover 2-501 at a corresponding position outside the air flow hole 2-102. A capillary plug 2-503 is installed in the installation groove of the check rubber cover 2-501 at a corresponding position outside the air hole on the check rubber 2-502.

[0107] As shown in the attached Figure 10b , the water valve body unit 2-a includes a water valve body valve housing 2-6. The lower end of a sealing knob 2-7 is fixedly installed on the water valve body valve housing 2-6 to form a water valve body housing. The upper end of the sealing knob 2-7 extends into a guiding hole 2-201 on the slider 2-2. A water valve core 2-8 is installed inside the sealing knob 2-7. The water valve core 2-8 can move up and down in the inner cavity of the sealing knob 2-7. A valve core spring 2-9 for auxiliary pressing is connected to the water valve core 2-8. A leading hole sealing head 2-10 is sleeved at the bottom of the water valve core 2-8. The leading hole sealing head 2-10 corresponds to a leading hole 2-1201 of a water valve sealing cover 2-12 in the inner cavity of the water valve body valve housing 2-6. During the up and down movement of the water valve core 2-8 in the inner cavity of the sealing knob 2-7, the leading hole sealing head 2-10 can seal or unseal the leading hole 2-1201 of the water valve sealing cover 2-12 in the inner cavity of the water valve body valve housing 2-6.

[0108] In this embodiment, as shown in the attached Figure 10bAs shown, a gasket 2-17 is provided between the end faces of the pneumatic unit housing 2-1 and the water valve body housing 2-11, and the gasket 2-17 is sleeved on the sealing knob 2-7, and a V-shaped sealing ring 2-15 is provided between the gasket 2-17 and the sealing knob 2-7. A sealing ring is provided between the non-return rubber cover 2-501 and the pneumatic unit housing 2-1. Undercuts are provided on both sides of the bottom of the pneumatic unit housing 2-1, and the undercuts are clamped on the water valve body housing 2-6 to achieve fixed installation of the pneumatic unit housing 2-1 and the water valve body housing 2-11.

[0109] The operation process of the negative pressure water valve 2 is as follows: the water valve sealing cover 2-12 is provided with a pressure stabilizing hole 2-1202. When pressure water is connected, the pressure water will enter the upper side of the water valve sealing cover 2-12 through the pressure stabilizing hole, so that the water pressure on the upper and lower sides of the water valve sealing cover 2-12 is balanced. The water valve sealing cover 2-12 is in a closed state. Once the pilot hole 2-1201 is opened, the water on the upper side of the water valve sealing cover 2-12 flows out from the pilot hole, and the water pressure on the upper side disappears instantly. The water pressure on the lower side opens the water valve sealing cover 2-12. The negative pressure hole 2-501a is connected to the vacuum system. When the vacuum is connected, the water valve quickly opens and is in an open valve state. When the magnet 2-4 drops to a certain position, it will trigger the water valve core 2-8 inside the water valve body to overcome the spring force of the valve core spring 2-9 and move upward, thereby opening the water valve body as shown in the attached figure. Figure 10c As shown, pressurized water flows out automatically.

[0110] As attached Figure 12a, as shown in FIGS. 12b, 12c, the negative pressure fan assembly 14 includes a high-pressure fan 14a, a fan elbow 14b, a fan fixing link ring 14c, a fan suction end joint 14d, a suction end silencing pipe 14e, an exhaust end silencing pipe 14f, and an exhaust end outer pipe 14g. Specifically, the high-pressure fan 14a is placed in the internal space formed by the combination of the fan elbow 14b and the fan fixing link ring 14c. In this embodiment, the fan elbow 14b is a 90-degree fan elbow. The fan elbow 14b and the fan fixing link ring 14c are assembled together through a snap structure 14n, and a fixing link ring O-ring 14h is provided between the fan elbow 14b and the fan fixing link ring 14c for sealing. The fan suction end joint 14d is installed on the fan fixing link ring 14c. The fan fixing link ring 14c is connected to the fan suction end joint 14d through a hook structure 14c01, and a link ring gasket 14i is provided between the fan fixing link ring 14c and the fan suction end joint 14d through the hook structure for elastic sealing; the suction end silencing pipe 14e is installed in the internal space of the fan suction end joint 14d, and a first sound-absorbing cotton 14j is stuffed in the internal space of the fan suction end joint 14d outside the suction end silencing pipe 14e. An O-ring 14k of the suction end joint is sleeved outside the fan suction end joint 14d for connecting to the suction port of the negative pressure fan assembly on the flow-through cavity 8. The exhaust end of the high-pressure fan 14a is connected to an exhaust end outer pipe 14g, the exhaust end silencing pipe 14f is installed in the exhaust end outer pipe 14g, the exhaust end outer pipe 14g outside the exhaust end silencing pipe 14f is stuffed with a second sound-absorbing cotton 14l, and a fan elbow O-ring 14m is installed between the exhaust end outer pipe 14g and the lower end of the fan elbow 14b. The fan elbow O-ring 14m is installed in the installation groove between the exhaust end outer pipe 14g and the lower end of the fan elbow 14b. The negative pressure fan assembly as a whole adopts an insertion compression sealing design, a hook compression sealing design, and a detachable snap design, which is convenient for overall installation and reduces the difficulty of disassembly and maintenance. Sound-absorbing pipes and sound-absorbing cotton are provided at both the suction end and the exhaust end of the negative pressure fan assembly, which play a role in noise reduction and silencing when the high-pressure fan is working.

[0111] As shown in the attached Figure 11a , as shown in FIGS. 11b, 11c, 11d, the flow-through cavity 8 includes a negative pressure cavity assembly 8a and a flip-up drain valve assembly 8b. One end of the flip-up drain valve assembly 8b is connected to the excrement discharge port on the negative pressure cavity assembly 8a. An inner cavity is provided in the negative pressure cavity assembly 8a. The high-pressure fan 14a can extract the air in the inner cavity from the suction port of the negative pressure fan assembly on the negative pressure cavity assembly 8a and discharge it from the corresponding exhaust duct on the negative pressure cavity assembly 8a through the exhaust port of the negative pressure fan assembly on the negative pressure cavity assembly 8a, so as to form a negative pressure air duct in the inner cavity.

[0112] As shown in the attached Figure 13aAs shown in FIGS. 0, 13b, and 13c, the negative pressure cavity assembly 8a includes a negative pressure cavity upper cover 8a01 and a negative pressure cavity lower housing 8a02. The negative pressure cavity upper cover 8a01 and the negative pressure cavity lower housing 8a02 are fixedly assembled together correspondingly. An upper inner cavity 8a01a is provided inside the negative pressure cavity upper cover 8a01, and a lower inner cavity 8a02a is provided inside the negative pressure cavity lower housing 8a02. A cavity wind deflector 8a03 separates the upper inner cavity 8a01a and the lower inner cavity 8a02a, and the upper inner cavity 8a01a and the lower inner cavity 8a02a are connected through air flow holes 8a03a on the cavity wind deflector 8a03. In this embodiment, the air flow holes 8a03a are rows of air inlet holes evenly distributed at one end of the cavity wind deflector 8a03, and these holes are used for the air inside the cavity to enter.

[0113] As shown in the attached Figure 13a figures, an upper and lower cavity sealing ring 8a04 is provided between the negative pressure cavity upper cover 8a01 and the negative pressure cavity lower housing 8a02. The negative pressure cavity upper cover 8a01 and the negative pressure cavity lower housing 8a02 are connected and closed by self-tapping screws 8a05. The cavity wind deflector 8a03 is fixedly installed on the negative pressure cavity upper cover 8a01 by self-tapping screws 8a05.

Specifically, the air intake port 8a01c of the negative pressure water valve is arranged at the top of the upper cover 8a01 of the negative pressure chamber for the air intake connection of the negative pressure water valve 2. The air suction port 8a01b of the negative pressure fan assembly is arranged on the upper side of the upper end of the upper cover 8a01 of the negative pressure chamber and is connected to the fan suction end joint 14d of the negative pressure fan assembly 14.

The discharge end interface 8a01d of the interface valve is designed at the lower end of the upper cover 8a01 of the negative pressure chamber, and the sewage discharge port of the interface valve 7 is installed here. The top surface inside the cavity is designed with water and fog removing barbs 8a01a01 so that the water molecules of the humid air flowing in the air duct inside the cavity are intercepted and blocked inside the cavity when passing through these rib positions, and finally accumulate to form water flow and fall to the bottom of the cavity, avoiding water vapor from entering the fan and affecting the service life of the fan. There are 4 cavity wind baffle screw fixing holes 8a01f arranged inside the upper cover 8a01 of the negative pressure chamber, and the cavity wind baffle 8a03 is installed and fixed on it through the self-tapping screw two 8a05. A groove matching the shape of the toilet inner tank 18a is arranged on the upper cover 8a01 of the negative pressure chamber.

[0115] As shown in the appendix Figure 15aAs shown in , 15b, 15c, 15d, 15e, the drain outlet 8a02c of the waterway controller, the exhaust outlet 8a02d of the negative pressure fan assembly, the drain outlet 8a02e of the interface valve, and the installation guide rail 8a02f of the waterway controller are arranged at the corresponding positions on the lower housing 8a02b of the negative pressure chamber corresponding to the corresponding execution unit components.

After the excrement is sucked into the cavity, under the action of gravity, it slides out through the sloping chute to the excrement discharge outlet; the water retaining rib 8a02g can be used to prevent water from splashing in the cavity. The inner cavity bottom plate 8a02b of the lower housing 8a02b of the negative pressure chamber is provided with a slope 8a02b01 to ensure that dirt remains at the bottom of the cavity and can also be discharged when there is a large amount of water flow. The inner cavity bottom plate 8a02b of the lower housing 8a02b of the negative pressure chamber is provided with anchor bolts 8a10 for installation on the ground. At the bottom edge of the lower housing 8a02b of the negative pressure chamber, there are several perforated round magnets 22 for magnetic attraction with several iron screws 21 on the toilet outer shell 18c. The outer shape of the lower housing 8a02b of the negative pressure chamber matches the toilet outer shell 18c.

[0116] As shown in the appendix Figure 16a, as shown in FIGS. 16b, 16c, 16d, 16e, 16f, the flip-up drain valve assembly 8b includes a drain valve connecting pipe 8b01. An exhaust passage 8b01a and a sewage discharge passage 8b01b are provided inside the drain valve connecting pipe 8b01. The flip-up cover 8b02 can open or close the sewage discharge passage 8b01b under the action of an external force and a magnet group. The exhaust passage 8b01a communicates with a corresponding exhaust passage on the negative pressure cavity assembly 8a and is isolated from the sewage discharge passage 8b01b. The corresponding exhaust passage refers to the passage that communicates with the air outlet 8a02d of the negative pressure fan assembly. A drain valve connecting pipe sealing groove is provided at the upper end of the drain valve connecting pipe 8b01 for installing a connecting pipe sealing ring 8b03. The drain valve connecting pipe 8b01 is connected to the excrement discharge port 8a02i on the bottom plate 8a02b of the negative pressure cavity assembly 8a through a self-tapping screw 8b09.

[0117] It should be noted that the installation positions and structures of the various components in the above intelligent sewage disposal device are only a specific embodiment of the present invention, and do not mean that the present invention can only adopt the structures described in the above embodiments to achieve the purpose of the present invention. Generally speaking, there will always be specific structures obtained based on the inspiration of the technical solution of the present invention that can still achieve the purpose of the present invention. However, it should still be considered that all specific structures obtained based on the inspiration of the technical solution of the present invention fall within the protection scope of the present invention.

[0118] The operation process of the intelligent sewage disposal device provided in this embodiment is as follows:

[0119] In the original state (i.e., when the sewage discharge work has not started yet), the water outlet of the water pump 4 is divided into two parts: one part is used for flushing the toilet by the water path controller 3, and the other part is connected to the energy storage tank 6 through a check valve. The energy storage tank 6 is used as the trigger high-pressure water for the water path controller 3. The advantage of dividing the water outlet of the water pump 4 into two parts is as follows: First, the amount of water used for flushing the toilet is much more than the amount of water used to trigger the water path controller 3. When flushing the toilet, it can ensure that the high-pressure water for triggering the water path controller 3 does not lose pressure, ensuring the normal opening of the water path controller 3. Second, when the water supply at home stops, the energy storage tank 6 stores high-pressure water, which can trigger the water path controller 3 to open, so that the high-pressure water inside the interface valve 7 is released through the water path controller 3, causing the interface valve 7 to open, and the toilet can still be used normally.

[0120] In the original state, the energy storage tank 6 is filled with high-pressure water, and the interface valve 7 is closed because it is filled with high-pressure water through the water path controller 3; the inlets of the button water valve 1 and the negative pressure water valve 2 are connected to high-pressure water and are on standby. The battery 15 is used to supply power to the components. Generally speaking, the toilet can still be normally flushed 300 times even in the case of power failure, and the power adapter charges the battery. The negative pressure fan assembly 14 does not work and is in a standby state; there is no negative pressure in the negative pressure cavity assembly 8a either; under the suction force of the magnet pair, the flap 8b02 of the flap discharge valve assembly 8b is in a closed and sealed state. The flap of the anti-backwater floor drain 8a09 is also in a closed state, and the air duct is airtight; the flap of the interface valve 7 is also in a closed state, and the odor from the sewer cannot enter the inside of the toilet.

[0121] When it is necessary to clean urine under normal water and electricity conditions: Press the button water valve 1. The water outlet of the button water valve 1 instantaneously releases high-pressure water through the energy storage tank 6 and enters the water path control 3, triggering the water path controller 3 to open instantaneously. At this time, the second flushing port of the water path controller 3 is filled with water, and the three high-pressure nozzles 10 have started to spray water to clean the toilet; the interface valve water discharge port of the water path controller 3 is also opened, and the high-pressure water inside the interface valve 7 is released through the interface valve water discharge port of the water path controller 3 and enters the overcurrent cavity 8, and the interface valve 7 opens. Release the button water valve 1, and the high-pressure water at the water outlet of the button water valve 1 is disconnected. Another interface at the bottom of the water path controller 3 is connected to a throttle valve 11. The high-pressure water filling the bottom cavity of the water path controller 3 is slowly released through the throttle valve 11. This is called the delay process. During the delay process, the water path controller 3 slowly recovers.

[0122] In the above process, the water path of the intelligent sewage discharge system changes as follows:

[0123] The second flushing port of the water path controller 3 is opened, and the three high-pressure nozzles 10 start to spray water; the interface valve water discharge port of the water path controller 3 is opened, the high-pressure water inside the interface valve 7 is released through the interface valve water discharge port of the water path control 3, and the flap of the interface valve 3 is opened;

[0124] The water outlet of the interface valve of the waterway controller 3 is closed, locking the drainage outlet of the interface valve 7;

[0125] The second flushing water inlet of the waterway controller 3 is filled with water, and the three high-pressure nozzles 10 spray water to wash the inner surface of the toilet;

[0126] The second flushing water inlet of the waterway controller 3 is disconnected, the first flushing water inlet is filled with water, and the bottom interface of the toilet inner tank is filled with water to wash the bottom of the toilet inner tank;

[0127] The first flushing water inlet of the waterway controller 3 is disconnected, the bottom of the toilet inner tank no longer sprays water, and the high-pressure water has to be filled into the interface valve 7 through the waterway controller 3. The interface valve 7 is closed again, and the system returns to the initial state.

[0128] When cleaning feces is required under normal water and electricity conditions: Press the electric button 12, and the negative pressure fan assembly 14 starts quickly. Under the high-speed rotation of the high-pressure fan, the air in the negative pressure cavity assembly 14 is sucked into the exhaust end of the fan. Under the action of the wind pressure, the flip cover of the anti-backflow floor drain 8a09 opens, and the air passes through it and enters the air duct at the bottom of the cavity. Finally, the air enters the sewer through the exhaust passage of the flap drain valve assembly 8b. This will cause the inside of the toilet flow-through cavity 8 to be quickly filled with negative pressure.

[0129] The negative pressure port of the negative pressure water valve 2 is communicated with the flow-through cavity 8. Under the action of the negative pressure, the negative pressure water valve 2 opens, and the water outlet of the negative pressure water valve 2 instantly releases high-pressure water into the waterway controller 3, and the waterway controller 3 opens;

[0130] The second flushing water inlet of the waterway controller 3 opens, and the three high-pressure nozzles 10 start to spray water; the water outlet of the interface valve of the waterway controller 3 opens, and the high-pressure water inside the interface valve 7 is released through the waterway controller 3. The flap of the interface valve 7 opens. At the moment of opening, along with the negative pressure, the dirt in the toilet is quickly sucked away and discharged through the internal household sewage pipe connected to the flow-through cavity 8;

[0131] The negative pressure fan assembly 14 stops;

[0132] The water outlet of the interface valve of the waterway controller 3 is closed, locking the drainage outlet of the interface valve 7;

[0133] The second flushing water inlet of the waterway controller 3 is filled with water, and the three high-pressure nozzles 10 spray water to wash the inner surface of the toilet inner tank;

[0134] The second flushing water inlet of the waterway controller 3 is disconnected, the first flushing water inlet is filled with water, and the bottom interface of the toilet is filled with water to wash the bottom of the toilet inner tank;

[0135] The first flushing water inlet of the waterway controller 3 is disconnected, the bottom of the toilet inner tank no longer sprays water, and the high-pressure water has to be filled into the interface valve 7 through the waterway controller 3. The interface valve 7 is closed again, and the system returns to the initial state.

[0136] When draining sewage, the flap in the flap discharge assembly 8b opens, and after draining, it automatically closes under the action of magnetic attraction.

[0137] It should be noted that when the pressure of domestic tap water is extremely low, the water pump 4 can be used to increase the pressure, and there is a flow meter in the water outlet of the water pump 4. The specific method of use is that when the second flushing port of the water circuit controller 3 is opened and the three high-pressure nozzles 10 start to spray water, the flow meter detects the flow of tap water. When the flow is extremely low, the water pump 4 starts to automatically increase the pressure of the tap water; if the flow is sufficient, the water pump 4 remains on standby and does not start.

[0138] When the power is cut off but the water supply is not cut off, the internal battery 15 can be used by the system in the power outage situation.

[0139] When there is a power outage and water shortage: during the urine cleaning process, there is still high-pressure water in the energy storage tank 6. The button water valve 1 is pressed, and the water outlet of the button water valve 1 instantly releases high-pressure water through the energy storage tank 6 into the bottom water outlet of the water circuit controller 3, triggering the water circuit controller 3 to open instantly. At this time, the second flushing port of the water circuit controller 3 is opened, but the three high-pressure nozzles 10 have no water to clean the toilet; the interface valve drain port of the water circuit controller 3 is also opened, and the high-pressure water inside the interface valve 7 is released into the flow cavity 8 through the interface valve drain port of the water circuit controller 3, and the interface valve 7 flaps open.

[0140] During this process, the delay process of the water circuit controller 3 is the same as that of the normal water and electricity, but the interface valve 7 will not be closed due to the lack of high-pressure water, and will remain open, and the toilet can drain sewage normally until the high-pressure water is restored and the system returns to normal.

[0141] The cleaning process of feces cleaning is: because the interface valve 7 remains open, the flow chamber 8 cannot maintain negative pressure, and the startup of the negative pressure fan assembly 14 is invalid. It can only be done manually like urine cleaning when the water is cut off.

[0142] This embodiment adopts a mechanical and electrical hybrid control method. The electrical control part can drive the mechanical control part, while the mechanical control part cannot drive the electrical control part. The mechanical control part is used for urinal flushing and is driven by the button water valve 1. The electrical control part is used for toilet flushing and is driven by the electric button 12. The entire intelligent sewage discharge device has the following advantages compared with the vacuum sewage system in the prior art: First, considering that urination occurs more frequently than defecation, the mechanical control part controls urinal flushing, eliminating the frequent startup of electrical appliances and saving energy. Second, considering that urine is easy to clean, the mechanical control part can use very little water to flush urine, saving a large amount of water resources. Third, toilet flushing is driven by the electric button 12 to activate the negative pressure fan assembly, using negative pressure sewage discharge. Using negative pressure also saves a large amount of water when flushing feces, and there is no need to use a large amount of water to flush feces. At this time, a small amount of high-pressure water from the mechanical control part is completely sufficient to handle the toilet flushing. Fourth, when the system is powered on and water is supplied, it is a vacuum toilet, and when there is no water and no power, the system can be used as an ordinary toilet. The entire system ensures that the toilet can still be used regardless of the state.

[0143] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0144] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
