An intelligent sewage discharge device

Abstract

A smart sewage drainage device includes a toilet unit, a mechanical control unit, and an electrical control unit. During urination, the mechanical control unit can control the corresponding water circuit timing to clean the corresponding parts of the toilet unit. During defecation, the electrical control unit and the mechanical control unit work together to create negative pressure in the toilet unit to suck out waste while controlling the corresponding water circuit timing to clean the corresponding parts of the toilet unit. The entire smart sewage drainage device uses negative pressure sewage drainage, eliminating the need for a vacuum pump, reducing costs and noise. The interface valve is closed when there is pressurized water and opens when there is no pressurized water. This allows the interface valve to automatically open in the event of a water outage, allowing the toilet to function normally. At the same time, it can also be applied to traditional flush toilet scenarios in existing home environments, expanding its scope of use.

Description

Technical Field

[0001] The present invention belongs to the technical field of bathroom equipment, and in particular relates to 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 used as common bathroom equipment for handling urine and feces. Common toilets on the market usually use flushing to handle urine and feces and other wastes. However, as water resources become increasingly precious or in some situations where it is inconvenient to use large amounts of water for flushing, traditional toilets are becoming less and less applicable.

[0003] To reduce water waste or to accommodate toilets where flushing with large amounts of water is inconvenient, vacuum drainage technology has become widely used. It's widely used in high-end shopping malls, upscale hotels, high-end public toilets, and rural sewage systems. Urine and feces can be drained through vacuum toilets; household graywater can be drained from the graywater collection point through vacuum pipes; and rural outdoor graywater can also be drained through vacuum pipes. During operation, a vacuum pump creates a vacuum throughout the system. Each toilet in the system must be isolated from the vacuum system by an interface valve. One side of the interface valve is the system vacuum, while the other side is the toilet's normal pressure. When the toilet is flushed, the interface valve opens, and the pressure difference between the system's negative pressure and atmospheric pressure removes the contents of the toilet.

[0004] In the existing technology, on the one hand, the vacuum interface valves in the above-mentioned traditional vacuum sewage drainage systems all use negative pressure as a power source, requiring a vacuum pump, and the negative pressure is used to assist the sealing of the interface valve. In the event of a power outage, the vacuum interface valve cannot be opened and the vacuum sewage drainage system cannot be used normally. The vacuum pump is expensive and noisy. On the other hand, the vacuum sewage drainage system currently on the market is incompatible with traditional flush toilet systems and cannot be used in scenarios with abundant water resources. Summary of the Invention

[0005] The purpose of the present invention is to address the defects of the above-mentioned existing vacuum sewage drainage system and provide an intelligent sewage drainage device that uses high-pressure fluid such as tap water as a power drive, without the need for a vacuum pump to create a vacuum. In the event of a water or power outage, the intelligent sewage drainage device can still be used normally. The entire sewage drainage device saves product costs and water resources, reduces noise, and can be used under both negative pressure and normal pressure conditions, and has a wide range of applications.

The water valve housing 1-7 is provided with a pressure water inlet 1-702 and a water outlet 1-703. The pressure water inlet 1-702 is kept in equilibrium with the pressure-balancing chamber 1-7a and the pressure-charging chamber 1-7b. The water outlet 1-702 is kept in equilibrium with the pressure-releasing chamber 1-7c. The iron core component 1-b1 can be used to connect the pressure-releasing chamber 1-7a and the pressure-releasing chamber 1-7c on the switch actuator 1-b2. The hole 1-I is closed or opened. To put it more simply, the iron core assembly 1-b1 includes an iron core shell 1-b101, one end of the iron core shell 1-b101 is fixed in the water valve shell 1-7, and the other end extends into the inner cavity of the button shell 1-1 and is located in the guide groove in the button 1-2. The iron core shell 1-b101 contains an iron core 1-b102, one end of the iron core 1-b102 is connected to an iron core reset piece 2 1-b103 and corresponds to the permanent magnet 1-3, and the other end is equipped with a silicone 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 shell 1-b101 under the action of the permanent magnet 1-3 and the iron core reset piece 2 1-b103, and the silicone head 1-b104 can close or open the pressure relief hole 1-I as the iron core 1-b102 moves. In this embodiment, the switch execution component 1-b2 is a diaphragm component, and the pressure water inlet maintains constant communication with the pressure-balancing chamber 1-7a through the upper pressure hole 1-III on the diaphragm component. The pressure relief hole 1-I and the upper pressure hole 1-III are arranged on the diaphragm disk 1-b202. The aperture of the upper pressure hole 1-III is smaller than that of the pressure relief hole 1-I, which can ensure that a pressure difference is formed between the pressure-balancing 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 pore. In the original state: as shown in the attached Figure 7bAs shown, the silicone head 1-b104 seals the pressure relief hole 1-I. After the pressurized water enters through the pressure water inlet 1-702, it fills the pressure charging chamber 1-7b. At the same time, the pressurized water enters the pressure equalizing chamber 1-7a through the upper pressure hole 1-III. At this time, because the pressure-bearing area of ​​the pressure equalizing chamber 1-7a is larger than that of the pressure charging chamber 1-7b, and the water pressures of both chambers are the same, the pressure in the pressure equalizing chamber 1-7a is greater than that of the pressure charging chamber 1-7b, and the diaphragm 1-b201 remains in its original state. The pressure charging chamber 1-7b and the pressure relief chamber 1-7c are isolated by the diaphragm 1-b201.

[0113] 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 2 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 in a pressurized state. 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 disk 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.

[0114] 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 2 1-b103, the iron core 1-b102 moves down to seal the pressure relief hole 1-I, and the pressurized 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 again greater than the pressure of the pressure charging chamber 1-7b, and the diaphragm 1-b201 drives the diaphragm disk 1-b202 to move down and return to the original state. 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.

[0115] As attached Figure 3aAs shown in Figures 3b and 3c, the execution unit includes a water circuit controller 3, an interface valve 7, a power adapter 16, a battery 15, a flow cavity 8, a power supply mounting box 31, a water pump 4, a sealing cover 32, a circuit board 13, an energy storage tank 6, a circuit board mounting 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 mounting box 33 and sealed with a sealing cover 32 to prevent moisture. The power adapter 16 and the battery 15 are placed in the power supply mounting box 31. The sewage inlet 7a of the interface valve 7 is connected to the sewage outlet 18a03 of the toilet liner 18a at its upper flange 701a via screws and nuts 35. A suction seal 36 is installed at the interface connection to prevent air or water leakage from the sewage inlet 7a. The sewage outlet 7b of the interface valve 7 is fitted with a discharge seal 37. The sewage outlet 7b of the interface valve 7, fitted with the discharge seal 37, is inserted into the interface valve discharge port on the flow chamber 8. The water pump 4 is secured to the bottom plate of the flow chamber 8 with screws 38. The water circuit controller 3 is mounted on the water circuit controller mounting rail on the outer surface of the flow chamber 8. The negative pressure water valve bracket 34 is fixed to the stepped side of the flow chamber 8 outer shell with bracket screws 39. The negative pressure water valve 2 is fixed to the negative pressure water valve bracket 34 with negative pressure water valve screws 40. The energy storage tank 6 can be installed in a flexible position, and its mounting port is provided with a rigid pipe for connecting to the corresponding pipeline.

[0116] Among them, as attached Figure 9a, 9b, 9c, the water circuit controller 3 includes a water circuit controller shell 3-1, the inner cavity of the water circuit controller shell is divided into a plurality of chambers, the plurality of chambers 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, a normal pressure chamber 3-h and a stamping start chamber 3-i, and the interface valve stamping chamber 3-a and the interface valve pressure relief chamber 3-b are connected by a first passage 3-I The interface valve's stamping chamber 3-a and first flushing opening and closing chamber 3-c are connected via a second passage 3-II. The first flushing opening and closing chamber 3-c and first flushing chamber 3-d are connected via a third passage 3-III. The first flushing opening and closing chamber 3-c and pressure water opening and closing chamber 3-e are connected via a fourth passage 3-IV. The pressure water opening and closing chamber 3-e and pressure water chamber 3-f are connected via a fifth passage 3-V. The pressure water chamber 3-f and second flushing opening and closing chamber 3-g are connected via a sixth passage 3-VI. A diaphragm assembly 3-j separates the space within the inner cavity of the waterway controller housing 3-1, below the second flushing opening and closing chamber 3-g, into a normal pressure chamber 3-h and a stamping activation chamber 3-i. Specifically, in this embodiment, the second passage 3-II and fourth passage 3-IV remain normally open. An interface valve connection port 3-101 is provided on the water circuit controller housing 3-1 at a position corresponding to the interface valve stamping chamber 3-a for connecting the interface valve, an interface valve drain port 3-102 is provided on the water circuit controller housing 3-1 at a position corresponding to the interface valve pressure relief chamber 3-b, a first flushing port 3-103 is provided on the water circuit controller housing 3-1 at a position corresponding to the first flushing chamber 3-d, a pressure water port 3-104 and a pressure water distribution port 3-105 are respectively provided on the water circuit controller housing 3-1 at positions corresponding to the pressure water chamber 3-f, a second flushing port 3-106 is provided on the water circuit controller housing 3-1 at a position corresponding to the second flushing opening and closing chamber 3-g, and a pressurizing water port 3-107 and a pressure relief water port 3-108 are respectively provided on the water circuit controller housing 3-1 at positions corresponding to the stamping start chamber 3-i. A normal pressure port 3-109 is provided on the waterway controller housing 3-1 at a location corresponding to the normal pressure chamber 3-h. A first shaft seal assembly 3-2 is provided in the first passage 3-I, connected to a first return spring 3-3. A second shaft seal assembly 3-4 is provided in the third passage 3-III, connected to a second return spring 3-5. Shaft seal pair assemblies 3-6 are provided in the fifth and sixth passages 3-V and 3-VI, respectively.Specifically, in this embodiment, one end of the water circuit controller main shaft 3-7 is connected to the diaphragm assembly 3-j, and the other end is connected to a return spring 3-8. The water circuit controller main shaft 3-7 can move back and forth in the inner cavity 3-1 of the water circuit controller housing under the action of the diaphragm assembly 3-j and the return spring 3-8. Specifically, in this embodiment, the diaphragm assembly 3-j includes a diaphragm 3-j01. The normal pressure chamber h and the stamping start chamber 3-i are separated by the diaphragm 3-j01. The diaphragm gasket 3-j02 is placed on the diaphragm 3-j01 and moves synchronously with the diaphragm 3-j01. One end of the water circuit controller main shaft 3-7 is inserted into the diaphragm gasket 3-j02. This structure can ensure the pressure difference between the normal pressure chamber 3-h and the stamping start chamber 3-i. In order to increase the airtightness, the water circuit controller 3-7 is equipped with a controller sealing ring at the corresponding connection.

[0117] In original state, if attached Figure 9d As shown, the pressure water inlet 3-104 feeds pressurized water, the pressure water outlet 3-105 feeds other water outlets, the interface valve connection port 3-101 connects to the interface valve, the button connects to the pressure water inlet 3-107, and the pressure relief water inlet 3-108 connects to the flow control valve. At this point, the first passage 3-I is sealed by the first shaft seal assembly 3-2, isolating the interface valve pressure chamber 3-a from the interface valve pressure relief chamber 3-b. The third passage 3-III is sealed by the second shaft seal assembly 3-4, isolating the first flushing opening and closing chamber 3-c from the first flushing chamber 3-d. The fifth passage 3-V is open. The sixth passage 3-VI is sealed by one end of the shaft seal pair assembly 3-6, isolating the pressure water chamber 3-f from the second flushing opening and closing chamber 3-g. The second passage 3-II and the fourth passage 3-IV are normally open. The pressure water tank 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.

[0118] When fully opened, Figure 9e As shown, the moment the button is pressed, pressurized water enters the pressurized start chamber 3-i. The shaft seal retaining rings 2 (3-11) at various locations on the waterway controller main shaft move upward along with the waterway controller main shaft 3-7 until they reach the bottom. 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 successively opened, and the fifth passage 3-V is sealed by one end of the shaft seal pair assembly 3-6. At this point, water within the interface valve flows through the first passage 3-I to the interface valve pressure relief chamber 3-b and out through the interface valve drain port 3-102, opening the interface valve. The pressurized water then flows through the sixth passage 3-VI to the second flush opening and closing chamber 3-g and out through the second flush port 3-106, completing the flushing process of the second flush port 3-106.

[0119] When the delayed recovery state is in progress: Figure 9f As shown, by pressing the button, the external pressurized water is isolated from the pressurized starting chamber 3-i. The pressurized water inside the pressurized starting chamber 3-i slowly flows out through the capillary action of the pressure relief port 3-108. The water circuit controller main shaft 3-7 moves downward under the action of the return spring 1 3-8. The second shaft seal retaining ring 3-11 at various locations on the water circuit controller main shaft 3-7 slowly moves downward along with the water circuit controller main shaft 7. At this point, the first shaft seal assembly 3-2 seals the first passage 3-1, isolating the interface valve pressure chamber 3-a from the interface valve pressure relief chamber 3-b, and preventing further discharge of water from the interface valve.

[0120] Continue delayed recovery: as attached Figure 9g As shown, the second shaft seal retaining ring 3-11 at various locations on the main shaft of the waterway controller continues to move downward. Due to the different distances between the second shaft seal retaining ring 3-11 and the corresponding shaft seal assembly, the movable shaft seal in the fifth passage 3-V opens, and the pressure water opening and closing chamber 3-e communicates with the pressure water tank 3-f. The pressure water opening and closing chamber 3-e then 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 tank 3-d, and pressurized water flows out through the first flushing port 3-103, completing the flushing process of the first flushing port 3-103. The pressure water tank 3-f and the second flushing opening and closing chamber 3-g are closed by the other side of the shaft seal pair assembly 3-6, preventing the pressure water from flowing to the second flushing opening and closing chamber 3-g via the sixth passage 3-VI, and the pressure water stops flowing out of the second flushing port 3-106.

[0121] Restore to original state: as attached Figure 9h As shown, the second shaft seal retaining ring 3-11 continues to move downward 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. Pressurized water cannot flow through the third passage 3-III to the first flushing opening and closing chamber 3-c. The pressurized water stops flowing out of the first flushing port 3-103. Pressurized water can only flow through the fifth passage 3-V, the fourth passage 3-IV, and the second passage 3-II to the interface valve stamping chamber 3-a. Pressurized water flows through the interface valve connection port 3-101 to the interface valve, closing the interface valve.

[0122] As attached Figure 8a and 8bAs shown, the interface valve 7 includes a drive unit 7-a and a sewage discharge unit 7-b. The drive unit 7-a can link the opening and closing of the sewage inlet of the sewage discharge unit 7-b through a linkage mechanism 7-c. The drive unit 7-a includes a drive housing 7-1. The diaphragm assembly 7-2 divides the inner cavity of the drive 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 drive housing 7-1. The upper chamber 7-101 is connected to the outside world through a water source interface 7-103. A reset member 7-3 is provided in the lower chamber 7-102 to provide a reset force for the diaphragm assembly 7-2 to move upward. More specifically, the diaphragm assembly 7-2 is fixedly connected to one end of the interface valve main shaft 7-4 in the linkage mechanism 7-c. The diaphragm assembly 7-2 includes a diaphragm 7-201, which 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 attached figure, 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 and is hingedly connected to the lever 7-7. The lever 7-7 is provided with a rotating shaft 7-10 at one end. The rotating shaft 7-10 is mounted in a groove 7-901 on the sewage discharge housing 7-9 and can rotate. Preferably, the rotating shaft 7-10 is mounted in the groove 7-901 on the sewage discharge housing 7-9 so as to be only rotatable. The other end of the lever 7-7 is provided with a roller 7-11, on which a roller 7-12 is mounted. The roller 7-11 is mounted in the chute 7-801 on both sides of the back of the flap 7-8. The roller 7-11 can roll in the chute 7-801, and the roller 7-12 can roll between the chute 7-801 on both sides of the back of the flap 7-8. The bottom of the portion between the chute 7-801 on both sides of the back of the flap 7-8 is provided with an arcuate surface 7-802 that matches the shape of the roller 7-12. A second rotating shaft 7-13 is provided on one side of the flap 7-8. The second rotating shaft 7-13 is mounted in the second groove 7-902 on the sewage discharge housing 7-9 and can rotate. In this embodiment, the second rotating shaft 7-13 is preferably only able to rotate when mounted 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. This port 7-104 is used to communicate with the outside world and, when needed, can also be connected to an external air pump to provide high-pressure airflow. 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 a seal between the drive housing 7-1 and the sewage discharge housing 7-9. A linear bearing 7-15 is installed on the interface valve main shaft 7-4 located within the drive housing 7-1. Specifically, the other end of the interface valve spindle 7-4 is connected to the lever 7-7 via a pin 7-26, forming a hinged connection. The pin 7-26 passes through a waist-shaped hole 7-701 provided on the lever 7-7. The shape of the waist-shaped hole 7-701 corresponds to the motion trajectory of the hinge point of the interface valve spindle and the lever during the movement of the lever 7-7, thereby ensuring that the interface valve spindle and the lever 7-7 do not become stuck, or that the flap 7-8 fails to seal the sewage outlet 7-904. The front of the flap 7-8 is fixed with a clip 7-30 via a self-tapping screw 7-29. A sealing 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 housing 7-9 is closed.

[0123] As attached Figure 8bAs shown, when the interface valve is in its original state, that is, when the interface valve is open, high-pressure water (such as tap water) is introduced through the water source interface 7-103, and the upper chamber 7-101 on the upper part of the diaphragm 7-201 is filled with high pressure, and the lower chamber 7-102 on the lower part of the diaphragm 7-201 is connected to the outside world (atmosphere or low pressure) through the gas port 7-104, so that the pressure on the upper part of the diaphragm 7-201 is much higher than the pressure on the lower part, thereby compressing the reset member 7-3, causing the diaphragm cover 7-202 to move downward; the interface valve main shaft 7-4 connected to the diaphragm cover 7-202 moves downward at the same time, and the other end of the interface valve main shaft 7-4 tightly presses the lever 7-7, causing the lever 7-7 to rotate downward around the rotating shaft 1 7-10, and the roller 7-12 at the other end of the lever 7-7 slides while rolling on the back of the flap 7-8, causing the flap 7-8 to rotate downward around the rotating shaft 2 7-13, thereby tightly covering the sewage inlet, so that the sewage inlet is isolated from the sewage outlet.

[0124] As attached Figure 8e As shown, when the interface valve is in the activated state, i.e., when the interface valve is in the open state, high-pressure water (e.g., tap water) is released through the water source interface, and the reset member 7-3 immediately moves upward against the diaphragm cover 7-202. The diaphragm cover 7-202 pulls the interface valve main shaft 7-4 upward, and the interface valve main shaft 7-4 pulls the lever 7-7 upward about the first axis 7-10. The roller 7-11 at the other end of the lever 7-7 slides within the chute 7-801 on the back of the flap 7-8. The roller 7-11, through the chute 7-801, causes the flap 7-8 to rotate upward about the second axis 7-13, thereby opening the sewage inlet and connecting the sewage inlet with the sewage outlet. In this embodiment, the connection of the interface valve is equipped with a metal gasket according to actual conditions to enhance the sealing and reliability of the product.

[0125] As attached Figure 10aAs shown in Figures 10b and 10c, the negative pressure water valve 2 includes a water valve body unit 2-a, which 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 of the slider 2-2 and the edge of the mouth of the pneumatic unit housing 2-1, thereby sealing 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 water valve body unit 2-a to open. The pneumatic unit housing 2-1 is connected to the external vacuum system through a capillary check valve 2-5. The magnet 2-4 is connected to a reset spring 2-14 to provide it with a reset force for upward movement. The capillary check valve 2-5 includes a check rubber cover 2-501, which is mounted on the side of the pneumatic unit housing 2-1. A negative pressure hole 2-501a is provided on the check rubber cover 2-501. An air flow hole 2-102 is provided on the pneumatic unit housing 2-1 at a position 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. The check rubber 2-502 is inserted into the mounting groove of the check rubber cover 2-501 and is located at a corresponding position on the outside of the air flow hole 2-102. The capillary plug 2-503 is mounted in the mounting groove of the check rubber cover 2-501 and is located at a corresponding position on the outside of the air hole on the check rubber 2-502.

[0126] As attached Figure 10b As shown, the water valve body unit 2-a includes a water valve body valve housing 2-6, the lower end of the sealing knob 2-7 is fixedly mounted on the water valve body valve housing 2-6 to form a water valve body shell, the upper end of the sealing knob 2-7 extends into the guide hole 2-201 on the slider 2-2, and the sealing knob 2-7 is equipped with a water valve core 2-8. The water valve core 2-8 can move up and down in the inner cavity of the sealing knob 2-7, and the water valve core spring 2 is connected to the water valve core 2-8 for auxiliary compression. -9, a pilot hole sealing head 2-10 is mounted on the bottom of the water valve core 2-8, and the pilot hole sealing head 2-10 corresponds to the pilot hole 2-1201 of the water valve sealing cover 2-12 in the inner cavity of the water valve body valve housing 2-6. When the water valve core 2-8 moves up and down in the inner cavity of the sealing knob 2-7, the pilot hole sealing head 2-10 can seal or unseal the pilot hole 2-1201 of the water valve sealing cover 2-12 in the inner cavity of the water valve body valve housing 2-6.

[0127] 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. The gasket 2-17 is fitted over 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. These undercuts are clipped onto the water valve body housing 2-6 to securely mount the pneumatic unit housing 2-1 and the water valve body housing 2-11.

[0128] The operation process of this 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 pressurized water is connected, the pressurized 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, the upper water pressure disappears instantly, and 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 becomes open. 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.

[0129] As attached Figure 12aAs shown in Figures 12b and 12c, the negative pressure fan assembly 14 includes a high-pressure fan 14a, a fan elbow 14b, a fan fixed link ring 14c, a fan suction end connector 14d, a suction end silencer 14e, an exhaust end silencer 14f, and an exhaust end outer tube 14g. Specifically, the high-pressure fan 14a is placed in an internal space formed by the combination of the fan elbow 14b and the fan fixed link ring 14c.

One end of the flip cover discharge valve assembly 8b is connected to the excrement discharge port on the negative pressure chamber assembly 8a. An inner chamber is provided in the negative pressure chamber assembly 8a. The high-pressure blower 14a can extract air from the inner chamber through the air intake of the negative pressure blower assembly on the negative pressure chamber assembly 8a and discharge the air through the corresponding exhaust channel on the negative pressure chamber assembly 8a through the air outlet of the negative pressure blower assembly on the negative pressure chamber assembly 8a, thereby forming a negative pressure air duct in the inner chamber.

[0131] As attached Figure 13aAs shown in Figures 13b and 13c, the negative pressure chamber assembly 8a includes a negative pressure chamber upper cover 8a01 and a negative pressure chamber lower shell 8a02.

This intercepts and blocks humid air molecules flowing through the air duct inside the cavity as they pass through these ribs. They eventually accumulate and fall to the bottom of the cavity, preventing moisture from entering the fan and affecting its service life. The negative pressure chamber cover 8a01 is provided with four cavity windshield screw fixing holes 8a01f. The cavity windshield 8a03 is mounted and fixed thereto using self-tapping screws 8a05.

After the excrement is sucked into the cavity, it slides out to the excrement discharge outlet through the inclined slide under the action of gravity; the water retaining rib 8a02g can be used to splash water in the cavity. The inner cavity bottom plate 8a02b of the negative pressure chamber lower shell 8a02b is provided with a slope 8a02b01 to ensure that the dirt is retained at the bottom of the cavity and can be discharged even when there is a large water flow. The inner cavity bottom plate 8a02b of the negative pressure chamber lower shell 8a02b is provided with anchor bolts 8a10 for ground installation. The bottom edge of the negative pressure chamber lower shell 8a02b is provided with a number of circular magnets 22 with holes for attracting a number of iron screws 21 on the toilet shell 18c. The shape of the negative pressure chamber lower shell 8a02b matches the toilet shell 18c.

[0135] As attached Figure 16aAs shown in Figures 16b, 16c, 16d, 16e, and 16f, the flip-cover drain valve assembly 8b includes a drain valve connecting pipe 8b01. An exhaust channel 8b01a and a sewage channel 8b01b are provided within the drain valve connecting pipe 8b01. The flip cover 8b02 can open or close the sewage channel 8b01b under the action of an external force and a magnet group. The exhaust channel 8b01a communicates with the corresponding exhaust channel on the negative pressure chamber assembly 8a and is isolated from the sewage channel 8b01b. The corresponding exhaust channel refers to the channel connected to the exhaust port 8a02d of the negative pressure blower assembly.

[0136] It should be noted that the installation position and structure of the various components in the above-mentioned intelligent sewage discharge device are only a specific embodiment of the present invention, and does not mean that the present invention can only adopt the structure described in the above embodiment to achieve the purpose of the present invention. Generally speaking, there will always be a specific structure 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 based on the inspiration of the technical solution of the present invention fall within the scope of protection of the present invention.

[0137] The operation process of the intelligent sewage discharge device provided in this embodiment is:

[0138] In the original state (i.e., before sewage discharge begins), the water outlet of the water pump 4 is divided into two parts: one part is supplied to the water circuit controller 3 for toilet flushing, 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 circuit controller 3. The advantages of dividing the water outlet of the water pump 4 into two parts are: first, the amount of water used for toilet flushing is much greater than the amount of water used to trigger the water circuit controller 3. When the toilet is flushed, the high-pressure water used to trigger the water circuit controller 3 can be guaranteed not to lose pressure, ensuring that the water circuit controller 3 can be opened normally; second, when the water supply is cut off at home, the energy storage tank 6 has a reserve of high-pressure water, which can trigger the water circuit controller 3 to open, thereby releasing the high-pressure water inside the interface valve 7 through the water circuit controller 3, causing the interface valve 7 to open and the toilet to continue to function normally.

[0139] In its initial 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 circuit controller 3. The water inlets of the button water valve 1 and the negative pressure water valve 2 are connected to the high-pressure water and are on standby. The battery 15 powers the components. Even in a power outage, the toilet can generally flush 300 times normally. The power adapter charges the battery. The negative pressure blower assembly 14 is not operating and is in standby mode. There is no negative pressure in the negative pressure chamber assembly 8a. The flap 8b02 of the flap drain valve assembly 8b is closed and sealed due to the suction force of the magnet. The flap of the anti-backflow floor drain 8a09 is also closed, and the air duct is sealed. The flap of the interface valve 7 is also closed, preventing sewer odors from entering the toilet.

[0140] When the water and electricity are in normal condition and urine needs to be cleaned: press the button water valve 1, the outlet of the button water valve 1 instantly releases high-pressure water into the water circuit control 3 through the energy storage tank 6, triggering the water circuit controller 3 to open instantly. At this time, the second flush port of the water circuit controller 3 is flowing with water, and the three high-pressure nozzles 10 have started to spray 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 is opened. Release the button water valve 1, the high-pressure water at the outlet of the button water valve 1 is disconnected, and another interface at the bottom of the water circuit controller 3 is connected to the throttle valve 11. The high-pressure water filled in the cavity at the bottom of the water circuit controller 3 is slowly released through the throttle valve 11. This time is called the delay process. During the delay process, the water circuit controller 3 slowly recovers.

[0141] During the above process, the waterway of the intelligent sewage system undergoes the following changes:

[0142] The second flushing port of the water circuit controller 3 is opened, and the three high-pressure nozzles 10 start spraying water; the water outlet of the interface valve of the water circuit controller 3 is opened, and the high-pressure water inside the interface valve 7 is released through the water outlet of the interface valve of the water circuit controller 3, and the flap of the interface valve 3 is opened;

[0143] The drain port of the interface valve of the water circuit controller 3 is closed, and the drain outlet of the interface valve 7 is locked;

[0144] The second flushing port of the water circuit controller 3 is opened to water, and the three high-pressure nozzles 10 spray water to flush the inner surface of the toilet;

[0145] The second flushing port of the water circuit controller 3 is disconnected, the first flushing port is open to water, and the bottom interface of the toilet tank is open to water to flush the bottom of the toilet tank;

[0146] The first flushing port of the water circuit controller 3 is disconnected, and water is no longer sprayed from the bottom of the toilet tank. The high-pressure water has to pass through the charging interface valve 7 of the water circuit controller 3. The interface valve 7 is closed again, and the system returns to its initial state.

[0147] When the water and electricity are working properly and you need to clean the stool, you press the electric button 12, and the negative pressure blower assembly 14 starts up quickly. The high-speed rotation of the high-pressure blower draws the air in the negative pressure chamber assembly 14 into the blower's exhaust port. Under the action of the wind pressure, the flap of the anti-backflow floor drain 8a09 opens, allowing air to pass through it and into the air duct at the bottom of the chamber. Finally, the air enters the sewer through the exhaust channel of the flap drain valve assembly 8b. This quickly fills the toilet flow chamber 8 with negative pressure.

[0148] The negative pressure port of the negative pressure water valve 2 is connected to the flow cavity 8. Under the action of 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 water circuit controller 3, and the water circuit controller 3 opens;

[0149] The second flush port of the water circuit controller 3 is opened, and the three high-pressure nozzles 10 begin to spray water; the water outlet of the interface valve of the water circuit controller 3 is opened, and the high-pressure water inside the interface valve 7 is released through the water circuit controller 3. The interface valve 7 flap opens. At the moment of opening, accompanied by negative pressure, the waste in the toilet is quickly sucked away and discharged through the internal household sewage pipe connected to the flow chamber 8;

[0150] The negative pressure fan assembly 14 stops;

[0151] The drain port of the interface valve of the water circuit controller 3 is closed, and the drain outlet of the interface valve 7 is locked;

[0152] The second flushing port of the water circuit controller 3 is opened to water, and the three high-pressure nozzles 10 spray water to flush the inner surface of the toilet tank;

[0153] The second flush port of the water circuit controller 3 is disconnected, the first flush port is open to water, and the bottom interface of the toilet is open to water to flush the bottom of the toilet tank;

[0154] The first flushing port of the water circuit controller 3 is disconnected, and water is no longer sprayed from the bottom of the toilet tank. The high-pressure water can only be filled into the interface valve 7 through the water circuit controller 3. The interface valve 7 is closed again, and the system returns to its initial state.

[0155] When draining, the flap in the flap drain assembly 8b opens, and after draining, it closes automatically under the action of magnetic attraction.

[0156] It should be noted that when household tap water pressure is extremely low, water pump 4 can be used to increase the pressure. A flow meter is located within the outlet of water pump 4. Specifically, when the second flush port of water circuit controller 3 is opened and the three high-pressure nozzles 10 begin spraying water, the flow meter detects the tap water flow rate. If the flow rate is extremely low, water pump 4 starts to automatically increase the tap water pressure. If the flow rate is sufficient, water pump 4 remains on standby and does not start.

[0157] When the power is cut off but the water supply is not cut off, the internal battery 15 can be used for the system during the power outage.

[0158] When there is a power outage and water shortage: during the urine cleaning process, there is still high-pressure water inside the energy storage tank 6. Press the button water valve 1, 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 flips open.

[0159] During this process, the delay process of the water circuit controller 3 is the same as that of the normal water and electricity conditions, but the interface valve 7 will not close due to the lack of high-pressure water and will remain open, allowing the toilet to drain normally until the high-pressure water is restored and the system returns to normal.

[0160] The cleaning process of feces cleaning is: since the interface valve 7 remains open, the flow chamber 8 cannot maintain negative pressure, and the startup of the negative pressure fan component 14 is invalid. It can only be done manually by flushing water when the water is cut off, just like urine cleaning.

[0161] This embodiment adopts a hybrid mechanical and electrical control method. The electrical control part can drive the mechanical control part, but the mechanical control part cannot drive the electrical control part. The mechanical control part is used for urination flushing and is driven by the button water valve 1; the electrical control part is used for defecation flushing and is driven by the electric button 12. The entire intelligent sewage discharge device has the following advantages over the vacuum sewage discharge system in the prior art: First, considering that urination is more frequent than defecation, the mechanical control part controls urine flushing, eliminating the need for frequent electrical startup 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 lot of water; third, defecation flushing is driven by the electric button 12, which turns on the negative pressure fan assembly and utilizes negative pressure sewage discharge. The use of negative pressure also saves a lot of water when flushing defecation, eliminating the need to use a large amount of water to flush defecation. At this time, the small amount of high-pressure water from the mechanical control part is completely sufficient to cope with the flushing of the toilet. Fourth, when there is electricity and water, the system is a vacuum toilet. When there is no water and electricity, the system can be used as an ordinary toilet. The entire system ensures that the toilet can be used regardless of its state.

[0162] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0163] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
