Description

Technical Field

[0001] This application relates to the field of marine sanitary equipment technology, and in particular to a defecation system and a ship. Background Technology

[0002] Sanitary products used on ships, such as toilets and urinals, typically employ gravity-fed piped collection systems. A water tank is installed above the toilet bowl, and the combined force of water flow and gravity flushes waste away from the bowl through a drain pipe.

[0003] However, each flush after using the toilet requires emptying the tank completely, and subsequent flushes require waiting for the tank to refill; otherwise, the water volume and gravitational potential energy are insufficient to flush away the waste, resulting in high water consumption. Furthermore, to ensure successful flushing, the pipes need to be large in diameter and angled, increasing the difficulty of laying pipes within the ship's hull. Summary of the Invention

[0004] The purpose of this invention is to provide a defecation system and a ship that can solve the problem of the difficulty in arranging a defecation system in the hull in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] Firstly, a defecation system is provided, comprising:

[0007] The toilet bowl has a drain pipe connected to its bottom.

[0008] A flushing assembly includes a connected water valve and a flushing ring pipe. The flushing ring pipe is located at the opening of the toilet bowl and has a through hole. The water valve can allow or block water from entering the flushing ring pipe.

[0009] The discharge assembly includes a housing, two elastic valves, and two telescopic modules. The housing has a connecting cavity that communicates with the discharge pipe. The two elastic valves are symmetrically arranged in the connecting cavity, dividing the connecting cavity into a discharge chamber and two actuating chambers respectively located on both sides of the discharge chamber. The two actuating chambers are respectively connected to the telescopic modules. The telescopic modules can drive the two elastic valves to move closer or further apart to open and close the discharge chamber. When the discharge chamber is closed, the water in the discharge pipe is blocked by the elastic valves to form a water seal.

[0010] A distance sensor is disposed on the two elastic valves and is capable of acquiring the distance between the two elastic valves;

[0011] The controller is communicatively connected to the water valve, the telescopic module, and the distance sensor.

[0012] The vacuum suction assembly includes a vacuum tube and a vacuum pump that is communicatively connected to the controller. The vacuum pump is connected to the defecation chamber through the vacuum tube. The vacuum pump can draw suction from the vacuum tube to create a negative pressure, so that the waste in the toilet bowl can be drawn into the vacuum tube along with the water flow.

[0013] As a preferred option for the defecation system, it also includes:

[0014] A timer, communicatively connected to the controller, is used to time the opening time of the water valve and the action time of the telescopic module.

[0015] As a preferred option for the defecation system, it also includes:

[0016] A pressure sensor is installed in the vacuum tube and is communicatively connected to the controller. The pressure sensor is capable of detecting the air pressure in the vacuum tube.

[0017] As a preferred embodiment of the defecation system, the telescopic module includes an air pump and an air tube. The air pump is connected to the actuation chamber through the air tube. When the air pump draws air into the actuation chamber or inflates the actuation chamber, it can drive the two elastic valves to move closer or further apart.

[0018] As a preferred embodiment of the defecation system, the telescopic module further includes a return spring, the two ends of which abut against the elastic valve and the cavity wall of the actuation chamber, respectively.

[0019] Secondly, a control method for the defecation system is provided, comprising:

[0020] In response to the start signal, the vacuum pump is activated to draw in the vacuum tube, so that the vacuum tube is pre-stressed.

[0021] The sewage discharge cycle includes: opening the water valve of the flushing component to allow water to flow into the toilet bowl through the through hole of the flushing ring pipe, allowing the waste in the toilet bowl to enter the drain pipe; controlling the telescopic module of the discharge component to drive the two elastic valves away from each other to open the discharge chamber, allowing the vacuum tube to suck the waste in the drain pipe through the opened discharge chamber; after the waste leaves the toilet bowl, closing the water valve and controlling the telescopic module to drive the two elastic valves closer to each other, so that the closed discharge chamber blocks water and maintains a water seal at the drain pipe;

[0022] After the sewage discharge cycle is completed, the distance sensor detects the actual distance between the two elastic valves. When the actual distance is greater than or equal to a preset distance, the sewage discharge cycle is entered again.

[0023] As a preferred embodiment of the control method for a defecation system, after the waste leaves the toilet bowl, the water valve is closed and the telescopic module is controlled to drive the two elastic valves closer together, including:

[0024] After the water valve is opened, a timer is used to time the opening time of the water valve;

[0025] When the opening time reaches the first preset time, the water valve is closed;

[0026] After the telescopic module drives the two elastic valves away from each other, the action time of the telescopic module is timed by a timer.

[0027] When the action time reaches the second preset time, the telescopic module is controlled to drive the two elastic valves to move closer to each other.

[0028] As a preferred embodiment of the control method for a defecation system, the step of activating a vacuum pump to draw air from a vacuum tube in response to a start signal includes:

[0029] Obtain the current gas pressure of the vacuum tube detected by the pressure sensor;

[0030] When the current air pressure is greater than the preset air pressure, a start-up message is generated, and in response to the start-up message, the vacuum pump is activated to draw air from the vacuum tube.

[0031] As a preferred embodiment of the control method for the defecation system, the telescopic module of the control discharge component drives two elastic valves away from each other, including:

[0032] The air pump is controlled to draw air from the actuating chamber of the discharge assembly, so that the two elastic valves are moved away from each other;

[0033] The control of the telescopic module to drive the two elastic valves closer together includes:

[0034] The air pump is controlled to inflate the actuation chamber so that the two elastic valves move closer to each other.

[0035] Thirdly, a vessel is provided, including the aforementioned defecation system, which is disposed of in a toilet within the hull of the vessel.

[0036] The beneficial effects of this application are as follows:

[0037] The waste disposal system of this application collects excrement in a latrine and flushes it using a flushing component, causing the excrement in the drain pipe to mix with water to form waste. Then, a discharge component and a vacuum suction component are used to remove the waste from the drain pipe. Compared to existing technologies that rely on the gravitational potential energy of flowing water in a storage tank to flush the latrine and remove excrement, this system is more water-efficient and improves waste disposal efficiency. Furthermore, since it does not rely on the gravitational potential energy of flowing water to flush away excrement, there is no need to arrange the discharge pipe at an angle, allowing for the installation of small-diameter pipes, significantly reducing the difficulty of pipe installation within the ship's hull.

[0038] In addition, by setting up distance sensors and controllers, and communicating with the water valve of the flushing component, the telescopic module of the discharge component, and the vacuum pump of the vacuum suction component, the opening and closing time of the water valve and the vacuum pump, as well as the telescopic movement of the telescopic module, can be precisely controlled. This allows for more precise control of water usage and the opening and closing of the defecation chamber, which can reduce blockage and incomplete closure of the defecation chamber, and also form a water seal to reduce odor and improve the user experience.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0054] To address the challenge of integrating waste disposal systems within the ship's hull in existing technologies, such as... Figure 1 As shown, this embodiment provides a defecation system, including:

[0055] The toilet bowl 1 has a drain pipe 11 connected to its bottom;

[0056] The flushing assembly 2 includes a water valve 21 and a flushing ring pipe 22 connected together. The flushing ring pipe 22 is located at the opening of the toilet bowl 1. A through hole 23 is provided on the flushing ring pipe 22. The water valve 21 can allow or block water from entering the flushing ring pipe 22.

[0057] The discharge assembly 3 includes a housing 31, two elastic valves 32, and two telescopic modules 33. The housing 31 has a connecting cavity 310 that connects to the drain pipe 11. The two elastic valves 32 are symmetrically arranged in the connecting cavity 310, dividing the connecting cavity 310 into a defecation cavity 311 and actuating cavities 312 respectively arranged on both sides of the defecation cavity 311. The two actuating cavities 312 are respectively connected to the telescopic modules 33. The telescopic modules 33 can drive the two elastic valves 32 to move closer or further apart to open and close the defecation cavity 311. When the defecation cavity 311 is closed, the water in the drain pipe 11 is blocked by the elastic valves 32 to form a water seal.

[0058] Distance sensor 41 is mounted on the two elastic valves 32 and is capable of acquiring the distance between the two elastic valves 32;

[0059] Controller 5 communicates with water valve 21, telescopic module 33 and distance sensor 41;

[0060] The vacuum suction assembly 6 includes a vacuum tube 61 and a vacuum pump 62 connected to the communication controller 5. The vacuum pump 62 is connected to the defecation chamber 311 through the vacuum tube 61. The vacuum pump 62 can draw the vacuum tube 61 to form a negative pressure, so that the waste in the toilet bowl 1 can enter the vacuum tube 61 with the water flow.

[0061] This application involves installing a drain pipe 11 connected to the bottom of the toilet bowl 1, and then installing the flushing ring pipe 22 of the flushing assembly 2 at the opening of the toilet bowl 1. After the user urinates or defecates in the toilet bowl 1, the water valve 21 is opened to allow water in the flushing ring pipe 22 to pass through its through hole 23 (e.g., Figure 2 As shown, the water flows into the toilet bowl 1 and flushes the bowl wall, causing water and excrement to form waste that accumulates at the drain pipe 11 at the bottom of the bowl. Simultaneously, a discharge assembly 3 and a vacuum suction assembly 6 are installed to discharge the waste from the drain pipe 11. Once the waste has been completely discharged, the water valve 21 of the flushing assembly 2 is closed to prevent water from the flushing ring pipe 22 from continuing to enter the toilet bowl 1, thus preventing water from overflowing the toilet bowl 1.

[0062] The discharge assembly 3 includes a housing 31, two elastic valves 32, and two telescopic modules 33. The housing 31 has a connecting cavity 310 that connects to the discharge pipe 11. The two elastic valves 32 are symmetrically arranged in the connecting cavity 310. The two elastic valves 32 divide the connecting cavity 310 into a defecation cavity 311 and actuating cavities 312 respectively arranged on both sides of the defecation cavity 311, allowing waste to be discharged through the defecation cavity 311. Each of the two actuating cavities 312 is provided with a telescopic module 33. Under the extension and retraction of the telescopic module 33, the two elastic valves 32 can be driven to move closer or further apart, thereby opening or closing the defecation cavity 311 (e.g., Figure 1 and Figure 3(As shown). In addition, the vacuum adsorption assembly includes a vacuum tube 61 and a vacuum pump 62. Since the vacuum tube 61 is pre-drawn by the vacuum pump 62 to form a negative pressure environment, the opened defecation chamber 311 can be directly connected to the negative pressure vacuum tube 61, so that the vacuum tube 61 can draw out the dirt in the drain pipe 11 through the opened defecation chamber 311.

[0063] It should be noted that after the waste in the drain pipe 11 is sucked out, the clean water in the flushing ring pipe 22 continues to flush the toilet bowl 1 and collects at the drain pipe 11. At this time, the telescopic modules 33 in the two actuating chambers 312 can drive the two elastic valves 32 to move closer to each other. That is, when the defecation chamber 311 is closed, the water in the drain pipe 11 is blocked by the elastic valves 32 to form a water seal, and at the same time, the water valve 21 is closed to prevent too much water in the toilet bowl 1. In this embodiment, the water seal can not only isolate the odor emitted by the waste remaining at the elastic valves 32, but also dissolve and moisten the excrement when the toilet bowl 1 is used again, forming mixed waste in advance, and also reduce the amount of excrement sticking to the toilet bowl 1.

[0064] In addition, distance sensors 41 are respectively installed on the two elastic valves 32 to obtain the distance between the two elastic valves 32. The distance sensors 41, water valve 21, telescopic module 33 and vacuum pump 62 are communicatively connected to controller 5, so that controller 5 can control the opening and closing of water valve 21, the extension and retraction of telescopic module 33 and the suction time of vacuum pump 62 according to the obtained distance between the two elastic valves 32. For example, if the distance between the two elastic valves 32 is too large, the defecation chamber 311 may not be completely closed. The telescopic module 33 can be controlled to continue to drive the two elastic valves 32 to continue to move closer to each other and completely close the defecation chamber 311. If the distance sensor 41 continues to detect that the distance between the two elastic valves 32 is still too large, there may be dirt blockage in the defecation chamber 311. At this time, water valve 21 and vacuum pump 62 are opened first to flush toilet bowl 1 and defecation chamber 311 while vacuuming vacuum tube 61 to form negative pressure. The telescopic module 33 is controlled to drive the two elastic valves 32 away from each other, fully opening the defecation chamber 311. This allows the water flow at the drain pipe 11 to flush the elastic valves 32, thereby removing any remaining and clogged waste from the defecation chamber 311. At this time, the water valve 21 and vacuum pump 62 are closed, and the telescopic module 33 is controlled to drive the two elastic valves 32 closer together. Clean water then gathers again at the drain pipe 11 and is blocked by the closed defecation chamber 311, forming a water seal.

[0065] In summary, the waste disposal system of this application collects excrement in the toilet bowl 1 and flushes it using the flushing assembly 2, causing the excrement in the drain pipe 11 to mix with water to form waste. Then, the waste in the drain pipe 11 is sucked out by the discharge assembly 3 and the vacuum suction assembly 6. Compared to the prior art, which relies on the gravitational potential energy of flowing water in a storage tank to flush the toilet bowl 1 and remove excrement, this system is more water-efficient and improves waste disposal efficiency. Furthermore, since it does not rely on the gravitational potential energy of flowing water to flush away excrement, there is no need to arrange the discharge pipe at an angle, allowing for the installation of small-diameter pipes, greatly reducing the difficulty of pipe installation within the ship's hull.

[0066] In addition, by setting a distance sensor 41 and a controller 5, and communicating the controller 5 with the water valve 21 of the flushing assembly 2, the telescopic module 33 of the discharge assembly 3, and the vacuum pump 62 of the vacuum suction assembly 6, the opening and closing time of the water valve 21 and the vacuum pump 62 can be precisely controlled, as well as the telescopic movement of the telescopic module 33. This further enables precise control of water usage and the opening and closing of the defecation chamber 311, which can reduce blockage and incomplete closure of the defecation chamber 311, and also form a water seal to reduce odor and improve the user experience.

[0067] Specifically, refer to Figure 3 The defecation system also includes a timer 42 connected to the controller 5. The timer 42 can time the opening time of the water valve 21 and the action time of the telescopic module 33, thereby allowing the controller 5 to precisely control the start and stop times of the water valve 21 and the extension and retraction times of the telescopic module 33. For example, by timing the opening time of the water valve 21, the controller 5 can close the water valve 21 when the opening time of the water valve 21 reaches a first preset time, thus timely shutting off the water supply to the flushing ring pipe 22 and preventing water from overflowing the toilet bowl 1. Furthermore, the timing of the extension or retraction of the telescopic module 33 can be controlled in conjunction with the opening and closing of the water valve 21. For example, the water valve 21 can be opened for a certain period of time before the telescopic module 33 is driven to retract, thereby causing the two elastic valves 32 to move away from each other. In other words, the water flow is first mixed with the excrement to form waste before the defecation chamber 311 is opened. This avoids the odor from being released through the drain pipe 11 after the defecation chamber 311 is opened first, and also avoids the water flow from entering the defecation chamber 311 directly without mixing with the excrement and being discharged through the vacuum tube 61. This reduces the direct effect of the vacuum tube 61 on the atmospheric environment and reduces the suction force on the excrement.

[0068] Subsequently, the timer 42 is used to time the extension of the telescopic module 33. When the extension time reaches the second preset time, the telescopic module 33 can be controlled to drive the two elastic valves 32 closer together, thereby closing the defecation chamber 311 in a timely manner. In this embodiment, the water valve 21 can be opened before the defecation chamber 311, and the defecation chamber 311 can be closed before the water valve 21. This ensures that a water seal is provided at the bottom of the toilet bowl 1 when the defecation chamber 311 is opened and closed, further reducing the transmission of odors from the vacuum tube 61 to the toilet bowl 1 through the drain pipe 11.

[0069] Further, refer to Figure 4 A check valve 7 is installed at the drain pipe 11, allowing only waste and water to enter the toilet chamber 311 in one direction. This prevents backflow of gas and waste at the drain pipe 11, further reducing odor. Simultaneously, the check valve 7 can also be installed between the water valve 21 and the flushing ring pipe 22, allowing only water discharged from the water valve 21 to enter the flushing ring pipe 22. This also prevents backflow of water in the flushing ring pipe 22, ensuring that water discharged from the water valve 21 flows to the toilet bowl 1, facilitating water volume control.

[0070] Preferably, refer to Figure 1 The defecation system also includes a pressure sensor 43 installed in the vacuum tube 61. The pressure sensor 43 can detect the air pressure in the vacuum tube 61. The pressure sensor 43 is communicatively connected to the controller 5, so that the controller 5 can obtain the air pressure value of the vacuum tube 61. When the air pressure value of the vacuum tube 61 is greater than the preset air pressure value, the controller 5 starts the vacuum pump 62 to promptly draw the vacuum tube 61 back to a negative pressure state, thereby maintaining the suction force on the defecation chamber 311.

[0071] In a preferred embodiment, the vacuum tube 61 may be extended with a branch tube 63, which is also connected to the vacuum tube 61, so that the air pressure in the branch tube 63 is the same as that in the vacuum tube 61. Placing the pressure sensor 43 in the branch tube 63 can both detect the air pressure in the vacuum tube 61 and prevent dirt in the vacuum tube 61 from contaminating the pressure sensor 43, thus extending the service life of the pressure sensor 43.

[0072] Regarding the preferred structure of the telescopic module 33, refer to... Figure 1The telescopic module 33 includes an air pump 331 and an air pipe 332. The air pump 331 is connected to the actuation chamber 312 via the air pipe 332. When using the telescopic module 33 of this embodiment, driving the air pump 331 to draw air into the actuation chamber 312 through the air pipe 332 creates a negative pressure in the actuation chamber 312. Under atmospheric pressure, the elastic valves 32 contract towards the air pump 331, causing the two elastic valves 32 to move away from each other and opening the defecation chamber 311. Conversely, if the air pump 331 is driven to inflate the actuation chamber 312 through the air pipe 332 to create high pressure, under atmospheric pressure, the elastic valves 32 expand away from the air pump 331, causing the two elastic valves 32 to move closer to each other and closing the defecation chamber 311. By adjusting the suction direction or blowing direction of the air pump 331, and by adjusting the power of the air pump 331, the opening and closing efficiency of the defecation chamber 311 can be accelerated or decelerated. Furthermore, by increasing or decreasing the opening resistance of the defecation chamber 311 when it is closed, it can be adapted to the usage needs of different atmospheric environments.

[0073] Further, refer to Figure 1 The telescopic module 33 also includes a return spring 333, with its two ends abutting against the walls of the elastic valve 32 and the actuation chamber 312, respectively. This spring provides elastic force when the elastic valve 32 is relatively close to or far from the bottom of the actuation chamber 312. In this embodiment, the two ends of the return spring 333 in its relaxed state correspond to the position when the elastic valve 32 is partially open in the defecation chamber 311. This allows the return spring 333 to provide a restoring force to the elastic valve 32 whether it is fully open or fully closed, thereby reducing the suction and blowing power requirements of the air pump 331 on the air tube 332. Alternatively, the two ends of the return spring 333 in its relaxed state can correspond to the position when the elastic valve 32 is fully closed in the defecation chamber 311. The elastic force of the return spring 333 enables autonomous closure of the defecation chamber 311, reducing reliance on the inflation power of the air pump 331. Furthermore, the inflation function of the air pump 331 can be removed, and the two elastic valves 32 can be brought closer to each other only by the elastic reset of the return spring 333. The elastic valves 32 can be contracted only by the air pump 331 pumping air into the air tube 332, which can reduce the functional requirements of the air pump 331 and thus reduce the manufacturing cost of the defecation system.

[0074] In the defecation system of this application, the urinal 1 can be a toilet or a urinal. The number of urinals 1 can be one, two, or more. When there are two or more urinals 1, they can be connected in parallel through multiple vacuum tubes 61, allowing multiple vacuum tubes 61 to be pumped simultaneously by a single vacuum pump 62, reducing the complexity of pipework layout. To prevent the vacuum pump 62 from malfunctioning and failing to pump the vacuum tubes 61 in a timely manner, two or more vacuum pumps 62 can be installed, with adjacent vacuum pumps 62 connected in parallel. Only one vacuum pump 62 is activated at a time, while the others serve as backups. When the vacuum pump 62 in use malfunctions, the backup vacuum pump 62 can be used to replace the faulty pump and facilitate maintenance.

[0075] Optionally, the vacuum suction assembly 6 can be connected to a wastewater treatment device or directly to a wastewater collection device, depending on the specific application. (Reference) Figure 4 A shut-off valve 8 can be provided on the side of the vacuum suction assembly 6 away from the discharge assembly 3. When the shut-off valve 8 is closed, it can seal the vacuum tube 61 and prevent the gas in the vacuum tube 61 from being discharged by the vacuum pump 62, so that the vacuum suction assembly 6 of the defecation system of this application can be replaced in a sewage treatment device or a sewage collection device.

[0076] In addition, this application also provides a control method for a defecation system applied to any of the above embodiments, comprising:

[0077] S101. In response to the start information, start the vacuum pump 62 to draw vacuum tube 61 so that vacuum tube 61 is pre-stressed.

[0078] S102, Entering the sewage discharge cycle, including: opening the water valve 21 of the flushing component 2 so that water flows into the toilet bowl 1 through the through hole 23 of the flushing ring pipe 22, so that the sewage in the toilet bowl 1 enters the drain pipe 11; controlling the telescopic module 33 of the discharge component 3 to drive the two elastic valves 32 away from each other to open the sewage chamber 311 so that the vacuum tube 61 can suck the sewage in the drain pipe 11 through the opened sewage chamber 311; after the sewage leaves the toilet bowl 1, closing the water valve 21 and controlling the telescopic module 33 to drive the two elastic valves 32 closer to each other so that the closed sewage chamber 311 blocks the water and maintains the water in the drain pipe 11 to form a water seal;

[0079] S103. After the sewage discharge cycle is completed, the distance sensor 41 detects the actual distance between the two elastic valves 32. When the actual distance is greater than or equal to the preset distance, the sewage discharge cycle is entered again.

[0080] This application utilizes a vacuum pump 62, which is pre-activated in response to a start-up message, to draw suction from the vacuum tube 61, thus creating a negative pressure in the vacuum tube 61 beforehand. After the user finishes defecating, the waste disposal cycle begins. Specifically, the water valve 21 of the flushing assembly 2 is first opened, allowing water to flow through the flushing ring pipe 22 to flush the toilet bowl 1, causing the excrement in the drain pipe 11 to mix with the water and form waste. Then, the telescopic module 33 of the discharge assembly 3 is controlled to drive the two elastic valves 32 away from each other, thereby opening the waste disposal chamber 311. This allows the negative-pressure vacuum tube 61 to draw suction from the drain pipe 11 through the opened waste disposal chamber 311, discharging the waste from the toilet bowl 1. After the waste leaves the toilet bowl 1, the water valve 21 is closed and the telescopic module 33 is controlled to drive the two elastic valves 32 to move closer to each other, closing the defecation chamber 311. The closed defecation chamber 311 blocks the water from the drain pipe 11, so as to maintain the water in the drain pipe 11 to form a water seal, which can prevent odors and waste from flowing back into the drain pipe 11, and at the same time complete a sewage discharge cycle.

[0081] After the sewage discharge cycle is completed, the actual distance between the two elastic valves 32 detected by the distance sensor 41 is compared with a preset distance. If the actual distance is greater than or equal to the preset distance, it indicates that the sewage chamber 311 is not completely closed and there may be blockage. At this time, a new sewage discharge cycle is entered, which can reopen the sewage chamber 311 and flush it with water until the actual distance between the two elastic valves 32 is less than the preset distance, that is, until the blockage is sucked into the negative pressure vacuum tube 61.

[0082] The defecation system control method of this application can precisely control the opening and closing time of the water valve 21 and the vacuum pump 62, as well as control the extension and retraction of the telescopic module 33, thereby further precisely controlling the water usage and the opening and closing of the defecation chamber 311. This can reduce the blockage and incomplete closure of the defecation chamber 311, and also form a water seal to reduce odor and improve the user experience.

[0083] It should be noted that the triggering action for entering the sewage discharge cycle in this embodiment can be varied. For example, it can be a flush switch 9 connected to the controller 5, which is manually pressed by the user to trigger the sewage discharge cycle. Alternatively, it can be an infrared sensor connected to the controller 5, which can also trigger the sewage discharge cycle if the user leaves the toilet bowl 1 and the infrared sensor does not detect a human body. Similarly, a turbidity sensor or pressure sensor 43 can be installed in the toilet bowl 1, which is also connected to the controller 5. Both the turbidity sensor and the pressure sensor 43 can detect the presence of excrement in the toilet bowl 1, and trigger the sewage discharge cycle when excrement is present. This embodiment does not specifically limit the specific triggering action for entering the sewage discharge cycle.

[0084] Preferably, after the waste leaves the toilet bowl 1, the step of closing the water valve 21 and controlling the telescopic module 33 to drive the two elastic valves 32 closer to each other includes:

[0085] After the water valve 21 is opened, the timer 42 counts the opening time of the water valve 21. When the opening time reaches the first preset time, the water valve 21 is closed, which can promptly close the water valve 21 to cut off the water supply to the flushing ring pipe 22 and prevent water from overflowing the toilet bowl 1.

[0086] After the control telescopic module 33 drives the two elastic valves 32 to move away from each other and open the defecation chamber 311, the timer 42 times the action time of the telescopic module 33. When the action time reaches the second preset time, the control telescopic module 33 drives the two elastic valves 32 to move closer to each other, so as to close the defecation chamber 311 in time.

[0087] In this embodiment, the time it takes for waste to leave the toilet bowl 1 is simulated by timing the timer 42, which ensures that the sewage discharge cycle can be completed in a timely manner. The specific first and second preset times can be determined by referring to the actual time it takes for waste to leave the toilet bowl 1.

[0088] Furthermore, the extension or retraction timing of the telescopic module 33 can be controlled in conjunction with the opening and closing timing of the water valve 21. For example, when the opening time of the water valve 21 reaches the waiting time (the waiting time is earlier than the first preset time), the telescopic module 33 can be driven to contract, thereby driving the two elastic valves 32 to move away from each other. In other words, the water flow is first mixed with the excrement to form waste before the defecation chamber 311 is opened. This avoids the odor from being emitted through the drain pipe 11 after the defecation chamber 311 is opened first, and also avoids the water flow from entering the defecation chamber 311 directly without mixing with the excrement and being discharged through the vacuum tube 61. This reduces the direct action of the vacuum tube 61 on the atmospheric environment and reduces the suction force on the excrement. Furthermore, the defecation chamber 311 can be closed before the water valve 21, that is, the second preset time is earlier than the first preset time. The telescopic module 33 is controlled to drive the two elastic valves 32 to move closer to each other before the water valve 21 is closed. This ensures that the bottom of the toilet bowl 1 is equipped with a water seal when the defecation chamber 311 is opened and closed, which can further reduce the odor in the vacuum tube 61 from being transmitted to the toilet bowl 1 through the drain pipe 11.

[0089] Specifically, in the control method of the defecation system of this application, the step of activating the vacuum pump 62 to draw vacuum tube 61 in response to a start information includes:

[0090] Obtain the current air pressure of the vacuum tube 61 detected by the pressure sensor 43;

[0091] When the current air pressure is greater than the preset air pressure, a start-up message is generated, and in response to the start-up message, the vacuum pump 62 is started to draw vacuum tube 61.

[0092] This embodiment can determine whether the vacuum pump 62 needs to be started based on the current air pressure of the vacuum tube 61, so as to timely draw the vacuum tube 61 back to a negative pressure state, thereby maintaining the suction force on the defecation chamber 311.

[0093] Optionally, the step of the telescopic module 33 of the control emission assembly 3 driving the two elastic valves 32 away from each other includes:

[0094] By controlling the actuation chamber 312 of the air pump 331 to draw and discharge the component 3, the elastic valve 32 contracts toward the air pump 331 under atmospheric pressure, causing the two elastic valves 32 to move away from each other and open the defecation chamber 311.

[0095] Similarly, the step of controlling the telescopic module 33 to drive the two elastic valves 32 closer to each other includes:

[0096] The control air pump 331 inflates the action chamber 312 to form high pressure. Under the action of atmospheric pressure, the elastic valve 32 expands in the direction away from the air pump 331. At this time, it can drive the two elastic valves 32 to approach each other and close the defecation chamber 311.

[0097] This embodiment can accelerate or decelerate the opening and closing efficiency of the defecation chamber 311 by adjusting the suction or blowing direction of the air pump 331 and by adjusting the power of the air pump 331. Furthermore, by increasing or decreasing the opening resistance of the defecation chamber 311 when it is closed, it can adapt to the usage requirements of different atmospheric environments.

[0098] In addition, this application also provides another control method for the defecation system applied to any of the above embodiments, including:

[0099] S201. Obtain the current air pressure of the vacuum tube 61 detected by the pressure sensor 43; when the current air pressure is greater than the preset air pressure, generate a start information, and start the vacuum pump 62 in response to the start information to draw the vacuum tube 61 so that the vacuum tube 61 is pre-formed with negative pressure;

[0100] S202, Entering the sewage discharge cycle, including: opening the water valve 21 of the flushing component 2 so that water flows into the toilet bowl 1 through the through hole 23 of the flushing ring pipe 22, so that the sewage in the toilet bowl 1 enters the drain pipe 11; timing the opening time of the water valve 21 by the timer 42, and closing the water valve 21 when the opening time reaches the first preset time; controlling the air pump 331 to suck the action chamber 312 of the discharge component 3 so that the two elastic valves 32 move away from each other to open the sewage chamber 311, so that the vacuum tube 61 sucks the sewage in the drain pipe 11 through the opened sewage chamber 311; timing the action time of the telescopic module 33 by the timer 42, and controlling the air pump 331 to inflate the action chamber 312 when the action time reaches the second preset time, so that the two elastic valves 32 move closer to each other, and the closed sewage chamber 311 blocks the water and keeps the water forming a water seal at the drain pipe 11;

[0101] S203. After the sewage discharge cycle is completed, the distance sensor 41 detects the actual distance between the two elastic valves 32. When the actual distance is greater than or equal to the preset distance, the sewage discharge cycle is entered again.
