Description

Technical Field

[0001] This invention belongs to the field of sanitary ware technology, specifically a low-consumption vacuum toilet pulse flushing mechanism and sewage discharge method. Background Technology

[0002] A toilet, also known as a ceramic toilet, flush toilet, or sit-down toilet, is a sanitary appliance belonging to the field of building water supply and drainage materials. It is characterized by its seated position and is typically equipped with a low tank, toilet seat, and other accessories. Installed in the bathroom for urination and defecation, it can be flushed after use to maintain hygiene. Currently, public areas such as shopping malls are gradually transitioning to sit-down toilets, which are more inclusive of users such as the elderly, pregnant women, and people with disabilities who have difficulty squatting. Currently, most low-water-volume vacuum toilets on the market rely on a single high-flow siphon flush from the water tank to clean up waste, and are compatible with vacuum pipes for suction. However, when using the toilet, the inner wall of the toilet bowl has a high rate of waste adhesion, and the second flush consumes a lot of water. The forward flow of water from the main siphon flush in the water tank has limited flushing power and cannot remove dried and adhered waste. Users will most likely need to manually press the flush button two or three times to add water for flushing, or use a toilet brush to clean the feces stuck to the inner wall. However, this still requires a second flush to remove all the waste, which greatly increases the overall water consumption of the vacuum toilet. Summary of the Invention

A piston structure is provided on the other end of the L-shaped water inlet pipe away from the square drain plate. A small amount of water in the water tank flows out in a vortex shape from the five water outlets, so that a water film is formed on the inner wall of the toilet body. A conical cylinder is also fixedly connected to the L-shaped water inlet pipe. A variable cleaning structure is provided between the conical cylinder and the piston structure.

[0005] Preferably, the snap-fit ​​structure includes a ball handle that snaps onto the hollow filter plate.

[0007] Preferably, the piston T-rod can also be intermittently fitted with a T-shaped plate, and a sliding groove is provided in the top cylinder cavity of the piston cylinder to be fitted and slidably connected with the T-shaped plate. An elastic telescopic rod is fixedly connected between the outer wall of one end of the T-shaped plate and the groove wall near the water plug plate at one end of the sliding groove, and the rod body of the elastic telescopic rod is fitted and slidably connected with the top cylinder cavity of the piston cylinder.

[0008] Preferably, the elastic telescopic rod is composed of a sleeve, an extension rod, and an elastic element. The elastic element has high stiffness and small deformation under pressure. Both ends of the elastic element are fixedly connected to the sleeve wall and the extension rod body, respectively. An L-shaped groove is provided on the side of the piston cylinder away from the slide groove. The elastic telescopic rod is slidably connected to the groove wall of the L-shaped groove. The end of the elastic telescopic rod away from the T-shaped plate is fixedly connected to the outer wall of the water plug plate.

[0009] Preferably, elastic rubber cloth is fixedly connected between the outer walls of both ends of the T-shaped plate and the groove walls of both ends of the slide.

[0010] Preferably, the variable cleaning structure includes a sealing cap that is tightly snapped into the inner wall of the top of the conical cylinder, the conical cylinder and the L-shaped water inlet pipe are tightly fitted together, and a hollow connecting plate is fixedly connected between the conical cylinder and the L-shaped water inlet pipe. A hook is fixedly connected to the inner wall of the conical cylinder, and a cleaning ball is hung on the hook. The cleaning ball consists of a stick and a tightly glued mesh bag at the bottom of the stick, with cleaning particles inside the mesh bag.

[0011] Preferably, an arc-shaped stopper plate is attached to the inner wall of the conical cylinder, and two arc-shaped sliding plates are fixedly connected to the outer wall of the arc-shaped stopper plate. Two annular grooves are formed in the inner wall of the conical cylinder, and the two arc-shaped sliding plates are respectively attached to and rotatably connected to the groove walls of the two annular grooves.

[0012] Preferably, a T-shaped toothed block is fixedly connected to the bottom end of the arc-shaped slide plate, and a toothed plate is meshed on the T-shaped toothed block. The toothed plate is composed of a small toothed plate and a long smooth plate, and the end of the toothed plate away from the T-shaped toothed block is fixedly connected to the water plug plate.

[0013] A method for flushing wastewater from a low-consumption vacuum toilet, the specific operating steps of which are as follows: S1. Water in the tank flows through the square drain plate to the hollow filter plate for double-layer filtration (quartz sand / activated carbon for impurity and odor removal). It then enters the piston cylinder through the one-way valve, pre-filling the cylinder with 1 / 2 of its volume. When a person sits down, the infrared sensor triggers the electric telescopic rod to retract, driving the piston T rod to create negative pressure to push the water. The water is sprayed out through the 35-degree angled water nozzle as a low-pressure vortex water film, preventing direct adhesion of feces and reducing the adhesion of stubborn dirt from the source. The water consumption per cycle is extremely low. Subsequently, the hollow filter plate can be directly squeezed inward to compress the spring, releasing the ball handle buckle limit and allowing the filter plate to be manually removed to replace the purification particles. S2. When a person leaves the seat, an independent infrared sensor triggers the reciprocating motion of the electric telescopic rod. The piston T-rod pushes the T-shaped plate, which in turn pulls open the water plug plate, increasing the water flow rate of the L-shaped inlet pipe. The synchronous gear group rotates the arc-shaped plug plate, opening the water path of the conical cylinder, quickly filling the piston cylinder with water, and simultaneously activating the dissolution of cleaning particles, thus realizing the variable adjustment of water flow rate as needed. S3. By pressing the water tank drain button and simultaneously starting the vacuum suction, the electric telescopic rod retracts and pushes the wastewater into the cylinder. The toilet body is then flushed with a high-pressure secondary vortex at 0.35-0.5MPa. The double water volume with cleaning agent removes residual dried dirt, and the vacuum pipe thoroughly removes the dirt, eliminating the need for secondary flushing.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a hollow filter plate installed at the bottom of the water tank. The first layer relies on the filter plate to intercept large particles of scale, rust, and colloidal suspended matter. The second layer can be filled with quartz sand particles as needed. The quartz sand deeply intercepts fine silt and avoids clogging of the water outlet after long-term use. This invention utilizes a gear linkage structure consisting of a water plug plate, a toothed plate, and a T-shaped toothed block. Only when the cleaning function is needed for the off-site decontamination and rinsing process, the hollow connecting plate automatically opens with the displacement of the water plug plate, allowing some water to enter the conical cylinder to rinse the cleaning balls. During the low-water pre-wetting stage, the arc-shaped plug plate remains closed, preventing the addition of cleaning particles. This allows the cleaning agent to be started and stopped as needed, avoiding long-term dissolution and waste. The water flow carries the cleaning particles in the net bag, dynamically rolling and rinsing, increasing the particle dissolution rate. The dissolved wastewater is fully mixed with the main rinsing water. The high-pressure vortex water flow, combined with the cleaning agent, can peel off stubborn, dried-up dirt, compensating for the shortcoming that water films cannot guarantee 100% anti-sticking. This invention uses an independent infrared sensor to distinguish human sitting signals, pre-extracts water from half of the piston cylinder, and sprays a vortex of thin water film through five 35-degree circumferential water outlets at a water pressure of 0.35-0.5MPa. This forms a full-coverage lubricating layer on the inner wall of the toilet in advance, preventing feces from directly adhering to the ceramic glaze from the source, eliminating more than 80% of light dirt adhesion, and eliminating the need for subsequent water replenishment and flushing, thus achieving water-saving pre-lubrication of the wall before sitting. When a person leaves the toilet, the second set of infrared sensors is triggered, which simultaneously activates the main siphon flushing system in the water tank for a secondary pulse flush. The secondary flushing water flow is twice the amount of water used for pre-lubrication, reusing the original flushing water in the water tank without drawing additional tap water. Compared to traditional vacuum toilets, this reduces the total flushing water consumption, eliminates water waste caused by secondary flushing, and achieves enhanced cleaning when a person leaves the toilet. The water outlets all adopt a 35-degree inner wall angle design, so that the water flow is sprayed out along the tangent of the inner wall of the ring, forming a closed-loop vortex water flow. Compared with vertical water outlet, the inner wall flushing coverage area is comprehensively improved, and dirt in the dead corners of the ring is flushed without any omission.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 11As shown, the present invention provides a low-consumption vacuum toilet pulse flushing mechanism, including a toilet body 1, a water tank 101 fixedly mounted on the toilet body 1, a toilet seat 102 rotatably hinged to the toilet body 1, two independently detected infrared sensors fixedly mounted on the toilet body 1, five water outlets 103 arranged in a circular pattern in the inner wall of the toilet body 1, each water outlet 103 being arranged at a 35-degree angle to the inner wall of the toilet body 1, a square drain plate 201 fixedly connected to one side of the bottom end of the water tank 101, a hollow filter plate 202 inserted into one panel of the square drain plate 201, the hollow filter plate 202 being used to place purification particles, and a snap-fit ​​structure provided on the square drain plate 201; The snap-fit ​​structure includes a ball handle 203 that snaps onto the hollow filter plate 202. A slot 204 is provided in the inner wall of the square drain plate 201 away from the ball handle 203. Three springs 205 are fixedly connected to the inner wall of the slot 204. The other ends of the three springs 205 can intermittently fit and connect with the outer wall of the hollow filter plate 202 away from the ball handle 203. A U-shaped plate 206 is fixedly connected to the panel below the ball handle 203 on the square drain plate 201. A snap-fit ​​plate 207 can be intermittently fitted and snapped onto the ball handle 203. A shaft is fixedly connected to the plate near the bottom of the snap-fit ​​plate 207. Both sides of the shaft are rotatably connected to the inner wall of the U-shaped plate 206. An L-shaped water inlet pipe 2 is fixedly connected to the bottom plate of the square drain plate 201. A one-way valve 208 is fixedly connected to the L-shaped water inlet pipe 2.

[0019] Using the above scheme: the water flowing down from the water tank 101 passes through the hollow filter plate 202 inserted in the square drain plate 201 before entering the L-shaped inlet pipe 2. The hollow filter plate 202 filters out any scale that may be present in the water, preventing dirt from entering the L-shaped inlet pipe 2. Furthermore, the purification particles (quartz sand particles) placed inside the hollow filter plate 202 provide a deeper level of filtration. The quartz sand particles can intercept silt, rust, colloids, and fine suspended solids in the water, preventing impurities from clogging the outlet 103 over long-term use. After the hollow filter plate 202 has been used for a certain period of time, such as... Figure 4 and Figure 5 As shown, by squeezing the hollow filter plate 202 to make it penetrate deeper into the groove wall of the slot 204, the three springs 205 are squeezed, causing the three springs 205 to simultaneously deform under pressure. Consequently, the translation of the hollow filter plate 202 within the square drain plate 201 synchronously moves the ball handle 203 to the position of the slot plate 207. (See reference...) Figure 5As shown, the U-shaped plate 206 is U-shaped, so the only way to make contact with it is to move the clamping plate 207 around the shaft, rotating it 90 degrees from the opening of the U-shaped plate 206 to the hollow filter plate 202 and the ball handle 203 (the maximum rotation angle of the clamping plate 207 is only 90 degrees). The presence of the clamping plate 207 will create a resistance limit on the filter plate 202. Subsequently, the contact between the clamping plate 207 and the filter plate 202 can be released by manually moving the clamping plate 207 directly. In addition, the multiple springs 205 self- When the device is reset, the hollow filter plate 202 will pop out, making it easier for the user to pull out the hollow filter plate 202. Then, by holding the ball handle 203 and pulling the hollow filter plate 202, the particles inside the hollow filter plate 202 can be poured out and new purification particles can be added. The particles are placed as described above, adding the particulate matter that the user needs at the moment, so that it can be used flexibly. The water filtered by the hollow filter plate 202 will enter the piston cylinder 210 through the L-shaped water inlet pipe 2 and the one-way valve 208.

[0020] A piston structure is provided on the other end of the L-shaped water inlet pipe 2 away from the square drain plate 201, which causes a small amount of water in the water tank 101 to flow out from the five water outlets 103 in a vortex shape, so that a water film is formed on the inner wall of the toilet body 1 for lubrication. A conical cylinder 223 is also fixedly connected to the L-shaped water inlet pipe 2. The piston structure includes a water stopper plate 209 that blocks one end of the L-shaped inlet pipe 2 to control the water flow of the L-shaped inlet pipe 2. A piston cylinder 210 is fixedly connected to the end of the L-shaped inlet pipe 2 away from the square drain plate 201. The water stopper plate 209 and the inner wall of the piston cylinder 210 are intermittently fitted and snapped together. A water supply pipe 211 is fixedly connected between the piston cylinder 210 and the toilet body 1. This water supply pipe 211 is connected to the flow channels of the five water outlets 103. The water supply pipe 211 has... The body is tilted, so that when there is water inside the piston cylinder 210, it will not automatically enter the flow channels of the five water outlets 103 of the toilet body 1. A piston T rod 212 is slidably connected to the inner wall of the piston cylinder 210, and the rod of the piston T rod 212 is slidably connected to the end of the piston cylinder 210 away from the L-shaped water inlet pipe 2. A sleeve rod 213 is fixedly connected to the end of the piston T rod 212 that protrudes from the piston cylinder 210. The sleeve rod 213 consists of a vertical rod and a sleeve rod fixed to the top of the vertical rod. The piston cylinder 210 is composed of a collar. A support plate 215 is fixedly connected to the outer wall of the top of the piston cylinder 210. An electric telescopic rod 214 is fixedly connected to the outer wall of the support plate 215. The movable end of the electric telescopic rod 214 is fixedly connected to the collar on the sleeve rod 213. The plate of the support plate 215 is also fixedly connected to the water tank 101. The piston T rod 212 can also be intermittently fitted with a T-shaped plate 216. A sliding contact is provided in the top cylinder cavity of the piston cylinder 210 to fit and slide against the T-shaped plate 216. The connecting groove 217, the outer wall of one end of the T-shaped plate 216 and the groove wall of the groove 217 near the water plug plate 209 are jointly and fixedly connected by an elastic telescopic rod 218. The rod body of the elastic telescopic rod 218 is in close sliding connection with the inner cavity of the top cylinder of the piston cylinder 210. The elastic telescopic rod 218 is composed of a sleeve, an extension rod and an elastic element. The elastic element has high rigidity and small deformation under pressure. The two ends of the elastic element are respectively jointly and fixedly connected to the cylinder wall of the sleeve and the rod body of the extension rod.

[0021] The above solution is adopted: such as Figure 6As shown, when the water passing through the L-shaped inlet pipe 2 and the water stopper plate 209 fills half of the piston cylinder 210, it can provide a water film lubrication for the inner wall of the toilet body 1 when the user uses the toilet body 1 next time. Specifically, when a user sits on the toilet seat 102, one of the infrared sensors installed on the toilet body 1 will automatically sense the human body, thereby directly triggering the operation of the electric telescopic rod 214 installed on the support plate 215. The retraction of the electric telescopic rod 214 will drive the sleeve rod 213 and the piston T rod 212 fixed below the sleeve rod 213 to move synchronously. As a result, the piston T rod 212 will create a piston negative pressure in the piston cylinder 210. The resulting squeezing force will push the water stored in the piston cylinder 210, causing the water to pass through the pump. Water pipe 211 enters the toilet body 1. Immediately, water flows out through five spouts 103 (water pressure 0.35~0.5MPa) arranged at a 35-degree angle around the inner wall of the toilet body 1, forming a vortex water flow. A small amount of water is sprayed onto the inner wall of the toilet body 1, forming a water film for lubrication, thereby reducing the direct adhesion of dirt (feces), reducing the difficulty of subsequent flushing and water consumption (avoiding secondary flushing). The water is squeezed out only from the water supply pipe 211. Because a one-way valve 208 is installed on the L-shaped water inlet pipe 2, backflow of water due to pressure is prevented. After all the water is squeezed out, the electric telescopic rod 214 extends and returns to its original position, which can further accelerate the water replenishment speed. Then the electric telescopic rod 214 stops operating. Figures 6 to 9 As shown, until the human body stands up and is detected by another independently detected infrared sensor, the human body immediately presses the drain button on the water tank 101. At this time, the other independently detected infrared sensor will activate the electric telescopic rod 214 after the human body stands up and before turning around to press the drain button on the water tank 101. The rod will first extend (synchronously driving the piston T rod 212 to move), then retract, and finally return to the middle area of ​​the piston cylinder 210. When the electric telescopic rod 214 extends first, the piston T rod 212 driven by it will contact the T-shaped plate 216 during the movement, causing the T-shaped plate 216 to be subjected to resistance and passively move within the slide groove 217. During the movement, the T-shaped plate 216 will synchronously drive the piston T rod 212 to move. The elastic telescopic rod 218, fixed on one end of the outer wall, is limited and moves within the cylinder wall of the piston cylinder 210. Because the elastic element (coil spring) in the elastic telescopic rod 218 is stronger than that of ordinary elastic elements, the rod of the elastic telescopic rod 218 will not extend when it is subjected to force. As a result, the elastic telescopic rod 218 is subjected to force and drives the water plug plate 209 to move, causing the water plug plate 209 to disengage from the piston cylinder 210. Without the water plug plate 209 blocking, the hole at the connection between the L-shaped water inlet pipe 2 and the piston cylinder 210 will be fully opened. The water flowing out through the L-shaped water inlet pipe 2 becomes larger, which can increase the speed at which the water in the water tank 101 enters the piston cylinder 210 through the L-shaped water inlet pipe 2.

[0022] An L-shaped groove 219 is provided on the inner wall of the piston cylinder 210 away from the slide groove 217. The extension rod of the elastic telescopic rod 218 is slidably connected to the groove wall of the L-shaped groove 219. The end of the elastic telescopic rod 218 away from the T-shaped plate 216 is fixedly connected to the outer wall of the water plug plate 209. Elastic rubber cloth 220 is fixedly connected between the outer walls of both ends of the T-shaped plate 216 and the groove walls of both ends of the slide groove 217. A spring 221 is fixedly connected to the outer wall of the end of the T-shaped plate 216 away from the elastic telescopic rod 218. The other end of the spring 221 away from the T-shaped plate 216 is fixedly connected to the groove wall of the slide groove 217. A positioning pin 222 is also fixedly connected in the groove wall of the slide groove 217. The T-shaped plate 216 and the positioning pin 222 can intermittently contact each other.

[0023] Using the above solution: As mentioned above, the L-shaped water inlet pipe 2 is no longer blocked by the water plug plate 209. At the same time, the translation of the elastic telescopic rod 218 will also abut against the opened L-shaped groove 219. Under the continuous translation and stretching of the piston T rod 212, the elastic telescopic rod 218 is subjected to additional resistance, which will cause the internal elastic element to deform. Thus, the movable end extension rod of the elastic telescopic rod 218 continues to follow the translation of the piston T rod 212, while the passive translation of the T-shaped plate 216 will compress the spring 221 to produce contraction deformation, and The elastic rubber cloth 220 that seals the bottom of the chute 217 is squeezed to prevent water from entering the chute 217. This continues until the T-shaped plate 216 is pressed against the positioning pin 222 fixed in one end of the chute 217. This also indicates that the piston T-rod 212 has moved to contact the cylinder wall of the piston cylinder 210. The increased water flow at the water inlet of the piston cylinder 210 and the suction negative pressure formed by the passive translation of the piston T-rod 212 can quickly fill the space inside the piston cylinder 210 with water, reducing the time difference between the water tank 101 draining water and the water inlet.

[0024] A variable cleaning structure is provided between the conical cylinder 223 and the piston structure; The variable cleaning structure includes a sealing cap 225 tightly fitted into the inner wall of the top of a conical cylinder 223. The conical cylinder 223 and the L-shaped water inlet pipe 2 are tightly fitted together, and a hollow connecting plate 224 is fixedly connected between them. A hook 226 is fixedly connected to the inner wall of the conical cylinder 223, and a cleaning ball 227 is hung on the hook 226. The cleaning ball 227 consists of a rod body and a tightly adhered mesh bag at the bottom of the rod body, containing cleaning particles. An arc-shaped stopper plate 228 is fitted to the inner wall of the conical cylinder 223. Two arc-shaped sliding plates 2281 are fixedly connected to the outer wall of the arc-shaped plug plate 228. Two annular grooves 229 are opened in the inner wall of the conical cylinder 223. The two arc-shaped sliding plates 2281 are respectively fitted and rotated with the groove walls of the two annular grooves 229. A T-shaped toothed block 230 is fixedly connected to the bottom end of the arc-shaped sliding plate 2281. A toothed plate 231 is meshed on the T-shaped toothed block 230. The toothed plate 231 is composed of a small toothed plate and a long smooth plate. The end of the toothed plate 231 away from the T-shaped toothed block 230 is fixedly connected to the water plug plate 209.

[0025] The above solution is adopted: such as Figure 6 and Figure 10 , Figure 11As shown, the passively shifting water plug plate 209 synchronously pulls the toothed plate 231 fixed to it, causing the toothed plate 231 and the T-shaped toothed block 230 meshing with it to briefly rotate. The passively rotating T-shaped toothed block 230 synchronously drives the arc-shaped plug plate 228 fixed on the outer wall to rotate in contact with the conical cylinder 223. Thus, the arc-shaped plug plate 228 can release the blockage of the hollow connecting plate 224, causing some of the water entering from the L-shaped water inlet pipe 2 to flow into the cavity of the conical cylinder 223. The passively rotating arc-shaped plug plate 228 will slide and engage in the two corresponding annular grooves 229 opened in the conical cylinder 223 through the two arc-shaped sliding plates 2281 fixed on the plate, achieving the effect of limiting rotation. Therefore, the water entering the conical cylinder 223 will inevitably flow out. The water flows through the cleaning ball 227 hanging on the hook 226, making direct contact with the cleaning particles inside the cleaning ball 227. As the water flows continuously through the inside of the cleaning ball, it carries the built-in cleaning particles, creating dynamic rolling. The surface of the cleaning particles is then dissolved, and the water, carrying a cleaning effect, flows through the bottom of the conical cylinder 223 and the L-shaped inlet pipe 2. The water with a cleaning effect then enters the piston cylinder 210 through the L-shaped inlet pipe 2, filling the entire cavity of the piston cylinder 210. At this point, the water has a cleaning effect. Afterward, the electric telescopic rod 214 retracts, causing the sleeve rod 213 and the piston T rod 212 to move synchronously. The piston T rod 212 pushes the cleaning water filling the piston cylinder 210 cavity, causing the water to be pressurized again. The water enters the toilet body 1 through the water supply pipe 211 and then flows directly out from the five water outlets 103 at a 35-degree angle. The water sprayed from the five outlets 103 has a completely different effect than the previous spray. The water flow rate is twice that of the previous water film lubrication, and the water is mixed with cleaning agents. When the water tank 101 flushes the toilet body 1, it simultaneously cleans the inner wall of the toilet body 1, directly carrying away the cleaning agents. The high-pressure flushing under vortex conditions completely prevents feces from sticking to the inner wall of the toilet body 1. Since the water film lubrication effect cannot completely prevent sticking to the inner wall of the toilet body 1, the added cleaning and flushing effect effectively handles any sticking problems that may occur. Furthermore, the piston cylinder 210... All the water used is disposable rinsing water from water tank 101. A small amount of the existing rinsing water is pumped out for use, reducing the generation of additional water resources. When piston T rod 212 pushes the filled cleaning water in piston cylinder 210, T-shaped plate 216 and spring 221 are not under pressure. Therefore, under the elastic reset of spring 221, T-shaped plate 216 moves in real time, following the movement of piston T rod 212. As a result, elastic telescopic rod 218 will elastically reset. After continuous reset and translation, elastic telescopic rod 218 will synchronously drive water plug plate 209 to reset and re-fit and engage in piston cylinder 210. The reset of water plug plate 209 will also drive toothed plate 231 to mesh with T-shaped toothed block 230 again.Furthermore, the meshing drive produces a reverse rotation from the previous direction of rotation, causing the arc-shaped sliding plate 2281 to synchronously reset, sealing one end of the hollow connecting plate 224 again to prevent water from flowing in. After flushing, the electric telescopic rod 214 then indirectly drives the piston T rod 212 to reset to the center position of the piston cylinder 210, preparing for the next operation.

[0026] One additional point to note: For example Figure 1 and Figure 3 , Figure 4 , Figure 5 As shown, during the water storage process after flushing, the water in the water tank 101 first passes through the L-shaped water inlet pipe 2 and the square water outlet plate 201 to store water in the piston cylinder 210, so that half of the cavity in the piston cylinder 210 is filled with water. After half of the space in the piston cylinder 210 is filled, the water level in the water tank 101 will continue to rise until the water is full during the continuous water intake process.

[0027] It is worth noting that the second flushing motion containing cleaning agents is carried out simultaneously with the flushing of water tank 101. The flushing and siphoning effect of water tank 101, combined with the pulse vortex flushing, sucks all the sewage and loose dirt into the vacuum pipeline, achieving a residue-free cleaning. When a person stands up, an infrared sensor detects the movement, negative pressure water flows out, the water carries cleaning components, and the cleaning water fills the inner cavity of the toilet bowl. Then, when the person turns around and presses the drain button on the water tank 101, the piston negative pressure guides all the cleaning water into the toilet body 1, flushing and removing dirt from its inner wall, achieving residue-free cleaning and avoiding secondary or multiple flushes.

10. A method for discharging waste from a low-consumption vacuum toilet, applied to the pulse flushing mechanism of a low-consumption vacuum toilet as described in claim 9, characterized in that: The specific steps are as follows: S1. Water in the water tank (101) flows through the square drain plate to the hollow filter plate (202) for double-layer filtration (quartz sand / activated carbon for impurity and odor removal). It enters the piston cylinder (210) through the one-way valve and is pre-filled with 1 / 2 volume of water. Then, when a person sits down, the infrared sensor triggers the electric telescopic rod (214) to retract, driving the piston T rod (212) to form a negative pressure to push water. The water is sprayed out through the 35-degree angled water outlet (103) to form a low-pressure vortex water film, blocking the direct adhesion of feces and reducing the adhesion of stubborn dirt from the source. The water consumption per use is extremely low. Afterwards, the hollow filter plate (202) can be directly squeezed inward to compress the spring, release the ball handle (203) buckle limit, and the filter plate can be manually removed to replace the purification particles. S2. When the human body leaves the seat, the independent infrared sensor triggers the electric telescopic rod (214) to reciprocate. The piston T rod (212) pushes the T-shaped plate (216), which in turn pulls open the water plug plate (209) and expands the water flow of the L-shaped water inlet pipe (2). The synchronous gear group rotates the arc-shaped plug plate (228) to open the water path of the conical cylinder (223), quickly fills the piston cylinder (210) with water, and simultaneously activates the dissolution of cleaning particles, so as to realize the water flow rate can be adjusted as needed. S3. By pressing the water tank (101) to drain water and simultaneously starting the vacuum suction, the electric telescopic rod (214) retracts and pushes the sewage body inside the cylinder, and uses a high pressure of 0.35-0.5MPa to flush the inner wall of the toilet body (1) with a secondary vortex. Relying on the double water volume with cleaning agent, the residual dried dirt is removed, and the dirt is completely sucked away with the vacuum pipeline, eliminating the need for secondary flushing.
