Description

Technical Field

[0001] This invention is an intelligent pressure-boosting flushing valve, belonging to the field of bathroom technology. Background Technology

[0002] A toilet is a sanitary fixture used for excretion and flushing, also known as a latrine, toilet bowl, or urinal. It is an important component of modern sanitation facilities, used to collect and dispose of bodily waste. Typically, a toilet consists of a tank and a seat. The seat, above the tank, provides a convenient platform for sitting. Below the seat is usually a drain hole for discharging waste into the sewer. The tank inside the toilet typically contains a flushing mechanism; when the flush button is pulled or the flush handle is lifted, water in the tank flushes the drain hole, flushing waste into the sewer. In traditional toilet designs, the tank is used to store water and build up water pressure to provide the pressure needed for flushing. However, existing tank designs require a significant amount of space, and because the pressure is limited by the amount of water flowing out of the tank, when the interval between flushes is short, the amount of water in the tank is small, leading to low internal water pressure. This can result in insufficient flushing pressure, making it difficult to flush the toilet properly. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide an intelligent pressure-boosting flushing valve. In traditional toilet designs, the tank stores water and accumulates pressure to provide the necessary pressure for flushing. However, existing tank designs require significant space, and because the pressure is limited by the water flow rate, when the interval between flushes is short, the water level in the tank is low, leading to insufficient internal water pressure. This results in inadequate flushing pressure and difficulty in thoroughly cleaning the toilet.

[0004] To achieve the above objectives, the present invention provides a smart pressure-boosting flushing valve.

[0005] A smart booster flushing valve, comprising:

[0006] The main valve sleeve includes an inlet pipe connected to the external water flow on one side of the main valve sleeve, and an outlet pipe connected to the external toilet on one side of the main valve sleeve. The outlet pipe includes a first flush pipe connected to the upper flushing part of the external toilet, and a second flush pipe connected to the lower flushing part of the toilet.

[0007] The water inlet pressurization mechanism is installed inside the main valve sleeve and is connected to the water inlet pipe.

[0008] The water inlet booster mechanism is installed inside the main valve sleeve, and the water inlet booster mechanism is connected to the first flushing pipe and the second flushing pipe.

[0009] An active switching mechanism is installed inside the main valve sleeve. The active switching mechanism controls the water pressure boosting mechanism to switch the connection state between the first flushing pipe and the second flushing pipe.

[0010] The air pump switch assembly installed on the main valve sleeve controls the connection status between the inlet booster mechanism and the outlet booster mechanism.

[0011] The water inlet booster mechanism includes a first water inlet booster component disposed inside the main valve sleeve, and a second water inlet booster component connected to the first water inlet booster component. The first water inlet booster component is connected to the water inlet pipe, and the water pressure of the pre-charged water flow is enhanced through the first water inlet booster component and the second water inlet booster component.

The annular sealing plate is in contact with the inner side of the first pressurization cavity, and the lower part of the annular sealing plate abuts against the upper end of the first spring.

[0013] Water flow is introduced into the cavity below the first booster rod, pushing the first booster rod upward. With the help of the sealing ring, a first booster space can be formed above the first booster rod. With the help of the stretched first spring, a second booster space can be formed below the first booster rod. The first booster cavity is formed in the first inner cavity through the cooperation of the first booster space and the second booster space.

A valve cover is sleeved on the outside of the rubber sleeve, and the air valve sleeve is airtightly connected to the first conduit.

[0017] It also includes a push rod rotatably installed in the main valve sleeve. One end of the push rod abuts against the valve cover, and the other end of the push rod is rotatably fitted with a sealing block. The sealing block is used to block the valve port in the water inlet pressurization mechanism. A third spring is fixedly installed on the side of the sealing block facing the valve port. The push rod is reset by pulling the sealing block through the third spring.

[0018] As a further improvement, the water outlet pressurization mechanism includes a pressure relief start assembly, a first water outlet pressurization assembly, and a second water outlet pressurization assembly disposed inside the air valve sleeve. The pressure relief start assembly is connected to the pump pressure switch assembly, the pressure relief start assembly is connected to the first water outlet pressurization assembly, and the first water outlet pressurization assembly is connected to the second water outlet pressurization assembly.

[0019] As a further improvement, the pressure relief start assembly includes a third cavity disposed inside the valve sleeve, a third booster rod slidably disposed inside the third cavity, and a fourth spring disposed between the third cavity and the third booster rod. A third sealing ring is embedded in the outer ring surface of the third booster rod facing the fourth spring. The third cavity is connected to the valve port, and a guide port is provided inside the third cavity. The guide port is located in the third cavity on the side where the fourth spring is located.

[0020] As a further improvement, the first water outlet pressurization assembly includes a fourth cavity disposed inside the air valve sleeve, a fourth pressurization rod slidably disposed inside the fourth cavity, an opening groove disposed above the middle of the fourth pressurization rod, and a fifth spring disposed in the fourth cavity and inserted into the opening groove. A sealing plate is provided above the fourth pressurization rod, and a fourth sealing ring is embedded in the outer circumference of the sealing plate.

[0021] The first water outlet pressurization component also includes a guide sleeve fixedly installed below the fourth pressurization rod. The guide sleeve is provided with a switching channel. The fourth pressurization rod drives the guide sleeve to slide up and down, switching the water flow state of the switching channel.

[0022] As a further improvement, the second water outlet pressurization assembly includes a fifth cavity extending downward from the fourth cavity, a fifth pressurization rod slidably disposed inside the fifth cavity, and a sixth spring mounted on the outer ring surface below the fifth pressurization rod. The fifth pressurization rod is located below the fourth pressurization rod, and the fourth pressurization rod passes through the fifth pressurization rod from top to bottom. The fourth cavity and the fifth cavity are connected, and the side of the fifth cavity is connected to the second inner cavity.

[0023] As a further improvement, the active switching mechanism includes a sixth cavity disposed inside the valve sleeve, a switching rod slidably installed inside the sixth cavity, a seventh spring sleeved in the middle of the switching rod, the switching rod dividing the sixth cavity into an upper cavity and a lower cavity, one side of the upper cavity of the sixth cavity communicating with the fifth cavity, a first connecting port provided above the sixth cavity, the sixth cavity communicating with the first flushing pipe through the first connecting port, the lower cavity of the sixth cavity communicating with the switching channel, a second connecting port provided in the middle of the switching rod, a blocking part provided in the middle of the sixth cavity, the blocking part blocking the second connecting port, the second connecting port communicating with the second flushing pipe.

[0024] The beneficial effects of this invention are:

[0025] This invention incorporates an inlet pressurization mechanism, an outlet pressurization mechanism, an active switching mechanism, and an air pump switch assembly. During use, water flows through the inlet pipe into the inlet pressurization mechanism inside the main valve sleeve. The inlet pressurization mechanism initially pressurizes the incoming water to form a pre-charge pressure. Due to the small size of the equipment, the amount of water entering is limited, making it easy to form a pre-charge pressure. The air pump switch assembly constrains the pre-charge water flow, keeping it in a constant pressure state and ensuring that the pre-charge pressure remains stable.

[0026] When flushing is required, the air pump switch assembly introduces gas pressure, controlling the opening of the water pressure boosting assembly. This releases the main valve sleeve, connecting the water pressure boosting assembly to the water inlet assembly, and water flows through the first flush pipe, creating a high-pressure flush on the toilet bowl. In the middle of the release phase, as the water pressure boosting assembly depressurizes, it drives the active switching assembly to switch between the first and second flush pipes, creating impact pressure on the toilet bowl and generating a siphon effect for drainage. In the later stages of the release phase, as the water pressure boosting assembly continues to depressurize, the active switching assembly is automatically disconnected, resetting and switching back between the first and second flush pipes. This provides a slow-release pressure to the toilet bowl, allowing the toilet bowl to return to a water-sealed state for future use. It can achieve multi-stage flushing and intelligently and actively switch the flushing state during the multi-stage flushing process. Through the multi-stage pressurization linkage design, it can flush the toilet under low water pressure. It does not require electricity because it relies entirely on mechanical structure. And because of its small size, there are no restrictions on the location of use. It does not need to be placed on top of the toilet or in a specific position. Its small size makes it suitable for most toilets. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 a part of the embodiments of the present invention, not all of them. 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. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. 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.

[0041] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] In existing traditional toilet designs, the tank is used to store water and accumulate water pressure to provide the pressure needed for flushing. However, existing tank designs require a large amount of space, and because the pressure is limited by the amount of water flowing out of the tank, when the interval between two flushes is short, the amount of water in the tank is small, which easily leads to low internal water pressure. Therefore, the toilet may not be flushed thoroughly due to relatively low flushing pressure. To solve the above-mentioned technical problems, this invention discloses the following technical solution:

[0044] Reference Figure 1-11 As shown, an intelligent booster flushing valve includes:

[0045] The main valve sleeve 1 includes an inlet pipe 2 connected to external water flow on one side of the main valve sleeve 1, and an outlet pipe 3 connected to an external toilet on one side of the main valve sleeve 1. The outlet pipe 3 includes a first flush pipe 31 connected to the upper flushing part of the external toilet, and a second flush pipe 322 connected to the lower flushing part of the toilet.

[0046] The water inlet pressurization mechanism is installed inside the main valve sleeve 1 and is connected to the water inlet pipe 2.

[0047] The water inlet booster mechanism is installed inside the main valve sleeve 1 and is connected to the first flush pipe 31 and the second flush pipe 322.

[0048] The active switching mechanism installed inside the main valve sleeve 1 controls the water pressure boosting mechanism to switch the connection state between the first flushing pipe 31 and the second flushing pipe 322.

[0049] The air pump switch assembly installed on the main valve sleeve 1 controls the connection status between the inlet booster mechanism and the outlet booster mechanism.

[0050] During use, water flows through the inlet pipe 2 into the water inlet pressurization mechanism inside the main valve sleeve 1. The water inlet pressurization mechanism initially pressurizes the incoming water to form a pre-charge pressure. Since the equipment is small in size, the amount of water entering is limited, which can easily form a pre-charge pressure. The pre-charge water flow is constrained by the air pump switch assembly to keep it in a constant pressure state and keep the pre-charge pressure stable.

[0051] When flushing is required, the gas pressure is introduced by activating the air pump switch assembly, controlling the opening of the water pressure boosting assembly. This causes the main valve sleeve 1 to enter a release state. In the release state, the water pressure boosting assembly is connected to the water inlet pressure boosting assembly, and water flows out through the first flush pipe 31, creating a high-pressure flush on the toilet bowl. In the middle of the release state, as the water pressure boosting assembly depressurizes, it drives the active switching assembly to switch the water output states of the first flush pipe 31 and the second flush pipe 322, creating an impact pressure on the bottom of the toilet bowl, which then achieves drainage and sewage discharge through a siphon effect. In the later stage of the release state, as the water pressure boosting assembly continues to depressurize, the power of the active switching assembly is actively disconnected, causing it to reset. This allows the second flush pipe 322 to switch the water output states of the first flush pipe 31 again, creating a slow-release pressure water inlet to the toilet bowl, allowing the bottom of the toilet bowl to enter a water-sealed state for the next use.

[0052] With a single start of the air pump switch assembly, the flush valve completes the entire multi-stage toilet flushing process using different water pressures.

[0053] The water inlet booster mechanism includes a first water inlet booster component 41 disposed inside the main valve sleeve 1, and a second water inlet booster component 42 connected to the first water inlet booster component 41. The first water inlet booster component 41 is connected to the water inlet pipe 2, and the water pressure of the pre-charged water flow is enhanced through the first water inlet booster component 41 and the second water inlet booster component 42.

[0054] The first water inlet booster assembly 41 includes a first inner cavity 411 integrally disposed inside the main valve sleeve 1, a first booster rod 412 slidably mounted inside the first inner cavity 411, an annular sealing piece 413 disposed on the side of the first booster rod 412, and a first spring 414 sleeved below the first booster rod 412. The annular sealing piece 413 fits against the inner side of the first booster cavity, and the lower part of the annular sealing piece 413 abuts against the upper end of the first spring 414.

[0055] To further enhance airtightness, a first sealing ring is also installed on the side of the first pressurizing rod 412 away from the first spring 414.

[0056] Water flow is introduced into the cavity below the first booster rod 412, pushing the first booster rod 412 upward. With the help of the sealing ring, a first booster space can be formed above the first booster rod 412. With the help of the stretched first spring 414, a second booster space can be formed below the first booster rod 412. The first booster cavity is formed in the first inner cavity 411 through the cooperation of the first booster space and the second booster space.

[0057] When the water flow is released, the compressed gas inside the first pressurization space generates a pushing force on the first pressurization rod 412. At the same time, when the stretched first spring 414 resets through its elastic potential energy, it generates a pulling force on the first pressurization rod 412. The combined force of the pushing and pulling forces simultaneously generates a pushing pressure on the water flow.

[0058] The first spring 414 is made of spring steel, with a length of 1 cm and a cross-sectional thickness of 1 mm. It can increase the force by 30-60 N, and through the first pressurization chamber, it can increase the water pressure of the pre-filled water flow by 1.8-2.1 MPa. In this embodiment, the first spring 414 has a diameter of 2.5 mm, which can increase the force by 46 N, and through the first pressurization chamber, it can increase the water pressure of the pre-filled water flow by 2.12-2.14 MPa.

[0059] The second water inlet booster assembly 42 includes a second inner cavity 421 integrally disposed inside the main valve sleeve 1, a second booster rod 422 slidably disposed in the second inner cavity 421, a second spring 423 sleeved in the middle of the second booster rod 422, and a second sealing ring 424 sleeved on the second booster rod 422. A partition 425 is provided in the middle of the second inner cavity 421. The partition 425 is fixedly connected to one end of the second spring 423, and the other end of the second spring 423 is fixedly connected to the second booster rod 422. The side of the partition 425 away from the second spring 423 is in contact with the second sealing ring 424. The cavity in the second inner cavity 421 facing the sealing ring is connected to the first inner cavity 411.

[0060] To further enhance airtightness, a third sealing ring 426 is also installed on the side of the first pressure boosting rod 412 near the first spring 414.

[0061] Pre-filled water flows into the second inner cavity 421 through the first inner cavity 411. The water pressure pushes the second booster rod 422 to move laterally, while the second spring 423 is stretched. This causes the cavity on the side of the second booster rod 422 near the third sealing ring 426 to form a third booster space, while the side of the second booster rod 422 where the second spring 423 is located forms a fourth booster space. The cooperation between the third and fourth booster spaces forms a second booster chamber in the second inner cavity 421.

[0062] When the water flow is released, the compressed gas inside the third pressurization space generates a first pushing force on the second pressurization rod 422. At the same time, when the stretched second spring 423 resets through its elastic potential energy, it generates a second pushing force on the second pressurization rod 422. The resultant force of the first pushing force and the second pushing force simultaneously generates a pushing pressure on the water flow.

[0063] The second pressurization chamber can increase the water pressure of the pre-charged water flow by 1.2-1.4 MPa.

[0064] The second spring 423 is made of spring steel, with a length of 0.7 cm and a spring cross-section thickness of 0.5 mm. It can increase the force by 10-20 N, and through the second pressurization chamber, it can increase the water pressure of the pre-filled water flow by 0.6-0.7 MPa. In this embodiment, the first spring 414 can increase the force by 15 N, and through the first pressurization chamber, it can increase the water pressure of the pre-filled water flow by 0.63-0.65 MPa.

[0065] The air pump switch assembly includes an air pump button valve 71 disposed outside the main valve sleeve 1 and a pump pressure switch assembly disposed inside the main valve sleeve 1. The air pump button valve 71 and the pump pressure switch assembly are connected through a first conduit 721.

[0066] The air pump button valve 71 is a device used to control the inflation and deflation of the air pump. It is commonly used in items that require inflation via an air pump, such as air mattresses, hovercrafts, and swimming rings.

[0067] The air pump button valve 71 consists of a button, a valve body, and a spring. When not pressed, the spring inside the valve body pushes the valve body upward, disconnecting the valve body from the inflation port and preventing airflow from the air pump.

[0068] When the button is pressed, the pressure causes the valve body to compress the spring and move downwards, connecting the valve body to the inflation port. This allows airflow from the air pump to pass through the valve body into the inflatable item, thus inflating it.

[0069] When the button is released, the spring pushes the valve body upward, disconnecting the connection and stopping the airflow into the inflatable item. Thus, the air pump can be controlled by pressing and releasing the button during inflation and deflation.

[0070] The air pump button valve 71 is designed to effectively control the airflow, providing convenient, fast, and reliable inflation and deflation operations. It is widely used in many outdoor activities and daily life. In this embodiment, the air pump button valve 71 is a conventional air pump button valve 71. When flushing is required, the air pump button valve 71 is pressed, which then delivers gas through the first conduit 721 towards the pump pressure switch assembly, thereby activating the pump pressure switch assembly. In other embodiments, an electronic air pump can also be used as a trigger valve, controlling the electronic air pump to deliver gas to the pump pressure switch assembly.

[0071] The pump pressure switch assembly includes an air valve sleeve 722 integrally disposed inside the main valve sleeve 1, a rubber sleeve 723 disposed on one side of the air valve sleeve 722, a valve cover 724 sleeved on the outside of the rubber sleeve 723, and the air valve sleeve 722 being airtightly connected to the first conduit 721.

[0072] It also includes a push rod 725 rotatably installed in the main valve sleeve 1. One end of the push rod 725 abuts against the valve cover 724, and the other end of the push rod 725 is rotatably fitted with a sealing block 726. The sealing block 726 is used to block the valve port 515 in the water inlet pressurization mechanism. A third spring 727 is fixedly installed on the side of the sealing block 726 facing the valve port 515. The push rod 725 is pulled by the third spring 727 to reset the sealing block 726.

[0073] In use, when airflow is introduced into the valve sleeve 722 through the first conduit 721, the valve sleeve 722 is sealed by the rubber sleeve 723 and the valve cover 724. When the internal pressure of the valve sleeve 722 increases, the expanding rubber strip pushes up the valve cover 724, which in turn pushes up the push rod 725 abutting against one end of the valve cover 724. The push rod 725 pulls the sealing block 726 away from the valve port 515, thereby activating the water inlet pressurization mechanism. During reset, when the air pressure in the rubber sleeve 723 is released, the elastic potential energy of the third spring 727 can pull the sealing block 726, thereby controlling the push rod 725 to reset.

[0074] The water outlet pressurization mechanism includes a pressure relief start component, a first water outlet pressurization component, and a second water outlet pressurization component disposed inside the air valve sleeve 722. The pressure relief start component is connected to the pump pressure switch component, the pressure relief start component is connected to the first water outlet pressurization component, and the first water outlet pressurization component is connected to the second water outlet pressurization component.

[0075] The pump pressure switch assembly drives the pressure relief start assembly to activate the first outlet water booster assembly, allowing the water flow to be further pressurized by passing through the first and second outlet water booster assemblies, as detailed below:

[0076] The pressure relief start assembly includes a third cavity 511 disposed inside the valve sleeve 722, a third booster rod 512 slidably disposed inside the third cavity 511, and a fourth spring 513 disposed between the third cavity 511 and the third booster rod 512. A third sealing ring 514 is embedded in the outer ring surface of the third booster rod 512 facing the fourth spring 513. The third cavity 511 is connected to the valve port 515. A guide port 516 is provided inside the third cavity 511, and the guide port 516 is located in the third cavity 511 on the side where the fourth spring 513 is located.

[0077] The first water outlet pressurization assembly includes a fourth cavity 521 disposed inside the air valve sleeve 722, a fourth pressurization rod 522 slidably disposed inside the fourth cavity 521, an opening groove 523 disposed above the middle part of the fourth pressurization rod 522, and a fifth spring 524 disposed in the fourth cavity 521 and inserted into the opening groove 523. A sealing plate 525 is provided above the fourth pressurization rod 522. A fourth sealing ring 526 is embedded on the outer ring surface of the sealing plate 525. The fourth sealing ring 526 abuts against the inner side wall of the fourth cavity 521. The fourth cavity 521 is connected to the third cavity 511 above through the guide port 516.

[0078] The first water outlet pressurization component also includes a guide sleeve 527 fixedly installed below the fourth pressurization rod 522. The guide sleeve 527 is provided with a switching channel 528. The fourth pressurization rod 522 drives the guide sleeve 527 to slide up and down to switch the water flow state of the switching channel 528.

[0079] The fifth spring 524 is made of spring steel, with a length of 2cm and a spring cross-section thickness of 0.2mm. It can increase the force by 15-30N and, through the second pressurization chamber, raise the water pressure of the pre-filled water flow by 1.2-1.5MPa. In this embodiment, the first spring 414 can increase the force by 21N and, through the first pressurization chamber, raise the water pressure of the pre-filled water flow by 1.4-1.42MPa.

[0080] The second water outlet pressurization assembly includes a fifth cavity 531 extending downward from the fourth cavity 521, a fifth pressurization rod 532 slidably disposed inside the fifth cavity 531, and a sixth spring 533 installed on the outer ring surface below the fifth pressurization rod 532. The fifth pressurization rod 532 is located below the fourth pressurization rod 522, and the fourth pressurization rod 522 passes through the fifth pressurization rod 532 from top to bottom. The fourth cavity 521 is connected to the fifth cavity 531, and the side of the fifth cavity 531 is connected to the second inner cavity 421.

[0081] The fifth cavity 531 is narrower than the fourth cavity 521, and an inwardly inclined portion is provided inside the fifth cavity 531. The outer side of the fifth booster rod 532 is in contact with the inclined portion inside the fifth cavity 531.

[0082] The sixth spring 533 is made of spring steel, with a length of 0.5 cm and a spring cross-section thickness of 0.3 mm. It can increase the force by 3-5 N and raise the water pressure of the water flow by 0.2-0.4 MPa. In this embodiment, the first spring 414 can increase the force by 4 N, and through the first pressurization chamber, it can raise the water pressure of the pre-charged water flow by 0.31-0.34 MPa.

[0083] In the initial state, the fourth booster rod 522 is pulled by the fifth spring 524, and the lower part of the fourth booster rod 522 is pressed against the fifth booster rod 532. At the same time, the sixth spring 533 is compressed by the fifth booster rod 532, and the fifth cavity 531 is separated from the fourth cavity 521 by the contact with the inclined part.

[0084] During the pressurization process in the second inner cavity 421, water flows into the fifth cavity 531. As the water pressure increases, it gradually lifts the fifth pressurizing rod 532, making the fifth cavity 531 and the fourth cavity 521 connected. The water flow is then directed into the fourth cavity 521 below the fourth pressurizing rod 522. As the water flow continues, the water pressure increases, causing the fourth pressurizing rod 522 to move the guide sleeve 527 upward in the fourth cavity 521. At the same time, the fourth spring 513 and the fifth spring 524 are continuously stretched until the fourth pressurizing rod 522 is completely pressed against the top of the fourth cavity 521 and cannot move.

[0085] During this process, the upper part of the fourth pressure rod 522 in the fourth cavity 521 is always connected to the third cavity 511 through the guide port 516. Therefore, as the fourth pressure rod 522 moves upward, the internal pressure of the third cavity 511 continuously increases, causing the third pressure rod 512 to move outward, while the fourth spring 513 is also continuously stretched and extended.

[0086] To maximize the upward stroke of the fourth booster rod 522, a guide groove is provided on the side of the fourth booster rod 522 to connect the fifth cavity 531 and the fourth cavity 521. During the upward movement of the fourth booster rod 522, after the pressure in the third cavity 511 reaches its upper limit, water can be introduced into the upper part of the fourth cavity 521. Therefore, the stroke of the fourth booster rod 522 can be ensured, and the third cavity 511 can be kept in a high-pressure holding state through the cooperation of the three.

[0087] The active switching mechanism includes a sixth cavity 61 disposed inside the air valve sleeve 722 and a switching rod 62 slidably installed inside the sixth cavity 61. A seventh spring 63 is sleeved in the middle of the switching rod 62. The switching rod 62 divides the sixth cavity 61 into an upper cavity and a lower cavity. One side of the upper cavity of the sixth cavity 61 is connected to the fifth cavity 531. A first connecting port 64 is provided above the sixth cavity 61. The sixth cavity 61 is connected to the first flushing pipe 31 through the first connecting port 64. The lower cavity of the sixth cavity 61 is connected to the switching channel 528. A second connecting port 65 is provided in the middle of the switching rod 62. A blocking part 66 is provided in the middle of the sixth cavity 61. The blocking part 66 blocks the second connecting port 65. The second connecting port 65 is connected to the second flushing pipe 32.

[0088] In normal conditions, when the conductive sleeve 527 moves completely upward, its bottom separates the communication channel between the sixth cavity 61 and the fifth cavity 531, making them unable to communicate.

[0089] In normal conditions, the sixth booster rod blocks the second connecting port 65 with the sealing part 66, and the second connecting port 65 and the second flushing pipe 32 are in a state of being unable to communicate.

[0090] When the push rod 725 opens the valve cover 724, allowing the third chamber 511 to be fully pressed down, the third pressure rod 512 gradually returns to its original position under the traction of the fourth spring 513. At the same time, the pressure above the fourth chamber 521 is released, allowing the fourth pressure rod 522 to move downwards gradually under the traction of the fifth spring 524. This pressurizes the water in the fourth chamber 521, causing it to re-enter the fifth chamber 531.

[0091] At the same time, the sixth spring 533 ejects the fifth booster rod 532 outward, and its elastic force keeps the fifth booster rod 532 in the ejected state;

[0092] like Figure 6-8 As shown, during the downward movement of the fourth booster rod 522, the guide sleeve 527 is moved downward, and the fifth cavity 531 and the sixth cavity 61 are reconnected, allowing the water to be discharged through the first flush pipe 31 immediately. The water pressure is at its highest at this time due to the multi-stage boosting, and it can be connected to the upper flushing part of the toilet through the first flush pipe 31 to achieve boosted flushing.

[0093] like Figure 9-11 As shown, as the guide sleeve 527 continues to move downward, its switching channel 528 connects with the fifth cavity 531. Water flows through the switching channel 528 into the lower cavity of the sixth cavity 61, pushing the switching rod 62 upward, causing the sealing part 66 to be misaligned with the second connecting port 65, thereby connecting the second connecting port 65 with the second flushing pipe 32. The second flushing pipe 32 can connect to the toilet drain. Water flows through the second flushing pipe 32 into the toilet drain, which can form a negative pressure siphon effect, allowing for the first flush and emptying of the sewage in the toilet.

[0094] like Figure 6 As shown in the water outlet state, as the guide sleeve 527 continues to move downward, the switching channel 528 is closed again. Therefore, the sixth booster rod, which has lost its thrust, is reset under the traction of the seventh spring 63, while the second connecting port 65 is blocked again, the second flushing pipe 32 is closed again, and the first water outlet pipe 3 resumes the water outlet state and resumes water outlet, forming a water seal state.

[0095] With the above combination, even with low water pressure, a good flushing effect can be achieved even with an external water supply pressure as low as 0.08 MPa.

[0096] The above describes the flushing state during a single operation of the valve body. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
