[0042] To address the aforementioned technical problems, this application provides a mechanical switching valve flushing device for use in the sanitary ware industry. By incorporating a baffle plate, under water pressure, the baffle plate can move away from the movable frame and downwards to block the first outlet, allowing water to be discharged from the second outlet at a higher pressure. This prevents water flow dispersion, thereby increasing the water pressure during flushing and enabling a more thorough flushing of the toilet interior, ensuring the toilet remains clean and tidy.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] Please see Figure 1 and Figure 6 A mechanical switching valve flushing device includes: an inlet component 01, a limiting component 02, and an outlet component 03;

[0049] The limiting component 02 includes: a limiting member 021, a movable frame 022, and a water-blocking plate 023;

[0050] The water inlet assembly 01 is provided with a first water outlet 011;

[0051] The limiting member 021 is disposed within the movable frame 022;

[0052] The water baffle 023 is connected to the movable frame 022, and the water baffle 023 is connected to one end of the first water outlet 011;

[0053] One end of the mobile frame 022 is connected to the water outlet assembly 03;

[0054] The water inlet assembly 01 is connected to the water outlet assembly 03;

[0055] The water inlet assembly 01 is used to connect to a water source, and the first water outlet 011 is used to discharge the water in the water inlet assembly 01 through the first water outlet 011. The water inlet assembly 01 and the water outlet assembly 03 are connected to form a water storage cavity. The movable frame 022 is movably disposed in the water storage cavity and is used to drive the water baffle 023 to move. The water baffle 023 is used to block the first water outlet 011 under water pressure. The limiting member 021 is used to limit the movement distance of the movable frame 022 in the water storage cavity. The water outlet assembly 03 is used to discharge the water in the water storage cavity.

[0056] In the initial state, the movable frame 022 is located at a specific position within the water storage cavity, and the limiting member 021 pre-limits the movement range of the movable frame 022. The baffle plate 023 is tightly connected to the movable frame 022, and there is a certain gap between the baffle plate 023 and the first outlet 011 when the water pressure does not change significantly. The water inlet assembly 01 is connected to the water source, and the water flows from the water inlet assembly 01 into the cavity formed by the connection of the water inlet assembly 01 and the water outlet assembly 03. The movable frame 022 is located within the cavity. When the water flows into the cavity, it pushes the movable frame 022 forward. Because the movable frame 022 moves forward, a certain gap is created between the movable frame 022 and the baffle plate 023. Under the action of water pressure, the baffle plate 023 moves downward and blocks the first outlet 011. The water outlet assembly 03 has a groove that mates with the limiting member 021. When the movable frame 022 moves forward a certain distance, the limiting member 021 engages in the groove, limiting the movable frame 022. Water flows out through the water outlet assembly 03 to flush the toilet. When the water supply stops, the water pressure decreases, and the reset member inside the water outlet assembly 03 pushes the movable frame 022 back to its initial position. At this time, the water baffle 023, driven by the movable frame 022, returns to its initial state, releasing the blockage of the first water outlet 011. The water storage chamber is now filled with water. When the movable frame 022 resets, the water inside the movable frame 022 generates buoyancy, lifting the limiting member 021. At this point, according to the preset program, a second flush is performed. Water flows back into the water storage chamber, and the movable frame 022 moves forward under water pressure. The limiting member 021 is lifted by buoyancy. When the movable frame 022 moves to the groove position, the limiting member 021 is higher than the groove and cannot be locked into it. The movable frame 022 continues to move forward, blocking the water outlet component 03. The water baffle 023 is driven by the movable frame 022, maintaining a certain distance from the first water outlet 011. Because the water outlet component 03 is blocked, water flows out through the first water outlet 011, performing a second flush on the toilet.

[0057] As can be seen from the above embodiments, the beneficial effects of this solution are as follows: This device realizes a two-stage flushing process for the toilet. During the first flush, the water flow from the water outlet component 03 uses strong force to quickly remove most of the main waste in the toilet, ensuring basic cleanliness inside the toilet. Subsequently, after the water supply stops flowing in, the reset component pushes the movable frame 022 to reset, causing the baffle plate 023 to release the blockage of the first water outlet 011. During the second flush, the limiting component 021 floats up due to buoyancy. At this time, the water flow re-enters the water storage cavity, pushing the movable frame 022 to move. After the limiting component 021 floats up, it cannot be locked in the groove to limit the movable frame 022. The movable frame 022 moves forward and blocks the water outlet component 03. The gap between the first water outlet 011 and the baffle plate 023 increases, allowing a larger water flow to be discharged from the first water outlet 011 for a second flush of the toilet. The second flush further cleans any remaining stains in the toilet bowl, thoroughly removing fine dirt still adhering to the toilet walls and corners after the first flush. This significantly improves the cleanliness of the toilet and effectively solves the problem of traditional toilets being difficult to clean thoroughly with a single flush. During the first flush, the moving frame 022 moves, and the baffle plate 23 blocks the first water outlet 011, concentrating the water flow from the water outlet assembly 03. This allows for targeted cleaning of areas with concentrated dirt, enhancing the removal of stubborn stains. During the second flush, the water flows out from the first water outlet 011, providing a second cleaning of the entire toilet bowl, ensuring effective rinsing of all parts and combining precision and comprehensiveness in flushing. The device can automatically switch water flow paths according to a preset program, from initial flushing from the second water outlet to powerful flushing from the first water outlet, achieving control over the water flow path and meeting the needs of different flushing stages.

[0058] Please see Figure 1 , Figure 4 , Figure 6 as well as Figure 9 In an optional embodiment, the water inlet assembly 01 includes: a water inlet housing 012, a water inlet pipe 013, a first connecting part 014, and a second connecting part 015;

[0059] The first connecting part 014 is disposed at one end of the water inlet housing 012;

[0060] The water inlet pipe 013 is connected to the water inlet housing 012 through the first connecting part 014;

[0061] The second connecting part 015 is disposed at the other end of the water inlet housing 012 and is connected to the water outlet assembly 03.

[0062] The water inlet pipe 013 is provided with a connecting buckle, and the first connecting part 014 is provided with a connecting port corresponding to the connecting buckle.

[0063] The inlet housing 012, as the main structure of the inlet assembly 01, serves to install and protect other components. A first connecting part 014 is located on one side of the inlet housing 012, and it has a connection port corresponding to the connecting clip on the inlet pipe 013. The inlet pipe 013 connects to the inlet housing 012 by inserting the connecting clip into the connection port on the first connecting part 014. This connection method is convenient and quick, facilitating the replacement of the inlet pipe 013. A second connecting part 015 is located at the other end of the inlet housing 012 and is used to connect to the outlet assembly 03, thereby combining the inlet assembly 01 and the outlet assembly 03 into a water storage chamber. This allows water to enter the inlet housing 012 from the inlet pipe 013, and then flow to the outlet assembly 03 through the connection channel, ultimately achieving functions such as flushing the mechanical switching valve. The entire inlet assembly 01, through the above-described connection structure, ensures reliable connections between components and guarantees smooth water flow.

[0064] As can be seen from the above embodiments, the beneficial effects of this solution are as follows: The mechanical switching valve device provided in this application, by setting a connecting buckle on the water inlet pipe 013 and setting a corresponding connection port on the first connecting part 014, adopts the cooperation method of buckle and connection port, making the installation process of water inlet pipe 013 and water inlet housing 012 simple and quick, and facilitating equipment updates and maintenance. During normal use, this connection method can effectively prevent the water inlet pipe 013 from falling off from the water inlet housing 012, ensuring the stability and continuity of water flow transmission, and reducing the probability of malfunctions such as water leakage caused by connection problems. The water inlet pipe 013 and water inlet housing 012 adopt a detachable connection method. When the water inlet pipe 013 or water inlet housing 012 is damaged, it can be easily replaced individually without the need for large-scale disassembly or replacement of the entire water inlet assembly 01, reducing maintenance costs and difficulty, and extending the service life of the equipment.

[0065] Please see Figure 3 In an optional embodiment, the water-blocking plate 023 includes: a first guide post 0231, a second guide post 0232, and a return boss 0233;

[0066] The first guide post 0231 is disposed at one end of the water baffle 023, and the second guide post 0232 is disposed at the other end of the water baffle 023;

[0067] The return boss 0233 is disposed on the water baffle 023.

[0068] The movable frame 022 is provided with a first guide groove 0221 corresponding to the first guide column 0231 and a second guide groove 0222 corresponding to the second guide column 0232;

[0069] The movable frame 022 has a return groove 0223 corresponding to the return boss 0233, which is used to limit the water baffle 023.

[0070] In the initial state of the device, the baffle plate 023 is in a specific position. The first guide post 0231 at one end of the baffle plate 023 is embedded in the first guide groove 0221 on the moving frame 022, and the second guide post 0232 at the other end is embedded in the second guide groove 0222. Simultaneously, the return boss 0233 on the baffle plate 023 engages with the return groove 0223 on the moving frame 022. At this time, there is a certain gap between the baffle plate 023 and the first outlet 011. The first outlet 011 is not blocked, but since the water source has not yet been turned on, the water flow has not begun. The cooperation between the guide post and the guide groove ensures the stability of the baffle plate 023 in its initial position, preventing it from swaying randomly; the cooperation between the return boss 0233 and the return groove 0223 further limits the position of the baffle plate 023, ensuring its accurate positioning in the initial state. When the water inlet assembly 01 is connected to the water source, water begins to flow into the cavity formed by the connection between the water inlet assembly 01 and the water outlet assembly 03. As the water continuously flows in, it exerts a pushing force on the movable frame 022, causing it to move forward. Since the first guide pin 0231 and the second guide pin 0232 are respectively embedded in the first guide groove 0221 and the second guide groove 0222, the water-blocking plate 023 moves along with the movable frame 022 as it moves forward. With the change in the relative position between the movable frame 022 and the water-blocking plate 023, under the action of water pressure, the water-blocking plate 023 begins to move downwards along the direction of the guide groove. The first guide pin 0231 slides within the first guide groove 0221, and the second guide pin 0232 slides within the second guide groove 0222, providing guidance for the movement of the water-blocking plate 023 and ensuring that it moves smoothly and accurately. The baffle plate 023 moves to the position blocking the first outlet 011, preventing water from flowing out of the first outlet 011. After the initial flushing is completed, the water supply stops entering the cavity, and as the water supply stops, the water pressure inside the cavity gradually decreases. The reset component inside the water outlet assembly 03 begins to function. Under the action of the reduced water pressure, the reset component pushes the moving frame 022 back to its initial position. During the reset process of the moving frame 022, the first guide column 0231 slides in the opposite direction in the first guide groove 0221, and the second guide column 0232 slides in the opposite direction in the second guide groove 0222, causing the baffle plate 023 to move upward. When the moving frame 022 returns to its initial position, the baffle plate 023 also returns to its initial state with the cooperation of the guide column and the guide groove, and the return boss 0233 re-engages into the return groove 0223, releasing the blockage of the first outlet 011. When the movable frame 022 resets, the water inside it generates buoyancy, lifting the limiting member 021. Then, according to the preset program, a second flush is performed. Water flows back into the water storage chamber, and the movable frame 022 moves forward under water pressure, blocking the water outlet assembly 03. The water baffle 023 is moved by the movable frame 022, maintaining a certain distance from the first water outlet 011. Water flows out through the first water outlet 011, performing a second flush on the toilet.

[0071] As can be seen from the above embodiments, the beneficial effects of this solution are as follows: The cooperation between the first guide column 0231 and the first guide groove 0221, and the second guide column 0232 and the second guide groove 0222, provides a downward guide for the movement of the baffle plate 023. During the process of the water flow pushing the moving frame 022 and thus moving the baffle plate 023, the guide column slides smoothly within the guide groove, ensuring that the baffle plate 023 can move according to the predetermined trajectory and direction, blocking the first outlet 011. This avoids problems such as deviation, jamming, or shaking of the baffle plate 023 during movement, improving the reliability of the baffle plate 023 in blocking the first outlet 011. This ensures that the water flow can be discharged from the second outlet during the first flush and from the first outlet 011 during the second flush, optimizing the flushing effect. The cooperation between the return boss 0233 and the return groove 0223 plays a crucial role in the resetting process of the baffle plate 023. When the reset component pushes the movable frame 022 to reset, the water baffle 023 moves upward under the action of the guide column and guide groove. The return boss 0233 can accurately engage in the return groove 0223, ensuring that the water baffle 023 returns to its initial position.

[0072] Please see Figure 8 In an optional embodiment, a third guide post 0234 is provided on the water baffle 023.

[0073] The movable frame 022 has a third guide groove 0224 corresponding to the third guide post 0234. The water baffle 023 is connected to the movable frame 022 by being embedded in the third guide groove 0224 through the third guide post 0234.

[0074] In the initial state of the device, the baffle plate 023 is in its initial position. The third guide post 0234 on the baffle plate 023 is embedded in the third guide groove 0224 on the movable frame 022, connecting the baffle plate 023 to the movable frame 022. There is a certain gap between the baffle plate 023 and the first outlet 011. The embedded connection between the third guide post 0234 and the third guide groove 0224 provides initial stable support for the baffle plate 023, ensuring that its position is accurate and it does not wobble arbitrarily in the initial state. When the water inlet component is connected to the water source, water begins to flow into the cavity formed by the connection between the water inlet component and the water outlet component. As the water flows in continuously, the water flow exerts a pushing force on the movable frame 022, causing the movable frame 022 to move forward. Since the baffle plate 023 is embedded in the third guide groove 0224 of the movable frame 022 through the third guide post 0234, the baffle plate 023 will move downward under the action of water pressure during the forward movement of the movable frame 022. Finally, the baffle plate 023 moves to the position of blocking the first water outlet 011, preventing water from flowing out of the first water outlet 011. When the moving frame 022 moves forward a certain distance, the limiting member 021 will engage with the corresponding groove on the water outlet assembly 03, limiting the moving frame 022 and preventing it from moving further. At this time, since the baffle plate has blocked the first water outlet 011, the water cannot flow out from that outlet and instead flows out through the water outlet assembly 03, performing the first flush of the toilet. After the first flush is completed, the water supply stops entering the cavity, and as the water supply stops, the water pressure in the cavity gradually decreases. The reset member set in the water outlet assembly 03 begins to function. Under the action of the reduced water pressure, the reset member pushes the moving frame 022 back to its initial position. During the reset process of the moving frame 022, the baffle plate 23 moves together with the moving frame 022, and the third guide rail 0234 slides in the opposite direction within the third guide rail groove 0224. When the movable frame 022 returns to its initial position, the water-blocking plate 023, in conjunction with the guide sliding structure, also returns to its initial state, releasing the blockage of the first water outlet 011. During the reset of the movable frame 022, the water inside generates buoyancy, lifting the limiting member 021. Then, according to the preset program, a secondary flush is performed. Water flows back into the water storage chamber, and the movable frame 022 moves forward under water pressure, blocking the water outlet assembly 03. The water-blocking plate 023, driven by the movable frame 022, maintains a certain distance from the first water outlet 011. Water flows out through the first water outlet 011, performing a secondary flush on the toilet.

[0075] As can be seen from the above embodiments, the beneficial effects of this solution are as follows: The cooperation between the third guide post 0234 and the third guide groove 0224 provides guidance for the downward movement of the baffle plate 023. During the operation of the device, whether the baffle plate 023 moves together with the moving frame 022 or slides relative to the moving frame 022 under water pressure, it can move along a predetermined trajectory, ensuring that the baffle plate 023 can accurately block the first outlet 011, so that the baffle plate 023 will not deviate during the movement, ensuring the relative positional accuracy between the baffle plate 023 and the first outlet 011, thereby improving reliability. The connection method of the third guide post 0234 embedded in the third guide groove 0224 enhances the firmness of the connection between the baffle plate 023 and the moving frame 022. Under frequent device operation and water pressure impact, this connection method can ensure that the baffle plate 023 will not easily fall off or shift, ensuring the overall structural stability of the device.

[0076] Please see Figure 1 , Figure 4 , Figure 6 as well as Figure 9 In an optional embodiment, the water outlet assembly 03 includes: a third connecting part 031, a second water outlet 032, and a return spring 033;

[0077] The third connecting part 031 is connected to the second connecting part 015;

[0078] The reset spring 033 is disposed in the third connecting part 031 and is connected to the movable frame 022.

[0079] The water outlet assembly 03 is connected to the second connecting part 015 via the third connecting part 031, forming a complete water storage cavity. A return spring 033 is installed inside the water outlet assembly 03, with one end connected to the movable frame 022. In its initial position, the movable frame 022 is in the unblocked first outlet 011 of the water inlet assembly 01. When water flows into the water storage cavity from the water inlet assembly 01, the movable frame 022 moves forward under water pressure and is limited by the limiting member 021. Driven by the movable frame 022, the water baffle 023 blocks the first outlet, and the water then flows out through the second outlet 032 for initial flushing. When the water inlet assembly 01 is connected to a water source and the water pressure gradually increases, the water pressure acts on the movable frame 022, pushing it towards the second outlet 032. The movement of the movable frame 022 causes the connected return spring 033 to deform, compressing it. After the first flush, the internal water pressure gradually decreases, and the return spring 033 returns to its initial state, generating an elastic restoring force opposite to the previous deformation direction. This elastic restoring force acts on the movable frame 022, pushing it to reset. The movement of the movable frame 022 causes the water baffle 023 to return to its original position, gradually releasing it from the blockage of the first outlet 011. As the movable frame 022 continues to move, the device returns to its initial state. During the reset, the water inside the movable frame 022 generates buoyancy, lifting the limiting member 021. A second flush is then performed according to the preset program, and the water flow re-enters the water storage chamber. Under water pressure, the movable frame 022 moves forward, blocking the water outlet assembly 03. The water baffle 023, driven by the movable frame 022, maintains a certain distance from the first outlet 011. Water flows out through the first outlet 011 to flush the toilet a second time.

[0080] As can be seen from the above embodiments, the beneficial effects of this solution are as follows: The reset spring 033 enables the device to automatically reset when the water pressure changes. When the flushing operation ends and the water inlet assembly 01 stops supplying water, the internal water pressure drops. The reset spring 033, with its own elastic restoring force, can push the movable frame 022 back to its initial position, thereby causing the baffle plate 023 to release the blockage of the first outlet 011, restoring the device to its initial state. A second flush is then performed, with water flowing out through the first outlet 011 to flush the toilet a second time. The reset spring 033 enables the movable frame 022 to automatically reset, simplifying the operation process and improving the automation level of the device.

[0081] Please see Figure 1 as well as Figure 6 In an optional embodiment, the first outlet is provided with a threaded connection.

[0082] By incorporating a threaded connection on the first outlet 011, it becomes easier to connect to external pipes or other related components. The threaded connection allows for the screwing of threaded parts into the threaded connection of the first outlet 011, achieving a tight connection and preventing leaks. This threaded connection method not only facilitates installation but also ensures a secure connection that can withstand certain water pressure and vibration.

[0083] As can be seen from the above embodiments, the beneficial effects of this solution are as follows: The threaded connection method is simple and intuitive; a tight connection can be achieved simply by screwing the component with the corresponding thread into the threaded connection part of the first outlet 011. The threaded connection effectively prevents water leakage through the tight engagement of the threads. During device operation, water pressure will exert a certain pressure on the connection, and the threaded connection can withstand this pressure, ensuring that the connection remains sealed at all times, avoiding device malfunctions or water waste due to leakage.

[0084] Please see Figure 2 as well as Figure 5 In an optional embodiment, a sealing gasket 024 is provided on the movable frame 022.

[0085] In the initial state, the first outlet 011 of the water inlet assembly 01 is in a drainable state. Water entering from the water inlet assembly 01 flows along the designed path and exits from the second outlet 032, providing initial flushing of the toilet. When the toilet flushes through the first outlet 011 according to a preset program, the water inlet assembly 01 connects to the water source, and the water pressure gradually increases. This water pressure acts on the movable frame 022, pushing it towards the second outlet 032. As the movable frame 022 moves, it gradually approaches and blocks the second outlet 032. At this point, water cannot exit from the second outlet 032, and a large amount of water is diverted into the first outlet 011. The presence of the sealing gasket 024 ensures that water does not leak from the second outlet 032 during this process, allowing the water to concentrate and enter the first outlet 011 for flushing the toilet.

[0086] As can be seen from the above embodiments, the beneficial effects of this solution are as follows: Through the synergistic effect of the sealing gasket 024 and the movable frame 022, when flushing is required from the first water outlet 011, the movable frame 022 can effectively block the second water outlet 032, causing the water flow to concentrate towards the first water outlet 011, significantly improving the flushing force and cleaning effect of the toilet. The sealing gasket 024 ensures that water will not leak from the second water outlet 032 during the water flow switching process, avoiding the problem of reduced flushing effect due to insufficient water pressure, and improving the sealing and reliability of the device. The device can automatically switch the water flow path according to the preset program, from initial flushing through the second water outlet 032 to powerful flushing through the first water outlet 011, achieving precise control of the water flow path and meeting the needs of different flushing stages.
