[0043] Please refer to Figures 1 to 5 The first aspect of the present application provides a waterway scouring switching device, comprising:

[0044] The shell 1 has a first cavity 2, a first water inlet 3, a first water outlet 4 and a second water outlet 5, the first water inlet 3, the first water outlet 4 and the second water outlet 5 are communicated with the first cavity 2, the first water inlet 3 is used to introduce liquid into the first cavity 2, and the first water outlet 4 is located above the second water outlet 5;

[0045] The movable body 6 has a counterweight groove 8 which is in communication with the first cavity 2, and the movable body 6 is movably arranged in the first cavity 2, so that the movable body 6 has a first position and a second position, the first position is above the second position, in the first position, the movable body 6 can cover at least part of the first water outlet 4, and the movable body 6 is driven to move upward to the first position by the reset member and is limited in the first position; in the second position, the movable body 6 can cover at least part of the second water outlet 5, and the movable body 6 is driven to move downward by the gravity of the liquid filled in the counterweight groove 8.

[0046] The reset member is arranged in the first cavity 2, and the reset member is used to drive the movable body 6 to reset upward, and the upward force of the reset member is less than the gravity of the liquid filled in the counterweight groove 8.

[0047] First, the functions of each component are introduced:

[0048] The shell 1 is provided with a first cavity 2, a first water inlet 3, a first water outlet 4 and a second water outlet 5, wherein the first cavity 2 serves as the main container of the liquid and is also the moving area of the movable body 6; the first water inlet 3 is used to introduce liquid into the first cavity 2, the first water outlet 4 serves as the liquid discharge port when the movable body 6 is in the second position; the second water outlet 5 serves as the liquid discharge port when the movable body 6 is in the first position.

[0049] The movable body 6 has a counterweight groove 8, wherein the counterweight groove 8 is in communication with the first cavity 2, and the counterweight groove 8 is mainly used for water inlet and water outlet, when the liquid enters the counterweight groove 8, it will generate a downward gravity to the movable body 6, so that the movable body 6 has a downward moving tendency; the movable body 6 is fixed or moved between the first position and the second position according to the pressure difference between the inside of the first cavity 2 and the first water outlet 4 or the second water outlet 5 when the first cavity 2 is filled with water, the upward force of the reset member and the gravity of the liquid filled in the counterweight groove 8; in the first position, the movable body 6 can cover at least part of the first water outlet 4 to prevent most of the liquid from flowing out of the first water outlet 4; in the second position, the movable body 6 can cover the second water outlet 5 to prevent most of the liquid from flowing out of the second water outlet 5.

[0050] The reset member is a component connecting the bottom of the shell 1 and the movable body 6, which has an upward force, and is mainly used to drive the movable body 6 to move upward by the upward force, so that the movable body 6 can move upward to the first position, it should be noted that the upward force of the reset member is less than the gravity of the liquid filled in the counterweight groove 8.

[0051] Working principle:

[0052] In the initial state of the waterway flushing switching device, the movable body 6 is located at the top of the first cavity 2, i.e. the first position of the first cavity 2, and covers at least part of the first water outlet 4, because the upward force of the reset member is greater than the gravity of the counterweight groove 8 in the movable body 6. At this time, the toilet is in standby state, ready to respond to flushing instructions at any time.

[0053] When the user presses the flushing button or triggers the flushing mechanism, the water source rapidly flows into the first cavity 2 through the first water inlet 3 for the first time. Because the water outlet amount of the second water outlet 5 per unit time is less than the water inlet amount of the first cavity 2 per unit time, the first cavity 2 will gradually accumulate water during this period. When the water level in the first cavity 2 rises above the top of the counterweight groove 8 of the movable body 6, the water in the first cavity 2 will enter the counterweight groove 8. When the counterweight groove 8 is full of water, the water flow in the counterweight groove 8 and the water flow accumulated in the first cavity 2 will reach a state of equilibrium, so that the movable body 6 continues to maintain the first position and will not move downward due to the gravity of the water accumulated in the counterweight groove 8. Then, because the movable body 6 is in the first position at this time, the water accumulated in the first cavity 2 will form a pressure difference with the first water outlet 4, so that the movable body 6 can maintain the state of covering the first water outlet 4 by means of the pressure difference between the inside and outside of the first cavity 2 and the upward force of the reset member.

[0054] When the duration of the first water inlet of the first water inlet 3 reaches the set value, the first water inlet 3 stops water from entering the first cavity 2. At this time, the water in the first cavity 2 will continue to be discharged through the second water outlet 5, the water level in the first cavity 2 will begin to drop, the pressure difference will begin to decrease, and the equilibrium state between the water flow in the first cavity 2 and the water flow in the counterweight groove 8 will be broken. Since the counterweight groove 8 is still full of water, it is noted that the upward force of the reset member on the movable body 6 is less than the sum of the gravity of the movable body 6 itself and the gravity of the water accumulated in the counterweight groove 8. Therefore, the movable body 6 in the first position moves downward as a whole to the second position through the gravity of the water in the counterweight groove 8, and is inserted into the second water outlet 5, so that the bottom of the movable body 6 covers at least part of the second water outlet 5.

[0055] After a period of time after the water is stopped, the first water inlet 3 begins to perform the second water inlet to the first cavity 2. Since the movable body 6 is in the second position at this time, water will accumulate in the entire first cavity 2, forming a full pipe dynamic water flow above the movable body 6 and flowing out of the first water outlet 4. At this time, the full pipe dynamic water flow will form a new equilibrium state with the water flow in the counterweight groove 8. Since the movable body 6 is in the second position at this time, the water accumulated in the first cavity 2 will form a pressure difference with the second water outlet 5. Then, the movable body 6 overcomes the upward force of the reset member by means of this pressure difference, maintains the second position, and continues to cover the second water outlet 5.

[0056] When the duration of the second water inlet of the first water inlet 3 reaches the set value, the first water inlet 3 stops supplying water to the first cavity 2, at this time, the pressure difference decreases, the slow discharge of the liquid in the counterweight tank 8 at the bottom of the tank makes the gravity of the water in the counterweight tank 8 gradually decrease. When the gravity of the water in the counterweight tank 8 is less than the upward force of the reset member, the movable body 6 starts to move upward from the second position to the first position, and finally returns to the first position, and covers the first water outlet 4 again. At this time, the waterway flushing switching device returns to the initial state.

[0057] The embodiment realizes accurate switching of the water outlet by setting the counterweight tank 8 in the movable body 6, without relying on the pulse valve which is easily affected by water pressure. The movable body 6 can switch the waterway between the first position and the second position, ensuring the stability and reliability of the flushing process. The design of the reset member enables the movable body 6 to automatically reset after completing the flushing, improving the automation degree of the waterway switching. In addition, the flushing switching structure is simple, easy to manufacture and maintain, and has low cost. It is not affected by water pressure fluctuations and can always maintain stable flushing force, greatly improving the user experience and the cleanliness of the bathroom.

[0058] In an optional embodiment, the movable body 6 and the counterweight tank 8 are integrally formed.

[0059] In the embodiment, the integrally formed setting of the movable body 6 and the counterweight tank 8 means that the connection between the movable body 6 and the counterweight tank 8 is a non-detachable connection, such as integrally injection molding, which is not limited here. The connection between the movable body 6 and the counterweight tank 8 avoids the problems of loose, disengagement and poor sealing of the movable body 6 caused by the buoyancy and pressure of part of the water, and also avoids potential leakage risks, improves the sealing performance of the movable body 6 in the first cavity 2, and also simplifies the manufacturing process and reduces the assembly steps.

[0060] In an optional embodiment, the movable body 6 includes a guide portion 12 and an inner column 7;

[0061] The counterweight tank 8 is arranged between the guide portion 12 and the inner column 7;

[0062] The inner column 7 is arranged in the middle of the counterweight tank 8, and the inner column 7 is connected to the reset member;

[0063] The guide portion 12 is arranged outside the counterweight tank 8 and is in sliding connection with the first cavity 2.

[0064] In the embodiment, a specific implementation of the movable body 6 is provided, in which the movable body 6 includes the guide part 12 and the inner column 7, and the counterweight groove 8 is arranged between the guide part 12 and the inner column 7, and the inner column 7 is connected to the guide part 12 through the counterweight groove 8. When the waterway scouring switching device is started, the pressure difference between the dynamic water in the first cavity 2 and the first water outlet 4 or the second water outlet 5, the upward force of the reset member, and the gravity of the water in the counterweight groove 8 act on the movable body 6, so that the inner column 7 cooperates with the guide part 12 to be fixed in position or move up and down in the first cavity 2.

[0065] Specifically, when the first water inlet 3 first enters water, the water enters the first cavity 2 along the outer wall of the guide part 12. Since the water outlet amount of the second water outlet 5 per unit time is less than the water inlet amount of the first cavity 2 per unit time, the movable body 6 is limited in the first position by the pressure difference between the inside and outside of the water and the upward force of the reset member on the inner column 7 in the state of being filled with liquid in the first cavity 2, and covers the first water outlet 4. When the first water inlet 3 first stops supplying water to the first cavity 2, the pressure difference between the inside and outside of the first cavity 2 disappears, and the hydrologic balance state formed by the water flow in the first cavity 2 and the water flow in the counterweight groove 8 is broken. Therefore, the movable body 6 at the first position overcomes the upward force of the reset member connected to the inner column 7 by the gravity of the liquid filled in the counterweight groove 8, and moves to the second position in the first cavity 2 through the structure of the guide part 12, and abuts against the second water outlet 5. When the first water inlet 3 stops supplying water for the second time, the pressure difference decreases, and the bottom of the counterweight groove 8 arranged in the movable body 6 at the second position starts to drain water. When the gravity of the remaining liquid in the counterweight groove 8 starts to be less than the upward force of the reset member, the upward force of the reset member is transmitted to the entire movable body 6 through the inner column 7, and then the entire movable body 6 is moved to the first position according to the structure of the guide part 12.

[0066] In actual application, the clever cooperation between the guide part 12, the inner column 7 and the counterweight groove 8 provides a strong guarantee for the accurate movement of the movable body 6 in the first cavity 2. The guide part 12 not only can realize water diversion, but also can serve as a moving guide rail of the movable body 6. Through the close cooperation of the reset member and the inner column 7, the position of the movable body 6 is accurately controlled. The design of the counterweight groove 8 enables the inner column 7 to stably stay at the preset first or second position according to the upward force of the reset member and the gravity of the liquid in the counterweight groove 8, thereby improving the operation reliability of the waterway scouring switching device, and significantly enhancing the stability and response speed of the waterway scouring switching device.

[0067] In an optional embodiment, the inner column 7 is provided with the cover plate 10 and the extension part 11.

[0068] The cover plate 10 is arranged at the top of the inner column 7 and faces the first water outlet 4, and the outer diameter of the cover plate 10 is greater than the inner diameter of the first water outlet 4, so that the cover plate 10 covers the first water outlet 4 in the first position;

[0069] The extension 11 is arranged at the bottom of the inner column 7 and faces the second water outlet 5, and the outer diameter of the extension 11 is smaller than the inner diameter of the second water outlet 5, so that the extension 11 is inserted into the second water outlet 5 to cover the second water outlet 5 in the second position.

[0070] In this embodiment, a specific implementation of the inner column 7 is provided, in which the inner column 7 is provided with a cover plate 10 and an extension 11. The cover plate 10 is arranged at the top of the inner column 7 and faces the first water outlet 4, and the extension 11 is arranged at the bottom of the inner column 7 and faces the second water outlet 5. When the first cavity 2 is filled with water for the first time, the pressure difference between the inside of the first cavity 2 and the outside of the first water outlet 4 will restrict the movable body 6 in the first position. Then, the movable body 6 applies an upward pressure to the lower end surface of the cover plate 10 by means of the pressure difference. Since the extension 11 is connected to the return member, the return member also applies an upward force to the inner column 7 through the extension 11. Therefore, the inner column 7 remains in the first position and covers the first water outlet 4 under the upward force of the return member and the upward pressure of the cover plate 10. Since the outer diameter of the cover plate 10 is greater than the inner diameter of the first water outlet 4, the cover plate 10 can cover the first water outlet 4, preventing liquid leakage caused by waterway scouring.

[0071] When the first cavity 2 is filled with water for the second time, the pressure difference between the inside of the first cavity 2 and the outside of the second water outlet 5 will restrict the movable body 6 in the second position. Then, the movable body 6 applies a downward pressure to the upper end surface of the cover plate 10 by means of the pressure difference. Since the inner column 7 is arranged in the counterweight groove 8, the liquid in the first cavity 2 will also supplement the liquid in the counterweight groove 8. Therefore, the counterweight groove 8 remains in the second position by overcoming the operation of the return member downward. Since the outer diameter of the extension 11 is smaller than the inner diameter of the second water outlet 5, the inner column 7 can insert into the second water outlet 5 through the extension 11 to cover the second water outlet 5. This design improves the sealing of the waterway scouring and also achieves accurate control of different water outlets.

[0072] In an optional embodiment, the counterweight groove 8 is provided with a second water inlet 13 and a delayed water outlet hole 14;

[0073] The second water inlet 13 is arranged at the top of the counterweight groove 8 and faces the first water outlet 4, and the first cavity 2 communicates with the counterweight groove 8 through the second water inlet 13 and the delayed water outlet hole 14;

[0074] The delayed water outlet hole 14 is arranged at the bottom of the counterweight tank 8, and is used to delay the flow rate of the liquid in the counterweight tank 8.

[0075] In this embodiment, a specific implementation of the counterweight tank 8 is provided, in which the counterweight tank 8 is provided with a second water inlet 13 and a delayed water outlet hole 14. The second water inlet 13 is located at the top of the counterweight tank 8 and faces the first water outlet 4. When the first water inlet 3 introduces liquid into the first cavity 2, and the liquid level in the first cavity 2 rises to exceed the top end of the guide portion 12 of the movable body 6, the water in the first cavity 2 will enter the counterweight tank 8 through the second water inlet 13. Since the bottom of the counterweight tank 8 is provided with a delayed water outlet hole 14, the area of the delayed water outlet hole 14 is small, so when the first cavity 2 is filled with water, the water will also enter the counterweight tank 8 through the delayed water outlet hole 14. Since the area of the delayed water outlet hole is small, only a small amount of water slowly enters the counterweight tank 8 before the water level in the first cavity 2 rises to the top end of the movable body 6, so the water entering the counterweight tank 8 through the delayed water outlet hole 14 will not affect the overall waterway switching operation. When the first water inlet 3 is filled with water for the second time, since the movable body 6 is located at the second position, a full pipe dynamic water flow will appear above the second water inlet 13, which will form a new hydrologic balance state with the water flow in the counterweight tank 8, and the water above the second water inlet 13 will exert a downward water pressure on the upper end surface of the cover plate 10 and the counterweight tank 8, so that the counterweight tank 8 can continue to overcome the overall upward force of the return member, so that the movable body 6 can continue to maintain at the second position. When the second filling of the first water inlet 3 is completed, the liquid in the counterweight tank 8 will not immediately flow out, but will be limited by the delayed water outlet hole 14 and slowly discharged. This design ensures that the counterweight tank 8 can maintain a certain amount of liquid for a period of time, thereby maintaining the downward pressure on the movable body 6. As the liquid is gradually discharged, the gravity of the liquid in the counterweight tank 8 gradually decreases, and when the gravity is less than the upward force of the return member, the return member will drive the movable body 6 to move upward and eventually return to the first position, covering the first water outlet 4. It should be noted that the size of the delayed water outlet hole 14 can be set according to actual conditions, and is not limited herein.

[0076] In practical applications, through the second water inlet 13, the counterweight tank 8 can effectively receive liquid from the first cavity 2, and the setting of the delayed water outlet hole 14 ensures that the liquid in the counterweight tank 8 will not be quickly discharged. This design not only maintains the amount of liquid in the counterweight tank 8 for a period of time, providing a stable gravity for the movable body 6, but also delays the flow rate of the liquid, achieving stable switching of the movable body 6 between the two positions, enhancing the reliability and operation stability of the waterway flushing switching device, and improving the efficiency and accuracy of the overall waterway switching.

[0077] In an alternative embodiment, the guide portion 12 is provided with a plurality of guide posts 15, and the inner post 7 is slidably arranged in the first cavity 2 through the guide posts 15.

[0078] In this embodiment, a specific implementation of the up-and-down movement of the guide post 15 is provided. The guide portion 12 is externally provided with a plurality of guide posts 15, and the number of the guide posts 15 is not specifically limited. The main function of the guide post 15 is to provide strong support for the stable up-and-down sliding of the entire movable body 6 in the first cavity 2, to ensure that the movable body 6 can smoothly move along the predetermined track through the guide post 15, and to enhance the connection stability between the entire movable body 6 and the first cavity 2. The design of the guide post 15 enables the movable body 6 to maintain accurate positioning during the sliding process, avoiding the influence of deviation or shaking on the normal operation of the waterway switching device. At the same time, the slidable design also makes the up-and-down movement of the movable body 6 more flexible and reliable during the operation of the device, improving the stability of the entire waterway flushing switching device.

[0079] In an alternative embodiment, the housing 1 comprises a first housing 16 and a second housing 17, the opening of the first housing 16 faces the lower side, the opening of the second housing 17 faces the upper side, the second housing 17 and the first housing 16 define the first cavity 2, the second housing 17 and the first housing 16 are connected through a buckle 18, a sealing ring 19 is arranged between the second housing 17 and the first housing 16, the first water inlet 3 and the first water outlet 4 are arranged on the first housing 16, and the second water outlet 5 is arranged on the second housing 17.

[0080] In this embodiment, a specific implementation of the housing 1 is provided.

In this implementation, the reset member is in the form of an elastic member 20, which is fixed at the bottom of the second water outlet channel 24 and sleeved at the top of the extension 11. When the liquid in the counterweight groove 8 has a greater gravitational force than the upward force of the elastic member 20, the elastic member 20 will be compressed downward and store elastic potential energy. Once the liquid in the counterweight groove 8 flows out, the elastic member 20 will use the stored elastic potential energy to push the extension 11 upward. Since the extension 11 is arranged at the bottom of the inner column 7, which is integrally formed with the counterweight groove 8, the elastic member 20 will push the inner column 7 and the counterweight groove 8 to move upward together by pushing the extension 11. At the same time, the guide ability of the guide column 15 ensures that the counterweight groove 8 and the inner column 7 can be stably and accurately reset to the first position during the upward movement of the extension 11.
