Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] See also Figures 1 to 5 In a first aspect, the present application provides a waterway flushing switching device, comprising:

[0044] A housing 1, wherein the housing 1 has a first cavity 2, a first water inlet 3, a first water outlet 4 and a second water outlet 5, wherein the first water inlet 3, the first water outlet 4 and the second water outlet 5 are all connected to 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] A movable body 6, wherein the movable body 6 has a counterweight groove 8, wherein the counterweight groove 8 is connected to 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, wherein the first position is located above the second position, and in the first position, the movable body 6 can cover at least a portion of the first water outlet 4, and the movable body 6 is driven to move upward to the first position by a reset member and is restricted to the first position; in the second position, the movable body 6 can cover at least a portion of the second water outlet 5, and the movable body 6 is driven to move downward by the gravity of the liquid in the counterweight groove 8;

[0046] A reset member is located in the first cavity 2 and is used to drive the movable body 6 to reset upwards. The upward force of the reset member is smaller than the gravity of the counterweight groove 8 filled with liquid.

[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 for liquid and is also the area where the movable body 6 moves; the first water inlet 3 is used to introduce liquid into the first cavity 2, and the first water outlet 4 serves as a liquid discharge port when the movable body 6 is in the second position; the second water outlet 5 serves as a 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 connected to the first cavity 2, and the counterweight groove 8 is mainly used for water intake and water discharge. When liquid enters the counterweight groove 8, it will generate downward gravity to the movable body 6, so that the movable body 6 has a tendency to move downward; the movable body 6 is fixed or moved between the first position and the second position according to the pressure difference between the interior and the first water outlet 4 or the second water outlet 5 generated when the first cavity 2 is full of 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. It has an upward force and is mainly used to drive the movable body 6 to move upward through 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 counterweight slot 8 filled with liquid.

[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, that is, the first position of the first cavity 2, because the upward force of the reset member is greater than the gravity of the counterweight groove 8 provided in the movable body 6, and covers at least part of the first water outlet 4. At this time, the toilet is in a standby state, ready to respond to the flushing command at any time.

[0053] When the user presses the flush button or triggers the flush mechanism, the water source quickly flows into the first cavity 2 through the first water inlet 3 for the first time. Since the water output of the second water outlet 5 per unit time is less than the water intake of the first cavity 2 per unit time, the first cavity 2 will gradually store water during this period. When the water level in the first cavity 2 rises to exceed 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 stored in the first cavity 2 will reach a water balance state, so that the movable body 6 continues to maintain the first position and will not move downward due to the gravity of the water stored in the counterweight groove 8. Then, since the movable body 6 is in the first position at this time, the water stored 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 with the help 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 intake at the first water inlet 3 reaches the set value, the first water inlet 3 stops intake of water into the first cavity 2. At this time, the water inside the first cavity 2 will continue to be discharged through the second water outlet 5, and the water level in the first cavity 2 begins to drop, the pressure difference begins to decrease, and the horizontal equilibrium state formed by the water flow stored in the first cavity 2 and the water flow in the counterweight groove 8 is broken. Since the counterweight groove 8 is still full of water, it should be 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 stored in the counterweight cavity 8. Therefore, the movable body 6 located at the first position moves downward to the second position as a whole 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 supply is cut off, the first water inlet 3 starts to intake water into the first cavity 2 for the second time. Since the movable body 6 is in the second position at this time, the water will fill the entire first cavity 2, and a full-tube dynamic water flow will be formed above the movable body 6, and flow out to the first water outlet 4. At this time, the full-tube dynamic water flow will form a new water balance 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 stored 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 part with the help of this pressure difference, remains in the second position, and continues to cover the second water outlet 5.

[0056] When the duration of the second water inlet 3 reaches the set value, the first water inlet 3 stops inletting water into the first cavity 2. At this time, the pressure difference decreases, and the bottom of the counterweight groove 8 slowly discharges the liquid in the groove downward, so that the gravity of the water in the counterweight groove 8 gradually decreases. When the gravity of the water in the counterweight groove 8 is less than the upward force of the reset member, the movable body 6 starts to move upward from the second position, and finally returns to the first position, and covers the first water outlet 4 again. At this point, the waterway flushing switching device returns to the initial state.

[0057] This embodiment realizes precise switching of the water outlet by setting a counterweight groove 8 in the movable body 6. Without relying on a pulse valve that is easily affected by water pressure, the movable body 6 can switch the water path between the first position and the second position, thereby ensuring the stability and reliability of the flushing process. The design of the reset member enables the movable body 6 to automatically reset after the flushing is completed, thereby improving the degree of automation of the water path switching. In addition, the flushing switching structure is simple, easy to manufacture and maintain, low in cost, and is not affected by water pressure fluctuations. It can always maintain a 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 slot 8 are integrally formed.

[0059] In the present embodiment, the movable body 6 and the counterweight slot 8 are integrally formed, which means that the connection between the movable body 6 and the counterweight slot 8 is a non-detachable connection, such as integral casting, which is not specifically limited here. The connection between the movable body 6 and the counterweight slot 8 avoids the problems of loosening, detachment and poor sealing of the movable body 6 due to the buoyancy and pressure of some 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 groove 8 is provided between the guide portion 12 and the inner column 7;

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

[0063] The guide portion 12 is disposed outside the counterweight groove 8 and is slidably connected to the first cavity 2 .

[0064] In this embodiment, a specific implementation of the movable body 6 is provided, in which the movable body 6 includes a guide portion 12 and an inner column 7, a counterweight groove 8 is provided between the guide portion 12 and the inner column 7, and the inner column 7 is connected to the guide portion 12 through the counterweight groove 8. When the waterway flushing 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 portion 12 to fix its position or move up and down in the first cavity 2.

[0065] Specifically, when the first water inlet 3 takes in water for the first time, the water will enter the first cavity 2 along the outer wall of the guide portion 12. Since the amount of water discharged by the second water outlet 5 per unit time is less than the amount of water taken in by the first cavity 2 per unit time, the movable body 6 is restricted to the first position under the action of the pressure difference between the inside and outside of the water and the upward force of the reset member on the inner column 7 when the first cavity 2 is filled with liquid, and the first water outlet 4 is sealed. When the first water inlet 3 stops supplying water to the first cavity 2 for the first time, the movable body 6 is affected by the disappearance of the pressure difference between the inside and outside of the first cavity 2, and the water flow filled in the first cavity 2 and the horizontal formed by the water flow in the counterweight groove 8 are The balanced state is broken, so the movable body 6 at the first position uses the gravity of the counterweight groove 8 filled with liquid to overcome the upward force of the reset piece connected to the inner column 7 and moves to the second position in the first cavity 2 through the structure of the guide part 12, against the second water outlet 5; when the first water inlet 3 stops taking in 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 begins to drain water, and when the gravity of the remaining liquid in the counterweight groove 8 begins to be less than the upward force of the reset piece, the upward force of the reset piece will be transmitted to the entire movable body 6 through the inner column 7, and then the entire movable body 6 will be moved to the first position according to the structure of the guide part 12.

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

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

[0068] The cover plate 10 is disposed on the top of the inner column 7 and faces the first water outlet 4. The outer diameter of the cover plate 10 is larger than the inner diameter of the first water outlet 4. Thus, in the first position, the cover plate 10 covers the first water outlet 4.

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

[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 provided at the top of the inner column 7 and faces the first water outlet 4, and the extension 11 is provided 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 formed between the inside of the first cavity 2 and the outside of the first water outlet 4 will limit the movable body 6 to the first position, and 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 reset member, the reset member will also apply an overall upward force to the inner column 7 through the extension 11. Therefore, the inner column 7 is maintained in the first position and covers the first water outlet 4 under the upward force of the reset member and the upward pressure of the cover plate 10 by the pressure difference. Since the outer diameter of the cover plate 10 is larger than the inner diameter of the first water outlet 4, the cover plate 10 can cover the first water outlet 4, thereby preventing the leakage of liquid from the waterway flushing switching device.

[0071] When the first cavity 2 is filled with water for the second time, the pressure difference formed between the inside of the first cavity 2 and the outside of the second water outlet 5 will limit the movable body 6 to the second position, and 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 replenish the counterweight groove 8 with liquid, so the counterweight groove 8 keeps downward to overcome the operation of the reset member and maintains in the second position. Since the outer diameter of the extension part 11 is smaller than the inner diameter of the second water outlet 5, the inner column 7 can be inserted into the second water outlet 5 through the extension part 11 to achieve the sealing of the second water outlet 5. This design improves the sealing of the water path flushing switching and also realizes accurate control of different water outlets.

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

[0073] The second water inlet 13 is disposed at the top of the counterweight groove 8 and faces the first water outlet 4. The first cavity 2 is connected to 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 groove 8 , and the delayed water outlet hole 14 is used to slow down the outflow speed of the liquid in the counterweight groove 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 14, wherein 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 water level in the first cavity 2 rises to exceed the top 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 a delayed water outlet 14 is provided at the bottom of the counterweight tank 8, and the area of ​​the delayed water outlet 14 is relatively small, when the first cavity 2 is storing water, water will also enter the counterweight tank 8 through the delayed water outlet 14. Since the area of ​​the delayed water outlet is relatively small, only a small part of the water slowly enters the counterweight tank 8 before the water level in the first cavity 2 rises to the top of the movable body 6. Therefore, the water entering the counterweight tank 8 through the delayed water outlet 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 in the second position, a full-tube dynamic water flow will appear above the second water inlet 13, and the full-tube dynamic water flow will form a new water balance state with the water flow in the counterweight groove 8, and the water exerts a downward positive pressure of water on the upper end surface of the cover plate 10 and the counterweight groove 8 above the second water inlet 13, so that the counterweight groove 8 can continue to overcome the overall upward force of the reset member, so that the movable body 6 continues to maintain the second position. When the first water inlet 3 is filled with water for the second time, the liquid in the counterweight groove 8 will not flow out immediately, but will be restricted by the delayed water outlet 14 and slowly discharged at a slower speed. This design ensures that the counterweight groove 8 can still 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 groove 8 gradually decreases. When this gravity is less than the upward force of the reset member, the reset member will drive the movable body 6 to move upward, and finally return to the first position to cover the first water outlet 4. It should be noted that, in addition to the above implementations, the size of the delayed water outlet hole 14 can also be set according to specific actual conditions, and no specific limitation is made here.

[0076] In practical applications, the counterweight tank 8 can effectively receive the liquid from the first cavity 2 through the second water inlet 13, and the setting of the delayed water outlet 14 ensures that the liquid in the counterweight tank 8 will not be quickly emptied. 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 realizes the stable switching of the movable body 6 between the two positions by delaying the liquid outflow speed, thereby enhancing the reliability and operational stability of the waterway flushing switching device and improving the efficiency and accuracy of the overall waterway switching.

[0077] In an optional embodiment, the guide portion 12 is provided with a plurality of guide columns 15 , and the inner column 7 is slidably disposed in the first cavity 2 via the guide columns 15 .

[0078] In the present embodiment, a specific implementation method for the up and down movement of the guide column 15 is provided, and a plurality of guide columns 15 are arranged on the outside of the guide portion 12, and the specific number of the guide columns 15 is not specifically limited herein. The main function of the guide column 15 is to provide strong support for the entire movable body 6 to slide up and down stably in the first cavity 2, and to ensure that the movable body 6 can move smoothly along the predetermined track through the guide column 15, and also to enhance the connection stability between the entire movable body 6 and the first cavity 2. The design of the guide column 15 enables the movable body 6 to maintain accurate positioning during the sliding process, avoiding the normal operation of the waterway switching device being affected by displacement or shaking. At the same time, this slidable design also makes the up and down movement of the movable body 6 during the operation of the device more flexible and reliable, thereby improving the stability of the entire waterway flushing switching device.
