[0039] Please refer to Figs. 1 to 4 The first aspect of the present application provides a waterway quick switching device, comprising:

[0040] A shell 1 has a cavity 2, a water inlet channel 3, a first water outlet channel 4 and a second water outlet channel 5, the water inlet channel 3, the first water outlet channel 4 and the second water outlet channel 5 all communicate with the cavity 2, and the water inlet channel 3 is used to pass liquid into the cavity 2;

[0041] A gas supplement channel 7 communicates with the cavity 2, is located below the water inlet channel 3 and above the second water outlet channel 5, and is used to increase the pressure of the cavity 2;

[0042] A switching assembly 6 is movably arranged in the cavity 2, so that the switching assembly 6 has a first position and a second position, the first position is above the second position, in the first position, the switching assembly 6 can cover at least part of the first water outlet channel 4; in the second position, the switching assembly 6 can cover at least part of the second water outlet channel 5, the pressure in the cavity 2 is enhanced through the gas supplement channel 7, so that the liquid in the cavity 2 is accelerated to be discharged from the second water outlet channel 5, so that the switching assembly 6 is switched from the first position to the second position by the gravity of the switching assembly 6 filled with liquid inside;

[0043] A reset member is located in the cavity 2 and arranged on the switching assembly 6, and is used to drive the switching assembly 6 to move upward to the first position, the upward force of the reset member on the switching assembly 6 is less than the gravity of the switching assembly 6 filled with liquid.

[0044] The functions of the components in this embodiment are described in detail as follows:

[0045] The shell 1 is provided with a cavity 2, a water inlet channel 3, a first water outlet channel 4 and a second water outlet channel 5. The cavity 2 serves as a main container for liquid and is also a moving area of the switching assembly 6. The water inlet channel 3 is used to introduce liquid into the cavity 2. When the switching assembly 6 is in the second position, the first water outlet channel 4 serves as a liquid discharge channel and is internally provided with an anti-siphon component. The anti-siphon component opens the air outlet by moving downward to break the negative pressure in the cavity 2 and prevent the water in the cavity 2 from flowing back to the water inlet channel 3. The second water outlet channel 5 serves as a liquid discharge port when the switching assembly 6 is in the first position.

[0046] The switching assembly 6 can move up and down in the cavity 2 and is internally provided with a water storage space and a component for sealing the first water outlet channel 4 and the second water outlet channel 5. When the switching assembly 6 is in the first position, the switching assembly 6 seals at least part of the first water outlet channel 4, allowing the liquid in the water inlet channel 3 to flow out through the second water outlet channel 5. When the switching assembly 6 is in the second position, the switching assembly 6 seals at least part of the second water outlet channel 5, allowing the liquid in the water inlet channel 3 to flow out through the first water outlet channel 4. It should be noted that when one of the water outlet channels is sealed by the switching assembly 6, part of the water in the sealed water outlet channel will flow out, and the sealing is not complete.

[0047] The air supplement channel 7 is arranged on the shell 1 below the water inlet channel 3 and above the second water outlet channel 5. When the water inlet channel 3 stops introducing liquid into the cavity 2 for the first time, the air supplement channel 7 supplements air to the cavity 2, increases the pressure of the cavity 2, and solves the phenomenon that the remaining liquid in the cavity 2 cannot be smoothly discharged from the second water outlet channel 5 due to the negative pressure in the cavity 2.

[0048] The reset member is located in the cavity 2 and arranged on the switching assembly 6, and is used to drive the switching assembly 6 to move upward to the first position. It should be noted that the upward force of the reset member on the switching assembly 6 is less than the gravity of the switching assembly 6 when it is filled with liquid.

[0049] Working principle:

[0050] In the initial state, the switching assembly 6 of the waterway quick switching device is located in the first position under the action of the reset member and seals at least part of the first water outlet channel 4, ensuring that if the water inlet channel 3 starts to introduce water, the water can be smoothly discharged from the cavity 2 to the second water outlet channel 5.

[0051] When the water inlet channel 3 first fills with water, the water will flow into the cavity 2 through the water inlet channel 3. Since the water outlet amount of the second water outlet channel 5 per unit time is less than the water inlet amount of the cavity 2 per unit time, the cavity 2 will gradually fill with water during this period. When the water level in the cavity 2 rises to exceed the top of the water storage space of the switching assembly 6, the water in the cavity 2 will enter the water storage space provided by the switching assembly 6. When the water storage space in the switching assembly 6 is filled with water, the water in the water storage space and the water stored in the cavity 2 reach a state of water balance, so that the switching assembly 6 remains in a state of sealing the first water outlet channel 4 by means of the pressure of the water stored in the cavity 2 and the upward force of the reset member.

[0052] When the first water inlet of the water inlet channel 3 lasts for a set value, the water inlet channel 3 stops filling water into the cavity 2, and the air supplement channel 7 introduces external air into the cavity 2 to increase the pressure in the cavity 2, solve the negative pressure situation in the cavity 2, and accelerate the water in the cavity 2 to be discharged from the second water outlet channel 5. Then, when the water in the cavity 2 is rapidly discharged, the pressure of the water stored in the cavity 2 on the switching assembly 6 will rapidly decrease and disappear. During this process, the water storage space in the switching assembly 6 is still in a state of being filled with water. Since the upward resetting force of the reset member on the switching assembly 6 is less than the sum of the gravity of the switching assembly 6 itself and the gravity of the water in the switching assembly 6, the switching assembly 6 moves downward as a whole to the second position by overcoming the upward force of the reset member by the gravity of the water in the water storage space, and seals at least part of the second water outlet channel 5.

[0053] During a period of time after the water is stopped, the water inlet channel 3 fills with water for the second time. The water first forms a full pipe dynamic flow at the upper end of the cavity 2, and is discharged through the first water outlet channel 4. At this time, since the switching assembly 6 is in the second position, its upper end surface is subjected to the water pressure of the full pipe dynamic flow. In this state, the water storage space in the switching assembly 6 will drain to the part of the second water outlet channel 5 that is not sealed, until the water is completely drained. Since the sum of the water pressure of the full pipe dynamic flow and the gravity of the switching assembly 6 is greater than the upward force of the reset member, the switching assembly 6 will remain in this second position.

[0054] When the second water inlet of the water inlet channel 3 reaches the set value, the water inlet channel 3 stops water inlet, the anti-siphon part in the first water outlet channel 4 is reset downward by its own weight, so as to open the air outlet in the first water outlet channel 4, thereby destroying the negative pressure in the cavity 2 connected with the area of the first water outlet channel 4, so that the remaining liquid in the cavity 2 continues to be discharged from the first water outlet channel 4, and the liquid in the cavity 2 is prevented from flowing back to the water inlet channel 3. Then, at this time, since the water in the water storage space of the switching assembly 6 has been discharged when the water inlet channel 3 is secondly water-inlet, the upward force of the reset part on the switching assembly 6 is greater than the gravity of the switching assembly 6 itself, so that the switching assembly 6 is reset upward to the first position under the action of the reset part, and the first water outlet channel 4 is covered, so as to prepare for the next water channel switching.

[0055] In actual application, at the moment when the water inlet channel 3 stops water inlet after the water outlet of the second water outlet channel 5, the cavity 2 is timely supplemented with air through the air supplement channel 7 to increase the pressure, so as to solve the phenomenon that the liquid in the cavity 2 cannot be smoothly discharged from the second water outlet channel 5 due to the negative pressure in the cavity 2, and the increase of the internal pressure of the cavity 2 can also accelerate the discharge of the remaining liquid in the cavity 2 from the second water outlet channel 5, so that the switching assembly 6 is switched from the first position to the second position by the gravity of the liquid filled in the switching assembly 6, and the switching assembly 6 in the second position does not affect the discharge of the liquid from the cavity 2 to the first water outlet channel 4 through the water inlet channel 3, so as to ensure the smoothness of the water channel switching.

[0056] In an optional embodiment, the shell 1 comprises a first shell 9, a second shell 10 and a third shell 11;

[0057] The first shell 9 is arranged on the top of the second shell 10, the third shell 11 is arranged on the bottom of the second shell 10, the third shell 11 and the second shell 10 define the cavity 2, the second shell 10 is arranged on the third shell 11 through the buckle 12, the first water outlet channel 4 is arranged on the first shell 9, the water inlet channel 3 and the air supplement channel 7 are arranged on the second shell 10, the second water outlet channel 5 is arranged on the third shell 11, the first sealing ring 13 is arranged between the first shell 9 and the second shell 10, and the second sealing ring 14 is arranged between the second shell 10 and the third shell 11.

[0058] In this embodiment, a specific implementation of the shell 1 is provided, in which the shell 1 includes a first shell 9, a second shell 10, and a third shell 11. The first shell 9 is arranged on the top of the second shell 10, providing protection and support for the waterway switching device on the top, and the first water outlet channel 4 arranged on the first shell 9 also facilitates the export of liquid. The second shell 10 serves as an intermediate connecting part, not only bearing the water inlet channel 3 and the air supplement channel 7, but also being tightly connected with the third shell 11 through the buckle 12, ensuring the sealing and stability of the cavity 2. The third shell 11 cooperates with the second shell 10 to define the cavity 2, providing space for the storage and flow of liquid. At the same time, the second water outlet channel 5 is arranged on the third shell 11, so that the liquid can also be smoothly discharged from the cavity 2 to the second water outlet channel 5. In actual application, this shell 1 design not only improves the overall strength and durability of the waterway switching device, but also facilitates the maintenance and replacement of various components.

[0059] Among them, the first sealing ring 13 and the second sealing ring 14 are arranged between the first shell 9 and the second shell 10, and between the second shell 10 and the third shell 11, respectively. The arrangement of the first sealing ring 13 and the second sealing ring 14 effectively enhances the sealing performance between the first shell 9, the second shell 10, and the third shell 11, preventing liquid from leaking from the gaps between the first shell 9, the second shell 10, and the third shell 11 during the flow in the cavity 2, and ensuring the reliability and safety of the waterway switching device. Moreover, as key sealing components, the first sealing ring 13 and the second sealing ring 14 can tightly fit the contact surfaces between the shells 1, forming an effective sealing barrier and prolonging the service life of the waterway switching device.

[0060] In an optional embodiment, the air supplement channel 7 is integrally formed with the second shell 10.

[0061] In this embodiment, the integrally formed arrangement of the air supplement channel 7 and the second shell 10 means that the connection between the air supplement channel 7 and the second shell 10 is a non-detachable connection, such as one-piece casting, which is not limited here. The connection between the air supplement channel 7 and the second shell 10 avoids problems such as looseness, falling off, or poor sealing that may be caused by component separation, also avoids potential leakage risks, improves the sealing performance of the waterway switching device, and simplifies the manufacturing process and reduces the assembly steps.

[0062] In an optional embodiment, the cavity 2 includes a first cavity 15, a second cavity 16, a first water passage 17, and a second water passage 18.

[0063] The water inlet channel 3, the first water passage 17 and the second water passage 18 are in communication with the first cavity 15; the second water passage 18, the air supplement channel 7 and the second water outlet channel 5 are in communication with the second cavity 16.

[0064] In the embodiment, a specific implementation of the cavity 2 is provided, which includes the first cavity 15, the second cavity 16, the first water passage 17 and the second water passage 18. When the water inlet channel 3 is first supplied with water, the water is first introduced into the first cavity 15 and forms a full-pipe dynamic water flow in the first cavity 15. Since the switching assembly 6 is located at the first position when the water is first supplied, the water in the first cavity 15 is introduced into the second cavity 16 through the second water passage 18, and then the water in the second cavity 16 is discharged through the second water outlet channel 5. Since the water discharge amount of the second water outlet channel 5 per unit time is less than the water intake amount of the second cavity 16 per unit time, the second cavity 16 begins to gradually accumulate water during this period until the second cavity 16 is filled. When the water inlet channel 3 is first stopped, the air supplement channel 7 introduces external air into the second cavity 16 to increase the pressure in the second cavity 16, so that the remaining liquid in the second cavity 16 is rapidly discharged to the second water outlet channel 5, solving the negative pressure in the second cavity 16. When the water inlet channel 3 is secondly supplied with water, the water is first introduced into the first cavity 15 and forms a full-pipe dynamic water flow in the first cavity 15. Since the switching assembly 6 is located at the second position when the water is secondly supplied, the water in the first cavity 15 flows to the first water outlet channel 4 through the first water passage 17.

[0065] In actual application, when the water is first discharged, the water inlet channel 3 introduces water into the first cavity 15, then the first cavity 15 introduces water into the second cavity 16 through the second water passage 18, and then the second cavity 16 flows the internal water into the second water outlet channel 5, completing the water discharge path from the water inlet channel 3 to the second water outlet channel 5. When the water is first stopped, the intervention of the air supplement channel 7 prevents the negative pressure in the second cavity 16 from causing the remaining liquid in the second cavity 16 to be unable to be discharged from the second water outlet channel 5. When the water is secondly supplied, the water flow in the first cavity 15 directly flows to the first water outlet channel 4 through the first water passage 17, realizing the on-demand switching of the water path, optimizing the distribution and utilization of water resources, and also ensuring the accuracy of water flow switching and discharge during the water path switching process.

[0066] In an optional embodiment, the switching assembly 6 includes a switching body 20 and a sealing disc 21.

[0067] The sealing disc 21 is located in the first cavity 15 and is fixed on the top of the switching body 20, and the sealing disc 21 is used to cover the first water passage 17 or the second water passage 18, the switching body 20 is located in the second cavity 16, and the reset member is arranged between the sealing disc 21 and the switching body 20.

[0068] In the embodiment, a specific implementation of the switching assembly 6 is provided, and in the implementation, the switching assembly 6 includes the switching body 20 and the sealing disc 21. When the water inlet channel 3 stops water feeding for the first time, the water in the second cavity 16 is discharged through the second water outlet channel 5, at this time, the switching body 20 located in the second cavity 16 is subjected to the pressure caused by the water storage in the second cavity 16, and the pressure disappears. Since the water storage space arranged in the switching body 20 is in a water storage state when the water inlet channel 3 stops water feeding for the first time, and the upward force of the reset member on the switching body 20 is less than the sum of the gravity of the switching body 20 and the gravity of the water in the water storage space, the switching body 20 moves downward to the second position. Since the sealing disc 21 is located on the top of the switching body 20, when the switching body 20 moves downward to the second position, the sealing disc 21 covers the second water passage 18. When the water inlet channel 3 stops water feeding for the second time, since the water in the water storage space has been discharged when the water inlet channel 3 feeds water for the second time, and the upward force of the reset member on the switching assembly 6 is greater than the sum of the gravity of the switching body 20 and the sealing disc 21, the switching body 20 moves upward to the first position under the action of the reset member. Since the sealing disc 21 is arranged on the top of the switching body 20, the sealing disc 21 covers the first water passage 17.

[0069] In actual application, through the cooperation of the switching body 20, the sealing disc 21 and the reset member, the function of moving the switching assembly 6 to different positions is realized, so that the sealing disc 21 can cover the corresponding water passage, the leakage and confusion that may occur during water channel switching are prevented, the stable operation of water channel switching is ensured, and a powerful guarantee is provided for the normal operation of the equipment.

[0070] In an optional embodiment, the switching body 20 includes a moving rod 22 and a counterweight water tank 23.

[0071] The reset member is sleeved on the moving rod 22, the top of the moving rod 22 fixes the sealing disc 21 through a clamping groove, and the bottom of the moving rod 22 is integrally formed with the counterweight water tank 23.

[0072] In this embodiment, a specific implementation of the switching body 20 is provided, in which the switching body 20 is provided with a moving rod 22 and a counterweight tank 23. When the water inlet channel 3 stops water for the first time, since the counterweight tank 23 has been filled with water at the first time of water inlet, the counterweight tank 23 will move downward to the second position by the water gravity of itself to overcome the upward force of the reset member. Since the top of the moving rod 22 fixes the sealing disc 21 through the clamping groove, when moving to the second position, the sealing disc 21 will seal the second water passage 18. When the water inlet channel 3 stops water for the second time, since the counterweight tank 23 has been emptied of the internal water resource at the second time of water inlet of the water inlet channel 3, the moving rod 22 and the counterweight tank 23 move upward to the first position under the upward force of the reset member. Since the top of the moving rod 22 fixes the sealing disc 21 through the clamping groove, when moving to the first position, the sealing disc 21 will cover the first water passage 17, preparing for the next water path switching.

[0073] In actual application, the moving rod 22 serves as a bridge connecting the sealing disc 21 and the counterweight tank 23, realizing precise control of water path switching. The clamping groove design at the top ensures stable fixation of the sealing disc 21, preventing the sealing disc 21 from falling off during the switching process. The design of the counterweight tank 23 utilizes the water gravity as driving force to overcome the upward force of the reset member, realizing automatic movement of the switching body 20. In different water inlet stages of the water inlet channel 3, the counterweight tank 23 changes in displacement according to the presence or absence of internal water, and the force of the reset member, which simplifies the operation process of water path switching and improves the automation degree of the water path switching device, making the whole water path switching process more efficient and stable. The integrated setting of the moving rod 22 and the counterweight tank 23 means that the connection is non-detachable, for example, integrally cast, which is not limited here. The connection between the bottom of the moving rod 22 and the counterweight tank 23 avoids problems such as looseness, falling off or poor sealing that may be caused by separation of components, and simplifies the manufacturing process and reduces the assembly steps.

[0074] In an optional embodiment, the top of the second cavity 16 is provided with a water guide slope 25, which is used to guide the liquid in the first cavity 15 into the space outside the counterweight tank 23 in the second cavity 16.

[0075] In this embodiment, a specific implementation of the water guide slope 25 is provided, in which the water guide slope 25 is arranged at the top of the second cavity 16. The water guide slope 25 is used to guide the water flow from the first cavity 15 into the space outside the counterweight tank 23 in the second cavity 16, thereby avoiding the water flow from the first cavity 15 directly falling into the counterweight tank 23 to affect the water outlet timing and effect of the second water outlet channel 5, improving the accuracy and reliability of water path switching.

[0076] In an alternative embodiment, the counterweight tank 23 is provided with a delayed water outlet hole 24 for controlling the liquid discharge speed in the counterweight tank 23.

[0077] In this embodiment, a specific implementation of the counterweight tank 23 is provided, in which the counterweight tank 23 is provided with a delayed water outlet hole 24, and the delayed water outlet hole 24 is in communication with the second cavity 16. When the counterweight tank 23 moves to the second position and the second water inlet of the water inlet channel 3 has not started, the water flow in the counterweight tank 23 will flow slowly to the second cavity 16 through the delayed water outlet hole 24 because the delayed water outlet hole 24 on the counterweight tank 23 is in communication with the second cavity 16, and then the water flow in the second cavity 16 is discharged to the second water outlet channel 5. In actual application, the design of the delayed water outlet hole 24 realizes the smooth transition of the water flow, effectively controls the discharge speed of the water flow, provides sufficient reaction time for the water inlet channel 3 at the waterway switching position, and ensures the stable operation of the entire waterway switching device.

[0078] In an alternative embodiment, the reset member includes an elastic member 19, which is sleeved at the connection between the sealing disc 21 and the moving rod 22, and is used to drive the upward movement of the sealing disc 21.

[0079] In this embodiment, a specific implementation of the reset member is provided, in which the reset member is in the form of an elastic member 19, which is sleeved at the connection between the sealing disc 21 and the moving rod 22. When the counterweight tank 23 contains water and the water gravity thereof is greater than the upward force of the elastic member 19, the sealing disc 21 connected to the top of the moving rod 22 will compress the elastic member 19, so that the elastic member 19 stores upward elastic potential energy. When the liquid in the counterweight tank 23 flows out, because the upward force of the elastic member 19 is greater than the gravity of the switching assembly 6 itself, the elastic member 19 will use the stored upward elastic potential energy to drive the upward movement of the sealing disc 21. In actual application, the design of the elastic member 19 not only improves the response speed and stability of the waterway switching, but also effectively utilizes the elastic properties of the elastic member 19, avoids the energy consumption of the waterway switching, and makes the entire waterway switching device more energy-saving and efficient.
