[0029] As living standards continue to improve, people's requirements for drinking water are also constantly increasing. Household water purifiers have become commonly used small appliances. These purifiers typically include a water circuit board. This board is a component used to guide water flow; water entering the purifier passes through the water circuit board to the filter cartridges, and the water treated by the filter cartridges is then discharged to the outside of the purifier through the water circuit board. However, current water circuit boards used for water purification have complex piping layouts, loose interfaces, and low space utilization.

[0030] To address the aforementioned problems, this application proposes a waterway connection structure.

[0031] Please see Figures 1 to 4 In one embodiment of this application, the water connection structure includes a water conversion component 1. One end of the water conversion component 1 is provided with an inlet 11, an outlet 12, and a wastewater inlet 13. The other side surface of the water conversion component 1 is provided with an inlet connector 14, an outlet connector 15, and a wastewater connector 16. The interior of the water conversion component 1 is provided with an inlet channel 17, an outlet channel 18, and a wastewater channel 19. One end of the inlet channel 17 is connected to the inlet 11, and the other end of the inlet channel 17... One end is connected to the water inlet connector 14; one end of the water outlet channel 18 is connected to the water outlet inlet 12, and the other end of the water outlet channel 18 is connected to the water outlet connector 15; one end of the wastewater channel 19 is connected to the wastewater inlet 13, and the other end of the wastewater channel 19 is connected to the wastewater connector 16; the water inlet 11 is used to connect to the water inlet hole 21 of the filter element 2, the water outlet 12 is used to connect to the water outlet hole 22 of the filter element 2, and the wastewater inlet 13 is used to connect to the wastewater hole 23 of the filter element 2.

[0032] In the above structure, by integrating the inlet 11, outlet 12, wastewater 13, inlet connector 14, outlet connector 15, and wastewater connector 16 into a single water circuit conversion component 1, the use of separate pipes and connectors is reduced, thus simplifying the pipeline layout. Furthermore, the inlet channel 17, outlet channel 18, and wastewater channel 19 are all integrated inside the water circuit conversion component 1, reducing the number of external pipes and making the entire structure more compact and space-saving. The inlet channel 17, outlet channel 18, and wastewater channel 19 of the water circuit conversion component 1 are directly connected at both ends to their corresponding inlets and connectors, and the corresponding inlets directly connect to the corresponding water holes of the filter element 2, reducing intermediate steps, lowering connection complexity, and also reducing potential leakage points. This allows the water circuit connection structure to be arranged in a smaller space, improving space utilization.

[0033] In one embodiment, the water connection structure further includes a filter element 2. The water conversion component 1 is provided with a groove 110. The opening of the groove 110 is provided with a first slot 1101. The water inlet 11, the water outlet 12 and the wastewater inlet 13 are provided on the bottom wall of the groove 110. One end of the filter element 2, which is provided with a water inlet 21, a water outlet 22 and a wastewater hole 23, is located in the groove 110. The side of the filter element 2 facing the first slot 1101 is provided with a snap-fit ​​part 24, which cooperates with the first slot 1101.

[0034] By providing a groove 110 on the water channel conversion component 1 and a first slot 1101 at the opening of the groove 110, a stable installation position can be provided for the filter element 2. Specifically, one end of the filter element 2 is located in the groove 110, and the side of the filter element 2 facing the first slot 1101 is provided with a snap-fit ​​part 24. The snap-fit ​​part 24 is used to cooperate with the first slot 1101, so that the filter element 2 and the water channel conversion component 1 can be quickly snapped on and disassembled, while ensuring the connection stability of the filter element 2 and the water channel conversion component 1.

[0035] In one embodiment, a limiting post 1103 is also provided on the bottom wall of the groove 110, and a limiting hole is provided at one end of the filter element 2. The limiting hole is located at one end of the water inlet hole 21, water outlet hole 22, and wastewater hole 23 of the filter element 2, and the limiting post 1103 is inserted into the limiting hole.

[0036] In the above structure, when the filter element 2 is connected to the water circuit conversion component 1, the cooperation between the limiting post 1103 and the limiting hole provides positioning and guidance for the installation of the filter element 2 and the water circuit conversion component 1, which helps to ensure the correct docking between the filter element 2 and the water circuit conversion component 1, and at the same time enhances the connection stability between the filter element 2 and the water circuit conversion component 1.

[0037] In one embodiment, the opening of the groove 110 is provided with a boss 1102 protruding from the side wall of the groove 110, and the first slot 1101 extends through both sides of the boss 1102 along the extension direction of the side wall; the filter element 2 is provided with an extension section 25 at one end of the water inlet hole 21, water outlet hole 22, and wastewater hole 23, and an abutment part 230 is provided at the connection between the extension section 25 and the filter element 2, and the abutment part 24 includes a protrusion 241 and a second slot 242. The protrusion 241 is provided on the outside of the extension section 25, and the second slot 242 is formed between the protrusion 241 and the abutment part 230; the boss 1102 is located in the second slot 242, and the protrusion 241 and the abutment part 230 abut against both sides of the boss 1102 respectively.

[0038] By providing a boss 1102 at the opening of the groove 110, and having the first slot 1101 pass through both sides of the boss 1102, and providing an extension 25 at one end of the filter element 2, with a protrusion 241 on the outer side of the extension 25, a second slot 242 is formed between the protrusion 241 and the abutment 230. When the filter element 2 is connected to the water circuit conversion component 1, the boss 1102 is located in the second slot 242, and the protrusion 241 and the abutment 230 abut against both sides of the boss 1102, ensuring a tight connection between the filter element 2 and the water circuit conversion component 1 and preventing the filter element 2 from separating from the water circuit conversion component 1 due to changes in water pressure. In addition, the first slot 1101 and the second slot 242 provide a double locking mechanism to ensure a stable connection between the filter element 2 and the water circuit conversion component 1; and the boss 1102 and the groove 110 provide support points for the filter element 2, further enhancing the connection stability between the filter element 2 and the water circuit conversion component 1. During installation, the user can easily align the protrusion 241 of the filter element 2 with the first slot 1101 of the boss 1102, so that the protrusion 241 passes through the first slot 1101 until the extension section 25 of the filter element 2 enters the groove 110, and rotate the filter element 2 so that the protrusion 241 is engaged in the second slot 242. At the same time, the protrusion 241 and the abutment part 230 abut against the two sides of the boss 1102 respectively, so as to realize the quick installation of the filter element 2 and the water circuit conversion component 1.

[0039] In one embodiment, the shape of the first slot 1101 is adapted to the shape of the protrusion 241, so that the protrusion 241 can enter the groove 110 through the first slot 1101.

[0040] By adapting the shape of the first slot 1101 to the shape of the protrusion 241, the protrusion 241 can pass through the first slot 1101 and form a stable lock with the second slot 242, enhancing the connection stability between the filter element 2 and the water circuit conversion component 1. Furthermore, the first slot 1101 and the second slot 242 also provide installation guidance, making the installation process of the filter element 2 smoother and more accurate.

[0041] In one embodiment, the side wall of the water channel conversion component 1 is provided with a mounting plate assembly 120, which surrounds to form an installation space 130. An electrical component 3 is provided in the installation space 130 and is connected to the water inlet channel 17 and / or the water outlet channel 18 and / or the wastewater channel 19.

[0042] By providing a mounting plate assembly 120 on the side wall of the water circuit conversion component 1, and using the mounting plate assembly 120 to form a mounting space 130, the electrical component 3 can be integrated within the mounting space 130, thereby reducing the need for external connection lines and components and simplifying the overall layout. By forming the mounting space 130 inside the mounting plate assembly 120, space can be utilized more effectively, improving the structural compactness of the water circuit connection structure. Furthermore, the electrical component 3 is connected to the inlet channel 17, outlet channel 18, and wastewater channel 19, and can be used to control the flow of water in the inlet channel 17, outlet channel 18, and / or wastewater channel 19, for example, by controlling the water flow using a solenoid valve.

[0043] In one embodiment, the mounting plate assembly 120 includes a first mounting plate 1201 and a second mounting plate 1202, which are located on opposite sides of the water channel conversion component 1. The first mounting plate 1201 forms a first mounting cavity 1301, and the second mounting plate 1202 forms a second mounting cavity 1302. The mounting space 130 includes the first mounting cavity 1301 and the second mounting cavity 1302. The electrical component 3 includes a first valve body 31, a second valve body 32, and a third valve body 33. The first valve body 31 is disposed on the water inlet channel 17, and the third valve body 33 is disposed on the wastewater channel 19. The second valve body 32 is disposed on the water outlet channel 18. The first valve body 31 is located in the first mounting cavity 1301, and the second valve body 32 and the third valve body 33 are disposed in the second mounting cavity 1302.

[0044] By setting up a first mounting plate 1201 and a second mounting plate 1202, and utilizing the first mounting plate 1201 and the second mounting plate 1202 to form a first mounting cavity 1301 and a second mounting cavity 1302 respectively, the electrical component 3 is installed in a partitioned manner, which helps to organize and manage the electrical component 3 and makes maintenance and upgrades more convenient. The electrical component 3 includes a first valve body 31, a second valve body 32, and a third valve body 33, which are respectively located on the inlet channel 17, the outlet channel 18, and the wastewater channel 19, allowing each valve body to operate independently and improving the flexibility of water flow control. Furthermore, the first valve body 31 is located within the first mounting cavity 1301, and the second valve body 32 and the third valve body 33 are located within the second mounting cavity 1302. This layout optimizes space utilization, making the installation of the electrical component 3 more compact and reducing the overall size.

[0045] In one embodiment, the inlet connector 14, the outlet connector 15, and the wastewater connector 16 are fixed at the connection between the water circuit conversion component 1 and the second mounting plate 1202; the inlet channel 17 includes a first water guide channel 171 and a second water guide channel 172, one end of the first water guide channel 171 extends to the connection between the water circuit conversion component 1 and the second mounting plate 1202, and the other end of the first water guide channel 171 extends to the connection between the water circuit conversion component 1 and the first mounting plate 1201, and the end of the first water guide channel 171 away from the inlet connector 14 is connected to the inlet port of the first valve body 31; one end of the second water guide channel 172 extends to the inlet socket 11, and the other end of the second water guide channel 172 extends to the connection between the water circuit conversion component 1 and the first mounting plate 1201; the end of the second water guide channel 172 away from the inlet socket 11 is connected to the outlet port of the first valve body 31.

[0046] The water inlet channel 17 includes a first water guide channel 171 and a second water guide channel 172, allowing for more efficient water distribution within the water circuit conversion component 1, thus improving water flow management efficiency. The first water guide channel 171 and the second water guide channel 172 are respectively connected to the water inlet and outlet ports of the first valve body 31, and the water inlet and outlet ports of the first valve body 31 are also connected to the first water guide channel 171 and the second water guide channel 172, resulting in a compact integration of channels within the water circuit conversion component 1. Furthermore, the water inlet connector 14, the water outlet connector 15, and the wastewater connector 16 are fixed at the connection between the water circuit conversion component 1 and the second mounting plate 1202, making the overall layout more compact and saving space.

[0047] In one embodiment, the filter element 2 includes a filter bottle 26, a first filter element 272, and a second filter element 282. The first filter element 272 and the second filter element 282 are disposed inside the filter bottle 26. The second filter element 282 is disposed inside the first filter element 272. A first fluid flow channel 29 is formed between the first filter element 272 and the inner wall of the filter element 2, and the first fluid flow channel 29 is connected to the water inlet 21. A second fluid flow channel 210 is formed in the middle of the second filter element 282, and the second fluid flow channel 210 is connected to the water outlet 22. A third fluid flow channel 220 is formed inside the first filter element 272, and the third fluid flow channel 220 is connected to the wastewater outlet 23.

[0048] By setting up a first filter element 272 and a second filter element 282, a dual-layer filtration effect can be achieved. The first filter element 272 can intercept larger particles and impurities, while the second filter element 282 can further filter smaller particles, improving water quality. In addition, a first fluid flow channel 29, a second fluid flow channel 210, and a third fluid flow channel 220 are formed inside the filter element 2, allowing water to flow through the filter element 2 in an orderly manner. Each flow channel (first fluid flow channel 29, second fluid flow channel 210, and third fluid flow channel 220) is connected to a corresponding hole (inlet hole 21, outlet hole 22, and wastewater hole 23), ensuring effective water distribution and filtration efficiency. Specifically, the fluid to be filtered enters the inlet channel 17 through the inlet connector 14, passes through the inlet socket, and then enters the filter element 2 through the inlet hole 21. After flowing through the first fluid channel 29, the fluid is filtered by the first filter element 272 to form the first filtered fluid and wastewater (also known as concentrated water). The wastewater passes through the third fluid channel, from which the first filtered fluid enters the second filter element 282 for secondary filtration to form the second filtered fluid. The second filtered fluid converges in the second fluid channel and flows out of the filter element 2 through the outlet hole 22. The second filtered fluid enters the water circuit adapter from the outlet socket 12 and, after flowing through the outlet channel 18, is finally output through the outlet connector 15.

[0049] In one embodiment, the water inlet 11 is sealed to the water inlet hole 21; the water outlet 12 is sealed to the water outlet hole 22; and the wastewater inlet 13 is sealed to the wastewater hole 23.

[0050] In the above structure, the water inlet 11 is sealed to the water inlet 21; the water outlet 12 is sealed to the water outlet 22; and the wastewater inlet 13 is sealed to the wastewater outlet 23. This can prevent water leakage in the filter element 2 and the water circuit conversion component 1, and maintain water pressure and ensure stable transmission within the water circuit connection structure. The sealing connection can be achieved using a sealing ring.

[0051] In one embodiment, a first stop valve 4 is provided in the inlet hole 21, a second stop valve 5 is provided in the outlet hole 22, and a third stop valve 6 is provided in the wastewater hole 23. The stop valves prevent backflow of the water to be filtered, the first filtered fluid, or the second filtered fluid, thus avoiding contamination of the first or second filtered fluid, which is crucial for maintaining water quality. By adding the first stop valve 4, the second stop valve 5, and the third stop valve 6, the filter element 2 can achieve a water-stopping function. The water path conversion component 1 achieves a water-stopping function by the bend of the water along the inlet channel, outlet channel, and wastewater channel, and by cooperating with the first valve body 31, the second valve body 32, and the third valve body 33.

[0052] The technical solution of this application integrates the inlet spigot 11, outlet spigot 12, wastewater spigot 13, inlet connector 14, outlet connector 15, and wastewater connector 16 into a single water circuit conversion component 1, reducing the use of separate pipes and connectors and thus simplifying the pipeline layout. Furthermore, the inlet channel 17, outlet channel 18, and wastewater channel 19 are all integrated inside the water circuit conversion component 1, reducing the number of external pipes and making the entire structure more compact and space-saving. The two ends of the inlet channel 17, outlet channel 18, and wastewater channel 19 of the water circuit conversion component 1 are directly connected to the corresponding spigots and connectors, and the corresponding spigots directly connect to the corresponding water holes of the filter element 2, reducing intermediate links, lowering connection complexity, and also reducing potential leakage points. This allows the water circuit connection structure to be arranged in a smaller space, improving space utilization.

The specific structure of the water circuit connection structure is as described in the above embodiments. Since this water purification device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0054] The inlet connector 14, outlet connector 15, and wastewater connector 16 are used for welding with other connecting pipes of the water purification equipment.
