Description

Technical Field

[0001] This utility model relates to the field of water circuit board technology, and more specifically, to a multifunctional integrated structure for a water circuit board. Background Technology

[0002] Water circuit boards integrate multiple components of traditional pipe connections into a three-dimensional integrated water circuit, reducing the amount of pipes and connectors used in water purifiers. This lowers the risk of leaks caused by improper pipe insertion and removal, as well as space occupation, making water purifiers smaller, more compact, and safer. Therefore, water circuit boards are widely used in water purifiers. Currently, water circuit boards used in RO machines integrate the internal water circuit into the water circuit board assembly. However, the inlet solenoid valve on the water circuit board assembly has a fixed position, and the external water outlet interface function is fixed, resulting in a single function for the entire machine.

[0003] In view of this, the applicant hereby submits this application after studying the existing technology. Utility Model Content

The inlet channel is provided with an inlet port and an outlet port of an inlet solenoid valve at its front end for connecting the inlet solenoid valve. The water circuit board assembly is provided with a notch near the inlet port and outlet port of the inlet solenoid valve.

[0006] An integrated module is adaptable to be installed in the notch. It has several reversing grooves, and two adjacent reversing grooves are respectively provided with a first-stage filter element inlet and a first-stage filter element outlet for connecting the first-stage filter element. The several reversing grooves can be adapted to and connected to the flow channels around the notch, so that the integrated module can reverse the flow of the inlet flow channel and the flow of the outlet flow channel, so that the inlet water flows through the inlet solenoid valve first or flows through the first-stage filter element first.

[0008] As a further optimization, the water inlet channel is provided downstream of the water inlet solenoid valve and the first-stage filter element, and sequentially along the water path direction with a booster pump inlet, a booster pump outlet, and a second-stage filter element inlet. The pure water channel has a pure water outlet at its starting end, and the wastewater channel has a wastewater outlet at its starting end. The second-stage filter element inlet, pure water outlet, and wastewater outlet are used to connect to the second-stage filter element so that the incoming water flow can be filtered through the second-stage filter element to produce pure water and wastewater.

[0016] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0017] This application provides a multifunctional integrated water circuit board structure. By setting a notch on the water circuit board assembly and a reversing groove on the integrated module, the integrated module is installed on the notch.

[0030] Example

[0031] Depend on Figures 1 to 9 As shown, this utility model embodiment provides a multifunctional water circuit board integrated structure including a water circuit board assembly 1 and an integrated module 6. The water circuit board assembly 1 is provided with an inlet channel 2, an outlet channel 3, a pure water channel 4, and a wastewater channel 5. The inlet channel 2 is provided with an inlet 21 and an outlet 22 of an inlet solenoid valve at its front end for connecting the inlet solenoid valve. The water circuit board assembly 1 is provided with a notch 13 near the inlet 21 and outlet 22 of the inlet solenoid valve. The integrated module 6 can be adapted to be installed on the notch 13. It is provided with a plurality of reversing grooves 61, and a first-stage filter element inlet 62 and a first-stage filter element outlet 63 are respectively provided in two adjacent reversing grooves 61 for connecting the first-stage filter element. The plurality of reversing grooves 61 can be adapted to and connected to the flow channels around the notch 13, so that the integrated module can reverse the flow of the inlet flow channel 2 and the outlet flow channel 3, so that the inlet water flows through the inlet solenoid valve first or flows through the first-stage filter element first.

[0032] In this embodiment, the inlet channel 2 and outlet channel 3 are reversed by the reversing groove 61 on the integrated module 6, changing the direction of the inlet water flow. This allows the inlet water to flow first through the inlet solenoid valve or first through the first-stage filter element, thus changing the order of the inlet solenoid valve and the first-stage filter element. When it is necessary to change the order of the inlet solenoid valve and the first-stage filter element, only the integrated module 6 needs to be replaced. The reversing groove 61 with different directions on the integrated module 6 reverses the direction of the inlet channel 2 and outlet channel 3, which is convenient and simple, allowing the water circuit board to be adapted to more models and achieve more water output functions. The integrated module 6 can be assembled into the water circuit board assembly 1 through processes such as welding, gluing, or injection molding.

[0033] Specifically, one end of the water circuit board assembly 1 is provided with an inlet 23, a first outlet 31, a second outlet 41 and a third outlet 51. The inlet 23 is connected to the inlet channel 2 and is used to connect to the tap water pipe. The first outlet 31 is connected to the outlet channel 3. The second outlet 41 is connected to the pure water channel 4. The third outlet 51 is connected to the wastewater channel 5.

[0034] Reference Figure 1 and Figure 2 As shown, downstream of the inlet solenoid valve and the first-stage filter element, the inlet channel 2 is sequentially equipped with a booster pump inlet 24, a booster pump outlet 25, and a second-stage filter element inlet 26 along the water flow direction. The pure water channel 4 has a pure water outlet 42 at its starting end, and the wastewater channel 5 has a wastewater outlet 52 at its starting end. The second-stage filter element inlet 26, pure water outlet 42, and wastewater outlet 52 are used to connect to the second-stage filter element. The second-stage filter element can be an RO filter element, allowing the incoming water flow to be filtered through the RO filter to produce pure water and wastewater. The pure water channel 4 has a third-stage filter element inlet 43 and a third-stage filter element outlet 44 between the pure water outlet 42 and the second outlet 41, used to connect to the third-stage filter element for further filtration of the pure water. The pure water flow channel 4 is provided with a one-way valve inlet 45 and a one-way valve outlet 46 between the third-stage filter inlet 43 and the pure water outlet 42, for connecting the one-way valve to prevent the pure water filtered by the RO filter from flowing back. The wastewater flow channel 5 is provided with a wastewater solenoid valve inlet 53 and a wastewater solenoid valve outlet 54 between the wastewater outlet 52 and the third outlet 51, for connecting the wastewater solenoid valve to control the flow of wastewater. The water circuit board assembly 1 includes an upper water circuit board 11 and a lower water circuit board 12, which are joined together to form a flow channel. To make the structure more compact, the inlet and outlet of the external device can be adapted to be opened on the upper water circuit board 11 or the lower water circuit board 12.

[0035] like Figure 8As shown, when the inlet water flows through the inlet solenoid valve, the outlet channel 3 is connected to the one-way valve outlet 46. At this time, the inlet water enters the inlet channel 2 from the inlet 23, and flows through the inlet solenoid valve, the first-stage filter element, and the booster pump in sequence, before flowing into the second-stage filter element. The second-stage filter element filters out pure water and wastewater. The wastewater enters the wastewater channel 5 from the wastewater outlet 52, and flows through the wastewater solenoid valve before flowing out from the third outlet 51. The pure water enters the pure water channel 4 from the pure water outlet 42, and after passing through the one-way valve, it can be split into one stream to enter the outlet channel 3 and flow out from the first outlet 31. The first outlet 31 can be connected to a water storage tank, which can store pure water when the RO machine is idle and increase the pure water flow rate when the user turns on the tap next time. Another stream of pure water flows to the third-stage filter, where it is further filtered before flowing out from the second outlet 41 to supply water to users.

[0036] Reference Figure 9 As described above, when the incoming water flows through the first-stage filter element, the outlet channel 3 is connected to the outlet 63 of the first-stage filter element. At this time, the incoming water enters the inlet channel 2 from the inlet 23, and flows sequentially through the first-stage filter element, the inlet solenoid valve, and the booster pump before flowing into the second-stage filter element. The second-stage filter element filters out pure water and wastewater. The wastewater enters the wastewater channel 5 from the wastewater outlet 52, flows through the wastewater solenoid valve, and exits from the third outlet 51. The pure water enters the pure water channel 4 from the pure water outlet 42, and flows sequentially through the check valve and the third-stage filter element before exiting from the second outlet 41, supplying water to the user. Additionally, after the incoming water passes through the first-stage filter element, a branch can be diverted into the outlet channel 3 and exit from the first outlet 31 for the user's daily water needs.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
