Description

Technical Field

[0001] This application relates to the field of water purification equipment, and in particular to a water circuit device and a water purifier. Background Technology

[0002] Existing water purifiers integrate core components such as filter cartridges, pumps, and control boards. However, due to the limited internal space, the water circuit board must integrate complex flow channels within a limited volume. This not only results in tight axial spacing between the flow channels but also directly leads to insufficient space for functional expansion and a limited number of reserved pipe openings. If pipe openings are added directly inside the water purifier, the installation positions of the new pipe openings and supporting components are prone to spatial interference with existing components, resulting in poor compatibility of the water circuit board installation. This not only increases the complexity of the piping layout but also further reduces the internal space of the equipment, hindering the miniaturization of water purifiers. Utility Model Content

[0020] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0021] The following is combined Figures 1 to 6 The embodiments of this utility model are described below.

[0022] This application provides a water circuit device, which includes a water circuit board 100, a water supply component 200, and a pipeline machine component 300.

[0023] Specifically, the water circuit board 100 has multiple pipe interfaces, which are centrally located on the water circuit board 100, facilitating the connection of other expansion components, improving the adaptability of the water circuit board 100, and also improving installation efficiency. A water supply component 200 is located on one side of the water circuit board 100 and is used to supply water to other expansion components; the pipeline machine component 300 is arranged opposite to the water supply component 200, and the multiple pipe interfaces are respectively connected to and communicate with the water supply component 200 and the pipeline machine component 300, thereby setting up a water flow channel between the water supply component 200 and the pipeline machine component 300 on the water flow device, thus providing an expansion interface for the pipeline machine and expanding the function of the water circuit device.

[0024] During installation, the water supply assembly 200 and the water dispenser assembly 300 can be pre-assembled with the water circuit board 100 before being installed as a whole, improving installation efficiency. In use, filtered water enters the water supply assembly 200 through one of the pipe interfaces on the water circuit board 100, and the water supply assembly 200 then delivers the water to the water dispenser assembly 300 or other components requiring water supply. The water dispenser assembly 300 can be connected to an external water dispenser at its outlet for user use, as needed. Simultaneously, other pipe interfaces on the water circuit board 100 can be connected to expansion components; that is, multiple other pipe interfaces on the water circuit board 100 can serve as expansion ports to connect additional filter cartridges, components, etc., with water flowing through these interfaces in the pre-designed flow channels inside the water circuit board 100. Furthermore, the relative arrangement of the water supply assembly 200 and the water dispenser assembly 300 on both sides of the water circuit board 100 reduces pipe crossings and direct spatial stacking between the two components.

[0025] Therefore, by arranging pipe interfaces on the water circuit board 100, the water supply component 200 and the pipeline machine component 300 are connected to the pipe interfaces, which facilitates the provision of expansion interfaces on the water circuit device. At the same time, by placing the water supply component 200 and the pipeline machine component 300 on both sides of the water circuit board 100, the length of the connecting pipes and the number of bends are reduced, the structural layout of the entire water circuit device is optimized, and conditions are provided for the miniaturization of the water purifier.

[0026] In some embodiments, the water circuit board 100 includes a board body 110 and a pure water inlet pipe 111, a first water outlet pipe 112, and a second water outlet pipe 113 disposed on the board body 110 and extending laterally along the board body 110. The multiple inlet pipes and outlet pipes form multiple pipeline interfaces. The pure water inlet pipe 111 and the first water outlet pipe 112 are disposed on the side of the board body 110 near the water supply assembly 200 for connection to the water supply assembly 200. The second water outlet pipe 113 is disposed on the side of the board body 110 near the pipeline machine assembly 300 for connection to the pipeline machine assembly 300.

[0027] In actual use, the purified water filtered by the filter element enters through the pure water inlet pipe 111 on the side of the water circuit board 100 closest to the water supply component 200 via the board body 110. The water flows along the pure water inlet pipe 111 into the water supply component 200, and then along the water supply component 200 into the water dispenser component 300. After receiving the water from the water supply component 200, the water dispenser component 300 flows out through the second outlet pipe 113 on the other side of the board body 110. In this way, the connection distance between each component and the pipeline can be shortened, which not only reduces the length of the internal pipeline, but also reduces the cross-stacking of pipelines between the water supply component 200 and the water dispenser component 300 due to spatial overlap, thereby optimizing the internal layout and facilitating later maintenance.

[0028] In some embodiments, the water supply assembly 200 includes a three-way valve 210, a self-priming pump 220, and a negative pressure valve 230. The three-way valve 210 and the negative pressure valve 230 are arranged sequentially in the horizontal direction, and the self-priming pump 220 is located below the negative pressure valve 230. The water supply-related components are compactly arranged on one side of the water circuit board 100, thereby making full use of the vertical space and avoiding the components in the water supply assembly 200 from being connected to or intersecting with other components and occupying too much horizontal space.

[0029] Specifically, the inlet of the three-way valve 210 is connected to and communicates with the pure water inlet pipe 111, the first outlet of the three-way valve 210 is connected to and communicates with the inlet of the negative pressure valve 230, the outlet of the negative pressure valve 230 is connected to and communicates with the inlet of the self-priming pump 220, and the outlet of the self-priming pump 220 is connected to the first outlet pipe 112. The three-way valve 210 achieves flow diversion, dividing the pure water into two paths. One part flows out through the water supply assembly 200 and sequentially flows to the negative pressure valve 230 and the self-priming pump 220 for processing before flowing out or connecting to other modules. The negative pressure valve 230 reduces the water pressure at the front end of the water supply pipe, creating stable water suction conditions for the self-priming pump 220, enabling the self-priming pump 220 to pump water stably and improving the stability of the water supply. The other part supplies the pipeline machine assembly 300.

[0030] To control the flow of this portion of the pipeline in the water dispenser assembly 300, in some embodiments, the water dispenser assembly 300 includes a solenoid valve 310 and a bracket 320. The solenoid valve 310 is positioned opposite the three-way valve 210 to utilize longitudinal space and reduce the length of the connecting pipeline between the two components. The inlet end of the solenoid valve 310 is connected to and communicates with the second outlet end of the three-way valve 210, and the outlet end of the solenoid valve 310 is connected to the second outlet pipe 113. The solenoid valve 310 controls the flow of this portion of the pipeline, allowing for opening or closing of the passage to switch modes when the external water dispenser is used. The solenoid valve 310 is fixed to the bracket 320, which is used for securing with other accessories. During actual assembly, the bracket 320, through its cooperation with the water purifier housing 430, fixes the position of the solenoid valve 310, preventing the solenoid valve 310 from shifting or shaking due to vibration during operation.

[0031] Detection elements often need to be connected to the water system via additional pipes. Multiple pipes not only easily occupy internal space but also pose risks such as leaks due to excessive pipe connections. Therefore, in some embodiments, the water system board 100 further includes a vertically extending detection pipe 114. The vertical extension of the detection pipe 114 fully utilizes the space of the water system board 100. The detection pipe 114 is mounted on the board body 110, with one end connected to and communicating with the second water outlet pipe 113, and the other end used for connecting to other detection elements.

[0032] For example, the detection element is a high-pressure switch 115, used to detect the pressure generated by the water flow. The high-pressure switch 115 is installed on the detection pipe 114, which guides the water flow to the high-pressure switch 115. The high-pressure switch 115 is connected to the control center of the water purifier. The control center can control the water intake operation based on the water pressure signal detected by the high-pressure switch 115. That is, when filtered water flows in through the horizontal second outlet pipe 113 and along the vertical detection pipe 114, the high-pressure switch 115 detects the corresponding water pressure, allowing the control center of the water purifier to take corresponding actions based on the detected water pressure signal. For example, when the water pressure signal shows that the water pressure detected by the high-pressure switch 115 is higher than a preset pressure value, the control center can control the water purifier to stop the water intake operation; conversely, when the water pressure is lower than the preset pressure value, the control center can control the water purifier to start the water intake operation.

[0033] In some embodiments, the pipeline machine assembly 300 further includes a one-way valve located in the pipeline between the solenoid valve 310 and the second outlet pipe 113. Water flows through the solenoid valve 310 into the one-way valve, which allows water to flow in one direction to prevent backflow. In an optional embodiment, the high-pressure switch 115 can be integrated with the one-way valve in the pipeline to enable unidirectional water flow, preventing backflow and thus reducing leakage or other points of failure.

[0034] Furthermore, the bracket 320 includes abutment portion 321 and folding portion 322, which are fixedly connected. The bottom of the solenoid valve 310 abuts against the abutment portion 321, and the side of the solenoid valve 310 abuts against the folding portion 322. As shown in the figure, the bracket 320 is integrally formed in an "L" shape. During installation, the bottom of the solenoid valve 310 is placed on the abutment portion 321 of the bracket 320, so that the side of the solenoid valve 310 fits against the folding portion 322. This allows the abutment portion 321 and the folding portion 322 to support the solenoid valve 310 from the bottom and side, respectively, preventing the solenoid valve 310 from shifting due to vibration or water flow impact.

[0035] Furthermore, the abutment portion 321 is provided with a connecting hole 323 and a retaining hole 324. One end of the solenoid valve 310 passes through the connecting hole 323 and communicates with the second water outlet pipe 113. The retaining hole 324 is used to cooperate with other accessories to fix the position of the bracket 320. In actual use, fasteners such as bolts pass through the retaining hole 324 on the abutment portion 321 to cooperate and fix the bracket 320 with the housing 430 of a water purifier, thereby fixing the overall position of the solenoid valve 310. To further fix the solenoid valve 310, corresponding fixing holes 325 can also be provided on the folding portion 322, and fasteners can be used to fix the solenoid valve 310 to the folding portion 322.

[0036] This application also provides a water purifier, which includes a filter element assembly and a water circuit device as described in any of the preceding technical solutions. Because it incorporates the water circuit device disclosed in the above embodiments, it possesses all the technical advantages of the aforementioned water circuit devices. In some optional embodiments, the filter element assembly includes a pre-filter 410 and a composite filter 420, the pre-filter 410 and the composite filter 420 being respectively connected to the pipeline interface, and the water circuit device being disposed between the pre-filter 410 and the composite filter 420. This integrated design of the filter element assembly and the water circuit device not only expands the functionality of the water purifier but also allows for a more compact internal layout, reducing the overall space occupied by the filter element and the water circuit device, thereby achieving miniaturization of the water purifier. Furthermore, it reduces the number of interfaces, thereby lowering the probability of malfunctions such as leaks.
