Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and more specifically, to a water circuit board. Background Technology

[0002] Water purifiers are widely used in various water treatment scenarios as important equipment for water purification. For example, in home water purification, the flow rate of the water circuit boards in current water purifiers is relatively small, which cannot meet the water needs of the whole house. Moreover, only one filter element can be installed in each water circuit of the water circuit board, resulting in a very small amount of purified water. If the filter element size is increased to increase the water production, the filter element size will be very large, which will affect the overall cost and ease of installation. Utility Model Content

[0032] The present invention provides a water circuit board, which aims to solve the above-mentioned technical problems of the prior art.

[0033] The technical solution of this utility model and how the technical solution of this utility model solves the above-mentioned technical problems will be described in detail below with specific embodiments.

[0034] This utility model embodiment provides a water channel board product, the structural schematic diagram of which is shown below. Figure 1 - Figure 4 As shown, it includes: a liquid inlet 10, a liquid outlet 20, and at least two filter components 30; the filter components 30 are provided with a liquid inlet 80 and a liquid outlet 90, the liquid inlet 10 is provided with at least two first connection positions, and the liquid outlet 20 is provided with at least two second connection positions; one liquid inlet 80 is connected to one of the first connection positions to communicate with the liquid inlet 10, and one liquid outlet 90 is connected to one of the second connection positions to communicate with the liquid outlet 20.

[0035] For example, the inlet 10 and outlet 20 can be circular tubes, allowing liquid to pass through their interiors. Multiple first connection points are distributed along the axial direction of the inlet tube, and multiple second connection points are distributed along the axial direction of the outlet tube. For clarity, two filter assemblies 30 are used as an example, so the number of first and second connection points is two each.

[0036] In this embodiment, the two filter components 30 between the inlet and outlet pipes are connected in parallel. Therefore, when liquid enters the inlet pipe, it is simultaneously filtered by both filter components 30, resulting in purified liquid entering the outlet pipe. The dual purified liquid channels provide sufficient flow to the outlet pipe.

[0037] Based on the above idea, three or more filter components 30 can be set in parallel, which will not be elaborated here.

[0038] Optionally, the filter assembly 30 includes a housing 31 and a filter element 32; the filter element 32 is disposed in the housing 31 and divides the housing 31 into a raw liquid area and a purified liquid area, the inlet 80 is disposed in the housing 31 and communicates with the raw liquid area, and the outlet 90 is disposed in the housing 31 and communicates with the purified liquid area.

[0039] For example, filter element 32 is a filter screen. The liquid (raw liquid) in the inlet pipe becomes purified liquid after being filtered by filter element 32. The purified liquid flows out from the outlet pipe, thus completing the purification.

[0040] Optionally, the housing 31 is provided with a liquid treatment chamber 310; the filter element 32 is a cylindrical structure, and the cylindrical filter element 32 divides the liquid treatment chamber to form an outer ring cavity 3101 and a central cavity 3102 that are surrounded by the outer ring cavity 3101 and the central cavity 3102, respectively; one of the outer ring cavity 3101 and the central cavity 3102 is the original liquid area and the other is the purified liquid area.

[0041] Specifically, in combination Figure 2 The walls of the liquid treatment chamber 310 seal both ends of the cylindrical filter element 32. Thus, the channel between the outer annular cavity 3101 and the central cavity 3102 passes through the periphery of the filter element 32. Preferably, the outer annular cavity 3101 is the raw liquid zone, and the central cavity 3102 is the purified liquid zone. In this embodiment, both the outer annular cavity 3101 and the central cavity 3102 are cylindrical and concentrically arranged. Thus, the raw liquid in this embodiment undergoes radial filtration, which results in a larger filtration area and faster filtration speed. Simultaneously, the raw liquid zone surrounds the central zone, causing the raw liquid in the raw liquid zone to permeate from the outside in, further improving filtration efficiency. In other embodiments, the filter element 32 has a cylindrical structure with only one open end. This open end connects to the wall of the liquid treatment chamber 310 and communicates with the outlet 90. As can be seen above, the space inside the filter element 32 is the purified liquid zone.

[0042] Similarly, the original solution enters the original solution zone through the inlet 80, becomes purified solution after being filtered by the filter screen, enters the purified solution zone, and finally flows out from the outlet 90.

[0043] More preferably, to improve the filtration efficiency of the filter, the volume of the central cavity 3102 can be set to 1.5-2 times the volume of the outer ring cavity 3101. The inlet pipe and the outlet pipe are arranged in parallel to each other, and the two filter components 30 are located on the same side of the inlet pipe and the outlet pipe.

[0044] Other chambers, such as the outer ring chamber 3101 (clean liquid zone) and the central chamber 3102 (original liquid zone), can also achieve the above filtration results, which will not be elaborated here.

[0045] Alternatively, the filter assembly 30 may include a filter tube and a filter screen. One end of the filter tube is an inlet 80, and the other end is an outlet 90. The filter screen is installed inside the filter tube. According to the aforementioned scheme, the filter screen divides the inside of the filter tube into a raw liquid area and a purified liquid area. Therefore, the filtration principle of the filter tube is as described above, and will not be elaborated here.

[0046] Optionally, it also includes a reinforcing rib 70, which acts on the inner wall of the liquid treatment cavity 310 and is located in the locking outer ring cavity 3101.

[0047] For example, the reinforcing rib 70 can be selected as a polygonal support block, and multiple reinforcing ribs 70 are evenly spaced along the inner wall of the liquid processing cavity 310. The support block is connected to the bottom side wall of the liquid processing cavity 310 to provide support for the side wall.

[0048] Optionally, it also includes a rinsing component 50, which is provided with a rinsing channel that connects to the clean liquid area.

[0049] For example, the rinsing element 50 is a rinsing pipe. Preferably, all the aforementioned clean liquid zones are connected to a single rinsing pipe, thereby reducing the number of rinsing pipes. The key point is that the rinsing pipe is used for directional rinsing. Specifically, in conventional liquid filtration, the raw liquid flows from the raw liquid zone to the clean liquid zone. Therefore, along the direction the raw liquid passes through the filter screen, impurities adhere to it or even become embedded in the filter screen due to the force of the liquid flow from the outside in. Therefore, regardless of the type of impurity, it needs to be cleaned promptly to avoid reducing the filtration efficiency of the filter screen.

[0050] When reverse cleaning is required, cleaning fluid is introduced into the clean liquid area of ​​the cleaning pipeline. The cleaning fluid can be discharged simultaneously through both the inlet and outlet pipes. It should be noted that the rinsing fluid entering the raw liquid area from the clean liquid area, passing through the filter screen, washes away impurities on the filter screen and then exits through the inlet pipe. Alternatively, the rinsing fluid can enter through the inlet pipe following the normal filtration process, pass through the filter screen, and flow out through either the outlet or rinsing pipe; this process is called forward cleaning.

[0051] Furthermore, regardless of whether it's forward or reverse cleaning, this embodiment can connect an external drain pipe to the raw solution area, allowing the cleaning fluid to drain during either process. The purpose of this external drain pipe is twofold: firstly, during reverse cleaning, the cleaning fluid entering the raw solution area can be quickly discharged through the external drain pipe, eliminating the need for the inlet pipe. Secondly, during forward cleaning, impurities on the filter screen cannot pass through, hindering the flow of cleaning fluid. Under the rinsing action of the rinsing fluid, these impurities are dislodged and discharged through the external drain pipe, improving the efficiency of the cleaning fluid passing through the filter screen during forward cleaning. Moreover, the aforementioned forward and reverse cleaning can be performed alternately to achieve a better cleaning effect.

[0052] Preferably, the flushing component 50 is arranged parallel to the inlet pipe or the outlet pipe, and is located between the inlet pipe and the outlet pipe, so that the three are arranged on the same plane, reducing the space occupied.

[0053] Preferably, it also includes a control valve, which is disposed on the flushing channel to control the opening and closing of the flushing channel.

[0054] For example, the control valve (not shown) is a solenoid valve. Additionally, a drain pipe 60 is provided in the middle of the flushing element 50, and the control valve is mounted on the drain pipe 60. Both the inlet and outlet of the flushing element 50 are through the drain pipe 60. It should be noted that the flushing element 50 is simultaneously connected to the drain pipe located in the middle of the flushing element 50.

[0055] Optionally, the housing 31 includes a main body 311 and a cover 312; the main body 311 is hollow in the middle and has an opening at one end, and the cover 312 is closed to the opening to form a liquid processing chamber 310, with an inlet 80 and an outlet 90 respectively disposed on the main body 311.

[0056] In this embodiment, the housing 31 is preferably cylindrical. As mentioned above, there are two filter components 30. Therefore, there are two main bodies 311 and two cover bodies 312. The two main bodies 311 are arranged axially along the inlet pipe and the outlet pipe.

[0057] Specifically, to avoid the problem of parts scattering due to multiple covers 312, multiple covers 312 can be installed as a single unit.

[0058] In addition, in order to facilitate observation of the internal condition of the liquid treatment chamber 310, a viewing window can be provided on the cover 312. However, a transparent plate can be provided to seal the window, so that the filtration condition inside the liquid treatment chamber 310 can be observed through the window.

[0059] Optionally, the liquid outlet 20 is provided with a first liquid outlet port 201 and a second liquid outlet port 202; the liquid outlet volume of the first liquid outlet port 201 is less than the liquid outlet volume of the second liquid outlet port 202.

[0060] This embodiment demonstrates that the flow rate of the purified liquid can be allocated according to different design requirements. Preferably, taking a circular outlet as an example, the area of ​​the second outlet port 202 is 2-3 times that of the first outlet port 201.

[0061] In addition, in this embodiment, the second liquid outlet port 202 can be a port of the liquid outlet pipe, and the first liquid outlet port 201 is disposed on the side wall of the liquid outlet pipe. The first liquid outlet port 201 guides the liquid outward through the external pipe.

[0062] Optionally, it also includes a fixing plate 40, an inlet 10, an outlet 20, and at least two filter assemblies 30 disposed on the fixing plate 40.

[0063] To enhance the overall integrity of the water circuit board and facilitate its installation or disassembly, preferably, the fixing plate 40 is a square plate, with the aforementioned inlet component 10 and outlet component 20 located on one side of the fixing plate 40, and the filter assembly 30 disposed on the opposite side of the fixing plate 40.

[0064] In addition, the entire water circuit board can be made as an injection molded part, wherein the fixing plate 40, the liquid inlet 10, the liquid outlet 20 and the main body 311 can be integrally molded. The aforementioned control valve 60 can be fixed on the fixing plate 40.

[0065] Based on the foregoing, it is known that both ends of the flushing pipe, inlet pipe, and outlet pipe can serve as either inlets or outlets. In this embodiment, to reduce the number of pipe connections, one end of each of the three pipes is sealed with a plug; specifically, the flushing pipe is sealed at both ends. Furthermore, the sealed ends of the flushing pipe and inlet pipe can preferably be provided with external threads for screw connection to external pipes.

[0066] A filter includes the aforementioned water circuit board. The inlet 10 of the water circuit board is connected to the filter's inlet. A first outlet port 201 and a second outlet port 202 of the outlet 20 are respectively connected to the filter's outlet corresponding to the flow rate. For example, the first outlet port 201 is used to connect to a reverse osmosis water purifier; the second outlet port 202 can be used to connect to a whole-house water system. In other embodiments, the water circuit board can be used for various types of filters, which will not be listed here.
