Description

Technical Field

[0001] This application relates to the field of filter cartridge holders, and more particularly to a filter cartridge holder structure that can be combined with multiple water channels. Background Technology

[0002] The multi-channel filter cartridge holder structure is an integrated water channel design. By combining the filter cartridge holder with the water channel plate, it achieves independent conduction and control of multiple water flows. The filter cartridge is generally installed on the filter cartridge holder and connected to the external water channel through the filter cartridge holder, thereby guiding the water flow into the filter cartridge for filtration. The filtered water then flows out from the water outlet channel of the filter cartridge holder.

[0003] The existing Chinese utility model patent with publication number CN205340311U discloses a filter element base and its application; however, it still has the following shortcomings in practical use:

[0004] The filter base of this patent has a fixed inlet and outlet position (e.g., left inlet and right outlet). The physical position limitation forces the series / parallel connection to rely on special connectors (e.g., single-pass deflector, double straight pipe) to achieve different combinations. Series connection requires a single-pass connector (with internal deflector pipe, requiring high manufacturing precision), while parallel connection requires double straight pipe (increasing the variety of accessories and inventory costs). Utility Model Content

[0005] To address the issue of filter cartridge bases relying on dedicated connectors, this application provides a filter cartridge base structure that allows for multi-channel combination.

[0006] The multi-channel combined filter cartridge holder structure provided in this application adopts the following technical solution:

[0007] A multi-channel combined filter cartridge holder structure includes two or more filter cartridge assemblies for changing the inlet and outlet positions as needed. Each filter cartridge assembly includes a filter cartridge holder body and a filter cartridge housing that are installed together. The filter cartridge housing has an inlet chamber and a filtered outlet chamber inside. Two independent and parallel inlet pipes and an outlet pipe are fixedly connected to both sides of the filter cartridge holder body. The inlet pipes and the outlet pipes have inlet holes communicating with the inside of the inlet chamber and outlet holes communicating with the inside of the filtered outlet chamber, respectively. Two or more straight pipes are provided on the outside of the inlet pipes and the outlet pipes to realize the series and parallel connection of the filter cartridge assemblies.

[0008] By adopting the above technical solution, the interface function can be switched through physical rotation, which is more flexible than the traditional fixed interface. The straight pipe universal design supports any number of filter cartridge combinations.

[0009] Preferably, the water inlet pipe has a first inlet and a first outlet at both ends, which are connected to the two ends of the straight pipe, and the water outlet pipe has a second inlet and a second outlet at both ends, which are connected to the two ends of the straight pipe.

[0010] By adopting the above technical solution, after the filter element holder is rotated 180 degrees, the original water inlet becomes the water outlet, and the series to parallel connection can be converted without replacing the hardware.

[0011] Preferably, the two ends of the straight pipe are respectively provided with an inlet and an outlet. The second outlet of the filter element holder body and the first inlet of another filter element holder body are respectively fixedly connected to the inlet and outlet of a straight pipe to realize the series connection of the water circuit. The first outlet of the filter element holder body and the first inlet of another filter element holder body are respectively fixedly connected to the inlet and outlet of a straight pipe. The second outlet of the filter element holder body and the second inlet of another filter element holder body are respectively fixedly connected to the inlet and outlet of another straight pipe to realize the parallel connection of the water circuit.

[0012] By adopting the above technical solution, water flows through multiple filter elements in sequence to achieve multi-stage filtration. The multiple filter elements work in parallel to increase the flow rate.

[0013] Preferably, the filter cartridge body has a wastewater hole inside that communicates with the inside of the filtered water outlet chamber.

[0014] By adopting the above technical solution, wastewater generated by RO reverse osmosis is discharged through a dedicated channel, avoiding pollution of the water purification system.

[0015] Preferably, the first water inlet is internally fixedly connected with a connector for connecting to an external waterway.

[0016] By adopting the above technical solution, the connector has a built-in sealing ring to prevent raw water leakage.

[0017] Preferably, both the first outlet and the second inlet are fixedly connected with sealing components to assist in achieving series and parallel combinations.

[0018] By adopting the above technical solution, unused water outlets or inlets can be sealed to avoid the risk of leakage.

[0019] Preferably, the top of the wastewater hole, the water inlet hole, and the water outlet hole are all fixedly connected with mounting parts for connecting to the outside.

[0020] By adopting the above technical solution, pressure sensors such as inlet and outlet water pressure monitoring can be installed.

[0021] Preferably, a connecting shell for surrounding and protecting the straight pipe is fixedly connected between the two filter element seats.

[0022] By adopting the above technical solutions, the straight pipe is prevented from being squeezed or collided by external forces, thus improving its durability.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] The filter cartridge holder body and the filter cartridge housing are connected by a cylindrical connection. During installation, the filter cartridge holder body is rotated 180 degrees to interchange the physical positions of the external inlet and outlet holes, with the original left-side outlet moving to the right side. However, the internal water channel connection remains completely unchanged. The inlet hole is still connected to the inlet chamber, and the filtered outlet chamber is connected to the outlet hole. Because the inlet and outlet positions can be interchanged, only a single type of straight pipe is needed for pipe connection. When connected in series, the outlet hole of the filter cartridge holder body is connected to the inlet hole of another filter cartridge holder body through a straight pipe. When connected in parallel, the inlet holes of the two filter cartridge holder bodies are connected to the same water source through a straight pipe, and the outlet holes are connected to the same outlet pipe. The filter cartridge holder body that achieves the above two connection methods is the same filter cartridge holder body. Series and parallel combinations can be achieved by rotation and different connection pipe methods. Attached Figure Description

[0034] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0035] This application discloses a multi-channel combined filter cartridge holder structure.

[0036] Reference Figure 3 , Figure 4 as well as Figure 5 A multi-channel combined filter cartridge holder structure includes two or more filter cartridge assemblies 2. The filter cartridge assembly 2 is used to change the inlet and outlet positions according to needs. The filter cartridge assembly 2 includes a filter cartridge holder body 21 and a filter cartridge housing 211. The filter cartridge holder body 21 can be installed on the top of the filter cartridge housing 211 to guide water flow into the filter cartridge housing 211 for filtration. The filter cartridge housing 211 has an inlet chamber 212 and a filtered water outlet chamber 213 inside. The inlet chamber 212 connects to the external space of the filter cartridge central tube, allowing unfiltered water to enter. The filtered water outlet chamber 213 connects to the filter cartridge central tube, allowing filtered water to enter. The two sides of the filter element assembly 21 are fixedly connected to the inlet pipe 22 and the outlet pipe 23 respectively. The inlet pipe 22 and the outlet pipe 23 are two independent and parallel pipes arranged on both sides of the filter element assembly 21. The inlet pipe 22 has an inlet hole 25 inside, which is connected to the inlet chamber 212. The outlet pipe 23 has an outlet hole 26 inside, which is connected to the filter outlet chamber 213. The inlet pipe 22 and the outlet pipe 23 can be connected to the straight pipe 4 according to the water circuit combination. There are two or more straight pipes 4. The straight pipes 4 are used to realize the series and parallel connection of the filter element assembly 2.

[0037] The opening of the inlet chamber 212 and the outlet chamber 213 creates two nested cylinders of different heights inside the filter housing 211, with the middle being higher and the surrounding area lower. The middle part extends to the inner wall of the outlet hole 26, and the outer part extends to the inner side of the inlet hole 25. This arrangement allows the filter base body 21 to be installed at any angle on the filter housing 211. The prerequisite for installation is that it must be parallel to the other filter base body 21 connected to it. After the filter base body 21 is rotated, the physical positions of the original inlet hole 25 and outlet hole 26 are interchanged, but the internal water channel connection remains unchanged. When the filter housing 211 filters, the water flows into the inlet chamber 212 from the inlet hole 25. Under pressure, the water penetrates the filter medium and the pollutants are intercepted. The clean water flows into the outlet chamber 213 and is discharged from the outlet pipe 23. Color-coded rings are provided at both ends of the straight pipe 4. For example, the blue ring indicates the inlet end and the green ring indicates the outlet end to prevent misinstallation.

[0038] Reference Figure 2 , Figure 6 as well as Figure 7 The inlet pipe 22 has a first inlet 221 and a first outlet 222 at both ends. The first inlet 221 and the first outlet 222 can be connected to both ends of the straight pipe 4 according to the water circuit combination requirements. The outlet pipe 23 has a second inlet 231 and a second outlet 232 at both ends. The second inlet 231 and the second outlet 232 can be connected to both ends of the straight pipe 4 according to the water circuit combination requirements. The straight pipe 4 has an inlet connection port 41 and an outlet connection port 42 at both ends. The second outlet 232 of the filter element holder body 21 is fixedly connected to the inlet connection port 41 of one straight pipe 4, and the first inlet 221 of the other filter element holder body 21 is fixedly connected to the outlet connection port 42 of the straight pipe 4, so as to realize the water outlet inside the filter element holder body 21. Hole 26 is connected to the inlet hole 25 of another filter element holder body 21 via a straight pipe 4, thus achieving a series connection of the water circuit. The first outlet 222 of the filter element holder body 21 is connected to the inlet connection port 41 of a straight pipe 4, and the first inlet 221 of the other filter element holder body 21 is fixedly connected to the outlet connection port 42 of a straight pipe 4, so that the inlet holes 25 of the two filter element holder bodies 21 are connected to the same water source through the straight pipe 4. The second outlet 232 of the same filter element holder body 21 is connected to the inlet connection port 41 of another straight pipe 4, and the second inlet 231 of another identical filter element holder body 21 is fixedly connected to the outlet connection port 42 of another straight pipe 4, so that the outlet holes 26 of the two filter element holder bodies 21 are connected to the same outlet pipe, thus achieving a parallel connection of the water circuit. Figure 6 As shown.

[0039] When connected in series, water flows through the inlet pipe 22 of one filter cartridge body 21 into the inlet hole 25 for filtration. After filtration, the water flows out from the outlet hole 26 of the filter cartridge body 21 and into the outlet pipe 23. The purified water inside the outlet pipe 23 enters the inlet pipe 22 of the other filter cartridge body 21 through the straight pipe 4 connected to the outlet pipe 23, and then enters the inlet hole 25 of the other filter cartridge body 21 for further purification. After purification, the water flows out through the outlet hole 26 of the other filter cartridge body 21 and into the outlet pipe 23 of the other filter cartridge body 21, thus realizing series connection.

[0040] When connected in parallel, one filter cartridge body 21 is connected to the water inlet pipe 22 of the other filter cartridge body 21 through a straight pipe 4. Water flows into the water inlet hole 25 of the two filter cartridge bodies 21 through the water inlet pipe 22 and the straight pipe 4, and flows out from the water outlet hole 26 of the two filter cartridge bodies 21 respectively. The water outlet pipe 23 of the two filter cartridge bodies 21 is connected through another straight pipe 4. The clean water flowing out from the water outlet hole 26 flows out together through the water outlet pipe 23 and the straight pipe 4.

[0041] Reference Figure 1 , Figure 2 as well as Figure 7 The filter cartridge body 21 has a wastewater hole 24 inside, which is connected to the inside of the filter outlet chamber 213. The inside of the first inlet 221 is fixedly connected to the surface of the connector 27. The end of the connector 27 outside the first inlet 221 is threaded for connection to an external water pipe. The connector 27 is used to connect to the first inlet 221 at the beginning of a series or the second outlet 232 at the end of a series or parallel connection, facilitating connection to an external water supply pipe. The inner walls of the first outlet 222 and the second inlet 231 are fixed to the mounting end of the sealing member 28, which is used to assist in achieving series connection. In the combination of parallel and non-parallel, the sealing component 28 is used to block the end of the water inlet pipe 22 and the water outlet pipe 23 that is not connected to the straight pipe 4 and the connector 27, and to assist in the connection of the water circuit combination. The tops of the wastewater hole 24, the water inlet hole 25 and the water outlet hole 26 are respectively fixed to three mounting components 29. The mounting components 29 are used to connect to the outside. The sides of the two filter element body 21 that are close to each other are respectively fixed to the two ends of the connecting shell 3. The connecting shell 3 is used to surround and protect the straight pipe 4 to reduce external interference. The outer surface of the filter element body 21 is fixedly connected to the mounting plate 1. The mounting plate 1 is used to limit and fix the filter element assembly 2.

[0042] The mounting part 29 connected to the wastewater hole 24 can be sealed by the sealing part 28 when not needed. The mounting part 29 connected to the water inlet hole 25 can be connected to the water inlet pressure transmitter (ELE-801) to monitor the raw water pressure. The mounting part 29 connected to the water outlet hole 26 can be connected to the water outlet pressure sensor (HE26) to monitor the purified water pressure. The connecting shell 3 is made of transparent material and has a built-in slot for positioning the straight pipe 4. The installation error tolerance is ±2mm.

[0043] The implementation principle of a multi-channel combined filter cartridge holder structure in this application embodiment is as follows: the connection between the filter cartridge holder body 21 and the filter cartridge housing 211 is a cylindrical connection. During installation, the filter cartridge holder body 21 is rotated 180 degrees to interchange the physical positions of the external inlet hole 25 and outlet hole 26, moving the original left-side opening to the right-side opening. However, the internal water channel connection remains completely unchanged. The inlet hole 25 is still connected to the inlet cavity 212, and the filtered outlet cavity 213 is connected to the outlet hole 26. After the filter cartridge holder body 21 is rotated, the physical positions of the original inlet hole 25 and outlet hole 26 are interchanged, but the internal water channel connection remains unchanged. During filtration, water flows from the inlet hole 25 into the inlet cavity 211. Inside the filter 12, water flows under pressure and penetrates the filter medium, while pollutants are trapped. The purified water flows into the filter outlet chamber 213 and is discharged from the outlet pipe 23. Since the inlet and outlet positions can be interchanged, only a single type of straight pipe 4 is needed for pipe connection. When connected in series, the outlet hole 26 of the filter cartridge body 21 is connected to the inlet hole 25 of another filter cartridge body 21 through the straight pipe 4. When connected in parallel, the inlet holes 25 of the two filter cartridge bodies 21 are connected to the same water source through the straight pipe 4, and the outlet holes 26 are connected to the same outlet pipe. The filter cartridge body 21 that achieves the above two connection methods is the same filter cartridge body 21. The combination of series and parallel connection can be achieved by rotating 180 degrees and using different connection pipes.

[0044] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
