[0040] To enable those skilled in the art to better understand the technical solution of this utility model, the modular filtration system of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] This utility model provides a modular filtration system, including a filter element frame 10 and a water circuit assembly 20. Two or more filter element frames 10 are provided, each filter element frame 10 is independently configured, and each filter element frame 10 corresponds to one filter element module 30. The water circuit assembly 20 has internal channels for water flow.

[0042] Combination Figure 4A , Figure 5A As shown, the filter element frame 10 can adopt different structural designs. The filter element frames 10 have the same shape and match each other in size. When two filter element frames 10 are close to each other, the side walls of the two filter element frames 10 match and connect with each other.

[0043] The filter element frame 10 is provided with a cavity for accommodating the filter element module 30, and each filter element module 30 is placed in a cavity of one filter element frame 10. Each filter element frame 10 is provided with a fixing component 110, and one filter element module 30 is fixedly installed in each filter element frame 10 by the fixing component 110.

[0044] The two adjacent filter frames 10 can be detachably fixed together. The corresponding number of filter frames 10 can be spliced ​​and fixed according to the number of filter modules 30 required by the entire modular filtration system. The number of filter frames 10 included in the entire modular filtration system can be increased or decreased arbitrarily.

[0045] Combination Figure 1A , Figure 1B As shown, the structural design of setting two filter element frames 10 is illustrated. In this embodiment, two filter element modules 30 are installed. This embodiment is only one specific case. More filter element frames 10 and more filter element modules 30 can be set.

[0046] Each filter element frame 10 is equipped with a water channel assembly 20, and the filter element module 30 is connected to the water channel assembly 20. The water channel assembly 20 has a water flow channel inside, and the water in the filter element module 30 flows according to a preset path by installing the water channel assembly 20. Different water channel assemblies 20 are connected by pipes, so that different filter element modules 30 form a water treatment system, and each filter element performs filtration in a different sequence.

[0047] The water circuit assembly 20 connects the different filter modules 30 to each other, and the water circuit assembly 20 connects the filter modules 30 in series or in parallel. The filter modules 30 play different filtration roles in different positions, and the different filter modules are combined to realize the water treatment process.

[0048] A filter element frame 10 houses a filter element module 30, along with other components such as a water circuit assembly 20, forming an independent module. Different modules are combined and assembled to form the entire modular filtration system. This modular filtration system employs a modular design, dividing the entire system into independent, reusable, and maintainable modules. Each module has a clearly defined function, allowing for independent development, testing, and deployment, and enabling more flexible combinations and adjustments to the overall configuration.

[0049] Based on the above solution, the fixing component 110 of this utility model is installed on the top of the filter element frame 10, and the fixing component 110 fixes the filter element module 30 from the top, combined with Figure 4A , Figure 5A As shown, the front Y-axis of the filter element frame 10 has no solid wall surface, so the filter element module 30 can be placed into the filter element frame 10 from front to back, and the fixing component 110 is fixedly installed on the top of the filter element frame 10 to fix the filter element module 30 on the filter element frame 10.

[0050] The water channel assembly 20 is disposed on the back of the filter element frame 10. The back of the filter element frame 10 (negative Y-axis direction) has a solid structure, and the water channel assembly 20 is fixedly assembled to the back of the filter element frame 10. The back of the filter element frame 10 has a reserved interface channel 140 for the interface of the filter element module 30 to extend out. The interface of the filter element module 30 extends from the interface channel 140 on the back of the filter element frame 10 and connects to the water channel assembly 20.

[0051] In one specific embodiment, combined with Figure 1A As shown, the filter module 30 includes a PCT filter element 310 and an RO filter element 320. The PCT filter element 310 is a composite filter element, and the RO filter element 320 is a reverse osmosis filter element. The PCT filter element 310 includes a PP cotton chamber and a carbon rod chamber, which are independent of each other and each occupy approximately half of the space of the PCT filter element 310. The PP cotton chamber is a pre-filter element, and the carbon rod chamber is a post-filter element.

[0052] It should be noted that filter module 30 is not limited to PCT filter 310 and RO filter 320; other types of filter elements can also be used, such as ultrafiltration membrane (UF) filter elements, KDF filter elements, cotton filter elements, or carbon rod filter elements. The assembly of filter module 30 does not necessarily include an RO filter element; it can be a combination of different types of filter elements.

[0053] After assembly and connection, the water flow sequence is as follows: PP cotton chamber of PCT filter 310, RO filter 320, and carbon rod chamber of PCT filter 310. PCT filter 310 performs physical adsorption and chemical filtration, using high-density PP cotton and carbon fiber / activated carbon to remove residual chlorine, odors, organic matter, and particulate matter. RO filter 320 utilizes a reverse osmosis membrane for physical filtration, with a pore size of only 0.0001 microns, removing almost all impurities such as bacteria, viruses, heavy metals, and dissolved salts. The PCT filter is responsible for "coarse filtration and deodorization," while the RO filter is responsible for "deep purification to produce pure water." Used together, they achieve a safe and palatable water purification effect.

[0054] Combination Figure 2 As shown, the water circuit assembly 20 corresponding to the PCT filter element 310 has four ports. Each chamber of the PCT filter element 310 has one inlet and one outlet port, for a total of four ports for the entire PCT filter element 310. Combined with... Figure 3A As shown, the water circuit assembly 20 corresponding to the RO filter element 320 has three interfaces; as Figure 6 As shown, the RO filter element 320 is equipped with two inlets and one outlet. One inlet is directly connected to the PCT filter element 310, and the other inlet is connected to the booster pump 40. The booster pump 40 pressurizes the water in the PCT filter element 310 and then delivers it to the RO filter element 320.

[0055] In one specific embodiment, combined with Figure 6 As shown, two PCT filter cartridges 310 and one RO filter cartridge 320 are installed. The outlet pipes of the PP cotton chambers of the two PCT filter cartridges 310 are connected in parallel to form a water path to supply water to the RO filter cartridge 320. The outlet pipes of the RO filter cartridge 320 form two parallel branches, which in turn supply water to the carbon rod chambers of the two PCT filter cartridges 310. This configuration provides a large water output and is suitable for commercial environments, meeting the water demand of multi-faucet drinking water platforms.

[0056] In another embodiment, combined Figure 7 As shown, one PCT filter element 310 and one RO filter element 320 are installed. The PP cotton chamber of the PCT filter element 310, the RO filter element 320, and the carbon rod chamber of the PCT filter element 310 are connected in series to deliver water. This configuration can meet the daily water needs of a household and is suitable for a normal household environment.

[0057] In another embodiment, one PCT filter element 310 is provided, and two RO filter elements 320 are provided. The PP cotton chamber of the PCT filter element 310 supplies water to the two RO filter elements 320 in parallel, and the two RO filter elements 320 supply water to the carbon rod chamber of the PCT filter element 310 in parallel.

[0058] In addition, it can be configured with two PCT filter cartridges 310 and two RO filter cartridges 320. One PCT filter cartridge 310 is connected in series with one RO filter cartridge 320 to form a series pipeline, and the other PCT filter cartridge 310 is connected in series with another RO filter cartridge 320 to form a series pipeline. The two pipelines operate independently. Alternatively, the outlets of the two PCT filter cartridges 310 can be connected in parallel to form a pipeline. This pipeline forms two branches in parallel before entering the two RO filter cartridges 320, which respectively supply water to the two RO filter cartridges 320.

[0059] Combination Figure 1C , Figure 3A , Figure 3B , Figure 3C As shown, the sidewalls of the filter element frame 10 are vertically provided with locking protrusions 120. A pair of locking protrusions 120 form locking grooves 121. In the vertical direction, multiple pairs of locking protrusions 120 are provided on the sidewalls of the filter element frame 10, forming multiple locking grooves 121. The locking grooves 121 between two adjacent filter element frames 10 are directly opposite each other and are fixed by U-shaped buckles 101. When the U-shaped buckles 101 are engaged in the locking grooves 121 of the two filter element frames 10, the two sidewalls of the U-shaped buckles 101 prevent the two filter element frames 10 from separating left and right (X-axis), and the two sidewalls of the U-shaped buckles 101 respectively contact the locking protrusions 120 to prevent vertical displacement (Z-axis), thus relatively fixing the two filter element frames 10.

[0060] Combination Figure 3B As shown, a locking notch 102 is provided on the side wall of the filter element frame 10. The locking notch 102 is a notch structure formed by removing a portion of the solid structure from the side wall of the filter element frame 10, creating several U-shaped recesses on the side wall of the filter element frame 10. The locking notch 102 is located between the two locking protrusions 120 that form the locking groove 121. The locking notch 102 avoids the U-shaped buckle 101. When the U-shaped buckle 101 is engaged, it is flush with the edge of the side wall of the filter element frame 10. The upper and lower edges of the locking notch 102 also limit the movement of the U-shaped buckle 101.

[0061] Combination Figure 4B , Figure 5B As shown, at least one filter element frame 10 has a mounting fixing position 130 on its back side. The fixing position 130 has a columnar structure and can be screwed on. The mounting fixing position 130 is used to fix the booster pump 40 and the adapter 50. As different structures can be assembled, different fixing positions 130 can be installed on the back side of different filter element frames 10.

[0062] Combination Figure 1B As shown, a booster pump 40 is installed on the back of the filter frame 10 corresponding to the RO filter element 320, and an adapter 50 is installed on the back of the filter frame 10 corresponding to the PCT filter element 310.

[0063] This utility model also provides a water dispenser, including the above-mentioned modular filtration system. The water dispenser adopts a modular design, which can achieve the above-mentioned technical effects. The water dispenser can use different modules in combination.

[0064] Combination Figure 6 As shown, a combination of dual PCT filter cartridges 310 and a single RO filter cartridge 320 is used. After the source water passes through a constant pressure valve and a low-pressure switch, it is diverted and simultaneously enters the inlet of the pre-filter (PP cotton) of the PCT filter cartridge 310. After passing through the pre-filter, the water flows out of the outlet and is then collected by a solenoid valve and booster pump to supply the RO filter cartridge 320. The RO filter cartridge 320 outputs water to a flow meter and a high-pressure switch. The inlet of the post-filter cartridge (carbon rod) of the PCT filter cartridge 310 provides purified water for use. This configuration provides a large water output, suitable for commercial environments, and meets the water needs of multi-faucet drinking water systems.

[0065] Combination Figure 7 As shown, this system employs a single-unit structure, combining a single PCT filter cartridge 310 and a single RO filter cartridge 320. Source water enters the inlet of the pre-filter (PP cotton) of the PCT filter cartridge 310 through a constant pressure valve and a low-pressure switch. After passing through the pre-filter, the water flows out of the outlet and then into the solenoid valve and booster pump, supplying water to the RO filter cartridge 320. The RO filter cartridge 320 then flows to the inlet of the post-filter (carbon rod) of the PCT filter cartridge 310, from which purified water is supplied for use. This filtration system can meet the daily water needs of a household and is suitable for normal household environments.

[0066] This utility model's modular filtration system breaks down the filter cartridge system into modular components. Depending on the usage environment, suitable subsystems can be selected and assembled, resulting in high versatility. The fixed dimensions facilitate easier system assembly of the assembled subsystems, increasing its portability.

[0067] Modular design makes software systems easier to maintain and upgrade. When modifications or repairs are needed, only specific modules need to be addressed without affecting the entire system. This approach also allows for the updating of individual modules without requiring a complete replacement, improving productivity and reducing costs. The product layout employs a modular design, placing the filter subsystem components before overall assembly, allowing for modular assembly first.

[0068] Because each module is independent, different development teams can work on different modules simultaneously, thus accelerating the overall project development process. This parallel development approach can improve team collaboration efficiency and shorten project delivery time.

[0069] Based on the basic RO and PCT components, this system can be configured with multiple modules or used independently. For example, a module with 2 RO components and 1 PCT component is suitable for applications with a high concentration of inorganic substances. Similarly, a 1 RO component and 2 PCT components solution can be used to effectively filter impurities and microorganisms. Multiple modules can also be combined to meet different application needs.

[0070] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
