[0002] Most existing water purifiers are fixed integrated units, meaning the primary filter module and the reverse osmosis filter module are fixed in the same frame. The arrangement of these two modules can be flexibly selected according to the required water purification standards, and while this method can effectively filter the water source, the fixed installation dimensions limit the installation space, making it impossible to install the equipment in some locations. Furthermore, in case of product malfunction, it is necessary to disassemble the protective casings of both the primary and reverse osmosis filter modules, resulting in wasted labor and potential safety hazards.

[0003] Therefore, there is an urgent need for a modular filter assembly that can conveniently and specifically disassemble and install filter devices that need to be repaired or replaced, thereby reducing labor costs and improving convenience. Utility Model Content

[0019] It should be noted that the primary filtration device 1 and reverse osmosis filtration device 2 used in this utility model are well-known water filtration devices in the art. The difference lies in the filter element materials used. Specifically, the filter element of the primary filtration device can be a polypropylene / activated carbon / ultrafiltration primary filtration filter element 7, and the reverse osmosis filtration device 2 uses a reverse osmosis membrane filter element 8. Both the primary filtration device and the reverse osmosis filtration device include a housing, a filter element connector located within the housing, and several water source channels opened on the filter element connector. The filter element connector is connected to the filter element, and several water inlets are also provided on the housing corresponding to the water source channels. In other words, the primary filtration device and reverse osmosis filtration device used in this utility model are well-known water filtration device structures in the art, and this utility model will not be described in further detail.

[0020] The modular filter assembly of this utility model is freely combined based on several primary filter devices 1 and several reverse osmosis filter devices 2 connected in series with the primary filter devices 1. The primary filter devices 1 can be connected in series or in parallel. Similarly, the reverse osmosis filter devices 2 can be connected in series or in parallel. The specific structure of the modular filter assembly varies depending on the number of primary filter devices 1 and reverse osmosis filter devices 2, as follows:

[0021] like Figure 1 and Figure 2 As shown, when the primary filter device 1 is a set and the reverse osmosis filter device 2 is also a set, forming a 1+1 modular filter assembly, the primary filter device 1 and the reverse osmosis filter device 2 are connected in series. The housing of the primary filter device 1 is provided with an inlet 3 and an outlet 4, and the housing of the reverse osmosis filter device 2 is provided with a number of inlets 3 (preferably 2), a wastewater outlet 5 and a number of pure water outlets 6 (preferably 2). The number of inlets 3 of the reverse osmosis filter device 2 are connected to the outlet 4 of the primary filter device 1 to form a series connection module.

[0022] When two sets of primary filtration devices 1 and one set of reverse osmosis filtration devices 2 are used, forming a 2+1 modular filtration assembly, the primary filtration devices 1 and reverse osmosis filtration devices 2 are connected in series, while the primary filtration devices 1 can be connected in parallel. Each of the two sets of primary filtration devices 1 has an inlet 3 and an outlet 4 on its shell, while the reverse osmosis filtration device 2 has several inlets 3 (preferably two), wastewater outlets 5, and several pure water outlets 6 (preferably two) on its shell. The inlets 3 of both sets of primary filtration devices 1 are connected to a water source, and the outlets 4 of the two sets of primary filtration devices 1 are combined and connected to several inlets 3 of the reverse osmosis filtration device 1 to form a series-connected modular assembly.

[0023] When two sets of primary filtration devices 1 and one set of reverse osmosis filtration devices 2 are used, forming a 2+1 modular filtration assembly, the primary filtration devices 1 and reverse osmosis filtration devices 2 are connected in series. The primary filtration devices 1 can also be connected in series with each other. Each of the two sets of primary filtration devices 1 has an inlet 3 and an outlet 4 on its shell. The reverse osmosis filtration device 2 has several inlets 3 (preferably two), wastewater outlets 5, and several pure water outlets 6 (preferably two) on its shell. The inlet 3 of the first-stage primary filtration device 1 is connected to the water source, and the outlet 4 of the first-stage primary filtration device 1 is connected to the inlet 3 of the next stage (i.e., the second stage) primary filtration device 1. The outlet of the second-stage filtration device 1 is connected to several inlets 3 of the reverse osmosis filtration device 2, forming a series-connected modular assembly.

The pure water outlets 6 of the first-stage reverse osmosis filtration device 2 can be combined and connected to the inlets 3 of the next-stage reverse osmosis filtration device 2. This allows for parallel connection between several primary filtration devices 1, series connection between several reverse osmosis filtration devices 2, and series connection between primary filtration device 1 and reverse osmosis filtration device 2.

[0025] When two or more primary filtration units 1 and two or more reverse osmosis filtration units 2 are used, the primary filtration units 1 and reverse osmosis filtration units 2 are connected in series. Several primary filtration units 1 can be connected in parallel, and several reverse osmosis filtration units 2 can also be connected in parallel modules. Each primary filtration unit 1 has an inlet 3 and an outlet 4 on its shell, and each reverse osmosis filtration unit 2 has several inlets 3 (preferably two), wastewater outlets 4, and several pure water outlets 5 (preferably two) on its shell. The inlets of the primary filtration units 1 are connected to a water source, and the outlets 4 of the primary filtration units 1 are combined and connected to the inlets 3 of the reverse osmosis filtration units 2, thus realizing parallel connections between primary filtration units 1, parallel connections between reverse osmosis filtration units 2, and series connections between primary filtration units 1 and reverse osmosis filtration units 2.

[0026] When there are two or more primary filtration devices 1 and two or more reverse osmosis filtration devices 2, the primary filtration devices 1 and reverse osmosis filtration devices 2 are connected in series. Several primary filtration devices 1 can be connected in series, and several reverse osmosis filtration devices 2 can be connected in series as modules. Each primary filtration device 1 has an inlet 3 and an outlet 4 on its shell, and each reverse osmosis filtration device 2 has several inlets 3 (preferably two), wastewater outlets 5, and several pure water outlets 6 (preferably two) on its shell. The inlet 3 of the first-stage primary filter 1 is connected to the water source. The outlet of the first-stage primary filter 1 is connected to the inlet 3 of the next-stage primary filter 1, and so on. The outlet 4 of the last-stage primary filter 3 is connected to several inlets 3 of the first-stage reverse osmosis filter 2. Several pure water outlets 5 of the first-stage reverse osmosis filter 2 can be combined and connected to several inlets 3 of the next-stage reverse osmosis filter 2, so as to realize the series connection between several primary filters 1, the series connection between several reverse osmosis filters 2, and the series connection between primary filters 1 and reverse osmosis filters 2.

[0027] When there are two or more primary filtration devices 1 and two or more reverse osmosis filtration devices 2, the primary filtration devices 1 and reverse osmosis filtration devices 2 are connected in series. Several primary filtration devices 1 can be connected in series, and several reverse osmosis filtration devices 2 can be connected in parallel.
