Description

TECHNICAL FIELD

[0002] An application patent with the Chinese patent number CN201711309452.8 discloses a filter core mounting seat for a waterway reversible type pure water machine, which comprises a waterway plate body, an upper mounting plate and a lower mounting plate. The upper mounting plate, the waterway plate body and the lower mounting plate are arranged from top to bottom and are integrally fused together. However, defects such as air holes, misaligned edges and incomplete fusion may occur during the production process. Meanwhile, the mold cost is high and difficult to maintain. In addition, a tooling verification of the waterway plate performance is required in the later stage, which leads to high overall manufacturing cost of the product and is not conducive to product promotion.

[0003] Therefore, relevant technical personnel have carried out research and development. For example, an application patent with the Chinese patent number CN201921412194.0 discloses a water system, which comprises a spliced waterway and a filter core assembly. The spliced waterway comprises a first module, a second module, a third module and a fourth module. Each module is provided with a waterway pipeline. The filter core assembly comprises a pre-filter core, an RO filter core and a post-filter core. The first module and the second module are fixedly connected and clamped and fixed, and are connected with the pre-filter core. The second module and the third module are fixedly connected and clamped and fixed, and are connected with the RO filter core. The third module and the fourth module are fixedly connected and clamped and fixed, and are connected with the post-filter core. The above-mentioned water system is spliced by a plurality of modular waterway plates. The mold forming of each module is simple, the mold cost is low and easy to maintain, the assembly process between the modules is simple, and the modules are easy to disassemble and assemble. However, the above-mentioned water system still has the following defects:

[0004] 1. The spliced waterway is spliced by four modules, and the number of components is large, and the production cost is high.

[0005] 2. The adjacent modules are only fixed by screws, and the connection stability is poor, so that the spliced overall waterway in the form of a flat plate is prone to twisting and deformation, and thus the sealing property between the modules is affected.

[0006] 3. The filter core and the module are only connected by a water inlet, and there is no auxiliary component for positioning between them, so that the connection stability is poor, and the filter core and the module are prone to separation due to vibration during use or carrying, and thus water leakage occurs.

[0007] 4. The electromagnetic valve, the NTC thermistor, the booster pump and the TDS water quality sensor and other water purification electronic components need a fifth module for assembly, so that the overall spliced waterway is poor in integrity, the space utilization rate is low, and the spliced waterway occupies a large space of the water purification machine after assembly.

[0008] Therefore, it is necessary to further improve. SUMMARY
