AI Technical Summary
Existing water inlet treatment systems for water heaters suffer from single-function filter cartridges that cannot meet the overall water quality improvement requirements, copper-based materials that are not synergistic with mineralization/scale inhibition components, scale inhibitors that cause concentration fluctuations when added, and a lack of slow-release technology.
The multifunctional composite filtration device adopts a modular series structure, including dechlorination, antibacterial, mineralization and scale inhibition units. It utilizes sodium alginate microcapsules to encapsulate polyepoxysuccinic acid FOF scale inhibitor, strontium-rich ore modules and copper-based metal mesh to achieve four-stage synergistic filtration. Sodium thiosulfate/activated carbon neutralizes residual chlorine, copper-based metal mesh kills microorganisms, strontium-rich ore increases strontium content, and FOF scale inhibitor slowly releases polyaspartic acid salt to inhibit scale.
It achieves water output from the water heater that meets direct drinking standards, with a total bacterial count ≤50 CFU/mL, a 90% reduction in limescale, and extends the equipment's lifespan by more than three times.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, specifically a multifunctional composite filter device for a household water heater inlet pretreatment system. Background Technology
[0002] There are three major defects in the existing water inlet treatment of water heaters: 1. Single-function filter cartridges (such as those that only remove scale) cannot meet the comprehensive water quality improvement requirements; 2. Copper-based materials are mostly used in terminal faucets and are not used in conjunction with mineralization / scale inhibition components; 3. Direct addition of scale inhibitors leads to concentration fluctuations and lacks slow-release technology. In view of this, in-depth research was conducted to address the above problems, which led to this case. Utility Model Content
[0003] The purpose of this invention is to provide a multifunctional composite filtration device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A multifunctional composite filtration device is characterized by comprising a connecting end and a housing that are threadedly connected to each other, wherein a composite filter is installed inside the housing.
[0006] In a further preferred embodiment of the present invention, the composite filter comprises a dechlorination unit, an antibacterial unit, a mineralization unit, and a scale inhibition unit sequentially filled inside.
[0007] Further optimization of this utility model is that the scale inhibition unit is an FOF scale inhibitor module, which uses sodium alginate microcapsules to encapsulate polyepoxysuccinic acid.
[0008] Further optimization of this utility model is that the mineralization unit is a strontium-rich ore module with a pH-responsive chitosan membrane on its surface.
[0009] In a further preferred embodiment of this invention, the antibacterial unit is a copper-based metal mesh, the surface of which is treated with nano-etching to form micron-level antibacterial protrusions.
[0010] In a further preferred embodiment of this invention, the dechlorination unit is a module internally loaded with sodium thiosulfate-based composite filter media or an activated carbon fiber layer.
[0011] In a further preferred embodiment of this invention, the composite filter is provided with a flow guide groove on its exterior.
[0012] In a further preferred embodiment of this utility model, one end of the connecting end is an external thread end, the other end is an internal thread end, and there is also an installation end for connecting and installing the composite filter.
[0013] In a further preferred embodiment of this invention, a filter screen is installed inside the connecting end.
[0014] In a further preferred embodiment of this invention, a ferrite magnetic sheet is installed at the top of the inner end of the connecting end.
[0015] Compared with existing technologies, the beneficial effects of this utility model are:
[0016] In this utility model, the four-stage unit adopts a modular series structure, with the water flow direction in sequence as follows: dechlorination → antibacterial → mineralization → scale inhibition. Through a four-stage synergistic filtration mechanism: (1) sodium thiosulfate / activated carbon rapidly neutralizes residual chlorine; (2) copper-based metal mesh kills microorganisms and releases trace amounts of copper ions; (3) strontium-rich ore increases the strontium content in the water to 0.5-2 mg / L; (4) FOF scale inhibitor carrier continuously releases polyaspartic acid salt to inhibit scale. The device enables the water output from the water heater to meet the direct drinking standard (total bacterial count ≤50 CFU / mL, scale reduction of 90%), extending the equipment life by more than 3 times.
