[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] The application provides a composite electrolysis assembly, which comprises Figure 1 and Figure 2 as shown in the figure, which comprises a water inlet end 10 and a water outlet end 11, the water inlet end 10 is connected to a first pipeline 31, and the first pipeline 31 is connected to the water outlet end 11, a first filter core 2, a first electrolysis module 41 and a reverse osmosis filter core 5 are sequentially arranged on the first pipeline 31, and the first electrolysis module 41 comprises a first electrode 81, a solid electrolyte membrane 82 and a second electrode 83 which are sequentially stacked.

[0021] In the embodiment, water enters from the water inlet end 10, enters the first filter core 2 through the first pipeline 31, and is preliminarily filtered to remove suspended particles and the like in the water, so as to avoid affecting the subsequent electrolysis reaction, for example, avoiding that impurities in the water adhere to the electrode surface of the first electrolysis module 41, thereby affecting the service life of the electrode. After the preliminary filtration, the water is electrolyzed by the first electrolysis module 41, and the water is converted into oxidizing groups with oxidation performance, for example, hydroxyl radicals, oxygen atoms, ozone and the like, which can efficiently kill bacteria, viruses and the like in the water, and are suitable for water purification treatment applied in household and commercial scenes. The water subjected to the electrolytic oxidation treatment is introduced into the reverse osmosis filter core 5 for high-precision filtration, and the core component of the reverse osmosis filter core 5 is a reverse osmosis membrane, which has an extremely small pore size, usually 0.1 nm-10 nm, and can effectively isolate bacteria, viruses, heavy metals and the like in the water, thereby purifying the water. The water purifying device of the application combines electrolysis technology and reverse osmosis technology, and sets an electrolysis unit at the front end of the reverse osmosis filter core 5, so that bacteria, viruses and the like in the water are killed by oxidation in the electrolysis unit, the content of microorganisms in the water is greatly reduced, the water introduced into the reverse osmosis filter core 5 is improved in purity, and therefore, the service life of the reverse osmosis membrane can be greatly prolonged.

[0022] It should be understood that the reverse osmosis filter core 5 is also connected with a drain pipe 9 for discharging wastewater produced by the reverse osmosis filter core 5.

[0023] In order to preliminarily filter raw water, in an embodiment, the first filter core 2 is a pp filter core, so as to filter relatively coarse particulate impurities, sludge, colloids and suspended matters in the water.

[0024] In order to improve the water purification effect, in an embodiment, a second filter core 6 is further arranged on the first pipeline 31, and the second filter core 6 is arranged between the first filter core 2 and the first electrolysis module 41. For example, the second filter core 6 is an activated carbon, and for another example, the second filter core 6 is a composite filter core, such as a chemical filter material composite activated carbon, and a suitable filter core can be installed according to actual needs to perform secondary filtration on raw water.

[0025] In one embodiment, the composite electrolysis assembly of the present application further comprises a second pipeline 32, which is connected with the first pipeline 31, and the second pipeline 32 is provided with a second electrolysis module 42, the first end of the second pipeline 32 is connected between the first filter element 2 and the first electrolysis module 41, and the second end of the second pipeline 32 is communicated to the water outlet end 11.

[0026] Based on the above embodiment, further, the second end of the second pipeline 32 is directly connected to the water outlet end 11, so that the composite electrolysis assembly of the present embodiment can selectively purify in the first pipeline 31 or the second pipeline 32, in the case of good raw water quality or low requirement on the quality of the produced water (such as used in non-drinking daily use scenarios), the second pipeline 32 can be selected to pass in for efficient oxidation purification, and the purified water is produced as daily water, and in the case of poor raw water quality or high requirement on the quality of the produced water, the first pipeline 31 can be selected to pass in, and the electrolysis composite reverse osmosis technology is used to produce sterile purified water as direct drinking water. In the two scenarios, the service life of the reverse osmosis filter element can be prolonged while ensuring effective purification of the water body, and the selection of the water purification path according to the actual demand can effectively reduce the waste water production and be more environmentally friendly.

[0027] In one embodiment, the electrolytic water produced by the first electrolysis module has a concentration of 0.1-1 ppm, and the electrolytic water produced by the electrolysis module has a concentration that is too low to effectively sterilize and disinfect, and if the concentration is too high, the oxidation groups may damage the reverse osmosis membrane in the reverse osmosis filter element, therefore, the electrolytic water with a concentration of 0.1-1 ppm can effectively purify the water body and ensure reliable operation of the entire device.

[0028] In one embodiment, the second pipeline 32 is further provided with a third filter element 7, which is arranged at the front end of the second electrolysis module 42, and in one embodiment, the third filter element 7 is a FOF filter element, which can effectively prevent scale and filter impurities and scale in the water to avoid subsequent scale deposition on the electrode surface of the second electrolysis module 42, affecting the service life thereof.

[0029] In order to improve the water purification effect, for example, the number of the first electrolysis module 41 and / or the second electrolysis module 42 is multiple, and the number of electrolysis assemblies is stacked to increase the concentration of oxidation groups, thereby improving the efficiency and performance of oxidation and degradation.

[0030] In one embodiment, the electrode material of the first electrode 81 and / or the second electrode 83 is one of conductive silicon, conductive diamond, or one of the elements of titanium, platinum, lead, tantalum, iridium, palladium or oxides thereof. In one embodiment, the electrode material of the first electrode 81 and the second electrode 83 is the same, and the electrode conversion between the first electrode 81 and the second electrode 83 can be achieved by changing the current, thereby reducing the problem of scale such as calcium carbonate adhering to the surface of the electrode.

[0031] The first electrode 81 and the second electrode 83 are determined by the power supply / voltage connected thereto.

[0032] The first electrode 81 and the second electrode 83 are connected to the power supply voltage, and the water flowing through the low-voltage electrolysis generates electrolytic water containing hydroxyl radicals, ozone, oxygen atoms and other oxidizing groups, thereby achieving oxidation sterilization and disinfection.

[0033] The application also provides a water purification device comprising the composite electrolysis assembly described in any one of the above embodiments.
