Description

Technical Field

[0001] The present invention relates to the technical field of pre-water purifiers, in particular to the technical field of multifunctional pre-water purification systems. Background Art

[0002] The existing tap water is usually centrally supplied by municipal water companies and has been processed. However, due to the lack of necessary maintenance and cleaning during the long-term use of water pipelines, it is easy to seep, scale and rust in the water pipelines, which in turn causes the growth of bacteria and algae in the water pipelines, causing secondary pollution of tap water during the transportation process, and ultimately making it difficult for tap water to fully meet various health and safety indicators.

[0003] A pre-water purifier is a device that can filter the water used in the whole house, and is generally installed at the front end of the pipe. The filter element is the main functional component of the water purifier. It can use a variety of internal filter materials to remove harmful microorganisms, heavy metal elements, rust, sand and mud and other impurities in the tap water to ensure the safety of the water used in the whole house, such as the method for making a composite filter element and a carbon rod disclosed in the invention patent with announcement number CN105236640B and a filter element filtering device for beauty use disclosed in the invention patent with announcement number CN205933463U. With the gradual improvement of living standards, people's requirements for water purifiers are gradually increasing. However, the existing filter element can often only filter out impurities in tap water, and cannot improve the nutritional components of tap water, which is difficult to meet the needs of consumers. Secondly, in order to achieve multiple filtering functions, the existing filter element usually combines multiple filtering materials together, and at the same time, in order to control the filtering order, multiple waterways are set to control the filtering order. However, this leads to a complex water purification structure of the filter element, a large volume, troublesome assembly and high production cost. Summary of the invention

[0018] Beneficial effects of the present invention:

[0019] 1) By connecting the core shell with the unconnected water purification channel and wastewater channel with the core shaft, MIX ultrafine membrane and mineral particles to form a MIX ultrafine core body, the core shaft wound with the MIX ultrafine membrane can be used to filter tap water, and finally the filtered clean water first contacts with the mineral particles along the water purification channel and is mixed with various minerals required by the human body before being discharged, while the filtered wastewater is directly discharged along the wastewater channel. The overall structure is simple, easy to process and prepare, with high water treatment efficiency, and can independently complete the addition of minerals to meet consumers' mineral nutrition needs for tap water;

[0020] 2) By using the outer cylinder, base cover and base barrel to form the core shell together, not only can a clean water channel located in the middle and a wastewater channel arranged around the clean water channel be formed, but also a shell cavity with a larger volume can be formed above the clean water channel to store mineral particles, which can increase the storage capacity of mineral particles while ensuring the high-flux flow of clean water and wastewater, thereby ensuring the dissolution of mineral nutrients;

[0021] 3) The composite core is composed of a shell ring, zeolite, PP cotton tube, carbon rod and core head, and a pre-purification channel and a post-purification channel which are not connected to each other are arranged in the core head, so that the tap water can be discharged from the pre-purification channel after the pre-treatment of zeolite and PP cotton tube, and then fully contact with the carbon rod during the process of flowing through the post-purification channel to complete the post-purification treatment. The overall structure is compact, the volume is small, and it is easy to process and assemble;

[0022] 4) By connecting the inner guide cover, the middle guide cover, the outer guide cover, the support barrel and the guide tube to form a core head, not only can the pre-purification channel and the post-purification channel be separated from each other to avoid the mixing of tap water before and after the two treatments, but also a relatively spacious water flow channel can be provided while keeping the whole machine occupying a small area, thereby effectively improving the filtration efficiency;

[0023] 5) By installing sponge pads at the water inlet and outlet of the water purification channel and the water inlet and outlet of the ring cavity, the sponge pads can be used to effectively prevent mineral particles from flowing out of the shell cavity of the water purification channel and prevent zeolite from flowing out of the ring cavity of the shell ring, thereby ensuring the water quality of the purified water outlet and the pre-water outlet, and extending the service life of the MIX ultra-fine membrane and PP cotton tube.

[0052] Working process of the present invention:

[0053] After the tap water is pre-filtered by the composite filter element, it is first transported to the MIX ultra-fine filter element for filtration and mineral addition under the action of the increasing pump 8, and then sent back to the composite filter element to complete the post-filtration, and finally directly flows out of the tap after being sterilized by the LED sterilization tube 9. In addition, the wastewater generated by the MIX ultra-fine filter element is directly discharged through the wastewater pipe.

[0054] For MIX ultra-fine filter elements, see Figure 2 When in use, tap water is first fed into the MIX ultrafine filter bottle 1 along the water inlet 11 of the bottle body, and then filtered through the MIX ultrafine membrane 22. Figure 5 As shown in the flow path of purified water in the figure, in the process of upward flow, tap water can first penetrate the MIX ultra-fine membrane 22 layer by layer from the outside to the inside to filter out harmful microorganisms, heavy metals, rust, sand and mud and other impurities, and enter the shaft body passage 211 along each shaft body through hole 212, and the purified water produced by filtration can flow into the shell cavity surrounded by the base cover 232 and the base barrel 233 along the shaft body passage 211 and mix with the mineral particles 24 to increase the various minerals required by the human body, and then be discharged through the cover tube 2321 and the bottle body direct drinking water outlet 12. Figure 5 The wastewater generated by filtration of the MIX ultrafine membrane 22 flows along the gaps between the outer cylinder 231 and the base barrel 233 and between the outer cylinder 231 and the base cover 232 and is finally discharged through the wastewater outlet hole 13 of the bottle body.

[0055] The filtration process of the composite filter element is divided into a pre-purification process and a post-purification process.

[0056] For pre-purification, see Fig.11 When in use, tap water is first fed into the composite filter bottle 3 along the front water inlet 31 of the bottle body, and then flows out of the composite filter bottle 3 along the front water outlet 32 ​​of the bottle body, thereby completing the pre-purification process. Fig.11 As shown in the pre-purification flow path, tap water first enters the annular cavity along the water inlet of the cavity and mixes with the zeolite 42 to absorb harmful elements such as heavy metals, and then flows into the annular gap between the shell ring 41 and the PP cotton tube 43, and then gradually penetrates the PP cotton tube 43 to the middle to remove mud, rust, suspended matter, residual chlorine and odor, and finally enters the pre-purification channel along the cotton tube channel and leaves the composite core 4.

[0057] For post-cleaning procedures, see Fig.13 When in use, tap water is first fed into the composite filter bottle 3 along the rear water inlet 33 of the bottle body, and then flows out of the composite filter bottle 3 along the rear water outlet 34 of the bottle body, thereby completing the rear purification process. Fig.13As shown in the post-purification flow path, tap water flows in sequence through the gap between the inner guide cover 451 and the middle guide cover 452, the gap between the carbon rod 44 and the support barrel 454, the carbon filter channel, the rod channel and the cover channel, and during the passage through the carbon filter channel, the carbon rod 44 can improve the taste and absorb foreign colors and odors.
