Description

Technical Field

[0001] The utility model mainly relates to the technical field of water purifiers, and specifically relates to a PP cotton melt-blown filter element. Background Art

[0002] A water purifier, also called a water purifier or water purifier, is a water treatment device that deeply filters and purifies water according to the requirements for water use. The water purifier we usually talk about generally refers to a small purifier used for home use. The core components inside are various filter elements that can be disassembled and replaced. The function of the filter element is to capture and filter various impurities in the water body. The more common ones are PP cotton melt-blown filter elements.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] The outer part of the PP cotton meltblown filter in the water purifier is more susceptible to the influence of impurities and pollutants in the water and becomes dirty than the inner part. This is because the outer part of the meltblown filter is at the outermost layer of the water flow and is the first to contact the impurities and pollutants in the incoming water. Therefore, during use, the outermost part of the filter will be contaminated first. The contamination will cause the filter mesh pores in the meltblown filter to be blocked, affecting the normal passage of water and the filtering effect, resulting in a shorter service life of the entire filter element, reducing the filtering efficiency of the water purifier, and the current PP cotton meltblown filter element needs to be replaced as a whole.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0029] See attached Figure 1-4A PP cotton melt-blown filter element comprises a filter element cylinder 1, the top of the filter element cylinder 1 is connected to an upper cover plate 2, a magnetic suction component 3 is plugged into the upper cover plate 2, the four sides of the upper cover plate 2 are provided with first arc grooves 4, the first arc grooves 4 are slidably connected to an external filter shell 5, the bottom of the filter element cylinder 1 is connected to a lower cover plate 6, the middle of the lower cover plate 6 is connected to a liquid outlet 7, a liquid outlet groove 8 is provided in the middle of the filter element cylinder 1, and a secondary filter element 9 is matched and connected in the liquid outlet groove 8. The filter element can be installed inside the filter shell. When working, water flows through the external filter shell 5 for preliminary filtration, and then passes through the magnetic suction component 3, the magnetic suction component 3, and the magnetic suction component 3. The suction component 3 absorbs the magnetic material in the water flow, and finally enters the filter element cylinder 1. The filter element cylinder 1 is made of PP cotton melt-blown material, and finally passes through the secondary filter element 9 in the middle to filter again, and is discharged through the liquid outlet 7. The external filter shell 5 can capture large particles of impurities, thereby increasing the service life of the internal filter element cylinder 1, and after a period of use, the first arc groove 4 can be removed upward and replaced with a new external filter shell 5, thereby increasing the service life of the internal filter element cylinder 1 and preventing the outermost pollutants of the water flow from quickly causing the pores of the filter screen of the internal filter element cylinder 1 to be blocked, resulting in the replacement of the entire filter element.

[0030] The magnetic attraction component 3 includes a support ring 31, a second arc groove 32 is opened on the outer side of the support ring 31, and the second arc groove 32 is the same as the first arc groove 4. Magnetic columns 33 are arranged at intervals at the bottom of the support ring 31, a corresponding first connecting hole 34 is opened on the upper cover plate 2, and a corresponding concave positioning groove 35 is opened on the lower cover plate 6. The magnetic column 33 passes through the first connecting hole 34 and is inserted into the concave positioning groove 35. A plurality of magnetic columns 33 can be provided according to the size of the filter element cylinder 1, and magnetic particles can be captured when water flows through, thereby further improving the service life of the internal filter element cylinder 1. The support ring 31 is detachably connected to the upper cover plate 2 by screws. After the magnetic attraction component 3 is pulled out of the first connecting hole 34, the externally adsorbed substances can be manually removed and inserted again for reuse.
