Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a filter element of a water purifier. Background Art

[0002] Since tap water is only simply filtered and disinfected at the water plant, there are still many substances harmful to the human body in the water, such as rust, mud, colloids and other particulate matter, bacteria, odor, pesticide residues, residual chlorine, heavy metal ions, etc.; and the tap water transported to households through long-distance pipelines will also be contaminated by rust and aging of the pipelines and the algae and bacteria that grow therein. Therefore, the tap water entering households needs to be purified and filtered twice. The most common measure currently taken is the water purifier.

[0003] After long-term use, scale will be generated inside the water purifier. However, most water purifiers in the existing technology do not perform scale prevention treatment when filtering tap water. Scale will affect the filtering effect of the filter element and shorten its service life, so the filter element needs to be replaced frequently, which reduces practicality and increases usage costs.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 5 As shown, the embodiment of the present invention provides a filter element for a water purifier, comprising:

[0025] The shell 1 is provided with a water outlet pipe 2 at the bottom of the shell 1, a water inlet 4 is provided on the sealing cover 3, and the water inlet 4 is provided through the positioning bucket 9. The top of the shell 1 is threadedly connected with the sealing cover 3. The top of the sealing cover 3 is fixedly provided with a sealing gasket 18, which is set against the top of the shell 1. The sealing gasket 18 plays a sealing role between the sealing cover 3 and the shell 1. A limiting plate 5 is fixedly provided on the outside of the shell 1. The limiting plate 5 is set against the sealing cover 3. The limiting plate 5 plays a role in limiting the sealing cover 3. A filter element body 6 is provided in the shell 1. A sealing ring 16 is provided on the filter element body 6. The shape of the sealing ring 16 is as follows Figure 5 As shown, it is provided with a convex arrangement and is tightly arranged with the filter element body 6 and the housing 1. The sealing ring 16 plays a sealing role between the filter element body 6 and the inner wall of the housing 1. A clamp 17 is provided on the sealing ring 16. The clamp 17 is a prior art. The working principle is similar to the clamping hoop of the rubber cap. By rotating the corresponding screw, the corresponding iron ring can be tightened, thereby tightening the sealing ring 16. By loosening the clamp 17, the sealing ring 16 can be removed, which is convenient for replacement when damaged. A positioning component is provided between the housing 1 and the filter element body 6;

[0026] The positioning assembly includes a clamping column 8, a positioning bucket 9 and a positioning cylinder 7. A sleeve is fixedly provided on the inner bottom of the housing 1. The clamping column 8 is fixedly provided at the bottom of the filter element body 6. The clamping column 8 extends into the sleeve and is provided in a coordinated manner. The positioning bucket 9 is fixedly provided on the inner top of the sealing cover 3. The positioning cylinder 7 is fixedly provided on the top of the filter element body 6. The positioning cylinder 7 and the positioning bucket 9 are set against each other. The positioning bucket 9 can correct the positioning cylinder 7 to keep the positioning cylinder 7 vertical to avoid deviation and affect the sealing performance. A plurality of notches are provided on the positioning cylinder 7. The notches serve as a water passage, so that water can enter the housing 1 through the notches.

[0027] The scale inhibition assembly includes a holding box 10, multiple holding boxes 11, a cover plate 12, and multiple clamping blocks 15. The holding box 10 is placed on the filter element body 6. Multiple partition plates 11 are fixedly arranged in the holding box 10. A plurality of scale inhibition sheets are filled between the multiple partition plates 11. The partition plates 11 can evenly separate the multiple scale inhibition sheets so that they can more fully contact with water, thereby improving the scale inhibition effect. The scale inhibition sheet is a prior art, and the scale inhibition sheet is a FOF scale inhibition sheet. The scale inhibition sheet can effectively prevent the formation and accumulation of scale;

[0028] The cover 12 is arranged on the top of the containing box 10, and the positioning tube 7 passes through the containing box 10 and the cover 12 and is movably arranged so that the containing box 10 can be sleeved on the positioning tube 7. A number of through holes 13 are provided on the containing box 10 and the cover 12 to facilitate the entry of water. A plurality of spring pieces 14 are fixedly provided on the outside of the containing box 10, and a plurality of card blocks 15 are respectively fixed on the inner sides of the plurality of spring pieces 14. The tops of the plurality of card blocks 15 are all arranged in an inclined surface, and the plurality of card blocks 15 are all arranged in cooperation with the cover 12. The cover 12 squeezes the inclined surface of the card block 15, which can push the card block 15 outward and bend the spring piece 14.

[0029] The detailed working process of this utility model is as follows:

[0030] 1. During installation, first insert the filter element body 6 into the housing 1 and squeeze the sealing ring 16 so that the sealing ring 16 is tightly against the inner wall of the housing 1 and the filter element body 6. At the same time, insert the clamping column 8 into the sleeve 8, and then put the container 10 containing the scale inhibitor on the positioning cylinder 7. Finally, tighten the sealing cover 3 and calibrate the filter element body 6 through the positioning bucket 9.

[0031] 2. When adding or replacing the scale-inhibiting sheets, the staff can first unscrew the sealing cover 3, then take out the containing box 10, and then bend the four card blocks 15 outward to separate them from the cover plate 12, and then take out the cover plate 12. After removing the cover plate 12, the scale-inhibiting sheets can be added or replaced, and then the cover plate 12 is covered, and the multiple card blocks 15 are squeezed and pushed outward to bend the corresponding spring pieces 14. When the cover plate 12 moves to the bottom of the multiple card blocks 15, the multiple card blocks 15 can be reset under the action of the corresponding spring pieces 14, clamping the cover plate 12. Finally, the containing box 10 is replaced and the sealing cover 3 is tightened.
