Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a filter element structure for faucets. Background Art

[0002] Faucets are commonly used in bathrooms and kitchens and are a type of hardware accessories that people often use in daily life. As people's living standards continue to improve, people pay more and more attention to health, and people gradually pay more attention to the hygiene of daily water use. For this reason, filter elements are usually installed directly on faucets to filter water. For families that already have faucets installed, filter elements are usually installed at the water outlet for filtering. Existing filter elements usually filter water sources through filters with different apertures. However, as time goes by, impurities filtered out of the filter nets are likely to clog the filter nets, thereby affecting the water output efficiency. It is usually necessary to remove the filter element and take out each filter net for cleaning, which makes the cleaning process of the filter element cumbersome and inconvenient for people to use. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a filter element structure for a faucet, which has the function of facilitating the cleaning of a filter screen inside the filter element.

[0012] The utility model is further configured as follows: a water outlet net is provided at the bottom of the shell, four connecting holes are evenly distributed on the water outlet net, and four clamping blocks matching with the connecting holes are evenly distributed on the lower end of the shell.

[0013] By adopting the above technical solution, the water outlet net can be fixed through the cooperation of the clamping block and the connecting hole, so that the shell and the water outlet net are easy to disassemble and assemble, and it is convenient for people to install and disassemble the upper filter net and the lower filter net.

[0014] The utility model is further configured as follows: a limiting ring fixed to the inner wall of the shell is provided on the upper side of the upper positioning groove, the limiting ring abuts against the upper side of the upper filter plate, and a positioning ring is fixed to the upper end of the water outlet net.

[0015] By adopting the above technical scheme, a limiting ring fixed to the inner wall of the shell is provided on the upper side of the upper sealing groove, the limiting ring abuts against the upper side of the upper filter plate, a positioning ring is fixed at the upper end of the water outlet net, the positioning ring abuts against the lower side of the lower filter net, and the upper end of the upper filter plate is limited by the limiting ring, so that when the first cleaning block cleans the upper filter plate, the upper filter plate is not easy to shake upwards, which is convenient for cleaning the mesh holes on the upper filter plate, and the positioning block can make the lower filter plate not easy to shake downwards, so that when the second cleaning block cleans the lower filter plate, the lower filter plate is not easy to shake downwards, which is convenient for cleaning the mesh holes on the lower filter plate.

[0016] In summary, the utility model has the following beneficial effects:

[0017] When it is necessary to clean the upper filter screen and the lower filter screen in the shell, the operating ring on the outer side of the sliding shell can drive the cleaning plate to move up and down through the magnetic force, so that the mesh holes of the upper filter plate are cleaned by the first cleaning block, and the mesh holes on the lower filter screen are cleaned by the second cleaning block, so that there is no need to disassemble the upper filter plate and the lower filter plate when cleaning the mesh holes on the upper filter plate. The cleaning steps are simple and convenient, and it is easy for people to use in daily life. BRIEF DESCRIPTION OF THE DRAWINGS
