Description

Technical Field

[0001] The utility model relates to the technical field of rural drinking water filtration, in particular to a small-scale water purification and filtration device for rural drinking water. Background Art

[0002] With the improvement of living standards of rural residents, the requirements for drinking water are getting higher and higher. Nowadays, many rural families will install a water purification device at home, install it in a suitable location, and then connect the water inlet with the tap water inlet pipe. The tap water is then filtered through the filter element inside the water purification device so that it can meet the drinking standards, thereby greatly facilitating the daily drinking water needs of rural residents.

[0003] After searching, the existing patent (Announcement No.: CN215939264U) discloses an integrated rural safe drinking water purification device, including a top plate, a fixed seat is fixedly installed on the lower surface of the top plate, a shell is fixedly installed on the lower surface of the fixed seat, a filter element is arranged inside the shell, and a special-shaped rod is fixedly installed on the outer surface of the filter element. The integrated rural safe drinking water purification device is divided into an outer shell and an inner tank structure by changing the structure of the filter layer. The internal filter element is fixedly connected to the bottom plate of the outer connecting rod through the spring at the bottom, and the outer connecting rod is slidably connected through the special-shaped protrusion inside it. The two connecting rods are fixed in position by a limit block. The above structures cooperate. When the filter element needs to be replaced, just press the limit block, it will be retracted by the spring, and the spring at the bottom of the filter element works to drive the connecting rod to slide out, so as to achieve the purpose of quickly replacing the filter element and improve its work efficiency.

[0004] However, in the above scheme, it is inconvenient to initially filter and discharge sewage, and the water filtration is all done by the filter element. Since some houses of rural residents are far apart, the laid water delivery pipelines are long, and when drinking water, some impurities inside the pipeline will be transported together. These larger impurities will cause a greater burden on the filter element, making the filter element need to be replaced more frequently, which is not conducive to the daily use of rural residents.

[0005] In view of this, the utility model proposes a small water purification and filtering device for rural drinking water. Utility Model Content
