Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a portable water purification equipment capable of automatic backwashing. Background Art

[0002] Simply put, water purification equipment is equipment for producing purified water, and purified water is widely used in: drinking, chemical, medical, breeding, planting, food, beverages, etc. Most of them use reverse osmosis technology. Reverse osmosis is a physical method without phase change at room temperature to desalinate and remove salt from salt water, so as to improve the overall treatment.

[0003] The patent application of Jianjingsuo in the publication (announcement) number: CN214437142U discloses a portable water purification device that is easy to replace the internal circulation filter screen, including a body, a soft water chamber and an internal circulation network. A first outer cylinder is installed on the left side of the interior of the body, and the soft water chamber is installed at the lower end of the interior of the first outer cylinder. A transmission pipe is connected to the right side of the lower end of the soft water chamber, and a first threaded connecting pipe is arranged on the right side of the upper end of the transmission pipe. A desalination chamber is connected to the right side of the first threaded connecting pipe, and a filter element is arranged on the right side of the desalination chamber, and a second outer cylinder is installed on the right side of the filter element. The portable water purification device that is easy to replace the internal circulation filter screen is provided with a soft water chamber, and the soft water chamber forms a sliding structure with the first outer cylinder through a second slide groove and a second slider. The installation of the soft water chamber can soften the water after filtration and desalination to ensure the safety of drinking water. In use, the second slide groove and the second slider serve as disassembly parts of the soft water chamber and have good stability.

[0004] Although the above solution does not require frequent shutdown for replacement of the internal circulation network during use, which not only saves a lot of time and improves work efficiency, but the impurities accumulated on the filter structure often clog the filter holes, resulting in a decrease in purification effect. For this reason, we propose a portable water purification device that can automatically backwash. Utility Model Content
