Technical Field

[0001] The utility model relates to the field of ultrapure water filtration, in particular to a filtering device for facilitating ultrapure water filtration. Background Art

[0002] Ultrapure water is a type of water with extremely high chemical purity. In theory, it contains only water molecules and almost no other substances. Ultrapure water is usually prepared in a variety of purification methods, such as distillation, deionization, reverse osmosis, etc., to remove impurities and pollutants in the water. When filtering ultrapure water, filtering equipment is required.

[0003] In the existing technology, the filtration device includes a shell and a reverse osmosis membrane core located inside the shell. The reverse osmosis membrane core is used to filter water. However, the strength of the reverse osmosis membrane core is not strong. When the filtration device is bumped, its shell will deform and produce pits, thereby squeezing the reverse osmosis membrane core inside, thereby affecting the normal use of the reverse osmosis membrane core and making it not durable enough.
