Description

Technical Field

[0001] The utility model relates to the technical field of pure water equipment, in particular to pure water production equipment with disinfection and sterilization functions. Background Art

[0002] Pure water equipment mainly uses reverse osmosis membrane technology. Its working principle is to exert a certain pressure on water so that water molecules and ionic mineral elements pass through the reverse osmosis membrane, while most of the inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. dissolved in the water cannot pass through the reverse osmosis membrane, thereby strictly separating the pure water that has permeated and the concentrated water that cannot permeate. The pore size on the reverse osmosis membrane is only 0.0001 microns, while the diameter of viruses is generally 0.02-0.4 microns, and the diameter of ordinary bacteria is 0.4-1 microns.

[0003] However, the above-mentioned equipment has the following technical problems in actual use: (1) When filtering sewage, the sewage is directly introduced into the pure water production equipment, which increases the working intensity of the reverse osmosis membrane. When the sewage contains large particles of impurities, it will cause clogging of the reverse osmosis membrane, thereby reducing the filtering effect and affecting the service life of the reverse osmosis membrane. (2) After long-term use of the pure water equipment, bacteria will breed in its pipelines, which will cause the produced pure water to contain bacteria, affecting the quality of pure water production and cannot be used directly.

[0004] Therefore, a pure water production device with disinfection and sterilization functions is proposed. Utility Model Content

A retaining structure is provided on the top of the pretreatment box 1, and the retaining structure contacts the sealing cover 9. A pre-filtering structure is provided in the pretreatment box 1, and a disinfection structure is provided in the sterilization tank 13.
