Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis device technology, and in particular to an integrated two-stage reverse osmosis device. Background Technology

[0002] A reverse osmosis water purifier is an integrated two-stage reverse osmosis water purifier that combines microfiltration, adsorption, ultrafiltration, reverse osmosis, ultraviolet sterilization, and ultrapurification technologies to directly convert tap water into ultrapure water. The purified water produced by a reverse osmosis water purifier is fresher, more hygienic, and safer than bottled water.

[0003] A search revealed Chinese Patent Publication No. CN221412432U, which discloses an integrated two-stage reverse osmosis pure water device, belonging to the technical field of reverse osmosis pure water machines. The device includes a mounting base and a filter unit, which is movably connected to the upper surface of the mounting base. The filter unit includes a housing. The beneficial effect of this integrated two-stage reverse osmosis pure water device is that, by setting a fixing groove, a telescopic rod, a spring, a fixing block, and a connecting groove, when it is necessary to replace or clean the small-aperture sieve plate, activated carbon adsorption plate, and filter plate inside the filter unit, the user inserts the side ends of these components into the slots of the fixing block and pushes them to the left. This causes the fixing block to move to the left, compressing the spring. When the fixing block moves to its maximum left position, the bottom of the small-aperture sieve plate, activated carbon adsorption plate, and filter plate is inserted into the connecting groove. Under the elasticity of the spring, the small-aperture sieve plate, activated carbon adsorption plate, and filter plate are pressed together and fixed.

[0004] While the above solution has the advantage of facilitating the loading and unloading of small-aperture sieve plates, activated carbon adsorption plates, and filter plates, in actual use, replacing the filter device requires manual disassembly of the flanges using tools, which is cumbersome and has low replacement efficiency.

[0005] Therefore, there is an urgent need to provide an integrated two-stage reverse osmosis device to solve the above problems. Utility Model Content
