Description

Technical Field

[0001] The utility model belongs to the technical field of RO reverse osmosis filtration, and specifically relates to a RO reverse osmosis membrane equipment filtration structure. Background Art

[0002] RO reverse osmosis filtration technology generally means that water flows from the low-concentration side to the high-concentration side. Once the water is pressurized, it will flow from the high-concentration side to the low-concentration side, which is the so-called reverse osmosis principle. Since the pore size of the RO membrane is one millionth of a hair, it is invisible to the naked eye, and bacteria and viruses are 5,000 times larger than it. Therefore, only water molecules can pass through, and other impurities and heavy metals are discharged through the wastewater pipe. Therefore, the process of seawater desalination and astronaut wastewater recycling and treatment all use this method, which is a high-tech artificial kidney outside the body.

[0003] At present, drinking water filters on the market generally adopt RO reverse osmosis membrane filtration structure, which can filter inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses and other impurities in raw water. For example, Chinese utility model patent CN216440356U discloses a filtration structure of RO reverse osmosis membrane of a pure water machine, including a circular plate, one side of which is fixedly connected to a simplified body, the inside of which is provided with a reverse osmosis membrane, and the side of the circular plate close to the simplified body is fixedly connected to a sliding rod. The advantages of this utility model are: Insert the cylinder into the sealing groove, control the ring to slide and rise on the outer surface of the slide rod, and then rotate the bottom plate so that the connecting rod drives the card plate to rotate, so that the card plate is inserted into the slot, so that the positions of the first through hole and the second through hole correspond, and then release the ring, and through the elastic force of the spring, the ring slides and resets on the outer surface of the slide rod, driving the card rod to engage with the first through hole and the second through hole, so that the position of the bottom plate is fixed, ensuring that the filtering structure is easy to disassemble, ensuring that the filter net and the activated carbon filter layer can be cleaned and replaced in time, avoiding affecting the subsequent filtering effect.

[0004] Although the above-mentioned prior art can more conveniently remove the filter screen and the activated carbon filter layer, the water purifier cannot continue to filter water during the removal, resulting in the water purifier being unable to be used during the cleaning process.

Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] In order to solve the problem in the above background technology that the water purifier cannot continue to filter water when dismantled, resulting in the water purifier being unable to be used during the cleaning process, the utility model adopts the following technical solution.

[0016] 2. The flow meter can detect the output flow of filtered water. When the flow is lower than the threshold, it indicates that the first filter or the activated carbon filter layer is clogged. At this time, the drive motor can be automatically started and the electromagnetic three-way valve can be adjusted, making it more convenient to flush the first filter and the activated carbon filter layer.

[0017] 3. The water filtered inside the filter box is transported back to the filter housing through the reflux pipe by the provided delivery pump. The water discharged from the sewage pipe is filtered through the second filter and stored inside the filter box. The delivery pump is started after the water level sensor reaches the threshold. The filtered water can be used for other purposes through the faucet. The second filter can be cleaned by pulling it out, which can save water.

[0018] 4. The rotating connection between the rotating flange and the sealing ring can effectively prevent the internal water from leaking to the outside. BRIEF DESCRIPTION OF THE DRAWINGS
