AI Technical Summary
When the frequency and amount of water used by users are unstable, the cleaning mechanism of the reverse osmosis water purification system starts frequently and the amount of bubble water is insufficient, resulting in poor cleaning effect and waste of water resources.
A reverse osmosis water purification system was designed, including a water purification mechanism, a water storage tank, and a cleaning mechanism. The system stores concentrated water and prepares bubble water when needed. The bubble water is used to clean the drainage pipes. The flow direction of concentrated water and pure water is controlled by a liquid level sensor and a switching valve to avoid frequent start-up of the cleaning mechanism.
This technology avoids frequent activation of the cleaning mechanism when user water usage is unstable, ensuring a sufficient amount of bubble water to clean drainage pipes, reducing water waste, and improving cleaning effectiveness and user experience.
