The second mounting groove 20 provides mounting space for the fixed cover 21 and the sealing plate 24 thereon and the impurity collecting tank 49, wherein the sealing plate 24 is tightly fitted with the inner bottom wall of the first mounting groove 19 through the rubber sealing ring 25 to ensure the sealing. The through hole 26 on the outer wall of the impurity collecting tank 49 can receive the water flow input through the pipeline by the rotary joint 50, and the impurity filter 34 can effectively filter impurities in the water, realizing the purification of the water quality. The design structure is compact, which is conducive to improving the efficiency of water flow transmission and purification. The setting of the fixed cover 21, the first slide groove 27, the first slider 28 and the first limiting hole 29 is conducive to providing a reliable locking mechanism for the stable installation of the fixed cover 21.

At the same time, the water pump 35 installed on the top of the purification box 1 is connected to the fixed sleeve 18 and the feed pipe 36 through a pipeline, forming an efficient water circulation purification system. The water pump 35 can return the purified water to the purification box 1 for further treatment or utilization, thereby improving the utilization rate and purification efficiency of water resources. By arranging a partition 37 and a high-pressure pump 38 inside the purification box 1, combined with the first reverse osmosis membrane 40 in the first installation pipe 39 and the second reverse osmosis membrane 42 in the second installation pipe 41, efficient multi-stage purification of water quality is achieved. The first reverse osmosis membrane 40 preliminarily removes most of the impurities and harmful substances in the water, while the second reverse osmosis membrane 42 removes more impurities and harmful substances in the water. High filtration accuracy further deeply purifies the water quality, ensuring the high purity and safety of the effluent, which is conducive to improving the purification efficiency and purification effect. Through the setting of intelligent components such as the water level sensor 44, the processor module 48, and the control panel 45, the water level sensor 44 is used to monitor the water level changes in the purification box 1 in real time to ensure the stability of the water level during the purification process. The processor module 48 intelligently adjusts the working status of the water pump 35 and the high-pressure pump 38 according to the water level signal to optimize the purification efficiency. The control panel 45 provides an intuitive user interface, which not only supports the flexible setting of purification parameters and real-time monitoring of the purification status, but also can receive and display fault alarm information to enhance the reliability and safety of the system. The display screen 46 clearly displays the current purification status, water quality indicators and system operation parameters.The operation button 47 allows the user to manually control the start and stop of each component and adjust the working parameters, thus achieving full control over the purification process.
