[0002] A reverse osmosis water purifier is a device that uses reverse osmosis membrane separation technology to produce pure water. Its core principle is to apply a certain pressure to force raw water through a selectively permeable reverse osmosis membrane, which retains dissolved salts, colloids, microorganisms, and organic impurities in the water, thereby obtaining highly pure water. It is used in drinking water preparation, food processing, pharmaceutical production, and the electronics industry. It can effectively remove harmful substances from water, improve water quality, meet the demand for high-purity water in different scenarios, and provide a safe and reliable water source for production and daily life.

[0003] A heat-sterilized reverse osmosis water purifier is a device that adds a heat sterilization function to the basic reverse osmosis water purifier. By circulating hot water at a certain temperature inside the system, the high temperature kills bacteria, viruses and microorganisms in the reverse osmosis membrane and pipelines, thereby maintaining the cleanliness and hygiene of the system and avoiding the impact of microbial contamination on the quality of the output water. It is especially suitable for the medical and biological fields where hygiene requirements are high.

[0038] Reference Figure 1 , Figure 2 and Figure 5 The sealing mechanism 3 includes two fixing rings 301, which serve as the mounting base for the sealing structure. The bottoms of the two fixing rings 301 are fixedly connected to the tops of the corresponding filter barrels 4, achieving a stable connection between the fixing rings 301 and the filter barrels 4. Each of the two filter barrels 4 has a sealing groove 302 on its top, which can cooperate with a sealing rubber ring 308 to enhance the sealing performance. Each of the two inlet pipes 5 has a connecting ring 303 fixedly connected to its outer wall. The connecting ring 303 connects the inlet pipe 5 to the fixing rings 301. Each of the two connecting rings 303 has an annular groove 304 on its top, which can accommodate a hollow cylinder. 305, multiple hollow cylinders 305 are fixedly connected to the inner top of the two annular grooves 304. The hollow cylinders 305 can accommodate spring 2 306 and movable cylinder 307. Spring 2 306 is fixedly connected to the inner top of the multiple hollow cylinders 305.

[0039] Both fixing rings 301 have fixing components 309 on their outer walls. The fixing components 309 can strengthen the connection between the connecting ring 303 and the fixing ring 301. The fixing components 309 include multiple upright plates 3091. The upright plates 3091 can support the fixing bolts 3094. One side of the multiple upright plates 3091 is fixedly connected to the left and right sides of the outer wall of the corresponding fixing ring 301, which can realize the fixation of the upright plates 3091 and the fixing ring 301. The top side of the multiple upright plates 3091 is provided with a groove 3092. The groove 3092 can place the horizontal plate 3093. The top left and right sides of the two connecting rings 303 are fixedly connected with horizontal plates 3093. The horizontal plates 3093 can cooperate with the fixing bolts 3094 to achieve fixation. The top of the multiple upright plates 3091 is rotatably connected with the fixing bolts 3094. The fixing bolts 3094 can press the horizontal plates 3093 to enhance the connection stability.

[0040] Specifically, the bottoms of the two fixing rings 301 in the sealing mechanism 3 are respectively fixed to the top of the corresponding filter barrel 4, providing an installation base for the sealing structure. The sealing groove 302 opened on the top of the filter barrel 4 cooperates with the sealing rubber ring 308 to enhance the sealing effect. The connecting ring 303 fixed on the outer wall of the water inlet pipe 5 plays a connecting and supporting role. The ring groove 304 opened on its top is used to install the hollow cylinder 305. The spring 306 fixed on the top of the inner side of the hollow cylinder 305 can provide elastic force for the moving cylinder 307, pushing the sealing ring at the bottom of the moving cylinder 307.

[0041] Reference Figure 2 , Figure 4 and Figure 5Multiple movable cylinders 307 have sliders 6 fixedly connected to their top left and right sides. The sliders 6 can slide within the grooves 7. Multiple hollow cylinders 305 have grooves 7 on their interior left and right sides. The grooves 7 can restrict the movement trajectory of the sliders 6. The protection mechanism 8 includes columns 801, which can support the connecting plate 802. The bottoms of multiple columns 801 are fixedly connected to the four corners of the top of the base plate 1, which can achieve a stable connection between the columns 801 and the base plate 1. The tops of multiple columns 801 are fixedly connected to corresponding... The connecting plate 802 can connect to the column 801 and install the controller 803. The controller 803 is fixedly connected to the bottom left end of the front connecting plate 802. The controller 803 can control the operating status of the equipment. The bottom of the two connecting rings 303 are slidably connected to the inside of the corresponding sealing groove 302, which can enhance the stability of the connection between the connecting ring 303 and the filter barrel 4. The two sealing rubber rings 308 are slidably connected to the inside of the corresponding ring groove 304, which can ensure the smooth movement of the sealing rubber rings 308.

[0042] Specifically, the sliders 6 on the top left and right sides of the multiple movable cylinders 307 cooperate with the sliding grooves 7 opened on the left and right sides inside the multiple hollow cylinders 305 to limit the movement trajectory of the movable cylinders 307 within the hollow cylinders 305, preventing the movable cylinders 307 from shifting or rotating under the action of the spring 306, ensuring that the movable cylinders 307 can drive the sealing rubber rings 308 to accurately fit with the sealing grooves 302, ensuring the sealing effect. In the protection mechanism 8, the bottoms of the multiple columns 801 are respectively fixed at the four corners of the top of the base plate 1, and the tops are connected to the corresponding connecting plates 802 to form a frame structure, which can protect the top and sides of the equipment and prevent external objects from colliding with the filter barrel 4. The bottoms of the two connecting rings 303 are respectively slidably connected to the inside of the corresponding sealing grooves 302, which can enhance the stability of the connection between the connecting rings 303 and the filter barrel 4 and prevent the connecting rings 303 from shaking and affecting the seal.

[0043] Working principle: After the water pump 2102 starts, the water pipe 2103 draws water out through the bottom of the filter tank 4, forming a water flow force that pushes the raw water into the filtration system. When it is necessary to replace or maintain the reverse osmosis membrane 205, the quick-release mechanism 2 facilitates quick operation. The mounting ring 201 is fixed at the bottom of the inlet pipe 5. The connecting block 211 at the top of the mounting bracket 204 is connected to the mounting ring 201. When connected, the moving block 208 on the connecting block 211 moves along the sliding groove 202 and is locked into the slot 203 under the elastic force of the spring 207. In the limiting component 209, the limiting block 2091 slides in the limiting groove 2092 to ensure the stable movement of the moving block 208 and to fix the mounting bracket 204 and the mounting ring 201. When disassembling, press the moving block 208 to compress the spring 207, so that the moving block 208 is disengaged from the slot 203, and the mounting bracket 204 can be removed for easy replacement and installation by the staff.

[0044] Furthermore, when the inlet pipe 5 connects to the filter barrel 4, the connecting ring 303 moves down with the inlet pipe 5. The sealing rubber ring 308 at its bottom first contacts the sealing groove 302 at the top of the filter barrel 4. At this time, the spring 306 in the hollow cylinder 305 in the annular groove 304 at the top of the connecting ring 303 is compressed by the pressure transmitted by the moving cylinder 307, generating a reverse elastic force to push the sealing rubber ring 308 tightly into the sealing groove 302. Then, the fixing component 309 further strengthens the sealing structure, and the horizontal plates 3093 on both sides of the connecting ring 303 move down to the concave part of the vertical plate 3091 on the outer wall of the fixing ring 301. At groove 3092, rotate the fixing bolt 3094 on the top of the vertical plate 3091 to press the bottom of the horizontal plate 3093, and firmly fix the connecting ring 303 and the fixing ring 301. The continuous elastic force of the second spring 306 ensures that the sealing rubber ring 308 is always tightly fitted with the sealing groove 302. The gap is compensated by the spring extension and contraction. The rigid connection between the fixing bolt 3094 and the horizontal plate 3093 prevents the connecting ring 303 from loosening. With double protection, the top of the filter barrel 4 achieves efficient sealing, providing a closed environment for the filtration process of the reverse osmosis membrane 205 and preventing the reduction of purification efficiency caused by raw water leakage.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
