When RO reverse osmosis membrane 332 needs to be installed, it is inserted into membrane housing 331. RO reverse osmosis membrane 332 will push pressing ring 33501 to move. The movement of pressing ring 33501 causes limiting rods 3359 to slide within circular through hole 3358 and movable groove 3357. The sliding of limiting rods 3359 will press against the rear end of spring 3350. When the RO reverse osmosis membrane 332 is fully inserted into the membrane housing 331, the membrane plug 333 can be used to seal the membrane housing 331. When the RO reverse osmosis membrane 332 needs to be disassembled, the membrane plug 333 is removed from the inner wall of the membrane housing 331. At this time, the rebound force of the spring 3350 will push the limiting rod 3359 to move. The movement of the limiting rod 3359 will drive the pressing ring 33501 to move, pushing one end of the RO reverse osmosis membrane 332 out of the membrane housing 331, thereby pulling out the RO reverse osmosis membrane 332 and completing the disassembly of the RO reverse osmosis membrane 332, which improves the disassembly and assembly efficiency.
[0028] Please see Figure 5The fixing structure 32 includes a fixing plate 321, the rear side of which is fixedly connected to the front side of the mounting plate 31. Mounting grooves 322 are provided on both the left and right sides of the front side of the fixing plate 321. Connecting grooves 323 are provided on both the left and right sides of the lower front side of the fixing plate 321. A circular movable hole 1, penetrating into the left connecting groove 323, is provided on the left side of the inner wall of the right connecting groove 323. A fixing rod 324 is movably connected to the inner wall of the circular movable hole 1. Conical teeth 325 are fixedly connected to both ends of the fixing rod 324. A circular movable hole 2, penetrating into the mounting groove 322, is provided on the top of the inner wall of the connecting groove 323. A connecting shaft 326 is movably connected to the inner wall of the circular movable hole 2. Conical teeth 327 are fixedly connected to the bottom of the connecting shaft 326. The outer wall of conical tooth 327 meshes with the outer wall of conical tooth 325. A bidirectional threaded rod 328 is fixedly connected to the top of the connecting shaft 326. A support sleeve 329 is movably connected to the middle position of the outer wall of the bidirectional threaded rod 328. The outer wall of the support sleeve 329 is movably connected to the inner wall of the mounting groove 322. Two symmetrical sliders 320 are threadedly connected to the outer wall of the bidirectional threaded rod 328. A connecting plate 3201 is fixedly connected to the front side of the slider 320. A clamping groove 3202 is opened on the side of the upper and lower connecting plates 3201 that are close to each other. Anti-slip pads 3203 are fixedly connected to the two inclined surfaces of the inner wall of the clamping groove 3202. The outer wall of the anti-slip pad 3203 is movably connected to the outer wall of the membrane shell 331. A stepper motor is fixedly connected to the right side of the bottom of the inner wall of the right connecting groove 323. The stepper motor 3204 has a fixed shaft 3205 connected to its output end. A fixed sleeve 3206 is movably connected to the outer wall of the shaft 3205. A conical tooth 3207 is fixedly connected to the left end of the fixed sleeve 3206. The outer wall of the conical tooth 3207 meshes with the outer wall of the conical tooth 327. Starting the stepper motor 3204 causes the shaft 3205 to rotate, which in turn drives the conical tooth 3207 to rotate. This rotation of the conical tooth 3207 drives the right conical tooth 327, causing the right conical tooth 325 to rotate. The rotation of the right conical tooth 325 then drives the fixed rod 324 to rotate, causing the left conical tooth 325 to rotate. This, in turn, drives the left conical tooth 325 to rotate. The rotation of the first conical tooth 325 causes the second conical tooth 327 on the left to rotate, which in turn causes the connecting shaft 326 to rotate. The rotation of the connecting shaft 326 simultaneously drives the bidirectional threaded rod 328 to rotate. The rotation of the bidirectional threaded rod 328 causes the two sliders 320 on its outer wall to move closer or further apart within the mounting groove 322. As the sliders 320 move closer, the connecting plates 3201 move closer together, causing the clamping groove 3202 to clamp and fix the membrane housing 331, increasing the stability of the membrane housing 331 during use. When it is necessary to disassemble the membrane housing 331, the stepper motor 3204 is started in reverse, causing the two clamping grooves 3202 to move away from each other.By releasing the clamping and fixing of the diaphragm housing 331, it can be removed for replacement or repair. The operation is simple and convenient. The anti-slip pad 3203 increases the friction between the clamping groove and the diaphragm housing 331, preventing the diaphragm housing 331 from falling off. It also allows for the fixing of diaphragm housings 331 of different sizes, improving the adaptability of the device. The threaded connections between the connecting pipe 35, the T-shaped three-way pipe 36, the L-shaped bend 37, and the L-shaped mounting pipe 38 allow for the replacement of these components according to different diaphragm housings 331, further enhancing the practicality of the device.
[0029] Working principle:
[0030] When the RO reverse osmosis membrane 332 needs to be installed, insert the RO reverse osmosis membrane 332 into the membrane housing 331. The RO reverse osmosis membrane 332 will push the pressing ring 33501 to move. The movement of the pressing ring 33501 will cause the limiting rod 3359 to slide inside the circular through hole 3358 and the movable groove 3357. The sliding of the limiting rod 3359 will compress the spring 3350. When the RO reverse osmosis membrane 332 is fully inserted into the membrane housing 331, the membrane plug 3 can then be removed. 33. The membrane housing 331 is sealed. When it is necessary to disassemble the RO reverse osmosis membrane 332, the membrane plug 333 is removed from the inner wall of the membrane housing 331. At this time, the rebound force of the spring 3350 will push the limiting rod 3359 to move. The movement of the limiting rod 3359 will drive the pressing ring 33501 to move, pushing one end of the RO reverse osmosis membrane 332 out of the membrane housing 331, thereby pulling out the RO reverse osmosis membrane 332 and completing the disassembly of the RO reverse osmosis membrane 332, which improves the disassembly and assembly efficiency.
[0031] The stepper motor 3204 is activated, causing the rotating shaft 3205 to rotate, which in turn drives the conical gear 3207 to rotate. The rotation of the conical gear 3207 drives the right conical gear 327, which in turn drives the right conical gear 325. The rotation of the right conical gear 325 drives the fixed rod 324, which in turn drives the left conical gear 325. This rotation of the left conical gear 325 then drives the left conical gear 327, which in turn drives the connecting shaft 326 to rotate. The rotation of the connecting shaft 326 simultaneously drives the bidirectional threaded rod 328 to rotate. The rotation of the bidirectional threaded rod 328 causes the two sliders 320 on its outer wall to move closer or further apart on the inner wall of the mounting groove 322. As the sliders 320 move closer together, the connecting plates 3201 also move closer together. As the connecting plates 3201 move closer together, the clamping grooves 3202 clamp and fix the diaphragm housing 331, increasing the stability of the diaphragm housing 331 during use. When it is necessary to disassemble the diaphragm housing 331, the stepper motor 3204 is started in reverse, causing the two clamping grooves 3202 to move away from each other, releasing the clamping and fixing of the diaphragm housing 331, allowing the diaphragm housing 331 to be taken out for replacement or maintenance. The operation is simple and convenient. The anti-slip pad 3203 increases the friction between the clamping grooves and the diaphragm housing 331, preventing the diaphragm housing 331 from falling off, and can fix diaphragm housings 331 of different sizes, improving the adaptability of the device. The threaded connection between the connecting pipe 35, the T-shaped three-way pipe 36, the L-shaped bend pipe 37, and the L-shaped mounting pipe 38 allows the device to replace the connecting pipe 35, the L-shaped bend pipe 37, and the L-shaped mounting pipe 38 according to different diaphragm housings 331, improving the practicality of the device.
