Description

Technical Field

[0001] This application relates to the field of water purifier technology, and in particular to a smart direct drinking water machine with a combined multi-stage membrane purification system. Background Technology

[0002] Current drinking water purification technologies are widely used in homes, businesses, and industries. Common purification technologies include activated carbon adsorption, reverse osmosis membrane filtration, and ultraviolet sterilization. These technologies perform well in fixed locations such as home water purifiers, but in mobile scenarios such as outdoors, in vehicles, or on ships, space constraints and environmental variations make the size, energy consumption, and adaptability of traditional purification equipment major bottlenecks.

[0003] In existing technologies, drinking water purification typically employs a single purification technology, such as portable activated carbon filters or small reverse osmosis devices. Activated carbon filters are low in cost but have limited purification effects and cannot remove heavy metals and microorganisms; reverse osmosis devices have good purification effects but are bulky, energy-intensive, and require frequent filter replacements. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a smart direct drinking water machine with a combined multi-stage membrane purification system.

[0005] The intelligent direct drinking water machine with combined multi-stage membrane purification provided in this application adopts the following technical solution: A combined multi-stage membrane purification intelligent direct drinking water machine includes a mounting frame, a multi-stage purification module, a heating module, a sterilization module, and a delivery module. The multi-stage purification module, heating module, sterilization module, and delivery module are all mounted on the mounting frame. The multi-stage purification module includes a pre-filter, a reverse osmosis membrane, and a post-activated carbon filter. The heating module includes a heating element and a thermostat; the heating element is fixed to the water outlet of the multi-stage purification module, and the thermostat is mounted on the side of the heating element. The delivery module includes a water pump and a water pipe; the water pump is installed between the multi-stage purification module and the heating module, and the water pipe connects each module. The sterilization module includes an ultraviolet lamp, which is fixed to the inner wall of the water pipe.

[0006] By adopting the above technical solution, water enters the multi-stage purification module through the water pump and water pipeline of the delivery module. The pre-filter removes large particulate impurities, the reverse osmosis membrane removes heavy metals and microorganisms, and the post-activated carbon filter improves the taste, thus achieving water filtration and purification. Then, the water enters the heating module through the water pipeline. The thermostat controls the opening and closing of the electric heating element to achieve high-temperature disinfection of the water. At the same time, during the water transportation process in the water pipeline, the water can pass through the sterilization module in the water transportation path, namely the ultraviolet lamp tube, for ultraviolet sterilization. This achieves multi-stage, multi-directional filtration, sterilization, and disinfection, ensuring the hygiene and drinking safety of the direct drinking water.

[0007] Optionally, the pre-filter, the reverse osmosis membrane, and the post-activated carbon filter are all enclosed in a water purification cylinder, through which water flows.

[0008] By adopting the above technical solution, the water purifier can facilitate water filtration and prevent dust, bacteria and other impurities from coming into contact with the water and affecting the water quality during the filtration or purification process.

[0009] Optionally, the water purification cylinder is divided into a first section, a second section, and a third section; the pre-filter, the reverse osmosis membrane, and the post-activated carbon filter are all disposed on the second section, and the second section between the first section and the third section is a detachable structure; the multi-stage purification module is provided with a switching module; the switching module is connected to the second section and is used for replacing the pre-filter, the reverse osmosis membrane, and the post-activated carbon filter.

[0010] By adopting the above technical solution, the second section is separated from the first and third sections using a switching module, while the pre-filter, reverse osmosis membrane and post-activated carbon filter are installed in the second section. Therefore, the switching module can disassemble the second section for easy replacement.

[0011] Optionally, the second cylinder section includes an upper pressure cylinder, a lower pressure cylinder, and a replacement cylinder; the upper pressure cylinder is located within the first cylinder section, the lower pressure cylinder is located within the third cylinder section, and the replacement cylinder is located between the upper pressure cylinder and the lower pressure cylinder, and abuts against the upper pressure cylinder and the lower pressure cylinder; the upper pressure cylinder, the lower pressure cylinder, and the replacement cylinder are all connected to the switching module.

[0012] By adopting the above technical solution, the switching module separates the upper pressure cylinder and the lower pressure cylinder from the replacement cylinder, thereby enabling the switching module to remove the replacement cylinder between the first cylinder section and the third cylinder section, so as to achieve convenient replacement.

[0013] Optionally, both the first and third cylindrical sections are provided with a fixed sealing ring; the top and bottom of the upper pressure cylinder, the lower pressure cylinder, and the replacement cylinder are provided with a clamping sealing ring; the clamping sealing ring at the top of the upper pressure cylinder abuts against the fixed sealing ring of the first cylindrical section, the clamping sealing ring at the bottom of the upper pressure cylinder abuts against the clamping sealing ring at the top of the replacement cylinder; the clamping sealing ring at the top of the lower pressure cylinder abuts against the clamping sealing ring at the bottom of the replacement cylinder, and the clamping sealing ring at the bottom of the lower pressure cylinder abuts against the fixed sealing ring of the third cylindrical section.

[0014] By adopting the above technical solution, when the upper pressure cylinder abuts against the replacement cylinder, the upper pressure cylinder ensures stable sealing with the first cylinder section through the fixed sealing ring and the pressing sealing ring. When the lower pressure cylinder abuts against the replacement cylinder simultaneously, the lower pressure cylinder ensures stable sealing with the third cylinder section through the pressing sealing ring and the fixed sealing ring of the third cylinder section. Furthermore, the pressing effect between the pressing sealing rings achieves sealing between the upper pressure cylinder and the replacement cylinder, and between the replacement cylinder and the lower pressure cylinder, thereby achieving stable water flow and filtration effect.

[0015] Optionally, the switching module includes an opening / closing drive unit, a sliding rail, a sliding part, a threaded part, a lifting part, a screw-in part, and a switching part; the opening / closing drive unit is connected to the mounting bracket; the sliding rail is installed vertically on the mounting bracket; the sliding part is slidably connected to the sliding rail, and the sliding rail has pivoting parts at both ends; the threaded part is pivotally connected to the sliding rail at both ends through the pivoting parts, and one end passes through the pivoting parts and is connected to the opening / closing drive unit; the screw-in part is installed on the sliding part and screwed to the threaded part; the lifting part is connected to the screw-in part and is connected to the upper pressure cylinder and the lower pressure cylinder; the switching part is pivotally connected to the threaded part, and the replacement cylinder is connected to the switching part.

[0016] By adopting the above technical solution, the opening and closing drive unit drives the threaded part to rotate along the pivot part, causing the threaded part to drive the sliding part to move along the sliding rail. The threaded part is connected to the upper pressure cylinder and the lower pressure cylinder, thereby driving the upper pressure cylinder and the lower pressure cylinder to separate from the replacement cylinder. The replacement cylinder is connected to the switching part, preventing the replacement cylinder from falling off. After the upper pressure cylinder and the lower pressure cylinder are separated, it rotates and disengages with the switching part, thus achieving the function of convenient replacement.

[0017] Optionally, the threaded portion has two sets of external threads in opposite directions. Each set of external threads has a set of threaded portions and a sliding portion. The two sets of threaded portions extend out of the lifting portion and are connected to the upper pressure cylinder and the lower pressure cylinder in sequence. The switching portion is connected to the replacement cylinder.

[0018] By adopting the above technical solution, since the two sets of external threads on the threaded part are opposite, when the threaded part rotates, it can drive the two sets of threaded parts to move in opposite directions or towards each other, thereby realizing that the upper pressure cylinder and the lower pressure cylinder connected by the threaded part move in opposite directions or towards each other. When the upper pressure cylinder and the lower pressure cylinder move in opposite directions, the upper pressure cylinder and the lower pressure cylinder are respectively released from the pressing state of the replacement cylinder. When the upper pressure cylinder and the lower pressure cylinder move towards each other, they respectively press the replacement cylinder, thereby achieving a sealing effect.

[0019] Optionally, the switching part includes a pivot ring, a switching frame, and a receiving ring; the pivot ring is sleeved on the threaded part and pivotally connected to the threaded part; the switching frame is installed on the pivot ring; the receiving ring is installed on the switching frame, and the second cylindrical section is engaged with the receiving ring.

[0020] By adopting the above technical solution, after the replacement cylinder is received by the receiving ring, the load-bearing object of the replacement cylinder is changed according to the pressing state of the upper and lower pressure cylinders. When the load-bearing object is the upper and lower pressure cylinders, the pivot ring does not rotate with the threaded part. When the load-bearing object is the receiving ring, the pivot ring can rotate with the threaded part under the influence of pressure, thereby achieving the effect of rotating the replacement cylinder for replacement.

[0021] Optionally, a single switching frame and a receiving ring form a group, and the pivot ring is provided with several groups of the switching frame and the receiving ring.

[0022] By adopting the above technical solution, when a replacement cylinder on a single receiving ring needs to be replaced, the switching frame rotates the receiving ring and the replacement cylinder out, and simultaneously drives another receiving ring and the replacement cylinder to rotate to the upper pressure cylinder and the lower pressure cylinder. After pressing, the replacement can be completed. Using multiple replacement cylinders for interval replacement can extend the manual replacement time and also ensure a stable supply of filtration effect.

[0023] Optionally, the pivot ring has a toothed ring at its bottom; the mounting bracket also has a switching drive unit, which has a gear and the gear meshes with the toothed ring.

[0024] By adopting the above technical solution, the switching drive unit can drive the pivot ring to rotate through gears and gear rings, thereby driving all switching frames, receiving rings and changing cylinders to rotate, so as to achieve the effect of replacing the clean changing cylinder.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Water enters the multi-stage purification module through the water pump and water pipeline of the delivery module. The pre-filter removes large particulate impurities, the reverse osmosis membrane removes heavy metals and microorganisms, and the post-activated carbon filter improves the taste, thus achieving water filtration and purification. Then, it enters the heating module through the water pipeline. The thermostat controls the opening and closing of the electric heating element to achieve high-temperature disinfection of the water. At the same time, during the water transportation process, the water can pass through the sterilization module in the water transportation path, namely the ultraviolet lamp tube, for ultraviolet sterilization. This achieves multi-stage and multi-directional filtration, sterilization and disinfection, ensuring the hygiene and drinking safety of the direct drinking water. 2.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0033] This application discloses an intelligent direct drinking water machine with a combined multi-stage membrane purification system.

[0034] A smart water purifier with a combined multi-stage membrane purification system is shown. The outer casing provides packaging and protection, preventing dust, bacteria, and other fine particles from entering the interior. To better illustrate the internal structure, the outer casing is hidden in the illustration. Figure 1 As shown.

[0035] The intelligent direct drinking water machine of this application includes a mounting frame 1, a multi-stage purification module 2, a heating module 3, a sterilization module 4, and a conveying module 5; the multi-stage purification module 2, the heating module 3, the sterilization module 4, and the conveying module 5 are all installed on the mounting frame 1. The mounting frame 1 is connected to the outer shell and serves as a supporting skeleton for the overall module, with multiple branches extending from it to ensure the stable installation of multiple modules.

[0036] The multi-stage purification module 2 includes a pre-filter 21, a reverse osmosis membrane 22, and a post-activated carbon filter 23. The pre-filter 21 is used to remove large particulate impurities, the reverse osmosis membrane 22 is used to remove heavy metals and microorganisms, and the post-activated carbon filter 23 is used to improve the taste. The pre-filter 21, the reverse osmosis membrane 22, and the post-activated carbon filter 23 are all connected by a conveying module 5.

[0037] Heating module 3 includes an electric heating element and a thermostat. The electric heating element is fixed to the water outlet of the purification module, and the thermostat is installed on the side of the electric heating element. The electric heating element and the thermostat can controllably heat the purified water and further sterilize and disinfect the water by utilizing the effect of high-temperature disinfection.

[0038] The sterilization module 4 includes an ultraviolet lamp tube, which is fixed to the inner wall of the pipe of the delivery module 5. The ultraviolet lamp tube is located in the water delivery path, so the water can be continuously disinfected during delivery, further improving the safety and hygiene of the drinking water.

[0039] The delivery module 5 includes a water pump and a water delivery pipe. The water pump is installed between the multi-stage purification module 2 and the heating module 3. The water delivery pipe connects each module, thereby using the water pump to provide water pressure supply, and then delivering water to each module through the delivery pipe to achieve water purification and direct drinking. At the end of the delivery pipe, there are two water taps for users to drink directly or fill up water.

[0040] It also includes a water storage tank and a control module. The water storage tank is located next to the multi-stage purification module 2 and is supplied with water through a delivery pipeline. The control module provides control commands for heating time, water pressure provided by the water pump, etc. The control module can be a small controller.

[0041] Specifically, water enters the multi-stage purification module 2 through the water pump and water delivery pipeline of the delivery module 5. The pre-filter 21 removes large particulate impurities, the reverse osmosis membrane 22 removes heavy metals and microorganisms, and the post-activated carbon filter 23 improves the taste, thus achieving water filtration and purification. Then, the water enters the heating module 3 through the water delivery pipeline. The thermostat controls the opening and closing of the electric heating element to achieve high-temperature disinfection of the water. At the same time, during the water delivery process, the water can be sterilized by ultraviolet light through the sterilization module 4, i.e., the ultraviolet lamp tube, in the water delivery path. This achieves multi-stage and multi-directional filtration, sterilization and disinfection, ensuring the hygiene and drinking safety of the direct drinking water.

[0042] Furthermore, the pre-filter 21, reverse osmosis membrane 22, and post-activated carbon filter 23 are all enclosed in a water purification cylinder 6. Water flows through the water purification cylinder 6, which serves as the outer shell for the pre-filter 21, reverse osmosis membrane 22, and post-activated carbon filter 23. After the pre-filter 21, reverse osmosis membrane 22, and post-activated carbon filter 23 are installed inside the water purification cylinder 6, the water flows through the pre-filter 21, reverse osmosis membrane 22, and post-activated carbon filter 23 for filtration and purification before flowing to the heating module 3. Water supply pipes can be installed at the top and bottom of the water purification cylinder 6 to ensure the circulation of water. The water purification cylinder 6 facilitates water filtration and prevents dust, bacteria, and other impurities from contacting the water and affecting the water quality.

[0043] Among them, the pre-filter 21, the reverse osmosis membrane 22 and the post-activated carbon filter 23 are all wrapped by the water purification cylinder 6. Therefore, there are three water purification cylinders 6, which are arranged in sequence to facilitate water purification and transportation.

[0044] In some embodiments, reference Figure 2 As shown, the water purification cylinder 6 is divided into a first cylinder section 61, a second cylinder section 62, and a third cylinder section 63. The pre-filter 21, the reverse osmosis membrane 22, and the post-activated carbon filter 23 are all located on the second cylinder section 62. The second cylinder section 62 between the first cylinder section 61 and the third cylinder section 63 is a detachable structure, allowing the second cylinder section 62 to be removed from the first cylinder section 61 and the third cylinder section 63. This enables the replacement of the pre-filter 21, the reverse osmosis membrane 22, and the post-activated carbon filter 23, avoiding the situation where the pre-filter 21, the reverse osmosis membrane 22, and the post-activated carbon filter 23 filter out too many impurities and thus reduce the filtration effect after long-term use.

[0045] After the second section 62 is disassembled, an opening appears between the first section 61 and the third section 63. When the second section 62 is installed, the opening is filled.

[0046] An electronic valve is installed at the top of the first section 61 and at the bottom of the third section 63. When it is necessary to replace the pre-filter 21, reverse osmosis membrane 22 and post-activated carbon filter 23 on the second section 62, the electronic valve closes the first section 61 and the third section 63 at the same time, so that there is no interference with the water flow during the replacement process.

[0047] The multi-stage purification module 2 is equipped with a switching module 7. The switching module 7 is used to separate the second section 62 from the first section 61 and the third section 63. Therefore, the switching module 7 is connected to the second section 62 and is used to replace the pre-filter 21, the reverse osmosis membrane 22 and the post-activated carbon filter 23, so as to facilitate replacement while maintaining the filtration and purification effect.

[0048] Further reference Figure 3As shown, the second section 62 includes an upper pressure cylinder 621, a lower pressure cylinder 622, and a replacement cylinder 623. The upper pressure cylinder 621 is located inside the first section 61, and the lower pressure cylinder 622 is located inside the third section 63. The upper pressure cylinder 621 can slide along the first section 61, and the lower pressure cylinder 622 can slide along the third section 63. The replacement cylinder 623 is located between the upper pressure cylinder 621 and the lower pressure cylinder 622, and abuts against the upper pressure cylinder 621 and the lower pressure cylinder 622. That is, when the upper pressure cylinder 621 moves along the first section 61 and abuts against the top of the replacement cylinder 623, and the lower pressure cylinder 622 moves along the third section 63 and abuts against the bottom of the replacement cylinder 623, the three abut against each other. The pre-filter 21, the reverse osmosis membrane 22, and the post-activated carbon filter 23 are disposed inside the replacement cylinder 623. When both the upper pressure cylinder 621 and the lower pressure cylinder 622 are separated from the replacement cylinder, the replacement cylinder 623 loses its abutting function.

[0049] The upper pressure cylinder 621, the lower pressure cylinder 622, and the replacement cylinder 623 are all connected to the switching module 7. The switching module 7 moves the upper pressure cylinder 621 and the lower pressure cylinder 622 while fixing the replacement cylinder 623. This ensures that the replacement cylinder 623 will not fall off after it is no longer pressed by the upper pressure cylinder 621 and the lower pressure cylinder 622. The replacement cylinder 623 can then be removed from the gap opening using the switching module 7 for replacement.

[0050] Specifically, the switching module 7 separates the upper pressure cylinder 621 and the lower pressure cylinder 622 from the replacement cylinder 623, so that the switching module 7 can remove the replacement cylinder 623 from between the first cylinder section 61 and the third cylinder section 63 to achieve convenient replacement.

[0051] Furthermore, a fixed sealing ring 64 is provided in both the first cylinder section 61 and the third cylinder section 63, and a pressing sealing ring 624 is provided at the top and bottom of the upper pressure cylinder 621, the lower pressure cylinder 622 and the replacement cylinder 623. The fixed sealing ring 64 is fixed in position within the first cylinder section 61 and the third cylinder section 63 and cannot be moved, while the pressing sealing ring 624 can move with the upper pressure cylinder 621 or the lower pressure cylinder 622.

[0052] When the compression sealing ring 624 at the top of the upper pressure cylinder 621 abuts against the fixed sealing ring 64 of the first cylinder section 61, the compression sealing ring 624 at the bottom of the upper pressure cylinder 621 simultaneously abuts against the compression sealing ring 624 at the top of the replacement cylinder 623. At the same time, the compression sealing ring 624 at the top of the lower pressure cylinder 622 also simultaneously abuts against the compression sealing ring 624 at the bottom of the replacement cylinder 623, and the compression sealing ring 624 at the bottom of the lower pressure cylinder 622 simultaneously abuts against the fixed sealing ring 64 of the third cylinder section 63. The upper pressure cylinder 621, the replacement cylinder 623, and the lower pressure cylinder 622 form a closed water conveying environment to achieve stable water flow and filtration effect.

[0053] When it is necessary to remove the replacement cylinder 623 containing the pre-filter 21, reverse osmosis membrane 22 and post-activated carbon filter 23 for replacement, the switching module 7 moves the upper pressure cylinder 621 along the first cylinder section 61 and the lower pressure cylinder 622 along the third cylinder section 63, thereby releasing the replacement cylinder 623 and allowing for replacement.

[0054] In some embodiments, reference Figure 4 As shown, the switching module 7 includes an opening and closing drive unit 71, a sliding rail 72, a sliding part 73, a threaded part 74, a lifting part 75, a screw connection part 76, and a switching part 77. The opening and closing drive unit 71 is connected to the mounting bracket 1. The opening and closing drive unit 71 adopts a drive motor. The drive motor can be connected to the mounting bracket 1 with a support bracket, or it can be installed on the housing. The installation position can be determined according to the design requirements.

[0055] The sliding rail 72 is installed vertically on the mounting frame 1. The sliding part 73 is slidably connected to the sliding rail 72. The sliding rail 72 has pivot parts 721 at both ends. The pivot parts 721 can be pivot bearings or pivot holes to achieve the pivoting effect.

[0056] The threaded portion 74 is pivotally connected to the sliding rail 72 at both ends via the pivot portion 721, and one end passes through the pivot portion 721 and is connected to the opening and closing drive portion 71. The threaded portion 74 can be a screw or lead screw, which can pivot along the pivot portion 721. The opening and closing drive portion 71 can drive the threaded portion 74 to rotate along the pivot portion 721.

[0057] The threaded part 76 is installed on the sliding part 73 and is threaded to the threaded part 74. The threaded part 76 can be a nut or a fixing structure with a threaded hole. The sliding part 73 can be a slider. The slider can slide along the sliding rail 72 and can also provide a limit for the threaded part 76, so that the threaded part 74 can be driven by the opening and closing drive part 71 to drive the threaded part 76 and the sliding part 73 to move along the sliding rail 72.

[0058] The lifting part 75 can be a lifting frame. After the lifting part 75 is connected to the screw connection part 76, the screw connection part 76 moves along the sliding rail 72 and simultaneously drives the lifting part 75 to move. The lifting part 75 is also connected to the upper pressure part and the lower pressure part, thereby driving the upper pressure cylinder 621 and the lower pressure cylinder 622 to move, so as to achieve the function of separating or pressing the replacement cylinder 623.

[0059] The switching part 77 is pivotally connected to the threaded part 74, and the changing cylinder 623 is connected to the switching part 77. An annular limiting groove can be provided on the threaded part 74, and the switching part 77 is located in the annular limiting groove, so that the switching part 77 can pivot along the threaded part 74 without falling off the threaded part 74.

[0060] When the threaded part 74 rotates, due to the pivotal connection between the switching part 77 and the threaded part 74, the threaded part 74 cannot affect the rotation of the switching part 77. Since the switching part 77 is connected to the replacement cylinder 623, the replacement cylinder 623 is subjected to the pressure of the upper pressure cylinder 621 and the lower pressure cylinder 622, so the switching part 77 will not rotate. When the upper pressure cylinder 621 and the lower pressure cylinder 622 are disengaged from the contact range of the replacement cylinder, the replacement cylinder 623 presses down on the switching part 77. The switching part 77 rotates with the threaded part 74 and can be completely disengaged from the upper pressure cylinder 621 and the lower pressure cylinder 622. The user can then remove and replace the replacement cylinder 623 on the switching part 77.

[0061] Furthermore, the threaded portion 74 has two sets of external threads in opposite directions. Each set of external threads has a set of threaded connection portion 76 and sliding portion 73. The two sets of threaded connection portions 76 extend into lifting portions 75 and are connected to the upper pressure cylinder 621 and the lower pressure cylinder 622 in sequence. The switching portion 77 is connected to the replacement cylinder 623. Since the two sets of external threads on the threaded portion 74 are opposite, when the threaded portion 74 rotates, it can drive the two sets of threaded connection portions 76 to move in opposite directions or towards each other. This allows the upper pressure cylinder 621 and the lower pressure cylinder 622 connected by the threaded connection portions 76 to move in opposite directions or towards each other. When the upper pressure cylinder 621 and the lower pressure cylinder 622 move in opposite directions, the upper pressure cylinder 621 and the lower pressure cylinder 622 are respectively released from the pressing state of the replacement cylinder 623. When the upper pressure cylinder 621 and the lower pressure cylinder 622 move towards each other, they respectively press the replacement cylinder 623, thereby achieving a sealing effect.

[0062] Furthermore, refer to Figure 5 As shown, the switching part 77 includes a pivot ring 771, a switching frame 772, and a receiving ring 773. The pivot ring 771 is sleeved on the threaded part 74 and pivotally connected to the threaded part 74, so that the pivot ring 771 can rotate with or not rotate with the threaded part 74 during rotation. The switching frame 772 is installed on the pivot ring 771, and the receiving ring 773 is installed on the switching frame 772. The second cylinder section 62 is engaged with the receiving ring 773. After the receiving ring 773 receives the sliding cylinder, the second cylinder section 62 can be switched onto the threaded part 773. The pivot ring 771 is fixed in position by the switching bracket 772, so that the pivot ring 771 cannot rotate with the rotation of the threaded part 74. When the upper pressure cylinder 621 and the lower pressure cylinder 622 no longer press the replacement cylinder 623, the replacement cylinder 623 presses down on the receiving ring 773 and the switching bracket 772, so that the pivot ring 771 is subjected to pressure and can rotate with the threaded part 74, thereby achieving the effect of rotating the replacement cylinder 623 out of the upper pressure cylinder 621 and the lower pressure cylinder 622 for replacement.

[0063] The receiving ring 773 is composed of two elastic semi-circular rings, and a retrieval port is provided between the two semi-circular rings. The replacement cylinder 623 can be taken out through the retrieval port. When the receiving ring 773 receives the replacement cylinder 623, it can press against the lower surface of the compression sealing ring 624 at the top of the replacement cylinder 623 to achieve the receiving effect.

[0064] Furthermore, a single switching frame 772 and a receiving ring 773 form a group, and several groups of switching frames 772 and receiving rings 773 are provided on the pivot ring 771. When several groups of switching frames 772 and receiving rings 773 are provided, a set of replacement cylinders 623 can be provided on each receiving ring 773. When the replacement cylinder 623 on a single receiving ring 773 needs to be replaced, the switching frame 772 rotates the receiving ring 773 and the replacement cylinder 623 out, and simultaneously drives another receiving ring 773 and the replacement cylinder 623 to rotate to the upper pressure cylinder 621 and the lower pressure cylinder 622. After pressing, the replacement can be completed. Using multiple replacement cylinders 623 for interval replacement can extend the manual replacement time and also ensure a stable supply of filtration effect.

[0065] Furthermore, the pivot ring 771 has a toothed ring 774 at its bottom, and the mounting bracket 1 also has a switching drive unit 78. The switching drive unit 78 has a gear 79, and the gear 79 meshes with the toothed ring 774. The switching drive unit 78 can be a switching motor, which can be mounted on the mounting bracket 1 or on the inner wall of the housing. The gear 79 is connected to the drive end of the switching motor, so that the switching motor can drive the gear 79 to rotate. At the same time, the pivot ring 771 has a toothed ring 774 that meshes with the gear 79 at its bottom, so the pivot ring 771 can be driven to rotate by the switching motor.

[0066] The pivot ring 771 can rotate to drive the replacement cylinder 623 to rotate, which is a more stable method than the method of using the replacement cylinder 623 to press down the switching frame 772 by gravity. This method can ensure the accuracy and stability of the switching. At the same time, the meshing of the gear ring 774 and the gear 79 can prevent the pivot ring 771 from rotating randomly, further improving the positional stability of the replacement cylinder 623.

[0067] Sensors can be installed on the outer wall of the mounting frame 1 or the first cylinder section 61. The sensors can be photoelectric sensors or infrared sensors. Specifically, the sensors are used to sense the rotation position of the replacement cylinder 623, so that the position of the replacement cylinder 623 is accurate and the replacement cylinder 623 is accurately located within the pressing range of the upper pressure cylinder 621 and the lower pressure cylinder 622, so that the water flow is accurate.

[0068] When the switching drive unit 78 is provided, the guide rail can be divided into two parts, namely, into two sections. The upper pressure cylinder 621 slides to the upper section of the sliding rail 72, and the lower pressure cylinder 622 slides to the lower section of the sliding rail 72. There is a gap between the two sections of the sliding rail 72 for connecting the switching drive unit 78, while providing rotation for the switching frame 772 so that the switching frame 772 is not blocked by the sliding rail 72.

[0069] Each water purification cylinder 6 is equipped with a set of switching modules 7, which allows each water purification cylinder 6 to be replaced individually. This avoids situations where the replacement cycles of the pre-filter 21, reverse osmosis membrane 22, and post-activated carbon filter 23 are different, leading to premature or delayed replacement and a reduction in filtration or purification effects.

[0070] In another embodiment, reference Figure 6 As shown, if a single water purifier cylinder 6 is equipped with a set of switching modules 7, it will consume too much power. Therefore, the switching module 7 in this embodiment is different from that in the above embodiment. The switching module 7 itself only needs one set of switching modules 7.

[0071] The switching module 7 in this embodiment is equipped with a connecting frame 776 based on the above embodiment. Specifically, the connecting frame 776 is set between adjacent lifting parts 75 so that when a single lifting part 75 is raised or lowered, the connecting frame 776 can drive multiple lifting parts 75 to rise or fall synchronously, thereby uniformly realizing the lifting and closing of all upper pressure cylinders 621 and all lower pressure cylinders 622.

[0072] However, the switching unit 77 in this embodiment is different from the switching unit 77 described above. In the above embodiment, the changing cylinder 623 is switched out by rotation, while in this embodiment, the switching unit is switched by sliding.

[0073] refer to Figure 6 As shown, the switching unit 77, in addition to the structure of the above embodiment, no longer has the gear 79 and gear ring 774, and additionally adds a switching rail 775. The switching rail 775 is set on the inner wall of the housing or the mounting bracket 1. The switching drive unit 78 adopts a switching cylinder. The switching bracket 772 is slidably connected to the switching rail 775, and all the receiving rings 773 are connected as one unit. The receiving rings 773 still provide the receiving of the replacement cylinder 623. The drive end of the switching cylinder is connected to the switching bracket 772 to provide a pushing effect.

[0074] Specifically, the switching frame 772 connects all the receiving rings 773 into one unit. The replacement cylinder 623 is located inside the receiving ring 773. After the connecting frame 776 and the lifting part 75 separate all the upper pressure cylinders 621 and lower pressure cylinders 622 to both sides, the replacement can be performed. The driving end of the switching drive part 78 pushes the switching frame 772, so that the switching frame 772 drives all the receiving rings 773 and the replacement cylinder 623 to move along the switching rail 775, thereby pushing away the replacement cylinder 623 that was originally located within the pressing range of the upper pressure cylinder 621 and lower pressure cylinder 622, and moving the new replacement cylinder 623 to the pressing range of the upper pressure cylinder 621 and lower pressure cylinder 622, thus completing the replacement.

[0075] Compared to the above embodiments, this method can reduce the requirement for the opening and closing drive unit 71, requiring only one set of opening and closing drive units 71. However, the space inside the housing is limited, making it impossible to install multiple sets of replacement cylinders 623. Therefore, the replacement cylinder 623 can only be replaced once or twice before the entire unit needs to be replaced.

[0076] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
