Description

Technical Field

[0001] This utility model relates to the field of ultrapure water machine technology, and more specifically, to an ultrapure water machine. Background Technology

[0002] An ultrapure water system is a device used to purify water. It processes raw water such as tap water and well water through multiple steps including pretreatment, reverse osmosis, and ultrapure treatment to remove impurities, dissolved substances, and bacteria, resulting in extremely pure water. An ultrapure water system typically includes a pretreatment system, a reverse osmosis system, and an ultrapure treatment system. Different filtration and treatment processes can achieve different water quality requirements, such as medical ultrapure water and laboratory ultrapure water. Ultrapure water systems are widely used in pharmaceuticals, chemicals, biotechnology, and laboratories, providing high-purity water to meet the needs of various industries.

[0003] When using an ultrapure water machine, the filter cartridge needs to be cleaned or replaced to ensure the filtration effect. When replacing the filter cartridge, the top cover needs to be removed. Most existing top covers are bolted to the top of the main unit. When removing them, multiple bolts need to be unscrewed, which not only requires special tools (screwdriver or Allen wrench) but is also inefficient. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an ultrapure water machine, which aims to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: This utility model provides the following technical solution: an ultrapure water machine, including a main unit and a water tank, wherein the water tank is disposed on one side of the main unit; The top of the water tank is equipped with a water level monitor for water level monitoring, and one side of the water level monitor is equipped with a water tank interface for water diversion. The top of the main unit is equipped with a cover that can be detachably connected to the main unit. A power unit is located at the bottom rear of the cover, corresponding to the top of the main unit. Positioning plates are fixedly connected to both sides of the bottom of the cover. The positioning plates are inserted vertically into the top of the main unit. An insertion rod is fixedly connected to the front end of the positioning plate. The insertion rod is inserted horizontally into the interior of the main unit. A filter cartridge assembly for filtration is located at the bottom of the cover and inside the main unit.

[0006] As can be seen, in the above technical solution, the water tank interface is connected to the water tank mark on the main unit through a hose, the water level monitor is connected to the water level mark on the main unit, and the wastewater mark on the main unit is connected to the floor drain. This makes the device easy to install, and the installation and removal of the top cover and the main unit can be achieved through the power unit, positioning plate, and insertion rod, which is more convenient and faster. Optionally, in possible implementations, the power assembly includes: an elastic element, a guide element, and a moving element; The elastic element is connected to the bottom of the top cover, and the guide element is connected to the moving element. Under the action of the guide element, the moving element moves laterally by utilizing the deformation of the elastic element.

[0007] As can be seen, in the above technical solution, by utilizing the deformation properties of the elastic element, the guide element and the moving element can move laterally at the bottom of the cover. The restoring force of the elastic element can push the cover to move, providing the power for the lateral movement of the cover, which is convenient for installation. When disassembling, simply push the cover backward to compress the elastic element, and the cover can be removed from the main unit.

[0008] Optionally, in a possible implementation, the filter cartridge assembly includes a pretreatment assembly, an RO assembly, a DI resin assembly, and a microfiltration assembly. A touch screen for operation is provided on one side of the main unit surface. The touch screen is detachably connected to the main unit. A three-stage water outlet is provided at the bottom of the touch screen and on the main unit. A two-stage water outlet is provided on one side of the three-stage water outlet and installed on the main unit. Two booster pumps for flow guidance are provided inside the main unit and at the bottom of the filter cartridge assembly. Each booster pump is detachably connected to the main unit. The pretreatment assembly, RO assembly, DI resin assembly, and microfiltration assembly are all threadedly connected to the main unit. As can be seen, in the above technical solution, the raw water enters the main unit and undergoes multi-level coarse filtration through the pretreatment group. Then, it is pumped to the RO group for filtration by the booster pump and then sent to the water tank for storage. The water in the water tank is pumped to the DI resin group for filtration again by the booster pump. Finally, it can be filtered through the microfiltration group, thus realizing the function of multi-level filtration of raw water.

[0009] The main unit is equipped with multiple interfaces, such as a water tank inlet, a water inlet, and a wastewater outlet. The water tank inlet on the main unit is connected to the water tank interface on the water tank through a pipe. The water inlet on the main unit is connected to the indoor delivery pipe, and the wastewater outlet on the main unit is connected to the floor drain through a pipe.

[0010] The technical effects and advantages of this utility model are as follows: The power unit drives the top cover to move, causing the positioning plate and insertion rod inside the upper surface of the main unit to move forward laterally. This allows the insertion rod to insert into the main unit, achieving a limiting effect and connecting the top cover to the main unit. Pushing the top cover backward allows the insertion rod to be removed, and the top cover can then be lifted to separate it from the main unit. This makes disassembly of the top cover from the main unit more convenient and faster. The top cover can be removed to disassemble and maintain the pretreatment group, RO group, DI resin group, and microfiltration group one by one, improving the ease of use of the device.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] As attached Figure 1-6 The ultrapure water machine shown here, through the corresponding cooperation of various structures, allows raw water to enter the main unit 1 and undergo multi-stage coarse filtration through the pretreatment group, then be transported to the RO group for filtration by the booster pump 10, and then be transported to the water tank 2 for storage. The water in the water tank 2 is transported to the DI resin group for filtration again by the booster pump 10, and finally can be filtered through the microfiltration group, thus realizing the function of multi-stage filtration of raw water, and the specific structural settings are as follows; An ultrapure water system includes a main unit 1 and a water tank 2, with the water tank 2 located on one side of the main unit 1; A water level monitor 3 for water level monitoring is installed on the top of the water tank 2, and a water tank interface 4 for water level diversion is installed on one side of the water level monitor 3. The top of the main unit 1 is provided with a top cover 5 that can be detachably connected to the main unit 1. A power assembly 51 is provided at the rear bottom of the top cover 5, corresponding to the top of the main unit 1. Positioning plates 52 are fixedly connected to both sides of the bottom of the top cover 5. The positioning plates 52 are inserted vertically to the top of the main unit 1. An insertion rod 53 is fixedly connected to the front end of the positioning plate 52. The insertion rod 53 is inserted horizontally into the interior of the main unit 1. A filter element group 9 for filtration is provided at the bottom of the top cover 5 and inside the main unit 1.

[0016] The power component 51 drives the upper cover 5 to move, causing the positioning plate 52 and the insertion rod 53, which are inside the upper surface of the main unit 1, to move forward and laterally, so that the insertion rod 53 is inserted into the main unit 1 to achieve a limiting function, thereby connecting the upper cover 5 with the main unit 1. Pushing the upper cover 5 backward in the opposite direction causes the insertion rod 53 to move out, and then the upper cover 5 can be lifted to separate the upper cover 5 from the main unit 1, thus achieving the disassembly of the upper cover 5 from the main unit 1, which is more convenient and faster. It should be noted that the positioning plate 52 is inserted vertically to the top of the main unit 1 and the insertion rod 5353 is inserted horizontally into the interior of the main unit 1. The two insertion positions of the main unit 1 form an L-shaped groove (e.g., Figure 3 As shown), there are four L-shaped slots on the top of the main unit 1, two on each side of the top. The positioning plate 52 is inserted into the vertical section of the L-shaped slot, and the insertion rod 53 is inserted into the horizontal section of the L-shaped slot. The power assembly 51 includes: an elastic element 511, a guide element 512, and a moving element 513; The elastic element 511 is connected to the bottom of the upper cover 5, and the guide element 512 is connected to the moving element 513. Under the action of the guide element 512, the moving element 513 moves laterally by utilizing the deformation of the elastic element 511. By utilizing the deformation property of the elastic element 511, the movable element 513 is pressed against the rear side of the top of the main unit, compressing the elastic element 511. Then, the upper cover 5 is moved down, allowing the positioning plate 52 and the insertion rod 53 to enter the top of the main unit 1. Then, the upper cover 5 is released, and the compressed elastic element 511 returns to its original state, pushing the upper cover 5 forward, allowing the insertion rod 53 to be inserted into the main unit 1 to complete the limiting. This makes installation more convenient. When disassembling, simply push the upper cover 5 backward and then lift the upper cover 5 to separate the upper cover 5 from the main unit 1, making disassembly more efficient. It should be noted that the elastic element 511 can be a spring or other elastic element; the positioning plate 52 is inserted laterally into the bottom of the upper cover 5, and the positioning plate 52 can move laterally at the bottom of the upper cover 5. The elastic element 511 is located inside the upper cover 5, the top of the moving element 513 is located inside the upper cover 5, and the bottom of the moving element 513 is located below the upper cover 5. In actual use, if the movable part 513 is a standard block structure, when installing the top cover 5, the rear end of the movable part 513 needs to be fitted against the upward-protruding front side of the rear top of the main unit 1 (e.g., Figure 3 (The upper left corner is the position where the main unit 1 protrudes upwards). Then, push the upper cover 5 backwards to compress the elastic element 511 until the insertion rod 53 moves directly above the vertical section of the L-shaped groove on the top of the main unit 1. Only then can the upper cover 5 be moved downwards. To reduce the need to move the upper cover 5 backwards during installation and improve installation efficiency, a beveled surface is provided at the rear end of the moving element 513. This way, during installation, the insertion rod 53 can be directly positioned directly above the vertical section of the L-shaped groove on the top of the main unit 1. Press the upper cover 5 downwards directly so that the bottom end of the beveled surface of the moving element 513 first contacts the position where the upper part of the rear top of the main unit 1 protrudes upwards. Continue to press downwards. When the cover 5 moves downwards, the movable part 513 can also move laterally to compress the elastic part 511 under the blocking effect of the beveled surface and the upward protrusion of the top rear side of the main unit 1, until the top of the beveled surface moves to the upward protrusion of the top rear side of the main unit 1. At this time, the elastic part 511 is no longer compressed, and the movable part 513 then only moves downwards and no longer moves laterally. The rear end of the movable part 513 is provided with a beveled surface, so you only need to press the cover 5 downwards, and after reaching the position, release the cover. Under the action of the elastic part 511, the cover 5 can be pushed forward to complete the installation. There are fewer operation steps and higher efficiency. Filter assembly 9 includes a pretreatment group, an RO group, a DI resin group, and a microfiltration group, all of which are interconnected via flexible tubing. The pretreatment group includes a PP filter, a CTO filter, and a PAC filter through which tap water passes in sequence. The RO group includes two RO filter sets. The DI resin group includes six DI resin filter sets. The microfiltration group includes one microfiltration filter set. Filter assembly 9 is a well-known technology in existing ultrapure water systems, and those skilled in the art will not elaborate on its specific mechanisms here. Working principle: A touch screen 6 for operation is provided on one side of the main unit 1. The touch screen 6 is detachably connected to the main unit 1. A three-stage water outlet 7 is provided at the bottom of the touch screen 6 and on the main unit 1. A two-stage water outlet 8 is provided on one side of the three-stage water outlet 7 and installed on the main unit 1. Two booster pumps 10 for guiding flow are provided inside the main unit 1 and at the bottom of the filter group 9. Each booster pump 10 is detachably connected to the main unit 1. The pretreatment group, RO group, DI resin group and microfiltration group are all threadedly connected to the main unit 1.

[0017] The main unit 1 is equipped with multiple interfaces, such as a water tank inlet, a water inlet, and a wastewater outlet. The water tank inlet on the main unit 1 is connected to the water tank interface 4 on the water tank 2 through a pipe. The water inlet on the main unit 1 is connected to the indoor delivery pipe, and the wastewater outlet on the main unit 1 is connected to the floor drain through a pipe.

[0018] According to the above structure, when using the device, the operator will install it in the designated location. During installation, (refer to the appendix) Figure 6 Connect the water tank interface 4 to the water tank label on the main unit 1 via a hose, connect the water level monitor 3 to the water level label on the main unit 1, and connect the wastewater label on the main unit 1 to the floor drain for easy installation. Meanwhile, during the filtration treatment of the raw water, (see attached) Figure 5 Raw water enters the main unit 1 and passes through the pretreatment group, sequentially passing through PP filter, CTO filter and PAC filter for multi-stage coarse filtration. Then it is pumped to the RO group by booster pump 10. After filtration by two sets of RO filter cartridges, the wastewater is directly discharged. The filtered pure water is sent to water tank 2 for storage. At this time, the conductivity of the water is < 5us / cm, which is the third-level water standard. The water in water tank 2 is sent to the DI resin group by another booster pump 10 for filtration again. During this transportation process, it undergoes UV disinfection and sterilization, passes through six sets of DI resin filter cartridges, and finally passes through the microporous filter cartridge of the microfiltration group for filtration. At this time, the resistivity of the water is > 1MΩ·cm @ 25℃, which is the second-level water standard, thus realizing the multi-stage filtration function of raw water. Furthermore, when the device is in use and the filter element group 9 needs to be disassembled and replaced, the top cover 5 can be removed, and the pretreatment group, RO group, DI resin group and microfiltration group can be disassembled and maintained one by one.

[0019] Raw water enters the main unit 1 and undergoes multi-stage coarse filtration through the pretreatment group. Then, it is pumped by the booster pump 10 to the RO group for filtration and then to the water tank 2 for storage. The water in the water tank 2 is pumped by the booster pump 10 to the DI resin group for filtration again. Finally, it can be filtered through the microfiltration group, thus realizing the function of multi-stage filtration of raw water.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
