Description

Technical Field

[0001] This utility model relates to the field of ultrapure water machines, and in particular to an ultrapure water machine that is easy to clean. Background Technology

[0002] An ultrapure water system is a specialized device that uses multiple precision purification technologies to deeply treat raw water to remove various impurities and produce ultrapure water.

[0003] Ultrapure water systems typically integrate a pretreatment system to remove large particulate impurities and residual chlorine, a reverse osmosis system to retain ions and organic matter, an ion exchange system to further reduce ion concentration, and an ultraviolet sterilization or microfiltration system to ensure sterile and particulate-free water. They are widely used in fields with extremely high water quality requirements, such as laboratory analysis and testing, electronic semiconductor manufacturing, biomedical research and development, and precision electroplating. The water produced must meet relevant international or industry standards.

[0004] Ultrapure water systems commonly suffer from cumbersome disassembly and assembly of their outer casings, often requiring additional tools and the removal of multiple sets of screws or complex clips, resulting in numerous and time-consuming steps. This directly hinders users from quickly and easily opening the casing, thus preventing full exposure of the internal space. Deep components such as the inner walls, outlet pipes, and base remain untouched by cleaning, easily accumulating dirt, impurities, or residues. With increased usage, these uncleaned areas not only affect the overall cleanliness of the equipment but may also reduce operating efficiency and even shorten its lifespan due to blockages and corrosion caused by dirt. This fails to meet users' needs for convenient maintenance and thorough cleaning. Therefore, a more easily cleanable ultrapure water system is proposed to address these issues. Utility Model Content

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an easy-to-clean ultrapure water machine, comprising a fixed outer shell, an internal disassembly and sealing mechanism inside the fixed outer shell, and an external disassembly mechanism outside the fixed outer shell. The internal disassembly and sealing mechanism includes a base, which is detachably connected to the inner wall of the fixed outer shell via a stud. A lower fixed cylinder is fixedly connected to the top of the base, a water outlet pipe is fixedly connected to the outer wall of the lower fixed cylinder, and a lower fixed shell is fixedly connected to the outer wall of the water outlet pipe. A lower fixed block is inserted into the inner wall of the lower fixed shell, and an upper fixed block is detachably connected to the inner wall of the lower fixed block via a stud. An upper fixed shell is fixedly connected to the side wall of the upper fixed block, and a movable block is threadedly connected to the inner wall of the lower fixed block via a stud. A sealing ring is fixedly connected to the bottom end of the movable block, and the outer wall of the sealing ring is inserted into the inner wall of the lower fixed shell. An upper fixed cylinder is fixedly connected to the inner wall of the upper fixed shell.

[0007] Preferably, the internal disassembly and sealing mechanism further includes a pull rod, the outer wall of which is slidably connected to the inner wall of the lower fixed shell, and the inner wall of the lower fixed shell is elastically connected to a wedge block by a spring, the outer wall of which is inserted into the inner wall of the lower fixed block.

[0008] Preferably, the outer wall of the sealing ring is slidably connected to the inner wall of the upper fixed shell, the outer wall of the moving block is slidably connected to the inner wall of the upper fixed shell, and the outer wall of the water outlet pipe is fixedly connected to the inner wall of the fixed shell.

[0009] Preferably, one end of the spring is fixedly connected to the inner wall of the lower fixed shell, and the other end of the spring is fixedly connected to the bottom end of the wedge.

[0010] Preferably, the external disassembly mechanism includes a support block, a fixed outer shell is fixedly connected to the top of the support block, a rotating cylinder is rotatably connected to the inner wall of the support block, a moving rod is slidably connected to the inner wall of the rotating cylinder, and a paddle is elastically connected to the inner wall of the rotating cylinder by a spring, and the side wall of the paddle is fixedly connected to the side wall of the moving rod.

[0011] Preferably, the outer wall of the movable rod is slidably connected to the inner wall of the support block, and the outer wall of the movable rod is inserted into the inner wall of the fixed housing.

[0013] Preferably, the external disassembly mechanism further includes a handle, the outer wall of which is fixedly connected to the outer wall of the fixed housing.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the internal disassembly and sealing mechanism connects the base and the fixed outer shell through studs, providing stable support for components such as the lower fixed cylinder and water outlet pipe. It also utilizes a spring-driven wedge block to engage with the studs, achieving positioning and sealing of the upper and lower fixed blocks, preventing ultrapure water leakage and maintaining water purity. Pulling the lever and unscrewing the studs allows for the separation of components, facilitating cleaning and replacement.

[0016] 2.

Detailed Implementation

[0023] 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.

[0024] Reference Figures 1-3This utility model provides an embodiment of an easy-to-clean ultrapure water machine, including a fixed outer shell 1. An internal disassembly and sealing mechanism 2 is provided inside the fixed outer shell 1, and an external disassembly mechanism 3 is provided outside the fixed outer shell 1. The internal disassembly and sealing mechanism 2 includes a base 212, which is detachably connected to the fixed outer shell 1 via studs 221. This base 212 provides stable support for components such as the lower fixed cylinder 213 and the water outlet pipe 214, ensuring the water flow channel and core components are securely installed. After disassembly, the base 212 and related components can be cleaned separately, preventing impurities from remaining at the bottom. The base 212 is detachably connected to the inner wall of the fixed outer shell 1 via studs 221, which connect the base 212 to the fixed outer shell 1, the lower fixed block 218 to the movable... The movable block 223 serves both fixing and adjustment functions. When fixed, it ensures a stable connection between components. When adjusted, it can be pushed to drive the sealing ring 224 to achieve sealing or reset. A lower fixed cylinder 213 is fixedly connected to the top of the base 212. The lower fixed cylinder 213 is fixed to the top of the base 212 and serves as one of the core water treatment carriers for ultrapure water preparation. It works with the upper fixed cylinder 215 to form a complete water treatment process. The detachable design allows for easy removal for cleaning or replacement of filter media, ensuring water treatment efficiency and water purity. A water outlet pipe 214 is fixedly connected to the outer wall of the lower fixed cylinder 213. The water outlet pipe 214 is fixed to the outer wall of the lower fixed cylinder 213 and connected to the fixed outer shell 1, forming an ultrapure water output channel to ensure stable delivery of treated ultrapure water. It can be disassembled synchronously with the core components. This system can clean residual scale or impurities inside the pipe, preventing pipe blockage and affecting water output. A lower fixing shell 216 is fixedly connected to the outer wall of the outlet pipe 214. The lower fixing shell 216 is fixed to the outer wall of the outlet pipe 214, providing insertion space for the lower fixing block 218. It also supports positioning components such as the wedge block 222 and spring 226. Through cooperation with the lower fixing block 218, it achieves initial positioning of the core component. The lower fixing block 218 is inserted into the inner wall of the lower fixing shell 216. The lower fixing block 218 is inserted into the inner wall of the lower fixing shell 216 and, through positioning by the wedge block 222, connects to the upper fixing block 219 via the stud 220, serving as the connection hub for the core component. After disassembly, it can simultaneously separate the upper fixing block 219 and related components, simplifying the disassembly process. The inner wall of the lower fixing block 218 is connected by the stud 220. The upper fixing block 219 is detachably connected to the lower fixing block 218 via a stud 220. Unscrewing the stud allows for quick separation of the upper and lower fixing structures, providing operational space for disassembling and cleaning the core components. This is a key fastener for disassembling the internal structure. The upper fixing block 219 is fixed to the side wall of the upper fixing shell 217 and connected to the lower fixing block 218 via the stud 220, causing the upper fixing shell 217 to mate with the lower fixing shell 216. It also provides installation support for the moving block 223 and the sealing ring 224. The upper fixing block 219 is fixedly connected to the side wall of the upper fixing shell 217. The upper fixing shell 217 and the lower fixing shell 216 mate to form a closed water treatment space, providing installation and movement space for the upper fixing cylinder 215, the moving block 223, and the sealing ring 224.The sliding trajectory of the sealing ring 224 is limited to ensure precise insertion into the lower fixed shell 216 during sealing, thus guaranteeing the sealing effect. A movable block 223 is threadedly connected to the inner wall of the lower fixed block 218 via a stud 221. The movable block 223 is connected to the lower fixed block 218 via the stud 221 and slides along the inner wall of the upper fixed shell 217 as the stud 221 rotates, pushing the sealing ring 224 to achieve sealing or reset. The sealing ring 224 is fixedly connected to the bottom end of the movable block 223, and the sealing ring 224 is fixed to the bottom end of the movable block 223, inserting as the movable block 223... The inner wall of the lower fixed shell 216 fits snugly against the upper fixed shell 217, filling the gaps between components to achieve a water flow seal, preventing ultrapure water leakage or the entry of external impurities. The outer wall of the sealing ring 224 is inserted into the inner wall of the lower fixed shell 216. An upper fixed cylinder 215 is fixedly connected to the inner wall of the upper fixed shell 217. The upper fixed cylinder 215 is fixed to the inner wall of the upper fixed shell 217 and works with the lower fixed cylinder 213 to complete the ultrapure water preparation process, such as filtration and adsorption. The detachable design facilitates regular cleaning or replacement of the internal filter media, maintaining water treatment performance and preventing filter media saturation from affecting water quality.

[0025] Reference Figures 1-3 The internal disassembly and sealing mechanism 2 also includes a pull rod 225, which is pulled by the operator to drive the wedge block 222 to compress the spring 226 and disengage from the lower fixing block 218, thus releasing the insertion and positioning of the lower fixing block 218 and the lower fixing shell 216. The outer wall of the pull rod 225 is slidably connected to the inner wall of the lower fixing shell 216. The wedge block 222 is elastically connected to the inner wall of the lower fixing shell 216 through the spring 226. Under the elastic force of the spring 226, the wedge block 222 is inserted into the inner wall of the lower fixing block 218, locking the relative position of the lower fixing block 218 and the lower fixing shell 216 to prevent the parts from shifting after docking. Pulling the pull rod 225 disengages the wedge block 225, releasing the lock, and the spring 226... 6 connects the lower fixed shell 216 and the wedge 222, providing elastic thrust to keep the wedge 222 always inserted into the lower fixed block 218, ensuring reliable positioning in non-operational state. When the pull rod 225 is pulled, it is compressed, allowing the wedge 222 to move. The outer wall of the wedge 222 is inserted into the inner wall of the lower fixed block 218. The outer wall of the sealing ring 224 is slidably connected to the inner wall of the upper fixed shell 217. The outer wall of the moving block 223 is slidably connected to the inner wall of the upper fixed shell 217. The outer wall of the water outlet pipe 214 is fixedly connected to the inner wall of the fixed shell 1. One end of the spring 226 is fixedly connected to the inner wall of the lower fixed shell 216, and the other end of the spring 226 is fixedly connected to the bottom end of the wedge 222.

[0026] Reference Figure 4The external disassembly mechanism 3 includes a support block 311. A second fixed outer shell 211 is fixed to the top of the support block 311, providing basic support for the external support structure. It is also connected to the first fixed outer shell 1 via a moving rod 313, ensuring the overall stability of the equipment structure and supporting components such as the rotating cylinder 312 and the second spring 315. The second fixed outer shell 211 is fixedly connected to the top of the support block 311, forming an external protective and support frame for the equipment, protecting the internal mechanisms from collisions. It also provides an installation position for the handle 316, facilitating the operator's gripping and separation of the outer shell. A rotating cylinder 312 is rotatably connected to the inner wall of the support block 311. The rotating cylinder 312 is fixed to the inner wall of the support block 311, providing installation and sliding space for the moving rod 313, spring 315, and lever 314, limiting the movement trajectory of the moving rod 313, and ensuring that the moving rod 313 can accurately insert into or detach from the fixed outer shell 1. The moving rod 313 is slidably connected to the inner wall of the rotating cylinder 312. Under the elastic force of spring 315, the moving rod 313 inserts into the inner wall of the fixed outer shell 1, locking the connection between the fixed outer shell 1 and the external support structure. When the lever 314 is pressed, it disengages, releasing the connection. The inner wall of the rotating cylinder 312 is elastically connected by spring 315. A lever 314 is connected, which is pressed by the operator to drive the moving rod 313 to compress the second spring 315 and disengage it from the fixed housing 1, thus detaching the external structural connection. After being released, it returns to its original position under the action of the second spring 315, simplifying the housing separation process. The second spring 315 connects the rotating cylinder 312 and the lever 314, providing elastic thrust to keep the moving rod 313 inserted into the fixed housing 1, ensuring a stable external structural connection when not in operation. When the lever 314 is pressed, it is compressed, allowing the moving rod 313 to move. The side wall of the lever 314 is fixedly connected to the side wall of the moving rod 313, and the outer wall of the moving rod 313... The moving rod 313 is slidably connected to the inner wall of the support block 311, and the outer wall of the moving rod 313 is inserted into the inner wall of the fixed outer shell 1. One end of the spring 315 is fixedly connected to the inner wall of the fixed outer shell 1, and the other end of the spring 315 is fixedly connected to the side wall of the lever 314. The external disassembly mechanism 3 also includes a handle 316, which is fixed to the outer wall of the fixed outer shell 211 for the operator to hold. This facilitates the pulling of the fixed outer shell 211 after the external structure is unlocked, thereby separating the fixed outer shell 1 from the external support structure, improving the ease of operation, and preventing hand slippage during separation. The outer wall of the handle 316 is fixedly connected to the outer wall of the fixed outer shell 211.

[0027] Working principle: The base 212 is detachably connected to the inner wall of the fixed outer shell 1 via stud 221, providing stable support for components such as the lower fixed cylinder 213 and the water outlet pipe 214. The water outlet pipe 214 is fixed to the outer wall of the lower fixed cylinder 213 and connected to the inner wall of the fixed outer shell 1, ensuring a stable water flow channel. The lower fixed block 218 is inserted into the inner wall of the lower fixed shell 216, and the wedge 222 automatically inserts into the lower fixed block 218 under the elastic force of the spring 226, completing the initial positioning. Column 220 connects the upper fixing block 219 and the lower fixing block 218, aligning the upper fixing shell 217 and the lower fixing shell 216. Rotating the stud 221 on the inner wall of the lower fixing block 218 pushes the moving block 223 to slide along the inner wall of the upper fixing shell 217. The moving block 223 causes the sealing ring 224 to insert into the inner wall of the lower fixing shell 216. Simultaneously, the sealing ring 224 tightly adheres to the inner wall of the upper fixing shell 217, achieving a seal, preventing ultrapure water leakage, and ensuring water purity. Pulling the lever 225... Drive the wedge block 222 to compress the spring 226 and disengage it from the lower fixed block 218, releasing the insertion limit between the lower fixed block 218 and the lower fixed shell 216. Unscrew the stud 220 to separate the upper fixed block 219 from the lower fixed block 218, causing the upper fixed shell 217 to separate from the lower fixed shell 216. Rotate the stud 221 in the opposite direction, and the moving block 223 will drive the sealing ring 224 to reset, releasing the sealing state and removing the core components. At this time, the core water treatment components such as the upper fixed cylinder 215 and the lower fixed cylinder 213 can be removed for cleaning and replacement. The operation is convenient and avoids the accumulation of impurities affecting the quality of ultrapure water. The top of the support block 311 is fixedly connected to the fixed shell 211, forming the external support structure of the equipment. Under the elastic force of the spring 215, the moving rod 313 is pushed into the inner wall of the fixed shell 1 by the paddle 314. At the same time, the moving rod 313 slides with the inner wall of the support block 311, firmly connecting the fixed shell 1 and the fixed shell 211, ensuring the overall stability of the equipment structure.

[0028] Pressing the lever 314 compresses the second spring 315, causing the moving rod 313 to slide along the inner wall of the rotating cylinder 312. This disengages the moving rod 313 from the inner wall of the fixed outer shell 1, releasing the connection between the fixed outer shell 1 and the external support structure, thus separating the outer shell from the deep cleaning area. Holding the handle 316 allows separation of the fixed outer shell 1 from the fixed outer shell 211, support block 311, and other external structures, exposing the overall internal space of the equipment. At this point, not only can the inner wall of the fixed outer shell 1 be cleaned, but also deep components such as the water outlet pipe 214 and the base 212 can be thoroughly cleaned, further ensuring the cleanliness of the equipment. After cleaning, align the fixed outer shell 1 with the support block 311, release the lever 314, and the moving rod 313 will automatically insert into the inner wall of the fixed outer shell 1 under the action of the second spring 315, completing the shell reset and fixation.
