Description

Technical Field

[0001] This utility model relates to the field of pure water equipment technology, and in particular to a filter component for pure water equipment. Background Technology

[0002] In pure water equipment, reverse osmosis membranes are used to filter and purify water. The reverse osmosis membrane is placed inside a hollow tube. Raw water enters the hollow tube from one end, passes through the reverse osmosis membrane, and the concentrated water exits from the other end. The purified water is discharged through the central product water pipe of the reverse osmosis membrane. Over time, scale buildup can occur on the reverse osmosis membrane, reducing its flux and consequently decreasing its filtration efficiency, necessitating timely replacement. Currently, methods such as calculating the membrane's lifespan or removing it from the hollow tube to observe the degree of scaling are insufficient for timely detection of scaling. This can lead to premature or delayed membrane replacement, affecting water filtration and purification efficiency and failing to meet the requirements of pure water equipment. Utility Model Content

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] like Figure 1-8The image shows a filtration assembly for a pure water device according to this embodiment. This filtration assembly is used in a pure water device to filter and purify water. The filtration assembly includes a housing 1, end components 2, and a display screen. The housing 1 has a hollow structure with open ends. The end components 2 are arranged at both ends of the housing 1 to seal the open ends. A reverse osmosis membrane assembly is installed inside the housing 1 in the same direction. This reverse osmosis membrane assembly is a conventional component in the prior art, and its structure is also conventional. The reverse osmosis membrane assembly is used to filter and purify water. Specifically, the reverse osmosis membrane assembly includes a product water pipe 6 and a reverse osmosis membrane 61 arranged around the periphery of the product water pipe 6. Product water holes are distributed on the product water pipe 6. The pure water filtered by the reverse osmosis membrane 61 enters the product water pipe 6 through the product water holes. In this embodiment, the working principle of the above-mentioned reverse osmosis membrane assembly is common knowledge.

[0031] The aforementioned end assembly 2 includes a cap seat 21 and a monitoring camera 5. The cap seat 21 extends into the interior of the housing 1 and caps the open end of the housing 1. A glass tube 3 is mounted on the cap seat 21 surrounding the outer side of the end of the reverse osmosis membrane 61. Both ends of the glass tube 3 are sealed to the cap seat 21. An interlayer space 31 is formed on the cap seat 21 outside the glass tube 3. Specifically, the cap seat 21 includes a seat body and a cap body 22. The seat body has a bottom wall 211 and an annular sidewall 212 formed on the bottom wall 211. The annular sidewall 212 is inserted into the open end of the housing 1 and is threadedly connected to the inner peripheral wall of the housing 1 to seal the open end of the housing 1. A first annular slot 213 is machined on the bottom wall 211 inside the annular sidewall 212. An insertion channel is formed on the bottom wall 211 inside the first annular slot 213. During assembly, the end of the reverse osmosis membrane 61 is inserted into the insertion channel. The cover 22 is detachably bolted to the top of the annular sidewall 212. A second annular slot 221 is machined onto the cover 22 corresponding to the first annular slot 213. The aforementioned glass tube 3 is arranged between the bottom wall 211 and the cover 22. One end of the glass tube 3 is sealed and inserted into the first annular slot 213, and the second end is sealed and inserted into the second annular slot 221 to achieve a sealed assembly of the glass tube 3. The aforementioned interlayer space 31 is formed between the glass tube 3 and the annular sidewall 212. To achieve a better sealing fit, rubber seals can be fitted to both ends of the glass tube 3, which are then inserted into the first annular slot 213 and the second annular slot 221, respectively. Through the above structural design, the glass tube 3 surrounds the periphery of the reverse osmosis membrane 61, isolating the interlayer space 31 from the interior of the shell 1 to prevent water from entering the interlayer space 31.

[0032] In this embodiment, at least one set of monitoring cameras 5 are installed in the interlayer space 31, each having a monitoring end facing the glass tube 3. The number of monitoring cameras 5 is determined according to actual needs, and they are arranged at intervals in the interlayer space 31. Through the above structural design, the monitoring ends of the monitoring cameras 5 can acquire the scaling condition on the surface of the reverse osmosis membrane 61 in real time and output image information. The display screen is arranged outside the housing 1, and can be arranged in the central control room. The display screen is connected to the monitoring cameras 5 via wired or wireless means, and is used to display the images acquired by the monitoring cameras 5 in real time. When the display screen is wired to the monitoring cameras 5, the cable passes through the cover 22 to the outside.

[0033] In this embodiment, a control circuit board 7 and a power supply can be installed in the interlayer space 31 according to actual needs. The operation of the monitoring camera 5 can be controlled by the control circuit board 7. A socket 44 is machined on the cover 22. The control circuit board 7 and the power supply are inserted into the interlayer space 31 through the socket 44, and the socket 44 is sealed by a sealing plate.

[0034] In this embodiment, the cover 22 of the first-side cap seat 21 is machined with a water inlet 4 and a sealing position 45. The aforementioned water inlet 4 is connected to the housing 1 so that raw water enters the housing 1 through the water inlet 4. During assembly, the sealing position 45 is closedly connected to the first end of the water production pipe 6 to seal the first end of the water production pipe 6, thereby preventing pure water from being discharged from that end of the water production pipe 6. The cover 22 of the aforementioned second-side cap seat 21 is machined with a pure water outlet 41 and a concentrated water outlet 42. The pure water outlet 41 is connected to the second end of the water production pipe 6, and the pure water inside the water production pipe 6 is discharged through the pure water outlet 41. The aforementioned concentrated water outlet 42 is connected to the housing 1, and the filtered concentrated water is discharged through the concentrated water outlet 42.

[0035] The aforementioned end assembly 2 includes a bracket 51. Several of the aforementioned monitoring cameras 5 are fixedly mounted to the bracket 51 by bolts. The aforementioned cover 22 has an assembly port 43 that communicates with the interlayer space 31. The size of the assembly port 43 is adapted to the size of the monitoring camera 5, allowing the monitoring camera 5 to freely pass through the bracket 51 and engage with the cover 22, and it has an assembled state with the assembly port 43 closed. In this assembled state, the bracket 51 is fixed to the cover 22 by bolts, and the monitoring camera 5 is inserted into the interlayer space 31 via the assembly port 43. By disassembling the bracket 51, each monitoring camera 5 can be removed from the interlayer space 31. In the assembled state, the bracket 51 closes the assembly port 43 to prevent dust and other impurities from entering the interlayer space 31.

[0036] In this embodiment, in the aforementioned end components 2 on both sides, the cover 22 of the first-side cap seat 21 has a positioning boss 46 machined around the sealing position 45, and the cover 22 of the second-side cap seat 21 has a positioning boss 46 machined around the pure water outlet 41. Positioning bosses 46 have positioning holes. During assembly, both ends of the water production pipe 6 are respectively inserted into the corresponding positioning holes to position and fix the water production pipe 6. The first end of the water production pipe 6 is sealed by the sealing position 45 on the cover 22, and the second end is connected to the pure water outlet 41.

[0037] During assembly, open the covers 22 of the sealing seats 21 on both sides to insert the monitoring camera 5 into the interlayer space 31, and then close the covers 22 to close the interlayer space 31. The monitoring camera 5 is positioned in the interlayer space 31 to isolate it from the water, preventing damage during use. The monitoring camera 5 acquires images of the reverse osmosis membrane 61 and displays them on the screen, allowing for real-time monitoring of the scaling level on the reverse osmosis membrane 61. This enables timely replacement of the reverse osmosis membrane 61, effectively meeting the needs of pure water equipment and demonstrating strong practicality.
