Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to an intelligent filter cartridge life warning device for water treatment systems. Background Technology

[0002] Water filtration equipment is a specialized device used to purify water. It treats raw water by using built-in filter cartridges or filter media to reduce harmful substances and impurities in the water, making it meet specific usage standards. The filter cartridges in the filtration equipment use their own porous structure to trap visible or tiny solid particles such as silt, rust, suspended solids, and colloids in the water, making the water clearer.

[0003] Ultrapure water has extremely high water quality requirements (resistivity is usually ≥18.2MΩ・cm) and contains almost no impurities. Therefore, ultrapure water uses special filter cartridge structures and materials.

[0004] However, due to the long-term filtration work of the filter element, the filtration quality will gradually decline. In ultrapure water filtration, relying solely on the amount of water filtered to judge the life of the filter element leads to extremely inaccurate judgment of the filter element's life.

[0029] 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.

[0030] Please see Figure 1-4 This utility model provides a technical solution: an intelligent filter cartridge life warning device for a water treatment system, comprising: a protective shell 1, a top cover 101 detachably mounted on the top of the protective shell 1, a base 102 fixedly mounted on the bottom of the protective shell 1, and a warning device 2, which is disposed on the outer side of the bottom of the protective shell 1. The warning device 2 is used to monitor the usage status of the ultrapure water filter cartridge 3. A fixing seat 204 is fixedly mounted on one side of the warning device 2. A resistivity meter 201 and a water pump 202 are fixedly mounted through and fixed on one side of the warning device 2. A detection water chamber 203 is fixedly connected to the input end of the water pump 202. The output of the water pump 202... A purified water outlet pipe is provided at the end. The detection probe of the resistivity meter 201 is inserted through and fixed inside the detection water chamber 203. The ultrapure water filter element 3 is located inside the protective shell 1. An outlet pipe 301 is provided on the outer side of the bottom end of the ultrapure water filter element 3. The outlet pipe 301 is detachably connected to the detection water chamber 203 and is inserted through the protective shell 1. An inlet pipe 302 is provided at the top of the ultrapure water filter element 3. An alarm, a warning light and a touch screen display are provided on one side of the warning device 2. An intelligent control unit is provided inside the warning device 2. The resistivity meter 201 and the outlet pump 202 are both electrically connected to the intelligent control unit.

[0031] After adopting the above technical solution, the filtered water will enter the ultrapure water filter element 3 from the inlet pipe 302. The inlet pipe 302 is connected to a water supply device. The filtered ultrapure water will enter the detection water chamber 203 from the outlet pipe 301. Thus, the detection probe of the resistivity meter 201 can monitor the resistivity of the water passing through at all times, thereby monitoring the filtration quality of the ultrapure water filter element 3. This allows for constant judgment of the service life of the ultrapure water filter element 3. If the resistivity is lower than 18.2 MΩ·cm, the alarm will sound, the warning light will illuminate, and the touch screen display will continuously show the monitored values ​​for easy viewing by staff. This allows for a direct judgment of the filtration quality of the ultrapure water filter element 3. Furthermore, by observing the different resistivities of the ultrapure water filtered each time, the service life of the ultrapure water filter element 3 can be clearly and directly observed. The closer the resistivity monitored by the resistivity meter 201 is to 18.2 MΩ·cm, the shorter the service life of the ultrapure water filter element 3.

[0032] For example, the pressing assembly 4 includes a fixing plate 401, a side bracket 402 symmetrically fixedly disposed on the top of the fixing plate 401, a rotating frame 403 rotatably disposed on the inner side of the top of the side bracket 402, a pressure clamping plate 404 fixedly disposed on the top of the rotating frame 403, a protective clamping pad 405 fixedly disposed on the side of the pressure clamping plates 404 that are close to each other, an ejection spring 408 fixedly disposed in the middle of the top of the fixing plate 401, a pressure guide plate 409 fixedly disposed on the other end of the ejection spring 408, the rotating frame 403 rotatably disposed on the bottom end of the pressure guide plate 409, the protective clamping pad 405 is made of rubber material, torsion springs 407 are fixedly disposed on both sides of the rotating frame 403, a connecting column 406 is fixedly disposed on the other end of the torsion spring 407, the connecting column 406 is fixedly disposed on both sides of the bottom end of the pressure guide plate 409, and a pressure guide column 303 is fixedly disposed in the middle of the bottom end of the ultrapure water filter element 3.

[0033] In an optional embodiment, when the ultrapure water filter element 3 descends into the protective housing 1, the pressure guide column 303 contacts the pressure guide plate 409, causing the pressure guide plate 409 to press down. At this time, the ejector spring 408 will be compressed, and the two rotating frames 403 will be in a closed state, so that the two sets of pressure clamps 404 and protective clamps 405 can form a clamping state on the outside of the pressure guide column 303 and position the pressure guide column 303 so that the pressure guide column 303 is in the center position, thereby positioning and guiding the ultrapure water filter element 3, so that the water outlet pipe 301 can penetrate the protective housing 1. At this time, the torsion spring 407 is also in a contracted state. Thus, after the top cover 101 is removed, due to the stored force of the ejector spring 408 and the torsion spring 407, the ultrapure water filter element 3 can automatically rise, making it easy to take out the ultrapure water filter element 3.

[0034] It should be noted that the two sides of the fixing plate 401 are symmetrically and rotatably provided with a first connecting arm 410, and the other end of the first connecting arm 410 is rotatably provided with a second connecting arm 411, which is rotatably provided on the outside of the pressure guide plate 409.

[0035] In one optional implementation, when the pressure plate 409 is pressed down, the included angle between the first connecting arm 410 and the second connecting arm 411 gradually decreases, and when the pressure plate 409 is raised, the included angle between the first connecting arm 410 and the second connecting arm 411 gradually increases, so that the pressure plate 409 can only move up and down.

[0036] Working principle: Filtered water enters the ultrapure water filter element 3 through the inlet pipe 302. The inlet pipe 302 is connected to a water supply device. The filtered ultrapure water enters the detection water chamber 203 through the outlet pipe 301. The detection probe of the resistivity meter 201 can continuously monitor the resistivity of the water passing through, thereby monitoring the filtration quality of the ultrapure water filter element 3. This allows for continuous assessment of the ultrapure water filter element 3's lifespan. If the resistivity is below 18.2 MΩ·cm, an alarm will sound, a warning light will illuminate, and the touchscreen display will continuously show the monitored values ​​for easy viewing by staff. This provides a direct assessment of the ultrapure water filter element 3's filtration quality. Furthermore, by observing the different resistivities of the ultrapure water filtered each time, the lifespan of the ultrapure water filter element 3 can be clearly observed. The closer the resistivity monitored by the resistivity meter 201 is to 18.2 MΩ·cm, the shorter the lifespan of the ultrapure water filter element 3.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
