[0002] University laboratories, hospitals, and research institutes have high requirements for water quality and usually use pure water systems to produce pure water. The filter element is an important part of the filtration process in the pure water system.

[0003] Modern filter cartridges are often complicated to install, and once installed, they cannot be replaced or are inconvenient to replace quickly, requiring them to be returned to the manufacturer for replacement, which wastes time and money. Utility Model Content

[0004] To facilitate replacement and disassembly, this application provides a modular quick-release filter cartridge housing for laboratory pure water systems.

[0005] The modular quick-release filter cartridge housing for a laboratory pure water system provided in this application adopts the following technical solution:

[0006] A modular quick-release filter cartridge housing for a laboratory pure water system includes a housing for installing the filter cartridge. The housing has an end cap at its upper end and a base at its lower end. The end cap has a quick-connect socket, which is connected to the pure water system by bolts. The quick-connect socket includes two opposing ribs with horizontal quick slots on their opposing sides. The bottom of the end cap has an outwardly extending horizontal edge, which includes quick-insertion edges on both sides of the end cap that correspond one-to-one with the quick slots. A snap-on cover for engaging with the upper surface of the end cap is rotatably connected to the quick-connect socket. The side of the end cap facing away from the quick-connect socket has an inclined engaging surface with a recessed groove. The snap-on cover has a locking block that engages with the groove.

[0007] By adopting the above technical solution, the operator installs the quick-connect socket into the water purifier using bolts, flips up the cover to open the quick-connect socket, and then installs the housing with the filter element. At this point, the quick-connect edge is aligned with the quick-connect slot, and the housing is pushed horizontally to connect it to the quick-connect socket. The operator then flips down the cover, which presses against the end cover, and the locking block engages in the slot, thus completing the housing installation. Removal is simple; just slide the housing along the quick-connect slot. This method is convenient for installation and replacement.

[0008] Preferably, the horizontal edge also includes an arcuate edge located between the two quick-connect edges, the arcuate edge being located on the side of the horizontal edge facing the quick-connect socket.

[0009] By adopting the above technical solution, the arc-shaped edge facilitates the insertion of the housing.

[0010] Preferably, a mounting plate is vertically connected between the two ribs. The mounting plate is located on the side of the rib away from the end cover. The mounting plate is connected to the pure water instrument by bolts. A water receiving plate is detachably connected to the mounting plate. The water receiving plate is provided with several water receiving pipes for connecting the end cover and the pure water instrument. The end cover is provided with connecting pipes that correspond one-to-one with the water receiving pipes.

[0011] By adopting the above technical solution, the housing is installed on the quick-connect socket, and the connecting pipe is connected to the water inlet pipe. The water in the pure water instrument circulates in the housing through the water inlet pipe and the connecting pipe, thereby being filtered through the filter element to improve the water quality.

[0012] Preferably, the water receiving plate is provided with two or three water receiving pipes.

[0013] By adopting the above technical solutions, two types of water receiving plates, two-way and three-way water receiving plates, meet the usage requirements of different pure water instruments.

[0014] Preferably, the end of the water inlet pipe facing the connecting pipe has at least two sealing grooves, and a sealing ring is installed in the sealing groove.

[0015] By adopting the above technical solution, multiple sealing rings are used to seal the connection between the water pipe and the connecting pipe, thereby improving the sealing effect.

[0016] Preferably, the end of the connecting pipe facing the water inlet pipe is provided with an annular inclined pressure ring groove. The outer diameter of the inclined pressure ring groove is greater than or not less than the outer diameter of the sealing ring. The outer circle of the inclined pressure ring groove is located at the end of the connecting pipe near the water inlet pipe. The inner wall of the inclined pressure ring groove is inclined.

[0017] By adopting the above technical solution, during the process of inserting the water pipe into the connecting pipe, the sealing ring contacts the inclined pressure ring groove. The inclined pressure ring groove on the inner wall squeezes the upper end of the sealing ring. As the shell and connecting pipe move continuously, the sealing ring is gradually pressed into the connecting pipe, reducing the resistance brought by the sealing ring, making the use smoother and easier to install.

[0018] Preferably, the water inlet pipe includes an inlet pipe and several outlet pipes, the connecting pipe includes a filter pipe connected to the inlet pipe and a drain pipe connected to the outlet pipes, the housing is provided with a clean water chamber and an outlet water chamber, the filter element is installed in the clean water chamber, the clean water chamber is connected to the filter pipe, and the drain pipe is connected to the outlet water chamber.

[0019] Preferably, the base is provided with a water purification tank connected to the water purification chamber and a drainage tank connected to the water outlet chamber, and the base is provided with a water outlet tank for connecting the water purification tank and the drainage tank.

[0020] By adopting the above technical solution, the water in the pure water instrument enters the water purification chamber through the inlet pipe, and after being filtered by the filter element, it flows back into the pure water instrument from the outlet chamber.

[0021] Preferably, a support cylinder is detachably connected to the upper part of the housing. The outer wall of the support cylinder is provided with a support ring that abuts against the inner wall of the housing. A connecting cylinder is provided at the upper end of the support cylinder. A plug-in cylinder is provided on the lower surface of the end cap, which is directly opposite to and connected to the connecting cylinder.

The connecting cylinder is inserted into the plug-in gap. Multiple rubber rings are provided on the outer wall of the connecting cylinder.

[0022] By adopting the above technical solution, filter elements of various diameters are used. Larger diameter filter elements are directly installed inside the housing for filtration. For smaller diameter filter elements, they are first installed in the support cylinder, and then the smaller diameter filter element is installed into the housing along with the support cylinder. A connecting cylinder is inserted into the insertion gap, and a rubber ring seals the connecting cylinder. At this time, the support ring abuts against the inner wall of the housing, thereby improving the stability of the smaller diameter filter element during installation.

[0023] Preferably, the end cap has vertical lugs on both sides of its upper surface.

[0024] By adopting the above technical solution, the housing can be directly installed in parallel in the rack system, which facilitates the miniaturization, batch replacement or maintenance design of the equipment.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting two sealing rings, dual protection of dynamic and static sealing is achieved, which significantly improves the system's sealing life and pressure resistance.

[0038] Example

[0039] This application discloses a modular quick-release filter cartridge housing for a laboratory pure water system, referring to... Figure 1 and Figure 2 It includes a quick-connect socket 4 and a housing 1. An end cap 2 is provided on the top of the housing 1, and a base 3 is provided on the bottom of the housing 1.

[0040] Reference Figure 1 and Figure 2 The housing 1 has a water purification chamber 11 and a water outlet chamber 12, which are independently configured. A filter element is installed in the water purification chamber 11. Water enters the water purification chamber 11, is filtered by the filter element, and is discharged from the water outlet chamber 12.

[0041] Reference Figure 2 and Figure 3 The base 3 is equipped with a water purification tank 31 connected to the water purification chamber 11 and a drain trough 32 connected to the water outlet chamber 12. The base 3 also has an outlet trough 33 for connecting the water purification tank 31 and the drain trough 32. Water enters from the top of the water purification chamber 11, is filtered by the filter element, flows into the drain trough 32 of the base 3, then flows into the water outlet chamber 12 through the outlet trough 33, and finally flows out and back into the pure water instrument.

[0042] Reference Figure 1 and Figure 4 The end cap 2 is installed on the top of the housing 1 to connect the quick-connect socket 4 and the housing 1. The quick-connect socket 4 includes two opposing ribs 41 and a mounting plate 42 vertically connected between the two ribs 41. The mounting plate 42 is located on the side of the ribs 41 away from the end cap 2, and has four bolt holes for connection to the pure water instrument via bolts.

[0043] Reference Figure 1 and Figure 4 The mounting plate 42 has a mounting hole in its center, and a water receiving plate 5 is detachably connected to the mounting hole. The water receiving plate 5 is connected to the mounting hole by means of snap-fit ​​or other methods. The water receiving plate 5 is provided with several water receiving pipes 51 for connecting the end cap 2 and the pure water instrument. The end cap 2 is provided with connecting pipes 22 that correspond one-to-one with the water receiving pipes 51.

[0044] Reference Figure 4 and Figure 5 The water receiving plate 5 comes in two models: one with two water receiving pipes 51 and the other with three water receiving pipes 51. These two models are designed to match different models of pure water analyzers. The water receiving plate 5 is detachably connected to the mounting plate 42, making disassembly and assembly convenient and easy to replace. Similarly, the end cap 2 corresponding to the water receiving plate 5 also comes in two models: one with two connecting pipes 22 and the other with three connecting pipes 22.

[0045] Reference Figure 4 The end of the water inlet pipe 51 facing the connecting pipe 22 has at least two sealing grooves 511, and a sealing ring 52 is installed in the sealing groove 511. The multiple sealing rings 52 seal the connection between the water inlet pipe 51 and the connecting pipe 22, thereby improving the sealing effect.

[0046] Reference Figure 4 The connecting pipe 22 has an annular inclined groove 221 at its end facing the water inlet pipe 51. The outer diameter of the inclined groove 221 is greater than or equal to the outer diameter of the sealing ring 52. The outer groove 221 is located at the end of the connecting pipe 22 closest to the water inlet pipe 51, and the outer and inner rings of the inclined groove 221 are inclined together. During the insertion of the water inlet pipe 51 into the connecting pipe 22, the sealing ring 52 contacts the inclined groove 221. The inclined groove 221 on the inner wall squeezes the upper end of the sealing ring 52. As the housing 1 and the connecting pipe 22 move continuously, the sealing ring 52 is gradually pressed into the connecting pipe 22, reducing the resistance brought by the sealing ring 52, making it easier to use and install.

[0047] Reference Figure 3 and Figure 4The water inlet pipe 51 includes an inlet pipe 512 and several outlet pipes 513. The connecting pipe 22 includes a filter pipe 222 connected to the inlet pipe 512 and a drain pipe 223 connected to the outlet pipes 513. The purified water chamber 11 is connected to the filter pipe 222, and the drain pipe 223 is connected to the outlet chamber 12. Water in the pure water device enters the purified water chamber 11 through the inlet pipe 512 for filtration, and the filtered water flows back into the pure water device through the outlet pipes 513.

[0048] Reference Figure 3 The upper part of the housing 1 is detachably connected to a support cylinder 6 located in the water purification chamber 11. The outer wall of the support cylinder 6 is provided with a support ring 61 that abuts against the inner wall of the housing 1. The upper end of the support cylinder 6 is provided with a connecting cylinder 62, and the outer wall of the connecting cylinder 62 is provided with multiple rubber rings 63.

[0049] Reference Figure 3 and Figure 6 The lower surface of the end cap 2 is provided with a plug-in cylinder 24 that is directly opposite to and connected to the connecting cylinder 62. The inner ring of the plug-in cylinder 24 is provided with a water guide pipe 25 that is connected to the filter pipe 222. An annular plug-in gap 26 is formed between the plug-in cylinder 24 and the water guide pipe 25. The connecting cylinder 62 is inserted into the plug-in gap 26.

[0050] Reference Figure 3 and Figure 6 The filter elements come in various diameters. Larger diameter filter elements are directly installed inside the housing 1 for filtration. Smaller diameter filter elements are first installed in the support cylinder 6, and then installed into the housing 1 along with the support cylinder 6. The connecting cylinder 62 is inserted into the insertion gap 26, and a rubber ring 63 seals the connecting cylinder 62. At this time, the support ring 61 abuts against the inner wall of the housing 1, thereby improving the stability of the smaller diameter filter element during installation.

[0051] Reference Figure 4 The ribs 41 have horizontal quick slots 411 on their opposite sides. The bottom of the end cover 2 has an outwardly extending horizontal edge 21, which includes quick insertion edges 211 on both sides of the end cover 2 that correspond one-to-one with the quick slots 411. The horizontal edge 21 also includes an arcuate edge 212 located between the two quick insertion edges 211, which is located on the side of the horizontal edge 21 facing the quick socket 4.

[0052] Reference Figure 1 and Figure 4 The operator installs the quick-connect socket 4 into the water purifier using bolts, and then installs the housing 1 with the filter element. At this point, the quick-connect edge 211 is aligned with the quick-connect slot 411, and the arc edge 212 faces the mounting plate 42. The housing 1 is then pushed horizontally to connect it to the quick-connect socket 4, thus completing the installation of the housing 1. To remove it, simply slide the housing 1 along the quick-connect slot 411. The installation and removal are convenient and easy to replace.

[0053] Reference Figure 4 The quick-connect socket 4 is rotatably connected to a snap-on cover 43 for engaging the upper surface of the end cover 2. The two sides of the snap-on cover 43 near the end of the mounting plate 42 are rotatably connected to two ribs 41 respectively. The lower surface of the snap-on cover 43 is provided with a recessed snap-on groove 431 that matches the upper surface of the end cover 2.

[0054] Reference Figure 4 and Figure 7 The end cap 2 has an inclined snap-fit ​​surface 27 on the side facing away from the mounting plate 42. The distance between the lower end of the snap-fit ​​surface 27 and the mounting plate 42 is less than the distance between the lower end of the snap-fit ​​surface 27 and the mounting plate 42. A recessed snap-fit ​​groove 28 is formed on the snap-fit ​​surface 27, and a snap-fit ​​block 432 that mates with the snap-fit ​​groove 28 is fixed on the side of the end cap 43 facing away from the mounting plate 42. Vertical hanging ears 23 are provided on both sides of the upper surface of the end cap 2.

[0055] Reference Figure 1 , Figure 4 and Figure 7 When installing end cap 2, first flip the buckle cover 43 upwards to open the quick-connect socket 4, then push the end cap 2 into the quick-connect socket 4, and then flip the buckle cover 43 downwards. The upper surface of the end cap 2 is engaged in the buckle groove 431, and the locking block 432 slides along the locking surface 27 until it is engaged in the locking groove 28. At this time, the end cap 2 cannot slide back and forth, thus limiting the end cap 2 and the housing 1.

[0056] The implementation principle of the modular quick-release filter cartridge housing for a laboratory pure water system according to the embodiment of this application is as follows: the operator selects the corresponding water receiving plate 5 and filter cartridge size according to the model of the pure water system. If a small filter cartridge is selected, the small filter cartridge is first connected to the support cylinder 6 and then installed in the housing 1; if a large filter cartridge is selected, the large filter cartridge is directly installed in the housing 1.

[0057] After selecting the appropriate water receiving plate 5, the operator installs the quick-connect socket 4 onto the pure water instrument. Then, the housing 1 is connected to the quick-connect socket 4. The quick-connect edge 211 is inserted into the quick-connect slot 411, and the connecting pipe 22 is connected to the water receiving pipe 51 one-to-one. The operator then flips the cover 43 and fastens it over the end cover 2.

[0058] Water from the pure water system flows from the inlet pipe 512 into the filter pipe 222, and then from the filter pipe 222 into the top of the purified water chamber 11, where it contacts the filter element. The filter element filters the water, and the water flows downward along the filter element until it reaches the purified water tank 31 in the base 3. The filtered water flows from the outlet tank 33 into the drain tank 32, and then from the drain tank 32 into the drain chamber. It then flows back through the drain pipe 223 to the outlet pipe 513, and finally back into the pure water system.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
