[0033] The present application will be described below in conjunction with Figures 1-6 The present application discloses a filter cartridge device which is easy to disassemble and assemble.

[0034] As Figure 1 , Figure 2 and Figure 3 shown, in one embodiment, a filter cartridge device which is easy to disassemble and assemble, comprising a filter cartridge body 100, a filter adapter 200, a filter cartridge assembly 300, a cover plate 400 and a connecting column 500.

[0035] The filter cartridge body 100 has an air inlet column 110 and an air outlet column 120 at the bottom, and has an airflow passage 130 inside.

[0036] The filter adapter 200 is installed in the cavity of the laser body 10, has a threaded hole 210, a mounting hole 230 and a positioning hole 220 which is interference fit with the air inlet column 110 or the air outlet column 120, and the threaded hole 210 and the positioning hole 220 are in communication with each other.

[0037] The positioning hole 220 is used to position the position of the air inlet column 110 or the air outlet column 120, and the threaded hole 210 is used to install the pipe joint.

[0038] The filter core assembly 300 is installed in the airflow channel 130.

[0039] In operation, the gas enters the airflow channel 130 from the filter adapter 200 on the air inlet column 110, is filtered by the filter core assembly 300, and then exits from the filter adapter 200 on the air outlet column 120.

[0040] The cover plate 400 is detachably connected to one end of the filter core body 100.

[0041] The cover plate 400 can be fixed to one end of the filter core body 100 by screw connection or buckle connection.

[0042] The connecting column 500 is fixed in the cavity of the laser body 10 and penetrates the filter core body 100, and the free end of the connecting column 500 extends to the surface of the filter core body 100.

[0043] The connecting column 500 and the surface of the filter core body 100 are both provided with bolt holes 160.

[0044] In installation, the two filter adapters 200 are installed in the cavity of the laser body 10 by screws, then the air inlet column 110 is inserted into one of the filter adapters 200, the air outlet column 120 is inserted into the other filter adapter 200, and the filter core body 100 is fixed with the connecting column 500 by bolts; when replacing the filter core body 100, only the bolts in the bolt holes 160 are removed, then the old filter core body 100 is pulled out from the positioning hole 220, then the new filter core body 100 is inserted into the positioning hole 220, and the filter core body 100 is fixed with the connecting column 500 by bolts; when replacing the filter core assembly 300, only the cover plate 400 is detached from one end of the filter core body 100, then the old filter core assembly 300 is taken out from the airflow channel 130, and the new filter core assembly 300 is inserted into the airflow channel 130.

[0045] The filter core device with convenient disassembly and assembly, on the one hand, replaces the traditional filter core directly connected with air pipes at both ends in the dehumidification structure with the filter adapter 200, so that the pipe does not need to be disassembled when the filter core body 100 is replaced each time, the replacement efficiency is improved, and the risk of pipe damage is reduced, on the other hand, the split filter adapter 200 assembly can adapt to the distance between the air inlet column 110 and the air outlet column 120 on different models of filter core bodies 100, so that the machining precision requirement and the weight of the filter core body 100 are reduced.

[0046] In this embodiment, referring to Figure 4 , the central axis of the threaded hole 210 and the central axis of the positioning hole 220 are perpendicular to each other, which facilitates the installation of the pipe joint.

[0047] In the embodiment, when the air inlet column 110 or the air outlet column 120 is clamped in the corresponding positioning hole 220, the first sealing ring 240 is arranged between the air inlet column 110 or the air outlet column 120 and the corresponding filter adapter 200.

[0048] By arranging the first sealing ring 240 between the air inlet column 110 and the filter adapter 200 and between the air outlet column 120 and the filter adapter 200, the sealing performance of the filter element body 100 after being assembled with the filter adapter 200 is improved. Meanwhile, the guide angle is arranged at the threaded hole 210 and the positioning hole 220 of the filter adapter 200, so that the assembly of the first sealing ring 240 is more convenient and the damage of the first sealing ring 240 is less likely to occur.

[0049] In the embodiment, referring to Figure 5 , the filter element assembly 300 comprises a first partition plate 310 and a second partition plate 320, and a filter material 330 is fixed between the first partition plate 310 and the second partition plate 320. The first partition plate 310 and the second partition plate 320 are both provided with a through hole 340, and a filter paper 360 is arranged between the filter material 330 and the first partition plate 310 or the second partition plate 320.

[0050] It should be noted that, in order to improve the filtering performance of the filter element assembly 300, a third partition plate is arranged in the middle of the filter material 330, and a filtering hole is arranged on the third partition plate. The filter material 330 on both sides of the third partition plate can be made of different materials according to the needs. Meanwhile, the filter paper 360 arranged between the filter material 330 and the first partition plate 310 or the second partition plate 320 can prevent the powder of the filter material 330 from leaking out.

[0051] In the embodiment, referring to Figure 6 , the first partition plate 310 and the second partition plate 320 are both partition plates with bosses, and the first partition plate 310 and the second partition plate 320 are mirror-symmetric.

[0052] Through the design of the shapes of the first partition plate 310 and the second partition plate 320, the flow efficiency of the airflow can be improved, so that the airflow to be filtered can quickly enter the airflow channel 130.

[0053] In the embodiment, a compression spring 350 is arranged between the second partition plate 320 and the cover plate 400, and the compression spring 350 can make the gap inside the filter material 330 as small as possible.

[0054] In the embodiment, the surface of the filter element body 100 is provided with an observation hole 140, and a transparent window 150 is threadedly connected in the observation hole 140.

[0055] The transparent window 150 is made of transparent acrylic plate, which is used to observe the color of the internal filter material 330, so as to determine whether the filter material 330 needs to be replaced.

[0056] In the embodiment, the second sealing ring 410 is arranged between the transparent window 150 and the filter element body 100 and between the cover plate 400 and the filter element body 100.

[0057] By adding the second sealing ring 410 between the transparent window 150 and the filter element body 100 and between the cover plate 400 and the filter element body 100, the sealing performance of the filter element body 100 is improved.

[0058] The specific application scenarios are as follows:

[0059] Referring to Figure 1 and Figure 2 , the dehumidification system in the laser body 10 is composed of pipe joints 20 / 21 / 22 / 23, pipelines 30 / 31 / 32, an air pump 40 and a filter element device. When the filter system is working, the air pump 40 draws out the humid air in the cavity through the pipe joint 20 and the pipeline 30, and then sends the humid air into the filter element device through the pipeline 31 and the pipe joint 21. After passing through the filter material 330 in the filter element device, the humid air becomes dry air, and then the dry air returns to the cavity through the pipe joint 22, the pipeline 32 and the pipe joint 23. The pipe joint 20 and the pipe joint 23 are fixed on the cavity of the laser body 10, and connect the space inside the cavity which needs to be dehumidified. The pipe joint 21 and the pipe joint 22 are fixed in the threaded hole 210 of the filter adapter 200, and the air pump 40 and the filter element device are fixed on the cavity.

[0060] When installing, a filter adapter 200 is installed in the laser cavity by a screw, and the air outlet column 120 is inserted into another filter adapter 200, and then the air inlet column 110 is inserted into the filter adapter 200 which has been installed in the laser cavity. The filter adapter 200 on the air outlet column 120 is adjusted to be aligned with the threaded hole on the laser cavity, and at this time, the first sealing ring 240 between the filter adapter 200 and the filter element body 100 is in a relatively appropriate state. The two mounting holes 230 of the filter adapter 200 connected by the air outlet column 120 which are not covered by the filter element body 100 are fixed, then the filter element body 100 is pulled out, and then the other two mounting holes 230 of the other filter adapter 200 are fixed. Compared with the scheme of arranging two air path channels on one structural member and directly connecting the filter element body 100, this method of using two filter adapters 200 has two advantages. One is to reduce the machining precision requirement. The split assembly can adapt to the distance between the air inlet column 110 and the air outlet column 120 on the filter element body 100. The other is to reduce the weight. In order to improve the service life, the filter element body 100 should be as large as possible, and the split filter adapter 200 only needs to maintain the current size and does not need to be increased.

[0061] When replacing the filter core body 100, first open the outer cover of the laser body 10, remove the fixing bolt of the old filter core body 100, and then directly pull out the old filter core body 100. If the space is not enough, the bolt can be screwed in the bolt hole 160 of the old filter core body 100 to pull out the old filter core body 100. Then insert the new filter core body 100 into the connecting column 500, and the connecting column 500 plays a guiding and limiting role, so that the air inlet column 110 and the air outlet column 120 of the filter core body 100 can be easily aligned with the positioning hole 220 on the two filter adapters 200. The positioning hole 220 on the filter adapter 200 is provided with a guide angle, so that the assembly of the first sealing ring 240 is more convenient, and the damage of the first sealing ring 240 is less likely to occur. After the new filter core body 100 is inserted into position, it can be fixed on the connecting column 500 by a bolt. Cover the outer cover of the laser body 10, and the replacement of the filter core body 100 is completed. The whole process does not need to insert the air flow pipeline, greatly improves the replacement efficiency, and reduces the risk of damage to the air flow pipeline.

[0062] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0063] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
