[0024] 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.

[0025] like Figure 1 As shown;

[0026] A quick-release filter for a central air conditioning outlet includes a filter body 1.

[0027] In this embodiment: However, the traditional device lacks a quick disassembly design, and users need to use complex tools or steps when replacing or cleaning the filter screen, which not only consumes time and effort, but also may cause damage to the equipment due to improper operation. Due to the cumbersome disassembly process, users may reduce the frequency of cleaning and replacing the filter screen, causing the filter screen to be in a dirty state for a long time, which not only affects indoor air quality, but also affects the normal operation of the air conditioning system, increases energy consumption and failure rate. To solve this technical problem, a fixing assembly 2 is added on this basis.

[0028] Further:

[0029] As Figures 1 to 5 shown:

[0030] In combination with the above: The fixing assembly 2 includes a plug barrel 21, a limiting ring 22, and a plug rod 23. One end of the filter screen body 1 is detachably connected with the plug barrel 21. The outer side of the end of the plug barrel 21 is provided with the limiting ring 22. The inside of the plug barrel 21 is slidably connected with the plug rod 23. The inner side of the end of the plug barrel 21 is annularly provided with a plurality of limiting grooves 24. The end of the plug rod 23 is rotatably connected with a plurality of supporting legs 25. The supporting legs 25 are arranged on the inner side of the limiting grooves 24. One end of the plug rod 23 is fixedly connected with a pressing cap 26. One end of the plug rod 23 is fixedly connected with a plurality of first springs 27. One end of the first spring 27 is fixedly connected with one side of the supporting leg 25. The bottom end of the plug rod 23 is fixedly connected with a second spring 28. One end of the second spring 28 is fixedly connected with the bottom end of the plug barrel 21. One end of the supporting leg 25 is fixedly connected with a fixing cone 29. The fixing cone 29 is a conical structure. The material of the pressing cap 26 is silica gel.

[0031] In this embodiment: when the user uses the device, the filter screen body 1 can be installed in the corresponding position of the air conditioner. At this time, the through holes opened on the outer side of both ends of the filter screen body 1 are aligned with the adjustable connection holes. At this time, the insertion barrel 21 is inserted into the inner side of both ends of the filter screen body 1 and penetrates the mounting hole opened in the air conditioner, until one side of the supporting leg 25 abuts against the inner side of the mounting hole opened in the air conditioner. At this time, the quick installation and fixation of the filter screen body 1 are completed. When the user needs to quickly disassemble the filter screen body 1, the user only needs to press the pressing cap 26. The pressing cap 26 drives the insertion rod 23 to slide in the interior of the insertion barrel 21, while compressing the second spring 28. At this time, one end of the supporting leg 25 abuts against one end of the limiting groove 24, so that the supporting legs 25 rotate and shrink inward, while the first spring 27 is compressed. At this time, the supporting leg 25 is completely retracted into the interior of the insertion barrel 21. At this time, the insertion barrel 21 can be pulled out, and the filter screen body 1 can be quickly disassembled. The fixing cone 29 can increase the friction between the supporting leg 25 and the inner side of the air conditioner, and increase the fixation firmness. Through the fixing assembly 2, the user does not need to use special tools or complex steps, but only needs to use both hands to complete the replacement of the filter screen body 1, which greatly saves time and effort. For household users, this means that daily maintenance becomes easier. For commercial places such as office buildings, hotels, etc., the maintenance efficiency can be significantly improved, and the service interruption time caused by replacing the filter screen body 1 can be reduced. Due to the simple disassembly and assembly process, the user is more likely to frequently clean or replace the filter screen body 1, so as to maintain the continuous optimization of indoor air quality. Regular cleaning of the filter screen body 1 can effectively prevent dust, bacteria, pollen and other pollutants from entering the indoor, improve the indoor air quality, and protect the health of the residents and staff. Regular replacement of the clean filter screen body 1 can reduce the erosion of dust and impurities on the internal structure of the central air conditioner, reduce mechanical wear and tear, and prolong the service life of the entire air conditioning system. At the same time, the clean filter screen body 1 can also improve the working efficiency of the air conditioner and reduce energy consumption.
