[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This utility model provides a modular air conditioning unit that facilitates filter replacement. The operator manually moves the sliding rod horizontally, causing the baffle to move synchronously, releasing the position restriction on the filter. At this point, the spring is compressed, allowing the filter to be removed from the rectangular slot. A new filter is then slid into the rectangular slot. The sliding rod is then released, and as the spring returns to its original shape, it moves in the opposite direction and resets, causing the baffle to reset synchronously and reposition the filter. The filter is now replaced. This design facilitates filter replacement and is simple and efficient. Attached Figure Description

[0019] 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.
[0020] To address the issue of how to facilitate technology replacement, such as Figure 1-4 As shown, the following preferred technical solutions are provided:
[0021] A modular air conditioning unit that facilitates filter replacement includes an air conditioning unit body 1. The air conditioning unit body 1 includes a housing 2. A rectangular groove 3 is formed in the side wall of the housing 2. A filter screen 5 is slidably disposed in the rectangular groove 3. A slide rod 8 is horizontally disposed on the outer side of the housing 2. A baffle 9 is fixedly disposed at the end of the slide rod 8. A spring 11 is sleeved on the outer side of the slide rod 8. The slide rod 8 can reciprocate linearly in the horizontal direction to limit or release the position of the filter screen 5.
[0022] Specifically, the operator manually moves the slide bar 8 horizontally, causing the baffle 9 to move synchronously, releasing the position restriction on the filter screen 5. At this time, the spring 11 is compressed, and the filter screen 5 is then removed from the rectangular groove 3. A new filter screen 5 is slid into the rectangular groove 3, and then the slide bar 8 is released. As the spring 11 returns to its original deformation, it drives the slide bar 8 to move in the opposite direction and reset, causing the baffle 9 to reset synchronously and re-restrict the position of the filter screen 5. At this point, the filter screen 5 has been replaced. The purpose of this design is to facilitate the replacement of the filter screen 5, making the operation simple and efficient.
[0023] Furthermore, such as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:
[0024] Two fixed plates 7 are symmetrically arranged on the outer side of the slide rod 8. The fixed plates 7 are fixedly connected to the outer side of the outer shell 2. The slide rod 8 is slidably connected to the two fixed plates 7. A circular plate 10 is fixedly provided at the end of the slide rod 8 away from the baffle 9. A spring 11 is fastened between the side of the circular plate 10 and the side of the adjacent fixed plate 7. The baffle 9 is slidably connected to the outer side of the outer shell 2. The purpose of this design is to ensure that the slide rod 8 can move horizontally back and forth in a straight line. Driven by the spring 11, the slide rod 8 drives the baffle 9 to move, thus limiting the position of the filter screen 5.
[0025] Furthermore, such as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:
[0026] A rotating ring 12 is rotatably connected to the outside of the slide rod 8 via a bearing. A connecting plate 13 is formed on the outside of the rotating ring 12. The rotating ring 12 is located between two fixed plates 7. A limiting plate 15 is horizontally fixed on the outer side of the outer shell 2. The limiting plate 15 is located at the lower end of the two fixed plates 7. Multiple evenly distributed limiting grooves 16 are horizontally opened inside the limiting plate 15. The purpose of this design is to manually rotate the connecting plate 13 away from the limiting groove 16 and move the slide rod 8 horizontally, and then rotate the connecting plate 13 into the corresponding limiting groove 16 to fix the position of the slide rod 8.
[0027] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:
[0028] The connecting plate 13 has a rectangular hole 14 inside. The purpose of this design is to allow fingers to pass through the rectangular hole 14 to rotate the connecting plate 13.
[0029] Furthermore, such as Figure 3 and Figure 4 As shown, the following preferred technical solutions are provided:
[0030] The outer casing 2 has a rectangular plate 4 inside, and the filter screen 5 is fixedly installed inside the rectangular plate 4. The rectangular plate 4 and the inner side of the rectangular groove 3 are interlocked and matched in size. The purpose of this design is to install the filter screen 5 by inserting the rectangular plate 4 into the rectangular groove 3.
[0031] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0032] A handle 6 is fixedly connected to the middle of the outer side of the rectangular plate 4. The outer side of the handle 6 is machined with anti-slip texture. The purpose of this design is to facilitate the taking and putting away of the rectangular plate 4 through the handle 6.
[0033] In summary: The operator manually moves the slide bar 8 horizontally, causing the baffle 9 to move synchronously, releasing the position restriction on the filter screen 5. At this time, the spring 11 is compressed, allowing the filter screen 5 to be removed from the rectangular groove 3. A new filter screen 5 is then slid into the rectangular groove 3. The slide bar 8 is then released, and as the spring 11 returns to its original shape, it drives the slide bar 8 to move in the opposite direction and reset, causing the baffle 9 to reset synchronously and reposition the filter screen 5. The filter screen 5 is now replaced. This design facilitates filter screen replacement, offering simple and efficient operation.
