[0022] 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.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] An air conditioning filter replacement device includes a housing, which includes an air conditioning fan 1. A filter cover 11 is provided inside the air conditioning fan 1. By setting the air conditioning fan 1, the air conditioning fan 1 can maintain a certain temperature and humidity in the regulated space. The filter cover 11 can filter dust, particulate matter and other particles in the air, thereby improving indoor air quality.

[0025] A replacement mechanism is provided on the inner side of the filter cover 11. The replacement mechanism includes a fixed frame 2, which is fixedly connected to the inner wall of the air conditioner fan 1. A first movable groove 21 is opened on the inner side of the filter cover 11. A movable block 22 is movably connected to the inner side of the first movable groove 21. An insert block 23 is fixedly connected to the surface of the movable block 22. A slot 24 is opened on the inner wall of the air conditioner fan 1. A first spring 25 is fixedly connected to the surface of the movable block 22. A connecting block 26 is fixedly connected to the lower surface of the movable block 22. By moving the movable block 22 and the insert block 23 in the first movable groove 21, the insert block 23 and the slot 24 can be inserted and separated, which facilitates the quick disassembly and assembly of the filter cover 11 and the air conditioner fan 1, thereby facilitating the replacement of the filter cover 11 and ensuring the filtration effect of the filter cover 11.

[0026] Furthermore, four sets of first movable slots 21 are provided on the inner side of the filter cover 11. Movable blocks 22 and insert blocks 23 are both movable on the inner side of the first movable slots 21. Four sets of slots 24 are provided on the inner wall of the air conditioner fan 1. By setting the slots 24, the movable blocks 22 can be reset, and the insert blocks 23 can be reset and inserted into the slots 24, which can fix the filter cover 11 and facilitate the installation and use of the filter cover 11.

[0027] Furthermore, one end of the first spring 25 is fixedly connected to the first movable groove 21, and the other end of the first spring 25 is fixedly connected to the movable block 22. The two sets of movable blocks 22 are correspondingly connected to the connecting block 26. By setting the connecting block 26, pulling the connecting block 26 can move the two sets of movable blocks 22, thereby facilitating the separation of the insert block 23 and the slot 24, making it easier to remove the filter cover 11 from the air conditioner fan 1, and making the replacement operation of the filter cover 11 convenient.

[0028] Furthermore, a limiting mechanism is provided on the surface of the air conditioner fan 1. The limiting mechanism includes a fixed block 3, which is fixedly connected to the surface of the air conditioner fan 1. A sliding groove 31 is provided on the inner side of the fixed block 3. A slider 32 is movably connected to the inner side of the sliding groove 31. A stop block 33 is fixedly connected to the surface of the slider 32. A second movable groove 34 is provided on the inner wall of the sliding groove 31. A second spring 35 is fixedly connected to the inner wall of the second movable groove 34. A locking block 36 is fixedly connected to the surface of the second spring 35. A locking groove 37 is provided on the inner side of the slider 32. By moving the slider 32 in the sliding groove 31 and engaging the locking groove 37 with a set of locking blocks 36 on the inner side of the fixed block 3, the stop block 33 can be fixed. This makes it easier for the stop block 33 to limit the bottom of the filter screen cover 11, making the filter screen cover 11 less likely to fall off, thus achieving a better fixing effect.

[0029] Furthermore, the fixed blocks 3 are fixedly connected to the air conditioner fan 1 in two sets, the sliding grooves 31 are opened in two sets on the inner side of the fixed blocks 3, and the sliders 32 are fixedly connected to the two ends of the stop block 33 in two sets. The end of the slider 32 away from the stop block 33 moves in the inner side of the sliding groove 31. Through the opening of the sliding groove 31 and the setting of the slider 32, the stop block 33 can move stably when it is pushed.

[0030] Furthermore, two sets of second movable grooves 34 are formed on the inner wall of the slide groove 31, and eight sets of second springs 35 are connected to the second movable grooves 34 respectively. The two ends of the second springs 35 are respectively connected to the second movable grooves 34 and the locking blocks 36. The locking blocks 36 move inside the second movable grooves 34. By forming two sets of second movable grooves 34 inside the slide groove 31 and correspondingly setting the second springs 35 and locking blocks 36, the locking blocks 36 can move in the second movable grooves 34 under the elastic properties of the second springs 35, thereby enabling them to engage and disengage with the locking grooves 37, thus facilitating the fixing of the stop block 33 in the required position.

[0031] Working principle: When in use, pulling the connecting block 26 allows the movable block 22 to move inside the first movable groove 21 under the action of the connecting block 26. Consequently, the insert block 23 moves and separates from the slot 24. At this time, the first spring 25 is in a contracted state, which releases the fixation of the air conditioner fan 1 and the filter cover 11, allowing the filter cover 11 to be removed and replaced. When the filter cover 11 needs to be installed, place the filter cover 11 into the air conditioner fan 1 and make the upper surface of the filter cover 11 contact the lower surface of the fixing frame 2. Then release the connecting block 26, and the movable block 22 will reset under the rebound action of the first spring 25. Consequently, the insert block 23 resets and engages with the slot 24, thus achieving the fixed installation of the filter cover 11.

[0032] By pushing the stop block 33, the stop block 33 slides inside the slide groove 31 via the slider 32. When the slider 32 moves and contacts a set of locking blocks 36 inside the slide groove 31, the locking blocks 36 are squeezed and move into the second movable groove 34. At this time, the second spring 35 is in a contracted state. When the slider 32 moves so that the locking groove 37 faces the locking block 36, the locking block 36 is reset under the rebound action of the second spring 35 and engages with the locking groove 37, thereby fixing the position of the stop block 33, that is, the stop block 33 is located under the filter screen cover 11. On the surface, the filter cover 11 is limited and blocked, making it less likely to fall off. By pushing the stop block 33, the slider 32 on the stop block 33 and the locking block 36 in the inner group of the slide groove 31 are disengaged. Through the elastic property of the second spring 35 and the locking block 36 in the outer group of the slide groove 31, the stop block 33 can be moved away from under the filter cover 11 and fixed under the air conditioner fan 1. This allows the stop block 33 to release its limitation and obstruction of the filter cover 11, thus not affecting the disassembly and assembly of the filter cover 11.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
