Technical Field
[0001] This utility model relates to the technical field of air conditioner protection filtration, specifically an air conditioner outlet protection filtration device. Background Technology
[0002] The air conditioner's protective filter uses built-in filter materials to intercept various pollutants in the air, reducing their entry into the room through the air conditioner's vents. It is also equipped with an activated carbon filter to absorb formaldehyde, TVOC, cooking fumes, pet odors, etc., improving indoor odor problems. Furthermore, the vent grille blocks objects from entering, preventing them from damaging objects and the air conditioner's interior.
[0003] According to the public announcement (CN221648721U), an air conditioner outlet protective filter device is disclosed. This technology discloses a technical solution that includes "an air outlet pipe and an outer frame, the outer frame being connected to the front end of the air outlet pipe, louvers being connected inside the outer frame, and an air outlet mechanism being connected to both the inner and outer ends of the air outlet pipe. The air outlet mechanism includes a filter unit and a disassembly unit, etc. It has the technical effect of sliding the fixed frame to the inner side of the slide groove, while the fixed plate moves to contact the upper side of the air outlet pipe and passes through the threaded rod, and then threading the cylinder to the outer side of the threaded rod until the lower end of the cylinder contacts the upper side of the fixed plate, fixing the fixed plate to the upper side of the air outlet pipe, thereby fixing the fixed frame and the activated carbon filter and HEPA filter therein to the inside of the air outlet pipe. When the air conditioner is turned on and air is blown out through the air outlet pipe, the airflow in the air outlet pipe is filtered by the activated carbon filter and HEPA filter between the two fixed frames before being blown out."
[0004] However, in the aforementioned comparative documents, the device achieves the filtration function of the air conditioner outlet through activated carbon filter and HEPA filter. However, after a period of use, both activated carbon filter and HEPA filter require frequent maintenance due to the adsorption of a large number of tiny particles to ensure the filtration effect of the device on the gas. Moreover, the filter structure is complicated to install and cumbersome to operate, making it inconvenient for widespread use.
[0005] Therefore, this utility model provides a protective filter device for air conditioning outlets. Summary of the Invention

[0012] In a preferred embodiment, the downward pressing arc surface is formed on the upper surface of the slider, and the upward pressing arc surface is formed on the lower surface of the slider.
[0013] The technical effect of adopting the above-mentioned further solution is that, by setting it so that when the slider is subjected to pressure in two directions, it will drive the slide plate to move outward, thereby releasing the lock of the filter frame.
[0014] In a preferred embodiment, a baffle is provided at the side end of the pipe, and a spacer strip is fixedly connected to the surface of the baffle.
[0015] The technical effect of adopting the above-mentioned further solution is that the inside of the pipeline is protected by setting baffles and spacers.

[0019] The technical advantage of adopting the above-mentioned further solution is that by setting the filter element to be replaced quickly when the filter element's filtration effect decreases, maintenance costs can be saved and the filter frame can be reused.
[0020] This utility model provides a protective filter device for air conditioning outlets. It has the following beneficial effects:
[0021] By pressing, the positioning block and the second spring steel strip are used to position the filter frame. After the filter has been used for a period of time and absorbed a large number of tiny particles, the third slide groove releases the positioning block from the filter frame after the filter frame is pressed again, thereby enabling the quick disassembly of the filter frame and ensuring the filtration effect of the device for air conditioning ventilation.
[0022] When the filter cartridge's filtration efficiency decreases, the cap can be opened by squeezing the clip to replace the filter cartridge, saving maintenance costs and allowing the filter frame to be reused. Attached Figure Description

[0030] 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.
[0031] like Figure 1 - Figure 5 As shown, this embodiment provides a technical solution: an air conditioner outlet protective filter device, including a pipe 1, a filter frame 2 slidably connected inside the pipe 1, a filter element 3 slidably connected inside the filter frame 2, the filter frame 2 and the filter element 3 being adapted to each other, a positioning mechanism is provided inside the pipe 1, the positioning mechanism includes a sliding plate 4, a first spring steel strip 5, a first sliding groove 6, a positioning block 7, a second sliding groove 8, a second spring steel strip 9, a third sliding groove 10, a slider 11, a lower pressing arc surface 12 and an upper pressing arc surface 13, the surface of the sliding plate 4 is slidably connected to the pipe 1, the sliding plate 4 is adapted to the pipe 1, and a first spring steel strip 5 is fixedly connected to the side end of the sliding plate 4. Spring steel bar 5 and first sliding groove 6 are formed on the inner wall of pipe 1. The two ends of the first spring steel bar 5 are slidably connected to pipe 1 through the first sliding groove 6. The first spring steel bar 5 drives the slide plate 4 to reset. The side end of the positioning block 7 is fixedly connected to the slide plate 4. During installation, the filter frame 2 is inserted into pipe 1. The positioning block 7 and the second spring steel bar 9 achieve the positioning effect. After the filter screen has been used for a period of time and absorbed a large number of small particles, the filter frame 2 is pressed again. The positioning block 7 releases the positioning of the filter frame 2 through the third sliding groove 10, thereby realizing the quick disassembly operation of the filter frame 2 and ensuring the filtration effect of the device for air conditioning ventilation.
[0032] like Figure 1 - Figure 4 As shown: The second groove 8 is opened on the inner wall of the pipe 1. The two ends of the second spring steel bar 9 are slidably connected to the pipe 1 through the second groove 8. After the second spring steel bar 9 is compressed, it provides an upward force to the filter frame 2 for support and positioning.
[0033] like Figure 1 - Figure 3 As shown: The third slide groove 10 is opened on the side end of the slide plate 4. The surface of the slider 11 is slidably connected to the slide plate 4 through the third slide groove 10. The slider 11 is adapted to the third slide groove 10. The slider 11 moves downward under the influence of gravity and moves upward when the lower end is pressed.
[0034] like Figure 1 - Figure 3As shown: The downward pressing arc surface 12 is formed on the upper surface of the slider 11, and the upward pressing arc surface 13 is formed on the lower surface of the slider 11. When the slider 11 is at the bottom of the slide plate 4, when the downward pressing arc surface 12 is subjected to downward pressure from the bottom of the filter frame 2, it drives the slide plate 4 to move outward until it is inserted into the interior of the filter frame 2. Then, the filter frame 2 drives the slider 11 to move upward to the upper end of the slider 11 and abut against the positioning block 7. The filter frame 2 presses the upward pressing arc surface 13, causing the upward pressing arc surface 13 to move outward again, thereby releasing the lock on the filter frame 2.
[0035] like Figure 1 As shown: A baffle 14 is provided on the side end of the pipe 1, and a spacer strip 15 is fixedly connected to the surface of the baffle 14. This is to prevent large objects from entering the interior of the pipe 1, thereby protecting it.
[0036] like Figure 1 - Figure 5 As shown: The upper end of the filter frame 2 is rotatably connected to the rotating shaft 16. The filter frame 2 is adapted to the rotating shaft 16. The side end of the rotating shaft 16 is fixedly connected to the cover 17. The upper end of the cover 17 is fixedly connected to the handle 18. The upper end of the filter frame 2 is fixedly connected to the locking post 19. The cover 17 can be rotated along the rotating shaft 16 to open, and the filter frame 2 can be lifted from the pipe 1 through the handle 18 to assist in replacement.
[0037] like Figure 1 - Figure 5 As shown: A clamp head 20 is fixedly connected to the upper end of the clamp post 19. The surface of the clamp head 20 is slidably connected to the cover 17. When the filtration effect of the filter element 3 decreases, the clamp head 20 can be squeezed to open the cover 17 and replace the filter element 3, saving maintenance costs and making the filter frame 2 reusable.
[0038] Working principle:
[0039] like Figure 1 - Figure 5 As shown:
[0040] During use: During installation, insert the filter frame 2 into the pipe 1. The lower end of the filter frame 2 presses against the positioning block 7, causing the slide plate 4 to move outward. After the positioning block 7 aligns with the groove of the filter frame 2, the first spring steel bar 5 is pushed inward, thereby achieving the positioning effect through the positioning block 7 and the second spring steel bar 9. After the filter screen has been used for a period of time and absorbed a large number of small particles, after pressing the filter frame 2 a second time, when the slider 11 is at the bottom of the slide plate 4, when the downward pressure on the lower arc surface 12 is applied by the bottom of the filter frame 2, it drives the slide plate 4 to move outward until it is inserted into the interior of the filter frame 2. Then, the filter frame 2 drives the slider 11 to move upward to the upper end of the slider 11 and press against the positioning block 7. The filter frame 2 presses against the upper arc surface 13, causing the upper arc surface 13 to move outward again, thereby releasing the lock on the filter frame 2. By setting the setting so that when the filtration effect of the filter element 3 decreases, the locking of the cover 17 can be released by pinching the clip 20. Then, the cover 17 can be rotated along the rotating shaft 16 to open and remove the filter element 3 for replacement, saving maintenance costs and allowing the filter frame 2 to be reused.
