Technical Field

[0001] This utility model belongs to the field of air conditioning filtration technology, and in particular relates to an air conditioning outlet air filtration device. Background Technology

[0002] An air conditioner vent filter is a washable or replaceable filter device installed at the air conditioner vent. It is usually made of materials such as metal mesh, nylon mesh, or non-woven fabric. Its main function is to filter particulate matter such as dust, bacteria, and pollen in the air, prevent pollutants from entering the room and improve air quality, while protecting the internal air conditioning system from dust corrosion, maintaining operating efficiency and extending service life.

[0003] Existing central air conditioning systems generally have filters installed at the air inlet to purify the incoming air. However, during the operation of the air conditioner, dust, bacteria, or mold may still accumulate in its internal air ducts, heat exchanger fins, and other components. These pollutants will be blown into the indoor environment with the air conditioner's exhaust. Therefore, filters are installed at the air outlet to filter dust and avoid affecting indoor air quality. However, existing air conditioner exhaust filters are prone to clogging after a period of use, and the air conditioner exhaust outlet is usually located at a high position, making disassembly and cleaning troublesome and inconvenient for users.

[0004] To address these issues, we provide an air conditioning outlet filter device. Utility Model Content

After releasing the lock of the two limit locking mechanisms 52, the user can quickly remove dust filter plate 51 and dump the dust on its top.

[0028] Example 2

[0029] Please see Figure 1-5Based on Embodiment 1, the limiting and locking mechanism 52 includes two sliding rods 521. The front side of the sliding rod 521 is fixedly connected to the ash discharge pipe 3. Sliding sleeves 522 and springs 523 are respectively fitted on both sides of the surface of the sliding rod 521. A retaining plate 524 is fixedly connected to the bottom of the sliding sleeve 522. The top of the retaining plate 524 contacts the dust filter plate 51. Handles are fixedly connected to opposite sides of the two retaining plates 524. Both sides of the sliding rod 521 are fixedly connected to the ash discharge pipe 3 through mounting plates. The adjusting mechanism 42 includes a control housing 421. The bottom of the control housing 421 is fixedly connected to the frame 1. A servo motor 422 is fixedly connected to the left side of the inner cavity of the control housing 421. A connecting plate 423 is fixedly connected to the right side of the output end of motor 422. The front side of the connecting plate 423 penetrates the control housing 421 and is fixedly connected to the sealing cover 41. The vibration mechanism 46 includes a rotary motor 461. The front side of the rotary motor 461 is fixedly connected to the inner wall of the sealing cover 41. A rotating shaft 462 is fixedly connected to the bottom of the output end of the rotary motor 461. Elastic rubber rods 463 are fixedly connected to both sides of the rotating shaft 462. A fixing plate is movably connected to the bottom of the rotating shaft 462 through a bearing. The front side of the fixing plate is fixedly connected to the inner wall of the sealing cover 41. Connecting pieces are fixedly connected to the top and bottom of both sides of the frame 1. Mounting holes are opened on the front side of the connecting pieces.

[0030] Specifically: the slide bar 521 and slide sleeve 522 cooperate with the spring 523 to control the position of the clamping plate 524, allowing the clamping plate 524 to limit and fix the dust filter plate 51, ensuring its stable installation at the bottom of the ash discharge pipe 3. The user can remove the dust filter plate 51 by pushing the two clamping plates 524 to empty the filtered dust. The top of the clamping plate 524 can hold the dust filter plate 51 in the ash discharge pipe 3. The handle allows the user to pull the two clamping plates 524, releasing the clamping plates from limiting and fixing the dust filter plate 51. The mounting plate increases the stability of the slide bar 521 installation. The control housing 421 facilitates the use of the servo motor. The installation and fixing of 422: the servo motor 422 can cooperate with the connecting plate 423 to control the use angle of the sealing cover 41. When the air conditioner is exhausting air, it can be in the unfolded state, and when cleaning is required or the air conditioner is not working, it is in the sealed state.

During the rotation, the elastic rubber rods 463 can continuously strike the filter screen 2, causing the dust attached to its surface to be shaken off. The fixing plate is used to improve the stability of the rotating shaft 462 during the rotation process and prevent it from swinging during rotation. The connecting plate and mounting hole can stably install the frame 1 at the air conditioner outlet.

[0031] The working principle of this utility model is as follows: The frame 1 is installed at the air outlet of the air conditioner, and the filter screen 2 filters the airflow. When the air conditioner stops running or when the filter screen 2 needs to be cleaned, the servo motor 422 drives the connecting plate 423 to rotate, causing the sealing cover 41 to close and cover the front side of the frame 1. At this time, the rotary motor 461 starts, and the rotary motor 461 drives the rotating shaft 462 to rotate. The elastic rubber rods 463 on both sides of the rotating shaft 462 continuously beat the surface of the filter screen 2 as it rotates. At the same time, the electric push rod 44 pushes the piston 45 to move inside the exhaust cover 43. The movement of the piston 45 generates a reverse airflow to flush the mesh of the filter screen 2. The dust clogging the surface and mesh of the filter screen 2 is dislodged under the vibration and airflow flushing, without the need for the user to disassemble the filter. The filter screen 2 is cleaned automatically, and the loose dust falls to the dust discharge pipe 3 at the bottom of the frame 1. The dust falls through the dust discharge pipe 3 to the top of the dust filter plate 51. The dust filter plate 51 is fixed to the outlet of the dust discharge pipe 3 by the limiting locking mechanism 52. When the dust needs to be emptied, the user holds the handle and pulls the two side plates 524 outward. The plates 524 are released from the limiting position on the dust filter plate 51, and the dust filter plate 51 can be taken down to empty the dust. After cleaning, the dust filter plate 51 is reinserted into the dust discharge pipe 3. The spring 523 returns to its original position and pushes the plates 524 to automatically lock the dust filter plate 51. When the air conditioner is running again, the servo motor 422 drives the sealing cover 41 to rotate and open through the connecting plate 423, so that the airflow can pass through the filter screen 2 normally.
