[0027] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0028] like Figure 1 As shown, this utility model provides a fully automatic air filter cleaning device, comprising: The sealed cleaning tank 1 includes a tank body 2. A rotary motor 3 is installed at the bottom of the tank body 2. A filter element positioning and fixing ring is rotatably installed inside the tank body 2. The filter element positioning and fixing ring is connected to the output end of the rotary motor 3. The inner side of the filter element positioning and fixing ring is used to connect with the air filter element 4 to be cleaned. The air supply structure includes a compressor 5 and an air guide pipe 6. The air outlet of the compressor 5 is connected to one end of the air guide pipe 6, and the other end of the air guide pipe 6 extends into the interior of the air filter element 4 to be cleaned. The dust collection structure includes a vacuum cleaner 7 and a suction pipe 8. The suction end of the vacuum cleaner 7 is connected to one end of the suction pipe 8, and the other end of the suction pipe 8 is connected to the inside of the tank 2. The control unit is connected to the rotary motor 3, compressor 5 and vacuum cleaner 7.

[0029] Specifically, the cleaning device comprises three parts: a sealed cleaning tank 1, an air supply structure, and a dust collection structure. The air filter 4 is placed in the sealed cleaning tank 1. The air supply mechanism provides compressed air to the tank 2, allowing the compressed air to blow dust from inside the air filter 4, pushing residual dust onto the filter 4 into the tank 2. The dust collection structure then collects the dust from the tank 2 for centralized processing, preventing dust from scattering and affecting the surrounding environment. Throughout the cleaning process, workers will not come into contact with dust, improving their comfort. The cleaning device includes a control unit. After the air filter 4 is installed on the filter positioning ring, the control unit can start the rotary motor 3, compressor 5, and vacuum cleaner 7, enabling the air filter 4 to clean automatically. After the cleaning device has run for a certain period, the control unit can shut down all structures, remove the air filter 4 for inspection, and reuse it after passing inspection. When the cleaning device blows air to clean the air filter 4, the rotating motor 3 drives the air filter 4 to rotate, and the air outlet of the air duct 6 is located inside the air filter 4. This allows air to be delivered to the inside of the air filter 4 from different angles, enabling a thorough cleaning of the air filter 4.

[0030] like Figures 3 to 4 As shown, the filter element positioning and fixing ring includes a cross bracket 9 and a circular ring 10. The center of the cross bracket 9 is connected to the rotary motor 3. The four ends of the outer periphery of the cross bracket 9 are connected to the inner periphery of the circular ring 10. The outer periphery of the circular ring 10 is provided with four fixing clips 11, which abut against the outer surface of the air filter element 4 to be cleaned.

[0031] Specifically, the filter element positioning and fixing ring is connected to the output end of the rotary motor 3. The cross bracket 9 and the ring 10 are located at the bottom of the air filter element 4. In this way, the ring 10 can support the air filter element 4 and rotate it. Four fixing clips 11 are evenly arranged on the outer circumference of the ring 10. After the fixing clips 11 are closed, they can hold the bottom outer circumference of the air filter element 4 tightly, thus driving the air filter element 4 to rotate.

[0032] like Figures 5 to 6 As shown, the cross bracket 9 is composed of four support rods 12 spliced ​​together. The support rods 12 are hollow structures, and each support rod 12 has a pull wire 13 threaded through it. One end of the pull wire 13 is connected to the fixing clip 11. A spring 14 is provided between the fixing clip 11 and the ring 10. An operation hole is opened at the center of the cross bracket 9, and an operation button 15 is provided in the operation hole. The operation button 15 is connected to the other end of all the pull wires 13.

[0033] Specifically, the four fixing clips 11 are aligned with the four support rods 12 of the cross bracket 9. A pull wire 13 passes through the inside of each support rod 12. One end of the pull wire 13 is connected to the operating button 15 at the center of the cross bracket 9, and the other end is connected to each of the four fixing clips 11. Under the action of the spring 14, the fixing clips 11 open outwards along the direction of the support rods 12. When it is necessary to close all four fixing clips 11 simultaneously, the operating button 15 needs to be lifted. This causes the pull wire 13 to pull the fixing clips 11 towards the center, compressing the spring 14. Finally, rotating the operating button 15 90°... The two ends of the operating button 15 are engaged with the outer periphery of the operating hole, and the pull cord 13 will not retract under the action of the spring 14. The fixing clip 11 remains closed, holding the central air filter 4 tightly in place. After the air filter 4 is cleaned, the operating button 15 is rotated 90° in the opposite direction. In this way, the operating button 15 does not interfere with the outer periphery of the operating hole, and the operating button 15 can retract into the operating hole. The pull cord 13 no longer pulls the fixing clip 11, and the fixing clip 11 moves away from the fixing ring again under the action of the spring 14. The air filter 4 is no longer restricted by the fixing clip 11, and the air filter 4 can be removed from the tank 2.

[0034] like Figures 1 to 2 As shown, the filter element positioning and fixing ring also includes a limiting ring 16. The outer periphery of the limiting ring 16 is connected to the inner wall of the tank 2. A rotating ring 17 is rotatably provided on the inner periphery of the limiting ring 16. The inner side of the rotating ring 17 cooperates with the outer surface of the air filter element 4 to be cleaned.

[0035] Specifically, another part of the structure, the filter element positioning and fixing ring, is also set at the middle height of the tank body 2: the outer circumference of the limiting ring 16 is fixedly connected to the inner wall of the tank body 2, and the inner circumference of the limiting ring 16 is rotatably provided with a rotating ring 17. When the air filter element 4 is placed in the tank body 2, the air filter element 4 is inside the rotating ring 17, and there is a 2~3mm gap between the outer circumference of the air filter element 4 and the inner circumference of the rotating ring 17, so as not to affect the normal installation of the air filter element 4; after the air filter element 4 is installed in place in the tank body 2, the fixing clip 11 closes and fixes the air filter element 4. During the rotation of the air filter element 4, it will... Compressed air blows onto the inner circumferential surface of the air filter element 4. When there is too much dust in a certain direction, the compressed air will blow the air filter element 4 off-center, causing it to come into contact with the rotating ring 17. The rotating ring 17 then limits the movement of the air filter element 4, preventing it from separating from the fixing clip 11 due to excessive tilt. The rotating ring 17 and the limiting ring 16 are also designed to rotate relative to each other. Even if the air filter element 4 is blown against one side of the rotating ring 17 by the compressed air, it will not create resistance to rotation, ensuring normal rotation and successful cleaning of the air filter element 4. Ball bearings are installed between the limiting ring 16 and the rotating ring 17, allowing them to rotate relative to each other.

[0036] like Figure 1 As shown, the top of the tank body 2 is provided with an openable and closable hatch 18, and a connecting hole is provided at the center of the hatch 18. The air guide pipe 6 is inserted through the connecting hole, and a sealing ring 19 is provided between the air guide pipe 6 and the connecting hole.

[0037] Specifically, during the cleaning process of the air filter 4, the canister 2 needs to be kept sealed to prevent dust from the air filter 4 from spreading to the surrounding environment. When the air filter 4 is installed in the canister 2, open the top door 18. After confirming that the air filter 4, cross bracket 9, and ring 10 are installed in place, lift and rotate the operating button 15 to make the fixing clip 11 close to the outer surface of the air filter 4. Then close the door 18, insert the air duct 6 into the connecting hole, and finally start the rotary motor 3, compressor 5, and vacuum cleaner 7 through the control unit to clean the air filter 4. The sealing ring 19 can seal the gap between the air duct 6 and the door 18 to ensure that dust does not spread outside the canister 2.

[0038] like Figures 1 to 2 As shown, an exhaust pipe 21 is provided at the other end of the air guide pipe 6. Multiple air outlets are evenly arranged on the outer periphery of the exhaust pipe 21. The exhaust pipe 21 is arranged along the axial direction of the air filter element 4 to be cleaned.

[0039] Preferably, the length of the air outlet is matched with the height of the air filter element 4 to be cleaned.

[0040] Preferably, the rotation angle of the rotary motor 3 is 360°.

[0041] Specifically, the connecting hole is located at the center of the hatch 18. After inserting the air guide pipe 6 into the position of the connecting hole, the exhaust pipe 21 can be located at the axis of the air filter element 4. The air outlet of the exhaust pipe 21 is at the same height as the filter screen of the air filter element 4. The tank 2 can be made of transparent acrylic sheet, so that it can be confirmed that the air outlet is facing the filter screen of the air filter element 4. The air outlet is distributed on the outer peripheral surface of the exhaust pipe 21. The air outlet can deliver air to the inner peripheral surface of the air filter element 4 in 360°. With the continuous rotation of the air filter element 4, compressed air can be delivered to the air filter element 4 from different angles, improving the cleanliness of the air filter element 4.

[0042] like Figures 7 to 8 As shown, in the second embodiment, the exhaust pipe 21 inside the tank 2 is configured in another form. The length of the air outlet on the exhaust pipe 21 is less than the height of the air filter 4 to be cleaned. A telescopic motor 22 is also provided on the door 18. The output end of the telescopic motor 22 is connected to the exhaust pipe 21. The air pressure of the compressor 5 is less than the suction power of the vacuum cleaner 7.

[0043] Specifically, besides setting the distribution area of ​​the air outlet on the exhaust pipe 21 to be the same height as the filter screen of the air filter element 4, the length of the exhaust pipe 21 in the filter cleaning device can be set to be shorter than the height of the air filter element 4. Then, a telescopic motor 22 is installed on the lower side of the door 18. The telescopic end of the telescopic motor 22 is connected to the end of the exhaust pipe 21 near the air guide pipe 6. No air outlet is opened at the connection position between the telescopic end and the exhaust pipe 21, so that the connection between the telescopic motor 22 and the exhaust pipe 21 will not affect the air outlet's airflow to the air conditioning filter element 4. After the air conditioning filter element 4 is installed in place in the tank 2, the door 18 is installed on the top of the tank 2 to seal it. The telescopic motor 22 is then powered on and connected, and then the compressor... 5. Air is supplied to the air conditioning filter 4. The rotary motor 3 drives the air conditioning filter 4 to rotate. The vacuum cleaner 7 extracts air from the tank 2. In order to clean the air conditioning filter across its entire height, the telescopic motor 22 is started and drives the exhaust pipe 21 to move up and down. This way, the air supply range of the air outlet covers the entire inner side of the air conditioning filter 4, achieving a comprehensive cleaning of the air conditioning filter. The air guide pipe 6 is made of flexible material, while the exhaust pipe 21 is made of rigid material. While the telescopic motor 22 drives the exhaust pipe 21 to move up and down, the air guide pipe 6 moves relative to the connecting hole with friction. This creates a certain gap between the outer circumference of the air guide pipe 6 and the inner side of the connecting hole, ensuring that the air guide pipe 6 can move up and down relative to the tank 2. When the filter cleaning device is equipped with a telescopic motor 22, the specifications of the compressor 5 and the vacuum cleaner 7 need to be limited so that the suction pressure of the vacuum cleaner 7 is greater than the discharge pressure of the compressor 5. In this way, even if there is a gap between the air duct 6 and the connecting hole on the door 18, it will be ensured that all the dust blown off the air conditioning filter 4 in the tank is sucked away by the vacuum cleaner 7 and collected in the dust recovery filter bag 20.

[0044] like Figure 1 As shown, the vacuum cleaner 7 is equipped with a removable dust collection filter bag 20.

[0045] Specifically, in addition to the vacuum cleaner 7, the dust collection structure also includes a suction pipe 8 and a dust collection filter bag 20. There are two suction pipes 8, and the connection points between the suction pipes 8 and the tank 2 are symmetrically arranged. The suction pipes 8 are located at the bottom of the tank 2, and the other end of the suction pipes 8 are connected to the vacuum cleaner 7. The vacuum cleaner 7 uses its own suction force to suck the dust blown off the outside of the filter element in the tank 2 into the vacuum cleaner 7. The dust collection filter bag 20 is installed in the vacuum cleaner 7. When the dust is full, the dust collection filter bag 20 can be replaced directly, and the cleaning operation is very simple.

[0046] In summary, the cleaning device performs the dust removal process on the air filter element 4 to be cleaned as follows: First, confirm the connection status between the air duct 6 and the compressor 5 and the tank 2, and between the suction pipe 8 and the vacuum cleaner 7 and the tank 2. After confirming the connection is complete, place the air filter 4 into the tank 2. Guided by the limiting ring 16, the air filter 4 will contact the top of the ring 10 on the cross bracket 9. Then, pull up the operating button 15 and rotate it 90° according to the direction indicated on the top of the operating button 15. This will lock the operating button 15 into the operating hole, and the four fixing clips 11 at the outer end of the support rod 12 will hold the air filter 4 tightly in place. Then, close the hatch 18 and insert the exhaust pipe 21 into the tank. Inside the body 2, observe the relative position of the air outlet area and the air filter 4 through the transparent acrylic plate, so that the air outlet faces the filter screen of the air filter 4; next, start the rotary motor 3, compressor 5 and vacuum cleaner 7 through the control unit. The compressor 5 sends compressed air into the interior of the air filter, and the vacuum cleaner 7 collects the dust blown down from the tank 2 into the dust recovery filter bag 20. After the cleaning device has been running for a period of time, shut down the three parts through the control unit, rotate the operation button 15 90° in the opposite direction, remove the air filter 4 to check the degree of cleanliness, until the air filter 4 meets the cleaning requirements.

[0047] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
