[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] See also Figures 1 to 10 As shown, an air purification device based on a hanging structure includes a self-cleaning filter device installed at the air outlet end of the air purification device 1, and the self-cleaning filter device includes an airflow control rail 2, a self-rotating cleaning mounting frame 3, a limiting filter layer 4 and a dust collection bin 5; the airflow control rail 2 is installed inside the air purification device 1, the air inlet end of the airflow control rail 2 is connected to the air outlet end of the air purification device 1, and the airflow control rail 2 is used to control the airflow; the self-rotating cleaning mounting frame 3 is provided with a plurality of and is evenly installed at the air outlet end of the airflow control rail 2; the limiting filter layer 4 is provided with a plurality of and is evenly installed inside the self-rotating cleaning mounting frame 3, and the limiting filter layer 4 is used to filter the air; the dust collection bin 5 is provided with a plurality of and is evenly installed at the bottom of the self-rotating cleaning mounting frame 3, and the dust collection bin 5 is used to collect cleaned dust.

[0039] The air purification device 1 is responsible for purifying outdoor air and sending the treated clean air into the airflow control track 2. As a bridge between the air purification device 1 and the self-rotating cleaning mounting frame 3, the airflow control track 2 not only ensures the smooth flow of airflow, but also intelligently controls the flow and direction of airflow through its internal structure design. According to the change of gas flow, the airflow control track 2 can dynamically adjust the range of gas flow, and this feature is crucial to maintaining the stability of the rotation of the self-rotating cleaning mounting frame 3. The self-rotating cleaning mounting frame 3 is evenly distributed at the air outlet end of the airflow control track 2, and each mounting frame is equipped with multiple limiting filter layers 4. When air passes through the self-rotating cleaning mounting frame 3, the self-rotating cleaning mounting frame 3 will automatically rotate. This design not only promotes the uniform distribution of air, but also realizes the automatic cleaning of the limiting filter layer 4. As a key component for filtering air, the limiting filter layer 4 will continuously accumulate dust on its surface. However, due to the rotation of the self-rotating cleaning mounting frame 3, the dust will be effectively peeled off from the outer wall of the filter layer and then fall into the dust collection bin 5 below. The dust collection bin 5 is located at the bottom of the self-rotating cleaning mounting frame 3 and is responsible for collecting the dust cleaned from the limiting filter layer 4. This design avoids the problem of the filter screen in traditional air purification equipment being blocked due to long-term use, and also greatly simplifies the dust cleaning process. The staff only needs to clean the dust collection bin 5 regularly to ensure the continuous and efficient operation of the equipment without disassembling the entire equipment.

[0040] The self-cleaning filter device not only improves air purification efficiency, but also significantly reduces maintenance costs and time. Since there is no need to frequently replace the filter and the dust cleaning process is simple and quick, the device can maintain high stability and reliability in long-term use.

[0041] See also Figures 1 to 4 As shown, the air inlet 21 of the air flow control rail 2 is connected to the air outlet end of the air purification device 1, and a plurality of air outlet holes 22 are arranged inside the air flow control rail 2. The air outlet holes 22 are all used to limit the installation of the self-rotating cleaning mounting frame 3, and an air flow blocking device 23 is also installed inside the air flow control rail 2.

[0042] The airflow control rail 2 is not only a connecting bridge between the air purification device 1 and the self-rotating cleaning mounting frame 3, but also responsible for intelligently controlling the flow and direction of the airflow to ensure the smooth operation of the entire system. The air inlet 21 of the airflow control rail 2 is closely connected to the air outlet end of the air purification device 1, so that the clean air treated by the air purification device 1 can smoothly enter the airflow control rail 2. Inside the airflow control rail 2, a plurality of air outlets 22 are designed, and each air outlet 22 is limitedly installed with a self-rotating cleaning mounting frame 3. An airflow obstruction device 23 is also installed inside the airflow control rail 2. The airflow obstruction device 23 can dynamically adjust the air outlet area according to the flow rate of the gas. When the air flow increases, the airflow obstruction device 23 will reduce the obstruction accordingly, so that more gas can flow out and enter more self-rotating cleaning mounting frames 3. On the contrary, when the air flow decreases, the airflow obstruction device 23 will increase the obstruction to ensure that the gas can flow to a smaller number of self-rotating cleaning mounting frames 3, thereby maintaining its rotation stability.

[0043] Since the rotation of the self-rotating cleaning mounting frame 3 depends on the promotion of airflow, stable airflow input is essential for its normal operation. The airflow control rail 2 ensures that the self-rotating cleaning mounting frame 3 can maintain stable rotation under different airflow rates by accurately adjusting the air outlet area, thereby achieving continuous automatic cleaning of the limited filter layer 4.

[0044] See also Figures 4 to 6 As shown, the airflow blocking device 23 includes a bidirectional ball screw slide 231 installed on the side of the airflow control rail 2, and the movable ends of the bidirectional ball screw slide 231 are installed with sliding adjustment blocks 232, and an elastic shielding layer 233 is installed on the sliding adjustment block 232. The end of the elastic shielding layer 233 away from the sliding adjustment block 232 is connected to the airflow control rail 2, and the airflow blocking device 23 also includes an infrared detector installed inside the airflow control rail 2, and the infrared detector is used to detect the working state of the self-rotating cleaning mounting frame 3.

[0045] The bidirectional ball screw slide 231 is the core driving component of the airflow blocking device 23. The position of the sliding adjustment block 232 is accurately adjusted by the bidirectional ball screw slide 231, and an elastic shielding layer 233 is installed on the sliding adjustment block 232. The elastic shielding layer 233 is a flexible and elastic material that can fit closely to the inner wall of the airflow control track 2. When the sliding adjustment block 232 moves under the drive of the bidirectional ball screw slide 231, the elastic shielding layer 233 will also move accordingly, thereby changing the area of ​​the air outlet 22 of the airflow control track 2 covered by it. In this way, by adjusting the position of the sliding adjustment block 232, the size of the air outlet area can be dynamically controlled. The infrared detector is installed inside the airflow control track 2 for real-time monitoring of the working state of the self-rotating cleaning mounting frame 3. When the self-rotating cleaning mounting frame 3 rotates unstably or stops rotating, the infrared detector will immediately capture this change and feed back the signal to the control system. After receiving the signal from the infrared detector, the control system will determine whether the self-rotating cleaning mounting frame 3 needs to adjust the airflow input to maintain stable rotation according to the preset algorithm and logic. If adjustment is required, the control system will send a control signal to the bidirectional ball screw slide 231 to drive the sliding adjustment block 232 to move, thereby changing the coverage area of ​​the elastic shielding layer 233, thereby adjusting the air outlet area and air flow rate.

[0046] See also Figures 4 to 7 As shown, the self-rotating cleaning mounting frame 3 includes a limiting mounting frame 31 installed at the bottom of the airflow control rail 2, and a plurality of limiting mounting grooves 311 are provided on the limiting mounting frame 31, and the limiting mounting grooves 311 are used to install the limiting filter layer 4. The axial position of the limiting mounting frame 31 is provided with a rotating cleaning mechanism 32, and the rotating cleaning mechanism 32 is used to clean the inner wall of the limiting filter layer 4.

[0047] The limit mounting frame 31 is the basic structure of the self-rotating cleaning mounting frame 3. It is firmly mounted below the air outlet 22 of the airflow control rail 2. The limit mounting frame 31 is provided with a plurality of carefully designed limit mounting grooves 311. The limit mounting grooves 311 ensure that the limit filter layer 4 can be accurately and stably installed in the groove. When the limit filter layer 4 filters the air, its surface is covered with tiny filter holes, which can effectively block impurities such as dust and particulate matter in the air. During the operation of the air purification equipment, the limit filter layer 4 will continue to accumulate dust. If it is not cleaned in time, it will cause the filtration efficiency to decrease and even affect the normal operation of the equipment. In order to solve this problem, the self-rotating cleaning mounting frame 3 adopts a rotating cleaning mechanism 32. The rotating cleaning mechanism 32 is arranged at the axial position of the limit mounting frame 31. When the airflow passes through the self-rotating cleaning mounting frame 3, it will push the rotating cleaning mechanism 32 to rotate. During the rotation of the rotating cleaning mechanism 32, the working end of the rotating cleaning mechanism 32 will contact the inner wall of the limiting filter layer 4, and the dust, particulate matter and other impurities attached to the inner wall of the filter layer will be peeled off by the action of the rotating cleaning mechanism 32. The peeled dust and impurities will be brought into the dust collection bin 5 below with the flow of the airflow, thereby realizing the continuous automatic cleaning of the limiting filter layer 4. This design not only avoids the problem of the filter screen in the traditional air purification equipment being blocked due to long-term use, but also greatly improves the cleaning efficiency and operation stability of the equipment.

[0048] See also Figures 4 to 8 As shown, the rotating cleaning mechanism 32 includes a first airflow fan 321 rotatably mounted on the airflow control rail 2, a self-rotating bracket 322 is mounted on the first airflow fan 321, a plurality of driving inclined rails 3221 are arranged on the self-rotating bracket 322, and a scraping cleaning strip 323 is installed inside the driving inclined rails 3221, and a friction brush 3231 is arranged on the scraping cleaning strip 323.

[0049] The first airflow fan 321 is the power source of the rotating cleaning mechanism 32. When the airflow passes through, it will push the first airflow fan 321 to rotate. The self-rotating bracket 322 is connected to the first airflow fan 321 and rotates with the rotation of the first airflow fan 321. The driving ramp 3221 has a certain inclination angle. When the self-rotating bracket 322 rotates, the driving ramp 3221 will rotate accordingly, and use the centrifugal force generated by its inclination angle to push the scraping and cleaning strip 323 to spread outward. The scraping and cleaning strip 323 is installed inside the driving ramp 3221 and is provided with a friction brush 3231. The friction brush 3231 is made of soft and wear-resistant material to ensure that the limiting filter layer 4 will not be excessively worn during the cleaning process. When the scraping and cleaning strip 323 is spread outward under the action of centrifugal force, the friction brush 3231 will be in close contact with the inner wall of the limiting filter layer 4, and the dust, particulate matter and other impurities attached to the inner wall of the filter layer will be peeled off by the action of scraping and friction. During the diffusion process, the scraping cleaning strip 323 will be pushed by the centrifugal force, making it fit more closely to the inner wall of the limiting filter layer 4. This design not only improves the cleaning effect, but also avoids excessive friction between the friction brush 3231 and the limiting filter layer 4, thereby extending the service life of the limiting filter layer 4. The peeled dust and impurities will be brought into the dust collection bin 5 below with the flow of airflow, and the device realizes continuous and automatic cleaning of the limiting filter layer 4. Continuous and automatic cleaning of the limiting filter layer 4 is realized. This design not only improves the air purification efficiency, but also significantly reduces the maintenance cost and time of the equipment, so that the entire air purification equipment can maintain high stability and reliability during long-term use.

[0050] See also Figure 6 to Figure 7 As shown, the position-limiting filter layer 4 is annular, and the outer wall of the position-limiting filter layer 4 is covered with position-limiting installation strips 41 .

[0051] Since the position-limiting filter layer 4 is annular in design and its outer wall is covered with position-limiting mounting strips 41, the position-limiting filter layer 4 can maintain a stable shape and position when it is acted upon by the airflow and the rotating cleaning mechanism 32. The tight fit between the position-limiting mounting strips 41 and the position-limiting mounting grooves 311 further enhances the stability of the position-limiting filter layer 4 and prevents it from being displaced or deformed during the cleaning process.

[0052] See also Figure 6 and Fig. 9 As shown, the dust collecting bin 5 is provided with a storage chamber inside, the bottom of the dust collecting bin 5 is provided with a discharge port 51, the top of the dust collecting bin 5 is provided with a plurality of limit clips 52, an elastic telescopic rod 54 is slidably installed inside the dust collecting bin 5, a pressing spring 53 is installed between the elastic telescopic rod 54 and the dust collecting bin 5, a rotating blocking block 55 is provided on the elastic telescopic rod 54, and a plurality of elastic scraping strips 551 are provided on the side of the rotating blocking block 55.

[0053] The limit card strip 52 is used to be mounted on the bottom of the self-cleaning mounting frame 3, so as to improve the convenience of disassembly and installation of the dust collection bin 5. As the dust accumulates, the amount of dust in the storage chamber will gradually increase. At this time, the elastic telescopic rod 54, under the action of the pressing spring 53, will maintain a certain downward pressure, so that the rotating blocking block 55 is closely fitted to the discharge port 51 at the bottom of the storage chamber, preventing dust from overflowing from the discharge port 51. When it is necessary to clean the dust, the staff can press the rotating blocking block 55 from the bottom of the dust collection bin 5. During the pressing process, the rotating blocking block 55 will rise and open the discharge port 51, which is convenient for the staff to clean the inside of the dust collection bin 5. The pressing rotating blocking block 55 is rotatably connected with the elastic telescopic rod 54. To ensure the convenience of cleaning, when pressing the rotating blocking block 55, the staff can drive the rotating blocking block 55 to rotate, and the rotating blocking block 55 will cause the elastic scraping strip 551 and the inner wall of the dust collection bin 5 to be scraped off. At this time, the elastic scraper 551 will use its own softness and wear resistance to scrape off the dust attached to the inner wall of the dust collection bin 5, and then drop it into the discharge port 51. By regularly cleaning the dust in the discharge port 51, the staff can ensure the continuous and efficient operation of the dust collection bin 5, thereby avoiding excessive dust accumulation and affecting the overall performance of the equipment. The device realizes efficient collection and convenient cleaning of dust.

[0054] See also Fig. 9 As shown, the self-cleaning filtering device also includes a dust collection device for cleaning the inside of the dust collection bin 5, and the dust collection device includes a docking mounting sleeve 61, and a self-priming drive member is provided inside the docking mounting sleeve 61. The docking mounting sleeve 61 is connected to the suction pipe 62, and a docking top rod 63 is installed at the tail of the docking mounting sleeve 61.

[0055] When the dust collection bin 5 needs to be cleaned, the staff manually pushes the docking installation sleeve 61 to dock with the discharge port 51 at the bottom of the dust collection bin 5 through the docking push rod 63. A self-priming drive is provided inside the docking installation sleeve 61, which rotates under the drive of the airflow generated when the suction pipe 62 is sucked. At the same time, the self-priming drive is also used to dock and push the rotating blocking block 55 to make it rise and open the discharge port 51. The suction pipe 62 is connected to the dust collection equipment, and the strong suction force generated by the dust collection equipment sucks the dust in the dust collection bin 5 into the suction pipe 62 through the discharge port 51, and is finally collected by the dust collection equipment. During the cleaning process, the self-priming drive can drive the rotating blocking block 55 to rotate, so that the elastic scraper 551 and the inner wall of the dust collection bin 5 are scraped off to ensure that the dust is thoroughly cleaned. The device realizes the purification of outdoor air and the efficient collection and convenient cleaning of dust. It effectively avoids the staff from working at high places and improves the safety of maintenance work.

[0056] See also Fig. 9As shown, the self-priming drive member includes a second airflow fan 64 installed inside the docking installation sleeve 61, a docking drive rod 65 is provided at the axial center position of the second airflow fan 64, and an anti-slip layer is provided on the top of the docking drive rod 65.

[0057] When the dust collection bin 5 needs to be cleaned, the staff first manually pushes the docking installation sleeve 61 to dock with the discharge port 51 at the bottom of the dust collection bin 5. The second airflow fan 64 inside the docking installation sleeve 61 will start to rotate under the drive of the airflow generated when the suction pipe 62 is sucked. This rotation not only enhances the suction effect, but also generates a driving force through the docking drive rod 65 at its axial position. The top of the docking drive rod 65 is provided with an anti-skid layer, and this design ensures its stability and reliability when pushing the rotating blocking block 55. While the second airflow fan 64 rotates, the docking drive rod 65 contacts the rotating blocking block 55 through its anti-skid layer and generates a thrust, so that the rotating blocking block 55 rises and opens the discharge port 51. The suction pipe 62 is connected to the dust collection device, and the strong suction generated by the dust collection device acts on the discharge port 51 of the dust collection bin 5 through the suction pipe 62. Under the action of the suction force, the dust in the dust collection bin 5 is sucked into the suction pipe 62 and finally collected by the dust collection device. When the second airflow fan 64 rotates, it will also drive the docking drive rod 65 to rotate. When the docking drive rod 65 rotates, it will drive the rotating blocking block 55 to rotate synchronously, so that the elastic scraping strip 551 and the inner wall of the dust collecting bin 5 are scraped to ensure that the dust is thoroughly cleaned.

[0058] An air purification method based on an air purification device with a hanging structure comprises the following steps:

[0059] S1, the air purification device 1 is responsible for inhaling outdoor air and processing the air through its internal purification mechanism to remove pollutants and impurities therein.

[0060] S2. The treated clean air is then sent to the airflow control track 2, which ensures the smooth flow of the airflow and dynamically adjusts the range of the gas flow according to the change of the gas flow rate.

[0061] S3. After the clean air enters the airflow control rail 2, it is evenly distributed to each self-rotating cleaning mounting frame 3. When the air passes through the self-rotating cleaning mounting frame 3, the self-rotating cleaning mounting frame 3 will automatically rotate. This rotation not only promotes the uniform distribution of air, but also realizes the automatic cleaning of the limiting filter layer 4.

[0062] S4, the limited filter layer 4 will continuously accumulate dust, however, due to the rotation of the self-rotating cleaning mounting frame 3, the dust will be effectively peeled off from the outer wall of the filter layer and then fall into the dust collection bin 5 below.

[0063] S5. As time goes by, dust in the dust collection bin 5 will gradually accumulate. At this time, the dust collection bin 5 needs to be cleaned regularly. The staff cleans the dust collection bin 5 through a dust cleaning and collection device.

[0064] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
