Abstract
Description
Technical Field
[0001] This invention relates to the field of air purifier technology, specifically to an air purifier with an automatic filter cleaning function and its usage method. Background Technology
[0002] An air purifier is an electrical appliance that uses technologies such as physical filtration, chemical adsorption, or photocatalytic decomposition to remove pollutants such as particulate matter, harmful gases, odors, and microorganisms from indoor or enclosed spaces, thereby improving air quality and protecting respiratory health.
[0003] When air purifiers are in use, they typically use filters to filter pollutants in the air. However, over a long period of use, pollutants gradually accumulate in the pores of the filter material, increasing airflow resistance and causing the purifier to experience reduced airflow and slower purification speed. As a result, it cannot effectively improve indoor air quality. Therefore, it is necessary to clean, maintain, or replace the filter regularly to maintain purification efficiency and avoid secondary pollution.
[0004] Existing methods for cleaning filters typically involve removing the filter directly and using tools such as brushes to remove surface dust. However, these methods not only fail to thoroughly remove pollutants accumulated in the pores but also require stopping the air purifier and collecting the pollutants in a container to prevent secondary pollution of the surrounding environment, resulting in poor filter cleaning effectiveness. Therefore, we now offer an air purifier with automatic filter cleaning and its usage method, which eliminates the drawbacks of existing devices. Summary of the Invention

[0039] 3. Through the cooperation of the cleaning mechanism and the rotating mechanism, the power supply can be automatically cut off while the flip plate is flipped. Furthermore, through the cooperation of the filter body and the fan assembly, the air can continue to be filtered and purified.

[0053] The cleaning mechanism includes: a connecting seat 203 disposed inside the filter body 10; multiple exhaust nozzles 2019 are horizontally and equidistantly installed on the bottom of the inner wall of the connecting seat 203; a fixing cylinder 2018 is fixedly connected to the end of the connecting seat 203 away from the flip plate 6; the fixing cylinder 2018 is fixedly connected to the purifier body 1; the fixing cylinder 2018 contacts the outer wall of an end cap 13; a first support plate 2017 is fixedly connected inside the fixing cylinder 2018; an air pump 2016 is installed at the top of the first support plate 2017; the air pump 2016... The output end of the air pump 2016 is fixedly connected to a first air supply hose. The first air supply hose is located below the first support plate 2017. The first air supply hose passes through the fixed cylinder 2018 to the inside of the connecting seat 203. The connecting seat 203 has an air supply groove at the port of the first air supply hose that connects to the ends of multiple exhaust nozzles 2019. The input end of the air pump 2016 is fixedly connected to a second air supply hose. The second air supply hose is located above the first support plate 2017. The second air supply hose passes through the fixed cylinder 2018 to the inner cavity of an end cap 13.
[0054] The cleaning mechanism also includes a drive assembly disposed on the main body 1 of the purifier;
[0055] The drive assembly includes: a support base 2020 fixedly connected to the bottom of the inner wall of the purifier body 1; a drive motor 2013 is installed on the support base 2020; a transmission turntable 2012 is provided at the end of the support base 2020 away from the flip plate 6; a second transmission rod 2015 is fixedly connected to one end of the transmission turntable 2012; the second transmission rod 2015 is driven by the output end of the drive motor 2013; and the second transmission rod 2015 is rotatably connected to the support base 2020.
[0056] The end cap 13 is provided with a rotating assembly for driving the end cap 13 to rotate;
[0057] The flip plate 6 is equipped with a start-stop assembly for controlling the start and stop of the drive motor 2013 and the air pump 2016.
[0058] The main body 1 of the purifier is equipped with a rotating mechanism for driving the filter cylinder 14 to rotate;
[0059] In this embodiment, it should be noted that: a wind speed sensor for real-time detection of airflow speed is installed at the top of the connector 203, and the wind speed sensor is electrically connected to the control terminal through a wire.
[0060] When in use, the fan assembly 7 is started to draw in outside air through the air inlet 4 and deliver the drawn air into the inner cavity of the purifier body 1. At this time, the air can be guided into the inner cavity of the filter body 10 through the cooperation of the fixed baffle 11 and the partition plate 12. In this way, the pollutants in the air can be filtered through the filter body 10, and then the filtered air is discharged to the outside through an exhaust port 5.
[0061] During this process, the airflow rate of the purified air can be detected in real time by the wind speed sensor, and the detected data is transmitted to the control terminal. The control terminal analyzes the data. During this process, the cleaning mechanism can drive the end cap 13 to drive the filter body 10 to rotate, so that the air can be stably filtered through the rotating filter body 10.
[0062] When pollutants accumulate and clog most of the pores on the filter element body 10, causing the airflow velocity to drop to a specified value, the cleaning mechanism can flush away the pollutants attached to the filter element body 10, thereby effectively preventing the pollutants from continuing to accumulate in the pores at different locations of the filter element body 10. The removed pollutants can be guided to the inner cavity of the filter screen cylinder 14 through the exhaust port 8 and the third support plate 9, and the pollutants are filtered and collected by the filter screen cylinder 14. At this time, the filtered air can be discharged to the outside through another exhaust port 5, thereby achieving the purpose of convenient collection of pollutants. At the same time, the filter screen cylinder 14 can be driven to rotate by the cooperation of the cleaning mechanism and the rotating mechanism, thereby effectively preventing the accumulation of pollutants in local locations of the filter screen cylinder 14 when the local air is transported too fast. When the control terminal detects that the airflow velocity rises to a specified value through the wind speed sensor, the cleaning mechanism stops the extraction of part of the purified air, so that the air can continue to be purified through the filter element body 10.
[0063] When pollutants need to be treated, the cleaning mechanism can automatically stop the power supply when the locking and fixing of the flip plate 6 is released and the flip plate 6 is flipped. At the same time, the air filtration and purification operation can continue through the cooperation of the fan assembly 7 and the filter body 10. Then, the filter screen cylinder 14 can be replaced without stopping the machine through the rotation mechanism. When the filter body 10 needs to be replaced, the above operation is repeated and the fan assembly 7 is stopped. Then, one end cover 13 is pulled to move the other end cover 13 horizontally through the filter body 10. At this time, the filter body 10 can be easily replaced through the cleaning mechanism.

At the same time, the other first gear ring 205, driven by the meshing of the other first gear 201, drives the other end cover 13 to rotate synchronously through the transmission sleeve 202 and the docking block 208. At this time, the filter element body 10 rotates under the drive of the two end covers 13. At the same time, through the mutual cooperation of the partition plate 12 and the connecting seat 203, the inner cavity of the upper and lower ends of the filter element body 10 can be separated, so as to achieve stable air filtration.
[0076] When pollutants accumulate and clog most of the pores on the filter element body 10, causing the airflow rate to drop to a specified value, the air pump 2016 is activated to extract some of the purified air from the inner cavity of the filter element body 10 through the second air delivery hose. At the same time, through the cooperation of the first air delivery hose and the air delivery groove, the extracted air can be delivered to the inner cavity of multiple exhaust nozzles 2019. In this way, the pollutants attached to the filter element body 10 can be flushed and removed through the multiple exhaust nozzles 2019, effectively preventing the pollutants from continuing to accumulate in the pores at different locations of the filter element body 10. At this time, the removed pollutants can be guided to the inner cavity of the filter screen cylinder 14 through the exhaust port 8 and the third support plate 9. At the same time, the air pollutants can be filtered and collected through the filter screen cylinder 14. Then, the filtered air can be discharged to the outside through another exhaust port 5, thereby achieving the purpose of convenient collection of pollutants.
[0077] Meanwhile, the bevel ring 301, driven by the second transmission rod 2015, drives the bevel gear 306 to rotate through meshing. At this time, the connecting turntable 304, driven by the bevel gear 306 through the transmission shaft 307, drives the connecting plate 302, guide plate 308, and limiting slide plate 309 to rotate synchronously. At this time, the filter screen cylinder 14 rotates under the drive of the limiting slide plate 309. This can effectively prevent pollutants from accumulating in local positions of the filter screen cylinder 14 when the local air is transported too fast. When the control terminal detects that the air flow rate rises to a specified value through the wind speed sensor, it stops the air pump 2016 from extracting part of the purified air, so that the air can continue to be purified through the filter body 10.
[0078] When pollutants need to be treated, the knurled bolt 2021 is rotated to separate from the third support plate 9, thereby releasing the locking and fixing of the flip plate 6. Then, the flip plate 6 is pulled to flip to the outside of one end of the purifier body 1. At this time, the first conductive sheet 2022 is separated from the outer wall of the second conductive sheet 2023 under the action of the flip plate 6, thereby automatically stopping the power supply to the drive motor 2013 and the air pump 2016, so that the drive motor 2013 and the air pump 2016 can stop running synchronously. And through the cooperation of the fan assembly 7 and the filter body 10, the air can continue to be filtered and purified.
[0079] Then, manually rotate the connecting turntable 304 to rotate one end of the limiting slide plate 309 to the end closer to the flip plate 6. Then, pull the filter cylinder 14 to move the limiting slide plate 309 so that the guide plate 308 slides along the inner wall of the connecting turntable 304. This allows the limiting slide plate 309 to separate from the outer wall of one end of the connecting plate 302. At the same time, the second positioning block 303, under the pressure of the outer wall of the guide plate 308, pushes the second sliding baffle 3011 to slide along the inner wall of the connecting turntable 304. At this time, the second sliding baffle 3011 retracts by moving and pressing the second spring 3010. When the guide plate 308 is completely separated from the outer wall of the second positioning block 303, the second spring 3010 pushes the second sliding baffle 3011 to reset by rebound. Then, the above operation is reversed, so as to achieve the purpose of replacing the filter cylinder 14 without stopping the machine, thereby meeting the needs of stable operation of the equipment in high-load purification scenarios.
[0080] When the filter element body 10 needs to be replaced, repeat the above operation and control the fan assembly 7 to stop running. Then, pull one end cover 13 to drive the other end cover 13 to move horizontally through the filter element body 10. At this time, the docking block 208 slides along the inner wall of the transmission collar 202 under the drive of the end cover 13. At the same time, the first positioning block 2014 pushes the first sliding baffle 204 to slide along the inner wall of the transmission collar 202 under the pressure of the outer wall of the end cover 13. At this time, the first sliding baffle 204 retracts by moving and pressing the first spring 209. When the end cover 13 and the first positioning block 2014 are completely separated, the first spring 209 pushes the first sliding baffle 204 to reset by rebound. Then, the above operation is reversed to achieve the purpose of convenient replacement of the filter element body 10.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
