The carbon layer is located between the debris removal component and the air outlet window. The air inlet pipe and the air outlet window are located at the ends of the shell along its length.

[0003] The air purification equipment in the above solution uses a fixed filter structure. During long-term use, a large amount of dust and impurities easily accumulate on the surface of the outer filter, leading to a decrease in air intake efficiency and a weakening of purification effect. At the same time, it is necessary to stop the machine to clean or replace the filter, which is cumbersome and has high maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide an air purification device with a clean structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air purification device with a cleaning structure, comprising a housing, a base fixedly connected to the bottom of the housing, a bracket installed on the top of the base, multiple outer filter elements arranged in a circular array inside the bracket, an intermediate filter element installed in the center of the bracket, a movable frame installed on one side of the top of the base, a movable plate disposed inside the movable frame, a cleaning brush fixedly connected to the front side of the movable plate, and the cleaning brush being in contact with the outer surface of the outer filter elements.

[0006] Preferably, the movable frame is rotatably connected to a threaded rod, which passes through the movable plate and is threadedly connected to the movable plate. The rotation of the threaded rod drives the movable plate and the cleaning brush to move up and down reciprocally. A temporary storage slot is provided on the top of the base, which is located at the bottom of the movable frame. A support plate is installed on the top of the temporary storage slot.

[0007] Preferably, the top end of the threaded rod passes through the movable frame and is rotatably connected to the movable frame, and a gear is fixedly connected to the top end of the threaded rod, which drives the threaded rod to rotate.

[0008] Preferably, a support frame is fixedly connected to the top of the bracket, and a gear ring is fixedly connected to the outside of the support frame. The gear ring meshes with a gear, so that the support frame drives the gear ring to rotate, thereby driving the gear to rotate.

[0009] Preferably, a circular groove is provided at the center of the top of the base, and a stepper motor is installed inside the circular groove. The output end of the stepper motor is fixedly connected to the bracket, so that the stepper motor can start and drive the bracket to rotate.

[0010] Preferably, a feed pump is installed on one side inside the housing, and a slot is provided on the other side of the top of the housing. A storage box is movably engaged inside the slot. The storage box has an opening at the end facing the feed pump. The input end of the feed pump extends into the temporary storage tank, and the output end of the feed pump extends into the slot and corresponds to the opening at the end of the storage box. Impurities falling into the temporary storage tank are transferred to the storage box for storage by the feed pump.

[0011] Preferably, a fixing plate is installed inside the outer casing, a main air pump is installed on the top of the fixing plate, an air outlet filter is installed on the top of the outer casing, the air outlet filter corresponds to the main air pump, an air inlet filter is installed inside the side wall of the outer casing, and the movable frame is staggered with the air inlet filter.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application enables the threaded rod to drive the moving plate and cleaning brush to move up and down reciprocally. In addition, the width of the cleaning brush is set to be twice or more the length of the outer arc surface of the outer filter element. This allows the cleaning brush to completely pass over the surface of the outer filter element during rotation and up and down movement to remove dust, which is beneficial for self-cleaning of the outer filter element. The cleaning step can be performed during operation without affecting the purification work. Impurities are scraped downward into the temporary storage tank for temporary storage. The impurities in the temporary storage tank are transferred to the storage box by the feed pump at regular intervals, which can increase the storage capacity of impurities and reduce the cleaning frequency. The storage box can be manually pulled out from the base at regular intervals for cleaning, which is convenient for use.

[0014] 2. In this application, a stepper motor drives the bracket to rotate. When the bracket rotates, it drives multiple outer filter elements to rotate, causing the outer filter element with excessive impurities to move away from the position of the air inlet filter. The next clean outer filter element moves to the position of the air inlet filter for filtration, increasing the working time and improving the purification effect. The filtered gas enters the interior of the intermediate filter element and enters the main air pump from the top of the intermediate filter element. Finally, clean air is discharged from the air outlet filter. Attached Figure Description

[0021] 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.

[0022] Example: Figures 1-5As shown, this utility model provides a technical solution for an air purification device with a cleaning structure, including a shell 1, a base 2 fixedly connected to the bottom of the shell 1, a bracket 3 mounted on the top of the base 2, multiple outer filter elements 4 arranged in a circular array inside the bracket 3, an intermediate filter element 5 mounted in the center of the bracket 3, a movable frame 6 mounted on one side of the top of the base 2, a movable plate 8 disposed inside the movable frame 6, a cleaning brush 9 fixedly connected to the front of the movable plate 8, the cleaning brush 9 being in contact with the outer surface of the outer filter elements 4, a threaded rod 7 rotatably connected inside the movable frame 6, the threaded rod 7 passing through the movable plate 8 and threadedly connected to the movable plate 8, the rotation of the threaded rod 7 driving the movable plate 8 and the cleaning brush 9 to move up and down reciprocally. The support frame 3 has a temporary storage slot 10 located at the bottom of the movable frame 6. A support plate 16 is installed on the top of the temporary storage slot 10. The top of the threaded rod 7 passes through the movable frame 6 and is rotatably connected to the movable frame 6. A gear 17 is fixedly connected to the top of the threaded rod 7, which drives the threaded rod 7 to rotate. A support frame 19 is fixedly connected to the top of the support frame 3. A gear ring 18 is fixedly connected to the outside of the support frame 19. The gear ring 18 meshes with the gear 17, causing the support frame 19 to drive the gear ring 18 to rotate, which in turn drives the gear 17 to rotate. A circular groove 14 is opened at the center of the top of the base 2. A stepper motor 15 is installed inside the circular groove 14. The output end of the stepper motor 15 is fixedly connected to the support 3, which starts the stepper motor 15 and drives the support 3 to rotate.

[0023] A material pump 11 is installed inside the outer casing 1 on one side. A slot 12 is opened on the other side of the top of the outer casing 1. A storage box 13 is movably engaged inside the slot 12. The storage box 13 has an opening facing the material pump 11. The input end of the material pump 11 extends into the temporary storage tank 10. The output end of the material pump 11 extends into the slot 12 and corresponds to the opening at the end of the storage box 13. Impurities falling into the temporary storage tank 10 are transferred to the storage box 13 for storage by the material pump 11. A fixing plate 20 is installed inside the outer casing 1. A main air pump 21 is installed on the top of the fixing plate 20. An exhaust filter 22 is installed on the top of the outer casing 1. The exhaust filter 22 corresponds to the main air pump 21. An intake filter 23 is installed inside the side wall of the outer casing 1. The movable frame 6 is staggered with the intake filter 23.

[0024] In operation, the main air pump 21 is activated to draw air from its bottom, drawing in outside air through the intake filter 23. The intake filter 23 performs initial filtration of impurities, allowing the air to enter the outer filter element 4 for secondary filtration. Many dust particles and impurities are trapped on the surface of the outer filter element 4. After a period of use, if the surface of the outer filter element 4 corresponding to the position of the intake filter 23 becomes excessively contaminated, a time relay controls the stepper motor 15 to start, causing the support 3 to rotate. As the support 3 rotates, multiple outer filter elements 4 rotate, causing the outer filter element 4 with excessive impurities to move away from the position of the intake filter 23. The next clean outer filter element 4 moves to the position of the intake filter 23 for filtration, increasing the working time and improving the purification effect. The filtered air then enters the middle filter element 5 and enters the main air pump 21 from the top of the middle filter element 5, finally being discharged clean air from the exhaust filter 22.

[0025] When the outer filter element 4 rotates, it passes inside the moving frame 6. At the same time, the bracket 3 rotates, causing the support frame 19 to rotate. When the support frame 19 rotates, it causes the gear ring 18 to rotate, and then the gear 17 to rotate. When the gear 17 rotates, it causes the threaded rod 7 to rotate, thereby causing the threaded rod 7 to move the moving plate 8 and the cleaning brush 9 up and down. In addition, the width of the cleaning brush 9 is set to be twice or more the length of the outer arc surface of the outer filter element 4, so that the cleaning brush 9 can completely pass over the surface of the outer filter element 4 during the rotation of the outer filter element 4 to remove dust. This is beneficial for the self-cleaning of the outer filter element 4. The cleaning step can be performed during operation without affecting the purification work. The impurities are scraped downward into the temporary storage tank 10 for temporary storage. The impurities in the temporary storage tank 10 are transferred to the storage box 13 by the feed pump 11 starting at regular intervals. This can increase the storage capacity of impurities and reduce the cleaning frequency. The storage box 13 is manually pulled out from the base 2 at regular intervals for cleaning, making it convenient to use.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
