[0022] S3, during the operation of the dust cleaner body, the pulse dust collector on one side of the top end of the machine body is started synchronously, the pulse dust collector generates a high-frequency pulse airflow to impact the surface of the filter cartridge in the machine body, so that the dust particles adsorbed on the filter cartridge are separated from the surface of the filter cartridge, and the separated dust falls into the ash bucket at the bottom end of the machine body under the action of gravity, completing the dust cleaning and dust collection of the filter cartridge.
[0023] S4, after the pulse deduster runs for a period of time, the electric push rod on the ash bucket side is started, the electric push rod is controlled to extend, the output end of the electric push rod drives the sliding rod to slide downward at the bottom end of the inner wall of the ash bucket through the connecting rod, when the sliding rod moves downward, the brush plate on the inner wall of the ash bucket is pulled downward synchronously through the plurality of pull ropes fixedly connected at the top end of the sliding rod, in this process, the brush rods at both ends of the brush plate slide toward the brush plate due to the end away from the brush plate abutting against the inner wall of the ash bucket, and the springs in the brush plate are compressed, the overall length of the brush plate and the brush rod gradually shortens during the downward movement process, so that the hard bristles on one side of the brush plate and the brush rod always adhere to the inner wall of the ash bucket, in this process, the positioning rods at four corners of the inner wall of the ash bucket limit the sliding track of the brush rod to avoid deviation of the brush rod;
[0024] S5, when the electric push rod extends to the maximum stroke and the brush plate moves to the bottom end of the inner wall of the ash bucket, the electric push rod is reversely controlled to retract, the sliding rod is driven to slide upward at the bottom end of the inner wall of the ash bucket through the connecting rod, when the sliding rod moves upward, the pulling force of the pull rope gradually decreases, the compressed springs at both ends of the brush plate restore to the original state, the brush rods are pushed to move away from the brush plate, the overall length of the brush plate and the brush rod is extended, and the brush plate adheres to the inner wall of the ash bucket again, at the same time, the brush plate moves upward under the assistance of the spring force and the gravity of the brush plate, the hard bristles on one side of the brush plate and the brush rod scrape the inner wall of the ash bucket again, and further remove the dust attached to the inner wall of the ash bucket;

[0038] like Figures 1-5 As shown, the present invention provides a dust collector and a dust removal method that facilitates dust removal. The dust collector includes a body 1, with a filter cartridge installed inside the body 1. A fan 3 is installed on one side of the bottom of the body 1, and one side of the fan 3 is connected to one side of the body 1 via a conveying pipe 4. A suction pipe 5 is installed on one side of the body 1. A dust hopper 6 is fixedly connected to the bottom of the body 1. A pulse dust collector 7 is installed on one side of the top of the body 1. A cleaning device 2 for cleaning the inner wall of the dust hopper 6 is installed on one side of the dust collector. When using the dust collector, a flexible hose is connected to one end of the suction pipe 5 to facilitate the extraction of dust-laden airflow. The fan 3 generates a negative pressure airflow to draw the dust-laden airflow into the body 1. The filter cartridge inside the body 1 adsorbs and filters particulate impurities in the airflow. Subsequently, the air is discharged through the conveying pipe 4 to the other end of the fan 3, completing the dust removal process.
[0039] Reference Figures 1-7As shown in this embodiment: the cleaning device 2 includes an electric push rod 21, which is installed on one side of the ash hopper 6. A sliding rod 22 is mounted on the output end of the electric push rod 21 via a connecting rod. The sliding rod 22 slides on the bottom of the inner wall of the ash hopper 6. Positioning rods 23 are fixedly connected to the four corners of the inner wall of the ash hopper 6. Several brush plates 24 are slidably connected to the inner wall of the ash hopper 6. Brush rods 25 are slidably connected to both ends of each brush plate 24. The brush plates 24 and brush rods 25 all face the inner wall of the ash hopper 6. The brush plate 24 is equipped with several stiff bristles. Springs 26 are attached to both ends of the brush plate 24, with each end of the spring 26 fixedly connected to one side of the inner wall of the brush plate 24 and one end of the brush rod 25, respectively. The end of the brush rod 25 away from the brush plate 24 slides between the positioning rod 23 and the inner wall of the ash hopper 6. A pull rope 27 is fixedly connected to one side of the brush plate 24, with the end of the pull rope 27 away from the brush plate 24 fixedly connected to the top of the sliding rod 22. By configuring the brush plate 24, the dust collector can operate electrically during use. The extended push rod 21 drives the sliding rod 22 downwards via the connecting rod. The sliding rod 22 pulls the various ropes 27, causing the brush plate 24 to move downwards along the inner wall of the ash hopper 6. As the brush plate 24 moves downwards, one end of the brush rods 25 at both ends presses against the inner wall of the ash hopper 6 and moves towards the brush plate 24, compressing the spring 26. As the brush plate 24 and brush rods 25 move towards the bottom of the ash hopper 6, the overall length of the brush plate 24 and brush rods 25 shortens. Then, the electric push rod 21 is activated to retract the brush plate 24. The sliding rod 22 moves upward, and the springs 26 compressed at both ends of the brush plate 24 return to their original state, pushing the brush rod 25 to move away, causing the brush plate 24 and brush rod 25 to move upward. Then, the electric push rod 21 is repeatedly controlled to retract, causing the brush plate 24 and brush rod 25 to move up and down. The hard bristles on one side of the brush plate 24 and brush rod 25 scrape the inner wall of the ash hopper 6, sweeping off the dust particles attached to the inner wall of the ash hopper 6, and avoiding dust accumulation inside the ash hopper 6 as much as possible.
[0040] Reference Figures 2-7 As shown in this embodiment: the end of the brush rod 25 away from the brush plate 24 is rotatably connected to a rotating wheel 28. The rotating wheel 28 abuts against one side of the inner wall of the ash hopper 6. When the brush plate 24 moves up and down, the rotating wheel 28 at one end of the brush rod 25 will move on one side of the inner wall of the ash hopper 6. The rotating wheel 28 can further limit the angle between the brush rod 25 and the ash hopper 6, increasing the stability of the brush rod 25 and the brush plate 24 when they move. A stop bar 29 is fixedly connected to the top of the brush rod 25. The top edge of the stop bar 29 is inclined. By setting the stop bar 29, the top of the brush rod 25 can be protected to prevent dust from entering the top of the brush rod 25 and affecting the normal lateral movement of the brush rod 25.
[0041] Reference Figures 2-7As shown in this embodiment: round rods 210 are fixedly connected to both sides of the inner wall of the brush plate 24. The brush rod 25 slides on the outer surface of the round rod 210. When the brush rod 25 moves, it will slide on the outer surface of the round rod 210. The round rod 210 can further limit the angle between the brush rod 25 and the brush plate 24, and prevent the angle between the brush rod 25 and the brush plate 24 from deflecting. Several limiting rods 211 are fixedly connected to the bottom end of the ash hopper 6. The end of the pull rope 27 away from the brush plate 24 moves inside the limiting rod 211. The limiting rod 211 can limit the movement position of the pull rope 27, and prevent the pull rope 27 from getting tangled when it is close to the bottom end of the ash hopper 6. The two ends of the inner wall of the limiting rod 211 are arc-shaped. By setting the two ends of the inner wall of the limiting rod 211 to be arc-shaped, the outer surface of the pull rope 27 is not easily worn when it moves inside the limiting rod 211, thus improving the service life of the pull rope 27.
[0042] Working principle: When using the dust collector, a flexible hose is connected to one end of the extraction pipe 5 to facilitate the extraction of dust-laden airflow. The operating fan 3 generates negative pressure airflow, drawing the dust-laden airflow into the machine body 1. The filter cartridge inside the machine body 1 adsorbs and filters particulate impurities in the airflow. Subsequently, the air is discharged through the conveying pipe 4 to the other end of the fan 3, completing the dust removal of the air. During the operation of the dust collector, the electric push rod 21 can be extended, driving the sliding rod 22 downward through the connecting rod. The sliding rod 22 pulls the various pull ropes 27, causing the brush plate 24 to move downward on the inner wall of the ash hopper 6. During the downward movement of the brush plate 24, one end of the brush rod 25 at both ends abuts against the inner wall of the ash hopper 6, causing the brush plate 24 to move downward. The brush plate 24 and brush rod 25 move towards the bottom of the ash hopper 6 and compress the spring 26. As the brush plate 24 and brush rod 25 move towards the bottom of the ash hopper 6, the overall length of the brush plate 24 and brush rod 25 will shorten. Then, the electric push rod 21 is operated to retract, which drives the slide rod 22 to move upward. The spring 26 compressed at both ends of the brush plate 24 returns to its original state and pushes the brush rod 25 to move away, causing the brush plate 24 and brush rod 25 to move upward. Then, the electric push rod 21 is controlled to retract, which drives the brush plate 24 and brush rod 25 to move up and down. The hard bristles on one side of the brush plate 24 and brush rod 25 scrape the inner wall of the ash hopper 6, sweeping off the dust particles attached to the inner wall of the ash hopper 6, and avoiding the accumulation of dust inside the ash hopper 6 as much as possible.

10. A dust removal method for a dust collector that facilitates dust removal, characterized in that: The dust collector described in any one of claims 1-9, which is easy to clean, includes the following steps: S1. Check the status of each component of the dust collector and confirm that the core components such as the body (1), cleaning device (2), fan (3), and pulse dust collector (7) are not loose or damaged, and that the filter cartridge is not damaged or blocked. Then, connect the adapter hose to one end of the suction pipe (5) on one side of the body (1) to ensure that the hose connection is tight and there is no air leakage. Then check whether the outlet at the bottom of the ash hopper (6) is unobstructed and clean the residual blocky ash at the outlet. Finally, turn on the power supply of the dust collector and confirm that the circuit connection of the electric push rod (21), fan (3), and pulse dust collector (7) is normal and in a startable state. S2. Start the fan (3). The fan (3) generates a negative pressure airflow, which draws the dust-laden airflow into the machine body (1) through the suction pipe (5) and the connected hose. When the dust-laden airflow flows through the filter cartridge in the machine body (1), the filter cartridge adsorbs and filters the dust particles in the airflow. The filtered clean air enters the fan (3) through the delivery pipe (4) and is finally discharged from the other end of the fan (3), thus realizing the basic dust removal operation. S3. During the operation of the main body of the dust collector, the pulse dust collector (7) on the top side of the machine body (1) is started simultaneously. The pulse dust collector (7) generates a high-frequency pulse airflow to impact the surface of the filter cartridge inside the machine body (1), causing the dust particles adsorbed on the filter cartridge to detach from the surface of the filter cartridge. The detached dust falls into the ash hopper (6) at the bottom of the machine body (1) under the action of gravity, thus completing the filter cartridge cleaning and dust collection. S4. After the pulse dust collector (7) has been running for a period of time, start the electric push rod (21) on one side of the ash hopper (6) and control the electric push rod (21) to extend. Its output end drives the slide rod (22) to slide downward at the bottom of the inner wall of the ash hopper (6) through the connecting rod. When the slide rod (22) moves down, it pulls the brush plate (24) on the inner wall of the ash hopper (6) downward through several pull ropes (27) fixedly connected to the top. During this process, the brush rods (25) at both ends of the brush plate (24) are far from the brush plate (24) and abut against the brush. On the inner wall of the ash hopper (6), the brush slides towards the brush plate (24) due to the tilt angle of the inner wall of the ash hopper (6), while compressing the spring (26) inside the brush plate (24). The overall length of the brush plate (24) and the brush rod (25) gradually shortens as they move downwards, ensuring that the hard bristles on one side of the brush plate (24) and the brush rod (25) always adhere to the inner wall of the ash hopper (6). During this process, the positioning rods (23) at the four corners of the inner wall of the ash hopper (6) limit the sliding trajectory of the brush rod (25) to prevent the brush rod (25) from deviating. S5. When the electric push rod (21) extends to its maximum stroke and the brush plate (24) moves to the bottom of the inner wall of the ash hopper (6), the electric push rod (21) is controlled to retract in the opposite direction. The sliding rod (22) is driven to slide upward at the bottom of the inner wall of the ash hopper (6) through the connecting rod. When the sliding rod (22) moves upward, the tension of the pull rope (27) gradually decreases. The springs (26) that were compressed at both ends of the brush plate (24) return to their original state and push the brush rod (25) to move away from the brush plate (24). The overall length of the brush plate (24) and the brush rod (25) is extended and they are in contact with the inner wall of the ash hopper (6) again. At the same time, the brush plate (24) moves upward with the help of the spring force and its own weight. The hard bristles on one side of the brush plate (24) and the brush rod (25) perform a second scraping of the inner wall of the ash hopper (6) to further remove the dust attached to the inner wall. S6. The extension and retraction of the electric push rod (21) are continuously controlled in a cycle, driving the brush plate (24) and brush rod (25) to move up and down repeatedly on the inner wall of the ash hopper (6). During the movement, the wheel (28) at one end of the brush rod (25) rolls on the inner wall of the ash hopper (6), and the positioning rod (23) further restricts the angle of the brush rod (25) to improve the stability of movement. The round rods (210) on both sides of the inner wall of the brush plate (24) adjust the sliding direction of the brush rod (25). The guide rod (25) is used to prevent the brush rod (25) from tilting at an angle when sliding, ensuring that the hard bristles are evenly scraped in all areas of the inner wall of the ash hopper (6). At the same time, the limiting rod (211) at the bottom of the ash hopper (6) constrains the movement trajectory of the pull rope (27) to prevent the pull rope (27) from getting tangled. The arc-shaped structure at both ends of the inner wall of the limiting rod (211) prevents the pull rope (27) from wearing out when it moves, extending the service life of the pull rope (27). Finally, the dust particles attached to the inner wall of the ash hopper (6) are completely swept off. S7. During the cyclic cleaning process of the cleaning device, the dust scraped down in the ash hopper (6) gradually accumulates at the bottom outlet. The dust discharge mechanism at the bottom of the ash hopper (6) is opened periodically to allow the dust to be discharged under gravity. If a slight blockage occurs during the discharge process, the inner wall of the ash hopper (6) can be vibrated by the single up-and-down movement of the cleaning device to assist in the discharge of dust and ensure that no dust accumulates at the outlet. S8. When the dust discharge is smooth and no obvious dust is observed on the inner wall of the ash hopper (6), first turn off the electric push rod (21) of the cleaning device, then turn off the pulse dust collector (7) and the fan (3) in sequence, disconnect the power supply of the dust collector, check whether there is a small amount of dust remaining on the inner wall of the ash hopper (6), if there is any residue, the electric push rod (21) can be manually started once or twice to clean the dust, and at the same time check whether the pull rope (27) moves normally within the limit rod (211) and whether the stop bar (29) at the top of the brush rod (25) is intact. After ensuring that there are no abnormalities in each component, the entire dust cleaning process is completed.
