[0027] Example 1, please refer to Figures 1-9, this embodiment provides an indoor air purifier with an ash removal structure, including: an air purifier body 1; an air inlet hole 2, which is opened on the front of the air purifier body 1; a dust outlet channel 3, which is arranged inside the air purifier body 1; a fan 4, which is fixedly installed inside the air purifier body 1 through a mounting seat; a filter frame 8, which is fixedly connected inside the air purifier body 1. The output end inside the fan 4 extends to the outside and is fixedly connected with a turntable 51. The outer wall of the turntable 51 is fixedly connected with a fixed shaft 52. The outer wall of the mounting seat at the bottom of the fan 4 is rotatably connected with a rotating shaft A 53. The outer wall of the rotating shaft A 53 is fixedly sleeved with a swing rod 54. A chute A 55 is opened on the outer wall of the swing rod 54. The outer wall of the filter frame 8 is fixedly connected with a telescopic rod 56. The other end of the telescopic rod 56 is fixedly connected with a connecting rod A 57. The bottom of the connecting rod A 57 is fixedly connected with a U-shaped block 58. The outer wall of the swing rod 54 is rotatably connected with a slider 59 through a pin shaft. A scraper 520 is arranged inside the filter frame 8. A transmission member for pushing the scraper 520 is assembled outside the filter frame 8. The transmission member includes a toothed plate 510, which is fixedly connected to the upper end of the connecting rod A 57. The outer wall of the filter frame 8 is rotatably connected with a rotating shaft B 511 through a fixed block. The outer wall of the rotating shaft B 511 is fixedly sleeved with a gear 512 and a movable rod A 513. Both ends of the movable rod A 513 are rotatably connected with a connecting rod A 514 through a pin shaft. The other end of the connecting rod A 514 is hinged with a moving plate 515. The inner wall of the air purifier body 1 is fixedly connected with a hydraulic chamber 516. The two ends inside the hydraulic chamber 516 are slidably connected with a hydraulic rod A 517 and a hydraulic rod B 519. The other end of the hydraulic rod A 517 is fixedly connected with the moving plate 515. The other end of the hydraulic rod B 519 is fixedly connected with the scraper 520. A dust removal member for cleaning the air inlet hole 2 is also arranged inside the filter frame 8. The dust removal member includes an elastic telescopic block 521, which is fixedly connected inside the air purifier body 1. The other end of the elastic telescopic block 521 is fixedly connected with a movable plate 522. The outer wall of the movable plate 522 is fixedly connected with a connecting block B 524. The other end of the connecting block B 524 is fixedly connected with a scraping ring 525. An arc-shaped groove 523 is opened on one side of the movable plate 522 close to the scraper 520. One side of the scraper 520 close to the movable plate 522 is also arc-shaped. The scraping ring 525 is slidably connected inside the air inlet hole 2. A through hole is opened at the top of the dust outlet channel 3 and the bottom of the filter frame 8. By opening the through hole, the dust scraped off inside the filter frame 8 can fall into the dust outlet channel 3. A knocking assembly 6 is assembled at the bottom end inside the air purifier body 1. A dust pushing assembly 7 is assembled inside the dust outlet channel 3.

[0028] During use, the air purifier body 1 will suck the indoor air into its interior through the air inlet holes 2 by means of the fan 4, and filter it using the filter frame 8. At the same time, when the fan 4 is started, its output shaft will drive the turntable 51 to rotate. Then, the fixed shaft 52 on the outer wall of the turntable 51 will rotate around the center of the turntable 51. At the same time, the fixed shaft 52 will be inside the chute A55. Since the position of the fixed shaft 52 will move from one side of the turntable 51 to the other side when it rotates, the fixed shaft 52 will drive the swing rod 54 and the rotating shaft A53 to swing left and right. Then, the slider 59 hinged to the upper end of the swing rod 54 will also move left and right reciprocally. At the same time, the slider 59 will slide inside the U-shaped block 58. Then, the connecting rod A57 can be driven by the U-shaped block 58 to move left and right reciprocally. At the same time, the telescopic rod 56 on the side of the connecting rod A57 will extend and contract to ensure the stability of the movement of the connecting rod A57. When the connecting rod A57 moves, it will drive the toothed plate 510 to move. Then, the gear 512 engaged with it will rotate reciprocally accordingly. Then, the rotating shaft B511 will also rotate accordingly. Then, the movable rod A513 on its outer part will also rotate accordingly. When the movable rod A513 rotates, it will drive the moving plate 515 to move through the connecting rods A514 hinged to both ends thereof. When the moving plate 515 moves towards the side of the filter frame 8, it will push the hydraulic rod A517 to slide into the interior of the hydraulic chamber 516. Then, the hydraulic rod B519 at the other end of the hydraulic chamber 516 will drive the scraper 520 to move towards the middle of the filter frame 8, so as to scrape off the dust adhering to the inner wall of the filter frame 8. At the same time, when the scraper 520 moves, one side of it will always be in contact with the movable plate 522. When it moves to the arc-shaped groove 523 opened on the side of the movable plate 522, the elastic telescopic block 521 will push the movable plate 522 towards the scraper 520, so that the side of the scraper 520 is close to the arc-shaped groove 523. When the side of the scraper 520 moves out of the arc-shaped groove 523, it will squeeze the movable plate 522 to reset. During the movement of the movable plate 522, the scraping ring 525 will be driven by the connecting block B524 to slide inside the air inlet hole 2, so as to prevent dust from accumulating inside the air inlet hole 2.

[0029] Embodiment 2. Please refer to Figures 1-9 , on the basis of Embodiment 1, the knocking assembly 6 includes a fixed seat 61. The fixed seat 61 is fixedly connected to the inner bottom end of the air purifier body 1. A rotating rod 62 is rotatably connected to the outer wall of the air purifier body 1. A linkage plate 63 and a mounting rod 64 are fixedly sleeved on the outer part of the rotating rod 62. An elastic pressing plate 65 is fixedly sleeved on the outer part of the rotating shaft A53. The end of the mounting rod 64 far from the rotating rod 62 is fixedly connected to a knocking head 66. A torsion spring 67 is fixedly connected between the linkage plate 63 and the fixed seat 61. The function of the torsion spring 67 is to drive the rotating rod 62 to twist and reset. The function of the knocking assembly 6 is to prevent dust from accumulating inside the dust outlet channel 3.

[0030] During use, when the swing rod 54 rotates, it drives the rotation of the rotating shaft A53. When the rotating shaft A53 rotates, it drives the rotation of the elastic pressing plate 65 outside it. When it rotates clockwise, the elastic pressing plate 65 squeezes the linkage plate 63, thereby driving the rotation of the rotating rod 62 and applying a torsional force to the torsion spring 67. When the elastic pressing plate 65 rotates to the point where it disengages from the linkage plate 63, under the action of the torsion spring 67, the rotating rod 62 and the mounting rod 64 will quickly reset. Then, the mounting rod 64 and the knocking head 66 can knock on the dust outlet channel 3 to prevent the dust scraped into the dust outlet channel 3 from adhering to its inner wall. When the elastic pressing plate 65 rotates counterclockwise and contacts the linkage plate 63, at this time, the knocking head 66 has already adhered to the outer wall of the dust outlet channel 3, so it cannot push the linkage plate 63 and the rotating rod 62 to rotate, and then it will contract, thus not affecting the rotation of the rotating shaft A53.

[0031] Embodiment 3. Please refer to Figures 1-9 , on the basis of Embodiment 1, the dust pushing assembly 7 includes an L-shaped block 71. A dust pushing plate 72 is rotatably connected to the inner side of the L-shaped block 71. An active rod B73 is hinged to the outer wall of the dust pushing plate 72. The other end of the active rod B73 is hinged to a connecting rod B74. The other end of the connecting rod B74 is hinged to the mounting rod 64. A mounting block 75 is fixedly sleeved on the outer wall of the active rod B73. A spring B76 is fixedly connected between the mounting block 75 and the outer wall of the dust outlet channel 3. The active rod B73, the connecting rod B74, the mounting block 75, and the spring B76 are all provided in three.

[0032] During use, when the mounting rod 64 approaches the dust outlet channel 3, it can push the active rod B73 to move outward of the dust outlet channel 3 through the connecting rod B74 hinged at the bottom. When the active rod B73 moves a short distance forward, it will rotate the dust pushing plate 72 and make it approach the L-shaped block 71. When one end of the dust pushing plate 72 rotates to fit the inner wall of the dust outlet channel 3, it can push the dust inside the dust outlet channel 3 out. When the mounting rod 64 moves away from the dust outlet channel 3, it will pull the active rod B73 to reset through the connecting rod B74. When the active rod B73 resets, it will first pull the dust pushing plate 72 to rotate toward the active rod B73 side. When it can no longer rotate, it will then pull the L-shaped block 71 to move inside the dust outlet channel 3. Thus, it can be ensured that when not pushing the dust, the dust pushing plate 72 is in an upwardly lifted state to prevent it from obstructing the falling dust.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
