[0025] The specific embodiments of the utility model will be further described in detail below in combination with the drawings.

[0026] Embodiment: as Figures 1-6 The utility model discloses a specific embodiment of dust collector with ash scraping device, it includes: the body 100, the dust cup 200 with the body 100 is connected and has the filter cover 240 in, the motor 300 located in the body 100 and located the dust cup 200 downstream, set up in the body 100 and can the ash scraping device 400 of ash scraping device 400 surface to the filter cover 240, and the power supply 500 located in the handle body 160 another end and to the motor 300 power supply.

[0027] The body 100 includes the air inlet pipe body 120, the motor body 140 for containing the motor 300 and being connected with the dust cup 200, and the handle body 160 for supporting the motor body 140 at one end. The extension direction of the air inlet pipe body 120 is parallel to the central axis direction of the dust cup 200. The extension direction of the handle body 160 intersects with the extension direction of the air inlet pipe body 120 at an obtuse angle, and is used for supporting the dust cup 200. A pair of handle through holes 144 are arranged on both sides of the motor body 140.

[0028] The dust cup 200 is generally hollow cylindrical. This embodiment also includes a filter element 260 detachably located within the filter cover 240 for further filtering the airflow; the center of the filter element 260 is collinear with the center of the dust cup 200. The filter cover 240 is provided with a metal mesh 244. The metal mesh 244 has several mesh openings that allow airflow to pass through.

[0029] Motor 300 is a DC motor, and its center direction is the same as that of dust cup 200. One end of motor 300 is adjacent to air inlet hood 320 of the main body. The other end of air inlet hood 320 is connected to the downstream end of dust cup 200. Air inlet hood 320 is located inside motor body 140 and is fixedly connected.

[0030] The dust removal device 400 includes a handle portion 420 that is rotatable relative to the body 100 and easy for the user to operate, a connecting portion 460 driven by the handle portion 420, and a dust removal portion 480 that reciprocates relative to the filter cover 240. The handle portion 420 is U-shaped, with a hollow portion housing the motor body 140, and both ends being handle shaft ends 424 that can be inserted into handle through holes 144. A rectangular through groove is provided in the handle shaft end 424. The rotational movement of the handle portion 420 includes movement along a first direction, while the dust removal portion 480 moves along a second direction, wherein the first direction and the second direction are opposite to each other. This embodiment also includes a swing portion 440 connected to the handle portion 420 and having a swing shaft 444 and a groove 448. The swing shaft 444 is coaxially arranged with the handle shaft end and matches the shape of the rectangular through groove for a snap-fit ​​engagement. The connecting part 460 includes a connecting protrusion 464 that can reciprocate within the groove 448, and a connecting rod 468 connected at one end to the connecting protrusion 464 and at the other end to the dust scraper 480. The dust scraper 480 includes a hollow, annular, and soft dust scraper ring 485 fitted onto the filter cover 240. The dust scraper ring 485 has an interference fit with the metal mesh 244 to remove dust from the surface of the metal mesh 244.

[0031] During operation, the dust-laden airflow enters the unit 120 through the inlet duct and undergoes cyclone separation in the dust cup 200. Large dust particles are retained inside and at the end of the dust cup 200, while fine dust particles pass through the mesh of the metal mesh 244, are filtered again by the filter element 260, and then enter the motor 300 before being discharged to the outside. When the metal mesh 244 becomes too dusty, the user can rotate the handle 420 towards the user, causing the swing part 440 to move linearly away from the user, which in turn moves the connecting rod 468. Then, the scraper ring 485 scrapes the surface of the metal mesh 244 to remove surface dust, thereby reducing clogging of the mesh.

[0032] The advantages of this invention are: it is used to scrape the outer surface of the filter cover to prevent the mesh from being blocked and to improve dust removal performance.

[0033] The above are merely preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
