Referring to fig. 1 and 2, the present application provides a dust suction apparatus 100. The dust suction device 100 may be a cleaning device such as a sweeping robot, a dust collector, or the like. The dust extraction device 100 includes, but is not limited to: device body 10, dirt cup 20, filter member 30 and dust scraper 40.

The apparatus body 10 may be formed with an air inlet 101. The dirt cup 20 may be formed with a receiving chamber 201 and an air outlet 202 and a dust suction opening 203 respectively communicating the receiving chamber 201. The dust suction port 203 is provided with a check valve (not shown) for blocking sucked dust and the like from overflowing from the dust suction port. The dirt cup 20 is movably connected to the apparatus body 10, and the air outlet 202 communicates with the air inlet 101. The dirt cup 20 is movably coupled to the apparatus body 10 to be movable relative to the apparatus body 10 in a predetermined moving direction, and thus can be docked with the apparatus body 10 or undocked from the apparatus body 10 after the relative movement. The filter member 30 is fixedly coupled to the device body 10 and may block the air inlet 101. Airflow enters the air inlet 101 through the dust suction port 203, the accommodating cavity 201 and the air inlet 101, dust, hair, paper dust and other garbage in the airflow is blocked outside the air inlet 101 under the action of the filter element 30 and is trapped in the accommodating cavity 201, and part of the garbage may be wound on the filter element 30 and is accommodated in the accommodating cavity 201.

The dust scraping member 40 may be disposed at the air outlet 202 and contact the outer circumferential surface 301 of the filter member 30. The dust scraping member 40 is detachably connected to the dust cup 20, so that the dust scraping member 40 can slide along with the dust cup 20 along a preset moving direction relative to the apparatus main body 10, and further move relative to the filter member 30 and scrape the outer circumferential surface 301 of the filter member 30. The dust scraping member 40 can scrape the garbage on the outer circumferential surface 301 of the filter member 30, and thus scrape the garbage in the accommodating chamber 201.

Through scraping dirt piece 40 and being fixed in dirt cup 20, scrape dirt piece 40 and can be close to or keep away from device main part 10 along predetermineeing the moving direction along with dirt cup 20 together when dirt cup 20 need empty rubbish and detach device main part 10, and then can remove and scrape the outer peripheral face 301 of filtering piece 30 for filtering piece 30, the in-process that can realize empting the rubbish in dirt cup 20 effectively scrapes the dust on the outer peripheral face 301 of filtering piece 30, rubbish such as miscellaneous bits, realized dismantling dirt cup 20, scrape the ash and empty rubbish in one go, and is convenient and fast.

Referring to fig. 13, in a second situation, the dust scraping plate 41 is rotatably connected to the end of the dust cup 20 with the exhaust port 202 through the rotating shaft 43, the first locking portion 23 is disposed at the end of the dust cup 20 with the exhaust port 202 and away from the rotating shaft 43, the second locking portion 42 is disposed at the end of the dust scraping plate 41 away from the rotating shaft 43, and the first locking portion 23 and the second locking portion 42 are configured to detachably connect the dust scraping element 40 to the dust cup 20 when the dust scraping element 40 is close to or away from the exhaust port 202. The connection structure has good integrity, and the dust scraping plate 41 is rotatably connected with the dust cup 20, so that the dust scraping plate 41 and the dust cup 20 are convenient to detach and mount.

Referring to fig. 9 to 13, the dust scraping plate 41 may include a connecting portion 411 disposed in a circular shape and a wiping portion 412 connected to an inner ring of the connecting portion 411, a through hole 4121 is formed in the wiping portion 412, and the wiping portion 412 is sleeved on the outer circumferential surface 301 through the through hole 4121 and contacts the outer circumferential surface 301 of the filter element 30. The wiping portion 412 is made of an elastic material such as soft rubber, so that when the wiping portion 412 contacts the outer circumferential surface 301, the outer circumferential surface 301 can be wiped without damaging the outer circumferential surface 301.

Alternatively, the through hole 4121 is circular, and the outer circumferential surface 301 has a circular cross section and a diameter corresponding to the through hole 4121, so that the wiping portion 412 is in good contact with the filter member 30, while the wiping portion 412 is rotated relative to the filter member 30, and the wiping portion 412 is still in good contact with the outer circumferential surface 301.

Further, the wiping portion 412 is in the shape of a truncated cone ring, and the cross-sectional area of the wiping portion 412 in the axial direction gradually decreases from the air outlet 201 to the dust suction port 203, so that when the wiping portion 412 scrapes the garbage wound on the outer circumferential surface 301, the wiping portion 412 is in the shape of a cone ring, and the wiping portion 412 can clean the garbage on the outer circumferential surface 301, and the garbage does not stack to the connection portion between the wiping portion 412 and the outer circumferential surface 301, thereby preventing the wiping portion 412 from jamming the filter element 30.

Referring to fig. 1 to 4, during assembly, the fitting structure 321 of the filter element 30 is first fastened to the fastening structure 111 of the main body 11, so as to fixedly connect the filter element 30 to the main body 10; secondly, the second buckling part 42 of the dust scraping piece 40 is matched with the first buckling part 23 of the dust cup 20 in a clamping way, so that the dust scraping piece 40 is detachably connected with the dust cup 20; then, the first guide portion 21 of the dust cup 20 is slidably engaged with the second guide portion 121 of the main body 10, so that the dust cup 20 approaches the positioning portion 12 along the predetermined moving direction until the retaining hole 205 of the dust cup 20 is engaged with the hook portion 1124 of the hook 1121, thereby assembling the dust cup 20 and the main body 10. When the dust cup 20 is close to the positioning portion 12 along the predetermined moving direction, the filter member 40 passes through the through hole 4121.

In cleaning, first, the pressing portion 1125 is pressed to move the hook portion 1124 away from the retaining hole 205, so as to release the fastening connection between the dust cup 20 and the device body 10. Next, the dust cup 20 is far away from the positioning portion 12 along the preset moving direction, and meanwhile, since the wiping portion 412 is in clamping fit with the dust cup 20, the wiping portion 412 scrapes the outer peripheral surface 301 along the preset moving direction as well, and scrapes the garbage on the outer peripheral surface 301 into the accommodating cavity 201. Then, the scraping member 40 is removed from the dust cup 20, and the accommodating chamber 201 is cleaned to remove the garbage and complete the cleaning of the dust cup 20.

In addition, the dust cup 20 is provided with an electric hole (not shown) near the first guide 21 for supplying power to a roller brush provided in the dust cup 20 to clean the filter member 30.

In summary, can slide along with dust cup 20 along predetermineeing the moving direction for device main part 10 through scraping dirt spare 40 for scrape the outer peripheral face 301 that dirt spare 40 can clear up and filter piece 30, so can clear up more conveniently filtering piece 30, and simple and convenient moreover, can dismantle with dust cup 20 through scraping dirt spare 40 and be connected in addition, make things convenient for the clearance, the dismantlement and the maintenance of dirt cup 20 and dust scraping spare 40.

The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
