Detailed Description

The invention is further explained below with reference to the drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention have been described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

As shown in fig. 1 to 5, the dust collection and filtration device for the garbage bin of the electric sweeper comprises a dust collection fan 2 installed at the top of the garbage bin 1, wherein a built-in filtration mechanism is installed in the garbage bin 1 before an air inlet 21 of the dust collection fan 2, and is used for primarily filtering and dedusting dust in the dust absorption bin, and the built-in filtration mechanism can be implemented by adopting a common filter screen and other structures in the prior art, and is not described herein again; an external filtering mechanism 3 is arranged outside the dustbin 1 and behind the air outlet 22 of the dust collection fan 2.

Referring to fig. 1 and 5, in this embodiment, the external filtering mechanism 3 includes a wind collecting cover 31 covering the periphery of the dust collection fan 2, the wind collecting cover 31 is fixed to the top of the dustbin by bolts, an air outlet 32 is formed in the wind collecting cover 31, and a filter screen 33 is disposed at the air outlet 32. Cover dust absorption fan 2 through air-collecting cover 31, regard the rear as only air exit, both can guarantee that the air discharges again after filtering through filter screen 33, avoids dust to spread everywhere, and handsome in appearance is convenient for arrange moreover.

Referring to fig. 1, 7 and 8, the filter screen 33 is fixedly installed on the filter screen frame 34, a dust shaking mechanism 4 for driving the filter screen frame 34 to vibrate back and forth is arranged between the filter screen frame 34 and the garbage can 1, and a vibration guiding mechanism 5 is arranged between the filter screen frame 34 and the air collecting cover 31.

Referring to fig. 7 and 8 again, in the present embodiment, the dust shaking mechanism 4 includes a support 41 fixedly disposed on the outer side of the trash can 1, a driving motor 42 is mounted on the support 41, and an output shaft of the driving motor 42 is fixedly connected with a cam 43; a lifting rod 44 is arranged on the support 41 in a lifting manner, and a pressing wheel 45 matched with the cam 43 is arranged on the lifting rod 44; the filter screen frame 34 is fixedly provided with a jacking seat 46.
