The connection between the first passage 2111 and the second passage 2112 is arranged so that garbage can enter the body 14 through the connecting column 153, the first passage 2111 and the second passage 2112 in sequence. A cavity 2121 is formed in the accommodating section 212, the cavity 2121 is cylindrical, and a plurality of air holes 2122 are spaced on a side wall of the cavity 2121. The end of the receiving section 212 away from the separating section 211 is further opened with an opening 2123, and the opening 2123 connects the cavity 2121 and the external space, so that the filter element 22 can enter and exit the cavity 2121 through the opening 2123.

The filter element 22 is accommodated in the cavity 2121, and the filter element 22 is disposed in a circular truncated cone shape. It will be appreciated that the cartridge 22 includes a top cover 221, a bottom cover 222, and a plurality of filter plates 223 connected between the top cover 221 and the bottom cover 222. Wherein the top cover 221 has a diameter smaller than the bottom cover 222. The bottom cover 222 is detachably connected to the inner wall of the cavity 2121, and a positioning post 2221 protrudes from the bottom cover 222 at a position corresponding to the connection position 1330, the positioning post 2221 can be connected to the connection position 1330 in a concave-convex manner for stably connecting the filter assembly 20 to the body 14, or the positioning post 2221 is used for holding, so that a user can draw or extend the filter element 22 into or out of the cavity 2121 through the positioning post 2221. Each filter plate 223 is made of filter cotton and/or filter mesh.

It should be noted that, the filter element 22 is configured to enable a plurality of filter plates 223 to be sequentially and annularly connected between the top cover 221 and the bottom cover 222 to form a plurality of filter layers, so as to increase a contact area between the filter element 22 and dust, and to facilitate achieving a rapid and efficient filtering effect. And because the filter element 22 is separably connected with the separating piece 21, if the filter element 22 needs to be replaced, the body 14 and the handheld shell 10a are separated, and the filter element 22 needing to be replaced is pulled away from the separating piece 21, so that the operation is simple and rapid, and time and labor are saved.

The dust collection and filtration process of the filter assembly 20 is specifically as follows: after a plurality of wastes (including dust wastes, blocky wastes and the like) enter the filter assembly 20 under the action of suction force, the wastes firstly enter the body 14 through the separation section 211 in the separation member 21, then under the continuous action of the suction force, dust with small volume can enter the cavity 2121 through the air holes 2122 and be adsorbed on the filter element 22, and other wastes with large volume are separated from the separation member 21, so that the effect of filtering the wastes with different sizes in a segmented manner is achieved. Moreover, because the great other rubbish of volume is blockked outside separator 21, makes the great other rubbish of volume can't contact filter core 22, so can reduce and block up filter core 22, reduce the filter area's of filter core 22 condition because of the great rubbish of volume contacts with filter core 22, make filter core 22 can adsorb more dust more high-efficiently, reach better adsorption effect to reduce the probability that the dust is piled up in body 14.
