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.
