Specifically, the filter element 223 includes a frame body 2231 and a filter cloth (not shown), wherein an upper end of the frame body 2231 is provided with an arched handle 22311, and the filter cloth surrounds the frame body 2231 along a circumferential direction of the frame body 2231.

It can be appreciated that the upper end of the housing 2231 is provided with the arched carrying portion 22311 so that the housing 2231 can be easily removed, thereby facilitating the replacement of the filter cloth around the circumference of the housing 2231, and thus the dust collector 100 according to the embodiment of the present invention has advantages of easy disassembly and assembly and easy cleaning.

In some embodiments, as shown in fig. 9, the filter 2 further includes an extension pipe 23, the extension pipe 23 is disposed at an end of the filter housing 22 facing away from the air guiding pipe 21 (e.g., an upper end of the filter housing 22 in fig. 9), at least a portion of the extension pipe 23 extends out of the dirt cup 3, a portion of the filter element 223 is disposed in the filter housing 22, and another portion of the filter element 223 is disposed in the extension pipe 23.

It will be appreciated that a portion of the filter element 223 is disposed within the extension pipe 23, thereby increasing the size of the filter element 223 in the axial direction of the filter 2, that is, the size of the filter element 223 through which the dirt-containing air flow passes in the axial direction of the filter 2 is increased, thereby enhancing the filtering effect of the filter 2 on the dirt-containing air flow.

Furthermore, the extension pipe 23 is partially protruded out of the dust cup 3 to facilitate the detachment and attachment of the extension pipe 23.

In some embodiments, as shown in fig. 8-10, the fan assembly 1 is connected to the filter 2 and removably connected to the bowl 31, and the suction port of the fan assembly 1 is in communication with the filtered air outlet 221.

It will be appreciated that the fan assembly 1 is provided at the upper end of the filter 2, and that, when the dust collector 100 is in operation, the fan assembly 1 is activated to generate a negative pressure at the suction port, thereby sucking the air flow in the filtered air outlet 221. Because the fan assembly 1 is detachably connected with the cup body 31, when the cup body 31 needs to be cleaned, the cup body 31 can be detached separately, so that the dust collector 100 of the embodiment of the invention can separate the fan assembly 1 from the cup body 31, thereby improving the flexibility of cleaning dirt in the dust collector 100 of the embodiment of the invention and facilitating the daily cleaning of the dust collector 100 of the embodiment of the invention by a user, and therefore, the dust collector 100 of the embodiment of the invention has the advantage of good practicability.

Referring to fig. 1, the cleaning apparatus according to the embodiment of the present invention includes a dust container 100, a suction rod 200, and a cleaning head 300. The dust collector 100 is the dust collector 100 of any of the above embodiments; further, as shown in fig. 1, the cleaning device of the embodiment of the present invention further includes a latch connected to the dust suction rod 200 and movable between a first position and a second position relative to the dust suction rod 200, specifically, the first position is far away from the central axis of the dust suction rod 200 relative to the second position, that is, the second position is located inside the first position in the radial direction of the dust suction rod 200. Specifically, as shown in fig. 1, the upper end of the suction rod 200 is connected to the lower end of the filter 2, and the lower end of the suction rod 200 is connected to the upper end of the cleaner head 300, thereby making the cleaning apparatus more reasonable. The cleaning device provided by the embodiment of the invention has the advantages of simple structure, low cost, good cleaning effect and the like.
