at this time, under the action of gravity or the reset component 18, the positioning column 13 withdraws from the positioning sleeve 11 until the limiting structure 15 of the air inlet pipe 7 contacts with the limiting lower stop 17, so as to realize withdrawal of the air inlet pipe 7 from the filter component, and simultaneously, the bottom plate 12 of the air inlet pipe 7 is separated from the filter support 19 of the filter component, and the first dust collecting space 10 and the second dust collecting space 14 which are mutually independent originally because the bottom plate 12 is closely contacted with the filter support 19 are directly communicated due to separation of the bottom plate 12 and the filter component.
S4, small particle dust and/or foreign matters in the second dust collecting space 14 directly enter the first dust collecting space 10;
s5, small particle dust and/or foreign matters entering the first dust collecting space 10 are separated from the first dust collecting space 10 from the bottom of the dust cup body 6 together with large particle dust and/or foreign matters of the first dust collecting space 10.
In order to ensure that the first dust collecting space 10 and the second dust collecting space 14 are independent of each other, it is necessary to detach the filter assembly, or to take out the second dust collecting space 14, or to provide a separate cleaning channel for the second dust collecting space 14, as is the case in the prior art. The method of the embodiment of the application does not need to disassemble the dust cup, and does not need to independently set an independent cleaning channel for the second dust collecting space 14, so that the whole process is simple to operate, the cleaning steps of the dust cup are simplified, the abrasion of each part in the dust cup caused by repeated installation and disassembly is relieved, and the possibility of bad dust collection effect of the dust collector and the like caused by the fact that the dust collection is not in place can be reduced.
The present application is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present application are intended to be included in the scope of the present application.
