Description

TECHNICAL FIELD

The present invention relates to the technical field of appliances, and in particular to an inverted cone separation device with double dust-collecting cups and cleaner comprising the same.

BACKGROUND

Cleaners can be divided into vertical, horizontal, and portable types according to their structure. The working principle of the cleaner is to drive the blades by means of a motor to rotate at a high speed, in such a manner that negative air pressure can be generated in the sealed housing, to absorb dust.
At present, more and more families choose horizontal cleaners as cleaning tools. Horizontal cleaners are mainly composed of floor brushes, connecting ducts, a dust collector, a case, and a motor assembly. The dust collectors include dust-collecting cups and separators. The motor assembly has a motor air inlet and a motor air outlet. The motor assembly is used to generate a suction force that draws dust on the ground and surrounding air into the dust chamber of the dust collector via the air inlet of the cleaner. The air and dust are separated by the separator, and the dust falls into the dust-collecting cup. The clean air enters the motor air inlet of the motor assembly from the dust chamber through the separator and is discharged from the air outlet of the cleaner through the motor air outlet.
The filtering system of cleaners in the prior art includes tornado system, single cone filter, and dust bag filter, and the number of filtering layers is small, so that large-particle garbage and fine dust are always mixed together and cannot be separated. Large-particle garbage is entangled and blocked in the dust-collecting cup, and the separation effect is not outstanding enough.

Garbage and sewage mixed together may be introduced into the first dust-collecting cup (31) first. Then, the mixed garbage and sewage may be rotated at a high speed in the first dust-collecting cup (31).
