Surface cleaning device with dust cup assembly

Abstract

The invention discloses surface cleaning equipment with a dust cup assembly, the dust cup assembly comprises a cyclone separation chamber and a dust collection chamber, and the cyclone separation chamber is arranged on the outer side of the dust collection chamber and communicates with the dust collection chamber through a dust throwing opening; the dust cup assembly further comprises an air outlet formed in the cyclone separation chamber and a filtering structure arranged at the air outlet, and the filtering structure is rotatably arranged at the air outlet so as to filter air flow before the air flow is discharged from the air outlet. A baffle plate extending in the dust collecting chamber is arranged at the dust throwing opening so as to prevent part of dirt in the dust collecting chamber from being pumped back into the cyclone separation chamber; at least one protrusion protruding towards the direction of the bottom of the dust collection chamber is arranged on the side, facing the bottom of the dust collection chamber, of the baffle. The baffle is arranged at the ash throwing opening, the protrusion is arranged below the baffle, and therefore the hair can be effectively prevented from being pumped back to the cyclone separation chamber.

Description

technical field [0001] The present invention relates to the technical field of cleaning equipment, in particular to a surface cleaning equipment with a dust cup assembly. Background technique [0002] Cyclone separators are generally divided into two forms, one is an integrated type, that is, the cyclone separation chamber and the dust collection chamber are both arranged in one chamber. The other is a separate type, that is, the cyclone separation chamber and the dust collection chamber are set separately, and the two are connected through the ash throwing port, and the dirt separated from the cyclone separation chamber enters the dust collection chamber through the ash throwing port. [0003] The advantage of using a separate cyclone separator is that the dust can be collected separately without being repeatedly sucked into the cyclone separation chamber. However, due to the frequent occurrence of hair in the process of daily cleaning, the hair is relatively light and can ...

Problems solved by technology

[0003] The advantage of using a separate cyclone separator is that the dust can be collected separately and will not be repeatedly sucked into the cyclone separation chamber. However, hairs often appear in the process of daily cleaning, and the hairs are relatively light, so they are easily drawn back into the cyclone separation chamber. Cyclone separation chamber
