Handheld cleaning device

Abstract

The invention discloses a handheld cleaning device, comprising a floor brush component and a body component. The floor brush component comprises a dirty air inlet and a first cyclone separator; an airinlet of the first cyclone separator is in fluid communication with the dirty air inlet; the body component is movably connected with the floor brush component; the body component includes a second cyclone separator; an air inlet of the second cyclone separator is in fluid communication with an air outlet of the first cyclone separator such that an air flow separated by the first cyclone separator runs to the second cyclone separator for secondary separation. The handheld cleaning device according to the invention has the advantages that since the floor brush component has the first cyclone separator capable of pretreating an air flow, separation load can be relieved for the second cyclone separator of the body component, dust collection space required by the second cyclone separator is downsized, the second cyclone separator has less structural complexity, lower cost and reduced weight, and the problems are solved that, for instance, the second cyclone separator experiences flow choking.

Description

technical field [0001] The invention relates to the field of hand-held cleaning equipment, in particular to a hand-held cleaning equipment. Background technique [0002] The floor brush for a vacuum cleaner in the related art does not have a separation structure, and large particles of dust and hair directly enter the dust cup on the body through the metal tube of the floor brush for separation. However, limited by the effective ash capacity of the dust cup, after a period of use, the dust cup is easily blocked, and the entire airflow channel cannot be aired smoothly, resulting in overheating of the vacuum motor and affecting the user's use. At the same time, large particles of dust and hair are separated in the dust cup, which increases the separation load of the dust cup and reduces the separation efficiency of the dust cup. Moreover, the dust cup not only needs to separate the large particles of dust and hair, but also separates the fine particles of dust, which complica...

AI Technical Summary

Problems solved by technology

However, due to the limitation of the effective ash capacity of the dust cup, after a period of use, the dust cup is easy to be blocked, and the entire airflow channel cannot be aired smoothly, resulting in overheating of the vacuum motor and affecting the user's use

At the same time, large particles of dust and hair are separated in the dust cup, which increases the separation load of the dust cup and reduces the separation efficiency of the dust cup

Moreover, the dust cup not only needs to separate the large particles of dust and hair, but also separates the fine particles of dust, which complicates the separation structure in the dust cup. The separation structure of the dust cup occupies most of the volume of the dust cup, making the dust cup The effective dust storage volume is reduced, and the dust cup is heavier at the same time, which affects the user's comfort

Moreover, the separation of large particles of dust and hair in the dust cup will increase the frequency of cleaning the dust cup by the user and affect the comfort of the user
