Abstract

The vacuum cleaner with parallel dust removing devices includes at least two parallel arranged upstream cyclonic separators, each of which has one downstream separator. The present invention has increased ventilation amount, reduced volume and high dusting efficiency. The downstream cyclonic separators are in diffusion structure and have airflow inside the barrels in rotating and reducing centrifugation state, and have less airflow pressure loss, high dusting effect, no dust flying and no secondary pollution.

Description

technical field

[0001] The invention relates to a dust removal device of a side-by-side vacuum cleaner. Background technique

[0002] A filter device is installed in a traditional vacuum cleaner to filter the inhaled dirty air and keep the dust particles in the dust collection device. Therefore, after using this type of vacuum cleaner for a period of time, the user should clean or replace the filter device. Otherwise, the filter holes of the filter device will be blocked by fine dust, which will increase the resistance of the vacuum motor, and even burn out the motor in severe cases, which not only brings trouble to the user, but also affects the performance and life of the vacuum cleaner.

[0003] In recent years, based on the principle of cyclone separation, manufacturers have replaced filter devices with cyclone dust collectors, which have achieved better dust removal effects, and are therefore widely used in vacuum cleaners. The cyclone dust removal device is provided w...
