Abstract

The invention discloses an automatic dust-falling dust remover, belongs to the field of dust removers of environmentally-friendly equipment, and in particular relates to a dust falling structure of the dust remover. The invention aims to provide a novel dust removal which can reversely blow dust without high-pressure air and backwards blow the dust falling structure by using natural air outside the dust remover or micro pressure air from an air outlet pipe of a fan. The automatic dust falling dust remover comprises a dust removal device, the fan, an air inlet pipe device, an air exhaust pipe device, a dust falling control device and the like. The automatic dust falling dust remover is characterized in that the dust falling device is not provided with a high-pressure air source; and a channel for making the natural air outside a dust removal chamber or the micro pressure air from an outlet of the fan reach a dust removal bag opening and a valve capable of controlling switching of corresponding functions are added. After the dust removal chamber is divided, when most dust falls down, the dust removal chamber is in a negative pressure state; and only if an air inlet of the dust removal bag opening is pressurized, a dust removal bag can be instantly converted from the negative pressure air exhaust dust removal state into a dust removal chamber positive pressure air supply state, so that the aim of automatically falling the dust without power can be fulfilled.
