description | The invention relates to a positive-pressure dust removal system for a vacuum sweeper, and the vacuum sweeper. The positive-pressure dust removal system comprises a suction fan, a dust removal device,a suction negative-pressure cavity, a first positive-pressure filtering cavity and a second positive-pressure filtering cavity. The air suction end of the suction fan is communicated with the suctionnegative pressure cavity, the air exhaust end of the suction fan is communicated with the first positive-pressure filtering cavity, the dust removal device is arranged on one side of the air exhaustend of the suction fan, and the first positive-pressure filtering cavity is communicated with the second positive-pressure filtering cavity; and the filtering precision of the second filtering positive-pressure cavity is greater than that of the first filtering positive-pressure cavity. According to the positive-pressure dust removal system, the efficiency of the suction fan is improved, garbage sedimentation is facilitated |
