Abstract

The invention relates to a dust collecting device and a blowing and sucking machine with the same. The dust collecting device comprises a body, a dust inlet, an air discharge part and an adjusting part, wherein the dust inlet is arranged in the body, the ventilation rate of the air discharge part is higher than that of the body, and the adjusting part can adjust the air discharge area of the air discharge part. By adjusting the air discharge area of the air discharge part, the ventilation performance of the dust collecting device can be adjusted so as to satisfy the users' different sucking efficiency requirements on the blowing and sucking machine.

Description

technical field [0001] The invention relates to a dust collecting device and a blower with the dust collecting device. Background technique [0002] The blower is a power tool with dual functions of blowing dust and vacuuming. It is usually used as a tool for cleaning gardens, streets and other grounds. Existing air blowers usually include a blower main body that can be switched between blowing and suction functions. The main body includes a fan that generates airflow and a motor that drives the fan. And the dust collection device used to contain the sucked leaves and dust in the suction state. When working in the blowing mode, the blower can gather the dust or garbage scattered around by the blower to facilitate collection; when working in the suction mode, the blower is used to absorb dust, branches and leaves, etc. At this time, the dust suction wind pressure generated by the blower sucks the leaves, dust and the air mixed with dust into the suction pipe through the noz...
