Description
Technical Field
The invention relates to the field of dust collectors, in particular to a dust collector dust barrel with a speed reducing structure and a dust collector.
Background
In the dust collector used at present, the principle of the diffusion type cyclone dust collector is that when dust enters a dust cup to realize dust separation, larger-particle dust is spirally dropped into an outer dust barrel of the dust cup, smaller-particle dust enters a secondary cyclone system through a small hole and finally spirally dropped into the bottom of an inner dust barrel through a secondary air inlet at the upper part, and the diffusion type cyclone dust collector is a structure widely used at present, effectively realizes the separation of large and small particles of the dust, and solves the problem that the suction of the dust collector is easy to be lost in the dust collection process.
However, the above structure has some drawbacks, if the second cyclone system is too fast in speed reduction, the air data performance (air date) of the whole machine is greatly lost, if the second cyclone system is too slow in speed reduction, dust suction in the second ash storage barrel is arbitrarily caused to generate a dust-raising phenomenon, and the filter is blocked to influence the suction force of the whole machine.
