Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a cyclone separation vacuum cleaner. Background Art

[0002] A cyclone separator is a device used to separate gas-solid systems or liquid-solid systems. The working principle is to rely on the rotational motion caused by the tangential introduction of airflow to throw solid particles or liquid droplets with large inertial centrifugal force to the outer wall to separate. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in the sealed shell, absorb dust, and store the dust in the filtration system. Over time, the vacuum cleaner filter element absorbs a large amount of dust, resulting in a decrease in the suction power of the vacuum cleaner and a shortened lifespan. Therefore, people will connect a cyclone separator in series at the front end of the vacuum cleaner to store most of the dust in the cyclone separator, and only a small amount of dust will enter the vacuum cleaner filtration system, thereby protecting the vacuum cleaner filter element and increasing the lifespan of the vacuum cleaner.

[0003] At present, most cyclone separation vacuum cleaners have poor separation effects, and dust and gas are easily blown up inside. If not handled properly, dust will always remain inside the separator, reducing the service life of the vacuum cleaner, which is quite troublesome. Therefore, those skilled in the art provide a cyclone separation vacuum cleaner to solve the problems raised in the above background technology. Utility Model Content
