Description

technical field

[0001] The present invention relates to the invention of a vacuum cleaner, in particular to the invention of a dust collecting device of a cyclone type vacuum cleaner. Background technique

[0002] The vacuum cleaner is a device that uses the vacuum pressure generated by the vacuum motor installed inside the fuselage to suck the air containing dirt, then filters it inside the fuselage, collects and finally removes the dirt.

[0003] In order to filter the inhaled air, the filter generally adopts a bag-shaped paper filter. This paper filter allows air to pass through, but prevents dirt such as dust from passing through and remaining in the bag, thereby removing dirt such as dust contained in the air.

[0004] However, after the vacuum cleaner with paper filter is used for a long time, after a certain amount of dirt is accumulated inside, not only the suction of the vacuum cleaner drops obviously, but also if the paper filter is not replaced in time, it will b...
