Description

Technical Field

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

[0002] At present, vacuum cleaners are divided into portable, horizontal and vertical vacuum cleaners according to their structural forms. A vacuum cleaner uses the high-speed rotation of a motor to drive a fan blade group to rotate, creating a partial vacuum inside the vacuum cleaner, thereby generating a pressure difference between the inside and outside of the vacuum cleaner. This pressure difference drives air to enter from the suction port, bringing in dust and debris at the same time. The incoming air and debris pass through a series of filtering devices, such as dust filter bags and filter sheets. The dust and debris are left inside the filtering devices, while the filtered air is discharged through the motor. A vacuum cleaner mainly consists of three parts: dust raising, dust suction, and dust filtration.
