Vacuum cleaner {VACUUM CLEANER}

The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner capable of effectively removing dust and foreign matter sticking to a cleaning object by hitting the object to be cleaned, thereby improving the dust collecting efficiency.

 The vacuum cleaner generates a suction force by driving an electric blower fan incorporated in the housing, and sucks and filters air containing foreign matter such as dust by suction force of the air. The filtered air is discharged to the outside for cleaning. The vacuum cleaner is classified into a canister type, an upright type, and a handy type.

Generally, a vacuum cleaner includes a housing, an electric blower fan, and a filter unit. The housing includes an air inlet formed with a suction port forward of the floor to introduce air, an air outlet formed behind the outer surface to discharge air, and an air passage formed to guide the flow of air between the air inlet and the air outlet . The electric blower fan is installed in an air passage and is constituted by a fan which is rotated by the driving of an electric motor and an electric motor to generate a suction force of air.

In such a vacuum cleaner, when the electric motor of the electric blower fan is driven to rotate the fan, the air is sucked through the inlet, and then discharged through the air passage and the air outlet. The filter unit filters and collects foreign substances in the air sucked through the air inlet.

In recent years, a vacuum cleaner having a striking device has been developed and used so as to effectively separate and suction foreign substances such as dust adhering to a cleaning object.
