ABSTRACT:
A dust sucking/blowing device including a housing including a fan chamber for receiving a fan therein, a dust collecting sleeve fitted around the fan chamber and formed with a first and a second inlets communicating with a dust collecting room which is formed with at least one perforation for communicating with the incoming compartment of the chamber. The sleeve is further formed with an outlet for communicating with the outgoing compartment of the fan chamber. A control guide cartridge includes a hollow cartridge body formed with an inlet section fitted with the outlet of the sleeve for guiding air flow into the cartridge body, and an outlet for outward guiding the air flow from the cartridge body. When the outlet of the cartridge body is aligned with the fitting hole of the second casing, the outlet of the cartridge body permits the air flow from the fan to be outward blown from the passage of the dust sucking/blowing tube fitted with the fitting hole for blowing away dusts. When the guide sleeve is aligned with the first inlet of the sleeve and the fitting hole of the second casing, the external dusts and impurities are sucked through the passage, guide sleeve and the first inlet into the dust collecting room.
