A spring hinge structure includes a first hinge plate, a second hinge plate, and a restoring control device. The restoring control device includes an upper spindle mounted in the upper shaft tube of the first hinge plate, a lower spindle mounted in the lower shaft tube of the first hinge plate, and a spring mounted in the elongated shaft tube of the second hinge plate. A pair of juxtaposed T-shaped mounting rings made of composite plastic material are mounted between the upper shaft tube of the first hinge plate and the elongated shaft tube of the second hinge plate, and are mounted between the lower shaft tube of the first hinge plate and the elongated shaft tube of the second hinge plate respectively.

The vacuum cleaner of claim 1, wherein the dust barrel is substantially cylindrical in shape and has an open end and a closed end, the open end aligning with the closed end of the cover.3. The vacuum cleaner of claim 1, wherein the dust barrel includes a handle formed on a sidewall thereof.4. The vacuum cleaner of claim 1, wherein the locking/unlocking means comprises: a slanted surface formed on the closed end of the dust barrel, the slanted surface extending in a curve and gradually increasing in depth from a center of the dust barrel to an outer edge of the dust barrel; a fixing member including a rotary pin formed proximate a first end, a handle located at a second end, and a protrusion located between the first and second ends, the protrusion being received in and movable along the slanted surface; and a base removably mounted in the dust chamber, the base having a hole formed therein for receiving the rotary pin and supporting movement of the fixing member with respect to the slanted surface.5. The vacuum cleaner of claim 1, wherein the closed end of the cover is a spiral surface.6. An upright type vacuum cleaner, comprising: a cleaner body having an upper dust chamber, a lower motor driving chamber housing a motor, an air inflow path, and an air outflow path for interconnecting the upper dust chamber and the lower motor driving chamber; a cyclone body mounted in an upper portion of the dust chamber and connected to the air inflow path and the air outflow path, wherein the cyclone body comprises: a cover including an open end and a closed end, and a contaminant discharge port formed on the closed end of the cover; and a head portion including an air inflow pipe connected to the air inflow path for guiding the air in a diagonal direction with respect to the cover, an air outflow pipe having one end connected to a grille, the grille extending toward the closed end of the cover and being connected to the air outflow path; a dust barrel removably mounted to a lower side of the cyclone body; a suction brush mounted on a lower portion of the cleaner body, movable along a surface to be cleaned; and fine dust filtering means removably disposed in the air outflow path. 7. The vacuum cleaner of claim 6, wherein the closed end of the cover is a spiral surface.8. The vacuum cleaner of claim 6, wherein the dust barrel is substantially cylindrical in shape and has an open end and a closed end, the open end aligning with the closed end of the cover.9. The vacuum cleaner of claim 6, wherein the dust barrel includes a handle formed on a sidewall thereof.10. An upright type vacuum cleaner comprising: a cleaner body including a dust chamber, a motor driving chamber, an air inflow path, and an air outflow path, the air outflow path connecting the dust chamber with the motor driving chamber, a suction brush pivotally coupled to the cleaner body; a cyclone body mounted in the dust chamber in communication with the air inflow path and the air outflow path, the cyclone body including a head portion and a cover, the head portion including a grille extending toward a closed end of the cover, the closed end of the cover having a spiral surface forming a contaminant discharge port; and a removable dust barrel coupled to closed end of the cyclone body. 11.
