Claims (14)

1. A vertical vacuum cleaner comprising a housing having a dust chamber and an engine compartment configured in said dust chamber; a suction brush connected to the cleaner body to move along the surface to be cleaned; and a cyclone dust collector arranged to be removed in the dust chamber of the vacuum cleaner body to isolate and collect, under the action of centrifugal force, small dust particles and large particles of pollutants from the air that enters through the suction brush, the cyclone dust collector including a top cover having a first air intake corresponding to the suction a sleeve for connecting to a suction brush and a dust chamber, and an air outlet corresponding to an outlet sleeve for connecting to a dust chamber and a motor tsekom; a generally cylindrical external cyclone receiver having open upper and lower ends, the external cyclone receiver being connected to the top cover; an internal cyclone receiver connected to the top cover and housed in an external cyclone receiver; and a lower cover mounted at the lower open end of the external cyclone receiver, said lower cover providing access to dust and contaminants collected in the internal and external cyclone receivers.  2. The vertical vacuum cleaner according to claim 1, characterized in that the inner cyclone receiver comprises an air distribution grill having many small openings and a second air intake for directing the air flow passing through the air distribution grill in the form of an air vortex and creating a centrifugal force due to which separation occurs dust from the air and collecting said dust in a dust collector.  3. The vertical vacuum cleaner according to claim 1, wherein the first air inlet of the inner cyclone receiver directs air containing dust and contaminants into the vortex stream, while the centrifugal force of the vortex stream separates the pollutants from the air; the internal cyclone receiver has an outlet for the pollutant through which the pollutants separated from the air are discharged into the external cyclone receiver.  4. The vertical vacuum cleaner according to claim 2, characterized in that the first and second air intakes of the upper cover partially overlap each other.  5. The vertical vacuum cleaner according to claim 2, characterized in that the top cover has an exhaust pipe extending downward from the air outlet, and a skirt expanding downward from the end of the exhaust pipe and having a gradually increasing diameter; said skirt improves dust collection efficiency by increasing air flow rate.  6. The vertical vacuum cleaner according to claim 5, characterized in that the exhaust pipe has a spiral groove to increase centrifugal force.  7. The vertical vacuum cleaner according to claim 3, characterized in that the top cover includes an outlet pipe, wherein said exhaust pipe extends downward from the air outlet and has a first skirt extending downward from the end of the vacuum cleaner; said first skirt has a gradually increasing diameter to prevent backflow of contaminants collected in the inner cyclone receiver.  8. The vertical vacuum cleaner according to claim 7, characterized in that the exhaust pipe includes a second skirt extending downward from the middle level of the exhaust pipe, the second skirt having a gradually increasing diameter, in order to direct contaminants trapped in the air in the inner cyclone receiver to remove them through the outlet.  9. A vertical vacuum cleaner according to any one of paragraphs. 1-3, characterized in that the internal cyclone receiver tapers down from the average level of the vacuum cleaner to form a gradually increasing gap between the internal and external cyclone receivers, while a gradually increasing gap reduces the air flow rate and prevents the formation of backflow of pollutants collected in the external cyclone receiver .  10. A vertical vacuum cleaner according to any one of paragraphs. 1-3, characterized in that it further comprises a pipe to prevent backflow, which extends to a predetermined height from the center of the inner cyclone receiver, to direct back the upward swirl air flow from the bottom of the inner cyclone receiver and to prevent the formation of a backflow of pollutants.  11. A vertical vacuum cleaner according to any one of paragraphs. 1-3, characterized in that the lower cover is screwed to the open end of the external cyclone receiver.  12. The vertical vacuum cleaner according to claim 11, characterized in that the pipe to prevent backflow is mounted in the center of the bottom cover.  13. A vertical vacuum cleaner according to any one of paragraphs. 1-3, characterized in that the first side of the lower cover is pivotally connected to the lower end of the external cyclone receiver and in which the second side of the lower cover has a lock that interacts with the locking protrusion that is formed on the external cyclone receiver, while the lower cover is hinged provides removal of pollutants collected in the internal and external cyclone receivers.  14. The vertical vacuum cleaner according to claim 13, characterized in that the nozzle to prevent backflow is mounted on the lower open end of the inner cyclone receiver using multiple ribs.
