Claims (15)

1. A cyclone-type dust collector for a vacuum cleaner comprising a cyclone body comprising an air inlet and an air outlet for forming an air vortex from dusty air drawn into the air inlet, a dust collector removably attached to the cyclone body to separate dust and dirt from an air vortex from dusty air and the collection of dust and dirt separated in it, and a grating unit located near the air outlet of the cyclone body to prevent backflow and dust and dirt into the air outlet of the cyclone body, while the grating unit further comprises a first grating element having a support element supported in the air outlet of the cyclone body, a second grating element having a grating section that contains many small through holes, to provide fluid connections with the air outlet, and a connecting element by which the first lattice element and the second lattice element are connected to each other with the possibility of separation Eden. 2. The device according to claim 1, in which the first lattice element has a first connecting groove, and the second lattice element has a second connecting groove, each groove is formed with a given shape along the entire length of the outer surface of the corresponding connecting end of the first and second lattice elements, and in which the connecting element has a first connecting protrusion having a shape consistent with the shape of the first connecting groove, and a second connecting protrusion having a shape consistent with the shape of the second c the connecting groove, throughout the inner contour of the connecting element to ensure the connection of the connecting element with the first and second connecting grooves. 3. The device according to claim 2, in which the connecting element is made of flexible material, and the second connecting protrusion has a hemispherical shape formed with an inwardly facing semicircle, so that the second lattice element is easily attached to the connecting element and detachable from the connecting element. 4. The device according to claim 3, in which the connecting element has a first conical section formed on the outer surface, while the diameter of the first conical section gradually increases as you move away from the first connecting protrusion, the first conical section is formed to prevent backflow of dirt into the exhaust channel. 5. The device according to claim 3, in which the connecting element has a second conical section formed on the inner surface, while the diameter of the second conical section gradually increases as you move away from the second connecting protrusion, the second conical section is formed to guide the connection of the second lattice element to the connecting an element. 6. The device according to claim 4, in which the first cone-shaped portion has an upper end and a lower end and is formed on the outer surface of the connecting element so that the diameter of the first cone-shaped part gradually increases towards the lower end. 7. The device according to claim 5, in which the second conical section of the connecting element having an upper end and a lower end is formed on the inner and lower side of the connecting element so that the diameter along the upper end and the lower end of the second conical section gradually increases towards the lower the end. 8. The device according to claim 1, in which the second element of the lattice includes an open part having a large number of radii through holes and formed near the upper side, and a closed part formed near the lower side, and further comprises a mesh attached to the open parts of the second element of the lattice. 9. The device according to claim 1, in which the grating unit further comprises an element that prevents the countercurrent of air connected to the second element of the grating, to prevent the upward movement of dust in the air flow from the bottom of the dust collector. 10. The device according to claim 9, in which the element that prevents the countercurrent of air, further comprises a cylindrical body having upper and lower supporting elements, each of which contains at least two ribs, while the cylindrical body is inserted by interference fit into the lower the side of the second lattice element, a rod supported by the upper and lower supporting elements, and a plate connected to the end of the rod and separated from the lower end of the second lattice element. 11. The device according to claim 10, in which the cylindrical body has a spiral guide formed in it, for the direction of movement of the air flow. 12. The device according to claim 10, in which the cylindrical body and plate are made of rubber. 13. The device according to claim 10, in which the plate has a conical shape. 14. The device according to claim 1, in which the cyclone body has a guide element located on the side wall of the air inlet channel of the cyclone body, including a guide surface having a predetermined radius of curvature for the direction of movement of air drawn into the air inlet channel, and for increase the stability and direction of the air vortex. 15. The device according to 14, in which the radius of curvature of the guide surface is less than the radius of that part of the cyclone body in which the air vortex is supported.
