Claims (16)

1. A cyclone-type dust collecting device for use in a vacuum cleaner, comprising a cyclone collector housing having an inlet port and an exhaust port, wherein the cyclone collector housing is capable of creating a vortex air stream from dust-saturated air sucked into the vacuum cleaner through the inlet port, a chamber for collecting dust attached to the body of the cyclone trap with the possibility of removal and designed to collect dust separated from the sucked air in a swirling air stream, and a unit with a netted part located at the outlet port of the cyclone trap body and designed to prevent dust flow back through the outlet port of the cyclone trap body, wherein the grating part contains a first element of the grating part having a support part resting on the outlet port of the cyclone casing trap, the second element of the node with the lattice part, attached to the lower hole. the first element of the node with the lattice part with the possibility of removal and having an outer circumferential surface, and the lattice part to form a channel in fluid communication with the outlet port on the outer circumferential surface of the second element of the node with the lattice part. 2. The device according to claim 1, in which the first element of the node with the lattice part further comprises an internal threaded part formed on the inner circumferential surface of the lower port, and the second element of the node with the lattice part contains the external threaded part formed on the outer circumferential surface of the upper part and corresponding to the internal threaded part. 3. The device according to claim 1, in which the grating part is formed by inserting a strainer into the second element of the node with the grating part, while the strainer has many small holes, and the second element of the node with the grating part has many holes in the form of windows formed on the outer circumferential surface in the radial direction. 4. The device according to claim 3, in which the strainer contains a filter frame containing an upper ring, a lower ring and two or more ribs connecting the upper and lower rings, and a mesh pressed into the filter frame so that it is placed in the holes, separated by filter frame ribs. 5. The device according to claim 4, in which the filter frame is formed of plastic, and the upper and lower rings of the filter frame are obtained by vapor deposition on the corresponding part of the second element of the node with the lattice part so that the filter frame is inserted into the second element of the node with grating, thereby forming a strainer. 6. The device according to claim 4, in which the filter frame is made of rubber and is held in place relative to the second element of the node with the grating part due to interference fit with the formation of the strainer. 7. The device according to claim 1, in which the grating part is formed by directly drilling a plurality of small ports in the outer circumferential surface of the second element of the node with the grating part. 8. The device according to claim 1, in which the node with the lattice part contains an element for preventing dust flow in the opposite direction, located at the lower hole of the second element of the node with the lattice part and designed to deflect dust trapped in the air flow passing upward from the chamber to collect dust. 9. The device of claim 8, in which the element is designed to prevent dust flow in the opposite direction, contains a cylinder installed by pressing fit in the lower port of the second element of the node with the lattice part and containing upper and lower supporting parts having two or more ribs , an axis resting on the upper and lower supporting parts, and a plate attached to the end of the axis and located at a predetermined distance from the lower end of the second element of the node with the lattice part. 10. The device according to claim 9, in which the cylinder contains a spiral guide formed in it and designed to direct the flow of air discharged through the cylinder. 11. The device according to claim 9, in which the cylinder and plate are made of rubber. 12. The device according to claim 9, in which the plate is made in the form of a cone. 13. The device according to claim 1, in which the housing of the cyclone trap contains an auxiliary handle protruding from the extension pipe of the vacuum cleaner to enable the user to capture the extension pipe. 14. The device according to item 13, in which the housing of the cyclone trap contains the upper and lower bodies, which are made separately and mate with each other, and the auxiliary handle contains a pair of parts of the handle having a symmetrical shape formed on the upper and lower bodies and paired with each other friend. 15. The device according to claim 1, in which the housing of the cyclone trap has a guide surface formed on the side wall of the inlet port and is designed to direct the flow of air sucked through the inlet port, and providing improved directivity of the sucked air, while the guide surface is formed with a given radius curvature. 16. The device according to clause 15, in which the radius of curvature of the guide surface is less than the radius of curvature of the inner circumferential surface of the body of the cyclone trap.
