FIELD: production of cyclone dust-trapping device of the vacuum cleaner. ^ SUBSTANCE: the invention is pertaining to the cyclone dust-trapping device and may be used in the vacuum cleaner and ensures an increase of a dust-trapping efficiency of the foreign particles contained in the air due to a capability to fulfill a set of times of the centrifuging processes for their sorting by sizes, a decrease of noise and an increased service life of the filter. The device contains the body of the lower cyclone trapper intended for a centrifuging and trapping of the large foreign particles contained in the air entered from outer space and at least one body of the upper cyclone trapper located at the upper part of the body of the lower cyclone trapper and intended for centrifuging and trapping of the small foreign particles contained in the air coming out of the body of the lower cyclone trapper with the purpose of sorting particles by size, and the container for the dust collection placed with a capability of disconnection from the body of the lower cyclone trapper. The container has a section for collection of the upper dust and used for collection of the foreign particles exposed to the centrifuging in the body of the upper cyclone trapper and a section for collection of the lower dust used for collection of the foreign particles, exposed to centrifuging in the body of the lower cyclone trapper. ^ EFFECT: the invention ensures an increase of a dust-trapping efficiency of the foreign particles contained in the air, a decreased noise and an increased service life of the filter. ^ 7 cl, 7 dwg |
