FIELD: personal demand items. ^ SUBSTANCE: inventions are related to vacuum cleaner. Vacuum cleaner comprises body, where mount part of dust collection device is arranged, with the possibility to be fixed and disconnected from mount part of dust collection device and inside it has compartment for accumulation of contaminating particles. In vacuum cleaner there is at least one pressing element arranged, which lowers volume of contaminating particles accumulated in compartment for accumulation of contaminating particles, and arranged with the possibility of displacement in compartment for accumulation of contaminating particles. Device for power transfer is connected to pressing element, to transfer motive force to press element from external side and comprising slave gear connected with press element. Horizontal section of slave gear axis has the shape that differs from round shape. Vacuum cleaner has control device, which identifies number of contaminating particles accumulated in compartment for accumulation of contaminating particles. In version of design vacuum cleaner comprises dust collection device selectively installed in its body, at least one press element, which reduces volume of contaminating particles accumulated inside and is arranged inside dust collection device. Press element is put in motion by driving device, which is connected to press element in compliance with installation of dust collection device, drive gear of which is connected to press element. On dust collection device there is the first guide element, which guides dust collection device in process of installation, and on vacuum cleaner body there is the second guide element, which interacts with the first guide element. When installed in vacuum cleaner body, slave gear is inserted into location slot. In another version of design vacuum cleaner comprises dust separation device, which separates contaminating particles from air sucked into vacuum cleaner body, dust collection device connected to vacuum cleaner with the possibility of detachment and having compartment for accumulation of contaminating particles, at least one pressing element that reduces volume of contaminating particles, accumulated in compartment for accumulation of contaminating particles, and interacting with fixed element. Pressing element is installed in compartment for accumulation of contaminating particles with the possibility of displacement. Vacuum cleaner has at least one gear arranged with the possibility of driving force transfer to pressing element. At least one gear contains multiple teeth, having at least one rounded side surface. ^ EFFECT: increased dust collection volume of dust collection device due to compaction of contaminating particles accumulated in it. ^ 28 cl, 21 dwg |
