WET CLEANING VACUUM CLEANER Russian patent published in 2025 - IPC A47L9/16 

FIELD: domestic articles or appliances.

SUBSTANCE: vacuum cleaner (10) for wet cleaning, comprising: a dirt inlet; motor (14) and fan (16) to provide suction to the dirt inlet; cyclone unit (18) for separation of liquid and particles from the flow created by the suction of the motor and the fan; at that, the cyclone unit has axis (22) of rotation of the cyclone. At that, cyclone unit comprises outer casing (30) with outer sidewall (32) with opening and end surface (36) to make the boundary of cyclone unit inner space and communicated with outer sidewall (32). End surface is located at one end of the cyclone unit along the axis of the cyclone, inlet (38) for the main flow to said opening in the outer side wall, having a diameter of the hydraulic inlet; inlet branch pipe (39) for the main flow, which is connected to inlet hole (38) for the main flow, and outlet hole (40) for the main flow from the external housing. Main flow inlet (38) is located at said one end of the cyclone unit, but is spaced inward from end surface (36) by a separation distance (d1) of at least 0.1 of the diameter of the hydraulic inlet, and inlet branch pipe (39) for the main flow extends in a direction deviated from the perpendicular to the axis of the cyclone and faces said surface.

EFFECT: prevention of formation of large drops, which can follow along the path to the outlet hole of the main flow.
