NOZZLE DEVICE COMPRISING AT LEAST ONE LIGHT-EMITTING SOURCE, AND WIRELESS CLEANING DEVICE Russian patent published in 2024 - IPC A47L5/24 A47L9/02 A47L9/30 

FIELD: consumer electronics.

SUBSTANCE: group of inventions relates to a nozzle device containing at least one light-emitting source, and a wireless cleaning device. Nozzle device configured to access the surface to be cleaned and move along the surface during the cleaning process comprises at least one light-emitting source, located on the side of the nozzle and configured to emit light from the corresponding side of the nozzle, and a control device. Control device is configured to change at least one parameter of at least one light-emitting source depending on the actual circumstances of the cleaning process between a functional value and at least one default value, which is different from the functional value, and setting a functional value of the parameter when the corresponding lateral side is at a distance equal to or less than the reference distance from the obstacle on the surface to be cleaned.

EFFECT: higher efficiency of cleaning off to one side of the device.
