SPRAYING DEVICE (EMBODIMENTS) Russian patent published in 2024 - IPC B05B11/02 

FIELD: spraying.

SUBSTANCE: group of inventions relates to spraying devices (embodiments). Spraying device includes a bottle part, a sleeve and a motor. Motor includes a spring which, when compressed, creates pressure in the chamber containing an amount of fluid medium capable of discharging from the bottle part. Sleeve and the motor can be screwed on the bottle without spring compression. Turning the sleeve relative to the bottle by the user creates pressure in the chamber containing the fluid medium to exit the bottle. User is provided with audio and/or tactile feedback when turning the cartridge, which allows the user to select the amount of fluid to be dispensed. Motor includes the main spring, which, when compressed, creates pressure in the chamber containing the amount of fluid medium capable of dispensing from the bottle. Spring is enclosed between cup and cover, connected to each other by fusion.

EFFECT: group of inventions provides high-quality spraying and improved quality of spraying viscous media by reducing pressure losses on the flow path.
