Title:
COSMETIC FORMULA ATOMIZATION DEVICE WITH PISTON-SPRING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2024/082208
Kind Code:
A1
Abstract:
A system (10) for atomizing and ejecting a formula including a tank (100), a nozzle (910) fluidly connected to the tank (100) including a Venturi tube (200) and a tip (270), a cylinder (300) with an outlet hole (330), the outlet hole (330) fluidly connected to an inlet (232) the Venturi tube (200), a piston (400) arranged in the cylinder (300) so as to be displaceable in the cylinder (300), a driving unit (500) for the displacing of the piston (400) in a direction in which a volume of an air intake space in the cylinder (300) increases, an elastic member (600) deformed according to the displacement of the piston (400) and that stores an elastic energy while the piston (400) is being displaced, where the driving unit (500) includes an elastic energy release mechanism that releases the elastic energy, causing the piston (400) to rush in and a vibration, and a dampener (800) on the nozzle (910), positioned between the Venturi tube (200) and the tip (270), where the dampener (800) reduces the vibration.
