Title:
AUTOMATIC EXTRACTION DEVICE FOR PERFUME FILLING, AND CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2024/037501
Kind Code:
A1
Abstract:
An automatic extraction device for perfume filling, and a connector (9). In the automatic extraction device, a liquid nozzle (11) is formed at the front end of a piston barrel (1), and a piston (2) extends into a cavity of the piston barrel (1); a pressing member (4) is mounted at the rear end of the piston rod (3), and extends to the outside of the piston barrel (1); a bushing (6) is fixed in the piston barrel (1); the front end of the piston rod (3) passes through the bushing (6) and is then fixedly connected to the piston (2); a space between the bushing (6) in the piston barrel (1) and the liquid nozzle (11) forms a compression space (10) of the piston (2); and thrust generated by a compression spring (5) on the piston rod (3) makes the piston (2) have a tendency to move away from the liquid nozzle (11). An external force acting on the pressing member (4) overcomes the elastic force of the compression spring (5), so that the piston rod (3) is pushed to drive the piston (2) to compress the compression space (10) in the cavity; and after the external force is released, the elastic force of the compression spring (5) drives the piston (2) reset, such that negative pressure is generated using the compression space (10), and thus perfume is extracted from the liquid nozzle (11).
