Title:
NOZZLE ASSEMBLY, NOZZLE DEVICE AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/109342
Kind Code:
A1
Abstract:
A nozzle assembly, comprising: a nozzle body (10) comprising a liquid inlet runner (11) and a liquid outlet runner (13); a cover body (20) mounted at the nozzle body (10) and internally provided with an accommodating cavity (22); a pressure relief regulator (30) cooperated with the cover body (20); and a seal assembly (40) provided in the accommodating cavity (22) and comprising a seal valve plate (41), a connector (43) and an elastic member (45). The seal valve plate (41) is configured to seal the conduction between liquid inlet runner (11) and the liquid outlet runner (13), the pressure relief regulator (30) drives the seal valve plate (41) by means of the connector (43), and the elastic member (45) is configured to provide an elastic restoring force to the connector (43) so that the seal valve plate (41) is in a normally closed state. The pressure relief regulator (30) is operated to drive the seal valve plate (41) to be switched between a first working position and a second working position by means of the connector (43). When the seal assembly (40) is located in the first working position, the seal valve plate (41) is open, and the liquid inlet runner (11) and the liquid outlet runner (13) are conducted, and when the seal assembly (40) is located in the second working position, the seal valve plate (41) is closed, and the conduction between the liquid inlet runner (11) and the liquid outlet runner (13) is closed.
