SMART DELIVERY DEVICE

WIPO Patent Application WO/2021/142877

A1

A smart delivery device (3) comprises an antenna (31), a reader (32), a battery (33), a driving mechanism (34), an execution mechanism (35), and a position-limiting mechanism (36). The antenna is used to receive an electromagnetic signal from an electronic tag (21) on a sliding sleeve (2). The reader is connected to the antenna, and is used to identify the received electromagnetic signal. The driving mechanism is connected to the reader, such that the reader, upon identifying the electromagnetic signal, controls the driving mechanism to move. The execution mechanism is connected to the driving mechanism, and the position-limiting mechanism is connected to the execution mechanism. The driving mechanism drives the execution mechanism to move, such that the position-limiting mechanism extends out of the smart delivery device. The position-limiting mechanism can abut a sliding-sleeve inner tube (25), and push the sliding-sleeve inner tube to slide relative to a sliding-sleeve outer tube (24), thus exposing a liquid outlet hole (23) on the sliding sleeve. The battery is respectively connected to the antenna, the reader and the driving mechanism, and is used to supply power to the smart delivery device.
