Abstract

The invention discloses an induction heating phase-change type micro jet driver and belongs to the field of micro drivers. A coil (3) is arranged around the periphery of a driver casing (1) in a wrapping manner and insulating paint (2) is coated on the periphery of the driver casing (1) and the coil (3); a heating core (6) is mounted in an inner chamber (8) of the driver casing (1); the two ends of the heating core (6) are aligned with the two ends of the coil (3); a power module I (10) is used for supplying power for a pulse generator (11), and the high-frequency impulse generated by the pulse generator (11) is supplied to a relay (12); a power module II (16) is used for supply power for a single-chip system (15), and the single-chip system (15) is communicated with the control terminal of the relay (12); a circuit output terminal I ( 13) is communicated with a coil terminal I (4); and a circuit output terminal II (14) is communicated with a coil terminal II (5). According the invention, a blasting type injection of gas-liquid mixture is used as a driving force, so that the driver realizes forward movement.

Description

technical field [0001] The present invention is a kind of micro-driver, specifically a kind of high-frequency pulse induction heating made by micro-machining technology, so that the liquid in the heating core can be rapidly vaporized, and the volume can be rapidly expanded by nearly 1000 times, and the volume-expanded vapor-liquid mixture can be The injection port is ejected, and the ejection reaction force is used as the driving force of the micro-driver. Micro-actuators are an important part of intelligent devices such as micro-underwater robots, robotic fish and micro-manipulation, and belong to the field of micro-drives and micro-actuators. Background technique [0002] Micro underwater actuators based on modern microprocessing technology have the advantages of low power consumption, low cost, and small size, and have important applications in micro underwater robots, micro robot fish, micro drives, underwater detection and sensing. At present, most of the micro underwa...
