Ejector structure capable of rapidly and automatically switching nozzles

Abstract

The invention provides an ejector structure capable of quickly and automatically switching nozzles, which comprises a shell, at least two groups of nozzle devices and a sliding rail device, and a sliding rail of the sliding rail device comprises a sliding groove section and a clamping groove section; the nozzle of any nozzle device slides along the sliding rail, when the nozzle slides from the sliding section to the clamping groove section, the nozzle pushes the nozzles of other nozzle devices in the reset direction of the limiting elastic pieces so that the nozzles of other nozzle devices can be unlocked from the clamping groove section, and the reset elastic pieces drive the nozzles of other nozzle devices to reset along the sliding rail device. Through sliding of the two sliding blocks, unlocking operation on the other bad block can be completed in the moving process of one sliding block, so that switching of nozzles with different flow speeds is completed, the switching process is convenient and rapid, the output power response speed is high, delay is low, a system using the ejector can be automatically adjusted when the power needs to be changed, and the switching efficiency is improved. And the reliability and efficiency of the equipment are ensured.
