Title:
AIR PRESSURE VACUUM GENERATOR
Document Type and Number:
WIPO Patent Application WO/2018/086113
Kind Code:
A1
Abstract:
Disclosed is an air pressure vacuum generator, the air pressure vacuum generator comprising an air outlet (1), a Laval spray pipe (2), a spray nozzle (3), a negative pressure cavity (4), a vacuum port (5), a housing (6) and an air inlet (7). The air pressure vacuum generator uses compressed air as power. The air pressure vacuum generator enables an air flow to flow out of the spray nozzle at high speed, by means of making the compressed air enter an air flow spray nozzle, thereby generating suction effect, and finally enabling the compressed air and the sucked air to discharge into the atmosphere through a receiver spray nozzle. The air pressure vacuum generator has a simple structure, low production costs, small adsorption volume, short response time, small amount of surface leakage and small air consumption.
