Abstract
The invention relates to a vacuum generator which has the innovative points that the vacuum generator comprises an exhaust port, a Laval nozzle, a nozzle, a negative pressure cavity, a vacuum port, a shell and an air inlet; the vacuum generator uses compressed air as power; according to the vacuum generator, by enabling the compressed air to enter an airflow nozzle, airflow flows out of the nozzle at a high speed, a suction effect is generated, and finally, the compressed air and the sucked air are exhausted into the atmosphere through a receiver nozzle. The vacuum generator adopting the design is simple in structure, low in manufacturing cost, small in adsorption volume, short in response time, low in surface leakage rate and low in air consumption.
Description
technical field [0001] The invention relates to a vacuum device, in particular to a vacuum generator. Background technique [0002] Vacuum generators are widely used in broadcasting, communication, television, radar, navigation, industrial automation, machinery, electronics, packaging, printing, plastics and robots. Vacuum generators need to absorb and transport various materials, especially suitable for adsorption Fragile, soft, thin non-ferrous, non-metallic materials or spherical objects, ordinary vacuum generators use vacuum pumps driven by motors, which generate high energy consumption, large volume, heavy weight and require regular maintenance. [0003] In addition, during the application process, ordinary vacuum generators have unstable pumping volume, difficult control of vacuum degree, and inaccurate intermittent time during intermittent work, resulting in inaccurate vacuum generator movements. Contents of the invention [0004] The technical problem to be solved...
