Description

A vacuum generator device

technical field

The utility model relates to an original part of a vacuum generator, in particular to a vacuum generator device.

Background technique

The vacuum generator is a new, efficient, clean, economical, and small vacuum component that uses a positive pressure air source to generate negative pressure, which makes it possible to use both positive and negative pressure in places where there is compressed air, or in a pneumatic system. It becomes very easy and convenient to obtain negative pressure anywhere. Vacuum generators are widely used in the fields of machinery, electronics, packaging, printing, plastics and robots in industrial automation.

When the vacuum generator is in use, it will be connected with a vacuum suction cup, and it will be in contact with other parts through the vacuum suction cup. The vacuum suction cup and the vacuum generator are directly connected. When the vacuum suction is put into the water, it is easy to suck the water directly into the vacuum generator, which will damage the vacuum generator and destroy its work.
