Technical Field

[0001] The utility model relates to the technical field of vacuum generators, in particular to a plug-in type vacuum generator. Background Art

[0002] A vacuum generator is a vacuum component that uses a positive pressure gas source to generate negative pressure. It makes it very easy and convenient to obtain negative pressure in places where compressed air is available, or in places where positive and negative pressures are required at the same time in a pneumatic system. Vacuum generators are widely used in industrial automation in the fields of machinery, electronics, packaging, printing, plastics and robots. Vacuum generators have the advantages of simple structure, easy use and long service life.

Although the above structure can save structural space and improve the assembly efficiency of the vacuum generator housing, the following shortcomings still exist.

During this process, the rapid flow and impact of the air cause noise to be generated inside the vacuum generator. Utility Model Content
