Description
Technical Field
[0001] The utility model belongs to the technical field of vacuum generators, and more specifically relates to a filterable vacuum generator. Background Art
[0002] A vacuum generator is a new, efficient, clean, economical, and small vacuum component that uses a positive pressure gas source to generate negative pressure. The traditional use of a vacuum generator is to cooperate with a suction cup to adsorb and transport various materials. It is especially suitable for adsorbing fragile, soft, thin non-ferrous, non-metallic materials or spherical objects.
[0003] When using the vacuum generator, the gas enters the chamber inside the shell from the air inlet pipe, and then is discharged from the air outlet pipe. At this time, negative pressure is formed at the vacuum tube, and then the air at the vacuum tube is discharged from the air outlet pipe. At this time, vacuum is formed at the vacuum tube for adsorption. When air enters the air inlet pipe, debris in the air can easily enter the chamber inside the shell. When there are too many debris, the chamber inside the shell can be easily blocked, which will affect the use effect of the vacuum generator. Utility Model Content
