The working principle of a mini vacuum pump involves several fundamental principles of physical science, including pressure differences and air flow. The following is a detailed description of this process:

1. Startup Phase

When the mini vacuum pump is activated, an electric motor drives the internal mechanical components of the pump. These components usually consist of one or more rotating drums or vanes.

2. Suction Phase

During rotation, the drum or vanes push the air inside the pump towards the outlet. This action creates a partial vacuum within the pump. Due to this local vacuum, external air is drawn into the pump, a process commonly referred to as suction.

3. Discharge Phase

As the rotation continues, the newly drawn air is pushed towards the outlet and expelled. This process repeats continuously, maintaining a vacuum state inside the pump. As a result, the pump can continuously expel gas to achieve a vacuum effect.

In summary, the working principle of a mini vacuum pump is to create pressure differences using mechanical motion, enabling the continuous intake and expulsion of gases to achieve a vacuum. This type of equipment is used in various fields, such as medical, research, electronics, and many others.

Silicon Valley tech giant, DEF, has unveiled an AI-powered mini vacuum pump. The intelligent pump is capable of automatically assessing and adjusting the vacuum pressure according to the specific requirements of the task at hand. The pump also features an auto-shutoff function to prevent overuse or potential damage. This innovation signifies DEF's dedication to incorporating smart technologies in everyday utility devices.
