The vacuum box reduces the air molecules inside the box through pressure reduction treatment, achieving a vacuum state. 

Its principle is mainly divided into the following steps:

1. Vacuum pump for air extraction: The vacuum pump pumps out the air inside the box through negative pressure effect, achieving a low pressure state.

2. Stop the pump and maintain pressure: When the pressure inside the box drops to the required vacuum degree, the vacuum pump stops pumping, and the pressure inside the box may fluctuate due to leakage or volatilization. So it is necessary to maintain the vacuum degree that required for a period of time.

3. Gas filling recovery: For environments that require the addition of inert gas, it can be added to the box through valves or other means.

4. Open the box for ventilation: After the pressure reduction process is completed, it is necessary to restore the air pressure to normal pressure by opening the box door, valve, and other means for ventilation treatment.

Summarize: Vacuum boxes have a wide range of applications and can be processed by reducing pressure to achieve a vacuum state. Its working principle is mainly achieved through depressurization pumping, effectively improving the performance and quality of materials, providing strong technical support for research, manufacturing, testing and other fields.

1. Scientific research experiments: In many scientific studies, such as materials research, physics experiments, etc., they are used to create specific vacuum environments for experimentation and observation.

2. Electronics industry: vacuum packaging, leak detection and other operations for electronic components, semiconductor devices, etc.

3. Food packaging: It can remove air inside the packaging, extend the quality guarantee period of food, and maintain the quality and taste of food.

4. Drying treatment: Used for items that require drying under vacuum conditions, such as certain drugs, fine chemicals, etc.

5. Vacuum coating: providing a vacuum environment for the coating process.

6. Aerospace field: Vacuum chambers may be used for component testing and assembly of spacecraft.

7. Medical field: Some medical devices are used in the production and testing process.
