The vacuum box reduces the number of air molecules inside the box through decompression treatment, achieving a vacuum 

1. Vacuum pump pumping:  vacuum pump pumps out the air from the box through the negotive pressure efect to reach a low pressure site;

2. Stop the pump pressure: when the pressure in the box drops to the required vacuum degree, the vacuum pump stops pumping, and the pressure in the box will fluctuate due to leakage or volatilization. So you need to maintain the agreed vacuum for a while;

3. Gas filling recovery: for the environment that needs to add inert gas, it can be added into the box through the valves;

4. Open the container for ventilation: When the decompression treatment is completed, the air pressure needs to be restored to the normal pressure state, which can be ventilated by opening the door and valve.

Summary: Vacuum boxes have a wide range of applications and can be treated by reducing pressure to reach a vacuum state. Its working principle is mainly achieved through vacuum pump gas, effectively improve the performance and quality of materials, and provide strong technical support for scientific research, manufacturing, testing and other areas.

1. Scientific research experiments: in many scientific research, such as material research, physics experiments, etc., used to create a specific vacuum environment for experiments and observations.

2. Electronics industry: vacuum packaging and leak detection of electronic components and semiconductor devices.

3. Food packaging: It can remove the air in the packaging, extend the shelf life of food, and maintain the quality and taste of food.

4. Drying treatment: for some items that need to be dried under vacuum conditions, such as some drugs, fine chemicals.

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

6. Aerospace field: Spacecraft parts testing and assembly may use the vacuum box.

7. Medical field: some medical equipment will be used in the production and testing process.
