As for the evacuation port, it communicates with the outlet of the sterilization chamber 11. Because the steam ejector 4 is arranged in the steam chamber, the steam is accelerated and ejected from the steam inlet to the steam outlet, when the high-speed steam passes through the evacuation port between the steam inlet and the steam outlet, the evacuation port generates negative pressure, and the negative pressure can extract air and moisture in the sterilization cavity 11 and realize the vacuum pumping of the sterilization cavity 11.
In view of the structural function of the pulse vacuum sterilizer applied to the vacuum circulation system, the sterilization cavity 11 of the sterilization chamber 1 needs to be periodically in the sterilization operation environment and the vacuum environment where steam is introduced, therefore, the vacuum circulation system provided by the invention utilizes the communication structure of the circulation pipeline formed by connecting the water tank 2, the steam generator 3 and the steam ejector 4 end to end and the sterilization cavity 11, not only utilizes the steam generator 3 to provide steam for the sterilization cavity 11, but also utilizes the evacuation port of the steam ejector 4 to realize the vacuum pumping operation of the sterilization cavity 11, and simultaneously, steam and water circulate between the circulation pipeline and the sterilization cavity 11, thereby realizing the recycling of working media and being suitable for the long-term operation of the pulse vacuum sterilizer.

Therefore, by utilizing the heat dissipation function of the first heat exchanger 6, the working medium can be changed from a gas state to a liquid state through cooling, and the working medium can be recycled after being conveniently subjected to the water tank 2.
Wherein, the first heat exchanger 6 can adopt the air cooling principle to realize the heat dissipation.

The outer heat preservation cavity 12 can heat the sterilization cavity 11 in the sterilization process, so that the temperature of the sterilization cavity 11 can be better maintained, and the sterilization effect of the sterilization cavity 11 can be improved.
With respect to the structure and principles of the insulating chamber 12 for achieving insulation, including, but not limited to, electrical heating or water or steam heating.

Based on this connection, the water and the steam in the steam ejector 4 and the water and the steam in the heat preservation cavity 12 all need to enter the water tank 2 via the first heat exchanger 6, and therefore, the first heat exchanger 6 can simultaneously meet the requirement of cooling the water and the steam flowing out of the steam ejector 4 and the heat preservation cavity 12. Reference may be made to fig. 1 and 3.
Further, the heat exchanger also comprises a second heat exchanger 7, and the second heat exchanger 7 is arranged between the sterilization cavity 11 and the evacuation port of the steam ejector 4 and used for cooling the working medium when the evacuation port evacuates the sterilization cavity 11.
