Technical Field

[0001] The utility model relates to the technical field of steam sterilization equipment, in particular to a cylinder structure for a sterilizer. Background Art

[0002] A steam sterilizer is a device commonly found in medical and laboratory settings, used to disinfect and sterilize items under high temperature and high pressure conditions. The steam sterilizer uses high-pressure steam to kill bacteria, viruses, and other microorganisms in a high-temperature environment usually reaching 121°C. The high temperature and high pressure conditions of the steam are the key to achieving effective sterilization. Since the inner cylinder of the steam sterilizer needs to place the items to be disinfected, it is necessary to divide the space of the inner cylinder, and thus a cylinder structure for a sterilizer is proposed.

[0003] The Chinese utility model patent publication number: CN 221206202 U, discloses a vertical pressure steam sterilizer. This sterilizer quantitatively replenishes water for the water storage cavity through a water pump and a water inlet pipe. After the disinfection is completed, it can also use the water inlet pipe to pump water at the same time to empty the residual liquid in the sterilizer cylinder, effectively solving the problems of residual water accumulation at the bottom of the cylinder and wet sterilization packages. At the same time, an overflow pipe is provided to discharge the liquid exceeding the water level line. However, the inner cylinder of this vertical pressure steam sterilizer is only equipped with a single placement net, which cannot divide the space inside the inner cylinder, and the utilization rate of the space is relatively low.
