Description

Technical Field

[0001] This utility model relates to the field of sterilizer technology, and more specifically, to a steam sterilizer. Background Technology

[0002] Steam sterilizers utilize the high temperature and high humidity characteristics of saturated steam under high temperature and high pressure to denature and coagulate the microbial proteins on the surface of the items to be sterilized, making them irreversible and thus achieving sterilization. Most current steam sterilizers require adding distilled water inside before sterilization, but during the heating process, the distilled water inside boils away and needs to be added externally and reheated, making the operation cumbersome. For example, the patent with prior art announcement number CN218338715U discloses a vertical steam sterilizer. After sterilization, the sealing cover assembly is rotated counterclockwise to open the sterilization chamber. As the sealing cover assembly rotates, it drives the rotating column to rotate. The rotating column drives the transmission rod to move downward and pushes the second piston. The second piston pushes the first piston upward through the transmission medium, so that the linkage rod and the moving block drive the tray out of the sterilization chamber and expose it to the air for rapid cooling. The staff can quickly remove the tray through the opening, reducing contact with the inner wall of the sterilizer, reducing the risk of burns, and making it more convenient to pick up and put down the tray.

[0003] When the above-mentioned device is in operation, it can make the tray rise and fall vertically and pass through the sterilizer body, exposing it to the outside air for rapid cooling. This not only makes it convenient for staff to pick up and put down the tray, but also reduces the chance of staff coming into contact with the inner wall of the sterilizer body, reducing the risk of burns. However, when the piston moves upward, the transmission medium it receives cannot be controlled, which makes the stability of the moving block pressing against the tray movement worse, making it inconvenient for staff to remove the tray. At the same time, the high-temperature steam inside the sterilizer will also leak out from the piston, thus reducing the efficiency and effect of sterilization. Utility Model Content
