Description

Technical Field

[0001] The present application relates to high pressure steam sterilizers. Background Art

[0002] High-pressure steam sterilizer is a device that uses saturated pressure steam to sterilize items quickly and reliably. It is suitable for medical, scientific research, agriculture and other units. High-pressure steam sterilizers are divided into portable high-pressure steam sterilizers, vertical high-pressure steam sterilizers, horizontal high-pressure steam sterilizers, etc. according to style and size. When conducting environmental testing, water quality testing or soil testing, high-pressure steam sterilizers are needed to sterilize some testing tools.

[0003] During sterilization, the objects to be sterilized are generally placed directly in the sterilization box of the high-pressure steam sterilizer. If there are many objects to be sterilized, the objects will be crowded or even stacked, resulting in a poor sterilization effect. When taking out the sterilized objects, the staff generally directly reaches into the sterilizer to take out the objects in the sterilizer. However, since the sterilization box is deep, it is inconvenient for the staff to take the objects.

[0004] Therefore, it is desirable to provide a high pressure steam sterilizer. Summary of the invention
