Description

Technical Field

[0001] This utility model relates to the field of sealing door technology, specifically a sealing door for a pulsed vacuum sterilizer. Background Technology

[0002] A pulsed vacuum sterilizer is an instrument used for steam sterilization of hollow items and utensils. Its principle is based on the physical property that saturated steam releases a large amount of latent heat during condensation, placing the items to be sterilized in a high-temperature and humid state. After a period of heat preservation, sterilization is achieved. It is widely used in the sterilization of fabrics and medicines, and can also be used in the pharmaceutical industry for the production of sanitary materials, dressings, and instruments. However, in existing pulsed vacuum sterilizers, steam adheres to the sealed door, forming water droplets that obstruct the view, preventing staff from observing the interior of the sterilizer in a timely manner.

[0003] The patent with publication number CN218797533U describes a sealing door for a pulsating vacuum sterilizer, which includes a cylinder, a movable groove, a connecting block, and a sponge block. During use, the cylinder is activated to move the connecting block in the movable groove, which in turn moves the chamber, which in turn moves the sponge block. The sponge block then comes into contact with the door and window, which can promptly wipe away water droplets adhering to the door and window, preventing water droplets from obstructing the view and allowing staff to easily observe the internal conditions of the pulsating vacuum sterilizer through the door and window.

[0004] However, this sealing door has shortcomings in use. Before and after disinfection, the sealing door needs to be opened to insert or remove components into the cavity. However, existing sealing doors often use a hinge structure. To ensure the sealing effect, the sealing door is often quite heavy. This results in the hinge joint being subjected to a large force during opening and closing, which can generate a lot of noise and even cause the hinge to break after long-term use.

[0005] Based on this, a pulsating vacuum sterilizer sealing door is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
