The slip ring drives the lock cylinder, and when the lock cylinder is opened, the upper seal head rotates around the driving shaft under the drive of the rotating arm, so that the door is opened and closed. When the nut gasket is installed, the rectangular spring is compressed, the friction force between the base and the rotating arm is controlled, the effect of applying torque is achieved, and the purpose of stopping the upper end socket at will can be achieved. After the sterilization process of the sterilizer is finished, the temperature is reduced to the uncovering temperature, and at the moment, the tank body is in a sealed micro-negative pressure state. When the rotating arm acts, the driving shaft driving gear is driven to rotate, the driven gear and the driving gear are meshed to rotate, the driving valve is informed to be opened, air enters the sterilization tank body through the tank body connecting pipeline after being filtered by the umbrella-shaped filter, the sealed environment in the tank body is damaged, and smooth opening of the door can be realized. Compare other "door-type" sterilizers from top to bottom, this disclosure forms two-way damping effect through increasing compression spring device when opening and shutting the door about the sterilizer, can not take place the upper cover free fall, produces the operation danger. Most vertical steam sterilizers adopt a vacuum pump form, and the influence that the upper cover cannot be opened by micro negative pressure after sterilization is solved. The vacuum breaking device is combined with the door opening action, realizes the vacuum breaking effect by a pure mechanical structure, increases a filter, and prevents secondary pollution caused by air intake to a sterilized object.
