A door 111 is installed on the sterilization chamber 110, and the door 111 is used to open or close the sterilization chamber 110. The bottom of the side plate installed in front of the frame 100 is provided with an installation cavity, and the installation cavity is internally provided with a pedal device 150 and an anti-false touch assembly 170. The door 111 is provided with an electric push rod 113, the lower end of the electric push rod 113 is connected with the frame 100, and the upper end of the electric push rod 113 is connected with the door 111, so that the electric push rod 113 is guided and fixed.

When the second detecting device 117 can detect the position of the door 111, the second detecting device 117 outputs an OFF signal to the control system, the first detecting device 115 outputs an ON signal to the control system, the pedal device 150 is stepped ON, the pedal device 150 outputs an ON signal to the control system, the control system sends a forward rotation instruction ON to the electric push rod 113, the electric push rod 113 starts to rotate forward, and the door 111 moves upward, and at this time, the second detecting device 117 outputs an ON signal to the control system. When the door 111 moves to the highest level, the first detecting device 115 outputs an OFF signal to the control system, and the control system issues a forward rotation command OFF to the electric putter 113, and the electric putter 113 stops rotating forward and the door 111 stops moving.
When the door 111 is moving up or down, the first detecting device 115 outputs an ON signal to the control system, and the second detecting device 117 outputs an ON signal to the control system. The pedal device 150 is stepped down, the pedal device 150 outputs an ON signal to the control system, when the cabin door 111 is moving upwards, the control system sends a forward rotation instruction Off and a reverse rotation instruction ON to the electric push rod 113, the electric push rod 113 starts to rotate reversely, the cabin door 111 moves downwards, when the cabin door 111 is limited downwards, the second detection device 117 outputs an Off signal to the control system, the control system sends a reverse rotation instruction Off to the electric push rod 113, the electric push rod 113 stops rotating reversely, and the cabin door 111 stops moving; when the door 111 is moving downward, the control system issues a reverse instruction Off to the electric pushrod 113, the electric pushrod 113 stops the reverse rotation, and the door 111 stops moving.
