[0041] Working principle: We put the packaged thick-burned jade on the inner wall of the filter 13, and then confine all the packaged thick-burned jade inside the fixed frame 12 through the sealing plate 14, blow steam into the interior of the sterilization box 1 through the air inlet pipe 3, and then drive the rotating shaft 6 to rotate through the driving motor 5, thereby driving the driving wheel 7 to rotate, and through the friction force, the driving wheel 7 can drive the belt 8 to rotate, so that the belt 8 can transmit the force to the two driven wheels 10, and the two driven wheels 10 respectively drive a plurality of connecting blocks 11 to rotate, thereby driving the fixed frame 12 fixed with the connecting blocks 11 to rotate, so that the upper and lower surfaces of the packaged thick-burned jade inside the fixed frame 12 can be evenly heated by steam for a long time for sterilization. After the sterilization is completed, the sealing plate 14 is opened, and then the ring 17 is held to apply tension, and then the sliding rod 16 is driven to slide, thereby driving the sliding plate 15 to slide and package The loaded thick-burned jade is taken out, and during the steam heating and sterilization process, steam will adhere to the inner wall of the sterilization box 1. At this time, the driving wheel 7 will drive the eccentric wheel 21 to rotate, so that the eccentric wheel 21 can drive the force-bearing plate 22 to slide when rotating, thereby driving the right-angle column 23 to slide, and then the right-angle column 23 drives the connecting column 24 to slide inside the fixed cylinder 25, and the fixed cylinder 25 will also drive the circular plate 35 to slide. During the sliding process, the circular plate 35 will also squeeze the spring 1 26, so that the spring 1 26 can store elastic potential energy, and then give the circular plate 35 a reverse force, and the reverse force received by the circular plate 35 will push the connecting rod 27 to slide, thereby driving the rubber head 28 to slide and knock the striking plate 29, so that the striking plate 29 transmits the vibration force to the inner wall of the sterilization box 1, so that the water droplets inside the sterilization box 1 can quickly fall to the bottom end of the sterilization box 1 for storage and circulation;

[0042] When the air intake pipe 3 is blowing into the whole, it will push the ball 31 to slide, thereby driving the support plate 32 to slide on the inner wall of the air intake pipe 3 and the outside of the fixed shaft 33. Then, the support plate 32 will squeeze the spring 2 34 during the sliding process, so that the spring 2 34 can store elastic potential energy, and then give the ball 31 an opposite force, so that after the transportation of steam is stopped, the ball 31 can quickly return to its original position and fit tightly with the disc 30, thereby avoiding the situation of steam reflux.
