[0029] Working principle: first, hold the hollow piston 17 with your hand, and then pull the pull rod 19, and then the pull rod 19 pulls the diamond block 25 through the steel rope 26 to shrink, and then take out the hollow piston 17, and then pour water into the hollow frame 1 from the water inlet 3, and then insert the hollow piston 17 into the water inlet 3, the diamond block 25 will be squeezed into the cross slide 18, and then when the hollow piston 17 is inserted, the diamond block 25 will be pushed by the fourth reset spring 29 to reset and clamp the inner wall of the hollow frame 1, and then turn on the heating plate 4 to heat the water. After heating for a period of time, the hot air will be transmitted from the hollow rotating rod 6 to the hollow shutter 7, and then After that, the air pressure will push the arc scraper 10 to expand to both sides. At this time, the air pressure will also be transmitted into the L-shaped air blocking plate 30 and the pressure-bearing pipe 33 through the baffle of the L-shaped partition plate 5, and then the air pressure will push the circular piston 35 to move backward. When the air pressure reaches a certain pressure, the circular piston 35 will move to the place where the exhaust pipe 42 and the pressure-bearing pipe 33 are connected to release the pressure, and then slide the switch block 61 above, and then drive the three-head support rod 43, and the three-head support rod 43 will drive the movable block 41 and the silicone baffle 40 to open the closed exhaust hole 37, and then the air pressure will push the square piston 46 from the air supply square tube 44. At this time, the pressure is slightly reduced and the arc scraper 10 will pass. The first return spring 11 rebounds and slides inward to slightly squeeze the air pressure, and then the auxiliary air pressure pushes the square piston 46, and then the square piston 46 drives the rack 47, and then the rack 47 will push the large gear 57 to rotate, and then the large gear 57 drives the fourth pulley 58 to rotate through the third rotating shaft 56, and then the fourth pulley 58 drives the third pulley 55, the second bevel gear 54, and the second rotating shaft 53 to rotate through the fourth belt 59, and then the second bevel gear 54 drives the first bevel gear 52 to rotate, and then the first bevel gear 52 drives the second pulley 50 to rotate through the first rotating shaft 49, and then the second pulley 50 drives the fourth pulley 55 through the first belt 51. The pulley 58 rotates, and then the first pulley 48 drives the hollow rotating rod 6, and then the hollow rotating rod 6 drives the closed hollow shutter 7 to open, and then when the shutter is opened for a period of time, the upper switch block 61 is slid in the opposite direction again, and then the switch block 61 drives the three-head support rod 43, the movable block 41, and the silicone baffle 40 to close the exhaust hole 37, and then the mirrored structure on the other side will open, and repeat some of the above steps to close the hollow shutter 7. When the shutter is not opened or closed with air pressure, the lower switch block 61 can be slid, and then the switch block 61 drives the transmission rod 60, and the transmission rod 60 drives the rack 47 to open and close the device to complete the work.
