[0024] Working principle: First, it is necessary to install between the rotating bottle 8 and the rotator 6, rotate the rotating buckle 506, and drive the linkage rod 505 to rotate through the rotating buckle 506, and drive the linkage bevel gear 504 to rotate through the linkage bevel gear 504, and then drive the rotating bevel gear 503 to rotate through the meshing structure between the linkage bevel gear 504 and the rotating bevel gear 503. Since the rotating bevel gear 503 and the lifting screw rod 502 are fixedly connected, the rotation of the rotating bevel gear 503 can drive the lifting screw rod 502 to rotate. Since the lifting screw rod 502 runs through the interior of the lifting block 507, it drives the lifting screw rod 502 to rotate. The lowering block 507 is lifted and lowered inside the adjusting rail 501, and the position of the rotator 6 is lifted and lowered by the lifting block 507, so that there is enough space between the rotator 6 and the heating pot 702 for installing the rotating bottle 8. After the installation is completed, the rotating bottle 8 is lowered and returned to its original position. According to the optimal heating position between the rotating bottle 8 and the heating pot 702, the rotating sleeve 509 is rotated with the center of the mounting column 508 as the center of the circle. Since the rotating sleeve 509 is fixedly connected to the rotator 6, the rotator 6 is partially rotated, and the angle of the rotator 6 after rotation is fixed by the telescopic spring 510 and the positioning pin 511.
[0025] During the use of the device, the control panel 705 is partially rotated by the amount of water inside the heating pot 702 and the buoyancy of the float 707, and the touch key 706 and the control key 704 are separated. When the amount of water inside the heating pot 702 gradually decreases, the control panel 705 is partially rotated. When the touch key 706 and the control key 704 are in contact, the controller 703 is started, and the lifting cylinder 709 is started by the controller 703, and the position of the push plate 710 is driven to rise by the lifting cylinder 709, so that the water inside the water tank 701 is transported to the inside of the heating pot 702 through the circulation pipe 708, so as to achieve the purpose of timely replenishing the water inside the heating pot 702 and avoid dry burning.
