The spring catch 22 abuts against the side of the connecting frame 19 to fix the position of the connecting frame 19, facilitating the adjustment of the degree of the opening between the connecting frame 19 and the housing 18. After the water temperature is constant, fix the container of the item to be kept at a constant temperature on the fixing clip 17. At least one limit bracket can be installed on the fixing rod 7 to adjust the height of the fixing clip 12, thereby adjusting the distance between the first connecting rod 13 and the water bath kettle body 2. Adjust the position of the adjusting sleeve 14 on the first connecting rod 13 to adjust the position of the lower telescopic rod 15 in the water bath kettle body 2, and adjust the length of the telescopic rod 15 and the angle of the second connecting rod 16, and immerse all of them in the water bath kettle body 2, so that the item to be kept at a constant temperature is heated evenly. The fan starts to extract air from the air guide box 5, creating a negative pressure in the housing 18, thereby absorbing the water vapor at the opening of the water bath kettle body 2 and preventing the water vapor from condensing on the surface of the water bath kettle body 2. When it is necessary to replace the water in the water bath kettle body 2, open the solenoid valve 11, and the waste water enters the water tank 1 through the connecting pipe 10 and is discharged through the drain pipe 4.
