[0026] like Figure 2 and Figure 4 As shown in the figure, a measuring groove 10 is provided on the side wall of the heating groove 2, a lifting screw 11 is screwed on the top of the measuring groove 10, a handle block 12 is fixedly installed on the top of the lifting screw 11, and the lifting screw 11 is conveniently rotated by the handle block 12, and a mounting block 13 is rotatably connected to the bottom of the lifting screw 11, and the mounting block 13 is adapted to the size of the measuring groove 10, and the mounting block 13 is slidably connected in the measuring groove 10, and the height position of the mounting block 13 can be adjusted in the measuring groove 10 by rotating the lifting screw 11, and a liquid level detection sensor 14 is fixedly installed on the side wall of the mounting block 13, and the liquid level detection sensor 14 is electrically connected to the controller in the device body 1 through a waterproof wire, and when the liquid level in the heating groove 2 reaches the position of the liquid level detection sensor 14, the liquid level detection sensor 14 sends an electrical signal to the controller, so that the controller closes the first solenoid valve 5, and the height position of the liquid level detection sensor 14 is adjusted by the height position of the mounting block 13, so as to control the amount of water added to the heating groove 2.

[0027] Working principle: During the use of the device, the height positions of the mounting block 13 and the liquid level detection sensor 14 are first adjusted by screwing the lifting screw 11 according to the heating requirements, so that the liquid level detection sensor 14 is located at the specified liquid level height required during the heating process, and then the fixing frame 4 is assembled into the heating tank 2 through the handle frame 45, and the device is turned on. First, the controller in the device body 1 controls the first solenoid valve 5 to open and the second solenoid valve 6 to close, and water is added to the heating tank 2 from the external water supply pipe. When the liquid level reaches the height position of the liquid level detection sensor 14, the liquid level detection sensor 14 sends an electrical signal to the controller, so that the controller controls the first solenoid valve 5 to close, so that the water in the heating tank 2 reaches the specified liquid level height, and then controls The device controls the disk heater 32 to turn on and heat the temperature to the specified temperature, and at the same time controls the air pump 94 to turn on. In the process of heating the water through the disk heater 32, the air pump 94 introduces bubbles into the heating tank 2. The disturbance of the water in the heating tank 2 by the bubbles can accelerate the heating of the water and make the temperature distribution of the water at each position more uniform. After reaching the specified heating temperature, the cover 44 is opened, and the experimental equipment that needs to be heated in a water bath is placed in the fixed cylinder 42, and the water bath heating operation is performed on the experimental equipment. When the water bath heating is completed, the experimental equipment is taken out of the fixed cylinder 42, and then the air pump 94 and the disk heater 32 are turned off, and the second solenoid valve 6 is opened, and the water in the heating tank 2 is discharged to the outside through the second solenoid valve 6.
