At the upper end of the water bath pot 1, there is a cover plate 12. At the upper end of the cover plate 12, there is an observation window 10. When using the constant temperature water bath device to heat an object inside the laboratory, add water into the water bath pot 1, then place the object on the partition 5, and then close the cover plate 12 with the observation window 10. By timing and matching with the temperature controller 6, the heating elements 3 on the heating plate 2 are controlled. Then, the heating elements 3 on the heating plate 2 heat the water in the water bath pot 1. Then, the object on the partition 5 is heated by the heat of the water. And the electric telescopic rod 4 enables the partition 5 to move, so that the bottom of the partition 5 always maintains an appropriate distance from the water surface. At this time, the dry burning prevention sensor 7 and the low water level automatic protector 8 improve the safety of using the water bath pot 1. By changing the position of the partition 5 inside the water bath pot 1, the partition 5 can always maintain an appropriate distance from the water surface, so that the object on the partition 5 can be constantly and stably heated at a constant temperature, improving the heating efficiency and temperature control accuracy.

[0029] Refer to Figures 1-4As shown, this embodiment discloses that a limit device 11 is provided at the lower end of the inner wall of the partition 5, and the limit device 11 includes a slide rail 1101, the slide rail 1101 is fixedly connected to the partition 5, the slide rail 1101 is internally slidably connected with a sliding block 1102, one side of several sliding blocks 1102 is fixedly connected to a limit plate 1103, one side of the sliding block 1102 is inserted with a clamping block 1104, one side of the slide rail 1101 is fixedly connected to a disc 1105, one side of the disc 1105 is circumferentially opened with several through holes 1106, and the clamping block 1104 is clamped with the through holes 1106 on one side of the disc 1105. When multiple objects are placed inside the partition 5 for heating, the objects can be placed on multiple limit plates 1103 for separation and limitation to prevent the objects from tipping over. When the objects are large in size, the block 1104 is moved to disengage the block 1104 from the through hole 1106 on one side of the disc 1105, and then the limit plate 1103 is moved to allow the sliding block 1102 to slide inside the slide rail 1101, and then the spacing of the limit plates 1103 is changed. Then the block 1104 is moved to allow the block 1104 to pass through the sliding block 1102 and reach the through hole 1106 on one side of the disc 1105 to fix the limit plate 1103, and then the larger objects are blocked and limited. By using the limit device 11, multiple objects on the partition 5 can be separated and the objects can be blocked and limited to prevent the objects on the partition 5 from tipping over due to force, so that the objects can be placed more stably on the partition 5 for heating, thereby improving the use effect of the constant temperature water bath device.

By using a limit plate 1103 with adapted size, the object on the partition 5 can be better blocked and limited. One side of the limit plate 1103 is fixedly connected with a plurality of anti-sliding blocks 1107, and the plurality of anti-sliding blocks 1107 are equidistantly arranged on one side of the limit plate 1103. By using the anti-sliding blocks 1107, the friction between the limit plate 1103 and the operator is increased, so that the limit plate 1103 can be moved more easily. Rubber pads 1108 are fixedly connected to both sides of the limit plate 1103, and the size of the rubber pads 1108 is adapted to the size of the limit plate 1103.

By using the connecting rope 1112, the clamping block 1104 is connected to the sliding block 1102 to prevent the clamping block 1104 from being lost.

[0032] Working principle: When using a constant temperature water bath device to heat an object inside a laboratory, water is added to the water bath pot 1, and then the object is placed on the partition 5. Then, the cover plate 12 with the observation window 10 is closed. By timing and fitting with the temperature controller 6, the heating element 3 on the heating plate 2 is controlled. Then, the heating element 3 on the heating plate 2 heats the water in the water bath pot 1. Then, the object on the partition 5 is heated by the heat of the water. And the electric telescopic rod 4 enables the partition 5 to move, so that the bottom of the partition 5 always maintains an appropriate distance from the water surface. At this time, the dry-burning prevention sensor 7 and the low water level automatic protector 8 improve the safety of using the water bath pot 1. By changing the position of the partition 5 inside the water bath pot 1, the partition 5 can always maintain an appropriate distance from the water surface, so that the object on the partition 5 can be continuously and stably heated at a constant temperature, improving the heating efficiency and temperature control accuracy. The design of the observation window 10 facilitates the experimenter to monitor the experiment process in real time, enhancing the safety and reliability of the experiment. The application of the temperature controller 6 ensures the stability and accuracy of the water temperature. The use of the dry-burning prevention sensor 7 and the low water level automatic protector 8 further improves the safety performance of the constant temperature water bath device.

[0033] When heating multiple objects placed inside the partition plate 5, the objects can be placed at multiple limit plates 1103 for separation and limitation to prevent the objects from tipping over. When the size of the object is relatively large, move the clamping block 1104 to make the clamping block 1104 disengage from the through hole 1106 on one side of the disc 1105, and then move the limit plate 1103 to make the sliding block 1102 slide inside the slide rail 1101, and then complete the change of the distance between the limit plates 1103. Then move the clamping block 1104 to make the clamping block 1104 pass through the sliding block 1102 and reach the inside of the through hole 1106 on one side of the disc 1105 to fix the limit plate 1103. Then, block and limit the object with a relatively large size. By using the limiting device 11, multiple objects on the partition plate 5 can be separated, and the objects can be blocked and limited to prevent the objects on the partition plate 5 from tipping over due to force, so that the objects can be placed more stably on the partition plate 5 for heating, thereby improving the use effect of the constant temperature water bath device.
