[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0027] Embodiment 1: As Figures 1-5 shown, the present invention provides a constant temperature water bath pot with uniform heating, including a main body 1 of the water bath pot. Two mounting frames 5 are fixedly installed on the outer surface wall of the main body 1 of the water bath pot. A movable frame 6 is movably inserted between the inner surface walls of the two mounting frames 5. Two limit rods 7 are movably inserted into the inner surface wall of the movable frame 6. A water storage tank 8 is opened at the top of the main body 1 of the water bath pot. A support shaft 9 is movably inserted into the inner surface wall of the main body 1 of the water bath pot. A placing rack 10 is fixedly sleeved on the outer surface wall of the support shaft 9. A placing plate 14 is arranged on the inner surface wall of the placing rack 10. An annular groove 15 is opened at the top of the placing plate 14. A connecting shaft 16 is arranged on the inner surface wall of the annular groove 15, and the top of the connecting shaft 16 is fixedly connected to the outer wall side of the movable frame 6.

[0028] The effect achieved by the entire Embodiment 1 is that when it is necessary to heat the substances inside the test tube, first, under the operation of the staff, the limiting rod 7 is taken out and the movable frame 6 is moved downward inside the mounting frame 5. Under the action of the connecting shaft 16, the placement plate 14 is driven to move to a suitable position. Then, the limiting rod 7 is inserted between the inner walls of the mounting frame 5 and the movable frame 6 to fix and limit it. Subsequently, the test tube containing the substances is inserted into the notches formed on the outer walls of the placement rack 10 and the placement plate 14. Then, hot water is delivered into the water storage tank 8 to heat the substances inside the test tube. When the heating inside the test tube is completed, under the operation of the staff, the limiting rod 7 is taken out so that it no longer limits the mounting frame 5 and the movable frame 6. Subsequently, under the operation of the staff, the movable frame 6 is moved upward inside the mounting frame 5. At the same time, under the action of the connecting shaft 16, the placement plate 14 is driven to move upward. Since the notch formed on one side of the outer wall of the placement plate 14 is not a through-notch, the upward movement of the placement plate 14 can drive the test tube to move upward, thereby taking the test tube out of the hot water, preventing the staff's hands from directly contacting the heated test tube, and thus protecting the staff's hands from being injured by high temperature.

[0029] Embodiment 2: As Figures 2-5As shown in the figure, a first gear 11 is fixedly sleeved on the outer surface wall of the support shaft 9. The bottom of the inner wall of the water bath main body 1 is fixedly installed with a motor 12. The output end of the motor 12 is fixedly sleeved with a second gear 13. The outer surface wall of the second gear 13 is meshed and connected with the outer surface wall of the first gear 11. An installation groove 17 is opened at the top of the water bath main body 1. The inner wall of the installation groove 17 is provided with a top plate 18. Two fixing grooves 19 are opened at the top of the top plate 18. The inner surface walls of the two fixing grooves 19 are both movably embedded with limit plates 20. The inner surface walls of the two fixing grooves 19 are both provided with two limit springs 21, and one side of the outer wall of the limit spring 21 is fixedly connected with one side of the outer wall of the limit plate 20. The bottom of the inner wall of the installation groove 17 is fixedly installed with a water storage tank 22. The top of the water storage tank 22 is fixedly communicated with a temperature sensor 23. A water injection port 24 is arranged at the top of the water storage tank 22. One side of the outer wall of the water storage tank 22 is fixedly communicated with a water delivery pipe 25, and the outer surface wall of the water delivery pipe 25 is fixedly communicated with the inner surface wall of the water storage groove 8. The bottom of the inner wall of the installation groove 17 is fixedly installed with a water pump 26, and the outer surface wall of the water pump 26 is fixedly communicated with the outer surface wall of the water delivery pipe 25. One side of the outer wall of the water storage tank 22 is fixedly communicated with a return pipe 27, and the outer surface wall of the return pipe 27 is fixedly communicated with the inner surface wall of the water storage groove 8. The bottom of the inner wall of the installation groove 17 is fixedly installed with a power supply 28. A heating pipe 29 is arranged on the inner surface wall of the water storage tank 22, and the outer surface wall of the heating pipe 29 is electrically connected with the outer surface wall of the power supply 28. One side of the outer wall of the water storage tank 22 is fixedly communicated with a drain pipe 30. Valves 31 are arranged inside both the drain pipe 30 and the return pipe 27. Four support feet 2 are fixedly installed at the bottom of the water bath main body 1. Two embedding grooves 3 are opened at the top of the water bath main body 1. Two top covers 4 are movably embedded between the inner surface walls of the two embedding grooves 3.

[0030] The effect achieved by the entire Embodiment 2 is that after the test tube is placed, the top cover 4 inside the embedded groove 3 is moved to close it, and at the same time the valve 31 is closed. Then the limit plate 20 is pressed so that it no longer plays a role in fixing and limiting the top plate 18, and the top plate 18 is disassembled. Water is injected into the water storage tank 22 from the water injection port 24. Subsequently, under the action of the limit spring 21 and the limit plate 20, the top plate 18 is installed. And under the action of the power supply 28 and the heating tube 29, the water inside the water storage tank 22 can be heated. At the same time, under the action of the temperature sensor 23, the controller and other structures, the temperature of the water inside the water storage tank 22 can be controlled to keep it within a stable range. When the temperature of the water inside the water storage tank 22 reaches an appropriate value, under the action of the water pump 26 and the water delivery pipe 25, the heated water is delivered into the water storage tank 8. At the same time, the valve 31 inside the return pipe 27 is opened so that the water inside the water storage tank 8 and the water storage tank 22 can circulate. When the hot water enters the water storage tank 8 to heat the test tube, under the action of the motor 12, the second gear 13 is driven to rotate. At the same time, under the action of the first gear 11, the support shaft 9 is driven to rotate, thereby driving the placement rack 10 and the test tube to rotate, so that the test tube can fully contact the hot water, improving the uniformity of heating the substances inside the test tube, and thus improving the heating effect of the substances.

[0031] Working principle: When it is necessary to heat the substances inside the test tube using a constant temperature water bath, first move the top cover 4 inside the embedded groove 3 to open it. Then, under the operation of the staff, take out the limit rod 7 and move the movable frame 6 downward inside the mounting frame 5. Under the action of the connecting shaft 16, drive the placement plate 14 to move to a suitable position. Then insert the limit rod 7 between the inner walls of the mounting frame 5 and the movable frame 6 to fix and limit it. Subsequently, insert the test tube containing the substances into the notches opened on the outer walls of the placement rack 10 and the placement plate 14. Then close the top cover 4 and at the same time close the valve 31. Then press the limit plate 20 so that it no longer fixes and limits the top plate 18, disassemble the top plate 18, and inject water into the water storage tank 22 from the water injection port 24. Subsequently, under the action of the limit spring 21 and the limit plate 20, install the top plate 18. And under the action of the power supply 28 and the heating tube 29, the water inside the water storage tank 22 can be heated. At the same time, under the action of the temperature sensor 23, the controller and other structures, the temperature of the water inside the water storage tank 22 can be controlled to keep it within a stable range. When the temperature of the water inside the water storage tank 22 reaches a suitable value, under the action of the water pump 26 and the water delivery pipe 25, the heated water is transported into the water storage tank 8. At the same time, open the valve 31 inside the return pipe 27 so that the water inside the water storage tank 8 and the water storage tank 22 can circulate. When the hot water enters the water storage tank 8 to heat the test tube, under the action of the motor 12, drive the second gear 13 to rotate. At the same time, under the action of the first gear 11, drive the support shaft 9 to rotate. And under the action of the annular groove 15, the connecting shaft 16 will not interfere with the rotation of the placement rack 10 and the test tube, so that the test tube can fully contact the hot water and heat the substances inside the test tube. When the substances inside the test tube are heated, under the operation of the staff, take out the limit rod 7 so that it no longer limits the mounting frame 5 and the movable frame 6. Subsequently, under the operation of the staff, move the movable frame 6 upward inside the mounting frame 5. At the same time, under the action of the connecting shaft 16, drive the placement plate 14 upward. Since the notch opened on one side of the outer wall of the placement plate 14 is not a through notch, the upward movement of the placement plate 14 can drive the test tube upward, thus taking the test tube out of the hot water. When it is necessary to replace the heating water, open the valve 31, and under the action of the drain pipe 30, the water can be drained for replacement.

[0032] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
