Description

Technical Field

[0001] The utility model belongs to the technical field of experimental equipment, and particularly relates to a water bath pot which can automatically replenish water and continuously boil. Background Art

[0002] At present, the water baths on the market will usually evaporate the water in the bath gradually as the heating progresses. Especially for some experiments with long reaction times, it is necessary to manually replenish water in the bath to avoid interruption of the experiment caused by the lowering of the water level. At the same time, when more experimental containers (such as conical flasks) are placed, the evaporation consumption of boiling water in the bath increases, requiring operators to monitor the water level at all times and frequently replenish water.

[0003] However, since artificial water replenishment usually adds water close to room temperature, which has a large temperature difference with the boiling water in the bath, the water temperature in the bath will drop sharply during the addition process, especially when the amount of water added is large, it is very easy to cause the boiling of the water bath to be interrupted. At this time, it is necessary to reheat and wait for boiling, and even cause the experiment to be interrupted, which seriously affects the normal progress of the experiment. In addition, the process of adding water is very likely to cause uneven water temperature in the bath and inconsistent water temperature in different places. For example, the water temperature at the water replenishment location is low, and the constant temperature environment conditions of the experiment cannot be effectively guaranteed, which seriously affects the accuracy and reliability of the experimental test results.

[0004] Therefore, it is necessary to design a water bath that can automatically replenish water, keep the liquid level stable, boil continuously, and ensure constant temperature heating environment conditions. Summary of the invention

[0039] In order to enable those skilled in the art to better understand the present invention, the present invention is now further described in conjunction with specific implementation methods.

[0040] Embodiment 1:

[0041] like Figure 1 to Figure 8 As shown, the utility model provides a water bath pot which can automatically replenish water and boil continuously, comprising an upper cylinder 1, a lower cylinder seat 2, a water replenishment core sleeve 3, a driving unit 4 and a control unit 5, wherein six water bath cylinders 11 evenly spaced along the circumferential direction are arranged inside the upper cylinder 1, a water storage cylinder 21 coaxially arranged therewith is arranged at the center of the lower cylinder seat 2, the water replenishment core sleeve 3 is arranged inside the upper cylinder 1 and movably sleeved on the six water bath cylinders 11 and the outer periphery of the water storage cylinder 21.

The upper cylinder 1 is mounted above the lower cylinder seat 2 and is fixedly connected thereto. The water storage cylinder 21 is also a cylindrical structure with an opening on the top. It penetrates the upper cylinder 1 and extends upward out of the upper opening of the upper cylinder 1. In special circumstances, water can be added into the water storage cylinder 21 through the upper opening to ensure sufficient water supply.

[0044] like Figure 3 , Figure 5 As shown, the bottom wall of the water bath 11 is provided with a water replenishment port 111, and the water replenishment core sleeve 3 is provided with six water supply ports 31 corresponding to the water bath 11, and each water supply port 31 is respectively connected to the corresponding water replenishment port 111 of the water bath 11 through the water replenishment flexible pipe 6, so that the water bath 11 and the water replenishment core sleeve 3 form a communicating vessel structure, so that the liquid level of the water replenishment core sleeve 3 and the water bath 11 is always consistent. Specifically, as Figure 5 The bottom wall of the upper cylinder 1 is shown to be provided with a through hole matching the diameter of the water replenishment flexible tube 6. One end of the water replenishment flexible tube 6 is fixedly connected to the water replenishment port 111 of the bottom wall of the water bath 11, and the other end passes through the through hole of the bottom wall of the upper cylinder 1 and is fixedly connected to the water supply port 31 of the bottom wall of the water replenishment core sleeve 3. The water replenishment flexible tube 6 can be bent and extended to ensure that the water replenishment core sleeve 3 can still maintain communication with the water bath 11 during the lifting process.

[0045] Furthermore, each of the six water replenishment flexible pipes 6 is provided with a water replenishment opening and closing valve (not shown in the figure), and the water replenishment opening and closing valve is connected to the control unit 5 to control the on and off of the water replenishment flexible pipe 6, thereby achieving the effect of independent control of the six water baths 11, such as the water replenishment opening and closing valve of one water bath 11 can be opened separately to realize a single independent experiment, or the water replenishment opening and closing valves of the six water baths 11 are all opened to realize the simultaneous conduct of multiple batches of experiments.

The water replenishment heating unit 33 can preheat the water stored in the water replenishment core sleeve 3, such as heating it to about 95°C. In this way, when the water stored in the water replenishment core sleeve 3 is used to replenish water to the water bath 11, the boiling will not be stopped due to a large temperature difference or a sudden drop in temperature, thereby achieving continuous and uninterrupted boiling of the water in the water bath pot, providing a stable and constant temperature heating environment condition for the experiment.

[0049] The water supply flexible pipe 7 is provided with a water supply opening and closing valve and a water supply pump (not shown in the figure), which are both connected to the control unit 5. The water supply pump can pump the water inside the water storage cylinder 21 into the water replenishment core sleeve 3 when the liquid level in the water replenishment core sleeve 3 or the water storage cylinder 21 is low.
