Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, and more specifically to a water bath box that facilitates specimen warm bath and prevents evaporation. Background Art

[0002] Constant temperature water bath boxes are widely used in drying, concentration, distillation, impregnation of chemical reagents, impregnation of drugs and biological preparations, and can also be used for water bath constant temperature heating and other temperature tests. They are essential tools for biology, genetics, virology, aquaculture, environmental protection, medicine, hygiene, biochemical laboratories, analysis rooms, education and scientific research. In the prior art, during experiments, test tubes are usually inserted into a test tube rack and then the test tube rack is placed into the water bath box for heating. In order to avoid hot air leakage affecting the heating efficiency and ensuring the aseptic state inside the water bath box, the water bath box needs to be sealed with a lid. In this way, the following problems will occur. First, since the water bath box is in a sealed state, water vapor will be generated inside after heating. The water vapor will condense on the lid and drip from the lid, which may drip into the test tube and affect the experimental results. Second, after the water bath box is filled with water, the lower parts of the test tubes on the test tube rack are immersed in water, and it is very easy to float upward under the action of buoyancy, resulting in the reagents in the test tubes not being heated, which is also an important factor affecting the experimental results and brings great trouble to the experimenters and needs to be solved urgently. In response to this, the inventor proposes a water bath box that facilitates specimen warm bath and prevents evaporation. By arranging a fastening frame inside the water bath box and a cover body on the lid, the test tubes can be kept stable, and the water vapor will not drip into the test tubes, greatly improving the experimental quality.

[0003] In order to solve the problem of the test tubes floating and becoming unstable during heating, Chinese Patent (Authorization Publication No.: CN220835648U) discloses a water bath box that facilitates specimen placement and removal. The utility model includes a water bath box body and a lifting assembly; the lifting assembly includes a specimen rack, a movable screw, a mounting rack, a main gear, a sub-gear, a movable frame and a driving motor. The mounting rack is fixedly connected to the water bath box body and is located above the water bath box body. The driving motor is fixedly installed inside the mounting rack. The main gear is fixedly connected to the output end of the driving motor. The sub-gear meshes with the main gear. The sub-gear is provided with a threaded hole. The movable screw is threadedly connected to the sub-gear and passes through the threaded hole. The movable frame passes through the mounting rack and its upper and lower ends are respectively fixedly connected to both ends of the movable screw. The specimen rack is rotatably connected to the movable screw. The specimen rack is provided with a plurality of water troughs at intervals. The utility model can fix the EP tubes and is convenient for taking and placing the EP tubes.

[0004] There are still some deficiencies in the application of this solution. Since it is necessary to seal the water bath box with the lid during the experiment to avoid the leakage of hot air affecting the heating efficiency and ensure the aseptic state inside the water bath box, water vapor will condense and drip into the test tube, affecting the experimental results. Also, during the experiment, it is necessary to ensure that the height of the reagent in the test tube is lower than that of the distilled water to ensure that all reagents can be heated, otherwise it will also affect the experimental results. Therefore, it is necessary to improve the structure of the water bath box so that it can prevent the test tube from floating and at the same time prevent water droplets from dripping into the test tube, improving the accuracy of the experimental results and thus enhancing the practicality of the water bath box.
