[0021] Embodiment 1

[0022] The constant temperature water bath device in the prior art is mostly composed of a water tank, a heater, a sensor, a controller, etc. When in use, the reaction container 3 is directly placed in the water tank for water bath heating. If the water bath temperature is high or the reaction container 3 is small in size, it is easy to cause the hot water in the water tank to enter the reaction container 3, which is inconvenient to use. In order to solve this technical defect in the prior art, as Figure 1-Figure 5 As shown, this embodiment proposes a laboratory constant temperature water bath device, which can automatically adjust the height of the storage straight plate 404 according to the volume of the reaction container 3 during the water bath heating process, and can effectively prevent the hot water inside the water bath box 1 from entering the interior of the reaction container 3. The lower end of the water bath box 1 of the water bath device is provided with a water inlet and outlet 2, and the reaction container 3 is placed inside the water bath box 1. The water bath box 1 is provided with a water bath heating mechanism 4 for preventing hot water from entering the reaction container 3, and the upper part of the water bath heating mechanism 4 is provided with a dustproof shielding mechanism 5 for preventing dust from falling into the reaction container 3. After the experimenter puts the reaction container 3 into the water bath box 1, the dustproof shielding mechanism 5 will shield the upper part of the water bath box 1, and at the same time, the water bath heating mechanism 4 will perform water bath heating on the reaction container 3.

[0023] In order to prevent the hot water in the water bath 1 from entering the interior of the reaction vessel 3 and improve the applicability of the device, the present embodiment is provided with a water bath heating mechanism 4 and a dust shielding mechanism 5. Specifically, an electric heater 401 is fixedly installed at the lower end of the water bath 1, and a temperature regulating component 402 for controlling the water temperature is provided on the front of the water bath 1. The temperature regulating component 402 is electrically connected to the electric heater 401 through a wire. Before the water bath heating starts, the experimenter can control the power of the electric heater 401 through the temperature regulating component 402, thereby adjusting the water temperature. The water inside the bathtub 1 is heated, and a side wall groove 403 is symmetrically opened on the inner wall of the water bathtub 1. A storage straight plate 404 is movably installed inside the water bathtub 1. Rectangular protrusions are respectively arranged on both sides of the storage straight plate 404. The rectangular protrusions extend into the inside of the side wall groove 403 and are slidably connected with the side wall groove 403. When the telescopic push rod 406 is extended upward, the rectangular protrusions will move upward along the side wall groove 403. When the rectangular protrusions move upward, the reaction container 3 will move synchronously. The surface of the storage straight plate 404 is penetrated by the opening An elliptical through groove 405 is provided, and a plurality of groups of elliptical through grooves 405 are provided at equal intervals. Clean water in the water bath 1 can freely pass through the elliptical through grooves 405, thereby ensuring that the water temperature inside the water bath 1 is uniform. A telescopic push rod 406 for pushing the storage straight plate 404 upward is provided at the lower end of the inner cavity of the water bath 1. When the storage straight plate 404 moves upward, the reaction container 3 will be moved upward synchronously, thereby adjusting the height difference between the upper edge of the reaction container 3 and the liquid surface. The dustproof shielding structure 5 includes a fixed cover 5 fixedly installed at the upper end of the water bath 1 01, the inner side of the fixed cover shell 501 is rotatably connected with a movable cover shell 502, and a transparent viewing frame 503 is provided on the movable cover shell 502. During the water bath heating process, the experimenter can observe the solution in the reaction container 3 through the transparent viewing frame 503 to avoid overflow. A gripping handle 504 is provided below the transparent viewing frame 503, and the outer sleeve of the gripping handle 504 is provided with a heat insulating sleeve. During the water bath heating process, the experimenter can open the movable cover shell 502 at any time through the gripping handle 504 to facilitate taking the experimental solution.

[0024] In this embodiment, when the experimenter needs to heat the reaction solution in a water bath, the temperature control component 402 is first used to quickly preheat the clean water in the water bath box 1. After the preheating is completed, the experimenter uses the grip handle 504 to push the movable cover 502 upward, and then places the reaction container 3 containing the reaction solution on top of the storage straight plate 404.

[0025] Next, the experimenter will adjust the telescopic push rod 406 according to the volume of the reaction container 3. When the telescopic push rod 406 is extended upward, the reaction container 3 and the storage straight plate 404 will move upward synchronously, thereby adjusting the height of the upper edge of the reaction container 3 from the water, which can effectively prevent the hot water in the water bath 1 from entering the interior of the reaction container 3 during the heating process.

[0026] Moreover, after the water bath heating is completed, the experimenter can also move the reaction container 3 out of the hot water by adjusting the telescopic push rod 406, which is convenient for the experimenter to take and can effectively avoid scalding.

[0027] In addition, after the experimenter places the reaction container 3 into the water bath 1, he will pull down the movable cover 502 to shield the top of the water bath 1. If it is necessary to observe the color change of the reaction solution, it can be observed through the transparent viewing frame 503 without opening the movable cover 502, which can effectively prevent impurities such as dust in the air from falling into the interior of the reaction container 3 and causing pollution.

[0028] This embodiment provides a water bath heating mechanism 4, and utilizes the mutual cooperation between the storage straight plate 404 and the side wall slide groove 403. During the water bath heating process, the height of the storage straight plate 404 can be automatically adjusted according to the volume of the reaction container 3, thereby preventing the hot water inside the water bath box 1 from entering the interior of the reaction container 3, and is suitable for a variety of reaction containers 3 of different volumes; moreover, this embodiment provides a dustproof shielding mechanism 5, and utilizes the mutual cooperation between the movable cover shell 502 and the transparent viewing frame 503. During the water bath heating process, the top of the water bath box 1 can be automatically shielded, and the observation of the physical changes of the reaction solution by the experimenter will not be affected, and dust in the air can be effectively prevented from entering the interior of the reaction container 3.

[0029] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
