In order to ensure the safety of agricultural products entering the market, strict testing must be carried out. This involves comprehensive testing and analysis of agricultural products to understand their composition and judge their quality. When conducting agricultural product testing, a key step is to dissolve the agricultural product samples in order to analyze their composition and characteristics in more detail. This process helps to ensure that agricultural products are not affected by potentially harmful substances, thereby ensuring the quality and safety of the final product.

[0003] In this process, a water bath heating device is required to perform preliminary treatment on the test samples. However, the water bath heating devices in the prior art often have low power and slow heating. In addition to being limited by the manufacturing cost and the power limit of the heating device, another important reason is that a high-power heating device will be accompanied by a large amount of water vapor and violent boiling. On the one hand, the water vapor will affect the observation of the experimenters and easily cause steam burns. On the other hand, it will affect the humidity environment in the laboratory, reduce the accuracy of the experimental results, and easily damage the experimental equipment. At the same time, violent boiling can easily cause the experimental vessels in the water bath to shake, affecting the experimental results and easily causing scalding accidents.

[0004] Therefore, it is necessary to develop a water bath heating device that can eliminate the negative effects of high-power heating and quickly heat up. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] The technical problem to be solved by the present invention is that when a water bath 1 using a high-power heating rod 8 is actually used, a large amount of water vapor and violent boiling will cause negative consequences on the experimental results and the safety of experimental operations.

[0023] The utility model provides a water bath heating device for rapid heating, comprising: a water bath box 1, a cup slot 3, a heating rod 8, a temperature controller 9, a water bath cup 2, a water inlet pipe 6 and a drain pipe 7; the bottom of the water bath box 1 is provided with a heating rod 8 and a temperature controller 9 for controlling the power of the heating rod 8 according to preset conditions, the top of the water bath box 1 is provided with a cup slot 3 for accommodating the water bath cup 2, and the side of the water bath box 1 is provided with a water inlet pipe 6 for water inlet and a drain pipe 7 for water discharge; the water bath box 1 is provided with a gas collecting device for collecting water vapor, and the gas collecting device can collect water when the water in the water bath box 1 boils and vaporizes, so as to avoid the water vapor in the water bath box 1 affecting the observation of the experimenter, and at the same time avoid affecting the humidity environment in the laboratory and affecting the experimental results, avoid high-temperature steam from hurting people, and improve the safety of the experiment. When the experimenter observes that water vapor emerges from the gap between the water bath cup 2 and the cup slot 3, the gas collecting device can be manually opened. The amount of water vapor can also be detected by electrical equipment such as a temperature sensor or a humidity sensor to achieve automatic collection of water vapor.

[0024] The gas collecting device includes an annular gas collecting pipe 4, an exhaust pipe 11, and a negative pressure air pump 13; an annular gas collecting pipe 4 is installed on the top wall of the water bath 1, and the annular gas collecting pipe 4 is equidistant from the opening edge of the cup groove 3, and a plurality of gas collecting holes 5 are evenly distributed on the annular gas collecting pipe 4. An exhaust pipe 11 connected to the annular gas collecting pipe 4 is installed on the top wall of the water bath 1, and the other end of the exhaust pipe 11 passes through the water bath 1 and is connected to the negative pressure air pump 13. When in use, the negative pressure air pump 13 is started, a negative pressure is formed in the exhaust pipe 11, and the annular gas collecting pipe 4 is connected to the exhaust pipe 11. At this time, water vapor enters the annular gas collecting pipe 4 from the air collecting holes 5 due to the negative pressure, and is finally discharged from the exhaust pipe 11.

[0025] In a more optimized setting scheme, the gas collecting holes 5 are all opened at the bottom of the annular gas collecting pipe 4 and are all located on the lowest gravitational potential energy surface of the annular gas collecting pipe 4. After the equipment is shut down, the water vapor in the annular gas collecting pipe 4 is liquefied into liquid due to condensation. At this time, these liquids can naturally flow out through the gas collecting holes 5 of the annular gas collecting pipe 4. On the one hand, scale precipitation will not form to block the annular gas collecting pipe 4. On the other hand, the water in the annular gas collecting pipe 4 can be discharged as much as possible, thereby reducing the probability of bacterial reproduction and preventing bacterial reproduction from affecting the experimental environment.

[0026] A spiral cooling pipe 12 is connected between the exhaust pipe 11 and the negative pressure air pump 13, and the axis of the spiral cooling pipe 12 is perpendicular to the ground. After the equipment is shut down, the water vapor in the annular air collecting pipe 4 is liquefied into liquid due to condensation. The axis of the spiral cooling pipe 12 is perpendicular to the ground. The lowest point of the spiral cooling pipe 12 is connected to the negative pressure air pump 13, which can prevent condensed water from being unable to be discharged in the spiral cooling pipe 12. The spiral cooling pipe 12 further increases the heat exchange area of ​​the exhaust pipe 11, so that the water vapor in the exhaust pipe 11 and the spiral cooling pipe 12 is quickly liquefied, avoiding the discharge of water vapor to affect the humidity of the experimental environment, and also improving safety. In some embodiments, a cooling fan can be added to the spiral cooling pipe 12 to further improve the heat exchange efficiency.

[0027] An annular sealing strip 10 is provided on the top of the water bath 1, and the annular sealing strip 10 is equidistant from the opening edge of the cup groove 3. After the water bath cup 2 is placed in the cup groove 3, the annular sealing strip 10 fits with the water bath cup 2 to form a seal. When the negative pressure air pump 13 of the air collecting device is turned on to collect the water vapor in the water bath 1, negative pressure is formed in the water bath 1, and the water bath cup 2 is tightly adsorbed on the water bath 1, so that the boiling water flow is prevented from impacting the water bath cup 2 and causing the water bath cup 2 to vibrate, which affects the accuracy of the experimental results, avoids high-temperature boiling water from spraying out and injuring people, and improves the safety of the experiment.

[0028] The temperature controller 9 is electrically connected to the negative pressure air pump 13 . When the water temperature in the water bath 1 reaches a set temperature, the temperature controller 9 controls the negative pressure air pump 13 to start.

[0029] The spiral cooling tube 12 is made of copper. In order to further quickly liquefy the water vapor in the exhaust pipe 11 and the spiral cooling tube 12, in some embodiments, an aluminum alloy with equally good thermal conductivity may also be used.

[0030] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
