Problems solved by technology
However, the height of the existing physical experiment table is fixed and cannot be adjusted according to the height of the students, which affects the students' experimental operation and increases the difficulty of the experiment; in addition, in the physical experiment, it is often necessary to do various heating experiments. During experiments, it is usually necessary to use a heating frame, which can support the alcohol lamp and the object to be heated, but the heating frame in the prior art is a simple iron frame, and it is inconvenient to adjust the heating position of the alcohol lamp. Therefore, the outer flame of the alcohol lamp cannot be well used for heating, and the heating efficiency is relatively low. At the same time, it is difficult to flexibly adjust the distance between the flame of the alcohol lamp and the flask to be heated, especially when the boiling point and pressure of the liquid are determined. During the experimental operation, there is a lack of devices that can flexibly adjust the height of each component

The invention discloses a heating device for boiling point and pressure experiments in high school physics. The heating device comprises an experiment table with an adjustable height, a flask supportassembly and an alcohol lamp assembly, the heights of the formed experiment table, the flask support assembly and the alcohol lamp assembly are all adjustable, elevation or decrease of the height of atable surface of the experiment table is driven under the driving of a second servo motor so that the height of the experiment table surface can be adjusted, the overall height of the flask support assembly can be adjusted driven by a first servo motor, the distance between a pump and a flask is adjusted by employing sliding of a first elevating sliding sleeve and a second elevating sliding sleeve on an elevation column, the heights of a support rack and the alcohol lamp are adjusted through rotation of an adjusting handle and an elevation screw rod to adjust the distance between the alcohollamp and the flask, the heating intensity of flames of the alcohol lamp on the flask is adjusted, and the cooperation of different pressures blown into the flask by an increase pump is also provided so that experiments of the influence on the boiling point of sample liquid in the flask by pressures and heating temperatures can be realized.
Description
technical field [0001] The invention relates to the technical field of high school physics experiments, more specifically, it relates to a heating device for boiling point and pressure experiments of high school physics. Background technique [0002] In the learning process of today's students, physical experiments are an indispensable teaching content. Through real physical experiments to help students understand and memorize the knowledge they have learned, it can help students learn more conveniently and can be used in all aspects Help teachers and students. In the development of the big environment, physical experiments require students to operate on the corresponding equipment console. However, the height of the existing physical experiment table is fixed and cannot be adjusted according to the height of the students, which affects the students' experimental operation and increases the difficulty of the experiment; in addition, in the physical experiment, it is often n...
