A heating device for physical and chemical experiments

Abstract

The invention discloses a heating device for physical and chemical experiments. The heating device comprises an experiment box, an external temperature control device, a heating table, a heating device, a sliding device and a temperature control early warning detection device, wherein the external temperature control device is arranged at the inner side corner of the experiment box; the heating table is arranged at the inner side of the external temperature control device; the heating device is arranged on the heating table; the bottom is connected with the experiment box through a sliding device. The temperature control early warning detection device is arranged inside the experiment box, and consists of a temperature sensor, a controller, a warning indication lamp and an electronic temperature indicator; the temperature sensor is positioned at the bottom of the experiment box and is electrically connected with the warning indicating lamp and the electronic temperature indicator through the controller; the experiment box is arranged at the outer side of the heating equipment for performing isolation on a heating appliance at the inside; the safety of the heating equipment can be improved; the influence caused by outside on the heating process can be reduced.

Description

technical field [0001] The invention relates to the technical field of teaching experiment devices, in particular to a heating device for physical and chemical experiments. Background technique [0002] The traditional experimental heating equipment mainly uses alcohol lamps, and alcohol lamps are widely used in chemical experiments. The existing alcohol lamps lack protective devices, and the alcohol lamps are easily blown out by the wind, resulting in interruption of experiments and prolonged experiment time. . Moreover, the general windproof device is bulky and takes up a lot of manpower when used. If the protective device is fixed on the alcohol lamp, the heating device for physiological and chemical experiments is a device specially designed for heating utensils in physiological and chemical teaching. The general structure of the heating device is relatively simple, it is not safe to use in the classroom and will produce a certain odor, and there is no device for temper...

[0002] The traditional experimental heating equipment mainly uses alcohol lamps, and alcohol lamps are widely used in chemical experiments. The existing alcohol lamps lack protective devices, and the alcohol lamps are easily blown out by the wind, resulting in interruption of the experiment and prolonged experiment time.

Moreover, the general windproof device is bulky and takes up a lot of hands when used. If the protective device is fixed on the alcohol lamp, the heating device for physiological and chemical experiments is a device specially designed for heating utensils in physiological and chemical teaching. The general structure of the heating device is relatively simple, it is not safe to use in the classroom and will produce a certain odor, and there is no device for temperature control and detection, which is not conducive to improving the accuracy of the experiment

[0003] In the actual process of heating, the effect of heating will often fail to achieve the expected effect, thus making the data obtained in the experiment inaccurate and misleading teachers and students. To solve these problems, the present invention designs a heating device for physical and chemical experiments. device, targeted treatment for the heating problem in the teaching experiment process
