Problems solved by technology
[0002] At present, laboratories or manufacturers often use electric heating plates to heat and digest test samples, boil them, steam acid, etc. Most electric heating plates have step-by-step switches, which can only control the heating temperature of test samples within a temperature range. However, in some special cases, when a test product with a specific temperature is required to meet a certain demand, the existing electric heating plate cannot meet such a demand. In addition, the bottom of the electric heating plate will always maintain a certain temperature when it is used for a long time. , it is bound to cause damage to the items under the equipment, so it is urgent to provide an electric heating plate with a heat insulation device and real-time temperature observation

Embodiment
[0013] Such as figure 1 , the electric heating plate is composed of a box body 1, a switch 2, a digital display 3, a heating surface 4, a foot 5, and a heat insulation layer 6. The digital display 3 and the switch 2 are arranged on the box body 1, and the heating surface 4 is arranged on the box body 1. On the upper surface of the upper surface, the temperature sensor (not shown in the figure) is set in the box body 1 and is fixedly connected with the heating surface 4. After the switch 2 is turned on, the temperature display 3 can display the real-time temperature measured by the temperature sensor, which is convenient Observation shows that there is a heating element inside the box body 1. The heating element is specifically an iron-chromium-aluminum alloy wire. The iron-chromium-aluminum alloy wire is wound into a spiral shape and embedded on the refractory material. It is controlled by a switch. The surrounding and bottom of the heating element are filled with glass. Insul...
