[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] See also Figure 1-6 : In this embodiment, a microcrystalline electric heating plate with a heat insulation device includes a base 1 and a support leg 2. The lower end of the base 1 is fixedly connected to the support leg 2, and the outer wall of the base 1 is fixedly connected to the operation panel 3. The surface of the operation panel 3 is installed with a control knob 4 and a power button 5, and the outer wall of the base 1 is connected to a heat insulation mechanism 6.

[0022] The heat insulation mechanism 6 includes a fixing bar 601, which is lifted upward by the heat insulation frame 605, and the heat insulation frame 605 provides heat insulation for the frame 10. The outer wall of the fixing bar 601 is fixedly connected to the base 1, and the inner wall of the fixing bar 601 is processed with a slide groove 602. The inner wall of the slide groove 602 is slidably connected to the slider 603. The outer wall of the slider 603 is fixedly connected to the fixing block 604. The outer wall of the fixing block 604 is fixedly connected to the heat insulation frame 605.

[0023] Manually push the insulation frame 605 upward, and the insulation frame 605 drives the slider 603 to move in the slide groove 602 on the fixed bar 601, so that the insulation frame 605 is lifted upward, and the insulation frame 605 has an insulation effect on the frame 10, pushing the square rod 803 to move on the mounting bracket 801, and the end of the square rod 803 is inserted into the inner wall of the fixed bar 601. The square rod 803 limits the position of the insulation frame 605 on the mounting bracket 801, so that it is easy to avoid accidental touching of the edge during use and it will be more easily installed during use.

[0024] A hole 7 is processed inside the insulation frame 605, and a fixing mechanism 8 is connected to the lower end of the insulation frame 605. The fixing mechanism 8 includes a mounting frame 801, which is inserted into the inner wall of the fixing bar 601 through the end of the square rod 803, so as to fix the position between the insulation frame 605 and the base 1. The upper end of the mounting frame 801 is fixedly connected to the insulation frame 605, and the inner wall of the mounting frame 801 is slidingly connected to the square rod 803. The outer wall of the square rod 803 is tightly pressed against the fixing rod 804, and the outer wall of the fixing rod 804 is fixedly connected to the mounting frame 801. The inner wall of the mounting frame 801 is tightly pressed against the torsion spring 802, and the end of the torsion spring 802 is tightly pressed against the fixing rod 804.

[0025] Working principle:

[0026] Use phase

[0027] By controlling the power button 5 on the operation panel 3, the heating element 12 is powered to generate heat, and the heat is absorbed to the surface of the microcrystalline glass plate 13 to generate heat. Turning the control knob 4 adjusts the power supply so that the heating element 12 emits different amounts of heat, so that the upper surface of the microcrystalline glass plate 13 can be used.

[0028] Insulation stage

[0029] In order to prevent the heat generated by the heating element 12 from being transferred to the surrounding heat and causing the risk of touching, the frame 10 is insulated with the first layer, and the insulation frame 605 is manually pushed upward. The insulation frame 605 drives the slider 603 to move in the slide groove 602 on the fixing bar 601, so that the insulation frame 605 is lifted upward, and the insulation frame 605 isolates the frame 10 at the same distance to prevent the user from touching the high-temperature frame 10. At the same time, it is necessary to press the fixing rod 804 on the mounting frame 801 to deflect it. The end of the fixing rod 804 is separated from the square rod 803, and the fixing rod 804 squeezes the torsion spring to deform, pushing the square rod 803 to move on the mounting frame 801, so that the end of the square rod 803 is inserted into the inner wall of the fixing bar 601, and the square rod 803 limits the position of the insulation frame 605 on the mounting frame 801. Stop pressing the fixing rod 804, so that the fixing bar 601 is inserted into the inside of the square rod 803, and the position of the square rod 803 is fixed.

[0032] Working principle:

[0033] The microcrystalline glass plate 13 is a high-temperature resistant material with high insulation, high power, fast heating, and a heating temperature of up to 450°C. It is safe and hygienic. The ceramic insulating layer 11 is printed with a resistance paste heating film on the microcrystalline glass plate 13 to increase the heating speed.
