In order to do a good job in the construction of the key special project of "coal to electricity", accelerate the progress of the project, and help to fight poverty, it has achieved fruitful results. Due to the policy requirements of coal to electricity, there are many electric heating equipment in China, which brings great convenience to residents in winter. The heat storage and insulation device of electric heating equipment is a device that uses heat storage materials to extend the release time of heat energy and improve energy efficiency. Specifically, this device uses electric energy to heat the heat storage material to a high temperature during off-peak hours, and then releases heat energy during peak hours or when needed to keep the temperature of the equipment stable and reduce electricity consumption. The working principle of the heat storage and insulation device is to use the difference between peak and off-peak electricity prices, heat the heat storage material to a high temperature through electric heating during off-peak electricity price periods, and then release heat energy during peak electricity price periods or when needed to achieve insulation of the equipment.

[0003] For example, a heat storage and heat preservation device for electric heating equipment in announcement number CN217927814U includes a blocking and heat preservation mechanism, which includes a rectangular box, a baffle, a connecting rod, a ball and a heat preservation layer; the front side of the rectangular box is set to be an opening, and the rear side of the rectangular box is connected and fixed with an air outlet pipe.
