The reflecting layer 3 is arranged on the upper surface of the heat preservation layer 2, the heating layer 5 is arranged on the upper surface of the reflecting layer 3, and the soaking layer 6 is arranged on the upper surface of the heating layer 5. The soaking layer 6 is used for conducting heat generated by the heat generating layer 5 and reflected by the heat insulating layer 2 and the reflecting layer 3, and when a first area of the soaking layer 6 is covered by a covering, the energy of the first area can be conducted to the surrounding area of the first area by the soaking layer 6 so as to homogenize the surface temperature of the soaking layer 6; the paving area of the uniform heating layer 6 is larger than that of the heating layer 5, and the edge of the uniform heating layer 6 exceeds the edge of the heating layer 5.

Specifically, when the heating layer 5 works, due to the thermal temperature difference, heat generated by the heating layer 5 can be transferred in two directions, namely upward and downward, wherein in the process of transferring the heat transferred downward, a part of the heat meets the reflecting layer 3 and is reflected, and then is transferred upward; and the other part of the heat transferred downwards can be transferred downwards continuously, and the other part of the heat transferred downwards can not be effectively transferred continuously after meeting the heat preservation layer 2, so that the temperature of the heat preservation layer 2 is gradually increased. After the temperature of the heat preservation layer 2 rises to a certain temperature, the heat transferred downwards generated by the heating layer 5 and the heat reflected upwards by the heat preservation layer 2 reach balance, no redundant heat is transferred downwards continuously at the moment, and therefore the heat preservation layer 2 plays a role in heat preservation and reduces heat loss.
