Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to fig. 1 to 4. The utility model provides a split type heating base, includes casing 1, circuit board 2 and the dish 3 that generates heat, in casing 1 was all located to circuit board 2 and the dish 3 that generates heat, the dish 3 that generates heat was connected through the wire electricity with circuit board 2, and the surface of the dish 3 that generates heat is equipped with temperature change coating 4. The shell 1 is a plastic shell, and the circuit board 2 is connected with an external power supply through a wire; the circuit board 2 is the same as that used in a conventional electric kettle.

In the actual use process, the temperature change coating 4 is formed by mixing and coating the following components in parts by weight:

silicon dioxide: 15 percent of aluminum oxide, 35 percent of titanium dioxide, 10 percent of water, 5 percent of isopropyl alcohol, 5 percent of thermochromic powder and 5 percent of heat-conducting silicone grease.

The temperature-sensitive color-changing powder can adopt a thermal color elimination type (R series) of Shenzhen color-changing science and technology Limited, the temperature-sensitive color-changing powder is in a colored state at low temperature, and the pigment is gradually changed from colored to colorless when the temperature is increased to a set value. Therefore, the approximate temperature of the heating plate 3 can be known according to the color densities of the temperature sensing color-changing powder at different temperatures, and when the color-changing layer 4 is colorless, the heating plate 3 is known to exceed the preset maximum temperature. Certainly, the temperature-sensitive color-changing powder with the opposite color-changing principle can be selected, namely, the color of the temperature-sensitive color-changing powder is colorless at low temperature and gradually changes into color at preset high temperature.

Since the temperature-variable coating 4 contains the temperature-sensitive color-variable powder, the temperature-variable coating 4 can display different colors along with the temperature change, and the temperature-variable coating 4 contains the heat-conductive silicone grease, the temperature-variable coating 4 can have good heat conductivity and thermal efficiency, and aging resistance, since the heat-conductive silicone grease has high heat conductivity, excellent heat conductivity, and high and low temperature resistance, water resistance, ozone resistance, and weather resistance.
