Because the inner surfaces of the building blocks are bent in shape and have more corners, the range of the inner surfaces covered by the heat conduction layer 23 can be determined according to the actual needs and the principle of considering the manufacturing convenience, and of course, the heat conduction layer 23 can preferably fully cover the inner wall of the shell 21 under the condition of not considering the manufacturing cost, so that the temperature uniformity of the building blocks is facilitated. In some embodiments, the heat conductive layer 23 may be adhered to the inner wall of the housing 21 by gluing or the like.

In this embodiment, the pattern layer 24 may be a color coating layer formed by thermally spraying a thermochromic paint on the outer surface of the housing 21, or a color coating layer formed by spraying a thermochromic paint according to a certain pattern, because the pattern layer 24 is made of the thermochromic paint, different colors and/or different patterns can be displayed at different temperatures, if the temperature of the building block changes, the pattern layer 24 may be made to display different colors or different patterns, specifically, the colors or patterns can be displayed, the color or patterns can be selected according to the actual requirement of the building block playing method, for example, only changing the color, only the monochromatic pattern layer 24 needs to be sprayed, so that the color can be changed and displayed according to different temperatures, if there is a certain scene requirement or the visual effect of the building block is pursued, some patterns can be designed on the building block, the patterns are made by spraying temperature-sensitive color-changing coatings with different colors, and the colors in the patterns can also change when the temperature changes. In other embodiments, the patterned layer 24 may be a plurality of layers or different patterned layers 24 may be disposed on different surfaces, so as to realize diversification of patterns.

It should be noted here that the thermochromic paint contains the color-changing powder and can display different colors at different temperatures according to different proportions of the color-changing powder, which is a known relatively mature technology.

Of course, temperature control is also a prior art, and the temperature control element with a proper size can be selected according to the actual shape and size of the building block without improving the temperature control element.
