In this way, after image acquisition module 2 acquires the image of the environment around device main body 1, the acquired image is sent to control terminal 6, control terminal 6 determines the pixel average color value of the image by averaging the sum of R, G, B values of the pixels in the image, thereby determining the environmental color; control terminal 6 determines the corresponding temperature value corresponding to the pixel average color value of the image according to the pixel average color value of the image and the preset relationship between the corresponding temperature value and the pixel average color value in control terminal 6; temperature sensing module 5 acquires the actual temperature value in device main body 1 and sends it to control terminal 6, control terminal 6 compares the actual temperature value with the corresponding temperature value and then adjusts the temperature in device main body 1 through temperature control module 4, so that the actual temperature in device main body 1 is the same as the corresponding temperature value, at this time the color development of the ink corresponds to the environmental color. Device main body 1 has high consistency with the environment.

[0020] In the embodiment, the temperature control module 4 has a heater installed in the device body 1, and a graphene heat-conducting sheet 7 is laid on the inner wall of the device body 1. In this way, the heater can heat the device body 1 when in operation to adjust the temperature of the device body 1, and the heat can be evenly transmitted to each surface of the device body 1 under the action of the graphene heat-conducting sheet 7, so that the temperature change ink layer 3 on the surface of the device body 1 develops color uniformly.
