The whole adopts the bionic shape of the classic red mushroom of fairy tales, and the round umbrella cover is matched with the smooth closed stem. The shape is derived from the natural image in the children's picture book, which is soft and childish, and dispels the cold and serious tool perception of the traditional thermometer. The overall outline is fully rounded, free of sharp edges and corners, and avoids the risk of collision. The metal temperature measuring probe at the bottom is passivated to ensure comfortable and safe temperature measurement. The annular luminous structure of the umbrella cover simulates mushroom halo and can be used as an atmosphere lamp to add a sense of dream and healing.
