[0002] "Mushrooms include shiitake, enoki, tea tree mushrooms, king oyster mushrooms and hericium erinaceus. Shiitake mushrooms are brown in color, white in flesh and fragrant, while enoki mushrooms are slender in shape and white or yellow in color. King oyster mushrooms are larger in size and gray in color, while tea tree mushrooms are reddish brown in color and similar in shape to shiitake mushrooms. As we all know, the cultivation of edible mushrooms has very demanding requirements on the environment. The influencing factors mainly include temperature, water, humidity, light, air, etc. The mycelium growth stage has low requirements on air, while the fruiting body growth stage must have smoother air. In addition, a large amount of heat will be generated during the mycelium cultivation process. This heat will directly enter the environment, causing waste.

[0003] Therefore, there is an urgent need for a mushroom culture box that can recycle heat, has high recycling efficiency and saves energy. Summary of the invention
