The inner shell is fitted inside the main outer shell, and the upper and lower ends of the inner shell are open. A liquid storage bottle receiving cavity extends downward from the upper opening inside the inner shell. A connecting air passage for docking with the first port is provided on the outside of the liquid storage bottle receiving cavity. The lower end of the connecting air passage is inserted into an air pipe for connecting an air pump. The air pump is installed inside the inner shell corresponding to the liquid storage bottle receiving cavity. The control board is fixed on the bottom shell. The bottom shell, the inner shell, and the main outer shell are connected and fixed by screws through connecting screw posts.

7. The aromatherapy machine of claim 6, wherein, The inner housing also contains a rechargeable battery, which is connected to the control board.
