[0037] The installation substrate 10 can be made of metal or plastic material. The air bellow 20 comprises a bellow body 21, an air inlet pipe 22 and an air outlet pipe 23. The bellow body 21, the air inlet pipe 22 and the air outlet pipe 23 are made of transparent plastic or acrylic plate. The bellow body 21 is a hollow spherical shell structure. The bellow body 21 is provided with a wind cavity 21a, a first connecting hole 21d and a second connecting hole 21c which are in communication with the wind cavity 21a. The air inlet pipe 22 is inserted into the first connecting hole 21d and is provided with an air inlet channel 22a which is in communication with the wind cavity 21a. The air outlet pipe 23 is inserted into the second connecting hole 21c and is provided with an air outlet channel 23a which is in communication with the wind cavity 21a. The air inlet channel 22a and the air outlet channel 23a form an angle of 90°. Of course, the angle can also be 30°, 60°, 120° or the like to facilitate more intuitive observation of the flow direction of the air flow. The air inlet pipe 22 and the air outlet pipe 23 are respectively inserted into the first connecting hole 21d and the second connecting hole 21c. Thus, the disassembly and assembly of the air bellow 20 is relatively simple, which facilitates storage and use.

[0038] In the present application, the air bellow 20 further comprises a first magnetic member 24. The installation substrate 10 is provided with a second magnetic member 25.
