Through the connection of the connecting piece, the air supply mixed flow assembly 200 can be firmly fixed to the bottom of the hanging machine body 100, so that the air supply mixed flow assembly 200 and the hanging machine body 100 work cooperatively, and then a changeable air mixing and air supply scheme is realized, namely, the angle of the air supply mixed flow assembly 200 is changed at will, and various air mixing modes such as upper and lower layered mixed flow, induced air jet flow, scattered air mixed flow and the like are formed, so that various air supply mixed air experiences are provided for users.
