[0058] Combined with the above structure, the main body roughly works as follows:

[0059] In this embodiment, a trigger switch 7 can be set on the movable shell 25 corresponding to the functional position one and the functional position two. When the fan assembly 3 realizes the fan function, after the movable shell 25 descends to the functional position one, the movable shell 25 touches the trigger switch 7 on the functional position one, so that the movable shell 25 is nested in the fixed shell 24, and the working circuit of the heating core structure 4a and the lifting assembly 5 is cut off, and then the working circuit of the up and down shaking mechanism 311 is started, so that the up and down shaking mechanism 311 drives the fan head 31 to flip downward, and the fan head 31 rotates from the vertical state to the horizontal state, and the working circuit of the fan head 31 is converted.

When the movable outer shell 25 is covered on the periphery of the fan assembly 3 and the fan assembly 3 is placed in the circulating air duct 203, the main body 1 is used as a dehumidifier. The dehumidification principle of the dehumidifier mainly adopts the working principle of the refrigeration system. The condenser structure 4c, as one of the components in the refrigeration system, actually also includes a compression pump, an evaporator and other components, and can be used in conjunction with a water receiving box structure. The above-mentioned refrigeration system belongs to the prior art and is not elaborated in detail and marked with figures in this embodiment. Embodiment 4:

[0065] The structure and principle of embodiment 4 are basically the same as those of embodiment 1, except that the functional assembly 4 includes one or more combinations of a heating core structure 4a, an air filter structure 4b, and a condenser structure 4c.
