[0062] Combined with the above structure, the approximate working process of the electrical equipment is as follows:

[0063] In this embodiment, a trigger switch 7 can be set on the outer shell assembly 2 corresponding to the functional position one and the functional position two. When the fan assembly 3 realizes the fan function, after being lifted to the functional position one, the lifting base frame 33 of the fan assembly 3 touches the trigger switch 7 on the functional position one, so that after the fan assembly 3 reaches this position, 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. At this time, the motor 312 and the fan blades 313 are in forward rotation, the first fan head air outlet 301 is the air outlet, and the second fan head air outlet 302 is the air inlet, so that the fan head 31 blows air forward.

[0064] When the fan assembly 3 realizes the fan function, it is divided into two steps:

[0065] First, cut off the working circuit of the fan head 31, start the working circuit of the lifting assembly 5, and make the fan head assembly 3 descend. When the in-position trigger switch 7 on the fan assembly 3 leaves the functional position one, or before the fan assembly 3 leaves the functional position one, start the working circuit of the up and down shaking mechanism 311, so that the up and down shaking mechanism 311 drives the fan head 31 to flip upward, and the fan head 31 rotates from the horizontal state to the vertical state, and the fan head 31 coincides with the axis of the circulating air duct 203.

[0066] Second, the lifting chassis 33 of the fan assembly 3 touches the in-position trigger switch 7 on the second functional position, so that after the fan assembly reaches this position, the fan head 31 retracts into the fan chamber 231, and the first fan head air outlet 301 of the fan head 31 just stops at the first shell air outlet 201 position, and cuts off the working circuit of the lifting assembly 5, stops further descending, connects the working circuit of the heating core structure 4a, and converts the working circuit of the fan head 31. At this time, when the motor 312 and the fan blades 313 are in reverse rotation, the first fan head air outlet 301 is the air inlet, and the second fan head air outlet 302 is the air outlet, so that the fan head 31 draws the outside air from the first shell air outlet 201 into the circulating air duct 203 for transportation, and then passes through the heating core structure 4a to heat it into hot air, and then discharges it from the second shell air outlet 202 on both sides, thereby realizing the heater function. Embodiment 2:

[0067] The structure and principle of the second embodiment are basically the same as those of the first embodiment, except that Figure 8 As shown, the functional assembly 4 is an air filter structure 4b. When the fan assembly 3 is retracted into the first housing air outlet 201, the main body 1 is used as an air filter. Embodiment three:

[0068] The structure and principle of the third embodiment are basically the same as those of the first embodiment, except that Fig. 9 As shown, the functional assembly 4 is a condenser structure 4c. When the fan assembly 3 is retracted into the first shell air outlet 201, 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:

[0069] 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. For example, when the fan assembly 3 is retracted into the first outer shell air outlet 201, the main body 1 can be used as a heater or an air filter, and can perform an air filtering function while performing a heating function. The heating core structure 4a and the air filter structure 4b are arranged front and back along the circulating air duct 203. This embodiment is not marked in the drawings.
