In a preferred embodiment, the first air outlet portion 10 and the second air outlet portion 20 are disposed in sequence in the air supply direction. Further, the second air outlet 20 has a second air outlet 21, and the second air outlet 20 is movably disposed opposite to the first air outlet 10. And the second air outlet 21 is disposed corresponding to the first air outlet 11, so that in a moving stroke of the second air outlet 20 relative to the first air outlet 10, a projection overlapping range of the first air outlet 11 and the second air outlet 21 in the first air supply direction changes accordingly.
It can be appreciated that the overlapping range of the projections of the first air outlet 11 and the second air outlet 21 in the air supply direction, that is, the air outlet range of the electric fan 100, and the area of the overlapping range, that is, the air outlet area of the air outlet assembly 50. When the projections of the first air outlet 11 and the second air outlet 21 in the air supply direction overlap more, the larger the air outlet area of the air outlet assembly 50 is, the more the projections of the first air outlet 11 and the second air outlet 21 in the air supply direction are staggered, the smaller the air supply area of the air outlet assembly 50 is. The projection positions of the first air outlet 11 and the second air outlet 21 in the air supply direction may also be changed, so as to realize the air supply of the air outlet assembly 50 at different positions. In this embodiment, the second air outlet 20 is movably disposed relative to the first air outlet 10, so as to adjust the projection overlapping range of the first air outlet 11 and the second air outlet 21 in the air supply direction, that is, adjust the air outlet area and the air outlet position of the air outlet assembly 50. The air outlet assembly 50 in this embodiment has a plurality of air outlet areas with adjustable and air outlet positions, so that the air outlet assembly 50 can be adjusted according to actual use requirements, different air outlet effects of the electric fan 100 are realized, and user experience is good.

In an embodiment, the first air outlet portion 10 is made of plastic or metal. In a preferred embodiment, the first air outlet portion 10 and the second air outlet portion 20 are both plate-shaped and substantially parallel to each other. In this way, the dimension of the air blowing assembly in the air blowing direction is defined to be thin, and at the same time, the first air outlet 11 and the second air outlet 21 can also be set to be large, so that the electric fan 100 has a compact structure and a small dimension while securing the air outlet area of the electric fan 100.
It can be appreciated that, because the second air outlet 20 is movably disposed relative to the first air outlet 10, the first air outlet 10 is spaced from the second air outlet 20, so as to avoid collision when the second air outlet 20 is movable. Preferably, the minimum distance between the first air outlet portion 10 and the second air outlet portion 20 is 3mm or more and 20mm or less. So that the electric fan 100 is compact, and the movement of the second air outlet 20 is not disturbed.

In an embodiment, the second air outlet 20 has a first working position and a second working position relative to the first air outlet 10, and an air outlet area of the air outlet assembly 50 in the first working position is larger than an air outlet area in the second working position. In this embodiment, when the second air outlet 20 is located at the first working position relative to the first air outlet 10, the projection areas of the first air outlet 11 and the second air outlet 21 in the air supply direction are larger. And when the second air outlet 20 is located at the second working position relative to the first air outlet 10, the projection areas of the first air outlet 11 and the second air outlet 21 in the air supply direction are smaller. In this way, when the electric fan 100 is required to provide a larger air supply amount, the second air outlet portion 20 may be driven to move to the first working position, whereas when the electric fan 100 is required to provide a smaller air supply amount, the second air outlet portion 20 may be driven to move to the second working position. Therefore, through the setting of the air outlet assembly 50, the switching adjustment of the large air supply range and the small air supply range of the electric fan 100 is realized, so that the electric fan 100 has different air outlet effects, can meet diversified use requirements of users, and has good use experience.
In a preferred embodiment, the second air outlet 20 further has a third working position, which is completely offset in the air supply direction, with respect to the first air outlet 10, of the first air outlet 11 and the second air outlet 21. In this embodiment, when the electric fan 100 stops working, in order to reduce the dust falling from the electric fan 100 or make the appearance of the electric fan 100 more attractive, the second air outlet 20 may be driven to move to the third working position, and at this time, the first air outlet 11 and the second air outlet 21 are completely staggered, so that the air outlet side opening of the air guiding ring 40 is closed by the air outlet assembly 50, and the dust-proof effect of the electric fan 100 is improved. Thus, after the electric fan 100 is not used for a long time, the electric fan 100 can be directly used without cleaning after being turned on again.
With continued reference to fig. 4 to 7, the second air outlet portion 20 is rotatably mounted on the first air outlet portion 10, and a rotating shaft of the second air outlet portion 20 extends along the air supply direction. In this embodiment, the second air outlet 20 rotates relative to the first air outlet 10, so that the second air outlet 20 does not occupy too much space when being adjusted between a plurality of working positions, so that the electric fan 100 is lighter and more convenient. And, the second air outlet portion 20 is rotatably mounted on the first air outlet portion 10, so that the second air outlet portion 20 and the first air outlet portion 10 are combined into an integral member, and the assembly of the second air outlet portion and the first air outlet portion is convenient to the air guide ring 40, so that the assembly and disassembly of the electric fan 100 are more convenient, and the production and maintenance efficiency is improved.
It will be appreciated that in some embodiments, the second air outlet 20 may be manually driven to rotate relative to the first air outlet 10. For example, a handle may be disposed at an edge or a middle of the second air outlet portion 20, and a plurality of gears may be disposed at an installation position between the second driving portion and the first driving portion, where the plurality of gears correspond to the first working position, the second working position, and the third working position, so that the second driving portion may be limited at the corresponding working positions. When the air outlet effect of the electric fan 100 needs to be adjusted, the handle may be operated to drive the second air outlet 20 to rotate to the corresponding first working position, second working position or third working position, so as to achieve the adjustment of the large air volume, small air volume and closing of the air outlet of the electric fan 100.
