When the air outlet structure is used, the maximum value S in the area enclosed by the cross sections of the positions of the first air outlet body 100 is larger than the maximum value S in the area enclosed by the cross sections of the positions of the first air outlet body 1001maxAnd minimum value S1minSatisfies S1max≤1.5S1minTherefore, the areas of the cross sections of the positions of the first air outlet body 100 are approximately equal or have smaller difference values, when the air current flows through the air duct of the first air outlet body 100, the air field formed in the air duct of the first air outlet body 100 is not easy to form vortex and other complex flows, and further, the wind resistance of the air duct of the first air outlet body 100 is reduced, so that the wind flowing out along the air duct of the first air outlet body 100 is improvedMeanwhile, the noise in the air duct of the first air outlet body 100 is reduced; similarly, the maximum value S of the area surrounded by the cross sections of the second air outlet body 200 at the respective positions2maxAnd minimum value S2minSatisfies S2max≤1.5S2minTherefore, the areas of the cross sections of the positions of the second air outlet body 200 are approximately equal or have smaller difference values, when the air current flows through the air duct of the second air outlet body 200, the air field formed in the air duct of the second air outlet body 200 is not easy to form complex flows such as vortex flows, and further, the wind resistance of the air duct of the second air outlet body 200 is reduced, so that the air volume flowing out along the air duct of the second air outlet body 200 is increased, and the noise in the air duct of the second air outlet body 200 is reduced; furthermore, the included angle between the first inner side surface and the end surface of the second air outlet end is A1The included angle between the second inner side surface and the end surface of the second air outlet end is A2Satisfies A1≤A2≤1.5A1In this range, it is ensured that the cross-sectional area of the air duct of the second air outlet body 200 is approximately equal to the cross-sectional area of the air duct of the first air outlet body 100, or the difference is small, and further, when the air flow flows through the air duct of the first air outlet body 100 along the air duct of the second air outlet body 200, the air flow can be prevented from generating vortex and other complex flows inside the air outlet structure, and further, the wind resistance of the air outlet structure is reduced, the air output of the air outlet structure is increased, and the noise of the whole air outlet structure is reduced. When A is2Is less than A1When the air duct inner cavity of the second air outlet body 200 is too large, the wind field formed in the air duct of the second air outlet body 200 is easy to form vortex and other complex flows, so that the wind resistance of the second air outlet body 200 is increased; when A is2Greater than 1.5A1In the process, the inner cavity of the air duct of the second air outlet body 200 is too small, and a wind field formed in the air duct of the second air outlet body 200 is easy to form complicated flows such as throttling and the like, so that the wind resistance of the second air outlet body 200 is increased; preferably, in this embodiment, a1＝28°，A2When 42, the windage of whole air-out structure is minimum, and the air output of air-out structure is the biggest, and the noise of whole air-out structure is minimum.
On the basis of the above embodiments, the area enclosed by the cross section of each position of the air duct of the first air outlet body 100 is equal to the area enclosed by the cross section of each position of the air duct of the second air outlet body 200. So, when the wind current flows through first air-out body 100 along the wind channel of second air-out body 200, because the area that the cross section in the wind channel of first air-out body 100 encloses equals with the area that the cross section in the wind channel of second air-out body 200 encloses, consequently, the wind current can be avoided producing complicated flows such as vortex in the inside of air-out structure, and then, reduces the windage of air-out structure, promotes the air output of air-out structure, has reduced the noise of air-out structure.

As shown in fig. 1, 2 and 3, the sealing plate 240 has a thickness L according to any of the above embodiments1Wherein: l is more than or equal to 01Less than or equal to 30 mm. Therefore, in this range, the flow field disorder phenomenon is not likely to occur in the air duct of the second air outlet body 200, and meanwhile, in this range, the sealing plate 240 can reliably seal the air duct of the second air outlet body 200; further, when L is more than or equal to 01When the air outlet structure is less than or equal to 30mm, the included angle A between the second cover plate 210 and the third bottom plate 230 is formed in the air outlet structure with the same length1At this time, the air flow enters the second air outlet body 200 along the air inlet 232, and the energy loss is small when the air flow collides with the second cover plate 210, so that the air output of the second air outlet body 200 is increased; in this embodiment, L1Preferably 20mm, at this time, the wind resistance of the wind channel of the second wind outlet body 200 is the smallest, and the noise in the wind channel of the second wind outlet body 200 is the lowest. It is to be noted that L1The smaller the length of the second air outlet body is, the smaller the wind resistance in the second air outlet body is.
In other embodiments, as shown in fig. 1 and 2, the sum of the length of the third base plate 230 and the thickness of the sealing plate 240 is L2Wherein:
therefore, in this range, the flow field disorder is not likely to occur in the air duct of the second air outlet body 200, and meanwhile, in this range, the sealing plate 240 can reliably seal the air duct of the second air outlet body 200; further, when
In the air outlet structure with the same length, the included angle a between the second cover plate 210 and the third bottom plate 2301Relatively large, in which case the wind current followsThe air outlet 232 enters the second air outlet body 200, and the energy loss is small when the air outlet 232 collides with the second cover plate 210, so that the air outlet quantity of the second air outlet body 200 is increased, and the noise in the air duct of the second air outlet body 200 is reduced; in this embodiment, L1Preferably 20mm, at this time, the wind resistance of the wind channel of the second wind outlet body 200 is the smallest, and the noise in the wind channel of the second wind outlet body 200 is the lowest. In practical application, L2Is designed according to the size of the air outlet of the fan 300. It is to be noted that L1The smaller the length of the second air outlet body is, the smaller the wind resistance in the second air outlet body is.
As shown in fig. 1, 2 and 3, on the basis of any of the above embodiments, the height of the sealing plate 240 is H, wherein:
thus, in this range, in the air outlet structure with the same length, the included angle between the second cover plate 210 and the third bottom plate 230 is a1At this time, the air flow enters the second air outlet body 200 along the air inlet 232, and the energy lost when the air flow collides with the second cover plate 210 is small, so that the air outlet amount of the second air outlet body 200 is increased, and the noise in the air duct of the second air outlet body 200 is reduced; when H is less than 2L1When the air inlet space of the air inlet 232 is too small, the wind field formed in the air channel of the second air outlet body 200 is easy to form complicated flow such as throttling, and thus, the wind resistance of the second air outlet body 200 is increased; when H is greater than
In the air outlet structure with the same length, the included angle between the second cover plate 210 and the third bottom plate 230 is a1The angle between the wind flow and the second cover plate 210 is close to 90 degrees, the wind flow enters the second wind outlet body 200 along the wind inlet 232, and the energy lost when the wind flow collides with the second cover plate 210 is large, so that the wind output of the second wind outlet body 200 is reduced, and the noise in the wind channel of the second wind outlet body 200 is increased; in this embodiment, L1Preferably 20mm, L2Preferably 150mm, and H preferably 60mm, at this time, the air duct wind resistance of the second air outlet body 200 is the smallest, the air outlet volume of the second air outlet body 200 is the largest, and the air duct of the second air outlet body 200 is the largestThe noise in the inner is lowest.
As shown in fig. 1, 2 and 3, in any of the above embodiments, the first outlet body 100 is a straight duct, and the length of the first bottom plate 130 is L3The projection length of the second bottom plate 220 towards the third bottom plate 230 is L4Wherein:
thus, when the first air outlet body 100 is a straight pipeline, the air flow hardly forms a vortex flow and other complex flows in the first air outlet body 100; further, when
During the process, the straight pipeline is ensured to have enough length, and the backflow of the air flow at the air outlet 110 is avoided, so that the wind resistance of the first air outlet body 100 is reduced, the air output of the first air outlet body 100 is increased, and the noise in the air channel of the first air outlet body 100 is reduced.

On the basis of any of the above embodiments, the air outlet structure further includes a sealing layer, and the sealing layer is coated or wrapped on the air duct outer wall of the first air outlet body 100 and the air duct outer wall of the second air outlet body 200. Therefore, the sealing layer can seal the first air outlet body 100 and the second air outlet body 200, and the loss of air volume is avoided; meanwhile, the sealing layer also has the function of preserving the heat of the air flow in the first air outlet body 100 and the second air outlet body 200; specifically, the sealing layer can be sponge or sealant; in this embodiment, the sealing layer is a sponge, so that the sealing layer is convenient to detach and mount.
