As depicted in figs. 1 and 2, the bladeless fan of the present embodiment includes shell 10 and annular impeller 20.Wherein, in shell 10
With annular cavity 11, shell 10 has air inlet 12 and air outlet 13.Air inlet 12 and air outlet 13 with annular cavity 11
Connection.Annular impeller 20 is rotatably arranged in annular cavity 11.Driving mechanism setting is in shell 10 and drives annular leaf
20 rotation of wheel.
Using the technical solution of the present embodiment, it sets fan blade to annular impeller 20, and annular impeller 20 is directly arranged
In annular cavity 11.When driving structure driving annular impeller 20 rotates, air-flow enters to annular cavity 11 from air inlet 12
In and from air outlet 13 flow out.Above structure make bladeless fan need not in the structures such as wind turbine in setting pedestal and pedestal,
So that the volume of bladeless fan greatly reduces, and make bladeless fan put flexibility higher (such as be placed in desk,
Cabinet is first-class), usage experience is more preferable, therefore the technical solution of the present embodiment solves bladeless fan volume in the prior art
Greatly, put that degree of freedom is low, the problem of using flexible difference.
As depicted in figs. 1 and 2, in the technical solution of the present embodiment, the central axis and annular impeller of annular cavity 11
20 central axis overlaps.Specifically, annular impeller 20 is rounded, and annular cavity 11 is also rounded.Annular impeller 20 is placed on
In annular cavity 11, and the center line of annular impeller 20 and annular cavity 11 overlaps setting, and then ensures 20 energy of annular impeller
It is enough to be rotated in annular cavity 11.For annular impeller 20 during rotation, air-flow is sucked into annular cavity from air inlet 12
In 11, then air-flow is blown out from air outlet 13, to realize the effect of blowing.
As depicted in figs. 1 and 2, in the technical solution of the present embodiment, the structure in a ring of shell 10.Specifically, above-mentioned knot
Structure makes the area occupied smaller of bladeless fan, appearance more succinct.Preferably shell 10 is in cirque structure, is shape in shell 10
At above-mentioned annular cavity 11.Certainly, the shape of shell 10 is not limited to annular, for example, shell 10 or dish type, annular
Inner cavity 11 is arranged in the shell 10 of dish type.Further, shell 10 is also not necessarily limited to circular configuration, such as the shape of shell 10
Can be rectangular, polygon, irregular shape etc..
As depicted in figs. 1 and 2, in the technical solution of the present embodiment, shell 10 includes first annular side plate 14, the second ring
Shape side plate 15, first end plate 16 and the second end plate 17.Wherein, the second annular side plate 15 is located at the interior of first annular side plate 14
Side.First end plate 16 is connected between first annular side plate 14 and first end and the first end of the second annular side plate 15.Second end
Plate 17 is connected between first annular side plate 14 and second end and the second end of the second annular side plate 15.Wherein, first annular side
Annular cavity 11 is surrounded between plate 14, the second annular side plate 15, first end plate 16 and the second end plate 17.Specifically, first annular
Side plate 14 and the second annular side plate 15 are the plate-shaped member of annular, and the diameter of the second annular side plate 15 is less than first annular side plate
14 diameter, and the second annular side plate 15 is located at the inside of first annular side plate 14.Preferably, first annular side plate 14 and
It is arranged in parallel between second ring side plate 15.First end plate 16 and the second end plate 17 are also the platy structure of annular.Above-mentioned first
Annular side plate 14, the second annular side plate 15, first end plate 16 and the second end plate 17 limit closed cavity jointly, and are formed
The annular cavity 11 stated.
As depicted in figs. 1 and 2, in the technical solution of the present embodiment, air inlet 12 is formed in 14 He of first annular side plate

Mouth 12.Further, in order to ensure structural strength, it is provided with connecting pole between first annular side plate 14 and the second end plate 17, connects
The connection structures such as contact pin link together first annular side plate 14 and the second end plate 17.Air inlet 12 can be to be formed in
Gap between adjacent connection structure.It can be observed from fig. 2 that due to being arranged air inlet in first annular side plate 14 and second
Between end plate 17, therefore air inlet 12 is located at the position in the closer outside of shell 10, and the range to ensure air inlet is larger, into
Air quantity is also larger as far as possible.
Certainly, the set-up mode of air inlet 12 is without being limited thereto.For example, air inlet 12 can also be formed in the second annular side plate
15 and second between end plate 17 or air inlet 12 is formed on the second end plate 17.Further, when air inlet 12 is formed in
When on two end plates 17, can corresponding hole or slot structure be set on the second end plate 17.Meanwhile second end plate 17 and the first ring
It can be closing connection between shape side plate 14 and the second annular side plate 15, further increase the intensity of shell 10.
As depicted in figs. 1 and 2, in the technical solution of the present embodiment, air outlet 13 is arranged in 14 He of first annular side plate
Either air outlet 13 is arranged between the second annular side plate 15 and first end plate 16 or air outlet 13 between first end plate 16
It is formed in first end plate 16.The set-up mode of air outlet 13 is similar with the set-up mode of air inlet 12, and details are not described herein.
Pass through above structure so that user can't see internal annular impeller 20 in appearance, be merely able to see shell 10
On air inlet 12 and air outlet 13, and then play the effect of hiding annular impeller 20.Meanwhile the bladeless fan of the application and existing
There is the bladeless fan in technology to compare, no longer there is traditional understructure, so that small product size substantially reduces, Ke Yishi
Existing product miniaturization.Meanwhile the bladeless fan of the application placement position and usage scenario it is more flexible, compared with the existing technology
In bladeless fan be merely able to be placed into ground, the bladeless fan of the application can be placed into desk, at the positions such as desk.Or
The bladeless fan of person, the application can be also suspended on wall, or hanging is on the ceiling, and be incorporated into interior decoration.
As depicted in figs. 1 and 2, in the technical solution of the present embodiment, between first end plate 16 and the second end plate 17 away from
From along first annular side plate 14 towards being gradually reduced on the direction of the second annular side plate 15.Above structure makes the appearance of product
More attractive, decoration performance is more preferable.
