In order to simplify disclosure of the present utility model, hereinafter the part and setting of specific examples are described.Certainly, they are only Example, and purpose does not lie in limitation the utility model.In addition, the utility model can in different examples repeat reference numerals And/or reference letter, this repetition are for purposes of simplicity and clarity, itself not indicate discussed various embodiments And/or the relation between setting.In addition, various specific techniques and the example of material that the utility model provides, but this Field those of ordinary skill can be appreciated that the application of other techniques and/or the use of other materials.

Referring to Fig. 1, the bladeless fan 200 of the utility model embodiment includes pedestal 102 and fan first 100.Pedestal 102 For sucking air to establish air-flow and drain into fan first 100, and spray the air outlet 10 of air-flow from fan first 100.Air outlet 10 air-flows sprayed can roll up the air around inhaling to form wind, so as to meet the needs of user enjoys the cool.

Specifically, pedestal 102 includes shell 104, and shell 104 is formed with multiple air inlets 106, multiple shapes of air inlet 106 Into the multiple array air inlets being circumferentially arranged having around shell 104, multiple array air inlets are spaced apart.

It is appreciated that when bladeless fan 200 works, pedestal 102 sucks air from air inlet 106, and air passes through shell Dynamical system (not shown) in 104 forms high velocity air after accelerating, side by side to fan first 100.

Also referring to Fig. 2-Fig. 4, the fan first 100 of the utility model embodiment is formed with air outlet 10 and air-out chamber 12.Air outlet 10 connects air-out chamber 12.Air-out chamber 12 includes wind collecting section 14 and outlet section 16.Wind collecting section 14 away from air outlet 10, Outlet section 16 is close to outlet section 16.Outlet section 16 connects wind collecting section 14 and air outlet 10, on the air-out direction of outlet section 16, goes out The width W in wind portion 16 first reduces to be increased afterwards.

In the fan first 100 of present embodiment, a diffusion knot is formed because the width W of outlet section 16 first reduces to increase afterwards Structure, the flow loss at air outlet 10 can be reduced so that the air-out volume of air outlet 10 is larger, improves Consumer's Experience.Separately Outside, the noise of air outlet 10 can also so be reduced.

Specifically, first 100 are fanned annularly, fan first 100 includes the first bending section 18, the second bending section 20 and line part 22. First bending section 18 is set close to the pedestal 102 of bladeless fan 200.Second bending section 20 is set away from pedestal 102.Line part 22 The first bending section 18 and the second bending section 20 are connected, air-out chamber 12 is formed in the first bending section 18 and line part 22.

Air-flow from the row of pedestal 102 to fan first 100 when, air-flow from air outlet 10 spray when, due to the inertial flow of air-flow, gas Stream sprays along the direction that tilts upward, air-out chamber 12 be formed in the first bending section 18 and line part 22 can so that air-flow from going out Air port 10 spray when, the angle that air-flow tilts upward ejection can be reduced so that air-flow spray in the horizontal direction as much as possible with The wind for blowing to user is formed, so as to improve the experience of user.

Specifically, the first bending section 18 and the second bending section 20 can be in arc-shaped, and thus, fan first 100 is in runway ring-type, So that fan first 100 is more attractive in appearance.

In some embodiments, the volume of wind collecting section 14 is more than the volume of outlet section 16.In this way, wind collecting section 14 can receive Hold more air-flows, when air-flow flows to outlet section 16 from wind collecting section 14, because the volume of air-flow diminishes, so as to improve air-flow Flowing velocity, and then cause air outlet 10 air-flow speed increase with improve fan first 100 blowing range capability.

In some embodiments, fan first 100 includes first inner wall section 24 for limiting air-out chamber 12 and two second Inner wall section 26.First inner wall section 24 is relative with air outlet 10, and the both ends of the first inner wall section 24 connect two the second inner wall sections respectively 26 one end, the other end of two the second inner wall sections 26 limit air outlet 10.

In other words, air-out chamber 12 is enclosed and formed by the first inner wall section 24 and two the second inner wall sections 26, and encloses to be formed out Air port 10.It is preferred that the first inner wall section 24 in arc-shaped to reduce air current flow when resistance, so as to reduce air current flow Caused noise.

In some embodiments, two the second inner wall sections 26 include the straightway 28 of the first inner wall section 24 of connection respectively, In other words, each second inner wall section 26 includes a straightway 28, and any one straightway 28 connects the first inner wall section 24.Two The inner wall section 24 of straightway 28 and first limits wind collecting section 14 jointly.

In this way, wind collecting section 14 can form larger volume.In addition, when the first inner wall section 24 is arc-shaped, two straight 28 and first inner wall section of line segment, 24 tangent connection can gently flow to straightway 28 so as to obtain air-flow from the first inner wall section 24 Enter outlet section 16 afterwards.

In some embodiments, two the second inner wall sections 26 respectively include connection straightway 28 wind outlet section 30, two Wind outlet section 30 limits outlet section 16 jointly.

Two wind outlet sections 30 include the first linkage section 32 and the second linkage section 34, the first linkage section 32 connection straightway respectively 28 and second linkage section 34, two one end of the second linkage section 34 away from the first linkage section 32 limit air outlet 10 jointly.

On the air-out direction of outlet section 16, two the first linkage sections 32 gather so that outlet section 16 width reduce, two Individual second linkage section 34 is first gathered to be expanded so that the width of outlet section 16 first reduces increases afterwards afterwards.

In this way, the width of outlet section 16 increases after reducing so that outlet section 16 forms diffusion structure to reduce the damage of air quantity Lose.

In some embodiments, the length L1 of the first linkage section 32 is more than the length L2, i.e. L1 ＞ of the second linkage section 34 L2。

In this way, air-flow is shorter by the time of the second linkage section 34, rapidly can be sprayed from air outlet 10, to reduce gas The loss of stream.

It is pointed out that L1 and L2 are referred respectively on the air-out direction of outlet section 16, the chi of the first linkage section 32 Very little and the second linkage section 34 size.

In some embodiments, the first linkage section 32 and the second linkage section 34 type in curved surface, the first linkage section 32 with The rounding off of second linkage section 34 connects.

In this way, the first linkage section 32 and the second linkage section 34 of curved face type can reduce the loss of air current flow, so as to To ensure the wind velocity that goes out of air outlet 10, and the generation for fanning first 100 noise can be reduced.

In the description of this specification, reference term " embodiment ", " some embodiments ", " schematically implementation The description of mode ", " example ", " specific example " or " some examples " etc. means with reference to the embodiment or example description Specific features, structure, material or feature are contained at least one embodiment or example of the present utility model.In this explanation In book, identical embodiment or example are not necessarily referring to the schematic representation of above-mentioned term.Moreover, the specific spy of description Sign, structure, material or feature can combine in an appropriate manner in any one or more embodiments or example.

While there has been shown and described that embodiment of the present utility model, one of ordinary skill in the art can manage Solution：A variety of to the progress of these embodiments can change in the case where not departing from principle and objective of the present utility model, change, Replace and modification, the scope of the utility model are limited by claim and its equivalent.
