(x) ' 0 >, and F (x) "=0 or F (x) " are negative value (first recessed rear convex) from positive value variation, can also be the first sub- convex surface certainly
Can be face directly with cambered surface combination (partial region F (x) "=0, partial region F (x) " ≠ 0).
Further, the one end on the first sub- convex surface 21 extends to the first end 10A in air duct 10, certainly, the first sub- convex surface
It can be spaced apart with the first end 10A in air duct 10, such as the one end on the first sub- convex surface is set to the first end 10A in air duct 10
Middle part between second end 10B；Or first the one end on sub- convex surface extend to first end 10A or second end with air duct 10
10B is spaced apart 1/6L, and wherein L is the length in air duct 10.
Certainly, above-mentioned is only some specific embodiments of the present invention, is not construed as limiting the scope of the present invention.
In addition, the other end on the first sub- convex surface extends to the second end 10B in air duct 10.
Certainly, the other end on the first sub- convex surface can also not extend to the second end 10B in air duct 10, in other words, the first son
The other end on convex surface is spaced apart with the second end 10B in air duct 10.At this time, it may be necessary to which the second sub- convex surface 22 is arranged to realize the flat of air-flow
It slips over and crosses.For specific body, the first sub- convex surface is spaced apart with the second end 10B in air duct 10, and transition 103 further includes the second son
The one end on convex surface 22, the second sub- convex surface 22 is connected with the first sub- convex surface, and the first sub- convex surface and the second sub- convex surface 22 are smoothed
It crosses, and the second end 10B in the other end on the second sub- convex surface 22 towards air duct 10 extends, the second sub- convex surface 22 court in the direction of the air flow
It is tilted away from the direction of air outlet 101.
Preferably, the length of the second sub- convex surface 22 in the direction of the air flow is greater than the length of the first sub- convex surface in the direction of the air flow
Degree.In other words, the second sub- convex surface 22 is gentler relative to the first sub- convex surface.
Convex configuration 2 is located on the surface of 101 side of separate air outlet in air duct 10 so that air duct 10 includes at least one
A transition 103, the area of passage of each transition 103 from first end 10A to gradually changing on the direction of second end 10B,
At least one section of area of passage of each transition 103 is gradually reduced along from first end 10A to the direction of second end 10B, often
A transition 103 and first end 10A spacing (that is, transition 103 near first end 10A endpoint and first end
The distance between 10A) with the length ratio in air duct 10 (X1/L, X2/L as shown in Figure 4, in X3/L shown in fig. 8, Fig. 9
Shown in X4/L, X5/L, X6/L shown in Figure 10) be more than or equal to 1/6, to illustrate transition 103 not close to first end 10A
It is arranged and does not connect with first end 10A.
As a result, since convex configuration 2 is located at the space occupied inside air duct 10 in air duct 10, thus 2 meeting of convex configuration
The area of passage for causing corresponding position in air duct 10 changes.Specifically, along from first end 10A to second end 10B
Direction, if the space that convex configuration 2 occupies air duct 10 is gradually increased, the area of passage of 10 this section of air duct will gradually subtract
It is small, so that flowing through the air velocity of this section will be gradually increased；And along from first end 10A to the direction of second end 10B, if
The space that convex configuration 2 occupies air duct 10 is gradually reduced, and the area of passage of 10 this section of air duct will be gradually increased, to flow through this
The air velocity of section will gradually decrease.Thus illustrate, the flow parameter (such as speed, pressure, direction) of 10 interior air-flow of air duct
Corresponding change can occur according to the change in shape of convex configuration 2.For example, convex configuration 2 is in inclined-plane (i.e. and in the extension in air duct 10
The not parallel plane of line) shape or curve form.
Therefore, corresponding convex configuration 2 can be designed in air duct 10 according to air flow method needs, so that air outlet 101
The air-flow sprayed on entire extending direction is uniform.More particularly, due to flowing through the flow parameter of the air-flow of convex configuration 2
Consecutive variations can occur for (such as speed, pressure, direction), rather than mutate, so as to improve 2 surrounding shape of convex configuration
The problem of at vortex, and reduce convex configuration 2 and disturb resistance caused by air-flow, and then ensure that air-flow can be in air duct 10
It smoothly advances and changes, and reduce aerodynamic noise.
As shown in figure 5, since convex configuration 2 is arranged far from air outlet 101 and first end 10A, thus when air-flow flow through it is convex
It, can be after the position far from air outlet 101 and first end 10A have sufficiently changed flow parameter again from air outlet 101 when the structure 2 of face
Outflow has not changed flow parameter sufficiently in the position close to air outlet 101 without generation air-flow and has just directly passed through air outlet
The problem of 101 outflow, and do not occur at air-flow and change flow parameter in first end 10A and influence air-flow and enter air duct 10
Problem, to improve the validity that convex configuration 2 plays a role.Moreover, convex configuration 2 is arranged far from air outlet 101, can also
Avoid the problem that convex configuration 2 causes vortex at air outlet 101 and air-flow is interfered normally to spray from air outlet 101, to mention
The high reliability of outlet air.
Thus, it is possible to (be wrapped by adjusting the shape of convex configuration 2 in air duct 10 to change distribution of the air-flow in air duct 10
Include VELOCITY DISTRIBUTION, pressure indexing, directional spreding etc.), so as to adjust speed and angle that air-flow is sprayed from air outlet 101, make
Obtain the air-flow gas that is uniform, such as spraying about 100 head shown in Fig. 1 that head 100 is sent out in entirely blowing plane
Flow velocity degree and even angle the problem of upper downstream flow-disturbing will not occur and converge in front of head 100, and then can be mentioned effectively
The air supplying distance and air output of high head 100 improve user experience.
Head 100 according to an embodiment of the present invention for bladeless fan 1000 is tied by the way that convex surface is arranged in air duct 10
Structure 2 so as to improve the distribution of 10 internal gas flow of air duct, while reducing convex configuration 2 to the disturbing influence of air-flow, and reduction is made an uproar
Sound so that the outlet air of head 100 can be more uniform in entire outlet air plane, and then effectively improves going out for head 100
Wind effect, greatly improves user experience.
In the present invention, convex configuration may include spaced apart multiple in the direction of the air flow.
Preferably, different according to the position of convex configuration, convex configuration 2 can choose different length, to realize more
Add uniform outlet air.It is of course also possible to set just the same for the length of multiple convex configurations 2, in tool, there are three above
When convex configuration 2, the length of multiple convex configurations 2 can be different from or part is not identical.Wherein, the length of convex configuration 2
Degree refers to convex configuration 2 along the size of airflow direction.
In other words, in the direction of the air flow, the length dimension of multiple convex configurations 2 is identical or different.
In addition, in tool there are three when above convex configuration 2 (being arranged along airflow direction), per two adjacent convex configurations
Spacing between 2 can be identical or not identical.For example, three convex configurations distinguish table in tool there are three when convex configuration
It is shown as A, B, C.Wherein, the spacing between A, B is A-B, and the spacing between B, C is B-C, and spacing A-B can be identical with spacing B-C
Or it is different.Certainly, convex configuration may be more than four multiple.
It should be noted that the spacing between two convex configurations 2 refers to the gap between two convex configurations 2, or
It says, in the direction of the air flow, the spacing of adjacent end in the direction of the air flow in two adjacent convex configurations 2.For example, air-flow side
To for along the vertical direction when, the spacing between two convex configurations 2 refers to: one 's be located below in two convex configurations 2
Spacing between upper end and one lower end located above.
In some embodiments of the invention, convex configuration 2 can be an arc surface or can be put down by multiple arc surfaces
It slips over and crosses connection (such as connecting by rounded corner transition) and form, convex configuration 2 connect (example with the smooth surface transition in air duct 10
It is such as connected by rounded corner transition).Thus, it is possible to ensure that area of passage of the air duct 10 at convex configuration 2 continuously changes, and convex
