Specific implementation mode
Invention is further described in detail below in conjunction with the accompanying drawings.
It should be noted that the present invention is not particularly limited the type of axial-flow leaf, the present embodiment is only with axis stream axis stream
The axial-flow leaf of this concrete type of fan blade illustrates.Separately it is noted that unless otherwise specified, the present invention uses all
Technical and scientific term has and the normally understood identical meanings of general technical staff of the technical field of the invention.It is not rushing
In the case of prominent, the feature in embodiment and embodiment in the present invention can be combined with each other.
In the present invention, in the absence of explanation to the contrary, the noun of locality used is typically directed to attached drawing as " upper and lower "
Shown in for direction, or on vertical, vertical or gravity direction；Similarly, it for ease of understanding and retouches
It states, " left and right " is typically for shown in the drawings left and right；" inside and outside " refers to the inside and outside of the profile relative to each component itself,
But the above-mentioned noun of locality is not intended to restrict the invention.
In order to solve the problems, such as that axial-flow leaf upper end is easy accumulation soil, rainwater in the prior art, the present invention provides one
Kind axial-flow leaf and the air conditioner with it.
As shown in Figs 1-4, axial-flow leaf of the invention includes blade 1 and wheel hub, is provided on the wheel hub surface 3 of axial-flow leaf
Through-hole 4, the center of wheel hub surface 3 are additionally provided with the axis hole 2 for installing shaft (not shown).
It should be noted that the present invention is not particularly limited the installation direction of axial-flow leaf, but when the peace of axial-flow leaf
When filling direction towards downwardly direction, beneficial effects of the present invention become apparent with embodying.The present embodiment is only with axial-flow leaf direction
Under direction installation for illustrate.
Through-hole 4 requires to run through inside and outside axial-flow leaf, and perforation direction is preferably set along the direction of airflow
It sets.
The quantity and arrangement of through-hole 4 do not have particular/special requirement, but in order to keep the air blast effect of through-hole 4 more balanced, from
Have much impact without being accepted to the rotation of axial-flow leaf, the present embodiment preferably by through-hole 4 centered on axis hole symmetrical cloth
It sets.
