Abstract
The utility model relates to ceiling fan blades, which are formed by that a plurality of blades are symmetrically fixedly connected with the machine body of a ceiling fan; one face or two faces of each blade are provided with a plurality of round concave faces According to the aerodynamics principle, when the air impacts the surface with a plurality of round concave faces, various turbulent reflecting angles can be generated, and thus a turbulent current can be formed. Therefore, the ceiling fan blades not only can increase the wind force of the ceiling fan, but also can reduce the noise.
Description
Technical field
The utility model relates to ceiling fan blade, refers to a kind of wind-force that not only can increase ceiling fan especially, and can reduce the ceiling fan blade of noise.
Background technique
The two sides of known ceiling fan blade is burnishing surface, because such blade is all combined with tilt about 15 ° of angles and ceiling fan body, when the rotation of each blade and during agitation air, its impact force and reflectivity all are reciprocity angle, the air quantity that is produced can be because of the equity of angle, and evenly disperse and weaken, and can produce bigger z z z noise because of impact force, the shortcoming that this haves much room for improvement for known ceiling fan blade.
Summary of the invention
The purpose of this utility model is to provide a kind of wind-force that not only can increase ceiling fan, and can reduce the ceiling fan blade of noise.
A kind of ceiling fan blade, the body that is consolidated in ceiling fan by number blade symmetry forms; It is characterized in that: the one or both sides of each blade are provided with most circular concaves that can make air produce turbulent flow on its surface.
Advantage of the present utility model is: described in the fluid dynamic principle: the example of " distance that turbulent flow can make the golf ball of surface irregularity fly out is more than two sesquialters of smooth ball ", so be provided with most circular concaves on the surface of ceiling fan blade, during each blade rotation, air can produce turbulent flow at the blade surface of most circular concaves, therefore, can increase the wind-force of ceiling fan, and reduce its noise.
Description of drawings
Fig. 1, be plan view of the present utility model.
Fig. 2, be the broken section enlarged view of the utility model circular concave.
Fig. 3, be schematic perspective view of the present utility model.
Embodiment
For to structure of the present utility model, technical characteristics and effect thereof, can have and further understand and be familiar with, lift a preferred embodiment now, and conjunction with figs. is described in detail as follows:
Shown in Fig. 1-3, a kind of ceiling fan blade, being consolidated in the ceiling fan body by number blade 1 symmetry forms, the one side of each blade 1 is provided with most circular concaves 2, and when each blade during by the body driven rotary, air can produce turbulent flow on this blade 1 surface with most circular concaves 2, that is air is when clashing into mutually with most circular concaves 2, can present the reflection angle of multiple disorder and form turbulent flow, this kind turbulent flow not only can increase the wind-force of ceiling fan, and can reduce its noise.
Above-mentioned most circular concave 2 also can be arranged at the two sides (not shown) of each blade 1, and its action of turbulent flow is more obvious.
The above only is preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; such as those who are familiar with this art; use principle of the present utility model and technical characteristics; various changes and the decoration done all should be covered by within the category that these claims protect.
