Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with accompanying drawing, specific embodiment is described in detail.
As it is shown in figure 1, Fig. 1 is the structural representation of the present invention, including base the 1, first lampshade 2, heat sink 3, substrate the 4, second lampshade 5, mozzle the 6, first blade the 7, second blade 8, rotating shaft 9, rain cover 11 and pole 12.
First lampshade the 2, second lampshade 5 and substrate 4 are installed on base 1, and second lampshade 5 be positioned at the first lampshade 2, substrate 4 is positioned at the second lampshade 5, substrate 4 is tubular construction, when being embodied as, the diameter at substrate 4 two ends is more than the diameter of mid portion, lamp bead 10 tapers into along the substrate 4 directional spreding density from centre to two ends, is so conducive to producing to be close to the eddy current of substrate 4 motion when air-flow is by substrate 4, thus taking away more heat.Substrate 4 periphery is provided with multiple lamp bead 10.
First end of mozzle 6 and the second lampshade 5 connect away from one end of base；Heat sink 3 is arranged on the first lampshade 2 one end away from base 1, and be connected with the second end of mozzle 6, form the first air duct and the second air duct, first air duct is surrounded by the first lampshade 2 inwall, mozzle 6 periphery and the second lampshade 5 periphery, and the second air duct is surrounded by mozzle 6 inwall, the second lampshade 5 inwall and substrate 4.
Base 1 is provided with the first hole 101 that multiple centrage is C shape, and the first hole 101 all connects with the first air duct, the second air duct.When being embodied as, first hole 101 diameter from centre to two ends becomes larger.Heat sink 3 is provided with the second hole 301 that multiple centrage is C shape near the side of the first lampshade 2, and the second hole 301 all connects with the first air duct, the second air duct, and forms annular air-flow path；When being embodied as, heat sink 3 is provided with multiple thermal column 302, and thermal column 302 is evenly distributed on the heat sink 3 side away from the first lampshade 2.So, add area of dissipation, when wind is blown over from heat sink 3 surface, it is possible to take away more heat, thus improving radiating efficiency.
In present embodiment, base 1 being additionally provided with the 3rd hole 102, the 3rd hole 102 and the first hole 101 on base 1, space between substrate 4 and the second lampshade 5 all connect.So, it is possible to ensure that steam flow passes through from inwall and the periphery of substrate 4, from the inwall of substrate 4 and periphery, it is dispelled the heat, be conducive to improving radiating efficiency.
Rotating shaft 9 may be rotatably mounted on heat sink 3, and its first end is through heat sink 3 and is positioned at mozzle 6, and rotating shaft 9 second end is positioned at the heat sink 3 side away from the first lampshade 2；Multiple first blades 7 are arranged on the first end of rotating shaft 9, and multiple second blades 8 are arranged on the second end of rotating shaft 9.First blade 7 is equal with the quantity of the second blade and the surface area of the first blade 7 is less than the surface area of the second blade 8.When being embodied as, the second blade 8 is spherical calotte structure, and the side for plane has groove structure.So, it is ensured that the side of the second blade 8 has groove, and opposite side has smooth structure, thus ensureing when blowing air over, the power suffered by the second blade 8 is different, produces rotating torque and drives the first blade 7 to rotate.
In present embodiment, pole 12 first end is arranged on the heat sink 3 side away from the first lampshade 2 and the distribution of multiple pole 12 circular array, and rain cover 11 is connected with the second end of pole 12.When being embodied as, rain cover 11 has pyramidal structure.So, rotating shaft 9 can being prevented to be subject to rain erosion, pyramidal structure is conducive to being discharged by rainwater in time.
In present embodiment, heat sink 3 periphery is provided with thermal insulation layer 13.Owing to heat sink 3 temperature in the process of heat radiation raises, too high and people is caused scald by the circumferential temperature that prevents heat sink 3 at thermal insulation layer 13.The radiating surface making heat sink 3 concentrates on upper surface.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; it is equal to replacement according to technical scheme and inventive concept thereof or is changed, all should be encompassed within protection scope of the present invention.
