Description

Technical Field

[0001] The utility model belongs to the technical field of fan lights, and particularly relates to an ultra-thin fan blade structure. Background Art

[0002] Corresponding fan blades are provided on fans and fan lights. The fan blades are driven by a fan motor to rotate to form natural wind to achieve a cooling effect. The shape of the fan blades is the key factor determining the performance of the fan blades. The fan blades in the prior art have a relatively large height. When installed and used, a relatively large space is required and they cannot be made ultra-thin. When combined with a lamp, the entire lamp needs to be made thicker, and the effect of an ultra-thin lamp cannot be achieved. Therefore, the applicability and practicability are limited. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an ultra-thin fan blade structure with reasonable structural settings and strong practicability.

[0004] The technical solution for achieving the purpose of the utility model is an ultra-thin fan blade structure, which includes an installation ring and a plurality of blades arranged on the installation ring. The height of the blades is 27 - 32 mm, and the height of the installation ring is less than the height of the blades.

[0005] The angle between the bottom edge of the blade and the bottom surface of the installation ring is 38° - 42°, and the angle between the top edge of the blade and the bottom surface of the installation ring is 12° - 18°.

[0006] Further preferably: A circular bottom plate is integrally formed on the bottom surface of the installation ring, and a plurality of installation holes are fixed on the circular bottom plate.

[0007] Further preferably: The diameter of the installation ring is 370 - 390 mm.

[0008] Further preferably: The blades are integrally formed on the outer ring surface of the installation ring.

[0009] Further preferably: The blades are fastened or fixed to the outer ring surface of the installation ring by screws.

[0010] Further preferably: The number of the blades is 3 - 9.

[0011] The utility model has positive effects: The structural settings of the utility model are reasonable. The height of its blades is 27 - 32 mm, and the height of the installation ring is less than the height of the blades. Therefore, after assembly, the overall height of the fan blade structure is small. When used in combination with a lamp, the lamp can be made thinner. Moreover, the angles between the blades and the bottom surface of the installation ring are reasonably set, which is beneficial to improving the air intake and blowing effects. It has strong applicability and good practicability. Brief Description of the Drawings

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment

[0018] See Figures 1 to 2 As shown, a structure of an ultra-thin fan blade includes a mounting ring 1 and a plurality of blades 2 arranged on the mounting ring. In this embodiment, the mounting ring and the blades can be plastic structures or metal structures. And in actual application, the height of the blade is 27 - 32 mm, and the height of the mounting ring is less than the height of the blade. Therefore, after processing, the overall structure can be made thinner, which is suitable for the use of ultra-thin fan lights, and at the same time, the effectiveness and stability of air intake can be ensured. And in actual application, the angle between the bottom edge of the blade and the bottom surface of the mounting ring is 38° - 42° (i.e., the inner edge angle), and the angle between the top edge of the blade and the bottom surface of the mounting ring is 12° - 18° (i.e., the outer edge angle). Through the above angles, the effectiveness and stability of blowing can be improved.

[0019] In actual application, a circular bottom plate 3 is integrally formed on the bottom surface of the mounting ring, and a plurality of mounting round holes 4 are fixed on the circular bottom plate. Through the above structure, the mounting stability and reliability with the fan motor can be improved, and it is also beneficial to improve the convenience of disassembly and assembly. In actual application, the diameter of the mounting ring is 370 - 390 mm. In actual application, the blade is integrally formed on the outer ring surface of the mounting ring. At the same time, in this embodiment, the blade can also be buckled or fixed on the outer ring surface of the mounting ring by screws. The number of the blades is 3 - 9. The number can also be adjusted according to needs to meet the usage requirements in different situations, and it has strong practicability.

[0020] The utility model has positive effects: The structure of the utility model is reasonably arranged. The height of its blades is 27 - 32 mm, and the height of the mounting ring is less than that of the blades. Therefore, after assembly, the overall height of the fan blade structure is small. When used in cooperation with a lamp, the lamp can be made thinner. Moreover, the angle between the blade and the bottom surface of the mounting ring is reasonably set, which is beneficial to improving the air intake and blowing effects, with strong applicability and good practicability.

[0021] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the instruction manual, they can also be directly processed without any doubt according to the existing technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.

[0022] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or variations derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
