Problems solved by technology

[0002] The fan blades on the existing fan generally have one direction, that is, there is only one circle of blades, and the angle of the blades is fixed, forming a columnar wind, that is, there is wind from the middle of the fan blades to the outside, and the outside wind is relatively small, resulting in The air volume in the central part of the fan is relatively large, while the periphery is small; if the fan is installed in the living room, only a few people close to the central part of the fan can blow the wind, while there is only a breeze in the place where there are many people outside; if the fan is installed in the dining room, put it on the dining table. The position of the dishes has a large air volume, but the people around the dining table feel the air volume is small, so the dishes are cold, and the people do not feel cool

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] Such as Figures 1 to 8 As shown, a multi-layer fan blade includes a central block 1, an inner ring frame 2 is arranged on the center block 1, an outer ring frame 3 is arranged outside the inner ring frame 2, the center block 1, the inner ring frame 2 and The outer ring frame 3 is arranged concentrically. The inner ring frame 2 is provided with a plurality of first blades 4 that form a circle, and between the inner ring frame 2 and the outer ring frame 3 is provided with a plurality of second blades 5 that are surrounded by a circle. There are many third blades 6 in a circle. The angle α between the line connecting the two lateral ends of the first blade 4 and the axial direction of the fan blade is 60°~70°. The best embodiment is that the angle α of the first blade 4 is 65°±2°. The preferred angle α is 65°; the included angle β betwee...

Abstract

The invention relates to a multi-layer fan blade which comprises a central block. The multi-layer fan blade is technically characterized in that an inner ring frame is disposed on the central block, an outer ring frame is disposed outside the inner ring frame, a plurality of first blade bodies defining a cycle are disposed in the inner ring frame, a plurality of second blade bodies defining a cycle are disposed between the inner ring frame and the outer ring frame, and a plurality of third blade bodies defining a cycle are disposed on the outer side of the outer ring frame. The multi-layer fanblade is simple in structure, and an air volume of the multi-layer fan blade can be conveniently adjusted to a reasonable value.

Description

【Technical field】 [0001] The invention relates to a fan blade. 【Background technique】 [0002] The fan blades on the existing fan generally have one direction, that is, there is only one circle of blades, and the angle of the blades is fixed, forming a columnar wind, that is, there is wind from the middle of the fan blades to the outside, and the outside wind is relatively small, resulting in The central part of the fan has a large air volume, while the periphery is small; if the fan is installed in the living room, only a few people near the central part of the fan can blow the wind, while there is only a breeze in the place where there are many people outside; if the fan is installed in the dining room, put it on the dining table. The location of the dishes has a large air volume, but the people around the dining table feel the air volume is small, so the dishes are cold, and the people do not feel cool. 【Content of invention】 [0003] The purpose of the present inventi...
