Description

Ceiling fan blade structure improvement

The present invention relates to a structure improvement of a ceiling fan blade, and more particularly to a technical field to which a ceiling fan blade structure is applied.

As shown in the prior art, the ceiling fan blade chuck structure is shown in Figs. 9 and 10, which is provided with a chamfer 23 between the joint end 21 of the ceiling fan blade 20 and the blade end 22, or the blade end 22 of the ceiling fan blade 20 has a twist angle. , by the inlet wind introduced from the front side of the leaf and derived from the back side, but it has the following problems:

The air guiding efficiency is poor: the joint end of the ceiling fan blade and the blade end are provided with a chamfer angle, or the blade end of the ceiling fan blade has a twist angle, so that the blade inlet air and the air guiding angle are not smooth, affecting the overall air volume, so the guide Wind efficiency is poor.

The use variability is low: the joint end of the ceiling fan blade is provided with a chamfer angle between the blade end, or the blade end of the ceiling fan blade has a twist angle, so that the blade body is matched with the wind guide and thus reduces the change pattern, so the use variability low.

This creation is based on the fact that the conventional guide fan blade structure has poor air guiding efficiency and insufficient variability in use, and is a modification of the ceiling fan blade structure of the present invention.

The main purpose of the present invention is to provide an improvement of the structure of the ceiling fan blade. The blade body is provided with a joint portion at one end thereof. The joint portion is provided with a plurality of combined perforations, and a blade body extends outwardly along the joint portion, and the blade body is combined with the blade body. The part of the blade body is arranged in a plane, and the inner side of the blade body is provided with a leaf inner side, and the inner side of the leaf body is arranged in a plane plane, and the far side joint portion of the blade body is provided with a leaf outer side, and the outer side of the leaf leaf is provided with a leaf front end and a leaf rear end. The front end of the leaf is arranged in an arc curved surface toward the rear end of the blade, so that the whole body of the blade body has a curved surface with continuous curvature, and the blade system is cut by the wood chip after being hot pressed, and the shape of the shape is cut according to the use requirement. The rear end of the leaf is arranged in an arc surface, so that the front end of the blade is windward, and the wind is smoothly guided to the rear end of the curved surface of the curved surface, and then is led downwards, so that the wind flow is smoothed to enhance the volume of the exported air, and the visual effect can be increased. Aesthetics, in order to achieve the efficiency of the guideline and the use of high variability.

In order to provide the Applicant with a better understanding of the structure, features and other objects of the present invention, the following detailed description is provided with the following detailed description, but the embodiments illustrated in the drawings are for illustrative purposes. It is not the only restriction on patent applications.

Please refer to FIG. 1 to FIG. 4 to illustrate the three-dimensional state, the front view state, the side view state and the side view state of the improved ceiling fan blade structure, which includes:

A blade body 10 is provided with a joint portion 11 at one end thereof, and the joint portion 11 is provided with a plurality of joint through holes 110, and a blade body portion 12 extending outwardly along the joint portion 11 is formed. The outer edge of the blade body 12 is provided with a leaf inner side 120, and the inner side 120 of the blade body is disposed in a plane-like manner, and the distal end portion 11 of the blade body portion 12 is provided with a leaf outer side 121, which is 121 A leaf front end 121A and a leaf rear end 121B are provided, and the leaf front end 121A is arranged in an arc curved surface toward the blade rear end 121B, so that the whole body of the blade body has a curved surface with continuous curvature, and the blade body 10 is subjected to hot pressing of the wood chip and then used according to the requirements of use. Cut out any shape shape;

The structure of the ceiling fan blade of the present invention is improved by the cooperation of the above structures.

Please refer to FIG. 2 to FIG. 2 to improve the front view state, the side view state, the side view state, and the blade body in the use state of the ceiling fan. The blade body edge is straight in the first embodiment. In the second embodiment, the opposite sides of the blade body have arc edges and the opposite sides of the joint portion are straight and the opposite sides of the blade body are straight edges on the opposite sides of the blade body, and the opposite sides of the joint portion are arc-shaped reference drawings. The blade body 10 is provided with a joint portion 11 and a blade body portion 12, and the blade body portion 12 and the joint portion 11 are arranged in a plane, and the blade body portion 12 is provided with a leaf inner side 120 and a inner side 120 of the blade body portion 12. The blade body portion 12 is disposed at a far side of the blade portion 12, and a leaf outer side 121 is provided with a leaf front end 121A and a leaf rear end 121B, and the leaf front end 121A is curved toward the leaf rear end 121B. The whole body of the blade body has a curved surface with continuous curvature, and the blade body 10 can be cut out of any shape according to the requirement of use due to the absence of the folding angle and the twisting of the blade (refer to FIG. 6 and FIG. 7 , Figure 8), by leaf The end 121A is arranged in an arc curved surface toward the rear end 121B of the blade, so that after the front end 121A of the blade is facing the wind, the wind entering the wind is smoothly guided to the rear end 121B of the curved surface of the curved surface, and then is led downward, so that the wind flow is smoothed to improve the volume of the air. It can also increase the visual beauty to achieve the effect of improving the efficiency of the wind guide and using the variability.

The advantages of this creation are discussed below:

1. The air guiding efficiency is improved: the front end of the blade is curved toward the rear end of the blade, so that the front end of the blade is windward, and the wind is smoothly guided to the rear end of the curved surface of the blade, and then led downward to make the wind flow smooth. The air volume is increased, so the air guiding efficiency is improved.

2. The use of high variability: the blade body has no folding angle and blade twist setting, so that the blade body after hot pressing of the wood chip can be cut out of any shape according to the needs of use, so its use variation is high.

In summary, this creation can indeed achieve the above functions and purposes, so this creation should meet the requirements of the patent application, and apply in accordance with the law.
