New Description·· [The field of new technology] _ is related to a kind of rectification induced wind, which is related to one eye-Γ+ more ping and hundred air supply distance... Increase the airflow speed and extend the structure of the rectifying embroidery fan. [Prior Art] The first item in the market is that the fan 1 on the market today includes at least a fan net 10 and an electric fan, and the electric fan 1 is driven by a fan placed in the fan net 10 to drive The motor 12 in which the blade rotates. Going to the Emperor π household as follows, because the fan leaf ιι_ is produced by the flat pole in the 荩 sign # 々丨 l l although the pressure is balanced from the direction of the ten 仃 茱 茱 , , , , , , , , , , , It is also empty with the surrounding, so the human body must rely on...'•The wind is scattered around the wind to feel its wind/, and the fan structure is induced. 1 - The distance can be seen from the above example. The fan is more than 2, 3~ from the human body. : There is a shortcoming of wind shortage in the crane. When the wind system is improved, the fan is obviously smaller. The transmission is vice Τ' == The fan blade speed will lead to high power consumption and high noise induced fan knot: :=Source:: is a coil motor, and nowadays the rectification of the Erxizhang private fan is protected by a plurality of _$, and today’s stricter Anxiang Bu, 隹τ, Tian Hou, Meng,, 糸The composition, the field, the end of the door, _ not allowed, the distance between the wires is very small, so the wind is attenuated, and it is easy to produce noise. In addition, the thin wall of the 19512 5 M300023 fan is close to the middle and the fire! The hoist is designed to be assembled so that the wires are more densely arranged, long-term t + long, and the valleys are easy to accumulate dust or cotton wadding. θ Therefore, how to improve the above various shortcomings is a problem that needs to be considered today. [New content] The deficiencies of the above-mentioned conventional technologies, the purpose of this creation is to provide a rectifying induction fan structure that can prolong the wind. I also created a rectification-induced fan structure with a diversion section that allows the fan to achieve high wind speeds at lower speeds to save energy. Another object of the present invention is to provide a rectification-inducing fan structure having an air inlet portion for directing all airflow of the fan to concentrate the airflow to raise the surface wind speed. A further object of the present invention is to provide a rectification-inducing fan structure having parallel flow guiding portions and a net having a planar structure to enhance the flow direction of the induced I gas stream. In order to achieve the above object, the present invention provides a rectification-inducing fan structure, which comprises at least: a plurality of blades for performing a rotary motion to generate an air flow; a first cover covering the rear of the blade; and a second cover The body covers the ridge of the blade, and has an air inlet portion with a rounded guiding surface and a flow guiding portion connected in parallel with one end of the air inlet portion, so that the second cover body has a bell-shaped appearance, the air inlet portion is configured to be fitted to the first cover body such that the fan blade is placed between the first and a cover bodies, and the airflow is merged to the flow guiding portion, and The deflector directs the airflow in parallel in the same direction, and increases the wind speed and 6 19512 M3 00023 * to extend the airflow distance of the airflow. The rectification-induced fan structure of the present invention can be applied to vertical fans, wall-hanging feathers, and rotating ceiling fans that are also mounted on the ceiling. The first and second covers can be plastic-covered in the same day and can be fitted to each other in a tool-free manner. The blade system is coupled to a rotary power unit for rotational movement. The flow guiding portion is connected to one end of the small diameter of the air inlet portion, and the inlet γ has a large opening from one end for fitting into the first cover body, and the wind inlet portion is slanted and guided by the wrong shape. The surface reduces the energy lost by the airflow due to limitations. The guide is in the shape of a ring of uniform diameter. The principle of action is to isolate the initial gas generated by the blade from the surrounding atmosphere and leave only the opening that can be straight into the air. Therefore, the airflow can be prevented from being prematurely balanced with the surrounding air. The wind speed is quickly reduced, and the airflow is rectified by the flow guiding portion, which can have a high degree of collimation. Therefore, even after leaving the flow guiding portion, the wind speed of the airflow is not as high as that of a conventional fan that is not rectified and directly uses the net to blow out. Fast decay, thus increasing the wind speed and extending the air supply distance.曰! έ海弟-The cover has a first net for introducing air, and the second cover has a second net connected to the end of the flow guiding portion for supplying air, the first net and the first The second protection net system has a planar structure parallel to the wind direction and the wind direction, so as to reduce the resistance to the air flow, and the planar structure is also less likely to adhere to impurities such as cotton. Compared with the rectification-induced fan structure of the prior art, the wind speed is rapidly attenuated by the direction of the wind with the distance. The rectification-inducing fan structure of the present invention has a flow guiding portion that can concentrate the airflow portion and the guiding airflow, and The airflow is introduced into the flow guiding portion by the air inlet portion, and the airflow through the air guiding portion has a high standard 19512 7 M300023. The indoor air circulation straightness and the preferred wind speed are increased to increase the propagation distance effect. Moreover, the conventional technology must increase the rotational speed to make the wind propagate more sturdy. The rectifying fan structure of the present invention can achieve the distance from the conventional technology with a large rotating speed by using the diversion portion. - Off, so you can save power. Moreover, the rectifying material fan structure # of the present invention has less resistance than the conventionally-constructed guide fan structure, so that the noise generated by the airflow can be reduced, and the aforementioned low rotational speed can be achieved. The characteristics of high wind speed, the motor noise generated by the rectification-induced fan structure of this creation
