[0006] As a preferred solution of the present utility model, the impeller body is a trumpet-shaped structure.

[0007] As a preferred solution of the utility model, eighteen groups of streamlined guide plates are provided, wherein the eighteen groups of streamlined guide plates are evenly arranged on the back side of the impeller body.

[0008] As a preferred solution of the utility model, the angle between the streamlined guide plate and the tangent line of the edge of the impeller body is 51 degrees, and the maximum diameter of the impeller body is 800 mm.

[0009] As a preferred solution of the utility model, the protective blades are provided with 7 layers, wherein the 7 layers of protective blades are evenly arranged on the back side of the impeller body.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] In the utility model, the impeller body, the streamlined guide plate, the protective blades in the circulating air fan blades are used to utilize the interaction between the impeller body, the streamlined guide plate, the protective blades and the various components to enable the air to circulate. As a result, when the circulating air fan blades are in use, the air can circulate when the circulating air fan blades rotate, thereby greatly improving the use effect of the device.

[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings, and several embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0017] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0019] For example, please refer to Figure 1-2 , the utility model provides a technical solution:

[0020] A circulating air fan blade comprises an impeller body 1, a plurality of streamlined guide plates 2 are connected to the back of the impeller body 1, a plurality of protective blades 3 are arranged on the back of the impeller body 1 and on the streamlined guide plates 2, and a gourd-shaped connecting hole 4 and a bolt hole 5 are opened at the center of the impeller body 1;

[0021] In this embodiment, reference Figure 1 and Figure 2 The air intake direction is vertical downward, and the other side is vertical upward. It is fixed on the ceiling. There is a fixed installation distance of 20 cm between the ceiling and the fan. When it is working, the air below is sucked into the impeller, and at the same time, it is split and cut under the action of the streamlined guide plate 2, accelerated, and discharged from all sides, circulated downward along the room wall, and sucked in again. The air is cooled by using the flow rate of the inhaled air that is lower than the flow rate of the discharged air, so as to cool the air in the room;

[0022] Furthermore, the impeller body 1 is a trumpet-shaped structure, and eighteen groups of streamlined guide plates 2 are provided, wherein the eighteen groups of streamlined guide plates 2 are evenly arranged on the back of the impeller body 1, and the angle between the streamlined guide plates 2 and the tangent of the edge of the impeller body 1 is 51 degrees.
