[0004] Therefore, a new solution is needed to supplement the existing axial flow fan category. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wind-guiding axial flow fan.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wind-guiding axial flow fan, including a fan, wherein a first guide net and a second guide net are provided on the fan, both the first guide net and the second guide net are provided at the air outlet of the fan, and control rods are provided on both the first guide net and the second guide net, the air guiding directions formed by the first guide net and the second guide net are perpendicular to each other, and the first guide net and the second guide net have the same structure.

[0007] The present invention is further configured such that: both the first guide net and the second guide net include an outer ring, a plurality of guide plates, and a first connecting rod and a positioning rod that form a rotatable connection between the plurality of guide plates; the first connecting rod, the positioning rod and the plurality of guide plates form a parallelogram structure; and the positioning rod is fixedly connected to the outer ring.

[0008] The present invention is further configured such that: a second connecting rod is rotatably provided between the first connecting rod and the positioning rod, the second connecting rod and the flow guiding direction of the flow guide plate are parallel to each other, and the second connecting rod and the control rod are fixed to each other.

[0009] The present invention is further configured such that: a plurality of fitting pieces are fixedly provided on the outer ring, and fitting holes are provided on the outer ring, the fitting pieces and the fan, and short rods are fitted into the fitting holes.

[0010] The present invention is further configured such that the order of the first guide net and the second guide net on the fan can be interchanged.

[0011] The present invention is further configured such that: a through hole is provided on the outer ring for the control rod to pass through, and a plastic ring is provided between the control rod and the through hole.

[0012] In summary, this utility model has the following beneficial effects: the user can control the first and second guide nets installed on the fan to change the air outlet direction of the fan, which is suitable for adjusting the air outlet direction of the fan after it has been placed. At the same time, the first and second guide nets can also form an isolation between the fan and the outside world, preventing limbs from entering the rotation range of the axial flow fan blades.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] A type of axial flow fan 1, such as Figures 1-2As shown, the fan includes a blower 1, on which a first guide net 2 and a second guide net 3 are installed. Both the first guide net 2 and the second guide net 3 are located at the air outlet of the blower 1. Control rods 4 are installed on both the first guide net 2 and the second guide net 3. The airflow directions formed by the first guide net 2 and the second guide net 3 are perpendicular to each other. The first guide net 2 and the second guide net 3 have identical structures. The combination of the first guide net 2 and the second guide net 3 allows for vertical and horizontal adjustment of the airflow direction at the air outlet of the axial flow blower 1. This allows the user to directly control the first guide net 2 or the second guide net 3 via the control rods 4 when they need to adjust the airflow direction at the air outlet, thus changing the airflow direction at the air outlet. Both the first guide net 2 and the second guide net 3 include an outer ring 5, several guide vanes 6, and a first connecting rod 7 and a positioning rod 8 that rotatably connect the several guide vanes 6. The first connecting rod 7, the positioning rod 8, and several guide vanes 6 form a parallelogram structure. The positioning rod 8 is fixedly connected to the outer ring 5. The guide vanes 6 are arranged parallel to each other. The positioning rod 8 and the first connecting rod 7 are respectively located on the two long sides of the guide vanes 6. When the first connecting rod 7 is in a moving state, it will drive several guide vanes 6 to rotate synchronously, and they will remain parallel to each other during the rotation, so that the guide vanes 6 can achieve the effect of airflow guidance. A second connecting rod 9 is rotatably arranged between the first connecting rod 7 and the positioning rod 8. The second connecting rod 9 is parallel to the guiding direction of the guide vanes 6. The second connecting rod 9 is fixed to the control rod 4. The arrangement of the second connecting rod 9 forms a connection between the control rod 4 and the first connecting rod 7 and the positioning rod 8, enhancing the control effect of the first connecting rod 7 and avoiding damage to the guide vanes 6 during the control process.

[0017] A number of fitting pieces 10 are fixedly provided on the outer ring 5. Fitting holes are provided on the outer ring 5, the fitting pieces 10 and the fan 1. Short rods 11 are fitted into the fitting holes. The fitting pieces 10 are provided so that the outer ring 5 can be fixed to the fan 1 by fitting the short rods 11, or two outer rings 5 ​​can be fitted into each other to fix them, so that the first guide net 2 and the second guide net 3 can be fixed at the air outlet of the fan 1 to guide the airflow.

[0018] The order of the first guide net 2 and the second guide net 3 on the fan 1 is interchangeable. When the user needs to disassemble and install the first guide net 2 and the second guide net 3, the first guide net 2 and the second guide net 3 are allowed to be installed in any order.

[0019] The outer ring 5 has a through hole 12 for the control rod 4 to pass through. A plastic ring 13 is provided between the control rod 4 and the through hole 12. The plastic ring 13 can increase the friction between the control rod 4 and the through hole 12, and prevent the guide vane 6 from changing direction due to wind.
