Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The core of the present application is to provide a rotating windmill capable of observing wind direction, so as to realize that the windmill can autonomously adjust the front of the windmill to a windward state according to the wind direction, and enhance the role of windmill toys in science and education.

[0027] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The embodiment of the present application can set an anti-slip part on the outer peripheral surface of the hollow handle 1 for easy grasping. The first connecting rod 2 can be solid or hollow, and the outer diameter of the first connecting rod 2 is smaller than the inner diameter of the hollow handle 1, so that the first connecting rod 2 can smoothly rotate in the hollow handle 1. The weather vane is composed of a wind vane 3, an arrow 4 and a tail 5. It should be noted that the area of ​​the tail 5 is larger than the area of ​​the arrow 4. The arrow 4 of the wind vane indicates the direction from which the wind blows, that is, the wind direction. For example, the arrow 4 of the wind vane points to the north, which means that the north wind blows. The embodiment of the present application does not specifically limit the shape and material of the tail 5, and the tail 5 can be made of plastic or metal. The second connecting rod 6 is fixedly connected to the wind vane 3, and the first windmill 7 and the second windmill 8 are respectively rotatably connected to the second connecting rod 6 through a rotating assembly, so that the first windmill 7 and the second windmill 8 can rotate under the action of wind force. The embodiment of the present application does not specifically limit the rotating assembly. Since the arrow 4 of the wind vane points to the direction of the wind, in order to keep the front of the first windmill 7 and the second windmill 8 facing the wind at all times, during installation, the front direction of the first windmill 7 and the second windmill 8 needs to be consistent with the direction of the arrow 4. Since the blades of the first windmill 7 and the second windmill 8 are twisted in opposite directions, when subjected to the same wind force, their own rotation directions are different, that is, one rotates clockwise and the other rotates counterclockwise.

[0030] To facilitate understanding of the blade twisting directions of the first windmill 7 and the second windmill 8, Figure 2 A schematic diagram of manufacturing a windmill provided in an embodiment of the present application, wherein the first windmill 7 is formed by rolling up the corner marked with A and connecting it to point O, and the second windmill 8 is formed by rolling up the corner marked with B and connecting it to point O.

[0031] A rotating windmill for observing wind direction provided in an embodiment of the present application comprises: a hollow handle, a first connecting rod, a weather vane, a second connecting rod, a first windmill, a second windmill and a rotating assembly; the first connecting rod is sleeved in the hollow handle, the weather vane comprises a wind direction rod and an arrow and a tail wing respectively connected to both ends of the wind direction rod, the wind vane can drive the first connecting rod to rotate in the hollow handle under the action of wind force, the first connecting rod is fixedly connected to the wind direction rod, the wind direction rod is horizontally arranged, the second connecting rod is fixedly connected to the wind direction rod, the first windmill and the second windmill are respectively rotatably connected to the second connecting rod through the rotating assembly, and the front directions of the first windmill and the second windmill are consistent with the direction of the arrow; wherein the blade twisting direction of the first windmill is opposite to the blade twisting direction of the second windmill. Under the action of wind, the weather vane rotates, driving the second connecting rod connected to the wind vane to rotate, thereby further driving the windmill to rotate in the horizontal direction, so that the windmill can autonomously adjust the front of the windmill to the windward state according to the wind direction; in addition, the wind vane is convenient for observing the wind direction, and by setting the first windmill and the second windmill with opposite blade twisting directions, it is also convenient for children to understand the influence of the blade twisting direction on the windmill's own rotation direction, thereby enhancing the role of windmill toys in science and education.

[0032] Based on the above embodiments, the rotating assembly of the embodiment of the present application includes a horizontally arranged first hollow rod 9, a second hollow rod 10 and a third connecting rod 11, the first hollow rod 9 is fixedly connected to the second connecting rod 6, the first end of the second hollow rod 10 is fixedly connected to the first windmill 7, the second end of the second hollow rod 10 is sleeved in the first hollow rod 9, the first end of the third connecting rod 11 is fixedly connected to the second windmill 8, and the second end of the third connecting rod 11 is sleeved in the second hollow rod 10.

[0033] The first hollow rod 9 in the embodiment of the present application is arranged horizontally, and the inner diameter of the first hollow rod 9 is larger than the outer diameter of the second hollow rod 10, so that the second hollow rod 10 can smoothly rotate in the first hollow rod 9; the outer diameter of the third connecting rod 11 is smaller than the inner diameter of the second hollow rod 10, and can smoothly rotate in the second hollow rod 10. The first end of the second hollow rod 10 is fixedly connected to the rotation center of the first windmill 7, and the third connecting rod 11 is fixedly connected to the rotation center of the second windmill 8. The structure of the rotating assembly in the embodiment of the present application is relatively simple and convenient to manufacture.

[0034] In addition, considering that the first windmill 7 and the second windmill 8 are arranged one after the other, the area of ​​the second windmill 8 located in front of the first windmill 7 should be smaller than that of the first windmill 7 to prevent the second windmill 8 from blocking the wind and affecting the rotation of the first windmill 7.

[0035] Furthermore, the blades of the first windmill 7 and the second windmill 8 are provided with safety reminders, such as "Children, do not run on the road!", to serve as a warning and avoid accidents. The two ends of the third connecting rod 11 are rounded and blunted to prevent the sharp tip from accidentally stabbing the child.

[0036] Based on the above embodiments, in the embodiment of the present application, the length of the second hollow rod 10 is greater than the length of the first hollow rod 9, the second end of the second hollow rod 10 extends out of the first hollow rod 9, and the second end of the second hollow rod 10 is provided with a first anti-slip block 12, the length of the third connecting rod 11 is greater than the length of the second hollow rod 10, the second end of the third connecting rod 11 extends out of the second hollow rod 10, and the second end of the third connecting rod 11 is provided with a second anti-slip block 13.

The embodiment of the present application does not specifically limit the shape of the anti-slip blocks. The peripheral surfaces of the first anti-slip block 12 and the second anti-slip block 13 are both serrated. When the second hollow rod 10 and the third connecting rod 11 rotate, the first anti-slip block 12 and the second anti-slip block 13 are also driven. The anti-slip blocks with serrated peripheral surfaces rotate, which has a certain visual effect and is more beautiful.

[0038] Based on the above embodiments, Figure 3 This is a schematic diagram of a hollow handle provided in an embodiment of the present application. Figure 4 A schematic diagram of a first connecting rod provided in an embodiment of the present application is shown as follows: Figure 3 and Figure 4 As shown, in the embodiment of the present application, an elastic anti-slip ball 201 is provided at the bottom of the first connecting rod 2 , and an anti-slip groove 101 matching with the elastic anti-slip ball 201 is provided in the hollow handle 1 .

[0039] The elastic anti-slip ball 201 in the embodiment of the present application can be made of rubber material, the shape of the anti-slip groove 101 matches the shape of the elastic anti-slip ball 201, and the diameter of the anti-slip groove 101 is larger than the diameter of the elastic anti-slip ball 201.

The embodiment of the present application does not specifically limit the shape of the base, and a circular base can be provided, and the base and the hollow handle 1 can be detachably connected. By providing the base, the windmill can be conveniently placed and can be used as an ornament.

[0041] Furthermore, a compass and anemometer can be arranged on the base. The wind vane combined with the compass can accurately know the wind direction. The anemometer can detect the wind speed, so that children can understand the relationship between the wind speed and the rotation speed of the windmill, which can further enhance the role of science and education and increase children's interest.
