Specifically, the curve equation of the main vein 4030 is related to the equation of each segment of the leaf edge 402, because the main vein 4030 is located on the central axis of the sweep blade 400, and the contour of the sweep blade 400 is determined by the curve equation of the blade edge 402. According to the curve equation of the leaf edge 402 in the above embodiment, the curve equation of the main vein 4030 is divided into three sections, counting from top to bottom. The first section is the curve equation of the first leaf edge 4021 and the third leaf edge 4023 Average, the second segment is the average of the curve equations of the first leaf edge 4021 and the fourth leaf edge 4024, and the third segment is the average of the curve equations of the second leaf edge 4022 and the fourth leaf edge 4024. It should be noted that the above-mentioned segmentation of the curve equation of the main vein 4030 is only based on the curve equation of the leaf edge 402 in the above embodiment.

For example, the equation for establishing the branch pulse 4031 in the above Oxy coordinate system is The specific parameters of the equation can be obtained, and based on the equation established in other coordinate systems, the equation form can be simplified as the best; after the curve equation is established, the curvature of the curve is established accordingly. Refer to Leaf Edge 402 for the specific process. The process of calculating curvature by the equation will not be repeated here.

Next, the equation form corresponding to each branch 4031 will be explained. For example, the curve equation of branch 4031 extending from the middle section of main vein 4030 is mostly linear and parabolic, and the part near leaf tip 401 or petiole 404 from main vein 4030 The curve equations of the extended branch veins 4031 are mostly round or elliptical. This arrangement makes the shape and structure of the vein 403 closer to the vein shape in nature, imitating the biological structure to achieve the improvement of the wind guiding ability of the sweep blade 400, not only saving The design and production costs also improve the comfort of users.

The air conditioner also includes connecting rods, buckles, positioning blocks, rotating shafts and other parts that cooperate with the sweeping blades and other parts necessary for the operation of the air conditioner.

The air conditioner designs the sweeping blades as a bionic blade structure, so that the sweeping blades can more effectively control the wind direction, play a better air guiding effect, increase the user comfort, and at the same time help the sweeping blades Improved aesthetics is helpful to enhance user perception; at the same time, by setting buckles, positioning blocks and rotating shafts on the support plate where the sweep blades are installed, the smooth positioning, fixing and disassembly process of the support plate and sweep blades can be realized, which helps The stability of the sweeping blades at the same time enables fewer manual operations to be performed when the sweeping blades need to be replaced or cleaned, saving labor costs, preventing parts damage caused by frequent operations, and improving the overall performance of the air conditioner.

The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the present disclosure. Within the scope of protection.
