[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0021] Combined with appendix Figure 1 , 2, 4, can be known to include two limit 1, two limit 1 between the ends of the adjustment rope structure, two adjustment rope structure between the uniform arrangement is provided with blade structure 2, blade structure 2 inside is provided with hollow area 2.1, blade structure 2 upside is provided with convex air port 2.2, blade structure 2 downside is provided with air hole 2.3, located in the top of the limit 1 side of the micro pump 3 is fixed with a side of the blade structure 2, the micro pump 3 and the air port 2.2 of the blade structure 2 at the top of the communication, the air port 2.2 top and air hole 2.3 bottom are conical structure, the surface of the conical structure is fixed with soft magnetic sheet 6, convenient for wedge connection, the distance between every two adjacent blade structure 2 is less than the maximum length of the cross section of the blade structure 2, in order to make the air port 2.2 and air hole 2.3 connection, the micro pump 3 and the external power supply are electrically connected;

[0022] In combination with the accompanying Figure 3 , can be known that the inside of the blade structure 2 is uniformly fixed with a plurality of annular ribs 2.4, which are used for frame support of the blade structure 2, the adjustment rope structure includes three ropes 4, the connecting rope 5 is fixed between the three ropes 4, which is used to drive the blade structure 2 to overturn, the ring groove 2.5 is formed on the side of the blade structure 2 near the two ends, one rope 4 passes through the ring groove 2.5, and the other two ropes 4 are located at the two ends of the ring groove 2.5. The connecting rope 5 is located in the lower side of the ring groove 2.5. By pulling one rope 4, the blade structure 2 can be driven to swing and overturn.

[0023] The working principle of the present application is as follows: when indoor heat preservation is needed, the rope 4 near the air hole 2.3 side can be pulled to drive the connecting rope 5 to move downward, thereby driving the blade structure 2 to overturn. When the blade structure 2 overturns, the convex air port 2.2 of the lower blade structure 2 is inserted into the air hole 2.3 of the upper blade structure 2, and is mutually adsorbed through the soft magnetic sheet 6.
