Connection components 5 are provided on both the left and right sides of the electric blanket main body 1. One end of the extension band 4 away from the electric blanket main body 1 is fixedly connected to a positioning mechanism 6.

[0025] Referring to Figure 3 , the connection component 5 includes a connection groove 51. A first limiting plate 52 is movably connected to the inner wall of the connection groove 51. The outer side of the first limiting plate 52 is fixedly connected to one end of the extension band 4 close to the electric blanket main body 1.

[0026] As a technical optimization scheme of the present utility model, by providing the connection component 5, the connection groove 51 can perform movable limiting on the first limiting plate 52, and the movable limiting of the first limiting plate 52 can perform movable limiting on the extension band 4, so as to facilitate the user to disassemble and install the extension band 4, and the use is convenient.

[0027] Referring to Figure 3 , the positioning mechanism 6 includes a second limiting plate 61. A positioning cylinder 62 is movably connected to the surface of the second limiting plate 61. A compaction plate 63 is fixedly connected to the bottom of the surface of the positioning cylinder 62.

[0028] As a technical optimization scheme of the present utility model, by providing the positioning mechanism 6, the positioning cylinder 62 can perform movable limiting on the second limiting plate 61, and the movable limiting of the second limiting plate 61 can perform movable limiting on the extension band 4, so as to facilitate the user to assemble and disassemble the extension band 4 and the positioning cylinder 62. By placing the compaction plate 63 flat on the bottom of the mattress, the mattress can position the positioning cylinder 62 and the extension band 4.

[0029] Referring to Figure 2 , a protective edge 7 is fixedly connected to the top of the electric blanket main body 1. A PVC coating cloth 8 is movably connected to the inner wall of the protective edge 7 through a zipper.

[0030] As a technical optimization solution of the present utility model, by providing the edge guard 7 and the PVC coated fabric 8, the edge guard 7 can position the PVC coated fabric 8 by using a zipper. The PVC coated fabric 8 has good waterproof and heat resistance properties, thus being able to achieve a waterproof effect.

The protrusion 12 can improve the stability between the compaction plate 63 and the bottom of the mattress.

[0035] The working principle and usage process of the present utility model are as follows: When in use, first lift the two ends of the mattress respectively and place the two positioning cylinders 62 at the two ends of the top of the bed frame, and make the compaction plates 63 on both sides of the bottom of the mattress. When the mattress is put down, the mattress can press down on the compaction plates 63 to position them. At this time, the two positioning cylinders 62 are respectively located on the left and right sides of the mattress. The positioning cylinders 62 are set to be small in volume, which can avoid too large a gap between the mattress and the bed frame. Then, lay the electric blanket main body 1 flat on the top of the mattress, and then move the first limiting plate 52 and the second limiting plate 61 so that they slide into the connecting groove 51 and the positioning cylinder 62 respectively. At this time, the elasticity of the extension belt 4 can be used to pull the left and right sides of the electric blanket main body 1 to make it in a straightened state, thus playing a role in positioning the electric blanket main body 1, avoiding the situation that the internal heating wire is damaged due to the formation of wrinkles on the surface of the electric blanket main body 1. And the elasticity of the extension belt 4 facilitates its cooperation with mattresses of different thicknesses. At the same time, the PVC coating cloth 8 can play a waterproof effect, and the wire clip 9 and the silicone sleeve 10 can play a protective role for the wire, with relatively high safety.

[0036] To sum up: For this electric blanket with high safety, by setting the extension belt 4, pulling the end of the extension belt 4 away from the electric blanket main body 1 to the bottom of the mattress and making the mattress compact it can position the electric blanket main body 1 on the top of the mattress, solving the problem that since the existing electric blanket main body does not have a positioning structure and is only laid flat on the top of the mattress, and the user is not stationary when resting and sleeping, so when the user turns over on it, it is easy to cause wrinkles on the surface of the electric blanket main body. The wrinkled electric blanket main body will squeeze the internal core component, the heating wire, which will cause the heating wire to be damaged, resulting in local overheating or short circuit of the electric blanket main body, increasing the potential safety hazard.
