[0018] The present application will be further described in combination with the drawings and specific embodiments.

[0019] Embodiment 1

[0020] As shown in the drawings, Figure 1 , Figure 2 a kind of foot warmer in the example includes heating blanket 1, heating blanket is like the laminated configuration of common heat preservation layer, heating layer, inner surface layer, heating layer is like common heating film, heating layer in the example is like through multiple heating film composition, heating film is connected with control circuit board, the gap between heating film forms crease 2, crease 2 extends along the height direction of heating blanket,Figure 1 The illustrated state can fold the heating blanket for convenient transportation and storage, etc.

[0021] In addition, the heat insulation layer is towards the outside, and a protective layer 3 can be further covered on the heat insulation layer. The protective layer is a film layer formed of a common PE material, which has a protective effect. The protective layer also has a reserved fold line.

[0022] In this example, in order to improve the stability of the heating blanket on the ground, a first connecting piece 5 and a second connecting piece 4 are respectively fixed at the head end and the tail end of the heating blanket 1. As shown in the figure, the first connecting piece 5 and the second connecting piece 4 are both rectangular bodies formed of a hard material. The end of the heating blanket 1 is inserted into the groove at the end of the corresponding connecting piece and is fixed by glue or screws. Figure 1

[0023] In this example, the end of the first connecting piece 5 is formed with a groove 9 for inserting the end of the second connecting piece 4. The groove 9 is elastically connected with a lock column 11 along the height direction of the heating blanket. Specifically, as shown in the figure, a sliding groove 10 is formed in the groove wall of the groove 9 along the height direction of the heating blanket 1. The lock column 11 is in the form of a common cylinder or square column. The head end of the lock column 11 extends out of the sliding groove 10, and the tail end is in the groove 9. The lock column and the sliding groove are gap-fitted to slide relative to each other. Figure 2

[0024] A fixed box 8 and a sliding block 7 are installed at the side surface of the first connecting piece 5. The fixed box 8 is in the form of a rectangular box body. The fixed box 8 is embedded and fixed in the groove formed at the side surface of the first connecting piece 5. The fixed box adopts a split structure. For example, the fixed box 8 includes a box body and an end cover 13 at the tail end of the box body. The sliding block 7 enters from the box opening at the tail end of the box body, and the head end of the sliding block 7 extends out of the box opening at the head end of the box body. The width of the tail end of the sliding block 7 is greater than the width of the box opening at the head end of the box body to limit disengagement. An elastic member 12 is arranged in the cavity of the box body, for example, in the form of a spring. After the sliding block is installed, the end cover covers the box opening at the tail end of the box body. The spring is between the tail end of the sliding block and the end cover 13. The end of the sliding block extending out of the box body is embedded and fixed with the lock column.

[0025] When the sliding block is moved as follows, the lock column is synchronously moved downward. As shown in the figure, a hook body 6 is fixed at the end of the second connecting piece 4. The end of the hook body is in the form of a circular arc. When the first connecting piece 5 and the second connecting piece 4 are inserted, the arc surface of the end of the hook body 6 is in contact with the peripheral wall of the lock column 11. In the process of continuing to insert, the end of the hook body presses the lock column downward to pass the lock column. After the lock column is reset, it is hooked with the hook body to limit disengagement. At this time, the heating blanket is in the form of a cylindrical body. The cylindrical body is more stable when arranged on the ground. Figure 1 When unlocked, the sliding block is pushed downward to synchronously move the lock column downward to disengage the limiting of the hook body. The second connecting piece can be disengaged from the first connecting piece.
