[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without expending creative work are within the scope of protection of the present invention.

[0024] Existing food heating devices are mostly made of metal or glass materials. Due to their high rigidity, they take up a large space when not in use and are difficult to store.

[0025] As shown in Figures 1 and 2, in order to solve the above problems, this embodiment proposes a flexible insulation board, which mainly includes a heating pad 10 and a heating wire 20; a limiting groove 11 is formed on the heating pad 10 for the heating wire 20 to pass through, and the limiting groove 11 is evenly distributed around the heating pad 10; a power supply 30 is provided on the heating pad 10, and the end of the heating wire 20 is connected to the power supply 30; a plurality of protruding structures 40 are formed on the end surface of one end of the heating pad 10, and the height of all the protruding structures 40 is equal; the heating pad 10 and the heating wire 20 are made of flexible material.

[0026] Preferably, in this embodiment, the opening of the limiting groove 11 and the protruding structure 40 are located on the same end surface of the heating pad 10 .

[0027] Preferably, the heating wire 20 in this embodiment is made of flexible materials such as silicone heating wire 20 , carbon fiber heating wire 20 , graphene heating wire 20 , PVC heating wire 20 , and tetrafluoroethylene heating wire 20 .

[0028] Preferably, in this embodiment, the power supply 30 is provided in a raised manner, and has the same raised direction as the raised structure 40 , and the other end surface of the heating pad 10 is a planar structure.

[0029] In this embodiment, after the heating pad 10 and the heating wire 20 are assembled, the overall temperature of the heating pad 10 increases as the heating wire 20 is energized for an increasing period of time. This temperature is then transferred to the food on the heating pad through heat transfer, achieving a heat preservation effect. Furthermore, because the heating wire 20 in this embodiment extends evenly around the heating pad 10, the temperature is relatively uniform across the heating pad 10, increasing the heat preservation area of ​​the heating pad 10. This means that the heating pad 10 in this embodiment can be used to keep a large number of dishes warm.

[0030] More specifically, it also includes liquid glue 50 for encapsulating the heating wire 20 in the limiting groove 11.

[0031] Preferably, in this embodiment, liquid silicone is used to encapsulate the heating wire 20 .

[0032] In this embodiment, an opening for inserting the heating wire 20 is formed on the limiting groove 11. Therefore, the heating wire 20 can be easily separated from the opening under the action of external force. Therefore, the liquid glue 50 is used for encapsulation to ensure that the heating wire 20 is still fixed in the limiting groove 11 under the premise of the existence of external force, thereby ensuring the structural stability of the insulation board.

[0033] More specifically, a locking structure is provided inside the limiting groove 11 , and the locking structure includes two buckles 111 arranged opposite to each other; the height between the buckles 111 and the bottom of the limiting groove 11 is at least equal to the diameter of the heating wire 20 .

[0034] Preferably, the latch in this embodiment is a strip structure and is arranged along the length direction of the limiting groove 11. Preferably, but not limited to, the latch in this embodiment can also be provided with a block structure and evenly distributed in the limiting groove 11.

[0035] Preferably, the cross-section of the buckle 111 in this embodiment is semicircular, and its arc-shaped protrusions are arranged facing each other.

[0036] Preferably, in this embodiment, the distance between the buckles 111 is smaller than the diameter of the heating wire 20. However, since the heating wire 20 and the heating pad 10 are both made of flexible materials, the buckles 111 tend to expand outward when squeezed by the heating wire 20, thereby allowing the heating wire 20 to pass smoothly. When the external force disappears, the buckles 111 return to their original shape, thereby achieving an effective fixing effect on the heating wire 20.

[0037] In this embodiment, the buckle 111 achieves a first fixing effect on the heating wire 20, and then the gap in the limiting groove 11 is filled with liquid glue 50 to achieve a second fixing effect on the heating wire 20, which greatly ensures the fixed state of the heating wire 20.

[0038] More specifically, the starting end and the ending end of the limiting groove 11 are arranged in parallel, and each extends toward the outer edge of the flexible insulation board and then detours toward the center line of the heating pad 10 and is connected.

[0039] Preferably, in this embodiment, the starting end and the ending end of the limit groove 11 are located at the same short side edge of the heating pad 10, and each extends toward the long end edge. After being set along the long end edge, they detour and continue to be set in the opposite direction along the long end edge until they are connected to the starting end or the ending end.

[0040] In this embodiment, the limiting groove 11 set by the above solution can effectively ensure that it is evenly arranged along the heating pad 10, thereby ensuring that the heat of the heating wire 20 achieves the overall heating effect of the heating pad 10.

[0041] More specifically, the power supply 30 is disposed at one end of the heating pad 10 , and both ends of the heating wire 20 are connected to the power supply 30 .

[0042] More specifically, a wiring port 31 is provided on the end of the power supply 30 close to the edge of the heating pad 10 .

[0043] Preferably, in this embodiment, the connection port 31 is used to connect to an external power source and supply power to the heating wire 20 .

[0044] More specifically, the protruding structures 40 are distributed on the back side of the heating pad 10 , and a temperature-changing layer is also stacked on the front side of the heating pad 10 .

[0045] Preferably, in this embodiment, the temperature-variable layer includes a pattern, and the color of the pattern changes as the temperature rises. Preferably, but not limited to, the closer the color is to red, the higher the temperature is.

[0046] Preferably, the end of the protruding structure 40 in this embodiment is hemispherical, which can effectively ensure the supporting effect of the protruding structure 40 on the heating pad 10 and accelerate the circulation rate of air under the heating pad 10.

[0047] To sum up, this embodiment proposes a flexible insulation board, which uses a heating pad and a heating wire made of flexible material. After power is turned on, the heating pad can achieve the insulation effect, and can also be stored by rolling up. At the same time, the normal use of the heating pad can be maintained through repeated rolling and releasing.

[0048] The above-described embodiments do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the above-described embodiments shall be included in the scope of protection of this technical solution.
