Description

Technical Field

[0001] This utility model relates to the field of flexible insulation board technology, and more specifically, to a flexible insulation board that can have built-in heating wires. Background Technology

[0002] The flexible insulation board with built-in heating wire can generate heat during use to keep food warm, or it can be used as a writing board for use in cold winter weather. In the current production process, a layer of silicone sheet is placed on a flat surface, then the heating wire is placed on the silicone sheet, and then another layer of silicone sheet is pressed down so that the heating wire is sandwiched between the two silicone sheets. However, this not only results in a thicker and heavier board, but also a slower production speed. At the same time, the use of two layers of silicone sheet also significantly increases the production cost. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a flexible insulation board with built-in heating wires, which has the advantages of fast processing speed and low cost.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flexible insulation board with a built-in heating wire, comprising a silicone layer, a frame fixedly installed on the right side of the silicone layer, a protrusion fixedly installed at the bottom end of the silicone layer, a support foot fixedly installed at the bottom end of the silicone layer, and a heating wire fixedly installed in the middle of the protrusion.

[0006] As a preferred embodiment of this utility model, the connecting rope is an elastic rope, and the connecting rope is located below the frame.

[0007] In a preferred embodiment of this invention, the height of the support foot is greater than the height of the protrusion and the frame, and the support foot and the protrusion are not in contact.

[0008] As a preferred embodiment of this invention, the heating wire is encased within the protrusion and silicone layer.

[0009] In a preferred embodiment of this invention, the silicone layer, frame, protrusions, and support feet are all made of silicone.

[0010] In a preferred embodiment of this invention, the top surface of the silicone layer is a plane.

[0011] As a preferred technical solution of this utility model, the silicone layer, frame, protrusion and support foot are integrally molded.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model involves placing the heating wire inside the mold during processing and production, then placing the silicone layer inside the mold as well, and then performing molding production. By molding the silicone layer and the heating wire together, the silicone layer and the heating wire are integrally formed, resulting in uniform temperature and stable quality when the heating wire is heating. Furthermore, it eliminates the need for cumbersome production steps, has high processing efficiency, is lightweight, has a low thickness, and reduces production costs because it does not require two silicone layers.

[0014] 2. This utility model uses a connecting shaft that rotates to connect the front and rear sides of the frame, and uses a connecting rope to connect the two connecting shafts. The entire device can be hung up by the connecting rope for easy storage. Support feet are provided under the silicone layer for support during use, preventing damage to the protrusions and heating wires. Attached Figure Description

[0020] 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.

[0021] like Figures 1 to 4As shown, this utility model provides a flexible heat insulation board with built-in heating wire, including a silicone layer 1, the top surface of the silicone layer 1 is flat, a frame 2 is fixedly installed on the right side of the silicone layer 1, a protrusion 3 is fixedly installed on the bottom end of the silicone layer 1, a support foot 4 is fixedly installed on the bottom end of the silicone layer 1, and a heating wire 5 is fixedly installed in the middle of the protrusion 3.

[0022] In the preparation and production of this device, the heating wire 5 is first placed in the lower mold of the molding die, and then arranged as follows: Figure 3 As shown in the diagram, the protrusion 3 is arranged in the desired shape. Then, a silicone sheet is taken out and placed in the pre-defined position in the lower mold. At this point, the silicone sheet is positioned above the heating wire 5. The plastic film on the silicone sheet is then removed. The molding die is activated, the upper and lower molds are joined together, and the silicone sheet and heating wire 5 are heated. After being heated, the silicone sheet forms the pre-defined shape within the mold, as shown in the diagram. Figure 1 and Figure 3 The overall shape shown places the silicone layer 1 on the table and supports it with the heat-insulating support column 4, thereby insulating the bottom of the silicone layer 1. The heating wire 5 is connected to an external power source. At this time, it can be used as a cutting board and writing board, etc.

[0023] Among them, the front and rear sides of the frame 2 are rotatably connected to the connecting shaft 6, the upper and lower sides of the connecting shaft 6 are fixedly installed with positioning rings 7, and the bottom end of the connecting shaft 6 is fixedly installed with a connecting rope 8.

[0024] By rotating the connecting shaft 6 on both the front and rear sides of the frame 2 and connecting the two connecting shafts 6 with the connecting rope 8, the entire device can be hung up by the connecting rope 8 for easy storage.

[0025] Among them, the connecting rope 8 is an elastic rope, and the connecting rope 8 is located below the frame 2;

[0026] The elastic cord design of the connecting rope 8 ensures that the length of the connecting rope 8 is almost the same as the length of the frame 2 during normal use, thus preventing the silicone layer 1 from being raised on one side when the support foot 4 presses down on the connecting rope 8.

[0027] Among them, the height of the support foot 4 is greater than the height of the protrusion 3 and the frame 2, and the support foot 4 and the protrusion 3 are not in contact.

[0028] Avoid contact between the protrusion 3 and the desktop, and avoid damaging the protrusion 3 and the heating wire 5.

[0029] Among them, the heating wire 5 is wrapped in the protrusion 3 and the silicone layer 1. The silicone layer 1, the frame 2, the protrusion 3 and the support foot 4 are all made of silicone. The silicone layer 1, the frame 2, the protrusion 3 and the support foot 4 are manufactured as a single piece.

[0030] During processing and production, the heating wire 5 is first placed in the molding mold for wiring. Then, the raw silicone sheet of the silicone layer 1 is also placed in the mold, so that the heating wire 5 and the silicone layer 1 come into contact. Then, molding is carried out. By molding the silicone layer 1 and the heating wire 5 together, the silicone layer 1 and the heating wire 5 are integrally formed. This makes the heating wire 5 heat up with uniform temperature and stable quality. It also eliminates the need for cumbersome production steps, resulting in high processing efficiency, light weight, and low thickness. Furthermore, since two layers of silicone layer 1 are not required, production costs are reduced.

[0031] Working principle and usage process of this utility model:

[0032] In the preparation and production of this device, the heating wire 5 is first placed in the lower mold of the molding die, and then arranged as follows: Figure 3 As shown in the diagram, the protrusion 3 is arranged in the desired shape. Then, a silicone sheet is taken out and placed in the pre-defined position in the lower mold. At this point, the silicone sheet is positioned above the heating wire 5. The plastic film on the silicone sheet is then removed. The molding die is activated, the upper and lower molds are joined together, and the silicone sheet and heating wire 5 are heated. After being heated, the silicone sheet forms the pre-defined shape within the mold, as shown in the diagram. Figure 1 and Figure 3 The overall shape shown (excluding connecting shaft 6, positioning ring 7 and connecting rope 8);

[0033] Place the silicone layer 1 on the table and support it with the heat-insulating support column 4 to insulate the bottom of the silicone layer 1. Connect the heating wire 5 to the external power supply. At this time, it can be used as a cutting board and writing board, etc.

[0034] When not in use, place the silicone layer 1 with the right side facing up, pull up the middle of the connecting rope 8 to form a triangle between the connecting rope 8 and the frame 2. At this time, the middle of the connecting rope 8 can be hung on a nail or hook for storage.
