[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a portable silicone heating device with a lower surface heat dissipation function, in conjunction with the accompanying drawings and embodiments, provides a more comprehensive understanding. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit its scope.

[0034] Please refer to Figures 1-7 A portable silicone heating device with a lower surface heat dissipation function includes:

[0035] The flexible body 100 includes, from top to bottom, a food contact layer 110, an aluminum heating layer 120, and a heat insulation layer 130. The food contact layer 110 is made of silicone material, and the aluminum heating layer 120 is made of aluminum heating sheet, which is attached to the bottom of the food contact layer 110.

[0036] Foot support 200, several foot supports 200 are arranged below the flexible body 100 to form a heat dissipation space below the flexible body 100;

[0037] The control box 300 has a horizontally open slot 310 on one side, and one end of the flexible body 100 extends into the slot 310.

[0038] The control circuit board 400 is disposed inside the control box 300, and the aluminum heating layer 120 is electrically connected to the control circuit board 400.

[0039] A mini blower 500 is installed inside a control box 300. The control box 300 has an air outlet 320 on the side facing the flexible body 100. The air outlet 320 is located below the flexible body 100 and connects to the heat dissipation space.

[0040] The device employs a flexible main body 100, which can be rolled up for storage. Heating is achieved using an aluminum heating layer 120, which provides faster heating, higher temperatures, better rollability, and a more uniform and dense circuit distribution compared to traditional heating wires, thus solving the problem of uneven heating in traditional heating wires. A heat dissipation space is created beneath the flexible main body 100 via feet 200. A mini blower 500 within the control box 300 actively dissipates heat into this space, preventing overheating and damage to the work surface.

[0041] Preferably, a temperature sensor is also included, which is disposed between the food contact layer 110 and the aluminothermic heating layer 120 and electrically connected to the control circuit board 400. The temperature sensor facilitates temperature control and adjustment, preventing overheating. Positioning the temperature sensor between the food contact layer 110 and the aluminothermic heating layer 120 ensures more accurate temperature readings.

[0042] Please refer to Figure 5 and Figure 6 It also includes adjustable straps 600, a flexible body 100, and a control box 300 for binding the adjustable straps 600 after curling. The adjustable straps 600 allow for better storage and optimize space utilization.

[0043] Please refer to Figure 5 and Figure 6 The adjustable strap 600 has multiple adjustment holes 610 spaced apart at one end, and a protrusion 620 at the other end. The protrusion 620 can be selectively matched with one of the adjustment holes 610. Alternatively, Velcro, adjustment buckles, elastic bands, or knotted cords can be used as needed.

[0044] Please refer to Figure 5 and Figure 6Each adjustment hole 610 includes a connected insertion hole 611 and a locking hole 612. The protruding post 620 includes a post body 621 and a protruding cap 622. The outer diameter of the protruding cap 622 is larger than the outer diameter of the post body 621. The protruding cap 622 is adapted to the insertion hole 611, and the post body 621 is adapted to the locking hole 612. The outer diameter of the protruding cap 622 is larger than the inner diameter of the locking hole 612. When the adjustable strap 600 is unfolded, the locking hole 612 is located at the end furthest from the protruding post 620. That is, the elastic restoring force of the flexible body 100 itself secures the protruding post 620 within the locking hole 612, and the protruding cap 622 prevents it from detaching, making it firmly secure and difficult to fall off. Operation is also simple and convenient.

[0045] Please refer to Figures 2-4 The control box 300 also has an air inlet area 330, which consists of several air inlet holes 331. Understandably, the air inlet area 330 should be located away from the side where the air outlet 320 is located.

[0046] Please refer to Figures 2-4 The control box 300 has a support foot 340 at its bottom, which creates an air intake space below the control box 300. The air intake area 330 is located on the bottom surface of the control box 300. The bottom air intake design is highly concealed, aesthetically pleasing, and unlikely to cause interference to the surrounding environment.

[0047] Please refer to Figure 4 and Figure 5 The control box 300 is equipped with a power supply interface 350, to which the power supply cable is plugged in. The power supply interface 350 is electrically connected to the control circuit board 400. The plug-in interface allows for better storage when not in use.

[0048] Please refer to Figure 2 and Figure 7 The foot support has a pentagonal cross-section, which improves anti-slip performance, enhances grip, and ensures safety.

[0049] Preferably, the foot support 200 is integrally formed by extending the heat insulation layer 130. The heat insulation layer 130 is generally made of heat insulation composite fiber, rubber and plastic heat insulation material, high temperature heat insulation cotton, etc., and specifically, it can be made of ceramic fiber or aluminosilicate fiber composite material.

[0050] Understandably, the aluminothermic heating layer, also known as the aluminothermic sheet, is often composed of a PI film, a heating element, and an insulating protective layer. The heating element is generally made of metal foil or metal wire, such as stainless steel, copper, or iron-chromium-aluminum. The insulating protective layer is also generally made of PI film.

[0051] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0052] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0053] In summary, the portable silicone heating device with heat dissipation function on the lower surface provided by this utility model integrates functions such as rollable storage, intelligent temperature control, rapid heating, safety and environmental protection, and efficient heat dissipation. By optimizing the structural design and functional integration, it solves the contradiction between portability, safety and practicality in the prior art and meets consumers' needs for multifunctional, lightweight and intelligent food warming equipment.
