Further, the battery power supply system is a rechargeable battery.

Further, the wireless thermal insulation board also includes a heat insulating layer for preventing heat from the electric heating component from being transferred to the battery-powered system, and the heat-insulating layer is embedded between the electric heating component and the battery-powered system.

Further, the material of the heat insulation layer is heat insulation cotton.

Further, the casing includes a frame, and the frame surrounds the outer peripheral edges of the panel and the heat insulation layer.

Further, a bottom box is provided at the bottom of the casing, the battery power supply system is arranged in the bottom box, and the bottom box is detachably connected to the frame.

Further, the panel is a black crystal panel.

Further, the wireless heat preservation board also includes a temperature control switch circuit for controlling the temperature of the panel within the range of 0-90 degrees.

Further, the wireless thermal insulation board also includes a power protection system, and the power protection system is electrically connected with the battery power supply system and the electric heating component.

Further, the wireless heat preservation board also includes a power indicator light, which is electrically connected between the battery power supply system and the electric heating component, and partially protrudes from the casing.

Compared with the prior art, the utility model has the beneficial effect that a battery power supply system is arranged inside the wireless thermal insulation board of the utility model, and the battery power supply system can supply power to the electric heating components without connecting a power line to an external power source. Therefore, the wireless The insulation board can be moved arbitrarily, which is convenient for users to use in daily life, banquets and other occasions. At the same time, since the wireless thermal insulation board no longer depends on a fixed power source, it is easy to carry and can be used outdoors. In addition, the wireless thermal insulation board does not have a power cord extending out of the thermal insulation board, so it can be embedded in various electric heating products and has a wide range of applications.

detailed description

In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1 to Figure 3, it is a preferred embodiment of the utility model, a wireless heat preservation board, including a shell 1, a panel 2, an electric heating component 3, a battery power supply system 4, a heat insulation layer 5, a temperature control Switch circuit, power protection system (all not shown in the figure) and power indicator light 6. Wherein, the casing 1 includes a stainless steel frame 11 and an aluminum alloy bottom box 12 .

Specifically, the above-mentioned panel 2 is a black crystal panel, which is arranged on the heating element 3 and covered with a stainless steel frame 11 . The battery power supply system 4 is a rechargeable 24V lithium battery power supply system, which is embedded in the casing 1 and electrically connected with the electric heating component 3, the temperature control switch circuit and the power protection system. The material of the heat insulation layer 5 is heat insulation cotton, which is embedded between the electric heating component 3 and the battery power supply system 4 , which can prevent the heat of the electric heating component 3 from being transferred to the battery power supply system 4 .
