DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1 - Figure 4 As shown, the three-dimensional quick-heating structure of the ceramic electric stew pot includes an aluminum pot 1, a heat-generating belt 2 and a mica heating sheet 5. A base 10 is clamped at the bottom of the aluminum pot 1, and the base 10 is used to support the aluminum pot 1 and to heat the bottom of the aluminum pot 1. The base 10 is sealed and the sealing member is used to fix the heating member, and the heat-generating belt 2 is arranged on the outer surface of the aluminum pot 1 through a buckle, wherein the heat-generating belt 2 surrounds the outer surface of the aluminum pot 1, so that the heat-generating belt 2 transfers heat to the outer surface of the aluminum pot 1, and a heating film 3 is arranged below the heat-generating belt 2, wherein the curved area in the aluminum pot 1 is used to bond with the heating film 3, and the heating film 3 is when current passes through the conductive layer, the electrical energy is converted into thermal energy, and the heat is transferred to the surrounding medium through heat conduction, and a conductive material such as metal powder or special ink is added therein. This film heater has good flexibility and can be bent to fit surfaces of different shapes. Therefore, it is widely used in occasions that require uniform heating. The heat-generating belt 2 is bonded with heat-insulating cotton 4 on the side away from the aluminum pot 1. The porous fiber structure in the heat-insulating cotton 4 can capture air or other gases while keeping warm, thereby forming a heat-insulating layer to fill the cavity around the outer surface of the aluminum pot 1. Therefore, when the aluminum pot 1 is heated, the heat received by the aluminum pot 1 can be avoided through the heat-insulating cotton 4, thereby reducing heat dissipation. A mica heating sheet 5 is installed at the bottom end of the aluminum pot 1. The mica heating sheet 5 is an electric heating element, in which mica is used as a base material for making the heating sheet. By coating the mica sheet with metal conductive materials, such as silver, nickel and copper, etc., and taking advantage of its own good thermal conductivity: due to the high thermal conductivity of mica itself, electrical energy can be quickly converted into thermal energy and evenly transferred to the heated object. The mica material itself can remain stable at a relatively high temperature, so that even in a high temperature environment, the electrical insulation performance of the mica material helps to prevent current leakage, thereby improving the safety of use. Ceramic fiber cotton 6 is placed under the mica heating sheet 5, wherein the ceramic fiber cotton 6 can withstand extremely high temperatures in a short time to prevent the heat diffused by the mica heating sheet 5 from affecting the base 10 below, and a heat insulation cover 7 is placed under the ceramic fiber cotton 6. The function of the heat insulation cover 7 is to cooperate with the ceramic fiber cotton 6 to reduce the heat loss while reducing the heat transfer of the mica heating sheet 5 to a position away from the aluminum pot 1, so that the heat generated by the mica heating sheet 5 will not affect the base 10.

[0023] A mica baffle 9 is arranged below the heat insulation cover 7, and the placement groove 901 arranged on the mica baffle 9 is used to fill glass fiber wool 8 to reduce the weight of the mica baffle 9 while enabling the mica baffle 9 to cooperate with the glass fiber wool 8 to block the heat transferred by the mica heating sheet 5. A placement groove 901 is arranged at the top of the mica baffle 9, and plug holes 12 are arranged at the centers of the glass fiber wool 8 and the mica baffle 9. The plug holes 12 are used to cooperate with the fasteners 11 for fixation, and glass fiber wool 8 is placed at the centers of the heat insulation cover 7 and the mica baffle 9.

[0024] A first assembly hole 501 is provided at the center of the mica heating sheet 5 , and a reserved opening 601 is provided at the center of the ceramic fiber wool 6 . The first assembly hole 501 and the reserved opening 601 are of the same size.

[0025] The heat insulation cover 7 includes a cover shell 701, a docking ring 702, a heat insulation groove 703 and a second assembly hole 704, and the docking ring 702 is installed on the top of the cover shell 701, and the heat insulation groove 703 is arranged on the top of the docking ring 702, and the second assembly hole 704 is placed at the center of the heat insulation groove 703, wherein the docking ring 702 is placed at the center of the cover shell 701, and the cavity around the docking ring 702 and the cover shell 701 is filled with glass fiber wool, and the heat insulation groove 703 is used to define a heat insulation area in the heat insulation cover 7, and then the heat insulation cover 7 is covered in this area. Such combination of use can reduce heat loss and improve the overall heat insulation performance.

[0026] The base 10 includes a snap-fitting piece 1001, a supporting bracket 1002 and a sealing port 1003, and the supporting bracket 1002 is arranged above the inner wall of the snap-fitting piece 1001, and the sealing port 1003 is arranged at the center of the supporting bracket 1002. The snap-fitting piece 1001 arranged in the base 10 is used to snap-fit ​​with the outer shell for wrapping the aluminum pot 1, and the supporting bracket 1002 arranged on the inner wall of the base 10 can improve the bearing capacity of the base 10 through the supporting bracket 1002.

[0027] A fastener 11 is installed at the bottom end of the base 10, and the fastener 11 includes a bolt 1101, a gasket 1102 and a fixing piece 1103. The gasket 1102 is placed below the bolt 1101, and the fixing piece 1103 is connected below the gasket 1102. The bolt 1101 of the fastener 11 passes through the second assembly hole 704 at the center of the heat insulation cover 7. When the mica baffle 9 and the base 10 are plugged in, the gasket 1102 is inserted therein for sealing. The fixing piece 1103 is used to fix the bottom end of the bolt 1101, thereby completing the fixation of the base 10.

[0028] In summary, the utility model uses an aluminum pot 1, a heat-generating belt 2 and a mica heating sheet 5 to surround the heating belt along the outer surface of the aluminum pot 1, and fix it after surrounding it once, thereby completing the fixation of the heating belt. After completing the fixation of the heating belt, the heating film 3 is fitted to the curved area of ​​the aluminum pot 1, thereby fixing the heating film 3, wherein the heat-insulating cotton 4 is surrounded once along the heating belt, thereby completing the surrounding and filling of the heat-generating belt 2, so that when the heat-generating belt 2 is working, the heat conducted by the heat-generating belt 2 to the aluminum pot 1 is increased, and the heat dissipation is reduced. The aluminum pot 1 is used to be connected to the clamping piece 1001 of the base 10 for supporting the aluminum pot 1, so as to complete the fixation of the aluminum pot 1, thereby completing the placement of the base 10. After the placement is completed, the base 1 of the aluminum pot 1 is 0 is bonded with the mica heating sheet 5, and the mica heating sheet 5 is located above the heat insulation cover 7, wherein the ceramic fiber cotton 6 is placed in the cavity reserved inside the heat insulation cover 7, wherein the ceramic fiber cotton 6 is placed at the center of the cover shell 701 and the docking ring 702, when the aluminum pot 1 is heated, the heat-generating belt 2 and the heating film 3 cooperate with the mica heating sheet 5 to heat the outer surface of the aluminum pot 1 at the same time, so that when the aluminum pot 1 is heated, the aluminum pot 1 can be heated at a faster speed, wherein the heat insulation cover 7 in the base 10 is used to place the mica heating sheet 5 while preventing the mica heating sheet 5 from transmitting heat to the base 10, and the heat insulation cover 7 is supported by the mica baffle 9, and the mica baffle 9 is placed on the support bracket 1002 in the base 10 for support.
