DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0029] Please refer to Figures 1-3 In the embodiments of the present application, a portable electric heating coffee pot comprises a coffee pot main body 1, the bottom end of the coffee pot main body 1 is detachably connected with a heating base 2, the heating base 2 is provided with a power supply module 3 and a heating assembly, the heating assembly comprises an elastic support 4 and a thick film heating element 5 installed on the elastic support 4, and the power supply module 3 is electrically connected with the thick film heating element 5.
[0030] When the heating base 2 is connected with the coffee pot main body 1, the thick film heating element 5 is in close and elastic contact with the bottom surface of the coffee pot main body 1 under the action of the elastic support 4, so as to realize heat conduction to the coffee pot main body 1.
[0031] The insulating and heat-conducting layer 6 is arranged between the thick film heating body 5 and the elastic support 4.
[0032] In the technical scheme of the utility model,
[0033] The heating function is independent of the coffee pot main body 1, and the coffee pot main body 1 can be carried alone when the heating function is not used, so that the overall weight and volume are reduced, and portability is improved. At the same time, the modular design facilitates maintenance and replacement of the power supply module 3 and the heating assembly of the heating base 2.
[0034] The thick film heating body 5 is installed on the elastic support 4, and when the heating base 2 is connected with the coffee pot main body 1, the elastic support 4 can be self-adaptively adjusted according to the shape and position of the bottom surface of the coffee pot main body 1, so that the thick film heating body 5 is in close and elastic contact with the bottom surface of the coffee pot main body 1. This elastic contact mode ensures that the heating body can be in full contact with the pot body under different placement conditions, thereby ensuring the efficiency of heat transfer. In particular, in actual use, the bottom surface of the coffee pot main body 1 may not match the heating base 2 due to different placement surfaces, slight deformation or manufacturing tolerances, and the like. The self-adaptive adjustment can effectively compensate for various possible deviations, so that the thick film heating body 5 and the bottom surface of the coffee pot main body 1 always maintain a close and elastic contact state.
[0035] The insulating and heat-conducting layer 6 is arranged between the thick film heating body 5 and the elastic support 4, so as to ensure that heat can be smoothly conducted from the thick film heating body 5 to the coffee pot main body 1, prevent electric current from passing through the elastic support 4 to cause safety problems, and realize effective isolation of electricity and heat. Furthermore, the insulating and heat-conducting layer 6 supports the thick film heating body 5 and makes it in close contact with the coffee pot main body 1. The insulating and heat-conducting layer 6 transmits the heat generated by the thick film heating body 5 to the elastic support 4, which helps to maintain the stability of the temperature of the thick film heating body 5 and avoid local overheating. Because the heat is dispersed to the elastic support 4 to some extent, the temperature distribution of the thick film heating body 5 is more uniform, the service life of the thick film heating body 5 is prolonged, and the stability and continuity of heating of the coffee pot main body 1 are indirectly ensured. At the same time, while transmitting heat to the elastic support 4, a part of the heat is reflected or scattered back to the side where the thick film heating body 5 and the coffee pot main body 1 are in contact, thereby assisting the thick film heating body 5 in transmitting more heat to the coffee pot main body 1, reducing the invalid loss of heat between the thick film heating body 5 and the elastic support 4, improving the efficiency of heat transmission to the coffee pot main body 1, and further improving the energy utilization rate and reducing energy consumption.
[0036] In summary, the detachable heating base 2 is designed so that the coffee pot can be separated when not heated, only carrying the light coffee pot body 1, meeting the demand for portability in outdoor, travel, mobile office and other scenarios; the thick film heating body 5 itself has good heating performance, combined with the elastic support 4 to ensure close contact with the bottom surface of the coffee pot body 1, allowing heat to be quickly and evenly transferred to the coffee in the coffee pot body 1, greatly shortening the heating time, and compared with the traditional inefficient heating method, the coffee can be quickly heated to a suitable drinking temperature; due to the close and elastic contact between the thick film heating body 5 and the bottom surface of the coffee pot body 1, the heat is evenly transferred, avoiding local overheating or insufficient heating, and the coffee can be evenly heated to the greatest extent to maintain the original flavor and taste of the coffee; the setting of the insulating heat conduction layer 6 effectively isolates electricity and heat, preventing the risk of electric leakage and ensuring user safety, while the good heat conduction performance allows heat to be efficiently transferred, reducing heat loss, improving energy utilization and reducing energy consumption.
[0037] The coffee pot body 1 can be a moka pot, and the insulating heat conduction layer 6 can be aluminum nitride, aluminum oxide ceramic, etc.

[0039] The heat conduction enhancement layer 7 is made of graphene.
[0040] The selection of graphene as the material of the heat conduction enhancement layer 7 is based on its excellent heat conduction performance. Graphene has extremely high thermal conductivity and can quickly absorb and conduct heat. When the thick film heating body 5 generates heat, the heat conduction enhancement layer 7 made of graphene can quickly capture heat and efficiently transfer it to the bottom of the coffee pot body 1.
[0041] The shape of the heat conduction enhancement layer 7 is matched with the contour of the bottom of the coffee pot body 1 and the heat conduction enhancement layer 7 is matched with the thick film heating body 5 in a surface shape, ensuring the maximum contact area. This close-fitting and surface-matching structure design effectively reduces the thermal resistance in the heat transfer process. The heat generated by the thick film heating body 5 can be smoothly transferred to the heat conduction enhancement layer 7 through a large area of contact, and then quickly conducted to the coffee pot body 1, improving the overall heat transfer efficiency.

[0047] The elastic support 4 is composed of the support body 9 and the supporting leg 10 connected to the lower end of the support body 9, and the supporting leg 10 is matched with the supporting groove 11 in the heating base 2, so that the elastic support 4 can be telescopically moved in the supporting groove 11 through the elastic member 12 (such as a spring) according to the posture of the coffee pot body 1 when placed and the relative position with the heating base 2; when the coffee pot body 1 is placed on the heating base 2, if there is a certain angle deviation or position deviation, the supporting leg 10 can be automatically adjusted in position in the supporting groove 11 through the elastic member 12, so as to ensure that the thick film heating element 5 and the bottom surface of the coffee pot body 1 always maintain a good contact state.
[0048] In the embodiment of the utility model, a guide protrusion 13 is arranged on the outer side wall of the elastic supporting leg 10, a guide groove 14 is correspondingly arranged on the inner side wall of the supporting groove 11, and the guide protrusion 13 and the guide groove 14 are in sliding cooperation.
[0049] The guiding protrusion 13 is arranged on the outer side wall of the elastic supporting leg 10, and the guiding groove 14 is correspondingly arranged on the inner side wall of the supporting groove 11, the sliding cooperation of the protrusion and the groove provides a clear guiding path for the elastic supporting leg 10 to extend and retract in the supporting groove 11, so that it can be ensured that the elastic supporting leg 10 can only extend and retract along the specified direction, avoiding the shaking or random rotation of the elastic supporting leg 10 in the supporting groove 11, thereby ensuring the stability and reliability of the elastic support 4, and ensuring the butt joint of the thick film heating body 5 and the coffee pot main body 1, and further effectively ensuring the heat transfer.
