Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electric heating tables, specifically a flame-retardant graphene electric heating table. Background Technology With the increasing demand for heating in winter, traditional tabletop heaters are gradually being phased out due to insufficient safety and low thermal efficiency. While graphene electric heating tables, which have emerged in recent years, have rapid heating characteristics, their flame-retardant properties are weak, posing a risk of fire at high temperatures.
[0002] In existing technologies, some products achieve basic flame retardancy through ordinary tempered glass alone, but it is difficult to balance thermal conductivity and flame retardancy performance, resulting in uneven desktop temperature or material aging and failure after long-term use, leading to poor performance.
[0003] Therefore, we propose a flame-retardant graphene electric heating table. Summary of the Invention
[0004] The purpose of this utility model is to provide a flame-retardant graphene electric heating table in order to improve the flame-retardant effect of the heating table while ensuring the table heating effect.
[0005] The technical solution adopted in this utility model is as follows: A flame-retardant graphene electric heating table includes an outer rock panel, table legs, and a heating mechanism. The lower inner wall of the outer rock panel has an outer sliding groove, and a graphene heating mechanism is slidably connected to the inner surface of the outer sliding groove. The inner wall of the outer sliding groove has several mounting slots, and a support mechanism is installed inside each mounting slot. The heating mechanism includes an inner rock panel and thermally conductive silicone. The inner rock panel and the thermally conductive silicone are fixedly connected to the upper inner wall of the outer rock panel, and the thermally conductive silicone is fixedly connected to the upper surface of the inner rock panel. A high-borosilicate fireproof glass is fixedly connected to the upper surface of the thermally conductive silicone, and the lower side surface of the high-borosilicate fireproof glass is fixedly connected to the upper surface of the outer rock panel.
[0006] Furthermore, an arc-shaped extruded polystyrene board is fixedly connected to the outer side of the outer rock plate.
[0007] Furthermore, the graphene heating mechanism includes a graphene heating plate, a mica plate is fixedly connected to the lower surface of the graphene heating plate, a support plate is fixedly connected to the lower surface of the mica plate, and the outer surfaces of the graphene heating plate, the mica plate and the support plate are slidably connected to the inner surface of the outer groove.
[0008] Furthermore, a controller is installed on the upper outer side of the table leg, and the output end of the controller is electrically connected to the graphene heating plate.
[0009] Furthermore, the support mechanism includes a spring, which is fixedly connected to the inner wall of the mounting groove, and a limiting groove is fixedly connected to the end of the spring. The outer surface of the limiting groove is slidably connected to the inner surface of the mounting groove.
[0010] Furthermore, a sliding rod is fixedly connected to the inner wall of the spring near the mounting groove. After the sliding rod passes through the center of the spring, a slider is fixedly connected to it. A limit block is fixedly connected to the outer surface of the slider. An inner groove is formed on one side of the limiting groove near the spring. A slot is formed on the inner wall of the inner groove. The outer surface of the slider is slidably connected to the inner surface of the inner groove. The outer surface of the limit block is slidably connected to the inner surface of the slot.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, when using the device for heating, the graphene heating mechanism can be slid to the lower surface of the inner rock slab through the mounting groove. Then, the graphene heating mechanism is positioned and fixed using a support mechanism. The inner rock slab has a high thermal conductivity, which can evenly distribute the heat generated by the graphene heating mechanism, avoiding temperature concentration. The high borosilicate fireproof glass itself has good thermal conductivity and high temperature resistance, directly transferring heat to the tabletop as the outermost layer. Thermally conductive silicone is placed between the rock slab and the high borosilicate glass. By reducing contact thermal resistance, it ensures that the heat transfer path from the graphene heating mechanism through the inner rock slab, thermally conductive silicone, and high borosilicate fireproof glass is unobstructed, guaranteeing the heating effect of the tabletop. The high borosilicate fireproof glass forms a glassy covering layer at high temperatures, isolating oxygen and inhibiting flame spread, exhibiting excellent flame-retardant properties. Furthermore, the inner rock slab is an inorganic non-combustible material, ensuring flame retardancy while transferring heat. Through the combination of these structures, the flame-retardant effect of the heating table can be enhanced while ensuring the tabletop's heating effect. Attached Figure Description

A graphene heating mechanism 2 is slidably connected to the inner surface of the outer sliding groove 13. Several mounting slots 14 are formed on the inner side wall of the outer sliding groove 13. An arc-shaped extruded polystyrene board 11 is fixedly connected to the outer side of the outer rock plate 1. A support mechanism 5 is installed inside the mounting slots 14. The heating mechanism 3 includes an inner rock plate 31 and thermally conductive silicone 32. Plate 31 and thermally conductive silicone 32 are fixedly connected to the upper inner wall of the outer rock plate 1, and thermally conductive silicone 32 is fixedly connected to the upper surface of the inner rock plate 31. High borosilicate fireproof glass 33 is fixedly connected to the upper surface of the thermally conductive silicone 32, and the lower side surface of the high borosilicate fireproof glass 33 is fixedly connected to the upper surface of the outer rock plate 1. Specifically, when using this device for heating, the graphene heating mechanism 2 can be slid to the lower surface of the inner rock plate 31 through the mounting groove 14, and then the support mechanism 5 is used. The graphene heating mechanism 2 is positioned and fixed, and then activated for heating. The inner rock plate 31 has a high thermal conductivity, which can evenly distribute the heat generated by the graphene heating mechanism 2 and avoid temperature concentration. The high borosilicate fireproof glass 33 itself has good thermal conductivity and high temperature resistance, and as the outermost layer, it directly transfers heat to the tabletop. The thermally conductive silicone 32 is placed between the rock plate and the high borosilicate glass. By reducing the contact thermal resistance, it can ensure that the heat transfer path from the graphene heating mechanism 2 through the inner rock plate 31, the thermally conductive silicone 32, and the high borosilicate fireproof glass 33 is unobstructed, ensuring the heating effect of the tabletop. The high borosilicate fireproof glass 33 forms a glassy covering layer at high temperatures, isolating oxygen and inhibiting the spread of flames, and has a good flame-retardant effect. Moreover, the inner rock plate 31 is an inorganic non-combustible material, which can ensure the flame-retardant effect while transferring heat. Through the combination of the above structures, the flame-retardant effect of the heating table can be enhanced while ensuring the heating effect of the tabletop.
[0016] Reference Figures 1-3 The graphene heating mechanism 2 includes a graphene heating plate 21, a mica plate 22 fixedly connected to the lower surface of the graphene heating plate 21, and a support plate 23 fixedly connected to the lower surface of the mica plate 22. The outer surfaces of the graphene heating plate 21, mica plate 22, and support plate 23 are slidably connected to the inner surface of the outer sliding groove 13. A controller 4 is installed on the upper outer surface of the table leg 12, and the output end of the controller 4 is electrically connected to the graphene heating plate 21. Specifically, the controller 4 uses a single-chip microcomputer as the main control chip, model STC89C51. The mica plate 22, which is set on the lower surface of the graphene heating plate 21, is made of natural mica sheets and organic silicone through high-temperature pressing. It has excellent heat insulation, electrical insulation, and flame retardant properties, can withstand high temperatures for a long time without burning, and effectively blocks heat from being transferred to the support plate 23, thus achieving a good flame retardant effect. Through the combination of the above structures, the flame retardant effect of the heating table can be improved while ensuring the tabletop heating effect.
[0017] Reference Figures 1-3 The support mechanism 5 includes a spring 51, which is fixedly connected to the inner wall of the mounting groove 14. A limiting groove 55 is fixedly connected to the end of the spring 51. The outer surface of the limiting groove 55 is slidably connected to the inner surface of the mounting groove 14. A sliding rod 52 is fixedly connected to the spring 51 near the inner wall of the mounting groove 14. After the sliding rod 52 passes through the center of the spring 51, a slider 53 is fixedly connected. A limiting block 54 is fixedly connected to the outer surface of the slider 53. An inner groove 56 is opened on one side of the limiting groove 55 near the spring 51. A slot 57 is opened on the inner wall of the inner groove 56. The outer surface of the slider 53 is slidably connected to the inner surface of the inner groove 56. The outer surface of the limiting block 54 is slidably connected to the inner surface of the slot 57. Specifically, the graphene heating mechanism 2 is installed on the lower surface of the inner rock plate 31. Before installation, the limiting slide groove 55 is pressed to compress the spring 51. At this time, the slide rod 52 will also slide along the inner slide groove 56, and the limiting block 54 will slide along the slot 57 until the limiting slide groove 55 is completely pressed into the interior of the mounting slot 14. Then, the side of the graphene heating mechanism 2 can slide along the outer slide groove 13 until the lower surface of the inner rock plate 31 contacts the graphene heating plate 21. Then, the limiting slide groove 55 is released. At this time, under the elastic reset action of the spring 51, the limiting slide groove 55 will pop out, thereby supporting the support plate 23 from below, and thus supporting the graphene heating mechanism 2.
[0018] The implementation principle of an embodiment of a flame-retardant graphene electric heating table in this application is as follows: When using this device, connect an external power source and then install the graphene heating mechanism 2 on the lower surface of the inner rock plate 31. Before installation, press the limiting slide groove 55 to compress the spring 51. At this time, the slide rod 52 will also slide along the inner slide groove 56, and the limiting block 54 will slide along the slot 57 until the limiting slide groove 55 is completely pressed into the interior of the mounting slot 14. Then, the side of the graphene heating mechanism 2 can slide along the outer slide groove 13 until the lower surface of the inner rock plate 31 contacts the graphene heating plate 21. Then, release the limiting slide groove 55. At this time, under the elastic reset action of the spring 51, the limiting slide groove 55 will pop out, thereby supporting the support plate 23 from below, and thus supporting the graphene heating mechanism 2.
[0019] When using the heated table, the graphene heating plate 21 can be activated via controller 4. The inner rock plate 31 has a high thermal conductivity, which can evenly distribute the heat generated by the graphene heating mechanism 2, avoiding temperature concentration. The high borosilicate fireproof glass 33 itself has good thermal conductivity and is resistant to high temperatures, directly transferring heat to the tabletop as the outermost layer. The thermally conductive silicone 32 is placed between the rock plate and the high borosilicate glass. By reducing the contact thermal resistance, it can ensure that the heat transfer path from the graphene heating mechanism 2 through the inner rock plate 31, thermally conductive silicone 32, and high borosilicate fireproof glass 33 is unobstructed, ensuring the heating effect of the tabletop; the high borosilicate fireproof glass 33... The fire glass 33 forms a glassy covering layer at high temperatures, isolating oxygen and inhibiting the spread of flames, thus exhibiting excellent flame-retardant properties. Furthermore, the inner rock plate 31 is an inorganic non-combustible material, ensuring flame retardancy while transferring heat. On the other hand, the mica plate 22, located on the lower surface of the graphene heating plate 21, is made of natural mica sheets and organic silicone through high-temperature pressing, possessing excellent heat insulation, electrical insulation, and flame-retardant properties. It can withstand high temperatures for a long time without burning, effectively blocking heat transfer to the support plate 23, thus achieving a good flame-retardant effect. Through the combination of the above structures, the flame-retardant effect of the heating table can be enhanced while ensuring the table's heating effect.
