[0036] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.
[0037] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.
[0038] The following is a detailed description through specific embodiments.
[0039] like Figures 1 to 9 As shown, an embodiment of the utility model provides a heating plate, including a substrate 100, a heating layer 200, a connecting member 300 and a fixing member 400, the heating layer 200 is placed on the substrate 100, one side of the connecting member 300 is fixedly connected to the substrate 100 and is arranged on the side of the heating layer 200; a mounting surface 410 is provided on the fixing member 400, the mounting surface 410 is divided into a fixing area 411 and a connecting area 412, the connecting area 412 is fixedly connected to the other side of the connecting member 300, and the fixing area 411 is close to the heating layer 200 for fixing the heating layer 200.
[0040] Specifically, Figures 1 to 3 As shown, the portion of the fixing member 400 located in the connection area 412 is fixedly connected to the connecting member 300, and the connecting member 300 is fixedly connected to the substrate 100, so the fixing member 400 is fixedly connected to the substrate 100 through the connecting member 300. The lateral length of the fixing member 400 is longer than the lateral length of the connecting member 300, and the portion of the fixing member 400 that exceeds the connecting member 300 covers the heating layer 200, and the overlapping area of the two is the fixing area 411. The fixing member 400, the connecting member 300 and the substrate 100 form a frame, and the heating layer 200 is clamped and fixed in its frame, fixed by physical extrusion, and kept relatively still by static friction. This fixing method does not require the assistance of glue or other fixing structures, can effectively reduce the structural level and production cost of the heating plate, and can reduce the loss during heat conduction. The connecting member 300 is made of high temperature resistant glue, specifically inorganic glue or silica gel and other high temperature resistant glue. If the temperature generated by the heating layer 200 is high, it is more suitable to use inorganic glue to make the connecting member 300.
[0041] like Figure 5 and Figure 6 As shown, in this embodiment, the heating layer 200 includes a heating structure 210, and the heating structure 210 includes a first electrode 211, a heating paint 212, and a second electrode 213. The first electrode 211 and the second electrode 213 are arranged on the substrate 100, and the heating paint 212 is arranged between the first electrode 211 and the second electrode 213, and the heating paint 212 is electrically connected to the first electrode 211 and the second electrode 213 respectively. The heating paint 212 is a resistive material such as a graphene carbon-based heating paint, which can convert the current flowing in the heating paint 212 into heat and dissipate it. A path is formed between the first electrode 211, the heating paint 212, and the second electrode 213, and the current flows in the heating paint 212. The heating paint 212 converts electrical energy into thermal energy, and transfers the heat from the direction toward the substrate 100 to the heating plate. After the first electrode 211 and the second electrode 213 are powered on, a large amount of graphene in the heating coating 212 can rub and vibrate against each other under the action of the electric field, and the graphene microcrystals perform "Brownian motion" under the action of the electric field, generating a large amount of heat, thereby realizing the conversion of "electrical energy to thermal energy", and can emit far infrared rays with a wavelength of about 5-25 microns. Infrared rays in this band are easily absorbed by the human body. When the human body receives infrared rays for heating, it can promote blood circulation in the human body and achieve the effect of health care. Graphene heating has high reliability, good pressure resistance, plug-in and heat-up when powered on, uniform heating, rapid heat dissipation, and good infrared radiation effect. The substrate 100 is a flat plate made of glass or other materials, and heat and / or light can penetrate the substrate 100 and be emitted.
[0042] like Figure 2 , Figure 3and Figure 7 As shown, in this embodiment, the heating layer 200 also includes an insulating member 220, which covers the heating structure 210, and the insulating member 220 is arranged between the heating structure 210 and the fixing member 400, and the fixing area 411 is close to the insulating member 220. Specifically, the insulating member 220 is a mica board, which has good insulation performance. In addition, the mica paper can also withstand high temperatures of about 800°C and can be used as a good flame retardant material. Since the insulating member 220 and the substrate 100 squeeze the heating structure 210 from the upper and lower sides, the insulating member 220 can prevent the heating structure 210 from contacting and short-circuiting with other conductors of the heating plate or heating equipment on the one hand; on the other hand, it can also block the heat generated by the heating structure 210 (especially the heating paint 212) and reflect it back to the substrate 100 direction, thereby improving the heating effect of the heating plate. Moreover, the heating structure 210 is an irregular shape, which is usually changed into any shape according to actual needs. The flat plate-shaped substrate 100 and the insulating member 220 can well clamp and fix the heating structure 210. Optionally, the heating structure 210 can be fixed on the substrate 100 by auxiliary means such as glue, and the insulating member 220 can be fixed by the squeezing force applied from top to bottom by the fixing member 400.
[0043] like Figure 7 As shown, in this embodiment, two first conductive holes 221 corresponding to the positions of the first electrode 211 and the second electrode 213 are provided on the insulating member 220, which are used to electrically connect the power supply circuit of the heating device to the first electrode 211 and the second electrode 213. The heating plate in this embodiment is suitable for hanging on the ceiling, and the heating direction is from top to bottom. The power supply circuit of the heating device or the circuit of the ceiling passes through the first conductive holes 221 from top to bottom to contact the electrodes to supply power to the heating plate. Two first conductive holes 221 are provided on the insulating member 220, corresponding to the positions of the first electrode 211 and the second electrode 213, respectively, and the two electrodes leak out from the two first conductive holes 221 respectively. Optionally, only one long first conductive hole 221 can be provided, and the first electrode 211 and the second electrode 213 leak out from both ends of the long strip respectively.
[0044] like Figures 4 to 8As shown, the substrate 100, the first electrode 211 and the second electrode 213 of the embodiment of the utility model are all provided with second conductive holes 500, two second conductive holes 500 are provided on the substrate 100, and one second conductive hole 500 is provided on the first electrode 211 and the second electrode 213 respectively. With this design, the power supply circuit of the heating device or the circuit of the ceiling can pass through the second conductive hole 500 from bottom to top to contact the electrode to supply power to the heating plate; it can also pass through the first conductive hole 221 of the insulating member 220 from top to bottom to contact the electrode to supply power to the heating plate; the power supply method is more flexible. The fixing member 400 includes a first plate section 420, which is a planar plate-shaped structure. The area of the fixing member 400 close to the first conductive hole 221 and the second conductive hole 500 is avoided from cutting. On the other hand, the second conductive hole 500 also has the function of a welding hole. The column on the heating device passes through the second conductive hole 500 and is welded and fixed to the hole wall, and at the same time, the second conductive hole 500 is blocked to make the substrate 100 flat.
[0045] In this embodiment, two second conductive holes 500 corresponding to the positions of the two first conductive holes 221 are provided on the heating plate, and the diameter of the first conductive hole 221 is larger than that of the second conductive hole 500; one of the second conductive holes 500 penetrates the substrate 100 and the first electrode 211, and the other second conductive hole 500 penetrates the substrate 100 and the second electrode 213. The diameter of the first conductive hole 221 is larger than that of the second conductive hole 500. The advantage of this design is that the wires supplying power to the electrodes can pass through the first conductive holes 221 and directly contact the exposed electrodes when viewed from above, and other wires can pass through the first conductive holes 221 and the second conductive holes 500, penetrate the entire heating plate, and supply power in series, which is convenient for wiring arrangement.

[0048] like Fig. 9 (c) to Fig. 9 As shown in (f), in this embodiment, the fixing member 400 also includes a third plate segment 440, which is parallel to the first plate segment 420 and fixedly connected to the other end of the second plate segment 430; the mounting assembly is arranged on the second plate segment 430 and / or the third plate segment 440. Fig. 9 (a) to Fig. 9 (f) is a schematic cross-sectional view of the fixing member 400.

Specifically, the substrate 100 and the insulating member 220 are both rectangular flat plates, and the area of the substrate 100 is slightly larger than the area of the insulating member 220; the connector 300 is in the shape of a "mouth", which seals the side of the heating layer 200 in a circle, plays a role in heat insulation to prevent heat loss and electrode short circuit; the fixing member 400 is an integral frame in the shape of a "mouth", which frames the heating layer 200 all around. Optionally, the fixing member 400 can also include four long strips distributed in four directions of the substrate 100, and the four long strips are used to fix the four sides of the heating layer 200 respectively, and the length of the long strip is equal to or less than the length of the side of the substrate 100.
