[0017] See also Figures 1 to 5In an embodiment of the utility model, a graphene heating plate with a connection structure includes a heating plate 1, and both sides of the heating plate 1 are sealed with comb-shaped conductive electrode sheets 4, and the pressure wire copper buckles 6 on the two conductive electrode sheets 4 are respectively connected to the monopolar power line 2 extending to the outside of the heating plate 1, and the comb teeth in the two comb-shaped conductive electrode sheets 4 are arranged in a phase and staggered arrangement, and a quick-plug connector 3 is arranged in the middle of the monopolar power line 2.

[0018] The inner part of the heating plate 1 and the outer area of ​​the comb teeth are coated with a graphene coating 5 .

[0019] By adopting the above technical solution, after the power is turned on, the graphene coating 5 generates heat to heat the heating plate 1, and the heating is more uniform.

[0020] The quick-plug connector 3 includes a socket 301, a plug 302, a connection sleeve 304 disposed inside the socket 301, a terminal head 303 fixed to one side of the connection sleeve 304 and penetrating the socket 301, an arc-shaped cavity 305 opened inside the connection sleeve 304, a connection copper column 306 disposed inside the plug 302, a plurality of arc-shaped elastic strips 307 fixed on the outer wall of the connection copper column 306, and a connection copper column 306 disposed on one side wall of the plug 302. The limiting sockets 310 on both sides, the limiting plug-in columns 308 arranged on the socket 301 and cooperating with the limiting sockets 310, the elastic rubber plugs 309 fixed inside the limiting plug-in columns 308, the spherical clamping holes 3101 opened on one side wall of the limiting plug-in columns 308 and located on one side of the elastic rubber plug 309, the limiting ball 312 movably arranged inside the spherical clamping holes 3101 and the spherical clamping holes 3101 opened on the inner wall of the limiting socket 310 and cooperating with the limiting ball 312.

[0021] Among them, the limiting plug column 308 is fixedly connected to the socket 301, the end of the connecting copper column 306 is a spherical structure, the elastic rubber plug 309 is close to the limiting ball 312, and the arc elastic strip 307 is tightly matched with the arc cavity 305 inside the connecting sleeve 304.

After power is turned on, the graphene coating 5 is heated and maintained at a constant temperature, and emits far-infrared light waves. The effect after power is turned on is shown in the figure. Figure 5 As shown, the heating is more uniform.
