[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] like Figure 1 , Figure 2 , Figure 3As shown, a heating core that can be used in water includes a first ceramic layer 1 and a second ceramic layer 8, wherein tungsten paste printed circuits 3 are printed on opposite sides of the first ceramic layer 1 and the second ceramic layer 8, and the tungsten paste printed circuits 3 are arranged in a reciprocating and zigzag manner, and the first ceramic layer 1 and the second ceramic layer 8 are fired in a reducing atmosphere at 1650°C to form an integral body, and a flange 2 is glued to the left ends of the first ceramic layer 1 and the second ceramic layer 8, and two electrode holes 6 are provided on the left side of the first ceramic layer 1, and the two ends of the tungsten paste printed circuit 3 are respectively located in the two electrode holes 6, and a power-on component connected to the tungsten paste printed circuit 3 is provided in the electrode hole 6, and the heating end of the tungsten paste printed circuit 3 is located at the right end of the flange 2.
[0019] When heating the water flow, the staff can insert the right ends of the first ceramic layer 1 and the second ceramic layer 8 into the water, and start the power-on component to energize the tungsten paste printed circuit 3. Under the action of the current, the tungsten paste printed circuit 3 heats up, and conducts heat through the first ceramic layer 1 and the second ceramic layer 8 to heat the water flow. When used in water, the water flow level is located below the flange 2 to prevent the water flow from entering the electrode hole 6 and contacting the power-on component and the tungsten paste printed circuit 3 during use, thereby preventing the occurrence of leakage and improving the reliability of the heating core during use.
[0020] In this embodiment, the power-carrying component includes an electrode sheet 4 arranged in the electrode hole 6 and a wire 5 inserted in the electrode hole 6. The electrode sheet 4 is sandwiched between the first ceramic layer 1 and the second ceramic layer 8, and is fixedly connected to the first ceramic layer 1 and the second ceramic layer 8 by sintering. The upper and lower sides of the electrode sheet 4 are respectively connected to the tungsten paste printed circuit 3 and the wire 5. When in use, the end of the wire 5 located outside the electrode hole 6 is connected to the power supply. When in use, the power supply is connected to the tungsten paste printed circuit 3 through the wire 5 and the electrode sheet 4, and the tungsten paste printed circuit 3 is energized to generate heat, thereby ensuring the heating efficiency of the heating core.
[0021] In this embodiment, the outer side of the wire 5 is coated with a Teflon sleeve 7. When in use, the Teflon sleeve 7 has good corrosion resistance and electrical insulation, preventing the wire 5 from directly contacting the outside world and reducing the risk of electric shock.
[0022] In this embodiment, a glue 9 is provided at one end of the wire 5 located in the electrode hole 6. When in use, the wire 5 is fixed in the electrode hole 6 by the glue 9 and contacts the electrode sheet 4, thereby ensuring the stability of the wire 5 in the electrode hole 6 and preventing the wire 5 from escaping from the electrode hole 6.
[0023] In this embodiment, a ceramic glue 10 is provided on the side of the flange 2 that contacts the first ceramic layer 1 and the second ceramic layer 8. When in use, the flange 2 is fixedly connected to the first ceramic layer 1 and the second ceramic layer 8 through the ceramic glue 10 to prevent the flange 2 from separating from the first ceramic layer 1 and the second ceramic layer 8, and to prevent water from flowing into the electrode hole 6 through the gap between the first ceramic layer 1 and the second ceramic layer 8 and the flange 2, thereby improving the reliability of the heating core.
[0024] In this embodiment, the thickness of the flange 2 is 4.7-5.3 mm.
