Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 3 shown, a ceramic heating rod convenient for connection includes a first ceramic sheet 1, a second ceramic sheet 2 and a tungsten paste heating circuit 3. Both the first ceramic sheet 1 and the second ceramic sheet 2 are annular, and the outer side surface of the second ceramic sheet 2 is attached to the inner side surface of the first ceramic sheet 1. The tungsten paste heating circuit 3 is located on the opposite side surfaces of the first ceramic sheet 1 and the second ceramic sheet 2. A plurality of limiting blocks 4 are integrally formed on the upper side surfaces of the first ceramic sheet 1 and the second ceramic sheet 2. The plurality of limiting blocks 4 are arranged in a circular array centered on the centers of the first ceramic sheet 1 and the second ceramic sheet 2. An "L"-shaped limiting hole 401 is opened in the limiting block 4. Both ends of the limiting hole 401 communicate with the upper side surface and the right side surface of the limiting block 4 respectively. A plurality of "L"-shaped connecting blocks 5 are arranged in a circular array centered on the centers of the first ceramic sheet 1 and the second ceramic sheet 2 on the lower side surfaces of the first ceramic sheet 1 and the second ceramic sheet 2. One end of the connecting block 5 away from the first ceramic sheet 1 and the second ceramic sheet 2 is integrally formed with a protrusion extending upward. The connecting block 5 can be inserted into the limiting hole 401;

[0020] Both ends of the tungsten paste heating circuit 3 are provided with energizing components located on the outer side surface of the first ceramic sheet 1.

[0021] During production, the staff prints the tungsten paste heating circuit 3 on the opposite side surfaces of the first ceramic sheet 1 and the second ceramic sheet 2 using resistor paste. Both the first ceramic sheet 1 and the second ceramic sheet 2 are made of 96% alumina tape casting green bodies. After printing the tungsten paste heating circuit 3, the staff rolls and vacuum presses the first ceramic sheet 1 and the second ceramic sheet 2, and then sinters and forms them in a reducing atmosphere at 1650 °C, and then processes them through more than a dozen subsequent processes. Finally, the production of the product is completed. After completion, the staff connects the energizing components to the ends of the tungsten paste heating circuit 3 to make the energizing components energize the tungsten paste heating circuit 3;

[0022] During use, the staff uses an external power source to energize the tungsten paste heating circuit 3 through the energizing components. Under the action of energization, the tungsten paste heating circuit 3 generates heat and conducts it to the outside through the first ceramic sheet 1 and the second ceramic sheet 2, so as to achieve the purpose of heating;

[0023] When multiple ceramic heating rods need to be connected together, the staff brings the upper and lower ends of two adjacent ceramic heating rods closer, so that the connecting block 5 is inserted between two adjacent limiting blocks 4. Then, the ceramic heating rod is rotated to insert the connecting block 5 into the limiting hole 401. Then, the upper ceramic heating rod is lifted, so that the protrusion at the end of the connecting block 5 is inserted into the hole between the limiting hole 401 and the upper side of the connecting block 5, thereby completing the connection between the ceramic heating rods and improving the convenience for the staff during use.

[0024] In this embodiment, the power-on component includes an electrode hole 101 formed in the first ceramic sheet 1 and an electrode sheet 6 disposed in the electrode hole 101. The electrode sheet 6 is clamped between the first ceramic sheet 1 and the second ceramic sheet 2, and the side surface of the electrode sheet 6 is in contact with the end of the tungsten paste heating circuit 3. An energizing wire is provided on the side of the electrode sheet 6 away from the tungsten paste heating circuit 3. During use, the two ends of the energizing wire are respectively connected to the electrode sheet 6 and an external power source. The external power source conducts current through the energizing wire into the electrode sheet 6 and then conducts it into the tungsten paste heating circuit 3 through the electrode sheet 6, causing the tungsten paste heating circuit 3 to generate heat and ensuring the reliability of the ceramic heating rod during use.

[0025] In this embodiment, the energizing wire includes a nickel wire 7 and a Teflon sleeve 8. The Teflon sleeve 8 is sleeved on the outer side of the nickel wire 7. Both ends of the nickel wire 7 extend out of the Teflon sleeve 8, and one end of the nickel wire 7 is fixedly connected to the electrode sheet 6. During use, the Teflon sleeve 8 has good corrosion resistance, insulation, and heat resistance, which can provide effective protection for the nickel wire 7 and further improve the safety of the ceramic heating rod during use.

[0026] In this embodiment, the outer diameter of the first ceramic sheet 1 is 20 mm, and the inner diameter is 19 mm. The outer diameter of the second ceramic sheet 2 is 19 mm, and the inner diameter is 18 mm.

[0027] In this embodiment, three branches are provided inside the tungsten paste heating circuit 3, and the ends of the three branches converge at one point. During use, the design of the three branches increases the area of the tungsten paste heating circuit 3 inside the ceramic heating rod, thereby improving the heating efficiency of the ceramic heating rod.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
