[0002] Etched honeycomb ceramic heating core is a heating element with ceramic as the base material. It is widely used in various small household appliances and industrial equipment. Etched honeycomb ceramic heating core is generally composed of heating wire and ceramic shell frame.

[0003] The working principle of the etched honeycomb ceramic heating core is that when the heating wire is energized, the current passing through the heating wire will generate resistance heat, which will then dissipate through the ceramic outer shell to achieve the heating effect.

[0004] Currently, the existing etched honeycomb ceramic heating cores generally have a closed ceramic shell frame. The heat generated by the heating wire can only be dissipated through heat conduction through the ceramic shell frame. This closed heat conduction greatly reduces the efficiency of heat transfer from the etched honeycomb ceramic heating core to the outside. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an etched honeycomb ceramic heating core.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an etched honeycomb ceramic heating core, including a ceramic outer frame, which is composed of a bottom plate and a top plate. A central axis fixing rod is fixed between the bottom plate and the top plate. The bottom plate has a bottom honeycomb slot, and the top plate has a top honeycomb perforation. A conductive rod is inserted into the ceramic outer frame. The conductive rod is provided with a heating wire and a mounting screw groove. A conductive plate is provided at the top of the conductive rod, and a mounting stud is provided on the conductive plate.

[0008] The mounting stud is provided with a rotating cap handle, and the rotating cap handle is provided with a finger pressure side block;

[0009] The mounting stud has an anti-loosening bullet with rounded corners, and the finger pressure side block has an anti-slip layer.

[0010] Furthermore, the bottom plate and the top plate are generally disc-shaped structures, and the central shaft is located at the vertical center of the bottom plate and the top plate.

[0011] Furthermore, the conductive rod passes vertically through the top honeycomb perforation and is inserted into the bottom honeycomb slot, the top end of the conductive rod is higher than the top plate, and the heating wire is spirally arranged along the outer wall surface of the conductive rod.

[0012] Furthermore, the conductive rod, bottom honeycomb slot, and top honeycomb perforation are grouped together, forming a total of ten groups arranged in a circle.

[0013] Furthermore, the mounting screw groove is formed at the top of the conductive rod, the mounting stud passes through the conductive plate and is threadedly connected to the mounting screw groove, and the lower end face of the conductive plate is in close contact with the top end face of the conductive rod.

[0014] Furthermore, the anti-loosening bullet is located at the lower end of the mounting stud, the lower end of the anti-loosening bullet is in contact with the mounting screw groove, and the rounded corner is provided along the outer corner of the lower end of the anti-loosening bullet.

[0015] Furthermore, the top view of the acupressure side block is a semi-circular structure with eighteen circumferentially arranged blocks, and the anti-slip layer is uniformly coated along the outer wall surface of the acupressure side block.

[0016] The etched honeycomb ceramic heating core proposed in this utility model has the following advantages:

[0017] 1. This utility model achieves an exposed installation structure for the heating wire by setting a bottom plate and a top plate, with a central fixing rod between them, and a conductive rod structure with the central fixing rod. This allows the resistive heat generated by the heating wire to be directly heated to the outside, avoiding the significant reduction in the heating efficiency of the etched honeycomb ceramic heating core to the outside due to closed heat conduction.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5 An etched honeycomb ceramic heating core includes a ceramic outer frame 1, which is composed of a bottom plate 2 and a top plate 3. A central axis rod 4 is fixedly arranged between the bottom plate 2 and the top plate 3. A bottom honeycomb slot 21 is opened on the bottom plate 2, and a top honeycomb perforation 31 is opened on the top plate 3. A conductive rod 5 is inserted into the ceramic outer frame 1. A heating wire 51 and a mounting screw groove 52 are provided on the conductive rod 5. A conductive plate 6 is provided on the top of the conductive rod 5, and a mounting stud 8 is provided on the conductive plate 6.

[0027] The mounting stud 8 is provided with a rotating cap handle 7, and the rotating cap handle 7 is provided with a finger pressure side block 71;

[0028] The mounting stud 8 has an anti-loosening bullet 81, the anti-loosening bullet 81 has a rounded corner 82, and the finger pressure side block 71 has an anti-slip layer 72.

[0029] The bottom plate 2 and the top plate 3 are generally disc-shaped structures. The central axis fixing rod 4 is located at the vertical center of the bottom plate 2 and the top plate 3. The bottom plate 2, the top plate 3, and the central axis fixing rod 4 are all made of ceramic.

[0030] The conductive rod 5 passes vertically through the top honeycomb perforation 31 and is inserted into the bottom honeycomb slot 21. The top of the conductive rod 5 is higher than the top plate 3. The heating wire 51 is spirally arranged along the outer wall of the conductive rod 5. The heating wire 51 is a dry-burning type heating wire. In the prior art, the conductive rod 5 is made of nickel-plated copper material, which has good conductivity and corrosion resistance, and high strength without deformation.

[0031] The conductive rod 5, the bottom honeycomb slot 21, and the top honeycomb perforation 31 form a group, and there are a total of ten groups arranged in a circle.

[0032] The mounting slot 52 is opened at the top of the conductive rod 5. The mounting stud 8 passes through the conductive plate 6 and is threadedly connected to the mounting slot 52. The lower end face of the conductive plate 6 is in close contact with the top face of the conductive rod 5. The conductive plate 6 is made of red copper. When energized, the conductive plate 6 can realize the current flow effect of the inner and outer conductive rods 5 and the heating wire 51, thereby achieving the effect of heating.

[0033] The anti-loosening spring 81 is located at the lower end of the mounting stud 8. The lower end of the anti-loosening spring 81 is in contact with the mounting thread groove 52. The anti-loosening spring 81 is made of high-elastic rubber material, which is wear-resistant and durable. When the mounting stud 8 is threaded and locked with the mounting thread groove 52, the anti-loosening spring 81 will be in contact with the mounting thread groove 52. The anti-loosening spring 81 will generate a vertical rebound force when squeezed. This vertical rebound force acts on the mounting stud 8, realizing the thread anti-loosening action.

[0034] The rounded corner 82 is set along the outer corner of the lower end of the anti-loosening bullet 81, which ensures the smooth vertical insertion of the anti-loosening bullet 81 into the mounting screw groove 52.

[0035] The top view of the acupressure side block 71 is a semi-circular structure with eighteen blocks arranged in a circle, which makes it convenient for the fingers to grip and rotate the cap handle 7.

[0036] The anti-slip layer 72 is evenly coated along the outer wall of the acupressure side block 71. The anti-slip layer 72 is a silicone rubber coating, which has damping friction and improves the damping and anti-slip performance of the fingers when gripping and rotating the acupressure side block 71.

[0037] Operating mode: Each set of conductive rods 5 and heating wires 51 are electrically connected to an external power source through a preset power line. After being powered on, the heating wires 51 generate current and heat up. Since this structure is an exposed installation structure, the resistive heat generated by the heating wires 51 is directly directed to the outside for heating. This avoids the significant reduction in the heating efficiency of the etched honeycomb ceramic heating core to the outside due to closed heat conduction, thus improving the overall efficiency of the etched honeycomb ceramic heating core to the outside.

[0038] In addition, after prolonged use, a certain set of conductive rods 5 and heating wires 51 may become aged. First, turn off the power, then place your finger on the pressure side block 71 and turn the cap handle 7 counterclockwise. This will cause the mounting stud 8 to rotate counterclockwise. Through the threaded transmission between the stud 8 and the mounting screw groove 52, the mounting stud 8 can be pulled out and easily removed. The conductive plate 6 can then be easily removed. Next, pull the aged conductive rod 5 and heating wire 51 vertically upwards. Then, insert the new conductive rod 5 and heating wire 51 vertically through the top honeycomb perforation 31 and into the bottom honeycomb slot 21. Finally, the conductive plate 6 can be easily installed onto the new conductive rod 5 using the mounting stud 8. This completes the convenient and independent replacement operation, greatly improving the ease of disassembling and replacing individual conductive rods 5 and heating wires 51 from the ceramic outer frame 1 on the etched honeycomb ceramic heating core.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
