[0003] Patent document CN207531102U discloses an aluminum-cast ceramic heater, which discloses "a cylindrical structure composed of a pair of symmetrical arc-shaped ceramic heating plates spliced ​​together. The ceramic heating plate includes an inner ceramic heating body and an aluminum plate attached to the outer arc-shaped surface of the ceramic heating body. An electric heating rod is pre-embedded in the ceramic heating body, with both ends of the electric heating rod extending out of the ceramic heating body and passing through the aluminum plate. The aluminum plate has corresponding mounting grooves on both sides, and recesses are machined in the mounting grooves. Mounting holes are provided on the recesses, and bolt assemblies for connecting the pair of ceramic heating plates are provided in the mounting holes. This utility model has a simple structure, which makes it easy to manufacture and reduces costs. At the same time, it has a good heating effect and can be used in electric heating."

In order to reduce heat loss of the ceramic heater, an insulating shell is installed on the outside of the heating ceramic block. The inside of the insulating shell is filled with glass wool insulation material, thereby reducing heat loss during use of the heating ceramic block, making the heating efficiency of the heating ceramic block higher and the use effect better. The outer stainless steel shell of the insulating shell provides an installation position for the circuit connection components. The insulating shell also plays a protective role. The top and bottom of the insulating shell protrude from the top and bottom of the heating ceramic block, so that the heating ceramic block located on the inside will not be damaged by bumps, thus improving the safety of the ceramic heater. 2.

[0018] Please see Figure 1 , Figure 2 and Figure 3 A ceramic heater with good heat preservation effect; It includes: a first heating component 1 and a second heating component 2. The first heating component 1 and the second heating component 2 have the same structure. The first heating component 1 includes a heat insulation shell 3, a heating ceramic block 6, a top protective pad 4 and a bottom protective pad 5. The heat insulation shell 3 is installed on the outside of the heating ceramic block 6. The top of the heat insulation shell 3 is higher than the top of the heating ceramic block 6 and the bottom is lower than the bottom of the heating ceramic block 6. The top protective pad 4 is installed on the top of the heat insulation shell 3 and the bottom protective pad 5 is installed on the bottom of the heat insulation shell 3. A heating wire 7 is installed inside the heating ceramic block 6. Both the first heating component 1 and the second heating component 2 are arc-shaped structures. When the ceramic heater is in use, the first heating component 1 and the second heating component 2 are connected to form a cylinder fixed to the outside of the object being heated. The object is heated by heating the inside of the ceramic block 6. In order to reduce the heat loss of the ceramic heater, an insulation shell 3 is installed on the outside of the ceramic block 6. The inside of the insulation shell 3 is filled with glass wool insulation material, thereby reducing the heat loss of the ceramic block 6 during use, making the heating efficiency of the ceramic block 6 higher and the use effect better. The stainless steel shell on the outside of the insulation shell 3 provides an installation position for the circuit connection component 8. The insulation shell 3 also plays a protective role. The top and bottom of the insulation shell 3 protrude from the top and bottom of the ceramic block 6, and a top protective pad 4 and a bottom protective pad 5 are installed, so that the inner ceramic block 6 will not be damaged by bumps, thus improving the safety of the ceramic heater. After the heating wire 7 is energized, it converts electrical energy into heat energy, increasing the heat of the ceramic block 6 to heat the object being heated.

[0019] Please see Figure 1 and Figure 4 A ceramic heater with good heat preservation effect; The device includes a circuit connection assembly 8 and a protective sleeve 12. The circuit connection assembly 8 is installed on the front of the heat insulation shell 3. The circuit connection assembly 8 includes a mounting base 11, a protective post 9, and a screw conductor 10. The mounting base 11 is installed on the front of the heat insulation shell 3, the protective post 9 is installed on the front of the mounting base 11, and the screw conductor 10 is installed through one end of the protective post 9 and is electrically connected to the heating wire 7. The protective sleeve 12 is slidably installed on the outside of the protective post 9. A connecting ring 13 is installed on the outside of one end of the protective sleeve 12. Compression springs 14 are symmetrically installed on the back of the connecting ring 13, and one end of the compression springs 14 is connected to the mounting base 11. The screw conductor 10 in the circuit connection assembly 8 is fixed by the mounting base 11 and the protective post 9. The screw conductor 10 is connected to the external circuit, enabling the ceramic heater to be powered on. To protect the circuit connection of the screw conductor 10, the protective sleeve 12 is slidably installed on the outside of the protective post 9 and connected to the mounting base 11 by the connecting ring 13 and the compression spring 14. The protective sleeve 12 elastically supports the outside of the screw conductor 10, protecting it from impact after the screw conductor 10 is connected to the external circuit connector, which could cause the circuit connection to bend and be damaged. When the screw conductor 10 is connected to the external circuit connector, pressure can be applied to the protective sleeve 12, compressing the compression spring 14 and moving the protective sleeve 12 out of the outside of the screw conductor 10, so that the screw conductor 10 can be normally connected to the external circuit without being affected by the protective sleeve 12.

[0020] Working principle: First, the ceramic heater is installed on the outside of the object to be heated. It is connected to the external circuit through the circuit connection component 8. The elastically installed protective sleeve 12 will protect the screw conductor 10 from the outside. After the heating wire 7 is energized, the electrical energy is converted into heat energy. The heating ceramic block 6 is used to heat the object. The heat insulation shell 3 located on the outside of the heating ceramic block 6 plays a role in heat preservation and protection, reducing the risk of damage to the heating ceramic block 6 from external impacts, and also reducing the loss of heat from the heating ceramic block 6.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
