Technical Field

[0001] This utility model relates to the field of ceramic heating element technology, specifically to a quartz heating cup. Background Technology

[0002] Existing technology discloses a far-infrared heated cup holder and its preparation method, application number 202010752026.7, including a cup holder and positive and negative electrodes located at the upper and lower ends of the cup holder; the cup holder is a heating structure with a coating formed by carbon nanotubes, graphite microsheets and an adhesive on its inner side; the positive and negative electrodes are connected by a wire, and a temperature control switch is provided on the wire; the temperature control switch is electrically connected to a sensor attached to the cup holder. It can be seen that the heating layer of most existing heated cups is formed by coating with far-infrared electrothermal ink, but far-infrared electrothermal ink has low conductivity, only medium to low heating power, and is not resistant to high temperatures, has poor wear resistance, and a short service life, thus failing to meet the needs of different heating conditions. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a quartz heating cup. The quartz heating cup is clean and easy to clean. Compared with the traditional radiant heating quartz tube, it has high thermal conductivity, fast heating speed, high temperature resistance, corrosion resistance, strong product reliability, long service life, and energy saving and environmental protection.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A quartz heating cup includes a substrate, a quartz base plate at one end of the substrate, a heating layer on the surface of the quartz base plate, the heating layer including a first electrode, a second electrode, and a heating circuit disposed between the first electrode and the second electrode, the second electrode surrounding the first electrode and located at the outer periphery of the quartz base plate, the first electrode being located at the center of the quartz base plate, one end of the heating circuit being connected to the first electrode, and the other end of the heating circuit being connected to the second electrode, the substrate, the quartz base plate, the heating circuit, the first electrode, and the second electrode being integrally sintered at high temperature.

[0006] Furthermore, the heating circuit is configured as a thick-film printed circuit.

[0007] Furthermore, an insulating layer is provided on the outer surface of the heating circuit.

[0008] Furthermore, the substrate is made of quartz.

[0009] Furthermore, both the substrate and the quartz base plate are made of transparent materials.

[0010] Furthermore, the heating circuit is made of at least one of silver, ruthenium, or platinum.

[0011] Furthermore, the substrate, quartz base plate, heating circuit, first electrode, and second electrode are integrally sintered in an air atmosphere at 800-900℃.

[0012] The beneficial effects of this utility model are as follows: The quartz heating cup of this utility model, by integrally sintering the substrate, quartz base plate, heating circuit, first electrode, and second electrode at high temperature, greatly improves the wear resistance of the heating layer while also possessing high heating power and strong conductivity. Compared with traditional radiant heating quartz tubes, the quartz heating cup has higher thermal conductivity, faster heating speed, higher temperature resistance, lower energy consumption, and is cleaner and safer. The heating circuit receives electrical power from the power source through the first electrode and second electrode to generate heat, and transfers the generated heat from the quartz base plate to the material located in the substrate through resistance heating. This effectively solves the problems of the cumbersome process of the existing heating cup embedding heating plates or wrapping heating wires, as well as the poor wear resistance, low heat utilization rate, and safety issues of far-infrared electrothermal ink. Thus, it greatly extends the service life of the heating cup and is energy-saving and environmentally friendly. Attached Figure Description

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0019] like Figure 1-3As shown, a quartz heating cup includes a substrate 1, one end of which is provided with a quartz base plate 2, that is, the end of the substrate 1 with the quartz base plate 2 is the closed end of the quartz heating cup. The surface of the quartz base plate 2 is provided with a heating layer, the heating layer including a first electrode 4, a second electrode 5, and a heating circuit 3 disposed between the first electrode 4 and the second electrode 5. The second electrode 5 is disposed around the first electrode 4 and located at the outer peripheral edge of the quartz base plate 2. The first electrode 4 is disposed at the center of the quartz base plate 2. One end of the heating circuit 3 is connected to the first electrode 4, and the other end of the heating circuit 3 is connected to the second electrode 5. The substrate 1, the quartz base plate 2, the heating circuit 3, the first electrode 4, and the second electrode 5 are integrally sintered at high temperature.

[0020] This utility model discloses a quartz heating cup. By integrally sintering the substrate 1, quartz base plate 2, heating circuit 3, first electrode 4, and second electrode 5 at high temperature, the wear resistance of the heating layer is greatly improved, while also possessing high heating power and strong conductivity. Compared with traditional radiant heating quartz tubes, this quartz heating cup has higher thermal conductivity, faster heating speed, high temperature resistance, low energy consumption, and is cleaner and safer. Both the first electrode 4 and the second electrode 5 are electrically connected to the heating circuit 3, allowing current to flow from one electrode to the other via the heating circuit 3. The heating circuit 3 receives electrical power from the power source through the first electrode 4 and the second electrode 5 to generate heat, and transfers the generated heat from the quartz base plate 2 to the material located in the substrate 1 through resistance heating. The first electrode 4 and the second electrode 5 have opposite polarities; for example, the first electrode 4 is positive and the second electrode 5 is negative; or the second electrode 5 is negative and the first electrode 4 is positive. It is evident that the quartz heating cup of this invention effectively solves the problems of cumbersome process of traditional heating cup embedding heating plates or wrapping heating wires, poor wear resistance of far-infrared electric heating ink, low heat utilization rate, and safety issues, thereby greatly extending the service life of the heating cup and saving energy and protecting the environment.

[0021] In this embodiment, the first electrode 4 is a circular electrode, and the second electrode 5 is a ring electrode, with any point on the second electrode 5 capable of being energized. Simultaneously, the first electrode 4 is located at the center of the quartz base plate 2, and the second electrode 5 is located at the outer periphery of the quartz base plate 2, meaning the first electrode 4 and the second electrode 5 are on the same surface. This facilitates the connection of the first electrode 4 and the second electrode 5 to an external power source, optimizing the existing heating cup's external power supply method which only has two fixed electrodes, thus enhancing its practicality.

[0022] Furthermore, the heating circuit 3 is configured as a thick-film printed circuit, which has the characteristics of good connection performance and is not easy to break, making the dense structure formed by the sintered heating circuit 3 wear-resistant and vibration-resistant.

[0023] In this embodiment, one end of the heating line 3 is led out from the outer end of the radius of the first electrode 4 and extends along the circumference of the first electrode 4. When it approaches the outer end of the radius of the first electrode 4, it moves back, that is, the heating line 3 reverses its direction at this time and extends along the circumference of the first electrode 4 in the opposite direction to the initial direction, until it connects with the second electrode 5. This setting increases the area of ​​the heating line 3, so that the heating layer heats up evenly and the heating speed is fast.

[0024] Furthermore, an insulating layer 6 is provided on the outer surface of the heating circuit 3. The insulating layer 6 serves an insulating function, preventing the heating circuit 3 from contacting other metal components and causing a short circuit, while also preventing electrical sparks from breaking down the heating circuit 3. In addition, the insulating layer 6 can be set with different colors according to usage requirements, making it widely applicable.

[0025] Furthermore, the substrate 1 is made of quartz, which improves the high-temperature resistance of the heating cup.

[0026] Furthermore, both the substrate 1 and the quartz base plate 2 are made of transparent material, which facilitates observation of the heating of the material inside the substrate 1.

[0027] Furthermore, the heating circuit 3 is made of at least one of silver, ruthenium, or platinum. Specifically, the heating circuit 3 is made of a mixture of silver, ruthenium, and platinum in a certain proportion, or the heating circuit 3 is made of one of silver, ruthenium, or platinum. It can be specifically set according to the power required by the quartz heating cup and the usage environment, and has a wide range of applications.

[0028] Furthermore, the substrate 1, quartz base plate 2, heating circuit 3, first electrode 4 and second electrode 5 are integrally sintered in an air atmosphere at 800-900℃, making the quartz heating cup clean and easy to clean. Compared with traditional radiant heating quartz tubes, it has high thermal conductivity, fast heating speed, high temperature resistance, low energy consumption, and is cleaner and safer.

[0029] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
