Description

Technical Field

[0001] This utility model belongs to the field of ceramic heating element technology, and relates to a medical ceramic heating element. Background Technology

[0002] Medical ceramic heating elements mainly refer to heating elements made by using high-temperature alumina ceramic as the substrate, embedding or printing high-temperature resistant metal heating elements on the ceramic substrate, and then co-firing them at high temperature.

[0003] Chinese utility model patent CN210381335U discloses a ceramic heating element for medical devices, comprising a first alumina ceramic sheet, a second alumina ceramic sheet, and a tungsten paste printed circuit. The tungsten paste printed circuit connects to two electrode pads. The second alumina ceramic sheet has two electrode holes that mate with the electrode pads. The electrode pads are connected to nickel wires. A first through hole is opened in the center of the first alumina ceramic sheet, and a second through hole is opened in the center of the second alumina ceramic sheet. The two electrode holes are located on the annular side of the first alumina ceramic sheet. The tungsten paste printed circuit is arranged in a serpentine pattern covering the entire annular side of the second alumina ceramic sheet. This technical solution does not provide a protective structure for the corners of the ceramic heating element, making the corners of the ceramic heating element easily damaged, thus affecting the use of the ceramic heating element.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 3As shown, a medical ceramic heating element includes an upper ceramic layer 1, a lower ceramic layer 2, and a tungsten paste heating circuit 3 printed on opposite sides of the upper ceramic layer 1 and the lower ceramic layer 2. The upper ceramic layer 1 has two electrode holes 101 located at both ends of the tungsten paste heating circuit 3. An electrode sheet 7 and a power-conducting component connected to the electrode sheet 7 are sandwiched in the electrode holes 101. An adhesive layer 4 is provided around the upper ceramic layer 1 and the lower ceramic layer 2. An energy-absorbing layer 5 is provided on the outer side of the adhesive layer 4. A wear-resistant protective layer 6 is provided on the side of the energy-absorbing layer 5.

[0019] In use, the operator prints the tungsten paste heating circuit 3 on the opposite sides of the upper ceramic layer 1 and the lower ceramic layer 2, and clamps the electrode sheet 7 between the upper ceramic layer 1 and the lower ceramic layer 2. Then, the upper ceramic layer 1, the lower ceramic layer 2, and the electrode sheet 7 are fixedly connected together through high-temperature sintering. After high-temperature sintering, the adhesive layer 4 is bonded to the sides of the upper ceramic layer 1 and the lower ceramic layer 2 using high-temperature ceramic adhesive. The energy-absorbing layer 5 is then bonded to the side of the adhesive layer 4. Finally, the wear-resistant protective layer 6 is bonded to the side of the energy-absorbing layer 5. The wear-resistant protective layer 6 has the highest hardness and is wear-resistant and corrosion-resistant. It can directly resist mechanical impact and environmental erosion. The energy-absorbing layer 5 can further disperse external impact energy and absorb impact force. Finally, the adhesive layer 4 can improve the connection strength between the upper ceramic layer 1 and the lower ceramic layer 2, ensuring the protective effect of the wear-resistant protective layer 6 and the energy-absorbing layer 5 on the upper ceramic layer 1 and the lower ceramic layer 2. The wear-resistant protective layer 6, the adhesive layer 4 and the energy-absorbing layer 5 work together to form a multi-layer protection for the corners of the upper ceramic layer 1 and the lower ceramic layer 2, preventing the corners of the upper ceramic layer 1 and the lower ceramic layer 2 from being directly damaged by collision with the outside world, thereby improving the impact resistance of the ceramic heating element.

[0020] Furthermore, the adhesive layer 4 is made of aluminum nitride ceramic, which has extremely high thermal conductivity and good thermal stability, ensuring efficient heat transfer and a firm bond between the ceramic heating element and the protective layer.

[0021] Furthermore, the energy-absorbing layer 5 is made of carbon foam, which has low density, excellent thermal conductivity and good energy absorption characteristics, effectively dispersing impact energy while ensuring rapid heat transfer.

[0022] Furthermore, the wear-resistant protective layer 6 is made of alumina ceramic material. Alumina ceramic has good high temperature resistance and thermal conductivity, as well as excellent electrical insulation properties, which can effectively protect the edges and corners of the upper ceramic layer 1 and the lower ceramic layer 2.

[0023] Furthermore, the power-conducting component includes a nickel wire 8, one end of which is welded to the electrode plate 7, and the other end is connected to a high-temperature resistant wire 10. Both the nickel wire 8 and the high-temperature resistant wire 10 are covered with Teflon tubing 9. A terminal block 12 is provided at the end of the high-temperature resistant wire 10 away from the nickel wire 8. In use, the operator connects the terminal block 12 to an external power source and energizes the tungsten paste heating circuit 3 through the nickel wire 8 and the high-temperature resistant wire 10, thereby ensuring the reliability of the tungsten paste heating circuit 3 during heating. The Teflon tubing 9 can protect the outer surfaces of the nickel wire 8 and the high-temperature resistant wire 10, preventing damage to the nickel wire 8 and the high-temperature resistant wire 10, which would affect the heating efficiency of the tungsten paste heating circuit 3, thus ensuring the reliability of the nickel wire 8 and the high-temperature resistant wire 10 during use.

[0024] Furthermore, the connection between the nickel wire conductor 8 and the high-temperature resistant conductor 10 is covered with a rubber sleeve 11. During use, the rubber sleeve 11 can protect the connection, prevent the connection from contacting the outside world, and prevent short circuits and leakage at the connection between the nickel wire conductor 8 and the high-temperature resistant conductor.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
