[0028] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. In order to make the above purpose, features and advantages of the application more obvious and easy to understand, a lot of specific details are set forth in the following description so as to fully understand the application. But the application can be implemented in many other ways different from the description, and the person skilled in the art can make similar improvements without departing from the connotation of the application, so the application is not limited by the following disclosed specific embodiments.
[0029] Reference Figures 1-6The liner assembly comprises a non-metal liner 1 and a metal heat-conducting part 2. The bottom of the non-metal liner 1 is provided with an opening for passing through the inner cavity of the non-metal liner 1. The metal heat-conducting part 2 is fixed on the bottom opening of the non-metal liner 1, and a cavity is formed between the metal heat-conducting part 2 and the non-metal liner 1. Alternatively, the bottom of the non-metal liner 1 is a sealed end, and the metal heat-conducting part 2 is detachably installed on the inner cavity of the non-metal liner 1.
[0030] The material of the non-metal liner 1 is glass or ceramic, and the material of the metal heat-conducting part 2 is titanium or stainless steel.
[0031] A sealing ring is arranged between the metal heat-conducting part 2 and the bottom opening of the non-metal liner 1 to form a sealing fit therebetween.
[0032] In this embodiment, the bottom opening of the metal heat-conducting part 2 is provided with an annular step, and the non-metal liner 1 is fixed on the annular step by adhesion, which is equivalent to sealing the gap between the metal heat-conducting part 2 and the bottom opening of the non-metal liner 1 by glue pouring.
[0033] In this embodiment, the non-metal liner 1 and the metal heat-conducting part 2 are placed in an electromagnetic heating device, such as an induction cooker. When the electromagnetic coil disc of the induction cooker works, an alternating magnetic field is generated, so that the metal heat-conducting part 2 is in a heated state. The food and liquid in the non-metal liner 1 directly contact the metal heat-conducting part 2, so that the heat transfer is high, and the heating time can be effectively shortened.

When the metal heat-conducting part 2 is suspended on the inner bottom wall of the non-metal liner 1, the alternating magnetic field passes through the non-metal liner 1 and acts on the metal heat-conducting part 2 to form an eddy current. Due to the existence of resistance, heat is generated to convert electrical energy into heat energy.

[0044] The electromagnetic heating body 5 is provided with an avoiding opening corresponding to the temperature probe of the temperature sensor 7, a spring 8 is arranged on the outer side of the temperature sensor 7, and the temperature sensor 7 is elastically axially moved along the avoiding opening through the spring 8.
