TECHNICAL FIELD
[0001] The utility model relates to temperature measurement structure technical field, concretely relates to a heating device with temperature measurement fastening structure. BACKGROUND
[0002] Compared with the traditional stainless steel kettle, the glass kettle is widely loved by the public due to its safety, non-toxicity, high temperature resistance, strong corrosion resistance, less limescale and easy cleaning. Most of the electric kettles nowadays are equipped with temperature control technology, which can freely select the appropriate heating temperature according to the needs. In order to realize the accurate temperature control of the electric kettle, a temperature sensor is usually required to detect the water temperature in the kettle in real time. In most kettles on the market, the temperature sensor is usually installed at the bottom of the kettle, but the bottom of the kettle is usually provided with a heating disc and other heating units, and the temperature sensor will be affected by the heat of the heating unit, resulting in inaccurate temperature measurement data of the water. Some products set a thermocouple on the side wall of the kettle to avoid the heat interference of the heating unit. However, the outer side wall of the glass container is difficult to process the adaptive structure, and the thermocouple can only be pasted on the outer side wall of the glass container with glue or adhesive tape. After frequent heating, the thermocouple is easy to fall off. Some products use a heat-insulating PVE film to paste the thermocouple on the outer side wall of the glass container. During transportation, the thermocouple is also easy to fall off, resulting in abnormal temperature measurement function. The patent document with the announcement number CN214906017U records a glass kettle temperature measurement structure and a kettle, which sets the temperature sensor between the outer side walls of the shell glass liner.

The fixing seat 2 comprises an upper seat part 21 and a lower seat part 22. The bottom edge of the upper seat part 21 extends horizontally outward and then downward to form the lower seat part 22. After the fixing seat 2 is assembled with the glass liner 1, the limiting part 11 is located at the inner periphery of the lower seat part 22, and the upper seat part 21 is located above the limiting part 11. In the embodiment, the fixing seat 2 is in a split structure, comprising two parts 23 which are the same in size and have a main body in the shape of an arc. One of the parts 23 is provided with a limiting box 6. During installation, the parts 23 surround and splice and fix the outer periphery of the glass container.
[0046] In the embodiment, the bottom of the glass liner 1 is provided with a heating unit 3 and an inner liner 4. The inner liner 4 is fixedly connected to the bottom of the fixing seat 2. A cavity is formed between the inner liner 4 and the fixing seat 2. The heating unit 3 is located in the cavity. The inner liner 4 is fixedly connected to the heating unit 3 above. The heating unit 3 is fixedly connected to the glass liner 1.
