Description

[0001] The utility model relates to the technical field of kitchenware, in particular to a cover bead with stable temperature measurement. Background Art

[0002] The cover bead is a component installed on the top of the pot lid, which generally serves as a handle. Most pot lids used in daily life have a cover bead. With the improvement of people's quality of life, the styles of cover beads are increasing, and their functions are becoming more and more powerful. In order to understand the temperature inside the pot, a cover bead with a temperature sensor appeared later, which can realize the control of the temperature inside the pot, making it convenient for cooking and steaming tea and food. However, the mechanical temperature measuring device of the existing cover bead has a complex structure and is inconvenient to assemble. There is no limit column on the dial. Since the temperature of water vapor is generally above 100°C, sometimes even reaching about 160°C, it exceeds the temperature value range. At the same time, due to the excessive range of movement of the pointer, the deformation of the temperature sensor is too large, affecting the recovery accuracy. Long-term operation will affect the measurement accuracy and service life of the mechanical temperature measuring device, resulting in a poor user experience. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Utility Model Content
