Description

Technical Field

[0001] The utility model relates to the technical field of all-glass heating kettles, in particular to a novel all-glass heating kettle body and a heating device. Background Art

[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] At present, all-glass heating containers can avoid the problem of heavy metal residues caused by stainless steel heating, which is beneficial to drinking water health, and therefore gradually become popular among people.

[0004] In order to accurately detect the water temperature in the all-glass heating container, some merchants have installed an infrared sensor under the all-glass heating container to detect the temperature of the bottom wall of the glass to obtain the water temperature inside. However, in actual use, it was found that since the bottom of the all-glass heating container is equipped with a heating component, the heat it emits is easily transferred to the infrared sensor and interferes with the infrared sensor, thereby reducing the temperature measurement accuracy and increasing the temperature measurement error.

[0005] Of course, some businesses also set up a heat insulation cover on the outside of the infrared sensor to achieve heat insulation and cooling, but the heat insulation effect is poor. In addition, since the infrared sensor generally needs to be installed in a sealed cavity to achieve dust and water resistance, it cannot be connected to the outside air to achieve heat dissipation, which leads to a high temperature in the cavity, which greatly reduces the measurement accuracy of the infrared sensor.
