[ field of technology ]

The utility model relates to the technical field of thermometers, in particular to a temperature detection device.

[ background Art ]

In daily life, besides detecting the temperature of a human body, whether the food is cooked or not can be judged by detecting the temperature of the food. For example, in the course of cooking some large pieces of food (e.g., beef, turkey), a temperature-detecting probe is inserted into the food to obtain a temperature change of the food during cooking, thereby judging whether the food is cooked or not based on the temperature change.

Probes for detecting the temperature of food include wired probes, which are typically used in non-enclosed environments, and wireless probes, which are used in enclosed environments (e.g., ovens or ovens). To facilitate storage and protection of the probes for detecting the temperature of the food, the probes are typically placed in a storage box. However, the design of the receiving box and the probes used at present is not convenient for the operation of receiving the probes and taking the probes; or the probe cannot be effectively protected. For example: placing the wireless probe in a storage box with a cover body, wherein the cover body needs to be opened when the probe is stored or taken out; or the probe is directly placed in an opening groove of the storage box, but the storage box is inclined, and the probe is easy to directly slide out of the opening to be broken. Thus, a solution is needed.
