Temperature measuring device

A temperature measuring device, comprising:

• a device main body having a hollow probe structure;
• a signal control module disposed in the device main body;
• a temperature measurement module accommodated in the hollow probe structure of the device main body and electrically connected to the signal control module, wherein the temperature measurement module is configured for measuring a predetermined object to obtain temperature information of the predetermined object;
• and
• an information display module disposed on the device main body and electrically connected to the signal control module, wherein the information display module is configured to display the temperature information of the predetermined object obtained by the temperature measurement module;
• wherein an outer surface of the hollow probe structure of the device main body has a plurality of recessed spaces recessed therefrom and a plurality of concave areas respectively formed in the recessed spaces;
• wherein, when the hollow probe structure of the device main body directly or indirectly contacts the predetermined object, the recessed spaces of the hollow probe structure are configured to reduce a heat conduction path between the hollow probe structure and the predetermined object;
• wherein, when the hollow probe structure of the device main body directly or indirectly contacts the predetermined object, the concave areas of the hollow probe structure do not contact the predetermined object, so as to reduce a heat exchange area between the hollow probe structure and the predetermined object;
• and
• wherein each of the recessed spaces of the hollow probe structure is a transverse annular groove, and the transverse annular grooves are arranged around a same center line and separated from each other by a predetermined distance.
