[0005] Existing probes for the ear canal are usually manually inserted into the ear canal for detection, but manual hand shaking is prone to cause certain damage to the ear canal by the probe. At the same time, the existing probes for the ear canal cannot protect the temperature sensor, and the part entering the ear canal cannot be effectively replaced after use, so the practicality is low.
