EAR THERMOMETER AND HEATING CONTROL METHOD FOR THE EAR THERMOMETER

摘要

An ear thermometer and a heating control method for the ear thermometer. The ear thermometer comprises: an ear thermometer body (1), a PCBA main control board (2), an ear thermometer sensing probe (3), and an infrared sensor (4). The PCBA main control board (2) is provided within the ear thermometer body (1). A temperature sensing component (8) is fixed at the top part of the ear thermometer body (1). The temperature sensing component (8) comprises the ear thermometer sensing probe (3) and the infrared sensor (4). The ear thermometer sensing probe (3) is an insertion part adapted to the shape of the human ear canal. The infrared sensor (4) is provided within the ear thermometer sensing probe (3) and configured to collect infrared radiant energy. The temperature sensing component (8) also comprises a constant-temperature heating module (5), is provided within the ear thermometer sensing probe (3), and is electrically connected to the PCBA main control board (2). The PCBA main control board (2) controls the constant-temperature heating module (5) to heat the ear thermometer sensing component (8) at a constant temperature.
