Temperature measurement head structure and clinical thermometer

摘要

A temperature measurement head structure comprises a shell (14), a tube-shaped thermal conductor (13), a cap-shaped thermal conductor (12) and an infrared sensor (11). Detection holes are arranged at a front end of the shell (14) and a front end of the cap-shaped thermal conductor (12). The tube-shaped thermal conductor (13) is located inside the shell (14). A bottom surface of the infrared sensor (11) and an end portion of the tube-shaped thermal conductor (13) are closely adhered to the detection hole at the front end of the shell (14). The cap-shaped thermal conductor (12) surrounds the infrared sensor (11) and is sleeved on an external wall at the end portion of the tube-shaped thermal conductor (13). The detection hole at the front end of the cap-shaped thermal conductor (12) is located behind the detection hole at the front end of the shell (14). The temperature measurement head structure further comprises an air gap (20) formed between top and side surfaces of the infrared sensor (11) and the cap-shaped thermal conductor (12). Also provided is a clinical thermometer comprising the temperature measurement head structure. The clinical thermometer has a simple structure, and greatly improves the precision and reliability of temperature measurement.

主权项

1. A temperature measurement head, comprising: a casing, a tubular conductor, a cap-shaped conductor, an infrared sensor, and an air gap;
wherein
both the casing and the cap-shaped conductor comprise a detecting hole at a front end thereof;the tubular conductor is disposed inside the casing; a bottom surface of the infrared sensor is attached to an end part of the tubular conductor and corresponds to the detecting hole of the front end of the casing;the cap-shaped conduct surrounds the infrared sensor and is tightly fitted over an outer wall of the end part of the tubular conductor;the detecting hole of the front end of the cap-shaped conductor is disposed behind the detecting hole of the front end of the casing; andthe air gap is disposed between an outer sidewall surface and a top surface of the infrared sensor and corresponding inner sidewall surface and inner bottom surface of the cap-shaped conductor and completely separates the outer sidewall surface and the top surface of the infrared sensor from the corresponding inner sidewall surface and inner bottom surface of the cap-shaped conductor.
