Ear thermometer with rotary temperature measuring head

Abstract

The invention relates to the technical field of ear thermometers, in particular to an ear thermometer with a rotary temperature measuring head. The ear thermometer comprises a gun-shaped body, a handle is mounted on the lower surface of the gun-shaped body; a display screen is rotationally mounted on the upper surface of the gun-shaped body; a temperature measuring probe is rotationally mounted onthe outer surface of one side of the gun-shaped body; a limiting sheet is fixed at one end of the outer surface of the temperature measuring probe; a control key is mounted at the upper end of the front surface of the handle; a heat dissipation net is arranged on the outer surface of the other side of the gun-shaped body, an infrared temperature measurement sensor and an endoscope are installed in the temperature measurement probe, an illuminating lamp strip and a transparent piece are installed at one end of the temperature measurement probe, a rotating rod is arranged at one end of the temperature measurement probe, and a first transmission gear is welded to the outer surface of one side of the rotating rod. The ear thermometer is compact in structure, the temperature measuring head ofthe ear thermometer can rotate, the ear thermometer has the endoscopic function, a silica gel limiting piece is arranged at the contact position of the ear thermometer and the ear, and the control keyis a capacitive touch key.

Description

technical field [0001] The invention relates to the technical field of ear thermometers, in particular to an ear thermometer with a rotating temperature measuring head. Background technique [0002] The ear thermometer is a non-contact telemetry (although it may be less than one centimeter) temperature measuring instrument. It uses the infrared spectrum emitted by the tympanic membrane (equivalent to the hypothalamus) to determine body temperature. According to the black body radiation theory, different The infrared spectrum produced by objects with different temperatures is also different, using a thermopile infrared detector that can be accurate to 0.1°C, and then using a microcomputer to convert the readings and display them.

[0003] A Chinese patent discloses an ear thermometer with a rotating temperature measuring head (authorized announcement number CN108151882B), however, the ear thermometers currently on the market generally cannot rotate the temperature measuring head, resulting in the need to adjust the gun body for temperature measurement, resulting in a device It is inconvenient to use, and if the adjustment angle is large, it is inconvenient to view the detection information. Generally, there is no endoscopic function, which is not conducive to viewing the inside of the ear canal. Turning the gun without viewing the inside will cause damage to the ear canal. If there is a lot of earwax inside the ear canal It will affect the accuracy of temperature measurement. Most of the devices are in hard contact with the ear. During use, the contact with the ear will cause discomfort. The buttons of most devices are push-type. During the pressing process, the force of the hand will cause the displacement of the gun body, resulting in the detection after adjustment. bit offset, which affects the operation
