Description

TECHNICAL FIELD

[0001] The utility model relates to an ear temperature gun probe and ear temperature gun and belongs to the technical field of medical equipment. BACKGROUND

[0002] An ear temperature gun is a medical instrument specially used for measuring human body temperature. An ear temperature gun probe is an important component thereof. A conventional ear temperature gun probe does not have a preheating function. When detecting body temperature, it is affected by the ambient temperature, which easily reduces the temperature measurement accuracy. Moreover, the ear temperature gun probe is inserted into the ear from the external environment, which easily makes people feel uncomfortable and affects the experience.

[0003] A kind of infrared sensor with preheating function has been widely used in ear temperature gun. The advantage of this sensor is that it can adjust the internal temperature of ear temperature gun probe and weaken the measurement deviation caused by environmental temperature difference. However, the sensor with preheating function is greatly affected by the surrounding environment, and its temperature measurement is easily affected by the heat conduction ability of the material in contact with it. The heat conductivity coefficient of plastic material is 0.2-0.46 W / (m·K), while the heat conductivity coefficient of air is 0.023 W / (m·K), so it is necessary to minimize the contact range between the sensor and the contact piece to improve the temperature measurement accuracy of the ear temperature gun.

[0004] In the existing market, the ear temperature gun with preheating function is first fixedly connected with the support through buckling during actual production and assembly, then connected with the support through the connecting plate, and finally connected with the lower cover of the ear temperature gun through screws after the whole is assembled, and the sensor with preheating function is fixedly connected with multiple ribs in the ear temperature gun probe through interference fit. However, this design has the following problems in actual use:

[0005] 1. There is a large gap between the temperature measurement surface of the ear temperature gun probe and the body of the ear temperature gun probe. In the environment of daily use at home or in hospitals, this will cause the probe to be dirty, and small hard debris can enter the interior of the ear temperature gun through the gap, thereby affecting the function of the product. In addition, if cleaned with water or alcohol and other cleaning solvents, it will also bring the risk of water entering the internal electronic devices.

[0006] 2. When the ear temperature gun preheating probe falls to the ground or the probe is subjected to external force, since the ear temperature gun preheating probe is connected with the probe body through buckling, there will be obvious shaking between the preheating probe and the buckling, which will cause the sensor to fall into the interior of the ear temperature gun or deviate from the normal plane, easily causing inaccurate temperature measurement of the product or damage and falling of the probe, thereby causing the product to be unable to use.

[0007] 3. The contact area between the support and the temperature measurement probe is too large, which will affect the temperature measurement accuracy, and the ear temperature gun probe passes through multiple intermediate pieces to be connected to the lower cover of the ear temperature gun, which is more complex to assemble and has higher cost.
