Referring to Fig. 1 to Fig. 3, Fig. 1 is a schematic diagram of the steps of a temperature calibration method of an ear thermometer with a probe cover of the present invention, Fig. 2 is a perspective view of the ear thermometer and the probe cover of the present invention, and Fig. 3 is a Front view of the invented ear thermometer. The present invention provides an ear thermometer T and a probe cover U which are matched with each other in structure. The ear thermometer T includes an ear thermometer body T1, a probe T2 and a plurality of activation elements T3. The probe T2 is set on the ear thermometer body T1, and the probe T2 can be set on the probe cover U. A plurality of activation elements T3 are provided on the ear thermometer body T1 and adjacent to the probe T2. In addition, the ear thermometer T further includes a control element (not shown). The control element is arranged inside the ear thermometer body 1, the control element is electrically connected to an electronic switch (not shown in the figure) and each activation element T3, and the control element includes a memory unit (not shown in the figure) .

The probe cover U includes a conical body U1, an annular elastic body U2 and a flange U3. The conical body U1 has a closed end U11 and an open end U12, and the closed end U11 and the open end U12 are disposed opposite to each other. When the probe cover U is set on the probe T2 of the ear thermometer T, the plurality of actuating elements T3 on the ear thermometer T can be activated by checking whether the plurality of detection positions U30 on the flange U3 of the probe cover U have holes. Pressing down/not pressing down, the plurality of activation elements T3 do not trigger the sensing signal or trigger at least one sensing signal. It should be noted that the infrared rays referred to here are mainly infrared rays emitted by the human body. The closed end U11 itself has a thickness. Since the closed end U11 is for infrared rays to penetrate, that is, where the infrared rays mainly pass, the closed end U11 has different infrared transmittances according to the thickness of the closed end U11. As for the probe cover U, the infrared transmittance of the probe cover U actually refers to the infrared transmittance of the closed end U11. Therefore, the probe cover U has different infrared transmittances according to the thickness of the closed end U11 . The annular elastic body U2 is connected to the open end U12 of the tapered body U1. The flange U3 is connected to the annular elastic body U2, and the annular elastic body U2 is located between the conical body U1 and the flange U3. It should be noted that the probe cover U provided by the embodiment of the present invention can be integrated into one type of hard earmuffs.

The present invention provides a temperature correction method for an ear thermometer T with a probe cover U, which comprises the following steps:

Step S101: Provide an ear thermometer T with a probe cover U, the ear thermometer T includes a plurality of activation elements T3 and a control element with a memory unit, and the plurality of activation elements T3 are used to sense the infrared penetration of the probe cover U. transmittance to obtain a measured transmittance value, and the memory unit stores a preset transmittance value corresponding to the infrared transmittance of the probe cover U.

In detail, in step S101, each activation element T3 includes an on state and an off state, so that a plurality of activation elements T3 are arranged and combined to form a plurality of different sensing combinations, and a plurality of different sensing combinations respectively correspond to a plurality of Different infrared transmittances, and the two infrared transmittances corresponding to any two sensing combinations in the plurality of different sensing combinations are different from each other. Similarly, the flange U3 has a plurality of detection positions U30, and each detection position U30 has a positive detection state or a negative detection state, so that the plurality of detection positions U30 are arranged and combined to form a plurality of different detections Combinations, a plurality of different detection combinations correspond to a plurality of different infrared transmittances, and any two of the plurality of different detection combinations corresponding to two infrared transmittances are different from each other.

Further, in the embodiment shown in the present invention, the activation element T3 of the ear thermometer T is a mechanical plug, and the open state of the activation element T3 is the plug-down state, and the closed state of the activation element T3 is the plug not in the state. pressed state. The positive detection state means that the flange U3 forms an opening at the detection position U30, and the negative detection state means that the flange U3 does not form an opening at the detection position U30. However, the present invention is not limited to this. In other embodiments, the positive detection state may mean that the flange U3 is formed of a light-transmitting material at the detection position U30, and the negative detection state may mean that the flange U3 is formed of an opaque material at the detection position U30 (Fig. not shown). The activation element T3 can be, for example, a photoelectric switch (photoelectric sensor), and the light transmittance/opaqueness of the plurality of detection positions U30 on the flange U3 of the probe cover U is used to block or prevent the light beam emitted by the photoelectric switch. penetration, thereby detecting the infrared penetration rate of the probe cover U. start up The ON state of the element T3 is the state where the light beam emitted by the photoelectric switch is blocked, and the OFF state of the starting element T3 is the state where the light beam emitted by the photoelectric switch is not blocked.

When the probe cover U is sleeved on the probe T2 of the ear thermometer T, if each activation element T3 is in the open state (ie, the pin is pressed down), it means that the corresponding activation element T3 is on the flange U3 of the probe cover U. The detection position U30 of is in the negative detection state (no opening is formed). Conversely, if each activation element T3 is in a closed state (ie, the latch is not pressed down), it means that the detection position U30 on the flange U3 of the probe cover U corresponding to the activation element T3 is in a positive detection state (forming a positive detection state). opening). When each activating element T3 is in an on state (ie, the latch is pressed down), each activating element T3 will send a sensing signal to the control element. Therefore, a plurality of different sensing combinations formed by the plurality of activation elements T3 (for example, one of the activation elements T3 is in an on state, and the other activation element T3 is in an off state) does not send a sensing signal or sends at least one A sensing signal is sent to the control element. The control element can identify the infrared transmittance of the probe cover U according to the received sensing signal (or not receive the sensing signal), and thereby obtain the measured transmittance value.

The memory unit in the control element stores a preset infrared transmittance value and calibration parameters. The control element corrects the sensed initial temperature according to the preset infrared transmittance value and the calibration parameter, and according to the infrared transmittance of the probe cover U sensed by the activation element T3 to obtain a corrected temperature value .

Step S102: Using the ear thermometer T to measure an object to be measured to obtain an uncorrected temperature.

Specifically, in step S102, the ear thermometer T with the probe cover U is used to measure an object to be measured, such as a human body, to obtain an initial temperature (ear temperature). However, due to the relationship between the probe cover U itself, the infrared transmittance of the probe cover U is not consistent with the preset infrared transmittance value stored in the memory unit inside the ear thermometer T. Therefore, the initial temperature obtained in this case is actually an uncorrected temperature.

Step S103: Obtain an infrared radiation energy emitted by the object to be measured according to the uncorrected temperature, the measured transmittance value, the preset transmittance value and a radiation energy measurement formula.

Step S104 : calibrating the uncalibrated temperature to a calibrated temperature according to a temperature calibration function.

Further, in steps S103 and 104, the control element inside the ear thermometer T can be, for example, a central processing unit (CPU) or a microcontroller (MCU) commonly found in electronic devices, but the present invention is not limited to this. The control element can be calculated according to a radiation energy measurement formula according to the measured uncorrected temperature, the measured transmittance value, the calibration parameter and the preset transmittance value An infrared radiation energy emitted by the object to be measured. Then, the control element calibrates the uncalibrated temperature to a calibrated temperature according to a temperature calibration function. The radiation energy measurement formula includes the following relationship: E=K×((T _objr ) ⁴ −(T _amb ) ⁴ )×t _r /t _d . Wherein, E is the infrared radiation energy emitted by the object to be measured, K is a correction coefficient, T _objr is the uncorrected temperature of the object to be measured, and the uncorrected temperature in the radiation energy measurement formula The unit of the calibration temperature is Kjeldahl, _Tamb is an ambient temperature, the unit of the ambient temperature is Kjeldahl, t _d is the preset transmittance value, and t _r is the measured transmittance value. In the present invention, the ambient temperature Tamb is preset to _296.15K .

Based on the above, the temperature correction function includes the following relationship: K×((T _objd ) ⁴ -(T _amb ) ⁴ )=(t _d /t _r )×E=(t _d /t _r )×K×( (T _objr ) ⁴ -(T _amb ) ⁴ )×t _r /t _d =K×((T _objr ) ⁴ -(T _amb ) ⁴ ). Wherein, T _objd is the corrected temperature of the object to be measured, and the unit of the corrected temperature is Kjeldahl. That is, by multiplying the radiation energy measurement formula by t _d /t _r , K×((T _objd ) ⁴ -(T _amb ) ⁴ )=K×((T _objr ) ⁴ -(T _amb ) ⁴ ), so that the uncorrected temperature T _objr of the object to be measured is corrected to the corrected temperature T _objd .
