Description

Technical Field

[0001] This invention relates to the field of forehead thermometer technology, and in particular to a forehead thermometer and temperature measurement method with user identification and calibration functions. Background Technology

[0002] Currently, the most common temperature measuring devices on the market are infrared forehead thermometers and infrared cochlear thermometers. However, most forehead thermometers measure body temperature based on an estimated value, meaning the measured forehead temperature does not represent the actual body temperature, resulting in low measurement accuracy. Most cochlear thermometers require inserting the probe deep into the ear canal, which is inconvenient and can cause discomfort to the user. Because of the differences between the measured forehead temperature and the actual body temperature among individuals, there is a significant error when calculating the body temperature of different individuals using forehead temperature measurements. Therefore, there is an urgent need in the market for a temperature measuring device that can provide accurate forehead temperature measurements. Summary of the Invention

[0003] The purpose of this invention is to provide a forehead thermometer and temperature measurement method with user identification and calibration functions, which can solve the problem that forehead temperature cannot accurately measure body temperature in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses a forehead thermometer with user identification and calibration functions, comprising a temperature sensor, a calibrator, a processor, a display device, and a control device. The temperature sensor is electrically connected to the calibrator and is used to measure the actual temperature values ​​of the ear and forehead. The processor is electrically connected to both the calibrator and the temperature sensor. The control device includes a first switch, a second switch, and an information input device. The first and second switches are used to switch between ear temperature measurement mode and forehead temperature measurement mode. When the first switch is turned on, the ear temperature measurement mode is entered, and the temperature sensor measures and records the ear temperature value on the calibrator. After a preset time, the first switch is turned off and the second switch is turned on, entering the forehead temperature measurement mode, where the temperature sensor measures and records the forehead temperature value on the calibrator. The calibrator obtains a forehead temperature correction value based on the difference between the ear temperature and the forehead temperature. When the forehead temperature is measured again after a specific period of time, it enters the calibrated temperature measurement mode. The temperature sensor measures the actual forehead temperature value. The processor automatically completes the forehead temperature measurement calibration and generates a body temperature value using the actual forehead temperature value and the forehead temperature correction value. This body temperature value is used to measure the forehead temperature of the user being calibrated. After calibration, the forehead thermometer remains in the currently calibrated temperature measurement mode to measure the accurate forehead temperature after calibration. The display device displays the body temperature value. The information input device is electrically connected to the processor. The processor records the user's identity information through the information input device and associates the forehead temperature correction value with the user's identity information so that the user can obtain an accurate body temperature value simply by measuring the forehead temperature during normal use.

[0005] By combining a temperature sensor, calibrator, processor, and display device, the actual ear temperature measurement value is correlated and equivalent to the actual forehead temperature measurement value, making the measured forehead temperature equivalent to the actual ear temperature measurement. The display can then show the user's ear temperature measurement, thereby achieving accurate forehead temperature measurement. After calibration, the user can directly perform forehead temperature measurement to obtain an accurate body temperature value in the future.

[0006] Furthermore, when the first switch is turned on, the device enters the ear temperature measurement mode, where the temperature sensor measures the temperature, and the calibrator records the measured value as the ear temperature. When the first switch is turned off, the device enters the forehead temperature measurement mode, where the temperature sensor measures the temperature again, and the calibrator records the measured value as the forehead temperature. The calibrator obtains the forehead temperature correction value based on the difference between the ear temperature and the forehead temperature, and then transmits the correction value to the processor for calibration. When the forehead temperature is measured again after a specific time, the processor can automatically complete the forehead temperature calibration. Using the first switch to control the forehead thermometer to enter the ear temperature measurement mode makes the command clear and easy to operate.

[0007] Furthermore, the forehead thermometer includes a thermometer body and a forehead thermometer cover. The thermometer body includes a temperature probe, with a temperature sensor located at the end of the probe. A first switch is mounted on the thermometer body. The forehead thermometer cover has a protrusion. When the forehead thermometer cover is engaged with the thermometer body, the protrusion presses the first switch, putting it in a closed state. When the forehead thermometer cover is separated from the thermometer body, the protrusion moves away from the first switch, putting it in an open state. Controlling the first switch through the engagement and disengagement of the thermometer body and the forehead thermometer cover facilitates clear distinction between forehead temperature and ear temperature measurement modes during the calibration process. During subsequent normal use, since only forehead temperature measurement is required, the switch can be turned off to enter forehead temperature measurement mode without removing the forehead thermometer cover, making it convenient to use.

[0008] Furthermore, when the second switch is turned on, the forehead temperature measurement mode is entered. The temperature sensor measures the temperature, and the calibrator records the measured value as the forehead temperature value. The calibrator then obtains the forehead temperature correction value based on the difference between the ear temperature value and the forehead temperature value, and transmits the correction value to the processor to automatically complete the forehead temperature calibration. The ear temperature measurement mode can also be entered by controlling the second switch, and calibration can be performed simply by measuring the ear and forehead temperatures sequentially within a preset time. Multiple calibration methods are available, allowing users to choose the most convenient operating method, while also extending the lifespan of the forehead thermometer.

[0009] Furthermore, the preset time is no more than 30 seconds. Measuring the forehead temperature after the ear temperature is measured and the preset conditions are met allows for the acquisition of the ear and forehead temperatures of the same user within a certain time interval. This reduces the impact of differences in body temperature at different times of the day for the same user, and also reduces the influence of changes in body temperature due to environmental or physical factors on the measurement, thereby ensuring accurate and reliable calibration.

[0010] Furthermore, the temperature sensor is an infrared sensor.

[0011] This invention also provides a forehead thermometer with user identification and calibration functions, using the aforementioned forehead thermometer with user identification and calibration functions, the method comprising: S201. In ear temperature measurement mode, after the temperature sensor takes a measurement, the calibrator records the measured value as the ear temperature value. S203. In the forehead temperature measurement mode, after the temperature sensor measures again, the calibrator records the measured value as the forehead temperature value. S205, the corrector obtains a forehead temperature correction value based on the difference between the ear temperature value and the forehead temperature value; S207. When the forehead temperature is measured again after a specific time, the calibrated temperature measurement mode is entered, and the processor generates a body temperature value based on the measured forehead temperature value and the forehead temperature correction value. S209. The processor records user identity information through the information input device and associates the forehead temperature correction value with the user identity information so that the user can obtain an accurate body temperature value by simply measuring the forehead temperature during normal use.

[0012] The calibrator obtains a forehead temperature correction value based on the difference between the ear temperature value and the forehead temperature value. After correction, the temperature measurement can be closer to the true body temperature. The processor generates a body temperature value through the measured forehead temperature value and the forehead temperature correction value. In normal use mode, users only need to measure their forehead temperature to obtain an accurate body temperature measurement value. At the same time, by associating user identity information, users can use their own ear temperature to calibrate their own forehead temperature. When different users use the device, the identity information of multiple users can be recorded, thereby solving the problem of large errors in forehead temperature measurement by different users.

[0013] Furthermore, step S209 includes: setting a default startup step, or setting an APP control step, or setting a response button step, or setting a fingerprint recognition step, or setting an iris recognition step. Setting a default startup step, or setting an APP control step, or setting a response button step, or setting a fingerprint recognition step, or setting an iris recognition step allows users to accurately and conveniently record information.

[0014] Furthermore, after recording the measured value as ear temperature, the calibrator needs to meet preset conditions before recording the measured value as forehead temperature again. These preset conditions include a preset time period. This step performs forehead and ear temperature measurements within a certain time frame to avoid inaccurate measurements due to excessively long intervals between measurements. Simultaneously, meeting the preset conditions allows for switching between ear and forehead temperature measurement modes, enabling the sensor to clearly distinguish between ear and forehead temperatures, thus ensuring an accurate and reliable calibration process.

[0015] Furthermore, the method also includes: obtaining multiple sets of ear temperature and forehead temperature values; obtaining multiple forehead temperature correction values ​​from the multiple sets of ear temperature and forehead temperature values; and calculating and updating the forehead temperature correction values ​​by averaging the values. Averaging multiple sets of correction values ​​makes the correction process more accurate.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are as follows: The forehead thermometer of the present invention with user identification and calibration functions can enable users to calibrate their forehead temperature according to their personal ear temperature, thereby solving the problem of large errors in forehead temperature measurement by different users. The calibrator calculates the forehead temperature correction value through the actual ear temperature value and the actual forehead temperature value. When using it normally, users only need to measure their forehead temperature to obtain an accurate body temperature value, which can make the temperature measurement closer to the real body temperature.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have a component that is centrally located. When a component is considered to be "located" on another component, it can be directly located on the other component or may also have a component that is centrally located.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Example 1 like Figure 1 and Figure 2 As shown, the forehead thermometer 100 with user identification and calibration functions in this embodiment 1 includes a temperature sensor 20, a calibrator 30, a processor 50 and a display device 40. The temperature sensor 20 is used to measure the actual temperature value. The calibrator 30 is electrically connected to the temperature sensor 20. The processor 50 is electrically connected to the calibrator 30 and the temperature sensor 20.

[0024] The forehead thermometer 100 can be calibrated for individual forehead temperature characteristics before use. When entering ear temperature measurement mode, the temperature sensor 20 measures the ear temperature and records it in the calibrator 30. Within a preset time, it enters forehead temperature measurement mode, where the temperature sensor 20 measures the forehead temperature and records it in the calibrator 30. Specifically, the temperature sensor 20 can perform two consecutive measurements, identifying the results as ear temperature and forehead temperature respectively. The display device 40 can display the ear temperature and forehead temperature in real time, and the calibrator 30 can adjust the readings based on the ear temperature and forehead temperature. The difference is used to obtain a forehead temperature correction value, which can be displayed instantly on the display device 40. When forehead temperature is measured using the forehead thermometer 100, the processor 50 generates a body temperature value based on the measured forehead temperature value and the forehead temperature correction value. After a specific time has elapsed since calibration, when the forehead temperature is measured again, the forehead temperature measurement calibration can be automatically completed and the device can enter the calibrated temperature measurement mode to measure the forehead temperature of the user being calibrated. After calibration, the forehead thermometer remains in the currently calibrated temperature measurement mode to measure the accurate forehead temperature after calibration, and the display device 40 can display the body temperature value. Preferably, the temperature sensor 20 is an infrared sensor.

[0025] During the calibration process, the actual ear temperature measurement value and the actual forehead temperature measurement value are correlated and equivalent through the cooperation of temperature sensor 20, calibrator 30, processor 50 and display device 40. That is, the actual forehead temperature measurement value is equivalent to the actual ear temperature measurement value. The display device 40 can then display the user's ear temperature measurement value as the body temperature value. After the user performs one calibration, the accurate body temperature value can be obtained by directly measuring the forehead temperature in the future.

[0026] Furthermore, it also includes a control device 10, which includes a first switch 11. When the first switch 11 is turned on, the forehead thermometer 100 enters the ear temperature measurement mode, and the calibrator 30 records the measured value as the ear temperature value. When the first switch 11 is turned off, the temperature sensor 20 records the measured value as the forehead temperature value. The calibrator 30 obtains the forehead temperature correction value based on the difference between the ear temperature value and the forehead temperature value, and transmits the forehead temperature correction value to the processor for calibration processing. After a specific time, the forehead temperature is measured again, and the processor automatically completes this forehead temperature calibration. The forehead thermometer 100 is controlled to enter the ear temperature measurement mode via the first switch 11, and it is easy to operate.

[0027] Specifically, the forehead thermometer 100 includes a thermometer body 80 and a forehead thermometer cover 70. The thermometer body 80 includes a temperature probe 82, a temperature sensor 20 located at the end of the temperature probe 82, and a first switch 11 installed on the thermometer body 80. The forehead thermometer cover 70 has a protrusion 75. When the forehead thermometer cover 70 is fastened to the thermometer body 80, the protrusion 75 presses the first switch 11, and the first switch 11 is in the closed state. When the forehead thermometer cover 70 is separated from the thermometer body 80, the protrusion 75 moves away from the first switch 11, and the first switch 11 is in the open state.

[0028] The first switch 11 is controlled by the snapping and separating of the thermometer body 80 and the forehead temperature cover 70, which makes it easy for users to clearly distinguish between ear temperature measurement mode and forehead temperature measurement mode during the calibration process. At the same time, during normal use, since only forehead temperature needs to be measured, the switch can be turned off to enter the forehead temperature measurement mode without removing the forehead temperature cover 70, making it convenient to use.

[0029] The temperature probe 82 can be used to measure both ear temperature and forehead temperature. When preset conditions are met, the temperature probe 82 can measure ear temperature and forehead temperature sequentially. The preset conditions include meeting a certain preset time.

[0030] Preferably, the control device 10 also includes a second switch 12. When the second switch 12 is turned on, the forehead thermometer 100 enters the forehead temperature measurement mode. The temperature sensor 20 records the measured value as the forehead temperature value. The calibrator 30 obtains the forehead temperature correction value based on the difference between the ear temperature value and the forehead temperature value, and transmits the forehead temperature correction value to the processor to automatically complete the forehead temperature calibration. The second switch 12 can also be used to enter the ear temperature measurement mode, and calibration can be performed simply by measuring the ear temperature and forehead temperature sequentially within a preset time. Multiple calibration methods coexist, allowing users to choose the most convenient operating method, while also extending the service life of the forehead thermometer.

[0031] Furthermore, the control device 10 also includes an information input device 13, which is electrically connected to the processor 50. The processor 50 records the user's identity information through the information input device 13 and associates the forehead temperature correction value with the user's identity information, so that the user can obtain an accurate body temperature value simply by measuring the forehead temperature during normal use.

[0032] The second switch 12 is either a push-button response switch or a timer switch. The push-button response switch allows users to control the device as needed, while the timer switch does not require user supervision and can remind customers or automatically turn on and off when preset conditions are met.

[0033] Furthermore, the preset time is no more than 60 seconds, preferably no more than 30 seconds. Specifically, the preset time can be 3 seconds, 5 seconds, 8 seconds, 15 seconds, 27 seconds, 30 seconds, 45 seconds, 50 seconds, or 60 seconds. Measuring the forehead temperature after the ear temperature is measured, and then meeting the preset conditions, allows for the acquisition of ear and forehead temperatures for the same user within a certain time interval. This reduces the impact of differences in body temperature at different times of the day for the same user, and also reduces the influence of changes in body temperature due to environmental or physical factors, thus ensuring accurate and reliable calibration.

[0034] Example 2 like Figure 3 As shown, the forehead thermometer with user identification and calibration function in Embodiment 2 uses the aforementioned forehead thermometer with user identification and calibration function. The method includes: S201. In ear temperature measurement mode, after the temperature sensor takes a measurement, the calibrator records the measured value as the ear temperature value. S203. In forehead temperature measurement mode, after the temperature sensor measures again, the calibrator records the measured value as the forehead temperature value. S205. The corrector obtains the forehead temperature correction value based on the difference between the ear temperature value and the forehead temperature value; S207. When the forehead temperature is measured again after a specific time, the calibrated temperature measurement mode is entered, and the processor generates a body temperature value based on the measured forehead temperature value and the forehead temperature correction value. S209. The processor records the user's identity information through the information input device 13 and associates the forehead temperature correction value with the user's identity information so that the user can obtain an accurate body temperature value by simply measuring the forehead temperature during normal use.

[0035] The calibrator obtains a forehead temperature correction value based on the difference between ear temperature and forehead temperature. After correction, the temperature measurement can be closer to the true body temperature. The processor generates a body temperature value through the measured forehead temperature value and the forehead temperature correction value. In normal use mode, users only need to measure their forehead temperature to obtain an accurate body temperature value. At the same time, by associating user identity information, users can use their own ear temperature to calibrate their own forehead temperature. When different users use the device, the identity information of multiple users can be recorded, thereby solving the problem of large errors in forehead temperature measurement by different users.

[0036] Furthermore, step S209 includes: setting a default startup step, or setting an APP control step, or setting a response button step, or setting a fingerprint recognition step, or setting an iris recognition step. By setting a default startup step, or setting an APP control step, or setting a response button step, or setting a fingerprint recognition step, or setting an iris recognition step, users can accurately and conveniently register information.

[0037] Furthermore, after the calibrator records the measured value as ear temperature, it needs to meet preset conditions before recording the measured value as forehead temperature again. These preset conditions include a preset time period. This step performs forehead and ear temperature measurements within a certain time frame to avoid inaccurate measurements due to excessively long intervals between measurements. Simultaneously, meeting the preset conditions allows for switching between ear and forehead temperature measurement modes, enabling the sensor to clearly distinguish between ear and forehead temperatures, ensuring accurate and reliable calibration.

[0038] Furthermore, the preset time is no more than 60 seconds, preferably no more than 30 seconds.

[0039] Specifically, the preset time can be 3 seconds, 5 seconds, 8 seconds, 15 seconds, 27 seconds, 30 seconds, 45 seconds, 50 seconds, or 60 seconds. Measuring the forehead temperature after the ear temperature is measured, once the preset conditions are met, allows for the acquisition of the forehead and ear temperatures of the same user within a certain time interval. This reduces the impact of differences in body temperature at different times of the day for the same user, and also reduces the influence of changes in body temperature due to environmental or physical factors, thus ensuring accurate and reliable calibration.

[0040] The forehead temperature measurement method with user identification and calibration functions in this embodiment 2 further includes: obtaining multiple sets of ear temperature values ​​and forehead temperature values; obtaining multiple forehead temperature correction values ​​from the multiple sets of ear temperature values ​​and forehead temperature values; and calculating and updating the forehead temperature correction values ​​by averaging the values. Averaging multiple sets of correction values ​​makes the calibration process more accurate.

[0041] This invention relates to a forehead thermometer and temperature measurement method with user identification and calibration functions. It allows users to calibrate their forehead temperature using their own ear temperature, thus solving the problem of large errors in forehead temperature measurements between different users. Furthermore, by measuring ear temperature and meeting predetermined conditions before measuring forehead temperature, it can obtain the forehead and ear temperatures of the same user over a certain time interval, thereby reducing the impact of differences in body temperature at different times of the day for the same user, and also reducing the influence of environmental or physical factors causing changes in body temperature. The calibrator calculates a forehead temperature correction value based on the measured forehead and ear temperatures, making the temperature measurement closer to the true body temperature. The processor records the forehead temperature correction value and associates it with the user's identity, achieving a one-to-one correspondence between the user and their own body temperature, thus solving the problem of errors in forehead temperature measurements between different users. Simultaneously, it enables precise forehead temperature calibration, allowing users to obtain accurate body temperature values ​​directly after a single calibration. Furthermore, it allows for the input of different user information into a single forehead thermometer, with each user calibrating using their own forehead and ear temperatures. Each time a user enters the device, they can select the corresponding user mode to accurately measure their own body temperature, enabling multiple users to use a single forehead thermometer.

[0042] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
