Description

TECHNICAL FIELD

[0001] The present application relates to the ear thermometer technical field, especially relates to an ear thermometer with low thermal conductivity probe. BACKGROUND

[0002] From the clinical point of view, the eardrum (tympanic membrane) is in the core of the body, and the body temperature control center located in the hypothalamus is also supplied by the carotid artery, and can be synchronized to the core temperature faster during fever, and has more monitoring value than the body surface temperature such as the armpit. Therefore, measuring the eardrum temperature by the ear thermometer can more accurately understand the body temperature of the human body.

[0003] In the related art, the ear thermometer is a non-contact remote measurement type (remote measurement distance is about one centimeter) temperature measuring instrument, which determines the body temperature by detecting the infrared spectrum emitted by the eardrum (equivalent to the hypothalamus). According to the blackbody radiation theory, the infrared spectrum generated by objects of different temperatures is also different, so that the eardrum temperature can be measured by using a precise temperature difference infrared sensor.

[0004] However, when the air temperature is relatively low, the ear canal cooling effect commonly exists in the ear thermometer in the related art. Specifically, the temperature measuring probe of the traditional ear thermometer is relatively cold because of the low ambient temperature, and when inserted into the ear canal, the probe will absorb more heat from the ear canal, resulting in a too large temperature drop in the ear canal, which causes the ear temperature measurement result to be low. SUMMARY

[0005] In view of the above technical problems and defects, the purpose of the present application is to provide an ear thermometer with a low thermal conductivity probe, which can effectively reduce the ear canal cooling effect through the first flexible layer with a low thermal conductivity, improve the ear temperature measurement accuracy and increase the user comfort.

Thus, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0036] It should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected", etc. in the embodiments of the present application should be understood in a broad sense. For example, "connected" can be fixedly connected, or detachably connected, or integrally connected; can be mechanically connected, or electrically connected; can be directly connected, or indirectly connected through an intermediate medium, can be the communication connection between two elements, or can be wired communication connection, or wireless communication connection. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The embodiments of the present application will be specifically described below.

[0037] In a low temperature environment, the measurement process of the traditional ear thermometer often faces the challenge of ear canal cooling effect. When users use these ear thermometers, they often find that due to the low ambient temperature, the probe will quickly lose heat before contacting the skin and become quite cold. When the cold probe is inserted into the ear canal for ear temperature measurement, the lower temperature of the probe will quickly absorb the heat in the ear canal, causing a temporary drop in local temperature. This cooling effect causes the temperature reading captured by the ear thermometer to be lower than the actual eardrum temperature, resulting in measurement error. Since the drop in temperature in the ear canal can be quite significant, the resulting measurement result can not accurately reflect the true body temperature status of the individual.

[0038] In addition, the cold probe contacting the sensitive ear canal skin can also cause discomfort to the user, affecting the measurement experience. Therefore, the ear canal cooling effect not only affects the accuracy of ear temperature measurement, but also reduces the comfort of the user when measuring body temperature.

[0039] Therefore, the ear thermometer with a low thermal conductivity probe provided by the embodiments of the present application has the advantages that Figure 1 and 2 as shown, the ear thermometer includes an ear thermometer body 1, a temperature measuring probe 2, and a first flexible layer 3; the temperature measuring probe 2 is arranged at the front end of the ear thermometer body 1 and is used to detect the temperature of the eardrum; the first flexible layer 3 covers at least part of the outer surface of the temperature measuring probe 2, and the thermal conductivity of the first flexible layer 3 is lower than a set thermal conductivity threshold; when the temperature measuring probe 2 detects the temperature inside the ear canal, the first flexible layer 3 is in contact with the ear canal.

[0040] The ear thermometer of the embodiments adopts a low thermal conductivity probe technology, which significantly improves the accuracy of body temperature measurement and the user experience. The temperature measuring probe 2 has a temperature measuring sensor that can accurately capture the temperature of the eardrum, and the first flexible layer 3 covers the outer surface of the temperature measuring probe 2. The thermal conductivity of the first flexible layer 3 is lower than the thermal conductivity threshold, and the thermal conductivity is relatively low, which can effectively slow down the heat transfer when the temperature measuring probe 2 contacts the ear canal, reducing the situation that the heat of the ear canal is absorbed by the temperature measuring probe 2. This design greatly reduces the ear temperature measurement error caused by the cooling effect of the ear canal, ensuring the accuracy and reliability of the temperature measurement of the ear thermometer.

[0041] In addition, the soft texture of the first flexible layer 3 provides a more comfortable skin contact feeling, reduces the discomfort that may be caused by hard materials, and is particularly suitable for use by infants and people with sensitive ear canals. The preheating probe design of the ear thermometer further reduces the influence of environmental temperature on the measurement results, improving the measurement accuracy in low temperature conditions. In terms of hygiene, the first flexible layer 3 is also easy to clean, greatly reducing the risk of cross infection and protecting the health of the user.

[0042] In some embodiments, the thermal conductivity threshold is between 0.1 W / m·K and 0.3 W / m·K, so that the thermal conductivity of the first flexible layer 3 can be kept at a relatively low and reasonable level. In this way, the thermal conductivity can be reduced to ensure the accuracy of the ear temperature detection results, and the ear canal skin will not feel too cold.

[0043] In actual applications, a flexible material with a thermal conductivity meeting the above conditions can be selected as the first flexible layer 3.

[0044] In some embodiments, the material of the first flexible layer 3 includes ethylene-vinyl acetate copolymer.

[0045] ethylene-vinyl acetate copolymer), whose molecular formula is (C2H4) x .(C4H6O2) y This design of the present embodiment is based on the low thermal conductivity and high softness of EVA. The EVA material plays a key role in reducing heat conduction when the probe contacts the ear canal, effectively alleviating the cooling effect of the ear canal caused by the cold probe, thereby improving the accuracy of the measurement. In addition, the soft texture of EVA provides a more comfortable experience for users, especially for users who need frequent measurements or are sensitive to the ear canal. The gentle touch of this material reduces possible discomfort. By using EVA material, the ear thermometer not only ensures measurement accuracy but also improves user comfort when touching, achieving dual optimization of functionality and user experience.

[0046] In some embodiments, the ear thermometer further comprises a second flexible layer 4, the first flexible layer 3 covering at least the rear end portion of the temperature measuring probe 2, the second flexible layer 4 covering at least the front end portion of the temperature measuring probe 2, the wear resistance of the second flexible layer 4 being superior to that of the first flexible layer 3.

[0047] This design of the present embodiment significantly improves the durability and functionality of the probe. The wear resistance of the second flexible layer 4 is superior to that of the first flexible layer 3, which means that the probe can better resist friction and wear during use, prolonging the service life of the ear thermometer. In addition, the front end portion is the area where the probe directly contacts the ear canal, and the second flexible layer 4 with stronger wear resistance can provide more stable measurement results and maintain the long-term performance of the probe. The design of the upper and lower flexible layers not only enhances the physical properties of the probe but also may achieve better thermal and tactile effects through the combination of different materials, further improving the overall performance of the ear thermometer.

[0048] In some embodiments, the material of the second flexible layer 4 includes thermoplastic polyurethane.

[0049] Thermoplastic polyurethane is commonly known as TPU, and TPU material has excellent wear resistance, strength and flexibility. The application of TPU material in the second flexible layer 4 provides additional protection for the probe, ensuring that the front end portion of the probe maintains good condition during long-term use and reduces wear caused by friction. In addition, the high elasticity of TPU allows the probe to quickly recover its shape even after repeated use, maintaining measurement accuracy. By using TPU in the critical area, the probe of the ear thermometer can better adapt to the shape and size of different users' ear canals while ensuring the stability and reliability of the measurement, providing a more durable and consistent measurement experience for users.

[0050] In some embodiments, the first flexible layer 3 covers part of the area of the second flexible layer 4.

[0051] Specifically, in the area where the first flexible layer is connected to the second flexible layer, the first flexible layer covers part of the second flexible layer. This design can provide additional softness and protection in the critical area of the probe. The first flexible layer, usually made of soft material such as EVA, covers part of the area of the second flexible layer, which can reduce friction when the probe contacts the ear canal and improve user comfort. Due to its low thermal conductivity, the first flexible layer, which partially covers the second flexible layer, can act as a thermal insulation layer, reducing the absorption of ear canal heat by the probe during measurement due to excessively low external temperature, thereby avoiding local cooling of the ear canal and measurement errors.

[0052] This design not only enhances the durability of the probe, but also has a positive impact on the thermal performance of the probe. Through partial coverage, the first flexible layer 3 can provide additional thermal insulation on the basis of the wear-resistant properties of the second flexible layer 4, further reducing heat conduction when the probe contacts the ear canal. This composite structure design allows the ear thermometer to maintain high-precision measurement while optimizing user experience through the complementary properties of the materials.

[0053] In some embodiments, as shown in Figure 3 The ear thermometer further comprises a connected main control module 101 and a storage module 102, the temperature probe 2 is connected to the main control module 101, and the main control module 101 is used to store the temperature data detected by the temperature probe 2 to the storage module 102.

[0054] This embodiment adds intelligent data management functions. By integrating the main control module 101 and the storage module 102, the ear thermometer can effectively store and manage the temperature data detected by the temperature probe 2. This design significantly improves the convenience and reliability of data recording, allowing users to easily review and analyze body temperature trends. In addition, intelligent data management functions can also be synchronized with modern smart devices, providing users with more comprehensive health monitoring solutions. Through this technology, the ear thermometer is no longer just a one-time measurement tool, but a key component in the health management ecosystem, providing users with continuous, long-term health monitoring capabilities

[0055] In some embodiments, the ear thermometer further comprises a connected camera module 103 and an ear recognition module 104, the camera module 103 is arranged at the front end of the ear thermometer body 1, and the ear recognition module 104 is arranged inside the ear thermometer body 1, the camera module 103 is used to take an ear image of the target to be measured, the ear recognition module 104 is used to identify the identity of the target to be measured according to the ear image, and the main control module 101 is connected to the ear recognition module 104.

[0056] By introducing the camera module 103 and the ear recognition module 104, the ear thermometer is equipped with advanced personalized recognition functions. The camera module 103 can take images of the ear of the target to be measured, and the ear recognition module 104 uses these images to identify the identity of the user. This design not only improves the accuracy of the measurement, because it can ensure that the data record corresponds to the correct user identity, but also increases the security and privacy of the ear thermometer. Through personalized recognition, users can more confidently manage their health data, and medical institutions or families can more effectively track and analyze individual body temperature changes. In addition, the application of this technology can also be extended to other fields such as home security, health monitoring, etc., making the ear thermometer a multifunctional smart device.

[0057] Specifically, when the user takes an ear temperature measurement, the camera module 103 located at the front end of the ear thermometer body 1 has a shooting angle that is just aimed at the ear of the target to be measured, that is, the ear image of the target to be measured can be taken, and then the camera module 103 sends the ear image to the ear recognition module 104 for recognition processing. After the ear recognition module 104 identifies the identity information of the target to be measured, the main control module 101 associates the measured body temperature data with the identity of the user according to the exact identity information provided by the ear recognition module 104. In this process, the main control module 101 first receives real-time body temperature data from the temperature probe 2, which is collected by a high-precision sensor and transmitted to the main control module 101 for processing. Subsequently, the main control module 101 pairs these data with the user's identity information, ensuring that each body temperature record can be accurately corresponded to a specific individual.

[0058] After the association operation is completed, the main control module 101 will transmit these structured data to the storage module 102. The storage module 102, as the data center of the ear thermometer, is responsible for safely saving all users' body temperature records. These data not only include real-time temperature readings, but also contain user identity, providing a reliable basis for future data analysis, health monitoring, and medical records. In addition, this associated storage method also helps to quickly retrieve the temperature history of a specific user when needed, facilitating long-term health trend analysis or providing a reference for medical professionals when necessary.

[0059] Through this intelligent data association and storage mechanism, the ear thermometer not only improves the accuracy and convenience of body temperature measurement, but also provides a health management solution for users. It enables users to better understand their body temperature changes, while also providing valuable health data resources for families, medical institutions, or researchers. The application of this technology undoubtedly enhances the practicality and personalized service capabilities of the ear thermometer, making it an innovative and effective tool in the field of health monitoring.

[0060] In some embodiments, the ear recognition module 104 integrates an ear recognition model. The ear recognition module 104 analyzes the ear image through the ear recognition model to identify the identity information of the target being measured.

[0061] The ear recognition model is trained through deep learning techniques to recognize and distinguish the ear features of different individuals. Through a large number of ear image data of different shapes, sizes, and features, the model learns how to accurately identify and distinguish the unique ear contours and feature points of each user. This advanced biometric technology not only improves the accuracy of user authentication, but also enhances the security and reliability of the system.

[0062] The training process of the ear recognition model is as follows: first, a large number of ear images of different individuals are collected, which should cover a variety of features such as different ear types, sizes, skin colors, and possible occlusion conditions, to ensure that the model can learn enough features to distinguish different ears. Subsequently, these images are labeled to determine the individual identity information corresponding to each image.

[0063] Next, the deep learning algorithm is trained using these labeled data sets. During the training process, the algorithm learns to recognize key features in the ear images and classifies the images into the correct individual based on these features. This process may include using deep learning architectures such as convolutional neural networks (CNN), calculating prediction results through forward propagation, and adjusting weights and biases in the network through backpropagation to minimize prediction errors.

[0064] To improve the generalization ability of the model, data augmentation techniques such as rotation, scaling, cropping, or adding noise are often used to simulate different shooting angles and conditions. In addition, to prevent overfitting, regularization techniques, Dropout, or the introduction of pre-trained models as feature extractors may also be used.

[0065] After training, the model's performance needs to be evaluated on an independent validation set to ensure its accuracy and robustness. This process may require multiple iterations, each iteration including adjustments to the model structure or training parameters until the model reaches a satisfactory performance level. Finally, the trained ear recognition model can accurately identify and distinguish the ear features of different individuals, providing reliable user identity recognition for the ear thermometer.

[0066] In some embodiments, the ear thermometer also includes an acceleration sensor 105 disposed on the ear thermometer body 1 and connected to the main control module 101, which is connected to the camera module 103.

[0067] In this embodiment, when the user picks up the ear thermometer for ear temperature measurement, the acceleration sensor 105 will collect signals of acceleration changes, and the main control module 101 will control the camera module 103 to start shooting the ear image according to the signals.

[0068] Specifically, the introduction of the acceleration sensor 105 enables the ear thermometer to intelligently recognize the user's actions. When the user picks up or moves the ear thermometer to prepare for measurement, the acceleration sensor 105 instantly captures signals of acceleration changes. These signals are transmitted to the main control module 101, triggering a series of automated responses, such as activating the camera module 103 to prepare to capture the ear image, thereby ensuring that the device is in a standby state at the moment the user starts the measurement.

[0069] This intelligent sensing design significantly reduces the complexity of user operations, making the measurement process more smooth and natural. The user does not need to manually start the camera module 103, and the ear thermometer can automatically recognize the measurement action and respond. This automated process not only improves efficiency but also reduces the risk of incorrect measurement due to improper operation.

[0070] In addition, the use of the acceleration sensor 105 also brings energy-saving effects. Since the camera module 103 is only activated when needed, it avoids unnecessary operation, thereby prolonging the battery life of the device. At the same time, the main control module 101 activates the camera module 103 to start shooting only when there is no significant change in the detection signal, i.e., when the ear thermometer is in a stable state. This ensures the clarity of the ear image, and this intelligent control mechanism helps to improve the stability and accuracy of the measurement.

[0071] The integration of the acceleration sensor 105 not only enhances the intelligent operation experience of the ear thermometer, but also enhances the accuracy of the measurement and the energy-saving performance of the device, providing a high-efficiency, accurate, and easy-to-use body temperature measurement solution for users.

[0072] In some embodiments, the ear thermometer further comprises an ambient brightness detection module 106 and an illumination module 107. The illumination module 107 is arranged at the front end of the ear thermometer body 1, and the ambient brightness detection module 106 is arranged on the ear thermometer body 1. The main control module 101 is connected to the ambient brightness detection module 106 and the illumination module 107, respectively.

[0073] Specifically, when the user picks up the ear thermometer for ear temperature measurement, the acceleration sensor 105 will collect signals of acceleration changes, and the main control module 101 will control the ambient brightness detection module 106 to detect the ambient brightness according to the signals of acceleration changes. If the ambient brightness is lower than the set brightness threshold, the main control module 101 will send a lighting instruction to the illumination module 107 to make the illumination module 107 emit light.

[0074] The design of the ear thermometer in this embodiment introduces an ambient brightness detection module 106 and an illumination module 107, which are intelligently linked with the main control module 101, greatly improving the adaptability and user experience of the ear thermometer under different lighting conditions. When the user picks up the ear thermometer to prepare for ear temperature measurement, the built-in acceleration sensor 105 can sensitively capture the acceleration change signals generated by the user's actions. These signals are then transmitted to the main control module 101, triggering the main control module 101 to activate the ambient brightness detection module 106 to monitor the current ambient light intensity in real time.

[0075] The role of the ambient brightness detection module 106 is to assess whether the ambient light is sufficient to provide a clear ear image for the camera module 103. If it is detected that the ambient brightness is below the preset brightness threshold, indicating that the current ambient light is insufficient and may affect the clarity of the ear image and the subsequent accuracy of ear recognition, the main control module 101 will immediately send a lighting instruction to the illumination module 107. The illumination module 107 is located at the front end of the ear thermometer main body 1 and can provide auxiliary light sources when needed, making it easy for the user to insert the temperature measurement probe 2 into the ear canal, while ensuring that the camera module 103 can capture high-quality ear images under any lighting conditions.

[0076] This intelligent lighting control function not only improves the accuracy of ear recognition, but also ensures the reliability of temperature measurement, whether the user is in a room with dim indoor light or in an outdoor environment with direct sunlight, consistent measurement experience can be achieved. In addition, this automated brightness detection and illumination activation process does not require manual operation by the user, simplifying the use process and improving the convenience of operation.

[0077] The addition of the illumination module 107 also has energy-saving effects. It is only activated when the ambient brightness is below the set threshold, avoiding unnecessary energy waste and improving the energy efficiency of the device. At the same time, this intelligent control mechanism also helps to improve the stability and accuracy of measurement, because only when the ear thermometer is in a stable state and the ambient light is sufficient, the camera module 103 will be activated, ensuring the clarity of the ear image and the accuracy of subsequent ear recognition.

[0078] This design of the present embodiment not only ensures measurement accuracy, but also provides users with a more convenient and comfortable user experience. This design not only improves the intelligence level of the device, but also enhances its adaptability under various lighting conditions, making the ear thermometer a highly efficient, accurate and easy-to-use temperature measurement tool.

[0079] In some embodiments, the ear thermometer further comprises a voice module 108, which is arranged on the ear thermometer main body 1, and the voice module 108 is connected with the main control module 101.

[0080] The ear thermometer is equipped with a voice module 108, which greatly improves the ease of use and accessibility of the ear thermometer. The voice module 108 can provide voice prompts or report measurement results, so that visually impaired users or in the case of hands-free operation can also use the ear thermometer conveniently. Through voice feedback, users can more intuitively understand the measurement process and results without looking at the display screen or relying on other visual cues. In addition, the voice module 108 can also provide customized voice services such as multi-language support, voice interaction, etc. according to the user's personalized needs, making the ear thermometer a more personalized and intelligent health monitoring device.

[0081] In some embodiments, the ear thermometer also includes a wireless network module 109, through which the host module 101 can interact with the cloud server. The temperature measurement data can be synchronized to the cloud server, and the user can obtain the temperature measurement data from the server through a communication device or a network device.

[0082] This embodiment enables the ear thermometer to have the ability of remote data synchronization by integrating the wireless network module 109. Through the wireless network module 109, the host module 101 can interact with the cloud server in real time, automatically synchronizing the body temperature data obtained from each measurement to the cloud. Users can access these temperature measurement records stored on the cloud server at any time and anywhere through smartphones, tablets or other network devices. This design not only provides users with a convenient data management method, but also allows medical professionals or family members to remotely monitor and analyze body temperature changes, thereby providing strong support for health management and disease prevention.
