Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology, and in particular to a body temperature measuring device. Background Technology

[0002] Patent application CN212585836U discloses an infrared thermometer comprising a first probe and a second probe. The first probe is mounted on the main unit housing, and the second probe is detachably fitted onto the first probe. When the second probe is removed, the protruding part of the first probe can be inserted into the ear canal to measure ear temperature; when the second probe is fitted onto the first probe, it can be placed close to the forehead for temperature measurement. In this technical solution, the user needs to manually fit the second probe onto the first probe when measuring forehead temperature, and then remove the second probe when measuring ear temperature. This frequent installation and removal of the second probe affects the stability of its electrical connections. Furthermore, in forehead temperature measurement mode, only the second probe measures the temperature, resulting in low measurement accuracy. Utility Model Content

[0003] This invention proposes a body temperature measuring device, which aims to solve the problem that the forehead temperature probe in a dual-probe body temperature measuring device needs to be frequently disassembled, affecting its stability, while improving the temperature measurement accuracy of the body temperature measuring device.

[0004] The body temperature measuring device provided by this utility model includes a main unit, a main unit cover, a sensing component, and a control component. The main unit is equipped with a forehead temperature probe and an ear temperature probe. The ear temperature probe has a protrusion for insertion into the ear canal. The main unit cover has a preset state connected to the main unit and covering the forehead temperature probe and the ear temperature probe, and a non-preset state detached from the main unit. The main unit cover has a first channel and a second channel for temperature measurement signals to pass through. In the preset state, the forehead temperature probe faces the first channel or partially extends into the first channel. In the preset state, the protrusion partially extends into the second channel. The sensing component is located at the mating point between the main unit and the main unit cover and is used to detect whether the main unit cover is in the preset state. The control component is electrically connected to the sensing component, the forehead temperature probe, and the ear temperature probe.

[0005] In one embodiment, the sensing component includes a magnetic element and a Hall effect sensor that generates a magnetic induction signal when the magnetic element is near it. The Hall effect sensor is located at the mating point between the main unit and the main unit cover. The magnetic element is also located at the mating point between the main unit cover and the main unit. The control component is electrically connected to the Hall effect sensor. The control component selects to simultaneously activate the forehead temperature probe and the ear temperature probe, or activate only the ear temperature probe, based on whether the Hall effect sensor generates a magnetic induction signal. Alternatively, the sensing component includes a pressure sensor triggered by the main unit cover in a preset state. The pressure sensor is located at the mating point between the main unit and the main unit cover. The control component is electrically connected to the pressure sensor. The control component selects to simultaneously activate the forehead temperature probe and the ear temperature probe, or activate only the ear temperature probe, based on whether the pressure sensor senses a pressure signal.

[0006] In one embodiment, the main unit cover includes an outer cylinder, a first cover plate, and a second cover plate. The outer cylinder has a first opening facing the main unit and a second opening away from the main unit. The first cover plate covers the first opening, and the second cover plate covers the second opening. The first cover plate and the second cover plate are each provided with a first clearance opening, which are arranged opposite to each other. A first inner cylinder is provided between the first cover plate and the second cover plate, which surrounds the first clearance opening and forms the first channel. The first cover plate and the second cover plate are each provided with a second clearance opening, which are arranged opposite to each other. A second inner cylinder is provided between the first cover plate and the second cover plate, which surrounds the second clearance opening and forms the second channel.

[0007] In one embodiment, the ear temperature probe further includes a fixing part and a first temperature sensing element. The fixing part is connected to the end of the main unit facing the main unit cover. The protruding part protrudes from the fixing part and is disposed on one side facing the main unit cover. The protruding part has an axially extending receiving cavity. The end of the protruding part away from the fixing part has an outlet communicating with the receiving cavity. The first temperature sensing element is disposed in the receiving cavity. The forehead temperature probe includes a second temperature sensing element. The second temperature sensing element is disposed on the side of the fixing part facing the main unit cover and is disposed opposite to the second channel; or the second temperature sensing element is disposed on the side of the fixing part away from the main unit cover and is disposed opposite to the second channel. The fixing part has a clearance hole disposed opposite to the second temperature sensing element.

[0008] In one embodiment, the body temperature measuring device further includes a distance sensor located at one end of the main unit facing the main unit cover. The control component is electrically connected to the distance sensor, and the control component controls the distance sensor to turn on or off based on the signal fed back by the sensing component.

[0009] In one embodiment, the main unit cover has a third channel, and the distance sensor is oriented toward or at least partially inserted into the third channel.

[0010] In one embodiment, the main unit cover includes an outer cylinder, a first cover plate, and a second cover plate. The outer cylinder has a first opening facing the main unit and a second opening away from the main unit. The first cover plate covers the first opening, and the second cover plate covers the second opening. The first cover plate and the second cover plate are each provided with a third clearance opening, and the two third clearance openings are arranged opposite to each other. A third inner cylinder is provided between the first cover plate and the second cover plate. The third inner cylinder is arranged around the third clearance opening, and the third inner cylinder surrounds to form the third channel.

[0011] In one embodiment, the body temperature measuring device further includes a distance indication device, which is located on the main unit and electrically connected to the distance sensor. The distance indication device issues an indication message based on the signal fed back by the distance sensor. The distance indication device includes an indicator light, which is electrically connected to the distance sensor and illuminates when the main unit is in a suitable position and / or deviates from a suitable position; and / or, the distance indication device includes a display screen, which is electrically connected to the distance sensor and displays the distance detected by the distance sensor.

[0012] In one embodiment, the body temperature measuring device further includes a display screen disposed on the surface of the host unit. The control component includes a control motherboard disposed inside the host unit. The control motherboard is electrically connected to the forehead temperature probe, the ear temperature probe, and the display screen. The control motherboard is used to fit the temperatures detected by the forehead temperature probe and the ear temperature probe, and display the fitted temperature on the display screen.

[0013] In one embodiment, the body temperature measuring device further includes a voice player, which is located in the host unit. The control component includes a control motherboard, which is located inside the host unit. The control motherboard is electrically connected to the forehead temperature probe, the ear temperature probe, and the voice player. The voice player is used to issue a prompt sound when the temperature measurement by the forehead temperature probe and / or the ear temperature probe is completed.

[0014] The body temperature measuring device provided by this utility model includes an ear temperature probe with an extension for insertion into the ear canal. When the main unit cover is removed, the extension of the ear temperature probe can be inserted into the ear canal for ear temperature measurement. The body temperature measuring device has an ear temperature measurement mode and a forehead temperature measurement mode. When the main unit cover is removed from the main unit, i.e., when the control component detects that the main unit cover is in a non-preset state, the body temperature measuring device is in ear temperature measurement mode. At this time, the control component turns on the ear temperature probe and turns off the forehead temperature probe, with only the ear temperature probe in working condition. When the main unit cover is placed on the main unit and covers the ear temperature probe and forehead temperature probe, i.e., when the control component detects that the main unit cover is in a preset state, the body temperature measuring device is in forehead temperature measurement mode. At this time, the control component turns on both the ear temperature probe and the forehead temperature probe simultaneously, and both probes are in working condition and are used together for forehead temperature measurement. This technical solution places both ear and forehead temperature probes on the main unit. A sensing component detects whether the main unit cover is on, automatically switching between temperature measurement modes. Since the main unit cover's primary function is to protect the probes and switch measurement modes, rather than directly participating in temperature measurement, removing and installing the cover does not affect the stability of the electrical connections of the temperature probes. Even slight wear on the cover's connections will not affect the temperature measurement function, thus ensuring the lifespan of both the first and second temperature probes. Furthermore, in this solution, removing the cover does not affect the electrical connections between the ear and forehead temperature probes and the control component. This means that in forehead temperature measurement mode, both probes can measure temperature simultaneously, and the control component can acquire data from both probes at the same time. Because dual probes can cover a wider area (e.g., the ear probe might be located at the center of the forehead, and the forehead probe around the center), errors caused by localized temperature variations at a single measurement point are reduced. Through algorithmic processing by the control component, values ​​more closely reflecting actual human body temperature are obtained, improving measurement accuracy. Attached Figure Description

[0029] Patent application CN212585836U discloses an infrared thermometer comprising a first probe and a second probe. The first probe is mounted on the main unit housing, and the second probe is detachably fitted onto the first probe. When the second probe is removed, the protruding part of the first probe can be inserted into the ear canal to measure ear temperature; when the second probe is fitted onto the first probe, it can be placed close to the forehead for temperature measurement. In this technical solution, the user needs to manually fit the second probe onto the first probe when measuring forehead temperature, and then remove the second probe when measuring ear temperature. This frequent installation and removal of the second probe affects the stability of its electrical connections. Furthermore, in forehead temperature measurement mode, only the second probe measures the temperature, resulting in low measurement accuracy.

[0030] Therefore, this utility model proposes a body temperature measuring device.

[0031] Reference Figure 1The body temperature measuring device 100 provided by this utility model includes a main unit 1, a main unit cover 2, a sensing component, and a control component. The main unit 1 is provided with a forehead temperature probe 12 and an ear temperature probe 11. The ear temperature probe 11 has a protrusion 112 for insertion into the ear canal. The main unit cover 2 has a preset state connected to the main unit 1 and covering the forehead temperature probe 12 and the ear temperature probe 11, and a non-preset state detached from the main unit 1. The main unit cover 2 is provided with a first channel 30 and a second channel 31 for temperature measurement signals to pass through. In the preset state, the forehead temperature probe 12 faces the first channel 30 or at least partially extends into the first channel 30, and the protrusion 112 partially extends into the second channel 31 in the preset state. The sensing component is located at the mating point between the main unit 1 and the main unit cover 2 and is used to detect whether the main unit cover 2 is in the preset state. The control component is electrically connected to the sensing component, the forehead temperature probe 12, and the ear temperature probe 11. The control component obtains whether the main unit cover 2 is in the preset state through the sensing component, so as to select to simultaneously turn on the forehead temperature probe 12 and the ear temperature probe 11 or only turn on the ear temperature probe 11.

[0032] In the body temperature measuring device 100 provided by this utility model, the ear temperature probe 11 has an extension 112 for insertion into the ear canal. When the main unit cover 2 is removed, the extension 112 of the ear temperature probe 11 can be inserted into the ear canal for ear temperature measurement. The body temperature measuring device 100 has an ear temperature measurement mode and a forehead temperature measurement mode. When the main unit cover 2 is removed from the main unit 1, that is, when the control component detects that the main unit cover 2 is in a non-preset state, the body temperature measuring device 100 is in the ear temperature measurement mode. At this time, the control component turns on the ear temperature probe 11 and turns off the forehead temperature probe 12, and only the ear temperature probe 11 is in the working state. When the main unit cover 2 is placed on the main unit 1 and covers the ear temperature probe 11 and the forehead temperature probe 12, that is, when the control component detects that the main unit cover 2 is in a preset state, the body temperature measuring device 100 is in the forehead temperature measurement mode. At this time, the control component turns on the ear temperature probe 11 and the forehead temperature probe 12 at the same time. Both the ear temperature probe 11 and the forehead temperature probe 12 are in the working state and are used together for forehead temperature measurement. This technical solution places both the ear temperature probe 11 and the forehead temperature probe 12 on the main unit 1, and uses a sensing component to detect whether the main unit cover 2 is covering the main unit 1 to achieve automatic switching of the temperature measurement mode. Since the main function of the main unit cover 2 is to protect the probes and realize the switching of the temperature measurement mode, and does not directly participate in temperature measurement, the removal and installation of the main unit cover 2 will not affect the stability of the electrical connection of the temperature probe. Even if the connection of the main unit cover 2 is slightly worn, it will not affect the temperature measurement function of the temperature probe, thereby ensuring the service life of the first and second temperature probes. Moreover, in this technical solution, the disassembly of the main unit cover 2 will not affect the electrical connection between the ear temperature probe 11, the forehead temperature probe 12 and the control component. This means that in the forehead temperature measurement mode, the ear temperature probe 11 and the forehead temperature probe 12 can measure the temperature simultaneously, and the control component can acquire the temperature measurement data of the ear temperature probe 11 and the forehead temperature probe 12 simultaneously. Since the dual probes can cover more areas, such as the ear temperature probe 11 being located at the center of the forehead and the forehead temperature probe 12 being located around the center of the forehead, the error caused by local temperature changes at a single measurement point can be reduced. Through the algorithm processing of the control component, a value that is more consistent with the actual human body temperature can be obtained, thereby improving the temperature measurement accuracy.

[0033] The main unit cover 2 and the main unit 1 can be magnetically connected. Specifically, the main unit cover 2 can be equipped with a first magnetic adsorption component, and the main unit 1 can be equipped with a second magnetic adsorption component. The main unit cover 2 and the main unit 1 are attracted and attached by the first and second magnetic adsorption components. The magnetic connection has an automatic alignment feature. When the main unit cover 2 is close to the main unit 1, the magnetic force will naturally guide the connection part of the main unit cover 2 and the main unit 1 to automatically align, thereby realizing the quick installation of the main unit cover 2. In addition, the user can easily remove the main unit cover 2 from the main unit 1 with a gentle pull, and the disassembly process is equally simple and quick. Alternatively, the main unit cover 2 and the main unit 1 can be connected by a snap-fit ​​connection. Specifically, the main unit cover 2 and the main unit 1 are connected by the interlocking of the snap-fit ​​structure. The snap-fit ​​connection has high firmness and stability. This connection method can effectively prevent the main unit cover 2 from accidentally loosening or falling off due to external force during use.

[0034] In this technical solution, the sensing component may include a magnetic component and a Hall sensor element that generates a magnetic induction signal when the magnetic component is close. The Hall sensor element is located at the mating point between the main unit 1 and the main unit cover 2, and the magnetic component is located at the mating point between the main unit cover 2 and the main unit 1. The control component is electrically connected to the Hall sensor element. The control component selects to simultaneously turn on the forehead temperature probe 12 and the ear temperature probe 11 or only turn on the ear temperature probe 11 based on whether the Hall sensor element generates a magnetic induction signal.

[0035] The Hall effect sensor can be disposed on the contact surface between the main unit 1 and the main unit cover 2, and the magnetic component can be disposed on the contact surface between the main unit cover 2 and the main unit 1; alternatively, the Hall effect sensor can be disposed inside the main unit 1, near the end of the main unit cover 2, and the magnetic component can be disposed at the end of the main unit cover 2 near the main unit 1. The Hall effect sensor is a sensor based on the Hall effect, capable of outputting an electrical signal when it detects a change in magnetic field. When the main unit cover 2 is connected to the main unit 1, the magnetic component approaches the Hall effect sensor, triggering the Hall effect sensor to generate a magnetic induction signal; when the main unit cover 2 is removed, the magnetic field disappears, and the Hall effect sensor no longer generates an induction signal. The control component is electrically connected to the Hall effect sensor, and selectively turns the forehead temperature probe 12 on or off based on whether the Hall effect sensor generates a magnetic induction signal, thereby switching between ear temperature measurement mode and forehead temperature measurement mode. Specifically, when the Hall effect sensor detects a magnetic signal (i.e., when the main unit cover 2 is connected to the main unit 1), the control component switches to forehead temperature measurement mode, at which time both ear temperature probe 11 and forehead temperature probe 12 are in working condition; when the Hall effect sensor does not detect a magnetic signal (i.e., when the main unit cover 2 is removed), the control component switches to ear temperature measurement mode, at which time only ear temperature probe 11 is in working condition. This embodiment achieves automatic switching of temperature measurement modes through the cooperation of magnetic components and the Hall effect sensor. The Hall effect sensor has the characteristics of high sensitivity and fast response, and can accurately detect changes in the magnetic field, thereby ensuring the accuracy and reliability of temperature measurement mode switching.

[0036] Alternatively, the sensing component can be a pressure sensor, which can generate a pressure signal when the main unit cover 2 is in a preset state. The pressure sensor is located at the mating point between the main unit 1 and the main unit cover. The control component is electrically connected to the pressure sensor. The control component can select to simultaneously turn on the forehead temperature probe 12 and the ear temperature probe 11 or only turn on the ear temperature probe 11, depending on whether the pressure sensor senses a pressure signal.

[0037] For example, the main unit 1 has a contact surface that contacts the main unit cover 2. A pressure sensor can be located on this contact surface to detect the contact pressure between the main unit cover 2 and the main unit 1, thereby monitoring whether the main unit cover 2 is on the main unit 1. Alternatively, the main unit cover 2 can have a protruding pressing part. When the main unit cover 2 is on the main unit 1, the pressing part contacts and presses against the pressure sensor, thereby causing the pressure sensor to generate a pressure signal. The pressure sensor can output an electrical signal when it detects pressure. When the main unit cover 2 is on the main unit 1, the pressure sensor will sense the pressure and output a signal; when the main unit cover 2 is removed, the pressure disappears, and the sensor no longer outputs a signal. The control component is electrically connected to the pressure sensor and selectively turns the forehead temperature probe 12 on or off according to whether the pressure sensor senses a pressure signal, thereby realizing the switching between ear temperature measurement mode and forehead temperature measurement mode. Specifically, when the pressure sensor detects a pressure signal (i.e., when the main unit cover 2 is connected to the main unit 1), the control component switches to the forehead temperature measurement mode, at which time both the ear temperature probe 11 and the forehead temperature probe 12 are in working condition; when the pressure sensor detects a pressure signal, only the ear temperature probe 11 is in working condition. The pressure sensor features high sensitivity and fast response, enabling it to accurately detect the contact pressure between the main unit cover 2 and the main unit 1, thereby ensuring the accuracy and reliability of temperature measurement mode switching.

[0038] In practical applications, pressure sensors, Hall effect sensors, and magnetic components can coexist. In this case, the sensing components employ dual detection, making the installation status of the main unit cover 2 more accurate. Even if one of the sensing elements malfunctions or misjudges, the other sensing element can still perform detection, thus improving the overall reliability of the equipment.

[0039] In this technical solution, the ear temperature probe 11 and the forehead temperature probe 12 can be infrared temperature measuring probes, which mainly measure temperature by detecting the infrared radiation energy emitted by the surface of an object through their respective infrared sensors. In order to avoid the main unit cover 2 blocking the infrared light of the ear temperature probe 11 and the forehead temperature probe 12 when it is covered by the ear temperature probe 11 and the forehead temperature probe 12, the main unit cover 2 is provided with a first channel 30 and a second channel 31 for the temperature measurement signal to pass through. The forehead temperature probe 12 is oriented towards the first channel 30 or partially inserted into the first channel 30 in a preset state, and the protrusion 112 is partially inserted into the second channel 31 in a preset state.

[0040] For example, the main unit cover 2 may have a first window and a second window spaced apart. The first window is positioned opposite the ear temperature probe 11, and the second window is positioned opposite the forehead temperature probe 12. The coverage area of ​​the first window is the first channel 30, and the coverage area of ​​the second window is the second channel 31. The first and second windows can be perforated structures, or they can be light-transmitting plates, such as light-transmitting glass, covering the perforated structures. The first window serves as the infrared receiving point for the ear temperature probe 11, and the second window serves as the infrared receiving point for the forehead temperature probe 12, so that the temperature measurement signals from the ear temperature probe 11 and the forehead temperature probe 12 can be freely emitted.

[0041] Reference Figure 4 and Figure 5 In one embodiment of the body temperature measuring device 100, the main unit cover 2 includes an outer cylinder 21, a first cover plate 22, and a second cover plate 23. The outer cylinder 21 has a first opening facing the main unit 1 and a second opening away from the main unit 1. The first cover plate 22 covers the first opening, and the second cover plate 23 covers the second opening. The first cover plate 22 and the second cover plate 23 are each provided with a first clearance opening 24, which are arranged opposite to each other. A first inner cylinder 27 is provided between the first cover plate 22 and the second cover plate 23. The first inner cylinder 27 surrounds the first clearance openings 24, and the first inner cylinder 27 encloses to form a first channel 30. The ear temperature probe 11 faces the first channel 30 or at least partially extends into the first channel 30. In this embodiment, a first inner cylinder 27 is provided between the first cover plate 22 and the second cover plate 23 to form a first channel 30. This first channel 30 can guide the transmission path of the temperature measurement signal of the ear temperature probe 11, making it more focused on the target temperature measurement area, and can reduce interference signals from other directions, such as the temperature measurement signal from the forehead temperature probe 12. This arrangement can ensure that the ear temperature probe 11 receives mainly signals from the target temperature measurement area, thereby improving the reliability of the ear temperature probe 11's temperature measurement.

[0042] Similarly, the first cover plate 22 and the second cover plate 23 are each provided with a second clearance opening 25, which are arranged opposite to each other. A second inner cylinder 28 is provided between the first cover plate 22 and the second cover plate 23, surrounding the second clearance opening 25 and forming a second channel 31. The forehead temperature probe 12 faces the second channel 31 or at least partially extends into the second channel 31. In this embodiment, by setting the second inner cylinder 28 between the first cover plate 22 and the second cover plate 23 to form the second channel 31, the second channel 31 can guide the transmission path of the temperature measurement signal of the forehead temperature probe 12, making it more focused on the target temperature measurement area, and reducing interference signals from other directions, such as the temperature measurement signal of the ear temperature probe 11. This arrangement can ensure that the forehead temperature probe 12 receives mainly signals from the target temperature measurement area, thereby improving the reliability of the forehead temperature probe 12.

[0043] Reference Figure 6 and Figure 7 In one embodiment, the ear temperature probe 11 includes a fixing part 111, an extension part 112, and a first temperature sensing element 113. The fixing part 111 is connected to one end of the main unit 1 facing the main unit cover 2 and is fitted to the first cover plate 22. The extension part 112 protrudes from the fixing part 111 and protrudes to one side facing the main unit cover 2. The extension part 112 has an accommodating cavity extending axially. The end of the extension part 112 away from the fixing part 111 has an outlet communicating with the accommodating cavity. The outlet is connected to the first clearance opening 24 on the second cover plate 23. The first temperature sensing element 113 is disposed in the accommodating cavity.

[0044] The fixing part 111 is connected to the housing of the main unit 1 and the first cover plate 22, and the connection method can be screw connection or snap connection. The protruding part 112 protrudes from the fixing part 111 and is arranged to face the side of the main unit cover 2, for insertion into the ear canal, thereby sending the first temperature sensing element 113 inside the ear canal into the ear canal for temperature measurement. The protruding part 112 can be tapered in the axial direction for easy insertion into the ear canal.

[0045] The forehead temperature probe 12 includes a second temperature sensing element, which is disposed on the side of the fixing part 111 facing the main unit cover 2 and is disposed opposite to the second channel 31. Alternatively, the second temperature sensing element is disposed on the side of the fixing part 111 away from the main unit cover 2 and is disposed opposite to the second channel 31. The fixing part 111 has a clearance hole 1111 disposed opposite to the second temperature sensing element.

[0046] The control component includes a control motherboard located inside the host 1. The first temperature sensing element 113 and the second temperature sensing element are electrically connected to the control motherboard, thereby enabling the detected temperature value to be sent to the control motherboard for fitting calculation.

[0047] Reference Figure 6 The outer edge of the fixing part 111 may be provided with a circumferentially arranged stepped part 1112. When the main unit cover 2 is in a preset state, that is, when the main unit cover 2 is connected to the main unit 1 and covers the ear temperature probe 11 and the forehead temperature probe 12, the stepped part 1112 is in a limiting fit with the outer cylinder 21. Specifically, when the main unit cover 2 is connected to the main unit 1 and covers the ear temperature probe 11 and the forehead temperature probe 12, the bottom wall and inner wall of the outer cylinder 21 respectively contact and abut against the stepped part 1112, which can realize the limiting between the main unit cover 2 and the fixing part 111, and prevent the main unit cover 2 from loosening or shifting due to external force during use.

[0048] Furthermore, the body temperature measuring device 100 may include a display screen 5, which is located in the host 1. The control component includes a control motherboard, which is located inside the host 1. The control motherboard is electrically connected to the ear temperature probe 11, the forehead temperature probe 12 and the display screen 5. The control component is used to fit the temperature detected by the ear temperature probe 11 and the forehead temperature probe 12 and display the fitted temperature on the display screen 5.

[0049] Specifically, the display screen 5 is located on the surface of the main unit 1 for easy viewing by the user during operation. The control motherboard is electrically connected to the ear temperature probe 11, the forehead temperature probe 12, and the display screen 5. The control motherboard is responsible for receiving the temperature data detected by the ear temperature probe 11 and the forehead temperature probe 12, and performing fitting processing on the data fed back by the two probes through a built-in algorithm to obtain a value that more closely matches the actual human body temperature. The fitted temperature is then displayed on the display screen 5. The display screen 5 can be either an LCD or an OLED display screen to ensure clear and accurate display of the temperature measurement results.

[0050] Furthermore, the control component also includes a temperature unit switching button 41, which is located on the surface of the host 1. The control motherboard is electrically connected to the temperature unit switching button 41 and the display screen 5. The control motherboard receives the signal fed back by the temperature unit switching button 41 and switches the temperature and temperature unit displayed on the display screen 5.

[0051] A temperature unit switching button 41 can be located near the display screen 5, allowing users to quickly switch temperature units when viewing temperature data. The temperature unit switching button 41 allows users to freely switch between Celsius (°C) and Fahrenheit (°F). The control motherboard is electrically connected to the temperature unit switching button 41 and the display screen 5. When the user presses the temperature unit switching button 41, the control motherboard receives the signal from the button, converts the temperature unit according to the currently displayed temperature unit, and updates the temperature value and unit label on the display screen 5.

[0052] Furthermore, the body temperature measuring device 100 may include a voice player, which is located in the host 1. The control component includes a control motherboard, which is electrically connected to the ear temperature probe 11, the forehead temperature probe 12 and the voice player. The voice player is used to issue a prompt sound when the ear temperature probe 11 and / or the forehead temperature probe 12 finishes measuring the temperature.

[0053] The voice player is located inside the main unit 1 and emits prompts through a speaker. The speaker's position should ensure clear sound transmission while avoiding interference with the infrared signal from the temperature probe. The control motherboard is electrically connected to the ear temperature probe 11, the forehead temperature probe 12, and the voice player. After temperature measurement, the control motherboard triggers the voice player to emit a prompt. The prompt can be a simple "beep," a voice prompt saying "Measurement complete," or a direct announcement of the temperature value. The voice prompt function provides convenience for use in low-light environments, enhancing the device's accessibility.

[0054] The control component may also include a control button 42, which is located on the surface of the host 1. The control motherboard is electrically connected to the control button 42, the display screen 5 and / or the voice player. The control motherboard receives the signal fed back by the control button 42 and switches the working mode of the display screen 5 and / or the voice player.

[0055] The body temperature measuring device 100 has a normal mode and a night mode (do not disturb mode). In normal mode, the voice player plays a prompt tone at normal volume, and the display screen 5 displays the temperature data at normal brightness. In night mode (do not disturb mode), the voice player is muted, and the display screen 5 displays the temperature data in dim light. Control buttons 42 are located on the surface of the main unit 1, allowing users to quickly switch between different modes. The control motherboard is electrically connected to the control buttons 42, the display screen 5, and / or the voice player. The control motherboard receives signals from the control buttons 42 to switch the operating modes of the display screen 5 and / or the voice player. Through the control buttons 42, the display screen 5 and / or the voice player can switch between normal mode and night mode (do not disturb mode), thus adapting to different usage scenarios and improving the flexibility of the device.

[0056] Among them, the control button 42 and the temperature unit switching button 41 can be physical buttons or touch buttons. Physical buttons have clear tactile feedback, while touch buttons can be integrated with the display screen 5. Touch buttons have high sensitivity, and users can complete operations such as mode switching or temperature unit switching simply by lightly touching the corresponding area on the screen.

[0057] Some embodiments of the body temperature measuring device 100 also include a distance sensor 13, which is located at the end of the main unit 1 facing the main unit cover 2. The control component is electrically connected to the distance sensor 13, and controls the distance sensor 13 to turn on or off based on the signal fed back by the sensing component.

[0058] When the sensing component detects that the main unit cover 2 is on the main unit 1 (forehead temperature measurement mode), the control component controls the ear temperature probe 11, forehead temperature probe 12, and distance sensor 13 to be in working state. When the sensing component detects that the main unit cover 2 is separated from the main unit 1, the control component controls the ear temperature probe 11 to be in working state and controls the forehead temperature probe 12 and distance sensor 13 to be turned off. The distance sensor 13 is used to detect whether the ear temperature probe 11 and forehead temperature probe 12 are in a suitable temperature measurement position. Specifically, in forehead temperature measurement mode, the distance sensor 13 is used to detect whether the distance between the two probes and the forehead is too far or too close. If the distance is too far or too close, the control component can prompt the user to adjust the probe position, thereby ensuring the accuracy of the measurement results. When the sensing component detects that the main unit cover 2 is separated from the main unit 1, the control component controls the ear temperature probe 11 to be in working state, and simultaneously controls the forehead temperature probe 12 and distance sensor 13 to be turned off to save energy and avoid unnecessary energy consumption.

[0059] To prevent the distance sensor 13's ranging signal from the main unit cover 2 from being obstructed when it covers the main unit 1, the main unit cover 2 is provided with a third channel 32, with the distance sensor 13 facing the third channel 32 or at least partially extending into it. The main unit cover 2 may also have a third window, which is positioned opposite the distance sensor 13, and its coverage area is the third channel 32. The third window can be a perforated structure or a light-transmitting plate, such as translucent glass, covering the perforated structure. The third window serves as the signal transmission point for the distance sensor 13, ensuring that the ranging signal from the distance sensor 13 can be emitted freely.

[0060] Or, refer to Figure 4 and Figure 5 The first cover plate 22 and the second cover plate 23 are each provided with a third clearance opening 26, and the two third clearance openings 26 are arranged opposite to each other. A third inner cylinder 29 is provided between the first cover plate 22 and the second cover plate 23, and the third inner cylinder 29 is arranged around the third clearance opening 26, forming a third channel 32. The distance sensor 13 faces the third channel 32 or at least partially extends into the third channel 32. In this embodiment, by setting a third inner cylinder 29 between the first cover plate 22 and the second cover plate 23 to form a third channel 32, the third channel 32 can guide the transmission path of the distance measurement signal of the distance sensor 13, making it more focused on the target area, and can reduce interference signals from other directions, such as the temperature measurement signals of the ear temperature probe 11 and the forehead temperature probe 12.

[0061] Furthermore, an embodiment of the body temperature measuring device 100 may also include a distance prompting device, which is located on the host 1 and electrically connected to the distance sensor 13. The distance prompting device issues a prompting message based on the signal fed back by the distance sensor 13.

[0062] A distance indicator is mounted on the main unit 1, which can be located at the front or side of the main unit 1, so that the user can clearly see the indicator information during operation. The distance indicator is electrically connected to the distance sensor 13, and the control component controls the distance indicator to issue an indicator message based on the signal fed back by the distance sensor 13. For example, the distance indicator may include an indicator light, which is electrically connected to the distance sensor 13, and is used to illuminate when the main unit 1 is in a suitable position and / or deviates from a suitable position. The indicator light may include a red light and a green light; a green light indicates that the main unit 1 is in a suitable temperature measurement position, and a red light indicates that the main unit 1 has deviated from a suitable temperature measurement position. Alternatively, the indicator light may be a flashing light, which indicates that the position of the main unit 1 needs to be adjusted.

[0063] And / or, the distance indication device may include a display screen 5, which is electrically connected to the distance sensor 13 and is used to display the distance detected by the distance sensor 13. The display screen 5 may display specific values ​​or prompts, such as "Distance: 10cm" or "Please approach the target". In practical applications, the display screen indicating the distance and the display screen displaying the temperature may be the same display screen.

[0064] The distance sensor 13 can be an infrared distance sensor 13, an ultrasonic distance sensor 13, or a laser distance sensor 13, etc. The main unit cover 2 is provided with a third window for the distance sensor 13 to measure distance. The third window is set on the main unit cover 2 at a position corresponding to the distance sensor 13, ensuring that the distance sensor 13 can transmit and receive signals without obstruction, thereby accurately detecting the distance between the probe and the target temperature measurement area and avoiding measurement errors caused by the obstruction of the main unit cover 2.

[0065] The control method for the body temperature measuring instrument 100 is as follows:

[0066] S1: The sensor component detects whether the main unit cover 2 is in a preset state or a non-preset state. The preset state is when the main unit cover 2 is connected to the main unit 1 and covers the forehead temperature probe 11 and the ear temperature probe 12. The non-preset state is when the main unit cover 2 is detached from the main unit 1.

[0067] S2: If the main unit cover 2 is in a preset state, the forehead temperature probe 11 and the ear temperature probe 12 are turned on at the same time, and the temperature value obtained by the forehead temperature probe 11 and the temperature value obtained by the ear temperature probe 12 are fitted to obtain the output temperature value.

[0068] S3: If the main unit cover 2 is not in a preset state, turn off the forehead temperature probe 11, turn on the ear temperature probe 12, and use the temperature value obtained by the ear temperature probe 12 as the output temperature value.

[0069] The body temperature measuring device 100 includes a main unit 1, a main unit cover 2, a sensing component and a control component. The main unit 1 is equipped with a forehead temperature probe 12 and an ear temperature probe 11. The ear temperature probe 11 has an extension 112 for insertion into the ear canal. When the main unit cover 2 is removed, the extension 112 of the ear temperature probe 11 can be inserted into the ear canal to measure ear temperature. The body temperature measuring device 100 has an ear temperature measurement mode and a forehead temperature measurement mode. When the main cover 2 is removed from the main unit 1, that is, when the control component detects that the main cover 2 is in a non-preset state, the body temperature measuring device 100 is in ear temperature measurement mode. At this time, the control component turns on the ear temperature probe 11 and turns off the forehead temperature probe 12, with only the ear temperature probe 11 in working state. When the main cover 2 is placed on the main unit 1 and covers the ear temperature probe 11 and the forehead temperature probe 12, that is, when the control component detects that the main cover 2 is in a preset state, the body temperature measuring device 100 is in forehead temperature measurement mode. At this time, the control component turns on both the ear temperature probe 11 and the forehead temperature probe 12 at the same time, and both the ear temperature probe 11 and the forehead temperature probe 12 are in working state and are used together for forehead temperature measurement. This technical solution places both the ear temperature probe 11 and the forehead temperature probe 12 on the main unit 1, and uses a sensing component to detect whether the main unit cover 2 is covering the main unit 1 to achieve automatic switching of the temperature measurement mode. Since the main function of the main unit cover 2 is to protect the probes and realize the switching of the temperature measurement mode, and does not directly participate in temperature measurement, the removal and installation of the main unit cover 2 will not affect the stability of the electrical connection of the temperature probe. Even if the connection of the main unit cover 2 is slightly worn, it will not affect the temperature measurement function of the temperature probe, thereby ensuring the service life of the first and second temperature probes. Moreover, in this technical solution, the disassembly of the main unit cover 2 will not affect the electrical connection between the ear temperature probe 11, the forehead temperature probe 12 and the control component. This means that in the forehead temperature measurement mode, the ear temperature probe 11 and the forehead temperature probe 12 can measure the temperature simultaneously, and the control component can acquire the temperature measurement data of the ear temperature probe 11 and the forehead temperature probe 12 simultaneously. Since the dual probes can cover more areas, such as the ear temperature probe 11 being located at the center of the forehead and the forehead temperature probe 12 being located around the center of the forehead, the error caused by local temperature changes at a single measurement point can be reduced. Through the algorithm processing of the control component, a value that is more consistent with the actual human body temperature can be obtained, thereby improving the temperature measurement accuracy.

[0070] In some embodiments of the body temperature measuring device 100, a distance sensor 13 is provided at the end of the main unit 1 facing the main unit cover 2. The distance sensor 13 is used to detect whether the distance between itself and the forehead is within a preset distance range in the forehead temperature measurement mode, and further detect whether the distance between the two probes and the forehead is within the preset distance range. The body temperature measuring device 100 also includes a distance prompting device, which is located on the main unit 1 and electrically connected to the distance sensor 13. The distance prompting device issues a prompting message based on the signal fed back by the distance sensor 13.

[0071] If the main unit cover 2 is in a preset state, after turning on the forehead temperature probe and the ear temperature probe (S21), the following steps are also included:

[0072] S22: Detect whether the distance between the distance sensor 13 and the part to be measured is within a preset distance range;

[0073] S221: If the distance between the distance sensor 13 and the part to be measured is within a preset distance range, the temperature values ​​detected by the forehead temperature probe 11 and the ear temperature probe 12 are obtained, and the temperature value obtained by the forehead temperature probe 11 and the temperature value obtained by the ear temperature probe 12 are fitted to obtain the output temperature value.

[0074] S222: If the distance between the distance sensor 13 and the part to be measured is outside the preset distance range, the distance prompting device will issue a prompt message.

[0075] Step S3: If the main unit cover 2 is not in a preset state, the following steps are also included: controlling the distance sensor and distance indication device to turn off. Specifically, if the main unit cover 2 is not in a preset state, that is, when the main unit cover 2 is removed, the body temperature measuring device is in ear temperature measurement mode, the control component controls the ear temperature probe 11 to be in working state, and at the same time controls the forehead temperature probe 12, distance sensor 13 and distance indication device to turn off, so as to save energy and avoid unnecessary energy consumption.

[0076] When the main unit cover is in the preset state, i.e., when the main unit cover is connected to the main unit and covers the forehead temperature probe 12 and ear temperature probe 11, the body temperature measuring device is in forehead temperature measurement mode. The control component controls the forehead temperature probe 12, ear temperature probe 11, distance sensor 13, and distance indication device to be in working state. The distance sensor 13 is used to detect whether the forehead temperature probe 12 and ear temperature probe 11 are in a suitable temperature measurement position. If the distance detected by the distance sensor 13 is within the preset distance range (e.g., 3cm-5cm), it means that the current position is at a suitable temperature measurement distance. If the distance detected by the distance sensor 13 is outside the preset distance range, it means that the current temperature measurement position is too far or too close. Temperature measurement at this distance may lead to measurement error. At this time, the control component receives the signal from the distance sensor 13 and controls the distance indication device to issue an indication message. The indication message can be an audible indication, a vibration indication, or a visual indication (e.g., an indicator light flashing), thereby prompting the user to adjust the probe position.

[0077] When the user adjusts the probe position according to the prompts so that the distance detected by the distance sensor is within the preset range, the control component restores the temperature values ​​of the forehead temperature probe 12 and the ear temperature probe 11 to their initial values, and controls the forehead temperature probe 12 and the ear temperature probe 11 to remeasure the temperature, thereby re-acquiring the temperature values ​​detected by the forehead temperature probe 12 and the ear temperature probe 11 at the appropriate positions, thus ensuring the accuracy of the measurement results. When the distance between the distance sensor 13 and the part to be measured is within the preset distance range, the control component simultaneously acquires the temperature measurement data of the forehead temperature probe 12 and the ear temperature probe 11. Through the algorithm processing of the control component, the temperature value fed back by the forehead temperature probe 12 and the temperature value fed back by the ear temperature probe 11 are fitted to obtain the final temperature value, resulting in a value that is more consistent with the actual human body temperature.

[0078] If the main unit cover is in a preset state, the control method further includes the following steps:

[0079] S23: Determine whether the difference between the first temperature value currently acquired by the forehead temperature probe 12 and the second temperature value currently acquired by the ear temperature probe 11 is within a preset temperature difference value;

[0080] S231: If the difference between the first temperature value and the second temperature value is within a preset temperature difference, fit the first temperature value and the second temperature value to obtain the output temperature value;

[0081] S232: If the difference between the first temperature value and the second temperature value is outside the preset temperature difference value, control the forehead temperature probe 12 and the ear temperature probe 11 to remeasure the temperature.

[0082] The first temperature value and the second temperature value can be fitted according to the following formula:

[0083]

[0084] Where T1 is the first temperature value currently detected by the forehead thermometer 12, and T2 is the second temperature value currently detected by the ear thermometer 11. The built-in algorithm of the control component can average the temperature values ​​detected by the forehead thermometer 12 and the ear thermometer 11. In this case, if the first temperature value T1 detected by the forehead thermometer 12 and the second temperature value detected by the ear thermometer 11 are less than or equal to a preset temperature difference (e.g., within 0.3℃), it means that the temperature values ​​detected by the two probes are relatively close, and the measurement results of the two probes can be considered reliable. The average of these two temperature values ​​can be used to calculate the output temperature value. The averaging method can comprehensively consider the measurement results of the forehead thermometer 12 and the ear thermometer 11, reducing errors caused by local temperature changes at a single measurement point, thus obtaining a value that more closely matches the actual human body temperature.

[0085] If the first temperature value T1 and the second temperature value T2 are outside the preset temperature difference, it is assumed that the two probes may be affected by factors such as sweat and changes in ambient temperature, which may lead to a large difference in the measurement results. In this case, the control component will control the forehead temperature probe 12 and the ear temperature probe 11 to re-measure the temperature.

[0086] The specific steps after re-measuring the temperature (after step S232) can be as follows:

[0087] S24: Determine whether the difference between the third temperature value obtained by the forehead temperature probe 12 and the fourth temperature value obtained by the ear temperature probe 11 is within a preset temperature difference value.

[0088] S241: If the difference between the third temperature value and the fourth temperature value is within a preset temperature difference value, fit the third temperature value and the fourth temperature value to obtain an output temperature value;

[0089] S242: If the difference between the third temperature value and the fourth temperature value is outside the preset temperature difference value, fit the first temperature value, the second temperature value, the third temperature value and the fourth temperature value to obtain the output temperature value.

[0090] The third and fourth temperature values ​​can be fitted using the following formula:

[0091]

[0092] Where T represents the output temperature value, T3 is the third temperature value (the temperature remeasured by the forehead temperature probe 12), and T4 is the fourth temperature value (the temperature remeasured by the ear temperature probe 11). After the two probes remeasure the temperature, the control component recalculates the absolute value of the difference between T3 and T4, i.e., |T3-T4|. If |T3-T4| is less than or equal to the preset temperature difference (e.g., 0.3℃), it can be considered that the temperature measurement is less affected by factors such as user sweat and changes in ambient temperature, and the temperature measurement can be considered relatively reliable. The average value of T3 and T4 can be taken as the output temperature value.

[0093] If, after re-measuring the temperature, the temperature difference between the two probes is still outside the preset temperature difference value, i.e., |T3-T4| is still greater than the preset temperature difference value, it indicates that there is still a large difference in the re-measurement results of the two probes. Factors such as sweat and changes in ambient temperature are difficult to avoid. In this case, the control component will include the temperature values ​​of the first and second measurements into the fitting formula to improve the accuracy and reliability of the measurement results.

[0094] At this point, the first, second, third, and fourth temperature values ​​can be fitted using the following formula:

[0095]

[0096] Where T is the output temperature value, T1 is the first temperature value, T2 is the second temperature value, T3 is the third temperature value, and T4 is the fourth temperature value. This fitting method is average value fitting, which can avoid the influence of outliers from a single measurement on the final result.

[0097] Alternatively, the first, second, third, and fourth temperature values ​​can be fitted using the following formula:

[0098]

[0099] Where T is the output temperature value, T1 is the first temperature value, T2 is the second temperature value, T3 is the third temperature value, and T4 is the fourth temperature value. The weight of the average of the first temperature value and the third temperature value. The weight of the average of the second and fourth temperature values, if ,but ,like ,but ,like ,but .

[0100] It should be noted that, if If the temperature difference between two measurements taken by the forehead thermometer 12 is less than that between two measurements taken by the ear thermometer 11, then the measurement result of the forehead thermometer 12 is considered more stable. Therefore, the average temperature measured by the forehead thermometer 12 is given a larger weight. .

[0101] like If the temperature difference between two measurements taken by the ear thermometer 11 is less than the temperature difference between two measurements taken by the forehead thermometer 12, then the measurement result of the ear thermometer 11 is considered more stable. Therefore, the average value of the temperature measurements taken by the ear thermometer 11 is given a larger weight. .

[0102] like Therefore, it is assumed that the temperature difference between two measurements taken by the forehead thermometer 12 is equivalent to the temperature difference between two measurements taken by the ear thermometer 11. Thus, the average values ​​of the two temperature measurements taken by the forehead and ear thermometers can be assigned the same weight. .

[0103] This weighted average calculation method comprehensively considers the stability of two measurements, giving greater weight to more stable results, thus obtaining a value that more closely reflects the true human body temperature. Under complex conditions such as user sweating or changes in ambient temperature, multiple temperature measurements and comprehensive fitting can improve the stability of the measurement results.

[0104] The following example illustrates the concept with a preset temperature difference of 0.3℃.

[0105] If the temperature value obtained by the forehead temperature probe 12 is 37.5℃ and the temperature value obtained by the ear temperature probe 11 is 37.8℃ during the first temperature measurement, and the temperature difference between the two is 0.3℃, which is within the allowable difference range, then the average value of 37.5℃ and 37.8℃, 37.65℃ (rounded to 37.7℃), is taken as the output temperature value.

[0106] If the temperature reading obtained by the forehead temperature probe 12 is 37.5℃ and the temperature reading obtained by the ear temperature probe 11 is 38℃ during the first temperature measurement, the temperature difference between the two is 0.5℃, which exceeds the preset temperature difference value of 0.3℃, then the temperature needs to be measured again.

[0107] Assuming that during the second temperature measurement, the temperature value obtained by the forehead temperature probe 12 is 37.6℃ and the temperature value obtained by the ear temperature probe 11 is 37.9℃, the temperature difference between the two is 0.3℃. Within the allowable difference range, the average value of 37.6℃ and 37.9℃, 37.75℃ (rounded to 37.8℃), is taken as the output temperature value.

[0108] If, during the second temperature measurement, the forehead temperature probe 12 obtains a temperature value of 37.7℃ and the ear temperature probe 11 obtains a temperature value of 38.1℃, and the temperature difference between the two is 0.4℃, which still exceeds the preset temperature difference value of 0.3℃, then the temperature values ​​of the first and second temperature measurements need to be included in the fitting formula.

[0109] If the temperature values ​​from both the first and second measurements are included in the simple average fitting formula... Take 37.825℃ (rounded to 37.8℃) as the output temperature value.

[0110] Alternatively, a weighted average can be used for fitting, as follows: , ,because The average of the two temperature measurements taken by the ear temperature probe 11 is given a larger weight, i.e. .

[0111] Assumption , ,but We take 37.9℃ as the output temperature value.

[0112] In summary, this control method uses the measurement results from two consecutive measurements for fitting calculation, which can reduce measurement errors caused by environmental factors (such as changes in ambient temperature, user sweat, etc.) and can perform a certain degree of environmental compensation, thereby improving the accuracy and reliability of the measurement.

[0113] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
