Technical Field

[0001] This application relates to the field of electronic pen technology, and more particularly to a temperature-measuring electronic pen. Background Technology

[0002] Electronic pens are widely used in various terminal devices with touch screens, such as tablet computers and touch screen mobile phones.

[0003] Currently, most electronic pen products on the market primarily focus on writing or drawing functions, and improvements typically concentrate on enhancing their writing or drawing performance, resulting in relatively limited functionality. For example, when using an electronic pen in conjunction with a tablet for work, if the task requires measuring body temperature, the user would need to put down the pen and use a thermometer or temperature gun to take the measurement.

[0004] Therefore, the limitations of electronic pen functionality cause inconvenience to users and reduce work efficiency. Utility Model Content

[0005] To address the aforementioned problems, this application provides a temperature-measuring electronic pen, comprising:

[0006] The pen body housing has a receiving cavity and an opening communicating with the receiving cavity;

[0007] A writing component, one end of which is housed in the receiving cavity, and the other end of which is a pen tip, which extends out of one end of the pen body housing;

[0016] The protective cover is detachably connected to the tail of the pen body housing. After the protective cover is connected to the pen body housing, the protective cover covers the opening.

[0017] Optionally, the temperature measuring electronic pen further includes a control motherboard and a compensation circuit. The temperature sensor is electrically connected to the control motherboard, and the compensation circuit is electrically connected between the temperature sensor and the control motherboard. The compensation circuit is used to compensate for and calibrate the measurement results of the temperature sensor.

[0018] Optionally, the temperature measuring electronic pen further includes a control motherboard and a wireless transmission device.

[0022] In this embodiment, in addition to expanding the functionality of the traditional electronic pen by adding a temperature sensor to enable writing and drawing, it can also measure temperature, thus improving work efficiency. Furthermore, by setting a shielding structure on the outside of the temperature sensor, the reliability and accuracy of temperature measurement are also improved.

[0031] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] Smart writing tools such as electronic pens or smart pens are typically used with electronic devices that have touchscreens to perform tapping, writing, or drawing on the touchscreen. Common electronic pens usually focus on improving their writing or drawing performance, and their functions are relatively limited.

[0033] The temperature-measuring electronic pens described in the various embodiments of this application integrate a temperature sensor, enabling the pen to not only perform traditional writing and drawing functions but also to measure body temperature. When a user needs to measure their body temperature, they can conveniently use the electronic pen without the need for a dedicated thermometer, thus improving work efficiency. The electronic pens in the embodiments of this application offer richer functionality and expand the applicable scenarios for electronic pens.

[0034] Example 1

[0035] like Figure 1 The diagram shown is a simplified structural composition of a temperature-measuring electronic pen according to an embodiment of this application. Figure 2 As illustrated, the writing component 10 of the temperature-measuring electronic pen in this embodiment of the application is provided with a sensing electrode. In some examples, the sensing electrode inside the writing component 10 can form an equivalent capacitance with the capacitive layer on the touch screen. The electronic device can respond by detecting the capacitance change between the sensing electrode of the writing component 10 and the contact point with the screen, displaying the trajectory, thickness, and other usage status of the electronic pen. The pen body shell 11 is a long, straight cylindrical shell with a hollow receiving cavity 111 along its length. This receiving cavity 111 is used to install hardware devices such as the pressure-sensitive module, battery, and main control board of the electronic pen. One end of the writing component 10 is housed in the receiving cavity 111, and the other end forms a pen tip that extends outside the pen body shell 11. When the writing component 10 is connected to the pen body shell 11, the opening formed at this end of the receiving cavity 111 can be blocked. Furthermore, the pen body shell 11 also has an opening 112 communicating with the receiving cavity 111. This opening 112 can be located on the side wall or end of the pen body shell 11. In this embodiment, a temperature sensor 12 is also installed within the receiving cavity 111. The temperature sensor 12 can be a contact sensor (e.g., an NTC temperature sensor), which measures body temperature data through direct contact with human skin. Alternatively, the temperature sensor 12 can be a non-contact sensor (e.g., a photoelectric temperature sensor), which avoids the influence of sweat, oil, or other substances on the surface of human skin on the measurement results. It is understood that, as... Figure 3 As illustrated, regardless of the type of temperature sensor 12, it includes a connected sensing portion 121 and a circuit portion 122. The sensing portion 121 receives thermal radiation signals from the object being measured, and the circuit portion 122 converts the thermal radiation signals into electrical signals. For example, in a contact sensor, the sensing portion 121 directly contacts the skin of the person being measured to receive thermal radiation signals. In a non-contact sensor, the sensing portion 121 can receive infrared signals from the person being measured. Regardless of the location of the temperature sensor 12 within the receiving cavity 111, at least the circuit portion 122 is located within the receiving cavity 111. When measuring temperature, the sensing portion 121 faces the skin, allowing the thermal radiation signals to pass through the opening 112 and be transmitted to the sensing portion 121.

[0036] Furthermore, with the development of electronic pens, the number of integrated circuits within the pen body 11 is increasing, including circuits for controlling writing and drawing, charging circuits, and power supply circuits. To avoid these circuits interfering with the temperature sensor 12, in conjunction with... Figure 1As illustrated, in this embodiment of the application, the temperature sensor 12 is externally provided with a shielding structure 13. The shielding structure 13 is at least used to shield or reduce electromagnetic interference signals from affecting the circuit portion 122. Exemplarily, the shielding structure 13 covers the circuit portion 122 of the temperature sensor 11 to isolate electromagnetic interference signals from other electronic components. It is understood that, to ensure the normal operation of the temperature sensor 12, the shielding structure 13 should avoid the sensing portion 121 of the temperature sensor 12, leaving the sensing portion 121 exposed. In some embodiments, as the shielding structure 13, it can also be electrically connected to the common ground (GND) on the main control board or other arbitrary circuit board of the temperature-measuring electronic pen, allowing the induced charge to be discharged to ground, further preventing electromagnetic interference from other circuits or electronic components outside the temperature sensor 12, thereby helping to improve the temperature measurement reliability and accuracy of the temperature sensor 12.

[0037] Therefore, the temperature measuring electronic pen of this application embodiment not only expands and adds temperature measuring function and improves work efficiency on the basis of traditional electronic pens, but also further improves the reliability and accuracy of temperature measurement.

[0038] Example 2

[0039] In one embodiment, the temperature sensor 12 in the aforementioned embodiment of this application can be a photoelectric sensor that does not require contact with human skin; specifically, it can be an infrared photoelectric sensor. The infrared photoelectric sensor receives infrared radiation from the human body through its sensing element. After the infrared radiation enters the sensor, it interacts with the infrared detector inside the sensor, which converts the received infrared radiation into an electrical signal. This electrical signal is then processed by a signal processing circuit to obtain the human body temperature.

[0040] By employing an infrared photoelectric sensor as a non-contact temperature sensor 12, human body temperature can be measured quickly and conveniently in situations where high temperature measurement accuracy is not required.

[0041] Furthermore, in one embodiment, based on the above-described embodiment two, such as Figure 1 As illustrated, when an infrared photoelectric sensor is used as the temperature sensor 12, the temperature measuring electronic pen of this embodiment also includes a filter 14. The filter 14 can be fixed to the part of the pen body housing 11 with an opening 112 by means of adhesive or snap-fit, and the filter 14 is located in the light path of the temperature sensor 12. For example, the filter 14 can be arranged at the front end of the sensing part 121 of the temperature sensor 12, and the heat radiation wave emitted by the human body is received by the sensing part 121 of the temperature sensor 12 after passing through the filter 14.

[0042] Therefore, the filter 14 can filter out stray waves other than infrared light, which can improve the accuracy of temperature measurement. In addition, the filter 14 can also provide scratch and dust protection for the temperature sensor 12.

[0043] Example 3

[0044] In one embodiment, the shielding structure 13 in the aforementioned embodiment 1 of this application can be of various different structural forms. For example, it can be a metal coating applied to the inner wall of the receiving cavity 111 by brushing, a metal plating layer attached to the inner wall of the receiving cavity 111 by a coating process, or a metal shell manufactured by machining. The metal material of the shielding structure 13 can be copper, silver, or an alloy. In addition, the shielding structure 13 can also be a composite structure doped with a conductive medium (such as conductive adhesive), such as conductive tape. Technicians can select the appropriate material based on a combination of shielding performance and material price.

[0045] The shielding structures 13 described above, with their different structural forms, can be applied to pen housings 11 of different sizes. For example, when the pen housing 11 is thin and its receiving cavity 111 has a small space, the shielding structure 13 can be designed as a metal coating or metal plating. In this case, the metal coating or metal plating is directly processed onto the inner wall of the receiving cavity 111 through physical or chemical molding processes, without the need for additional assembly steps. When the pen housing 11 is thick and its receiving cavity 111 has a large space, the shielding structure 13 can be designed as a metal shell, which is then inserted into the receiving cavity 111 for fixation.

[0046] Therefore, the shielding structures 13 with different structural forms in the embodiments of this application can meet the shielding requirements of the temperature sensor 12 in the pen body shell 11 with different sizes.

[0047] Example 4

[0048] In one embodiment, the pen body shell 11 in the aforementioned embodiment 1 of this application has the following shape: Figure 2 As shown, one end of the pen body shell 11 is connected to the writing component 10, and the other end of the pen body shell 11 is the tail. The tail of the pen body shell 11 is provided with an opening 112, which communicates with the receiving cavity 111. When the temperature sensor 12 is installed and fixed at the tail of the pen body shell 11, the sensing part 121 of the temperature sensor 12 also faces the tail, so as to measure the body temperature of the human body.

[0049] This arrangement of fixing the temperature sensor 12 to the tail of the pen body shell 11 can also avoid affecting the placement of other electronic components and improve the utilization rate of the internal space of the pen body shell 11.

[0050] Furthermore, in one embodiment, based on the above-described embodiment four, such as Figure 1As illustrated, the temperature measuring electronic pen of this application embodiment also includes a protective cover 15. The protective cover 15 is detachably connected to the tail of the pen body housing 11. For example, threads are provided at the tails of both the protective cover 15 and the pen body housing 11 to achieve a detachable connection between the two, or a snap-fit ​​structure that can engage with each other can also be provided at the tails of the protective cover 15 and the pen body housing 11 to achieve a detachable connection between the two.

[0051] When the temperature measurement function of the electronic pen is not needed, connect the protective cover 15 to the tail of the pen body housing 11. At this time, the protective cover 15 blocks the opening 112, and the protective cover 15 can protect the temperature sensor 12 located in the receiving cavity 111. When the temperature measurement function of the electronic pen is needed, remove the protective cover 15 from the pen body housing 11 to expose the sensing part 121 of the temperature sensor 12.

[0052] Example 5

[0053] In one implementation, such as Figure 1 As illustrated in the illustration, the temperature-measuring electronic pen in the aforementioned embodiment of this application also includes a control motherboard 16. A processor 161 can be soldered onto the control motherboard 16. Simultaneously, a temperature sensor 12 can also be soldered onto the control motherboard 16. The temperature sensor 12 and the processor 161 are electrically connected through traces on the control motherboard 16. Furthermore, the control motherboard 16 can also be equipped with signal processing circuitry related to temperature measurement, to at least amplify and filter the electrical signal from the temperature sensor 12. In this embodiment, the processor 161 used on the control motherboard 16 can be a general-purpose MCU (Micro Control Unit) chip, or it can be a combination of MCU and I... 2 A System-on-a-Chip (SoC) chip integrating Inter-Integrated Circuit (IoC), Serial Peripheral Interface (SPI), UART (Universal Asynchronous Receiver / Transmitter), and AD conversion. These processors 161 can process signals from the temperature sensor 12 to convert the thermal radiation acquired by the temperature sensor 12 into temperature values.

[0054] like Figure 4As illustrated, the temperature-measuring electronic pen in this embodiment of the application also includes a compensation circuit 17. The compensation circuit 17 is electrically connected between the temperature sensor 12 and the control motherboard 16. When the electrical signal output by the temperature sensor 12 passes through the compensation circuit 17, the compensation circuit 17 can compensate and calibrate the electrical signal transmitted by the temperature sensor 12 to reduce measurement errors. Specifically, for example, the compensation circuit 17 can be a thermistor circuit, which monitors the ambient temperature of the temperature-measuring electronic pen to compensate and calibrate the measurement results of the temperature sensor 12, thereby improving the accuracy of the measurement results.

[0055] Furthermore, in one embodiment, the temperature-measuring electronic pen in the aforementioned embodiment 1 of this application also includes a control motherboard 16, such as... Figure 4 As illustrated, the temperature-measuring electronic pen in this embodiment also includes a wireless transmission device 18. The wireless transmission device 18 can be a Bluetooth chip, WiFi chip, NFC chip, or 2.4G broadcast chip, etc. These wireless transmission devices 18 can be electrically connected to the control motherboard 16. Using their respective wireless communication protocols, the wireless transmission devices 18 can wirelessly connect with terminal devices such as tablets, smartphones, and smartwatches, in addition to the temperature-measuring electronic pen. This temperature-measuring electronic pen, which also integrates a wireless transmission device 18, can transmit the measurement results to the terminal device via the wireless transmission device 18 when measuring human body temperature data.

[0056] When faced with the task of measuring, recording, and statistically analyzing a large amount of human body temperature data, the electronic temperature measuring pen of this application embodiment can more efficiently complete the work of collecting and analyzing body temperature data.

[0057] Furthermore, in one embodiment, based on the above-described embodiment five, such as Figure 1 and Figure 4 As illustrated, the temperature-measuring electronic pen of this embodiment also includes a button 19, which is electrically connected to the control motherboard 16. The button 19 can be located in a convenient position in the middle of the pen body for user operation, or it can be located in other parts. Furthermore, the button 19 can be a mechanical contact switch or a capacitive touch button, among other structural forms.

[0058] When there is only one button 19, it can serve the dual functions of activating the temperature sensor 12 and triggering the wireless transmission device 18 to send measurement results. For example, a single click or short press activates the temperature sensor 12, while a double click or long press triggers the wireless transmission device 18 to send measurement results. In this button 19 design, two functions can be achieved simultaneously with a single button 19, which helps reduce the number of buttons, lowers the material cost of hardware, and reduces assembly steps.

[0059] When there are two buttons 19, they can be used to activate the temperature sensor 12 and trigger the wireless transmission device 18 to send the measurement results, respectively. In this button 19 design, the two buttons 19 independently control their corresponding functions, and when either button 19 fails, the other function can still function normally.

[0060] Furthermore, in one implementation, based on the foregoing embodiments, such as Figure 4 As shown, when the temperature measuring electronic pen also includes button 19, it may also include a distance sensor 20. The distance sensor 20 is installed and fixed inside the receiving cavity 111 and is electrically connected to the control motherboard 16. The distance sensor 20 can be a photoelectric distance sensor or an ultrasonic sensor, or other different types of sensors. The distance sensor 20 can directly measure the first distance between itself and the object to be measured. After the distance sensor 20 is installed and fixed, the second distance between it and the temperature measuring sensor 12 remains unchanged. Therefore, the control motherboard 16 can easily calculate the real-time distance between the sensing part 121 of the temperature measuring sensor 12 and the object to be measured based on the first and second distances mentioned above. When the user uses the temperature measuring electronic pen to measure temperature, the real-time distance will decrease or increase accordingly as the hand moves the temperature measuring electronic pen closer to or further away from the object to be measured. When the real-time distance is at a preset distance (e.g., 1cm~3cm), pressing button 19 will activate the temperature measuring sensor 12 and trigger the wireless transmission device 18 to send the measurement result.

[0061] Therefore, in this embodiment, a distance sensor 20 can also be installed to control the activation of the temperature measurement function within a suitable distance range, thereby reducing the interference of distance factors on the accuracy of the measurement results.
