Description

Technical Field

[0001] This utility model relates to the field of temperature measuring device technology, and more specifically, to a thermally conductive silicone-wrapped temperature measuring device. Background Technology

[0002] Thermometers, as core tools for temperature measurement, are widely used in various fields such as human health monitoring, environmental monitoring, and industrial production. Their core principle is based on the physical properties of matter, such as thermal expansion and contraction, thermoelectric effect, and infrared thermal radiation, converting temperature changes into intuitively readable scales or digital signals. Currently, common thermometers on the market mainly include mercury thermometers, electronic thermometers, infrared thermometers, and thermocouple thermometers: Mercury thermometers rely on the thermal expansion and contraction of mercury to measure temperature. Although they are low-cost, they have a slow response time, are easily broken, and mercury leakage poses a safety hazard; electronic thermometers convert temperature signals using the characteristics of thermistors or thermocouples, providing an intuitive digital display, but the contact effect between the probe and human skin directly affects the measurement accuracy; infrared thermometers use infrared radiation energy to calculate temperature, requiring no direct contact and are convenient to use, but are easily affected by factors such as ambient temperature and measurement distance; thermocouple thermometers measure temperature based on the thermoelectric potential difference between two different metals, suitable for high-temperature industrial scenarios, but difficult to adapt to the precise temperature measurement needs of human bodies.

[0003] In human body temperature measurement scenarios, existing thermometers generally suffer from the following technical challenges: Firstly, common temperature measurement sites on the human body (such as the armpit, ear canal, and forehead) are mostly curved or irregular in shape. Traditional thermometer probes are often rigid structures, making it difficult to achieve a tight fit with the skin, resulting in the formation of tiny air gaps between the probe and the skin. Air has a thermal conductivity of only 0.024 W / (m·K), providing significant insulation and severely hindering heat transfer, causing temperature measurement response delays and leading to lower readings and larger errors. Secondly, some temperature measurement devices using flexible probes have encasing materials with poor thermal conductivity, failing to quickly conduct heat from the skin to the sensing element, further exacerbating the problem of insufficient temperature measurement accuracy. Furthermore, the connection structure between the probe and the main body of some temperature measurement devices is unstable, prone to loosening over long-term use, affecting the device's lifespan and safety. Therefore, a thermally conductive silicone-wrapped temperature measurement device is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a thermally conductive silicone-wrapped temperature measuring device, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a thermally conductive silicone-wrapped temperature measuring device, including a thermometer body, on which a temperature measuring component is provided; The temperature measuring component includes an extension strip disposed at one end of the thermometer body. The extension strip is made of elastic insulating material. A thermally conductive silicone sleeve is disposed at one end of the extension strip. A temperature measuring element for temperature measurement is disposed inside the thermally conductive silicone sleeve. Gel is bonded to the outside of the thermally conductive silicone sleeve so that the thermally conductive silicone sleeve is adhered to the user's skin through the gel for temperature detection. The temperature measuring element is equipped with a temperature sensor for temperature sensing, and the temperature sensor is installed at one end of the extension strip.

[0006] Optionally, in a possible implementation, a connecting post is provided at the end of the extension strip away from the thermally conductive silicone sleeve, and a limiting sleeve is provided at the end of the thermometer body facing the extension strip. The connecting post extends into the limiting sleeve and is threadedly connected to the limiting sleeve. The connecting post is connected to the thermometer body via a wire. An installation groove is provided on the thermometer body, and an anti-slip pad is provided on the inner wall of the installation groove. A pad is snapped into the installation groove, and a display screen is provided on the pad. Optionally, in a possible implementation, a button is provided at one end of the display screen, both the button and the display screen are embedded in the pad, the vertical cross-sectional shape of the thermally conductive silicone sleeve is set to an arc shape, and the surface of the thermally conductive silicone sleeve is provided with anti-slip texture, the thermally conductive silicone sleeve is bonded to the outside of the extension strip, and the temperature measuring element is welded and fixed to the temperature sensor. The technical effects and advantages of this utility model are as follows: By wrapping the temperature measuring element with an arc-shaped thermally conductive silicone sleeve, the flexibility and elasticity of the thermally conductive silicone allow the temperature measuring end to fit tightly against irregular curved surfaces such as the armpit and ear canal, completely eliminating air gaps between the probe and the skin. On the other hand, the high thermal conductivity of the thermally conductive silicone significantly improves heat transfer efficiency, allowing heat from the skin to be quickly and evenly conducted to the temperature sensor, effectively avoiding problems such as low readings or slow response caused by delayed heat conduction. The anti-slip texture on the surface of the thermally conductive silicone sleeve increases friction between the temperature measuring tip and the skin, preventing the device from slipping off during measurement. This is especially suitable for temperature measurement scenarios involving infants, the elderly, and other individuals with lower cooperation levels. Simultaneously, the thermally conductive silicone material has excellent biocompatibility, is non-toxic, odorless, soft, and skin-friendly, causing no irritation upon direct skin contact. This avoids the squeezing or scratching damage that can occur with hard probes, improving safety and comfort. Furthermore, the extension strip is connected to the thermometer body via a threaded connection post, ensuring a stable and secure connection that is less prone to loosening. Compared to adhesive connections, this facilitates easier disassembly, maintenance, and replacement of the temperature measuring components, extending the overall lifespan of the device.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Example 1 This embodiment discloses a thermally conductive silicone-wrapped temperature measuring device, which aims to solve the problems of poor fit and low heat conduction efficiency of existing temperature measuring devices when in contact with irregular temperature measuring parts of the human body, resulting in slow temperature measurement response and inaccurate readings. At the same time, it optimizes the ease of assembly and feel of the device.

[0015] Specifically, the thermally conductive silicone-wrapped temperature measuring device includes a thermometer body 1, which integrates a temperature measuring component for realizing the core temperature measuring function, and is also equipped with a display and control structure for easy operation and reading.

[0016] An extension strip 2 is provided on the side of the thermometer body 1 near the measuring end. The extension strip 2 is made of an elastic insulating material, such as rubber or silicone, to make it flexible and ensure the extension range of the measuring end. A thermally conductive silicone sleeve 3 is glued and fixed to the outer side of the free end of the extension strip 2. Figure 3As shown, the vertical cross-sectional shape of the thermally conductive silicone sleeve 3 is set to be arc-shaped, which is adapted to the contour of the curved temperature measurement parts such as the ear canal and armpit. The outer surface of the thermally conductive silicone sleeve 3 is integrally formed with uniformly distributed anti-slip textures 12, which can effectively increase the friction between the thermally conductive silicone sleeve 3 and the skin during temperature measurement and prevent the device from slipping off. Furthermore, gel can be adhered to the outside of the thermally conductive silicone sleeve 3 so that the thermally conductive silicone sleeve 3 sticks to the user's skin and ensures the heat conduction detection effect.

[0017] A temperature sensing element 4 is embedded inside the thermally conductive silicone sleeve 3. The temperature sensing element 4 uses a high-temperature resistant ceramic base, on which a temperature sensor 5 is welded and fixed. The temperature sensor 5 is a high-precision thermistor, and its sensing end is tightly fitted to the inner wall of the thermally conductive silicone sleeve 3 to ensure rapid heat transfer. The temperature sensor 5 is installed at the end of the extension strip 2, and its pins are connected to subsequent circuits through pre-set wire channels inside the extension strip 2.

[0018] Example 2 Based on Example 1, to achieve a stable connection between the extension strip 2 and the thermometer body 1, such as... Figure 3 , Figure 4 As shown, the end of the extension strip 2 away from the thermally conductive silicone sleeve 3 has an integrally formed connecting post 6, with external threads on the outer side of the connecting post 6. The end of the thermometer body 1 facing the extension strip 2 has an integrally formed limiting sleeve 7, with internal threads on the inner wall of the limiting sleeve 7 matching the external threads of the connecting post 6. The connecting post 6 extends into the limiting sleeve 7 and is threadedly connected to it. During assembly, the extension strip 2 can be rotated to secure it, making disassembly convenient and facilitating subsequent maintenance and replacement of the temperature measuring components. Simultaneously, the connecting post 6 has a wire through-hole. The wires connecting the temperature measuring element 4 and the temperature sensor 5 pass through this through-hole and connect to the control circuit inside the thermometer body 1, enabling signal and power transmission.

[0019] like Figure 1 , Figure 4As shown, the thermometer body 1 has a mounting groove 8 on its front. A rubber anti-slip pad is attached to the inner wall of the mounting groove 8, with fine textured surfaces to increase friction between the pad 9 and the mounting groove 8, preventing the pad 9 from loosening. The pad 9, made of ABS engineering plastic, is snapped into the mounting groove 8. Its dimensions are matched to the dimensions of the mounting groove 8. After snapping, the outer surface of the pad 9 is flush with the outer surface of the thermometer body 1, ensuring the overall aesthetics and grip feel of the device. A display screen 10 and buttons 11 are embedded in the pad 9. The display screen 10 is an LCD screen that clearly displays the measured temperature value, measurement time, and other information for quick user reading. The buttons 11 are located on one side of the display screen 10, specifically two independent buttons: a power-on / power-off button and a measurement confirmation button. The buttons 11 are made of silicone, providing clear tactile feedback, and a sealing gasket is provided at the connection between the buttons 11 and the pad 9, providing a certain degree of waterproofing and dustproofing.

[0020] The specific working principle is as follows: First, weld and fix the temperature sensor 5 onto the temperature measuring element 4. Then, embed the temperature measuring element 4 into the inside of the thermally conductive silicone sleeve 3, ensuring that the temperature sensor 5 fits tightly against the inner wall of the thermally conductive silicone sleeve 3. Next, glue and fix the thermally conductive silicone sleeve 3 to the free end of the extension strip 2. Align the connecting post 6 with the limiting sleeve 7 of the thermometer body 1, and achieve a fixed connection between the extension strip 2 and the thermometer body 1 by rotating the thread. At the same time, pass the wire through the connecting post 6 and connect it to the internal circuit of the thermometer body 1. Finally, snap the pad 9 into the mounting groove 8 to complete the assembly of the display screen 10 and the button 11.

[0021] During use, the user starts the device by pressing the power button on button 11 and attaches the temperature measuring end with the thermally conductive silicone sleeve 3 to the target temperature measuring area, such as the ear canal or armpit. Because the thermally conductive silicone sleeve 3 has an arc-shaped structure and is flexible and elastic, it can closely fit the irregular curved surface of the human body. At the same time, the anti-slip texture 12 on its surface can prevent the device from slipping off during measurement. The heat from the measuring area is quickly transferred to the temperature sensor 5 through the thermally conductive silicone sleeve 3. The high thermal conductivity of the thermally conductive silicone sleeve 3 effectively eliminates the air insulation layer between the probe and the skin, avoiding heat conduction delay. The temperature sensor 5 converts the temperature signal into an electrical signal, which is transmitted to the control circuit inside the thermometer body 1 through the wire. After the circuit processes the signal, it displays the temperature value on the display screen 10. The user can directly read the measurement result through the display screen 10. After the measurement is completed, the user can press the power button again to turn off the device, or the device will automatically turn off after a preset time.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
