Technical Field

[0001] The utility model relates to the technical field of temperature and humidity sensors, and particularly relates to a stainless steel analog temperature and humidity sensor. Background Technique

[0002] In the field of temperature and humidity sensors, the existing technology mainly adopts a plastic shell design. This design is widely used because of its low cost and easy manufacturing. Sensors with plastic shells are usually used in indoor environments such as homes and offices, where the temperature and humidity changes are relatively mild, and the requirements for the temperature resistance and humidity resistance of the sensors are not high. The application scenarios of plastic shell sensors mainly include daily environmental monitoring, smart home systems, and simple industrial process control, etc. These sensors can meet the basic temperature and humidity measurement requirements, but in specific industrial environments or outdoor applications, their performance may be limited.

[0003] Although the temperature and humidity sensors with plastic shells perform well in general environments, they have obvious deficiencies when facing high-temperature and high-humidity environments. Plastic materials are prone to deformation at high temperatures, and their humidity resistance is limited, resulting in the sensors being unable to work stably under these extreme conditions. The temperature measurement range of existing sensors is usually limited between -40°C and 80°C, which restricts their application in a wider temperature range. In application scenarios that require long-term monitoring of high-humidity environments or temperatures exceeding 80°C, such as industrial ovens, steam pipelines, or tropical climate regions, the existing technology cannot provide reliable measurement results. Therefore, for temperature and humidity sensors that need to operate stably in more extreme environments, the existing technology shows obvious limitations. Content of the Utility Model

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Please refer to Figure 1 , the present invention provides a technical solution: a stainless steel analog temperature and humidity sensor, comprising: a rear section of stainless steel 1, a front section of stainless steel 2, a sealing mechanism, an end plugging mechanism, and a monitoring mechanism. The rear section of stainless steel 1 is arranged in a cylindrical structure; one side of the front section of stainless steel 2 is screwed to the rear section of stainless steel 1; the sealing mechanism is arranged in the front section of stainless steel 2 and the rear section of stainless steel 1; the end plugging mechanism is arranged on one side of the front end of stainless steel and the rear section of stainless steel 1; the monitoring mechanism penetrates through the rear section of stainless steel 1 and extends to the front end of stainless steel.

[0017] In the specific implementation process, it should be noted that the rear section of stainless steel 1, as a cylindrical structure, provides the main support and protection for the monitoring mechanism. The sealing mechanism is located between the front section of stainless steel 2 and the rear section of stainless steel 1, and its function is to ensure the isolation between the inside and the outside environment of the sensor, prevent external moisture and impurities from entering the inside, and affect the measurement accuracy. The end plugging mechanism is arranged on one side of the front end of stainless steel and the rear section of stainless steel 1 to further enhance the sealing performance of the sensor and ensure the stability of the internal environment of the sensor. The analog measurement range of this device is -40 to 120 °, suitable for long-term measurement in an environment with a humidity range of 0 to 99%, and can resist the effect of short-term water immersion.

[0018] The monitoring mechanism penetrates through the rear section of stainless steel 1 and extends to the front end of stainless steel. The monitoring mechanism can sense the changes in temperature and humidity in the environment, so as to realize the real-time monitoring of the environmental temperature and humidity. The rear section of stainless steel 1 and the front section of stainless steel 2 provide strong physical protection, the sealing mechanism and the end plugging mechanism ensure the stability of the internal environment of the sensor, and the monitoring mechanism is responsible for sensing and transmitting temperature and humidity data, jointly realizing the accurate monitoring of the environmental temperature and humidity by the sensor.

[0019] In some examples, further, the end plugging mechanism includes: a stainless steel filter element 3 and a wire locking cap 4. The stainless steel filter element 3 is screwed on the front section of stainless steel 2; the wire locking cap 4 is screwed on one side of the rear section of stainless steel 1.

[0020] In the specific implementation process, it should be noted that the function of the stainless-steel filter element 3 is to filter, which can prevent particulate matter and impurities in the external environment from contaminating the monitoring mechanism, while allowing air to circulate to ensure that the temperature and humidity sensor can accurately measure the temperature and humidity data of the internal environment. The wire locking cap 4 is used to fix and protect the internal wires, preventing the wires from being damaged or falling off due to external forces, and ensuring the stability and reliability of the sensor. The stainless-steel filter element 3 and the wire locking cap 4 work together. On the one hand, they ensure the cleanliness of the internal environment of the sensor and accurate measurement, and on the other hand, they ensure the firm connection of the sensor wires, jointly maintaining the normal operation of the sensor and the accurate transmission of data.

[0021] In some examples, furthermore, the monitoring mechanism includes: an analog circuit main board 5, a wire 6, and a temperature and humidity filter element small board 7. The analog circuit main board 5 is arranged inside the stainless-steel rear section 1; the wire 6 enters from the wire locking cap 4, passes through the inside of the stainless-steel rear section 1, and extends to the inside of the stainless-steel front section 2; one end of the temperature and humidity filter element small board 7 is connected to one end of the wire 6 and is located inside the stainless-steel filter element 3.

[0022] In the specific implementation process, it should be noted that the analog circuit main board 5 is responsible for processing the temperature and humidity signals. The function of the wire locking cap 4 is to protect the wire 6 and ensure its sealing with the external environment. The wire 6 passes through the inside of the stainless-steel rear section 1 to ensure the stability and security of signal transmission. The temperature and humidity filter element small board 7 is located inside the stainless-steel filter element 3, and one end of it is connected to one end of the wire 6. The temperature and humidity filter element small board 7 is integrated with temperature and humidity sensing elements, which are responsible for real-time monitoring of the temperature and humidity in the environment. When the temperature and humidity in the environment change, the sensing elements convert these changes into electrical signals and transmit them to the analog circuit main board 5 through the connected wire 6. After receiving these electrical signals, the analog circuit main board 5 further processes and outputs them for external devices to read and analyze. The analog circuit main board 5, the wire 6, and the temperature and humidity filter element small board 7 work together to ensure the accurate acquisition and stable transmission of temperature and humidity data, thereby realizing the effective monitoring of the environmental temperature and humidity.

[0023] In some examples, furthermore, the sealing mechanism includes: a silicone layer and a silicone potting layer. The silicone layer is coated on the surface of the analog circuit main board 5; the silicone potting layer is arranged inside the stainless-steel front section 2.

[0024] In the specific implementation process, it should be noted that the silicone layer is coated on the surface of the analog circuit main board 5, and its function is to provide a protective film to prevent moisture and impurities from directly contacting the circuit board, thereby protecting the circuit from the effects of moisture and contamination. Due to its good adhesion and sealing properties, the silicone layer can effectively isolate the adverse effects of the external environment on the analog circuit main board 5 and ensure the stable operation of the circuit. The silicone potting layer plays a sealing role, preventing the external environment from directly entering the interior of the sensor, and also helps to fix the internal components and reduce the impact of vibration and shock on the performance of the sensor. The setting of the silicone potting layer further enhances the sealing performance of the sensor, ensuring that the temperature and humidity sensing elements can work in a stable and controlled environment, thereby improving the accuracy and reliability of the measurement. The silicone layer and the silicone potting layer together constitute the sealing mechanism of the sensor to protect the analog circuit main board 5 from moisture and contamination. Through the setting of the potting layer, the stability of the internal environment of the sensor is ensured, providing a suitable working environment for the temperature and humidity sensing elements, and jointly ensuring the long-term stable operation of the sensor and the accuracy of the measurement data.

[0025] In some examples, furthermore, a high-temperature resistant silicone layer is provided on the outer wall of the wire 6. The high-temperature resistant silicone layer is evenly coated on the outer wall of the wire 6. In order to protect the wire 6 in a high-temperature environment, when the sensor is placed in a high-temperature environment, the high-temperature resistant silicone layer can effectively isolate the external high temperature and protect the wire 6 from being directly baked or burned. Even under extreme temperature conditions, the wire 6 can maintain the integrity of its structure and electrical performance, ensuring the stability and reliability of signal transmission. The high-temperature resistant silicone layer also has excellent electrical insulation properties, which can prevent short circuits between the wires 6 and electrical contact between the wire 6 and other metal components of the sensor, thereby improving the safety and durability of the sensor. The high-temperature resistant silicone layer provides an additional protective layer for the wire 6, enabling it to work normally in a high-temperature environment while ensuring the stability and safety of signal transmission inside the sensor.

[0026] In some examples, further, a condensation prevention layer is provided inside the silicone potting layer. A condensation prevention layer is added inside the silicone potting layer. The condensation prevention layer is to prevent the formation of condensed water droplets on the inner surface of the sensor when the temperature changes. When the external environmental humidity is high and the temperature inside the sensor is lower than the external environmental temperature, condensed water droplets may form on the inner surface of the sensor due to the temperature difference. If the condensed water droplets directly contact the circuit components, it may cause a short circuit or a decrease in performance of the circuit. By providing a condensation prevention layer inside the silicone potting layer, the condensed water droplets can be effectively absorbed and dispersed, preventing them from forming large water droplets on the inner surface of the sensor. The condensation prevention layer can quickly absorb the condensed water vapor and evenly disperse it, thus avoiding the formation of water droplets. The silicone potting layer and the condensation prevention layer work together to provide sealing protection. Through the special function of the condensation prevention layer, it is ensured that the sensor can maintain stable performance and accurate measurement results even in a high-humidity environment, improving the reliability and durability of the sensor.
