The purpose of this storage is to maintain seed viability for a longer period, extend their shelf life, and ensure variety quality and sowing quality to meet production requirements for both quantity and quality. Warehouse temperature and humidity are essential conditions for seed storage; therefore, it is crucial to install temperature and humidity sensors in appropriate locations within the warehouse for continuous 24-hour monitoring.

[0003] Beyond seed storage, various industries are increasingly emphasizing product production, goods management, and warehousing. Many warehouses store vital materials such as tobacco leaves, textiles, medicinal herbs, and food. To maintain the quality of stored goods and create a suitable storage environment, it's necessary to prevent adverse effects from the external climate when the temperature and humidity inside the warehouse are appropriate, and to adjust the temperature and humidity promptly when they become unsuitable. Therefore, establishing a real-time temperature and humidity monitoring system and maintaining complete historical temperature data has become an industry standard.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this invention is to provide a temperature and humidity sampling device to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively improves detection accuracy, and effectively improves the convenience of installation and positioning.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model provides a temperature and humidity sampling device, as shown in Figures 1-4, comprising: a device body 1, a probe 2, a gas collection hood 3, a forced convection mechanism, and a magnetic positioning mechanism 8. The probe 2 is mounted on the device body 1 to collect temperature and humidity data from the environment in real time. The probe 2 enables the temperature and humidity sampling device to collect environmental temperature and humidity data in real time, providing a foundation for obtaining accurate environmental temperature and humidity information. This helps warehouse managers to understand the temperature and humidity conditions within the warehouse in a timely manner, and to better manage and protect stored goods. The gas collection hood 3 is fixedly connected to the device body 1 and covers the outside of the probe 2. The gas collection hood 3 is provided with an air inlet 7 and an air outlet. Covering the outside of the probe 2, the gas collection hood 3 firstly provides physical protection for the probe 2, reducing direct damage from external factors and extending its service life. Simultaneously, the air inlet 7 and air outlet create an airflow channel, providing conditions for the forced convection mechanism to guide airflow, allowing air from more different locations to come into contact with the probe 2, thereby collecting more comprehensive environmental temperature and humidity information and improving detection accuracy. A forced convection mechanism is installed inside the air collection hood 3 to drive external airflow across the surface of the probe head 2. This mechanism overcomes the limitations of poor airflow and effectively solves the problem of inaccurate detection caused by stagnant air. By forcing airflow, the probe head 2 can quickly acquire temperature and humidity data from different areas, improving detection accuracy and ensuring real-time and accurate monitoring of warehouse temperature and humidity.

[0024] In a preferred embodiment, the forced convection mechanism includes an exhaust fan 4 mounted on the upper part of the air collection hood 3. The exhaust fan 4 can generate directional suction, causing external air to enter the air collection hood 3 from the air inlet 7, pass over the surface of the probe head 2, and be discharged from the air outlet, forming a stable airflow path. This forced airflow ensures that the air around the probe head 2 is constantly renewed, avoiding the influence of local air temperature and humidity deviations on the detection results, and further improving the accuracy and timeliness of temperature and humidity detection.

[0025] In a preferred embodiment, the forced convection mechanism further includes a turbulence-inducing mechanism disposed on the outer periphery of the probe head 2 to prolong the residence time of air on the surface of the probe head 2. This extended residence time allows the temperature and humidity sensor to have more sufficient contact time with the air. This means that changes in temperature and humidity in the air can be sensed more accurately, capturing more precise data and further improving the accuracy and reliability of detection, providing strong support for precise control of the warehouse environment.

[0026] In a preferred embodiment, the airflow disturbance mechanism includes at least one baffle 5, which guides air to the surface of the probe head 2. The baffle 5 directs the disordered airflow to the surface of the probe head 2, allowing the air to contact the probe head 2 in a more orderly and thorough manner. This ensures that all parts of the probe head 2 can fully contact the air, reducing blind spots and improving the comprehensiveness and accuracy of the detection from a spatial perspective.

[0027] In a preferred embodiment, the baffle 5 is a conical tubular structure, and a vent 6 is provided at the contact point between the baffle 5 and the probe 2. The conical tubular structure of the baffle 5 facilitates the convergence and guidance of air, improving airflow efficiency and directionality. The vent 6 ensures that air can smoothly reach the surface of the probe 2 while allowing some air to escape from the side, increasing the diversity of air contact with the probe 2 surface and preventing excessive air accumulation or dead zones in local areas. This optimizes the contact effect between the air and the probe 2, improving the accuracy of temperature and humidity detection.

[0028] In a preferred embodiment, four baffles 5 are evenly distributed on the probe head 2. These four evenly distributed baffles 5 guide airflow towards the probe head 2 from all directions, creating a uniform and stable airflow environment around it. This uniform distribution helps eliminate detection errors that may be caused by uneven airflow, ensuring full contact between the probe head 2 and the air from all angles, effectively improving the consistency and reliability of temperature and humidity detection results.

[0029] In a preferred embodiment, the magnetic positioning mechanism 8 includes a mounting base, a magnetic element 82, and an elastic buffer assembly. One side of the mounting base is connected to the device body 1 via the elastic buffer assembly, and the other side is provided with the magnetic element 82. The magnetic positioning mechanism 8 is attracted to the iron surface by the magnetic element 82, providing a stable and convenient way to fix the device, facilitating installation and positioning of the device in a suitable location in the warehouse. The addition of the elastic buffer assembly plays a role in buffering and shock absorption, reducing the impact force caused by collisions during installation, protecting the internal electronic components and structural parts of the device, extending the service life of the device, and ensuring the stability of the device during use.

[0030] In a preferred embodiment, the mounting base is an air suction plate 81, and the magnetic component 82 is a strong magnet bonded to the inner surface of the air suction plate 81. The elastic buffer assembly includes a pressure limiting ring 83 and multiple compression springs 84. The pressure limiting ring 83 is fixed to the outer surface of the air suction plate 81, and the multiple compression springs 84 are connected between the pressure limiting ring 83 and the device body 1. The air suction plate 81, as the mounting base, cooperates with the strong magnet to enhance the adsorption force with the iron surface, ensuring that the device is firmly fixed in the mounting position. The elastic buffer assembly composed of the pressure limiting ring 83 and the multiple compression springs 84 can, on the one hand, adjust the force of the device during the adsorption process to avoid damage to the device due to excessive adsorption force; on the other hand, when the device is subjected to external vibration or impact, it can effectively buffer the vibration energy, protect the mechanical structure and electronic components of the device, ensure that its performance is not affected, and maintain the long-term stable operation of the device.

[0031] In a preferred embodiment, the suction plate 81 has a sealing groove 85 on its surface that contacts the iron surface to enhance sealing. The sealing groove 85 enhances the seal between the suction plate 81 and the iron surface, preventing air from entering or leaking from the edge where they contact. This not only further improves the stability of adsorption and fixation but also prevents external impurities such as sand and moisture from entering the device from the edge gaps, protecting the internal structure and electronic components of the device and helping to extend its service life. It also improves the reliability of adsorption and fixation, reducing the possibility of loosening or displacement of the device due to poor sealing.

[0032] In a preferred embodiment, there are four sets of magnetic positioning components, symmetrically arranged on one side of the device body 1. The pressure plate is annular, and each set of magnetic positioning components contains twelve compression springs 84, evenly distributed between the pressure plate and the device body 1. The four symmetrically arranged magnetic positioning components can fix the device body 1 from different positions, making the installation of the device on the iron surface more stable and secure. This avoids problems such as tilting and shaking of the device due to single-point fixing or asymmetrical fixing positions, ensuring that the device remains stable during operation. The annular pressure plate, together with the twelve evenly distributed compression springs 84, further enhances the uniformity of the elastic buffering effect. Regardless of the direction of vibration or impact, the compression springs 84 can evenly disperse and absorb energy, minimizing the impact of vibration on the device, ensuring the stable operation of the internal components, and extending the overall service life of the device.

[0033] In a preferred embodiment, the upper end of the air collection hood 3 has an arc-shaped structure. The air inlet 7 is located at the lower end of the air collection hood 3, and the air outlet is located at the upper end. The arc-shaped structure at the upper end of the air collection hood 3 facilitates smooth airflow and exhaust, reduces air accumulation and turbulence at the top of the air collection hood 3, and improves air circulation efficiency. The layout of the air inlet 7 at the lower end and the air outlet at the upper end conforms to the principle of natural air convection. When the exhaust fan 4 is working, it can form an ideal air convection path, enabling air to smoothly pass through the air collection hood 3 from bottom to top and contact the detector head 2, achieving efficient air exchange, thereby further enhancing the accuracy and reliability of temperature and humidity detection.

[0034] The usage method of this temperature and humidity sampling device is as follows: Installation steps Choose an installation location: Based on the warehouse layout and the area where temperature and humidity need to be monitored, select a suitable flat iron surface as the installation point to ensure that the installation location can well represent the temperature and humidity of the target area and does not hinder normal goods handling and other operations within the warehouse.

[0035] Installation Procedure: Position the device body 1 close to the selected ferrous surface, and the magnetic positioning mechanism 8 will activate. Under the influence of the magnetic field, a powerful magnet firmly adheres the suction plate 81 to the ferrous surface. During this process, the suction plate 81 contacts the ferrous surface, and the sealing groove 85 on the edge surface of the suction plate 81 further enhances the adhesion, sealing, and stability. Simultaneously, the compression spring 84 in the elastic buffer assembly undergoes elastic deformation under pressure, providing cushioning and shock absorption, protecting the device body 1 and internal components from potential impact damage during installation, ensuring stable installation in the designated position.

[0036] Operating steps Activate the forced convection mechanism: Connect the power supply to the device, and the temperature and humidity sampling equipment will begin to work. The exhaust fan 4 installed on the upper part of the air collection hood 3 will start, and the suction generated by the exhaust fan 4 will form a driving airflow. Since the air inlet 7 of the air collection hood 3 is located at the lower end and the air outlet is located at the upper end, the outside air enters the interior of the air collection hood 3 from the air inlet 7 at the lower end of the air collection hood 3 under the action of the suction of the exhaust fan 4, and forms an orderly airflow channel from bottom to top inside the air collection hood 3.

[0037] The air makes full contact with the probe head 2 after passing through the airflow spoiler mechanism: The air entering the air collection hood 3 continues to flow, passing through the turbulence mechanism set around the detector head 2, namely multiple evenly distributed wind deflectors 5 with a conical tubular structure.

[0038] The conical tubular baffle 5 guides air to the surface of the probe head 2, allowing the air to flow more orderly around the probe head 2. Simultaneously, the vents 6 located near the probe head 2 on the baffle 5 increase airflow and the uniformity of contact with the probe head 2 surface. This design prolongs the residence time of air on the probe head 2 surface, enabling the probe head 2 to fully exchange heat and humidity with air at different locations and in different states, thereby collecting more accurate temperature and humidity data from the environment.

[0039] Data Acquisition and Transmission (if applicable): Probe 2 collects temperature and humidity data in the environment in real time (how the collected data is transmitted depends on the matching data transmission module; if there is a wireless transmission module, the data is sent to the receiving end according to the corresponding wireless transmission protocol; if it is wired transmission, the data is transmitted to the corresponding equipment or system according to the established line). The collected data is transmitted to the subsequent processing unit or monitoring center (if applicable) so that warehouse managers can observe and record the temperature and humidity in the warehouse in real time, providing a basis for subsequent judgment on whether the temperature and humidity in the warehouse are suitable for the storage of goods and whether corresponding adjustment measures need to be taken.

[0040] Maintenance and upkeep procedures Regularly check the adsorption status: Regularly check the adsorption status of the magnetic positioning mechanism 8 to ensure that the device body 1 is firmly fixed in the installation position. If any signs of loosening are found, check the contact between the suction plate 81 and the iron surface, check whether there are any foreign objects in the sealing groove 85 that affect the adsorption seal, and check whether the magnetism of the strong magnet block has weakened, etc.

[0041] Cleaning components: Regularly clean components such as the air intake hood 3 and the wind deflector 5 to prevent dust and debris from accumulating and affecting airflow and detection accuracy. Use a soft cleaning tool to wipe their surfaces, ensuring that the air inlet 7, air outlet, and vent 6 are unobstructed.

[0042] System testing: Regularly perform functional tests on the entire temperature and humidity sampling equipment. Turn on the device and check whether the data collected by probe 2 is accurate, whether the forced convection mechanism is operating normally, and whether the coordination between various components is normal. If any abnormalities are found, repair or debugging should be carried out in a timely manner.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
