[0002] Among numerous food safety testing tools, reagent kits have become a common method for rapid screening in laboratories and on-site due to their convenience and specificity. However, the active ingredients in these kits are extremely sensitive to environmental factors such as temperature and humidity. Exposure to air can disrupt the internal chemical balance of the kits, leading to degradation or inactivation, which severely affects the accuracy and reliability of the test results. Therefore, to ensure the stability of the kits, strict airtight storage measures must be taken to isolate them from the adverse effects of the external environment.

[0003] While this sealed storage requirement ensures reagent effectiveness, it also introduces an additional step – manual unpacking. Before testing, personnel must open the sealed packaging and remove the reagent kit. This extra step significantly impacts testing efficiency. In situations requiring the processing of large numbers of samples or urgent testing, the accumulated time spent manually unpacking can become a critical factor limiting testing speed. Furthermore, manual operation increases the risk of human error, such as reagent contamination or damage due to improper packaging removal, further threatening the accuracy of test results.

[0019] In a preferred embodiment, the storage box includes a box body and a top cover, and a first snap-fit ​​structure is provided between the top cover and the box body.

The first cover body and the second cover body are fastened together by the second snap-fit ​​structure to form the top cover.

[0022] Compared with the prior art, the constant temperature and humidity automatic discharging device of this utility model has the following advantages:

[0023] (1) The constant temperature and humidity automatic discharging device of this utility model includes at least a storage box, a discharging mechanism, and a temperature and humidity regulating device connected to the inside of the storage box. The bottom of the storage box is provided with a discharging trough extending from the inside out. The discharging mechanism includes a discharging plate adapted to the discharging trough and a first driving mechanism. The discharging plate is provided with a holding part for placing materials. The discharging plate has a first state where the holding part is inside the storage box and a second state where the holding part is outside the storage box. The output end of the first driving mechanism is connected to the discharging plate and is used to drive the discharging plate to slide relative to the discharging trough, thereby switching the discharging plate between the first and second states. On the one hand, the discharging trough of the storage box and the discharging mechanism work closely together to build an automatic discharging channel for the materials. With the help of this channel, the materials can be output in an orderly manner according to a pre-set method, providing strong support for the automation of the detection process, thereby greatly improving the overall detection efficiency. On the other hand, the matching of the discharge plate and the discharge chute ensures that the material can selectively and smoothly fall one by one during the discharge process. This not only effectively avoids jamming or spillage during discharge, but also guarantees the accuracy and consistency of each discharge, achieving automatic material discharge. By reducing manual intervention, the risks and errors that may be caused by manual operation are reduced, further improving the reliability and stability of the detection.

[0024] The temperature and humidity control device includes at least a ventilation unit for regulating airflow within the storage tank. Regulating airflow helps maintain a stable temperature and humidity environment within the tank, ensuring the performance stability of the test materials (such as reagent kits) and preventing them from being affected by air humidity, thus ensuring the accuracy of test results. The device also includes a temperature control unit for regulating the internal temperature of the storage tank. This unit controls the temperature within the tank according to the temperature requirements of the test materials, keeping them within a suitable storage temperature range. This helps extend the shelf life of the test materials, preventing material failure due to temperature fluctuations, thereby ensuring the smooth progress of testing and the reliability of test results. By ensuring a constant temperature and humidity within the storage tank, test materials, such as reagent kits, can be pre-disassembled and placed inside the tank, preventing them from becoming ineffective due to environmental temperature and humidity fluctuations. This eliminates the need for manual unpacking of the sealed packaging during testing, improving testing efficiency.

[0025] (2) The constant temperature and humidity automatic discharging device of this utility model also includes a turntable located inside the storage box and rotatably connected to the bottom wall of the storage box, and a second drive mechanism. The turntable is provided with at least one material box adapted to the holding section for loading materials along the circumferential direction. This structural design greatly increases the storage method and scheduling flexibility of materials in the storage box. Multiple material boxes can be set on the turntable according to actual testing needs, simultaneously storing different types or batches of testing materials. This facilitates the testing personnel in calling up the required materials at any time according to the testing process, improving the efficiency and convenience of material management. The turntable is provided with openings corresponding to the material boxes, allowing materials to pass through sequentially in a set order. During the testing process, when a specific material needs to be output, the rotation of the turntable accurately aligns the material box containing that material with the discharging slot, achieving orderly material output and avoiding material output chaos, further improving the standardization and accuracy of the testing process.

[0026] The rotary storage design makes full use of the space inside the storage bin, allowing for the storage and distribution of more materials within a limited space through rotation. Compared to traditional static storage methods, rotary storage more effectively utilizes the vertical and horizontal space of the storage bin, improving space utilization and enabling the device to meet greater material storage needs within a smaller volume.

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0041] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0043] This embodiment provides a constant temperature and humidity automatic discharge device, such as... Figure 1 As shown, it includes at least a storage bin 1, a discharge mechanism 2, and a temperature and humidity control device 3 connected to the inside of the storage bin. Figure 3 As shown, the bottom wall of the storage box 1 is provided with a discharge trough 11 extending from the inside to the outside. Figure 5 As shown, the discharge mechanism 2 includes a discharge plate 21 adapted to the discharge trough 11 and a first drive mechanism 22. The discharge plate 21 is provided with a holding part 211 for placing materials. The discharge plate has a first state in which the holding part 211 is located inside the storage box 1, and a second state in which the holding part is located outside the storage box. The output end of the first drive mechanism is connected to the discharge plate and is used to drive the discharge plate 21 to slide relative to the discharge trough 11, thereby switching the discharge plate between the first state and the second state. On the one hand, the discharge trough of the storage box and the discharge mechanism work closely together to build an automatic discharge channel for materials. With the help of this channel, materials can be output in an orderly manner according to a preset method, providing strong support for the automation of the detection process, thereby greatly improving the overall detection efficiency. On the other hand, the adaptation of the discharge plate to the discharge trough ensures that materials can selectively and stably and smoothly fall one by one during the discharge process. This not only effectively prevents material from jamming or spilling during discharge, ensuring the accuracy and consistency of each discharge, but also achieves automated material discharge. By reducing manual intervention, it lowers the risks and errors that may arise from manual operation, further improving the reliability and stability of the detection.

[0044] like Figure 6As shown, the temperature and humidity control device 3 includes at least a ventilation unit 31 for regulating airflow inside the storage tank and a temperature control unit 32 for regulating the temperature inside the storage tank. Regulating airflow through the ventilation unit 31 helps maintain a stable temperature and humidity environment inside the storage tank, ensuring the performance stability of the test materials (such as reagent kits), preventing them from being affected by air humidity, and ensuring the accuracy of test results. The temperature control unit 32 can control the temperature inside the storage tank according to the temperature requirements of the test materials, keeping the materials within a suitable storage temperature range. This helps extend the shelf life of the test materials, avoids material failure due to temperature fluctuations, and thus ensures the smooth progress of testing and the reliability of test results. By ensuring a constant temperature and humidity inside the storage tank through the temperature and humidity control device 3, test materials, such as reagent kits, can be disassembled in advance and placed inside the storage tank, preventing them from failing due to environmental factors such as temperature and humidity. This avoids the need for manual unpacking of the sealed packaging during testing, improving testing efficiency.

[0045] like Figure 1 and Figure 2 As shown, the constant temperature and humidity automatic discharging device of this embodiment also includes a turntable 12 located inside the storage tank 1 and rotatably connected to the bottom wall of the storage tank, and a second drive mechanism 13. Figure 7 As shown, the turntable 12 is provided with at least one material box 121 that is adapted to the holding part 211 for loading materials along the circumferential direction. This structural design greatly increases the storage method and scheduling flexibility of materials in the storage box. Multiple material boxes can be set on the turntable according to actual testing needs to store different types or batches of testing materials at the same time, which makes it convenient for testing personnel to call up the required materials at any time according to the testing process, thus improving the efficiency and convenience of material management.

[0046] The turntable 12 is also equipped with openings 122, one-to-one with the material boxes, for sequentially accommodating materials passing through. This allows materials to pass through the openings in a set order. During the testing process, when a specific material needs to be output, the rotation of the turntable accurately aligns the material box containing that material with the discharge slot, achieving orderly material output and avoiding chaotic material output, further improving the standardization and accuracy of the testing process. The output end of the second drive mechanism 13 is fixedly connected to the turntable, driving the turntable to rotate relative to the bottom wall of the storage bin. The turntable design fully utilizes the space within the storage bin, allowing for the storage and distribution of more materials within a limited space through rotational motion. Compared to traditional static storage methods, turntable storage more effectively utilizes the vertical and horizontal space of the storage bin, improving its space utilization rate and enabling the device to meet greater material storage needs within a smaller volume.

[0047] like Figure 7As shown, in this embodiment, the material box 121 includes a first fixing plate 1211 and a second fixing plate 1212 that are symmetrically distributed radially along the turntable 12. The first fixing plate surrounds the turntable rotation center axis to form an installation cavity 1213. The first fixing plate and the second fixing plate form a space for accommodating the test material, ensuring that the test material is stable during the rotation of the turntable.

[0048] like Figure 1 and Figure 2 As shown, the second drive mechanism 13 includes a second drive element 131, a mounting bracket 132 for mounting the second drive element, and a coupling 133 and a drive shaft 134 sequentially connected to the output end of the second drive element. The coupling 133 protrudes outward to form a positioning part 1331. The second drive mechanism 13 is also equipped with a position sensor 135 adapted to the positioning part, which can detect the rotation position of the turntable in real time, realize precise control of the turntable movement, ensure that the material box accurately reaches the designated position, and improve the stability and reliability of the device operation.

[0049] In this embodiment, the drive shaft 134 passes through the mounting cavity 1213 and is fixedly connected to the turntable.

[0050] like Figure 3 and Figure 6 As shown, the temperature and humidity control device 3 also includes a housing 33 installed at the bottom of the storage box 1, and a ventilation unit 31 and a temperature control unit 32 installed inside the housing, making the overall structure of the temperature and humidity control device more compact, easier to install and maintain, and reducing the space occupied by the temperature and humidity control device.

[0051] The bottom wall of the storage bin is provided with at least one airflow channel 14 that communicates with the interior of the shell, and the output end of the ventilation unit 31 is adapted to the airflow channel 14. In this embodiment, the ventilation unit 31 is a fan, and the fan outlet is arranged opposite to the airflow channel 14. The fan regulates the airflow inside the storage bin 1 through the airflow channel 14, thereby keeping the temperature and humidity inside the storage bin constant and providing a good storage environment for the materials.

[0052] like Figure 7 As shown, the turntable 12 is provided with airflow holes 123 that are compatible with the airflow channel 14. When the turntable rotates, the airflow can be distributed more evenly to each material box position in the storage box through the airflow holes, thereby improving the uniformity of temperature and humidity regulation and ensuring that the materials in different positions in the box are in a suitable temperature and humidity environment.

[0053] like Figure 1As shown, the constant temperature and humidity automatic discharging device of this embodiment also includes a detection device 4. The detection device includes a mounting plate 41 fixedly connected to the storage box 1, and a first sensor 42 installed on the free end of the mounting plate for detecting the state of the material in the holding section. It can detect the state of the material in the holding section in real time, such as whether the material is sufficient and the quality of the material, and provide feedback information for the automated operation of the device, so as to facilitate timely adjustment of the discharging strategy and ensure the continuity and stability of production.

[0054] like Figure 1 and Figure 4 As shown, the storage bin 1 includes a body 15 and a top cover 16. A first snap-fit ​​structure 17 is provided between the top cover and the body, and the top cover and the body are fastened together by the first snap-fit ​​structure to form a constant temperature and humidity storage chamber. On the one hand, the method of fastening the body and the top cover by the first snap-fit ​​structure makes the opening and closing of the top cover simple and convenient, facilitating the cleaning, maintenance, and material addition and removal of the storage bin, thus improving work efficiency. On the other hand, the first snap-fit ​​structure can ensure the sealing between the body and the top cover to a certain extent, which helps to maintain a constant temperature and humidity environment in the storage chamber and reduce the impact of the external environment on the materials.

[0055] like Figure 1 As shown, the constant temperature and humidity automatic discharging device of this embodiment also includes a second sensor 5 installed in the storage box 1 for detecting the internal temperature and humidity of the storage box. The ventilation unit 31 controls the air flow in the storage box based on the data transmitted by the second sensor, and the temperature control unit 32 controls the temperature in the storage box based on the data transmitted by the second sensor. This realizes automatic monitoring and precise control of the temperature and humidity in the storage box, improves the adaptability of the device to the material storage environment, and ensures the stability of material quality.

[0056] like Figure 4 As shown, the top cover 16 includes a first cover body 161 and a second cover body 162 symmetrically distributed. A second snap-fit ​​structure 163 is provided between the first cover body and the second cover body, and the first cover body and the second cover body are snapped together by the second snap-fit ​​structure to form the top cover. On the one hand, this makes the opening of the top cover more flexible, facilitates the maintenance and repair of the internal components (such as ventilation units, temperature control units, etc.) of the top cover, and reduces maintenance costs; on the other hand, it optimizes the top cover structure. This split top cover structure allows for the individual replacement or repair of a part according to actual needs, improving the practicality and maintainability of the device and extending its service life.

[0057] In summary, 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
