Existing soil sample preservation devices primarily focus on the ease of storage and retrieval, such as simplifying operations through push-pull or drawer-style structures.

[0003] For example, a soil sample preservation device with application number CN202423249814.7 and authorization announcement date of 20251128 includes a box body and a storage mechanism disposed on the outer side of the end of the box body. The storage mechanism includes a door, and a storage mechanism for storing samples is provided on one side of the box body. The push-pull design of the storage mechanism allows users to easily pull out or push the placement box into the box body without complicated operations, reducing the difficulty of operation and improving the efficiency of use. Locking and closing the box door is also completed by a simple push-pull action, without the need for additional locks or tools, simplifying the usage process. During the push-pull process, the storage mechanism can ensure a tight fit between the placement box and the box body.

[0004] Traditional soil sample preservation devices lack the function of actively regulating the temperature and humidity of the preservation environment, making it difficult to maintain the stable preservation conditions required for soil samples. Therefore, it is urgent to design a soil sample preservation device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil sample preservation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A soil sample preservation device includes a base and a storage tank. The storage tank is located directly above the base. Four storage slots arranged in a circumferential array are formed on the outer side wall of the storage tank, and a fan-shaped storage area is formed on one side of the inner wall of each storage slot. An embedding slot is formed at one end of the storage tank, and four insertion slots arranged in an array are formed at the bottom of the inner wall of the embedding slot. Several micropores are formed on one side of the inner wall of each fan-shaped storage area. The four embedding slots and the four fan-shaped storage areas are interconnected one-to-one through the micropores. A temperature control component is provided at the top of the storage tank. An installation slot is formed at the other end of the storage tank, and a humidification module, a pumping module, and a control module are bolted to one side of the inner wall of the installation slot. The pumping module is interconnected with the four insertion slots through pipes, and with the humidification module through pipes. A water injection pipe is connected to the humidification module. The control module is electrically connected to the humidification module, the pumping module, and the temperature control component through pipes.

[0007] Furthermore, a connecting seat is mounted at the top center of the base via a bearing, and the top bolt of the connecting seat is mounted on the end of the storage tank with the mounting groove.

[0008] Furthermore, the base has an internal mounting groove, and a rotating handle is mounted inside the mounting groove via a bearing. The rotating handle is fixedly connected to the connecting seat via bolts.

[0009] Furthermore, a door is bolted to one side of the inner wall of the storage tank, and a door handle is bolted to the outer wall of the door.

[0010] Furthermore, three L-shaped grooves with an upper and lower structure are provided on both sides of the inner wall of the fan-shaped storage area, and a tray is slidably inserted into the L-shaped groove. Several insertion holes are provided on one side of the top of the tray.

[0011] Furthermore, the temperature control assembly includes a cover plate bolted to one end of the storage tank with an embedded groove.

[0014] In the above technical solution, the soil sample preservation device provided by this utility model has the following beneficial effects: This invention constructs a complete closed-loop environmental control system by setting up a temperature control component, a humidification module, and a pumping module that are electrically controlled by a unified control module, and by using a micropore and pipeline system to connect each functional module with four sector-shaped storage areas. This design can actively and precisely adjust and maintain the temperature and humidity in each independent sector-shaped storage area according to preset or real-time needs, overcoming the passive preservation defects of traditional devices that rely on the external environment. It can provide suitable and stable preservation conditions for soil samples with different properties, greatly reducing the risk of changes in the physicochemical properties of samples due to environmental fluctuations, and ensuring the accuracy and reliability of subsequent analysis.

[0015] This utility model features a storage tank with four storage slots arranged in a circumferential array and an internal fan-shaped storage area. This design enables independent storage of samples in separate zones, effectively preventing cross-contamination between different samples. Furthermore, the base, through the cooperation of a connecting seat, bearings, and a rotating handle, allows users to easily rotate any storage slot to a convenient operating position without moving the entire device.

The storage tank 5 is located directly above the base 1. Four storage slots 6 arranged in a circumferential array are formed on the outer side wall of each storage tank 5. A fan-shaped storage area 7 is formed on one side of the inner wall of each storage slot 6. An embedding slot 15 is formed at one end of the storage tank 5. Four insertion slots 16 arranged in an array are formed at the bottom of the inner wall of the embedding slot 15. A plurality of micropores 14 are formed on one side of the inner wall of each fan-shaped storage area 7. The four embedding slots 15 are paired with the four fan-shaped storage areas 7 one-to-one. The storage tank 5 is interconnected through micropores 14. A temperature control component 10 is provided on the top of the storage tank 5. An installation groove 21 is provided at the other end of the storage tank 5. A humidification module 22, an extraction module 24 and a control module 23 are bolted to one side of the inner wall of the installation groove 21. The extraction module 24 is interconnected with the four insertion grooves 16 through pipes. The extraction module 24 is interconnected with the humidification module 22 through pipes. A water injection pipe is connected to the outside of the humidification module 22. The control module 23 is electrically connected to the humidification module 22, the extraction module 24 and the temperature control component 10 through pipes.

[0025] Specifically, in this embodiment, the system includes a base 1 and a storage tank 5. The storage tank 5 is located directly above the base 1. Four storage slots 6 arranged in a circumferential array are formed on the outer side wall of the storage tank 5. A fan-shaped storage area 7 is formed on one side of the inner wall of each storage slot 6. An embedding slot 15 is formed at one end of the storage tank 5. The embedding slot 15 accommodates the connector module 18 and the heat-conducting plate 20 of the temperature-regulating component 10, and provides a buffer and mixing chamber for airflow. Four insertion slots 16 arranged in an array are formed at the bottom of the inner wall of the embedding slot 15. The insertion slots 16 tightly accommodate the heat-conducting plate 20 to ensure efficient heat conduction, and also serve as an airflow channel interface connecting the extraction module 24 pipe to the embedding slot 15. Several micropores 14 are formed on one side of the inner wall of the fan-shaped storage area 7. The micro-channels 14 connect the embedded slots 15 and the fan-shaped storage areas 7. Their core function is to allow temperature- and humidity-controlled air or inert gas to diffuse evenly and slowly into each storage compartment, while preventing the sample from being directly impacted by strong airflow. The four embedded slots 15 and four fan-shaped storage areas 7 are interconnected one-to-one via the micro-channels 14. A temperature control component 10 is located on the top of the storage tank 5. This component is the entire temperature control assembly, integrated and sealed at one end of the storage tank 5 via a cover plate 17. It is responsible for providing heat to the storage areas as instructed to maintain a constant temperature. An installation slot 21 is located at the other end of the storage tank 5. A humidification module 22, a delivery module 24, and a control module 23 are bolted to one side of the inner wall of the installation slot 21. Module 22 is used to generate and control the humidity of the air delivered to the storage area. It may include core components such as an ultrasonic atomizer, a wet film evaporator, or a steam generator. The model selected is an ultrasonic atomizing module commonly used in laboratory equipment, integrating a water level sensor and a fan, requiring an external water supply pipe or an internal water tank. Control module 23 is a control circuit board integrating a microprocessor (MCU). It is responsible for receiving user settings or sensor feedback, such as a temperature and humidity sensor (not shown in the diagram but should be present), and outputting control signals to the temperature control component 10, the humidification module 22, and the extraction module 24 to maintain environmental parameters within the set range. The model uses a small control board based on STM32, Arduino, or PLC, paired with a temperature and humidity sensor such as SHT30, a relay, or... The solid-state relay (SSR) output circuit integrates a touchscreen or buttons for human-machine interaction. The extraction module 24 provides the power for air circulation and is a miniature air pump or fan system responsible for forcibly delivering temperature- and humidity-controlled air from the humidification module 22 / embedded slot 15 area to each storage area through pipes. It may also extract internal air to form circulation or ventilation. The model selected is a low-noise, long-life miniature diaphragm pump or brushless DC fan assembly. The extraction module 24 is interconnected with the four insertion slots 16 through pipes. The extraction module 24 is interconnected with the humidification module 22 through pipes. The humidification module 22 is externally connected to a water injection pipe. The control module 23 is electrically connected to the humidification module 22, the extraction module 24, and the temperature control component 10 through pipes.

[0026] This invention provides a soil sample preservation device. By setting up a temperature control component 10, a humidification module 22, and a pumping module 24, all electrically controlled by a control module 23, and utilizing micropores 14 and a pipeline system to connect each functional module with four sector-shaped storage areas 7, a complete closed-loop environmental control system is constructed. This design can actively and precisely adjust and maintain the temperature and humidity in each independent sector-shaped storage area 7 according to preset or real-time needs. It overcomes the passive preservation defects of traditional devices that rely on the external environment, and can provide suitable and stable preservation conditions for soil samples of different properties. This greatly reduces the risk of changes in the physicochemical properties of the samples due to environmental fluctuations, and ensures the accuracy and reliability of subsequent analysis.

[0027] In one embodiment provided by this utility model, such as Figure 1-2 As shown, a connecting seat 4 is mounted on the top center of the base 1 via a bearing. The connecting seat 4 connects the drive shaft of the rotating handle 3 to the storage tank 5. A bolt is bolted to the top of the connecting seat 4 and installed on the end of the storage tank 5 with the mounting groove 21. The base 1 has a mounting groove 2 inside, and the rotating handle 3 is mounted inside the mounting groove 2 via a bearing. The rotating handle 3 provides a manual operation interface for the user. By rotating the rotating handle 3, the connecting seat 4 and the entire storage tank 5 can be rotated, thereby turning the different storage slots 6 toward the user for convenient access. The rotating handle 3 is fixedly connected to the connecting seat 4 via bolts.

[0028] In another embodiment provided by this utility model, such as Figure 1-4 As shown, a door 11 is bolted to one side of the inner wall of the storage tank 6, and a door handle 12 is bolted to the outer wall of the door 11. The door handle 12 provides the user with a force point to open and close the door 11. Three L-shaped grooves 13 with an upper and lower structure are opened on both sides of the inner wall of the fan-shaped storage area 7. The L-shaped grooves 13 are guide grooves on both sides of the fan-shaped storage area 7, used to support and guide the horizontal insertion and removal of the tray 8, so as to realize the detachable and layered positioning of the tray 8. The tray 8 is slidably inserted into the L-shaped groove 13. The tray 8 can be inserted into the L-shaped groove 13 of the fan-shaped storage area 7. The insertion hole 9 opened on it is used to fix the sample tube or container, so as to realize the orderly storage and layered management of the sample. Several insertion holes 9 are opened on one side of the top of the tray 8. The insertion holes 9 are located on the tray 8 and are used to insert and fix the test tube, glass bottle or small container containing soil sample, so as to prevent it from tipping over or colliding during transportation or rotation.

[0029] In another embodiment provided by this utility model, such as Figure 5As shown, the temperature control assembly 10 includes a cover plate 17, which is bolted to one end of the storage tank 5 with an embedded groove 15. Four connector modules 18 are bolted to the bottom of the cover plate 17. Each connector module 18 integrates an electrical connection interface, serving as both a source for external power and control signals to the constant-temperature heating element 19 and a mechanical support. The connectors use standard multi-core waterproof aviation connectors, such as a combination of a GX series aviation connector and a custom mounting plate. All four connector modules 18 are located inside the embedded groove 15. A constant-temperature heating element 19 is bolted to one side of the bottom of each connector module 18. The constant-temperature heating element 19 is the temperature control actuator, converting electrical energy into heat according to the instructions of the control module 23. Yes, it typically has self-limiting temperature characteristics, such as PTC heating elements or works in conjunction with a temperature controller to prevent overheating. The model uses flexible silicone heating elements, and the power needs to be calculated based on the heat load of the storage tank 5. The bottom end of the constant temperature heating element 19 is welded with a heat-conducting plate 20, which is a highly efficient heat conduction component. It is welded or tightly attached to the constant temperature heating element 19, and quickly transfers the heat from the point / area heat source to the entire metal wall of the insertion slot 16 into which it is inserted. Then, it is homogenized by air convection to avoid local high temperatures. It uses a material with a high thermal conductivity, such as aluminum or copper sheet, for example, 6063 aluminum alloy plate, and the surface can be treated with anti-oxidation. The structure composed of the constant temperature heating element 19 and the heat-conducting plate 20 is inserted into the structure composed of the embedding slot 15 and the insertion slot 16.

[0030] Working principle: When storing samples, open the door 11 and insert the test tube or container carrying the sample into the insertion hole 9 on the tray 8. The tray 8 slides into the fan-shaped storage area 7 through the L-shaped groove 13, forming a stable and flexibly adjustable layered storage structure. The four independent fan-shaped storage areas 7 achieve physical isolation of the samples, effectively preventing cross-contamination. After the device stores the samples, the control module 23 operates according to preset temperature and humidity parameters or received external commands. When it is necessary to increase the humidity inside the storage tank 5, the control module 23 starts the humidification module 22. The humidification module 22 delivers the water vapor generated inside or through the external water injection pipe to the connected pipe. At the same time, the control module 23 starts the pumping module 24. The pumping module 24 acts as a power source, generating airflow and pumping the humid air output by the humidification module 22 through the pipe to the four insertion slots 16 respectively. The air then enters the cavity of the insertion slot 15 through the insertion slot 16, and further diffuses evenly and gently into the four corresponding sector-shaped storage areas 7 through the micropores 14 that communicate with it. This design ensures that each independent storage area can obtain uniform humidity regulation. When the humidity is too high and dehumidification or air circulation is required, the extraction module 24 can work in reverse to extract the humid air in the storage area, bypass or process it through the humidification module 22, and then discharge or recirculate it, thereby achieving precise humidity control. Temperature control is mainly performed by the temperature control component 10. When it is necessary to raise the temperature or maintain a constant temperature, the control module 23 sends a command to the temperature control component 10. The constant temperature heating element 19 starts to work and generates heat, which is efficiently conducted through the heat-conducting element 20 welded to it. The heat-conducting element 20 is directly inserted deep into the insertion slot 16, and its heat is first transferred to the air in the insertion slot 16 and the insertion slot 15. Subsequently, the heated air also circulates into each sector-shaped storage area 7 through the aforementioned micropore network 14 to gently heat the sample. The direct insertion design of the heat-conducting plate 20 greatly improves heat conduction efficiency, while the micropore system 14 ensures uniform heat distribution within the container, preventing localized overheating. When retrieving samples from specific zones, the user can operate the rotating handle 3 located within the base 1. The rotating handle 3 drives the entire storage container 5 to rotate around the bearing via the connecting seat 4. Because the storage slots 6 of the storage container 5 are arranged in a circumferential array, the user can easily rotate the target storage slot 6 to the optimal operating position directly in front, without moving the entire device or laboriously searching for it, greatly improving retrieval efficiency.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
