Description

Technical Field

[0001] This utility model relates to the field of tobacco storage equipment technology, and in particular to a tobacco sample rack with a dry-keeping function. Background Technology

[0002] As a crop with significant economic value, the stability and consistency of tobacco quality are crucial for the development of the tobacco industry. Proper storage of tobacco samples is essential in all stages of tobacco research and development, production, quality testing, and marketing. Accurate sample storage not only preserves the original characteristics of the tobacco, providing a reliable basis for subsequent research and analysis, but also ensures that tobacco quality can be compared and evaluated at different points in time, thereby guaranteeing product quality stability.

[0003] Currently, common methods for storing tobacco samples often employ ordinary sealed boxes or simple sample racks, which have significantly insufficient drying capabilities. These methods often rely on natural drying or static sealing of the environment, and cannot actively and continuously absorb moisture from the sample's own respiration or from external seepage. When the ambient humidity fluctuates, a saturated humid environment easily forms inside the sample box, resulting in a passive and extremely limited drying effect, and failing to effectively maintain the low humidity constant state required for the sample. Utility Model Content

[0004] The purpose of this invention is to propose a tobacco sample rack with a drying function to solve the problem that existing tobacco sample racks lack an effective drying function.

[0005] To achieve the above objectives, this utility model provides a tobacco sample rack with a drying function, comprising: a sample rack body and a desiccant compartment; A drying assembly is installed on one side of the desiccant compartment of the sample rack body, and the drying assembly is used to place tobacco and keep it dry; A limiting component is installed on both sides of the drying component, and the limiting component is used to install the drying component.

[0006] Preferably, the drying assembly includes several mounting plate desiccant compartments installed on the desiccant compartment of the sample rack body. The mounting plate desiccant compartments are connected to the desiccant compartment of the sample rack body by rivets. The mounting plate desiccant compartments have several mounting slot desiccant compartments and keyhole desiccant compartments. A display box desiccant compartment is installed in the mounting slot desiccant compartment. The display box desiccant compartment is used to hold tobacco. A sealing cover desiccant compartment is connected to one side of the display box desiccant compartment by a sealing buckle. A mounting frame desiccant compartment is fixedly installed on the side of the display box desiccant compartment away from the sealing cover desiccant compartment. A desiccant compartment is slidably installed in the mounting frame desiccant compartment. The desiccant compartment is used to hold desiccant.

[0007] Preferably, the mounting plate desiccant compartment has a vent desiccant compartment, which is disposed through the mounting plate desiccant compartment. Each mounting slot desiccant compartment has a lock hole desiccant compartment on both sides symmetrically, and the mounting slot desiccant compartment is disposed through the vent desiccant compartment.

[0008] Preferably, a moisture-permeable desiccant compartment is fixedly installed on the side of the desiccant compartment away from the desiccant compartment of the sealing cover. Several moisture-absorbing channels are provided on the side of the desiccant compartment away from the desiccant compartment of the display box. Several ventilation openings are provided on both sides of the desiccant compartment. The desiccant compartment is at the same height as the ventilation opening desiccant compartment. The desiccant compartment and the desiccant compartment of the display box are connected by snap-fit. A grooved desiccant compartment is provided on one side of the desiccant compartment.

[0009] Preferably, the limiting component includes connecting block desiccant compartments symmetrically and fixedly installed on both sides of the desiccant compartment of the display box, a connecting column desiccant compartment slidably installed inside the connecting block desiccant compartment, a handle desiccant compartment rotatably installed on one side of the connecting column desiccant compartment, and a lock head desiccant compartment fixedly installed on the side of the connecting column desiccant compartment away from the handle desiccant compartment, the lock head desiccant compartment being compatible with the lock hole desiccant compartment.

[0010] Preferably, the desiccant compartment of the connecting block has a through-hole desiccant compartment, and a limit ring desiccant compartment is fixedly installed on the side of the through-hole desiccant compartment near the desiccant compartment of the handle. The desiccant compartment of the connecting column is slidably installed in the limit ring desiccant compartment and the through-hole desiccant compartment in sequence.

[0011] Preferably, a pressure spring desiccant chamber is fitted onto the desiccant chamber of the connecting column. The pressure spring desiccant chamber is installed inside the through-hole desiccant chamber. One side of the pressure spring desiccant chamber is fixedly installed on one side of the limiting ring desiccant chamber, and the other side of the pressure spring desiccant chamber is fixedly installed on one side of the lock head desiccant chamber.

[0012] The beneficial effects of this utility model are: 1. This tobacco sample rack with a drying function achieves airtight storage and efficient drying of tobacco samples by setting up drying components, including a mounting plate, display box, sealing cover, moisture-permeable partition, and desiccant chamber. The display box is used to place tobacco samples, and the sealing cover forms a stable and airtight space through sealing buckles to prevent external moisture from entering. The desiccant chamber contains desiccant, and air circulation paths are formed through moisture absorption channels, ventilation openings, and vents to achieve rapid moisture removal and absorption. The moisture-permeable partition allows moisture to pass through but blocks impurities from entering, further maintaining a clean and stable internal environment. The cooperation of these structural spaces effectively prevents tobacco samples from becoming moldy or deteriorating due to moisture during storage, improves the stability and quality of tobacco sample storage, extends the sample preservation period, and has good practicality.

[0013] 2. This tobacco sample rack with a dry-keeping function achieves rapid locking and stable positioning of the display box and mounting plate by setting a limiting component, including a connecting block, connecting column, lock head, handle, and pressure spring. During installation, the operator only needs to push the handle to make the lock head engage in the lock hole for positioning. After release, the pressure spring automatically resets, ensuring that the lock head remains in the locked state. During disassembly, a light pull on the handle releases the limiting function, and the display box can be quickly removed, avoiding the cumbersome disassembly and assembly problems of traditional limiting methods, and improving the stability and loading / unloading efficiency of the drying component.

[0016] 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 specific embodiments.

[0017] like Figures 1 to 4 As shown, a tobacco sample holder with a drying function includes: a sample holder body 1; a drying component, which is installed on one side of the sample holder body 1 and is used to place tobacco and keep it dry; and a limiting component, which is installed on both sides of the drying component and is used to install the drying component. In use, this device places tobacco samples inside the drying assembly, which utilizes its ventilation and moisture-absorbing structure to continuously dry the tobacco, effectively preventing it from becoming damp and deteriorating. The drying assembly is fixedly installed on one side of the sample holder body 1. During the drying process, the drying assembly and the sample holder body 1 form a stable support structure, ensuring that the tobacco does not tip over or shift during drying. Limiting components are respectively located on both sides of the drying assembly. When the drying assembly is subjected to external force or experiences slight movement during handling, the limiting components limit and guide it, ensuring that the drying assembly always remains in the set position and preventing displacement during the drying process. Through the coordinated use of the sample holder body 1, the drying assembly, and the limiting components, stable support, effective drying, and reliable limiting of the tobacco sample are achieved, ensuring the continuity and stability of the drying process and improving the preservation quality of the tobacco sample.

[0018] like Figure 2 , Figure 3 , Figure 4 As shown, the drying assembly includes several mounting plates 2 installed on the sample holder body 1. The mounting plates 2 are connected to the sample holder body 1 by rivets. Several mounting slots 5 and locking holes 6 are provided on the mounting plates 2. Display boxes 8 are installed in the mounting slots 5. The display boxes 8 are used to hold tobacco. A sealing cover 7 is connected to one side of the display box 8 by a sealing buckle. A mounting frame 11 is fixedly installed on the side of the display box 8 away from the sealing cover 7. A desiccant chamber 9 is slidably installed in the mounting frame 11. The desiccant chamber 9 is used to hold desiccant. The mounting plates 2 have openings for... Air vent 3 is set through the mounting plate 2. Each mounting groove 5 has a lock hole 6 on both sides of the symmetrical arrangement. The mounting groove 5 is set through the air vent 3. A moisture-permeable partition 14 is fixedly installed on the side of the display box 8 away from the sealing cover 7. Several moisture absorption channels 12 are opened on the side of the desiccant chamber 9 away from the display box 8. Several ventilation openings 13 are opened on both sides of the desiccant chamber 9. The desiccant chamber 9 is at the same height as the air vent 3. The desiccant chamber 9 and the display box 8 are connected by a buckle. A groove 10 is opened on one side of the desiccant chamber 9. When the drying assembly is in operation, the tobacco sample is first placed inside the display box 8, and the sealing cover 7 is reliably connected to the display box 8 via a sealing buckle, forming a relatively sealed storage space. A moisture-permeable partition 14, installed on the side of the display box 8 away from the sealing cover 7, allows moisture to pass through but prevents impurities from entering, ensuring a clean internal environment. The desiccant chamber 9 is slidably installed inside the mounting frame 11. The desiccant chamber 9 contains desiccant, which convects with the air inside the display box 8 through the moisture absorption channel 12 and the ventilation opening 13. When the moisture in the tobacco sample evaporates, the moisture enters the desiccant chamber 9 through the moisture-permeable partition 14 and is then dried. The desiccant is absorbed, thus achieving continuous drying of the tobacco sample; the desiccant chamber 9 and the ventilation opening 3 on the mounting plate 2 are set at the same height, allowing external air to enter or exit through the ventilation opening 3, maintaining internal air circulation, and further improving drying efficiency; the display box 8 and the desiccant chamber 9 are connected by a snap-fit ​​structure to achieve quick assembly and disassembly, facilitating the replacement or maintenance of the desiccant; the groove 10 on one side of the desiccant chamber 9 facilitates manual operation, enabling convenient extraction and installation of the desiccant chamber 9, thus forming a closed storage, moisture-permeable drying, air-circulating and maintainable drying system, effectively keeping the tobacco sample in a dry state.

[0019] like Figure 2 , Figure 3 , Figure 4 As shown, the limiting assembly includes connecting blocks 15 symmetrically fixedly installed on both sides of the display box 8. A connecting post 17 is slidably installed in the connecting block 15. A handle 16 is rotatably installed on one side of the connecting post 17. A lock head 18 is fixedly installed on the side of the connecting post 17 away from the handle 16. The lock head 18 is adapted to the lock hole 6. A through hole 21 is opened in the connecting block 15. A limiting ring 19 is fixedly installed on the side of the through hole 21 near the handle 16. The connecting post 17 is slidably installed in the limiting ring 19 and the through hole 21 in sequence. A pressure spring 20 is sleeved on the connecting post 17. The pressure spring 20 is installed in the through hole 21. One side of the pressure spring 20 is fixedly installed on one side of the limiting ring 19, and the other side of the pressure spring 20 is fixedly installed on one side of the lock head 18. When the limiting assembly is in operation, the connecting blocks 15 are symmetrically fixed on both sides of the display box 8, and the connecting post 17 can slide between the through hole 21 in the connecting block 15 and the limiting ring 19. When it is necessary to limit and fix the display box 8, the operator pushes the connecting post 17 inward through the handle 16, so that the locking head 18 at the end of the connecting post 17 away from the handle 16 is inserted into the locking hole 6 on the mounting plate 2, thereby achieving the positioning and locking of the display box 8 and the mounting plate 2; the pressure spring 20 is sleeved on the connecting post 17 and installed. Inside the through hole 21, one end of the pressure spring 20 is fixed to the limiting ring 19, and the other end is fixed to the lock head 18. When the handle 16 is released, the pressure spring 20, under the action of elastic restoring force, automatically pushes the connecting post 17 outward, keeping the lock head 18 stably inserted into the lock hole 6, preventing the display box 8 from loosening or shifting. When it is necessary to disassemble the display box 8, the operator pulls the handle 16 inward, causing the connecting post 17 to slide in the opposite direction, so that the lock head 18 disengages from the lock hole 6, thereby releasing the limiting force. The display box 8 is designed for quick assembly and disassembly. This structure, through the cooperation of the lock head 18, lock hole 6, and pressure spring 20, achieves stable positioning and automatic reset between the display box 8 and the mounting plate 2, ensuring the stability of the display box 8 during the drying process and the convenience of operation. In this embodiment, the display box 8 is made of transparent acrylic material with a thickness of 2mm. The moisture-permeable partition 14 is made of polytetrafluoroethylene microporous membrane with an average pore size of 0.5μm and a moisture permeability of 2000g / m² / 24h. The desiccant chamber 9 is filled with 50g of silica gel desiccant particles with a particle size of 1–3mm, and is installed inside the mounting plate 2 via a slidable embedding structure. When the tobacco sample is placed in the display box 8 and the sealing cover 7 is closed, the moisture in the cavity diffuses into the desiccant chamber 9 through the moisture-permeable partition 14. After the desiccant absorbs moisture, the relative humidity inside the cavity drops from 80% to below 40%, and can remain stable for 24 hours. By periodically replacing the contents of the desiccant chamber 9, a long-term moisture-proof effect can be maintained. In a preferred embodiment, the desiccant compartment 9 and the ventilation opening 3 on the mounting plate 2 are arranged at the same height. This consistent height structure allows for unobstructed airflow paths inside and outside the sample holder body. Under the action of natural airflow or externally driven airflow, external air can enter or exit the cavity of the display box 8 through the ventilation opening 3, exchanging with the internal humid air and thus maintaining continuous internal air convection circulation. To further enhance the airflow velocity, a miniature blower (or low-power blower) can be added outside the ventilation opening 3. This blower is driven by a DC power supply and delivers low-speed airflow evenly into the cavity of the display box 8 through a guide tube. After being diffused through the moisture-permeable baffle 14, the air is discharged through the vent 3 set at the same height, forming a "directional circulating air path". Through this air circulation system, the moisture can be quickly diffused and adsorbed on the surface of the desiccant chamber 9, avoiding local condensation or moisture retention. In addition, the equal height setting of the vent 3 and the desiccant chamber 9 can avoid the formation of a humidity gradient of "dry on top and wet on the bottom" or "dry on the bottom and wet on top", which significantly improves the drying uniformity of the samples in the display box 8. Even under conditions of large fluctuations in ambient humidity, this embodiment can still maintain the humidity in the sample storage chamber within a stable range of 40±5%, improving the reliability of long-term storage of tobacco samples.
