Description

Technical Field

[0001] This utility model relates to the field of tobacco storage device technology, and in particular to a portable tobacco storage box. Background Technology

[0002] In modern society, the demand for portable and convenient tobacco products is gradually increasing, especially for smokers who frequently travel or engage in outdoor activities. Maintaining the freshness and dryness of tobacco during transport has become a pressing issue. Tobacco itself is highly hygroscopic; once exposed to humid air, it easily absorbs moisture, leading to increased water content. This causes the tobacco to soften, burn incompletely, and lose its flavor, even becoming moldy and spoiled. This not only severely impacts the smoking experience but also results in tobacco waste. While some simple tobacco storage boxes have appeared on the market, most only offer basic sealing and lack active moisture-proofing and environmental regulation capabilities, offering limited moisture protection and making it difficult to keep tobacco dry in high-humidity environments for extended periods.

[0003] In addition, some existing moisture-proof tobacco storage devices have relatively simple structures, mostly relying on placing desiccants inside the box to achieve dehumidification. However, due to poor airflow inside the box, moisture is difficult to dissipate in time, easily forming damp areas in corners, resulting in uneven moisture protection and making it difficult to avoid tobacco getting damp. Furthermore, some have complex structures and are inconvenient to disassemble and assemble, making it difficult for users to replace moisture-proof materials or clean the inside, affecting their long-term use. At the same time, during portable transportation, the internal moisture-proof components are prone to loosening and displacement, reducing the overall moisture-proof performance and also posing certain safety hazards. Utility Model Content

[0004] The purpose of this invention is to propose a portable tobacco storage box to solve the problems of low moisture-proof efficiency, poor airflow circulation, and insufficient structural stability of existing tobacco storage boxes.

[0005] To achieve the above objectives, this utility model provides a portable tobacco storage box, comprising: an outer shell, a tobacco storage housing installed inside the outer shell, and a plurality of connecting plates fixedly installed on the symmetrical sides of the tobacco storage housing, the connecting plates being connected to one side of the outer shell by rivets; A moisture-proof component is installed inside the housing and is used to prevent tobacco stored inside the housing from getting damp; A locking component, installed inside the housing, is used to lock the moisture-proof component.

[0006] Preferably, the moisture-proof component includes a moisture-proof box that is slidably installed inside the outer shell. Moisture-proof nets are installed on both sides of the long side and the top surface of the moisture-proof box. The moisture-proof nets are used to promote air circulation.

[0007] Preferably, a plurality of flow-guiding ribs are fixedly installed on the inner walls of both sides of the long side of the outer shell. The flow-guiding ribs are vertically arranged close to the inner walls of the left and right sides of the outer shell and are equal in height to the outer shell. A gap is left between the flow-guiding ribs and the outer side wall of the tobacco storage shell.

[0008] Preferably, the locking assembly includes a fixed base fixedly installed inside the housing, a sliding strip slidably installed on one side of the fixed base, a plurality of mating grooves being formed on the sliding strip, and a plurality of lock heads fixedly installed on the side of the moisture-proof box away from the handle, the lock heads having lock grooves that are adapted to the mating grooves.

[0009] Preferably, a first limiting plate is fixedly installed on one side of the fixed base, and a plurality of return springs are fixedly installed between the sliding bar and the first limiting plate.

[0010] Preferably, two second limiting plates are fixedly installed on the side of the fixed base away from the first limiting plate. A trigger frame and a mating rib are slidably installed between the two second limiting plates. A receiving cavity is opened in the middle of the trigger frame. A guide strip is fixedly installed on one side of the receiving cavity. A through hole is opened on the second limiting plate. The mating rib is slidably installed in the through hole. A sliding groove is opened on the mating rib. The sliding groove is adapted to the guide strip.

[0011] Preferably, a plurality of pressure springs are fixedly installed between the trigger frame and the fixed base.

[0012] The beneficial effects of this utility model are: 1.

[0017] 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.

[0018] like Figures 1 to 6 As shown, a portable tobacco storage box includes: an outer shell 1, a tobacco storage housing 6 installed inside the outer shell 1, and several connecting plates 7 fixedly installed on the symmetrical sides of the tobacco storage housing 6, the connecting plates 7 being connected to one side of the outer shell 1 by rivets; a moisture-proof component installed inside the outer shell 1, the moisture-proof component being used to prevent the tobacco stored inside the outer shell 1 from getting damp; and a locking component installed inside the outer shell 1, the locking component being used to lock the moisture-proof component. This portable tobacco storage box, when in use, forms a completely sealed storage space through the outer shell 1. The tobacco storage shell 6 is used to centrally place tobacco. Several connecting plates 7 arranged on its symmetrical sides are fixedly connected to the outer shell 1 by rivets, thereby enhancing the stability between the tobacco storage shell 6 and the outer shell 1 and preventing the shell from shaking or falling off during carrying or moving. The moisture-proof component is set inside the outer shell 1, which regulates the air humidity in the storage cavity by absorbing moisture and isolating external moisture, effectively preventing the tobacco from getting damp and deteriorating, and ensuring the dryness of the tobacco. The locking component is also installed inside the outer shell 1. Through the locking structure, it cooperates with the moisture-proof component to achieve stable fixation of the moisture-proof component, preventing it from loosening or shifting during carrying, thereby ensuring the long-term effectiveness of the moisture-proof function. The whole device realizes the synergistic working principle of sealed storage of tobacco, moisture protection, and stable locking of the internal structure. To further improve the sealing performance, a silicone sealing ring or rubber sealing strip can be set at the opening of the outer shell 1 of this invention to ensure the airtightness of the internal space in the closed state and prevent external moisture from seeping in, thereby achieving a better moisture-proof effect in conjunction with the moisture-proof component.

[0019] like Figure 2 , Figure 3 , Figure 4 As shown, the moisture-proof component includes a moisture-proof box 2 that is slidably installed inside the outer shell 1. Moisture-proof nets 8 are installed on both sides of the long side and the top surface of the moisture-proof box 2. The moisture-proof nets 8 are used to promote air circulation. A storage slot 3 is opened on one side of the moisture-proof box 2. A pull handle 4 is rotatably installed in the storage slot 3. Several guide ribs 5 are fixedly installed on the inner walls of both sides of the long side of the outer shell 1. The guide ribs 5 are set vertically close to the inner walls of the left and right sides of the outer shell 1 and are equal in height to the outer shell 1. A gap is left between the guide ribs 5 and the outer side wall of the tobacco storage shell 6. In operation, the moisture-proof component of this utility model contains a desiccant in the moisture-proof box 2. The sliding installation of the moisture-proof box 2 allows it to be flexibly placed inside the outer shell 1, facilitating the replacement and maintenance of the moisture-proof material. Moisture-proof mesh 8 installed on both sides and the top of the moisture-proof box 2 ensures that the internal moisture-proof material does not leak out while promoting free air circulation. This allows moisture to be absorbed by the moisture-proof material as it enters the box, thereby reducing the overall humidity inside the outer shell 1 and effectively keeping the tobacco dry. A rotating handle 4 is installed in the storage slot 3 on one side of the moisture-proof box 2, facilitating easy pulling and pushing in / out when replacing or cleaning the moisture-proof box 2, improving the ease of use of the moisture-proof component. A gap is left between the guide ribs 5 fixedly installed on the inner walls of both sides of the long side of the outer shell 1 and the outer side wall of the tobacco storage shell 6, with the guide ribs 5 closely attached to the outer shell 1. The inner wall of the outer shell 1 extends from the bottom to near the opening of the lid, perpendicular to the bottom of the box, and has a right-angled triangular cross-section. In addition, the cross-section of the guide rib 5 can also be a streamlined protrusion, with one side of its right angle fixed to the inner wall of the outer shell 1, and the other side facing the inside of the box. The inclined side forms a guide slope that guides the airflow from bottom to top. When the moisture-proof material in the bottom moisture-proof box absorbs moisture, the airflow on both sides of the guide rib forms a natural upward trend along the guide slope, promoting the uniformity of the internal airflow circulation, avoiding moisture retention, and forming a three-dimensional circulating air channel from the bottom to the top of the box. The guide rib 5 effectively regulates the airflow direction, avoids airflow disturbance and moisture retention, and ensures that the moisture-proof air flows evenly throughout the entire storage space, thereby achieving a fast and efficient dehumidification and moisture-proof effect, and significantly improving the dryness stability of the tobacco storage environment.

[0020] like Figure 3 , Figure 5 , Figure 6 As shown, the locking assembly includes a fixed base 12 fixedly installed inside the housing 1. A sliding strip 13 is slidably installed on one side of the fixed base 12, and several mating grooves 14 are formed on the sliding strip 13. Several lock heads 9 are fixedly installed on the side of the moisture-proof box 2 away from the handle 4, and lock grooves 10 are formed on the lock heads 9, which are adapted to the mating grooves 14. A first limiting plate 16 is fixedly installed on one side of the fixed base 12, and several return springs 15 are fixedly installed between the sliding strip 13 and the first limiting plate 16. The side of the fixed base 12 away from the first limiting plate 16 has several lock heads 9. Two second limiting plates 23 are fixedly installed on one side of plate 16. A trigger frame 17 and a mating rib 21 are slidably installed between the two second limiting plates 23. A receiving cavity 18 is opened in the middle of the trigger frame 17. A guide strip 19 is fixedly installed on one side of the receiving cavity 18. A through hole 24 is opened on the second limiting plate 23. The mating rib 21 is slidably installed in the through hole 24. A sliding groove 22 is opened on the mating rib 21. The sliding groove 22 is adapted to the guide strip 19. Several pressure springs 20 are fixedly installed between the trigger frame 17 and the fixed seat 12. When the locking assembly of this utility model is in operation, the fixed base 12, which is fixedly installed inside the outer shell 1, serves as a support base, ensuring the stability of the overall locking mechanism. The sliding bar 13 reciprocates along the slide rail direction of the fixed base 12. Multiple mating grooves 14 on the sliding bar 13 are adapted to the locking grooves 10 on the lock head 9 fixedly installed on the side of the moisture-proof box 2 away from the handle 4. When the moisture-proof box 2 is pushed into the predetermined position of the outer shell 1, the lock head 9 automatically engages in the mating grooves 14, achieving locking and positioning of the moisture-proof box 2 and the outer shell 1. The sliding bar 13 and the fixed base 12 are connected by a first limiting plate 16 and several return springs 15. After the lock head 9 is inserted into the mating groove 14, the return springs 15 provide elasticity to automatically reset the sliding bar 13, thereby ensuring the stability of the locking state and preventing the moisture-proof box 2 from loosening or falling off during transportation or shaking. During unlocking, the sliding bar 13 is reciprocated by the fixed base 12. Two second limiting plates 23 on the side of the seat 12 away from the first limiting plate 16, the trigger frame 17 and the mating rib 21 work together. The trigger frame 17 has a receiving cavity 18 in the middle, and the guide strip 19 on its side is inserted into the sliding groove 22 on the mating rib 21. When sliding, it forms a stable guide, so that the thrust of the trigger frame 17 is accurately transmitted to the sliding strip 13. When an external force is applied to press the trigger frame 17, the trigger frame 17 slides inward against the elastic force of the pressure spring 20, which drives the mating rib 21 and the sliding strip 13 to move at the same time, so that the lock head 9 is separated from the mating groove 14, realizing unlocking and quick extraction of the moisture box 2. When the external force is released, the pressure spring 20 and the return spring 15 work together to automatically return the trigger frame 17 and the sliding strip 13 to their original positions and restore the locking preparation state. The whole process realizes the efficient coordinated work of automatic locking, stable limiting and quick unlocking. This portable tobacco storage box features a modular and detachable design for the moisture-proof and locking components. The components are arranged in a compact and orderly manner and integrated into the box body without adding any redundant space. This makes the entire storage box small and lightweight, easy to hold and store without causing too much burden, laying a solid foundation for portability. In terms of functionality, the unique locking component plays a key role. The automatic locking and convenient unlocking mechanism, through the coordinated operation of the fixing base 12, sliding bar 13, lock head 9 and other structures, keeps the moisture-proof box 2 stably fixed inside the box. When it is necessary to carry the storage box for travel, the moisture-proof box 2 will not shift due to shaking, ensuring the safety and dryness of the tobacco inside. Moreover, the quick unlocking function of the trigger frame 17 with the spring structure allows users to replace the moisture-proof material without the need for additional tools. It can be completed with one click, which greatly improves the convenience of the function and further enhances the portability. From a user experience perspective, in daily life, users can carry the storage box with them without any pressure and access their tobacco at any time. During travel or outdoor activities, its lightweight appearance and convenient operation mean that users do not need to spend too much effort on storing and accessing tobacco, achieving "take it with you wherever you go, use it whenever you want." It fully meets users' practical needs for portable tobacco storage and provides them with a convenient user experience.
