Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic cigarette technology, and in particular relates to an electronic cigarette lithium battery with a protective structure. Background Technology
[0002] With the rapid development of the e-cigarette market and the expanding user base, the safety and reliability of its core component—the lithium battery—have received widespread attention. As the energy source for e-cigarettes, the performance of the lithium battery directly affects the user experience and safety. However, in actual use, lithium batteries face numerous potential risks. For example, during transportation, use, or accidental drops, lithium batteries may be subjected to external impacts or compression, leading to structural damage, short circuits, or even fire and explosion, posing safety hazards to users.
[0003] Currently, most e-cigarette lithium batteries rely primarily on simple plastic or metal casings for protection. While these casings offer some protection against dust and liquids entering the battery, their ability to withstand external impacts is limited. Under significant force, internal structures such as electrodes and separators can easily shift or deform, leading to internal short circuits and other problems. Furthermore, existing battery casing designs typically only accommodate lithium batteries of specific sizes, failing to meet the versatility requirements of different battery models. This not only limits the design flexibility of e-cigarette products but also increases production costs and inventory management complexity.
[0004] In summary, existing lithium battery protection technologies for e-cigarettes have the following shortcomings: First, they are not strong enough to protect against impacts and compressions, making it difficult to effectively protect lithium batteries from external damage; second, they lack universal designs for lithium batteries of different sizes, limiting the flexibility and applicability of the products.

Detailed Implementation
[0025] 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. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0026] This utility model embodiment provides an electronic cigarette lithium battery with a protective structure, such as... Figures 1-3 As shown, it includes: a lithium battery body; a housing 100 for housing the lithium battery body, the housing 100 being composed of two detachable half-shells 1, each half-shell 1 having a receiving cavity 2 for accommodating the lithium battery body; an airbag layer 3 fixed to the cavity wall of the receiving cavity 2, which can be fixed by adhesive; and an inflation assembly installed on the housing 100 for inflating the airbag layer 3 to fix the lithium battery body.
[0027] During production, the lithium battery body is placed into the receiving cavity 2, and then the two half shells 1 are assembled into a whole. The lithium battery body is protected by the shell 100. Then, the airbag layer 3 is inflated by the inflation component, so that the airbag layer 3 expands and fixes the lithium battery body. It can adapt to lithium battery bodies of different sizes, and the airbag layer 3 has a buffer protection function. When the e-cigarette is dropped on the ground, it can buffer and protect the lithium battery body and prevent the impact from damaging the lithium battery body.
[0028] Both of the two half-shells 1 have through slots 4 at the top and bottom to facilitate the passage of wires.
[0029] In a specific implementation, each of the two half-shells 1 is provided with an air duct, which is connected to the inner cavity of the airbag layer 3. The contact surfaces of the two half-shells 1 are respectively provided with a first connecting hole 7 that can be connected. The first connecting hole 7 is connected to the air duct of the half-shell 1 in which it is located, and the inflation component is connected to the air duct.
[0030] When the two half-shells 1 are assembled into a whole, the first connecting holes 7 on the two half-shells 1 are connected, and then the inflation assembly inflates the air. The air enters the airbag layer 3 inside the two half-shells 1 through the air duct, causing the airbag layer 3 to expand and fix the lithium battery body.
[0031] Preferably, a sealing ring 8 is installed on the half-shell 1 outside the first connecting hole 7, which serves as a seal during inflation. It can be installed using an embedded method, or other existing technologies can be employed; there are no excessive restrictions.
[0032] In this embodiment, the two half-shells 1 are rotatably connected by an adapter 5. In this embodiment, the adapter 5 is a hinge, which facilitates opening the two half-shells 1 to disassemble and assemble the lithium battery body.
[0033] Furthermore, the inflation assembly includes:
[0034] A connecting screw 10 is installed on a half-shell 1, and the connecting screw 10 is threadedly connected to a lug 9 on the outer side wall of the half-shell 1.
[0035] A piston housing 15 is fixed to the outer wall of another half-shell 1. The piston housing 15 has a threaded hole 14 that mates with the connecting screw 10 at one end.
[0036] A piston block 13 is provided inside the piston housing 15. A compression spring 12 is provided between the piston block 13 and the other end of the piston housing 15. A second connecting hole 11 is provided at the other end of the piston housing 15. The second connecting hole 11 is connected to the air duct inside the half-shell 1.
[0037] During production, after the two half-shells 1 are joined together, the connecting screw 10 is rotated and enters the threaded hole 14 to connect with the piston shell 15, thereby connecting the two half-shells 1 and installing and protecting the lithium battery body. The connecting screw 10 is rotated again and pushes the piston block 13 to move, squeezing the air in the piston shell 15 into the air duct and then into the airbag layer 3, causing the airbag layer 3 to expand and fix the lithium battery body.
[0038] In summary, this utility model provides an electronic cigarette lithium battery with a protective structure, the working principle of which is as follows:
[0039] The lithium battery body is placed into the receiving cavity 2, and then the two half-shells 1 are assembled into a whole. By rotating the connecting screw 10, the connecting screw 10 enters the threaded hole 14 and connects with the piston shell 15, thereby connecting the two half-shells 1 to install and protect the lithium battery body. Continue to rotate the connecting screw 10, and the connecting screw 10 pushes the piston block 13 to move, squeezing the air in the piston shell 15 into the air duct and then into the airbag layer 3, causing the airbag layer 3 to expand and fix the lithium battery body.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
