Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to a large-capacity electronic cigarette e-liquid storage container. Background Technology

[0002] Currently, with the popularization of e-cigarettes, users have put forward higher requirements for e-liquid capacity in order to obtain longer battery life. Therefore, large-capacity e-liquid tanks have become the mainstream trend in the market, and the requirements for stability are also increasing. In related technologies, existing e-cigarettes with a capacity of 15ml and above have poor stability of e-liquid storage tanks due to the large liquid volume and high liquid level after filling, resulting in greater pressure fluctuations inside and outside the tank and failing to meet the ever-changing user needs. Utility Model Content

[0003] This utility model aims to at least partially solve the technical problems in related technologies. In existing electronic cigarettes, the internal temperature of the e-liquid tank fluctuates during use, leading to the following technical problems: Leakage issue: When the internal air pressure is higher than the external ambient air pressure, the e-liquid is easily squeezed out by the high pressure and leaks from the mouthpiece, air intake or atomizer connection, causing pollution, waste and a worse user experience.

[0004] Weakened e-liquid supply problem: When the air pressure inside the e-liquid tank is lower than the external air pressure (such as in low temperature environments or high altitude areas), a negative pressure is generated, which creates a "suction resistance" effect on the e-liquid inside the tank, resulting in poor e-liquid supply. The atomizer core cannot receive timely and sufficient e-liquid supply, which leads to a "burnt" phenomenon, producing a burnt taste and seriously affecting the user experience.

[0005] The problem of lag in balancing: Traditional oil tanks usually rely on tiny air inlets to balance air pressure, but their response speed is slow and they are unable to cope with rapid and frequent temperature changes, and cannot effectively balance the pressure difference between the inside and outside in real time.

[0006] The problem of unidirectional balance: Traditional oil tanks balance air pressure through air inlets, which can only achieve the "gas replenishment" effect when the internal pressure is lower than the external pressure, but cannot solve the problem of "excessive extrusion of compressed liquid" caused by the expansion of internal gas.

[0007] Frequent air exchange issues: Traditional e-cigarettes typically achieve air pressure balance by introducing air through the air exchange port when the e-liquid is consumed normally. However, the amount of air exchange is usually uncontrollable, meaning that each air exchange will cause random fluctuations, affecting the liquid supply and vaping. Each air exchange is considered a vaping cycle. Traditional cotton wick e-cigarettes usually exchange air after one puff, meaning that the number of puffs in one cycle is only one puff. This is too frequent, and the instability caused by the frequent air exchange has a great impact on the consistency of vaping, further limiting the e-liquid mixing and cotton wrapping processes.

[0008] Therefore, one objective of this utility model is to provide a large-capacity electronic cigarette e-liquid storage container, comprising: case; The inner shell is disposed within the outer shell and together with the outer shell defines a deformable space, and the inner shell has an oil storage cavity for containing e-liquid; At least two elastic membranes are disposed on the inner shell and deform together toward the oil storage cavity or the deformation space as the pressure in the oil storage cavity changes, so that the space of the oil storage cavity shrinks or increases with the at least two elastic membranes.

[0009] Preferably, each of the elastic membranes comprises: The deformable part comprises a plurality of bends connected in sequence along the radial direction, and the diameter of the plurality of bends increases sequentially from the inside to the outside. A connecting portion is provided around the deformable portion and abuts against the inner wall of the oil storage cavity.

[0010] Preferably, each of the bending portions includes a first deformation surface and a second deformation surface, and the first deformation surface and the second deformation surface are perpendicular to each other.

[0011] Preferably, the inner shell has at least two mounting openings on its side, and at least two elastic membranes are respectively disposed in at least two mounting openings.

[0012] Preferably, the inner shell has an annular groove surrounding the mounting opening, and a fixing buckle is embedded in the annular groove to secure the connecting part within the mounting opening.

[0013] Preferably, a connecting wall is provided between the annular groove and the mounting port, the connecting part is fitted with the connecting wall, and the fixing buckle has a locking groove facing the connecting wall, the locking groove being used to engage and fix the connecting part with the connecting wall.

[0014] Preferably, at least two of the elastic membranes are disposed on two opposite sides of the inner shell or on two adjacent sides of the inner shell.

[0015] Preferably, the elastic membrane is circular, elliptical, square, or annular.

[0016] Preferably, the inner shell is provided with a gas channel, which is connected to the oil storage chamber through an atomizing core.

[0017] Preferably, a sealing base is connected to the bottom of the atomizing core, and the sealing base seals the bottom of the inner shell.

[0018] The above-described solution of this utility model has at least the following beneficial effects: The large-capacity e-liquid storage chamber provided by this utility model, by setting at least two elastic membranes on the inner shell, makes the storage chamber have a larger capacity range. It can take advantage of the advantages of long battery life, multiple puffs and flavor brought by the large capacity. When the pressure in the storage chamber changes, the elastic membrane can deform towards the deformation space to release the internal positive pressure in time, thereby eliminating the problem of e-liquid leakage caused by pressure accumulation. The deformation of the elastic membrane can also effectively compensate for negative pressure to adapt to air pressure changes under different environmental conditions such as high and low temperature, high and low altitude, etc., expanding the application range of the product. It can also ensure unobstructed e-liquid supply, completely eliminate the "dry burning" phenomenon, and improve the consistency of flavor and user experience.

[0028] The following describes in detail, with reference to the accompanying drawings, a large-capacity electronic cigarette e-liquid storage compartment of this utility model.

[0029] Reference Figures 1 to 6 As shown, the large-capacity e-cigarette oil storage compartment provided in this embodiment includes: a shell 10, an inner shell 20, and at least two elastic membranes 30. The inner shell 20 is disposed inside the shell 10, which can minimize the design difficulties caused by changes in appearance. The inner shell 20 and the shell 10 together define a deformation space 101, which allows for more applicable scenarios between the inner shell 20 and the outer shell. The inner shell 20 has an oil storage cavity 201 for containing e-cigarette oil, and at least two elastic membranes 30 are disposed on the inner shell 20 and are attached to the inner shell along with the oil storage cavity. The pressure change within cavity 201 causes deformation towards the oil storage cavity 201 or the deformation space 101, so that the space of the oil storage cavity 201 shrinks or expands with the at least two elastic membranes 30. The inner shell 20 is provided with a gas channel 24, which is connected to the oil storage cavity 201 through the atomizing core 50, so that the e-liquid stored in the oil storage cavity 201 can be atomized by the atomizing core 50 and then sucked out from the gas channel 24. Optionally, a sealing base 60 is connected to the bottom of the atomizing core 50, and the sealing base 60 seals the bottom of the inner shell 20.

[0030] In this embodiment, when the ambient temperature rises or the overall air pressure of the e-liquid storage chamber increases due to special usage scenarios, the e-liquid and air in the storage chamber 201 expand and the pressure increases. This will preferentially squeeze the elastic membrane 30 toward the deformation space 101 to deform, thereby effectively reducing the internal pressure of the reservoir and preventing the internal high pressure from squeezing out the e-liquid and causing leakage.

[0031] Furthermore, when the ambient temperature decreases, causing negative pressure to form inside the e-liquid storage chamber: the air inside the storage cavity 201 contracts, creating negative pressure. External atmospheric pressure forces the elastic membrane 30 to deform into the storage cavity 201. This deformation of the elastic membrane 30 compensates for the reduced space in the storage cavity 201 due to cooling, thus maintaining a basic balance between the pressure inside the storage cavity 201 and the external atmospheric pressure. This ensures that the e-liquid can flow smoothly to the atomizer core 50 for atomization even under negative pressure, preventing dry burning. Even further, when e-liquid consumption causes negative pressure to form inside the e-liquid tank: the air inside the storage cavity 201 generates negative pressure... External atmospheric pressure forces the elastic membrane 30 to deform inward toward the oil storage chamber 201. This deformation of the elastic membrane 30 compensates for the increased space in the oil storage chamber 201 due to e-liquid consumption, thereby increasing the number of breaths required for ventilation and effectively reducing liquid supply fluctuations caused by frequent ventilation. It can be understood that through the bidirectional deformation of the elastic membrane 30 toward the oil storage chamber 201 or toward the deformation space 101, the oil storage chamber 201 can be dynamically adjusted according to the air pressure of the liquid reservoir, reducing the pressure difference fluctuations inside and outside the oil storage chamber 201 and ensuring that the oil storage chamber 201 can maintain a stable pressure state.

[0032] Reference Figure 2 and Figure 4 As shown, each elastic membrane 30 includes a deformation portion 31 and a connecting portion 32. The deformation portion 31 comprises a plurality of bends connected sequentially in the radial direction, and the diameter of the plurality of bends increases sequentially from the inside to the outside. When the deformation portion 31 is affected by the pressure in the oil storage cavity 201, the plurality of bends are stretched and unfolded under the pressure. Each bend includes a first deformation surface 311 and a second deformation surface 312, and the first deformation surface 311 and the second deformation surface 312 are perpendicular to each other. When each bend is unfolded, the first deformation surface 311 and the second deformation surface 312 can be roughly connected to form the same arc surface. After the deformation part 31 is deformed, it can increase the space of the oil storage cavity 201 or reduce the space of the liquid reservoir, thereby realizing automatic adjustment of the pressure difference of the oil storage cavity 201. The connecting part 32 is arranged around the deformation part 31 and abuts against the inner wall of the oil storage cavity 201, so that the elastic membrane 30 and the inner shell 20 are more tightly attached and fixed.

[0033] Furthermore, the inner shell 20 has at least two mounting ports 21 on its side, and at least two elastic membranes 30 are respectively disposed in the at least two mounting ports 21. The at least two mounting ports 21 can be on two opposite sides of the inner shell 20 or on two adjacent sides of the inner shell 20, so that the at least two elastic membranes 30 can be disposed on two opposite sides of the inner shell 20 or on two adjacent sides of the inner shell 20. In other embodiments, to increase the capacity of the oil storage cavity 201, the number of elastic membranes 30 can also be three, four, etc., therefore the corresponding elastic membranes 30 on the inner shell 20... The mounting port 21 can also be configured according to the number of elastic membranes 30. No limitation is made here. It can be understood that by increasing the number of elastic membranes 30, the oil storage chamber 201 in this embodiment can accommodate a larger range of oil tank capacity compared to a single elastic membrane 30. This further leverages the advantages of large capacity, such as long endurance, multiple mouths, and enhanced taste. It can also avoid the problem of failure due to a single elastic membrane 30 falling or exceeding the deformation threshold. The overall structure does not require complex electronic or mechanical control components, is inexpensive, easy to manufacture and assemble, and has higher reliability.

[0034] As a preferred embodiment, the elastic membrane 30 is circular, elliptical, square, or annular, for example... Figure 5 and Figure 6 The elastic membrane 30 shown is elliptical, which allows for a wider variety of optional shapes and makes it suitable for various electronic cigarette assemblies.

[0035] Reference Figure 2 and Figure 3 As shown, the inner shell 20 is provided with an annular groove 22 surrounding the mounting port 21. A fixing buckle 40 is embedded in the annular groove 22. The fixing buckle 40 clamps the connecting part 32 into the mounting port 21. Furthermore, there is a connecting wall 23 between the annular groove 22 and the mounting port 21. The connecting part 32 fits against the connecting wall 23, and the fixing buckle 40 has a locking groove 41 facing the connecting wall 23. The locking groove 41 is used to fit and fix the connecting part 32 and the connecting wall 23. When the elastic membrane 30 is fixed to the inner shell 20, the fixing buckle 40 can be embedded in the annular groove 22. At the same time, the connecting part 32 and the connecting wall 23 are also embedded in the locking groove 41, so that the fixing buckle 40 can lock and fix the connecting part 32 and the connecting wall 23. The elastic membrane 30 and the inner shell 20 fit more tightly, and the sealing of the oil storage cavity 201 is better.

[0036] The large-capacity e-liquid storage chamber provided by this utility model, by setting at least two elastic membranes 30 on the inner shell 20, makes the storage chamber have a larger capacity range. It can take advantage of the advantages of long battery life, multiple puffs and flavor brought by large capacity. When the pressure in the storage chamber 201 changes, the elastic membranes 30 can deform towards the deformation space 101 to release the internal positive pressure in time, thereby eliminating the problem of e-liquid leakage caused by pressure accumulation. The deformation of the elastic membranes 30 can also effectively compensate for negative pressure to adapt to air pressure changes under different environmental conditions such as high and low temperature and high and low altitude, expanding the application range of the product. It can also ensure that the e-liquid supply channel is unobstructed, completely eliminate the "dry burning" phenomenon, and improve the consistency of flavor and user experience.
