Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization equipment, and in particular to a large-capacity cartridge with oil leakage prevention. BACKGROUND

[0002] The common cartridges on the market are mainly designed to improve atomization efficiency, prolong service life, and reduce oil leakage. These improvements not only enhance user experience, but also promote the technological progress of the entire industry. In order to achieve the above goals, existing cartridges usually adopt various design schemes to prevent oil leakage. For example, some cartridges increase sealing rings or gaskets to enhance the sealing performance at the interface; others optimize the internal structure, such as adding isolation devices between the oil storage layers or improving the cooperation between the cotton core and the heating element, to reduce the risk of oil leakage. In addition, some cartridges use double or multi-layer outer cotton design to further improve oil absorption and prevent oil leakage.

[0003] Utility model patent publication No. CN221635018U discloses an electronic cigarette cartridge structure, which includes a cartridge shell, an atomization heating element built-in the cartridge shell, and tobacco oil stored in the inner cavity of the cartridge shell. The cartridge shell is provided with a smoke outlet channel, the atomization heating element is electrically connected with the electronic cigarette main body, and the outside of the atomization heating element is sequentially provided with a first oil locking cotton, an inner tube, a second oil locking cotton, and an outer tube from inside to outside. The electronic cigarette cartridge structure can be adapted to electronic cigarettes with larger tobacco oil storage capacity, meeting the needs of consumers for large-capacity electronic cigarettes. However, since the first oil locking cotton in the inner tube of the large-capacity cartridge will mix a large amount of oil during the atomization process, wrapping only one layer of oil locking cotton on the outer side of the inner tube is likely to cause oil leakage. SUMMARY

[0004] The purpose of the present application is to provide a large-capacity cartridge with oil leakage prevention to solve the problem of easy oil leakage of large-capacity cartridges.

[0005] The large-capacity cartridge with oil leakage prevention provided by the present application adopts the following technical scheme:

[0006] A large-capacity cartridge with oil leakage prevention includes:

[0007] A cartridge body for atomizing oil, which includes a heating wire, a mixing cotton, a cartridge support, a first outer wrapping cotton, a cartridge cover, and a second outer wrapping cotton arranged from inside to outside. The mixing cotton forms a gas passage inside, and the heating wire is arranged in the gas passage for atomizing oil.

[0008] By adopting the above technical solution, the mixed cotton is used to absorb the oil, providing oil for the atomization of the heating wire. The heating wire heats and evaporates the oil, atomizing it into vapor to achieve the atomization purpose. The cartridge holder supports the mixed cotton and the heating wire. A first outer layer of cotton is placed on the outside of the cartridge holder, and a second outer layer of cotton is placed on the outside of the cartridge cover. This provides two layers of protection against oil leakage, preventing leakage when the mixed cotton contains a large amount of oil. Furthermore, because the two layers of cotton provide more oil storage space, it avoids the problem of the heating core burning due to continuous heating when the oil supply is insufficient.

[0009] Optionally, the cartridge holder is provided with a first connecting port to connect the mixed cotton and the first outer cotton, and the cartridge cover is provided with a second connecting port to connect the first outer cotton and the second outer cotton.

[0010] By adopting the above technical solution, the first connecting port and the second connecting port connect the mixed cotton, the first outer cotton and the second outer cotton. When there is too much oil in the mixed cotton, the part that leaks out through the connecting port can be avoided, thus preventing the heating wire from being incompletely atomized due to excessive contact with oil.

[0011] Optionally, a limiting ring is provided on the outer casing of the cartridge, and the limiting ring is engaged with the second outer cotton on the lower side of the second outer cotton.

[0012] By adopting the above technical solution, the limiting ring engages with the second outer cotton on the lower side of the second outer cotton, effectively preventing the second outer cotton from shifting and ensuring that the second outer cotton can cover the second connecting opening, thereby ensuring structural stability and sealing.

[0013] Optionally, the blended cotton has a protrusion, and the cartridge holder has a connection notch, with the protrusion corresponding to the connection notch.

[0014] By adopting the above technical solution, the protrusion of the mixed cotton can be engaged with the connection notch of the cartridge holder, thereby preventing the mixed cotton from sliding inside the cartridge holder. Furthermore, through the connection notch, the mixed cotton and the first outer cotton form a large contact area. When there is too much oil in the mixed cotton, the oil can be quickly distributed to the first outer cotton. When there is insufficient oil in the mixed cotton, the protrusion can absorb the oil stored in the first outer cotton.

[0015] Optionally, the first outer cotton layer has a thickened portion, which corresponds to a protrusion, and the protrusion contacts the thickened portion through a connecting notch.

[0016] By adopting the above technical solution, since a lot of oil will seep out when the protrusion contacts the first outer cotton, the first outer cotton is thickened in the part that contacts the protrusion to prevent oil from seeping out from the thickened part and improve the oil leakage prevention performance.

[0017] Optionally, a cartridge base is also included, on which the cartridge itself is mounted.

[0018] By adopting the technical scheme, the combination of the cartridge body and the cartridge base improves the overall stability and safety of the cartridge, the cartridge base not only provides a stable mounting base, but also effectively prevents the cartridge from accidentally falling off or loosening during use, thereby improving product reliability.

[0019] Optionally, the cartridge base is provided with a mounting groove, and a support frame is arranged in the mounting groove and corresponds to the cartridge cover.

[0020] By adopting the technical scheme, the cartridge cover can be stably fixed on the cartridge base, improving the overall structural stability of the cartridge and avoiding loosening or falling off caused by vibration or collision during use.

[0021] Optionally, the cartridge base further comprises a control button and a control knob.

[0022] By adopting the technical scheme, the cartridge base is additionally provided with a control button and a control knob, so that the user can more conveniently adjust the working state of the cartridge, such as power size or mode switching, thereby improving user experience and operation convenience.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. A first outer wrapping cotton is arranged outside the cartridge holder, and a second outer wrapping cotton is arranged outside the cartridge cover, so that the oil can be protected by two layers when it leaks outside, avoiding oil leakage when the mixed cotton oil amount is large. And because the two layers of outer wrapping cotton can provide more oil storage space, it can avoid the problem of burnt core caused by continuous heating of the heating core when the oil supply is insufficient;

[0025] 2. The protruding part of the mixed cotton can be clamped with the connecting gap of the cartridge holder, so as to avoid the mixed cotton from sliding in the cartridge holder, and through the connecting gap, the mixed cotton and the first outer wrapping cotton form a larger contact area, which can quickly dissipate the oil in the mixed cotton to the first outer wrapping cotton when the oil in the mixed cotton is too much, and can absorb the oil stored in the first outer wrapping cotton through the protruding part when the oil in the mixed cotton is insufficient;

[0026] 3. Because the protruding part contacts the first outer wrapping cotton, more oil will seep out, so the first outer wrapping cotton is thickened at the part contacting the protruding part to avoid oil seepage from the thickened part and improve the oil leakage prevention performance.

Corresponding to the connecting gap 132, the mixed cotton 12 is provided with a protruding portion 122, which is clamped at the connecting gap 132, so that the mixed cotton 12 cannot rotate relative to the cartridge support 13, thereby ensuring the stability of the atomization process. In addition, the protruding portion 122 makes the mixed cotton 12 have a larger volume, so that more oil can be stored, thereby improving the capacity of the cartridge. The outer side of the cartridge support 13 is wrapped with a first outer wrapping cotton 14. Since the oil in the mixed cotton 12 can seep out through the first communication port 131 and the connecting gap 132, the first outer wrapping cotton 14 is arranged to absorb the seepage oil. The first outer wrapping cotton 14 is in contact with the mixed cotton 12 at the connecting gap 132. The part of the first outer wrapping cotton 14 corresponding to the connecting gap 132 is a thickened portion 141. Since the thickened portion 141 is directly in contact with the mixed cotton 12 at the connecting gap 132, a thicker thickened portion 141 is arranged to avoid rapid oil penetration and to improve the oil leakage prevention performance.

[0036] With reference to Figure 3 and 4 , the outer side of the first outer wrapping cotton 14 is provided with a cartridge outer cover 15, which extends upward. The atomized oil mist spreads to the outside from the opening at the upper end of the cartridge outer cover 15. The cartridge outer cover 15 is provided with a second communication port 151 and a limiting ring 152. The outer side of the cartridge outer cover 15 is provided with a second outer wrapping cotton 16. The second communication port 151 can communicate the first outer wrapping cotton 14 and the second outer wrapping cotton 16, so as to balance the air pressure inside and outside the cartridge, and enable the second outer wrapping cotton 16 to absorb the seepage oil in the first outer wrapping cotton 14, thereby improving the oil leakage prevention performance. The limiting ring 152 is clamped below the second outer wrapping cotton 16, which can prevent the second outer wrapping cotton 16 from falling off, thereby improving the structural stability of the cartridge.

[0037] With reference to Figure 1 and 2 , the cartridge base 2 includes a detachable top cover 25 and a mounting seat 26. By detaching the top cover 25 and the mounting seat 26, the installation and adjustment of the parts inside the cartridge base 2 can be facilitated. The mounting seat 26 is provided with a mounting groove 21, and the top cover 25 is provided with an opening corresponding to the mounting groove 21. The cartridge body 1 is installed in the mounting groove 21. The mounting groove 21 is provided with a support frame 22 corresponding to the cartridge outer cover 15, which is used to stabilize the cartridge body 1. The bottom surface of the mounting seat 26 is provided with a control button 23 and a control knob 24. The control button 23 and the control knob 24 can be used to conveniently adjust the working state of the cartridge by the user, thereby improving the user experience and the operation convenience.

[0038] The implementation principle of the embodiment of the present application is that the multi-layer coating structure and the optimized connection mode effectively solve the oil leakage problem of the large-capacity cartridge. The design of the heating wire 11 and the mixed cotton 12 ensures uniform atomization and storage of the oil liquid.
