[0026] Referring to Figure 1 is a structural schematic diagram of a vacuum-packed electronic cigarette in an embodiment.

[0027] Referring to Figure 1 A vacuum-packed electronic cigarette includes an electronic cigarette 10 pre-filled with oil and a packaging bag 20. The electronic cigarette 10 is contained in the packaging bag 20, which is sealed and vacuumized. The electronic cigarette 10 is provided with a vacuumizing assembly 16, which is in communication with the packaging bag 20. Referring to Figures 2-4The electronic cigarette 10 includes a compatible battery host 14 and an atomizer 12. The atomizer 12 includes a housing 122, a base 124, and an atomizing component 126. The housing 122 includes a mouthpiece end and an open end. The base 124 is inserted into the open end of the housing 122. The atomizing component 126 is disposed in the cavity formed by the housing 122 and the base 124. The cavity includes an oil storage chamber 128 and an atomizing chamber 129. The oil storage chamber 128 is filled with oil storage cotton, and the oil storage cotton is pre-injected with e-liquid.

[0028] The vacuum-packed e-cigarette 10 includes a pre-filled e-cigarette 10 and a packaging bag 20. By setting a vacuum assembly 16 inside the pre-filled e-cigarette 10 and communicating with the packaging bag 20, the packaging bag 20 simultaneously extracts air from inside the e-cigarette 10 when vacuuming, so as to maintain the air pressure balance between the packaging bag 20 and the e-cigarette 10 and avoid leakage caused by air pressure imbalance. At the same time, after vacuuming, the packaging bag 20 shrinks and seals tightly against the outside of the e-cigarette 10. There is no air inside the packaging bag 20, which can prevent the pre-filled e-liquid inside the e-cigarette 10 from reacting with air and causing changes in taste or even deterioration. This helps to maintain the freshness and original taste of the e-liquid and improve the user experience.

[0029] For details, please refer to Figure 3 , Figure 4 The vacuum assembly 16 includes a vacuum airflow channel 162, a pressure relief channel 164, and an oil storage cotton. The vacuum airflow channel 162 is located inside the oil storage chamber 128. The oil storage cotton is pre-injected with e-liquid. Before the e-cigarette 10 is placed in the packaging bag 20, the pressure inside the e-cigarette 10 is balanced with the external atmospheric pressure, and the e-liquid will not leak out. When the e-cigarette 10 is placed in the packaging bag 20 and vacuumed and sealed, the air inside the packaging bag 20 is quickly evacuated to create a vacuum. In order to ensure that the air pressure inside the e-cigarette 10 and the packaging bag 20 are balanced and that the e-cigarette 10 does not leak, the air inside the e-cigarette 10 needs to be expelled. The air inside the e-cigarette 10 is expelled through the vacuum airflow channel 162 and the pressure relief channel 164 according to a certain path, so that the e-liquid is not squeezed out while the air is being expelled. The air inside the e-cigarette 10 flows through the vacuum airflow channel 162 to the pressure relief channel 164, and then is expelled from the e-cigarette 10 through the pressure relief channel 164. If e-liquid products are vacuum-sealed, the e-liquid will be extracted, causing e-liquid leakage and contamination of the packaging bag.

[0030] In this embodiment, the vacuum airflow channel 162 is located on the side of the oil-collecting cotton and is an air groove extending from the bottom to the top of the oil-collecting cotton. The oil-collecting cotton is a porous oil-guiding and oil-collecting medium. Since e-liquid is pre-injected into the oil-collecting cotton, a small amount of air bubbles will inevitably be mixed in. The air bubbles are discharged from the vacuum airflow channel 162 on the side of the oil-collecting cotton. The path is regular, and the air bubbles will not squeeze out a small amount of e-liquid due to running around inside the oil-collecting cotton. This helps the air bubbles to be discharged along the preset path, resulting in stable and smooth exhaust.

[0031] Further, the oil storage cotton side is provided with at least two symmetrical vacuum air flow channels 162, which are more conducive to the further stable and smooth discharge of the air bubbles in the oil storage cotton.

[0032] In another embodiment, the vacuum air flow channel 162 is arranged on the inner wall of the oil storage cavity 128 and is an air groove extending from the bottom of the oil storage cavity 128 to the top of the oil storage cavity 128. The vacuum air flow channel 162 arranged on the inner wall of the oil storage cavity 128 can also make the mixed small amount of air bubbles in the oil storage cotton stably and smoothly discharged through the preset path.

[0033] Further, the inner wall of the oil storage cavity 128 is provided with at least two symmetrical vacuum air flow channels 162, which are also conducive to the further stable and smooth discharge of the air bubbles in the oil storage cotton.

[0034] In this embodiment, the pressure relief channel 164 includes a pressure relief hole 1642 and a pressure relief cotton 1644. The pressure relief hole 1642 is arranged at the top of the oil storage cavity 128, the pressure relief cotton 1644 blocks the pressure relief hole 1642, and the pressure relief hole 1642 is communicated with the mouthpiece of the shell 122 or the atomizing cavity 129 through the pressure relief cotton 1644. Because the electronic cigarette 10 is usually placed with the mouthpiece upward, the tobacco tar will have a small gap 1646 or gap at the top of the oil storage cavity 128 due to gravity. The pressure relief hole 1642 is arranged at the top of the oil storage cavity 128 to avoid the tobacco tar extruding the pressure relief hole 1642 to cause the air exhaust not to be smooth. The pressure relief cotton 1644 blocks the pressure relief hole 1642. If a small amount of tobacco tar leaks out due to uneven injection speed and is not timely absorbed by the oil storage cotton, the pressure relief cotton 1644 can absorb the leaked tobacco tar, so that the tobacco tar will not leak out of the electronic cigarette 10, which is conducive to keeping the atomizing cavity 129 and the mouthpiece of the electronic cigarette 10 clean.

[0035] In another embodiment, a gap 1646 is arranged between the top of the oil storage cavity 128 and the top of the atomizing cavity 129. The gap 1646 communicates the top of the oil storage cavity 128 with the top of the atomizing cavity 129. The gap 1646 and the atomizing cavity 129 form the pressure relief channel 164, or the gap 1646 and the mouthpiece form the pressure relief channel 164. Because the electronic cigarette 10 is usually placed with the mouthpiece upward, the tobacco tar will have a small gap 1646 or gap at the top of the oil storage cavity 128 due to gravity. The pressure relief hole 1642 is arranged at the top of the oil storage cavity 128 to avoid the tobacco tar extruding the pressure relief hole 1642 to cause the air exhaust not to be smooth. The discharged air can flow out from the mouthpiece or the atomizing cavity 129. Of course, when the pressure relief channel 164 is composed of the gap 1646 and the atomizing cavity 129, a small amount of tobacco tar that is not timely absorbed due to uneven injection speed and leaks out will be absorbed by the atomizing assembly 126 in the atomizer 12, so that the tobacco tar will not leak out of the electronic cigarette 10, which is conducive to keeping the atomizing cavity 129 and the mouthpiece of the electronic cigarette 10 clean.

[0036] Please refer toFigure 1 In the embodiment, the packaging bag 20 comprises a containing part 22 and a sealing part 24, the electronic cigarette 10 is contained in the containing part 22, and the containing part 22 is vacuumized and sealed through the sealing part 24. After the electronic cigarette 10 is placed in the containing part 22, the containing part 22 can be vacuumized and sealed through the sealing part 24, so that the containing part 22 cannot enter air again, and the vacuum state of the containing part 22 is maintained. The sealing part 24 is usually arranged at the edge of the packaging bag 20.

[0037] Further, a tear opening 26 is arranged between the containing part 22 and the sealing part 24, the packaging bag 20 can be easily torn through the tear opening 26, so that the electronic cigarette 10 can be taken out. The tear opening 26 can be two, and is symmetrically arranged at the side of the packaging bag 20. In another embodiment, a crease can also be arranged between the containing part 22 and the sealing part 24, the crease is arranged along the two symmetrical tear openings 26, and can guide the user to tear or cut along the crease from the tear opening 26.

[0038] The technical features of the above embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that the combinations are within the scope of the present application.
