[0001] The utility model relates to the technical field of anti - oil - leakage of electronic cigarettes, in particular to an anti - negative - pressure oil - leakage structure and an electronic cigarette. Background Technique
[0002] In electronic cigarette devices, oil leakage often occurs because the inner cavity of the device is in a negative - pressure environment, that is, the pressure in the oil storage cotton is greater than the pressure inside the device. The oil will gather in the middle of the oil storage cotton and flow out along the heating wire assembly, resulting in an oil - leakage phenomenon, which affects the service life of the electronic cigarette. The existing anti - negative - pressure oil - leakage structure opens air - vent holes inside the silicone of the cartridge, and the inner cavity of the air - vent holes is indirectly communicated with the outside, so as to facilitate the release of the negative pressure generated in the inner cavity of the oil - storage tube and keep the pressure in the inner cavity of the oil - storage tube consistent with the outside, thereby preventing the oil - leakage phenomenon.
[0003] However, for the atomizing core, the e - liquid cannot be effectively converted into mist, resulting in the e - liquid staying at the cartridge. During the process of the electronic cigarette being placed horizontally when idle, the e - liquid will seep out from the mouthpiece, causing pollution to the idle environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] The present utility model provides as Figures 1-6An anti-negative pressure oil leakage structure and an electronic cigarette are shown, including an electronic cigarette body 1. A cartridge 2 is fixedly connected to the top of the electronic cigarette body 1. An absorption mechanism is provided on the cartridge 2. The absorption mechanism includes two oil absorption components and two movable components. Each of the two oil absorption components includes a first mounting frame 7, a first oil absorption foam 8, a second mounting frame 13, a second oil absorption foam 14, three lower oil-permeable holes 5 and three upper oil-permeable holes 16. The three lower oil-permeable holes 5 are opened at the lower side of one side of the cartridge 2. The first oil absorption foam 8 is arranged in the first mounting frame 7. The first mounting frame 7 is arranged on one side of the cartridge 2. The three upper oil-permeable holes 16 are opened at the upper side of the other side of the cartridge 2. The second oil absorption foam 14 is arranged in the second mounting frame 13. The second mounting frame 13 is arranged on the other side of the cartridge 2. The two first oil absorption foams 8 and the two second oil absorption foams 14 are both made of polyurethane foam. A plurality of drainage grooves are opened on the inner wall of the cartridge 2. The plurality of drainage grooves distributed above are all communicated at both ends of the six upper oil-permeable holes 16. The plurality of drainage grooves distributed below are all communicated at both ends of the six lower oil-permeable holes 5. The electronic cigarette body 1 is a prior art. An atomizer and the like are arranged inside to atomize the e-liquid. During use, the first mounting frame 7 and the second mounting frame 13 are respectively slid upward. The first oil absorption foam 8 moves along with the first mounting frame 7, and the second oil absorption foam 14 moves along with the second mounting frame 13. The e-liquid near the lower part of the inner wall of the cartridge 2 flows from the lower drainage grooves to the lower oil-permeable holes 5. The first oil absorption foam 8 absorbs the e-liquid flowing out from the lower oil-permeable holes 5 distributed on the front and back sides of the cartridge 2. The e-liquid near the upper part of the inner wall of the cartridge 2 flows from the upper drainage grooves to the upper oil-permeable holes 16. The second oil absorption foam 14 absorbs the e-liquid flowing out from the upper oil-permeable holes 16 distributed on the left and right sides of the cartridge 2. The polyurethane foam is a material that absorbs oil but not water and will not absorb the aerosol, which does not affect the user's use. In summary, the problem that the e-liquid will seep out from the mouthpiece and pollute the placement environment of the electronic cigarette is solved.
[0026] Both of the two movable components include a first outer frame 6, a second outer frame 17, two first slide rails 3, two first sliders 4, two fixing members 9, two sliding members 10, two springs 11, two second sliders 12, two second slide rails 15, two rotating shafts 18 and two abutting plates 19. The two first slide rails 3 are both fixedly connected to the cartridge 2. The two first sliders 4 are respectively arranged in the two first slide rails 3. The two first sliders 4 can slide in the two first slide rails 3. The first outer frame 6 is fixedly connected to one side of the two first sliders 4. The two fixing members 9 are respectively fixedly connected to both ends of the top of the first outer frame 6. A chute is formed on one side of each of the two fixing members 9. The two springs 11 are respectively arranged in the two chutes. One end of each of the two springs 11 is fixedly connected to the fixing member 9, and the other end of each of the two springs 11 is fixedly connected to the two sliding members 10. The two second slide rails 15 are both fixedly connected to the cartridge 2. The two second sliders 12 are respectively arranged in the two second slide rails 15. The two second sliders 12 can slide in the two second slide rails 15. The second outer frame 17 is fixedly connected between the two second sliders 12. The two rotating shafts 18 are respectively fixedly connected to both ends of the top of the second outer frame 17. A round hole is formed at one end of each of the two abutting plates 19. The two rotating shafts 18 are respectively arranged in the two round holes. The materials of the four first sliders 4 and the four second sliders 12 are both silicone rubber. First, during the use of the electronic cigarette, the first outer frame 6 is slid. The first oil-absorbing foam 8 in the first mounting frame 7 moves along with the first outer frame 6. The first oil-absorbing foam 8 moves to block the lower oil-permeating hole 5 during the movement. The blocking area determines the exhaust volume of the lower oil-permeating hole 5. The taste of the aerosol is slightly adjusted with the change of the exhaust volume. Similarly, the second slider 12 is operated to adjust the blocking area of the upper oil-permeating hole 16. After the use of the electronic cigarette, the first outer frame 6 is moved downward to completely block the lower oil-permeating hole 5 from the outside, and the second outer frame 17 is moved upward to completely block the upper oil-permeating hole 16 from the outside, so that the first oil-absorbing foam 8 and the second oil-absorbing foam 14 can timely absorb the e-liquid oozing from the oil-permeating holes. In summary, the problem that the intake and exhaust cannot be adjusted, resulting in insufficient atomization of the e-liquid and an increase in the unatomized e-liquid staying at the cartridge 2, is solved.
[0027] Two first mounting frames 7 are respectively arranged in two first outer frames 6, two second mounting frames 13 are respectively arranged in two second outer frames 17, four sliding members 10 are all arranged on the tops of the two first mounting frames 7, and four abutting plates 19 are all arranged on the tops of the two second mounting frames 13. First, press the sliding member 10 in the direction of the spring 11. The spring 11 contracts between the sliding member 10 and the fixing member 9 as the sliding member 10 moves. The sliding member 10 enters the fixing member 9 to cancel the limit on the first mounting frame 7. Move the first mounting frame 7 upward, take out the first oil-absorbing foam 8 from the first mounting frame 7 and replace it with a new first oil-absorbing foam 8. Place the first mounting frame 7 into the first outer frame 6 with the first oil-absorbing foam 8 facing the lower oil-permeable hole 5. Cancel the restriction on the sliding member 10. The spring 11 resets and drives the sliding member 10 to move between the first mounting frame 7 and the first outer frame 6. The sliding member 10 and the first outer frame 6 limit the first mounting frame 7, realizing the replacement of the first oil-absorbing foam 7. Then, rotate the two abutting plates 19 to cancel the limit on the second mounting frame 13. The abutting plates 19 rotate around the rotating shaft 18. Move the second mounting frame 13 upward until the second oil-absorbing foam 14 can be taken out. Take out and replace the second oil-absorbing foam 14. Slide the second oil-absorbing foam 14 into the second outer frame 17 with the second oil-absorbing foam 14 facing the upper oil-permeable hole 16. Rotate the two abutting plates 19 to the top of the second mounting frame 13. The abutting plates 19 and the second outer frame 17 limit the second mounting frame 13, realizing the replacement of the second oil-absorbing foam 14. In summary, the problem of inconvenient replacement of the oil-absorbing foam is solved.
