Description
Technical Field
[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette capable of preventing aerosol backflow. Background Art
[0002] Electronic cigarettes are electronic products that imitate cigarettes and have the same appearance as cigarettes. Electronic cigarettes can vaporize liquid containing nicotine through an atomizer for users to inhale. The working principle of electronic cigarettes is that when the user inhales, negative pressure is generated inside the electronic cigarette, which in turn causes external gas to flow into the electronic cigarette through the main air inlet. When the airflow passes through the starter microphone, a start signal is triggered, and then the atomizer is controlled to heat and atomize the e-liquid; the starter microphone is actually a pneumatic switch, and when airflow passes through, a start signal is triggered.
[0003] At present, the internal air intake structure of most electronic cigarettes still adopts a "straight-through" air intake method, lacking a reasonable partition structure. In actual use, it is inevitable that there will be residual aerosol in the airway. Therefore, after the electronic cigarette is finished, the residual aerosol is easy to flow back to the starter microphone, causing the starter microphone to be corroded, causing self-starting or unsmooth starting, which brings a bad user experience.

The start air inlet 72 and the start air outlet 73 are respectively connected with the microphone mounting groove 71, the start air inlet 72 is connected with the air inlet cavity 41, and the start air outlet 73 is connected with the atomization component. During the inhalation process of the electronic cigarette, the external gas flows into the housing 1 through the main air inlet 3, and then flows into the air inlet cavity 41. Most of the air flow will flow into the atomization component through the air inlet cavity 41 to mix with the aerosol; another small part of the flow flows into the start air inlet 72 through the air inlet cavity 41, and then flows into the microphone mounting groove 71 to contact the start switch 6, triggering the start signal, so that the atomization component works to heat the smoke oil and atomize it into aerosol; then the start air flow will flow out of the microphone mounting groove 71 through the start air outlet 73, and then flow into the atomization component to mix with the aerosol.
[0026] The electronic cigarette is provided with a microphone silicone 7, and a starting air inlet hole 72 and a starting air outlet hole 73 are provided in the microphone silicone 7; the microphone silicone 7 is used to separate the starting switch 6 from the air inlet cavity 41, so that the possibility of residual aerosol backflow corroding the starting switch 6 can be effectively reduced, thereby improving the working stability of the electronic cigarette and enhancing the user's use experience.
[0027] In order to further reduce the possibility of aerosol backflow to start the switch 6, an airway seal 8 is provided on the mounting bracket 4. The airway seal 8 is made of silicone material.

The air inlet groove 91 is connected to the connecting hole 92 and the first cavity 411 respectively, and the connecting hole 92 is connected to the main air inlet hole 3. During the inhalation of the electronic cigarette, the external gas flows into the connecting hole 92 through the main air inlet hole 3, then flows into the air inlet groove 91, and then flows into the first cavity 411. By providing the air inlet silica gel 9, external dust can be prevented from entering the interior of the electronic cigarette, thereby extending the service life of the electronic cigarette; it can also reduce the possibility of oil leakage from the main air inlet hole 3, thereby improving the user's use experience.
[0030] In order to facilitate the fixing of the air inlet silica gel 9, a positioning column 42 is provided on the mounting bracket 4, and a positioning hole 93 is provided on the air inlet silica gel 9.

The external airflow flows into the start switch 6 through the main air inlet 3 to trigger the start signal; the e-liquid flows from the oil storage cup 10 to the heating core 11. The heating core 11 heats the e-liquid and atomizes it into aerosol. The suction airflow mixes with the atomized aerosol and flows into the nozzle 2, and is finally inhaled by the user to complete the suction process.
[0032] An oil storage cotton 12 is provided in the oil storage cup 10, and the oil storage cotton 12 is connected to the inner wall of the oil storage cup 10, which can prevent the smoke oil from shaking in the oil storage cup 10 and reduce the possibility of smoke oil leakage. The heating core 11 passes through both ends of the oil storage cotton 12, so that the heating core 11 can contact the smoke oil in the oil storage cup 10, so that the smoke oil flows into the heating core 11 for heating and atomization.
[0033] A battery 13 is mounted on the mounting bracket 4 , and the battery 13 is electrically connected to the control board 5 . The electronic cigarette is powered by the battery 13 , so that the heating core 11 can be powered to heat the atomized tobacco oil.
[0034] Working principle:
[0035] When the electronic cigarette is inhaled, the user inhales through the mouthpiece 2, so that negative pressure is generated inside the electronic cigarette, and the external gas flows into the shell 1 through the main air inlet 3; the airflow first flows into the connecting hole 92, then flows into the air inlet groove 91, and then flows into the first cavity 411. The airflow flowing into the first cavity 411 will be divided into two streams, one of which is used as the suction airflow and flows directly into the heating core 11 after passing through the first cavity 411; the other airflow is used as the starting airflow and flows into the microphone mounting groove 71 through the starting air inlet 72, contacts the starting switch 6, triggers the starting signal, and makes the heating core 11 powered on to heat the smoke oil and atomize it into aerosol. The starting airflow flows into the starting air outlet 73 through the microphone mounting groove 71, and then flows into the second cavity 412, the second air hole 82, the connecting groove 83 and the first air hole 81 in sequence, and finally flows into the heating core 11 to mix with the aerosol after atomization. The airflow mixed with the aerosol flows into the suction nozzle 2 through the heating core 11, and is finally sucked out by the user, completing the suction process of the electronic cigarette.
