FIG. 1 toFIG. 5 , an electronic cigarette with breathing sensing function in accordance with the present invention is shown. The electronic cigarette includes amouthpiece section 1, anatomizing section 2 and arod section 3 from top to bottom, respectively. Themouthpiece section 1 is used to provide asuction nozzle 11. The smoke generated from the atomizingsection 2 passes through themouthpiece section 1 and finally reaches the user's mouth. When the electronic cigarette is used, themouthpiece section 1 is directly held in the user's mouth. Therod section 3 is mounted on a bottom of the electronic cigarette, which is gripped by user's hand. - The
rod section 3 has afirst cylinder 30 for accommodating apower source 31. Thepower source 31 is installed in thefirst cylinder 30 and provides energy for the atomizingsection 2. Thefirst cylinder 30 has anairflow sensor 32 arranged along a longitudinal direction of thepower source 31. Theairflow sensor 32 can installed at a bottom end or a top end of thepower source 31. The atomizingsection 2 is arranged between themouthpiece section 1 and therod section 3. The atomizingsection 2 includes asecond cylinder 20, asmoke duct 21 and anatomizer 22. One end of thesecond cylinder 20 is connected to themouthpiece section 1, and the other end of thesecond cylinder 20 is connected to thefirst cylinder 30. - An inner wall of the
second cylinder 20 and an outer wall of thesmoke duct 21 are together formed a space which works as asmoke oil storage 23 for containing smoke oil. Thesmoke duct 21 passes through thesecond cylinder 20. In this embodiment, thesmoke duct 21 includes a guidingcavity 210 which is arranged at a top of thesmoke duct 21 and extended into themouthpiece section 1, and anatomization cavity 211 which is arranged at a bottom of thesmoke duct 21 and communicated with thesecond cylinder 20. Theatomizer 22 is installed in theatomization cavity 211. The working state of theatomizer 22 is controlled by theairflow sensor 32. According to sensing result of theairflow sensor 32, theatomizer 22 is turned on or turned off. A bottom of theatomizer 22 has awaterproof membrane 24, an edge of thewaterproof membrane 24 is connected with an inner wall of thesmoke duct 21. Thewaterproof membrane 24 seals the bottom of theatomizer 22. Thewaterproof membrane 24, themouthpiece section 1, thesmoke duct 21 and thefirst cylinder 30 are communicated to each other to form an airflow channel, so that the external airflow can enter in the airflow duct to trigger theairflow sensor 32. Thewaterproof membrane 24 has a special material which prevents the liquid smoke oil in thesmoke oil storage 23 from passing through thewaterproof membrane 24, and allows the airflow passing through thewaterproof membrane 24.

So that a sensing airflow is formed from a bottom end of thefirst cylinder 30, through thewaterproof membrane 24 into theatomizer 22 and thesmoke duct 21, and through thesmoke duct 21 into the user's mouth. The sensing airflow triggers theairflow sensor 32, thereby turns on theatomizer 22, so that theatomizer 22 starts to work. Then the smoke particles generated by theatomizer 22 enter themouthpiece section 1 through thesmoke duct 21 into the user's mouth. Therefore, the electronic cigarette with breath sensing function not only realizes the function of automatically turning on thepower source 31 through the suction action. Moreover, theairflow sensor 32 and thesecond cylinder 20 containing the smoke oil are arranged in a separated longitudinal direction. It is no longer necessary to provide a separate installation structure for theairflow sensor 32 in the atomizingsection 2. So that the electronic cigarette has a slender, light and coordinated structure, and can also avoid the leakage of smoke oil. - With reference to

Theheating wire 221 is used to heat up theheater 220, and theheater 220 is used to heat up the oil-absorbingcotton 222, thereby atomizing the smoke oil in the oil-absorbingcotton 222. In this embodiment, theheater 220 is a ceramic tube, the smoke oil in thesmoke oil storage 23 enters the oil-absorption cotton 222 through the oil inlet holes 212 of theatomization cavity 211, and the smoke oil is absorbed by the oil-absorption cotton 222. When theatomizer 22 is turned on, theheating wire 221 is heating up to rise the temperature of theheater 220. Then the smoke oil absorbed on the oil-absorbingcotton 222 is atomized to generate smoke particles, and the smoke particles enter the guidingcavity 210 from theatomization cavity 211 and inhaled by the user. - In order to facilitate the replacement of the
