In use, booster body 26 works so that the pressure in liquid storage cylinder 281 increases, and tobacco juice compression force effect is led to successively It overflows from liquid outlet 1342 after crossing the first tobacco juice runner 201 and the second tobacco juice runner 130, and then is absorbed simultaneously by heating structure 138 Heating atomization generates smoke.Arrow direction is glide path of the tobacco juice in the first tobacco juice runner 201 in Fig. 6.It needs Illustrate, the power of booster body 26 is controllable, and tobacco juice is enabled to be slowly escaped through via liquid outlet 1342, rather than sprays Go out.

In addition, the first tobacco juice runner 201 and the second tobacco juice runner 130 collectively form tobacco juice runner (figure does not mark), in order to It prevents tobacco juice from flowing back, check valve (not shown) is provided in tobacco juice runner.It is to be appreciated that pressure channel is let out in order to prevent It presses, check valve (not shown) is also equipped in pressure channel.

In present embodiment, electronic cigarette further includes the detection device 30 for detecting tobacco juice, and the setting of detection device 30 is going out At liquid mouth 1342.Supply unit includes battery 40 and controller 50, and battery 40 electrically connects with controller 50 and heating structure 138 It connects, detection device 30 is electrically connected with controller 50.When thering is tobacco juice to flow through at detection device 30 detects liquid outlet 1342, control Device 50 processed just can control battery 40 to power to heating structure 138, thereby it is ensured that when heating structure 138 works, tobacco juice will Or heating structure 138 has been touched, heating structure 138 just has begun work when tobacco juice being avoided not reach liquid outlet 1342 also The case where in turn resulting in 138 dry combustion method of heating structure.In present embodiment, detection device 30 is liquid inductive switch.

Electronic cigarette provided by the utility model, tobacco juice are independently arranged at the outside of atomizer 10 so that on atomizer 10 Heating structure 138 is not immersed in tobacco juice, only as user in use, tobacco juice just enters to mist by the second tobacco juice runner 130 Change device 10 atomization chamber 110 in so that is contacted with heating structure 138, and the heat effect of heating structure 138 mist metaplasia at Smog avoids due to heating structure 138 absorbs tobacco juice when that reaches saturation there is a situation where tobacco juice leaks, improves making for user With experience.

It is enlightenment, through the above description, relevant work with the above-mentioned desirable embodiment according to the utility model Personnel can carry out various changes and amendments in without departing from the scope of the utility model completely.This item utility model Technical scope is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
