In order to promote the leakproofness of liquid storage cylinder 281, between connectedness 24 and the first liquid supply pipe 23, connectedness 24 and liquid storage piece
The sealing element made of silica gel or rubber material is both provided between 28 and between fixing piece 27 and liquid storage piece 28, and (figure is not marked
Go out).It is to be appreciated that in other unshowned embodiments, fixing piece 27 can also omit, at this point, connectedness 24 can be straight
It connects and is connected with liquid storage piece 28, to simplify structure.It is also understood that ground, the second liquid supply pipe 25, fixing piece 27 and connectedness
24 can be omitted, at this point, liquid storage piece 28 is connected directly between the lower section of cover board 21, the lower end of the first liquid supply pipe 23 extends to liquid storage
It is connected in part 28 and with liquid storage cylinder 281, the second tobacco juice runner 130 is made of the inner cavity of the first liquid supply pipe 23, booster body 26
Pressure output end be connected in liquid storage piece 28 and be connected with liquid storage cylinder 281, can equally realize defeated to the inside of liquid storage cylinder 281
Enter the effect of pressure.
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, liquid storage cylinder 281 are independently arranged at the outside of atomizer 10 so that atomizer 10
On heating structure 138 be not immersed in liquid storage cylinder 281, only when user using when just by booster body 26 tobacco juice is pumped into
It is contacted in the atomization chamber 110 of atomizer 10 and then with heating structure 138, avoids heating structure 138 because long period of soaking is in cigarette
In liquid and there is a situation where going bad, it ensure that the mouthfeel of sucking of user, improve the usage experience of user.
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.
