Abstract

Disclosed is an electronic cigarette, comprising a suction stem (10) and a power supply rod (20), wherein the suction stem (10) comprises a suction cylinder (11), and an end of the suction stem (10) is provided with a suction nozzle cover (13). The electronic cigarette further comprises a gas valve (16). By the means of the gas valve (16), the electronic cigarette will not be smoked once it is brought into the mouth of a person, effectively preventing children and infants from sucking the electronic cigarette as a toy.

Claims

1. An electronic cigarette, defining a gas passage for smoking, the electronic cigarette is provided with a gas valve for switching the gas passage.

2. The electronic cigarette according to claim 1, wherein the gas valve is set in the suction nozzle cover for switching on or off the suction nozzle cover.

3. The electronic cigarette according to claim 2, wherein the gas valve comprises a bottom seat and columns disposed at a first side of the bottom seat, the columns are spaced therefrom to form a ventilation groove for aerosol flowing, a bottom of the ventilation groove is formed by a part area of the first side;

there are two columns, and the cross-section of the columns is arcuate, and the two columns are provided with two planar surfaces opposite to one another and symmetrical disposed.

4. The electronic cigarette according to claim 2, wherein the gas valve comprises a bottom seat and a column disposed at a first side of the bottom seat, the column axially defines a cavity therein, a distal end of the column radially defines an air vent therein;

the air vent communicates with the aerosol passage in the suction stem and the cavity, the first side of the bottom seat defines a groove therein, the groove is formed by the cavity extending from the first side toward a second side of the bottom seat, and the groove communicates the cavity with outside.

5. The electronic cigarette according to claim 4, wherein a wall of the suction hole of the suction nozzle cover extends inward to form a sidewall, the sidewall of the suction hole blocks the air vent when pulling out the gas valve, or exposes the air vent when pressing the gas valve.

6. The electronic cigarette according to claim 3 or claim 4, wherein a distal end of the column extends outward to form a stopping part capable of preventing the gas valve escaping from the through-hole of the suction nozzle cover.

7. The electronic cigarette according to claim 3 or claim 4, wherein the bottom seat is truncated cone-shaped, and a diameter of the first side opposite to the suction nozzle cover is smaller than a diameter of the second side.

8. The electronic cigarette according to claim 1, wherein the suction stem further comprises a first connector disposed at the other end of a suction cylinder of the suction stem and connected with the power supply rod.

9. The electronic cigarette according to claim 8, wherein the power supply rod comprises a battery tube and a battery disposed in the battery tube;

one end of the battery tube disposes a second connector coupled to the first connector, the other end of the battery tube is provided with a switch module and a light cap assembly;

both the first connector and the second connector comprises an outer electrode ring, an insulation ring and an inner electrode in turn nested.

10. The electronic cigarette according to claim 9, wherein the suction stem comprising an atomizer disposed in the suction cylinder operable to produce aerosol;

the atomizer comprises an atomization chamber formed in a liquid-storage piece sleeved on a catheter, and two ends are sealed, and a heater disposed in the atomization chamber;

two ends of the atomization chamber are sealed by a liquid-blocking seat and the outer electrode ring respectively.

11. The electronic cigarette according to claim 10, wherein the heater comprises a liquid-guiding piece of which two ends extend out of an outer sidewall of the catheter and mutually abuts with the liquid-storage piece, and a heating wire winding on an outer surface of the liquid-storage piece;

two ends of the heating wire are electrically connected to the inner electrode and the outer electrode ring respectively.

12. The electronic cigarette according to claim 2, wherein the gas valve is rotatably fitted to the suction nozzle cover, the suction nozzle cover comprises a bottom wall and an annular side wall longitudinally extending from a periphery of the bottom wall, the bottom wall defines the suction hole;

the gas valve comprises a bottom cover and an annular side wall longitudinally extending from a periphery of the bottom cover, and the bottom cover defines a via hole selectably connected with the suction hole.

13. The electronic cigarette according to claim 12, wherein the bottom wall of the suction nozzle cover racially extends outwards to form an annular mounting flange;

the gas valve defines an annular groove in its side wall inner; and

the annular mounting flange is fitted in the annular groove.

14. The electronic cigarette according to claim 13, wherein the side wall of the suction nozzle cover forms a mounting step;

and a distal end of the side wall of the gas valve rests on the mounting step.

15. The electronic cigarette according to claim 2, the gas valve comprises a sealing stopper inserted in the suction nozzle cover and a valve cover flexibly connected with the sealing stopper;

the sealing stopper defines a smoke outlet communicated with an inner of the suction nozzle cover; and

the valve cover comprises a flexible connection flexibly engaged with the sealing stopper, a lip connected with the flexible connection, and a sealing column formed on the lip for tightly inserted in the smoke outlet.

16. The electronic cigarette according to claim 1, wherein the power supply rod comprises a first power cylinder with the battery therein and a second power cylinder slidably sleeved with the first power cylinder, and the gas valve is set between the two power cylinders.

17. The electronic cigarette according to claim 16, wherein the gas valve comprises a valve plug disposed in an inner wall of the first power cylinder and a sealing sheath disposed in an inner wall of the second power cylinder.

18. The electronic cigarette according to claim 17, wherein the valve plug comprises an inserting portion fixed in the inner wall of the first power cylinder and a sliding column extending from one end of the inserting portion and axially towards the second power cylinder;

the sliding column therein defines a cavity communicated with an inner of the inserting portion; and

a side wall of the sliding column defines a vent hole communicated with the cavity.

19. The electronic cigarette according to claim 18, wherein the sealing sheath is sleeved on the sliding column;

when the second power cylinder is departed from the first power cylinder, the sealing sheath completely seals off the vent hole in the sliding column.

20. The electronic cigarette according to claim 19, wherein an end of the sliding column is sleeved with a stopping ring to prevent the sealing sheath sliding off the sliding column.
