Abstract

An electronic cigarette has a power device (1), a sensor (2), an atomizing core component and a liquid storage component (3). The atomizing core component includes an electric heater (5) and a liquid permeating component (6). The electric heater (5) has a through hole (51), the liquid storage component (3) has a channel (31), and the sensor (2) is connected with the through hole (51) and the channel (31) to form an airflow loop by the auxiliary air inlet. The liquid permeating component (6) is directly sleeved on the electric heater (5), so that the cigarette can adequately heat gasified smoke with uniform small drops. The electric heater (5) and the liquid storage component (3) are connected with the through hole (51) and the channel (31), so that the vapor generated by the atomizing process can be cooled.

Claims

1. An electronic cigarette, comprising:

a housing;

a battery, and a liquid storage component containing liquid, within the housing;

a wire coil electrically connectable to the battery for atomizing liquid from the liquid storage component, with the wire coil surrounded by the liquid storage component;

a channel extending through and surrounded by the liquid storage component, with the channel having a substantially uniform diameter between the wire coil and an inhalation port, and the wire coil having a diameter less than the channel, and

the channel and the inhalation port forming an airflow path within the housing, with the channel providing a continuous passageway from the wire coil to the inhalation port.

2. The electronic cigarette of claim 1 further including a liquid permeating component sleeved on the wire coil, with an outside surface of the liquid permeating component in contact with the liquid storage component and an inside surface of the liquid permeating component in contact with the wire coil.

3. The electronic cigarette of claim 2 with the liquid permeating component longer than the wire coil.

4. The electronic cigarette of claim 1 with the channel having internal surfaces wetted via the liquid, for cooling vapor flowing through the channel.

5. The electronic cigarette of claim 2 further including a liquid conduction component in contact with the liquid permeating component and the liquid storage component.

6. The electronic cigarette of claim 2 further comprising a liquid conduction component in contact with the liquid storage component and the liquid permeating component.

7. The electronic cigarette of claim 1 with the airflow path centrally located within the housing.

8. The electronic cigarette of claim 1 with the liquid storage component including a fiber material.

9. The electronic cigarette of claim 1 with the liquid storage component comprising an elongated cylinder having an annular cross section.

10. An electronic cigarette, comprising:

a housing having an inhalation port;

a battery and a liquid storage component within the housing with the liquid storage holding a liquid;

an electric heater in the housing connectable to the battery for creating vapor from liquid provided from the liquid storage component; and

the liquid storage component having a channel with surfaces wetted via the liquid, and with the channel providing a continuous passageway from the electric heater to the inhalation port.

11. The electronic cigarette of claim 10 with the electric heater comprising a wire coil surrounded by the liquid storage component.

12. The electronic cigarette of claim 10 with the electric heater comprising a wire coil and the channel having a substantially uniform diameter between the inhalation port and the wire coil, and with the wire coil having a diameter less than the diameter of the channel.

13. The electronic cigarette of claim 11 further including a liquid permeating component sleeved on the wire coil, with an outside surface of the liquid permeating component in contact with the liquid storage component and an inside surface of the liquid permeating component in contact with the wire coil.

14. The electronic cigarette of claim 13 with the liquid permeating component longer than the wire coil.

15. The electronic cigarette of claim 10 with the wetted internal surfaces of the channel cooling vapor flowing through the channel.

16. The electronic cigarette of claim 13 further including a liquid conduction component in contact with the liquid permeating component and the liquid storage component.

17. An electronic cigarette, comprising:

a housing;

a battery and a liquid storage component within the housing;

an electric heater electrically connectable to the battery for atomizing liquid from the liquid storage component;

a channel extending through and surrounded by the liquid storage component, with the channel and an inhalation port forming an airflow path within the housing, and with the channel providing a continuous passageway from the electric heater to the inhalation port; and

a liquid permeating component sleeved on the electric heater, with an outside surface of the liquid permeating component in contact with the liquid storage component and an inside surface of the liquid permeating component in contact with the electric heater.

18. The electronic cigarette of claim 17 with the liquid permeating component longer than the electric heater.

19. The electronic cigarette of claim 17 with the heater comprising a wire coil and the channel having a substantially uniform diameter between the wire coil and the inhalation port, and the wire coil having a diameter less than the channel.

20. The electronic cigarette of claim 17 further including a liquid conduction component in contact with the liquid permeating component and the liquid storage component.
