Abstract

An electronic cigarette comprises a main rod body with one end thereof being provided with a suction nozzle and the other end being internally provided with a battery, a one-way valve is provided in the main rod body for providing a gas passage when inhaling gas and shutting off the gas passage The one-way valve comprises a valve seat with two penetrating ends, and a valve core and a valve flap mounted inside the valve seat; the valve seat or the valve core is provided with a gas guide hole; and the valve flap is affixed to an orifice at one end of the gas guide hole and generates elastic deformation corresponding to the operation of inhaling or exhaling gas so as to control the open or closed state of the gas guide hole.

First claim

What is claimed is:

1. An electronic cigarette, comprising:
a main rod body, one end of the main rod body disposing a suction nozzle, and the other end of the main rod body disposing a battery; and
a one-way valve disposed in the main rod body and configured to communicate an air path when inhalation and block the air path when blowing, the one-way valve being located between the suction nozzle and the battery;
wherein the one-way valve comprises a valve seat with both ends throughout, a valve core and a valve flap installed in the valve seat, the valve seat or the valve core defines a gas guide hole therein; the valve flap is attached at a port of one end of the gas guide hole and used to control open and close state of the gas guide hole according to corresponding elastic deformation generated by inhalation or blowing operations;
the valve flap is disposed on the valve core or the valve seat, and comprises a sheet body and a connecting portion; the valve flap is thin-sheet shaped with an area larger than the gas guide hole to completely cover the port of one end of the gas guide hole; the connecting portion is located at one side edge of the sheet body;
the valve flap is connected to the valve seat, and the gas guide hole is defined in the valve core, one side of the valve seat defines a valve core-accommodating groove matching with an outer contour of the valve core, the valve core is embedded in the valve core-accommodating groove, the valve flap is attached on an outer surface of the valve core and covers the gas guide hole, whereby airflow flows from the valve seat toward the valve core, the valve flap is firmly attached on an outside of the port of one end of the gas guide hole under the airflow pressure, then the gas guide hole is closed and the air path is blocked; while airflow flows from the valve core toward the valve seat, the valve flap generates elastic deformation under the airflow pressure, and the sheet body moves away from the gas guide hole, then finally achieves the communication of the air path; or
the valve flap is connected to the valve core, and the gas guide hole is defined in the valve seat, one side of the valve seat defines a valve core-accommodating groove matching with the outer contour of the valve core, the valve core is embedded in the valve core-accommodating groove, the valve flap locates at one side of the valve core near to the valve seat and is attached on an inner surface of the valve core-accommodating groove and completely covers the port of one side of the gas guide hole, whereby airflow flows from the valve core toward the valve seat, the valve flap is firmly attached on an outside of the port of one end of the gas guide hole under the airflow pressure, then the gas guide hole is closed and the air path is blocked, while airflow flows from the valve seat toward the valve core, the valve flap generates elastic deformation under the airflow pressure, and the sheet body separates from the valve seat and moves away from the gas guide hole, then finally achieves the communication of the air path.

2. According to the electronic cigarette in claim 1 , wherein the valve flap is integrally formed with the valve core or the valve seat; or
the valve flap is separately arranged, and the connecting portion of the valve flap is firmly fixed between the valve seat and the valve core by a connection method.

3. According to the electronic cigarette in claim 1 , wherein the valve flap is made of soft plastic material.

4. According to the electronic cigarette in claim 1 , wherein one end of the main rod body near the suction nozzle further disposes an atomization device electrically connecting with the battery.

5. According to the electronic cigarette in claim 4 , wherein the one-way valve is disposed between the suction nozzle and the atomization device.

6. According to the electronic cigarette in claim 4 , wherein the one-way valve is disposed between the battery and the atomization device, and one end of the valve seat near the battery disposes vent hole along radial direction communicating with the gas guide hole.

7. According to the electronic cigarette in claim 6 , wherein the atomization device disposes a heating wire used to vaporize the e-liquid, the valve seat and the valve core disposes threading hole for the two ends of the heating wire passing through.

8. According to the electronic cigarette in claim 4 , wherein the electronic cigarette further includes an atomization control unit electrically connecting with the battery to control the power-on or power-off for the atomization device, the atomization control unit comprises an atomization control circuit and an atomization control switch which is connected with the atomization control circuit.

9. According to the electronic cigarette in claim 8 , wherein the atomization control switch is a capacitive sensor switch or an airflow sensor switch.

10. According to the electronic cigarette in claim 1 , wherein the other end of the electronic cigarette away from the suction nozzle disposes a light-emitting device, the light-emitting device comprises a light-emitting unit electrically connecting with the battery and a light cap covering the outer of the light-emitting unit.

11. According to the electronic cigarette in claim 10 , wherein at the connection between the light cap and the main rod body disposes an air inlet communicating with the gas guide hole.

12. According to the electronic cigarette in claim 1 , wherein on the sidewall of the main rod body corresponding to the battery near one end of the suction nozzle disposes an air inlet communicating with the gas guide hole.

13. An electronic cigarette device, comprising:
an electronic cigarette box; and
an electronic cigarette accommodated in the electronic cigarette box, the electronic cigarette comprising:
a main rod body, one end of the main rod body disposing a suction nozzle, and the other end of the main rod body disposing a battery; and
a one-way valve disposed in the main rod body and used to communicate an air path when inhalation and block the air path when blowing, the one-way valve being located between the suction nozzle and the battery;
wherein the one-way valve comprises a valve seat with both ends throughout, a valve core and a valve flap installed in the valve seat, the valve seat or the valve core defines a gas guide hole therein; the valve flap is attached at a port of one end of the gas guide hole and used to control open and close state of the gas guide hole according to corresponding elastic deformation generated by inhalation or blowing operations;

the valve flap is disposed on the valve core or the valve seat, and comprises a sheet body and a connecting portion; the valve flap is thin-sheet shaped with an area larger than the gas guide hole to completely cover the port of one end of the gas guide hole; the connecting portion is located at one side edge of the sheet body;
