Abstract

An electronic cigarette atomization device includes an atomization bushing, an electric heater coil and an atomization base located in the atomization bushing. The atomization device further includes a liquid supply component inserted into the atomization bushing; the liquid supply component is formed by high temperature resistant fiber free of glass fiber and, a through hole axially extended is defined in the middle portion of the liquid supply component; and the electric heater coil is positioned in the through hole of the liquid supply component and is pressed against an inner wall of the liquid supply component. The liquid supply component of the atomization device is made of high temperature resistant fiber material free of glass fiber, thus making the construction and process simplified, leading to low fabrication cost, and causing no damage to human body.

First claim

What is claimed is:

An electronic cigarette atomization device, comprising an atomization bushing, an electric heater coil and an atomization base located in the atomization bushing, wherein the atomization device further comprises a liquid supply component inserted into the atomization bushing; the liquid supply component is formed by high temperature resistant fiber free of glass fiber and, a through hole axially extended is defined in the middle portion of the liquid supply component; and the electric heater coil is positioned in the through hole of the liquid supply component and is pressed against an inner wall of the liquid supply component;
wherein a first and second wire guiding holes for passing through two ends of the electric heater coil are defined axially in the atomization base; and
a first end of the electric heater coil passes through the through hole along a direction toward the atomization base and then passes through the first wire guiding hole; and the second end thereof passes through the through hole along a direction toward an atomization case; the second end is bent and passes through the second wire guiding hole via the outer wall of the liquid supply component.

2. The electronic cigarette atomization device as recited in claim 1 , wherein the liquid supply component is made of any one of the following fiber materials: non-woven fabrics, wood pulp fiber, chemical fiber, or polyvinyl alcohol.

3. The electronic cigarette atomization device as recited in claim 1 , wherein the electric heater coil is a hollow spiral tube and is axially disposed in the through hole.

4. The electronic cigarette atomization device as recited in claim 1 , wherein the middle portion of the electric heater coil is bent many times in turn such that fence construction with arcuation conformable to internal contour of the through hole is formed for sufficiently contacting the inner wall of liquid supply component.

5. The electronic cigarette atomization device as recited in claim 1 , wherein the atomization base is secured at one end of the liquid supply component; the atomization device further includes an atomization case disposed at the other end of the liquid supply component distanced away from the atomization base for engaging the atomization base to sealably secure the component in the atomization case of the atomization bushing; and the atomization base and atomization case have a first and second venting holes respectively defined at their middle portions and communicating with the through hole.

6. An electronic cigarette comprising an atomization device and a battery connected electrically to the atomization device so as to supply power to the same, wherein the atomization device is the one as recited in claim 1 ; and the battery is disposed on the atomization base at one side away from the liquid supply component.

7. The electronic cigarette as recited in claim 6 , wherein a first electrode component is disposed between the atomization base and battery; the first electrode component includes a first base body, a first post received in the middle portion of the first base body, and a first insulation bushing located between the first base body and first post; and the first base body and first post are coupled with both ends of the electric heater coil so as to form the positive and negative electrodes of the atomization device.

8. The electronic cigarette as recited in claim 7 , wherein a second electrode component matched and connected with the first electrode component is disposed on the battery at a side opposite to the first electrode component; the second electrode component includes a second base body, a second post received in the middle portion of the second base body, and a first insulation bushing located between the second base body and second post; and the second base body and second post are coupled with the positive and negative electrodes of the battery.

9. The electronic cigarette as recited in claim 8 , wherein the electronic cigarette includes an absorption stem and a battery stem connected with the absorption stem; the absorption and battery are detachably connected with each other; and the absorption stem and battery stem have a first and second connection portions at their corresponding ends respectively for realizing stable connection between two stems.

10. The electronic cigarette as recited in claim 9 , wherein the atomization bushing is the absorption stem; the first base body is disposed on the atomization bushing at an end connected with the battery and forms the first connection portion; and the second base body is located on the battery stem at an end connected with the absorption stem and forms the second connection portion.

11. The electronic cigarette as recited in claim 6 , wherein the electronic cigarette further includes an atomization control unit electrically coupled with the battery so as to provide power to the atomization device or shut off power provided to the atomization device; the atomization control unit is positioned between the atomization base and battery; alternatively, it is positioned on the battery at a side far away from the atomization base.

12. The electronic cigarette as recited in claim 11 , wherein the atomization control unit includes an atomization control circuit and an atomization control switch connected to the atomization control circuit; the atomization control switch is a capacitive sensor switch, gas flow sensor switch, or button switch; the atomization control circuit is integrated into the atomization control switch; alternatively, the atomization control unit also includes an atomization control circuit board connected to both of the battery and atomization control switch; and the atomization control circuit is integrated into the atomization control circuit board.

13. An electronic cigarette device comprising an electronic cigar case and electronic cigarette contained in the cigar case, wherein the electronic cigarette is the one as recited in claim 6 .
