Reference is made to FIGS. 4-7. The electronic cigarette 100 contains an atomization device 10 and a battery 20. The atomization device 10 works to transform cigar liquid into smoke to be absorbed by a user. The battery 20 is electrically connected with the atomization device 10 so as to power the atomization device 10.
As shown in FIGS. 1-2, the atomization device 10 has an atomization bushing 11, a liquid supply component 12, an electric heater coil 13, an atomization base 14 and an atomization case 15.
The atomization 11 is sleeved on the outer portion of the liquid supply component 12, electric heater coil 13, atomization base 14 and atomization case 15, and provides a cup body for the atomization device 10 for containing and sealing cigar liquid. In this embodiment, the atomization bushing 11 is configured to be a cylindrical tubular construction, and the inside of the bushing 11 is hollow so as to define a receiving cavity for receiving respective internal parts of the atomization device 10. Understandingly, in addition to the cylindrical construction of this embodiment, the atomization bushing 11 may also be configured to have any other tubular construction with a hollow cavity.
The liquid supply component 12 is of a hollow tubular construction matching the atomization bushing 11 and is disposed coaxially with the bushing 11. The liquid supply component 12 is formed with high temperature resistant fiber material free of glass fiber for supporting and holding the electric heater coil 13, and absorbing and storing cigar liquid so that the cigar liquid is atomized later by the electric heater coil 13. In present embodiment, the liquid supply component 12 is particularly made of any one of the fiber materials listed below: non-woven fabrics, wood pulp fiber, chemical fiber, or polyvinyl alcohol.
The liquid supply component 12 has a through hole 121 which is defined in its middle portion and is extended axially. The electric heater coil 13 is received in the through hole 121 of the liquid supply component 12 and is pressed against the inner wall of the liquid supply component 12 such that the electric heater coil 13 will sufficiently contact the cigar liquid.
Referring to FIG. 2, in this embodiment, the middle portion of the electric heater coil 13 functioning to heat and atomize cigar liquid is of a spiral tube configuration and is axially disposed in the through hole 121. The outer diameter of the spiral tube formed at the middle portion of the electric heater coil 13 is slightly larger than the inner diameter of the through hole 121 of the liquid supply component 12. As such, the electric heater coil 13 is supported and held in the through hole 121 by press of the electric heater coil 13 against the inner wall of the liquid supply component 12, and the electric heater coil 13 can sufficiently contact the inner wall of the liquid supply component 12 so that the cigar liquid inside the liquid supply component 12 will contact the electric heater coil 13 thus being atomized by the coil 13 and changed to smoke.
As an embodiment, the middle portion of the electric heater coil 13 for heating and atomizing cigar liquid may be bent repeatedly to form a plane portion which may be bent in entirety again to form arcuation conforming to the internal contour of the through hole 121, and finally a fence sufficiently contacting the inner wall of the liquid supply component 12 is formed.
The atomization base 14 is held at one end of the liquid supply component 12 for supporting and holding the liquid supply component 12 and electric heater coil 13 in the atomization bushing 11.

In this embodiment, the first post 32 is also of a hollow tube shape, and the middle hollow portion thereof is provided with a first intake hole 321 through which external air may enter into the atomization device 10.
Referring to FIGS. 3 and 5, the battery 20 is disposed opposite to the first electrode component 30. A second electrode component 40 is provided on the battery 20 at a side opposite to the first electrode component 30. The second electrode component 40 matches and is connected with the first electrode component 30, thus realizing electrical connection between the battery 20 and atomization device 10.
Specifically, the second electrode component 40 substantially has the same structure as the first electrode component 30, and includes a second base body 41, a second post 42, and a second insulation bushing 43 disposed between the second base body 41 and second post 42 for insulating the second base body 41 from the second post 42.

The second post 4 is also of a hollow tube shape, and the middle portion thereof is provided with a second intake hole 421 communicating the first intake hole 321 for conducting air.
Please refer to FIGS. 2-3 and 5, in this embodiment, one end of the second base body 41 facing the first base body 31 is provided with a holding groove 44 for insertion therein of a corresponding end of the first base body 31, hence holding the first base body 31 in place. One end of the first base body 31 inserted into the second base body 41 is provided with a boss 34. The boss 34 conforms to the internal contour of the holding groove 44 so as to be placed into the holding groove 44. It is understood that as an embodiment, the holding groove 44 may also be defined in the first base body 31, while a corresponding boss 34 is formed on the second base body 41.

Refer to FIGS. 6-7. When the absorption stem 101 and battery stem 102 are configured to have undetachable integral construction, the two ends of the electric heater coil 13 may directly connected with the positive and negative electrodes of the battery 20 without providing the first and second electrode components 30 and 40 between the atomization base 11 and battery 20. Or, there may only be provided with a first electrode component 30 connected to both ends of the electric heater coil 13, and electric connection between the atomization device 10 and battery 20 is achieved by electric connection of the first electrode component 30 to the positive and negative electrodes of the battery 20.
Please refer to FIGS. 4-5. In this embodiment, the absorption stem 101 and battery stem 102 are detachably connected, and the atomization bushing 11 is used as the stem body of the absorption stem 101. The electronic cigarette 100 of the embodiment is described in greater detail.
The corresponding ends of the absorption stem 101 and battery stem 102 are respectively provided with a first connection portion and a second connection portion which are engaged with each other in order that the absorption stem 101 and battery stem 102 are reliably connected together. In present embodiment, the first base body 31 is disposed on the atomization bushing 11 at one end connected to the battery stem 102 and forms the first connection portion. The second base body 41 is disposed on the battery stem 102 at one end connected to the absorption stem 101 and forms the second connection portion. As an embodiment, independent component may also be provided on the corresponding ends of the absorption stem 101 and battery stem 102 so as to form the first and/or second connection portion.
The atomization bushing 11 (that is, the absorption stem 101) may be connected to the battery stem 102 by means of screwing, clasping, insertion, or magnetic adsorption. In this embodiment, the atomization bushing 11 and battery stem 102 are preferably secured together by screwing. Concretely, as shown in FIG. 5, the outer wall of the boss 34 of the first base body is provided with external thread, whereas the inner wall of the holding groove 44 of the second base body is provided with matched internal thread.
As shown in FIGS. 1-7, in this embodiment, the mouthpiece 50 and atomization bushing 11 are separately configured. The mouthpiece 50 includes a nozzle case 51 sleeved on the end portion of the atomization bushing 11 and a suction hole axially defined in the middle portion of the nozzle case 51. As an embodiment, the mouthpiece 50 may be integrally formed with the atomization bushing 11. In present embodiment, the mouthpiece 50 is configured to be a cylindrical construction. It is understood that the mouthpiece 50 may also have tubular construction such as polygon, ellipse and so on. Alternatively, it may also be designed to be a sleeve construction which has predefined taper and of which the diameter is tapered towards the end portion of the mouthpiece 50.
As shown in FIGS. 5 and 7, the electronic cigarette 100 also includes an atomization control unit 60 connected electrically to the battery 20 and atomization device 10 respectively so as to provide power to the device 10 or shut off power supplied to the device 10. The atomization control unit 60 may be disposed between the atomization base 11 and battery 20, or disposed on the battery 20 at a side away from the atomization base 11.

In this embodiment, the atomization control switch is a sensor switch 61 secured in the battery stem 102 by a switch holding base 62. More specifically, the sensor switch 61 is a capacitive sensor switch. When the electronic cigarette 100 is being used by a user, the capacitive sensor switch senses the capacitance change caused by incoming gas flow and then the switch controls the atomization control circuit to switch on a power supply, thus making the electronic cigarette entering into working status. As an embodiment, the sensor switch 61 may also be a gas flow sensor switch. When the user inhales gas by the mouthpiece 50, negative pressure is generated inside the cavity of the electronic cigarette 100 and in turn, the gas flow sensor switch generates pulse signals to control the atomization control circuit to switch on a power supply.
As the sensor switch 61 in itself is precisely fabricated and generally, a dedicated controller is built therein, the atomization control circuit of this embodiment may be directly integrated into the controller of the sensor switch 61. As an implementation manner, the atomization control circuit may also be integrated into an atomization control circuit board separately disposed outside of the sensor switch 61 and electrically connected to both of the sensor switch 61 and battery 20.
As an implementation manner, the atomization control switch may also be a conventional switch of button type. The button switch is electrically connected to the battery 20 through a button control circuit board such that the atomization control circuit is controlled by pressing the buttons, thus realizing switching on and off of the atomization device 10.
Please refer to FIGS. 3-7, a light emitting device is disposed on the electronic cigarette 100 at the other end away from the mouthpiece 50. The light emitting device is used as a working indicator light of the electronic cigarette 100, and includes a light emitting unit electrically connected to the battery 20 and a light cap 70 disposed at a corresponding end of the battery stem 102. The light cap 70 helps to radiate light generated by the light emitting unit. In this embodiment, the light emitting unit is configured to be a red lamp such that when the smoker smokes the electronic cigarette 100, one end of the electronic cigarette 100 away from the mouthpiece 50 will generate red smoke circles like those produced when a cigar is burned, hence enhancing visual effects of the smoker.
Below, one end of the battery 20 electrically connected to the second post 42 is defined as a positive electrode, while the other end thereof electrically connected to the second base body 41 is defined as a negative electrode. In addition, the atomization control switch is configured to be a sensor switch 61. The current flow routing of the electronic cigarette 100 is described in detail.
When the smoker smokes the electronic cigarette 100, the sensor switch 61 will sense and switch on the atomization control circuit. The detailed current flowing path is as below: the current arrives at the second post 42 from the positive electrode of the battery 20, then travels to the positive electrode of the electric heater coil 121 via the first post 32, next flows to the first base body 31 via the negative electrode of the electric heater coil 121 and finally, comes back to the negative electrode of the battery 20 through the second base body 41.
Understandingly, the electronic cigarette 100 is not limited to the embodiments shown in FIGS. 1-7. Rather, individual features of these embodiments may be combined with each other to form new embodiments.
As shown in FIG. 8, the electronic cigarette 100 is in general contained in the electronic cigar case 200. The cigar case 200 includes a bottom box 81 for containing therein the electronic cigarette 100 and a case lid 82 covered on the bottom box 81. The bottom box 81 is of a square enclosure and of course, it is not limited to square. Rather, it may also take on circle, ellipse, polygon and the like so long as the case lid 82 will match it when the case lid 82 is installed.
Though various embodiments of the invention have been illustrated above, a person of ordinary skill in the art will understand that, variations and improvements made upon the illustrative embodiments fall within the scope of the invention, and the scope of the invention is only limited by the accompanying claims and their equivalents.
