2. Description of the Prior Art
Cigarette is popular in the world, especially amongst men. However, tar in the cigarette is known harmful to human health, in which tens of ingredients are carcinogenic substances. Moreover, passive smoking can be more harmful to non-smokers. Therefore, smoking is prohibited in many public places. However, it remains extremely difficult for a smoker to quit smoking. Therefore, many cigarette substitutes have been proposed, among which the most common one is noncombustible electronic atomization cigarette which is free of tar.
Presently, almost all electronic cigarettes are made in integral structure. The electronic cigarette has a power supply at its front end of and an atomizer at its rear end. While the atomizer of the cigarette is powered by the power supply, an LED lamp of the power supply device is also lightened to simulate a burnt cigarette. A conventional atomizer comprises a glass fiber tube, a glass fiber core, a radiation core, a cotton cloth, and cellucotton. The radiation core located in the interior of the glass fiber tube is wound around the glass fiber core. The cotton cloth wraps the outer wall of the glass fiber tube and presses the exposed end of the glass fiber core in between the cotton cloth and the glass fiber tube. The cotton cloth is wrapped by the cellucotton. An annular room for storing the tobacco liquid is formed between the cotton cloth and the cellucotton. Two wires are welded on the radiation core and drawn through the glass fiber tube to the electrodes of the power supply. An electronic cigarette with such an atomizer is complicated in production and a room therein for storing tobacco oil is very small.

As shown in
Thread bushing 3 can be an inner thread bushing as shown in
The atomization shell 7 is a hollow tube with a sealing sleeve 5 which is a hollow cylinder fixed therein. As shown in
The opening end of the sealing sleeve 5 is muff-coupled to a threadless end of the thread bushing 3. The external diameter of the opening end is matched with the inner diameter of the atomization shell 7 so as to prevent tobacco liquid from flowing out.
An electric heating element 4 is provided between the sealing sleeve 5 and the thread bushing 3. The heating element 4 may be a solenoid heating elements. A second intermediary piece 9 is provided to extend through the solenoid coil of the electric heating element 4. One end 41 of the electric heating element 4 is inserted and clamped in between the thread bushing 3 and the insulation ring 2. The other end 42 of the electric heating element 4 is inserted and clamped in between the insulation ring 2 and the electrode ring 1. In this way, the electric heating element 4 is powered through the thread bushing 3 connected to the cathode of the battery and the electrode ring 1 connected to the anode of the batter.
Then, The opening end of the sealing sleeve 5 is muff-coupled to a threadless end of the thread bushing 3 to make the first intermediary piece 6 abut against the second intermediary piece 9 so that both the intermediary pieces are pressed tightly together. In an embodiment of the invention, the intermediary pieces may use those materials being capable of transporting liquid, such as glass fiber, cotton thread or the like. Thus, the first intermediary piece 6 can transmit the tobacco liquid from the tobacco liquid storage room to the second intermediary piece 9. The tobacco liquid in the second intermediary piece 9 is atomized by the electric heating element 4, enters the aerosol passage 71 through the through hole 10 of the sealing sleeve 5, and is finally inhaled by a smoker.
The mouth-piece 8 is also muff-coupled with the first end 70 of the atomization shell 7. An orifice 12 communicating with the first end 711 of the aerosol passage 71 is provided at the mouth piece 8. The interior of the first end 70 of the atomization shell 7 is closed. Two injection openings 13 are provided opposite to each other around the aerosol passage 71 at the closed end surface of the interior of the first end of the atomization shell 7. Two silicone plugs 14 are provided correspondingly at the mouth-piece 8 for plug in the injection openings 13. Thus, after the tobacco liquid in the tobacco liquid storage room exhausts, the electronic cigarette can be refilled with the tobacco liquid by removing the mouth-piece 8 and injecting the tobacco liquid into the injection openings 13. The mouth-piece 8 is put back after the tobacco liquid is finished so that the electronic cigarette can be used again. There is no limitation on the number of the injection openings 13, whilst in the present embodiment two injection openings 13 are used. In this arrangement, when the tobacco liquid is injected through one opening 13, air in the tobacco liquid storage room can be discharged from the other opening 13.
Although the details of the invention have been described in view of the above illustration, various modifications and variations may be made without departing from the spirit and scope of the invention. It is intended that the scope of the invention is defined by the following claims and their equivalents.
