Description

    FIELD OF THE INVENTION
  • The present invention relates to an electronic cigarette atomizer, and more particularly to a dual-tube electronic cigarette atomizer.
  • BACKGROUND OF THE INVENTION
  • Today when “smoking is harmful to your health” has become a common sense, there are one billion people smoking cigarettes, and this figure is still rising. On Mar. 1, 2003, the World Health Organization (WHO) issued the first international smoking ban—Framework Convention on Tobacco Control. According to WHO's data, smoking causes 4,900,000 deaths each year. Smoking causes serious respiratory system diseases and cancers, though it is a hard job to persuade the smokers to completely quit smoking.
  • Therefore, electronic cigarettes have become increasingly popular in recent years. Electronic cigarettes emulate tobacco cigarettes, but without the combustion of tobacco during use. Rather than burning tobacco, a fluid is atomized within the electronic cigarette, which emulates the smoke produced in a tobacco cigarette. The fluid may contain flavoring agents such as tobacco flavor, menthol, and others, to enhance the “smoking” experience of the electronic cigarette. Nicotine has been added to the atomization fluid in prior art electronic cigarettes. Since electronic cigarettes are not real cigarettes, they can be enjoyed in designated non-smoking areas, which are becoming increasingly common.
  • Conventionally, the structure of a conventional atomizer of an electronic cigarette is complicated, in which the tube and other components are all separated at the beginning, and they have to be assembled before being used. Furthermore, it has to equip with a threaded metal tube with large size and weight to weld with a heating wire, which increases the complexity of the assembly process. Therefore, there remains a need for a new and improved electronic cigarette atomizer to overcome the problem stated above.
  • SUMMARY OF THE INVENTION
  • It is an object of the present invention to provide an atomizer of an electronic cigarette that is small, light and easy to be assembled with the electronic cigarette.
  • It is another object of the present invention to provide an atomizer of an electronic cigarette wherein users do not have to solder electrodes of the atomizer to the electronic cigarette.
  • It is a further object of the present invention to provide an atomizer of an electronic cigarette wherein inner threads of a double-layered shell body (of the atomizer) are corresponding to threads of an electronic cigarette battery to connect with each other without using a bulky and heavy metal tube.
  • In one embodiment, the atomizer in the present invention has a double-layered shell body, a nozzle cap, an electronic wick, and a contact piece, wherein the double-layered shell body is formed as one piece which includes an outer tube, an inner tube, and an inner layer. The outer tube also has outer threads while the inner tube has inner threads. The inner tube also has a recessed slot, an upper protruding portion and a lower protruding portion.
  • The electronic wick having a wick made by glass fiber, a heating wire, leads, and a filtering rod with a center through hole. The filter rod with a center through hole is used to secure the lead, prevent cooled liquid from moving down, and add more flavored carriers.
  • The contact piece has a wing-shaped elastic piece, an insulating spacer and a rivet, wherein the insulating spacer is used to separate the wing-shaped elastic piece and the rivet.
  • The nozzle cap has an air hole, a nozzle and a threaded structure, which is corresponding to the outer threads of the double-layered shell body. A sealing gasket is disposed in the nozzle cap and used to seal the upper portion of the inner tube of the double-layered shell body.

Nothing herein is to be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention.
  • In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:
  • As shown in FIGS. 1 and 2, an atomizer in the present invention may have a double-layered shell body (11), a nozzle cap (12), an electronic wick (13) and a contact piece (14). The double-layered shell body (11) is designed as one piece with one molding, and has an outer tube (21), an inner tube (22), and an inner layer (23). The inner layer (23) is used for filling electronic tobacco oil. The outer tube (21) has outer threads (24) while the inner tube (22) has inner threads (25). The inner tube (22) also has a recessed slot (26), an upper protruding portion (27) and a lower protruding portion (28).
  • Referring to FIG. 3, the electronic wick (13) has a wick (31) made by glass fiber, a heating wire (32), leads (33) and a filtering rod (34) with a center through hole. The filter rod (34) with a center through hole is used to secure the lead (33), prevent cooled liquid from moving down, and add more flavored carriers.
  • Referring to FIG. 4, the contact piece (14) has a wing-shaped elastic piece (41), an insulating spacer (42) and a rivet (43), wherein the insulating spacer (42) is used to separate the wing-shaped elastic piece (41) and the rivet (43).
