Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to field of electronic cigarette and more particularly, relates to an electronic cigarette having an organic cotton liquid guiding member. 
       BACKGROUND OF THE INVENTION 
       [0002]    A prior art electronic cigarette includes a liquid storage member for storage of cigar liquid, an atomization device for converting cigar liquid inside the liquid storage member into smoke, and a power supply device for providing power to the atomization device. The atomization device is generally composed of an electronic heater coil, a liquid guiding member, and a smoke guiding tube with a through hole for flowing of smoke. The liquid guiding member and smoke guiding tube are both made of glass fiber containing silicon dioxide. The glass fiber belongs to inorganic cotton. The electronic heater coil is enwound on the liquid guiding member, and both ends thereof are connected with electric wire. After that, the electric heater coil is transversely disposed inside the smoke guiding tube. Next, the exposed ends of the electric wire are connected to the positive and negative electrodes of the power supply device. The liquid guiding member is connected to the liquid storage member so as to absorb cigar liquid. Finally, the cigar liquid is transferred to the electric heater coil through the liquid guiding member. When the electric heater coil is powered, smoke will be atomized to generate smoke. As the liquid guiding member and smoke guiding tube of the atomization device are constructed of inorganic cotton formed by a great number of tiny glass fibers enwound together, they are susceptible to breaking, bending and twisting. When the electric heater coil is enwound on the liquid guiding member or secured into the smoke guiding tube, the liquid guiding member or smoke guiding tube will be bent or twisted. During this process, a great deal of glass fiber floccules will stick onto the liquid guiding member or inner wall of the smoke guiding tube. When such an electronic cigarette is assembled completely and used, these floccules will easily enter into mouth, respiratory tract or lung of a person, thus resulting in damage to body health. In addition, the smoke guiding tube constructed of glass fiber is easily broken, bent or twisted, thereby having weak structural stability.

Both of the supporting tube and external casing are provided with a through hole and the through holes are communicated with each other thus constituting a venting hole of the main guiding tube. 
         [0011]    Here, one end of the external casing connected to the atomization base is provided with a second holding groove engaged with the first holding groove of the internal casing. 
         [0012]    Here, the second holding groove is an opened groove radially outwardly extended through the side wall of the external casing and having a notch defined in an end portion of the external casing. 
         [0013]    Here, the two ends of the liquid guiding member extend out of the external casing, bent, and are pressed against the outer wall of the internal casing so as to be pressed against the liquid storage component. 
         [0014]    Here, a permeating component constructed of organic material and with resiliency is disposed between the main guiding tube and liquid storage component.

         [0019]    Using above technical solution, the present invention can gain following advantageous effects. In the present invention, by changing structure of the atomization device, and making the liquid guiding member, liquid storage component and permeating component with organic cotton, there is no need to use inorganic cotton material such as glass fiber, thus reducing cost, improving production efficiency, and most importantly preventing damage caused to human body by inhaling of glass fiber floccules. In addition, by replacement of smoke guiding tube made of glass fiber with smoke guiding tube made of plastic, silica gel, metal or ceramic with higher hardness, damage to human body caused by inhaling of glass fiber floccules by the smoker is eliminated effectively. Moreover, the smoke guiding tube is composed of a main guiding tube having the external casing an integral casing. One of the external casing and the internal casing is inserted into the other one so as to mount and secure the liquid guiding member and accordingly, mounting and use of the liquid guiding member is more stable. Due to rapid liquid guiding characteristics of organic cotton material, the temperature of the electric heater coil is decreased, thus ensuring reliability of the electric heater coil in use. In addition, the smoke guiding tube or is made from plastic, silica gel, metal or ceramic and therefore, strength of the smoke guiding tube is guaranteed, and the entire electronic cigarette has stable internal construction and is safe.

The atomization base  24  is pressed against and held on the inner wall of the outer sleeve  1  by its outer side wall. It is made of plastic or metal for ensuring strength and no glass fiber floccules will be generated. 
         [0032]    As shown in  FIGS. 6 and 7 , the main guiding tube  35  includes a supporting tube  351  and an external casing  352  which communicate with each other. The supporting tube  351  and external casing  352  are integrally formed or constructed separately. Both of the supporting tube  351  and external casing  352  are provided with a through hole, and these through holes communicate each other thus forming a venting hole  353  of the main guiding tube  35 . The external casing  352  is provided with a second holding groove  354  engaged with the first holding groove  244  of the internal casing  241 . The second holding groove  354  is an opened groove radially outwardly extended through the side wall of the external casing  352  and having a notch defined in an end portion of the external casing  352 . The liquid guiding member  212  held in the first holding groove  244  passes through the second holding groove  354  and is pressed against the liquid storage component  37  so as to absorb cigar liquid to be atomized by the electric heater coil  211 . 
         [0033]    As shown in  FIGS. 2 and 3 , the liquid storage component  37  is intended for absorbing and storing cigar liquid to be further atomized by the atomizer  2 . The liquid storage component  37  has the ability of absorbing and storing cigar liquid, and may be made from material with the ability of absorbing and storing liquid for example cotton material. The liquid storage component is of a hollow cylindrical construction, is sleeved on the outside of the main guiding tube  35 , and is pressed against and supported by the outer wall of the main guiding tube  35 . The two ends of the liquid storage component  37  are inserted into a circular cavity of the atomization base  24  and that of the nozzle case  41  respectively. The side wall of the liquid storage component  37  is pressed against the liquid guiding member  212 . Cigar liquid soaks from the liquid storage component  37  into the liquid guiding member  212 , is absorbed, and evaporated by the electric heater coil  211  to generate smoke. 
         [0034]    As shown in  FIGS. 2 and 3 , the electronic cigarette  100  further includes a permeating component  38  capable of absorbing and storing cigar liquid, and may be constructed of non glass fiber material with the ability of absorbing and storing liquid for example organic cotton material. The organic cotton material may be pure cotton, hard paper, chemical fiber containing mainly organic material, or twine. The permeating component  38  may be made from any one of above material. Or, it may be made from the combination of any two or more of the above material. The permeating component  38  is located between the liquid storage component  37  and the main guiding tube  35 . The outer wall and inner wall of the permeating component  38  are pressed against the inner wall of the liquid storage component  37  and outer wall of the external casing  352  of the main guiding tube  35  respectively. The permeating component  38  is sleeved on the outside of the smoke guiding tube or, it may be enwound on the outer side of the smoke guiding tube such that the inner wall of the permeating component  38  is pressed against the two ends of the liquid guiding member  212  in order that the liquid guiding member  212  absorbs the cigar liquid soaking from the liquid storage component  37  into the permeating component  38 . The liquid absorption ability of the permeating component  38  may be slightly great than the liquid storage component  37  so that the cigar liquid will soak and be transported to the liquid guiding member  212  from the liquid storage component  37  more rapidly. 
         [0035]    As shown in  FIG. 3 , in present embodiment, the nozzle case  41 , atomization base  24 , main guiding tube  35 , liquid storage component  37 , and part of the side wall of the outer sleeve  1  of the electronic cigarette collectively define a space for storage of cigar liquid which functions as a cigar liquid cup of a traditional electronic cigarette.
