     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0029]    In order to make the propose, the technical solution and the advantage of the present invention more clearly, the present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be understood that, the specific embodiments described herein are only for explaining the present invention, and is not intended to limit the present invention. 
         [0030]    As shown in  FIGS. 2 to 4 , the present invention relates to an electronic cigarette, which comprises a nozzle  1 , a plurality of particles is attached to one end of the electronic cigarette, and the end is far away from the nozzle  1 . 
         [0031]    Specifically, the configuration of the end of the electronic cigarette is various. For example 1, a lamp cap  2  is positioned at the end of the electronic cigarette, and the particles are attached to the end face and/or the peripheral face of the lamp cap  2  (as shown in  FIG. 2  and  FIG. 3 ). For example 2, a battery cover  4  is positioned at the end of the electronic cigarette, and the particles are attached to the end face and/or the peripheral face of the battery cover  4  (as shown in  FIG. 4 ). For example 3, an outside of the electronic cigarette is covered with a protective sleeve, an end cover of the protective sleeve is at the end of the electronic cigarette, and the particles are attached to the end face and/or the peripheral face of the end cover of the protective sleeve. 
         [0032]    The nozzle  1  of the present invention may be an independent nozzle  1 (as shown in  FIG. 4 ), or a nozzle  1  integrated with the electronic cigarette (as shown in  FIG. 3 ). 
         [0033]    The particles  3  are one or more kinds of the carbon particles, plastic particles, glass particles, wooden particles or the metal particles. It can be understood that, there is no limitation to the types of the particles  3 , and different particles can be altered based on the different needs. The carbon particles, plastic particles, glass particles, wooden particles or metal particles are in the shape of granular, so that they are similar to the shapes of the real tobacco leaf and the tobacco shred. In order to make it more realistic, the particles can be the real tobacco leaf. 
         [0034]    It can be understood that, the lamp cap  2 , the battery cover  4  and the end cover can be a plastic part or a glass part. When there is a lamp body mounted inside the electronic cigarette, the lamp cap  2 , the battery cover  4  and the end cover can be transparent, or at least the end of the cap  2  or the battery cover  4  is transparent, so that the light emitted from the lamp body of the electronic cigarette can be shot out from the lamp cap  2 , the battery cover  4  or the end cover, so as to form a vivid smoking effect, that is, the glowing effect of burning the tobacco leaf. 
         [0035]    Meanwhile, when there is no lamp body mounted inside the electronic cigarette, the battery cover  4  and the end cover can be opaque, and the particles are only attached to the end of the battery cover  4  and the end cover, so that the end which is far away from the nozzle  1  of the electronic cigarette is similar to the shape of the real cigarette. 
         [0036]    Particularly, when a lamp body is mounted inside the electronic cigarette, if the particles are the carbon particles and the plastic particles, they are similar in the color to the real tobacco leaf and the tobacco shred, and are closer to the glowing effect of burning tobacco leaf in the real smoking In comparisons, if the particles are the metal particles and the glass particles, the light can be spread all around due to the different degrees of reflection on the surfaces of the glass and the metal, so that the glowing effect is better during the simulation of smoking 
         [0037]    The connection method between the particles  3  and the lamp cap  2 , the battery cover  4  or the end cover is various, and described in detail as follow: 
       Embodiment 1   
       [0038]    An adhesive layer is positioned between the particles  3  and the lamp cap  2 , the battery cover  4  or the end cover. And the particles  3  are adhered to the lamp cap  2 , the battery cover or the end cover through the adhesive layer. The adhesive layer may be the glue, double-sided adhesive tape or the resin adhesive, etc. coated on the lamp cap  2 , the battery cover  4  or the end cover. When the lamp cap  2 , the battery cover or the end cover is a plastic part and the particles  3  are the carbon particles or the plastic particles, the adhesive joint method is preferably used. 
       Embodiment 2 
       [0039]    The particles  3  are dissolved on the lamp cap  2 , the battery cover  4  or the end cover. The dissolve method may be that, firstly coat the lamp cap  2 , the battery  4  or the end cover with dissolve agents, and then the particles  3  are dissolved together with the lamp cap  2 , the battery cover  4  or the end cover in the function of the dissolve agents. 
       Embodiment 3 
       [0040]    The particles  3  are fused on the lamp cap  2 , the battery cover  4  or the end cover. The fusing method is hot melting, that is, firstly, local heating the position which needs to be coated with the particles  3  on the lamp cap  2 , the battery cover  4  or the end cover, and then the particles  3  are adhered to the lamp cap  2 , the battery cover  4  or the end cover. 
       Embodiment 4 
       [0041]    The particles  3  are embedded in the lamp cap  2 , battery cover  4  or the end cover. That is, a plurality of holes for embedding the particles  3  are defined in the lamp cap  2 , the battery cover  4  or the end cover, while the particles  3  are in the shapes to match the holes. The particles  3  are embedded in the lamp cap  2 , the battery cover  4  or the end cover in the way of interference fit or snap fit. Absolutely, there are many other embedding methods. 
       Embodiment 5 
       [0042]    The lamp cap  2  is connected with the particles  3  in the way of magnetic suction. Specifically, the lamp cap  2 , battery cover  4  or the end cover is magnetic substance, and the particles are also the magnetic substances. That is, the inside of the lamp cap  2 , the battery cover  4  or the end cover is mixed with magnetic powders, or the outside of the lamp cap  2 , the battery cover  4  or the end cover is coated with magnetic powders. Besides, the outsides of the particles  3  are coated with magnetic powders or the insides are mixed with magnetic powders. Therefore, the lamp cap  2 , the battery cover  4  or the end cover is magnetic, and the particles are also magnetic, so that the lamp cap  2 , the battery cover  4  or the end cover is connected with the particles  3  in the way of magnetic suction. It can be understood that, not only by adding the magnetic powders can make the lamp cap  2 , the battery cover  4  or the end cover magnetic, but also in other ways, for example, by embedding a magnet inside the lamp cap  2 , battery cover  4  or the end cover, and embedding magnets inside the particles. 
       Embodiment 6 
       [0043]    An external surface of the end away from the battery rod  1  of the lamp cap  2 , the battery cover  4  or the end cover is covered with an outer coat film. The outer coat film outwardly forms a plurality of cystidiums for containing the particles  3 , and the particles  3  are positioned within the cystidiums. It can be understood that, when using the method of film coating, the outer coat film may be made of transparent materials. The outer coat film is adhered to the lamp cap  2 , the battery cover  4  or the end cover (not shown in the figures). 
         [0044]    The shapes of the particles  3  are irregularly, they may be one or more kinds of the sphere, cylinder, cone, prism or polyhedron. 
         [0045]    Preferably, the volumes of the particles  3  range from 1.5 mm 3  to 150 mm 3 . 
         [0046]    The arrangements of the particles  3  are irregularly. Preferably, the distance between two adjacent particles  3  ranges from 0.5 mm to 3 mm. 
         [0047]    In conclusion, for the electronic cigarette in the present invention, a plurality of particles are coated on the external surface of one end away from the battery rod  1  of the lamp cap  2 , the battery cover  4  or the end cover, so that the shape of the lamp cap  2 , the battery cover  4  or the end cover is similar to the shapes of the tobacco leaf and the tobacco shred. Besides, when a lamp body is mounted inside the electronic cigarette, during the simulation of smoking, the light emitted from the lamp body mounted inside the electronic cigarette shines out from the lamp cap  2 , the battery cover  4  or the end cover. Therefore, the lamp body not only has the function of instructing the smoking process, but also makes the lamp cap  2 , the battery cover  4  or the end cover together with the particles  3  coated on the lamp cap  2 , the battery cover  4  or the end cover forming the glowing effect of burning tobacco leaf which is close to the real smoking process, so that the smoking effect is better.
