     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0022]    Specific implementations of the present invention is explained in detail in accordance with accompanying drawings so that the technical feature, objective and effect of the present invention can be understood more clearly. 
         [0023]    In order to solve the drawback of low production efficiency caused by the difficulty in assembly of the existing electronic cigarette atomizer shown in  FIG. 1 , an electronic cigarette atomizer shown in  FIG. 2  is provided in the present invention. The electronic cigarette atomizer of the present invention comprises a male screw bushing  210  and a top electrode  220 , and the male screw bushing  210  and a battery rod component of an electronic cigarette are assembled together via a threaded connection. When the male screw bushing  210  is connected to the battery rod component, the male screw bushing  210  and the top electrode  220  are connected to a positive electrode and a negative electrode of the battery respectively. To prevent short circuit incidents, the top electrode  220  is insert into a dead ring  230  firstly, and the dead ring  230  engages with the interior of the male screw bushing  210  subsequently, thereby making the male screw bushing  210  and the top electrode  220  be electrically isolated from each other. 
         [0024]    The electronic cigarette atomizer further comprises a heating wire component  240 . One lead pin of the heating wire component  240  inserts into a gap formed between the top electrode  220  and the dead ring  230 , the other lead pin of the heating wire component  240  inserts into a gap formed between the male screw bushing  210  and the dead ring  230 , so that the two lead pins are electrically connected to the male screw bushing  210  and the top electrode  220  respectively. When electric current passes the heating wire component  240 , it is transformed into heat. A main heating body of the heating wire component  240  is positioned adjacent to the top electrode  220 , the lead pin of the heating wire component  240  is very short, so that the whole heating wire component  240 , the male screw bushing  210 , the top electrode  220  and the dead ring  230  cooperatively form an electrode part. 
         [0025]    The electronic cigarette atomizer further comprises a breather pipe  250 , which is hollow and cylinder-shaped. One end of the breather pipe  250  defines at least one U-shaped opening(s) therein. For example, in the embodiment of the present invention, two U-shaped openings of the same size are defined in two opposite positions of one end of the breather pipe  250  respectively, and the two U-shaped openings is aligned with and inserted into the heating wire component  240 , such that the heating body of the heating wire component  240  is positioned inside the hollow interior of the breather pipe  250 . Besides, because the main heating body of the heating wire component  240  matches with the structure of the U-shaped opening(s), a structure of the electronic cigarette atomizer becomes more compact, and the heating body is prevented from being dropped from the U-shaped opening(s) of the breather pipe  250 . 
         [0026]    An outer sleeve  280  is mounted on an outer surface of the electronic cigarette atomizer, and the outer sleeve  280  is hollow and cylinder-shaped. The male screw bushing  210  screws into an opening of one end of the outer sleeve  280 , and a reception space is formed between the outer sleeve  280  and the breather pipe  250 . A piece of oil-absorbing cotton  260  is received inside the reception space. Liquid tobacco juice is stored in the oil-absorbing cotton  260 . A suction nozzle cover  270  is attached to the other end of the outer sleeve  280 , a center of the suction nozzle cover  270  defines through-hole(s) therein, and the through-hole(s) communicate(s) with the hollow part of the breather pipe  250 . 
         [0027]    In use of the electronic cigarette atomizer, electric current is transformed into heat by the heating wire component  240 , and the tobacco juice stored in the oil-absorbing cotton  260  is atomized by heat generated by the heating wire component  240  in the breather pipe  250 . The atomized tobacco juice flows along the breather pipe  250  and outflows from the through-hole(s) of the suction nozzle cover  270 . 
         [0028]    In manufacturing and assembly of an electronic cigarette atomizer, the male screw bushing  210 , the top electrode  220 , the dead ring  230  and the heating wire component  240  are manufactured and assembled as an electrode part. The main heating body of the heating wire component  240  is configured to pass a central axis of the top electrode  220 , and an extending orientation of the main heating body is perpendicular to the central axis of the top electrode  220 . As shown in  FIG. 3 , in assembly of the electronic cigarette atomizer, the heating wire component  240  of the electrode part is aligned with and inserted into the U-shaped opening (s) of the breather pipe  250  is/are aligned with the heating wire component  240 , and an end of the heating wire component that is adjacent to the U-shaped opening(s) is further inserted into the top electrode  220 , and thus the breather pipe  250  is positioned fixedly relative to the electrode component. After that, the breather pipe  250  is aligned with and inserted into the through-hole of the center of the oil-absorbing cotton  260 , and the outer sleeve  280  sleeves outside the oil-absorbing cotton  260 , such that the male screw bushing  210  is in tight contact with the opening of one end of the outer sleeve  280 . Finally, the suction nozzle cover  270  engages with the opening of the other end of the outer sleeve  280 , and the whole assembly process of the electronic cigarette atomizer is finished. Compared with original assembly methods, contacting and assembly between the interface of the heating wire component  240  and the electrode is omitted, and the production efficiency is improved. It should be understand that the assembly sequence is not limited and can be diversified. For example, the assembly sequences of the oil-absorbing cotton  260  and the assembly sequence of the outer sleeve  280  can replace each other, that is, the male screw bushing  210  can be firstly screwed into an opening of one end of the outer sleeve  280  tightly; the oil-absorbing cotton  260  can be second inserted into the reception space formed between the outer sleeve  280  and the breather pipe  250 ; and the suction nozzle cover  270  can be finally mounted onto the other end of the outer sleeve  280 . 
         [0029]    How the male screw bushing  210 , the top electrode  220 , the dead ring  230  and the heating wire component  240  are manufactured and assembled as one electrode part is illustrated in detail in  FIG. 4  in the following. The male screw bushing  210  is a conductive component, the exterior of the male screw bushing  210  forms thread shapes thereon, and the interior of the male screw bushing  210  is a hollow structure. The interior of the male screw bushing  210  receives a dead ring  230  with an center hole, the outer wall of the dead ring  230  is in tight contact with the inner wall of the male screw bushing  210  each other, and a top electrode  220  is inserted into the center hole of the dead ring  230 . One end of the top electrode  220  positioned adjacent to the male screw does not exceed the end of the male screw bushing  210 , and the other end of the top electrode  220  protrudes slightly relative to the dead ring  230  to communicate with the breather pipe  250  easily. In order to achieve a more compact assembly and prevent the internal components of the electronic cigarette atomizer from moving relative to each other, the dead ring  230  is made of rubber with elastic characteristic or silica gel, and the dead ring  230  will be compressed slightly when it is completely assembled. The dead ring  230  presses the top electrode  220  and the male screw bushing  210  simultaneously due to recovery of elasticity ability thereof, which makes the dead ring  230 , the top electrode  220  and the male screw bushing  210  be positioned fixedly relative to each other. That is, an outer diameter of the dead ring  230  is designed to be a little longer than an inner diameter of the male screw bushing  210 , and an inner diameter of the dead ring  230  is designed to be a little shorter than an outer diameter of the top electrode  220 . The heating wire component  240  comprises two lead pins: a first lead pin  241  and a second lead pin  242 . The first lead pin  241  inserts between the male screw bushing  210  and the dead ring  230 , and the second lead pin  242  inserts between the top electrode  220  and the dead ring  230 . Due to the elastic recovery ability of the dead ring  230 , the first lead pin  241  and the second lead pin  242  are in tight contact with the male screw bushing  210  and the top electrode  220  respectively to ensure an optimized electrical connection effect. The male screw bushing  210 , the top electrode  220 , the dead ring  230  and the heating wire component  240  are integrated into an electrode part with the function of pinch effect of the dead ring  230 , which prevents the heating wire component  240  from generating point-to-point contacts with the male screw bushing  210  and the top electrode  220  in assembly, so that it is more convenient for the assembly of an electronic cigarette atomizer in the present invention. 
         [0030]    It is preferred that some modifications can also be made for the heating wire component  240  shown in  FIG. 4 , which are embodied as follows: the heating body  243  is twined with a heating wire (not labeled), and two ends of the helispherical heating wire extend to connect to two lead pins respectively (i.e., the first lead pin  241  and the second lead pin  242 ), the heating wire, the first lead pin  241  and the second lead pin  242  are formed integrally. Because structures of the first lead pin  241  and the second lead pin  242  are shaped as straight needles, the dead ring  230  may often be impaled by the first lead pin  241  and the second lead pin  242  during the insertion actions of the first lead pin  241  and the second lead pin  242 . The heating wire component  240  is further modified to form a shape shown in  FIG. 5  in the present invention. The first lead pin  241  and the second lead pin  242  are modified to be bent and form bent parts. In this way, the possibility of an impaled dead ring  230  caused by insecting the first lead pin  241  and the second lead pin  242  into the corresponding gaps can be reduced, and the circumstance of an impaled dead ring  230  is unlikely to happen. Moreover, it is easy to insert every needle-shaped lead pin into the corresponding gap. 
         [0031]    The embodiments of the present invention are described in accordance with accompanying figure, however, the present invention shall not be limited to the above-mentioned embodiments which are only considered as some demonstrations instead of limitation to the present invention. Lots of modalities can be made by the one skilled in the art with the help of the inspiration from the present invention without breaking away from the principle and scope of protection of the claims, wherein these modalities are within the scope protected by the present invention.
