Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to electronic cigarettes, and particularly to a battery assembly and an electronic cigarette using same. 
       DESCRIPTION OF RELATED ART 
       [0002]    Electronic cigarettes are similar to conventional cigarettes in appearance and taste, but less harmful to human&#39;s health, such that electronic cigarettes are widely used for helping people to quit smoke. A typical electronic cigarette includes an atomizing device and a battery assembly. When users smoke at an end of the atomizing device, the battery assembly powers the atomizing device, then the users can have the smoking feelings. 
         [0003]    In current battery assemblies, electrode rings used to be electrically connected to the atomizing device are usually fixed at an end of the battery assemblies, such that in some situations, the electrode rings may be not well connected to the atomizing devices due to position differences in different battery assemblies. 
         [0004]    What is needed, therefore, is a battery assembly with a resilient electrode ring and an electronic cigarette using same, which can overcome the above shortcomings.

     DETAILED DESCRIPTION 
       [0014]    Embodiments of the present battery assembly and electronic cigarette will now be described in detail below and with references to the drawings. 
         [0015]    Referring to  FIG. 1 , an electronic cigarette  100  includes an atomizer  10  and a battery assembly  20 . One end of the atomizer  10  has a suction nozzle  11 , and the other end of the atomizer  10  is connected to the battery assembly  20 . 
         [0016]    Referring to  FIGS. 2 and 3 , the battery assembly  20  mainly includes a battery sleeve  21 , a battery  22  received in the battery sleeve  21 , a screw sleeve  23  located at an end of the battery  22 , an electrode ring  24 , an insulated ring  25 , an elastic member  26 , a fixing base  27  and a ring-shaped silicone rubber spacer  28 . 
         [0017]    The battery  22  is a storage battery, and can be charged in need. The battery sleeve  21  and the screw sleeve  23  are all made of metallic materials, and the screw sleeve  23  is fixed in the battery sleeve  21 . In the present embodiment, the screw sleeve  23  has inner screws  232 , and is connected to the atomizer  10  by the inner screws  232 . 
         [0018]    The insulated ring  25  is fixed in the screw sleeve  23 , and is made of an insulated material, such as a plastic material. The insulated ring  25  has a through hole  256  defined through the insulated ring  25 . In the present embodiment, the elastic member  26  is an elastic member. 
         [0019]    The electrode ring  24 , elastic member  26  and fixing base  27  are received in the through hole  256 . The electrode ring  24  extends through the through hole  256  towards the atomizer  10  and is fixed at the fixing base  27  via the elastic member  26 . The through hole  256  has a certain depth, and the electrode ring  24  is spaced a certain distance from the fixing base  27 , thereby the electrode ring  24  can be moved upwards and downwards due to the elastic member  26 . In the present embodiment, the insulated ring  25  has a ring-shaped protrusion  252  at an outer wall thereof, and the screw sleeve  23  has a ring-shaped recess  232  at an inner wall thereof, thereby fixing the insulated ring  25  in the screw sleeve  23 ; in addition , the fixing base  27  has a ring-shaped recess  272  at an outer wall thereof, and the insulated ring  25  has a ring-shaped protrusion  254  at an inner wall thereof, thereby fixing the fixing base  27  in the insulated ring  25 . 
         [0020]    The fixing base  27  includes a bottom plate  272 , a circular side wall  274  extending upwards from the bottom plate  272 , and an annular projection  276  projected upwards and downwards from a central position of the bottom plate  272 . The annular projection  276  has an air through hole  278  defined in a center thereof. The bottom plate  272  and the circular side wall  274  cooperatively form a container configured for receiving oil leaked from the atomizing device  10 , thereby avoiding pollution to the battery  22 . 
         [0021]    The fixing base  27  is made of a metallic material. The electrode ring  24 , the elastic member  26  and the fixing base  27  are electrically contacted one by one. The fixing base  27  is electrically connected to one pole, preferably the negative pole of the battery  22  via a wire  291 , and the wire  291  can be welded to a bottom of the fixing base  27 . Another pole, preferably the positive pole of the battery  22  can be electrically connected to the screw sleeve  23  via a wire  292 . 
         [0022]    The silicone rubber spacer  28  is positioned at a distal end of the screw sleeve  23 , and is located between the screw sleeve  23  and the battery  22 . The silicone rubber spacer  28  is configured for avoiding the screw sleeve  23  and other elements pressing the battery  22 . 
         [0023]    The battery assembly  20  further has a light emitting element  32  and a cover  34  with at least one air through hole  36 . Light can be transmitted through the cover  34 , such that when a user sucks the nozzle  11  of the atomizing device  10 , air flow makes the battery assembly  20  power the atomizing device  10 , and the light emitting element  32  emit light at the same time. Light then can transmit through the cover  34 , such that the electronic cigarette  100  can have a conventional cigarette burning feeling. 
         [0024]    Concluded from the above description, the electrode ring  24  is fixed in the through hole  256  via the elastic member  26 . Due to the elasticity of the elastic member  26  and a depth of the through hole  256 , a connection depth between the electrode ring  24  and the atomizing device  10  can be adjusted, thereby the connection of battery assembly  20  and the atomizing device  10  is easy, and the battery assembly  20  can be applicable for various atomizing devices  10 . The battery assembly  20  therefore may be assembled automatically by machine. The fixing base  27  can avoid pollution of the oil from the atomizing device  10  to the battery  22 .

         [0028]    Referring to  FIG. 8 , a battery assembly  80  of an electronic cigarette of a fourth embodiment is provided. The difference between the battery assembly  80  of the fourth embodiment and the battery assembly  20  of the first embodiment is that an elastic element  86  of the battery assembly  80  is a silicon rubber ring. The silicon rubber ring is preferably electrically conductive. A battery sleeve  81 , a battery  82 , a screw sleeve  83 , an electrode ring  84 , an insulated ring  85 , a fixing base  87  and a silicone rubber spacer  88  of the battery assembly  80  are the same as the elements in the battery assembly  20  of the first embodiment. 
         [0029]    In other embodiments, the elastic element may be a fibre ring, hydraulic device or other rubber rings. The elastic element can be electrically conductive or insulated, and wires can be applied to electrode ring when the elastic element is insulated.
