CROSS REFERENCE TO RELATED APPLICATION 
     This application is the national phase of International Application No. PCT/CN2014/072316, titled “BATTERY ROD ASSEMBLY AND ELECTRONIC CIGARETTE”, filed on Feb. 20, 2014, which claims the priority to Chinese Patent Application No. 201420063805.6, entitled “BATTERY ROD ASSEMBLY AND ELECTRONIC CIGARETTE”, filed with the State Intellectual Property Office of People&#39;s Republic of China on Feb. 12, 2014, the entire disclosure of which is incorporated herein by reference. 
     TECHNICAL FIELD 
     The present application relates to the technical field of electronic cigarettes, and particularly to a battery rod assembly and an electronic cigarette. 
     BACKGROUND 
     A conventional electronic cigarette includes a battery rod assembly and an atomizing assembly, and the atomizing assembly is connected with the battery rod assembly at one end and connected with a suction nozzle at the other end. The atomizing assembly is provided with an aerosol passage in communication with the suction nozzle. The battery rod assembly is provided with a battery cartridge, a battery arranged inside the battery cartridge, and an airflow sensor for controlling the battery to supply power to the atomizing assembly. An airflow passage, which is in communication with the aerosol passage and is connected with the outer surface of the battery rod assembly, is formed between the battery cartridge and the battery. Once a suction performed by a user is sensed by the airflow sensor in the battery rod assembly, an electric heating wire assembly of the atomizing assembly is controlled to atomize the cigarette liquid in the atomizing assembly. 
     From the foregoing, there is no separate aerosol passage in the battery rod assembly. The aerosol generated from the cigarette liquid atomized by the electric heating wire assembly may easily flow into the airflow passage, electronic components inside the battery rod assembly may be immersed by the aerosol, and accordingly, the electronic components are damaged and the service life of the battery rod assembly is affected. In addition, since the suction nozzle of the conventional electronic cigarette is connected to the atomizing assembly, the cigarette liquid in the atomizing assembly is apt to be inhaled in. 
     SUMMARY 
     In view of this, the present application provides a battery rod assembly and an electronic cigarette, which have a long service life. 
     A battery rod assembly includes a battery rod assembly body. 
     The battery rod assembly body includes a suction end, a battery for supplying power to an atomizing assembly of an electronic cigarette, and an aerosol passage communicating with the suction end. 
     The battery and the aerosol passage are arranged inside the battery rod assembly body and are separated from each other.

     a tact switch for controlling the battery to supply power to the atomizing assembly, where the tact switch is electrically connected to the button and the battery. 
     In the battery rod assembly, the battery rod assembly body further includes: 
     a battery cartridge sleeved on the battery; 
     a suction nozzle serving as the suction end, which is detachably connected with the battery cartridge; 
     a battery holder arranged inside the battery cartridge and for retaining the battery; and 
     a battery electrode electrically connected to the battery and the atomizing assembly. 
     An electronic cigarette includes an electronic cigarette body. 
     The electronic cigarette body includes a suction end, a liquid container for containing a cigarette liquid, an atomizing assembly for atomizing the cigarette liquid, and any of the above described battery rod assemblies. 
     The liquid container is arranged at an end of the electronic cigarette body far away from the suction end. 
     In the electronic cigarette, the atomizing assembly is located between the battery rod assembly and the liquid container. The suction end is located at the outside of one end of the battery rod assembly, or is located in a central portion of the battery rod assembly, or is located on the battery rod assembly at a position far away from the atomizing assembly. 
     In the electronic cigarette, the liquid container is detachably connected with the atomizing assembly.

     The air inlet is arranged on an outer wall of the atomizing assembly, or the air inlet is arranged at an abutment face of the atomizing assembly and the liquid container. 
     In the electronic cigarette, the liquid container is a transparent container. 
     In the electronic cigarette, the liquid container is a glass bottle. 
     The present application provides the battery rod assembly and the electronic cigarette. The battery rod assembly includes the battery rod assembly body. The battery rod assembly body includes the suction end, the battery for supplying power to the atomizing assembly of the electronic cigarette, and the aerosol passage communicating with the suction end. The battery and the aerosol passage are separated from each other inside the battery rod assembly body. Since the battery rod assembly body includes a separated and sealed aerosol passage, components inside the battery rod assembly may not be immersed by aerosol generated from cigarette liquid atomized by the atomizing assembly when the battery rod assembly and the atomizing assembly are coupled to form the electronic cigarette, thereby ensuring a long service life of the battery rod assembly. In addition, since the atomizing assembly is arranged at the end of the electronic cigarette far away from the suction end, the user is avoided from inhaling the cigarette liquid with the electronic cigarette including the battery rod assembly.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The present application discloses a battery rod assembly, the structure of which is shown in  FIG. 1 . 
     As shown in  FIG. 1 , the battery rod assembly includes a battery rod assembly body. The battery rod assembly body is provided with a suction end  100 , a battery  101  for supplying power to an atomizing assembly of an electronic cigarette, and an aerosol passage  102  in communication with the suction end  100  and separated from the battery  101 . 
     The aerosol passage  102  provided in the battery rod assembly body is for the flow of atomized cigarette liquid, and a user may inhale, via the suction end  100 , aerosol flowing through the aerosol passage  102 . 
     Further, as shown in  FIG. 1 , the aerosol passage  102  arranged inside the battery rod assembly body may communicate the suction end  100  with an air inlet for conveying air into the electronic cigarette. 
     Preferably, the aerosol passage  102  is sealed inside the battery rod assembly body, i.e., the aerosol passage  102  is separated from other electronic components inside the battery rod assembly body. 
     With the battery rod assembly according to the embodiment, the atomized cigarette liquid flowing through the aerosol passage  102  may not corrode other electronic components in the battery rod assembly since the aerosol passage  102  is sealed inside the battery rod assembly body, and accordingly, the battery rod assembly has improved performance and a long service life. 
     The specific structure of the battery rod assembly is further described in detail below with reference to  FIG. 1 . 
     The battery rod assembly specifically includes a battery cartridge  103 , a battery  101 , a battery holder  105  and a battery electrode  106 . 
     The suction end  100  shown in  FIG. 1  may be formed with an extension of an end portion of the battery cartridge  103 , and the suction end  100  and the battery cartridge  103  are formed integrally. Or, a suction nozzle serving as the suction end  100  is detachably connected to the battery cartridge  103 . Specific configuration is not limited in the embodiment. 
     With the detachable suction nozzle in the embodiment, the user may replace or clean the suction nozzle at any time. Therefore, the cigarette liquid in the suction nozzle is avoided from being inhaled by the user, and the cigarette liquid in the battery rod assembly is easily cleared out. 
     The battery  101  is accommodated inside the battery cartridge  103 . 
     The battery holder  105  for retaining the battery  101  is arranged inside the battery cartridge  103 . 
     The battery electrode  106  is arranged at one end of the battery holder  105 , and is electrically connected to the battery  101  and an atomizing assembly, where the atomizing assembly is arranged inside the electronic cigarette and is for atomizing the cigarette liquid. 
     A connection structure  107  for detachably connecting the battery rod assembly with the atomizing assembly is arranged in the battery rod assembly body. The connection structure  107  is located in the battery rod assembly body at a position far away from the suction end  100 . 
     The battery rod assembly and the atomizing assembly are detachably connected via the connection structure  107 . Specifically, the connection structure  107  may be a thread structure or a rotatable snap structure. The specific structure of the connection structure is not limited in the embodiment as long as a detachable connection of the battery rod assembly and the atomizing assembly may be achieved. 
     Applying the connection structure  107  is advantageous in that, it is convenient for the user to detach the atomizing assembly from the battery rod assembly at any time, and it is convenient for the user to replace the atomizing assembly or charge the battery rod assembly at any time. 
     Further, there are two configurations for the battery rod assembly in the application to control the atomizing assembly to atomize the cigarette liquid. 
     One configuration may be illustrated with reference to  FIG. 1 . In the battery cartridge  103 , an airflow sensor  108  for generating a pulse signal is arranged at a position near the suction end  100 . 
     When the airflow sensor  108  senses that the pressure in the aerosol passage  102  decreases, i.e., when the user sucks the electronic cigarette, the airflow sensor  108  generates the pulse signal. 
     In the embodiment, since the airflow sensor  108  is arranged near the suction end  100 , the air flow sensor  108  has a high sensitivity in sensing suctions of the user. Therefore, the user may use the electronic cigarette more effectively. 
     A microcontroller for generating a control signal based on the pulse signal is provided and connected to the airflow sensor  108  and the battery  101 . The microcontroller is connected to an electric heating wire assembly of the atomizing assembly, and the electric heating wire assembly atomizes the cigarette liquid based on the control signal. 
     With this configuration, tobacco cigarette smoking may be imitated, and the user may inhale the atomized cigarette liquid via the suction end  100 . 
     Another configuration may be illustrated with reference to  FIG. 2 . 
     A button  201  for receiving an operation instruction from the user is arranged on the battery cartridge  103 . 
     A tact switch  202  for generating a control signal based on the operation instruction is provided and is connected with the button  201 . 
     The tact switch  202  is further for controlling the battery  101  to supply power to the atomizing assembly. The tact switch  202  is electrically connected to the button  201  and the battery  101 . 
     With such a configuration, the user does not need to suck the suction end  100  to make the battery  101  to supply power to the atomizing assembly. Once the button  201  is pressed, the battery  101  may supply power to the atomizing assembly, the atomizing assembly atomizes the cigarette liquid, and accordingly, the user may inhale the aerosol. 
     The specific structure of the battery rod assembly provided in the present application is described in detail with the embodiments shown in  FIGS. 1 to 2 . The specific structure of an electronic cigarette including the battery rod assembly in the above embodiments is described in detail hereinafter in conjunction with an embodiment shown in  FIG. 3 . 
     An electronic cigarette shown in  FIG. 3  includes an electronic cigarette body. 
     The electronic cigarette body includes a suction end  100 , a liquid container  301  and an atomizing assembly  302 . 
     The user may smoke through the suction end  100 . 
     The liquid container  301  is configured to contain a cigarette liquid, i.e., an atomizable cigarette liquid is stored in the liquid container  301 . 
     The atomizing assembly  302  is configured to atomize the cigarette liquid, i.e., the cigarette liquid within the liquid container  301  may be atomized by the atomizing assembly  302 . 
     The electronic cigarette body further includes a battery rod assembly  303  for supplying power to the atomizing assembly  302 . 
     The specific structure of the battery rod assembly  303  may be known with reference to the embodiments shown in  FIGS. 1 to 2 , which is not repeated here. 
     As shown in  FIG. 3 , the liquid container  301  is arranged at an end of the electronic cigarette body far away from the suction end  100 . In this configuration, an aerosol passage inside the electronic cigarette body is not in communication with the liquid container  301  since the liquid container  301  is far away from the suction end  100 , unatomized cigarette liquid in the liquid container  301  may not leak into the aerosol passage, and accordingly, the user may not inhale the unatomized cigarette liquid, thereby effectively avoiding the leakage of the cigarette liquid. In addition, since the aerosol passage is not in communication with the liquid container  301 , the aerosol is avoided from condensing in the aerosol passage, and accordingly, the aerosol passage is effectively avoided from being blocked by condensed cigarette liquid. 
     The specific structure of the electronic cigarette according to the embodiment is further described in detail in conjunction with  FIG. 3 . The atomizing assembly  302  is located between the battery rod assembly  303  and the liquid container  301 . The suction end  100  is located at the outside of one end of the battery rod assembly  303 , or the suction end  100  is located in a central portion of the battery rod assembly  303 , or the suction end  100  is located on the battery rod assembly  303  at a position far away from the atomizing assembly  302 . 
     Specifically, for the suction end  100  located at the outside of one end of the battery rod assembly  303 , the suction end  100  and the battery rod assembly  303  may be coaxially arranged. With this configuration, the electronic cigarette has an intuitive imitation of the appearance of a tobacco cigarette, and the overall aerosol passage is relatively straight, thereby effectively reducing accumulation of the cigarette liquid. 
     Alternatively, the suction end  100  is arranged in the central portion of the battery rod assembly  303 , or the suction end  100  is located on the battery rod assembly  303  at a position far away from the atomizing assembly  302 . 
     In the present application, the specific position of the suction end  100  is not limited. 
     In the embodiment, the atomizing assembly  302  and the battery rod assembly  303  are coaxially arranged, to provide the electronic cigarette with an overall structure similar to a tobacco cigarette, to be accordant with customary use of the user, and to reduce accumulation of the cigarette liquid. 
     Certainly, the specific configuration is not limited in the embodiment. For example, the battery rod assembly  303 , the atomizing assembly  302  and the liquid container  301  which are connected successively may be arranged unevenly, and consequently, the overall appearance of the electronic cigarette may be irregular and the electronic cigarette may be in any irregular shape. 
     Alternatively, the atomizing assembly  302  and the battery rod assembly  303  may not be coaxially arranged. The liquid container  301  and the atomizing assembly  302  may be arranged parallel to each other, the liquid container  301  and the atomizing assembly  302  are respectively connected to the battery rod assembly  303 , and the overall structure of the electronic cigarette is in a T-shape. 
     Therefore, the overall structure of the electronic cigarette is not limited in the embodiment as long as the liquid container  301  is arranged at a position far away from the suction end  100 . 
     In the embodiment, the atomizing assembly  302  is located between the battery rod assembly  303  and the liquid container  301 , and the atomizing assembly  302  is far away from the suction end  100 . In using the electronic cigarette according to the embodiment, the user may not be scalded by the heat generated when the atomizing assembly  302  atomizes the cigarette liquid since the atomizing assembly  302  is far away from the mouth; hence, the security in using the electronic cigarette is effectively improved. In addition, the user generally holds the battery rod assembly  303  when using the electronic cigarette, rather than holds the heating atomizing assembly  302  as in conventional art. Therefore, the temperature of the tobacco cigarette is effectively imitated, and the user may not scald the hand when using the electronic cigarette according to the embodiment, thereby improving the user experience during smoking. 
     Preferably, the liquid container  301  is detachably connected with the atomizing assembly  302  and/or the atomizing assembly  302  is detachably connected with the battery rod assembly  303 . 
     Specifically, the detachable connection between the liquid container  301  and the atomizing assembly  302  and/or the detachable connection between the atomizing assembly  302  and the battery rod assembly  303  may be a thread connection or an engagement connection, etc. The specific way of connection is not limited in the embodiment, as long as the liquid container  301  is detachably connected with the atomizing assembly  302  and/or the atomizing assembly  302  is detachably connected with the battery rod assembly  303 . 
     Applying the above detachable connection is advantageous in that, it is convenient for the user to replace the atomizing assembly  302  at any time, and the user may detach the liquid container  301  at any time to conveniently add the cigarette liquid into the liquid container  301  or to replace the liquid container  301 . The connection between the liquid container  301  and the atomizing assembly  302  and/or the connection between the atomizing assembly  302  and the battery rod assembly  303  may be non-detachable, which is not limited here. 
     The specific structure of the atomizing assembly of the electronic cigarette is described in detail below in conjunction with an embodiment shown in  FIG. 4 . 
     As shown in  FIG. 4 , the atomizing assembly  302  includes: an atomizer holder  401 , a first threaded bushing  402 , an atomizer electrode  403 , an insulating ring  404 , an electric heating wire assembly  405 , a liquid-guiding mechanism  406  and an atomizer cartridge  407 . 
     The first threaded bushing  402  is arranged on the top of the atomizer holder  401  and is detachably connected with the battery rod assembly  303 . 
     In the embodiment, it is illustrated with an example that the atomizing assembly  302  and the battery rod assembly  303  are threadedly connected. The first threaded bushing  402  is arranged on the top of the atomizer holder  401  if the atomizing assembly  302  and the battery rod assembly  303  are to be threadedly connected. If other detachable connection structures are to be used, other connection structures may be arranged on the top of the atomizer holder  401 , for example, an elastic strip is provided for an engagement connection. In the embodiment, the threaded bushing is only taken as an example, while the connection structure is not limited to the threaded bushing. 
     The atomizer electrode  403  is fixed inside the first threaded bushing  402 . 
     The insulating ring  404  is arranged between the first threaded bushing  402  and the atomizer electrode  403 . 
     The electric heating wire assembly  405  is electrically connected to the atomizer electrode  403 , and the cigarette liquid may be atomized by the electric heating wire assembly  405 . 
     The liquid-guiding mechanism  406  is for guiding the cigarette liquid within the liquid container  301  to the electric heating wire assembly  405  to be atomized. The liquid-guiding mechanism  406  may include liquid-guiding cotton, liquid-guiding fiber and so on, which is not limited here. 
     The atomizer cartridge  407  is arranged on the atomizer holder  401 , and the liquid-guiding mechanism  406  is arranged in the atomizer cartridge  407 . 
     Specifically, the atomizer cartridge  407  is inserted into the liquid container  301 , and at least one liquid hole is arranged on the circumferential wall of the atomizer cartridge  407 . The cigarette liquid within the liquid container  301  can be conveyed to the liquid-guiding mechanism  406  smoothly via the at least one liquid hole. 
     The specific structure of the liquid container according to the present application is detailed below in conjunction with an embodiment shown in  FIG. 5 . 
     As shown in  FIG. 5 , a sealed chamber  501  is arranged inside the liquid container  301 . The cigarette liquid is sealedly stored in the sealed chamber  501 . 
     To make the user acquire the amount of the cigarette liquid remained in the liquid container  301 , the liquid container  301  is a transparent container. The user may acquire, at any time, the amount of the cigarette liquid remained in the electronic cigarette with the transparent liquid container  301 , which facilitates the user in replacing the liquid container  301  in time. 
     Preferably, the liquid container  301  is a glass bottle. Since the property of glass is relatively stable, the smell of the cigarette liquid is avoided from being affected due to, for example, chemical reactions. 
     Preferably, an outer circumferential wall of the liquid container  301  made of glass is provided with calibrations. Hence, the user may estimate an available smoking duration with the remained cigarette liquid, which is convenient in using. 
     Preferably, a protective cartridge (not shown in the Figure) is sleeved on the liquid container  301 , to protect the liquid container  301  made of glass from being broken due to falling off. 
     Preferably, the protective cartridge is provided with a cigarette liquid observation window for the user to observe the cigarette liquid. 
     For imitating the tobacco cigarette, the length of the electronic cigarette is generally same as that of the tobacco cigarette. For reducing a charging frequency and for ensuring a long service life of the battery rod assembly  303 , the length of the battery rod assembly  303  may be equal to or longer than half of the whole length of the electronic cigarette. When the user uses the electronic cigarette according to the embodiment, he or she may naturally hold the electronic cigarette at an upper-middle portion of the electronic cigarette close to the suction end  100 . The liquid container  301  may not be subjected to a holding force applied by the user since the liquid container  301  in the embodiment is arranged at an end far away from the suction end  100 . Accordingly, the liquid container  301  outputs a relatively stable amount of the cigarette liquid to the atomizing assembly  302 , thereby effectively ensuring a stable supply of aerosol and improving the user experience. Unstable amount of the aerosol, which is due to changing supplies of the cigarette liquid in response to changing forces applied at the end portion of the atomizing assembly by the user in the prior art, is avoided. 
     For sealing the liquid container  301  effectively and further avoiding the leakage of the cigarette liquid effectively, two arrangements are provided in the embodiment. 
     A first configuration is illustrated with reference to  FIG. 4 . For efficiently sealing the liquid container  301  connected to the atomizing assembly  302  and avoiding the leakage of the cigarette liquid in the liquid container  301 , a sealing ring  408  for sealing the liquid container  301  is provided at a position where the atomizer holder  401  is connected with the liquid container  301 . 
     The liquid container  301  can be sealed effectively by the sealing ring  408  arranged on the atomizer holder  401 . 
     A second configuration is illustrated with reference to  FIG. 5 . An annular sealing plug  502  having a through hole is provided and sealedly coupled with an opening of the liquid container  301 . 
     A piercable thin film  503  for sealing the liquid container  301  is arranged in the through hole of the annular sealing plug  502 . 
     When inserting the atomizer cartridge  407  into the sealed chamber  501  of the liquid container  301 , the atomizer cartridge  407  penetrates the piercable thin film  503 . With the piercable thin film  503 , the liquid container  301  with the atomizer cartridge  407  inserted therein still have a good sealing, thereby effectively avoiding the leakage of the cigarette liquid. 
     Since the liquid container  301  in the embodiment is provided with the annular sealing plug  502  having the pierable thin film  503 , the liquid container  301  has a good sealing, which effectively avoids the leakage of the cigarette liquid and ensures a long service life of the electronic cigarette. 
     An aerosol passage  102 , which is sealed and is configured to communicate the suction end  100  with an air inlet, is arranged inside the electronic cigarette of the present application. 
     Preferably, the aerosol passage  102  is sealed inside the battery rod assembly  303 , i.e., the aerosol passage  102  is separated from other electronic components inside the battery rod assembly  303 , which ensures the performance of the battery rod assembly and the service life of the electronic cigarette. 
     Specifically, the air inlet communicating with the aerosol passage  102  may be arranged in two ways. It should be known that the following arrangements of the air inlet are merely exemplary and are not for limitations, as long as the air inlet arranged in the electronic cigarette body can be communicated with the suction end  100  via the aerosol passage  102 . 
     In a first arrangement, the air inlet may be arranged at an abutment face of the atomizing assembly  302  and the liquid container  301 . Specifically, a protrusion or a rib may be arranged on the abutment face of the atomizing assembly  302  and the liquid container  301 . Hence, an air inlet for entering of air is formed between the atomizing assembly  302  and the liquid container  301  which are threadedly connected with each other, and the air can flow into the aerosol passage  102  via the air inlet. 
     It should be noted that the way for arranging the air inlet is not limited, as long as an air inlet for entering of the air is formed between the atomizing assembly  302  and the liquid container  301 . 
     The suction end  100  can be communicated with the air inlet via the aerosol passage  102 .  FIG. 6  is a schematic sectional view of an electronic cigarette having an air inlet arranged on the abutment face of the atomizing assembly  302  and the liquid container  301 . 
     As shown in  FIG. 6 , the air inlet arranged on the abutment face of the atomizing assembly  302  and the liquid container  301  is communicated with the suction end  100  via the aerosol passage  102 . 
     Specifically, the direction of the airflow in the electronic cigarette in the embodiment is indicated by arrows shown in  FIG. 6 . The airflow does not pass the liquid container  301 . The aerosol atomized by the atomizing assembly  302  may flow to the suction end  100  without passing the liquid container  301 ; hence, the aerosol is avoided from condensing due to aerosol-absorbtion of the liquid container  301 , and the aerosol passage  102  is further avoided from being blocked. 
     In a second arrangement, the air inlet may be arranged on an outer wall of the atomizing assembly  302 , while the position and the number of the air inlet are not limited. 
     The suction end  100  can be communicated with the air inlet via the aerosol passage  102 .  FIG. 7  is a schematic sectional view of an electronic cigarette having an air inlet arranged on the outer wall of the atomizing assembly  302 . 
     As shown in  FIG. 7 , the air inlet, which is arranged on the outer wall of the atomizing assembly  302 , is communicated with the suction end  100  via the aerosol passage  102 . 
     Specifically, the direction of the airflow inside the electronic cigarette in the embodiment is indicated by arrows shown in  FIG. 7 . The airflow does not pass the liquid container  301 . The aerosol atomized by the atomizing assembly  302  may flow to the suction end  100  without passing the liquid container  301 ; hence, the aerosol is avoided from condensing due to aerosol-absorbtion of the liquid container  301 , and the aerosol passage  102  is further avoided from being blocked. A conventional situation that, the aerosol condenses when passing a liquid-containing region and the aerosol passage is blocked, is avoided. 
     An electronic cigarette according to an embodiment of the present application may have a light effect imitating a tobacco smoking effect. A specific structure is illustrated with reference to  FIG. 8 . The electronic cigarette shown in  FIG. 8  includes a suction end  100  and a battery rod assembly  303 , the specific structures of which can be known with reference to previous embodiments and are not repeated here. 
     In the embodiment, a liquid container  301  is integrated with an atomizing assembly  302 , and the liquid container  301  is arranged at an end of the electronic cigarette body far away from the suction end  100 . 
     Preferably, an aerosol passage  102  is arranged inside the liquid container  301 , and an air inlet, which is in communication with the aerosol passage  102 , is arranged at the bottom of the liquid container  301 . The aerosol passage  102  extends to the suction end  100  and is in communication with the suction end  100 . 
     The direction of airflow in the electronic cigarette is indicated by arrows shown in  FIG. 8 . As shown in  FIG. 8 , the aerosol passage  102  in the embodiment is longer than those in the previous embodiments. The temperature of the aerosol atomized by an electric heating wire assembly  8  may decrease due to the long aerosol passage  102 , thereby ensuring the smoking experience of the user. 
     Preferably, a lighting module  801  may be arranged at the bottom of the electronic cigarette body. When the user sucks at the suction end  100 , the lighting module  801  may emit light for imitating the burning of tobacco. Apparently, different light patterns can be set according to requirements of users to achieve different effects. 
     An end cap  802  for encasing the lighting module  801  is arranged at the bottom of the electronic cigarette body, and the end cap  802  may be transparent or opaque. 
     To convey the cigarette liquid within the liquid container to the liquid-guiding mechanism more easily, an electronic cigarette having another structure is described in detail in conjunction with an embodiment shown in  FIG. 9 . 
     As shown in  FIG. 9 , the electronic cigarette includes a suction end  100  and a battery rod assembly  303 , while the specific structures of which can be known with reference to the above embodiments and are not repeated here. 
     In the embodiment, a liquid container  301  for containing a cigarette liquid is arranged on an outer circumferential wall of an atomizing assembly  302 , the cigarette liquid within the liquid container  301  is conveyed to a liquid-guiding mechanism  406  inside a atomizer cartridge  407  via a liquid hole arranged on the atomizer cartridge  407 , and then the cigarette liquid is atomized by an electric heating wire assembly  405 . The specific structure inside the atomizing assembly  302  can be known with reference to the above embodiments and is not limited in the embodiment. 
     In the embodiment, the flow direction of the cigarette liquid within the liquid container  301  is perpendicular to or angled to that of the cigarette liquid located in the atomizer cartridge  407  and conveyed to the electric heating wire assembly  405  to be atomized, to avoid the cigarette liquid from being overly conveyed to the atomizer due to vibration and so on. Thus, the cigarette liquid within the liquid container  301  can be conveyed to the liquid-guiding mechanism  406  inside the atomizer cartridge  407  stably, which ensures a stable amount of the aerosol. In addition, with this structure, the liquid container  301  made of glass may be avoided from being broken once the electronic cigarette falls off and the end portion of the electronic cigarette hits the ground. 
     In the embodiment, the liquid container  301  is threadedly connected to the atomizing assembly  302 . Other ways such as an engagement connection may be alternatively used. The specific connection way is not limited in the embodiment. 
     It should be noted that, in the embodiment, the number and specific position of the liquid container  301  arranged on the side wall of the atomizing assembly  302  are not limited. 
     As shown in  FIG. 9 , if one liquid container  301  is arranged on the side wall of the atomizing assembly  302 , the electronic cigarette body presents in an L-shape. 
     Or, as shown in  FIG. 10 , if two liquid containers  301  are arranged on the side wall of the atomizing assembly  302  and the two liquid containers  301  are opposite to each other, the electronic cigarette body presents in a T-shape.
