     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     As seen in  FIGS.  1 - 8   , the electronic vaporizer has an upper portion and a lower portion. The upper portion retains a right cartridge  12  and a left cartridge  13 . The upper portion has a mouthpiece with a right mouthpiece opening  18  and a left mouthpiece opening  19 . The mouthpiece has a wide mouthpiece portion  15  below a narrow mouthpiece portion  16  with a mouthpiece shoulder  16 . The upper portion of the housing and the lower portion of the housing meet at a housing interface  14 . The lower portion of the housing has a USB connection  39 . The lower portion of the housing also has indicator lights  110 . The indicator lights include a first LED  111 , a second LED  112 , a third LED  113 , and a fourth LED  114 . The general exterior of the device shows that the upper section  20  and the lower section  30  meet at a flush interface. 
     As seen in  FIGS.  9 - 10   , the upper section  20  has an upper housing  21 , and the lower section  30  has a lower housing  31 . The lower section  30  has a lower frame  38  mounted to the inside of the lower housing  31 . The lower frame retains the battery  37 . The battery  37  powers a right airflow sensor  34  and a left airflow sensor  33 . The button switch  36  and USB socket  39  are also mounted to the lower section  30 . USB stands for uniform serial bus which allows charging and data transfer. The USB socket  39  and control button  35  can be mounted to a printed circuit board  32 . The button switch  36  is activated via the control button  35  which is slidingly mounted to a control button opening in the lower frame  38 . 
     The interface frame  40  is mounted in an upper portion of the lower section  30 . The interface frame  40  retains a first left spring loaded electrical contact  46  and a second left spring loaded electrical contact  47  on a left side of the interface frame  40 . The interface frame  40  also retains a first right spring loaded electrical contact  48  and a second right spring loaded electrical contact  49  on the right side of the interface frame  40 . The four spring loaded electrical contacts electrically connect to the cartridge contacts. The first right cartridge contact  65  makes electrical connection with the first right spring loaded electrical contact  48 , and the second right cartridge contact  66  makes electrical connection with the second right spring loaded electrical contact  49 . Similarly, the first left cartridge contact  67  makes electrical contact with the second left spring loaded electrical contact  47 , and the first left spring loaded electrical contact  46  makes electrical contact with the second left cartridge contact  68 . The right cartridge metal frame  61  retains the first right cartridge contact  65  and the second right cartridge contact  66 . Similarly, the left cartridge metal frame  62  retains the first left cartridge contact  67  and the second left cartridge contact  68 . 
     The electrical contacts power a right heater  28  and a left heater  29 . The right heater  28  is in fluid flow with a right chimney  26 , and the left heater  29  is in fluid flow with a left chimney  27 . The right chimney  26  has exhaust that passes through a right chimney port  55 , and the left chimney  27  has a fluid flow that passes through the left chimney port  56 . The right cartridge  12  has a right tank  22  fillable with right tank oil  23  through a right fill port  52 . A right plug  51  can close the right fill port  52 . The right fill port  52  is located below the right mouthpiece opening. Similarly, the left cartridge  13  has a left tank  24  that receives the left tank oil  25  through a left fill port  59 . The left fill port  59  can be closed using a left plug  54 . The upper section  20  having an upper housing  21  retains the cartridges. 
     The cartridges have a right cartridge metal frame  61  and a left cartridge metal frame  62 . The right cartridge metal frame  61  has a right metal frame airflow opening  63 , and the left cartridge metal frame  62  has a left metal frame airflow opening  64 . The right cartridge metal frame  61  magnetically latches to the first right latch magnet  42 , and the second right latch magnet  43 . The left cartridge metal frame  62  magnetically latches to the first left latch magnet  44  and the second left latch magnet  45 . The latch magnets are mounted to the left and right of the intake passages. 
     The right heater  28  receives the flow of oil from the right tank oil  23  and vaporizes it so that it passes through the right chimney port  55 . Similarly, the left heater  29  receives a flow of left tank oil  25  which vaporizes so that it passes through the left chimney  27 . 
     As seen in  FIG.  10   , the upper section  20  detaches from the lower section  30  exposing the cartridges. The pair of cartridges is arranged with a right cartridge and a left cartridge. The cartridges are flat and elongated such that the upper section  20  and the lower section  30  are flat and elongated. The cartridges have an air intake while limiting leaking of oil. The cartridges fit into the socket  70 . The right cartridge fits into the right socket  71 , and the left cartridge fits into the left socket  72 . As the exhaust exits from the right chimney port  55 , it passes along a lower surface of a right insulator  57 , and as exhaust exits from the left chimney port  56 , it passes along a lower surface of a left insulator  58 . The right gasket  50  has a right chimney port  55 , and the left gasket  53  has a left chimney port  56 . 
     The right socket  71  has a right socket latch spring  75  that engages a right socket latch slot  73 , thereby retaining the right cartridge. Similarly, the left socket  72  has a left socket latch spring  76  that engages a left socket latch slot  74  thereby retaining the left cartridge. The metal frame assembly  60  includes a right cartridge metal frame  61  and a left cartridge metal frame  62 . The right cartridge metal frame  61  can be crimped to a lower portion of the right cartridge, and the left cartridge metal frame  62  can be crimped to a lower portion of the left cartridge. Accordingly, the upper housing  21  has a pair of sockets  70  that removably receive a pair of cartridges. The right socket latch spring  75  and the left socket latch spring  76  can be formed as leaf springs on a plastic injection molded upper housing  21 . 
     The left interface frame air intake airflow  82  passes through the left metal frame airflow opening  64  of the left cartridge metal frame  62  and the right interface frame air intake airflow  81  passes through the right metal frame airflow opening  65  of the right cartridge metal frame  61 . Airflow passes across the sensors, then through the interface frame  40 , then into the cartridges, through the cartridge chimneys, and then out of the chimney ports to the mouthpieces. 
     As seen in  FIG.  11   , the airflow diagrams shows that the right air intake flow  85  passes across the right airflow sensor, while the left air intake flow  86  passes across the left airflow sensor. The right air intake flow  85  then passes through as the right interface frame air intake airflow  81  through the right metal frame airflow opening  63 . Similarly, the left intake flow  86  passes through as the left interface frame air intake airflow  82  through the left metal frame airflow opening  64 . From the metal frame airflow openings, the air splits into a pair of paths for each cartridge. 
     The right cartridge has a first right intake passage  87 , and a second right intake passage  97 . The left cartridge has a first left intake passage  88 , and a second left intake passage  98 . The first right intake passage connects to a first right bend back passage  89  that turns the airflow from an upward flow to a downward flow. The downward flow then turns back upward at a first right prechamber passage  92 . Similarly, the second right intake passage  97  is generally vertical and receives airflow through the metal frame. The generally vertical airflow of the second right intake passage  97  leads to the second right bend back passage  95  where the upward airflow turns downward to a second right prechamber passage  93 . The second right prechamber passage  93  turns the downward airflow back to an upward airflow. Thus, each of the air intakes on the right cartridge have an upward airflow, then a downward U-shaped bend to an upward U-shaped bend. In all, each airflow passage has five right angle bends. The pair of airflows and the pair of airflow passages are preferably symmetrical and begin distally at a lower end of the cartridge closer to the lower section. The airflows then converge at the right heater  28 . 
     The left intake passages include the first left intake passage  88  which leads upward to the first left bend back passage  90  that bends downwardly toward the chimney. The first left bend back passage  90  leads to a first left prechamber passage which bends upwardly to deliver the airflow to the left heater  29 . The left intake passages are thus similar to the right intake passages. The second left intake passage  98  receives air passing through the interface frame  40 , and directs it upwardly to a second left bend back passage  96  which directs the air downwardly to a second left prechamber passage  94  which has a U-shaped structure and directs the air back to an upward direction to the left heater  29 . 
     The first right prechamber passage  92  has a first right prechamber indent  105 , and the second right prechamber passage has a second right prechamber indent  106 . Similarly, the second left prechamber passage  94  has a second left prechamber indent  107 , and the first left prechamber passage  91  has a first left prechamber indent  108 . The prechamber indents are cavities that are downwardly oriented and may potentially catch lose oil. Similarly, the bend back passages may also have a side indent that is oriented laterally at a 90° angle to the prechamber indents. The bend back passages may catch lose oil if the device is rotated by 90°. Therefore, the first right bend back passage  89  has a first right bend back passage indent, the second right bend back passage  95  has a second right bend back passage indent, the second left bend back passage  96  has a second left bend back passage indent, the first left bend back passage  90  has a first left bend back passage indent. 
     After that airflow passes through the heaters, the air from the right heater  28  passes through the right chimney passage  99 , then the right chimney exit passage  101 , and then exiting the right chimney exhaust  103 , which would pass out of the right mouthpiece opening  18 . Analogously, the left heater  29  exhausts vapor that passes through the left chimney passage  100 , then exiting through the left chimney exit  102 , and then exiting as the left chimney exhaust  104  which would pass out of the left mouthpiece opening  19 . 
     During use, a user can use the right or left cartridge intermittently and alternatively. A user can put a first flavor in a first cartridge and a second flavor in a second cartridge for example. Thus, the user has the benefit of alternating flavor in a single device.
