Description

Electronic Smoking Device
Field of the Invention
The present invention relates to electronic smoking devices.
More particularly, but not exclusively, the present invention concerns electronic cigarettes comprising a computer.
Background cf the Invention
It is well known that smoking tobacco is bad for your health and reduces your life expectancy. Smokers have an increased chance of developing lung cancer, suffering from chronic obstructive pulmonary disease and having heart attacks.
However, smokers can find it difficult to quit smoking because they are addicted to the nicotine found in tobacco. A number of smoking cessation techniques have been developed to help people quit, including the use of Nicotine Replacement Therapy (NET) to introduce nicotine into the body in a form other than tobacco. NRT products include nicotine gums, nicotine patches and electronic smoking devices.
Electronic smoking devices are popular because they replicate the smoking habit. These devices are typically cigarette-sized and function by allowing a user to inhale a nicotine vapour from a liquid store by applying a suction force to a mouthpiece. Some electronic smoking devices have an airflow sensor that activates when a user applies the suction force and causes a beater coil to beat up and vaporise the liquid.
Electronic smoking devices include electronic cigarettes.

Description of the Preferred Embodiments
Referring to Figures 1 to 3 there is shown an electronic smoking device having a mouthpiece 2 and a cigarette body 4.
The electronic smoking device is shaped like a conventional cigaratte and both the mouthpiece 2 and cigarette body 4 are cylindrical. The mouthpiece 2 is attachable to the cigarette body at a first end and has an air outlet 6 at a second end.
The cigarette body 2 is a battery assembly 8 and contains a power cell 10 connected to a computer 12 on a circuit board 14.
The computer 12 has a computer processor 16, a memory 18 and input-output means 20. In this example the computer 12 is a microcontroller.
The mouthpiece 2 contains a liquid bottle and a vaporiser 24 having a heater coil 26. The mouthpiece 2 is attachable to the battery assembly 8 by a screw thread that connects a first battery assembly terminal 28 to a first vaporiser terminal 30 and a second battery assembly terminal 32 to a second vaporiser terminal 34.
In use, the power cell 10 has charge and provides power to the computer 12. To maximise the lifetime of the charge in the power cell 10, the computer 12 is configured to detect whether the vaporiser 24 is connected to the battery assembly 8. If the vaporiser 24 is not connected the computer 12 is configured to enter a low power sleep mode. If the vaporiser 24 is connected the computer 12 is configured to enter a higher power connected mode. The computer 12 has a computer program stored in its memory 18 and accessed by its computer processor 16. The connent on state s sensed by the nput-output means 20.
Tn order to conserve power in the power cell 10, the computer 12 sends a pulse to the battery assembly terminals and determines if the vaporiser 24 is attached. If the vaporiser 24 is not attached the computer 12 goes into sleep mode for two seconds during which time no processing takes place and minimal power is consumer. After the sleep time, the computer 12 wakes and immediately and quickly checks again for a vaporiser connection. Again, if the vaporiser is not connected the computer 12 goes into sleep mode for another two seconds. The time that the computer 12 is awake is extremely short compared to the sleep time so the circuit remains predominantly in a low power mode, thus conserving power. During the sleep time no checks are made to determine whether the vaporiser 24 is attached however a user would take several seconds to assembly the device so the vaporiser 24 connection would be easily established by the computer 12 before use of the device by a user.
Figures 4 to 6 show another example of an electronic smoking device. This device is similar to that shown in Figures 1 to 3, however in this example the vaporiser 24 does not form part of the mouthpiece 2. The mouthpiece 2 contains a liquid bottle 22 and is attachable to the vaporiser 24. The vaporiser 24 has a heater coil 26 and additionally a wick 36. when the mouthpiece 2 is attached to the vaporiser 24 the wick 36 acts to communicate liquid from the liquid container 22 onto the vaporiser 24. To interaction between the vaporiser 24 and the battery assembly 8 to conserve power is as described above.
Examples of how the vaporiser 24 is detected by the computer 12 are now described with reference to Figures 7 to 10.
Figure 7 shows a battery assembly 8 similar to that shown in Figure 3 and Figure 6, additionally comprising a capacitor 38.
The capacitor 38 is arranged in a circut such that ft is in parallel to the battery assembly terminals. To test whether the vaporiser 24 is connected to the battery assenlly 8, the computer first charges the capacitor 38, then waits a short time and checks the charge of the capacitor 38. If the vaporiser 24 is connected, the resistance of the vaporiser 24 causes the capacitor 38 to discharge quickly so the computer 12 measures a discharged capacitor 38. If the vaporiser 24 is not connected the capacitor is not fully discharged when checked by the computer 12. Figure 8 shows an arrangement similar to that shown in Figure 7, additionally comprising a resistor 40 in series with the capacitor 38.
In the example shown in Figure 9 and Figure 10, a battery assembly 8 further comprises a transistor 42. To test whether the vaporiser 24 is connected, the computer 12 sends a square wave pulse to the transistor 42. The transistor 42 supplies current to the capacitor 38 for a period of time equal to the width of the pulse, thereby charging the capacitor 38. As described above, if the vaporiser 24 is connected the computer 12 measures a discharged capacitor 38.
Although examples have been shown and described it will be appreciated by those skilled in the art that various changes and modifications might be made without departing from the scope of the Invention. The sleep time is not restricted to 2 seconds and other suitable values could be used. A computer such as a microcontroller could utilise a watchdog timer to implement the sleep time wait in the low power mode. The device is not restricted to being cigarette shaped. The computer is not restricted being a microcontroller and could be fabricated from separate processor, memory and input-output components.
The vaporisers described are examples only.
