DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0040] The present invention, as seen in FIGS. 1-6, is a cigarette
igniter which includes a rechargeable battery 40 that powers a
heating needle 33 for heating a plant based cigarette 42. The
battery 40 can he recharged by a USB socket 43. The USB socket 43
is formed on the USB board 39.
[0041] The cigarette igniter can have an internal bracket 21 that
holds the battery and heating needle 33 and USB board 39 on a tray
structure that slides into an outer casing 22. The outer casing 22
can be formed as an aluminum sleeve. The internal bracket 21 can
also be made of aluminum for improving heat dissipation. A bracket
cover 23 can cover the internal bracket 21. If the internal bracket
21 is formed as a tray, then the bracket cover 23 can cover the
tray.
[0042] The inner sleeve 24 is formed toward a tip of the cigarette
igniter and has a cigarette opening 44 formed in it. The cigarette
opening 44 receives a plant based cigarette 42. The top cover 25
fits over the inner sleeve 24. The inner sleeve 24 preferably has a
pair of magnets 36 mounted on it that attracts to a magnetic sheet
26 located on the top cover 25. The inner sleeve 24 is preferably
connected to the internal bracket 21 at a lower end of the inner
sleeve 24.
[0043] A second cover 28 is formed as a downward extension of the
first cover 28. The second cover 28 can be formed as a tube that is
connected to the first cover 27 which is formed as a flared flange.
A connecting ring 29 can connect the first cover to the second
cover. Preferably, the connecting ring 29 is a thermal break that
prevents heat from transmitting from the second cover 28 to the
first cover 27.
[0044] A spring 30 is mounted toward a base of the heating needle
33 so that sensor needle tips 34 mounted on heater seats 32 can
detect insertion of a cigarette. Once the cigarette is inserted,
the heating needle 33 begins to heat, and the heat generated
through electrical resistance of the heating needle 33 is held
within the heating chamber 88 by an insulation sleeve 31. The
insulation sleeve 31 forms a thermal break between the heating
portion and the battery 40. The sensor needle tips 34 are contact
switches that are activated when a downward movement of the
cigarette completes a circuit. A control board 38 senses the
circuit completion.
[0045] Additionally, a microphone 41 or other diaphragm pressure
sensor can be electrically connected to the USB board so that the
microphone 41 receives a flow of air or air pressure disturbance
from a microphone opening 50. A user can blow on the microphone.
When the microphone senses air vortices around the bevel 51 of the
microphone opening 50, the control board 38 deactivates the heating
needle 33. Thus, the user can blow on the microphone opening 32
that can deactivate the heating needle 33. The microphone is
preferably held within a microphone holder 52 formed of a soft
plastic that isolates the microphone from the user during use.
Thus, a user can deactivate the cigarette by softly blowing on the
microphone switch. The microphone can be implemented by a diaphragm
pressure sensor or an audio microphone element commonly found in
consumer electronics. The microphone switch is an air activated
deactivation switch that is in a different and separated stream of
air flow than the cigarette. Triggering of the air switch overrides
the cigarette insertion switch so that heating needle 33 turns off
even if the cigarette is inserted. In windy weather, the microphone
opening 50 is shaped so that the user can put a finger over the
microphone opening 50 to cover it from inadvertent wind
deactivation. If the user were to accidentally drop the device, the
rush of air across the microphone opening 50 or the sound of the
impact could deactivate the cigarette to provide a safety
mechanism.
[0046] The microphone may have a thin membrane receiving air
vibrations. The thin membrane is preferably mechanically connected
to a magnet that passes through an electrical coil. The electrical
coil generates a current when the air vibrations vibrate the thin
membrane which in turn vibrates a magnet that passes through the
electrical coil. The membrane can be made of a fabric, or a plastic
sheet. The membrane can be a fabric can be laminated to a plastic
sheet. The membrane is preferably circular and can be thermoformed
to be conical in shape. The membrane can be a thin plastic
laminated sheet that is thermally laminated to the microphone
housing. The electrical current generated from the electrical coil
can activate a transistor that acts as a switch. Thus, the
microphone is formed as an electrical switch for a circuit. The
microphone can be mounted within a bracket formed on the housing.
The bracket can be unitary with the housing and thermoplastic
injection molded.
[0047] The airflow along the bevel 51 generates vortices that the
audio microphone element is attuned to listen to. The control board
38 is connected to the microphone 41 so that the control board 38
can filter out other sounds and pressure disturbances and only pick
up on the air vortices generated when blowing across the bevel 51.
This prevents the device from accidentally deactivating during use.
The bevel 51 can be configured to generate resonance such as
Helmholtz, or can be configured to direct air toward the pressure
sensor.
[0048] An indicator such as an LED on the control board 38 can
indicate to the user the status of the heating needle 33. The LED
can be connected such as by a prism. An example of a prism is the
light guide column 35 that can direct the LED light to the exterior
of the device. The USB board 39 can connect to the control board 38
by a cable for providing data access. The USB socket 43 is formed
in a lower portion of the outer casing 22. Optionally, the
microphone can output audio to the USB port, while at the same time
retaining its properties as a switch.
