## Title
Electronic rechargeable smoking unit

## Abstract

Electronic Rechargeable Smoking Unit is a fully self-contained device for smoking tobacco. The Unit uses an electrically heated element in addition to oxygen that is induced by inhalation on the Unit to combust the tobacco that is placed within the chamber. No oxygen can be induced without the user inhaling through the mouthpiece. Therefore, the tobacco only burns whilest the user is inhaling resulting in all the smoke from the tobacco passing through the lungs of the user. There is a replaceable/reusable filter placed between the burn chamber and the mouthpiece. The Unit also comes with a hose that can be attached to the mouthpiece as an extension tube. The mouthpiece of the hose contains a switch to control the circuit.

## Background
The present invention relates to an electronic cigarette.
SUMMARY OF THE INVENTION
An electronic cigarette described and claimed in this patent application is a new invention that will reduce the amount of tobacco needed for a consumer to gain the full benefits of a cigarette. It will also reduce second hand smoke as well as the environmental impact on the tobacco grower.
This invention adopts a brand new technical solution to create a device that does not resembles a conventional cigarette and the cigarette smoking process. The electronic cigarette is designed so that the user can smoke regular tobacco in all weather conditions. Its fully enclosed weather protected casing is designed so that the smoker can smoke in rain, wind, and in extreme conditions. The cylindrical attachment is an additional piece that comprises of a 90 cm long plastic tube with electrical wire running inside of it with 2 reed switches on the mouthpiece. The plastic tube is simply placed over the mouthpiece of the stand alone unit and therefore becomes part of 1 unit device. With the additional plastic tubing attached the user can smoke hands free. All that is required is for the user to bite down on the mouthpiece and the 2 reed switches will separate and thus close the circuit and turn on the device.

FIG. 1 The power source of this unit is 4 AA NiMH batteries FIG. 1 (1) that can be recharged via the charging port (4). When the system is activated by the trigger switch (3) the power from the batteries will be supplied through the P-Channel MOSFET (12), 5 micro-henry Inductor (13) and connector (10) to the heating element load (11). The MOSFET (12) is controlled by a step down voltage regulator controller chip (7), in this design a TI TPS64202. The remaining components are required for proper function of the voltage regulator design. 10 micro-farad Capacitors (5) and 47 microfarad capacitor (18) provide filtering. 100,000 ohm Resistor (6) is used to shut off the regulator, and when it is shorted by switch (3) the system is activated. Parallel 100 k ohm resistor (8) and 0.033 ohm resistor (9) are used by controller chip (7) to measure the current in the nickel chrome wire heater (11). Silicon RF Schoottky Diode for Mixer Applications in the VHF/UHF range (20). 4.7 microfarad Capacitor (14) filters feedback voltage from resistor divider formed by the series connection of 150,000 ohm resistors (15) and (17). 680,000 ohm Potentiometer (16) allows for adjustment of the output voltage. Voltage controller (7) uses this voltage to control output voltage applied to heater (11). Led (19) and its associated 270 ohm resistor (21) provide visible indication that the heater (11) is active. Zero ohm Resistor (2) is used for debugging purposes and is not relevant to the function of the design.
Specifications of the Device.
The complete device FIG. 2 measures 2.6 cm wide 8.0 cm in height and 6.5 cm in length.

FIG. 3 (8) is the heating element.
The mouthpiece FIG. 2 (1) is cylindrical 1.5 cm in height and 0.5 cm wide in its opening.
The top cover FIG. 3. (7) is 7.0 cm in length whereby the hinge is 0.5 cm long 2.5 cm wide and 1.1 cm in height. It holds FIG. 3. (5) and FIG. 3 (6) and FIG. 3 (4).
The cylindrical tube FIG. 4 (1) measures 90 cm long plastic tube with electrical wire running inside of it with 2 reed switches FIG. 4 (2) on the mouth piece.
The circuit board power is made up of a 2 layer board.
