Disclosed is a vaping pen apparatus device for facilitating the smoking of substances containing extracts of cannabis, replacing the cigarette and other artisanal articles which are conventionally used to send the smoke from such extracts into a perforated container without the second-hand smoke of the conventional cigarette/burner.
Referring to FIG.1A and FIG.1B, isometric views of a first example configuration of the electronic vaping device 100 of the present disclosure are shown.
Specifically, FIG.1A shows the device 100 in an exploded state and FIG.1B
shows the device 100 in an assembled state.

4 As can be seen, the device 100 is comprised of a handle 102 with a long thin body, the handle 102 has an indent 104 for receiving a power unit 106 such as a rechargeable lithium polymer battery that powers the device. If the power unit is a rechargeable battery then the device 100 will further comprise a charging port such as a USB port and associated charging circuitry.
The device 100 further comprises a heating tip assembly 108 that in the present example configuration is detachable from the handle body 102, and which houses a heating element 110 for burning/vaporising a substance to be vaped.
The heating element 110 is an enclosure/container that sits in the housing 112 of the heating tip assembly and which contains a resistive coil which is connected to the power unit via a switch (not shown).
The switch is operated by a button 114 located on the exterior of the handle and slightly away from the heating tip assembly. When the button 114 is pressed the switch may connect the resistive coil inside the heating element to the power supply from the power unit 106, causing the coil to rapidly heat.
The container is filled with a conductive material such as magnesium oxide to facilitate the conduction of the heat form the coil to an exterior surface 116 of the heating element 110 which acts as a platform upon which a substance to be burned by the device can be rested.
The surface 116 may be flat, or concave. For example, the heated element 110 may be press-fit into an opening of the housing of the heating tip assembly causing the edges of the surface 116 to be raised. The surface 116 may also be coated with Teflon/PTFE or some other non-stick coating to prevent any residue from burned substances adhering to the surface.
The resistive coil is generally made from a nickel alloy such as nickel chrome, and an example thickness of the wire would be 0.35mm. Generally, a Cannabinoid substance will burn at between 190 and 220 degrees centigrade, therefore the coil should be designed in coordination with the power unit and other circuit components to reach and stay at this temperature while current flows.
In order to withstand the heat regularly the housing of the device may be partially formed of temperature resistant plastics or ceramic.

The disclosed configuration of a long thin body and handle 102 with a button 114 which is placed away from the tip where a substance is to be burned facilitates insertion of the heating assembly tip into an opening of a glass container.
Thus, referring to FIG.2, an isometric view is shown of the insertion of the device 100 into a side opening 202 of a glass container 200 during use, with a substance 300 to be burned/vaporized placed on the surface 116.
The container 200 may be as illustrated a simple glass bottle with an opening 202 for receiving the tip of the device 100 in a side wall and another re-sealable opening for releasing any captured vapours, i.e. the normal bottle opening 204.
In other examples the container 200 could be a bong apparatus specifically designed to function in combination with the disclosed device, and the container 200 and device may be provided together as a kit.
Referring to FIG.3A and FIG.3B, isometric views are shown of the device 100 in use in combination with a glass bottle 200.
Specifically, FIG.3A shows the device 100 vaporizing the substance 300 and emitting the vapours into the glass container 200 through the opening 202, and FIG.3B shows the emitted vapours being released through a second opening 204 of the glass container for inhalation by a user.
The resistive coil is connected to the power unit via a switch such that activating the switch causes the resistive coil to heat to a pre-determined temperature range and conduct the heat to the exterior surface of the enclosure to vaporize or burn a substance resting thereon.
An optional safety feature which may be included with the device design is the inclusion of a sensor or trigger for automatically breaking the circuit, specifically the connection between the power unit and the resistive coil, if it is detected that the temperature of the resistive coil has exceeded a predetermined threshold.
In some examples an electronic heat sensor may carry out this function, consisting of the sensor itself which is in contact with the coil or a conductive element connected to the coil, and a feedback loop which allow the sensor to determine that a threshold temperature has been exceeded and break the circuit.

Alternatively, a "mechanical sensor" may be used such as a bi-metallic switch configured to break the connection when a predetermined threshold temperature is reached.
Such switches consist of a double-sided metallic strip consisting of two metals with different strips of metal with different expansion vs temperature profiles, for example brass and steel, such that when heated, the brass expands more than the steel and the strip curves with the brass on the outside.
If the strip is cooled, it curves with the steel on outside and can be used in thermostat, as a switch or in metal thermometers.
Referring to FIG.4A, an isometric view is shown of an example configuration of a heating tip assembly 108 in an exploded state which incorporates a bi-metallic switch 400 below the enclosure of the heating element 110 and which is connected in series between the coil and the power unit 106 to automatically disconnect the resistive coil 118 of the device from the power unit if the temperature exceeds a predetermined threshold.
Also shown in the exploded state of the assembly 108 is that the housing 112 also contains heat-resistant plastic/ceramic insulation elements 120 for holding the heating element 110.
Referring to FIG.4B an enlarged view of a suitable bi-metallic switch 400 is shown in two situations.
In situation 1, the strip 402, which is formed of two strips of metals having different expansion v temperature profiles, is shown bridging the gap between two wires 404 and has not exceeded the threshold temperature so is flat. One end of the strip 402 is freely moveable and when flat such as in situation 1, connects two pads 406 to form a contact point.
In situation 2, the threshold temperature for the strip 402 has been exceeded, causing the metal on the underside with a lower expansion v temperature profile to expand, bending the entire strip 402 upwards and breaking contact point 406 to break the circuit.
