Hey all, sorry this took a bit longer than expected, but I haven't seen any other teardown pictures, so here they are. Sorry about the cell phone pictures, my real camera is out of commission at the moment.
Five T6 screws remove the top plate.
Closer view of the inside.
Glass bowl lifts right out, as does the metal plate at the bottom of the bowl. The whole bowl assembly is held together by pressure from the top plate. None of these gaskets are attached, so should be easy to replace if need be, though I don't see why you would need to. The gasket around the screen keeps material out of the inside of the device. I had a little bit of material built up there under the bottom edge of the bowl that had been stopped by the gasket, but that doesn't seem to influence functionality. Doesn't get hot enough there to worry about combustion.
Next that white plate comes out, exposing the heating coil. All the white bits here feel like ceramic, or could just be a different type of (seriously) high-temperature glass.
Since I'm not willing to bend any of the wiring for the heating coil, three T5 screws holding in the circuit board need to be removed next, then it lifts right out.
Close up of the top of the board. Judging by the version number (2.93) on the board, they went though a hell of a lot of revisions to get this right.
And the bottom of the board. You can see the battery connection in the middle there, power switch is at the bottom left, and heating button is on the top.
I can't even imagine what type of metal the heating coil is made of to be able to withstand 50 watts running through it, rapid heat cycling, and such high temperatures in ambient air. Like I said before, light bulbs flame out in seconds without an inert gas protecting them.
