the absorbent material is on the outside of the wire.. the wire simply provides the heat..
the wire wool around the little pot gets soaked in fluid.. the fluid moves into the little pot.. the coil gets soaked in the fluid.. it heats up when puffed on and vaporizers the fluid thats soaked into the material around the hot wire coil..
the cartridge isnt really needed only to replenish the liquid thats soaked into the wire wool around the atomizer pot.. as the coil uses up fluid in the pot more moves into the pot to replace it from the wire wool around the pot..
the things work better when the correct amount of liquid is dripped directly onto the wire wool around the atomizer pot.. they come ready primed from the makers..
all very crude and all very hit and miss.. the liquid dosnt pass from the cart to the wire wool in sufficient quanities to feed the absorbent material around the heater coil.. the coil often dosnt get hot enough and the absorbent material around the hot wire cease to be absorbent after xxxx puffs..
the
batteries are useless cos they aint big enoiugh and die off pretty quickly..
the
devices are not suitable to be used all day and every day to replace a heavy smokers 30 a day type habit..
ruyan didnt design them to do this.. they designd them for occasional use where real smokers couldnt "real" smoke.. used in this way the things work well enough.. used to replace a 30 a day habit they dont work well enough..
the difference between cheaper generics and expensive "brand" names is the price u pay and the "service" u "hope" to get....
being as the things are being miss sold and used for a purpose they are not suitable for the "service" concept isnt practical..
buy cheap and replace often.. or follow the new ruyan lead (throw away cigar) and buy expensive and replace often.. but replace often is the key..
