Vaporizer device microfluidic systems and apparatuses

A collector 7313 for a vaporizer cartridge, the collector 7313 comprising a collector body having a controlled fluidic gate 7103 formed into a portion of the collector body, the controlled fluid gate 7103 comprising: a first capillary channel 7105 fluidically coupled to a vent; a second capillary channel 7107 fluidically coupled to a storage chamber; and a high-drive channel 7110 including an upper wall 7116 and a lower wall 7117, the high-drive channel 7110 originating at a third constriction point 7113 and diverging outwardly between the upper wall 7116 and the lower wall 7117 toward the first capillary channel 7105 and the second capillary channel 7107. The collector 7313 further comprises: an overflow channel 7104 extending through and at least partially defined by the collector body, the overflow channel 7104 in fluid communication with the controlled fluidic gate 7103; and a plurality of protrusions extending from one or more surfaces of the overflow channel 7104 to thereby form respective constriction points along the overflow channel 7104, wherein at least two constriction points of the respective constriction points differ in at least one of a size or a shape relative to each other.
