A recently granted patent (Publication Number: US11877597B2) discloses a vaporizing device with a unique design. The device comprises an outer tube surrounding an inner tube, with an annular liquid storage tank between them. A mouthpiece is connected to one end of the inner tube, while a heater coil chamber houses a heater coil and a wick that extends into individual recessed pockets in the liquid storage tank. The heater coil chamber includes upper and lower housing components, with the heater coil positioned between them. The design ensures efficient vaporization of the liquid stored in the tank.

Additionally, the patent also covers a cartomizer for an electronic cigarette, which shares similarities with the vaporizing device. The cartomizer includes an outer tube, an inner tube forming an air path, and an annular liquid storage tank. A heater coil chamber houses a heater coil and a wick that extends into recessed pockets in the liquid storage tank. The design features a rigid inner tube supported at both ends and an absorbent material between the inner tube and the mouthpiece. The unique configuration of the cartomizer allows for effective vaporization of the liquid, providing a satisfying experience for users.
