This disclosure relates generally to the field of vaporizers, which may also be referred to as electronic cigarettes.
Electronic cigarettes have recently emerged as a new product for providing nicotine through a smokeless inhalation process. Typically, implementations consist of a power supply (typically a battery) and an atomizing device. In reusable electronic cigarettes the two items are separated into a battery and a cartomizer, to allow the disposal and replacement of a nicotine containing fluid cartomizer while preserving the more costly battery and associated circuitry (microcontroller, switch, etc.) for additional use. In disposable electronic cigarettes, the two items are combined to integrate the functions into one unit that is discarded after either the battery energy or the nicotine containing liquid is exhausted.
The electronic cigarette liquid used to vaporize ingredients such as nicotine is generally a solution of propylene glycol (PG), vegetable glycerin (VG), or polyethylene glycol 400 (PEG400), as well as their mixtures to which a flavor and/or nicotine has been added. The solution is often sold in a bottle (for refilling by the user) or in disposable cartridges or cartomizers. Many different flavors are incorporated into these liquids, including those that resemble the taste of regular tobacco, menthol, vanilla, coffee, cola and/or various fruits. Various nicotine concentrations are also available, and nicotine-free solutions are also common.
The following presents a simplified summary of the disclosure in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is intended to neither identify key or critical elements of the invention nor delineate the scope of the invention.

With reference now to the figures, an embodiment of a vaporizer 100 with a removable vaporizer sleeve 200 are illustrated. Vaporizer 100 may include a battery portion 100A and a cartomizer 100B. In some embodiments, cartomizer 100B may share a common housing with battery portion 100A, however the illustrated embodiment shows battery portion 100A as removably connectable with cartomizer 100B.
Battery portion may have a first distal end 102 and a second proximate end 104. Cartomizer may have a first battery-side end 106 and a second mouthpiece-side end 108, and battery portion 100A and cartomizer 100B may be connectable at proximate end 104 and battery-side end 106. Battery portion 100A and cartomizer 100B may be connectable by an known or to be developed connectors, including as illustrated matable male and female threading. Battery portion 100A may include an outer battery shell 110A having a diameter similar, or nearly identical, as the diameter of an outer cartomizer shell 110B. Accordingly, when battery portion 100A and cartomizer 100B are mated, vaporizer 100 may be substantially elongate and cylindrical. In some embodiments, the diameter of vaporizer 100 is approximately 9 mm.
Battery portion 100A may include a variety of components housed within outer shell 110A. One such component may be a rechargeable battery 112, which in one embodiment is a lithium-ion battery. A pressure switch 114 and a printed circuit board (PCB) 116 may also be housed within outer shell 110A. Electronic circuity may be further provided in order to electrically connect battery 112, pressure switch 114, and PCB 116 as part of the operation of vaporizer 100. At least one air hole 118 may be provided on outer shell 110, proximate to either end of battery portion 100A, with at least one additional air hole (not illustrated) provided on or proximate to proximate end 104 in order to establish internal air flow through battery portion 100A. The at least one additional air hole may be in fluid communication with at least one battery-side air hole (not illustrated) provided on cartomizer 100B, which in turn may be fluidly communicable with a tube 122 passing through cartomizer 100B. The tube may terminate at a mouthpiece 124 provided at or proximate to the mouthpiece-side end 108 of cartomizer 100B. Accordingly, when a user inhales through mouthpiece 124, an air flow is generated from air hole 118, through the at least one additional air holes and battery-side end air holes, and further through tube 122, terminating at mouthpiece. Upon establishing this airflow, pressure switch 114 may identify a pressure differential generated from this airflow, which may in turn activate vaporizer 100. In order to facilitate pressure switch 114 in detecting a pressure differential, pressure switch 114 may be held or encapsulated in an compressible or elastic material 126, which in one embodiment is rubber or an elastomer, thereby preventing air from flowing around pressure switch 114.
After detecting a pressure differential, pressure switch 114 may communicate with PCB 116 in order to activate vaporizer 100. As may be controlled by a program operating on PCB 116, upon detection of a pressure differential a current may be sent through the electronic circuitry to a heating element 128 provided in cartomizer 100B. Heating element 128 may be any known or to be discovered material which elevates in temperature once a current passed through the material, and in one embodiment heating element 128 may be substantially composed of nichrome wire. Heating element may be provided within proximity to a storage component 130 for a vaporizable substance, such that heating element may elevate the temperature of a vaporizable substance stored in the storage component 130 to a vaporization temperature, at which point the vaporizable substance may become a gaseous form inhalable by the user through tube 122 and mouthpiece 124. In some embodiments, storage component includes a porous material, such as fiber bating, which may be soaked with a liquid vaporizable fluid. A wick, connected with or otherwise in communication with storage component 130, may be intertwined with heating element 128 in order to facilitate delivery of vaporizable fluid to heating element 128.
PCB 116 may include a series of illuminable indicators 132, which in some embodiments may be light emitting diodes (LED). In the illustrated embodiment, a series of five (5) LED indicators 132 are provided. A series of holes in outer shell 110A may be provided so that indicators 132 are externally viewable. PCB 116 may further operate to detect voltage remaining of battery 112, such that the LED lights 132 may illuminate depending on the voltage remaining. For instance, if battery 112 operates with 4.1V or more, all five indicators 132 may illuminate, however as the voltage drops only a subset of indicators may illuminate. In some embodiments, if battery 112 has less than 4.1V, only four indicators illuminate; if less than 3.9V, only three indicators illuminate; if less than 3.7V, only two indicators illuminate; if less than 3.5V, only one indicator illuminates; and if less 3.3V, no indicators illuminate. Other pre-determined voltage levels may be used depending on factors, such as battery type and power required to operate vaporizer 100. Further components of PCB 116 may include a microcontroller for executing one or more control programs, output transistor and various passive components, embodiments of which are illustrated in
Vaporizer sleeve 200 may be dimensioned to conform with the dimensions of cartomizer 100B such that sleeve 200 may slide over and cover cartomizer 100B. Sleeve 200 may be slightly longer than cartomizer 100B and, as such, may be held into place by retaining ring 134 provided about battery portion 110A at or near proximate end 104. Retaining ring 134 may operate to press against the inner surface of sleeve 200, thereby holding sleeve 200 in place from frictional force. Retaining ring 134 may be embedded in a recess in outer shell 110A, thereby maintaining the position of retaining ring 134. Sleeve 200 may further include a mouthpiece hole 206 which may be aligned with mouthpiece 124 once sleeve 200 is placed over cartomizer 100B. In some embodiments, sleeve 200 and outer shell 110A may include a complimentary motif or design.
