Definitions

  • aspects of the present invention relate to portable electronic vaporizing devices for use with vaporizable products.
  • Electronic vaporizers are common place and are generally utilized for the purpose of aroma and/or inhalation therapy.
  • vaporizers heat a substance, herbs for example, such as tobacco, cannabis, lavender, chamomile, and many other types of plant material.
  • the vaporizer may work by heating the substance through the use of direct heat or the use of hot air.
  • the second is thermal radiation in which light is used to heat the substance.
  • the third is convection where hot air is passed over the substance.
  • a mist or vapor containing some aspect of the substance is released and either enjoyed as an aromatic or inhaled to obtain a physiological reaction.
  • the warm air containing the substance product can be harsh on the throat and bronchial tubes. Accordingly, some vaporizers use a cooling down process that allows water moisture to be included in the vapor produced. These vaporizers enable the user to inhale a cool moist vapor that is relatively less harsh and irritating. Vaporizers are often preferred over traditional methods of heating or smoking substances due to the reduction of harsh side effects. Some of these side effects include inhalation of tar, carbon monoxide, and other carcinogens either directly or from second hand smoke.
