Definitions

  • the present disclosure relates generally to vaporizers and more specifically relates to vaporizers for converting oil to a mist for inhalation by a user.
  • a vaporizer can be used to convert oil or another substance, such as a substance that contains medication or other compounds, to a vapor or mist for inhalation by a user.
  • Oils can be used to prevent damage to medications that may be sensitive to solvents or propellants used in applications like asthma inhalers, or for medications or compounds that cannot be dissolved in water.
  • at least some conventional vaporizers may suffer from one or more shortcomings, such as burning or carbonization of the oil, excessive wicking, leaking, or clogging. For example, burning or carbonization of oil may occur when a supply of oil is locally depleted relative to a heating coil, which can allow the coil in the area of depletion to overheat, which can include becoming red hot.
  • At least some conventional vaporizers include wicking devices for transferring oil from the storage reservoir to an area for contact with the heating element.
  • wicking devices can result in leaking of oil from the vaporizer, such as onto a user’s hand or clothing.
  • Excessive wicking can fowl a heating element, such as by providing too much fluid to heat to the vaporization point.
  • Excessive wicking may also clog air channels within the device or leave oil exposed to air, which may result in malfunctions or, e.g., allow volatile medication dissolved in the oil to evaporate.
  • such evaporation may cause the oil’s viscosity to change to a point that prevents the oil from being re-liquefied or vaporized within the device. Excessive wicking and clogging may lead to the loss of some or all of the oil contained in the vaporizer, or even render the vaporizer inoperable such that repair or replacement may be needed.
  • the oil used in the vaporizer can be corrosive (e.g., having a PH between 8 and 11.5) and may come into contact with metal parts within the device, which can result in a metallic taste that may be undesirable to some users.

Abstract

L'invention concerne un vaporisateur qui peut comprendre un réservoir pour contenir de l'huile, une chambre pour contenir de la vapeur, un dispositif d'alimentation pour alimenter la chambre en huile venant du réservoir, et un dispositif de chauffage pour chauffer l'huile. Un dispositif d'alimentation peut être conçu pour alimenter la chambre en huile venant du réservoir par action capillaire. Un vaporisateur peut comprendre un bouchon couplé de manière étanche au réservoir et conçu pour coulisser par rapport à au moins une partie du réservoir. Un dispositif de chauffage peut comprendre au moins un élément parmi un laser, un dispositif de chauffage à résistance, un fil, une bobine, un fil au moins partiellement disposé dans un boîtier, et une combinaison de ceux-ci. Un vaporisateur peut comprendre un dispositif de commande et peut être conçu pour chauffer un dispositif de chauffage à une première température pendant une première période de temps, réduire la température du dispositif de chauffage, et maintenir le dispositif de chauffage à une seconde température pendant une seconde période de temps.
