Benefits of technology

The present invention is a vape device that can accurately measure the amount of payload delivered to a user during each inhalation. The device uses multiple methods to determine the dose, including tracking the energy used to vaporize the payload, measuring the temperature and density of the vapor, and analyzing the light intensity transmitted through the vapor. These methods provide more accurate and repeatable results, benefiting both medicinal and recreational users. The device can also determine the size and distribution of droplets in the vapor, which can be used to calculate the total mass of the vapor. The technical effects of this invention include improved dose metering and a better understanding of the effects of different inhalation methods on the user experience.

Problems solved by technology

While there are a few conventional vape devices that attempt to determine the dosage of a vaporized payload delivered to a user, they use inaccurate methods that offer poor dose metering performance.
It is technically difficult to accurately measure the dose administered by a vape device because, for example, vapor density can be inconsistent and operating conditions will vary.
As such, medicinal patients are unsure of the dosage that they have consumed at any given time, which limits the repeatability and efficacy of the drug's effects.
Also, recreational users may experience different effects (desirable and undesirable) depending on dosage.

first embodiment

of Vape Device

[0051]Referring to FIG. 1, a first embodiment of a vape device is shown generally as reference numeral 10. Vape device 10 includes a mouthpiece assembly 12, an atomizer assembly 19, a payload assembly 24, and a control assembly 14. Any of mouthpiece assembly 12, atomizer assembly 19, payload assembly 24, and control assembly 14 may be formed integrally together and included within a common housing suitable for grasping by a user. Further, any of mouthpiece assembly 12, atomizer assembly 19, payload assembly 24, and control assembly 14 may be formed in separate housings that are releasably connected to each other via connecting means 15, which can comprise, for example, one or more of pressure or friction fit connection means, twist mechanical lock means, magnetic connection means and any other connecting means as well known to those skilled in the art. The connecting means 15 may include a female 510 threaded connector on the control assembly 14 that releasably engages...

second embodiment

of Vape Device

[0067]Referring to FIG. 2, a second embodiment of a vape device is shown generally as reference numeral 100. In some embodiments, vape device 100 can comprise control assembly 14, atomizer assembly 79 and mouthpiece assembly 88 operatively coupled together in that order using mechanical connection means 56 to join the subassemblies together. Mechanical connection means 56 can comprise one or more of threaded connection means, magnetic connection means and friction or press-fit connection means, and any of the connection means 15 described above, including 510 threaded connectors. In some embodiments, mouthpiece assembly 88 can comprise a mouthpiece 58 in communication with the outlet of atomizer 20 via conduit 60, which is typically a hollow tube made of stainless steel, aluminum, or other materials known to those skilled in the art. Mouthpiece assembly 88 can further comprise a payload reservoir 62 that can be filled with a payload 64 that may be liquid or oil. The pa...

Abstract

The present invention is directed to a vape device configured to determine the dose of a payload delivered to a user during each of a plurality of user inhalations. In a first embodiment, the vape device tracks the energy used to vaporize a portion of the payload during user inhalation to determine the dose. In a second embodiment, the vape device measures the temperature at multiple locations within the air flow chamber during user inhalation to determine the dose. In a third embodiment, the vape device measures the intensity of light that is transmitted through the vaporized payload, reflected off the vaporized payload, or transmitted through a light transmitting medium positioned within the vaporized payload, during user inhalation to determine the dose. In a fourth embodiment, the vape device utilizes hot wire anemometers to determine the mass of the vaporized payload that was delivered to the user during each user inhalation and / or to determine the size and density distribution of the droplets in the vaporized payload and use such distribution to calculate the total mass of the vaporized payload that was delivered to the user during each user inhalation. The disclosed methods may be used independently, or in any combination, in accordance with the invention.
