Balancing substance delivery in vaporizers

Abstract

This disclosure describes control of a personal vaporizer, such as an electronic cigarette, a vape pen, vape kits, e-cig, or e-hookah, electronic nicotine delivery system, that either can be coupled to one or more other personal vaporizers or that has two or more cartridges for vapor generation and delivery. Personal vaporizers can provide controlled substances (e.g., nicotine, Tetrahydrocannabinol (THC), Cannabidiol (CBD), etc.). In addition to the controlled substances, personal vaporizers allow for unique flavors as compared to traditional inhalation devices (e.g., cigarettes, cigars, or pipes). Since cartridges for personal vaporizers often provide a fixed dosage of substance and limited range of flavors, it can be desirable to allow the user to mix and combine multiple cartridges.

 a body comprising:
 a power supply; 
 a first atomization chamber and first chimney configured to deliver atomized substance to a user; 
 a second atomization chamber and second chimney configured to deliver atomized substance to a user; 
 a first sensor, configured to provide a signal associated with airflow through the first atomization chamber; and 
 a controller comprising a communications module, the controller configured to apply current to an actuator in response to the signal from the first sensor and a second signal from a second sensor associated with the second atomization chamber. 
   
     
     
         2 . The personal vaporizer of  claim 1 , comprising:

         3 . The personal vaporizer of  claim 1 , wherein the first sensor and the second sensor are puff sensors. 
     
     
         4 . The personal vaporizer of  claim 1 , wherein the actuator is a heating element. 
     
     
         5 . The personal vaporizer of  claim 1 , wherein the applied current is determined based on a lowest input received from the first sensor and the second sensor. 
     
     
         6 . The personal vaporizer of  claim 1 , wherein the applied current is determined based on an average of the signals received from the first sensor and the second sensor. 
     
     
         7 . The personal vaporizer of  claim 1 , wherein the communications module use an I2C protocol to communicate with the second sensor. 
     
     
         8 . A method for generating atomized substance in a personal vaporizer comprising:
 receiving, from a first sensor associated with a first atomization chamber and a first chimney configured to deliver atomized substance to a user, a first signal from a first sensor, the first signal associated with airflow through the first atomization chamber;   receiving, from a second sensor associated with a second atomization chamber and a second chimney configured to deliver atomized substance to a user, a second signal from a second sensor, the second signal associated with airflow through the second atomization chamber; and   applying, by a controller comprising a communications module, a current to an actuator associated with the first atomization chamber based on the first and second signals.   
     
     
         9 . The method of  claim 8 , wherein the first atomization chamber and the actuator are included in a cartridge that provides a flow path to transport a vaporized substance to a user.

         11 . The method of  claim 8 , wherein the actuator is a heating element. 
     
     
         12 . The method of  claim 8 , wherein the applied current is determined based on a lowest input received from the first sensor and the second sensor. 
     
     
         13 . The method of  claim 8 , wherein the applied current is determined based on an average of the signals received from the first sensor and the second sensor. 
     
     
         14 . The method of  claim 8 , wherein the communications module use an I2C protocol to communicate with the second sensor. 
     
     
         15 . A system for generating atomized substance in a personal vaporizer configured perform operations comprising:
 receive, from a first sensor associated with a first atomization chamber and a first chimney configured to deliver atomized substance to a user, a first signal from a first sensor, the first signal associated with airflow through the first atomization chamber;   receive, from a second sensor associated with a second atomization chamber and a second chimney configured to deliver atomized substance to a user, a second signal from a second sensor, the second signal associated with airflow through the second atomization chamber; and   apply, by a controller comprising a communications module, a current to an actuator associated with the first atomization chamber based on the first and second signals.
