  • Patent number: 11832651
    Abstract: A device resembling a hookah to optimize the vaporization temperature of the combustible substance. The device includes a hookah bowl in addition to a complementary removeable capsule in which the combustible substance is placed. A heat insulator is positioned atop the bowl to prevent the loss of vapor and thermal energy. An electric resistance heating element provides heat energy to vaporize the combustible substance. A power source supplies the voltage needed to power the heating element through a MOSFET. The MOSFET regulates the voltage supplied to the heating element. A pressure sensor relays the pressure reading of the hookah hose to a microcontroller unit. Upon the user's draw from the hose, the microcontroller unit is capable of detecting a pressure difference. Resultantly, the microcontroller regulates the voltage supplied to the heating element through the MOSFET leading to the increase in temperature of said heating element for optimal vaporization.
