  • the inhalation resistance of the second embodiment increases by 28.7%.
  • a main reason for the small inhalation resistance of the first embodiment is that a cross-sectional area of an inlet channel of the vaporization cavity 214 is relatively large. The local resistance loss of the air entering the vaporization cavity 214 is small, and the airflow channel at the outlet of the vaporization cavity 214 is smoother, generating a small vortex and less resistance loss.
  • a vortex in an area 1 causes an increase in the inhalation resistance of the airflow channel and intensifies condensation of vapor.
  • a vortex in an area 2 causes a vaporization medium to not be taken away in time, and the temperature of the heating element is too high.
  • the two air guide grooves 2121 of the vaporization cavity 214 of the second embodiment are on the same straight line, after the air enters the vaporization cavity 214 from the two air inlets, a "stagnation area" appears at the heating element in the middle, a large vortex (as shown in a dotted box in the foregoing figure) is generated. Most of the airflow is not fully diffused in the vaporization cavity 214, and directly flows out to the air outlet channel.
  • the air guide grooves 2121 of the first embodiment are staggered with each other, so that the air enters the vaporization cavity 214 and fully diffuses. Velocity distribution in a heating element area is more uniform, and the air may be fully mixed with the vaporized liquid vaporization medium and then flow out of the vaporization cavity 214.
  • the airflow in the first embodiment is more uniformly mixed and the flow is smoother.
