  • the flow direction of the air flow can be changed by using different shapes of atomizing chambers.
  • the first embodiment has The air flow is smoother, because although the structures of the air inlet adapter section and the air outlet channel 213 are roughly the same in the first embodiment and the second embodiment, the design of the atomizing cavity 214 is different. The main difference is that the air flow is caused by the adapter section.
  • the second connecting part 2142 enters the atomizing cavity 214 with different speed and horizontal angles, and the shape of the transition section (the second connecting part 2142) from the atomizing cavity 214 entering the air outlet channel 213 is different, so that the uniformity of the airflow and the The fluidity is different.

  • the suction resistance of the second embodiment is 918.3Pa.
  • the suction resistance of the second embodiment is increased by 28.7%.
  • the main reason for the low suction resistance in one embodiment is that the cross-sectional area of the inlet channel of the atomizing chamber 214 is large, the local resistance loss of air entering the atomizing chamber 214 is small, the outlet airway of the atomizing chamber 214 is smoother, and the generated vortex is small. , the resistance loss is small.
  • the atomizing chamber 214 of the second embodiment has two large vortex areas.
  • the vortex in the area 1 will increase the suction resistance of the airway and cause the atomization to increase.
  • the gas condensation is intensified, and the vortex in the area 2 will cause the atomization medium to be unable to be taken away in time, and the temperature of the heating element will be too high.
  • the air guide grooves 2121 of the atomizing chamber 214 of the second embodiment are on the same straight line, the air enters the atomizing chamber 214 from the two air inlets respectively, and then enters the atomizing chamber 214 in the middle.
  • a "stagnant area" appears at the position of the heating element, which generates a large vortex (as shown by the dotted box in the above figure).
  • the air guide grooves 2121 of the first embodiment are staggered, so that the air enters the atomizing chamber 214 and diffuses fully, and the velocity distribution in the heating body area is more uniform, which can be fully mixed with the atomizing liquid atomizing medium and then flow out of the atomizing chamber 214. .
