The atomizer of the present embodiment is particularly useful for generating smoke, and can be used in various fields, such as medical fields, electronic cigarette fields, and the like. When the atomizer of the present embodiment is applied to the medical field, the substance to be atomized stored in the liquid storage chamber 31 may be a health care medicine, a therapeutic medicine, etc.; when being applied to the electron cigarette field with the atomizer of this embodiment, the material of treating atomizing of saving in stock solution chamber 31 can be the lower liquid tobacco tar of viscosity, also can be the higher liquid of viscosity, semi-solid state or solid-state tobacco tar.

In this embodiment, when concrete implementation, for the convenience with atomizing core 6 and stock solution chamber 31 communicate to atomizing in making the material of treating in the stock solution chamber 31 to atomize in can permeating atomizing core 6 smoothly, can set up a plurality of feed liquor holes 44 that are linked together with stock solution chamber 31 on the lateral wall of outer sleeve 4, and make the outer wall of atomizing core 6 shelter from feed liquor hole 44.

In the present embodiment, the working principle of the atomizer is as follows:

when the higher material of treating atomizing of viscidity atomizes in needs to stock solution chamber 31, the heat that the usable subassembly 5 that preheats produced comes to preheat the higher material of treating atomizing of viscidity, make the viscidity of the material of treating atomizing reduce, the mobility reinforcing, the material of treating atomizing after preheating can permeate to atomizing core 6 fast and by atomizing core 6 heating atomization, form the smog that can supply the user to aspirate, when the user sucks the action through suction nozzle 1, can form the air current on inlet channel 21 to outlet channel 11's circulation route, the produced smog of atomizing core 6 is taken away to the air current and finally discharges through suction nozzle 1, supply the user to inhale and eat.

Based on the above structural design, the atomizer of this embodiment has following technological effect:
