  • the embodiment of the present application further provides an atomization device, comprising the above-mentioned heating component 100.
  • the atomizing device provided in the present application based on the above-mentioned heating component 100, has the advantages of rapid formation of atomized gas and low probability of occurrence of dry burning, core burning and odor.
  • the atomizing device further includes a temperature-controlled resistor and a power supply battery.
  • the heating part 21 and the heat-conducting part 22 in the heating component 100 are electrically connected to the power supply battery in parallel, and at the same time, the temperature-controlled resistor is connected in series with the heat-conducting part 22, so as to form a partitioned temperature control circuit.
  • the advantage of the partitioned temperature control circuit is that the heating part 21 and the heat-conducting part 22 are connected in parallel, can be independently controlled, do not interfere with each other, and when the heat-conducting part 22 is working, the temperature-controlled resistor connected in series with it also generates heat due to power-on.
  • the series circuit is short-circuited.
  • the heat-conducting part 22 cannot be powered on to generate heat and is in a stopped state. In this way, the heat generation of the heat-conducting part 22 can be controlled so that it can preheat the atomization of oil and the like, and the heating temperature is not too high to ensure the utilization efficiency of the power supply battery.

Abstract

Sont divulgués dans la présente demande un ensemble chauffage (100) et un dispositif d'atomisation. L'ensemble chauffage (100) comprend un support d'atomisation (10) et un élément chauffant (20). Le support d'atomisation (10) a une partie de préchauffage (11) et une partie d'atomisation (12) ; à la fois la partie de préchauffage (11) et la partie d'atomisation (12) sont en contact avec un liquide à vapoter ; et l'élément chauffant (20) comprend une partie de chauffage (21) et une partie de conduction de chaleur (22), la partie de chauffage (21) étant disposée sur la partie d'atomisation (12) et la partie de conduction de chaleur (22) étant disposée sur la partie de préchauffage (11). Dans l'ensemble chauffage (100) fourni par la présente demande, la partie de préchauffage (11) est conçue pour préchauffer un liquide d'aérosol et la partie d'atomisation (12) est conçue pour atomiser le liquide d'aérosol tel qu'un liquide à vapoter, générant ainsi un phénomène d'atomisation. En conclusion, lorsqu'un liquide à vapoter s'infiltre dans l'ensemble chauffage (100) de la présente demande, la partie de préchauffage (11) peut préchauffer le liquide à vapoter pour améliorer la fluidité du liquide à vapoter, ce qui permet d'éviter les phénomènes de combustion à sec et un noyau brûlé provoqués par une alimentation en liquide à vapoter insuffisante.
