Background

The electric heating atomization technology is a novel atomization technology which is started in recent years, the principle is that heat energy is generated through the heat effect of a resistor, and the heat energy heats and atomizes liquid into atomized steam, so that the electric heating atomization technology is widely applied to medical, intelligent household appliances and consumer electronics products. The atomization device applied to the electronic cigarette industry at present mainly conducts liquid through a liquid guiding medium, and generates heat after the liquid is conducted through a heating body to heat electronic cigarette oil to be evaporated and atomized. Because of the need to ensure that the tobacco tar does not leak from the atomizer and less liquid is required to be heated and atomized at the heating element of the atomizing surface, the liquid often needs to pass through a porous medium to reach the atomizing surface. During the heating atomization process, the viscosity of the tobacco tar can change along with the working time: the room temperature under the initial condition, tobacco tar kinematic viscosity is higher, and conduct on leading liquid and tobacco tar along with the temperature of heating atomizing in-process heat-generating body, the tobacco tar becomes low along with the rising kinematic viscosity of temperature, what its influence is the tobacco tar is at the internal rate of movement of porous drain, the great tobacco tar of kinematic viscosity under especially some normal atmospheric temperature, its normal atmospheric temperature and by the high back velocity of flow change of heating temperature change greatly, can lead to just beginning during operation smog volume little in the atomizing in-process like this, the problem of the core is pasted in the fuel feeding inadequately or appears, cause user experience relatively poor.

In order to improve the situation, in the prior art, when the prior art is improved and designed, micropores are usually enlarged to improve the fluidity of the tobacco tar with poor fluidity, so that the problem of burnt cores caused by insufficient liquid supply is reduced or avoided, but after the micropores are enlarged, the temperature of a heating body is transmitted to the tobacco tar along with the increase of the working time, the viscosity is reduced when the temperature is increased, the fluidity is improved, and the problem of oil leakage is easily caused.

In the other method, in the case of tobacco tar with higher kinematic viscosity, the heating quantity is reduced to reduce the consumption of liquid, so that the liquid needs to be reduced to prevent the core from being burnt dry, but the reduction of the heating quantity can generate less smoke, the atomization is insufficient, and the experience is poor.

Embodiment 1, as shown in fig. 1 to 8, a heat generating mechanism for stepwise heating includes a heat generating circuit 100 for evaporating a liquid, and an electrode 200. The heating circuit 100 comprises a preheating part 120 embedded in the liquid and an atomizing part 110 attached to or embedded in the atomizing surface of the liquid; the preheating part 120 and the atomizing part 110 are connected in series or/and in parallel between the electrodes 200; the preheating part 120 and the atomizing part 110 are overlapped so that their projections are completely overlapped or partially overlapped; or the preheating part 120 and the atomizing part 110 are arranged in high and low order so that their projections do not overlap; at least the atomizing area 110 is of unitary construction and has a shape and size that is compatible with the liquid-conducting atomizing surface.

In the practical application process, as the viscosity of the tobacco tar changes along with the temperature, the initial state is room temperature, the temperature is low, the kinematic viscosity of the tobacco tar is high, the moving speed in the porous liquid guiding body is slow, the amount of the tobacco tar reaching the heating part is small, the smoke amount is small when the porous liquid guiding body starts to work, the appearance is that the oil supply is insufficient, and the core is easy to be burnt. Along with the time, the temperature of the porous liquid guiding body is gradually increased in the atomization process, the moving speed of the tobacco tar in the porous liquid guiding body is accelerated, the amount of the tobacco tar reaching the heating part is increased, and the amount of the smoke is correspondingly increased.

The most direct objects of the invention are: in different time periods from beginning to end, the tobacco tar can be uniformly atomized all the time, and the problem of small smoke amount when the tobacco tar starts to work every time is avoided. The invention is based on the heating circuit 100 of the liquid guiding atomization surface in the prior art, adds a longer heating circuit, keeps the atomization area unchanged, increases preheating, and structurally forms two parts of an atomization part 110 and a preheating part 120, wherein the atomization part 110 is used for atomizing the tobacco tar on the atomization surface, and the preheating part 120 is used for raising the temperature of the liquid guiding body, namely preheating the tobacco tar before reaching the atomization surface, so that the kinematic viscosity of the tobacco tar is lowered, and the tobacco tar can be uniformly atomized in a sufficient amount in different time periods of the atomization process.
