Description

Secondary-atomizing device for electronic cigarette

Technical field

The present invention relates to electronic smoke atomizer field more particularly to a kind of secondary-atomizing devices for electronic cigarette.

Background technique

As understanding of the people to conventional cigarette harmfulness is gradually deep, electronic cigarette is produced as a kind of electronics for imitating cigarette Product, by means such as atomizations, after tobacco tar or prepared opium paste etc. are become steam, allowing user to suck has similar taste and sense with traditional cigarette The smog of feel, gradually comes into market.

There are mainly two types of existing electronic smoke atomizers: the first uses the heater of metal wire wrap, and suction is had tobacco tar Drain cotton be wrapped in metallic resistance silk, resistive heater generate high temperature be atomized tobacco tar, some drain cottons are connected with smoke grenade, Continuously supplement tobacco tar；Using potsherd as carrier, the surface of potsherd is equipped with heater layer, makes it to cigarette another kind Core or smoke grenade are heated, and tobacco tar is atomized on the surface of potsherd.Existing electronic smoke atomizer has the disadvantage in that

1, easily there is " quick-fried oil " phenomenon, cause to be atomized insufficient, the aerosol particle diameter difference for being atomized generation is larger, shadow Mouthfeel is rung, and the dosage of tobacco tar is big, waste of resource.

2, power is higher, and existing electronic smoke atomizer common power 5W or more, even up to 100W need frequently to fill Electricity, the consumption energy is more, and leads to the higher and boiling hot mouth of cigarette holder temperature；And the heated easily generation carbonization deposition of high-power lower tobacco tar On resistance wire, lead to the variation of resistance wire resistance value and change the distribution in temperature field, most it is direct influence be exactly tobacco tar atomization Amount cannot be controlled accurately.

3, atomization structure volume is larger, and electrothermal calefactive rate is slower.Such as on based on atomizer of the potsherd as carrier, because The thermal coefficient of ceramic substrate is lower, causes the thermal response of atomizer slower, and user cannot reach in real time when with cigarette holder " smoking " To the effect of sucking condensation aerosol, delay is longer, and user experience is poor.

4, in the process there are the uneven distribution in temperature field, the even dry combustion method of tobacco tar localized hyperthermia causes to add Resistant heating Hot water radiation wire or drain cotton material occur denaturation and fall off and be inhaled into human body together as tobacco tar is atomized the aerosol to be formed, and cause Healthy hidden danger.
