Background technique
It include power supply, controller, key control unit, the first heating unit and the second heating in a kind of existing low temperature cigarette
Unit, wherein power supply, key control unit, the first heating unit and the second heating unit are electrically connected with the controller, and first adds
Hot cell is not contacted with cigarette tobacco portion and is heated to cigarette tobacco portion, and the second heating unit is to the sky in low temperature cigarette inlet channel
Gas heating, the first heating unit and the second heating unit collective effect carry out low-temperature bake to the tobacco portion of cigarette, to make it
Smog is generated to suck for user.
Existing this low temperature cigarette heating control system has the disadvantages that：
First, due to being in dry-fire condition when the first heating unit and the work of the second heating unit, thus it is particularly easy to
Damage, and the first heating unit and/or the damage of the second heating unit and when opening a way, user can not learn the situation in time and adopt
Corresponding measure is taken, to influence to use, functional reliability is low；It there is also the case where low temperature cigarette actual power consumption is without smoke, wave
Take the energy.
Second, at the beginning of smoking, needs to heat long period tobacco portion ability smoke and former mouthfuls of amount of smoke are smaller, i.e. smoke
Speed is slow, amount of smoke is unstable, poor user experience.
Summary of the invention
In existing low temperature cigarette, user cannot learn in time whether heating unit damages open circuit, influence using stack velocity
Slowly, amount of smoke is unstable, poor user experience.The purpose of this utility model is that in view of the above shortcomings of the prior art, providing one
The low temperature cigarette heating control system that kind improves can stop working in time when heating unit is damaged and opened a way and remind user, work
Make high reliablity, energy saving；Stack velocity is fast, amount of smoke is stable, and smog is in good taste, and user experience is good.
In order to solve the above technical problems, technical solution used by the utility model is：
A kind of low temperature cigarette heating control system, including power supply, controller, key control unit, the first heating unit and
Two heating units, wherein power supply, key control unit, the first heating unit and the second heating unit are electrically connected with the controller,

Atomization critical-temperature is risen to, but the atomization critical-temperature is insufficient to allow tobacco portion atomization to generate smog.When user starts suction,
Second heating unit starts to work and the air in inlet channel is heated to atomization temperature, these hot-airs pass through tobacco segment
When, tobacco segment absorb hot-air temperature after atomization generate smog sucked for user.
After user's start button control unit, if the first heating unit and the second heating unit are normally connected into circuit,
Controller issues instruction the first heating unit of control and preheats to tobacco portion, during this preheating, due to tobacco portion
Temperature be lower than atomization temperature, thus tobacco portion does not generate smog, when tobacco portion is heated to the preset time or atomization is critical
Keeping warm mode is in after temperature, wherein atomization critical-temperature is preferably 130 DEG C ~ 180 DEG C, more preferably 140 DEG C ~ 170 DEG C.Later
When user's smoking, flow control units, which detect in inlet channel to have air-flow to flow through and will test result, is sent to controller,
Controller issues instruction control the second heating unit work, and the air in inlet channel is heated to after the second heating unit
Atomization temperature（Preferably 230 DEG C ~ 280 DEG C, more preferably 240 DEG C ~ 250 DEG C）, then these hot-airs by tobacco portion and make
Tobacco portion is more than atomization critical-temperature rapidly, to be atomized generation smog.
In the present invention, since tobacco portion has been preheated to atomization critical-temperature by the first heating unit, so
When passing through tobacco portion by the hot-air that the second heating unit heats generate with airflow pattern, tobacco portion absorbs a small amount of heat just
Production smog can be atomized.Simultaneously as hot-air fills each tobacco unit of tobacco portion, each of tobacco portion in smoking
Tobacco unit has been pre-heated to atomization critical-temperature by the first heating unit again, so each tobacco unit of tobacco portion is heated
Uniformly and every mouthful of smoke temperature of production is constant, and smog mouthfeel is more preferable.Further, since have the preheating of the first heating unit, the
