Description
Technical field
The utility model is related to tobacco heating art, especially a kind of to heat cigarette for dry type with accurate adjustment temperature
The cavity adjustable type intelligent temperature control dry type low-temperature heat life cigarette device of grass and smog produced by collection.
Background technology
In recent years, even decline as the sales volume of conventional tobacco products occurs stagnating in some developed country markets, and
Many state's public places in Nan Chong ban on opium-smoking and the opium trade dynamics is continued to increase, and novel tobacco product is just in rapid rising.At present, novel tobacco is main
There are 3 major classes, smoke-free tobacco product, low temperature cigarette, electronic cigarette.Wherein, smoke-free tobacco product refer to without combustion process simultaneously
The tobacco product of consumption is sucked by oral cavity or nasal cavity, from usage behavior for, refer to the tobacco that non-suction mode is used
Product.Smoke-free tobacco product mainly by mouth containing, is sucked, and the mode of chewing tobacco provides the consumer with satisfaction, including mouth
Containing cigarette, snuff, chewing tobacco etc.；Low temperature cigarette outward appearance is similar with traditional cigarette, and not burning tobacco is only heated below 500 degrees Celsius,
But satisfaction and Partial Tobacco fragrance can be passed to consumer, burning type cigarette does not reduce tobacco high-temp combustion for this heating
The harmful components for producing are cracked, main flume chemical constituent burst size is substantially reduced.Meanwhile, glowed difference with conventional cigarette,
Its pipe tobacco when interval is aspirated is in non-burning/non-heated state, therefore side-stream smoke and environment flue gas are also greatly lowered.Press
According to the difference of heating source, heating non-combustion-type tobacco product can be divided into electric heating type tobacco product, combustion heating type tobacco product
With physical and chemical reaction hot type tobacco product；Electronic cigarette is, by the solution atomization containing nicotine, by pulmonary absorption, to obtain consumer
The satisfaction for sucking traditional cigarette must be similar to.Compared with common cigarette, electronic cigarette without tar, without carbon monoxide, carbon dioxide,
The harmful substances such as hydrogen cyanide, methacrylaldehyde, arsenic, lead, mercury, so will not be caused any harm to smoker.In addition, nicotine solution is passed through
Vapour colloidal sol is formed after atomization, vapour colloidal sol is diluted rapidly in atmosphere, and low-density vapour colloidal sol is difficult to be absorbed again, also will not shape
Into second-hand-cigarette.Therefore, the health of electronic cigarette not entail dangers to smoker, while will not also endanger the health of people around.Novel tobacco
Product generally has following some principal characters：One is to burn, greatly reduce because burning produce tar and be harmful into
Point, it is smaller compared to traditional cigarette harmfulness；Two is that will not produce second-hand flue gas, influence will not be produced on PE, certain
The contradiction of smoking and public place ban on opium-smoking and the opium trade is alleviated in degree；Three is the physiology that can to a certain extent adapt to and meet consumer
Need.
Novel tobacco product is the emerging strategic product of tobacco industry, and Development of Novel tobacco product is concerning industry future
The Major Strategic problem of development.With novel tobacco product market demand rapid growth and increasing tobacco leaf production factory
Business is devoted to the research and development of the smaller novel tobacco product of harmfulness, as representative novel tobacco product, only heats not
The low temperature cigarette of burning type starts gradually to receive more and more attention.However, the existing heater for heating not burning tobacco
Typically heated using single thermal source, external heat source is not separated and independent control, while to the measurement of temperature also less
Accurately, also uncontrollable heating cavity is collected for produced smog without reasonable, effective, convenient.

Tobacco heating mechanism, including closed cover, heating and power line, external power is connected by power line, heats electric heating
Silk produces flue gas so as to heat tobacco.
Again for example, in the Chinese patent literature of Application No. 201410822140.7, disclosing a kind of tobacco heater,
Including the shell with cigarette insert port and airflow inlet, and the control circuit that is placed in shell and for heat cigarette plus
Hot device, wherein heater include calandria, are wrapped in the external heat-conducting piece of heating, and the insulation for being placed in heat-conducting piece outer layer
Part, there is the heating chamber surrounded by heat-conducting piece above calandria, the equipment by make heating chamber it is relative with cigarette insert port so as to
Tobacco product is heated using the gas after heating, and operating temperature range is between 150 DEG C to 600 DEG C.
Because heating-up temperature has larger thermal inertia, cause in heating process actual temperature can be at the design temperature on
Lower swing so that heating cavity temperature it is unstable, the flue gas produced by the front and rear stage is uneven.Meanwhile, external heat source distribution
Uneven and entirety controls meeting and causes tobacco to be heated not exclusively, and utilization ratio of tobacco is relatively low.In addition, tobacco heating mechanism and being contained
The integration for putting tobacco device is not easy to be collected smog so as to be analyzed detection.
