Description
Technical field
The present invention relates to tobacco heating art, particularly relate to a kind of tobacco heater.
Background technology
Tobacco product, as a kind of special consumer goods, world's consumer goods market occupies sizable proportion.Cigarette type mainly fire-cured tobacco type, mixed type, Turkish tobaccos type and the airing cigarette type produced in the world at present; The principal mode of cigarette is filter tip cigarette.
In recent years, traditional cigarette starts on the problem that affects that is healthy and environment the attention being progressively subject to countries in the world.Tobacco leaf production business is all devoted to the tobacco product providing harm lower to consumer, for this reason, have developed the tobacco product that a kind of mode of can not lighted tobacco by heating carries out aspirating.Because heating-up temperature is far below ignition temperature, therefore effectively can reduces the harmful components that the cracking of tobacco high-temp combustion produces, the chemical constituent burst size of main flume is reduced greatly.Meanwhile, different from the mode that conventional cigarette ignites, heat not burning type tobacco tobacco when aspirating interval and be in not heated condition, therefore, side-stream smoke and environment flue gas also significantly reduce.As the new model of tobacco consumption, heat not burning type tobacco product and be progressively subject to the welcome of Partial Tobacco consumer, just day by day accepted by the cigarette consumption person of most countries.
Such as, but the heater of existing heating not burning type tobacco generally all adopts the mode of the overall heat tobacco of external heat source, is in the Chinese patent literature of 200520130514.5, discloses a kind of tobacco heater at application number.This tobacco heater hypothesis is on water tobacco pipe, this water tobacco pipe comprises one to be had tray point kettle body and one and is erected at kettle and area is less than tray and the tobacco dish put for tobacco with it, this tobacco heater comprises: cover cylinder, one be positioned at handle on the barrel of cover cylinder and a heating unit be arranged on cover cylinder, this heating unit comprises the electrothermal tube in the heating space being arranged on cover cylinder; During use, the tobacco dish being placed with tobacco to stretch in heating space and closes on electrothermal tube, and can heat tobacco in dish when electrothermal tube be energized, the smog produced is by the Smoking pipe sucking-off on water tobacco pipe.Again such as, at application number be 200920006702.5 Chinese patent literature in disclose a kind of tobacco heater.This tobacco heater comprises a Ge Zhaotong mechanism and a heating member; This Zhao Tong mechanism comprises one in order to cover at the outer and cover cap above the tray being located at interval at water pipe of tobacco dish and at least one is installed and to be incorporated on cover cap and can relative to cover cap down projection and change cover cap and down abut against the height adjustment member on tray to heavens; This heating member is installed in cover cap, for generation of the high temperature of heat tobacco.
Owing to adopting the heating of external heat source entirety, heating space is large, need the long period to conduct heat to tobacco itself, therefore which not only wastes energy but also easily cause the uneven and deteriorated of the front and back stage flue gas of heating process.Further, owing to being difficult to by heat conduction to the inside of tobacco, can only effectively heat tobacco be surperficial, therefore the utilization rate of tobacco is lower.In addition, after being used to complete, because high temperature in chamber cannot leave fast, in the process of taking out tobacco, there is the danger of consumer being scalded.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of tobacco heater, for solving the problem that in prior art, tobacco heating requisite space is large, the heat time is long.
For achieving the above object and other relevant objects, the invention provides a kind of tobacco heater, it comprises the housing with cigarette insert port and airflow inlet, and the control circuit be placed in housing and the heater for heating cigarette; Described heater comprises calandria, the heat-conducting piece be wrapped in outside calandria, and be placed in the outer field thermal insulation separation warmware of heat-conducting piece, the heating chamber surrounded by heat-conducting piece is provided with above described calandria, heating chamber is relative to described cigarette insert port to be used for heating cigarette, and be provided with in described heater and run through described calandria and extend to gas channel in described heating chamber from top to bottom, described gas channel is connected with described airflow inlet, above calandria, be provided with temperature sensor, temperature sensor, calandria are all connected with described control circuit; Described housing is also provided with the gauge tap be connected with described control circuit.
Preferably, be also provided with power supply unit in described housing, described power supply unit is electrically connected with described heater by described gauge tap.Further, described power supply unit comprises rechargeable battery.Further, described power supply unit also comprises the charging module be built in described housing be connected with described rechargeable battery.
Preferably, the material of described thermal insulation separation warmware is aerogel blanket, mineral wool, pottery or rock wool.
Preferably, described heating chamber inner surface has lubricious, and coating material is metal, pottery, lucite or composite.
Preferably, described housing is also provided with the display unit be connected with described control circuit.
Preferably, described temperature sensor is the thermistor of positive temperature coefficient or the thermistor of negative temperature coefficient.
As mentioned above, tobacco heater of the present invention, there is following beneficial effect: the air that the present invention adopts heater to come in heated air stream passage, and then adopt the gas after heating to carry out heat tobacco goods (i.e. cigarette), it can realize heat transfer rapidly, the utilization rate of tobacco material is high, the flue gas stable and uniform of release.
