Description

A kind of electric heating type cigarette with a plurality of destructive distillation chamber

Technical field

The utility model belongs to electric heating type cigarette field.

Background technology

Traditional cigarette satisfies the demands of consumers by lighting pipe tobacco generation flue gas.Yet pipe tobacco ignition temperature is generally 900 ℃ of left and right, in combustion process, can produce the flue gas that contains in a large number bio-toxicity and harmful chemical component (as polycyclic aromatic hydrocarbon constituents), except harm humans health, also can cause environmental pollution.Research shows, nicotine and most tobacco flavor composition (are usually less than 500 ℃) and just can transfer in flue gas at lower temperature, therefore can not produce cigarette because of harmful substance and side-stream smoke that high-temp combustion produces, can significantly reduce cigarette to the harm of health and the pollution to environment.Nearest decades, world Ge great tobacco company is all at Development of New Generation tobacco product or substitute of tobacco, and hope can reduce the harm that tobacco brings to greatest extent meeting on the basis of consumer demand.Low temperature cigarette is by heating (being usually less than 500 ℃) but not burning tobacco, and the fragrance matter toasting in tobacco satisfies the demands of consumers, and is one of important development direction of following tobacco business.

In three kinds of conventional mode of heatings, electric-heating technology is relatively ripe, uses very extensive at present.But general electrical heating conventionally adopts in cigarette the mode of zone of heating is around set; heat from outside to inside tobacco; therefore often there will be the carbonization of outer pipe tobacco and internal layer pipe tobacco also not pipe tobacco such as heating grade heat uneven situation; waste resource; reduced the utilization rate of cigarette; and smoker often feels that flue gas is charred taste, affect smoking and experience.

Utility model content

The purpose of this utility model is the deficiency existing in order to solve above-mentioned background technology, and a kind of composite electric heating type low temperature cigarette is provided, and significantly increases cigarette heating surface (area) (HS, pipe tobacco is carried out to homogeneous heating and produce flue gas, improves pipe tobacco utilization rate.

The utility model proposes a kind of electric heating type cigarette with a plurality of destructive distillation chamber, wherein bringing-up section 3 comprises cartridge heater 31 and this cartridge heater 31 is separated into a plurality of interior heating plate 32 in several destructive distillation chambeies.In wherein said destructive distillation chamber for holding tobacco product, described tobacco product is pipe tobacco, tobacco leaf, reconstituted tobacco, expanded cut stem and composite form thereof, or adds pipe tobacco, tobacco leaf, reconstituted tobacco, expanded cut stem and the composite form thereof of the additives such as tobacco extract and Alevaire and essence and flavoring agent.Wherein in each, heating plate 32 is provided with at least one venthole 36, for heating the circulation of the smog of tobacco product generation.The diameter of described venthole is 0.3-2mm.The number of described interior heating plate 32 can be determined as the case may be, is generally 4-7.

The electric heating type cigarette with a plurality of destructive distillation chamber of the present utility model also comprises fillter section 4 and the cigarette holder 5 with described bringing-up section 3 airflow connections, and the cell section 1 of powering to described bringing-up section 3; Between cell section 1 and bringing-up section 3, be provided with changeover portion 2.In preferred embodiments, described cartridge heater 31 outsides also arrange thermal insulation layer 34, to reduce the temperature of shell, prevent from that smoker from pointing to be burned.

In a kind of preferred embodiment, described electric heating type cigarette, from that one end away from cigarette holder, comprises socket is connected successively cell section 1, changeover portion 2, bringing-up section 3, fillter section 4 and cigarette holder 5.Described bringing-up section 3 forms a plurality of destructive distillation chamber jointly by cartridge heater 31 and interior heating plate 32 axial perpendicular to cigarette and that keep at a certain distance away; A plurality of ventholes 36 that are connected with carbonizing gas outlet passageway are set on described interior heating plate; Described fillter section is connected with carbonizing gas outlet passageway.Described cell section is that cartridge heater and interior heating plate are powered by circuit, and tobacco product is heated.By control circuit, heating-up temperature is remained on below 500 ℃, realize quick low-temperature heat.

Described interior heating plate is fixed on cartridge heater, and is connected with cartridge heater, tobacco product is heated simultaneously.

The thickness of described interior heating plate is 0.5-1.5mm.

Between described cartridge heater 31 and fillter section 4, be provided with dry distiller dividing plate 37, on this dry distiller dividing plate 37, be provided with at least one outlet passageway 35.

Described cartridge heater 31 is configured to the whole form opening and closing, to change the tobacco product in each destructive distillation chamber.For example, described cartridge heater 31 is by along being axially divided into two semi-cylindrical shaped parts, and two semi-cylindrical shaped parts can be opened freely or close, and for example the two connects by draw-in groove or connects by rotating shaft, etc.

In preferred embodiments, circuit design in the electric heating type cigarette with a plurality of destructive distillation chamber described in the utility model is configured such that described cartridge heater 31 is continuously energized heating, and make described in several heating plates 32 from the heating one by one that starts to switch on successively of the interior heating plate away from cigarette holder.The heating temp of wherein said cartridge heater is controlled in being fuming below temperature of tobacco product, and the heating temp of described interior heating plate is controlled in being fuming more than temperature of tobacco product.Thus, cartridge heater mainly plays pre-heat effect, and interior heating plate plays the effect that heating is fuming.Conventionally, the be fuming concrete numerical value of temperature will depend on the type of used tobacco product.

The beneficial effects of the utility model are:

Smoking set in the utility model carries out preheating and a plurality of interior heating plate by cartridge heater and heats successively tobacco product is fuming, and heating surface (area) (HS enlarges markedly, and preheating is abundant, firing rate is fast and homogeneous heating, is fuming fast, can effectively improve the utilization rate of pipe tobacco.And avoided traditional electrical hot type cigarette tobacco overheated being burnt of skin causing when zone of heating heats tobacco to be from outside to inside set and the disadvantage that tobacco internal is not also fully heated around in cigarette.

The utility model is reasonable in design, simple in structure, easy to use.
