Description
Technical field
The utility model relates to a kind of non-burning cigarette of heating, and in particular to a kind of heating for electronics heating is non-burning
Cigarette.
Background technique
As international tobacco control form is more and more severeer, numerous smokers urgent need is a kind of to be not only able to satisfy smoking hobby but also low
Harmful cigarette, heating non-combustion-cigarette straw-made articles are born therewith.
At present heating non-combustion-cigarette straw-made articles be widely used electric heating form enable nicotine in tobacco at cigarette substance
Release, lower at smoke temperature degree compared with traditional tobacco due to the process that do not burn, can achieve, which reduces harmful substance, releases
The purpose put.But the heating non-combustion-cigarette straw-made articles of electric heating type generally has the heating process of 20 ~ 40s before suction, this
Tobacco segment is heated to 200 ~ 300 degrees Celsius in the process, and mouth stick and the excessively high phenomenon of flue-gas temperature are had in suction.
Utility model content
The utility model aim is to provide one kind for the electrically heated non-burning cigarette of heating, when reducing suction to reach
Flue gas and filter stick temperature, while reducing the purpose of tar-concentration in flue gas.
The technical solution of the utility model is to provide a kind of non-burning cigarette of heating, including cigarette holder part and tobacco section,
Cigarette holder part includes filter and cooling element, and cooling element is between tobacco section and filter；
Cooling element be hollow tubular structure, along the flow direction of flue gas, cooling element be divided into upper section, middle section,
Lower section, upper section is close to tobacco section, and lower section is close to filter；Upper section is large cylinder, and lower section is small cylinder, and middle section is connection great circle
The rotary table of cylinder and small cylinder；Upper section, middle section, lower section, which are sequentially connected in series connection, to be made to form exhaust gases passes inside cooling element, middle section
Internal diameter at smoke inlet is identical as the internal diameter of upper section smoke outlet, and internal diameter and the lower section flue gas of the smoke outlet in middle section enter
Internal diameter at mouthful is identical；
Filter, cooling element and the external of cigarette holder part bond and are enclosed with paper；Cooling element and filter it
Between paper be equipped with air hole.The paper that mouth stick (i.e. cigarette holder part) different piece bonds together in tobacco business be referred to as at
Type paper, the paper that mouth stick and cigarette (i.e. tobacco section) are bonded together become tipping paper or cork paper.
Preferably, paper includes forming paper and tipping paper；Filter and cooling element are by forming paper composite molding, mouthpiece portion
Divide and tobacco section is by tipping paper composite molding；It is equipped in forming paper and tipping paper between cooling element and filter ventilative
Hole.Or only by tipping paper by entire cigarette bonding forming.

Or polypropylene.
Preferably, the length of cooling element is 20 ~ 35mm.
Preferably, the tobacco section length is 10 ~ 50mm；Filter length is 5 ~ 10mm.
Preferably, tobacco section is by one of pipe tobacco, stem, extruding pipe tobacco, extruding stem, reconstituted tobacco or a variety of
It is mixed.
Filter, cooling element and tobacco section can be by tipping papers by above-mentioned three parts composite molding；Can also by
Type paper and tipping paper composite molding twice.When by forming paper and tipping paper compound tense twice, cooling element and filter are by forming
Paper composite molding forms cigarette holder part, and cigarette holder part and tobacco section are by tipping paper composite molding；In cooling element and filter
Between forming paper and tipping paper be equipped with air hole.Since the air hole in forming paper and tipping paper is preparatory punches then again
Composite molding, therefore need to position when punching, so that forming paper can be overlapped with the position of the air hole on tipping paper.
It is uniformly distributed circumferentially four air holes on the tube wall (forming paper) of cigarette holder part, air hole can be (but unlimited
It is fixed) it is round, ellipse, rectangle.
The material of filter can (but not limiting) be acetate fiber, tacryl, sucrose fiber, wood pulp cellulose, tobacco
One of fiber, bombax cotton, ceramic fibre, ramee etc. or a variety of mixing.The diameter and cooling element of filter
Outer diameter it is identical.
Forming paper is high-air-permeability forming paper, and air permeability is greater than or equal to 3000CU.There is an at least row pre- on tipping paper
Through-hole (practical is also air hole, for convenient for differentiation, referred to as reserved through hole) is stayed, the position of the reserved through hole is non-in the heating
It is uniformly distributed circumferentially on burning cigarette, and Chong Die with the air hole in forming paper in the axial direction.Non-burning cigarette is heated to take out
When suction, there is a small part air to flow by the reserved through hole on tipping paper, the air hole in forming paper and heat non-burning cigarette
Inside converge with main flume, achieve the purpose that reduce tar-concentration in flue gas, while flue-gas temperature can be further decreased.
The utility model has the beneficial effects that passing through the flow velocity and pressure, benefit that change flue gas in mouth stick using cooling element
Increase the heat exchange area two ways of mouth stick and flue gas with fin to reduce flue-gas temperature；Cigarette holder part using high porosity plug wrap paper with
Air hole is directly entered portion of air inside mouth stick and mixes with flue gas, reduce the tar-concentration in flue gas, at the same also into
One step reduces flue-gas temperature.
