Technical Field
The utility model belongs to aerosol generates goods field.
Background
Aerosol generation by electronic devices heating aerosol generating materials rather than combustion has evolved in recent years as an alternative to the mainstream of conventional lit cigarettes. The aerosol generating material can be plant leaf solid material with corresponding substance components, and can be further added with fragrance material to generate aerosol with unique fragrance under heating condition for user to smoke.
However, current aerosol-generating articles of the heated non-combustible type suffer from the following problems:
1. the air flow path in the current non-combustible heated products is almost one-way, and in the process of smoking, air enters from the end of a cigarette and passes through the heated tobacco material, and aerogel generated by cracking the heated material is taken out and then enters the mouth of a smoker. Cold air is mixed into the material heating area in the air flowing process triggered by the pumping action, the temperature of the heated material is liable to be rapidly reduced, the temperature fluctuation of the subsequent material heating area is large, the cracking reaction types and degrees of the materials generated at different temperatures are different, the released aroma substances are also different, and the problem of inconsistent quality among the front pumping port, the middle pumping port, the rear pumping port, the front pumping port and the rear pumping port is brought to a sucker.
2. The temperature of the material heating area is reduced to different degrees due to different suction habits of different smokers and the air flow formed by suction, which brings great uncertainty to the consistency of the temperature curve of the heater, and is a common problem in heating non-combustible products.
3. The air current that the cigarette that does not burn at the heating that has the structural design that punches at present played and changes the resistance of inhaling in the suction in-process formation can only play, reduces the effect of gas temperature, and the low temperature air can't be in the material zone of heating, keep still effectively taking out the aerogel when the zone temperature of heating.

Wherein upstream and downstream are defined by the flow direction of the aerosol. Typically, the segment of aerosol generating material is upstream and the filter segment is downstream.
Wherein the insulating firmware, when present, functions to prevent downstream movement of the segment of aerosol generating material while providing a delivery channel for aerosol. When a heating element is inserted inside the segment of aerosol-generating material, the aerosol-generating material tends to move downstream due to the urging action of the insertion force, which may result in insufficient thermal contact between the heating element and the segment of aerosol-generating material. The spacer may resist this tendency to move downstream by virtue of adhesion and/or frictional resistance between its periphery and the inner wall of the outer tube. When the aerosol-generating material is in the form of particles, the barrier member may also act to confine the particles and prevent them from scattering downstream. Of course, when the length of aerosol-generating material is a unitary piece, such as a unitary round rod, and a space for insertion of a heating element is reserved or by heating the periphery of the length 3 of aerosol-generating material, the spacer may not be used because there is no downstream pushing force.

Therefore, the sealing film 2 is preferably an airtight sealing film. Of course, if the aerosol generating device used with the aerosol generating article is capable of providing a sealing means, the end of the non-combustible aerosol generating article may be free of the sealing film 2 and the outer wall may be non-airtight.
Preferably, the edge of the air guide fixture 5 has at least one, preferably a plurality of axially extending ventilation slots which form the edge air passage 52 with the inner wall of the outer tube 1. More preferably, the plurality of axially extending venting slots are evenly distributed along the outer periphery of the air guide fixture. The cross section shapes of the central air passage and the edge air passage are not limited.
Wherein the length 3 of aerosol-generating material contains a filamentary, sheet, particulate or bulk aerosol-generating material. Preferably, the aerosol-generating material may be, for example, tobacco, but of course other herbs are also possible.
Preferably, a filter segment 6 is further arranged at the downstream of the air guide firmware 5.
There is no limitation on the material of each of the insulating fixing member 4 and the air guide fixing member 5 as long as they can withstand high temperature, for example, not soften and deform at 250 ℃ or more and not release harmful substances. Preferably, the isolation fixing member 4 and the air guide fixing member 5 may be independently made of a silicone material or a ceramic material.
Preferably, the air inlet 11 is a circular cut, an arc cut or a scattered cut penetrating the tube wall of the outer tube 1.
Preferably, the outer tube 1 is formed from a wound sheet of paper or is a preformed paper tube.
The utility model discloses a heating incombustible type aerosol generates goods, the heating direction in aerosol generates the utensil can be central heating (heating element inserts aerosol and generates material internal heating), circumferential heating (the heater surrounds the outer tube heats from inside to outside), and the heating methods can be resistance-type heating also can be electromagnetic type heating. Therefore, the utility model discloses a heating incombustible type aerosol generates goods application scope is very wide, uses with various smoking set homoenergetic well in a complete set.
When the aerosol-generating article of the present invention is heated with an aerosol-generating appliance, the segment of aerosol-generating material is heated to release the aerosol. When a user draws on the near labial end of the outer tube, ambient air enters the peripheral air passage 52 from the air inlet 11 and moves along the peripheral air passage 52 towards the upstream end of the aerosol-generating article, encounters the aerosol at the upstream end face of the air guide fixture 5 and carries it with it to turn into the central air passage, thereby performing the extraction and entrainment of the aerosol, which then flows together downstream along the central air passage into the user's mouth.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. ambient air entering the tobacco rod does not flow through the length of aerosol-generating material but is drawn downstream thereof by means of the air flow diverter and carries aerosol released by heating of the aerosol-generating material into the tobacco rod downstream. Because the ambient air does not flow through the aerosol-generating material segment, the problems of large temperature fluctuation and inconsistent fragrance release caused by air entering the segment can be avoided. Therefore, use the utility model discloses an aerosol generates goods, can effectively keep the invariant of material zone of heating temperature, suction smog is great, and the continuation is good, suction sensory quality preferred, and the uniformity is better all around, gives the better suction of suction person and experiences, simultaneously also greatly reduced the uncontrollable factor that heater temperature set up.
2. Because no or little ambient air enters the segment of aerosol-generating material, resulting in the segment being subjected to oxygen-deficient or even oxygen-isolated conditions in which the ignition point of the material is increased, scorching or burning of the aerosol-generating material due to excessive temperatures can be effectively avoided, and scorched or burnt flavors can be avoided. In addition, higher heating temperatures (e.g., 350 ℃ higher than the conventional heating temperature, or even up to 400 ℃ or higher) can be used to more fully release the aerosol, especially to release the flavor molecules that are released only at higher temperatures to provide a richer flavor experience.
