Description
Technical Field
The invention relates to the technical field of heating non-combustible tobacco products in the tobacco industry, in particular to an aerosol generating product with sufficient smoke.
Background
The existing electronic cigarette without burning needs to use a special smoking set when heating, and the smoking set is provided with a heating body inserted into a cigarette for heating; usually, the heating length in commercially available smoking articles is around 2cm, which makes it necessary to match the length of the functional segment of the tobacco rod structure for aerosol generation, otherwise the excess length cannot be heated, which is obviously undesirable for users who require a sufficient smoking amount.
Meanwhile, when a granular aerosol generating substrate is adopted, the granular aerosol generating substrate is easy to drop into the heater to damage the heater in the process of inserting the heating body. On the other hand, since the particles roll easily, it is first necessary to pack a barrier in the paper tube to prevent it from rolling before packing the particulate aerosol-generating substrate. The adoption of the form of the sealing sheet obviously increases the production cost of the whole cigarette, and the adoption of the mode of the barrier piece not only increases the production cost, but also increases the integral suction resistance of the cigarette, so that a consumer cannot suck sufficient heated smoke.
For example, CN108433197A or CN109043654A of the prior art discloses a non-combustible heated cigarette and its components, in which a first forming paper is wrapped around a tobacco segment to form a cigarette, a second forming paper is wrapped around a first filter segment and a second filter segment to form a composite filter rod, and tipping paper is used to roll the cigarette and the composite filter rod together. But the tobacco is wrapped only by tobacco shreds or cut stems, the suction resistance is large, and the tobacco sections are easy to deform or damage. For example, CN112244351A, CN113662239A, CN214179111U, CN112120281A, etc. are known in the art. How to solve the problem of falling and rolling while using the granular smoking material without increasing the cost and the resistance to draw and simultaneously can provide sufficient smoke volume is a difficult problem in the field of heating non-combustible tobacco.

When the fragrance-carrying particles are filled, they may reciprocate between the first hollow section and the second hollow section through the smoke passage, which does not affect their effectiveness. According to the invention, the circular truncated cone-shaped/frustum-shaped cooling element is arranged, so that smoke generated by aerosol generating substrates is further cooled when passing through the cooling element, and the cooling element is equivalent to a Venturi tube at the moment, so that the cooling effect is particularly obvious, and the user is ensured not to feel that the mouth is scalded when sucking.
(4) According to the invention, the heating extension sheet is arranged into an M shape, so that on one hand, the coverage area of the heating extension sheet is increased, thereby improving the heat transfer efficiency of the heating extension sheet, and on the other hand, the joint is convenient to arrange, and the heating body is prevented from being blocked by the heating extension sheet when being inserted into an aerosol generating product, so that the heating body is prevented from being bent; the leakage of aerosol generating substrates caused by that the heating body pushes the heating extension sheet to puncture the wrapping bag can also be avoided.
The above-described embodiments are illustrative of the present invention and not restrictive, it being understood that various changes, modifications, substitutions and alterations can be made herein without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
