For a better understanding of the present application, the following description is made in connection with one embodiment:

fig. 1 shows a basic structure of an intelligent medium temperature heating non-combustion apparatus, the apparatus comprising:

a detachable suction nozzle 1;

a tubular insulating housing 14, wherein a pressure reducing valve 16 and a spring needle control button 17 are arranged on the housing 14;

The longitudinal heating circuit 36 and the heating pintle 11 adopt a constant temperature heating mode; the heating wall needle 15 and the transverse sectional heating circuit perform sectional heating under the control of the intelligent control circuit.

The cock 3 is provided with a molecular sieve as shown in fig. 2. The flue gas generated in the process of baking the cut tobacco by the heating cavity 10 is mainly solid, liquid and gas concurrent aerosol generated by pyrolysis, polymerization and condensation under the condition of oxygen deficiency through endothermic reaction, and particles are larger than air molecules, so that a one-way communicating vessel is formed by a molecular sieve filter screen and air outside the cavity, and the problem of flue gas diffusion after communication is synchronously solved.

The film heating plate 12 is a multi-layer structure (as shown in fig. 3), and is formed by overlapping polyimide films (PI films) and heating wires, wherein the PI film 33 is an outer wall on the side close to the inner wall of the equipment cavity, the PI film 31 is an inner cavity on the side close to a heating object (such as a cigarette), the PI film 31 is an inner cavity on the side close to the longitudinal heating wire 32, and the PI film 31 is an outer cavity on the side close to the transverse heating wire 34.

A, B, C in fig. 1 are schematically three lateral segments. The number of transverse segments required can be set by a person skilled in the art as desired.

The surface of the film heating plate 12 is provided with wall needle positioning holes for ensuring that the telescopic wall needles pass through the wall needle holes 35 and are fixed in the heating object (such as cigarettes) body. The longitudinal heating circuit 36 and the transverse sectional heating circuit are electrically connected with the intelligent temperature control device 30, after a heating body (such as a cigarette) enters the heating cavity 10, the intelligent temperature control device 30 preferentially starts the longitudinal heating circuit 36 to perform constant temperature heating, and starts the transverse sectional heating circuit according to pressure change and induction gravity change in the cavity, and the heating wall needle 15 is wrapped by a film body to be pricked into the heating wall needle to form regional three-dimensional heating, so that the front, middle and rear sections of the heating body (such as the cigarette) are effectively heated in a partition under the control of the intelligent temperature control device 30, and are quickly gasified in a short time to achieve the best taste. The three-stage lateral heating circuits 37, 38, 39 in fig. 4 are for illustration purposes only, and in practice the number of stages of the lateral heating circuit may be set according to the actual needs, and typically there are more stages.

Because polyimide film (PI film) has better heat conductance and high temperature resistance, the film heating plate 12 is manufactured by processing the heating wire array and the polyimide film (PI film), and the film heating plate 12 is closed along the horizontal direction to form a cavity structure for baking outside the cigarettes, and the problem of uneven heating of the film heating plate 12 is comprehensively solved.

The film heating plate 12 is provided with an array of holes for heating wall needles 15, so that the heating wall needles 15 can enter and exit the needle storage cavity 13.

The heating wall needle 15 is contracted in the needle storage cavity 13 at ordinary times, and is driven by the cock 3 to unscrew from the needle storage cavity 13 and pierce the cigarettes when in use, and forms a heating section with one group of heating plates and the peripheral needles in the corresponding film heating plates 12, so that the cigarettes in the section are baked. The heating wall needle 15 pierces the tobacco shred in the heating area effectively, increases the tobacco shred gap, improves the smoke permeability, improves the baking efficiency, and increases the comfort of sucking.

In the process of filling cigarettes, the heating shaft needle 11 pierces the cigarettes, the function of fixing the positions of the cigarettes and heating the base temperature is provided, and the continuous heat supply of the heating shaft needle 11 effectively reduces the condition that smoke is absorbed by cut tobacco heated at low temperature, so that the smoke is abundant and the smoke concentration is closer to the actual smoke concentration.

The tobacco shred is mainly divided into 4 processes in the combustion process, wherein the first process (100-120 ℃) mainly comprises vapor evaporation (moisture and crystallization water), the second process (120-230 ℃) comprises the steps of transferring compounds such as proteins and substances such as low molecular alcohols and esters to smoke, simultaneously starting aerobic pyrolysis of simple sugar, fibers and the like, the third process (about 230-360 ℃) comprises a similar combustion part (360-600 ℃) and a macromolecular pyrolysis process, and the fourth process mainly comprises the steps of pyrolysis of components such as amine-containing compounds, lignin, amide derivatives and the like and coke combustion. In the medium temperature heating non-combustion process, the fourth process is a reject stage, but it is necessary to mimic the smoldering portion of smoke. The thermodynamic property of tobacco leaves belongs to ash bodies in the heating process, and the nonlinear heating capacity can be achieved by using the heat radiation heating effect, so that when the heating wall needle 15, the heating shaft needle 11 and the thin film heating sheet 12 are heated, the radiation heating and the contact heating are synchronously implemented when the isolated logic heating area is heated, the optimal baking temperature of the baking area can be quickly reached to about 300 ℃ within 0.3 seconds, the smoldering process is completely simulated, and the taste of the smoke is optimal.

To ensure that the baking process is consistent with the natural process, i.e. the single port smoke intake should be at least 35ml, the array of film heater plates should provide at least 3-5 ml of direct heating zone during baking (simulation process three) to provide sufficient smoke content, while providing 2-fold length of preheating zone (simulation of process one, process two, respectively during combustion) to provide auxiliary sufficient individual species concentrations of smoke mixture. A plurality of transverse heating sections may be provided in the heating chamber 10, each section forming a heating zone (a solid heating zone is formed by a partial, partial heating wall pin and a heating axis pin of the thin film heater plate 12). Three adjacent heating zones simulate a first process, a second process and a third process, respectively.

The structure of the heating wall needle 15 extending and retracting from the needle storage chamber 13 will be described in detail below.

As shown in fig. 5, the wall needle 15 is placed in the needle storage cavity 13 through the wall needle frame 41, the wall needle frame 41 is connected with the cock 3, and when the cock 3 rotates, the wall needle frame 41 is driven to rotate, so that the wall needle 15 is pushed to enter and exit the needle hole 35, and the actions of penetrating and separating cigarettes are completed.

As shown in fig. 6, the wall needle cantilever beam 43 rotates about a cantilever beam axis 45, and the cantilever beam rail 46 and the cantilever beam rail 47 provide control of the span of movement of the cantilever beam.

As shown in fig. 7, the pinhole portion of the film heating sheet 12 is designed as a recessed wall needle guide groove 42 for track guiding when the wall needle 15 enters and exits the pinhole 35, and the running track of the wall needle 15 is fixed.

The structure of the heating non-combustible apparatus associated with the adaptation of the morphology of the cigarettes is described in detail below. Including radial and axial adaptations.

Radial adaptation, also called diameter adaptation, is the radial adjustment of the tubular cavity formed by the thin film heater plate 12, preferably the radial adjustment interval (radius) may be (0-1.2 mm), the diameter variation principle being shown in fig. 8.

The reducing adjusting rod 52 is connected with the inner wall cavity 51 of the baking device and the reducing pressing sheet 54, the reducing adjusting valve 53 is embedded, and the reducing adjusting valve 53 is embedded into the reducing adjusting rod 52 through a chute. When the needle is rotated along the needle potential, the reducing regulating valve 53 extrudes the reducing regulating rod 52 to enlarge the distance d, pulls the reducing pressing sheet 54 to move towards the wall to enlarge the inner cavity diameter, and stops when reaching the maximum cavity diameter control point; otherwise, d is reduced, and the variable-diameter pressing sheet 54 is pushed to move to the center of the circle.

Wall-wise reset of the thin film heater chip 12: the PI film has better flexibility and mechanical property, wherein the electric heating wire is a metal wire, and the metal wire has excellent elastic resetting capability, so that the film heating plate 12 and the variable-diameter pressing plate 54 are always tightly pressed by applying the elastic resetting capability of the PI film.

The diameter-changing adaptation may be implemented in other similar ways than the example shown in fig. 8. For example, as shown in fig. 9, if the diameter-changing adjusting lever 52 is replaced with an elastic metal piece 55 (diameter-changing adjusting piece), the diameter-changing adjusting valve 53 may be replaced with a hinge 56 to achieve the same control effect.

The axial fit is also called length fit, as shown in fig. 10, the electromagnet 4 generates magnetic force with the same polarity as the permanent magnet 21 on the plug 3, and acts with the permanent magnet 21 on the plug 3 to push the plug 3 forward until the plug 3 is blocked by one end of the cigarette, so as to close the front end of the cigarette.

The key effect of the fitting of the cigarettes is achieved cooperatively by the internal series of mechanical structures of the tap 3, the longitudinal cross-sectional view of which is shown in fig. 11.

The following describes the principle of operation of the mechanical structure during the fitting of cigarettes, with reference to fig. 12 in the transmission disengaged state and fig. 13 in the transmission engaged state:

1) Cigarette adaptation straight double lock 63: the direct lock 63 defaults to a drive disengaged state in which rotation of the tap 3 only controls the wall needle to unscrew.

2) When the straight double-locking pulling piece (namely the cigarette adapting switch) is positioned on, the straight double-locking pushing pressing piece 68 drives the transmission gear sleeve 69 to be tightly combined with the cone of the transmission gear 60 to form a linked rigid body structure, and drives the reducing regulating valve 53 to rotate.

3) The surface of the pressing piece 68 and the position of the straight-resetting locking radial arm 64 are provided with clamping grooves (radial arm clamping grooves 67) for fixing the position of the pressing piece 68, and when the cigarette is properly matched, the straight-resetting locking radial arm 64 is engaged with the radial arm clamping grooves 67 to fix the pressing piece 68 not to rotate any more until the straight-resetting lock 63 is pulled back to the disengaged state.

4) 2 seconds after the clamping grooves of the straight-resetting locking rotating arm 64 and the pressing piece 68 are closed, the electromagnet 4 starts to work, and magnetic force is generated to push out the pintle 11 for axial cigarette adaptation.

Another embodiment of the application is shown in fig. 14, where the tubular structure of the heating non-combustion apparatus can be functionally and morphologically divided into two parts, a baking tube 7 and a swirl tube 8, as shown in fig. 14.

The main function of the baking tube 7 is to complete cigarette baking and cigarette adaptation, and the main function of the rotary control tube 8 is used for placing power supply (battery pack 5), various circuits, electromagnet 4 and other expansion function devices, and is realized by rotary control baking and cigarette adaptation effects. The electrical devices in the rotary control pipe 8 are spatially isolated and insulated by an isolating ring 9. The main structures in the baking tube 7 are the wall needle frame 41, the film heating plate 12 and the cock 3, and the working process is as described above. The baking tube 7 is connected with the rotary control tube 8 through a nut mechanism. When the device is not in use, the components are in the initial position. The cigarettes are inserted into the baking tube 7, leaving the filter tip outside the cavity. If the cigarettes need to be matched, the cigarette matching direct double lock 63 on the rotary control tube 8 is shifted to the on position, the rotary control tube 8 is rotated, and the radial cigarette matching process is started. The spring needle control button 17 is pressed, the axial adaptation process is started and heating is started. After the heating is finished, the direct-resetting lock 63 is opened, the rotary control pipe 8 is reversely rotated, the heating wall needle 15 is reset, the transmission gear 60 is separated, and the baking device enters a standby state. The baking process is controlled by an intelligent algorithm of the control circuit.
