Continuing to refer to figure 4 in conjunction with figure 1, figure 4 shows a schematic cross-sectional view of a smoking article 200 in one direction. Smoking article 200 is generally elongate and has opposing mouthpiece section 210 and tobacco section 220, and a cooling section 230 disposed between mouthpiece section 210 and tobacco section 220, with mouthpiece section 210 being filled with a filter (not shown) and a user drawing directly through mouthpiece section 210. The cut tobacco section 220 is filled with active volatile substances such as tobacco and the like, and can be volatilized under the heating condition to generate smoke; the temperature reduction section 230 is provided with an air inlet 2310 for external air to enter the smoking article 200, when a user sucks on the mouthpiece section 210, the external air can enter the smoking article 200 through the air inlet 2310 and flows to the mouthpiece section 210 along with the aerosol generated by the tobacco shred section 220 for the user to suck, and due to the external air entering the temperature reduction section 230, the external air and the high-temperature aerosol can be mixed to effectively reduce the temperature of the high-temperature aerosol, so that the temperature of the aerosol sucked by the user is appropriate. When the smoking article 200 is housed in the aerosol-generating device 100, the mouth section 210 is exposed to the exterior of the aerosol-generating device 100, and the tobacco segment 220 is housed in the aerosol-generating device 100 such that the tobacco is heated by the aerosol-generating device 100.

The aerosol-generating device 100 comprises a housing 10, a first flexible clip 20, a first end cap 30, a second flexible clip 40, a heating tube 50, a second end cap 60, a seal 70, a heating element 80 and a conductive electrode 90. The housing 10 is a hollow cylindrical body with two open ends, and the first end cap 30 and the second end cap 60 are respectively installed inside the housing 10 from the two open ends of the housing 10; the heating tube 50 is supported on the second end cap 60, the second flexible clamping member 40 is supported on the heating tube 50, the first end cap 30 is supported on the second flexible clamping member 40, the first flexible clamping member 20 is disposed on the first end cap 30, the sealing member 70 abuts between the heating tube 50 and the second end cap 60, the heating element 80 is attached to the outer surface of the heating tube 50, and the conductive electrode 90 is electrically connected with the heating element 80.

With continued reference to fig. 5 and 6, fig. 5 and 6 respectively show perspective views of the first end cap 30 in two directions. The first end cap 30 includes an end surface 31, a support surface 32, and a hollow tubular body 33 extending axially from the support surface 32 toward the heat pipe 50. The first end cap 30 further includes a connecting end surface 31 and a supporting surface 32, and a first boss structure 311 extending radially toward the hollow tubular body 33, an extending portion 312 extending axially from the end surface 31 toward the heating pipe 50, a second boss structure 313 formed on an inner wall of the extending portion 312, and the first boss structure 311 and the second boss structure 313 as a first fastening portion are fastened to the first flexible clamping member 20 and the second flexible clamping member 40, respectively, so that the first flexible clamping member 20 and the second flexible clamping member 40 are positioned in the circumferential direction, and the first flexible clamping member 20 and the second flexible clamping member 40 are prevented from rotating.

Referring to fig. 3, the first flexible clamping member 20 and the second flexible clamping member 40 are both made of elastic soft rubber material, such as silicon rubber or rubber. The first flexible clamping member 20 has opposite first and second end surfaces 21 and 22 and a side wall 23 extending between the first and second end surfaces 21 and 22, and the second flexible clamping member 40 also has opposite first and second end surfaces 41 and 42 and a side wall 43 extending between the first and second end surfaces 41 and 42. The side wall 23 of the first flexible clamping member 20 and the side wall 43 of the second flexible clamping member are formed with a locking groove 231 and a locking groove 431 extending axially, and the locking groove 231 and the locking groove 431 are used as a second locking part to be mutually locked with the first locking part of the first end cover 30. Specifically, the first boss structure 311 of the first end cap 30 is clamped in the clamping groove 231, the second boss structure 313 is clamped in the clamping groove 431, and the first flexible clamping member 20 and the second flexible clamping member 40 are both made of elastic soft rubber materials, so that the first boss structure 311 and the second boss structure 313 can be clamped by the elastic restoring force when the first flexible clamping member 20 and the second flexible clamping member 40 are clamped with the first end cap 30, and the first flexible clamping member 20 and the second flexible clamping member 40 are prevented from easily falling off from the first end cap 30.

In addition, in order to facilitate the engagement of the first and second flexible holders 20 and 40 with the first end cap 30 during the installation, the first boss structure 311 is formed with a first guide surface 3111, the second boss structure 313 is formed with a second guide surface 3131, and the first guide surface 3111 and the second guide surface 3131 are used for guiding the engagement of the first and second flexible holders 20 and 40 with the first end cap 30. In addition, the inner wall of the hollow tubular body 33 is further formed with a guiding surface 331, and the guiding surface 33 is used for providing guidance when the aerosol product 200 protrudes into the hollow tubular body 33 of the first end cap 30, so that the aerosol product 200 can smoothly protrude into the first end cap 30 and pass through from the hollow tubular body 33 of the first end cap 30.

With reference to fig. 3, the first flexible clamping member 20 has a first extending portion 24 extending radially from the first end surface 21, the first extending portion 24 is not closed to form a first through hole 241, the second flexible clamping member 40 has a second extending portion 44 extending radially from the second end surface 42, and the second extending portion 44 is not closed to form a second through hole 441. The heating tube 50 is configured as a hollow cylindrical body with two open ends, and the first end surface 41 and the second end surface 42 of the second flexible clamping member 40 are respectively pressed by the first end cover 30 and the heating tube 50, that is, the second flexible clamping member 40 is disposed between the first end cover 30 and the heating tube 50, so that the first through hole 241 of the first flexible clamping member 20, the hollow tubular body 33 of the first end cover 30, the second through hole 441 of the second flexible clamping member 40 and the hollow region of the heating tube 50 are communicated to form the heating chamber 11, so that the smoking article 200 can be inserted into and accommodated in the heating assembly 241 through the heating chamber 11, and the first through hole is an open end of the heating chamber 11 for providing an inlet of the smoking article 200 into the heating chamber 11. It will be appreciated that the first extension 24 may extend from the sidewall 23 of the first flexible clamping member 20, and similarly, the second extension 44 may extend from the sidewall 43 of the second flexible clamping member 40.

It should be noted that the thicknesses of the first extension portion 24 and the second extension portion 44 are gradually reduced along the radial direction, that is, the thickness of the initial extension portion of the first extension portion 24 is greater than the thickness of the hole wall of the first through hole 241, and the thickness of the initial extension portion of the second extension portion 44 is greater than the thickness of the hole wall of the second through hole 441. The greater thickness of the initial extension portion can ensure better connection strength between the first extension portion 24 and the second extension portion 44, and the gradually decreasing thickness in the radial direction can reduce the thickness of the first through hole 241 and the thickness of the wall of the second through hole 441, so that the smoking article 200 can more smoothly pass through the first through hole 241 and the second through hole 441, and the smaller thicknesses of the first through hole 241 and the second through hole 441 can reduce the obstruction to the smoking article 200. The radial thickness gradually decreases as indicated by the arrows in fig. 7R 1.

When the smoking article 200 is received in the aerosol-generating device 100 by the heating chamber 11, the smoking article 200 first passes through the first through hole 241 into the hollow tubular body 33 of the first end cap 30, and then from the hollow tubular body 33 of the first end cap 30 through the second through hole 441 into the heating tube 50. It should be noted that the apertures of the first through hole 241 and the second through hole 441 are slightly smaller than the outer diameter of the smoking article 200, and the outer diameter of the smoking article 200 is smaller than the tube diameters of the hollow tubular body 33 and the heating tube 50 of the first end cap 30, therefore, when the smoking article 200 passes through the first through hole 241 and the second through hole 441, the surface of the smoking article 200 circumferentially presses the hole walls of the first through hole 241 and the second through hole 441, so that the first flexible clamping member 20 and the second flexible clamping member 40 deform, and because the first flexible clamping member 20 and the second flexible clamping member 40 have elasticity, under the action of elastic restoring force, the hole walls of the first through hole 241 and the second through hole 441 generate a reverse extrusion force on the surface of the smoking article 200, and under the action of the reverse extrusion force, the hole walls of the first through hole 241 and the second through hole 441 circumferentially tightly clamp the smoking article 200, so that the smoking article 200 is not easily pulled out when being accommodated in the aerosol generating device 100, and the lip of the user is effectively prevented from taking the smoking article 200 out.

In addition, since the smoking article 200 is tightly clamped in the circumferential direction by the hole walls of the first through hole 241 and the second through hole 441, after entering the heating chamber 11 through the open end of the heating chamber 11, the external air cannot flow to the bottom of the heating chamber 11 through the gap between the hole wall of the first through hole 241 and the surface of the smoking article 200 and the gap between the hole wall of the second through hole 441 and the surface of the smoking article 200, so that the external air cannot enter the cut tobacco segment 220 of the smoking article 200 from the top of the aerosol-generating device 100. It is to be noted that the thickness of the hole walls of the first through hole 241 and the second through hole 441 is preferably set in the range of 0.1 to 1mm, and the hole wall thickness in this range is advantageous for sealing. See the thickness indicated by d1 in fig. 7.

With continued reference to fig. 8, fig. 8 shows a perspective view of the second end cap 60 in one orientation. The second end cap 60 comprises a bottom wall 61, an outer wall 62 extending axially from the bottom wall 61 towards the heating tube 50, and a hollow tubular body 63 extending from the bottom wall 61 towards the heating tube 50, wherein the hollow tubular body 63 extends into the hollow area of the heating tube 50 from the lower end of the heating tube 50, when the smoking article 200 is accommodated in the heating chamber 11, the end surface of the bottom of the smoking article 200, that is, the end surface of the tobacco rod section 220, abuts against the end surface of the hollow tubular body 63, and thus the smoking article 200 can be limited to a proper insertion depth, so that a proper height is left to be exposed outside the aerosol generating device 100 for a user to suck.

An annular gap 64 is formed between the outer wall 62 and the hollow tubular body 63, and the lower end of the heating tube 50 is located in the annular gap 64. The sealing member 70 is filled in the annular gap 64 around the hollow tubular body 63, the lower end of the heating tube 50 is pressed on the surface of the sealing member 70, and the sealing member 70 may be made of a flexible soft rubber material, such as silica gel or rubber, so that under the pressing force of the heating tube 50, the sealing member 70 may seal the assembly gap between the heating tube 50 and the second end cap 60, and prevent external air from entering into the heating tube 50 through the gap and further entering into the tobacco shred section 220 of the smoking article 200.

The outer wall cladding of heating pipe 50 has heating element 80, heating element 80 can be net heating element, net heating element can be that the heater is woven and is formed, also can be through trompil formation on the heating sheet, the heat that heating element 80 produced can transmit heating pipe 50, and then transmit tobacco products 200 by heating pipe 50, the material such as tobacco of tobacco products 200 intussuseption can be under the high temperature condition after the thermal volatilization production smog, also produce aerosol, the user can inhale aerosol through the suction nozzle of tobacco products 200.

Further to providing electrical power to the heating element 80, the aerosol-generating device 100 further comprises an electrically conductive electrode 90 electrically connected to the heating element 80, the electrically conductive electrode 90 filling the annular gap 64 around the hollow tubular body 63 of the second end cap 60 and being electrically connected to the heating element 80. The bottom wall 61 of the second end cap 60 is provided with an electrode hole 611, and the conductive electrode 90 extends out of the aerosol generating device 100 through the electrode hole 611 to be electrically connected with an external power supply mechanism, so that the external power supply mechanism supplies power to the aerosol generating device 100 through the conductive electrode 90.

It should be noted that the heating element 80 is coated on the outer wall of the heating tube 50, and then transfers heat to the aerosol product 200 in the heating chamber 11 through the outer wall of the heating tube 50, which belongs to a circumferential heating mode, that is, the heating tube 50 transfers heat to the aerosol product 200 from the circumferential direction. In other embodiments of the present invention, a central heating manner may also be adopted, for example, the heating element 80 may be disposed in the heating tube 50, the heating element 50 may be configured in a slender heating pin manner, and the heating pin may be in the form of a ceramic heating rod or an electromagnetic heating pin. The ceramic heating rod can be internally provided with a resistance heating material, an electromagnetic heating needle is adopted, an induction coil needs to be arranged on the outer wall of the heating pipe 50, alternating current is conducted to the induction coil, and the electromagnetic heating needle is usually made of a conductive metal material, so that eddy current can be generated on the electromagnetic heating needle under the action of electromagnetic induction, and the electromagnetic heating needle generates heat. When the aerosol product 200 is housed in the heating chamber 11, the heat generating pins are directly inserted into the aerosol product 200, and heat is radiated from the heat generating pins to the periphery, thereby forming a central heating system.

According to the above description, under the sealing action of the first flexible clamping member 20 and the second flexible clamping member 40, the external air cannot flow to the bottom of the heating chamber 11 through the open end of the heating chamber 11, and the external air can only enter the smoking article 200 through the air inlet 2310 of the smoking article 200, so that the air flow of the external air to the smoking article 200 is reduced, the cut tobacco section 220 of the smoking article 200 can be in a dilute oxygen environment, and the heating element 80 performs dilute oxygen heating on active substances such as tobacco in the cut tobacco section 220, at this time, even if the power of the heating element 80 is increased, the heat productivity of the heating element 80 is increased, the tobacco in the cut tobacco section 220 is not combusted, so that the release of tobacco aroma components can be increased, and the smoking taste is effectively improved. Further, in order to achieve a better heating effect of the diluted oxygen, the outer surface of the bottom wall 61 may be sealed by gluing, so as to completely block the gap of the bottom wall 61, thereby preventing the external air from entering the heating chamber 11 through the bottom wall 61, and of course, the blocked gap also includes the electrode hole 611, that is, the bottom of the heating chamber 11 is sealed, and the external air cannot enter the heating chamber 11 through the bottom of the heating chamber 11.

It should be noted that, in other embodiments of the present invention, only one flexible clamping member may be provided, although the effect of heating the diluted oxygen may be partially achieved, the sealing effect is not good enough. Because the pore wall thickness of through-hole is usually than thinner on the flexible holder, during the user's suction, atmospheric pressure promotes the pore wall of through-hole more easily and takes place the displacement in the axial to make the not inseparable centre gripping tobacco products 200 of pore wall of through-hole, then can produce tiny clearance between the pore wall of through-hole and the surface of tobacco products 200, outside air can enter into to the tobacco shred section 220 of tobacco products 200 through this tiny clearance, thereby influences sealing performance. Certainly, if the hole wall of the through hole is thicker, the displacement of the hole wall of the through hole under the action of air pressure impact can be effectively prevented, but the outer surface of the smoking article 200 is generally made of a softer paper material, so that when the smoking article 200 passes through the through hole of the flexible clamping piece, the paper material on the outer surface of the smoking article 200 is easily extruded by the thicker hole wall thickness, the paper material is easily indented, and external air can flow into the cut tobacco section 220 of the smoking article 200 through the indentation, so that the sealing performance is affected.

Through the first flexible clamping piece 20 and the second flexible clamping piece 40 in this embodiment, since the hole wall of the first through hole 241 of the first flexible clamping piece 20 and the hole wall of the second through hole 441 of the second flexible clamping piece 40 simultaneously clamp the smoking article 200, it is difficult for gas to impact the hole wall of the first through hole 241 and the hole wall of the second through hole 441 simultaneously, so that the hole wall of the first through hole 241 and the hole wall of the second through hole 441 simultaneously displace, and the smoking article 200 is respectively clamped by using the first flexible clamping piece 20 and the second flexible clamping piece 40, the hole wall of each flexible clamping piece through hole can be thinner, and when the smoking article 200 passes through, the indentation is not easily generated on the outer surface of the smoking article 200, so that the sealing performance can be effectively improved, and external air is prevented from entering the cut tobacco section 220 of the smoking article 200.

It is worth noting that in other embodiments of the present invention, three, four or more flexible retaining members may be used to retain the smoking article 200, it being understood that the more flexible retaining members are used, the better the sealing performance.

With continuing reference to fig. 9 and 10, fig. 9 and 10 respectively show a perspective view and a cross-sectional view of another embodiment of the flexible clamping member 20a in one direction. The first through hole 241 of the first flexible clamping member 20 and the second through hole 441 of the second flexible clamping member 40 may also be disposed on the same flexible clamping member 20a, the flexible clamping member 20a has a first end surface 21a and a second end surface 22a opposite to each other, the first end surface 21a circumferentially extends a first extending portion 211a along the radial direction, the first extending portion 211a is not closed to form a first through hole, the second end surface 22a circumferentially extends a second extending portion 221a along the radial direction, the second extending portion 221a is not closed to form a second through hole, the first through hole and the second through hole are communicated to form a channel 23a for the aerosol product 200 to penetrate through, when the smoking product 200 penetrates through the first through hole and the second through hole, the first through hole and the second through hole can clamp the smoking product 200, and the sealing effect of the above embodiment can also be achieved. It is easy to understand that the greater the number of through holes formed in the flexible clamping member 20a, the better the sealing effect; or a plurality of such flexible clamping members 20a, a better sealing effect can be achieved. In addition, the flexible clamping member 20a may also be provided with a clamping groove 24a for facilitating the clamping of the clamping portion of the first end cap 30.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; within the idea of the invention, also technical features in the above embodiments or in different embodiments can be combined, steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
