[0030] An embodiment of the present application provides a heat-not-burn device, which is used to heat an aerosol article 40 to generate an aerosol for the user to use.

[0031] For the heat-not-burn device according to the embodiment of the present application, please refer to Figures 1 to 4 , which includes a device main body and a heating component 20.

[0032] The heating component 20 is installed in the device main body. The heating component 20 includes a heating cylinder 21 with one end open and the other end closed. The open end of the heating cylinder 21 faces the aerosol outlet 101. The heating cylinder 21 is generally a cylindrical structure. The heating cylinder 21 has a bottom wall 212 and a side wall 211.

The receiving cavity is used to accommodate the aerosol article 40. The aerosol article 40 can be inserted into the receiving cavity from the aerosol outlet 101 to realize the installation of the aerosol article 40 in the heat-not-burn device.

[0033] The bottom wall 212 of the heating cylinder 21 is arranged at an interval from the device main body in the axial direction of the heating cylinder 21, so that the heat transferred from the heating cylinder 21 to the device main body away from the accommodating cavity can be reduced. Most of the heat of the heating cylinder 21 is utilized by the aerosol article 40, which helps to improve the heat utilization rate of the heating assembly 20 and reduce the heat loss of the heat-not-burn device.

[0034] In some embodiments, please refer to Figure 3 and Figure 4 , the heating cylinder 21 is suspended in the device main body. An outer flange 213 is provided at the open end of the heating cylinder 21. The outer flange 213 is connected to the side wall 211 of the heating cylinder 21 and extends towards the radially outer side of the heating cylinder 21 to form a radially outer flange. The outer flange 213 on the heating cylinder 21 can abut against the device main body in the axial direction of the heating cylinder 21 to fix the position of the heating cylinder 21 in the device main body.

[0035] In one embodiment, the device main body includes a housing 10, a heat insulation cylinder 14 and a seal 12. The housing 10 has a cavity, and an aerosol outlet 101 is located on the housing 10. The aerosol outlet 101 is communicated with the cavity. The heat insulation cylinder 14, the heating assembly 20 and the seal 12 are all located in the cavity. The heat insulation cylinder 14 can be supported and installed in the cavity through a support portion provided on the housing 10. Both ends of the heat insulation cylinder 14 are open in its axial direction. One end opening is sealed by a plug 15, and the other end opening is in sealed cooperation with the seal 12; in another embodiment, it can also be set that one end of the heat insulation cylinder 14 is open and the other end is closed, and the open end is in sealed cooperation with the seal 12.

[0036] The heating cylinder 21 is located in the heat insulation cylinder 14 and is coaxially arranged with the heat insulation cylinder 14. The bottom wall 212 of the heating cylinder 21 is arranged at an interval from the plug 15 in the axial direction of the heating cylinder 21, and the side wall 211 of the heating cylinder 21 is also arranged at an interval from the cylinder wall of the heat insulation cylinder 14, so that the heat transferred to the heat insulation cylinder 14 due to the direct contact between the heating cylinder 21 and the heat insulation cylinder 14 can be reduced; a communication channel 121 coaxial with the heat insulation cylinder 14 is provided on the seal 12, and the accommodating cavity can be communicated with the aerosol outlet 101 through the communication channel 121.

[0037] In one embodiment, please refer to Figure 3 and Figure 4The wall of the heat-insulating tube 14 is provided with a support portion extending toward the inside of the heat-insulating tube 14, and the support portion may include a support arm 141, one end of the support arm 141 is connected to the wall of the heat-insulating tube 14, and the other end is suspended in the heat-insulating tube 14, the support arm 141 is annular, and the outer flange 213 of the heating tube 21 is supported on the support arm 141; the sealing member 12 has a portion extending into the heat-insulating tube 14, and the sealing member 12 can be abutted against the outer flange 213 in the axial direction of the heating tube 21, so that the heating tube 21 can be clamped and fixed by the support arm 141 and the sealing member 12 It is fixed in the insulation tube 14 to fix the position of the heating tube 21 in the insulation tube 14, and the sealing member 12 can also abut against the outer flange 213 in the axial direction of the heating tube 21 to achieve the sealing of the sealing member 12 and the heating tube 21. In this way, the heating tube 21 is suspended in the insulation tube 14, which can reduce the contact area between the heating tube 21 and the insulation tube 14, and reduce the heat transferred from the heating tube 21 to the bottom of the heating without combustion device due to direct contact with the accommodating cavity, which helps to reduce heat loss and improve the heat utilization rate of the heating without combustion device.

[0038] Of course, in other embodiments, the device body can also be provided with a shell 10, the shell 10 has a cavity, the heating tube 21 is located in the cavity, the bottom wall 212 and the side wall 211 of the heating tube 21 are arranged at intervals from the shell 10, and a support arm extending toward the cavity can be provided on the shell 10, and a neck portion is provided on the outer side surface of the side wall 211 of the heating tube 21. The support arm cooperates with the neck portion to suspend and fix the heating tube 21 in the shell 10. This can also reduce the heat transferred from the heating tube 21 to the bottom of the heating without combustion device due to direct contact with the accommodating cavity, which helps to reduce heat loss and improve the heat utilization rate of the heating without combustion device.

[0039] In one embodiment, please continue to refer to Figures 2 to 4 The shell 10 is provided with a positioning ring 11 at the aerosol outlet 101, and the sealing member 12 is clamped between the insulation tube 14 and the positioning ring 11 in the axial direction of the heating tube 21, so as to fix the positions of the sealing member 12 and the positioning ring 11 in the shell 10. The positioning ring 11 and the sealing member 12 are combined to form an annular groove. The device body also includes a clamping member 13. The clamping member 13 is an annular structure and is installed in the annular groove. The clamping member 13 is made of rubber material and has a protrusion 131 facing radially inward. The protrusions 131 are evenly spaced in the circumferential direction of the clamping member 13. The aerosol product 40 can enter the shell 10 from the aerosol outlet 101, pass through the connecting channel 121 of the sealing member 12 and enter the accommodating chamber formed by the heating tube 21. After the aerosol product 40 is located in the accommodating chamber, the clamping member 13 can elastically abut against the outer peripheral surface of the aerosol product 40 in the radial direction of the heating tube 21 through the protrusion 131 to limit the aerosol product 40 from escaping from the accommodating chamber.

[0040] In some embodiments, please refer to Figures 3 to 5 , on the side wall 211 of the heating cylinder 21, there is a contact convex portion protruding towards the accommodation cavity. The side wall 211 of the heating cylinder 21 also has a concave portion 2113. After the aerosol article 40 is installed in the accommodation cavity, the contact convex portion can conductively contact the outer peripheral surface of the aerosol article 40 to transfer the heat of the heating cylinder 21 to the aerosol article 40, so as to heat the aerosol article 40 by direct contact; after the contact convex portion contacts the outer peripheral surface of the aerosol article 40, the concave portion 2113 on the side wall 211 of the heating cylinder 21 can enclose with the outer peripheral surface of the aerosol article 40 to form an intake channel 31 communicating with the aerosol outlet 101. The outside cold air entering the housing 10 from the aerosol outlet 101 can enter the intake channel 31 through the gap between two adjacent protrusions 131 on the clamping member 13 and the annular gap between the seal 12 and the aerosol article 40.

[0041] In one embodiment, please refer to Figure 5 , the contact convex portion on the side wall 211 of the heating cylinder 21 includes contact ribs 2112. The contact ribs 2112 are arranged to extend in the axial direction of the heating cylinder 21. The length of the contact ribs 2112 is equal to or can also be slightly less than the dimension of the side wall 211 of the heating cylinder 21 in the axial direction of the heating cylinder 21; the number of the contact ribs 2112 can be set to be multiple. Two adjacent contact ribs 2112 are arranged at equal intervals in the circumferential direction of the heating cylinder 21, and a concave portion 2113 on the side wall 211 of the heating cylinder 21 is formed between two adjacent contact ribs 2112. The concave portion 2113 forms a groove extending in the axial direction of the heating cylinder 21. The concave portions 2113 are arranged at equal intervals in the circumferential direction of the heating cylinder 21. The intake channels 31 formed by enclosing the outer peripheral surface of the aerosol article 40 with the concave portions 2113 are also arranged at equal intervals in the circumferential direction of the heating cylinder 21. In this way, multiple intake channels 31 extending in the axial direction of the heating cylinder 21 and arranged at equal intervals in the circumferential direction are formed by enclosing between the aerosol article 40 and the side wall 211 of the heating cylinder 21. This helps to reduce the flow resistance of the air flow in the intake channel 31, thereby reducing the draw resistance of the heat-not-burn device, and also helps to achieve a uniform arrangement of the intake air flow in the circumferential direction of the aerosol article 40.

[0042] In another embodiment, the contact convex portion on the side wall 211 of the heating cylinder 21 can also include circular dot-shaped convex portions. There are multiple circular dot-shaped convex portions. Two adjacent circular dot-shaped convex portions are arranged at equal intervals in both the circumferential direction and the axial direction of the heating cylinder 21. A concave portion 2113 on the side wall 211 of the heating cylinder 21 is formed between two adjacent circular dot-shaped convex portions. The concave portion 2113 encloses with the outer peripheral surface of the aerosol article 40 to form the intake channel 31. In this way, the intake channel 31 can also extend in the axial direction of the heating cylinder 21, which can also reduce the flow resistance of the air flow in the intake channel 31, thereby reducing the draw resistance.

[0043] In some other embodiments, the contact protrusions on the side wall 211 of the heating cylinder 21 may further include a wavy strip structure or other special-shaped structures, as long as it is satisfied that the contact protrusions can contact the outer peripheral surface of the aerosol article 40, and the recess 2113 formed between two adjacent contact protrusions can enclose with the outer peripheral surface of the aerosol article 40 to form an air inlet channel 31 communicating with the aerosol outlet 101.

[0044] The side wall 211 of the heating cylinder 21 has contact protrusions and a recess 2113, and the contact protrusions can conduct heat contact with the outer peripheral surface of the aerosol article 40, and the recess 2113 can enclose with the outer peripheral surface of the aerosol article 40 to form the air inlet channel 31. On the one hand, the heat of the heating cylinder 21 can be transferred to the aerosol article 40 through the direct contact between the contact protrusions and the outer peripheral surface of the aerosol article 40 to heat the aerosol article 40; on the other hand, when the outside cold air flows through the air inlet channel 31, the heat can be transferred to the air flow in the air inlet channel 31 to form a hot air flow through the contact between the side wall 211 of the heating cylinder 21 and the air flow in the air inlet channel 31, so as to facilitate heating the aerosol article 40 by the hot air flow subsequently, thereby improving the heating uniformity of the aerosol article 40. In this way, heating the aerosol article 40 by the direct contact and hot air flow heating methods can effectively improve the heat utilization rate of the heating assembly 20, thereby reducing the heat loss of the heat-not-burn device and lowering the energy consumption of the heat-not-burn device.

[0045] In some embodiments, in order to increase the contact area between the aerosol article 40 and the upper side wall 211 of the heating cylinder 21, thereby improving the heat transfer efficiency between the heating cylinder 21 and the aerosol article 40, the contact protrusions can be set to be embedded in the aerosol article 40.

[0046] In one embodiment, please refer to Figure 5 , the contact rib 2112 has a thickness dimension extending in the circumferential direction of the heating cylinder 21. The thickness dimension of the contact rib 2112 can be set to gradually decrease in the radial direction of the heating cylinder 21 from the side wall 211 of the heating cylinder 21 to the accommodating cavity, so as to facilitate the contact rib 2112 to be embedded in the aerosol article 40. On the one hand, the contact area between the contact rib 2112 and the aerosol article 40 can be increased, thereby improving the heat transfer efficiency between the heating cylinder 21 and the aerosol article 40; on the other hand, the probability of the aerosol article 40 coming out of the accommodating cavity can be reduced by the contact rib 2112 being embedded in the aerosol article 40.

[0047] Further, in one embodiment, it is also possible to arrange that in the axial direction of the heating cylinder 21, from the open end to the closed end of the heating cylinder 21, the thickness dimension of the contact rib 2112 gradually increases, so that the contact rib 2112 is wedged in the aerosol article 40 in the axial direction of the heating cylinder 21. In this way, while further increasing the contact area between the aerosol article 40 and the heating cylinder 21 and improving the heat transfer efficiency, the probability of the aerosol article 40 coming out of the accommodating cavity can be further reduced.

[0048] In another embodiment, it is also possible to arrange that the contact protrusion includes a dot-shaped protrusion similar to a cone shape. The dot-shaped protrusion has a tip located radially inside in the radial direction of the heating cylinder 21. The aerosol article 40 can be embedded through the tip of the dot-shaped protrusion to increase the contact area between the contact protrusion and the aerosol article 40.

[0049] In order to ensure that the hot air flow formed in the air intake channel 31 can heat the aerosol article 40, it is also necessary to arrange support protrusions facing the accommodating cavity on the bottom wall 212 and / or the side wall 211 of the heating cylinder 21. The support protrusions are arranged to support the aerosol article 40 in the axial direction of the heating cylinder 21, so as to prevent the aerosol article 40 from contacting the bottom wall 212 of the heating cylinder 21. Thus, an air intake cavity 32 communicating with the air intake channel 31 is formed between the aerosol article 40 and the bottom wall 212 of the heating cylinder 21. The hot air flow formed in the air intake channel 31 can enter the air intake cavity 32, and then enter the aerosol article 40 from the axial end of the aerosol article 40 to realize heating the aerosol article 40. The aerosol generated by heating can pass through the aerosol outlet 101 and be discharged from the other end of the aerosol article 40.

[0050] In some embodiments, please refer to Figure 5 and it is possible to arrange that the support protrusions are located on the bottom wall 212 of the heating cylinder 21. There are multiple support protrusions, and two adjacent support protrusions are arranged at intervals on the bottom wall 212 of the heating cylinder 21 to form a communication gap 2122 between two adjacent support protrusions. The air intake channel 31 and the air intake cavity 32 can be communicated through the communication gap 2122.

[0051] For example, in one embodiment, please continue to refer to Figure 5 and arrange that the support protrusion includes a support rib 2121. The support rib 2121 extends in the radial direction of the heating cylinder 21. The dimension of the support rib 2121 in the radial direction of the heating cylinder 21 is smaller than the radial dimension of the accommodating cavity. Thus, an air intake cavity 32 is formed between the bottom wall 212 without the support rib 2121 and the aerosol article 40, and a communication gap 2122 is formed between two adjacent support ribs 2121. The communication gap 2122 communicates the air intake channel 31 and the air intake cavity 32.

[0052] Further, in one embodiment, please continue to refer to Figure 5, the number of the support ribs 2121 can also be set to be equal to the number of the contact ribs 2112, and the support ribs 2121 and the contact ribs 2112 are connected in a one-to-one correspondence, so as to ensure that the communication gap 2122 and the air inlet passage 31 are directly communicated in the axial direction of the heating cylinder 21, which can reduce the resistance of the hot air flow from the air inlet passage 31 into the air inlet cavity 32, thereby reducing the draw resistance.

[0053] In another embodiment, the support protrusion can also be set to include a cylindrical dot-shaped protrusion, and the cylindrical dot-shaped protrusion is located on the bottom wall 212 of the heating cylinder 21 to support the axial end face of the aerosol article 40. A communication gap 2122 is formed between two adjacent cylindrical dot-shaped protrusions. At the same time, an air inlet cavity 32 is also formed between the bottom wall 212 without the cylindrical dot-shaped protrusion and the aerosol article 40. In this way, the communication between the air inlet passage 31 and the air inlet cavity 32 can be realized through the communication gap 2122.

[0054] Of course, in other embodiments, some of the support protrusions can also be located on the side wall 211 of the heating cylinder 21. For example, the support protrusion includes a support rib 2121, and the support rib 2121 is arranged at intervals with the bottom wall 212 of the heating cylinder 21. The support rib 2121 is connected to the contact rib 2112, and a communication gap 2122 is formed between two adjacent support ribs 2121. The aerosol article 40 can be supported by the support rib 2121 to form an air inlet cavity 32 between the bottom wall 212 of the heating cylinder 21 and the aerosol article 40, and the communication gap 2122 communicates the air inlet passage 31 and the air inlet cavity 32.

[0055] In the embodiments where the communication gap 2122 between the above two support protrusions realizes the communication between the air inlet passage 31 and the air inlet cavity 32, the hot air flow in the air inlet passage 31 can enter the air inlet cavity 32 through the communication gap 2122, and then enter the aerosol article 40 from the end of the aerosol article 40 to heat the aerosol article 40. Part of the hot air flow can be stored in the air inlet cavity 32 to ensure the continuity of the aerosol generation of the aerosol article 40.

[0056] In one embodiment, please refer to Figures 3 to 5 , the heating cylinder 21 is set to be a conductive ceramic structure, that is, the heating cylinder 21 is made of a conductive ceramic material. The heating cylinder 21 can generate heat after being energized itself, which is convenient for the processing and manufacturing of the heating assembly 20, and helps to ensure the structural consistency of the heating assembly 20 and the entire non-combustible heating device.

[0057] Or in other embodiments, the heating assembly 20 further includes a heating film adhered to the outer peripheral surface of the heating cylinder 21. The heating film generates heat after being energized, and the heating film transfers the heat to the air flow and the aerosol article 40 through the heating cylinder 21.

[0058] In some embodiments, the heating component 20 includes an external wire 22. A positive connection part (not shown in the figure) and a negative connection part (not shown in the figure) connected to the external wire 22 are provided on the outer peripheral surface of the heating cylinder 21 or the heating film. The heating cylinder 21 or the heating film can be electrically connected to a circuit board (not shown in the figure) in the device main body through the external wire 22, so as to control the heating of the heating component 20 through the circuit board.

[0059] In one embodiment, multiple external wires 22 can be provided, and multiple spaced positive connection parts and negative connection parts are provided on the corresponding heating cylinder 21 or heating film. By separately controlling the energization of different external wires 22, zoned heating of the heating cylinder 21 or the heating film can be achieved.

[0060] Further, the number of positive connection parts can be set to two, three or more than four. The multiple positive connection parts are spaced in the axial direction of the heating cylinder 21, and the positive connection parts and the negative connection parts are arranged alternately in the axial direction of the heating cylinder 21.
