Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0036] In peripherally heated electronic cigarette devices, the heating element is usually mounted on the outside of the glass tube. When the user inserts or removes the cigarette, interference can easily occur between the cigarette and the heating element, resulting in poor long-term stability of the heating element.

[0037] For this, please refer to Figures 1 to 5 This application provides a heating module 100, which includes a heating component 10 and a connecting component 20. The heating component 10 has a smoke passage 11 formed inside it. The connecting component 20 includes a first connector 21 and a second connector 22, which are respectively disposed at both ends of the heating component 10 along its length. The first connector 21 has a smoke inlet 211 that communicates with the smoke passage 11. The first connector 21 also has a plug-in groove 212 on the outside of the smoke inlet 211, which is used for one end of the heating component 10 to be plugged in.

[0038] It should be noted that the specific implementation of the heating component 10 is not limited. It can be self-heating, such as in the form of a resistance wire, or electromagnetic heating, such as in a microwave transmitter, antenna, etc., and is not limited here. In addition to connecting to the heating component 10, the first connector 21 and the second connector 22 can also connect to other components of the electronic cigarette device. The connection method is not limited and can be snap-fit, glued, screwed, etc., and is not limited here.

[0039] Specifically, when the heating module 100 is applied to an electronic cigarette device, the first connector 21 is close to the mouthpiece, while the second connector 22 is far from the mouthpiece. Furthermore, the first connector 21 has a cigarette inlet 211 that connects to the smoke passage 11, so that the cigarette can enter and exit the smoke passage 11 from the cigarette inlet 211.

[0040] In the technical solution of this embodiment, by inserting one end of the heating component 10 into the insertion slot 212, the end of the heating component 10 is spaced apart from the cigarette inlet 211. When the cigarette enters or exits from the cigarette inlet 211, the barrier of the inlet wall of the cigarette inlet 211 can prevent interference between the cigarette and the end of the heating component 10, and prevent the heating component 10 from being damaged by the pulling action of the cigarette.

[0041] In some embodiments, the cigarette inlet 211 is at least partially narrowed in the direction close to the cigarette passage 11.

[0042] In the scheme of this embodiment, the cigarette inlet 211 is at least partially narrowed in the direction close to the smoke passage 11, that is, part of the cigarette inlet 211 is designed as a flared mouth. During the insertion of the cigarette, the cigarette inlet 211 can guide the cigarette, thereby guiding the cigarette to a position near the middle of the smoke passage 11, thereby avoiding interference between the cigarette and objects on the channel wall of the smoke passage 11 during the extraction process.

[0043] It should be noted that the heating component 10 may only include the heating element 13, or it may include components for heat equalization and / or heat insulation, etc., and is not limited here.

[0044] In some embodiments, the heating assembly 10 includes a heat spreader 12, a heating element 13, and a heat insulation element 14. The inner wall of the heat spreader 12 defines at least a portion of the smoke passage 11. The heating element 13 is disposed on the outside of the heat spreader 12 for heating the smoke in the smoke passage 11. The heat insulation element 14 is sleeved on the outside of the heating element 13.

[0045] In the scheme of this embodiment, the heating element 13 generates heat and then transfers it to the heat spreader 12. At this time, the heat spreader 12 heats the heat generated by the heating element 13 evenly, thereby avoiding the phenomenon of local high temperature. Then, the heat is transferred to the smoke stick located in the smoke passage 11 through the heat spreader 12. The heat insulation element 14 is sleeved on the outside of the heating element 13, thereby preventing the heat generated by the heating element 13 from leaking out, thereby concentrating the heat in the smoke passage 11 and preventing heat leakage.

[0046] Specifically, the specific implementation of the heat spreader 12 is not limited. It can be made of materials with excellent heat transfer effects, such as aluminum tubes or copper tubes. The specific implementation of the heat insulation component 14 is not limited. It can be made of aerogel, PI film winding, etc. The specific implementation of the heating component 13 is not limited. It can be made of resistance sheet, carbon fiber heating, etc. The specific implementation of the heating component 13 is not limited.

[0047] It should be emphasized that the inner wall of the heat exchanger 12 defines at least a portion of the smoke passage 11. Specifically, when the heat exchanger 12 is also inserted into the insertion slot 212, the smoke passage 11 can be entirely defined by the inner wall of the heat exchanger 12. However, when the heat exchanger 12 and the first connector 21 are spaced apart, the heat exchanger 12 only defines a portion of the smoke passage 11, and the other part of the smoke passage 11 can be defined by the heat insulation member 14 or the insulating member 15, which is not limited here.

[0048] In a further embodiment, the heat insulation member 14 extends at least partially beyond one end of the heating member 13 in the length direction, and the portion of the heat insulation member 14 extending beyond the heating member 13 forms a mounting portion for insertion into the insertion slot 212.

[0049] In the technical solution of this embodiment, the heating component 10 is installed through the heat insulation component 14. Compared with the solution of installing the heat spreader 12 to the first connector 21, since the heat spreader 12 is no longer installed with the first connector 21, the heat transfer between the heat spreader 12 and the first connector 21 can be blocked to a certain extent, thereby reducing heat loss and improving the heat transfer efficiency of the heating module 100.

[0050] Of course, in some embodiments, the heat spreader 12 is spaced apart from the first connector 21 and / or the second connector 22. Correspondingly, in the scheme of this embodiment, the heat spreader 12 is not in direct contact with the first connector 21 and / or the second connector 22, thereby preventing the heat from the heat spreader 12 from being transferred to the first connector 21 and / or the second connector 22, allowing the heat to be concentrated on the heat spreader 12 and reducing the heat loss of the heating module 100.

[0051] It should be noted that, in these embodiments, since the heat spreader 12 and the first connector 21 are spaced apart, the end of the heat spreader 12 will form a protrusion in the smoke passage 11. During the insertion and removal of the smoke stick, it is easy to interfere with the end of the heat spreader 12, or even cause peeling.

[0052] Correspondingly, at least part of the cigarette inlet 211 can be narrowed in the direction close to the smoke passage 11, so that the cigarette inlet 211 can guide the smoke and allow the cigarette to be inserted into the smoke passage 11 approximately in the center, so as to avoid interference between the cigarette and the end of the heat spreader 12 during the extraction process.

[0053] More specifically, the mounting part and the first connector 21 can be pressed together to form a flared structure, thereby achieving the constriction setting.

[0054] In addition, in order to improve the tightness of the connection between the first connector 21 and the mounting part, in some embodiments, the insertion groove 212 is also filled with sealant. By providing the sealant, the tightness of the connection between the first connector 21 and the mounting part can be improved. Furthermore, the design of the insertion groove 212 can also be used to hold glue and prevent sealant from overflowing.

[0055] Furthermore, the portion of the smoke passage 11 located in the mounting part has a gradually increasing cross-sectional area in the direction toward the first connector 21. By setting the smoke passage 11 as an flared opening, it is convenient for cigarettes to enter and exit, and it can also serve to guide the cigarettes.

[0056] In some embodiments, since the heating element 13 is made of resistance wire, if the heat spreader is made of metal, the heat spreader may easily short-circuit the heating element 13. Therefore, in some embodiments, the heating assembly 10 further includes an insulating element 15, which is disposed between the heating element 13 and the heat spreader 12. By providing the insulating element 15, the heating element 13 and the heat spreader can be separated, thereby preventing the heating element 13 from being short-circuited by the heat spreader.

[0057] The insulating component 15 is disposed between the heating element 13 and the heat spreader 12. If the thickness of the insulating component 15 is too thick, it will inevitably affect the heat transfer between the heating element 13 and the heat spreader 12, resulting in a large heat loss. Therefore, in a further embodiment, the thickness of the insulating component 15 is less than the thickness of the heat insulation component 14. With this arrangement, the insulating component 15 is thinner, thereby reducing the heat loss during the heat transfer process between the heating element 13 and the heat spreader. The heat insulation component 14 is thicker, thereby insulating the heating element 13 and preventing its heat from leaking out.

[0058] Specifically, at this time, the heat spreader is located on the innermost side, followed by the insulation member 15 on the outer side of the heat spreader, the heating member 13 on the outer side of the heat spreader, and the heat insulation member 14 on the outer side of the heating member 13.

[0059] With this configuration, the heat spreader serves to transfer and spread heat, the insulating component 15 serves to insulate between the heating component 13 and the heat spreader, and the heat insulation component 14 serves to insulate the heating component 13 from heat loss and prevent the heat generated by the heating component 13 from leaking out.

[0060] In addition, in some embodiments, the second connector 22 has a mounting end connected to the heating assembly 10, and the mounting end is provided with a boss 221, which is used to insert into the smoke passage 11 and abut against the inner wall of the smoke passage 11.

[0061] In the scheme of this embodiment, a boss 221 is provided on the mounting end of the second connector 22, so that during the installation process, the boss 221 can be inserted into the smoke passage 11, thereby supporting and limiting the heating component 10.

[0062] It should be emphasized that in some embodiments, the heating component 10 and the boss 221 are only installed on the heat insulation film. In this case, since the heat insulation film is relatively soft and easily deformed, the boss 221 abuts against the heat insulation film and can also stretch the heat insulation film to maintain the shape of the smoke passage 11.

[0063] Of course, while bonding, adhesive can also be applied to the heating component 10 or the boss 221 to bond the two together and further improve the stability of the connection between them.

[0064] In a further embodiment, a rib 222 is also provided on the mounting end. The rib 222 is arranged around the outside of the boss 221 and is spaced apart from the boss 221. Together with the boss 221, they define a mounting groove for mounting the heating assembly 10.

[0065] In the scheme of this embodiment, by setting the rib 222, the rib 222 and the boss 221 are spaced apart and together define a mounting groove. In actual use, the heating component 10 can be installed into the mounting groove, so that the mounting groove clamps and limits the heating component 10, thereby improving the stability of the installation of the heating component 10.

[0066] In some embodiments, the heating module 100 further includes a support assembly, which is sleeved on the outside of the heating module 10 and connected to the first connector 21 and the second connector 22, so as to jointly form the outer shell of the heating module 100 with the first connector 21 and the second connector; the support assembly includes a plurality of interlocking support members 30.

[0067] In the technical solution of this embodiment, by setting the support component as a plurality of interlocking support members 30, in the actual assembly process of the heating module 100, the heating component 10 and the connecting component 20 can be assembled together first, and then the support component can be installed, thereby simplifying the installation process.

[0068] Please see Figure 4 Of course, in some embodiments, the first connector 21 is also provided with an air inlet groove 40 at the cigarette inlet 211 that connects to the smoke passage 11, thereby increasing the air flow in the smoke passage 11 and generating more smoke.

[0069] Correspondingly, at this time, the second connector 22 can block the other end of the smoke passage 11, thereby forming a structure in which the first connector 21 is for air intake and the second connector 22 is for blocking.

[0070] Please see Figure 5 Of course, in some other embodiments, the cigarette inlet 211 is set to be 0.05 to 0.1 mm smaller than the cigarette diameter, forming a tight fit with the cigarette, and the second connector 22 is sealed to prevent air from entering, thereby forming an NSC (natural smoke) heating structure.

[0071] This application also proposes an electronic cigarette device, which includes a heating module 100. The heating module 100 adopts one or all of the technical solutions of the foregoing embodiments, and therefore possesses all or all of the technical advantages of the foregoing embodiments.

[0072] The heating module and electronic cigarette device provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
