DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to solve the above problems, the present invention proposes an infrared heating device for heating cigarettes without burning them. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , including a rotating part 1, an adapter part 2, a base 3, and an axially openable portable chamber 4, the portable chamber 4 including a rotating plate 41 and an inner groove plate 42, the rotating plate 41 and the inner groove plate 42 are not coaxial and the rotating plate 41 can be axially rotated and stored in the inner groove plate 42; one end of the adapter part 2 is rotatably connected to the base 3, and the other end of the adapter part 2 is coaxially docked with the rotating part 1 to form an outer shell, the portable chamber 4 is placed inside the outer shell and the inner groove plate 42 is fixed relative to the base 3, the rotating plate 41 can rotate synchronously with the rotating part 1, and thus cooperate with the inner groove plate 42 to form an infrared heating chamber.

[0034] In an embodiment of the present invention, the rotating part 1 and the adapter part 2 are detachably installed, and an annular docking structure can be provided at the upper end of the adapter part 2, and structures such as threads and limit buckles can be provided so that the rotating part 1 and the adapter part 2 can rotate synchronously after the docking installation is completed, and a detachable installation effect can be achieved at the same time. Preferably, the rotating part 1 and the adapter part 2 can be screwed and fixed by threaded fixing; when disassembling, just reverse it. The structure after the rotating part 1 and the adapter part 2 are docked and fixed can be defined as the outer shell of the heating device, and the state between the outer shell and the base 3 is relatively stable and does not separate from each other; when disassembly is required, only the rotating part 1 can be separated.

[0035] The lower end of the adapter portion 2 is rotatably connected to the base body 3, so that the outer shell and the base body 3 can generate relative rotation while maintaining connection stability.

[0036] The center of the outer shell is opened as a cavity for installing the portable cavity 4. The heating device of the present invention adopts an axially open and close heating cavity structure, that is, the portable cavity 4 is opened and closed by rotating in a circle around the axis of the fixed seat 43.

[0037] When the portable cavity 4 is closed, the heating device can perform infrared heating and release smoke; when the portable cavity 4 is opened, the heating device does not perform infrared heating, and the smoking products inside can be easily taken out.

[0038] In the embodiment of the present invention, the portable cavity 4 includes a rotating plate 41, an inner groove plate 42, and a fixing seat 43. The rotating plate 41 and the inner groove plate 42 cooperate to form a cavity structure that is approximately cylindrical, that is, the infrared heating cavity of the heating device of the present invention. The bottom of the cavity structure is closed by the fixing seat 43. The upper end of the cavity is the insertion port of the smoking product.

[0039] Specifically, the rotating plate 41 and the inner groove plate 42 are not coaxial and the rotating plate 41 can be axially rotated and stored in the inner groove plate 42. The rotating plate 41 and the inner groove plate 42 are both erected on the fixed seat 43; wherein the inner groove plate 42 and the fixed seat 43 are coaxially arranged, and the inner groove plate 42 is provided with a built-in inner groove cavity 44.

[0040] The inner wall and the outer wall of the inner groove plate 42 are coaxially arranged; the inner wall and the outer wall of the rotating plate 41 are not coaxially arranged, so that the axial thickness of the rotating plate 41 is larger on one side and smaller on the other side. The side with smaller axial thickness is defined as the built-in end, which is inserted into the inner groove cavity 44; the side with larger axial thickness is the docking end, which is docked with the inner groove cavity 44 to form an infrared heating cavity.

[0041] In an embodiment of the present invention, the inner groove cavity 44 extends downward to the fixed seat 43, and an annular groove is formed on the fixed seat 43, so that the rotating plate 41 can slide circumferentially along the annular groove; since the thickness of the rotating plate 41 is different, the width of the annular groove and the width of the inner groove cavity 44 can be expanded, so that the rotating plate 41 can slide radially.

[0042] When the rotating plate 41 rotates along the annular groove, since the inner end gradually penetrates into the inner groove cavity 44, the entire plate 41 needs to slide radially outward to continue to rotate.

[0043] Based on the structure of the portable chamber 4 of the present invention, the rotating plate 41 and the inner groove plate 42 are both provided with infrared coatings to form an infrared heating chamber. Further, the infrared coating can be provided with electrodes extending outside the chamber structure to establish electrical connection with the control module 8.

[0044] When the infrared heating device is turned on, the infrared rays emitted from the cavity are absorbed by the smoking article, causing the temperature to rise and smoke to be released. It can be understood that the cylindrical cavity can effectively even out the distribution of infrared rays and reduce the local heating error.

[0045] Furthermore, temperature sensors may be distributed on the inner groove plate 42 to detect the temperature in the cavity in real time and make adaptive adjustments according to temperature changes.

[0046] In the embodiment of the present invention, a fixing portion is provided on the outer ring wall of the fixing seat 43, and a base 5 for mounting the portable chamber 4 is provided at the docking port of the base 3 and the adapter 2, and a recessed matching portion is provided on the base 5 corresponding to the fixing portion, so that the portable chamber 4 can be fixedly connected to the base 3. The fixing portion and the matching portion can be threaded.

[0047] In the embodiment of the present invention, the bottom surface of the fixing seat 43 and the bottom of the groove of the recessed matching portion of the base 5 are provided with corresponding contact points. When the portable chamber 4 and the base 5 are fixedly connected, the contact points on the fixing seat 43 are connected to the contact points on the base 5 in a one-to-one correspondence. The contact points can be used for the conduction of the moving electrode plate and the fixed electrode plate.

[0048] Specifically, a sliding contact can be set between the rotating plate 41 and the annular groove for conduction, and the annular groove can be directly connected to the contact point for conduction. The inner groove plate 42 can be directly fixed to the contact point on the fixing seat 43 to achieve alignment and fixed point conduction.

[0049] Preferably, the inner groove plate 42 and the fixing seat 43 are detachably connected, and the position of the docking installation only needs to be fixed.

[0050] The circumferential proportion of the rotating plate 41 is greater than that of the inner groove plate 42, so that when the butt end of the rotating plate 41 is butted with the inner groove cavity 44 to form an infrared heating cavity, the built-in end is still in the inner groove cavity 44, and the structural plate can be effectively opened and closed without causing stagnation or jamming. A butt arc surface is provided on the inner side of the butt end of the rotating plate 41 along the axial direction, and a butt notch is provided on the inner side wall of the inner groove cavity 44 along the axial direction, so that the rotating plate 41 can be stably butted with the inner groove plate 42.

[0051] A locking portion 12 is provided on the outer side wall of the butt end of the rotating plate 41 near the end, and a driving member 45 is provided on the inner side wall of the rotating part 1 corresponding to the locking portion 12, so that when the locking portion 12 and the driving member 45 form a locking position, the rotating plate 41 can rotate synchronously with the rotating part 1.

[0052] It should be clear that after the smoking product is inserted into the portable cavity 4, in order to ensure its stability and prevent it from falling off easily, a holding device 6 can be set between the insertion port 11 and the portable cavity 4 to achieve non-impact holding of the smoking product. Furthermore, the holding hole of the holding device 6 and the inner cavity of the insertion port 11 and the portable cavity 4 should be coaxially arranged to facilitate the insertion of the smoking product.

[0053] It can be understood that the change of the holding state of the holding device 6 can be controlled by a drive, and the driving mode may include manual control and trigger control, wherein the electrical signal of the trigger control can be conducted through the abutment contact between the holding device 6 and the inner groove plate 42, so that the holding device 6 can establish a control connection with the control module 8; manual control can be achieved by setting a control part on the outer wall of the rotating part 1, which can be controlled autonomously by the smoker.

[0054] In the embodiment of the present invention, a sensor 7 can be arranged at the center of the annular groove, facing the infrared heating cavity. The sensor 7 placed at the bottom of the infrared heating cavity is used to detect the insertion completion of the smoking product. When the insertion of the smoking product meets the given conditions, it is ready for heating; further, when the portable cavity 4 is closed, the heating cavity is ready for heating; when the above two conditions are met, the smoking product can be automatically heated.

[0055] In an embodiment of the present invention, a moving electrode plate is provided on the inner wall of the rotating plate 41, and a fixed electrode plate is provided on the inner wall of the inner groove plate 42. The distance between the electrode plates can change with the rotation of the rotating plate 41. Therefore, the opening and closing state of the portable cavity 4 can be judged according to the capacitance value between the electrode plates.

[0056] Based on the above detectable data, when the detected capacitance value data and induction data meet the requirements, heating can be started autonomously.

[0057] Furthermore, when the sensing data obtained by detection meets the requirements, the holding device 6 can be driven to clamp the smoking product to stabilize the insertion effect of the smoking product. The holding device 6 can be integrated on the rotating part 1.

[0058] When disassembling the infrared heating device of the present invention, the fixed connection between the rotating part 1 and the adapter part 2 should be released first. After removing the rotating part 1, the fixed connection between the portable cavity 4 and the base 5 should be released, and the portable cavity 4 can be disassembled. Further, the fixed connection between the inner groove plate 42 and the fixed seat 43 can be released, and the rotating plate 41 can be disassembled for more comprehensive cleaning and maintenance.

[0059] The contents described above may be implemented individually or in combination in various ways, and these variations are all within the protection scope of the present invention.

[0060] It should be noted that in this text, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
