Description

[Technical field]

[0001] The present invention relates to the field of atomization technology, and in particular to a heating module and an aerosol generating device. [Background technology]

[0002] Aerosols are colloidal dispersions formed when small solid or liquid particles are dispersed and suspended in a gas medium, and aerosols are absorbed into the human body through the respiratory system, providing users with a new alternative means of absorption. An aerosol-generating device means a device that forms an aerosol by heating or baking an atomizable aerosol-generating substrate. The atomizable aerosol-generating substrate may be a liquid, gel, paste, or solid, and by atomizing these aerosol-generating substrates, an inhalable aerosol can be provided to the user in place of conventional product forms and absorption means.

[0003] Some current aerosol generating devices use a heating tube to perform thermal radiation heating on the aerosol generating substrate inside the tube. However, due to structural defects, conventional heating tubes cannot be positioned in the circumferential direction, which often results in misalignment during assembly and relative rotation with other parts after assembly, and even causes functional failures that affect the normal use of the aerosol generating device. Summary of the Invention [Problem to be solved by the invention]

[0023] For purposes of illustration, when an element is referred to as "fixed" or "mounted" on another element, it may be directly connected to the other element, or there may be intervening elements. When an element is considered to be "connected" to another element, it may be directly connected to the other element, or there may be intervening elements. As used herein, the terms "vertical," "horizontal," "up," "down," "left," "right," and similar terms are for illustrative purposes only and do not represent the only embodiment.

[0024] Referring to FIG. 1, one embodiment of the present invention provides an aerosol generating device (not shown) comprising a heating module 100 and a power supply assembly (not shown), wherein the power supply assembly is connected to one end of the heating module 100 and electrically connected to the heating module 100, and the heating module 100 can heat an aerosol generating substrate by the action of electrical energy from the power supply assembly to generate an aerosol and supply it to a user.

[0025] The aerosol-generating substrate may be in the form of a solid, specifically, in the form of a pulverized, granulated, powdered, granular, rod-shaped, or sheet-shaped solid. The aerosol-generating substrate may include, but is not limited to, materials for medical, health, and beauty purposes. For example, the aerosol-generating substrate may be a plant-based material such as a root, stem, leaf, flower, bud, or fruit of a plant.

[0026] 2, the heating module 100 includes a heat generating tube 20, a first fixing seat 40, and a second fixing seat 60. The heat generating tube 20 is a hollow circular tubular structure with a circular cross section including a first axial end 20a and a second axial end 20b that are provided to face each other in the axial direction. A storage cavity for storing an aerosol-generating substrate is formed within the heat generating tube 20, and the heat generating tube 20 can generate aerosol by performing thermal radiation heating on the aerosol-generating substrate in the storage cavity under the action of electrical energy.

[0027] The first fixing seat 40 and the second fixing seat 60 are cylindrical structures that roughly match the heat generating tube 20, with the inner diameter of the first fixing seat 40 matching the outer diameter of the first axial end 20a of the heat generating tube 20, and the inner diameter of the second fixing seat 60 matching the outer diameter of the second axial end 20b of the heat generating tube 20. In this way, the first fixing seat 40 can be fitted onto the outside of the first axial end 20a, and the second fixing seat 60 can be fitted onto the outside of the second axial end 20b, and the position of the heat generating tube 20 is restricted within the aerosol generating device by the first fixing seat 40 and the second fixing seat 60.

[0028] 2 to 4, since the heat generating tube 20 has a circular tubular structure with a circular cross section, in order to prevent the heat generating tube 20 from rotating about its own central axis relative to the first fixed seat 40 and the second fixed seat 60, at least one of the first axial end 20a and the second axial end 20b is provided with a first rotation stopper 21, and at least one of the first fixed seat 40 and the second fixed seat 60 is provided with a second rotation stopper 70 that matches the first rotation stopper 21. The first rotation stopper 21 and the second rotation stopper 70 are engageable with each other to prevent the heat generating tube 20 from rotating relative to the first fixed seat 40 and the second fixed seat 60.

[0029] In this way, the heating tube 20 is positioned in the circumferential direction by mutual engagement between the first rotation stop portion 21 and the second rotation stop portion 70, effectively preventing the heating tube 20 from rotating relative to the first fixing seat 40 and the second fixing seat 60, and avoiding functional problems due to misalignment during assembly and relative rotation that occurs after assembly.

[0030] Specifically, one of the first rotation stop portion 21 and the second rotation stop portion 70 is a rotation stop locking groove, and the other of the first rotation stop portion 21 and the second rotation stop portion 70 is a rotation stop protrusion, the shape of the rotation stop locking groove matches the shape of the rotation stop protrusion, and the rotation stop protrusion can be at least partially fitted into the rotation stop locking groove to engage with the rotation stop locking groove. In a specific embodiment, the rotation stop locking groove is a roughly rectangular recessed groove, and the rotation stop protrusion is a roughly cubic protrusion block that matches the rotation stop locking groove, and the rotation stop protrusion can be completely fitted into the rotation stop locking groove. As can be understood, the shapes of the rotation stop protrusion and the rotation stop locking groove are not limited and can be provided as necessary to meet various fitting requirements.

[0031] As shown in Figures 2 to 4, in one embodiment of the present invention, a rotation stop locking groove is provided at the first axial end 20a of the heating tube 20, and a rotation stop protrusion is protruded from the first fixed seat 40, so that the position of the heating tube 20 is limited in the circumferential direction relative to the first fixed seat 40 by the mutual engagement between the first axial end 20a and the first fixed seat 40.

[0032] Specifically, the rotation stop locking groove is provided in the end wall of the first axial end 20a, and the rotation stop locking groove extends from the end wall of the first axial end 20a along the axial direction of the heating tube 20 and communicates with the inner wall and the outer wall of the heating tube 20. The rotation stop protrusion protrudes from the inner wall of the first fixed seat 40. In this way, when the first axial end 20a is inserted into the first fixed seat 40, the rotation stop protrusion is inserted into the rotation stop locking groove and is engaged with the rotation stop locking groove, thereby preventing rotation of the heating tube 20 relative to the first fixed seat 40.

[0033] As shown in Figures 5 and 6, in one embodiment of the present invention, a rotation stop locking groove is provided at the second axial end 20b of the heating tube 20, and a rotation stop protrusion is provided on the second fixing seat 60, so that the position of the heating tube 20 is limited in the circumferential direction relative to the second fixing seat 60 by mutual engagement between the second axial end 20b and the second fixing seat 60.

[0034] Specifically, the rotation stop locking groove is provided in the end wall of the second axial end 20b, and the rotation stop locking groove extends from the end wall of the second axial end 20b along the axial direction of the heating tube 20 and communicates with the inner wall and the outer wall of the heating tube 20. The rotation stop protrusion protrudes from the inner wall of the second fixed seat 60. In this way, when the second axial end 20b is inserted into the second fixed seat 60, the rotation stop protrusion is inserted into the rotation stop locking groove and is engaged with the rotation stop locking groove, thereby preventing the rotation of the heating tube 20 relative to the second fixed seat 60.

[0035] 3, 6 and 7, in one embodiment of the present invention, the first axial end 20a and the second axial end 20b of the heating tube 20 are both provided with rotation stop locking grooves, and the first fixed seat 40 and the second fixed seat 60 are both provided with rotation stop protrusions. Therefore, the position of the heating tube 20 is limited in the circumferential direction relative to the first fixed seat 40 and the second fixed seat 60 by the mutual engagement between the first axial end 20a and the first fixed seat 40, and the mutual engagement between the second axial end 20b and the second fixed seat 60.

[0036] Specifically, the rotation stop locking groove is provided on the end wall of the first axial end 20a and the end wall of the second axial end 20b, and the rotation stop locking groove extends from the end wall of the first axial end 20a or the end wall of the second axial end 20b along the axial direction of the heating tube 20 and communicates with the inner wall and the outer wall of the heating tube 20. The rotation stop protrusion is provided on the inner wall of the first fixed seat 40 and the inner wall of the second fixed seat 60 so as to protrude therefrom.

[0037] In this way, when the first axial end 20a is inserted into the first fixed seat 40 and the second axial end 20b is inserted into the second fixed seat 60, the rotation stop protrusions of the first fixed seat 40 and the second fixed seat 60 are inserted into the rotation stop locking grooves on both ends of the heating tube 20, respectively, and engage with the rotation stop locking grooves, thereby preventing rotation of the heating tube 20 relative to the first fixed seat 40 and the second fixed seat 60. Since the two axial ends of the heating tube 20 are fixed relatively to the first fixed seat 40 and the second fixed seat 60, respectively, in the circumferential direction, the heating tube 20 is ensured not to rotate relative to the first fixed seat 40 and the second fixed seat 60.

[0038] As shown in FIG. 8, in one embodiment of the present invention, a rotation stop protrusion is provided on the first axial end 20a of the heating tube, and a rotation stop groove is provided on the first fixed seat 40, so that the position of the heating tube 20 is limited in the circumferential direction relative to the first fixed seat 40 by the mutual engagement between the first axial end 20a and the first fixed seat 40.

[0039] Specifically, the rotation stop protrusion protrudes from the end wall of the first axial end 20a, the rotation stop protrusion extends from the end wall of the first axial end 20a along the axial direction of the heating tube 20, and the thickness of the rotation stop protrusion in the radial direction of the heating tube 20 is approximately the same as the thickness of the side wall of the heating tube 20. The rotation stop groove is provided on the inner wall of the first fixed seat 40. In this way, when the first axial end 20a is inserted into the first fixed seat 40, the rotation stop protrusion is inserted into the rotation stop locking groove and is engaged with the rotation stop locking groove, thereby preventing the rotation of the heating tube 20 relative to the first fixed seat 40.

[0040] 9, in one embodiment of the present invention, a rotation stop protrusion is provided on the second axial end 20b of the heating tube 20, and a rotation stop groove is provided on the second fixing seat 60. Thus, the position of the heating tube 20 is limited in the circumferential direction relative to the second fixing seat 60 by the mutual engagement between the second axial end 20b and the second fixing seat 60.

[0041] Specifically, the rotation stop protrusion protrudes from the end wall of the second axial end 20b, the rotation stop protrusion extends from the end wall of the second axial end 20b along the axial direction of the heating tube 20, and the thickness of the rotation stop protrusion in the radial direction of the heating tube 20 is approximately the same as the thickness of the side wall of the heating tube 20. The rotation stop groove is provided on the inner wall of the second fixed seat 60. In this way, when the second axial end 20b is inserted into the second fixed seat 60, the rotation stop protrusion is inserted into the rotation stop locking groove and is engaged with the rotation stop locking groove, thereby preventing the rotation of the heating tube 20 relative to the second fixed seat 60.

[0042] 10, in one embodiment of the present invention, the first axial end 20a and the second axial end 20b of the heating tube 20 are both provided with rotation stop protrusions, and the first fixed seat 40 and the second fixed seat 60 are both provided with rotation stop locking grooves. Therefore, the position of the heating tube 20 is limited in the circumferential direction relative to the first fixed seat 40 and the second fixed seat 60 by the mutual engagement between the first axial end 20a and the first fixed seat 40, and the mutual engagement between the second axial end 20b and the second fixed seat 60.

[0043] Specifically, the rotation stopping protrusion protrudes from the end wall of the first axial end 20a and the end wall of the second axial end 20b, the rotation stopping protrusion extends from the end wall of the first axial end 20a or the end wall of the second axial end 20b along the axial direction of the heating tube 20, and the thickness of the rotation stopping protrusion in the radial direction of the heating tube 20 is approximately the same as the thickness of the side wall of the heating tube 20. The rotation stopping grooves are provided on the inner walls of the first fixed seat 40 and the second fixed seat 60.

[0044] In this way, when the first axial end 20a is inserted into the first fixed seat 40 and the second axial end 20b is inserted into the second fixed seat 60, the rotation stop protrusions on both ends of the heating tube 20 are inserted into the rotation stop locking grooves of the first fixed seat 40 and the second fixed seat 60, respectively, and engage with each other, thereby preventing rotation of the heating tube 20 relative to the first fixed seat 40 and the second fixed seat 60. Since the two axial ends of the heating tube 20 are fixed relatively to the first fixed seat 40 and the second fixed seat 60 in the circumferential direction, respectively, it is ensured that the heating tube 20 does not rotate relative to the first fixed seat 40 and the second fixed seat 60.

[0045] According to the above-mentioned heating module 100 and aerosol generating device, the heating tube 20 of the heating module 100 and the first fixed seat 40 and / or the second fixed seat 60 are fixed relatively in the circumferential direction by mutual engagement between the first rotation stop portion 21 and the second rotation stop portion 70, thereby avoiding misalignment during assembly and functional problems due to relative rotation occurring after assembly, and the overall structure is simple and reliable, without increasing the production cost of the heating module 100.

[0046] The technical features of the embodiments described above can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the embodiments described above have been described; however, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope described in this specification.

[0047] The above examples merely show some embodiments of the present application, and although the description is specific and detailed, it should not be understood as limiting the scope of the present invention. It should be noted that those skilled in the art can make some modifications and improvements that fall within the scope of the present application without departing from the idea of ​​the present application. Therefore, the scope of the patent of the present application shall be subject to the scope of the attached claims. [Explanation of symbols]
