Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, specifically to an aerosol generating device. Background Technology

[0002] An aerosol generating device is a device that heats an aerosol matrix to generate aerosols. To simplify the structure of the device, some aerosol generating devices introduce air through a gap between the housing and the outer wall of the aerosol matrix. The airflow is ultimately guided to the bottom of the aerosol matrix. However, the method of air intake between the housing and the outer wall of the aerosol matrix is ​​limited by the fit tolerance between the diameter of the aerosol matrix and the housing's insertion hole. This results in a narrow gap between the housing and the outer wall of the aerosol matrix. This narrow gap causes high-speed airflow, generating noise and providing a poor user experience.

The first sealing element is disposed between the inner wall of the installation cavity and the support assembly to seal the gap between the housing and the support assembly. The first sealing element has independent second insertion holes and second air inlets. The two ends of the second insertion hole are respectively connected to the first insertion hole and the heating cavity. The two ends of the second air inlet are respectively connected to the first air inlet and the air inlet channel. The end of the air inlet channel away from the second air inlet is connected to the heating cavity.

[0005] In one embodiment, the bracket assembly has a mounting groove on the side facing the first socket. A heating chamber and an air intake channel are formed on the bottom wall of the mounting groove away from the first socket.

[0006] In one embodiment, the first seal has a first annular protrusion and a second annular protrusion on the side facing the first insertion hole. The second annular protrusion is spaced around the outer periphery of the first annular protrusion. The first annular protrusion and the second annular protrusion are interference-fitted with the inner wall of the mounting cavity. The first annular protrusion surrounds the outer periphery of the end of the second insertion hole facing the first insertion hole. The end of the second air inlet facing the first insertion hole is located between the first annular protrusion and the second annular protrusion.

[0007] In one embodiment, the second socket has at least two protrusions on its wall, the protrusions being used to hold the aerosol matrix.

[0008] In one embodiment, the aerosol generating device further includes a second seal, which is sealed to the side of the support assembly away from the first insertion hole, and an air guide cavity is formed between the second seal and the support assembly, through which the air inlet channel and the heating chamber are connected.

[0009] In one embodiment, the aerosol generating device further includes an airflow sensor, a portion of the sidewall of the air guiding cavity is an elastic structure, and the second seal further includes an assembly cavity, a portion of the cavity wall of the assembly cavity is an elastic structure, and the assembly cavity is equipped with an airflow sensor.

[0011] In one embodiment, the support assembly includes a heat-insulating support and a base, and the aerosol generating device further includes a heating element.

The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0028] Please refer to Figure 1-3 This application provides an aerosol generating device for heating an aerosol matrix 10 to generate aerosols. The aerosol matrix 10 can be used as a consumable in the aerosol generating device. In one embodiment, the aerosol matrix 10 may include a matrix section, a cooling section, and a filter section. The matrix section is used to contain grass-like matrix, the cooling section is used to cool the aerosols generated in the matrix section, and the filter section can filter the aerosols. A user can draw in the aerosols generated in the matrix section by suctioning the filter section. Of course, in other embodiments, the aerosol matrix 10 may have other structures, not limited to those mentioned above, and this application does not impose any limitations on this. In this application, the aerosol generating device may or may not include the aerosol matrix 10.

[0029] The aerosol generating device includes a housing 20, a support assembly 30, and a first seal 40. For example... Figure 2As shown, the housing 20 has a mounting cavity 21, and the bracket assembly 30 and the first sealing element 40 are both disposed within the mounting cavity 21. Furthermore, the aerosol generating device also includes components such as a battery and a circuit board, which are disposed within the mounting cavity 21 and external to the bracket assembly 30.

[0030] like Figure 3 and Figure 4 As shown, the outer casing 20 is provided with independent first insertion holes 22 and first air inlets 23. Specifically, the first insertion holes 22 and first air inlets 23 are spaced apart on the outer wall of the top of the outer casing 20. The bracket assembly 30 is disposed on the side of the mounting cavity 21 near the first insertion holes 22 and first air inlets 23. The bracket assembly 30 is provided with a heating cavity 31 and an air inlet channel 32 spaced apart. The air inlet channel 32 surrounds the outer periphery of the heating cavity 31. The heating cavity 31 is used to contain the aerosol matrix 10 to heat the aerosol matrix 10 into an aerosol.

[0031] The first seal 40 is disposed between the inner wall of the mounting cavity 21 and the bracket assembly 30 to seal the gap between the housing 20 and the bracket assembly 30, thereby preventing condensate in the bracket assembly 30 from leaking into the electronic components inside the housing 20 and ensuring the airtightness of the air passage between the bracket assembly 30 and the housing 20. The first seal 40 is made of a high-temperature resistant elastic material, such as silicone.

[0032] like Figure 3 and Figure 5 As shown, the first sealing member 40 is provided with independent second insertion holes 41 and second air inlets 42. Specifically, both the second insertion holes 41 and the second air inlets 42 penetrate the first sealing member 40, and are spaced apart. The two ends of the second insertion hole 41 are connected to the first insertion hole 22 and the heating chamber 31, respectively. Specifically, one end of the second insertion hole 41 is opposite to the first insertion hole 22, and the other end is opposite to the heating chamber 31. The central axes of the second insertion hole 41, the first insertion hole 22, and the heating chamber 31 are aligned, allowing the aerosol matrix 10 to sequentially pass through the first insertion hole 22 and the second insertion hole 41 and be inserted into the heating chamber 31. The two ends of the second air inlet 42 are connected to the first air inlet 23 and the air intake channel 32, respectively. The end of the air intake channel 32 away from the second air inlet 42 is connected to the heating chamber 31.

[0033] like Figure 3 As shown, Figure 3The arrows indicate the direction of airflow. After the aerosol matrix 10 is inserted into the heating chamber 31, the user draws air through the filter section of the aerosol matrix 10. The airflow enters the aerosol generating device through the first air inlet 23, and then enters the heating chamber 31 through the second air inlet 42 and the air inlet channel 32 in sequence. It then enters the interior of the aerosol matrix 10 structure from the bottom surface of the aerosol matrix 10. The airflow carries the aerosol generated by the matrix section of the aerosol matrix 10 and overflows from the filter section so that the user can draw in the aerosol.

[0034] This aerosol generating device has an independent first insertion hole 22 and a first air inlet 23 on the outer casing 20, and an independent second insertion hole 41 and a second air inlet 42 on the first sealing member 40. The first air inlet 23 and the second air inlet 42 are sequentially connected to the air intake channel 32, and the first insertion hole 22 and the second insertion hole 41 are sequentially connected to the heating chamber 31. The aerosol matrix 10 can be inserted into the heating chamber 31 through the first insertion hole 22 and the second insertion hole 41. The air intake channel 32 connects to the heating chamber 31 from the side away from the first insertion hole 22. Therefore, the air intake process for the aerosol matrix 10 does not flow through the aerosol matrix 10. The independently set first air inlet 23 and second air inlet 42 are not limited by the fit tolerance between the aerosol matrix 10 and the insertion hole. The inner diameter of the first air inlet 23 and the second air inlet 42 can be relatively increased, avoiding the problem of noise caused by a narrow channel during the air intake process.

[0035] Furthermore, since the air intake channel 32 is arranged around the heating chamber 31, the heat overflowing from the heating chamber 31 can be used to preheat the cold air in the air intake channel 32. After the cold air is preheated, it can also enter the aerosol matrix 10 to heat the matrix section. Therefore, the energy recycling rate can be improved, the energy consumption can be reduced, and the heat can be prevented from spreading outward from the support assembly 30. This can directly or indirectly reduce the surface temperature of the aerosol generating device housing 20.

[0036] like Figure 3 and Figure 6 As shown, in one embodiment, the bracket assembly 30 has a mounting groove 33 on the side facing the first insertion hole 22. A heating chamber 31 and an air intake channel 32 are formed on the bottom wall of the mounting groove 33 away from the first insertion hole 22. The first seal 40 is installed in the mounting groove 33, and the side of the first seal 40 facing the first insertion hole 22 is press-fitted with the inner wall of the mounting cavity 21. By providing the mounting groove 33 on the bracket assembly 30, the first seal 40 can be installed more easily, and the second insertion hole 41 of the first seal 40 can communicate with the first insertion hole 22 and the heating chamber 31, as well as the second air intake hole 42 can communicate with the first air intake hole 23 and the air intake channel 32.

[0037] Furthermore, such as Figure 6As shown, the first sealing member 40 has a first annular protrusion 43 and a second annular protrusion 44 on the side facing the first insertion hole 22. The second annular protrusion 44 is spaced around the outer periphery of the first annular protrusion 43, and the first annular protrusion 43 and the second annular protrusion 44 are press-fitted with the inner wall of the mounting cavity 21. The first annular protrusion 43 surrounds the outer periphery of the end of the second insertion hole 41 facing the first insertion hole 22, thereby ensuring the sealing of the connection between the first insertion hole 22 and the second insertion hole 41 when the first annular protrusion 43 abuts against the inner wall of the mounting cavity 21. The end of the second air inlet 42 facing the first insertion hole 22 is located between the first annular protrusion 43 and the second annular protrusion 44, thereby ensuring the sealing of the connection between the first air inlet 23 and the second air inlet 42 when the first annular protrusion 43 and the second annular protrusion 44 abut against the inner wall of the mounting cavity 21.

[0038] More preferably, the first sealing member 40 also has a first protruding ridge 45 and a second protruding ridge 46 on the side facing the first insertion hole 22. One end of the first protruding ridge 45 is connected to the first annular protrusion 43, and the other end of the first protruding ridge 45 is connected to the second annular protrusion 44. One end of the second protruding ridge 46 is connected to the first annular protrusion 43, and the other end of the second protruding ridge 46 is connected to the second annular protrusion 44. The first protruding ridge 45, the first annular protrusion 43, the second protruding ridge 46, and the second annular protrusion 44 surround the end of the second air inlet 42 facing the first air inlet 23, so as to further improve the airtightness of the connection between the first air inlet 23 and the second air inlet 42.

[0039] In one embodiment, such as Figure 6 As shown, at least two protrusions 47 are provided on the wall of the second insertion hole 41. The protrusions 47 are used to clamp the aerosol matrix 10 to prevent the aerosol matrix 10 from shaking during the suction process. The protrusions 47 can be evenly distributed in the circumferential direction of the second insertion hole 41 so as to uniformly abut against the aerosol matrix 10 in the circumferential direction.

[0040] In one embodiment, such as Figure 3 As shown, the aerosol generating device also includes a second sealing element 50, which is sealed to the side of the support assembly 30 away from the first insertion hole 22, and forms an air guiding cavity 51 between the second sealing element 50 and the support assembly 30. The air inlet channel 32 and the heating cavity 31 are connected through the air guiding cavity 51, that is, the gas in the air inlet channel 32 needs to enter the heating cavity 31 through the air guiding cavity 51.

[0041] The second seal 50 can seal the bottom of the bracket assembly 30 to prevent condensate generated inside the bracket assembly 30 from flowing out from the bottom of the bracket assembly 30. Furthermore, since the air guide cavity 51 is located below the air intake channel 32 and the heating cavity 31, condensate flowing out from the bottom of the heating cavity 31 can be collected in the air guide cavity 51 and will not flow onto other electronic components inside the housing 20, thus preventing leakage.

[0042] The second seal 50 may be made of an elastic material, such as silicone. The second seal 50 has an interference fit that can be interlocked with the bracket assembly 30 to provide a sealed connection between the second seal 50 and the bracket assembly 30. The interference fit may be, for example, a raised ring.

[0043] like Figure 7 As shown, in one embodiment, the second seal 50 includes a sealing portion 52 and an assembly portion 53 connected together. The sealing portion 52 is connected to the side of the assembly portion 53 near the first insertion hole 22. The sealing portion 52 has an annular structure and is disposed around the outer side wall of the bracket assembly 30 and is sealed to the outer side wall of the bracket assembly 30. The sealing portion 52 is provided with an interference fit structure, which is interference-fitted with the bracket assembly 30 for sealing.

[0044] Specifically, the assembly part 53 abuts against the end of the bracket assembly 30 away from the first insertion hole 22, that is, the bottom of the bracket assembly 30 is mounted on the assembly part 53. The side of the assembly part 53 facing the heating chamber 31 has an assembly groove 531, which is connected to the air intake channel 3231. The assembly groove 531 and the end of the bracket assembly 30 away from the first insertion hole 22 cooperate to form an air guide chamber 51.

[0045] In one embodiment, such as Figure 3 As shown, the aerosol generating device also includes an airflow sensor (not shown). A portion of the wall of the air guide cavity 51 is an elastic structure 532. The elastic structure 532 can be thinner than the other walls of the air guide cavity 51, allowing it to elastically deform relative to the other walls. The second sealing element 50 also includes an assembly cavity, a portion of which is the aforementioned elastic structure 532. That is, the air guide cavity 51 and the assembly cavity are separated by the elastic structure 532, and the airflow sensor is installed inside the assembly cavity.

[0046] Since the air guide chamber 51 and the air inlet channel 32 are connected, the elastic structure 532 of the air guide chamber 51 can deform during user suction to change the volume of the assembly chamber. Due to the change in the volume of the assembly chamber, the pressure in the assembly chamber will change, and the airflow sensor can sense the pressure change in the assembly chamber and thus operate. The assembly chamber and the air guide chamber 51 are also separated by the elastic structure 532 to prevent the condensate collected in the air guide chamber 51 from leaking onto the airflow sensor.

[0047] In one embodiment, the cross-sectional shape of the elastic structure 532 of the air guide cavity 51 includes an arched or wavy shape, with the cross-section parallel to the central axis of the elastic structure 532. An arched shape is one where the center protrudes relative to the edge. In this embodiment, the cross-section is parallel to the central axis of the elastic structure 532, which extends along the thickness direction of the elastic structure 532. When the elastic structure 532 is approximately arched or wavy, compared to a planar shape, the elastic structure 532 has a stronger deformation capacity and is more easily deformed under negative pressure, thus ensuring the reliability of the airflow sensor's port counting.

[0048] In one embodiment, such as Figure 3 , Figure 6 and Figure 8 As shown, the support assembly 30 includes a heat-insulating support 34 and a base 35. The aerosol generating device also includes a heating element 60. The heat-insulating support 34 is provided with an air inlet channel 32, an installation space 341, and an installation groove 33. The air inlet channel 32 surrounds the outer periphery of the installation space 341. The base 35 is located at the end of the installation space 341 away from the first insertion hole 22. The heating element 60 is located within the installation space 341, and both ends of the heating element 60 abut against the heat-insulating support 34 and the base 35, respectively. The heating element 60 has a heating cavity 31. Thus, an air gap exists between the heating cavity 31 and the air inlet channel 32, which can effectively insulate the heat from the heating element 60.

[0049] Furthermore, the aerosol generating device also includes a heat insulation layer, which is provided on the cavity wall of the installation space 341. The heat insulation layer can further prevent heat leakage from the heating element 60 and ensure the heating efficiency of the heating element 60. The material of the heat insulation layer can be, for example, a ceramic fiber composite material.

[0050] In one embodiment, such as Figure 9 As shown, a groove 351 is provided on the side of the base 35 facing the heating chamber 31. The first insertion hole 22, the second insertion hole 41, the heating chamber 31, and the groove 351 form the mounting position for the aerosol matrix 10. When the aerosol matrix 10 is inserted into the heating chamber 31, the bottom of the aerosol matrix 10 can be fixed in the groove 351. A through hole 352 is provided on the bottom wall of the groove 351 away from the heating chamber 31. The through hole 352 connects the air intake channel 32 and the groove 351. The gas in the air intake channel 32 can enter the aerosol matrix 10 in the groove 351 through the air guide cavity 51 and the through hole 352. This is a limitation of the embodiments of this application.

[0051] The above examples illustrate this application only to aid in understanding the invention and are not intended to limit the scope of the application. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the concept of this application.
