Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.
[0035] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0036] An aerosol generator is a special atomizing product containing an atomizing matrix. When in use, it is inserted into a matching atomizing device. The heater heats the aerosol generator, causing the atomizing matrix inside the aerosol generator to atomize and generate an aerosol. As the user draws in the aerosol generator, the aerosol moves with the airflow to the suction end.
[0037] The atomizing device provided in this application has a thin sheet structure at the air inlet of the housing, and multiple silencer holes that communicate with the air inlet are opened on the thin sheet structure. This makes the silencer holes the narrowest part of the movement path of the entire air passage. When external air enters the air inlet, it must pass through the silencer holes. By using the principle of small hole silencer, the airflow noise during air intake is reduced, thereby preventing sharp and piercing noise during the suction process.
[0038] The following describes some embodiments of the atomizing device provided in this application with reference to the accompanying drawings.
[0039] It should be noted that, for ease of description, in the atomizing device of the following embodiments, the height direction is the first direction, the width direction is the second direction, and the thickness direction is the third direction.
[0040] One embodiment of this application provides an atomizing device 100, such as... Figure 1 , Figure 2 , Figure 3As shown, the device includes a housing 1, a support assembly 2, and a heating element 3. In a first direction, one end of the housing 1 has an insertion port 11 and an air inlet 12. The insertion port 11 is matched with the aerosol generating rod 500 to be used, so that the aerosol generating rod 500 can be inserted into the housing 1 through the insertion port 11. The air inlet 12 is used to allow external air to flow in. A thin sheet structure 131 covers the outer end of the air inlet 12. The thin sheet structure 131 blocks the air inlet 12, and a plurality of silencers 1311 communicating with the air inlet 12 are opened on the thin sheet structure 131. The diameter of the silencers 1311 is smaller than that of the air inlet 12, so that external air can pass through the silencers 1311 on the thin sheet structure 131 and enter the air inlet 12. Both the support assembly 2 and the heating element 3 are disposed inside the housing 1. The support assembly 2 is correspondingly disposed to the insertion port 11, and the support assembly 2 has a receiving cavity 21 and an air inlet channel 22 inside. The receiving cavity 21 is connected to the insertion port 11 to accommodate the aerosol generating rod 500. The heating element 3 is disposed in the receiving cavity 21 to heat the aerosol generating rod 500 so that the atomizing matrix stored in the aerosol generating rod 500 is heated and atomized to generate aerosol. One end of the air inlet channel 22 is connected to the air inlet hole 12 of the housing 1, and the other end of the air inlet channel 22 is connected to the end of the receiving cavity 21 away from the insertion port 11, so that external air can enter the receiving cavity 21 through the air inlet channel 22, so that when the suction action is performed, the airflow can be drawn into the aerosol generating rod 500 and carry the generated aerosol to the suction end.
[0041] It is understandable that existing atomizing devices usually have air inlets directly on the housing. However, when the suction action is performed, the external air is heated and enters the air intake channel under negative pressure, which can easily generate a loud airflow noise. In severe cases, it may cause sharp and piercing noise, resulting in a poor user experience.
[0042] In this embodiment, the atomizing device 100 improves and optimizes its structure by using a thin sheet structure 131 on the housing 1 to open a silencing hole 1311 that communicates with the air inlet 12, so that the silencing hole 1311 forms the narrowest part of the overall airway. The principle of small hole silencing is used to reduce airflow noise, thereby preventing noise during the suction process and improving the user experience.
[0043] It should be noted that in practical applications, the shape of the thin sheet structure 131 can be set as needed, as long as it can cover the air inlet 12; the number and arrangement of the muffler holes 1311 on the thin sheet structure 131 can also be set according to the shape and size of the air inlet 12.
[0044] In further embodiments of this application, such as Figure 3 , Figure 4 and Figure 5As shown, in the first direction, the thickness of the sheet structure 131 is less than 0.4 mm, so that the narrowest point in the airflow path is extremely short, making the multiple silencer holes 1311 form a sieve-like structure, which can further reduce the airflow noise when the airflow passes through the silencer holes 1311 and enhance the noise reduction effect. Preferably, the sheet structure 131 can be made of a metal sheet with a thickness of 0.3 mm, such as a sheet of stainless steel or aluminum. In addition, the sheet structure 131 can be detachably connected to the housing 1 for easy assembly.
[0045] Furthermore, in a specific implementation, such as Figure 2 , Figure 5 and Figure 6 In the example shown, on the projection plane perpendicular to the first direction, multiple silencers 1311 on the sheet structure 131 are all within the projection range of the air inlet 12. That is, each silencer 1311 is directly opposite the air inlet 12 in the first direction. After passing through the silencer 1311, the airflow can directly enter the air inlet 12 without turning, resulting in stronger airflow and helping to maintain smooth air intake. The multiple silencers 1311 can be arranged in an array according to the opening shape of the air inlet 12, for example... Figure 2 In the example shown, the air intake 12 has an arc-shaped strip opening, and the multiple silencers 1311 are also arranged in two arc-shaped rows. The spacing between adjacent silencers 1311 is equal or close, forming a relatively regular arrangement. When external air passes through the multiple silencers 1311, the airflow distribution is relatively uniform, which helps to ensure a more balanced airflow and prevents local airflow disturbances or impacts.
[0046] It should be noted that the above is only a specific example. The opening shape of the air intake 12 is not limited to the arc-shaped strip structure in the above example. It can also be set as a rectangle, circle, ellipse or other shapes as needed. Correspondingly, the arrangement of the muffler holes 1311 can also adopt a matrix, ring array or other forms of array arrangement.
[0047] In further embodiments of this application, such as Figures 4 to 6In the example, the atomizing device 100 also includes an annular sleeve structure 13, which is disposed in the insertion port 11, with the outer wall of the sleeve structure 13 abutting against the inner wall of the insertion port 11. A thin sheet structure 131 is connected to the end of the sleeve structure 13 facing outward from the insertion port 11, and the thin sheet structure 131 is arranged circumferentially along the sleeve structure 13 to form an annular thin sheet structure 131 adapted to the insertion port 11. In the first direction, the end of the sleeve structure 13 facing outward from the insertion port 11 is inclined outward to form a locally gradually expanding, trumpet-like structure, so that the inclined surface can guide the aerosol generating rod 500 when it passes through the sleeve structure 13, making it easier for the aerosol generating rod 500 to be aligned and pass through the insertion port 11.
[0048] In further embodiments of this application, such as Figure 3 , Figure 4 as well as Figure 7 and Figure 8 As shown, in the atomizing device 100, the support assembly 2 includes a first sealing element 23, a heat insulation sleeve 24, and a support base 25. The first sealing element 23 abuts against the inner end of the insertion port 11, and the heat insulation sleeve 24 is connected to the end of the first sealing element 23 away from the insertion port 11, so as to seal the gap between the heat insulation sleeve 24 and the housing 1 through the first sealing element 23. The first sealing element 23 has a through hole 231 corresponding to the insertion port 11, and a receiving cavity 21 is formed inside the heat insulation sleeve 24. One end of the through hole 231 communicates with the insertion port 11, and the other end communicates with the heat insulation sleeve 24. The first sealing element 23 also has a first air passage 232 corresponding to the air inlet 12. The first air passage 232 extends along a first direction, and one end communicates with the air inlet 12 of the housing 1. A second air passage 241 is formed inside the side wall of the heat insulation sleeve 24. The second air passage 241 communicates with the first air passage 232 to form an air inlet channel 22. In the first direction, the support base 25 is connected to the end of the receiving cavity 21 of the heat insulation sleeve 24 away from the insertion port 11 to seal the receiving cavity 21; wherein, as Figure 4 , Figure 9 and Figure 10 In the example, the support base 25 has a slot 251 at the end facing the insertion port 11. The bottom wall of the slot 251 has a vent 252 that extends along a first direction and can communicate with the second air passage 241. The shape of the slot 251 is adapted to the aerosol generating rod 500. The end of the aerosol generating rod 500 that extends into the receiving cavity 21 can be inserted into the slot 251 to support and fix the aerosol. When the aerosol generating rod 500 is suctioned, the gas in the airflow passage can pass through the vent 252 on the support base 25 into the slot 251 and be drawn into the aerosol generating rod 500.
[0049] By providing an independent second air passage 241 inside the side wall of the heat insulation sleeve 24, the second air passage 241 is isolated from the receiving cavity 21 of the heat insulation sleeve 24. When the airflow passes through the second air passage 241, it is isolated from the heating element 3 in the receiving cavity 21, thereby greatly reducing heat loss, which is beneficial to saving energy and improving heating efficiency.
[0050] It should be noted that in practical applications, the second air passage 241 can extend directly to the outer end of the vent 252, or it can maintain a certain distance from the vent 252. In addition, the number of vents 252 on the support base 25 can be one or more, and the diameter of the vent 252 can be set according to the usage requirements. When there are multiple vents 252, the multiple vents 252 can be arranged in an array, such as a ring array, a matrix, or other regular array forms, so that the airflow can enter the interior of the aerosol generating rod 500 more evenly.
[0051] In a specific example, such as Figure 7 , Figure 9 In the example, the inner wall of the slot 251 may be provided with protrusions extending in the first direction as needed, and multiple protrusions may be provided in the circumferential direction of the slot 251, so that when the aerosol generating rod 500 is inserted into the slot 251, the protrusions abut against the aerosol generating rod 500 and exert a certain amount of pressure on the aerosol generating rod 500 so that the aerosol generating rod 500 remains fixed.
[0052] Furthermore, such as Figures 3 to 5 as well as Figure 11 , Figure 12 As shown, in the first sealing member 23, a first side opening 2321 is provided on the inner side wall of the first air passage 232. In the first direction, the first side opening 2321 is located on the side wall of the first air passage 232 away from the air inlet 12, and in the second direction, the first side opening 2321 is located on the side of the first air passage 232 away from the through hole 231. The second air passage 241 of the heat insulation sleeve 24 is opposite to the first side opening 2321 in the first direction and communicates with the first side opening 2321 so that the airflow in the first air passage 232 can pass through the first side opening 2321 and enter the second air passage 241.
[0053] In this embodiment, a first side opening 2321 is provided to adapt to the position of the misaligned first airway 232 and second airway 241, such as... Figure 4In the example, in the second direction, the second air passage 241 is located outside the first air passage 232. When the airflow passes through the first side opening 2321, it will undergo a certain change of direction and then enter the second air passage 241. Of course, in practical applications, the position of the first side opening 2321 can be adjusted according to the relative position of the second air passage 241 and the first air passage 232. Alternatively, when the first air passage 232 and the second air passage 241 are correspondingly set in the first direction, the first side opening 2321 can be omitted, and the first air passage 232 can be directly connected to the second air passage 241. The specific configuration can be determined according to the actual situation.
[0054] Furthermore, in a specific example, such as Figure 4 , Figure 5 as well as Figures 7 to 13 As shown, in the heat insulation sleeve 24, a first abutting structure 242 is provided on the inner wall of the receiving cavity 21 facing the first sealing member 23, and the first abutting structure 242 is arranged along the circumference of the heat insulation sleeve 24; correspondingly, a second abutting structure 253 is provided on the inner wall of the slot 251 of the support base 25 facing the first sealing member 23, and the second abutting structure 253 is arranged along the circumference of the slot 251, and in the first direction, the second abutting structure 253 is arranged opposite to the first abutting structure 242. The heating element 3 specifically includes a heating tube 31, which is arranged in the receiving cavity 21 along the first direction. One end of the heating tube 31 abuts against the first abutting structure 242, and the other end extends into the slot 251 and abuts against the second abutting structure 253, so that the heating tube 31 is clamped from both ends by the first abutting structure 242 and the second abutting structure 253, so that the heating tube 31 is kept fixed. When the aerosol generating rod 500 is inserted into the receiving cavity 21, it can pass through the heating tube 31 and be inserted into the slot 251. The heating tube 31 can heat the aerosol generating rod 500 in the circumferential direction, so that the aerosol generating rod 500 is heated more evenly.
[0055] Specifically, such as Figure 4 In the example, the first abutment structure 242 and the second abutment structure 253 can adopt an annular stepped structure to adapt to the shape of the heating tube 31; of course, the first abutment structure 242 and / or the second abutment structure 253 can also be set as circumferentially spaced protrusion structures according to actual needs, so as to abut the end of the heating tube 31, and also to fix and support the heating tube 31.
[0056] It should be noted that the specific form of the heating element 3 is not limited to the heating tube 31 in the above embodiments. It can also be a heating plate, heating mesh or other structural forms suitable for heating aerosol generating rods, as needed.
[0057] Furthermore, such as Figure 4 , Figure 7 , Figure 8 In the example, the support assembly 2 also includes a second seal 26. The second seal 26 is sealed to the end of the heat insulation sleeve 24 away from the insertion port 11 to seal the receiving cavity 21 and the second air passage 241. There is a certain space between the second seal 26 and the support base 25, forming an air guide cavity 27. A second side opening 261 is provided on the side wall of the air guide cavity 27, and the second side opening 261 communicates with the second air passage 241 so that the second air passage 241 communicates with the air guide cavity 27 through the second side opening 261, and forms a relatively closed airflow space. The airflow in the second air passage 241 can be turned through the second side opening 261 and enter the air guide cavity 27, and then pass through the air guide cavity 27 through the vent hole 252 on the support base 25 into the interior of the aerosol generating rod 500 in the slot 251.
[0058] Furthermore, in a specific example, such as Figure 3 , Figure 4 and Figure 8 As shown, the second airway 241 is specifically an annular airway, meaning that the second airway 241 is arranged around the receiving cavity 21. In the circumferential direction, the first side opening 2321 and the second side opening 261 are spaced apart, meaning that in the first direction, the first side opening 2321 and the second side opening 261 are slightly misaligned. After the airflow enters the second airway 241 through the first side opening 2321, it needs to move along the first direction while simultaneously moving a certain distance circumferentially, forming a spiral motion, and then enters the air guide cavity 27 through the second side opening 261. Preferably, as... Figure 4 In the example shown, the second side opening 261 and the first side opening 2321 are 180° apart in the circumferential direction, so that after the airflow enters the second air passage 241, it needs to go around to the other side of the receiving cavity 21 before it can enter the air guide cavity 27 through the second side opening 261. Specifically, the end of the second air passage 241 away from the first seal 23 can be designed as follows: Figure 8 The open structure shown in the figure seals the end of the second air passage 241 with the second sealing member 26, thus forming a form where one end of the second air passage 241 is closed and the other end is open, which facilitates processing and manufacturing. In addition, in practical applications, multiple second side openings 261 can be provided as needed.
[0059] In one specific implementation, such as Figures 3 to 5 As shown, in the first direction, the end of the heat insulation sleeve 24 facing the insertion port 11 is provided with a first mounting groove 243, at least a portion of the first sealing member 23 is disposed in the first mounting groove 243, and the first sealing member 23 is sealed and engaged with the inner sidewall of the first mounting groove 243 to form a sealed connection with the heat insulation sleeve 24, and to support and fix the first sealing member 23.
[0060] In one specific implementation, such as Figures 3 to 5As shown, in the first direction, the second sealing member 26 is provided with a second mounting groove 262 at one end facing the insertion port 11, and the end of the heat insulation sleeve 24 away from the insertion port 11 extends into the second mounting groove 262 and seals with the inner wall of the second mounting groove 262 to achieve a sealed connection with the second sealing member 26.
[0061] It should be noted that both the first sealing element 23 and the second sealing element 26 mentioned above can be made of silicone material to improve the assembly sealing performance and provide a buffering effect.
[0062] In further embodiments of this application, such as Figure 1 , Figure 3 and Figure 14 As shown, the atomizing device 100 also includes a power supply component 42. The power supply component 42 is disposed inside the housing 1 and is electrically connected to the heating element 3 to supply power to the heating element 3, enabling the heating element 3 to generate heat when energized. When the aerosol generating rod 500 passes through the insertion port 11 and enters the receiving cavity 21 along the first direction, the heating element 3 is energized and generates heat to heat the aerosol generating rod 500.
[0063] The following describes a specific example of the atomizing device 100 of this application with reference to the accompanying drawings.
[0064] like Figures 1 to 14 As shown, the atomizing device 100 is specifically a heat-not-burn atomizing device. The height direction is the first direction, the width direction is the second direction, and the thickness direction is the third direction. The top of the housing 1 has an insertion port 11 and an air inlet 12, which are spaced apart in the second direction.

The air inlet 12 has an arc-shaped strip structure in cross-section. Multiple small-diameter silencing holes 1311 are formed on the thin sheet structure 131 opposite to the air inlet 12, arranged in two rows of arc-shaped arrays. The diameter of each silencing hole 1311 is smaller than the diameter of the air inlet 12, and on a projection plane perpendicular to the first direction, all the silencing holes 1311 are located within the projection range of the air inlet 12.

[0065] like Figures 3 to 5 as well as Figure 14As shown, a support structure 43 is provided inside the housing 1, and the support structure 43 divides the internal space of the housing 1 into different chambers. The support assembly 2 includes a first seal 23, a heat insulation sleeve 24, a support base 25, and a second seal 26, which are arranged sequentially in a first direction. The bottom of the second seal 26 is connected to the support structure 43, and the bottom of the heat insulation sleeve 24 is inserted into the second mounting groove 262 of the second seal 26, and is sealed with the inner sidewall of the second mounting groove 262. The top of the heat insulation sleeve 24 has a first mounting groove 243, a portion of the first seal 23 is disposed in the first mounting groove 243, and is sealed with the inner sidewall of the first mounting groove 243. The top of the first seal 23 abuts against the top wall of the housing 1. The first sealing element 23 is specifically an annular silicone structure with a through hole 231 corresponding to the insertion port 11. Multiple flexible contact structures 2311 are arranged circumferentially on the inner sidewall of the through hole 231 for abutting against the sidewall of the aerosol generating rod 500. The first sealing element 23 is also provided with a first air passage 232 corresponding to the air inlet 12. The first air passage 232 extends along a first direction, and a first side opening 2321 is provided on the sidewall of the first air passage 232 away from the through hole 231. The heat insulation sleeve 24 has a receiving cavity 21, which corresponds to the through hole 231. The inner wall of the receiving cavity 21 facing the through hole 231 has an annular first abutment structure 242. The end of the first abutment structure 242 away from the insertion port 11 along the first direction has a stepped structure. The end of the first abutment structure 242 facing the insertion port has a positioning protrusion 244, which engages with a corresponding positioning hole on the end face of the first sealing member 23 for easy assembly. The side wall of the heat insulation sleeve 24 has... A second air passage 241 surrounds the receiving cavity 21 and is isolated from the receiving cavity 21. The top of the second air passage 241 is connected to the first side opening 2321 to form an air intake passage 22. The bottom of the second air passage 241 is an open structure and is sealed to the bottom wall of the second mounting groove 262. The second side opening 261 is provided on the inner side wall of the second mounting groove 262 near the bottom wall of the groove, and the second side opening 261 is 180° away from the first side opening 2321 in the circumferential direction. The support base 25 is disposed in the second mounting groove 262 and is correspondingly disposed at the end of the heat insulation sleeve 24 away from the insertion port 11; part of the support base 25 extends into the heat insulation sleeve 24 and forms a slot 251. An annular second abutment structure 253 is formed on the inner side wall of the slot 251, and the second abutment structure 253 is specifically in the form of a stepped structure; a plurality of vent holes 252 extending along the first direction are provided on the bottom wall of the slot 251; an air guide cavity 27 is formed between the bottom of the support base 25 and the bottom wall of the second mounting groove 262, and the air guide cavity 27 is connected to the second side opening 261 and the vent holes 252.The heating element 3 specifically adopts the structure of a heating tube 31. The heating tube 31 is arranged in the receiving cavity 21 along the first direction. One end of the heating tube 31 abuts against the first abutting structure 242, and the other end extends into the slot 251 and abuts against the second abutting structure 253. The outer wall of the heating tube 31 has a heating resistor and a lead structure 311. The lead structure 311 extends outward through the wire groove 254 on the outside of the support base 25 and the second sealing member 26.
[0066] like Figure 14 In the example, the bottom of the second seal 26 has a sensor mounting groove, in which an airflow sensor 41 is sealed and installed. Correspondingly, the bottom wall of the second mounting groove 262 has a flexible diaphragm 263. The upper part of the flexible diaphragm 263 is an air guiding cavity 27, and the lower part is a sensing cavity mounting groove. The flexible diaphragm 263 can deform and move under air pressure. The airflow sensor 41 is used to sense changes in air pressure in the sensor mounting groove and can generate a corresponding sensing signal. The power supply assembly 42 is located in another chamber inside the housing 1, including a battery 421 and an electronic control board 422 that are electrically connected. The electronic control board 422 is provided with a control circuit and is electrically connected to the airflow sensor 41 and the pin structure 311 of the heating tube 31. The power supply state of the battery 421 to the heating tube 31 is controlled by the electronic control board 422.
[0067] When using, such as Figures 3 to 5In the example, the aerosol generating rod 500 can be inserted through the insertion port 11 and through the heating tube 31 into the slot 251 of the support base 25. The inner sidewall of the slot 251 also has a plurality of rigid protruding ridge structures to abut and fix with the sidewall of the aerosol generating rod 500. At the same time, the flexible contact structure 2311 on the inner sidewall of the through hole 231 of the first sealing member 23 abuts and fixes with the sidewall of the aerosol generating rod 500. When the user performs a suction action on the aerosol generating rod 500, the gas in the air guiding chamber 27 is drawn into the aerosol generating rod 500, creating a negative pressure in the air guiding chamber 27. Under the action of the negative pressure, the flexible diaphragm 263 deforms and moves towards the air guiding chamber 27, causing a change in the air pressure in the sensor mounting slot. This causes the airflow sensor 41 to sense and generate a sensing signal. The electronic control board 422 controls the battery 421 to supply power to the heating element 3 based on the sensing signal, so that the heating tube 31 heats up to heat the aerosol generating rod 500. At the same time, external air passes through the thin sheet. Multiple silencers 1311 on structure 131 enter the air inlet 12, and the airflow then enters the first air passage 232, then passes through the first side opening 2321 into the second air passage 241. The airflow flows in the second air passage 241 along the first direction and also along the circumference, and enters the air guide cavity 27 through the second side opening 261. Finally, it passes through the vent 252 into the slot 251 and is sucked into the aerosol generating rod 500. The airflow mixes with the aerosol generated inside the aerosol generating rod 500 and flows to the suction end of the aerosol generating rod 500.
[0068] In this embodiment, the atomizing device 100 utilizes a thin sheet structure 131 with a very small thickness to create a sound-absorbing hole 1311 that connects to the air inlet 12. This makes the sound-absorbing hole 1311 the narrowest point in the overall airway, reducing airflow noise by using the principle of small hole sound absorption, thereby preventing noise during the suction process. At the same time, by setting an independent air inlet channel 22, the airflow path is isolated from the receiving cavity 21 where the heating element 3 is located, which can enhance the heat insulation effect, reduce heat loss, and make the airflow smoother, thus improving the user experience.
[0069] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
