Description

Technical Field

[0001] This application relates to the field of aerosol generating device technology, and more specifically, to a microphone assembly and an aerosol generating device. Background Technology

[0002] Aerosol generating devices typically contain a microphone assembly and an atomizing core assembly. The microphone assembly is usually used to sense the inhalation action. When the user inhales, the microphone assembly detects the current state through airflow sensing, electromagnetic induction, deformation sensing, etc., and controls the atomizing core assembly to enter the heating state to heat the aerosol generating medium and generate aerosol for the user to inhale.

[0003] When the aerosol generating device is drawing in air, some of the gas will carry external mist or aerosol back into the aerosol generating medium. Then, the mist or aerosol in this part of the gas will condense into liquid. The liquid may flow into the microphone, which may lead to a decrease in microphone sensitivity or even failure. Alternatively, if the aerosol generating medium inside the aerosol generating device has not been used for a long time, it may also corrode the microphone along the nozzle inside the aerosol generating device, which may lead to a short service life and poor performance of the microphone. Utility Model Content

[0004] The technical problem to be solved by this application is the short service life and poor performance of the microphone components in existing aerosol generating devices.

[0016] Furthermore, the aerosol generating device includes a first sub-body and a second sub-body connected to each other. The first sub-body is provided with a suction channel, an atomizing core assembly, a mouthpiece, a microphone, and a first air tube. The mouthpiece passes through the first sub-body and is connected to the interior of the atomizing core assembly.

[0017] The second sub-body is provided with the microphone assembly, one end of the first air tube is connected to the microphone, and the other end is connected to the second through hole to connect the microphone and the suction channel.

[0018] Furthermore, the second seal includes a protrusion that protrudes away from the first seal. The second through hole is disposed on the protrusion and includes a first sub-through hole and a second sub-through hole. The first sub-through hole connects the receiving cavity and the second sub-through hole.

The first sub-air inlet is connected to the first air tube. At least a portion of the second sealing member passes through the second sub-air inlet, and the second sealing member is provided with a second sub-through hole. The second sub-through hole connects the microphone and the first air tube.

Furthermore, whenever a numerical range is referred to herein, it means including any referenced number (fraction or integer) within the referred range.

[0044] Please refer to Figures 1-3This application provides a microphone assembly 100, comprising:

[0045] Microphone 10;

[0046] The first sealing element 110 is provided with a first receiving groove and a first through hole 111, and the microphone 10 is located in the first receiving groove;

[0047] The second sealing member 120 is provided with a second receiving groove 123 and a second through hole 121. The first sealing member 110 is located in the second receiving groove 123. The first sealing member 110 and the second receiving groove 123 define a receiving cavity. Along the depth direction of the first through hole 111 (Z direction in the figure), the orthographic projections of the first through hole 111 and the second through hole 121 are misaligned.

[0048] In this embodiment, firstly, the microphone 10 passes through the gas passage formed by the first through hole 111, the receiving cavity, and the second through hole 121, so that when the user inhales, the gas can travel along... Figure 1 The liquid flows through the microphone 10 in the direction of the middle arrow, thereby activating the aerosol generating device containing the microphone assembly 100. Secondly, the first seal 110 can effectively accommodate and restrict the movement of the microphone 10, while the second seal 120 can accommodate and restrict the first seal 110, thus the microphone assembly 100 has high stability. Then, along the Z direction in the figure, the orthographic projections of the first through hole 111 and the second through hole 121 are misaligned. Therefore, when external liquid passes through the second through hole 121, it cannot drip directly into the first through hole 111, thereby preventing liquid from directly passing through the first through hole 111 and contacting the microphone 10, thus improving the service life of the microphone assembly 100.

[0049] In summary, the microphone assembly 100 of this application embodiment has strong stability, long service life, and good performance.

[0050] Further, please refer to Figures 1-3 The first sealing element 110 is provided with a slope 113. Along the depth direction of the first through hole 111 (Z direction in the figure), the orthographic projection of the second through hole 121 is located on the slope 113. One end of the slope 113 is connected to the side of the first through hole 111 away from the microphone 10, and along the direction away from the first through hole 111 (X direction in the figure), the vertical distance between the slope 113 and the second through hole 121 gradually increases.

[0051] In this embodiment, along the Z direction in the figure, the orthographic projection of the second through hole 121 is located on the inclined surface 113. Therefore, when liquid flows into the receiving cavity from the second through hole 121, the liquid will move along the inclined direction of the inclined surface 113. Along the direction away from the first through hole 111, the vertical distance between the inclined surface 113 and the second through hole 121 gradually increases. Therefore, when liquid falls onto the inclined surface 113, it will move away from the first through hole 111, thus effectively preventing liquid from entering the first through hole 111 and contacting the microphone 10. In summary, the microphone 10 of this embodiment has a long service life and good performance.

[0052] Further, please refer to Figure 2 The microphone assembly 100 also includes a first liquid-absorbing element 200, and the first sealing element 110 is also provided with a third receiving groove 114, the opening of the third receiving groove 114 being connected to the end of the inclined surface 113 away from the first through hole 111.

[0053] In this embodiment, the opening of the third receiving groove 114 is connected to the end of the inclined surface 113 away from the first through hole 111. Therefore, when liquid drips onto the inclined surface 113, it will flow along the inclined surface 113 to the third receiving groove 114 and finally contact the first liquid suction member 200 in the third receiving groove 114. The first liquid suction member 200 will store and absorb the liquid to prevent the liquid from flowing back to the microphone 10 when the user shakes the microphone assembly 100 (when the user shakes the aerosol generating device).

[0054] It should be understood that the first absorbent element 200 can be an oil-absorbing cotton.

[0055] Further, please refer to Figures 2-5 The second seal 120 includes a protrusion 122 that protrudes away from the first seal 110. A second through hole 121 is disposed on the protrusion 122 and includes a first sub-through hole 1211 and a second sub-through hole 1212. The first sub-through hole 1211 connects to the receiving cavity and the second sub-through hole 1212. The second sub-through hole 1212 is disposed on the side wall of the protrusion 122 and connects to the external environment.

[0056] It should be understood that the depth direction (X-axis direction) of the second sub-through hole 1212 can be oriented away from the first air pipe 34. In this case, when the aerosol or other airflow in the first air pipe 34 flows to the protrusion 122, it cannot directly pass through the second sub-through hole 1212. Instead, it first contacts the second sub-air inlet 33 and the outer wall of the protrusion 122, and then condenses to form liquid. This liquid will remain between the second sub-air inlet 33 and the second seal 120. Therefore, with the depth direction of the second sub-through hole 1212 oriented away from the first air pipe 34 in this embodiment, it can effectively prevent externally flowing gas from entering the protrusion 122, thereby preventing this gas or liquid from contacting the microphone 10 and improving the service life of the microphone 10.

[0057] In this embodiment, the protrusion 122 prevents external liquid from dripping onto the upper surface (Z-axis direction) of the second seal 120 and directly flowing into the second through hole 121. Because the second sub-through hole 1212 is located on the sidewall of the protrusion 122, and the first sub-through hole 1211 connects the receiving cavity and the second sub-through hole 1212, the second through hole 121 has an overall inverted "L" shape. When the protrusion 122 is inserted into a structure such as a cigarette cartridge, the liquid, under the influence of gravity, falls along the Z-axis towards the location of the second through hole 121. At this time, because the second sub-through hole 1212 is located on the sidewall of the protrusion 122, it prevents the liquid from directly entering the second through hole 121, thereby preventing the microphone 10 from being corroded by the liquid.

[0058] It should be understood that the second sub-through hole 1212 can be perpendicular to the first sub-through hole 1211 to form a hole extending along the X-axis direction in the figure.

[0059] Further, please refer to Figure 5 The protrusion 122 includes an annular protrusion 1222 and a cap 1221. A first sub-through hole 1211 and a second sub-through hole 1212 are disposed in the cap 1221. The cap 1221 is detachably inserted into the protrusion 122.

[0060] In this embodiment, the cap 1221 can be inserted into the annular protrusion 1222 from top to bottom along the Z direction in the figure, from the Z axis, to complete the assembly of the cap 1221 and the annular protrusion 1222. Therefore, the assembly efficiency of the protrusion 122 in this embodiment is high. At the same time, during disassembly, the cap 1221 can be quickly disassembled through the second through hole 121 as a gripping position. Therefore, different models of caps 1221 can be efficiently replaced to adapt to different ventilation requirements.

[0061] Further, please refer to Figure 2 The first receiving groove includes a first sub-receiving groove and a second sub-receiving groove 112. The first sub-receiving groove is disposed at the bottom of the second sub-receiving groove 112. The first through hole 111 communicates with the first sub-receiving groove. The microphone 10 is located in the second sub-receiving groove 112 and is interference-fitted with the second sub-receiving groove 112.

[0062] In this embodiment, the interference fit between the microphone 10 and the second sub-receiving groove 112 can prevent the microphone 10 from shifting position during operation. The first sub-receiving groove allows the gas to still have a large flow channel after passing through the first through hole 111, thereby allowing the microphone 10 to contact a larger volume of gas and improve the accuracy of the microphone 10.

[0063] Accordingly, please refer to Figures 1-5 This application also provides an aerosol generating device, which includes the microphone assembly 100 of any of the above embodiments.

[0064] In this embodiment, since the aerosol generating device includes the microphone assembly 100 of any of the above embodiments, the aerosol generating device has high stability and can prevent liquid from directly passing through the first through hole 111 and contacting the microphone 10, thereby improving the service life of the aerosol generating device.

[0065] Further, please refer to Figures 1-5 The aerosol generating device includes a first sub-body 30 and a second sub-body 40 connected to each other. The first sub-body 30 is provided with a suction channel, an atomizing core assembly 22, a mouthpiece 21, a microphone 10 and a first air tube 34. The mouthpiece 21 passes through the first sub-body 30 and is connected to the inside of the atomizing core assembly 22. The suction channel passes through the mouthpiece 21 and the atomizing core assembly 22 and is connected to the external environment.

[0066] The second sub-body 40 is provided with a microphone assembly 100. One end of the first air tube 34 is connected to the microphone 10, and the other end is connected to the second through hole 121 to connect the microphone 10 and the suction channel.

[0067] In this embodiment, after the first sub-body 30 and the second sub-body 40 are connected, the first air tube 34 can connect the second through hole 121 and the suction channel, so that when the user inhales the nozzle 21 of the aerosol generating device, the airflow will follow the... Figure 1 The air flows through the microphone 10 in the direction of its movement, and then flows out of the aerosol generating device through the suction channel, thereby activating the microphone 10.

[0068] Further, please refer to Figures 4-7 An air inlet 31 is provided at the end of the first sub-body 30 away from the mouthpiece 21. An elastic ring 124 is provided on the side of the second sealing member 120 facing the first sub-body 30. The elastic ring 124 abuts against the first sub-body 30. Along the direction from the first sub-body 30 to the second sub-body 40, the orthographic projection of the air inlet 31 is located within the orthographic projection range of the elastic ring 124, which is used to connect the first air tube 34 and the microphone 10.

[0069] In this embodiment, after the first sub-body 30 and the second sub-body 40 are connected, the elastic ring 124 can seal the air inlet 31 to prevent external airflow from entering the air inlet 31 or the second through hole 121 through the gap between the first sub-body 30 and the second sub-body 40, and also to prevent external liquid from entering the air inlet 31 or the second through hole 121, thereby improving the performance and service life of the aerosol generating device. It should be understood that the microphone assembly may also include a second liquid-absorbing element (not shown in the figure), which is located between the elastic ring 124 and the first sub-body 30. In this case, the second liquid-absorbing element can absorb liquid from the first sub-body 30, thereby preventing liquid from accumulating on the surface of the second seal 500 and flowing to the microphone 10.

[0070] It should be understood that the protrusion 122 can be inserted into the air inlet 31. It should also be understood that the protrusion 122 can be a separate component, in which case the protrusion 122 and the second seal 120 are connected by assembly, thus allowing the user to quickly replace the protrusion 122, improving the maintenance efficiency of the air passage structure. Alternatively, the protrusion 122 can be integrally formed with the second seal 120, in which case the connection between the protrusion 122 and the second seal 120 is reliable and has higher strength.

[0071] For further details, please refer to... Figure 5 The air inlet 31 includes a first sub-air inlet 32 ​​and a second sub-air inlet 33. Along the direction from the first sub-body 30 to the second sub-body 40, the orthographic projections of the first sub-air inlet 32 ​​and the second sub-air inlet 33 are separate, and the depth of the first sub-air inlet 32 ​​is less than that of the second sub-air inlet 33. The first sub-air inlet 32 ​​is connected to the first air pipe 34. The protrusion 122 passes through the second sub-air inlet 33, and the distance between the second sub-through hole 1212 and the opening of the second sub-air inlet 33 is a first distance, which is greater than the depth of the first sub-air inlet 32.

[0072] In this embodiment, the orthographic projections of the first sub-inlet 32 ​​and the second sub-inlet 33 are separate. Therefore, when liquid enters the first air pipe 34 and drips along it, it cannot directly contact and drip into the second sub-inlet 33. Simultaneously, because the first distance is greater than the depth of the first sub-inlet 32 ​​(in the Z direction of the figure), even if liquid enters the inlet 31, it must first submerge the first sub-inlet 32 ​​and then accumulate to the height of the second through-hole 121 before entering it. The lower ends of the first sub-inlet 32 ​​and the second sub-inlet 33 serve to store liquid and prevent it from directly entering the second through-hole 121. Therefore, the aerosol generating device of this embodiment can further prevent the microphone 10 from being corroded by liquid.

[0073] Further, please refer to Figures 8-10 The aerosol generating device also includes a PCB board 330, a button decoration 320, and a button bracket 310. The button bracket 310 abuts against the PCB board 330 and is provided with a button groove 311 and a snap-fit ​​groove 312. The button decoration 320 is located in the button groove 311. The snap-fit ​​groove 312 is provided at the connection between the bottom wall and the side wall of the button groove 311. The side wall of the button decoration 320 is provided with a snap-fit ​​321, which abuts against the snap-fit ​​groove 312.

[0074] In this embodiment, the engagement of the buckle 321 and the buckle groove 312 can prevent the button decoration 320 from falling off into the button groove 311. At the same time, the combination of the button decoration 320 and the button bracket 310 can facilitate the user to replace different button decorations 320.

[0075] Further, please refer to Figures 11-12 The aerosol generating device also includes a housing 400, a second sub-body disposed within the housing 400, a battery 380 and a PCB board 330 disposed within the housing 400, a positioning groove 410 disposed on the side wall of the housing 400, a contact surface disposed at the bottom of the button bracket 310, the button bracket 310 being disposed within the positioning groove 410, and at least a portion of the button bracket 310 passing through the bottom of the positioning groove 410 and exposed to the external environment; the contact surface abuts against the side wall of the positioning groove 410.

[0076] In this embodiment, the contact surface abuts against the side wall of the positioning groove 410, thus preventing the button bracket 310 from rotating around the center of the positioning groove 410, thereby improving the structural stability of the aerosol generating device.

[0077] It should be understood that, please refer to Figure 10 The aerosol generating device may further include a charging plate 340, LEDs, a light guide column 360, a light-guiding silicone 370, and an oil bottle, all stacked sequentially within the housing 400. In this case, the charging plate 340 can be connected to the PCB board 330 for charging and discharging control. The LED 350 emits light of different colors or frequencies to alert the user to the current operating status of the aerosol generating device. The light guide column 360 guides the light along a preset path for easy observation by the user. The light-guiding silicone 370 guides the light while preventing the light guide column 360 from hitting the oil bottle and also prevents external liquids from entering the LED 350. A battery 380 can be connected to the PCB board, charging plate, LEDs, and other structures to provide energy.
