Description

Technical Field

[0002] An aerosol generating device is an apparatus that can generate aerosol for the user to inhale.

[0003] Currently, the microphone and atomizer assembly of an aerosol generating device are assembled in the same air flow channel. When a user uses the aerosol generating device to inhale, air flows in the air flow channel. The flowing airflow causes the air flow channel to be in a negative pressure state, triggering the microphone, and then controlling the activation of the atomizer assembly, so that the atomizer assembly generates aerosol for the user to inhale.

[0004] However, based on the working principle of the microphone, the air flow rate in the airflow channel must reach or exceed a flow rate threshold to trigger the microphone. For example, the microphone may not be triggered when the user takes a light puff. In other words, the triggering sensitivity of the microphone of the existing aerosol generating device is poor, which affects the user experience. Utility Model Content

[0053] like Figures 1 to 7As shown, the aerosol generating device of the embodiment of the present application includes a housing 10, an atomizer assembly 20 and a circuit board 30. The housing 10 is formed with a mouthpiece 13, a first air channel 11 and a second air channel 12. The first air channel 11 and the second air channel 12 are independent of each other, that is, the airflow in the first air channel 11 and the airflow in the second air channel 12 will not flow into each other. The first end of the first air channel 11 and the first end of the second air channel 12 are both connected to the mouthpiece 13. The user performs an inhalation (inhalation) action through the mouthpiece 13, so that the air in the first air channel 11 and the second air channel 12 flows. The atomizer assembly 20 is installed in the housing 10. The atomizer assembly 20 has a first connecting end 21 and a second connecting end 22. The first connecting end 21 of the atomizer assembly 20 is connected and connected to the second end of the first air channel 11. When the user performs an inhalation action, the air flows along the path direction from the atomizer assembly 20 to the first air channel 11. The flowing air carries the aerosol generated by the atomizer assembly 20 to the mouthpiece 13 for the user to inhale. The circuit board 30 is mounted within the housing 10 and includes a microphone 31 and an electrode terminal 32. The second end of the second airway 12 is connected to the microphone 31. When a user inhales, air in the second airway 12 flows and is easily emptied, creating a near-vacuum negative pressure in the second airway 12. This quickly and stably triggers the microphone 31. The electrode terminal 32 is electrically connected to the second connection end 22 of the atomizer assembly 20. The triggered microphone 31 activates the atomizer assembly 20, generating aerosol.

[0054] When a user uses the aerosol generating device provided by the present application for inhalation, the user performs an inhalation (inhalation) action through the mouthpiece 13, causing the air in the first airway 11 and the second airway 12 to flow, and the air in the second airway 12 is easily inhaled by the user, so that the second airway 12 is in a negative pressure state close to vacuum to trigger the microphone 31, and then the triggered microphone 31 controls the atomization component 20 to start and generate aerosol. The aerosol generated by the atomization component 20 is carried by the air flowing in the first airway 11 and flows toward the mouthpiece 13 for inhalation by the user. Compared with the existing aerosol generating devices, the first air duct 11 and the second air duct 12 in the aerosol generating device of the present application are independent of each other. When the user performs the inhalation action, the airflow in the first air duct 11 and the airflow in the second air duct 12 will not flow into each other. Moreover, no matter whether the user performs a light inhalation action or a deep inhalation action, the air in the second air duct 12 can be easily sucked out, so that the second air duct 12 is in a negative pressure state close to vacuum, thereby quickly and stably triggering the microphone 31, thereby significantly improving the sensitivity of the microphone 31 to be triggered, and greatly improving the user experience of using the aerosol generating device.

[0055] like Figure 2 、 Figure 4 、 Figures 6 to 9As shown, the aerosol generating device of the embodiment of the present application further includes a bracket 40 and a first plastic sheet 50. The bracket 40 is installed in the housing 10 and provides mounting support for the circuit board 30, that is, the circuit board 30 is installed on the bracket 40. In addition, the bracket 40 includes a horizontal frame 41, and the microphone 31 is located on one side of the horizontal frame 41. Furthermore, the horizontal frame 41 defines a first channel 411, which is connected to the microphone 31. The first plastic sheet 50 is installed on the side of the horizontal frame 41 facing away from the microphone 31. A transfer channel 51 is formed between the first plastic sheet 50 and the horizontal frame 41. The first plastic sheet 50 defines a second channel 52, which is connected to the transfer channel 51, and the second channel 52 is connected to the transfer channel 51. The second channel 52 is connected to the second end of the second air channel 12, so that the second air channel 12 is connected to the microphone 31 by sequentially connecting the second channel 52, the transfer channel 51, and the first channel 411. In this way, the second air channel 12 is fully independent of the first air channel 11. When the user performs the inhalation action, there is no cross-flow between the second air channel 12 and the first air channel 11. That is, the air in the second air channel 12 is sucked out by the user alone, so that the microphone 31 is triggered in a negative pressure environment that is close to a vacuum, with high triggering efficiency and low temperature, thereby improving the sensitivity of the triggering microphone 31.

[0056] like Figure 2 、 Figure 4 、 Figure 6 and Figure 7 As shown, the aerosol generating device of the embodiment of the present application further includes a first seal 60, which is disposed between the microphone 31 and the horizontal frame 41 to ensure a seal between the microphone 31 and the horizontal frame 41. The first seal 60 defines a third channel 61, through which the first channel 411 and the microphone 31 are connected. In other words, the second air channel 12 is connected to the microphone 31 by sequentially connecting the second channel 52, the transfer channel 51, the first channel 411, and the third channel 61. Because the first seal 60 seals the microphone 31 from the horizontal frame 41, when a user inhales, the air in the second air channel 12 is emptied and no air is replenished from the outside. This facilitates the formation of a near-vacuum negative pressure environment within the second air channel 12, allowing the microphone 31 to be triggered in this near-vacuum negative pressure environment, thereby improving the triggering sensitivity of the microphone 31.

[0057] Furthermore, the first rubber plate member 50 is an elastic rubber plate member, which can be a flexible rubber plate member made of silicone material. Figure 8As shown, a sealing wall 53 is provided on the side of the first rubber sheet member 50 facing away from the horizontal frame plate 41. The sealing wall 53 is elastically deformable. Furthermore, the first rubber sheet member 50 and the sealing wall 53 are integrally formed. The sealing wall 53 surrounds the second passage 52 and abuts against the end surface area of ​​the second end of the second air passage 12. The sealing wall 53 is squeezed by the end surface area of ​​the second end of the second air passage 12, causing elastic deformation, thereby sealing the first rubber sheet member 50 with the end surface area of ​​the second end of the second air passage 12. When the user is inhaling, since the first rubber sheet 50 is sealed from the end surface area of ​​the second end of the second air channel 12, during the process of the air in the second air channel 12 being sucked away, the air cannot be replenished into the second air channel 12 from between the first rubber sheet 50 and the end surface area of ​​the second end of the second air channel 12, so that the air in the second air channel 12 is easily sucked out, that is, the second air channel 12 is easily in a negative pressure state close to vacuum, thereby sensitively triggering the microphone 31.

[0058] like Figures 1 to 5 As shown, the housing 10 includes a first shell member 110 and a second shell member 120, and the first shell member 110 and the second shell member 120 are detachably connected. The aerosol generating device realizes a modular assembly method, which is simple and quick to assemble. In addition, the outer contours of the first shell member 110 and the outer contours of the second shell member 120 are both centrally symmetrical with respect to the central axis of the longitudinal direction of the aerosol generating device. The first shell member 110 forms a mouthpiece 13, a first air channel 11 and a second air channel 12. The atomizer assembly 20 is installed in the first shell member 110, and the first connecting end 21 of the atomizer assembly 20 is connected and communicated with the second end of the first air channel 11. The bracket 40 is installed in the second shell member 120, and the first rubber plate member 50 is provided with two second channels 52. One of the two second channels 52 is connected to and communicates with the second end of the second air channel 12. The second channel 52 that is not connected to the second end of the second air channel 12 is sealed with the outer wall of the first shell member 110. Since the outer contours of the first shell member 110 and the outer contours of the second shell member 120 are both centrally symmetrical with respect to the central axis of the longitudinal direction of the aerosol generating device, and the first rubber plate member 50 is provided with two second channels 52, therefore, when connecting the first shell member 110 and the second shell member 120, the first shell member 110 does not need to be fool-proofed aligned with the second shell member 120, and the first shell member 110 and the second shell member 120 can be connected by direct docking, and the second end of the second air channel 12 is also directly docked with and connected to one of the second channels 52, thereby simply and quickly realizing the connection between the second air channel 12 and the microphone 31, thereby improving assembly efficiency.

[0059] In the aerosol generating device of the embodiment of the present application, the first shell member 110 and the atomizing assembly 20 and other components assembled in the first shell member 110 form one module of the modular assembly. Specifically, Figure 2 、 Figure 4 、 Figure 6 and Figure 7 As shown, the first shell member 110 includes a first outer shell 111, an end shell 112, a second rubber sheet member 113, and a pipe member 114. The first outer shell 111 is formed with a first air channel 11, a first cavity 115 connected to the first air channel 11, and a second cavity 116 separated from the first cavity 115. The second rubber sheet member 113 is installed in the first outer shell 111, so that the first cavity 115 forms a liquid storage chamber and the second cavity 116 forms a first air inlet chamber. The second rubber sheet member 113 is provided with a first assembly channel 1131 and an air inlet channel 1133, and the air inlet channel 1133 is connected to the first air inlet chamber. The end shell 112 is sealed to the open end of the first outer shell 111. The end shell 112 and the second rubber sheet member 113 are separated to form a second air inlet chamber 117, and the second air inlet chamber 117 is connected to the air inlet channel 1133. The end shell 112 is provided with a second assembly channel 1121 and a third assembly channel 1122. The atomizer assembly 20 is disposed in the first cavity 115. The second connection end 22 of the atomizer assembly 20 passes through the first assembly channel 1131 and the second assembly channel 1121 in sequence. The atomizer assembly 20 is provided with an air inlet 23 and a liquid inlet 24. The air inlet 23 is connected to the second air inlet chamber 117, and the liquid inlet 24 is connected to the liquid storage chamber. The pipe 114 is disposed in the second cavity 116 to form the second air channel 12. The first end of the pipe 114 is sealed and inserted into the third assembly channel 1122 and connected to the second channel 52. The second end of the pipe 114 is connected to the mouthpiece 13. In addition, the second shell member 120 and the bracket 40, the first rubber plate member 50, the circuit board 30 and other components assembled in the second shell member 120 form another module of the modular assembly. In this way, the module formed by the first shell member 110 and the module formed by the second shell member 120 can be assembled separately in a modular manner. After the two modules are assembled, the two modules are docked to complete the final assembly step of the aerosol generating device, greatly improving the assembly efficiency.

[0060] like Figure 2 and Figure 4 As shown, the aerosol generating device of the embodiment of the present application further includes a first sealing ring 93 and a second sealing ring 94. When the second connecting end 22 of the atomizing assembly 20 passes through the first assembly channel 1131 and the second assembly channel 1121 in sequence, the first sealing ring 93 is arranged between the outer wall of the first connecting end 21 and the inner wall of the first air channel 11, and as shown in FIG. Figure 10 and Figure 11As shown, the inner wall of the first assembly channel 1131 is formed with a circumferential protrusion 1132, which abuts against the outer wall of the atomizer assembly 20 to achieve a seal, thereby preventing the liquid aerosol-generating substrate stored in the liquid storage chamber from leaking along the outer wall of the atomizer assembly 20. Furthermore, a second sealing ring 94 is provided between the outer wall of the second connecting end 22 of the atomizer assembly 20 and the inner wall of the second assembly channel 1121, thereby preventing air leakage from the second air inlet chamber 117 between the second connecting end 22 of the atomizer assembly 20 and the second assembly channel 1121.

[0061] When the user carries the aerosol generating device, if the aerosol generating device is shaken, shaken, or vibrated, the liquid aerosol generating substrate stored in the liquid storage chamber may flow into the second air inlet chamber 117 along the liquid inlet, air flow channel, and air inlet of the atomizing assembly 20, thereby causing the liquid aerosol generating substrate to leak to the outside. In order to prevent the liquid aerosol generating substrate from leaking to the outside, Figure 2 、 Figure 4 、 Figure 6 and Figure 7 As shown, the aerosol generating device of this embodiment of the present application further includes a liquid-absorbing cotton 70, which is mounted on the end housing 112 and located within the second air inlet chamber 117. The liquid-absorbing cotton 70 is spaced apart from the second rubber plate 113. As such, liquid aerosol-generating substrate flowing into the second air inlet chamber 117 is absorbed by the liquid-absorbing cotton 70, preventing further leakage of the liquid aerosol-generating substrate to the outside, thereby ensuring the cleanliness of the aerosol generating device.

[0062] like Figure 2 、 Figure 4 and Figure 7 As shown, the aerosol generating device of the embodiment of the present application further includes a first magnetic member 81 and a second magnetic member 82. The first magnetic member 81 is mounted on the end shell 112, and the second magnetic member 82 is mounted on the first rubber plate member 50. When the first shell member 110 and the second shell member 120 are docked, the first magnetic member 81 and the second magnetic member 82 are magnetically attracted to each other, so that the module formed by the first shell member 110 and the module formed by the second shell member 120 can be docked and assembled accurately and quickly, greatly improving assembly efficiency.

[0063] In the aerosol generating device of the embodiment of the present application, Figure 2 Figure 4 、 Figure 6 and Figure 7 As shown, the electrode terminal 32 is sequentially provided through the horizontal frame 41 and the first rubber plate 50. When the first shell member 110 and the second shell member 120 are connected, the electrode terminal 32 and the second connection end 22 of the atomizer assembly 20 abut against each other, thereby achieving electrical connection between the atomizer assembly 20 and the circuit board 30.

[0064] like Figure 2 、 Figure 4 、 Figure 6 and Figure 7 As shown, the aerosol generating device of the present embodiment further includes a first valve member 91. A first housing 111 defines an air valve 1111 communicating with the first air inlet chamber. The first valve member 91 is slidably mounted on the first housing 111 and positioned at the air valve 1111. When a user inhales, the first valve member 91 controls the opening of the air valve 1111, thereby controlling the amount of airflow along the airflow path from the air valve 1111, the first air inlet chamber, the second air inlet chamber 117, the air inlet 23, and the first airway 11.
