Description

Technical Field

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

[0002] Aerosol generators typically include an air inlet, an atomizing core, and a suction channel. The air inlet allows external gas to enter the aerosol generator. After entering, the gas flows through the atomizing core, then carries the aerosol generated by the heated core along the suction channel, ultimately allowing the user to inhale the aerosol. To prevent the air inlet from remaining open when the generator is not in use, thus allowing external dust and other substances to enter, a regulating switch is usually included to control the degree of opening of the air inlet.

[0003] In the existing technology, after the gas passes through the regulating switch and enters the air inlet, the airflow increases immediately due to the reduced flow area, resulting in a turbulent and dispersed form. Consequently, after the airflow passes through the air inlet and enters the suction channel, it will unevenly carry the aerosol to be drawn in by the user. At this time, the temperature and content of the aerosol drawn in by the user each time vary greatly, resulting in a poor user experience. Utility Model Content

[0004] The technical problem to be solved by the embodiments of this application is that the gas in the existing aerosol generating device is not drawn evenly, resulting in a poor taste of the aerosol inhaled by the user.

[0005] To solve the above-mentioned technical problems, the embodiments of this application adopt the following solutions:

[0012] The flow equalization component is integrally formed with the main body.

[0013] Furthermore, the air inlet includes a first sub-air inlet and a second sub-air inlet that are independently arranged. The regulating switch blocks the first sub-air inlet, the flow area of ​​the second sub-air inlet is smaller than that of the first sub-air inlet, and the flow equalization element is disposed in the first sub-air inlet.

[0014] Furthermore, the second sub-air inlet includes an air passage, an air outlet, and multiple air inlets. The multiple air inlets are connected to the same air passage and pass through the outer side wall of the main body. The air passage connects the air outlet and the air inlets, and the air outlet is connected to the suction channel.

[0015] Furthermore, the air inlet includes a first channel, a second channel, and a third channel. The first channel is disposed on the side wall of the main body and communicates with the external environment. The second channel is disposed along the length direction of the suction channel and communicates with the first channel and the third channel. The third channel communicates with the suction channel.

[0016] Wherein, one end of the flow equalization element is located within the second channel, and the other end is located within the third channel, simultaneously abutting against both the second channel and the third channel; and / or,

[0017] The flow equalization element is located within the second channel.

[0018] Furthermore, the regulating switch includes a blocking part and an regulating part connected to each other. The regulating part is provided with a plurality of regulating holes, which are sequentially arranged in the regulating part along the movement path of the regulating switch.

[0019] Furthermore, along the outer side of the main body to the suction channel, the distance between the adjusting part and the inner wall of the main body is less than the distance between the through hole and the inner wall of the main body.

[0021] The blocking part is provided with a deformation groove on the side wall facing the main body.

[0022] Furthermore, an adjustment groove is sequentially provided on the side of the adjustment switch facing the inner wall of the main body, and a plurality of adjustment holes are sequentially distributed along the length of the adjustment groove in the adjustment groove.

[0023] Furthermore, the flow area ratio of the regulating hole to the air inlet is 1:(2-10); and / or,

[0024] The opening of the adjustment hole is rounded.

[0025] Compared with the prior art, the embodiments of this application have the following main advantages:

[0026] When the gas flows in the air inlet, it will come into contact with the flow equalization element.

[0043] To address the aforementioned issues, Z in the diagram represents the vertical direction, X represents the horizontal direction, and the dashed arrows indicate the gas flow phase.

[0044] Please refer to Figures 1-4 This application provides an aerosol generating device 10, comprising:

[0045] An aerosol generating device 10 includes:

[0046] The main body 100 is provided with an air inlet (including a first sub-air inlet 110) and a suction channel 130, and the air inlet is connected to the suction channel 130.

[0047] Adjustment switch 300 blocks the air inlet and is provided with multiple adjustment holes 321 for moving or rotating relative to the air inlet to reduce the conduction area of ​​the air inlet.

[0048] The flow equalization component 200 abuts against the inner wall of the air inlet and is located between the regulating switch 300 and the suction channel 130. The flow equalization component 200 is provided with a through hole 210, which is used to guide the air inlet.

[0049] In this embodiment, as the gas enters the main body 100 from the external environment, the airflow area decreases and then expands as the main body 100 is typically thin, resulting in a diffused airflow. When this gas flows within the air inlet, it contacts the flow equalization element 200, which abuts against the inner wall of the air inlet. This flow equalization element 200 restricts the dispersed gas, causing it to converge into the through-hole 210, where it is rectified into a uniform shape before moving towards the suction channel 130. In summary, the flow equalization element 200 in this embodiment ensures a uniform airflow when entering the suction channel 130, ultimately maintaining a consistent temperature and flavor for each breath of aerosol inhaled by the user, thus enhancing the user experience.

[0050] Further, please refer to Figures 2-5 The flow equalization element 200 is a porous elastic element or a porous liquid-absorbing element; and / or,

[0051] The ratio of the flow area of ​​the through hole 210 to the flow area of ​​the air inlet is 1:(1.5~5); and / or,

[0052] The flow equalization component 200 is integrally formed with the main body 100.

[0053] In this embodiment, when the flow equalization component 200 is a porous elastic component, the airflow passing through its numerous randomly distributed holes is dispersed, divided, and redistributed. This effectively disrupts large-scale gas vortices and high-speed jets, making the airflow smoother, more uniform, and with a more consistent velocity distribution. The ratio of the flow area of ​​the through hole 210 to the flow area of ​​the air inlet prevents the suction channel 130 from drawing too little airflow, thus affecting the taste, and also prevents the through hole 210 from being too large and unable to effectively integrate the airflow. When the flow equalization component 200 is a porous liquid-absorbing component, it can absorb the condensed liquid to a certain extent, thereby preventing this liquid from accumulating at the bottom of the air inlet and causing liquid leakage. When the flow equalization component 200 is integrally formed with the main body 100, the flow equalization component 200 is a protruding structure on the inner wall of the main body 100. This protruding structure reduces the flow area of ​​the air inlet to achieve the effect of flow equalization.

[0054] It should be understood that the flow equalization component 200 can be porous sound-absorbing cotton.

[0055] Further, please refer to Figures 1-5 The air inlet includes a first sub-air inlet 110 and a second sub-air inlet 120 that are independently arranged. The regulating switch 300 blocks the first sub-air inlet 110. The flow area of ​​the second sub-air inlet 120 is smaller than that of the first sub-air inlet 110. The flow equalization component 200 is disposed in the first sub-air inlet 110.

[0056] In this embodiment, when the regulating switch 300 blocks the first sub-air inlet 110 and the user inhales: First, the second sub-air inlet 120 and the first sub-air inlet 110 are different holes and are not directly connected. Therefore, even if the first sub-air inlet 110 is blocked by the regulating switch 300, the second sub-air inlet 120 can still guide external gas into the main body 100 to avoid negative pressure forming inside the main body 100 and causing liquid leakage.

[0057] Secondly, the second sub-air inlet 120 can accommodate sensors such as the microphone, so that when the regulating switch 300 blocks the first sub-air inlet 110, the microphone can still activate the heating elements such as the atomizing core assembly 400 in the suction channel 130 through gas flow to heat the aerosol to generate a medium.

[0058] Then, the flow area of ​​the second sub-inlet 120 is smaller than that of the first sub-inlet 110. Therefore, when the regulating switch 300 moves, the flow rate of gas allowed to flow into the main body 100 is larger than the flow rate of gas entering the main body 100 through the second sub-inlet 120, which can avoid the problem that the regulating switch 300 has too little effect on suction after adjustment.

[0059] Next, when the regulating switch 300 is turned on, the flow equalization component 200 can reduce the gas flow rate in the first sub-inlet 110, so that the flow rate and flow rate of the airflow entering the suction channel 130 from the first sub-inlet 110 and the second sub-inlet 120 are similar, so that the temperature and taste of the aerosol inhaled by the user are uniform.

[0060] Finally, when the regulating switch 300 is closed, the flow equalization element 200 can reduce the flow area from the second sub-inlet 120 to the first sub-inlet 110, thereby preventing airflow in the second sub-inlet 120 from flowing into the first sub-inlet 110, thus increasing the airflow rate inhaled by the user. In summary, the aerosol generating device 10 of this application can effectively prevent liquid leakage, ensure the activation of the atomizing core, and effectively regulate the airflow rate during inhalation.

[0061] Further, please refer to Figures 2-5 The second sub-inlet 120 includes an air passage, an air outlet, and multiple air inlets 121. The multiple air inlets 121 are connected to the same air passage and pass through the outer side wall of the main body 100. The air passage connects the air outlet and the air inlets 121, and the air outlet is connected to the suction channel 130.

[0062] In this embodiment, while keeping the internal flow area of ​​the second sub-inlet 120 unchanged, providing multiple inlets 121 can reduce the flow area between the second sub-inlet 120 and the external environment, thereby preventing external dust and fine particles from entering the second sub-inlet 120 and causing blockage, thus improving the service life of the aerosol generating device 10.

[0063] Further, please refer to Figures 2-5 The air inlet includes a first channel 111, a second channel 112 and a third channel 113. The first channel 111 is located on the side wall of the main body 100 and is connected to the external environment. The second channel 112 is located along the length of the suction channel 130 and is connected to the first channel 111 and the third channel 113. The third channel 113 is connected to the suction channel 130.

[0064] The flow equalization element 200 has one end located within the second channel 112 and the other end located within the third channel 113, simultaneously abutting against both the second channel 112 and the third channel 113; and / or,

[0065] The flow equalization element 200 is located within the second channel 112.

[0066] In this embodiment, when one end of the flow equalization element 200 is located in the second channel 112 and the other end is located in the third channel 113, it can simultaneously abut against two channels in different directions. Therefore, it can prevent the flow equalization element 200 from deviating from the preset position in the vertical or horizontal direction shown in the figure, thereby improving the structural strength of the aerosol generating device 10. When the flow equalization element 200 is as shown in the figure... Figure 4As shown, when located in the second channel 112, it can prevent the condensate from accumulating at the connection between the second channel 112 and the third channel 113, which would cause the flow equalization element 200 to be wetted and deformed, thereby avoiding problems such as uneven airflow caused by the deformation of the flow equalization element 200.

[0067] Further, please refer to Figures 2-3 and Figures 7-10 The regulating switch 300 includes a blocking part 310 and an regulating part 320 connected to each other. The regulating part 320 is provided with a plurality of regulating holes 321, which are arranged sequentially in the regulating part 320 along the movement path of the regulating switch 300.

[0068] like Figure 2 As shown, initially, the regulating switch 300 blocks the air inlet. Then, when air needs to enter through the air inlet, the regulating switch 300 moves or rotates to connect one or more of the regulating holes 321 with the air inlet. As the airflow passes through the regulating holes 321, its flow area decreases, thus reducing broadband noise. When it is necessary to increase the amount of aerosol drawn in, the regulating switch 300 moves or rotates again to increase the number of regulating holes 321 connected to the air inlet. At this time, the rate at which external gas enters the main body 100 increases, and the rate of aerosol generation also increases, but the diameter of a single regulating hole 321 remains unchanged, thus still preventing broadband noise. Since the air inlet can connect with multiple regulating holes 321, it is known that the diameter of a single regulating hole 321 is smaller than that of the air inlet. Therefore, when the airflow passes through multiple regulating holes simultaneously, it can increase the amount of external gas entering the main body 100 without generating broadband noise due to a larger flow area of ​​gas entering the main body 100.

[0069] In summary, the aerosol generating device 10 of this application can reduce the noise heard by the user while maintaining a high aerosol generation rate, thereby improving the user experience.

[0070] Further, please refer to Figures 2-3 and Figures 7-10 Along the outer side of the main body 100 to the suction channel 130, the distance between the adjusting part 320 and the inner wall of the main body 100 is less than the distance between the through hole 210 and the inner wall of the main body 100.

[0071] In this embodiment, the distance between the adjustment part 320 and the inner wall of the main body 100 is shown in Figure A, and the distance between the through hole 210 and the inner wall of the main body 100 is shown in Figure B. When A is less than B, it can prevent the adjustment part 320 from being blocked in the through hole 210 when the adjustment switch 300 is in the closed state, thereby improving the user's suction efficiency.

[0072] Further, please refer to Figures 2-3 and Figures 7-10The blocking portion 310 is provided with a plurality of elastic protrusions 311 facing the inner wall of the main body 100, and the elastic protrusions 311 abut against the inner wall of the main body 100; and / or,

[0073] The blocking part 310 has a deformation groove 312 on its side wall facing the main body 100.

[0074] In this embodiment, the elastic protrusion 311 is arranged along the direction (Z direction) of the second channel 112, which can be understood as the length direction of the elastic protrusion 311 being the Z direction. First, the elastic protrusion 311 can abut against the inner wall of the air inlet, thereby limiting the movement direction of the adjustment switch 300. Second, the elastic protrusion 311 is elastic, so when it abuts against the inner wall of the air inlet and slides along the inner wall of the air inlet, it can provide a flexible feel, thereby improving the user experience. When the blocking part 310 is provided with a deformation groove 312, the deformation groove 312 can allow the blocking part 310 to undergo slight deformation, further providing a flexible feel when the user controls the adjustment switch 300, thereby improving the user experience.

[0075] It should be understood that the elastic protrusion 311 can also be set in the deformation groove 312. When the elastic protrusion 311 is set in the deformation groove 312, there is a certain gap between the elastic protrusion 311 and the inner wall of the deformation groove 312. This gap can provide effective deformation space for the lateral deformation of the elastic protrusion 311, which in turn facilitates the installation of the adjustment switch 300 and the deformation of the elastic protrusion 311.

[0076] Further, please refer to Figures 2-3 and Figures 7-10 On the side of the adjustment switch 300 facing the inner wall of the main body 100, there is also an adjustment groove 322, and there are multiple adjustment holes 321 arranged sequentially along the length of the adjustment groove 322.

[0077] In this embodiment, compared to Figure 8 The regulating switch 300 in the middle, Figure 9 The regulating slot 322 of the regulating switch 300 can initially reduce the flow area of ​​the gas, and then the multiple regulating holes 321 can further reduce the flow area of ​​the gas passing through the regulating switch 300, thereby changing the gas flow rate in a stepwise manner to avoid sudden changes in gas flow rate causing unstable and uneven airflow; at the same time, the reduced flow area of ​​the regulating holes 321 can further avoid the generation of broadband noise.

[0078] Further, please refer to Figures 2-3 and Figures 7-10 The flow area ratio between the regulating hole 321 and the air inlet hole is 1:(2~10); and / or,

[0079] The opening of the adjustment hole 321 is rounded.

[0080] In this embodiment, when the flow area ratio of the regulating hole 321 to the air inlet is 1:(2~10), it can effectively reduce the gas flow rate entering the body 100 through the air inlet, thereby reducing the generation of broadband noise. Figures 5-6 As shown, when the opening of the regulating hole 321 is provided with a rounded corner, the rounded corner can prevent the airflow from separating and forming a large-scale vortex. At the same time, it can prevent the airflow from being separated at a right angle and causing pressure pulsation when the separated airflow collides with the main airflow. In summary, the rounded corner can further reduce the noise generated by the gas entering the main body 100.
