[0027] This embodiment provides an aerosol generating device.

[0028] Please refer to Figure 1-5 The aerosol generating device includes a housing assembly 100 , a heating element 200 and a flow guide element 300 .

[0029] Please refer to Figure 3-5 The housing assembly 100 has a connecting mounting cavity 110 and an air flow channel 120, and the mounting cavity 110 is used to accommodate an aerosol matrix 400. The heating element 200 is disposed in the housing assembly 100, and is used to heat the aerosol matrix 400 in the mounting cavity 110 to generate an aerosol. The flow guide 300 is disposed in the housing assembly 100 and is connected to the air flow channel 120. The flow guide 300 includes a main body 310 and a surrounding portion 320. The main body 310 has an internal flow channel 311, and the internal flow channel 311 is connected to the air flow channel 120. The surrounding portion 320 is disposed around the circumference of the main body 310 and divides the space in the air flow channel 120, so as to prevent the air flow flowing from the internal flow channel 311 into the air flow channel 120 from generating an air flow vortex.

[0030] Please continue to refer to Figure 3-5 When the user uses the aerosol generating device, the airflow will flow into the airflow channel 120 through the internal flow channel 311 of the guide member 300. Since the surrounding portion 320 of the guide member 300 separates the space in the airflow channel 120, after the airflow enters the airflow channel 120 from the internal flow channel 311, the surrounding portion 320 will hinder the diffusion of the airflow in the airflow channel 120, thereby avoiding sudden changes in the air pressure of the airflow, which is beneficial to reduce the possibility of the airflow discharged from the internal flow channel 311 to the airflow channel 120 generating an airflow vortex.

[0031] It should be noted that, due to the structural design of the aerosol generating device, the airflow may enter a wider flow channel from a narrower flow channel during the flow of the airflow in the aerosol generating device. After the airflow enters the wider flow channel, it will quickly diffuse to the surrounding space, thereby causing the air pressure of the airflow to drop suddenly, and it is easy to generate airflow vortex. In this embodiment, the surrounding portion 320 is used to separate the space in the airflow channel 120, so that after the airflow enters the airflow channel 120 from the internal flow channel 311, the surrounding portion 320 will hinder the diffusion of the airflow in the airflow channel 120, thereby helping to reduce the degree of pressure change after the airflow enters the airflow channel 120, and further helping to reduce the possibility of generating airflow vortex.

[0032] Please refer to Figure 3-5 In one embodiment, the guide member 300 is disposed in the air flow channel 120, the air flow channel 120 includes an air inlet channel 121 and an air outlet channel 122, the internal flow channel 311 has an inlet 3111 and an outlet 3112, the inlet 3111 is located on the side wall of the first end of the main body 310, and the outlet 3112 is located at the second end of the main body 310. The first end of the main body 310 extends into the air outlet channel 122, and the second end of the main body 310 is connected to the air inlet channel 121.

[0033] When the user uses the aerosol generating device, the gas enters the aerosol generating device from the air inlet channel 121, and then passes through the internal flow channel 311 and the air outlet channel 122 of the flow guide 300 in sequence, and drives the aerosol to flow out from the air outlet channel 122. Specifically, the inlet 3111 of the internal flow channel 311 is connected to the air inlet channel 121, and the outlet 3112 of the internal flow channel 311 extends into the air outlet channel 122, so that the airflow in the air inlet channel 121 first enters the internal flow channel 311 from the inlet 3111, and then is discharged from the outlet 3112 into the air outlet channel 122.

[0034] Please refer to Figure 3-5 In one embodiment, the main body 310 has a first end and a second end that are oppositely disposed, and the second end has a deposition seat 312. The surrounding portion 320 extends in a spiral shape from the first end of the main body 310 to the second end of the main body 310 to guide the aerosol that flows back into the airflow channel 120 to be deposited on the deposition seat 312.

[0035] On the one hand, the spiral surrounding portion 320 serves to separate the space in the airflow channel 120, that is, the spiral surrounding portion 320 hinders the diffusion of the airflow flowing from the internal flow channel 311 to the airflow channel 120, so that the airflow can only flow and diffuse along a spiral path in the space where the surrounding portion 320 is located, thereby helping to reduce the possibility of generating airflow vortices. On the other hand, when the aerosol flows back into the airflow channel 120, the spiral surrounding portion 320 can guide the aerosol to flow along the spiral movement path to the deposition seat 312 and deposit on the deposition seat 312, thereby preventing the aerosol flowing back into the airflow channel 120 from affecting the user's experience.

[0036] Please continue to refer to Figure 3-5It should be noted that when a user uses an aerosol generating device, he or she may inhale the aerosol generated by the aerosol generating device. When the user inhales, the airflow generated by the inhalation will pass through the airflow channel 120 and the guide member 300, and the aerosol may easily flow back into the airflow channel 120 during the interval between inhalations. The guide member 300 of this embodiment uses a spiral surrounding portion 320, which, on the one hand, does not generate an airflow vortex when the airflow enters the airflow channel 120 from the internal flow channel 311, thereby making the user's inhalation smoother. On the other hand, when the aerosol flows back into the airflow channel 120, the aerosol can be guided to be deposited on the deposition seat 312, thereby preventing the refluxed aerosol from affecting the user's inhalation taste.

[0037] Specifically, in this embodiment, the deposition seat 312 and the inner wall of the gas outlet channel 122 are enclosed to form a space for accommodating the deposited aerosol. In other embodiments, the deposition seat 312 may also have a accommodating groove for accommodating the deposited aerosol.

[0038] Of course, in other embodiments, the shape of the surrounding portion 320 is not limited to the spiral shape.

[0039] For example, in another embodiment, the main body 310 has a first end and a second end that are oppositely disposed, and the second end has a deposition seat 312. The surrounding portion 320 surrounds the main body 310 along its circumference, and the surrounding portion 320 has a through flow guide hole (not shown) for guiding the aerosol that flows back into the airflow channel 120 to be deposited on the deposition seat 312.

[0040] The surrounding portion 320 enclosed along the circumference of the main body 310 can also play a role in reducing the possibility of generating airflow vortices. In this case, the surrounding portion 320 can be configured in a ring shape. The aerosol flowing back into the airflow channel 120 can be guided to be deposited on the deposition seat 312 through the through-flow guide hole.

[0041] Please refer to Figure 3-5 In one embodiment, a first sealing portion 313 is provided on the side wall of the deposition seat 312 , and the first sealing portion 313 abuts against the inner wall of the gas outlet channel 122 .

[0042] The first sealing portion 313 seals the gap between the side wall of the deposition seat 312 and the inner wall of the gas outlet channel 122. On the one hand, it is helpful to improve the airtightness of the installation between the flow guide 300 and the gas outlet channel 122, so that the gas will not enter the gas outlet channel 122 from the assembly gap between the flow guide 300 and the gas outlet channel 122. On the other hand, it is also helpful to prevent the aerosol deposited on the deposition seat 312 from leaking from the assembly gap between the flow guide 300 and the gas outlet channel 122.

[0043] Please refer to Figure 3-5In one embodiment, the deposition seat 312 has a second sealing portion 314 on a side away from the surrounding portion 320 , and the second sealing portion 314 abuts against an end of the gas outlet channel 122 .

[0044] The assembly gap between the guide member 300 and the air outlet channel 122 is further sealed by the second sealing portion 314 , thereby facilitating further improving the air tightness of the installation between the guide member 300 and the air outlet channel 122 .

[0045] Please refer to Figure 4 and 5 In one embodiment, the length of the spiral surrounding portion 320 from the first end to the second end is a, and the value range of a is 4.5 mm ≤ a ≤ 6.5 mm. The pitch of the spiral surrounding portion 320 is b, and the value range of b is 2 mm ≤ b ≤ 4 mm. The thickness of the surrounding portion 320 is c, and the value range of c is 0.4 mm ≤ c ≤ 0.6 mm.

[0046] By rationally designing the length, pitch and thickness of the spiral surrounding portion 320 from the first end to the second end, the surrounding portion 320 can better prevent the generation of airflow vortices and guide the aerosol deposition of the backflow. Specifically, the length a of the surrounding portion 320 can be 4.5 mm, 5 mm, 5.5 mm, 6 mm or 6.5 mm. The pitch b of the surrounding portion 320 can be 2 mm, 2.5 mm, 3 mm, 3.5 mm or 4 mm. The thickness of the surrounding portion 320 can be 0.4 mm, 0.5 mm or 0.6 mm.

[0047] Please refer to Figure 4 and 5 In one embodiment, the shape of the outlet 3112 is circular, and the diameter of the outlet 3112 is d, and the value range of d is 0.6mm≤c≤1.5mm.

[0048] By properly designing the shape and size parameters of the outlet 3112, it is helpful to control the flow rate and air pressure of the airflow when it is discharged from the outlet 3112 within a suitable range, thereby improving the user experience. Specifically, the diameter d of the outlet 3112 can be 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm or 1.5mm. Of course, in other embodiments, the shape of the outlet 3112 can also be a rectangle, a triangle or other suitable shapes.

[0049] Please refer to Figure 4 and 5 In one embodiment, the guide member 300 is an integrally formed structure.

[0050] The flow guide 300 is an integrated structure, which is beneficial to reducing the production cost of the flow guide 300 and reducing the operation steps of assembling the main body 310 and the surrounding part 320, thereby improving production efficiency. Specifically, the flow guide 300 can be integrally formed by injection molding.

[0051] Please refer to Figure 4 and 5 In one embodiment, the guide member 300 is made of silicone material. The guide member 300 made of silicone material has good flexibility and sealing performance, and is more likely to achieve close cooperation with the air inlet channel 121 and the air outlet channel 122.

[0052] Please refer to Figure 1-3 In one embodiment, the aerosol generating device further comprises an aerosol substrate 400, and the aerosol substrate 400 comprises a suction section 410 and a substrate section 420. The substrate section 420 is used to generate aerosol under a heating environment. The suction section 410 is arranged outside the housing assembly 100 for a user to inhale the aerosol.

[0053] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
