[0035] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is explicitly and implicitly understood that the embodiments described herein can be combined with other embodiments.

[0036] The embodiments of the present application provide an airflow assembly 10 for an atomizing device, such as Figure 1 and Figure 2As shown, the airflow assembly 10 includes a pneumatic sensor 110 and an airflow support 120. The airflow support 120 has a receiving cavity 1201, in which the pneumatic sensor 110 is installed. The airflow support 120 includes a first end 121 and a second end 122 arranged opposite to each other. The first end 121 has a first groove 1202 and a second groove 1203. The first groove 1202 is connected to the first air passage 201 of the atomizing device, and the second groove 1203 is connected to the second air passage 301 of the atomizing device. The receiving cavity 1201 is connected to the first groove 1202. The airflow support 120 also has an air inlet channel 1204 and a diversion channel 1205. The diversion channel 1205 is located at the first end 121, and the air inlet channel 1204 is connected to the first groove 1202 and the second groove 1203 through the diversion channel 1205. External gas can flow into the diversion channel 1205 through the air inlet channel 1204 and be divided into two airflows by the diversion channel 1205. The two airflows flow to the first air passage 201 through the first groove 1202 and to the second air passage 301 through the second groove 1203, respectively. By setting the airflow bracket 120, this application can divert the airflow to the first air passage 201 and the second air passage 301. The structure is simple, allowing the airflow to be smoother and cleaner, avoiding contamination of the airflow by other components, which helps to save costs and improve installation efficiency. At the same time, the diversion channel 1205 is located at the first end 121, and the airflow is only diverted when it is close to the first air passage 201 and the second air passage 301, making the airflow path simpler and easier to control. It can effectively prevent the airflow from leaking after diversion, which helps to improve the stability and consistency of the taste of the atomizing device.

[0037] Specifically, the pneumatic sensor 110 can be a sensor such as a microphone that can sense gas flow or changes in air pressure. The airflow passing through the pneumatic sensor 110 can flow from the accommodating cavity 1201 to the first groove 1202 and enter the first air passage 201. When the user uses the atomizing device, a negative pressure is formed in the first air passage 201. The external airflow is diverted from the air inlet channel 1204 through the diversion channel 1205 to the first air passage 201 and the second air passage 301. The pneumatic sensor 110 senses the negative pressure in the first air passage 201 and then activates the atomizing device, causing the first air passage 201 and / or the second air passage 301 to generate aerosol.

[0038] In some embodiments, the accommodating cavity 1201 is disposed near the first groove 1202, and the second groove 1203 communicates with the accommodating cavity 1201 through the first groove 1202. Compared with the second air passage 301, the gas flow in the first air passage 201 can be detected by the pneumatic sensor 110 more quickly.

[0039] In some embodiments, the first air channel 201 is a main air channel of the atomization device, the second air channel 301 is a secondary air channel of the atomization device, the pneumatic sensor 110 is arranged close to the first recess 1202, and the accommodating cavity 1201 for arranging the pneumatic sensor 110 is in communication with the first recess 1202, so that the pneumatic sensor 110 can first sense the flow of the airflow in the first air channel 201, and the atomization device is started only when the airflow flows in the main air channel.

[0040] In some embodiments, the shunt channel 1205 includes a first shunt channel 12051, a second shunt channel 12052, and a third shunt channel 12053, the first shunt channel 12051 is in communication with the first recess 1202, the second shunt channel 12052 is in communication with the second recess 1203, the first shunt channel 12051 and the second shunt channel 12052 both extend from one end of the third shunt channel 12053, the third shunt channel 12053 extends from one end of the air inlet channel 1204, and the angle between the extension direction of the first shunt channel 12051 and the extension direction of the third shunt channel 12053 is smaller than the angle between the extension direction of the second shunt channel 12052 and the extension direction of the third shunt channel 12053. When the airflow flows from the air inlet channel 1204 to the first shunt channel 12051 and the second shunt channel 12052 through the third shunt channel 12053, the airflow flowing from the third shunt channel 12053 to the first shunt channel 12051 is hardly blocked, and the airflow direction changes little, so the airflow is more likely to flow along the first shunt channel 12051; since the extension direction of the second shunt channel 12052 and the extension direction of the third shunt channel 12053 change greatly, the airflow flowing from the third shunt channel 12053 to the second shunt channel 12052 is greatly blocked, and the airflow direction changes greatly, so the airflow is more difficult to flow along the second shunt channel 12052 than along the first shunt channel 12051. That is, after the airflow is shunted from the third shunt channel 12053, the airflow towards the first recess 1202 first reaches the first air channel 201, and the airflow towards the second recess 1203 reaches the second air channel 301, so as to ensure that the airflow in the secondary air channel flows after the airflow in the main air channel, and avoid that the main air channel is not full of aroma, affecting the overall taste style and user experience. At the same time, it can also avoid that the pneumatic sensor 110 does not respond when there is airflow in the second air channel 301, resulting in poor experience.

[0041] In some embodiments, the third shunt channel 12053 is shunted close to the first recess 1202, and the length of the first shunt channel 12051 is smaller than that of the second shunt channel 12052, so as to ensure that the airflow in the first air channel 201 flows before the airflow in the second air channel 301.

[0042] In some other embodiments, the third shunt channel 12053 can also shunt out multiple channels, for example, the third shunt channel 12053 can shunt out 3, 4, 6, etc. number of channels. The atomization device can be provided with multiple air passages for generating aerosol, and the channels shunted out by the third shunt channel 12053 correspond one-to-one to the air passages for generating aerosol, wherein the included angle between the extension direction of the first shunt channel 12051 and the extension direction of the third shunt channel 12053 is smaller than the included angle between the extension direction of the other channels and the extension direction of the third shunt channel 12053.

[0043] In some embodiments, as shown in Figure 3 and Figure 4 The first end portion 121 is provided with a first wall 1271 and a second wall 1272, the first recess 1202 is defined by the first wall 1271, and the second recess 1203 is defined by the second wall 1272. The shapes of the first recess 1202 and the second recess 1203 can both be cylindrical, the first wall 1271 is provided with a third opening 12023 on the side close to the air inlet channel 1204 to allow airflow to enter the first recess 1202, and the second wall 1272 is provided with a fourth opening 12033 on the side away from the air inlet channel 1204 to allow airflow to enter the second recess 1203.

[0044] In some embodiments, the outer circumferential surface of the first wall 1271 is connected with a guide wall 1274, the guide wall 1274 is curved and extends from the side wall of the third opening 12023 to the position close to the fourth opening 12033, the second shunt channel 12052 is formed between the guide wall 1274 and the second wall 1272, and the airflow shunted out by the third shunt channel 12053 can collide with the guide wall 1274 and be guided to the second recess 1203 by the guide wall 1274.

[0045] In some embodiments, as shown in Figure 5 The second end portion 122 is provided with a mounting cavity 1206 for mounting the battery cell 40, the air inlet channel 1204 is arranged on the side wall of the mounting cavity 1206, one end of the air inlet channel 1204 communicates with the third shunt channel 12053, and the other end communicates with the outside, the mounting cavity 1206 communicates with the outside, and the containing cavity 1201 communicates with the mounting cavity 1206.

[0046] Specifically, the accommodation cavity 1201 is in communication with the mounting cavity 1206 at one end close to the mounting cavity 1206 and in communication with the first recess 1202 at one end away from the mounting cavity 1206, so that external gas can flow from the mounting cavity 1206 through the accommodation cavity 1201 and into the first air passage 201, so that the gas flow through the pneumatic sensor 110 has an independent air passage, so as to effectively increase the sensitivity of the pneumatic sensor 110. The air inlet channel 1204 is arranged on the side wall of the mounting cavity 1206 and can bypass the battery cell 40 to communicate with the outside, so as to avoid the obstruction of the battery cell 40 to the gas flow, improve the smoothness of the gas flow, and improve the taste. At the same time, when the aerosol flows in the reverse direction, the aerosol can also flow out of the atomization device along the air inlet channel 1204, so as to avoid the pollution of the battery cell 40 by the aerosol.

[0047] In some embodiments, as shown in Figure 4 and Figure 7 , the second end 122 of the gas flow support 120 includes oppositely arranged first and second side walls 124 and 125, and the mounting cavity 1206 is formed between the first and second side walls 124 and 125. The first side wall 124 is provided with a first air inlet 12041 at one end close to the first end 121, and is provided with a second air inlet 12042 at one end away from the first end 121. The air inlet channel 1204 extends from the second air inlet 12042 to the first air inlet 12041. The area of the second air inlet 12042 is greater than the area of the first air inlet 12041. The first air inlet 12041 is provided with a second liquid absorbing member 160 at a projection position facing the second air inlet 12042. The second liquid absorbing member 160 can be used to absorb liquid such as condensed liquid or atomized substrate falling from the first air inlet 12041, so as to prevent the liquid from flowing to the outside of the atomization device.

[0048] In some embodiments, the first side wall 124 is connected with an extension 126 at one end away from the first end 121. The extension 126 extends from the first side wall 124 toward the second side wall 125. The second air inlet 12042 is at least partially arranged in the extension 126.

[0052] In some embodiments, the atomization device includes a first air tube 210 and a second air tube 310, the first airway 201 is arranged in the first air tube 210, and the second airway 301 is arranged in the second air tube 310.

[0061] Specifically, the length of the first protrusion 131 inserted into the first groove 1202 is less than the depth of the first groove 1202, so that the first protrusion 131 will not close the first opening 12022 when inserted into the first groove 1202. External gas can enter the receiving cavity 1201 through the mounting cavity 1206, and then enter the first air passage 201 from the receiving cavity 1201 through the connecting groove 1303, the first opening 12022, and the first groove 1202, forming an independent air passage flowing through the pneumatic sensor 110.

[0062] In some embodiments, the first seal 130 may be made of elastic rubber or plastic, specifically, the first seal 130 may be made of silicone.

[0063] In some embodiments, the airflow support 120 may be made of rigid plastic, such as polycarbonate plastic, polyamide plastic, etc.

[0064] In some embodiments, such as Figures 7 to 10 As shown, the airflow assembly 10 also includes a second seal 150, which is sealed between the pneumatic sensor 110 and the airflow bracket 120.

The end of the second seal 150 near the first seal 130 has a first opening 1502 communicating with the inner cavity 1501, and the end of the second seal 150 away from the first seal 130 has a second opening 1503 communicating with the inner cavity 1501. The first opening 1502 is connected to the first air passage 201 through a connecting groove 1303, and the second opening 1503 is connected to the outside through a mounting cavity 1206.

[0065] In some embodiments, the sidewall of the connecting groove 1303 is sealed to the side of the second seal 150 near the first seal 130. The side of the pneumatic sensor 110 near the first seal 130 is connected through the first opening 1502, the connecting groove 1303, and the first air passage 201. When the user uses the atomizing device to inhale, due to the sealed connection between the first seal 130 and the airflow support 120, a negative pressure is generated in the first air passage 201, resulting in an air pressure lower than atmospheric pressure in the space between the pneumatic sensor 110 and the first seal 130. Meanwhile, the side of the pneumatic sensor 110 away from the first seal 130 is connected to the outside through the second opening 1503 and the mounting cavity 1206, and the air pressure is maintained at atmospheric pressure. The pneumatic sensor 110 detects that the air pressure near the first end 121 is lower than the atmospheric pressure near the second end 122, thus forming a negative pressure environment, and activates the atomizing device when the pressure difference reaches a certain threshold.

The first diversion channel 12051 extends along the connecting wall 1273 to the first groove 1202.

[0072] In some embodiments, the convex wall 127 may define a curved diversion channel 1205 so that the airflow is smooth and unobstructed after it comes out of the air intake channel 1204, resulting in a better suction experience.

[0073] In some embodiments, the first wall 1271 is provided with a first opening 12022, and the second wall 1272 is provided with a second opening 12032, both the first opening 12022 and the second opening 12032 being blocked by the first liquid suction member 140. The liquid such as condensate generated by the first air passage 201 and the second air passage 301 can fall into the first groove 1202 and the second groove 1203, and then be adsorbed by the first liquid suction member 140 through the first opening 12022 and the second opening 12032, so as to avoid the liquid such as condensate from leaking to the battery cell 40.

[0074] In some embodiments, the first liquid suction member 140 and the second liquid suction member 160 are made of a material having a liquid adsorption property. Specifically, the first liquid suction member 140 and the second liquid suction member 160 can be condensing cotton.
