Detailed Implementation Methods

[0040] This application provides an airflow assembly 10 for an atomizing device, as shown in Figures 1 and 2. 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 disposed opposite to each other. The first end 121 has a first groove 1202 and a second groove 1203. The first groove 1202 communicates with the first air passage 201 of the atomizing device, and the second groove 1203 communicates with the second air passage 301 of the atomizing device. The receiving cavity 1201 communicates with 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 disposed at the first end 121, and the air inlet channel 1204 communicates with 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.

[0041] 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.

[0042] 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.

[0043] In some embodiments, the first air passage 201 is the main air passage of the atomizing device, the second air passage 301 is the auxiliary air passage of the atomizing device, the pneumatic sensor 110 is disposed near the first groove 1202, and the accommodating cavity 1201 for mounting the pneumatic sensor 110 is connected to the first groove 1202, so that the pneumatic sensor 110 can first sense the flow of air in the first air passage 201, and only start the atomizing device when there is air flow in the main air passage.

[0044] In some embodiments, the diversion channel 1205 includes a first diversion channel 12051, a second diversion channel 12052, and a third diversion channel 12053. The first diversion channel 12051 is connected to the first groove 1202, and the second diversion channel 12052 is connected to the second groove 1203. The first diversion channel 12051 and the second diversion channel 12052 both extend to one end of the third diversion channel 12053. The third diversion channel 12053 extends to one end of the intake channel 1204. The angle between the extension direction of the first diversion channel 12051 and the extension direction of the third diversion channel 12053 is smaller than the angle between the extension direction of the second diversion channel 12052 and the extension direction of the third diversion channel 12053. When airflow flows from intake channel 1204 through third diversion channel 12053 to first diversion channel 12051 and second diversion channel 12052, the airflow is almost unobstructed from the third diversion channel 12053 to the first diversion channel 12051 because the extension direction of the first diversion channel 12051 is close to that of the third diversion channel 12053. The change in airflow direction is small, so the airflow is easier to flow along the first diversion channel 12051. However, since the extension direction of the second diversion channel 12052 is significantly different from that of the third diversion channel 12053, the airflow is more obstructed from the third diversion channel 12053 to the second diversion channel 12052. The change in airflow direction is large, so the airflow is more difficult to flow along the second diversion channel 12052 than along the first diversion channel 12051. In other words, after the airflow is diverted from the third diversion channel 12053, the airflow towards the first groove 1202 reaches the first air passage 201 first, and then the airflow towards the second groove 1203 reaches the second air passage 301. This ensures that the airflow in the secondary air passage flows first, preventing the aroma in the main air passage from being insufficient and affecting the overall taste and user experience. At the same time, it also prevents the pneumatic sensor 110 from failing to respond when there is airflow in the second air passage 301, which would result in a poor user experience.

[0045] In some embodiments, the third diversion channel 12053 diverts the flow near the first groove 1202, and the length of the first diversion channel 12051 is less than that of the second diversion channel 12052, so as to ensure that the gas in the first air passage 201 flows before the gas in the second air passage 301.

[0046] In some other embodiments, the third diversion channel 12053 may also branch out into multiple channels. For example, the number of channels branched out by the third diversion channel 12053 may be 3, 4, 6, etc. The atomizing device may be provided with multiple air channels for generating aerosols, and the channels branched out by the third diversion channel 12053 correspond one-to-one with the air channels for generating aerosols. The angle between the extension direction of the first diversion channel 12051 and the extension direction of the third diversion channel 12053 is smaller than the angle between the extension directions of the other channels and the extension direction of the third diversion channel 12053.

[0047] In some embodiments, as shown in Figures 3 and 4, the first end 121 is provided with a first wall 1271 and a second wall 1272. A first groove 1202 is defined by the first wall 1271, and a second groove 1203 is defined by the second wall 1272. The first groove 1202 and the second groove 1203 can both be cylindrical. The first wall 1271 is provided with a third opening 12023 on the side near the air intake channel 1204 to allow airflow to enter the first groove 1202, and the second wall 1272 is provided with a fourth opening 12033 on the side away from the air intake channel 1204 to allow airflow to enter the second groove 1203.

[0048] In some embodiments, a guide wall 1274 is connected to the outer peripheral surface of the first wall 1271. The guide wall 1274 is curved and extends from the side wall of the third opening 12023 to near the fourth opening 12033. A second diversion channel 12052 is formed between the guide wall 1274 and the second wall 1272. The airflow flowing out of the third diversion channel 12053 can collide with the guide wall 1274 and be guided by the guide wall 1274 to the second groove 1203.

[0049] In some embodiments, as shown in FIG5, the second end 122 is provided with a mounting cavity 1206, which is used to mount the battery cell 40. An air intake channel 1204 is provided on the side wall of the mounting cavity 1206. One end of the air intake channel 1204 is connected to the third diversion channel 12053, and the other end is connected to the outside. The mounting cavity 1206 is connected to the outside, and the receiving cavity 1201 is connected to the mounting cavity 1206.

[0050] Specifically, the end of the accommodating cavity 1201 near the mounting cavity 1206 is connected to the mounting cavity 1206, and the end away from the mounting cavity 1206 is connected to the first groove 1202. External gas can flow from the mounting cavity 1206 through the accommodating cavity 1201 and into the first air passage 201, giving the airflow passing through the pneumatic sensor 110 an independent air passage, thereby effectively increasing the sensitivity of the pneumatic sensor 110. The air intake passage 1204 is located on the side wall of the mounting cavity 1206, which can bypass the battery cell 40 and connect to the outside, avoiding the airflow being blocked by the battery cell 40, improving the smoothness of the airflow, and enhancing the taste. At the same time, when the aerosol flows in the opposite direction, the aerosol can also be discharged from the atomizing device along the air intake passage 1204, preventing the battery cell 40 from being contaminated by the aerosol.

[0051] In some embodiments, as shown in Figures 4 and 7, the second end 122 of the airflow support 120 includes a first sidewall 124 and a second sidewall 125 disposed opposite to each other. A mounting cavity 1206 is formed between the first sidewall 124 and the second sidewall 125. The first sidewall 124 is provided with a first air inlet 12041 at one end near the first end 121 and a second air inlet 12042 at one end away from the first end 121. An air intake channel 1204 extends from the second air inlet 12042 to the first air inlet 12041. The area of ​​the second air inlet 12042 is larger than the area of ​​the first air inlet 12041. A second liquid suction member 160 is provided at the projection position of the first air inlet 12041 toward the second air inlet 12042. The second liquid suction member 160 can be used to absorb condensate or atomizing matrix and other liquids falling from the first air inlet 12041 to prevent liquid from flowing to the outside of the atomizing device.

[0052] In some embodiments, an extension 126 is connected to one end of the first sidewall 124 away from the first end 121. The extension 126 extends from the first sidewall 124 toward the second sidewall 125, and the second air inlet 12042 is at least partially disposed in the extension 126.

[0053] In some embodiments, as shown in FIG6, FIG8 and FIG9, the airflow assembly 10 further includes a first seal 130, which covers the first end 121 and forms a diversion channel 1205 with the first seal 130 and the first end 121.

[0054] In some embodiments, the first seal 130 has a protrusion 135 on the side facing the airflow support 120. The protrusion 135 is inserted into the diversion channel 1205. The shape of the protrusion 135 is adapted to the shape of the diversion channel 1205. The protrusion 135 and the first end 121 cooperate to form the diversion channel 1205.

[0055] In some embodiments, the first seal 130 is provided with a first boss 131 and a second boss 132. Both the first boss 131 and the second boss 132 are connected to the protrusion 135. The first boss 131 is provided with a first through hole 1301, and the second boss 132 is provided with a second through hole 1302. The first boss 131 is inserted into the first groove 1202 and is press-fitted with the side wall of the first groove 1202. The second boss 132 is inserted into the second groove 1203 and is press-fitted with the side wall of the second groove 1203. The first through hole 1301 and the first groove 1202 are connected, and the second through hole 1302 and the second groove 1203 are connected.

[0056] In some embodiments, the atomizing device includes a first air tube 210 and a second air tube 310, a first air passage 201 disposed within the first air tube 210, and a second air passage 301 disposed within the second air tube 310. The first air tube 210 is inserted into a first through hole 1301, and the second air tube 310 is inserted into a second through hole 1302. The sidewall of a first boss 131 is sealed between the sidewall of the first air tube 210 and the sidewall of the first groove 1202, and the sidewall of a second boss 132 is sealed between the sidewall of the second air tube 310 and the sidewall of the second groove 1203.

[0057] In some embodiments, the sidewall of the first through hole 1301 is provided with a raised rib that abuts against the first air pipe 210 to improve the interference sealing effect between the first boss 131 and the first air pipe 210, and the sidewall of the second through hole 1302 is provided with a raised rib that abuts against the second air pipe 310 to improve the interference sealing effect between the second boss 132 and the second air pipe 310.

[0058] In some embodiments, as shown in Figures 4 and 9, a first boss 131 is connected to a first connector 133, a second boss 132 is connected to a second connector 134, a first connecting hole 12021 is provided on the bottom wall of a first groove 1202, and a second connecting hole 12031 is provided on the bottom wall of a second groove 1203. The first connector 133 is inserted into the first connecting hole 12021 and is press-fitted with the side wall of the first connecting hole 12021, and the second connector 134 is inserted into the second connecting hole 12031 and is press-fitted with the side wall of the second connecting hole 12031. The first connector 133 and the second connector 134 are penetrated by the pins of the atomizing device so that the pins of the atomizing device extend from the first end 121 to the second end 122.

[0059] Specifically, the first connecting hole 12021 connects the first groove 1202 and the mounting cavity 1206, and the second connecting hole 12031 connects the second groove 1203 and the mounting cavity 1206. The pins of the first atomizer 20 of the atomizing device can pass through the first connector 133 and be electrically connected to the battery cell 40, and the pins of the second atomizer 30 of the atomizing device can pass through the second connector 134 and be electrically connected to the battery cell 40. The first connector 133 is interference-fitted with the pins of the first atomizer 20, and the second connector 134 is interference-fitted with the pins of the second atomizer 30.

[0060] In some embodiments, the first connector 133 and the second connector 134 are provided with blind holes on the side away from the battery cell 40. The pins are inserted into the blind holes and pierce the bottom wall of the blind holes so that the pins can pass through the first connector 133 and the second connector 134.

[0061] The first connector 133 and the second connector 134 ensure the sealing around the pins, preventing liquids such as condensate or atomizing matrix from leaking through gaps around the pins. Furthermore, the first connector 133 and the second connector 134 make the connection between the first seal 130 and the airflow support 120 more stable, and they can shape the first boss 131 and the second boss 132, preventing them from twisting during installation and ensuring a tight seal between the first boss 131, the second boss 132 and the airflow support 120.

[0062] In some embodiments, the outer periphery of both the first connector 133 and the second connector 134 is provided with raised ribs to improve the sealing connection effect between the first seal 130 and the airflow support 120.

[0063] In some embodiments, as shown in Figures 3 and 9, the outer edge of the first end 121 of the airflow support 120 is provided with a fixing groove 1208, and the outer edge of the first seal 130 is provided with a connecting portion 136. The connecting portion 136 is provided with a limiting block (not shown in the figure), and the limiting block and the fixing groove 1208 form a snap-fit ​​engagement.

[0064] In some embodiments, as shown in Figures 4 and 8, the sidewall of the first groove 1202 is provided with a first opening 12022 communicating with the first groove 1202, and the side of the first seal 130 facing the airflow support 120 is provided with a communicating groove 1303, and the accommodating cavity 1201 is connected to the first opening 12022 through the communicating groove 1303.

[0065] 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.

[0066] 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.

[0067] In some embodiments, the airflow support 120 may be made of rigid plastic, such as polycarbonate plastic, polyamide plastic, etc.

[0068] In some embodiments, as shown in Figures 7 to 10, the airflow assembly 10 further includes a second seal 150, which is sealed between the pneumatic sensor 110 and the airflow support 120. The second seal 150 has an inner cavity 1501, in which the pneumatic sensor 110 is mounted. One end of the second seal 150 near the first seal 130 has a first opening 1502 communicating with the inner cavity 1501, and the other 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 communicates with the first air passage 201 through a connecting groove 1303, and the second opening 1503 communicates with the outside through a mounting cavity 1206.

[0069] 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.

[0070] In some embodiments, the outer peripheral surface of the second seal 150 may be provided with ribs to improve the interference sealing effect between the second seal 150 and the airflow support 120.

[0071] In some embodiments, the material of the second seal 150 may be elastic rubber or plastic, specifically, the material of the second seal 150 may be silicone.

[0072] In some embodiments, as shown in FIG3, FIG4 and FIG10, the airflow assembly 10 further includes a first liquid suction member 140, and a receiving groove 1207 is provided at the first end 121. The first groove 1202 and the second groove 1203 are both in communication with the receiving groove 1207. The first liquid suction member 140 is disposed in the receiving groove 1207, and the shape of the first liquid suction member 140 is adapted to the shape of the receiving groove 1207.

[0073] In some embodiments, the first end 121 is provided with a groove 12101, and the first groove 1202, the second groove 1203, the diversion channel 1205, the accommodating cavity 1201 and the receiving groove 1207 are all located in the groove 12101. The bottom wall of the groove 12101 is provided with a convex wall 127, which defines the first groove 1202, the second groove 1203 and the accommodating cavity 1201. The receiving groove 1207 is located outside the diversion channel 1205 and is defined by the convex wall 127 and the side wall of the groove 12101.

[0074] In some embodiments, the sidewalls of the convex wall 127 and the groove 12101 cooperate to define a diversion channel 1205, and the angle between the extension direction of the first diversion channel 12051 and the extension direction of the third diversion channel 12053 is smaller than the angle between the extension direction of the second diversion channel 12052 and the extension direction of the third diversion channel 12053.

[0075] Specifically, the convex wall 127 includes a guide wall 1274, a first wall 1271 and a second wall 1272. A third diversion channel 12053 is formed between the second wall 1272 and the side wall of the groove 12101. The second diversion channel 12052 is formed between the second wall 1272 and the guide wall 1274. The convex wall 127 also includes a connecting wall 1273 extending from the side wall of the groove 12101 to the first wall 1271. The first diversion channel 12051 extends along the connecting wall 1273 to the first groove 1202.

[0076] 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.

[0077] In some implementations, the first wall 1271 has a first opening 12022, and the second wall 1272 has a second opening 12032. Both the first opening 12022 and the second opening 12032 are blocked by the first liquid-absorbing element 140. Liquids 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 absorbed by the first liquid-absorbing element 140 through the first opening 12022 and the second opening 12032, thus preventing leakage of condensate and other liquids into the battery cell 40.

[0078] In some embodiments, the first liquid-absorbing member 140 and the second liquid-absorbing member 160 are made of a material with liquid-absorbing properties. Specifically, the first liquid-absorbing member 140 and the second liquid-absorbing member 160 can be condensation cotton.

[0079] In some embodiments, a stop 128 is provided in both the first groove 1202 and the second groove 1203. The height of the stop 128 is less than the depth of the first groove 1202 and less than the depth of the second groove 1203. The stop 128 can limit the insertion of the first air tube 210 into the first groove 1202 and the second air tube 310 into the second groove 1203.

[0080] This application also provides an atomizing device, as shown in Figures 11 and 12. The atomizing device includes the airflow assembly 10 of the above embodiment. The atomizing device also includes a first atomizer 20, at least one second atomizer 30, and a battery 40.

The battery 40 is used to supply power to the first atomizer 20 and the second atomizer 30.

[0081] In some embodiments, the atomizing device further includes a mouthpiece 80, and the first airway 201 and the second airway 301 are both connected to the mouthpiece 80.

[0082] In some embodiments, the first atomizer 20 includes a first atomizing chamber 220, the second atomizer 30 includes a second atomizing chamber 320, and the airflow assembly 10 is sealed to one end of the first atomizing chamber 220 away from the mouthpiece 80 and to one end of the second atomizing chamber 320 away from the mouthpiece 80. The outer peripheral surface of the connecting portion 136 of the first seal 130 is provided with raised ribs to enhance the interference sealing effect between the airflow assembly 10 and the first atomizing chamber 220 and the second atomizing chamber 320.

[0083] In some embodiments, the first atomizing chamber 220 and the second atomizing chamber 320 are fixedly connected so that the airflow assembly 10 can be simultaneously and sealed to both the first atomizing chamber 220 and the second atomizing chamber 320, thereby improving installation efficiency. Specifically, the first atomizing chamber 220 and the second atomizing chamber 320 can be integrally formed.

[0084] In some embodiments, the number of second atomizers 30 is one or more. Specifically, the number of second atomizers 30 can be 1, 2, 3, 5, etc. When there are multiple second atomizers 30, the multiple second atomizers 30 are arranged side by side along the extension direction of the second air passage 301, and the second air passages 301 of the multiple second atomizers 30 are connected sequentially. Among them, the second atomizer 30 closest to the airflow assembly 10 is fixedly connected to the first atomizer 20, and the remaining second atomizers 30 can be detachably connected to the first atomizer 20.

[0085] In some embodiments, the atomizing device includes three second atomizers 30 located on the same side of the first atomizer 20, and the total length of the three second atomizers 30 stacked together may be equal to or close to the length of the first atomizer 20.

[0086] In some embodiments, as shown in Figures 13 to 15, the atomizing device further includes a housing 50. A switch 90, slidably connected to the end of the housing 50 away from the nozzle 80, is provided with an air inlet 901. An air guide 91 is provided between the switch 90 and the extension 126. The air guide 91 has a protruding edge 911 on the side facing the extension 126, forming a first air guide groove 9101. The shape of the air guide groove 9101 is adapted to the second air inlet 12042. The protruding edge 911 is inserted into the second air inlet 12042 and sealed to the side wall of the second air inlet 12042. An air guide hole 9102 is provided on the bottom wall of the air guide groove 9101, communicating with the second air inlet 12042. When the switch 90 is in the open state, the air inlet 901 is connected to the air guide 9102, and the external airflow can enter the second air inlet 12042 along the air inlet 901 and the air guide 9102. The air guide 91 can ensure that all the airflow entering through the air inlet 901 can enter the second air inlet 12042 to avoid air leakage.

[0087] In some embodiments, as shown in FIG13, the air guide 91 is provided with a rib on the side away from the extension 126. The rib is arranged around the air guide hole 9102 to form a second air guide groove 9103. The switch 90 abuts against the rib. When the switch 90 is in the closed state, the air inlet 901 is blocked by the rib and does not communicate with the second air guide groove 9103. When the switch 90 is in the open state, the air inlet 901 communicates with the second air guide groove 9103.
