Thus, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, not all of which refer to the same embodiment. Furthermore, in one or more embodiments, the specialized features, structures, or characteristics may be combined in any suitable manner.

Please refer to Figures 1 to 5 together, and the air guide structure provided in the embodiment of the utility model will now be described. The air guide structure provided in the embodiment of the utility model is suitable for an atomizing device. By introducing air into the atomizer 6 of the atomizing device through the air guide structure, it can prevent the atomized liquid and/or condensed liquid in the atomizer 6 from infiltrating into the microphone switch along the air inlet channel 131, causing the atomized liquid and/or condensed liquid to corrode/soak the microphone switch and cause the microphone switch to malfunction or be damaged. The atomizing device mentioned in the embodiment of the utility model generally includes an atomizer 6 and a power supply device electrically connected to the atomizer 6. When the atomizing device is in use, the power supply device can provide electrical energy to the atomizer 6, and the atomizer 6 heats and atomizes the atomized liquid under the action of electric drive, and the aerosol formed by the atomization of the atomized liquid can be inhaled by the user.

Please further refer to Figures 1, 2 and 4. The air guide structure provided by the embodiment of the utility model includes an air guide component 1 and a pneumatic switch 2. The air guide component 1 can be installed on the atomizer 6 of the atomizing device. The air guide component 1 is provided with an air inlet hole 111, an air inlet channel 131 and a branch airway 15. The air inlet 111 on the atomizer 6 can introduce external air into the atomizing channel or atomizing chamber inside the atomizer 6. The air inlet channel 131 on the air guide component 1 connects the air inlet 111 with the air inlet 61 of the atomizer 6. The branch airway 15 connects the air inlet channel 131 and connects with the pneumatic switch 2. The air inlet 61 of the atomizer 6 is connected to the atomizing channel or atomizing chamber inside the atomizer 6. The atomizer 6 is also provided with a vent 62 for the user to inhale the aerosol. The first end of the vent 62 is connected to the atomizing channel or atomizing chamber inside the atomizer 6. The atomizing channel or atomizing chamber is provided with an atomizing core 63 that can atomize the aerosol to form an aerosol. The second end of the vent 62 extends out of the atomizer 6. The pneumatic switch 2 is arranged at a position corresponding to the branch airway 15 on the air guide component 1. The pneumatic switch 2 can sense the airflow or air pressure changes in the branch airway 15 to automatically trigger the atomizer 6 to start working. It should be noted that the pneumatic switch 2 can be but is not limited to a microphone switch. The air guide assembly 1 is also provided with a first liquid collecting tank 112 for collecting atomized liquid and/or condensed liquid. The first liquid collecting tank 112 is located below the branch airway 15. The notch of the first liquid collecting tank 112 is connected to the branch airway 15, so that the atomized liquid and/or condensed liquid deposited on the inner wall of the branch airway 15 can converge into the first liquid collecting tank 112. When the atomizer 6 is working, the user inhales through the second end port of the ventilation tube 62. Under the negative pressure formed by the suction, the external air is introduced into the air inlet channel 131 through the air inlet hole 111. The air introduced into the air inlet channel 131 continues to flow into the atomization channel or atomization chamber of the atomizer 6 through the air inlet 61 of the atomizer 6, and is mixed with the aerosol in the atomization channel or atomization chamber. The mixed aerosol is carried by the suction airflow and is drained into the user's mouth through the ventilation tube 62. It should be noted that when external air is introduced into the air inlet channel 131 through the air inlet hole 111, the branch airway 15 connected to the air inlet channel 131 will produce airflow or air pressure changes under the action of the suction negative pressure. After the pneumatic switch 2 senses the airflow or air pressure changes in the branch airway 15, it will automatically trigger the atomizer 6 to start the atomization work.

During the long-term use of the atomizer 6, the atomized liquid and/or condensed liquid generated inside the atomizer 6 will generally flow into the air inlet channel 131 through the air inlet port 61 of the atomizer 6. Since the branch airway 15 is provided on the air inlet channel 131, the atomized liquid and/or condensed liquid generated inside the atomizer 6 can be prevented from penetrating into the pneumatic switch 2 through the air inlet channel 131. At the same time, the atomized liquid and/or condensed liquid deposited on the inner wall of the branch airway 15 can also be timely converged into the first liquid collecting tank 112, which can prevent the atomized liquid and/or condensed liquid deposited on the inner wall of the branch airway 15 from penetrating into the pneumatic switch 2. In this way, the atomized liquid and/or condensed liquid can effectively overcome the erosion/immersion of the pneumatic switch 2 by the atomized liquid and/or condensed liquid. In addition, the branch air channel 15 is provided on the air inlet channel 131, which not only reduces the bending degree of the air inlet channel 131 and improves the smoothness of air intake of the air inlet channel 131, but also the airflow path of the branch air channel 15 is shorter, so that the airflow of the branch air channel 15 is more stable and concentrated, and can provide a relatively stable airflow or air pressure change to the pneumatic switch 2, thereby improving the triggering sensitivity of the pneumatic switch 2.

Compared with the prior art, the air guide structure provided by the embodiment of the utility model is provided with an air guide component 1 that can be matched and installed on the atomizer 6, an air inlet hole 111 and an air inlet channel 131 connecting the air inlet hole 111 and the air inlet port 61 of the atomizer 6 are provided on the air guide component 1, a branch air channel 15 is provided on one side of the air guide channel, and a pneumatic switch 2 is provided at a position corresponding to the branch air channel 15 on the air guide component 1. During the long-term operation of the atomizer 6, since the branch air channel 15 is provided on the air inlet channel 131, the atomized liquid and/or condensed liquid generated inside the atomizer 6 can be prevented from penetrating into the pneumatic switch 2 through the air inlet channel 131, and the atomized liquid and/or condensed liquid deposited on the inner wall of the branch air channel 15 can also be timely converged into the first liquid collecting tank 112 below the branch air channel 15, which can prevent the atomized liquid and/or condensed liquid deposited on the inner wall of the branch air channel 15 from penetrating into the pneumatic switch 2. In this way, the defect that the atomized liquid and/or condensed liquid corrodes/immerses the pneumatic switch 2 and causes the pneumatic switch 2 to malfunction or be damaged can be effectively overcome. In addition, a branch airway 15 with a shorter airflow path is provided on the air inlet channel 131 to reduce the degree of airway bending, improve the smoothness of air intake, make the airflow or air pressure change in the branch airway 15 more stable, and improve the triggering sensitivity of the pneumatic switch 2.

Please further refer to Figures 1, 2 and 4. In some embodiments, the air guide component 1 is further provided with a sensing chamber 121 connected to the branch airway 15, and the pneumatic switch 2 is accommodated in the sensing chamber 121. In this embodiment, the air guide component 1 is further provided with a sensing chamber 121, which is connected to the air inlet channel 131 through the branch airway 15. It is only necessary to accommodate the pneumatic switch 2 in the sensing chamber 121. When airflow or air pressure changes in the branch airway 15, a negative pressure will be generated in the sensing chamber 121 to trigger the pneumatic switch 2 to start working, which is conducive to improving the sensitivity of the pneumatic switch 2 to be triggered. In addition, the setting height of the sensing chamber 121 is higher than the setting height of the branch airway 15, which is conducive to preventing the atomized liquid and/or condensed liquid from penetrating into the sensing chamber 121 and corroding/soaking the pneumatic switch 2.

Please further refer to FIG. 1 , FIG. 2 and FIG. 4 . In some embodiments, the air guide component 1 is further provided with a second liquid collecting tank 113 for collecting condensate. The second liquid collecting tank 113 is located in the sensing cavity 121. Below, the notch of the second liquid collecting tank 113 is connected to the sensing chamber 121, and the atomized liquid and/or condensed liquid deposited on the inner wall of the sensing chamber 121 can be promptly converged into the second liquid collecting tank 113, thereby preventing the atomized liquid and/or condensed liquid deposited on the inner wall of the sensing chamber 121 from corroding/soaking the pneumatic switch 2.

Please further refer to Figures 1, 2 and 4. In some embodiments, the air guide component 1 includes a base 11, a first sealing seat 12 provided on the base 11 and an air inlet pipe 13 provided on the base 11. The base 11 is provided with an air inlet hole 111 and a first liquid collecting tank 112. The first end of the air inlet pipe 13 is connected to the air inlet hole 111, and the second end of the air inlet pipe 13 is connected to the air inlet port 61 of the atomizer 6. The pneumatic switch 2 is installed on the first sealing seat 12, and the branch airway 1 The air inlet pipe 13 is arranged on the base 11 and/or the first sealing seat 12. The pipeline of the air inlet pipe 13 forms an air inlet channel 131. A diverter hole 132 connecting the air inlet channel 131 and the branch air channel 15 is opened on the side wall of the air inlet pipe 13. The diverter hole 132 is arranged near the second end of the air inlet pipe 13, so that there is a distance between the diverter hole 132 and the first liquid collecting tank 112 on the base 11. The accommodating space on the base 11 below the diverter hole 132 can be used to store the atomized liquid and/or the condensed liquid. In this embodiment, an air inlet hole 111 for introducing external air is provided on the base 11, and an air inlet pipe 13 connected to the air inlet hole 111 is vertically provided on the base 11, and the external air is guided to the air inlet port 61 of the atomizer 6 through the vertically extending air inlet pipe 13, so as to reduce the bending degree of the airway and improve the smoothness of air intake, and at the same time, a stable and reliable airflow or air pressure change is generated in the branch airway 15 connected to the diverter hole 132 on the side wall of the air inlet pipe 13, so as to improve the triggering sensitivity of the pneumatic switch 2. It should be noted that the first sealing seat 12 can be but is not limited to a silicone member or a rubber member. The branch airway 15 is provided on the base 11 and/or the first sealing seat 12, including the following three situations: first, the branch airway 15 can be provided on the base 11, second, the branch airway 15 can also be provided on the first sealing seat 12, and third, the branch airway 15 can also be provided on the base 11 and the first sealing seat 12, that is, the branch airway 15 is provided on the base 11 and the first sealing seat 12 at the same time. It can be understood that the first sealing seat 12 can be, but is not limited to, a silicone member or a rubber member.

Please further refer to FIG. 1, FIG. 2 and FIG. 4. In some embodiments, the base 11 is provided with a liquid storage tank 114 for storing atomized liquid and/or condensed liquid, and the liquid storage tank 114 is connected to the air inlet 61 of the atomizer 6. In this embodiment, the second end of the air inlet pipe 13 is spaced apart from the air inlet 61 of the atomizer 6 by a certain distance, and a branch airway 15 is provided on the air inlet pipe 13 near its second end. The flow hole 132 allows a spacing to exist between the diverter hole 132 and the first liquid collecting tank 112 on the base 11, thereby allowing the accommodating space on the base 11 below the diverter hole 132 to form a liquid storage tank 114 for storing atomized liquid and/or condensed liquid. The liquid storage tank 114 is connected to the air inlet 61 of the atomizer 6, so that the atomized liquid and/or condensed liquid generated inside the atomizer 6 can flow into the liquid storage tank 114 through the air inlet 61 of the atomizer 6, thereby preventing the atomized liquid and/or condensed liquid generated inside the atomizer 6 from flowing into the air inlet 111 along the air inlet pipe 13, thereby reducing the risk of leakage and contamination of the atomized liquid and/or condensed liquid.

Please further refer to FIG. 1 and FIG. 4 . In some embodiments, a liquid absorbing member 3 for absorbing atomized liquid and/or condensed liquid is provided in the liquid storage bin 114. The atomized liquid and/or condensed liquid in the liquid storage bin 114 can be absorbed by the liquid absorbing member 3, further reducing the risk of leakage and contamination of the atomized liquid and/or condensed liquid. It should be noted that the liquid absorbing member 3 can be, but is not limited to, liquid absorbing cotton or liquid absorbing fiber.

Please further refer to FIG. 1 and FIG. 4 . In some embodiments, the air guide assembly 1 further includes a circuit board 4 covering the first sealing seat 12. The circuit board 4 is placed horizontally, and the circuit board 4 can seal the inside of the air guide assembly 1. The pneumatic switch 2 is electrically connected to the circuit board 4, wherein the plug-in or patch of the pneumatic switch 2 is on the circuit board 4 facing the base 11, and the pins of the atomizer core 63 pass through the circuit board 4, which is conducive to shortening the airflow path of the branch airway 15, generating a stable and reliable airflow or air pressure change through the branch airway 15, and improving the triggering sensitivity of the pneumatic switch 2.

Please further refer to FIG. 1 . In some embodiments, a pressure relief hole 5 is provided on the circuit board 4 , and the pressure relief hole 5 is connected to the outside. When the atomizer is transported or carried, after the air inlet hole 111 on the air guide component 1 is closed, the air is exhausted through the pressure relief hole 5 to avoid the air guide component 1 being sealed inside and generating negative pressure, thereby erroneously triggering the pneumatic switch 2 and causing safety hazards.

Please further refer to Figures 1, 4 and 5. In some embodiments, the air guide assembly 1 further includes a second sealing seat 14 for matching with the bottom of the atomizer 6. The second sealing seat 14 is provided with a switching airway 141 for connecting the air inlet channel 131 with the air inlet 61 of the atomizer 6. In this embodiment, the second sealing seat 14 is provided with a switching airway 141 for connecting the air inlet channel 131 with the air inlet 61 of the atomizer 6, which facilitates the matching connection between the air guide assembly 1 and the bottom of the atomizer 6. In addition, when the second sealing seat 14 is matched with the bottom of the atomizer 6, the atomizer core 63 of the atomizer 6 can be supported and fixed on the second sealing seat 14. On the sealing seat 14, the transfer air channel 141 can connect the air inlet channel 131 with the air inlet 61 of the atomizing core 63, reduce the degree of air channel bending, shorten the air inlet path, and improve the smoothness of air inlet. It should be noted that the second sealing seat 14 can be but not limited to a silicone member or a rubber member.

Please further refer to FIG. 2 . In some embodiments, the diameter of the air inlet channel 131 gradually decreases along the flow direction of the air in the air inlet channel 131. Specifically, the air inlet channel 131 may be convex or conical, and the air flow passing through the air inlet channel 131 may be accelerated, so that a stable and reliable air flow or air pressure change is generated in the branch air channel 15 connected to the diverter hole 132 on the side wall of the air inlet pipe 13, thereby improving the sensitivity of the pneumatic switch 2 to be triggered.

Please further refer to Figures 1, 2 and 4. In some embodiments, the air inlet channel 131 extends longitudinally and the branch air channel 15 extends transversely, which helps to prevent the atomized liquid and/or condensed liquid in the air inlet channel 131 from flowing into the branch air channel 15.

Please refer to Figures 3, 4 and 5, the embodiment of the utility model further provides an atomizing device, the sol generating device includes an atomizer 6 for atomizing the atomized liquid to form an aerosol, a power supply device for supplying power to the atomizer 6, and an air guide structure provided in any of the above embodiments.
