However, since the airflow switch is usually arranged at the bottom of the atomization device, the airflow needs a long time to flow in the atomization air channel, which causes the sensing air channel to need a long time to generate airflow change, thereby affecting the sensitivity of the airflow switch.

[0049] To solve the above problems, the present application provides a suction port device and an atomization device, the sensing air channel is arranged on the suction port device to shorten the length of the sensing air channel and improve the sensitivity of the airflow switch.

[0050] Embodiment one,

[0051] Referring to Figures 1-4 As shown in the figure, the atomization device 100 provided by the present embodiment includes a housing assembly 10, a suction port assembly 20, an airflow switch 30, and an atomization assembly 40.

[0052] The housing assembly 10 is internally provided with a suction port cavity 11 and an atomization cavity 12, the suction port cavity 11 and the atomization cavity 12 are independent chambers, and the housing assembly 10 is provided with a suction port 13 in communication with the suction port cavity 11.

[0053] The suction port assembly 20 is arranged in the suction port cavity 11, and the suction port assembly 20 and the part of the housing assembly 10 provided with the suction port cavity 11 form a suction port through which the user can suck. The suction port assembly 20 is preferably made of soft material, such as food-grade silica gel. For example,Figure 3 , Figures 6-8 As shown, the nozzle assembly 20 is provided with a main sensing airway 24, a secondary sensing airway 25, and a nozzle airway 26. One end of the main sensing airway 24 is in fluid communication with the nozzle opening 13. An airflow switch 30 is located on the other side of the nozzle assembly 20 opposite to the nozzle opening 13, and the airflow switch 30 is in fluid communication with the other end of the main sensing airway 24. Thus, the main sensing airway 24 extends through the height direction of the nozzle assembly 20. Figure 3 (As shown in the Y-axis direction), the nozzle airway 26 is fluidly connected to the nozzle opening 13 and the atomizing chamber 12, and the atomizing assembly 40 is installed in the atomizing chamber 12. The nozzle airway 26 also extends through the height direction of the nozzle assembly 20. The secondary sensing airway 25 fluidly connects the main sensing airway 24 and the nozzle airway 25.

[0054] like Figure 2 and Figure 4 As shown, the atomizing device 100 provided in this application also includes an inner chamber 50, a display screen 60, a power supply unit 70, and a support assembly 17. The inner chamber 50 is installed inside the housing assembly 10 and fixedly mounted on the support assembly 17. A liquid storage chamber 110 is formed between the outer wall of the inner chamber 50 and the inner wall of the housing assembly 10. The liquid storage chamber 110 is used to store the atomizing matrix, which specifically refers to e-liquid. The display screen 60 has a ring structure and is installed against the inner wall of the inner chamber 50. The inner chamber 50 has two independent atomizing chambers 12 and energy storage chambers 14. The atomizing component 40 is installed in the atomizing chamber 12, and the power supply unit 70 is installed in the energy storage chamber 14. The power supply unit 70 can provide the electrical energy required for heating the atomizing component 40. It can be considered that the display screen 60, the atomizing chamber 12, and the energy storage chamber 14 are independent of each other inside the inner chamber 50 and do not interfere with each other. The liquid storage cavity 110 formed between the outer wall of the inner chamber 50 and the inner wall of the shell assembly 10 is also annular. In this embodiment, the inner chamber 50 and the shell assembly 10 are made of transparent material. On the one hand, the remaining amount of atomized matrix in the liquid storage cavity 110 can be observed. On the other hand, it is also convenient to observe the information displayed on the display screen 60, such as displaying different colors or displaying changing colors.

[0055] See Figure 4 As shown, the inner chamber 50 located inside the liquid storage chamber 110 is provided with a liquid inlet hole 51. The liquid inlet hole 51 connects the atomizing chamber 12 and the liquid storage chamber 110. The atomizing matrix stored in the liquid storage chamber 110 can enter the atomizing chamber 12 through the liquid inlet hole 51 to provide it to the atomizing assembly 40.

[0056] like Figure 4As shown, the atomization cavity 12 is further provided with a tube body 80 and a liquid storage member 16, the liquid storage member 16 is installed inside the tube body 80, the liquid storage member 16 is provided with an atomization air channel 161, the atomization assembly 40 is installed in the atomization air channel 161, and the atomization air channel 161 is in fluid communication with the suction air channel 26. The tube body 80 is provided with a liquid guide hole (not shown in the figure), the atomization substrate in the liquid storage cavity 110 enters the inside of the tube body 80 in sequence through the liquid inlet hole 51 and the liquid guide hole, and the liquid storage member 16 is usually made of fiber cotton material and can store the atomization substrate by adsorption and provide the stored atomization substrate to the atomization assembly 40.

[0057] Continuing to refer to Figure 4 As shown, the atomization assembly 40 includes an atomization tube 41, a liquid guide member 42, and a heating member 43, the liquid guide member 42 is a hollow columnar structure, the heating member 43 is installed on the inner wall of the liquid guide member 42, the liquid guide member 42 is installed in the inside of the atomization tube 41, the atomization tube 41 is installed in the atomization air channel 161, and the atomization tube 41 is coaxially arranged with the atomization air channel 161, the atomization tube 41 is provided with at least one opening 411, part of the liquid guide member 42 is exposed to the opening 411, and the atomization substrate entering the inside of the tube body 80 is transported to the liquid guide member 42 through the opening 411, and then the liquid guide member 42 adsorbs and wets the heating member 43 by capillary action. The heating member 43 is electrically connected with the power supply unit 70, and the heating member 43 provides the required electric energy by the power supply unit 70 to heat and atomize the atomization substrate to generate aerosol, and the aerosol enters the suction air channel 26 from the atomization air channel 161 and is output from the suction port 13 to provide the user.

[0058] As shown in Figure 2 , Figure 3 , Figure 6 and Figure 7 , the inner cartridge 50 is open on the side away from the support assembly 17, and the suction assembly 20 is provided with a first sealing ring 224 and a second sealing ring 225 on the side facing the inner cartridge 50, the first sealing ring 224 surrounds the outer periphery of the second sealing ring 225, and the first sealing ring 224 is in interference fit with the inner cavity of the shell assembly 10 to form a sealed liquid storage cavity 110, the tube body 80 is inserted into the outer surface of the second sealing ring 225, and the suction air channel 26 penetrates through the second sealing ring 225.

[0059] As shown in Figure 2As shown, the shell assembly 10 is also provided with an air inlet hole 15, and the atomization air channel 161 communicates with the air inlet hole 15. When a user sucks through the suction port 13, external air can enter the atomization air channel 161 through the air inlet hole 15 to form an airflow. At the same time, due to the suction action of the user at the suction port 13, the air in the main induction air channel 24 and the auxiliary induction air channel 25 is sucked away to generate a negative pressure (induction airflow). The airflow switch 30 senses the change in air pressure and generates an activation signal through the processor. The processor controls the heating element 43 to generate heat through the activation signal to heat the atomization substrate to generate aerosol. The aerosol is output from the suction port 13 along with the airflow through the atomization air channel 161 and the suction air channel 26.

[0060] It should be noted that when the user sucks through the suction port 13, the suction port 13 is sucked to make the air pressure inside the suction air channel 26 less than the air pressure outside the atomization device 100. The air pressure inside the main induction air channel 24 and the auxiliary induction air channel 25 that communicates with the suction air channel 26 is also less than the air pressure outside the atomization device 100, that is, they are all negative pressure channels. Therefore, the negative pressure air channel can be composed of the main induction air channel 24 pointing to the suction port 13, or sequentially composed of the main induction air channel 24, the auxiliary induction air channel 25, and the suction air channel 26 pointing to the suction port 13. Both can make the airflow switch 30 sense the change in airflow.

[0061] In this application, the main induction air channel 24 and the auxiliary induction air channel 25 are arranged on the suction assembly 20, and the airflow switch 30 is arranged on the other side of the suction assembly 20 away from the suction port 13. The main induction air channel 24 fluidically connects the airflow switch 30 and the suction port 13. At the same time, the auxiliary induction air channel 25 fluidically connects the main induction air channel 24 and the suction air channel 26. Compared with the related art in which the airflow switch 30 is arranged at the bottom of the atomization device 100 (the position where the air inlet hole 16 is arranged), the flow path of the induction airflow can be significantly shortened, the airflow switch 30 can quickly sense the change in air pressure, and the sensitivity of the airflow switch 30 can be improved.

[0062] During the process of outputting the aerosol from the suction air channel 26, condensate can be easily generated due to temperature changes. The condensate can flow back into the main induction air channel 24 under the action of its own gravity and further cause corrosion and damage to the airflow switch 30 or even self-activation. Or, after a puff, the rear section of the aerosol enters the air channels in the suction assembly 20, for example, the rear section of the aerosol enters the main induction air channel 24 and forms condensate when it cools down and falls to the airflow switch 30. Figure 2 and Figure 3As shown, the suction nozzle assembly 20 has an air guide slit 111 between the outer wall of the suction nozzle opening 13 and the cavity wall of the suction nozzle cavity 11. One end of the main sensing airway 24 can also be fluidly connected to the suction nozzle opening 13 through the air guide slit 111. The arrangement of the air guide slit 111 allows the sensing airflow to form an approximately tortuous flow path, which can effectively prevent condensate from flowing back into the main sensing airway 24. At the same time, by connecting the main sensing airway 24 and the suction nozzle opening 13 through the air guide slit 111, the user's mouth can completely cover the suction nozzle opening 13 when performing suction.

[0063] The air guide slit 111 can be considered as a gap formed between the outer wall of the nozzle assembly 20 facing the nozzle opening 13 and the cavity wall of the nozzle cavity 11, which ensures the communication between the main sensing airway 24 and the nozzle opening 13. In other embodiments, a groove can be provided on the outer wall of the nozzle assembly 20 facing the nozzle opening 13, or a groove can be provided on the cavity wall of the nozzle cavity 11, through which the air guide slit 111 is formed.

[0064] The main sensing airway 24 and the air guide slit 111 form the main flow path of the sensing airflow, and the main sensing airway 24 and the secondary sensing airway 25 form the secondary flow path of the sensing airflow. With prolonged use of the atomizing device 100, the air guide slit 111 may become clogged due to its small gap. Therefore, the flow of the sensing airflow can be ensured through the secondary flow path of the sensing airflow.

[0065] To connect the main sensing airway 24 with the auxiliary sensing airway 25, see [reference needed]. Figure 3 , Figures 5-7 As shown, the suction nozzle assembly 20 has a guide groove 215 on the outer wall facing the suction nozzle opening 13. The guide groove 215 can be considered as a notch provided on the outer wall of the suction nozzle assembly 20 facing the suction nozzle opening 13. The space enclosed by the guide groove 215 and the cavity wall of the suction nozzle cavity 11 conducts fluid through the main sensing airway 24 and the secondary sensing airway 25. Furthermore, this space conducts fluid through the main sensing airway 24 and the secondary sensing airway 25 to the air guide slit 111.

[0066] See Figures 5-7 As shown, the outer wall of the nozzle assembly 20 is also provided with a sealing protrusion 216 around its periphery. The sealing protrusion 216 cooperates with the cavity wall of the nozzle cavity 11 to seal. Along the height direction of the nozzle assembly 20, the projection of the guide groove 215, the projection of the air guide slit 111, and the projection of the end of the nozzle air passage 26 connected to the nozzle opening 13 overlap in the area enclosed by the projection of the sealing protrusion 216, thereby forming a sealed state between the area where the guide groove 215 and the air guide slit 111 are located, ensuring that the air guide slit 111 can be fluidly connected to the guide groove 215.

[0067] In the present application, the main induction air passage 24 and the auxiliary induction air passage 25 are parallel to each other, and in a preferred embodiment, the main induction air passage 24 and the auxiliary induction air passage 25 are parallel to the height direction of the mouthpiece assembly 20. Of course, the two can also be inclined or perpendicular to the height direction of the mouthpiece assembly 20. The parallel relationship between the main induction air passage 24 and the auxiliary induction air passage 25 allows a bending connection to be formed therebetween, which can further prevent the condensate from flowing back into the main induction air passage 24.

[0068] As shown in Figure 6 and Figure 7 , the main induction air passage 24 and the auxiliary induction air passage 25 share the same passage wall 217. Condensate is likely to be generated at the connection between the main induction air passage 24 and the auxiliary induction air passage 25. In the present embodiment, the portion of the passage wall 217 located on one side of the auxiliary induction air passage 25 is inclined, which can cause the condensate to flow back into the auxiliary induction air passage 25.

[0069] As shown in Figure 3 and Figure 6 , the mouthpiece assembly 20 further comprises a transition air passage 27 that penetrates the wall of the mouthpiece air passage 26. The main induction air passage 24 and the auxiliary induction air passage 25 are parallel to the axis of the mouthpiece port 11, and the axis of the mouthpiece port 11 is parallel to the height direction of the mouthpiece assembly 20. The transition air passage 27 fluidly connects the auxiliary induction air passage 25 and the mouthpiece air passage 26, so that the main induction air passage 24 and the mouthpiece air passage 26 are fluidly connected through the transition air passage 27 and the auxiliary induction air passage 25.

[0070] In the present embodiment, the transition air passage 27 and the auxiliary induction air passage 25 are formed in a bent shape. In a preferred embodiment, the transition air passage 27 is arranged along the X-axis direction as shown in Figure 3 , that is, the transition air passage 27 is perpendicular to the height direction of the mouthpiece assembly 20, so that the transition air passage 27 and the auxiliary induction air passage 25 form a right angle relationship, which can further prevent the condensate from flowing back.

[0071] Of course, in other embodiments, the transition air passage 27 and the auxiliary induction air passage 25 can also form an obtuse angle or an acute angle.

[0072] As shown in Figure 3 , Figure 6 and Figure 7 , the mouthpiece assembly 20 further comprises a liquid suction cavity 28 that is provided with a liquid suction member 23. The liquid suction cavity 28 is in communication with at least the mouthpiece air passage 26, and the liquid suction member 23 can adsorb the condensate flowing back from the mouthpiece air passage 26.

[0073] In the present application, the liquid suction cavity 28 is also in communication with the auxiliary induction air passage 25. In this way, even the condensate flowing back into the auxiliary induction air passage 25 from the transition air passage 27 can be adsorbed by the liquid suction member 23.

[0074] In some embodiments, the liquid suction cavity 28 is arranged around the suction nozzle air channel 26 and is in communication with the suction nozzle air channel 26, the liquid suction member 23 is provided with a gas guide channel 231 penetratingly, and the suction nozzle air channel 26 penetrates the gas guide channel 231 to ensure that the condensate flowing back from the air channel wall of the suction nozzle air channel 26 can be completely absorbed by the liquid suction member 23.

[0075] To facilitate the installation of the air flow switch 30, the suction nozzle assembly 20 is further provided with a receiving groove 29 on the side away from the suction nozzle port 13, the air flow switch 30 is installed in the receiving groove 29, and the other end of the main induction air channel 24 is in fluid communication with the receiving groove 29.

Taking the drawings used in the above-mentioned embodiments as an example, the mouthpiece device provided in this embodiment comprises a shell assembly 10 and a mouthpiece assembly 20.

[0091] The mouth assembly 20 is arranged in the mouth cavity 11, and the mouth assembly 20 and the housing assembly 10 form a mouth for the user to perform a suction action.

The mouth assembly 20 is provided with a main induction air channel 24, a secondary induction air channel 25, and a mouth air channel 26. One end of the main induction air channel 24 is in fluid communication with the mouth opening 13. In the embodiment, the airflow switch 30 is arranged in the main machine of the atomization device and located on the other side of the mouth assembly 20 away from the mouth opening 13.

The liquid suction member 23 is provided with a gas guiding air channel 231, and the nozzle air channel 26 penetrates the gas guiding air channel 231, so as to ensure that the condensed liquid backflowing from the air channel wall of the nozzle air channel 26 can be completely absorbed by the liquid suction member 23.
