[0044] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0045] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0046] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0047] The atomizing device can atomize water to humidify the air, or it can atomize an atomizing liquid to generate an aerosol. The atomizing liquid can be a liquid or a paste-like fragrance, etc. The aerosol produced after atomization can purify or improve air quality. The atomizing liquid can also be plant leaves, tobacco paste, e-liquid, etc., and the aerosol produced after atomization can be inhaled by the user. This application does not limit the objects atomized by the atomizing component; the specific selection can be based on actual needs. In the following embodiments, the atomizing component is described using the atomization of plant leaves, tobacco paste, e-liquid, etc., to generate an aerosol as an example. For simplicity, plant leaves, tobacco paste, e-liquid, etc., are collectively referred to as the atomizing matrix.

[0048] In related technologies, the atomizing component in the atomizing device is connected to an airflow switch, which is activated by a sensing airway. The atomizing device also has interconnected mouthpiece and atomizing airways. The sensing airway is connected to the atomizing airway, and the atomizing component is located within the atomizing airway. When the user draws air through the mouthpiece, outside air enters the atomizing airway. The sensing airway detects this airflow change and generates a start signal to activate the atomizing component, thereby heating and atomizing the atomizing substrate to produce an aerosol, thus preventing the coil from burning. However, since the airflow switch is usually located at the bottom of the atomizing device, the airflow takes a relatively long time to flow within the atomizing airway, resulting in a longer time for the sensing airway to register the airflow change. This affects the sensitivity of the airflow switch.

[0049] To address the aforementioned issues, this application provides a suction nozzle device and an atomizing device, wherein the sensing airway is disposed on the suction nozzle device to shorten the length of the sensing airway and improve the sensitivity of the airflow switch.

[0050] Example 1

[0051] See Figures 1-4 As shown, the atomizing device 100 provided in this embodiment includes a housing assembly 10, a mouthpiece assembly 20, an airflow switch 30, and an atomizing assembly 40.

[0052] The housing assembly 10 has a mouthpiece chamber 11 and an atomizing chamber 12 inside. The mouthpiece chamber 11 and the atomizing chamber 12 are independent chambers. The housing assembly 10 has a mouthpiece opening 13 that communicates with the mouthpiece chamber 11.

[0053] The suction nozzle assembly 20 is disposed in the suction nozzle cavity 11. The suction nozzle assembly 20 and the portion of the housing assembly 10 disposed in the suction nozzle cavity 11 together form the suction nozzle, through which the user can perform suction. The suction nozzle assembly 20 is preferably made of a soft material, such as food-grade silicone. 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 atomizing chamber 12 also includes a tube 80 and a liquid storage component 16. The liquid storage component 16 is installed inside the tube 80 and has an atomizing air passage 161. The atomizing assembly 40 is installed in the atomizing air passage 161, and the atomizing air passage 161 is in fluid communication with the nozzle air passage 26. The tube 80 has a liquid guiding hole (not shown in the figure). The atomizing matrix in the liquid storage chamber 110 enters the interior of the tube 80 through the liquid inlet 51 and the liquid guiding hole in sequence. The liquid storage component 16 is usually made of fiber cotton and can store the atomizing matrix by adsorption and provide the stored atomizing matrix to the atomizing assembly 40.

[0057] See also Figure 4 As shown, the atomizing assembly 40 includes an atomizing tube 41, a liquid guide 42, and a heating element 43. The liquid guide 42 is a hollow cylindrical structure. The heating element 43 is fitted onto the inner wall of the liquid guide 42. The liquid guide 42 is installed inside the atomizing tube 41, which is installed in the atomizing air passage 161. The atomizing tube 41 and the atomizing air passage 161 are coaxially arranged. At least one opening 411 is provided on the atomizing tube 41, and part of the liquid guide 42 is exposed to the opening 411. The atomizing matrix that enters the tube body 80 is transported to the liquid guide 42 through the opening 411. The liquid guide 42 then adsorbs and wets the heating element 43 by capillary action. The heating element 43 is electrically connected to the power supply unit 70, which provides the electrical energy required for heating so as to heat and atomize the atomizing matrix to generate an aerosol. The aerosol enters the mouthpiece air passage 26 through the atomizing air passage 161 and is output to the user through the mouthpiece port 13.

[0058] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the inner chamber 50 has an open structure on the side away from the support assembly 17, while the nozzle assembly 20 has a first sealing ring 224 and a second sealing ring 225 protruding on the side facing the inner chamber 50. The first sealing ring 224 surrounds the outer periphery of the second sealing ring 225. The first sealing ring 224 is press-fitted with the inner cavity of the housing assembly 10 to form a sealed liquid storage chamber 110. The tube body 80 is inserted into the outer surface of the second sealing ring 225, and the nozzle air passage 26 passes through the second sealing ring 225.

[0059] like Figure 2As shown, the housing assembly 10 is also provided with an air inlet 15, and the atomizing air passage 161 is connected to the air inlet 15. The user draws air through the mouthpiece 13, and the external air can enter the atomizing air passage 161 through the air inlet 15 to form an airflow. At the same time, due to the user's drawing action at the mouthpiece 13, the air in the main sensing air passage 24 and the secondary sensing air passage 25 is drawn away, generating a negative pressure (sensing airflow). The airflow switch 30 senses the change in air pressure and generates a start signal through the processor. The processor controls the heating element 43 to generate heat through the start signal to heat the atomizing matrix to generate aerosol. The aerosol is carried by the airflow through the atomizing air passage 161 and the mouthpiece air passage 26 and output from the mouthpiece 13.

[0060] It should be noted that when the user draws air through the mouthpiece 13, the air pressure inside the mouthpiece airway 26 is lower than the air pressure outside the atomizing device 100 because the mouthpiece 13 is being drawn in. The air pressure inside the main sensing airway 24 and the auxiliary sensing airway 25, which are connected to the mouthpiece airway 26, is also lower than the air pressure outside the atomizing device 100, i.e., both are negative pressure channels. The negative pressure airway can be formed by the main sensing airway 24 pointing towards the mouthpiece 13, or it can be formed by the main sensing airway 24, the auxiliary sensing airway 25, and the mouthpiece airway 26 pointing towards the mouthpiece 13 in sequence. In both cases, the airflow switch 30 can sense the change in airflow.

[0061] In this application, the main sensing airway 24 and the secondary sensing airway 25 are disposed on the nozzle assembly 20, and the airflow switch 30 is disposed on the other side of the nozzle assembly 20 opposite to the nozzle opening 13. The main sensing airway 24 connects the airflow switch 30 with the nozzle opening 13, while the secondary sensing airway 25 connects the main sensing airway 24 with the nozzle airway 26. Compared with the related technology in which the airflow switch 30 is disposed at the bottom of the atomizing device 100 (the position where the air inlet 16 is located), the flow path of the sensing airflow can be significantly shortened, and the airflow switch 30 can quickly sense changes in air pressure, thereby improving the sensitivity of the airflow switch 30.

[0062] During the aerosol output from the nozzle airway 26, condensation can easily form due to temperature changes. This condensation can flow back into the main sensing airway 24 under its own gravity, further leading to corrosion and damage to the airflow switch 30, or even automatic activation. Alternatively, after one suction cycle, the remaining aerosol may enter various airways within the nozzle assembly 20, for example, the remaining aerosol may enter the main sensing airway 24, where it cools and condenses, falling into the airflow switch 30. See also... 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 this application, the main sensing airway 24 and the auxiliary sensing airway 25 are parallel to each other. In a preferred embodiment, the main sensing airway 24 and the auxiliary sensing airway 25 are parallel to the height direction of the nozzle assembly 20. Of course, they can also be inclined or perpendicular to the height direction of the nozzle assembly 20. The parallel positional relationship allows a bend to be formed between the main sensing airway 24 and the auxiliary sensing airway 25, which can further prevent condensate from flowing back into the main sensing airway 24.

[0068] like Figure 6 and Figure 7 As shown, the main sensing airway 24 and the secondary sensing airway 25 share the same channel wall 217. In this embodiment, aerosols are prone to generate condensate at the connection between the main sensing airway 24 and the secondary sensing airway 25. In this embodiment, a portion of the channel wall 217 located on one side of the secondary sensing airway 25 is inclined so that the condensate can flow back into the secondary sensing airway 25.

[0069] See Figure 3 and Figure 6 As shown, the nozzle assembly 20 is also provided with a transition airway 27, which penetrates the wall of the nozzle airway 26. The main sensing airway 24 and the auxiliary sensing airway 25 are both parallel to the axis of the nozzle opening 11. The axis of the nozzle opening 11 is parallel to the height direction of the nozzle assembly 20. The transition airway 27 connects the auxiliary sensing airway 25 and the nozzle airway 26, thereby connecting the main sensing airway 24 and the nozzle airway 26 through the transition airway 27 and the auxiliary sensing airway 25.

[0070] In this embodiment, the transition airway 27 and the secondary sensing airway 25 are formed in a bent shape. In a preferred embodiment, the transition airway 27 is along... Figure 3 The X-axis direction is set as shown, that is, the transition air passage 27 is perpendicular to the height direction of the nozzle assembly 20, so that the transition air passage 27 and the secondary sensing air passage 25 are at right angles to further prevent the condensate from flowing back.

[0071] Of course, in other embodiments, the transition airway 27 and the secondary sensing airway 25 may also be at an obtuse or acute angle.

[0072] See Figure 3 , Figure 6 and Figure 7 As shown, the nozzle assembly 20 is also provided with a liquid suction chamber 28, and the liquid suction chamber 28 is provided with a liquid suction element 23. The liquid suction chamber 28 is at least connected to the nozzle air passage 26. The liquid suction element 23 can adsorb the condensate flowing back from the nozzle air passage 26.

[0073] In this application, the suction chamber 28 is also connected to the secondary sensing airway 25. This arrangement allows the suction element 23 to absorb even the condensate that flows back from the transition airway 27 to the secondary sensing airway 25.

[0074] In some embodiments, the suction chamber 28 surrounds the suction nozzle air passage 26 and is connected to the suction nozzle air passage 26. The suction member 23 is provided with a through air passage 231, and the suction nozzle air passage 26 passes through the through air passage 231 to ensure that the condensate flowing back from the air passage wall of the suction nozzle air passage 26 can be completely absorbed by the suction member 23.

[0075] To facilitate the installation of the airflow switch 30, the nozzle assembly 20 is provided with a receiving groove 29 on the side away from the nozzle opening 13. The airflow switch 30 is installed in the receiving groove 29, and the other end of the main sensing air passage 24 is in fluid communication with the receiving groove 29.

[0076] See Figure 7 As shown, the suction nozzle assembly 20 includes a first suction nozzle 21 and a second suction nozzle 22. The first suction nozzle 21 and the second suction nozzle 22 are detachably connected, and the first suction nozzle 21 is closer to the suction nozzle opening 13. The liquid suction member 23 is installed between the first suction nozzle 21 and the second suction nozzle 22.

[0077] The first suction nozzle 21 is provided with a first main sensing airway 211 and a first suction airway 212 extending through the height of the suction nozzle assembly 10. The second suction nozzle 22 is provided with a second main sensing airway 221 and a second suction airway 222 extending through the height of the suction nozzle. The first suction nozzle 21 is also provided with a first liquid suction groove 213 on the side facing the second suction nozzle 22, and the second suction nozzle 22 is also provided with a second liquid suction groove 223 on the side facing the first suction nozzle 21. The auxiliary sensing airway 25 is provided on the first suction nozzle 21. The guide groove 215 is provided on the outer wall of the first suction nozzle 21 facing the suction nozzle opening 13. The auxiliary sensing airway 25 communicates with the guide groove 215 and the first liquid suction groove 213. The receiving groove 29 is provided on the side of the second suction nozzle 22 facing away from the first suction nozzle 21, and the second main sensing airway 221 passes through the receiving groove 29. After the first suction nozzle 21 and the second suction nozzle 22 are connected, the first main sensing airway 211 and the second main sensing airway 221 communicate with each other to form the main sensing airway 24. The first suction nozzle airway 212 and the second suction nozzle airway 222 communicate with each other to form the suction nozzle airway 26. The first liquid suction groove 213 and the second liquid suction groove 223 form the mounting cavity 28, and the liquid suction component 23 is installed in the first liquid suction groove 213 and the second liquid suction groove 223. The separate design of the first suction nozzle 21 and the second suction nozzle 22 facilitates the installation of the liquid suction component 23, simplifies the structure, and is beneficial to product manufacturing.

[0078] In this embodiment, the first suction nozzle 21 is provided with a transition groove 214 on the side facing the second suction nozzle 22. The transition groove 214 is connected to the first liquid suction groove 213. In a preferred embodiment, the transition groove 214 is formed at the bottom of the first liquid suction groove 213.

[0080] This application also provides an atomizing device. The difference between the atomizing device provided in this embodiment and that in Embodiment 1 is that the housing assembly is composed of a mouthpiece housing and an atomizing housing. The mouthpiece cavity is disposed inside the mouthpiece housing, and the atomizing cavity is disposed inside the atomizing housing. The mouthpiece housing and the atomizing housing are detachably connected. Furthermore, the first mouthpiece in the mouthpiece assembly is disposed in the mouthpiece cavity, and the first mouthpiece and the mouthpiece housing form a mouthpiece device. The second mouthpiece is disposed inside the atomizing housing. The atomizing assembly is disposed in the atomizing cavity and forms an atomizing host. The liquid suction element can be disposed on the first mouthpiece or on the second mouthpiece. In other words, the mouthpiece device and the atomizing host are detachably connected to form the atomizing device.

[0083] The suction nozzle assembly 20 is disposed in the suction nozzle cavity 11. The suction nozzle assembly 20 and the suction nozzle shell together form a suction nozzle, through which the user can perform suction. The suction nozzle assembly 20 is preferably made of a soft material, such as food-grade silicone. 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.

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.

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.

[0084] In this embodiment, see Figure 7As shown, the nozzle assembly 20 includes a first nozzle component 21 and a second nozzle component 22. The first nozzle component 21 and the second nozzle component 22 are detachably connected, and the first nozzle component 21 is closer to the nozzle opening 13. The liquid suction component 23 is installed between the first nozzle component 21 and the second nozzle component 22. The first nozzle component 21 is disposed in the nozzle cavity 11, and the second nozzle component 22 is disposed inside the atomizing shell.

[0085] The first suction nozzle 21 is provided with a first main sensing airway 211 and a first suction airway 212 extending through the height of the suction nozzle assembly 10. The second suction nozzle 22 is provided with a second main sensing airway 221 and a second suction airway 222 extending through the height of the suction nozzle. The first suction nozzle 21 is also provided with a first liquid suction groove 213 on the side facing the second suction nozzle 22, and the second suction nozzle 22 is also provided with a second liquid suction groove 223 on the side facing the first suction nozzle 21.

The auxiliary sensing airway 25 communicates with the guide groove 215 and the first liquid suction groove 213. The receiving groove 29 is provided on the side of the second suction nozzle 22 facing away from the first suction nozzle 21, and the second main sensing airway 221 passes through the receiving groove 29. After the first suction nozzle 21 and the second suction nozzle 22 are connected, the first main sensing airway 211 and the second main sensing airway 221 communicate with each other to form the main sensing airway 24. The first suction nozzle airway 212 and the second suction nozzle airway 222 communicate with each other to form the suction nozzle airway 26. The first liquid suction groove 213 and the second liquid suction groove 223 form the mounting cavity 28, and the liquid suction component 23 is installed in the first liquid suction groove 213 and the second liquid suction groove 223.

[0086] In this embodiment, the first suction nozzle 21 is provided with a transition groove 214 on the side facing the second suction nozzle 22.

[0087] Example 3

[0088] This application also provides a suction nozzle device, which can be applied to the atomizing device in the above embodiments, or used as a suction nozzle device independent of the atomizing device, so as to be applied to an atomizing device of any composition. Taking the drawings used in the above embodiments as an example, the suction nozzle device provided in this embodiment includes a housing assembly 10 and a suction nozzle assembly 20.

[0089] The housing assembly 10 has a mouthpiece cavity 11. In this embodiment, the housing assembly specifically refers to the housing portion forming the mouthpiece device, which only has the mouthpiece cavity 11. The housing assembly 10 has a mouthpiece opening 13 that communicates with the mouthpiece cavity 11. This housing assembly 10 can be connected to the housing of the rest of the atomizing device 100.

[0090] In some embodiments, the housing assembly 10 may also extend to form a housing for mounting the rest of the atomizing device 100, so as to form an integral structure with the rest of the housing of the atomizing device 100.

[0091] The mouthpiece assembly 20 is disposed in the mouthpiece cavity 11. The mouthpiece assembly 20 and the housing assembly 10 form a mouthpiece, which allows the user to perform a suction action. The mouthpiece assembly 20 is preferably made of a soft material, such as food-grade silicone. The mouthpiece assembly 20 has a main sensing airway 24, a secondary sensing airway 25, and a mouthpiece airway 26. One end of the main sensing airway 24 is fluidly connected to the mouthpiece opening 13. In this embodiment, the airflow switch 30 is disposed in the main unit of the atomizing device and located on the side of the mouthpiece assembly 20 away from the mouthpiece opening 13. The airflow switch 30 is fluidly connected to the other end of the main sensing airway 24, so the main sensing airway 24 extends through the height direction of the mouthpiece assembly 20. The mouthpiece airway 26 is fluidly connected to the mouthpiece opening 13 and the atomizing chamber 12. The atomizing assembly 40 is installed in the atomizing chamber 12, and the mouthpiece airway 26 also extends through the height direction of the mouthpiece assembly 20. The secondary sensing airway 25 fluidly connects the main sensing airway 24 and the mouthpiece airway 25.

[0092] After assembling the nozzle device provided in this application with the remaining structures of the atomizing device, for example, after assembling it with the atomizing component 40, the aerosol generated by the atomizing component 40 heating and atomizing the atomizing matrix can be output through the nozzle air passage 26. However, during the outflow of the aerosol, condensate will be generated due to temperature changes. This condensate can flow back into the main sensing air passage 24 under its own gravity, which may further lead to corrosion and damage of the airflow switch 30 or even self-restart. To address this, an air guide slit 111 is provided between the outer wall of the nozzle component 20 facing the nozzle opening 13 and the cavity wall of the nozzle cavity 11. One end of the main sensing air passage 24 is fluidly connected to the nozzle opening 13 through the air guide slit 111. The provision 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 air passage 24.

[0093] In this application, the main sensing airway 24 and the secondary sensing airway 25 are parallel to each other. In a preferred embodiment, the main sensing airway 24 and the secondary sensing airway 25 are parallel to the height direction of the nozzle assembly 20. In order to connect the main sensing airway 24 and the secondary sensing airway 25, a guide groove 215 is provided on the outer wall of the nozzle assembly 20 facing the nozzle opening 13. The guide groove 215 can be considered as a notch provided on the outer wall of the nozzle assembly 20 facing the nozzle opening 13. The guide groove 215 connects the main sensing airway 24 and the secondary sensing airway 25, and the guide groove 215 conducts fluid through the main sensing airway 24, the secondary sensing airway 25 and the air guide slit 111.

[0094] 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.

[0095] The nozzle assembly 20 is also provided with a transition air passage 27. The main sensing air passage 24 and the auxiliary sensing air passage 25 are both parallel to the axis of the nozzle opening 11. The axis of the nozzle opening 11 is parallel to the height direction of the nozzle assembly 20. The transition air passage 27 connects the auxiliary sensing air passage 25 and the nozzle air passage 26, thereby connecting the main sensing air passage 24 and the nozzle air passage 26. The transition air passage 27 and the auxiliary sensing air passage 25 are formed into a bent shape to further prevent the condensate from flowing back.

[0096] The nozzle assembly 20 is also provided with a liquid suction chamber 28, which is provided with a liquid suction element 23. The liquid suction chamber 28 is at least connected to the nozzle air passage 26. The liquid suction element 23 can adsorb the condensate flowing back from the nozzle air passage 26.

[0097] In this application, the suction chamber 28 is also connected to the secondary sensing airway 25. This arrangement allows the suction element 23 to absorb even the condensate that flows back from the transition airway 27 to the secondary sensing airway 25.

[0098] In some embodiments, the suction chamber 28 surrounds the suction nozzle air passage 26 and is connected to the suction nozzle air passage 26. The suction member 23 is provided with a through air passage 231, and the suction nozzle air passage 26 passes through the through air passage 231 to ensure that the condensate flowing back from the air passage wall of the suction nozzle air passage 26 can be completely absorbed by the suction member 23.

[0099] To facilitate the installation of the airflow switch 30, the nozzle assembly 20 is provided with a receiving groove 29 on the side away from the nozzle opening 13. The airflow switch 30 is installed in the receiving groove 29, and the other end of the main sensing air passage 24 is in fluid communication with the receiving groove 29.

[0100] In this application, the suction nozzle assembly 20 includes a first suction nozzle 21 and a second suction nozzle 22. The first suction nozzle 21 and the second suction nozzle 22 are connected to each other, and the first suction nozzle 21 is closer to the suction nozzle opening 13. The liquid suction member 23 is installed between the first suction nozzle 21 and the second suction nozzle 22.

[0101] The first suction nozzle 21 is provided with a first main sensing airway 211 and a first suction airway 212 extending through the height of the suction nozzle assembly 10. The second suction nozzle 22 is provided with a second main sensing airway 222 and a second suction airway 222 extending through the height of the suction nozzle. The first suction nozzle 21 is also provided with a first liquid suction groove 213 on the side facing the second suction nozzle 22, and the second suction nozzle 22 is also provided with a second liquid suction groove 223 on the side facing the first suction nozzle 21. The auxiliary sensing airway 25 is provided on the first suction nozzle 21. The guide groove 215 is provided on the outer wall of the first suction nozzle 21 facing the suction nozzle opening 13. The auxiliary sensing airway 25 communicates with the guide groove 215 and the first liquid suction groove 213. The receiving groove 29 is provided on the side of the second suction nozzle 22 facing away from the first suction nozzle 21, and the second main sensing airway 221 passes through the receiving groove 29. After the first suction nozzle 21 and the second suction nozzle 22 are connected, the first main sensing airway 211 and the second main sensing airway 221 communicate with each other to form the main sensing airway 24. The first suction nozzle airway 212 and the second suction nozzle airway 222 communicate with each other to form the suction nozzle airway 26. The first liquid suction groove 213 and the second liquid suction groove 223 form the mounting cavity 28, and the liquid suction component 23 is installed in the first liquid suction groove 213 and the second liquid suction groove 223. The separate design of the first suction nozzle 21 and the second suction nozzle 22 facilitates the installation of the liquid suction component 23, simplifies the structure, and is beneficial to product manufacturing.

[0102] In this embodiment, the first suction nozzle 21 is provided with a transition groove 214 on the side facing the second suction nozzle 22. The transition groove 214 is connected to the first liquid suction groove 213. In a preferred embodiment, the transition groove 214 is formed at the bottom of the first liquid suction groove 213. After the liquid suction member 23 is installed in the first liquid suction groove 213 and the second liquid suction groove 223, the liquid suction member 23 and the transition groove 214 cooperate to form a transition air passage 27.

[0103] In summary, the nozzle device and atomizing device provided in this application have a main sensing airway and a secondary sensing airway on the nozzle assembly, and an airflow switch on the side of the nozzle assembly away from the nozzle opening. The main sensing airway connects the airflow switch to the fluid at the nozzle opening, while the secondary sensing airway connects the main sensing airway to the fluid at the nozzle airway. Compared with the related technology where the airflow switch is located at the bottom of the atomizing device, the flow path of the sensing airflow can be significantly shortened, and the airflow switch can quickly sense the sensing airflow, thereby improving the sensitivity of the airflow switch.
