[0041] 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.

[0042] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0043] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the objects being described and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0044] Atomizing devices typically consist of a liquid reservoir and an atomizing core assembly. The liquid reservoir contains a storage chamber for storing the atomizing matrix. The atomizing core assembly is installed inside the storage chamber and also includes an atomization channel. Below the liquid reservoir is an airflow support, which has at least one sensing air channel connected to the atomization channel. An airflow sensor is mounted on the airflow support. When using the atomizing device, the user draws air through the sensing channel to the atomization channel. During this drawing process, the airflow sensor detects changes in air pressure flowing through the sensing channel, thereby controlling the operation of the atomizing core assembly.

[0045] In the aforementioned atomizing device, the air path support occupies a large space, resulting in a large overall size of the atomizing device, which is inconvenient for users and thus affects the user experience.

[0046] To address the aforementioned issues, this application provides an atomizing device in which the air duct component is embedded in the mounting groove at the bottom of the liquid storage tank, thereby reducing the space required for the air duct component and reducing the overall size of the atomizing device, making it easier for users to use and improving the user experience.

[0047] As shown in Figures 1-13, the atomizing device 100 provided in this application includes a liquid storage chamber 10, an atomizing core assembly 20, an air passage component 30, and an airflow sensor 40.

[0048] The liquid storage tank 10 is provided with a liquid storage cavity 101, which is used to store the atomizing matrix. The atomizing matrix can be heated by the atomizing core assembly 20 to generate an aerosol. One end of the liquid storage tank 10 is provided with a mounting groove 121, which communicates with the liquid storage cavity 101.

[0049] The atomizing core assembly 20 is disposed inside the liquid storage chamber 101. The atomizing core assembly forms an atomizing channel 211, which is connected to the mounting groove 121.

[0050] In this embodiment, a liquid storage component 102 is provided inside the liquid storage chamber 101. The liquid storage component 102 is made of fiber cotton material. The atomizing matrix is ​​usually in liquid form and can be stored by adsorption through the liquid storage component 102.

[0051] In one embodiment, an aerosol channel 1021 may be provided in the liquid storage component 102, and the atomizing core assembly 20 is disposed in the aerosol channel 1021.

[0052] The air passage 30 is embedded inside the mounting groove 121, as shown in Figures 2-4, 6, 7 and 10-12. The air passage 30 is also provided with an air intake channel 32 and a sensing channel 33 through it, and the air intake channel 32 and the sensing channel 33 are connected to the atomization channel 211.

[0053] When the user uses this atomizing device, the external atmosphere can enter the atomizing channel 211 through the air intake channel 32. Due to the flow of gas, the sensing channel 33 generates negative pressure. The airflow sensor 40 is installed on the air passage component 30. The airflow sensor 40 is used to sense the change in air pressure signal of the sensing channel 33 and output an electrical signal to the atomizing device 100 to control the operation of the atomizing core assembly 20, thereby heating the atomizing matrix to generate aerosol. The aerosol is then output through the aerosol channel 1021.

[0054] During the output process, aerosols are prone to condensation and backflow, with condensate or incompletely atomized atomized matrix flowing back through the atomization channel 211. In related atomization devices, the atomization channel 211 and the air intake channel 32 are at least coaxial, causing the aerosol to flow back through the air intake channel 32 to the outer surface of the atomization device 100, affecting the product's appearance. Therefore, in this embodiment, the air intake channel 32, the sensing channel 33, and the atomization channel 211 are offset from each other in the axial direction, preventing condensate or incompletely atomized matrix from flowing back into the air intake channel 32 and the sensing channel 33.

[0055] In the above embodiments, the air passage component 30, which is provided with the air inlet channel 32 and the sensing channel 33, is installed in the mounting groove 121 at one end of the liquid storage tank 10. This can save the space for setting up the air passage structure, thereby reducing the internal structural layout space of the atomizing device product, further reducing the overall volume of the atomizing device 100, which is beneficial to users and improves the user experience.

[0056] In this embodiment, the air duct component 30 and the bottom of the mounting groove 121 are spaced apart to form an air intake chamber 122. The air intake chamber 122 is connected to the air intake channel 32, the sensing channel 33 and the atomizing channel 211. After entering through the air intake channel 32, the external atmosphere first enters the air intake chamber 122. Due to the airflow, the sensing channel 33 generates a pressure change, which is sensed by the airflow sensor 40 to control the atomizing core assembly 20 to work. The aerosol generated by the atomizing core assembly 20 is output through the atomizing channel 211 under the action of the airflow.

[0057] In order to enable the air passage component 30 installed in the mounting groove 121 to form an air intake chamber 122 with the bottom of the mounting groove 121, as shown in FIG9, a limiting part 123 is also provided in the mounting groove 121. The limiting part 123 is used to limit the air passage component 30 so that the air passage component 30 and the bottom of the mounting groove 121 form an air intake chamber 122 with the gap.

[0058] In one embodiment, the limiting part 123 is at least one limiting block 1231 disposed on the bottom and / or sidewall of the mounting groove 121, and the air passage 30 abuts against the limiting block 1231 on the side opposite to the receiving groove 31, thereby forming an air inlet chamber 122 between the air passage 30 and the bottom of the mounting groove 121.

[0059] In this embodiment, two limiting blocks 1231 are provided between the bottom of the mounting groove 121 and / or the side wall of the groove, forming a stable support with the air passage component 30.

[0060] To facilitate the mutual misalignment of the air intake channel 32, the sensing channel 33, and the atomizing channel 211 in the axial direction, as shown in Figure 9, the air intake cavity 122 has a first space 1221 and a second space 1222 connected together. The first space 1221 is positioned corresponding to and connected to the atomizing channel 211, and the second space 1222 is positioned corresponding to and connected to the air intake channel 32 and the sensing channel 33, thereby making the air intake cavity 122 form an irregular structure.

[0061] In this embodiment, the shape of the mounting groove 121 is the same as the shape of the air intake chamber 122. To accommodate this shape, and since the atomizing channel 211, the air intake channel 32, and the sensing channel 33 are on different axes, to prevent the atomizing channel 211 from connecting to the outside through the mounting groove 121, as shown in Figures 6, 7, and 10-12, the air passage component 30 includes a body portion 34 and a protrusion 35. The protrusion 35 protrudes from the periphery of the body portion 34, and the air intake channel 32 and the sensing channel 33 are disposed through the body portion 34 along the thickness direction of the body portion 34. A first space 1221 is formed between the body portion 34 and the bottom of the mounting groove 121, and a second space 122 is formed between the protrusion 35 and the air intake end of the atomizing channel 211. The protrusion 35 can block the atomizing channel 211.

[0062] As shown in Figures 3, 7, and 11, the air passage 30 has a receiving groove 31 on the side facing away from the mounting groove 121, and the airflow sensor 40 is installed in the receiving groove 31. As shown in Figures 2-4, 6, 7, and 10-12, the sensing channel 33 is connected to the receiving groove 31, so that the sensing channel 33 can be connected to the airflow sensor 40.

[0063] Thus, the condensate or incompletely atomized atomized matrix generated by aerosol condensation will flow back into the air intake chamber 122 through the atomization channel 211. In related technologies, the backflowing condensate or incompletely atomized atomized matrix can flow back into the airflow sensor 40 through the sensing channel 33, causing corrosion and other damage to the airflow sensor 40. To avoid this problem, in this embodiment, a first guide post 331 is provided on the side of the air passage 30 facing the mounting groove 121. The sensing channel 33 is formed inside the first guide post 331, and the first guide post 331 is a columnar structure protruding from the side of the air passage 30 facing the mounting groove 121 towards the bottom of the mounting groove 121. Since the first guide post 331 is a structure protruding from the air passage 30, the condensate or incompletely atomized atomized matrix can be collected in the air intake chamber 122.

[0064] Correspondingly, condensate or incompletely atomized atomized matrix, after flowing back through the air inlet channel 32, will flow through the air guide hole 531 to the outer surface of the atomizing device 100, affecting the appearance of the product surface. Therefore, a second guide post 321 is also provided on the side of the air duct 30 facing the mounting groove 121, and the air inlet channel 32 is formed inside the second guide post 321. Similarly, since the second guide post 321 is a columnar structure protruding from the side of the air duct 30 facing the mounting groove 121, condensate or incompletely atomized atomized matrix can be collected in the air inlet chamber 122.

[0065] When there is a large amount of backflowing condensate or incompletely atomized atomized matrix in the air inlet chamber 122, in order to further prevent it from flowing back to the airflow sensor 40 through the sensing channel 33, as shown in Figure 6, the first guide post 331 is set to protrude from the side of the air passage 30 facing the mounting groove 121 at a height higher than that of the second guide post 321. Even if the amount of backflowing condensate or incompletely atomized atomized matrix is ​​sufficient to exceed the height of the second guide post 321, it will only flow back to the outer surface of the atomizing device through the air guide hole 531 via the second guide post 321, and will not affect the normal use of the airflow sensor 40.

[0066] In actual use, the amount of backflowing condensate or incompletely atomized atomized matrix is ​​very small. The purpose of setting the first guide post 331 and the second guide post 321 is to prevent them from flowing back through the sensing channel 33 or the air intake channel 32.

[0067] In some embodiments, the height of the first guide post 331 and the height of the second guide post 321 are both lower than the height of the air intake chamber 122, so that both the first guide post 331 and the second guide post 321 can remain in communication with the air intake chamber 122.

[0068] In this embodiment, the height of the first guide post 331 and the height of the second guide post 321 are both higher than the height of the air intake chamber 122. To ensure that both the first guide post 331 and the second guide post 321 can maintain communication with the air intake chamber 122, as shown in Figures 2, 4, 9, and 11, a first clearance groove 1211 is provided on the side of the mounting groove 121 facing the first guide post 331 to prevent the end of the first guide post 331 from being away from the air passage component 30. A second clearance groove 1222 is provided on the side of the mounting groove 121 facing the second guide post 321 to prevent the end of the second guide post 321 from being away from the air passage component 30.

[0069] In this embodiment, the liquid storage chamber 10 includes a chamber body 11 and a first sealing member 12. One end of the chamber body 10 has an opening, and the first sealing member 12 is sealed to the opening of the chamber body 11 so that the first sealing member 12 and the chamber body 11 form a liquid storage cavity 101. The mounting groove 121 is formed on the side of the first sealing member 12 facing away from the liquid storage cavity 101, and at least a portion of the groove wall of the mounting groove 121 is arranged around the air inlet end of the atomizing channel 211.

[0070] In one embodiment, the liquid storage chamber 10 further includes a second sealing member 13. The other end of the chamber body 11 also has an opening. The second sealing member 13 is sealed and connected to the opening at the other end of the chamber body 11. The space enclosed by the chamber body 11, the first sealing member 12 and the second sealing member 132 forms the liquid storage cavity 101.

[0071] The atomizing device provided in this embodiment also includes a housing assembly 50 and a mounting bracket 60. The housing assembly 50 has a receiving cavity 501 inside, and the liquid storage tank 20 and the mounting bracket 60 are both disposed inside the receiving cavity 501. The liquid storage tank 20 is mounted on the mounting bracket 60.

[0072] In one embodiment, the housing assembly 50 has a vent 531 that communicates with the receiving cavity 501. The vent 531 is connected to the interior of the receiving cavity 501 and can communicate with the outside atmosphere.

[0073] The air vent 531 connects the housing cavity 501 of the outer casing assembly 50 to the external atmosphere. For user convenience, the outer casing assembly 50 is also equipped with a suction nozzle 521. The suction nozzle 521 has a suction nozzle channel 522, wherein one end of the air intake channel 32 can communicate with the air vent 531, and the other end of the air intake channel 32 can communicate with the atomization channel 211. The atomization channel 211 is located inside the aerosol channel 1021, and since the aerosol channel 1021 can extend to the outside of the outer casing assembly 50 through the suction nozzle channel 522 of the suction nozzle 521, the user can draw in external air through the air vent 531 into the air intake channel 32 by suction through the suction nozzle 521.

[0074] In related technologies, since the air passage 30 has a certain distance between the air guide holes 531 to form a large space, when the user is performing suction, the external atmosphere enters the space through the air guide holes 531 and is prone to generating eddies, which will generate a certain suction resistance and affect the user experience.

[0075] As shown in Figures 2-4, in this embodiment, an air intake column 61 is provided on the mounting bracket 60. As shown in Figures 5 and 13, an air intake hole 611 is formed through the interior of the air intake column 61 along its axial direction, with one end of the air intake hole 611 facing the air guide hole 531. The end of the second guide post 321 away from the mounting groove 121 is inserted into the interior of the air intake column 61, so that the air intake channel 32 is connected to the air intake hole 611.

[0076] In the above embodiments, the air guide hole 531 is guided to communicate with the air intake channel 32 through the air intake column 61, which can shorten the length of the airflow and thus avoid the generation of vortex phenomenon.

[0077] In a specific embodiment, the outer shell assembly 50 includes a main shell 51, an upper cover 52, and a lower cover 53. The main shell 51 is a cylindrical structure with a hollow interior and open ends. The upper cover 52 and the lower cover 53 are respectively connected to the open ends of the main shell 51, so that the main shell 51, the upper cover 52, and the lower cover 53 form a receiving cavity 501. The air vent 531 is provided on the lower cover 53.

[0078] In one embodiment, the atomizing device 100 draws in external air through the air guide hole 531 into the receiving cavity 501. Therefore, a suction nozzle 521 is also provided on the upper cover 52, which allows the user to easily draw in air.

[0079] In some embodiments, to facilitate suction by the user through the suction nozzle 521, as shown in Figure 3, a suction nozzle channel 522 is also provided inside the suction nozzle 521. During the suction process, external air can drive the aerosol through the suction nozzle channel 522 and output it through the suction nozzle 521.

[0080] The atomizing core assembly 20 can heat and atomize the atomizing matrix to produce an aerosol, which can be output through the mouthpiece 521 for user use.

[0081] One end of the liquid storage chamber 10 is the first sealing element 12. A mounting groove 121 is located on the side of the first sealing element 12 facing the mounting bracket 60, while the atomizing channel 211 is located on the side of the first sealing element 12 facing the liquid storage component 102. An aerosol channel 1021 is provided inside the liquid storage component 102. Referring to Figures 5 and 8, the atomizing channel 211 extends towards the liquid storage component 102 and protrudes from the first sealing element 12. After the first sealing element 12 is installed into the opening at the lower end of the liquid storage chamber 10, the atomizing channel 211 is inserted into the aerosol channel 1021.

[0082] Referring to Figure 3, the atomizing core assembly 20 includes an atomizing tube 21, a liquid guide (not shown in the figure), and a heating element (not shown in the figure). The atomizing tube 21 is disposed in the aerosol channel 1021 of the liquid storage component 102. The atomizing tube 21 passes through the second sealing member 13 and is connected to the mouthpiece channel 522. The aforementioned atomizing channel 211 is inserted inside the atomizing tube 21. A connection port 212 is provided on the atomizing tube 21. The liquid guide is installed inside the atomizing tube 21 and extends through the connection port 212 to the outside of the atomizing tube 21 to contact the liquid storage component 102. This allows the atomizing matrix stored in the liquid storage component 102 to be conducted to the heating element. The heating element is wrapped around the portion of the liquid guide located inside the atomizing tube 21. The heating element can heat the atomizing matrix to generate aerosol.

[0083] To prevent foreign objects from entering the product through the nozzle channel 522 and affecting its normal use, a sealing element 523 is installed at the nozzle channel 522 when the product leaves the factory. During the storage and transportation of this atomizing device 100, the sealing element 523 seals the nozzle channel 522.

[0084] As mentioned earlier, one end of the air inlet 611 of the air inlet column 61 faces the air guide 531 and is connected to the air guide 531, while the other end of the air inlet 611 is connected to the air intake channel 32. As shown in Figure 3, when the user sucks through the nozzle 521, an environment with a lower pressure than the external air is formed in the nozzle channel 522, atomizing tube 21, atomizing channel 211, air intake chamber 122, air intake channel 32, and air inlet 611. Then, the external air can flow in the direction of the air guide 531, air inlet 611, air intake channel 32, air intake chamber 122, atomizing channel 211, atomizing tube 21, and nozzle channel 522. In this way, the flowing air creates a negative pressure inside the receiving groove 31 through the sensing channel 42. After the airflow sensor 40 senses the change in air pressure, it can generate a control signal.

[0085] It should be noted that the airflow sensor 40 is electrically connected to the heating element in the atomizing core assembly 20. The heating element can be controlled by a control signal to heat the atomizing matrix conducted by the liquid guiding element, thereby generating aerosol particles. The generated aerosol particles then flow with the airflow through the atomizing tube 21 and the mouthpiece channel 522, and are output through the mouthpiece 521 for user use.

[0086] When the user stops pumping, since there is no airflow, the airflow sensor 40 cannot detect the change in air pressure, and thus controls the heating element to stop working.

[0087] In this application, the air inlet channel 32 on the air duct component 30 is kept in communication with the air inlet hole 611 in the air inlet column 61 of the mounting bracket 60. The airflow entering from the outside can directly enter the air inlet channel through the air inlet hole 611, which can avoid the airflow generating eddy currents in the space between the liquid storage tank 10 and the lower cover 53.

[0088] Meanwhile, an air inlet channel 32 and a sensing channel 33 are respectively provided on the air duct component 30, and only the sensing channel 33 is connected to the receiving groove 31. After the air duct component 30 is installed into the mounting groove 121, the atomizing channel 211, the air inlet channel 32, and the sensing channel 33 are misaligned. In this way, the condensate generated by the aerosol or the incompletely atomized atomized matrix will not flow back to the airflow sensor 40 directly through the sensing channel 33, nor will it flow back to the air guide hole 531 through the air inlet channel 32. This extends the service life of the atomizing device while also ensuring the aesthetic appearance of the outer surface of the atomizing device.

[0089] In this embodiment, to further reduce the backflow of condensate, as shown in Figures 2-5, a liquid suction element 5211 is provided between the suction nozzle 521 and the second sealing element 13, which can absorb the backflowed condensate.

[0090] In this application, the heating element in the atomizing core assembly 20 is heated by electrical energy. The atomizing device 100 provided in this application also includes a battery 70 and a circuit board 80. The battery 70 and the circuit board 80 are disposed in the receiving cavity 501. The output end of the circuit board 80 is electrically connected to the heating element, and the input end is electrically connected to the battery 70, so as to realize the power supply to the heating element through the circuit board 80.

[0091] In this embodiment, the battery 70 and the liquid storage tank 10 are mounted side by side on the mounting bracket 60, as shown in Figure 13. The mounting bracket 60 is also provided with a slot 63, in which the battery 70 is inserted. The circuit board 80 is disposed between the liquid storage tank 10 and the mounting bracket 60. The mounting bracket 60 is located above and adjacent to the lower cover 53. One end of the air inlet 611 faces the air guide hole 531, which can shorten the distance between the air guide hole 531 and the air inlet 611. When the user sucks through the suction nozzle 521, the outside air can quickly enter the air inlet 611 through the air guide hole 531, avoiding the formation of turbulence in the air entering the receiving cavity 501.

[0092] In a specific embodiment, as shown in Figures 3, 8, 9, and 11, the circuit board 80 is disposed on the side of the air passage 30 facing away from the mounting groove 121, and cooperates with the air passage 30 to seal the receiving groove 31. A conductive electrode 81 is disposed on the side of the circuit board 80 facing away from the liquid storage tank 10, as shown in Figure 13. The mounting bracket 60 is provided with a third guide post 62, which has a connecting hole 621. The conductive electrode 81 passes through the connecting hole 621 and is electrically connected to the battery 70.

[0093] As shown in Figure 3, the atomizing device 100 provided in this embodiment also includes a conductive element 82, which is fixed on the lower cover 13. The two ends of the conductive element 82 abut against the conductive electrode 81 and the battery 70, respectively. The conductive element 82 is electrically connected to the conductive electrode 81 and the battery 70, thereby electrically connecting the conductive electrode 81 and the battery 70.

[0094] The first sealing element 12 of the liquid storage chamber 10 is also provided with a first pin mounting hole 124 and a second pin mounting hole 125. The first pin mounting hole 124 is used to install a first pin that is electrically connected to the heating element in the atomizing core assembly 20, and the second pin mounting hole 125 is used to install a second pin that is connected to the conductive electrode 81. After the first pin and the second pin are electrically connected, the conductive electrode 81 can be electrically connected to the heating element, thereby providing electrical energy to the heating element through the battery 70. In this embodiment, two first pin mounting holes 124 are provided on one side of the first sealing element 12, and two second pin mounting holes 125 are provided on the other side of the first sealing element 12, corresponding to the positive and negative terminals of the battery 70, respectively.

[0095] In order to facilitate the connection between the conductive electrode 81 and the second pin, in this embodiment, the conductive electrode 81 passes through the circuit board 80, and the first sealing member 12 is also provided with a third clearance groove 1213 to avoid the conductive electrode 81.

[0096] As shown in Figure 5, a clearance hole 83 is also provided on the circuit board 80 to avoid the end of the second guide post 321 that is away from the mounting groove 121, so that the second guide post 321 can communicate with the air intake hole 611 of the air intake post 61 through the clearance hole 83.

[0097] As shown in Figure 4, the end of the second guide post 321 away from the mounting groove 121 is inserted into the air inlet 611 of the air inlet post 61, and the outer diameter of the third guide post 422 is smaller than the inner diameter of the air inlet post 61, that is, smaller than the diameter of the air inlet 611.

[0098] In summary, the atomizing device provided in this application has an air passage component with an air inlet channel and a sensing channel installed in a mounting groove at one end of the liquid storage tank. This saves space for the air passage structure, reduces the internal structural layout space of the atomizing device, further reduces the overall volume of the atomizing device, is beneficial to users, and improves the user experience.

[0099] By maintaining communication between the air inlet channel on the air duct component and the air inlet hole in the air inlet column of the mounting bracket, external airflow can directly enter the air inlet channel through the air inlet hole, avoiding turbulence in the space between the liquid storage tank and the lower cover. Simultaneously, the air duct component is equipped with both an air inlet channel and a sensing channel, with only the sensing channel connected to the receiving groove. After the air duct component is installed in the mounting groove of the bracket, the atomizing channel, air inlet channel, and sensing channel are staggered. This prevents condensate or incompletely atomized atomized matrix from flowing back to the airflow sensor via the sensing channel, and also prevents backflow to the mounting groove via the air inlet channel. This extends the service life of the atomizing device while maintaining its aesthetic appearance.
