DETAILED DESCRIPTION

[0032] The application will be described in further detail below with reference to the drawings and embodiments. It is particularly pointed out that the following embodiments are only for illustrating the application, but not for limiting the scope of the application. Similarly, the following embodiments are only part of the embodiments of the application, but not all the embodiments of the application. All other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0033] In the present application, the phrase "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0034] Please refer to Figures 1-2 , Figure 1 is a structural schematic diagram of the atomization device 10 provided by the embodiments of the present application, Figure 2 is Figure 1 a sectional structural schematic diagram of the atomization device 10 along V-V in the embodiment.

[0035] The atomizing device 10 provided in this application embodiment can contain atomizing liquid and can atomize the atomizing liquid. For example, the atomization method includes at least one of heating atomization, high-frequency vibration atomization, and catalytic atomization. The composition of the atomizing liquid is different for different atomization methods so that the atomizing liquid can be atomized to form an aerosol.

[0036] In one embodiment, the atomizing device 10 is an electronic cigarette, and the atomizing liquid can be an e-liquid solution containing nicotine or nicotine salts. The nicotine can be obtained from natural tobacco or can be artificially synthesized. The solution may also include propylene glycol, glycerol, and food-grade flavorings or natural flavor extracts.

[0037] In another embodiment, the nebulizing liquid can also be an extract containing other herbal plants with medicinal value. That is, the nebulizing device 10 in this embodiment can also be used as a drug delivery device, such as a nebulizer. Of course, the types of nebulizing device 10 and nebulizing liquid are not limited to these, and will not be described in detail here.

[0038] like Figures 1-2 As shown, the atomizing device 10 may include: a housing assembly 100, a liquid storage assembly 200, a heating assembly 300, and a control assembly 400. The housing assembly 100 is for the user to grip and inhale, and it also houses and mounts the functional components required by the atomizing device 10. The liquid storage assembly 200 is located within the housing assembly 100 and is used to store the atomizing substrate. The liquid storage assembly 200 also has a sensing airway 201 and an atomizing airway 202 connected to the housing assembly 100, and an air inlet duct 203 connecting the external atmosphere to the sensing airway 201 and the atomizing airway 202. The heating assembly 300 may be located within the atomizing airway 202 and can heat the substrate entering the atomizing airway 202 to atomize it into an aerosol. The control component 400 is located inside the housing component 100 and can be electrically connected to the heating component 300. The control component 400 can detect the airflow in the intake air passage 303 to control the heating component 300 to operate. Figure 2 The dashed arrow in the middle shows the airflow path of the sensing airway 201.

[0039] When the user sucks the mouthpiece assembly 100, air can enter the induction air passage 201 and the atomization air passage 202 from the air inlet passage 203 respectively, and can enter the shell assembly 100 through the induction air passage 201 and the atomization air passage 202, and then be guided out of the shell assembly 100. At the same time, the control assembly 400 can detect the air flow formed in the air inlet passage 203, and control the heating assembly 300 to heat the to-be-atomized substrate in the atomization air passage 202, so that the to-be-atomized substrate is atomized to form an aerosol for being taken out by the air entering the atomization air passage 202. Wherein, since the to-be-atomized substrate can be solid or semi-solid before being heated, when the atomization air passage 202 is blocked due to the solidification of the residual aerosol, the induction air passage 201 can still be in communication with the air inlet passage 303 to form an air flow to trigger the control assembly 400, so that the control assembly 400 can control the heating assembly 300 to work, thereby ensuring that the atomization device 10 can be normally started.

[0040] The shell assembly 100 has a containing space 101 for installing functional devices required by the atomization device 10, and can communicate the external atmosphere with the induction air passage 201 and the atomization air passage 202 of the liquid storage assembly 200. Figures 1-2 As shown in the figure, the shell assembly 100 can include a shell 110 and a mouthpiece 120. Wherein, the shell 110 can be connected with the mouthpiece 120, and the shell 110 is surrounded to form the containing space 101, and the shell 110 can also be gripped by the user. The mouthpiece 120 can be connected with the shell 110, and can communicate the external atmosphere with the induction air passage 201 and the atomization air passage 202, and the mouthpiece 120 can also be sucked by the user to perform suction, so that the mouthpiece 120 can guide the air in the induction air passage 201 and the atomization air passage 202 out.

[0041] In order to improve the assembly convenience of the atomization device 10, the shell 110 can be disassembled into an outer frame 111 and a bottom shell 112. As shown in the figure, Figures 1-2 The outer frame 111 can be a hollow cuboid structure, and the opposite sides of the outer frame 111 are both formed with openings. The bottom shell 112 can be covered on the side of the outer frame 111 with the opening, and can be surrounded with the outer frame 111 to form the aforementioned containing space 101. The mouthpiece 120 can be covered on the other opposite side of the outer frame 111 with the opening, and can communicate the containing space 101 with the external atmosphere. Of course, the shell 110 can also not be limited to being disassembled into the outer frame 111 and the bottom shell 112, and the disassembly manner of the shell 110 can be various, which will not be enumerated one by one in the embodiment.

[0042] The bottom shell 112 can be provided with an air inlet hole 102 for communicating the accommodating space 101 with the external atmosphere, and the air inlet channel 203 can communicate the external atmosphere through the accommodating space 101 and the air inlet hole 102. When the user sucks the suction nozzle 120, the external air can enter the accommodating space 101 from the air inlet hole 102, and then enter the air inlet channel 203 through the accommodating space 101, and then be guided out through the induction channel 201, the atomization channel 202 and the suction nozzle 120.

[0043] In some embodiments, the air inlet hole 102 can also not be limited to being provided on the bottom shell 112. For example, the air inlet hole 102 can also be provided on the outer frame 111 to communicate the accommodating space 101 with the external atmosphere. Alternatively, the air inlet hole 102 can be provided on both the outer frame 111 and the bottom shell 112 to increase the air intake of the atomization device 10.

[0044] In some embodiments, the shape of the outer frame 111 can also not be limited to a cuboid, and the specific shape of the outer frame 111 can be selected according to design requirements. For example, the outer frame 111 can also be a hollow cylindrical structure, and the outer frame 111 is formed with openings on opposite sides in the axial direction.

[0045] In some embodiments, the outer frame 111 and the bottom shell 112 can also be an integral structure. That is, the outer shell 110 can also not be designed as a separate part, and the outer shell 110 can be integrally formed by an integral molding process such as injection molding, which is not limited in the present embodiment.

[0046] All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0047] Please refer to Figure 2 Please refer to Figures 3-4 , Figure 3 is Figure 2 a local enlarged view of part A in FIG. 8, Figure 4 is Figure 2 a structural view of the suction nozzle 120 in FIG. 8.

[0048] The suction nozzle 120 can communicate the external atmosphere with the induction channel 201 and the atomization channel 202, and can be used for the user to suck. As Figures 2-3As shown, the suction nozzle 120 can have suction holes 1201 and suction grooves 1202. Among them, the suction holes 1201 can be through the suction nozzle 120 on the opposite sides close to and away from the bottom shell 112 to communicate the induction air channel 201 and the external atmosphere. The suction grooves 1202 can also be through the suction nozzle 120 on the opposite sides close to and away from the bottom shell 112 to communicate the atomization air channel 202 and the external atmosphere. At the same time, the suction holes 1201 and the suction grooves 1202 can be independent of each other, when the user holds the suction nozzle 120 to suck, the air in the induction air channel 201 can be guided out through the suction holes 1201, and the air with aerosol in the atomization air channel 202 can be guided out through the suction grooves 1202, so that the aerosol in the atomization air channel 202 cannot enter the suction holes 1201, to avoid the suction holes 1201 being blocked by the solidified aerosol. In addition, the number of suction grooves 1202 can also be two, and the two suction grooves 1202 can also be independent of each other to respectively communicate with the two atomization air channels 202 of the liquid storage assembly 200.

[0049] In order to form independent suction holes 1201 and suction grooves 1202, the suction nozzle 120 can include a main body part 121 and a separation part 122. As shown, Figures 3-4 The main body part 121 can be connected with the side of the outer frame 111 away from the bottom shell 112, and the main body part 121 can surround the through groove 1203 formed to communicate the external atmosphere and the containing space 101. The separation part 122 is connected with the main body part 121 and located in the through groove 1203 of the main body part 121, and the separation part 122 can separate the through groove 1203 of the main body part 121 into two suction grooves 1202, so that the two suction grooves 1202 are independent of each other. At the same time, the separation part 122 can also be provided with the aforementioned suction holes 1201, and the suction holes 1201 can be through the separation part 122 on the opposite sides close to and away from the bottom shell 112, so that the suction holes 1201 are independent of the two suction grooves 1202.

[0050] In order to realize the communication of the suction holes 1201 and the induction air channel 201, the part of the separation part 122 constituting the hole wall of the suction holes 1201 can be inserted into the induction air channel 201 to communicate the suction holes 1201 and the induction air channel 201, and to reduce the probability of aerosol in the suction grooves 1202 entering the suction holes 1201 and the induction air channel 201. Similarly, in order to realize the communication of the suction grooves 1202 and the atomization air channel 202, the part of the liquid storage assembly 200 having the gas outlet of the atomization air channel 202 can also be inserted into the suction grooves 1202 to communicate the suction grooves 1202 and the atomization air channel 202, and to reduce the probability of aerosol in the suction grooves 1202 entering the suction holes 1201 and the induction air channel 201.

[0051] In some embodiments, the connection between the air inlet hole 1201 and the induction air passage 201, and the connection between the air inlet groove 1202 and the atomization air passage 202 can also have various forms, which are not limited to the plug-in connection shown in the foregoing embodiments. As long as the connection between the air inlet hole 1201 and the induction air passage 201 can be independent of the connection between the air inlet groove 1202 and the atomization air passage 202, the specific structure of the mouthpiece 120 is not limited herein.

[0052] In some embodiments, in addition to the two air inlet grooves 1202 being connected to the two atomization air passages 202 of the liquid storage assembly 200 respectively, the two air inlet grooves 1202 can be combined into one larger air inlet groove 1202 to connect the two atomization air passages 202 of the liquid storage assembly 200 simultaneously. That is, the isolation portion 122 can not separate the through groove 1203 of the main body portion 121 into two air inlet grooves 1202, but the through groove 1203 of the main body portion 121 can be regarded as one larger air inlet groove 1202, and the isolation portion 122 can only be used to form the air inlet hole 1201 to keep the air inlet hole 1201 and the air inlet groove 1202 independent.

[0053] In some embodiments, considering that the mouthpiece 120 is directly connected to the external atmosphere, it is generally difficult for aerosol to remain in the mouthpiece 120 and solidify, and even if aerosol remains in the mouthpiece 120 and solidifies, the mouthpiece 120 is relatively easy to clean, and the induction air passage 201 and the atomization air passage 202 are not blocked. Therefore, the mouthpiece 120 can only include the main body portion 121, and the through groove 1203 formed by the main body portion 121 can simultaneously connect the induction air passage 201 and the atomization air passage 202, so that the air in the induction air passage 201 and the atomization air passage 202 can be guided out through the through groove 1203, thereby simplifying the structure of the mouthpiece 120 and reducing the production cost of the mouthpiece 120.

[0054] It can be understood that the structure of the mouthpiece 120 can have various forms in addition to the forms shown in the foregoing embodiments, and the specific structure of the mouthpiece 120 can be selected according to the design requirements of the atomization device 10. As long as the mouthpiece 120 can connect the external atmosphere to the induction air passage 201 and the atomization air passage 202, the specific structure of the mouthpiece 120 is not limited herein.

[0055] Please refer to Figures 2-3 Please refer to Figures 5-7 , Figure 5 is Figure 2 a partial enlarged view of position B in FIG. 1, Figure 6 is Figure 1 a sectional structure view of the atomization device 10 along VI-VI in FIG. 1, Figure 7 is Figure 6 a partial enlarged view of position C in FIG. 1, Figure 8 is Figure 2 a structure view of the liquid storage assembly 200 in FIG. 1.

[0056] The liquid storage assembly 200 is integrally or removably arranged in the atomization device 10, i.e. in the accommodation space 101, and can store liquid atomization substrate and has an induction air passage 201, an atomization air passage 202 and an air inlet passage 203. As shown in Figure 2 and Figure 3 The liquid storage assembly 200 also has an air outlet end 204 arranged adjacent to the suction nozzle 120, and the air outlet end 204 can be inserted into the through slot 1203 formed by the main body 121. The induction air passage 201 has a first air port 2011 (shown in Figure 3 ) communicating with the air outlet end 204, and a second air port 2012 (shown in Figure 5 ) communicating with the air inlet passage 203, and the air suction hole 1201 can communicate with the induction air passage 201 through the first air port 2011. The atomization air passage 202 has a third air port 2021 (shown in Figure 3 ) communicating with the air outlet end 204, and a fourth air port 2022 (shown in Figure 7 ) communicating with the air inlet passage 203, and the air suction groove 1202 can communicate with the atomization air passage 202 through the third air port 2021. The air inlet passage 203 can be arranged away from the air outlet end 204 and can communicate with the external atmosphere through the accommodation space 101 and the air inlet hole 102, and the air inlet passage 203 can also be installed with a detection component of the control assembly 400, so that the control assembly 400 can detect the airflow in the air inlet passage 203.

[0057] In this embodiment, by arranging the induction air passage 201 to have the first air port 2011 communicating with the air outlet end 204, and the second air port 2012 communicating with the air inlet passage 203, and the atomization air passage 202 to have the third air port 2021 communicating with the air outlet end 204, and the fourth air port 2022 communicating with the air inlet passage 203, the induction air passage 201 and the atomization air passage 202 can be independent, so as to respectively conduct the air of the air inlet passage 203 to the air outlet end 204, and further guided out by the air suction hole 1201 and the air suction groove 1202 of the suction nozzle 120. In this way, when the atomization air passage 202 is blocked, the induction air passage 201 can still communicate with the air inlet passage 203 to form airflow, so as to trigger the detection component of the control assembly 400 installed in the air inlet passage 203, thereby ensuring that the atomization device 10 can be normally started.

[0058] Figure 6 The dashed arrows show the airflow path of the atomization air passage 201. The terms "first", "second", "third" in the present application are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", "third" can explicitly or implicitly include at least one of the features.

[0059] The liquid storage assembly 200 also has a liquid storage cavity 205 for containing a liquid to be atomized, and the induction air passage 201 and the atomizing air passage 202 can also be located in the liquid storage cavity 205. As shown in Figure 2 , Figure 6 and Figure 8 , the liquid storage assembly 200 can include a liquid storage shell 210, a top cover 220, and a bottom cover 230. The opposite sides of the liquid storage shell 210 can be connected with the top cover 220 and the bottom cover 230 respectively, and the liquid storage shell 210 can also cooperatively form the liquid storage cavity 205 with the top cover 220. Meanwhile, the top cover 220 can be arranged adjacent to the mouthpiece 120, and the end where the top cover 220 is located can be the air outlet end 204 of the liquid storage assembly 200.

[0061] In some embodiments, the gas guide tube 240 can also constitute the complete induction air passage 201. For example, one end of the gas guide tube 240 can be arranged through the top cover 220 and can be flush with the side of the top cover 220 away from the bottom cover 230, and the one end of the gas guide tube 240 arranged through the top cover 220 has a first air port 2011, and part of the hole wall of the air inlet hole 1201 constituted by the isolation portion 122 can be inserted into the gas guide tube 240 from the first air port 2011 to realize the communication between the air inlet hole 1201 and the gas guide tube 240. Meanwhile, the other opposite end of the gas guide tube 240 can be arranged through the liquid storage shell 210 in the direction away from the top cover 220, and the other opposite end of the gas guide tube 240 can have a second air port 2012 to communicate with the air inlet passage 203 on the bottom cover 230 after passing through the liquid storage shell 210.

[0062] In some embodiments, the atomizing tube 250 can also constitute the complete atomizing air passage 202. For example, one end of the atomizing tube 250 can be inserted into the top cover 220 and can be flush with the side of the top cover 220 away from the bottom cover 230, and the one end of the atomizing tube 250 inserted into the top cover 220 can have a third air port 2021 located in the inhalation groove 1202, and the inhalation groove 1202 can be connected to the atomizing tube 250 through the third air port 2021. Meanwhile, the other end of the atomizing tube 250 can be inserted into the liquid storage shell 210 in a direction away from the top cover 220, and the other end of the atomizing tube 250 can have a fourth air port 2022 to be connected to the air inlet passage 203 on the bottom cover 230 after passing through the liquid storage shell 210.

[0063] Please refer to Figure 3 Please refer to Figure 9 , Figure 9 is Figure 8 the exploded structural diagram of the top cover 220.

[0064] The top cover 220 can also constitute at least part of the induction air passage 201 together with the air guide tube 240. As shown in Figure 3 , the top cover 220 is connected to the end of the air guide tube 240 away from the bottom cover 230, and has a connecting hole 2201 connected to the air guide tube 240. Meanwhile, the connecting hole 2201 has a first air port 2011 formed on the side of the top cover 220 away from the bottom cover 230, and the inhalation hole 1201 can be connected to the connecting hole 2201 through the first air port 2011. In addition, the inner tube wall of the air guide tube 240 and the hole wall of the connecting hole 2201 can also constitute at least part of the induction air passage 201. In this embodiment, the inner tube wall of the air guide tube 240 and the hole wall of the connecting hole 2201 can constitute part of the induction air passage 201.

[0065] In order to realize the connection of the air guide tube 240 and the connecting hole 2201, the end of the air guide tube 240 away from the bottom cover 230 can be inserted into the connecting hole 2201, and the air guide tube 240 can be interference-fitted with the hole wall of the connecting hole 2201 to improve the sealing of the connection of the air guide tube 240 and the connecting hole 2201.

In some embodiments, the air guide tube 240 can also not be limited to interference-fitting with the hole wall of the connecting hole 2201, but only needs to be inserted into the connecting hole 2201 to be connected to the connecting hole 2201, and the inhalation hole 1201 and the connecting hole 2201 are the same, and this embodiment does not limit this.

[0066] One end of the air guide tube 240 inserted into the connecting hole 2201 can also be connected to a portion of the isolation part 122 inserted into the connecting hole 2201. Furthermore, the air guide tube 240 can be coaxially arranged with the connecting hole 2201, allowing gas to directly enter the intake hole 1201 from the air guide tube 240 without needing to be conducted through the connecting hole 2201. Of course, in some embodiments, the end of the air guide tube 240 inserted into the connecting hole 2201 can also be spaced apart from a portion of the isolation part 122 inserted into the connecting hole 2201, requiring the gas in the air guide tube 240 to be conducted through the connecting hole 2201 to the intake hole 1201.

[0067] In some embodiments, the communication method between the connecting hole 2201 and the air guide tube 240 and the suction port 1201 is not limited to the plug-in communication shown in the above embodiments, and there can be multiple other communication methods between the connecting hole 2201 and the air guide tube 240 and the suction port 1201. For example, one end of the air guide tube 240 can abut against the side of the top cover 220 facing the bottom cover 230, and the air guide tube 240 can be coaxially arranged with the connecting hole 2201. The diameter of the connecting hole 2201 can also be less than or equal to the outer diameter of the air guide tube 240, so that the air guide tube 240 can be connected to the connecting hole 2201 without being inserted into the connecting hole 2201. Similarly, the connecting hole 2201 and the suction port 1201 can also be connected in the same or similar way, which will not be described in detail in this embodiment.

[0068] The top cap 220, together with the atomizing tube 250, can form at least a partial atomizing airway 202. For example... Figure 3 As shown, the top cover 220 can be connected to the end of the atomizing tube 250 away from the bottom cover 230, and has an air outlet 2202 communicating with the atomizing tube 250. Simultaneously, the air outlet 2202 has a third air port 2021 formed on the side of the top cover 220 opposite to the bottom cover 230, and the intake groove 1202 can communicate with the air outlet 2202 through the third air port 2021. Furthermore, the inner wall of the atomizing tube 250 and the wall of the air outlet 2202 can constitute at least a partial atomizing airway 202. In this embodiment, the inner wall of the atomizing tube 250 and the wall of the air outlet 2202 can constitute a partial atomizing airway 202.

At the same time, in order to realize the communication between the air inlet groove 1202 and the air outlet hole 2202, the third air port 2021 formed on the top cover 220 away from the bottom cover 230 can also be located in the air inlet groove 1202, so that the air inlet groove 1202 can be communicated with the air outlet hole 2202 through the third air port 2021.

[0070] In some embodiments, the communication mode of the air outlet hole 2202 and the atomizing pipe 250 can not be limited to the plug-in communication shown in the above-mentioned embodiments, and the communication mode of the air outlet hole 2202 and the atomizing pipe 250 can also have various modes. For example, one end of the atomizing pipe 250 can also abut against the side of the top cover 220 facing the bottom cover 230, and the atomizing pipe 250 can be coaxially arranged with the air outlet hole 2202, and the diameter of the air outlet hole 2202 can be less than or equal to the outer diameter of the atomizing pipe 250, so that the atomizing pipe 250 can be communicated with the air outlet hole 2202 without being inserted into the air outlet hole 2202. Of course, the communication mode of the air inlet groove 1202 and the air outlet hole 2202 can not be limited to the above-mentioned embodiments, and the embodiments will not be listed one by one here.

[0071] The top cover 220 can include a first connecting portion 221, a limiting portion 222 and a liquid suction portion 223. As shown in Figure 3 and Figure 9 , the first connecting portion 221 can be connected with the side of the liquid storage shell 210 away from the bottom cover 230, and can seal the opening of the liquid storage shell 210 away from the bottom cover 230, so as to form the liquid storage cavity 205 together with the liquid storage shell 210. The limiting portion 222 is located on the side of the first connecting portion 221 away from the bottom cover 230, and the liquid suction portion 223 is located between the first connecting portion 221 and the limiting portion 222, and abuts against the first connecting portion 221 and the limiting portion 222, respectively. The connecting hole 2201 can penetrate through the first connecting portion 221 and the limiting portion 222, and the first air port 2011 can be formed on the side of the limiting portion 222 away from the first connecting portion 221.

At the same time, the limiting portion 222 also has an avoiding groove 2221 Figure 8 (shown) which can avoid the other areas of the isolation portion 122 when the isolation portion 122 is inserted into the connecting hole 2201 and forms part of the hole wall of the air inlet hole 1201, so as to avoid the interference between the limiting portion 222 and the suction nozzle 120.

At the same time, the atomizing pipe 250 can also abut against the liquid absorbing portion 223, and the liquid absorbing portion 223 can also shield the gap between the atomizing pipe 250 and the hole wall of the air outlet hole 2202. For example, the hole diameter of the air outlet hole 2202 at the liquid absorbing portion 223 can be smaller than the hole diameter of the air outlet hole 2202 at the first connecting portion 221, so that the liquid absorbing portion 223 can abut against the atomizing pipe 250 to shield the gap between the atomizing pipe 250 and the hole wall of the air outlet hole 2202. In this embodiment, the material of the first connecting portion 221 can be an elastic sealing material such as silica gel, rubber or soft plastic, and the liquid absorbing portion 223 can be liquid absorbing cotton and can be used to absorb the condensed liquid in the atomizing airway 202.

When the touch control 440 is slid to the first gear, the heating assembly 300 in one of the atomization air ducts 202 can start to work. When the touch control 440 is slid to the second gear, the heating assembly 300 in the other atomization air duct 202 can start to work. When the touch control 440 is slid to the third gear, the heating assemblies 300 in the two atomization air ducts 202 can all start to work. In this way, when the sensing element 410 fails or the sensing air duct 201 is blocked, the heating assembly 300 can be controlled to work by using the touch control 440, so as to ensure that the atomization device 10 can be started normally.

[0091] In some embodiments, the atomization device 10 provided by the embodiments can also include a housing, an atomizer, and an energy supplier. The housing can include the housing assembly 110 described above, the atomizer can include the liquid storage assembly 200, the heating assembly 300, the sensing element 410, and the circuit board 420 described above, and the energy supplier can include the battery 430 and the touch control 440 described above.

[0092] The liquid storage assembly 200 provided by the embodiments has the sensing air channel 201 with the first air port 2011 communicating with the air outlet end 204 of the liquid storage assembly 200 and the second air port 2012 communicating with the air inlet channel 203, and the atomization air channel 202 with the third air port 2021 communicating with the air outlet end 204 and the fourth air port 2022 communicating with the air inlet channel 203, so that the sensing air channel 201 and the atomization air channel 202 can be independent to respectively conduct the air in the air inlet channel 203 to the air outlet end 204. In this way, when the atomization air channel 202 is blocked, the sensing air channel 201 can also communicate with the air inlet channel 203 to form an air flow to trigger the sensing element 410 located on the air flow path of the air inlet channel 203 to output an electrical signal, thereby ensuring that the atomization device 10 with the liquid storage assembly 200 can be normally started.

[0093] The above is only the implementation of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent flow transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
