DETAILED DESCRIPTION

[0027] The present application will be further described below in conjunction with the drawings and embodiments. It is particularly pointed out that the following embodiments are only for illustrating the present application, but not for limiting the scope of the present application. Similarly, the following embodiments are only part of the embodiments of the present application, but not all the embodiments of the present application, and all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] In the present application, the phrase "embodiment" means that the specific features, structures or characteristics described in conjunction with the embodiment can be contained in at least one embodiment of the present application. The appearance of this phrase at 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.

[0029] Please refer to Figures 1 to 5 , Figure 1 is a structural schematic diagram of the atomizing device 10 provided by the embodiments of the present application, Figure 2 is Figure 1 a cross-sectional structural schematic diagram of the atomizing assembly 100 along V-V in the atomizing device 10, Figure 3 is Figure 1 a cross-sectional structural schematic diagram of the atomizing assembly 100 along VI-VI in the atomizing device 10, Figure 4 is Figure 2 a partial enlarged schematic diagram of A in the atomizing device 10, Figure 5 is Figure 3 a partial enlarged schematic diagram of B in the atomizing device 10.

[0030] The atomization device 10 provided by the embodiments of the present application can contain atomized liquid and can atomize the atomized liquid. For example, the atomization method includes at least one of heating atomization, high-frequency vibration atomization and catalytic atomization. Corresponding to different atomization methods, the components of the atomized liquid are different, so that the atomized liquid can be atomized to form aerosol.

[0031] In one embodiment, the atomization device 10 is an electronic cigarette, and the atomized liquid can be a tobacco solution containing nicotine or nicotine salt. The nicotine can be extracted from natural tobacco or artificially synthesized. The solution can also include propylene glycol, glycerol and food-grade flavoring essence, or natural flavor extract.

[0032] In another embodiment, the atomized liquid can also be an extract of other herbal plants with use value (such as medical use). That is, the atomization device 10 of the embodiment can also be used as a drug delivery device, such as an atomization drug delivery device. Of course, the types of the atomization device 10 and the atomized liquid are not limited to this, and the embodiments will not be described one by one here.

[0033] As shown in Figures 1 to 2 The atomization device 10 can include an atomization assembly 100 and a sealing assembly 200. The atomization assembly 100 has an air suction end 101, an air inlet end 102 arranged away from the air suction end 101, a gas guide hole 103 in communication with the air suction end 101, and an air inlet hole 104 in communication with the gas guide hole 103. The air inlet hole 104 is located at the air inlet end 102 and is in communication with the external atmosphere. The atomized liquid contained in the atomization assembly 100 can enter the gas guide hole 103 and be heated by the atomization assembly 100 in the gas guide hole 103 to form aerosol. The user can perform suction by holding the air suction end 101, so that the external air can enter the gas guide hole 103 from the air inlet hole 104 and carry the aerosol in the gas guide hole 103 out of the air suction end 101. The sealing assembly 200 can be used to seal the gas guide hole 103 and the air inlet hole 104, so that the atomized liquid stored in the atomization assembly 100 is not easy to leak to various places of the atomization assembly 100 through the gas guide hole 103 and the air inlet hole 104, thereby reducing the risk of liquid leakage of the atomization assembly 100 during transportation.

[0034] The atomization assembly 100 can include a top shell 110, a bottom cover 120 and a connecting bracket 130. As Figures 2 to 3As shown, the top shell 110 is connected with the bottom cover 120, and together with the bottom cover 120, forms the accommodating cavity 105. The end of the top shell 110 away from the bottom cover 120 is the air suction end 101 of the atomization assembly 100, and the end of the bottom cover 120 is the air inlet end 102 of the atomization assembly 100. The connecting bracket 130 is arranged in the accommodating cavity 105, and is arranged opposite and spaced apart from the bottom cover 120. The connecting bracket 130 can divide the accommodating cavity 105 into a first cavity 1051 away from the bottom cover 120 and a second cavity 1052 close to the bottom cover 120. In this embodiment, the first cavity 1051 can be used to accommodate atomization liquid of the atomization assembly 100, and the second cavity 1052 can be configured to provide mounting space for other structural members, such as conductive terminals, sealing bodies, liquid suction members, etc.

[0035] The terms "first", "second", "third" in the present application are only for the purpose of description, 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.

[0036] The top shell 110 and the connecting bracket 130 can jointly form the air guide hole 103, and the bottom cover 120 can have the air inlet hole 104 communicating with the second cavity 1052. Figures 2 to 3 As shown, the top shell 110 has the first conduit 111 arranged in the first cavity 1051, and the first conduit 111 surrounds part of the air guide hole 103 communicating with the air suction end 101. The connecting bracket 130 has the second conduit 131 coaxially connected with the first conduit 111, and the second conduit 131 also surrounds part of the air guide hole 103 communicating with the second cavity 1052. The bottom cover 120 has the air inlet hole 104, and the air inlet hole 104 can penetrate the bottom cover 120 towards the side of the connecting bracket 130 and the side of the bottom cover 120 away from the connecting bracket 130, and can form an air inlet 1041 on the side of the bottom cover 120 away from the connecting bracket 130, that is, on the air inlet end 102, to communicate with the outside atmosphere and the second cavity 1052.

[0037] The first conduit 111 and the second conduit 131 can jointly form the air guide hole 103. As shown, Figures 2 to 3As shown, the air guide hole 103 can include an air outlet section 1031 formed by the first conduit 111, and an atomization section 1032 formed by the second conduit 131. One end of the first conduit 111 can be connected with the air inlet end 101, and the air outlet section 1031 can be formed with an air outlet 1033 on the air inlet end 101 to communicate with the air inlet end 101. One end of the second conduit 131 can be coaxially connected with the other opposite end of the first conduit 111, and the other opposite end can be located in the second cavity 1052, so that the atomization section 1032 can communicate the air outlet section 1031 and the second cavity 1052, and further communicate the air inlet hole 104 through the second cavity 1052.

[0038] The atomization section 1032 can also communicate with the first cavity 1051, and the atomization liquid stored in the first cavity 1051 can enter the atomization section 1032 to be heated by the atomization assembly 100 to form an aerosol in the atomization section 1032. As shown, Figure 3 As shown, the atomization section 1032 can be provided with a notch 1034 on the hole wall to communicate the first cavity 1051, and the atomization liquid stored in the first cavity 1051 can enter the atomization section 1032 through the notch 1034 and be heated by the atomization assembly 100 to form an aerosol in the atomization section 1032. In this embodiment, the hole diameter of the atomization section 1032 can be greater than the hole diameter of the air outlet section 1031, and the atomization section 1032 can be provided with a heating component of the atomization assembly 100 to heat the atomization liquid flowing into the atomization section 1032, so as to atomize the atomization liquid to form an aerosol.

[0039] In some embodiments, the air inlet hole 104 can be arranged non-coaxially with the atomization section 1032, and the axial distance between the air inlet hole 104 and the atomization section 1032 can be greater than the sum of the radii of the air inlet hole 104 and the atomization section 1032, so that the air inlet hole 104 can be located outside the projection profile range of the atomization section 1032 on the bottom cover 120, to reduce the probability of the condensed liquid directly falling from the atomization section 1032 into the air inlet hole 104. Meanwhile, the number of air inlet holes 104 can also be two, and the two air inlet holes 104 can be adjacent to each other on the bottom cover 120 to increase the air intake of the atomization assembly 100 by using the two air inlet holes 104. In some embodiments, the number of air inlet holes 104 can also not be limited to one or two, and the specific number of air inlet holes 104 can be selected according to design requirements, which is not limited in this embodiment.

[0040] In some embodiments, the bottom cover 120 also has a boss 121 protruding towards the connecting bracket 130 and located in the second cavity 1052. As shown, Figures 2 to 3As shown, the air inlet hole 104 can be formed on the boss 121 and extend through the boss 121 towards one side of the connecting bracket 130 and one side of the bottom cover 120 away from the boss 121, and the air inlet hole 104 can form an air inlet 1041 on the side of the bottom cover 120 away from the boss 121 to communicate the second cavity 1052 with the external atmosphere. In the embodiment, the boss 121 is arranged such that liquid leakage of the atomization assembly 100 can only occur when the liquid level is higher than the boss 121, further improving the liquid leakage prevention property of the atomization assembly 100.

[0041] In some embodiments, the number of bosses 121 can also be two, and the two bosses 121 can be arranged at intervals to form the two air inlet holes 104 respectively. The bottom cover 120 further has a reinforcing portion 122 located between the two bosses 121 and connected to the two bosses 121 respectively (as shown), and the reinforcing portion 122 and the two bosses 121 can be an integral structure to improve the structural strength of the two bosses 121. In some embodiments, the number of bosses 121 can also not be limited to two, and the number of bosses 121 can vary with the number of air inlet holes 104, and the plurality of bosses 121 can also not be limited to being connected by the reinforcing portion 122, which is not limited in the present embodiment. In the description of the present application, "plurality" means at least two, for example, two, three, etc., unless otherwise explicitly specified. Figure 4

[0042] Through the above arrangement, when the user sucks at the suction end 101, external air can enter the air inlet hole 104 from the air inlet 1041, and then pass through the second cavity 1052, the atomization section 1032 and the air outlet section 1031 to be discharged from the air outlet 1033 to form an airflow to carry the aerosol in the atomization section 1032. It can be understood that the specific formation of the air guide hole 103 and the air inlet hole 104 in the foregoing embodiments is only exemplary, and the specific formation of the air guide hole 103 and the air inlet hole 104 can also have many other forms, which are not limited to the schemes shown in the foregoing embodiments, as long as the atomization assembly 100 has the air guide hole 103 and the air inlet hole 104 connected, and the air guide hole 103 communicates with the suction end 101 and the air inlet hole 104 communicates with the external atmosphere, which is not enumerated one by one in the present embodiment.

[0043] In order to atomize the liquid to form an aerosol, the atomization assembly 100 can further include a liquid guide 140, an electrically conductive member 150 and a heating member 160. As shown, Figures 4 to 5 ​As shown, the liquid guide 140 can be arranged on the hole wall of the atomization section 1032, and can cover the gaps 1034 on the hole wall of the atomization section 1032, and the liquid guide 140 can guide the atomization liquid in the first cavity 1051 from the gaps 1034 to the atomization section 1032. The conductive member 150 can be arranged on the side of the bottom cover 120 away from the connecting support 130, and can be used for electrical connection with an external power supply. Meanwhile, part of the conductive member 150 can also be arranged through the bottom cover 120 and located in the second cavity 1052. The heating member 160 can be arranged on the liquid guide 140, and part of the heating member 160 can also be in electrical contact with part of the conductive member 150 located in the second cavity 1052. In addition, the heating member 160 can generate heat after being powered on to heat the atomization liquid on the liquid guide 140, so as to atomize the atomization liquid to form aerosol.

[0044] Specifically, the liquid guide 140 can be liquid guide cotton, and the liquid guide 140 can be arranged in a ring shape and attached to the hole wall of the atomization section 1032 to cover the plurality of gaps 1034 on the hole wall of the atomization section 1032. As shown, Figures 4 to 5 As shown, the atomization liquid in the first cavity 1051 can be in contact with the liquid guide 140 through the gaps 1034, and can be absorbed and contained by the liquid guide 140 to be conducted to the atomization section 1032 through the liquid guide 140, so as to be atomized to form aerosol under the heating of the heating member 160.

[0045] In one embodiment, the liquid guide 140 is a porous ceramic, and the inside of the porous ceramic is configured as a non-uniform porous structure to provide capillary force for transferring liquid flow.

[0046] In one embodiment, the liquid guide 140 is a dense device with a micropore array, such as a dense silicon wafer, glass, structural ceramic, etc., which uses the micropore array to leak liquid.

[0047] The conductive member 150 can be an electrode nail, and the conductive member 150 can include a conductive cap 151 and a conductive rod 152. As shown, Figure 5 As shown, the conductive cap 151 can be arranged on the side of the bottom cover 120 away from the connecting support 130, and the conductive cap 151 can be in electrical contact with the conductive structure of the power supply. One end of the conductive rod 152 can be connected with the conductive cap 151, and the other opposite end can be arranged through the bottom cover 120 and located in the second cavity 1052 to be in electrical contact with the heating member 160, so as to realize the electrical connection between the heating member 160 and the power supply. In addition, the number of the conductive member 150 can be two, and the conductive caps 151 of the two conductive members 150 can be connected with the positive and negative electrodes of the power supply respectively, and the conductive rods 152 of the two conductive members 150 can be in electrical contact with the two ends of the heating member 160 respectively.

[0048] The heating element 160 can be similar to a heating wire, and the heating element 160 can include a heating portion 161 and two contact portions 162 connected with the heating portion 161. The heating portion 161 can be embedded in the liquid guide 140, and the heating portion 161 can be a ring-shaped mesh structure to match the shape of the liquid guide 140, so as to uniformly heat the atomized liquid on the liquid guide 140. The two contact portions 162 can be connected with the heating portion 161, and the two contact portions 162 can also extend into the second cavity 1052 to respectively electrically contact the conductive rods 152 of the two conductive elements 150, so as to realize the electrical connection between the heating element 160 and the conductive element 150.

[0049] In some embodiments, the liquid guide 140 can also be other liquid guide elements with liquid guiding capability, and the liquid guide 140 can also not be limited to be arranged in a ring shape, as long as the liquid guide 140 can cover the gap 1034 and can conduct the atomized liquid in the first cavity 1051 to the atomization section 1032. The embodiments are not limited in this regard. Similarly, the conductive element 150 can also not be limited to be an electrode nail, and the conductive element 150 can also be other conductive structures that can realize the electrical connection between the heating element 160 and the power supply. The embodiments are not limited in this regard. In addition, the specific shape of the heating element 160 can also be adaptively adjusted according to design requirements, and is not limited to the schemes shown in the above embodiments. The embodiments are not limited in this regard.

[0050] In order to reduce the risk of liquid leakage of the atomization assembly 100, the atomization assembly 100 can further include a sealing element 170 arranged in the second cavity 1052. As shown in Figures 4 to 5 The sealing element 170 can be arranged between the bottom cover 120 and the connecting bracket 130, and can separate the bottom cover 120 and the connecting bracket 130 to seal the connecting bracket 130. For example, the sealing element 170 can be sealing silica gel, and the peripheral side of the sealing element 170 can be in interference fit with the top shell 110. When the atomized liquid leaks from the gap between the top shell 110 and the connecting bracket 130, the sealing element 170 can play a sealing role to avoid the atomized liquid from further leaking along the top shell 110 to the bottom cover 120. Of course, in addition to the sealing silica gel, the sealing element 170 can also be other sealing structures with sealing capability, and the embodiments are not limited in this regard.

[0051] Since the sealing element 170 separates the bottom cover 120 and the connecting bracket 130, that is, separates the second cavity 1052 into two independent spaces, the air inlet hole 104 cannot communicate with the atomization section 1032 through the second cavity 1052. Based on this, the sealing element 170 can also be provided with a through groove 171 that communicates the bottom cover 120 and the connecting bracket 130, so as to use the through groove 171 to pass through the two spaces separated by the sealing element 170 in the second cavity 1052, thereby realizing the communication between the air inlet hole 104 and the atomization section 1032.

[0052] In some embodiments, the through groove 171 may be located outside the projected contour range of the atomizing section 1032 and the air inlet 104 on the seal 170. This not only prevents condensate from falling directly from the atomizing section 1032 into the through groove 171, but also prevents condensate from falling directly from the through groove 171 into the air inlet 104. Furthermore, there may be two through grooves 171, and the two through grooves 171 may be spaced apart on the seal 170 to increase the air intake of the atomizing section 1032. Of course, the number of through grooves 171 can also be selected according to design requirements, and this embodiment does not limit this.

[0053] To reduce the risk of leakage from the atomizing assembly 100, the atomizing assembly 100 may further include a liquid suction element 180 disposed within the second cavity 1052. For example... Figures 4 to 5 As shown, the liquid-absorbing element 180 can be disposed on the side of the bottom cover 120 facing the seal 170, and the orthogonal projection of the liquid-absorbing element 180 on the seal 170 can also cover the through groove 171, that is, at least a portion of the liquid-absorbing element 180 can be disposed opposite to the through groove 171. Meanwhile, the liquid-absorbing element 180 can be absorbent cotton, and it can absorb and contain the atomized liquid and / or condensate leaking from the through groove 171, thereby reducing the probability of the atomized liquid and / or condensate leaking onto the bottom cover 120. Of course, the liquid-absorbing element 180 can also be a liquid-absorbing element with liquid-absorbing capacity; this embodiment does not limit this.

[0054] All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

Figure 7 yes Figure 1 A schematic diagram of the cross-sectional structure of the atomizing device 10 along line VI-VI.

[0056] The blocking assembly 200 can block the air guide hole 103 and the air inlet hole 104 to reduce the risk of liquid leakage of the atomization assembly 100 during transportation. As shown in Figures 6 to 7 , the blocking assembly 200 can include a first blocking member 210 and a second blocking member 220. The first blocking member 210 can be detachably inserted into the air guide hole 103 and can block the air guide hole 103. The second blocking member 220 can be detachably inserted into the air inlet hole 104 and can block the air inlet hole 104. In this way, the first blocking member 210 and the second blocking member 220 can be used to block the air guide hole 103 and the air inlet hole 104, respectively, so that the atomization liquid stored in the first cavity 1051 is less likely to leak to various parts of the atomization assembly 100 through the air guide hole 103 and the air inlet hole 104, thereby reducing the risk of liquid leakage of the atomization assembly 100 during transportation.

[0057] In addition, by blocking the air guide hole 103 and the air inlet hole 104 with the first blocking member 210 and the second blocking member 220, respectively, the air pressure balance inside the atomization assembly 100 can be maintained, so that the atomization liquid is less likely to leak due to changes in air pressure, thereby further reducing the risk of liquid leakage of the atomization assembly 100 during transportation.

[0058] The first blocking member 210 can be detachably inserted into the air guide hole 103 and can block the air guide hole 103. As shown in Figures 6 to 8 , the first blocking member 210 can be inserted into the air guide hole 103 from the air outlet 1033, and the first blocking member 210 can include an extension portion 211 located in the air outlet section 1031 and an exhaust portion 212 connected to the extension portion 211 and located in the atomization section 1032. The extension portion 211 can be detachably inserted into the air outlet section 1031 from the air outlet 1033, and the shape of the extension portion 211 can match the shape of the air outlet section 1031 and can block the air outlet section 1031. The exhaust portion 212 can be connected to one end of the extension portion 211 inserted into the air outlet section 1031, that is, the end of the extension portion 211 away from the air inlet end 101, and can be inserted into the atomization section 1032 along with the extension portion 211, and the liquid guide member 140 can also be arranged around the exhaust portion 212. In this embodiment, the first blocking member 210 can be made of elastic materials such as silica gel, rubber, and soft plastic.

[0059] By the above arrangement, the first blocking member 210 can block the gas outlet section 1031 by the extending portion 211 to avoid the atomized liquid from leaking along the gas outlet section 1031. Meanwhile, the first blocking member 210 can also occupy part of the space of the atomizing section 1032 by the exhaust portion 212, so that the amount of gas in the atomizing section 1032 is reduced to reduce the amount of change of the gas volume (the change of the gas pressure is reduced) in the atomizing section 1032 under high and low temperature conditions, thereby reducing the probability of the atomized liquid from leaking into the atomizing section 1032 due to the change of the gas pressure.

[0060] In order to improve the convenience of inserting the first blocking member 210, the cross-sectional area of the extending portion 211 in the first direction Z can be reduced or equal, and the shape of the gas outlet section 1031 can be matched with the shape of the extending portion 211 (for example, the hole diameter of the gas outlet section 1031 is reduced or remains unchanged in the first direction Z), and the minimum cross-sectional area of the extending portion 211 can be greater than the maximum cross-sectional area of the exhaust portion 212 in the first direction Z. In this way, when the extending portion 211 is inserted into the gas outlet section 1031, both the extending portion 211 and the exhaust portion 212 can avoid interference with the hole wall of the gas outlet section 1031, thereby improving the convenience of inserting the first blocking member 210.

[0061] Since the extending portion 211 does not interfere with the hole wall of the gas outlet section 1031 (interference fit), there can be a gap (tolerance) between the extending portion 211 and the hole wall of the gas outlet section 1031. At this time, in order to be able to block the gas outlet section 1031, the first blocking member 210 can further include an annular portion 213. As shown in Figures 8 to 9 The annular portion 213 can be arranged around the periphery of the extending portion 211, and the annular portion 213 can be located between the periphery of the extending portion 211 and the hole wall of the gas outlet section 1031, and can be in abutment (interference fit) with the extending portion 211 and the hole wall of the gas outlet section 1031 respectively, to fill the gap between the extending portion 211 and the gas outlet section 1031, thereby blocking the gas outlet section 1031.

[0062] The number of annular portions 213 can be multiple, and the multiple annular portions 213 can be distributed at different positions on the extending portion 211 at intervals in the first direction Z. For example, the number of annular portions 213 can be three, and one annular portion 213 can be located at the end of the extending portion 211 close to the exhaust portion 212, and the other two annular portions 213 can be located at the end of the extending portion 211 close to the gas outlet 10033. Of course, the number of annular portions 213 can also be two, four, five or more, and the specific number of annular portions 213 can be selected according to design requirements, which is not limited in the present embodiment.

[0063] With the above arrangement, compared with the scheme that the whole extension part 211 is in interference fit with the hole wall of the air outlet section 1031 to block, the contact area of the annular part 213 with the hole wall of the air outlet section 1031 is smaller, which is conducive to reducing the friction generated between the extension part 211 and the hole wall of the air outlet section 1031 when being inserted, thereby improving the convenience of inserting the first blocking piece 210. Of course, in some embodiments, the design of the annular part 213 can also be omitted, and the extension part 211 can be directly in interference fit with the hole wall of the air outlet section 1031.

[0064] In order to further improve the sealing performance of the first blocking piece 210, the first blocking piece 210 can further include a first covering part 214. As shown in Figures 6 to 8 , the first covering part 214 can be connected to the end of the extension part 211 away from the exhaust part 212, and the first covering part 214 can be arranged on the air suction end 101 and can cover the air outlet 1033 formed by the air outlet section 1031 on the air suction end 101 to seal the air outlet 1033. At the same time, the shape of the first covering part 214 can match the shape of the air suction end 101 to ensure that the first covering part 214 can be closely attached to the air suction end 101, thereby improving the sealing effect of the first covering part 214. In addition, when the first blocking piece 210 needs to be disassembled, the user can pull out the extension part 211 and the exhaust part 212 by grabbing the first covering part 214 to realize the separable insertion of the first blocking piece 210.

[0065] In some embodiments, the design of the first covering part 214 can also be omitted, and the first blocking piece 210 can only include the extension part 211 and the exhaust part 212. At this time, the end of the extension part 211 away from the exhaust part 212 can protrude from the air suction end 101 to facilitate the user to grab the extension part 211, thereby pulling out the extension part 211 and the exhaust part 212.

[0066] The second blocking piece 220 can be inserted into the air inlet hole 104 in a separable manner and can block the air inlet hole 104. As shown in Figure 6 , Figure 7 and Figure 10 , the second blocking piece 220 can be inserted into the air inlet hole 104 from the air inlet 1041, and the second blocking piece 220 can include a second covering part 221 and a protruding part 222. The second covering part 221 can be arranged on the air inlet end 102 and can cover the air inlet 1041 formed by the air inlet hole 104 on the air inlet end 102 to seal the air inlet 1041. The protruding part 222 can be connected to the second covering part 221 and can be arranged in the air inlet hole 104, and the protruding part 222 can also block the air inlet hole 104. In this embodiment, the second blocking piece 220 can be made of elastic materials such as silica gel, rubber and soft plastic.

[0067] Through the above arrangement, the second blocking piece 220 can seal the air inlet 1041 by using the second covering part 221 to reduce the probability of leakage of atomized liquid and / or condensed liquid from the air inlet 1041. Meanwhile, the second blocking piece 220 can also block the air inlet hole 104 by using the protruding part 222 to avoid the atomized liquid from leaking along the air inlet hole 104.

[0068] The shape of the second covering part 221 can match the shape of the air inlet end 102 to ensure that the second covering part 221 can tightly fit the air inlet end 102, thereby improving the sealing effect of the second covering part 221. Meanwhile, when the second blocking piece 220 needs to be disassembled, the user can pull out the protruding part 222 by grabbing the second covering part 221 to achieve the separable insertion of the second blocking piece 220. In some embodiments, the design of the second covering part 221 can also be omitted, and the second blocking piece 220 can only include the protruding part 222. At this time, the end of the protruding part 222 away from the connecting bracket 130 can be protruding from the air inlet end 102 to facilitate the user to grab the protruding part 222 and pull it out.

[0069] The protruding part 222 can be in interference fit with the hole wall of the air inlet hole 104 to achieve the blocking of the air inlet hole 104, and since the protruding part 222 can be arranged in the air inlet hole 104, the protruding part 222 can not only completely occupy the air inlet hole 104, but also can be protruding in the second cavity 1052 to further reduce the probability of atomized liquid and / or condensed liquid leaking into the air inlet hole 104. Meanwhile, when the number of air inlet holes 104 is two, the number of protruding parts 222 can also be two, and the two protruding parts 222 can be connected with the second covering part 221 and can be respectively arranged in the two air inlet holes 104 to block the two air inlet holes 104, respectively. Of course, the number of protruding parts 222 can not be limited to two, and the number of protruding parts 222 can change with the number of air inlet holes 104, which is not limited in the present embodiment.

[0070] The atomization device 10 provided in the present application can reduce the risk of liquid leakage of the atomization assembly 100 during transportation by respectively inserting the separable first blocking piece 210 and the second blocking piece 220 in the air guide hole 103 and the air inlet hole 104 of the atomization assembly 100, and the first blocking piece 210 and the second blocking piece 220 can block the air guide hole 103 and the air inlet hole 104, respectively, so that the atomized liquid stored in the atomization assembly 100 is not easy to leak to various places of the atomization assembly 100 through the air guide hole 103 and the air inlet hole 104.

[0071] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is made by using the content of the present application specification and drawings, is also included in the patent protection scope of the present application.
