Description

Technical Field

[0001] This application relates to the field of atomizer technology, and in particular to an atomizer and an aerosol generating device. Background Technology

[0002] An atomizer is a device that heats and atomizes an aerosol-generating matrix into an aerosol. The aerosol formed after heating and atomization has a high temperature. When it cools down, it will form condensate and be absorbed inside the atomizer. Some of the condensate will accumulate in the air outlet channel, causing air outlet blockage. Some of the condensate will flow to the air inlet, causing air inlet blockage due to the small size of the air inlet.

[0003] In related technologies, atomizers increase the space inside the atomizer to store condensate. However, when the atomizer is placed at different angles, the condensate can still easily flow into the air outlet and / or air inlet, causing blockage of the atomizer's air passage.

[0014] The thickness of the liquid-absorbing element along the first direction is not greater than 10 mm and not less than 0.5 mm.

[0015] In some embodiments, the atomizer has capillary channels located within the housing, the capillary channels being in fluid communication with both the atomizing core and the liquid-absorbing element.

[0016] In some embodiments, the atomizer further includes a liquid guide, at least a portion of which is located within the atomization chamber, the liquid guide cooperating with the housing to form the capillary channel at least within the atomization chamber.

[0017] In some embodiments, the housing has a mounting post located within the atomizing chamber, and the liquid guide and the mounting post together form the capillary channel.

[0018] In some embodiments, the mounting column includes a first wall and two second walls, the two second walls being located on opposite sides of the first wall and together with the first wall forming a receiving groove.

[0036] In the description of the embodiments in this application, it should be noted that the terms "first direction" and "second direction" are based on the appended... Figure 1 The orientation or positional relationship shown, "third direction" is based on the attached Figure 2 The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0037] This application provides an aerosol generating device; please refer to [link / reference]. Figure 1 and Figure 3 The aerosol generating device includes an atomizer 10 and a power supply component 20, which is electrically connected to the atomizer 10.

[0038] The aerosol generating device is used to produce aerosols for users to inhale or for medical, cosmetic, and other applications. The power supply unit 20 works in conjunction with the nebulizer 10 to supply power to the nebulizer 10 and control its operating status. The power supply unit typically includes a battery 22 for supplying power to the nebulizer 10 and an electronic control board 21 for controlling the heating of the nebulizer 10. The nebulizer 10 is used to heat and atomize the aerosol liquid after being powered on to generate an aerosol.

[0039] Please see Figures 1 to 6 The atomizer 10 of this application embodiment includes a housing 11 and an atomizing core 12 and a liquid suction member 13 disposed in the housing 11. The housing 11 has an atomizing chamber 11a and an air inlet channel 11b and an air outlet channel 11c respectively communicating with the atomizing chamber 11a. The atomizing chamber 11a is located between the atomizing core 12 and the liquid suction member 13, and is in fluid communication with the atomizing core 12 and the liquid suction member 13 respectively.

[0040] The atomizing core 12 is used to heat and atomize the atomizing liquid. The atomizing core 12 is in fluid communication with the atomizing chamber 11a, meaning that the atomizing surface of the atomizing core 12 faces the atomizing chamber 11a, so that the aerosol generated by the heating and atomization of the atomizing liquid is released within the atomizing chamber 11a. Please refer to... Figure 1 The airflow enters the air intake 11b1 of the air intake 11b and enters the atomization chamber 11a. Under the action of the airflow, the aerosol can flow along the airflow path to the air outlet 11c, thereby achieving a better misting effect.

[0041] It is understandable that the temperature of the aerosol generated by the heating and atomization of the atomizing liquid by the atomizing core 12 is generally high. The high temperature aerosol is prone to condensation when it is cooled. The condensate flows along the wall of the atomizing chamber 11a to the liquid suction element 13, and is thus absorbed and stored by the liquid suction element 13.

[0042] The atomizing chamber 11a being located between the atomizing core 12 and the liquid-absorbing component 13 means that there is a certain distance between the atomizing core 12 and the liquid-absorbing component 13. For example, please refer to [link to relevant documentation]. Figure 2 The distance H1 between the atomizing core 12 and the liquid-absorbing element 13 in the first direction is not greater than 10 mm and not less than 2 mm. More preferably, the distance H1 between the atomizing core 12 and the liquid-absorbing element 13 in the first direction can be 5.7 mm.

[0043] The type of absorbent 13 is not limited. For example, the absorbent 13 can be absorbent cotton, which has a porous structure and good liquid storage and absorption capacity. More preferably, the absorbent cotton can be made of polymer cotton.

[0044] The size of the liquid suction element 13 is not limited; for example, please refer to [link to example]. Figure 2The dimension H2 of the liquid suction member 13 along the first direction is not greater than 10 mm and not less than 0.5 mm, so as to ensure that the liquid suction member 13 has good liquid suction capacity without occupying too much space. More preferably, the dimension H2 of the liquid suction member 13 along the first direction can be 3 mm.

[0045] Please see Figure 1 and Figure 3 The housing 11 has a liquid storage chamber 11g located on the side of the atomizing core 12 opposite to the atomizing surface, and the liquid storage chamber 11g is in fluid communication with the atomizing core. The liquid storage chamber 11g is used to store atomizing liquid, and the fluid communication between the liquid storage chamber 11g and the atomizing core 12 means that the atomizing liquid in the liquid storage chamber 11g can flow to the atomizing core 12 so that the atomizing core 12 can heat and atomize the atomizing liquid. In some embodiments, the atomizing liquid in the liquid storage chamber 11g can enter the atomizing chamber 11a through the atomizing core 12 and then be absorbed by the liquid suction member 13. Thus, the liquid suction member 13 can not only absorb the condensate after aerosol condensation, but also absorb the atomizing liquid that has not been heated and atomized.

[0046] Figure 1 and Figure 3 The housing 11 includes a support 112 and an oil reservoir 113. The support 112 has an atomizing chamber 11a and an air inlet channel 11b, with the opening of the atomizing chamber 11a facing the oil reservoir 113. The oil reservoir 113 has an air outlet channel 11c and a liquid storage chamber 113a. The atomizing core 12 is disposed at the liquid outlet of the liquid storage chamber 113a, with the atomizing surface of the atomizing core 12 facing the opening of the atomizing chamber 11a for fluid communication with the atomizing chamber 11a. The support 112 and the oil reservoir 113 are detachably connected, thereby facilitating the assembly and maintenance of the atomizer 10.

[0047] The atomizer 10 in this embodiment includes a housing 11 and an atomizing core 12 and a liquid-absorbing element 13 disposed within the housing 11. The atomizing chamber 11a is located between the atomizing core 12 and the liquid-absorbing element 13. When the atomizer 10 is powered on, the atomizing core 12 is heated and atomized to generate an aerosol. The condensate generated by the high-temperature aerosol cooling in the atomizing chamber 11a can flow along the wall of the atomizing chamber 11a to the liquid-absorbing element 13, where it is absorbed and stored. Similarly, the condensate generated by the high-temperature aerosol cooling in the air outlet channel 11c can also flow from the air outlet channel 11c into the atomizing chamber 11a and be absorbed and stored by the liquid-absorbing element 13. Thus, the condensate in the atomizing chamber 11a will not easily flow into the air inlet channel 11b, causing blockage of the air inlet 11b2, and can also alleviate the problem of condensate blockage in the air outlet channel 11c. Therefore, the atomizer 10 in this embodiment can effectively alleviate the problem of airway blockage caused by condensate.

[0048] In some embodiments, please refer to Figure 3 and Figure 4The atomizer 10 has a capillary channel 10a located inside the housing 11, which is in fluid communication with the atomizing core 12 and the liquid suction element 13.

[0049] A capillary channel 10a refers to a channel that allows the atomized liquid to flow spontaneously within the channel under the action of capillary effect.

[0050] During the heating and atomization process of the atomizing core 12, the condensate stored in the liquid suction member 13 can flow to the atomizing core 12 along the capillary channel 10a under the action of capillary effect, so as to be heated and atomized by the atomizing core 12. This can avoid the problem of condensate accumulation caused by the liquid suction member 13 being unable to absorb condensate due to saturation of the liquid suction volume. In addition, the atomized liquid in the liquid storage chamber 113a can also flow to the liquid suction member 13 through the atomizing core 12 along the capillary channel 10a and be stored in the liquid suction member 13. During the heating and atomization process of the atomizing core 12, the atomized liquid flows back to the atomizing core 12 along the capillary channel 10a, thereby improving the utilization rate of the atomized liquid.

[0051] The location of the capillary channel 10a is not limited; for example, please refer to [link to relevant documentation]. Figure 1 and Figure 3 The housing 11 has an air outlet 11f at one end along the first direction. The atomizing core 12 is located on the side of the atomizing chamber 11a along the first direction close to the air outlet 11f. The liquid suction member 13 is located on the side of the atomizing chamber 11a along the first direction opposite to the atomizing core 12. The air outlet channel 11c is connected to the air outlet 11f. The capillary channel 10a is located on at least one side of the liquid suction member 13 on opposite sides along the third direction, wherein the third direction intersects with the first direction.

[0052] The air outlet 11f refers to the outlet from which aerosols flow from the air outlet channel 11c into the user's mouth.

[0053] The number of capillary channels 10a can be one, located on one side of the opposite sides of the liquid suction member 13 along the third direction; or the number of capillary channels 10a can be two, each located on one side of the opposite sides of the liquid suction member 13 along the third direction. By positioning the capillary channels 10a on at least one side of the opposite sides of the liquid suction member 13 along the third direction, the condensate stored in the liquid suction member 13 can enter the capillary channels 10a more smoothly.

[0054] Preferably, the third direction can be perpendicular to the first direction.

[0055] The structure of the capillary channel 10a is not limited. For example, the capillary channel 10a can be formed in the housing 11, that is, the housing 11 has an atomizing chamber 11a and a capillary channel 10a in fluid communication with the atomizing chamber 11a.

[0056] In other embodiments, the capillary channel 10a may also be formed by two components together; for example, please refer to [reference needed]. Figures 1 to 4 , Figure 6 The atomizer 10 may also include a liquid guide 14, at least a portion of which is located within the atomization chamber 11a. The liquid guide 14 cooperates with the housing 11 to form a capillary channel 10a within the atomization chamber 11a. In other words, the capillary channel 10a is formed by the liquid guide 14 and the housing 11, and at least a portion of the capillary channel 10a is located within the atomization chamber 11a. This allows for a more compact space within the housing 11 and reduces the probability of condensate leaking from the housing 11 and contaminating other components. Figure 2 and Figure 3 In the atomizer 10 shown, a portion of the capillary channel 10a extends to one side of the liquid suction member 13 to improve the fluid communication between the liquid suction member 13 and the capillary channel 10a.

[0057] For example, the liquid guiding member 14 can be spaced apart from the inner wall surface of the atomizing chamber 11a so that a capillary channel 10a is formed at the interval, thereby saving space in the atomizing chamber 11a and making the atomizer 10 thinner and lighter.

[0058] In other embodiments, please refer to Figure 5 and Figure 6 The housing 11 has a mounting post 111 located in the atomizing chamber 11a, and the liquid guiding member 14 can work together with the mounting post 111 to form a capillary channel 10a.

[0059] Mounting post 111 is used to mount liquid guiding component 14, thereby improving the installation stability of liquid guiding component 14.

[0060] The connection method between the liquid guiding component 14 and the mounting post 111 is not limited. For example, please refer to [link to example]. Figure 5 and Figure 6 One end of the liquid guiding component 14 may have a groove, and one end of the mounting post 111 faces the atomizing core 12 and is inserted into the groove. This facilitates the assembly between the liquid guiding component 14 and the mounting post 111 and ensures the installation stability of the liquid guiding component 14.

[0061] The structure of the mounting post 111 is not limited; for example, please refer to [reference needed]. Figure 5 and Figure 6 The mounting column 111 may include a first wall 1111 and two second walls 1112. The two second walls 1112 are located on opposite sides of the first wall 1111 and together with the first wall 1111, they enclose a receiving groove 111a. The liquid guiding member 14 is spaced apart from at least one of the first wall 1111 and the two second walls 1112, so that a capillary channel 10a is formed at the interval.

[0062] In other words, part of the structure of the liquid guiding component 14 is located in the receiving tank 111a and is spaced apart from at least one side wall.

[0063] Figure 6 In the atomizer 10 shown, the liquid guiding element 14 is simultaneously arranged with the first wall 1111 and the two second walls 1112 at intervals. That is, capillary channels 10a are formed between the liquid guiding element 14 and the first wall 1111 and the two second walls 1112 respectively, thereby increasing the amount of condensate that the capillary channels 10a can hold, so as to improve the liquid guiding efficiency.

[0064] In other embodiments, the liquid guiding member 14 may be spaced apart only from the first wall 1111 and in contact with the two second walls 1112; or, the liquid guiding member 14 may be spaced apart from the two second walls 1112 and in contact with the first wall 1111; or, the liquid guiding member 14 may be spaced apart from one of the two second walls 1112 and the first wall 1111.

[0065] In some embodiments, please refer to Figure 3 and Figure 4 Part of the liquid guiding component 14 is located outside the atomizing chamber 11a, and the liquid suction component 13 is located on one side of the liquid guiding component 14. The liquid suction component 13 and the liquid guiding component 14 are spaced apart outside the atomizing chamber 11a so that the spaced part forms a liquid storage gap 10b that is in fluid communication with the capillary channel 10a.

[0066] The liquid storage gap 10b is used to contain condensate and / or atomizing liquid. Exemplarily, the atomizing liquid in the liquid storage chamber 113a flows into the liquid storage gap 10b from the capillary channel 10a, and is then absorbed by the suction element 13 from the liquid storage gap 10b. In other embodiments, when the atomizing core 12 heats up and atomizes, the condensate and / or atomizing liquid in the suction element 13 enters the capillary channel 10a from the liquid storage tank 11e and is heated and atomized into an aerosol by the atomizing core 12. Therefore, by providing a liquid storage gap 10b that is fluidly connected to the capillary channel 10a, the condensate and / or atomizing liquid can be better introduced from the capillary channel 10a into the suction element 13, and the condensate and / or atomizing liquid can also be better introduced from the suction element 13 into the capillary channel 10a.

[0067] For example, please refer to Figure 3 , Figure 4 and Figure 6 On the part of the liquid guiding component 14 located outside the atomizing chamber 11a, a portion of the capillary channel 10a and the liquid storage gap 10b surround the periphery of the liquid guiding component 14 and are interconnected to further improve the liquid guiding effect.

[0068] The distance between the liquid-absorbing component 13 and the liquid-guiding component 14 is not limited. For example, the distance H3 between the liquid-absorbing component 13 and the liquid-guiding component 14 can be no greater than 1 mm, so as to ensure the oil guiding effect without occupying too much space. More preferably, the distance H3 between the liquid-absorbing component 13 and the liquid-guiding component 14 can be 0.15 mm.

[0069] In other embodiments, the liquid suction member 13 may also contact the portion of the liquid guiding member 14 located outside the atomizing chamber 11a, that is, no liquid storage gap 10b is formed between the portion of the liquid suction member 13 and the portion of the liquid guiding member 14 located outside the atomizing chamber 11a.

[0070] For example, the liquid guiding member 14 may have a protruding fixing part located on the side of the liquid suction member 13 near the atomizing chamber 11a and abutting against the liquid suction member 13. That is, the liquid guiding member 14 may also limit the liquid suction member 13 in the first direction. More preferably, the fixing part and the bottom wall of the receiving cavity 11d on the side away from the atomizing chamber 11a in the first direction together fix the liquid guiding member 14 to improve the installation stability of the liquid suction member 13.

[0071] In some embodiments, the liquid guide 14 is an electrode electrically connected to the atomizing core 12. That is, the liquid guide 14 can be an existing electrode in the aerosol generating device. The liquid guide 14 can not only cooperate with the housing 11 to construct a capillary channel 10a in at least the atomizing chamber 11a, but also be used to electrically connect the atomizing core 12 and the power supply assembly 20. In other words, there is no need to add other conductive components, thereby reducing the number of parts in the atomizer 10 and reducing production costs.

[0072] For example, please refer to Figure 3 The liquid guiding component 14 and the heating element of the atomizing core 12 are electrically connected through contact.

[0073] Please see Figure 1 and Figure 3 The power supply assembly 20 includes an electronic control board 21 and a battery 22 electrically connected to the electronic control board 21. The housing 11 has a mounting cavity (not shown in the figure), the electronic control board 21 is located in the mounting cavity, and part of the liquid guide 14 extends into the mounting cavity and is electrically connected to the electronic control board 21, thereby enabling the power supply assembly 20 to supply power to the atomizing core 12.

[0074] In some embodiments, please refer to Figure 1 , Figure 5 and Figure 6 The housing 11 has a receiving cavity 11d that communicates with the atomizing cavity 11a, and the liquid suction member 13 is disposed in the receiving cavity 11d.

[0075] For example, the suction member 13 may be interference-fitted with the receiving cavity 11d.

[0076] An interference fit means that the periphery of the liquid suction member 13 abuts against the side wall of the receiving cavity 11d, so that the liquid suction member 13 is fixed in the receiving cavity 11d and prevents the liquid suction member 13 from loosening under the action of external force.

[0077] It should be noted that the liquid suction component 13 and the receiving cavity 11d are interference fit. This can be a partial structure of the liquid suction component 13 that is interference fit with the receiving cavity 11d, or it can be the entire structure of the liquid suction component 13 that is interference fit with the receiving cavity 11d.

[0078] Please see Figure 2 and Figure 6 The liquid suction member 13 may be spaced apart from at least a portion of the sidewall of the receiving cavity 11d so that a liquid storage tank 11e is formed at the interval.

[0079] The liquid storage tank 11e is used to hold condensate.

[0080] The sidewall of the receiving cavity 11d refers to the sidewall adjacent to the atomizing cavity 11a. In other words, the liquid storage tank 11e is in fluid communication with the liquid suction member 13 and the atomizing cavity 11a respectively. The condensate in the atomizing cavity 11a can flow into the liquid storage tank 11e along the sidewall of the atomizing cavity 11a, and then be absorbed by the liquid suction member 13 from the liquid storage tank 11e. This can alleviate the problem that when the condensate drips directly onto the liquid suction member 13, a liquid film is formed on the surface of the liquid suction member 13, which affects the liquid suction effect of the liquid suction member 13.

[0081] Please see Figure 6 The liquid suction member 13 can be spaced apart from part of the side wall of the receiving cavity 11d and abut against another part of the side wall, thereby both fixing the liquid suction member 13 and improving the liquid suction effect of the liquid suction member 13.

[0082] In other embodiments, the suction member 13 may also be spaced apart from all the sidewalls of the receiving cavity 11d, that is, the liquid storage tank 11e surrounds the periphery of the suction member 13.

[0083] In some embodiments, please refer to Figure 1 The housing 11 has an air outlet 11f at one end along the first direction. The atomizing core 12 can be located on the side of the atomizing chamber 11a along the first direction close to the air outlet 11f. The liquid suction member 13 is located on the side of the atomizing chamber 11a along the first direction opposite to the atomizing core 12. The air outlet channel 11c is connected to the air outlet 11f.

[0084] The air outlet 11f is the outlet for aerosol to flow out of the housing 11. The aerosol in the atomizing chamber 11a flows out from the air outlet 11f along the air outlet channel 11c under the action of airflow.

[0085] The liquid suction element 13 is located on the side of the atomizing chamber 11a opposite to the atomizing core 12 along the first direction. That is, the liquid suction element 13 is located on the side of the atomizing chamber 11a away from the air outlet 11f. The condensate can flow along the first direction away from the air outlet 11f and be absorbed by the liquid suction element 13, thereby preventing the condensate from flowing out of the housing 11 from the air outlet 11f.

[0086] For example, please refer to Figure 1 The air outlet channel 11c has a first communication port 11c1 that communicates with the atomizing chamber 11a. The first communication port 11c1 and the atomizing core 12 can be located on the same side of the atomizing chamber 11a along the first direction.

[0087] In other words, the first connecting port 11c1 is located on the side of the atomizing chamber 11a away from the liquid suction member 13, which prevents the condensate in the atomizing chamber 11a from entering the gas outlet channel 11c. In addition, when the high-temperature aerosol flows through the gas outlet channel 11c, it is easy to form condensate on the side wall of the lower-temperature gas outlet channel 11c. Since the first connecting port 11c1 is located on the side of the atomizing chamber 11a away from the liquid suction member 13, the condensate in the gas outlet channel 11c can flow more smoothly to the atomizing chamber 11a and then be absorbed by the liquid suction member 13, thereby effectively preventing the condensate from clogging the gas outlet channel 11c.

[0088] Please see Figure 1 and Figure 5 The housing 11 has a receiving cavity 11d communicating with the atomizing cavity 11a. The liquid suction member 13 is disposed in the receiving cavity 11d. The liquid suction member 13 is spaced apart from at least a portion of the side wall of the receiving cavity 11d so that a liquid storage tank 11e is formed at the interval. The liquid storage tank 11e has a second communication port 11e1 communicating with the atomizing cavity 11a on the side of the liquid storage tank 11e close to the atomizing cavity 11a along the first direction. At least a portion of the second communication port 11e1 of the liquid storage tank 11e can face the first communication port 11c1.

[0089] The second connection port 11e1 of at least part of the liquid storage tank 11e can face the first connection port 11c1, which means that the first connection port 11c1 and the second connection port 11e1 are located on opposite sides of the atomizing chamber 11a along the first direction. On the projection plane perpendicular to the first direction, the projection area of ​​the second connection port 11e1 at least partially coincides with the projection area of ​​the first connection port 11c1. In other words, when the condensate in the air outlet channel 11c flows into the atomizing chamber 11a from the first connection port 11c1, it flows at least partially toward the second connection port 11e1.

[0090] The size H4 of the liquid storage tank 11e is not limited. For example, it can be not less than 10 mm. That is, the distance between the liquid suction member 13 and the side wall of the receiving cavity 11d along the second direction is not less than 10 mm, so that the liquid storage tank 11e has a better liquid guiding effect.

[0091] Preferably, please refer to Figure 1 and Figure 2 The atomizing chamber 11a is along the first direction, and the sidewall located between the second connecting port 11e1 and the first connecting port 11c1 can be arc-shaped to better guide the condensate to the suction member 13 and / or the storage tank 11e.

[0092] In some embodiments, please refer to Figure 1 The air inlet channel 11b and the air outlet channel 11c can be located on opposite sides of the atomizing chamber 11a along the second direction, wherein the second direction intersects the first direction, so that the aerosol formed in the atomizing chamber 11a is fully mixed with the air, thereby reducing the formation of condensate. More preferably, the second direction can be perpendicular to the first direction.

[0093] For example, please refer to Figure 1 , Figure 5 and Figure 6 The air intake channel 11b has a third connecting port 11b1 that communicates with the atomizing chamber 11a. The third connecting port 11b1 is located between the atomizing core 12 and the liquid suction member 13. That is, the height of the third connecting port 11b1 is higher than that of the liquid suction member 13, which can effectively prevent condensate from entering the air intake channel 11b from the third connecting port 11b1 and thus blocking the air intake port 11b2 of the air intake channel 11b.

[0094] For example, please refer to Figure 1 On the projection plane perpendicular to the first direction, the projection of the atomizing core 12 and the projection of the third connecting port 11b1 are offset. That is, in the first direction, the third connecting port 11b1 avoids the atomizing surface of the atomizing core 12, and in the second direction, the projection of the third connecting port 11b1 and the projection of the atomizing core 12 do not coincide. This can prevent the aerosol generated by the atomization of the atomizing core 12 from directly rushing towards the third connecting port 11b1 along the first direction, causing blockage of the air intake channel.

[0095] Please see Figure 1 and Figure 5 The atomizing chamber 11a has a first side X1 and a second side X2 opposite to each other along a first direction. The atomizing core 12 is located on the first side X1. The housing 11 includes a protrusion 114 located inside the atomizing chamber 10a and with one end facing the first side X1. At least a portion of the air intake channel 11b is located inside the protrusion 114. A third connecting port 11b1 is provided at the end of the protrusion 114 facing the first side X1. The protrusion 114 can extend from the second side X2 of the atomizing chamber 11a to the first side X1, and the protrusion 114 and the inner wall surface of the atomizing chamber 11a located on the periphery of the protrusion 114 are spaced apart.

[0096] The first side X1 of the atomizing chamber 11a refers to the side of the atomizing chamber 11a that is close to the air outlet 11f along the second direction, and the second side X2 is the side of the atomizing chamber 11a that is away from the air outlet 11f along the second direction. Under the action of gravity, the condensate tends to flow along the inner wall of the atomizing chamber 11a from the first side X1 to the second side X2.

[0097] The protruding post 114 extends from the second side X2 of the atomizing chamber 11a towards the first side X1. That is, the protruding post 114 protrudes from the inner wall surface of the atomizing chamber 11a located on the second side X2, preventing condensate from accumulating on the second side X2 and flowing into the air intake channel 11b from the third connecting port 11b1. The protruding post 114 is spaced apart from the inner wall surface of the atomizing chamber 11a located around its periphery; that is, the outer wall surface of the protruding post 114 does not contact the inner wall surface of the atomizing chamber 11a, preventing condensate from flowing into the air intake channel 11b along the inner wall surface of the atomizing chamber 11a.
