[0001] CROSS REFERENCE
[0002] This application claims the priority to Chinese Patent Application No. 202310943900.9 filed on July 28, 2023, and entitled “Atomizing Apparatus and Atomizing Device” , which is hereby incorporated by reference in its entirety.FIELD
[0003] Example embodiments of the present disclosure generally relate to the field of atomizers, and in particular, to an atomizing apparatus and an atomizing device including the atomizing apparatus.BACKGROUND
[0004] The atomizing apparatus is a key member for converting aerosol precursor, such as liquid tobacco product, into an inhalable aerosol. When the conventional atomizing apparatus supplies power, the atomizing core therein may heat and atomize the liquid aerosol precursor to generate aerosol for inhalation. The atomizing core is also commonly referred to as a heating element or a heating component. Common heating elements include heating wire and ceramic heating plates, which heat liquid tobacco products to generate atomization. The atomizing chamber is used for temporarily containing the aerosol formed after the aerosol precursor is heated by the heating element. The conventional atomizing apparatus makes it easy to create a vortex in the atomizing process, making it difficult for the atomized aerosol to be discharged, and the problems that condensate formed by the aerosol after condensation easily block an air inlet passage and the like.SUMMARY

[0034] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited by embodiments set forth herein. Rather, these embodiments are provided to make the present disclosure more thorough and complete, and can fully convey the scope of the present disclosure to those skilled in the art.
[0035] As used herein, the term “comprising” and variations thereof means open inclusive, i.e., “including but not limited to” . Unless specifically stated, the term “or” means “and / or” . The term “based on” means “based at least in part on” . The terms “one example embodiment” and “some embodiments” mean “at least one example embodiment” . The term “another embodiment” means “at least one further embodiment” . The terms “first, ” “second, ” and the like may refer to different or identical objects.
[0036] The conventional atomizing apparatus generally heats an aerosol precursor by heating an atomizing core, so that the aerosol precursor is atomized in an atomizing cavity to form an aerosol. Under the suction action at the air outlet, the airflow enters from the air inlet and passes through the atomization cavity to drive the aerosol to flow to the air outlet, so that aerosol which may be inhaled by a smoker is formed.
[0037] However, in the working process of the atomizing apparatus, the airflow direction entering the atomizing cavity determines the flow rate of the aerosol. The conventional atomizing apparatus arranges an air inlet passage of an air inlet communicating with an atomizing cavity in a direction perpendicular to the atomizing surface of the atomizing core, and the air inlet passage is located below the atomizing core. Under the action of suction, the airflow enters the atomization cavity in a direction perpendicular to the atomizing surface of the atomizing core, so that a vortex is formed, and the vortex directly affects the flow rate of the aerosol, so that the efficiency of actually taking away the aerosol by the airflow is reduced. If the formed aerosol cannot be discharged out of the atomizing apparatus in time, in the flowing process, the aerosol is easily condensed inside the atomizing apparatus due to the temperature change of the airflow passage, so that the remaining aerosol is deposited in the atomizing cavity during suction and forms condensate. In one aspect, this may lead to waste of high value aerosol precursor. On the other hand, this may cause the condensate to leak from the air inlet or block the air inlet, causing the atomizing apparatus to fail to work normally.
[0038] In addition, conventional atomizing apparatus arranges the air inlet on the side wall of the housing adjacent to the atomizing chamber. Although this arrangement of the air inlet may improve the efficiency of the flow of the aerosol by changing the flow direction of the airflow entering the atomization cavity, since the air inlet is arranged close to the atomization cavity, when the atomizing apparatus is oriented approximately horizontally during use, the condensate may leak or block the air inlet from the air inlet, so that the atomizing apparatus cannot work normally.
[0039] Embodiments of the present disclosure provide an atomizing apparatus to solve or at least partially solve the above problems or other potential problems existing in conventional atomizing apparatuses. The principles of the present disclosure will be described in detail below with reference to FIGS. 1 to 6. Referring to FIG. 1 and FIG. 2, FIG. 1 illustrates a schematic perspective view of an atomizing apparatus according to some embodiments of the present disclosure. FIG. 2 illustrates a schematic side view of an atomizing apparatus according to some embodiments of the present disclosure. As shown in FIGS. 1 and 2, the atomizing apparatus 100 described herein generally includes a housing 101 and an atomizing core 103 arranged in housing 101. In some embodiments, the atomizing apparatus 100 may further include members such as a suction member 107 and a connecting member 1016, for example, the suction member 107 may be detachably connected to an upper end of the housing 101 to facilitate replacement. The connecting member 1016 is connected to the lower end of housing 101, and the connecting member 1016 is a detachable member for connecting a power supply for power supply, so as to facilitate installation or disassembly, which will be further described below with reference to the accompanying drawings.
[0040] FIG. 3 illustrates an exploded schematic diagram of an atomizing apparatus according to some embodiments of the present disclosure. As shown in FIG. 1 to FIG. 3, in some embodiments, the housing 101 is a cylindrical structure or a prismatic structure extending along the direction A (hereinafter referred to as the axial direction A) or any other suitable shape, which is not limited in embodiments of the present disclosure. The housing 101 has a liquid reservoir 1011 and an airflow passage 102 therein. The liquid reservoir 1011 is configured to accommodate an aerosol precursor, and the aerosol precursor may include tobacco tar or liquid medicine, which is not limited in embodiments of the present disclosure. In the case where the aerosol precursor includes cooking fume, the liquid reservoir 1011 may also be referred to as an oil tank.
[0041] The atomizing core 103 is arranged at one end (hereinafter referred to as atomizing end) of the liquid reservoir 1011 in the axial direction A. The atomizing core 103 includes an atomizing surface. The atomizing surface may contact the aerosol precursor, thereby heating the aerosol precursor into an aerosol. To facilitate atomization of the aerosol precursor, a microporous and / or microchannel structure adjacent to the atomizing surface may be included in the atomizing core 103. Micropore and / or microchannel structures may accommodate a small amount of aerosol precursor to facilitate formation of aerosol by the aerosol precursor. Of course, as long as the aerosol precursor may be formed into an aerosol in an appropriate manner, the atomizing core 103 is possible in any appropriate manner or structure, which is not limited herein.
[0042] In some embodiments, in order to facilitate replenishment of the aerosol precursor, the top of the liquid reservoir 1011 may have a liquid feeding port 1019. The opening direction of the liquid feeding port 1019 may be toward the suction member 107. In other words, the liquid feeding port 1019 is located at a liquid feeding end opposite to the atomizing end in the axial direction A. In some embodiments, the opening position of the liquid feeding port 1019 may be arranged on the axis of the atomizing apparatus 100, thereby facilitating the suction member 107 to seal the liquid feeding port 1019. Of course, it should be understood that the opening position of the liquid feeding port 1019 may also be arranged away from the axis of the atomizing apparatus 100, which is not limited in embodiments of the present disclosure. The airflow passage 102 of the atomizing apparatus according to embodiment of the present disclosure is arranged close to the side wall of the housing 101, and the liquid reservoir1011 is arranged adjacent to the airflow passage 102, so that the space of the liquid reservoir1011 may be maximized, which will be further described below.
[0043] In some embodiments, as shown in FIG. 3, the atomizing apparatus 100 further includes a bracket 104. The bracket 104 is configured to fix the atomizing core 103. The housing 101 may also include a body 1014. The liquid reservoir 1011 mentioned above is formed in the body 1014. The bracket 104 is located inside the body 1014. In some embodiments, the bracket 104 and the body 1014 may be integrally formed. In some alternative embodiments, the bracket 104 and the body 1014 may also be fixed together in a clamping manner, which is not limited in embodiments of the present disclosure. The bracket 104 seals liquid reservoir 101, and an upper end of the bracket 104 forms at least a portion of an atomizing end of the liquid reservoir 1011. An atomizing core 103 is fixed to a lower end of the bracket 104. In this way, the atomizing core 103 is sealingly coupled to the atomizing end of the liquid reservoir 1011 in the axial direction A. The liquid reservoir 1011 provides an aerosol precursor to the atomizing core 103 and contacts an atomizing surface of the atomizing core 103 to heat the aerosol precursor into an aerosol and release the aerosol into the airflow passage 102. It should be understood that “upper” and “lower” mentioned herein refer to the case where the extension direction (i.e., axial direction) of the housing 101 coincides with the gravity direction. It should be understood that in the case that the housing 101 in the atomizing apparatus is in other orientations, the members or portions having the “upper” and “lower” relationship may have other positional relationships.
[0044] The airflow passage 102 includes an air outlet 1012 and an air inlet 1013. Under the suction action of the air outlet 1012, the airflow may enter from the air inlet 1013 and carry the aerosol along the airflow passage 102 to be discharged from the air outlet 1012. The air outlet 1012 and the air inlet 1013 are located at two opposite ends of the housing 101 in the axial direction A. For example, when the extension direction of the housing 101 is oriented in the vertical direction (i.e., consistent with the gravity direction) , the air outlet 1012 is located at the upper end of the housing 101, and the air inlet 1013 is located at the lower end of the housing 101. In this way, the spatial layout of the housing 101 may be more reasonable, thereby improving user experience.
[0045] In some embodiments, the atomizing core 103 may be arranged in the bracket 104 such that the atomizing surface thereof is at a second predetermined angle with respect to the axial direction A. The second predetermined angle ranges from 30° to 90°. For example, as shown in FIG. 3, the atomizing core 103 may be arranged such that the atomizing surface is perpendicular to the axial direction A, that is, the atomizing surface may be perpendicular to the axial direction A. Of course, in some alternative embodiments, the atomizing surface is arranged at other inclined angles with respect to the axial direction A, for example, the atomizing surface may also be arranged at an angle of 45°or 60° with respect to the axial direction A. In this way, the formed aerosol may be more fully taken away and discharged, thereby improving the utilization rate of the aerosol precursor and reducing the formed condensate.
[0046] The above arrangement of the atomizing surfaces may be achieved by adjusting the structure of the bracket 104 or the arrangement in the housing 101. For example, in some embodiments, the bracket 104 may be arranged in a direction perpendicular to the axial direction A, or may be arranged at a second predetermined angle with respect to the direction A, i.e., obliquely arranged. For example, in some embodiments, the bracket 104 may be generally obliquely arranged such that the atomizing surface of the atomizing core 103 is obliquely arranged relative to the axial direction A. In some alternative embodiments, the bracket 104 is arranged generally perpendicular to the axial direction A, while only the portion of the bracket 104 for coupling the atomizing core 103 is arranged obliquely to the axial direction A, such that the atomizing surface of the atomizing core 103 is arranged obliquely to the axial direction A.
[0047] In some embodiments, to facilitate assembly of members such as the bracket 104, the housing 101 may further include an end seat 1015 coupled to the body 1014. The end seat 1015 is detachably coupled at an end of the body 1014 in the axial direction A. For example, the end seat 1015 may have an opening end and an air inlet end in the axial direction A. The air inlet 1013 mentioned above is located at the air inlet end. In some embodiments, the inner wall of the opening end of the end seat 1015 has a coupling portion for connecting with the outer wall of the end of the body 1014, so that the end seat 1015 is detachably mounted to the end of the body 1014. In some embodiments, the air inlet end of the end seat 1015 may be arranged with a connecting member 1016. The connecting member 1016 may include a connecting portion 1017 for detachably coupling a battery or a power source to supply power to the atomizing core 103 at least through the battery or the power source. In some alternative embodiments, the air inlet end of the end seat 1015 may not include the connecting member 1016. In some embodiments, the housing 101 or the atomizing apparatus 100 may not include the end seat 1015, which will be further described below.
[0048] The suction member 107 mentioned above may also be referred to as a mouthpiece, and the suction member 107 is used to cooperate with a mouth of a user and generate suction required for airflow flow in the atomizing apparatus 100. In some embodiments, the suction member 107 is detachably arranged at an end of the air outlet 1012 of the housing 101. In this way, the suction member 107 may be conveniently replaced when needed, thereby improving user experience. For example, if the suction member 107 is used for too long time and is damaged or aged, the user may directly disassemble and replace the new suction member 107, thereby improving the use time limit of the atomizing apparatus 100 and improving the user experience.
[0049] In some embodiments, the suction member 107 includes a suction passage 1071 and a sealing member 1072, and the suction passage 1071 communicates with the airflow passage 102 through the air outlet 1012. When the suction member 107 is connected to the housing 101, the sealing member 1072 sealingly covers the liquid inlet 1019 of the liquid reservoir 1011. After the suction member 107 is removed from the housing 101, the liquid feeding port 1019 may be exposed, thereby facilitating the user to add the aerosol precursor into the liquid reservoir 1011. In some embodiments, the sealing member 1072 may be made of rubber or silicone to effectively seal the liquid feeding port 1019, which is not limited in embodiments of the present disclosure.
[0050] In some embodiments, the suction member 107 may also be integrated on the housing 101 in an appropriate manner. For example, by reasonably arranging the structure and shape of the housing 101, the suction member 107 may be integrally arranged at one end of the air outlet 1012 of the housing 101, thereby improving the integration level of the atomizing apparatus 100.
[0051] In some embodiments, as shown in FIG. 3, the atomizing apparatus 100 may further include a base 105. The base 105 and the atomizing core 103 and the bracket 104 mentioned above may also be referred to as an atomizing assembly. In some embodiments, the atomizing assembly may also be provided in the form of an integral module, so as to be arranged on the housing 101 as a whole, thereby improving the modularity of the atomizing apparatus 100 and facilitating assembly. In some embodiments, the base 105 may be coupled to the end seat 1015 of the housing 101 and located on a side of the atomizing core 103 away from the liquid reservoir 1011. When the base 105 is coupled to the inside of the end seat 1015 and the end seat 1015 is coupled to the body 1014, the end of the base 105 abuts against the lower end of the bracket 104, so that the base 105 surrounds the atomizing core 103 and the bracket 104 to form an atomizing chamber, that is, the atomizing chamber 1021 forming the airflow passage 102. The atomizing chamber 1021 is actually a section of the airflow passage 102 in the extending direction. The atomizing core 103 causes the aerosol precursor to form an aerosol by heating and is released into the atomizing chamber 1021. The base 105 may be attached to the body 1014 in a suitable manner. For example, in some embodiments, the base 105 may be connected to the body 1014 in a snap-fit manner, so that it is convenient to disassemble. Of course, it should be understood that the connection manner of the base 105 and the body 1014 is not limited thereto, and any other suitable connection manner may be used, including but not limited to: threaded connection, bonding, welding or interference fit. In the foregoing embodiments in which the housing 101 or the atomizing apparatus 100 does not include the end seat 1015, the base 105 may be provided with contacts for directly connecting with a battery or a power source to power the atomizing core 103.
[0052] In some embodiments, the base 105 has a circumferential wall 1051 and a liquid collecting wall 1052. An outer side of the circumferential wall 1051 is sealingly coupled to an inner wall of the housing 101. For example, as mentioned above, the base 105 may be connected to the inner wall of the body 1014 by using the circumferential wall 1051 in a snap-fit manner. The liquid collecting wall 1052 is located inside the base 105, adjacent to one portion of the circumferential wall 1051, and connected to the other portion of the circumferential wall 1051 to form a liquid collecting space with an open end. When the base 105 is coupled to the body 1014, the opening direction of the liquid collecting space points to the atomizing core 103, and the projection of the liquid collecting space in the axial direction A may cover the airflow passage 102 on one side of the air outlet 1012 and at least a portion of the atomizing core 103. In this way, the liquid collecting space can effectively collect the condensate formed by the aerosol in the airflow passage 102, and prevent the condensate from blocking the air inlet 1013 or leaking from the air inlet 1013.
[0053] In addition, the liquid collecting wall 1052 forming the liquid collecting space and the circumferential wall 1051 defines a portion of the airflow passage 102 and the air inlet 1013, and a portion of the airflow passage 102 not covered by a projection of the liquid collecting space in the axial direction A is located on an upstream side of the airflow direction of the atomizing core 103. That is, it is difficult for the aerosol to reach the portion and thus does not form condensate on the portion, thereby effectively preventing the condensate of the aerosol from leaking from the portion of the airflow passage 102 to the air inlet 1013.
[0054] In some embodiments, as shown in FIG. 3, a liquid collecting member 106 may be arranged in the liquid collecting space. The liquid collecting member 106 may include any suitable material such as liquid absorbing cotton. In this way, when the condensate of the atomizing apparatus 100 reaches the liquid collecting space, the liquid collecting member 106 may absorb the condensate, thereby preventing the condensate from leaking from the liquid collecting space again.
[0055] The components and the connection relationship between them are described above in terms of the structure of the atomizing apparatus 100, and the atomizing apparatus 100 of the present disclosure will be described below in terms of a line along the airflow passage 102.
[0056] FIG. 4 to FIG. 6 illustrate schematic structural diagrams of airflow passages according to different embodiments of the present disclosure, and these schematic diagrams mainly differ in a portion of the airflow passage 102 adjacent to the air inlet 1013 (hereinafter referred to as an air inlet end 1022) .
[0057] In some embodiments, as shown in FIG. 4 to FIG. 6, the airflow passage 102 of the atomizing apparatus 100 includes an air inlet section 1022, an air outlet section 1023, and the atomizing chamber 1021 mentioned above. The air inlet section 1022 is a passage communicating the air inlet 1013 and the inlet end of the atomizing chamber 1021. The air outlet section 1023 is a passage communicating the air outlet 1012 and the outlet end of the atomizing chamber 1021. In some embodiments, the air inlet 1013 may be arranged at the center of the air inlet end of the end seat 1015. Of course, it should be understood that the air inlet 1013 may also be arranged at any other suitable position of the air inlet section, which is not limited herein. In some embodiments, the atomizing apparatus further includes a resting table 1020 protruding at least partially outward from a circumferential outward surface of the housing 101 adjacent to the outlet section 1023 and extending for a length in the axial direction. That is, the air outlet section 1023 may be radially arranged between the resting table 1020 and the liquid reservoir 1011. The rest table 1020 may be used to prevent the atomizing apparatus from rolling on the object when the atomizing apparatus rests on the object. The outer surface of the resting table 1020 (i.e., the surface contacting the object) may have a planar shape. In some alternative embodiments, the outer surface of the rest table 1020 may also be any one or a combination of curved surfaces, corrugated surfaces, toothed surfaces and frosted surfaces. In some embodiments, the resting table 1020 may extend from an end of the housing 101 having the air outlet 1012 to an end having the air inlet 1013. In some alternative embodiments, the resting table 1020 may also extend partially between the two ends. In some embodiments, the resting table 1020 may also have a plurality of sub-portions separated from each other in the axial direction A.
[0058] As shown in FIG. 4 and FIG. 5, in some embodiments, the air inlet section 1022 has a bent structure as a whole. Specifically, the air inlet section 1022 may be generally divided into two portions, i.e., a first air inlet section and a second air inlet section. The first air inlet section is defined by the liquid collecting wall 1052 and a portion of the circumferential wall 1051. The second air inlet section is defined by a bracket 104 and a liquid collecting wall 1052.
[0059] Specifically, the first air inlet section extends from the air inlet 1013 in a first direction, and the first direction is at a predetermined angle to the axial direction A. The predetermined angle may range from 0° to 60°. For example, the predetermined angle may be 30° or 45°, which is not limited in embodiments of the present disclosure. By changing the structure of the circumferential wall 1051 and the liquid collecting wall 1052, the air inlet direction of the first air inlet section may be adjusted. By arranging the liquid collecting wall 1052 obliquely to the circumferential wall 1051 on one side of the first air inlet section, the circumferential wall 1051 is arranged along the axial direction A or the inner side of the circumferential wall 1051 is arranged obliquely with the liquid collecting wall 1052, so that the first air inlet end is arranged obliquely in the direction shown in FIG. 4. In this way, the flow of the airflow entering from the air inlet 1013 may be facilitated, and the generation of vortex is prevented. In some alternative embodiments, as shown in FIG. 5, the liquid collecting wall 1052 may also be arranged obliquely to the axial direction A, and the circumferential wall 1051 may be arranged along the axial direction A, so as to form a gradually reduced air inlet end along the air flow direction, thereby ensuring the air inlet amount and making the spatial layout of the housing 101 more reasonable. In some alternative embodiments, as shown in FIG. 6, the liquid collecting wall 1052 and the circumferential wall 1051 may also be arranged along the axial direction A for spatial layout, so that the angle between the first air inlet end and the axial direction A is 0°.
[0060] The second air inlet section is arranged between the first air inlet section and the inlet end of the atomizing chamber 1021 along the second direction, and an included angle between the second direction and the first direction is between 0° and 120°. For example, the included angle between the two may be 30°, 45°, 60° or 90°. As shown in FIG. 4 and FIG. 5, by arranging an inclined structure, a chamfered structure or an arc structure at the corner of the bracket 104 of the adjacent liquid collecting wall 1052, the airflow direction and path of the second air inlet section may be adjusted. In this way, the flow direction of the air inlet airflow may be further optimized, generation of vortices and the like is avoided, and therefore the airflow flow speed is improved. Of course, in some alternative embodiments, as shown in FIG. 6, the corner of the bracket 104 may not be provided with the inclined structure, the chamfered structure or the circular arc structure, so as to facilitate processing. In addition, as mentioned above, since the air inlet section 1022 is arranged on the upstream side of the atomizing core 103 in the airflow direction, the aerosol does not flow to this section, and thus no condensate is formed in this section. Therefore, this arrangement may effectively avoid leakage of condensate from the air inlet 1013.
[0061] In some embodiments, as shown in FIG. 4 to FIG. 6, the inlet end of the atomizing chamber 1021 communicates with the outlet end of the second air inlet section, and the outlet end of the atomizing chamber 1021 communicates with the air outlet section 1023, and the inlet end and the outlet end of the atomizing chamber 1021 are arranged at two ends of the atomizing core 103 in the radial direction R, so that the airflow flows between the inlet end and the outlet end (i.e., the atomization end 1021) in the airflow direction F, and no vortex is generated, thereby more effectively taking away the aerosol.
[0062] In some embodiments, as shown in FIG. 4 to FIG. 6, the airflow direction F in the atomizing chamber 1021 may flow parallel to the atomizing surface, that is, an angle between the airflow direction F and the atomizing surface may be approximately 0°. Of course, the solution according to embodiments of the present disclosure is not limited thereto, for example, in some alternative embodiments, the airflow direction F and the atomizing surface may be at other non-zero angles less than 90°.
[0063] In some embodiments, as shown in FIGS. 4 to 6, the air outlet section 1023 of the airflow passage 102 is adjacently arranged on one side of the liquid reservoir 1011 along the radial direction R. In one aspect, this arrangement can maximize the space of the liquid reservoir 1011. On the other hand, the projection of the liquid collecting space in the axial direction A can cover the air outlet section 1023. In this way, even if the aerosol flowing in the air outlet section 1023 is condensed to generate condensate, the generated condensate can completely enter the liquid collecting space and be absorbed by the liquid collecting member 106 therein, thereby effectively avoiding the risk of the condensate blocking the airflow passage and the air inlet 1013, thereby improving the reliability and user experience of the atomizing apparatus 101. The airflow flow direction in the air outlet section 1023 is parallel to the axial direction A. In some embodiments, the outlet end of the air outlet section 1023 may also adopt an inclined arrangement or an arc arrangement of the second air inlet section, thereby preventing the flowing air from generating a vortex at a right angle and affecting the flow rate.
[0064] In some embodiments, as shown in FIG. 4 to FIG. 6, in the case that the connecting member 1016 is arranged at the air inlet end of the end seat 1015, in order to facilitate the circulation of the airflow, at least one lateral air inlet 1018 may be arranged on the connecting member 1016. The lateral air inlet 1018 is arranged on a radial sidewall of the connecting portion 1017. The air inlet 1013 communicates with the outside through at least one lateral air inlet 1018 to obtain air to meet the air inlet amount of the atomizing apparatus 100. In some embodiments, the connecting member 1016 may include two lateral air inlets 1018 symmetrically arranged on a radial side wall of the connecting portion 1017. In this way, the air inlet amount can be ensured while ensuring the connection strength of the connection portion 1017. In some alternative embodiments, the connecting member 1016 may also include one or more lateral air inlets 1018 on the radial side wall of the connecting portion 1017, which is not limited in embodiments of the present disclosure.
[0065] As mentioned above, according to the atomizing apparatus 100 of the present disclosure, under the action of the suction force of the air outlet 1019, the airflow enters the airflow passage 102 from the air inlet 1013 through the lateral air inlet 1018, and is discharged from the air outlet 1019 after the atomizing chamber effectively takes away the generated aerosol along the airflow direction F. In this way, the vortex formed by the airflow in the airflow passage 102 is effectively reduced, the outflow rate of the aerosol is improved, and the user experience is improved. In addition, the inlet end and the outlet end of the atomizing chamber 1021 are respectively arranged at two ends of the atomizing core 103 in the radial direction. On one hand, this facilitates the angle between the airflow direction F and the atomizing surface to be less than 90°, thereby effectively avoiding generation of vortex. On the other hand, by arranging and reasonably arranging the liquid collecting space, the formed condensate can effectively enter the liquid collecting space without entering the air inlet section 1022 and the air inlet 1013, thereby avoiding the risk that the air inlet 1013 is blocked and the condensate is leaked, and further improving the user experience.
