[0034] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0035] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0036] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0037] The atomizer core assembly provided in the present application includes an atomizer hood, an atomizer core support and an atomizer core body. The atomizer hood and the atomizer core support are assembled in a first direction; the atomizer core body is arranged in an atomizer cavity inside the atomizer hood support, and the atomizer cavity is through in the first direction; the atomizer hood includes a first slot body and a first air pipe, and the first air pipe is passed through the first slot body in the first direction, the open end of the first slot body abuts against the atomizer core support, and one end of the first air pipe that passes through the first slot body protrudes relative to the bottom wall of the first slot body and can be connected to the atomizer cavity. When the atomizer core assembly is assembled in the atomizer, the end of the first air pipe located outside the first slot body can be connected to the suction nozzle of the atomizer, the atomizer core body heats and atomizes the atomization matrix, and generates an aerosol, and the aerosol moves to the suction nozzle along with the suction airflow for the user to inhale. Among them, since one end of the first air tube is located in the first groove body and protrudes relative to the bottom wall of the first groove body, when condensate formed by aerosol adheres to the inner wall of the first groove body, even if the entire atomizer is inverted (for example, rehydration is performed from the bottom), the condensate will not flow directly into the first air tube, which can effectively prevent the condensate from leaking from the mouthpiece and affecting the user's normal inhalation.

[0038] Some embodiments of the atomizer core assembly and the atomizer provided by the present application are described below with reference to the accompanying drawings.

[0039] In an embodiment of the first aspect of the present application, an atomizer core assembly 100 is provided, such as Figure 1 and Figure 2 As shown, the atomizer core assembly 100 includes an atomizer cover 11, an atomizer core support 12, and an atomizer core body 13. The atomizer cover 11 includes a first slot body 111 and a first air pipe 112 extending through the first slot body 111. The first slot body 111 and the first air pipe 112 both extend along a first direction. A portion of the first air pipe 112 extends into the first slot body 111 and is sealed to the bottom wall of the first slot body 111. Another portion of the first air pipe 112 extends out from an end of the first slot body 111 away from the open end 1111. The end of the first air pipe 112 located outside the first slot body 111 can be connected to the suction nozzle 211 of the atomizer 200 to form a channel for supplying air to the suction nozzle 211. The atomizer core support 12 has an atomizing cavity 121 extending in a first direction. One end of the atomizer core support 12 in the first direction is connected to the open end 1111 of the first groove 111. The atomizer core body 13 is disposed in the atomizing cavity 121 so that when the atomizer core assembly 100 is assembled in the atomizer 200, Figure 3In the example, the atomizing matrix entering the atomizing chamber 121 is heated and atomized by the atomizing core body 13 to generate an aerosol. When the user performs an inhalation action through the suction nozzle 211, a negative pressure is generated in the atomizing chamber 121, and the aerosol generated by the atomization moves toward the suction nozzle 211 with the suction airflow under the action of the negative pressure for the user to inhale. Among them, in the first trough body 111, the first air pipe 112 protrudes relative to the bottom wall of the first trough body 111, that is, in the first direction, one end of the first air pipe 112 located in the first trough body 111 is no longer on the same plane as the bottom wall of the first trough body 111, so as to prevent the condensate in the first trough body 111 from flowing into the first air pipe 112 along the inner wall surface. Among them, when the atomizing core assembly 100 is assembled in the atomizer 200, as Figure 3 In the example in FIG, the first direction is the height direction of the atomizer 200 .

[0040] It is understood that during long-term use, condensate formed by aerosol condensation is likely to form inside the atomizer core assembly, and this condensate usually adheres to the inner wall surface. In actual use, the atomizer may be inverted, such as during storage and transportation, or when the user turns the atomizer bottom upwards for refilling. Condensate adhering to the inner wall surface of the atomizer core assembly will flow towards the nozzle under the action of gravity.

[0041] In this embodiment, the structure of the atomizer core assembly is improved. By setting one end of the first air tube 112 that penetrates the first groove body 111 to protrude relative to the bottom wall of the first groove body 111, when the atomizer core assembly 100 is inverted along with the atomizer 200 as a whole, condensate attached to the inner wall is blocked by the outer wall of the first air tube 112 when it flows into the first groove body 111, preventing the condensate from directly entering the first air tube 112. In addition, the condensate is prevented from flowing toward the suction nozzle 211, which can effectively prevent leakage at the suction nozzle 211 and improve the user experience.

[0042] It should be noted that in this embodiment, the atomizing matrix includes but is not limited to a matrix liquid. The first trough 111 and the first air pipe 112 of the atomizing cover 11 can be two separate structures, assembled into one by a corresponding connection method. Of course, the first trough 111 and the first air pipe 112 can also be an integrally molded structure. In actual application, they can be designed and processed according to specific usage requirements. When the atomizing core assembly 100 is assembled in the atomizer 200, the atomizing core body 13 can be electrically connected to the power supply device 22 of the atomizer 200 through a lead or pin structure to power the atomizing core body 13.

[0043] In a further embodiment of the present application, Figure 1 and Figure 2As shown, the first air pipe 112 of the atomizer hood 11 includes an inner pipe section 1121 and an outer pipe section 1122 arranged in sequence in the first direction. The inner pipe section 1121 is located in the first slot body 111 to be opposite to the atomizing chamber 121 of the atomizer core support 12, so that the aerosol generated in the atomizing chamber 121 can enter the first air pipe 112 through the inner pipe section 1121; the outer pipe section 1122 is located on the end of the first slot body 111 away from the open end 1111, and is used to connect with the suction nozzle 211 of the atomizer 200, so that the aerosol in the first air pipe 112 can be discharged from the suction nozzle 211 for inhalation by the user. Figure 2 and Figure 4 As shown, in the first direction, the length of the inner tube section 1121 is less than the length of the side wall of the first tank body 111, that is, the inner tube section 1121 is completely located inside the first tank body 111, so that there is a certain distance between the inner tube section 1121 and the atomization chamber 121 in the first direction, preventing the inner tube section 1121 from directly contacting the atomizer core support 12 and causing condensate to directly enter the inner tube section 1121.

[0044] It is understood that condensate usually adheres to the inner wall surface and flows along the inner wall surface under the action of gravity. Through the provision of the inner tube segment 1121 in this embodiment, when the atomizer core assembly 100 is inverted, the condensate on the inner wall of the atomizer chamber 121 will not directly contact the inner tube segment 1121 when flowing to the first tank body 111, but will continue to flow along the inner wall of the first tank body 111 and eventually be blocked by the inner tube segment 1121 on the bottom wall of the first tank body 111, unable to enter the interior of the inner tube segment 1121. When the atomizer core assembly 100 is restored to the upright state, the condensate in the first tank body 111 can flow along the outer wall of the inner tube segment 1121 to the atomizer chamber 121, thereby preventing a large amount of condensate from accumulating in the first tank body 111.

[0045] Furthermore, in a specific implementation, as Figure 2 and Figure 5 As shown, the inner sidewall of the first groove body 111 of the atomizing hood 11 extends along the first direction, that is, the cross-sectional area of ​​the inner groove of the first groove body 111 in the first direction remains consistent, which facilitates processing. For example, the first groove body 111 can adopt a hollow cylindrical structure, and the inner groove also adopts a cylindrical groove structure.

[0046] Furthermore, in another specific implementation, as Figure 6As shown, the inner side wall of the first groove body 111 of the atomizing hood 11 is inclined relative to the first direction. In the direction away from the open end 1111 along the first direction, the inner side wall of the first groove body 111 gradually tilts inward, so that the internal groove of the first groove body 111 forms a groove structure similar to a frustum. When the atomizing core assembly 100 is inverted, the first groove body 111 forms a trumpet-like structure with a larger top and a smaller bottom, so as to use the inclined inner side wall of the first groove body 111 to guide the condensate. Among them, the inclination angle of the inner side wall of the first groove body 111 can be set according to the specific size of the first groove body 111 and the use requirements. For example, the angle between the inner side wall of the first groove body 111 and the first direction can be set in the range of 5° to 25°.

[0047] In a further embodiment of the present application, Figure 7 As shown, in the atomizer hood 11, a flow guide structure 1123 is provided on the inner tube section 1121 of the first air pipe 112. The flow guide structure 1123 is located on the outer wall of the inner tube section 1121 at the end away from the outer tube section 1122. The flow guide structure 1123 protrudes toward the outer wall of the inner tube section 1121 and surrounds the inner tube section 1121. When the atomizer core assembly 100 is inverted and then restored to an upright state, condensate attached to the outer wall of the inner tube section 1121 flows along the first direction to the end of the inner tube section 1121 away from the outer tube section 1122. The condensate is guided toward the outer side of the inner tube section 1121 by the flow guide structure 1123, thereby separating the condensate from the outer wall of the inner tube section 1121, thereby further preventing the condensate from entering the interior of the inner tube section 1121. In the direction away from the outer tube section 1122 along the first direction, the flow guide structure 1123 gradually tilts toward the outer side of the inner tube section 1121, as shown in FIG. Figure 7 The example in the embodiment can further improve the diversion effect and prevent the accumulation of condensate at the connection between the diversion structure 1123 and the inner pipe section 1121.

[0048] It should be noted that, in actual applications, the protruding size and inclination angle of the guide structure 1123 can be set according to specific usage requirements. For example, the angle between the inclined surface of the guide structure 1123 and the first direction can be set to 45° to 60°.

[0049] In a further embodiment of the present application, Figure 2 、 Figure 8 and Figure 9As shown, on a plane perpendicular to the first direction, the projection of the inner tube segment 1121 is located inside the projection of the atomizing chamber 121. After the atomizing core assembly 100 is inverted, the inner sidewall of the atomizing chamber 121 is outside the inner tube segment 1121. When the condensed liquid attached to the inner sidewall of the atomizing chamber 121 flows toward the first trough body 111 under the action of gravity, even if the condensed liquid separates from the inner sidewall of the atomizing chamber 121 and drips directly, it will drip into the first groove outside the inner tube segment 1121 and will not fall directly into the inner tube segment 1121.

[0050] It is understood that when the smaller condensate droplets attached to the inner wall of the atomizing chamber 121 gather into larger droplets, they may drip directly due to increased gravity. However, the arrangement in this embodiment can effectively prevent the directly dripping condensate droplets from directly entering the inner tube section 1121.

[0051] Furthermore, if Figure 8 and Figure 9 As shown, the inner tube section 1121 and the atomizing chamber 121 can be coaxially arranged as circular tube structures, and the inner diameter of the inner tube section 1121 is smaller than the inner diameter of the atomizing chamber 121 , so that the projection of the inner tube section 1121 is completely located inside the projection of the atomizing chamber 121 .

[0052] Of course, the shapes of the inner tube section 1121 and the atomization chamber 121 are not limited to the circular tube structure, and other shapes may also be used, such as a square tube structure, which will not be described in detail here.

[0053] In a further embodiment of the present application, Figure 7 and Figure 10As shown, the atomizer core support 12 also has a connecting cavity 122 that is connected to the atomizing cavity 121. The connecting cavity 122 is located at one end of the atomizing cavity 121 close to the first trough body 111, and the end of the connecting cavity 122 facing the atomizing cavity 121 has a guide section 1221, and is connected to the atomizing cavity 121 through the guide section 1221. In the first direction, the end of the connecting cavity 122 away from the atomizing cavity 121 extends into the first trough body 111, and at the same time, the end of the inner tube section 1121 away from the outer tube section 1122 extends into the connecting cavity 122, that is, in the lateral direction, the inner tube section 1121, the connecting cavity 122, and the first trough body 111 all have partially overlapping areas. In which, on a plane perpendicular to the first direction, the projection of the atomizing chamber 121 is located on the inner side of the projection of the connecting chamber 122, that is, in any lateral direction, the transverse inner diameter of the connecting chamber 122 is larger than the inner diameter of the atomizing chamber 121. When the atomizing core assembly 100 is inverted, when the condensate attached to the inner wall of the atomizing chamber 121 flows toward the connecting chamber 122, it can continue to flow along the inner wall of the connecting chamber 122 toward the first trough body 111 under the guiding action of the guide section 1221, so that the condensate is further away from the inner tube section 1121 in the lateral direction, further reducing the possibility of the condensate flowing into the inner tube section 1121.

[0054] Furthermore, if Figure 7 and Figure 10 In the example, the connecting chamber 122 and the atomizing chamber 121 are coaxially arranged circular tube structures, and the inner diameter of the connecting chamber 122 is larger than the inner diameter of the atomizing chamber 121, so that the projection of the atomizing chamber 121 is completely located inside the connecting chamber 122. In the direction approaching the first trough body 111 along the first direction, the guide section 1221 gradually tilts toward the outside of the atomizing chamber 121, so as to guide the condensed liquid attached to the inner wall of the atomizing chamber 121 when the atomizing core assembly 100 is in an inverted state, thereby reducing the possibility of the condensed liquid dripping directly from the inner wall of the atomizing chamber 121.

[0055] It can be understood that the condensate has a certain viscosity. The condensate attached to the inner wall of the atomizing chamber 121 flows downward under the action of gravity. When entering the connecting chamber 122 from the atomizing chamber 121, by reasonably setting the inclination angle of the guide section 1221, the condensate can still adhere to the inner wall after entering the guide section 1221, and then continue to flow along the inner wall of the connecting chamber 122, and avoid dripping downward between the connection between the atomizing chamber 121 and the guide section 1221.

[0056] Furthermore, if Figure 7 and Figure 10In the example, on the atomizer core support 12, a protruding structure 123 is provided on the outer wall of the connecting cavity 122. The protruding structure 123 protrudes toward the outside of the atomizer cavity 121 and abuts against the side wall end face of the first groove body 111 in the first direction to limit the assembly of the first groove body 111 in the first direction.

[0057] The protruding structure 123 may be as follows: Figure 10 The convex structure 123 is a continuous structure that surrounds the circumference. Of course, the convex structure 123 can also be set as a discontinuous structure along the circumference.

[0058] Furthermore, if Figure 11 As shown, the outer wall of the connecting cavity 122 further has a gap area 124, which is recessed toward the inner side of the connecting cavity 122 and extends along a first direction to the end of the outer wall of the connecting cavity 122 away from the atomizing cavity 121. Because the end of the connecting cavity 122 away from the atomizing cavity 121 extends into the first tank body 111, a certain gap space, namely, a liquid storage gap 125, is formed between the gap area 124 on the outer wall of the connecting cavity 122 and the inner wall of the first tank body 111, which can store some condensate.

[0059] In a further embodiment of the present application, Figure 11 and Figure 12 As shown, the atomizer core assembly 100 also includes a liquid absorption structure 14. The liquid absorption structure 14 is arranged in the atomization cavity 121 of the atomizer core support 12. The liquid absorption structure 14 is attached to the outer side wall of the atomizer core body 13 and extends along the circumference of the atomizer core body 13; at least one liquid inlet hole 126 is provided on the side wall of the atomizer core support 12, and the liquid inlet hole 126 is connected to the atomization cavity 121. When the atomizer core assembly 100 is assembled in the atomizer 200, the atomized matrix stored inside the atomizer 200 can flow into the atomization cavity 121 through the liquid inlet hole 126 and be adsorbed on the liquid absorption structure 14, and then an aerosol is generated by the heating and atomization of the atomizer core body 13. By providing the liquid absorption structure 14, the atomized matrix can be in more uniform contact with the atomizer core body 13, while increasing the contact area to improve the atomization efficiency. Among them, the liquid absorption structure 14 can adopt a flexible structure, such as foam, sponge, etc.

[0060] Furthermore, if Figure 11 and Figure 12As shown, a first sealing member 151 is sleeved on the outer tube section 1122 of the first air pipe 112. When the outer tube section 1122 is connected to the mouthpiece 211 of the atomizer 200, the first sealing member 151 seals the connection, preventing the airflow carrying the aerosol from leaking through the gap between the outer tube section 1122 and the mouthpiece 211. Specifically, the first sealing member 151 can be a sealing ring, and a corresponding groove can be provided on the outer sidewall of the outer tube section 1122 to secure the first sealing member 151.

[0061] Furthermore, when the atomizer core assembly 100 is assembled in the corresponding mounting seat 24 in the atomizer 200, a sealing member is provided on the outer wall of the atomizer core support 12, such as Figure 11 and Figure 12 As shown, for example, a second sealing member 152 is provided on the atomizer core support 12 near the first groove body 111, and a third sealing member 153 is provided on the atomizer core support 12 away from the first groove body 111. Both the second sealing member 152 and the third sealing member 153 can be in the form of sealing rings, and grooves can be provided at corresponding positions on the atomizer core support 12 to fix the second sealing member 152 and the third sealing member 153. The second sealing member 152 and the third sealing member 153 seal the gap between the atomizer core support 12 and the mounting base 24 of the atomizer 200.

[0062] In the embodiment of the second aspect of the present application, an atomizer 200 is provided, such as Figure 1 、 Figure 3 as well as Figure 11 and Figure 12 As shown, the atomizer 200 includes a housing 21 and the atomizer core assembly 100 and the power supply device 22 in any embodiment of the first aspect. The atomizer core assembly 100 and the power supply device 22 are both arranged in the housing 21; the housing 21 has a nozzle 211 at one end in the first direction, for example Figure 3 The top of the shell 21 shown in the figure has a suction nozzle 211; the shell 21 has an atomization chamber 212 arranged corresponding to the suction nozzle 211, and the atomization core assembly 100 is arranged in the atomization chamber 212. The first air pipe 112 of the atomization cover 11 of the atomization core assembly 100 is located at one end outside the groove body and is connected to the suction nozzle 211, and the atomization core support 12 is located at the end of the atomization cover 11 away from the suction nozzle 211; the power supply device 22 is electrically connected to the atomization core body 13 to supply power to the atomization core body 13.

[0063] During use, the atomizing matrix in the atomizing bin 212 can enter the atomizing cavity 121 in the atomizing core support 12, and the atomizing core body 13 is energized to heat and atomize the atomizing matrix to generate an aerosol; when the user draws in air through the mouthpiece 211, the aerosol in the atomizing cavity 121 flows along with the suction airflow to the outlet end of the mouthpiece 211 for the user to inhale.

[0064] During use, a certain amount of condensate may form inside the atomizer core assembly 100 and adhere to the inner wall surface of the atomizer core assembly 100. When the atomizer 200 is inverted, the condensate adhered to the inner wall of the atomizer chamber 121 flows into the first tank body 111 under the action of gravity, and is blocked at the bottom wall of the first tank body 111 by the portion of the first air pipe 112 extending into the first tank body 111, preventing it from directly entering the first air pipe 112. Therefore, it is difficult for the condensate to flow through the first air pipe 112 to the suction nozzle 211, which can effectively prevent condensate leakage from the suction nozzle 211.

[0065] It should be noted that the suction nozzle 211 and the housing 21 can be an integrated structure or independent split structures, which are assembled into one by connection.

[0066] In a further embodiment of the present application, Figure 3 In the example, the interior of the mouthpiece 211 has a second air pipe 213, which extends along the first direction and passes through the mouthpiece 211. Accordingly, the first air pipe 112 of the atomizer core assembly 100 is sealedly connected to the second air pipe 213 at one end facing the mouthpiece 211 to form an air flow channel connected to the mouthpiece 211.

[0067] Specifically, if Figure 3 In the example, the first air pipe 112 may be arranged to extend from one end outside the first tank 111 into the second air pipe 213, as shown in FIG. Figure 11 and Figure 12 In the example shown in FIG, a first sealing member 151 can be provided on the outer wall of the portion of the air pipe extending into the second air pipe 213 to form a sealed connection between the first air pipe 112 and the second air pipe 213. The second air pipe 213 can be axially limited by the first groove 111, or a corresponding step structure can be provided on the inner wall of the second air pipe 213 so that the first air pipe 112 abuts against the step structure and is limited.

[0068] Of course, the connection method between the first air pipe 112 and the second air pipe 213 is not limited to Figure 3 In the example, other connection methods can also be used, for example, the second air pipe 213 is set to extend into the first air pipe 112, or the end face of the first air pipe 112 is abutted against the end face of the second air pipe 213, and connected through a corresponding flange structure, which will not be repeated here.

[0069] In a further embodiment of the present application, Figure 3As shown, the shell 21 has a liquid storage tank 214, which is separated from the atomization tank 212 by a partition. A connecting port 215 is provided on the partition, and a connecting valve 216 is provided at the connecting port 215 to open or close the connecting port 215 through the connecting valve 216. When the connecting port 215 is open, the atomization matrix in the liquid storage tank 214 can enter the atomization tank 212 to be heated and atomized by the atomization core body 13 to generate aerosol.

[0070] Specifically, if Figure 3 In the example, a corresponding push rod mechanism 23 can be provided on the housing 21 at a position opposite to the communication port 215 (e.g., the bottom of the housing 21), and the other end of the push rod mechanism 23 is connected to the communication valve 216. The push rod mechanism 23 can be pressed from the outside of the housing 21 to drive the communication valve 216 to move, thereby opening the communication port 215; the push rod mechanism 23 can move in the opposite direction to drive the communication valve 216 to close the communication port 215. Among them, a corresponding elastic reset structure can also be provided on the push rod mechanism 23. When the external force pressing the push rod mechanism 23 is removed, the push rod mechanism 23 can reset itself and close the communication port 215. By providing an independent liquid storage tank 214 and atomization tank 212, it is possible to prevent leakage caused by excessive atomization matrix in the atomization tank 212, and the corresponding rehydration operation can be performed according to the needs of use, which is convenient to use.

[0071] In practical applications, such as Figure 3 In the example, a corresponding mounting seat 24 can also be provided in the atomizing chamber 212, and the atomizing core assembly 100 can be assembled inside the mounting seat 24 to install and fix the atomizing core assembly 100. A sealing member is provided on the outer wall of the atomizing core support 12, for example Figure 11 and Figure 12 The first sealing member 151 and the second sealing member 152 are shown in the figure to seal the gap between the atomizer core support 12 and the mounting seat 24.

[0072] In addition, according to actual needs, an independent electrical appliance compartment can be provided in the housing 21, such as Figure 3 In the left area of ​​the housing 21 shown in the figure, the power supply device 22 and the associated electrical components are arranged in the electrical compartment, and are introduced into the atomization compartment 212 through a lead or pin structure to be electrically connected to the atomization core body 13, so as to provide insulation and isolation for the power supply device 22 and the corresponding electrical components.

[0073] In addition, the atomizer 200 in this embodiment also has all the beneficial effects of the atomizer core assembly 100 in any of the above embodiments, which will not be described in detail here.

[0074] The following is a specific embodiment of the atomizer of the present application.

[0075] Please refer to Figures 1 to 12The atomizer 200 of the present application includes a housing 21 , a power supply device 22 and an atomizing core assembly 100 .

[0076] like Figure 3 In the example, the up-down direction of the housing 21 is the first direction. The top of the housing 21 has an opening, and the opening is connected to the nozzle 211. The housing 21 is separated by a partition into an atomizing chamber 212, a liquid storage chamber 214, and an electrical chamber. The atomizing chamber 212 is arranged corresponding to the nozzle 211. The interior of the nozzle 211 has a second air pipe 213 that runs through it along the first direction, and one end of the second air pipe 213 extends into the atomizing chamber 212. The atomizing core assembly 100 is arranged in the atomizing chamber 212, the atomizing core support 12 is installed in the mounting seat 24 in the atomizing chamber 212, and the atomizing cover 11 is located at one end near the nozzle 211. The electrical compartment is located on one side of the atomization compartment 212, and the power supply device 22 and auxiliary electrical components are arranged in the electrical compartment; the liquid storage compartment 214 is located below the atomization compartment 212, and a connecting port 215 is provided on the partition between the liquid storage compartment 214 and the atomization compartment 212, and a connecting valve 216 is provided at the connecting port 215. A push rod mechanism 23 is provided at the bottom of the shell 21, and one end of the push rod mechanism 23 extends into the liquid storage compartment 214 and is connected to the connecting valve 216. The connecting valve 216 can be driven to move along the first direction by pressing the push rod mechanism 23 to open or close the connecting port 215.

[0077] like Figure 1 、 Figure 5 ,as well as Figure 11 and Figure 12 As shown, the atomizer core assembly 100 includes an atomizer cover 11, an atomizer core support 12, an atomizer core body 13, and a liquid absorption structure 14. The atomizer cover 11 includes a first groove 111 and a first air pipe 112 extending through the first groove 111. The first groove 111 and the first air pipe 112 both extend along a first direction and are an integrated structure. The open end 1111 of the first groove 111 faces the atomizer core support 12. The first air pipe 112 of the atomizer cover 11 includes an inner pipe section 1121 and an outer pipe section 1122 arranged sequentially in the first direction. The inner tube section 1121 is passed through the first trough body 111, and in the first direction, the length of the inner tube section 1121 is less than the length of the side wall of the first trough body 111; the outer tube section 1122 is located on the end of the first trough body 111 away from the open end 1111, and the end of the outer tube section 1122 away from the first trough body 111 extends into the second air pipe 213. A first sealing member 151 is sleeved on the outer tube section 1122. The first sealing member 151 is in the form of a sealing ring to seal the gap between the outer wall of the outer tube section 1122 and the inner wall of the second air pipe 213. A corresponding step structure is provided on the inner wall of the second air pipe 213, and the end of the outer tube section 1122 extending into the second air pipe 213 abuts against the step structure. Figure 2 and Figure 5As shown, the inner side wall of the first groove body 111 of the atomizing cover 11 extends along the first direction. Specifically, the first groove body 111 adopts a hollow cylindrical structure, and the internal groove also adopts a cylindrical groove structure.

[0078] like Figure 2 、 Figure 8 and Figure 9 As shown, the interior of the atomizer core support 12 is through along the first direction, and includes an atomizing chamber 121 and a connecting chamber 122 connected in the first direction, the connecting chamber 122 is close to the atomizing cover 11, and the atomizing chamber 121 is away from the atomizing cover 11. A plurality of liquid inlet holes 126 are circumferentially spaced apart at positions corresponding to the atomizing chamber 121 on the side wall of the atomizer core support 12, and the atomizer core body 13 is arranged at positions corresponding to the liquid inlet holes 126 in the atomizing chamber 121; the atomizing chamber 121 is filled with a liquid absorbing structure 14, and the liquid absorbing structure 14 is circumferentially covered on the outer wall of the atomizer core body 13. Figure 7 and Figure 10 As shown, the connecting chamber 122 has a guide section 1221 at one end facing the atomizing chamber 121, and is communicated with the atomizing chamber 121 through the guide section 1221. In the first direction, the connecting chamber 122 extends into the first trough body 111 away from the end of the atomizing chamber 121, and at the same time, the inner tube section 1121 extends into the connecting chamber 122 away from the end of the outer tube section 1122. Wherein, the inner tube section 1121, the atomizing chamber 121 and the connecting chamber 122 are all coaxially arranged circular tube structures, and the inner diameter of the inner tube section 1121 is smaller than the inner diameter of the atomizing chamber 121, and the inner diameter of the atomizing chamber 121 is smaller than the inner diameter of the connecting chamber 122, so that on a plane perpendicular to the first direction, the projection of the inner tube section 1121 is completely located on the inner side of the projection of the atomizing chamber 121, and the projection of the atomizing chamber 121 is completely located on the inner side of the projection of the connecting chamber 122.

[0079] like Figure 7 and Figure 10 In the example, on the atomizer core support 12, a protruding structure 123 is provided on the outer wall of the connecting cavity 122. The protruding structure 123 protrudes toward the outside of the atomizer cavity 121 and surrounds the atomizer core support 12 along the circumference. In the first direction, the protruding structure 123 abuts against the end surface of the side wall of the first groove body 111.

[0080] like Figure 11 and Figure 12As shown, in the first direction, two raised structures 123 are spaced apart on the outer wall of the connecting cavity 122, and a second sealing member 152 is provided in the gap between the two raised structures 123. The second sealing member 152 is in the form of a sealing ring. An annular groove is provided on the outer wall of the atomizer core support 12 at a position away from the first trough body 111. A third sealing member 153 is provided in the annular groove. The third sealing member 153 is in the form of a sealing ring. The atomizer core support 12 is installed in the mounting base 24 of the atomizer bin 212. The area on the mounting base 24 corresponding to the liquid inlet hole 126 of the atomizer chamber 121 has a hollow structure. The position on the inner side wall of the mounting base 24 corresponding to the connecting cavity 122 abuts against the outer wall of the raised structure 123 and is sealed by the second sealing member 152. The position on the inner side wall of the mounting base 24 corresponding to the area below the liquid inlet hole 126 abuts against the outer wall of the atomizer core support 12 and is sealed by the third sealing member 153.

[0081] When using, such as Figure 3 In the example shown in FIG, the atomizer 200 can be inverted, and the connecting port 215 between the atomizing chamber 212 and the liquid storage chamber 214 can be opened by pressing the push rod mechanism 23, so that the atomized matrix in the liquid storage chamber 214 enters the atomizing chamber 212 through the connecting port 215, flows into the atomizing chamber 121 through the liquid inlet hole 126 on the atomizing core support 12, and is adsorbed on the liquid absorbing structure 14. During the atomization operation, the power supply device 22 supplies power to the atomizing core body 13, and the atomizing core body 13 heats the liquid absorbing structure 14, so that the atomized matrix adsorbed on the liquid absorbing structure 14 is heated and atomized to produce an aerosol; when the user draws in through the mouthpiece 211, a negative pressure state is formed in the atomizing chamber 121, and the aerosol flows along the airflow from the first air pipe 112 and the second air pipe 213 to the end of the mouthpiece 211 for the user to inhale.

[0082] Among them, when the atomizer 200 is in an inverted state, the open end 1111 of the first trough body 111 faces upward, and the condensate attached to the inner wall of the atomizing chamber 121 and the inner wall of the connecting chamber 122 flows downward under the action of gravity and flows into the first trough body 111. The condensate dripping on the inner wall of the atomizing chamber 121 also directly enters the first trough body 111. When the condensate flows to the bottom wall of the first trough body 111, it is blocked in the horizontal direction by the inner tube section 1121 of the first air pipe 112 and is difficult to flow into the first air pipe 112. When the atomizer 200 returns to the upright state, the open end 1111 of the first trough body 111 faces downward, and the condensate in the first trough body 111 can flow downward along the outer wall of the inner tube section 1121 and flow back into the atomizing chamber 121. Through the above arrangement, it is possible to effectively prevent the condensate from flowing into the first air pipe 112 and leaking out through the suction nozzle 211.

Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
