The present application is further described in detail below in conjunction with the drawings and specific embodiments.

[0034] One aspect of the present application provides an aerosol generating device. Figures 1 to 8 , comprising a power supply assembly 200 and an atomizer 100 provided by any embodiment of the present application. The power supply assembly 200 is electrically connected to the atomizer 100.

[0035] The power supply assembly 200 is electrically connected to the atomizer 100 , for example, is electrically connected to the atomizer core 20 of the atomizer 100 . Exemplarily, the power supply assembly 200 is electrically connected to the atomizer core 20 via the conductive member 40 of the atomizer 100 .

[0036] In this embodiment, the atomizer 100 exists independently of the power supply assembly 200, and the atomizer 100 is detachably connected to the power supply assembly 200. However, in some embodiments, the power supply assembly 200 and the atomizer 100 are packaged in the same housing 50 and are relatively non-detachable.

[0037] The power supply assembly 200 is mainly used to supply power to the atomizer 100 and control the opening or closing of the entire aerosol generating device, and the atomizer 100 is mainly used to contain an aerosol generating substrate and heat and atomize the aerosol generating substrate after power is turned on. The aerosol generating substrate includes, but is not limited to, materials used for medical treatment, health preservation, health, beauty, and the like.

[0038] In some embodiments, the atomizer 100 and the power supply assembly 200 can be mechanically and electrically connected together along the axial direction. Furthermore, the atomizer 100 and the power supply assembly 200 can be connected together in a detachable manner such as a magnetic connection, a threaded connection, a snap connection, etc. The atomizer 100 and the power supply assembly 200 can be replaced or upgraded separately, reducing the replacement cost and saving user expenses. Of course, in other embodiments, the atomizer 100 and the power supply assembly 200 can also be connected together in a non-detachable manner.

[0039] In addition, the atomizer 100 and / or the power supply assembly 200 are not limited to being cylindrical, and may also be in other shapes such as an elliptical column, a square box, or a polygonal column. For example, in this embodiment, the cross section of the lower end of the atomizer 100 is approximately elliptical, and the cross section of the upper part of the atomizer 100 is approximately flat.

[0040] It should be noted that the specific type of the aerosol generating device provided in the embodiments of the present application is not limited. By way of example, the aerosol generating device may be a medical atomization device, an air humidifier, or an atomization device such as an electronic cigarette.

[0041] Another aspect of the present application provides an atomizer, see Figures 2 to 8 , the atomizer 100 includes an atomizer core 20 and an atomizer seat assembly 10. The atomizer seat assembly 10 includes an atomizer base 12 and at least two mounting seats 13 arranged on the atomizer base 12. At least part of the area of ​​the at least two mounting seats 13 is arranged at intervals, and at least part of the atomization chamber 10a is defined between the at least two mounting seats 13. The mounting seat 13 is provided with a liquid inlet channel 13a. The atomizer core 20 is arranged on the mounting seat 13 and is connected to the liquid inlet channel 13a. The atomization surface of the atomizer core 20 faces the atomization chamber 10a.

[0042] Here, the atomizer core 20 is connected to the liquid inlet channel 13a, which means that the aerosol generating substrate in the liquid inlet channel 13a can flow to the atomizing surface of the atomizer core 20, and the atomizing surface heats and atomizes the aerosol generating substrate to generate aerosol.

[0043] Exemplarily, the side wall of the mounting seat 13 facing the atomizing chamber 10a is provided with an opening 13b communicating with the liquid inlet channel 13a. The atomizing core 20 is arranged at the opening 13b, and the atomizing surface of the atomizing core 20 faces the atomizing chamber 10a.

[0044] The atomizer seat assembly 10 includes at least two mounting seats 13 , which means that the number of the mounting seats 13 can be two or more.

[0045] At least partial areas of at least two mounting seats 13 are spaced apart, which means that the mounting seats 13 may not contact each other so that at least a portion of the atomization chamber 10a is defined between the mounting seats 13, or partial areas of the mounting seats 13 may contact each other and partial areas may not contact each other so that at least a portion of the atomization chamber 10a is defined between the mounting seats 13.

[0046] Here, at least part of the atomization chamber 10 a is defined between at least two mounting seats 13 , which means that the entire atomization chamber 10 a is defined between the mounting seats 13 , or part of the atomization chamber 10 a is defined between the mounting seats 13 .

[0047] Exemplarily, the nebulizer 100 further includes a liquid storage chamber 100a, and the liquid storage chamber 100a is used to store an aerosol-generating substrate.

[0048] Exemplarily, the atomizer 100 further includes an air outlet channel 51 a, and the air outlet channel 51 a is used to discharge the aerosol in the atomization chamber 10 a.

[0049] It should be noted that the atomizing surface of the atomizing core 20 faces the atomizing chamber 10a, and the atomizing surface of the atomizing core 20 may be arranged parallel to the center line of the air outlet channel 51a, or may be arranged inclined relative to the center line of the air outlet channel 51a.

[0050] The mounting seat 13 is provided with a liquid inlet channel 13a, and a side wall of the mounting seat 13 facing the atomizing chamber 10a is provided with an opening 13b communicating with the liquid inlet channel 13a, and the atomizing core 20 is arranged at the opening 13b.

[0051] Here, the liquid inlet channel 13a is connected to the liquid storage chamber 100a, and the liquid inlet channel 13a is used to guide the aerosol generating matrix to the atomizing core 20 at the opening 13b, that is, the liquid absorption surface of the atomizing core 20 is used to absorb the aerosol generating matrix, and the atomizing surface heats and atomizes the aerosol generating matrix to generate an aerosol.

[0052] Understandably, see Figures 4 to 7 The side wall of the mounting seat 13 facing the atomizing chamber 10a is provided with an opening 13b, and the atomizing core 20 is arranged at the opening 13b, that is, the atomizing core 20 is arranged laterally, so that the atomizing core 20 and the atomizing chamber 10a can be directly exposed to the air outlet channel 51a of the atomizer 100, that is, directly connected with the air outlet channel 51a, and the generated aerosol is mixed with the air entering the atomizing chamber 10a and is directly taken out, and the aerosol generated by atomization does not need to be bent to finally reach the user, thereby reducing the loss of aerosol and improving the explosiveness of taste.

[0053] The atomizing core 20 can block the flow of the aerosol-generating substrate in the liquid inlet channel 13 a , that is, the aerosol-generating substrate will not flow directly into the liquid storage chamber 100 a .

[0054] Here, the number of the openings 13 b is the same as the number of the atomizer cores 20 , that is, the openings 13 b correspond to the atomizer cores 20 one by one.

[0055] It should be noted that the number of the liquid inlet channels 13 a provided on each mounting seat 13 may be one or more, and the number of the openings 13 b provided on each liquid inlet channel 13 a may also be one or more, which is not limited here.

[0056] The multiple mentioned in the embodiments of the present application refers to a number of two or more.

[0057] Here, by providing a plurality of atomizer cores 20, it is beneficial to improve the atomization efficiency of the atomizer 100. In this way, the power borne by a single atomizer core 20 can be reduced, the redundancy can be increased, the service life of the atomizer core 20 can be extended, and the reliability can be improved.

[0058] It should be noted that the specific structure of the atomizer core 20 is not limited here.

[0059] Exemplarily, the atomizing core 20 includes a substrate and a heating element, wherein the substrate has an atomizing surface and a liquid absorbing surface, and the heating element is disposed on the atomizing surface. The heating element is used to heat the atomized aerosol to generate the substrate.

[0060] It should be noted that the material of the substrate is not limited here. For example, in one embodiment, the substrate is a conductive material, such as a metal or alloy such as iron-chromium-aluminum, nickel-chromium or stainless steel. In other embodiments, the substrate may also be an electrically insulating material, including but not limited to ceramics, glass, polyimide, etc. The following embodiments are all illustrated by taking the substrate as ceramic as an example.

[0061] It should be noted that the specific contour shape of the substrate is not limited here, and the contour shape of the substrate includes but is not limited to any one of a polyhedron, a pyramid, a prism, a frustum or a cylinder.

[0062] For example, the outline shape of the base body may be a three-dimensional structure surrounded by a number of polygons.

[0063] The structure of the heating element can be a continuous film, a porous mesh or a strip. The material, shape and size of the heating element can be set as required.

[0064] It should be noted that the specific structure of the heating element is not limited here, and the heating element includes but is not limited to a heating sheet, a heating film, a heating net, etc. The following embodiments are all illustrated by taking the heating element as a heating film as an example.

[0065] It should be noted that, in this embodiment, the aerosol generating matrix is ​​liquid. The liquid aerosol generating matrix can be transferred from the liquid absorption surface of the matrix to the heating element on the atomization surface through the capillary force of the matrix. The heating element generates heat to heat and atomize the aerosol generating matrix.

[0066] In the related art, the atomizing core of the aerosol generating device is generally a cotton core heating element or a ceramic core. However, the current ceramic core atomizer, especially the small volume (about 2ml) product, is generally atomized downward (that is, the atomizing surface faces the bottom of the atomizer) due to the limitation of volume space. In the above two mainstream methods, the aerosol generated by atomization needs to be bent to finally reach the user, so the aerosol loss is large, which makes it difficult to improve the atomization efficiency and taste. The present application adopts the method of lateral atomization (that is, the atomizing surface faces the side), which can reduce the loss of aerosol, and adopts multiple atomizing cores, which can improve the atomization efficiency and the explosiveness of the taste, but there are problems of complex structure and inconvenient assembly.

[0067] The atomizer provided in the embodiment of the present application includes an atomizer core 20 and an atomizer seat assembly 10. The atomizer seat assembly 10 includes an atomizer base 12 and at least two mounting seats 13 arranged on the atomizer base 12. On the one hand, at least part of the atomization chamber 10a is defined between at least two mounting seats 13, and the atomizer core 20 is arranged on the mounting seat 13, which is conducive to the lateral arrangement of the atomizer core 20, so that the explosive force of the taste can be improved. On the other hand, by setting a plurality of mounting seats 13, that is, correspondingly setting a plurality of atomizer cores 20, it is conducive to improving the atomization efficiency and further improving the explosive force of the taste. In addition, the power borne by a single atomizer core 20 can be reduced, the redundancy can be increased, the service life of the atomizer core 20 can be extended, and the reliability can be improved. On the other hand, by connecting a plurality of mounting seats 13 to the atomizer base 12 respectively, it is conducive to assembling the atomizer core 20, and the structure is simple and easy to assemble.

[0068] At least part of the atomizing chamber 10a is defined between at least two mounting seats 13, and the side wall of the mounting seat 13 facing the atomizing chamber 10a is provided with an opening 13b connected with the liquid inlet channel 13a, and the atomizing core 20 is arranged at the opening 13b, that is, the atomizing core 20 is arranged laterally, so that the explosiveness of the taste can be improved.

[0069] It should be noted that the connection method between the mounting base 13 and the atomizing base 12 is not limited here. For example, it can be a magnetic connection, a snap connection, a fastening connection or a plug connection. Among them, the fastening connection includes but is not limited to a screw connection, a bolt connection or a rivet connection, etc.

[0070] Exemplarily, there are two mounting seats 13, which are arranged opposite to the atomizing base 12. The atomizing base 12 is provided with a first clamping portion 12b, and the mounting seat 13 is provided with a second clamping portion 13f, and the first clamping portion 12b is matched and connected with the second clamping portion 13f.

[0071] Here, the atomizer base 12 and the mounting base 13 are engaged with each other by respectively providing a first engaging portion 12b and a second engaging portion 13f to buckle and clamp the mounting base 13, thereby realizing that the two mounting bases 13 are relatively connected to the atomizer base 12. The connection structure is simple, reliable, and easy to assemble.

[0072] Specifically, see Figures 4 to 8 , the number of mounting seats 13 is two, and the two mounting seats 13 are arranged opposite to the atomizing base 12 along the first direction. The atomizing base 12 is provided with a first clamping portion 12b on both sides along the first direction, and a connecting member 12a is provided on both sides along the second direction, and each connecting member 12a is provided with two third clamping portions 12c arranged along the first direction. The mounting seat 13 is provided with a second clamping portion 13f on one side along the first direction, and a fourth clamping portion 13n is provided on both sides along the second direction. The first clamping portion 12b is clamped and matched with the second clamping portion 13f, and the third clamping portion 12c is clamped and matched with the fourth clamping portion 13n, so that the mounting seat 13 is connected to the atomizing base 12. Wherein, the first direction intersects with the second direction.

[0073] Here, one of the first clamping portion 12b and the second clamping portion 13f is a buckle, and the other is a clamping groove.

[0074] Likewise, one of the third clamping portion 12c and the fourth clamping portion 13n is a buckle, and the other is a clamping slot.

[0075] The intersection of the first direction and the second direction means that the first direction and the second direction are not parallel. Figure 6 , the first direction is perpendicular to the second direction.

[0076] In this embodiment, a first clamping portion 12b and a third clamping portion 12c are provided on the atomizer base 12, and a second clamping portion 13f and a fourth clamping portion 13n are provided on the mounting seat 13. The first clamping portion 12b is engaged with the second clamping portion 13f, and the third clamping portion 12c is engaged with the fourth clamping portion 13n, so that the mounting seat 13 is snapped and clamped, thereby realizing that the two mounting seats 13 are relatively connected to the atomizer base 12 along the first direction. The connection structure is simple, reliable, and easy to assemble.

[0077] In some embodiments, see Figures 3 to 5 The number of the atomizer cores 20 is two, and the two atomizer cores 20 are arranged in parallel.

[0078] Here, the two atomizer cores 20 are arranged in parallel means that the planes where the atomizing surfaces of the two atomizer cores 20 are located are arranged in parallel, that is, the two atomizer cores 20 are arranged face to face.

[0079] It should be noted that the two atomizer cores 20 being arranged in parallel means that the two atomizer cores 20 are completely parallel or approximately parallel.

[0080] In this embodiment, the atomizer core 20 is arranged laterally so that the aerosol generated by atomization does not need to be bent to finally reach the user, thereby reducing aerosol loss and improving the explosiveness of the mouthfeel. At the same time, the two atomizer cores 20 are arranged in parallel, which is conducive to improving the uniformity of aerosol generation, thereby improving the consistency of suction.

[0081] In the related art, the electrical connection of the atomizer core 20 has the problem of complex connection structure.

[0082] In some embodiments, see Figures 4 to 6 The atomizer 100 includes a conductive member 40 , which is disposed in the atomizing chamber 10 a and is in contact with electrodes of at least two atomizing cores 20 at the same time.

[0083] Here, the specific structure of the conductive member 40 is not limited. Exemplarily, the conductive member 40 is, for example, a pin.

[0084] Specifically, see Figure 4 A partial area of ​​the conductive member 40 forms a flange 40 a, which contacts the electrode of the atomizer core 20 through the flange 40 a, or the conductive member 40 directly contacts the electrode of the atomizer core 20 .

[0085] The contact between the conductive member 40 and the electrode of the atomizer core 20 means that the contact state can be a squeeze state or a non-squeeze state.

[0086] Exemplarily, the conductive member 40 extends from the bottom of the atomizing base 12 and into the atomizing chamber 10a.

[0087] In this embodiment, by setting the conductive member 40 to contact the electrodes of at least two atomizer cores 20 at the same time, that is, the atomizer cores 20 that are in contact with the conductive member 40 at the same time are arranged in parallel, on the one hand, the number of conductive members 40 can be reduced, the cost can be reduced, the assembly efficiency can be improved, and the occupied space can be reduced. On the other hand, the voltage distribution of the atomizer cores 20 can be equal, the power borne by a single atomizer core 20 can be reduced, the redundancy can be increased, the service life of the atomizer core 20 can be extended, and the reliability can be improved. On the other hand, it is only necessary to connect the mounting seat 13 to the atomizer base 12, and the atomizer base 12 and the mounting seat 13 are closely matched, so that the conductive member 40 contacts the electrode of the atomizer core 20 on the mounting seat 13 to achieve electrical connection, thereby improving the stability of the electrical connection between the electrode of the atomizer core 20 and the conductive member 40, and the structure is simple and easy to assemble.

[0088] In some other embodiments, each conductive member 40 is in contact with only one electrode of the atomizer core 20 .

[0089] Here, each conductive member 40 is in contact with only one electrode of the atomizer core 20 , which is helpful to improve the reliability of the electrical connection between the conductive member 40 and the atomizer core 20 .

[0090] In some embodiments, see Figure 3 and Figure 4 The atomizer 100 includes an air outlet channel 51a connected to the atomizing chamber 10a, the air outlet channel 51a is used to discharge the aerosol in the atomizing chamber 10a, and the atomizing surface of the atomizing core 20 is parallel to the center line of the air outlet channel 51a.

[0091] The atomizing surface of the atomizing core 20 is parallel to the center line of the air outlet channel 51 a means that the atomizing surface is substantially parallel to or completely parallel to the center line of the air outlet channel 51 a .

[0092] The atomizer 100 includes an air outlet pipe 51 having an air outlet passage 51 a , and one end of the air outlet pipe 51 extends into the atomizing chamber 10 a so that the air outlet passage 51 a is communicated with the atomizing chamber 10 a .

[0093] The air outlet pipe 51 is disposed at the top of the atomizer seat assembly 10 so that the air outlet channel 51a is connected to the atomizer chamber 10a. In this way, the aerosol generated in the atomizer chamber 10a is directly discharged through the air outlet channel 51a for use by the user.

[0094] In this embodiment, the atomizing surface of the atomizer core 20 is arranged parallel to the center line of the air outlet channel 51a, so that the atomizer core 20 and the atomization chamber 10a can be directly exposed to the air outlet channel 51a, that is, directly connected to the air outlet channel 51a, and the generated aerosol is mixed with the air entering the atomization chamber 10a and is directly taken out, which can reduce the aerosol loss and improve the taste explosiveness.

[0095] In some embodiments, see Figures 4 to 8 The atomizer seat assembly 10 is provided with a ventilation channel 10b, the air inlet of the ventilation channel 10b is connected to the external atmosphere, and the air outlet 10c of the ventilation channel 10b is connected to the liquid inlet channel 13a; the air outlet 10c is lower than the liquid inlet 13d of the liquid inlet channel 13a.

[0096] It should be noted that the liquid inlet channel 13a can be formed on the mounting seat 13, that is, the liquid inlet port 13d of the liquid inlet channel 13a can pass through the top wall or side wall of the mounting seat 13, or the liquid inlet channel 13a can be defined between the mounting seat 13 and the housing 50.

[0097] In some other embodiments, the ventilation channel 10b may also be disposed on the bottom wall of the liquid inlet channel 13a.

[0098] The aerosol-generating substrate in the liquid storage chamber 100a enters the liquid inlet channel 13a through the liquid inlet port 13d. The atomizer core 20 is generally disposed at the bottom of the liquid inlet channel 13a, which is conducive to the aerosol-generating substrate in the liquid inlet channel 13a flowing to the atomizer core 20 as evenly as possible, thereby improving the utilization rate of the aerosol-generating substrate.

[0099] The aerosol-generating matrix in the liquid storage chamber 100a is guided to the atomizing core 20 through the liquid inlet channel 13a for heating and atomization to generate an aerosol. After the aerosol-generating matrix in the liquid storage chamber 100a is consumed, the outside air enters the liquid inlet channel 13a through the air outlet 10c of the ventilation channel 10b, and then enters the liquid storage chamber 100a to balance the pressure in the liquid storage chamber 100a.

[0100] Here, the gas outlet 10c penetrates the side wall of the mounting seat 13, and the gas outlet 10c is lower than the liquid inlet 13d.

[0101] In this embodiment, by setting the air outlet 10c of the ventilation channel 10b to be lower than the liquid inlet 13d, it is helpful to reduce the height difference between the air outlet 10c of the ventilation channel 10b and the atomizer core 20, thereby improving the leakage situation.

[0102] Of course, in other embodiments, the liquid inlet 13d of the liquid inlet channel 13a passes through the top wall of the mounting seat 13, and the air outlet 10c of the ventilation channel 10b also passes through the top wall of the mounting seat 13 and extends to the liquid inlet 13d, that is, the air outlet 10c is flush with the liquid inlet 13d.

[0103] In some embodiments, see Figure 3 and Figure 7 , the air outlet 10c is not higher than the highest point of the atomizer core 20.

[0104] That is to say, the air outlet 10 c is lower than the highest point of the atomizer core 20 , or is flush with the highest point of the atomizer core 20 .

[0105] By setting the air outlet 10c not higher than the highest point of the atomizer core 20, the leakage situation can be further improved.

[0106] In some embodiments, the air outlet 10 c is set to be no lower than the lowest point of the atomizer core 20 .

[0107] It can be understood that the smaller the height difference between the air outlet 10c and the lowest point of the atomizer core 20 is, the less likely it is to leak liquid.

[0108] In this embodiment, by setting the air outlet 10c of the ventilation channel 10b to be not lower than the lowest point of the atomizer core 20, that is, the air outlet 10c is set between the liquid inlet 13d and the lowest point of the atomizer core 20, it is beneficial to reduce the height difference between the air outlet 10c of the ventilation channel 10b and the atomizer core 20, thereby improving the leakage situation.

[0109] In some embodiments, see Figure 4 The mounting seat 13 is provided with a ventilation groove 13c, and the atomizer seat assembly 10 includes a first sealing member 14, which is sleeved on the outer side wall of the mounting seat 13 and defines at least a portion of the ventilation channel 10b between the first sealing member 14 and the ventilation groove 13c.

[0110] Here, one end of the ventilation groove 13c is connected to the external atmosphere, and the other end is connected to the liquid inlet channel 13a. The first sealing member 14 is sleeved on the outer wall of the mounting seat 13 so that at least part of the ventilation channel 10b is defined between the groove wall of the ventilation groove 13c and the first sealing member 14.

[0111] At least a portion of the ventilation channel 10b is defined between the first sealing member 14 and the ventilation groove 13c. This means that the entire ventilation channel 10b may be defined between the first sealing member 14 and the ventilation groove 13c, or that a portion of the ventilation channel 10b is defined between the first sealing member 14 and the ventilation groove 13c.

[0112] The first sealing member 14 includes a sealing top wall and a sealing side wall. The sealing top wall is disposed on the top wall of the mounting seat 13 , and the sealing side wall is disposed on the side wall of the mounting seat 13 .

[0113] The material of the first sealing member 14 is not limited, for example, silicone, rubber, etc.

[0114] In this embodiment, by providing the first sealing member 14, the ventilation channel 10b is defined between the first sealing member 14 and the ventilation groove 13c, and the liquid inlet channel 13a can be sealed to prevent liquid leakage.

[0115] In some embodiments, see Figures 4 to 8The side wall of the mounting seat 13 is provided with a ventilation hole 13e connected to the liquid inlet channel 13a, and the ventilation groove 13c extends to the hole wall of the ventilation hole 13e. The flow cross-sectional area of ​​the ventilation groove 13c is smaller than the flow cross-sectional area of ​​the ventilation hole 13e.

[0116] It should be noted that the flow section refers to the cross section orthogonal to all streamlines of the elementary flow or the total flow, that is, the plane perpendicular to the flow velocity cluster, such as the air flow or liquid flow. When the streamline clusters are not parallel to each other, the flow section is a curved surface; when the streamline clusters are parallel straight lines, the flow section is a plane.

[0117] The ventilation groove 13c extends to the hole wall of the ventilation hole 13e, that is, part of the ventilation groove 13c is formed on the hole wall of the ventilation hole 13e, or the hole wall of the ventilation hole 13e is partially recessed to form the ventilation groove 13c.

[0118] The fact that the flow cross-sectional area of ​​the ventilation groove 13c is smaller than that of the ventilation hole 13e means that, in a section perpendicular to the depth direction of the ventilation hole 13e, the cross-sectional area of ​​the ventilation groove 13c is smaller than that of the ventilation hole 13e.

[0119] In the related art, the air outlet of the ventilation channel is usually small, and the bubbles generated after ventilation will be retained near the air outlet and cannot be discharged, resulting in the accumulation of ventilation bubbles and blocking the air outlet.

[0120] The embodiment of the present application is to provide a ventilation hole 13e connected to the liquid inlet channel 13a through the side wall of the mounting seat 13, and the flow cross-sectional area of ​​the ventilation groove 13c is smaller than the flow cross-sectional area of ​​the ventilation hole 13e, that is, the flow cross-sectional area of ​​the air outlet 10c is smaller than the flow cross-sectional area of ​​the ventilation hole 13e. In this way, the bubbles generated at the air outlet 10c after ventilation will be discharged through the ventilation hole 13e with a larger cross-sectional area, thereby improving the problem of ventilation bubbles gathering and blocking the air outlet 10c.

[0121] In some embodiments, see Figure 4 The first sealing member 14 is formed with a protrusion 14a, which is accommodated in the ventilation hole 13e, and the length of the protrusion 14a is smaller than the depth of the ventilation hole 13e.

[0122] The protrusion 14a is accommodated in the ventilation hole 13e, so that the side wall of the protrusion 14a is sealed and matched with the hole wall of the ventilation hole 13e, thereby realizing the sealing of the ventilation hole 13e by the protrusion 14a.

[0123] The length of the protrusion 14a is smaller than the depth of the ventilation hole 13e, which means that the protrusion 14a does not exceed the ventilation hole 13e and is not flush with the ventilation hole 13e. In this way, a larger buffer space is formed between the protrusion 14a and the ventilation hole 13e, which is beneficial for the bubbles generated at the air outlet 10c after ventilation to be discharged through the ventilation hole 13e with a larger cross-sectional area.

[0124] In some embodiments, see Figures 3 to 5 The atomizer seat assembly 10 includes an atomizer top seat 11, and the atomizer top seat 11 includes a top seat top wall and a top seat side wall surrounding the top seat top wall. The top seat top wall and the top seat side wall are arranged to form a cavity. At least part of the structure of the mounting seat 13 is arranged in the cavity, and the top seat side wall is connected to the mounting seat 13 and / or the atomizer base 12.

[0125] Exemplarily, the atomizer seat assembly 10 includes a first seal 14 , which is sealingly clamped between the mounting seat 13 and the atomizer top seat 11 .

[0126] The appearance profile of the atomizing seat 11 is determined by the appearance profile of the seat top wall and the seat side walls surrounding the seat top wall.

[0127] At least part of the structure of the mounting seat 13 is disposed in the cavity means that the mounting seat 13 may be partially disposed in the cavity of the atomizing top seat 11 , or the entire structure may be disposed in the cavity.

[0128] The top seat side wall is connected to the mounting seat 13 and / or the atomizing base 12, which means that the top seat side wall can be connected to the mounting seat 13, the top seat side wall can be connected to the atomizing base 12, or the top seat side wall can be connected to both the mounting seat 13 and the atomizing base 12.

[0129] It should be noted that the specific connection method between the top seat side wall and the mounting seat 13 is not limited here, for example, it can be interference fit, snap-fit, etc. It is conducive to realizing the disassembly and assembly of the atomizer top seat 11 and the mounting seat 13, improving assembly efficiency and convenience of use.

[0130] In this embodiment, by setting the atomizer top seat 11 and sealingly clamping the first sealing member 14 between the mounting seat 13 and the atomizer top seat 11, on the one hand, it is beneficial to improve the connection reliability between the atomizer top seat 11, the mounting seat 13 and the atomizer base 12, and on the other hand, it can also improve the sealing performance of the liquid inlet channel 13a.

[0131] In some embodiments, see Figure 3 and Figure 4 The atomizer 100 includes a housing 50 having a accommodating chamber and an air outlet channel 51a. At least part of the structure of the atomizer seat assembly 10 is arranged in the accommodating chamber. The atomizer seat assembly 10 and the side wall of the accommodating chamber define a liquid storage chamber 100a for storing an aerosol generating substrate. The liquid inlet channel 13a is used to guide the aerosol generating substrate in the liquid storage chamber 100a to the atomizer core 20. The air outlet channel 51a is connected to the atomizer chamber 10a.

[0132] Exemplarily, the housing 50 includes a shell 52 and an air outlet pipe 51 , the shell 52 forms a receiving cavity, and the air outlet pipe 51 forms an air outlet channel 51 a.

[0133] Specifically, the air outlet pipe 51 is arranged along the top-bottom direction of the atomizer 100 , that is, the air outlet channel 51 a is arranged along the top-bottom direction of the atomizer 100 .

[0134] In some embodiments, see Figure 3 The air outlet pipe 51 and the housing 50 are an integrated structure, for example, an integrated injection molding. The integrated air outlet pipe 51 and the housing 50 can reduce the number of parts, reduce assembly time, and improve assembly efficiency.

[0135] Of course, the air outlet pipe 51 and the housing 50 may also be a separate structure.

[0136] In some other embodiments, the atomizer 100 further includes a suction member, which is disposed at one end of the air outlet pipe 51 away from the atomization chamber 10a.

[0137] The suction piece is, for example, a nozzle, that is, the user can inhale the aerosol through the nozzle.

[0138] For example, in some embodiments, the air outlet pipe 51 and the suction piece may be an integrated structure, for example, integrally injection molded. The integrated air outlet pipe 51 and the suction piece can reduce the number of parts, reduce assembly time, and improve assembly efficiency.

[0139] In other embodiments, the air outlet pipe 51 and the suction member may also be a split structure to facilitate production.

[0140] For example, see Figures 3 to 5 The atomizer 100 includes a second sealing member 30, which is sandwiched between the atomizer seat assembly 10 and the shell 50, and is used to seal the assembly gap between the atomizer seat assembly 10 and the shell 50, improve the sealing performance of the liquid storage chamber 100a, and improve the aerosol generating matrix in the liquid storage chamber 100a from flowing out of the assembly gap between the atomizer seat assembly 10 and the shell 50, thereby improving the service life of the aerosol generating device and the user experience.
