Description

Technical Field

[0001] This application relates to the field of aerosol generating devices, and particularly to an atomizing component mounting structure, an atomizing component, an atomizer, and an aerosol generating device. Background Technology

[0002] Common aerosol generating devices consist of an atomizer and a power supply, with the atomizer connected to the power supply. During operation, the power supply provides power to the atomizer.

[0003] The atomizer consists of a reservoir and an atomizing component, with the atomizing component located within the reservoir. The atomizing component is generally tubular, with one end connected to the bottom of the atomizer and the other end connected to the mouthpiece.

[0004] During use, the bottom of the atomizer may leak liquid, causing staining of clothing and reducing the user experience. Utility Model Content

[0005] This application provides an installation structure for an atomizing component, an atomizing component, an atomizer, and an aerosol generating device, which can reduce the risk of leakage from the atomizer and improve the user experience. The technical solution is as follows:

[0006] In a first aspect, embodiments of this application provide an installation structure for an atomizing component. The installation structure includes a bracket, one side of which has a plug-in groove for connecting an atomizing core.

[0007] The bottom of the insertion slot has at least one vent hole, and the bottom of the insertion slot includes a convex surface. The portion of the convex surface near the edge forms a first liquid storage space with the inner sidewall of the insertion slot.

[0008] In some examples, the minimum distance between the vent and the edge of the convex surface is greater than [a certain value].

[0009] In some examples, the convex surface is an arc surface.

[0010] In some examples, the bracket also has a mounting groove located on the other side of the bracket corresponding to the bottom of the insertion slot, the vent connecting the insertion slot and the mounting groove, and the bottom of the mounting groove including a concave surface;

[0011] The mounting structure also includes an annular liquid suction member located in the mounting groove. The inner wall of the annular liquid suction member is located inside the edge of the concave surface. The portion of the concave surface near the edge and the surface of the annular liquid suction member near the concave surface form a second liquid storage space.

[0012] In some examples, the concave surface is an arc surface.

[0013] In some examples, the orthographic projection of the vent hole onto the reference plane is located inside the orthographic projection of the annular liquid suction element onto the reference plane, which is a plane perpendicular to the depth direction of the insertion slot.

[0014] In some examples, the mounting structure further includes a first annular seal connected to the bracket, at least a portion of which is located on the side of the annular suction member away from the concave surface, to confine the annular suction member within the mounting groove.

[0015] In some examples, the inner diameter of the first annular seal is not greater than the inner diameter of the annular suction element.

[0016] In some examples, the mounting structure also includes an atomizer core cover, one end of which is inserted into the insertion slot.

[0017] In some examples, the mounting structure further includes an atomizer core bracket, one end of which is inserted into the insertion slot;

[0018] The atomizing core cover is fitted over the atomizing core bracket, and one end of the atomizing core cover located in the insertion slot is interference-fitted with the outer wall of the atomizing core bracket.

[0019] Secondly, embodiments of this application also provide an atomizing component, the atomizing component including an atomizing core and any of the mounting structures described in the first aspect, the atomizing core being connected to the insertion slot.

[0020] Thirdly, embodiments of this application also provide an atomizer, the atomizer including a liquid storage component and an atomizing component as described in the second aspect, the atomizing component being located in the liquid storage component.

[0021] Fourthly, embodiments of this application also provide an aerosol generating device, the aerosol generating device including a power source and an atomizer as described in the third aspect, the power source being used to supply power to the atomizer.

[0022] The beneficial effects of the technical solutions provided in this application include at least the following:

[0023] A connector slot is provided on one side of the bracket, which can be used to connect the atomizer coil. A vent hole is provided at the bottom of the connector slot, allowing air to enter the atomizer coil through the vent hole. Because the bottom of the connector slot includes a convex surface, liquid entering the connector slot can flow along the convex surface to its edge under gravity. The portion of the convex surface near the edge and the inner wall of the connector slot form a first liquid storage space. Liquid flowing along the convex surface to its edge and liquid flowing along the inner wall of the connector slot to its bottom can both be stored in this first liquid storage space, thus preventing liquid leakage through the vent hole, reducing the risk of leakage during atomizer use, and improving the user experience.

[0045] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 1 As shown, the aerosol generating device includes a power supply 100 and an atomizer 200. The power supply 100 is used to supply power to the atomizer 200.

[0046] Figure 2 This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of this application, as shown below. Figure 2 As shown, the atomizer 200 includes a liquid reservoir 210, an atomizing component 220, and a mouthpiece 230. The liquid reservoir 210 stores the aerosol matrix. The atomizing component 220 is located within the liquid reservoir 210 and is used to heat the aerosol matrix. The atomizing component 220 forms an atomization channel 220a. The mouthpiece 230 communicates with one end of the atomization channel 220a. The atomizing component 220 may include a mounting structure and an atomizing core 22, which is located within the mounting structure.

[0047] During the use of the aerosol generator, leakage may occur at the bottom of the atomizer 200. The leaked liquid may be the aerosol matrix stored in the liquid storage component 210, or it may be condensate formed in the atomization channel 220a. If this liquid leaks outside the atomizer 200, it can easily contaminate clothing and other items, affecting the user experience.

[0048] Figure 3 This is a schematic diagram of the installation structure of an atomizing component provided in an embodiment of this application, as shown below. Figure 3 As shown, the mounting structure includes a bracket 11, and one side of the bracket 11 has a plug groove 11a for connecting the atomizing core 22.

[0049] The atomizing coil 22 can be directly assembled into and connected to the insertion slot 11a, or it can be assembled to the bracket 11 via other structural components, indirectly connecting to the insertion slot 11a. For example, in this example, the mounting structure may also include an atomizing coil cover 13, one end of which is inserted into the insertion slot 11a. The atomizing coil 22 can be arranged in the atomizing coil cover 13, thereby indirectly connecting to the insertion slot 11a.

[0050] Figure 4 This is a schematic diagram of the internal structure of an installation structure provided in an embodiment of this application, as shown below. Figure 4 As shown, the bottom of the insertion groove 11a has at least one vent hole 11b, and the bottom of the insertion groove 11a includes a convex surface 11c. The portion of the convex surface 11c near the edge forms a first liquid storage space 11d with the inner sidewall of the insertion groove 11a.

[0051] A connector slot 11a is provided on one side of the bracket 11, which can be used to connect the atomizing core 22. A vent hole 11b is provided at the bottom of the connector slot 11a, allowing air to enter the atomizing core 22 through the vent hole 11b. Since the bottom of the connector slot 11a includes a convex surface 11c, liquid entering the connector slot 11a can flow along the convex surface 11c to its edge under gravity. The portion of the convex surface 11c near its edge forms a first liquid storage space 11d with the inner wall of the connector slot 11a. Liquid flowing along the convex surface 11c to its edge and liquid flowing along the inner wall of the connector slot 11a to its bottom can both be stored in the first liquid storage space 11d, thereby preventing liquid leakage through the vent hole 11b, reducing the risk of leakage during the use of the atomizer 200, and improving the user experience.

[0052] The leakage generated during the use of the atomizer 200 is actually a very small amount. Assuming the atomizer 200 is not damaged, the leakage is usually less than 1 ml, or even just a few drops. In other words, the amount of liquid entering the insertion slot 11a is relatively small. Although the first liquid storage space 11d formed by the portion of the convex surface 11c near the edge and the inner wall of the insertion slot 11a is relatively small, it is still sufficient to accommodate the liquid entering the insertion slot 11a, allowing the liquid to adhere to the inner wall of the insertion slot 11a and prevent leakage.

[0053] Furthermore, the first liquid storage space 11d surrounds and is close to the vent 11b. When the airflow passes through the vent 11b during the use of the atomizer 200, it can also promote the evaporation of the liquid accumulated in the first liquid storage space 11d.

[0054] The bottom of the insertion slot 11a may have one vent hole 11b or multiple vent holes 11b, that is, two or more vent holes 11b. As an example, Figure 5 This is a schematic diagram of the structure of a bracket provided in an embodiment of this application, as shown below. Figure 5 As shown, the bottom of the insertion slot 11a of the bracket 11 has four vent holes 11b. The multiple vent holes 11b can be distributed at intervals along the circumferential direction of the insertion slot 11a.

[0055] like Figure 5 As shown, the minimum distance between the vent 11b and the edge of the convex surface 11c is greater than 0.

[0056] The minimum distance between the vent hole 11b and the edge of the convex surface 11c refers to the distance between the closest points of the edges of the vent hole 11b and the edge of the convex surface 11c. This minimum distance is greater than 0, meaning that there is still a certain distance between the vent hole 11b and the edge of the convex surface 11c. This allows the first liquid storage space 11d to hold more liquid and prevents liquid adhering to the first liquid storage space 11d from entering the vent hole 11b.

[0057] As an example, the intersection of the edge of the convex surface 11c, the bottom of the insertion groove 11a, and the inner wall of the insertion groove 11a does not coincide. That is, the bottom of the insertion groove 11a may also include an annular surface located between the convex surface 11c and the inner wall of the insertion groove 11a.

[0058] In other possible implementations, the intersection of the edge of the convex surface 11c, the bottom of the insertion groove 11a, and the inner wall of the insertion groove 11a can coincide.

[0059] like Figure 4 As shown, the convex surface 11c is a circular arc surface. That is, the convex surface 11c can be part of a sphere.

[0060] Setting the convex surface 11c as an arc surface is beneficial for the liquid adhering to the middle of the convex surface 11c to flow along the convex surface 11c to the first liquid storage space 11d.

[0061] In other possible implementations, the convex surface 11c can also be a conical surface, or even a frustum surface, that is, including the top surface of the frustum and multiple side surfaces.

[0062] like Figure 4 As shown, the bracket 11 may also have a mounting groove 11g. A plug-in groove 11a is located on one side of the bracket 11, while the mounting groove 11g is located on the other side of the bracket 11, corresponding to the bottom of the plug-in groove 11a. A vent 11b connects the plug-in groove 11a and the mounting groove 11g, and the bottom of the mounting groove 11g includes a concave surface 11e.

[0063] The mounting structure may also include an annular liquid suction element 16, which is located in the mounting groove 11g. Figure 6 This is a schematic diagram of the assembly of a support and an annular liquid suction component provided in an embodiment of this application, as shown below. Figure 6 As shown, the inner wall of the annular liquid suction member 16 is located inside the edge of the concave surface 11e, and the portion of the concave surface 11e near the edge and the surface of the annular liquid suction member 16 near the concave surface 11e form a second liquid storage space 11f.

[0064] The inner wall of the annular liquid suction member 16 is located inside the edge of the concave surface 11e. This can mean that the annular liquid suction member 16 protrudes inward along the radial direction of the annular liquid suction member 16 relative to the edge of the concave surface 11e; or it can mean that the inner diameter of the annular liquid suction member 16 is smaller than the diameter of the edge of the concave surface 11e.

[0065] During the use of the atomizer 200, some liquid may directly adhere to the wall of the vent 11b and leak outwards. Liquid in the first liquid storage space 11d may also enter the vent 11b if it accumulates excessively or if the atomizer 200 is placed at an angle. By providing the concave surface 11e, the liquid entering the vent 11b can flow along the wall of the vent 11b to the concave surface 11e, and then along the edge of the concave surface 11e, where it is stored in the second liquid storage space 11f. The annular suction element 16 can also absorb the liquid in the second liquid storage space 11f, preventing excessive liquid accumulation and leakage outside the mounting groove 11g, further reducing the risk of leakage from the atomizer 200.

[0066] Furthermore, the second liquid storage space 11f surrounds the vent 11b and is relatively close to the vent 11b. During the use of the atomizer 200, when the airflow passes through the vent 11b, it can also promote the evaporation of the liquid accumulated in the second liquid storage space 11f and the liquid adsorbed by the annular liquid suction member 16.

[0067] For example, the annular absorbent 16 can be absorbent cotton.

[0068] In some examples, the orthographic projection of the vent 11b onto the reference plane lies inside the orthographic projection of the annular suction member 16 onto the reference plane. The reference plane is a plane perpendicular to the depth direction of the insertion groove 11a. That is, the annular suction member 16 and all the vents 11b are projected onto the same plane perpendicular to the depth direction of the insertion groove 11a, and all the vents 11b are located within the pattern enclosed by the inner wall of the annular suction member 16. This ensures that the vents 11b are not obstructed by the annular suction member 16, and that the annular suction member 16 does not obstruct the airflow entering the vents 11b.

[0069] like Figure 4 As shown, the mounting structure may further include a first annular seal 15. The first annular seal 15 is connected to the bracket 11. At least a portion of the first annular seal 15 is located on the side of the annular suction member 16 away from the concave surface 11e, so as to limit the annular suction member 16 in the mounting groove 11g.

[0070] While limiting the annular liquid suction member 16, the first annular seal 15 also blocks the gap between the annular liquid suction member 16 and the inner wall of the mounting groove 11g, thus sealing the gap and preventing the liquid in the second liquid storage space 11f and the liquid inside the annular liquid suction member 16 from leaking from the gap between the annular liquid suction member 16 and the inner wall of the mounting groove 11g.

[0071] For example, the inner diameter of the first annular seal 15 is not greater than the inner diameter of the annular liquid suction member 16, which can prevent the inner diameter of the first annular seal 15 from being too large, causing the surface of the annular liquid suction member 16 to be exposed, resulting in some of the liquid in the annular liquid suction member 16 flowing out along the inner wall of the first annular seal 15.

[0072] In this example, the inner diameter of the first annular seal 15 is the same as the inner diameter of the annular liquid suction member 16, thereby preventing some of the liquid in the annular liquid suction member 16 from flowing out along the inner wall of the first annular seal 15, and also avoiding the inner diameter of the first annular seal 15 being too small and affecting the airflow.

[0073] Figure 7 This is a schematic diagram of the internal structure of an atomizing component installation structure provided in an embodiment of this application, as shown below. Figure 7As shown, the mounting structure also includes a second annular seal 12. The second annular seal 12 is located on one side of the bracket 11, surrounds the insertion groove 11a, and is connected to the bracket 11. One end of the atomizer core cover 13 passes through the second annular seal 12 and is inserted into the insertion groove 11a. The outer wall of the atomizer core cover 13 has an outer flange 131, which seals against the side of the second annular seal 12 away from the bracket 11. The outer wall of the atomizer core cover 13 seals against the inner wall of the second annular seal 12.

[0074] By providing a second annular seal 12 on one side of the bracket 11, one end of the atomizing core cover 13 is inserted into the insertion groove 11a of the bracket 11 through the second annular seal 12, forming a seal through the cooperation between the second annular seal 12 and the atomizing core cover 13. The outer wall of the atomizing core cover 13 is sealed to the inner wall of the second annular seal 12, thus forming a first seal. The outer wall of the atomizing core cover 13 also has an outer flange 131, which is sealed to the side of the second annular seal 12 away from the bracket 11, thus forming a second seal. By forming two seals with one second annular seal 12 and the atomizing core cover 13, the number of seals required can be reduced, thereby reducing the number of components included in the installation structure, making the assembly process of the atomizer 200 more convenient, and improving the generation efficiency. In addition, in related technologies, during the assembly of multiple seals, the assembled seals may be squeezed, which may cause seal failure and increase the risk of leakage of the atomizer 200. In this embodiment, the number of seals is reduced, which avoids excessive compression of the seals, reduces the possibility of seal failure, and reduces the risk of leakage of the atomizer 200.

[0075] like Figure 7 As shown, the inner wall of the second annular seal 12 has a first annular rib 121, which abuts against the outer wall of the atomizing core cover 13.

[0076] The inner wall of the second annular seal 12 is abutted against the outer wall of the atomizing core cover 13 to form a sealing fit. By further forming a first annular rib 121 on the inner wall of the second annular seal 12, so that the first annular rib 121 abuts against the outer wall of the atomizing core cover 13, the squeezing action between the second annular seal 12 and the atomizing core cover 13 can be strengthened, thereby improving the sealing performance between the inner wall of the second annular seal 12 and the outer wall of the atomizing core cover 13.

[0077] In other possible implementations, the inner wall of the second annular seal 12 may also be provided with multiple first annular ribs 121, for example, two or more first annular ribs 121. The multiple first annular ribs 121 may be spaced apart along the axial direction of the second annular seal 12. The multiple first annular ribs 121 abut against the outer wall of the atomizing core cover 13. By forming multiple seals through the multiple first annular ribs 121, the sealing performance between the inner wall of the second annular seal 12 and the outer wall of the atomizing core cover 13 can be further improved.

[0078] like Figure 7 As shown, the second annular seal 12 has a countersunk hole 12a on the side away from the bracket 11, and the outer flange 131 is located in the countersunk hole 12a.

[0079] The outer flange 131 can fit against the surface of the second annular seal 12 to form a seal. By further forming a countersunk hole 12a on the surface of the second annular seal 12, the outer flange 131 is recessed into the countersunk hole 12a. The aerosol matrix needs to pass through the gap between the outer flange 131 and the side wall of the countersunk hole 12a, the gap between the outer flange 131 and the bottom surface of the countersunk hole 12a, and the gap between the inner side wall of the second annular seal 12 and the outer side wall of the atomizing core cover 13 in sequence before leakage is possible. The setting of the countersunk hole 12a extends the leakage path and helps to reduce the risk of leakage.

[0080] In the atomizer 200, the mounting structure is assembled inside the liquid storage assembly 210, and the outer wall of the second annular seal 12 also forms a seal with the liquid storage assembly 210. This causes the second annular seal 12 to be subjected to radial inward compression, which helps to reduce the gap between the side wall of the countersunk hole 12a and the outer flange 131, thereby further improving the sealing performance.

[0081] In some examples, the sidewall of the countersunk hole 12a may abut against the outer flange 131.

[0082] The sidewall of the countersunk hole 12a abuts against the outer flange 131, thus forming another seal, further improving the sealing performance and reducing the risk of leakage.

[0083] In the atomizer 200, the second annular seal 12 is squeezed radially inward by the liquid storage assembly 210, which makes the sidewall of the countersunk hole 12a and the outer flange 131 squeeze each other more tightly, further improving the sealing performance.

[0084] Figure 8 This is a cross-sectional schematic diagram of a second annular seal provided in an embodiment of this application, as shown below. Figure 8 As shown, in some examples, the bottom surface of the countersunk hole 12a may have a second annular rib 122, which surrounds the atomizing core outer cover 13. The second annular rib 122 abuts against the surface of the outer flange 131.

[0085] The outer flange 131 is fitted to the surface of the second annular seal 12 to form a seal. By further forming a second annular rib 122 on the bottom surface of the countersunk hole 12a, so that the second annular rib 122 abuts against the surface of the outer flange 131, the squeezing action between the second annular seal 12 and the outer flange 131 can be strengthened, thereby improving the sealing performance between the second annular seal 12 and the atomizing core cover 13.

[0086] In other possible implementations, the bottom surface of the countersunk hole 12a may also be provided with multiple second annular ribs 122, for example, two or more second annular ribs 122. The multiple second annular ribs 122 may be distributed radially at intervals along the countersunk hole 12a; for example, the multiple second annular ribs 122 may be arranged concentrically. The multiple second annular ribs 122 abut against the outer side wall of the outer flange 131. By forming multiple seals through the multiple second annular ribs 122, the sealing performance between the second annular seal 12 and the outer flange 131 can be further improved.

[0087] Figure 9 This is a cross-sectional schematic diagram of an atomizing core cover provided in an embodiment of this application, as shown below. Figure 9 As shown, in some examples, the outer flange 131 may have a third annular rib 132 on the side near the bottom surface of the countersunk hole 12a, the third annular rib 132 surrounding the atomizing core cover 13. The third annular rib 132 abuts against the bottom surface of the countersunk hole 12a.

[0088] When the outer flange 131 is in contact with the surface of the second annular seal 12, the third annular rib 132 can squeeze the second annular seal 12, causing the second annular seal 12 to be recessed, thereby making it fit more tightly with the outer flange 131, so as to improve the sealing performance between the second annular seal 12 and the outer flange 131.

[0089] In other possible implementations, a plurality of third annular ribs 132 may also be provided on the side of the outer flange 131 near the bottom surface of the countersunk hole 12a, for example, two or more second annular ribs 122 may be provided. The plurality of third annular ribs 132 may be radially spaced along the outer flange 131, for example, the plurality of third annular ribs 132 may be concentrically arranged. The plurality of third annular ribs 132 abut against the bottom surface of the countersunk hole 12a. By forming multiple seals through the plurality of third annular ribs 132, the sealing performance between the second annular seal 12 and the outer flange 131 can be further improved.

[0090] like Figure 7As shown, the bracket 11 also has an annular boss 111 on the side near the second annular seal 12, and the annular boss 111 surrounds the insertion groove 11a. The second annular seal 12 has an annular slot 12b on the side near the bracket 11, and the annular boss 111 is inserted into the annular slot 12b.

[0091] When assembling the second annular seal 12 and the bracket 11, the contact area between the second annular seal 12 and the bracket 11 can be increased by using the cooperation between the annular slot 12b and the annular boss 111, making the assembly of the second annular seal 12 and the bracket 11 more secure.

[0092] In addition, the second annular seal 12 will also be subjected to radial compression, such as radial outward compression from the atomizing core cover 13 and radial inward compression from the liquid storage assembly 210. The annular boss 111 can provide radial support for the second annular seal 12, making the second annular seal 12 more stable and preventing excessive deformation of the second annular seal 12 from affecting the sealing performance or even causing failure.

[0093] like Figure 7 As shown, the outer wall of the second annular seal 12 has two fourth annular ribs 123, which surround the annular boss 111. The radially inward projection of the fourth annular ribs 123 is located on the outer surface of the annular boss 111.

[0094] The radially inward projection of the fourth annular rib 123 can be an orthographic projection of the fourth annular rib 123 onto a cylindrical surface that can extend infinitely at both ends of the outer surface of the annular boss 111. For example, the annular boss 111 is circular, and the cylindrical surface on which the outer surface of the annular boss 111 is located can be a cylindrical surface.

[0095] In the atomizer 200, the fourth annular rib 123 is used to press against the liquid storage assembly 210 to form a seal. The pressing direction of the liquid storage assembly 210 against the fourth annular rib 123 is radially along the fourth annular rib 123. The radially inward projection of the fourth annular rib 123 is located on the outer surface of the annular boss 111, so that the fourth annular rib 123 can be radially supported by the annular boss 111, thereby avoiding excessive deformation of the second annular seal 12.

[0096] In other possible implementations, the outer wall of the second annular seal 12 may also be provided with other numbers of fourth annular ribs 123, for example, one or more fourth annular ribs 123. The multiple fourth annular ribs 123 may be distributed at intervals along the axial direction of the second annular seal 12. The multiple fourth annular ribs 123 are respectively used to abut against the liquid storage assembly 210. By forming multiple seals with multiple fourth annular ribs 123, the sealing performance between the liquid storage assembly 210 and the atomizing assembly 220 can be improved, reducing the risk of leakage.

[0097] like Figure 7 As shown, the annular slot 12b can separate the first annular rib 121 and the fourth annular rib 123, which allows the annular boss 111 to separate the first annular rib 121 and the fourth annular rib 123. This makes the radially outward and radially inward pressure on the second annular seal 12 independent. That is, the radially outward pressure of the atomizing core cover 13 on the second annular seal 12 will not or almost not act on the liquid storage assembly 210 through the second annular seal 12. Similarly, the radially inward pressure of the liquid storage assembly 210 on the second annular seal 12 will not or almost not act on the atomizing core cover 13 through the second annular seal 12. The magnitudes of the compressive forces on the inner and outer walls of the second annular seal 12 do not affect each other, allowing the first annular rib 121 and the fourth annular rib 123 to be designed separately to achieve their respective sealing requirements.

[0098] In this example, the annular boss 111 separates the inner wall of the second annular seal 12 and the fourth annular rib 123.

[0099] The axial length of the inner wall of the second annular seal 12 can be less than the axial length of the outer wall. The radially outward projection of the inner wall of the second annular seal 12 is located on the inner surface of the annular boss 111, thereby separating the inner wall of the second annular seal 12 from the fourth annular rib 123. In this way, the compression on the inner wall of the second annular seal 12 will act on the annular boss 111, without affecting the magnitude of the compression force between the fourth annular rib 123 and the liquid storage assembly 210.

[0100] like Figure 7 As shown, the mounting structure may further include an atomizer core support 14. One end of the atomizer core support 14 passes through the second annular seal 12 and is inserted into the insertion groove 11a. The atomizer core cover 13 is fitted over the atomizer core support 14, and one end of the atomizer core cover 13 located in the insertion groove 11a is press-fitted with the outer wall of the atomizer core support 14.

[0101] The atomizer core holder 14 is used to accommodate the atomizer core 22. By also inserting one end of the atomizer core holder 14 into the insertion slot 11a to form an interference fit with the atomizer core cover 13, leakage at the connection between the atomizer core holder 14 and the atomizer core cover 13 can be avoided.

[0102] Both the atomizer core cover 13 and the atomizer core support 14 can have a hollow structure, such as through holes, so that the aerosol matrix in the liquid storage component 210 can enter the inside of the atomizer core support 14.

[0103] Figure 10 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application, as shown below. Figure 10 As shown, the atomizing assembly 220 includes an atomizing core 22 and a mounting structure, which can be as follows: Figures 3-9 Any of the installation structures shown. Figure 10 China only Figure 7 The installation structure shown is an example.

[0104] The atomizing core 22 is connected to the insertion slot 11a. For example, the atomizing core 22 is located in the atomizing core cover 13 and is connected to the insertion slot 11a through the atomizing core cover 13.

[0105] As an example, the mounting structure also includes an atomizer core holder 14, in which the atomizer core 22 is located.

[0106] The atomizing core 22 includes a liquid guide 221, a heating element 222, and leads (not shown). The liquid guide 221 and the heating element 222 are located within the atomizing core support 14. The leads are electrically connected to the heating element 222. The atomizing core support 14 is fitted over the liquid guide 221 and serves to support the liquid guide 221.

[0107] The atomizer core holder 14 provides space within the liquid storage assembly 210 to accommodate the liquid guide 221 and the heating element 222. The aerosol matrix entering the atomizer core holder 14 can be absorbed by the liquid guide 221. The heating element 222 heats the aerosol matrix in the liquid guide 221, causing it to vaporize.

[0108] The material and structure of the heating element 222 are not limited, as long as it can generate heat. For example, the heating element 222 may include at least one of the following: heating mesh, heating film, heating wire, and heating plate.

[0109] This application also provides an atomizer. Figure 11 This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of this application, as shown below. Figure 11 As shown, the atomizer 200 may include a liquid reservoir 210 and, as shown, a liquid storage assembly 210 and a liquid storage assembly 210. Figure 10 The atomizing component 220 is shown. The atomizing component 220 is located in the liquid storage component 210 and is used to heat the aerosol matrix to form an aerosol.

[0110] The liquid storage assembly 210 may include a liquid reservoir housing 211, the interior of which forms a liquid reservoir for containing an aerosol matrix. The support 11 may be detachably connected to the liquid reservoir housing 211, and the outer wall of the second annular seal 12 may be in a sealing fit with the inner wall of the liquid reservoir housing 211.

[0111] In some examples, the liquid storage assembly 210 may also include a liquid storage element, which may be located within the liquid reservoir housing 211. For example, the liquid storage element may be a liquid storage cotton that has been adsorbed / wetted with an aerosol matrix.

[0112] This application also provides an aerosol generating device, which includes a power supply and an atomizer 200. The power supply 100 supplies power to the atomizing assembly 220.

[0113] For example, the atomizer 200 of the aerosol generating device may be Figure 2 or Figure 11 The atomizer 200 is shown.

[0114] In some examples, the power supply 100 is detachably connected to the atomizer 200. Because the power supply 100 is detachably connected to the atomizer 200, it is easy to replace the atomizer 200.

[0115] In other examples, the power supply 100 and the atomizer 200 may be fixedly connected. For example, the housing of the power supply 100 and the liquid tank housing 211 of the atomizer 200 may be an integral structure.
