Description

Technical Field

[0001] This utility model relates to the field of atomization technology, specifically to an atomizer and an aerosol generating device. Background Technology

[0002] Aerosol generating devices are used to generate aerosols for users to inhale.

[0003] The aerosol generating device includes an atomizer, which stores an aerosol generating matrix. The aerosol generating matrix can be contacted and absorbed by the atomizing components in the atomizer. The atomizing components convert the aerosol generating matrix into aerosols through heating or other means.

[0004] In related technologies, the aerosol generating matrix is ​​liquid. Therefore, after a certain amount of the aerosol generating matrix is ​​consumed, a cavity will be formed in the space originally used to store the aerosol generating matrix. As the posture of the aerosol generating device changes, the aerosol generating matrix will flow, causing the position of the cavity to change. In some cases, the cavity will block the atomizing component from contacting the aerosol generating matrix, making it difficult for the atomizing component to contact the aerosol generating matrix. This will prevent the atomizing component from generating aerosol and affect the normal service life of the atomizing component. Utility Model Content

[0005] In view of this, the present invention aims to provide an atomizer and aerosol generating device that facilitates maintaining contact between the aerosol generating matrix and the atomizing component.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0007] This utility model embodiment provides an atomizer, the atomizer comprising:

[0008] case;

[0009] The mounting base is provided with an airflow channel and a mounting hole. The airflow channel passes through the mounting base, and the mounting hole connects the airflow channel to the outside of the mounting base. The housing and the mounting base together form a liquid storage cavity.

[0010] An atomizing assembly is provided to seal the mounting hole. The atomizing assembly includes an atomizing body, a liquid guiding component, and a liquid storage component. A portion of the atomizing body is in fluid communication with the airflow channel, and the liquid storage component is in fluid communication with the liquid storage chamber. Both the liquid storage component and the liquid guiding component are provided with pores for absorbing the aerosol generation matrix. The porosity of the liquid guiding component is greater than that of the liquid storage component. The liquid guiding component is located between the atomizing body and the liquid storage component and is in fluid communication with both.

[0011] In some embodiments, the liquid reservoir is attached to the liquid guide.

[0012] In some embodiments, the liquid reservoir is located on one side of the liquid guide along a first direction, and in a projection plane perpendicular to the first direction, the projection of the liquid guide is located within the projection range of the liquid reservoir.

[0013] In some embodiments, the atomizing assembly further includes a bracket, the bracket including a first mounting cavity, a second mounting cavity and a connecting hole, a portion of the first mounting cavity being open and communicating with the airflow channel, a portion of the second mounting cavity being open and communicating with the liquid storage cavity, the connecting hole connecting the first mounting cavity and the second mounting cavity, at least a portion of the liquid guiding element being located in the first mounting cavity, and at least a portion of the liquid storage element being located in the second mounting cavity.

[0014] In some embodiments, the first mounting cavity and the second mounting cavity are spaced apart along a first direction, and both the first mounting cavity and the second mounting cavity are open along the first direction but in opposite directions.

[0015] In some embodiments, the bracket further includes a connecting hole that connects the first mounting cavity to the outside of the bracket. The atomizing assembly further includes a first sealing ring, a second sealing ring, and a connector. At least a portion of the first sealing ring is disposed within the first mounting cavity and sandwiched between the bracket and the liquid guiding member. The second sealing ring is sandwiched between the bracket and the mounting base. The connector passes through the connecting hole to connect the first sealing ring and the second sealing ring. The first sealing ring, the second sealing ring, and the connector are an integral structure.

[0016] In some embodiments, the bracket includes a mounting plate and a first limiting plate. The connecting hole penetrates the mounting plate along a first direction. The first limiting plate is disposed on one side of the mounting plate along the first direction and extends along the first direction. There are two first limiting plates, which are spaced apart to jointly enclose the first mounting cavity and the connecting hole. A first sealing ring is sandwiched between the liquid guide and the mounting plate along the first direction. A second sealing ring is sandwiched between the mounting base and the mounting plate along the first direction. The second sealing ring is circumferentially disposed on the two first limiting plates away from the first mounting cavity.

[0017] In some embodiments, the housing has a cavity that is open on one side along a second direction. At least a portion of the mounting base is inserted into the cavity through the open position to form the liquid storage chamber. The atomizer also includes a sealing sleeve, which includes a sleeve body, a first sealing rib, and a second sealing rib. A portion of the mounting base located within the cavity covers the sleeve body. The sleeve body has a through-hole for liquid flow. The liquid storage component is in fluid communication with the liquid storage chamber through the through-hole. The first sealing rib and the second sealing rib are both located on the surface of the sleeve body opposite to the mounting base and sandwiched between the sleeve body and the housing. The first sealing rib surrounds the circumference of the sleeve body along the second direction and is located on the side of the through-hole near the open position of the cavity. The second sealing rib is located on the side of the first sealing rib away from the open position of the cavity and is connected to the first sealing rib to jointly enclose a lateral sealing area. The through-hole is located on the side of the sleeve body perpendicular to the second direction, and at least a portion of the lateral sealing area is located on the other side.

[0018] In some embodiments, the cavity is provided with a mounting post that extends along the second direction and has a through discharge channel. A portion of the mounting post is inserted into the airflow channel to make the discharge channel communicate with the airflow channel, and a portion of the sleeve body is sandwiched between the airflow channel and the mounting post.

[0019] This application also provides an aerosol generating device, including any of the atomizers described in the foregoing embodiments.

[0020] The atomizer in this embodiment of the application, by setting a liquid storage component, allows the liquid storage component to store a portion of the aerosol generating matrix through contact with the aerosol generating matrix. This ensures that regardless of the atomizer's orientation, a portion of the aerosol generating matrix can be supplied to the atomizing body through the liquid storage component. This reduces the probability of the atomizing body failing to heat the aerosol generating matrix and causing dry burning when the atomizer is in any orientation or when the aerosol generating matrix is ​​mixed with air bubbles. It also reduces the probability of the generated aerosol having a burnt smell, which is beneficial to improving the user experience. Attached Figure Description

[0041] This application provides an atomizer 10, see the following embodiment. Figures 1 to 5 , Figure 10 The atomizer 10 includes a housing 12, a mounting base 13, and an atomizing assembly 11.

[0042] The mounting base 13 is provided with an airflow channel 13a and a mounting hole 13b. The airflow channel 13a passes through the mounting base 13, and the mounting hole 13b connects the airflow channel 13a with the outside of the mounting base 13. The housing 12 and the mounting base 13 together form a liquid storage cavity 12a.

[0043] The atomizing component 11 seals the mounting hole 13b. The atomizing component 11 includes an atomizing body 111, a liquid guide 117, and a liquid storage component 112. The airflow channel 13a passes through the mounting base 13. The liquid storage component 112 is in fluid communication with the liquid storage chamber 12a. Both the liquid storage component 112 and the liquid guide 117 are provided with pores for absorbing the aerosol generation matrix. The porosity of the liquid guide 117 is greater than that of the liquid storage component 112. The liquid guide 117 is located between the atomizing body 111 and the liquid storage component 112 and is in fluid communication with both.

[0044] The airflow channel 13a passes through the mounting base 13, meaning that the openings at both ends of the airflow channel 13a are connected to the outside of the mounting base 13.

[0045] Airflow can enter from one end of airflow channel 13a and exit from the other end.

[0046] The storage chamber 12a is used to store the aerosol generation matrix. The aerosol generation matrix is ​​a fluid medium that can flow within the storage chamber 12a.

[0047] The atomizing component 11 is used to atomize the aerosol generation matrix by means of heating or other methods.

[0048] The atomizing component 11 seals the mounting hole 13b, which on the one hand makes it difficult for the aerosol generating matrix in the liquid storage chamber 12a and the airflow in the airflow channel 13a to directly exchange and flow between the airflow channel 13a and the liquid storage chamber 12a; on the other hand, the atomizing component 11 can absorb the aerosol generating matrix from the liquid storage chamber 12a and mix the atomized aerosol generating matrix with the air in the airflow channel 13a to form an aerosol.

[0049] The atomizer 111 can convert the aerosol generating matrix that it contacts or absorbs into aerosols through heating or other means.

[0050] The atomizing body 111 is in fluid communication with the airflow channel 13a, so that the atomized aerosol matrix of the atomizing body 111 can be mixed with the airflow in the airflow channel 13a to form an aerosol.

[0051] At least a portion of the liquid storage component 112 is located within the liquid storage cavity 12a, such that the aerosol generating matrix within the liquid storage cavity 12a can come into contact with the liquid storage component 112, thereby absorbing and storing a portion of the aerosol generating matrix into the pores.

[0052] It is understandable that the aerosol matrix located in the pores, due to the capillary effect generated by its surface tension, adheres to the inner wall of the pores, making it difficult to detach from the pores and return to the liquid storage chamber 12a under the action of external forces such as gravity.

[0053] The liquid storage element 112 is in fluid communication with the atomizer 111, and at least some of the pores are in communication with each other, so that the aerosol generation matrix can pass through the liquid storage element 112 and be delivered to the liquid guide element 117 in fluid communication with the liquid storage element 112.

[0054] Understandably, because the porosity of the liquid guiding component 117 is greater than that of the liquid storage component 112, the aerosol generating matrix flows from the pores of the liquid storage component 112 into the pores of the liquid guiding component 117. In other words, a flow path of the aerosol generating matrix is ​​formed from the liquid storage component 112 → the liquid guiding component 117 → the atomizer 111.

[0055] As the atomizer 111 consumes the aerosol generating matrix, the aerosol generating matrix in the pores of the liquid storage component 112 can continuously flow into the pores of the liquid guide component 117. The aerosol generating matrix flowing out of the pores of the liquid guide component 117 comes into contact with the liquid guide component 117, so that the atomizer 111 can continuously atomize the aerosol generating matrix.

[0056] In this embodiment, the atomizer 10, by providing a liquid storage component 112, allows the liquid storage component 112 to store a portion of the aerosol generating matrix through contact with the aerosol generating matrix. This ensures that regardless of the orientation of the atomizer 10, a portion of the aerosol generating matrix can be provided to the atomizing body 111 through the liquid storage component 112. This reduces the probability that the atomizing body 111 will not be able to contact the aerosol generating matrix when the atomizer 10 is in any orientation, which is beneficial to improving the user experience.

[0057] The specific structure and material of the pores formed by the liquid storage component 112 are not limited, such as fiber structures woven or twisted from cotton, sponge, polyester, nylon and other chemical fibers.

[0058] It is understandable that the size of the pores in the liquid storage component 112 and the liquid guiding component 117 may or may not be visible to the naked eye.

[0059] In some embodiments, see Figure 4 and Figure 5 The liquid storage component 112 is attached to the liquid guiding component 117.

[0060] In this way, fluid communication is achieved between the liquid storage component 112 and the liquid guiding component 117, shortening the flow path of the aerosol generation matrix between the liquid storage component 112 and the liquid guiding component 117, reducing the risk of interruption in the supply of aerosol generation matrix to the liquid guiding component 117, and enabling the aerosol generation matrix stored in the liquid storage component 112 to come into contact with the atomizer 111 more promptly through the liquid guiding component 117, further reducing the probability of problems such as dry burning of the atomizer 111.

[0061] In some embodiments, see Figure 4 and Figure 5 The liquid storage component 112 is located on one side of the liquid guiding component 117 along the first direction. In the projection plane perpendicular to the first direction, the projection of the liquid guiding component 117 is located within the projection range of the liquid storage component 112.

[0062] This increases the area of ​​fluid communication between the liquid guide 117 and the liquid storage 112, thereby improving the effect of the liquid storage 112 in supplying the aerosol generation matrix to the liquid guide 117. In addition, it increases the volume of the liquid storage 112, thereby increasing the total volume of the pores in the liquid storage 112 and increasing the amount of aerosol generation matrix that can be stored in the liquid storage 112.

[0063] It is understandable that the liquid storage component 112 is located on one side of the liquid guiding component 117 along the first direction, and the atomizer 111 is located on the other side.

[0064] In some embodiments, see Figure 4 , Figure 6 and Figure 7 The atomizing assembly 11 also includes a bracket 113, which includes a first mounting cavity 113a, a second mounting cavity 113b, and a connecting hole 113c. A portion of the first mounting cavity 113a is open and communicates with the airflow channel 13a, a portion of the second mounting cavity 113b is open and communicates with the liquid storage cavity 12a, and the connecting hole 113c connects the first mounting cavity 113a and the second mounting cavity 113b. At least a portion of the liquid guide 117 is located in the first mounting cavity 113a, and at least a portion of the liquid storage component 112 is located in the second mounting cavity 113b.

[0065] The bracket 113 provides a mounting position for the liquid guide 117 and the liquid reservoir 112. The bracket 113 is fixed to the mounting base 13 to fix the positions of the atomizer 111 and the liquid reservoir 112.

[0066] During the assembly of the atomizing component 11, the liquid guide 117 can be installed into the first mounting cavity 113a through the open position of the first mounting cavity 113a, and the inner wall of the first mounting cavity 113a plays a role in constraining and positioning the liquid guide 117; through the open position of the first mounting cavity 113a, the atomizing body 111 can come into contact with the liquid guide 117.

[0067] During the assembly of the atomizing component 11, the liquid storage component 112 can be installed into the second mounting cavity 113b through the open position of the second mounting cavity 113b, and the inner wall of the second mounting cavity 113b plays a role in constraining and positioning the liquid storage component 112; through the open position of the second mounting cavity 113b, the liquid storage component 112 can achieve fluid communication with the liquid storage cavity 12a.

[0068] The connecting hole 113c connects the first mounting cavity 113a and the second mounting cavity 113b, so that the aerosol generation matrix can pass through the connecting hole 113c and be absorbed by the liquid guiding element 117 located in the first mounting cavity 113a.

[0069] In some embodiments, see Figure 4 A portion of the liquid storage component 112 passes through the connecting hole 113c and contacts the liquid guiding component 117, thereby utilizing the space within the connecting hole 113c, which is beneficial to increasing the amount of aerosol generation matrix that can be stored within the liquid storage component 112.

[0070] In some embodiments, see Figure 4 The first mounting cavity 113a and the second mounting cavity 113b are spaced apart along the first direction. Both the first mounting cavity 113a and the second mounting cavity 113b are open along the first direction and their opening directions are opposite.

[0071] This allows for the simultaneous installation of the liquid guide 117 and the liquid reservoir 112 along the first direction during the assembly of the atomizing assembly 11, thereby improving assembly efficiency. Furthermore, the inner walls of the first mounting cavity 113a and the second mounting cavity 113b of the connecting hole can respectively restrict the relative positions of the liquid guide 117 and the liquid reservoir 112 along the first direction.

[0072] It is understandable that the connecting hole 113c penetrates the bracket 113 along the first direction.

[0073] In some embodiments, see Figure 6 The bracket 113 is provided with a positioning post 1131 protruding in the first direction on at least one side of the bracket 113, so that during the automated assembly of the atomizing component 11, the positioning post 1131 can be used to identify the position of the liquid guide 117 and the liquid storage component 112, and the positioning post 1131 can be used to fix the position of the bracket 113.

[0074] In some embodiments, see Figure 5 and Figure 10 The mounting hole 13b extends along a first direction, with one side open and communicating with the airflow channel 13a, and the other side communicating with the liquid storage chamber 12a.

[0075] This facilitates the installation of the atomizing component 11 into the mounting hole 13b along the first direction during the assembly process, and simultaneously enables the atomizing body 111 mounted on the liquid guide 117 to be in fluid communication with the airflow channel 13a on one side along the first direction, while the liquid storage component 112 is exposed to the outside on the other side along the first direction, so that the liquid storage component 112 can be in fluid communication with the liquid storage chamber 12a after the subsequent assembly of the housing 12.

[0076] In some embodiments, see Figure 4 The atomizing assembly 11 also includes a first sealing ring 114 and a second sealing ring 115. At least a portion of the first sealing ring 114 is disposed in the first mounting cavity 113a and sandwiched between the bracket 113 and the liquid guide 117. The second sealing ring 115 is sandwiched between the bracket 113 and the mounting base 13.

[0077] It is understandable that both the first sealing ring 114 and the second sealing ring 115 can undergo elastic deformation to achieve the sealing function.

[0078] The first sealing ring 114 reduces the probability that the aerosol generation matrix flowing out of the liquid storage component 112 will leak into the airflow channel 13a through the gap between the support 113 and the liquid guide 117.

[0079] The second sealing ring 115 reduces the probability that the aerosol generation matrix in the liquid storage chamber 12a will leak into the airflow channel 13a through the gap between the bracket 113 and the mounting base 13.

[0080] The specific material of the first sealing ring 114 is not limited, such as silicone, rubber, etc.

[0081] The specific material of the second sealing ring 115 is not limited, such as silicone, rubber, etc.

[0082] In some embodiments, see Figure 7 and Figure 8 The bracket 113 also includes a connecting hole 113d, which connects the first mounting cavity 113a to the outside of the bracket 113. The atomizing assembly 11 also includes a connector 116, which passes through the connecting hole 113d to connect the first sealing ring 114 and the second sealing ring 115. The first sealing ring 114, the second sealing ring 115 and the connector 116 are an integral structure.

[0083] In other words, the first sealing ring 114, the second sealing ring 115, and the connector 116 are different parts of the same component.

[0084] In this way, the first sealing ring 114, the second sealing ring 115 and the connector 116 can be installed on the bracket 113 simultaneously, which helps to simplify the assembly steps of the atomizing component 11 and improve assembly efficiency.

[0085] The specific method by which the first sealing ring 114, the second sealing ring 115, and the connector 116 form an integrated structure is not limited, such as injection molding, additive manufacturing, etc.

[0086] In some embodiments, see Figure 4 and Figure 7 The bracket 113 includes a mounting plate 1132 and a first limiting plate 1133. A connecting hole 113c penetrates the mounting plate 1132 along a first direction. The first limiting plate 1133 is disposed on one side of the mounting plate 1132 along the first direction and extends along the first direction. There are two first limiting plates 1133. The two first limiting plates 1133 are spaced apart to jointly enclose a first mounting cavity 113a and a connecting hole 113d. A first sealing ring 114 is sandwiched between the atomizing body 111 and the mounting plate 1132 along the first direction. A second sealing ring 115 is sandwiched between the mounting base 13 and the mounting plate 1132 along the first direction. The second sealing ring 115 is circumferentially disposed on the two first limiting plates 1133 away from the first mounting cavity 113a.

[0087] It is understandable that the first limiting plate 1133 is inserted between the first sealing ring 114 and the second sealing ring 115.

[0088] The first limiting plate 1133 can limit the position of the first sealing ring 114 and the second sealing ring 115.

[0089] During the assembly of the atomizing component 11, the first sealing ring 114, the second sealing ring 115 and the connector 116 can be assembled along the first direction, and then the atomizing body 111 can be assembled along the same direction.

[0090] This allows the liquid guide 117, bracket 113, first sealing ring 114, second sealing ring 115 and connector 116 to be assembled along the first direction during the assembly of the atomizing component 11, without the need for any other directions, which helps to improve assembly efficiency.

[0091] In some embodiments, see Figure 4 and Figure 6 The bracket 113 also includes a second limiting plate 1134, which is disposed on the side of the mounting plate 1132 opposite to the first limiting plate 1133 along the first direction and extends along the first direction. The second limiting plate 1134 surrounds and forms a second mounting cavity 113b.

[0092] This allows the liquid storage component 112 to be assembled along the other direction of the first direction, which helps to improve assembly efficiency.

[0093] In some embodiments, see Figure 6 The second limiting plate 1134 and the positioning post 1131 are located on the same side of the mounting plate 1132 along the first direction, so as to seal the mounting hole 13b of the assembled atomizing component 11 along the first direction.

[0094] In some embodiments, see Figure 3 and Figure 9 The housing 12 has a cavity, which is open on one side along the second direction. At least a portion of the mounting base 13 is inserted into the cavity through the open position to form a liquid storage chamber 12a. The atomizer 10 also includes a sealing sleeve 14, which includes a sleeve body 141 and a first sealing rib 142. A portion of the mounting base 13 located inside the cavity covers the sleeve body 141. The sleeve body 141 has a through liquid passage hole 141a. The liquid storage component 112 is in fluid communication with the liquid storage chamber 12a through the liquid passage hole 141a. The first sealing rib 142 is located on the surface of the sleeve body 141 opposite to the mounting base 13 and is sandwiched between the sleeve body 141 and the housing 12. The first sealing rib 142 surrounds the circumference of the sleeve body 141 along the second direction and is located on the side of the liquid passage hole 141a near the open position of the cavity.

[0095] The first sealing rib 142 is a ring structure.

[0096] The sealing fit between the sealing sleeve 14 and the mounting base 13, and the sealing fit between the first sealing rib 142 and the housing 12, help reduce the risk of leakage of the aerosol generation matrix from the gap between the housing 12 and the mounting base 13.

[0097] The reservoir 112 is able to expose at least part of its surface to the reservoir cavity 12a through the clearance hole, so that the sealing sleeve 14 does not prevent the reservoir 112 from absorbing aerosols to form a matrix.

[0098] Understandably, along the second direction, a portion of the sleeve body 141 and at least a portion of the first sealing rib 142 are located between the open position of the cavity and the atomizing assembly 11.

[0099] In some embodiments, see Figure 9 The number of first sealing ribs 142 is multiple, and the multiple first sealing ribs 142 are arranged along the first direction, which helps to further improve the sealing effect.

[0100] The specific number of the first sealing ribs 142 can be 1, 2, 3, 4, 5, etc.

[0101] In some embodiments, see Figure 4 , Figure 5and Figure 9 The sealing sleeve 14 also includes a limiting beam 144, which spans across the opposite sides of the liquid passage 141a. The limiting beam 144 and the mounting base 13 together form a limiting space, and at least a portion of the atomizing component 11 is located in the limiting space.

[0102] The limiting beam 144 is located inside the liquid storage cavity 12a.

[0103] Thus, the limiting beam 144 can restrict the relative movement between the atomizing component 11 and the mounting hole 13b, thereby helping to maintain the sealing between the atomizing component 11 and the mounting hole 13b.

[0104] The limiting beam 144 is fitted with the atomizing component 11 to reduce the probability of the atomizing component 11 moving relative to the mounting base 13.

[0105] In some embodiments, the limiting beam 144 is positioned across the opposite sides of the liquid passage 141a along the second direction to reduce the risk that the limiting beam 144 and the inner wall of the cavity may fail to limit the atomizing component 11 due to frictional deformation during the insertion of the sealing sleeve 14 into the cavity along the second direction with the mounting base 13.

[0106] In some embodiments, see Figure 3 and Figure 9 The sealing sleeve 14 also includes a second sealing rib 143. The second sealing rib 143 is located on the surface of the sleeve body 141 opposite to the mounting base 13 and is sandwiched between the sleeve body 141 and the housing 12. The second sealing rib 143 is located on the side of the first sealing rib 142 away from the open position of the cavity and is connected to the first sealing rib 142 to jointly enclose and form a lateral sealing area 143a. The liquid passage hole 141a is located on the side of the sleeve body 141 perpendicular to the second direction, and at least a portion of the lateral sealing area 143a is located on the other side.

[0107] Due to the sealing effect of the first sealing rib 142 and the second sealing rib 143, it is difficult for the aerosol generation matrix to flow into the lateral sealing area 143a.

[0108] This helps reduce the amount of aerosol-generating matrix flowing into the narrow gap between the sealing sleeve 14 and the inner wall of the cavity, thereby improving the utilization rate of the aerosol-generating matrix in the storage chamber 12a. At the same time, with the second direction being approximately vertical, the second sealing rib 143 can act as a guide, directing the aerosol-generating matrix towards the liquid passage 141a to contact the storage component 112, thus improving the efficiency of the storage component 112 in absorbing the aerosol-generating matrix.

[0109] The number of second sealing ribs 143 is unlimited; there can be one or more, with multiple second sealing ribs 143 arranged in parallel to each other.

[0110] It is understood that in some embodiments where there are multiple first sealing ribs 142, the second sealing rib 143 is connected to the first sealing rib 142 at the open position furthest from the cavity.

[0111] In some embodiments, the sealing sleeve 14 is an integral structure, that is, the limiting beam 144, the first sealing rib 142, the second sealing rib 143 and the sleeve body 141 are different parts of the same component. This helps to improve the sealing performance, reduce the assembly difficulty and simplify the assembly steps.

[0112] Understandably, the sealing sleeve 14 can undergo elastic deformation to improve the sealing performance.

[0113] The specific material of the sealing sleeve 14 is not limited, such as rubber, silicone, etc.

[0114] In some embodiments, see Figure 3 and Figure 4 The cavity is provided with a mounting post 121, which extends along the second direction. The mounting post 121 is provided with a through discharge channel 12b. A part of the mounting post 121 is inserted into the airflow channel 13a so that the discharge channel 12b communicates with the airflow channel 13a. A part of the sleeve body 141 is sandwiched between the airflow channel 13a and the mounting post 121.

[0115] Thus, by using the sleeve body 141, a seal can be achieved between the mounting column 121 and the mounting base 13, reducing the probability that the aerosol generation matrix will leak from the gap between the mounting column 121 and the mounting base 13 into the discharge channel 12b and the airflow channel 13a.

[0116] This application also provides an aerosol generating device, which includes the atomizer 10 in the aforementioned embodiments. This allows the atomizer 111 to convert the aerosol generating matrix into aerosols under different postures, reducing the risk of dry burning and other problems, and improving the user experience.

[0117] In some embodiments, the aerosol generating apparatus further includes a power supply component electrically connected to the atomizing component 11 to provide electrical energy to the atomizing component 11 so that the atomizing component 11 converts the electrical energy into heat energy.

[0118] The various embodiments / implementations of this utility model can be combined with each other without creating contradictions.

For those skilled in the art, various modifications and variations can be made to the embodiments of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the embodiments of this utility model should be included within the protection scope of this utility model.
