Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to an atomizer, a liquid storage component, and an aerosol generation device including the atomizer. Background Technology

[0002] An atomizer is a device capable of storing and atomizing a liquid matrix. As an example, the prior art includes an atomizer comprising a liquid storage assembly for storing a liquid matrix and an atomizing assembly containing an atomizing core. The liquid storage assembly has a guide tube with an inlet hole on its side wall, and the atomizing assembly includes a retaining tube with an outlet hole on its side wall. The atomizing core is retained in the retaining tube corresponding to the outlet hole. When the atomizing assembly is connected to the liquid storage assembly, the guide tube and the retaining tube are arranged along the same central axis, and the inlet hole and the outlet hole are connected, thereby delivering the liquid matrix in the liquid storage assembly to the atomizing assembly.

[0003] However, when the atomizer is tilted during inhalation, the inlet hole may not be fully submerged in the liquid matrix, resulting in a lack of liquid matrix supplied to the atomizer core, or even local overheating and dry burning of the atomizer core. Utility Model Content

[0004] The purpose of this application is to provide an atomizer, a liquid storage assembly, and an aerosol generating device including the atomizer, which helps to prevent a reduction in the atomization efficiency of the atomizer core.

[0005] At least one embodiment of this application provides an atomizer, the atomizer comprising:

[0006] An atomizing assembly includes an atomizing core for atomizing a liquid matrix to generate an aerosol and a holding assembly for holding the atomizing core, the holding assembly having an inlet hole communicating with the atomizing core; and

[0007] A liquid storage assembly includes a piston, a housing having an internal storage cavity, and an outlet port for discharging a liquid matrix stored in the storage cavity. The piston is configured to be movable from a first position to a second position and to seal the outlet port when in the first position.

[0008] Wherein, when the atomizing component is connected to the liquid storage component, a buffer space is constructed between the two. The atomizing component is configured to move relative to the liquid storage component, thereby driving the piston to move to the second position to open the outlet hole. The buffer space is used to connect the outlet hole and the inlet hole, so that when the outlet hole is open, the buffer space can store part of the liquid matrix to supply to the atomizing core.

[0009] As an example, when the piston is in the second position, the atomizing assembly satisfies at least one of the following conditions:

[0010] The inlet hole is located outside the storage cavity;

[0011] At least a portion of the atomizing core is located outside the storage cavity; and

[0012] The buffer space extends at least partially away from the piston outside the storage cavity.

[0013] As an example, the retaining assembly includes a retaining tube, at least partially retaining the atomizing core inside the retaining tube, and the inlet hole is formed on the side wall of the retaining tube corresponding to the atomizing core;

[0014] The liquid storage assembly includes a guide tube at least partially located in the storage cavity, the piston is movably disposed in the guide tube, and the outlet hole is formed on the side wall of the guide tube;

[0015] When the atomizing component is connected to the liquid storage component, at least a portion of the holding tube is located inside the guide tube, and the buffer space is defined between the guide tube and the holding tube.

[0016] As an example, the retaining tube abuts against the piston, and the piston is used to provide a seal between the guide tube and the retaining tube.

[0017] As an example, a first seal is also included, which connects the guide tube and the retaining tube and provides a seal between the guide tube and the retaining tube when the piston is in the second position, and the buffer space is located between the first seal and the piston.

[0018] As an example, the storage cavity has a proximal end and a distal end disposed opposite to each other, the liquid storage assembly further includes a sealing seat that provides a seal between the housing and the guide tube, the storage cavity being located between the housing and the sealing seat, the surface of the sealing seat disposed toward the proximal end defining the boundary of the distal end; the outlet port is disposed adjacent to the distal end.

[0019] As an example, the liquid reservoir assembly further includes a backstop and a discharge channel for discharging aerosol from the atomizer, the discharge channel passing through the piston, the backstop being located on the side of the piston away from the atomizing assembly to prevent the piston from moving out of the guide tube in a direction away from the atomizing assembly.

[0020] As an example, the reservoir assembly also includes a support tube retained inside the piston, the support tube providing force to maintain a sealed connection between the piston and the inner wall of the guide tube, and the support tube defining at least a portion of the boundary of the outlet channel.

[0021] As an example, at least a portion of the guide tube extends longitudinally within the storage cavity, and the liquid storage assembly further includes a venting passage communicating with the air inlet passage and the storage cavity, and a sealing seat providing a seal between the housing and the guide tube, the storage cavity being formed between the housing and the sealing seat, and the sealing seat defining at least a portion of the boundary of the venting passage.

[0022] The retaining assembly also includes a base for supporting the retaining tube, the base defining at least a portion of the boundary of the air intake passage.

[0023] As an example, the ventilation channel includes an air guide groove disposed between the housing and the sealing seat and communicating with the storage cavity, a through hole formed on the sealing seat and communicating with the air inlet channel, and a curved channel disposed between the housing and the sealing seat. The air guide groove and the through hole are offset in the circumferential direction and are connected through the curved channel.

[0024] As an example, the liquid storage assembly also includes a porous element disposed in the storage cavity, wherein a portion of the liquid matrix in the storage cavity remains in a free-flowing state, while a portion of the liquid matrix is ​​adsorbed by the porous element.

[0025] As an example, the liquid storage assembly includes a guide tube at least partially located in the storage cavity, the piston is movably disposed in the guide tube, and the outlet hole is located in the storage cavity and formed on the side wall of the guide tube;

[0026] The liquid storage assembly further includes a sealing seat that provides a seal between the housing and the guide tube, and the storage cavity is formed between the housing and the sealing seat;

[0027] The porous element is positioned at intervals between the outlet holes or between the guide tubes.

[0028] As an example, the sealing seat or between the sealing seat and the housing has an annular groove facing the storage cavity, and the porous element includes a porous ring disposed in the annular groove.

[0029] As an example, the thickness of the porous element is between 0.5 mm and 2.5 mm; and / or

[0030] The volume of the porous element is between 50 mm. 3 -300mm 3 ; and / or

[0031] The volume of the porous element is less than 1 / 10 of the volume of the storage cavity.

[0032] As an example, the liquid storage component is provided with a foolproof structure, and the atomizing component is provided with a foolproof mating structure, so that after the atomizing component and the liquid storage component are connected, the buffer space is set to correspond to the outlet hole.

[0033] As an example, the reservoir assembly has a pre-installed position and a working position for selective connection of the atomizing assembly, wherein when the atomizing assembly is connected to the pre-installed position, the piston remains in the first position, and when the atomizing assembly is connected to the working position, the piston is in the second position.

[0034] At least one embodiment of this application provides a liquid storage assembly, which includes a guide tube, a porous element, a housing, and a sealing seat connected to the housing. The housing and the sealing seat have a storage cavity for storing a liquid matrix. At least a portion of the guide tube is located in the storage cavity, and the sidewall of the guide tube has an outlet hole for discharging the liquid matrix stored in the storage cavity.

[0035] In this configuration, a portion of the liquid matrix remains in a free-flowing state within the storage cavity, while a portion of the liquid matrix is ​​adsorbed by the porous element, and the porous element is positioned at intervals between the outlet hole and the guide tube.

[0036] At least one embodiment of this application provides an aerosol generating apparatus, wherein the atomizer of the aerosol generating apparatus further includes a power supply for providing electrical power to the atomizing component so that the atomizing core atomizes a liquid matrix.

[0037] In the atomizer and aerosol generating apparatus including the atomizer provided in the above embodiments, the atomizer includes a liquid storage component and an atomizing component. The liquid storage component has a liquid reservoir for storing a liquid matrix and an outlet port for discharging the liquid matrix. The atomizing component includes an inlet port for guiding the liquid matrix to the atomizing core and an atomizing core for atomizing the liquid matrix to generate an aerosol. The atomizing component is configured to move relative to the liquid storage component, thereby driving a piston to move to a second position to open the outlet port. A buffer space between the atomizing component and the liquid storage component connects the outlet port and the inlet port, so that when the outlet port is open, the buffer space can store a portion of the liquid matrix to supply to the atomizing core. Therefore, the liquid storage component and the atomizing component can not only be stored separately, but also, when the atomizer is tilted due to use, the liquid matrix stored in the buffer space can continue to submerge the inlet port, thereby preventing the loss of liquid matrix supplied to the atomizing core and thus preventing a decrease in the atomization efficiency of the atomizing core.

[0056] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0057] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be intervening elements. When an element is referred to as being "connected to" another element, it can be directly connected to the other element, or there may be one or more intervening elements. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0058] Please refer to Figure 1 This application provides an aerosol generating device 100, which includes an atomizer 2 and a power supply 1. The power supply 1 can be used in conjunction with the atomizer 2 and can provide electrical power to the atomizer 2, which is held in a suitable position, so that the atomizer 2 atomizes the aerosol generating matrix to generate aerosol.

[0059] In some embodiments, the aerosol-generating matrix includes a liquid matrix that is liquid at room temperature. The liquid matrix may contain a liquid containing tobacco-containing substances with volatile tobacco aroma components. The liquid matrix may also contain a liquid containing non-tobacco substances. The liquid matrix may contain water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include, but are not limited to, areca nut extract, menthol, peppermint, spearmint oil, various fruit flavoring components, etc. Flavorings may contain ingredients that can provide the user with various aromas or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these.

[0060] In some embodiments, the aerosol-generating matrix includes a solid matrix that is solid at room temperature. The solid matrix may comprise a solid containing tobacco-containing substances, including volatile tobacco aroma components. The solid matrix may also comprise a solid containing non-tobacco substances.

[0061] In other embodiments, the aerosol generating matrix also includes a paste-like matrix that is in the form of a paste at room temperature.

[0062] In some embodiments, reference may be made to Figure 3 and Figure 7 The atomizer 2 includes an atomizing component 21 for atomizing the aerosol generating matrix to generate an aerosol. Specifically, the atomizing component 21 includes an atomizing core 211.

[0063] When the aerosol generating matrix includes a liquid matrix, the atomizing core 211 may include a liquid-absorbing element 2112 and a heating element 2111, with the heating element 2111 disposed on the liquid-absorbing element 2112. The liquid-absorbing element 2112 may be a porous body, used to guide the liquid matrix into the atomization range of the heating element 2111. The heating element 2111 is used to heat and atomize the liquid matrix, thereby generating an aerosol. The porous body may include fibers, such as cotton fibers, polypropylene fibers, polyester fibers, or nylon fibers. The porous body may also include porous ceramics or porous metals; this application does not limit the structure and composition of the porous body.

[0064] Of course, the atomizing core 211 may also include an ultrasonic element capable of generating ultrasonic waves, which enables the atomizing core 211 to atomize the liquid matrix into an aerosol using ultrasonic waves. The atomizing core 211 may also include other elements capable of atomizing the liquid matrix into an aerosol.

[0065] When the aerosol generating matrix includes a solid matrix, the atomizing core 211 includes a heating element for heating the fixed matrix. The heating element releases heat to cause the solid matrix to produce volatile substances, thereby generating an aerosol. This heating element for heating the fixed matrix may include at least one of an external heating element, an internal heating element, and an air heating element. As used herein, an "external heating element" refers to a heating element that provides heat or radiates infrared radiation from the outside of the solid matrix to heat the fixed matrix. An "internal heating element" refers to a heating element that provides heat or radiates infrared radiation from the inside of the solid matrix to heat the fixed matrix. An "air heating element" refers to a heating element disposed upstream of the fixed matrix along the airflow direction for heating air, which then flows into the fixed matrix to heat the solid matrix.

[0066] In some embodiments, the atomizing assembly 21 has a longitudinally extending atomizing cavity 213, allowing airflow to flow longitudinally within the atomizing cavity 213. The aerosol generated by the atomizing aerosol generation matrix of the atomizing core 211 is primarily formed within the atomizing cavity 213.

[0067] In some embodiments, reference may be made to Figures 2-5 The atomizer 2 includes a liquid storage assembly 22. The liquid storage assembly 22 includes a housing 221, and the housing 221 has a storage cavity 222 for storing a liquid matrix. When the atomizing assembly 21 is connected to the liquid storage assembly 22 in the appropriate position, the atomizing core 211 communicates with the storage cavity 222, so that the atomizing core 211 can atomize the liquid matrix contained in the storage cavity 222.

[0068] In some embodiments, reference may be made to Figures 3-5The liquid storage assembly 22 also includes a piston 224 and an outlet port 2231 for discharging the liquid matrix stored in the storage chamber 222. The piston 224 is movable between a first position and a second position, and when the piston 224 is in the first position (see reference...), Figure 3 and Figure 4 Piston 224 seals outlet port 2231. When outlet port 2231 is sealed, the liquid matrix is ​​sealed in storage chamber 222, thus allowing the liquid storage assembly 22 and atomizing assembly 21 to be stored separately when outlet port 2231 is sealed. When piston 224 is in the second position (see reference...), Figure 5 The outlet hole 2231 is opened, thereby enabling the liquid matrix stored in the storage cavity 222 to be exported.

[0069] The atomizing component 21 can be connected to the liquid storage component 22, and when the two are connected, there is a buffer space 23 between the components of the atomizing component 21 and the liquid storage component 22. The atomizing component 21 also includes a holding component 212 for holding the atomizing core 211. The holding component 212 has an inlet hole 212a. After the atomizing component 21 is connected to the liquid storage component 22 at an appropriate position, the inlet hole 212a communicates with the outlet hole 2231, and the inlet hole 212a can guide the liquid matrix out of the liquid storage component 21 to the atomizing core 211, so that the liquid matrix is ​​atomized by the atomizing core 211 to generate an aerosol.

[0070] The atomizing component 21 is configured to drive the piston 224 to a second position, opening the outlet port 2231, during movement when connected to the liquid reservoir component 22 at an appropriate position. The buffer space 23 is configured to connect the outlet port 2231 and the inlet port 212a when the piston 224 is in the second position, allowing the buffer space 23 to store a portion of the liquid matrix for supply to the atomizing coil 211 when the outlet port 2231 is open. Therefore, when the atomizer 2 is tilted, the liquid matrix stored in the buffer space 23 can continue to submerge the inlet port 212a, thus preventing a decrease in the atomization efficiency of the atomizing coil 211.

[0071] In some embodiments, reference may be made to Figure 4 and Figure 5 The liquid storage assembly 22 has a pre-installed position and a working position for selective connection of the atomizing assembly 21. When the atomizing assembly 21 is connected in the pre-installed position, the piston 224 remains in the first position, thereby keeping the storage chamber 222 sealed. When the atomizing assembly 21 is connected in the working position, the piston 224 is in the second position, thereby opening the outlet port 2231 and connecting the buffer space 23 and the storage chamber 222. A portion of the liquid matrix in the storage chamber 222 can flow into the buffer space 23 through the outlet port 2231 for storage, and then flow to the atomizing core 211 through the inlet port 212a.

[0072] Therefore, the atomizing component 21 can be connected to the pre-installed position of the liquid storage component 22, so that the atomizing component 21 and the liquid storage component 22 can be stored together as a whole. Since the outlet hole 2231 is sealed by the piston 224 located in the first position, when the atomizing component 21 is connected to the pre-installed position and stored together with the liquid storage component 22, leakage of the liquid matrix in the storage chamber 222 and flow of the liquid matrix in the storage chamber 222 to the atomizing core 211 can be effectively prevented.

[0073] When the atomizer 2 is needed, the atomizing component 21 can be driven to move to the working position on the liquid storage component 22, so that the liquid matrix in the storage chamber 222 can flow to the atomizing core 211, and the atomizer 2 can generate aerosol.

[0074] In some embodiments, during the process of connecting the atomizing component 21 to the appropriate position of the liquid storage component 22, the atomizing component 21 mainly drives the piston 224 from the first position to the second position by the retaining component 212 acting on the piston 224. Specifically, when the atomizing component 21 is connected to the pre-installed position, the retaining component 212 may contact the piston 224 or be spaced apart from the piston 224. During the process of the atomizing component 21 moving from the pre-installed position to the working position, the retaining component 212 can push the piston 224 from the first position to the second position.

[0075] In some embodiments, reference may be made to Figure 2 and Figure 3 The retaining assembly 212 includes a retaining tube 2121, with at least a portion of the atomizing core 211 retained inside the retaining tube 2121, and an inlet hole 212a corresponding to the atomizing core 211 is formed on the side wall of the retaining tube 2121. The liquid storage assembly 22 includes a guide tube 223 at least partially located in the storage cavity 222, and a piston 224 is movably disposed in the guide tube 223, so that the piston 224 can move along the inner wall of the guide tube 223 between a first position and a second position. An outlet hole 2231 is located in the storage cavity 222 and is formed on the side wall of the guide tube 223.

[0076] When the atomizing component 21 is connected to the liquid storage component 22, at least a portion of the holding tube 2121 is located inside the guide tube 223, and the buffer space 23 is located between the guide tube 223 and the holding tube 2121, with the holding tube 2121 and the guide tube 223 respectively defining a portion of the boundary of the buffer space 23.

[0077] Furthermore, the outer diameter of the retaining tube 2121 is smaller than the inner diameter of the guide tube 223, thereby reducing the frictional resistance between the retaining tube 2121 and the guide tube 223 during the process of at least partially assembling the retaining tube 2121 into the guide tube 223.

[0078] In some embodiments, the radial distance between the guide tube 223 and the holding tube 2121, or the difference in the inner radii of the guide tube 223 and the holding tube 2121, is defined as D, and D satisfies the condition: 0.1mm ≤ D ≤ 1.2mm. Preferably, 0.5mm ≤ D ≤ 0.8mm, for example, D can be approximately 0.625mm, so that the buffer space 23 has an appropriate width. Thus, the buffer space 23 can lock the liquid matrix introduced therein, thereby preventing the liquid matrix in the buffer space 23 from flowing back into the storage chamber 222 when the atomizer 2 is tilted, so that the inlet port 212a continues to be immersed in the liquid matrix. At the same time, the buffer space 23 can store a relatively large amount of liquid matrix, so that the liquid matrix stored in the buffer space 23 can meet the user's inhalation needs for at least one puff, so that the inlet port 212a can always be immersed in the liquid matrix in the buffer space 23 while the atomizer 2 is tilted due to inhalation.

[0079] In some embodiments, the radius or equivalent radius of the outlet hole 2231 is defined as d, and satisfies the condition d ≤ D. When the outlet hole 2231 is a circular hole with a regular shape, d is the radius of the outlet hole 2231; when the outlet hole 2231 is an irregularly shaped hole, d can be the equivalent radius of the outlet hole 2231, such as an elliptical shape; or d is defined as the minimum distance between the center of the outlet hole 2231 and the edge of the outlet hole 2231. As an example, when the outlet hole 2231 is a circular hole and the radius d of the outlet hole 2231 is 0.5 mm, then D ≥ 0.5 mm. Or, for example, when D is 0.625 mm, then the radius d of the outlet hole 2231 ≤ 0.625 mm.

[0080] When the atomizing assembly 21 is connected in the pre-installed position, a portion of the retaining tube 2121 may be located within the guide tube 223. When the atomizing assembly 21 is connected in the working position, the retaining tube 2121 may extend further into the guide tube 223.

[0081] Preferably, when the atomizing assembly 21 is connected to the liquid storage assembly 22 at an appropriate position, the guide tube 223 and the retaining tube 2121 are arranged along the same central axis. More preferably, both the guide tube 223 and the retaining tube 2121 extend longitudinally.

[0082] In some embodiments, reference may be made to Figure 5 When the atomizing assembly 21 is connected to the liquid storage assembly 22 in the appropriate position, the retaining tube 2121 abuts against the piston 224, and the piston 224 provides a seal between the guide tube 223 and the retaining tube 2121.

[0083] For example, the retaining tube 2121 has a first end and a second end arranged opposite to each other, and the atomizing core 211 can be disposed between the first end and the second end. When the atomizing assembly 21 is connected in the pre-installed position, it can be referred to... Figure 4 The first end contacts or abuts against the piston 224. When the atomizing assembly 21 is connected in the working position, refer to... Figure 5 The first end abuts against the piston 224, thereby maintaining a sealed connection between the retaining tube 2121 and the piston 224. This prevents the liquid matrix from flowing into the retaining tube 2121 from between the piston 224 and the first end, and also prevents aerosol from flowing into the buffer space 23 from between the piston 224 and the first end. Simultaneously, regardless of whether the piston 224 is in the first or second position, the piston 224 is in a sealed abutment against the inner wall of the guide tube 223. When the piston 224 is in the first position, it prevents the liquid matrix from leaking into the guide tube 223 through the outlet hole 2231. When the piston 224 is in the second position, it defines a portion of the boundary of the buffer space 23 and prevents fluid from leaking out of the buffer space 23 from between the piston 224 and the inner wall of the guide tube 223.

[0084] In some embodiments, reference may be made to Figure 4 and Figure 5 The atomizer 2 also includes a first seal 2122, which can be disposed on the retaining tube 2121 or the guide tube 223. When the piston 224 is in the second position or when the atomizing assembly 21 is connected to the liquid storage assembly 21 in the working position, the first seal 2122 connects the guide tube 223 and the retaining tube 2121, providing a seal between them. The buffer space 23 and the inlet port 212a are both located between the first seal 2122 and the piston 224. Furthermore, the first seal 2122 can define a portion of the boundary of the buffer space 23. The buffer space 23 can be located between the first seal 2122 and the piston 224.

[0085] For example, a first seal 2122 is disposed on the retaining tube 2121. When the atomizing assembly 21 drives the piston 224 to move from the first position to the second position, or when the atomizing assembly 21 is connected in the working position, at least a portion of the retaining tube 2121 moves longitudinally within the guide tube 223. At least a portion of the first seal 2122 follows the retaining tube 2121 into the guide tube 223 and is laterally clamped between the guide tube 223 and the retaining tube 2121, thereby providing a seal between the guide tube 223 and the retaining tube 2121. Preferably, the first seal 2122 is made of silicone.

[0086] When the atomizing component 21 is connected to the pre-installed position, you can refer to Figure 4A portion of the first seal 2122 may also be located within the guide tube 223, thereby being positioned laterally between the guide tube 223 and the retaining tube 2121, in which case the first seal 2122 can provide a seal between the guide tube 223 and the retaining tube 2121. Of course, when the atomizing assembly 21 is connected in the pre-installed position, the first seal 2122 may also have a clearance fit with either the guide tube 223 or the retaining tube 2121.

[0087] Preferably, the first seal 2122 is disposed adjacent to the second end of the retaining tube 2121. Thus, when the atomizing assembly 21 is connected to the liquid storage assembly 22, the first seal 2122 and the piston 224 are disposed opposite to each other.

[0088] In some embodiments, reference may be made to Figure 4 The storage cavity 222 has a proximal end 2221 and a distal end 2222 disposed opposite to each other. The liquid storage assembly 22 also includes a sealing seat 225 that provides a seal between the housing 221 and the guide tube 223. The storage cavity 222 is located between the housing 221 and the sealing seat 225. The surface of the sealing seat 225 facing the proximal end 2221 of the storage cavity 222 defines the boundary of the distal end 2222 of the storage cavity 222. The outlet hole 2231 is disposed adjacent to the distal end of the storage cavity 222, which helps to allow as much of the liquid matrix stored in the storage cavity 222 as possible to be discharged through the outlet hole 2231, thereby improving the utilization rate of the liquid matrix and reducing waste due to the inability to discharge the liquid matrix.

[0089] In some embodiments, reference may be made to Figure 5 When the piston 224 is in the second position or when the atomizing assembly 21 is connected to the working position, the outlet hole 2231 is located longitudinally between the inlet hole 212a and the piston 224, so that the central axis of the inlet hole 212a and the central axis of the outlet hole 2231 do not coincide and have a longitudinal drop. At the same time, at least a portion of the buffer space 23 can extend away from the piston 224 to the outside of the storage cavity 222. That is, when the piston 224 is in the second position or when the atomizing assembly 21 is connected to the working position, at least a portion of the buffer space 23 and the outlet hole 2231 are located on opposite sides of the distal end 2222 of the storage cavity 222. Thus, at least a portion of the buffer space 23 is located below the storage cavity 222. When the outlet hole 2231 is open, the liquid matrix in the storage cavity 222 can automatically flow into the buffer space 23 and into the inlet hole 212a through the outlet hole 2231 under the action of gravity, which is beneficial for the buffer space 23 to store the liquid matrix.

[0090] In some embodiments, reference may be made to Figure 5When the piston 224 is in the second position or when the atomizing assembly 21 is connected to the working position, the inlet hole 212a is located outside the storage cavity 222. That is, when the piston 224 is in the second position or when the atomizing assembly 21 is connected to the working position, the inlet hole 212a and the outlet hole 2231 are located on opposite sides of the distal end 2222 of the storage cavity 222.

[0091] This ensures that the inlet hole 212a and at least part of the buffer space 23 are located below the storage cavity 222 in the direction of gravity. Therefore, when the atomizer 2 is tilted, as long as the storage cavity 222 contains liquid matrix, the inlet hole 212a can be submerged by the liquid matrix with a high probability.

[0092] Furthermore, when the piston 224 is in the second position or when the atomizing assembly 21 is connected in the working position, the inlet hole 212a is located longitudinally between the first seal 2122 and the distal end 2222 of the storage cavity 222.

[0093] In some embodiments, reference may be made to Figure 5 When the piston 224 is in the second position or when the atomizing assembly 21 is connected to the working position, while the outlet hole 2231 is located longitudinally between the inlet hole 212a and the piston 224, at least a portion of the atomizing core 211 is located outside the storage cavity 222. That is, when the piston 224 is in the second position or when the atomizing assembly 21 is connected to the working position, at least a portion of the atomizing core 211 and the outlet hole 2231 are located on opposite sides of the distal end 2222 of the storage cavity 222. Further, the inlet hole 212a is provided corresponding to the middle region of the atomizing core 211 in the longitudinal direction.

[0094] In some embodiments, the liquid storage assembly 22 further includes a retaining portion 226 and an outlet channel 227 for discharging aerosol from the atomizer 2. The outlet channel 227 passes through the piston 224, and the retaining portion 226 is located on the side of the piston 224 away from the atomizing assembly 21 to prevent the piston 224 from moving out in the direction away from the atomizing assembly 21.

[0095] Furthermore, the housing 221 has an air outlet 2211 through which the aerosol is discharged from the atomizer 2. A discharge channel 227 connects to the air outlet 2211 and is located upstream of the air outlet 2211 along the airflow direction. Further still, the housing 221 includes a top wall 2212 adjacent to the proximal end 2221 of the storage cavity 222 and a side wall 2213 connecting the top wall 2212 and surrounding the storage cavity 2222. A retaining portion 226 extends from the top wall 2212 toward the distal end 2222 of the storage cavity 222, and at least partially fits into the guide tube 223. The discharge channel 227 passes through the retaining portion 226 and defines a portion of the boundary of the discharge channel 227. Along the airflow direction, the discharge channel 227 inside the piston 224 is located upstream of the discharge channel 227 inside the retaining portion 226.

[0096] Furthermore, one can refer to Figure 1 The aerosol generating device 100 also includes a mouthpiece 3 with an air intake 31. The mouthpiece 3 can be held in the lips by a user, and when the user holds the mouthpiece 3, the air intake 31 faces the user's mouth. The mouthpiece 3 is connected to the housing 221, and the air outlet 2211 of the housing 221 communicates with the air intake 31. In some embodiments, the atomizer 2 includes the mouthpiece 3. Further, the mouthpiece 3 is integrally formed with the housing 221, so that the air intake 31 and the air outlet 2211 coincide.

[0097] In some embodiments, reference may be made to Figure 4 and Figure 8 The reservoir assembly 22 also includes a support tube 228 held inside the piston 224, the support tube 228 providing force to maintain a sealed connection between the piston 224 and the inner wall of the guide tube 223, and the support tube 228 defining at least a portion of the boundary of the outlet channel 227.

[0098] The piston 224 is elastic and has relatively low hardness. A support tube 228 is provided inside the piston 224. The support tube 228 can support the piston 224, so that the piston 224 and the inner wall of the guide tube 223 are sealed and abutted. At the same time, it can also ensure that the outlet channel 227 inside the piston 224 has a large flow area, so as to avoid the piston 224 contracting inward under the inward compression of the inner wall of the guide tube 223, which would close the internal channel of the piston 224 and thus block the outlet channel 227.

[0099] Preferably, the support tube 228 is a metal tube, so the support tube 228 has a thinner tube wall and greater hardness.

[0100] In some embodiments, the piston 224 is configured to move only unidirectionally from the first position to the second position, such that after the piston 224 is driven to the second position, if the atomizing component 21 is then removed from the liquid storage component 22, the piston 224 remains in the second position.

[0101] In such Figure 3 and Figure 4 In the illustrated embodiment, the stop portion 226 includes a base 2261 and an extension 2262. The base 2261 connects the extension 2262 and the top wall 2212. The wall thickness of the extension 2262 is less than the wall thickness of the base 2261, thereby forming a shoulder between the extension 2262 and the shoulder 2261. The extension 2262 is located in the guide tube 223, and a receiving space 229 is formed between the extension 2262 and the inner wall of the guide tube 223. The shoulder defines a portion of the boundary of the receiving space 229. The piston 224 includes a first portion 2241 disposed toward the top wall 2212 and a second portion 2242 for receiving the support tube 228. When the piston 224 is in a first position, at least a portion of the first portion 2241 is located outside the receiving space 229, and the first portion 2241 is longitudinally spaced from the shoulder. When the piston 224 is in the second position, at least a portion of the first part 2241 is located in the receiving space 229 and is held by the extension 2262 and the guide tube 223, and the first part 2241 can abut against the shoulder, and / or one end of the extension 2262 away from the base 2261 can abut against the ridge on the piston 224 located between the first part 2241 and the second part 2242.

[0102] In some embodiments, the storage chamber 222 is configured to be under negative pressure before the piston 224 moves from the first position to the second position, for example, the internal pressure of the storage chamber 222 is lower than one standard atmosphere, so as to prevent leakage of the liquid matrix in the storage chamber 222 when the liquid storage assembly 22 is stored separately.

[0103] Furthermore, you can refer to Figure 4 and Figure 8 The liquid storage assembly 22 also includes a porous element 230 disposed in the storage cavity 222. The porous element 230 may include fibers, such as cotton fibers, polypropylene fibers, polyester fibers, or nylon fibers. The porous element 230 may also include porous ceramics or porous metals. The porous element 230 is capable of adsorbing liquid matrix, thereby locking in the liquid matrix.

[0104] In the storage chamber 222, part of the liquid matrix remains in a free-flowing state, while the rest is adsorbed by the porous element 230, thus becoming non-free-flowing. After injecting the liquid matrix into the storage chamber 222, the porous element 230 and the sealing seat 225 can be assembled. Then, the storage chamber 222 can be shaken or inverted, causing part of the liquid matrix in the storage chamber 222 to be adsorbed by the porous element 230, thereby reducing the air pressure in the storage chamber 222 and creating a negative pressure state.

[0105] In some embodiments, reference may be made to Figures 3-5 The sealing seat 225 or between the sealing seat 225 and the housing 221 has an annular groove facing the storage cavity 222. The porous element 230 includes a porous ring disposed in the annular groove, thereby holding the porous ring on the sealing seat 225 or between the sealing seat 225 and the housing 221 to prevent the porous ring from moving in the storage cavity 222.

[0106] In some embodiments, the porous element 230 is provided with spaced outlet holes 2231 or spaced guide tubes 223 to reduce the resistance of the freely flowing liquid matrix in the storage cavity 222 into the outlet holes 2231, and to prevent the liquid matrix adsorbed by the porous element 230 from being conducted to the atomizing core 211 through the outlet holes 2231. Therefore, the amount of liquid matrix adsorbed by the porous element 230 should not be excessive, thereby reducing liquid matrix waste and improving the utilization rate of the liquid matrix.

[0107] In some embodiments, the porous element 230 is used to adsorb a portion of the liquid matrix to appropriately reduce the gas pressure inside the storage cavity 222, thereby improving the utilization rate of the liquid matrix in the storage cavity 222.

[0108] The thickness of the porous element 230 is between 0.5 mm and 2.5 mm, for example, the thickness of the porous element 230 can be approximately 1.8 mm; and / or, the volume of the porous element 230 is between 50 mm². 3 -300mm 3 For example, the volume of the porous element 230 can be approximately 250 mm. 3 ; and / or, the volume of the porous element 230 is less than 1 / 10 of the volume of the storage cavity 222, preferably, the volume of the porous element 230 is less than 1 / 20 of the volume of the storage cavity 222, for example, the volume of the porous element 230 can be about 1 / 40 of the volume of the storage cavity 222.

[0109] It should be noted that in other embodiments, after injecting a liquid matrix into the storage cavity 222, some of the gas in the storage cavity 222 can be extracted, thereby making the storage cavity 222 a negative pressure state.

[0110] In some embodiments, the liquid storage assembly 22 further includes a ventilation channel 22a, and a sealing seat 225 defines at least a portion of the boundary of the ventilation channel 22a. The holding assembly 212 further includes a base 2123 supporting the holding tube 2121, the base 2123 defining at least a portion of the boundary of the air intake channel 214, through which external air enters the atomizer 2. The ventilation channel 22a connects the air intake channel 214 and the storage chamber 222, thereby balancing the air pressure between the storage chamber 222 and the outside air after the outlet port 2231 is opened, so that the liquid matrix in the storage chamber 222 can be smoothly guided from the outlet port 2231 to the buffer space 23.

[0111] The ventilation passage 22a can be completely formed on the sealing seat 225. At least a portion of the ventilation passage 22a can be disposed between the sealing seat 225 and the housing 221. At least a portion of the ventilation passage 22a can be disposed between the sealing seat 225 and the guide tube 223.

[0112] In such Figure 3 and Figure 8 In the illustrated embodiment, the ventilation channel 22a includes a guide groove 22a1 disposed between the housing 221 and the sealing seat 225 and communicating with the storage cavity, a through hole 22a2 formed on the sealing seat 225 and communicating with the air inlet channel 214, and a curved channel 22a3 disposed between the housing 221 and the sealing seat 225. The guide groove 22a1 and the through hole 22a2 are circumferentially offset and are connected by the curved channel 22a3. This extends the length of the ventilation channel 22a, thereby extending the time the storage cavity 222 is in a negative pressure state when the outlet hole 2231 is sealed by the piston 224. Preferably, the guide groove 22a1 and the through hole 22a2 are arranged opposite to each other. There may be two curved channels 22a3, and the two curved channels 22a3 can be combined to form an annular shape.

[0113] Furthermore, the porous element 230 defines a portion of the boundary of the curved channel 22a3, thereby enabling the porous element 230 to absorb the liquid matrix in the curved channel 22a3, which helps prevent the liquid matrix from leaking through the ventilation channel 22a.

[0114] In some embodiments, reference may be made to Figure 6 The atomizing component 21 also includes a first electrode 215 and a second electrode 216 for electrical connection with the power supply 1. The atomizing core 211 also includes a first pin 2113 and a second pin 2114. The first electrode 215 and the second electrode 216 are held on the base 2123, and the first electrode 215 and the second electrode 216 abut against the first pin 2113 and the second pin 2114 in a one-to-one correspondence.

[0115] The base 2123 may have a mounting hole 212b and a through hole 212c. The end of the first pin 2113 passes through the through hole 212c and exits the base 2123, then folds back and is located in the mounting hole 212b. The first electrode 215 is held in the mounting hole 212b, thereby abutting against the end of the first pin 2113 to achieve electrical connection between the first electrode 215 and the first pin 2113. Similarly, the second electrode 216 is electrically connected to the second pin 2114.

[0116] In some embodiments, the sealing seat 225 includes a second seal 2251 and a support 2252, the second seal 2251 providing a seal between the support 2252 and the housing 221, and a seal between the support 2252 and the guide tube 223. Further, the second seal 2251 defines a portion of the boundary of the curved channel 22a3. The second seal 2251 may also define a portion of the boundary of the annular groove, and at least a portion of the porous element 230 may be disposed between the housing 221 and the second seal 2251, such that at least a portion of the curved channel 22a3 may be disposed between the porous element 230 and the second seal 2251.

[0117] In some embodiments, the support 2252 includes a first support 225a, a second support 225b, and a support wall 225c connecting the first support 225a and the second support 225b. A second seal 2251 is held on the first support 225a. The first support 225a and the support wall 225c are located inside the housing 221. The second support 225b extends laterally and is located outside the housing 221 to support the housing 221 longitudinally. When assembling the liquid storage assembly 22, a porous element 230 can be disposed on the seal 225, and then the seal 225 is partially installed inside the housing 221 by operating the support 2252, thereby forming a storage cavity 222 between the seal 225 and the housing 221. The second support 225b is stopped by the end of the housing 221 to prevent the seal 225 from extending further into the housing 221. The seal 225 and the housing 221 can be riveted together.

[0118] In such Figure 3 In the illustrated embodiment, the guide tube 223 passes through the sealing seat 225, and a portion of the guide tube 223 is located in the storage cavity 222, while a portion of the guide tube 223 extends away from the proximal end 2221 of the storage cavity 222 and is surrounded by the support wall 225c.

[0119] When the atomizing component 21 is connected to the working position of the liquid storage component 22, or when the piston 224 is in the second position, the base 2123 can be snapped into connection with the support 2252.

[0120] In some embodiments, a leak-proof groove 225e is provided between the first support 225a and the second seal 2251. The leak-proof groove 225e may be arranged around the guide tube 223 and communicates with the through hole 22a2, so that the leak-proof groove 225e can store the liquid matrix leaked through the ventilation channel 22a.

[0121] The through hole 22a2 may include a first through hole 22a21 opened on the support 2252 and a second through hole 22a22 opened on the second seal 2251 and a guide groove 22a23. The second through hole 22a22 is opened toward the porous element 230 and the second through hole 22a22 connects the guide groove 22a23 and the first through hole 22a21. The guide groove 22a23 connects to 22a3.

[0122] In some embodiments, the atomizer 2 further includes a third seal 218, which may be disposed on the base 2123 of the atomizing assembly 21 or on the support 2252 of the liquid storage assembly. When the atomizing assembly 21 is connected to the liquid storage assembly 22 in the appropriate position, such as when the atomizing assembly 21 is connected to the working position, the third seal 218 provides a seal between the support 2252 and the base 2123. The first seal 2122, the second seal 2251, and the third seal 218 may all be made of silicone.

[0123] In some embodiments, reference may be made to Figure 2 and Figure 7 The liquid storage component 22 is provided with a foolproof structure, and the atomizing component 21 is provided with a foolproof mating structure 217, so that the atomizing component 21 and the liquid storage component 22 can only be connected in a preset direction. After the two are connected, the buffer space 23 is set with the corresponding outlet hole 2231.

[0124] Furthermore, the support 2252 is provided with a foolproof structure 225d, and the base 2123 is provided with a foolproof mating structure 217.

[0125] Please refer to Figure 2 This application provides a liquid storage assembly 22, which includes a porous element 230, a housing 221 and a sealing seat 225 connected to the housing 221. A storage cavity 222 for storing a liquid matrix is ​​provided between the housing 221 and the sealing seat 225. In this cavity 222, a portion of the liquid matrix is ​​kept in a free-flowing state, while a portion of the liquid matrix is ​​adsorbed by the porous element 230.

[0126] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification.
