Description

Technical Field

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

[0002] An aerosol generating device is a device including an atomizer used to atomize liquid formulations to generate aerosols. However, due to the size limitation of the atomizer, the amount of liquid formulation that can be stored in the atomizer is limited. An exemplary aerosol generating device exists, including an atomizer and a reservoir for storing the liquid formulation, the reservoir being connected to the atomizer. The aerosol generating device has an exposed operating element for user operation to open a fluid passage between the reservoir and the atomizer, thereby allowing the reservoir to replenish the atomizer with liquid formulation.

[0003] However, exposed operating components not only disrupt the surface uniformity of the aerosol generating device, but also result in the aerosol generating device having more parts, which is not conducive to reducing the cost of the aerosol generating device. Utility Model Content

[0004] The purpose of this application is to provide an aerosol generating device and atomizer that can effectively reduce the number of parts.

[0005] At least some embodiments of this application provide an aerosol generating apparatus, which includes an atomizer and a storage component connected to the atomizer;

[0006] The atomizer includes:

[0007] The shell has an internal first storage cavity for storing the aerosol generation matrix;

[0008] Atomizing core, used to atomize an aerosol-generating matrix to produce an aerosol; and

[0009] A movable component is disposed inside the housing and is capable of moving relative to the housing from a first position to a second position;

[0010] The storage component has a second storage cavity for storing aerosol generation matrix. The storage component is configured to be operable to drive the movable component from a first position to a second position. When the movable component is in the second position, a fluid channel between the second storage cavity and the first storage cavity is opened, so that the second storage cavity can replenish the first storage cavity with aerosol generation matrix.

[0011] As an example, the atomizer further includes a retainer, the movable member being movably connected to the retainer, and the movable member and / or the retainer having a guide hole for guiding the aerosol generating matrix in the second storage chamber into the first storage chamber; the guide hole is configured to open when the movable member is in the second position and close when the movable member is in the first position.

[0012] As an example, the flow guide hole includes a first flow guide hole formed on the retainer and communicating with the first storage cavity. When the movable member is in the second position, the first flow guide hole is in fluid communication with the first storage cavity and the second storage cavity. When the movable member is in the first position, the first flow guide hole is closed.

[0013] As an example, when the movable part is in the first position, at least a portion of the movable part covers or blocks the first guide hole, thereby closing the first guide hole.

[0014] As an example, it also includes a first seal held on the movable part, the first seal being used to provide a seal between the movable part and the retaining part.

[0015] As an example, the flow guide hole further includes a second flow guide hole formed on the movable member, the second flow guide hole being configured to be offset from the first flow guide hole when the movable member is in the first position, and at least partially aligned with the first flow guide hole when the movable member is in the second position.

[0016] As an example, a first seal is also included, which is configured to be located between the first flow guide orifice and the second flow guide orifice when the movable member is in the first position, and to provide a seal between the movable member and the retainer, and to be located on the same side of the first flow guide orifice and the second flow guide orifice when the movable member is in the second position.

[0017] As an example, a second seal is also included, which is configured to be located on the same side of the first flow channel as the first seal when the movable member is in the first position, and on opposite sides of the first flow channel when the movable member is in the second position, and to provide a seal between the movable member and the retainer.

[0018] As an example, the movable component has a flow-guiding cavity inside that communicates with the second flow-guiding hole. One end of the flow-guiding cavity is a closed end, and the other end is an open end for communicating with the second storage cavity or for receiving at least part of the storage component. The second flow-guiding hole is located between the closed end and the open end.

[0019] As an example, one of the retaining member and the movable member is provided with a guide groove, and the other is provided with a mating part; when the movable member moves between the first position and the second position, the mating part is configured to move along the guide groove.

[0020] As an example, the atomizer also includes a mouthpiece, the first storage cavity having a proximal end adjacent to the mouthpiece and a distal end disposed opposite to the proximal end, the retainer extending from the distal end toward the proximal end and the first flow guide being disposed close to the proximal end.

[0021] As an example, at least a portion of the atomizer core is located within the first storage cavity, and the first flow channel is closer to the proximal end than the atomizer core; and / or

[0022] The atomizer further includes a tube that is at least partially disposed in the first storage cavity and communicates with the mouthpiece. The side wall of the tube is provided with a liquid inlet for guiding the aerosol generation matrix in the first storage cavity into the atomizing core. At least part of the liquid inlet is located in the first storage cavity, and the first guide hole is closer to the proximal end than the liquid inlet.

[0023] As an example, the atomizer also includes a mouthpiece and a tube configured to receive at least a portion of the atomizing core and / or to guide aerosol to the mouthpiece, and the tube and the retainer are disposed parallel to each other in the first storage cavity.

[0024] As an example, the movable part is configured to remain in the second position when the reserve part is connected to the atomizer; and / or

[0025] The atomizer and the reserve are configured to be stored separately, and the movable part remains in the first position when the atomizer and the reserve are separated.

[0026] As an example, the reserve element is configured to be removably connected to the atomizer, which also includes a reset element that interferes with the movable element to provide a force to automatically reset the movable element to the first position after the reserve element is removed.

[0027] At least some embodiments of this application provide an atomizer, the atomizer comprising:

[0028] The shell has an internal first storage cavity for storing the aerosol generation matrix;

[0029] Atomizing core, used to atomize the aerosol generating matrix to produce aerosols;

[0030] The nozzle is in fluid communication with the atomizing core to deliver the aerosol;

[0031] The retainer extends at least partially into the first storage cavity and has a first flow guide hole thereon; and

[0032] The movable member is movably connected to the retainer and is movable relative to the retainer from a first position to a second position. The first flow guide hole is configured to be closed when the movable member is in the first position and open when the movable member is in the second position, thereby allowing the aerosol generation matrix to be replenished into the first storage cavity.

[0033] The first storage cavity has a proximal end adjacent to the suction nozzle and a distal end opposite to the proximal end, and the first flow guide hole is disposed near the proximal end.

[0034] In the aerosol generating apparatus provided in the above embodiments, the atomizer includes a movable component, and a storage component is configured to be operable to drive the movable component from a first position to a second position. When the movable component is in the second position, the second storage chamber in the storage component is in fluid communication with the first storage chamber in the atomizer, allowing the second storage chamber to replenish the aerosol generating matrix to the first storage chamber. This eliminates the need for additional operating components to drive the movable component to the second position, reducing the number of components in the aerosol generating apparatus and helping to lower the production cost and improve the production efficiency of the aerosol generating apparatus.

[0052] Please refer to Figures 1-6 This application provides an embodiment of an aerosol generating device 100, which includes an atomizer 1 configured to connect to a storage unit 2. The atomizer 1 includes an atomizing core 12 capable of acting on an aerosol generating matrix to generate aerosol. The atomizer 1 also includes a housing 13 with a first storage chamber 11 internally configured to store the aerosol generating matrix. The storage unit 2 has a second storage chamber 21 for storing the aerosol generating matrix. The storage unit 2 replenishes the atomizer 1 with the aerosol generating matrix, thereby extending the time for the atomizing core 12 to atomize the aerosol generating matrix and generate aerosol. This allows for full utilization of the atomizing core 12 and other components in the aerosol generating device 100, helping to reduce the operating cost and waste of the aerosol generating device 100.

[0053] In some embodiments, the aerosol generating apparatus 100 does not include the storage component 2. Further, see... Figure 1 and Figure 2 The aerosol generating device 100 includes a receiving cavity 3 for receiving the storage component 2, wherein at least a portion of the storage component 2 is received in the receiving cavity 3 when the storage component 2 is connected to the atomizer 1.

[0054] In some embodiments, the aerosol generating device 100 includes a reservoir 2, and further, the aerosol generating device 100 includes a receiving cavity 3 for receiving at least a portion of the reservoir 2.

[0055] The atomizer 1 also includes a movable member 14, specifically configured to move from a first position to a second position. When the movable member 14 is in the second position, the fluid passage between the second storage chamber 21 and the first storage chamber 11 is open, allowing the second storage chamber 21 to replenish the aerosol generating matrix to the first storage chamber 11. Understandably, when the movable member 14 is in the first position, the first storage chamber 11 is sealed, preventing it from receiving replenishment of the aerosol generating matrix from the reservoir 2 and preventing leakage of the aerosol generating matrix from the first storage chamber 11. It should be noted that the sealing of the first storage chamber 11 when the movable member 14 is in the first position mainly refers to the sealing of at least a portion of the area or components on the atomizer 1 used for connection to the reservoir 2 and for allowing the aerosol generating matrix to be replenished from the second storage chamber 21 to the first storage chamber 11.

[0056] In some embodiments, during the initial use of the atomizer 1 or when there is a sufficient aerosol generating matrix in the atomizer 1, the aerosol generating matrix can be prevented from being added to the first storage chamber 11 by positioning the movable member 14 in the first position, so as to prevent the first storage chamber 11 from becoming oversaturated and to prevent the aerosol generating matrix from leaking from the first storage chamber 11.

[0057] In some embodiments, after the atomizer 1 has been used for a period of time or when the aerosol generating matrix in the atomizer 1 is insufficient, the second storage chamber 21 can replenish the aerosol generating matrix to the first storage chamber 11 by moving the movable member 14 to the second position, so that the atomizing core 12 can continue to work and the aerosol generating device 100 can continue to provide aerosol.

[0058] In some embodiments, the aerosol generating apparatus 100 is configured to accept both basic and advanced operations. After the aerosol generating apparatus 100 accepts basic operation, the movable element 14 moves from a first position to a second position, thereby opening a fluid channel between the second storage chamber 21 and the first storage chamber 11. After the aerosol generating apparatus 100 accepts advanced operation, at least a portion of the aerosol generating matrix in the second storage chamber 21 is transferred to the first storage chamber 11 through the opened fluid channel. For example, when the fluid channel between the second storage chamber 21 and the first storage chamber 11 is open, at least a portion of the aerosol generating matrix in the second storage chamber 21 can be transferred to the first storage chamber 11 under gravity by tilting or inverting the aerosol generating apparatus 100.

[0059] In some embodiments, the reserve member 2 is configured to be operable to drive the movable member 14 from a first position to a second position. This eliminates the need for additional operating components to drive the movable member 14 to the second position, reducing the number of parts in the aerosol generating apparatus 100 and helping to lower the production cost and improve the production efficiency of the aerosol generating apparatus 100.

[0060] In this design, the user can directly operate the storage component 2, thereby driving the movable component 14 from the first position to the second position by directly acting on the storage component 2. Alternatively, the user can drive the storage component 2 through other components or tools, and then drive the movable component 14 from the first position to the second position through the storage component 2. That is, the user can indirectly operate the storage component 2, first driving the storage component 2 through a medium, and then driving the movable component 14 from the first position to the second position through the storage component 2. For example, after the storage component 2 is assembled into the receiving cavity 3, when the receiving cavity 3 is covered by a cover, the cover can drive the storage component 2 to move further, thereby causing the movable component 14 to move from the first position to the second position. It should be noted that configuring the storage component 2 to be directly operable and to be indirectly operable are both inventive concepts of this application and fall within the protection scope of this application.

[0061] In some embodiments, the atomizer 1 and the storage element 2 are configured to be stored separately, and when the atomizer 1 and the storage element 2 are separated, the movable element 14 remains in a first position, such that the first storage chamber 11 is sealed.

[0062] Further, you can refer to Figure 1 and Figure 2The reserve element 2 is configured to be removably connected to the atomizer 1, thereby allowing the reserve element 2 to be replaced or removed. The atomizer 1 may also include a reset element 15 that interferes with the movable element 14 to provide a force after the reserve element 2 is removed from the atomizer 1, causing the movable element 14 to automatically reset to a first position. The reset element 15 includes, but is not limited to, an elastic element that primarily provides a spring force to hold the movable element 14 in the first position; the elastic element may include a spring or a silicone material.

[0063] In some embodiments, during the connection of the reservoir 2 with the atomizer 1, the reservoir 2 is configured to drive the movable member 14 from a first position to a second position.

[0064] In some embodiments, when the reservoir 2 is connected to the atomizer 1, the movable member 14 is configured to remain in a second position. At least a portion of the force required to hold the movable member 14 in the second position may be provided by the reservoir 2, but is not limited thereto.

[0065] It should be noted that the movable member 14 remaining in the second position when the reservoir 2 is connected to the atomizer 1 is optional, not mandatory. In other embodiments, the reservoir 2 is configured to be movably connected to the atomizer 1, allowing the reservoir 2 to move relative to the atomizer 1 after connection. Thus, while the reservoir 14 remains connected to the atomizer 2, the movable member 14 can perform at least one reciprocating motion between the first and second positions. Therefore, when it is necessary to replenish the aerosol generating matrix into the first storage chamber 11, the movable member 14 can be driven to the second position by operating the reservoir 2. When it is not necessary to replenish the aerosol generating matrix into the first storage chamber 11, the movable member 14 can return to the first position under the action of the reservoir 2 or the reset member 15.

[0066] In some embodiments, the aerosol-generating matrix includes nicotine. Nicotine may include nicotine or nicotine salts. Nicotine has a neurostimulatory effect and is used to provide the user with the pleasure of inhalation. The first aerosol generated by the first aerosol-generating matrix contains nicotine.

[0067] In some embodiments, the aerosol generating matrix includes flavorings used to stimulate the user's sense of smell to provide aroma or to stimulate the user's sense of taste to adjust flavor.

[0068] Flavoring agents may include cooling agents. Cooling agents make the aerosol refreshing and cool, which helps to enhance the throat-soothing effect. Cooling agents include, but are not limited to, at least one of: N,2,3-trimethyl-2-isopropylbutyramide (WS-23), menthol, peppermint oil, and N-ethyl-p-menthyl-3-carboxamide (WS-3).

[0069] Flavoring agents may include sweeteners. Sweeteners enhance the sweetness of the aerosol, improving its flavor. Sweeteners include, but are not limited to, N-[N-(3,3-dimethylbutyl)]-L-α-aspartic-L-phenylalanine 1-methyl ester (also known as neotame). Sweeteners may also include, but are not limited to, one or more of the following: sucralose, steviol glycosides, neotame, acesulfame potassium, aspartame, glycyrrhizin, sodium saccharin, cyclamate, and monk fruit extract.

[0070] Flavoring agents may include tobacco extracts. The main components of tobacco extracts include tobacco cellulose, tobacco leaf protein, and other substances with tobacco aroma, but do not include nicotine or similar substances. Tobacco extracts can enhance the similarity between the smoke and traditional cigarette smoke, giving the aerosol a traditional cigarette flavor.

[0071] Flavoring agents may include flavorings. Flavorings can reduce the irritation caused by tobacco extracts. For example, flavorings may include at least one of 2-acetylpyrazine, ethyl maltol, and methyl dihydrojasmonate. Flavorings may also include throat-soothing ingredients. Throat-soothing ingredients include, but are not limited to, at least one of eugenol, clove leaf oil, clove bud oil, Peruvian balsam oil, fenugreek tincture, star anise oil, vanilla bean tincture, tea polyphenols, lemon oil, and propylene glycol.

[0072] In some embodiments, the aerosol generating matrix includes both nicotine and flavoring agents.

[0073] In some embodiments, the aerosol generating matrix includes a liquid matrix that is liquid at room temperature. The atomizing core 12 includes a liquid-absorbing element and a heating element, with the heating element disposed on the liquid-absorbing element. The liquid-absorbing element can be a porous material used to guide the aerosol generating matrix into the atomization range of the heating element. The heating element is used to heat the atomized aerosol generating matrix, thereby generating an aerosol. The porous material can be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous material can be porous ceramic or porous metal; this application does not limit the structure and composition of the porous material.

[0074] Of course, the atomizing core 12 may also include an ultrasonic element capable of generating ultrasonic waves, which enables the atomizing core to atomize the liquid matrix into an aerosol using ultrasonic waves. The atomizing core may also include other elements capable of atomizing the aerosol-generating matrix into an aerosol.

[0075] In some embodiments, the atomizer 1 further includes a tube 16, which guides the aerosol generated by the atomizing aerosol generation matrix of the atomizing core 12 to the outlet 171 of the atomizer 1, so that the aerosol flows out of the atomizer 1 through the outlet 171. Further, see... Figures 1-6 At least a portion of the tube 16 is located in the first storage cavity 11, and the tube 16 is configured to extend longitudinally in the first storage cavity 11.

[0076] In some embodiments, the tube 16 connects the nozzle 17 and the atomizing core 12 of the aerosol generating device 100 to guide the aerosol generated by the atomizer 1 to the nozzle 17. The nozzle 17 is provided with an air outlet 171, and at least a portion of the nozzle 17 can be held in the mouth by a user, with the air outlet 171 facing the user's oral cavity when the user holds the nozzle 17. The user inhales the aerosol generated by the atomizer 1 by sucking through the nozzle 17.

[0077] Furthermore, the atomizer 1 includes a mouthpiece 17, or the mouthpiece 17 of the aerosol generating device 100 is disposed on the atomizer 1. Even further, the mouthpiece 17 is connected to the housing 13, or the mouthpiece 17 and the housing 13 are integrally formed.

[0078] Specifically, the mouthpiece 17 is located near the end of the housing 13 of the atomizer 1. Along the airflow direction, the atomizing core 12 and the tube 16 are located upstream of the air outlet 171, with the near end of the tube 16 facing the mouthpiece 17.

[0079] In some embodiments, at least a portion of the atomizing core 12 is retained within the fitting 16. In some embodiments, reference may be made to... Figures 1-6 The side wall of the tube 16 is provided with a liquid inlet 161 for guiding the aerosol generating matrix in the first storage cavity 11 into the atomizing core 12. Preferably, at least a portion of the liquid inlet 161 is located in the first storage cavity 11, or the proximal end of the liquid inlet 161 is located in the first storage cavity 11.

[0080] In other embodiments (not shown), the atomizer further includes a compartment located upstream of the tube along the airflow direction, with the atomizing core disposed in the compartment. The compartment is connected to the first storage chamber via a liquid channel, allowing the aerosol generation matrix in the first storage chamber to be transferred to the atomizing core. The compartment is in fluid communication with the tube, so that the aerosol formed in the compartment can be discharged by the tube.

[0081] In some embodiments, the atomizer 1 further includes a liquid reservoir element (not shown), which has a large number of pores and is capable of adsorbing a large amount of liquid matrix. The liquid reservoir element is disposed in a first storage cavity 11, and at least partially of the liquid matrix stored in the first storage cavity 11 is retained in the liquid reservoir element, thereby preventing leakage of the aerosol generation matrix from the first storage cavity 11. The liquid reservoir element includes, but is not limited to, one of the following materials: cotton fiber, polypropylene fiber, polyester fiber, nylon fiber, porous ceramic material, polymer fiber, or various combinations of the above materials.

[0082] In some embodiments, reference may be made to Figure 1 and Figure 4The aerosol generating device 100 also includes a power supply component 4, which can provide electrical power to the atomizer 1, so that the atomizing core 12 atomizes the aerosol generating matrix to generate aerosol.

[0083] The power supply assembly 4 may include a power source, which can be any suitable battery, such as a lithium battery, a rechargeable battery, or a disposable battery. In some embodiments, the power supply assembly 4 further includes a circuit board electrically connected to the power source, on which at least one controller is disposed. The controller is used to control the electrical power output of the power source, such as controlling the power supply power to the atomizer. Of course, the controller can also control other operations of the aerosol generating device 100, such as controlling the charging of the power source, thereby performing charging management and charging protection of the power source.

[0084] In some embodiments, the atomizer 1 further includes a retainer 18, and a movable member 14 is movably connected to the retainer 18. When the movable member 14 is in a second position, the movable member 14 and / or the retainer 18 are in fluid communication with the first storage chamber 11 and the second storage chamber 21. Thus, the movable member 14 and / or the retainer 16 have a guide hole for guiding the aerosol generating matrix in the second storage chamber 21 into the first storage chamber 11. When the movable member 14 is in the second position, the guide hole is open, thus opening the fluid channel between the first storage chamber 11 and the second storage chamber 21; when the movable member 14 is in the first position, the guide hole is closed, thus sealing the first storage chamber 11.

[0085] In some embodiments, reference may be made to Figures 1-6 The flow guide hole includes a first flow guide hole 181 formed on the retainer 18. The first flow guide hole 181 is in communication with the first storage cavity 11. When the movable member 14 is in the second position, the first flow guide hole 181 is in fluid communication with the first storage cavity 11 and the second storage cavity 21. When the movable member 14 is in the first position, the first flow guide hole 181 is closed.

[0086] As an example, you can refer to Figures 1-3 Along the direction in which the aerosol generating matrix in the first storage cavity 11 flows out through the first guide hole 181, when the movable member 14 is in the first position, at least a portion of the movable member 14 is disposed downstream of the first guide hole 181, thereby sealing the first guide hole 181 to prevent leakage of the aerosol generating matrix in the first storage cavity 11.

[0087] Further, you can refer to Figure 7 and Figure 8The retaining member 18 has a cavity 182 inside. The movable member 14 includes a blocking portion 141, at least partially disposed in the cavity 182, and the blocking portion 141 is configured to move linearly along the cavity 182. Thus, by driving the movable member 14 to move, when the movable member 14 is in a first position, at least partially of the movable member 14 is located on one side of the first flow guide hole 181, that is, downstream of the first flow guide hole 181 in the outflow direction of the aerosol generating matrix in the first storage cavity 11. When the movable member 14 is in a second position, at least partially of the movable member 14 is located on the opposite side of the first flow guide hole 181, thereby allowing the first flow guide hole 181 to fluidly communicate with the first storage cavity 11 and the second storage cavity 21. In this example, reference can be made to... Figures 1-3 When the movable member 14 is in the first position, at least a portion of the first guide hole 181 can be blocked by the movable member 14 by being offset from it, and thus closed. Of course, when the movable member 14 is in the first position, the first guide hole 181 can also correspond to the blocking part 141, so that the first guide hole 181 is covered by the blocking part 141 and thus closed.

[0088] Alternatively, the retainer 18 may have a cavity 182, and the movable member 14 may include a blocking portion 141. At least a portion of the blocking portion 141 is disposed within the cavity 182 and configured to rotate within the cavity 182. This allows the movable member 14 to rotate such that, when the movable member 14 is in a first position, a portion of the blocking portion 141 corresponds to and covers the first flow guide hole 181, while another portion is located downstream of the first flow guide hole 181 in the outflow direction of the aerosol-generating matrix in the first storage cavity 11, thus blocking the first flow guide hole 181. When the movable member 14 is in a second position, at least a portion of the first flow guide hole 181 is misaligned with the blocking portion 141, allowing the first flow guide hole 181 to fluidly communicate with the first storage cavity 11 and the second storage cavity 21. Of course, in other examples, the blocking portion 141 may also be disposed outside the retainer 18, and the first flow guide hole 181 may be opened or closed by rotating the movable member 14.

[0089] As another example (not shown), when the movable member is in the first position, the blocking portion on the movable member is disposed corresponding to the first guide hole, thereby covering, blocking, or filling the first guide hole, thus closing the first guide hole. In this example, the movable member can be disposed outside the retainer, or at least a portion of the movable member can be disposed inside the retainer. By driving the movable member to move along the extension direction of the retainer or driving the movable member to rotate relative to the retainer, the blocking portion can be disposed corresponding to the first guide hole or at least a portion of the first guide hole can be misaligned with the blocking portion, thereby opening or closing the first guide hole.

[0090] In some embodiments, reference may be made to Figures 1-6 The aerosol generating apparatus 100 further includes a first seal 5, which flows out of the aerosol generating matrix in the first storage cavity 11 through the first guide hole 181 in the direction of outflow. The first seal 5 is configured to be located downstream of the first guide hole 181 when the movable member 14 is in the first position, and to provide a seal between the movable member 14 and the retainer 18 to prevent leakage of the aerosol generating matrix in the first storage cavity 11 from through the first guide hole 181.

[0091] Furthermore, along the direction in which the aerosol generating matrix in the first storage cavity 11 flows out through the first guide hole 181, when the movable part 14 is in the second position, the first seal 5 is moved away from the downstream of the first guide hole 181, so that the first guide hole 181 is in fluid communication with the second storage cavity 21.

[0092] Furthermore, the first seal 5 is held on the movable member 14, so that the first seal 5 and the movable member 14 are linked. Thus, when the movable member 14 moves relative to the retainer 18, the first seal 5 can also move relative to the first guide hole 181, so that when the movable member 14 moves from the first position to the second position, the first seal 5 is moved away from the downstream of the first guide hole 181.

[0093] Preferably, the first seal 5 is partially arranged around the movable member 14.

[0094] In some embodiments, reference may be made to Figures 1-6 The flow guide also includes a second flow guide 142 formed on the movable member 14. The second flow guide 142 is configured to be offset from the first flow guide 181 when the movable member 14 is in the first position, thus closing the flow guide. When the movable member 14 is in the second position, at least a portion of the second flow guide 142 is aligned with the first flow guide 181, causing the flow guide to open, thereby enabling fluid communication between the first flow guide 181 and the second flow guide 142. Consequently, the aerosol generating matrix in the second storage cavity 21 can enter the first storage cavity 11 through the first flow guide 181 and the second flow guide 142.

[0095] In some embodiments, reference may be made to Figure 1 and Figure 2 The first seal 5 is configured to be located between the first flow guide hole 181 and the second flow guide hole 142 when the movable member 14 is in the first position, and to provide a seal between the movable member 14 and the retainer 18, thereby isolating the first flow guide hole 181 from the second flow guide hole 142, and preventing the aerosol generating matrix from flowing from the first flow guide hole 181 into the second flow guide hole 142 or from the second flow guide hole 142 into the first flow guide hole 181. See also... Figure 4 and Figure 5When the movable part 14 is in the second position, the first seal 5 is located on the same side of the first guide hole 181 and the second guide hole 142, so as not to affect the flow of the aerosol generation matrix between the first guide hole 181 and the second guide hole 142.

[0096] Further, you can refer to Figures 1-5 The aerosol generating apparatus 100 further includes a second seal 6, which is configured to be located on the same side of the first guide hole 181 as the first seal 5 when the movable member 14 is in the first position; and to provide a seal between the movable member 14 and the retainer 18 when the movable member 14 is in the second position, and to be located on opposite sides of the first guide hole 181 as the first seal 5. This is to prevent the aerosol generating matrix from entering and leaking through the gap between the retainer 18 and the movable member 14 when the second guide hole 142 is at least partially aligned with the first guide hole 181.

[0097] In some embodiments, reference may be made to Figures 1-5 Along the direction in which the aerosol-generating matrix in the first storage cavity 11 flows out through the first guide hole 181, when the movable member 14 is in the first position, the first seal 5 and the second seal 6 are simultaneously located downstream of the first guide hole 181. When the movable member 14 is in the second position, the first seal 5 is moved away from the downstream of the first guide hole 181, but the second seal 6 remains downstream of the first guide hole 181.

[0098] In the direction in which the aerosol generating matrix in the first storage cavity 11 flows out through the first guide hole 181, when the movable member 14 is in the second position, the second sealing member 6 is preferably located downstream of both the first guide hole 181 and the second guide hole 142.

[0099] In some embodiments, the second seal 6 is held on the movable member 14 such that the second seal 6 is linked to the movable member 14. Thus, when the movable member 14 moves relative to the retainer 18, the second seal 6 can also move relative to the retainer 18, thereby changing its position downstream of the first guide hole 181 when the movable member 14 moves from the first position to the second position.

[0100] Preferably, the second seal 6 is disposed at least partially around the movable member 14. Preferably, the first seal 5 and the second seal 6 are made of the same material and / or have the same shape and structure.

[0101] In some embodiments, reference may be made to Figures 1-5The movable member 14 has a flow-guiding cavity 143 communicating with the second flow-guiding hole 142. One end of the flow-guiding cavity 143 is a closed end, and the other end is an open end for communicating with the second storage cavity 21 or for receiving the storage member 2 at least partially. The second flow-guiding hole 142 is located between the closed end and the open end. Furthermore, the second flow-guiding hole 142 is formed on the side wall of the movable member 14. In one example, the movable member 14 includes a blocking portion 141 at one end of the flow-guiding cavity, which closes one end of the flow-guiding cavity 143 to form a closed end.

[0102] In some embodiments, the movable member 14 includes a first movable member 144 and a second movable member 145. The second movable member 145 is capable of being connected to or docked with the storage member 2, and when the second movable member 145 is connected to or docked with the storage member 2, the flow guide cavity 143 and / or the second flow guide hole 142 are in fluid communication with the second storage cavity 21.

[0103] The second guide hole 142 may be formed on the side wall of the first movable member 144. The first seal 5 and the second seal 6 may be held on the first movable member 144. The first movable member 144 may include an injection-molded part. The second movable member 145 may include a metal part made of metal. The first movable member 144 and the second movable member 145 may be riveted so that one is embedded into the other. The first movable member 144 and the second movable member 145 may be formed into an integral structure by insert injection molding.

[0104] In such Figure 4 In the embodiment shown, the second movable member 145 includes a first tubular portion 1451 and a second tubular portion 1452. The first movable member 144 is connected to the first tubular portion 1451, and the second tubular portion 1452 is configured to be connected to or dock with the storage member 2.

[0105] When the reservoir 2 is connected to the atomizer 1, a portion of the reservoir 2 can be received in the second tubular portion 1452. Furthermore, the inner diameter of the second tubular portion 1452 is larger than the inner diameter of the first tubular portion 1451, thereby forming a stepped structure inside the second movable member 145 and at the boundary between the first tubular portion 1451 and the second tubular portion 1452. This stepped structure abuts against the reservoir 2 when it is received in the second tubular portion 1452, preventing the reservoir 2 from entering deeper into the movable member 14.

[0106] Furthermore, at least a portion of the outer wall of the second tubular portion 1452 protrudes outward relative to the outer wall of the first tubular portion 1451 to form a support portion, or a support portion is provided on the outer wall of the second movable member 145, and one end of the reset member 15 abuts against the support portion, so that the reset member 15 can act on the movable member 14, causing the movable member 14 to be held in the first position or reset to the first position. The other end of the reset member 14 can abut against the retainer 18.

[0107] Preferably, the second movable part 145 is made of metal, so that the stepped structure and the support can be formed simultaneously by stamping.

[0108] The wall thickness of the second movable part 145 can be less than the wall thickness of the first movable part 144. Alternatively, the wall thickness of the metal part can be less than the wall thickness of the injection molded part.

[0109] In some embodiments, reference may be made to Figure 5 The first movable member 144 is slidably connected to the first retainer 183, and one of the first movable member 144 and the first retainer 183 is a metal part, while the other is an injection molded part. In some embodiments, reference can be made to... Figure 5 The second movable part 145 is slidably connected to the second retaining part 184, and one of the second movable part 145 and the second retaining part 184 is a metal part and the other is an injection molded part.

[0110] In some embodiments, reference may be made to Figures 1-6 The aerosol generating apparatus 100 further includes a sealing plug 7 defining at least a partial boundary of the distal end of the first storage cavity 11. The sealing plug 7 is held on a retainer 18, which is connected to the housing 13. The sealing plug 7 provides a seal between the retainer 18 and the housing 13. The distal end of the tube 16 may be interference-fitted into the sealing plug 7 or interference-fitted through the sealing plug 7 and connected to the retainer 18.

[0111] Further, you can refer to Figure 5 The retainer 18 includes a first retainer 183 and a second retainer 184. A first guide hole 181 is formed on the first retainer 183, and a sealing plug 7 is held on the second retainer 184. Preferably, the first retainer 181 is connected to the second retainer 184 substantially vertically.

[0112] When the reservoir 2 is connected to the atomizer 1, the second retainer 184 can be connected to the reservoir 2. The aerosol generating device 100 may also include a third seal 8, which provides a seal between the reservoir 2 and the second retainer 184 when the reservoir 2 is connected to the second retainer 184.

[0113] The first retainer 183 may include a metal part made of metal. The second retainer 184 may include an injection-molded part. The first retainer 183 and the second retainer 184 may be riveted together so that one is embedded into the other for retention. The first retainer 183 and the second retainer 184 may be integrally formed by insert injection molding. One end of the reset member 15 may abut against the second retainer 184, and the other end may abut against the movable member 14.

[0114] The wall thickness of the first retainer 183 may be less than the wall thickness of the second retainer 184.

[0115] In some embodiments, the movable member 14 is inseparably connected to the retainer 18, or the force separating the reserve member 2 from the movable member 14 is less than the force separating the movable member 14 from the retainer 18. Thus, when the reserve member 2 is removed from the atomizer 1, the movable member 14 can remain in the atomizer 1, waiting to be driven again by the reserve member 2 to move to the second position when the reserve member 2 is reconnected to the atomizer 1 or when a new reserve member 2 is connected to the atomizer 1.

[0116] In some embodiments, one of the retainer 18 and the movable member 14 is provided with a guide groove 185, and the other is provided with a mating portion 146; when the movable member 14 moves between a first position and a second position, the mating portion 146 is configured to move along the guide groove 185. The guide groove 185 and the mating portion 146 cooperate with each other to define the movement trajectory of the movable member 14 when it moves between the first position and the second position, which helps to ensure that the fluid passage between the first storage cavity 11 and the second storage cavity 21 can be connected when the movable member 14 is in the second position. The guide groove 185 may include a through groove that penetrates the sidewall of the retainer 18 or the movable member 14, or it may include a blind groove that does not penetrate the sidewall of the retainer 18 or the movable member 14.

[0117] When the movable member 14 is in the second position, the mating portion 146 can be interfered with by one end of the guide groove 185, thereby indicating that the fluid passage between the first storage cavity 11 and the second storage cavity 21 is open. When the movable member 14 is in the first position, the mating portion 146 can be interfered with by the other end of the guide groove 185, thereby indicating that the first storage cavity 11 has been sealed, and also helping to prevent the movable member 14 from disengaging from the retainer 18.

[0118] As an example, the first seal 5 is configured such that, when the movable member 14 is in the first position, it is simultaneously located downstream of both the guide groove 185 and the first guide hole 185 in the direction in which the aerosol generating matrix in the first storage cavity 11 flows out through the first guide hole 181 (see reference). Figure 1Alternatively, it may be located between the guide groove 185 and the first guide hole 184 to prevent the aerosol generating matrix in the first storage cavity 11 from leaking through the guide groove 185 when the movable part 14 is in the first position.

[0119] Furthermore, the second seal 6 is configured such that when the movable member 14 is in the second position, it is located on opposite sides of the first guide hole 181 and between the guide groove 185 and the first guide hole 181, or simultaneously downstream of the guide groove 185 and the first guide hole 181 in the direction in which the aerosol generating matrix in the first storage cavity 11 flows out through the first guide hole 181, to prevent the aerosol generating matrix in the second storage cavity 21 from leaking through the guide groove 185 when the movable member 14 is in the second position.

[0120] In some embodiments, reference may be made to Figure 4 and Figure 5 The first storage cavity 11 has a proximal end adjacent to the suction nozzle 17 and a distal end arranged opposite to the proximal end. A first guide hole 181 is located between the proximal and distal ends of the first storage cavity 11, and the longitudinal difference between the first guide hole 181 and the distal end of the first storage cavity 11 is greater than 0 cm, or the longitudinal difference between the first guide hole and the sealing plug is greater than 0 cm. This is to prevent the aerosol generating matrix of the first storage cavity 11 from flowing back into the first guide hole 181 and then flowing out of the first storage cavity 11 through the first guide hole 181 when the aerosol generating device 100 is being aspirated.

[0121] Furthermore, the retainer 18 extends from the distal end of the first storage cavity 11 toward the proximal end of the first storage cavity 11, and the first flow guide 181 is disposed close to the proximal end of the first storage cavity 11. In other words, the longitudinal distance between the central axis of the first flow guide 181 and the proximal end of the first storage cavity 11 is smaller than the longitudinal distance between the first flow guide 181 and the distal end of the first storage cavity 11, or the longitudinal distance between the proximal end of the first flow guide 181 and the proximal end of the first storage cavity 11 is smaller than the longitudinal distance between the distal end of the first flow guide 181 and the distal end of the first storage cavity 11.

[0122] In some embodiments, at least a portion of the atomizing core 12 and at least a portion of the first flow guide 181 are located in the first storage cavity 11, with the first flow guide 181 being closer to the proximal end of the first storage cavity 11 than the atomizing core 12. For example, the distal end of the first flow guide 181 is located longitudinally between the proximal end of the first storage cavity 11 and the proximal end of the atomizing core 12, and the longitudinal difference d between the distal end of the first flow guide 181 and the proximal end of the atomizing core 12 is greater than or equal to 0 cm. This further prevents the aerosol generating matrix in the first storage cavity 11 from flowing back into the first flow guide 181 when the aerosol generating device 100 is aspirated, which helps ensure that the atomizing core 12 can be fully wetted by the liquid matrix in the first storage cavity 11 when the aerosol generating device 100 is aspirated, and is beneficial for preventing the atomizing core 12 from dry burning.

[0123] In some embodiments, at least a portion of the liquid inlet 161 is located within the first storage cavity 11, and the first guide hole 181 is closer to the proximal end of the first storage cavity 11 than the liquid inlet 161. For example, the distal end of the first guide hole 181 is longitudinally located between the proximal end of the first storage cavity 11 and the proximal end of the first guide hole 181, and the longitudinal difference between the distal end of the first guide hole 181 and the proximal end of the liquid inlet 161 is greater than or equal to 0 cm. This is to prevent the liquid matrix in the first storage cavity 11 from flowing back into the first guide hole 181 when the aerosol generating device 100 is aspirated, thus preventing the liquid level of the liquid matrix in the first storage cavity 11 from being lower than the proximal or distal end of the liquid inlet 161, which would prevent the atomizing core 12 from being fully wetted by the liquid matrix in the first storage cavity 11 and thus posing a risk of interference to the atomizing core 12.

[0124] The aerosol generating matrix of the first storage cavity 11 can be prevented from flowing back into the first guide hole 181 when the aerosol generating device 100 is aspirated, by positioning the first guide hole 181 as close as possible in the longitudinal direction to the proximal end of the first storage cavity 11 and / or as far away as possible in the longitudinal direction from the distal end of the first storage cavity 11.

[0125] In some embodiments, reference may be made to Figure 1 and Figure 2 The tube 16 and the retainer 18 are arranged parallel to each other in the first storage cavity 11.

[0126] Furthermore, the tube 16 and the retainer 18 are arranged at intervals in the first storage cavity 11.

[0127] In some embodiments, reference may be made to Figure 1 The movable part 14 is located inside the housing 13 and is thus shielded, so that the movable part 14 does not affect the surface uniformity of the aerosol generating device 100.

[0128] In some embodiments, the housing 13 is at least partially transparent, allowing the viewer to observe the remaining amount of aerosol-generating matrix in the first storage cavity 11 through the housing 13. The timing for replenishing the first storage cavity 11 with aerosol-generating matrix by the second storage cavity 21 can be determined based on the remaining amount of aerosol-generating matrix in the first storage cavity 11.

[0129] In some embodiments, the reservoir 2 includes an operable operating part 22, which, when operated, causes the main body 23 of the reservoir 2 to drive the movable part 14 to move. The operating part 22 may be exposed when the reservoir 2 is connected to the atomizer 1 or when the reservoir is received in the receiving cavity 3.

[0130] Please refer to Figures 1-6 This application provides an embodiment of an atomizer 1, which includes:

[0131] The housing 13 has an internal first storage chamber 11 for storing the aerosol generation matrix;

[0132] Atomizing core 12 is used to atomize the aerosol generating matrix to produce aerosols;

[0133] Mouthpiece 17, which is in fluid communication with atomizing core 12 to deliver aerosol;

[0134] The retainer 18 extends at least partially into the first storage cavity 11, and the retainer 18 has a first flow guide hole 181; and

[0135] The movable member 14 is movably connected to the retainer 18, and the movable member 14 is movable relative to the retainer 18 from a first position to a second position. The first guide hole 181 is configured to be closed when the movable member 14 is in the first position and open when the movable member 14 is in the second position, thereby allowing the aerosol generation matrix to be replenished into the first storage cavity 11.

[0136] The first storage cavity 11 has a proximal end adjacent to the suction nozzle 17 and a distal end opposite to the proximal end of the suction nozzle 17, and the first guide hole 181 is located near the proximal end of the suction nozzle 17.

[0137] 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. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
