[0002] This application is based on Chinese Patent Application No. 202421629187.7, filed on July 10, 2024, entitled “Electronic Atomizing Device and Atomizer”, and claims priority to the aforementioned Chinese Patent Application, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of atomization technology, specifically to an aerosol generating device. Background Technology

[0004] Aerosol generating devices are used to generate aerosols for users to inhale.

[0005] The aerosol generating device includes an atomizer and an auxiliary oil tank. The atomizing core in the atomizer absorbs the aerosol generating matrix and converts it into aerosols. After the aerosol generating matrix in the atomizer is consumed to a certain extent, the aerosol generating matrix stored in the auxiliary oil tank enters the atomizer through its outlet to replenish it, thereby extending the service life of the aerosol generating device.

[0006] In related technologies, the additional oil tank is kept in fluid communication with the atomizer, which may cause an excessive amount of aerosol production matrix to flow into the atomizer. This may result in at least a portion of the atomizer core being directly immersed in the aerosol production matrix, which is not conducive to the concentration of the aerosol formed by the atomizer core meeting the preset concentration requirements and has an adverse impact on the user's experience. Utility Model Content

[0007] In view of this, the embodiments of this application aim to provide an aerosol generation device that, during use, restricts the direct flow of the aerosol generation matrix in the auxiliary oil tank into the atomizer.

[0008] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0009] This application provides an aerosol generating device, the aerosol generating device comprising:

[0010] Atomizer, including an atomizing component and a first liquid reservoir, the atomizing component including an outlet channel and a main storage chamber, the outlet channel being isolated from the main storage chamber, the outlet channel extending along a first direction, the outlet of the outlet channel communicating with the outside of the aerosol generating device, and at least a portion of the first liquid reservoir being located within the main storage chamber;

[0011] An auxiliary oil tank is provided with an auxiliary storage chamber and a fluid channel. The fluid channel is used to connect the auxiliary storage chamber with the main storage chamber. The fluid channel is located on the side of the auxiliary storage chamber near the outlet of the gas outlet channel along the first direction.

[0012] In some embodiments, at least a portion of the main storage cavity is located on at least one side of the additional storage cavity along a second direction, the first direction intersecting the second direction.

[0013] In some embodiments, the atomizing assembly further includes a main channel that connects the fluid channel and the main storage chamber. The main channel is located on one side of the main storage chamber along the second direction. The main channel connects the main storage chamber and forms a main connection port at the connection position. The main connection port is located on the side of the main storage chamber along the first direction near the outlet of the air outlet channel.

[0014] In some embodiments, the first reservoir covers at least a portion of the main communication port.

[0015] In some embodiments, the main channel includes a first sub-channel and a second sub-channel, and the atomizing component includes a sealing cap and a mounting shell. The mounting shell has a first mounting groove, which is open on one side along the first direction, and the inner wall of the other side has a second sub-channel that extends through the first direction. The sealing cap is placed on the open position of the first mounting groove and is spaced apart from at least a portion of the inner wall of the first mounting groove along the first direction to form the first sub-channel. The first sub-channel communicates with the second sub-channel.

[0016] In some embodiments, the additional storage chamber is located on the side of the main storage chamber away from the outlet of the vent passage along the first direction.

[0017] In some embodiments, the additional oil reservoir includes a housing assembly and a second liquid storage element. The additional storage cavity and the fluid channel are located in the housing assembly. At least one of the additional storage cavity and the fluid channel is provided with the second liquid storage element. When the main storage cavity is in communication with the additional storage cavity, the first liquid storage element and the second liquid storage element are fluidly connected. The capillary attraction of the first liquid storage element to the aerosol generating matrix is ​​not less than the capillary attraction of the second liquid storage element to the aerosol generating matrix.

[0018] In some embodiments, one end of the second liquid storage element along the first direction abuts against the inner wall of the auxiliary storage cavity on the side away from the main storage cavity, and the other end abuts against the first liquid storage element.

[0019] In some embodiments, the additional oil tank is provided with a placement hole that is open on at least one side along the first direction, and at least a portion of the atomizer is located within the placement hole.

[0020] In some embodiments, the atomizing assembly includes an atomizing core and a mounting assembly. The mounting assembly has a mounting cavity and the air outlet channel. The atomizing core is disposed in the mounting cavity and surrounds the inner wall of the mounting cavity to form a main storage cavity. At least a portion of the atomizing core is located in the placement hole.

[0021] In some embodiments, the additional oil tank includes a sealing movable block and a housing assembly, the housing assembly including the fluid channel and the additional storage chamber, the fluid channel communicating with the outside of the housing assembly, the sealing movable block having a through-through transition channel, and the atomizer capable of pushing the sealing movable block to move relative to the housing assembly to switch the additional oil tank between a connected state and a sealed state;

[0022] In the sealed state, the sealing movable block closes the fluid passage; in the connected state, the fluid passage opens to connect the main storage chamber with the auxiliary storage chamber.

[0023] In some embodiments, one of the auxiliary oil tank and the atomizer is provided with a slider, and the other is provided with a chute and a limiting groove. The chute extends along the through direction of the transfer channel, with one end of the chute open to form an inlet and outlet and the other end communicating with the limiting groove. The limiting groove extends along the rotation direction of the sealing movable block and has a limiting surface on one side along the rotation direction of the sealing movable block. The slider can enter and exit the chute through the inlet and outlet and slide within the chute and the limiting groove. In the communicating state, the slider abuts against the limiting surface along the rotation direction of the sealing movable block.

[0024] The aerosol generating device in this embodiment of the application, on the one hand, by setting a first liquid storage component, can first absorb the aerosol generating matrix entering the main storage chamber, and then release the aerosol generating matrix to the atomizing component. This helps to limit the rate at which the aerosol generating matrix is ​​replenished to the atomizing component, reducing the probability that at least part of the atomizing component is immersed in the aerosol generating matrix and thus affecting the taste of the aerosol inhaled by the user. On the other hand, during the user's inhalation, due to the influence of gravity, the aerosol generating matrix in the additional storage chamber is difficult to enter the fluid channel and then enter the main storage chamber. This allows the atomizing component to mainly consume the aerosol generating matrix in the main storage chamber, making it easier to control the rate at which the atomizing component generates aerosol. This further helps to reduce the probability that at least part of the atomizing component is immersed in the aerosol generating matrix and thus affecting the taste of the aerosol inhaled by the user.

Detailed Implementation

[0043] It should be noted that, in the absence of conflict, the technical features in the embodiments of this utility model can be combined with each other, and the detailed description in the specific embodiments should be understood as an explanation of the purpose of the embodiments of this utility model, and should not be regarded as an improper limitation on the embodiments of this utility model.

[0044] In the description of the embodiments of this utility model, the orientation or positional relationship of the "first direction" is based on the orientation or positional relationship shown by arrow X in the accompanying drawings; the orientation or positional relationship of the "second direction" is based on the orientation or positional relationship shown by arrow Y in the accompanying drawings.

[0045] It should be understood that these directional terms are only for the convenience of describing the embodiments of the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of the present invention.

[0046] This application provides an aerosol generating device for forming an aerosol from an aerosol generating matrix through heating or other means for users to inhale.

[0047] See Figures 1 to 4 , Figure 12 and Figure 13 The aerosol generating device includes an atomizer 10 and an auxiliary oil tank 20.

[0048] The atomizer 10 includes an atomizing component 11 and a first liquid storage component 12. The atomizing component 11 includes an outlet channel 10b and a main storage chamber 10a. The outlet channel 10b is isolated from the main storage chamber 10a. The outlet channel 10b extends along a first direction and its outlet is connected to the outside of the aerosol generating device. At least a portion of the first liquid storage component 12 is located inside the main storage chamber 10a.

[0049] The outlet end of the air outlet channel 10b can be used directly as a suction nozzle, or it can be connected to a separate suction nozzle.

[0050] The auxiliary oil tank 20 is provided with an auxiliary storage chamber 20a and a fluid channel 20b. The fluid channel 20b is used to connect the auxiliary storage chamber 20a with the main storage chamber 10a. The fluid channel 20b is located on the side of the auxiliary storage chamber 20a along the first direction near the outlet of the gas outlet channel 10b.

[0051] The atomizing component 11 includes an atomizing core 111, which is used to absorb the aerosol generating matrix in the main storage chamber 10a and convert the aerosol generating matrix into aerosol by means of heating or other methods.

[0052] The air outlet channel 10b is used to discharge the aerosol generated by the atomizer 10. During the user's inhalation of the aerosol, the aerosol enters the user's mouth through the outlet of the air outlet channel 10b.

[0053] The venting channel 10b is separated from the main storage chamber 10a so that the aerosol generation matrix in the main storage chamber 10a cannot enter the venting channel 10b and leak.

[0054] The first liquid storage component 12 has pores to store at least a portion of the aerosol generation matrix within the main storage chamber 10a via capillary action. The first liquid storage component 12 is in fluid communication with the atomizing component 11, allowing the aerosol generation matrix to flow from one to the other. The specific manner in which fluid communication is achieved between the two components is not limited; for example, they may be in direct contact, or a channel may be provided between them to allow fluid to pass through the channel and come into contact with both components.

[0055] After the first liquid storage component 12 comes into contact with the aerosol generating matrix, the aerosol generating matrix can be absorbed by the first liquid storage component 12 and stored in the space within the pores through capillary action; at least some of the pores are interconnected so that the aerosol generating matrix can pass through the first liquid storage component 12 and be transported to the atomizing core 111 of the atomizing component 11 which is in fluid communication with the first liquid storage component 12.

[0056] The auxiliary storage chamber 20a can store a certain amount of aerosol generation matrix. When the main storage chamber 10a and the auxiliary storage chamber 20a are connected through the fluid channel 20b, the aerosol generation matrix in the auxiliary storage chamber 20a can enter the main storage chamber 10a to replenish the amount of aerosol generation matrix in the main storage chamber 10a, so that the atomizer 10 can supply aerosol for a longer time.

[0057] The fluid channel 20b is located on the side of the auxiliary storage chamber 20a that is close to the outlet of the air outlet channel 10b along the first direction. That is, the auxiliary communication port 20c formed by the fluid channel 20b and the auxiliary storage chamber 20a is located on the inner wall of the auxiliary storage chamber 20a on the side that is close to the outlet of the air outlet channel 10b along the first direction.

[0058] It should be noted that the inner wall of the auxiliary storage cavity 20a near the outlet of the air outlet channel 10b along the first direction refers to the inner wall of one part of the space near the outlet of the air outlet channel 10b, which is located in the two parts of the space separated by the perpendicular bisector of the line connecting the two points with the greatest distance along the first direction of the auxiliary storage cavity 20a.

[0059] During the process of the user drawing aerosol, the first direction is roughly vertical, the outlet of the air outlet channel 10b faces upward, the additional connection port 20c is located on the top wall of the additional storage chamber 20a away from the ground, and the aerosol generation matrix in the additional storage chamber 20a tends to flow and deposit on the side of the additional storage chamber 20a near the ground under the action of gravity.

[0060] The aerosol generating device in this embodiment has several advantages. First, by providing a first liquid storage component 12, it can first absorb the aerosol generating matrix entering the main storage chamber 10a and then release the aerosol generating matrix to the atomizing component 11. This helps to limit the rate at which the aerosol generating matrix is ​​replenished to the atomizing component 11, reducing the probability that at least part of the atomizing component 11 will be immersed in the aerosol generating matrix and affect the taste of the aerosol inhaled by the user. Second, during the inhalation process, due to gravity, the aerosol generating matrix in the additional storage chamber 20a is difficult to enter the fluid channel 20b and then the main storage chamber 10a. This allows the atomizing component 11 to mainly consume the aerosol generating matrix in the main storage chamber 10a, making it easier to control the rate at which the atomizing component 11 generates aerosols. This further helps to reduce the probability that at least part of the atomizing component 11 will be immersed in the aerosol generating matrix and affect the taste of the aerosol inhaled by the user.

[0061] It is understandable that, in the absence of the user using the aerosol production device, the aerosol production device can be inverted so that the outlet of the gas outlet channel 10b faces downwards, and the additional connection port 20c is located on the bottom wall of the additional storage chamber 20a near the ground. The aerosol generation matrix can then enter the fluid channel 20b and replenish the main storage chamber 10a.

[0062] It is understandable that the pores of the first liquid storage component 12 can be macroscopically visible to the naked eye or microscopically invisible to the naked eye, as long as they meet the requirements of absorbing aerosols through capillary action to generate a matrix and allowing airflow to pass through.

[0063] In some embodiments, see Figure 3 and Figure 4 The additional communication port 20c formed by the fluid channel 20b and the additional storage chamber 20a is located on the inner wall of the additional storage chamber 20a at one end near the outlet of the air outlet channel 10b along the first direction.

[0064] This further reduces the probability that the aerosol-generated matrix in the additional storage chamber 20a will enter the additional channel fluid channel 20b and then the main storage chamber 10a.

[0065] It should be noted that the inner wall of the auxiliary storage cavity 20a near the outlet of the air outlet channel 10b along the first direction refers to the inner wall of one part of the space near the outlet of the air outlet channel 10b that is furthest from the perpendicular bisector of the line formed between the two points that are the largest distance apart along the first direction in the auxiliary storage cavity 20a. The extension direction of this wall is not parallel to the first direction.

[0066] The specific form of the first liquid storage component 12 is not limited, such as fibrous structures woven or twisted from cotton, sponge, polyester, nylon and other chemical fibers, or porous materials such as ceramics.

[0067] It is understandable that the aerosol generating matrix is ​​made of a wetting liquid relative to the material of the first liquid storage component 12, so that the aerosol generating matrix can adhere to or be absorbed by the first liquid storage component 12.

[0068] In some embodiments, see Figure 3 and Figure 4 At least a portion of the main storage cavity 10a is located on at least one side of the auxiliary storage cavity 20a along a second direction, where the first direction intersects the second direction.

[0069] This allows for a reduction in the overall profile dimensions of the atomizer 10 and the auxiliary oil tank 20 along the first direction while maintaining the same dimension of the air outlet channel 10b along the first direction.

[0070] In some embodiments, the first direction and the second direction are perpendicular to each other.

[0071] In some embodiments, see Figure 3 and Figure 4 The atomizing component 11 also includes a main channel 10c, which connects the fluid channel 20b and the main storage chamber 10a.

[0072] In some embodiments, see Figure 4 The main channel 10c is located on one side of the main storage cavity 10a along the second direction. The main channel 10c connects to the main storage cavity 10a and forms a main connection port 10d at the connection position. The main connection port 10d is located on the side of the main storage cavity 10a along the first direction near the outlet of the air outlet channel 10b.

[0073] The main channel 10c is located on one side of the main storage cavity 10a along the second direction, meaning that the main channel 10c and the main storage cavity 10a are arranged along the second direction.

[0074] Thus, with the outlet of the gas outlet channel 10b facing downwards, the aerosol generation matrix entering the main channel 10c can flow directly into the main storage chamber 10a in the horizontal direction, which helps to improve the efficiency of replenishing the aerosol generation matrix into the main storage chamber 10a.

[0075] In some embodiments, see Figure 4 and Figure 9 The first liquid storage element 12 covers at least a portion of the main communication port 10d.

[0076] This allows the aerosol generating matrix to be absorbed more quickly by the first liquid storage device 12 after flowing out of the main channel 10c, reducing the probability of the aerosol generating matrix directly wetting the atomizing core 111. See some embodiments. Figure 3 and Figure 4 The main channel 10c includes a first sub-channel 10ca and a second sub-channel 10cb. The atomizing assembly 11 includes a sealing cap 1131 and a mounting shell 1132. The mounting shell 1132 is provided with a first mounting groove 1132a. The first mounting groove 1132a is open on one side along a first direction, and the inner wall of the other side is provided with a second sub-channel 10cb that runs through the first direction. The sealing cap 1131 is placed on the open position of the first mounting groove 1132a and is spaced apart from at least part of the inner wall of the first mounting groove 1132a along the first direction to form the first sub-channel 10ca. The first sub-channel 10ca communicates with the second sub-channel 10cb.

[0077] The main channel 10c is formed by assembling the sealing cover 1131 and the mounting shell 1132.

[0078] The sealing cap 1131 can be made of an elastic material, which helps to improve the sealing performance of the main channel 10c.

[0079] The first mounting groove 1132a is open along the first direction, and the second sub-channel 10cb extends along the first direction, thereby facilitating the one-time formation of the first mounting groove 1132a and the second sub-channel 10cb by drafting along the first direction.

[0080] In some embodiments, see Figure 4 The fluid channel 20b extends along a first direction to connect the main channel 10c and the additional storage chamber 20a, so that the aerosol can directly enter the main channel 10c under the action of gravity.

[0081] In some embodiments, see Figure 12 and Figure 13 The auxiliary storage chamber 20a is located on the side of the main storage chamber 10a away from the outlet of the exhaust passage 10b along the first direction.

[0082] Thus, with the outlet of the gas outlet channel 10b facing downwards, at least a portion of the main storage chamber 10a is located below the auxiliary storage chamber 20a, allowing the aerosol generating matrix in the auxiliary storage chamber 20a to flow directly downwards into the auxiliary storage chamber 20a under the influence of gravity, thereby improving the efficiency of replenishing the aerosol generating matrix into the auxiliary storage chamber 20a.

[0083] Understandably, with the user continuously drawing in aerosols, the aerosol generation matrix in the main storage chamber 10a is rapidly consumed, which can easily lead to the risk of dry burning of the atomizing component 11.

[0084] In some embodiments, see Figures 13 to 16 The auxiliary oil tank 20 includes a shell assembly 21 and a second liquid storage component 25. An auxiliary storage cavity 20a and a fluid channel 20b are located in the shell assembly 21. At least one of the auxiliary storage cavity 20a and the fluid channel 20b is provided with the second liquid storage component 25. When the main storage cavity 10a is in communication with the auxiliary storage cavity 20a, the first liquid storage component 12 and the second liquid storage component 25 are fluidly connected. The capillary attraction of the first liquid storage component 12 to the aerosol generating matrix is ​​not less than the capillary attraction of the second liquid storage component 25 to the aerosol generating matrix.

[0085] After the second liquid storage device 25 comes into contact with the aerosol generating matrix, the aerosol generating matrix can be absorbed by the second liquid storage device 25 and stored in the space within the pores through capillary action; at least some of the pores are interconnected so that the aerosol generating matrix can pass through the second liquid storage device 25 and come into contact with the first liquid storage device 12.

[0086] Since the capillary attraction of the first liquid storage device 12 to the aerosol generating matrix is ​​not less than that of the second liquid storage device 25 to the aerosol generating matrix, the aerosol generating matrix in the second liquid storage device 25 can flow to the first liquid storage device 12.

[0087] Thus, even if the aerosol generating device keeps the outlet of the air outlet channel 10b facing upwards, the second liquid storage unit 25 can still deliver the aerosol generating matrix to the first liquid storage unit 12, which helps to reduce the problem of dry burning of the atomizer 10. In addition, the aerosol generating matrix in the additional storage chamber 20a is supplied to the atomizing core 111 through the second liquid storage unit 25 and the first liquid storage unit 12, which can effectively control the amount of aerosol generating device supplied to the atomizing core 111 and reduce the probability of aerosol generating device leaking from the atomizing core 111.

[0088] In some embodiments, the second liquid reservoir 25 is provided only in the fluid channel 20b; in some embodiments, the second liquid reservoir 25 is provided in both the additional storage cavity 20a and the fluid channel 20b.

[0089] The specific form of the second liquid storage component 25 is not limited. For example, it can be a fiber structure woven or twisted from cotton, sponge, polyester, nylon and other chemical fibers, or it can be a porous material such as ceramic.

[0090] The specific method for ensuring that the capillary attraction of the first liquid reservoir 12 to the aerosol generating matrix is ​​not less than that of the second liquid reservoir 25 to the aerosol generating matrix is ​​not limited. For example, the first liquid reservoir 12 and the second liquid reservoir 25 are made of the same material, and the average volume of the pores in the first liquid reservoir 12 is less than the average volume of the pores in the second liquid reservoir 25, so that the capillary attraction of the first liquid reservoir 12 to the aerosol generating matrix is ​​greater than that of the second liquid reservoir 25 to the aerosol generating matrix.

[0091] In some embodiments, see Figure 16 One end of the second liquid storage component 25 along the first direction abuts against the inner wall of the auxiliary storage cavity 20a away from the main storage cavity 10a, and the other end abuts against the first liquid storage component 12.

[0092] Thus, on the one hand, the inner wall of the auxiliary storage chamber 20a away from the main storage chamber 10a and the first liquid storage component 12 together limit the second liquid storage component 25 along the first direction, reducing the probability that the second liquid storage component 25 will move due to factors such as shaking of the aerosol generating device and will no longer be in fluid contact with the first liquid storage component 12; on the other hand, as the aerosol generating matrix in the auxiliary storage chamber 20a is consumed, during the user's use of the aerosol generating device, the second liquid storage component 25 can absorb the aerosol generating matrix remaining at the bottom of the auxiliary storage chamber 20a, improving the utilization rate of the aerosol generating matrix in the auxiliary storage chamber 20a.

[0093] In some embodiments where the fluid channel 20b extends along the first direction, see [reference]. Figure 14 and Figure 15 The second liquid storage element 25 fills the fluid channel 20b.

[0094] In other words, there is no gap between the second liquid storage element 25 and the inner wall of the fluid channel 20b perpendicular to the first direction.

[0095] In this way, all aerosol generating matrix flowing out of the auxiliary storage chamber 20a must pass through the second liquid storage component 25, which helps to limit the amount and replenishment rate of aerosol generating matrix entering the main storage chamber 10a, and reduces the probability that too much or too fast aerosol generating matrix flows into the main storage chamber 10a, causing the first liquid storage component 12 to become oversaturated.

[0096] In some embodiments, see Figure 16 In the projection plane perpendicular to the first direction, the projection of the second liquid storage component 25 is located within the projection range of the fluid channel 20b.

[0097] In this way, on the one hand, it is convenient to install the second liquid storage component 25 into the housing assembly 21 along the first direction during the production and assembly process of the auxiliary oil tank 20; on the other hand, it is beneficial to reduce the space occupied by the second liquid storage component 25 in the auxiliary storage cavity 20a, so that the auxiliary storage cavity 20a can store more aerosol generation matrix and extend its service life.

[0098] Understandably, the atomizer 10 requires an atomizing core 111, which is used to convert the aerosol generating matrix into aerosol and comes into direct contact with the user's mouth, thus having higher hygiene requirements. Therefore, the manufacturing cost of the atomizer 10 is higher than that of the auxiliary oil tank 20.

[0099] In some embodiments, see Figure 10 , Figure 14 and Figure 15 The auxiliary oil tank 20 is provided with a placement hole 21a, which is open on at least one side along the first direction, and at least a portion of the atomizer 10 is located in the placement hole 21a.

[0100] It is understood that the additional storage cavity 20a and the fluid channel 20b are both isolated from the placement hole 21a.

[0101] The inner wall of the placement hole 21a can limit the portion of the atomizer 10 that enters the placement hole 21a.

[0102] By utilizing the placement hole 21a, the housing assembly 21 can protect at least a portion of the atomizer 10, reducing the likelihood of damage to the atomizer 10 due to factors such as impacts during the use of the aerosol generating device.

[0103] In some embodiments, see Figure 4The atomizing component 11 includes an atomizing core 111 and a mounting component 113. The mounting component 113 has a mounting cavity and an air outlet channel 10b. The atomizing core 111 is disposed in the mounting cavity and surrounds the inner wall of the mounting cavity to form a main storage cavity 10a. At least a portion of the atomizing core 111 is located in the placement hole 21a.

[0104] A portion of the surface of the atomizing core 111 forms part of the inner wall of the main storage chamber 10a, so that the aerosol in the main storage chamber 10a can be absorbed by the atomizing core 111, and then the atomizing core 111 converts the aerosol generation matrix into aerosol.

[0105] The atomizer core 111 is located in the placement hole 21a, and the housing assembly 21 can protect at least part of the atomizer 10.

[0106] The placement hole 21a is open on one side to form a first placement port 21b, through which at least a portion of the atomizer 10 can enter the placement hole 21a.

[0107] In some embodiments, see Figure 3 The atomizing core 111 has an atomizing chamber 111a, which is connected to the air outlet channel 10b. The atomizing chamber 111a is isolated from the main storage chamber 10a. The aerosol generated by the atomizing core 111 enters the atomizing chamber 111a and is then discharged to the user's mouth through the air outlet channel 10b.

[0108] In some embodiments provided with a sealing cap 1131 and a mounting housing 1132, see [reference] Figure 3 The mounting assembly 113 includes a sealing cap 1131 and a mounting housing 1132.

[0109] In some embodiments, see Figure 4 The mounting housing 1132 is also provided with a second mounting groove 1132b and a connecting hole 1132c. The second mounting groove 1132b is open along the first direction on the same side as the open position of the first mounting groove 1132a. The sealing cap 1131 is sealed and covers the open position of the second mounting groove 1132b. The atomizing core 111 is located in the second mounting groove 1132b and surrounds the inner wall of the second mounting groove 1132b to form at least a portion of the main storage cavity 10a. The connecting hole 1132c extends along the second direction and connects the first mounting groove 1132a and the second mounting groove 1132b. The connecting hole 1132c forms a part of the main channel 10c.

[0110] Thus, the sealing cap 1131 can simultaneously seal the main storage chamber 10a and the first sub-channel 10ca, which helps to reduce the number of parts and makes the structure of the atomizer 10 more compact.

[0111] In some embodiments, see Figure 4 , Figure 8 , Figure 9 and Figure 10 One of the atomizer 10 and the auxiliary oil tank 20 can contact a part of the other and move that part relative to another part of the other, so that the main storage chamber 10a is connected to or disconnected from the auxiliary storage chamber 20a.

[0112] One of the atomizer 10 and the auxiliary oil tank 20 can come into contact with a portion of the other, thereby creating a power transmission path between the atomizer 10 and the auxiliary storage tank.

[0113] When a user applies a force to at least one of the atomizer 10 or the auxiliary tank 20, one of the atomizer 10 and the auxiliary tank 20, as well as a portion of the other, can move synchronously relative to a portion of the other, allowing a portion of the other to move to at least two different relative positions. When the two are in one of the relative positions, the main storage chamber 10a is connected to the auxiliary storage chamber 20a; when the two are in the other relative position, the main storage chamber 10a is connected to the auxiliary storage chamber 20a, and the aerosol generating matrix can no longer flow from the auxiliary storage chamber 20a into the main storage chamber 10a.

[0114] Thus, the auxiliary oil tank 20 and the atomizer 10 need to cooperate with each other to achieve the movement of one part relative to the other part, so as to connect or disconnect the main storage chamber 10a and the auxiliary storage chamber 20a. This helps to reduce the probability of leakage of the aerosol generation matrix caused by accidental opening of the main storage chamber 10a or the auxiliary storage chamber 20a during the separate packaging and transportation of the auxiliary oil tank 20 or the atomizer 10.

[0115] In some implementations, see [reference] Figure 4 and Figure 10 The auxiliary oil tank 20 includes a sealing movable block 22 and a housing assembly 21. The housing assembly 21 includes a fluid channel 20b and an auxiliary storage chamber 20a. The fluid channel 20b communicates with the outside of the housing assembly 21. The sealing movable block 22 is provided with a through-through transition channel 22a. The atomizer 10 can push the sealing movable block 22 to move relative to the housing assembly 21, so that the auxiliary oil tank 20 switches between a connected state and a sealed state. In the sealed state, the sealing movable block 22 closes the fluid channel 20b. In the connected state, the fluid channel 20b opens, so that the main storage chamber 10a communicates with the auxiliary storage chamber 20a.

[0116] By forming a force transmission path between the atomizer 10 and the sealing movable block 22, the sealing movable block 22 can rotate with the atomizer 10, and thus rotate relative to the housing assembly 21.

[0117] Motion includes translation and rotation.

[0118] Translation refers to the ability of the sealing movable block 22 to move relative to the housing assembly 21 along a certain straight line.

[0119] Rotation refers to the ability of the sealing movable block 22 to rotate relative to the housing assembly 21 around a certain straight line as the center of rotation.

[0120] In the sealed state, the sealing block 22 moves relative to the housing assembly 21 to a first position such that the sealing block 22 covers the opening of the fluid channel 20b for communication with the outside of the housing assembly 21, making it difficult for the aerosol generation matrix to leak from the fluid channel 20b.

[0121] In the connected state, the sealing movable block 22 moves to a second position relative to the housing assembly 21, and the portion of the atomizer 10 located in the transfer channel 22a can communicate with the fluid channel 20b, thereby allowing the aerosol generating matrix in the additional storage chamber 20a to enter the atomizer 10 through the transfer channel 22a.

[0122] In some embodiments, see Figure 4 and Figure 10 The sealing block 22 is located outside the housing assembly 21.

[0123] In some embodiments, a portion of the atomizer 10 can be inserted into the adapter channel 22a through one end opening, thereby allowing a portion of the atomizer 10 to abut against the inner wall of the adapter channel 22a to achieve the purpose of pushing the sealing movable block 22 to move.

[0124] It is understandable that when the auxiliary oil tank 20 is separated from the atomizer 10, the auxiliary oil tank 20 is in a sealed state.

[0125] Understandably, the atomizer 10 cannot enter the fluid channel 20b to avoid the atomizer 10 coming into contact with the inner wall of the fluid channel 20b, which would prevent the sealing movable block 22 from moving relative to the components of the housing.

[0126] Understandably, during the process of the user rotating the atomizer 10 relative to the housing assembly 21, it is necessary to ensure that the user can perceive that the auxiliary oil tank 20 has switched to a sealed state, in order to reduce the risk of leakage of the aerosol generation matrix due to user misoperation.

[0127] Specifically, see Figures 5 to 7 , Figure 10One of the auxiliary oil tank 20 and the atomizer 10 is provided with a slider 213, and the other is provided with a groove 11d and a limiting groove 11e. The groove 11d extends along the through direction of the transfer channel 22a. One end of the groove 11d along the through direction of the transfer channel 22a is open to form an inlet 11g and the other end is connected to the limiting groove 11e. The limiting groove 11e extends along the rotation direction of the sealing movable block 22 and is provided with a limiting surface 11f on one side along the rotation direction of the sealing movable block 22. The slider 213 can enter and exit the groove 11d through the inlet 11g and slide in the groove 11d and the limiting groove 11e. In the connected state, the slider 213 and the limiting surface 11f abut against each other along the rotation direction of the sealing movable block 22.

[0128] During the insertion of a portion of the atomizer 10 into the adapter channel 22a, the slider 213 simultaneously enters the groove 11d through the inlet / outlet 11g and moves along the through direction of the adapter channel 22a until the depth of insertion of the atomizer 10 into the adapter channel 22a meets the preset requirements. Then, the atomizer 10 and the sealing movable block 22 can rotate together, so that the slider 213 rotates synchronously relative to the inner wall of the limiting groove 11e until the slider 213 abuts against the inner wall of the limiting surface 11f along the rotation direction of the sealing movable block 22, so that the atomizer 10 and the sealing movable block 22 can no longer rotate relative to the housing assembly 21. In this way, the user can perceive that the sealing movable block 22 is in a connected state through the force feedback generated by the inability to rotate, and can use the aerosol generating device normally. In the connected state, the slider 213 can cooperate with the inner wall of the limiting groove 11e along the first direction to stop, thereby reducing the probability of separation between the atomizer 10 and the auxiliary oil tank 20 along the first direction.

[0129] It is understood that the slider 213 has two directions of rotation relative to the inner wall of the limiting groove 11e. In some embodiments, at least one of the atomizer 10 and the auxiliary oil tank 20 is provided with a rotation direction indicator pattern so that the user can know the preset direction of rotation of the slider 213 relative to the inner wall of the limiting groove 11e according to the indicator pattern, thereby improving the user experience.

[0130] The number of slide grooves 11d and limiting grooves 11e is the same as the number of sliders 213. The number of sliders 213 can be one or more.

[0131] In some embodiments, see Figure 10 The slide groove 11d and the limiting groove 11e or the slider 213 are provided on the inner wall of the placement hole 21a to reduce the probability that foreign objects will enter the slide groove 11d and the limiting groove 11e, causing the atomizer 10 and the sealing movable block 22 to be unable to rotate relative to each other.

[0132] In some embodiments, the slider 213 is provided with a slot, and the limiting groove 11e is provided with a positioning protrusion. The positioning protrusion forms a limiting surface 11f on one side surface along the rotation direction of the sealing movable block 22. The slider 213 can generate elastic deformation so that the positioning protrusion can be embedded in the slot. In the connected state, the positioning protrusion is embedded in the slot, and the limiting surface 11f abuts against the inner wall of the slot along the rotation direction of the sealing movable block 22.

[0133] This helps to keep the positions of the atomizer 10 and the housing assembly 21 stable along the rotation direction of the sealing movable block 22.

[0134] In some embodiments, see Figure 10 The auxiliary oil tank 20 also includes a cover 23, which covers the outer surface of the housing assembly 21 and forms a limiting space with the housing assembly 21. The fluid channel 20b communicates with the limiting space. The sealing movable block 22 is located in the limiting space. The two ends of the sealing movable block 22 along the through direction of the transition channel 22a respectively cooperate with the cover 23 and the housing assembly 21. The cover 23 is provided with a clearance channel 23a that runs through the through direction of the transition channel 22a. The clearance channel 23a communicates with the outside of the transition channel 22a and the outside of the auxiliary oil tank 20. A part of the atomizer 10 can pass through the clearance channel 23a and be inserted into the transition channel 22a.

[0135] The sealing movable block 22 is located within the limiting space and is sandwiched between the cover 23 and the housing assembly 21, thereby limiting the range of motion of the sealing movable block 22 and reducing the probability of the sealing movable block 22 falling off the housing assembly 21.

[0136] After a portion of the atomizer 10 is inserted into the adapter channel 22a, it can move within the clearance channel 23a. The inner wall of the clearance channel 23a can guide and constrain the movement of the atomizer 10, so that the sealing movable block 22 can move along a predetermined movement path.

[0137] In some embodiments, see Figure 1 , Figure 3 and Figure 11 The aerosol generating device also includes a power supply component 30 that can be electrically connected to the atomizer 10. The power supply component 30 can provide electrical energy to the atomizer 10 so that the atomizer 10 can convert electrical energy into heat energy to convert the aerosol generating matrix into aerosol.

[0138] In some embodiments, see Figure 11The power supply assembly 30 is provided with a receiving groove 30a, which is open on one side along a first direction. The atomizer 10 is provided with an electrical connection area 10i for electrical connection with the power supply assembly 30 on one side end face facing the power supply assembly 30. The inner wall of the receiving groove 30a away from its open position is provided with a power supply area 30b. At least a portion of the atomizer 10 can be inserted into the receiving groove 30a so that the electrical connection area 10i and the power supply area 30b are electrically connected, thereby enabling the power supply assembly 30 to supply power to the atomizer 10.

[0139] The inner wall of the receiving groove 30a helps to separate the electrical connection area 10i and the power supply area 30b from the parts outside the aerosol generating device, reducing the probability of poor contact between the electrical connection area 10i and the power supply area 30b caused by foreign objects.

[0140] In some embodiments where the receiving groove 30a is provided, see [reference]. Figure 3 , Figure 5 and Figure 11 The inner wall of the receiving groove 30a away from its open position is provided with a positioning protrusion 31. The rotation axis 22b of the sealing movable block 22 is along the first direction. At least one of the auxiliary oil tank 20 and the atomizer 10 has a stop end face 10j on one side of the first direction. The stop end face 10j is provided with a positioning groove 10k that is open on one side of the first direction. The aerosol generating device includes an electrically conductive state and an electrically disconnected state. In the electrically conductive state, the positioning protrusion 31 is embedded in the positioning groove 10k and engages with the inner wall of the positioning groove 10k to prevent rotation. In the electrically disconnected state, the stop end face 10j abuts against the positioning protrusion 31 along the first direction.

[0141] It is understandable that the auxiliary oil tank 20 and the atomizer 10, except for the stop end face 10j, will not protrude beyond the stop end face 10j in the first direction.

[0142] After the user inserts the atomizer 10 into the receiving slot 30a, if the positioning protrusion 31 is not aligned with the positioning slot 10k, the electrical connection area 10i and the power supply area 30b cannot make contact because the stop end face 10j abuts against the positioning protrusion 31, and the aerosol generating device is in an electrically disconnected state. This causes a portion of the atomizer 10 to be located outside the receiving slot 30a compared to the electrically conductive state. Furthermore, because the contact area between the positioning protrusion 31 and the stop end face 10j is small, the atomizer 10 is prone to wobbling in the receiving slot 30a perpendicular to the first direction, allowing the user to perceive that the aerosol generating device is currently in an electrically disconnected state. The user rotates the atomizer 10 until the positioning protrusion 31 aligns with the positioning groove 10k, so that the positioning protrusion 31 is embedded in the positioning groove 10k, and the electrical connection area 10i and the power supply area 30b are in contact. The aerosol generating device is in an electrically conductive state, and the inner wall of the positioning groove 10k limits the positioning protrusion 31, so that at least one of the atomizer 10 and the auxiliary oil tank 20 cannot rotate relative to the power supply component 30, so that the user can perceive that the aerosol generating device is currently in an electrically conductive state.

[0143] In some embodiments, see Figure 5 The end face of the auxiliary oil tank 20 along the first direction is the second end face 20f, and the end face of the atomizer 10 along the first direction is the first end face 10e. Both the first end face 10e and the second end face 20f form the stop end face 10j.

[0144] In some embodiments, a portion of the stop end face 10j forms an electrical connection region 10i, and the portion of the inner wall of the receiving groove 30a away from its open position, located outside the positioning protrusion 31, forms a power supply region 30b.

[0145] In some embodiments, see Figure 5 and Figure 7 The positioning groove 10k includes a first positioning sub-groove 20i and a second positioning sub-groove 11h. The auxiliary oil tank 20 is provided with a stop end face 10j and a first positioning sub-groove 20i. The atomizer 10 is provided with a stop end face 10j and a second positioning sub-groove 11h. The first positioning sub-groove 20i and the second positioning sub-groove 11h are both radially open along the rotation axis 22b of the sealing movable block 22 and their opening directions are opposite. In the sealed state, the first positioning sub-groove 20i and the second positioning sub-groove 11h are opposite to each other in their radially open positions along the rotation axis 22b of the sealing movable block 22. In the electrically conductive state, the positioning protrusion 31 is inserted into the first positioning sub-groove 20i and the second positioning sub-groove 11h.

[0146] In the electrically conductive state, part of the positioning protrusion 31 is located in the first positioning sub-groove 20i and part is located in the second positioning sub-groove 11h. In this way, the positioning protrusion simultaneously achieves anti-rotation engagement with the inner wall of the first positioning sub-groove 20i and the inner wall of the second positioning sub-groove 11h, so that a force transmission path is formed among the atomizer 10, the auxiliary oil tank 20 and the positioning protrusion 31. This suppresses the tendency of relative rotation between the atomizer 10 and the auxiliary oil tank 20 in the electrically conductive state, which is beneficial to maintaining the auxiliary oil tank 20 in a connected state while in the electrically conductive state, and is beneficial to maintaining the long-term stable operation of the aerosol generation device.

[0147] In some embodiments, the atomizer 10 is detachably connected to the auxiliary oil tank 20 so that the auxiliary oil tank 20 can be replaced.

[0148] The atomizer 10 and the auxiliary oil tank 20 are detachably connected. The specific method of achieving the detachable connection is not limited. For example, one of the atomizer 10 and the auxiliary oil tank 20 is provided with an elastic buckle, and the other is provided with a disassembly hole. The elastic deformation of the elastic buckle allows it to be inserted into or removed from the disassembly hole.
