Description

Technical Field

[0001] This application relates to the field of atomization technology, and more particularly to an aerosol generating device. Background Technology

[0002] An aerosol generator is an electronic delivery system that uses control circuits and atomizing elements to control its operating status and vapor output for user use.

[0003] The aerosol generator includes an auxiliary fuel tank, an atomizer, and a power supply unit. The power supply unit provides power to the atomizer. To increase the reliability of transporting and storing the auxiliary fuel tank, the aerosol generating matrix inside is isolated from the air and the atomizer before use. When needed, the atomizer moves a portion of the auxiliary fuel tank to connect the aerosol generating matrix with the atomizer, thus enabling atomization. However, in this method, there is a risk that parts of the atomizer and auxiliary fuel tank may move relative to the power supply unit during use, affecting the flow of the aerosol generating matrix and the electrical connection between the atomizer and the power supply unit. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide an aerosol generating device in which the electrical connection is not activated before use, thereby improving safety performance, and the movement of the atomizer is restricted by the power supply component during use, resulting in high reliability of atomization and electrical connection.

[0005] This application provides an aerosol generating apparatus, comprising:

[0006] An additional oil tank has at least one additional storage cavity for storing the aerosol generation matrix and has a first positioning structure;

[0007] An atomizer includes an atomizing core and a conductive element electrically connected to the atomizing core, and has a second positioning structure; the atomizer is movable relative to the additional storage chamber so that the additional oil tank switches between an open state and a closed state;

[0008] Power supply assembly, including power supply components and stop structure;

[0009] When the auxiliary oil tank is in the open state, the auxiliary storage cavity is in fluid communication with the atomizing core, the conductive element is electrically connected to the power supply element, and both the first positioning structure and the second positioning structure are connected to the stop structure to restrict the auxiliary oil tank from switching to the closed state; when the auxiliary oil tank is in the closed state, the fluid path between the auxiliary storage cavity and the atomizing core is disconnected, the conductive element is separated from the power supply element, and the stop structure is misaligned with at least one of the first positioning structure and the second positioning structure.

[0010] In some embodiments, the entire auxiliary oil tank is detachably connected to the atomizer along a first direction; and / or, the entire power supply assembly is detachably connected to the atomizer and the entire auxiliary oil tank along a first direction, wherein the first direction is parallel to the axial direction of the atomizer.

[0011] In some embodiments, the first positioning structure includes a first positioning sub-groove formed in the auxiliary oil tank along the axial direction of the atomizer and toward one end of the power assembly; the second positioning structure includes a second positioning sub-groove formed in the atomizer along the axial direction and toward one end of the power assembly; the stop structure includes a positioning protrusion formed in the power assembly;

[0012] When the auxiliary oil tank is in the open state, the first positioning sub-slot and the second positioning sub-slot are aligned along the second direction to form the mounting structure, and the positioning protrusion is inserted into the mounting structure.

[0013] When the auxiliary oil tank is in the closed state, the first positioning sub-slot and the second positioning sub-slot are isolated from each other, and the positioning protrusion is misaligned with at least one of the first positioning sub-slot and the second positioning sub-slot;

[0014] The second direction is perpendicular to the axial direction of the atomizer.

[0015] In some implementations, the atomizer's axially facing side end face toward the power assembly is flush with the auxiliary oil tank's axially facing side end face toward the power assembly.

[0016] In some embodiments, the conductive element includes at least one electrical connection region, the atomizing core is electrically connected to the electrical connection region, the electrical connection region is disposed on the side of the atomizing core facing the power assembly, and exposed on the end face of the atomizer facing the power assembly;

[0017] The power supply component includes at least one power supply area, the end face of the power supply area facing the atomizer is flush with the end face of the positioning protrusion facing the atomizer, and when the auxiliary oil tank is in the open state, the electrical connection area is in electrical contact with the power supply area.

[0018] In some implementations, there are two of each of the first positioning sub-slot, the second positioning sub-slot, and the positioning protrusion. The two mounting structures are arranged opposite each other along the second direction. In the open state, the electrical connection area is located between the two mounting structures.

[0019] In some embodiments, the additional oil tank has an inner wall and an outer wall, the space between the inner wall and the outer wall defining at least the additional storage cavity, the inner wall defining a placement slot through which the atomizer passes.

[0020] In some embodiments, the placement slot is provided with at least one protruding structure, the protruding structure forming a slot, and the outer periphery of the atomizer is formed with an annular groove and a snap-fit ​​structure, the snap-fit ​​structure protruding from the annular groove;

[0021] When the auxiliary oil tank is in the closed state, the snap-fit ​​structure and the protruding structure are spaced apart along the circumference of the atomizer;

[0022] When the auxiliary oil tank is in the open state, the snap-fit ​​structure snaps into the slot.

[0023] In some embodiments, the atomizer has a clearance area formed on its outer periphery. The clearance area is located on the bottom side of the annular groove and communicates with the annular groove. When the atomizer and the auxiliary oil tank are aligned in a first direction, the clearance area avoids the protruding structure to guide the protruding structure to the annular groove. When the auxiliary oil tank is in the open state, the clearance area cooperates with the annular groove to restrict the separation of the atomizer and the auxiliary oil tank in the first direction, wherein the first direction is parallel to the axial direction of the atomizer.

[0024] In some embodiments, the atomizer has a main channel, a main storage chamber, and an atomizing chamber. The main storage chamber is used to store an aerosol generation matrix. The main channel is used to guide the aerosol generation matrix from the auxiliary storage chamber to the main storage chamber when the auxiliary oil tank is in the open state. The main storage chamber is connected to the atomizing chamber, and the atomizing core is disposed in the atomizing chamber.

[0025] The aerosol generating device provided in this application embodiment, when the auxiliary oil tank is in a closed state, on the one hand, the fluid path between the auxiliary storage chamber and the atomizing core is disconnected, and the auxiliary storage chamber is in a closed state, isolating the aerosol generating matrix in the auxiliary storage chamber from the air and the atomizer, reducing the probability of leakage, and facilitating transportation and storage when not in use. On the other hand, the stop structure is misaligned with at least one of the first positioning structure and the second positioning structure, and the power supply component on the power assembly is separated from the conductive component on the atomizer, that is, electrical connection cannot be achieved. Thus, accurate docking of the power assembly and the atomizer cannot be achieved, making... When the atomizer is in the closed state, the electrical connection will not be activated, reducing unnecessary power consumption and improving safety performance. When the auxiliary oil tank is in the open state, the movement of the atomizer connects the atomizer to the auxiliary storage chamber. The stop structure simultaneously engages with the first and second positioning structures. While assembling with the power supply component and electrically connecting the atomizer to the power supply component, the power supply component can also restrict the relative movement of the atomizer, thereby limiting the switching of the auxiliary oil tank to the closed state, reducing the risk of accidental movement of the atomizer, and ensuring that the position of the atomizer is fixed during atomization, without affecting atomization and the reliability of the electrical connection.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0044] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0045] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0046] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0047] This application provides an aerosol generating device 1.

[0048] It should be noted that the specific type of aerosol generating device 1 provided in the embodiments of this application is not limited. For example, aerosol generating device 1 can be a medical atomizing device, an air humidifier, or an atomizing device such as an electronic cigarette.

[0049] Please see Figures 1 to 12 The aerosol generating device 1 includes an auxiliary oil tank 10, an atomizer 11, and a power supply assembly 12.

[0050] The auxiliary oil tank 10 is used to store the aerosol generating matrix, the atomizer 11 is used to heat and atomize the aerosol generating matrix after being powered on, and the power supply component 12 is mainly used to power the atomizer 11 and control the opening and closing of the entire aerosol generating device 1. The aerosol generating matrix includes, but is not limited to, materials used for medical, health, and beauty purposes.

[0051] The auxiliary oil tank 10 has at least one auxiliary storage cavity 101a for storing the aerosol generation matrix and has a first positioning structure.

[0052] The atomizer 11 includes an atomizing core and a conductive element electrically connected to the atomizing core, and has a second positioning structure. The atomizer 11 is movable relative to the auxiliary storage chamber 101a, so that the auxiliary oil tank 10 can be switched between an open state and a closed state.

[0053] The power supply assembly 12 includes a power supply component and a stop structure.

[0054] When the auxiliary oil tank 10 is in the open state, the auxiliary storage chamber 101a is in fluid communication with the atomizing core, the conductive component is electrically connected to the power supply component, and the first positioning structure and the second positioning structure are both connected to the stop structure to restrict the auxiliary oil tank 10 from switching to the closed state.

[0055] When the auxiliary oil tank 10 is in the closed state, the fluid path between the auxiliary storage chamber 101a and the atomizing core is disconnected, the conductive component is separated from the power supply component, and the stop structure is misaligned with at least one of the first positioning structure and the second positioning structure.

[0056] Here, "at least one" can refer to one or more, and "multiple" can refer to two or more. That is, the number of additional storage cavities 101a can be one, two, or more. It is understood that when there are multiple additional storage cavities 101a, the additional storage cavities 101a are not interconnected, that is, there will be no liquid mixing, thus increasing the storage reliability of the aerosol generation matrix.

[0057] The atomizer 11 is able to move relative to the auxiliary storage chamber 101a, which means that there is relative movement between the atomizer 11 and the auxiliary storage chamber 101a. Here, the movement can include sliding, rotation, etc.

[0058] It is understandable that the atomizer 11 can move as a whole relative to the auxiliary oil tank 10. In this case, the atomizer 11 can switch the auxiliary oil tank 10 between the open and closed states through its own structure. Alternatively, the atomizer 11 can move relative to a part of the auxiliary oil tank 10 (including the auxiliary storage chamber 101a). In this case, the atomizer 11 can be connected to another part of the auxiliary oil tank 10 and drive it to rotate relative to that part of the auxiliary oil tank 10, thereby allowing the auxiliary oil tank 10 to switch between the open and closed states.

[0059] For example, the atomizer 11 can switch the auxiliary oil tank 10 between an open and closed state by moving the sealing movable block 102 relative to the auxiliary storage chamber 101a. The sealing movable block 102 can be disposed in the atomizer 11 or in the auxiliary oil tank 10.

[0060] In some embodiments, the auxiliary oil tank 10 includes a housing assembly 101 and a sealing movable block 102. The housing assembly 101 at least defines an auxiliary storage cavity 101a. The sealing movable block 102 is movably connected to the housing assembly 101. The atomizer 11 is connected to the sealing movable block 102 and can drive the sealing movable block 102 to move relative to the housing assembly 101. This allows the auxiliary oil tank 10 to switch between an open state and a closed state.

[0061] For example, the sealing movable block 102 is provided with a transfer channel 102a; in the open state, the aerosol generation matrix is ​​guided to the atomizing core through the flow between the transfer channel 102a and the additional storage chamber 101a; in the closed state, the transfer channel 102a is disconnected from the additional storage chamber 101a, the sealing movable block 102 closes the additional storage chamber 101a, and the fluid path between the additional storage chamber 101a and the atomizing core is disconnected.

[0062] It is understandable that the atomizer 11 can be connected to the sealing movable block 102 through the adapter channel 102a, that is, part of the atomizer 11 is inserted into the adapter channel 102a. Of course, the atomizer 11 can also be connected to the sealing movable block 102 in other ways. In this case, the adapter channel 102a can only be used for the flow of aerosol generation matrix.

[0063] Here, an external force can be used to drive the atomizer 11, which in turn drives the sealing block 102 to move relative to the housing assembly 101. The external force can be a manual operating force or an operating force applied by a tool.

[0064] When the auxiliary oil tank 10 is in the open state, the auxiliary storage chamber 101a is in fluid communication with the atomizing core. This means that the atomizer 11 can move relative to the auxiliary storage chamber 101a until the auxiliary storage chamber 101a is in communication with the atomizing core, and the aerosol generating matrix in the auxiliary storage chamber 101a can flow to the atomizing core. The conductive component is electrically connected to the power supply component, meaning that the power supply component can provide electrical energy to the conductive component through the power supply component, so that the atomizing core can obtain electrical energy from the conductive component to atomize the aerosol generating matrix. Both the first positioning structure and the second positioning structure are connected to the stop structure, meaning that the stop structure simultaneously cooperates with both the first and second positioning structures. Here, the stop structure can be a whole formed by cooperating with the first and second positioning structures, or it can be connected separately to the first and second positioning structures, without any cooperation between the first and second positioning structures. In other words, in the open state, the first and second positioning structures are in the correct docking position. In this position, the stop structure can simultaneously cooperate with both the first and second positioning structures, preventing the auxiliary oil tank 10 from switching to the closed state. Thus, with the cooperation of the stop structure, the first positioning structure and the second positioning structure, the relative position of the atomizer 11 is determined, so that the atomizer 11 will not move unnecessarily relative to the additional storage cavity 101a when it is in the open state, and the conductive parts and the power supply parts can always maintain an electrical connection, increasing the reliability of atomization and the reliability of electrical connection.

[0065] It is understandable that the stop structure can be a structure that can cooperate with both the first positioning structure and the second positioning structure at the same time, or it can include two structures, one of which cooperates with the first positioning structure and the other of which cooperates with the second positioning structure. No restrictions are imposed here.

[0066] When the auxiliary oil tank 10 is in the closed state, the fluid path between the auxiliary storage chamber 101a and the atomizer core is disconnected. This means that the auxiliary storage chamber 101a and the atomizer core are disconnected, and the auxiliary storage chamber 101 can be in a closed state. The aerosol generating matrix in the auxiliary storage chamber 101a is isolated from the air and the atomizer 11. The conductive component and the power supply component are separated, meaning that the conductive component and the power supply component are not electrically connected, and the power supply assembly 12 does not provide power to the atomizer core. The stop structure is misaligned with at least one of the first positioning structure and the second positioning structure. This means that the stop structure is in an incorrect docking position with at least one of the first positioning structure and the second positioning structure, and cannot be matched. Here, the stop structure may be misaligned with one of the first positioning structure and the second positioning structure. In this case, the stop structure may be in the correct docking position with one of the first positioning structure and the second positioning structure, while the other is in the incorrect docking position. Thus, the connection cannot be achieved due to the misalignment. Alternatively, the stop structure may be misaligned with both the first positioning structure and the second positioning structure. In this case, the stop structure cannot be correctly matched with either the first positioning structure or the second positioning structure, meaning that the connection between the power supply assembly 12 and the atomizer 11 and the auxiliary oil tank 10 cannot be achieved.

[0067] The aerosol generating device 1 provided in this application embodiment, when the auxiliary oil tank 10 is in the closed state, on the one hand, the fluid path between the auxiliary storage chamber and the atomizing core is disconnected, and the auxiliary storage chamber 101a is in a closed state, isolating the aerosol generating matrix in the auxiliary oil tank 10 from the air and the atomizer 11, reducing the probability of leakage, and facilitating transportation and storage when not in use. On the other hand, the stop structure is misaligned with at least one of the first positioning structure and the second positioning structure, and the power supply component on the power assembly 12 is separated from the conductive component on the atomizer 11, that is, electrical connection cannot be achieved. Thus, accurate docking of the power assembly 12 and the atomizer 11 cannot be achieved, making it impossible to close the device. In this state, the electrical connection will not be activated, reducing unnecessary power consumption and improving safety performance. When the auxiliary oil tank 10 is in the open state, the movement of the atomizer 11 connects the atomizer 11 to the auxiliary storage chamber 101a. The stop structure, along with the first positioning structure and the second positioning structure, cooperate to dock. While realizing the assembly with the power component 12 and the electrical connection between the atomizer 11 and the power component 12, the power component 12 can also restrict the relative movement of the atomizer 11, thereby restricting the auxiliary oil tank 10 from switching to the closed state, reducing the risk of accidental movement of the atomizer 11, and ensuring that the position of the atomizer 11 is fixed during atomization, without affecting atomization and the reliability of the electrical connection.

[0068] In some embodiments, please refer to Figure 5 and Figure 6The auxiliary oil tank 10 is detachably connected to the atomizer 11 along a first direction, which is parallel to the axis of the atomizer 11.

[0069] Specifically, the auxiliary oil tank 10 is detachably connected to the atomizer 11. When the atomizer 11 and the auxiliary oil tank 10 are connected, the connection is secure and not easily loosened or detached. When it is necessary to separate the atomizer 11 from the auxiliary oil tank 10, the connection between the atomizer 11 and the auxiliary oil tank 10 can be released without disassembling the internal structure of the auxiliary oil tank 10.

[0070] The detachable connection method is not limited; it can be a plug-in connection, etc., meaning that installation and disassembly can be achieved through simple operations. Connecting along the first direction reduces the circumferential size of the aerosol generating device 1, making it easier for the user to hold. For example, the first direction can be... Figure 1 The top and bottom directions of the structure shown.

[0071] In some embodiments, please refer to Figure 3 The power supply assembly 12 is detachably connected to the atomizer 11 and the auxiliary oil tank 10 along the first direction.

[0072] In other words, after the atomizer 11 and the auxiliary oil tank 10 are connected and the first positioning structure and the second positioning structure are aligned, the power assembly 12 is then connected to the atomizer 11 and the auxiliary oil tank 10 as a whole. Users can easily replace the power assembly 12 to facilitate charging or battery replacement, thereby improving the portability and battery life of the aerosol generating device 1.

[0073] In this embodiment, the modular design allows each module to be tested and repaired individually, increasing the ease of use and flexibility of the aerosol generating device 1.

[0074] In the embodiment where the atomizer 11 and the auxiliary oil tank 10 are detachably connected along the first direction, the atomizer 11 and the auxiliary oil tank 10 as a whole are detachably connected to the power supply assembly 12 along the first direction. The consistent connection direction can facilitate improved assembly efficiency.

[0075] Of course, in other embodiments, the docking direction of the atomizer 11 and the auxiliary oil tank 10 is not the same as the docking direction of the atomizer 11 and the auxiliary oil tank 10 as a whole with the power assembly 12.

[0076] The specific construction of the first positioning structure, the second positioning structure, and the stop structure is not limited.

[0077] In some embodiments, please refer to Figure 3 and Figure 4The first positioning structure includes a first positioning sub-groove 101b formed on the auxiliary oil tank 10 along the axial direction of the atomizer 11 and toward the power assembly 12, the second positioning structure includes a second positioning sub-groove 11c formed on the atomizer 11 along the axial direction toward the power assembly 12, and the stop structure includes a positioning protrusion 121 formed on the power assembly 12.

[0078] When the auxiliary oil tank 10 is in the open state, the first positioning sub-slot 101b and the second positioning sub-slot 11c align along the second direction to form the mounting structure 1a, and the positioning protrusion 121 is inserted into the mounting structure 1a. In other words, in this embodiment, the first positioning structure and the second positioning structure are mutually compatible, and the stop structure aligns with the entire assembly formed by the first and second positioning structures. Specifically, the positioning protrusion 121 aligns with the mounting structure 1a formed by the first positioning sub-slot 101b and the second positioning sub-slot 11c.

[0079] When the auxiliary oil tank 10 is closed, the first positioning sub-slot 101b and the second positioning sub-slot 11c are isolated from each other, and the positioning protrusion 121 is misaligned with at least one of the first positioning sub-slot 101b and the second positioning sub-slot 11c.

[0080] The second direction is perpendicular to the axial direction of the atomizer 11.

[0081] Specifically, in the closed state, the first positioning sub-slot 101b and the second positioning sub-slot 11c are misaligned. At this time, the positioning protrusion 121 can be inserted into one of the first positioning sub-slot 101b and the second positioning sub-slot 11c, or the positioning protrusion 121 cannot be inserted into the first positioning sub-slot 101b and the second positioning sub-slot 11c, and the power supply component and the conductive component cannot be electrically connected. In the open state, the opening of the first positioning sub-slot 101b along the second direction communicates with the opening of the second positioning sub-slot 11c along the second direction to realize the docking of the first positioning sub-slot 101b and the second positioning sub-slot 11c. The first positioning sub-slot 101b and the second positioning sub-slot 11c are aligned to form the mounting structure 1a. At this time, the positioning protrusion 121 can be inserted into the mounting structure 1a to realize the installation of the power supply component 12 and the electrical connection of the power supply component and the conductive component.

[0082] In this embodiment, the first positioning sub-slot 101b and the second positioning sub-slot 11c are engaged with the stop structure in the open state, which facilitates accurate judgment of whether the first positioning sub-slot 101b and the second positioning sub-slot 11c are in the correct engagement position, increasing the ease of engagement. Furthermore, the engagement of the first positioning sub-slot 101b, the second positioning sub-slot 11c and the positioning protrusion 121 is simple in structure, can constrain the movement of the atomizer 11, and increase the structural reliability of the aerosol generating device 1. At the same time, the first positioning sub-slot 101b and the second positioning sub-slot 11c can reduce the manufacturing difficulty of the atomizer 11 and the auxiliary oil tank 10.

[0083] In some embodiments, please refer to Figure 3 The atomizer 11 is flush with the side of the power supply assembly 12 along the axial direction of the atomizer 11 and the side of the auxiliary oil tank 10 along the axial direction of the atomizer 11 and towards the power supply assembly 12.

[0084] In other words, there is no height difference between the end face of the atomizer 11 facing the power supply assembly 12 along the axial direction and the end face of the auxiliary oil tank 10 facing the power supply assembly 12 along the axial direction of the atomizer 11. On the one hand, this makes it easier to ensure that there is no height difference between the first positioning sub-slot 101b and the second positioning sub-slot 11c, which is beneficial to achieve precise alignment of the first positioning sub-slot 101b and the second positioning sub-slot 11c, thereby achieving stable docking with the positioning protrusion 121 and increasing the overall docking reliability of the power supply assembly 12, the auxiliary oil tank 10, and the atomizer 11. On the other hand, the overlapping dimensions of the atomizer 11 and the auxiliary oil tank 10 along the axial direction of the atomizer 11 can reduce the overall size of the aerosol generating device 1 along the axial direction of the atomizer 11 and increase the structural compactness of the aerosol generating device 1.

[0085] Of course, in other embodiments, the side end face of the atomizer 11 facing the power supply assembly 12 along the axial direction and the side end face of the auxiliary oil tank 10 facing the power supply assembly 12 along the axial direction of the atomizer 11 may not be flush with each other, that is, there is a height difference. In this way, the structural restrictions on the atomizer 11 and the auxiliary oil tank 10 can be reduced, and the manufacturing difficulty can be reduced.

[0086] In some embodiments, please refer to Figure 2 The conductive element includes at least one electrical connection area 111, the atomizing core is electrically connected to the electrical connection area 111, the electrical connection area 111 is disposed on the side of the atomizing core facing the power assembly 12, and exposed on the side end face of the atomizer 11 facing the power assembly 12.

[0087] Specifically, the atomizer 11 is connected to the power supply unit through a conductive component to obtain electrical energy, thereby providing electrical energy to the atomizing core. The atomizing core then atomizes the aerosol generation matrix to generate aerosol for user use.

[0088] The specific structure of the atomizing core is not limited. The atomizing core can be a vibration atomization structure or a resistance atomization structure. There are no restrictions here.

[0089] The electrical connection area 111 is exposed on the side end face of the atomizer 11 facing the power assembly 12. This means that the electrical connection area 111 can be seen when viewed from the side end face of the atomizer 11 facing the power assembly 12. Here, the electrical connection area 111 can be protruding from the side end face of the atomizer 11 facing the power assembly 12, or it can be flush with the side end face of the atomizer 11 facing the power assembly 12, or it can be recessed into the side end face of the atomizer 11 facing the power assembly 12. There is no limitation here.

[0090] For example, please refer to Figure 3 The side face of the electrical connection area 111 facing the power supply assembly 12 is flush with the side face of the atomizer 11 facing the power supply assembly 12.

[0091] Please see Figure 4 The power supply component includes at least one power supply area 122, the end face of the power supply area 122 facing the atomizer 11 is flush with the end face of the positioning protrusion 121 facing the atomizer 11, and when the auxiliary oil tank is in the open state, the electrical connection area 111 is in electrical contact with the power supply area 122.

[0092] Specifically, the power supply area 122 and the positioning protrusion 121 are both located at the end of the power supply assembly 12 facing the atomizer 11. The flush arrangement of the power supply area 122 and the positioning protrusion 121 facilitates the confirmation of the position of the power supply area 122 and also facilitates the stable connection between the power supply area 122 and the electrical connection area 111. Specifically, when the positioning protrusion 121 aligns with the mounting structure 1a formed by the first positioning sub-groove 101b and the second positioning sub-groove 11c, the positioning protrusion 121 is inserted into the mounting structure 1a. If the end face of the electrical connection area 111 facing the power supply component 12 is flush with or protrudes from the end face of the atomizer 11 facing the power supply component 12, then no gap will be generated between the electrical connection area 111 and the power supply area 122 when the positioning protrusion 121 aligns with the mounting structure 1a, thus achieving a relatively stable electrical connection. If the end face of the electrical connection area 111 facing the power supply component 12 is recessed into the end face of the atomizer 11 facing the power supply component 12, the structure of the atomizer 11 can also limit the power supply area 122, increasing the stability of the electrical contact.

[0093] The number of power supply areas 122 and electrical connection areas 111 is not limited. For example, there are two power supply areas 122, one for positive power supply and one for negative power supply. There are also two electrical connection areas 111, one for positive electrical connection and one for negative electrical connection. The positive power supply area and the positive electrical connection area are in electrical contact, and the negative power supply area and the negative electrical connection area are in electrical contact. The form of the power supply areas 122 and the electrical connection areas 111 is not limited and can be structures such as spring pins. No limitation is made here.

[0094] In some embodiments, please refer to Figures 2 to 4 The number of the first positioning sub-slot 101b, the second positioning sub-slot 11c, and the positioning protrusion 121 are all two. The two mounting structures 1a are arranged opposite each other along the second direction. When the auxiliary oil tank 10 is in the open state, the electrical connection area 111 is located between the two mounting structures 1a.

[0095] In this embodiment, the cooperation of the two mounting structures 1a and the two positioning protrusions 121 can further increase the stability of the overall docking between the power supply assembly 12, the auxiliary oil tank 10, and the atomizer 11, and increase the reliability of the electrical connection. The power supply area 122 is located between the two positioning protrusions 121. In the open state, the electrical connection area 111 is located between the two mounting structures 1a, which facilitates setting the electrical connection between the power supply area 122 and the electrical connection area 111 between the two positioning protrusions 121 and the two mounting structures 1a. The electrical connection area 111 can be set in the middle area of ​​the atomizer 11, and the power supply area 122 can also be set in the middle area of ​​the power supply assembly 12, reducing the risk of damage to the electrical connection area 111 and the power supply area 122, and increasing the reliability of the layout.

[0096] In some embodiments, please refer to Figure 2 and Figure 5 The auxiliary oil tank 10 has an inner wall 101c and an outer wall 101d. The space between the inner wall 101c and the outer wall 101d defines at least an auxiliary storage cavity 101a. The inner wall 101c defines a placement slot 101f, through which the atomizer 11 passes.

[0097] In this embodiment, the space between the inner wall 101c and the outer wall 101d at least defines the placement groove 101f, which increases the sealing of the additional storage cavity 101a. In the closed state, the design of the additional storage cavity 101a can effectively reduce leakage of the aerosol generation matrix during storage and transportation. The inner wall 101c defines the placement groove 101f, which is not connected to the additional storage cavity 101a. The placement groove 101f is defined by the structure of the inner wall 101c itself to accommodate part of the atomizer 11 structure, reduce the axial dimension of the aerosol generation device 1 along the atomizer 11, and increase the layout compactness.

[0098] For example, an inner wall 101c and an outer wall 101d are formed on the housing assembly 101.

[0099] In some embodiments, please refer to Figures 8 to 10 The placement slot 101f forms a semi-enclosed structure.

[0100] In other words, the inner wall 101c partially wraps around the outer periphery of the part of the atomizer 11 that passes through the placement groove 101f. The semi-enclosed structure has a certain degree of openness, which facilitates observation and maintenance. At the same time, it reduces the overall size and weight of the aerosol generating device 1.

[0101] In other embodiments, please refer to Figure 5 , Figure 11 and Figure 12 The placement groove 101f forms a fully enclosed structure, and the inner wall 101c wraps around the outer periphery of the part of the atomizer 11 that passes through the placement groove 101f.

[0102] In other words, the inner wall 101c completely covers the outer periphery of the part of the atomizer 11 that passes through the placement slot 101f, thereby increasing the docking stability between the atomizer 11 and the auxiliary oil tank 10 and reducing loosening caused by vibration or external force.

[0103] In some embodiments, the placement slot 101f is provided with at least one protruding structure 1011, the protruding structure 1011 forming a slot 1011a, the outer periphery of the atomizer 11 forming an annular groove 11d and a snap-fit ​​structure 112, the snap-fit ​​structure 112 protruding from the annular groove 11d, when the auxiliary oil tank 10 is in the closed state, the snap-fit ​​structure 112 and the protruding structure 1011 are spaced apart along the circumference of the atomizer 11, when the auxiliary oil tank 10 is in the open state, the snap-fit ​​structure 112 snaps into the slot 1011a.

[0104] Specifically, in the closed state, the locking structure 112 and the protruding structure 1011 are spaced apart along the circumference of the atomizer 11, that is, the locking structure 112 and the protruding structure 1011 do not contact each other and are staggered. When it is necessary to switch from the closed state to the open state, the atomizer 11 moves relative to the additional storage chamber 101a, and the locking structure 112 also moves relative to the protruding structure 1011. When the locking structure 112 moves to the point of engaging in the slot 1011a, it indicates that the movement is in place.

[0105] In this embodiment, by cooperating with the snap-fit ​​structure 112 and the protruding structure 1011, when switching from the closed state to the open state, the snap-fit ​​structure 112 and the slot 1011a are successfully docked, indicating that the movement has reached the correct position and that the switch to the open state has been successful. This reduces the possibility of excessive or insufficient movement and further increases the ease of operation.

[0106] In some embodiments, please refer to Figure 5 and Figure 6 An avoidance area 11e is formed on the outer periphery of the atomizer 11. The avoidance area 11e is disposed on the bottom side of the annular groove 11d and communicates with the annular groove 11d. When the atomizer 11 and the auxiliary oil tank 10 are connected in the first direction, the avoidance area 11e avoids the protruding structure 1011 to guide the protruding structure 1011 to the annular groove 11d. When the auxiliary oil tank 10 is in the open state, the avoidance area 11e cooperates with the annular groove 11d to restrict the separation of the atomizer 11 and the auxiliary oil tank 10 in the first direction.

[0107] In this embodiment, the setting of the avoidance area 11e reduces the probability of rubbing against the protruding structure 1011 when the atomizer 11 docks with the auxiliary oil tank 10. Furthermore, it provides a channel for the protruding structure 1011, allowing it to dock along the avoidance area 11e to the annular groove 11d, thus facilitating the docking of the protruding structure 1011 with the snap-fit ​​structure 112 and increasing the structural reliability of the aerosol generating device 1. Moreover, when the protruding structure 1011 successfully docks with the snap-fit ​​structure 112 and switches to the open state, the avoidance area 11e is misaligned with the protruding structure 1011. The annular groove 11d and the avoidance area 11e also restrict the separation of the atomizer 11 and the auxiliary oil tank 10, further limiting their relative displacement in the open state.

[0108] In some embodiments, the atomizer 11 has a main channel 11a, a main storage chamber 11b, and an atomizing chamber. The main storage chamber 11b is used to store the aerosol generation matrix. The main channel 11a is used to guide the aerosol generation matrix in the auxiliary storage chamber 101a to the main storage chamber 11b when the auxiliary oil tank 10 is in the open state. The main storage chamber 11b is connected to the atomizing chamber, and the atomizing core is disposed in the atomizing chamber.

[0109] In other words, when the atomizer 11 is not in contact with the auxiliary storage chamber 101a, the main storage chamber 11b already contains aerosol generation matrix. When atomization is required, the atomizer 11 moves to open the auxiliary oil tank 10. The aerosol generation matrix stored in the main storage chamber 11b can reduce the chance of the atomizer core burning out. At the same time, during this process, the aerosol generation matrix in the auxiliary storage chamber 101a flows to the main storage chamber 11b, which can replenish the aerosol generation matrix, so that the atomizer core can atomize the aerosol generation matrix in the atomization chamber and improve the atomization uniformity.

[0110] Taking the sealing movable block 102 disposed on the housing assembly 101, and the atomizer 11 driving the sealing movable block 102 to rotate as an example, in some embodiments, please refer to... Figure 7The housing assembly 101 has an annular groove 101g formed at one end along the axial direction of the atomizer 11 and away from the power supply assembly 12. The sealing movable block 102 is disposed in the annular groove 101g. The transition channel 102a passes through the annular groove 101g in a first direction. The auxiliary oil tank 10 also includes a cover 103. The cover 103 is disposed on the side of the housing assembly 101 along the axial direction of the atomizer 11 and away from the power supply assembly 12. The transition channel 102a is exposed on the outer surface of the cover 103. A portion of the atomizer 11 is fitted around the outer periphery of the cover 103.

[0111] Specifically, the annular groove 101g provides installation space for the sealing movable block 102, while also not affecting the rotation of the sealing movable block 102. The auxiliary storage chamber 101a is located on the side of the annular groove 101g away from the cover 103, and the transition channel 102a is exposed on the outer surface of the cover 103. That is, the cover 103 can confirm the position of the sealing movable block 102 along the first direction, reducing the probability of the sealing movable block 102 falling out of the annular groove 101g. The cover 103 does not affect the docking of the transition channel 102a with the atomizer 11, facilitating the rotation of the sealing movable block 102 by the atomizer 11 through the transition channel 102a, and enabling communication with the auxiliary storage chamber 101a through the transition channel 102a. Part of the atomizer 11 is fitted around the outer periphery of the cover 103, which allows the cover 103 to be hidden during docking and increases the docking stability with the auxiliary oil tank 10.

[0112] The cover 103 has a first anti-rotation structure, and the housing assembly 101 has a second anti-rotation structure. The first anti-rotation structure and the second anti-rotation structure cooperate to achieve an anti-rotation cooperation between the cover 103 and the housing assembly 101.

[0113] Here, the first anti-rotation structure and the second anti-rotation structure are set so that when the atomizer 11 and the sealing movable block 102 are rotated by external force, there will be no unnecessary relative rotation between the housing assembly 101 and the cover 103. This prevents the cover 103 and the housing assembly 101 from rotating and shifting due to external force, increases the overall structural reliability of the aerosol generating device 1, and facilitates the docking of the transfer channel 102a and the additional storage chamber 101a.

[0114] The specific construction of the first anti-rotation structure and the second anti-rotation structure is not limited. The first anti-rotation structure can be a protrusion, groove or other form of mechanical limiting structure provided on the cover 103, and the second anti-rotation structure can be a groove, protrusion or other form of mechanical limiting structure provided on the housing assembly 101.

[0115] For example, in some embodiments, please refer to Figure 5 and Figure 7The first anti-rotation structure includes a fixing groove 103a formed in the cover 103, and the second anti-rotation structure includes a locking block 1012 formed on the outer peripheral surface of the housing assembly 101, the locking block 1012 being engaged in the fixing groove 103a.

[0116] In this embodiment, the engagement of the locking block 1012 and the fixing groove 103a enables the anti-rotation engagement of the housing assembly 101 and the cover 103 in the circumferential direction. The structure of the locking block 1012 and the fixing groove 103a is simple. While ensuring that the housing assembly 101 and the cover 103 will not rotate or shift due to external forces, it can also circumferentially position the housing assembly 101 and the cover 103, thereby increasing the structural stability of the aerosol generating device 1.

[0117] In some embodiments, please refer to Figure 7 The auxiliary oil tank 10 includes an annular cover 104, which is disposed between the inner wall 101c and the outer wall 101d, and divides the space between the inner wall 101c and the outer wall 101d along a first direction into an auxiliary storage cavity 101a and an annular groove 101g. The annular cover 104 forms a fluid channel 104a, which communicates with the auxiliary storage cavity 101a. A sealing movable block 102 is disposed on the side of the annular cover 104 away from the auxiliary storage cavity 101a. In the closed state, the transfer channel 102a is disconnected from the fluid channel 104a; in the open state, the fluid channel 104a connects the transfer channel 102a with the auxiliary storage cavity 101a.

[0118] Please refer to Figure 2 The housing assembly 101 has at least one limiting rib 1013, which is disposed in the additional storage cavity 101a. The ring cover 104 abuts against the limiting rib 1013, and at least two limiting blocks 1041 are formed on the side of the ring cover 104 facing the additional storage cavity 101a. The limiting rib 1013 is sandwiched between the two limiting blocks 1041 to restrict the relative rotation between the housing assembly 101 and the ring cover 104.

[0119] In this embodiment, the space between the inner wall 101c and the outer wall 101d of the housing assembly 101 is divided into an additional storage cavity 101a and an annular groove 101g by the ring cover 104. In the open state, the additional storage cavity 101a and the liquid guiding channel 11a are connected through the fluid channel 104a and the transfer channel 102a. The limiting rib 1013 can position the ring cover 104 and provide support for the ring cover 104. The cooperation between the limiting rib 1013 and the limiting block 1041 can prevent unnecessary rotation of the ring cover 104 and the housing assembly 101 when the sealing movable block 102 rotates. The position of the ring cover 104 and the housing assembly 101 is determined and will not rotate or shift due to external forces.

[0120] The number of transition channels 102a is unlimited; there can be one or more. For example, the number of transition channels 102a corresponds one-to-one with the number of additional storage cavities 101a. For example, please refer to... Figure 5 and Figure 8 There are two transition channels 102a.

[0121] The spacing angle between the two transition channels 102a is unlimited. The spacing angle between the two transition channels 102a is: the angle between the line connecting the center of the projection of the two transition channels 102a in a plane projection perpendicular to the top and bottom directions and the center of the projection of the central axis of the housing assembly 101. Please refer to [reference needed]. Figure 5 and Figure 9 The central axis of the housing assembly 101 is L. The line connecting the center of the projection of one of the transition channels 102a and the center of the projection of the central axis L of the housing assembly 101 is L1. The line connecting the center of the projection of the other transition channel 102a and the center of the projection of the central axis L of the housing assembly 101 is L2. The angle between L1 and L2 is the interval angle between the two transition channels 102a.

[0122] In some embodiments, please refer to Figure 5 The angle between the two transition channels 102a is 180°.

[0123] In other embodiments, please refer to Figure 9 The angle between the two transition channels 102a is 90°.

[0124] In some embodiments, please refer to Figure 7 , Figure 8 and Figure 10 The housing assembly 101 is a one-piece structure.

[0125] In other words, the housing assembly 101 is a one-piece manufactured structure. In this case, the number of additional storage cavities 101a formed within the housing assembly 101 can be one or more. The number of transition channels 102a and first positioning sub-slots 101b can also be one or more, and there is no limitation here.

[0126] In this embodiment, the one-piece housing assembly 101 is easy to manufacture, reduces assembly steps, and increases assembly efficiency.

[0127] In other embodiments, the housing assembly 101 includes a plurality of separately designed sub-oil tanks 101', each sub-oil tank 101' forming at least one additional storage cavity 101a.

[0128] In other words, multiple sub-oil tanks 101' are manufactured separately and spliced ​​together to form a shell assembly 101, and each sub-oil tank 101' can form one or more additional storage cavities 101a.

[0129] In this embodiment, the placement slot 101f of the shell assembly 101 formed by splicing multiple sub-oil tanks 101' can be a semi-enclosed structure or a fully enclosed structure, and there is no limitation here.

[0130] In this embodiment, the split housing assembly 101 allows the other sub-oil tanks 101' to continue operating even when one of them needs maintenance or replacement; only one sub-oil tank 101' needs to be replaced, resulting in high reliability.

[0131] The number of sub-oil tanks 101' can be two or more. For example, in some embodiments, please refer to... Figure 11 The housing assembly 101 is formed by splicing together two separately designed sub-oil tanks 101'. See other embodiments for details. Figure 12 The shell assembly 101 is formed by splicing together four separately designed sub-oil tanks 101'.
