When the atomizing seat is rotated to the second position, the first limiting part and the second limiting part cooperate to stop the rotation direction when switching from the first position to the second position.

[0015] This application provides an atomizer, including:

[0016] The atomizing component described in any of the above embodiments; and

[0048] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0049] This application provides an aerosol generating device. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 The aerosol generating device includes a power supply assembly 30 and an atomizer according to any embodiment of this application.

[0050] It should be noted that when the aerosol generating device adopts the atomizer of any embodiment of this application, the aerosol generating device has all the advantages of the atomizer of the corresponding embodiment, and the specific advantages are described in detail below.

[0051] It should be noted that the specific type of aerosol generating device in the embodiments of this application is not limited. For example, the aerosol generating device can be a medical nebulizer, an air humidifier, or a nebulizer such as an electronic cigarette.

[0052] The power supply component 30 is mainly used to supply power to the atomizer and control the opening and closing of the entire aerosol generation device. The atomizer is mainly used to contain the aerosol generation matrix and heat and atomize the aerosol generation matrix after being powered on. The aerosol generation matrix includes, but is not limited to, materials used for medical, health, and beauty purposes.

[0053] In some embodiments, the atomizer and power supply assembly 30 can be mechanically and electrically connected together axially. Furthermore, the atomizer and power supply assembly 30 can be detachably connected via magnetic, threaded, or snap-fit ​​connections. Both the atomizer and power supply assembly 30 can be replaced or upgraded individually, reducing replacement costs and saving user expenses.

[0054] Furthermore, the atomizer and / or power supply assembly 30 is not limited to being cylindrical; it can also be in other shapes such as elliptical or square cylindrical.

[0055] In some embodiments, the atomizer includes a liquid storage component 20 and an atomizing component 10. The liquid storage component 20 is used to contain the aerosol generating matrix, and the atomizing component 10 is electrically connected to a power supply component 30 to heat and atomize the aerosol generating matrix.

[0056] In related technologies, atomizing components can be transported and stored separately. That is, the atomizing component and the power supply component can be assembled at the user end to achieve electrical connection between the two. In order to facilitate the electrical connection between the atomizing component and the power supply component during assembly, the electrical connectors of the atomizing component are generally set to be exposed on the outer surface of the atomizing component, and may even be formed as protruding structures on the outside of the atomizing component. In atomizing components with this structure, the electrical connectors are easily subjected to external pressure during transportation or storage, which can lead to deformation or even damage, resulting in low reliability of the atomizing component.

[0057] In view of this, embodiments of this application provide an atomizing component; please refer to [link to relevant documentation]. Figures 3 to 6 The atomizing component 10 includes a first housing 11, an atomizing base 12, an atomizing core 13, and an electrical connector 14.

[0058] Furthermore, this application provides an atomizer; please refer to [link to relevant documentation]. Figure 1 and Figure 2 The atomizer includes a liquid storage component 20 and an atomizing component 10 according to any embodiment of this application.

[0059] It should be noted that when the atomizer adopts the atomizing component 10 of any embodiment of this application, the atomizer has all the advantages of the atomizing component 10 of the corresponding embodiment, and the specific advantages are described in detail below.

[0060] At least a portion of the atomizer base 12 is disposed within the mounting cavity 11a, and the first housing 11 facilitates the installation of the atomizer base 12 by providing the mounting cavity 11a. For details, please refer to... Figure 7 The mounting cavity 11a is open on one side, forming an opening 11m. The atomizing seat 12 can be inserted into the mounting cavity 11a from the side where the opening 11m is located, thus completing the assembly. This makes the assembly more convenient.

[0061] The atomizer core 13 is mounted on the atomizer base 12. That is, the atomizer base 12 provides a mounting base for the atomizer core 13.

[0062] The atomizing core 13 can convert electrical energy into other forms of energy and apply them to the aerosol-generating matrix, thereby atomizing the matrix and generating aerosols. For details, please refer to [link to details]. Figure 4 and Figure 5 The atomizing core 13 has an atomizing chamber 13a, in which the aerosol generating matrix is ​​heated and atomized to generate an aerosol.

[0063] The atomizing core 13 is electrically connected to the power supply assembly 30 via the electrical connector 14. The atomizing core 13 converts electrical energy into other forms of energy and applies them to the aerosol generating matrix, thereby heating and atomizing the aerosol generating matrix to generate aerosol.

[0064] The specific structure of the atomizing core 13 is not limited. Exemplarily, the atomizing core 13 includes a liquid guiding element and a heating element, with the liquid guiding element surrounding the outer periphery of the heating element. The heating element is electrically connected to the power supply assembly 30 via an electrical connector 14. The heating element converts electrical energy into other forms of energy and acts on the aerosol generating matrix, causing the aerosol generating matrix to be heated and atomized to generate aerosol. The liquid guiding element transports or delivers the aerosol generating matrix to the heating element, for example, through capillary action or other forces. The material of the liquid guiding element includes, but is not limited to, non-woven fabric, cotton, ceramic, glass, quartz, or fiber.

[0065] The specific method by which the heating element heats the aerosol to form a matrix is ​​not limited. Examples include resistance heating, electromagnetic induction heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, plasma heating, etc.

[0066] Specifically, the heating element that uses resistance heating is called a heating element. The heating element can convert electrical energy into heat energy, thereby heating the aerosol generation matrix to generate aerosols.

[0067] There are no restrictions on the specific type of heating element. For example, it can be a heating needle, heating film, heating mesh, heating plate, or heating wire, etc.

[0068] An electrical connector 14 is disposed on the atomizing base 12 and one end is electrically connected to the atomizing core 13. The atomizing base 12 and the first housing 11 are rotatably connected. The first housing 11 has a through hole 11d and a shielding part 11c. The atomizing base 12 has a first position and a second position. The atomizing base 12 rotates relative to the first housing 11 to switch from the first position to the second position.

[0069] It should be noted that the direction of relative rotation between the atomizing base 12 and the first housing 11 is not limited. For example, the atomizer is generally rod-shaped, and the direction of relative rotation between the atomizing base 12 and the first housing 11 can be the circumferential direction of the atomizer.

[0070] The specific manner in which the first housing 11 forms the through hole 11d and the blocking portion 11c is not limited. For example, please refer to... Figure 7 The mounting cavity 11a is open on both sides along the axial direction of the atomizer. One of the open sides is formed as an opening 11m, and the other open side is formed with a flange. The flange surrounds an opening. The blocking part 11c can be, for example, a strip plate. One end of the strip plate is connected to the flange, and the other end extends inward along the radial direction of the opening. In this way, the area of ​​the opening that is not blocked by the blocking part 11c constitutes the through hole 11d.

[0071] Please see Figure 3 In the first position, the shielding part 11c covers the other end of the electrical connector 14.

[0072] Please see Figure 6 In the second position, the other end of the electrical connector 14 is exposed through the through hole 11d.

[0073] It should be noted that the specific number of shielding parts 11c is not limited. Specifically, the number of electrical connectors 14 is generally two, one of which is electrically connected to the positive terminal of the power supply assembly 30, and the other is electrically connected to the negative terminal of the power supply assembly 30.

[0074] In some embodiments, two shielding portions 11c can also be provided, so that in the first position, one shielding portion 11c covers one electrical connector 14.

[0075] In other embodiments, there may be only one shielding part 11c, so that in the first position, one shielding part 11c can shield two electrical connectors 14.

[0076] In this embodiment of the atomizing assembly 10, during individual transportation or storage, the atomizing base 12 can be held in a first position. In this position, the shielding part 11c shields the electrical connector 14, which is located within the mounting cavity 11a and is thus protected by the shielding part 11c. This reduces the possibility of deformation or even damage to the electrical connector 14 due to external forces, thereby improving the reliability of the atomizing assembly 10. After the atomizing assembly 10 and the power supply assembly 30 are assembled, the atomizing base 12 is rotated relative to the first housing 11, switching the atomizing base 12 to a second position. In this position, the electrical connector 14 is exposed through the through hole 11d, allowing the other end of the electrical connector 14 to be electrically connected to the power supply assembly 30, thus facilitating the power supply path between the power supply assembly 30 and the atomizing core 13. In other words, the atomizing assembly 10 not only facilitates electrical connection with the power supply assembly 30 but also improves the reliability of the atomizing assembly 10 during transportation or storage.

[0077] The relative rotational fit between the atomizing base 12 and the first housing 11 is not restricted.

[0078] In some embodiments, please refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 One of the cavity wall of the mounting cavity 11a and the atomizing seat 12 has a first guide groove 12a, and the other has a first guide protrusion 11n. The first guide groove 12a extends in the direction of relative rotation between the atomizing seat 12 and the first housing 11, and the first guide protrusion 11n is movably disposed in the first guide groove 12a along the extending direction of the first guide groove 12a. In this way, the first guide protrusion 11n slides along the extending direction of the first guide groove 12a, and the atomizing seat 12 can be switched from a first position to a second position.

[0079] For example, please refer to Figure 7 and Figure 8 The cavity wall of the mounting cavity 11a may have a first guide protrusion 11n, and the atomizing seat 12 may have a first guide groove 12a.

[0080] The specific extension direction of the first guide groove 12a can be, for example, along the circumference of the atomizer. In this way, the atomizer seat 12 and the first housing 11 rotate relative to the circumference of the atomizer.

[0081] In this embodiment, the mating structure of the atomizing seat 12 and the first housing 11 rotating relative to each other is relatively simple, which is convenient for production and also convenient for user operation.

[0082] In some embodiments, please refer to Figure 8 The first guide groove 12a extends around one circle along the direction of relative rotation between the atomizing seat 12 and the first housing 11.

[0083] Specifically, the first guide groove 12a may extend circumferentially around the atomizer.

[0084] It should be noted that "extending one circumference" refers to the projection along a direction perpendicular to the direction of relative rotation between the atomizer seat 12 and the first housing 11 (e.g., the axis of the atomizer). The orthographic projection of the first guide groove 12a is circular, not arc-shaped.

[0085] Understandably, since the atomizer seat 12 is located within the mounting cavity 11a, the viewing angle is limited during the assembly process of the atomizer seat 12 and the first housing 11 when the first guide protrusion 11n and the first guide groove 12a are aligned and engaged. However, in this embodiment, the first guide groove 12a extends around the circumference of the atomizer, and the atomizer seat 12 is positioned in the mounting cavity 11a at any angle along the circumference of the atomizer through the opening 11m. During this process, the first guide protrusion 11n and the first guide groove 12a can be aligned and engaged. This simplifies the assembly difficulty of the atomizer seat 12 and the first housing 11, thereby improving the assembly efficiency of the atomizing assembly 10 and making it easier for users to assemble it themselves.

[0086] Of course, in other embodiments, the first guide groove 12a may extend less than one revolution along the direction of relative rotation between the atomizing seat 12 and the first housing 11. Specifically, taking the first guide groove 12a extending circumferentially along the atomizer as an example, the orthographic projection of the first guide groove 12a along the axial direction of the atomizer is arc-shaped. In this embodiment, the atomizing seat 12 cannot rotate to any angle relative to the first housing 11, which facilitates keeping the atomizing seat 12 in the first position or the second position.

[0087] In some embodiments, please refer to Figure 3 and Figure 6 The atomizing base 12 has a first limiting part 12b and the first housing 11 has a second limiting part. When the atomizing base 12 is rotated to the second position, the first limiting part 12b and the second limiting part cooperate to stop the rotation direction when switching from the first position to the second position.

[0088] For example, the first limiting part 12b may be a limiting protrusion, and the second limiting part may be formed by the side wall of the blocking part 11c.

[0089] by Figure 3 Taking the perspective shown as an example, Figure 3When the atomizing base 12 is in the first position, one side of the first limiting part 12b abuts against one side of the blocking part 11c in a clockwise direction. This prevents the first housing 11 from rotating counterclockwise relative to the atomizing base 12, thus keeping the atomizing base 12 in the first position. When the atomizing assembly 10 is electrically connected to the power supply assembly 30, the first housing 11 can be rotated counterclockwise, causing it to rotate counterclockwise relative to the atomizing base 12. Figure 6 When in the indicated position, the atomizer 12 switches to the second position, exposing the electrical connector 14, thereby achieving electrical connection with the power supply assembly 30.

[0090] Understandably, in Figure 3 and Figure 6 From the perspective shown, the first housing 11 is rotated counterclockwise until the other side of the blocking part 11c abuts against the other side of the first limiting part 12b. At this point, the first housing 11 can no longer be rotated counterclockwise. The user knows that it has been rotated into place, which makes it easier for the user to confirm the installation status of the atomizing component 10 and the power component 30.

[0091] In some embodiments, please refer to Figures 10 to 13 The liquid storage component 20 includes a second housing 21, which has a liquid storage chamber 21a for storing the aerosol generation matrix. The liquid storage component 20 is detachably connected to the atomizing component 10. The second housing 21 is rotatably connected to the atomizing seat 12 through the first housing 11.

[0092] It should be noted that the second housing 21 and the first housing 11 can be in a non-rotating fit, so that the second housing 21 and the first housing 11 rotate synchronously and are rotatably connected to the atomizing seat 12. Thus, when the second housing 21 is twisted, the first housing 11 rotates accordingly; or, when the first housing 11 is twisted, the second housing 21 rotates accordingly while the atomizing seat 12 and the sealing component 22 do not rotate. This simplifies operation and makes it easier for users to operate.

[0093] Here, the liquid storage chamber 21a may be selectively in liquid communication with the atomizing core 13.

[0094] In this way, once the aerosol generating matrix contained in the liquid storage component 20 is used up, only a new liquid storage component 20 needs to be replaced, and the atomizing component 10 does not need to be replaced. This helps to reduce the user's operating costs.

[0095] It is understandable that in this type of atomizer, the atomizer can use only the liquid storage component 20 to contain the aerosol generation matrix, that is, the atomizing component 10 itself may not store the aerosol generation matrix. In this way, when the atomizing component 10 is transported alone, there will be no leakage problem.

[0096] In some embodiments, please refer to Figure 5 and Figure 11 The liquid storage component 20 has an air outlet channel 20a. After the liquid storage component 20 and the atomizing component 10 are assembled, the air outlet channel 20a is connected to the atomizing chamber 13a. In this way, the aerosol generated in the atomizing chamber 13a flows out through the air outlet channel 20a for user use.

[0097] Here, the liquid storage chamber 21a can be arranged around the outer periphery of the gas outlet channel 20a, that is, the gas outlet channel 20a extends along the axial direction of the atomizer and is located approximately in the central area of ​​the atomizer, so that it is convenient for the user to hold and use the aerosol generating device.

[0098] In some embodiments, please refer to Figure 15 The atomizing component 10 also includes a first sealing plug 16. When the atomizing component 10 is not assembled with the liquid storage component 20 (e.g., when the atomizing component 10 is stored or transported separately), the opening 11m is sealed by the first sealing plug 16, which helps to ensure the cleanliness of the atomizing chamber 13a. When it is necessary to assemble the liquid storage component 20 with the atomizing component 10, the first sealing plug 16 is removed. In this way, the liquid storage component 20 can be assembled with the atomizing component 10 through the opening 11m, and the communication path between the atomizing chamber 13a and the air outlet channel 20a is opened.

[0099] The specific material of the first sealing plug 16 is not limited. For example, it can be a food-grade material such as silicone.

[0100] In some embodiments, please refer to Figure 15 The first sealing plug 16 has a suction air passage 16a. At least a portion of the first sealing plug 16 is placed in the mounting cavity 11a and connected to the atomizing assembly 10. One end of the suction air passage 16a is connected to the atomizing cavity 13a, and the other end is connected to the atmosphere.

[0101] Thus, the first sealing plug 16 can be used as a suction nozzle. The aerosol generating device may consist only of the atomizing component 10 and the power supply component 30. That is, even if the liquid storage component 20 is not assembled on the atomizing component 10, the aerosol generated in the atomizing chamber 13a can be drawn through the suction nozzle formed by the first sealing plug 16.

[0102] Of course, in this embodiment, after the first sealing plug 16 is removed, the liquid storage component 20 can still be assembled on the atomizing component 10. That is, the aerosol generating device can also include the liquid storage component 20, so as to use the nozzle on the liquid storage component 20 to draw aerosol.

[0103] In some embodiments, please refer to Figures 10 to 13The liquid storage assembly 20 also includes a sealing component 22 rotatably disposed on the second housing 21. The second housing 21 has a liquid storage chamber 21a and a liquid outlet 212a communicating with the liquid storage chamber 21a. The sealing component 22 has a liquid guiding hole 22a communicating with the atomizing core 13. The sealing component 22 and the atomizing seat 12 are anti-rotationally engaged. The sealing component 22 and the second housing 21 rotate relative to each other to open or close the communication path between the liquid guiding hole 22a and the liquid outlet 212a.

[0104] In this way, when the second housing 21 is twisted, the first housing 11 rotates accordingly; or, when the first housing 11 is twisted, the second housing 21 rotates accordingly while the atomizing seat 12 and the sealing component 22 do not rotate. This achieves simultaneous connection of the liquid outlet 212a and the liquid guide 22a, as well as the electrical connection of the electrical connector 14 and the power supply assembly 30, thereby reducing the user's operating steps and making it easier for the user to use.

[0105] The specific direction of relative rotation between the second housing 21 and the sealing component 22 is not limited. For example, it can be along the circumference of the atomizer.

[0106] Specifically, please refer to Figure 11 The second housing 21 includes a side shell 211 and a base 212. The side shell 211 forms a cavity, with one side of the cavity open. The base 212 is disposed on the open side of the cavity, thus forming a liquid storage chamber 21a with the side shell 211. A liquid outlet 212a is formed on the base 212. This facilitates the forming of the liquid storage chamber 21a and helps to reduce production difficulty.

[0107] Here, the specific material of the side enclosure 211 is not limited. For example, the side enclosure 211 can be made of a transparent or translucent material, allowing the user to observe the liquid level in the liquid storage tank 21a through the side enclosure 211, thus making it easier for the user to confirm whether the liquid storage component 20 needs to be replaced.

[0108] The specific structure of the sealing component 22 is not limited. Exemplarily, the sealing component 22 includes a support and a seal. The seal is disposed on the side of the support facing the liquid storage tank 21a. The seal is in sealing engagement with the second housing 21 (e.g., a side enclosure 211 and / or a base 212), thereby helping to reduce the risk of leakage of the liquid storage assembly 20. The support is used to support the seal, thereby helping to improve the structural strength of the sealing component 22.

[0109] The specific material of the seal is not limited here. For example, it can be a food-grade material such as silicone.

[0110] In this embodiment, the sealing component 22 can seal the liquid outlet 212a to cut off the communication path between the liquid guide hole 22a and the liquid outlet 212a, thereby facilitating the separate storage of the liquid storage component 20. After the liquid storage component 20 and the atomizing component 10 are assembled, the sealing component 22 and the second housing 21 are rotated relative to each other to open the communication path between the liquid guide hole 22a and the liquid outlet 212a. In this way, the aerosol generation matrix in the liquid storage chamber 21a can flow through the liquid outlet 212a and the liquid guide hole 22a in sequence, thereby achieving liquid supply to the atomizing component 10.

[0111] Furthermore, by controlling the relative rotation of the sealing component 22 and the second housing 21, the connection path between the liquid guide hole 22a and the liquid outlet hole 212a can be opened, and the connection path between the liquid guide hole 22a and the liquid outlet hole 212a can be cut off. In this way, the liquid storage component 20 can supply liquid or stop supplying liquid at any time.

[0112] In some embodiments, please refer to Figures 11 to 13 The liquid storage assembly 20 also includes a second sealing plug 23, which is detachably disposed in the air outlet channel 20a and seals the end of the air outlet channel 20a away from the atomizing chamber 13a. This helps to ensure the cleanliness of the air outlet channel 20a.

[0113] The specific material of the second sealing plug 23 is not limited. For example, it can be a food-grade material such as silicone.

[0114] In some embodiments, please refer to Figures 11 to 13 The liquid storage assembly 20 also includes an outer shell 24, which is fitted onto the second housing 21 (specifically, a side shell 211). The outer shell 24 has a sight hole 24a that penetrates both the inner and outer walls of the outer shell 24. By providing the outer shell 24, the second housing 21 (specifically, a side shell 211) can be protected, thereby improving the reliability of the liquid storage tank 21a. The sight hole 24a facilitates observation of the liquid level within the liquid storage tank 21a.

[0115] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 10 and Figure 11 The direction in which the atomizing seat 12 and the first housing 11 rotate relative to each other is the first direction, and the direction in which the sealing component 22 and the second housing 21 rotate relative to each other is the second direction. The plane containing the first direction and the plane containing the second direction are parallel.

[0116] Specifically, both the first and second directions can be the circumference of the atomizer.

[0117] This allows the forces acting on the relative rotation of the atomizing base 12 and the first housing 11, as well as the forces acting on the relative rotation of the sealing component 22 and the second housing 21, to be in the same direction, thus facilitating user operation.

[0118] Please see here. Figure 5 , Figure 8 , Figure 9 and Figure 14 In the first or second direction, the second housing 21 and the first housing 11 are anti-rotationally engaged, and the atomizing seat 12 and the sealing component 22 are anti-rotationally engaged.

[0119] The specific structure of the anti-rotation fit between the second shell 21 and the first shell 11 is not limited.

[0120] For example, please refer to Figure 7 and Figure 9 The first housing 11 has a first snap-fit ​​portion 11b, and the second housing 21 has a second snap-fit ​​portion 211a. The first snap-fit ​​portion 11b and the second snap-fit ​​portion 211a are snap-fitted together, thus the anti-rotation fit structure is relatively simple.

[0121] It should be noted that the specific structure of the first latching portion 11b and the second latching portion 211a is not limited. For example, please refer to [link to relevant documentation]. Figure 7 and Figure 9 One of them is a slot, and the other is a protrusion, which is engaged within the slot. Here, the slot can be a blind slot or a through slot, and this application does not impose any restrictions.

[0122] It should be noted that "through groove" refers to a groove where both sides of the groove are open along the direction where the convex and the groove meet; "blind groove" refers to a groove where the side of the groove facing the convex is open and the other side is closed along the direction where the convex and the groove meet.

[0123] The specific structure of the anti-rotation fit between the atomizing seat 12 and the sealing component 22 is not limited.

[0124] For example, please refer to Figure 3 , Figure 4 , Figure 10 and Figure 11 The atomizing seat 12 has a protrusion 121, which surrounds and forms at least a portion of the liquid channel 12c. The liquid channel 12c is in liquid communication with the atomizing core 13, and at least a portion of the protrusion 121 is inserted into the liquid guiding hole 22a.

[0125] In this way, the aerosol generation matrix in the liquid storage chamber 21a enters the liquid discharge channel 12c and is then guided to the atomizing core 13.

[0126] Specifically, the axes of the protrusion 121 and the liquid guiding hole 22a can overlap, but do not overlap with the axis of relative rotation of the atomizing seat 12 and the first housing 11. In this way, when the atomizing seat 12 and the first housing 11 rotate relative to each other, the protrusion 121 and the liquid guiding hole 22a cooperate to achieve the anti-rotation cooperation between the atomizing seat 12 and the sealing component 22.

[0127] In this embodiment, after the liquid storage component 20 and the atomizing component 10 are assembled, the anti-rotation fit between the atomizing seat 12 and the sealing component 22 can be realized simultaneously. This helps to reduce the user's operation steps and makes it easier for the user to use.

[0128] In some embodiments, please refer to Figures 11 to 14 One of the second housing 21 and the sealing member 22 has a second guide groove 211b and the other has a second guide protrusion 22b. The second guide groove 211b extends in the direction of relative rotation between the second housing 21 and the sealing member 22, and the second guide protrusion 22b is movably disposed in the second guide groove along the extension direction of the second guide groove 211b.

[0129] For example, when the sealing member 22 includes a sealing member and a support member, a second guide groove or a second guide protrusion 22b is formed on the support member. The structure of the support member is relatively high, which facilitates the formation of the second guide groove 211b or the second guide protrusion 22b.

[0130] For example, please refer to Figure 14 A second guide protrusion 22b is formed on the sealing component 22, and a second guide groove 211b is formed on the second housing 21.

[0131] The specific extension direction of the second guide groove 211b can be, for example, along the circumference of the atomizer. In this way, the sealing member 22 and the second housing 21 rotate relative to the circumference of the atomizer.

[0132] In this embodiment, the mating structure of the sealing component 22 and the second housing 21 rotating relative to each other is relatively simple, which is convenient for production and also convenient for user operation.

[0133] The specific number of the second guide groove 211b and the second guide protrusion 22b is not limited.

[0134] For example, there can be multiple second guide grooves 211b and second guide protrusions 22b, with each second guide groove 211b and second guide protrusion 22b corresponding to each other. Here, each second guide groove 211b extends less than one revolution along the direction of relative rotation between the sealing member 22 and the second housing 21, and the angle of rotation of the sealing member 22 relative to the second housing 21 is limited. This makes it easy for the user to know whether the connection path between the liquid outlet 212a and the liquid guide hole 22a is in a conductive state or a cut-off state.

[0135] For example, both the second guide groove 211b and the second guide protrusion 22b can be a single unit. Here, the second guide groove 211b can extend one full circle or less along the direction of relative rotation between the sealing member 22 and the housing 21. It is understood that if the second housing 21 is provided with the mounting groove 211c described below, the second guide groove 211b can be set to extend one full circle, for example, along the circumference of the atomizer. During the process of the sealing member 22 being positioned at any angle along the circumference of the atomizer in the mounting groove 211c, both the second guide protrusion 22b and the second guide groove 211b can achieve alignment and fit. This helps to simplify the assembly difficulty of the sealing member 22 and the housing 21, thereby improving the assembly efficiency of the liquid storage assembly 20 and facilitating self-assembly.

[0136] In some embodiments, please refer to Figure 13 and Figure 14 The second housing 21 has a mounting groove 211c, at least a portion of the sealing member 22 is rotatably disposed in the mounting groove 211c, and a second guide groove 211b is formed on the groove wall of the mounting groove 211c, the second guide groove 211b penetrating the inner wall and outer wall of the mounting groove 211c.

[0137] In other words, the second guide groove is a through groove.

[0138] Specifically, the mounting slot 211c and the liquid storage tank 21a are located on opposite sides of the base 212.

[0139] Here, if the second guide groove 211b extends less than one revolution along the direction of relative rotation of the sealing component 22 and the second housing 21, the situation inside the mounting groove 211c can be seen through the second guide groove 211b, which facilitates the alignment and cooperation of the second guide protrusion 22b and the second guide groove.

[0140] In some embodiments, please refer to Figure 4 and Figure 5 The atomizing component 10 also includes a liquid storage component 15, which surrounds the atomizing core 13. The liquid storage component 15 is made of a material with a certain adsorption capacity. The aerosol generating matrix that enters the atomizing component 10 through the liquid channel 12c wets the liquid storage component 15. The aerosol generating matrix adsorbed by the liquid storage component 15 is conducted to the atomizing core 13 through capillary force.

[0141] Specifically, the inner ring surface of the liquid storage component 15 is in direct contact with the atomizing core 13. In this way, the aerosol generation matrix adsorbed by the liquid storage component 15 is in direct contact with the atomizing core 13, thereby directly wetting the atomizing core 13. This is beneficial to further improve the wetting rate of the atomizing core 13, thereby shortening the user's waiting time for inhalation.

[0142] The specific material of the liquid reservoir 15 is not limited. For example, the liquid reservoir 15 may be made of an adsorbent material so as to adsorb a certain amount of aerosol to generate a matrix. Specifically, these adsorbent materials include one or more of polyethylene glycol terephthalate (PET) and nylon (polyamide, PA), etc.

[0143] The liquid storage device 15 can adsorb a certain amount of aerosol to generate a matrix, and the liquid storage device 15 has a certain liquid-locking performance. This helps to reduce the liquid supply speed to the atomizing core 13, thereby reducing the probability of leakage problems at the atomizing core 13.

[0144] The liquid guiding speed of the liquid guiding component can be faster than the liquid supply speed of the liquid storage component 15.

[0145] After the liquid storage component 20 and the atomizing component 10 are assembled, the aerosol generation matrix adsorbed by the liquid storage component 15 is conducted to the atomizing core 13 through capillary force. Specifically, the atomizing core 13 can be in direct contact with the liquid storage component 15, and the liquid guide component is provided with a guide hole, allowing the aerosol generation matrix adsorbed by the liquid storage component 15 to directly contact the liquid guide component through the guide hole. This allows for relatively rapid wetting of the liquid guide component, thereby guiding the liquid to the heating element. This helps reduce the user's waiting time for inhalation, improves the problem of dry burning of the heating element caused by slow liquid guiding speed, reduces the probability of burnt or scorched smells, and improves the user experience.
