[0029] In order to provide a clearer understanding of the technical features, objectives, and effects of the present application, the specific embodiments of the present application are now described in detail with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art may make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that the terms "longitudinal", "transverse", "up", "down", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings or the orientation or position relationship in which the product of this application is usually placed when in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this application, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0032] In this application, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0033] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above" a second feature may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. A first feature being "below" a second feature may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0034] Figures 1 to 7 An atomizing nozzle 1 in one embodiment of the present application is shown, which can be applied to an atomizer or an atomizing device to define a through airflow channel for a user to inhale the aerosol formed by the atomizer or the atomizing device.

[0035] The atomizer nozzle 1 may include a mouthpiece 10 and a base 20. The mouthpiece 10 defines an air outlet channel 111 for communicating with the airway within the atomizer or atomizing device and transmitting the aerosol atomized by the atomizer or atomizing device. The mouthpiece 10 is mounted on the base 20, which is configured to be detachably connected to the atomizer or atomizing device, allowing the atomizer nozzle 1 to be detachably mounted on the atomizer or atomizing device.

[0036] It should be understood that at least two liquid storage units 2 can be installed in the atomizer or atomizing device. The liquid storage unit 2 can be formed with a liquid storage cavity, in which an aerosol generating matrix is ​​stored. The atomizer or atomizing device can also be provided with at least two atomizing units 3, which are used to heat the aerosol generating matrix and atomize it to form an aerosol. Each atomizing unit 3 can correspond to a liquid storage cavity one by one. The atomizing unit 3 can also define an atomizing cavity 301. The aerosol generating matrix in the liquid storage cavity can be heated and atomized at the atomizing unit 3 to form an aerosol. The atomized aerosol can be discharged from the atomizing cavity 301 for use by the user. That is, the atomizer or atomizing device can accommodate at least two aerosol generating matrices of different flavors, which can be atomized to form aerosols of two flavors respectively.

[0037] The aerosol-generating substrate is usually in liquid form, and may include, but is not limited to, materials used for medical treatment, health preservation, wellness, beauty, and the like.

[0038] like Figure 3 and Figure 4 As shown, the base 20 also includes at least two atomization chambers 301 ( Figure 2 and Figure 3 The two spaces defined by the dotted lines can be schematically understood as the first connecting hole 211 that is detachably connected to at least part of the atomizing chamber 301. The nozzle 10 is rotatably connected to the base 20. The nozzle 10 can include a first position and a second position on the rotation path. Figure 3 As shown, when the nozzle 10 is in the first position, the air outlet channel 111 can be connected to one of the first connecting holes 211. Figure 4 As shown, when the suction nozzle 10 is in the second position, the air outlet channel 111 can be connected to another first connecting hole 211.

[0039] The present application arranges the suction nozzle 10 to be rotatably connected to the base 20, and sets a first position and a second position on the moving path of the suction nozzle 10, so that different air flow channels can be connected through the rotation of the suction nozzle 10, thereby achieving the inhalation of aerosols with different flavors.

[0040] It should be understood that there is an existing atomizer or atomizing device. When the user needs to change the flavor, the atomizer or atomizing device needs to be disassembled and the liquid storage unit 2 containing the aerosol generating matrix needs to be replaced (the liquid storage unit 2 forms the aforementioned liquid storage cavity).

[0041] There are also existing atomizers or atomizing devices that can accommodate multiple liquid storage units 2 and one atomizing unit 3. To change flavors, the user needs to operate and rotate different liquid storage units 2 so that they correspond to the atomizing units 3, so that the atomizing units 3 heat and atomize the aerosol-generating substrates in different liquid storage units 2. Alternatively, the user needs to operate and rotate the atomizing unit 3 so that it docks with different liquid storage units 2 to atomize aerosol-generating substrates of different flavors.

[0042] Such a replacement method has the problems of cumbersome operation and complicated replacement structure. If the position is frequently changed (rotated) during long-term use, the entire atomizer or atomizing device needs to be replaced or repaired, which increases the user's cost.

[0043] The present application allows the user to change the flavor by simply rotating the nozzle 10, which makes the user operation easier, the flavor conversion faster, and improves the user experience.

[0044] The present application sets the base 20 to be detachably connected to different atomizing chambers 301 respectively, so that the atomizing nozzle 1 can be detachably connected to the atomizer or atomizing device. This setting method enables the atomizing nozzle 1 to be set independently. During user use, if there is a problem with the parts in the atomizer or atomizing device, there is no need to replace the atomizing nozzle 1 synchronously. Similarly, during long-term use, if the atomizing nozzle 1 is damaged due to multiple rotations, there is no need to replace the atomizer or atomizing device synchronously, only the atomizing nozzle 1 needs to be replaced. Since the structure of the atomizing nozzle 1 is much smaller and simpler than the structure of the atomizer or atomizing device, if the rotating part is damaged and needs to be replaced, only replacing the atomizing nozzle 1 can greatly reduce the user's use cost compared to replacing the atomizer or atomizing device.

[0045] The independent placement of the atomizer nozzle 1 also facilitates cleaning of the atomizer nozzle 1 and the atomizer or atomizing device. After extended use, the user can disassemble the atomizer nozzle 1 and clean it separately. This expands the cleaning angle and field of view of the atomizer nozzle 1 (and the atomizer or atomizing device), further improving the user experience and extending the service life of the atomizer nozzle 1, the atomizer or the atomizing device.

[0046] It should be understood that when an atomizer or atomizing device can be equipped with at least two liquid storage units 2, the flavors of the aerosol-generating substrates within the installed liquid storage units 2 can be the same or different. When the atomizer or atomizing device can be equipped with three or more liquid storage units 2, the flavors of the aerosol-generating substrates contained therein can be all the same, all different, or some the same and some different. In other words, the flavors of the aerosol-generating substrates contained within the liquid storage units 2 installed in the atomizer or atomizing device can be freely selected and replaced by the user, and are not specifically limited here.

[0047] It should be understood that when the base 20 includes only two first connection holes 211, it can be connected to two atomizing chambers 301. In this embodiment, when the suction nozzle 10 is in the first position and the second position, the air outlet channel 111 can be connected to the two atomizing chambers 301 respectively. When the number of first connection holes 211 on the base 20 is three or more, it can be connected to three or more atomizing chambers 301. In this embodiment, the rotation path of the suction nozzle 10 can also include a third position, a fourth position, etc. Each position of the suction nozzle 10 can respectively enable the air outlet channel 111 to be connected to three or more atomizing chambers 301.

[0048] For example, when there are three first connection holes 211 on the base 20 and they can be connected to three atomizing chambers 301, the rotation path of the suction nozzle 10 may include a first position, a second position, and a third position. When the suction nozzle 10 is in the first position, the air outlet channel 111 is connected to one of the first connection holes 211 and the atomizing chamber 301. When the suction nozzle 10 is in the second position, the air outlet channel 111 is connected to another first connection hole 211 and the atomizing chamber 301. When the suction nozzle 10 is in the third position, the air outlet channel 111 is connected to the remaining first connection hole 211 and the atomizing chamber 301.

[0049] The number of the first connecting holes 211 can be flexibly adjusted according to the number of atomizing chambers 301 in the atomizer or atomizing device connected to the atomizing nozzle 1, and is not specifically limited here and will not be described one by one.

[0050] The present application will be further described below through an atomizing nozzle 1 having two first connecting holes 211 and capable of docking with an atomizer or atomizing device having two atomizing chambers 301 .

[0051] like Figures 2 to 5 As shown, the atomizing nozzle 1 has a vertical axis, and its horizontal cross section perpendicular to the axis is roughly rectangular, with rounded corners of optimized contours provided on the four corners.

[0052] In this embodiment, the nozzle 10 is disposed on the top of the base 20, and the two are coaxially arranged. The nozzle 10 can rotate relative to the base 20 with the axis of the atomizing nozzle 1 as the rotation axis.

[0053] The outer contour of the bottom end of the base 20 can be adapted to the outer contour of the top end of the atomizer or atomizing device to which it is connected, and in this embodiment is a flat rectangular structure. The contour of the bottom end of the nozzle 10 is adapted to the contour of the top end of the base 20 to ensure the smoothness of the overall outer contour of the atomizing nozzle 1.

[0054] The horizontal cross-sectional area of ​​the base 20 and nozzle 10 can gradually decrease from bottom to top along the axial direction. Furthermore, the width of the flat cross-sectional area varies more than the length. In other words, the flatness of the base 20 can be less than that of the nozzle 10, while the flatness of the top of the nozzle 10 can be greater than that of the bottom, for easier user experience.

[0055] It should be understood that "top" and "bottom" can be expressed in Figures 3 to 5 Alternatively, the end of the base 20 used for connecting to the atomizer or atomizing device can be regarded as the bottom end, and the opposite end can be regarded as the top end.

[0056] In other optional embodiments, the nozzle 10 can also be rotatably arranged on one side of the base 20. Or when the nozzle 10 is arranged on the top of the base 20, the axes of the two are arranged parallel and spaced apart, or the axes are arranged at a certain angle.

[0057] In other optional embodiments, the cross-section of the base 20 and / or the nozzle 10 along the axial direction may change gradually, or may first increase and then decrease, or may first decrease and then increase, or may remain unchanged. The change in the horizontal cross-section of the base 20 and / or the nozzle 10 along the axial direction may be a change in area or a change in shape. The horizontal cross-sections of the base 20 and / or the nozzle 10 may be the same or different in shape and the same or different in size.

[0058] In other optional embodiments, the horizontal cross-section of the base 20 and / or the nozzle 10 may also be circular, triangular, square, polygonal, irregular, or other shapes. Compared to a flat structure that gradually changes along an axis, the nozzle 10 may also be cylindrical, conical, or other structures.

[0059] like Figure 2 As shown, one of the nozzle 10 and the base 20 may include a rotating shaft 12, and the other may be provided with an assembly hole 221. The rotating shaft 12 is confined within the assembly hole 221 and is rotatably disposed within the assembly hole 221. The rotation of the rotating shaft 12 within the assembly hole 221 enables relative rotation between the nozzle 10 and the base 20.

[0060] This configuration allows the nozzle 10 and base 20 to rotate 360° clockwise or counterclockwise. During use, the user can rotate the nozzle 10 in a preferred direction and continue to cycle through the first and second positions. The user can also rotate the nozzle 10 back and forth in both directions within a 180° range to switch between the first and second positions. Multiple methods for switching between the first and second positions are available for users to choose from, accommodating their personal usage habits and improving their user experience.

[0061] In some other optional embodiments, a limiting structure can be further provided between the suction nozzle 10 and the base 20 to limit the rotation angle between the suction nozzle 10 and the base 20 so that the suction nozzle 10 can only rotate back and forth at a specific angle (covering a certain angle between the first position and the second position).

[0062] In some other optional embodiments, a slide rail structure can be provided between the suction nozzle 10 and the base 20, so that one of the two can be slid back and forth on the other (the sliding can be circumferential sliding to achieve relative rotation, or it can be sliding along an arc or a straight line) to achieve switching back and forth between the first position and the second position.

[0063] In this embodiment, the nozzle 10 includes a first body 11 and a rotating shaft 12 , wherein the rotating shaft 12 is disposed on the first body 11 . The base 20 includes a second body 21 and a first assembly portion 22 , wherein the assembly hole 221 is formed on the first assembly portion 22 .

[0064] like Figures 3 to 5 As shown, the bottom end of the first body 11 is connected to the top end of the second body 21. The first body 11 is generally hollow, with the bottom end of the cavity inside it being open and the top end being closed. An air outlet channel 111 is also formed inside the first body 11, separated from the cavity. The top end of the air outlet channel 111 passes through the top end of the first body 11. The rotating shaft 12 is coaxially arranged with the suction nozzle 10, located within the cavity of the first body 11, and the top end is disposed on the first body 11.

[0065] The two first connection holes 211 are now defined as a first connection hole 211 a and a first connection hole 211 b .

[0066] like Figure 3 As shown, when the nozzle 10 is in the first position, the air outlet channel 111 can be connected to the first connection hole 211a, and the cavity can be connected to the first connection hole 211b. Figure 4 As shown, when the nozzle 10 is in the second position, the air outlet channel 111 can be communicated with the first connection hole 211b, and the cavity can be communicated with the first connection hole 211a.

[0067] See also Figure 3 and Figure 4 The top profile of the air outlet channel 111 can roughly match the top profile of the first body 11. That is, when the top size of the first body 11 is larger than the size of the first connection hole 211, the horizontal cross-sectional dimensions of the air outlet channel 111 can gradually increase from the bottom to the top. Its vertical cross-section can be roughly triangular. This configuration improves the user experience and makes it easier to clean the air outlet channel 111.

[0068] In some other optional embodiments, the first body 11 may not have a cavity. When the nozzle 10 is in the first position, the air outlet channel 111 may communicate with the first connection hole 211a, and the first body 11 may block the first connection hole 211b. When the nozzle 10 is in the second position, the air outlet channel 111 may communicate with the first connection hole 211b, and the first body 11 may block the first connection hole 211a.

[0069] In some other optional embodiments, the rotating shaft 12 and the suction nozzle 10 may also be arranged on different axes. For example, when the suction nozzle 10 is arranged on one side of the top of the base 20, the rotating shaft 12 can be arranged coaxially with the base 20, and the axes of the suction nozzle 10 and the base 20 can be arranged parallel to each other and spaced apart.

[0070] In some other optional embodiments, the air outlet channel 111 may also be a channel with the same axial size. In this case, it may be a vertical (or inclined) channel with a straight axis, or a curved channel with a curved axis.

[0071] like Figure 6 and Figure 7 As shown, the second body 21 in this embodiment is hollow and cylindrical, with a closed top and an open bottom. The opening at the bottom is used for removable connection with an atomizer or atomizing device. Two first connection holes 211 are formed at intervals on the top wall of the second body 21. A first assembly portion 22 is also provided on the top wall of the second body 21.

[0072] The two first connection holes 211 can be symmetrically arranged on opposite sides of the first assembly portion 22. The three can be spaced apart and distributed in the length direction (of the horizontal cross section) of the flat atomizing nozzle 1 to facilitate spatial layout.

[0073] In this embodiment, the two first connection holes 211 are both circular holes.

[0074] In other optional embodiments, the shape of the first connecting hole 211 can also be set to other shapes such as rectangle, polygon, irregular, etc. The setting of its shape must ensure that it can be connected to the atomizing chamber 301 of the atomizer or atomizing device.

[0075] In other optional embodiments, when the number of the first connection holes 211 on the base 20 is three or more, they can be evenly spaced or unevenly spaced around the circumference of the first assembly portion 22. The multiple first connection holes 211 can also be concentrated on one side of the first assembly portion 22 to reduce the rotation angle between the nozzle 10 and the base 20.

[0076] In some embodiments, the first assembly portion 22 is cylindrical, with both ends of the hollow cylindrical structure penetrating therethrough, and the middle space can be regarded as an assembly hole 221. The rotating shaft 12 is rotatably disposed and confined in the cylindrical first assembly portion 22 (assembly hole 221).

[0077] The position limitation between the rotating shaft 12 and the first assembly portion 22 can be achieved by providing a mutually cooperating position limiting structure between the two.

[0078] For example, see also Figure 5 At least one limiting groove 121 may be formed on the rotating shaft 12, and at least one limiting protrusion 222 may be correspondingly provided on the inner wall surface of the first assembly portion 22. By setting the diameter of the assembly hole 221 to a compatible size with the diameter of the rotating shaft 12, and by securing the limiting protrusion 222 within the limiting groove 121, the rotating shaft 12 and the first assembly portion 22 can be axially limited, thereby achieving axial limitation between the suction nozzle 10 and the base 20.

[0079] The limiting groove 121 may also be formed on the inner wall of the first assembly portion 22 , and the limiting protrusion 222 is provided on the rotating shaft 12 .

[0080] In this embodiment, the rotating shaft 12 is a rectangular shaft, and the assembly hole 221 is a circular hole.

[0081] In other optional embodiments, when the rotating shaft 12 can also be set as a circular shaft, at this time, the assembly hole 221 can also be set as a square hole, a polygonal hole, etc. When the assembly hole 221 is a circular hole, the rotating shaft 12 can also be set as other polygonal shafts, etc., or can also be set as a circular shaft.

[0082] like Figure 5 As shown, in some embodiments, the bottom end of the first assembly portion 22 is located higher in the axial direction of the atomizer nozzle 1 than the bottom side of the top wall of the second body 21. The bottom end of the rotating shaft 12, which is located within the first assembly portion 22 and outside the assembly hole 221, is approximately at the same position in the axial direction of the atomizer nozzle 1 as the bottom side of the top wall of the second body 21.

[0083] This arrangement can prevent the first assembly portion 22 and the rotating shaft 12 from occupying the cavity defined by the base 20. That is, when the atomizing nozzle 1 and the atomizer or atomizing device are assembled with each other, this arrangement can make room for the atomizer or atomizing device assembled at the bottom end of the atomizing nozzle 1.

[0084] In some other optional embodiments, the first assembly portion 22 may also be configured as a hollow structure with a closed bottom end, and the rotating shaft 12 may be rotatably confined within the closed space at the bottom end.

[0085] In some embodiments, a locking structure may be provided between the nozzle 10 and the base 20 for locking and limiting the nozzle 10 when the nozzle 10 is in the first position and the second position.

[0086] By providing a snap-fit ​​structure, a certain limiting effect can be achieved in the first and second positions, ensuring the accuracy of each rotation to the first and second positions by the user. At the first and second positions, the air outlet channel 111 accurately mates with the two first connection holes 211, respectively, to avoid docking deviation. The snap-fit ​​structure can also serve as a reminder during the rotation of the nozzle 10. When the nozzle 10 is in the first or second position, after the snap-fit ​​structure is limited, the user needs to apply a greater force (relatively speaking) to continue rotating, which has a better reminder effect.

[0087] In some embodiments, the nozzle 10 may further include a second assembly portion 13 disposed on the first body 11. When the nozzle 10 moves back and forth between the first position and the second position, the first assembly portion 22 and the second assembly portion 13 may also move synchronously relative to each other. The engaging structure is disposed between the first assembly portion 22 and the second assembly portion 13, so that when the nozzle 10 is in the first position or the second position, the engaging structure can engage and limit the first assembly portion 22 and the second assembly portion 13, thereby achieving an engaging and limiting position between the nozzle 10 and the base 20.

[0088] like Figures 2 to 4 As shown, in this embodiment, the first assembly portion 22 and the second assembly portion 13 are both cylindrical. The second assembly portion 13 is movably mounted on the outside of the first assembly portion 22. The rotating shaft 12 is disposed within the second assembly portion 13 and movably extends through the first assembly portion 22. In other words, the first assembly portion 22 is radially located between the second assembly portion 13 and the rotating shaft 12.

[0089] The first assembly portion 22 , the second assembly portion 13 and the rotating shaft 12 are coaxially arranged, and their radial dimensions are adapted to each other to avoid movement in the horizontal direction.

[0090] Because the second assembly portion 13 and the rotating shaft 12 are both mounted on the first body 11, the first body 11, the second assembly portion 13, and the rotating shaft 12 rotate synchronously when the user rotates the nozzle 10. This coaxial arrangement allows the nozzle 10 to rotate back and forth between the first and second positions, achieving a positional limit between the first and second positions.

[0091] In some other optional embodiments, the assembly hole 221 may not be formed on the first assembly portion 22. The first assembly portion 22 and the second assembly portion 13 may also be configured as structures other than cylindrical. For example, when the suction nozzle 10 and the base 20 are configured to achieve relative rotation by providing an arc-shaped slide rail in the circumferential direction, the first assembly portion 22 and the second assembly portion 13 may also be a slide rail structure. In this embodiment, the first assembly portion 22 and the second assembly portion 13 may be respectively provided in the circumferential direction of the contacting ends of the suction nozzle 10 and the base 20.

[0092] It should be understood that the first body 11, the rotating shaft 12 and the second assembly portion 13 can be integrally formed, or fixed to each other by bolts, buckles, etc. The second body 21 and the first assembly portion 22 are similar.

[0093] like Figure 2 As shown, in this embodiment, the locking structure may include two first locking portions 223 and two second locking portions 131. The two first locking portions 223 are first defined as first locking portions 223a and first locking portions 223b, and the two second locking portions 131 are defined as second locking portions 131a and second locking portions 131b.

[0094] See also Figure 6 and Figure 7 The first engaging portions 223a and 223b are symmetrically disposed on opposite sides of the outer periphery of the side wall of the first assembly portion 22. The second engaging portions 131a and 131b are symmetrically disposed on opposite sides of the inner periphery of the side wall of the second assembly portion 13.

[0095] When the nozzle 10 is in the first position, the first engaging portion 223a corresponds to the second engaging portion 131a, and the first engaging portion 223b corresponds to the second engaging portion 131b. When the nozzle 10 is in the second position, the first engaging portion 223a corresponds to the second engaging portion 131b, and the first engaging portion 223b corresponds to the second engaging portion 131a.

[0096] In some other optional embodiments, when the base 20 is provided with three or more first connecting holes 211 and can be connected to an atomizer or atomization device having three or more liquid storage units 2, the number of the first snap-fitting portion 223 and the second snap-fitting portion 131 can also be set to three or more, which is not specifically limited here.

[0097] It should be understood that when the first assembly portion 22, the second assembly portion 13, and the rotating shaft are coaxially mounted one by one, and the number of the first engaging portions 223 and the second engaging portions 131 is three or more, the first engaging portions 223 and the second engaging portions 131 can be evenly spaced along the circumference of the first assembly portion 22 and the second assembly portion 13. The evenly spaced arrangement ensures that each first engaging portion 223 can be engaged with each second engaging portion 131 at each position.

[0098] like Figure 6 and Figure 7 As shown, one of the first engaging portion 223 and the second engaging portion 131 can be in the shape of a longitudinal rib, and the other can be in the shape of a longitudinal groove adapted thereto. Furthermore, the long axes of the first engaging portion 223 and the second engaging portion 131 can be parallel to the axis of the atomizing nozzle 1 .

[0099] In some other optional embodiments, the shapes of the first engaging portion 223 and the second engaging portion 131 may also be set to other shapes such as circle, polygon, arc, etc.

[0100] In other optional embodiments, the first engaging portion 223 and the second engaging portion 131 can also be configured as a magnetic structure. In this embodiment, the top end of the first assembly portion 22 and the bottom end of the second assembly portion 13 can also be configured to be in a mutually docked state (non-sheathed), and the first engaging portion 223 and the second engaging portion 131 are respectively disposed on the mutually docking end surfaces of the first and second assembly portions 22 and 13. Alternatively, the first and second assembly portions 22 and 13 can be removed, and the first and second engaging portions 223 and 131 can be directly disposed on the contacting end surfaces of the first and second bodies 11 and 21.

[0101] like Figure 6 As shown, in some embodiments, the top of the first assembly portion 22 may be recessed downward to form at least one movable groove 224. The movable groove 224 runs through both sides of the sidewall of the first assembly portion 22, so that the top portion of the first assembly portion 22 is divided into several parts along the circumferential direction.

[0102] It should be understood that since the engaging structure will be limited during rotation, if further rotation is required, the limit must be released. By providing the movable groove 224 at the top of the first assembly portion 22, compared to a cylindrical structure with a circular cross-section, the first assembly portion 22 can be more easily deformed under external force to release the limit.

[0103] In some other optional embodiments, the movable groove 224 may also be provided on the second assembly portion 13 and recessed upward along the bottom end of the second assembly portion 13 .

[0104] like Figures 3 to 5 As shown, in some embodiments, the atomizer nozzle 1 may further include a seal 30, which is disposed between the base 20 and the suction nozzle 10 to seal the gap between the base 20 and the suction nozzle 10 to prevent the infiltration of condensation, aerosol, etc.

[0105] Specifically, see Figure 6 The top wall of the second main body 21 of the base 20 can be recessed downward to form a mounting groove 212 , and the seal 30 is disposed in the mounting groove 212 , fixed relative to the base 20 , and movably relative to the nozzle 10 .

[0106] In some other optional embodiments, the sealing member 30 may also be fixed to the bottom end of the nozzle 10 and be movably disposed relative to the base 20 .

[0107] For example Figure 6 and Figure 7 As shown, the sealing member 30 may be formed with two second connection holes 31, and the portion defining the second connection holes 31 may be passed through the first connection hole 211. That is, the first connection hole 211 and at least a portion of the second connection hole 31 are overlapped, and a portion of the sealing member 30 is located within the first connection hole 211.

[0108] When the atomizer or atomizing device is assembled with the atomizing nozzle 1 , such an arrangement can ensure the tightness of the connection between the atomizing chamber 301 and the second connecting hole 31 (first connecting hole 211 ), thereby preventing aerosol from leaking out.

[0109] The sealing member 30 is further formed with a clearance hole 32 , which is located between the two second connection holes 31 in this embodiment and is used for the first assembly portion 22 to pass through.

[0110] It should be understood that the sealing member 30 can be made of a polymer material with certain elastic properties, and has an interference fit with the base 20 and the nozzle 10 to ensure that it has good sealing performance.

[0111] In some embodiments, at least a portion of the outer wall of the base 20 may be provided with an anti-slip structure to facilitate the user's disassembly and assembly of the atomizer nozzle 1 and the atomizer or atomizing device. The anti-slip structure may be an integrated protrusion, an anti-slip groove, or an anti-slip sheet, etc., which are not specifically limited here.

[0112] The present application also constructs an atomizer, which may include the atomizing nozzle 1 in any one of the above embodiments.

[0113] The base 20 of the atomizing nozzle 1 is detachably mounted on the atomizer. The atomizer may include at least two liquid storage units 2 and at least two atomizing units 3. The liquid storage units 2 are arranged in a one-to-one correspondence with the atomizing units 3. The liquid storage units 2 form a liquid storage cavity for storing an aerosol-generating substrate. The atomizing unit 3 defines an atomizing cavity 301. The aerosol-generating substrate in the liquid storage cavity can be heated and atomized in the atomizing unit 3 to form an aerosol. The atomized aerosol can be discharged from the atomizing cavity 301 for use by the user.

[0114] Taking the atomizer as an example, the atomizer chamber 301 is defined as atomizer chamber 301a and atomizer chamber 301b. When the atomizer nozzle 1 and the atomizer are assembled, the atomizer chamber 301a is connected to the first connecting hole 211a, and the atomizer chamber 301b is connected to the first connecting hole 211b.

[0115] When the user adjusts the mouthpiece 10 to the first position, the air outlet channel 111 communicates with the atomizing chamber 301a through the first connecting hole 211a. The user can use the aerosol flowing out of the atomizing chamber 301a. When the user adjusts the mouthpiece 10 to the second position, the air outlet channel 111 communicates with the atomizing chamber 301b through the first connecting hole 211b. The user can use the aerosol flowing out of the atomizing chamber 301b.

[0116] like Figure 8 As shown, the present application also constructs an atomization device, which may include the atomization nozzle 1 in any one of the above embodiments, or may include the atomizer in any one of the above embodiments.

[0117] The atomizing device may include a liquid storage unit 2, an atomizing unit 3 and a power supply unit 4. The functions of the liquid storage unit 2 and the atomizing unit 3 are the same as those described above and will not be described in detail herein.

[0118] The power supply unit 4 can be electrically connected to the atomization unit 3 to provide power to the atomization unit 3. The atomization unit 3 can perform heating and atomization operations under the power supply of the power supply unit 4.

[0119] It should be understood that in the atomizing device, the liquid storage unit 2, the atomizing unit 3, and the power supply unit 4 can be detachably provided. In this embodiment, if the atomizing device includes a unified housing, the atomizing nozzle 1 can be detachably connected to the housing to achieve detachable connection between the atomizing nozzle 1 and the atomizing chamber 301.

[0120] If a unified housing is not included, the atomizing nozzle 1 can be detachably connected to the liquid storage unit 2, the atomizing unit 3, or the power supply unit 4 to achieve detachable communication with the atomizing chamber 301. The specific unit to which the atomizing nozzle 1 is detachably connected needs to be flexibly set according to the specific structure and position relationship of the atomizing device and is not specifically limited here.

[0121] In some other optional embodiments, the liquid storage unit 2 and the atomizing unit 3 can also be connected to form an integral structure, and the power supply unit 4 is detachably connected to the liquid storage unit 2 and the atomizing unit 3. In this embodiment, the atomizing nozzle 1 can be detachably connected to the power supply unit 4, or detachably connected to the overall structure of the liquid storage unit 2 and the atomizing unit 3, so as to realize the detachable connection between the atomizing nozzle 1 and the atomizing chamber 301. The specific structure to which the atomizing nozzle 1 is detachably connected needs to be flexibly set according to the specific structure and positional relationship of the power supply unit 4, the liquid storage unit 2 and the atomizing unit 3, and is not specifically limited here.

[0122] In some other optional embodiments, the atomizing unit 3 and the power supply unit 4 can be connected to form an integral structure, and the liquid storage unit 2 is detachably connected to the atomizing unit 3 and the power supply unit 4. In this embodiment, the atomizing nozzle 1 can be detachably connected to the power supply unit 4, or detachably connected to the overall structure of the atomizing unit 3 and the power supply unit 4, so as to realize the detachable connection of the atomizing nozzle 1 to the atomizing chamber 301. The specific structure to which the atomizing nozzle 1 is detachably connected needs to be flexibly set according to the specific structure and positional relationship of the liquid storage unit 2, the atomizing unit 3 and the power supply unit 4, and is not specifically limited here.

[0123] It should be understood that the base 20 and the atomizer or atomizing device can be detachably connected by means of snaps, threads, bolts, interference fit, etc., which are not specifically limited here.

[0124] It can be understood that the above technical features can be used in any combination without limitation.

[0125] The above embodiments only express the specific implementation methods of the present application. The descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the present application. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present application, and several deformations and improvements can be made, which all fall within the scope of protection of the present application. Therefore, all equivalent transformations and modifications made to the scope of the claims of the present application should fall within the scope of coverage of the claims of the present application.
