When the user disassembles the nozzle to replace the atomizer, the condensation will be seen, which affects the user experience. In addition, the condensation is easily contaminated to other locations, which is not conducive to the handling of the condensation. Utility Model Content

DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0035] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0036] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and 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, and therefore cannot be understood as a limitation on this application.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0038] As mentioned in the background technology, in order to meet the user's suction needs, aerosol generating devices that can accommodate multiple atomizers have appeared on the market. The aerosol generating device includes a nozzle and an atomizer holder. The atomizer holder can accommodate multiple atomizers. The nozzle and the atomizer holder can rotate relative to each other to connect the nozzle to different atomizers, and then the aerosol generated by the atomizer can be discharged through the nozzle. However, aerosol condensation is easily generated at the nozzle. The condensation flows back through the nozzle to the end face of the atomizer facing the nozzle. When the user removes the nozzle to replace the atomizer, the condensation is visible, affecting the user experience. In addition, the condensation is easily contaminated to other parts, which is not conducive to the treatment of the condensation.

[0039] In order to solve the above problems, the embodiment of the present application provides a nozzle assembly 1 and an aerosol generating device. By dividing the nozzle assembly 1 into two parts, a nozzle 100 and a seal 200, the nozzle 100 can rotate relative to the atomizer 22, and the seal 200 is fixed relative to the atomizer 22, that is, the position where the atomizer 22 and the nozzle assembly 1 abut against each other does not rotate relative to each other, thereby reducing the condensation liquid from flowing back to the end surface of the atomizer 22 facing the nozzle assembly 1. When the nozzle assembly 1 is disassembled to replace the atomizer 22, a large amount of condensation liquid will not be seen, and the condensation liquid will not be contaminated everywhere, thereby improving the user experience.

[0040] See also Figure 1 and Figure 2 The present invention provides an aerosol generating device, comprising an atomizer assembly 2, a power supply assembly 3, and a mouthpiece assembly 1. The mouthpiece assembly 1 and the power supply assembly 3 are disposed at opposite ends of the atomizer assembly 2. The power supply assembly 3 is used to supply power to the atomizer assembly 2 to generate aerosol, and the mouthpiece assembly 1 is used to direct the aerosol for inhalation by the user.

[0041] Specifically, the atomizer assembly 2 includes a nebulizer holder 21 and a nebulizer 22. The nebulizer holder 21 can accommodate at least one nebulizer 22. When multiple nebulizers 22 are accommodated in the nebulizer holder 21, the nozzle assembly 1 and the atomizer assembly 2 can be rotated relative to each other so that the nozzle assembly 1 is connected to the nebulizer 22 in use in turn, thereby discharging the aerosol generated by the nebulizer 22 through the nozzle assembly 1.

[0042] See also Figure 2 and Figure 3 The nozzle assembly 1 provided in the embodiment of the present application is now described. The nozzle assembly 1 is mounted on an atomizer bracket 21 , which is used to accommodate a plurality of atomizers 22 .

[0043] The nozzle assembly 1 is detachably mounted on the atomizer bracket 21 ; the nozzle assembly 1 includes a nozzle 100 and a seal 200 , which is rotatably connected to the nozzle 100 . The seal 200 is configured to elastically abut between the nozzle 100 and each atomizer 22 , and the seal 200 and each atomizer 22 do not undergo relative displacement in the circumferential direction.

[0044] It should be noted that the nozzle assembly 1 is detachably mounted on the atomizer holder 21. The nozzle assembly 1 is assembled or disassembled as a whole. For example, before assembly, the nozzle assembly 1 is first assembled into a whole, and then the nozzle assembly 1 is assembled as a whole on the atomizer holder 21. For example, when replacing the atomizer 22, the nozzle assembly 1 is removed from the atomizer holder 21 as a whole. In addition, the nozzle 100 and the sealing member 200 can be connected to each other so that the nozzle 100 and the sealing member 200 can form a whole, and then the nozzle 100 and the sealing member 200 can be assembled or disassembled as a whole; alternatively, the nozzle 100 and the sealing member 200 can be connected as a whole by an additional fixing member 300, and then the nozzle assembly 1 can be assembled or disassembled as a whole by the fixing member 300.

[0045] The sealing member 200 is rotatably connected to the nozzle 100, meaning that the nozzle 100 and the sealing member 200 can rotate relative to each other under the action of an external force. Specifically, the nozzle 100 and the sealing member 200 can be rotatably connected directly, or through an intermediate member. Specifically, the nozzle 100 and the sealing member 200 can be rotatably connected by being interlocked, or through a central axis.

[0046] The seal 200 and the atomizer 22 do not undergo relative displacement in the circumferential direction, which means that the seal 200 and each atomizer 22 will not rotate relative to each other. The seal 200 and the atomizer 22 may or may not undergo relative displacement in the axial direction. When the seal 200 and the atomizer 22 can undergo relative displacement in the axial direction, the relative rotation of the seal 200 and the atomizer 22 can be limited by circumferential contact between the surfaces. When the seal 200 and the atomizer 22 cannot undergo relative displacement in the axial direction, the relative rotation of the seal 200 and the atomizer 22 can be limited by means of a snap connection or a fixed connection. In addition, the seal 200 and the atomizer 22 can be directly connected in a circumferentially limited manner, or a circumferentially limited connection between the seal 200 and the atomizer 22 can be formed by the atomizer bracket 21.

[0047] The nozzle assembly 1 in the embodiment of the present application includes a nozzle 100 and a seal 200. The nozzle 100 is rotatably connected to the seal 200, and the seal 200 is configured to prevent relative displacement with the atomizer 22 in the circumferential direction. This configuration ensures that when the nozzle 100 and the atomizer 22 are driven to rotate relative to each other so that the nozzle 100 is connected to different atomizers 22, the seal 200 and the atomizer 22 do not rotate relative to each other, and the seal 200 elastically abuts between the nozzle 100 and each atomizer 22, thereby reducing or preventing condensate in the nozzle 100 from flowing back to the end surface of the atomizer 22, thereby reducing the user from seeing condensate on the end surface of the atomizer 22 when disassembling the nozzle assembly 1, and reducing the situation where condensate is contaminated everywhere. At the same time, the configuration of the seal 200 also seals the nozzle 100 and the atomizer 22, reducing air leakage between the two, and can control the size of the suction resistance and ensure the suction taste. In addition, by setting the suction nozzle assembly 1 to be able to be installed and disassembled as a whole, the user will not separate the suction nozzle 100 and the seal 200 when disassembling the suction nozzle assembly 1, and the condensation liquid between the suction nozzle 100 and the seal 200 will not be exposed or stained everywhere, thereby improving the user experience.

[0048] In one embodiment, see Figure 3 The nozzle 100 has an air outlet channel 140, and the sealing member 200 has multiple connecting ports 210, each connecting port 210 is configured to be connected to the air flow channel 202 of each atomizer 22 in a one-to-one correspondence; the nozzle 100 and the sealing member 200 can rotate relative to each other so that the air outlet channel 140 is connected to each connecting port 210 in sequence.

[0049] Specifically, the number of connection ports 210 is the same as the number of atomizers 22. When the seal 200 is assembled and abutted between the mouthpiece 100 and each atomizer 22, since there is no relative rotation between the seal 200 and each atomizer 22, each connection port 210 on the seal 200 can be connected to the airflow channel 202 of each atomizer 22 in a one-to-one correspondence. Because the mouthpiece 100 and the seal 200 can rotate relative to each other, the air outlet channel 140 of the mouthpiece 100 can be sequentially connected to different connection ports 210 on the seal 200, thereby achieving communication between the air outlet channel 140 and the airflow channel 202 of different atomizers 22. In actual use, the mouthpiece 100 and the atomizer holder 21 can be rotated relative to each other so that the air outlet channel 140 of the mouthpiece 100 can be exactly connected to the airflow channel 202 of the atomizer 22 in use, thereby allowing the mouthpiece 100 to discharge the aerosol generated by the atomizer 22 in use.

[0050] In one embodiment, the atomizer 22 is connected to the atomizer bracket 21 in a circumferentially limited manner, and the seal 200 is connected to the atomizer bracket 21 in a circumferentially limited manner, so that the circumferentially limited connection between the seal 200 and the atomizer 22 can be achieved through the atomizer bracket 21, and at this time the nozzle 100 is rotationally connected to the atomizer bracket 21, and the nozzle 100 can be driven to rotate relative to the atomizer bracket 21 to achieve communication between the nozzle 100 and different atomizers 22.

[0051] A circumferentially limited connection refers to a structure that creates a circumferential limit, thereby restricting relative rotation between the two. Specifically, a limit block or a snap-fit ​​structure can be provided within the atomizer holder 21 to restrict rotation of the atomizer 22 relative to the atomizer holder 21. A limit block or snap-fit ​​structure can be used between the atomizer holder 21 and the seal 200 to restrict relative rotation; alternatively, a fixed member 300 can be used to create a circumferentially limited connection between the atomizer holder 21 and the seal 200.

[0052] In the present application, the nozzle 100 and the sealing member 200 can be directly connected to each other to form a whole and respectively connected to the atomizer bracket 21. Alternatively, the nozzle 100 and the sealing member 200 can be formed into a whole through an additional fixing member 300 and then connected to the atomizer bracket 21 through the fixing member 300. The above two situations are described in detail below.

[0053] In one embodiment, see Figure 3 The nozzle assembly 1 further includes a fixing member 300, to which the nozzle 100 and the sealing member 200 are both connected. The fixing member 300 is configured to be detachably connected to the atomizer bracket 21. The fixing member 300 allows the nozzle 100 and the sealing member 200 to be connected as a whole through the fixing member 300, and the nozzle assembly 1 can be assembled on the atomizer bracket 21 through the fixing member 300 and removed from the atomizer bracket 21 through the fixing member 300.

[0054] In one embodiment, the fixing member 300 is configured to be circumferentially limitedly connected to the atomizer bracket 21 , the mouthpiece 100 is rotatably connected to the fixing member 300 , and the sealing member 200 is circumferentially limitedly connected to the fixing member 300 .

[0055] Among them, the meanings of the rotation connection and the circumferential limit connection are as described above and will not be repeated here.

[0056] The fixing member 300 is connected to the atomizer bracket 21 in a circumferential limit manner, and the sealing member 200 is connected to the fixing member 300 in a circumferential limit manner, so that the sealing member 200 can rotate synchronously with the atomizer bracket 21, that is, there is no relative rotation between the sealing member 200 and the atomizer 22, thereby reducing the entry of condensate into the gap between the sealing member 200 and the atomizer 22.

[0057] The fixing member 300 is circumferentially limitedly connected to the atomizer bracket 21, and when the nozzle 100 is rotatably connected to the fixing member 300, the nozzle 100 is rotatably connected to the atomizer bracket 21, so that when the nozzle 100 and the atomizer bracket 21 rotate relative to each other, the nozzle 100 can be connected to different atomizers 22.

[0058] In this embodiment, the fixing member 300 is connected to the atomizer bracket 21 in a circumferentially limited manner, thereby ensuring the assembly reliability of the nozzle assembly 1 on the atomizer bracket 21. It is understandable that in other embodiments of the present application, the fixing member 300 and the atomizer bracket 21 can also be set to be rotatably connected, and then the fixing member 300 is connected to the nozzle 100 in a circumferentially limited manner, and the sealing member 200 is rotatably connected to the fixing member 300. This can also achieve a rotational connection between the nozzle 100 and the atomizer bracket 21 and a circumferentially limited connection between the sealing member 200 and the atomizer bracket 21. This is not intended to be the only limitation here.

[0059] In one embodiment, see Figure 3 The fixing member 300 is sleeved on the outside of the nozzle 100. That is, the inner circumference of the fixing member 300 and the outer circumference of the nozzle 100 are sleeved together to form a rotational connection between the fixing member 300 and the nozzle 100. This configuration allows the fixing member 300 and the nozzle 100 to be rotationally connected only by configuring the inner circumference of the fixing member 300 and the outer circumference of the nozzle 100 to be cylindrical surfaces. The outer circumference of the fixing member 300 can be configured as a cylindrical surface or other shapes, such as a quadrilateral, hexagon, octagon, or ellipse. This allows the aerosol generating device to have a variety of appearances to meet the different appearance requirements of users.

[0060] In one embodiment, see Figure 3 The nozzle 100 and the sealing member 200 are in contact with each other along the axial direction of the fixing member 300, and the fixing member 300 is sleeved on the outside of the nozzle 100 and the sealing member 200. In this way, the fixing member 300 not only connects the nozzle 100 and the sealing member 200 into one body, but also makes the entire nozzle assembly 1 more integrated and neat in appearance.

[0061] In one embodiment, see Figure 3The nozzle 100 includes a rotating part 110 and a suction part 120 that are integrally connected, and an air outlet channel 140 is provided through the rotating part 110 and the suction part 120. The sealing member 200 abuts against the side of the rotating part 110 that is away from the suction part 120. The fixing member 300 is sleeved on the outside of the rotating part 110 and the sealing member 200, and the rotating part 110 is rotatably connected to the fixing member 300. Among them, the rotating part 110 is used to realize the connection between the suction nozzle 100 and the fixing member 300 and the sealing member 200, and the suction part 120 is for the convenience of the user to suck. By sleeved on the outside of the rotating part 110, the fixing member 300 can be prevented from blocking the suction part 120.

[0062] In the present application, the fixing member 300 and the rotating part 110 form a rotational connection by being socketed with each other. Specifically, the inner peripheral surface of the fixing member 300 corresponding to the rotating part 110 is set to a cylindrical surface, and the outer peripheral surface of the rotating part 110 is set to a cylindrical surface, thereby realizing the rotational connection between the fixing member 300 and the rotating part 110.

[0063] In addition, in order to prevent the fixing member 300 and the rotating part 110 from being separated from each other in the axial direction during the assembly process or in the use process, please refer to Figures 3 to 5 A first convex ring 111 is convexly provided on the outer peripheral wall of the rotating part 110, and a first annular groove 310 is formed on the inner peripheral wall of the fixing member 300. The first convex ring 111 is snapped into the first annular groove 310 to limit the rotating part 110 and the fixing member 300 along the axial direction.

[0064] For details, please refer to Figures 3 to 5 The inner circumferential wall of the fixing member 300 is provided with a first rib 320 and a plurality of second ribs 330. The first rib 320 and the second ribs 330 are spaced apart along the axial direction of the fixing member 300. The first rib 320 extends axially along the fixing member 300, and the second ribs 330 are sequentially spaced apart along the circumference of the fixing member 300. The second ribs 330 extend circumferentially along the fixing member 300. The first rib 320 and the second ribs 330 together enclose a first annular groove 310. During assembly, the first protruding ring 111 of the rotating portion 110 is axially abutted against the second ribs 330, so that the first protruding ring 111 is engaged with the first annular groove 310. The provision of the plurality of second ribs 330 reduces the resistance of the second ribs 330 on the first protruding ring 111, allowing the first protruding ring 111 to be easily engaged with the first annular groove 310.

[0065] In the present application, a circumferential limiting structure can be provided between the fixing member 300 and the sealing member 200 to limit the fixing member 300 and the sealing member 200 along the circumferential direction, thereby enabling the fixing member 300 and the sealing member 200 to rotate synchronously. Specifically, the circumferential limiting can be achieved by circumferentially distributed protrusions and grooves. In addition, the circumferential limiting connection can also be achieved by mutually locking and fixing, for example, by welding, by clamping, or by screw locking.

[0066] The circumferential limiting connection between the fixing member 300 and the sealing member 200 is now described with an example.

[0067] In one embodiment, see Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The sealing member 200 is provided with a plurality of second grooves 220 spaced apart along the circumferential direction, and the fixing member 300 is provided with a plurality of second protrusions 340 spaced apart along the circumferential direction. Each second protrusion 340 is respectively engaged with a second groove 220, thereby forming a circumferential limit for the sealing member 200 and the fixing member 300, so that the sealing member 200 and the fixing member 300 can rotate synchronously. It is understood that in other embodiments of the present application, the second grooves 220 can also be formed on the fixing member 300, and the second protrusions 340 can also be formed on the sealing member 200, and this is not intended to be the sole limitation.

[0068] In one embodiment, see Figure 3 The second groove 220 is formed on the side of the seal 200 away from the suction nozzle 100, and the second protrusion 340 is inserted into the second groove 220. The seal 200 is supported on each second protrusion 340, and the side of the seal 200 facing the suction nozzle 100 is abutted against each second rib 330, that is, the seal 200 is axially abutted between each second protrusion 340 and each second rib 330, thereby preventing the seal 200 and the fixing member 300 from separating from each other in the axial direction, thereby ensuring the reliability of the connection between the seal 200 and the fixing member 300.

[0069] In one embodiment, see Figure 3 、 Figure 5 and Figure 6The rotating portion 110 of the nozzle 100 has a recessed receiving groove 112 on the side facing the seal 200, and a protrusion 240 on the side facing the nozzle 100. Each connection port 210 is located within the range of the protrusion 240, and the protrusion 240 is inserted into the receiving groove 112. The arrangement of the protrusion 240 and the receiving groove 112 can not only ensure the rotational stability of the seal 200 and the nozzle 100, but also block condensation deposited on the seal 200 to prevent the condensation from overflowing.

[0070] In one embodiment, see Figure 3 A liquid absorbing member 400 for absorbing condensed liquid is disposed between the sealing member 200 and the nozzle 100. The liquid absorbing member 400 can absorb as much condensed liquid as possible between the nozzle 100 and the sealing member 200, thereby preventing the condensed liquid from overflowing.

[0071] Optionally, the absorbent member 400 is absorbent cotton, which has good absorption capacity and a soft structure that does not affect the sealing effect between the sealing member 200 and the nozzle 100. It is understandable that in other embodiments, the absorbent member 400 can also be a sponge or other porous structure capable of absorbing liquid.

[0072] In one embodiment, see Figure 3 and Figure 6 The sealing member 200 has a plurality of first sealing ribs 250 protruding from the side facing the nozzle 100. Each first sealing rib 250 is respectively disposed around the end of each connection port 210 and is configured to abut against the end surface of the nozzle 100. Specifically, when a connection port 210 is connected to the air outlet channel 140 of the nozzle 100, the first sealing rib 250 corresponding to the connection port 210 abuts against the end surface of the corresponding air outlet channel 140 of the nozzle 100, thereby forming a sealed connection between the connection port 210 and the air outlet channel 140 and preventing condensation from entering between the nozzle 100 and the sealing member 200.

[0073] Specifically, each first sealing rib 250 is formed on the boss 240 , and each first sealing rib 250 abuts against an end surface of the rotating portion 110 of the suction nozzle 100 facing away from the suction portion 120 .

[0074] In one embodiment, see Figure 3 and Figure 7The nozzle 100 has an air outlet channel 140, and the sealing member 200 has a plurality of connecting ports 210, each of which is configured to connect each atomizer 22 with the air outlet channel 140. A plurality of second sealing ribs 260 are protruding from the side of the sealing member 200 facing away from the nozzle 100. Each sealing member 200 is disposed around the end of each connecting port 210, and each second sealing rib 260 is configured to elastically abut against the end surface of each atomizer 22. Specifically, when each second sealing rib 260 abuts against the end surface of each atomizer 22, each second sealing rib 260 surrounds the outer end of the airflow channel 202 of each atomizer 22, thereby forming a sealed connection between the connecting port 210 and the airflow channel 202, preventing condensate from flowing between the atomizer 22 and the sealing member 200.

[0075] In one embodiment, see Figure 3 and Figure 5 The nozzle 100 has a first connection portion 130 for circumferentially limiting connection with the power supply assembly 3. The first connection portion 130 is provided through the sealing member 200. In this embodiment, the nozzle 100 is connected to the power supply assembly 3 via the first connection portion 130. This allows the nozzle 100 and the power supply assembly 3 to rotate synchronously. For example, by rotating one of the power supply assembly 3, the nozzle 100, or the atomizer holder 21, the power supply assembly 3 and the atomizer holder 21 can be rotated relative to each other, so that the power supply assembly 3 supplies power to different atomizers 22. At the same time, the nozzle 100 and the atomizer holder 21 can also be rotated relative to each other, so that the nozzle 100 can communicate with different atomizers 22.

[0076] In one embodiment, see Figure 2 and Figure 3 A rotating shaft 4 is connected between the suction nozzle 100 and the power supply assembly 3. The bottom end of the rotating shaft 4 is connected to the power supply assembly 3, and the rotating top end is connected to the first connecting part 130 of the suction nozzle 100, thereby forming a connection between the suction nozzle 100 and the power supply assembly 3 through the rotating shaft 4.

[0077] For details, please refer to Figure 3 and Figure 5 A slot 131 is formed in the first connecting portion 130. The inner wall of the slot 131 includes a first flat surface 132. One end of the rotating shaft 4 includes a plug-in portion 41. The outer wall of the plug-in portion 41 includes a second flat surface 411. When the plug-in portion 41 is inserted into the slot 131, the first flat surface 132 and the second flat surface 411 abut against each other, thereby forming a circumferentially limited connection between the rotating shaft 4 and the suction nozzle 100. In addition, a third sealing rib 133 is protruding from the first flat surface 132. The third sealing rib 133 abuts against the second flat surface 411, thereby forming an interference fit between the plug-in portion 41 and the slot 131, thereby ensuring the reliability of the connection between the suction nozzle 100 and the rotating shaft 4.

[0078] In one embodiment, see Figure 3 The liquid absorbing member 400 is sleeved outside the first connecting portion 130 and radially abuts between the sealing member 200 and the first connecting portion 130 , thereby preventing condensed liquid from entering the atomizer bracket 21 through the gap between the sealing member 200 and the first connecting portion 130 .

[0079] For details, please refer to Figure 3 and Figure 6 The sealing member 200 has a through hole 230 formed in the center thereof, through which the first connecting portion 130 is disposed. A mounting groove 270 is formed inwardly on the side of the sealing member 200 facing the rotating portion 110. The mounting groove 270 communicates with the through hole 230, and the inner diameter of the mounting groove 270 is larger than that of the through hole 230. The liquid absorbent member 400 is received in the mounting groove 270 and is sleeved on the first connecting portion 130.

[0080] In one embodiment, see Figure 3 、 Figure 4 and Figure 8 The top end of the atomizer holder 21 is radially concave to form a flange 211 and a step 212. The seal 200 and the rotating portion 110 of the mouthpiece 100 abut against the flange 211 in sequence along the axial direction. The fixing member 300 is supported on the step 212. The fixing member 300 is sleeved on the outside of the rotating portion 110, the seal 200 and the flange 211. The outer peripheral surface of the fixing member 300 is flush with the outer peripheral surface of the atomizer holder 21, so that the appearance of the aerosol generating device is neat and beautiful. It can be understood that in other embodiments of the present application, the above-mentioned atomizer holder 21 can also be sleeved on the outside of the fixing member 300, which is not the only limitation here.

[0081] In the present application, a circumferential limiting structure can be provided between the fixing member 300 and the atomizer bracket 21 to limit the fixing member 300 and the atomizer bracket 21 along the circumferential direction, thereby enabling the fixing member 300 and the atomizer bracket 21 to rotate synchronously. Specifically, the circumferential limiting can be achieved by circumferentially distributed protrusions and grooves. In addition, the circumferential limiting connection can also be achieved by mutually locking and fixing, for example, by welding, by clamping, or by screw locking.

[0082] The circumferential limiting connection between the fixing member 300 and the atomizer bracket 21 in this embodiment is described in detail below.

[0083] In one embodiment, a first circumferential limiting structure and a first axial limiting structure are provided between the fixing member 300 and the atomizer bracket 21. The first circumferential limiting structure is used to limit the fixing member 300 and the atomizer bracket 21 in the circumferential direction so that the fixing member 300 and the atomizer bracket 21 can rotate synchronously; the first axial limiting structure is used to limit the fixing member 300 and the atomizer bracket 21 in the axial direction so that the fixing member 300 and the atomizer bracket 21 can slide synchronously in the axial direction. The provision of the first circumferential limiting structure and the first axial limiting structure can prevent the fixing member 300 and the atomizer bracket 21 from generating relative movement after assembly, thereby improving the connection stability between the fixing member 300 and the atomizer bracket 21 and improving the assembly stability of the nozzle assembly 1 on the atomizer bracket 21.

[0084] In one embodiment, see Figure 3 、 Figure 4 and Figure 8 The first axial retaining structure is a rotating snap-fit ​​structure comprising a first clamping block 350 and a rotating retaining slot 213. The first clamping block 350 is formed on the inner circumferential wall of the fixing member 300, while the rotating retaining slot 213 is formed on the outer circumferential wall of the flange 211. The rotating retaining slot 213 comprises a first groove portion 2131 and a second groove portion 2132 that communicate with each other. The first groove portion 2131 extends axially downward from the top side of the flange 211, while the second groove portion 2132 extends circumferentially from the bottom end of the first groove portion 2131 along the flange 211. During assembly, each first clamping block 350 is aligned with the opening of each first groove portion 2131, and the fixing member 300 is axially sleeved onto the exterior of the flange 211 until the fixing member 300 abuts against the step 212. The fixing member 300 and the atomizer bracket 21 are then rotated relative to each other, so that the first clamping block 350 is inserted from the first groove portion 2131 into the second groove portion 2132. The first clamping block 350 is axially limited by the axially opposing inner walls of the second groove portion 2132, thereby achieving axial limitation of the fixing member 300 and the atomizer bracket 21. In other embodiments of the present application, the first clamping block 350 may also be formed on the atomizer bracket 21, and the rotation clamping slot 213 may be formed on the fixing member 300. This is not intended to be the sole limitation herein.

[0085] In one embodiment, see Figure 4 and Figure 8The first circumferential limiting structure includes a plurality of first protrusions 214 formed on the atomizer bracket 21 and a first groove 360 ​​formed on the fixing member 300. The first protrusions 214 are spaced apart in sequence along the circumference of the fixing member 300. When the fixing member 300 and the atomizer bracket 21 rotate relative to each other so that the first block 350 is inserted into the second groove 2132, one of the first protrusions 214 is inserted into the first groove 360, thereby realizing the circumferential limiting of the fixing member 300 and the atomizer bracket 21, so that the fixing member 300 and the atomizer bracket 21 can be relatively fixed. During disassembly, it is only necessary to rotate the fixing member 300 or the atomizer bracket 21 in the opposite direction to overcome the clamping force between the first protrusion 214 and the first groove 360 ​​so that the first protrusion 214 is disengaged from the first groove 360, and then continue to rotate the fixing member 300 so that the first block 350 is rotated from the second groove portion 2132 to the first groove portion 2131, and finally separate the fixing member 300 from the atomizer bracket 21 in the axial direction so that the first block 350 is disengaged from the first groove portion 2131. It is understandable that in other embodiments of the present application, there may be multiple first grooves 360, each of which is clamped to each first protrusion 214 in a one-to-one correspondence. Alternatively, in other embodiments, the first groove 360 ​​may also be formed on the atomizer bracket 21, and the first protrusion 214 may be formed on the fixing member 300, which is not the only limitation here.

[0086] For details, please refer to Figure 8 The first protrusions 214 are protruding from the step 212 of the atomizer bracket 21, and each first protrusion 214 is disposed around the flange 211. The first groove 360 ​​is formed on the end surface of the fixing member 300 that abuts the step 212. It is understood that in other embodiments of the present application, the first protrusions 214 may also be formed on the outer peripheral wall of the flange 211, and the first grooves 360 may also be formed on the inner peripheral wall of the fixing member 300, and this is not intended to be a sole limitation.

[0087] In another embodiment of the present application, see Figure 9 The nozzle assembly 1 further includes a connector 500, which abuts between the nozzle 100 and the sealing member 200. The connector 500 is fixedly connected to the nozzle 100. The connector 500 has a second connecting portion 540 for circumferentially limiting connection with the power supply assembly 3. The second connecting portion 540 is provided through the sealing member 200. The provision of the connector 500 allows the connection between the nozzle 100 and the power supply assembly 3 to be formed through the connector 500, eliminating the need to directly connect the nozzle 100 to the power supply assembly 3. This simplifies the structure of the nozzle 100 and reduces the manufacturing cost of the nozzle 100.

[0088] In an embodiment with a connector 500, the connector 500 is formed with a docking port 510, which is arranged to be directly connected to the air outlet channel 140 of the suction nozzle 100. When the connector 500 and the suction nozzle 100 rotate synchronously, the docking port 510 is respectively connected to different connecting ports 210, thereby realizing the connection between the air outlet channel 140 and different atomizers 22.

[0089] In the embodiment with connector 500, see Figure 9 and Figure 10 A circular ring 520 is protruded from the connecting member 500 at a position corresponding to the docking port 510 . The suction nozzle 100 includes a suction tube 150 . The air outlet channel 140 is formed in the suction tube 150 . The suction tube 150 is inserted into the circular ring 520 , thereby forming a connection between the air outlet channel 140 and the docking port 510 .

[0090] In the embodiment with connector 500, see Figures 9 to 11 The rotating part 110 of the suction nozzle 100 is annular, and the connecting member 500 is received in the rotating part 110 of the suction nozzle 100. The outer peripheral wall of the connecting member 500 is provided with a plurality of third grooves 530 spaced in sequence along the circumferential direction, and the inner peripheral wall of the rotating part 110 is provided with a plurality of third protrusions 160 spaced in sequence along the circumferential direction. Each third protrusion 160 is respectively engaged in each third groove 530, thereby forming a circumferential limit connection between the suction nozzle 100 and the connecting member 500. In addition, the connecting member 500 is axially abutted between the top inner side surface of the suction nozzle 100 and the sealing member 200, thereby forming an axial limit of the connecting member 500 and the suction nozzle 100, so that the suction nozzle 100 and the connecting member 500 can move synchronously. It can be understood that in other embodiments of the present application, the suction nozzle 100 and the connecting member 500 can also be connected by interference fitting or snap connection.

[0091] In the embodiment with connector 500, see Figure 9 The seal 200 is provided with a recessed mating groove 280, which is used to form a plug-in fit with the atomizer 22 to reduce the condensation from entering the end surface of the atomizer 22. Specifically, the end surface of the atomizer 22 facing the seal 200 is provided with a rib 203, which is inserted into the mating groove 280.

[0092] In the embodiment with connector 500, see Figure 9 The fixing member 300 is inserted into the inner side of the top of the atomizer bracket 21, that is, all structures in the nozzle assembly 1 except the suction part 120 are inserted into the inside of the atomizer bracket 21, so that the outer surface of the aerosol generating device has high integrity and good aesthetics.

[0093] In the embodiment with connector 500, see Figure 12 and Figure 13The cross section of the outer peripheral wall of the fixing member 300 is polygonal, and the cross section of the inner peripheral wall of the atomizer bracket 21 is polygonal. When the fixing member 300 is axially inserted into the atomizer bracket 21, the outer peripheral wall of the fixing member 300 and the inner peripheral wall of the atomizer bracket 21 form a circumferential limit connection between the fixing member 300 and the atomizer bracket 21. In addition, please refer to Figure 12 and Figure 13 The outer wall of the fixing member 300 is further provided with a plurality of fourth protrusions 380 spaced apart in the circumferential direction, and the inner wall of the atomizer bracket 21 is provided with a plurality of fourth grooves 216, each of which is inserted into each of the fourth grooves 216, thereby strengthening the connection reliability between the atomizer bracket 21 and the fixing member 300.

[0094] Also, see Figure 12 and Figure 13 A second annular groove 370 is recessed on the outer peripheral wall of the fixing member 300, and a second convex ring 215 is convexly provided on the inner peripheral wall of the atomizer bracket 21. The second convex ring 215 is snapped into the second annular groove 370, thereby forming an axial limiting connection between the fixing member 300 and the atomizer bracket 21.

[0095] In another embodiment of the present application, the fixing member 300 may not be provided, and the nozzle 100 and the sealing member 200 may be directly connected. Specifically, the nozzle 100 and the sealing member 200 are rotationally connected, and the nozzle 100 and the sealing member 200 form an axially limited connection. The axially limited connection between the nozzle 100 and the sealing member 200 prevents the nozzle 100 and the sealing member 200 from separating in the axial direction, thereby allowing the nozzle 100 and the sealing member 200 to be assembled and disassembled as a whole.

[0096] Specifically, the top end of the seal 200 is inserted into the suction nozzle 100, the inner peripheral wall of the suction nozzle 100 is convexly provided with a fourth convex ring, and the outer peripheral wall of the seal 200 is convexly provided with a fourth annular groove. The fourth convex ring is clamped in the fourth annular groove, forming a rotational connection between the suction nozzle 100 and the seal 200, and forming an axial limiting connection between the suction nozzle 100 and the seal 200, so that the two are inseparable.

[0097] During assembly, the sealing member 200 can be fixedly connected to the atomizer bracket 21. Specifically, the connection can be achieved by the aforementioned connection method between the fixing member 300 and the atomizer bracket 21, which will not be repeated here.

[0098] In another embodiment of the present application, the atomizer 22 is rotatably connected to the atomizer bracket 21, the seal 200 is rotatably connected to the atomizer bracket 21, and the nozzle 100 is circumferentially limited to the atomizer bracket 21. In this embodiment, although the atomizer 22 is accommodated in the atomizer bracket 21, there is no rotation limiting structure between the atomizer 22 and the atomizer bracket 21. In this case, the atomizer 22 can be rotationally limited by the power supply assembly 3. At this time, the nozzle 100 or the atomizer bracket 21 can be rotated to connect the nozzle 100 to different atomizers 22, while also ensuring that the atomizer 22 and the seal 200 cannot rotate relative to each other.

[0099] Specifically, a concave-convex limiting structure or a snap-fitting structure may be provided between the power supply assembly 3 and the atomizer 22 to limit the rotation of the atomizer 22 relative to the power supply assembly 3 .

[0100] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
