Description

Title of the invention: Atomizer and aerosol-generating device. Technical field.

[0001] The present application falls within the field of atomization technology, in particular relating to an atomizer and an aerosol generating device.

[0002] TECHNICAL CONTEXT

[0003] The atomizer is part of the aerosol-generating device. It is therefore equipped with an atomizing component to atomize a liquid to be atomized and mix it with air to generate an aerosol that will be delivered to the user. In particular, a liquid guide element and a heating element are arranged inside the atomizing component. The liquid guide element is connected to a liquid storage compartment, and a liquid contained in the storage compartment can be drawn towards the liquid guide element by capillary action. The heating element is located within the liquid guide element and can therefore also come into contact with the liquid. The heating element produces heat to atomize the liquid that comes into contact with it, and then the atomized liquid is mixed with air to generate an aerosol.The liquid guide element acts as an intermediary between the liquid storage compartment and the heating element. The reason the heating element and the liquid storage compartment cannot be directly connected is to prevent the liquid from leaking directly from the heating element into the mist outlet. This would cause contact between the liquid and the electronic components in the aerosol generator, potentially damaging them. Therefore, in addition to its liquid guide function, the liquid guide element also partially restricts the flow of liquid, preventing it from penetrating the element's surface and flowing into the mist outlet.However, the requirements for the liquid storage capacity of the atomizer are becoming increasingly demanding, as a multifunctional aerosol will only function with a high liquid storage capacity. Consequently, the liquid in the storage compartment exerts increasing pressure on the liquid guide element, which is often punctured by the liquid, causing leaks. To prevent damage to the electronic components of the aerosol generator, an atomizer with improved sealing is necessary.

[0007] According to a second aspect, the embodiments of the present application also provide an aerosol-generating device, which includes the atomizer according to any one of the elements described above.

[0008] The atomizer provided in the embodiments of this application offers improved sealing by arranging the sealing element to seal the inner side of the liquid guide element. In particular, the liquid guide element guides the liquid contained in the liquid storage compartment to the heating element by capillary action. Consequently, the liquid guide element is normally filled with liquid. However, the volume of liquid is not uniformly distributed within the liquid guide element. The liquid tends to pool in the direction of gravity. The atomizer is generally in a vertical position, which causes the direction of the airflow in the mist outlet channel to approach the direction opposite to gravity.Therefore, the liquid in the liquid guide element generally collects at the end of the liquid guide element facing the base. Consequently, the sealing element fits at least partially against the inner wall of the element. liquid guide to seal the radial inner face of the liquid guide element, thus improving the atomizer's seal and preventing leaks.

[0026] DETAILED DESCRIPTION OF THE UTILITY CERTIFICATE

[0027] The technical solutions in the embodiments of this application shall be clearly and fully described in the following description with reference to the accompanying figures. Obviously, the embodiments described are only a part of the embodiments of this application, rather than exhaustively. Other embodiments based on the embodiments of this application and obtained by persons skilled in the art without creative work shall be included within the scope of protection of this application.

[0028] The embodiments of this application provide an atomizer and an aerosol-generating device to overcome the problem of the poor sealing effect of existing atomizers. This will be described below with reference to the accompanying figures.

[0029] The atomizer provided in the embodiments of this application can be used in an aerosol-generating device. The aerosol-generating device may include an atomizer and a central unit, and the central unit may include mechanisms such as a control mechanism and a power supply mechanism. Once the atomizer is connected to the central unit of the aerosol-generating device, the central unit's power supply mechanism provides electrical energy to the atomizer, so that the power supply mechanism can supply electrical energy to the atomizing component of the atomizer, enabling the atomizing component to produce heat. The specific mode of heat production of the atomizing component depends on the type of atomizing component.For example, when the atomizing component includes a structure such as a heating wire, it directly supplies an electric current to the atomizing component to heat the heating wire. When the atomizing component is a conductor, it provides a varying magnetic field to the atomizing component to excite it and generate a vortex current to produce heat. A control component in the central unit of the aerosol generator device may be equipped with a microphone. When the atomizer is connected to the central unit, the microphone can communicate with the mist outlet tube, allowing the microphone to detect the airflow in the mist outlet tube and thus control the power supply mechanism to provide the atomizing component with electrical power corresponding to the airflow in the mist outlet tube.

[0030] With reference to [Fig. 1], the atomizer provided in the embodiments of this application comprises a liquid cup 100, an atomizing component 200, and a base component 300. One end of the liquid cup 100 is provided with a cup mouth, and the opposite end is provided with a mist outlet 121. A liquid storage compartment 140 is provided inside the liquid cup 100. The atomizing component 200 comprises an atomizing tube 210, a liquid guide element, and a heating element 240.In which the heating element 240 is disposed in the liquid guide element, the atomizing pipe 210 is in communication with the mist outlet 121 and is sheathed on the outer peripheral side of the liquid guide element, the atomizing pipe 210 is provided with a liquid inlet 211 to communicate the liquid guide element with the liquid storage compartment 140. The base component 300 comprises a base 320 and . A sealing element 310. The base 320 is positioned to cover the cup opening. The sealing element 310 is mounted to the base 320 and extends along one side near the mist outlet 121 to be inserted at the end of the liquid guide element furthest from the mist outlet 121. The sealing element 310, the atomizing tube 210, and the mist outlet 121 are connected to form a mist outlet channel. The sealing element 310 fits at least partially against the inner wall of the liquid guide element to seal the radial inner face of the liquid guide element. The liquid guide element guides the liquid contained in the liquid storage compartment 140 to the heating element 240 by capillary action. Therefore, the liquid guide element is normally filled with liquid.However, the liquid volume is not uniformly distributed within the liquid guide element. The liquid tends to pool in the direction of gravity. The atomizer is typically in a vertical position, as shown in [Fig. 1], meaning the airflow direction in the mist outlet channel is close to the direction of gravity. Consequently, the liquid in the liquid guide element generally pools at the end of the liquid guide element towards the base 320. Therefore, the sealing element 310 fits at least partially against the inner wall of the liquid guide element to seal its radial inner surface, thus improving the seal and preventing leaks. Furthermore, the sealing element 310 can be fitted to the inner wall of the liquid guide element either butted together or with a gap.This is due to the high surface tension of the liquid, which considerably prevents the radial flow of the liquid towards the inside of the liquid guide element, even when they are spaced apart.

[0031] With reference to [Fig.1], in some embodiments, the sealing element 310 comprises a projecting structure 312 extending along the mist outlet orifice, the sealing element 310 further comprises a support portion 314 connected to the projecting structure, and the support portion is mounted on the base. The support portion 314 is butted against the inner wall of the liquid cup 100 so that the support portion, the liquid cup 100 and the atomizing pipe 210 enclose to form the liquid storage compartment 140. One end of the protruding structure 312 is arranged to pass through the support portion 314 and the other opposite end extends along a direction close to the mist outlet 121 to be inserted on the inner side of the end of the liquid guide element away from the mist outlet 121.In this way, the end face of the end of the sealing element 310 is oriented towards the base. The component 320 is located within the liquid storage compartment 140 and does not need to be sealed, preventing any liquid from leaking out. The support portion 314 also improves the sealing effect of the liquid storage compartment 140 and prevents direct liquid leakage from any gap between the base component 300 and the liquid cup 100.

[0032] Referring to [Fig.

[12] , in certain embodiments, the end of the atomizing pipe 210 near the support portion 314 is provided with a plurality of butt portions 212 projecting along the axial direction of the atomizing pipe 210, and the butt portions 212 are butted against the support portion 314. In this way, the support portion 314 can provide support to the end of the atomizing pipe 210 near the support portion 314 and thus improves the fixing effect of the atomizing component 200. The plurality of butt portions 212 are arranged at regular intervals to form a plurality of liquid inlet orifices 211, and the plurality of liquid inlet orifices 211 are distributed at regular intervals in the circumferential direction of the atomizing pipe 210.This allows the liquid to enter the liquid guide element from all directions, thereby increasing the liquid supply capacity of the aerosol-generating device. Referring to [Fig. 2], in some other embodiments, the end of the atomizing tube 210 near the support portion 314 is positioned at a gap from the support portion 314 to form a liquid inlet orifice 211. Such a structure is simple and simplifies the manufacturing of the atomizing tube 210. Furthermore, the length of the liquid inlet orifice 211 in the circumferential direction of the atomizing tube 210 is maximized (i.e., it is equal to the circumference of the atomizing tube 210), thus ensuring that the liquid enters the liquid guide element from all directions and improving the liquid supply capacity.

[0033] Referring to [Fig. 1], in certain embodiments, the sealing element 310 further comprises a first extension portion 315. The first extension portion 315 is disposed on the peripheral side of the support portion 314 and extends away from the liquid storage compartment 140. The outer peripheral side of the first extension portion 315 is butted against the inner wall of the liquid cup 100. In this way, when the liquid passes through a clearance between the support portion 314 and the inner wall of the liquid cup 100, it will be sealed by the first extension portion 315, thereby improving the sealing effect of the liquid storage compartment 140.

[0034] In certain embodiments, the projecting structure 312 passes through a reinforcing blade 316 and projects from the side of the reinforcing blade 316 that is away from the support portion 314. That is to say, as shown in Figures 2 and 6, the projecting structure 312 Projecting from the side of the reinforcing blade 316 away from the support portion 314, the end of the projecting structure 312, projecting from the reinforcing blade 316, can form a liquid collection ring 3121. During atomizer operation, condensate droplets flow in the direction near the base 320 along the inner side wall of the projecting structure 312 and ultimately collect at the liquid collection ring 3121, instead of continuing to flow outwards in the radial direction of the projecting structure 312 to the reinforcing blade 316. In this way, the condensate flow is controllable. In particular, when the volume of the condensate reaches a certain level, the droplets begin to drain.Since the condensate droplets are suspended from the liquid collection ring 3121, the droplet position is essentially at the point where the liquid collection ring 3121 is projected onto the base 320. A drainage channel or liquid absorption element 500, as described below, may be provided here, and the condensate may be drained from the atomizer or absorbed by the liquid absorption element 500 to prevent it from flowing onto other components and causing damage. For example, a common risk of condensate is that it may flow onto the microphone of the aerosol-generating device and damage it.

[0035] Referring to [Fig. 1], in certain embodiments, the base 320 comprises a cover body 321 and a second extension portion 322. The cover body 321 is arranged to cover the mouth of the liquid cup 100, and the second extension portion 322 is arranged on the peripheral side of the cover body 321 and extends in the direction of the support portion 314. The outer peripheral side of the second extension portion 322 is butted against the first extension portion 315, so that the first extension portion 315 can be better butted against the inner wall of the liquid cup 100, thus improving the sealing effect. The end face of the second extension portion 322, which is furthest from the cover body 321, can be butted against the reinforcing blade 316.In this way, support can be provided to the reinforcing blade 316 and the fastening effect of the reinforcing blade 316 can be improved.

[0036] Referring to [Fig. 4], in certain embodiments, an air exhaust groove 314a is disposed on the side of the support portion 314 opposite the liquid storage compartment 140, and the air exhaust groove 314a extends away from the protruding structure 312 along the radial direction of the protruding structure 312 from the junction between the protruding structure 312 and the support portion 314. The air exhaust groove 314a is in communication with the liquid storage compartment 140. In this way, the air exhaust groove 314a can supply air to the storage compartment of liquid 140 using a second space between the liquid guide element and the protruding structure 312, which avoids the fact that a negative pressure in the liquid storage compartment 140 caused by the loss of liquid prevents the liquid from being transported to the heating body 240 through the liquid guide element.

[0037] Referring to [Fig. 1], in certain embodiments, the liquid guide element comprises a first liquid guide element 220 and a second liquid guide element 230; the atomizing pipe 210 is sheathed on the outer peripheral side of the first liquid guide element 220; the first liquid guide element 220 is sheathed on the outer peripheral side of the second liquid guide element 230; the heating element 240 is disposed in the second liquid guide element 230; the radial outer peripheral side of the protruding structure 312 is butted against the radial inner peripheral side of the first liquid guide element 220; the end face of the protruding structure 312, separated from the support portion 314, is butted against the end face of the second liquid guide element 230.In this way, the radial inner side of the first liquid guide element 220 and the end face of the second liquid guide element 230 opposite the protruding structure 312 are sealed simultaneously, thus improving the sealing effect for the liquid.

[0038] The atomizer is part of the aerosol-generating device. It is therefore equipped with an atomizing component to atomize a liquid to be atomized and mix it with air to generate an aerosol that will be delivered to the user. Generally, the atomizing component of a traditional atomizer is mounted directly in the mist outlet tube, and then the mist outlet tube is mounted to the liquid cup by gluing or push-fitting. On the one hand, the internal space of the atomizing tube is narrow, making it difficult to mount the atomizing component in place; on the other hand, the atomizing tube must pass through the liquid cup and then fit into a mounting structure on the surface of the liquid cup, resulting in a long passage length and a high level of assembly difficulty.It can be seen that assembling traditional atomizers is difficult, resulting in low assembly efficiency and poor consistency. To make atomizer assembly more efficient and consistent, an easier-to-assemble atomizer is needed.

[0039] For the atomizer supplied in the embodiments of this application, by placing the mist outlet pipe on the liquid cup, by connecting one end of the atomizing component to the end of the mist outlet pipe furthest from the mist outlet orifice, and by connecting and adjusting the second end of the atomizing component to the protruding structure of the base component, Assembling the atomizer is easier. Specifically, when the mist outlet tube is integrated with the housing, the connection between the mist outlet tube and the housing is not necessarily considered during assembly, making assembly simpler. When the mist outlet tube is integrated with the housing, and the atomizing component is not located within the mist outlet tube but connected to the end of the tube furthest from the mist outlet, the atomizing tube does not extend independently to the base component but rather connects to the base component via the atomizing component. In this way, the length of the atomizing tube is reduced, and assembly is less difficult.Furthermore, an atomizing core is connected to the mist outlet pipe and the base component by insertion, thus avoiding operations such as rotating the atomizing core when assembling it to the mist outlet pipe (although rotation would be necessary for a threaded connection). It is sufficient to push the atomizing core towards the mist outlet pipe in the direction of insertion. Similarly, for assembling the base component, it is sufficient to push the base component towards the atomizing core in the direction of insertion, which simplifies the assembly process. In summary, the aerosol-generating device provided in the embodiments of this application can make the assembly of the aerosol-generating device easier.

[0040] Referring to [Fig. 1], the atomizer provided in the embodiments of this application comprises a liquid cup 100, an atomizing component 200 and a base component 300. In which the liquid cup 100 may comprise a housing 110 and a mist outlet tube 120, and one end of the mist outlet tube 120 is provided with a mist outlet orifice 121. The mist outlet tube 120 is connected to the housing by one end of the mist outlet orifice 121.The atomizing component may include a first end and a second end which are arranged opposite each other, and the first end of the atomizing component may be connected by fitting to the end of the mist outlet pipe 120 away from the mist outlet orifice 121; a base component, comprising a protruding structure 312 and a support portion which are connected to each other, the protruding structure 312 is connected by fitting to the second end of the atomizing component 200, and the end of the support portion away from the protruding structure is connected to the end of the housing away from the mist outlet orifice 121, in which the protruding structure 312 may be made of material such as silica gel and rubber.In certain specific embodiments, the protruding structure 312 is further provided with an airflow channel 3122, and the airflow channel 3122 is in communication with . the external environment. This allows the air path of the atomizing component to be communicated with the external environment.

[0041] In particular, with reference to [Fig. 13], in certain specific embodiments, a mounting cavity 130 is provided inside the housing 110, the housing 110 is further provided with a cup opening and a mounting port which are in communication with the mounting cavity 130, and the mist outlet pipe 120 is disposed in the mounting cavity 130; one end of the mist outlet pipe 120 is mounted to the mounting port and is provided with a mist outlet port 121, and the other end of the mist outlet pipe 120 extends in the direction where the cup opening is located. In fact, in the embodiment in which the mist outlet pipe 120 is not provided, the mounting port can directly act as the mist outlet port 121. As shown in [Fig.l], the edge of the mounting port and the edge of the mist outlet port 121 are connected to each other, so that the mist outlet pipe 120 can be formed integrally with the housing 110 or can be connected to the housing 110 by gluing or fitting once formed independently. One end of the atomizing component 200 is connected by insertion to the mist outlet pipe 120, as shown in [Fig. 1]. The atomizing pipe 210 of the atomizing component 200 is inserted into the mist outlet pipe 120, or the mist outlet pipe 120 is inserted into the atomizing pipe 210 of the atomizing component 200 or into the liquid guide element of the atomizing component 200. The end of the base component 300 near the mist outlet pipe 120 is connected by insertion to the end of the atomizing component 200 far from the mist outlet pipe 120; similarly, as shown in [Fig. 1].[l], the base component 300 is provided with a protruding structure 312, the protruding structure 312 is inserted into the liquid guide element or the atomizing pipe 210 of the atomizing component 200 is inserted into the base component 300. The base component 300 is arranged to cover the cup mouth, so as to seal the structure inside the mounting cavity 130.

[0042] Referring to [Fig. 1], it can be seen that, on the one hand, the atomizing component 200 is not necessarily mounted in the mist outlet pipe 120 (according to existing technology, the atomizing component 200 is mounted in the mist outlet pipe 120), but is only connected by insertion to the mist outlet pipe 120. Consequently, the atomizing component 200 is not necessarily mounted in a narrow space within the mist outlet pipe 120. When mounting the atomizing component 200 in the mist outlet pipe 120, it is difficult to mount the atomizing component 200 in a predefined position, which makes assembly difficult, assembly efficiency low, and consistency poor. weak. On the other hand, the length of the mist outlet pipe 120 has been shortened. Indeed, if the atomizing component 200 is mounted in the mist outlet pipe 120, the end of the mist outlet pipe 120 furthest from the mist outlet port 121 must extend to the base component 300. This makes assembly easier, even if the mist outlet pipe 120 and the housing 110 are positioned separately and need to be assembled. This is because, when the mounting gap of the mist outlet pipe 120 to the mounting port is constant, the longer the mist outlet pipe 120, the greater the mounting gap at the end furthest from the mist outlet port 121.Furthermore, since the atomizing component 200 is connected by insertion to the mist outlet pipe 120 and the base component 300, the atomizing component 200 and the base component 300 can be assembled first respectively, then the atomizing component 200 is inserted into the mist outlet pipe 120, then the base component 300 is inserted into the atomizing component 200 to complete the assembly, which makes the degree of modularity higher and the assembly more convenient (See below for a description of the atomizer assembly process).

[0043] Referring to [Fig. 1], in some embodiments, the atomizing component 200 comprises an atomizing pipe 210, a liquid guide element and a heating element 240. The heating element 240 is disposed on the inner side of the liquid guide element, the liquid guide element comprises a first liquid guide element 220 and a second liquid guide element 230, as shown in [Fig. 1].[3] The heating element 240 may be disposed on the inner peripheral side of the second liquid guide element 230, or in some other embodiments, the heating element 240 is enclosed within the second liquid guide element 230. Alternatively, if the second liquid guide element 230 is not provided, and only the first liquid guide element 220 is provided, the atomizing component 200 may be disposed on the inner peripheral side of the first liquid guide element 220 or enclosed within the first liquid guide element 220. The atomizing tube 210 is sheathed on the outer peripheral side of the liquid guide element. The atomizing tube 210 is inserted into the end of the mist outlet tube 120 located away from the mist outlet orifice 121 and is in communication with the mist outlet tube 120.The end of the base component 300 near the mist outlet pipe 120 is positioned by insertion at the end of the liquid guide element away from the mist outlet pipe 120 and fits into the inner peripheral side of the end of the liquid guide element away from the mist outlet pipe 120. This can improve the seal. of the atomizer, i.e., to prevent leakage of the liquid from the liquid storage compartment 140 through the atomizing component 200. In particular, the liquid guide element guides the liquid from the liquid storage compartment 140 by capillary action and disperses it over the entire atomizing component 200. Since the heating element 240 is disposed in the liquid guide element, it obviously comes into contact with the liquid in the liquid guide element; therefore, when the heating element 240 produces heat, the liquid is atomized and mixed with air to produce an aerosol, and is finally discharged from the mist outlet 121 to be supplied to the user.The distribution of the liquid in the liquid guide element is not perfectly uniform, because under the action of gravity, the liquid has a tendency to gather in the direction of the orientation of gravity. Therefore, when the atomizer is in the vertical position as shown in [Fig. 3], in the embodiment of [Fig. 3], the liquid has a tendency to gather in the direction in which the liquid guide element approaches the support portion 314. Consequently, the liquid that gathers at the position where the liquid guide element approaches the support portion 314 can easily escape the constraint of the liquid guide element and flow out of the liquid guide element.However, the end of the base component 300 near the mist outlet pipe 120 is inserted into the end of the liquid guide element away from the mist outlet pipe 120 and fits against the inner peripheral side of the end of the liquid guide element away from the mist outlet pipe 120. This prevents liquid from leaking from the liquid guide element near the support portion 314, thus improving the atomizer's seal. The structure of the base component 300, which is inserted into the mist outlet pipe 120, can be shown in [Fig. 4] as a protruding structure 312. This protruding structure 312 can be tubular in shape, and in other embodiments, it can also be in other irregular shapes.Furthermore, it should be noted that the atomizer and aerosol-generating device are often portable in actual use, and will therefore inevitably be positioned by the user in various ways. Consequently, in many cases, the atomizer is not in the vertical position shown in [Fig. 3], but may be placed horizontally or even upside down. However, when the user uses the atomizer, they generally place it in a vertical position similar to that shown in [Fig. 3], because when the user inhales the aerosol, they often lower their head to inhale, instead of raising it. And when the user inhales the aerosol, a large amount of liquid in the liquid guide element is consumed and transformed into atomized vapor, which is then mixed with air to produce a [missing word - likely "aerosol"]. the aerosol is finally expelled through the mist outlet 121. Consequently, the liquid guide element is continuously replenished with liquid from the liquid storage compartment 140, so that when the user operates it, the flow of liquid over the liquid guide element is most forceful, easily causing the liquid to overflow. Therefore, when the atomizer is held in the vertical position as shown in [Fig. 3] (i.e., in this position, the direction of mist discharge from the atomizer and the direction of gravity are approximately reversed), a sealing effect is provided at the end of the liquid guide element near the support portion 314, thus significantly improving the atomizer's sealing effect.The portion of the base component 300 inserted into the liquid guide element fits without play or at least partially with play to the inner peripheral side of the liquid guide element. This is due to the high surface tension of the liquid, which provides a sealing effect even with a play in the fit. The fit method can be selected according to the actual situation.

[0044] Referring to [Fig. 1], in some embodiments, the basic component 300 comprises a protruding structure 312 and a support portion 314, and one end of the protruding structure 312 extends in the direction near the mist outlet pipe 120 to be inserted at the end of the liquid guide element away from the mist outlet pipe 120. The protruding structure 312 can be made of a soft rubber material, such as silica gel or rubber, to improve the sealing effect; it can also be made of plastic or metal and other materials to improve the support for the atomizing component 200 while ensuring a certain sealing effect.The support portion 314 surrounds the end of the protruding structure 312 away from the mist outlet pipe 120, and the lateral side of the support portion 314 away from the protruding structure 312 is butted against the inner wall of the liquid cup 100 so that the liquid cup 100, the mist outlet pipe 120, and the atomizing pipe 210 are enclosed to form the liquid storage compartment 140. The support portion 314 can also be made of flexible rubber like the protruding structure 312, which improves the sealing effect of the liquid storage compartment 140. This prevents the liquid contained in the liquid storage compartment 140 from leaking out of the liquid storage compartment 140 through the gap between the support portion 314 and the inner wall of the liquid cup 100.The support portion 314 surrounds the end of the protruding structure 312 away from the mist outlet pipe 120, which can also be understood as the protruding structure 312 is arranged to pass to. through the support portion 314. The projecting structure 312 and the support portion 314 can be formed integrally, so that no clearance exists between the projecting structure 312 and the support portion 314, which prevents the liquid from leaking from the liquid storage compartment 140 through a clearance between the projecting structure 312 and the support portion 314. But in some embodiments, the projecting structure 312 and the support portion 314 are arranged separately from each other, which will be described in more detail later.

[0045] Referring to [Fig. 1], in certain embodiments, the liquid guiding element comprises a first liquid guiding element 220 and a second liquid guiding element 230. Both the first liquid guiding element 220 and the second liquid guiding element 230 are tubular in shape. The first liquid guiding element 220 may be made of a material such as a fibrous material or a porous body, in which the fibrous material may be: vegetable fiber, animal fiber, mineral fiber, or synthetic fiber.The first liquid guide element 220 can be made of materials such as cotton, non-woven fabric, fiberglass, porous ceramic, and porous metallic materials; the second liquid guide element 230 can be made of fibrous or porous materials, including plant fiber, animal fiber, mineral fiber, and synthetic fiber. The atomizing tube 210 is sheathed on the outer peripheral side of the first liquid guide element 220, the first liquid guide element 220 is sheathed on the outer peripheral side of the second liquid guide element 230, and the heating element 240 is disposed within the second liquid guide element 230.In this way, the liquid must pass through the first liquid guide element 220 to enter the second liquid guide element 230, and then come into contact with the heating element 240. This extends the liquid path, improves the blocking effect of the liquid guide element on the liquid, and reduces the risk of leakage of the liquid penetrating the surface of the liquid guide element (especially the second liquid guide element 230). The end of the base component 300 near the mist outlet pipe 120 is inserted into the end of the first liquid guide element 220 furthest from the mist outlet pipe 120, and the end face of the base component 300 near the mist outlet pipe 120 is at least partially butted against the end face of the second liquid guide element 230.In this way, when the user uses the atomizer, the lower end of the second liquid guide element 230 is sealed in the direction. of gravity, which prevents the liquid from penetrating the surface of the second liquid guide element 230 and leaking here, improves the liquid sealing effect, moreover, which strengthens the second liquid guide element, prevents detachment and deformation of the second liquid guide element and prolongs the service life of the second liquid guide element.

[0046] With reference to [Fig.1], in certain embodiments, the basic component 300 further includes a first extension portion 315. One end of the first extension portion 315 is connected to the side of the support portion 314 near the housing 110, and the other opposite end extends in the direction away from the mist outlet pipe 120, which is equivalent to providing a skirt for the support portion 314.The outer peripheral side of the first extension portion 315 is butted against the inner wall of the housing 110, which is equivalent to widening the contact area between the support portion 314 and the inner wall of the liquid cup 100, so that when the liquid enters the adjustment gap between the support portion 314 and the liquid cup 100, once the support portion 314 is pierced, the first extension portion 315 also provides a sealing effect, thus preventing the liquid from leaking and improving the sealing effect.

[0047] Referring to [Fig. 2], in some embodiments, the basic component 300 further comprises a reinforcing blade 316. The reinforcing blade 316 is arranged to bear against the side of the support portion 314 away from the liquid storage compartment 140 to support the support portion 314. The hardness of the reinforcing blade 316 may be greater than the hardness of the support portion 314; for example, the reinforcing blade 316 may be made of laminated steel or hard plastic, and the support portion 314 may be made of soft rubber. The support portion 314 can provide a good sealing effect, and the reinforcing blade 316 helps to prevent deformation of the support portion 314. Deformation of the support portion 314 will cause it to not be butted against the inner wall of the liquid cup 100 and will therefore cause liquid leakage; consequently, the reinforcing blade 316 improves the sealing effect.

[0048] With reference to Figures 2, 6, and 8, in certain embodiments, for example, the embodiment of [Fig. 2], the reinforcing blade 316 surrounds the end of the projecting structure 312 away from the mist outlet pipe 120. The projecting structure 312 projects from the side of the reinforcing blade 316 away from the support portion 314, as shown in Figures 2 and 6. The projecting structure 312 projects from the side of the reinforcing blade 316 away from the support portion 314, and the end of the projecting structure 312 projecting from the reinforcing blade 316 can form a liquid collection ring 3121. With reference to [Fig. 2], the lower part of the liquid collection ring 3121 is lower than the lower part of the blade. reinforcement 316, in other words, the side of the liquid collection ring 3121 away from the second liquid guide element 230 protrudes relative to the side of the reinforcement blade 316 away from the second liquid guide element 230, and the liquid collection ring 3121 can prevent the condensate liquid from flowing to the position where the reinforcement blade 316 is located, thus improving the sealing effect and effectively preventing leakage. During the operation of the atomizer, condensate droplets flow in the direction near the base 320 along the inner side wall of the protruding structure 312 and finally meet at the liquid collection ring 3121, instead of flowing outwards again in the radial direction of the protruding structure 312 to the reinforcing blade 316. In this way, the condensate is controllable.In particular, when the volume of the condensate reaches a certain level, the droplets begin to drip. Since the condensate droplets are suspended from the liquid collection ring 3121, the droplet position is essentially at the point where the liquid collection ring 3121 is projected onto the base 320. A drainage channel or liquid absorption element 500, as described below, can be provided here, and the condensate can be drained from the atomizer or absorbed by the liquid absorption element 500 to prevent it from flowing onto other components and causing damage. For example, a common risk of condensate is that it may flow onto the microphone of the aerosol-generating device and damage it.

[0049] Referring to [Fig. 8], in some embodiments, the reinforcing blade 316 surrounds the end of the protruding structure 312 away from the mist outlet pipe 120, and the protruding structure 312 and the reinforcing blade 316 are formed as one. Further referring to [Fig. 9], the protruding structure 312 and the reinforcing blade 316 are formed as one here, thus creating a stronger support structure; that is, it secures, on the one hand, the end of the atomizing component 200 near the base 320, and on the other hand, the support portion 314. In this case, the protruding structure 312 and the reinforcing blade 316 can be made of a hard material such as plastic or metal (including alloys) to provide a good support effect.

[0050] Referring to [Fig. 8], in certain embodiments, an air exhaust groove 314a is disposed on the side of the support portion 314 opposite the liquid storage compartment 140, and the air exhaust groove 314a extends in the radial direction of the protruding structure 312 from the junction between the protruding structure 312 and the support portion 314 towards the direction away from the protruding structure 312 to the liquid storage compartment 140. This is equivalent to communicating the clearance between the protruding structure 312 and the liquid guide element with the liquid storage compartment 140, thus forming an air passage. When the amount of liquid in the liquid storage compartment 140 decreases, the liquid storage compartment 140 is replenished with air via the air passage to equalize the air pressure and prevent excessive negative pressure in the liquid storage compartment 140, which would prevent the liquid from flowing to the heating element 240. See below for a description of the first space 312c.

[0051] Referring to [Fig. 2], in some embodiments, the end of the atomizing tube 210 facing the base component 300 is at least partially separated from the support portion 314 to form a liquid inlet orifice 211 that connects the liquid guide element with the liquid storage compartment 140. Since the support portion 314 is located at the bottom of the liquid storage compartment 140, the liquid inlet orifice 211 is positioned there to fully utilize the liquid and avoid waste caused by residual liquid in the liquid storage compartment 140. In some other embodiments, for example, the embodiment of [Fig. 1], the heating element 240 is separated from the liquid inlet orifice 211 in the axial direction of the atomizing tube 210, and when the user operates the atomizer, the element heating element 240 is higher than the liquid inlet orifice 211.This means that in order for the liquid to reach the heating element 240, it must first overcome gravity and rise in the liquid guide element to the heating element 240. This partially reduces the pressure exerted by the liquid in the liquid storage compartment 140 on the liquid in the liquid guide element and prevents leakage of the liquid through the surface of the liquid guide element under excessive pressure. In the embodiment of [Fig. 1], the projecting structure 312 is also used to seal the inner peripheral side of the liquid guide element, thus further improving the sealing effect.

[0052] Referring to [Fig. 1], in certain embodiments, along the axial direction of the atomizing pipe 210, the height of the liquid inlet orifice 211 from the support portion 314 is a. The penetration depth of the protruding structure 312 into the liquid guide element is b. A and B satisfy a constraint l.5a < b < 10a. When b <l,5a, la structure saillante 312 ne fournit qu’un mauvais effet de support au composant d’atomisation 200, et le composant d’atomisation 200 se secoue, ce qui entraîne la fuite du liquide. Et lorsque b> 10a, the heating element 240 is raised (this is because the heating element 240 cannot be shaded by the protruding structure 312, but must be exposed to the atomization channel formed by connecting the protruding structure 312, the atomization component 200 and (the mist outlet pipe 120), therefore, the liquid is difficult to reach the heating element 240, which causes the heating element 240 to burn out and damage the heating element 240. And when b is within the above range, it is possible to overcome the above problems.

[0053] With reference to Figures 1 and 11, in certain embodiments, the atomizer further comprises a first electrode 410 and a second electrode 420. The base component 300 comprises a base 320 and a sealing element 310, and the base 320 can be inserted into the mounting cavity 130 through the cup opening, thus allowing the base component 300 to be connected by insertion to the liquid cup 100. The sealing element 310 comprises the protruding structure 312 and the support portion 314, and the sealing element 310 is disposed on the side of the base 320 opposite the atomizing component 200. The first electrode 410 and the second electrode 420 are spaced apart and are both arranged to pass through the base 320.The protruding structure 312 is provided with a wire passage channel that runs through the protruding structure 312 along its axial direction. The wire passage channel may comprise a first wire passage channel 312a and a second wire passage channel 312b. The first electrode 410 can be electrically connected to the heating element 240 by passing through the first wire passage channel 312a. The second electrode 420 can be electrically connected to the heating element 240 by passing through the second wire passage channel 312b. One of the first electrode 410 and the second electrode 420 can be connected to the positive terminal of the heating element 240, and the other can be connected to the negative terminal of the heating element 240.The first electrode 410 and the second electrode 420 are structures that electrically connect the atomizer to the central unit of the aerosol generator. Typically, two contacts (or pins) extend from the central unit; when the atomizer is partially connected to the central unit, these two contacts make contact with the first electrode 410 and the second electrode 420, respectively, to establish an electrical connection. In a traditional aerosol generator, the wires leading from the positive and negative terminals of the heating element 240 are suspended in the mist outlet channel and come into contact, causing a short circuit.In the embodiments provided in this application, the lead wires of the two poles of the heating element 240 are arranged respectively in the first lead wire channel 312a and the second lead wire channel 312b, so as to ensure that they are spaced apart without short-circuiting. Furthermore, with reference to Figures 1 and 11, the first electrode 410 may be an electrode nail and the second electrode 420 may be an electrode ring; the electrode nail. The electrode ring and the electrode are separated from each other by an insulating silica gel 430 to form two independent poles. Of course, the first electrode 410 and the second electrode 420 can also be in the form of a conventional electrode, provided that the first electrode 410 and the second electrode 420 are spaced apart.

[0054] Referring to [Fig. 6], in some embodiments, the sealing element 310 is provided with an adhesive injection groove 311 on the offset side of the atomizing component 200. The first and second feed wire channels 312a and 312b pass through the bottom of the adhesive injection groove 311. Obviously, one end of each of the first and second feed wire channels 312a and 312b is in communication with the liquid guide element, since the heating element 240 is disposed in the liquid guide element. Consequently, the liquid can leak along either the first or second feed wire channel 312a.Therefore, by arranging the glue injection groove 311, the glue injection groove 311 can be filled with the sealing glue to seal the end of each of the first wire passage channel 312a and the second wire passage channel 312b away from the heating body 240 to prevent leakage of the liquid.

[0055] Referring to [Fig. 3], in some embodiments, the atomizer further comprises a liquid absorption element 500. The liquid absorption element 500 is disposed on the side of the base 320 opposite the protruding structure 312. The liquid absorption element 500 may be made of materials with a high liquid adsorption capacity, such as materials similar to those of the liquid guide element. In this way, the liquid dripping from the protruding structure 312 can be collected in the liquid absorption element 500, thus preventing the condensate liquid from flowing onto the electronic equipment and damaging the aerosol-generating device.

[0056] Referring to [Fig. 1], in some embodiments, the basic component 300 further comprises a sealing element 310, and the sealing element 310 comprises a projecting structure 312. The projecting structure 312 is disposed towards the atomizing component 200. In the embodiment of [Fig. 1], the projecting structure 312 is inserted into the atomizing component 200 by the end of the atomizing component 200 furthest from the mist outlet pipe 120, and in some other embodiments, the projecting structure 312 is sheathed on the outer peripheral side of the atomizing component 200. Both disposition arrangements allow the basic component 300 to be connected by insertion to the end of the atomizing component 200 furthest from the mist outlet pipe 120. The The first seals the inner peripheral side of the liquid guide element, and the second seals the adjustment gap between the atomizing component 200 and the base component 300. Both improve the seal.

[0057] With reference to Figures 1 and 11, in some embodiments, the atomizer further includes a liquid injection cap 600. The housing 110 is provided with a liquid injection hole communicating with the mounting cavity 130, and the liquid injection cap 600 is positioned to cover the liquid injection hole. In this way, when the liquid in the liquid storage compartment 140 is insufficient, the liquid injection cap 600 can be opened to inject liquid into the liquid storage compartment 140. This allows the atomizer to be used repeatedly. In some other embodiments, the atomizer is not provided with the liquid injection cap 600; as a disposable product, it is convenient for the user.

[0058] In some embodiments, during assembly, the atomizing component 200 and the base component 300 can be supplied first; the atomizer is in the state as in [Fig. 13], and it can be seen at that time that the atomizer consists of three modules, namely the liquid cup 100, the atomizing component 200 and the base component 300. One end of the atomizing component 200 is connected by insertion to the mist outlet pipe 120; first, the atomizing component 200 is connected by insertion to the mist outlet pipe 120; and the base component 300 is connected by insertion to the housing 110 to cover the cup mouth. Once the base component 300 is connected by insertion to the housing 110, the base component 300 is indeed obviously connected by insertion to the atomizing component 200. We can see that thanks to the modular design, the assembly of the atomizer can be more convenient.

[0059] In some other embodiments, during assembly, one end of the atomizing pipe 210 can be inserted into the end of the mist outlet pipe 120 away from the mist outlet orifice 121 to form a first assembled body 710, and after the assembly of the base component 300, the liquid guide element is connected by insertion to the base component 300 to form a second assembled body 720; the atomizer state is mounted in [Fig.14], the second assembled body 720 is inserted into the first assembled body 710 along the axial direction of the atomizing pipe 210 through the cup mouth to complete the atomizer assembly.This means that the second assembled body 720 is simply inserted into the first assembled body 710 via the cup opening to connect the base component 300 to the liquid cup 100. Simultaneously, the liquid guide element is assembled onto the atomizing tube 210 to complete the assembly. As you can see, the atomizer can be modularized. in the first assembled body 710 and the second assembled body 720, which also feature a high degree of modularity, thus making atomizer assembly more convenient.

[0060] With reference to [Fig. 1], the atomizer provided in the embodiments of this application comprises a liquid cup 100, an atomizing component 200, and a sealing element 310. One end of the liquid cup 100 is provided with a mist outlet orifice 121; in the embodiment in which the mist outlet tube 120 is provided, the mist outlet orifice 121 is located at one end of the mist outlet tube 120 (see [Fig. 1]); and in the embodiment in which the mist outlet tube 120 is not provided, the mounting hole on the housing 110 can serve as the mist outlet orifice 121. The atomizing component 200 comprises an atomizing tube 210, a liquid guide element, and a heating element 240.The heating element 240 is disposed within the liquid guide element, and the liquid guide element is used to guide the liquid towards the heating element 240. The atomizing tube 210 is sheathed on the outer peripheral side of the liquid guide element and is provided with a liquid inlet 211. The atomizing tube 210 communicates with the mist outlet 121. The sealing element 310 comprises a support portion 314 and a projecting structure 312. The support portion 314 abuts against the inner wall of the liquid cup 100, and the support portion, the liquid cup 100, and the atomizing tube 210 enclose each other to form the liquid storage compartment 140. The liquid storage compartment 140 communicates with the liquid guide element by via the liquid inlet orifice 211.The projecting structure 312 is arranged to pass through the support portion 314 and extends into the liquid guide element via the end of the liquid guide element furthest from the mist outlet 121, such that the projecting structure 312, the atomizing pipe 210, and the mist outlet 121 are connected to form a mist outlet channel. The projecting structure 312 fits at least partially against the inner wall of the liquid guide element, and a first gap 312c is formed at the point of contact.The first gap 312c can be formed by a fit between the liquid guide element and the protruding structure 312; however, an airflow channel can form even if the liquid guide element and the protruding structure 312 are butted together, because the liquid guide element and the protruding structure 312 are made of different materials, resulting in a difference in their absorption capacity. When air must pass through the fit between the liquid guide element and the protruding structure 312, the liquid is subjected to forces. Due to the different absorption properties of the protruding structure 312 and the liquid guide element, it can very easily overcome the adsorption of the liquid guide element and the protruding structure 312. The liquid-free airflow channel then forms in a thin layer on the inner peripheral side of the liquid guide element abutting the protruding structure 312, i.e., the first space 312c. The liquid guide element is at least partially separated from the support portion 314 to form a second space. The first space 312c is in communication with the second space to form an air inlet channel which communicates the mist outlet channel with the liquid storage compartment 140. Referring to [Fig.2], the air inlet channel can absorb air from the air path of the atomizing component 200 or the protruding structure 312 and transmit it to the liquid storage compartment 140.The need for this design stems from the fact that the liquid in the storage cavity is gradually consumed by the user, thus increasing the volume of the storage cavity. If the liquid storage cavity is no longer replenished with air, the initial air volume will increase, and the air pressure will decrease. When the air pressure in the liquid storage compartment 140 falls below atmospheric pressure, the air within the compartment can create a suction effect, drawing liquid towards the storage compartment. This prevents the liquid from being transferred to the heating element 240 through the liquid guide element. Consequently, the liquid reaching the heating element 240 will be insufficient, the heating element will overheat, and the liquid guide element will burn out.Therefore, by placing the first 312c space and the second space in communication with each other, the 140 liquid storage compartment can be replenished with air in a timely manner, thus avoiding negative pressure and improving the atomizer's liquid supply capacity.

[0061] Referring to [Fig. 5], in certain embodiments, the end face of the liquid guide element opposite the support portion 314 is butted against the support portion 314. In this way, the support portion 314 can provide support for the liquid guide element, thus improving the stability of the liquid guide element's attachment. The face of the support portion 314 opposite the liquid guide element is provided with an air vent groove 314a, which forms the second space. This also ensures the formation of the second space and can guarantee the liquid supply capacity of the soil-generating device.

[0062] Referring to [Fig.4], in certain embodiments, the air exhaust groove 314a extends along the radial direction of the protruding structure 312. The atomizing pipe 210 has a projection onto the sealing portion, and the air exhaust groove 314a extends outwards from the projection in the radial direction of the projecting structure 312. It can be seen in [Fig. 4] that the projecting structure 312 has a projection along its axial direction onto the support portion 314, and such a projection cannot cover the air exhaust groove 314a, which ensures a sufficient length of the air exhaust groove 314a, i.e., a sufficient ventilation length to ensure that air enters the liquid storage compartment 140 smoothly.

[0063] Referring to [Fig. 5], in certain embodiments, a plurality of air exhaust grooves 314a are arranged and distributed at regular intervals in the circumferential direction of the protruding structure 312. Thus, during use of the atomizer, although the user may use the atomizer at different angles, the air exhaust grooves 314a are present at all angles for air exhaust, thereby ensuring the stability of the atomizer. This prevents inefficient air exhaust at certain angles. However, referring to [Fig.7], in some embodiments the air exhaust groove 314a is not provided and the support portion 314 and the end face of the liquid guide element close to the support portion 314 are spaced apart to form the second space.

[0064] Referring to Figures 1 and 2, in certain embodiments, the liquid guide element comprises a first liquid guide element 220 and a second liquid guide element 230. The atomizing tube 210 is sheathed on the outer peripheral side of the first liquid guide element 220. The first liquid guide element 220 is sheathed on the outer peripheral side of the second liquid guide element 230. The heating element 240 is disposed in the second liquid guide element 230. The radial outer peripheral side of the protruding structure 312 fits into the radial inner peripheral side of the first liquid guide element 220 to form the first space 312c.The end face of the projecting structure 312, offset from the support portion 314, fits against the end face of the second liquid guide element 230 to form a third space, and this third space communicates with the first space 312c. The principle by which the projecting structure 312 fits against the first liquid guide element 220 to form the first space 312c is identical to the principle above by which the projecting structure 312 fits against the liquid guide element to form the first space 312c, and will not be repeated here. The principle for forming the third space can be identical to the principle for forming the first space 312c. However, an air groove extending radially from the second projecting structure 312 can be disposed on the face. The end of the projecting structure 312 is positioned opposite the second liquid guide element 230, and the air groove connects the air channel in the projecting structure 312 with the first space 312c, thus using the air groove to form a third space. The arrangement of this third space can provide the air inlet channel entering the liquid storage compartment 140 with improved air intake.

[0065] Referring to [Fig. 1], in certain embodiments, the sealing element 310 further comprises a first extension portion 315. The first extension portion 315 is disposed on the peripheral side of the support portion 314 and extends away from the liquid storage compartment 140. This is equivalent to fitting a skirt to the support portion 314. The outer peripheral side of the first extension portion 315 is butted against the inner wall of the liquid cup 100.This is equivalent to widening the contact area between the support portion 314 and the inner wall of the liquid cup 100, so that when the liquid enters the adjustment gap between the support portion 314 and the liquid cup 100, once the support portion 314 is pierced, the first extension portion 315 also provides a sealing effect, thus preventing the liquid from leaking and improving the sealing effect.

[0066] Referring to [Fig. 5], in certain embodiments, a projecting rib 315a is disposed on the outer peripheral side of the first extension portion 315, and the projecting rib 315a extends in the circumferential direction of the first extension portion 315 and encloses the first extension portion 315. When the outer peripheral side of the first extension portion 315 is abutted against the inner wall of the liquid cup 100, the projecting rib 315a is also abutted against the inner wall of the liquid cup 100. However, since the projecting rib 315a protrudes from the first extension portion 315 in the radial direction of the first extension portion 315, the pressure between the projecting rib 315a and the liquid cup 100 will be greater than the pressure between the other parts of the first portion of extension 315 and the liquid cup 100.This allows the protruding rib 315a to better seal the fit between the first extension portion 315 and the liquid cup 100, thus improving the sealing effect.

[0067] Referring to [Fig. 9], in certain embodiments, the liquid guide element comprises a first liquid guide element 220 and a second liquid guide element 230. The atomizing tube 210 is sheathed on the outer peripheral side of the first liquid guide element 220. The first liquid guide element 220 is sheathed on the outer peripheral side of the second liquid guide element 230. The heating element 240 is arranged in the second liquid guide element 230. The outer radial peripheral side of the protruding structure 312 fits into the inner radial peripheral side of the first liquid guide element 220 to form the first space 312c. The end face of the protruding structure 312, away from the support portion 314, fits into the end face of the second liquid guide element 230 to form the third space. The sealing element 310 further includes a thermal insulation sleeve 313, and the thermal insulation sleeve 313 is sheathed at the end of the protruding structure 312 near the second liquid guide element 230. In the embodiment of [Fig. 8] or 9, the protruding structure 312 and the reinforcing blade 316 are arranged as a single unit. In this way, the protruding structure 312 is made of the same material as the reinforcing blade 316, such as low heat resistance plastic.Therefore, the arrangement of the thermal insulation sheath 313 better separates the protruding structure 312 from the heating body, thus protecting the protruding structure 312. Furthermore, referring to [Fig.

[10] , the thermal insulation sheath 313 can also extend along the axial direction of the protruding structure 312 towards the direction near the base 320. In this way, the first feed wire channel 312a and the second feed wire channel 312b can be arranged in the thermal insulation sheath 313. It will be easily understood that, compared to the embodiment of [Fig. 1], in the embodiment of [Fig. 1], the thermal insulation sheath 313 is not provided at the end of the protruding structure 312, while in the embodiment of [Fig. 9], the thermal insulation sheath 313 is provided at the end of the protruding structure 312 near the second liquid guide element 230.

[0068] Referring to [Fig. 1] or 11, in some embodiments, the atomizer further comprises a liquid injection plug 600; the wall of the liquid cup 100 is also provided with a liquid injection hole; the liquid injection hole is connected to the liquid storage compartment 140, and the liquid injection plug 600 is positioned to cover the liquid injection hole. In this way, when the liquid in the liquid storage compartment 140 is insufficient, the liquid injection plug 600 can be opened to inject liquid into the liquid storage compartment 140. This allows the atomizer to be used repeatedly.

[0069] Referring to [Fig.1], in some embodiments, the liquid injection hole and the second space are arranged at an interval in the axial direction of the atomizing component 200. In this way, when injecting the liquid, it is not easy for the liquid to enter the second space; therefore, the liquid flows from the second space to the first space 312c, and finally flows into the air channel in the atomizing component 200 and causes leakage.
