[0028] The technical solutions in the embodiments of the present application will be described clearly and completely by the following description with reference to the attached figures. Obviously, the described embodiments are only a part of the embodiments of the present application, instead of being exhaustive for the present application. Other embodiments based on the embodiments of the present application and obtained by a person skilled in the art without creative work should be included within the scope of protection of the present application.

[0029] The embodiments of the present application provide an atomizer, a method of assembling the same, and an aerosol generating device to solve the problem of complicated assembly of existing atomizers. It will be described hereinafter with reference to the accompanying figures.

[0030] The atomizer provided in the embodiments of the present application can be used in an aerosol generating device. The aerosol generating device may comprise an atomizer and a central unit, and the central unit may comprise mechanisms such as a control mechanism and a power supply mechanism. After the atomizer is connected to the central unit of the aerosol generating device, the power supply mechanism of the central unit supplies electric power to the atomizer, so that the power supply mechanism can supply electric power to the atomizing component of the atomizer, thereby enabling the atomizing component to generate heat, the specific heat generation mode of the atomizing component depending on the type of the 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 supplies a variable magnetic field to the atomizing component to excite the atomizing component to generate a vortex current to produce heat. A control component in the central unit of the aerosol generating device may be provided with a microphone. When the atomizer is connected to the central unit, the microphone may be in communication with the mist outlet pipe, allowing the microphone to detect the flow rate of the air in the mist outlet pipe, so as to control the power supply mechanism to supply the atomizing component with electric power corresponding to the flow rate of the air in the mist outlet pipe.

[0031] Referring to [Fig.l], the atomizer provided in the embodiments of the present application comprises a liquid cup 100, an atomizing component 200 and a base component 300. Wherein the liquid cup 100 may comprise a housing 110 and a mist outlet pipe 120, and one end of the mist outlet pipe 120 is provided with a mist outlet port 121. The mist outlet pipe 120 is connected to the housing by one end of the mist outlet port 121.The atomizing component may include a first end and a second end that are arranged opposite each other, and the first end of the atomizing component may be fitably connected to the end of the mist outlet pipe 120 away from the mist outlet 121; a base component, including a protruding structure 312 and a support portion that are connected to each other, the protruding structure 312 is fitably connected 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 121, wherein the protruding structure 312 may be made of materials such as silica gel and rubber.In some 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.

[0032] In particular, referring to [Fig. 13], in some specific embodiments, a mounting cavity 130 is provided inside the housing 110, the housing 110 is further provided with a cup mouth and a mounting hole 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 hole and is provided with a mist outlet hole 121, and the other end of the mist outlet pipe 120 extends along the direction where the cup mouth is located. In fact, in the embodiment in which the mist outlet pipe 120 is not provided, the mounting hole can directly act as the mist outlet hole 121. As shown in [Fig.l], the edge of the mounting hole and the edge of the mist outlet hole 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 bonding or interlocking once formed independently. One end of the atomizing component 200 is connected by insertion to the mist outlet pipe 120, as shown in [Fig.l], 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 inserted into the liquid guide member of the atomizing component 200. The end of the base component 300 close to the mist outlet pipe 120 is . connected by insertion to the end of the atomizing component 200 away from the mist outlet pipe 120; also, as shown in [Fig.l], the base component 300 is provided with a protruding structure 312, the protruding structure 312 is inserted into the liquid guide member 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.

[0033] Referring to [Fig.l], 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 the prior art, the atomizing component 200 is mounted in the mist outlet pipe 120), but is only insertionally connected to the mist outlet pipe 120, therefore, the atomizing component 200 is not necessarily mounted in a narrow space of 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 at a predetermined position, which makes the assembly difficult, the assembly efficiency low and the consistency low.On the other hand, the length of the mist outlet pipe 120 has been shortened, in fact, if the atomizing component 200 is mounted in the mist outlet pipe 120, the end of the mist outlet pipe 120 far from the mist outlet port 121 must extend to the base component 300, which makes the assembly easier even if the mist outlet pipe 120 and the housing 110 are arranged separately from each other and must 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 is, the more the mounting gap at the end far from the mist outlet port 121 will be amplified.In addition, 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 firstly 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 modularization higher and the assembly more convenient (See below for a description of the assembly method of the atomizer).

[0034] Referring to [Fig.l], in some embodiments, the atomizing component 200 comprises an atomizing pipe 210, a liquid guiding member and a heating body 240. The heating body 240 is disposed on the inner side of the liquid guiding member, the liquid guiding member comprises a first liquid guiding member 220 and a second liquid guiding member of liquid 230, as shown in [Fig. 3], the heating body 240 may be disposed on the inner peripheral side of the second liquid guide member 230 or in some other embodiments, the heating body 240 is wrapped inside the second liquid guide member 230, or if the second liquid guide member 230 is not provided, and only the first liquid guide member 220 is provided, the atomizing component 200 may be disposed on the inner peripheral side of the first liquid guide member 220 or wrapped by the first liquid guide member 220. The atomizing pipe 210 is sheathed on the outer peripheral side of the liquid guide member. Wherein, the atomizing pipe 210 is insertably connected to the end of the mist outlet pipe 120 away from the mist outlet port 121 and is in communication with the mist outlet pipe 120.The end of the base component 300 close to the mist outlet pipe 120 is insertably disposed at the end of the liquid guide member far from the mist outlet pipe 120 and fits the inner peripheral side of the end of the liquid guide member far from the mist outlet pipe 120. This can improve the sealing of the atomizer, i.e., prevent the leakage of the liquid from the liquid storage compartment 140 through the atomizing component 200. In particular, the liquid guide member guides the liquid from the liquid storage compartment 140 under the action of capillary action and disperses it over the entire atomizing component 200.Since the heating body 240 is disposed in the liquid guide member, it obviously comes into contact with the liquid of the liquid guide member, therefore, when the heating body 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 member is not perfectly uniform, because under the action of gravity, the liquid has a tendency to gather in the direction of the gravity orientation, 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 member approaches the support portion 314.Therefore, the liquid that gathers at the position where the liquid guide member approaches the support portion 314 can easily break free from the constraint of the liquid guide member and flow out of the liquid guide member. However, the end of the base component 300 close to the mist outlet pipe 120 is insertably disposed at the end of the liquid guide member far from the mist outlet pipe 120 and fits to the inner peripheral side of the end of the liquid guide member far from the mist outlet pipe. 120, which prevents the liquid from leaking from the liquid guide member at the level close to the support portion 314, thereby improving the sealing of the atomizer. The structure of the base component 300 which is inserted into the mist outlet pipe 120 may be shown in [Fig. 4] as a protruding structure 312, the protruding structure 312 may be in a tubular shape, and in other embodiments, the protruding structure 312 may also be in other irregular shapes. In addition, it should be noted that the atomizer and the aerosol generating device are often portable in actual use, so they will inevitably be placed by the user at different postures. Therefore, in many cases, the atomizer is not in the upright position as shown in [Fig. 3], but may be placed horizontally or even upside down.However, when the user uses the atomizer, he usually places the atomizer at the vertical position similar to that shown in [Fig. 3], because when the user inhales the aerosol, he often lowers his head to inhale, instead of raising his head. And when the user inhales the aerosol, a large amount of liquid in the liquid guide member will be consumed and turned into atomized vapor, then is mixed with air to produce an aerosol and finally discharged from the mist outlet 121. Therefore, the liquid guide member is continuously replenished with liquid from the liquid storage compartment 140, so that when the user uses it, the liquid flow on the liquid guide member is the most violent, and thus easily causes the liquid to overflow from the liquid guide member.Therefore, when the atomizer is held in the vertical position as shown in [Fig. 3] (i.e., at this position, the mist outlet direction of the atomizer and the direction of gravity are approximately reversed), which provides a sealing effect at the end of the liquid guide member close to the support portion 314, thereby greatly improving the sealing effect of the atomizer. The part of the base component 300 inserted into the liquid guide member fits without clearance or at least partially fits with clearance to the inner peripheral side of the liquid guide member. This is due to the high surface tension of the liquid, which makes it possible to provide a sealing effect even in the case of the clearance fit. The adjustment mode can be selected according to the actual situation.

[0035] Referring to [Fig.l], in some embodiments, the base component 300 comprises a protruding structure 312 and a support portion 314, and one end of the protruding structure 312 extends in the direction close to the mist outlet pipe 120 to be inserted at the end of the liquid guide member far from the mist outlet pipe 120. The protruding structure 312 may 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 enclose to form the liquid storage compartment 140. The support portion 314 can also be made of soft rubber like the protruding structure 312, thereby improving 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 fit clearance 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 being arranged to pass through the support portion 314. The protruding structure 312 and the support portion 314 can be formed integrally, so that no fit clearance exists between the protruding structure 312 and the support portion 314, thereby preventing the liquid from leaking out of the liquid storage compartment 140 through a fit clearance between the protruding structure 312 and the support portion 314.But in some embodiments, the protruding structure 312 and the support portion 314 are arranged separately from each other, which will be described in more detail later.

[0036] Referring to [Fig.l], in some embodiments, the liquid guide member comprises a first liquid guide member 220 and a second liquid guide member 230. The first liquid guide member 220 and the second liquid guide member 230 are both tubular in shape. The first liquid guide member 220 may be made of a material such as a fibrous material or a porous body, wherein the fibrous material may be: plant fiber, animal fiber, mineral fiber, and synthetic fiber.The first liquid guide member 220 may be made of a material such as cotton, a non-woven fabric, a glass fiber material, a porous ceramic material, and a porous metal material; the second liquid guide member 230 may be made of a material such as a fibrous material or a porous body, wherein the fibrous material may be: plant fiber, animal fiber, mineral fiber, and synthetic fiber. The second liquid guide member 230 may be made of a material such as cotton, a non-woven fabric, a glass fiber material, a porous ceramic material, and a porous metal material. The atomizing pipe 210 is sheathed on the peripheral side. outer side of the first liquid guide member 220, the first liquid guide member 220 is sheathed on the outer peripheral side of the second liquid guide member 230, and the heating body 240 is disposed in the second liquid guide member 230. In this way, the liquid must pass through the first liquid guide member 220 to enter the second liquid guide member 230, and then contacts the heating body 240, which extends the liquid path distance, improves the blocking effect of the liquid guide member on the liquid, and reduces the risk of leakage of the liquid piercing the surface of the liquid guide member (especially the second liquid guide member 230).The end of the base component 300 close to the mist outlet pipe 120 is insertably disposed at the end of the first liquid guide member 220 away from the mist outlet pipe 120, and the end face of the base component 300 close to the mist outlet pipe 120 is abutted at least partially against the end face of the second liquid guide member 230. In this way, when the user uses the atomizer, the lower end of the second liquid guide member 230 is sealed in the gravity direction, thereby preventing the liquid from piercing the surface of the second liquid guide member 230 and leaking here, improving the liquid sealing effect, further strengthening the second liquid guide member, preventing the detachment and deformation of the second liquid guide member, and prolonging the service life of the second liquid guide member.

[0037] Referring to [Fig.l], in some embodiments, the base component 300 further comprises a first extension portion 315. One end of the first extension portion 315 is connected to the side of the support portion 314 close to 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 abuts against the inner wall of the housing 110, which is equivalent to widening the contact surface between the support portion 314 and the inner wall of the liquid cup 100, so that when the liquid enters the fitting clearance between the support portion 314 and the liquid cup 100, after the support portion 314 is pierced, the first extension portion 315 also provides a sealing effect, thereby preventing the leakage of the liquid and improving the sealing effect.

[0038] Referring to [Fig. 2], in some embodiments, the base component 300 further comprises a reinforcing blade 316. The reinforcing blade 316 is arranged to bear against the side of the support portion 314 spaced 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, e.g. For example, the reinforcing blade 316 is made of laminar steel or hard plastic, and the supporting portion 314 is made of soft rubber. The supporting portion 314 can provide a good sealing effect, and the reinforcing blade 316 helps to avoid deformation of the supporting portion 314. The deformation of the supporting portion 314 will cause the supporting portion 314 cannot be abutted against the inner wall of the liquid cup 100 and thus cause the liquid to leak, therefore, improving the sealing effect of the reinforcing blade 316.

[0039] Referring to Figures 2, 6 and 8, in some embodiments, for example the embodiment of [Fig. 2], the reinforcing blade 316 surrounds the end of the protruding structure 312 away from the mist outlet pipe 120, the protruding structure 312 protrudes from the side of the reinforcing blade 316 away from the support portion 314, as shown in Figures 2 and 6, the protruding structure 312 protruding from the side of the reinforcing blade 316 away from the support portion 314, and the end of the protruding structure 312 protruding from the reinforcing blade 316 may form a liquid collection ring 3121. Referring to [Fig.2], the lower portion of the liquid collecting ring 3121 is lower than the lower portion of the reinforcing blade 316, in other words, the side of the liquid collecting ring 3121 spaced away from the second liquid guide member 230 protrudes relative to the side of the reinforcing blade 316 spaced away from the second liquid guide member 230, and the liquid collecting ring 3121 can prevent the condensate liquid from flowing to the position where the reinforcing blade 316 is located, thereby improving the sealing effect and effectively preventing leakage. During 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 gather at the liquid collection ring 3121, instead of further flowing outward along 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 liquid reaches a certain level, the droplets drip. Since the condensate droplets are suspended on the liquid collection ring 3121, the falling position of the condensate droplets is essentially at the projection point of the liquid collection ring 3121 on the base 320. A drainage channel or a liquid absorption member 500 mentioned below may be provided here, and the condensate liquid may be discharged from the atomizer or absorbed by the liquid absorption member 500, so as to prevent the condensate liquid from flowing to other elements and causing damage. For example, a common risk of the condensate liquid is that it flows to the microphone of the aerosol generating device and damages the microphone.

[0040] 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 integrally formed. Further referring to [Fig. 9], the protruding structure 312 and the reinforcing blade 316 are integrally formed here, thereby forming a stronger support structure, i.e., it fixes the end of the atomizing component 200 close to the base 320 on the one hand, and fixes the support portion 314 on the other hand. At this time, the protruding structure 312 and the reinforcing blade 316 may be made of a hard material such as plastic or metal (including alloys) to provide a good support effect.

[0041] Referring to [Fig. 8], in some embodiments, an air exhaust groove 314a is provided on the side of the support portion 314 facing the liquid storage compartment 140, and the air exhaust groove 314a extends along the radial direction of the protruding structure 312 from the junction between the protruding structure 312 and the support portion 314 toward the direction away from the protruding structure 312 to the liquid storage compartment 140. This is equivalent to communicating the fit between the protruding structure 312 and the liquid guide member with the liquid storage compartment 140, thereby forming an airway.When the amount of liquid in the liquid storage compartment 140 decreases, the liquid storage compartment 140 is replenished with air through the air path to balance the air pressure and avoid excessive negative pressure in the liquid storage compartment 140 which will cause the liquid to not flow to the heating body 240. See below for a description on the first space 312c.

[0042] Referring to [Fig. 2], in some embodiments, the end of the atomizing pipe 210 facing the base component 300 is at least partially spaced from the support portion 314 to form a liquid inlet 211 that communicates the liquid guide member 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 211 is arranged here so as 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 body 240 is spaced from the liquid inlet 211 in the axial direction of the atomizing pipe 210, and when the user uses the atomizer, the heating body 240 is higher than the liquid inlet orifice 211.This means that in order for the liquid to reach the heating body 240, it must first overcome gravity and rise in the liquid guide element to the heating body 240. This allows . to partially weaken the pushing effect of the liquid contained in the liquid storage compartment 140 on the liquid contained in the liquid guide member and to prevent the leakage of the liquid that pierces the surface of the liquid guide member under excessive pressure in the liquid guide member. In the embodiment of [Fig.l], the protruding structure 312 is also used to seal the inner peripheral side of the liquid guide member, thereby further improving the sealing effect.

[0043] Referring to [Fig.l], in some embodiments, along the axial direction of the atomizing pipe 210, the height of the liquid inlet 211 from the support portion 314 is a. The penetration depth of the protruding structure 312 into the liquid guide member is b. a and b satisfy a constraint l.5a< b<10a. When bel.5a, the protruding structure 312 provides only a poor support effect to the atomizing component 200, and the atomizing component 200 shakes, causing the liquid to leak.And when b>10a, the heating body 240 is lifted (this is because the heating body 240 cannot be shaded by the protruding structure 312, but must be exposed to the atomization channel formed by communicating the protruding structure 312, the atomization component 200 and the mist outlet pipe 120), therefore, the liquid is difficult to reach the heating body 240, which causes the heating body 240 to be burned and damages the heating body 240. And when b is within the above range, it is possible to overcome the above problems.

[0044] Referring to Figures 1 and 11, in some 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 member 310, and the base 320 can be inserted into the mounting cavity 130 through the cup mouth, thereby enabling the base component 300 to be insertably connected to the liquid cup 100. The sealing member 310 comprises the protruding structure 312 and the support portion 314, and the sealing member 310 is disposed on the side of the base 320 facing the atomizing component 200. The first electrode 410 and the second electrode 420 are spaced apart from each other and are both disposed to pass through the base 320.The protruding structure 312 is provided with a forward wire passage channel that passes through the protruding structure 312 along the axial direction of the protruding structure 312, wherein the forward wire passage channel may comprise a first forward wire passage channel 312a and a second forward wire passage channel 312b. The first electrode 410 may be electrically connected to the heating body 240 by passing through the first forward wire passage channel 312a. The second electrode 420 may be electrically connected to the heating body 240 by passing through the second forward wire passage channel. forward wire passage 312b. One of the first electrode 410 and the second electrode 420 can be connected to the positive pole of the heating body 240, and the other can be connected to the negative pole of the heating body 240. The first electrode 410 and the second electrode 420 are actually structures electrically connecting the atomizer to the central unit of the aerosol generating device. Generally, two contacts (or pins) extend from the central unit; when the atomizer is partially connected to the central unit, the two contacts contact the first electrode 410 and the second electrode 420 respectively to realize an electrical connection. In the traditional aerosol generating device, the forward wires of the positive and negative poles of the heating body 240 are suspended in the mist outlet channel and contact each other, which will cause a short circuit.In the embodiments provided in the present application, the forward wires of the two poles of the heating body 240 are respectively arranged in the first forward wire passage channel 312a and the second forward wire passage channel 312b, so as to ensure that they are spaced apart from each other without short circuit. In addition, referring to FIGS. 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 and the electrode ring 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 may also be in the form of a conventional electrode, provided that the first electrode 410 and the second electrode 420 are spaced apart from each other.

[0045] Referring to [Fig. 6], in some embodiments, the sealing member 310 is provided with a glue injection groove 311 on the side spaced from the atomizing component 200. The first forward wire passage channel 312a and the second forward wire passage channel 312b pass through the bottom of the glue injection groove 311. Obviously, one end of each of the first forward wire passage channel 312a and the second forward wire passage channel 312b is in communication with the liquid guide member, because the heating body 240 is disposed in the liquid guide member. Therefore, the liquid can leak along the first forward wire passage channel 312a or the second forward wire passage channel 312b.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 forward wire passage channel 312a and the second forward wire passage channel 312b away from the heating body 240 to prevent leakage of the liquid.

[0046] 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 facing the protruding structure 312 and is disposed opposite the protruding structure 312. The liquid absorption member 500 may be made of materials with high liquid adsorption capacity, such as materials similar to the materials of the liquid guide member. In this way, the liquid dripping from the protruding structure 312 can be collected in the liquid absorption member 500, thereby preventing the condensate liquid from flowing to the electronic equipment and damaging the aerosol generating device.

[0047] Referring to [Fig. 1], in some embodiments, the base component 300 further comprises a sealing member 310 and the sealing member 310 comprises a protruding structure 312. The protruding structure 312 is disposed toward the atomizing component 200. In the embodiment of [Fig. 1], the protruding structure 312 is inserted into the atomizing component 200 by the end of the atomizing component 200 away from the mist outlet pipe 120, and in some other embodiments, the protruding structure 312 is sheathed on the outer peripheral side of the atomizing component 200. Both arrangement modes enable the base component 300 to be insertably connected to the end of the atomizing component 200 away from the mist outlet pipe 120.The former is used to seal the inner peripheral side of the liquid guide member, and the latter is used to seal the fit between the atomizing component 200 and the base component 300. Both improve sealing.

[0048] Referring to Figures 1 and 11, in some embodiments, the atomizer further comprises a liquid injection plug 600. The housing 110 is provided with a liquid injection hole in communication with the mounting cavity 130, and the liquid injection plug 600 is arranged to cover the liquid injection hole. In this way, when the liquid contained in the liquid storage compartment 140 is insufficient, the liquid injection plug 600 can be opened to inject the 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 plug 600, as a disposable product, it is convenient for the user to use.

[0049] The first method of assembling an atomizer provided in the embodiments of the present application is applied to the above atomizer or aerosol generating device, referring to [Fig. 15], the method of assembling an atomizer comprises the following steps: S10, providing the atomizing component 200 and the base component 300; S20, insertably connecting one end of the atomizing component 200 to the mist outlet pipe 120; and S30, insert-connect the base component 300 to the housing 110 to cover the cup mouth.

[0050] At the end of step S10, the atomizer is in the state like [Fig. 13], and it can be seen at this time that the atomizer consists of three modules, namely the liquid cup 100, the atomizing component 200 and the base component 300. In step S20, firstly, the atomizing component 200 is insertably connected to the mist outlet pipe 120; and in step S30, after the base component 300 is insertably connected to the housing 110, indeed, the base component 300 is obviously insertably connected to the atomizing component 200. It can be seen that due to the modular design, the assembly of the atomizer can be more convenient.

[0051] The second method for assembling an atomizer provided in the embodiments of the present application is applied to the above atomizer or aerosol generating device. In the atomizer to which the present method is applied, the atomizing component 200 comprises an atomizing pipe 210, a liquid guiding member, and a heating body 240; the heating body 240 is disposed in the liquid guiding member; the atomizing pipe 210 is sheathed on the outer peripheral side of the liquid guiding member. The present method comprises: SOI, inserting one end of the atomizing pipe 210 into the end of the mist outlet pipe 120 away from the mist outlet 121 to form a first assembled body 710, completing the assembly of the base component 300, and insertably connecting the liquid guide member to the base component 300 to form a second assembled body 720; and S02, insert the second assembled body 720 into the first assembled body 710 along the axial direction of the atomizing pipe 210 through the cup mouth to complete the assembly of the atomizer.

[0052] At the end of step S01, the atomizer is in the state like [Fig. 14], it can be seen that it is sufficient to insert the second assembled body 720 into the first assembled body 710 through the cup mouth to obviously insertably connect the base component 300 to the liquid cup 100, and at the same time, the liquid guide member is assembled on the atomizing pipe 210 to complete step S02, i.e., complete the assembly. It can be seen that the atomizer can be modularized into the first assembled body 710 and the second assembled body 720, which also have a high degree of modularity, thus making the assembly of the atomizer more convenient.

[0053] Referring to [Fig.l], the atomizer provided in the embodiments of the present application comprises a liquid cup 100, an atomizing component 200 and a sealing member 310. One end of the liquid cup 100 is provided with a mist outlet port 121, in the embodiment in which the mist outlet pipe 120 is provided, the mist outlet port 121 is disposed at one end of the mist outlet pipe 120 (see [Fig.l]); and in the embodiment in which the mist outlet pipe 120 is not provided, the mounting hole on the housing 110 can act as the mist outlet hole 121. The atomizing component 200 comprises an atomizing pipe 210, a liquid guiding member, and a heating body 240. The heating body 240 is disposed in the liquid guiding member, and the liquid guiding member is used to guide the liquid to the heating body 240. The atomizing pipe 210 is sheathed on the outer peripheral side of the liquid guiding member, and the atomizing pipe 210 is provided with a liquid inlet hole 211.The atomizing pipe 210 is in communication with the mist outlet 121. The sealing member 310 comprises a support portion 314 and a protruding structure 312. The support portion 314 is abutted against the inner wall of the liquid cup 100 and the support portion, the liquid cup 100 and the atomizing pipe 210 enclose to form the liquid storage compartment 140. The liquid storage compartment 140 is in communication with the liquid guide member via the liquid inlet port 211. The protruding structure 312 is arranged to pass through the support portion 314 and extends into the liquid guide member through the end of the liquid guide member away from the mist port 121, so that the protruding structure 312, the atomizing pipe 210 and the mist outlet port 121 are in communication to form a fog outlet channel.The protruding structure 312 at least partially fits the inner wall of the liquid guide member, and a first gap 312c is formed at the fitting level. The first gap 312c may be formed by a fitting clearance between the liquid guide member and the protruding structure 312; however, an airflow channel may be formed even if the liquid guide member and the protruding structure 312 are abutted against each other because the liquid guide member and the protruding structure 312 are made of different materials, causing a difference in the absorption capacity of the two.When air is to pass through the fitting level between the liquid guide member and the protruding structure 312, the liquid being subjected to different absorption forces of the protruding structure 312 and the liquid guide member, it can very easily overcome the adsorption of the liquid guide member and the protruding structure 312, and then the air flow channel without liquid is formed in a thin layer on the inner peripheral side of the liquid guide member abutting against the protruding structure 312, namely the first gap 312c. The liquid guide member is at least partially spaced 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 that communicates the mist outlet channel with the liquid storage compartment 140. Referring to [Fig. 2], the air inlet channel can absorb air from the airway of the atomizing component 200 or the protruding structure 312 and transmit it to the liquid storage compartment 140. The necessity of such a design is that the liquid contained in the liquid storage cavity is gradually consumed with the use by the user, thereby enlarging the space of the liquid storage cavity. If the liquid storage cavity is no longer replenished with air, the initial air volume in the liquid storage cavity will increase and the air pressure will decrease.When the air pressure in the liquid storage compartment 140 is lower than atmospheric pressure, the air in the liquid storage compartment 140 can produce a liquid suction effect to the liquid storage compartment, which prevents the liquid from being transmitted to the heating body 240 through the liquid guide member. In this way, the liquid received by the heating body 240 is insufficient, the heating body 240 will be overheated, and the liquid guide member will be burned. Therefore, by arranging the first space 312c and the second space in communication with each other, the liquid storage compartment 140 can be replenished with air in time, thereby avoiding negative pressure and improving the liquid supply capacity of the atomizer.

[0054] Referring to [Fig.5], in some embodiments, the end face of the liquid guide member facing the support portion 314 is abutted against the support portion 314. In this way, the support portion 314 can provide support to the liquid guide member, thereby improving the fixing stability of the liquid guide member. And the face of the support portion 314 facing the liquid guide member is provided with an air exhaust groove 314a which forms the second gap. This also ensures the formation of the second gap and can ensure the liquid supply capacity of the soil generating device.

[0055] Referring to [Fig. 4], in some embodiments, the air exhaust groove 314a extends along the radial direction of the protruding structure 312. The atomizing pipe 210 has a projection on the sealing portion, and the air exhaust groove 314a protrudes from the projection outward in the radial direction of the protruding structure 312. It can be seen from [Fig. 4] that the protruding structure 312 has a projection along its axial direction on the supporting portion 314, and such a projection cannot cover the air exhaust groove 314a, which ensures a sufficient length of the air exhaust groove 314a, is a sufficient ventilation length to ensure that air smoothly enters the liquid storage compartment 140.

[0056] Referring to [Fig.5], in some embodiments, a plurality of air exhaust grooves 314a are provided and the plurality of air exhaust grooves 314a are 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 provided at all angles for air exhaust, thereby ensuring the stability of the atomizer. This avoids 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 member close to the support portion 314 are spaced apart from each other to form the second gap.

[0057] Referring to Figures 1 and 2, in some embodiments, the liquid guide member comprises a first liquid guide member 220 and a second liquid guide member 230. The atomizing pipe 210 is sheathed on the outer peripheral side of the first liquid guide member 220. The first liquid guide member 220 is sheathed on the outer peripheral side of the second liquid guide member 230. The heating body 240 is disposed in the second liquid guide member 230. The radial outer peripheral side of the protruding structure 312 fits the radial inner peripheral side of the first liquid guide member 220 to form the first gap 312c.The end face of the protruding structure 312 spaced from the support portion 314 fits the end face of the second liquid guide member 230 to form a third space, and the third space is in communication with the first space 312c. The principle by which the protruding structure 312 fits the first liquid guide member 220 to form the first space 312c is the same as the above principle by which the protruding structure 312 fits the liquid guide member to form the first space 312c, and will not be repeated here. The principle of forming the third space may be the same as the principle of forming the first space 312c.However, an air groove extending along the radial direction of the second protruding structure 312 may be provided on the end face of the protruding structure 312 facing the second liquid guide member 230, and the air groove communicates the air path in the protruding structure 312 with the first gap 312c, so that the air groove is used to form a third gap. The provision of the third gap can make the air inlet channel that enters the liquid storage compartment 140 have a better air inlet effect.

[0058] Referring to [Fig.l], in some embodiments, the sealing member 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 in a direction away from the liquid storage compartment 140. This is equivalent to providing a skirt for the support portion 314. The outer peripheral side of the first extension portion 315 abuts against the inner wall of the liquid cup 100.This is equivalent to expanding the contact surface between the support portion 314 and the inner wall of the liquid cup 100, so that when the liquid enters the fitting clearance between the support portion 314 and the liquid cup 100, after the support portion 314 is pierced, the first extension portion 315 also provides a sealing effect, thereby preventing leakage of the liquid and improving the sealing effect.

[0059] Referring to [Fig. 5], in some embodiments, a protruding rib 315a is provided on the outer peripheral side of the first extension portion 315 and the protruding rib 315a extends along 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 abuts against the inner wall of the liquid cup 100, the protruding rib 315a also abuts against the inner wall of the liquid cup 100. However, since the protruding rib 315a protrudes from the first extension portion 315 along the radial direction of the first extension portion 315, the pressure between the protruding rib 315a and the liquid cup 100 is greater than the pressure between the protruding rib 315a and the liquid cup 100. liquid 100 will be greater than the pressure between the other parts of the first extension portion 315 and the liquid cup 100.This enables the protruding rib 315a to better seal the fit between the first extension portion 315 and the liquid cup 100, thereby improving the sealing effect.

[0060] Referring to [Fig.9], in some embodiments, the liquid guide member comprises a first liquid guide member 220 and a second liquid guide member 230. The atomizing pipe 210 is sheathed on the outer peripheral side of the first liquid guide member 220. The first liquid guide member 220 is sheathed on the outer peripheral side of the second liquid guide member 230. The heating body 240 is disposed in the second liquid guide member 230. The radial outer peripheral side of the protruding structure 312 fits the radial inner peripheral side of the first liquid guide member 220 to form the first gap 312c. The end face of the protruding structure 312 spaced from the support portion 314 fits the end face of the second liquid guide member 230 to form the third gap. The sealing member 310 further comprises athermal insulation sheath 313, and the thermal insulation sheath 313 is sheathed at the end of the protruding structure 312 close to the second liquid guide member 230. In the embodiment of [Fig. 8] or 9, the protruding structure 312 and the reinforcing blade 316 are arranged integrally. In this way, the protruding structure 312 is made of the same material as that of 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, which protects the protruding structure 312. In addition, referring to [Fig. 10], the thermal insulation sheath 313 may also extend along the axial direction of the protruding structure 312 towards the direction close to the base 320.In this way, the first forward wire passage channel 312a and the second forward wire passage channel 312b can be arranged in the thermal insulation sheath 313. It will be easily understood that, compared with the embodiment of [Fig.l], in the embodiment of [Fig.l], the thermal insulation sheath 313 is not provided at the end of the protruding structure 312, in the embodiment of [Fig.9], the thermal insulation sheath 313 is provided at the end of the protruding structure 312 close to the second liquid guide member 230. .

[0061] Referring to [Fig.l] 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 in communication with the liquid storage compartment 140, and the liquid injection plug 600 is arranged 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 the liquid to the liquid storage compartment 140. This allows the atomizer to be used repeatedly.

[0062] Referring to [Fig.l], 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 to enter the second space for the liquid, therefore, the liquid flows from the second space to the first space 312c, and finally flows into the airway in the atomizing component 200 and causes the leakage.

[0063] Referring to [Fig.l], the atomizer provided in the embodiments of the present 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 other 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 pipe 210, a liquid guiding member and a heating body 240. In which the heating body 240 is arranged in the liquid guiding member, the atomizing pipe 210 is in communication with the mist outlet port 121 and is sheathed on the outer peripheral side of the liquid guiding member, the atomizing pipe 210 is provided with a liquid inlet port 211 for communicating the liquid guiding member with the liquid storage compartment 140. The base component 300 comprises a base 320 and a sealing member 310. The base 320 is arranged to cover the cup mouth. The sealing member 310 is mounted to the base 320 and extends along a side close to the mist outlet 121 to be inserted at the end of the liquid guide member remote from the mist outlet 121.The sealing member 310, the atomizing pipe 210, and the mist outlet 121 are in communication to form a mist outlet channel. The sealing member 310 at least partially fits the inner wall of the liquid guide member to seal the radial inner face of the liquid guide member. The liquid guide member guides the liquid contained in the liquid storage compartment 140 to the heating body 240 under the action of capillary action. Therefore, the liquid guide member is normally filled with liquid. However, the liquid volume is not evenly distributed in the liquid guide member. The liquid has a tendency to gather in the direction of gravity orientation. The atomizer is generally in the upright position shown as [Fig.l], that is, the direction of the airflow in the mist outlet channel approaches the reverse direction of gravity. Therefore, the liquid in the liquid guide member generally gathers at the end of the liquid guide member toward the base 320. Therefore, the sealing member 310 at least partially fits the inner wall of the liquid guide member to seal the radial inner surface of the liquid guide member, thereby improving the sealing and preventing leakage. In addition, the sealing member 310 can be fitted to the inner wall of the liquid guide member in a butting manner or at a gap. This is due to the high surface tension of the liquid, which greatly prevents the radial flow of the liquid toward the inside of the liquid guide member even when they are spaced apart.

[0064] Referring to [Fig.l], in some embodiments, the sealing member 310 further comprises a protruding structure 312 and an extension portion 314. The support portion 314 is abutted 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 at the end of the liquid guide member away from the mist outlet 121. In this way, the end face of the end of the sealing member 310 facing the base 320 is in the liquid storage compartment 140 and does not need to be sealed, and no leakage of the liquid occurs therefrom. The support portion 314 also improves the sealing effect of the liquid storage compartment 140 and avoids direct leakage of the liquid from a fit clearance between the base component 300 and the liquid cup 100.

[0065] Referring to [Fig. 12], in some embodiments, the end of the atomizing pipe 210 close to the support portion 314 is provided with a plurality of abutting portions 212 arranged protruding along the axial direction of the atomizing pipe 210, and the abutting portions 212 abut against the support portion 314. In this way, the support portion 314 can provide support to the end of the atomizing pipe 210 close to the support portion 314 and thus improves the fixing effect of the atomizing component 200. The plurality of abutting portions 212 are arranged at regular intervals to form a plurality of liquid inlet ports 211, and the plurality of liquid inlet ports 211 are distributed at regular intervals in the circumferential direction of the atomizing pipe 210.This allows liquid to enter the liquid guide member 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 pipe 210 close to the support portion 314 is arranged at an interval with the support portion 314 to form a liquid inlet port 211. Such a structure is simple and simplifies the manufacture of the atomizing pipe 210. In addition, the length of the liquid inlet port 211 in the circumferential direction of the atomizing pipe 210 reaches the maximum (i.e., it is equal to the circumference of the atomizing pipe 210), thereby ensuring that liquid enters the liquid guide member from all directions and improving the liquid supply capacity.

[0066] Referring to [Fig.l], in some embodiments, the sealing member 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 in a direction away from the liquid storage compartment 140. The outer peripheral side of the first extension portion 315 abuts against the inner wall of the liquid cup 100. In this way, when the liquid passes through a fit 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.

[0067] In some embodiments, the protruding structure 312 passes through a reinforcing blade 316 and protrudes from the side of the reinforcing blade 316 spaced from the support portion 314. That is, as shown in FIGS. 2 and 6, the protruding structure 312 protrudes from the side of the reinforcing blade 316 spaced from the support portion 314, the end of the protruding structure 312 protruding from the reinforcing blade 316 may form a liquid collection ring 3121. During 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 gather at the liquid collection ring 3121, instead of still flowing outward according to the radial direction from the protruding structure 312 to the reinforcing blade 316. In this way, the condensate is controllable.In particular, when the volume of the condensate liquid reaches a certain level, the droplets drip. Since the condensate droplets are suspended on the liquid collection ring 3121, the falling position of the condensate droplets is essentially at the projection point of the liquid collection ring 3121 on the base 320. A drainage channel or a liquid absorption member 500 mentioned below may be provided here, and the condensate liquid may be discharged from the atomizer or absorbed by the liquid absorption member 500, so as to prevent the condensate liquid from flowing to other elements and causing damage. For example, a common risk of the condensate liquid is that it flows to the microphone of the aerosol generating device and damages the microphone.

[0068] Referring to [Fig.l], in some 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 along the direction where the support portion 314 is located. The outer peripheral side of the second extension portion 322 abuts against the first extension portion 315, so that the first extension portion 315 can be better abutted against the inner wall of the liquid cup 100, thereby improving the sealing effect. The end face of the second extension portion 322 away from the cover body 321 can be abutted against the reinforcing blade 316.In this way, support can be provided to the reinforcing blade 316 and the fixing effect of the reinforcing blade 316 can be improved.

[0069] Referring to [Fig.4], in some embodiments, an air exhaust groove 314a is provided on the side of the support portion 314 facing the liquid storage compartment 140, and the exhaust groove air outlet 314a extends toward the direction 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 liquid storage compartment 140 using a second gap between the liquid guide member and the protruding structure 312, thereby avoiding 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 member.

[0070] Referring to [Fig.l], in some embodiments, the liquid guide member comprises a first liquid guide member 220 and a second liquid guide member 230; the atomizing pipe 210 is sheathed on the outer peripheral side of the first liquid guide member 220; the first liquid guide member 220 is sheathed on the outer peripheral side of the second liquid guide member 230; the heating body 240 is disposed in the second liquid guide member 230; the radial outer peripheral side of the protruding structure 312 abuts against the radial inner peripheral side of the first liquid guide member 220; the end face of the protruding structure 312 spaced from the support portion 314 abuts against the end face of the second liquid guide member 230.In this way, the radial inner side of the first liquid guide member 220 and the end face of the second liquid guide member 230 facing the protruding structure 312 are sealed simultaneously, thereby improving the sealing effect for the liquid.

[0071] The atomizer is a part of the aerosol generating device for generating an aerosol, so it is provided with an atomizing component for atomizing a liquid to be atomized and mixing it with air to generate an aerosol to be supplied to the user. Generally, the atomizing component of the traditional atomizer is mounted directly in the mist outlet pipe, and then the mist outlet pipe is mounted to the liquid cup by gluing or fitting. On the one hand, the inner space of the atomizing pipe is narrow and the atomizing component is difficult to mount in place; on the other hand, the atomizing pipe must pass through the liquid cup and then fit a mounting structure on the surface of the liquid cup, for this, a passage length is large and the assembly difficulty is high.It can be seen that the assembly of traditional atomizers is difficult, which makes the atomizer assembly efficiency low and the consistency poor. In order to make the atomizer assembly more efficient and consistent, an atomizer with easier assembly is needed.

[0072] For the atomizer provided in the embodiments of the present application, by arranging the mist outlet pipe on the liquid cup, connecting one end of the atomizing component to the end of the mist outlet pipe away from the mist outlet port, and connecting and fitting the second end of the atomizing component to the protruding structure of the base component, assembly of the atomizer is easier. Specifically, when the mist outlet pipe is arranged integrally with the housing, the abutment between the mist outlet pipe and the housing is not necessarily taken into account when assembling, thereby making assembly easier.When the mist outlet pipe is arranged separately with the housing, taking into account that the atomizing component is not arranged in the mist outlet pipe, but connected to the end of the mist outlet pipe far from the mist outlet port, the atomizing pipe does not extend independently to the base component, but extends to the base component by relay of the atomizing component. In this way, the length of the atomizing pipe is reduced and the assembly is less difficult. In addition, an atomizing core is connected to the mist outlet pipe and the base component by insertion, which avoids operations such as rotating the atomizing core when it is assembled to the mist outlet pipe (but rotation will be required for threaded connection), it is only necessary to push the atomizing core toward the mist outlet pipe according to the insertion direction.Similarly, for the assembly of the base component, it is sufficient to push the base component toward the atomizing core according to the insertion direction, which facilitates the assembly process. In summary, the aerosol generating device provided in the embodiments of the present application can make the assembly of the aerosol generating device easier.
