Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and more particularly to an atomizer; this invention also relates to an aerosol generating device having the above-mentioned atomizer. Background Technology

[0002] An electronic atomizing device is an electronic product that heats and atomizes liquids such as e-liquid or medicinal liquids into aerosols for inhalation; it can also be called an aerosol generating device.

[0003] An electronic atomizing device may include an atomizer and a power supply component, wherein the power supply component is used to supply power to the atomizer; the atomizer may include an atomizing core assembly and a liquid reservoir, wherein the atomizing core assembly is used to heat up and atomize liquid when powered on, and the liquid reservoir is used to supply the atomizing core assembly with the liquid to be heated and atomized.

[0004] Electronic atomizing devices typically use a porous ceramic body as a capillary liquid-conducting element to draw in a liquid matrix, and use a heating element placed on the atomizing surface of the porous ceramic body to heat at least a portion of the liquid matrix inside the porous ceramic body to generate an aerosol.

[0005] In related electronic atomization devices, electrode springs for conductive contact with the heating element are typically fixedly mounted in a structural component, and the elastic force of the electrode springs causes the free ends of the electrode springs to press against the conductive terminals of the heating element. Additionally, the support structure for housing and supporting the liquid-conducting element is typically made of integrally injection-molded plastic.

[0006] However, this method of fixing the electrode springs requires the electrode springs to be integrally injection molded with the plastic material, which increases the manufacturing process and consequently increases manufacturing costs. Moreover, since these supports are usually designed as container shapes with an open top and a closed bottom, and also include curved liquid inlet channels, it is difficult to demold the molded supports. Therefore, the mold design for molding such supports is relatively complex, which makes it difficult to improve the mass production of supports. Summary of the Invention

[0014] In a preferred embodiment, the number of the first electrode springs is two; the second support includes a spacer portion that separates the two first electrode springs.

[0015] In a preferred embodiment, the first support further includes a partition and a first chamber with an upper opening; the partition separates the first chamber and the receiving chamber, and the partition includes a first through hole communicating between the first chamber and the receiving chamber. The atomizing surface of the liquid guiding element faces the first chamber; the atomizing surface allows the aerosol to escape and enter the first chamber through the first through hole.

[0016] In a preferred embodiment, the first support includes a liquid channel that extends downward from the upper end of the first support and communicates with the receiving chamber from the side, thereby enabling the liquid matrix to flow to the liquid-absorbing surface of the liquid guiding element.

[0017] In a preferred embodiment, the atomizer includes a first seal, at least a portion of which is located between the liquid guiding element and the inner wall of the receiving chamber, for sealing and isolating the atomizing surface and the liquid-absorbing surface.

[0018] In a preferred embodiment, the first seal further includes a sealing bottom covering a portion of the surface of the fluid guiding element, and the second bent portion abuts against the sealing bottom.

[0019] In a preferred embodiment, an electrode through hole is provided on the side wall, and the first bent portion passes through the electrode through hole and enters the receiving chamber.

[0020] In a preferred embodiment, the liquid guiding element has a channel extending through it, and at least a portion of the inner surface of the liquid guiding element defining the channel constitutes the liquid absorption surface.

[0021] In a preferred embodiment, the atomizer further includes a main housing defining a liquid containment space and having an aerosol channel located within the main housing. The first support is connected to the main housing, enabling the aerosol channel to deliver the generated aerosol.

[0022] The present invention also employs the following technical solution to solve its technical problem: an aerosol generating device, comprising an atomizer for atomizing a liquid matrix to generate an aerosol, and a power supply component for supplying power to the atomizer; the atomizer includes any one or more of the atomizers described above.

[0023] The beneficial effects of this invention are as follows: In the atomizer of this embodiment, by configuring the first electrode spring to include a first bent portion, a connecting portion, and a second bent portion connected in sequence, and by having the first bent portion extend into the receiving chamber, and the second bent portion located on one side of the liquid guiding element and used to provide support for the liquid guiding element so that the liquid guiding element is held in the receiving chamber, the liquid guiding element can be suspended in the receiving chamber by the first electrode spring. Correspondingly, the first electrode spring can also be mounted on the first bracket, thus eliminating the need to fix this first electrode spring to other components as an integral structure, which reduces the manufacturing process and thereby lowers manufacturing costs.

[0035] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them.

[0036] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0037] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] See Figure 1 and Figure 2 The diagram shows two three-dimensional assembly schematics of an atomizer 200 provided in an embodiment of the present invention. The atomizer 200 can store a liquid matrix, which is used to heat and vaporize the liquid matrix to generate an aerosol when powered on. The atomizer 200 can be combined with a power supply component to form an aerosol generating device that can be directly used by the user. The liquid matrix can be, for example, e-liquid, medicinal liquid, or other liquids; in this document, the liquid matrix can also be referred to as a liquid, vaporization can also be referred to as atomization, and the aerosol can also be referred to as smoke, mist, or atomizing gas.

[0039] See Figures 3 to 6 As shown, it is Figure 1 The diagram shows two cross-sectional views and two exploded perspective views of the atomizer 200. The atomizer 200 may include an atomizer core assembly 100 and a main housing 90. The main housing 90 defines a liquid containment space 91 and has an aerosol channel within the main housing 90 for fluid communication with the atomizer core assembly 100 and for discharging generated aerosols to the outside. For example, the aerosol channel may be defined by a vapor output conduit 92 having a free end 93. The main housing 90 is generally constructed as a hollow cylinder and has an intake port 94 at its proximal end; it also has an opening at its distal end, through which functional components are easily assembled within the main housing 90. The atomizer core assembly 100 is fitted into the main housing 90 to receive the liquid matrix from the liquid containment space 91.

[0040] See Figure 7 and Figure 8 As shown, this is a three-dimensional exploded view of the atomizing core assembly 100 in the atomizer 200. In some embodiments, combined with Figure 3 , Figure 7 and Figure 8 As shown, the atomizing core assembly 100 may include a liquid guiding element 10, a heating element 20, and a first support 30. The liquid guiding element 10 includes an atomizing surface 11 and a liquid absorption surface 12. The heating element 20 may be disposed on the atomizing surface 11 and is used, for example, to heat at least a portion of the liquid matrix absorbed by the liquid guiding element 10 to generate an aerosol when energized. The first support 30 includes a partition 31, a first chamber 32 having an upper opening 33, and a receiving chamber 34 having a lower opening 35. The partition 31 separates the first chamber 32 and the receiving chamber 34, and the partition 31 includes a first through hole 36 communicating between the first chamber 32 and the receiving chamber 34. The liquid guiding element 10 is at least partially housed in the receiving chamber 34, and the atomizing surface 11 faces the first chamber 32. The atomizing surface 11 allows the aerosol to escape and enter the first chamber 32 through the first through hole 36. For example, the first chamber 32 may be connected to the smoke output pipe 92 of the atomizer 200 so that the generated aerosol can be discharged through the smoke output pipe 92.

[0041] The liquid guiding element 10 can be fully housed in the receiving chamber 34, or it can be configured such that a portion of the atomizing surface 11 is located within the first through hole 36, or even within the first chamber 32.

[0042] The liquid guiding element 10 can be made of a material with capillary channels or pores, such as hard or rigid capillary structures like fiber cotton, porous ceramic body, glass fiber rope, porous glass ceramic, or porous glass.

[0043] The liquid guiding element 10 is in fluid communication with the liquid receiving space 91 to absorb the liquid matrix delivered from the liquid receiving space 91. The atomizing surface 11 of the liquid guiding element 10 may be its upper surface facing the flue gas output duct 92, which is preferably a plane extending along the cross-section of the main housing 90. The liquid absorbing surface 12 may be disposed opposite to the atomizing surface 11.

[0044] The heating element 20 can be a resistance heating element, and the aerosol generated by heating at least a portion of the liquid matrix absorbed by the liquid guiding element 10 can be released into the flue gas output pipe 92 after escaping from the atomizing surface 11. For example, the heating element 20 can be formed on the atomizing surface 11 of the liquid guiding element 10 by means of mounting, printing, deposition, etc. In some embodiments, the heating element 20 can be made of materials such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, and titanium. Figure 7As shown, the heating element 20 has a patterned conductive trajectory, such as meandering or meandering, and may include conductive terminals 21 at both ends; the conductive terminals 21 may be in the form of gaskets, and may have shapes such as square, round, or elliptical.

[0045] In some other embodiments, the heating element 20 may also be a non-contact infrared radiation heating element. In addition to incorporating the heating element 20 in the form of a resistance circuit or a stainless steel sheet onto the atomizing surface, the heating element 20 may also be at least partially embedded in the liquid guiding element 10, for example, at least partially embedded in the liquid guiding element 10 near the atomizing surface 11.

[0046] In the atomizer 200 of this embodiment, by configuring the first support 30 to include a partition 31, a first chamber 32 having an upper opening 33, and a receiving chamber 34 having a lower opening 35, it is convenient to place the liquid guiding element 10 from bottom to top in the receiving chamber 34 through the lower opening 35; moreover, for the first support 30 with this structure, the corresponding mold can easily demold the molded first support 30, thereby reducing the complexity of the mold used to mold the first support 30 and improving the mass production of the first support 30.

[0047] Furthermore, by aligning the atomizing surface 11 of the liquid guiding element 10 towards the flue gas output pipe 92, and positioning the atomizing surface 11 facing the intake port 94, the heating element 20 on the atomizing surface 11 generates heat. This allows the liquid on the atomizing surface 11 to absorb heat and atomize, producing smoke that does not need to bypass the liquid guiding element 10 itself. Instead, the smoke directly enters the intake channel of the flue gas output pipe 92 and reaches the intake port 94 for inhalation by the user. This reduces the loss of smoke as it passes around the atomizing core, ensuring sufficient smoke is effectively absorbed by the user per unit time, thereby increasing the effective smoke volume generated by the aerosol generator per unit time. Additionally, the relatively small distance between the atomizing surface 11 and the intake port 94 minimizes the path of the smoke to the intake port 94, further reducing smoke loss in the intake channel and ensuring an even greater effective smoke volume generated by the aerosol generator per unit time.

[0048] In some embodiments, combined with Figure 3 and Figure 7 As shown, a portion of the atomizing surface 11 is exposed to the first chamber 32 through the first through-hole 36 of the partition 31. For example, the atomizing surface 11 can be configured to face the first through-hole 36, such that the partition 31 corresponds to the edge portion of the atomizing surface 11, while the first through-hole 36 exposes most of the other surface of the atomizing surface 11, meaning that most of the surface of the atomizing surface 11 can be seen from the first chamber 32. In this way, the aerosol generated on the atomizing surface 11 can be discharged to the flue gas output pipe 92 through the first through-hole 36 and the first chamber 32.

[0049] In some embodiments, combined with Figure 3 and Figure 7 As shown, the heating element 20 is disposed on the exposed portion of the atomizing surface 11. In this way, the aerosol generated on the atomizing surface 11 can be directly discharged into the first chamber 32 through the first through-hole 36.

[0050] In some embodiments, combined with Figure 3 and Figure 7 As shown, the first support 30 also includes a liquid discharge channel 37, which extends downward from the upper end of the first support 30 and communicates with the receiving chamber 34 from the side, thereby enabling the liquid matrix to flow to the liquid absorption surface 12 of the liquid guiding element 10. The liquid discharge channel 37 communicates with the liquid receiving space 91 at its upper end and with the receiving chamber 34 at its lower end. For example, the liquid discharge channel 37 may form a side opening 37A on the side of the receiving chamber 34 near its lower end, thereby enabling communication with the receiving chamber 34. The side opening 37A may be arranged perpendicularly or obliquely relative to the atomizing surface 11. In this way, the liquid matrix conveyed downward through the liquid discharge channel 37 can flow laterally to the receiving chamber 34 through the side opening 37A, especially to the liquid absorption surface 12 of the liquid guiding element 10 within the receiving chamber 34.

[0051] In the above embodiment, by setting the liquid channel 37, for example, the liquid of e-liquid can enter the liquid guiding element 10 through the liquid channel 37, and be guided upward to the atomizing surface 11 of the liquid guiding element 10 for atomization through capillary action. The amount of e-liquid atomized is supplied entirely through capillary action, and the liquid will not leak downward during the process, so the anti-leakage effect is good.

[0052] In some embodiments, combined with Figure 3 and Figure 7 As shown, the atomizing coil 200 further includes a first sealing member 40, at least a portion of which is located between the liquid guiding element 10 and the inner wall 34A of the receiving chamber 34, for sealing and isolating the atomizing surface 11 and the liquid absorption surface 12. That is, the first sealing member 40 ensures that liquid supplied by the liquid receiving space 91 can only enter the liquid guiding element 10 through the liquid absorption surface 12 and then be delivered to the atomizing surface 11. The first sealing member 40 may be generally cup-shaped, allowing the liquid guiding element 10 to be accommodated within the recess of the cup-shaped first sealing member 40. The first sealing member 40 also has liquid inlets 44 on its left and right sidewalls, allowing the liquid absorption surface 12 to communicate with the outside through the liquid inlets 44, and thus connect to the liquid receiving space 91 during assembly. The first sealing member 40 may be made of sealing silicone material.

[0053] In some embodiments, combined with Figure 3 and Figure 8 As shown, the inner wall 34A of the receiving chamber 34 includes a first inclined surface 34B that is relatively longitudinally inclined. The first seal 40 includes a second inclined surface 41, and the first inclined surface 34B fits into the second inclined surface 41. For example, both the left and right sides of the receiving chamber 34 can gradually move away from the liquid guiding element 10 as they extend downwards, thereby making the receiving chamber 34 flared. In addition, the opening at the bottom of the receiving chamber 34 can have a uniform cross-sectional area. The outer contour of the first seal 40 can be approximately complementary to the shape of the receiving chamber 34 for a sealing fit. Thus, by providing the first inclined surface 34B and the second inclined surface 41, it is convenient to place the first seal 40, which houses the liquid guiding element 10, into the receiving chamber 34, and it is beneficial to enhance the seal between the liquid guiding element 10 and the first support 30; in addition, by opening the side opening 37A on the first inclined surface 34B, it is beneficial for the first support 30 to be demolded along the vertical stroke during manufacturing.

[0054] In some embodiments, combined with Figure 3 and Figure 7 As shown, the first seal 40 includes a first portion 42 that covers the edge portion 13 of the atomizing surface 11 and abuts against the partition 31. In this way, the liquid guiding element 10 can be fixedly held within the first seal 40; and, when installing the liquid guiding element 10, the first portion 42 of the first seal 40 abuts against the partition 31, preventing direct hard contact between the liquid guiding element 10 and the first support 30.

[0055] In some embodiments, combined with Figure 3 and Figure 7 As shown, the liquid guiding element 10 has a channel 14 extending through it, and at least a portion of the inner surface of the liquid guiding element 10 defining the channel 14 constitutes the liquid absorption surface 12. For example, the liquid guiding element 10 can be a square tube with a channel 14 extending through it from left to right. The liquid guiding element 10 can be square in shape, with a channel 14 extending through it from left to right; thus, the top surface of the liquid guiding element 10 can serve as an atomizing surface 11, and the upper surface of the channel 14 can serve as a liquid absorption surface 12; in addition, the left, right, and lower surfaces of the channel 14 can also serve as liquid absorption surfaces. The two openings at both ends of the channel 14 correspond to the liquid inlets 44 at the left and right ends of the first sealing member 40, respectively, and the two liquid inlets 44 correspond to the two side openings 37A of the first support 30, respectively. In this way, liquid matrix can be delivered into the liquid guiding element 10 from both left and right sides simultaneously.

[0056] In some embodiments, combined with Figure 3 , Figure 7 and Figure 8As shown, the cross-sectional area of ​​the first chamber 32 can be set to be smaller than the cross-sectional area of ​​the second chamber 34. For example, in the length direction of the atomizing surface 11, the length of the first chamber 32 can be smaller than the length of the second chamber 34; in this case, the thickness of the partition wall between the liquid channel 37 and the first chamber 32 can be thicker than the thickness of the partition wall between the liquid channel 37 and the second chamber 34; this length direction can be parallel to the extension direction of the channel 14. Alternatively or further, in the width direction of the atomizing surface 11, the length of the first chamber 32 can be smaller than the length of the second chamber 34. In this way, the distance between the wall of the first chamber 32 and the flue gas output pipe 92 can be minimized, thereby reducing the retention of continuously generated aerosols in the first chamber 32; correspondingly, the user can obtain a better smoke taste.

[0057] In some embodiments, combined with Figure 3 , Figure 7 and Figure 8 As shown, the atomizer 200 includes a second sealing element 50. The second sealing element 50 includes an inner cylinder portion 51 and an outer cylinder portion 52. The inner cylinder portion 51 is inserted into the first chamber 32 and fits snugly against the inner wall 32A of the first chamber 32. The outer cylinder portion 52 surrounds the upper end of the first support 30 and fits snugly against the outer wall of the upper end. The second sealing element 50 may also include a top through hole 54 and a top insertion hole 55, wherein the top through hole 54 is used to connect the liquid receiving space 91 and the lower liquid channel 37, and the top insertion hole 55 is used to allow the free end 93 of the flue gas output pipe 92 to be inserted therein. By providing the second sealing element 50, a seal is formed between the first support 30 and the main housing 90, so that the liquid matrix in the liquid receiving space 91 can only be transported to the suction surface 12 through the lower liquid channel 37.

[0058] In some embodiments, combined with Figure 3 and Figure 8 As shown, the inner cylinder 51 is also provided with a blocking arm 53 extending toward and adjacent to the atomizing surface 11. The blocking arm 53 can be used to reduce the retention of generated aerosols between the blocking arm 53 and the inner wall 32A of the first chamber 32. The blocking arm 53 can extend into the first through hole 36. By providing the blocking arm 53, the space between the blocking arm 53 and the inner wall 32A of the first chamber 32 is smaller, and the airflow tends to be less; thus, the aerosols generated on the atomizing surface 11 will basically not flow into the space between the blocking arm 53 and the inner wall 32A, thereby reducing the retention of continuously generated aerosols in this space; correspondingly, users can obtain a better smoke taste.

[0059] In some embodiments, combined with Figure 3 and Figure 7As shown, the heating element 20 has its heating portion located between the two blocking arms 53. The heating portion of the heating element 20 includes a wire located between two conductive terminals 21. In this manner, aerosols can be directly generated within the space between the two blocking arms 53, and then directly discharged into the flue gas output duct 92.

[0060] In some embodiments, combined with Figure 3 , Figure 7 and Figure 8 As shown, the first support 30 includes a sidewall 30A and a receiving chamber 34 with a lower opening 35. An electrode through-hole 30B is formed on the sidewall 30A. The atomizing core assembly 100 may further include a first electrode spring 60, which includes a first bent portion 61, a connecting portion 62, and a second bent portion 63 connected in sequence. Both the first bent portion 61 and the second bent portion 63 are bent relative to the connecting portion 62. After the liquid guiding element 10 is received in the receiving chamber 34, the first bent portion 61 can pass through the electrode through-hole 30B and enter the receiving chamber 34. The second bent portion 63 can be located on one side of the liquid guiding element 10 and provide support for the liquid guiding element 10 so that the liquid guiding element 10 is held in the receiving chamber 34. The first electrode spring 60 may be formed by bending a sheet-like metal substrate.

[0061] In some other embodiments, it is not necessary to provide an electrode through hole 30B on the side wall 30A; instead, other methods can be used to mount the first electrode spring 60 relative to the first bracket 30, as long as at least a portion of the first bent portion 61 extends into the receiving chamber 34 and contacts the heating element 20. For example, a groove can be formed by recessing the top of the first bracket 30 to allow the first bent portion 61 to pass through and enter the receiving chamber 34; or, the first bent portion 61 can be made to bypass the top of the first bracket 30 and enter the receiving chamber 34.

[0062] In the atomizing core assembly 100 of these embodiments, by configuring the first electrode spring 60 to include a first bent portion 61, a connecting portion 62, and a second bent portion 63 connected in sequence, and by extending the first bent portion 61 into the receiving chamber 34, and positioning the second bent portion 63 on one side of the liquid guiding element 10 to provide support for the liquid guiding element 10 so that the liquid guiding element 10 is held in the receiving chamber 34, the liquid guiding element 10 can be suspended in the receiving chamber 34 by the first electrode spring 60. Correspondingly, the first electrode spring 60 can also be mounted on the first bracket 30, thereby eliminating the need to fix the first electrode spring 60 to other components as an integral structure, which reduces the manufacturing process and thus reduces manufacturing costs.

[0063] In some embodiments, combined with Figure 7 and Figure 8 As shown, the free end 64 of the first bent portion 61 can press against the heating element 20. The free end 64 of the first bent portion 61 can serve as a conductive contact, thereby pressing against the conductive terminal 21 of the heating element 20 by means of the elasticity of the first electrode spring 60. There can be two first electrode springs 60, so that the two free ends 64 can respectively make conductive contact with the two conductive terminals 21 of the heating element 20 to realize the transmission of current.

[0064] In some embodiments, combined with Figure 7 and Figure 8 As shown, at least a portion of the width of the second bend 63 is greater than the width of the connecting portion 62. In this way, the support stability of the second bend 63 can be improved.

[0065] In some embodiments, combined with Figure 3 , Figure 5 , Figure 9 and Figure 10 As shown, where Figure 9 and Figure 10 for Figure 5 The diagram shows two exploded perspective views of the second support 70 and the second electrode spring 80 of the atomizer 200. The atomizing core assembly 100 includes the second support 70, on which the first support 30 is mounted. The second support 70 has a second electrode spring 80, and the first electrode spring 60 is electrically connected to the second electrode spring 80. For example, the two opposite outer sides of the first support 30 may have locking blocks, and the two opposite inner sides of the second support 70 may have locking grooves, thereby allowing them to be snapped together. The second electrode spring 80 can be injection molded integrally with the second support 70, and a portion of the second electrode spring 80 protrudes from the second support 70 to make conductive contact with, for example, the second bent portion 63 of the first electrode spring 60. The second electrode spring 80 may be formed by bending a sheet-like metal substrate.

[0066] In some embodiments, combined with Figure 3 , Figure 8 , Figure 9 and Figure 10 As shown, the second bending portion 63 includes a horizontal portion 65 and a downwardly extending portion 66. The horizontal portion 65 provides, for example, an upward supporting force to the fluid guiding element 10, and the downwardly extending portion 66 contacts the second electrode spring 80 on the second support 70. In this way, it is convenient to achieve a conductive connection between components through elastic contact after assembly is completed.

[0067] In some embodiments, combined with Figure 3 , Figure 6 , Figure 9 and Figure 10 As shown, a portion 81 of the second electrode spring 80 is exposed laterally on the second bracket 70 for conductive contact with the power supply component of the aerosol generating device. For example, a portion 81 of the second electrode spring 80 may be vertically oriented and exposed laterally on the second bracket 70 to facilitate conductive contact with the resilient conductive terminal of the power supply component. There may be two second electrode springs 80, which may be respectively disposed on the left and right sides of the second bracket 70, with the two exposed portions 81 arranged parallel to each other.

[0068] In some embodiments, combined with Figure 3 and Figure 9 As shown, there are two first electrode springs 60; the second bracket 70 includes a spacer 73 that separates the two first electrode springs 60. For example, the spacer 73 may extend upward from the bottom within the second bracket 70 and be located between the second bends 63 of the two first electrode springs 60. In this way, short circuits caused by contact between the two first electrode springs 60 can be prevented when the first electrode springs 60 and the first bracket 30 are mounted on the second bracket 70.

[0069] In some embodiments, combined with Figure 3 , Figure 6 , Figure 9 and Figure 10 As shown, the first seal 40 further includes a sealing bottom 43 covering a portion of the surface of the liquid guiding element 10, and the second bent portion 63 abuts against the sealing bottom 43. The sealing bottom 43 may be in the shape of a shallow container to accommodate the bottom of the liquid guiding element 10, thereby preventing liquid from leaking downward through the liquid guiding element 10. The elastic force of the first electrode spring 60 allows the second bent portion 63 to abut against the sealing bottom 43, thereby clamping the liquid guiding element 10 between the first bent portion 61 and the second bent portion 63 of the first electrode spring 60.

[0070] In some embodiments, combined with Figure 3 , Figure 9 and Figure 10 As shown, the second bracket 70 may have an air inlet 71, which communicates with the internal space 72 of the second bracket 70. For example... Figure 7 and Figure 8 As shown, a vent 30C may also be provided on the side wall 30A of the first bracket 30, the vent 30C connecting the outside of the first bracket 30 with the internal space of, for example, the receiving chamber 34. Thus, when the first bracket 30 is installed in the second bracket 70, the internal space 72 of the second bracket 70 can communicate with the internal space of the first bracket 30 through the vent 30C.

[0071] In one embodiment, combined with Figure 3 and Figure 8 As shown, the atomizer 200 may further include a main housing 90. The first support 30 is connected to the main housing 90, allowing the aerosol channel within the main housing 90 to deliver the generated aerosol. For example, the free end 93 of the smoke output pipe 92 of the main housing 90 can be inserted into the first chamber 32. In this way, the liquid matrix to be atomized can be provided to the atomizing core assembly 100 through the liquid containment space 91 defined by the main housing 90, and the generated aerosol can be delivered to the outside of the atomizer 200 through the smoke output pipe 92 for the user to inhale.

[0072] In one embodiment, with Figure 8 Similar to the baffle arm 53 shown, a baffle arm extending toward the atomizing surface 11 may also be provided on the free end 93 of the flue gas output duct 92. The baffle arm can be used to reduce the retention of generated aerosols between the baffle arm and the inner wall 32A of the first chamber 32. The baffle arm extends into the first through hole 36. In this embodiment, the second seal 50 may not have the aforementioned baffle arm 53.

[0073] For example Figure 1 and Figure 2 As shown, a sealing plug 95 can be inserted into the air inlet 94 of the atomizer 200, and a sealing sheet 96 can be attached to the air inlet 71 of the second bracket 70, so as to keep the atomizer 200 sealed before its first use and prevent liquid from leaking out.

[0074] The various components of the atomizer 200 of the present invention have been described above. When it is necessary to use the aerosol generating device for inhalation, the atomizer 200 can be connected to the power supply component first, and then the power switch of the power supply component can be turned on so that the power supply component can supply power to the atomizer 200. Then, when the user inhales into the mouthpiece where the inhalation port 94 of the atomizer 200 is located, the controller of the aerosol generating device can start the atomizer 200 to work according to the inhalation action, and finally produce the aerosol for the user to inhale. Among them, the liquid from the liquid containing space 91 is heated and atomized by the heating element 20 to form aerosol. The external air can flow sequentially through the air inlet 71, the internal space 72 of the second bracket 70 and the vent 30C of the first bracket 30, and then be delivered to the atomizing surface 11 of the liquid guiding element 10 in the first bracket 30, and then carry the formed aerosol out of the smoke output pipe 92.
