Abstract
Description
Technical Field
[0001] This application relates to the field of atomization technology, and more specifically, to an atomizer and an aerosol generating device. Background Technology
[0002] An aerosol generator is a small device that uses heat-not-burning (HNB) technology to generate aerosols from aerosol-producing products. In the atomizer of an aerosol generator using a high-viscosity aerosol-generating matrix, if a large portion of the matrix is consumed, leaving only a small amount, a large cavity forms above the atomizer's oil reservoir. At night, as the temperature drops, the pressure in this cavity decreases, and the negative pressure increases. To maintain the atomizer's vapor-liquid balance, outside air enters the cavity through the air passage, establishing a new equilibrium. During the day, as the temperature rises, the temperature inside the oil reservoir increases, the pressure in the cavity increases, and the negative pressure decreases. To maintain balance, the pressure in the oil reservoir forces the aerosol-generating matrix outwards. When this matrix is forced into the air passage, its high viscosity causes it to cool and solidify, clogging the air passage. This not only affects the normal operation of the aerosol generator but also the vaping experience. To address this issue of leakage and blockage in the cavity, the current industry solution is to wrap cotton around the heating element. This utilizes the cotton's ability to trap the aerosol-generating matrix to mitigate the effects of pressure changes. However, this measure leads to difficulties in ventilating the heating element, insufficient supply of the aerosol-generating matrix, and a burnt taste during suction, resulting in an unpleasant mouthfeel. Utility Model Content
[0003] This application provides an atomizer and an aerosol generating device, which at least solves the problems of difficult air exchange, insufficient supply of aerosol generating matrix, burnt taste, and poor taste during user inhalation.
[0004] The atomizer according to this application includes an atomizing base, a mouthpiece, a storage component, an air guide component, a heating element, and a locking component. The storage component is connected to the atomizing base and the mouthpiece at opposite ends, forming a receiving cavity together with the atomizing base and the mouthpiece. The air guide component is located within the receiving cavity and connected to the atomizing base. The air guide component has an internal cavity, and its sidewalls have a through hole and a connecting hole. The storage component, the atomizing base, the mouthpiece, and the air guide component form a first storage cavity, and the atomizing base and the air guide component form a second storage cavity. The first storage cavity and the second storage cavity are sequentially spaced apart in the direction from the mouthpiece to the atomizing base. The through hole is configured to connect the first storage cavity and the cavity. The connecting hole is configured to connect the first storage cavity and the second storage cavity. The heating element is housed within the receiving cavity. In the flow path of the aerosol generating matrix from the first storage cavity to the heating element, the locking member is located upstream of the heating element and is configured to prevent the aerosol generating matrix entering from the first storage cavity from flowing out.
[0005] In some embodiments, the air guide includes a first sub-part and a second sub-part connected to each other, the through hole and the connecting hole are located on the sidewall of the first sub-part, the cavity includes a first sub-cavity formed in the first sub-part, and the heating element is housed in the first sub-cavity. The locking member is housed in the first sub-cavity and is located between the sidewall of the first sub-part and the heating element.
[0006] In some embodiments, the air guide includes a first sub-part and a second sub-part connected to each other, the through hole and the connecting hole are located on the side wall of the first sub-part, the cavity includes a first sub-cavity formed in the first sub-part, and the heating element is housed in the first sub-cavity. The locking member is housed outside the cavity and sleeved on the outer side wall of the first sub-part.
[0007] In some embodiments, when the locking member is housed within the first sub-cavity and located between the side wall of the first sub-part and the heating element, the locking member is sleeved on the outer peripheral wall of the heating element and forms an integral atomizing module with the heating element.
[0008] In some embodiments, the connecting hole is a notch formed on the outer side wall of the first sub-part.
[0009] In some embodiments, the connecting hole is at least partially located inside the sidewall of the first sub-part, and one end of the connecting hole is open to communicate with the first storage cavity, while the other end of the connecting hole is open to communicate with the second storage cavity.
[0010] In some embodiments, the connecting hole is a straight through hole or a curved through hole.
[0011] In some embodiments, the locking element includes a locking element made of cotton, porous ceramic, porous polymer material, glass fiber, or polymer material.
[0012] In some embodiments, the heating element is a cylindrical structure, and the locking member is arranged around the heating element.
[0013] In some embodiments, the heating element is a flat plate structure, and the locking member is opposite to the liquid inlet surface of the heating element.
[0014] In some embodiments, the atomizer further includes a first sealing member disposed between the atomizing base and the end face of the heating element near the atomizing base. The first sealing member has a through hole penetrating both opposite ends. The mouthpiece has a through hole. The heating element has an atomizing chamber. The atomizing base has an air intake channel communicating with the outside. In the length direction of the atomizer, the through hole, the cavity, the atomizing chamber, the through hole, and the air intake channel are sequentially connected and together form a suction channel. The air intake channel communicates with the second storage chamber and together with the second storage chamber, the through hole, and the first storage chamber, forms an air exchange channel.
[0015] In some embodiments, the atomizer further includes a second seal disposed between the air guide and the mouthpiece to seal the gap between the air guide and the mouthpiece.

The atomizer further includes an electrical connector, which electrically connects the heating element to the battery assembly.
[0017] In the atomizer and aerosol generating device of this application, the locking member has the characteristic of locking the aerosol generating matrix. Its liquid-locking effect can be used to avoid the problem described in the background where the aerosol generating matrix enters the air passage and causes leakage and blockage due to pressure changes caused by temperature rise in the oil tank (first storage chamber). Simultaneously, the two ends of the connecting hole connect the first storage chamber and the second storage chamber respectively. When the first storage chamber is subjected to diurnal temperature variations, the aerosol generating matrix inside will depressurize primarily by leaking out through the connecting hole into the second storage chamber. Once depressurization is complete and a new equilibrium is reached, the aerosol generating matrix stored in the second storage chamber will be drawn back into the first storage chamber through the connecting hole under alternating air pressure conditions, or drawn back into the first storage chamber during atomization due to pressure changes within the first storage chamber. This effectively prevents the aerosol generating matrix from depressurizing by entering the air intake channel, thus avoiding blockage of the air intake channel and ensuring a good vaping experience for the user.

[0048] An aerosol generator is a small device that uses heat-not-burning (HNB) technology to generate aerosols from aerosol-producing products. In the atomizer of an aerosol generator using a high-viscosity aerosol-generating matrix, if a large portion of the matrix is consumed, leaving only a small amount, a large cavity forms above the atomizer's oil reservoir. At night, as the temperature drops, the pressure in this cavity decreases, and the negative pressure increases. To maintain the atomizer's vapor-liquid balance, outside air enters the cavity through the air passage, establishing a new equilibrium. During the day, as the temperature rises, the temperature inside the oil reservoir increases, the pressure in the cavity increases, and the negative pressure decreases. To maintain balance, the pressure in the oil reservoir forces the aerosol-generating matrix outwards. When this matrix is forced into the air passage, its high viscosity causes it to cool and solidify, clogging the air passage. This not only affects the normal operation of the aerosol generator but also the vaping experience. To address this issue of leakage and blockage in the cavity, current industry solutions involve wrapping the heating element with cotton. This utilizes the cotton's ability to trap the aerosol-generating matrix, mitigating the effects of pressure changes. However, this method leads to difficulties in ventilating the heating element, insufficient supply of the aerosol-generating matrix, and a burnt taste during inhalation, resulting in a poor flavor. To resolve this problem, this application provides an atomizer 100 (… Figure 1 (as shown) and an aerosol generating device 1000 having the atomizer 100 (as shown) and an aerosol generating device 1000 having the atomizer 100 Figure 10 (As shown).
[0049] Please refer to the following: Figure 1 , Figure 2 and Figure 5 The atomizer 100 of this application includes an atomizing base 10, a mouthpiece 20, a storage member 30, an air guide 50, a heating element 60, and a locking member 80. The opposite ends of the storage member 30 are connected to the atomizing base 10 and the mouthpiece 20 respectively, and together with the atomizing base 10 and the mouthpiece 20, they form a receiving cavity 101. The air guide 50 is located within the receiving cavity 101 and is connected to the atomizing base 10. The air guide 50 has an internal cavity 51, and its sidewalls have a through hole 53 and a connecting hole 55 (please refer to...). Figure 3 The storage component 30, atomizing base 10, nozzle 20, and air guide 50 form a first storage cavity 71, and the atomizing base 10 and air guide 50 form a second storage cavity 73. The first storage cavity 71 and the second storage cavity 73 are arranged alternately in the direction from the nozzle 20 to the atomizing base 10. Please refer to... Figure 7Through hole 53 is configured to connect the first storage cavity 71 and cavity 51. Connecting hole 55 is configured to connect the first storage cavity 71 and the second storage cavity 73. Heating element 60 is housed within receiving cavity 101. In the flow path of the aerosol generating matrix from the first storage cavity 71 to the heating element 60, locking member 80 is located upstream of the heating element 60 and is configured to prevent the aerosol generating matrix entering from the first storage cavity 71 from flowing out.
[0050] Specifically, please combine Figure 10 The atomizer 100 of this application is disposed in the aerosol generating device 1000 and is used to heat the aerosol generating matrix by energizing it, thereby generating an aerosol for the user to inhale. The heating method of the atomizer 100 to heat the aerosol generating matrix can be, but is not limited to, resistance heating, microwave heating or laser irradiation heating.
[0051] The aerosol generating apparatus 1000 is a structure capable of generating aerosols by heating an aerosol generating matrix. Aerosols can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which are typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol generating matrix is a processed product that, when heated, can generate aerosols. The aerosol generating matrix can be in a liquid state, or in a fully solid or semi-solid state. When the aerosol generating matrix is liquid, it is a mixed liquid containing dissolved substances such as nicotine and tobacco alkaloids, with solutes such as propylene glycol, vegetable glycerin, and pure water, and / or inorganic solutes. In this application, the aerosol generating matrix can be a high-viscosity e-liquid (e.g., sesame oil), which can generate aerosols when heated.
[0052] Please refer to the following: Figure 2 and Figure 5 The atomizer base 10 is a structure in the atomizer 100 used to support other components besides the atomizer base 100. In the embodiments of this application, the atomizer base 10 can be used to support the storage component 30, the air guide component 50, the heating element 60, and the locking component 80, etc. The atomizer base 10 includes a first end 11 and a second end 13 opposite to each other. The first end 11 of the atomizer base is provided with threads for connecting with the battery assembly 300 ( Figure 10 (As shown) Threaded connection, the second end 13 of the atomizing seat is used to connect with the storage component 30 and the air guide component 50.
[0053] The mouthpiece 20 is a structure in the atomizer 100 used for the user to inhale aerosol. The mouthpiece 20 has a through hole 21 for delivering the aerosol generated by the atomizer 100 heating the aerosol generation matrix to the user's mouth.
[0054] The storage component 30 is a structure used to store the aerosol generation matrix. The shape of the cross-section of the storage component 30 (the plane intercepted by a plane perpendicular to the longitudinal direction L of the atomizer 100; the meaning of "cross-section" is the same elsewhere in the text) can be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal shapes. The storage component 30 includes a first end 31 and a second end 33, which are opposite each other. The first end 31 of the storage component is connected to the second end 13 of the atomizer base, and the second end 33 of the storage component is connected to the mouthpiece 20. Thus, the mouthpiece 20, the storage component 30, and the atomizer base 10 together form a receiving cavity 101, in which the air guide 50, the heating element 60, and the locking element 80 are all located.
[0055] The air guide 50 is a structure used to deliver aerosol to the through hole 21 of the nozzle 20 and to fix the heating element 60. The air guide 50 can be made of a high-temperature resistant material. For example, the air guide 50 can be made of materials such as metal or ceramic, thus enabling it to guide high-temperature aerosols and extending its service life. Specifically, the air guide 50 includes a first end 501 and a second end 503. The first end 501 is connected to the second end 13 of the atomizing seat, and the second end 503 is connected to the nozzle 20. For details, please refer to [link to relevant documentation]. Figure 5 or Figure 7 In one example, the second end 13 of the atomizing base has an inner cylinder 17 and an outer cylinder 19. The outer cylinder 19 surrounds the inner cylinder 17, and a first gap 190 is formed between the outer cylinder 19 and the inner cylinder 17. The first end 501 of the air guide extends into the first gap 190 and forms a nested connection with at least one of the inner cylinder 17 and the outer cylinder 19. Furthermore, after the nested connection, it can be fastened by bonding with a press. The first end 31 of the storage member is sleeved on the outside of the outer cylinder 19 so that the first end 31 of the storage member is fixedly connected to the outer cylinder 19 of the atomizing base 10. At this time, the outer cylinder 19 is located between the first end 501 of the air guide and the first end 31 of the storage member.
[0056] The connection between the second end 503 of the air guide and the nozzle 20 includes at least one of the following: threaded connection, snap-fit connection, and adhesive connection. In this embodiment, the end of the nozzle 20 connected to the air guide 50 is provided with an inner layer 23 and an outer layer 25. The inner layer 23 surrounds the through hole 21, and the outer layer 25 surrounds the inner layer 23, with a second gap 250 formed between the outer layer 25 and the inner layer 23. The second end 503 of the air guide extends into the through hole 21 and is snap-fitted with the inner layer 23. The second end 33 of the storage member is sleeved on the outside of the outer layer 25, so that the second end 33 of the storage member is fixedly connected to the outer layer 25 of the nozzle 20.
[0057] Further, please refer to Figure 2In some embodiments, the atomizer 100 may further include a first fastener 41, which is sleeved on the outer side of the first end 31 of the storage component and the atomizing base 10. The first fastener 41 is interference-fitted with the first end 31 of the storage component and also interference-fitted with the outer side of the atomizing base 10, so as to make the storage component 30 and the atomizing base 10 more firmly connected. In addition, the first fastener 41 can be a metal ring, such as a copper ring or an aluminum ring, which can serve a decorative purpose.
[0058] Furthermore, please continue reading Figure 2 In some embodiments, the atomizer 100 may further include a second fastener 43, which is sleeved on the outside of the second end 33 of the storage member, and the second fastener 43 and the second end 33 of the storage member are press-fitted to make the storage member 30 and the mouthpiece 20 more securely connected. In addition, the second fastener 43 can be a metal ring, such as a copper ring or an aluminum ring, which can serve a decorative purpose.
[0059] Please refer to the following: Figure 2 and Figure 3 The air guide 50 has an internal cavity 51, and its sidewalls have a through hole 53 and a connecting hole 55. The cavity 51 is a spatial structure that passes through the first end 501 and the second end 503 of the air guide. The through hole 53 is a spatial structure on the sidewall of the air guide 50 that connects the external and internal cavity 51. Therefore, the central axis of the through hole 53 is usually located in a plane perpendicular to the length direction L of the atomizer 100, or the central axis of the through hole 53 forms a certain angle with this plane. Please refer to... Figure 9 The connecting hole 55 is a spatial structure on the side wall of the air guide 50 used to connect the first storage cavity 71 and the second storage cavity 73.
[0060] Please combine Figure 5 and Figure 8 The storage component 30, atomizing base 10, nozzle 20, and air guide 50 form a first storage cavity 71, and the atomizing base 10 and air guide 50 form a second storage cavity 73. The first storage cavity 71 and the second storage cavity 73 are sequentially spaced apart in the direction from the nozzle 20 to the atomizing base 10. The first storage cavity 71 is a spatial structure for storing the aerosol generating matrix. The aerosol generating matrix is typically stored in the first storage cavity 71. As the atomizer 100 is inhaled by the user, the aerosol generating matrix in the first storage cavity 71 tends to flow through the through hole 53 into the cavity 51.
[0061] The heating element 60 is a structure that generates heat when electricity is applied. The heating element 60 heats the aerosol-generating matrix located near it, causing the heated matrix to generate aerosols. The heating element 60 can be a porous ceramic material, typically prepared by mixing a ceramic slurry with a pore-forming agent and then sintering it. The sintered ceramic contains numerous micropores. The aerosol-generating matrix in the first storage chamber 71 can enter the porous ceramic through these micropores. When the heating element 60 generates heat, both the aerosol-generating matrix in contact with the heating element 60 and those entering the micropores will be heated and generate aerosols.
[0062] In some embodiments, the heating element 60 is housed within the cavity 51. In other embodiments, the heating element 60 is disposed outside the cavity 51. Regardless of whether the heating element 60 is disposed within or outside the cavity 51, the locking member 80 is located upstream of the heating element 60 in the flow path of the aerosol generating matrix from the first storage cavity 71 to the heating element 60. That is, the aerosol generating matrix in the first storage cavity 71 will pass through the locking member 80 first during its flow to the heating element 60.
[0063] The locking element 80 is a structure that can both guide and lock liquid. The locking element 80 has a porous structure, and the micropores within the porous structure can guide liquid. The locking element 80 includes locking elements made of cotton, porous ceramics, porous polymer materials, glass fiber, or other polymer materials.
[0064] Specifically, when the aerosol generating device 1000 is being normally drawn in, the aerosol generating matrix in the first storage chamber 71 first passes through the locking member 80. The aerosol generating matrix entering the locking member 80 then passes through the micropores in the locking member 80 and is guided towards the heating element 60, where it is heated to form an aerosol. Of course, because the size of the pores in the porous structure is relatively small, when the pressure in the first storage chamber 71 increases, compared to not having a porous structure upstream of the heating element 60, the porous structure upstream can prevent the aerosol generating matrix in the first storage chamber 71 from flowing unimpeded to the heating element 60. That is, the porous structure plays a role in preventing the aerosol generating matrix entering from the first storage chamber 71 from flowing out and flowing to the heating element 60, which is a liquid-locking effect.
[0065] In the atomizer 100 of this application embodiment, the locking member 80 has the characteristic of locking the aerosol generating matrix. Its liquid-locking effect can be used to avoid the leakage and blockage problem of the cavity 51 formed by the aerosol generating matrix entering the air passage due to the pressure change caused by the temperature rise in the oil tank (in the first storage chamber 71) as described in the background. Meanwhile, the two ends of the connecting hole 55 are respectively connected to the first storage chamber 71 and the second storage chamber 73. When the first storage chamber 71 is placed under the influence of the day and night temperature difference, the aerosol generating matrix in the first storage chamber 71 will be depressurized by first leaking out through the connecting hole 55 into the second storage chamber 73. When the depressurization is completed and a new equilibrium is reached, the aerosol generating matrix stored in the second storage chamber 73 will be drawn back into the first storage chamber 71 through the connecting hole 55 under the condition of alternating air pressure, or it will be drawn back into the first storage chamber 71 due to the air pressure change in the first storage chamber 71 during the atomization process. This can effectively prevent the aerosol generating matrix from depressurizing by entering the air intake channel 15 of the atomizing seat 10, which would cause the air intake channel 15 to become blocked, thus ensuring a good vaping experience for the user.
[0066] The atomizer 100 will be described in detail below with reference to the accompanying drawings.
[0067] Please see Figure 3 In some embodiments, the air guide 50 includes a first sub-part 57 and a second sub-part 59 that are connected to each other. A through hole 53 and a connecting hole 55 are located on the sidewall of the first sub-part 57. (Please refer to...) Figure 5 and Figure 8 The cavity 51 includes a first sub-cavity 571 formed in the first sub-part 57, and the heating element 60 is housed in the first sub-cavity 571. The locking member 80 is housed in the first sub-cavity 571 and is located between the side wall of the first sub-part 57 and the heating element 60.
[0068] Along the length L of the aerosol generating device 1000, the second sub-part 59 is located above the first sub-part 57 (viewed from the perspective of the aerosol generating device 1000 in its normal upright state). In this application, the second sub-part 59 is inserted into the through hole 21 of the suction nozzle 20 and engages with the inner layer 23 of the suction nozzle 20. The first sub-part 57 and the second sub-part 59 can be an integral structure, in which case the first sub-part 57 and the second sub-part 59 can be integrally formed, and the processing steps of the air guide 50 are relatively simple. The first sub-part 57 and the second sub-part 59 can also be separate structures. In this case, the first sub-part 57 and the second sub-part 59 can be detachably or non-detachably connected. Among them, the detachable installation method includes, but is not limited to, threaded connection, screw connection, or snap-fit connection. The non-detachable installation method includes, but is not limited to, welding, gluing connection, or interference fit. When the first sub-part 57 and the second sub-part 59 are detachably connected, if the first sub-part 57 (or the second sub-part 59) is damaged, only the first sub-part 57 (or the second sub-part 59) needs to be replaced, and the service life of the air guide 50 is relatively long.
[0069] Furthermore, in some embodiments, the first sub-section 57 and the second sub-section 59 have a stepped structure, and the cavity 51 also includes a second sub-cavity 591 formed in the second sub-section 59. Along the length L of the aerosol generating device 1000, the second sub-cavity 591 is closer to the nozzle 20. In some embodiments, the opening size of the second sub-cavity 591 is smaller than the opening size of the first sub-cavity 571, so that the cavity 51 is stepped. In this case, the heating element 60 is housed within the first sub-cavity 571, and the locking member 80 is housed within the first sub-cavity 571, located between the sidewall of the first sub-section 57 and the heating element 60. The stepped cavity 51 facilitates the accommodation and installation of the heating element 60 and the locking member 80, resulting in a high degree of integration among the air guide 50, the heating element 60, and the locking member 80.
[0070] Furthermore, in some embodiments, the locking member 80 is sleeved on the outer peripheral wall of the heating element 60 and forms an integrated atomizing module with the heating element 60. In this case, the atomizing module can be installed as a whole in the first sub-cavity 571. Compared with the atomizing module that is not integrated, the integrated atomizing module can be installed into the first sub-cavity 571 at once, making installation more convenient.
[0071] When the aerosol generating device 1000 is being normally drawn in, the aerosol generating matrix in the first storage chamber 71 first passes through the through hole 53 into the locking member 80. The aerosol generating matrix in the locking member 80 then passes through the micropores in the locking member 80 and is guided towards the heating element 60, where it is heated to form an aerosol. When the first storage chamber 71 is left to rest and is affected by the temperature difference between day and night, the aerosol generating matrix in the first storage chamber 71 leaks out through the connecting hole 55 into the second storage chamber 73. When the pressure relief is completed and a new equilibrium is reached, the aerosol generating matrix stored in the second storage chamber 73 will be drawn back into the first storage chamber 71 through the connecting hole 55 under alternating air pressure conditions, or it will be drawn back into the first storage chamber 71 during the atomization process due to the air pressure change in the first storage chamber 71. This effectively prevents the aerosol generating matrix from depressurizing by entering the air intake channel 15 of the atomizing seat 10, which would cause the air intake channel 15 to become blocked, thus ensuring a good vaping experience for the user.
[0072] In another embodiment, the heating element 60 is housed within the first sub-cavity 571, while the locking member 80 is housed outside the cavity 51 and fitted onto the outer side wall of the first sub-part 57. Similarly, the cavity 51 can be stepped. In this case, the heating element 60 is housed within the first sub-cavity 571, and the stepped cavity 51 facilitates the accommodating and mounting of the heating element 60. When the aerosol generating device 1000 is normally aspirated, the aerosol generating matrix in the first storage cavity 71 enters the locking member 80, and then, through the micropores in the locking member 80, is guided towards the heating element 60 and heated by the heating element 60 to form an aerosol. When the first storage chamber 71 is placed under the influence of day and night temperature differences, the aerosol generating matrix in the first storage chamber 71 will leak out from the connecting hole 55 (which can first pass through the locking member 80 and then through the connecting hole 55) and enter the second storage chamber 73. When the depressurization is completed and a new equilibrium is reached, the aerosol generating matrix stored in the second storage chamber 73 will be drawn back to the first storage chamber 71 through the connecting hole 55 under the condition of alternating air pressure changes, or it will be drawn back to the first storage chamber 71 during the atomization process due to the air pressure change in the first storage chamber 71. This can effectively prevent the aerosol generating matrix from depressurizing by entering the air intake channel 15 of the atomizing seat 10, which would cause the air intake channel 15 to become blocked, thus ensuring a good vaping experience for the user.
[0073] Please see Figure 3 In some embodiments, the connecting hole 55 is a notch formed on the outer side wall of the first sub-part 57. Figure 3 Taking the cylindrical structure of the sidewall of the first sub-part 57 as an example, the outer contour of the sidewall of the first sub-part 57 is an open circle, and the open part corresponds to the notch. With this design of the connecting hole 55, on the one hand, the thickness of the sidewall of the first sub-part 57 can be designed to be smaller, and on the other hand, the notch is also easy to process, as long as the notch connects the first storage cavity 71 and the second storage cavity 73.
[0074] In other embodiments, the connecting hole 55 is at least partially located inside the sidewall of the first sub-part 57, with one end of the connecting hole 55 communicating with the first storage cavity 71 and the other end communicating with the second storage cavity 73. In other words, the connecting hole 55 is located inside the sidewall of the first sub-part 57, not as... Figure 3 The notch shown is mostly exposed, with only the two ends exposed, for the aerosol generation matrix to flow into and out of the connecting hole 55.
[0075] Please see Figure 3 In some embodiments, the connecting hole 55 is a straight through hole. A straight through hole can reduce the flow path of the aerosol generating matrix within the connecting hole 55, resulting in faster depressurization and reabsorption speeds.
[0076] In some embodiments, the connecting hole 55 is a curved through hole, meaning it has multiple bends, i.e., the flow direction of the aerosol generating matrix changes within the connecting hole 55. The number of bends can be one (in which case the connecting hole 55 comprises two segments), two (in which case the connecting hole 55 comprises three segments), three (in which case the connecting hole 55 comprises four segments), or more. The curved through hole increases the flow path of the aerosol generating matrix within the connecting hole 55, and the depressurization rate and recirculation rate can be adjusted by setting an appropriate number of segments.
[0077] In the plane along the length direction L of the vertical atomizer 100, the shape of the projection of the connecting hole 55 can be, but is not limited to, a semicircle, a circle, an ellipse, a triangle, a quadrilateral, or other polygons.
[0078] In the plane along the length L of the vertical atomizer 100, the minimum size of the projection of the connecting hole 55 is greater than or equal to 1.0 mm and less than or equal to 2.0 mm. Specifically, the minimum size of the connecting hole 55 can be 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm, etc. The minimum size of the connecting hole 55 being greater than or equal to 1.0 mm and less than or equal to 2.0 mm ensures that when the first storage chamber 71 is subjected to diurnal temperature variations, the aerosol generation matrix in the first storage chamber 71 preferentially leaks out through the connecting hole 55 into the second storage chamber 73, while also ensuring that the sidewall thickness of the first sub-part 57 is appropriate, thus saving costs.
[0079] Please refer to the following: Figure 2 , Figure 4 , Figure 5 and Figure 8 ,or Figure 6 , Figure 7 and Figure 9 In some embodiments, the heating element 60 has a cylindrical structure, and the locking member 80 is arranged around the heating element 60. In this embodiment, the heating element 60 has a cylindrical structure with an atomizing chamber 65 inside, including an end face 63 near the atomizing base 10 and a liquid inlet surface 61. The atomizing chamber 65 is connected to the through hole 21 of the nozzle 20 through the cavity 51. In one example, if the end face of the heating element 60 near the nozzle 20 abuts against the stepped surface of the cavity 51, the atomizing chamber 65 is connected to the through hole 21 of the nozzle 20 through the second sub-cavity 591; in another example, if the end face of the heating element 60 near the nozzle 20 does not abut against the stepped surface of the cavity 51, but is spaced apart, the atomizing chamber 65 is connected to the through hole 21 of the nozzle 20 through the first sub-cavity 571 and the second sub-cavity 591. In addition, the atomizing chamber 65 is also connected to the air inlet channel 15 of the atomizing base 10. The liquid inlet surface 61 is the outer circumferential surface of a cylindrical structure.
[0080] In other embodiments, the heating element 60 has a flat plate structure, and the locking member 80 is opposite to the liquid inlet surface of the heating element 60. In this case, the heating element 60 also includes an atomizing surface opposite to the liquid inlet surface, and the heating element 60 and the side wall of the air guide member 50 form an atomizing cavity, with the atomizing surface located inside the atomizing cavity.
[0081] Whether it is a cylindrical or flat heating element, when the aerosol generating device 1000 is normally drawn in, the outside gas enters the atomizing chamber 65 through the air inlet channel 15 of the atomizing seat 10. The aerosol generating matrix in the first storage chamber 71 first passes through the locking member 80. The aerosol generating matrix in the locking member 80 is then guided towards the heating element 60 through the micropores in the locking member 80. Finally, it enters the interior of the heating element 60 through the liquid inlet surface 61. It then combines with the air entering the atomizing chamber 65 from the air inlet channel 15 and is heated by the heating element 60 to form an aerosol. The formed aerosol enters the atomizing chamber 65 and is drawn into the user's mouth through the cavity 51 and the through hole 21 of the nozzle 20.
[0082] Further, please refer to Figure 2 , Figure 5 , Figure 7 , Figure 8 or Figure 9 In some embodiments, the atomizer 100 further includes a first sealing member 91, which is disposed between the end face 63 of the atomizing base 10 and the heating element 60 near the end of the atomizing base 10. The first sealing member 91 has a through hole 911 penetrating both ends. The mouthpiece 20 has a through hole 21, the heating element 60 has an atomizing chamber 65, and the atomizing base 10 has an air intake channel 15 communicating with the outside. Along the length L of the atomizer 100, the through hole 21, the partial cavity 51, the atomizing chamber 65, the through hole 911, and the air intake channel 15 are sequentially connected and together form a suction channel. The air intake channel 15 communicates with the second storage chamber 73 and together with the second storage chamber 73, the through hole 55, and the first storage chamber 71, forms an air exchange channel.
[0083] The first sealing element 91 can be made of materials such as rubber, silicone, plastic, or synthetic fibers. Rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. When the first sealing element 91 is made of rubber or silicone, the contact between the first sealing element 91 and the heating element 60 and the atomizing seat 10 is tighter, thereby improving the sealing effect of the first sealing element 91 on the gap between the heating element 60 and the atomizing seat 10. The first sealing element 91 is designed to prevent side leakage of the aerosol generation matrix.
[0084] When the aerosol generating device 1000 is being normally drawn in, external gas enters the atomizing chamber 65 through the air inlet channel 15 of the atomizing seat 10. The aerosol generating matrix in the first storage chamber 71 first passes through the locking member 80. The aerosol generating matrix in the locking member 80 is then guided towards the heating element 60 through the micropores in the locking member 80, and finally enters the interior of the heating element 60 through the liquid inlet surface 61. It then combines with the air entering the atomizing chamber 65 from the air inlet channel 15 and is heated by the heating element 60 to form an aerosol. The formed aerosol enters the atomizing chamber 65 and is drawn into the user's mouth through the suction channel (e.g., Figure 8 (As shown by the solid arrow). When the aerosol generating matrix stored in the second storage chamber 73 is drawn back to the first storage chamber 71 through the connecting hole 55 under alternating air pressure conditions, or is drawn back to the first storage chamber 71 during atomization due to air pressure changes, external gas is used for back absorption through the ventilation channel (e.g., Figure 9 (As shown by the dashed arrow).
[0085] Furthermore, please refer to Figure 2 , Figure 5 and Figure 7 In some embodiments, the atomizer 100 may further include a second seal 93, which is disposed between the air guide 50 and the mouthpiece 20 to seal the gap between the air guide 50 and the mouthpiece 20, thereby preventing aerosol in the suction channel from leaking into the first storage chamber 71 through the gap between the air guide 50 and the mouthpiece 20.
[0086] The second seal 93 can be made of materials such as rubber, silicone, plastic, or synthetic fibers. Rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. When the second seal 93 is made of rubber, the contact between the second seal 93 and the nozzle 20 and the air guide 50 is tighter, thereby improving the sealing effect of the second seal 93 on the gap between the nozzle 20 and the air guide 50.
[0087] Please see Figure 10 The aerosol generating device 1000 of the present application includes a battery assembly 300 and an atomizer 100 of any of the above embodiments. The atomizer 100 also includes an electrical connector 95, which electrically connects the heating element 60 and the battery assembly 300.
[0088] The battery assembly 300 supplies power to the heating element 60 in the atomizer 100, thereby enabling the heating element 60 to generate heat to heat the aerosol generation matrix. The atomizer base 10 of this application is provided with threads, and the battery assembly 300 and the atomizer 100 are detachably connected by the threads.
[0089] Please combine Figure 2 , Figure 5 , Figure 7 , Figure 8 or Figure 9 The electrical connector 95 is used to electrically connect the battery assembly 300 and the heating element 60, thereby establishing electrical conductivity between the heating element 60 and the battery assembly 300. When the user inhales, the battery assembly 300 provides electrical energy to the heating element 60, causing the heating element 60 to generate heat. The aerosol generation matrix absorbs the heat to produce an aerosol. The electrical connector 95 can be, but is not limited to, a ring electrode, a flexible pin, or a wire. Preferably, the atomizer 100 also includes a fixing member 97 disposed on the atomizer base 10. The fixing member 97 is used to install and fix the electrical connector 95, ensuring that the electrical connector 95 is securely mounted on the atomizer base 10, thereby enabling stable electrical conductivity between the heating element 60 and the battery assembly 300.
[0090] In the aerosol generating device 1000 of this application embodiment, the locking member 80 has the characteristic of locking the aerosol generating matrix. Its liquid-locking effect can be used to avoid the leakage and blockage problem in the cavity 51 caused by pressure changes due to temperature rise in the oil tank (in the first storage chamber 71), as described in the background. Simultaneously, the two ends of the connecting hole 55 are respectively connected to the first storage chamber 71 and the second storage chamber 73. When the first storage chamber 71 is subjected to day-night temperature differences, the aerosol generating matrix inside will depressurize primarily by leaking out through the connecting hole 55 into the second storage chamber 73. When depressurization is complete and a new equilibrium is reached, the aerosol generating matrix stored in the second storage chamber 73 will be drawn back into the first storage chamber 71 through the connecting hole 55 under alternating air pressure conditions, or drawn back into the first storage chamber 71 during atomization due to air pressure changes. This effectively prevents the aerosol generating matrix from depressurizing by entering the air intake channel 15, thus avoiding blockage of the air intake channel 15 and ensuring a good suction experience for the user.

However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.
