[0005] To achieve the above objectives, the first aspect of this application provides an atomizer, comprising:

[0006] A housing assembly, wherein an air outlet channel and a liquid storage chamber are formed inside the housing assembly, and the liquid storage chamber is used to store the aerosol generation matrix;

[0007] An atomizing assembly, comprising an atomizing base and an atomizing core, wherein at least a portion of the atomizing base is disposed within the housing assembly, and the atomizing core is disposed within the atomizing base; the atomizing base forms an atomizing chamber and a liquid inlet channel, and the atomizing chamber communicates with the air outlet channel;

[0008] The liquid inlet channel includes a first liquid inlet section, a liquid locking port, and a second liquid inlet section. The first liquid inlet section and the second liquid inlet section are connected through the liquid locking port. The first liquid inlet section is connected to the liquid storage chamber, and the second liquid inlet section is connected to the liquid of the atomizing core.

[0009] Wherein, the flow cross-sectional area of ​​the liquid-locking port is smaller than the flow cross-sectional area of ​​at least a portion of the first liquid inlet section.

[0010] In one embodiment, the distance between any two points of the liquid-locking port in the circumferential direction is no greater than 3 mm.

[0011] In one embodiment, the cross-sectional area of ​​the liquid lock port is smaller than the cross-sectional area of ​​other areas of the liquid inlet channel excluding the liquid lock port.

[0012] In one embodiment, the first liquid inlet section includes a constant diameter section and a contraction section, with the end of the contraction section away from the constant diameter section forming the liquid-locking port.

[0013] In one embodiment, the sidewall of the liquid inlet channel is provided with a first capillary groove, which is connected to the second liquid inlet section.

[0014] In one embodiment, the atomizing seat includes an atomizing top seat and an atomizing base, the atomizing top seat being located on the top side of the atomizing base; the atomizing top seat is provided with a first liquid inlet section, the atomizing base is provided with a second liquid inlet section, and the liquid locking port is located at the end of the first liquid inlet section near the second liquid inlet section.

[0015] In one embodiment, a guide column is provided protruding from the bottom wall of the second liquid inlet section, and the guide column extends toward the liquid absorption surface of the atomizing core.

[0016] In one embodiment, the distance between the guide column and the liquid absorption surface of the atomizing core is no greater than 0.15 mm.

[0017] In one embodiment, the number of the guide columns is multiple, and the spacing between each guide column ranges from 0.6 mm to 0.8 mm.

[0018] In one embodiment, the height of the guide column is no greater than 1.1 mm.

[0019] In one embodiment, a second capillary groove is provided on the bottom wall of the second liquid inlet section.

[0020] In one embodiment, the width of the second capillary groove is no greater than 0.6 mm, and the depth of the second capillary groove is no greater than 0.6 mm.

[0021] In one embodiment, the width of the first capillary groove is no greater than 0.6 mm, and the depth of the first capillary groove is no greater than 0.6 mm.

[0022] A second aspect of this application provides an aerosol generating device, the aerosol generating device including a power supply component and an atomizer as described in any of the above embodiments, wherein the power supply component is electrically connected to the atomizer.

The atomizing core can atomize the aerosol generating matrix to form an aerosol. The first liquid inlet section and the second liquid inlet section are connected by a liquid-locking port, the cross-sectional area of ​​which is smaller than at least part of the flow cross-sectional area of ​​the first liquid inlet section. Thus, bubbles formed by the aerosol generating matrix during flow can accumulate at the liquid-locking port, forming an airlock to prevent the aerosol generating matrix in the second liquid inlet section from flowing into the first liquid inlet section. In addition, a liquid film easily forms at the liquid-locking port, further blocking the aerosol generating matrix in the second liquid inlet section. The blocking effect of the liquid-locking port on the aerosol generation matrix in the second liquid inlet section helps to lock in a certain amount of aerosol generation matrix in the "inverted state" or "tilted state", so as to supply liquid to the atomizing core, thereby solving the problem of dry burning of the atomizing core in the above states and improving the user experience.

For example, the aerosol generating device may be a medical nebulizer, an air humidifier, or an electronic cigarette, or other device that requires the use of a nebulizer.

[0041] This application provides an atomizer 1000; please refer to [link / reference]. Figures 1 to 3The atomizer 1000 includes a housing assembly 200 and an atomizing assembly 100. The housing assembly 200 has an air outlet channel 201 and a liquid storage chamber 202 inside, the liquid storage chamber 202 being used to store the aerosol generation matrix. The atomizing assembly 100 includes an atomizing base 1 and an atomizing core 2, at least a portion of the atomizing base 1 being disposed within the housing assembly 200, and the atomizing core 2 being disposed within the atomizing base 1. The atomizing base 1 has an atomizing chamber 11 and a liquid inlet channel 12, the atomizing chamber 11 being connected to the air outlet channel 201. The liquid inlet channel 12 includes a first liquid inlet section 121, a liquid-locking port 123, and a second liquid inlet section 122, the first liquid inlet section 121 and the second liquid inlet section 122 being connected through the liquid-locking port 123, the first liquid inlet section 121 being connected to the liquid storage chamber 202, and the second liquid inlet section 122 being in liquid communication with the atomizing core 2. The flow cross-sectional area of ​​the liquid lock port 123 is smaller than the flow cross-sectional area of ​​at least part of the first liquid inlet section 121.

[0042] The housing assembly 200 may have a liquid storage chamber 202 inside, which may be defined by the housing assembly 200 or by the housing assembly 200 and the atomizing seat 1.

[0043] The housing assembly 200 is the outer housing of the atomizer 1000, and an air outlet channel 201 is formed inside it. At least a portion of the atomizing base 1 is disposed within the housing assembly 200.

[0044] The air outlet passage 201 can be located in the middle area within the housing assembly 200, or it can be located on the side of the middle area of ​​the housing assembly 200.

[0045] In some embodiments, the top of the atomizing seat 1 and the inner sidewall of the housing assembly 200 define a liquid storage chamber 202 for storing the aerosol generation matrix, and the liquid storage chamber 202 is arranged around the gas outlet channel 201.

[0046] In other embodiments, a liquid storage cavity 202 may be formed inside the housing assembly 200.

[0047] The atomizing component 100 refers to the structure in the atomizer 1000 that has the atomizing function, and the aerosol generating matrix generates aerosols within the atomizing component 100.

[0048] For example, the fact that at least a portion of the atomizer base 1 is disposed within the housing assembly 200 can mean that a portion of the structure of the atomizer base 1 is disposed within the housing assembly 200, or it can mean that the entire structure of the atomizer base 1 is disposed within the housing assembly 200.

[0049] For example, the atomizing base 1 has an air intake channel that connects the outside world and the atomizing chamber 11.

[0050] For example, the atomizing base 1 has an atomizing chamber 11 and a liquid inlet channel 12. The liquid inlet channel 12 connects the liquid storage chamber 202 and the atomizing chamber 11, and the atomizing chamber 11 is connected to the air outlet channel 201. The aerosol generating matrix in the liquid storage chamber 202 enters the atomizing core 2 through the liquid inlet channel 12 for atomization. The aerosol formed after atomization flows through the air outlet channel 201 along with the air flowing in through the air inlet channel and is discharged to the outside through the air outlet for user use.

[0051] The atomizing core 2 is used to absorb the aerosol generation matrix and atomize the aerosol generation matrix to form an aerosol.

[0052] For example, the atomizing core 2 has a through-hole microporous structure. The side of the atomizing core 2 that connects the microporous structure to the liquid storage chamber 202 is the liquid absorption surface, and the side of the atomizing core 2 that connects the microporous structure to the atomizing chamber 11 is the atomizing surface.

[0053] In some embodiments, the atomizing core 2 has an atomizing structure on the atomizing surface. The specific atomizing structure is not limited here, but can be a heating wire, etc.

[0054] The atomizing base 1 is the main site where the aerosol generating matrix is ​​transformed into aerosol. It is usually made of a sturdy material to ensure stability during the atomization process. The atomizing base 1 provides support for the atomizing core 2 and forms the atomization chamber 11, in which the aerosol generating matrix is ​​transformed into aerosol.

[0055] The specific structure of the atomizer base 1 is not limited here. For example, it can be a one-piece molded structure or it can be assembled from multiple parts.

[0056] The atomizing chamber 11 is a space within the atomizing base 1, connected to the air outlet channel 201, and is where the aerosol generating matrix is ​​atomized into fine particles. During the atomization process, the atomizing chamber 11 provides the necessary space so that the aerosol generating matrix can be dispersed into tiny aerosol particles through the atomizing core 2.

[0057] The specific structure of the atomizing chamber 11 is determined based on the actual situation and is not limited here.

[0058] The liquid inlet channel 12 is a channel connecting the liquid storage chamber 202 and the atomizing core 2. The liquid inlet channel 12 transports the aerosol generation matrix from the liquid storage chamber 202 to the atomizing core 2.

[0059] The first liquid inlet section 121 is the starting part of the liquid inlet channel 12, and it is directly connected to the liquid storage chamber 202. As a channel for liquid inflow, the first liquid inlet section 121 guides the aerosol generation matrix to be smoothly transferred from the liquid storage chamber 202 to the subsequent atomization process.

[0060] The second liquid inlet section 122 is the end portion of the liquid inlet channel 12 and is directly connected to the liquid inlet of the atomizing core 2. During atomization, the second liquid inlet section 122 guides the aerosol generation matrix to be continuously and stably supplied to the atomizing core 2, thereby generating aerosol.

[0061] The liquid lock port 123 is the intermediate part connecting the first liquid inlet section 121 and the second liquid inlet section 122, and is used to control the liquid flow direction. The flow cross-sectional area of ​​the liquid lock port 123 is smaller than the flow cross-sectional area of ​​at least part of the first liquid inlet section 121, and this area difference can limit the flow. When the aerosol generating matrix in the liquid storage chamber 202 flows through the liquid lock port 123 with a smaller flow cross-sectional area, the flow velocity of the liquid is limited.

[0062] In the "inverted state" or "tilted state", the liquid lock port 123 can prevent the aerosol generation matrix in the second liquid inlet section 122 from flowing into the first liquid inlet section 121.

[0063] "Inverted state" means that in this state, the liquid storage chamber 202 is located below the atomizing component 100, and the aerosol generation matrix in the liquid storage chamber 202 cannot enter the atomizing core 2 of the atomizing component 100 under the action of gravity or other forces.

[0064] "Tilted state" refers to a state in which the liquid storage chamber 202 is positioned above the atomizing assembly 100, and the angle between the central axis of the atomizer 1000 and the horizontal plane is between 0° and 180°, or the angle between the central axis of the atomizer 1000 and the horizontal plane is 0° or 180°.

[0065] When the atomizer 1000 is in an "inverted" or "tilted" state, the design of the liquid-locking port 123 allows bubbles to converge there, forming an airlock that prevents the aerosol generation matrix in the second liquid inlet section 122 from flowing back or leaking. More specifically, when the atomizer 1000 is inverted, bubbles rise and move towards the liquid-locking port 123 due to gravity. Since the cross-sectional area of ​​the liquid-locking port 123 is smaller than at least a portion of the cross-sectional area of ​​the first liquid inlet section 121, bubbles can converge at the liquid-locking port 123, forming an airlock that prevents the aerosol generation matrix in the second liquid inlet section 122 from flowing into the first liquid inlet section 121.

[0066] In addition, due to the small cross-sectional area of ​​the liquid-locking port 123, the aerosol generating matrix can easily form a liquid film under the liquid-locking port 123 due to the liquid tension. The liquid film can also block the aerosol generating matrix in the second liquid inlet section 122.

[0067] The specific structure of the liquid-locking port 123 is not limited here; any structure with the above functions is acceptable.

[0068] It should be noted that the flow cross-sectional area of ​​the liquid lock port 123 is less than at least part of the flow cross-sectional area of ​​the first liquid inlet section 121. This can be either the flow cross-sectional area of ​​the liquid lock port 123 being only less than the minimum flow cross-sectional area of ​​the first liquid inlet section 121, or the flow cross-sectional area of ​​the liquid lock port 123 being less than the maximum flow cross-sectional area of ​​the first liquid inlet section 121.

[0069] In some embodiments, the flow cross-sectional area of ​​the liquid-locking port 123 is smaller than the minimum flow cross-sectional area of ​​the first liquid inlet section 121. Meanwhile, near the second liquid inlet section 122, the flow cross-sectional area of ​​the liquid-locking port 123 may be smaller than the minimum flow cross-sectional area of ​​the second liquid inlet section 122, or the flow cross-sectional area of ​​the liquid-locking port 123 may be smaller than the maximum flow cross-sectional area of ​​the second liquid inlet section 122, or the flow cross-sectional area of ​​the liquid-locking port 123 may be equal to the flow cross-sectional area of ​​the second liquid inlet section 122.

[0070] In some embodiments, the flow cross-sectional area of ​​the liquid-locking port 123 is smaller than the maximum flow cross-sectional area of ​​the first liquid inlet section 121. Meanwhile, near the second liquid inlet section 122, the cross-sectional area of ​​the liquid-locking port 123 may be smaller than the minimum flow cross-sectional area of ​​the second liquid inlet section 122, or the cross-sectional area of ​​the liquid-locking port 123 may be smaller than the maximum flow cross-sectional area of ​​the second liquid inlet section 122, or the flow cross-sectional area of ​​the liquid-locking port 123 may be equal to the flow cross-sectional area of ​​the second liquid inlet section 122.

[0071] The flow cross-sectional area refers to the cross-sectional area perpendicular to the main flow direction along the fluid flow path, through which the fluid flows from one side to the other.

[0072] Taking the first liquid inlet section 121 as an example, the flow cross-sectional area of ​​the first liquid inlet section 121 refers to the area of ​​the cross section on the first liquid inlet section 121 that is perpendicular to the flow direction of the aerosol generating matrix when the aerosol generating matrix flows in the first liquid inlet section 121.

[0073] The atomizer 1000 provided in this application embodiment, by providing a first liquid inlet section 121 and a second liquid inlet section 122 connected within the liquid inlet channel 12, with the first liquid inlet section 121 connected to the liquid storage chamber 202 and the second liquid inlet section 122 in liquid communication with the atomizing core 2, can deliver the aerosol generating matrix in the liquid storage chamber 202 to the atomizing core 2. The atomizing core 2 can atomize the aerosol generating matrix to form an aerosol. The first liquid inlet section 121 and the second liquid inlet are connected by a liquid-locking port 123. The cross-sectional area of ​​the liquid-locking port 123 is smaller than at least a portion of the flow cross-sectional area of ​​the first liquid inlet section 121. Thus, bubbles formed by the aerosol generating matrix during flow can accumulate at the liquid-locking port 123, forming an airlock to prevent the aerosol generating matrix in the second liquid inlet section 122 from flowing into the first liquid inlet section 121. In addition, a liquid film can easily form at the liquid-locking port 123, further blocking the aerosol generating matrix in the second liquid inlet section 122. The blocking effect of the liquid-locking port 123 on the aerosol generation matrix in the second liquid inlet section 122 is beneficial to lock in a certain amount of aerosol generation matrix in the "inverted state" or "tilted state" to supply liquid to the atomizing core 2, thereby solving the problem of dry burning of the atomizing core 2 in the above state and improving the user experience.

[0074] In some embodiments, please refer to Figures 1 to 2 The distance between any two points of the liquid-locking port 123 in the circumferential direction shall not exceed 3mm.

[0075] The distance between any two points of the liquid-locking port 123 in the circumferential direction is no more than 3mm, for example, it can be 0.3mm, 0.6mm, 0.9mm, 1.2mm, 1.5mm, 1.8mm, 2.1mm, 2.4mm, 2.7mm, 3mm, etc.

[0076] The distance between any two points not exceeding 3mm means that the maximum size measured within the range defined by the liquid-locking port 123 is less than or equal to 3mm. Within this range, it can be ensured that the air bubbles of the liquid-locking port 123 can effectively lock the aerosol generation matrix in the second liquid inlet section, which is beneficial to improving the liquid-locking effect of the aerosol generation matrix in the second liquid inlet section under the inverted state.

[0077] It should be noted that the larger the size of the liquid-locking port 123, the larger the flow cross-sectional area, and the smaller the flow resistance of the aerosol generating matrix between the first liquid inlet section and the second liquid inlet 122. However, at the same time, the liquid-locking effect of the liquid-locking port 123 in the inverted state is correspondingly weakened. The specific size and structure of the liquid-locking port 123 are determined within the above-mentioned size range according to actual needs.

[0078] Controlling the size of the liquid-locking port 123 within the above-mentioned range is beneficial to controlling the liquid-locking effect of the liquid-locking port 123, and also beneficial to controlling the flow rate of the aerosol generation matrix between the first liquid inlet section and the second liquid inlet 122.

[0079] In some embodiments, please refer to Figures 1 to 2 The cross-sectional area of ​​the liquid lock port 123 is smaller than the cross-sectional area of ​​the other areas of the liquid inlet channel except for the liquid lock port 123.

[0080] By changing the dynamic characteristics of liquid flow to control the flow of liquid, when the cross-sectional area of ​​the liquid lock port 123 is smaller than the cross-sectional area of ​​other areas of the liquid inlet channel except for the liquid lock port 123, it helps the bubbles to flow towards the liquid lock port 123 due to buoyancy when the atomizer 1000 is inverted, and to gather at the liquid lock port 123 to form an airlock, preventing the aerosol generation matrix in the second liquid inlet section from flowing back, thereby locking the aerosol generation matrix.

[0081] In some embodiments, please refer to Figures 1 to 3 The first liquid inlet section includes a constant diameter section 1211 and a contraction section 1212. The end of the contraction section 1212 away from the constant diameter section 1211 forms a liquid-locking port 123.

[0082] The constant diameter section 1211 refers to the pipe section within the first liquid inlet section that has a constant inner diameter. The diameter of the pipe remains unchanged along the entire length of the constant diameter section 1211. The constant diameter section 1211 can provide a stable fluid flow environment, allowing the aerosol generation matrix to flow smoothly from the liquid storage chamber to the subsequent pipe sections.

[0083] The contraction section 1212 refers to the portion within the first liquid inlet section where the inner diameter gradually decreases. The contraction section 1212 is used to gradually reduce the size of the first liquid inlet section. On one hand, the design of the contraction section 1212 can guide the aerosol-generating matrix of the first liquid inlet section to converge towards the liquid-locking port 123 and flow towards the second liquid inlet section, which helps reduce the residual aerosol-generating matrix in the storage chamber. On the other hand, the design of the constant-diameter section 1211 also facilitates the formation of the liquid-locking port 123.

[0084] It is understandable that, since the distance between any two points of the liquid-locking port 123 in the circumferential direction is no more than 3 mm, the size of the contraction section 1212 also approaches the range of less than 3 mm along the direction away from the equal diameter section 1211.

[0085] The design of forming a liquid-locking port 123 by transitioning from the equal diameter section 1211 to the contraction section 1212 in the first liquid inlet section can utilize the principle of bubble dynamics. In the inverted state, bubbles will rise and gather at the liquid-locking port 123 to form an airlock, preventing the aerosol matrix generated in the second liquid inlet section from flowing back.

[0086] In some embodiments, please refer to Figures 1 to 3 The side wall of the liquid inlet channel is provided with a first capillary groove, which is connected to the second liquid inlet section.

[0087] The first capillary groove is a small channel provided on the side wall of the liquid inlet channel, and the first capillary groove is connected to the second liquid inlet section. For example, the first capillary groove may be provided on the side wall of the first liquid inlet section, or the first capillary groove may be provided on the side walls of both the first liquid inlet section and the second liquid inlet section.

[0088] The capillary channel utilizes capillary action to help control the flow of liquid. When inverted, the first capillary channel uses capillary action to assist the liquid-locking port 123 in locking the aerosol generation matrix locked in the second liquid inlet section.

[0089] Furthermore, the first capillary groove connects the first liquid inlet section and the second liquid inlet section. In the inverted state, when the aerosol generating matrix in the first liquid inlet section comes into contact with the first capillary groove, the first capillary groove can also attract the aerosol generating matrix in the first liquid inlet section through capillary action and flow it to the second liquid inlet section to replenish the aerosol generating matrix continuously consumed by the atomizing core in the second liquid inlet section. This achieves a continuous supply of aerosol generating matrix required for atomization of the atomizing core in the inverted state.

[0090] The specific structure and shape of the first capillary groove are not limited here. The ability of the first capillary groove to control the liquid can be optimized by changing the size, shape or surface characteristics of the capillary groove.

[0091] For example, wettability is increased by increasing the surface area of ​​the first capillary groove, thereby improving the efficiency of liquid transport.

[0092] For example, the sidewall of the first capillary groove is a serrated structure formed by bending, which increases the surface area of ​​the first capillary groove.

[0093] By setting a first capillary groove, when in the inverted state, the first capillary groove uses capillary action to assist the liquid-locking port 123 in locking the aerosol generating matrix stored in the second liquid inlet section. When the aerosol generating matrix in the first liquid inlet section comes into contact with the first capillary groove, the first capillary groove can also attract the aerosol generating matrix in the first liquid inlet section through capillary action and flow it to the second liquid inlet section to replenish the aerosol generating matrix continuously consumed by the atomizing core in the second liquid inlet section. This achieves a continuous supply of aerosol generating matrix required for atomization of the atomizing core even in the inverted state, with a simple and effective structure.

[0094] In some embodiments, please refer to Figures 1 to 3 The atomizing base 1 includes an atomizing top seat and an atomizing base. The atomizing top seat is located on the top side of the atomizing base. The atomizing top seat is provided with a first liquid inlet section, and the atomizing base is provided with a second liquid inlet section. The liquid locking port 123 is located at the end of the first liquid inlet section near the second liquid inlet section.

[0095] The atomizing top seat is located at the top of the atomizing base and is part of the atomizing base 1. The atomizing top seat is provided with a first liquid inlet section. The atomizing top seat is used to guide the aerosol generation matrix in the liquid storage chamber to the atomizing core.

[0096] The nebulizer base is located below the nebulizer seat 1, and the nebulizer base is provided with a second liquid inlet section. The nebulizer base is used to guide the liquid medicine in the first liquid inlet section to the nebulizer core.

[0097] The specific structure of the atomizing top and atomizing base is not limited here, as long as it is convenient to form the first liquid inlet section, the liquid locking port 123 and the second liquid inlet section.

[0098] For example, both the atomizing top seat and the atomizing base are integrally molded structures, such as by injection molding. The atomizing top seat and the atomizing base can be directly formed into the first liquid inlet section and the second liquid inlet section during the molding process through the mold, without the need for additional processing to form the first liquid inlet section and the second liquid inlet section, which is beneficial to improving production efficiency.

[0099] For example, the connection between the atomizing top seat and the atomizing base is sealed with a sealing structure, such as sealing silicone. This improves the sealing performance between the first liquid inlet section and the second liquid inlet section, ensuring that the air bubbles collected at the liquid-locking port 123 are not affected by external factors, and ensuring the liquid-locking effect of the liquid-locking port 123.

[0100] Atomizing base 1 is composed of an atomizing top seat and an atomizing base. The atomizing top seat is provided with a first liquid inlet section, and the atomizing base is provided with a second liquid inlet section. The complex atomizing base structure is broken down into two easily moldable parts, which reduces the difficulty of the production process of atomizing base 1, and helps to improve the yield rate and production efficiency of atomizing base 1.

[0101] In some embodiments, please refer to Figures 1 to 3 The bottom wall of the second liquid inlet section has a protruding guide column that extends toward the liquid absorption surface of the atomizing core.

[0102] The guide column is a structure that protrudes from the bottom wall of the second liquid inlet section and extends towards the liquid absorption surface of the atomizing core. The guide column is used to more effectively guide the aerosol generating matrix in the second liquid inlet section towards the atomizing core, reduce the residue of the aerosol generating matrix in the second liquid inlet section, and improve atomization efficiency.

[0103] The specific structure of the guide column is not limited here. By changing the shape and angle of the guide column, the path of the liquid flow to the atomizing core can be further optimized, reducing the resistance and dead zone of the liquid flow and improving the atomization efficiency.

[0104] In some embodiments, multi-stage guide columns or guide channels can be designed to increase the surface area of ​​contact between the liquid and the atomizing core, thereby promoting a more uniform atomization effect.

[0105] For example, the guide column is frustum-shaped, which facilitates demolding of the guide column during the mold forming process.

[0106] By setting a guide column protruding from the bottom wall of the second liquid inlet section, it is beneficial to guide the aerosol generation matrix in the second liquid inlet section to the atomizing core more effectively, reduce the residue of the aerosol generation matrix in the second liquid inlet section, and improve atomization efficiency.

[0107] In some embodiments, please refer to Figures 1 to 3 The distance between the guide column and the liquid absorption surface of the atomizing core should not exceed 0.15mm.

[0108] The distance between the guide column and the liquid absorption surface of the atomizing core is no more than 0.15mm, for example, it can be 0.02mm, 0.04mm, 0.06mm, 0.08mm, 0.1mm, 0.12mm, 0.14mm, 0.15mm, etc.

[0109] By setting the distance between the guide column and the liquid absorption surface of the atomizing core within this range, the gap formed by this tiny distance can utilize capillary force to attract the aerosol generation matrix on the guide column to the liquid absorption surface of the atomizing core.

[0110] In some embodiments, please refer to Figures 1 to 3 There are multiple guide columns, and the spacing between each guide column ranges from 0.6mm to 0.8mm.

[0111] The spacing between each guide column ranges from 0.6mm to 0.8mm, for example, it can be 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, etc.

[0112] The arrangement of multiple guide columns can improve the guiding effect on the aerosol generation matrix. On the other hand, the spacing between the guide columns is within the aforementioned range, and the gaps between the guide columns can utilize capillary force to lock the aerosol generation matrix in the second liquid inlet section within these gaps. The auxiliary liquid-locking port 123 further assists in locking the aerosol generation matrix in the second liquid inlet section.

[0113] It is understandable that the more flow guide columns there are, the more gaps are formed between them, and the better the flow guide columns' liquid-locking effect on the aerosol generation matrix. The specific number of flow guide columns is not limited here.

[0114] In some embodiments, please refer to Figures 1 to 3 The height of the guide column should not exceed 1.1mm.

[0115] The height of the guide column should not exceed 1.1mm, for example, it can be 0.1mm, 0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.1mm, etc.

[0116] Since capillary action has limited ability to attract liquid, the height of the guide column needs to be controlled within the effective range of capillary action, which is no more than 1.1 mm. In this way, the guide column can guide the aerosol generation matrix in the second liquid inlet section 122 to the liquid absorption surface of the atomizing core through capillary action.

[0117] In some embodiments, please refer to Figures 1 to 3 The bottom wall of the second liquid inlet section is provided with a second capillary groove.

[0118] The second capillary groove is a small channel located on the bottom wall of the second liquid inlet section. The second capillary groove uses capillary action to help control the flow of liquid. When in the inverted state, the second capillary groove uses capillary action to assist the liquid locking port 123 in locking the aerosol generation matrix in the second liquid inlet section.

[0119] The specific structure and shape of the second capillary are not limited here. The ability of the second capillary to control the liquid can be optimized by changing the size, shape or surface characteristics of the capillary.

[0120] For example, wettability is increased by increasing the surface area of ​​the second capillary groove, thereby improving the efficiency of liquid transport.

[0121] For example, the second capillary groove is a groove-shaped structure disposed on the bottom wall of the second liquid inlet section. The curved edge design of the second capillary groove is beneficial to increasing the surface area of ​​the second capillary groove, thereby improving the liquid-locking ability of the second capillary groove.

[0122] For example, the second capillary groove extends to the guide column. In this way, while locking the aerosol generation matrix, the second capillary groove can also guide the aerosol generation matrix remaining at the bottom of the second liquid inlet section to the guide column, and then to the atomizing core, thereby improving the liquid transfer efficiency.

[0123] By providing a second capillary groove on the bottom wall of the second inlet section, when inverted, the second capillary groove utilizes capillary action to assist the locking port 123 in locking the aerosol generation matrix within the second inlet section. Furthermore, the second capillary groove can also guide the aerosol generation matrix within the second inlet section to flow through the guide column, improving liquid transfer efficiency.

[0124] In some embodiments, please refer to Figures 1 to 3 The width of the second capillary groove is no greater than 0.6 mm, and the depth of the second capillary groove is no greater than 0.6 mm.

[0125] The width of the second capillary groove is no greater than 0.6 mm, for example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, etc.

[0126] The depth of the second capillary groove is no greater than 0.6 mm, for example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, etc.

[0127] The width here refers to the distance between the opposing surfaces that make up the second capillary groove.

[0128] The depth here refers to the distance from the opening plane that forms the second capillary groove to the bottom of the second capillary groove.

[0129] It should be noted that the length of the second capillary groove is not limited here.

[0130] By limiting the width and depth of the second capillary groove within the aforementioned range, the effect of capillary force in the second capillary groove can be guaranteed, and the liquid-locking capacity of the second capillary groove can be improved.

[0131] In some embodiments, please refer to Figures 1 to 3 The width of the first capillary groove is no greater than 0.6 mm, and the depth of the first capillary groove is no greater than 0.6 mm.

[0132] The width of the first capillary groove is no greater than 0.6 mm, for example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, etc.

[0133] The depth of the first capillary groove is no greater than 0.6 mm, for example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, etc.

[0134] The width here refers to the distance between the opposing surfaces that make up the first capillary groove.

[0135] The depth here refers to the distance from the opening plane that forms the first capillary groove to the bottom of the first capillary groove.

[0136] It should be noted here that the length of the first capillary groove is not limited.

[0137] By limiting the width and depth of the first capillary groove within the aforementioned range, the effect of capillary force in the first capillary groove can be guaranteed, and the liquid-locking capacity of the first capillary groove can be improved.
