The aerosol generating matrix includes, but is not limited to, pharmaceuticals, nicotine-containing materials, or nicotine-free materials. In embodiments of this disclosure, the aerosol generating matrix may, for example, be a liquid material made primarily of plants (e.g., tobacco) with added aerosol-forming agents and aroma materials.

[0053] The power supply unit is electrically connected to the atomizer. The power supply unit is mainly used to supply power to the atomizer and control the opening and closing of the entire aerosol generation device.

[0054] Those skilled in the art will understand that the embodiments disclosed herein do not specifically limit the type of aerosol generating device. For example, an aerosol generating device may be a medical nebulizer, an air humidifier, or an electronic cigarette, or any other device that requires the use of a nebulizer.

[0055] This disclosure provides an atomizer 1000. Referring to Figures 1 to 5, the atomizer 1000 includes a housing assembly 300, an atomizing assembly 100, and a ventilation channel 200. The housing assembly 300 has an outlet channel 301 and a liquid storage chamber 302 inside, the liquid storage chamber 302 being used to store an aerosol generation matrix. The atomizing assembly 100 includes an atomizing seat 1 and an atomizing core 2. At least a portion of the atomizing seat 1 is disposed within the housing assembly 300, and the atomizing core 2 is disposed within the atomizing seat 1. The atomizing seat 1 forms an atomizing chamber 11 and a liquid inlet channel 12. The atomizing chamber 11 is in gas communication with the outlet channel 301, the liquid inlet of the liquid inlet channel 12 is connected to the liquid storage chamber 302, and the liquid outlet of the liquid inlet channel 12 is in liquid communication with the atomizing core 2. The outlet 201 of the ventilation channel 200 is connected to the liquid storage chamber 302, and the inlet 202 of the ventilation channel 200 is connected to the atomizing chamber 11. The atomizing base 1 is also provided with a liquid storage structure 13. The air inlet 202 of the air exchange channel 200 is connected to the liquid storage structure 13. The liquid storage structure 13 can be used to store the liquid flowing to the liquid storage structure 13.

[0056] The housing assembly 300 may have a liquid storage chamber 302 inside, which may be defined by the housing assembly 300 or by the housing assembly 300 and the atomizing seat 1.

[0057] The housing assembly 300 is the outer housing of the atomizer 1000, and an air outlet channel 301 is formed inside it. At least a portion of the atomizing base 1 is disposed within the housing assembly 300.

[0058] The air outlet passage 301 can be located in the middle area within the housing assembly 300, or it can be located on the side of the middle area of ​​the housing assembly 300.

[0059] In some embodiments, the top of the atomizing seat 1 and the inner sidewall of the housing assembly 300 define a liquid storage chamber 302 for storing the aerosol generation matrix, and the liquid storage chamber 302 is arranged around the gas outlet channel 301.

[0060] In other embodiments, a liquid storage cavity 302 may be formed inside the housing assembly 300.

[0061] 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.

[0062] For example, the fact that at least a portion of the atomizer base 1 is disposed within the housing assembly 300 can mean that a portion of the structure of the atomizer base 1 is disposed within the housing assembly 300, or it can mean that the entire structure of the atomizer base 1 is disposed within the housing assembly 300.

[0063] For example, the atomizing base 1 has an air intake channel that connects the outside world and the atomizing chamber 11.

[0064] 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 302 and the atomizing core 2. The atomizing chamber 11 is in gas communication with the air outlet channel 301. The aerosol generating matrix in the liquid storage chamber 302 enters the atomizing core 2 through the liquid inlet channel 12 for atomization. The aerosol formed after atomization flows through the air outlet channel 301 along with the air flowing in through the air inlet channel and is discharged to the outside through the air outlet 201 for user use.

[0065] The atomizing core 2 is used to absorb the aerosol generation matrix and atomize the aerosol generation matrix to form an aerosol.

[0066] 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 cavity 302 is the liquid absorption surface, and the side of the atomizing core 2 that connects the microporous structure to the atomizing cavity 11 is the atomizing surface.

[0067] In some embodiments, the atomizing core 2 has an atomizing structure on the atomizing surface. The specific atomizing structure is not limited here, but may be a heating wire, etc.

[0068] 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.

[0069] 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.

[0070] The atomizing chamber 11 is a space within the atomizing base 1, connected to the air outlet channel 301, and is the area 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.

[0071] The specific structure of the atomizing chamber 11 is determined based on the actual situation and is not limited here.

[0072] In some embodiments, a guide rib is provided in the atomizing chamber 11. The guide rib can guide the condensed aerosol generating matrix and the unatomized aerosol generating matrix to the atomizing core 2, so as to make full use of these aerosol generating matrices and improve the utilization efficiency of the aerosol generating matrix.

[0073] The liquid inlet channel 12 is a channel connecting the liquid storage chamber 302 and the atomizing core 2. The atomizing core 2 is in liquid communication with the liquid outlet of the liquid inlet channel 12, so that the aerosol generation matrix can be transported from the liquid storage chamber 302 to the atomizing core 2.

[0074] The ventilation channel 200 serves to circulate air within the atomizer 1000. Its outlet 201 is connected to the liquid storage chamber 302, and its inlet 202 is connected to the atomization chamber 11. The ventilation channel 200 is used to maintain the pressure balance inside the liquid storage chamber 302. The pressure balancing process is as follows:

[0075] When changes in external air pressure or temperature cause the internal air pressure of the storage chamber 302 to exceed the external ambient air pressure, the aerosol-generating matrix or gas within the storage chamber 302 is forced out through the ventilation channel 200 into the storage structure 13, reducing the internal air pressure. This continues until the internal air pressure of the storage chamber 302 equals the external ambient air pressure, at which point the extrusion of the aerosol-generating matrix or gas within the storage chamber 302 ceases. The extruded gas can be discharged to the outside, while the extruded aerosol-generating matrix can be stored in the storage structure 13, improving leakage prevention.

[0076] When changes in external air pressure or temperature cause the internal air pressure of the liquid storage chamber 302 to be lower than the external ambient air pressure, the external gas or the aerosol generation matrix stored in the liquid storage structure 13 is squeezed into the liquid storage chamber 302 until the internal air pressure of the liquid storage chamber 302 equals the external ambient air pressure, at which point the external gas or the aerosol generation matrix stored in the liquid storage structure 13 stops being squeezed in.

[0077] The liquid storage structure 13 is located on the atomizer seat 1 and is used to store the liquid flowing to this structure. During transportation and storage, due to changes in external air pressure or temperature, when the internal air pressure of the atomizer 1000 is lower than the external ambient air pressure, the aerosol generating matrix in the liquid storage chamber 302 may overflow from the ventilation channel 200. By connecting the air inlet 202 of the ventilation channel 200 to the liquid storage structure 13, the overflowing aerosol generating matrix can be guided to the liquid storage structure 13, where it is stored.

[0078] The specific implementation form of the liquid-locking function of the liquid storage structure 13 is not limited here.

[0079] For example, the liquid storage structure 13 is provided with a tortuous and complex liquid guiding channel, which uses the labyrinth effect to lock in the matrix generated by the overflowing aerosol.

[0080] For example, the liquid storage structure 13 is provided with a mechanical locking device, using a small mechanical structure, such as a baffle or valve, to physically prevent the flow of the aerosol generation matrix.

[0081] The atomizer 1000 provided in this embodiment maintains pressure balance within the liquid storage chamber 302 by providing a ventilation channel 200, with its two ends connected to the liquid storage chamber 302 and the atomization chamber 11, respectively. Simultaneously, a liquid storage structure 13 with a liquid-locking function is provided, connecting the air inlet 202 of the ventilation channel 200 to the liquid storage structure 13. Thus, when changes in external air pressure or temperature cause the internal air pressure of the liquid storage chamber 302 to exceed the external ambient air pressure, the aerosol-generating matrix within the liquid storage chamber 302 is forced out through the ventilation channel 200 to the liquid storage structure 13, which stores the aerosol-generating matrix, reducing leakage. When the internal and external air pressures of the atomizer 1000 reach equilibrium, the aerosol-generating matrix on the liquid storage structure 13 flows back into the liquid storage chamber 302 through the ventilation channel 200 for normal use. This solves the leakage problem of the atomizer 1000 while reducing waste of the aerosol-generating matrix and improving the user experience.

[0082] In one embodiment, the lowest point of the air inlet 202 of the ventilation channel 200 is not higher than the lowest point of the liquid storage structure 13.

[0083] Here, the lowest point of the air inlet 202 of the ventilation channel 200 is not higher than the lowest point of the liquid storage structure 13. When the internal and external air pressures of the atomizer 1000 are balanced, the aerosol generation matrix that leaks into the liquid storage structure 13 can, under the action of gravity, collect at the air inlet 202 of the ventilation channel 200 and flow back to the liquid storage chamber 302 through the ventilation channel 200 for use by the atomizing core 2 during atomization. In this way, the residue of the aerosol generation matrix in the liquid storage structure 13 during normal use is reduced, thus reducing the waste of the aerosol generation matrix.

[0084] In some embodiments, please refer to Figures 1 and 2. The liquid storage structure 13 includes a first liquid pocket region 131, which is capable of storing liquid flowing to the first liquid pocket region 131 under the action of capillary force.

[0085] Capillary force refers to the force exerted by a liquid at the interface between a liquid and a solid, due to surface tension, causing the liquid to move along the surface of the solid.

[0086] The first liquid-holding region 131 is the area in the liquid storage structure 13 used to lock in the liquid. This region uses capillary action to store the aerosol generation matrix flowing into the region. The first liquid-holding region 131 is designed to utilize the surface tension between the liquid and solid contact surfaces to maintain the stable storage of the aerosol generation matrix through capillary action, thereby locking in any overflowing aerosol generation matrix.

[0087] The specific structure of the first liquid-collecting region 131 is not limited here. The first liquid-collecting region 131 should have a capillary structure and be able to provide capillary force to store the liquid flowing to the first liquid-collecting region 131.

[0088] For example, the first liquid-collecting region 131 undergoes a special surface treatment, which can enhance capillary force by changing the chemical properties or physical structure of the surface, such as a hydrophilic coating, thereby improving the retention of the aerosol-generating matrix.

[0089] By setting up a first liquid-holding zone 131, the liquid flowing into the first liquid-holding zone 131 is stored by the capillary effect between the structure of the first liquid-holding zone 131 and the liquid. There is no need to set up an additional liquid-locking structure. The structure is simple and easy to set up, which helps to reduce production costs.

[0090] In some embodiments, referring to Figures 1 and 2, the first liquid-collecting region 131 includes a first capillary groove 1311 extending along a first direction. The first capillary groove 1311 penetrates the circumferential sidewall of the atomizing seat 1. The first capillary groove 1311 can store the liquid flowing into the first capillary groove 1311 under the action of capillary force. The air inlet 202 of the ventilation channel 200 is connected to the atomizing chamber 11 through the first liquid-collecting region 131. The first direction intersects with the height direction of the atomizing chamber 11. For ease of explanation, the first direction and the height direction refer to the directions shown in Figures 1 and 2. Of course, the first direction and the height direction can also refer to any other direction, which is not limited here.

[0091] The first capillary groove 1311 is a capillary structure provided within the first liquid-holding area 131. The first capillary groove 1311 penetrates the circumferential sidewall of the atomizing seat 1, and the first capillary groove 1311 can store the liquid flowing into the first capillary groove 1311 under the action of capillary force. That is to say, the first liquid-holding area 131 is connected to the atomizing chamber 11 through the first capillary groove 1311.

[0092] For example, the first capillary groove 1311 is a microgroove or microchannel structure. These tiny channels can be formed on the surface of the first liquid-collecting region 131 to capture and transport the aerosol generation matrix by utilizing the capillary uplift of liquid in the tiny space. The microgroove can be designed by etching, laser processing, or other micromachining techniques to make the size and shape of the channel suitable for the desired capillary action.

[0093] In some embodiments, a seal 3, such as a silicone sealing sleeve, is covered on the outside of the first capillary groove 1311 to seal the opening of the first capillary groove 1311 facing the atomizing seat 1. In this way, the first capillary groove 1311 only needs to store liquid by capillary force at the opening near the atomizing seat 1.

[0094] The shape of the first capillary groove 1311 is not limited here. For example, it can be rectangular, trapezoidal or semi-circular to adapt to different design requirements and optimize the effect of capillary force.

[0095] The dimensions of the first capillary groove 1311 are not limited here. The dimensions of the groove, including its width and depth, can be optimized according to the viscosity and surface tension of the aerosol generation matrix.

[0096] The air inlet 202 of the ventilation channel 200 is connected to the atomizing chamber 11 through the first liquid collection area 131. The specific location of the ventilation channel 200 is not limited here. For example, it can be opened on the atomizing seat 1, and the ventilation channel 200 extends directly to connect with the first liquid collection area 131. Alternatively, the ventilation channel 200 and the first liquid collection area 131 can be connected by a pipe.

[0097] By setting a first capillary groove 1311 in the first liquid collection zone 131, the liquid flowing into the first capillary groove 1311 is stored by the capillary force of the first capillary groove 1311, thereby realizing the locking of the aerosol generation matrix flowing into the first liquid collection zone 131 in the first liquid collection zone 131.

[0098] In some embodiments, as shown in Figures 1 and 2, a portion of the wall of the first capillary groove 1311 is recessed to form a second capillary groove 1312, which is capable of storing liquid flowing into the second capillary groove 1312 under the action of capillary force.

[0099] The second capillary groove 1312 is a partial recess in the wall of the first capillary groove 1311 to form a capillary structure. In this way, the contact area between the first liquid-holding region 131 and the aerosol generating matrix can be increased through the second capillary groove 1312, thereby improving the liquid-holding effect of the first liquid-holding region 131 on the aerosol generating matrix.

[0100] The specific structure of the second capillary groove 1312 is not specified here.

[0101] For example, the wall of the first capillary groove 1311 has multiple recessed areas spaced apart along the height direction to form a second capillary groove 1312. The first capillary groove 1311 and the second capillary groove together form a serrated capillary structure at the connection between the first capillary groove 1311 and the atomization chamber 11. Thus, when the aerosol generating matrix flows to this location, the aerosol generating matrix fills the serrated structure under the action of capillary force, forming a liquid film that blocks the subsequent outflow of aerosol generating matrix from flowing into the atomization chamber 11, and stores the leaked aerosol generating matrix in the first liquid-collecting area 131.

[0102] A second capillary groove 1312 is formed by a partial indentation in the wall of the first capillary groove 1311, increasing the contact area between the first liquid-holding region 131 and the aerosol generating matrix, thereby improving the liquid-locking effect of the first liquid-holding region 131 on the aerosol generating matrix. The structure is simple. The capillary structure formed by the first capillary groove 1311 and the second capillary groove 1312 can form a liquid film together with the aerosol generating matrix at the connection between the first capillary groove 1311 and the atomization chamber 11, preventing the subsequent outflow of aerosol generating matrix into the atomization chamber 11, and storing the leaked aerosol generating matrix in the first liquid-holding region 131.

[0103] In some embodiments, as shown in Figures 1 and 2, the dimension of the first capillary groove 1311 in the height direction of the atomizing chamber 11 is no greater than 0.6 mm.

[0104] The first capillary groove 1311 has a dimension in the height direction of the atomizing chamber 11 that is no greater than 0.6 mm. For example, it can be 0.1 mm, 0.15 mm, 0.22 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, etc.

[0105] Setting the dimensions of the first capillary groove 1311 within the aforementioned range in the height direction of the atomizing chamber 11 is beneficial for the occurrence of capillary phenomena, enhances the locking effect of capillary force, and makes the aerosol generating matrix flowing into the first capillary groove 1311 more effective in forming a liquid surface, thus effectively locking in any subsequent leakage of the aerosol generating matrix.

[0106] In some embodiments, as shown in Figures 1 and 2, the lowest point of the air inlet 202 of the ventilation channel 200 is not higher than the lowest point of the first capillary groove 1311.

[0107] Here, the lowest point of the air inlet 202 of the ventilation channel 200 is not higher than the lowest point of the first capillary groove 1311. Thus, when the internal and external air pressures of the atomizer 1000 are balanced, the aerosol generation matrix leaking into the first capillary groove 1311 can, under gravity, collect at the air inlet 202 of the ventilation channel 200 and flow back into the liquid storage chamber 302 through the ventilation channel 200 for use by the atomizing core 2 during atomization. This reduces the amount of aerosol generation matrix remaining in the first capillary groove 1311 during normal use, thus reducing waste of the aerosol generation matrix.

[0108] In some embodiments, please refer to Figures 1 to 4. The liquid storage structure 13 includes a second liquid pocket 132. At least a portion of the second liquid pocket 132 is located between the side wall of the atomizing core 2 and the inner wall of the atomizing seat 1. The second liquid pocket 132 is capable of storing the liquid flowing to the second liquid pocket 132 under the action of capillary force.

[0109] The second liquid-holding region 132 is the area in the liquid storage structure 13 used to lock in the liquid. This region uses capillary action to store the aerosol generation matrix flowing into it. The second liquid-holding region 132 is designed to utilize the surface tension between the liquid and solid contact surfaces to maintain the stable storage of the aerosol generation matrix through capillary action, thereby locking in any overflowing aerosol generation matrix.

[0110] The second liquid-collecting zone 132 is located between the side wall of the atomizing core 2 and the inner wall of the atomizing seat 1. By utilizing the spaced arrangement between the side wall of the atomizing core 2 and the inner wall of the atomizing seat 1, micro-aerosols flowing into this zone can also be captured and stored using capillary force to generate a matrix.

[0111] The specific structure of the second liquid pocket 132 is not specified here.

[0112] It should be noted that because the atomizing core 2 has a through-hole microporous structure, which connects the liquid storage chamber 302 and the atomizing chamber 11, when the internal and external air pressures of the atomizer 1000 are balanced, the aerosol generation matrix in the liquid storage chamber 302 will not flow from the microporous structure to the atomizing chamber 11 under the action of capillary force and air pressure.

[0113] When the atomizer 1000 is in normal use, the external negative pressure can drive the aerosol generating matrix in the atomization chamber 11 to flow out in a set amount. When it flows out to the atomization surface, the aerosol generating matrix is ​​atomized and flows out from the air outlet channel 301 in the form of aerosol. The aerosol generating matrix will not remain in the atomization chamber 11 in large quantities.

[0114] However, during transportation and storage, changes in the external environment cause the aerosol generating matrix in the liquid storage chamber 302 to flow out from the microporous structure. At this time, the atomizing core 2 is not working and cannot consume these outflowing aerosol generating matrices, resulting in leakage of the aerosol generating matrix.

[0115] The second liquid-collecting zone 132 here can store the aerosol generation matrix that leaks out from the microporous structure. Since the second liquid-collecting zone 132 is located between the side wall of the atomizing core 2 and the inner wall of the atomizing seat 1, the microporous structure is connected to the second liquid-collecting zone 132. During normal use, the leaked aerosol generation matrix can flow back to the liquid storage chamber 302 through the microporous structure of the atomizing core 2.

[0116] By setting up a second liquid-holding zone 132, the capillary effect between the structure of the second liquid-holding zone 132 and the liquid is utilized to store the aerosol generation matrix that cannot be consumed when flowing into the atomizer 1000 chamber. No additional liquid-locking structure is required, resulting in a simple structure, convenient setup, and reduced generation costs.

[0117] In some embodiments, the liquid storage structure 13 includes a second liquid-collecting area 132, and the ventilation channel 200 is disposed within the second liquid-collecting area 132, which simplifies the liquid storage structure 13 and reduces production costs. In some cases, such as for an atomizer 1000 with high requirements for leak prevention, the liquid storage structure 13 may include a first liquid-collecting area 131 and a second liquid-collecting area 132, with the ventilation channel 200 disposed within the first liquid-collecting area 131. The arrangement of the two liquid-collecting areas helps to improve the leak prevention capability of the atomizer 1000.

[0118] In some embodiments, please refer to Figures 1 to 4. The second liquid-collecting area 132 includes a third capillary groove 1321. The atomizing assembly 100 includes a seal 3. The seal 3 is sandwiched between the atomizing core 2 and the atomizing seat 1. The seal 3, the atomizing core 2, and the atomizing seat 1 define the third capillary groove 1321. The second liquid-collecting area 132 is in communication with the atomizing chamber 11. The air inlet 202 of the ventilation channel 200 is in communication with the second liquid-collecting area 132.

[0119] The seal 3 is used for sealing the connection between the atomizing core 2 and the atomizing base 1, ensuring that the aerosol generation matrix will not leak during atomization, and also helps to maintain the internal pressure of the atomizer 1000 and prevent external contaminants from entering.

[0120] The sealing element 3 is sandwiched between the atomizing core 2 and the atomizing seat 1. That is to say, the sealing element 3, the atomizing core 2 and the atomizing seat 1 define a "U" shaped groove. This "U" shaped groove is the third capillary groove 1321. The sealing element 3 forms the bottom of the third capillary groove 1321, and the side wall of the atomizing core 2 and the inner wall of the atomizing seat 1 form the groove wall of the third capillary groove 1321.

[0121] The specific material of the sealing element 3 is not limited here. The sealing element 3 should have a certain degree of elasticity and deform under the compression of the atomizing core 2 and the atomizing seat 1 to fill the gap between the atomizing core 2 and the atomizing seat 1, thereby achieving a sealing effect. For example, the sealing element 3 is a silicone pad.

[0122] The third capillary groove 1321 is a capillary structure provided within the second liquid-collecting region 132. The third capillary groove 1321 can store the liquid flowing into the third capillary groove 1321 under the action of capillary force.

[0123] The shape of the third capillary groove 1321 is not limited here. For example, it can be rectangular, trapezoidal or semi-circular to adapt to different design requirements and optimize the effect of capillary force.

[0124] The dimensions of the third capillary groove 1321 are not limited here. The dimensions of the groove, including its width and depth, can be optimized according to the viscosity and surface tension of the aerosol generation matrix.

[0125] Since the third capillary groove 1321 is formed by the seal 3, the atomizing core 2 and the atomizing seat 1, the shape and size of the third capillary groove 1321 are determined by the seal 3, the atomizing core 2 and the atomizing seat 1.

[0126] The specific structure of the ventilation channel 200 is not limited here. For example, a channel communicating with the second liquid collection area 132 can be opened on the atomizing seat 1 to form the ventilation channel 200. This facilitates the start of the ventilation channel 200. At the same time, since the atomizing seat 1 is a rigid structure, the flow cross-sectional area of ​​the ventilation channel 200 will not be affected by external forces.

[0127] Alternatively, a channel can be opened on the seal 3 to connect with the second liquid-filled area 132 to form a ventilation channel 200.

[0128] Alternatively, a ventilation channel 200 can be formed by opening a channel together between the atomizing seat 1 and the sealing element 3.

[0129] By setting a third capillary groove 1321 in the second liquid collection zone 132, the liquid flowing into the third capillary groove 1321 is stored by the capillary force of the third capillary groove 1321, thereby realizing the locking of the aerosol generation matrix flowing into the second liquid collection zone 132 in the second liquid collection zone 132.

[0130] In some embodiments, please refer to Figures 1 to 4, the inner wall of the seal 3 is provided with a ventilation groove 31, and the ventilation groove 31 and the surface of the atomizing core 2 define a ventilation channel 200.

[0131] The ventilation groove 31 is part of the inner wall of the seal 3. It is designed in a concave shape and together with the surface of the atomizing core 2, it defines the ventilation channel 200.

[0132] The ventilation groove 31 and the surface of the atomizing core 2 define a ventilation channel 200. In other words, the surface of the atomizing core 2 seals the ventilation groove 31, thus forming a ventilation channel 200.

[0133] It is understandable that the ventilation channel 200 is connected to the liquid storage chamber 302 and the atomizing chamber 11. That is to say, the two ends of the ventilation groove 31 provided on the inner wall of the sealing member 3 extend to the liquid storage chamber 302 and the atomizing channel respectively, and are connected.

[0134] The location of the ventilation slot 31 is not limited here, and will be determined according to the actual situation.

[0135] For example, the ventilation groove 31 is disposed on the sealing member 3 on the side near the atomizing surface of the atomizing core 2, and the ventilation groove 31 together with the atomizing surface forms the ventilation channel 200. In this way, the formation of the ventilation groove 31 can be facilitated.

[0136] By providing an air exchange groove 31 on the inner wall of the seal 3, the air exchange groove 31 and the surface of the atomizing core 2 define an air exchange channel 200, which can shorten the length of the air exchange channel 200, simplify the structure, and reduce the difficulty of setting the air exchange channel 200.

[0137] In some embodiments, as shown in Figures 1 to 4, the width of the third capillary groove 1321 is no greater than 0.6 mm.

[0138] The width of the third capillary groove 1321 is no greater than 0.6 mm, for example, it can be 0.1 mm, 0.15 mm, 0.22 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, etc.

[0139] It should be noted that the width here refers to the distance between the side wall of the atomizing core 2 that constitutes the third capillary groove 1321 and the inner wall of the atomizing seat 1.

[0140] Setting the size of the third capillary groove 1321 within the above range is beneficial to the occurrence of capillary phenomena, improves the locking effect of capillary force, and makes the aerosol generating matrix flowing into the third capillary groove 1321 more effective in forming a liquid film, thus effectively locking in the subsequently leaked aerosol generating matrix.

[0141] In some embodiments, as shown in Figures 1 to 4, the lowest point of the air inlet 202 of the ventilation channel 200 is not higher than the lowest point of the third capillary groove 1321.

[0142] For example, the air inlet 202 of the ventilation channel 200 is disposed in the third capillary groove 1321, and the lowest point of the air inlet 202 of the ventilation channel 200 is flush with the lowest point of the third capillary groove 1321.

[0143] Here, the lowest point of the air inlet 202 of the ventilation channel 200 is not higher than the lowest point of the third capillary groove 1321. Thus, when the internal and external air pressures of the atomizer 1000 are balanced, the aerosol generation matrix leaking into the third capillary groove 1321 can, under gravity, collect at the air inlet 202 of the ventilation channel 200 and flow back into the liquid storage chamber 302 through the ventilation channel 200 for use by the atomizing core 2 during atomization. This reduces the amount of aerosol generation matrix remaining in the third capillary groove 1321 during normal use, thus reducing waste of the aerosol generation matrix.

[0144] In some embodiments, please refer to Figures 1 to 5. The atomizing base 1 is provided with an air inlet 14, which penetrates the circumferential sidewall of the atomizing base 1. The atomizing chamber 11 can communicate with the outside of the atomizer 1000 through the air inlet 14. In the height direction of the atomizer 1000, the lowest point of the air inlet 14 is higher than the top surface of the atomizing core 2.

[0145] The air inlet 14 is a channel opened on the atomizer 1000 to introduce external air. The air inlet 14 connects the atomizing chamber 11 with the outside of the atomizer 1000, which helps to form the airflow required for atomization.

[0146] The lowest point of the air inlet 14 is higher than the top surface of the atomizing core 2. Thus, the large volume of aerosol generating matrix flowing out of the surface of the atomizing core 2 is higher than the top surface of the atomizing core 2. The inner wall of the atomizing seat 1 can block the aerosol generating matrix, so that the large volume of aerosol generating matrix can be stored in the atomizing chamber 11.

[0147] It is understandable that the greater the distance between the lowest point of the air inlet 14 and the top surface of the atomizing core 2, the greater the storage capacity of the atomizing seat 1 for the aerosol generation matrix in the atomizing chamber 11.

[0148] Meanwhile, the closer the lowest point of the air inlet 14 is to the top surface of the atomizing core 2, the more fully the external airflow contacts the atomizing surface of the atomizing core 2, and the better the taste of the aerosol produced.

[0149] Therefore, the distance between the lowest point of the air inlet 14 and the top surface of the atomizing core 2 needs to be considered in conjunction with the amount of aerosol generation matrix, i.e., the aerosol taste.

[0150] It should be noted that, for the embodiment with the second liquid-collecting area 132, the second liquid-collecting area 132 refers to the space defined by the atomizing chamber 11 formed by the inner wall of the atomizing seat 1 and the third capillary groove 1321 from the horizontal plane of the lowest point of the air inlet 14 to the top surface of the atomizing core 2.

[0151] In some embodiments, the distance between the lowest point of the air inlet 14 and the top surface of the atomizing core 2 is no more than 1 mm, for example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc.

[0152] The shape and size of the air intake 14 are not limited here. For example, it can be circular, elliptical or slit-shaped. The size of the air intake 14 will affect the airflow and atomization effect.

[0153] The position and number of air inlets 14 can be distributed on the circumferential sidewall of the atomizer base 1 according to the size and design requirements of the atomizer 1000, and the number can be adjusted as needed.

[0154] By setting the air inlet 202, the airflow within the atomization chamber 11 can be increased, thereby improving the atomization efficiency of the aerosol generation matrix. The fact that the lowest point of the air inlet 14 is higher than the top surface of the atomizing core 2 also allows for the storage of a large volume of aerosol generation matrix within the atomization chamber 11.

[0155] In some embodiments, please refer to Figures 1 to 5. The air inlet 14 is an oblong hole extending along the height direction of the atomizer 1000, and the width of the air inlet 14 is not greater than 0.6 mm.

[0156] The width of the air inlet 14 is no greater than 0.6mm, for example, it can be 0.1mm, 0.15mm, 0.22mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, etc.

[0157] Setting the size of the air inlet 14 within the above range is beneficial to the occurrence of capillary action, improves the locking effect of capillary force, and makes the aerosol generating matrix flowing into the third capillary tank 1321 more liquid to form a liquid surface, thus effectively locking in the subsequently leaked aerosol generating matrix.

[0158] On the other hand, by configuring the air inlet 14 as an oblong orifice extending along the height direction of the atomizer 1000, when a large volume of aerosol generating matrix flows into the atomization chamber 11, the oblong orifice with a capillary structure below the liquid surface of the aerosol generating matrix can form a liquid film under the action of capillary force, sealing the portion of the oblong orifice below the liquid surface of the aerosol generating matrix and preventing the outflow of the aerosol generating matrix. At the same time, the portion of the oblong orifice with a capillary structure below the liquid surface of the aerosol generating matrix is ​​still connected to the outside of the atomizer 1000, and can still guide external air into the atomization chamber 11. The structure is simple and suitable for situations where a large volume of aerosol matrix flows out.

[0159] This disclosure provides an atomizer 1000. Referring to Figures 6 to 8, the atomizer 1000 includes a housing assembly 300 and an atomizing assembly 100. The housing assembly 300 has an air outlet channel 301 and a liquid storage chamber 302 inside, the liquid storage chamber 302 being used to store an aerosol generation matrix. The atomizing assembly 100 includes an atomizing seat 1 and an atomizing core 2. At least a portion of the atomizing seat 1 is disposed within the housing assembly 300, and the atomizing core 2 is disposed within the atomizing seat 1. The atomizing seat 1 has an atomizing chamber 11 and a liquid inlet channel 12, the atomizing chamber 11 communicating with the air outlet channel 301. 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 are connected through the liquid-locking port 123. The first liquid inlet section 121 communicates with the liquid storage chamber 302, and the second liquid inlet section 122 is 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.

[0160] The housing assembly 300 may have a liquid storage chamber 302 inside, which may be defined by the housing assembly 300 or by the housing assembly 300 and the atomizing seat 1.

[0161] The housing assembly 300 is the outer housing of the atomizer 1000, and an air outlet channel 301 is formed inside it. At least a portion of the atomizing base 1 is disposed within the housing assembly 300.

[0162] The air outlet passage 301 can be located in the middle area within the housing assembly 300, or it can be located on the side of the middle area of ​​the housing assembly 300.

[0163] In some embodiments, the top of the atomizing seat 1 and the inner sidewall of the housing assembly 300 define a liquid storage chamber 302 for storing the aerosol generation matrix, and the liquid storage chamber 302 is arranged around the gas outlet channel 301.

[0164] In other embodiments, a liquid storage cavity 302 may be formed inside the housing assembly 300.

[0165] 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.

[0166] For example, the fact that at least a portion of the atomizer base 1 is disposed within the housing assembly 300 can mean that a portion of the structure of the atomizer base 1 is disposed within the housing assembly 300, or it can mean that the entire structure of the atomizer base 1 is disposed within the housing assembly 300.

[0167] For example, the atomizing base 1 has an air intake channel that connects the outside world and the atomizing chamber 11.

[0168] 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 302 and the atomizing chamber 11, and the atomizing chamber 11 is connected to the air outlet channel 301. The aerosol generating matrix in the liquid storage chamber 302 enters the atomizing core 2 through the liquid inlet channel 12 for atomization. The aerosol formed after atomization flows through the air outlet channel 301 along with the air flowing in through the air inlet channel and is discharged to the outside through the air outlet for user use.

[0169] The atomizing core 2 is used to absorb the aerosol generation matrix and atomize the aerosol generation matrix to form an aerosol.

[0170] 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 cavity 302 is the liquid absorption surface, and the side of the atomizing core 2 that connects the microporous structure to the atomizing cavity 11 is the atomizing surface.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] The atomizing chamber 11 is a space within the atomizing base 1, connected to the air outlet channel 301, 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.

[0175] The specific structure of the atomizing chamber 11 is determined based on the actual situation and is not limited here.

[0176] The liquid inlet channel 12 is a channel connecting the liquid storage chamber 302 and the atomizing core 2. The liquid inlet channel 12 transports the aerosol generation matrix from the liquid storage chamber 302 to the atomizing core 2.

[0177] 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 302. 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 302 to the subsequent atomization process.

[0178] 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.

[0179] 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 302 flows through the liquid lock port 123 with a smaller flow cross-sectional area, it will limit the flow velocity of the liquid.

[0180] 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.

[0181] "Inverted state" means that in this state, the liquid storage chamber 302 is located below the atomizing component 100, and the aerosol generation matrix in the liquid storage chamber 302 cannot enter the atomizing core 2 of the atomizing component 100 under the action of gravity or other forces.

[0182] "Tilted state" refers to a state in which the liquid storage chamber 302 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°.

[0183] 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.

[0184] 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.

[0185] The specific structure of the liquid-locking port 123 is not limited here; any structure with the above functions is acceptable.

[0186] 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.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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.

[0191] The atomizer 1000 provided in this embodiment of the present disclosure, by providing a first liquid inlet section 121 and a second liquid inlet section 122 connected within the liquid inlet channel 12, wherein the first liquid inlet section 121 is connected to the liquid storage chamber 302 and the second liquid inlet section 122 is in liquid communication with the atomizing core 2, can realize the delivery of the aerosol generating matrix in the liquid storage chamber 302 to the atomizing core 2, and 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 lock port 123, the cross-sectional area of ​​which is smaller than at least part of the flow cross-sectional area of ​​the first liquid inlet section 121. Thus, the bubbles formed by the aerosol generating matrix during the flow can accumulate at the liquid lock port 123 to form an airlock, which is used 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 lock 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.

[0192] In some embodiments, please refer to Figures 6 and 7, the distance between any two points of the liquid-locking port 123 in the circumferential direction is no greater than 3 mm.

[0193] 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.

[0194] 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.

[0195] 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.

[0196] 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.

[0197] In some embodiments, please refer to Figures 6 and 7, 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.

[0198] 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.

[0199] In some embodiments, please refer to Figures 6 to 8. 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.

[0200] 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.

[0201] 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.

[0202] 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.

[0203] 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.

[0204] In some embodiments, please refer to Figures 6 to 8, the sidewall of the liquid inlet channel is provided with a first capillary groove, which is connected to the second liquid inlet section.

[0205] 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.

[0206] 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.

[0207] 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.

[0208] 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.

[0209] For example, wettability is increased by increasing the surface area of ​​the first capillary groove, thereby improving the efficiency of liquid transport.

[0210] 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.

[0211] 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.

[0212] In some embodiments, please refer to Figures 6 to 8. The atomizing seat 1 includes an atomizing top seat 15 and an atomizing base 16. The atomizing top seat 15 is located on the top side of the atomizing base 16. The atomizing top seat 15 is provided with a first liquid inlet section, and the atomizing base 16 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.

[0213] The atomizing top seat 15 is located on top of the atomizing base 16 and is part of the atomizing base 1. The atomizing top seat 15 is provided with a first liquid inlet section. The atomizing top seat 15 is used to guide the aerosol generation matrix in the liquid storage chamber to the atomizing core.

[0214] The nebulizer base 16 is located below the nebulizer base 1, and the nebulizer base 16 is provided with a second liquid inlet section. The nebulizer base 16 is used to guide the liquid medicine in the first liquid inlet section to the nebulizer core.

[0215] The specific structure of the atomizing top seat 15 and the atomizing base 16 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.

[0216] For example, both the atomizing top seat 15 and the atomizing base 16 are integrally molded structures, such as by injection molding. The atomizing top seat 15 and the atomizing base 16 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.

[0217] For example, the connection between the atomizing top seat 15 and the atomizing base 16 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 lock port 123 are not affected by external factors, and ensuring the liquid lock effect of the liquid lock port 123.

[0218] The atomizing base 1 is composed of an atomizing top seat 15 and an atomizing base 16. The atomizing top seat 15 is provided with a first liquid inlet section, and the atomizing base 16 is provided with a second liquid inlet section. The complex structure of the atomizing base 16 is broken down into two easily moldable parts, which reduces the difficulty of the production process of the atomizing base 1, and helps to improve the yield rate and production efficiency of the atomizing base 1.

[0219] In some embodiments, please refer to Figures 6 to 8, a guide column 161 is provided protruding from the bottom wall of the second liquid inlet section, and the guide column 161 extends toward the liquid absorption surface of the atomizing core.

[0220] The guide column 161 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 161 is used to more effectively guide the aerosol generating matrix in the second liquid inlet section to the atomizing core, reduce the residue of the aerosol generating matrix in the second liquid inlet section, and improve atomization efficiency.

[0221] The specific structure of the guide column 161 is not limited here. By changing the shape and angle of the guide column 161, the path of the liquid flow to the atomizing core can be further optimized, the resistance and dead zone of the liquid flow can be reduced, and the atomization efficiency can be improved.

[0222] In some embodiments, multi-stage guide columns 161 or guide grooves may be designed to increase the surface area of ​​contact between the liquid and the atomizing core, thereby promoting a more uniform atomization effect.

[0223] For example, the guide column 161 is frustum-shaped, which facilitates demolding of the guide column during the mold forming process.

[0224] By protruding the guide column 161 on 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 the atomization efficiency.

[0225] In some embodiments, please refer to Figures 6 to 8, the distance between the guide column 161 and the liquid absorption surface of the atomizing core is no greater than 0.15 mm.

[0226] The distance between the guide column 161 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.

[0227] The distance between the guide column 161 and the liquid absorption surface of the atomizing core is set within this range. The gap formed by this tiny distance can use capillary force to attract the aerosol generation matrix on the guide column 161 to the liquid absorption surface of the atomizing core.

[0228] In some embodiments, please refer to Figures 6 to 8. The number of guide columns 161 is multiple, and the spacing between each guide column 161 is in the range of 0.6 mm to 0.8 mm.

[0229] The spacing between each guide column 161 ranges from 0.6mm to 0.8mm, for example, it can be 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, etc.

[0230] The arrangement of multiple guide columns 161 can improve the guiding effect on the aerosol generation matrix. On the other hand, the spacing between each guide column 161 is within the aforementioned range, and the gaps between each guide column 161 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.

[0231] Understandably, the more flow guide columns 161 there are, the more gaps are formed between them, and the better the liquid-locking effect of the flow guide columns 161 on the aerosol generation matrix. The specific number of flow guide columns 161 is not limited here.

[0232] In some embodiments, as shown in Figures 6 to 8, the height of the guide column 161 is no greater than 1.1 mm.

[0233] The height of the guide column 161 is no more than 1.1mm, for example, it can be 0.1mm, 0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.1mm, etc.

[0234] Since capillary action has limited ability to attract liquid, the height of the guide column 161 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 161 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.

[0235] In some embodiments, as shown in Figures 6 to 8, the bottom wall of the second inlet section is provided with a second capillary groove.

[0236] 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.

[0237] 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.

[0238] For example, wettability is increased by increasing the surface area of ​​the second capillary groove, thereby improving the efficiency of liquid transport.

[0239] 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.

[0240] For example, the second capillary groove extends to the guide column 161. 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 161, and then to the atomizing core, thereby improving the liquid transfer efficiency.

[0241] By providing a second capillary groove on the bottom wall of the second liquid inlet section, when inverted, the second capillary groove utilizes capillary action to assist the liquid-locking port 123 in locking the aerosol generation matrix within the second liquid inlet section. Furthermore, the second capillary groove can also guide the aerosol generation matrix within the second liquid inlet section to flow through the guide column 161, improving liquid transfer efficiency.

[0242] In some embodiments, as shown in Figures 6 to 8, 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.

[0243] 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.

[0244] 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.

[0245] The width here refers to the distance between the opposing surfaces that make up the second capillary groove.

[0246] 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.

[0247] It should be noted that the length of the second capillary groove is not limited here.

[0248] 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.

[0249] In some embodiments, please refer to Figures 6 to 8, the width of the first capillary groove is not greater than 0.6 mm, and the depth of the first capillary groove is not greater than 0.6 mm.

[0250] 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.

[0251] 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.

[0252] The width here refers to the distance between the opposing surfaces that make up the first capillary groove.

[0253] 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.

[0254] It should be noted here that the length of the first capillary groove is not limited.

[0255] 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.
