Liquid storage atomization device and aerosol generation device

Abstract

This application relates to the field of atomizer technology, and more particularly to a liquid storage atomizing device and an aerosol generating device. The liquid storage atomizing device includes a liquid storage component, a pressure reducing component, and an atomizing component. The liquid storage component has a liquid storage chamber and an air passage passing through the liquid storage chamber. The pressure reducing component is housed in the liquid storage chamber and has an interconnected pressure reducing channel and a fixed chamber, with the fixed chamber connected to the liquid storage chamber via the pressure reducing channel. The atomizing component is housed in the fixed chamber and is connected to the fixed chamber, and is also connected to the air passage. The atomizing matrix in the liquid storage chamber enters the atomizing component after passing through the pressure reducing channel. The atomizing component heats the atomizing matrix to generate an aerosol in the air passage. During its flow, the atomizing matrix in the liquid storage chamber is buffered by the pressure reducing channel to reduce the flow rate of the atomizing matrix, effectively reducing the pressure of the atomizing matrix from the liquid storage chamber to the atomizing component. This prevents excessive atomizing matrix from entering the atomizing component, thereby preventing atomizing matrix leakage.

Description

Technical Field

[0001] This application relates to the field of atomizer technology, and more particularly to a liquid storage atomizing device and an aerosol generating device. Background Technology

[0002] An aerosol generating device is a product that atomizes a matrix into an aerosol through methods such as mist heating. When a user inhales, the aerosol flows with the airflow generated by the user's inhalation and flows out of the aerosol generating device. The aerosol generating device includes a storage chamber for storing the atomized matrix, and an atomizing component is installed within the storage chamber. The atomizing component heats the atomized matrix within the storage chamber to generate an aerosol.

[0003] In related technologies, the atomizing component is immersed in a liquid storage chamber. The atomizing component has an atomization channel communicating with the outside of the aerosol generating device. The outer tube of the atomizing component is designed with a small liquid inlet hole. The atomizing matrix in the liquid storage chamber flows to the atomizing component through the liquid inlet hole. The atomizing core in the atomization channel can atomize the atomizing matrix flowing into the atomization channel from the liquid storage chamber through the liquid inlet hole, and generate aerosol in the atomization channel. When the air pressure inside the liquid storage chamber is higher than the air pressure outside the liquid storage chamber, the atomizing matrix can easily pass directly through the liquid inlet hole, resulting in an excessive amount of atomizing matrix entering the atomization channel. Alternatively, the atomizing matrix may permeate to the center of the atomization channel under pressure, causing some of the atomizing matrix to not be atomized by the atomizing core and to flow out of the aerosol generating device from the atomization channel, resulting in easy leakage of the atomizing matrix.

Alternatively, the atomizing matrix may permeate to the center of the atomization channel under pressure, causing some of the atomizing matrix to not be atomized by the atomizing core and to flow out of the aerosol generating device from the atomization channel, resulting in easy leakage of the atomizing matrix.

[0058] In view of the above problems, this application provides a liquid atomizing device and an aerosol generating device to solve the technical problem of easy leakage of atomized matrix.

[0059] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0060] Please refer to Figures 1 to 12 This application provides a liquid storage atomizing device, including a liquid storage component 1, a pressure reducing component 2, and an atomizing component 3.

[0061] The liquid storage assembly 1 has a liquid storage chamber 11 and an air passage 12 penetrating the liquid storage chamber 11. The pressure reducing assembly 2 is housed in the liquid storage chamber 11 and has an interconnected pressure reducing channel 21 and a fixed cavity 221, with the fixed cavity 221 connected to the liquid storage chamber 11 via the pressure reducing channel 21. The atomizing assembly 3 is housed in and connected to the fixed cavity 221, and is also connected to the air passage 12. The atomizing matrix in the liquid storage chamber 11 enters the fixed cavity 221 after passing through the pressure reducing channel 21, and the atomizing assembly 3 heats the atomizing matrix to generate an aerosol in the air passage 12.

[0062] Please refer to Figures 3 to 7 In some embodiments, the pressure-reducing component 2 includes a fixed cylinder 22, which has a fixed cavity 221. The fixed cylinder 22 has an air inlet 222 and an air outlet 223 communicating with the fixed cavity 221. The air outlet 223 is connected to the air passage 12. The atomizing component 3 is housed in the fixed cavity 221 and has an atomizing channel 31. One end of the atomizing channel 31 communicates with the air inlet 222, and the other end communicates with the air outlet 223. The atomizing component 3 includes an atomizing core located in the atomizing channel 31. The atomizing channel 31 communicates with the fixed cavity 221, allowing the atomizing substrate in the fixed cavity 221 to enter the atomizing channel 31 and contact the atomizing core. The atomizing core heats the atomizing substrate and generates an aerosol in the atomizing channel 31. The air passage 12 communicates with the atomizing channel 31, allowing the aerosol to flow into the air passage 12.

[0063] Please refer to Figures 3 to 7 It should be noted that the fixed cylinder 22 has a first liquid passage hole 224, which communicates with the fixed cavity 221. The pressure reducing channel 21 is located on the periphery of the fixed cylinder 22, and the first liquid passage hole 224 also communicates with the pressure reducing channel 21, so that the fixed cavity 221 and the pressure reducing channel 21 are interconnected through the first liquid passage hole 224. The pressure reducing assembly 2 also includes a liquid passage cylinder 23, which is inserted into the fixed cylinder 22. The end opening of the liquid passage cylinder 23 communicates with the liquid storage cavity 11. The liquid passage cylinder 23 has a second liquid passage hole 231, which communicates with the inner cavity of the liquid passage cylinder 23 and the pressure reducing channel 21, so that the pressure reducing channel 21 communicates with the liquid storage cavity 11 through the second liquid passage hole 231 and the inner cavity of the liquid passage cylinder 23, thereby enabling the pressure reducing channel 21 to communicate with the liquid storage cavity 11, and thus enabling the fixed cavity 221 to communicate with the liquid storage cavity 11 through the pressure reducing channel 21. The path of the atomizing matrix from the storage chamber 11 into the fixed chamber 221 is as follows: storage chamber 11 → liquid passage cylinder 23 → second liquid passage hole 231 → pressure reducing channel 21 → first liquid passage hole 224 → fixed chamber 221.

[0064] In the liquid storage atomizing device provided in the first aspect embodiment of this application, since the atomizing matrix in the liquid storage chamber 11 enters the fixed chamber 221 after passing through the pressure reducing channel 21, the travel of the atomizing matrix can be extended, so that the kinetic energy of the atomizing matrix is ​​consumed, thereby reducing the flow rate of the atomizing matrix flowing into the fixed chamber 221 from the pressure reducing channel 21. This effectively reduces the pressure of the atomizing matrix from the pressure reducing channel 21 to the atomizing component 3, prevents excessive atomizing matrix from entering the atomizing component 3, and prevents the atomizing matrix from penetrating to the center of the atomizing channel 31, thereby preventing atomizing matrix leakage.

[0065] Please refer to Figure 3 In some embodiments, the liquid storage assembly 1 includes a cup body 13 and a first seal 14. One end of the cup body 13 has an opening, and the first seal 14 is inserted into the cup body 13 through the opening. The first seal 14 and the cup body 13 together form a liquid storage cavity 11. The pressure reducing assembly 2 is inserted into the cup body 13 through the opening. The liquid passing cylinder 23 passes through the first seal 14 so that the liquid passing cylinder 23 communicates with the liquid storage cavity 11.

[0066] In the above embodiment, the liquid storage component 1 is disassembled into a cup body 13 and a first sealing member 14, which facilitates the disassembly and assembly of the liquid storage component 1.

[0067] Please refer to Figure 3 In some embodiments, the cup body 13 includes a cup cylinder 131 and a second sealing member 132. The cup cylinder 131 is a cylindrical structure with openings at both ends. The second sealing member 132 is inserted into the cup cylinder 131 through one of the openings. The cup cylinder 131 and the second sealing member 132 enclose each other to form a cup body 13 with an opening at one end. The first sealing member 14 is inserted into the cup body 13 through the opening of the cup cylinder 131 away from the second sealing member 132. The pressure reducing component 2 is inserted into the cup body 13 through the opening of the cup cylinder 131 away from the second sealing member 132.

[0068] In the above embodiment, by splitting the cup body 13 into a cup cylinder 131 and a second sealing member 132, it is convenient to disassemble and assemble the liquid storage assembly 1.

[0069] Please refer to Figure 3 In some embodiments, the liquid storage assembly 1 further includes an air guide tube 15, one end of which is inserted into the first seal 14 and communicates with the atomization channel 31, and the other end of which is inserted into the second seal 132, and the air guide tube 15 forms an air passage 12.

[0070] Please refer to Figure 3In some embodiments, the pressure-reducing channel 21 includes a slow-flow channel 211 and a confluence chamber 212. The slow-flow channel 211 is connected to the liquid storage chamber 11. The confluence chamber 212 is connected to both the slow-flow channel 211 and the fixed chamber 221. The slow-flow channel 211 is connected to the fixed chamber 221 via the confluence chamber 212, and the atomized matrix in the liquid storage chamber 11 flows through the slow-flow channel 211 and converges into the confluence chamber 212.

[0071] In the above embodiment, the atomizing matrix in the storage chamber 11 converges into the manifold 212 after passing through the slow-flow channel 211. The manifold 212 can temporarily store a certain amount of atomizing matrix. The atomizing matrix gathered in the manifold 212 can form a barrier that is difficult for the atomizing matrix flowing into the manifold 212 through the slow-flow channel 211 to penetrate. This allows the atomizing matrix flowing out of the slow-flow channel 211 to first converge in the manifold 212 before flowing into the fixed chamber 221. This enables the manifold 212 to provide a stable liquid flow to the fixed chamber 221, thereby balancing the liquid supply pressure to the fixed chamber 221 and reducing the risk of atomizing matrix leakage.

[0072] Please refer to Figure 3 , Figure 5 and Figure 6 In the above embodiment, the first liquid passage 224 is opened on the inner wall of the manifold 212. The manifold 212 is connected to the fixed cavity 221 through the first liquid passage 224. The path of the atomized matrix from the storage cavity 11 into the fixed cavity 221 is: storage cavity 11 → liquid passage cylinder 23 → second liquid passage 231 → slow flow channel 211 → manifold 212 → first liquid passage 224 → fixed cavity 221.

[0073] Please refer to Figure 4 In some embodiments, the pressure reducing channel 21 further includes a transition cavity 213, which is connected to both the liquid storage cavity 11 and the slow-flow channel 211. The slow-flow channel 211 is connected to the liquid storage cavity 11 through the transition cavity 213.

[0074] In the above embodiment, the slow-flow channel 211 is connected to the liquid storage chamber 11 through the transition chamber 213. The atomized matrix in the liquid storage chamber 11 first collects in the transition chamber 213 and then flows to the slow-flow channel 211. The transition chamber 213 can temporarily store a certain amount of atomized matrix. The atomized matrix collected in the transition chamber 213 can form a barrier that is difficult for the atomized matrix in the liquid storage chamber 11 to penetrate, so that the transition chamber 213 can provide a stable liquid flow to the slow-flow channel 211, thereby balancing the liquid supply pressure to the slow-flow channel 211. This allows the atomized matrix in the slow-flow channel 211 to flow stably and provide a stable liquid flow to the fixed chamber 221, thereby balancing the liquid supply pressure to the fixed chamber 221 and reducing the risk of atomized matrix leakage.

[0075] Please refer to Figure 4 , Figure 5 and Figure 7 In the above embodiment, the second liquid passage 231 is opened on the inner wall of the transition cavity 213. The transition cavity 213 is connected to the storage cavity 11 through the second liquid passage 231. The path of the atomized matrix from the storage cavity 11 into the fixed cavity 221 is: storage cavity 11 → liquid passage cylinder 23 → second liquid passage 231 → transition cavity 213 → slow flow channel 211 → confluence cavity 212 → first liquid passage 224 → fixed cavity 221.

[0076] Please refer to Figures 3 to 7 In some embodiments, the liquid storage atomizing device further includes a plurality of first partitions 4. The plurality of first partitions 4 are arranged around at least one of the inner wall of the liquid storage chamber 11 (the inner wall of the cup 131) and the outer wall of the pressure reducing assembly 2, with the plurality of first partitions 4 spaced apart sequentially along the length of the liquid storage chamber 11. Two adjacent first partitions 4 form a partition groove 41, and each first partition 4 has a flow hole 42 connecting the two adjacent partition grooves 41, with the plurality of flow holes 42 staggered. The slow-flow channel 211 is formed by the plurality of first partitions 4, the outer wall of the pressure reducing assembly 2, and the inner wall of the liquid storage chamber 11 (the inner wall of the cup 131).

[0077] In the above embodiment, two adjacent first separators 4 form a separator groove 41, and the separator groove 41 surrounds the pressure reducing assembly 2. Each first separator 4 is provided with a flow hole 42 that connects the two adjacent separator grooves 41, so that the atomizing matrix can flow through the separator groove 41 and the flow hole 42 in sequence, thereby allowing the atomizing matrix to flow through the slow flow channel 211.

[0078] In the above embodiment, the misalignment of the multiple flow holes 42 means that the flow holes 42 are spaced apart along the direction surrounding the pressure reducing component 2, so that the atomizing matrix can flow a certain distance in the partition groove 41 before flowing into the next partition groove 41 through the flow holes 42. This can extend the length of the slow-flow channel 211, thereby extending the travel distance of the atomizing matrix in the slow-flow channel 211. The kinetic energy of the atomizing matrix in the slow-flow channel 211 has more opportunities to be consumed, thereby further reducing the flow velocity of the atomizing matrix. Furthermore, the misalignment of the multiple flow holes 42 can increase the turning points in the flow path of the atomizing matrix, thereby increasing the obstacles in the flow path of the atomizing matrix, thereby increasing the opportunity for the kinetic energy of the atomizing matrix in the slow-flow channel 211 to be consumed, thereby further reducing the flow velocity of the atomizing matrix.

[0079] Please refer to Figures 3 to 7In some embodiments, multiple first partitions 4 are arranged around the outer wall of the pressure-reducing assembly 2, and no first partitions 4 are provided on the inner wall of the liquid storage cavity 11 (the inner wall of the cup 131), so that there is no structure on the inner wall of the liquid storage cavity 11 (the inner wall of the cup 131) that obstructs the movement of the first sealing member 14. The first sealing member 14 can be smoothly inserted into the cup 131, so as to facilitate the assembly and disassembly of the liquid storage assembly 1. The partition groove 41 is formed on the pressure-reducing assembly 2. When the pressure-reducing assembly 2 is inserted into the cup 131, the opening of the partition groove 41 is covered by the inner wall of the cup 131, so that the multiple first partitions 4, the outer wall of the pressure-reducing assembly 2, and the inner wall of the liquid storage cavity 11 (the inner wall of the cup 131) form a slow-flow channel 211.

[0080] In the above embodiment, the first separator 4 is an annular plate structure, so that the separator 41 formed by two adjacent first separators 4 is an annular through groove surrounding the pressure reducing component 2, so that the atomizing matrix in the slow flow channel 211 can be arranged around the periphery of the pressure reducing component 2.

[0081] Understandably, the first partition 4 of the annular plate structure has numerous virtual radial axes of symmetry passing through its center point. These radial axes of symmetry are set at an angle to the distribution directions of the confluence cavity 212 and the transition cavity 213, so that the flow direction of the atomized matrix in the partition groove 41 is at an angle to the distribution directions of the confluence cavity 212 and the transition cavity 213. This allows the first partition 4 to provide resistance to the atomized matrix flowing in the partition groove 41, thereby increasing the chance of the kinetic energy of the atomized matrix being consumed and further reducing the flow velocity of the atomized matrix.

[0082] Optionally, the aforementioned radial axis of symmetry is perpendicular to the distribution direction of the manifold 212 and the transition cavity 213.

[0083] In other embodiments, the first partition 4 is spirally extended and disposed on at least one of the inner wall of the liquid storage chamber 11 (the inner wall of the cup 131) and the outer wall of the pressure reducing assembly 2. The slow-flow channel 211 is formed by the first partition 4, the outer wall of the pressure reducing assembly 2 and the inner wall of the liquid storage chamber 11.

[0084] In the above embodiment, the slow-flow channel 211 formed by the first separator 4, the outer wall of the pressure reducing component 2 and the inner wall of the liquid storage cavity 11 is a channel that rotates and extends around the pressure reducing component 2 along the distribution direction of the confluence cavity 212 and the transition cavity 213.

[0085] Please refer to Figures 3 to 7In some embodiments, the liquid storage atomizing device further includes a second partition 5, which is disposed around at least one of the inner wall of the liquid storage chamber 11 (the inner wall of the cup 131) and the outer wall of the pressure reducing assembly 2, and the second partition 5 is spaced apart from the first partition 4. The manifold 212 is formed by the second partition 5, the first partition 4, the outer wall of the pressure reducing assembly 2, and the inner wall of the liquid storage chamber 11.

[0086] In the above embodiment, the second partition 5 is an annular plate structure, so that the manifold 212 formed by the second partition 5, the first partition 4, the outer wall of the pressure reducing component 2 and the inner wall of the liquid storage cavity 11 is an annular cavity surrounding the pressure reducing component 2, so that the atomizing matrix in the manifold 212 can be arranged around the periphery of the pressure reducing component 2.

[0087] Please refer to Figures 3 to 7 In some embodiments, the liquid storage atomizing device further includes a third partition 6, which surrounds at least one of the inner wall of the liquid storage chamber 11 (the inner wall of the cup 131) and the outer wall of the pressure reducing assembly 2. The third partition 6 is spaced apart from the first partition 4, and is located on the side of the first partition 4 away from the second partition 5.
