Description

Technical Field

[0001] This application relates to the field of aerosol heating and atomization technology, and in particular to an atomization component and an aerosol generating device. Background Technology

[0002] An aerosol generator is a low-pressure microelectronic atomization device that heats and atomizes a liquid aerosol generating matrix to produce a mist-like aerosol for users to inhale. To generate aerosols with various aroma types, the aerosol generator primarily employs a combination of multiple storage chambers: upper and lower chambers combined, or left and right chambers combined. Each chamber contains an atomizing core that atomizes the aerosol. In the upper and lower chamber structure, the aerosol atomized in the lower chamber is reheated by the atomizing core in the upper chamber, negatively impacting the taste. In the left and right chamber structure, the atomizing cores in the left and right chambers each have separate air passages, making it difficult for the generated aerosols to mix evenly at the mouthpiece, also negatively affecting the taste.

[0050] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0051] Please refer to the following: Figures 1 to 8 This application provides an aerosol generating device 1000, including an atomizing component 200. The aerosol generating device 1000 stores a sol-generating matrix. The aerosol generating matrix is ​​in a liquid state and can be adsorbed and heated by the atomizing component 200 to atomize and generate an aerosol for inhalation by a user. The atomizing component 200 can be installed in the liquid storage chamber 17 of the aerosol generating device 1000 to facilitate the adsorption of the liquid aerosol generating matrix stored in the liquid storage chamber 17.

[0052] The atomizing assembly 200 includes a fixed cylinder 2, at least two liquid guiding elements 32, and at least two heating elements 31. The fixed cylinder 2 is used to mount and fix the liquid guiding elements 32 and the heating elements 31; the liquid guiding elements 32 adsorb and guide the liquid aerosol generating matrix to the heating elements 31, and the heating elements 31 heat the liquid aerosol generating matrix to atomize and generate aerosol.

[0053] The fixed cylinder 2 has a hollow structure, and at least two liquid inlets 221 facing away from each other are provided at one end of the fixed cylinder 2, allowing liquid aerosol generating matrix outside the fixed cylinder 2 to enter the fixed cylinder 2 through the liquid inlets 221. At least two liquid guiding components 32 are housed in the fixed cylinder 2; the liquid guiding components 32 are arranged one-to-one with the liquid inlets 221, and each liquid guiding component 32 at least partially fills the corresponding liquid inlet 221, so that the liquid guiding component 32 located in the fixed cylinder 2 can adsorb the liquid aerosol generating matrix outside the fixed cylinder 2 through the part filled in the liquid inlet 221. At the same time, the liquid inlet 221 forms an installation and fixing effect on the liquid guiding component 32, improving the structural stability of the atomizing component 200.

[0054] At least two heating elements 31 are housed in the fixed cylinder 2; the heating elements 31 and the liquid guiding elements 32 are arranged in a one-to-one correspondence, and each heating element 31 is attached to the corresponding liquid guiding element 32 to heat the liquid aerosol generating matrix adsorbed and transferred through the liquid guiding element 32, and atomize to generate aerosol; wherein, all the liquid guiding elements 32 are separated from each other and spaced apart, so that the liquid aerosol generating matrix adsorbed by all the liquid guiding elements 32 will not be adsorbed and mixed at the liquid guiding element 32, so that each liquid guiding element 32 only supplies the aerosol generating matrix to the corresponding heating element 31, that is, the atomizing component 200 can simultaneously adsorb and heat to generate aerosols of different odor types for user use.

[0055] Since all the liquid guiding components 32 are installed in the same fixed cylinder 2, the heating element 31 corresponding to each liquid guiding component 32 is heated and atomized in the fixed cylinder 2 at the same time to generate aerosol. That is, aerosols of different odor types are mixed at the same time as they are generated, which effectively improves the uniformity of the mixing of aerosols of different odor types after they are output through the mouthpiece 7, and avoids the aerosol being repeatedly heated by the heating element 31, which effectively ensures the taste of the aerosol output through the mouthpiece 7 and improves the user experience.

[0056] The fixed cylinder 2 is provided with an airway confluence chamber 21 and at least two first chambers 22 and second chambers 23 disposed at the bottom of the airway confluence chamber 21 and arranged side by side at intervals. At least two liquid guiding components 32 can be respectively installed in the first chamber 22 and the second chamber 23, so that the liquid guiding components 32 are spaced apart and do not contact each other. At the same time, one end of all liquid guiding components 32 is exposed in the airway confluence chamber 21, so that the aerosol generated by atomization is directly mixed in the airway confluence chamber 21. The fixed cylinder 2 can be made of plastic, metal, or other materials. Manufacturers can choose different materials to make fixed cylinders 2 according to the actual needs.

[0057] The heating element 31 has a conductive pin 301, which protrudes from the end of the fixed cylinder 2 away from the liquid inlet 221. It is used to be soldered and fixed to the PCB board. The PCB board can control any one of the heating elements 31 to work individually or alternately, or the PCB board can control all the heating elements 31 to work simultaneously.

[0058] Please continue to refer to the following: Figures 3 to 8 In one embodiment, the atomizing component 200 has two liquid guiding elements 32 and two heating elements 31. One end of the fixed cylinder 2 is provided with two liquid inlets 221, and the two liquid inlets 221 are symmetrically distributed on both sides of the fixed cylinder 2, so that when the fixed cylinder 2 is installed in the aerosol generating device 1000, liquid enters from both sides, resulting in better balance.

[0059] The liquid inlets 221 on both sides correspond to different liquid storage chambers 17. Structurally, this facilitates the uniform distribution of the aerosol generation matrix. The spatial layout ensures the balance of liquid aerosol generation matrix adsorption by the liquid guiding component 32. This avoids situations where some liquid guiding components 32 adsorb too much or too little matrix due to uneven distribution of the liquid inlets 221. In turn, it ensures that each heating component 31 can stably and efficiently heat the corresponding type of aerosol generation matrix, ensuring a relatively balanced generation of aerosols of different odor types and improving the performance.

[0060] The atomizing assembly 200 may also have three liquid guiding elements 32 and three heating elements 31. The fixed cylinder 2 is correspondingly provided with an air passage confluence chamber 21 and three chambers 22, 23, and 25 arranged side by side and spaced apart at the bottom of the air passage confluence chamber 21. The three liquid guiding elements 32 can be installed in the first chamber 22, the second chamber 23, and the third chamber 25, respectively. The three liquid guiding elements 32 can be arranged in a triangular pattern or other distribution forms, and there is no specific limitation.

[0061] Please continue reading. Figure 3In one embodiment, the aerosol generating device 1000 further includes a liquid storage component 100. The liquid storage component 100 has at least two liquid storage chambers 17, all of which are isolated from each other. Each liquid storage chamber 17 is correspondingly and interconnected with a liquid inlet 221, allowing each chamber 17 to separately store different types of aerosol generating matrices, which are then provided to the atomizing component 200 to simultaneously generate aerosols of different odor types. The liquid storage component 100 has an air outlet 12. An air inlet 52 is connected to one end of the fixed cylinder 2 opposite to the liquid inlet 221, and an air outlet 12 is connected to the other end of the fixed cylinder 2 opposite to the air inlet 52. Outside air enters through the air inlet 52, passes through the fixed cylinder 2, mixes with the atomized aerosol, and is then discharged from the air outlet 12 for the user to inhale.

[0062] Please continue to refer to the following: Figure 3 and Figure 4 Furthermore, the liquid storage assembly 100 includes at least two liquid storage elements 11, each of which is correspondingly arranged with a liquid storage cavity 17. Each liquid storage element 11 is housed in a corresponding liquid storage cavity 17. Each liquid storage element 11 adsorbs and stores the aerosol generation matrix in the corresponding liquid storage cavity 17, thereby enhancing the independence of each liquid storage cavity 17. Each liquid storage element 11 can independently store a liquid aerosol generation matrix, which helps to maintain the stability of aerosol generation of different odor types.

[0063] Please continue to refer to the following: Figure 1 , Figure 3 and Figure 4 In one embodiment, the atomizing assembly 200 further includes a mounting base 5. The mounting base 5 is provided with an air inlet 52 that communicates with the fixed cylinder 2, through which outside air can enter the fixed cylinder 2.

[0064] There are two installation methods for the fixed base 5 and the fixed cylinder 2:

[0065] The first type is where the fixing seat 5 is at least partially inserted into the end of the fixing cylinder 2 away from the liquid inlet 221, and the fixing seat 5 abuts against the liquid guide 32; the fixing seat 5 can support and fix the liquid guide 32 on the one hand, preventing the liquid guide 32 from shaking in the fixing cylinder 2, and on the other hand, it can guide the airflow into the fixing cylinder 2 and make it evenly contact the liquid guide 32, assisting the atomization process of the liquid aerosol generating matrix.

[0066] The second method involves the fixing seat 5 being at least partially fitted onto the outer periphery of the end of the fixing cylinder 2 facing away from the liquid inlet 221, which also serves to fix and guide the airflow. Different installation methods for the fixing seat 5 and the fixing cylinder 2 can be selected according to the overall design requirements of the aerosol generating device 1000, providing diverse options for the installation of the atomizing component 200 and enhancing its adaptability. The fixing cylinder 2 and the fixing seat 5 can also be configured as an integrated structure.

[0067] Please refer to the following: Figure 1 , Figure 3 , Figure 4 and Figure 9 Furthermore, the liquid storage assembly 100 includes a cup body 1; the cup body 1 is composed of a top cover 14 and a cup cylinder 15 extending vertically from the edge of the top cover 14, the top cover 14 and the cup cylinder 15 forming a cup cavity 16. A fixing seat 5 is provided on the end of the cup cylinder 15 away from the top cover 14, an air inlet 52 is provided on the fixing seat 5, and an air outlet 12 is provided on the top cover 14.

[0068] The structural design of the cup body 1 and the fixed base 5 provides a closed and stable storage space. The fixed base 5 seals the bottom opening of the cup cavity 16, and the liquid aerosol generation matrix is ​​stored inside the cup cavity 16. The air inlet 52 is located on the fixed base 5 to facilitate the entry of outside air into the fixed cylinder 2, while the air outlet 12 is located on the top cover 14 to facilitate the discharge of the generated aerosol for the user to inhale. This structural design makes the aerosol generation device 1000 compact in overall structure, easy to manufacture and assemble.

[0069] A sealing plug 6 is also provided at the upper end of the cup body 1. The sealing plug 6 can be made of silicone. The sealing plug 6 has a first hole 61 corresponding to the positioning cylinder 10, and a suction nozzle 7 is also provided at the upper end of the sealing plug 6. The suction nozzle 7 and the sealing plug 6 can be a separate structure or an integrated structure. The sealing plug 6 also has a groove 62 that connects to the first hole 61. The groove 62 is filled with an adsorption element 63. The end of the suction nozzle 7 near the sealing plug 6 abuts against the adsorption element 63, and the suction nozzle 7 has a channel 71 for sequentially connecting the second hole 631 of the adsorption element 63, the first hole 61 of the sealing plug 6, and the positioning cylinder 10.

[0070] Please continue to refer to the following: Figure 3 , Figure 4 and Figure 9 In one embodiment, the cup body 1 further includes a positioning cylinder 10 and at least two partition plates 13. The positioning cylinder 10 is housed in the cup cavity 16 and is arranged around the air outlet 12. Each partition plate 13 is connected at both ends to the inner wall of the cup cylinder 15 and the outer wall of the positioning cylinder 10, respectively, to divide the cup cavity 16 into at least two liquid storage chambers 17. The end of the positioning cylinder 10 facing away from the top cover 14 is connected to the fixing cylinder 2. The positioning cylinder 10 helps to fix the partition plates 13, making the structure of the divided liquid storage chambers 17 more stable, and also guides the aerosol flow to the air outlet 12.

[0071] The partition plate 13 divides the cup cavity 16 into multiple liquid storage chambers 17, enabling separate storage of different types of liquid aerosol generation matrices. This further refines the function of the liquid storage component 100, providing a more reliable guarantee for the generation of diverse aerosols, and also optimizing the flow path of aerosols within the cup body 1. The lower opening of the positioning cylinder 10 is provided with a funnel-shaped guide port 101, into which the upper end of the air guide cylinder 24 is embedded, ensuring a stable assembly structure and convenient installation. This also allows aerosols passing through the air guide cylinder 24 to quickly enter the positioning cylinder 10.

[0072] Please continue to refer to the following: Figures 2 to 6 In another embodiment, the liquid guiding member 32 includes a gas guiding section 321 and a liquid suction section 322. The gas guiding section 321 is cylindrical, and the heating member 31 is attached to the corresponding gas guiding section 321, and the gas guiding section 321 is connected to the fixed cylinder 2. After the heating member 31 heats the liquid aerosol to generate a matrix, the aerosol is directly generated in the gas guiding section 321. The cylindrical structure of the gas guiding section 321 can effectively guide the airflow, allowing the aerosol to pass smoothly and flow in the fixed cylinder 2.

[0073] The liquid absorption section 322 extends from the outer periphery of the gas guide section 321 in a direction opposite to the gas guide section 321 and passes through the corresponding liquid inlet 221. The liquid absorption section 322 can contact the liquid aerosol generating matrix outside the fixed cylinder 2, adsorb and transport it to the gas guide section 321 through capillary action and other means, and then transfer it to the heating element 31 attached to the gas guide section 321. With the above structural design, the adsorption and transport efficiency of the liquid aerosol generating matrix is ​​improved, ensuring that the heating element 31 can obtain enough matrix for heating and atomization in a timely manner, thereby improving the atomization efficiency of the atomization assembly 200.

[0074] Please continue to refer to the following: Figure 3 and Figure 4 Furthermore, the atomizing assembly 200 is also provided with an air guide tube 24. The air guide tube 24 is at least partially housed in the fixed tube 2, and the end of the air guide tube 24 abuts against the liquid guide member 32 away from the fixed base 5, while the air guide tube 24 is connected to the fixed tube 2. The setting of the air guide tube 24 further optimizes the airflow path. When outside air enters the fixed tube 2 through the air inlet 52 of the fixed base 5, the air guide tube 24 can guide the airflow to fully mix with the generated different types of aerosols, which helps to improve the uniformity of different types of aerosols output through the nozzle 7 and improve the user experience.

[0075] Please continue to refer to the following: Figure 4 and Figure 9 In one embodiment, the fixing base 5 is provided with at least two sealing slots 51, and the cross-section of the sealing slots 51 may be U-shaped; the sealing slots 51 are provided corresponding to the partition plate 13, and the partition plate 13 is held in the corresponding sealing slots 51 to divide the cup cavity 16 into at least two liquid storage cavities 17.

[0076] The sealing latch 51 enhances the connection stability and sealing between the partition plate 13 and the fixing base 5, preventing leakage between liquid aerosol generating substrates in different storage chambers 17. This latching method facilitates the installation and disassembly of the fixing base 5 and the cup body 1, while ensuring effective isolation between the storage chambers 17. This allows the liquid storage assembly 100 to meet the storage and use requirements of different types of liquid aerosol generating substrates, further improving the reliability and practicality of the aerosol generating device 1000.

[0077] This application provides an atomizing component and an aerosol generating device. The atomizing component includes a fixed cylinder, at least two liquid guiding elements, and at least two heating elements. The at least two liquid guiding elements are housed in the fixed cylinder. All the liquid guiding elements are separated from each other and spaced apart, so that the liquid aerosol generating matrix adsorbed by all the liquid guiding elements will not be adsorbed and mixed at the liquid guiding elements. Since all the liquid guiding elements are installed in the same fixed cylinder, the heating element corresponding to each liquid guiding element is heated and atomized simultaneously in the fixed cylinder to generate aerosol. That is, aerosols of different odor types are mixed at the same time as they are generated, which effectively improves the uniformity of mixing of aerosols of different odor types after being output through the mouthpiece, and avoids the aerosol being repeatedly heated by the heating elements, effectively ensuring the taste of the aerosol output through the mouthpiece and improving the user experience.

[0078] Of course, the above description is only a specific embodiment of this application and is not intended to limit the scope of this application.
