Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically, to an atomizer and an aerosol generation device. Background Technology

[0002] An atomizer heats an aerosol-generating matrix to produce aerosol. The atomizer contains an outlet channel for transporting the aerosol, which exits the atomizer for the user. This outlet channel connects to a microphone, which is a sensor that detects the gas flow rate within the outlet channel. The environment in which the atomizer operates experiences temperature fluctuations (such as temperature differences between day and night). This can cause the gas in the atomizer's aerosol-generating matrix storage space to contract and absorb gas from the outside when the temperature decreases, and expand and force the aerosol-generating matrix into the outlet channel when the temperature increases. This can lead to clogging of the microphone in the aerosol generator. Utility Model Content

[0003] This application provides an atomizer and an aerosol generating device.

[0004] The atomizer according to this application includes a storage component, an atomizing tube, a heating element, and a first sealing element. The storage component has a loading cavity for loading an aerosol generation matrix. The atomizing tube is installed within the loading cavity and has an installation cavity communicating with the outside. The first sealing element is installed within the installation cavity and has accommodating cavities communicating with both the installation cavity and the loading cavity. The heating element has atomizing cavities extending through opposite ends of the heating element and is installed within the accommodating cavity. The atomizing cavities directly communicate with the installation cavity rather than directly with the loading cavity. A first channel, a first oil-retaining cavity, and a second channel are formed between the first sealing element and the atomizing tube. The first channel communicates with the outside through the installation cavity. The first oil-retaining cavity communicates with both the first channel and the second channel, and also communicates with the loading cavity through the second channel.

[0005] In some embodiments, the atomizing tube includes a first sub-section and a second sub-section connected to each other. The second sub-section is disposed on top of the first sub-section. The first sub-section has a first cavity, and the second sub-section has a second cavity. The first cavity and the second cavity communicate to form the mounting cavity. The peripheral wall of the first sub-section has a through hole that communicates with the loading cavity and the mounting cavity. The first sealing member includes a body portion and an extension portion. The body portion is housed in the first cavity and includes a side wall and a top wall. The second channel is disposed on the side wall of the body portion and / or the peripheral wall of the first sub-section. The extension portion is at least partially housed in the second cavity. The first channel is disposed on the peripheral wall of the second sub-section and / or the side wall of the extension portion. The top of the first sub-section, the peripheral wall of the first sub-section, the top wall of the body portion, and the side wall of the extension portion together form the first oil-containing cavity.

[0006] In some embodiments, the second channel is disposed on the side wall of the body portion. In the direction from the body portion to the extension portion, the second channel extends spirally or linearly.

[0007] In some embodiments, the cross-section of the second channel, obtained by a plane perpendicular to the direction of extension of the second channel, is circular or a portion of a circle. The diameter of the circle is greater than or equal to 1 mm and less than or equal to 3 mm.

[0008] In some embodiments, the first channel is disposed on the sidewall of the extension and extends in a straight line in the direction from the body to the extension.

[0009] In some embodiments, the area of ​​the cross-section of the first channel cut by a plane perpendicular to the axial direction of the atomizer is greater than the area of ​​the cross-section of the second channel cut by a plane perpendicular to the extension direction of the second channel.

[0010] In some embodiments, the sidewalls of the extension are provided with a plurality of the first channels, which are distributed at intervals around the center of the extension.

[0011] In some embodiments, the atomizer further includes a second seal, with the first seal and the second seal disposed at opposite ends of the heating element; the second seal is located between the heating element and the atomizing tube; a third channel, a second oil-retaining chamber, and a fourth channel are formed between the second seal and the atomizing tube, the third channel being connected to the outside, the second oil-retaining chamber being connected to the third channel and the fourth channel, and being connected to the loading chamber through the fourth channel.

[0012] In some embodiments, the heating element has a feed surface on its radially outer surface of the atomizing chamber, the feed surface being exposed to the loading chamber. The atomizing tube has a mist outlet direction, and the aerosol generated by the heating element is output to the outside along the mist outlet direction. The feed surface, the second channel, the first oil storage chamber, and the first channel are arranged sequentially from downstream to upstream in the mist outlet direction.

[0013] The aerosol generating apparatus of this application includes the atomizer and power supply component described in any of the above embodiments, wherein the power supply component is electrically connected to the atomizer.

[0014] In the atomizer and aerosol generating device of this application, the loading chamber in the storage component is used to load the aerosol generating matrix. The heating element is disposed in the mounting chamber of the atomizing tube, and the atomizing chamber of the heating element is connected to the loading chamber through the mounting chamber. In this way, the heating element can absorb the aerosol generating matrix in the loading chamber and atomize it before delivering it to the atomizing chamber to form an aerosol. A first channel, a first oil-retaining chamber, and a second channel are formed between the first sealing element and the atomizing tube. When the gas volume change in the loading chamber is too large and tends to squeeze the aerosol generating matrix towards the heating element, since the first channel is connected to the outside, the gas pressure in the first oil-retaining chamber is also the external atmospheric pressure. The second channel allows the aerosol generating matrix to preferentially enter the first oil-retaining chamber, rather than breaking through the heating element and entering the atomizing chamber, thus preventing leakage of the aerosol generating matrix. It can be seen that the embodiment of this application can avoid the aerosol generating matrix from entering the atomizing chamber and leaking, and therefore will not enter the atomizer's mist outlet channel and clog the microphone.

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] The atomizer contains an aerosol-generating matrix and a heating element. One side of the heating element absorbs the aerosol-generating matrix, generating heat to atomize it. The other side of the heating element expels the atomized aerosol-generating matrix, forming an aerosol. The aerosol is then transported out of the atomizer for user use. Because the heating element has the ability to absorb the aerosol-generating matrix, the matrix naturally possesses a certain degree of flowability within the heating element. Therefore, if the aerosol-generating matrix is ​​compressed towards the heating element, it can pass through it.

[0043] The loading chamber in the atomizer, which is used to load the aerosol generating matrix, does not contain only the aerosol generating matrix. This is because the aerosol generating matrix is ​​continuously atomized and consumed during the aerosol generation process. After the aerosol generating matrix is ​​consumed, there will be empty space in the loading chamber, which will create a negative pressure. This will force the ambient atmosphere into the loading chamber (for example, by passing through the heating element into the loading chamber).

[0044] When there is a large amount of gas in the loading chamber (resulting in a significant consumption of the aerosol generating matrix), the volume change of the gas during heating and precooling is substantial. Thus, when the atomizer is in a low-temperature environment (e.g., at night), the gas in the loading chamber contracts during precooling, causing a drop in pressure. This results in more gas entering the loading chamber to maintain pressure balance between the loading chamber and the external environment. Conversely, when the atomizer enters a high-temperature environment (e.g., during the day), the gas in the loading chamber expands during preheating, causing a rise in pressure. This necessitates the discharge of a larger volume of contents from the loading chamber to maintain pressure balance. However, since the loading chamber contains both gaseous and liquid aerosol generating matrix, the gas may push the aerosol generating matrix towards the heating element, causing it to leak through the heating element.

[0045] Aerosol generating matrices often have high viscosity (e.g., aerosol generating matrices can be liquids like sesame oil) and may solidify due to low temperatures or denaturation. Therefore, leaking aerosol generating matrices can clog the aerosol output channels, hindering aerosol output, or prevent the microphone from starting, leading to malfunction of the aerosol generating device. To avoid malfunctions, a more leak-proof atomizer is needed.

[0046] This application provides an atomizer 100 and an aerosol generating device 1000. Please refer to... Figure 1The aerosol generating device 1000 provided in this application includes an atomizer 100 and a power supply component 200. The power supply component 200 is a component for outputting electrical energy. For example, the power supply component 200 may be equipped with a battery to provide electrical energy. The power supply component 200 may also be a component equipped with a transformer and / or rectifier, so that the power supply component 200 can be connected to mains power and convert the mains power into a form usable by the atomizer 100 to provide electrical energy to the atomizer 100. Of course, the power supply component 200 may also be provided with a housing, i.e., as... Figure 1 In the illustrated embodiment, the housing of the power supply assembly 200 is connected to the atomizer 100, thereby connecting the atomizer 100 to the power supply assembly 200. Please refer to the following: Figure 1 and Figure 2 The atomizer 100 and the power supply component 200 can be screwed together by studs on the mounting base 61. The atomizer 100 and the power supply component 200 can also be connected by snap-fit, magnetic attraction or interference fit. In addition, the atomizer 100 and the power supply component 200 are also electrically connected, so that the electrical energy provided by the power supply component 200 can be received and utilized by the atomizer 100.

[0047] Atomizer 100 is a device that stores an aerosol generating matrix and generates aerosol by heating the aerosol generating matrix. The aerosol can be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol generating matrix is ​​a processed product that can generate aerosol upon heating. The aerosol generating matrix can be in a liquid state, or in a fully solid or semi-solid state. When the aerosol generating matrix is ​​liquid, it is a mixed liquid containing dissolved substances such as nicotine and alkaloids, with solutes such as propylene glycol, vegetable glycerin, and pure water, and / or inorganic solutes. When the aerosol generating matrix is ​​fully solid, it can be prepared using processes such as rolling, slurry preparation, die casting, or extrusion. In this application, the aerosol generating matrix can be a high-viscosity e-liquid (e.g., sesame oil), which can generate aerosol upon heating.

[0048] The heating method for the atomizer 100 to heat the aerosol generating matrix can be, but is not limited to, resistance heating, microwave heating, or laser irradiation heating. In this embodiment, the atomizer 100 is provided with a heating element 30, which is a resistance heating element. The main body of the heating element 30 can be made of porous ceramic material or other porous materials (such as glass fiber cotton or organic cotton). Porous ceramics are usually prepared by mixing ceramic slurry with a pore-forming agent and then injection molding and sintering. The sintered ceramic body has a large number of micropores. In this way, when the aerosol generating matrix comes into contact with the heating element 30, it can enter the heating element 30 under capillary action. The heating element 30 is provided with a heating wire. When the heating wire is energized, it generates a thermal effect, thereby heating and atomizing the aerosol generating matrix that has entered the heating element 30, and finally forming an aerosol in the atomization chamber 31. The aerosol is finally delivered out of the atomizer 100 for the user to use. Please refer to the following: Figure 5 and Figure 6 ,exist Figure 5 In the illustrated embodiment, the aerosol is formed in the atomizing chamber 31 and sequentially passes through the air passage in the extension 42 of the first seal 40, the air passage in the second sub-section 22 of the atomizing tube 20, and the air passage in the mouthpiece 80 before exiting the atomizer 100. The user can inhale through the mouthpiece 80, providing delivery force to the aerosol and transporting it out of the atomizer 100 for the user's use. In other embodiments, the aerosol can directly enter the air passage in the mouthpiece 80 and exit the atomizer 100, or it can pass through the first seal 40 before exiting the atomizer 100. In other embodiments, conductors may also be provided in the heating element 30, and the atomizer 100 may include a magnetic field generating device. The magnetic field generating device generates a changing magnetic field that acts on the conductors, causing eddy currents to be generated inside the conductors, thus heating the aerosol generation matrix that enters the heating element 30.

[0049] It is understood that the aerosol generating device 1000 provided in the embodiments of this application includes the atomizer 100 provided in the embodiments of this application. Therefore, the beneficial effects of the aerosol generating device 1000 provided in the embodiments of this application are the same as the beneficial effects of the atomizer 100 provided in the embodiments of this application mentioned below. Please refer to the following text.

[0050] Please refer to Figure 3 and Figure 6 The atomizer 100 according to this application includes a storage member 10, an atomizing tube 20, a heating element 30, and a first sealing member 40. Please refer to the reference. Figure 5The storage unit 10 is provided with a loading cavity 11 for loading the aerosol generation matrix. An atomizing tube 20 is installed within the loading cavity 11, and the atomizing tube 20 has an installation cavity 201 communicating with the outside. A first sealing member 40 is installed within the installation cavity 201 and has a receiving cavity 43 communicating with both the installation cavity 201 and the loading cavity 11. The heating element 30 has an atomizing cavity 31 extending through opposite ends of the heating element 30 and is installed within the receiving cavity 43. The atomizing cavity 31 is directly connected to the installation cavity 201 rather than directly connected to the loading cavity 11. A first channel 51, a first oil-retaining cavity 52, and a second channel 53 are formed between the first sealing member 40 and the atomizing tube 20. The first channel 51 communicates with the outside through the installation cavity 201, and the first oil-retaining cavity 52 connects the first channel 51 and the second channel 53, and is also connected to the loading cavity 11 through the second channel 53.

[0051] Storage device 10 is a device for storing the aerosol generation matrix. Figure 5 In the illustrated embodiment, the storage component 10 also forms part of the housing of the atomizer 100. However, in other embodiments, the housing of the atomizer 100 can be provided separately, while the storage component 10 is disposed within the housing. The loading chamber 11 in the storage component 10 can hold the aerosol generation matrix, and the atomizing tube 20 can be installed within the loading chamber 11. The atomizing tube 20 is a conduit for mounting the heating element 30 and conveying the aerosol generated by the heating element 30. The atomizing tube 20 has a mounting cavity 201, in which the first sealing member 40 is installed, and the heating element 30 is installed within a receiving cavity 43 formed by the first sealing member 40. The receiving cavity 43 communicates with both the loading chamber 11 and the mounting cavity 201, thus allowing the heating element 30 to communicate with the loading chamber 11 through the mounting cavity 201. Furthermore, since the atomizing tube 20 is disposed within the loading chamber 11, the atomizing cavity 31 in the heating element 30 can be indirectly connected to the loading chamber 11 through the heating element 30. Indirect connection refers to a connection that is not achieved through air connection, but rather through a porous heating element 30 spaced between the loading cavity 11 and the atomizing cavity 31, thus achieving liquid-conducting connection. For example... Figure 6In the illustrated embodiment, the mounting cavity 201 is directly connected to the loading cavity 11 through a through hole 213 on the atomizing tube 20, thereby allowing the atomizing cavity 31 to be indirectly connected to the loading cavity 11. It should be noted that the heating element 30 is made of a porous material; therefore, as long as the outer surface of the heating element 30 is exposed to the loading cavity 11, the atomizing cavity 31 and the loading cavity 11 can be indirectly connected. The first seal 40 is a component used to prevent the aerosol generating matrix from leaking from the mating gap between the heating element 30 and the atomizing tube 20. The first seal 40 is located between the heating element 30 and the atomizing tube 20, ensuring that the aerosol generating matrix can only enter the atomizing cavity 31 through the heating element 30. Thus, the aerosol generating matrix is ​​only output outside the atomizer 100 after forming an aerosol. If the aerosol generating matrix leaks into the atomizing cavity 31 from the mating gap between the heating element 30 and the atomizing tube 20, the aerosol generating matrix may clog the atomizing cavity 31. Furthermore, the atomizing chamber 31 extends through both ends of the heating element 30, allowing gas to enter one end of the atomizing chamber 31 and mix with the atomized aerosol generating matrix to form an aerosol; the other end of the atomizing chamber 31 can transport the generated aerosol out of the atomizer 100. Therefore, the air inlet of the atomizing chamber 31 faces the power supply component 200, meaning that leaked aerosol generating matrix may flow onto structures such as the power supply component 200, damaging the aerosol generating device 1000. Therefore, the first sealing element 40 provides a sealing effect for the aerosol generating matrix. The first oil-containing chamber 52 is a space for containing the aerosol generating matrix. The first channel 51 connects to both the outside and the first oil-containing chamber 52, ensuring that the air pressure inside the first oil-containing chamber 52 is the same as the outside pressure. The second channel 53 connects the first oil-containing chamber 52 to the loading chamber 11, allowing the aerosol generating matrix in the loading chamber 11 to enter the first oil-containing chamber 52 through the second channel 53. The first oil-containing cavity 52 can be formed inside the first sealing element 40, or inside the atomizing tube 20, or as... Figure 6 The diagram shows a structure formed by the atomizing tube 20 and the first sealing element 40. The first channel 51 and the second channel 53 can be formed inside or outside the first sealing element 40, or inside or outside the atomizing tube 20, or formed by the atomizing tube 20 and the first sealing element 40. That is to say, the first sealing element 40 and the atomizing tube 20 form the first channel 51, the first oil-containing cavity 52, and the second channel 53.

[0052] When the gas pressure in the loading chamber 11 is high, and some substances in the loading chamber 11 need to be expelled to balance with the external air pressure, the aerosol generating matrix may tend to be expelled to the outside under the pushing force of the gas in the loading chamber 11. Since the first channel 51 makes the air pressure in the first oil-filling chamber 52 equal to the external air pressure, when the air pressure in the loading chamber 11 is greater than the external air pressure, it is also greater than the air pressure in the first oil-filling chamber 52. Therefore, in this embodiment, the aerosol generating matrix can enter the first oil-filling chamber 52 through the second channel 53 without breaking through the restriction of the heating element 30 to enter the atomizing chamber 31. The atomizing chamber 31 is connected to the microphone of the atomizer, so the aerosol generating matrix will not leak and clog the microphone.

[0053] Furthermore, it is understandable that the first oil reservoir 52, the second channel 53, and the loading chamber 11 can form a communicating vessel structure, thus achieving pressure differential balance or liquid level equilibrium between the first oil reservoir 52 and the loading chamber 11. When a large amount of aerosol generation matrix is ​​consumed in the loading chamber 11, or when a negative pressure is generated due to temperature drop, the aerosol generation matrix in the first oil reservoir 52 can be drawn back into the loading chamber 11, preventing waste.

[0054] Please refer to Figure 7 In some embodiments, the atomizing tube 20 includes a first sub-section 21 and a second sub-section 22 connected together. (Please refer to...) Figure 6 The second sub-part 22 is disposed on the top 211 of the first sub-part. The first sub-part 21 has a first cavity 214, and the second sub-part 22 has a second cavity 221. The first cavity 214 and the second cavity 221 communicate to form the mounting cavity 201. The peripheral wall 212 of the first sub-part has a through hole 213, which communicates with the loading cavity 11 and the mounting cavity 201. The first sealing member 40 includes a body part 41 and an extension part 42. The body part 41 is housed in the first cavity 214 and includes a side wall and a top wall. A second channel 53 is disposed on the side wall 412 of the body part and / or the peripheral wall 212 of the first sub-part. The extension part 42 is at least partially housed in the second cavity 221. The first channel 51 is disposed on the peripheral wall of the second sub-part 22 and / or the side wall 421 of the extension part. The top 211 of the first sub-part, the peripheral wall 212 of the first sub-part, the top wall 411 of the body part, and the side wall 421 of the extension part together form the first oil storage cavity 52.

[0055] The first sub-section 21 and the second sub-section 22 are two axial parts of the atomizing tube 20. The first sub-section 21 mainly accommodates the heating element 30, while the second sub-section 22 mainly transports the aerosol. The aerosol is primarily transported to the outside through the second sub-section 22. The aerosol transport direction is the mist exit direction (the direction in which the aerosol is transported out of the atomizer 100). The top 211 of the first sub-section is the top of the first sub-section 21 in the mist exit direction. The first sub-section 21 can accommodate the heating element 30, so the through hole 213 on the first sub-section 21 allows the heating element 30 to be exposed to the loading cavity 11, thereby absorbing the aerosol to generate the matrix. The peripheral wall 212 of the first sub-section is the wall that mates with the first sub-section 21. The body part 41 of the first seal 40 is the part of the first seal 40 that mates with the first sub-section 21, and the extension part 42 is the part of the first seal 40 that mates with the second sub-section 22. The top wall 411 of the main body is the wall where the main body 41 meets the extension 42 (the top wall in the mist exit direction). The side wall 421 of the extension is the wall where the extension 42 mates with the second sub-part 22. The second channel 53 being located on the side wall 412 of the main body means that the second channel 53 is a channel formed in the main body 41. In one example, the second channel 53 is located on the outside of the side wall 412 of the main body, such as... Figure 4As shown; in another example, the second channel 53 is disposed inside the side wall 412 of the main body, that is, between the inner and outer sides of the side wall 412 of the main body. In this case, the second channel 53 may not contact the first sub-part 21. The second channel 53 being disposed on the peripheral wall 212 of the first sub-part means that the second channel 53 is a channel formed in the first sub-part 21. In one example, the second channel 53 is disposed inside the peripheral wall 212 of the first sub-part, that is, between the inner and outer sides of the peripheral wall 212 of the first sub-part. In this case, the second channel 53 may not contact the main body 41. In another example, the second channel 53 is disposed on the inner side of the peripheral wall 212 of the first sub-part, that is, on the side of the peripheral wall 212 of the first sub-part facing the main body 41. In this case, the second channel 53 may contact the main body 41. The second channel 53 is provided on the side wall 412 of the main body and the peripheral wall 212 of the first sub-part, meaning that the main body 41 and the first sub-part 21 are at least partially spaced to form the second channel 53, or the second channel 53 is simultaneously opened in the main body 41 and the first sub-part 21 (i.e., the second channel 53 will pass through the main body 41 and the first sub-part 21 during its extension). The first channel 51 is provided on the peripheral wall of the second sub-part 22, meaning that the first channel 51 is a channel opened in the second sub-part 22. In one example, the first channel 51 is provided inside the peripheral wall of the second sub-part 22, that is, between the inner and outer sides of the peripheral wall of the second sub-part 22. In this case, the first channel 51 may not contact the extension 42. In another example, the first channel 51 is provided inside the peripheral wall of the second sub-part 22. In this case, the first channel 51 may contact the extension 42. The first channel 51 is disposed on the side wall 421 of the extension portion, meaning that the first channel 51 is a channel formed in the extension portion 42. In one example, the first channel 51 is disposed inside the side wall 421 of the extension portion, that is, between the inner and outer sides of the side wall 421 of the extension portion. In this case, the first channel 51 may not contact the second sub-part 22. In another example, the first channel 51 is disposed on the outer side of the side wall 421 of the extension portion, such as... Figure 4 and Figure 6 As shown, the first channel 51 can contact the second sub-part 22 at this time. The first channel 51 is provided on the peripheral wall of the second sub-part 22 and the side wall 421 of the extension, which means that the second sub-part 22 and the extension 42 are at least partially spaced to form the first channel 51, or the first channel 51 is opened in both the second sub-part 22 and the extension 42 (that is, during the extension of the first channel 51, it will pass through the extension 42 and the second sub-part 22).

[0056] The top 211 of the first sub-part, the peripheral wall 212 of the first sub-part, the top wall 411 of the main body, and the side wall 421 of the extension together form the first oil storage cavity 52. ​​It can be seen that the first oil storage cavity 52 configured in this way does not require additional new structures to be set on the atomizing tube 20 or the first sealing member 40 to form the first oil storage cavity 52 (for example, hollowing out a part in the first sealing member 40 to form the first oil storage cavity 52), which makes the formation of the first oil storage cavity 52 simpler and reduces the production cost of the atomizer 100.

[0057] In some embodiments, the second channel 53 is disposed on the side wall 412 of the body portion. The second channel 53 extends spirally in the direction from the body portion 41 to the extension portion 42. Figure 4 (As shown) or extends in a straight line.

[0058] exist Figure 4 In the embodiment shown, the second channel 53 extends spirally in the direction from the main body 41 to the extension 42, that is, in the extension direction (or axial direction) of the extension 42. Figure 4 The extension state of the second channel 53. In this embodiment, the second channel 53 can rotate around the body portion 41 any number of times, such as 0.5 rotations, 1 rotation, 1.5 rotations, or 2 rotations. The second channel 53 extends in a straight line, that is, it extends along the axial direction of the extension portion 42.

[0059] Please refer to the reference. Figure 6 The spiral extension of the second channel 53 prevents the aerosol generating matrix from directly impacting the second channel 53 (e.g., when the user shakes the atomizer 100). This means that even if the atomizer 100 experiences severe shaking (such as the atomizer 100 falling, the user shaking the atomizer 100, or the atomizer 100 being in a bumpy vehicle), the aerosol generating matrix entering the second channel 53 will lose kinetic energy during its transmission within the second channel 53, preventing it from flooding into the first oil-containing chamber 52 and further leaking through the first channel 51. Therefore, the spiral extension of the second channel 53 improves the sealing effect of the atomizer 100. Conversely, a straight extension of the second channel 53 helps reduce the manufacturing difficulty of the second channel 53, thus reducing the production cost of the first sealing element 40.

[0060] Please refer to Figure 4 and Figure 6 In some embodiments, the cross-section of the second channel 53 obtained by a plane perpendicular to the extension direction of the second channel 53 is circular or a portion of a circle. The diameter of the circle is greater than or equal to 1 mm and less than or equal to 3 mm.

[0061] When the cross-section of the second channel 53, obtained by a plane perpendicular to its extending direction, is circular, it is equivalent to the second channel 53 being disposed within the first seal 40. When the cross-section of the second channel 53, obtained by a plane perpendicular to its extending direction, is a portion of a circle, it is equivalent to the second channel 53 being disposed on the surface of the first seal 40, or equivalent to the first seal 40 and the atomizing tube 20 being at least partially spaced to form the second channel 53. Figure 6 As shown in the cross-section, the section formed by the second channel 53 cut by a plane perpendicular to the extension direction of the second channel 53 can be semi-circular, that is, a portion of a circle. This is understandable. Figure 6 The cross-section shown is not strictly perpendicular to the extension direction of the second channel 53, but because Figure 6 In the embodiment shown, the centerline of the second channel 53 is equivalent to a helix, and the pitch of the helix intersects the diameter of the helix, so the cross-section passing through the central axis of the helix ( Figure 6 The cross section shown is approximately considered to be a cross section perpendicular to the extension direction of the second channel 53. Furthermore, for ease of description, the cross section obtained by the second channel 53 being cut by a plane perpendicular to the extension direction of the second channel 53 will be referred to simply as a cross section.

[0062] When the aerosol generating matrix passes through the channel, it encounters resistance. This resistance may be due to the convex liquid surface formed by the aerosol generating matrix within the channel, creating a pressure difference on both sides of the convex liquid surface. According to the principles of fluid mechanics, the greater the curvature of the liquid surface, the greater the pressure difference, and thus the greater the resistance of this pressure difference to the aerosol generating matrix. Therefore, the larger the radius of curvature formed by the aerosol generating matrix as it passes through the channel, the smaller the resistance. The cross-section of the second channel 53 is circular or a portion of a circle. If the diameter of the cross-section of the second channel 53 is less than 1 mm, it may result in an excessively small portion on the cross-section of the second channel 53, causing a large radius of curvature of the liquid surface. In this case, the second channel 53 will have a greater obstructive effect on the aerosol generating matrix, which may cause the aerosol generating matrix, under the pressure of the air in the loading cavity 11, to not enter the first oil storage cavity 52 through the second channel 53, but instead break through the heating element 30 and enter the atomization cavity 31, leading to leakage of the aerosol generating matrix. If the diameter of the cross-section of the second channel 53 is greater than 3 mm, it may result in an excessively large cross-sectional size, leading to a small radius of curvature of the liquid surface. This would reduce the obstruction of the aerosol generation matrix by the second channel 53, allowing it to flow freely and causing leakage. Therefore, the cross-section of the second channel 53 is circular or a portion thereof, with a diameter greater than or equal to 1 mm and less than or equal to 3 mm. This effectively overcomes the aforementioned problem, ensuring that the obstruction of the aerosol generation matrix by the second channel 53 is appropriate. It prevents the aerosol generation matrix from breaking through the heating element 30 and entering the atomization chamber 31, thus preventing leakage, and also prevents it from freely entering the oil reservoir 52, which would lead to leakage (or cause the oil reservoir 52 to constantly store a large amount of aerosol generation matrix, thus failing to achieve pressure balance).

[0063] Please refer to Figure 4 In some embodiments, the first channel 51 is provided on the side wall 421 of the extension portion, and the first channel 51 extends in a straight line in the direction from the main body portion 41 to the extension portion 42.

[0064] exist Figure 4 In the embodiment shown, this is also equivalent to the first channel 51 extending axially along the extension 42, or extending axially along the atomizing tube 20.

[0065] Please refer to this as well. Figure 6 It can be seen that in Figure 6In the illustrated embodiment, the first channel 51 connects to the outside world through an air passage in the second sub-section 22 of the atomizing tube 20 (the air passage in the second sub-section 22 connects to the outside world through an air passage in the nozzle 80). Therefore, when the first channel 51 extends axially along the extension 42, it can connect to the outside world in the shortest distance, thereby reducing the length of the first channel 51 and reducing the resistance of the first channel 51 to the gas. Since the first channel 51 mainly vents to the atmosphere, the gas pressure in the first oil reservoir 52 is balanced with the atmospheric pressure. Therefore, extending the first channel 51 axially along the extension 42 can increase the gas flow rate of the first channel 51 and improve the gas pressure balancing effect on the first oil reservoir 52.

[0066] In some embodiments, the area of ​​the cross section of the first channel 51 cut by a plane perpendicular to the axial direction of the atomizer 100 is greater than the area of ​​the cross section of the second channel 53 cut by a plane perpendicular to the extension direction of the second channel 53.

[0067] The plane perpendicular to the axial direction of the atomizer 100 corresponds to the axial section of the vertical extension 42, and also to the cross-section of the first channel 51. The meaning of the plane perpendicular to the extension direction of the second channel 53 can be found above.

[0068] The cross-sectional area of ​​the first channel 51, which is cut by a plane perpendicular to the axial direction of the atomizer 100, is larger than the cross-sectional area of ​​the second channel 53, which is cut by a plane perpendicular to the extension direction of the second channel 53. This allows the resistance of the aerosol generating matrix through the first channel 51 to be greater than the resistance through the second channel 53 (the specific principle can also be found above). In this way, the aerosol generating matrix can easily enter the first oil-containing cavity 52, but is less likely to leak through the first channel 51, thus improving the sealing effect of the atomizer 100.

[0069] Please refer to Figure 4 In some embodiments, the sidewall 421 of the extension is provided with a plurality of first channels 51, which are distributed at intervals around the center of the extension 42.

[0070] This is equivalent to multiple first channels 51 being distributed at intervals in the circumferential direction of the extension 42. The multiple first channels 51 can be distributed at equal or unequal intervals.

[0071] The arrangement of multiple first channels 51 is equivalent to setting up multiple balancing channels for the first oil storage chamber 52, allowing atmospheric pressure to balance with the air pressure in the first oil storage chamber 52. Since there is an aerosol generating matrix in the first oil storage chamber 52, the end of the first channel 51 facing the first oil storage chamber 52 may be blocked by the aerosol generating matrix. However, the arrangement of multiple first channels 51 ensures that even if some first channels 51 are blocked, there are still remaining first channels 51 that can complete the function of balancing air pressure. Therefore, the oil storage function of the first oil storage chamber 52 can be guaranteed, and the sealing effect of the atomizer 100 can be improved.

[0072] Please refer to Figure 5 In some embodiments, the atomizer further includes a second seal 72, with the first seal 40 and the second seal 72 respectively disposed at both ends of the heating element 30. The second seal 72 is located between the heating element 30 and the atomizing tube 20. A third channel, a second oil-retaining chamber, and a fourth channel are formed between the second seal 72 and the atomizing tube 20. The third channel communicates with the outside, and the second oil-retaining chamber communicates with the third channel and the fourth channel, and is also connected to the loading chamber through the fourth channel.

[0073] The second seal 72, like the first seal 40, is also located between the heating element 30 and the atomizing tube 20, preventing the aerosol generation matrix from leaking out from the mating gap between the heating element 30 and the atomizing tube 20. The structure of the third channel can refer to all embodiments provided for the first channel 51 in this application, and the structure of the fourth channel can refer to all embodiments provided for the second channel 53 in this application. Furthermore, the third channel can communicate with the outside world through the fifth channel; the feed surface 32, the fourth channel, the second oil reservoir, and the third channel can be arranged sequentially from downstream to upstream in the mist outlet direction.

[0074] Since the second seal 72 functions similarly to the first seal 40, and the third channel, fourth channel, and second oil reservoir can serve the same function as the first channel 51, second channel 53, and first oil reservoir 52, they all have the same beneficial effects. Furthermore, the third channel, fourth channel, and second oil reservoir can be combined with the first channel 51, second channel 53, and first oil reservoir 52 to further improve the sealing effect of the atomizer 100.

[0075] Please refer to Figure 6 In some embodiments, the heating element 30 has a feed surface 32 on its radially outer surface along the atomizing chamber 31, and the feed surface 32 is exposed to the loading chamber 11. The atomizing tube 20 has a mist outlet direction, and the aerosol generated by the heating element 30 is output to the outside along the mist outlet direction. The feed surface 32, the second channel 53, the first oil storage chamber 52, and the first channel 51 are arranged sequentially from downstream to upstream in the mist outlet direction.

[0076] The feed surface 32, i.e., on the heating element 30, is the surface through which the aerosol generation matrix first passes before entering the heating element 30. The mist outlet direction of the atomizing tube 20 is... Figure 5 In the illustrated embodiment, the direction from the atomizing tube 20 to the nozzle 80 is essentially the direction of aerosol transport within the atomizing tube 20.

[0077] When using the aerosol generator 1000, it is typically positioned upright, meaning the mist output direction is often against gravity. In this configuration, the feed surface 32, the first channel 51, the first oil reservoir 52, and the second channel 53 are arranged sequentially from downstream to upstream in the mist output direction, ensuring they are aligned from low to high in the direction of gravity. This arrangement ensures that the aerosol generating matrix in the first oil reservoir 52 settles at the bottom, making it difficult for the user to extract it through the first channel 51. Furthermore, when the aerosol generating matrix in the loading chamber 11 is depleted, it can flow towards the feed surface 32 under gravity, preventing waste. It is evident that the feed surface 32, the first channel 51, the first oil storage chamber 52, and the second channel 53 are arranged sequentially from downstream to upstream in the mist output direction, which can improve the sealing effect of the atomizer 100 and the utilization rate of the aerosol generation matrix.

[0078] Please refer to Figure 3 and Figure 5 In some embodiments, the atomizer 100 further includes a conductive mounting base 61 and a bracket 62, with the bracket 62 installed within the mounting base 61. The storage element 10 and the first sub-part 21 are both connected to the mounting base 61. The atomizer 100 also includes an electrical connector 63. A second seal 72 is located between the heating element 30 and the bracket 62. The electrical connector 63 is installed within the mounting base 61 via an insulated fastener 64. The mounting base 61 is connected to one electrode of the heating element 30, and the electrical connector 63 is connected to the other electrode of the heating element 30. The electrical connector 63 has a fifth channel 631 extending through both opposite ends, and the fifth channel 631 communicates with the atomization chamber 31.

[0079] Mounting base 61 is the part that connects the atomizer 100 and the power supply component 200. Threaded posts can be provided on mounting base 61, which are screwed onto the power supply component 200. Bracket 62 supports the second seal 72 axially on the atomizer 100, thereby limiting the relative positional relationship between the second seal 72 and mounting base 61, and further serving to support the heating element 30. The fixing member 64 serves two purposes: firstly, it allows the electrical connector 63 to be mounted on the mounting base 61, and secondly, it insulates the electrical connector 63 from the mounting base 61. When the heating element 30 contains a heating wire, the fixing member 64 can also have holes drilled inside for the positive and negative terminals of the heating wire in the heating element 30 to be routed. For example, the positive terminal of the heating wire can be connected to the fixing member, and the negative terminal of the heating wire can be connected to the mounting base 61. In this way, when the mounting base 61 is connected to the power supply assembly 200, the electrical connector 63 is connected to the positive terminal of the power supply assembly 200, and the mounting base 61 is connected to the negative terminal of the power supply assembly 200, thereby completing the power supply to the heating wire. Electrical connector 63 can also serve as a ventilation device. Since the aerosol in the atomizing chamber 31 of the heating element 30 needs to be transported out of the atomizing chamber 31 by airflow, one end of the atomizing chamber 31 can be connected to the fifth channel 631. When the user creates negative pressure at the end of the atomizing chamber 31 away from the fifth channel 631 (for example, by inhaling through the mouthpiece 80), the fifth channel 631 can be connected to the outside, thereby replenishing the atomizing chamber 31 with gas, forming an airflow, and allowing the aerosol in the atomizing chamber 31 to be transported out of the atomizer 100.

[0080] Please refer to Figure 3 In some embodiments, the atomizer 100 may further include a third seal 73, a first retaining ring 91, and a second retaining ring 92. Please refer to the references. Figure 5 The third seal 73 is used to close the end of the storage component facing the nozzle, forming a sealed loading cavity 11. The first retaining ring 91 is used to secure the nozzle 80 and the storage component 10, and the second retaining ring 92 is used to secure the storage component 10 and the mounting base 61. Both the first retaining ring 91 and the second retaining ring 92 can be decorative metal rings.

[0081] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.
