Description

Technical Field

[0001] The present invention relates to the field of atomization technology, in particular to an atomization device and an aerosol generating equipment. Background Art

[0002] Cigarette smoke contains harmful substances such as tar, which can be very harmful to the human body if inhaled for a long time. To overcome the harmful substances produced by cigarette combustion, low-harm cigarette alternatives such as e-cigarettes with e-liquids and heat-not-burn e-cigarettes have emerged.

[0003] Among them, traditional heat-not-burn e-cigarettes heat cigarettes and other materials to generate aerosols with higher temperatures. The high-temperature aerosols are directly discharged into the atmosphere from the mouthpiece, which not only wastes heat but also easily burns the mouth, resulting in a poor user experience. Summary of the Invention

[0004] Based on this, it is necessary to provide an atomizing device and an aerosol generating device to address the above problems.

[0005] An atomizing device, comprising:

[0006] a housing, wherein an atomization channel for transmitting the first type of aerosol is provided in the housing;

[0007] An atomizing assembly is provided with an air inlet, an atomizing chamber and an air outlet which are connected in sequence, the air inlet is connected to the atomizing channel, and the atomizing assembly is used to conduct the atomizing medium into the atomizing chamber so that the atomizing medium absorbs the heat emitted by the first type of aerosol and generates a second type of aerosol.

[0008] In the above-mentioned atomizing device, the atomizing chamber is connected to the atomizing channel through the air inlet, and the first type of aerosol in the atomizing channel can flow directly into the atomizing chamber, and its heat can be absorbed by the atomizing medium in the atomizing chamber, so that the atomizing medium evaporates or atomizes to generate the second type of aerosol. Such a setting includes at least the following beneficial effects: first, the atomizing chamber has a heat dissipation effect on the first type of aerosol flowing through it, that is, a temperature reduction treatment; second, the heat emitted by the first type of aerosol can be absorbed by the atomizing medium, avoiding the heat from directly diffusing to the outside of the shell and causing the surface temperature of the shell to be too high, scalding the user and affecting the user experience; third, the second type of aerosol generated after the atomizing medium in the atomizing chamber absorbs the heat is directly mixed with the first type of aerosol, and the aerosol preparation efficiency is high and the mixing is uniform, which is conducive to improving the consistency of the overall concentration of the mixed aerosol, thereby ensuring the stability of the user's inhalation taste.

[0009] In one embodiment, the atomization assembly includes a storage bin for storing the atomizing medium and an atomization pipe connected to the storage bin. The atomization pipe is provided with the air inlet, the atomization chamber, and the air outlet connected in sequence. The atomization pipe is used to conduct the atomizing medium from the storage bin to the atomization chamber. The storage bin can replenish the atomizing medium into the atomization pipe in a timely manner.

[0010] In one embodiment, a partition structure is provided in the atomizing tube, and the partition structure divides at least part of the cavity section of the atomizing cavity into a plurality of mutually independent atomizing sub-cavities. It is understandable that, when the cross-sectional area remains unchanged, the partition structure divides the atomizing cavity into a plurality of independent atomizing sub-cavities, and the total inner wall area of the plurality of atomizing sub-cavities is greater than the inner wall area of a total atomizing cavity, that is, the contact area with the first type aerosol flowing therethrough is increased, which is conducive to the atomizing medium absorbing heat faster and volatilizing or atomizing, while better improving the cooling effect of the atomizing cavity on the first type aerosol flowing therethrough.

[0011] In one embodiment, the atomizing chamber includes a first cavity section and a second cavity section that are interconnected, the second cavity section is located on the side of the atomizing tube close to the atomizing channel and is connected to the atomizing channel through the air inlet, and the partition structure is provided in the second cavity section and divides the second cavity section into a plurality of independent atomizing sub-cavities. For example, when the first type of aerosol with a higher temperature flowing through the atomizing channel flows from the atomizing channel into the plurality of atomizing sub-cavities that first flow into the second cavity section, the atomizing medium in the plurality of independent atomizing sub-cavities is atomized to form the second type of aerosol and mixed with the first type of aerosol to form a plurality of mixed aerosols. The plurality of atomizing sub-cavities are all connected to the first cavity section, and the plurality of mixed aerosols then flow into the first cavity section and are mixed again in the first cavity section to ensure that the aerosols are evenly mixed, which is conducive to further improving the consistency of the overall concentration of the mixed aerosol, thereby better ensuring the stability of the user's inhalation taste.

[0012] In one embodiment, the cross-sectional area of at least a portion of the atomizing sub-chamber shrinks from the air inlet to the air outlet.

[0013] In one embodiment, the cross-sectional area of the atomizing sub-chamber on the side closest to the air inlet is larger than the cross-sectional area of the atomizing sub-chamber on the side closest to the first cavity section. It is understood that within the atomizing sub-chamber, where the cross-sectional area is smaller, the gas flow rate is higher, and the evaporation rate of the atomizing medium is faster, that is, the efficiency of generating the second type of aerosol is also correspondingly improved. At the same time, the aerosols in multiple atomizing sub-chambers have the fastest velocity at the point with the smallest cross-sectional area and converge in the first cavity section, which helps to improve the mixing effect of the aerosols.

[0014] In one embodiment, the partition structure and the atomization tube are integrally formed.

[0015] In one embodiment, the material storage bin is annular and is sleeved on the outer circumference of the atomizing tube. The inner circumference of the material storage bin is provided with a conveying channel connected to the atomizing tube. The material storage bin conducts the atomizing medium through the atomizing tube to the atomizing chamber through the conveying channel.

[0016] In one embodiment, the plurality of delivery channels are provided, and the plurality of delivery channels are spaced apart along the circumference of the atomizing tube. This structural arrangement ensures that the atomizing medium supplied by the storage bin to the atomizing tube is supplied in an even manner, and that the atomizing medium content is evenly distributed throughout the atomizing tube. It is understood that even in the extreme case of partial blockage of a delivery channel, the atomizing medium can still be transported from the remaining delivery channels to the atomizing chamber of the atomizing tube, thereby ensuring the normal generation of the second type of aerosol.

[0017] In one embodiment, the atomization assembly further includes a bracket connected to the shell, the storage bin is disposed in the bracket, and one end of the atomization tube provided with the air inlet is passed through the bracket and communicated with the atomization channel.

[0018] In one embodiment, the bracket includes a cup body and a central tube inserted into the cup body along the axial direction of the cup body, the storage bin is embedded between the inner wall of the cup body and the wall of the central tube, the atomizing tube is sleeved in the central tube, and the delivery channel passes through the wall of the central tube and is connected to the atomizing tube. When the first type of aerosol flows through the atomizing chamber of the atomizing tube, part of the heat of the inner wall of the atomizing chamber can be transferred through the central tube to the atomizing medium in the storage bin, thereby preheating the atomizing medium to a certain extent. For example, when the atomizing medium is tobacco oil, preheating the atomizing medium can reduce the viscosity of the tobacco oil, improve its fluidity, better ensure the supply of atomizing medium in the atomizing chamber, and ensure the atomization effect.

[0019] In one embodiment, the bracket further includes a sealing tube. The sealing tube and the central tube are sequentially sleeved on the outer circumference of the atomizing tube from the inside outward in the radial direction of the atomizing tube, and the delivery channel is radially penetrated through the central tube and the sealing tube. The sealing tube is provided between the atomizing tube and the central tube to prevent leakage of the atomized medium through the gap.

[0020] In one embodiment, the outer circumference of the sealing tube is formed with ribs, which abut the inner circumference of the center tube via the ribs to secure the sealing tube to the center tube. The provision of the ribs not only further enhances the tightness of the contact between the sealing tube and the inner circumference of the center tube, thereby better preventing leakage of the atomized medium, but also increases the friction between the sealing tube and the center tube, preventing misalignment between the sealing tube and the center tube, such as axial misalignment that could lead to blockage of the delivery channel. This improves the stability of the connection between the two and ensures the normal supply of the atomized medium.

[0021] In one embodiment, an oil absorbing member is sleeved on a side of the sealing tube away from the atomizing channel.

[0022] In one embodiment, the oil absorbing member is embedded between the inner circumference of the central tube and the outer circumference of the sealing tube. This arrangement can improve the reliability of the oil absorbing member and further prevent the atomized medium from leaking between the sealing tube and the central tube.

[0023] In one embodiment, a limiting groove is provided at one end of the inner wall of the sealing tube, and one end of the atomizing tube is at least partially inserted into the limiting groove to be fixed to the sealing tube, and the groove wall of the limiting groove is used to limit the movement of the atomizing tube in the axial direction of the sealing tube.

[0024] In one embodiment, the bracket further includes an end cover, which is arranged on an end of the cup body away from the atomization channel. The end cover is provided with a suction nozzle, which is connected to the air outlet.

[0025] In one embodiment, the bracket further includes a sealing cover disposed in the cup body, the sealing cover is sleeved on the outer circumference of the central tube, and is disposed on a side of the storage bin close to the end cover.

[0026] In one embodiment, the bracket encloses to form the storage bin.

[0027] In one embodiment, the atomization tube is a porous tubular structure.

[0028] In one embodiment, the atomizing device further includes a heating assembly disposed within the housing, the heating assembly enclosing the atomizing channel and configured to heat an aerosol-generating substrate within the atomizing channel. The heating assembly can heat the aerosol-generating substrate within the atomizing channel, thereby generating a first type aerosol at a higher temperature.

[0029] The present application also provides an aerosol generating device, which includes a power supply device and the atomization device described in any one of the above embodiments, and the power supply device is electrically connected to the atomization device.

[0030] The above-mentioned aerosol generating device, the atomizing chamber of its atomizing device is connected to the atomizing channel through the air inlet, and the first type of aerosol in the atomizing channel can directly flow into the atomizing chamber, and its heat can be absorbed by the atomizing medium in the atomizing chamber, so that the atomizing medium evaporates to generate the second type of aerosol. Such a setting includes at least the following beneficial effects: first, the atomizing chamber has a heat dissipation effect on the first type of aerosol flowing through it, that is, a temperature reduction treatment; second, the heat emitted by the first type of aerosol can be absorbed by the atomizing medium, avoiding the heat from directly diffusing to the outside of the shell and causing the surface temperature of the shell to be too high, scalding the user and affecting the user experience; third, the second type of aerosol generated after the atomizing medium in the atomizing chamber absorbs the heat is directly mixed with the first type of aerosol, the aerosol preparation efficiency is high and the mixing is uniform, which is conducive to improving the consistency of the overall concentration of the mixed aerosol, thereby ensuring the stability of the user's inhalation taste.

[0040] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The present application provides an aerosol generating device 10, which includes an atomizing device 11 and a power supply device 12. The atomizing device 11 includes a shell 100, an atomizing assembly 200 and a heating assembly 110. The heating assembly 110 is arranged in the shell 100 and encloses an atomizing channel 111. One end of the atomizing channel 111 is exposed to the shell 100 to form a feed port 112. The feed port 112 can be used to add an aerosol generating matrix 20. The power supply device 12 is detachably connected to one end of the atomizing device 11 near the feed port 112, and the power supply device 12 can be used to provide electrical energy to the atomizing device 11. The heating assembly 110 can heat the aerosol generating matrix 20 in the atomizing channel 111, thereby generating a first type of aerosol with a higher temperature. Among them, the aerosol generating matrix 20 can refer to a material that can provide volatile components by heating. For example, the aerosol generating matrix 20 can refer to any material containing tobacco. More specifically, the aerosol-generating substrate 20 may be one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes.

[0042] like Figure 3 and Figure 4As shown, the atomizing assembly 200 is provided with an air inlet 211, an atomizing chamber 212, and an air outlet 213 that are connected in sequence. The air inlet 211 is connected to the atomizing channel 111. The atomizing assembly 200 is used to conduct the atomizing medium into the atomizing chamber 212 so that the atomizing medium generates a second type of aerosol under the heating of the first type of aerosol, that is, the atomizing medium absorbs the heat emitted by the first type of aerosol to generate the second type of aerosol. The atomizing chamber 212 is connected to the atomizing channel 111 via the air inlet 211, and the first type of aerosol in the atomizing channel 111 can flow directly into the atomizing chamber 212. For example, when the first type of aerosol with a higher temperature in the atomizing channel 111 flows into the atomizing chamber 212, its heat can be absorbed by the atomizing medium in the atomizing chamber 212, causing the atomizing medium to volatilize or atomize to generate the second type of aerosol. Such a setting includes at least the following beneficial effects: first, the atomizing chamber 212 has a heat dissipation effect on the first type of aerosol with a higher temperature flowing through it, that is, a cooling treatment; second, the heat emitted by the first type of aerosol can be absorbed by the atomizing medium, thereby preventing the heat from directly diffusing to the outside of the shell 100 and causing the surface temperature of the shell 100 to be too high, scalding the user and affecting the user experience; third, the second type of aerosol generated by the atomizing medium in the atomizing chamber 212 after absorbing the heat is directly mixed with the first type of aerosol, and the aerosol preparation efficiency is high and the mixing is uniform, which is conducive to improving the consistency of the overall concentration of the mixed aerosol, thereby ensuring the stability of the user's inhalation taste.

[0043] Specifically, if Figure 3 、 Figure 4 and Figure 6 As shown, in some embodiments, the atomizing assembly 200 includes a storage bin 220 for storing atomizing medium and an atomizing tube 210 connected to the storage bin 220. The atomizing tube 210 is provided with an air inlet 211, an atomizing chamber 212 and an air outlet 213 that are connected in sequence. The atomizing tube 210 is used to conduct the atomizing medium from the storage bin 220 to the atomizing chamber 212. The storage bin 220 can replenish the atomizing medium into the atomizing tube 210 in a timely manner. Among them, the atomizing tube 210 can be a porous structure, such as ceramic or glass, and is roughly tubular. The porous structure can be considered to be made of a microporous material with a certain porosity. In each embodiment, the porous structure can also be referred to as a hollow porous body, which presents a "porous" form at the microscopic level so as to transport the atomizing medium inside the atomizing tube 210. Due to the characteristics of the porous structure, the atomizing medium is transported to the inner wall of the atomizing chamber 212 by gravity and capillary action, so that the atomizing medium can generate the second type of aerosol under the heating of the first type of aerosol flowing through it.

[0044] More specifically, if Figure 4 、 Figure 5 and Figure 6As shown, in some embodiments, a partition structure 214 is provided in the atomizing tube 210, and the partition structure 214 divides at least part of the cavity section of the atomizing chamber 212 into a plurality of mutually independent atomizing sub-cavities 215. It can be understood that, when the cross-sectional area remains unchanged, the partition structure 214 divides the atomizing chamber 212 into a plurality of independent atomizing sub-cavities 215, and the total inner wall area of the plurality of atomizing sub-cavities 215 is greater than the inner wall area of the total atomizing chamber 212, that is, the contact area with the first type of aerosol flowing therethrough is increased, which is conducive to the atomizing medium absorbing heat faster and volatilizing or atomizing, while better improving the cooling effect of the atomizing chamber 212 on the first type of aerosol flowing therethrough. Among them, "plurality" can be considered as "at least two". In one embodiment, the cross-sectional areas of the plurality of independent atomizing sub-cavities 215 can be equal; in another embodiment, the cross-sectional areas of the plurality of independent atomizing sub-cavities 215 can also be unequal.

[0045] For more details, please refer to Figure 4 and Figure 6 In some embodiments, the atomizing chamber 212 includes a first cavity section H1 and a second cavity section H2 that are interconnected. The second cavity section H2 is located on a side of the atomizing tube 210 close to the atomizing channel 111 and is connected to the atomizing channel 111 through the air inlet 211. The partition structure 214 is provided in the second cavity section H2 and divides the second cavity section H2 into a plurality of independent atomizing sub-cavities 215. For example, when the first type aerosol with a higher temperature in the atomizing channel 111 flows from the atomizing channel 111 into the plurality of atomizing sub-cavities 215 that first flow into the second cavity section H2, the atomizing media in the plurality of independent atomizing sub-cavities 215 are uniformly atomized to form the second type aerosol, which is then mixed with the first type aerosol to form a plurality of mixed aerosols. The multiple atomizing sub-cavities 215 are all connected to the first cavity section H1. The multiple mixed aerosols then flow into the first cavity section H1 and are mixed again in the first cavity section H1, ensuring that the aerosols are mixed evenly, which is conducive to further improving the consistency of the overall concentration of the mixed aerosol, thereby better ensuring the stability of the user's inhalation taste.

[0046] Please continue reading Figure 4 and Figure 6 In some embodiments, the cross-sectional area of at least a portion of the atomizing sub-chamber 215 shrinks from the air inlet 211 to the air outlet 213. Figure 3 and Figure 4In the illustrated embodiment, the cross-sectional area of the atomizing sub-chamber 215 near the air inlet 211 is larger than the cross-sectional area of the atomizing sub-chamber 215 near the first cavity segment H1. It is understood that within the atomizing sub-chamber 215, where the cross-sectional area is smaller, the gas flow rate is higher, the evaporation rate of the atomizing medium is faster, and the efficiency of aerosol generation is correspondingly improved. At the same time, the aerosols within the multiple atomizing sub-chambers 215 have the fastest velocity at the point with the smallest cross-sectional area and converge in the first cavity segment H1, which helps to improve the mixing effect of the aerosols.

[0047] It should be noted that, in some embodiments, the partition structure 214 is integrally formed with the atomizing tube 210, that is, the partition structure 214 can be considered as a partially extended structure of the atomizing tube 210 protruding from the inner wall of the atomizing chamber 212, and can be in the shape of a plate, a sheet, etc. The specific structure of the partition structure 214 is not limited here, and it is only necessary that the partition structure 214 can separate the atomizing chamber 212 into multiple independent atomizing sub-chambers 215. In other embodiments, the partition structure 214 can also be an independent structural component, that is, the partition structure 214 can be set in the atomizing chamber 212 of the atomizing tube 210 by ultrasonic welding, bonding, clamping, etc.

[0048] Please refer to Figure 3 and Figure 4 In some embodiments, the storage bin 220 is annular and is sleeved on the outer circumference of the atomizing tube 210. The inner circumference of the storage bin 220 is provided with a delivery channel 221 connected to the atomizing tube 210. The storage bin 220 transmits the atomized medium through the atomizing tube 210 to the atomizing chamber 212 through the delivery channel 221. For example, Figure 4 and Figure 5 As shown, in some embodiments, a plurality of delivery channels 221 are provided, and the plurality of delivery channels 221 are spaced apart along the circumference of the atomizing tube 210. Such a structural arrangement ensures that the storage bin 220 supplies the atomizing medium to the atomizing tube 210 and that the atomizing medium content at various locations in the atomizing tube 210 is balanced. It is understandable that, even in the extreme case of partial blockage of a delivery channel 221, the atomizing medium can still be transferred from the remaining delivery channels 221 to the atomizing chamber 212 of the atomizing tube 210, thereby ensuring the normal generation of the second type of aerosol.

[0049] Please refer to Figure 3 and Figure 4In some embodiments, the atomizer assembly 200 further includes a bracket 230 connected to the housing 100. The material storage bin 220 is disposed within the bracket 230. One end of the atomizer tube 210 passes through the bracket 230 and communicates with the atomization channel 111. In one embodiment, the material storage bin 220 can be considered an independent structural component. In another embodiment, the material storage bin 220 can also be considered to be formed by the structure of the bracket 230, and the delivery channel 221 is opened in the bracket 230.

[0050] Specifically, if Figure 4 and Figure 5 As shown, in some embodiments, the bracket 230 includes a cup body 231 and a central tube 232 inserted into the cup body 231 along the axial direction of the cup body 231. The storage bin 220 is embedded between the inner wall of the cup body 231 and the tube wall of the central tube 232, the atomizing tube 210 is sleeved in the central tube 232, and the delivery channel 221 is passed through the tube wall of the central tube 232 and communicates with the atomizing tube 210. Among them, the central tube 232 can be a metal tube such as a steel pipe, which has better thermal conductivity. In one embodiment, the storage bin 220 can also be considered to be formed by the inner wall of the cup body 231 and the outer tube wall of the central tube 232. When the first type of aerosol flows through the atomizing chamber 212 of the atomizing tube 210, part of the heat of the inner wall of the atomizing chamber 212 can be transferred to the atomizing medium in the storage bin 220 through the central tube 232, thereby preheating the atomizing medium to a certain extent. For example, when the atomizing medium is e-liquid, preheating the atomizing medium can reduce the viscosity of the e-liquid, improve its fluidity, better ensure the supply of atomizing medium in the atomizing chamber 212, and ensure the atomization effect.

[0051] More specifically, if Figure 4 and Figure 5 As shown, in some embodiments, the bracket 230 further includes a sealing tube 233, and the sealing tube 233 and the center tube 232 are sequentially sleeved on the outer circumference of the atomizing tube 210 from the inside to the outside along the radial direction of the atomizing tube 210, and the delivery channel 221 is provided in the center tube 232 and the sealing tube 233 along the radial direction of the atomizing tube 210. It can be considered that the delivery channel 221 simultaneously penetrates the circumference of the center tube 232 and the sealing tube 233, and it can be considered that the delivery channel 221 is formed by two mutually communicating through holes opened on the circumference of the center tube 232 and the sealing tube 233. The sealing tube 233 is provided between the atomizing tube 210 and the center tube 232 to prevent the atomized medium from leaking from the gap.

[0052] More specifically, if Figure 4 and Figure 5As shown, in some embodiments, a rib 2331 is formed on the outer circumference of the sealing tube 233. The sealing tube 233 abuts the inner circumference of the center tube 232 via the rib 2331 to secure the sealing tube 233 to the center tube 232. The provision of the rib 2331 can, on the one hand, further enhance the tightness of the contact between the sealing tube 233 and the inner circumference of the center tube 232, thereby better preventing leakage of the atomized medium. On the other hand, it can enhance the friction between the sealing tube 233 and the center tube 232, thereby preventing misalignment between the sealing tube 233 and the center tube 232, such as axial misalignment that could cause blockage of the delivery channel 221. This can both enhance the stability of the connection between the two and ensure the normal supply of the atomized medium.

[0053] More specifically, if Figure 4 and Figure 5 As shown, in some embodiments, the sealing tube 233 is provided with an oil absorbing member 234 on one side away from the atomizing channel 111. The oil absorbing member 234 may be made of non-woven cotton or the like. Figure 4 In the illustrated embodiment, oil absorbing member 234 is embedded between the inner circumference of central tube 232 and the outer circumference of sealing tube 233. This arrangement not only improves the reliability of oil absorbing member 234 but also further prevents leakage of atomized medium between sealing tube 233 and central tube 232.

[0054] More specifically, if Figure 4 and Figure 5 As shown, in some embodiments, a limiting groove 2332 is provided at one end of the inner wall of the sealing tube 233, and one end of the atomizing tube 210 is at least partially inserted into the limiting groove 2332 to be fixed to the sealing tube 233, and the groove wall 2333 of the limiting groove 2332 is used to limit the axial movement of the atomizing tube 210 in the sealing tube 233.

[0055] More specifically, if Figure 4 and Figure 5 As shown, in some embodiments, the bracket 230 further includes a sealing cover 235 disposed in the cup body 231 , the sealing cover 235 is sleeved on the outer circumference of the central tube 232 , and is covered on one side of the storage bin 220 close to the end cover 236 .

[0056] More specifically, if Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, the bracket 230 further includes an end cap 236, which is disposed on an end of the cup body 231 away from the atomization channel 111 and is engaged with the cup body 231 at its periphery. The end cap 236 is provided with a suction nozzle 120, which is in communication with the air outlet 213.

[0057] Furthermore, in some embodiments, the heating assembly 110 may also refer to an atomizer core for heating e-liquid. It is understood that the aerosol formed by the heating assembly 110 heating the e-liquid may also be considered a high-temperature first-class aerosol. In other words, the aerosol generating device 10 may also refer to other types of e-cigarettes besides heat-not-burn e-cigarettes, such as e-cigarettes that use e-liquid.
