[0026] Please refer to Figure 1-5 The present application provides an aerosol generating device, which includes a heating element 10 and a base assembly. The heating element 10 has a heating chamber 11 inside, and the heating chamber 11 is used to accommodate an aerosol generating substrate 40. The aerosol generating substrate 40 may specifically include a plant grass leaf substrate, such as a tobacco substrate. The aerosol generating substrate 40 may also include a protective cover, which may wrap the plant grass leaf substrate, for example, the plant grass leaf substrate may be wrapped inside an aluminum foil or paper for use. Figure 1 and Figure 2 The aerosol generating device may not include the aerosol generating substrate 40, and the aerosol generating substrate 40 is only used as a consumable material, such as Figure 3 and Figure 4 The aerosol generating device may also include an aerosol generating substrate 40, depending on the circumstances.
[0027] like Figure 1 and Figure 2 As shown, the heating element 10 may specifically include a substrate 12 and a heating portion 13. The substrate 12 is enclosed to form a tubular structure, and the interior of the tubular structure has a heating cavity 11. The heating portion 13 is arranged on the side surface of the tubular structure, for example, it can be arranged on the outer side or the inner side of the tubular structure to heat the interior of the heating cavity 11 in the circumferential direction, so that the aerosol generating matrix 40 generates aerosol. The heating portion 13 may be in the form of a heating film, a heating wire, a heating net, a heating sheet, etc., and the present application does not limit the structural form of the heating portion 13.
[0028] Generally, the aerosol generating device comprises a housing (not shown), the housing is provided with an opening, the opening is arranged opposite to the heating chamber 11, and the aerosol generating substrate 40 can be inserted into or withdrawn from the heating chamber 11 through the opening, so as to facilitate the replacement of the aerosol generating substrate 40. The base assembly is arranged on a side of the heating element 10 away from the opening.
[0029] Specifically, Figure 1-5 As shown, the base assembly includes an air inlet portion 21, a liquid storage portion 22 and an airway portion 23. The air inlet portion 21 has an air inlet channel 211 inside, the liquid storage portion 22 has a liquid storage cavity 221 inside, and the airway portion 23 has an air guide channel 231 inside. The airway portion 23 has a first end and a second end opposite to each other along the extension direction of the air guide channel 231, and the air guide channel 231 has a first end and a second end opposite to each other along the extension direction of the air guide channel 231; the heating element 10 is arranged at the first end of the airway portion 23, and in one embodiment, a step 232 is provided at one end of the airway portion 23 close to the heating element 10, and the step 232 is used to install the heating element 10 and the components inside the heating element 10. The heating chamber 11 is connected to the first end of the air guiding channel 231 so that the gas in the air guiding channel 231 can enter the interior of the aerosol generating substrate 40 in the heating chamber 11, thereby carrying the aerosol generated by the aerosol generating substrate 40, and finally overflowing from the end of the aerosol generating substrate 40 away from the air guiding channel 231 for use by the user.
[0030] The liquid storage portion 22 is disposed at the second end of the airway portion 23, and the liquid storage cavity 221 is connected to the second end of the air guide channel 231, so that the liquid storage cavity 221 can collect the condensed liquid in the air guide channel 231, that is, the condensed liquid can flow to the liquid storage cavity 221 along the inner wall of the air guide channel 231. The air inlet portion 21 has a first end and a second end along the extension direction of the air inlet channel 211. The first end of the air inlet portion 21 is disposed inside the air guide channel 231 and outside the liquid storage cavity 221. Specifically, the first end of the air inlet portion 21 can be disposed at an end of the air guide channel 231 away from the heating element 10; the first end of the air inlet portion 21 can also be disposed at an end of the air guide channel 231 close to the heating element 10, so that the downward flow path of the liquid and the upward flow path of the gas are as independent as possible.
[0031] One end of the air inlet channel 211 is connected to the air guide channel 231, and the other end of the air inlet channel 211 is connected to the external atmosphere. Generally, an air inlet hole is provided on the housing, and the air inlet channel 211 can be connected to the air inlet hole, so that the air inlet channel 211 is connected to the external atmosphere.
[0032] The aerosol generating device provided in the present application is provided with an air inlet portion 21, a liquid storage portion 22 and an airway portion 23. The liquid storage portion 22 has a liquid storage chamber 221 capable of collecting condensed liquid. The liquid storage chamber 221 is connected to the heating chamber 11 through an air guide channel 231. Therefore, the condensed liquid generated by the heating chamber 11 and / or the air guide channel 231 can flow along the air guide channel 231 to the liquid storage chamber 221 for collection, thereby preventing the condensed liquid from flowing around and affecting the use of other components, and also preventing the condensed liquid from flowing out of the aerosol generating device and causing dirt.
[0033] In addition, the present application arranges the first end of the air inlet portion 21 inside the air guide channel 231 and outside the liquid storage chamber 221, so that the airflow entering the air inlet channel 211 from the air inlet hole may not flow through the liquid storage chamber 221, that is, the air inlet channel 211 and the liquid storage chamber 221 are two relatively independent spaces. Since a large amount of condensate is collected in the liquid storage chamber 221, the condensate has a strong taste. If the airflow entering the air inlet channel 211 from the air inlet hole flows through the liquid storage chamber 221, it may cause the suction taste to be not pure enough. The present application arranges the air inlet channel 211 and the liquid storage chamber 221 as two relatively independent spaces, which can ensure that the gas does not contact the gas in the liquid storage chamber 221 as much as possible during air intake, thereby ensuring the purity of the suction taste.
[0034] In one embodiment, if Figure 2 and Figure 6 As shown, there is a gap 24 between the outer side surface of the first end of the air inlet 21 and the inner side surface of the air guide channel 231, wherein the "outside" and "inside" of the air inlet 21 are defined relative to the air inlet channel 211, the inner wall of the air inlet channel 211 is the inner side surface of the air inlet 21, and the inner side surface of the air inlet 21 is arranged opposite to the outer side surface. One end of the gap 24 is connected to the air guide channel 231, and the other end of the gap 24 is connected to the liquid storage chamber 221, so that the condensate on the inner side surface of the air guide channel 231 can be guided into the liquid storage chamber 221 through the gap 24. Since some condensate will flow along the inner side surface of the air guide channel 231 toward the liquid storage chamber 221, the condensate will flow into the gap 24 and be guided into the liquid storage chamber 221 along the gap 24. Since the gap 24 is located on the outside of the air inlet portion 21 and the air inlet channel 211 is located on the inside of the air inlet portion 21, the liquid channel and the gas channel are separated into two relatively independent spaces by the air inlet portion 21 to ensure the purity of the smoking taste.
[0035] In one embodiment, if Figure 2As shown, the first end of the air inlet 21 is provided with a guide portion 25, and the guide portion 25 has a through hole 251 inside. One end of the through hole 251 is connected to the air inlet channel 211, and the other end of the through hole 251 is connected to the air guide channel 231. The guide portion 25 has a first end close to the heating chamber 11 and a second end away from the heating chamber 11. The first distance between the outer side surface of the first end of the guide portion 25 and the inner side surface of the air guide channel 231 is greater than the second distance between the outer side surface of the second end of the guide portion 25 and the inner side surface of the air guide channel 231. Among them, the "outside" and "inside" of the guide portion 25 are defined relative to the through hole 251, and the inner wall of the through hole 251 is the inner side surface of the guide portion 25, and the inner side surface and the outer side surface of the guide portion 25 are arranged opposite to each other.
[0036] Specifically, the radial dimension of the guide portion 25 gradually shrinks in the direction approaching the heating element 10 so that the first spacing is greater than the second spacing. For example, when the transverse cross section of the guide portion 25 is circular, the radial dimension of the guide portion 25 is the diameter. When the transverse cross section is a figure of other shapes, the radial dimension of the guide portion 25 is the length of the line connecting the two farthest points in the figure. For example, when the transverse cross section is a rectangle, the radial dimension of the guide portion 25 is the diagonal of the rectangle. The above design of the guide portion 25 can make the guide portion 25 roughly conical. By arranging the guide portion 25 at the first end of the air inlet portion 21, the present application can guide a small amount of condensate attached to the top of the guide portion 25 into the gaps 24 on both sides, thereby further collecting the liquid in the liquid storage chamber 221 and minimizing the condensate at the top of the guide portion 25 from flowing into the through hole 251.
[0037] In one embodiment, if Figure 1 and Figure 2 As shown, the base assembly includes a bracket 26, a first sealing member 27, and a second sealing member 28. The bracket 26 includes an airway portion 23 and an air inlet portion 21. In one embodiment, the bracket 26 also includes a connecting portion 261, and the connecting portion 261 connects the airway portion 23 and the air inlet portion 21. The bracket 26 is integrally formed to reduce the steps of the assembly process. In other embodiments, the airway portion 23 and the air inlet portion 21 can also be two detachable parts of the bracket 26.
[0038] The first sealing member 27 and the second sealing member 28 form a liquid storage portion 22. One end of the first sealing member 27 is connected to one end of the airway portion 23 away from the heating member 10. The first sealing member 27 has a first inner cavity 271 inside, one end of the first inner cavity 271 is connected to the air guide channel 231, and the second sealing member 28 blocks the other end of the first inner cavity 271, so that the inner wall of the first inner cavity 271 and the second sealing member 28 jointly define the liquid storage cavity 221. The second end of the air inlet portion 21 is arranged inside the liquid storage cavity 221, and one end of the second sealing member 28 close to the heating member 10 is connected to the second end of the air inlet portion 21, and the second sealing member 28 has a second inner cavity 281 inside, one end of the second inner cavity 281 is connected to the air inlet channel 211, and the other end of the second inner cavity 281 is connected to the external atmosphere through the air inlet hole of the shell.
[0039] In one embodiment, the central axis of the first inner cavity 271, the central axis of the second inner cavity 281, the central axis of the air intake channel 211 and the central axis of the air guide channel 231 are located on the same straight line so that the air intake route of the airflow is a straight line. In other embodiments, the air intake channel 211 and the second inner cavity 281 can also be set away from the central axis of the first inner cavity 271.
[0040] In one embodiment, the first sealing member 27 is connected to the airway portion 23 by interference fit, the second sealing member 28 is connected to the inner wall of the first inner cavity 271 by interference fit, and the end of the second sealing member 28 close to the heating member 10 is connected to the air inlet portion 21 by interference fit. The interference fit connection of each part can improve the air tightness of the base assembly, ensuring that there will be no air leakage during the suction process, and in addition, it can also ensure that the condensate will not leak from the base assembly during the collection process.
[0041] In one embodiment, in order to ensure the reliability of the interference fit connection, the first seal 27 is configured as a first seal 27 made of silicone, and the second seal 28 is configured as a second seal 28 made of silicone. Figure 1 and Figure 2 In the embodiment, the bracket 26 and the first seal 27 are two detachable parts. In other embodiments, the bracket 26 and the first seal 27 can also be an integrally formed part to reduce the steps of the assembly process, and only the second seal 28 is configured as a silicone second seal 28.
[0042] In one embodiment, the base assembly may further include a heating unit (not shown), which is disposed inside the liquid storage chamber 221 to heat and evaporate the condensed liquid in the liquid storage chamber 221. The provision of the heating unit allows the condensed liquid in the liquid storage chamber 221 to be cleaned out of the liquid storage chamber 221 by heating and evaporation, without the need to disassemble the base assembly for cleaning, thereby greatly simplifying the cleaning steps, reducing the difficulty of cleaning, and improving the cleaning efficiency.
[0043] In one embodiment, if Figure 1 and Figure 2 As shown, the aerosol generating device further comprises a heat exchange member 30, the interior of the heat exchange member 30 is provided with a heat exchange hole 31 penetrating the heat exchange member 30, at least a portion of the heat exchange member 30 is disposed inside the heating chamber 11, one end of the heat exchange hole 31 is communicated with the air guide channel 231, and the other end of the heat exchange hole 31 is communicated with the heating chamber 11, and the heating member 10 is used to heat the gas inside the heat exchange hole 31. By heating the gas inside the heat exchange hole 31 by the heating portion of the heating member 10, the gas entering the aerosol generating substrate 40 can be preheated, that is, the aerosol generating substrate 40 is heated by the hot air flow, and the hot air flow can improve the uniformity of the heating temperature of the aerosol generating substrate 40 in the radial direction, and cooperate with the circumferential heating of the heating portion on the circumferential side of the aerosol generating substrate 40, the heating efficiency of the heating member 10 can be improved.
[0044] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of the present invention.
