Description

Technical Field

[0001] The present application relates to the technical field of aerosol generation, and more specifically, to a heater and an aerosol generation device. Background Art

[0002] An aerosol generation device can heat an aerosol substrate in a non-combustion manner through heating, so that the aerosol substrate is atomized to form an aerosol that can be sucked by a user. Some existing aerosol generation devices have an air inlet channel and a heating channel. The air inlet channel is arranged at the top of the aerosol generation device. During use, part of the generated aerosol flows to the top for the user to use, and part of the aerosol condenses and diffuses in the entire air inlet channel and heating channel of the aerosol generation device, and even leaks to the outside of the aerosol generation device. When the user uses it next time, the condensed aerosol in the air inlet channel and heating channel will produce an odor, affecting the taste during use, and thus affecting the user experience.

[0010] In one embodiment, the axis of the heating channel is a straight line arranged along the length direction; the liquid flow direction of the liquid collection port is parallel to the length direction; the axial direction of the liquid collection channel is perpendicular to the length direction.

[0011] In one embodiment, the liquid collection member further includes a blocking element. The liquid collection channel is provided with a liquid inlet and a liquid outlet oppositely along its axial direction. The liquid inlet is communicated with the liquid collection port, and the blocking element is arranged at the liquid outlet to block or open the liquid outlet.

[0012] In one embodiment, at least a part of the orthographic projection of the second opening along the length direction overlaps with the orthographic projection of the liquid collection port along the length direction.

[0013] In one embodiment, the orthographic projection of the liquid collection port along the length direction completely covers the orthographic projection of the second opening along the length direction.

[0014] In one embodiment, a plurality of the liquid collection ports and a plurality of the liquid collection channels are provided, and at least one of the liquid collection ports corresponds to each of the liquid collection channels.

[0015] In one embodiment, the liquid collection ports and the liquid collection channels are arranged in one-to-one correspondence.

[0016] In one embodiment, the heater further has an air flow channel, and the air flow channel is communicated with the external environment through the first opening; the air flow channel is communicated with the heating channel so that external air sequentially passes through the first opening, the air flow channel and the second opening and enters the heating channel; the liquid collection member is arranged at an interval from the second opening to form a part of the air flow channel between the liquid collection member and the second opening.

[0017] The present application provides an aerosol generating device, which includes a housing, a power supply component and the heater as described above. The power supply component and the heater are arranged in the housing, and the power supply component is electrically connected to the heater to provide the power required for the operation of the heater.

[0018] According to the heater in the above embodiments, it includes a bracket assembly, a heating channel, a heating component, and a liquid collecting component.

For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and general technical knowledge in the art.

[0027] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners, and the operation steps involved in each embodiment can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a certain embodiment, and do not mean to be the necessary composition and / or order.

[0028] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0029] The present application provides an aerosol generating device (hereinafter referred to as the generating device), which can be used to heat the aerosol matrix A to generate an aerosol that can be used.

[0030] It should be noted that the aerosol referred to in the terminology means a dispersion of solid particles or liquid particles in a gas. As used herein, "aerosol" generally refers to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0031] As used herein, the term "aerosol matrix A" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the operating temperature of the system) during use. Suitable aerosol matrices A are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as glycerol mono-, di-, or triacetate; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate.

[0032] The aerosol matrix A may include nicotine. The aerosol matrix A may include water. The aerosol matrix A may include glycerol (also known as glycerin) having a boiling point higher than that of nicotine. The aerosol matrix A may include propylene glycol. The aerosol matrix A may include plant-based materials. The aerosol matrix A may include a homogeneous plant matrix material. The homogeneous plant matrix material may contain volatile compounds. These compounds may be released from the aerosol matrix A upon heating. The aerosol matrix A may be contained in a container to form a columnar structure with a preset length, etc.

[0033] Please refer to Figure 1 , the generating device includes a housing 100, a heater 200, and a power supply component 300. An installation space 110 is provided inside the housing 100. Both the heater 200 and the power supply component 300 are arranged in the installation space 110. The power supply component 300 is electrically connected to the heater 200 to provide the power required for the heater 200 to operate and control its operation. The housing 100 can be understood as a collection of relevant components that constitute the overall outer contour of the generating device. For example, the housing 100 can be assembled by combining one or more components, and corresponding assembly structures are provided inside the housing 100 or on the housing wall to assemble other components of the generating device to the housing 100. For example, the PCB control circuit board (not shown in the figure) and the battery (not shown in the figure) in the power supply component 300 can be assembled inside the housing 100, and the operation buttons in the power supply component 300 can be installed on the housing 100 in a manner that is exposed outside the housing 100. With the help of the housing 100, users can carry, move, operate, and use the generating device.

[0034] It should be noted that the outer casing 100 and the power supply component 300 are technologies disclosed in the prior art and are not the core protected by this application, so they will not be elaborated here. The heater 200 to be protected by this application will be introduced in detail below.

[0035] Please refer to Figures 1 to 6 , the heater 200 includes a bracket assembly 210, a heating channel 220, a heating component 230, and a liquid collecting member 240. The heating channel 220 has a first opening 221 and a second opening 222 oppositely arranged along its length direction. The first opening 221 is used for inserting the aerosol matrix A into the heating channel 220. The heating component 230 is used for heating the aerosol matrix A to generate aerosol. The heating component 230 is arranged inside the bracket assembly 210. At least part of the heating component 230 cooperates with the bracket assembly 210 to define and form the heating channel 220, and the second opening 222 is formed at the heating component 230. After being powered on, the heating component 230 generates heat and can directly or indirectly heat the aerosol matrix A to atomize it into aerosol. The aerosol flows along the direction from the second opening 222 to the first opening 221 for user use; the liquid collecting member 240 is detachably arranged inside the bracket assembly 210. The liquid collecting member 240 includes a liquid collecting port 241 and a liquid collecting channel 242. The liquid collecting port 241 is oppositely arranged to the second opening 222. The liquid collecting port 241 and the liquid collecting channel 242 are communicated so that the residue flows into the liquid collecting channel 242 through the second opening 222 and the liquid collecting port 241 in sequence.

[0036] After the user uses the generating device, the residue will flow in the heating channel 220 of the generating device and will condense after the temperature drops. The condensed residue will flow inside the generating device or flow to its outside. On the one hand, the internal residue will produce an odor when the user uses the generating device again, affecting the user's taste. On the other hand, the residue will corrode the entire generating device and affect its service life.

[0037] Since the aerosol matrix A is disposed within the heating channel 220, the aerosol formed by heating it also flows through the heating channel 220 to the user end, i.e., in the direction close to the first opening 221. The residual aerosol flows in the direction away from the user end (i.e., the direction close to the second opening 222) as a residue. The liquid collection port 241 of the liquid collection member 240 is disposed opposite to the second opening 222, and the residue flowing out from the second opening 222 can be collected by the liquid collection port 241. After the liquid collection port 241 collects the residue, it guides the residue into the liquid collection channel 242 for storage, which can achieve the purpose of collecting the residue, avoid the generation of peculiar smell due to the long stacking time of the residue, improve the user's taste, and also avoid the random flow of the residue, extend the service life of the generating device, and thus improve the user experience. Since the heating component 230 and the support component 210 cooperate to form the heating channel 220, the second opening 222 is formed at the heating component 230, and the second opening 222 is disposed opposite to the liquid collection port 241, so that the flow distance of the residue during collection is short and the temperature does not drop significantly, which facilitates the residue to flow into the liquid collection channel 242 for collection and reduces the possibility of condensation of the residue in the heating channel 220.

[0038] Please refer to Figure 6 , in an embodiment, the liquid collection member 240 further includes a diversion surface 243 disposed between the liquid collection port 241 and the liquid collection channel 242 for guiding the residue to flow from the liquid collection port 241 into the liquid collection channel 242; the diversion surface 243 is inclined towards the liquid collection channel 242 along the liquid flow direction of the liquid collection port 241.

[0039] It should be further noted that the residue mentioned herein is aerosol, which will condense after the temperature drops. Based on the composition characteristics of the aerosol matrix A, the residue has poor fluidity and strong viscosity after condensation. When the generating device is in use, the first opening 221 and the second opening 222 are generally arranged along the vertical direction. Under the action of gravity, the residue is facilitated to flow out from the second opening 222 and flow into the liquid collection port 241, which can reduce the possibility of accumulation residue in the heating channel 220. The diversion surface 243 is inclined towards the liquid collection channel 242 along the liquid flow direction of the liquid collection port 241, so that the residue can flow into the liquid collection channel 242 along the diversion surface 243 under the action of gravity during use for storage, which can reduce the residue retention at the liquid collection port 241 and avoid the residue flowing back from the liquid collection port 241 to the second opening 222 or other components of the generating device (such as the support component 210 or the heating component 230) when moving, using or placing the generating device, thus avoiding the pollution caused by the residue backflow.

[0040] Furthermore, in order to better store the residue, a storage component, such as storage cotton, is provided in the liquid collection channel 242, which can further prevent the residue from flowing back. At the same time, after a certain amount of residue is collected, the purpose of cleaning the liquid collection component 240 can be achieved by discarding and replacing the storage component, thereby reducing material consumption.

[0041] In one embodiment, the axis of the heating channel 220 is a straight line arranged along the length direction, that is, the heating channel 220 is a straight channel, which shortens the flow distance of the aerosol, so that the aerosol can be discharged from the heating channel 220, and the residue can flow into the liquid collecting part 240 under the action of gravity to prevent it from flowing to other parts (such as the bracket assembly 210). The liquid flow direction of the liquid collecting port 241 is parallel to the length direction, that is, the liquid flow direction in the liquid collecting port 241 is still along the vertical direction, so that the residue can flow under the action of gravity. The liquid collecting channel 242 extends from the output end of the guide surface 243 to the edge of the liquid collecting part 240, which can effectively utilize the overall space of the liquid collecting part 240.

[0042] In one embodiment, the axial direction of the liquid collecting channel 242 is perpendicular to the length direction, that is, the liquid collecting channel 242 is arranged horizontally and extends radially along the liquid collecting part 240. The residue is stored in the liquid collecting channel 242, which can avoid the possibility of it flowing back to the liquid collecting port 241 or even flowing back to the heating channel 220.

[0043] See also Figure 6 In one embodiment, the liquid collecting part 240 also includes a blocking element 244. The liquid collecting channel 242 is provided with a liquid inlet 2421 and a liquid outlet 2422 along its axial direction. The liquid inlet 2421 is connected to the liquid collecting port 241. The blocking element 244 is arranged at the liquid outlet 2422 to block or open the liquid outlet 2422. The setting of the blocking element 244 facilitates the cleaning of the residue stored in the liquid collecting channel 242.

[0044] When in use, the liquid collecting piece 240 is a consumable material, and it is detachably arranged with the support assembly 210, so that it is convenient to remove it from the support assembly 210. When there are a lot of residues stored in the liquid collecting piece 240, the liquid collecting piece 240 can be directly removed and discarded. After the blocking element 244 is set, it is convenient to open the liquid outlet 2422, so as to facilitate cleaning of the residues stored in the liquid collecting channel 242, which can reduce the loss of the liquid collecting piece 240 and reduce the cost.

[0045] The liquid collecting parts 240 are all made of silicone material, which is easy to obtain, convenient to process, and low in cost. When used as consumables, the cost can be effectively controlled. The diameter of the liquid collecting channel 242 is 1.0mm-1.6mm, which can effectively ensure the collection effect of the residue.

[0046] In one embodiment, the second opening 222 at least partially overlaps with the orthographic projection of the liquid collecting port 241 along the length direction.

[0047] In one embodiment, the positive projection of the liquid collection port 241 along the length direction of the heating channel 220 completely covers the positive projection of the second opening 222 along the length direction of the heating channel 220, so that the residues flowing out from the second opening 222 can be completely collected by the liquid collection port 241.

[0048] In one embodiment, there are multiple liquid collection ports 241 and multiple liquid collection channels 242, and at least one liquid collection port 241 is correspondingly provided for each liquid collection channel 242. Specifically, the liquid collection member 240 is generally cylindrical, and the multiple liquid collection ports 241 are uniformly arranged along the cross-section of the cylinder. The liquid collection channels 242 extend along the radial direction of the cylinder, and at least one liquid collection port 241 is correspondingly connected to each liquid collection channel 242, which can prevent residues from accumulating at the liquid collection ports 241.

[0049] Please refer to Figure 5 and Figure 6 , in one embodiment, the liquid collection ports 241 and the liquid collection channels 242 are provided in a one-to-one correspondence. For example, there are 4 liquid collection ports 241 and 4 liquid collection channels 242, and the 4 liquid collection ports 241 are uniformly arranged along the cross-section of the cylinder to form a circle, which can collect residues in all directions. Of course, in other embodiments, the number of the liquid collection ports 241 and the liquid collection channels 242 can also be set to 2, 3, 6, or 8.

[0050] In one embodiment, the heater 200 further has an air flow channel 250. The air flow channel 250 is communicated with the external environment through the first opening 221, and the air flow channel 250 is communicated with both the first opening 221 and the second opening 222. External air enters the heating channel 220 in sequence through the first opening 221, the air flow channel 250, and the second opening 222; the liquid collection member 240 is spaced from the second opening 222 to form a part of the air flow channel 250 between the liquid collection member 240 and the second opening 222.

[0051] According to the usage habit, the first opening 221 is arranged at the top, and the liquid collection member 240 is arranged below the second opening 222. External air enters from the top of the generating device and enters the heating channel 220 from the second opening 222 under the suction action, and then flows upward along the heating channel 220. The residues flow downward from the second opening 222 into the liquid collection port 241 under the action of gravity, and the residues will not flow into the air flow channel 250, which can prevent the residues from polluting the air flow channel 250 and blocking the air flow channel 250.

[0052] Please refer to Figure 3, the bracket assembly 210 includes a first tube body 211, a second tube body 212, and a base 213. A first opening 221 is formed on the first tube body 211. At least part of the structure of the first tube body 211 is inserted into the second tube body 212. The heating assembly 230 is disposed in the second tube body 212 and is connected (or abutted) to the first tube body 211 to form a heating channel 220. The first tube body 211, the second tube body 212, and the heating assembly 230 cooperate to form an air flow channel 250. The base 213 is disposed in the second tube body 212 and is arranged away from the first tube body 211 to seal one end of the second tube body 212. The liquid collecting member 240 is disposed at one end of the base 213 close to the first tube body 211. The liquid collecting member 240 can be fixed by the arrangement of the base 213. The base 213 is detachably connected to the second tube body 212, facilitating the removal of the liquid collecting member 240.

[0053] Please refer to Figure 3 , the heating assembly 230 includes a heating tube 231 and a heat exchange core 232. The heating tube 231 and the first tube body 211 cooperate to form a heating channel 220. The heat exchange core 232 is disposed in the heating tube 231 and is arranged close to the second opening 222. After the heating tube 231 is powered on and generates heat, it can heat the air entering the heat exchange core 232 to form a hot air flow. The hot air flow flows into the aerosol matrix A along the heating channel 220, and the aerosol matrix A is heated by the hot air flow. Since the heating tube 231 and the first tube body 211 cooperate to form the heating channel 220, the heating tube 231 can also directly heat the aerosol matrix A.

[0054] In one embodiment, the heating tube 231 is made of a conductive material and can be directly powered on to generate heat, or the heating tube 231 includes a tube body with heat conduction performance and a heating wire (resistance wire) disposed on the tube body. The heating wire is powered on to generate heat, and the tube body transfers part of the heat to the aerosol matrix A through heat conduction and part of the heat is used to heat the air through the heat exchange core 232 to form a hot air flow.

[0055] Further, the heat exchange core 232 is provided with a plurality of through-hole structures, and the through-hole structures penetrate the heat exchange core 232 along the direction from the second opening 222 to the first opening 221. Specifically, the axis of the through-hole structure is a straight line along the direction from the second opening 222 to the first opening 221, and the through-hole structure is a straight-through structure, enabling the smooth flow of the hot air flow. At the same time, the residues in the heating channel 220 can also flow through the through-hole structures to the second opening 222 and flow into the liquid collecting member 240 through the second opening 222. The setting of the straight-through structure can reduce the possibility of residues remaining in the heat exchange core 232 and improve the collection effect of the residues.

[0056] Please refer to Figure 3 and Figure 4, a plurality of protruding structures 2111 are provided inside the first pipe body 211, and the plurality of protruding structures 2111 are arranged at intervals, forming partial air flow channels 250 between two adjacent protruding structures 2111. External air enters the interior of the heater 200 from the gaps between the protruding structures 2111.

[0057] Please refer to Figure 3 , the air flow channel 250 includes a first intake section 251, intake holes 252, a second intake section 253, and a third intake section 254. The first intake section 251 is formed between two adjacent protruding structures 2111. The intake holes 252 are provided through the side wall of the first pipe body 211. The second intake section 253 is arranged between the first pipe body 211 and the second pipe body 212. The first intake section 251 and the second intake section 253 are communicated through the intake holes 252. A third intake section 254 is formed between the second pipe body 212, the heating pipe 231, and the liquid collecting member 240, and the third intake section 254 is communicated with the second intake section 253.

[0058] During use, air enters the heater 200 from the first opening 221 in a top-intake manner, successively passes through the first intake section 251, the intake holes 252, the second intake section 253, and the third intake section 254, and then enters the through-hole structure through the second opening 222 (as Figure 3 shown by the arrow in the figure as the air flow direction). When passing through the through-hole structure, it is heated into hot air flow, and then flows into the aerosol matrix A along the heating channel 220 to heat the aerosol matrix A. Since the protruding structure 2111 abuts against the aerosol matrix A, the aerosol matrix A can be limited, so that the aerosol matrix A can be installed in the center, that is, coaxially arranged with the first pipe body 211 and the second pipe body 212, making the air around the aerosol matrix A uniform. When heating, the aerosol matrix A can be uniformly heated, avoiding uneven heating from affecting the use taste. At the same time, due to the layout of the positions of the heating channel 220, the air flow channel 250, and the liquid collecting member 240, the residual liquid flows into the liquid collecting member 240 to be collected and stored, and will not flow into the air flow channel 250 randomly.

[0059] Since the first intake section 251 is formed in the first pipe body 211, and this first intake section 251 partially overlaps with the heating channel 220, air entering from the first opening 221 can effectively utilize the space of the heater 200, making its structure compact.

[0060] Further, there are a plurality of air inlets 252, and the plurality of air inlets 252 are uniformly arranged around the axis of the first tube body 211. At least one air inlet 252 is correspondingly provided in each first air inlet section 251 formed between two adjacent convex structures 2111, so that air can flow into the heater 200 evenly. Eventually, the hot air flow around the circumference of the aerosol matrix A is uniform, ensuring that the aerosol matrix A is heated evenly, avoiding insufficient heating in the areas with less hot air flow and the generation of burnt smell due to excessive temperature in the areas with more hot air flow, thereby improving the use taste.

[0061] Of course, in other embodiments, the air flow channel 250 can also be formed between the first tube body 211 and the second tube body 212. The first tube body 211 and the second tube body 212 are in clearance fit or an air inlet structure is provided between the first tube body 211 and the second tube body 212 to form the air flow channel 250. The air flow channel 250 communicates with the heating channel 220 through the second opening 222, and air directly enters the heating channel along the air flow channel 250 and is heated by the heating component 230 into a hot air flow.

[0062] The above uses specific examples to elaborate on the present application, which is only used to help understand the present application and is not intended to limit the present application.
