Description

Technical Field

[0001] The present application relates to the technical field of aerosol generation, and more specifically, to a heating structure and a heat-not-burn device. Background Art

[0002] The heat-not-burn device uses a heating mechanism to heat and bake an aerosol substrate to generate an aerosol for a user to inhale. During an inhalation gap, the generated aerosol may flow back to other components or remain in the heating tube. After the temperature drops, the aerosol will condense to form condensate, which remains in the heat-not-burn device, not only causing waste of the aerosol but also polluting other components of the heat-not-burn device. For example, the condensate remains in the airway, causing an unpleasant odor when the user inhales and posing a risk of blocking the airway, resulting in a poor user experience.

Similar elements in different implementation manners are labeled with related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive descriptions. 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.

[0026] 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 an obvious manner for those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment, and do not mean that they are essential components and / or sequences.

[0027] The serial numbers assigned to the components in this article itself, 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 connections (couplings).

[0028] Please refer to Figures 1 to 6 , the present application provides a heat-not-burn device, including a heating structure 200 and a power supply assembly 300. The power supply assembly 300 is electrically connected to the heating structure 200 and is used to provide the power required for the heating structure 200 to operate.

[0029] The power supply assembly 300 further includes a housing assembly 100. There is a space in the housing assembly 100 for accommodating the power supply assembly 300 and the heating structure 200. At the same time, a switch button (not shown in the figure) for operating the heating structure 200 is provided on the housing assembly 100. The housing assembly 100 can form the outer contour of the entire heat-not-burn device, facilitating the user to carry, transport or operate the heat-not-burn device.

[0030] Please refer to Figures 1 to 3 , the heating structure 200 includes a heating tube 210, a storage member 220 and a second heating element 230. The heating tube 210 is used to heat the aerosol matrix A. The storage member 220 collects and stores the liquid in the heating chamber 214. The second heating element 230 is used to heat the liquid in the storage member 220. The liquid is the condensate formed by the condensation of the aerosol. Through the second heating element 230, the condensate can be heated to form an aerosol for the user to use again, achieving the effect of self-cleaning of the condensate and avoiding energy loss. Since the condensate can flow to other components of the heat-not-burn device, such as the power supply assembly 300, corroding or damaging the circuit of the power supply assembly 300 and affecting the normal operation of the heat-not-burn device, by heating the condensate with the second heating element 230 to vaporize it into an aerosol, it can avoid the condensate from polluting or damaging the entire heat-not-burn device, and can also avoid the condensate from blocking the airway or remaining on the airway to generate odors, affecting the user's taste.

[0031] Please refer to Figure 2 , the heating tube 210 has a first end 212 and a second end 213 which are oppositely arranged along its length direction. The first end 212 is used for the aerosol matrix A to be inserted. The heating tube 210 has a heating chamber 214 for accommodating the aerosol matrix A. A first heating element 211 is provided on the heating tube 210 for heating the aerosol matrix A. The storage member 220 is arranged at the second end 213, and the aerosol matrix A abuts against the storage member 220. Through the storage member 220, not only can the liquid be collected and stored, but also the insertion depth of the aerosol matrix A can be limited.

[0032] When in use, the user inserts the aerosol matrix A into the heating cavity 214, activates the first heating element 211 to heat the aerosol matrix A to form an aerosol. The aerosol is sucked and used by the user along the flow path from the second end 213 to the first end 212. During the suction gap, part of the aerosol remains in the heating cavity 214. After the first heating element 211 stops working for a period of time, the temperature inside the heat-not-burn device decreases, and the remaining aerosol condenses into a liquid. The liquid flows in the reverse direction from the first end 212 to the second end 213 and is stored in the storage member. When used again, the liquid can be vaporized into an aerosol for the user to use by activating the second heating element 230. The power supply assembly 300 is electrically connected to the first heating element 211 and the second heating element 230, and is used to provide the working power for the first heating element 211 and the second heating element 230.

[0033] In one embodiment, the second heating element 230 is disposed on the storage member 220, and the storage member 220 is disposed at the second end 213 of the heating tube 210 and is in sealed abutment with the second end 213. The second heating element 230 can be disposed around the outside of the storage member 220 or inside the storage member 220, and heats the liquid in the circumferential direction and / or the axial direction of the storage member 220. The second heating element 230 can be a heating wire, a heating sheet, a heating block or other structures, and can form an integrated structure with the storage member 220, reducing the number of assembled parts, simplifying the assembly, and improving the assembly efficiency.

[0034] In one embodiment, please refer to Figure 6 , the second heating element 230 is disposed on the heating tube 210, and the first heating element 211 and the second heating element 230 are arranged along the length direction of the heating tube 210. During assembly, the storage member 220 is nested inside the heating tube 210, at least part of the structure of the storage member 220 is in the heating cavity 214. The heating cavity 214 corresponding to the area where the first heating element 211 is disposed is used to heat the aerosol matrix A, and the heating cavity 214 corresponding to the area where the second heating element 230 is disposed is used to heat the liquid in the storage member 220. The pore 221 of the storage member 220 is completely disposed in the heating cavity 214, so that the liquid in the entire pore 221 can be heated and vaporized. Both the first heating element 211 and the second heating element 230 can be heating coatings formed on the heating tube 210 or heating wires (heating strips or heating coils) disposed around the heating tube 210.

[0035] In one embodiment, the first heating element 211 and the second heating element 230 are disposed on the outside of the heating tube 210. The heating tube 210 is made of a glass-ceramics material into a tubular structure, and its structure adapts to the shape of the aerosol matrix A. The first heating element 211 and the second heating element 230 disposed thereon are made of a conductive metal material, such as gold, silver, copper, chromium-nickel alloy, chromium-nickel-iron alloy, iron-chromium-aluminum alloy, iron-aluminum alloy or tungsten metal and other materials.

[0036] Please refer to Figure 4 and 5 Inside the storage member 220, there are provided a plurality of channels 221. The storage member 220 is made of ceramic or metal material, and the storage member 220 has good heat conduction performance and can effectively heat the liquid. The plurality of channels 221 provided on the storage member 220 can fully adsorb the liquid in the heating chamber 214 by means of capillary action, avoiding the liquid remaining in the heating chamber 214.

[0037] In one embodiment, the plurality of channels 221 are all arranged to extend along the direction from the first end 212 to the second end 213, and the central axes of the plurality of channels 221 are all straight lines, so that the flow path of the liquid is a straight line, facilitating the collection of the liquid, avoiding the obstruction to the liquid flow when the channels 221 are arranged in a zigzag manner, and also avoiding the aerosol formed by the gasification of the liquid remaining when flowing through the zigzag channels 221, effectively ensuring the cleaning effect of the liquid.

[0038] Please refer to Figure 4 In one embodiment, the channel 221 includes an open end 2211 and a closed end 2212. The open end 2211 is arranged close to the first end 212, and the closed end 2212 is arranged far from the first end 212. The liquid can enter through the open end 2211 and form a seal through the closed end 2212, avoiding the condensate flowing to other components, thereby storing the liquid in the channel 221.

[0039] Please refer to Figure 5 In another embodiment, the plurality of channels 221 are through-hole structures arranged to extend along the direction from the first end 212 to the second end 213. In order to avoid liquid leakage, the heating structure 200 further includes a seal 240. The seal 240 is arranged on the side of the storage member 220 far from the first end 212. The seal 240 is used to seal the channels 221. After the liquid flows into the channels 221, the seal 240 provided on one side of it is used for sealing, avoiding the condensate flowing to other components, thereby storing the liquid in the channels 221. The seal 240 is made of silicone material or can also be made of PEEK material. The seal 240 has high temperature resistance, avoiding the failure of the function of the seal 240 due to high temperature when the heat-not-burn device is in use. The seal 240 can not only seal the liquid in the channels 221 but also perform gas sealing, avoiding the leakage of the air flow inside the heat-not-burn device from affecting its normal operation.

[0040] In one embodiment, the second heating element 230 can also be arranged on the seal 240 and can heat the liquid in the channels 221 axially.

[0041] In one embodiment, the cross-section of the channel 221 is circular or polygonal, such as a hexagonal or pentagonal structure, etc., which is not limited herein. A plurality of channels 221 are uniformly arranged along the circumference of the entire storage member 220, and can form a honeycomb structure, so that the liquid is evenly distributed, and the liquid can also be evenly heated during heating, avoiding liquid residue.

[0042] Please refer to Figure 2 and Figure 3 , the heating structure 200 further includes a protective sleeve 250. The heating tube 210 is disposed inside the protective sleeve 250. The protective sleeve 250 is used to support and fix the heating tube 210. At the same time, the protective sleeve 250 also has heat insulation performance, which can reduce the heat loss on the heating tube 210 and improve the heating efficiency. A plurality of convex structures 251 are provided on the protective sleeve 250. The plurality of convex structures 251 are spaced apart to form air inlet holes 252 between two adjacent convex structures 251. The air inlet holes 252 communicate with the heating cavity 214, so that air flow enters the heating cavity 214 through the air inlet holes 252.

[0043] In one embodiment, the convex structure 251 is disposed near the first end 212. The plurality of convex structures 251 can also form a positioning structure for the aerosol matrix A. After the aerosol matrix A is inserted into the heating cavity 214 from the first end 212, the side surface contacts the convex structure 251. The plurality of convex structures 251 are spaced apart and uniformly arranged, so that the aerosol matrix A can be inserted in a centered manner, which facilitates the positioning of the aerosol matrix A and also makes the air flow around the aerosol matrix A uniform, thereby enabling the aerosol matrix A to be evenly heated and avoiding the situation of incomplete heating or burnt smell caused by excessive heating temperature due to uneven heating.

[0044] In one embodiment, the positioning structure formed by the convex structure 251 can be integrally formed with the protective sleeve 250, which can reduce the number of parts and improve the assembly efficiency. The positioning structure formed by the convex structure 251 can also be separately provided from the protective sleeve 250, which facilitates the disassembly and cleaning and maintenance of the components.

[0045] In one embodiment, the storage member 220 has an air flow channel 222. The air inlet hole 252, the heating cavity 214 and the air flow channel 222 are sequentially communicated to form the air duct (or at least part of the air duct) of the heat-not-burn device. The aerosol matrix A and the heating tube 210 are arranged with a gap. After the air flow enters from the air inlet hole 252, it flows along the gap between the aerosol matrix A and the heating tube 210 to the air flow channel 222, and then flows from the air flow channel 222 to the aerosol matrix A for the user to suck and use. The air flow path is as Figure 1 shown by the arrow direction in. The channel 221 communicates with the air flow channel 222. The air flow channel 222 can also collect the liquid, and then adsorb and store it in the channel 221 through the capillary phenomenon of the channel 221.

[0046] The above uses specific examples to elaborate on this application, which is only used to help understand this application and is not intended to limit this application. For those skilled in the technical field to which this application pertains, based on the idea of this application, several simple deductions, deformations, or substitutions can also be made.
