Abstract
Description
Technical Field
[0001] This application belongs to the field of aerosol generation technology, and more specifically, relates to a heating element and an aerosol generation device. Background Technology
[0002] Currently, atomizer wick heating elements typically consist of two parts: a cotton wick and a heating wire. These are usually assembled by either wrapping the heating wire around the cotton wick or vice versa. During atomization, the heating wire is susceptible to slight vibrations due to airflow and extreme temperature fluctuations, which can cause it to separate from the cotton wick. This prevents the aerosol generation matrix from being properly supplied to the surface of the heating wire, leading to dry burning and a burnt taste, and even shortening the lifespan of the heating wire. Utility Model Content
[0003] The purpose of this application is to provide a heating element and an aerosol generating device to solve the technical problem that cotton wick heating elements in the prior art easily cause a burnt taste.
[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a heating element for heating the matrix of atomized aerosol generation, the heating element comprising:
[0005] Liquid guiding layer;

[0009] In some embodiments, the connector binds the liquid-conducting layer and the heating layer together in a manner that extends through the interior of the liquid-conducting layer and the interior of the heating layer.
[0010] In some embodiments, the connector has a liquid-guiding function and passes through the low-temperature zone of the heating layer.
[0011] In some embodiments, the connector binds the liquid-conducting layer and the heating layer together by wrapping around the outer surface of the liquid-conducting layer and the outer surface of the heating layer.

[0016] The heating layer includes two electrode sections and a heating section connected between the two electrode sections. The heating section is a heating mesh, a heating wire, or a heating film.
[0017] On the other hand, this application also provides an aerosol generating device, including the aforementioned heating element.
[0018] The beneficial effects of the heating element and aerosol generating device provided in this application are as follows: by setting a connector, the liquid guiding layer and the heating layer are connected as one unit, thereby improving the tightness and strength of the connection between the heating layer and the liquid guiding layer, preventing the heating layer from detaching from the liquid guiding layer during atomization, thus ensuring that the liquid guiding layer can continuously and stably supply liquid to the heating layer, thereby avoiding the problem of burnt taste caused by dry burning of the heating layer, and also improving the service life of the heating layer and even the heating element.

[0026] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0027] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

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.
[0029] 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 one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0030] As described in the background section, during the atomization process, the heating wire is easily affected by airflow, high and low temperature impacts, etc., causing it to vibrate slightly continuously. This leads to the separation of the heating wire from the cotton core, preventing the aerosol generation matrix from being properly supplied from the cotton core to the surface of the heating wire. Consequently, the heating wire burns dry, resulting in a scorched taste and even a short lifespan for the heating wire.
[0031] To address the aforementioned issues, this application provides a heating element 1 and an aerosol generating device. By additionally providing a connector 300, the liquid guiding layer 100 and the heating layer 200 are connected as a whole. This improves the tightness and strength of the connection between the heating layer 200 and the liquid guiding layer 100, preventing the heating layer 200 from detaching from the liquid guiding layer 100 during atomization. This ensures that the liquid guiding layer 100 can continuously and stably supply liquid to the heating layer 200, thereby avoiding the problem of burnt taste caused by dry burning of the heating layer 200. It also extends the service life of the heating layer 200 and even the heating element 1.
[0032] Please see Figure 1 and Figure 2 The heating element 1 provided in the embodiments of this application will now be described. This heating element 1 is used to heat and atomize an aerosol generating matrix to generate an aerosol. The aerosol generating matrix can be a liquid matrix or a solid matrix.
[0033] The heating element 1 includes a liquid-conducting layer 100, a heating layer 200, and a connector 300. The heating layer 200 is in fluid communication with the liquid-conducting layer 100; the connector 300 is used to connect the heating layer 200 and the liquid-conducting layer 100 into one unit.
[0034] The liquid-guiding layer 100 has a porous structure and possesses the capabilities of guiding, storing, and locking liquid. It has an absorption surface 110 and an atomizing surface 120. The absorption surface 110 is in fluid communication with the storage chamber of the aerosol generating device, and the atomizing surface 120 is in fluid communication with the heating layer 200. The liquid-guiding layer 100 absorbs and stores the aerosol generating matrix from the storage chamber. It also provides a continuous and stable liquid supply to the heating layer 200, which heats and atomizes the aerosol generating matrix to form an aerosol.
[0035] It should be noted that the heating layer 200 and the liquid guiding layer 100 are in fluid communication. This can be achieved by the heating layer 200 and the liquid guiding layer 100 being directly bonded and connected, or by the heating layer 200 and the liquid guiding layer 100 being connected through other liquid guiding components. For example, the connector 300 is located between the heating layer 200 and the liquid guiding layer 100, and the connector 300 is a liquid guiding structure.
[0036] It should also be noted that the connector 300 is used to connect the heating layer 200 and the liquid guiding layer 100 into a single unit. This means that the connector 300 connects the heating layer 200 and the liquid guiding layer 100, keeping them relatively fixed to form a whole. For example, the heating layer 200 can be kept attached to the liquid guiding layer 100, or the heating layer 200 and the liquid guiding layer 100 can be kept attached to opposite sides of the connector 300. This allows the heating layer 200 and the liquid guiding layer 100 to be transported and assembled as a whole, making them difficult to separate. Furthermore, it should be noted that the connection of the heating layer 200 and the liquid guiding layer 100 into a single unit can mean a connection that is difficult to separate without damaging the structure, or a connection that can be separated by fastening or unfastening.
[0037] In this embodiment, the heating element 1 is connected to the liquid guiding layer 100 and the heating layer 200 by means of a connector 300. This improves the tightness and strength of the connection between the heating layer 200 and the liquid guiding layer 100, increases the adhesion between them, and prevents them from separating momentarily during atomization. This ensures that the liquid guiding layer 100 can continuously and stably supply liquid to the heating layer 200, reduces the frequency of dry burning of the heating layer 200, and avoids the problem of burnt taste caused by dry burning of the heating layer 200. It also improves the service life of the heating layer 200 and even the heating element 1.
[0038] In some embodiments, the connector 300 can guide the aerosol generation matrix in the liquid guiding layer 100 to the heating layer 200. That is, the connector 300 can not only connect the heating layer 200 and the liquid guiding layer 100 into one unit, but also guide the aerosol generation matrix in the liquid guiding layer 100 to the heating layer 200. Through the continuous supply of liquid to the heating layer 200 by the liquid guiding layer 100 and the connector 300, the aerosol generation matrix on the surface of the heating layer 200 is increased, thereby preventing the heating layer 200 from dry burning.
[0039] Specifically, the connector 300 has tiny gaps or pores, allowing it to guide the aerosol-generating matrix in the liquid-conducting layer 100 to the heating layer 200 through capillary action. This also gives the connector 300 a certain degree of liquid-locking capability, preventing leakage from the heating layer 200 due to the added aerosol-generating matrix on its surface.
[0040] In some embodiments, please refer to Figures 1 to 4 The heating layer 200 is attached to the liquid guiding layer 100, and the connector 300 is used to bind the heating layer 200 and the liquid guiding layer 100 together.
[0041] Specifically, the connector 300 is used to bind the heating layer 200 and the liquid guiding layer 100 together. This means that the connector 300 shuttles back and forth or wraps around the heating layer 200 and the liquid guiding layer 100 multiple times, so that the heating layer 200 and the liquid guiding layer 100 are tightly bound and adhered together by the connector 300.
[0042] In this embodiment, the interconnected connection not only binds the heating layer 200 and the liquid guiding layer 100 together, greatly reducing the risk of separation, but also avoids affecting their structure. Furthermore, the connector 300 does not affect the liquid supply capacity of the liquid guiding layer 100 to the heating layer 200; in fact, when the connector 300 has liquid guiding capabilities, it can supply liquid to the heating layer 200. Moreover, the connector 300 does not affect the heating and atomization capability of the heating layer 200 for the aerosol generation matrix.
[0043] In this application, the connector 300 can bind the heating layer 200 and the liquid guiding layer 100 together in various ways. Furthermore, the connector 300 can also connect the heating layer 200 and the liquid guiding layer 100 into a single unit in other ways, which will be described in detail below through several embodiments.
[0044] Example 1:
[0045] Please see Figure 1 and Figure 2 The connector 300 binds the liquid-conducting layer 100 and the heating layer 200 together by penetrating the interior of the liquid-conducting layer 100 and the interior of the heating layer 200, so that the heating layer 200 and the liquid-conducting layer 100 are tightly attached.
[0046] Specifically, the liquid guiding layer 100 has a liquid absorbing surface 110 and an atomizing surface 120 arranged opposite to each other, and the heating layer 200 has a liquid-facing surface 240 and a liquid-returning surface 230 arranged opposite to each other. The liquid absorbing surface 110 is connected to the liquid storage cavity, the liquid-facing surface 240 of the heating layer 200 is attached to the atomizing surface 120 of the liquid guiding layer 100, and the liquid-returning surface 230 of the heating layer 200 is away from the atomizing surface 120.
[0047] When braiding the connector 300, the connector 300 can be wound from a first position on the liquid-absorbing surface 110 of the liquid-conducting layer 100, passing through the interior of the liquid-conducting layer 100 and the interior of the heating layer 200, to the back liquid-conducting surface 230 of the heating layer 200; then, from a second position on the back liquid-conducting surface 230 of the heating layer 200, passing through the interior of the heating layer 200 and the interior of the liquid-conducting layer 100, to the liquid-absorbing surface 110 of the liquid-conducting layer 100; then, from a third position on the liquid-conducting layer 100, passing through the interior of the heating layer 200 and the interior of the liquid-conducting layer 100, to the liquid-absorbing surface 110 of the liquid-conducting layer 100; and so on, until the heating layer 200 and the liquid-conducting layer 100 are securely bound together. It should be noted that the projections of the first, second, and third positions onto the liquid-absorbing surface 110 are staggered.
[0048] In this embodiment, the connector 300 binds the liquid-conducting layer 100 and the heating layer 200 together by penetrating the interior of both layers. This further enhances the connection strength between the liquid-conducting layer 100 and the heating layer 200 without affecting their shapes. Furthermore, when the connector 300 has both liquid-conducting and liquid-locking capabilities, it can also directly guide the aerosol-generating matrix in the liquid-conducting layer 100 to the heating layer 200 to meet the liquid supply requirements of the heating layer 200.
[0049] In this embodiment, the connector 300 is a flexible linear structure. The flexible linear structure passes through and wraps around the interior of the liquid guiding layer 100 and the interior of the heating layer 200 in sequence. This not only allows the connected connector 300 to fit as closely as possible to the liquid guiding layer 100 and the heating layer 200 after being wrapped, but also reduces the damage to the interior of the liquid guiding layer 100 and the heating layer 200 caused by the connector 300.
[0050] In this embodiment, the connector 300 is made of flexible fiber rope. The flexible fiber rope not only has good flexibility, allowing it to easily penetrate and bind the liquid-conducting layer 100 and the heating layer 200, but also has good structural strength, ensuring a secure binding of the liquid-conducting layer 100 and the heating layer 200. Furthermore, the flexible fiber layer can be made by winding various fibers, and the flexible fiber rope can be made by winding multiple strands of fiber rope, resulting in tiny gaps or holes in the flexible fiber rope. This gives the flexible fiber rope liquid-conducting capability, guiding the aerosol generation matrix inside the liquid-conducting layer 100 to the heating layer 200, thereby reducing the risk of the heating layer 200 burning out. Understandably, in other embodiments of this application, the connector 300 can also be made of other natural or synthetic fibers such as flax fiber, cotton fiber, viscose fiber, and polyimide fiber, which can guide the aerosol generation matrix and contact the atomization of the heating layer 200.
[0051] In this embodiment, the liquid guiding layer 100 is made of cotton fiber material, which gives it good liquid absorption, storage, and guiding properties, enabling it to effectively transport the aerosol generation matrix to the heating layer 200 and ensuring a stable atomization effect. It is understood that in other embodiments of this application, the liquid guiding layer 100 may also be a porous structure made of other materials, such as porous ceramic materials.
[0052] In this embodiment, the liquid-conducting layer 100 is flat and has an absorbent surface 110 and an atomizing surface 120 disposed opposite to each other. The heating layer 200 is attached to the atomizing surface 120 of the liquid-conducting layer 100 and is bound together with each other by flexible fiber ropes. It can be understood that in other embodiments of this application, the liquid-conducting layer 100 may also be cylindrical, and the heating layer 200 may be attached to the inner or outer circumferential surface of the liquid-conducting layer 100.
[0053] In this embodiment, please refer to Figure 1 The heating layer 200 includes two electrode portions 210 and a heating portion 220 connected between the two electrode portions 210. Both the two electrode portions 210 and the heating portion 220 are attached to the atomizing surface 120 of the liquid guiding layer 100. The two electrode portions 210 are respectively electrically connected to the power supply structure of the aerosol generating device, thereby supplying power to the heating portion 220. When energized, the heating portion 220 heats up to atomize the aerosol generating matrix and generate aerosol.
[0054] In this embodiment, the heating element 220 is a heating mesh, and the connector 300 passes through the hollowed-out position of the heating element 220. By using a heating mesh for the heating element 220, not only is the heating uniform throughout the heating element 220, but the flexible fiber rope can also be threaded through the hollowed-out position when winding it. This facilitates the fabrication of the flexible fiber rope and allows the aerosol generation matrix to be guided into the heating element 220 through the flexible fiber rope, resulting in better liquid supply. It is understood that in other embodiments of this application, the heating layer 200 may also include two electrode parts 210 and a heating wire or heating film connecting the two electrode parts 210; this is not a unique limitation.
[0055] In this embodiment, the winding density of the connector 300 can be set according to the actual mutual binding requirements and liquid guiding requirements. Furthermore, a single connector 300 can be continuously braided and wound on the heating layer 200 and the liquid guiding layer 100, or multiple connectors 300 can be provided, with each connector 300 sequentially distributed along the longitudinal direction of the liquid guiding layer 100, or sequentially distributed along the transverse direction of the liquid guiding layer 100, or sequentially distributed along the diagonal direction of the liquid guiding layer 100. For example... Figure 1In the middle, there are three connectors 300. The three connectors 300 are distributed sequentially along the longitudinal direction of the liquid guiding layer 100. Each connector 300 is woven and wound sequentially through the liquid guiding layer 100, the heating layer 200, the liquid guiding layer 100, and so on along the transverse direction of the liquid guiding layer 100.
[0056] It should be noted that the two electrode sections 210 are distributed at intervals along the transverse direction of the liquid guiding layer 100. The transverse direction of the liquid guiding layer 100 is parallel to the atomization surface 120 of the liquid guiding layer 100. The longitudinal direction of the liquid guiding layer 100 is perpendicular to the transverse direction of the liquid guiding layer 100, and the longitudinal direction of the liquid guiding layer 100 is parallel to the atomization surface 120 of the liquid guiding layer 100.
[0057] In this embodiment, a flexible fiber layer can be woven between the liquid-conducting layer 100 and the heating layer 200 using precision embroidery equipment in conjunction with AI visual positioning.
[0058] Example 2:
[0059] In this embodiment, the material and shape of the liquid guiding layer 100, the material and shape of the heating layer 200, and the material and shape of the connector 300 can be the same as in Embodiment 1. The difference is that in this embodiment, the connector 300 is further defined to have a liquid guiding function, and the connector 300 is inserted into the low-temperature zone of the heating layer 200. In this way, the connector 300 can supply liquid to the low-temperature zone of the heating layer 200, improve the atomization state of the heating layer 200 and the distribution of the temperature field of the atomization surface, enhance the design space of the heating layer 200, and obtain a better balance between taste, burst and lifespan.
[0060] For details, please refer to Figure 1 and Figure 2 The heating layer 200 includes two electrode portions 210 and a heating portion 220 connected between the two electrode portions 210. Both the two electrode portions 210 and the heating portion 220 are attached to the atomizing surface 120 of the liquid guiding layer 100. The heating portion 220 includes multiple V-shaped portions 221 and multiple linear portions 222. The two electrode portions 210 are spaced apart laterally along the liquid guiding layer 100. Linear portions 222 are connected to opposite sides of the V-shaped portions 221 along the longitudinal direction of the liquid guiding layer 100. Each V-shaped portion 221 is formed by multiple V-shaped structures 2211 sequentially connecting one electrode portion 210 to the other. The linear portions 222 include multiple linear structures 2221 located between the two electrode portions 210. Each linear structure 2221 extends longitudinally along the liquid guiding layer 100, and the three tips of each V-shaped structure 2211 are connected to different linear structures 2221.
[0061] Each line section 222 is a low-temperature zone. When the connector 300 is braided and wound, one connector 300 is provided for each low-temperature zone. Specifically, the connector 300 can pass through each line-like structure 2221 in the line section 222 in sequence along the transverse direction of the liquid guiding layer 100. It can be understood that in other embodiments of this application, the connector 300 can also be braided and wound every one or two line-like structures 2221. In addition, it is not necessary to provide a connector 300 for every line section 222. For example, a connector 300 can be provided for every other line section 222.
[0062] In this embodiment, please refer to Figure 1 The heating layer 200 is recessed inwards from the liquid-conducting layer 100 at both ends in the transverse direction, and also recessed inwards from the liquid-conducting layer 100 at both ends in the longitudinal direction. During winding, weaving can begin from one side of the liquid-conducting layer 100 located transversely outside the heating layer 200, and continue until weaving stops at the other side of the liquid-conducting layer 100 located transversely outside the heating layer 200, thereby improving the connection strength between the liquid-conducting layer 100 and the heating layer 200. It is understood that in other embodiments of this application, the connectors 300 can also be woven along the longitudinal direction of the liquid-conducting layer 100; this is not a limiting factor.
[0063] Example 3:
[0064] Please see Figure 3 and Figure 4 The connector 300 binds the liquid-conducting layer 100 and the heating layer 200 together by wrapping around the outer surfaces of the liquid-conducting layer 100 and the heating layer 200. Specifically, the connector 300 is wound from the liquid-absorbing surface 110 of the liquid-conducting layer 100 across one edge of the liquid-conducting layer 100 to the back liquid-absorbing surface 230 of the heating layer 200 away from the liquid-conducting layer 100; then, the connector 300 is wound from the back liquid-absorbing surface 230 of the heating layer 200 across the other edge of the liquid-conducting layer 100 to the liquid-absorbing surface 110 of the liquid-conducting layer 100; then, the connector 300 is wound from the liquid-absorbing surface 110 of the liquid-conducting layer 100 across the other edge of the liquid-conducting layer 100 to the back liquid-absorbing surface 230 of the heating layer 200, and this process is repeated until the heating layer 200 and the liquid-conducting layer 100 are securely bound together.
[0065] In this embodiment, please refer to Figure 3The connector 300 extends from the liquid-absorbing surface 110 of the liquid-conducting layer 100, across the upper edge of the liquid-conducting layer 100, and wraps around to the back liquid-repellent surface 230 of the heating layer 200 away from the liquid-conducting layer 100. It then extends from the outer surface of the heating layer 200, across the lower edge of the liquid-conducting layer 100, and wraps around to the liquid-absorbing surface 110 of the liquid-conducting layer 100. This process is repeated until the heating layer 200 and the liquid-conducting layer 100 are securely bound together. It should be noted that the upper edge of the liquid-conducting layer 100 refers to the edges of the liquid-conducting layer 100 along its longitudinal direction.
[0066] In this embodiment, please refer to Figure 3 The heating layer 200 also includes two electrode portions 210 and a heating portion 220 connected between the two electrode portions 210. Both the two electrode portions 210 and the heating portion 220 are attached to the atomizing surface 120 of the liquid guiding layer 100. The heating portion 220 is a heating mesh, including multiple V-shaped portions 221 and multiple linear portions 222. The two electrode portions 210 are spaced apart laterally along the liquid guiding layer 100. Linear portions 222 are connected to opposite sides of the V-shaped portions 221 along the longitudinal direction of the liquid guiding layer 100. Each V-shaped portion 221 is formed by multiple V-shaped structures 2211 sequentially connecting one electrode portion 210 to the other. Each linear portion 222 includes multiple linear structures 2221 located between the two electrode portions 210. Each linear structure 2221 extends longitudinally along the liquid guiding layer 100, and the three tips of each V-shaped structure 2211 are connected to different linear structures 2221. It is understood that in other embodiments of this application, the heating element 220 may also be a heating wire or a heating film, and this is not the only one.
[0067] In this embodiment, please refer to Figure 3 The heating element 220 includes a plurality of heating units connected sequentially along the transverse direction of the liquid guiding layer 100. Each heating unit includes a linear structure 2221, a V-shaped structure 2211, a linear structure 2221, a V-shaped structure 2211, and a linear structure 2221 connected sequentially along the longitudinal direction. When the connector 300 is wound, when the connector 300 is wound to the back liquid surface 230 of the heating layer 200, it is positioned at the connection position between the electrode part 210 and the heating unit, or at the connection position between two adjacent heating units. This allows the connector 300 to be at least partially confined in the gap between two adjacent linear structures 2221, which not only limits the connector 300 but also reduces the overlap area between the connector 300 and the heating layer 200.
[0068] In this embodiment, the connector 300 includes a flexible fiber rope. The flexible fiber rope not only possesses good flexibility, allowing it to easily wrap around and bind to the outer surfaces of the liquid-conducting layer 100 and the heating layer 200, but also has good structural strength, ensuring a secure binding of the liquid-conducting layer 100 and the heating layer 200. Furthermore, the flexible fiber layer can be made by winding various fiber materials, and the flexible fiber rope can be made by winding multiple strands of fiber rope. The flexible fiber rope has tiny gaps or holes, giving it liquid-conducting capabilities, enabling it to guide the aerosol-generating matrix inside the liquid-conducting layer 100 to the heating layer 200. It is understood that in other embodiments of this application, the connector 300 may also be made of other natural or synthetic fibers such as flax fiber, cotton fiber, viscose fiber, and polyimide fiber, which can guide the aerosol-generating matrix and contact the atomization of the heating layer 200.
[0069] In this embodiment, the liquid guiding layer 100 is made of cotton fiber material, which gives it good liquid absorption, storage, and guiding properties, enabling it to effectively transport the aerosol generation matrix to the heating layer 200 and ensuring a stable atomization effect. It is understood that in other embodiments of this application, the liquid guiding layer 100 may also be a porous structure made of other materials, such as porous ceramic materials.
[0070] In this embodiment, the liquid-conducting layer 100 is flat and has an absorbent surface 110 and an atomizing surface 120 disposed opposite to each other. The heating layer 200 is attached to the atomizing surface 120 of the liquid-conducting layer 100 and is bound together with each other by flexible fiber ropes. It can be understood that in other embodiments of this application, the liquid-conducting layer 100 may also be cylindrical, in which case the heating layer 200 may be attached to the inner or outer circumferential surface of the liquid-conducting layer 100.
[0071] Example 4:
[0072] In this embodiment, the connector 300 extends from the absorbent surface 110 of the liquid-conducting layer 100 across the left edge of the liquid-conducting layer 100 to the back liquid surface 230 of the heating layer 200 away from the liquid-conducting layer 100, and then extends from the back liquid surface 230 of the heating layer 200 across the right edge of the liquid-conducting layer 100 to the absorbent surface 110 of the liquid-conducting layer 100, repeating this winding process until the heating layer 200 and the liquid-conducting layer 100 are securely bound together. The left and right edges of the liquid-conducting layer 100 are the opposite lateral edges of the liquid-conducting layer 100. It is understood that in other embodiments of this application, the connector 300 may be wound in a direction inclined to the lateral direction of the liquid-conducting layer 100; this is not a unique limitation.
[0073] Example 5:
[0074] In this embodiment, the heating layer 200 is not directly attached to the liquid guiding layer 100. Instead, the heating layer 200 is attached to the liquid guiding layer 100 via a connector 300, which has a porous structure.
[0075] Specifically, the connector 300 is a porous high-temperature adhesive. This porous high-temperature adhesive bonds the liquid-conducting layer 100 to the heating layer 200, forming a connection between them. Simultaneously, because the connector 300 is a porous high-temperature adhesive, the aerosol matrix generated in the liquid-conducting layer 100 can be guided into the heating layer 200 via the porous high-temperature adhesive, ensuring a continuous and stable supply of liquid to the heating layer 200 from the liquid-conducting layer 100.
[0076] In this embodiment, the porous high-temperature adhesive can be a porous PI (Polyimide) adhesive or a porous silicone adhesive.
[0077] In this embodiment, the liquid-conducting layer 100 can be flat or cylindrical. The liquid-conducting layer 100 can be made of cotton fibers or porous ceramics.
[0078] In this embodiment, the heating layer 200 may include two electrode portions 210 and a heating portion 220, heating wire or heating film connected between the two electrode portions 210.
[0079] Example 6:
[0080] An inorganic slurry is used to create a porous layer on the surface of the heating layer 200, which improves the liquid supply capacity of the liquid-conducting layer 100 to the heating layer 200. It also possesses a certain degree of viscosity, enhancing the connection strength between the heating layer 200 and the liquid-conducting layer 100. Furthermore, the inorganic nanomaterials (such as carbon nanotubes and graphene) in the inorganic slurry have high electro-thermal radiation conversion efficiency, enabling rapid conversion of electrical energy into heat energy, thus facilitating rapid heat transfer and uniform distribution.
[0081] On the other hand, this application also provides an aerosol generating device, including the aforementioned heating element 1. The aerosol generating device provided in this application, by incorporating the heating element 1, can improve the inhalation experience of the aerosol generating device and also extend its service life.
[0082] In addition, the aerosol generating device also includes a liquid storage chamber and an airflow channel. The liquid absorption surface 110 of the liquid guiding layer 100 is in fluid communication with the liquid storage chamber, and the atomizing surface 120 of the liquid guiding layer 100 is in communication with the airflow channel. The liquid guiding layer 100 draws aerosol generating matrix from the liquid storage chamber and supplies it to the heating layer 200. After the heating layer 200 is powered on, it heats and atomizes the aerosol generating matrix to generate aerosol. The airflow in the airflow channel carries the aerosol out for the user to inhale.
[0083] The aerosol generating device also includes a main shell, an atomizing seat, and a power supply structure. The main shell forms a liquid storage chamber. The atomizing seat is connected to the main shell. The power supply structure is connected to the atomizing seat. The heating element 1 is installed on the atomizing seat. The power supply structure is electrically connected to the heating element 1. The airflow channel passes through the power supply structure, the atomizing seat, and the main shell.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
