However, in existing HNB appliances, the heating element is limited by its structural design, making it susceptible to damage from high temperatures during heating. This results in poor heating stability, affecting the atomization efficiency of the aerosol products and reducing the user experience. Utility Model Content

[0003] This application provides a heating element and an aerosol generating device, aiming to solve the technical problem of poor heating stability in HNB appliances.

[0004] Some embodiments of this application provide a heating element, including:

[0005] The receiving element is configured as an integral cylindrical structure with an inner cavity for inserting an aerosol article; and,

[0006] A heating element includes a body portion and an outlet portion. The body portion is embedded in the receiving member and surrounds the outer periphery of the inner cavity. One end of the outlet portion is connected to the body portion and embedded in the receiving member, and the other end of the outlet portion extends to the outside of the receiving member to conduct current. The body portion is used to generate heat around the outer periphery of the aerosol product when energized to atomize the aerosol product.

[0007] In some embodiments, the body portion includes at least one coil segment, and the lead-out portion includes at least two lead-out electrodes;

[0008] The axial direction of the coil segment is arranged along the axial direction of the receiving member, and the coil segment is spirally wrapped around the receiving member. The two lead electrodes are respectively connected to the beginning and end of the coil segment, and adjacent coil segments share one lead electrode.

[0009] In some embodiments, the coil segment includes a multi-turn coil;

[0010] Each turn of the coil has a width along the axial direction of the receiving member and a thickness along the radial direction of the receiving member, wherein the width of each turn of the coil is greater than the thickness of the coil.

[0011] In some embodiments, the coil segment is located close to the inner sidewall of the receiving member in the radial direction.

[0012] In some embodiments, the aerosol article has a sensor;

[0013] The coil segment is used to detect the insertion state of the aerosol product through the sensor when energized.

[0014] In some embodiments, the cross-sectional area of ​​the accommodating member is larger than the cross-sectional area of ​​the aerosol product, and an airflow channel is formed between the inner sidewall of the accommodating member and the outer sidewall of the aerosol product. The airflow channel extends from the top of the accommodating member to the bottom of the aerosol product, and the cross-section is perpendicular to the axial direction of the accommodating member.

[0015] In some embodiments, the heating element further includes a housing;

[0016] The receiving component is installed inside the housing. The top of the housing is provided with an insertion port that communicates with the inner cavity. The aerosol product is inserted into the inner cavity through the insertion port. An airflow gap is provided between the aerosol product and the housing at the insertion port position. The airflow gap communicates with the airflow channel.

[0017] In some embodiments, the cross-sectional shape of the receiving member and the insertion port is non-circular, and at least part of the inner sidewall of the receiving member is used to clamp the aerosol product, the cross-section being perpendicular to the axial direction of the receiving member.

[0018] In some embodiments, the heating element further includes a base and a support;

[0019] The base is connected to the side of the receiving member opposite to the insertion port. The base has a receiving groove communicating with the inner cavity. The support is connected to the inner wall of the base and located at the bottom of the receiving groove. The aerosol product is inserted into the receiving groove and abuts against the support.

[0020] Some embodiments of this application also provide an aerosol generating device, including:

[0021] The heating element described in any of the above embodiments;

Simultaneously, the receiving component can fix the main body, preventing it from colliding with the receiving component due to shaking. When the aerosol product is inserted into the receiving component, because the main body surrounds the outer periphery of the inner cavity, the current introduced into the main body through the lead-out portion can generate heat around the aerosol product, thereby uniformly and rapidly atomizing the aerosol product from all sides, improving the atomization efficiency of the aerosol product.

Detailed Implementation

[0038] The present application will be further described in detail below with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0039] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0040] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0041] In existing technologies, the heating elements of HNB (Heated Toy) appliances are generally formed using thick-film printing or assembly processes. Heating elements formed using thick-film printing are prone to problems such as wire breakage, corrosion, and oxidation under high temperatures because the heating element is a plated film. Heating elements formed using assembly processes are susceptible to gaps during assembly, leading to shaking and collisions during user operation. Therefore, heating elements in existing technologies are easily damaged, affecting the heating stability of the HNB appliance.

[0042] This application provides an aerosol generating device, such as... Figure 1 and Figure 2 As shown, the aerosol generating device may include a heating element 1, a power supply component 2, and a housing 3. The power supply component 2 is electrically connected to the heating element 1 to supply power to the heating element 1. Both the heating element 1 and the power supply component 2 are installed inside the housing 3. The power supply component 2 may include a circuit board 21 and a battery cell 22. The heating element 1 is electrically connected to the circuit board 21, and the circuit board 21 is electrically connected to the battery cell 22, allowing the battery cell 22 to supply power to the heating element 1 through the circuit board 21. Furthermore, the power supply component 2 may also include electronic components such as a controller, a charging interface, and a temperature sensor, all of which are electrically connected to the circuit board 21. For example, the controller can be used to control the heating power of the heating element 1, the charging interface can be used to connect an external power source to charge the battery cell 22, and the temperature sensor can be used to sense temperature changes when the user uses the aerosol generating device. Depending on the appearance design of the aerosol generating device, the housing 3 may be configured as a structure where the top cover and the body are detachably connected, or as a structure where the upper and lower housings are detachably connected. The shape of the housing 3 may be box-shaped, strip-shaped, or columnar. The housing 3 can be divided into multiple installation spaces by brackets, separators, and other components for mounting components such as the heating element 1 and the power supply assembly 2. A push-button switch electrically connected to the power supply assembly 2 can also be installed on the housing 3 to control the start / stop operation of the heating element 1. This application does not impose any special restrictions on the specific structure of the power supply assembly 2 and the housing 3.

[0043] It is understood that the aerosol generating device can be configured as a non-detachable integrated structure, i.e., the heating element 1 and the power supply component 2 are fixedly connected. Alternatively, the aerosol generating device can also be configured as a detachable split structure, i.e., the heating element 1 and the power supply component 2 are detachably connected, thereby allowing the heating element 1 to be disassembled for cleaning, or the power supply component 2 to be replaced to increase battery life. This application does not impose any special restrictions on the specific structural form of the aerosol generating device.

[0044] To improve the stability of HNB appliances during heating, this application also provides a heating element 1, such as... Figure 3 and Figure 4As shown, the heating element 1 may include a accommodating member 11 and a heating element 12. The accommodating member 11 is configured as an integral cylindrical structure with an inner cavity 111 for inserting the aerosol product 4. The heating element 12 may include a body portion 121 and an outlet portion 122. The body portion 121 is embedded in the accommodating member 11 and surrounds the outer periphery of the inner cavity 111. One end of the outlet portion 122 is connected to the body portion 121 and embedded in the accommodating member 11. The other end of the outlet portion 122 extends to the outside of the accommodating member 11 to conduct current. The body portion 121 is used to generate heat around the outer periphery of the aerosol product 4 when energized to atomize the aerosol product 4.

[0045] This application designs the receiving component 11 as an integral cylindrical structure with an inner cavity 111, allowing the aerosol product 4 to be assembled within the receiving component 11 by inserting it into the inner cavity 111, thus facilitating the user's use of the aerosol generation equipment. The body portion 121 of the heating element 12 is embedded within the receiving component 11, allowing the receiving component 11 to enclose the body portion 121, thereby protecting it from problems such as wire breakage, corrosion, and oxidation, extending the durability of the heating element 12, and improving the heating stability of the heating element 1. Simultaneously, the receiving component 11 also serves to fix the body portion 121, preventing it from colliding with the receiving component 11 due to shaking. When the aerosol product 4 is inserted into the receiving member 11, since the body part 121 surrounds the outer periphery of the inner cavity 111, the body part 121 can generate heat in the circumference of the aerosol product 4 after the current is introduced through the lead-out part 122, thereby making the aerosol product 4 uniformly and quickly atomized around its periphery, so as to improve the atomization efficiency of the aerosol product 4.

[0046] The material of the housing 11 can be a high-temperature resistant insulating material such as silicon dioxide, zirconium oxide, or glass, while the heating element 12 can be a high-temperature resistant conductive material such as nickel 50 alloy, nickel-chromium-aluminum alloy, or titanium. Alternatively, the heating element 12 can also be a material with a high temperature coefficient of resistance (TCR). This application does not impose any special restrictions on the specific materials of the housing 11 and the heating element 12. When manufacturing the heating element 1, the housing 11 and the heating element 12 can be cast in one step, that is, the pre-formed heating element 12 is first placed into the mold, then the material of the housing 11 is injected into the mold, and finally the heating element 12 and the housing 11 are sintered together at high temperature. Alternatively, the housing 11 and the heating element 12 can also be cast in two steps, that is, a portion of the housing 11 can be pre-formed, then the heating element 12 is assembled onto the pre-formed housing 11, and finally the heating element 12 and the remaining portion of the housing 11 are sintered together. This application does not impose any special restrictions on the molding method between the housing 11 and the heating element 12.

[0047] In some embodiments, such as Figure 4 and Figure 5 As shown, the main body 121 may include at least one coil segment 123, and the lead-out portion 122 may include at least two lead-out electrodes 124; the axial direction (aa axis) of the coil segment 123 is arranged along the axial direction (aa axis) of the receiving member 11, and the coil segment 123 is spirally wrapped around the receiving member 11; the two lead-out electrodes 124 are respectively connected to the beginning and end ends of the coil segment 123, and adjacent coil segments 123 share one lead-out electrode 124.

[0048] The body portion 121 is configured as a spiral coil structure, which makes the heat radiated from the body portion 121 into the inner cavity 111 more uniform, thereby allowing the aerosol product 4 to be heated more evenly and avoiding the problem of scorching caused by excessively high local temperatures. The body portion 121 may include multiple coil segments 123 to cover the heating requirements along the length of the aerosol product 4, and different coil segments 123 can also heat different parts of the aerosol product 4 with different powers, thereby improving atomization efficiency. Figure 5 As shown, the main body 121 may include an integrally wound helical coil, and the lead-out part 122 may include three lead-out electrodes 124. Two of the lead-out electrodes 124 are connected to the beginning and end of the helical coil, respectively, and the remaining lead-out electrode 124 is connected to the middle position of the helical coil. Thus, the three lead-out electrodes 124 divide the helical coil into two coil segments 123, and the two coil segments 123 share the lead-out electrode 124 at the middle position. The three lead-out electrodes 124 are electrically connected to the circuit board 21, which can reduce the number of lead-out electrodes 124 connected to the circuit board 21, thereby reducing the assembly difficulty of the heating element 1.

[0049] In other embodiments, the body portion 121 may further include a greater number of coil segments 123, and correspondingly, the lead-out portion 122 may further include a greater number of lead-out electrodes 124. The multiple coil segments 123 may also be configured as a split structure, with each coil segment 123 having a separate lead-out electrode 124 at both ends. This application does not impose any special limitations on the number of coil segments 123 and the number of lead-out electrodes 124 in the heating element 12. Furthermore, the lead-out electrodes 124 may be led out radially or axially along the receiving member 11. This application does not impose any special limitations on the lead-out direction of the lead-out electrodes 124. The shape of the body portion 121 disposed on the receiving member 11 is not limited to a spiral coil, such as... Figure 6 As shown, the body portion 121 can also be configured as a serpentine coil structure, with the serpentine coil embedded in the receiving member 11 and surrounding the outer periphery of the inner cavity 111. Alternatively, the body portion 121 can also be configured as a mesh coil structure. This application does not impose any special restrictions on the specific shape of the body portion 121.

[0050] In some embodiments, such as Figure 7 As shown, the coil segment 123 may include multiple coil turns 125; each coil turn 125 has a width w along the axial direction (aa axis) of the receiving member 11 and a thickness d along the radial direction of the receiving member 11, and the width w of each coil turn 125 is greater than the thickness d of the coil turn 125.

[0051] By setting the width w of coil 125 to be greater than the thickness d of coil 125, the heating area of ​​coil 125 facing the inner cavity 111 can be increased, thereby improving the atomization efficiency of aerosol product 4. For example, the cross-sectional shape of coil 125 can be set to flat, which can not only increase the heating area of ​​coil 125, but also increase the welding area of ​​coil 125, so that the lead electrode 124 can be more easily welded to coil 125. In other embodiments, the cross-sectional shape of coil 125 can also be set to circular. This application does not impose any special restrictions on the cross-sectional shape of coil 125.

[0052] Furthermore, in order to heat different parts of the aerosol product 4 with different power, the coils 125 in different coil segments 123 can also have different helical pitches. For example, the coil segment 123 near the top of the receiving member 11 can have denser coils 125, while the coil segment 123 near the bottom of the receiving member 11 can have sparser coils 125 to improve the atomization efficiency of the aerosol product 4. This application does not impose any special restrictions on the density of the coils 125 in the coil segment 123.

[0053] In some embodiments, such as Figure 7 As shown, coil segment 123 is close to the inner wall of accommodating member 11 in the radial direction.

[0054] When manufacturing the heating element 1, the coil segment 123 can be embedded in the housing 11 near the inner wall. When the main body 121 generates heat in the energized state, the heat can quickly pass through the inner wall of the housing 11 into the inner cavity 111, thereby reducing heat transfer loss and improving atomization efficiency. The side of the coil 125 facing the inner wall of the housing 11 is covered within the housing 11, providing a protective layer to prevent corrosion or oxidation of this side, thus improving the durability of the heating element 12.

[0055] In some embodiments, the aerosol article 4 may have a sensor (not shown); the coil segment 123 is used to detect the insertion state of the aerosol article 4 by means of the sensor when energized.

[0056] For example, the sensor can be a metal component or a magnetic component. Since the coil segment 123 generates a magnetic field when energized, the magnetic induction generated by the coil segment 123 can be used to detect whether the aerosol product 4 is inserted into the inner cavity 111. Therefore, the insertion and removal of the aerosol product 4 can be used to control the start or stop of the heating element 1, thereby realizing the function of automatic atomization or shutdown of the aerosol generating equipment.

[0057] In some embodiments, such as Figure 8 As shown, the cross-sectional area of ​​the accommodating member 11 is larger than that of the aerosol product 4. An airflow channel 112 is formed between the inner sidewall of the accommodating member 11 and the outer sidewall of the aerosol product 4. The airflow channel 112 extends from the top of the accommodating member 11 to the bottom of the aerosol product 4, and its cross-section is perpendicular to the axial direction (aa axis) of the accommodating member 11.

[0058] By placing the airflow channel 112 within the housing 11, the housing 11 eliminates the need for holes in its sidewalls, thus creating a sealed heating space. During the atomization process of the aerosol product 4, any liquid or solid impurities generated during atomization can remain within the inner cavity 111 of the housing 11, preventing leakage and contamination of other components of the aerosol generating equipment. Furthermore, when cleaning the heating element 1, only the inner cavity 111 of the housing 11 needs cleaning, without needing to clean other components of the aerosol generating equipment, thereby simplifying maintenance.

[0059] In some embodiments, such as Figure 4 and Figure 9 As shown, the heating element 1 may also include a housing 13; the receiving member 11 is installed inside the housing 13, and the top of the housing 13 is provided with an insertion port 131 communicating with the inner cavity 111. The aerosol product 4 is inserted into the inner cavity 111 through the insertion port 131, and an airflow gap 132 is provided between the aerosol product 4 and the housing 13 at the insertion port 131 position. The airflow gap 132 is communicating with the airflow channel 112.

[0060] Similarly, the cross-sectional area of ​​the insertion port 131 at the top of the outer casing 13 can also be set to be larger than the cross-sectional area of ​​the aerosol product 4, so that an airflow gap 132 is formed between the side wall of the insertion port 131 and the outer side wall of the aerosol product 4. When the user uses the aerosol generating device, external air can flow into the airflow channel 112 from the airflow gap 132 for heating and atomization of the aerosol product 4. At the same time, a protrusion 133 extending into the insertion port 131 at the top of the outer casing 13 can also be provided. On the one hand, the protrusion 133 can play an axial limiting role for the receiving member 11, and on the other hand, the protrusion 133 can also play a limiting and fixing role for the aerosol product 4. This application does not impose special restrictions on the specific structure of the outer casing 13.

[0061] In some embodiments, such as Figure 8 and Figure 9 As shown, the cross-sectional shape of the accommodating member 11 and the insertion port 131 can be set to be non-circular, and at least part of the inner sidewall of the accommodating member 11 can be used to clamp the aerosol product 4, with the cross-section perpendicular to the axis of the accommodating member 11.

[0062] For example, the cross-sectional shapes of the receiving member 11 and the insertion port 131 can both be elliptical. When the aerosol product 4 is inserted into the inner cavity 111 through the insertion port 131, the minor axis directions of the insertion port 131 and the inner cavity 111 can be used to clamp the aerosol product 4, while the major axis directions of the insertion port 131 and the inner cavity 111 can respectively form an airflow gap 132 and an airflow channel 112 with the aerosol product 4. The two protrusions 133 can be arranged along the major axis direction of the insertion port 131, thereby allowing the aerosol product 4 to be fixed in both the major and minor axis directions of the insertion port 131. In other embodiments, the cross-sectional shapes of the receiving member 11 and the insertion port 131 can also be rectangular, oblong, or triangular, etc. This application does not impose any special limitations on the specific cross-sectional shapes of the receiving member 11 and the insertion port 131.

[0063] In some embodiments, such as Figure 10 and Figure 11 As shown, the heating element 1 may also include a base 14 and a support 141; the base 14 is connected to the side of the receiving member 11 away from the insertion port 131, the base 14 has a receiving groove 142 communicating with the inner cavity 111, the support 141 is connected to the inner side wall of the base 14 and is located at the bottom of the receiving groove 142, and the aerosol product 4 is inserted into the receiving groove 142 and abuts against the support 141.

[0064] By providing a base 14 on the side of the receiving member 11 away from the insertion port 131, impurities generated during the atomization process of the aerosol product 4 can be retained in the base 14, thereby preventing impurity leakage and facilitating user cleaning of the heating element 1. When the aerosol product 4 is inserted into the receiving groove 142, a gap is formed between the aerosol product 4 and the bottom of the receiving groove 142 because the aerosol product 4 abuts against the support part 141, allowing external airflow to flow into the bottom of the aerosol product 4.

[0065] During atomization, such as Figure 11As shown, external air flows into the airflow channel 112 through the airflow gap 132. At this time, the external air is heated by the heating element 12, and simultaneously, the external air also lowers the temperature in the inner cavity 111. The temperature change in the inner cavity 111 can be used to detect the user's action of using the aerosol product 4. The heated external air continues to flow along the airflow channel 112 into the bottom of the receiving tank 142, and finally flows into the interior of the aerosol product 4 for further heating. Heating and atomizing the aerosol product 4 through hot airflow results in more uniform heating of the aerosol product 4.

[0066] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
