Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to a heating component and a heating non-combustible device. Background Technology

[0002] Heated non-combustible devices, also known as low-temperature non-combustible heating devices, are electronic devices that heat herbal products (such as low-temperature non-combustible cigarettes) at low temperatures (generally 200-400°C) to form an inhalable aerosol. Compared with traditional combustible cigarettes, heated non-combustible devices operate at lower temperatures, and the harmful components in the aerosols they produce are far lower than those in traditional combustible cigarettes. Therefore, the use of heated non-combustible devices can greatly reduce the adverse effects of traditional cigarettes on the human body. Among them, the heating component containing the heating element, as the core component of heated non-combustible devices, has always been the focus of research in the field.

[0003] In related technologies, heating components typically employ either center heating or peripheral heating. Center heating involves inserting the heating component into the herbal product, using its heat to heat the product from the inside out. Peripheral heating involves surrounding the herbal product, using its heat to heat it from the outside in. Currently, commercially available center-heating components generally employ a metal resistance heating structure. This structure uses insulating ceramic as a substrate, on which metal heating circuitry is printed and then sintered at high temperatures to fix the circuitry to the substrate. When power is applied to the two ends of the heating circuitry, the heating component heats up and atomizes the herbal material, producing an aerosol for the user to inhale. However, this type of metal resistance heating component generally suffers from the following problems:

[0004] 1. Because heat is generated only on the metal heating circuit when energized, and the wire diameter of the metal heating circuit is usually relatively thin, the contact area with the insulating ceramic substrate is small, which leads to poor temperature field uniformity and low heating efficiency of the heating component.

[0005] 2. Due to the difference in thermal expansion coefficients between the metal heating circuit and the insulating ceramic substrate, the metal heating circuit is prone to detaching from the insulating ceramic substrate after prolonged and repeated high-temperature heating during later use, leading to the failure of the heating component. Utility Model Content

[0006] The main purpose of this utility model is to provide a heating component and a heating non-combustible device, which aims to improve the service life, temperature field uniformity and heating efficiency of the heating component.

[0007] To achieve the above objectives, this utility model provides a heating component for heating herbal products, the heating component comprising:

[0008] A first heating element, made of conductive ceramic material, is arranged to form a hollow through hole. The first heating element has a first end and a second end opposite to each other along its own axial direction, and a third end and a fourth end opposite to each other along its own circumference. There is a gap between the end face of the third end and the end face of the fourth end, forming an opening that communicates with the through hole. The opening extends along the axial direction of the first heating element from the end face of the first end to the end face of the second end, and the size of the opening is 0.2 mm to 1 mm. The outer diameter of the first heating element is 1.5 mm to 3 mm.

[0009] Furthermore, the first end is designed to be pointed.

[0010] Furthermore, the length of the first heating element is equal along its own circumference.

[0011] Furthermore, the heating assembly also includes an insulating part made of insulating material, which is connected to the first heating element.

[0012] Furthermore, the insulating portion fills the through hole, and the shapes of the two ends of the insulating portion along the axial direction of the first heating element correspond to the shapes of the first end and the second end of the first heating element, respectively.

[0013] Furthermore, when the length of the first heating element along its own circumference is equal, the insulating part is pointed and the insulating part is connected to the end face of the first end.

[0014] Furthermore, a heat-insulating part made of heat-insulating material is sandwiched between the outer peripheral wall of the insulating part and the inner peripheral wall of the first heating element.

[0015] Furthermore, the heating assembly also includes a protective part made of insulating and thermally conductive material. The protective part is a tubular structure with a wall thickness of 0.4 mm to 1.2 mm, and the inner peripheral wall of the protective part is in close contact with the outer peripheral wall of the first heating element.

[0016] Furthermore, the heating assembly also includes a base made of insulating material, with one end of the insulating part away from the first end protruding from the through hole and fixed inside the base, and the end face of the second end contacting or being spaced apart from the upper end face of the base.

[0017] Furthermore, the heating assembly also includes a first electrode terminal and a second electrode terminal spaced apart, as well as a first electrode lead and a second electrode lead spaced apart. The first electrode terminal and the second electrode terminal are both disposed at the bottom of the base. The lower end face of the first electrode terminal and the lower end face of the second electrode terminal are both exposed from the bottom surface of the base. The first electrode lead is electrically connected to the first heating element and the first electrode terminal, respectively, and the second electrode lead is electrically connected to the first heating element and the second electrode terminal, respectively.

[0018] Furthermore, the base has multiple heat-insulating gaps distributed within it, which at least serve to prevent the heat generated by the first heating element from being transferred to the bottom of the base.

[0019] Furthermore, the heating assembly also includes a second heating element and a base made of insulating material. The second heating element includes any one of a metal resistance heating tube, an infrared heating tube, an electromagnetic induction heating tube, and a cylindrical conductive ceramic heating tube. The lower ends of the first heating element and the second heating element are both fixedly connected to the base. The first heating element is located inside the second heating element, and the outer peripheral wall of the first heating element and the inner peripheral wall of the second heating element are spaced apart from each other.

[0020] Furthermore, the outer diameter of the first heating element is 1.8 mm to 2.6 mm.

[0021] Furthermore, the thickness of the first heating element is 0.1 mm to 2 mm.

[0022] Furthermore, the size of the slit is 0.3mm to 0.8mm.

[0023] Furthermore, the thickness of the first heating element is 0.2 mm to 1.5 mm.

[0024] Furthermore, the heating assembly also includes a first electrode lead and a second electrode lead, wherein the first electrode lead is electrically connected to the end face, inner wall surface or outer wall surface of the first end, and the second electrode lead is electrically connected to the end face, inner wall surface or outer wall surface of the second end.

[0025] Furthermore, the heating assembly also includes a first electrode lead and a second electrode lead, wherein the first electrode lead is electrically connected to the end face, inner wall surface or outer wall surface of the third end, and the second electrode lead is electrically connected to the end face, inner wall surface or outer wall surface of the fourth end.

[0026] To achieve the above objectives, this utility model also provides a heating non-combustible device, which includes a mounting housing, a battery assembly, and the aforementioned heating assembly. The heating assembly and the battery assembly are both installed inside the mounting housing. The upper end of the mounting housing is provided with a receiving cavity capable of accommodating herbal products. The first heating element is located inside the receiving cavity, and the battery assembly is electrically connected to the first heating element.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects:

[0028] 1. In the technical solution of this utility model, the first heating element is made of conductive ceramic material. After the first heating element is energized, it can generate heat as a whole. Compared with the traditional metal heating circuit, the first heating element is a tubular structure with slits, which has a larger heating area. This can improve the temperature field uniformity and heating efficiency of the heating component, and is conducive to fully and quickly heating the herbal product to the atomized state.

[0029] 2. Compared with traditional metal heating circuits printed on insulating ceramic substrates, the first heating element provided in this embodiment can exist independently without relying on other carriers. Therefore, there is no problem of the metal heating circuit falling off the insulating ceramic substrate and causing the heating component to fail, thereby effectively improving the service life of the heating component.

[0030] 3. In the technical solution of this utility model, by designing the first heating element as a tubular structure with slits, compared with designing the first heating element as a tubular structure without slits, the flexibility of the electrode lead-out method of the heating component can be improved. Specifically, in the later installation and use, the electrode leads can be set at both ends of the first heating element along its axial direction to ensure the heating effect of the first heating element, or the electrode leads can be set at both ends of the first heating element along its circumference to ensure the heating effect of the first heating element, instead of being limited to only setting the electrode leads at both ends of the first heating element along its axial direction to ensure the heating effect of the first heating element.

[0031] 4. By reasonably setting the slit size of the first heating element to 0.2mm to 1mm, firstly, it avoids increasing the processing difficulty of the first heating element if the slit is too small (less than 0.2mm); secondly, it avoids the problem of arcing between the two end faces of the first heating element along its circumference, which could lead to a short circuit; and thirdly, it avoids reducing the heating area and structural strength of the first heating element if the slit is too large (greater than 1mm). In other words, by reasonably setting the slit size of the first heating element to 0.2mm to 1mm, it not only reduces the processing difficulty of the first heating element, thus helping to reduce the processing cost, but also avoids the problem of short circuits during the heating process, thereby ensuring the working stability of the first heating element. In addition, it also ensures that the first heating element has sufficient heating area and structural strength, thus ensuring the heating efficiency and service life of the first heating element.

[0032] 5. By setting the outer diameter of the first heating element to 1.5mm to 3mm, the first heating element can be used to heat various types of herbal products currently on the market through center heating. Attached Figure Description

[0062] Please refer to Figure 1-5This utility model provides a heating assembly for heating herbal products. The heating assembly includes a first heating element 11 made of conductive ceramic material. The first heating element 11 surrounds and forms a hollow through-hole 1101. The first heating element 11 has opposing first ends 111 and second ends 112 along its axial direction, and opposing third ends 113 and fourth ends 114 along its circumference. A gap exists between the end faces of the third ends 113 and the fourth ends 114, forming a slit 1102 communicating with the through-hole 1101. The slit 1102 extends along the axial direction of the first heating element 11 from the end face of the first end 111 to the end face of the second end 112, and the size of the slit 1102 is 0.2mm to 1mm. The outer diameter of the first heating element 11 is 1.5mm to 3mm. (Illustrated example follows...) Figure 2 As shown, assuming the size of the slit 1102 is L and the outer diameter of the first heating element is D, then 0.2mm≤L≤1mm and 1.5mm≤D≤3mm.

[0063] In this embodiment, it should be noted that, in specific implementation, the size of the slit 1102 along the axial direction of the first heating body 11 (i.e., the length direction of the first heating body 11) can be uniformly or non-uniformly set; in addition, the size of the slit 1102 along the radial direction of the first heating body 11 can be uniformly or non-uniformly set; it can be flexibly set according to actual needs, as long as it can meet the usage requirements, and this embodiment does not impose specific restrictions on it.

[0064] In this embodiment, it is understood that, in specific implementation, the shape of the first heating element 11 can be a circular tube with a slit 1102 (at this time, the cross-section of the first heating element 11 can be a circle or ellipse with a notch), a square tube (at this time, the cross-section of the first heating element 11 can be a square or rectangle with a notch), a triangular tube (at this time, the cross-section of the first heating element 11 is a triangle with a notch), etc., which can be determined according to actual needs, and this embodiment does not impose specific limitations on it.

[0065] Based on the above structural design, the heating assembly provided in this embodiment has the following technical effects:

[0066] 1. The first heating element 11 of the first heating element 1 is made of conductive ceramic material. After the first heating element 11 is powered on, it can heat up as a whole. Compared with the traditional metal heating circuit, the first heating element 11 has a tubular structure with a slit 1102, which has a larger heating area, thereby improving the temperature field uniformity and heating efficiency of the heating component, which is conducive to fully and quickly heating the herbal product to the atomized state.

[0067] 2. Compared with traditional metal heating circuits printed on insulating ceramic substrates, the first heating element 11 provided in this embodiment can exist independently without relying on other carriers. Therefore, there is no problem of the metal heating circuit falling off the insulating ceramic substrate and causing the heating component to fail, thereby effectively improving the service life of the heating component.

[0068] 3. By designing the first heating element 11 as a tubular structure with slits 1102, compared to designing the first heating element 11 as a tubular structure without slits 1102, the flexibility of the electrode lead-out method of the heating assembly can be improved. Specifically, in later installation and use, the electrode leads can be set at both ends of the first heating element 11 along its axial direction to ensure the heating effect of the first heating element 11 (e.g., Figure 4-5 (As shown), alternatively, electrode leads can be positioned at both ends of the first heating element 11 along its circumference to ensure the heating effect of the first heating element 11 (e.g., Figure 3 As shown), it is not limited to only selecting to set the electrode leads at both ends of the first heating element 11 along its axial direction to ensure the heating effect of the first heating element 11.

[0069] 4. By reasonably setting the size of the slit 1102 of the first heating element 11 to 0.2mm to 1mm, firstly, it can avoid increasing the processing difficulty of the first heating element 11 if the slit 1102 is set too small (less than 0.2mm); secondly, it can avoid the problem of arcing between the two end faces of the first heating element 11 along its circumference and causing a short circuit if the slit 1102 is set too small (less than 0.2mm); thirdly, it can avoid reducing the efficiency of the first heating element 11 if the slit 1102 is set too large (greater than 1mm). The heating area and structural strength of the first heating element 11; that is, by reasonably setting the size of the slit 1102 of the first heating element 11 to 0.2mm to 1mm, not only can the processing difficulty of the first heating element 11 be reduced, thereby reducing the processing cost of the first heating element 11, but also the problem of short circuit during the heating process of the first heating element 11 can be avoided, thereby ensuring the working stability of the first heating element 11. In addition, it can also ensure that the first heating element 11 has sufficient heating area and structural strength, thereby ensuring the heating efficiency and service life of the first heating element 11. In specific implementation, in order to better balance the processing difficulty, working stability, heating area and structural strength of the first heating element 11, the size of the slit 1102 can be further set to 0.3mm to 0.8mm.

[0070] 5. In this embodiment, by setting the outer diameter of the first heating element 11 to 1.5mm to 3mm, the first heating element 11 can be used to heat various types of herbal products currently available on the market through center heating. It is understood that, in specific implementations, the specific size of the outer diameter of the first heating element 11 can be determined according to the size of the herbal product to be heated. For example, when the herbal product to be heated is a low-temperature non-combustible cigarette with a large outer diameter, the outer diameter of the first heating element 11 can be appropriately set larger within the range of 1.5 to 3mm; conversely, when the herbal product to be heated is a low-temperature non-combustible cigarette with a small outer diameter, the outer diameter of the first heating element 11 can be appropriately set smaller within the range of 1.5 to 3mm. As long as the herbal product can be heated through center heating, this embodiment does not impose specific limitations. In some optional embodiments, the outer diameter of the first heating element 11 can be further set to 1.8mm to 2.6mm, thus enabling the first heating element 11 to be used to heat common types of herbal products currently available on the market through center heating.

[0071] Further, please refer to Figure 1-2 In some optional embodiments of this utility model, the thickness of the first heating element 11 (i.e., the wall thickness of the first heating element 11) can be set to 0.1mm to 2mm, as illustrated in the figure. Figure 2 As shown, assuming the thickness of the first heating element 11 is T, then 0.1mm ≤ T ≤ 2mm. This setting serves two purposes: firstly, it avoids making the thickness of the first heating element 11 too thin (less than 0.1mm), which would reduce its structural strength and prevent cracking during heating due to insufficient structural strength, thus preventing a reduction in its service life; secondly, it avoids making the thickness of the first heating element 11 too thick (greater than 2mm), which would increase its heat capacity, thus reducing the heat capacity of the first heating element 11 and allowing it to heat up to the required temperature more quickly after being energized, thereby facilitating faster heating of the herbal product to an atomized state. Therefore, this embodiment, by reasonably setting the thickness of the first heating element 11 to 0.1–2mm, ensures both the structural strength of the first heating element 11, thereby further improving the service life of the heating assembly, and the heating efficiency of the first heating element 11, thus facilitating faster heating of the herbal product to an atomized state. In some preferred embodiments, in order to better balance the structural strength and heating efficiency of the first heating element 11, the thickness of the first heating element 11 can be further set to 0.2mm to 1.5mm.

[0072] Furthermore, in some optional embodiments of this utility model, in order to improve the heating effect of the first heating element 11, during subsequent installation and use, the electrode leads can be optionally disposed at both ends of the first heating element 11 along its axial direction. Specifically:

[0073] like Figure 4-5 As shown, the heating assembly also includes a first electrode lead 41 and a second electrode lead 42 spaced apart. The first electrode lead 41 can be electrically connected to the end face of the first end 111, or it can be electrically connected to the inner wall surface of the first end 111 (e.g., ...). Figure 5 As shown), it can also be electrically connected to the outer wall surface of the first end 111 (as shown). Figure 4 As shown), simultaneously, the second electrode lead 42 can be electrically connected to the end face of the second end 112, the inner wall surface of the second end 112, or the outer wall surface of the second end 112 (as shown). Figure 4 Or as shown in Figure 5). Exemplarily, in some alternative implementations, such as Figure 4 As shown, one end of the first electrode lead 41 is electrically connected to the outer wall surface of the first end 111 (specifically, one end of the first electrode lead 41 can be electrically connected to the outer wall surface at the junction of the first end 111 and the third end 113), while one end of the second electrode lead 42 is electrically connected to the outer wall surface of the second end 112 (specifically, one end of the second electrode lead 42 can be electrically connected to the outer wall surface at the junction of the second end 112 and the fourth end 114); in some other optional embodiments, such as Figure 5 As shown, one end of the first electrode lead 41 is electrically connected to the inner wall surface of the first end 111, while at the same time, one end of the second electrode lead 42 is electrically connected to the outer wall surface of the second end 112.

[0074] In this embodiment, based on the above structural design, when the first electrode lead 41 and the second electrode lead 42 are connected to an external power source (such as the battery assembly of a heating non-combustible device), the current can flow fully through the entire first heating body 11 along the axial direction, thereby enabling the first heating body 11 to obtain a good power-on heating effect.

[0075] Furthermore, in some optional embodiments of this utility model, in order to improve the heating effect of the first heating element 11, during subsequent installation and use, the electrode leads can be optionally disposed at both ends of the first heating element 11 along its circumference, specifically:

[0076] like Figure 3As shown, the heating assembly also includes a first electrode lead 41 and a second electrode lead 42 spaced apart. The first electrode lead 41 can be electrically connected to the end face of the third end 113, the inner wall surface of the third end 113, and the outer wall surface of the third end 113. Simultaneously, the second electrode lead 42 can be electrically connected to the end face of the fourth end 114, the inner wall surface of the fourth end 114, and the outer wall surface of the fourth end 114. For example, as... Figure 3 As shown, the upper end of the first electrode lead 41 is electrically connected to the outer wall surface of the third end 113 and the upper end of the first electrode lead 41 extends upward along the outer wall surface of the third end 113 to the first end 111. At the same time, the upper end of the second electrode lead 42 is electrically connected to the outer wall surface of the fourth end 114 and the upper end of the second electrode lead 42 extends upward along the outer wall surface of the fourth end 114 to the first end 111.

[0077] In this embodiment, based on the above structural design, when the first electrode lead 41 and the second electrode lead 42 are connected to an external power source (such as the battery assembly of a heating non-combustible device), the current can flow fully through the entire first heating body 11 along the circumference, thereby enabling the first heating body 11 to obtain a good power-on heating effect.

[0078] In the above embodiments including the first electrode lead 41 and the second electrode lead 42, it should be noted that, in specific implementations, the material of the first electrode lead 41 can be a metallic material such as gold, silver, copper, aluminum, nickel, gold alloy, silver alloy, aluminum alloy, copper alloy, or nickel alloy, or a conductive ceramic material. Similarly, the material of the second electrode lead 42 can be a metallic material such as gold, silver, copper, aluminum, nickel, gold alloy, silver alloy, aluminum alloy, copper alloy, or nickel alloy, or a conductive ceramic material, as long as it meets the usage requirements. This embodiment does not specifically limit the specific materials of the first electrode lead 41 and the second electrode lead 42. Furthermore, in specific implementations, the first electrode lead 41 and the second electrode lead 42 can directly make electrical contact with the first heating element 11 through sintering, embedding, or other methods; they can also be indirectly electrically connected to the first heating element 11 through welding, setting additional conductive connectors, or other methods. For example, a metal layer can be electroplated on the corresponding position of the first heating element 11, and then the electrode lead can be welded to the metal layer. Another example is... Figure 5As shown, in some embodiments, a first electrode ring 51 made of metal can be provided around the inner wall surface of the first end 111, and a second electrode ring 52 made of metal can be provided around the outer wall surface of the second end 112. Then, one end of the first electrode lead 41 is welded to the first electrode ring 51, and one end of the second electrode lead 42 is welded to the second electrode ring 52, thereby realizing the electrical connection between the first electrode lead 41 and the inner wall surface of the first end 111, and the electrical connection between the second electrode lead 42 and the outer wall surface of the second end 112. The specific electrical connection method between the first heating element 11 and the two electrode leads can be flexibly set according to actual needs, and this embodiment does not impose specific limitations on it.

[0079] Further, please refer to Figure 6-7 In some optional embodiments of this utility model, in order to facilitate easier insertion of the entire first heating element 11 into the interior of the herbal product during specific applications, the first end 111 of the first heating element 11 can be set in a pointed shape. Of course, in other optional embodiments, such as... Figure 1-5 As shown, the first end 111 of the first heating element 11 may not be sharpened. In this case, the length of the first heating element 11 along its own circumference is equal, that is, the entire end face of the first end 111 of the first heating element 11 and the entire end face of the second end 112 of the first heating element 11 are perpendicular to each other with the axis of the first heating element 11.

[0080] Further, please refer to Figure 6-9 In some optional embodiments of this utility model, in order to better avoid the problem of short circuit during the heating process of the first heating element 11, the heating assembly further includes an insulating part 12 made of insulating material, which is connected to the first heating element 11. In specific implementations, the material of the insulating part 12 can be insulating ceramic, high-temperature resistant plastic, etc., and this embodiment does not impose specific limitations on it.

[0081] Further, please refer to Figure 6-7 In some optional embodiments of this utility model, when the length of the first heating element 11 along its own circumference is equal (at this time, both the first end 111 and the second end 112 of the first heating element 11 are non-pointed structures), in order to facilitate easier insertion of the entire first heating element 11 into the interior of the herbal product during specific applications, the insulating part 12 can be made pointed, and the pointed insulating part 12 is connected to the end face of the first end 111 of the first heating element 11. Specifically, in specific implementations, the insulating part 12 can be a pointed structure such as a cone or pyramid, as long as it meets the usage requirements; this embodiment does not impose specific limitations on this.

[0082] Further, please continue to refer to Figure 1 as well as Figure 6-9 In some optional embodiments of this utility model, regardless of whether the first end 111 of the first heating element 11 is a pointed structure, in order to enable the insulating part 12 to support the inner circumferential surface of the first heating element 11, thereby enhancing the overall structural strength of the first heating element 11 and reducing the risk of breakage during use or storage and transportation, the insulating part 12 can be filled into the through hole 1101 of the first heating element 11, and the shapes of the two ends of the insulating part 12 along the axial direction of the first heating element 11 correspond to the shapes of the first end 111 and the second end 112 of the first heating element 11, respectively. For example, as Figure 6-7 As shown, when the first end 111 of the first heating element 11 is a pointed structure and the second end 112 of the first heating element 11 is a non-pointed structure, the upper end of the insulating part 12 can be set as a pointed structure that matches the shape of the first end 111, while the lower end of the insulating part 12 can be set as a non-pointed structure (such as a cylindrical shape) that matches the shape of the second end 112; for example, refer to Figure 1 and Figure 9 When the first heating element 11 is a cylindrical structure with a slit 1102 (at this time, both the first end 111 and the second end 112 of the first heating element 11 are non-pointed structures), the shape of the insulating part 12 can be set to a cylindrical shape without a point (that is, equivalent to making...). Figure 9 The pointed upper portion of the insulating part 12 shown is removed, leaving only the rod-shaped portion inside the first heating element 11 within the insulating part 12.

[0083] It should be noted here that, assuming the length of the first heating element 11 is equal along its circumference, in specific implementation, such as... Figure 1 as well as Figure 8-9 As shown, the upper pointed portion of the insulating part 12 and the rod-shaped portion located in the through hole 1101 of the insulating part 12 can exist simultaneously or separately, depending on the actual usage requirements. This embodiment does not impose specific restrictions on this.

[0084] Further, please refer to Figure 9 In some optional embodiments of this utility model, when the first through hole 1101 of the first heating element 11 is filled with the insulating part 12, a heat-insulating part made of heat-insulating material (such as aerogel, ceramic fiber, etc.) can also be sandwiched between the outer peripheral wall of the insulating part 12 and the inner peripheral wall of the first heating element 11. This arrangement can reduce the transfer of heat generated by the first heating element 11 after it is powered on to the insulating part 12 while maintaining the overall structural strength of the first heating element 11. This allows as much heat generated by the first heating element 11 as possible to be transferred outwards to the herbal product, thereby improving the heat utilization rate and ensuring the heating efficiency of the first heating element 1.

[0085] Further, please refer to Figure 8-9 In some optional embodiments of this utility model, the first heating element 1 may further include a protective part 14 made of an insulating and thermally conductive material (such as insulating ceramic, valve metal with an insulating oxide layer on the surface, etc.). The protective part 14 is a tubular structure with a wall thickness of 0.4 mm to 1.2 mm, and the inner peripheral wall of the protective part 14 is in close contact with the outer peripheral wall of the first heating element 11. This design offers several advantages. First, the protective part 14 provides support to the outer surface of the first heating element 11, enhancing its overall structural strength and reducing the risk of breakage during use or storage. Second, it protects the outer surface of the first heating element 11 from external contaminants (such as aerosols generated during heating of herbal products or residual substances after heating), improving its heating stability during use. Third, in some applications, the protective part 14 can cover the electrode leads, enhancing the aesthetic appeal of the entire heating assembly. Fourth, because the protective part 14 is made of insulating and thermally conductive material with a wall thickness of 0.4mm to 1.2mm, it achieves the aforementioned three technical effects while ensuring that the heat generated by the first heating element 11 is transferred to the herbal product as quickly as possible, thus guaranteeing the heating efficiency of the first heating element 11. It should be noted that the insulating part 12 and the protective part 13 can exist simultaneously or separately, depending on the actual usage requirements. This embodiment does not impose any specific restrictions on this.

[0086] Further, please refer to Figure 6-9 In some optional embodiments of this utility model, the heating assembly may further include a base 3 made of insulating material (such as insulating ceramic, polyetheretherketone, etc.), and the lower end of the first heating element 1 is fixed to the base 3. In some specific implementations, the lower end (i.e., the second end 112) of the first heating element 11 can be fixed to the base 3 by embedding, sintering, or other methods, thereby achieving a fixed connection between the first heating element 1 and the base 3. In other embodiments, when the through hole 1101 of the first heating element 1 is filled with insulating material... When the lower end face of the insulating part 12 protrudes through the lower port of the through hole 1101, the lower end of the insulating part 12 can also be fixed in the base 3 by means of embedding, sintering or other methods, thereby realizing the fixed connection between the first heating body 1 and the base 3. That is, the end of the insulating part 12 away from the first end 111 of the first heating body 11 protrudes through the through hole 1101 and is fixed in the base 3. At this time, the end face of the second end 112 of the first heating body 11 can be in contact with the upper end face of the base 3 or can be spaced apart from the upper end face of the base 3.

[0087] In this embodiment, in some usage scenarios where the heating component of this embodiment is applied to a non-combustible heating device, the base 3 facilitates the fixing of the entire heating component with other components of the non-combustible heating device.

[0088] In this embodiment, it should be noted that when the through hole 1101 of the first heating element 1 is filled with the insulating part 12, compared with fixing the lower end of the first heating element 11 directly to the base 3, by passing the lower end of the insulating part 12 through the through hole 1101 and fixing it to the base 3, the utilization rate of the first heating element 11 can be improved under the premise that the volume of the first heating element 11 is the same. That is, all parts of the first heating element 11 can be used to heat herbal products.

[0089] Further, please refer to Figure 7 or Figure 9 In some optional embodiments of this utility model, the heating assembly further includes a first electrode terminal 61 and a second electrode terminal 62 spaced apart. Both the first electrode terminal 61 and the second electrode terminal 62 are disposed at the bottom of the base 3. The lower end faces of both the first electrode terminal 61 and the second electrode terminal 62 are exposed from the bottom surface of the base 3. The first electrode lead 41 is electrically connected to the first heating element 11 and the first electrode terminal 61, respectively, and the second electrode lead 42 is electrically connected to the first heating element 11 and the second electrode terminal 62, respectively. With this configuration, in some scenarios where the heating assembly of this embodiment is applied to a non-combustible heating device, the positive and negative electrodes of the heating assembly can make electrical contact with the positive and negative electrodes of the battery assembly 8 in the non-combustible heating device through a pressing method. Specifically, the first electrode terminal 61 of the heating assembly can directly make electrical contact with the positive electrode of the battery assembly 8, and the second electrode terminal 62 of the heating assembly can directly make electrical contact with the negative electrode of the battery assembly 8 (e.g., ...). Figure 11-12 (as shown), without the need to electrically connect the two electrode leads to the positive and negative terminals of the battery assembly 8 by welding, thereby improving the convenience of electrical connection between the heating component and the battery assembly 8.

[0090] In this embodiment, it should be noted that, in specific implementation, the materials of the first electrode terminal 61 and the second electrode terminal 62 can be metal or conductive ceramic, as long as they meet the usage requirements. This embodiment does not impose specific limitations in this regard. Furthermore, the electrical connection method between the first electrode lead 41 and the first electrode terminal 61, and the electrical connection method between the second electrode lead 42 and the second electrode terminal 62, can be welding, pressing, or integral connection (for example, when the materials of both electrode leads and the two electrode terminals are conductive ceramic, the corresponding electrode leads and the corresponding electrode terminals can be integrally formed by sintering; or, for example, when the materials of both electrode leads and the two electrode terminals are metal, the corresponding electrode leads and the corresponding electrode terminals can be integrally formed by die casting). Any method that meets the usage requirements is acceptable, and this embodiment does not impose specific limitations in this regard.

[0091] In this embodiment, it is also necessary to explain the electrical connection method between the first electrode lead 41 and the first heating element 11 and the electrical connection method between the second electrode lead 42 and the first heating element 11. For details, please refer to the description of the previous related embodiments, which will not be repeated here.

[0092] Further, please refer to Figure 6-9 In some optional embodiments of this utility model, when the heating assembly includes a base 3, multiple heat-insulating gaps 30 can be arranged inside the base 3. These heat-insulating gaps 30 are at least used to block the heat generated by the first heating element 11 from being transferred to the bottom of the base 3, thereby reducing the heat transferred from the first heating element 11 to the base 3. This helps to reduce heat loss from the first heating element 11 during operation, thus improving the heating efficiency of the first heating element 11. Furthermore, when the heating assembly of this embodiment is applied to a heat-not-burning device, it helps to prevent the base 3 from overheating and burning other heat-sensitive components in the heat-not-burning device. Especially when electrode terminals are also provided at the bottom of the base 3, it also prevents the electrode terminals from overheating and affecting the electrical stability between the positive and negative electrodes of the battery assembly. In this embodiment, it should be noted that the distribution of the heat-insulating gaps 30 within the base 3 can be orderly (e.g., Figure 7 As shown), it can also be unordered (e.g. Figure 9 As shown in the figure, as long as the usage requirements are met, this embodiment does not impose specific limitations. Furthermore, in some optional embodiments, when the material of the base 3 is insulating ceramic, multiple heat-insulating gaps 30 can be formed within the base 3 in the following manner:

[0093] First, multiple wax balls (or wax strips) are pre-placed at predetermined positions in a specially designed mold. Then, insulating ceramic slurry is injected into the mold to form a base blank with pre-embedded wax balls. Next, the base blank is placed in a sintering furnace for sintering, so that the insulating ceramic slurry is completely sintered and solidified and the wax balls are completely melted by heat, thus obtaining a base 3 with multiple heat-insulating gaps 30 distributed inside.

[0094] Further, please refer to Figure 10 In some optional embodiments of this utility model, the heating component may further include a second heating element 2. The structure of the second heating element 2 may be any one of a metal resistance heating tube, an infrared heating tube, an electromagnetic induction heating tube, or a cylindrical conductive ceramic heating tube. The lower end of the first heating element 1 and the lower end of the second heating element 2 are both fixedly connected to the base 3. The first heating element 1 is located inside the second heating element 2, and the outer peripheral wall of the first heating element 1 and the inner peripheral wall of the second heating element 2 are spaced apart from each other.

[0095] In this embodiment, based on the above structural design, by adding a second heating element 2 for peripheral heating, the heating component of this embodiment can heat the center of the herbal product through the first heating element 1, heat the periphery of the herbal product through the second heating element 2, and heat the inside and outside of the herbal product by controlling the first heating element 1 and the second heating element 2 to work simultaneously. This improves the flexibility of the heating method of the heating component to meet different heating needs.

[0096] In this embodiment, it should be noted that references can be used. Figure 10-12In some application scenarios where the heating component of this embodiment is used in a non-combustible heating device, in order to facilitate the electrical connection between the heating component of this embodiment and the battery component 8 in the non-combustible heating device, and to facilitate the battery component 8 to control the different heating elements in the heating component, three mutually spaced electrode terminals can be provided at the bottom of the base 3. These three electrode terminals are the first electrode terminal 61, the second electrode terminal 62, and the third electrode terminal 63. At the same time, three electrodes are configured for the battery component 8, which are the first positive electrode, the negative electrode, and the second positive electrode. The positive electrode of the first heating element 1 is electrically connected to the first electrode terminal 61, the positive electrode of the second heating element 2 is electrically connected to the third electrode terminal 63, and the negative electrodes of the first heating element 1 and the second heating element 2 are both electrically connected to the second electrode terminal. The first electrode terminal 61 is electrically connected to the first positive electrode of the battery assembly, the second electrode terminal 62 is electrically connected to the negative electrode of the battery assembly, and the third electrode terminal 63 is electrically connected to the second positive electrode of the battery assembly. Thus, when the first positive and negative electrodes of the battery assembly are energized, the first heating element 1 is energized and can be used to heat the herbal product through central heating. When the second positive and negative electrodes of the battery assembly are energized, the second heating element 2 is energized and can be used to heat the herbal product through peripheral heating. When the first positive, second positive, and negative electrodes of the battery assembly are all energized, the first heating element 1 and the second heating element 2 are energized and can be used to heat the herbal product through internal and external heating.

[0097] In this embodiment, it should also be noted that the metal resistance heating tube, infrared heating tube, and electromagnetic induction heating tube mentioned above are all mature peripheral heating structures in the art, and their specific structural composition is well known to those skilled in the art, so they will not be described in detail here. As for the cylindrical conductive ceramic heating tube mentioned above, its specific structure is similar to that of the first heating body 11 described in the previous embodiment. The main difference is that the inner diameter of the cylindrical conductive ceramic heating tube is larger than the outer diameter of the first heating body 11 (the cylindrical conductive ceramic heating tube may or may not have a slit 102), which will be understood by those skilled in the art, so it will not be described in detail here.

[0098] Correspondingly, please refer to Figure 11-12 This utility model embodiment also provides a heating non-combustible device, which includes a mounting housing 7, a battery assembly 8, and a heating component (such as...) from any of the above embodiments. Figure 1-10As shown, the heating component and the battery component 8 are both installed inside the mounting housing 7. The upper end of the mounting housing 7 is provided with a receiving cavity 70 that can accommodate the herbal product 9. The first heating element 1 is located in the receiving cavity 70, and the battery component 8 is electrically connected to the first heating element 1.

[0099] In this embodiment, the battery assembly 8 may specifically include a positive electrode 81, a negative electrode 82, a power supply 83, and a control circuit board 84. The positive electrode 81 can serve as the positive electrode of the battery assembly 8, and the negative electrode 82 can serve as the negative electrode of the battery assembly 8. The control circuit board 84 is electrically connected to the power supply 83, the positive electrode 81, and the negative electrode 82. The positive electrode 81 is electrically connected to the positive electrode of the first heating element 1 (for example, the first heating element 1 can be electrically connected to the positive electrode 81 of the battery assembly 8 in sequence through the first electrode lead 41 and the first electrode terminal 61). The negative electrode 82 is electrically connected to the negative electrode of the first heating element 1 (for example, the first heating element 1 can be electrically connected to the negative electrode of the first heating element 1 in sequence through the first electrode lead 41 and the first electrode terminal 61). (The positive electrode 81 can be electrically connected to the negative electrode 82 of the battery assembly 8 via the second electrode lead 42 and the second electrode terminal 62 mentioned above). The positive electrode 81 can be an elastic electrode or a fixed electrode. Similarly, the negative electrode 82 can be an elastic electrode or a fixed electrode. The specific structure of the positive electrode 81 and the negative electrode 82 can be determined according to the actual use requirements. This embodiment does not impose specific restrictions on this. It should be noted that a fixed electrode is a type of electrode that cannot elastically expand or contract, while an elastic electrode is a type of electrode that can elastically expand or contract along its own axis. Their specific structures are well known to those skilled in the art and will not be described in detail here. The power supply 83 can be a power source such as a lithium battery. The control circuit board 84 is used to control the operation of the first heating element 1 (when the heating assembly also includes the second heating element 2, the control circuit board 84 can also be used to control the operation of the second heating element 2). When the herbal product 9 is placed in the receiving cavity 70, the power supply 83 can be controlled by the control circuit board 84 to supply power to the first heating element 1, so that the first heating element 1 is powered on and heats up, and heats and atomizes the herbal product 9 located in the receiving cavity 70, thereby generating an aerosol for the user to inhale.

[0100] In this embodiment, it should be noted that the herbal product 9 can be a low-temperature non-combustible cigarette or an herbal substance (such as tea leaves), depending on the user's actual needs. This embodiment does not impose specific limitations on this. It should be noted that a low-temperature non-combustible cigarette mainly refers to an aerosol-generating product made from materials such as tobacco shreds, tobacco particles, plant fragments, tobacco flavorings, and propylene glycol. Under low-temperature heating conditions, the nicotine and other flavoring substances inside the herbal product 9 can volatilize without producing solid particles, only generating atomized vapor. Low-temperature non-combustibility is actually a low-temperature dry distillation process, with a heating temperature generally between 200℃ and 400℃. Here, "low-temperature" refers to a heating temperature within the range of 200℃ to 400℃. Furthermore, it should be noted that in specific application scenarios, the shape of the herbal product 9 can be fixed (e.g., a columnar cigarette) or not fixed (e.g., loose tobacco shreds). This embodiment does not impose specific limitations on this.

[0101] In this embodiment, thanks to the improvements to the heating component, the heating non-combustible device of this embodiment has the same technical effect as the heating component, which will not be described again here.

[0102] It should be noted that other contents of the heating component and heating non-combustible device disclosed in this utility model can be found in the prior art, and will not be repeated here.

[0103] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
