Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a heating module and an electronic cigarette device. Background Technology

[0002] In the field of electronic cigarette technology, microwave heating technology has gained widespread and common application due to its convenience, economy, and efficiency. However, current microwave heating modules are generally equipped with waveguide structures, which inevitably leads to a relatively large size of the entire module, greatly limiting the development of electronic cigarette devices towards miniaturization.

[0003] To effectively address the technical challenge of excessively large module size, waveguide-less microwave tobacco heating devices have been proposed in related technical fields. These devices utilize electromagnetic radiation components such as transmission antennas to directly guide microwaves generated by a microwave source into a resonant cavity, thereby heating the smoking product. However, existing technologies still have significant drawbacks. Since the transmission antenna is directly placed inside the resonant cavity, it comes into direct contact with the smoking product during actual use, making it highly susceptible to contamination. A contaminated transmission antenna will experience a significant performance degradation and may also lead to a substantial decrease in heating efficiency. Furthermore, the transmission antenna, located within the resonant cavity, is prone to breakage due to external forces. Damage to the transmission antenna will directly prevent the heating device from functioning properly, ultimately adversely affecting the normal operation of the electronic cigarette's heating function.

[0004] Therefore, a heating module is needed to solve the above problems. Utility Model Content

[0005] This application provides a heating module and an electronic cigarette device that can reduce the risk of electromagnetic radiation components being contaminated or broken.

[0006] This application provides a heating module, including:

[0007] An insulating component having a receiving cavity for accommodating a smoke-generating material;

[0008] An electromagnetic wave radiation component, wherein the electromagnetic wave radiation component is disposed on the outer surface of the insulating member to form an electromagnetic resonant cavity;

[0009] The receiving cavity is at least partially located within the electromagnetic resonant cavity.

[0010] In some embodiments, the heating module further includes a heat insulation component, which is sleeved on the outer periphery of the electromagnetic wave radiation component.

[0011] In some embodiments, the insulating element and the heat insulation element are made of the same material, and the thickness of the insulating element is less than the thickness of the heat insulation element.

[0012] In some embodiments, the electromagnetic wave radiation assembly includes a first antenna radiator, a second antenna radiator, and a bridging component. The first antenna radiator and the second antenna radiator are both arranged around the outer surface of the insulating component, and the first antenna radiator and the second antenna radiator are spaced apart. The bridging component is electrically connected to the first antenna radiator and the second antenna radiator, respectively.

[0013] In some embodiments, the first antenna radiator and the second antenna radiator are spaced apart along the axial direction of the insulating member; or, the first antenna radiator and the second antenna radiator are spaced apart along the circumferential direction of the insulating member.

[0014] In some embodiments, the first antenna radiator includes a first antenna radiating segment, which extends in a circumferential or reciprocating arrangement.

[0015] In some embodiments, the shape of the cross-section of the electromagnetic resonant cavity along the axial direction is any one of elliptical, cylindrical, or frustum-shaped.

[0016] In some embodiments, the axial length of the insulating member is greater than the axial length of the electromagnetic wave radiation component, and the projection of the electromagnetic wave radiation component along a direction perpendicular to the axial length of the insulating member is located on the insulating member.

[0017] This application also provides an electronic cigarette device, including:

[0018] A heating module, wherein the heating module is the heating module described above;

[0019] An electromagnetic shielding housing is fitted over the outside of the heating module;

The electromagnetic wave radiation component surrounds the outer surface of the insulating component to form an electromagnetic resonant cavity. The receiving cavity is at least partially located within the electromagnetic resonant cavity. This heating module can reduce the risk of contamination and breakage of the electromagnetic wave radiation component. In existing heating module designs, the electromagnetic wave radiation component is often in direct contact with or close to the smoke-generating material, which easily leads to contamination of the electromagnetic wave radiation component by impurities, moisture, etc., in the smoke-generating material, thereby affecting its performance and service life. In the heating module of this application embodiment, the insulating component isolates the electromagnetic wave radiation component from the smoke-generating material, effectively avoiding direct contact and greatly reducing the possibility of contamination of the electromagnetic wave radiation component.

This structure provides better protection for the electromagnetic wave radiation component and reduces the risk of it being broken by external forces. Attached Figure Description

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] This application provides a heating module and an electronic cigarette device that can reduce the risk of electromagnetic radiation components being contaminated or broken. The following is a detailed description with reference to the accompanying drawings.

[0044] Please see Figure 1 as well as Figure 2 , Figure 1 This is a schematic diagram of a first structure of the heating module provided in an embodiment of this application. Figure 2 This is a schematic diagram of a second structure of the heating module provided in an embodiment of this application.

[0045] This application provides a heating module 10, which is a device module for heating a specific substance (such as a smoke-generating material). The heating module 10 can be applied in an electronic cigarette device 100, whereby the heating module 10 heats the smoke-generating material to produce an aerosol that can be inhaled by the user.

[0046] The heating module 10 includes an insulating component 11 and an electromagnetic wave radiation component 12. The insulating component 11 is a component with good insulation properties. In the heating module 10 of this embodiment, the insulating component 11 mainly serves to support and contain the smoke-generating material, while preventing unnecessary electrical connections or interference between the electromagnetic wave radiation component 12 and the smoke-generating material. The insulating component 11 can be formed by winding a film-layer structure, which has the characteristics of insulation, high temperature resistance, and low dielectric constant. This insulating layer can be made of PI (Polyimide) film. The PI film has a low dielectric constant (approximately 4), resulting in low microwave loss when passing through it, thus making the heating module 10 highly efficient.

[0047] The electromagnetic radiation component 12 is a combination of components capable of generating microwave radiation. In this heating module 10, the electromagnetic radiation component 12 is responsible for generating microwaves with a frequency band between 1 GHz and 30 GHz, including but not limited to 2.45 GHz and 915 MHz. Heating is achieved through the interaction between the microwaves and the smoke-generating material. High-frequency electromagnetic waves cause water molecules within the smoke-generating material to vibrate violently in the microwave high-frequency electromagnetic field, converting molecular friction into heat energy, thus heating the smoke-generating material. The advantage of this technology is that any object containing water molecules can be heated, reducing the heat absorption and heat transfer losses of traditional heating elements (conductive heating), resulting in advantages such as fast heating speed, high efficiency, and low heat loss.

[0048] Please see Figure 3 , Figure 3 A schematic diagram of the first unfolded structure of the electromagnetic wave radiation component provided in the embodiments of this application: Figures (1) to (3) show three different structures of the electromagnetic wave radiation component. The electromagnetic wave radiation component 12 can be formed by winding a sheet-like structure or a plate-like structure, such as... Figure 3As shown in (1) to (3), the thickness of the sheet-like or plate-like structure can be from 0.01 mm to 0.1 mm. In some cases, the insulating element 11 and the electromagnetic wave radiation component 12 can be stacked and wound to form a heating module 10.

[0049] The insulating component 11 has a receiving cavity with a smooth inner surface for easy cleaning. The receiving cavity is used to contain the smoking material and provides a relatively stable heating environment for it. The smoking material is a substance that can produce aerosols when heated, typically containing tobacco or other plant components. After heating, it releases aerosols containing flavoring components and nicotine for user use.

[0050] Figure 4 A schematic diagram of the third structure of the heating module provided in this application embodiment: Figures (1) to (3) show three different structures of the heating module. The electromagnetic wave radiation component 12 surrounds the outer surface of the insulating member 11 to form an electromagnetic resonant cavity 121, so that microwaves can uniformly heat the smoking material without gaps at 360°. When the microwaves generated by the electromagnetic wave radiation component 12 propagate in the electromagnetic resonant cavity 121, a resonance phenomenon occurs, which enhances the energy density of the microwaves, thereby improving the heating efficiency of the smoking material.

[0051] The receiving cavity is at least partially located within the electromagnetic resonant cavity 121, allowing the smoke-generating material to be fully exposed to microwave radiation, thereby improving heating efficiency. Simultaneously, since microwaves can pass through the insulating component 11 and act on the smoke-generating material, energy loss during transmission is reduced, further enhancing the heating effect.

[0052] The heating module 10 provided in this application embodiment can reduce the risk of contamination and breakage of the electromagnetic wave radiation component 12. In existing heating module 10 designs, the electromagnetic wave radiation component 12 is often in direct contact with or close to the smoke-generating material, which easily leads to contamination of the electromagnetic wave radiation component 12 by impurities, moisture, etc. in the smoke-generating material, thereby affecting its performance and service life. In the heating module 10 of this application embodiment, the insulating component 11 isolates the electromagnetic wave radiation component 12 from the smoke-generating material, effectively avoiding direct contact and greatly reducing the possibility of contamination of the electromagnetic wave radiation component 12. In addition, in some traditional heating modules 10, the structure of the electromagnetic wave radiation component 12 is relatively fragile and easily broken by external forces. For example, during the assembly, transportation, or use of the equipment, the electromagnetic wave radiation component 12 may be damaged due to collisions, squeezing, etc. In the heating module 10 of this application embodiment, the electromagnetic wave radiation component 12 is surrounded by the outer surface of the insulating component 11 to form an electromagnetic resonant cavity 121. This structure provides better protection for the electromagnetic wave radiation component 12 and reduces the risk of breakage due to external forces.

[0053] Please see Figure 5 , Figure 5 This is a first circuit diagram of a heating module provided in an embodiment of this application. The heating module 10 also includes a power supply 15, a voltage regulation circuit 16, and an radio frequency chip 17. These components work together to achieve the conversion and precise control of electrical energy into heat energy. The power supply 15 uses a lithium battery to power the voltage regulation circuit 16 and the radio frequency chip 17. The voltage regulation circuit 16 can flexibly adjust its output voltage based on the signal from the radio frequency chip 17 to change the heating power. The radio frequency chip 17 can convert direct current into microwaves and can also intelligently control the heating based on temperature feedback.

[0054] In some embodiments, please refer to Figure 6 as well as Figure 7 , Figure 6 This is a schematic diagram of a fourth structure of the heating module provided in the embodiments of this application. Figure 7 This is a fifth structural schematic diagram of the heating module provided in this application embodiment. The heating module 10 also includes a heat insulation component 13, which is sleeved on the outer periphery of the electromagnetic wave radiation component 12. The heat insulation component 13 is a component with good heat insulation performance, and its main function is to prevent heat from being transferred from the electromagnetic wave radiation component 12 to the surrounding environment, reduce heat loss, and protect surrounding components from high temperatures, ensuring the safety and stability of the heating module 10. The material of the heat insulation component 13 can also be an insulating material, which can protect and fix the electromagnetic wave radiation component 12.

[0055] When the electromagnetic wave radiation component 12 is working, it generates a large amount of heat. Without the protection of the heat insulation component 13, this heat would be rapidly transferred to the surrounding environment, leading to heat loss, reduced heating efficiency, and potentially damage to surrounding components due to overheating, thus affecting the normal operation of the heating module 10. The heat insulation component 13, fitted around the outer periphery of the electromagnetic wave radiation component 12, effectively prevents heat transfer, concentrating heat in the area requiring heating and improving heating efficiency.

[0056] In this design, the insulating component 11 and the heat insulation component 13 are made of the same material; for example, both the insulating substrate and the heat insulation layer are made of PI (polyethylene terephthalate). PI film is characterized by its insulating properties and high-temperature resistance. During processing, because the insulating component 11 and the heat insulation component 13 are made of the same material, the processing technology and equipment can be interchanged, improving production efficiency.

[0057] The thickness of the insulating component 11 is less than the thickness of the heat insulation component 13. The insulating component 11 mainly serves as insulation and support; its relatively thin thickness meets the requirements for insulation performance and does not occupy too much space, which is beneficial for the miniaturization design of the heating module 10. The heat insulation component 13, on the other hand, needs to withstand higher temperatures and greater heat transfer pressure; its thicker thickness provides better heat insulation, ensuring that the heat generated by the electromagnetic radiation component 12 is not transferred to the surrounding environment. For example, in this embodiment, the thickness of the insulating component 11 is less than or equal to 1 mm, such as 0.05 mm, 0.1 mm, 0.5 mm, 0.8 mm, etc. The thickness of the heat insulation component 13 is greater than 1 mm, such as 1.5 mm, 2 mm, 3 mm, 5 mm, etc. In light of the above, when both the insulating substrate and the heat insulation layer are made of PI film, the thickness of a single PI film is 0.01 mm to 0.1 mm. The insulating component 11 can be composed of a single layer, double layer, 5 layers, 7 layers, or 8 layers of PI film stacked together, while the heat insulation component 13 can be composed of dozens of layers of PI film stacked together, ranging from 10 to 50 layers. The heat insulation component 13 can effectively prevent heat transfer, keeping the temperature around the electromagnetic wave radiation component 12 within a safe range, while the insulating component 11 can also perform its insulating function normally.

[0058] In the electronic cigarette device 100, the use of this heating module 10 can improve heating efficiency, allowing the smoke-generating material to reach the appropriate temperature more quickly, producing a richer and more stable aerosol. At the same time, the protective function of the heat insulation component 13 can extend the service life of the electromagnetic wave radiation component 12 and reduce damage and malfunctions caused by overheating.

[0059] Furthermore, since the insulating component 11 and the heat insulation component 13 are made of the same material, the overall structure of the heating module 10 is simpler, making it easier to assemble and maintain. During the production process, this design also facilitates quality control, improving the reliability and stability of the product.

[0060] Compared with existing heating modules 10, the heating module 10 of this application embodiment has more obvious advantages. In existing heating modules 10, the insulating component 11 and the heat insulation component 13 may be made of different materials, which not only increases the complexity and cost of material procurement, but also makes it difficult to use the same processing technology and equipment, resulting in low production efficiency. Moreover, the physical properties such as the coefficient of thermal expansion of different materials may differ. During long-term use, problems such as loosening and damage of components due to inconsistent thermal expansion and contraction are prone to occur, affecting the stability and service life of the heating module 10.

[0061] In some embodiments, please refer to Figure 8 as well as Figure 9 , Figure 8 A schematic diagram of the second unfolded structure of the electromagnetic wave radiation component provided in the embodiments of this application: Figures (1) to (2) show two different structures of the electromagnetic wave radiation component; Figure 9 A schematic diagram of the third unfolded structure of the electromagnetic wave radiation component provided in this application embodiment: Figures (1) to (5) show five different structures of the electromagnetic wave radiation component. The electromagnetic wave radiation component 12 includes a first antenna radiator 122, a second antenna radiator 123, and a bridging component 124. The first antenna radiator 122, as part of the electromagnetic wave radiation component 12, is an important structure for transmitting microwaves and can effectively radiate the microwave signal generated by the microwave source. Its shape and arrangement affect the radiation range and intensity of the microwave. The second antenna radiator 123 is similar to the first antenna radiator 122 and is also a structure in the electromagnetic wave radiation component 12 used for transmitting microwaves. It cooperates with the first antenna radiator 122 to jointly complete the task of radiating microwaves. The bridging component 124 is a component used to connect the first antenna radiator 122 and the second antenna radiator 123. Its main function is to realize the electrical connection between the two antenna radiators, ensure that the microwave signal can be transmitted smoothly between them, and ensure the normal operation of the electromagnetic wave radiation component 12.

[0062] Both the first antenna radiator 122 and the second antenna radiator 123 are arranged around the outer surface of the insulating member 11. This arrangement makes full use of the space on the outer surface of the insulating member 11, resulting in more uniform microwave radiation. The first antenna radiator 122 and the second antenna radiator 123 are spaced apart to avoid mutual interference between them, ensuring the independence and stability of the microwave signal.

[0063] Please continue reading. Figure 8 as well as Figure 9 The bridging component 124 is electrically connected to the first antenna radiator 122 and the second antenna radiator 123, respectively. The bridging component 124 is made of a metal material with good electrical conductivity to ensure a strong connection with the first antenna radiator 122 and the second antenna radiator 123 with minimal resistance. Through this reliable electrical connection, the microwave signal generated by the microwave source can be efficiently transmitted to the first antenna radiator 122 and the second antenna radiator 123, thereby achieving effective microwave radiation.

[0064] The first antenna radiator 122, the second antenna radiator 123, and the bridging component 124 can be integrally molded. Integral molding is a manufacturing process that involves simultaneously manufacturing the first antenna radiator 122, the second antenna radiator 123, and the bridging component 124 in a single molding process using specific molds and techniques. This process avoids problems such as part mismatch errors and weak connections that may occur in traditional assembly methods, improving the overall performance and reliability of the component. The integral molding design enables the electromagnetic wave radiating component 12 to radiate microwaves more uniformly and efficiently. Due to the tight connection and stable electrical performance between the antenna radiator and the bridging component 124, microwave signals can be transmitted smoothly between them, reducing signal attenuation and interference.

[0065] In some cases, the first antenna radiator 122 and the second antenna radiator 123 are spaced apart along the axial direction of the insulating member 11. The axial direction refers to the direction of the central axis of the insulating member 11, i.e., the direction extending along the length of the insulating member 11. The first antenna radiator 122 and the second antenna radiator 123 maintain a certain distance along the length of the insulating member 11. This arrangement allows microwaves to form different radiation regions in the axial direction, meeting the heating requirements of smoke-generating materials of different shapes and sizes. For example, for some longer smoke-generating materials, the first antenna radiator 122 and the second antenna radiator 123 can ensure that the smoke-generating material receives uniform microwave radiation throughout its entire length, improving the heating effect.

[0066] In other cases, the first antenna radiator 122 and the second antenna radiator 123 are spaced apart circumferentially around the insulating member 11. Circumferential refers to the direction around the central axis of the insulating member 11, i.e., the circumferential direction of the outer surface of the insulating member 11. The first antenna radiator 122 and the second antenna radiator 123 are uniformly distributed circumferentially around the insulating member 11. This arrangement allows microwaves to form a uniform radiation field in the circumferential direction, avoiding situations where local radiation is too strong or too weak. For example, around a circular emitting material, the circumferentially spaced first antenna radiator 122 and second antenna radiator 123 can ensure that all locations on the surface of the emitting material receive microwave radiation of the same intensity, guaranteeing uniform heating.

[0067] Please continue reading for more details. Figure 8 as well as Figure 9 The first antenna radiator 122 includes a first antenna radiating segment 1221, which extends in a circumferential or reciprocating arrangement.

[0068] It is understandable that by adjusting the number, length, thickness, material, and thickness of the lines in the first antenna radiating segment 1221, the electromagnetic wave emission frequency and intensity can be adjusted. The high-frequency electromagnetic waves cause the water molecules in the smoke-generating material to move and generate friction, thereby achieving the purpose of heating.

[0069] Please continue reading. Figure 8 When the first antenna radiating segment 1221 extends in a circumferential arrangement, it acts like a coil wrapped around the outer surface of the insulating component 11, generating a relatively uniform microwave radiation field. This arrangement is suitable for applications requiring high heating uniformity. The circumferentially extending antenna radiating segment ensures that the heated object receives the same microwave radiation in all directions, thereby achieving precise temperature control.

[0070] Please continue reading. Figure 9 When the first antenna radiating segment 1221 extends in a reciprocating arrangement, it will generate strong microwave radiation in certain areas. This arrangement is suitable for applications requiring high local heating efficiency, as the reciprocating antenna radiating segments can concentrate microwave energy and improve the heating efficiency of local areas.

[0071] The second antenna radiator 123 includes a second antenna radiating segment 1231, which extends in a circular or reciprocating arrangement. Its structure and technical effect are similar to those of the first antenna radiator 122, and will not be described in detail here.

[0072] Please continue reading. Figure 8 as well as Figure 9 When the electromagnetic wave radiating component 12 is unfolded into a plane, the first antenna radiator 122 and the second antenna radiator 123 can be mirror-symmetrically arranged or centrally symmetrically arranged. Each of these two symmetrical arrangement methods has its own unique advantages, which will be explained in detail below.

[0073] Please see Figure 8 (1) Figure 9 (2) to Figure 9 (5) Mirror symmetry means that the first antenna radiator 122 and the second antenna radiator 123 are mirror images of each other about a certain plane, so that microwave radiation forms similar radiation fields on both sides of the plane. From a physical point of view, when the microwave signal is transmitted from the microwave source to the antenna radiator, due to the mirror symmetry structure, the distribution and propagation of microwaves on the two antenna radiators are consistent, thus ensuring the symmetry of the radiation field.

[0074] Please see Figure 8 (2) and Figure 9 (1) The centrally symmetrical arrangement means that the first antenna radiator 122 and the second antenna radiator 123 are centrally symmetrical about a certain point, which can achieve uniform microwave radiation in all directions. Since the two antenna radiators are symmetrically distributed around the central point, the microwave signal can spread and propagate uniformly in space, avoiding the situation of excessively strong or weak local radiation.

[0075] In some embodiments, please refer to Figure 10 , Figure 10 A sixth structural schematic diagram of the heating module provided in the embodiments of this application: Figures (1) to (2) show two different structures of the heating module. The cross-sectional shape of the electromagnetic resonant cavity 121 along the axial direction is elliptical or cylindrical, such as... Figure 10 (1) Or frustum-shaped, such as Figure 10 (2) Any one of them.

[0076] The elliptical cross-section electromagnetic resonant cavity 121 possesses a unique microwave propagation mode. Due to the elliptical geometry, microwaves reflect back and forth between the two foci as they propagate within the cavity, resulting in a more concentrated energy distribution. This concentrated energy distribution helps improve the interaction efficiency between microwaves and the smoke-generating material, making heating more focused and efficient.

[0077] The manufacturing process of the cylindrical cross-section electromagnetic resonant cavity 121 is relatively simple and cost-effective. Meanwhile, the cylindrical resonant cavity can provide a more uniform microwave field distribution. In the cylindrical resonant cavity, microwaves propagate uniformly in the circumferential direction, ensuring that the microwave radiation intensity received by the smoke-generating material is similar in all directions, thereby guaranteeing uniform heating.

[0078] The frustum-shaped electromagnetic resonant cavity 121 can adjust the microwave distribution to a certain extent. Because the upper and lower bases of the frustum are of different sizes, microwaves gradually converge towards the smaller base as they propagate within the cavity, thus creating a higher energy density in that region. This characteristic allows the frustum-shaped resonant cavity to meet the heating requirements of smoke-generating materials of different shapes and sizes.

[0079] In some embodiments, the axial length of the insulating member 11 is greater than the axial length of the electromagnetic wave radiation component 12, providing more adequate insulation protection for the electromagnetic wave radiation component 12. During the operation of the heating module 10, the electromagnetic wave radiation component 12 generates a high-frequency electric field. Insufficient insulation protection may lead to safety issues such as electrical short circuits. The longer insulating member 11 ensures sufficient insulation distance between the electromagnetic wave radiation component 12 and the surrounding environment, effectively preventing leakage and improving the safety and reliability of the heating module 10. The projection of the electromagnetic wave radiation component 12 along the axial length direction perpendicular to the insulating member 11 is located on the insulating member 11, ensuring the stability of the installation of the electromagnetic wave radiation component 12. This design allows the electromagnetic wave radiation component 12 to be firmly fixed to the insulating member 11, avoiding displacement due to vibration or external forces during operation, thereby ensuring the accuracy and stability of microwave radiation.

[0080] In some embodiments, the heating module 10 further includes a pin 14, one end of which is closely connected to the electromagnetic wave radiation component 12 to ensure stable transmission of electrical signals and energy from the electromagnetic wave radiation component 12; while the other end is exposed on the edge of the insulating component 11. This layout facilitates connection to external circuits or other devices and can, to some extent, prevent the pin 14 from being interfered with by the complex electromagnetic environment inside the insulating component 11.

[0081] Pin 14 enables the heating module 10 to achieve electrical connection and signal interaction more conveniently and efficiently when working with other components, providing a strong guarantee for stable operation and performance of collaborative work, and also bringing great convenience to the installation, debugging and maintenance of the heating module 10.

[0082] Please see Figure 11 as well as Figure 12 , Figure 11 This is a schematic diagram of a first structure of an electronic cigarette device provided in an embodiment of this application. Figure 12 for Figure 11 A schematic diagram of the exploded structure. This application also provides an electronic cigarette device 100, which is a device that mimics a traditional cigarette, using electronic heating to generate an aerosol from a smoke-generating material for the user to inhale.

[0083] The electronic cigarette device 100 includes the heating module 10, electromagnetic shielding housing 20, first fixing member 30, and second fixing member 40 as described in the above embodiments.

[0084] The heating module 10 is the core heating component in the electronic cigarette device 100, responsible for converting electrical energy into heat energy to heat the smoke-generating material. Its performance directly affects the heating efficiency, uniformity, and stability of the electronic cigarette device 100. In this electronic cigarette device 100, the heating module 10 adopts the structure mentioned above, which has a specific cross-sectional shape of the electromagnetic resonant cavity 121 and the axial length relationship between the insulating component 11 and the electromagnetic wave radiation component 12.

[0085] The electromagnetic shielding housing 20 is fitted onto the outside of the heating module 10, and its length is greater than that of the electromagnetic wave radiation component 12. The electromagnetic shielding housing 20 is a shell made of metal or other conductive material fitted onto the outside of the heating module 10, and it is grounded. The main function of the electromagnetic shielding housing 20 is to effectively shield the electromagnetic radiation generated by the heating module 10 during operation, minimizing interference to the human body and surrounding electronic equipment; on the other hand, it also provides some protection for the heating module 10, preventing it from being damaged by external physical forces.

[0086] In the design of the electronic cigarette device 100, the electromagnetic shielding shell 20 and the heating module 10 are arranged in a spaced manner. Specifically, a certain space is left between the electromagnetic shielding shell 20 and the electromagnetic wave radiation component 12 or heat insulation component 13 of the heating module 10, forming an air layer, which brings a significant heat insulation effect.

[0087] The air layer effectively prevents the heat generated by the heating module 10 during operation from being transferred to the electromagnetic shielding housing 20. Since the heating module 10 generates a high temperature during operation, if it is not effectively insulated, the heat can easily be conducted to the outer shell of the electronic cigarette device 100, causing the outer shell to become hot, affecting the user experience, and may even cause safety hazards due to burns.

[0088] Please see Figure 13 , Figure 13 This is a second circuit diagram of the heating module provided in an embodiment of this application.

[0089] In the application of the electronic cigarette device 100, the electromagnetic resonant cavity 121 converts microwaves into heat energy, atomizing the smoke-generating material. A temperature sensor 18 is installed inside the electromagnetic resonant cavity 121 to sense the temperature in real time and transmit the signal to the radio frequency chip 17. The radio frequency chip 17 uses adaptive PWM modulation technology to adjust the PWM signal pulse width according to the difference between the temperature and the set value, controlling the voltage regulation circuit 16 to change the output voltage, thereby precisely regulating the microwave pulse power output and stabilizing the heating temperature of the electronic cigarette device 100 within the set range.

[0090] When the heating module 10 is working, the power supply 15 supplies power to the radio frequency chip 17, which in turn controls the voltage regulation circuit 16 to generate a high-frequency alternating current. The current is transmitted through the electromagnetic wave radiation component 12 and generates microwaves. The microwaves pass through the insulating component 11 and heat the smoke-generating material. When the microwaves continue to propagate and encounter the electromagnetic shielding shell 20, they are reflected back and thus confined within the electromagnetic resonant cavity 121, achieving continuous heating of the smoke-generating material from all directions and ensuring heating effect and stability.

[0091] Please continue reading. Figure 11 , Figure 14 as well as Figure 15 , Figure 14 This is a schematic diagram of a third structure of the electronic cigarette device provided in an embodiment of this application. Figure 15 This is a schematic diagram of the fourth structure of the electronic cigarette device provided in the embodiments of this application.

[0092] The first fixing member 30 can be an upper structural component, also known as an end cap. The material of the first fixing member 30 can be a high-temperature resistant insulating material. The first fixing member 30 can be used to connect and fix smoking materials such as cigarette sticks, and to fix other structures of the electronic cigarette device 100. The first fixing member 30 is a component set at one end of the electromagnetic shielding shell 20, used to fix the heating module 10. The first fixing member 30 and the heating module 10 are stably connected through a specific connection method to ensure that the heating module 10 is fixed in position in the electronic cigarette device 100, and to ensure the normal operation of the electronic cigarette device 100.

[0093] The second fixing member 40 is a component located at the other end of the electromagnetic shielding housing 20, and also serves to fix the heating module 10. It cooperates with the first fixing member 30 to ensure the stability of the heating module 10 within the electromagnetic shielding housing 20. The second fixing member 40 can be a lower structural component, also known as a base. The material of the second fixing member 40 can be a high-temperature resistant insulating material. The second fixing member 40 can also be used to fix other structures of the electronic cigarette device 100.

[0094] The first fixing member 30 is disposed at one end of the electromagnetic shielding housing 20; the second fixing member 40 is disposed at the other end of the electromagnetic shielding housing 20. The heating module 10 is fixedly connected to the first fixing member 30 and / or the second fixing member 40. A stable connection is formed between the first fixing member 30, the second fixing member 40, and the heating module 10, ensuring that the heating module 10 is always in the correct position within the electronic cigarette device 100, thus guaranteeing the normal operation of the electronic cigarette device 100.

[0095] The first fixing member 30 and the second fixing member 40 are respectively disposed at both ends of the electromagnetic shielding housing 20, forming a stable connection with the heating module 10. This design of fixing at both ends provides stronger support and stability compared to fixing at one end, reducing vibration and displacement of the heating module 10 during operation, thereby improving the accuracy and stability of heating.

[0096] Please see Figure 16 , Figure 16This is a fifth structural schematic diagram of the electronic cigarette device provided in this application embodiment. When the heating module 10 is connected to the first fixing member 30, the first fixing member 30 has a limiting groove 31 on the side facing the heating module 10, and the heating module 10 is embedded in the limiting groove 31 with an interference fit. This connection method has several advantages. The limiting groove 31 can be an annular limiting groove 31. When the heating module 10 is embedded in the limiting groove 31, the heating module 10 will be in an outward expanding state on one side of the limiting groove 31, with an overall shape similar to a trumpet. This design not only makes the connection between the heating module 10 and the first fixing member 30 tighter and more stable, effectively preventing the heating module 10 from loosening or shifting due to vibration or external force during operation, ensuring the stability and reliability of the entire system; but also, this trumpet-shaped structure helps to optimize the electromagnetic field distribution around the heating module 10, further improving the working efficiency and performance of the heating module 10.

[0097] From the perspective of connection strength, the interference fit allows for greater friction between the heating module 10 and the limiting groove 31, thus ensuring a firm connection between the two. During the use of the electronic cigarette device 100, it will experience various complex operating conditions, such as shaking during carrying and vibration during inhalation. The interference fit connection effectively prevents the heating module 10 from separating from the first fixing member 30, ensuring the reliability of the electronic cigarette device 100.

[0098] In terms of positioning accuracy, the design of the limiting groove 31 can precisely limit the position of the heating module 10, enabling it to be positioned quickly and accurately during installation. This helps improve the assembly efficiency of the electronic cigarette device 100, while also ensuring the relative positional accuracy between the heating module 10 and other components, thus ensuring the performance consistency of the electronic cigarette device 100.

[0099] Furthermore, the interference fit also provides a certain degree of sealing. In the electronic cigarette device 100, there may be some tiny gaps around the heating module 10. Without sealing, this could lead to aerosol leakage or the entry of external impurities. The interference fit connection can, to some extent, fill these gaps, reducing the risk of aerosol leakage, and simultaneously preventing external dust, moisture, and other impurities from entering the electronic cigarette device 100 and affecting the performance and lifespan of the heating module 10.

[0100] In the heating module 10 and electronic cigarette device 100 provided in this application embodiment, the heating module 10 includes an insulating member 11 and an electromagnetic wave radiation component 12. The insulating member 11 has a receiving cavity for accommodating the smoke-generating material. The electromagnetic wave radiation component 12 surrounds the outer surface of the insulating member 11 to form an electromagnetic resonant cavity 121. The receiving cavity is at least partially located within the electromagnetic resonant cavity 121. This heating module 10 can reduce the risk of contamination and breakage of the electromagnetic wave radiation component 12. In existing heating module 10 designs, the electromagnetic wave radiation component 12 is often in direct contact with or close to the smoke-generating material, which easily leads to contamination of the electromagnetic wave radiation component 12 by impurities, moisture, etc., in the smoke-generating material, thereby affecting its performance and service life. However, in the heating module 10 of this application embodiment, the insulating member 11 isolates the electromagnetic wave radiation component 12 from the smoke-generating material, effectively avoiding direct contact and greatly reducing the possibility of contamination of the electromagnetic wave radiation component 12. Furthermore, in some traditional heating modules 10, the electromagnetic wave radiation component 12 has a relatively fragile structure and is easily broken by external forces. For example, during the assembly, transportation, or use of the heating module 10, the electromagnetic wave radiation component 12 may be damaged due to collisions, compression, or other reasons. However, in the heating module 10 of this application embodiment, the electromagnetic wave radiation component 12 is surrounded by the outer surface of the insulating component 11 to form an electromagnetic resonant cavity 121. This structure provides better protection for the electromagnetic wave radiation component 12 and reduces the risk of breakage due to external forces.
