Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarette devices, and in particular, to a heating module and an electronic cigarette device. Background Art

[0002] In the technical field of electronic cigarette devices, microwave heating technology has been widely and commonly applied due to its advantages of convenience, economy, and high efficiency. However, currently, microwave heating modules are generally configured with waveguide structures, which inevitably lead to a relatively large volume of the entire module, greatly restricting the development of electronic cigarette devices towards miniaturization.

[0003] To effectively solve the technical problem of the too large volume of the module, a waveguide-free microwave tobacco heating device has been proposed in the related technical field. Such a device uses electromagnetic wave radiation components such as transmission antennas to directly introduce the microwave generated by the microwave source into the resonant cavity, and then realizes the heating operation of the smoking article. However, the existing such technologies still have significant defects. Since the transmission antenna is directly arranged inside the resonant cavity, during actual use, the transmission antenna will come into direct contact with the smoking article, which makes the transmission antenna extremely vulnerable to contamination. The contaminated transmission antenna will have a significant reduction in performance, and may also cause a significant decrease in heating efficiency. In addition, the transmission antenna inside the resonant cavity is prone to break due to external forces. Once the transmission antenna is damaged, it will directly cause the heating device to malfunction, ultimately having an adverse impact on the normal realization of the electronic cigarette heating function.

[0004] Therefore, a heating module is needed to solve the above problems. Summary of the Invention

[0005] The embodiments of the present application provide a heating module and an electronic cigarette device, which can reduce the risk of the electromagnetic wave radiation component being contaminated and broken.

[0006] The embodiments of the present application provide a heating module, including:

[0007] An insulating member having a receiving cavity for receiving a smoking material;

[0008] An electromagnetic wave radiation component surrounding the outer surface of the insulating member to form an electromagnetic resonant cavity;

[0009] Wherein, at least part of the receiving cavity is located inside the electromagnetic resonant cavity.

[0010] In some embodiments, the heating module further includes a heat insulating member sleeved on the outer peripheral side of the electromagnetic wave radiation component.

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

[0012] In some embodiments, the electromagnetic wave radiation assembly includes a first antenna radiator, a second antenna radiator, and a bridging member. The first antenna radiator and the second antenna radiator are both disposed around the outer surface of the insulating member. The first antenna radiator and the second antenna radiator are spaced apart, and the bridging member 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; alternatively, 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 radiation segment, and the first antenna radiation segment extends in a circular arrangement or a 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 an ellipse, a cylinder, or a frustum of a cone.

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

[0017] The embodiment of the present application further provides an electronic cigarette device, including:

[0018] A heating module, where the heating module is the above-mentioned heating module;

[0019] An electromagnetic shielding housing, which is sleeved outside the heating module;

[0020] A first fixing member, which is disposed at one end of the electromagnetic shielding housing;

[0021] A second fixing member, which is disposed at the other end of the electromagnetic shielding housing;

[0022] Wherein, the heating module is fixedly connected to the first fixing member and / or the second fixing member.

[0023] In some embodiments, when the heating module is connected to the first fixing member, a limiting groove is provided on the side of the first fixing member facing the heating module, and the heating module is embedded in the limiting groove in an interference fit manner.

[0024] In the heating module and the electronic cigarette device provided by the embodiments of the present application, the heating module includes an insulating member and an electromagnetic wave radiation component. The insulating member has a receiving cavity for receiving a smoking material. The electromagnetic wave radiation component surrounds the outer surface of the insulating member to form an electromagnetic resonance cavity. At least a part of the receiving cavity is located within the electromagnetic resonance cavity. This heating module can reduce the risks of the electromagnetic wave radiation component being contaminated and broken. In the existing heating module designs, the electromagnetic wave radiation component often directly contacts the smoking material or is in close proximity thereto, which easily leads to the electromagnetic wave radiation component being contaminated by impurities, moisture, etc. in the smoking material, thereby affecting its performance and service life. In the heating module of the embodiments of the present application, the insulating member separates the electromagnetic wave radiation component from the smoking material, effectively avoiding direct contact and greatly reducing the possibility of the electromagnetic wave radiation component being contaminated. In addition, in some traditional heating modules, the structure of the electromagnetic wave radiation component is relatively fragile and is easily broken under the action of external forces. For example, during the assembly, transportation, or use of the heating module, the electromagnetic wave radiation component may be damaged due to reasons such as collision or extrusion. In the heating module of the embodiments of the present application, the electromagnetic wave radiation component surrounds the outer surface of the insulating member to form an electromagnetic resonance cavity, and this structure provides better protection for the electromagnetic wave radiation component and reduces the risk of being broken under the action of external forces.

[0042] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0043] Embodiments of the present application provide a heating module and an electronic cigarette device, which can reduce the risks of the electromagnetic wave radiation component being contaminated and broken. Specific descriptions are given below with reference to the accompanying drawings.

[0044] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. (1) is a first schematic structural diagram of the heating module provided by the embodiments of the present application, Figure 2 FIG. (2) is a second schematic structural diagram of the heating module provided by the embodiments of the present application.

[0045] The present application provides a heating module 10, which is a device module for heating a specific substance (such as a smoking material). The heating module 10 can be applied to an electronic cigarette device 100, and the heating module 10 heats the smoking material to generate an aerosol that can be inhaled by the user.

[0046] The heating module 10 includes an insulating member 11 and an electromagnetic wave radiation component 12. The insulating member 11 is a component with good insulation performance. In the heating module 10 of the embodiments of the present application, the insulating member 11 mainly plays a role in supporting and accommodating the smoking material, and at the same time prevents unnecessary electrical connection or interference between the electromagnetic wave radiation component 12 and the smoking material. The insulating member 11 can be wound by a film-like structure, and the film-like structure has the characteristics of insulation, high temperature resistance and low dielectric constant. The insulating layer can be made of a PI (Polyimide) film. The PI film has a low dielectric constant (about 4), and the loss of microwave passing through the PI film is small, so that the heating efficiency of the heating module 10 is high.

[0047] The electromagnetic wave radiation component 12 is a combination of components that can generate microwave radiation. In the heating module 10, the electromagnetic wave radiation component 12 is responsible for generating microwaves, and the frequency band of the microwaves is between 1 GHz and 30 GHz, and the frequency band includes but is not limited to 2.45 GHz and 915 MHz. The heating purpose is achieved through the interaction between the microwaves and the smoking material. Through the high-frequency electromagnetic waves, the water molecules in the smoking material will vibrate violently in the microwave high-frequency electromagnetic field, and the molecular friction is converted into heat energy to heat the smoking material. The advantage of this technology is that any object containing water molecules can be heated, reducing the heat loss of the traditional heating element (conduction heating) due to heat absorption and heat transfer, and having the advantages of fast heating speed, high efficiency and small heat loss.

[0048] Please refer to Figure 3 , Figure 3 FIG. (4) is a first unfolded schematic structural diagram of the electromagnetic wave radiation component provided by the embodiments of the present application: FIGS. (1) to (3) are 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) therein, the thickness of the sheet-like structure or plate-like structure can be 0.01 mm to 0.1 mm. In some cases, the insulating member 11 and the electromagnetic wave radiation component 12 can be stacked and wound to form a heating module 10.

[0049] The insulating member 11 has a receiving cavity. The inner surface of the receiving cavity is smooth and easy to clean. The receiving cavity is used to receive the fuming material, and provides a relatively stable heating environment for the fuming material. The fuming material is a substance that can generate aerosol when heated, usually containing tobacco or other plant components, and releases an aerosol containing fragrance components and nicotine and other substances after heating for users to use.

[0050] Figure 4 This is the third structural schematic diagram of the heating module provided by the embodiment of the present application: Figures (1) to (3) are 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 resonance cavity 121, so that the microwave can uniformly heat the fuming material without interval of 360°. When the microwave generated by the electromagnetic wave radiation component 12 propagates in the electromagnetic resonance cavity 121, a resonance phenomenon will occur, enhancing the energy density of the microwave, thereby improving the heating efficiency of the fuming material.

[0051] At least part of the receiving cavity is located in the electromagnetic resonance cavity 121, so that the fuming material can be fully exposed to the microwave radiation environment, thereby improving the heating efficiency. At the same time, since the microwave can pass through the insulating member 11 and act on the fuming material, the energy loss during the transmission process is reduced, further improving the heating effect.

[0052] The heating module 10 provided by the embodiment of the present application can reduce the risk of the electromagnetic wave radiation component 12 being contaminated and broken. In the design of the existing heating module 10, the electromagnetic wave radiation component 12 often directly contacts the fuming material or is relatively close, which easily causes the electromagnetic wave radiation component 12 to be contaminated by impurities, moisture, etc. in the fuming material, thus affecting its performance and service life. In the heating module 10 of the embodiment of the present application, the insulating member 11 isolates the electromagnetic wave radiation component 12 from the fuming material, effectively avoiding direct contact and greatly reducing the possibility of the electromagnetic wave radiation component 12 being contaminated. In addition, in some traditional heating modules 10, the structure of the electromagnetic wave radiation component 12 is relatively fragile and is easily broken by external forces. For example, during the assembly, transportation or use of the device, the electromagnetic wave radiation component 12 may be damaged due to collision, extrusion, etc. In the heating module 10 of the embodiment of the present application, the electromagnetic wave radiation component 12 surrounds the outer surface of the insulating member 11 to form an electromagnetic resonance cavity 121. This structure provides better protection for the electromagnetic wave radiation component 12 and reduces the risk of being broken by external forces.

[0053] Please refer to Figure 5 , Figure 5 which is the first circuit schematic diagram of the heating module provided by the embodiment of the present application. The heating module 10 further includes a power supply 15, a voltage regulating circuit 16, and a radio frequency chip 17. These components cooperate to achieve the conversion of electrical energy into thermal energy and precise control. The power supply 15 uses a lithium battery to supply power to the voltage regulating circuit 16 and the radio frequency chip 17. The voltage regulating circuit 16 can flexibly adjust the output voltage according to the signal of 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 according to temperature feedback.

[0054] In some embodiments, please refer to Figure 6 and Figure 7 , Figure 6 which is the fourth structural schematic diagram of the heating module provided by the embodiment of the present application, Figure 7 and

[0055] which is the fifth structural schematic diagram of the heating module provided by the embodiment of the present application. The heating module 10 further includes a heat insulation member 13, and the heat insulation member 13 is sleeved on the outer peripheral side of the electromagnetic wave radiation component 12. The heat insulation member 13 is a component with good heat insulation performance. 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 at the same time protect the surrounding components from being affected by high temperature, ensuring the safety and stability of the heating module 10. The material of the heat insulation member 13 can also be an insulating material, which can have the function of protecting and fixing the electromagnetic wave radiation component 12.

[0056] Among them, the insulating member 11 and the heat insulation member 13 are made of the same material. For example, the materials of the insulating substrate and the heat insulation layer are both PI. The PI film has the characteristics of insulation and high temperature resistance. During the processing process, since the insulating member 11 and the heat insulation member 13 are made of the same material, the processing technology and equipment can be universal, improving the production efficiency.

[0057] The thickness of the insulating member 11 is less than that of the heat insulating member 13. The insulating member 11 mainly functions as insulation and support. A relatively thin thickness can meet the requirements of its insulation performance, and at the same time, it will not occupy too much space, which is beneficial to the miniaturized design of the heating module 10. The heat insulating member 13 needs to withstand higher temperatures and greater heat transfer pressures. A thicker thickness can provide better heat insulation effects, ensuring that the heat generated by the electromagnetic wave radiation component 12 will not be transferred to the surrounding environment. For example, in the embodiments of the present application, the thickness of the insulating member 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 insulating member 13 is greater than 1 mm, such as 1.5 mm, 2 mm, 3 mm, 5 mm, etc. Considering the above situation, when both the insulating substrate and the heat insulating layer are made of PI films, the thickness of a single-layer PI film is 0.01 mm to 0.1 mm. The insulating member 11 can be composed of a single layer, a double layer, 5 layers, 7 layers or 8 layers of PI films stacked together, and the heat insulating member 13 can be composed of dozens of layers such as 10 layers to 50 layers of PI films stacked together. The heat insulating member 13 can effectively prevent heat transfer, keeping the temperature around the electromagnetic wave radiation component 12 within a safe range. At the same time, the insulating member 11 can also normally perform its insulation function.

[0058] In the electronic cigarette device 100, using such a heating module 10 can improve the heating efficiency, enabling the smoking material to reach a suitable temperature faster and generating a richer and more stable aerosol. At the same time, the protective effect of the heat insulating member 13 can extend the service life of the electromagnetic wave radiation component 12, reducing damage and failures caused by overheating.

[0059] In addition, since the insulating member 11 and the heat insulating member 13 are made of the same material, the overall structure of the heating module 10 is more concise, facilitating assembly and maintenance. During the production process, this design is also beneficial to quality control, improving the reliability and stability of the product.

[0060] Compared with the existing heating module 10, the heating module 10 in the embodiments of the present application has more obvious advantages. In the existing heating module 10, the insulating member 11 and the heat insulating member 13 may adopt different materials, which not only increases the complexity and cost of material procurement, but also makes it difficult to make the processing technology and equipment universal, resulting in low production efficiency. Moreover, there may be differences in physical properties such as the coefficient of thermal expansion between different materials. During long-term use, problems such as component loosening and damage caused by inconsistent thermal expansion and contraction are likely to occur, affecting the stability and service life of the heating module 10.

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

[0062] Both the first antenna radiator 122 and the second antenna radiator 123 are disposed around the outer surface of the insulating member 11. This surrounding arrangement can make full use of the space on the outer surface of the insulating member 11 to make the microwave radiation more uniform. The first antenna radiator 122 and the second antenna radiator 123 are spaced apart to avoid mutual interference between the first antenna radiator 122 and the second antenna radiator 123, and ensure the independence and stability of the microwave signals.

[0063] Please continue to refer to Figure 8 and Figure 9 , the bridging member 124 is electrically connected to the first antenna radiator 122 and the second antenna radiator 123 respectively. The bridging member 124 is made of a metal material with good electrical conductivity to ensure firm connection with the first antenna radiator 122 and the second antenna radiator 123 and the minimum resistance. Through this reliable electrical connection, the microwave signals 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 member 124 can be integrally formed. Integral forming is a manufacturing process that refers to manufacturing the first antenna radiator 122, the second antenna radiator 123, and the bridging member 124 simultaneously in one forming process through specific molds and processes. This process can avoid problems such as part fitting errors and loose connections that may occur in traditional assembly methods, and improve the overall performance and reliability of the component. The integral forming design enables the electromagnetic wave radiation 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 member 124, microwave signals can be smoothly transmitted between the two, reducing signal attenuation and interference.

[0065] In some cases, the first antenna radiator 122 and the second antenna radiator 123 are arranged at intervals along the axial direction of the insulating member 11. The axial direction refers to the central axis direction of the insulating member 11, that is, 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 in the length direction of the insulating member 11. This setting method can form different radiation regions for microwaves in the axial direction to meet the heating requirements of smoke-generating materials with 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 materials are uniformly irradiated by microwaves throughout the entire length range, improving the heating effect.

[0066] In other cases, the first antenna radiator 122 and the second antenna radiator 123 are arranged at intervals along the circumferential direction of the insulating member 11. The circumferential direction refers to the direction around the central axis of the insulating member 11 for one week, that is, the circumferential direction of the outer surface of the insulating member 11. The first antenna radiator 122 and the second antenna radiator 123 are evenly distributed in the circumferential direction of the insulating member 11. This setting method can form a uniform radiation field for microwaves in the circumferential direction, avoiding the situation of too strong or too weak local radiation. For example, around a circular smoke-generating material, the first antenna radiator 122 and the second antenna radiator 123 arranged at circumferential intervals can ensure that each position on the surface of the smoke-generating material receives microwave radiation of the same intensity, ensuring the uniformity of heating.

[0067] Among them, please continue to refer to Figure 8 and Figure 9 , the first antenna radiator 122 includes a first antenna radiation segment 1221, and the first antenna radiation segment 1221 extends in a surrounding arrangement or a reciprocating arrangement.

[0068] It can be understood that by adjusting the number of lines, length, thickness, etc., material and thickness of the first antenna radiation segment 1221, the electromagnetic wave emission frequency and emission intensity are adjusted, and the water molecules in the smoke-generating material are made to move and generate friction through high-frequency electromagnetic waves, so as to achieve the purpose of heating.

[0069] Please continue to refer to Figure 8 , when the first antenna radiation segment 1221 extends in a circumferential arrangement, like a coil surrounding the outer surface of the insulating member 11, it can generate a relatively uniform microwave radiation field. This arrangement is suitable for occasions with high requirements for heating uniformity. The circumferentially arranged and extending antenna radiation segment can ensure that the object to be heated receives the same microwave radiation in all directions, thereby achieving precise temperature control.

[0070] Please continue to refer to Figure 9 , when the first antenna radiation segment 1221 extends in a reciprocating arrangement, it will form a strong microwave radiation in some areas. This arrangement is suitable for occasions with high requirements for local heating. The reciprocatingly arranged and extending antenna radiation segment can concentrate the microwave energy and improve the heating efficiency of the local area.

[0071] The second antenna radiator 123 includes a second antenna radiation segment 1231. The second antenna radiation segment 1231 extends in a circumferential arrangement or a reciprocating arrangement, which is similar to the structure and technical effects of the first antenna radiator 122, and will not be elaborated here.

[0072] Please continue to refer to Figure 8 and Figure 9 , when the electromagnetic wave radiation component 12 is deployed into a plane, the first antenna radiator 122 and the second antenna radiator 123 can be arranged in a mirror symmetry or a central symmetry. These two symmetry arrangement methods each have unique advantages, which will be elaborated in detail below.

[0073] Please refer to Figure 8 (1), Figure 9 (2) to Figure 9 (5), the mirror symmetry arrangement means that the first antenna radiator 122 and the second antenna radiator 123 are in a mirror image relationship with respect to a certain plane, so that similar radiation fields are formed on both sides of the plane. From a physical principle perspective, when the microwave signal is transmitted from the microwave source to the antenna radiator, due to the mirror-symmetric structure, the distribution and propagation mode of the microwave on the two antenna radiators are consistent, thus ensuring the symmetry of the radiation field.

[0074] Please refer to Figure 8 (2) and Figure 9 (1), the central symmetry arrangement means that the first antenna radiator 122 and the second antenna radiator 123 are centrally symmetric with respect to a certain point, and can achieve omnidirectional uniform microwave radiation. Since the two antenna radiators are symmetrically distributed around the center point, the microwave signal can be evenly diffused and propagated in space, avoiding the situation of too strong or too weak local radiation.

[0075] In some embodiments, please refer to Figure 10 ,Figure 10 The sixth structural schematic diagram of the heating module provided by the embodiment of the present application: Figures (1) to (2) are two different structures of the heating module. The shape of the cross-section of the electromagnetic resonance cavity 121 along the axial direction is elliptical, cylindrical, such as Figure 10 (1), or frustum-shaped, such as Figure 10 (2), any one of them.

[0076] The electromagnetic resonance cavity 121 with an elliptical cross-section has a unique microwave propagation mode. Due to the geometric characteristics of the ellipse, when the microwave propagates in the cavity, it will reflect back and forth between the two foci, forming a relatively concentrated energy distribution. This concentrated energy distribution helps to improve the interaction efficiency between the microwave and the fuming material, making the heating more concentrated and efficient.

[0077] The manufacturing process of the electromagnetic resonance cavity 121 with a cylindrical cross-section is relatively simple and the cost is low. At the same time, the cylindrical resonance cavity can provide a relatively uniform microwave field distribution. In the cylindrical resonance cavity, the microwave propagates uniformly in the circumferential direction, so that the fuming material is subjected to similar microwave radiation intensities in all directions, thus ensuring the uniformity of heating.

[0078] The electromagnetic resonance cavity 121 with a frustum-shaped cross-section can adjust the distribution of the microwave to a certain extent. Due to the different sizes of the upper and lower bases of the frustum, when the microwave propagates in the cavity, it will gradually converge towards the smaller base, thereby forming a higher energy density in this area. This characteristic enables the frustum-shaped resonance cavity to meet the heating requirements of fuming materials with 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, which can provide more sufficient insulation protection for the electromagnetic wave radiation component 12. During the operation of the heating module 10, the electromagnetic wave radiation component 12 will generate a high-frequency electric field. If the insulation protection is insufficient, safety problems such as electrical short circuits may occur. And the longer insulating member 11 can ensure that there is enough insulation distance between the electromagnetic wave radiation component 12 and the surrounding environment, effectively preventing the occurrence of electric leakage, and improving the safety and reliability of the heating module 10. The projection of the electromagnetic wave radiation component 12 in the direction perpendicular to the axial length of 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 enables the electromagnetic wave radiation component 12 to be firmly fixed on the insulating member 11, avoiding displacement during operation due to vibration or external force, 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 the pin 14 is closely connected to the electromagnetic wave radiation component 12 to ensure stable transmission of the electrical signal and energy from the electromagnetic wave radiation component 12. The other end is exposed at the edge of the insulating member 11. Such a layout not only facilitates connection to an external circuit or other devices but also, to a certain extent, avoids interference to the pin 14 from the complex electromagnetic environment inside the insulating member 11.

[0081] The pin 14 enables the heating module 10 to more conveniently and efficiently achieve electrical connection and signal interaction when working in cooperation with other components, providing a strong guarantee for the stable operation and performance of the cooperative work. At the same time, it also brings great convenience to the installation, debugging, and maintenance of the heating module 10.

[0082] Please refer to Figure 11 and Figure 12 , Figure 11 which is the first structural schematic diagram of the electronic cigarette device provided by the embodiment of the present application, Figure 12 is Figure 11 the explosion structural schematic diagram of []. The embodiment of the present application also provides an electronic cigarette device 100. The electronic cigarette device 100 is a device that imitates a traditional cigarette and generates an aerosol for users to inhale by means of electronic heating of a smoking material.

[0083] The electronic cigarette device 100 includes the heating module 10, an electromagnetic shielding housing 20, a first fixing member 30, and a second fixing member 40 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 smoking material. Its performance directly affects the heating efficiency, uniformity, and stability of the electronic cigarette device 100. In the present electronic cigarette device 100, the heating module 10 adopts the structure with the specific cross-sectional shape of the electromagnetic resonance cavity 121, the axial length relationship between the insulating member 11 and the electromagnetic wave radiation component 12, etc. mentioned above.

[0085] The electromagnetic shielding housing 20 is sleeved outside the heating module 10, and the length of the electromagnetic shielding housing 20 is greater than the length of the electromagnetic wave radiation component 12. The electromagnetic shielding housing 20 is a housing made of metal or other conductive materials sleeved outside the heating module 10, and the electromagnetic shielding housing 20 is grounded. The main function of the electromagnetic shielding housing 20 is to effectively shield the electromagnetic radiation generated when the heating module 10 works, minimizing interference to the human body and surrounding electronic devices to the greatest extent. On the other hand, it can also provide a certain degree of protection for the heating module 10 to avoid physical damage from the outside.

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

[0087] The air layer can effectively block the heat generated when the heating module 10 works from being transferred to the electromagnetic shielding housing 20. Since the heating module 10 generates a relatively high temperature during operation, if effective heat insulation is not carried out, the heat is easily conducted to the outer shell of the electronic cigarette device 100, causing the outer shell to become hot, affecting the user experience, and even potentially causing safety hazards due to being scalded.

[0088] Please refer to Figure 13 , Figure 13 which is the second circuit schematic diagram of the heating module provided by the embodiment of the present application.

[0089] In the application of the electronic cigarette device 100, the electromagnetic resonance cavity 121 converts microwave into heat energy to atomize the smoking material. A temperature sensor 18 is provided in the electromagnetic resonance 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 the adaptive PWM modulation technology to adjust the pulse width of the PWM signal according to the difference between the temperature and the set value, control the voltage regulation circuit 16 to change the output voltage, and then precisely control the output of the microwave pulse power, so that the heating temperature of the electronic cigarette device 100 is stabilized within the set range.

[0090] When the heating module 10 works, the power supply 15 supplies power to the radio frequency chip 17, and the radio frequency chip 17 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 microwave, and the microwave heats the smoking material after passing through the insulating member 11. When the microwave continues to propagate and hits the electromagnetic shielding housing 20, it will be reflected back, so as to be restricted within the electromagnetic resonance cavity 121, realizing the all-round continuous heating of the smoking material, ensuring the heating effect and stability.

[0091] Please continue to refer to Figure 11 , Figure 14 and Figure 15 , Figure 14 which is the third structural schematic diagram of the electronic cigarette device provided by the embodiment of the present application, Figure 15 which is the fourth structural schematic diagram of the electronic cigarette device provided by the embodiment of the present application.

[0092] The first fixing member 30 may be an upper structural member, also known as an end cap. The material of the first fixing member 30 may be a high-temperature resistant insulating material. The first fixing member 30 can be used to connect and fix smoking materials such as cigarette rods and fix other structures of the electronic cigarette device 100. The first fixing member 30 is a component provided at one end of the electromagnetic shielding housing 20 and is used to fix the heating module 10. A stable connection is achieved between the first fixing member 30 and the heating module 10 through a specific connection method, ensuring the position of the heating module 10 in the electronic cigarette device 100 is fixed and guaranteeing the normal operation of the electronic cigarette device 100.

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

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

[0095] The first fixing member 30 and the second fixing member 40 are respectively provided at both ends of the electromagnetic shielding housing 20 and form a stable connection relationship with the heating module 10. This design method of fixing at both ends can provide stronger support and stability compared to single-end fixing, reducing the vibration and displacement of the heating module 10 during operation, thereby improving the accuracy and stability of heating.

[0096] Please refer to Figure 16 , Figure 16This is the fifth structural schematic diagram of the electronic cigarette device provided by the embodiments of the present application. When the heating module 10 is connected to the first fixing member 30, a limiting groove 31 is provided on the side of the first fixing member 30 facing the heating module 10, and the heating module 10 is embedded in the limiting groove 31 in an interference fit manner. This connection method has many advantages. The limiting groove 31 can be an annular limiting groove 31. When the heating module 10 is embedded in the limiting groove 31, one side of the heating module 10 placed in the limiting groove 31 will show a state of outward expansion, and the overall shape is similar to a horn shape. 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 during operation due to vibration or external force, ensuring the stability and reliability of the entire system; moreover, this horn-shaped structure also 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] In terms of connection strength, the interference fit can generate a large frictional force 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 working conditions, such as shaking during carrying, vibration during suction, etc. The interference fit connection method can effectively prevent 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 accurately limit the position of the heating module 10, enabling it to be quickly and accurately positioned during installation. This helps to improve the assembly efficiency of the electronic cigarette device 100, and at the same time ensures the relative position accuracy between the heating module 10 and other components, ensuring the performance consistency of the electronic cigarette device 100.

[0099] In addition, the interference fit also has a certain degree of sealing performance. In the electronic cigarette device 100, there may be some tiny gaps around the heating module 10. If not sealed, it may lead to aerosol leakage or entry of external impurities. The interference fit connection method can, to a certain extent, fill these gaps, reduce the risk of aerosol leakage, and at the same time prevent external dust, water vapor and other impurities from entering the interior of the electronic cigarette device 100 and affecting the performance and service life of the heating module 10.

[0100] In the heating module 10 and the electronic cigarette device 100 provided by the embodiments of the present application, 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 receiving the smoking material; the electromagnetic wave radiation component 12 is disposed around the outer surface of the insulating member 11 to form an electromagnetic resonance cavity 121. At least a part of the receiving cavity is located within the electromagnetic resonance cavity 121. The heating module 10 can reduce the risk of the electromagnetic wave radiation component 12 being contaminated and broken. In the design of the existing heating module 10, the electromagnetic wave radiation component 12 often directly contacts the smoking material or is relatively close thereto, which easily causes the electromagnetic wave radiation component 12 to be contaminated by impurities, moisture, etc. in the smoking material, thereby affecting its performance and service life. In the heating module 10 of the embodiments of the present application, the insulating member 11 isolates the electromagnetic wave radiation component 12 from the smoking material, effectively avoiding direct contact and greatly reducing the possibility of the electromagnetic wave radiation component 12 being contaminated. In addition, in some traditional heating modules 10, the structure of the electromagnetic wave radiation component 12 is relatively fragile and easily broken under the action of 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 collision, extrusion, etc. In the heating module 10 of the embodiments of the present application, the electromagnetic wave radiation component 12 is disposed around the outer surface of the insulating member 11 to form the electromagnetic resonance cavity 121, and this structure provides better protection for the electromagnetic wave radiation component 12 and reduces the risk of being broken under the action of external forces.
