[0034] Existing heating modules made using antennas typically involve spirally winding a conductor material around an insulated central rod, either circumferentially or axially, forming a tubular circuit. An insulating material is then wrapped around the conductor. The central rod and the outer insulating material clamp and secure the conductor circuit. Together, the central rod, conductor, and outer insulating material constitute the radiating portion of the microwave antenna. A feed section is then connected to one end of the tubular circuit. This method of creating a microwave antenna radiates microwaves to heat the cigarette. However, existing antennas suffer from complex manufacturing processes.

[0035] Please see Figures 1 to 4 In response, this application provides a heating module 100, including a base tube 10, a microwave antenna 20, and a connecting assembly. A smoke passage 11 is formed inside the base tube 10. The microwave antenna 20 is wound around the outside of the base tube 10 and is used to emit microwaves into the smoke passage 11 to heat the smoke stick inside the smoke passage 11. The connecting assembly includes at least a feed structure 31, which includes a main body 311 and an extension 312 connected to the main body 311. One end of the main body 311 is connected to the microwave antenna 20, and the other end is exposed outside the base tube 10. The extension 312 is at least partially embedded in the tube wall of the base tube 10.

[0036] In this embodiment, the feed structure 31 is at least partially embedded in the base tube 10, thereby enabling the feed structure 31 and the base tube 10 to be integrated into a single design. This avoids movement of the feed structure 31 during the use of the heating module 100, and also prevents relative movement between the feed structure 31 and the base tube 10 during the installation of the microwave antenna 20, eliminating the need for installation of the feed structure 31. This effectively reduces the installation difficulty of the microwave antenna 20.

[0037] It should be noted that the material of the base tube 10 is not limited, as long as it is an insulating material. In some embodiments, the base tube 10 is made of high-temperature resistant plastic material, such as PEEK, PPSU, PI, etc., which is not limited here. The microwave antenna 20 is made of PVD target material: it can be a conductor material with TCR properties, such as SUS316L. The microwave antenna 20 is used to emit microwaves into the smoke channel 11. The high-frequency electromagnetic waves cause the water molecules in the heated object to move and generate friction, thereby achieving the purpose of heating. The high-frequency electromagnetic waves cause the water molecules in the heated object to vibrate violently in the microwave high-frequency electromagnetic field. The molecular friction is converted into heat energy to heat the object. The advantage of this technology is that any object containing water molecules can be heated, reducing the heat absorption and heat transfer loss of traditional heating elements (conductive heating). It also has advantages such as fast heating speed, high efficiency and low heat loss. The feed structure 31 mainly serves to connect the PCB board and the microwave antenna 20.

[0038] It should be emphasized that the extension 312 is at least partially embedded in the wall of the base tube 10. Specifically, it can be embedded only partially or completely, which is not limited here. The specific embedding method is not limited. It can be snap-fit. Of course, in some embodiments, the base tube 10 is made of plastic material. In this case, it can also be directly embedded in the base tube 10 during in-mold injection molding, thereby making the embedding process simpler, etc., which are not limited here.

[0039] In a further embodiment, the main body 311 and the connection portion of the microwave antenna 20 are embedded in the base tube 10, and the extension portion 312 is buried in the base tube 10. This arrangement can effectively improve the stability of the connection between the base tube 10 and the feed structure 31, making the connection between the two tighter.

[0040] It should be noted that the shape of the microwave antenna 20 is not limited. It can be a spiral design, that is, a spiral rising shape, or a sheet-like design when unfolded, etc., and is not limited here.

[0041] Currently, microwave antennas 20 are generally designed in a spiral shape. This design requires the antenna to be wound around the base tube 10 in circles during installation, which is a relatively complex process. Therefore, in some embodiments, the microwave antenna 20 includes a connecting section 21 and two radiating sections 22 respectively disposed on both sides of the connecting section 21 in the circumferential direction of the base tube 10; one end of the connecting section 21 is connected to the feed structure 31, and the other end is connected to the two radiating sections 22.

[0042] In the scheme of this embodiment, by setting the microwave antenna 20 as a connecting section 21 and two radiating sections 22 respectively disposed on both sides of the connecting section 21 in the circumferential direction of the base tube 10, the microwave antenna 20 can be unfolded into a sheet shape. In the actual manufacturing process, the sheet-shaped microwave antenna 20 can be made first, and then the sheet-shaped microwave antenna 20 can be directly rolled on the outside of the base tube 10. Compared with the spiral antenna, the sheet-shaped antenna can be formed by rolling only once, without the need for multiple back-and-forth rolling.

[0043] Of course, please refer to the following carefully. Figure 3 In some embodiments, a layer of conductive material can be directly plated on the outside of the base tube 10, and then the excess conductive material layer can be removed by laser engraving to leave the required antenna line shape.

[0044] It should be noted that by setting the connecting section 21, it can contact the feed structure 31, thereby connecting to the PCB board and being controlled by the PCB board to emit microwaves. The two radiating sections 22 can effectively increase the area of ​​microwave antenna 20 to emit microwaves, making the microwave distribution in the smoke channel 11 more uniform and improving the uniformity of heating the smoke stick.

[0045] It should be noted that the existing heating module 100 cannot measure and control the temperature of the microwave antenna 20. Therefore, in some embodiments, the resistivity of the microwave antenna 20 is linearly related to its temperature. The feed structure 31 assembly also includes two temperature measuring pins 32, one end of which is connected to the microwave antenna 20, and the other end extends to the outside of the base tube 10.

[0046] Specifically, the resistivity of the microwave antenna 20 is linearly related to its temperature, that is, the resistivity of the microwave antenna 20 is different at different temperatures. Specifically, the microwave antenna 20 can be made of a conductor material with TCR characteristics, such as SUS316L, or other materials whose resistivity changes with temperature.

[0047] TCR (Temperature Coefficient of Resistance) refers to the characteristic that resistance changes with temperature; when the temperature changes, its resistance also changes accordingly.

[0048] In the scheme of this embodiment, by setting two temperature measuring pins 32, a resistance measuring circuit can be connected to the two temperature measuring pins 32 to measure the resistance of the part of the microwave antenna 20 located between the two temperature measuring pins 32. Then, the temperature value of the microwave antenna 20 can be calculated based on the resistance value, thus realizing accurate temperature measurement of the microwave antenna 20.

[0049] In addition, in some embodiments, a temperature control circuit can be provided on the external circuit. While measuring the temperature, the power of the microwave antenna 20 can be adjusted by the temperature control circuit to achieve the purpose of temperature control.

[0050] The specific placement of the two temperature measuring pins 32 on the microwave antenna 20 is not limited, as long as the two temperature measuring pins 32 can be connected through the microwave antenna 20. They can both be set on the connection section 21 of the feed structure 31, or both on the radiation section 22 of the feed structure 31, or both on one radiation section 22, or they can be set on two separate radiation sections 22, or one can be on the connection section 21 of the feed structure 31 and the other on the radiation section 22 of the feed structure 31, etc., and no limitation is made here.

[0051] In a further embodiment, the two temperature measuring pins 32 are respectively located in the two radiation sections 22 and are positioned near the feed structure 31.

[0052] In the technical solution of this embodiment, the two temperature measuring pins 32 are respectively located in the two radiation sections 22, thereby ensuring that there is a sufficiently long microwave antenna 20 between the two temperature measuring pins 32 for connection, thus ensuring the accuracy of the resistance measurement of the microwave antenna 20. The two temperature measuring pins 32 are set close to the feed structure 31, so that during the manufacturing process, the temperature measuring pins 32 and the feed structure 31 can be buried together in the base tube 10. When connecting, the close distance between the temperature measuring pins 32 and the feed structure 31 also makes it convenient for installers to connect them in one go.

[0053] It should be noted that the specific implementation of the temperature measuring pin 32 and the feed structure 31 can be the same or different, and no limitation is made here. In one embodiment, the specific implementation of the temperature measuring pin 32 and the feed structure 31 is configured to be the same, that is, both are made of the same material and have the same shape, thereby improving the versatility of the components.

[0054] The shape of the connecting segment 21 is not limited; it can be straight, curved, etc., and is not limited here. In some embodiments, the connecting segment 21 is bent back and forth in the radial direction of the base tube 10. Correspondingly, in this embodiment, the connecting segment 21 is bent back and forth, so that the microwave emitted by the connecting segment 21 has a larger coverage area and the magnetic field uniformity in the smoke passage 11 is better.

[0055] In some embodiments, the radiating segment 22 includes a plurality of transverse segments 221 and longitudinal segments 222 connected in sequence, wherein the spacing between any two adjacent longitudinal segments 222 is equal, and / or the spacing between any two adjacent transverse segments 221 is equal.

[0056] In the scheme of this embodiment, by setting the radiation segment 22 as a plurality of sequentially connected transverse segments 221 and longitudinal segments 222, and the spacing between each two adjacent longitudinal segments 222 is equal, and / or the spacing between each two adjacent transverse segments 221 is equal, the coverage area of ​​the radiation segment 22 and the uniformity of the generated magnetic field can be effectively improved.

[0057] If the microwave antenna 20 is fabricated by setting a coating on the outside of the base tube 10, the coating may easily stick to or adhere to the base tube 10. In some embodiments, the outer periphery of the base tube 10 is coated with a release mortar. Correspondingly, in the scheme of this embodiment, by coating the outer periphery of the base tube 10 with a release mortar, the phenomenon of the coating sticking to or adhering to the base tube 10 can be effectively avoided.

[0058] Specifically, the form of the separating adhesive is not limited; it can be a ceramic coating or an oxide layer, which can prevent the coating from adhering.

[0059] Please refer to this carefully. Figure 4 and Figure 5 In some embodiments, the heating module 100 further includes an isolation membrane 40, which is wrapped around the outside of the microwave antenna 20. In this embodiment, by setting the isolation membrane 40, the heat generated by the heating module 100 can be prevented from leaking out, reducing heat loss and improving heating efficiency.

[0060] Furthermore, in some embodiments, the microwave antenna 20 is disposed on the isolation membrane 40 and is rolled together with the isolation membrane 40 on the outside of the base tube 10.

[0061] In the actual manufacturing process, the microwave antenna 20 can be first deposited onto the isolation film 40, and then the isolation film 40 with the antenna lines deposited can be wound onto the outside of the base tube 10. With this arrangement, the microwave antenna 20 can be wound onto the outside of the base tube 10 at the same time as the isolation film 40 is wound, which simplifies the manufacturing process.

[0062] Specifically, in practice, it can be done directly... Figure 5 The separator 40 is in the rolling direction Figure 4 The outer side of the base tube 10 is rolled to obtain our heating module 100. The entire manufacturing process is simple.

[0063] This application also proposes an electronic cigarette device, which includes a heating module 100. The heating module 100 adopts one or all of the technical solutions of the foregoing embodiments, and therefore possesses all or all of the technical advantages of the foregoing embodiments.

[0064] The heating module and electronic cigarette device provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
