The output voltage of the power supply and the operating voltage of the heating element usually differ, and the heating element needs to be converted before it can work normally. Generally, the heater includes a plurality of heating elements, and the plurality of heating elements are arranged in series, resulting in a large change in the operating voltage required by the heating element compared to the output voltage of the power supply, reducing the conversion efficiency and affecting the working efficiency of the heater. SUMMARY

[0032] In related technologies, aerosol generating devices include a power supply and a heater. The power supply powers the heater, causing its heating elements to generate heat and heat the aerosol generating matrix. The output voltage of the power supply usually differs from the operating voltage of the heating elements, requiring voltage conversion before the heating elements can operate normally. Generally, the heater includes multiple heating elements connected in series, resulting in a significant variation in the operating voltage required by the heating elements compared to the power supply's output voltage. This reduces conversion efficiency and affects the heater's overall efficiency. To address this issue, please refer to [reference needed]. Figure 1 This application provides a heater 100 and an aerosol generating device 1000.

[0033] Please see Figure 1 The aerosol generating apparatus 1000 of this application includes a heater 100 and an electrical control component 300, wherein the heater 100 and the electrical control component 300 are electrically connected.

[0034] It is understood that heater 100 is a structure in aerosol generating apparatus 1000 capable of heating the aerosol generating matrix to generate aerosols. The aerosol generating matrix is ​​a processed product capable of generating aerosols under heating, ultrasonication, or mechanical vibration. The aerosol generating matrix can be in a liquid state, or in a fully solid or semi-solid state. The aerosols can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor.

[0035] The electronic control component 300 is a structure in the aerosol generating apparatus 1000 used to control the operation of the heater 100. In some embodiments of this application, the electronic control component 300 includes a power supply 310 and a controller 330. The power supply 310 provides electrical energy to the heater 100. The controller 330 is electrically connected to the power supply 310 and is used to regulate the voltage of the electrical energy. Exemplarily, when the aerosol generating apparatus 1000 is being evacuated, the controller 330 can control the power supply 310 to output electrical energy to the heater 100 and regulate the voltage of the electrical energy output by the power supply 310 so that the adjusted voltage is suitable for the heater 100. In this case, the heater 100 can heat and atomize the aerosol generating matrix to generate aerosols. When the aerosol generating apparatus 1000 is not being evacuated, the controller 330 can control the power supply 310 to stop providing electrical energy to the heater 100. In this case, the heater 100 will not heat the aerosol generating matrix. It is understood that the controller 330 includes a voltage regulation circuit, and the power supply 310 and the heater 100 are both electrically connected to the voltage regulation circuit. The voltage regulation circuit can regulate the voltage of the electrical energy output by the power supply 310 (boost or reduce the voltage) so that the adjusted voltage is suitable for the heater 100.

[0036] It should be noted that in some embodiments, the power supply 310 can be a dry cell battery or a rechargeable battery, including but not limited to lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries. For example, the power supply 310 includes a single battery cell with a voltage of 3.7V or 3.85V; as another example, the power supply 310 includes two batteries with a voltage of 7.4V or 7.7V.

[0037] Furthermore, in some embodiments, the aerosol generating device 1000 further includes a housing 500, in which the heater 100 and the electronic control components 300 are all disposed. Specifically, the housing 500 is a structure in the aerosol generating device 1000 that can accommodate and protect the heater 100 and other devices. The material of the housing 500 includes, but is not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. In one example, the housing 500 may be made of plastic, which makes the housing 500 lighter and facilitates the portability of the aerosol generating device 1000. In another example, the housing 500 may be made of a high-temperature resistant material, which can prevent the housing 500 from being damaged by heat (e.g., deformation) and ensure the stability and reliability of the aerosol generating device 1000. High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK), high-melting-point metals, and high-temperature ceramics.

[0038] Since the aerosol generating device 1000 in this embodiment includes a heater 100, it is understood that the aerosol generating device 1000 has at least the same beneficial effects as the heater 100. Therefore, for the beneficial effects of the aerosol generating device 1000, please refer to the beneficial effects of the heater 100 described below.

[0039] Please see Figure 1 and combined Figure 2 or Figure 4 In some embodiments, the heater 100 can heat the object being heated through direct contact. For example, the heater 100 can directly convert other forms of energy, such as electrical energy, chemical energy, or solar energy, into heat energy and conduct it to other parts that need to be heated via heat transfer. In other embodiments, the heater 100 can heat the object without contact. For example, the heater 100 emits other forms of energy, such as electromagnetic waves, lasers, infrared light, or thermal radiation, that can directly act on the surface of the part to be heated, thereby raising the temperature of the area receiving the electromagnetic waves, lasers, infrared light, or thermal radiation.

[0040] In some embodiments of this application, the heater 100 can emit a laser beam towards the aerosol generating matrix, which irradiates and heats the matrix to generate aerosols. Using laser heating of the aerosol generating matrix enables rapid aerosol generation, reducing the time required for the matrix to generate aerosols while the aerosol generating device 1000 is being aspirated. This ensures the freshness of the aerosols each time the user aspirates and allows the aerosol generating device 1000 to achieve a "pump and stop" effect, improving the user's aspiration experience.

[0041] Please see Figure 2 and Figure 3 ,or Figure 4and Figure 5 The heater 100 of the present application includes a substrate 11 and a plurality of heating modules 13. The plurality of heating modules 13 are connected in series on the substrate 11. Each heating module 13 includes at least two heating elements 131. The at least two heating elements 131 are connected in parallel. The heating module 13 is used to generate heat by passing electricity to heat the aerosol to generate a matrix.

[0042] It is understood that the substrate 11 is a structure in the heater 100 used to mount components other than the substrate 11. Components other than the substrate 11 in this document include, but are not limited to, the heating element 131. The outer contour shape of the substrate 11 may include, but is not limited to, cylinders, cubes, cuboids, triangular prisms, and hexagonal prisms. The material of the substrate 11 includes, but is not limited to, plastics, glass, ceramics, and metals. In some embodiments of this application, the substrate 11 is made of at least one of aluminum nitride (AlN) and aluminum oxide. It is understood that the substrate 11 provides support for the mounting of components such as the heating module 13 in the heater 100; on the other hand, it absorbs the heat generated by the heating module 13 and dissipates the absorbed heat to the surrounding structural components, thereby preventing heat accumulation that could damage the heating module 13, ensuring controllable heat from the heating module 13, extending the service life of the heating module 13, and ensuring the normal operation of the heater 100.

[0043] The heating module 13 is a structure in the heater 100 used to heat the aerosol generation matrix. In some embodiments of this application, each heating module 13 includes at least two heating elements 131, and the heating elements 131 include laser chips, such as VCSEL (Vertical-Cavity Surface-Emitting Laser) chips. Exemplarily, when the heater 100 is working, at least one of the multiple heating modules 13 is energized to heat the aerosol generation matrix. That is, the multiple heating modules 13 in the heater 100 can heat the aerosol generation matrix in an independent, alternating, or combined manner, thereby increasing the number of power levels of the heater 100 and effectively meeting the user's needs.

[0044] It is understandable that multiple heating modules 13 connected in series can be configured such that they are connected end-to-end to form a single current path. The current flowing through each heating module 13 is the same, and the voltage provided by the electronic control component 300 to the heater 100 (i.e., the converted voltage, hereinafter referred to as the "input voltage") is equal to the sum of the voltages across each heating module 13. At least two heating elements 131 connected in parallel can be configured such that the two ends of at least two heating elements 131 are connected together, so that each element is connected to the two ends of the power supply 310. The voltages across at least two heating elements 131 are the same, i.e., equal to the input voltage, and the current provided by the electronic control component 300 to the heater 100 (hereinafter referred to as the "input current") is equal to the sum of the currents in each heating element 131.

[0045] Please combine Figure 2 and Figure 3 In some embodiments, the heating module 13 includes three units, and each heating module 13 includes two heating elements 131. The input voltage is 10V, the input current is 3.6A, and the average input power of the multiple heating modules 13 is 36W.

[0046] Understandably, when all heating elements 131 in the three heating modules 13 are connected in series, to ensure that the current flowing through each heating element 131 (1.8A) and the input power (36W) of the multiple heating modules 13 remain constant, the input voltage needs to be increased to 20V. This input voltage difference compared to the output voltage of the power supply 310 (e.g., 3.7V) is too large, resulting in reduced conversion efficiency. Therefore, the technical solution in this embodiment, compared to connecting the heating elements 131 of the multiple heating modules 13 in series, exhibits a smaller voltage variation and better voltage conversion efficiency. This not only improves the working efficiency of the heater 100 but also reduces the energy consumption of the aerosol generator 1000 and extends its operating time.

[0047] Please combine Figure 4 and Figure 5 In other embodiments, the heating module 13 includes three units, and each heating module 13 contains four heating elements 131. The input voltage is 10V, the input current is 3.6A, and the average input power of the multiple heating modules 13 is 36W.

[0048] Understandably, when all heating elements 131 in the three heating modules 13 are connected in series, to ensure that the current flowing through each heating element 131 (0.9A) and the input power (36W) of the multiple heating modules 13 remain constant, the input voltage needs to be increased to 40V. This input voltage difference compared to the output voltage of the power supply 310 (e.g., 3.7V) is too large, resulting in reduced conversion efficiency. Therefore, the technical solution in this embodiment, compared to connecting the heating elements 131 of the multiple heating modules 13 in series, exhibits a smaller voltage variation and better voltage conversion efficiency. This not only improves the working efficiency of the heater 100 but also reduces the energy consumption of the aerosol generator 1000 and extends its operating time.

[0049] In some embodiments, the heating module 13 is supported on the substrate 11, that is, the entire heating module 13 is located on the outside of the substrate 11. This facilitates the installation of the heating module 13 and improves assembly efficiency; on the other hand, it reduces the possibility of light emitted by the heating module 13 to the aerosol generating matrix being blocked, ensuring normal heating of the aerosol generating matrix by the heating module 13. In other embodiments, at least a portion of the heating module 13 is embedded in the substrate 11, which reduces the space occupied by the heating module 13 and facilitates the miniaturization of the heater 100.

[0050] In the heater 100 of this application embodiment, a plurality of heating modules 13 are connected in series on the base 11. Each heating module 13 includes at least two heating elements 131, and the at least two heating elements 131 are connected in parallel. Therefore, compared with the heating elements 131 of the plurality of heating modules 13 being connected in series, the voltage change is smaller during the voltage conversion process, and the voltage conversion efficiency is better. This not only improves the working efficiency of the heater 100, but also reduces the energy consumption of the aerosol generating device 1000 and extends the battery life of the aerosol generating device 1000.

[0051] Furthermore, compared to multiple heating modules 13 where the heating elements 131 are connected in series, the current flowing through each heating element 131 is smaller, which, combined with the heat loss calculation formula W=IR 2 It can be seen that the heat loss of the heating module 13 is relatively small, allowing more of the heat generated by the heating module 13 to act on the aerosol generating matrix, thereby improving the thermal efficiency of the heating module 13 and reducing the aerosol generating device 1000 ( Figure 1 (As shown) reduce energy consumption and extend the operating time of the aerosol generator 1000.

[0052] The heater 100 will be further described below with reference to the accompanying drawings.

[0053] Please see Figure 2 or Figure 4In some embodiments, the heater 100 further includes a conductive element 15 disposed on the substrate 11 and electrically connected to the heating module 13. The conductive element 15 is used to transmit electrical energy to the heating module 13.

[0054] Specifically, please combine Figure 1 In some embodiments, one end of the conductive element 15 is electrically connected to the positive terminal of the power supply 310, and the other end is electrically connected to the negative terminal of the power supply 310. Thus, electrical energy from the power supply 310 can be transferred to the heating module 13 through the conductive element 15, causing the heating module 13 to generate heat and heat the aerosol to form the matrix. Furthermore, the conductive element 15 is disposed on the substrate 11, thereby allowing heat from the conductive element 15 to be quickly conducted to the substrate 11, ensuring that the temperature of the conductive element 15 is controllable, preventing overheating and damage, extending the service life of the conductive element 15, and improving the stability and reliability of the heater 100.

[0055] In some embodiments, the conductive element 15 and the substrate 11 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connection, threaded connection, etc. In other embodiments, the conductive element 15 and the substrate 11 can be joined together by a non-detachable connection method, including but not limited to welding, gluing, interference fit, etc.

[0056] Further, please refer to Figure 2 and Figure 3 ,or Figure 4 and Figure 5 In some embodiments, the conductive element 15 includes a first conductive portion 151, a second conductive portion 153, and a third conductive portion 155, which are connected in series via multiple heating modules 13. It should be noted that in some embodiments, the first conductive portion 151, the second conductive portion 153, and the third conductive portion 155 are separate structures, i.e., the first conductive portion 151, the second conductive portion 153, and the third conductive portion 155 are three different structures.

[0057] Specifically, in some embodiments, the first conductive part 151 can be electrically connected to the positive terminal of the power supply 310, the third conductive part 155 can be electrically connected to the negative terminal of the power supply 310, the second conductive part 153 is disposed between the first conductive part 151 and the third conductive part 155, and one end of the second conductive part 153 is electrically connected to the first conductive part 151 through a heating module 13, and the other end of the second conductive part 153 is electrically connected to the third conductive part 155 through another heating module 13. In this way, the first conductive part 151, the second conductive part 153 and the third conductive part 155 form a series circuit, and during the process of electrical energy flowing through the conductive part 15, the electrical energy can flow through multiple heating modules 13 in sequence, so that the heating modules 13 generate heat and heat the aerosol generating device 1000.

[0058] In some embodiments, the conductive element 15 is made of materials including, but not limited to, gold, copper, nickel, graphite, and conductive ceramics. The materials of the first conductive part 151, the second conductive part 153, and the third conductive part 155 may be the same or different. In some embodiments of this application, the second conductive part 153 includes at least two, and the first conductive part 151, at least two second conductive parts 153, and the third conductive part 155 are connected in series through multiple heating modules 13 to form a series circuit.

[0059] In some embodiments, the second conductive portion 153 includes a loading sub-portion 1531 and a conductive sub-portion 1533. The loading sub-portion 1531 is connected between a heating module 13 and the substrate 11. The conductive sub-portion 1533 is connected to the loading sub-portion 1531 and is electrically connected to another adjacent heating module 13.

[0060] Specifically, in some embodiments, the loading sub-part 1531 is connected between a heating module 13 and the base 11, and the conductive sub-part 1533 is connected to the loading sub-part 1531 and electrically connected to another adjacent heating module 13. Thus, most of the heat generated by the heating module 13 is conducted to the loading sub-part 1531, and a small amount of heat is conducted to the conductive sub-part 1533 through the loading sub-part 1531. Compared with the case where the conductive sub-part 1533 is not provided and the other adjacent heating module 13 is directly electrically connected to the loading sub-part 1531, the electrical connection between the heating module 13 and the second conductive part 153 is less affected by heat, thereby improving the stability of the electrical connection between the heating module 13 and the second conductive part 153 and ensuring the normal operation of the heater 100.

[0061] Furthermore, in some embodiments, the third conductive part 155 may include a first sub-part 1551 and a second sub-part 1553, the first sub-part 1551 being connected between the heating module 13 and the substrate 11, and the second sub-part 1553 being connected to the first sub-part 1551 and electrically connected to the electrical control component 300 of the aerosol generating device 1000.

[0062] Specifically, in some embodiments, the first sub-part 1551 is connected between the heating module 13 and the base 11, and the second sub-part 1553 is connected to the first sub-part 1551 and electrically connected to the electronic control component 300. Thus, most of the heat generated by the heating module 13 is conducted to the first sub-part 1551, and a small amount of heat is conducted to the second sub-part 1553 through the first sub-part 1551. Compared with the absence of the second sub-part 1553 and the direct electrical connection between the heating module 13 and the electronic control component 300, the electrical connection between the heating module 13 and the electronic control component 300 is less affected by heat, thereby improving the stability of the electrical connection between the heating module 13 and the electronic control component 300 and ensuring the normal operation of the heater 100.

[0063] For example, when the heating module 13 includes three components, namely a first heating module, a second heating module, and a third heating module, the second conductive part 153 includes two components. Specifically, the first conductive part 151 is electrically connected to the positive terminal of the power supply 310 and the first heating module; one of the two second conductive parts 153 has a loading sub-part 1531 for loading the first heating module, and its conductive sub-part 1533 is electrically connected to the second heating module; the other of the two second conductive parts 153 has a loading sub-part 1531 for loading the second heating module, and its conductive sub-part 1533 is electrically connected to the third heating module; the first sub-part 1551 of the third conductive part 155 is for loading the third heating module, and its second sub-part 1553 is electrically connected to the negative terminal of the power supply 310.

[0064] In some embodiments, the conductive part 1533 and the loading part 1531 are an integral structure, that is, the conductive part 1533 and the loading part 1531 can be integrally molded into a single structure. This reduces the number of parts, facilitating the assembly of the heater 100, and also improves the connection strength between the conductive part 1533 and the loading part 1531, reducing the possibility of separation between the conductive part 1533 and the loading part 1531 during the operation of the heater 100, thus ensuring the normal operation of the heater 100. In other embodiments, the conductive part 1533 and the loading part 1531 are separate structures, that is, the conductive part 1533 and the loading part 1531 are two different structures. The conductive part 1533 and the loading part 1531 can be connected together using either a non-detachable connection or a detachable connection. Non-detachable connection methods include, but are not limited to, bonding, welding, and interference fit; detachable connection methods include, but are not limited to, snap-fit ​​connections or threaded connections.

[0065] Please see Figure 2 or Figure 4In some embodiments, multiple heating modules 13 are arranged side-by-side on the substrate 11. This, compared to multiple heating modules 13 being arranged non-side-by-side on the substrate 11, prevents the heat generated by the heating modules 13 from dispersing into the surrounding environment, allowing the heat generated by the multiple heating modules 13 to act more concentratedly on the target heating area on the aerosol generating matrix. This enables the aerosol generating matrix to reach the temperature for aerosol generation more quickly, improving aerosol generation efficiency and ensuring the user's inhalation experience.

[0066] Furthermore, in some embodiments, the heater 100 includes at least one row of heating elements 131 distributed along the arrangement direction X of the heating module 13.

[0067] Specifically, please combine Figure 2 In some embodiments, the heater 100 includes a row of heating elements 131 distributed along the arrangement direction X of the heating modules 13, that is, the heating elements 131 of the multiple heating modules 13 are arranged in a single row on the substrate 11. The single-row distribution of heating elements 131 can make the structure of the heater 100 simpler and facilitate the user to maintain and replace the heating elements 131.

[0068] Please combine Figure 4 In other embodiments, the heater 100 includes multiple rows of heating elements 131 distributed along the arrangement direction X of the heating modules 13, that is, the heating elements 131 of the multiple heating modules 13 are distributed in multiple rows on the substrate 11. The multiple rows of heating elements 131 can make the temperature field more uniform, thereby enabling the aerosol generating matrix to be uniformly atomized, resulting in better consistency of taste; on the other hand, it can avoid the aerosol generating matrix from being heated unevenly, which would cause the generated aerosol to have a burnt taste, thus improving the user's inhalation experience.
